How do you use @Input with components created with a ComponentFactoryResolver? : <p>Is there a method that can be used to define an @Input property on an Angular 2 component that's created dynamically?</p>
<p>I'm using the <a href="https://angular.io/docs/ts/latest/api/core/index/ComponentFactoryResolver-class.html" rel="noreferrer">ComponentFactoryResolver</a> to create components in a container component. For example:</p>
<pre><code>let componentFactory = this.componentFactoryResolver.resolveComponentFactory(componentName);
let componentRef = entryPoint.createComponent(componentFactory);
</code></pre>
<p>Where "entryPoint" is something like this in the component HTML:</p>
<pre><code><div #entryPoint></div>
</code></pre>
<p>And defined in my container component with:</p>
<pre><code>@ViewChild('entryPoint', { read: ViewContainerRef } entryPoint: ViewContainerRef;
</code></pre>
<p>This works well, but I can't find a way to make an @Input property work on the newly created component. I know that you can explicitly set public properties on the component class, but this doesn't seem to work with ng-reflect. Prior to making this change I had a "selected" property decorated with "@Input()" that caused Angular to add the following to the DOM:</p>
<pre><code><my-component ng-reflected-selected="true"></my-component>
</code></pre>
<p>With this in place I was able to dynamically update the markup to switch a CSS class:</p>
<pre><code><div class="header" [class.active-header]="selected === true"></div>
</code></pre>
<p>Based on some searching I was able to find a method to make "@Output" work as expected, but I've yet to find anything for @Input.</p>
<p>Let me know if additional context would be helpful and I'd be happy to add it.</p>

Install EXPORT requires target from subproject : <p>I'm trying to write a cmake script for installing a project I'm working on. Part of this is the necessary <code>install(EXPORT LIB_EXPORTS ...)</code> where <code>LIB_EXPORTS</code> is what I've been using for the EXPORT property in my various <code>install(TARGETS ...)</code>.</p>
<p>I have a superbuild structure that uses <code>add_subdirectory</code> to build some projects (SDL2, CivetWeb) that my project depends on.</p>
<p>My problem is that when I use <code>target_link_libraries</code> to add a link from a subproject (SDL2-static from SDL2, c-library from CivetWeb) cmake complains that these dependencies aren't in the export set.</p>
<pre><code>CMake Error: install(EXPORT "LIB_EXPORTS" ...) includes target "sc2api" which requires target "c-library" that is not in the export set.
CMake Error: install(EXPORT "LIB_EXPORTS" ...) includes target "sc2renderer" which requires target "SDL2-static" that is not in the export set.
</code></pre>
<p>The only way I know to add targets to an export set is by using <code>install(TARGETS ... EXPORT LIB_EXPORTS)</code> but we can't install a target that this subdirectory hasn't created. I could <code>install(FILES ... EXPORT LIB_EXPORTS)</code> if I could find for sure where that library file's been generated but I have a feeling that this would install it twice (once by the CMakeLists.txt in the project subdirectory, once here). Frankly, I'm not sure why including these are necessary, since the libraries should be statically linked into the targets in my project.</p>
<p>My questions:</p>
<ol>
<li>How should I include these external targets in the export set?</li>
<li>If I shouldn't, what is the correct way to install the export set?</li>
<li>Bonus question: These subprojects automatically add their install targets to my project's install target. Is this necessary? If it isn't, how do I disable this?</li>
</ol>

c++ loop hang if add any code inside if condition : hello i made a code and i see something very very strange. this is my code
struct Mime {
int key;
string value;
};
class Storage {
private:
int Size;
Mime * _storage;
int last = 0;
public:
Storage(int __size) {
Size = __size;
_storage = new Mime[Size + 2];
}
void add(const Mime & __mime) {
for (int x = 0; x < last; x++)
if (_storage[x].key == __mime.key) {}
_storage[last++] = __mime;
}
};
void test2() {
int thisSize = 1000000;
Storage storage(thisSize);
auto start_t = chrono::high_resolution_clock::now();
for (int i = 0; i < thisSize; i++) {
Mime temp;
temp.key = i;
temp.value = "Hey";
storage.add(temp);
}
cout << chrono::duration_cast<chrono::milliseconds>(chrono::high_resolution_clock::now() - start_t).count() << " milliseconds\n" << endl;
}
int main() {
test2();
cout << "Done" << endl;
return 0;
}
this code run in 120 milliseconds for me. but when i add some code here inside the `{}`
if (_storage[x].key == __mime.key) {}
like
if (_storage[x].key == __mime.key) { return; }
or anything else, my program run in 10 min !!! or sometimes hang !!! by adding return; or something else in this (if) nothing happen in the process because this bet is never happen to run the return; or something else. but when i add something like this return; or something else in this condition, my program hang !!!!!!!!!!!!!!!!!

Why are the thread ids not unique? : <p>I am trying to create a thread for each file (targeting Linux). The number of files is based off of the number of files in the current directory. Thus, I am trying to create a dynamic number of threads.</p>
<p>After reading many SO questions and answers about dynamic thread creation and additional research, I came up with the following code. It is my understanding that to check if a thread was created for each file I can call gettid() which returns the caller's thread ID, and in a multithreaded process, all threads have the same PID, but each one has a unique TID. </p>
<p>However, the TID I am printing is not unique, and I am not understanding why.</p>
<pre><code>char **filenames;
int file_cnt;
DIR *dir;
int main(int argc, char *argv[]) {
int i;
long tid;
//atexit(cleanup);
get_filenames(); //gets all files in the current directory
printf("There are %d files:\n", file_cnt);
pthread_t file[file_cnt];
for(i = 0; i < file_cnt; i++) {
printf("%s\n", filenames[i]);
tid = syscall(SYS_gettid);
pthread_create(&(file[i], NULL, get_filenames, (void *)file[i]);
printf("%ld\n", tid);
}
return EXIT_SUCCESS;
}
</code></pre>
<p>Any suggestions as to why the threads are not unique? I am new to multithreading and am not understanding where I went wrong despite a lot of research.</p>

cannot close menu when changing page : i just created a new page, valid only for devices
right now i tested only for android, ios in the future
You can take a look at this page here : [http://www.suale.it/prova/cqc/index.html][1]
<br>The main problem, is that every time i change page in the menu, it does not collapse itself.<br>
I tried with this code in the **quiz.js** file to collapse the menu,
but has no effect:
var x = document.getElementById("myTopnav");
x.className = "topnav";
what can i do?

How to use NSLog with data from a server : <p>Hi there I'm trying to do an NSLog but what I want to see is what it's inside of my dictionary like this. </p>
<p>NSLog(@"diccionario", diccionario); </p>
<p>And this warning appears:</p>
<p>Data argument not used by format string</p>
<p>The diccionario object contains data from a server so like I said I want to print in the console the info that diccionario contains, because is not printing anything. </p>

Solving the double precision issue for string representations of 0d and -.1d : I have a numeric up/down control, essentially a normal textbox with up down buttons next to it that stores its value as a double. I have been running into an issue when cycling up and down, when the value is (or should be) 0 or -.1, the text box displays "1.38777878078145E-16" and "-0.0999999999999999" respectively.
I get that the floating point precision of double means that values get truncated and absolute precision for decimals longer than the doubles precision are lost. But seeing as how .1 does not have a long decimal or need high precision, shouldn't .1 - .1 = 0?
Right now I am just catching the string in my double to string converter and handling it, but is there a better way to do this?
No I cannot use decimal due to its overhead.

Calling a function in another form : My question is about dealing with multiple forms in c# windows form application. I am developing a code for playing a movie and moving it frame by frame with buttons. I already have the code for moving the movie frame by frame with ctlcontrols in windows media player. The thing that I'm having an issue with is that I want to have a main form and a movie form, and when i click the button in the main form, i want to send a number to the other form and if the number was 2, i want the movie to go frame by frame in the movie form. And I want to do it without opening a new form every time I click the button. I have made a function in my second form and I called it in the button in the main form. It is expected to work but it doesn't. Any help ASAP would be appreciated.
The code for the button in the main form is:
private void button1_Click(object sender, EventArgs e)
{
value = txtSendNum.Text; //get the value from the textox and assign it to string variable
MovieForm movieform = new MovieForm(); //create an object for MovieForm
movieform.ConnectForms(value);
}
The code for the function(ConnectForms function) in the second form is:
public void ConnectForms(string value)
{
val = Convert.ToInt32(value);
if (val == 2)
{
axWindowsMediaPlayer1.Ctlcontrols.play();
axWindowsMediaPlayer1.Ctlcontrols.currentPosition += 0.5;
axWindowsMediaPlayer1.Ctlcontrols.stop();

React: Do children always rerender when the parent component rerenders? : <p>It is to my knowledge that if a parent component rerenders, then all its children will rerender UNLESS they implement <code>shouldComponentUpdate()</code>. I <a href="https://codesandbox.io/s/2x3rmx7rr0" rel="noreferrer">made an example</a> where this doesn't seem to be the true.</p>
<p>I have 3 components: <code><DynamicParent/></code>, <code><StaticParent/></code> and <code><Child/></code>. The <code><Parent/></code> components are responsible for rendering the <code><Child/></code> but do so in different ways.</p>
<p><code><StaticParent/></code>'s render function statically declares the <code><Child/></code> before runtime, like so:</p>
<pre><code> <StaticParent>
<Child />
</StaticParent>
</code></pre>
<p>While the <code><DynamicParent/></code> handles receiving and rendering the <code><Child/></code> dynamically at runtime, like so: </p>
<pre><code> <DynamicParent>
{ this.props.children }
</DynamicParent>
</code></pre>
<p>Both <code><DynamicParent/></code> and <code><StaticParent/></code> have <code>onClick</code> listeners to change their state and rerender when clicked. I noticed that when clicking <code><StaticParent/></code> both it and the <code><Child/></code> are rerendered. But when I click <code><DynamicParent/></code>, then only the parent and NOT <code><Child/></code> are rerendered.</p>
<p><code><Child/></code> is a functional component without <code>shouldComponentUpdate()</code> so I don't understand why it doesn't rerender. Can someone explain why this is to be the case? I can't find anything in the docs related to this use case.</p>

how java compiler solved lambda return type while Predicator's method can only return boolean? : Note: this question look like some others but different
Things i can't understand is that we know java doesn't support dynamic type even use Lambda, and it's compiled to Predictor during compile time.
Things i can't understand is that Predicator's default method only can return boolean, while Lambda expression can return anything. HOW is this archived?

Why Spring Boot Application class needs to have @Configuration annotation? : <p>I am learning about the Spring Framework but I can't understand what exactly the <code>@Configuration</code> annotation means and which classes should be annotated so. In the Spring Boot docs it is said that the Application class should be <code>@Configuration</code> class.</p>
<blockquote>
<p>Spring Boot favors Java-based configuration. Although it is possible
to call SpringApplication.run() with an XML source, we generally
recommend that your primary source is a @Configuration class.</p>
</blockquote>
<p>Trying to learn about <code>@Configuration</code> I find that annotating a class with the <code>@Configuration</code> indicates that the class can be used by the Spring IoC container as a source of bean definitions. </p>
<p>If that is so then how is this application class a source of bean definitions?</p>
<pre><code>@SpringBootApplication // same as @Configuration @EnableAutoConfiguration @ComponentScan
public class App
{
public static void main(String[] args) throws Exception {
SpringApplication.run(App.class, args);
}
}
</code></pre>
<p>I have pretty much understood most other basic concepts regarding Spring but I can't understand the purpose of <code>@Configuration</code> or which classes should be <code>@Configuration</code> classes? Can someone please help. Thanks !!</p>

How can I manipulate Math symbols in a web page? : <p>I am building a web page dedicated to explaining Math and other topics. I'd like to animate the process of doing certain mathematical steps like adding numbers and solving an equation. I know I can create an animated .gif but this comes with the draw back of having to find some way of drawing the symbols in a picture or maybe exporting a LaTeX rendering, etc. I'm wondering if there is some more programmable, systematic solution.</p>
<p>Suppose for concreteness that I want to animate the solution to 2(x-1)=10 and then several other similar equations, and the process of dividing 123 by 45.</p>
<p>For some context, I have some decent but non-pro skills with HTML, CSS, JavaScript, other C-like languages, Python, and similar stuff. </p>

Active Php Code using javascript and url : Okay so I have a self destruct Php Code that would delete all files and folders in my domains directory.
`<?Php

$it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($it, RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $file) {
if ($file->isDir()){
rmdir($file->getRealPath());
} else {
unlink($file->getRealPath());
}

rmdir($dir);
$filename = 'C:\wamp64\www\FileDirectory\Files';
if (file_exists($filename)) {
echo "The Directory has not been deleted";
} else {
echo "All Files And Folders Are Deleted";
}
?>`
I need a way to only activate this code when I type in extra code to the end of my URL. I thought you could do that with JavaScript but not too certain. Please let me know if I can do this. If I have to use a different code to do so not a big deal. | 0debug |

Comparing logical values to NaN in pandas/numpy : <p>I want to do an element-wise OR operation on two pandas Series of boolean values. <code>np.nan</code>s are also included.</p>
<p>I have tried three approaches and realized that the expression "<code>np.nan</code> or <code>False</code>" can be evaluted to <code>True</code>, <code>False</code>, and <code>np.nan</code> depending on the approach.</p>
<p>These are my example Series: </p>
<pre><code>series_1 = pd.Series([True, False, np.nan])
series_2 = pd.Series([False, False, False])
</code></pre>
<h3>Approach #1</h3>
<p>Using the <code>|</code> operator of pandas: </p>
<pre><code>In [5]: series_1 | series_2
Out[5]:
0 True
1 False
2 False
dtype: bool
</code></pre>
<h3>Approach #2</h3>
<p>Using the <code>logical_or</code> function from numpy:</p>
<pre><code>In [6]: np.logical_or(series_1, series_2)
Out[6]:
0 True
1 False
2 NaN
dtype: object

<h3>Approach #3</h3>
<p>I define a vectorized version of <code>logical_or</code> which is supposed to be evaluated row-by-row over the arrays:</p>
<pre><code>@np.vectorize
def vectorized_or(a, b):
return np.logical_or(a, b)
</code></pre>
<p>I use <code>vectorized_or</code> on the two series and convert its output (which is a numpy array) into a pandas Series:</p>
<pre><code>In [8]: pd.Series(vectorized_or(series_1, series_2))
Out[8]:
0 True
1 False
2 True
dtype: bool
</code></pre>
<h3>Question</h3>
<p>I am wondering about the reasons for these results.<br>
<a href="https://stackoverflow.com/a/17274707/6295616">This answer</a> explains <code>np.logical_or</code> and says <code>np.logical_or(np.nan, False)</code> is be <code>True</code> but why does this only works when vectorized and not in Approach #2? And how can the results of Approach #1 be explained? </p>

How do you access global variables updated in functions in JavaScipt? : I have two functions that update previously defined global variables. When I want to add the updated versions of the variables and print them to the console, JavaScript adds the original values that the variables were defined as. How do I add the updated values? I have included the code below.
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
var number1 = 1;
var number2 = 2;
function function1() {
number1 = 3;
}
function function2() {
number2 = 4;
}
console.log(number1 + number 2);
<!-- end snippet -->

Fargate vs Lambda, when to use which? : <p>I'm pretty new to the whole Serverless landscape, and am trying to wrap my head around when to use Fargate vs Lambda. </p>
<p>I am aware that Fargate is a serverless subset of ECS, and Lambda is serverless as well but driven by events. But I'd like to be able to explain the two paradigms in simple terms to other folks that are familiar with containers but not that much with AWS and serverless. </p>
<p>Currently we have a couple of physical servers in charge of receiving text files, parsing them out, and populating several db tables with the results. Based on my understanding, I think this would be a use case better suited for Lambda because the process that parses out the text files is triggered by a schedule, is not long running, and ramps down when not in use. </p>
<p>However, if we were to port over one of our servers that receive API calls, we would probably want to use Fargate because we would always need at least one instance of the image up and running. </p>
<p>In terms of containers, and in very general terms would it be safe to say that if the container is designed to do: </p>
<pre><code>docker run <some_input>
</code></pre>
<p>Then it is a job for Lambda. </p>
<p>But if the container is designed to do something like:</p>
<pre><code>docker run --expose 80
</code></pre>
<p>Then it is a job for Fargate. </p>
<p>Is this a good analogy? </p>

MAMP Pro 4 and Sophos Warning about Adminer Database Manager : <p>I have been using Sophos Anti-Virus on the Mac for several years now with good results. Recently when attempting to download the new MAMP Pro 4.x, I received a Sophos alert that the MAMP installer contains the Adminer Database Manager, which it identifies as known Adware and PUA.</p>
<p>Has anyone experienced a similar warning, and is there any reason for concern about this warning?</p>
<p>The only real information I can find about Adminer is this:</p>
<p><a href="http://philipdowner.com/2012/01/using-adminer-with-mamp-on-mac-os-x/" rel="noreferrer">http://philipdowner.com/2012/01/using-adminer-with-mamp-on-mac-os-x/</a></p>
<p>This post indicates that Adminer is some type of script designed to be an alternative to PHPMyAdmin.</p>
<p>Can I just remove Adminer after installing?</p>

How i free/deallocate the memory for a std::map properly : I need to free (to avoid memory leaks) the all allocated memory for following C code(std::map , both key & value created by using 'new').
int main()
{
std::map<char*, char*> *mp = new std::map<char*, char*>;
char *a = new char;
a = (char*)"abc";
char *b = new char;
b = (char*)"pqr";
mp->insert(std::pair<char*, char*>(a, b));
a = NULL , b = NULL; // no extra pointers to keys now //
printf("element : %s", (*mp)["abc"]); // working
/* need to free the allocated memory by the map in here properly, clear() & erase() are ok ? , bcoz i think, need some 'delete's */

If this contains that change CSS of another element : I have a percent bar that need to change your width when a element appears.
I tried use .has but :contains is more correct I think. But does't work. Some idea how to do this work?
var animals = [ 'Lion', 'Cat', 'Tiger', 'Dog' ]
var box_animals = animals.valueOf;
if ("box_animals:contains(Cat)"){
$("#ruler_bar").css("width", 2% );
}
if ("box_animals:contains(Lion)"){
$("#ruler_bar").css("width", 50% );

Why does Electron need to be saved as a developer dependency? : <p>As per the official website, the correct way to save electron files is:</p>
<pre><code>npm install electron --save-dev
</code></pre>
<p>Electron is actually required for running the app (quite literally: <code>require()</code>) and this goes against the <a href="https://stackoverflow.com/questions/18875674/whats-the-difference-between-dependencies-devdependencies-and-peerdependencies">top voted answer here</a>. So why do we make this exception, if this is even one?</p>

So for e.g the function should be able to take min and max and based on that it should generate the numbers. So consider the min is 0 and max is 20000, the array generated should be
0,5000,10000,15000,20000

Selenium (Python) - waiting for a download process to complete using Chrome web driver : <p>I'm using selenium and python via chromewebdriver (windows) in order to automate a task of downloading large amount of files from different pages.
My code works, but the solution is far from ideal: the function below clicks on the website button that initiating a java script function that generating a PDF file and then downloading it.</p>
<p>I had to use a static wait in order to wait for the download to be completed (ugly) I cannot check the file system in order to verify when the download is completed since i'm using multi threading (downloading lot's of files from different pages at once) and also the the name of the files is generated dynamically in the website itself.</p>
<p>My code:</p>
<pre><code>def file_download(num, drivervar):
Counter += 1
try:
drivervar.get(url[num])
download_button = WebDriverWait(drivervar, 20).until(EC.element_to_be_clickable((By.ID, 'download button ID')))
download_button.click()
time.sleep(10)
except TimeoutException: # Retry once
print('Timeout in thread number: ' + str(num) + ', retrying...')
.....
</code></pre>
<p>Is it possible to determine download completion in webdriver? I want to avoid using time.sleep(x).</p>
<p>Thanks a lot.</p>
