Angular ng-repeat without html element | <p>I'm in trouble with a foreach that I need to do with Angular. </p>
<p>Thats's what I want to do :</p>
<pre><code><ul>
<div ng-repeat="g in groups">
<li ng-repeat="c in g.commands">{{c.text}}</li>
<li class="divider"></li>
</div>
</ul>
</code></pre>
<p>How can I do something like that, but in valid HTML structure ? (without a <code><div></code> between <code><ul></code> and <code><li></code>)</p>
<p>I see only one solution :</p>
<ul>
<li>Replace the <code><div></code> with a <code><ul></code> and make a lot of css rules to make it like it doesn't exists</li>
</ul>
<p>In addition, I use Angular 1.4.8.</p>
<p>Thanks !</p> | 1 |
Angular not getting data from FS.readFile with promises | <p>I am trying to use an Angular service to make a call to either use <code>fs.readFile</code> or <code>fs.writeFile</code> depending on type of button pressed in order to understand how node and angular promises interact. What I have is reading writing files, but does not send back read data, nor does it throw any errors for me to understand what has gone wrong. </p>
<pre><code>//HTML
<button ng-click="rw('write')">WRITE FILE</button>
<button ng-click="rw('read')">READ FILE</button>
//angular
angular.module('test', [])
.controller('ctrl', function($scope, RWService){
$scope.rw = function(type){
RWService.rw(type)
.then(
function(res){
console.log('success');
},
function(err){
console.log('error');
})
};
})
.service('RWService',['$http', '$q', function($http, $q){
this.rw = function(type){
var promise = $http.get('./rw/' + type);
var dfd = $q.defer();
promise.then(
function(successResponse){
dfd.resolve(successResponse);
},
function(errorResponse){
dfd.reject(errorResponse);
}
);
return dfd.promise;
};
}]);
//node
var fs = require('fs')
, async = require('async')
, Q = require('Q');
var dest = './file.txt';
var rw = {
write: function(data){
data = data.repeat(5);
return Q.nfcall(fs.writeFile, dest, data);

, read: function(data){
data = data.repeat(5);

Complex sorting for search in realm, union of multiple RealmResults | <p>I replaced sqlite with realm in my open source Linux Command Library project. Everything went fine so far, but now I'm facing a problem.</p>
<p>I'm using a RealmBaseAdapter to display all the commands in a ListView with an search interface. For a search the realm sniped below orders the results like this:</p>
<p>Query:
<strong>test</strong></p>
<p>result:</p>
<ul>
<li>l2<strong>test</strong> </li>
<li>rc<strong>test</strong></li>
<li><strong>test</strong></li>
<li><p><strong>test</strong>parm</p>
<pre><code>RealmResults<Command> commands = mRealm.where(Command.class).contains("name", query).findAll();
mAdapter.updateRealmResults(commands);
</code></pre></li>
</ul>
<p>With the old sqlite logic the order was like this:</p>
<p>result:</p>
<ul>
<li><strong>test</strong></li>
<li><strong>test</strong>parm</li>
<li>l2<strong>test</strong> </li>
<li>rc<strong>test</strong></li>
</ul>
<p><code>return getReadableDatabase().rawQuery("Select * from " + CommandsDBTableModel.TABLE_COMMANDS + " WHERE " + CommandsDBTableModel.COL_NAME + " LIKE '%" + query + "%' " + "ORDER BY " + CommandsDBTableModel.COL_NAME + " = '" + query + "' DESC," + CommandsDBTableModel.COL_NAME + " LIKE '" + query + "%' DESC", null);</code></p>
<p>Is it possible to realize it with realm too?

Optimization in Python: 'Var' object is not iterable | <p>I hope this is not a duplicate but i can't seem to find an specific answer to this problem. I'm pretty new to Python so it might be obvious but I can't seem to find my error.</p>
<p>So the problem is: I'm using gurobi to optimize a network-flow-model. But I have some trouble formulating the constraints because i have to iterate over 2 variables (I guess that is the problem).</p>
<p>Here is the code first: </p>
<pre><code>from gurobipy import *
import optimization
def beer(P, S, W, SP, g, d, b, c, m, n):
# Create new model
m = Model("Beer-Flow")
# Create variables
x = { (i,j,p) : m.addVar(name = "x[%s,%s,%s]" % (i,j,p)) for i,j in W for p in P }
y = { (i,j) : m.addVar(name = "y[%s,%s]" % (i,j)) for i,j in W }
# Integrate variables
m.update()
# Set objective
m.setObjective(quicksum(y[i,j] * d[i,j] * c for (i,j) in W ), GRB.MINIMIZE)
# Add constraints
for i in S:
m.addConstr((quicksum(x[i2,j,p])for p in P for (i2,j) in W if i2 == i ) - (quicksum(x[i2,j,p]for p in P for (i2,j) in W if j == i)) == b[i,p])
for i,j in W:
m.addConstr(m * y[i,j] >= (quicksum(x[i,j,p] * w[p] for p in P)))
m.addConstr(n * y[i,j] >= (quicksum(x[i,j,p] for p in P)))
return m
# Fill sets and parameters
P, g = multidict({"full" : 12, "empty" : 4 })
S = {"Brauerei","München","Stuttgart","Göttingen","Bielefeld","Magdeburg" }
W, d = multidict({("Brauerei", "München") : 558, ("Brauerei", "Stuttgart") : 437, ("Brauerei","Göttingen") : 142,

# Run optimization and print results
m.optimize()
optimization.print_result(m)
</code></pre>
<p>The part that is not working is: </p>
<pre><code>for i in S:
m.addConstr((quicksum(x[i2,j,p])for p in P for (i2,j) in W if i2 == i ) - (quicksum(x[i2,j,p]for p in P for (i2,j) in W if j == i)) == b[i,p])
</code></pre>
<p>The Error is: 'Var' type is not iterable
In Java for example I could get it done by two loops for p and i (tried it in Python, didn't work), but I have no clue how I can solve this problem with Python.</p>

Suitability/Performance of SQLite for large time-series data | <p>I've got time-series data that I'd like to store in a database of the format:</p>
<ul>
<li>group : string</li>
<li>date : date</li>
<li>val1 : number</li>
<li>val2 : number</li>
<li>... valN</li>
</ul>
<p>This database will be almost all reads. The searches will be for rows that belong to a group that is within a date range (e.g. group = XXX and date >= START and date <= END).</p>
<p>The data-set is big. Hundreds of millions of rows. Will SQLite be able to easily handle this kind of data? The appealing thing about SQLite is that it is serverless and I'd like to use it if I can.</p> | 1 |
Swift Wrap and Unwrap | <p>I'm a little confused about Swift Wrap and Unwrap! So lets say this is my code:</p>
<pre><code>var name:String? = "FirstName"
print(name)
</code></pre>
<p>Does the print function automatically unwrap the name which is optional? so I do not need to say
<code>print(name!)</code> in order to unwrap the name?
I guess what I am trying to understand is these two are equivalent for unwraping an optional variable?</p>
<p><code>print("name")</code> is just like saying <code>print ("name"!)</code></p>
<p>The other question I have is about nil.
is saying <code>var name:String? = "FirstName"</code> equivalent to saying <code>var name:String? = nil</code> . So does assigning a nil value wraps a variable?</p> | 1 |
What version of AXIS2 shipped with Websphere 8.5.5.2? | <p>I just want to know the inputs for below questions.</p>
<p>what version of AXIS2 will come with Websphere 8.5.5.2? </p>
<p>Where can i see the version details of AXIS2 jars shipped with WAS 8.5.5.2? </p>
<p>My code actually compiled with AXIS2 1.6.1 and deployed the same in WAS 8.5.5.2. I am getting below classcast exceptions. What could your suggestions to resolve this issue. I thought there is problem with different versions of axis2 while compiling and deploying. I am not able to know what version of axis2 shipped with websphere 8.5.5.2.</p>
<p><strong>Approaches I have used.</strong></p>
<p>1) Part of code which uses Axis was compiled against AXIS2 1.6.1 version and generated war was deployed in WAS 8.5.5.2 with no libraires in WAR. Got classNotFoundException for <strong>org.apache.axiom.util.stax.XMLStreamWriterUtils</strong>. Added org.apache.axis2.jar located in plugins in shared libraries and attached to my server war module level. Then class cast exception came.</p>
<p>2) Part of code which uses Axis was compiled against AXIS2 1.6.1 and generated war was deployed in WAS 8.5.5.2 with <strong>org.apache.axis2.jar</strong> under WEB-INF/libraires in WAR. Then class cast exception came.</p>

Run 'docker volume create' with Ansible? | <p>I have a Rails app I am deploying in Docker containers via Ansible. My app includes three containers so far:</p>
<ul>
<li>A Docker volume container (created with <code>docker volume create --name dbdata</code>)</li>
<li>A Postgres container (with <code>volumes_from</code> dbdata)</li>
<li>The Rails app container (which links to the postgres container)</li>
</ul>
<p>My deploy playbook is working, but I had to run the <code>docker volume create</code> command on the server via SSH. I'd love to do that via Ansible, so I could deploy a fresh instance of the app onto an empty container. </p>
<p>Is there a way to run <code>docker volume create</code> via Ansible, or is there some other way to do it? I checked the docs for the Ansible Docker module but it doesn't look like they support <code>volume create</code> yet. Unless I'm missing something?</p> | 1 |
Why object to json conversion using spring MVC doesn't work in this case? | <p>I need to execute this URL: <a href="http://localhost:8080/FitiProject/student" rel="nofollow">http://localhost:8080/FitiProject/student</a> and the response needs to be a json string containing the data of a <code>Student</code> object.</p>

asp.net core Oracle.DataAccess System.BadImageFormatException: Could not load file or assembly Oracle.DataAccess | <p>I've added Oracle.DataAccess as reference to asp.net core project.
I've only installed Oracle Data Provider for .Net when installed ODAC.
I would like to make a simple example with Dapper on the project.</p>
<pre><code>public class Program
{
const string connectionString = "xxxxx";
public static void Main(string[] args)
{
IDbConnection connection = new OracleConnection(connectionString);
string sql = "SELECT * FROM People WHERE Name='JOHN'";
var r = connection.Query<People>(sql);
}
}
</code></pre>
<p>The application wasn't running. I was getting this error below when I tried "dnx run" on the project folder.</p>
<blockquote>
<p>System.BadImageFormatException: Could not load file or assembly
'Oracle.DataAccess, Version=4.121.2.0, Culture=neutral,
PublicKeyToken=89b483f429c47342' or one of its dependencies. An
attempt was made to load a program with an incorrect format.</p>
</blockquote>
<p>If you get this message, probably, it means Oracle.DataAccess dll doesn't exist in the GAC.</p>
<ol>
<li><p>Open Command Line and go to bin folder under the odp.net e.g.
<pre><code>cd C:\oracle\product\12.1.0\client_x86\odp.net\bin\4</pre></code></p></li>
<li><p>Run this command below
<pre><code>
OraProvCfg.exe /action:gac /providerpath:C:\oracle\product\12.1.0\client_x86\odp.net\bin\4\Oracle.DataAccess.dll</pre></code></p></li>
</ol>
<p>After doing these steps I was able to run the project successfully.</p> | 1 |
Handling fatal error: unexpectedly found nil while unwrapping an Optional value when creating a date object from a date string | <p>I got a strange error when creating a date object.</p>

let startDateText:String = (data["startDate"] as AnyObject? as? String) ?? "";
print( startDateText ) ;
let startDate:NSDate! = dateFormatter.dateFromString(startDateText) ;
print( startDate ) ;

Symfony and Docker - Cache and Log dirs permissions | <p>I am trying to setup a Symfony project using docker but it always return errors related to permissions in "cache" directory.</p>

<p>This is the code that I can change the column title:</p>
<pre><code>table.getColumnModel().getColumn(0).setHeaderValue("Lecturersssss");
</code></pre>
<p>But the column title would not change until I hover the mouse on the <code>Lecturer</code> column header. </p>
<p>Even when i use <code>table.repaint()</code> after this code, it won't change.
Do you guys have any idea how can I solve this issue ?</p>

The xgboost package and the random forests regression | <p>The xgboost package allows to build a random forest (in fact, it chooses a random subset of columns to choose a variable for a split for the whole tree, not for a nod, as it is in a classical version of the algorithm, but it can be tolerated). But it seems that for regression only one tree from the forest (maybe, the last one built) is used. </p>

<p>Yes, of course, the default version of the xgboost random forest uses not a Gini score function but just the MSE; it can be changed easily. Also it is not correct to do such a validation and so on, so on. It does not affect a main problem. Regardless of which sets of parameters are being tried results are suprisingly bad compared with the randomForest implementation. This holds for another data sets as well.</p>
<p>Could anybody provide a hint on such strange behaviour? When it comes to the classification task the algorithm does work as expected.</p>
#
<p>Well, all trees are grown and all are used to make a prediction. You may check that using the parameter 'ntreelimit' for the 'predict' function. </p>
<p>The main problem remains: is the specific form of the Random Forest algorithm that is produced by the xgbbost package valid? </p>
<p>Cross-validation, parameter tunning and other crap have nothing to do with that -- every one may add necessary corrections to the code and see what happens.</p>
<p>You may specify the 'objective' option like this:</p>
<pre><code>mse = function(predict, dtrain)
{
real = getinfo(dtrain, 'label')
return(list(grad = 2 * (predict - real),
hess = rep(2, length(real))))
}
</code></pre>
<p>This provides that you use the MSE when choosing a variable for the split. Even after that, results are suprisingly bad compared to those of randomForest. </p>
<p>Maybe, the problem is of academical nature and concerns the way how a random subset of features to make a split is chosen. The classical implementation chooses a subset of features (the size is specified with 'mtry' for the randomForest package) for EVERY split separately and the xgboost implementation chooses one subset for a tree (specified with 'colsample_bytree'). </p>
<p>So this fine difference appears to be of great importance, at least for some types of datasets. It is interesting, indeed. </p> | 1 |
Calculate totals by reading from a text file in Python | <p>I am trying to write a program in python in which we have to add the numbers from different categories and sub-categories. The program is about a farmer's annual sale of produce from his farm. The text file from where we have to read from has 4 categories. The first category is the type of product for example Vegetables, Fruits, condiments. The second category tells us about the type of product we have, for example Potatoes, Apples, Hot Sauce. The third category tells us about the sales in 2014 and the fourth category tells us about the sales in 2015. In this program, we only have to calculate the totals from the 2015 numbers. The 2014 numbers are present in the text file but are irrelevant. </p>
<p>Here is how the text file looks like</p>
<pre><code>PRODUCT,CATEGORY,2014 Sales,2015 Sales
Vegetables,Potatoes,4455,5644
Vegetables,Tomatoes,5544,6547
Vegetables,Peas,987,1236
Vegetables,Carrots,7877,8766
Vegetables,Broccoli,5564,3498
Fruits,Apples,398,4233
Fruits,Grapes,1099,1234
Fruits,Pear,2342,3219
Fruits,Bananas,998,1235
Fruits,Peaches,1678,1875
Condiments,Peanut Butter,3500,3902
Condiments,Hot Sauce,1234,1560
Condiments,Jelly,346,544
Condiments,Spread,2334,5644
Condiments,Ketchup,3321,3655
Condiments,Olive Oil,3211,2344
</code></pre>
<p>What we are looking to do is to add the sales for 2015 by products and then the total sales for everything in 2015.</p>
<p>The output should look something like this in the written text file:</p>
<blockquote>
<p>Total sales for Vegetables in 2015 : {Insert total number here}</p>
<p>Total sales for Fruits in 2015 : {Insert total number here}</p>
<p>Total sales for Condiments in 2015 : {Insert total number here}</p>
<hr>
<p>Total sales for the farmer in 2015: {Insert total for all the
products sold in 2015}</p>
</blockquote>
<p>Along with that, it should also print the grand total on the Python run screen in the IDE along with the text file:</p>
<blockquote>
<p>Total sales for the farmer in 2015: {Insert total for all the
products sold in 2015}</p>
</blockquote>
<p>Here is my code. I am new to Python and reading and writing files so I can't really say if I am on the right track.</p>
<pre><code>PRODUCT_FILE = "products.txt"
REPORT_FILE = "report.txt"
def main():
#open the file
productFile = open(PRODUCT_FILE, "r")
reportFile = open(REPORT_FILE, "w")
# reading the file
proData = extractDataRecord(productFile)
product = proData[0]
category = proData[1]
salesLastYear = prodata[2]
salesThisYear = proData[3]
#computing
product = 0.0
product = salesThisYear
productFile.close()
reportFile.close()
def extractDataRecord(infile) :
line = infile.readline()
if line == "" :
return []
else :
parts = line.rsplit(",", 1)
parts[1] = int(parts[1])
return parts
# Start the program.

Div Button wrapper width? | <p>First post here.
I have shopping cart software called <strong>sellerdeck</strong> previously actinic. There is a lot of different code involved.</p>
<p>I have a button wrapper which has pre defined text inserted. I am trying to change the width of the button to a fixed width but pretty much everything I tried, from info I've found here and elsewhere, breaks the code and the button either disappears, does not function, or shrinks to about 10px.</p>
<p>Is it possible to set the width in the following code or is it likely that I will have to do it elsewhere within my software?</p>
<p>This code creates a small rectangle green button with white text that reads "Add to Cart" the text is pulled from code elsewhere in my software.</p>
<pre><code><div class="button-wrapper cart-button-wrapper">
<input value="<Actinic:Variable Name="CartButtonText"/>" name="_<Actinic:Variable Name="ProductID"/>" type="submit" class="button cart-button" onclick="return ValidateChoices('<actinic:variable name="ProductID" />');"/>

Insert new Documents or modify an array field of existing document | <p>Apologies if this is a re-post, but I wasn't able to quite get the query I want from the mongodb documentation examples. </p>
<p>Here's my issue. I am unable execute in a single query to either update an array_field of an existing document or add a new document and initialize the array_field with an initial value.</p>
<p>I can use findOne() with some conditional logic, and probably solve this, but I would think mongodb has an implementation of this use case</p>
<p>Here's the code so far:</p>
<pre><code>#data_json = JSON document to be added to collection
collection.update_one({"json_id":data_json["json_id"], "_dashbd_id_":dashboard_id},{{"$addToSet": {"array_field":keyword}},{"$setOnInsert":data_json}}, upsert=True)
</code></pre>
<p>I'm querying by the json_id, and _dashbd_id_ from my collection. If it exists, then I intend to add the "keyword" to the array_field. If it doesn't exist, create a new document as data_json which include array_field = [keyword]</p>

Is there any advantage of having a method as static? | <p>I am using <code>Webstorm</code> and I wrote a React component, my code looks like:</p>
<pre><code>async onDrop( banner, e ) {
banner.classList.remove( 'dragover' );
e.preventDefault();
const file = e.dataTransfer.files[ 0 ], reader = new FileReader();
const { dispatch } = this.props;
const result = await this.readFile( file, reader );
banner.style.background = `url( ${ result } ) no-repeat center`;
dispatch( addLayer( file ) );
return false;
}
@isImage( 0 )
readFile( file, reader ) {
reader.readAsDataURL( file );
return new Promise( function ( resolve, reject ) {
reader.onload = ( event ) => resolve( event.target.result );
reader.onerror = reject;
} );
}
onDragOver( banner ) {
banner.classList.add( 'dragover' );
return false;
}
</code></pre>
<p>Webstorm's code inspection suggest me that <code>Method can be static</code> for the <code>onDragOver</code> method. My question is:</p>
<p><strong>Are there any real benefit from having the method as static or this suggestion is somehow useless?</strong></p> | 1 |
Consuming a RESTapi stream with angular2 | <p>How is it possible to consume a "never-ending" data stream with angular2? I'm writing a little chat app with a server written in go and a client writting in angular2. For a push service I implemented an endpoint which will keep the connection up. A authorized user can connect to the message broker on <code>server.com:123/broker</code> with a GET request. Every time a new message for the user arrives its send to the broker in form of a json-object. How ever, when using the normale syntax I won't get any results (since the code waits for the connection to be closed as I suppose):</p>
<pre><code>return this._http.request(req).map( (res: Response) => {
return res.json();
}).subscrube( results => {
console.log("results arrived", results);
});
</code></pre>
<p>Consuming streams has a lot of advantages (like video streaming with a rest api, awesome). Is there a way to do this?</p>
<p>/edit: A little bit more information here:
I checked the http transaction and they look okay:</p>
<pre><code>GET /broker HTTP/1.1
User-Agent: curl/7.35.0
Host: mydomain.com:12345
Accept: */*
Authorization: Bearer [JWT]
</code></pre>
<p>The server ansers with the response header:</p>
<pre><code>HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
Date: Mon, 01 Feb 2016 11:16:45 GMT
Transfer-Encoding: chunked
</code></pre>
<p>[then the client is listening on this connection until the server pushes something into the stream</p>
<pre><code>ba
{"target":"56addcef7bec6d5785ee6945","payload": ...}
</code></pre>
<p>Seems correct so far. I can see the size of the chunk in hex (ba), the CRLF, the payload (json) and the final CRLF. So, when talking about HTTP Standard everything seems okay. However, my Angular2 won't fetch the chunks.</p> | 1 |

How to convert a positive signed int32 value to its negative one? | <p>I have try to write one logic is to convert an <code>int32</code> positive value to a corresponding negative one, i.e., <code>abs(negativeInt32) == positiveInt32</code>.</p>

Deferred function doesn't work as expected in IE with jQuery 1.12 | <p>I have 2 functions where I am trying to run one function and then the other. I have implemented this line in my code:</p>
<pre><code>function1().done(function2);
</code></pre>
<p>In function1 at the end I have placed this code:</p>
<pre><code>return $.Deferred().resolve();
</code></pre>
<p>This functionality works in both Firefox and Chrome, but does not seem to be working in Internet Explorer 11. I get no errors, but the functions are not running one after the other like it should be. Does anyone know why this is happening or know of a workaround/other way to do this that would work in all browsers?</p>
<p>I have been playing around with this example using Internet Explorer and experiencing the issue I mention above with it (the alert shows up before the text gets hidden, should happen the other way around):</p>
<pre><code><!DOCTYPE html>

function1 = function() {
$("p").hide("slow");
return $.Deferred().resolve();
}
function2 = function() {
alert("Text hidden now.");
}
$(document).ready(function() {
$("button").click(function() {
function1().done(function2);
});

Defining an int array in a class C++ | <p>Is there any way to dynamically (I think that's the right term) define an int array in a class, the size of which is a private member variable in that same class? For example:</p>
<pre><code>class Scene()
{
//public member functions
private:
int max;
int xcoords[max];
}
</code></pre>
<p>I've searched through other answered questions on here, but I haven't learned how to use vectors in class yet, which is what most responses suggest. Ideally, in my constructor for the class, I'd be passed an int max, with which I then initialize the xcoord array to have a size of max with entries all -1. </p> | 1 |
Missing Visual Studio Web Application publish targets | <p>I am missing the usual publish targets when publishing my c# web application.

Earlier, I noticed the same behavior using Enthought Canopy and also couldn't get scikit to work there either. As a result, I uninstalled every Python program and IDE I could find to try and clean my system before attempting Anaconda, as described above. I looked at many other posts and still could not get my system to work properly and suspect there's path, library, or version issue. </p> | 1 |
Good way to secure multiple Angular 2 components | <p>A common recommended way to secure Angular 2 component/routes seems to be to use <code>@CanActivate()</code>, like here:</p>
<p><a href="http://youknowriad.github.io/angular2-cookbooks/stateless-authentication.html" rel="nofollow">http://youknowriad.github.io/angular2-cookbooks/stateless-authentication.html</a></p>
<p>If you have only a few components this works fine, but is there a better way that would centralize all this? </p>
<p>Would having a common base class for each component work? (any examples on how to do this?). Could we have a custom <code>@CanActivate()</code>, something like <code>@ProtectMyApp()</code>? (examples?)</p>
<p>I'm basically trying to prevent having to copy+paste the same <code>@CanActivate()</code> code for each component.</p>
<p>(apologies if these questions do not make sense, still learning Angular)</p>
<p>Thanks</p> | 1 |

Python Pyinstaller 3.1 Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll | <p>Hello fellow programmers, so I am having a spot of trouble getting this python .exe to function properly.

Adding a property to a queryset in Django | <p>I'm creating a messaging system and part of what I want to do is based on whether the user is a sender or a receiver of a message, different CSS loads. I'm trying to achieve this by attaching a property to each message object that identifies this.</p>
<p>I have my message</p>
<pre><code>#models.py
class Message(models.Model):
def __unicode__(self):
return unicode(self.time_date)
message_from = models.ForeignKey(User, related_name="%(class)s_message_from")
message_to = models.ForeignKey(User, related_name="%(class)s_message_to")
message = models.TextField()
file = models.FileField(blank=True, null=True)
read = models.BooleanField(default=False)
time_date = models.DateTimeField(default=django.utils.timezone.now)
job = models.ForeignKey(Job, blank=True, null=True)
</code></pre>
<p>and my view to get the messages:</p>
<pre><code>def view_messages(request):
messages = Message.objects.filter(message_to=request.user, job_id=None).distinct('message_from')
messages_from_user_ids = messages.values_list('message_from', flat=True).distinct()
messages_from_user = User.objects.filter(id__in=messages_from_user_ids)
messages = Message.objects.filter(
Q(message_to=request.user) & Q(message_from_id=messages_from_user_ids[0]) & Q(job_id=None) | Q(
message_from_id=messages_from_user_ids[0]) & Q(
message_from_id=request.user) & Q(job_id=None)).order_by('time_date')
messages = Message.objects.annotate(foo='true') # error
return render(request, 'freelancestudent/general/messages.html', {'messages': messages,
'messages_from': messages_from_user})
</code></pre>
<p>What I was trying to achieve in the line commented error was to simply test <a href="https://docs.djangoproject.com/en/dev/topics/db/aggregation/" rel="noreferrer">annotations</a> by annotating the string <code>'true'</code> to every message object, accessible under <code>foo</code>. This gives me the error <code>'str' object has no attribute 'resolve_expression'</code>.</p>
<p>What I'm ultimately trying to achieve, in case I'm going about this the wrong way, is to check if the user is the sender. The idea i had of achieving it was to do something like this:</p>
<pre><code>for message in messages:
if message_from == request.user.id:
messages.annotate(sender=True)
</code></pre>
<p>Though, this isn't the right syntax. I'm not sure <code>annotate</code> is the right function, either. Any ideas?</p> | 1 |

Android Notification Large Icon Spec? | <p>Where can I find the right dimensions for the Large Icon for Android Notifications?</p>
<p>What do I want? I want a nice looking circle (some color) as a Large icon with a little envelop in it. And add a small icon with its own specs. </p>
<p>The small icon works all fine. But I have a question about the large icon. I searched for some hours now and couldn't find it! </p>
<p>What space can I use for Large Icon? How big is the space? And are there any specs about how big the little envelop in the Large icon should be?</p>
<p>Android Kitkat and above:</p>
<p>Large Icon (space I can fill): ?
Large Icon (how big must the little envelop be? any specs?): ?</p>
<p>Below Android KitKat:</p>
<p>I know that below Android KitKat the notifications are a bit different. But what are the specs here?</p>
<p>Large Icon (space I can fill): ?
Large Icon (how big must the little envelop be? any specs?): ?</p>
<p><a href="https://stackoverflow.com/questions/26973820/large-notification-icon-background">Large notification icon background</a>
The question is kinda the same as in this question. But this question didn't received a final answer. The accepted answer didn't convinced me because there was a discussion in the comments without a conclusion. </p> | 1 |

JQuery to find LI by text and UL by Class | <p>I am working with a list in SharePoint 2013 that creates an unordered list dynamically on mouseover (the List item ECB for those familiar with SharePoint). </p>
<p>The class name that is given has spaces added after at, 1 additional space for each menu item. I'm not sure if this affects the class property value in jquery so that is why I'm using the begins with notation. </p>
<p>I am needing to hide several menu items and I'm not getting alerts in my debug so I'm thinking my syntax is off.</p>
<p>I'm using this:</p>
<pre><code>if($('ul[class^="ms-core-menu-list"] li[text="View Item"]') ! == null) {
alert('F');
} else {
alert('no F');
}
</code></pre>
<p>I do not get alerts so either my syntax is wrong and I need assistance with that or the menu item isn't created when this code executes, in which case I'm wondering how it is possible to get at these menu items using jquery as I'm unable to deploy code in my environment.
I've looked at a number of blogs over the past few days but nothing recommended comes close to working for me.</p>

Comparing Python accelerators (Cython,Numba,f2py) to Numpy einsum | <p>I'm comparing Python accelerators (Numba, Cython, f2py) to simple For loops and Numpy's einsum for a particular problem (see below). So far Numpy is the fastest for this problem (factor 6x faster), but I wanted some feedback if there are additional optimizations I should try, or if I'm doing something wrong. This simple code is based on a larger code that has a number of these einsum calls, but no explicit for loops. I'm checking if any of these accelerators can do better. </p>
<p>Timings done with Python 2.7.9 on Mac OS X Yosemite, with gcc-5.3.0 installed (--with-fortran --without-multilib) from Homebrew. Also did %timeit calls; these single call timings are fairly accurate.</p>

Transaction returns E00027 but response code is 1 | <p>Using the Java API version 1.8.6 to commit a simple credit card payment transaction in live mode against a real gateway account.
TransactionResponse getResponseCode() returns 1 which is supposed to mean that the transaction succeeded.
But getErrors() includes an error E00027 that suggests that the transaction failed.
Did the transaction succeed or not?</p> | 1 |

How to insert pause in speech synthesis with grammatical hints | <p>I am writing a simple spelling test app using the HTML5 SpeechSynthesis API. The text I would like my app to say is something like the following: "The spelling word is Cat. The cat chased the dog.". </p>
<p>The API tends to race without much of a pause from the first sentence to the second. I wonder if there is a way to insert a bit of a pause between the 2 sentences. I realize I could create 2 separate utterances and use the pause() call. However the code would be simpler and less brittle if I could simply insert grammatical hints.</p>
<p>Normally in spoken English, one tends to pause a little longer between paragraphs. So I inserted a newline character in my text, but there was no noticeable impact.</p>
<p>I also tried using an ellipsis.</p>
<p>Is there any way to do this or am I stuck breaking everything into separate utterances?</p> | 1 |

Adding siblings to nodes in a family tree | <p>This <a href="http://bl.ocks.org/mbostock/2966094" rel="nofollow noreferrer">example</a> shows d3 being used to draw an ancestry chart.</p>
<p>I have been looking at chart having the ancestors, descendants and siblings as shown below. In the example John Doe, Mary Joe and Jacob Joes are siblings.</p>
<p>This is tree for John Doe. The tree for B1 Doe is collapsed. It will be complex if her tree is also shown in this chart. If that is done, her ancestor edges/links will cross with John Doe's. </p>
<p>Can a tree like this can be drawn with d3?</p>

Google API: refresh_token missing (access type = offline) | <p>I'm trying to connect my webapp to google drive. So I'm using PHP with official Github PHP client code [ <a href="https://github.com/google/google-api-php-client/tree/v1-master" rel="nofollow">https://github.com/google/google-api-php-client/tree/v1-master</a> ].</p>
<p>I followed the quickstart [ <a href="https://developers.google.com/drive/v2/web/quickstart/php" rel="nofollow">https://developers.google.com/drive/v2/web/quickstart/php</a> ] for v2, because PHP client is for v2 only.</p>
<p>Then I added a line to request offline access. [See <a href="https://developers.google.com/identity/protocols/OAuth2WebServer#offline]" rel="nofollow">https://developers.google.com/identity/protocols/OAuth2WebServer#offline]</a> </p>
<p>My app code, developed using Yii 1, but it's not important, is:</p>
<pre><code> $client = new Google_Client();
$client->setApplicationName("Google Drive Client");
$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
$client->setRedirectUri( Yii::app()->createAbsoluteUrl("site/googleApiLoginCallback") );
$client->setAuthConfigFile(CLIENT_SECRET_PATH);
$client->setAccessType('offline');
if (file_exists(CREDENTIALS_PATH)) {
$accessToken = file_get_contents(CREDENTIALS_PATH);
} else {
// Request authorization from the user.
$auth_url = $client->createAuthUrl();
header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
Yii::app()->end();
}
$client->setAccessToken($accessToken);
// Refresh the token if it's expired.
if ($client->isAccessTokenExpired()) {
$refresh_token = $client->getRefreshToken();
// CVarDumper::dump($refresh_token,2,true);
$client->refreshToken($refresh_token);
file_put_contents(CREDENTIALS_PATH, $client->getAccessToken());
}
return $client;
</code></pre>
<p>This is the code for handling the OAuth callback. I simply set the access token received, then redirect to the page.</p>
<pre><code>public function actionGoogleApiLoginCallback($code)
{
$client = new Google_Client();
$client->setApplicationName("Google Drive Client");
$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
$client->setRedirectUri( Yii::app()->createAbsoluteUrl("site/googleApiLoginCallback") );
$client->setAuthConfigFile(CLIENT_SECRET_PATH);
$client->setAccessType('offline');
$accessToken = $client->authenticate($code);
if(!file_exists(dirname(CREDENTIALS_PATH))) {
mkdir(dirname(CREDENTIALS_PATH), 0700, true);
}
file_put_contents(CREDENTIALS_PATH, $accessToken);
$preGoogleApiLoginRoute = Yii::app()->user->getState("preGoogleApiLoginRoute", null);
if ($preGoogleApiLoginRoute)
{
$this->redirect(array( $preGoogleApiLoginRoute ));
} else {
$this->redirect(array("site/index"));
}
}
</code></pre>
<p>When user the first time access the page, my webapp sucessfully redirect to Google Login; user do login, and Google redirect user to my website at <code>site/googleApiLoginCallback</code>. I set the received code as accessToken and redirect user to the page of webapp he come from. </p>
<p>It works.</p>
<p>BUT: After a while, when user came back to the page, tyhe token is expired. When it's executed the <code>$client->getRefreshToken()</code>, it returns a <code>null</code>, so <code>$client->refreshToken()</code> throw the following error because of missing refresh token</p>
<blockquote>
<p>Error refreshing the OAuth2 token, message: '{ "error" : "invalid_request", "error_description" : "Missing required parameter: refresh_token" }'</p>
</blockquote>
<p><strong>What am I missing or doing wrong?</strong></p>
<p>For reference: this is my json access token. As you can see I've not a field named 'refreshToken' as I expect</p>
<pre><code>{"access_token":"...hiddden...","token_type":"Bearer","expires_in":3600,"created":1453759023}

D3.JS: Multi-series line chart, show tooltip for all lines at date? | <p>I've created a multi-series line chart with tooltips. Please check it out at <a href="https://jsfiddle.net/rd1eoLq8/" rel="nofollow noreferrer">this JSFiddle</a>.</p>
<p>Currently, the tooltip works as expected: when you hover over a circle, it shows a tooltip with the data's value at that point.</p>
<pre><code>var tooltip = d3.tip()
.attr('class', 'tooltip')
.offset([-10, 0])
.html(function (d) {
return '<strong>Population ' + (d.date).getFullYear() + ':</strong> ' + format(d.population) + ' people';
});
svg.call(tooltip);
...
city.selectAll('.circle')
.data( function(d) { return(d. values); } )
.enter()
.append('svg:circle')
.attr('class', 'circle')
.attr('cx', function (d, i) {
return x(d.date);
})
.attr('cy', function (d, i) {
return y(d.population);
})
.attr('r', 5)
.on('mouseover', tooltip.show)
.on('mouseout', tooltip.hide)
</code></pre>
<p>However, I would like to open tooltips at all data points with that x-value. So it would look like this:</p>
<p><a href="https://i.stack.imgur.com/pX9id.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pX9id.png" alt="Tooltip idea"></a></p>
<p>Of course with the correct values for those points.</p>
<p>How could I modify my code to achieve this? Any help is greatly appreciated!</p> | 1 |

How to display validation errors on WooCommerce user registration before default errors | <p>I'm using the following filter & action to produce some custom validation errors on woocommerce registration process. </p>

Issue using try within R to catch errors with importing files | <p>I have a process in R in which I am importing a number of files in R. </p>
<p>Occasionally there are issues with some of the files, for example there isn't an EOF character present in the file that I'm reading in, so the read.table statement errors.</p>
<p>As there are a lot of files to process this is difficult to manage manually, so I would like to use some error trapping to alter the user of the issue and carry on with the other files. </p>
<p>I have tried using <code>try</code> and referenced the SOF post <a href="https://stackoverflow.com/questions/31214361/what-is-the-r-equivalent-for-excel-iferror" title="What is the R equivalent for Excel IFERROR?">What is the R equivalent for Excel IFERROR?</a></p>
<p>Below I would like to test the import then depending on the result either give some message to the user or actually import the file. </p>
<pre><code> mtry <- try(read.table("~/file_location/test_file.csv",
fill = TRUE,
stringsAsFactors = FALSE))
if (!inherits(mtry, "try-error")) {
read.table("~/file_location/test_file..csv",
fill = TRUE,
stringsAsFactors = FALSE)
} else {
message("File doesn't exist, please check")
}
</code></pre>
<p>The issue is that the <code>try()</code> statement is producing an error in the log which is what I'm trying to avoid.</p>

Spring JPA - deleting child element doesn't reflect in database table | <p>I'm having problems deleting the child element of a one-to-many relationship entity.
Here's a code snippet:</p>
<pre><code>@Override
@Transactional
public void deleteTask(UUID listId, UUID taskId) {
TaskList list = repo.findOne(listId);
System.out.println("Old List: " + list);
for(Task t : list.getTasks()) {
if(t.getId().toString().equals(taskId.toString())) {
System.out.println(list.getTasks().remove(t));
System.out.println("Task with id " + taskId + " deleted.");
}
}
System.out.println("New List: " + repo.save(list));
}
</code></pre>
<p>The Task class is this:</p>
<pre><code>@Entity(name = "task")
public class Task implements Serializable {
// Id and 3 fields
@ManyToOne
@JoinColumn(name="tasklist_id")
private TaskList parentList;
// 3 more fields
// Constructor
public Task() {}
//Getters and Setters
}
</code></pre>
<p>and the TaskList class is this:</p>
<pre><code>@Entity(name = "task_list")
public class TaskList implements Serializable {
// Id and two fields
@OneToMany(mappedBy="parentList", cascade={CascadeType.ALL})
private List<Task> tasks;
// Constructor
public TaskList() {}
}
</code></pre>
<p>The <code>Task</code> entity is the child, and even though the save() function returns the truncated <code>TaskList</code>, I can't get the changes to show in a separate query to the database. The number of tasks remains the same. However, deleting a list through <code>repo.delete(listId)</code> works fine with both the list and its tasks gone.</p>
<p>Here, <code>repo</code> is a repository corresponding to the parent <code>TaskList</code> class. All operations to the child <code>Task</code> class happen through a <code>@OneToMany({cascade=CascadeType.ALL})</code> relation.</p>
<p>For some reason, searching for all <code>TaskList</code>s using <code>repo.findAll()</code> also returns faulty results.</p>
<p>I'm obviously doing something fundamentally wrong. Please tell me what to do.</p> | 1 |

Spring JPA Multiple Relations with same entity | <p>I have the following relation:</p>

<p>I'm trying to map those relations using JPA in Spring Boot, but I'm having some trouble. These are the classes:</p>
<p><strong>Person:</strong></p>
<pre><code>public class Person {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
// Relations
@OneToOne
@JoinColumn(name = "child_id")
private PersonBirth birth;
@OneToMany
@JoinColumn(name = "mother_id")
private List<PersonBirth> motherOf;
@OneToMany
@JoinColumn(name = "father_id")
private List<PersonBirth> fatherOf;
}
</code></pre>
<p><strong>PersonBirth:</strong></p>
<pre><code>public class Birth {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "birth_date")
@JsonProperty(value = "birth_date")
private Long birthDate;
// Relations
@OneToOne
@JoinColumn(name = "child_id")
private Person child;
@ManyToOne
@JoinColumn(name = "mother_id")
private Person mother;
@ManyToOne
@JoinColumn(name = "father_id")
private Person father;

</code></pre>
<p>I'm trying to be able to get a <code>Pearson</code> and his <code>Birth</code> data including his <code>mother</code> and <code>father</code>. And also be able so get a <code>Person</code> with its children mapped by <code>fatherOf</code> or <code>motherOf</code>. But the way it is right now, it throws stackoverflow when I fetch a <code>Person</code> who is a mother, because it gets the <code>Birth</code> data, that contains the <code>child</code> data (so far what I want), that contains his <code>Birth</code> data, that contains his mother, that contains her children (and so on). I don't know if what I'm trying to do is possible using this structure or if I'll have to change it... Any suggestions are appreciated.</p> | 1 |

linking succeeds with arm-none-eabi-g++ but not arm-none-eabi-gcc | <p>I am using the Launchpad Arm compiler tools. Specifically, </p>

<p>(GNU Tools for ARM Embedded Processors) 5.2.1 20151202 (release) [ARM/embedded-5-branch revision 231848]</p>
<p>I have a simple program targeted at an STM32F103 processor that has no purpose except to prove that I can write the hardware and call a function from the math library. This is all it is:</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include "stm32f10x.h"
void hardwareTest(void){
// Turn on the clock for PortB
RCC->APB2ENR = RCC_APB2ENR_IOPBEN; // Turn on IO Port B
// Put PB0 into push pull 50 MHz mode
GPIOB->CRL = 0x03;
// Turn PB0 on
GPIOB->ODR = 1;
}
volatile int x; // force call to sqrt() later
int main(void) {
x = sqrt(100.0f);
x = sqrt(x);
hardwareTest();
return (x);
}
</code></pre>
<p>When I tried to build this, I got a linker error telling me that there is an undefined reference to sqrt. The build was done with arm-none-eabi-gcc.

<p>So can anyone tell me why the two compilers behave differently? What simple thing have I overlooked? How should I ensure proper linking with libm and others if I want to use arm-none-eabi-gcc?</p>
<p>I have looked at Freddie Chopin's makefiles but they are too complicated for me to unravel.</p> | 1 |
Batch file replace line in text file with new line | <p>I want to be able to replace a line in a properties file but i only know part of the line string at any one time</p>
<p>Heres the line i want to replace: <code>mb.datasource.password=ENC(8dF45fdD)</code></p>
<p>with this: <code>mb.datasource.password=apassword</code></p>
<p>What i have just now is this</p>
<pre><code>@echo off &setlocal
set "search=mb.datasource.password="
set "replace=mb.datasource.password=apassword"
set "textfile=mb.properties"
set "newfile=mb-new.properties"
(for /f "delims=" %%i in (%textfile%) do (
set "line=%%i"
setlocal enabledelayedexpansion
set "line=!line:%search%=%replace%!"
echo(!line!
endlocal
))>"%newfile%"
</code></pre>
<p>This ends up giving me mb.datasource.password=apassword=ENC(8fFdeUdK)</p>
<p>I can't just find the full string it needs to only be mb.datasource.password= because the part after the equals changes</p>
<p>Any help would be greatly appreciated?</p> | 1 |

ASP.Net Identity Force Logout From SQL | <p>I'm using the ASPNET Identity tables for my MVC 5 application. Each night we perform "maintenance" on our database. If we modify something under that user, I want to inactivate their current session so that the next action they perform in the web application will kick them back to the login screen. The authentication/authorization already is built into my application using AspNet.Identity. I just need a way to wake it up by setting a flag if it exists.</p>
<p>For example the ASPNETUsers table has an "Inactive" column, but that's too permanent. I'm looking for the "ThisGuyIsLoggedIn" column.</p>
<p>This was close to the same problem, but the answer was to manage it from within MVC, which is not an option.</p>

Autocomplete Textbox in C# and MVC | <p>Hi to all and thanks for your help,</p>
<p>I need to autocomplete a textbox with suggestions in C# and MVC.</p>
<p>The textbox in the view is:</p>
<pre><code><div class="col-lg-3 col-md-3 hidden-sm hidden-xs" style="margin-top:2%;">
<input type="text" class="formLocator" value="Milano" data-date-end-date="0d" id="textLocator" name="searchstring">
<h4 class="FormTextLocator">Where</h4>
</div>
<div class="hidden-lg hidden-md col-sm-3 col-xs-12" style="margin-top:2%;">
<input type="text" class="formLocator" value="Milano" data-date-end-date="0d" id="textLocator" name="searchstring">
<h4 class="FormTextLocator">Where</h4>
</div>
</code></pre>
<p>I have created a javascript code for this textbox:</p>
<pre><code>$(function ()
{
$("#textLocator").autocomplete(
{
source: "/Home/AutocompleteSuggestions",
minLength: 1,
select: function (event, ui)
{
if (ui.item)
{
$("#textLocator").val(ui.item.value);
$("form").submit();
}
}
});
});
</code></pre>
<p>And the controller associated is: </p>
<pre><code> public JsonResult AutocompleteSuggestions(string searchstring)
{
var db = new TocFruit();
var suggestions = from s in db.city select s.name;
var namelist = suggestions.Where(n => n.ToString().StartsWith(searchstring.ToLower()));
return Json(namelist, JsonRequestBehavior.AllowGet);
}
</code></pre>
<p>But all of this doesn't work but i don't understand what I'm doing wrong.</p>
<p>Thanks to all,</p>
