37,210,198 | How to route CodeIgniter with Angular.js? | <p>I'm trying to use Angular.js and CodeIgniter together. </p>

$routeProvider.when('/test', {
templateUrl: 'partials/test.html'

<p>The error occurs in the last while loop when executing fgets();
I have looked if I had any variable or syntax wrong, but everything looks fine.
This is a part of a two pass assemble. The error varies between the fgets in the last while loop. At first I thought that it was the memset function, but the error still happened when I mark them as comments</p>

I run the program, and it says:
***Launch failed. Binary not found.***
This is the code for the program:
`#include <stdio.h>
#include <stdlib.h>
int main(void) {
puts("Hello World!");
return EXIT_SUCCESS;
}`
There are two errors, too:
1. Function "puts" couldn't be resolved.
2. Symbol "EXIT_SUCCESS" couldn't be resolved.
Thanks in advance!

37,217,271 | Static Polymorphism with boost variant single visitor vs multi visitor vs dynamic polymorphism | <p>I am comparing the performance of the following methods of C++ Polymorphism:</p>
<p>Method [1]. static polymorphism using boost variants with a separate visitor for each method
Method [2]. static polymorphism using boost variants with a single visitor that calls different method using method overloading
Method [3]. Plain old dynamic polymorphism</p>
<p>Platform:
- Intel x86 64 bit Red Hat modern multi-core processor, 32 GB RAM
- gcc (GCC) 4.8.1 with -O2 optimization
- Boost 1.6.0</p>
<p>Some findings:</p>
<ul>
<li>Method [1] seems to have significantly outperform Methods [2] and [3]</li>
<li>Method [3] outperforms Method [2] most of the time</li>
</ul>
<p>My question is, why does Method [2] where I am using a visitor but using method overloading to call the correct method give worse performance than virtual methods. I would expect static polymorphism to fare better than dynamic polymorphism. I understand there is some cost of the extra parameter that is being passed in method [2] to figure which visit() method of the class to call and possibly some more branching due to method overloading? But shouldn"t this still outperform virtual methods?</p>

37,220,488 | Importing data from multiple text files into Excel VBA | <p>I might have a question about VBA and Excel Macros. The thing that I need to do is to import data (actually integer values) from multiple text files that have random generated names (for example 12345678.txt, 8654321.txt, etc.) but which are stored in the same folder (let's call it Data folder) to excel into a column. </p>
<p>The problem that I face is that I have the same name for the measured values (called MVA) that are repeating over and over in the text files. I don't need all the data from the text files, only some specific rows of these MVA (for the example below let's say that I need only the MVA number for the "LED 01 Intensity" which is 6250 to be stored in a new cell in Excel. And I need to get that value that comes after "LED 01 Intensity" in the MVA row from 10 multiple text files (with random names that I don't know) to be stored each one in separate cells in Excel (from A1 to A10).</p>
<p>Example_____________________________________________________________________</p>
<p>Name: 153588.txt</p>
<p>Date: 14.05.2016</p>
<p>Name of product: Electronic Device 01</p>
<p>CHECK TEST</p>
<p>Resistance 101</p>
<p>MVA: 2 Ohm</p>
<p>MAX: 5 Ohm</p>
<p>MIN: 0 Ohm</p>
<p>PASS</p>
<p>LED 01 Intensity</p>
<p>MVA: 6250</p>
<p>MAX: 10000</p>
<p>MIN: 5000</p>
<p>PASS</p>
<hr>
<p>I need a lot of these MVA values to be stored in Excel for analysis and I need to get an idea if this problem can be solved with VBA. If you can offer me some help to create a macro for this I would be thankful (I have basic knowledge of programming but I'm a beginner in VBA).</p>

<p>The most straightforward way, of course, is</p>

<p>I tried using <code>reduce</code>:</p>
<pre><code>let y = x.reduce([Int]()) { (array, ints) -> [Int] in
array.appendContentsOf(ints)

}
</code></pre>
<p>But the compiler complains that <code>array</code> is immutable, so I can't call the mutating method <code>appendContentsOf</code>. </p>

newArr.appendContentsOf(ints)

37,221,456 | Why can I assign a value of different type to a variable? | <p>In the book "Go in Action", the author wrote "Values of two different types can’t be assigned to each other, even if they’re compatible".</p>
<p>For example, we can't assign <code>Duration</code> to <code>int64</code> or <code>int64</code> to <code>Duration</code>.</p>
<p>But this is not always true, the following assignment would work like the <code>X</code> value is converted back to <code>[]int</code> automatically:</p>
<pre><code>type X []int
var v []int = X([]int{1, 2, 3})
</code></pre>
<p>What's the difference between these two situations?</p>

<p>I am aware of how to test if a file exists with <code>fileExistsAtPath()</code>, which returns a bool "true" if the file exists and "false" if it doesn't (assuming <code>path</code> is a string containing the path to the file):</p>
<pre><code>if NSFileManager.fileExistsAtPath(path) {
print("File exists")
} else {
print("File does not exist")
}
</code></pre>
<p>However, I would like to check if the path specified in <code>path</code> is a directory, similar to the following <code>bash</code> code:</p>
<pre><code>if [ -d "$path" ]; then
echo "$path is a directory"
elif [ -f "$path" ]; then
# this is effectively the same as fileExistsAtPath()
echo "$path is a file"
fi

<p>But I also want to support custom elements like:</p>

{name: 'Age', type: 'custom', customid: 'Ctl1'},
{name: 'Whatever', type: 'custom', customid: 'Ctl2'}

<a href="http://elm-lang.org/examples/random" rel="noreferrer">http://elm-lang.org/examples/random</a></p>
<p>There is a follow up challenge to add a second die to the example, so that a single click of the button rolls a new value for each die. My idea is to change the model to hold two separate values, one for each die, ala</p>
<pre><code>type alias Model =
{ dieFace1 : Int
, dieFace2 : Int
}
</code></pre>
<p>This works fine until I get to the update block. I am not sure how to update the Random number generator to create two values. The function is a bit confusing to me.</p>
<pre><code>type Msg
= Roll
| NewFace Int Int
update : Msg -> Model -> (Model, Cmd Msg)
update msg model =
case msg of
Roll ->
**(model, Random.generate NewFace (Random.int 1 6))** <-- not sure what to do here
NewFace newFace1 newFace2 ->
(Model newFace1 newFace2, Cmd.none)
</code></pre>
<p>The documentation for the Random.generate function is a bit light - </p>
<blockquote>
<p>generate : (a -> msg) -> Generator a -> Cmd msg</p>
<p>Create a command that will generate random values.</p>
</blockquote>

<p>I'm learning JavaScript and starting into underscore.js and came along <a href="http://underscorejs.org/#oop" rel="noreferrer">this</a> small section in the docs.
The docs say that underscore.js can be used in a Object-Oriented or Functional style and that both of these result in the same thing.</p>
<pre><code>_.map([1, 2, 3], function(n){ return n * 2; });
_([1, 2, 3]).map(function(n){ return n * 2; });
</code></pre>
<p>I don't understand which one is functional and which one is OOP, and I don't understand why, even after some research into these programming paradigms.</p>

37,232,061 | Lazarus - No Form Window, Dialogue Grey'd Out | <p>I've got a wee bit of experience with Pascal, as I've used it to create mods via TES5Edit for Skyrim, and I've hit a wee snag with modding Dark Souls, and I figured flexin' me Pascalerrific muscles would be a good exercise.</p>
<p>But, uh, it's all buggered right from the get go. Lazarus supposedly has this "Form Window" feature, where ya can just click one of the icons and then click on the IDE, and bam. Automated GUI creation.</p>
<p>I ain't got that. The window isn't up, and the option to open it is grey'd out. 'Eres an image to demonstrate:</p>

37,232,827 | AWS lambda function stops working after timed out error | <p>I have a simple lambda function that asynchronously makes an API calls and then returns data. 99% of the time this works great. When ever the API takes longer then the lambda configured timeout, it gives an error as expected. Now the issue is that when I make any subsequent calls to the lambda function it permanently gives me the timeout error.</p>
<pre><code> "errorMessage": "2016-05-14T22:52:07.247Z {session} Task timed out after 3.00 seconds"
</code></pre>
<p>In order to test that this was the case I set the lambda timeout to 3 seconds and have a way to trigger these two functions within the lambda. </p>
<p><strong>Javascript</strong></p>
<pre><code>function now() {
return response.tell('success');
}
function wait() {
setTimeout(function() { return response.tell('success'); }, 4000);
}
</code></pre>
<p>When I call the <code>now</code> function there are no problems. When I call the <code>wait</code> function I get the timeout error and then any subsequent calls to <code>now</code> give me the same error.</p>
<p>Is this an expected behavior? I would think that any subsequent calls to the lambda function should work. I understand I can always increase the configuration timeout, but would rather not. </p>

37,232,884 | In Python: How to remove an object from a list if it is only referenced in that list? | <p>I want to keep track of objects of a certain type that are currently in use. For example: Keep track of all instances of a class or all classes that have been created by a metaclass.</p>
<p>It is easy to keep track of instances like this:</p>
<pre><code>class A():
instances = []
def __init__(self):
self.instances.append(self)
</code></pre>
<p>But if an instance is not referenced anywhere outside of that list it will not be needed anymore and I do not want to process that instance in a potentially time consuming loop.</p>
<p>I tried to remove objects that are only referenced in the list using sys.getrefcount.</p>
<pre><code>for i in A.instances:
if sys.getrefcount(i) <=3: # in the list, in the loop and in getrefcount
# collect and remove after the loop
</code></pre>
<p>The problem I have is that the reference count is very obscure.
Opening a new shell and creating a dummy class with no content returns 5 for</p>
<pre><code>sys.getrefcount(DummyClass)
</code></pre>
<p>Another idea is to copy the objects then deleting the list and checking which objects have been scheduled for garbage collecting and in the last step removing those objects. Something like:</p>
<pre><code>Copy = copy(A.instances)
del A.instances
A.instances = [i for i in Copy if not copy_of_i_is_in_GC(i)]
</code></pre>
<p>The objects don't have to be removed immediately when the reference count goes to 0. I just don't want to waste too much ressources on objects that are not used anymore.</p>

Algorithm | <p>Does anyone know how to make an algorithm that transforms a binary search tree into an AVL tree, and yes transform it and not make another tree (so it will only be done using rotations) and not with the DSW technique... and in C. The tricky part here is that there is lots of cases since a binary search tree can be unbalanced in various ways and there being 4 types of rotations.</p>

37,239,881 | Create implementation of Java class dynamically based on provided dependencies at runtime | <p>I'm trying to determine the best way to create a new instance of a class based on which classes are available on the classpath at runtime.</p>
<p>For example, I have a library that requires a JSON response to be parsed in multiple classes. The library has the following interface:</p>
<p><code>JsonParser.java</code>:</p>
<pre><code>public interface JsonParser {
<T> T fromJson(String json, Class<T> type);
<T> String toJson(T object);
}
</code></pre>
<p>This class has multiple implementations, i.e. <code>GsonJsonParser</code>, <code>JacksonJsonParser</code>, <code>Jackson2JsonParser</code>, and currently, the user of the library is required to "pick" their implementation to be used based on which library they've included in their project. For example:</p>
<pre><code>JsonParser parser = new GsonJsonParser();
SomeService service = new SomeService(parser);
</code></pre>
<p>What I'd like to do, is dynamically pick up which library is on the classpath, and create the proper instance, so that the user of the library doesn't have to think about it (or even have to know the internal implementation of another class parses JSON).</p>
<p>I'm considering something similar to the following:</p>
<pre><code>try {
Class.forName("com.google.gson.Gson");
return new GsonJsonParser();
} catch (ClassNotFoundException e) {
// Gson isn't on classpath, try next implementation
}
try {
Class.forName("com.fasterxml.jackson.databind.ObjectMapper");
return new Jackson2JsonParser();
} catch (ClassNotFoundException e) {
// Jackson 2 was not found, try next implementation
}
// repeated for all implementations
throw new IllegalStateException("You must include either Gson or Jackson on your classpath to utilize this library");
</code></pre>
<p>Would this be an appropriate solution? It seems kind of like a hack, as well as uses exceptions to control the flow.</p>
<p>Is there a better way to do this?</p>

This code here works:

.attr("x", 70)
.attr("y", 20)
.style("font-size", "16px")
.style("text-decoration", "underline")

but i have problems in this one as i am unable to

When i assign it width or height it just does,nt gets applied.
Also changing the display to block is not working...

37,240,621 | Django-Rest-Framework. Updating nested object | <p>I'm having a problem of updating a nested object.</p>
<p>So I have a model which structure is similar to this one:</p>
<pre><code>class Invoice(models.Model):
nr = models.CharField(max_length=100)
title = models.CharField(max_length=100)
class InvoiceItem(models.Model):
name = models.CharField(max_length=100)
price = models.FloatField()
invoice = models.ForeignKey(Invoice, related_name='items')
</code></pre>
<p>I need to create child objects from parent, and what I mean by that, is to create <code>InvoiceItems</code> directly when creating an <code>Invoice</code> object.
For this purpose, I've wrote the following serializers:</p>
<pre><code>class InvoiceItemSerializer(serializers.ModelSerializer):
invoice = serializers.PrimaryKeyRelatedField(queryset=Invoice.objects.all(), required=False)
class Meta:
model = InvoiceItem
class InvoiceSerializer(serializers.ModelSerializer):
items = InvoiceItemSerializer(many=True)
class Meta:
model = Invoice
def create(self, validated_data):
items = validated_data.pop('items', None)
invoice = Invoice(**validated_data)
invoice.save()
for item in items:
InvoiceItem.objects.create(invoice=invoice, **item)
return invoice
</code></pre>
<p>Up till now, the create/read/delete methods work perfectly, except the <code>update</code>.
I think the below logic should be correct, but it misses something.</p>
<pre><code>def update(self, instance, validated_data):
instance.nr = validated_data.get('nr', instance.nr)
instance.title = validated_data.get('title', instance.title)
instance.save()
# up till here everything is updating, however the problem appears here.
# I don't know how to get the right InvoiceItem object, because in the validated
# data I get the items queryset, but without an id.
items = validated_data.get('items')
for item in items:
inv_item = InvoiceItem.objects.get(id=?????, invoice=instance)
inv_item.name = item.get('name', inv_item.name)
inv_item.price = item.get('price', inv_item.price)
inv_item.save()
return instance
</code></pre>
<p>Any help would be really appreciated.</p>
