Ordering functions by Asymptotic Growth Rate | <p>List the following functions in non-descending order of asymptotic growth rate. If two or more functions have the same asymptotic growth rate then group them together.</p>
<p>g1(n) = n</p>
<p>g2(n) = n^3 +4n</p>
<p>g3(n) = 2n log(base 2) n </p>
<p>g4(n) = 2^n</p>
<p>g5(n) = 3 ^ (3 * log(base 3) n)</p>
<p>g6(n) = 10^n</p>
<p>I've been looking through several examples online but I have no idea how to do this, it just seems like a completely foreign concept to me. If anyone could help me, that would be much appreciated. how do I even calculate the growth rate?</p> | 1 |
sparse list of values using ranges | <p>is there a more terse way of writing</p>
<pre><code>listOf('a'..'z','A'..'Z').flatMap { it }
</code></pre>
<p>The idea here is to iterate over some values in a range, like the numbers from 1 through 100, skipping 21 through 24</p>
<pre><code>listOf(1..20, 25..100).flatMap { it }

Excel template migration from JXLS 1 to JXLS 2 | <p>With JXLS 1 it was possible to make replacements within an Excel template through a simple invocation to </p>
<pre><code>XLSTransformer.transformXLS(is,beans)
</code></pre>
<p>For example, we had bean objects which were organized something like this (not so nice, ok..:)):</p>
<pre><code>class Person{
private String name;
private String lastname;
private String tel;
private String gender;
private Integer count;
public Person(String name, String lastname, String telephone, String gender){
this.name = name;
this.lastname = lastname;
this.tel = telephone;
this.gender = gender;
this.count = null;
}
public Person(String gender, int count){
this.gender = gender;
this.count = count;
}
//getters
}
</code></pre>
<p>Now, given this template:</p>
<p><a href="https://i.stack.imgur.com/DCYRN.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DCYRN.jpg" alt="template"></a></p>
<p>and the following initialization:</p>
<pre><code>List<Person> p = Arrays.asList(
new Person(„Johnny“, „Cash“, „1394567“, „M“),
new Person(„Paul“, „Newman“, „234667“, „M“),
new Person(„M“,2),
new Person(„Jessica“, „Alba“, „134566“, „F“),
new Person(„F“,1)
);
Map<String, List<? extends Object>> beans = new HashMap<String, List<? extends Object>>();
beans.put(„persons“, p);
beans.put(„heading“, Arrays.asList(„This is the heading“));
</code></pre>
<p>a simple call to </p>
<pre><code>transformer.transformXLS(templateInputStream, beans);
</code></pre>
<p>would have done the trick and generated something like this:</p>
<p><a href="https://i.stack.imgur.com/tIlkR.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tIlkR.jpg" alt="generated XLS"></a></p>
<p>Now, I needed to migrate to JXLS 2 in order to use SXSSFWorkbook for very big XLSX files, but I couldn't succeed to translate the good old tags into their comment equivalent: in the online-doc I read that it's possible to combine more expression together, but for example something like <strong><em>jx:each</em></strong> followed by a <strong><em>jx:if</em></strong> which uses the loop’s variable would generate an expression EvaluationException.</p>
<p>Do you have any hints / examples which may help?</p>
<p>Thanks in advance!</p> | 1 |

How can I return different values from a mocked method using AngularJS and Karma? | <p>I'm testing ServiceA which uses ServiceB within itself. ServiceB has a method called getData() and sometimes it returns true and sometimes it returns false. Service A has different logic depending on whether ServiceB returns true or false and I need to test both situations. Currently, I'm mocking Service B like this:</p>
<pre><code>beforeEach(angular.mock.module('app', function ($provide) {
serviceB = {
getData: function () {
return true;
}
};
$provide.value('serviceB', serviceB);
}));
</code></pre>
<p>So how I can test what happens when serviceB returns true and then make anothter test to verify its behavior when it returns false? Can I create the mock within the it() methods rather than in beforeEach() so that I can have the mock return different values in different test methods?</p> | 1 |
Openpyxl - Apply Borders to Cells | <p>I am hoping someone can help me as I have been unable to figure this one out for myself unfortunately. </p>

How to deal with the missing data in stan? | <p>I am a newbie to stan and I am implementing the probabilistic matrix factorization model. </p>

<p>How should I represent the observable data in the <code>data</code> block and the missing data for prediction in the <code>parameter</code> block? </p>

<p>But the <code>jj[d]</code> should be a integer, denoting the id of <code>user</code>. And u[<code>int</code>] should be a <code>row_vector</code> has <code>k</code> factors and so is <code>i[ii[d]]</code>. The product of them should be a single real value, why stan said it was a <code>matrix</code>?</p> | 1 |
Bootstrap grid doesn't fit in my main container | <p>I'm sure of the fact that I'm doing something so wrong, I tried to solve that this morning.</p>
<p>Here's the deal, I'm trying to build a responsive HTML page, that will have the behaviour of the picture you see below : </p>
<p><a href="https://i.stack.imgur.com/38Rjv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/38Rjv.png" alt="enter image description here"></a></p>
<p>So I told myself, for the elements that have to be move like the elements below "Besoin d'un devis", etc, I will use a the boostrap grid, and use for that an WYSIWIG generator. But instead, when I try to resize the window here's what happens : </p>
<p><strong>Without resizing the window - Normal behaviour :</strong> </p>

<p>I uploaded a test version in the internet so you can see my problem.
<a href="http://test-stackoverflow.co.nf" rel="nofollow noreferrer">http://test-stackoverflow.co.nf</a></p>
<p>If you need the code, I will provide it. I just don't know a way to provide a whole "test website" and a case like this in stack.</p> | 1 |
Multiple interact() commands duplicate widgets in IPython | <p>I am using an IPython Jupyter notebook. In the following situation, I call a function using <code>interact()</code>, which in turns calls a second function again using <code>interact()</code>.</p>
<pre><code>def fun1(dataset_id):
dataset = read_dataset(dataset_id)
interact(fun2, data=dataset, var=(0,dataset.property,0.1))
def fun2(data, var):
# something
interact(fun1, dataset_id=(0,5,1))
</code></pre>
<p>When first running this, it display 2 slider widgets: one for <code>dataset_id</code>, and one for the variable <code>var</code>. But if I vary the <code>dataset_id</code> slider once, a second slider for <code>var</code> is added below the first <code>var</code> slider, so now I have 3 sliders in total. How can I avoid this?</p> | 1 |
Can't resolve dependency in Android Studio with jcenter | <p>Why my program hang on resolving dependency for appDebug in andorid studio? I can't resolve any library.</p>
<p>This is my root gradle file:</p>

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
</code></pre>

spark.ml StringIndexer throws 'Unseen label' on fit() | <p>I'm preparing a toy <code>spark.ml</code> example. <code>Spark version 1.6.0</code>, running on top of <code>Oracle JDK version 1.8.0_65</code>, pyspark, ipython notebook.</p>
<p>First, it hardly has anything to do with <a href="https://stackoverflow.com/questions/34681534/spark-ml-stringindexer-handling-unseen-labels">Spark, ML, StringIndexer: handling unseen labels</a>. The exception is thrown while fitting a pipeline to a dataset, not transforming it. And suppressing the exception might not be a solution here, since, I'm afraid, the dataset gets messed pretty bad in this case.</p>
<p>My dataset is about 800Mb uncompressed, so it might be hard to reproduce (smaller subsets seem to dodge this issue).</p>
<p>The dataset looks like this:</p>

<pre><code>org.apache.spark.SparkException: Unseen label: pl-PL.
</code></pre>
<p><strike>No idea, how <code>pl-PL</code> which is a value from <code>lang</code> column could have gotten mixed up in the <code>label</code> column, which is a <code>float</code>, not <code>string</code></strike> edited: some hasty coclusions, corrected thanks to @zero323</p>
<p>I've looked further into it and found, that <code>pl-PL</code> is a value from the testing part of the dataset, not training. So now I don't even know where to look for the culprit: it might easily be the <code>randomSplit</code> code, not <code>StringIndexer</code>, and who knows what else.</p>
<p>How do I investigate this?</p> | 1 |

Print Struct name in swift | <p>It is possible to know the name of a struct in swift ? I know this is possible for <code>class</code>:</p>

How to change background color for every other row in a ListView? | <p>Is there a way to change the the background color for every second row in a ListView? </p>
<p>I figured it should be doable with an if statement that recognises if it is a even or odd row and choose the style based on this. However, it does not seem possible to utilise this in React-Native. </p>
<p>My renderRow function looks like this:</p>
<pre><code>renderRow={(rowData) => {
return (
<TouchableHighlight
onPress={() => this.props.onSelectNote(rowData)}
style={styles.rowStyle}
underlayColor="#9E7CE3"
>
<Text style={styles.rowText}>{rowData.title}</Text>
</TouchableHighlight> )
}
}
</code></pre>
<p>As of now all rows will be styled according to rowStyle. How would it be possible to have different styles for different rows?</p> | 1 |
Minizinc search 2d array with constraints | <p>How could I select the smallest number from each row of a 2d array while making sure the same column can at most be selected twice
(in the following case, for row 1, column 5 is chosen; for row 2, column 5 is chosen while for row 3, column 5 can no longer be selected, so column 2 is selected as the min):
(Besides, in java, it is often that ArrayList is used to add and remove elements but how is it possible to do this in Minizinc using constraints)?</p>
<pre><code>int: m = 3;
int: n = 5;
array[1..m,1..n] of int: diffs = [|14,18,24,30,13
|10,12,18,24,7

Symfony 3 form - what is ::class and where is name? | <p>What does the <strong>::class</strong> used in the forms Symfony 3?</p>
<p>For example:</p>
<pre><code>->add('task', TextType::class)
</code></pre>
<p>or</p>
<pre><code>$form = $this->createForm(TaskType::class, $task);
</code></pre>
<p>Where can I read about the method <strong>::class</strong>?</p>
<p>In Symfony2 was:</p>
<pre><code>public function getName()
{
return 'appbundle_task';
}
</code></pre>
<p>And next in view I had prefix, for example:</p>
<pre><code><input id="appbundle_task_name" type="text" name="appbundle_task[name]">
</code></pre>
<p>What it is now the principle of generating names in inputs?</p> | 1 |
Laravel How to pass post data from one post method to another post method within the same controller? | <p>Suppose I have a search form which submit the search parameters to a post method with ajax, on that method I have returned the result in a view. Now on that view I have an option for user to select the range of record for printing in excel, so for this once again I need to submit the search parameters along with print settings to one another post method, on that method I need to search again for search parameters, and also limit the search for selected print ranges. So for this I need the same code block, but for avoiding that is it possible to call the search post method from within the print post method? If possible How can I do that? Or any other way?</p> | 1 |
How to get Flask/Gunicorn to handle concurrent requests for the same Route? | <p><strong>tl;dr</strong> A method decorated with <code>route</code> can't handle concurrent requests while Flask is served behind a gunicorn started with multiple workers and threads, while two different methods handle concurrent requests fine. Why is this the case, and how can the same route be served concurrently?</p>
<hr>
<p>I have this simple flask app:</p>
<pre><code>from flask import Flask, jsonify
import time
app = Flask(__name__)
@app.route('/foo')
def foo():
time.sleep(5)
return jsonify({'success': True}), 200
@app.route('/bar')
def bar():
time.sleep(5)
return jsonify({'success': False}), 200
</code></pre>
<p>If I run this via:</p>
<pre><code>gunicorn test:app -w 1 --threads 1
</code></pre>
<p>If I quickly open up <code>/bar</code> and <code>/foo</code> in two different tabs in a browser, whichever tab I hit enter on first will load in 5 seconds, and the second tab will load in 10 seconds. This makes sense because gunicorn is running one worker with one thread.</p>
<p>If I run this via either:</p>
<pre><code>gunicorn test:app -w 1 --threads 2
gunicorn test:app -w 2 --threads 1
</code></pre>
<p>In this case, opening up <code>/foo</code> and <code>/bar</code> in two different tabs both take 5 seconds. This makes sense, because gunicorn is running either 1 worker with two threads, or two workers with one thread each, and can serve up the two routes at the same time.</p>
<p><strong>However, If I open up two <code>/foo</code> at the same time, regardless of the gunicorn configuration, the second tab will always take 10 seconds.</strong></p>
<p>How can I get the same method decorated by <code>route</code> to serve concurrent requests?</p> | 1 |
Dynamic Button Icon Windows app | <p>I'm trying to do a pause/play button windows 10 app.</p>
<p>So far I know 3 ways to set the button using</p>
<p>button.context = "some segoe code" - works fine when I initialize it with the button but on the code to change the context the button appears as a bunch of squares</p>
<p>Button symbolicon - works fine initializing but no idea how to alter the symbolicon value outside of button declaration</p>
<p>button uri - only thing I could find online about button changing, but I don't have the button libraries that come in windows phone...</p>
<p>what is your recommendations so on clickrelease the button changes to either the pause or the play</p> | 1 |
Auto increment value in javascript class | <p>I'm trying to auto increment a properties value each time I instantiate a new instance of the class. This is what my class constructor looks (I abstracted it down just a bit): </p>
<pre><code>var Playlist = function(player, args){
var that = this;
this.id = ?; //Should auto increment
this.tracks = [];
this.ready = false;
this.unloaded = args.length;
this.callback = undefined;
this.onready = function(c){
that.callback = c;
};
this.add = function(tracks){
for(var i = 0; i < tracks.length; i++){
this.tracks.push(tracks[i]);
this.resolve(i);
}
};
this.resolve = function(i){
SC.resolve(that.tracks[i]).then(function(data){
that.tracks[i] = data;
if(that.unloaded > 0){
that.unloaded--;
if(that.unloaded === 0){
that.ready = true;
that.callback();
}
}
});
};
player.playlists.push(this);
return this.add(args);
};
var playlist1 = new Playlist(player, [url1,url2...]); //Should be ID 0
var playlist2 = new Playlist(player, [url1,url2...]); //Should be ID 1

<p>Now if I extend all my services with <code>BaseConnectivityService</code>; will it cause memory leak as that system will keep the services in memory for the purpose of notifying connectivity changes?</p>
<p>I have read <a href="https://groups.google.com/forum/#!topic/android-developers/Uf6gXIf5ntc" rel="nofollow">this thread</a>; which is somewhat similar question.
As Mark Murphy has written there :</p>
<blockquote>
<p>You will leak
memory, as your BroadcastReceiver will keep the component in RAM (even
if it was destroyed) until such time as Android terminates the
process.</p>
</blockquote>
<p>Is it be applicable for my scenario? If yes, what can be the good solution for avoiding memory leak and getting notified of network connectivity changes?</p> | 1 |
Appending to dict of lists adds value to every key | <p>I have a dictionary of empty lists with all keys declared at the beginning:</p>
<pre><code>>>> keys = ["k1", "k2", "k3"]
>>> d = dict.fromkeys(keys, [])
>>> d
{'k2': [], 'k3': [], 'k1': []}
</code></pre>
<p>When I try to add a coordinate pair (the list <code>["x1", "y1"]</code>) to one of the key's lists, it instead adds to all the keys' lists:</p>
<pre><code>>>> d["k1"].append(["x1", "y1"])
>>> d
{'k1': [['x1', 'y1']], 'k2': [['x1', 'y1']], 'k3': [['x1', 'y1']]}
</code></pre>
<p>What I was looking for was:</p>
<pre><code>>>> d
{'k1': [['x1', 'y1']], 'k3': [], 'k1': []}
</code></pre>

resize AVPlayerItem container view based on aspect ratio from video | <p>I have a container UIView called <code>videoView</code>. I add a AVPLayerLayer to that view. I do not know how to resize the <code>videoView</code> to be of the same proportions as the avplayer layer. Using <code>videoGravity</code> does not have the desired effect. </p>
<pre><code>AVPlayerItem* playerItem = [AVPlayerItem playerItemWithURL:path];
_videoPlayer = [[AVPlayer alloc] initWithPlayerItem:playerItem];
AVPlayerLayer *layer = [AVPlayerLayer layer];
[_avplayerLayer setPlayer:_videoPlayer];
[_avplayerLayer setBackgroundColor:[UIColor whiteColor].CGColor];
[_avplayerLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill];
[_avplayerLayer setFrame:_videoView.bounds];
[_videoView.layer addSublayer:_avplayerLayer];

<p>I am using autolayout, and my layout would accommodate a change in the height of _videoView. </p> | 1 |

Loop postgresql Function through Date Range | <p>I have a user defined function. <a href="https://stackoverflow.com/questions/14413203/writing-a-function-in-sql-to-loop-through-a-date-range-in-a-udf">This question</a> shows how to loop through dates. Using this approach, I tried this query:</p>
<pre><code>select myfun(a::date) from generate_series('2015-01-01'::date,'2016-01-27','1 day') s(a)
</code></pre>
<p>This doesn't quite work. What it returns is a single column of the form:</p>
<pre><code>(10101, "Sample", "test")
(10102, "Sample2", "test2")
</code></pre>
<p>When in reality there should be three columns. It merges them into one.</p>
<p>I noticed that this is the same behavior that you get in a vanilla query such as <code>select mytable</code> when I omit the asterisk. The above query doesn't have an asterisk in it, but adding one causes an error. </p> | 1 |
Get audio from HTML5 video | <p>I have been trying to figure out this for a week.
I have two completely different video tags with their respective audio. I also have one audio tag. At first, both muted attribute is set for both video tags. When I want to get video1 audio, I would like to get it audio source and assign it to the audio tag. Also do the same for video2. </p>
<p>Is this possible with Javascript? I have tried Web audio API but I'm lost. Please help.</p> | 1 |
How to change/rename specific attributes within a data frame column | <p>I need help changing/renaming attributes within columns of a data frame in R. I can get pretty close to what I need, but I haven't been able to work around the way that my "solution" changes the data. </p>
<p>Here's a dummy data frame:</p>
<pre><code>cols <- c("green", "green", "red", "blue", "black", "blue")
num <- c(1, 1, 2, 3, 4, 3)
df <- data.frame(cols, num)
df$cols <- as.character(df$cols)
> df
cols num
1 green 1
2 green 1
3 red 2
4 blue 3
5 black 4
6 blue 3
</code></pre>
<p>Let's say there was a mistake in my data and that all of my "green" attributes need to be "purple." Here's the bit of code I tried that was suggested over at the GIS StackExchange for a similar problem:</p>
<pre><code>df[df$cols == "green", ] <- "purple"
> df
cols num
1 purple purple
2 purple purple
3 red 2
4 blue 3
5 black 4
6 blue 3
</code></pre>
<p>As you can see, it does indeed change my green attributes to purple...but also changes its corresponding number column. With my real data frame, I have many other necessary columns that can't be changed like this. So how do I change attribute names within a column WITHOUT affecting other columns?</p> | 1 |

How to make the size of ellipse to get smaller and bigger in processing automatically | <p>I am creating something using classes in order to get used to them and I am trying to get the size of the ellipse I have drawn to get smaller and larger on its own so that it makes it look more interactive however I don't know what code to implement.</p>

How to use arrayformula to dynamically join strings in google spreadsheet? | <p>I use <code>Arrayformula()</code> to make my reports dynamic and easier to edit. For example, if I have a Column A with a list o number o blue balls in a set and a Column B with a list red balls in a set, on the cell C1 I can write <code>=ArrayFormula(add(A1:A,B1:B))</code> and in the Column C will have the total of balls in each set. It would be exactly the same as writing <code>=A1+B1</code> in cell C1 and dragging the formula down to the last row. <code>Arrayformula()</code> has some benefits, because it will work if some adds or removes rows from the sheet and also it makes the reports way more organized and easier to edit.</p>
<p>Since I´ve discovered <code>arrayformula()</code>, my life has changed, because of the fact that googleSheets expands the formula to other cells. It does not work every time, but the idea of expanding to other cells seems to be possible some way or another, <a href="https://stackoverflow.com/questions/35037640/how-to-make-a-range-repeat-n-times-in-google-spreadsheet/35039281#35039281">here is a good example</a> of a problem that was not resolved by <code>arrayformula()</code>, but has the same idea.</p>
<p>Keeping that idea in mind, imagine that on Column A there is a list of First Names and on Column B there is a list of Last names. On Column C I want to join this two string using a simples space. The way to do that would be in the cell C1 write <code>=join(" ",A1,B1)</code> and then drag down this formula. This method method however is prone to error since people can add and remove rows, deleting my formula. I want to use a formula that I can write in one single cell and it expands to other cells. I´ve tried <code>=arrayformula(join(" ",A1:A,B1:B))</code>, but it does not work. </p>
<p>Is that a way to do that using <code>=arrayformula()</code> or other native function?</p>
<p>I know I could write a script or custom formula to do that, but this is not my goal here.</p> | 1 |

<li><p>Redis is picking the correct config file i.e. <code>/etc/redis/redis.conf</code>.</p></li>

LINQ statement - WHERE clause for ENUM type | <p>I followed MSDN tutorial about filtering functionality in ASP.NET MVC web app > <a href="http://www.asp.net/mvc/overview/getting-started/getting-started-with-ef-using-mvc/sorting-filtering-and-paging-with-the-entity-framework-in-an-asp-net-mvc-application" rel="nofollow">http://www.asp.net/mvc/overview/getting-started/getting-started-with-ef-using-mvc/sorting-filtering-and-paging-with-the-entity-framework-in-an-asp-net-mvc-application</a></p>
<p>Unfortunately, I can't select an object which has an enum attriubute.</p>
<p>Used model is:</p>
<pre><code>public Bus()
{
public int BusID { get; set; }
public string RegNum { get; set; }
public Status? Status { get; set; }
public string Latitude { get; set; }
public string Longitude { get; set; }
}
</code></pre>
<p>where the enum type is:</p>
<pre><code>public enum Status
{
ON, OFF
}
</code></pre>
<p>According to the mentioned tutorial I implemented sorting method in BusController as shown below:</p>
<pre><code>public ViewResult Index(string searchString)
{
var buses = from b in db.Buses select b;
if (!String.IsNullOrEmpty(searchString))
{
buses = buses.Where(b =>
b.RegNum.ToUpper().Contains(searchString.ToUpper())
);
}
return View(buses.ToList());
}
</code></pre>
<p>it works fine for RegNum filtering, but I can't select the Bus for the given status by searchstring value.</p>
<p>b.Status.Equals(searchstring) doesn't work.</p>

InstallShield Limited Edition 2015 warning -6245 .Net Framework required | <p>I've created a project using VS2015, it uses .net framework v4.6.1.<br>
I'm now trying to create an install program for it using InstallShield Limited Edition. When I compile the install shield package I get the following warning :</p>
<p>ISEXP : warning -6245: One or more of the project's components contain .NET properties that require the .NET Framework. It is recommended that the release include the .NET Framework.</p>
<p>With the limited edition I don't see the option to include the .net framework, nor do I see a way to make the .net framework v4.6.1 a requirement.</p> | 1 |
Creating a record does not appear to persist to the test database, rspec, factory_girl_rails | <p>According to the <a href="https://github.com/thoughtbot/factory_girl/blob/master/GETTING_STARTED.md" rel="nofollow noreferrer">factory_girl_rails</a> documentation: here is the difference between the factory_girl <code>build()</code> and <code>create()</code> methods:</p>
<blockquote>
<p># Returns a User instance that's not saved</p>
<p>user = build(:user)</p>
<p># Returns a saved User instance</p>
<p>user = create(:user)</p>
</blockquote>
<p>I know the power of factories is that they make your test suite fast because it allows you to run tests without having to touch the database at all via the <code>build()</code> method. The <code>create()</code> method on the other hand does still touch the database because it persists the record to the database. </p>
<p>I am confused because when I put a break point within my test after using <code>create()</code></p>
<ul>
<li>The rails console says that the object is persisted to the database <em>(as expected)</em></li>
<li>The <code>test/test.log</code> show that the object was persisted to the database <em>(as expected)</em></li>
<li><p>But when I look at the table within the test database: It is not there <em>(not expected. I would expect to see the object within the database)</em></p>
<pre><code>#someApp/spec/models/user_spec.rb
RSpec.describe User, type: :model do
it "checks the age on the basic 'User' Factory " do
user = create(:user) # should create a user and persist it to the database
binding.pry
expect(user.age).to eq(28)
end
end
</code></pre></li>
</ul>
<p>Execution stops at the break point and the rails console opens up. I test for persistence and it returns true:</p>
<pre><code>user.persisted?
=> true
</code></pre>
<p>However, I look within my test database at the table, refresh the table, and yet still no record is shown:</p>
<p><a href="https://i.stack.imgur.com/wKhzK.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wKhzK.png" alt="record does not display in table"></a></p>
<p>What am I missing? I thought that when you use <code>create()</code> the record will be persisted to the database. Does it actually not save to the database at all?</p> | 1 |
Azure Data Factory Copy Activity - Can column mappings be composites or use a Templating function? | <p>When using a Data Factory Copy Activity to take delimited text files from Blob Storage to Table Storage, I am able to specify the input and output schemas and the relevant one-to-one Column Mappings.</p>
<p>It is possible to concatenate or format one or more columns (with $$Text.Format perhaps?) in the source schema and map these to a single column in the destination? </p>
<p>If possible, this would be especially useful if I can also set the Partition Key using a similar approach (a composite key taken from 2 or more source column values or better still, the SliceStart plus a concatenated source column value).</p> | 1 |
Define Type of Immutable Map With Builder | <p>I am trying to make a <code>Map<BooleanSupplier, List<String>></code> as part of my flow I make the suppliers and then try to use an immutable map builder.</p>
<p>Something like: </p>
<pre><code> //Build up BooleanSuppliers
Map<BooleanSupplier, List<String>> bsList = ImmutableMap.builder()
.put(bs1, Collections.singletonList("bs1string"))
.put(bs2, Arrays.asList("bs4","bs6"))
....
.build();
</code></pre>
<p>The problem is that intellij says that the types are not convertible even when I do an explicit cast because the ImmutableMap is of type <code><Object, Object></code>. Is there a way to explicitly cast or initialize the immutable map builder to be of type <code>ImmutableMap<BooleanSupplier, List<String>></code>?</p> | 1 |
SQLAlchemy for Python, 'Query' object has no attribute 'fetchone' | <p>I'm working on a database-centric project with a fellow programmer. We have the following code for retrieving information from our database:</p>
<pre><code># create connection to database
engine = create_engine(URL(**DATABASE))
Session = sessionmaker(bind=engine)
session = Session()
# construct query
query = session.query(MediaText.line_number, MediaText.start_time_stamp, MediaText.end_time_stamp).\
filter(MediaText.oclc_id == oclcId)
# get info about first line to snapshot
line_to_snapshot = query.fetchone()
</code></pre>
<p>When I try to run the code, I get the following error:</p>
<blockquote>
<p>AttributeError: 'Query' object has no attribute 'fetchone'</p>
</blockquote>
<p>What's confusing is that my partner can run the code just fine. We're both running Python 3.4 and have version 1.0.9 of the SQLAlchemy library on our systems. Does anyone know what could be going wrong here?</p> | 1 |
Prism Custom Confirmation Interaction | <p>I created a custom confirmation window in an app with Prism Unity, WPF & Mvvm. I need help with the notifications that need to be sent back to the viewmodel. I have this in the detail record view, let's call it MyDetailView.</p>
<pre><code><!-- Custom Confirmation Window -->
<ie:Interaction.Triggers>
<interactionRequest:InteractionRequestTrigger
SourceObject="{Binding ConfirmationRequest, Mode=TwoWay}">
<mycontrols:PopupWindowAction1 IsModal="True"/>
</interactionRequest:InteractionRequestTrigger>
</ie:Interaction.Triggers>
</code></pre>
<p>As shown above, I made the interaction Mode=TwoWay so that the confirmation popup window can send back the button click result for the OK or Cancel button. The confirmation window appears as it should, but I don't know how to send the button click result back to my viewmodel, say MyDetailViewModel. That is the main question.</p>
<p>EDIT: This is MyDetailViewMmodel method that raises the InteractionRequest.</p>
<pre><code>private void RaiseConfirmation()
{ConfirmationRequest
.Raise(new Confirmation()
{
Title = "Confirmation Popup",
Content = "Save Changes?"
}, c =>{if (c.Confirmed)
{ UoW.AdrTypeRos.Submit();}
</code></pre>
<p>This is the PopupWindowAction1 class. Part of the answer to the question may be how do I implement the Notification and FinishedInteraction methods.</p>
<pre><code>class PopupWindowAction1 : PopupWindowAction, IInteractionRequestAware
{
protected override Window GetWindow(INotification notification)
{ // custom metrowindow using mahapps
MetroWindow wrapperWindow = new ConfirmWindow1();
wrapperWindow.DataContext = notification;
wrapperWindow.Title = notification.Title;
this.PrepareContentForWindow(notification, wrapperWindow);
return wrapperWindow;
}
public INotification Notification
{
get { throw new NotImplementedException(); }
set { throw new NotImplementedException(); }
}
public Action FinishInteraction
{
get { throw new NotImplementedException(); }
set { throw new NotImplementedException(); }
}
}
</code></pre>
<p>Is there some interaction I need to put in my ConfirmWindow1, something like this?</p>
<pre><code><i:Interaction.Triggers>
<i:EventTrigger EventName="PreviewMouseLeftButtonUp">
<ei:CallMethodAction
TargetObject="{Binding RelativeSource={RelativeSource AncestorType=UserControl},
Path=DataContext}"
MethodName="DataContext.ValidateConfirm"/>
</i:EventTrigger>
</i:Interaction.Triggers>
</code></pre>
<p>Do I even need to do that type of interaction within the button? If so, how do I code it needs so that it corresponds to the particular viewmodel that invoked the interaction. Any suggestions? Thank you.</p> | 1 |

Docker, Django and Selenium - Selenium unable to connect | <p>I have Docker configured to run Postgres and Django using docker-compose.yml and it is working fine.</p>
<p>The trouble I am having is with Selenium not being able to connect to the Django liveserver.</p>
<p>Now it makes sense (to me at least) that django has to access selenium to control the browser and selenium has to access django to access the server.</p>
<p>I have tried using the docker 'ambassador' pattern using the following configuration for docker-compose.yml from here: <a href="https://github.com/docker/compose/issues/666" rel="nofollow">https://github.com/docker/compose/issues/666</a></p>

<p>When I check <a href="http://DOCKER-MACHINE-IP:4444/wd/hub/static/resource/hub.html" rel="nofollow">http://DOCKER-MACHINE-IP:4444/wd/hub/static/resource/hub.html</a>
I can see that firefox starts, but all the tests fail as firefox is unable to connect to django</p>
<pre><code>'Firefox can't establish a connection to the server at localhost:8081'
</code></pre>
<p>I also tried this solution here <a href="https://github.com/docker/compose/issues/1991" rel="nofollow">https://github.com/docker/compose/issues/1991</a>
however this is not working cause I can't get django to connect to postgis and selenium at the same time</p>
<pre><code>'django.db.utils.OperationalError: could not translate host name "postgis" to address: Name or service not known'
</code></pre>
<p>I tried using the networking feature as listed below </p>
<pre><code>postgis:
dockerfile: ./docker/postgis/Dockerfile

</code></pre>
<p>but the result is the same</p>
<pre><code>'Firefox can't establish a connection to the server at localhost:8081'
</code></pre>
<p>So how can I get selenium to connect to django?</p>
<p>I have been playing around with this for days - would really appreciate any help.</p>
<p><strong>More Info</strong></p>
<p>Another weird thing is that when the testserver is running <strong>not</strong> using docker (using my old config of virtualenv etc.) if I run ./manage.py test foo I can access the server through any browser at <a href="http://localhost:8081" rel="nofollow">http://localhost:8081</a> and get served up webpages, but I can't access the test server when I run the equivalent command if I run it under docker. This is weird cause I am mapping port 8081:8081 - is this related?</p>

Launch an activity in main app from an Android Library Module | <p>I am building my first library module that I am planning on filling with reusable code for multiple projects. My first roadblock is that I need to be able to launch an activity in the main app from the library module.</p>
<p>For example, I have a splash screen activity. It runs for 2 seconds, then launches the main activity. I believe that I can reuse this splash screen activity, and I want to put it in my library module. However, I am unsure how to launch the main activity from the library.</p>
<p>Mainfest in main app setup: </p>
<pre><code><activity
android:name="com.example.myLibraryModule.SplashScreen"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</code></pre>
<p>The manifest launches the splash screen which currently resides in my library module.</p>
<p>Since the library is a dependency of the main application and not the other way around, I am not sure how to go about launching the <code>MainActivity</code> from my <code>SplashScreenActivity</code>. It's not as easy as:</p>
<pre><code>Intent i = new intent(this, MainActivity.class);
startActivity(i);

Having my bundle in a non-root folder | <p>I'm creating a web-site with <code>react</code> using <code>webpack</code>.</p>
<p>Currently my <code>webpack.config.js</code> looks like this:</p>
<pre><code>var path = require('path');
var webpack = require('webpack');
module.exports = {
entry: './scripts/main.js',
output: {
path: __dirname,
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
query:{
presets: ['es2015', 'react']
}
}
]
}
}
</code></pre>
<p>Then I start the dev server using <code>webpack-dev-server --progress --colors</code> and whenever I change a javascript file, my web-page refreshes, and everything seems to be working fine. However, I would like my <code>bundle.js</code> file to reside in another folder than the root folder. I therefore changed the line <code>path: __dirname,</code> to <code>path: __dirname + '/dist',</code>.</p>
<p>Now, when I make a change to the script files, the bundle does not get automatically updated, but if I manually run the <code>webpack</code> command it gets built. So my question is: what is the proper way to get my <code>bundle.js</code>file to be put in the <code>dist</code> folder and still get the <code>webpack-dev-server</code> to automatically update when I do a change to my scripts?</p> | 1 |

Why does sockJS add a '/info' to a given websocket url path | <p>I want to open a websocket port with a "webapp/socket.do" path. When I use SockJS and try to initiate the call by code</p>
<pre><code> var socket = new SockJS('/webapp/socket.do');
stompClient = Stomp.over(socket);
stompClient.connect({}, ...
</code></pre>
<p>SockJS will by default add a "/info" to the end of the given path. I want to know why? Can this be changed or prevented? </p>
<p>When using this with Spring MVC and have url pattern mappings to DispatcherServlet like <code>< url-pattern >*.do</url-pattern></code>, this will return a 404 error. it is blocked because of the "/info" string added by sockJS to the given url.</p>
<p>Spring web.xml servlet mapping code:</p>
<pre><code><servlet-mapping>
<servlet-name>dispatch-servlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</code></pre>
<p>Does any know what sockJS is trying there and why?</p> | 1 |
YoutubeData API V3 - Error 400: required parameter - part | <p>I'm trying to fetch data from Youtube API using jQuery and Ajax GET request with the required parameter, including "part".
The GET request is ok (code 200), however when I see the data I'm getting an error 400 "required parameter: part".
Could anyone give me some tip to overcome this issue?
This is part of my jQuery and the result of the ajax request is right below.</p>
<pre><code>$(document).ready(function(){
console.log('doc ok');
$('#tag-search').submit(function(){
var search_term = {
q: "test"
};
search(search_term);
});
});
function search(search_term) {
console.log('searching ...');
console.dir(search_term);
var search_term = '';
var desireSearch = $ ('#tag').val();
var channelName = 'Iron_Maiden';

How to upload a file to Azure Storage with WinSCP (SFTP)? | <p>theI have a C# service using WinSCP which reliably uploads files to any SFTP server. I'd like to use it to connect to MS Azure Storage and <strong>upload</strong> files there using the same SFTP protocol. <strong><em>Please note I am not looking to use any other protocol (i.e.: FTP, FTPS, HTTPS, etc.) as well as I am not looking to SFTP files [out] of the Azure Storage.</em></strong> There are plenty of examples of how to use WinSCP when SFTP [out] from Azure Storage but none of them covers how to SFTP [in].</p>
<p>I have searched Stack Overflow knowledge base, Azure Help Documentation (<a href="https://azure.microsoft.com/en-us/documentation/articles/storage-dotnet-how-to-use-blobs/" rel="nofollow noreferrer">https://azure.microsoft.com/en-us/documentation/articles/storage-dotnet-how-to-use-blobs/</a>) as well as WinSCP docs (<a href="http://winscp.net/eng/docs/guide_microsoft_azure_webjob_sftp" rel="nofollow noreferrer">http://winscp.net/eng/docs/guide_microsoft_azure_webjob_sftp</a>, etc.).</p>
<p>Any help appreciated. Thanks.</p>
<p><strong>UPDATE: 2016-01-29</strong>
So... from what I understand so far, it is not possible to upload files to Azure Storage using SFTP protocol. MS Azure does not support this feature. Can anybody confirm that for me please? </p>
<p><strong>UPDATE: 2016-02-01</strong>
The similar Q/A here (<a href="https://stackoverflow.com/questions/21711592/facading-azure-storage-blob-with-sftp-service">Facading Azure storage blob with sFTP service</a>) does not answer my question because:
a) all answers are suggesting a theoretical workarounds using VM or other substitutes
b) it does not provide clear answer to my question</p>
<p><strong>This should not be so difficult to answer.</strong> If the SFTP is not supported then the answer is: <strong><em>"SFTP is not supported in Azure"</em></strong>. If the SFTP protocol is supported, then please provide more details about the settings, methods, and/or C# example. My question is clearly defined on purpose so others with the same need can quickly find the answer without wasting their time.</p> | 1 |

How to open a child window from the main window | <p>My question is tough to explain but I am trying my best. Please help me in this regard.</p>
<p>I designed a gui in QtDesigner and converted .ui files into .py e.g. main_window.py. Now in order to avoid changing in main_window.py I created another class for listeners.</p>
<pre><code>class Main():
window = None
app = None
def __init__(self):
self.launch()
self.attach_listener()
self.execute()
''' Launch GUI '''
def launch(self):
self.app = QtGui.QApplication(sys.argv)
self.window = Ui_MainWindow()
self.window.show()
''' Execute Window '''
def execute(self):
sys.exit(self.app.exec_())
''' Attach Listeners '''
def attach_listener(self):
self.window.add_button.clicked.connect(self.add_listener)
self.window.delete_button.clicked.connect(self.delete_listener)
self.window.update_button.clicked.connect(self.update_listener)
self.window.connect(self.window.combo_box, QtCore.SIGNAL('activated(QString)'), self.logout_listener)
</code></pre>
<p>I have another child_window.py with same structure, but I can't open that window from this one because of QApplication. I searched for the answer but couldn't apply on my code. Those answers were applicable when class was extending from QtGui.QMainWindow or QtGui.QWidget, but my scenario is different.</p> | 1 |

How does C3js decide the y axis range | <p>I'm working with C3.js to build graphs for my JSON data. However, I do not understand what decides the Y-axis ranges on the graph.

Please take a look at the image below.</p>
<p><a href="https://i.stack.imgur.com/Kk9fM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Kk9fM.png" alt="enter image description here"></a></p>

Azure Service Fabric Multi-Tenancy | <p>I'm trying to get a little follow up to this question that's already been answered...</p>
<p><a href="https://stackoverflow.com/questions/34616020/service-fabric-multi-tenant">Service Fabric multi-tenant</a></p>
<p>If I were to setup my tenants as Azure Service Fabric Stateless Services (they'll get their state out-of-band), how can I put more than one tenant on each node in the cluster? In testing, it seems that Service Fabric gags if you try and make your instance count greater than the node count.</p>
<p>These tenants are very lightweight, so I should be able to run dozens of them on each node (we will have hundreds overall), and I don't want to have to do a node for each one. Specifically, the tenants are more-or-less just opening a long-polling HTTP connection to an external customer service and streaming that data back into our system - so there's no public endpoints in play here. I just need the ability to spin up a lot of these workers that'll each open up their own long-polling connection.</p>
<p>Can somebody point me in the right direction?</p>
<p>FYI, I've explained a little bit more here... <a href="https://social.msdn.microsoft.com/Forums/en-US/efd172e2-0783-489b-b3ab-ec62fb7b8ee4/multiple-instances-per-node?forum=AzureServiceFabric" rel="nofollow noreferrer">https://social.msdn.microsoft.com/Forums/en-US/efd172e2-0783-489b-b3ab-ec62fb7b8ee4/multiple-instances-per-node?forum=AzureServiceFabric</a></p>

Maven cannot find opencsv csv parser | <p>I've come across one problem with maven and opencsv</p>

Sequelize BulkCreate Error | <p>I am trying to figure out how to use the bulkCreate method with my jQuery field values.

Eager load hasMany & belongsTo (circular reference/infinite loop) | <p><strong>UPDATE (SOLUTION)</strong></p>
<ul>
<li>If you need <code>->user</code> relationship from one of the <code>$image</code> inside <code>$user->images</code>, then <code>$user</code> variable is already available cause you loaded the <code>->images</code> from it!</li>
<li>Don't use <code>protected $with</code> Eloquent property. It's an anti-pattern.</li>
<li>Instead explicitly eager load relationships on-demand from where/when it's needed (<em>Note</em>: it should not prevent you to keep things DRY!)</li>
<li>If you really need/want to, see @nicksonyap answer. It does the trick (I believe – not tested).</li>

<li>I have a <code>User</code> object that <em>has many</em> <code>Image</code>s</li>
<li><code>Image</code> <em>belongs to</em> <code>User</code>... (inverse relation)</li>
</ul>
<p>My problem is that I want to eager load both the <code>images()</code> on the <code>User</code> model and the <code>user()</code> on the <code>Image</code> model. To do so, I just setup a <code>$with</code> property as explained in the docs.</p>
<p>My <code>User</code> model:</p>
<pre class="lang-php prettyprint-override"><code>class User extends EloquentModel {
protected $with = ['images'];
public function images()
{
return $this->hasMany(Image::class);
}
}
</code></pre>
<p>My <code>Image</code> model:</p>
<pre class="lang-php prettyprint-override"><code>class Image extends EloquentModel {
protected $with = ['user'];
public function user()
{
return $this->belongsTo(User::class);
}
}
</code></pre>
<p>But when performing:</p>
<pre class="lang-php prettyprint-override"><code>$user = User::find(203);
</code></pre>
<p>This results in an infinite loop (php segmentation fault). There must be some kind of circular reference that I am not able to locate:</p>
<pre><code>[1] 85728 segmentation fault
</code></pre>
<p><strong>EDIT 2016/02</strong></p>
<p>This is the simplest "Workaround" I found:</p>
<pre class="lang-php prettyprint-override"><code>// User.php
public function setRelation($relation, $value)
{
if ($relation === 'images') {
foreach ($value as $image) {
$image->setUser($this);
}
}
return parent::setRelation($relation, $value);
}

Kendoui- set color in chart dynamically | <p>When we work with KendoUI, we need to specify the backcolor of the chart. like this:</p>
<pre><code>{
category: "Latin America",
value: 16.3,
color: "#068c35"
}
</code></pre>
<p>See the full code below or example <a href="http://dojo.telerik.com/OtUmi" rel="nofollow">here</a>. I want to know, instead of specifying the backcolor for each component, is it possible to set the base color and then kendoui will use variation of the base color and set the backcolor for remaining component. </p>

Go cgo ldap_init could not determine kind of name for C.ldap_init | <p>I was trying to learn and understand cgo.
I am writing a program in Go where I connect to AD and parse the output. I tested the code in C, which is working fine as expected. The relevant part in <code>C</code> is</p>
<pre><code>char *ldap_host = "x.x.x.x";
int ldap_port = 389;
ldap = ldap_init(ldap_host, ldap_port))
</code></pre>
<p>Now I am trying to get the same working in go as</p>
<pre><code>//#cgo CFLAGS: -lldap
//#include <ldap.h>
import "C"
func main() {
var hostname *string
hostname = &os.Args[1]
ldap_port := 389

Swift: Are global functions bad practice? | <p>I've read that global variables are bad. But, what about global functions? Say I add to my iPhone app project a file called <code>Globals.swift</code> containing <code>func foo() { print("foo") }</code>. Isn't that bad because it could conflict with other global functions of the same name & signature? By the same argument, isn't it bad to use extensions to add new methods to existing types?</p> | 1 |

How to checkin files to TFS in new build task | <p>We try to migrate our old XAML build to new build system with task on on-premise TFS2015 Update1. In XAML build we have step where we check-out some files do some modification and do check-in. I found powershell <a href="https://github.com/Microsoft/vso-agent-tasks/blob/5809b4e83531ce21fdde486c77283810c1498277/Tasks/PublishSymbols/LegacyIndexHelpers.ps1" rel="nofollow noreferrer">helper</a> where is connection to TFS. Than I can check-out files, get list of pending check-out, but cannot do check-in. When I call</p>
<pre><code>$tfsProvider.Workspace.CheckIn($pendingChanges, "some text")
</code></pre>
<p>I get error</p>
<pre><code>Exception calling "CheckIn" with "2" argument(s): "Could not load file or assembly 'Microsoft.TeamFoundation.WorkItemTracking.Client, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies

<p>I think problem is that assembly Microsoft.TeamFoundation.VersionControl.Client.dll depends on assembly Microsoft.TeamFoundation.WorkItemTracking.Client. But this assembly is not in Agent worker folder. Is only way to get this assembly to copy to agent folder or install VS2015 on machine with agent and load assembly from VS folder?</p>

MongoDB index: object keys vs array of strings | <p>I'm new to the MongoDB and have been researching schema designs and indexing. I know you can index a property regardless of its value (ID, array, subdocument, etc...) but what I don't know is if there is a performance benefit to either indexing an array of strings or a nested object's keys.</p>
<p>Here's an example of both scenarios that I'm contemplating (in Mongoose):</p>
<pre><code>// schema
mongoose.Schema({
visibility: {
usa: Boolean,
europe: Boolean,
other: Boolean
}
});
// query
Model.find({"visibility.usa": true});
</code></pre>
<p>OR</p>
<pre><code>// schema
mongoose.Schema({
visibility: [String] // strings could be "usa", "europe", and/or "other"
});
// query
Model.find({visibility: "usa"});
</code></pre>
<p>Documents could have one, two, or all three visibility options.</p>
<p>Furthermore, if I went with the Boolean object design, could I simple index the visibility field or would I need to put an index on usa, europe, and other?</p> | 1 |

how to copy one index documents to other index in elasticsearch? | <p>I created a new index with mappings. 500 000 documents are stored in it.</p>
<p>I want to change the mapping of the index, but it is not possible in elastic search.so I created another index with new new mappings and now I am trying to copy the documents from old index to new index.</p>
<p>I am using scan and scroll type to retrieve the documents from old index and copying to new index.for copying its taking more time and the system is slowing down.</p>
<p>Below is the code that I am using.</p>
<pre><code>$client= app('elastic_search');
$params = [
"search_type" => "scan", // use search_type=scan
"scroll" => "30s", // how long between scroll requests. should be small!
"size" => 500000, // how many results *per shard* you want back
"index" => "admin_logs422",
"body" => [
"query" => [
"match_all" => []
]
]
];
$docs = $client->search($params); // Execute the search
$scroll_id = $docs['_scroll_id'];
while (\true) {
// Execute a Scroll request
$response = $client->scroll([
"scroll_id" => $scroll_id, //...using our previously obtained _scroll_id
"scroll" => "500s" // and the same timeout window
]
);
if (count($response['hits']['hits']) > 0) {
foreach($response['hits']['hits'] as $s)
{
$params =
[
'index' => 'admin_logs421',

'timeout' => 10,
'connect_timeout' => 10

'body' => $s['_source']
];
$response = app('elastic_search')->create($params);

Bootstrap 3 data-target attribute on tab not working | <p>I am using Bootstrap tabs in my website. When page loads tab will be filled with data at run-time using dynamic content. I am using <code>data-target</code> attribute on anchor tag for that, but it does not seems to work at all.</p>
<p>Here is what I tried so far:</p>
<p><strong>HTML</strong></p>
<pre><code><div class="container">
<div class="row">
<ul class="nav nav-tabs" role="tablist">
<li role="presentation" class="active">
<a href="showTab1.do" data-target="#test_1" aria-controls="test_1" role="tab" data-toggle="tab">Tab 1</a>
</li>
<li role="presentation">
<a href="showTab2.do" data-target="#test_2" aria-controls="test_2" role="tab" data-toggle="tab">Tab 2</a>
</li>
<li role="presentation">
<a href="showTab3.do" data-target="#test_3" aria-controls="test_3" role="tab" data-toggle="tab">Tab 3</a>
</li>
</ul>
<div class="tab-content">
<div role="tabpanel" class="tab-pane active" id="test_1"></div>
<div role="tabpanel" class="tab-pane active" id="test_2"></div>
<div role="tabpanel" class="tab-pane active" id="test_3"></div>
</div>
</div>
</div>
</code></pre>
<p>Here I am trying to load content of remote file <code>showTab1.do</code> inside div with <code>id="test_1"</code> when using <code>data-target="#test_1"</code> on anchor tag. But it is not working. What I know is if I am using <strong>data-target</strong> we don't need to write any jQuery/JavaScript to load data in tab as data-target will do that for us(correct me if I am wrong).
My Bootstrap version is v3.3.6.</p>
<p>Please correct me where I am wrong.
Thanks </p> | 1 |
GLSL cube signed distance field implementation explanation? | <p>I've been looking at and trying to understand the following bit of code</p>
<pre><code>float sdBox( vec3 p, vec3 b )
{
vec3 d = abs(p) - b;
return min(max(d.x,max(d.y,d.z)),0.0) +
length(max(d,0.0));
}
</code></pre>
<p>I understand that <code>length(d)</code> handles the SDF case where the point is off to the 'corner' (ie. all components of <code>d</code> are positive) and that <code>max(d.x, d.y, d.z)</code> gives us the proper distance in all other cases. What I don't understand is how these two are combined here without the use of an if statement to check the signs of <code>d</code>'s components.</p>
<p>When all of the <code>d</code> components are positive, the return expression can be reduced to <code>length(d)</code> because of the way <code>min/max</code> will evaluate - and when all of the <code>d</code> components are negative, we get <code>max(d.x, d.y, d.z)</code>. But how am I supposed to understand the in-between cases? The ones where the components of <code>d</code> have mixed signs?</p>
<p>I've been trying to graph it out to no avail. I would really appreciate it if someone could explain this to me in geometrical/mathematical terms. Thanks.</p> | 1 |
Using Flexbox order with Bootstrap rows | <p>I am trying to adjust the stacking order of columns within two bootstrap rows. I have two rows, each with two columns. In my JSBin example below, I am trying to stack the order on a phone to thing a, thing b, thing d and thing c. </p>

AWS CLI create Lambda function cannot unzip uploaded file | <p>I'm trying to create an AWS Lambda function using the AWS CLI. So I generated the JSON input skeleton for use with the <code>aws lambda create-function</code> function by passing in the <code>--generate-cli-skeleton</code> parameter and then substituting the values accordingly.</p>
<p>The problem is that when I execute the command to create the function it gives me this error:</p>
<p><code>A client error (InvalidParameterValueException) occurred when calling the CreateFunction operation: Could not unzip uploaded file. Please check your file, then try to upload again.</code></p>
<p>This is how I run the command:</p>
<p><code>aws lambda create-function --cli-input-json file://C:\Projects\Automated_Deployment\lambda_function_deploy.json</code></p>
<p>The contents of the <em>.json</em> file are:</p>
<pre><code>{
"FunctionName": "MyFunction",
"Runtime": "nodejs",
"Role": "arn:aws:iam::------------:role/lambda_dynamo",
"Handler": "index.handler",
"Code": {
"ZipFile": "fileb://C:/Projects/src/zip/MyFunction.zip"
},
"Description": "description goes here",
"Timeout": 10,
"MemorySize": 128,
"Publish": true
}
</code></pre>
<p>Surprisingly if I try to create the function without using the JSON file and providing all the parameters in the command-line then it works. So for instance, this works without any issues at all:</p>
<pre><code>aws lambda create-function --function-name MyFunction --runtime nodejs --role arn:aws:iam::------------:role/lambda_dynamo --handler index.handler --zip-file fileb://C:/Projects/src/zip/MyFunction.zip
</code></pre>
<p>This is the same .zip file. Any hints as to what am I doing wrong here? I have tried replacing <code>"ZipFile": "fileb://C:/Projects/src/zip/MyFunction.zip"</code> with:</p>
<p><code>"ZipFile": "file://C:/Projects/src/zip/MyFunction.zip"</code> and <code>"ZipFile": "C:/Projects/src/zip/MyFunction.zip"</code> but the issue remains.</p>
<p><strong>EDIT:</strong>
I found out the --debug option which we can pass to the CLI command. The problem is that the tool is not reading the ZipFile properly when we provide the input from JSON. So for instance if I run the command providing all the parameters in the command itself, I can see the zip file properly base64 encoded i.e.:</p>
<pre><code>2016-02-08 10:43:59,831 - MainThread - botocore.endpoint - DEBUG - Making request for <botocore.model.OperationModel object at 0x0000000004149F28> (verify_ssl=True) with params: {'body': '{"Code": {"ZipFile": "UEsDBBQAAAAIAFiGPUiLOeW/nwcAANsdAAAIAAAAaW5kZXguanO1Gdtu2zb0PUD+gdVDI2OOmrZrBzgICi9OC29FYsRpX4pCUCQ65iJLqk
....
redacted
</code></pre>
<p>But when I provide the parameters from the JSON file i.e. --cli-input-json then the command base64 encodes the value of the ZipFile key in the JSON (which is the URI to that file i.e. fileb://C:/Projects/src/zip/MyFunction.zip)</p>
<p>Now I'm not sure what value we need to provide to the ZipFile key, or is it a bug in the tool/command?</p>
<p><strong>EDIT2:</strong> If I provide the base64 encoded string of my zip file, the command will base64 encode that string again which will gave the same error (i.e. cannot unzip.) So my question is what does the field ZipFile require? A URL with file:// protocol or fileb:// ? Zip file's contents base-64 encoded?</p> | 1 |
