How to add fonts for different font weights for react-native android project? : <p>I've managed to add a custom font by:</p>
<ul>
<li><p>putting *.ttf files in <code>ProjectName/android/app/src/main/assets/fonts/</code> like this:</p>
<ul>
<li>Open Sans.ttf</li>
<li>Open Sans_italic.ttf</li>
<li>Open Sans_bold.ttf</li>
<li>Open Sans_bold_italic.ttf</li>
</ul></li>
<li><p>and setting font family by <code>fontFamily: "Open Sans"</code></p></li>
</ul>
<p>But there are extra font weights I want to use like 'Semi Bold', 'Extra Bold'. I tried adding them as 'Open Sans_900.ttf' and setting <code>fontWeight: 900</code> but that didn't work, it displayed bold version of the font.</p>
<p>Is there a way to add these additional font weights?</p>

Feature Importance with XGBClassifier : <p>Hopefully I'm reading this wrong but in the XGBoost library <a href="http://xgboost.readthedocs.io/en/latest/python/python_api.html#module-xgboost.sklearn" rel="noreferrer">documentation</a>, there is note of extracting the feature importance attributes using <code>feature_importances_</code> much like sklearn's random forest.</p>
<p>However, for some reason, I keep getting this error: <code>AttributeError: 'XGBClassifier' object has no attribute 'feature_importances_'</code></p>
<p>My code snippet is below:</p>
<pre><code>from sklearn import datasets
import xgboost as xg
iris = datasets.load_iris()
X = iris.data
Y = iris.target
Y = iris.target[ Y < 2] # arbitrarily removing class 2 so it can be 0 and 1
X = X[range(1,len(Y)+1)] # cutting the dataframe to match the rows in Y
xgb = xg.XGBClassifier()
fit = xgb.fit(X, Y)
fit.feature_importances_
</code></pre>
<p>It seems that you can compute feature importance using the <code>Booster</code> object by calling the <code>get_fscore</code> attribute. The only reason I'm using <code>XGBClassifier</code> over <code>Booster</code> is because it is able to be wrapped in a sklearn pipeline. Any thoughts on feature extractions? Is anyone else experiencing this?</p>

Regex for specific characters : <p>I'm trying to refactor this piece of code:</p>
<pre><code>if(!RenamePCTextBox.Text.Any(c => c == '\\' || c == '/' || c == ':' || c == '*' || c == '?' || c == '"' || c == '<' || c == '>' || c == '|' || c == '.' || c == ' ' || c == ',' || c == '~' || c == '!' || c == '@' || c == '#' || c == '$' || c == '%' || c == '^' || c == '&' || c == '\'' || c == '(' || c == ')' || c == '{' || c == '}' || c == '_' || c == '[' || c == ']') && !String.IsNullOrEmpty(RenamePCTextBox.Text))
{
LabelCanUsePCName.Content = "You can use this name";
LabelCanUsePCName.Foreground = Brushes.DarkGreen;
}
</code></pre>
<p>I would like to know if there is way to write it in regex expression? I think this code looks realy ugly this way. Or what would be better aproach for this?</p>
<p>I need to disable only characters above, another other character wanna leave for usage (like "-" for example).</p>

How can I download a file using copy through an ntlm proxy on php? : <p>I have a qemu linux virtual machine and I'm trying to install composer on it using the commands on the composer page. I'm on a windows network accessing the internet through a proxy that uses ntlm, so I use cntlm to authenticate linux and other programs on my PC (thanks to the people that created cntlm). I added the context to the copy command needed to access the proxy but it doesn't work.</p>
<p>This are the command used so far:</p>
<pre class="lang-bash prettyprint-override"><code>$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php', stream_context_create(['https' => ['proxy' => 'http://10.0.2.2:3128/']]));"
# a variant
$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php', stream_context_create(['https' => ['proxy' => 'tcp://10.0.2.2:3128/']]));"
</code></pre>
<p>The answer is:</p>
<pre class="lang-bash prettyprint-override"><code>PHP Warning: copy(https://getcomposer.org/installer): failed to open stream: Connection timed out in Command line code on line 1
</code></pre>
<p>Download the file using wget works fine. </p>
<pre class="lang-bash prettyprint-override"><code>$ env | grep "proxy"

Is there any JS method to parse date only by providing month and year as arguments? : <p>I'm working in a JavaScript date picker. I need to parse date by providing month and year. For example, if I'm giving argument as '01/2019', the output should be <code>Tue Jan 1 2019 00:00:00 GMT 05 30</code>. I'm aware this can be achieved by using <code>.toUTCString()</code> only if the argument should be a valid date i.e., it should be in the format of <code>dd mm yyyy</code>. But in my case, the format should be <code>mm yyyy</code>. Is there any JS built-in method to achieve this?</p>
<p><strong>Additional Info</strong>: Since date(dd) is not provided, the first date of the input month(mm) can be taken.
01/2019 - Tue Jan 1 2019 00:00:00 GMT 05 30</p>

why there is different output for below two codes? : <p>The below program outputs false</p>

<p>Shouldn't the output in first case be true? As while creating String s4="ab" there is already an object with value "ab" in the string constant pool.</p>

What is the most efficient way of freeing the memory allocated to a massive vector? : <p>I have a massive <code>std::vector<strc> V</code> filled with more than 100M elements, which I use as the input of some function <code>foo</code>. Here, <code>strc</code>
is simply a <code>struct</code> containing three primitives. After the call to <code>foo</code> finishes, I don't have any purpose for <code>V</code>, so I want to reclaim as much memory from it as possible. Clearly <code>V.clear()</code> doesn't do the job as <code>V</code> retains its capacity. </p>
<p>I have read some suggestion advocating for the trick <code>std::vector<strc>().swap(V)</code>, but it looks rather gimmicky an not good practice. I'm not even sure if it does what I need!. Is there a standard way of doing this? If indeed <code>swap</code> is the best option, should I call <code>clear</code> first? Since the complexity of <code>swap</code> is constant, it seems that <code>swap</code> is literally exchanging the address of <code>V</code> with that of an empty, nameless vector. Then, what happens with all the stuff that was originally in <code>V</code>? I expect it to remain in memory but no longer accessible. Does that chunk of memory gets directly marked as free after the swap? i.e., gets somehow deallocated?</p>
<p>Other sources suggest <code>V.clear()</code> and then <code>V.shrink_to_fit()</code>. Is this a better option?</p>

How to properly setup custom handler404 in django? : <p>According to the <a href="https://docs.djangoproject.com/en/dev/topics/http/views/#customizing-error-views" rel="noreferrer">documentation</a> this should be fairly simple: I just need to define <code>handler404</code>. Currently I am doing, in my top <code>urls.py</code>:</p>
<pre><code>urlpatterns = [
...
]
handler404 = 'myapp.views.handle_page_not_found'
</code></pre>
<p>The application is installed. The corresponding view is just (for the time being I just want to redirect to the homepage in case of 404):</p>
<pre><code>def handle_page_not_found(request):
return redirect('homepage')
</code></pre>
<p>But this has no effect: the standard (debug) <code>404</code> page is shown.</p>
<p>The documentation is a bit ambiguous:</p>
<ul>
<li>where should <code>handler404</code> be defined? The documentation says in the <code>URLconf</code> but, where exactly? I have several applications, each with a different <code>urls.py</code>. Can I put it in any of them? In the top <code>URLconf</code>? Why? Where is this documented?</li>
<li>what will be catched by this handler? Will it catch <code>django.http.Http404</code>, <code>django.http.HttpResponseNotFound</code>, <code>django.http.HttpResponse</code> (with <code>status=404</code>)?</li>
</ul>

Purpose of PreAuthenticatedAuthenticationToken in Spring Security? : <p>I am authenticating a User using <a href="http://docs.spring.io/spring-security/site/docs/3.2.2.RELEASE/apidocs/org/springframework/security/authentication/UsernamePasswordAuthenticationToken.html" rel="noreferrer">UsernamePasswordAuthenticationToken</a> in SpringBoot.</p>
<p>I am generating a token using <a href="https://github.com/jwtk/jjwt" rel="noreferrer">JJWT</a> for that User and returning it back.</p>
<p>Now the User uses that token to send any further requests to me. After decrypting the token should I be using <a href="http://docs.spring.io/spring-security/site/docs/3.2.2.RELEASE/apidocs/org/springframework/security/web/authentication/preauth/PreAuthenticatedAuthenticationToken.html" rel="noreferrer">PreAuthenticatedAuthenticationToken</a> and set it to <code>SecurityContextHolder.getContext().setAuthentication()</code>?</p>
<p>What is the purpose of <code>PreAuthenticatedAuthenticationToken</code>?</p>

How to Make a HTML Form Where Files can be Submitted.\ : <p>I'm kind of new to HTML, (not totally) and I was wondering the easiest way to create an HTML form page where users can submit files to. I have tried looking up many pages and tutorials, but they don't seem like what I need. I would want something where someone can submit a file and give it a name and it sends it to a database or something. Does anyone have a webpage where I can find a tutorial (or a video)? </p>
<p>Sorry if this is off-topic in anyway.</p>

Why isn't `std::mem::drop` exactly the same as the closure |_|() in higher-ranked trait bounds? : <p>The implementation of <a href="https://doc.rust-lang.org/std/mem/fn.drop.html" rel="noreferrer"><code>std::mem::drop</code></a> is documented to be the following:</p>
<pre class="lang-rust prettyprint-override"><code>pub fn drop<T>(_x: T) { }
</code></pre>
<p>As such, I would expect the closure <code>|_| ()</code> (colloquially known as the <a href="https://enet4.github.io/rust-tropes/#toilet-closure" rel="noreferrer">toilet closure</a>) to be a potential 1:1 replacement to <code>drop</code>, in both directions. However, the code below shows that <code>drop</code> isn't compatible with a higher ranked trait bound on the function's parameter, whereas the toilet closure is.</p>
<pre class="lang-rust prettyprint-override"><code>fn foo<F, T>(f: F, x: T)
where
for<'a> F: FnOnce(&'a T),
{
dbg!(f(&x));
}
fn main() {
foo(|_| (), "toilet closure"); // this compiles
foo(drop, "drop"); // this does not!
}
</code></pre>
<p>The compiler's error message:</p>
<pre class="lang-none prettyprint-override"><code>error[E0631]: type mismatch in function arguments
--> src/main.rs:10:5
|
1 | fn foo<F, T>(f: F, x: T)
| ---
2 | where
3 | for<'a> F: FnOnce(&'a T),
| ------------- required by this bound in `foo`
...
10 | foo(drop, "drop"); // this does not!
| ^^^
| |
| expected signature of `for<'a> fn(&'a _) -> _`
| found signature of `fn(_) -> _`
error[E0271]: type mismatch resolving `for<'a> <fn(_) {std::mem::drop::<_>} as std::ops::FnOnce<(&'a _,)>>::Output == ()`
--> src/main.rs:10:5
|
1 | fn foo<F, T>(f: F, x: T)
| ---
2 | where
3 | for<'a> F: FnOnce(&'a T),
| ------------- required by this bound in `foo`
...
10 | foo(drop, "drop"); // this does not!
| ^^^ expected bound lifetime parameter 'a, found concrete lifetime
</code></pre>
<p>Considering that <code>drop</code> is supposedly generic with respect to any sized <code>T</code>, it sounds unreasonable that the "more generic" signature <code>fn(_) -> _</code> is not compatible with <code>for<'a> fn (&'a _) -> _</code>. Why is the compiler not admitting the signature of <code>drop</code> here, and what makes it different when the toilet closure is placed in its stead?</p>

What my code is trying to do.
Create a list of playlist titles.
Count how many playlists and add a windows form button for each playlist.
Add playlist title to the button.
When button is selected, match button number to playlist... do stuff
My question is... how would i display " MessageBox.Show(hostList[btn.GetNum1()])" outside of the private void ButtonClick. I cant change it to public without errors. Is my get/set right? Would someone mind placing my messagebox outside private but still have it show on button press please.
If you also have any tips for better practices please share.
I have googled and searched but hit a wall. Any help would be appreciated.

In microservices should i use pub/sub instead RPC to get more loosely couple architecture? : <p>I current using a RPC call to another microservice via TCP and getting the response, but I think I can do it in this way:</p>
<p>whithout make a RPC call, can I use a pub/sub to send to one service, publishing some channel like <em>request_user</em> and subscribed to a channel like <em>object_user_response</em>, and then the other service that is subscribed to this <em>request_user</em>, publish <em>object_user_response</em>.</p>
<p>Like that:</p>
<pre><code>Service A <-- (sub)object_user_response <------ Redis
Service A --> (pub)request_user -------------> Redis
Service B <-- (sub)request_user <--------------- Redis
Service B --> (pub) object_user_response ------> Redis
</code></pre>
<p>On receive a object_user_response, the service A checks if the id of user is the same that the function have requested. </p>
<p>Should I use RPC or Pub/sub for that?
What is the most correct way to send data to a microservice and get response from there in terms of loosely coupled architecture, is using a RPC call or using two pub/sub, on for the request and another for the response? </p>

my program runs fine and i am able copy the object however when i used the copy assignment (=) it still runs fine .why is it not giving error? : this is my code.i didnt overload the (=) operator but still it runs fine in codeblocks.however when i ran this code on c++ shell it compiled succesfully however the output was blank .can somebody please explain me that why is it running fine in codeblocks even though i didnt write the code for the copy assignment .
also another question...
if in line 1 i change the return type to string instead of string& it displays an error (about temporary variable) but if i change the code of line 2 to dummy(dummy& abc : ptr(new string (abc.print())) the program runs fine (despite the return type of line 1 being string)
why is it so?
class dummy{
string *ptr;
public:
dummy(string ab) {ptr=new string; ptr=&ab;}
~dummy (){delete ptr;}
string& print(){return *ptr;} //line1
dummy (dummy& abc){ptr= new string; ptr=&(abc.print());} //line2
dummy (){};
};
int main()
{
dummy x("manzar");
dummy y;
y=x;
cout<<x.print();
cout<<"\n"<<y.print ();
}
i didnt expected it to run fine however it is working fine.it is copying the content from x to y.

Long and wide data – when to use what? : <p>I'm in the process of compiling data from different data sets into one data set for analysis. I'll be doing data exploration, trying different things to find out what regularities may be hidden in the data, so I don't currently have a specific method in mind. Now I'm wondering if I should compile my data into long or wide format.</p>
<p><strong>Which format should I use, and why?</strong></p>
<p>I understand that data can be reshaped from long to wide or vice versa, but the mere existence of this functionality implies that the need to reshape sometimes arises and this need in turn implies that a specific format might be better suited for a certain task. So when do I need which format, and why?</p>
<p>I'm not asking about performance. That has been covered in other questions.</p>

Get DateTime From Internet in C# : <p>I am new in programming and I'm practicing with a project and I need a DateTime for it.

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

StreamReader stream = new StreamReader(response.GetResponseStream());
string html = stream.ReadToEnd();
string time = Regex.Match(html, @"(?<=\btime="")[^""]*").Value;
double milliseconds = Convert.ToInt64(time) / 1000.0;

<pre><code>private void button2_Click(object sender, EventArgs e)
{
var myHttpWebRequest = (HttpWebRequest)WebRequest.Create("http://www.microsoft.com");
var response = myHttpWebRequest.GetResponse();
string todaysDates = response.Headers["date"];
DateTime dateTime = DateTime.ParseExact(todaysDates, "ddd, dd MMM yyyy HH:mm:ss 'GMT'", CultureInfo.InvariantCulture.DateTimeFormat, DateTimeStyles.AssumeUniversal);
textBox2.Text = dateTime.ToString();
response.Close();
}
</code></pre>
<p><strong>So here is the questions :</strong></p>
<p>Which one of this codes you recommend me to use? (I really appreciate it if you give me a better code)</p>
<p>Is that code requires any changes?</p>
<p>Is the code no matter what your location is it still gives you the same time?</p>
<p>Is the code always and on every computer works? (I'v read some comments about port 13 and how the code might not work depends on its status)</p>

An error while finding standart deviation of an image in MATLAB : [enter image description here][1]
[1]: https://i.stack.imgur.com/Gz89O.jpg
Hi,
firstly i want to find standart deviation of this image.
Secondly i want to find standart deviation of all lines in this image.
But, at the first step somethings going wrong and i see this fault.
>> A = imread('C:\Users\PC\Desktop\deneme.jpg');
>> std (A);
Error using var (line 65)
First argument must be single or double.
Error in std (line 38)
y = sqrt(var(varargin{:}));
line 65: error(message('MATLAB:var:integerClass'));
line 38: y = sqrt(var(varargin{:}));
How can i solve this problem and what is the code of finding standart deviation of all lines in this image.
Thank you.

Map in java - getting wrong map size : <p>I am trying to understand how Map interface works in Java. What I am trying to do is: run through the array of strings and for each name in the array <code>name[]</code> put a random <code>grade</code>between 0 to 5. Then map the <code>grade</code>to <code>name[i]</code>. However, the map size gets weird, although I have 10 elements in array, the <code>map.size()</code>is 5 after mapping. Why does the program count the same size several times (see output)? Here is the code and output below:</p>
<pre><code> import java.util.*;
class MapInterfaceExample{
public static void main(String[] args){
int grade = 0;
String[] name = {"Lisa", "Dan", "John", "Adam", "George", "Amanda", "Sarah", "James", "Derek", "Sam"};
Map<Integer,String> map=new HashMap<Integer,String>();
for(int i=0; i<name.length; i++){
grade = (int)(Math.random()*5+1);
map.put(grade, name[i]);
//System.out.println(grade + "\t"+ name[i]);
System.out.println("Size of map "+ map.size());}
}
}
</code></pre>
<p>Output:</p>
<p>Size of map 1</p>
<p>Size of map 2</p>
<p>Size of map 2</p>
<p>Size of map 2</p>
<p>Size of map 2</p>
<p>Size of map 3</p>
<p>Size of map 3</p>
<p>Size of map 4</p>
<p>Size of map 4</p>
<p>Size of map 5</p>

to display date by calculating : how can i dispaly the date to exactly after 2 years depending on the user entered date.....by the way i am using "input type=date" method......can you just provide me ideas of dispalying the exact 2 years after date
example: if a users enters the date in the text box using the calender i need the date to be exactly 2 years after to be displayed in the otheer text box
example 1: if i enter date in the text box (lets just take its as some product manufacture date), i want it to automatically calculate the the entered date and display the 2 years later on date(the expiry date)
by the i am using javascript.......i am happy if i get any ideas based on html, jquery

getting the SUM() of claps and at the same time counting bookmarks in one query : I TRIED A LOT OF SOLUTION THAT LOOKS SIMILAR TO MY PROBLEM BUT NO ONE WORKED FOR ME .
i have 5 tables (USERS, POSTS, BOOKMARKS, CLAPS, COMMENTS)
**USERS** TABLE:
```
+----+-------+----------------+-------------+------------+
| id | name | email | password | register |
+----+-------+----------------+-------------+------------+
| 1 | lofy | [email protected] | 123 | 2019-05-06 |
| 2 | jake | [email protected] | 123 | 2019-06-22 |
| 3 | moly | [email protected] | 123 | 2019-05-15 |
+----+-------+----------------+-------------+------------+
```
**POSTS** TABLE:
```
+----+-------+-------------------+--------------+------------+
| id | title | body | writer_id | date |
+----+-------+-------------------+--------------+------------+
| 1 | lofy | blah blah blah.. | 1 | 2019-05-06 |
| 2 | jake | blah blah blah.. | 2 | 2019-06-22 |
| 3 | moly | blah blah blah.. | 2 | 2019-05-15 |
+----+-------+-------------------+--------------+------------+
```
**BOOKMARKED** TABLE:
```
+---------+-----------+
| user_id | post_id |
+---------+-----------+
| 1 | 1 |
| 2 | 2 |
| 3 | 2 |
+---------+-----------+
```
**CLAPS** TABLE:
```
+---------+-----------+------------+
| user_id | post_id | claps_times|
+---------+-----------+------------+
| 1 | 1 | 5 |
| 2 | 2 | 13 |
| 3 | 2 | 7 |
+---------+-----------+------------+
```
i used this query to get the posts details + the user name and avatar + how many times this post is bookmarked by the users
```SELECT posts.*, users.name, users.avatar ,
count(bookmarks.post_id) as bookmarksCount
FROM posts
LEFT JOIN users ON users.id = posts.owner
LEFT Join bookmarks ON bookmarks.post_id = posts.id
GROUP BY posts.id
;
```
EVERY THING IS GOOD TILL NOW .
**THE PROBLEM:**
i wanted to get the SUM() of the claps for each post so i added 2 more lines to the previous query , this is the query now:
```
SELECT posts.*, users.name, users.avatar ,
count(bookmarks.post_id) as bookmarksCount ,
SUM(claps.claps_count) AS totalClaps
FROM posts
LEFT JOIN users ON users.id = posts.owner
LEFT Join bookmarks ON bookmarks.post_id = posts.id
LEFT JOIN claps ON claps.post_id = posts.id
GROUP BY posts.id
;
```
THE PROBLEM IS THAT THE RESULT OF THE CLAPS OF THE POST.ID "2" IS DOUBLED IT'S 40 INSTEAD OF 20,
ITS LIKE THE JOIN OF THE COUNT() OF THE BOOKMARKS OF THE POST IS CAUSING THE PROBLEM , IN OTHER WORDS IF THE SUM() OF THE CLAPS ARE 10 AND THE POST IS BOOKMARKED 5 TIMES AFTER COUNT() THAN THE RESULT OF THE CLAPS WILL BE 50 INSTEAD OF 5.
I TRYIED TO SUBQUERY THE SUM() OF THE CLAPS BUT I DIDN'T KNOW HOW TO DO IT .
**CAN YOU PLEASE GIVE ME THE SOLUTION IN SUBQUERY WAY WITH A SOME EXPLANATION CAUSE I WILL ADD THE COUNT() OF THE COMMENTS LATER ON AND MAYBE MORE SUBQUEERIES TOO**
**TY IN ADVANCE**

Facebook-passport with JWT : <p>I've been using <strong>Passport</strong> on my server for user authentication.
When a user is signing in locally (using a username and password), the server sends them a <strong>JWT</strong> which is stored in localstorage, and is sent back to server for every api call that requires user authentication.</p>
<p>Now I want to support <strong>Facebook and Google login</strong> as well. Since I began with Passport I thought it would be best to continue with Passport strategies, using <strong>passport-facebook</strong> and <strong>passport-google-oauth</strong>.</p>
<p>I'll refer to Facebook, but both strategies behave the same. They both require redirection to a server route (<strong>'/auth/facebook'</strong> and <strong>'/auth/facebook/callback'</strong> for that matter).
The process is successful to the point of saving users including their facebook\google ids and tokens on the DB.</p>
<p>When the user is created on the server, a JWT is created (without any reliance on the token received from facebook\google). </p>
<pre><code> ... // Passport facebook startegy
var newUser = new User();
newUser.facebook = {};
newUser.facebook.id = profile.id;
newUser.facebook.token = token; // token received from facebook
newUser.facebook.name = profile.displayName;
newUser.save(function(err) {
if (err)
throw err;
// if successful, return the new user
newUser.jwtoken = newUser.generateJwt(); // JWT CREATION!

<p>The problem is that after its creation, <strong>I don't find a proper way to send the JWT to the client</strong>, since I should also redirect to my app.</p>
<pre><code>app.get('/auth/facebook/callback',
passport.authenticate('facebook', {
session: false,
successRedirect : '/',
failureRedirect : '/'
}), (req, res) => {
var token = req.user.jwtoken;
res.json({token: token});
});
</code></pre>
<p>The code above <strong>redirects me to my app main page, but I don't get the token</strong>.
If I remove the successRedirect, <strong>I do get the token, but I'm not redirected to my app</strong>.</p>
<p>Any solution for that? Is my approach wrong? Any suggestions will do. </p>

CanActivate vs. CanActivateChild with component-less routes : <p>The angular2 documentation about <a href="https://angular.io/docs/ts/latest/guide/router.html#!#guards" rel="noreferrer">Route Guards</a> left me unclear about when it is appropriate to use a <code>CanActivate</code> guards vs. a <code>CanActivateChild</code> guard in combination with component-less routes. </p>
<p><strong>TL;DR:</strong> what's the point in having <code>canActivateChild</code> when I can use a component-less routes with <code>canActivate</code> to achieve the same effect?</p>
<p>Long version: </p>
<blockquote>
<p>We can have multiple guards at every level of a routing hierarchy. The
router checks the CanDeactivate and CanActivateChild guards first,
from deepest child route to the top. Then it checks the CanActivate
guards from the top down to the deepest child route.</p>
</blockquote>
<p>I get that <code>CanActivateChild</code> is checked bottom up and <code>CanActivate</code> is checked top down. What doesn't make sense to me is the following example given in the docs: </p>
<pre><code>@NgModule({
imports: [
RouterModule.forChild([
{
path: 'admin',
component: AdminComponent,
canActivate: [AuthGuard],
children: [
{
path: '',
canActivateChild: [AuthGuard],
children: [
{ path: 'crises', component: ManageCrisesComponent },
{ path: 'heroes', component: ManageHeroesComponent },
{ path: '', component: AdminDashboardComponent }
]
}
]
}
])
],
exports: [
RouterModule
]
})
export class AdminRoutingModule {}
</code></pre>
<p>So the <code>admin</code> path has a component-less route: </p>
<blockquote>
<p>Looking at our child route under the AdminComponent, we have a route
with a path and a children property but it's not using a component. We
haven't made a mistake in our configuration, because we can use a
component-less route.</p>
</blockquote>
<p>Why is the code in this case inserting the <code>AuthGuard</code> in the child and in the root component (path <code>admin</code>)? Wouldn't is suffice to guard at the root? </p>
<p>I have created a <a href="http://plnkr.co/edit/B6s8H17q3pGDp2QAqKIU" rel="noreferrer">plunkr</a> based on the sample that removes the <code>canActivateChild: [AuthGuard]</code> and adds a logout button on the <code>AdminDashboard</code>. Sure enough, the <code>canActivate</code> of the parent route still guards, so what's the point in having <code>canActivateChild</code> when I can use component-less routes with <code>canActivate</code>?</p>

How to execute scripts after docker-compose up? : <p>I'm trying to make my dev process easier/maintainable using docker(-compose).
I do not want to use any volumes (if that's possible).
Why does import.sh not get executed after I run 'docker-compose up -d'?</p>
<p>I have the following files:</p>
<pre><code>docker-compose.yml
mysql
---- import.sh
---- db.sql
---- Dockerfile
</code></pre>
<p>in <strong>docker-compose.yml</strong> there is:</p>
<pre><code>version: '2'
services:
database:
image: mysql
build:
context: ./mysql/
dockerfile: Dockerfile
container_name: mysqltest
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: 123456
</code></pre>
<p>in <strong>/mysql/Dockerfile</strong> there is:</p>
<pre><code>ADD import.sh /tmp/import.sh
ADD db.sql /tmp/db.sql
RUN /tmp/import.sh
</code></pre>
<p>in <strong>/mysql/db.sql</strong> there is:</p>
<pre><code>CREATE DATABASE test1;
CREATE DATABASE test2;
CREATE DATABASE test3;
</code></pre>
