You get this error when you wrongly add shared service to "declaration" in your appmodules instead of adding it to "provider".

Resolve issue Immediate, It's related to internal security

We, SnippetBucket.com working for enterprise linux RedHat, found httpd server don't allow proxy to run, neither localhost or 127.0.0.1, nor any other external domain.

As investigate in server log found

[error] (13)Permission denied: proxy: AJP: attempt to connect to
   10.x.x.x:8069 (virtualhost.virtualdomain.com) failed

Audit log found similar port issue

I am posting an answer here, since I had the same error message for a different reason.

This error message can happen, for example, if you are using apache httpd to proxy requests from a source on protocol A to target on protocol B.

Here is the example of my situation:

AH01144: No protocol handler was valid for the URL /sockjs-node/info (scheme 'ws').

In the case above, what was happening was simply the following. I had enabled mod proxy to proxy websocket requests to nodejs based on path /sockjs-node.

The problem is that node does not use the path /sockjs-node for websocket requests exclusively. It also uses this path for hosting REST entrypoints that deliver information about websockets.

In this manner, when the application would try to open http://localhost:7001/sockjs-node/info, apache httpd would be trying to route the rest call from HTTP protocol to to a Webscoket endpoint call. Node did not accept this.

This lead to the exception above.

So be mindful that even if you enable the right modules, if you try to do the wrong forwarding, this will end with apache httpd informing you that the protocol you tried to use on the target server is not valid.

Solution is just simple.

If you are trying to access server using your local IP address and you are getting error saying like Forbidden You don't have permission to access / on this server

Just open your httpd.conf file from (in my case C:/wamp/bin/apache/apache2.2.21/conf/httpd.conf)

Search for

<Directory "D:/wamp/www/"> .... ..... </Directory>

Replace Allow from 127.0.0.1

to

Allow from all

Save changes and restart your server.

Now you can access your server using your IP address

Just remove/comment the following line from your httpd.conf file (etc/httpd/conf)

Require all granted

This is needed till Apache Version 2.2 and is not required from thereon.

All you have to do is to edit the httpd-xampp.conf

from Require local to Require all granted in the LocationMatch tag.

That's it!

I had the same problem, but believe it or not is was a case of case sensitivity.

This on localhost: http://localhost/.../getdata.php?id=3

Did not behave the same as this on the server: http://server/.../getdata.php?id=3

Changing the server url to this (notice the capital D in getData) solved my issue. http://localhost/.../getData.php?id=3

After spend a lot time, trying follow these answers actually after code below it worked for me. Before do it just but be sure that there is no problem in update :)

gem update --system

In Ubuntu I did not found httpd.conf, It may not exit longer now. Edit in apache2.conf file working for me.

cd /etc/apache2
sudo gedit apache2.conf

Here in apache2.conf change

<Directory /var/www/>
     Options Indexes FollowSymLinks
     AllowOverride None
     Require all granted
</Directory>

to

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>  

Ok... I know that there are 1.000.000 answers to this questions already, - but I have spent at least 6 effective hours, figuring this one out; and I have googled it hundreds of times and not found a single post about it. So I figured that I would add the solution to my problem here.

The conclusion

If I commented these two lines out in my .conf-files in the /etc/apache2/[[SERVER-NAME].conf-file:

php_admin_value engine Off
IPCComTimeout 31

I have no idea what they do or how they got there, - but it is in every one of my .conf-files. And if I remove those lines and ensure that there is a symlink in /etc/apache2/sites-enabled/-folder, then it doesn't download the index.php - and every works as it should.

The entire story

I have VirtualMin installed on an Ubuntu 16.04 VPS. I upgraded to PHP version 7.2. Shortly after that, I updated the Ubuntu-version and struck a 'Kernel Offset: Disabled'-error. So I had to go delete the latest Ubuntu-version, - and when my OS booted up again: BOOM! I got the error that his post talks about: For every site on my VPS, it simply downloaded the index.php instead of showing it.

I tried all kinds of stuff:

• Removed PHP7.2 and installed PHP5.6 (I know now, that the PHP-version has nothing to do with it; it's the apache-configuration that needs work).
• Tried enabling and disabling apache modules, on the existing installation, but without luck.
• Then I removed apache completely and installed it again, where-after the problem was still there!
• Tried playing around with the Virutal Server setup in VirtualMin ( Webmin >> Servers >> Apache Webserver ).
• Checked the configuration on a single Virtual-server ( Virtualmin >> System Settings >> Re-Check Configuration )... This step was pretty nice, since it told which module in Apache was missing; where-after I could enable it with a2enmod [MODULE_NAME]. And I found the module name by Googling around. I had to active about 6-8 modules, before I got past that step in the validation - and it took a couple of minutes before the cache ran out, - so doing this was a tedious step.
• And lastly, I figured out above-written conclusion - together with the symlinks, - and then I got it to work. I had to go through it for every site on my VPS, though.

Some times if you have php version conflicts it happens To overcome that please follow the below steps

Step 1 : Yum list installed | grep 'php'

if you have multiple versions of php like php 5.6 and php 7.0 this confilict will happens

Step 2 : yum remove **your php version **

Step 3 : Then restart the apapche /etc/init.d/httpd restart or service apache2 restart

You can change youralias.conf file like this code:

Alias /Quiz/ "h:/MyServer/Quiz/" 
 <Directory "h:/MyServer/Quiz/">
   Options Indexes FollowSymLinks
   AllowOverride all
   <IfDefine APACHE24>
     Require local
   </IfDefine>
   <IfDefine !APACHE24>
    Order Deny,Allow
    Deny from all
    Allow from localhost ::1 127.0.0.1
   </IfDefine>
 </Directory>

To get mod_rewrite to work for me in Apache 2.4, I had to add the "Require all granted" line below.

<Directory /var/www>
   # Required if running apache > 2.4
   Require all granted

   RewriteEngine on 
   RewriteRule ^cachebust-([a-z0-9]+)\/(.*) /$2 [L] 
 </Directory>

supposedly a similar requirement exists for Apache 2.2 as well, if you're using that:

<Directory /var/www>
   # Required if running apache 2.2
   Order allow,deny
   Allow from all

   RewriteEngine on 
   RewriteRule ^cachebust-([a-z0-9]+)\/(.*) /$2 [L] 
 </Directory>

Note that an ErrorDocument 404 directive can sometimes override these things as well, so if it's not working try commenting out your ErrorDocument directive and see if it works. The above example can be used to ensure a site isn't served from cache by including a subfolder in the path, though the files reside at the root of the server.

Try installing mod_ssl using following command:

yum install mod_ssl

and then reload and restart your Apache server using following commands:

systemctl reload httpd.service
systemctl restart httpd.service

This should work for most of the cases.

Click on Wamp icon and open Apache/httpd.conf and search "#LoadModule rewrite_module modules/mod_rewrite.so". Remove # as below and save it

LoadModule rewrite_module modules/mod_rewrite.so

and restart all service.

The first time I struggled with mod_rewrite rules ignoring my traffic, I learned (frustratingly) that I had placed them in the wrong <VirtualHost>, which meant that my traffic would ignore all of them no matter how well-written they were. Make sure this isn't happening to you:

# Change the log location to suit your system. RewriteLog /var/log/apache-rw.log RewriteLogLevel 2

These parameters will activate if you perform a graceful restart of Apache, so you can recycle them in and closely monitor the mod_rewrite behavior. Once your problem is fixed, turn the RewriteLogLevel back down and celebrate.

In 100% of my experience, I've found that the RewriteLog has helped me discover the problem with my rewrite rules. I can't recommend this enough. Good luck in your troubleshooting!

Also, this bookmark is your best friend: http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html#rewritelog

You can loop through all the Animals using foreach and put it into NewAnimals.

As noted by Brad and Nemoden in their answers above, strtotime() is a great function. Personally, I found the standard DateTime Object to be overly complicated for many use cases. I just wanted to add 5 minutes to the current time, for example.

I wrote a function that returns a date as a string with some optional parameters:
1.) time:String | ex: "+5 minutes" (default = current time)
2.) format:String | ex: "Y-m-d H:i:s" (default = "Y-m-d H:i:s O")

Obviously, this is not a fully featured method. Just a quick and simple function for modifying/formatting the current date.

function get_date($time=null, $format='Y-m-d H:i:s O')
{
    if(empty($time))return date($format);
    return date($format, strtotime($time));
}

// Example #1: Return current date in default format
$date = get_date(); 

// Example #2: Add 5 minutes to the current date
$date = get_date("+5 minutes"); 

// Example #3: Subtract 30 days from the current date & format as 'Y-m-d H:i:s'
$date = get_date("-30 days", "Y-m-d H:i:s"); 

We strive for response times of 20 milliseconds, while some complex pages take up to 100 milliseconds. For the most complex pages, we break the page down into smaller pieces, and use the progressive display pattern to load each section. This way, some portions load quickly, even if the page takes 1 to 2 seconds to load, keeping the user engaged while the rest of the page is loading.

First, you should disable selinux, edit file /etc/sysconfig/selinux so it looks like this:

SELINUX=disabled
SELINUXTYPE=targeted

Save file and restart system.

Then you can add the new rule to iptables:

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

and restart iptables with /etc/init.d/iptables restart

If it doesn't work you should check other network settings.

You can use a keyboard shortcut ALT + Break to stop the query execution. However, this may not succeed in all cases.

i hope this will work too, try using"is_null"

<?php 
$web = the_field('website');
if (!is_null($web)) {
?>

....html code here

<?php
} else { 
    echo "Niente";
}
?>

http://php.net/manual/en/function.is-null.php

hope that suits you..

You can create table variable instead of tamp table in procedure A and execute procedure B and insert into temp table by below query.

DECLARE @T TABLE
(
TABLE DEFINITION
)
.
.
.
INSERT INTO @T
EXEC B @MYDATE

and you continue operation.

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

VAR=<<END
abc
END

doesn't work because you are redirecting stdin to something that doesn't care about it, namely the assignment

export A=`cat <<END
sdfsdf
sdfsdf
sdfsfds
END
` ; echo $A

works, but there's a back-tic in there that may stop you from using this. Also, you should really avoid using backticks, it's better to use the command substitution notation $(..).

export A=$(cat <<END
sdfsdf
sdfsdf
sdfsfds
END
) ; echo $A

Do git help gitignore

You will get the help page with following line:

A line starting with # serves as a comment.

You can give your input textboxes class names, like so:

<input type="text" value="2" name="pages_title[1]" class="pages_title">
<input type="text" value="1" name="pages_title[2]" class="pages_title">

and iterate like so:

$('input.pages_title').each(function() {
    alert($(this).val()); 
});

If it is test code you want to time, then you can use the time attribute:

@Test(timeout = 1000)  
public void shouldTakeASecondOrLess()
{
}

If it is production code, there is no simple mechanism, and which solution you use depends upon whether you can alter the code to be timed or not.

If you can change the code being timed, then a simple approach is is to have your timed code remember it's start time, and periodically the current time against this. E.g.

long startTime = System.currentTimeMillis();
// .. do stuff ..
long elapsed = System.currentTimeMillis()-startTime;
if (elapsed>timeout)
   throw new RuntimeException("tiomeout");

If the code itself cannot check for timeout, you can execute the code on another thread, and wait for completion, or timeout.

    Callable<ResultType> run = new Callable<ResultType>()
    {
        @Override
        public ResultType call() throws Exception
        {
            // your code to be timed
        }
    };

    RunnableFuture future = new FutureTask(run);
    ExecutorService service = Executors.newSingleThreadExecutor();
    service.execute(future);
    ResultType result = null;
    try
    {
        result = future.get(1, TimeUnit.SECONDS);    // wait 1 second
    }
    catch (TimeoutException ex)
    {
        // timed out. Try to stop the code if possible.
        future.cancel(true);
    }
    service.shutdown();
}

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

I had the same problem but it occured in all my projects, I tried Invalidate Cache / Restart but even it doesn´t solved the problem.

At the end I realized that in my Gradle Settings, Offline Work was enabled.

Go to Build, Execution, Deployment > Gradle in Gradle Settings unchecked Offline Work.

It solved the the problem downloading some configuration files for my Android Studio.

ES6 (template literal) helper functions:

function rgba(r, g, b, a=1){
    return `rgba(${r}, ${g}, ${b}, ${a})`
}
function rgb(r, g, b){
    return `rgb(${r}, ${g}, ${b})`
}

Here's a simple, yet powerful example, using the apache class HierarchicalINIConfiguration:

HierarchicalINIConfiguration iniConfObj = new HierarchicalINIConfiguration(iniFile); 

// Get Section names in ini file     
Set setOfSections = iniConfObj.getSections();
Iterator sectionNames = setOfSections.iterator();

while(sectionNames.hasNext()){

 String sectionName = sectionNames.next().toString();

 SubnodeConfiguration sObj = iniObj.getSection(sectionName);
 Iterator it1 =   sObj.getKeys();

    while (it1.hasNext()) {
    // Get element
    Object key = it1.next();
    System.out.print("Key " + key.toString() +  " Value " +  
                     sObj.getString(key.toString()) + "\n");
}

Commons Configuration has a number of runtime dependencies. At a minimum, commons-lang and commons-logging are required. Depending on what you're doing with it, you may require additional libraries (see previous link for details).

I had this error and found it was due to the presence an 'Import' XML tag inside the .csproj.user file. Once I removed it, Visual Studio could open the project again.

I think currently the application-context.xml file is into src/main/resources AND the social.properties file is into src/main/java... so when you package (mvn package) or when you run tomcat (mvn tomcat:run) your social.properties disappeared (I know you said when you checked into the .war the files are here... but your exception says the opposite).

The solution is simply to put all your configuration files (application-context.xml and social.properties) into src/main/resources to follow the maven standard structure.

cat < File > | awk '{if(NR > 6) print $0}'

Apart from the similarities i.e. Task.Run() being a shorthand for Task.Factory.StartNew(), there is a minute difference between their behaviour in case of sync and async delegates.

Suppose there are following two methods:

public async Task<int> GetIntAsync()
{
    return Task.FromResult(1);
}

public int GetInt()
{
    return 1;
}

Now consider the following code.

var sync1 = Task.Run(() => GetInt());
var sync2 = Task.Factory.StartNew(() => GetInt());

Here both sync1 and sync2 are of type Task<int>

However, difference comes in case of async methods.

var async1 = Task.Run(() => GetIntAsync());
var async2 = Task.Factory.StartNew(() => GetIntAsync());

In this scenario, async1 is of type Task<int>, however async2 is of type Task<Task<int>>

In my Notepad++ 7.2.2, the Preferences section it's a bit different.

The option is located at: Settings / Preferences / Language / Replace by space as in the Screenshot.

Another solution would be,you can get the object itself as value if you are not mentioning it's id as value: Note: [value] and [ngValue] both works here.

<select (change)="your_method(values[$event.target.selectedIndex])">
  <option *ngFor="let v of values" [value]="v" >  
    {{v.name}}
  </option>
</select>

In ts:

your_method(v:any){
  //access values here as needed. 
  // v.id or v.name
}

Note: If you are using reactive form and you want to catch selected value on form Submit, you should use [ngValue] directive instead of [value] in above scanerio

Example:

  <select (change)="your_method(values[$event.target.selectedIndex])" formControlName="form_control_name">
      <option *ngFor="let v of values" [ngValue]="v" >  
        {{v.name}}
      </option>
    </select>

In ts:

form_submit_method(){
        let v : any = this.form_group_name.value.form_control_name;  
    }

you should open like this

        Excel.Application xlApp ;
        Excel.Workbook xlWorkBook ;
        Excel.Worksheet xlWorkSheet ;
        object misValue = System.Reflection.Missing.Value;

        xlApp = new Excel.ApplicationClass();
        xlWorkBook = xlApp.Workbooks.Open("csharp.net-informations.xls", 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
        xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

Taking the answer from @jack-allan I modified the function slightly to allow ES6 default properties such as:

function( a, b = 1, c ){};

to still return [ 'a', 'b' ]

/**
 * Get the keys of the paramaters of a function.
 *
 * @param {function} method  Function to get parameter keys for
 * @return {array}
 */
var STRIP_COMMENTS = /((\/\/.*$)|(\/\*[\s\S]*?\*\/))/mg;
var ARGUMENT_NAMES = /(?:^|,)\s*([^\s,=]+)/g;
function getFunctionParameters ( func ) {
    var fnStr = func.toString().replace(STRIP_COMMENTS, '');
    var argsList = fnStr.slice(fnStr.indexOf('(')+1, fnStr.indexOf(')'));
    var result = argsList.match( ARGUMENT_NAMES );

    if(result === null) {
        return [];
    }
    else {
        var stripped = [];
        for ( var i = 0; i < result.length; i++  ) {
            stripped.push( result[i].replace(/[\s,]/g, '') );
        }
        return stripped;
    }
}

Including its "big result", this paper describes a couple of variants of in-place merge sort (PDF):

In-place sorting with fewer moves

Jyrki Katajainen, Tomi A. Pasanen

It is shown that an array of n elements can be sorted using O(1) extra space, O(n log n / log log n) element moves, and n log₂n + O(n log log n) comparisons. This is the first in-place sorting algorithm requiring o(n log n) moves in the worst case while guaranteeing O(n log n) comparisons, but due to the constant factors involved the algorithm is predominantly of theoretical interest.

I think this is relevant too. I have a printout of it lying around, passed on to me by a colleague, but I haven't read it. It seems to cover basic theory, but I'm not familiar enough with the topic to judge how comprehensively:

http://comjnl.oxfordjournals.org/cgi/content/abstract/38/8/681

Optimal Stable Merging

Antonios Symvonis

This paper shows how to stably merge two sequences A and B of sizes m and n, m = n, respectively, with O(m+n) assignments, O(mlog(n/m+1)) comparisons and using only a constant amount of additional space. This result matches all known lower bounds...

Pretty Late answer though. But This has worked for me , and could be useful.

While Using Spring Security ans mockMvc, all you need to is use @WithMockUser annotation like others are mentioned.

Spring security also provides another annotation called @WithAnonymousUser for testing unauthenticated requests. However you should be careful here. You would be expecting 401, but I got 403 Forbidden Error by default. In actual scenarios, when you are running actual service, It is redirected and you end up getting the correct 401 response code.Use this annotation for anonymous requests.

You may also think of ommitting the annotaions and simply keep it unauthorized. But this usually raises the correct exceptions(like AuthenticationException), but you will get correct status code if it is handled correctly(If you are using custom handler). I used to get 500 for this. So look for the exceptions raised in the debugger, and check if it is handled rightly and returns the correct status code.

Doing the expicit casting to the "int" solves the problem in my case. I had the same issue. So:

int count = (int)[myColors count];

The easiest solution is to convert your categorical variable to a factor prior to the subsetting. Bottomline is that you need a factor variable with exact the same levels in all your subsets.

library(ggplot2)
dataset <- data.frame(category = rep(LETTERS[1:5], 100), 
    x = rnorm(500, mean = rep(1:5, 100)), y = rnorm(500, mean = rep(1:5, 100)))
dataset$fCategory <- factor(dataset$category)
subdata <- subset(dataset, category %in% c("A", "D", "E"))

With a character variable

ggplot(dataset, aes(x = x, y = y, colour = category)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = category)) + geom_point()

With a factor variable

ggplot(dataset, aes(x = x, y = y, colour = fCategory)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = fCategory)) + geom_point()

private void setClock() {

    Timeline clock = new Timeline(new KeyFrame(Duration.ZERO, e -> {
        Calendar cal = Calendar.getInstance();
        int second = cal.get(Calendar.SECOND);
        int minute = cal.get(Calendar.MINUTE);
        int  hour = cal.get(Calendar.HOUR_OF_DAY);
        eski_minut = minute;
        if(second < 10){

            time_label.setText(hour + ":" + (minute) + ":0" + second);

        }else if (minute < 10){
            time_label.setText(hour + ":0" + (minute) + ":0" + second);

        }
        else {
        time_label.setText(hour + ":" + (minute) + ":" + second);}
    }),
            new KeyFrame(Duration.seconds(1))
    );
    clock.setCycleCount(Animation.INDEFINITE);
    clock.play();
}

The MessageBox does produce a DialogResults

DialogResult r = MessageBox.Show("Some question here");

You can also specify the buttons easily enough. More documentation can be found at http://msdn.microsoft.com/en-us/library/ba2a6d06.aspx

$result = mysql_query("SELECT option_value FROM wp_10_options WHERE option_name='homepage'");
$row = mysql_fetch_assoc($result);

I have crawled through a lot of blog posts including a few Stack Overflow pots, and I already had everything in place what these posts suggested (see below) when I got this error.

1. My app pool is running under ApplicationPoolIdentity
2. Load user Profile was set to True in Process Model section
3. IIS AppPool\DefaultAppPool has full permissions on temp ASP.NET files folder

Finally I found some clues in the below mentioned blog post. It looks like there is heap contention with the same user account. So I changed the app pool identity to LocalSystem, for the app which is failing with this error - and my app started working fine.

See blog post C# compiler or Visual Basic .Net compilers fail with error code -1073741502 when generating assemblies for your ASP.net site.

Note: LocalSystem account will not have much permissions. In my case my application does not need any special permissions. So I was fine. If your application needs special permissions try configuring a custom account.

In your Request class (that extends Request), override the getParams() method. You would do the same for headers, just override getHeaders().

If you look at PostWithBody class in TestRequest.java in Volley tests, you'll find an example. It goes something like this

public class LoginRequest extends Request<String> {

    // ... other methods go here

    private Map<String, String> mParams;

    public LoginRequest(String param1, String param2, Listener<String> listener, ErrorListener errorListener) {
        super(Method.POST, "http://test.url", errorListener);
        mListener = listener;
        mParams = new HashMap<String, String>();
        mParams.put("paramOne", param1);
        mParams.put("paramTwo", param2);

    }

    @Override
    public Map<String, String> getParams() {
        return mParams;
    }
}

Evan Charlton was kind enough to make a quick example project to show us how to use volley. https://github.com/evancharlton/folly/

The second way you showed uses an extension method to execute the delegate method for each of the elements in the list.

This way, you have another delegate (=method) call.

Additionally, there is the possibility to iterate the list with a for loop.

This solution without timeouts! Real force redraw! For Android and iOS.

var forceRedraw = function(element){
  var disp = element.style.display;
  element.style.display = 'none';
  var trick = element.offsetHeight;
  element.style.display = disp;
};

Basically "ANSI" refers to the legacy codepage on Windows. See also an article by Raymond Chen on this topic:

The source of this comes from the fact that the Windows code page 1252 was originally based on an ANSI draft, which became ISO Standard 8859-1.

The first 127 characters are identical to ASCII in most code pages, the upper characters vary, though.

However, ANSI does not automatically mean CP1252 or Latin 1.

All confusion notwithstanding you should simply avoid such issues nowadays and use Unicode.

Try using {} instead of ():

${"file".$i} = file($filelist[$i]);

I encountered the same problem in the code and What I did is I found out all the changes I have made from the last correct compilation. And I have observed one function declaration was without ";" and also it was passing a value and I have declared it to pass nothing "void". this method will surely solve the problem for many.

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

As explained here, The “Iterable” was introduced to be able to use in the foreach loop. A class implementing the Iterable interface can be iterated over.

Iterator is class that manages iteration over an Iterable. It maintains a state of where we are in the current iteration, and knows what the next element is and how to get it.

For Bootstrap 4 I find the following very handy because:

• the column on the right takes exactly the space it needs and will pull right
• while the left col always gets the maximum amount of space!.

It is the combination of col and col-auto which does the magic. So you don't have to define a col width (like col-2,...)

<div class="row">
    <div class="col">Left</div>
    <div class="col-auto">Right</div>
</div>

Ideal for aligning words, icons, buttons,... to the right.

An example to have this responsive on small devices:

<div class="row">
    <div class="col">Left</div>
    <div class="col-12 col-sm-auto">Right (Left on small)</div>
</div>

As everyone has said, a shared resource - specifically something that cannot handle concurrent access.

One specific example that I have seen, is a Lucene Search Index Writer.

With sdk, you can't write to the root of internal storage. This cause your error.

Edit :

Based on your code, to use internal storage with sdk:

final File dir = new File(context.getFilesDir() + "/nfs/guille/groce/users/nicholsk/workspace3/SQLTest");
dir.mkdirs(); //create folders where write files
final File file = new File(dir, "BlockForTest.txt");

I got similar error while using in-app-purchase in android. My mistake is I used wrong purchase id while instantiating the purchases.

public static final String PRODUCT_ID_ASTRO_Match = "android.test.product";//wrong id not in play store dev console

Replaced it with:

public static final String PRODUCT_ID_ASTRO_Match = "android.test.purchased";

and it worked.

.catch(error => { throw error}) is a no-op. It results in unhandled rejection in route handler.

As explained in this answer, Express doesn't support promises, all rejections should be handled manually:

router.get("/emailfetch", authCheck, async (req, res, next) => {
  try {
  //listing messages in users mailbox 
    let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
    emailFetch = emailFetch.data
    res.send(emailFetch)
  } catch (err) {
    next(err);
  }
})

On Windows there is an experimental build that does this, as described on the mailing list, Filter by local process name

By default, tnsnames.ora is located in the $ORACLE_HOME/network/admin directory on UNIX operating systems and in the ORACLE_HOME\network\admin directory on Windows operating systems. tnsnames.ora can also be stored the following locations:

The directory specified by the TNS_ADMIN environment variable (or registry value)

On UNIX operating systems, the global configuration directory. For example, on the Solaris Operating System, this directory is /var/opt/oracle

If you have multiple ORACLE_HOMES, be aware of which one you are using, as the location of the tnsnames.ora file can vary from one ORACLE_HOME to the next.

For the person who mentioned the TWO_TASK environment variable, that is used to set a default database service name to connect to (which could be a database on another server). The service name you set TWO_TASK to is then looked up in the tnsnames.ora file when you connect.

It looks like the answer is at least 12 million if you have a beefy server, your server software is optimized for it, you have enough clients. If you test from one client to one server, the number of port numbers on the client will be one of the obvious resource limits (Each TCP connection is defined by the unique combination of IP and port number at the source and destination).

(You need to run multiple clients as otherwise you hit the 64K limit on port numbers first)

When it comes down to it, this is a classic example of the witticism that "the difference between theory and practise is much larger in practise than in theory" - in practise achieving the higher numbers seems to be a cycle of a. propose specific configuration/architecture/code changes, b. test it till you hit a limit, c. Have I finished? If not then d. work out what was the limiting factor, e. go back to step a (rinse and repeat).

Here is an example with 2 million TCP connections onto a beefy box (128GB RAM and 40 cores) running Phoenix http://www.phoenixframework.org/blog/the-road-to-2-million-websocket-connections - they ended up needing 50 or so reasonably significant servers just to provide the client load (their initial smaller clients maxed out to early, eg "maxed our 4core/15gb box @ 450k clients").

Here is another reference for go this time at 10 million: http://goroutines.com/10m.

This appears to be java based and 12 million connections: https://mrotaru.wordpress.com/2013/06/20/12-million-concurrent-connections-with-migratorydata-websocket-server/

The other advantage of using curl is that you also can keep the HTTP way of sending parameters to your script if you need to, by using $_GET, $_POST etc like this:

*/5 * * * * curl --request GET 'http://exemple.com/path/check.php?param1=1&param2=2'

In Swift5 and Xcode 10.2

//Save
UserDefaults.standard.set(true, forKey: "Key1") //Bool
UserDefaults.standard.set(1, forKey: "Key2")  //Integer
UserDefaults.standard.set("This is my string", forKey: "Key3") //String
UserDefaults.standard.synchronize()

//Retrive
UserDefaults.standard.bool(forKey: "Key1")
UserDefaults.standard.integer(forKey: "Key2")
UserDefaults.standard.string(forKey: "Key3")

//Remove
UserDefaults.standard.removeObject(forKey: "Key3")

Note: Save text data(means String, Array, Dictionary etc.) in UserDefaults. Don't save images in UserDefaults, it's not recommended(Save images in local directory).

If you`re not using jQuery then please make sure:

var json_upload = "json_name=" + JSON.stringify({name:"John Rambo", time:"2pm"});
var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
xmlhttp.open("POST", "/file.php");
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.send(json_upload);

And for the php receiving end:

 $_POST['json_name'] 

For those (like me) who was looking for the same solution in Kotlin and were pointed to Java only - how to trim in Kotlin:

fun main(args: Array<String>) {
    // array definition
    val array = arrayListOf<String>(" String", "Tom Selleck "," Fish ")
    println(array) // print original -> [ String, Tom Selleck ,  Fish ]

    // remove leading and trailing spaces, result is arrayList
    val sol1 = array.map { it.trim() }
    println("sol1 = $sol1") // -> sol1 = [String, Tom Selleck, Fish]

    // remove leading and trailing spaces, result is String
    val sol2 = array.joinToString { it.trim() }
    println("sol2 = $sol2") // -> sol2 = String, Tom Selleck, Fish
}

You could try using the system stored procedure sp_help_job. This returns information on the job, its steps, schedules and servers. For example

EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'

SQL Books Online should contain lots of information about the records it returns.

For returning information on multiple jobs, you could try querying the following system tables which hold the various bits of information on the job

• msdb.dbo.SysJobs
• msdb.dbo.SysJobSteps
• msdb.dbo.SysJobSchedules
• msdb.dbo.SysJobServers
• msdb.dbo.SysJobHistory

Their names are fairly self-explanatory (apart from SysJobServers which hold information on when the job last run and the outcome).

Again, information on the fields can be found at MSDN. For example, check out the page for SysJobs

I've tried everything here, but for me it was a completely different issue: I had to remove from my *.d.ts any import statements:

import { SomeModuleType } from '3rd-party-module';

After removing the error went away...

Clarification: When we declare a module in a *.d.ts file, it's automatically picked up by the Typescript compiler as an ambient module (the one you don't need to import explicitly). Once we specify the import ... from ..., the file now becomes a normal (ES6) module, and hence won't be picked up automatically. Hence if you still want it to behave as an ambient module, use a different import style like so:

type MyType: import('3rd-party-module').SomeModuleType;

A rather separable way of doing this is to use

import tensorflow as tf
from keras import backend as K

num_cores = 4

if GPU:
    num_GPU = 1
    num_CPU = 1
if CPU:
    num_CPU = 1
    num_GPU = 0

config = tf.ConfigProto(intra_op_parallelism_threads=num_cores,
                        inter_op_parallelism_threads=num_cores, 
                        allow_soft_placement=True,
                        device_count = {'CPU' : num_CPU,
                                        'GPU' : num_GPU}
                       )

session = tf.Session(config=config)
K.set_session(session)

Here, with booleans GPU and CPU, we indicate whether we would like to run our code with the GPU or CPU by rigidly defining the number of GPUs and CPUs the Tensorflow session is allowed to access. The variables num_GPU and num_CPU define this value. num_cores then sets the number of CPU cores available for usage via intra_op_parallelism_threads and inter_op_parallelism_threads.

The intra_op_parallelism_threads variable dictates the number of threads a parallel operation in a single node in the computation graph is allowed to use (intra). While the inter_ops_parallelism_threads variable defines the number of threads accessible for parallel operations across the nodes of the computation graph (inter).

allow_soft_placement allows for operations to be run on the CPU if any of the following criterion are met:

1. there is no GPU implementation for the operation

2. there are no GPU devices known or registered

3. there is a need to co-locate with other inputs from the CPU

All of this is executed in the constructor of my class before any other operations, and is completely separable from any model or other code I use.

Note: This requires tensorflow-gpu and cuda/cudnn to be installed because the option is given to use a GPU.

Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.

If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

To do something after certain div load from function .load(). I think this exactly what you need:

  $('#divIDer').load(document.URL +  ' #divIDer',function() {

       // call here what you want .....


       //example
       $('#mydata').show();
  });

I've gotten same problem. The servers logs showed:

DEBUG: <-- origin: null

I've investigated that and it occurred that this is not populated when I've been calling from file from local drive. When I've copied file to the server and used it from server - the request worked perfectly fine

• Ensure debug mode is on - either add APP_DEBUG=true to .env file or set an environment variable

• Log files are in storage/logs folder. laravel.log is the default filename. If there is a permission issue with the log folder, Laravel just halts. So if your endpoint generally works - permissions are not an issue.

• In case your calls don't even reach Laravel or aren't caused by code issues - check web server's log files (check your Apache/nginx config files to see the paths).

• If you use PHP-FPM, check its log files as well (you can see the path to log file in PHP-FPM pool config).

Just wondering why you are using 2 directives?

It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.

Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).

It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.

Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

dirty CSS only fix to stay scrolled up every time the anchor is used (not useful if you still want to use anchors for scroll-jumps, very useful for deeplinking):

   margin-top: -9999px; //higher thin page height

OK, let's separate the question of the characters that:

1. aren't valid at all in any XML document.
2. need to be escaped.

The answer provided by @dolmen in "What are invalid characters in XML" is still valid but needs to be updated with the XML 1.1 specification.

1. Invalid characters

The characters described here are all the characters that are allowed to be inserted in an XML document.

1.1. In XML 1.0

• Reference: see XML recommendation 1.0, §2.2 Characters

The global list of allowed characters is:

[2] Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */

Basically, the control characters and characters out of the Unicode ranges are not allowed. This means also that calling for example the character entity  is forbidden.

1.2. In XML 1.1

• Reference: see XML recommendation 1.1, §2.2 Characters, and 1.3 Rationale and list of changes for XML 1.1

The global list of allowed characters is:

[2] Char ::= [#x1-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */

[2a] RestrictedChar ::= [#x1-#x8] | [#xB-#xC] | [#xE-#x1F] | [#x7F-#x84] | [#x86-#x9F]

This revision of the XML recommendation has extended the allowed characters so control characters are allowed, and takes into account a new revision of the Unicode standard, but these ones are still not allowed : NUL (x00), xFFFE, xFFFF...

However, the use of control characters and undefined Unicode char is discouraged.

It can also be noticed that all parsers do not always take this into account and XML documents with control characters may be rejected.

2. Characters that need to be escaped (to obtain a well-formed document):

The < must be escaped with a < entity, since it is assumed to be the beginning of a tag.

The & must be escaped with a & entity, since it is assumed to be the beginning a entity reference

The > should be escaped with > entity. It is not mandatory -- it depends on the context -- but it is strongly advised to escape it.

The ' should be escaped with a ' entity -- mandatory in attributes defined within single quotes but it is strongly advised to always escape it.

The " should be escaped with a " entity -- mandatory in attributes defined within double quotes but it is strongly advised to always escape it.

There are two types of WITH clauses:

Here is the FizzBuzz in SQL form, using a WITH common table expression (CTE).

;WITH mil AS (
 SELECT TOP 1000000 ROW_NUMBER() OVER ( ORDER BY c.column_id ) [n]
 FROM master.sys.all_columns as c
 CROSS JOIN master.sys.all_columns as c2
)                
 SELECT CASE WHEN n  % 3 = 0 THEN
             CASE WHEN n  % 5 = 0 THEN 'FizzBuzz' ELSE 'Fizz' END
        WHEN n % 5 = 0 THEN 'Buzz'
        ELSE CAST(n AS char(6))
     END + CHAR(13)
 FROM mil

Here is a select statement also using a WITH clause

SELECT * FROM orders WITH (NOLOCK) where order_id = 123

Check out this plunkr.

When you're binding to variables, you need to use the brackets. Also, you use the hashtag when you want to get references to elements in your html, not for declaring variables inside of templates like that.

<md-button-toggle *ngFor="let indicador of indicadores; let first = first;" [value]="indicador.id" [checked]="first"> 
...

Edit: Thanks to Christopher Moore: Angular exposes the following local variables:

• index
• first
• last
• even
• odd

If you have a string like this: '123456' and you want a list of integers like this: [1,2,3,4,5,6], use this:

>>>s = '123456'    
>>>list1 = [int(i) for i in list(s)]
>>>print(list1)

[1,2,3,4,5,6]

or if you want a list of strings like this: ['1','2','3','4','5','6'], use this:

>>>s = '123456'    
>>>list1 = list(s)
>>>print(list1)

['1','2','3','4','5','6']

This guy had the magic wand we were looking for, guys.

To quote his answer:

just add "position:fixed" and it will keep it in view even if you scroll down. see it at http://jsfiddle.net/XEUbc/1/

#mydiv {
    position:fixed;
    top: 50%;
    left: 50%;
    width:30em;
    height:18em;
    margin-top: -9em; /*set to a negative number 1/2 of your height*/
    margin-left: -15em; /*set to a negative number 1/2 of your width*/
    border: 1px solid #ccc;
    background-color: #f3f3f3;
}

If you don't need a plot per say, and you're simply interested in adding color to represent the values in a table format, you can use the style.background_gradient() method of the pandas data frame. This method colorizes the HTML table that is displayed when viewing pandas data frames in e.g. the JupyterLab Notebook and the result is similar to using "conditional formatting" in spreadsheet software:

import numpy as np 
import pandas as pd


index= ['aaa', 'bbb', 'ccc', 'ddd', 'eee']
cols = ['A', 'B', 'C', 'D']
df = pd.DataFrame(abs(np.random.randn(5, 4)), index=index, columns=cols)
df.style.background_gradient(cmap='Blues')

For detailed usage, please see the more elaborate answer I provided on the same topic previously and the styling section of the pandas documentation.

This turned out to NOT be a bower problem, though it showed up for me with bower.

It seems to be a node-which problem. If a file is in the path, but has the setuid/setgid bit set, which will not find it.

Here is a files with the s bit set: (unix 'which' will find it with no problems).

ls -al /usr/local/bin -rwxrwsr-- 110 root nmt 5535636 Jul 17 2012 git

Here is a node-which attempt:

> which.sync('git')
Error: not found: git

I change the permissions (chomd 755 git). Now node-which can find it.

> which.sync('git')
'/usr/local/bin/git'

Hope this helps.

All this peace of code put into *.bat file and run all at once:

My code for creating user in oracle. crate_drop_user.sql file

create file import.bat and put this lines in it:

SQLPLUS SYSTEM/systempassword@ORA_alias @"crate_drop_user.SQL"
IMP SYSTEM/systempassword@ORA_alias FILE=user.DMP FROMUSER=user TOUSER=user GRANTS=Y log =user.log

Be carefull if you will import from one user to another. For example if you have user named user1 and you will import to user2 you may lost all grants , so you have to recreate it.

Good luck, Ivan

The only solution for such warnings is to include stdlib.h in the program.

This are the steps :

1. Download and install latest version of pclink for PC from here.
2. Make sure PCLink is running in Foreground on Asus Zenfone 5 and in settings on rightmost topmost corner click on USB icon and then check the MTP checkbox.
3. Click connect on PCLink on PC.
4. If Asus USB Driver for Zenfone 5 is properly installed on your PC.You will see 'Asus Android Device' in your Device Manager otherwise install Asus USB Driver for Zenfone 5 from here then try again
5. Now you will be able to see your device online in Android Studio and screen of your device on PCLink software on your PC.

I haven't tried for eclipse but it might work for that also.

I like simbu's approach, but I ain't comfortable to use first-child or last-child. Instead I only modify the content of a repeating list-comma class.

.list-comma + .list-comma::before {
    content: ', ';
}

<span class="list-comma" ng-repeat="destination in destinations">
    {{destination.name}}
</span>

TouchableOpacity extents TouchableWithoutFeedback, so you can just use the disabled property :

<TouchableOpacity disabled={true}>
  <Text>I'm disabled</Text>
</TouchableOpacity>

React Native TouchableWithoutFeedback #disabled documentation

The new Pressable API has a disabled option too :

<Pressable disable={true}>
  {({ pressed }) => (
    <Text>I'm disabled</Text>
  )}
</Pressable>

If wants to open virtual environment on Windows then just remember one thing on giving path use backwards slash not forward.

This is right:

D:\xampp\htdocs\htmldemo\python-virtual-environment>env\Scripts\activate

This is wrong:

D:\xampp\htdocs\htmldemo\python-virtual-environment>env/Scripts/activate

If you want to move files around and keep the csproj files up to date, the easiest way is to use a Visual Studio plugin like AnkhSVN. That will automatically commit both the move action (as an delete + add with history, because that's how Subversion works) and a change in the .csproj

For me it was simply a matter of restarting the docker daemon..

The copy constructor given by @Stephen C is the way to go when you have a Set you created (or when you know where it comes from). When it comes from a Map.entrySet(), it will depend on the Map implementation you're using:

findbugs says

The entrySet() method is allowed to return a view of the underlying Map in which a single Entry object is reused and returned during the iteration. As of Java 1.6, both IdentityHashMap and EnumMap did so. When iterating through such a Map, the Entry value is only valid until you advance to the next iteration. If, for example, you try to pass such an entrySet to an addAll method, things will go badly wrong.

As addAll() is called by the copy constructor, you might find yourself with a Set of only one Entry: the last one.

Not all Map implementations do that though, so if you know your implementation is safe in that regard, the copy constructor definitely is the way to go. Otherwise, you'd have to create new Entry objects yourself:

Set<K,V> copy = new HashSet<K,V>(map.size());
for (Entry<K,V> e : map.entrySet())
    copy.add(new java.util.AbstractMap.SimpleEntry<K,V>(e));

Edit: Unlike tests I performed on Java 7 and Java 6u45 (thanks to Stephen C), the findbugs comment does not seem appropriate anymore. It might have been the case on earlier versions of Java 6 (before u45) but I don't have any to test.

If the column type is DateTime in SQL then it will store a time where you pass one or not.

It'd be better to save the date properly:

model.ReturnDate = DateTime.Now;

and then format it when you need to display it:

@Html.Label(Model.ReturnDate.ToShortDateString())

Or if you're using EditorFor:

@Html.EditorFor(model => model.ReturnDate.ToShortDateString())

or

@Html.EditorFor(model => model.ReturnDate.ToString("MM/dd/yyyy"))

To add a property to your model add this code:

public string ReturnDateForDisplay
{
    get
    {
       return this.ReturnDate.ToString("d");
    }
}

Then in your PartialView:

@Html.EditorFor(model => model.ReturnDateForDisplay)

EDIT:

I just want to clarify for this answer that by my saying 'If you're using EditorFor', that means you need to have an EditorFor template for the type of value you're trying to represent.

Editor templates are a cool way of managing repetitive controls in MVC:

http://coding-in.net/asp-net-mvc-3-how-to-use-editortemplates/

You can use them for naive types like String as I've done above; but they're especially great for letting you template a set of input fields for a more complicated data type.

Use jquery cookie plugin, the link as working today: https://github.com/js-cookie/js-cookie

If you are running tomcat from eclipse (probably problem exists with another IDEs), it could have a different configuration- not based on files .

The solution is to edit tomcat users file, as you wrote, and then start tomcat from command prompt with

{tomcat-directory}/bin/startup

If you're using react native and react-native-firebase, make sure you link up the Google-Services.plist file (https://github.com/invertase/react-native-firebase/issues/313#issuecomment-320435560)

So you are asking for ArgMin or ArgMax. C# doesn't have a built-in API for those.

I've been looking for a clean and efficient (O(n) in time) way to do this. And I think I found one:

The general form of this pattern is:

var min = data.Select(x => (key(x), x)).Min().Item2;
                            ^           ^       ^
              the sorting key           |       take the associated original item
                                Min by key(.)

Specially, using the example in original question:

For C# 7.0 and above that supports value tuple:

var youngest = people.Select(p => (p.DateOfBirth, p)).Min().Item2;

For C# version before 7.0, anonymous type can be used instead:

var youngest = people.Select(p => new {age = p.DateOfBirth, ppl = p}).Min().ppl;

They work because both value tuple and anonymous type have sensible default comparers: for (x1, y1) and (x2, y2), it first compares x1 vs x2, then y1 vs y2. That's why the built-in .Min can be used on those types.

And since both anonymous type and value tuple are value types, they should be both very efficient.

NOTE

In my above ArgMin implementations I assumed DateOfBirth to take type DateTime for simplicity and clarity. The original question asks to exclude those entries with null DateOfBirth field:

Null DateOfBirth values are set to DateTime.MaxValue in order to rule them out of the Min consideration (assuming at least one has a specified DOB).

It can be achieved with a pre-filtering

people.Where(p => p.DateOfBirth.HasValue)

So it's immaterial to the question of implementing ArgMin or ArgMax.

NOTE 2

The above approach has a caveat that when there are two instances that have the same min value, then the Min() implementation will try to compare the instances as a tie-breaker. However, if the class of the instances does not implement IComparable, then a runtime error will be thrown:

At least one object must implement IComparable

Luckily, this can still be fixed rather cleanly. The idea is to associate a distanct "ID" with each entry that serves as the unambiguous tie-breaker. We can use an incremental ID for each entry. Still using the people age as example:

var youngest = Enumerable.Range(0, int.MaxValue)
               .Zip(people, (idx, ppl) => (ppl.DateOfBirth, idx, ppl)).Min().Item3;

From python >= 3.5 onward, you can use **, glob.iglob(path/**, recursive=True) and it seems the most pythonic solution, i.e.:

import glob, os

for filename in glob.iglob('/pardadox-music/**', recursive=True):
    if os.path.isfile(filename): # filter dirs
        print(filename)

Output:

/pardadox-music/modules/her1.mod
/pardadox-music/modules/her2.mod
...

Notes:
1 - glob.iglob

glob.iglob(pathname, recursive=False)

Return an iterator which yields the same values as glob() without actually storing them all simultaneously.

2 - If recursive is True, the pattern '**' will match any files and zero or more directories and subdirectories.

3 - If the directory contains files starting with . they won’t be matched by default. For example, consider a directory containing card.gif and .card.gif:

>>> import glob
>>> glob.glob('*.gif') ['card.gif'] 
>>> glob.glob('.c*')['.card.gif']

4 - You can also use rglob(pattern), which is the same as calling glob() with **/ added in front of the given relative pattern.

pd.read_excel(file_name) 

sometimes this code gives an error for xlsx files as: XLRDError:Excel xlsx file; not supported

instead , you can use openpyxl engine to read excel file.

df_samples = pd.read_excel(r'filename.xlsx', engine='openpyxl')

It worked for me

Assuming m is a string, you can use endswith:

if m.endswith('.mp3'):
...
elif m.endswith('.flac'):
...

To be case-insensitive, and to eliminate a potentially large else-if chain:

m.lower().endswith(('.png', '.jpg', '.jpeg'))

You would just use '%' as your wildcard like this:

GRANT ALL ON *.* to root@'192.168.1.%' IDENTIFIED BY 'your-root-password';

For a completely stateless utility class in Java, I suggest the class be declared public and final, and have a private constructor to prevent instantiation. The final keyword prevents sub-classing and can improve efficiency at runtime.

The class should contain all static methods and should not be declared abstract (as that would imply the class is not concrete and has to be implemented in some way).

The class should be given a name that corresponds to its set of provided utilities (or "Util" if the class is to provide a wide range of uncategorized utilities).

The class should not contain a nested class unless the nested class is to be a utility class as well (though this practice is potentially complex and hurts readability).

Methods in the class should have appropriate names.

Methods only used by the class itself should be private.

The class should not have any non-final/non-static class fields.

The class can also be statically imported by other classes to improve code readability (this depends on the complexity of the project however).

Example:

public final class ExampleUtilities {
    // Example Utility method
    public static int foo(int i, int j) {
        int val;

        //Do stuff

        return val;
    }

    // Example Utility method overloaded
    public static float foo(float i, float j) {
        float val;

        //Do stuff

        return val;
    }

    // Example Utility method calling private method
    public static long bar(int p) {
        return hid(p) * hid(p);
    }

    // Example private method
    private static long hid(int i) {
        return i * 2 + 1;
    }
}

Perhaps most importantly of all, the documentation for each method should be precise and descriptive. Chances are methods from this class will be used very often and its good to have high quality documentation to complement the code.

Solution to this is

Specific Solution to the example problem:-

Try [A-Z]*123$ will match 123, AAA123, ASDFRRF123. In case you need at least a character before 123 use [A-Z]+123$.

General Solution to the question (How to match "any character" in the regular expression):

1. If you are looking for anything including whitespace you can try [\w|\W]{min_char_to_match,}.
2. If you are trying to match anything except whitespace you can try [\S]{min_char_to_match,}.

Syntax to change column name in MySql:

alter table table_name change old_column_name new_column_name data_type(size);

Example:

alter table test change LowSal Low_Sal integer(4);

For Scroll down in Selenium use below code:

Till the bottom drop down, scroll till the height of the page. Use the below javascript code that would work fine in both, JavaScript and React.

JavascriptExecutor jse = (JavascriptExecutor) driver; // (driver is your browser webdriver object) 
jse.executeScript("window.scrollBy(0,document.body.scrollHeight || document.documentElement.scrollHeight)", "");

You should define the style on the td element like so:

<html>
<head>
    <style type="text/css">
        .bb
        {
            border-bottom: solid 1px black;
        }
    </style>
</head>
<body>
    <table>
        <tr>
            <td>
                Test 1
            </td>
        </tr>
        <tr>
            <td class="bb">
                Test 2
            </td>
        </tr>
    </table>
</body>
</html>

You don't need to declare the variable. Ajax success function automatically takes up to 3 parameters: Function( Object data, String textStatus, jqXHR jqXHR )

In my Jenkins instance (version 1.548) the configuration file is at:

/var/lib/jenkins/jobs/-the-project-name-/config.xml

Owned by jenkins user and jenkins group with 644 permissions. Copying the file to and from here should work. I haven't tried changing it directly but have backed-up the config from this spot in case the project needs to be setup again.

You need to set the Format of the DateTimePicker to Custom and then assign the CustomFormat.

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    DateTimePicker1.Format = DateTimePickerFormat.Custom
    DateTimePicker1.CustomFormat = "dd/MM/yyyy"
End Sub

Beautiful Soup handles entity conversion. In Beautiful Soup 3, you'll need to specify the convertEntities argument to the BeautifulSoup constructor (see the 'Entity Conversion' section of the archived docs). In Beautiful Soup 4, entities get decoded automatically.

Beautiful Soup 3

>>> from BeautifulSoup import BeautifulSoup
>>> BeautifulSoup("<p>&pound;682m</p>", 
...               convertEntities=BeautifulSoup.HTML_ENTITIES)
<p>£682m</p>

Beautiful Soup 4

>>> from bs4 import BeautifulSoup
>>> BeautifulSoup("<p>&pound;682m</p>")
<html><body><p>£682m</p></body></html>

If you have several versions of Python installed, /usr/bin/env will ensure the interpreter used is the first one on your environment's $PATH. The alternative would be to hardcode something like #!/usr/bin/python; that's ok, but less flexible.

In Unix, an executable file that's meant to be interpreted can indicate what interpreter to use by having a #! at the start of the first line, followed by the interpreter (and any flags it may need).

If you're talking about other platforms, of course, this rule does not apply (but that "shebang line" does no harm, and will help if you ever copy that script to a platform with a Unix base, such as Linux, Mac, etc).

I looked around for an answer to this and the best way I found was to use Flex and inline styling on different components.

For example, to make two paper components divide my full screen in 2 vertical components (in ration of 1:4), the following code works fine.

const styles = {
  div:{
    display: 'flex',
    flexDirection: 'row wrap',
    padding: 20,
    width: '100%'
  },
  paperLeft:{
    flex: 1,
    height: '100%',
    margin: 10,
    textAlign: 'center',
    padding: 10
  },
  paperRight:{
    height: 600,
    flex: 4,
    margin: 10,
    textAlign: 'center',
  }
};

class ExampleComponent extends React.Component {
  render() {
    return (
      <div>
        <div style={styles.div}>
          <Paper zDepth={3} style={styles.paperLeft}>
            <h4>First Vertical component</h4>
          </Paper>
          <Paper zDepth={3} style={styles.paperRight}>
              <h4>Second Vertical component</h4>
          </Paper>
        </div>
      </div>
    )
  }
}

Now, with some more calculations, you can easily divide your components on a page.

Streams Java 8

Along with forEach method that accepts a lambda expression we have also got stream APIs, in Java 8.

Iterate over entries (Using forEach and Streams):

sample.forEach((k,v) -> System.out.println(k + "=" + v)); 
sample.entrySet().stream().forEachOrdered((entry) -> {
            Object currentKey = entry.getKey();
            Object currentValue = entry.getValue();
            System.out.println(currentKey + "=" + currentValue);
        });
sample.entrySet().parallelStream().forEach((entry) -> {
            Object currentKey = entry.getKey();
            Object currentValue = entry.getValue();
            System.out.println(currentKey + "=" + currentValue);
        });

The advantage with streams is they can be parallelized easily and can be useful when we have multiple CPUs at disposal. We simply need to use parallelStream() in place of stream() above. With parallel streams it makes more sense to use forEach as forEachOrdered would make no difference in performance. If we want to iterate over keys we can use sample.keySet() and for values sample.values().

Why forEachOrdered and not forEach with streams ?

Streams also provide forEach method but the behaviour of forEach is explicitly nondeterministic where as the forEachOrdered performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. So forEach does not guarantee that the order would be kept. Also check this for more.

package com.example;

public class MyClass  {
    static int mycount=0;
    static Thread t;
    static Thread t2;
    public static void main(String[] arg)
    {
        t2=new Thread(new Runnable() {
            @Override
            public void run() {
                System.out.print(mycount++ + " even \n");
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                if(mycount>25)
                    System.exit(0);
                run();
            }
        });
        t=new Thread(new Runnable() {
            @Override
            public void run() {
                System.out.print(mycount++ + " odd \n");
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                if(mycount>26)
                    System.exit(0);
                run();
            }
        });
        t.start();
        t2.start();
    }
}

You need to append form itself to body too:

$form = $("<form></form>");
$form.append('<input type="button" value="button">');
$('body').append($form);

You can also use the FileReader class :

    var reader = new FileReader();
    reader.onload = function (e) {
        var data = this.result;
    }
    reader.readAsDataURL( file );

Put the default value in single quote and it will work as intended. An example of migration:

$table->increments('id');
            $table->string('name');
            $table->string('url');
            $table->string('country');
            $table->tinyInteger('status')->default('1');
            $table->timestamps();

EDIT : in your case ->default('100.0');

Assuming that you want to group the data before you generate the key with the sequence, it sounds like you want something like

INSERT INTO HISTORICAL_CAR_STATS (
    HISTORICAL_CAR_STATS_ID, 
    YEAR,
    MONTH, 
    MAKE,
    MODEL,
    REGION,
    AVG_MSRP,
    CNT) 
SELECT MY_SEQ.nextval,
       year,
       month,
       make,
       model,
       region,
       avg_msrp,
       cnt
  FROM (SELECT '2010' year,
               '12' month,
               'ALL' make,
               'ALL' model,
               REGION,
               sum(AVG_MSRP*COUNT)/sum(COUNT) avg_msrp,
               sum(cnt) cnt
          FROM HISTORICAL_CAR_STATS
         WHERE YEAR = '2010' 
           AND MONTH = '12'
           AND MAKE != 'ALL' 
         GROUP BY REGION)

None of these worked for me (aggravated by the Thawte bug as well). Eventually I got it fixed with Self-signed SSL acceptance on Android and Custom SSL handling stopped working on Android 2.2 FroYo

just edit wp_user table with your phpmyadmin, and choose MD5 on Function field then input your new password, save it (go button).

In my case, my maven variable environment was M2_HOME, so I've changed to MAVEN_HOME and worked.

If you are only looking to point to a different location for you identity file, the you can modify your ~/.ssh/config file with the following entry:

IdentityFile ~/.foo/identity

man ssh_config to find other config options.

I'm using this to only enable a button if a listview item is selected (ie not null):

<Style TargetType="{x:Type Button}">
    <Setter Property="IsEnabled" Value="True"/>
    <Style.Triggers>
        <DataTrigger Binding="{Binding ElementName=lvMyList, Path=SelectedItem}" Value="{x:Null}">
            <Setter Property="IsEnabled" Value="False"/>
        </DataTrigger>
    </Style.Triggers>
</Style>

Bootstrap modal exposes events. Listen for the the shown event like this

$('#my-modal').on('shown', function(){
  // code here
});

The code for specific digits after decimals is:

var roundedString = String(format: "%.2f", currentRatio)

Here the %.2f tells the swift to make this number rounded to 2 decimal places.

First of all, it's actually not accurate to say that

x % 2 == x & 1

Simple counterexample: x = -1. In many languages, including Java, -1 % 2 == -1. That is, % is not necessarily the traditional mathematical definition of modulo. Java calls it the "remainder operator", for example.

With regards to bitwise optimization, only modulo powers of two can "easily" be done in bitwise arithmetics. Generally speaking, only modulo powers of base b can "easily" be done with base b representation of numbers.

In base 10, for example, for non-negative N, N mod 10^k is just taking the least significant k digits.

Alex, Gary:

As requested, here is my comment posted as an answer:

var rt = ($(window).width() - ($whatever.offset().left + $whatever.outerWidth()));

Thanks for letting me know.

In pseudo code that can be expressed as:

The right offset is:

The window's width MINUS
( The element's left offset PLUS the element's outer width )

It appears there's a simple answer. Consider this:

var Child = React.createClass({
  render: function() {
    <a onClick={this.props.onClick.bind(null, this)}>Click me</a>
  }
});

var Parent = React.createClass({
  onClick: function(component, event) {
    component.props // #=> {Object...}
  },
  render: function() {
    <Child onClick={this.onClick} />
  }
});

The key is calling bind(null, this) on the this.props.onClick event, passed from the parent. Now, the onClick function accepts arguments component, AND event. I think that's the best of all worlds.

UPDATE: 9/1/2015

This was a bad idea: letting child implementation details leak in to the parent was never a good path. See Sebastien Lorber's answer.

From the Android docs (March 2016):

Before attempting to use this type of acceleration, you should first determine if your development system’s CPU supports one of the following virtualization extensions technologies:

• Intel Virtualization Technology (VT, VT-x, vmx) extensions
• AMD Virtualization (AMD-V, SVM) extensions (only supported for Linux)

The specifications from the manufacturer of your CPU should indicate if it supports virtualization extensions. If your CPU does not support one of these virtualization technologies, then you cannot use virtual machine acceleration.

Note: Virtualization extensions are typically enabled through your computer's BIOS and are frequently turned off by default. Check the documentation for your system's motherboard to find out how to enable virtualization extensions.

Most people talk about Genymotion being faster, and I have never heard anyone say it's slower. I definitely think it's faster, and it will be worth the ~20 minutes it will take to set up just to try it.

The first thing is to make a comparison of functions of SHA and opt for the safest algorithm that supports your programming language (PHP).

Then you can chew the official documentation to implement the hash() function that receives as argument the hashing algorithm you have chosen and the raw password.

sha256 => 64 bits sha384 => 96 bits sha512 => 128 bits

The more secure the hashing algorithm is, the higher the cost in terms of hashing and time to recover the original value from the server side.

$hashedPassword = hash('sha256', $password);

Although the accepted answer works fine, since v0.21.0rc1 it gives a warning

Because any client can set the user-agent to what they want, looking for 'Googlebot', 'bingbot' etc is only half the job.

The 2nd part is verifying the client's IP. In the old days this required maintaining IP lists. All the lists you find online are outdated. The top search engines officially support verification through DNS, as explained by Google https://support.google.com/webmasters/answer/80553 and Bing http://www.bing.com/webmaster/help/how-to-verify-bingbot-3905dc26

At first perform a reverse DNS lookup of the client IP. For Google this brings a host name under googlebot.com, for Bing it's under search.msn.com. Then, because someone could set such a reverse DNS on his IP, you need to verify with a forward DNS lookup on that hostname. If the resulting IP is the same as the one of the site's visitor, you're sure it's a crawler from that search engine.

I've written a library in Java that performs these checks for you. Feel free to port it to PHP. It's on GitHub: https://github.com/optimaize/webcrawler-verifier

All of the above answers ignore the fact that you mention you have no window or navigator :-)

Then I openede developer console in IE11

and thats where it says

Object not found and needs to be re-evaluated.

and navigator, window, console, none of them exist and need to be re-evaluated. I've had that in emulation. just close and open the console a few times.

var d = new Date();
var v = new Date();
v.setMinutes(d.getMinutes()+20);

Here's one I made. It doesn't use a second variable, which I like.

        Points = Len(Cells(1, i)) * 1.2
        If Round(Points) >= Points Then
            Points = Round(Points)
        Else: Points = Round(Points) + 1
        End If

I'd like to offer yet another solution. It's similar to the already proposed ones as it uses HTML-code in a JLabel, and registers a MouseListener on it, but it also displays a HandCursor when you move the mouse over the link, so the look&feel is just like what most users would expect. If browsing is not supported by the platform, no blue, underlined HTML-link is created that could mislead the user. Instead, the link is just presented as plain text. This could be combined with the SwingLink class proposed by @dimo414.

if your project maven based, you can also try updating your project maven config by selecting project. Right click project> Maven>Update Project option. it will update your project config.

In JQuery you can call

$("form:first").trigger("submit")

Don't know if that is much better. I think form.submit(); is pretty universal.

If you just need to pause a loop or script, and you're happy to press Enter instead of any key, then read on its own will do the job.

do_stuff
read
do_more_stuff

It's not end-user friendly, but may be enough in cases where you're writing a quick script for yourself, and you need to pause it to do something manually in the background.

Assaf's response of

sounds flippant, but actually it's pertinant.

Only today we had an issue where a record failed to be inserted into our Rate table, because one of the columns (GrossRate) is set to Decimal (11,4), and our Product department just got a contract for rooms in some amazing resort in Bora Bora, that sell for several million Pacific Francs per night... something that was never anticpated when the database schema was designed 10 years ago.

Both tmux and GNU Screen work under cygwin. They can be installed from the cygwin installer. Just search for their name there and you probably will get to the latest version (at least for tmux).

textcolor function is no longer supported in the latest compilers.

This the simplest way to change text color in Code Blocks. You can use system function.

To change Text Color :

#include<stdio.h> 
#include<stdlib.h> //as system function is in the standard library

int main()        
        {
          system("color 1"); //here 1 represents the text color
          printf("This is dummy program for text color");
          return 0;
        }

If you want to change both the text color & console color you just need to add another color code in system function

To change Text Color & Console Color :

system("color 41"); //here 4 represents the console color and 1 represents the text color

N.B: Don't use spaces between color code like these

system("color 4 1");

Though if you do it Code Block will show all the color codes. You can use this tricks to know all supported color codes.

Or even shorter, with only standard modern Javascript:

var first_link = document.getElementsByTagName('a')[0];
first_link.dispatchEvent(new MouseEvent('click'));

The new MouseEvent constructor takes a required event type name, then an optional object (at least in Chrome). So you could, for example, set some properties of the event:

first_link.dispatchEvent(new MouseEvent('click', {bubbles: true, cancelable: true}));

right click on app-->select

New-->Select Folder-->then click on Assets Folder

LIKE and the equality operator have different purposes, they don't do the same thing:
= is much faster, whereas LIKE can interpret wildcards. Use = wherever you can and LIKE wherever you must.

SELECT * FROM user WHERE login LIKE 'Test%';

Sample matches:

TestUser1
TestUser2
TestU
Test

Use

serialize( )

var str = $("form").serialize();

Serialize a form to a query string, that could be sent to a server in an Ajax request.

I have recently used google mobile vision in both ios and android. I highly recommend to use Google Barcode Scan. It is pretty responsive with any orientation and processing time is pretty fast. It is called Google Mobile Vision.

The Barcode Scanner API detects barcodes in real time in any orientation. You can also detect and parse several barcodes in different formats at the same time.

https://developers.google.com/vision/

https://codelabs.developers.google.com/codelabs/bar-codes/#0

My suspicion is the problem lies in your route definition.

You defined the route as a GET request but the form is probably sending a POST request. Change your route definition to match the form's request method.

Route::post('/validate', [MemberController::class, 'validateCredentials']);

It's generally better practice to use named routes (helps to scale if the controller method/class changes).

Route::post('/validate', [MemberController::class, 'validateCredentials'])
    ->name('member.validateCredentials');

In the view, use the validation route as the form's action.

<form action="{{ route('member.validateCredentials') }}" method="POST">
  @csrf
...
</form>

In bash you can use -v inside the [[ ]] builtin:

#! /bin/bash -u

if [[ ! -v SOMEVAR ]]; then
    SOMEVAR='hello'
fi

echo $SOMEVAR

It is because Bootstrap's DEFAULT CSS for <hr /> is ::

hr {
    margin-top: 20px;
    margin-bottom: 20px;
    border: 0;
    border-top: 1px solid #eeeeee;
}

it creates 40px gap between those two lines

so if you want to change any particular <hr /> margin style in your page you may try something like this ::

<hr style="margin-bottom:5px !important; margin-top:5px !important; " />

if you want to change appearance/other styles of any particular <hr /> in your page like color and border type or thickness the you may try something like :

<hr style="border-top: 1px dotted #000000 !important; " />

for all <hr /> in your page

<style>
   hr {
       border-top: 1px dotted #000000 !important;
       margin-bottom:5px !important; 
       margin-top:5px !important;
   }
</style>

Use splice if you already know the index of the element you want to delete.

Grep works if you are searching.

If you need to do a lot of these, you will get much better performance if you keep your array in sorted order, since you can then do binary search to find the necessary index.

If it makes sense in your context, you may want to consider using a "magic value" for deleted records, rather then deleting them, to save on data movement -- set deleted elements to undef, for example. Naturally, this has its own issues (if you need to know the number of "live" elements, you need to keep track of it separately, etc), but may be worth the trouble depending on your application.

Edit Actually now that I take a second look -- don't use the grep code above. It would be more efficient to find the index of the element you want to delete, then use splice to delete it (the code you have accumulates all the non-matching results..)

my $index = 0;
$index++ until $arr[$index] eq 'foo';
splice(@arr, $index, 1);

That will delete the first occurrence. Deleting all occurrences is very similar, except you will want to get all indexes in one pass:

my @del_indexes = grep { $arr[$_] eq 'foo' } 0..$#arr;

The rest is left as an excercise for the reader -- remember that the array changes as you splice it!

Edit2 John Siracusa correctly pointed out I had a bug in my example.. fixed, sorry about that.

It actually tells you what's wrong, but you ignored it because you didn't check the error returned from json.Marshal.

json: unsupported type: map[int]main.Foo

JSON spec doesn't support anything except strings for object keys, while javascript won't be fussy about it, it's still illegal.

You have two options:

1 Use map[string]Foo and convert the index to string (using fmt.Sprint for example):

datas := make(map[string]Foo, N)

for i := 0; i < 10; i++ {
    datas[fmt.Sprint(i)] = Foo{Number: 1, Title: "test"}
}
j, err := json.Marshal(datas)
fmt.Println(string(j), err)

2 Simply just use a slice (javascript array):

datas2 := make([]Foo, N)
for i := 0; i < 10; i++ {
    datas2[i] = Foo{Number: 1, Title: "test"}
}
j, err = json.Marshal(datas2)
fmt.Println(string(j), err)

In Python you can access the contents of other files like as if they
are some kind of a library, compared to other languages like java or any oop base languages , This is really cool ;

This makes accessing the contents of the file or import it to to process it or to do anything with it ; And that is the Main reason why Python is highly preferred Language for Data Science and Machine Learning etc. ;

And this is the picture of project structure

Where I am accessing variables from .env file where the API links and Secret keys reside .

General Structure:

from <File-Name> import *

I know this is an old question, but since php7.0 you can use the null coalescing operator (another resource).

It similar to the ternary operator, but will behave like isset on the lefthand operand instead of just using its boolean value.

$slide = $_GET["id"] ?? 'fallback';

So if $_GET["id"] is set, it returns the value. If not, it returns the fallback. I found this very helpful for $_POST, $_GET, or any passed parameters, etc

$slide = $_GET["id"] ?? '';

if (trim($slide) == 'link1') ...

Don't put the environment configuration in catalina.bat/catalina.sh. Instead you should create a new file in CATALINA_BASE\bin\setenv.bat to keep your customizations separate of tomcat installation.

Cloud Computing is a large group of interconnected computers.The data are hidden form the user. Grid computing is more than one computers interconnected to resolve the problem.grid computing is worked in cloud computing.

Try

 $(document).on('change','#multiid',function(){
    alert('Change Happened');
});

As your select-box is generated from the code, so you have to use event delegation, where in place of $(document) you can have closest parent element.

Or

$(document.body).on('change','#multiid',function(){
    alert('Change Happened');
});

Update:

Second one works fine, there is another change of selector to make it work.

$('#addbasket').on('change','#multiid',function(){
    alert('Change Happened');
});

Ideally we should use $("#addbasket") as it's the closest parent element [As i have mentioned above].

From http://docs.python.org/tutorial/datastructures.html:

"The keys() method of a dictionary object returns a list of all the keys used in the dictionary, in arbitrary order (if you want it sorted, just apply the sorted() function to it)."

The $.getJSON() method is shorthand that does not let you specify advanced options like that. To do that, you need to use the full $.ajax() method.

Notice in the documentation at http://api.jquery.com/jQuery.getJSON/:

This is a shorthand Ajax function, which is equivalent to:

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

So just use $.ajax() and provide all the extra parameters you need.

We are doing the same thing. To support only TLS 1.2 and no SSL protocols, you can do this:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

SecurityProtocolType.Tls is only TLS 1.0, not all TLS versions.

As a side: If you want to check that your site does not allow SSL connections, you can do so here (I don't think this will be affected by the above setting, we had to edit the registry to force IIS to use TLS for incoming connections): https://www.ssllabs.com/ssltest/index.html

To disable SSL 2.0 and 3.0 in IIS, see this page: https://www.sslshopper.com/article-how-to-disable-ssl-2.0-in-iis-7.html

First, it's always worth noting that git reset --hard is a potentially dangerous command, since it throws away all your uncommitted changes. For safety, you should always check that the output of git status is clean (that is, empty) before using it.

Initially you say the following:

So I know that Git tracks changes I make to my application, and it holds on to them until I commit the changes, but here's where I'm hung up:

That's incorrect. Git only records the state of the files when you stage them (with git add) or when you create a commit. Once you've created a commit which has your project files in a particular state, they're very safe, but until then Git's not really "tracking changes" to your files. (for example, even if you do git add to stage a new version of the file, that overwrites the previously staged version of that file in the staging area.)

In your question you then go on to ask the following:

When I want to revert to a previous commit I use: git reset --hard HEAD And git returns: HEAD is now at 820f417 micro

How do I then revert the files on my hard drive back to that previous commit?

If you do git reset --hard <SOME-COMMIT> then Git will:

• Make your current branch (typically master) back to point at <SOME-COMMIT>.
• Then make the files in your working tree and the index ("staging area") the same as the versions committed in <SOME-COMMIT>.

HEAD points to your current branch (or current commit), so all that git reset --hard HEAD will do is to throw away any uncommitted changes you have.

So, suppose the good commit that you want to go back to is f414f31. (You can find that via git log or any history browser.) You then have a few different options depending on exactly what you want to do:

• Change your current branch to point to the older commit instead. You could do that with git reset --hard f414f31. However, this is rewriting the history of your branch, so you should avoid it if you've shared this branch with anyone. Also, the commits you did after f414f31 will no longer be in the history of your master branch.

• Create a new commit that represents exactly the same state of the project as f414f31, but just adds that on to the history, so you don't lose any history. You can do that using the steps suggested in this answer - something like:

  git reset --hard f414f31
  git reset --soft HEAD@{1}
  git commit -m "Reverting to the state of the project at f414f31"
  

I wrote some test code to check JQueryUI drag/drop. The example shows how to drag an element from a container and drop it to another container.

JQuery codes-

$(document).ready(function() {

$('.box-item').draggable({
    cursor: 'move',
    helper: "clone"
});

$("#container1").droppable({
  drop: function(event, ui) {
    var itemid = $(event.originalEvent.toElement).attr("itemid");
    $('.box-item').each(function() {
      if ($(this).attr("itemid") === itemid) {
        $(this).appendTo("#container1");
      }
    });
  }
});

$("#container2").droppable({
  drop: function(event, ui) {
    var itemid = $(event.originalEvent.toElement).attr("itemid");
    $('.box-item').each(function() {
      if ($(this).attr("itemid") === itemid) {
        $(this).appendTo("#container2");
      }
    });
  }
});

});

CSS-

.box-container {
    height: 200px;
}

.box-item {
    width: 100%;
    z-index: 1000
}

Check the plunker JQuery Drag Drop

You should use a callback parameter:

function Typer(callback)
{
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];
    var interval = setInterval(function() {
        if(i == srcText.length - 1) {
            clearInterval(interval);
            callback();
            return;
        }
        i++;
        result += srcText[i].replace("\n", "<br />");
        $("#message").html(result);
    },
    100);
    return true;


}

function playBGM () {
    alert("Play BGM function");
    $('#bgm').get(0).play();
}

Typer(function () {
    playBGM();
});

// or one-liner: Typer(playBGM);

So, you pass a function as parameter (callback) that will be called in that if before return.

Also, this is a good article about callbacks.

JSFIDDLE

Option 1

If one doesn't know the sheets names

# Read all sheets in your File
df = pd.read_excel('FILENAME.xlsm', sheet_name=None)
    
# Prints all the sheets name in an ordered dictionary
print(df.keys())

Then, depending on the sheet one wants to read, one can pass each of them to a specific dataframe, such as

sheet1_df = pd.read_excel('FILENAME.xlsm', sheet_name=SHEET1NAME)
sheet2_df = pd.read_excel('FILENAME.xlsm', sheet_name=SHEET2NAME)

Option 2

If the name is not relevant and all one cares about is the position of the sheet. Let's say one wants only the first sheet,

# Read all sheets in your File
df = pd.read_excel('FILENAME.xlsm', sheet_name=None)

sheet1 = list(df.keys())[0]

Then, depending on the sheet name, one can pass each it to a specific dataframe, such as

sheet1_df = pd.read_excel('FILENAME.xlsm', sheet_name=SHEET1NAME)

This should help clear up any questions you may have: C# literals

Here is a table from the linked content:

I strongly recommend BOUML which:

• is extremely fast (fastest UML tool ever created, check out benchmarks),
• has rock solid PHP import and export support (also supports C++, Java, Python)
• is multiplatform (Linux, Windows, other OSes),
• is full featured, impressively intensively developed (look at development history, it's hard to believe that such fast progress is possible).
• supports plugins, has modular architecture (this allows user contributions, looks like BOUML community is forming up)

Step 1: Add new column with integer or numeric as per your requirement

Step 2: Populate data from varchar column to numeric column

Step 3: drop varchar column

Step 4: change new numeric column name as per old varchar column

It can be changed in the $CATALINA_BASE/conf/server.xml in the <Host />. See the Tomcat documentation, specifically the section in regards to the Host container:

Tomcat 6 Configuration

Tomcat 7 Configuration

The default is webapps relative to the $CATALINA_BASE. An absolute pathname can be used.

Hope that helps.

try ppretty:

from ppretty import ppretty


class Animal(object):
    def __init__(self):
        self.legs = 2
        self.name = 'Dog'
        self.color= 'Spotted'
        self.smell= 'Alot'
        self.age  = 10
        self.kids = 0


print ppretty(Animal(), seq_length=10)

Output:

__main__.Animal(age = 10, color = 'Spotted', kids = 0, legs = 2, name = 'Dog', smell = 'Alot')

if you call pyplot as plt

frameon=False is to remove the border around the legend

and '' is passing the information that no variable should be in the legend

import matplotlib.pyplot as plt
plt.legend('',frameon=False)

It would help if you showed the code you are using for the simple test program. Put directly into the interpreter this seems to work.

>>> def pyth_test (x1, x2):
...     print x1 + x2
... 
>>> pyth_test(1, 2)
3

I've had some good luck with using multiple, space-separated dataTypes (jQuery 1.5+). As in:

$.ajax({
    type: 'POST',
    url: 'Jqueryoperation.aspx?Operation=DeleteRow',
    contentType: 'application/json; charset=utf-8',
    data: json,
    dataType: 'text json',
    cache: false,
    success: AjaxSucceeded,
    error: AjaxFailed
});

You can also use "shouldReceiveTouch" method of UIGestureRecognizer

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:     (UITouch *)touch {
     UIView *view = touch.view; 
     NSLog(@"%d", view.tag); 
}    

Dont forget to set delegate of your gesture recognizer.

You could write a simple jQuery plugin to do this. The plugin would look like:

(function($) {
    $.fn.expandcollapse = function() {
        return this.each(function() {
            obj = $(this);
            switch (obj.css("display")) {
                case "block":
                    displayValue = "none";
                    break;

                case "none":
                default:
                    displayValue = "block";
            }

            obj.css("display", displayValue);
        });
    };
} (jQuery));

Then wire the plugin up to the click event for the anchor tag:

$(document).ready(function() {
    $("#mylink").click(function() {
        $("div").expandcollapse();
    });
});

Providing that you set the initial 'display' attributes for each div to be 'block' and 'none' respectively, they should switch to being shown/hidden when the link is clicked.

If I understand correctly, you want the List<T> version of new T[size], without the overhead of adding values to it.

If you are not afraid the implementation of List<T> will change dramatically in the future (and in this case I believe the probability is close to 0), you can use reflection:

    public static List<T> NewOfSize<T>(int size) {
        var list = new List<T>(size);
        var sizeField = list.GetType().GetField("_size",BindingFlags.Instance|BindingFlags.NonPublic);
        sizeField.SetValue(list, size);
        return list;
    }

Note that this takes into account the default functionality of the underlying array to prefill with the default value of the item type. All int arrays will have values of 0 and all reference type arrays will have values of null. Also note that for a list of reference types, only the space for the pointer to each item is created.

If you, for some reason, decide on not using reflection, I would have liked to offer an option of AddRange with a generator method, but underneath List<T> just calls Insert a zillion times, which doesn't serve.

I would also like to point out that the Array class has a static method called ResizeArray, if you want to go the other way around and start from Array.

To end, I really hate when I ask a question and everybody points out that it's the wrong question. Maybe it is, and thanks for the info, but I would still like an answer, because you have no idea why I am asking it. That being said, if you want to create a framework that has an optimal use of resources, List<T> is a pretty inefficient class for anything than holding and adding stuff to the end of a collection.

I solve it by close safari inspector. Refer to my post. I also found sound sometimes when I run my app for testing, then I open safari with auto inspector on, after this, I do some action in my app then this issue triggered.

Try with this solution: http://phppot.com/php/sorting-mysql-row-order-using-jquery/ where new order is saved in some HMTL element. Then you submit the form with this data to some PHP script, and iterate trough it with for loop.

Note: I had to add another db field of type INT(11) which is updated(timestamp'ed) on each iteration - it serves for script to know which row is recenty updated, or else you end up with scrambled results.

Given say...

std::string x = "hello";

Getting a `char *` or `const char*` from a `string`

How to get a character pointer that's valid while x remains in scope and isn't modified further

C++11 simplifies things; the following all give access to the same internal string buffer:

const char* p_c_str = x.c_str();
const char* p_data  = x.data();
char* p_writable_data = x.data(); // for non-const x from C++17 
const char* p_x0    = &x[0];

      char* p_x0_rw = &x[0];  // compiles iff x is not const...

All the above pointers will hold the same value - the address of the first character in the buffer. Even an empty string has a "first character in the buffer", because C++11 guarantees to always keep an extra NUL/0 terminator character after the explicitly assigned string content (e.g. std::string("this\0that", 9) will have a buffer holding "this\0that\0").

Given any of the above pointers:

char c = p[n];   // valid for n <= x.size()
                 // i.e. you can safely read the NUL at p[x.size()]

Only for the non-const pointer p_writable_data and from &x[0]:

p_writable_data[n] = c;
p_x0_rw[n] = c;  // valid for n <= x.size() - 1
                 // i.e. don't overwrite the implementation maintained NUL

Writing a NUL elsewhere in the string does not change the string's size(); string's are allowed to contain any number of NULs - they are given no special treatment by std::string (same in C++03).

In C++03, things were considerably more complicated (key differences highlighted):

• x.data()

  • returns const char* to the string's internal buffer which wasn't required by the Standard to conclude with a NUL (i.e. might be ['h', 'e', 'l', 'l', 'o'] followed by uninitialised or garbage values, with accidental accesses thereto having undefined behaviour).
    • x.size() characters are safe to read, i.e. x[0] through x[x.size() - 1]
    • for empty strings, you're guaranteed some non-NULL pointer to which 0 can be safely added (hurray!), but you shouldn't dereference that pointer.

• &x[0]

  • for empty strings this has undefined behaviour (21.3.4)
    • e.g. given f(const char* p, size_t n) { if (n == 0) return; ...whatever... } you mustn't call f(&x[0], x.size()); when x.empty() - just use f(x.data(), ...).
  • otherwise, as per x.data() but:
    • for non-const x this yields a non-const char* pointer; you can overwrite string content

• x.c_str()

  • returns const char* to an ASCIIZ (NUL-terminated) representation of the value (i.e. ['h', 'e', 'l', 'l', 'o', '\0']).
  • although few if any implementations chose to do so, the C++03 Standard was worded to allow the string implementation the freedom to create a distinct NUL-terminated buffer on the fly, from the potentially non-NUL terminated buffer "exposed" by x.data() and &x[0]
  • x.size() + 1 characters are safe to read.
  • guaranteed safe even for empty strings (['\0']).

Consequences of accessing outside legal indices

Whichever way you get a pointer, you must not access memory further along from the pointer than the characters guaranteed present in the descriptions above. Attempts to do so have undefined behaviour, with a very real chance of application crashes and garbage results even for reads, and additionally wholesale data, stack corruption and/or security vulnerabilities for writes.

When do those pointers get invalidated?

If you call some string member function that modifies the string or reserves further capacity, any pointer values returned beforehand by any of the above methods are invalidated. You can use those methods again to get another pointer. (The rules are the same as for iterators into strings).

See also How to get a character pointer valid even after x leaves scope or is modified further below....

So, which is better to use?

From C++11, use .c_str() for ASCIIZ data, and .data() for "binary" data (explained further below).

In C++03, use .c_str() unless certain that .data() is adequate, and prefer .data() over &x[0] as it's safe for empty strings....

...try to understand the program enough to use data() when appropriate, or you'll probably make other mistakes...

The ASCII NUL '\0' character guaranteed by .c_str() is used by many functions as a sentinel value denoting the end of relevant and safe-to-access data. This applies to both C++-only functions like say fstream::fstream(const char* filename, ...) and shared-with-C functions like strchr(), and printf().

Given C++03's .c_str()'s guarantees about the returned buffer are a super-set of .data()'s, you can always safely use .c_str(), but people sometimes don't because:

• using .data() communicates to other programmers reading the source code that the data is not ASCIIZ (rather, you're using the string to store a block of data (which sometimes isn't even really textual)), or that you're passing it to another function that treats it as a block of "binary" data. This can be a crucial insight in ensuring that other programmers' code changes continue to handle the data properly.
• C++03 only: there's a slight chance that your string implementation will need to do some extra memory allocation and/or data copying in order to prepare the NUL terminated buffer

As a further hint, if a function's parameters require the (const) char* but don't insist on getting x.size(), the function probably needs an ASCIIZ input, so .c_str() is a good choice (the function needs to know where the text terminates somehow, so if it's not a separate parameter it can only be a convention like a length-prefix or sentinel or some fixed expected length).

How to get a character pointer valid even after x leaves scope or is modified further

You'll need to copy the contents of the string x to a new memory area outside x. This external buffer could be in many places such as another string or character array variable, it may or may not have a different lifetime than x due to being in a different scope (e.g. namespace, global, static, heap, shared memory, memory mapped file).

To copy the text from std::string x into an independent character array:

// USING ANOTHER STRING - AUTO MEMORY MANAGEMENT, EXCEPTION SAFE
std::string old_x = x;
// - old_x will not be affected by subsequent modifications to x...
// - you can use `&old_x[0]` to get a writable char* to old_x's textual content
// - you can use resize() to reduce/expand the string
//   - resizing isn't possible from within a function passed only the char* address

std::string old_x = x.c_str(); // old_x will terminate early if x embeds NUL
// Copies ASCIIZ data but could be less efficient as it needs to scan memory to
// find the NUL terminator indicating string length before allocating that amount
// of memory to copy into, or more efficient if it ends up allocating/copying a
// lot less content.
// Example, x == "ab\0cd" -> old_x == "ab".

// USING A VECTOR OF CHAR - AUTO, EXCEPTION SAFE, HINTS AT BINARY CONTENT, GUARANTEED CONTIGUOUS EVEN IN C++03
std::vector<char> old_x(x.data(), x.data() + x.size());       // without the NUL
std::vector<char> old_x(x.c_str(), x.c_str() + x.size() + 1);  // with the NUL

// USING STACK WHERE MAXIMUM SIZE OF x IS KNOWN TO BE COMPILE-TIME CONSTANT "N"
// (a bit dangerous, as "known" things are sometimes wrong and often become wrong)
char y[N + 1];
strcpy(y, x.c_str());

// USING STACK WHERE UNEXPECTEDLY LONG x IS TRUNCATED (e.g. Hello\0->Hel\0)
char y[N + 1];
strncpy(y, x.c_str(), N);  // copy at most N, zero-padding if shorter
y[N] = '\0';               // ensure NUL terminated

// USING THE STACK TO HANDLE x OF UNKNOWN (BUT SANE) LENGTH
char* y = alloca(x.size() + 1);
strcpy(y, x.c_str());

// USING THE STACK TO HANDLE x OF UNKNOWN LENGTH (NON-STANDARD GCC EXTENSION)
char y[x.size() + 1];
strcpy(y, x.c_str());

// USING new/delete HEAP MEMORY, MANUAL DEALLOC, NO INHERENT EXCEPTION SAFETY
char* y = new char[x.size() + 1];
strcpy(y, x.c_str());
//     or as a one-liner: char* y = strcpy(new char[x.size() + 1], x.c_str());
// use y...
delete[] y; // make sure no break, return, throw or branching bypasses this

// USING new/delete HEAP MEMORY, SMART POINTER DEALLOCATION, EXCEPTION SAFE
// see boost shared_array usage in Johannes Schaub's answer

// USING malloc/free HEAP MEMORY, MANUAL DEALLOC, NO INHERENT EXCEPTION SAFETY
char* y = strdup(x.c_str());
// use y...
free(y);

Other reasons to want a char* or const char* generated from a string

So, above you've seen how to get a (const) char*, and how to make a copy of the text independent of the original string, but what can you do with it? A random smattering of examples...

• give "C" code access to the C++ string's text, as in printf("x is '%s'", x.c_str());
• copy x's text to a buffer specified by your function's caller (e.g. strncpy(callers_buffer, callers_buffer_size, x.c_str())), or volatile memory used for device I/O (e.g. for (const char* p = x.c_str(); *p; ++p) *p_device = *p;)
• append x's text to an character array already containing some ASCIIZ text (e.g. strcat(other_buffer, x.c_str())) - be careful not to overrun the buffer (in many situations you may need to use strncat)
• return a const char* or char* from a function (perhaps for historical reasons - client's using your existing API - or for C compatibility you don't want to return a std::string, but do want to copy your string's data somewhere for the caller)
  • be careful not to return a pointer that may be dereferenced by the caller after a local string variable to which that pointer pointed has left scope
  • some projects with shared objects compiled/linked for different std::string implementations (e.g. STLport and compiler-native) may pass data as ASCIIZ to avoid conflicts

Experience has shown that JSP's have some shortcomings, one of them being hard to avoid mixing markup with actual code.

If you can, then consider using a specialized technology for what you need to do. In Java EE 6 there is JSF 2.0, which provides a lot of nice features including gluing Java beans together with JSF pages through the #{bean.method(argument)} approach.

Option 1: Insert -> Update

If you like to avoid both changes()=0 and INSERT OR IGNORE even if you cannot afford deleting the row - You can use this logic;

First, insert (if not exists) and then update by filtering with the unique key.

Example

-- Table structure
CREATE TABLE players (
    id        INTEGER       PRIMARY KEY AUTOINCREMENT,
    user_name VARCHAR (255) NOT NULL
                            UNIQUE,
    age       INTEGER       NOT NULL
);

-- Insert if NOT exists
INSERT INTO players (user_name, age)
SELECT 'johnny', 20
WHERE NOT EXISTS (SELECT 1 FROM players WHERE user_name='johnny' AND age=20);

-- Update (will affect row, only if found)
-- no point to update user_name to 'johnny' since it's unique, and we filter by it as well
UPDATE players 
SET age=20 
WHERE user_name='johnny';

Regarding Triggers

Notice: I haven't tested it to see the which triggers are being called, but I assume the following:

if row does not exists

• BEFORE INSERT
• INSERT using INSTEAD OF
• AFTER INSERT
• BEFORE UPDATE
• UPDATE using INSTEAD OF
• AFTER UPDATE

if row does exists

• BEFORE UPDATE
• UPDATE using INSTEAD OF
• AFTER UPDATE

Option 2: Insert or replace - keep your own ID

in this way you can have a single SQL command

-- Table structure
CREATE TABLE players (
    id        INTEGER       PRIMARY KEY AUTOINCREMENT,
    user_name VARCHAR (255) NOT NULL
                            UNIQUE,
    age       INTEGER       NOT NULL
);

-- Single command to insert or update
INSERT OR REPLACE INTO players 
(id, user_name, age) 
VALUES ((SELECT id from players WHERE user_name='johnny' AND age=20),
        'johnny',
        20);

Edit: added option 2.

Given a data setup like this:

The formula in cell D2 and copied down is:

=INDEX($B$2:$B$28,MATCH(1,INDEX(($A$2:$A$28=LARGE($A$2:$A$28,ROWS(D$1:D1)))*(COUNTIF(D$1:D1,$B$2:$B$28)=0),),0))

This formula will work even if there are tied OPS scores among players.

Pure POSIX shell:

#!/bin/sh
CURRENT_DIR=`pwd`

case "$CURRENT_DIR" in
  *String1*) echo "String1 present" ;;
  *String2*) echo "String2 present" ;;
  *)         echo "else" ;;
esac

Extended shells like ksh or bash have fancy matching mechanisms, but the old-style case is surprisingly powerful.

Possibly browser returns String representation of some integer value? Actually int can't be null. May be you could check for null, if value is not null, then transform String representation to int.

Have a look at Knockout-Validation which cleanly setups and uses what's described in the knockout documentation. Under: Live Example 1: Forcing input to be numeric

You can see it live in Fiddle

UPDATE: the fiddle has been updated to use the latest KO 2.0.3 and ko.validation 1.0.2 using the cloudfare CDN urls

To setup ko.validation:

ko.validation.rules.pattern.message = 'Invalid.';

ko.validation.configure({
    registerExtenders: true,
    messagesOnModified: true,
    insertMessages: true,
    parseInputAttributes: true,
    messageTemplate: null
});

To setup validation rules, use extenders. For instance:

var viewModel = {
    firstName: ko.observable().extend({ minLength: 2, maxLength: 10 }),
    lastName: ko.observable().extend({ required: true }),
    emailAddress: ko.observable().extend({  // custom message
        required: { message: 'Please supply your email address.' }
    })
};

I believe you need to specify "Option Infer On" for this to work.

Option Infer allows the compiler to make a guess at what is being represented by your code, thus it will guess that {"stuff"} is an array of strings. With "Option Infer Off", {"stuff"} won't have any type assigned to it, ever, and so it will always fail, without a type specifier.

Option Infer is, I think On by default in new projects, but Off by default when you migrate from earlier frameworks up to 3.5.

Opinion incoming:

Also, you mention that you've got "Option Explicit Off". Please don't do this.

Setting "Option Explicit Off" means that you don't ever have to declare variables. This means that the following code will silently and invisibly create the variable "Y":

Dim X as Integer
Y = 3

This is horrible, mad, and wrong. It creates variables when you make typos. I keep hoping that they'll remove it from the language.

If you have a very limited number of levels, you could try converting y into factor and change its levels.

> xy <- data.frame(x = c(1, 2, 4), y = c(1, 4, 5))
> xy$w <- as.factor(xy$y)
> levels(xy$w) <- c("good", "fair", "bad")
> xy
  x y    w
1 1 1 good
2 2 4 fair
3 4 5  bad

According to this website, it's a reference to this, mostly in loops.

$_ (dollar underscore) 'THIS' token. Typically refers to the item inside a foreach loop. Task: Print all items in a collection. Solution. ... | foreach { Write-Host $_ }

Please try this.

       <Router>
          <div>
            <Route exact path="/" component={Home} />
            <Route path="/news" component={NewsFeed} />
          </div>
        </Router> 

            

Ok so the key for me was to use the .FlattenHierarchy BindingFlag. I don't really know why I just added it on a hunch and it started working. So the final solution that allows me to get Public Instance or Static Properties is:

obj.GetType.GetProperty(propName, Reflection.BindingFlags.Public _
  Or Reflection.BindingFlags.Static Or Reflection.BindingFlags.Instance Or _
  Reflection.BindingFlags.FlattenHierarchy)

On my side, I used, with a form application:

String Directory = System.Windows.Forms.Application.StartupPath;

it takes the application startup path.

In swift 3.3 and 4. I crated APIManager class with two public methods. Just pass required parameter, api name and request type. You will get response then pass it to the closure.

It is possible to use the host_name() function

You can try one of the following methods:

rebase

For simple changes try rebasing on top of it while pulling the changes, e.g.

git pull origin master -r

So it'll apply your current branch on top of the upstream branch after fetching.

This is equivalent to: checkout master, fetch and rebase origin/master git commands.

This is a potentially dangerous mode of operation. It rewrites history, which does not bode well when you published that history already. Do not use this option unless you have read git-rebase(1) carefully.

checkout

If you don't care about your local changes, you can switch to other branch temporary (with force), and switch it back, e.g.

git checkout origin/master -f
git checkout master -f

reset

If you don't care about your local changes, try to reset it to HEAD (original state), e.g.

git reset HEAD --hard

If above won't help, it may be rules in your git normalization file (.gitattributes) so it's better to commit what it says. Or your file system doesn't support permissions, so you've to disable filemode in your git config.

You should use something similar to this for adding TextView to LinearLayout dynamically:

LinearLayout linearLayout = getActivity().findViewById(R.id.infoLayout);

TextView valueTV = new TextView(context);
valueTV.setText("hallo hallo");
valueTV.setId(Integer.parseInt("5"));
valueTV.setLayoutParams(new LinearLayout.LayoutParams(
       LinearLayout.LayoutParams.FILL_PARENT,
       LinearLayout.LayoutParams.WRAP_CONTENT));

linearLayout.addView(valueTV);

getActivity() is used for inside Fragments, you can use context or anything similar per each instance you are inside.

CER is an X.509 certificate in binary form, DER encoded.
CRT is a binary X.509 certificate, encapsulated in text (base-64) encoding.

It is not the same encoding.

You can use single command pgrep as well (doesn't require you to use pipes and multiple commands):

pgrep -fl java

you must implement IComparer interface.

In this sample I've my custom object JSONReturn, I implement my class like this :

Friend Class JSONReturnComparer
    Implements IComparer(of JSONReturn)

    Public Function Compare(x As JSONReturn, y As JSONReturn) As Integer Implements    IComparer(Of JSONReturn).Compare
        Return String.Compare(x.Name, y.Name)
    End Function

End Class

I call my sort List method like this : alResult.Sort(new JSONReturnComparer())

Maybe it could help you

For those who want to get height and width of device even when the display is resized (dynamically & in real-time):

• Step 1:

In that Component do: import { HostListener } from "@angular/core";

• Step 2:

In the component's class body write:

@HostListener('window:resize', ['$event'])
onResize(event?) {
   this.screenHeight = window.innerHeight;
   this.screenWidth = window.innerWidth;
}

• Step 3:

In the component's constructor call the onResize method to initialize the variables. Also, don't forget to declare them first.

constructor() {
  this.onResize();
}    

Complete code:

import { Component, OnInit } from "@angular/core";
import { HostListener } from "@angular/core";

@Component({
  selector: "app-login",
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.css']
})

export class FooComponent implements OnInit {
    screenHeight: number;
    screenWidth: number;

    constructor() {
        this.getScreenSize();
    }

    @HostListener('window:resize', ['$event'])
    getScreenSize(event?) {
          this.screenHeight = window.innerHeight;
          this.screenWidth = window.innerWidth;
          console.log(this.screenHeight, this.screenWidth);
    }

}

Here is a link to an excellent wiki that explains how to put greek symbols in ggplot2. In summary, here is what you do to obtain greek symbols

1. Text Labels: Use parse = T inside geom_text or annotate.
2. Axis Labels: Use expression(alpha) to get greek alpha.
3. Facet Labels: Use labeller = label_parsed inside facet.
4. Legend Labels: Use bquote(alpha == .(value)) in legend label.

You can see detailed usage of these options in the link

EDIT. The objective of using greek symbols along the tick marks can be achieved as follows

require(ggplot2);
data(tips);
p0 = qplot(sex, data = tips, geom = 'bar');
p1 = p0 + scale_x_discrete(labels = c('Female' = expression(alpha),
                                      'Male'   = expression(beta)));
print(p1);

For complete documentation on the various symbols that are available when doing this and how to use them, see ?plotmath.

Or you can always map over an iterator, without the need to build an intermediate list:

>>> _ = map(sys.stdout.write, (x for x in string.letters if x in (y for y in "BigMan on campus")))
