Make request POST angular 1.x using 'Content-Type': 'application/json' : Previously I used the following type of headers in my function to make the request from the application:
###Html
<label class="item item-input">
<i class="icon ion-person placeholder-icon"></i>
<input type="text" placeholder="Usuario" ng-model="usuariotxt">
</label>
<label class="item item-input">
<i class="icon ion-key placeholder-icon"></i>
<input type="password" placeholder="Contraseña" ng-model="passwordtxt">
</label>
###Data Login
datos = {
Usuario: $scope.usuariotxt,
Password: $scope.passwordtxt
};
`'Content-Type': 'application/x-www-form-urlencoded'`
###function
function Autenticacion(datos) {
var url = 'http://API_URL';
return $http.post(url, $httpParamSerializer(datos), {
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
});
};
Now the content-type must be different from how you submitted the request in advance
`'Content-Type': 'application/json'`
function Autenticacion(datos) {
//var url = 'API_URL';
return $http.post(url, $httpParamSerializer(datos), {
headers: {
'Content-Type': 'application/json'
}
});
};
But using the ARC tool, the request works perfectly

AWS S3 integration yields undefined method `match' : <p>I'm working on a simple project using Paperclip to upload images. Everything has been working just fine until I attempted to integrate S3 with Paperclip. Upon 'uploading' a user's image I get a <code>NoMethodError (undefined method 'match' for nil:NilClass):</code> error. This only happens when I have my S3 configuration running - if I comment it out the file uploads perfectly. </p>
<p>My configuration:</p>
<pre><code>development.rb:
....
....
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
:bucket => ENV['AWS_BUCKET_ID'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
}
</code></pre>
<p>My Model:</p>
<pre><code> class User < ActiveRecord::Base
has_attached_file :image_file, default_url: "/myapp/images/:style/missing.png"
validates_attachment_file_name :image_file, matches: [/png\Z/, /jpeg\Z/, /tiff\Z/, /bmp\Z/, /jpg\Z/]
</code></pre>
<p>entire error output from console:</p>
<pre><code>NoMethodError (undefined method `match' for nil:NilClass):
app/controllers/images_controller.rb:33:in `block in create'
app/controllers/images_controller.rb:32:in `create'
</code></pre>
<p>Things I tried:</p>
<ul>
<li><p>I added the AWS keys and bucket name directly into the code instead
of as an environmental variable.</p></li>
<li><p>As mentioned above, I commented out the AWS configuration in my environment file and it seemed to work perfectly.</p></li>
</ul>
<p>It's probably worth mentioning that I installed the <code>fog</code> gem earlier to start configuring for Google Cloud Storage, but decided to stick with S3 instead. I used <code>gem uninstall fog</code> to remove the gem but it appears some dependencies stayed behind. </p>

How does spring dependency injection work? : <p>I want to know when are the dependencies injected in a spring bean.
I have the following code :</p>
<pre><code>import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.stereotype.Component;
@Component
public class TestClass {
@Autowired
Environment env;
// throws Null Pointer Here.
String prop = env.getProperty("some.property");
public void test() {
// works here
String prop = env.getProperty("some.property");
}
}
</code></pre>
<p>Why does spring throws NPE when I try to get Environment variable.
What happens when the class constructor is called? Does spring only looks for bean availability in the context at construction time and not inject it then and there? Please explain the full flow of bean creation. Are the dependencies only injected after the object is constructed and added to the context? Does spring look for dependencies only after an instance of the class is created or does it look for them when the constructor is called?</p>

Regular expressions doubts : <p>I have a few doubts that I have not managed to clear up by research and am hoping for some help.</p>
<p>1) What does the <code>m</code> do, and what do the <code>/ /</code> before the m and at the end do?
$var =~ m/[^0-9]+/</p>
<p>2) <code>/[^0-9]+/</code> Which of the following lines does this regex match?</p>
<pre><code> A) `123`
B) `4`
C) `I see 5 dogs`
D) `I see five dogs`
</code></pre>
<p>My answer to 2): It matches <code>C</code> and <code>D</code>, and not <code>A</code> and <code>B</code> because there is no character or wold that does not contain <code>0-9</code>.</p>

Display the same data and summation in mysql : I want to ask and hopefully the readers can help.
I have a case showing data details based on order number.
the following data.
+ order number | item | total kg<br>
1. 99684 | CF Rice Pandan Wangi 10 kg | 50.0 kg<br>
2. 99684 | CF Rice Rojolele 10 kg | 100.0 kg<br>
3. JK14020 | CF Rice Pandan Wangi 10 kg | 20.0 kg
I would like if if there is the same name it only appears 1x and its total kg increases also according to the total details per each of them, is there any solution for this?
I just use looping without any condition, do not know how. | 0debug |

Keras - using activation function with a parameter : <p>How is it possible to use leaky ReLUs in the newest version of keras?
Function relu() accepts an optional parameter 'alpha', that is responsible for the negative slope, but I cannot figure out how to pass ths paramtere when constructing a layer. </p>
<p>This line is how I tried to do it,</p>
<pre><code>model.add(Activation(relu(alpha=0.1))
</code></pre>
<p>but then I get the error</p>
<pre><code>TypeError: relu() missing 1 required positional argument: 'x'
</code></pre>
<p>How can I use a leaky ReLU, or any other activation function with some parameter?</p>

Is it safe to link gcc 6, gcc 7, and gcc 8 objects? : <p><a href="https://stackoverflow.com/q/46746878/2069064">Is it safe to link C++17, C++14, and C++11 objects</a> asks about linking objects compiled with different language standards, and Jonathan Wakely's excellent answer on that question explains the ABI stability promises that gcc/libstdc++ make to enusure that this works.</p>
<p>There's one more thing that can change between gcc versions though - the language ABI via <a href="https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Dialect-Options.html" rel="noreferrer"><code>-fabi-version</code></a>. Let's say, for simplicity, I have three object files:</p>
<ul>
<li><code>foo.o</code>, compiled with gcc 6.5 c++14</li>
<li><code>bar.o</code>, compiled with gcc 7.4 c++14</li>
<li><code>quux.o</code>, compiled with gcc 8.3 c++17</li>
</ul>
<p>All with the respective default language ABIs (i.e. 10, 11, and 13). Linking these objects together is safe from the library perspective per the linked answer. But are there things that could go wrong from a language ABI perspective? Is there anything I should be watching out for? Most of the language ABI changes seem like they wouldn't cause issues, but the calling convention change for empty class types in 12 might?</p>

In C++ how can I extract members from an array and return an array of the member's type? : <pre><code>namespace detail
{
template <typename T, typename U>
Array<U> extract_(const Array<T>& array, std::function<U(const T&)> member)
{
Array<U> extracted;
for (auto& item : array)
extracted += member(item);
return extracted;
}
}
#define extract(container, member) detail::extract_(container, \
std::function< typeof(typeof(container)::Type::element_type::member) (const typeof(container)::Type&)>( \
[&](const typeof(container)::Type& item){ return item->member; }))
</code></pre>
<p>So that's the algorithm I want to use to extract members from arrays. <code>Array<T></code> is my homegrown array type, it handles bidness.</p>
<p>If you're allergic to macros, sorry, but it makes user code very clean.</p>
<p>What I want to do is if I have <code>Array<Size> sizeArray</code> with member <code>double Array<Size>::Length</code>, to be able to say <code>auto lengths = extract(sizeArray, Length);</code> and have <code>lengths</code> be of type <code>Array<double></code>.</p>
<p>I already do something similar with</p>
<pre><code>namespace detail
{
template <typename T>
Array<T> filter_(const Array<T>& array, std::function<bool(const T&)> condition)
{
Array<T> filtered;
for (auto& item : array)
if (condition(item)) filtered += item;
return filtered;
}
}
// this macro creates a capturing lambda, the item to check is called 'item'
#define filter(container, condition) detail::filter_(container, \
std::function<bool(const typeof(container)::Type&)>( \
[&](const typeof(container)::Type& item){ return condition; }))
</code></pre>
<p>I can do <code>auto turnedOff = filter(objects, !item->IsTurnedOn);</code> and it works really well, but it's returning the same type, so it's an easier task to solve.</p>

Does chnaging v4l2 default settings improves usb camera performance? : I'm have USB ELP camera. I'm using v4l2 driver to capture images from that USB camera. I've found that we can change v4l2 default parameters like brightness, contrast, gamma, exposure, resolution. Can we able to increase the speed of camera access time so that it can captures images at less time by changing these parameters to optimum values ?
Thanks for advice.

How to add an image in an SQL database? : I'm currently working in Microsoft Visual studio and I am doing a project for school where I have to make an app that lets you book seats at a cinema and see the description of the movie you have selected as well as leave/read a review.
In my app I have decided that I want to include pictures (basically a poster for each of the movies); I have made my "Movies" table and have "idf" as my primary key. I have added a "poster" column in my table definition and I have set its type to image; my question is, how do I assign a certain image to a movie, so as to have access to it and to be able to display it later using a query of some sort?

Eslint errorring importing jsx without extension : <p>I am trying, in es6, to import jsx files without requiring the .jsx extension:</p>

Can link prefetch be used to cache a JSON API response for a later XHR request? : <p>Given a JSON API endpoint <code>/api/config</code>, we're trying to use <code><link rel="prefetch" href="/api/config"></code> in the head of an HTML document. Chrome downloads the data as expected when it hits the link tag in the HTML, but requests it again via XHR from our script about a second later.</p>
<p>The server is configured to allow caching, and is responding with <code>Cache-Control: "max-age=3600, must-revalidate"</code> in the header. When Chrome requests the data again, the server responds correctly with a 304 Not Modified status.</p>
<p>The use case is this: the config endpoint will always be requested from the Javascript in our single page application using XHR (an AngularJS resolve, in case it's relevant). However, our scripts are very large and take a long time to parse, so the JSON config will not be requested until the parsing is finished. Prefetching would allow us to use some of that parsing time to fetch and cache responses from API endpoints that would otherwise have to wait for the scripts to load.</p>

vector<Agent> population;
for (vector<int>::iterator i = population.begin(); i != population.end(); ++i) {
population.push_back(new Agent(generateDna(targetString.size())));
}
i get the following errors
1.
no suitable user-defined conversion from "__gnu_cxx::__normal_iterator<Agent *, std::vector<Agent, std::allocator<Agent>>>" to "__gnu_cxx::__normal_iterator<int *, std::vector<int, std::allocator<int>>>" exists
2.
no operator "!=" matches these operands -- operand types are: __gnu_cxx::__normal_iterator<int *, std::vector<int, std::allocator<int>>> != __gnu_cxx::__normal_iterator<Agent *, std::vector<Agent, std::allocator<Agent>>>
3.
no instance of overloaded function "std::vector<_Tp, _Alloc>::push_back [with _Tp=Agent, _Alloc=std::allocator<Agent>]" matches the argument list -- argument types are: (Agent *) -- object type is: std::vector<Agent, std::allocator<Agent>>

How can I print data that i filtered out of my mysql table : I am currently developing a school project and once again require some advice from fellow coders. I basically have a mysql table from which i filter out data (according to conditions). I used to print this filtered data to the console, however I now want to go further and want to print the results.
Is there a simple way to maybe write the data to another table and print it?
If not is there perhaps a way to just export the data (maybe in the form of a txt.file)?
My problem is basically that i am still a beginner who doesn't know most of the Java terms and functions. It would therefore be very helpful if someone could perhaps recommend a simple way to fulfil the above requirements.
Thank you for your help :)!!

Split an array of strings into other array of stings : I`m making a project, which gets an array of strings from a .txt file, which contains the two names of a person. The problem is that when i try to split the elements from the string "line" and try to give other two strings those values, something happens.
The text file contains:
"Noah Mason
Emma Williams
Richard Daniel
and so on..."
I want to split the lines into two separate arrays of stings "firstName" and "secondName". And i want something like this:
firstName[0]="Noah";
firstName[1]="Emma";
firstName[2]="Richard";
secondName[0]="Mason";
secondName[0]="Williams";
secondName[0]="Daniel";
Thank you in advance! | 0debug |
Why do I get no error when running one codes on multiple terminals? : I'm parsing text files with Python code on Linux.
I never majored in computer, and I don't know what material to look for and which keyword to search for.
Using vim on multiple terminals targeting a file on Linux gives an error. (Maybe because of temporary files?)
And When I open a file in Python, the file once read through must reset the pointer.
BUT, I am now processing multiple files,same time, using a single piece of code (ex,"a.py").
So suddenly I was curious, why do I get no error when running one codes on multiple terminals?
Isn't the code going to be related to pointers?
Or do I get a temporary file to which copied the code when using it? | 0debug |

At my opinion fisrt example should return <code>false</code> too, but it isn't. What am I doing wrong?</p>
