2018/03/20 | 648 | 2,343 | <issue_start>username_0: The idea is that I show a loading .gif file while I load the data and then once all the data has loaded, wait an `x` amount of time, currently 3000ms, but will be lowered, then after the given amount of time, set the value of data.show to true, so that the loading .gif is no longer showing and that the Table is.
So, how do I reference `show` from the JavaScript in the HTML, ng-show?
Any help would be appreciated!
Thanks :)
edit: This works regarding to this to answer - [setTimeout v $timeout](https://coderwall.com/p/udpmtq/angularjs-use-timeout-not-settimeout)
HTML
----
```
Stuff
```
JavaScript
----------
```
function onSuccess(response) {
controller.errors = response.data;
setTimeout(function () {
$('#errorTable').DataTable({
"lengthMenu": [[6], [6]],
"dom": '<"toolbar">frtip'
});
$("div.toolbar").html('');
$scope.show = true;
}, 3000);
}
```<issue_comment>username_1: Try adding `$scope.show = { data: false };` in the controller
Upvotes: 2 <issue_comment>username_2: The problem is you have not defined $scope.show in the beginning. You probably don't need show.data . Please add the following line at the beginning of the controller
```
$scope.show = false;
```
And Change html to:
```
Stuff
```
And in controller:
You have added the $scope.show.data outside setTimeout bring it within the setTimeout function as per your need and add:
```
function onSuccess(response) {
controller.errors = response.data;
$timeout(function () {
$('#errorTable').DataTable({
"lengthMenu": [[6], [6]],
"dom": '<"toolbar">frtip'
});
$("div.toolbar").html('');
$scope.show = true;
}, 3000);
}
```
[Here](https://embed.plnkr.co/pAI3lvNxRRGNeRi4toAl/) is the plunker that I tried

Simple solution could be to place the `$scope.show.data = true;` as the first statement in the `function` called by `setTimeout`.

2018/03/20 | 698 | 2,300 | <issue_start>username_0: I have a model `'user'` of two properties `'username'` & `'plan'` where `'plan'` is a reference of another model `'plan'` where properties are `'name'` & `'description'`. now when I use following Query in API to retrieve data-
```
`user.find().populate('plan')`
```
I am trying to render this data in front-end using
```
this.state.users.map(re => (
| {re.username} | {re.plan} |
)
```
Here `re.plan` returns the `_id` of the property. To get the `name` property, I have to use `re.plan.name` . Which returns an error as I have some properties which does not have any `plan` property.
Sample data from the Query ---
```
{
"_id": "5a8be9ce4f506927a8d2cacb",
"username": "kjbfhisdugfiasdb",
"plan": {
"_id": "5a64bbd3f671402b90ce5fc9",
"name": " test 3"
},
},
{
"_id": "5a82bcb4c72440221442399f",
"username": "test",
}
```
How to resolve this issue?

I can see that the last time it has been built is `Dec 31 17:46:18 AEST 2015`. In your .war file there is a file inside `HatAndScarf\META-INF\maven\josh\Assignment2` which exposes this information:
```
#Generated by Maven
#Thu Dec 31 17:46:18 AEST 2015
version=1.0
groupId=josh
artifactId=Assignment2
```
I think if you try to build it via maven and then redeploy it the problem should go away.

```
# Browser: CHROME, CHROME_NOHEAD, FF32, FF32_NOHEAD, FF64, FF64_NOHEAD
# EDGE, IE32, IE64
browser=oPerA

I set up the switch with a default clause:
```
public class ServiceHook {

break;
case CHROME_NOHEAD: break;

Any advice why it does not trigger default clause?<issue_comment>username_1: The code doesn't get that far.
It's the `Browser browser = Browser.valueOf(browserConfig.toUpperCase());` that throws the Exception. You have to put that in a try-catch block to handle invalid values.

2018/03/20 | 1,049 | 3,543 | <issue_start>username_0: Consider the following code
```
import numpy as np
a = np.array([1,2])
b = np.array([3,4])
c = [a,b]
np.sum(x for x in c) # array([4,6])
np.sum(c) # 10
```
What is the rationale behind treating lists different from generator expressions?<issue_comment>username_1: Generator expression yields or generates one element at a time.
Since `c` has arrays `a` and `b` as its elements, it will apply sum to individual arrays during `np.sum(x for x in c)`.
np.sum() sums up all the elements of c after flattening them.
Upvotes: 0 <issue_comment>username_2: The reason why you have the difference is that you are iterating an array of arrays instead of separate elements in the first case. I guess the rational explanation is that `numpy` doesn't know in advance what is yielded from generator and sums each element separately. And, the later statement treats your array of arrays as matrix and sums all its elements by default because they all are known in advance.
You can achieve the same result with:
```
assert np.sum(c, axis=0).tolist() == [4, 6]
```
Otherwise, you can try:
```
from itertools import chain
assert np.sum(list(chain(*c))) == 10
```
Upvotes: 0 <issue_comment>username_3: In numpy 1.13.3, `numpy.sum()` uses Python's build-in `sum()` to sum up the elements of a generator one by one. For array-likes (e.g., lists and arrays), numpy's vectorized implementation of `sum()` (which by default flattens the array-like and sums up its elements) is used.
My guess about the rational: The idea behind generators is that the elements are taken and *processed one by one.* The idea behind vectorization is that all data is ideally taken at once and *processed in parallel.* So, the ideas are complete opposites of each other.
Now, if a user explicitly provides a generator as an argument to `numpy.sum()` thent she explicitly wants the generated elements (vectors [1, 2] and [3, 4] in your example) to be summed up one by one and, therefore, do not wants the vectorization.
If a user provides an array-like as an argument to `numpy.sum()` then it is assumed that she wants the vectorized version of `sum()` to be applied. The questions is only what the primitive elements of the array-like that should be summed up are. By default, the array-like is flattened and the values of the flattened array-like (1, 2, 3, and 4 in your example) are summed up. This behavior can be changed using the `axis` parameter.
That is why generators are processed differently from arrays.

```
>>> np.sum(x for x in c)
array([4, 6])
```
is equivalent to summing over the fist dimension:
```
>>> np.sum(c, axis=0)
array([4, 6])
```
On the other hand, his will sum over all dimensions:
```
>>> np.sum(c)
10
```
Relevant part of the documentation:

> `np.sum(a, axis=None, ...`
>
>
> Sum of array elements over a given axis.
> `axis=None`, will sum all of the elements of the input array.

2018/03/20 | 561 | 1,542 | <issue_start>username_0: I use `keychain` to manage `ssh-agent`, and I add it into my `.zshrc`.
I have a ssh key with passphrase.
With the normal terminal, I can use `ssh` without call a `passphrase`.
But in tmux, it will ask me to input a passphrase for my ssh-key.
These are run in normal terminal.
```
➜ ~ echo $SSH_AGENT_PID; echo $SSH_AUTH_SOCK
14112
/<KEY>ssh-
lyHqTWPT02HF/agent.14111
```
If running `ssh my.server.domin`, it can connect directly.
I run `tmux` in the same terminal and then
```
➜ ~ echo $SSH_AGENT_PID; echo $SSH_AUTH_SOCK
14112
/<KEY>ssh-ly<KEY>agent.14111
```
If running `ssh my.server.domin`, it will ask me to input passphrase.<issue_comment>username_1: I find that I have a `alias` with ssh. `alias ssh=ssh-ident`.

2018/03/20 | 1,030 | 3,792 | <issue_start>username_0: I have a QPushButton and when I click the button I will call a method that take two parameters, in this example: `exampleMethod(int i, double d)`.
Now I connect the click event from QPushButton `button` to the exampleMethod like this:
`connect(button, &QPushButton::clicked,this, &Example::exampleMethod);`
But this doesn't work because the parameter of `clicked()` and `exampleMethod(int, double)` are not compatible.
Now I created a extra signal: `exampleSignal(int i, double d)` to connect to my slot:
`connect(this, &Example::exampleSignal, this, &Example::exampleMethod);`
And a additional slot with no parameters: `exampleMethodToCallFromButtonClick()` to call it from QPushButton clicked() in which I call the signal:
```
Example::Example(QWidget *parent) : QWidget(parent){
button = new QPushButton("Click", this);
connect(button, &QPushButton::clicked,this, &Example::exampleMethodToCallFromButtonClick);
connect(this, &Example::exampleSignal, this, &Example::exampleMethod);
}
void Example::exampleMethod(int i, double d){
qDebug() << "ExampleMethod: " << i << " / " << d;
}
void Example::exampleMethodToCallFromButtonClick(){
emit exampleSignal(5,3.6);
}
```
This works fine.
1) Now my first question: Is this realy the best way to do this **without lambda**?
With lambda it looks even nicer and I don't need two connect statements:
`connect(button, &QPushButton::clicked, [this]{exampleMethod(5, 3.6);});`
2) My second question: **with lamba** is this the best way to do this or are there any better ways to solve it?
I also considered to save the parameters from `exampleMethod` as a member variable, call the method without parameter and get instead of the parameters the member variables but I think thats not a so good way.
Thanks for your help!<issue_comment>username_1: I wouldn't do either of those things. Receive the signal, gather your parameters and then just call `exampleMethod`. A lambda is more appropriate when the parameters are known at the point where you connect.
```
Example::Example(QWidget *parent) : QWidget(parent){
button = new QPushButton("Click", this);
connect(button, &QPushButton::clicked, this, &Example::onButtonClicked);
}
void Example::exampleMethod(int i, double d){
qDebug() << "ExampleMethod: " << i << " / " << d;
}
void Example::onButtonClicked(){
int i = ...;
double d = ...;
exampleMethod(i, d);
}

```
int Example::iValue() const {
...
}
double Example::dValue() const {
...
}
```
Then, the following are equivalent:
```
connect(..., this, [this]{ exampleMethod(iValue(), dValue()); });
connect(..., this, std::bind(&Example::exampleMethod, this, iValue(), dValue()));
```
The choice between `onButtonClicked()` and the use of `iValue()` and `dValue()` is determined mostly by whether the values are useful when factored out separately, and whether for code comprehension it makes sense to specify the call at the `connect` site, or move it out to an individual method.
Finally, if you do use [the single-method approach](https://stackoverflow.com/a/49384062/1329652), and the button is instantiated with `setupUi`, i.e. you've designed `Example` in Designer, you can save the `connect` call by naming the handler method appropriately:
```
Q_SLOT void Example::on_button_clicked();
```
The `button` here is the name of the button object in the .ui file. The connection will be made automatically by `Ui::Example::setupUi(QWidget*)`.

Upvotes: 3 [selected_answer]<issue_comment>username_2: **Apple** provides support for some of the default `UIActivityTypes` that includes both `Facebook` and `Twitter` as required by you.
You can get a complete list of `UIActivityTypes` here: <https://developer.apple.com/documentation/uikit/uiactivitytype>
By default, all the `UIActivityTypes` appear in the `UIActivityController`. The activities you don't want to appear in the `UIActivityController` an be added in the `exclude list`, i.e
```
activityViewController.excludedActivityTypes = [.postToFlickr, .postToVimeo]
```
Also, whenever an `App` that includes a **`Share App Extension`** is installed on the device, it is also added to the `UIActivityController`.
***Example*:**
**WhatsApp**. Whenever you install WhatsApp on your device, it will appear as a `Share App Extension` in the `UIActivityController`.
You cannot remove them but can only hide them from the `UIActivityController's` **More** option.
Let me know if you still face any issues.

You can use:
```
Array.prototype.push.apply(arr1,arr2);
console.log(arr1); // final merged result will be in arr1
```
Hope it helps
To delete, you can use:
```
array.splice(index, 1);
```
Check splice reference for more details.

Any suggestions why this happens?<issue_comment>username_1: cmd\_table is declared in test.c file and you are using it in use.c file. As scope of cmd\_table is limited to test.c file you can not use it in use.c file
Upvotes: 1 <issue_comment>username_2: `cmd_table` is defined in `test.c`. If you want it to be visible to the compiler when it is compiling other C files, there needs to be an `extern` declaration visible when it is compiling the other files. The usual way to do this is to put the `extern` declaration in the header.
```
// in test.h
extern fun_desc_t cmd_table[];
```
Unfortunately, that won't tell you how big the array is. For lookup tables, like this, a common way to solve this problem is to put a null sentinel value at the end.
```
fun_desc_t cmd_table[] = {
{cmd_help, "?", "show this help menu"},
{cmd_exit, "exit", "exit the command shell"},
{cmd_pwd, "pwd", "print working directory"},
{cmd_cd, "cd", "change directory"},
{NULL, NULL, NULL}
};
```
And you change the loop in `main` as follows
```
int main()
{
for(int i = 0; cmd_table[i].fun != NULL; i++)
{
// Do whatever
}
return 0;

I have read that since wildfly 8 such encoding is possible with gzip filter, I have tried to add filter to Wildfly config similar to one described here: <https://rumianom.pl/rumianom/entry/gzip_content_encoding_in_wildfly>, however, with no success. I tried many pradicates like `equals[%{i,Accepted-Encoding},\"gzip\"]` (I found similar example in undertow unit tests) or `regex[pattern='(?:gzip)(;.*)?', value=%{o,Accept-Encoding}, full-match=false]`. Sadly none of my solutions worked.<issue_comment>username_1: This or a variation thereof should in fact work (using Wfly10 and have been doing so for a long time):
```
```
You need to define then reference/configure the filters, in your case, at least the gzipFilter.
Upvotes: 2 <issue_comment>username_2: Filter with pattern worked. If your pattern has special characters like . you need to escape them.
Note that I did not find any documentation regarding what "i" and "o" values in value= are. It appears that if "o" is given pattern searches header in output from app (response) and if "i" is given it matches input message (request).

2018/03/20 | 848 | 2,495 | <issue_start>username_0: I have an array like this :
`array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");`
and would like to get only my values, for example here :
simpleTab=`array("35","37","43");`
or otherwise like this, it should be better for me to get a list :
```
simpleList=["35";"37";"43"]
```
I'm creating a function because I'll need it several times so here it is :
```
$simpleArray=array(); //don't know if this should be array, i'd like to have a list
foreach($valueAssoc as $key => $value{//array_push($simpleArray,$value);//NO it returns an array with keys 0 , 1 , etc
//$simpleArray[]=$value; //same ! I don't want any keys
//I want only an array without any index or key "tableau indexé sans clef"
echo $value;
//would like to have some method like this :
$simpleArray.add($value);//to add value in my list -> can't find the php method
```<issue_comment>username_1: You're looking for [array\_values](http://php.net/manual/en/function.array-values.php) which will return just the values from the key/value pairs.
```
$arr = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");
$arrVals = array_values($arr);
```
The code behind it is much the same as you'd expect, with a `foreach` looping through and pushing the result to a new array.
Upvotes: 3 <issue_comment>username_2: No need to create a function for it, there is an inbuilt function [`array_values()`](http://php.net/manual/en/function.array-values.php) that does exactly same as required.
From the docs:
>
> Return all the values of an array
>
>
>
Example:
```
$arr = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");
print_r(array_values($arr)); // Array ( [0] => 35 [1] => 37 [2] => 43 )
```
Upvotes: 3 <issue_comment>username_3: Try this -
```
$arrs = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");
$array = (array_values($arrs));
echo "
```
";
print_r($array);
```
```
Upvotes: 2 <issue_comment>username_4: If you want the without Key You should use `array_values()` and `json_encode()`(It means convert to string) the array like
```
$arr = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");
print_r(json_encode(array_values($arr)));
```
OutPut:
```
["35","37","43"]
```
Upvotes: 4 <issue_comment>username_5: Try this guys...
```
$Data_array = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");
$output_array = array();
foreach($Data_array as $a)
{
array_push($output_array,$a->{$key_name});
}
// Output will be :
$output_array : ["35","37","43"]

For simple testing I've the following docker file:
```
FROM microsoft/powershell:latest
RUN mkdir -p /tmp/powershell
COPY C:/temp/somedirectory /tmp/powershell
```
I want to copy the files included in C:\temp\somedirectory to the docker linux container. When building the image I get the following error:

Of course I know that Docker says that I can't find the file/directory. Therefore I also tried `C:/temp/somedirectory/.`, `C:/temp/somedirectory/*`, and `C:\\temp\\somedirectory\\` as alternativ source paths in the Dockerfile -> Result: none of them worked.

How can I copy a folder including subfolder and files via a Dockerfile?<issue_comment>username_1: You cannot copy files that are outside the build context when building a docker image. The build context is the path you specify to the docker build command. In the case of the instruction
```
C:\temp\docker_posh> docker build --rm -f Dockerfile -t docker_posh:latest .
```
The `.` specifies that the build context is `C:\temp\docker_posh`. Thus `C:/temp/somedirectory` cannot be accessed. You can either move the Dockerfile to temp, or run the same build command
under `C:\temp`. But remember to fix the Dockerfile instructions to make the path relative to the build context.
Upvotes: 5 [selected_answer]<issue_comment>username_2: If you want to copy something from host machine to running docker container then you can use `docker cp` command like:
```
docker cp [OPTIONS] CONTAINER_NAME:CONTAINER_SRC_PATH DEST_PATH
docker cp [OPTIONS] SRC_PATH CONTAINER_NAME:CONTAINER_DEST_PATH
```
Options:
```
--archive -a Archive mode (copy all uid/gid information)
--follow-link -L Always follow symbol link in SRC_PATH
```
If you don't want to use options you can ignore them.
Upvotes: 1 <issue_comment>username_3: I found this "feature" very inconvenient and just wrote my own build script that copies everything I cared about into a new temp folder, then builds the docker image in the proper context. Here's a Powershell script for anyone that finds this approach helpful.
Folder structure (feel free to change) looks like this for me:
```
lib\somefile1.ps1
lib\somefile2.ps1
dockerfolder\Dockerfile
dockerfolder\mybuilderscript.ps1
my-main-file.ps1
```
Here's the script:
```
# Docker Image Tag Name
$tagname = "myimage"
# Generate temp directory
$parent = [System.IO.Path]::GetTempPath()
[string] $name = [System.Guid]::NewGuid()
$dockerBuildDirectory = New-Item -ItemType Directory -Path (Join-Path $parent $name)
# Copy things we care about from the parent repo into our build dir
# Copy source folder that has our Dockerfile (and this script) into a folder called "dockerworking" in the temp build directory
Copy-Item -Recurse "../dockerfolder" $dockerBuildDirectory/dockerworking
# Copy directories above our current folder into the dockerworking directory
Copy-Item -Recurse "../lib" $dockerBuildDirectory/dockerworking
# Copy the main script into the working directory
Copy-Item -Recurse "../my-main-file.ps1" $dockerBuildDirectory/dockerworking
# Let the user know where these files are for any troubleshooting that comes up
Write-Host -ForegroundColor Green "Docker files stage at $dockerBuildDirectory"
# Create the docker image in the "dockerworking" folder where everything resides
docker build --no-cache --tag $tagname $dockerBuildDirectory/dockerworking
```
The Dockerfile has "local" COPY commands (and all the files are pre-staged to the right location) so Docker is happy.
Dockerfile snippet:
```
FROM mcr.microsoft.com/windows/servercore:ltsc2019
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]
RUN New-Item -Type Directory -Path "c:\scripts" | Out-Null
COPY "lib" "c:\scripts"
COPY "my-main-file.ps1" "c:\scripts"
ENTRYPOINT ["powershell", "-NoProfile", "-Command", "c:\\scripts\\my-main-file.ps1"]

Upvotes: 0 <issue_comment>username_3: For me, none of these worked. I have AdGuard installed and had to perform the following (Running on Windows 11):
* Exclude Atom app from filtering by entering the full Atom app path in AdGuard > General Settings > Advanced Settings.
* + App Path is generally: "C:\Users\USER\_NAME\AppData\Local\atom\atom.exe"
* Also, you need to add " atom.io " to the HTTPS Exclusions list. (Settings -> Network -> HTTPS filtering -> Exclustions -> + add atom.io -> Then click save).
This made it work for me with no other configuration changes. If you do not have AdGuard or other application of this type installed, then there may be other anti-virus/Anti-malware applications you may need to exclude this app from.

2018/03/20 | 1,491 | 3,542 | <issue_start>username_0: The data frame looks like this (the dots are supposed to be vertical dots):
```
Class IncreasingNumber
"A" 3 <- row 1
"A" 5 <- row 2
... ...
"A" 20 <-row 31
"B" 1
"B" 2
... ...
"B" 41 <- row 63
"C" 1
......
```
There are 20 different classes. The number of rows within each class equals 31.
What I wan to do is quite simple. For each class, I want to insert 3 new rows between all rows. So, we want to insert 3 new rows between row 1 and row 2, and yet 3 others in between row 2 and row 3, all the way up to 3 three new rows between row 30 and 31. But NO new rows between row 31 and 32, since these belong to a different class.
We want to do this for every class.
The three rows which we insert has the same Class as its surrounding rows, and the IncreasingNumber value for those three rows are just the 3 equally spaced points within the IncreasingNumber values for the surrounding points.
For example, for the first class, and for the first three rows to be inserted between row 1 and row 2, we see that the IncreasingNumbers are 3 and 5.
Therefore, the first value for the first row that we insert should be 3.5. The next value should be 4. The third value should be 4.5.
So we should get something like this for the first two classes:
```
Class IncreasingNumber
"A" 3
"A" 3.5 <- new row
"A" 4 <- new row
"A" 4.5 <- new row
"A" 5
... ...
"A" 20
"B" 1
"B" 1.25 <- new row
"B" 1.5 <- new row
"B" 1.75 <- new row
"B" 2
... ...
"B" 41
"C" 1

2018/03/20 | 1,137 | 4,324 | <issue_start>username_0: I have two Activities, I am adding data to Firestore from these two activities individually. But, whenever I add second activity data to Firestore, it is overwriting the first activity data. I used below code in the two activities:
```
firebaseFirestore.collection("Users").document(user_id).set(data)
```
How to stop overwriting? I want to save both Activities data in the same `user_id`.<issue_comment>username_1: I suggest you to add one more document or collection that it will be able to store more just one data values for single user.
You can create a document references for both activities:
```
firebaseFirestore.collection("Users").document(user_id+"/acitivity1").set(data);
//and
firebaseFirestore.collection("Users").document(user_id+"/acitivity2").set(data);
```
Or you can create a sub-collection for it:
```
firebaseFirestore.collection("Users").document(user_id)
.collection("Activities").document("acitivity1").set(data);
//and
firebaseFirestore.collection("Users").document(user_id)
.collection("Activities").document("acitivity2").set(data);
```
More about hierarchical data [there](https://firebase.google.com/docs/firestore/data-model#hierarchical-data).
Upvotes: 4 [selected_answer]<issue_comment>username_2: If you know that the user document allready exists in firestore then you should use
```
firebaseFirestore.collection("Users").document(user_id).update(data)
```
If you don't know if the document exists then you can use
```
firebaseFirestore.collection("Users").document(user_id).set(data, {merge:true})
```
This performs a deep merge of the data
Alternatively you can do it by using subcollections
Upvotes: 2 <issue_comment>username_3: There are two ways in which you can achieve this. First one would be to use a `Map`:
```
Map map = new HashMap<>();
map.put("yourProperty", "yourValue");
firebaseFirestore.collection("Users").document(user\_id).update(map);
```
As you can see, I have used `update()` method instead of `set()` method.
The second approach would be to use an object of your model class like this:
```
YourModelClass yourModelClass = new YourModelClass();
yourModelClass.setProperty("yourValue");
firebaseFirestore.collection("Users").document(user_id)
.set(yourModelClass, SetOptions.mergeFields("yourProperty"));
```
As you can see, I have used the `set()` method but I have passed as the second argument `SetOptions.mergeFields("yourProperty")`, which means that we do an update only on a specific field.
Upvotes: 3 <issue_comment>username_4: As per the documentation, you could use as a second parameter `{merge:true}`, in my experience the problem usually is in the fact that you are trying to store different data but with the same key.
Even using `{merge: true}` will always update the current key with the value you are passing in.
Merge:true Works only if the key does not exist already. I believe every key in a document must be unique.
To test it try to pass(keeping `{merge: true}` as the second parameter) data with a different key, it will merge to existing.
Upvotes: 2 <issue_comment>username_5: Try this for a direct update
`db.collection('cities').doc('restaurants').update({
rating:"3.2"
});`
Only the field rating is going to change, the rest of the fields will remain the same.
Lets say you have 3 fields, and want to change only 2 of them, you can also do this in a different way
```
// You get the document 'restaurants' and then do the below
db.collection('cities').doc('restaurants').get().then((doc) => {
// Get the rating field string, parse it to a float, remove 0.4 from it and
// set it to a tmp variable
var tmpRating = parseFloat(doc.data()['rating']) - 0.4;
// Get the array of strings field 'menu' and set it to a tmp variable
var tmpMenu = doc.data()['menu'];
// Push 'spaghetti' string to the tmp array of strings( Can also put an
// adapting string variable instead of a specific string like 'spaghetti'
tmpMenu.push('spaghetti');
// Update only the specific fields 'rating' and 'menu' and keep the rest unchanged.
db.collection('cities').doc(doc.id).update({
rating: toString(tmpRating), // Don't forget to separate them by commas
menu: tmpMenu
});
});

2018/03/20 | 829 | 3,611 | <issue_start>username_0: I am trying to bind a TextBlock to items in a ObservableCollection. TextBlock values should be generated up to elements from collection. Count of elements in collection is between 0 and 7 (if it helps). MyClass implemented INotifyPropertyChanged. It should be directly TextBlock, not ListBox. How can I do it? Thanks!
Update: The problem is that I don't know previously the number of elements in collection. I know that it is better to use ListBox or ListView in this case, but it's important to make it in TextBlock or Label
For example:

```
public class StringsCollectionConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (value == null) return null;
return string.Join("\n", value as ObservableCollection);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
```

The problem is to get value updated on collection changed(here I mean not setting Values to new collection, but adding/removing items to/from the collection).
To implement updating on add/remove you have to use `MultiBinding` with one of bindings to the ObservableCollection.Count, so if the count be changed, then the bound property will be updated.
```
public class MultValConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
if (values.Length > 1 && values[0] is ICollection myCol)
{
var retVal = string.Empty;
var firstelem = true;
foreach (var item in myCol)
{
retVal += $"{(firstelem?string.Empty:", ")}{item}";
firstelem = false;
}
return retVal;
}
else
return Binding.DoNothing;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
throw new NotImplementedException("It's a one way converter.");
}
}
```

```
public class Vm
{
public Vm()
{
// new collection assigned via property because property setter adds event handler
Values = new ObservableCollection();
}
ObservableCollection values;
public ObservableCollection Values
{
get => values;
set
{
if (values != null) values.CollectionChanged -= CollectionChangedHandler;
values = value;
if (values != null) values.CollectionChanged += CollectionChangedHandler;
OnPropertyChanged();
}
}
private void CollectionChangedHandler(object sender, NotifyCollectionChangedEventArgs e)
{
OnPropertyChanged("ValuesText");
}
public string ValuesText
{
get { return "Values: " + String.Join(", ", values);}
}
}
```
and then bind to that property:

2018/03/20 | 715 | 2,705 | <issue_start>username_0: (Taking first steps with web development but it appears that I'm currently unable to use even the most fundamental tools, like e.g. a browser debugger.)
When I init a new vue.js 2.x project as follows...
```
sudo npm install --global vue-cli
vue init simple vue1
```
(accepting defaults for all prompts)
... and then proceed to open the generated index.html in Chromium, I more or less see what I would expect in the browser debugger. More specifically, I can enter the following in the browser console...
```
this.app.$data.greeting = "Blah"
```
... and see the page greeting change immediately, as I would expect.
However, when I use a webpack template...
```
vue init webpack-simple vue2
cd vue2
npm install
npm run dev
```
... I'm unable to find the data in the browser console. From the code in App.vue I would expect that there should be a `msg` or `data` property somewhere, but I get lost pretty quickly when I try to look for it. I do find `.msg` in the served build.js but the code is so obfuscated that I fail to determine the full path to it. I'd probably be able to find it if I invested a lot more time but somehow I feel that it cannot be that complicated and that I must be missing something.
So, how would one go about finding this methodically?<issue_comment>username_1: Using the [Vue DevTools](https://github.com/vuejs/vue-devtools) is your best bet. When you are running Vue through webpack, `this` will be the `window` object, not the Vue instance.
(Technically, you can also do `window.Vue = new Vue({ })` or `var foobar = new Vue({}); window.Vue = foobar` and then access Vue properties at `window.Vue.$data.greeting` or whatever but the devtools are designed for this functionality and will be a lot easier for you)

```
var app = new Vue({
el: '#app',
...
})
```
With the "webpack-simple" template, the `vue-loader` loader wraps the components in a CommonJS module (which are closures and therefore prevent variables to be directly accessible outside the module).
To remediate this issue for debugging purpose, you can use [Vue devtools](https://github.com/vuejs/vue-devtools).
Eventually you can also make your app variable accessible in dev environment.
Define a `DEV` variable in webpack.config.js (remove it for production):
```
plugins: [
new webpack.DefinePlugin({
DEV: true
})
]
```
And expose what you want in your code :
```
if (typeof DEV !== 'undefined' && DEV) {
window.app = app; //this block will be removed by the build step
}
```

2018/03/20 | 1,671 | 6,380 | <issue_start>username_0: Very related to this question ([How can I prevent my Google App Engine cron jobs from burning through all my instance hours?](https://stackoverflow.com/questions/8670532/how-can-i-prevent-my-google-app-engine-cron-jobs-from-burning-through-all-my-ins?answertab=votes#tab-top)), yet unfortunatly I not only experience something similar, in my Cron-jobs in Appengine multiple instances are created, which causes quite a high number of Instance hours to be billed.
I tried different intervals to determine whether this has an effect on the instance hours, but cannot determine the difference currently. To illustrate, I got billed App Engine Frontend Instances: 263.462 hours for the following three cron-jobs (in just 10 days!):
```
cron:
- description: Push a weather "tick" onto pubsub every 5 minutes
url: /publish/weather-tick
schedule: every 5 minutes
- description: Push a crypto "tick" onto pubsub every 5 minutes
url: /publish/crypto-tick
schedule: every 5 minutes
- description: Push a astronomy "tick" onto pubsub every 6 hours starting at 00:00
url: /publish/astronomy-tick
schedule: every 6 hours synchronized
```
When I changed this to one cron-job for each minute:
```
cron:
- description: Push a "tick" onto pubsub every 1 minutes
url: /publish/minute-tick
schedule: every 1 minutes
```
I currently still get multiple instances, see:
[](https://i.stack.imgur.com/uAooY.png)
*Strangely enough, the instance went from 2 --> 3 upon changing to just one cron-job every minute.*
I also have difficulties understanding why there are 3 instances 'created', whilst 0 are 'running', and billing estimates are 1.
Contact with Google could point me towards the high number of instances (which caused the high number of Instance hours), and my parameters set on 'automatic sclaing', which allows for this. However, changing it to manual limits the amount of free instance hours (from 28 to I believe 9).
**My Situation**
I am running cron-jobs to invoke Pub/Sub events. I have Google Cloud functions that listen to Pub/Sub events so that I can execute database updates based on these ticks. This is folllwing the tutorial provided on [Google Firebase](https://firebase.googleblog.com/2017/03/how-to-schedule-cron-jobs-with-cloud.html?utm_campaign=culture_education_functions_en_06-29-17&utm_source=Firebase&utm_medium=yt-desc "here"). I understand the billing of 15 minutes of an instance, even though it's lifespan is shorter, however I cannot understand how or why multiple are created if only such a small task is executed. I am especially intregued, as in the related question ([How can I prevent my Google App Engine cron jobs from burning through all my instance hours?](https://stackoverflow.com/questions/8670532/how-can-i-prevent-my-google-app-engine-cron-jobs-from-burning-through-all-my-ins?answertab=votes#tab-top)), that person is experiencing 24 hours, but expectedly just with one instance. Why am I getting 3? I feel I am missing some conceptual understanding of this process, and the tools to adjust accordingly. Any help or pointers would be very welcome!<issue_comment>username_1: Ok, so as often - anoyingly but helpful - is, explaining it to someone else helps thinking about this problem. I hope this anwser might be useful for someone else having the same questions.
I stumbled upon [this Google Groups](https://groups.google.com/forum/#!topic/google-appengine/eJUQ7NlNkso "this Google Groups") discussion, which talks about how instances of 'older' versions are kept running due to the Flexible Environment, or even when scaling is set to manual. Quite recent comments indicate that this is a roll-back issue from Google's side. Apparently (I was unaware of this), you can delete or stop the older versions and thereby stop the running instances. A related Stack Overflow question and awnser can be found here: [How to automatically delete old Google App Engine version instances?](https://stackoverflow.com/questions/34499875/how-to-automatically-delete-old-google-app-engine-version-instances). This also discusses how to ensure automatic instance deletion from older versions (and is probably the correct way to go). Doing it manually: go to your Appengine dashboard, click versions in the left menu, and select and delete the older versions (if not needed anymore ofcourse). [This named Google Groups](https://groups.google.com/forum/#!topic/google-appengine/eJUQ7NlNkso "this Google Groups") discussion also shows how.
The result:
[](https://i.stack.imgur.com/Y2u16.png)
Also, not that there is a version selection in the top left. I could select the older and latest one (instead of 'all'), which showed me the idle running older instances. This is an additional indication of the 'issue' being the old versions, rather than this one. Learning everyday!

The dynamic scheduler may, depending on the scaling config and your app's response time, decide that it needs to spawn additional instances to handle such traffic peaks. You could try to tweak your scaling config to prevent that, see [max\_num\_instances for Google App Engine Standard Environment](https://stackoverflow.com/questions/48380505/max-num-instances-for-google-app-engine-standard-environment/48387012#48387012)
Another way to avoid this would be to stagger your requests to smooth the traffic pattern a bit:
* use a single cron entry for the overlapping schedules and inside its handler make a separate request for each job you want to run, possibly staggered in time a bit. For example using delayed push queues tasks, see [do google app engine pull queues return tasks in FIFO order?](https://stackoverflow.com/questions/40475174/do-google-app-engine-pull-queues-return-tasks-in-fifo-order/40478036#40478036)
* use explicit cron schedule times to minimize the overlap, say schedule one at minutes 1, 6, 11, etc and another one at minutes 2, 7, 12, etc. You only have a limited number of possible combinations, though.

2018/03/20 | 492 | 1,814 | <issue_start>username_0: With the arrival of the display of emoticons in Google searches, I wanted to make my own tests by embellishing a few meta\_title to see if it could have a positive effect for our site.
Unfortunately, after saving my meta\_title change with the special character, no get no error message but the field is now empty on both prestashop and the database.
And for good reason, the encoding in the database in utf8 instead of utf8mb4.
So I modified the encoding of the column as well as the table for which I wanted to have access to the special characters but they are transformed after "???".
It seems that I would have to change the encoding of the database itself and that's my question:
**Do you know if there is any contraindication to switch the prestashop database from utf8 to utf8mb4?**
I'm afraid there may be a loss of data somewhere in the database.
I am interested in all the information on the subject.
Thank you in advance.<issue_comment>username_1: I've been through a migration, it did not alter any kind of field or any kind of character (it was a Wordpress, with emojies), it's just a charset extension I guess.

If you are getting question marks out of the database, then the data is lost -- it was lost when trying to insert, for example, a 4-byte Emoji into the 3-byte `CHARACTER SET utf8`.

2018/03/20 | 353 | 1,312 | <issue_start>username_0: Sometimes in asp.net, the Control.ClientID returns the whole Control object instead of the ClientID string. I haven't paid too much attention to it up until now as I could just fish it out client side with ClientID.Id. But now I need to pass the ID of an iframe and IE won't let me pass the iframe object so I have to get the string of the ID this time.
The iframe:
```
```
The Codebehind:
```
YouTubeScript.Text = @"
$(function() {
" + Helpers.CallJavascriptFunction("InitYoutubeVideo", VideoFrame.ClientID) + @"
});
";
```
**Update/Answer**
I need to wrap `VideoFrame.ClientID` in quotation marks so that javascript/jquery recognises it as a string. Otherwise it sees the id and converts it into the html object belonging to that id.<issue_comment>username_1: It looks like you are trying to mix javascript and inline aspnet code somehow. it should look like this:
```
Helpers.CallJavascriptFunction("InitYoutubeVideo", "<%= VideoFrame.ClientID %>");
```
Upvotes: 1 <issue_comment>username_2: You have two options. Use the client ID properly:
```
$(document).ready(function() {
InitYoutubeVideo('<%=VideoFrame.ClientID%>');
});
```
Or make the client id static:
```
$(document).ready(function() {
InitYoutubeVideo('VideoFrame');
});

2018/03/20 | 2,251 | 7,653 | <issue_start>username_0: I am working on integration tests of .NET Core application and want to use some test configuration. My configuration is a POCO class that is configured via `appsettings.json` and then consumed via `IOptions`. In my tests I'd like to use an instance of that class.
Here is the code:
```
var mySettings = GetTestSettings(); // factory method returning POCO class
var configurationBuilder = new ConfigurationBuilder();
// I am looking for something like
configurationBuilder.AddInMemoryObject("Settings", mySettings);
// does not work, result is just string
configurationBuilder.AddInMemoryCollection("Settings",
JsonConvert.SerializeObject(mySettings));
// requires filename
configurationBuilder.AddJsonFile("filename.json");
```
What is the easiest way to feed POCO to configuration?<issue_comment>username_1: `AddInMemoryCollection` takes a collection of `KeyValuePair` where a key is setting key and value is its value. This call from the question
```
configurationBuilder.AddInMemoryCollection("Settings", JsonConvert.SerializeObject(mySettings));
```
actually passes "Settings" as a key and whole JSON as one setting value, which expectedly does not work.
But the overall approach is correct, you should use `AddInMemoryCollection` extension call. In collection passed to this call, setting keys are full paths within configuration, delimited by a colon. Say if you have following settings POCO:
```
public class SomeSettings
{
public string SomeKey1 { get; set; }
public int SomeKey2 { get; set; }
}
```
and it's loaded from following JSON
```
{
"SomeSettings": {
"SomeKey1": "SomeData",
"SomeKey2": 123
}
}
```
the keys would be `SomeSettings:SomeKey1` and `SomeSettings:SomeKey2`.
You could then add such configuration with following `AddInMemoryCollection` call:
```
configurationBuilder.AddInMemoryCollection(new Dictionary
{
{ "SomeSettings:SomeKey1", "SomeData" },
{ "SomeSettings:SomeKey2", 123 },
});
```
Now, if you want to add settings POCO with one call, you could write simple extension method that will enumerate setting class properties using reflection and return collection of key-value pairs for properties names and values.
Here is a sample:
```
public static class ObjectExtensions
{
public static IEnumerable> ToKeyValuePairs(this Object settings, string settingsRoot)
{
foreach (var property in settings.GetType().GetProperties())
{
yield return new KeyValuePair($"{settingsRoot}:{property.Name}", property.GetValue(settings).ToString());
}
}
}
public static class ConfigurationBuilderExtensions
{
public static void AddInMemoryObject(this ConfigurationBuilder configurationBuilder, object settings, string settingsRoot)
{
configurationBuilder.AddInMemoryCollection(settings.ToKeyValuePairs(settingsRoot));
}
}
```
In the test:
```
var configurationBuilder = new ConfigurationBuilder();
var mySettings = GetTestSettings();
configurationBuilder.AddInMemoryObject(mySettings, "Settings");
```
Such simple `ObjectExtensions.ToKeyValuePairs` extension method will work for plain POCO like `SomeSettings` above. However it will not work if some of the properties are also objects like here:
```
public class InnerSettings
{
public string SomeKey { get; set; }
}
public class OuterSettings
{
public InnerSettings InnerSettings { get; set; }
}
```
However I believe you got an idea and could make required adjustments if required.

2018/03/20 | 2,328 | 7,668 | <issue_start>username_0: I Have a dataframe named `mydata`. Here's a sample of the relevant column:
```
Accuracy.Percentage
100.00
127.00
60.00
175.00
52.00
```
Now, what I want to accomplish is the following: when the value of a row is < 100, I want change its value with `100 - mydata$Accuracy.Percentage`, when the value is > 100, I want to change its value with `mydata$Accuracy.Percentage - 100`. I have tried something like
```
result <- if(mydata$Accuracy.Percentage < 100) {
mutate(result$Accuracy.Percentage = 100 - result$Accuracy.Percentage)
}
else mutate(result$Accuracy.Percentage = result$Accuracy.Percentage - 100)
```
But I can't seem to get it to work, although there probably is a simple way to accomplish this. Thanks in advance, I hope I have been clear enough and formulated my question in a understandable manner!<issue_comment>username_1: `AddInMemoryCollection` takes a collection of `KeyValuePair` where a key is setting key and value is its value. This call from the question
```
configurationBuilder.AddInMemoryCollection("Settings", JsonConvert.SerializeObject(mySettings));
```
actually passes "Settings" as a key and whole JSON as one setting value, which expectedly does not work.
But the overall approach is correct, you should use `AddInMemoryCollection` extension call. In collection passed to this call, setting keys are full paths within configuration, delimited by a colon. Say if you have following settings POCO:
```
public class SomeSettings
{
public string SomeKey1 { get; set; }
public int SomeKey2 { get; set; }
}
```
and it's loaded from following JSON
```
{
"SomeSettings": {
"SomeKey1": "SomeData",
"SomeKey2": 123
}
}
```
the keys would be `SomeSettings:SomeKey1` and `SomeSettings:SomeKey2`.
You could then add such configuration with following `AddInMemoryCollection` call:
```
configurationBuilder.AddInMemoryCollection(new Dictionary
{
{ "SomeSettings:SomeKey1", "SomeData" },
{ "SomeSettings:SomeKey2", 123 },
});
```
Now, if you want to add settings POCO with one call, you could write simple extension method that will enumerate setting class properties using reflection and return collection of key-value pairs for properties names and values.
Here is a sample:
```
public static class ObjectExtensions
{
public static IEnumerable> ToKeyValuePairs(this Object settings, string settingsRoot)
{
foreach (var property in settings.GetType().GetProperties())
{
yield return new KeyValuePair($"{settingsRoot}:{property.Name}", property.GetValue(settings).ToString());
}
}
}
public static class ConfigurationBuilderExtensions
{
public static void AddInMemoryObject(this ConfigurationBuilder configurationBuilder, object settings, string settingsRoot)
{
configurationBuilder.AddInMemoryCollection(settings.ToKeyValuePairs(settingsRoot));
}
}
```
In the test:
```
var configurationBuilder = new ConfigurationBuilder();
var mySettings = GetTestSettings();
configurationBuilder.AddInMemoryObject(mySettings, "Settings");
```
Such simple `ObjectExtensions.ToKeyValuePairs` extension method will work for plain POCO like `SomeSettings` above. However it will not work if some of the properties are also objects like here:
```
public class InnerSettings
{
public string SomeKey { get; set; }
}
public class OuterSettings
{
public InnerSettings InnerSettings { get; set; }
}
```
However I believe you got an idea and could make required adjustments if required.

```
configurationBuilder.AddInMemoryCollection(ToDictionary(GetTestSettings()));
private static IEnumerable> ToDictionary(object o) =>
AddPropsToDic(JObject.FromObject(o), new Dictionary(), "Settings");
private static Dictionary AddPropsToDic(JObject jo, Dictionary dic, string prefix)
{
jo.Properties()
.Aggregate(dic, (d, jt) =>
{
var value = jt.Value;
var key = $"{prefix}:{jt.Name}";
if (value.HasValues)
return AddPropsToDic((JObject) jt.Value, dic, key);
dic.Add(key, value.ToString());
return dic;
});
return dic;
}
```

```
dotnet add package Extensions.Configuration.Object
```
And then you can do:
```cs
var configuration = new ConfigurationBuilder()
.AddObject(new // This supports anonymous and simple classes.
{
MyProperty = "MyValue",
MySection = new
{
MyOtherProperty = "MyOtherValue"
}
})
.Build();
```
If you don't want an additional dependency, you can just copy source code from [GitHub](https://github.com/lawrence-laz/Extensions.Configuration.Object).

[@Laurynas\_Lazauskas](https://stackoverflow.com/a/72242705/5963888) answer is actually the most correct and approached it by adding a Provider which is probably the best technical route to take. However if you are interested in a Quick and Dirty solution something like this could work, and its performance to @Laurynas\_Lazauskas answer might as well be equal. The only feature I wish I could see is the ability to add in a root key.

```
public static Dictionary CreateConfiguration(this TObject @object, string rootKey = "")
where TObject : class
{
if( @object == null) { throw new ArgumentNullException(nameof(@object)); }
var d = new Dictionary();

if (a==1 and b==1) or (a==0 and b==0):

Upvotes: 0 <issue_comment>username_2: This is a gross misuse of a list comprehension.
The logic you may wish to implement *can* be implemented via a ternary statement:
```
a, b = 1, 1
correct = 1 if ((a == 1 and b == 1) or (a == 0 and b == 0)) else 0
#1
```
However, even this is close to unreadable. There is nothing intrinsically wrong with ternary statements; so I would advise splitting your logic:
```
test1 = (a == 1) and (b == 1)
test2 = (a == 0) and (b == 0)
correct = 1 if (test1 or test2) else 0
```

Upvotes: 2 [selected_answer]<issue_comment>username_4: What you are doing is essentially "not xor", so, your whole logic can be replaced with
`int(not (a ^ b))`:
```
a,b = 0, 0
print(int(not (a ^ b)))
a, b = 1, 0
print(int(not (a ^ b)))
a, b = 0, 1
print(int(not (a ^ b)))
a, b = 1, 1
print(int(not (a ^ b)))
# 1
# 0
# 0
# 1
```
If you don't like the "magical" "not xor" you can explicitly validate the input against `(0, 0)` and `(1, 1)`:
```
print(1 if (a, b) in ((0, 0), (1, 1)) else 0)
```
This replaces the `if` condition only. If you do have a list of tuples then you would still need the `in` as other answers suggest:
```
def validate(a, b):
return int(not a ^ b)
li = [(0, 0), (0, 1), (1, 0), (1, 1)]
print([validate(a, b) for a, b in li])
# [1, 0, 0, 1]
```
or with `map`, but then `validate` will need to be changed to accept a tuple (and a call to `list` is needed if using Python 3 and wanted output should be a list):
```
def validate(tup):
return int(not tup[0] ^ tup[1])
li = [(0, 0), (0, 1), (1, 0), (1, 1)]
print(list(map(validate, li)))
# [1, 0, 0, 1]

```
correct = 1 if ((a == 1 and b == 1) or (a == 0 and b == 0)) else 0

if `a` and `b` represent a couple of values in a list of tuples, and you want a list back of one and zeroes, you can use list comprehension:

```
What you're really trying to do is quite unclear, but if you have two variables `a` and `b` and want to check if both are equal to `0` or both are equal to `1`, you don't need a list comprehension at all:
```
correct = 1 if (a == 0 and b == 0) or (a == 1 and b == 1) else 0
```
and since in Python, `Bool` is a subclass of `int` with `False == 0` and `True == 1`, this can be simplified to
```
correct = (a == 0 and b == 0) or (a == 1 and b == 1)
```
Using a list comprehension only makes sense if you actually have a list of pairs and want to test all those pairs, ie:
```
pairs = [(0, 0), (0, 1), (1, 0), (1, 1)]
corrects = [(a == 0 and b == 0) or (a == 1 and b == 1) for (a, b) in pairs]
```
which would yield

When I user top 100 percent, throwing different error like one of the coloumn used many times<issue_comment>username_1: What part of the error message do you not understand? The `ORDER BY` should only be in the outermost query.
SQL tables and results sets represent *unordered* sets. This is true of subqueries and CTEs as well. The one exception is that the `ORDER BY` is allowed in the outermost query to order the result set.
```
WITH ord_dupes AS (
SELECT ROW_NUMBER() OVER (PARTITION BY bas2."BudgetTask__c", bas2."BudgetResource__c"
ORDER BY bas2."LastModifiedDate" DESC
) as rk,
bas2.*, bas2dupes.* -- should list out the columns
FROM bas2 INNER JOIN
bas2dupes
ON bas2."BudgetTask__c" = bas2dupes."BudgetTask__c" AND
bas2."BudgetResource__c" = bas2dupes."BudgetResource__c"
)
SELECT od.*
FROM ord_dupes od
ORDER BY ? DESC ;
```
Your `ORDER BY` column is `"BudgetTask__r.BudgetHeader__r.Project__r.ProjectNumber__c"`. If that is the name of a column, then use it. But, if so, I strongly recommend that you fix your data model, so you are not using periods in column names.
Otherwise, just put the correct column for `?`.
Upvotes: 0 <issue_comment>username_2: Query is missing the selection of data from the CTE, so we can't see all of the query right now, the error is pretty clear though. It is invalid to order a CTE since the order it outputs in can be re-ordered by the select query which is using the CTE itself.
consider:
```
WITH foo as (
SELECT id,name FROM bar ORDER BY id ASC
)
SELECT * FROM foo ORDER BY name DESC
```
What is the meaning or purpose of the order within the CTE? if the query engine obeyed it, it would perform excess sort work for no purpose.
You perform ordering as your final step - ordering as an intermediate step *only* makes sense in the scenario of a TOP keyword where you want only a sub-set of data based on an order.

My goal is essentially manual stemming of a text string - amending several related terms into one term.
My code to do it individually works absolutely fine, but it would save me so much time if I could iterate it.
```
# dataframe of the collection of terms to be substituted into one term
Babanov_stem <- c("бабановдун", "бабановду", "бабановтун", "бабанову", "бабановту", "бабановго", "бабановко", "бабановым", "бабановдон", "бабановтон",
"бабанове", "бабановто", "babanova", "babanov", "babanovpresident",
"бабанова")
Babanov_seq <- seq(1:16)
Babanov <- data_frame(Babanov_seq, Babanov_stem)
# single code works fine
tidy_KG17pre$word2 <- str_replace_all(tidy_KG17pre$word2, Babanov$Babanov_stem[15], "бабанов")
```
The individual code works great, but I would really like to iterate - as I have to do this for approximately 25 terms but across 5 candidates (Babanov is candidate 1)
```
# My poor effort at a for loop

reduce(append)
```
I would be really grateful for any thoughts on how to get any of the above to work :)<issue_comment>username_1: I created a fake dataset to play with.
```
dtf <- data_frame(word = paste(Babanov_stem, "blabla"))
head(dtf)
# # A tibble: 6 x 1
# word
#
# 1 бабановдун blabla
# 2 бабановду blabla
# 3 бабановтун blabla
# 4 бабанову blabla
# 5 бабановту blabla
# 6 бабановго blabla
```
Replacing a single code as you suggested
```
dtf$word <- str_replace_all(dtf$word, Babanov$Babanov_stem[15], "бабанов")
```
Using a loop to replace any word in Babanov\_stem by the word "бабанов"
```
for (w in Babanov$Babanov_stem){
dtf$word <- str_replace_all(dtf$word, w, "бабанов")
}
head(dtf)
# # A tibble: 6 x 1
# word
#
# 1 бабанов blabla
# 2 бабанов blabla
# 3 бабанов blabla
# 4 бабанов blabla
# 5 бабанов blabla
# 6 бабанов blabla
```
Note: You don't need `seq()` in the `for` loop.
The loop above uses modification in place. It may be a case where functional programming is not recommended. See [Loops that should be left as is](http://adv-r.had.co.nz/Functionals.html#functionals-not) in Hadley wickham's book on Advanced R programming.

The best way to do it is to use 'stringr' to adapt the common function used to extract URL's in text mining. That command takes a string with 'www.' in it and extracts it replacing it with a 'space'
I did the same, but instead of the 'www.' I used the stem of the Candidates name. It was fine in latin alphabet or cyrillic
```
str_replace_all(KG17$message, "бабан[^[:blank:]]+", "babanov")
```

2018/03/20 | 1,146 | 3,452 | <issue_start>username_0: My directory contains the following files:
```
FILE1_h0_something_1950_other.gz
FILE2_h0_something_1950_other.gz
FILE3_h0_something_1950_other.gz
```
Here a portion of my bash script:
```
year=1950
for nc_gz in "$input_path/*h3*$year*.gz"; do
gunzip $nc_gz
done
```
I noted that SOMETIMES (strange behavior... I except always or never) a file named ***h3*1950**\* is created inside my dir.
The code fails when directory contains no gz files.
Where is the issue?<issue_comment>username_1: >

> ```
> for nc_gz in "$input_path/*h3*$year*.gz"; do

>

You're iterating over a list of one element. Since `"$input_path/*h3*$year*.gz"` is in double quotes, it's a single string. So if the value of `input_path` is `/some/where` and the value of `year` is `2017` then this runs the loop body once, with `nc_gz` set to `/some/where/*h3*2017*.gz`.
>
>
> ```
> gunzip $nc_gz
>
> ```
>
>
Here `$nc_gz` is unquoted, so this applies the [split+glob operator](https://unix.stackexchange.com/questions/171346/security-implications-of-forgetting-to-quote-a-variable-in-bash-posix-shells/171347#171347) to the result. In the example above, `/some/where/*h3*2017*.gz` is expanded to the list of matching files; except if there are no matching files, then this invokes `gunzip` with the argument `/some/where/*h3*2017*.gz`.
First, quote things properly:
* [Use double quotes around variable substitutions](https://unix.stackexchange.com/questions/131766/why-does-my-shell-script-choke-on-whitespace-or-other-special-characters).
* Don't use double quotes around wildcards.
```
for nc_gz in **"**$input_path/**"***h3***"**$year**"***.gz; do
gunzip **"**$nc_gz**"**
done
```
This still runs the loop once if the wildcard does not match any files, because of a shell misfeature that non-matching wildcard patterns are left unchanged instead of being expanded to an empty list. In bash (but not in plain sh), you can avoid this by setting the `nullglob` option.
```
#!/bin/bash
shopt -s nullglob
for nc_gz in "$input_path/"*h3*"$year"*.gz; do
gunzip "$nc_gz"
done
```
In plain sh, you can avoid this by skipping non-existent files.
```
for nc_gz in "$input_path/"*h3*"$year"*.gz; do
if [ ! -e "$nc_gz" ]; then continue; fi
gunzip "$nc_gz"
done
```
Note that I assumed that this was simplified code and you do need the loop to do other things beyond calling `gunzip`. If all you need to do is unzip the files, then you can call `gunzip` a single time, since it supports multiple file arguments.
```
gunzip "$input_path/"*h3*"$year"*.gz
```
This works in the sense of unzipping the files, and it does nothing if the wildcard pattern does not match any file, however gunzip will complain about the non-existent file. Here bash's `nullglob` option won't help you since calling `gunzip` with no file name also doesn't work (it expects to uncompress data from its standard input). You need to test for the number of matching files.
```
unzip_matching_files () {
if [ $# -eq 1 ] && [ ! -e "$1" ]; then return; fi
gunzip "$@"
}
unzip_matching_files "$input_path/"*h3*"$year"*.gz
```

2018/03/20 | 923 | 2,651 | <issue_start>username_0: I have three vectors in Matlab that are possibly of different sizes. I want to compare the values in each vector against all the other values in the other vectors and only keep values that are 'close' in 2 out of 3 of the vectors. And by 'keep', I mean take the average of the close values.
For example:
```
a = [10+8i, 20];
b = [10+9i, 30, 40+3i, 55];
c = [10, 60, 41+3i];
```
If I set a closeness tolerance such that only values that are within, say, a magnitude of 1.5 of each other are kept, then the following values should be marked as close:
* 10 + 8i and 10 + 9i
* 40 + 3i and 41 + 3i
Then the routine should return a vector of length that contains the average of each of these sets of numbers:
```
finalVec = [10+8.5i,40.5+3i];
```
What is the most efficient way to do this in Matlab? Is there a better way than just straightforward looping over all elements?<issue_comment>username_1: Building on [this solution](https://fr.mathworks.com/matlabcentral/answers/98191-how-can-i-obtain-all-possible-combinations-of-given-vectors-in-matlab):
```
a = [10+8i, 20];
b = [10+9i, 30, 40+3i, 55];
c = [10, 60, 41+3i];
M1 = compare_vectors(a , b);
M2 = compare_vectors(a , c);
M3 = compare_vectors(b , c);
finalVec = [M1, M2 , M3]
function M = compare_vectors(a , b)
% All combinations of vectors elements
[A,B] = meshgrid(a,b);
C = cat(2,A',B');
D = reshape(C,[],2);
% Find differences lower than tolerance
tolerance = 1.5
below_tolerance = abs(D(:,1) - D(:,2)) < tolerance ;
% If none, return empty
if all(below_tolerance== 0)
M = [];
return
end
% Calculate average of returned values
M = mean(D(below_tolerance,:));
end
```

% your data
a = [10+8i, 20];
b = [10+9i, 30, 40+3i, 55];
c = [10, 60, 41+3i];
tol = 1.5;
% call the function with each combination of vectors and concatenate the results
finalVec = cell2mat(cellfun(@closepoints, {a, a, b}, {b, c, c}, {tol, tol, tol}, 'Uni', 0))
function p = closepoints(a, b, tol)
% find the pairs of indexes of close points
% the bsxfun() part calculates the distance between all combinations of elements of the two vectors
[ii,jj] = find(abs(bsxfun(@minus, a, b.')) < tol);
% calculate the mean
p = (a(jj) + b(ii))/2;
end
```
Note that [cellfun()](https://de.mathworks.com/help/matlab/ref/cellfun.html) isn't really faster than calling the function multiple times in a row or using a for loop. But it would be easier to add more vectors than the former and is IMO nicer to look at than the latter.

How can i make block like image? And can we make this arrow height responsive?<issue_comment>username_1: I would consider a mix of skew transformation, inset box-shadow and some linear-gradient:

border-left: none;
box-shadow: -2px 2px 0px #fff inset;

transform-origin: top left;
z-index: -1;
}
.block-arr:after {

position: absolute;
top: 50%;
bottom: 0;

right: 0;
background: purple;
border: 5px solid purple;
border-top: none;
border-left: none;
box-shadow: -2px -2px 0px #fff inset;
transform: skew(-25deg);
transform-origin: bottom left;
z-index: -1;
}
```
```html
**Main Heading**
Sub Heading
**Main Heading**
Sub Heading
```
And here is a more compressed version with some CSS variable to easily handle color. You can also do the same to handle others variables:
```css
* {
box-sizing: border-box;
}
.block-arr {
--c1:purple;
--c2:#fff;
padding: 50px;
margin: 20px;
margin-right: 100px;
position: relative;
background: linear-gradient(var(--c2), var(--c2))2px 0/2px 100% no-repeat, var(--c1);
border-left: 2px solid var(--c1);
z-index: 0;
}
.block-arr:before,
.block-arr:after {
left: 0;
right: 0;
content: "";
position: absolute;
background: var(--c1);
border: 5px solid var(--c1);
border-left: none;
z-index: -1;
}
.block-arr:before {
top: 0;
bottom: 50%;
border-bottom: none;
box-shadow: -2px 2px 0px var(--c2) inset;
transform: skew(25deg);
transform-origin: top left;
}
.block-arr:after {
top: 50%;
bottom: 0;
border-top: none;
box-shadow: -2px -2px 0px var(--c2) inset;
transform: skew(-25deg);
transform-origin: bottom left;
}
```
```html
**Main Heading**
Sub Heading
And yes it is reponsive and grow when height grow
```
**BONUS**
Another fancy and more complex way with only linear-gradient:
```css
* {
box-sizing: border-box;

2018/03/20 | 372 | 1,204 | <issue_start>username_0: I have a dataframe (spark) which has 2 columns each with list values. I want to create a new column which concatenates the 2 columns (as well as the list values inside the column).
For e.g.
Column 1 has a row value - [A,B]
Column 2 has a row value - [C,D]
**"The output should be in a new column i.e. "**
Column 3(newly created column) with row value - [A,B,C,D]
**Note:-
Column values have values stored in LIST**
Please help me implement this with pyspark.
Thanks<issue_comment>username_1: we can use an UDF as,
```
>>> from pyspark.sql import functions as F
>>> from pyspark.sql.types import *
>>> udf1 = F.udf(lambda x,y : x+y,ArrayType(StringType()))
>>> df = df.withColumn('col3',udf1('col1','col2'))
```
Upvotes: 3 [selected_answer]<issue_comment>username_2: as general rule, if you want to join more list columns, I suggest to use `chain` from `itertools`
```
from itertools import chain
concat_list_columns = F.udf(lambda *list_: chain(*list_), ArrayType(StringType()))
```
Because udf are heavy on memory, a better solution would be to use pyspark function concat:
```
from pyspark.sql import functions as F
F.concat(col1, col2, col3)

I need it to be a form at certain resolution AND form itself must not flicker to a user, so somehow in background it need to make an screenshot at certain form dimension.
I tried various things but i cannot make form resized without actually resize a window and than take a screenshot. It's anoying since, to user a window will flicker in mean time -> go to resolution -> make screen shot -> go back to old resolution.
Making a deep-copy of form is a more or less no go since it would needed a lot of rewriting things.
I tried things like: [Attempt 1](https://www.developerfusion.com/code/4630/capture-a-screen-shot/) | [Attempt 2](http://www.xtremedotnettalk.com/graphics-and-multimedia/95011-capture-hidden-window-top-level.html) | [Attempt 3](https://www.daniweb.com/programming/software-development/threads/260393/get-bitmap-of-hidden-window)
But still problem with resizing window and flicker from one size to other.
I have dotnet 2.0 (don't ask why).<issue_comment>username_1: This is a very specific problem, and I'm sure there are no real code solutions for that. This is a design-technical issue, and some possible ways to avoid this are
1. You don't resize the form back,
2. You make screenshots only possible in your specific size,
3. You disable the resizing in general and set your size to the default size.

The errors I am seeing in Xcode are :
```
diff: /Podfile.lock: No such file or directory
diff: /Manifest.lock: No such file or directory
error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.
```
I have tried the following based on information that I have to seem on other Stackoverflow.
1: Close Xcode and run pod install
2: pod update
3: Remove and reinstall cocoa pods
4: create a new project
My project has the structure `/platform/ios` and I am trying to install Firebase. This what I have done to install the pods
1: In the folder above -- pod init
2: edit the podfile and add the firebase
the podfile content
```
# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'
target 'RandstadJobs' do
# Uncomment the next line if you're using Swift or would like to use dynamic frameworks
# use_frameworks!
# Pods for RandstadJobs
pod 'Firebase/Core'
end
```
3: run pod install
4: open Xcode clean and build
I see the Podfile.lock and the Manifest.lock file. They are in the folder,,
```
/platform/ios/Podfile.lock and /platform/ios/pods/manifest.lock
```
Here is the build phase setting in Xcode
```
diff "${PODS_PODFILE_DIR_PATH}/Podfile.lock" "${PODS_ROOT}/Manifest.lock" > /dev/null
if [ $? != 0 ] ; then
# print error to STDERR
echo "error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation." >&2
exit 1
fi
# This output is used by Xcode 'outputs' to avoid re-running this script phase.
echo "SUCCESS" > "${SCRIPT_OUTPUT_FILE_0}"
```
It seems like the path is not getting set.
Can you please give some hints and how to resolve this issue

so, it's 1+1+n+n-1+1+1 = 2n+3, is it correct?

Please follow below mention step to enable mod\_rewrite module:
1) Find the “httpd.conf” file under the “conf” folder inside the Apache’s installation folder.
2) Find the following line “#LoadModule rewrite\_module modules/mod\_rewrite.so” in the “httpd.conf” file.You can do this easily by searching the keyword “mod\_rewrite” from find menu.
3) Remove the “#” at the starting of the line, “#” represents that line is commented.
4) Now restart the apache server.
5) You can see now “mod\_rewrite” in the Loaded Module section while doing “phpinfo()”.

2018/03/20 | 854 | 2,974 | <issue_start>username_0: I am trying to pass an array of floats (in my case an audio wave) to a fragment shader via texture. It works but I get some imperfections as if the value read from the 1px height texture wasn't reliable.
[](https://i.stack.imgur.com/CCU1U.png)
This happens with many combinations of bar widths and amounts.
I get the value from the texture with:
```
precision mediump float;
...
uniform sampler2D uDisp;
...
void main(){
...
float columnWidth = availableWidth / barsCount;
float barIndex = floor((coord.x-paddingH)/columnWidth);
float textureX = min( 1.0, (barIndex+1.0)/barsCount );
float barValue = texture2D(uDisp, vec2(textureX, 0.0)).r;
...
```
If instead of the value from the texture I use something else the issue doesn't seem to be there.
```
barValue = barIndex*0.1;
```
[](https://i.stack.imgur.com/mzyBe.png)
Any idea what could be the issue? Is using a texture for this purpose a bad idea?
I am using [Pixi.JS](http://www.pixijs.com/) as WebGL framework, so I don't have access to low level APIs.
With a gradient texture for the data and many bars the problems becomes pretty evident.
[](https://i.stack.imgur.com/3b8os.png)
**Update:** Looks like the issue relates to the consistency of the value of textureX.
Trying different formulas like `barIndex/(barsCount-1.0)` results in less noise. Wrapping it on a `min` definitely adds more noise.<issue_comment>username_1: Generally `mediump` is insufficient for texture coordinates for any non-trivial texture, so where possible use `highp`. This isn't always available on some older GPUs, so depending on the platform this may not solve your problem.
If you know you are doing 1:1 mapping then also use GL\_NEAREST rather than GL\_LINEAR, as the quantization effect will more likely hide some of the precision side-effects.
Given you probably know the number of columns and bars you can probably pre-compute some of the values on the CPU (e.g. precompute `1/columns` and pass that as a uniform) at fp32 precision. Passing in small values between 0 and 1 is always much better at preserving floating point accuracy, rather than passing in big values and then dividing out.
Upvotes: 0 <issue_comment>username_2: Turned out the issue wasn't in reading the values from the texture, but was in the drawing. Instead of using IFs I switched to step and the problem went away.
```
vec2 topLeft = vec2(
paddingH + (barIndex*columnWidth) + ((columnWidth-barWidthInPixels)*0.5),
top
);
vec2 bottomRight = vec2(
topLeft.x + barWidthInPixels,
bottom
);
vec2 tl = step(topLeft, coord);
vec2 br = 1.0-step(bottomRight, coord);
float blend = tl.x * tl.y * br.x * br.y;
```
I guess comparisons of floats through IFs are not very reliable in shaders.

I've tried a couple of things but nothing seems to work, the original colour is black and i can change it if i open the svg image in my IDE and add/change the fill attribute. But not with JS. What am I doing wrong? Other lines of code work fine so it is not a problem with the files or so.
So far i've tried these lines of codes and put id on the img tag aswell as the svg element it self
html:
```
```
JS:
```
$('#myId').css({fill:"#f8b9d4"});
$("myId").attr("fill", "yellow");
document.getElementById("myId").setAttribute("fill", "#f8b9d4");
xml version="1.0" encoding="UTF-8" standalone="no"?
random title
```
UPDATE - created a completley new project but the problem is the same. (The div is for testing and working fine)
HTML:
```
Title
```
jquery:
```
$(document).ready(function () {
$('#myId').css({fill:"blue"});
$("#h").text("heasdadasdsadasdsad");
});
```
SVG file:
```
random title
```<issue_comment>username_1: Your Jquery css works fine. You don't need to have an empty `fill=""` attribute on the `path`.

If you cannot put the directly in your HTML, embed it using the tag, e.g. like this:

Your browsser doesn't support SVG
```
Then, you can access elements inside the like this:
```
document.getElementById("img").contentDocument.getElementById("myId").setAttribute("fill", "#f8b9d4");

I am using `BluetoothSocket` class, I am sending and receiving data with the help of input and output streams.
when App receives large amount of data from input stream, I am killing my app forcefully and after it I am again restarting my app, but `InputStream` returns me previous data, which is not needed anymore.how to discard that old data?
has Anyone Some Solution for this Issue?
**Following is my source code:**
```
public class MyBluetoothService {

}
mmInStream = tmpIn;
mmOutStream = tmpOut;
}
public void run() {
mmBuffer = new byte[1024];
int numBytes; // bytes returned from read()
// Keep listening to the InputStream until an exception occurs.
while (true) {
try {
// Read from the InputStream.

// Send the obtained bytes to the UI activity.

} catch (IOException e) {

break;
}
}
}
// Call this from the main activity to send data to the remote device.

// Share the sent message with the UI activity.
Message writtenMsg = mHandler.obtainMessage(
MessageConstants.MESSAGE_WRITE, -1, -1, mmBuffer);
writtenMsg.sendToTarget();
} catch (IOException e) {
Log.e(TAG, "Error occurred when sending data", e);
// Send a failure message back to the activity.

public void cancel() {
try {
mmSocket.close();
} catch (IOException e) {
Log.e(TAG, "Could not close the connect socket", e);
}
}
}
}
```<issue_comment>username_1: I think you should close the socket to manage the bug.
I recommend you to do this in finalizer like the code below.
```
private class ConnectedThread extends Thread
{
private final BluetoothSocket mmSocket;
private final InputStream mmInStream;
private final OutputStream mmOutStream;
private byte[] mmBuffer; // mmBuffer store for the stream
@override
protected void finalize() throws Throwable
{
try
{
cancel();
}
finally
{
super.finalize();
}
}
...
```
Also as I mentioned in comment, it is safer to close every `stream`s before closing the socket.
So, try this `cancel()` method.
```
// Call this method from the main activity to shut down the connection.
public void cancel()

And [more information](https://dzone.com/articles/java-what-does-finalize-do-and) about `finalize` method.
**EDIT: bold ones are important than other suggestions.**
Reading comments of EJP I understood why your app stops when you get large data : you maybe have to clear buffers before calling `read()`. And he says that finalizer can happen not to be called by system (I don't know why).
**How about** `break`**ing the loop when the** `read()` **returned** `-1`?
And just now I found a helpful [link](http://www.gregbugaj.com/?p=283) about proper method to read a stream. I hope it helped.
Code cited from the link

*Also*
Though the `finalizer` may be able not to be called by system closing `streams` before closing `sockets` is safer (I read some SO threads before).

// Keep listening to the InputStream until an exception occurs
```
The problem is here. You should keep reading from the stream until *end of stream or* an exception occurs. You need to break out of the read loop if `read()` returns -1.
At present you are reading beyond end of stream, and ignoring the condition altogether, so of course the data that was in the buffer on the last successful read is still there.
For your application to keep *seeing* that data, you must also be ignoring the read count and assuming the buffer was filled, which also is invalid.

2018/03/20 | 691 | 2,735 | <issue_start>username_0: Hello I am attepting to make a webpage to dowload reports from amazon seller central using the MWS API. The issue im running into is that 3 different calls are needed to download one report!
Request report and get its ID-> check status/get report ID -> download report.
Currently I have this running of 3 separate buttons which need to be clicked in order, how would I go about making the second api call wait for the frist one to return a specific value and so on.
<http://docs.developer.amazonservices.com/en_UK/reports/index.html><issue_comment>username_1: You basically have two options:
1. Have a long running PHP process which does it all in one go. You might have to flush() data to the client so that it doesn't appear to hang.
2. Have different PHP scripts doing the three parts (you might want to combine step 2 and 3) and call them through JavaScript in a "polling loop".
Since MWS reports can sometimes take very long (on occasion >1 hr), you'll probably have to change PHP settings to allow such a long running script. I'd personally go with method 2.
Upvotes: 1 [selected_answer]<issue_comment>username_2: Since you say you are doing this from a webpage, I assume your language of choice is JavaScript. Here are JavaScript examples of making a call, and chaining other calls to it. Depending on the library/framework you are using, you can leverage promises, observables or callbacks.
**Promises** (don't forget to check for errors, I don't check in my example):
```
http.get(reportUrl).then(reportResponse => {
http.get(checkStatusUrl + reportResponse.id).then(statusResponse => {
http.get(finalUrl + statusResponse.id).then(finalResponse => {
console.log(finalResponse);
})
})
})
```
**Observables**:
```
http.get(reportUrl).subscribe(reportResponse => {
http.get(checkStatusUrl + reportResponse.id).subscribe(statusResponse => {
http.get(finalUrl + statusResponse.id).subscribe(finalResponse => {
console.log(finalResponse);
})
})
})
```
**Callbacks**:
```
http.get(reportUrl, reportResponse => {
http.get(checkStatusUrl + reportResponse.id, statusResponse => {
http.get(finalUrl + statusResponse.id, finalResponse => {
console.log(finalResponse);
})
})
})
```
---
If you're using a server-side language, your API should look more or less the same. Make the first request, wait for its response. Use the response to make the second request, and so on.

2018/03/20 | 898 | 3,076 | <issue_start>username_0: I have two tables permissions and groups of many to many relationship
```
CREATE TABLE `permissions` (
`Permission_Id` int(11) NOT NULL AUTO_INCREMENT,
`Permission_Name` varchar(50) DEFAULT NULL,
PRIMARY KEY (`Permission_Id`)
)
```
Groups table
```
CREATE TABLE `groups` (
`Group_Id` int(11) NOT NULL AUTO_INCREMENT,
`Group_Desc` varchar(100) DEFAULT NULL,
PRIMARY KEY (`Group_Id`)
)
```
I am confuse how to implement the many to many relationship
which is better to create a composite primary key of Group\_id and Permission\_id in a new table
Or to create a new table & select the columns from the two table using join keyword .<issue_comment>username_1: I know the solution.
I need a to create "junction" table to hold many-to-many relationship in this case.
```
CREATE TABLE Groups_Permissions
(
Group_Id INT,
Permission_Id INT,
)
```
The combination of Group\_Id and Permmission\_Id should be UNIQUE and have FK to groups and permission tables.
Upvotes: 1 [selected_answer]<issue_comment>username_2: From [*my blog*](http://mysql.rjweb.org/doc.php/index_cookbook_mysql#many_to_many_mapping_table):
Do it this way.
```
CREATE TABLE XtoY (
# No surrogate id for this table
x_id MEDIUMINT UNSIGNED NOT NULL, -- For JOINing to one table
y_id MEDIUMINT UNSIGNED NOT NULL, -- For JOINing to the other table
# Include other fields specific to the 'relation'
PRIMARY KEY(x_id, y_id), -- When starting with X
INDEX (y_id, x_id) -- When starting with Y
) ENGINE=InnoDB;
```
Notes:
```
⚈ Lack of an AUTO_INCREMENT id for this table -- The PK given is the 'natural' PK; there is no good reason for a surrogate.
⚈ "MEDIUMINT" -- This is a reminder that all INTs should be made as small as is safe (smaller ⇒ faster). Of course the declaration here must match the definition in the table being linked to.
⚈ "UNSIGNED" -- Nearly all INTs may as well be declared non-negative
⚈ "NOT NULL" -- Well, that's true, isn't it?
⚈ "InnoDB" -- More effecient than MyISAM because of the way the PRIMARY KEY is clustered with the data in InnoDB.
⚈ "INDEX(y_id, x_id)" -- The PRIMARY KEY makes it efficient to go one direction; this index makes the other direction efficient. No need to say UNIQUE; that would be extra effort on INSERTs.
⚈ In the secondary index, saying just INDEX(y_id) would work because it would implicit include x_id. But I would rather make it more obvious that I am hoping for a 'covering' index.
```
To conditionally INSERT new links, use IODKU
Note that if you had an AUTO\_INCREMENT in this table, IODKU would "burn" ids quite rapidly.
**More**
A `FOREIGN KEY` implicitly creates an index on the column(s) involved.
`PRIMARY KEY(a,b)` (1) says that the combo `(a,b)` is `UNIQUE`, and (2) orders the data by `(a,b)`.
`INDEX(a), INDEX(b)` (whether generated by `FOREIGN KEY` or generated manually) is *not* the same as `INDEX(a,b)`.
InnoDB really needs a `PRIMARY KEY`, so you may as well say `PRIMARY KEY (a,b)` *instead of* `UNIQUE(a,b)`.

2018/03/20 | 498 | 1,835 | <issue_start>username_0: I have a very large dataset in NetCDF4 format. Normally I would just read the variables I need and pass them as attributes to my custom class so I can create new methods for post processing. Since this dataset is so large, this is not an option as it throws a memory error. So I want to extend the attributes of the NetCDF4 Dataset instead. The following code illustrates what I'm trying to do:
```
import netCDF4
class output(NetCDF4.Dataset):
def __init__(self, path):
super(NetCDF4.Dataset, self).__init__(path)
print(self.variables) # Prints successfully
def my_new_method(self):
print(self.variables) # AttributeError: 'output' object has no attribute 'variables'
```<issue_comment>username_1: Your `super()` syntax is incorrect. Consider
```
class output(netCDF4.Dataset):
def __init__(self, path):
super(output, self).__init__(path)
print(self.variables)
def my_new_method(self):
print(self.variables)
```
The basic syntax of `super()` in Python has been discussed here before (see the linked [post](https://stackoverflow.com/q/222877/1328439))
With this definition I could type
```
my_output=output("myhdf.hdf")
my_output.my_new_method()
```
Both commands output the list of variables.
Upvotes: 2 [selected_answer]<issue_comment>username_2: The NetCDF4 developers helped me further, and this is the actual way of doing it:
```
import netCDF4
class output(netCDF4.Dataset):
def __init__(self, *args, **kwargs):
super(output, self).__init__(*args, **kwargs)
def my_new_method(self):
print(self.variables)
```
As pointed out by <NAME> (see accepted answer) the super syntax was incorrect, but also one needs to pass \*args and \*\*kwargs or else you you will get additional errors.

2018/03/20 | 887 | 2,725 | <issue_start>username_0: I am trying to incorporate css styles associated with particular div class names using node.style. I can get the styles to work individually but I am trying to implement multiple styles that span within one another using the div classes mentioned. I am wondering if there is a way of doing this using an easier method or can it be done at all?
```
var node = document.createElement("wall-post");
var image = new Image();
image.src = obj.picture;
node.appendChild(image);
node.style=' display: inline-block;margin: 15px;margin-top: 30px; border-radius: px;overflow-y: hidden;box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);float:left;';
document.body.appendChild(node);
```<issue_comment>username_1: You can also use `node.className = "yourclass"` and use css to define the styling of that class
```
.yourclass {
display: inline-block;
margin: 15px;
margin-top: 30px;
border-radius: px;
overflow-y: hidden;
box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
float:left;
}
```
Upvotes: 2 [selected_answer]<issue_comment>username_2: The `style` **property** on an element isn't a string, it's an *object* with properties for the styles. You set them individually.
```
node.style.display = 'inline-block';
node.style.margin = '15px';
node.style.marginTop = '30px';
node.style.borderRadius = /*?? Your question just has 'px' */;
node.style.overflowY = 'hidden';
node.style.boxShadow = '0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19)';
node.style.float = 'left';
```
Note that you use the `camelCase` version (well, or `node.style["margin-top"] = "..."`).
Alternately, if you want to completely replace the style, you can do that by using `setAttribute` to replace the `style` entirely:
```
node.setAttribute('style', ' display: inline-block;margin: 15px;margin-top: 30px; border-radius: px;overflow-y: hidden;box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);float:left;');
```
---
All of that aside: In general, supplying style information in JavaScript code isn't a great pattern to follow. Create a descriptive class, then use that class on the element.
Upvotes: 2 <issue_comment>username_3: The `style` property is related to the `style` attribute which accepts, as its value, the **body** of a CSS rule-set. It associates those rules with the particular element.
Selectors, including class selectors, appear outside the rule-set's body and cannot be included in a style attribute. (It doesn't make sense to do so anyway, the style attribute is associated with a specific element, so there is no point is selecting a different one from that context).

Now I want to find out the index of "BIB1". I already tried the IndexOf()-Method which should create the output "0" but it gives me "-1" instead, because it can't find the value. How can I get the index of "BIB1"?<issue_comment>username_1: Check first in info.plist that your app is authorized to access photos from library. than Use the below code to access all photos:
```
PHPhotoLibrary.requestAuthorization { (status) in
switch status {
case .authorized:
print("You Are Authrized To Access")
let fetchOptions = PHFetchOptions()
let allPhotos = PHAsset.fetchAssets(with: .image, options: fetchOptions)
print("Found number of: \(allPhotos.count) images")
case .denied, .restricted:
print("Not allowed")
case .notDetermined:
print("Not determined yet")
}
}

first import photos
```
import Photos
```
then declare Array for store photo before viewDidLoad()
```
var allPhotos : PHFetchResult? = nil
```
Now write code for fetch photo in viewDidLoad()
```
/// Load Photos
PHPhotoLibrary.requestAuthorization { (status) in
switch status {
case .authorized:
print("Good to proceed")
let fetchOptions = PHFetchOptions()
self.allPhotos = PHAsset.fetchAssets(with: .image, options: fetchOptions)
case .denied, .restricted:
print("Not allowed")
case .notDetermined:
print("Not determined yet")
}
}
```
Now write this code for display image from Array
```
/// Display Photo
let asset = allPhotos?.object(at: indexPath.row)
self.imageview.fetchImage(asset: asset!, contentMode: .aspectFit, targetSize: self.imageview.frame.size)
// Or Display image in Collection View cell
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = self.collectionView.dequeueReusableCell(withReuseIdentifier: "photoCell", for: indexPath) as! SelectPhotoCell
let asset = allPhotos?.object(at: indexPath.row)
cell.imgPicture.fetchImage(asset: asset!, contentMode: .aspectFit, targetSize: cell.imgPicture.frame.size)
return cell
}
extension UIImageView{
func fetchImage(asset: PHAsset, contentMode: PHImageContentMode, targetSize: CGSize) {
let options = PHImageRequestOptions()
options.version = .original
PHImageManager.default().requestImage(for: asset, targetSize: targetSize, contentMode: contentMode, options: options) { image, _ in
guard let image = image else { return }
switch contentMode {
case .aspectFill:
self.contentMode = .scaleAspectFill

2018/03/20 | 1,117 | 4,526 | <issue_start>username_0: I have a project with multiple framework targets, that also have pods dependencies.
I have:
* No circular dependencies between targets
* Everything, including pods, is in Objective-C, no Swift at all.
* `use_frameworks!` in Podfile, so all pods are frameworks, not libraries.
Here is my structure:
* `TUSystemKit` depends on `TUModels` (which is a framework).
* `TUModels` depends on `Pods_TUModels` (generated by pods).
* `Pods_TUModels` depends on `JSONModel`
* `TUModels` is automatically linked with its own pod framework (which contains `JSONModel`).
* `TUSystemKit` has `TUModels` as target dependency.
* `TUSystemKit` is linked with `TUModels`.
Visually, the dependencies are like this:
`TUSystemKit` ➔ `TUModels` ➔ `Pods_TUModels` ➔ `JSONModel`
When I select `MyModels` as the build target in Xcode, build succeeds. However, when I select `TUSystemKit`, the build fails, saying that module `JSONModel` is not found *while building module* `TUSystemKit` (`TUUser` in screenshot belongs to `TUModels`):
[](https://i.stack.imgur.com/z3gIk.jpg)
What am I doing wrong? Obviously I shouldn't be explicitly linking against all the frameworks in the dependency tree. Why does `TUModels` build perfectly but `TUSystemKit` errs on *a module import inside a linked framework's code*? Do I need to change something with pods?<issue_comment>username_1: After hours of refactoring, I've managed to build my project. I can't tell what exactly was wrong as it took me literally a day to organize all the dependencies and frameworks and it kept failing at a different point, more than a 100 times, but here are some observations to lead to a successful build:
* All the public-facing classes are added as public headers to the target, and not to any other target.
* All the code (.m files) are in Compile Sources section of the target, and not in any other target.
* All the public facing classes' headers are included at umbrella header (a header with the exact same name with the framework)
* The application embeds all the custom frameworks (not the pods).
* All the files inside a framework target only `#import` required files within the same target or a file listed on any targets umbrella header that the framework has a dependency on.
* Obvious, redundant, but worth noting again: **no classes between frameworks should have circular dependencies** (e.g. ClassA in FrameworkA depends on ClassB in FrameworkB, while some class in FrameworkB depends on some class on FrameworkA). I had some, and created delegates. Do whatever pattern fits your design: IoT/dependency injection, notifications/publisher-subscriber etc. But do it: separate the concerns clearly.
* Try to avoid using same classes in multiple targets. Instead, have it in one target, and make the other target depend on the containing target, creating a dependency chain.
After refactoring many files and playing with project settings, I managed to build and run everything again. My previous setup had various number of combinations of the issues that I mentioned above, messing everything up. After cleaning all the bits and grouping code into functional, modular frameworks, I could build it.
Upvotes: 2 [selected_answer]<issue_comment>username_2: If you came here due to the **parse error -> module not found**,
in certain occasions you may be forced to add the path manually.
This is...
* go to **your project** at the top
* select your project **target**
* select **build settings**
* search the parameter **Framework Search Paths** under the title **Search Paths**
* add the one where yours is located. Example: (using cocoa pods) **$(SRCROOT)/Pods**
* indicate/set it to be **recursive** (access to the option by double-clicking your previously added path)
The problem should have been resolved by the 3erd party lib with commands like **install / update / build** or similar but if it fails and you are stuck, this is an option in order to continue.
In the same tone, if you get an error from pods indicating that
**The sandbox is not in sync with the Podfile** because the builder is unable to find files like **Podfile.lock**, then you may consider to go in the same direction adding some user-defined settings:
* select **build settings**
* press the '+' symbol, "Add User-Defined Setting".
* add this pair:
+ param= **PODS\_PODFILE\_DIR\_PATH** value = **${SRCROOT}/.**
+ param = **PODS\_ROOT** value = **${SRCROOT}/Pods**

```

6 +/+ +/+ +/-
16 -/- +/+ +/+
20 +/- +/+ +/+
21 +/- +/+ +/+
22 +/+ +/+ -/-
25 +/+ +/+ +/+
```
For each column, I need to compare the string of one row with the string in the next one, and based on the values, report a number with AWK, based on the following comparison table (no matter the order of field1 and field2):
```
field1 field2 value
+/+ +/+ 0
+/+ +/- 0.5
+/- +/- 1
+/+ -/- 2
+/- -/- 2.5
-/- -/- 4

16 -/- +/+ +/+ 2.5 0 0
20 +/- +/+ +/+ 1 0 0

2018/03/20 | 657 | 2,293 | <issue_start>username_0: I use InnovaEditor to create edit block.
I try to find way in order to set dynamic height of edit block.
Ie block height should correspond block content.
**HTML:**
```
12345
```
What I did:
1) set keyup event in iframe body
2) wrap to content to get real height
3) set calculated height to the iframe
**Javascript:**
```
var $iframe = $("iframe#idContenteditor_field_1");
var $iframeBody = $iframe.contents().find("body");
$iframeBody.keyup(function(e) {
if ($(this).find('.content').length === 0) {
// add wrap
var bodyContent = $(this).html();
$(this).html('' + bodyContent + '');
}
var $contentBlock = $(this).find('.content');
var bodyHeight = $contentBlock.outerHeight();
$('#idContenteditor_field_1').height(bodyHeight); // set real height
});
```
It works fine.
The issue:
I have 10 edit blocks on the page and they are same except id.
But I have problems when I try to apply this code to all iframes.
```
// return all iframes
var $iframes = $('iframe[id^="idContenteditor_field_"]');
// return only single body of first iframe.
var $iframesBody = $iframes .contents().find("body");
```
So I can't set keyup event for all iframes.
Could you help me?
Maybe there is easier way to set dynamic height?<issue_comment>username_1: I haven't tested this code, but something like below should work.
You just need to iterate through your objects and set the event listener for each one in turn.
```
var $iframes = $('iframe[id^="idContenteditor_field_"]');
$iframes.each(function(index, item) {
var $iframeBody = $(item).contents().find("body");
$iframeBody.keyup(function(e) {
if ($(this).find('.content').length === 0) {
// add wrap
var bodyContent = $(this).html();
$(this).html('' + bodyContent + '');
}
var $contentBlock = $(this).find('.content');
var bodyHeight = $contentBlock.outerHeight();
$(item).height(bodyHeight); // set real height
});
});
```

I have installed Anaconda and I plan to use Spyder for python development. I also have a older version of Python installed on the same machine elsewhere.
I needed to get my hands on a package to use in Spyder which I needed to download and install.
I downloaded and installed pip directly from the website and then I used this in the command line of the older python install to obtain the package I required.
However I don't understand how I go about making this available to Spyder. I believe it works on a folder structure within it's own directory and I am unsure how to change this to get the package I have already downloaded.
I thought I might be able to copy it across, or point it at the directory where the package was downloaded to but I cannot work out how to do this.
I also tried using pip from within Spyder to work but it cannot find it.

Is there a way I can change the error color here? I know I can disable it completely with `problems.decorations.enabled`, but I would prefer to have them enabled, but just not be so hard on the eyes. I've gone through the theme customizations available [here](https://code.visualstudio.com/docs/getstarted/theme-color-reference), but I haven't found anything related the the `problems.decorations`.<issue_comment>username_1: There are two other settings you can look at:
```
"explorer.decorations.colors": false,
"explorer.decorations.badges": false
```
and some colorCustomizations (see [git decorator colors](https://code.visualstudio.com/docs/getstarted/theme-color-reference#_git-colors))

However, there doesn't seem to be a way to change the color of the problem colors. Modified, untracked and ignored all work fine though. You can change the file name color back to uncolored with the
```
"explorer.decorations.colors": false,
```
setting.

```
"list.errorForeground": "#00AA00"
```
This will change the color to green ("#00AA00").
In my case, I used it to add color to the High Contrast Theme because, for some reason, it was missing the error color in the file explorer.
Here's what I changed for that specific theme:
```
"workbench.colorCustomizations": {
"[Default High Contrast]": {
"list.errorForeground": "#00AA00"
}
}

to create a giant string and search by all fields using `like '%value%'` . It works fine, but for some records some fields are null. e.g if `actId` is null, my whole concat\_ws returns null. I don't know why, concat\_ws must ignore null values. May be it's because hibernate trying to call getActNumber from null? anyway I'm trying hard to resolve this problem.
```
where CONCAT_WS("_", actItemId.actId.actNumber, DATE_FORMAT(recordDate, '%d.%m.%Y'), actItemId.techniqueId.name, fzkActNumber, ....etc) like '%value%'

Basically sReplace = Replace(sReplace, Range"A1", "Range"B1:B10")
```
Private Sub CommandButton1_Click()

```
With Worksheets("NameOfTheWorksheet")
sReplace = Replace(sReplace, .Range("A1"), .Range("A2"))
End With
```

Replaces the values in Range `B1:B10` where it matches `sReplace`, with the value from Range `A1`
```
Range("B1:B10").Replace What:=sReplace, Replacement:=Range("A1"), LookAt:=xlPart, _
SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
ReplaceFormat:=False

2018/03/20 | 1,912 | 7,353 | <issue_start>username_0: I have recently upgraded my Visual Studio environment, and now I seem to have a problem with my .Net framework, as you can see in following error message:
>
> 9> C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets(1126,5): error MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.5" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.
>
>
>
(the number "9" is just a counter of the nineth project within my Visual Studio solution)
Let me explain you what's so confusing about this situation:
When I load my solution, I get following error message:
>
> The C# project ... is targeting ".NETFramework,Version=4.5", which is not installed on this machine. To proceed, select an option below:
>
>
>
* Change the target to .NET Framework 4.6.1. You can change back to ".NETFramework,Version=4.5" at a later time.
* Download the targeting pack for ".NETFramework,Version=4.5". The project will not change.
* Do not load the project.
I choose for the second option, and I get following website: [.NET SDKs for Visual Studio](https://www.microsoft.com/net/download/visual-studio-sdks)
This gives the following: list of .NET Frameworks:
```
4.7.1 Developer Pack, included in Visual Studio 2017 Runtime Release Details
4.7 Developer Pack, included in Visual Studio 2017 Runtime Release Details
4.6.2 Developer Pack, included in Visual Studio 2017 Runtime Release Details
4.6.1 Developer Pack, included in Visual Studio 2017 Runtime Release Details
4.6 Developer Pack, included in Visual Studio 2017 Runtime Release Details
4.5.2 Developer Pack, included in Visual Studio 2017 Runtime Release Details
3.5 SP1 Developer Pack, included in Visual Studio 2017 Runtime Release Details
```
=> Where is 4.5?
I have already different times downloaded 4.5.2 version, Developer Pack as well as Runtime, but nothing changes.
So, after a while, I just close the dialog box about the missing target. I'm expecting to get a more readable error message, once I get to the compilation of the project.
Next to that, I've also investigated the installation of my PC (PC settings, Add and Remove Programs), this gives following list:
```
Microsoft .NET Core SDK - 2.1.4 (x64)
Microsoft .NET Framework 4.5 SDK
Microsoft .NET Framework 4.5.1 Multi-Targeting Pack (ENU)
Microsoft .NET Framework 4.5.1 SDK
Microsoft .NET Framework 4.5.2 Multi-Targeting Pack (ENU)
Microsoft .NET Framework 4.6 Targeting Pack
Microsoft .NET Framework 4.6.2 SDK
Microsoft .NET Framework 4.6.2 Targeting Pack
Microsoft .NET Framework 4.7 SDK
Microsoft .NET Framework 4.7 Targeting Pack
```
=> Ok, there seems not to be a targeting pack for 4.5 (only the SDK seems to be present), but what to do about it?
The error message speaks about retargeting my application, but that's out of the question: I'm the only person, having this problem, and modifying the configuration of a central application is not a solution.
The error message also speaks about the so-called "Global Assembly Cache" which will be used in place of reference assemblies. So, let's have a look at those things:
I seem to have two reference assemblies on my PC:
>
> C:\Program Files\Reference Assemblies\Microsoft\Framework (seems only to contain "v3.0" and "v3.5" directories)
>
> C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.
>
>
>
The latter seems to contain a ".NETFramework" directory, which, at his turn, contains a "v4.5" subdirectory, containing quite some XML files.
The error message however states that those are not used, the "Global Assembly Cache (GAC)" is used instead. If I try finding this, I find references to `gacutil`, `sn -k ...` and other programs which are not found on my PC for the specied .Net framework.
If I look, using Google, for "Microsoft .Net Framework 4.5 Targeting Pack" (exact phrase), I get zero results.
So, in other words, I get a message about a missing piece of software on my PC. I get the opportunity to install it but the installation does nothing. Then I get a compilation error about this, which talks about a very general technology which seems not to exist following Google, the mostly used search engine on the internet. It mentions a technology (GAC) which might be used or not and who is found, either on `C:\Program Files` or `C:\Program Files (x86)`, and its corresponding tool (`gacutil`) seems only to exist on my PC for other versions.
Can anybody give me a push in the right direction here?
Thanks in advance<issue_comment>username_1: Meanwhile I've solved the issue, and it comes down to a general truth in working with computers:

In my case, it means the following:
The problem popped up when I had upgraded my Visual Studio version (using the Visual Studio Installer), so the solution consisted of starting that Visual Studio Installer again, and check some more features to be installed (I've now checked so many of them that I can't figure out which one exactly solved my problem).
The error message, preceeded by the dialog box, were just information about the PC internals which only led to ununderstandable sidetracks.

I removed any Build & Deploy on that by:

* set Configuration to All Configurations

then uncheck reactApp for Build and Deploy.

```
\Route::group(['middleware' => 'web'], function ()
flash('Error message');
return Redirect::back();

And tried showing it my view with:
```
@include('flash::message')

However this just seems not to show the message.
I've been looking over the web for some good 2 to 3 hours now and I am at a loss right now.
If this is a duplication of another question somewhere on stackoverflow, then sorry!<issue_comment>username_1: In controller

web.php
```
Route::get('/',
function () {
Session::flash('error', 'test');
return view('welcome');
});
```
In your `.blade` view file you can access the message using
```
@if (session('error'))
{{ session('error') }}
@endif
```
You could replace `'error'` with any type of message ('success', 'warning', 'yourOwnMessageIdentifier etc) you'd want to flash.

2018/03/20 | 875 | 3,429 | <issue_start>username_0: What I would like to be able to do is for user to click button on my website (actually a webapp that runs locally on user machine so each instance is single user) which initiates a Google image search with various params set and display the results in a section of my html page.
This is because the idea is they can then select an image and drag and drop it onto a dropzone on my webpage. This parts works but currently the search is opening in a new tab so its a bit of a pain dragging from that tab to my tab.
Embedding as an iframe does not work, Google does not allow that.
So
a> is there a Google sanctioned API I can use to perform a Google search for images and display within my page.
b> Could I send send a url request from my server (i,e like curl/wget and then screenscrape the results and present on webpage<issue_comment>username_1: Google has retired the image search API, it is no longer available (see this SO thread with alternatives).
If you open up the URL you provided it will say this:
```

Creating `cx` and modifying it to search for images
===================================================
1. Create custom search engine at <https://cse.google.com/cse/create/new> based on your search criteria.
2. Choose sites to search (leave this blank if you want to search the entire web, otherwise you can enter a site to search in one particular site)
3. Enter a name and a language for your search engine.
4. Click "create." You can now find `cx` in your browser URL.
5. Under "Modify your search engine," click the "Control Panel" button. In the "edit" section you will find an "Image Search" label with an ON/OFF button, change it to **ON**. Click "update" to save your changes.
Conducting a search with the API
================================
The API endpoint url is [`https://www.googleapis.com/customsearch/v1`](https://www.googleapis.com/customsearch/v1)
The following JSON parameters are used for this API:
* `q`: specifies search text
* `num`: specifies number of results. Requires an integer value between 1 and 10 (inclusive)
* `start`: the "offset" for the results, which result the search should start at. Requires an integer value between 1 and 101.
* `imgSize`: the size of the image. I used `"medium"`
* `searchType`: must be set to `"image"`
* `filetype`: specifies the file type for the image. I used `"jpg", but you can leave this out if file extension doesn't matter to you.
* `key`: an API key, obtained from <https://console.developers.google.com/>
* `cx`: the custom search engine ID from the previous section
Simply make a `GET` request by passing above parameters as JSON to the API endpoint (also listed above).
**Note:** If you set a list of referrers in the search engine settings, visiting the URL via your browser will likely not work. You will need to make an AJAX call (or the equivalent from another language) from a server specified in this list. It will work for only the referrers which were specified in the configuration settings.

2018/03/20 | 447 | 1,582 | <issue_start>username_0: I'm reading rows from excel into a model , and excel returns the input such as "10%" or "20%" as "0.1" ,"0.2" **string** . What is the best way to convert that string into a **string** such as "20%" , "10%" and to avoid unnecessary conversions, in order not to lose on the performance ? So just to clarify i need to convert string to a string but the program is not letting me obviously . I could convert that string to double then convert that double to string with `ToString("#0.##%")`, but I would like to know if there is a faster way .
This is the code that reads row and formats excel columns into model props types
```
static T ReadRow(ExcelWorksheet worksheet, int rowNum)
{
var o = (T)Activator.CreateInstance(typeof(T));
int colNum = 1;
foreach (var p in typeof(T).GetProperties())
{
if (worksheet.Cells[rowNum, colNum].Value != null)
{
p.SetValue(o, Convert.ChangeType(worksheet.Cells[rowNum, colNum].Value, p.PropertyType));
}
colNum++;
}
return o;
```<issue_comment>username_1: The reason you are getting 10% as .01 is that the number is stored as .01 only and when reading excel you will get its actual stored value. You see it as 10% because its formatted as % in excel.
To read the percent: 10% as string '10%' you will have to format the string when reading.

```
string val = "0.2"; // for reference
string.Format("{0}%", Convert.ToDouble(val) * 100);

Array NSNumber Values
Writing Direction Constants
0 -> NSWritingDirectionLeftToRight | NSTextWritingDirectionEmbedding
1 -> NSWritingDirectionRightToLeft | NSTextWritingDirectionEmbedding
2 -> NSWritingDirectionLeftToRight | NSTextWritingDirectionOverride
3 -> NSWritingDirectionRightToLeft | NSTextWritingDirectionOverride
So, you can do that by this way
```
let myString = "Swift Attributed String"
let attr:[NSAttributedStringKey: Any] = [.foregroundColor: UIColor.blue, .writingDirection: [NSNumber(integerLiteral: 3)]]
let myAttrString = NSAttributedString(string: myString, attributes:attr)
self.label.attributedText = myAttrString

2018/03/20 | 1,090 | 3,625 | <issue_start>username_0: I am using Ajax to work with the openweather API. Everything works fine except for one thing.
I'm trying to make a button toggle between celsius and fahrenheit.
On the first click, the function converts the value to fahrenheit, but for some reason when you click the button again it doesn't convert it back to celsius.
I've found different solutions which work, but I would really like to avoid copy pasting and to figure out where's the error in my function's logic. I would appreciate your help on this.
Js Fiddle: <https://jsfiddle.net/m8w7gyxe/1/>
LE: Turns out that there were more errors than one :). Thank you everbody.
J.M.'s solution works great.
<https://jsfiddle.net/m8w7gyxe/31/>
```
℃ //celsius icon
let degree = '℃'; //celsius icon
let city = $('#searchInput');
const celsiusToFahrenheit = (celsius) => {
return (celsius \* 9 / 5 + 32);
}
$('#searchBtn').on('click', function() {
$.ajax({
url: 'https://api.openweathermap.org/data/2.5/weather?q=' + city.val() + '&units=metric&APPID=MYAPPIDHERE',
type: 'POST',
dataType: 'json',
success(response) {

},
error(jqXHR, status, errorThrown) {

}
});
});
function getResponse(response) {
$('#temperature').html(response.main.temp.toFixed() + ' ' + degree);
$('.toggleBtn').on('click', function() {
if (degree = '℃') { //if degree is celsius
degree = '℉'; //change degree to fahrenheit
$('#temperature').html(celsiusToFahrenheit(response.main.temp.toFixed()) + ' ' + degree);
}
if (degree = '℉') { // if degree is fahrenheit
degree = '℃'; // change degree to celsius
$('#temperature').html(response.main.temp.toFixed() + ' ' + degree);
console.log(degree); //℃
}
});
}
```<issue_comment>username_1: Several issues:
1. Yes, the handler for the `.on('click')` should be taken outside the response, as [username_2](https://stackoverflow.com/a/49383991/4770813) stated, you only need the values, not the response, to perform the conversions.
2. You say it works from Celsius to Fahrenheit but not the other way, I don't see a function to convert from Fahrenheit to Celsius.
3. `if (degree = '℃')` is not comparing, it's assigning, so always passes. Use `if (degree == '℃')` instead
4. You missed an important `else` in `else if (degree == '℉')`, without it both `if`s were being run.
Relevant edits here:
```
let fahrenheitToCelsius = (fahrenheit) => {
return ((fahrenheit -32) * 5/9).toFixed(2);
}
$('.toggleBtn').on('click',function() {
if (degree == '℃') { //if degree is celsius
degree = '℉'; //change degree to fahrenheit
$('#temperature').html(celsiusToFahrenheit(parseFloat($('#temperature').text())) + ' ' + degree);
}
else if (degree == '℉') { //if degree is fahrenheit
degree = '℃'; //change degree to celsius
$('#temperature').html(fahrenheitToCelsius(parseFloat($('#temperature').text())) + ' ' + degree);
}
});
```
try it and let me know: <https://jsfiddle.net/m8w7gyxe/26/>
Upvotes: 3 [selected_answer]<issue_comment>username_2: I think the problem is that you handler is being declared inside your "getResponse" function, which means when it is clicked it tries to use
```
response.main.temp.toFixed()
```
Which it can't because there is no response at that time. Try moving the handler outside of the getResponse, and instead of using the degrees from the response get it from what is currently on the page (You only need the number to convert back and forth, not the response)

2018/03/20 | 1,186 | 3,609 | <issue_start>username_0: Using SQL subquery, how do I get the total items and total revenue for each manager including his team?
Suppose I have this table items\_revenue with columns:
[](https://i.stack.imgur.com/LUHij.png)
All the managers (is\_manager=1) and their respective members are in the above table. Member1 is under Manager1, Member2 is under Manager2, and so on, but real data are in random arrangement.
I want my query to output the ff.:
[](https://i.stack.imgur.com/EKAX2.png)
This is related to [SQL query to get the subtotal of some rows](https://stackoverflow.com/questions/47525059/sql-query-to-get-the-subtotal-of-some-rows/47525135?noredirect=1#comment85758618_47525135) but I don't want to use the `CASE` expression. Thanks!
You can copy this to easily create the table:
```
DROP TABLE IF EXISTS items_revenue;
CREATE TABLE items_revenue (id int, is_manager int, manager_id int, name varchar(55), no_of_items int, revenue int);
INSERT INTO items_revenue (id, is_manager, manager_id, name, no_of_items, revenue)
VALUES
(1 , 1 , 0 , 'Manager1' , 621 , 833),
(2 , 1 , 0 , 'Manager2' , 458 , 627),
(3 , 1 , 0 , 'Manager3' , 872 , 1027 ),
(8 , 0 , 1 , 'Member1' , 1258 , 1582),
(9 , 0 , 2 , 'Member2' , 5340 , 8827),
(10 , 0 , 3 , 'Member3' , 3259 , 5124);
```<issue_comment>username_1: Use `union all` and aggreation:
```
select manager_id, sum(no_of_items) as no_of_items, sum(revenue) as revenue
from ((select ir.manager_id, ir.no_of_items, ir.revenue
from items_revenue ir
where ir.is_manager = 0
) union all
(select ir.id, ir.no_of_items, ir.revenue
from items_revenue ir
where ir.is_manager = 1
)
) irm
group by manager_id;
```
Note: This only handles direct reports in the table. This is the sample data that you provide. The problem is significantly different if you need all direct reports, so don't modify this question for that situation (ask another). If that is your need, then MySQL is not the best tool (unless you are using version 8), although you can solve it if you know the maximum depth.

2018/03/20 | 1,030 | 3,647 | <issue_start>username_0: I know (from the answers of [this question](https://stackoverflow.com/questions/10824347/does-sqlite3-compress-data)) that Sqlite by default doesn't enable compression. **Is it possible to enable it, or would this require another tool?** Here is the situation:
I need to add millions of rows in a Sqlite database. The table contains a `description` column (~500 char on average), and on average, each `description` is shared by, say, 40 rows, like this:
```
id name othercolumn description
1 azefds ... This description will be the same for probably 40 rows
2 tsdyug ... This description will be the same for probably 40 rows
...
40 wxcqds ... This description will be the same for probably 40 rows
41 azeyui ... This one is unique
42 uiuotr ... This one will be shared by 60 rows
43 poipud ... This one will be shared by 60 rows
...
101 iuotyp ... This one will be shared by 60 rows
102 blaxwx ... Same description for the next 10 rows
103 sdhfjk ... Same description for the next 10 rows
...
```
Question:
* Would you just insert rows like this, and enable a compression algorithm of the DB? **Pro: you don't have to deal with 2 tables, it's easier when querying.**
or
* Would you use 2 tables?
```
id name othercolumn descriptionid
1 azefds ... 1
2 tsdyug ... 1
...
40 wxcqds ... 1
41 azeyui ... 2
...
id description
1 This description will be the same for probably 40 rows
2 This one is unique
```
**Con: instead of the simple `select id, name, description from mytable` from solution #1, we have to use a complex way to retrieve this, involving 2 tables, and probably multiple queries?** Or maybe is it possible to do it without a complex query, but with a clever query with `union` or `merge` or anything like this?<issue_comment>username_1: Using multiple tables will not only prevent inconsistency, and take less space, but may also be faster, even if multiple/more complex queries are involved (precisely because it involves moving less data around). Which you should use depends on which of those characteristics are most important to you.
A query to retrieve the results when you have 2 tables would look something like this (which is really just a join between the two tables):
```
select table1.id, table1.name, table1.othercolumn, table2.description
from table1, table2
where table1.descriptionid=table2.id
```

First I convert the PDF to EPS and remove all text elements and images from the file like this
```
pdftocairo -f $page_number -l $page_number -eps $input - | sed '/BT/,/ET/ d' | sed '/^8 dict dup begin$/,/^Q$/ c Q' > $output
```
But how can I then check if any elements are written to the canvas?<issue_comment>username_1: What do you mean, exactly, by 'vector elements' ? Anything except an actual bitmap image ? Why do you care ? Perhaps if you explained what you want to achieve it would be easier to help you.
Note that the approach you are using is by no means guaranteed to work, there can easily be 'elements' in the file which won't be removed by your rather basic approach to finding image.
You could use Ghostscript; run the file to a bitmap and specify -dFILTERTEXT and -dFILTERIMAGES. Then examine the pixels fo the bitmap to see if any are non-white. If they are, then there was vector content i the file. You could probably use something like ImageMagick to count the colours and see if there's more than 1.
Or run the file to bitmap twice, once normally, and once with -dFILTERVECTOR. Compare the two bitmaps (MD5 on them would be sufficient). If there are no differences then there was no vector content.
Upvotes: 3 [selected_answer]<issue_comment>username_2: Any PDF that has vector elements will use at least one of the path painting operators. According to chapter 8 of the PDF standard, those are:
```
S, s, f, F, f*, B, B*, b, b*, n
```
Of course, since PDF files can be complex, you'll also need it in a standard form. You can do that using the `qpdf` program's `QDF` format. (`apt install qpdf` if you don't have it).
```
qpdf -qdf schedule.pdf - | egrep -m1 -q '\b[SsfFBbn]\*?$' && echo Yup
```
That'll print "Yup" if the file schedule.pdf has vector graphics in it.
---
Note: I think this will do the job for you, but it is not fool proof. It's possible to get false negatives if your PDF is loading vectors from an external file, embedding raw postscript, or doing some other trickiness. And, of course it can have false positives (for example, a file that draws a completely transparent, 0pt dot in white ink on a white background).

>
> But how can I then check if any elements are written to the canvas?

For this, the elements need to be part of a content stream that is referred to
in the `/Contents` member of the `Page` object.
If you read in all of the pdf objects, there will be a tree connecting all the content streams to the `Root` object declared in the trailer.
* Trailer : /Root is a reference to the Document Catalog object
* Document Catalog : /Pages is an array of Page objects or Pages nodes
* Page : /Contents is an array of references to Content Stream objects that draw the elements of the page
It is possible for there to be stray content stream objects that are not referenced in the Document tree. By traversing the Pages tree you could collect any and all actual content and then feed that result to one of the solutions from the other answers.

Amounts of shards depend on your partition key cardinality. For example, if your partition key cardinality is 2, then you have only two shards, and concurrency of your lambda is 2.
Remember you can't control a number of shards explicit.

So far I have done the following to troubleshoot this:
1. I tested the quickstart code from google and it worked.
2. I tried out oauth playground and I entered the same json data and it worked
I am not sure what exactly is the issue here. Scope is correct(worked in oauth playground), code seems to be correct(request worked in oauth playground). The only thing I can think of is request type?
I would appreciate any help.

Amounts of shards depend on your partition key cardinality. For example, if your partition key cardinality is 2, then you have only two shards, and concurrency of your lambda is 2.
Remember you can't control a number of shards explicit.

2018/03/20 | 1,348 | 4,239 | <issue_start>username_0: I've done this JavaScript calculation. [Live Preview](https://promehedi.com/projects/apps/diploma-cgpa-calculator/)
Everything is okay but the problem is, Once the calculation is done, the next time it shows NAN value. If you do not reload the page, then you can not calculation!
I want to repeat the calculation without reloading, how could it be?
Here Is my Simple Calculation:
```js
// get all data
var first = document.getElementById('first');
var second = document.getElementById('second');
var third = document.getElementById('third');
var four = document.getElementById('four');
var five = document.getElementById('five');
var six = document.getElementById('six');
var seven = document.getElementById('seven');
var eight = document.getElementById('eight');
var outPut = document.getElementById('result');
// Listen for Submit the form
document.getElementById('gpaInput').addEventListener('submit', outPutF);
function outPutF(e){
e.preventDefault();
// Calculation
first = first.value * 5 / 100;
second = second.value * 5 / 100;
third = third.value * 5 / 100;
four = four.value * 15 / 100;
five = five.value * 15 / 100;
six = six.value * 20 / 100;
seven = seven.value * 25 / 100;
eight = eight.value * 10 / 100;
var result = first + second + third + four + five + six + seven + eight;
// Reset the form
this.reset();
// Finally output the Calculation
outPut.innerHTML = 'Your CGPA: '+result;
// setTimeout(window.location.reload(true), 9000);
}
```
```css
input:focus, button:focus, select:focus {outline: none!important;box-shadow: none!important;}
#gpaInput .input-group {margin: 0.5em 0;}
#gpaInput .input-group-text { min-width: 95px;}
#result {display: block; width: 68%; text-align: center; margin-top: 25px; padding: 17px 0;}
.jumbotron {overflow: hidden;}
```

##### Complete The form!
```<issue_comment>username_1: You get NaN because you are replacing the reference to the element with its value , so on the second time it is not longer the element.
```
var first = document.getElementById('first'); //<-- element
first = first.value * 5 / 100; //<-- first replaced with a number
```
so than next time you call it
```
first = first.value * 5 / 100; //<-- first.value is undefined here since first is a number
```
So you need to rename your variables inside...
```
var nFirst = first.value * 5 / 100;
var nSecond = second.value * 5 / 100;
var nThird = third.value * 5 / 100;
var nFour = four.value * 15 / 100;
var nFive = five.value * 15 / 100;
var nSix = six.value * 20 / 100;
var nSeven = seven.value * 25 / 100;
var nEight = eight.value * 10 / 100;
var result = nFirst + nSecond + nThird + nFour + nFive + nSix + nSeven + nEight;

I am able to compile above line with Perl 5.8.8
can you please help me on this<issue_comment>username_1: I'm not surprised you're getting errors: the `fields` pragma expects a list of field names as parameters, and even if the inherited class provides something suitable through a call like that, it is far from clear whether the superior class is in scope at that point.
If you want more help then you must show a minimal code sample that reproduces the issue.

`Foo.pm`:
```
package Foo;

use warnings qw( all );
sub _praveen { qw( id ) }

```
from flight import Flight
```
Instead of:
```
from flight_genie.flight import Flight
```
If that doesn't work try to post your code so we can try to find the problem.

```
python dir_name/script.py
```
... then python will execute the file named `script.py` inside the folder `dir_name`. What will happen here is python program will go inside `dir_name` folder first and then run the script.
In your case if you type `python flight_genie/main.py`, it will go inside the folder `flight_genie` and will execute the file. Then python can't find a folder (actually the module) named `flight_genie` there because python program is already inside that folder. That's why you get this error.
So one way of fixing this issue is replacing all `import flight_genie.xxxx` with just `import xxxx`. (Also `from flight_genie.xxxx import yyyy` with `from xxxx import yyyy`)
But it is so time consuming if you have a large project. (And sometime it won't even work). So best way is to run the project as a whole module.
If you look at [here](https://www.python.org/dev/peps/pep-0338/) you can see how to run python modules as scripts. You just have to type the following command in console.
```
python -m flight_genie.main
```
ps: I assume that you have `python3` installed in windows and configured to run `python3` when you type `python` in command line.

Try to downgrade the Java version to Java 1.8.0-151. It should work.
There's an issue in glassfish 5 with Java 8 161, there's an [issue](https://github.com/javaee/glassfish/issues/22407) created, but no changes in nightly builds regarding the issue, I checked yesterday (19th march).
Upvotes: 4 [selected_answer]<issue_comment>username_2: The issue appears because Glassfish embeds native `sun.*` classes into `[glassfish5_home]/glassfish/modules/endorsed/grizzly-npn-bootstrap.jar`, so it conflicts with others classes included into `[JDK_HOME]/jre/lib/jsse.jar`
So edit the `grizzly-npn-bootstrap.jar` (make a copy before) file and remove the sun folder.

```

Upvotes: 3 <issue_comment>username_5: The changes in the security ciphers in java 1.8.0\_161 have broken the SSL function in the underlying Grizzly server of Glassfish 5,0. The last working java version was 1.8.0\_152
As of the moment of this writing i can confirm, that java 1.8.0\_202 works with Glassfish 5.1 (now maintained by and downloadable from Eclipse.org) The included grizzly-npn-bootstrap is ver 1.9.0. There is no need to delete or alter anything.

As a note, I have Glassfish 5.0 and Java `openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-8u232-b09-0ubuntu1~18.04.1-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)`
1. As mentioned by username_2, I copied the `grizzly-npn-bootstrap.jar` to another location as a backup.
2. I did the `jar -xvf grizzly-npn-bootstrap.jar` to see the exact classes and folder locations in the jar. Which gave me the following output:
```

```
3. Observe that the jar file contains 3 folders in the root level: **META-INF**, **org**, and **sun**. Again from username_2's answer we want to remove the `sun` folder.
4. I don't know a command line way to recreate a jar by specifying a folder to remove, so I did this command where I recreate the `grizzly-npn-bootstrap.jar` by just adding the **META-INF** and **org** folders: `jar -cvf grizzly-npn-bootstrap.jar META-INF/* org/*`
5. Subsequently if I do the `jar -xvf grizzly-npn-bootstrap.jar` command I get this output (notice no more **sun** folder listed):
```
cduran@cduran-VirtualBox:~/glassfish-5.0-web-profile/glassfish5/glassfish/modules/endorsed$ jar -xvf grizzly-npn-bootstrap.jar

```
6. Restart your glassfish.
After this I no longer get that error message the OP posted above:
>

This is a bug in openjdk up to 1.8.0\_242.
The SSLSessionImpl is not instantiated when it is used in SSLSessionEngine. It is used as a static class, however it is only a final class.
The issue has been fixed in 1.8.0\_252, so I recommend you to upgrade it to this version. Or switch to any build of Oracle jdk1.8.0, as there is no such bug in it.
Hope it helps.

2018/03/20 | 938 | 2,708 | <issue_start>username_0: I have read the [article](https://github.com/ethereum/EIPs/issues/165) abount ERC165 that is enable us to detect which interface is implemented in a contract.
However, I found that some ERC721 tokens are a little bit diffrent from others, like [cryptokitties](https://etherscan.io/address/0x06012c8cf97bead5deae237070f9587f8e7a266d) and [cryptohorse](http://www.cryptohorse.ch/sourceC.html).
Are these different ERC721 tokens are both detected as erc721 token by wallet application.
And how does erc721 support wallet detect the type of tokens.<issue_comment>username_1: In golang you can detect if a contract is a token by calling the EVM and checking the output, kind of like this:
```
// Getting token Decimals
input, err = erc20_token_abi.Pack("decimals")
if err!=nil {
utils.Fatalf("packing input for decimals failed: %v",err)
}
msg=types.NewMessage(fake_src_addr,addr,0,value,gas_limit,gas_price,input,false)
evm_ctx=core.NewEVMContext(msg,block_header,chain,nil)
ethvirmac=vm.NewEVM(evm_ctx,statedb,bconf,vm_cfg)
gp=new(core.GasPool).AddGas(math.MaxBig256)
ret,gas,failed,err=core.ApplyMessage(ethvirmac,msg,gp)
tok.decimals_found=false
if (failed) {
log.Info(fmt.Sprintf("vm err for decimals: %v, failed=%v",err,failed))
}
if err!=nil {
log.Info(fmt.Sprintf("getting 'decimals' caused error in vm: %v",err))
}
if !((err!=nil) || (failed)) {
int_output:=new(uint8)
err=erc20_token_abi.Unpack(int_output,"decimals",ret)
if err!=nil {
log.Info(fmt.Sprintf("Contract %v: can;t upack decimals: %v",hex.EncodeToString(addr.Bytes()),err))
} else {
tok.decimals=int32(*int_output)
tok.decimals_found=true
}
}
```
But if you don't want to get your hands dirty by working with the EVM directly, you can check event signatures:
```
erc20_approval_signature,_ = hex.DecodeString("8c5be1e5ebec7d5bd14f71427d1e84f3dd0314c0f7b2291e5b200ac8c7c3b925")
erc20_transfer_signature,_ = hex.DecodeString("ddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef")
```
These are located at event.Topics[0], so if Topics[0] matches to the above string the probability that the contract is ERC20 token is high. If you collect all the event of a contract, and derive a summary of what methods does it use, you can decide either it is a ERC20 or ERC721
Upvotes: 1 <issue_comment>username_2: Yes, some ERC-721 contracts do not follow the standard. The reason for most of them is because they were deployed before the ERC-721 standard was actually confirmed. One of these examples is CryptoKitties.
Use ERC-721 Validator that checks if a smart contract fully follows the ERC-721 standard: <https://erc721validator.org>
