Customise ng serve to proxy calls to /api? : <p>I created a new application with ng CLI, works like a charm:
<code>
ng new babysteps
cd babysteps
ng serve
</code>
ng serve uses webpack to assemble the app. To fully test it, I need to serve <code>/api...</code> from my API mock server (specifically the POST requests). How can I customise the web server used, to redirect that one URL pattern?</p>
<p>The Webpack dev server has <a href="https://webpack.github.io/docs/webpack-dev-server.html" rel="noreferrer">a proxy setting</a>, but it seems (?) <code>ng serve</code> doesn't have a config file (or I didn't get).</p>
<p>Do I need to create a <code>webpack.config.js</code> or create/edit some other file to proxy ?</p>

How to create a 3rd column based on 2 columns from two tables [inner and outer join] : <ul>
<li>I have a lot of rows in 'table alpha' where some of these rows occurs in 'table beta' as well.</li>
<li>Both row alpha and beta have a date column.
<ul>
<li>However, when i select both date columns the rows from table alpha <strong>that do not occur</strong> in row B will have a null-value assigned to them.</li>
</ul></li>
</ul>
<blockquote>
<p>My problem is that I want to make a third date-column that will use the dates from table <em>beta</em> <strong>if they are not null</strong>. If they are null, it should use the dates from table alpha.</p>

whenever I try this it does not work(input = 6), it sends me to the previous menu and says the input is invalid.

c++ : invoking tcl proc from c++ in multithreaded mode : I am working in c++.
My function func() is being called by multiple threads. ( each thread will call this function only once)
From inside the func(), I want each thread to call a TCL proc named tcl_proc_name ( which takes no arguments )
For this, I did like this
Tcl_Eval( Tcl_CreateInterp() , “tcl_proc_name”);
But it somehow this code is not able to invoke the tcl proc.
Is I’am missing something. Please help.
Regards

Why there are two buttons in GUI Configure and Generate when CLI does all in one command : <p>I understand that cmake is build generator. It mean that it can generate appropriate builds (makefiles, Visual Studio project etc.) based on instructions from CMakeLists.txt. But I do not understand two things which I guess are related:</p>
<ol>
<li><p>Why there are two buttons "Configure" and "Generate" in cmake-gui? In command line tutorials that I've read (e.g. <a href="http://derekmolloy.ie/hello-world-introductions-to-cmake/" rel="noreferrer">this one</a>) usual process was done with one <code>cmake</code> command.</p></li>
<li><p>What is cache in cmake world? AFAIK it is state when "Configure" button was pressed but "Generate" button was not pressed. But why is this useful? What all those variables that pops-up after pressing "Configure" mean? Why I'm supposed to edit them? Isn't the only allowed configuration done via CMakeLists.txt?</p></li>
</ol>
<p>Thanks</p>

Why is regex search slower with capturing groups in Python? : <p>I have an application code which generates regexes dynamically
from a config for some parsing.
When timing performance of two variations, the regex variation
with each part of an OR regex being captured is noticably slow than
a normal regex.
The reason would be overhead of certain operations internally in regex module.</p>
<pre><code>>>> import timeit
>>> setup = '''
... import re
... '''
#no capture group
>>> print(timeit.timeit("re.search(r'hello|bye|ola|cheers','some say hello,some say bye, or ola or cheers!')", setup=setup))
0.922958850861
#with capture group
>>> print(timeit.timeit("re.search(r'(hello)|(bye)|(ola)|(cheers)','some say hello,some say bye, or ola or cheers!')", setup=setup))
1.44321084023
#no capture group
>>> print(timeit.timeit("re.search(r'hello|bye|ola|cheers','some say hello,some say bye, or ola or cheers!')", setup=setup))
0.913202047348
# capture group
>>> print(timeit.timeit("re.search(r'(hello)|(bye)|(ola)|(cheers)','some say hello,some say bye, or ola or cheers!')", setup=setup))
1.41544604301
</code></pre>
<p><strong>Question:</strong> What causes this considerable drop in performance when using capture groups ? </p>

how do i display the output from for loop as a table in php : my output is in the form of a 2d array. i have uploaded a sample file and the output is displayed like a paragraph. i want it to be displayed as a table.
code:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-html -->
<?php
require("reader.php"); // php excel reader
$file="sample.xls";
$connection=new Spreadsheet_Excel_Reader(); // our main object
$connection->read($file);
$startrow=1;
$endrow=1000;
for($i=$startrow;$i<$endrow;$i++){ // we read row to row
for($j=1;$j<=30;$j++)
{
echo $connection->sheets[0]["cells"][$i][$j]; // so we get [2][3] and [3][3]
echo "\n";
}
echo "\n";
}

CompletableFuture in the Android Support Library? : <p>So I was migrating an Android Studio project to Java 8, Android API level 24 and the Jack toolchain today to check out the new features, especially lambdas and <code>CompletableFuture</code>. </p>
<p>Unfortunately, <code>CompletableFuture</code> seems to be available only from API level 24 on (my minimum API level for that project being 16). </p>
<p>Do you know of any plans on bringing <code>CompletableFuture</code> to the Android support library? It looks like a nice solution for the Promises pattern.</p>

What is the reached end of file while parsing error, and how can I avoid this error in the future? : My question is very simple. I am just wondering what the reached end of file while parsing error actually means / is. Why this error actually occurs. In addition, how I could avoid it. Before you say that this is a duplication of question it really isn't because most questions I looked at are just examples with code. That is not what I am looking for I am just looking for a clear cut answer of why this error happens what it is / means, and how to avoid it that is it.
NOTE: Thank you very much, all help is appreciated! If you are thinking about downvoting because of the quality of the question, please ask the question or suggest how I could make this question better before going and downvoting the question. Thank you so much, I hope you have a very great evening. Hopefully, you can answer this question quickly and very efficiently!

<p>The value of the variable a and myDict will change since both user defined class and dictionary are mutable types. Is there ant method that just pass the value of the variable so that the variable itself won't change? If there are multiple ways, please let me know all of them. Thank you very much.</p>

GCC 7, -Wimplicit-fallthrough warnings, and portable way to clear them? : <p>We are catching warnings from GCC 7 for implicit fall through in a switch statement. Previously, we cleared them under Clang (that's the reason for the comment seen below):</p>
<pre><code>g++ -DNDEBUG -g2 -O3 -std=c++17 -Wall -Wextra -fPIC -c authenc.cpp
asn.cpp: In member function ‘void EncodedObjectFilter::Put(const byte*, size_t)’:
asn.cpp:359:18: warning: this statement may fall through [-Wimplicit-fallthrough=]
m_state = BODY; // fall through
^
asn.cpp:361:3: note: here
case BODY:
^~~~
</code></pre>
<p>The <a href="https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html" rel="noreferrer">GCC manual</a> states to use <code>__attribute__ ((fallthrough))</code>, but its not portable. The manual also states <em>"... it is also possible to add a fallthrough comment to silence the warning"</em>, but it only offer <code>FALLTHRU</code> (is this really the only choice?):</p>
<pre><code>switch (cond)
{
case 1:
bar (0);
/* FALLTHRU */
default:
…
}
</code></pre>
<p>Is there a portable way to clear the fall through warning for both Clang and GCC? If so, then what is it?</p>

how to remove lines in OpenCV : I want to remove lines and keypoints. I just want to remain a green rectangular.
Is there a function except for drawMatches or can I make lines and keypoints invisible in drawMatches?

drawMatches( img_object, keypoints_object, img_scene, keypoints_scene,
good_matches, img_matches, Scalar::all(-1), Scalar::all(-1),
std::vector<char>(), DrawMatchesFlags::NOT_DRAW_SINGLE_POINTS );

how to get innerHTML value in java code : I want to change table <td> data by using innerHTML property.
But after applying innerHTML property those values set in <TD> but not
accessible in java code
So is there any alternative to innerHTML property so that value can be set inv<td>
and it can also be accessed in Java Code.
in java script i am using following code.
<script>
var row=0,col=0,i=1;//can be used in loop
document.getElementById("tableID").rows[row].cells[col].innerHTML=i;

how to shortcut a coroutine in unity C#? : I write a coroutine to do a batch work every frame, I have no problem to start it, but, I want to short-cut the execution when specific condition meets.
Such as :
public IEnumerator workCoroutine(){
int i = 0;
if(GLOBAL_LOCK){
return; //will not work here.
//we will not execute this coroutine further more, ie,shortcut it;
//but how to ?
}
while( i<=1000){
doingSomeWorkHere(i);
i++;
yield return null;
}
}
I know maybe I could do this by:
public IEnumerator workCoroutine(){
int i = 0;
if(!GLOBAL_LOCK){
while( i<=1000){
doingSomeWorkHere(i);
i++;
yield return null;
}
}
}
But I think this way may cause the code to be ugly when there are multi conditions.
So is there a way to shortcut the coroutine?

How does the global variable behave inside function(Python) : <p>Case 1</p>
<pre><code>A = '213'
def wow():
print(A)
wow()
Output: '213'
</code></pre>
<p>Case 2</p>
<pre><code>A = '213'
def wow():
print(A)
A = 12
wow()
Output: UnboundLocalError: local variable 'A' referenced before assignment
</code></pre>
<p>I'd thought that the output in the case 2 would be identical to the case 1, since A is a global variable and I called "print(A)" <em>before</em> reassigning value to A within the function. So my question is, why in the case 1 calling A is perfectly fine, but case 2 throws error?</p>

Are all final variables captured by anonymous classes? : <p>I thought I knew the answer to this, but I can't find any confirmation after an hour or so of searching.</p>
<p>In this code:</p>
<pre><code>public class Outer {
// other code
private void method1() {
final SomeObject obj1 = new SomeObject(...);
final SomeObject obj2 = new SomeObject(...);
someManager.registerCallback(new SomeCallbackClass() {
@Override
public void onEvent() {
System.out.println(obj1.getName());
}
});
}
}
</code></pre>
<p>Assume that <code>registerCallback</code> saves its parameter somewhere, so that the object of the anonymous subclass will live for a while. Obviously this object has to maintain a reference to <code>obj1</code> so that <code>onEvent</code> will work if it is called.</p>
<p>But given that the object doesn't use <code>obj2</code>, does it still maintain a reference to <code>obj2</code>, so that <code>obj2</code> can't be garbage-collected while the object lives? I was under the impression that <em>all</em> visible <code>final</code> (or effectively final) local variables and parameters were captured and thus couldn't be GC'ed as long as the object was alive, but I can't find anything that says one way or the other.</p>
<p>Is it implementation-dependent?</p>
<p>Is there a section in the JLS that answers this? I wasn't able to find the answer there.</p>

Slow len function on dask distributed dataframe : <p>I have been testing how to use dask (cluster with 20 cores) and I am surprised by the speed that I get on calling a len function vs slicing through loc.</p>

from dask.distributed import Client
client = Client('192.168.1.220:8786')
log = pd.read_csv('800000test', sep='\t')
logd = dd.from_pandas(log,npartitions=20)
#This is the code than runs slowly
#(2.9 seconds whilst I would expect no more than a few hundred millisencods)
print(len(logd))
#Instead this code is actually running almost 20 times faster than pandas
logd.loc[:'Host'].count().compute()
</code></pre>
<p>Any ideas why this could be happening? It isn't important for me that len runs fast, but I feel that by not understanding this behaviour there is something I am not grasping about the library.</p>

How can I use all entities instead of listing them all individually (Symfony)? : In my Controller I list all entities I have:
use App\Entity\Members;

use App\Entity\Projects;
But because new Entities will automatically be created, I need instead something like
use AllEntities;
Is this possible?

<p>I apply PCA to my data to reduce the dimensionality to 3. It means now I have 3 principal components where each PC is a new variable. Now I want to know which feature among A, B, C, D, E is most important, which is the 2nd most important feature and so on and by how much (such as in terms of score).</p>
<p>I know that the first PC has the highest variance(importance), followed by 2nd, followed by 3rd and so on but I want the importance among original features A, B, C, D, E. Is there any method to find it?</p>

How to make ffmpeg available inside my Docker container? : <p>I'm currently trying to run a <code>ffmpeg</code> Docker image inside my own container with <code>docker-compose</code> using the <code>depends_on</code> clause. But when I try to reach <code>ffmpeg</code> inside my code, it seems like it's not available system-wide and I get an error. I believe I'm misconfiguring Docker.</p>
<p>My current <code>Dockerfile</code> is as follows:</p>
<pre><code>FROM node:9
WORKDIR /usr/app
COPY package*.json ./
RUN npm install --quiet
COPY . .
</code></pre>
<p>And my <code>docker-compose.yml</code>:</p>
<pre><code>version: '3'
services:
app:
build: .
command: npm run dev
volumes:
- .:/usr/app/
- /usr/app/node_modules
ports:
- "3000:3000"
depends_on:
- ffmpeg
ffmpeg:
image: jrottenberg/ffmpeg:3.3
</code></pre>
<p>When I run <code>docker-compose up</code> I can see that the <code>ffmpeg</code> is actually working, but then my application proceeds to start and it seems that <code>ffmpeg</code> ceases to work.</p>

C# Declaration of Class for use as List : I'm trying to declare this item for use as a list.
class Item

Public long Offset{ get;set; }
Public int Value{ get;set; }
}
I thought this would be ok, I copied it off someone else, but I don't understand what get and set do. I'm completely new to C#, but the tutorial I watched put their class declaration in a different file - do you have to do that?
I get this error : "Line: 15 Column: 11 (CS1519) Invalid token 'int' in class, struct, or interface member declaration"

C++ unique_ptr initialization through constructor : <p>I have simple (I suppose) problem with my C++ code. Each time I initialize unique_ptr through constructor I'm getting the same problem: </p>
<blockquote>
<p><strong>munmap_chunk(): invalid pointer: 0x00007ffc40ba6bf0</strong></p>
</blockquote>
<p>Here's the code:</p>
<p>1) Private part of the class:</p>
<pre><code>template<typename T>
class Node{
typedef std::unique_ptr<Node> ptr;
T value;
ptr left, right;
</code></pre>
<p>2) Constructor initializing ptr left and ptr right:</p>
<pre><code>explicit Node(const T value, Node* left = nullptr, Node* right = nullptr):
value{value}, left{left}, right{right} {}

<p>What is the problem here? Thanks for clarification or pointing me in the right direction. </p>

Can I install python 3.7 in ubuntu 18.04 without having python 3.6 in the system? : <p>Please read the question carefully before closing as duplicate, I believe the use case to be unique.</p>
<p>I'm trying to create a docker image that <strong>only has python 3.7 installed</strong>, the problem is that if I try to install pip, the command also installs python 3.6 which <strong>I do not want</strong>.</p>
<p>The relevant part of the ideal docker file I'm tinkering is as follows</p>
<pre><code>FROM ubuntu:18.04
# Upgrade installed packages
RUN apt-get update && apt-get upgrade -y && apt-get clean
# (...)
# Python package management and basic dependencies
RUN apt-get install -y python3.7 python3.7-dev python3.7-pip
# Register the version in alternatives
RUN update-alternatives --install /usr/bin/python python /usr/bin/python3.7 1
# Set python 3 as the default python
RUN update-alternatives --set python /usr/bin/python3.7
# Upgrade pip to latest version
RUN python -m ensurepip --upgrade
# (...)
</code></pre>
<p>This would fail as <em>python3.7-pip</em> doesn't seem to exist; only <em>python3-pip</em> does, which is what installs python 3.6 for some reason.</p>
<p>I tried not installing pip at all and doing it manually, like so</p>
<pre><code># (...)
RUN apt-get install -y python3.7 python3.7-dev
# (...)
RUN curl 'https://bootstrap.pypa.io/get-pip.py' > get-pip.py
RUN python get-pip.py pip --no-setuptools --no-wheel
</code></pre>
<p>Which fails with this error:</p>
<pre><code>Traceback (most recent call last):

Anti Forgery Token race condition : <p>I have an MVC view that is supposed to be iFramed. And several instances of it might be iFramed in the same host page. In my view I have this:</p>
<pre><code>@Html.AntiForgeryToken()
</code></pre>
<p>Which I use to try to make sure calls to a web api are only coming from this page. My host page might look something like this:</p>
<pre><code><iframe src="http://myserver.com/myview?someparameters=0000"></iframe>
<iframe src="http://myserver.com/myview?someparameters=0001"></iframe>
<iframe src="http://myserver.com/myview?someparameters=0002"></iframe>
</code></pre>
<p>In my view I grab the token and submit it in a header so that I can check it in my API:</p>
<pre><code>var headers = actionContext.Request.Headers;
var headerToken = headers.Contains("__RequestVerificationToken") ? headers.GetValues("__RequestVerificationToken").FirstOrDefault() : null;
var cookie = headers.GetCookies("__RequestVerificationToken").FirstOrDefault()?["__RequestVerificationToken"]?.Value;
AntiForgery.Validate(cookie,headerToken);
</code></pre>
<p>The problem I'm running into is that in my host page, all three views are getting loaded in parallel. As a result they all get their own random token in a hidden field and try to set the cookie. But while there can be three separate independent hidden input tokens, there can be only one cookie. So of the three requests, two will fail and one will succeed. A reload of the page will have all three working again, presumably because they are all getting the same anti-forgery token at this point (because it belongs to the session - if I understand this correctly).</p>
<p>So how can I avoid this? How can I make sure they all get the same token?</p>

this is the code in vector
```
// CLASS TEMPLATE _Vector_const_iterator
template <class _Myvec>
class _Vector_const_iterator : public _Iterator_base {
public:
...
#if _ITERATOR_DEBUG_LEVEL != 0
friend void _Verify_range(const _Vector_const_iterator& _First, const _Vector_const_iterator& _Last) {
_STL_VERIFY(_First._Getcont() == _Last._Getcont(), "vector iterators in range are from different containers");
_STL_VERIFY(_First._Ptr <= _Last._Ptr, "vector iterator range transposed");
}
#endif // _ITERATOR_DEBUG_LEVEL != 0
...
}
```
the compiler seems only try to match this three prototype function:
```
void std::_Verify_range(const std::_Array_const_iterator<_Ty,_Size> &,const std::_Array_const_iterator<_Ty,_Size> &);
and
void std::_Verify_range(const std::reverse_iterator<_BidIt> &,const std::reverse_iterator<_BidIt2> &)
and
void std::_Verify_range(const _Ty *const ,const _Ty *const ) noexcept;
```

how to know the depth of a git's shallow clone? : <p>If I retrieve a shallow clone, e.g.</p>
<pre><code>git clone --depth 10 http://foo.bar/baz.git
</code></pre>
<p>Does <code>git</code> have any command to retrieve the depth of this clone? (e.g. a command that simply prints <code>10</code>).</p>

Choice Stack Between Meteor, Ionic 2, Firebase : <p>I'm brand new to coding (still consoliding my JS) and i have a project for a webiste + mobile app to help people with their diet. It will have a database with lots of recipe and people will be able to put their needs, the application will propose them list of groceries and recipe to suit their needs. The point is not to discuss the application, i know there is a lot out here about that.</p>
<p>What i would like to know is which solution will best suits my needs. I read about angular2 for the web application and ionic 2 for the mobile part, and i was planning to use firebase for the database. </p>
<p>BUT i recently learned that something called Meteor is doing all of this in one place.</p>
<p>I post this on stack to be sure that i understand correctly, so i'm wright or totally wrong ? </p>
<p>Thank you in advance for your help and i whish you all a good day !</p>

I am new to Python. While coding an error of name not defined is generated. Can anyone help me with this? : I was coding for the question--Write a Python function that takes two lists and returns True if they have at least one common member
code:
first = [a,b,c,d,e,f]
second = [a,s,d,f,g,h]
for word1 in first:
for word2 in second:
if word1==word2:
print("success")
Error:
first = list[a,b,c,d,e,f]
NameError: name 'a' is not defined
Can someone please help me with different errors faced while coding in python and what should be the best approach towards it?
Thanks,
