Just create a new DWORD(32) under the Fusion key. Name the DWORD to EnableLog, and set it to value 1. Then restart IIS, refresh the page giving errors, and the assembly bind logs will show in the error message.

I prefer TIMESTAMPDIFF because you can easily change the unit if need be.

\df+ <function_name> in psql.

You can solve this for Internet Explorer 8 by (ab)using the gradient syntax. The color format is ARGB. If you are using the Sass preprocessor you can convert colors using the built-in function "ie-hex-str()".

background: rgba(0,0,0, 0.5);
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#80000000', endColorstr='#80000000')";

Depending on your regex variant, you might be able to do simply this:

([\w-]+)

Also, you probably don't need the parentheses unless this is part of a larger expression.

Yes, if it is .NET RegEx-engine. .Net engine supports finite state machine supplied with an external stack. see details

Instead of using log4net which is an external library I have created my own simple class, highly customizable and easy to use (edit YOURNAMESPACEHERE with the namespace that you need).

CONSOLE APP

        private static readonly string LogPath = AppDomain.CurrentDomain.BaseDirectory + "logs";

        internal static void Write(LogEvent Level, string Message, bool ShowConsole = true, bool WritelogFile = true)
        {
            string Event = string.Empty;
            ConsoleColor ColorEvent = Console.ForegroundColor;

            switch (Level)

CONSOLE APP

Log.Write(LogEvent.Info, "Test message"); // It will print an info in your console, also will save a copy of this print in a .log file.
Log.Write(LogEvent.Warning, "Test message", false); // It will save the print as warning only in your .log file.
Log.Write(LogEvent.Error, "Test message", true, false); // It will print an error only in your console.

NO CONSOLE APP (ONLY LOG)

Log.Write(LogEvent.Info, "Test message"); // It will print an info in your .log file.

Here's my version:

int xmin = min(x1,x2)
  , xmax = max(x1,x2)
  , ymin = min(y1,y2)
  , ymax = max(y1,y2);

for (int i = xmin; i < xmax; ++i)
    if (ymin <= i && i <= ymax)
        return true;

return false;

Unless you're running some high-performance range-checker on billions of widely-spaced integers, our versions should perform similarly. My point is, this is micro-optimization.

checked attribute is a boolean value so "checked" value of other "string" except boolean false converts to true.

Any string value will be true. Also presence of attribute make it true:

<input type="checkbox" checked>

You can make it uncheked only making boolean change in DOM using JS.

So the answer is: they are equal.

With respect to other answers, it's not always there. Sometimes on setup process people forget to select the Web Developer Tools.

In order to fix that, one should:

1. Open Programs and Features find Visual Studios related version there, click on it,
2. Click to Change. Then the setup window will appear,
3. Select Web Developer Tools there and continue to setup.

It will download or use the setup media if exist. After the setup windows may restart, and you are ready to have fun with your Web Developer Tools now.

If I'm correct, this is a bug in webkit (according to this). I'm not sure if there is much you can do, sorry for the weak answer.

There is, however, a work around which you can use. If you add the title attribute to your image (e.g. title="Image Not Found") it'll work.

Firefox contains a dns cache. To disable the DNS cache:

1. Open your browser
2. Type in about:config in the address bar
3. Right click on the list of Properties and select New > Integer in the Context menu
4. Enter 'network.dnsCacheExpiration' as the preference name and 0 as the integer value

When disabled, Firefox will use the DNS cache provided by the OS.

After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.

It's incorrect to use zeros in date or in datetime, just put null instead of zeros.

MultipleIE , IETester there are many similar to those.

Multiple IE supports IE3 IE4.01 IE5 IE5.5 and IE6 and "is no longer maintained and there are no plans to continue maintaining it! Thanks and good luck!".

IETester seems a better choice : IE10, IE9, IE8, IE7 IE 6 and IE5.5 on Windows 8 desktop, Windows 7, Vista and XP

String.split uses Regular Expressions, also you don't need to allocate an extra array for your split.

The split-method will give you a list., the problem is that you try to pre-define how many occurrences you have of a tab, but how would you Really know that? Try using the Scanner or StringTokenizer and just learn how splitting strings work.

Let me explain Why \t does not work and why you need \\\\ to escape \\.

Okay, so when you use Split, it actually takes a regex ( Regular Expression ) and in regular expression you want to define what Character to split by, and if you write \t that actually doesn't mean \t and what you WANT to split by is \t, right? So, by just writing \t you tell your regex-processor that "Hey split by the character that is escaped t" NOT "Hey split by all characters looking like \t". Notice the difference? Using \ means to escape something. And \ in regex means something Totally different than what you think.

So this is why you need to use this Solution:

\\t

To tell the regex processor to look for \t. Okay, so why would you need two of em? Well, the first \ escapes the second, which means it will look like this: \t when you are processing the text!

Now let's say that you are looking to split \

Well then you would be left with \\ but see, that doesn't Work! because \ will try to escape the previous char! That is why you want the Output to be \\ and therefore you need to have \\\\.

I really hope the examples above helps you understand why your solution doesn't work and how to conquer other ones!

Now, I've given you this answer before, maybe you should start looking at them now.

OTHER METHODS

StringTokenizer

You should look into the StringTokenizer, it's a very handy tool for this type of work.

Example

 StringTokenizer st = new StringTokenizer("this is a test");
 while (st.hasMoreTokens()) {
     System.out.println(st.nextToken());
 }

This will output

 this
 is
 a
 test

You use the Second Constructor for StringTokenizer to set the delimiter:

StringTokenizer(String str, String delim)

Scanner

You could also use a Scanner as one of the commentators said this could look somewhat like this

Example

 String input = "1 fish 2 fish red fish blue fish";

 Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");

 System.out.println(s.nextInt());
 System.out.println(s.nextInt());
 System.out.println(s.next());
 System.out.println(s.next());

 s.close(); 

The output would be

 1
 2
 red
 blue 

Meaning that it will cut out the word "fish" and give you the rest, using "fish" as the delimiter.

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time

#!/bin/bash

path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)    
filename=log_$timestamp.txt    
log=$path$filename
days=7

START_TIME=$(date +%s)

find $path -maxdepth 1 -name "*.txt"  -type f -mtime +$days  -print -delete >> $log

echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log


... code for backup ...or any other operation .... >> $log


END_TIME=$(date +%s)

ELAPSED_TIME=$(( $END_TIME - $START_TIME ))


echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time ::  $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) "  >> $log

The code adds a few things.

• log files named with a timestamp
• log folder specified
• find looks for *.txt files only in the log folder
• type f ensures you only deletes files
• maxdepth 1 ensures you dont enter subfolders
• log files older than 7 days are deleted ( assuming this is for a backup log)
• notes the start / end time
• calculates the elapsed time for the backup operation...

Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.

Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'

Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days

-mtime +$days  --->  -mmin  +$((60*24*$days))

How I did it with a pivot in dynamic sql (#AccPurch was created prior to this)

DECLARE @sql AS nvarchar(MAX)
declare @Month Nvarchar(1000)

--DROP TABLE #temp
select distinct YYYYMM into #temp from #AccPurch AS ap
SELECT  @Month = COALESCE(@Month, '') + '[' + CAST(YYYYMM AS VarChar(8)) + '],' FROM    #temp

SELECT   @Month= LEFT(@Month,len(@Month)-1)


SET @sql = N'SELECT UserID, '+ @Month + N' into ##final_Donovan_12345 FROM (
Select ap.AccPurch ,
       ap.YYYYMM ,
       ap.UserID ,
       ap.AccountNumber
FROM #AccPurch AS ap 
) p
Pivot (SUM(AccPurch) FOR YYYYMM IN ('+@Month+ N')) as pvt'


EXEC sp_executesql @sql

Select * INTO #final From ##final_Donovan_12345

DROP TABLE  ##final_Donovan_12345

Select * From #final AS f

One more thing you have to keep in mind that the APPEND() method in Pandas doesn't modify the original object. Instead it creates a new one with combined data. Because of involving creation and data buffer, its performance is not well. You'd better use CONCAT() function when doing multi-APPEND operations.

To get the names of the employees with the 2nd highest distinct salary amount you can use.

;WITH T AS
(
SELECT *,
       DENSE_RANK() OVER (ORDER BY Salary Desc) AS Rnk
FROM Employees
)
SELECT Name
FROM T
WHERE Rnk=2;

If Salary is indexed the following may well be more efficient though especially if there are many employees.

SELECT Name
FROM   Employees
WHERE  Salary = (SELECT MIN(Salary)
                 FROM   (SELECT DISTINCT TOP (2) Salary
                         FROM   Employees
                         ORDER  BY Salary DESC) T);

Test Script

CREATE TABLE Employees
  (
     Name   VARCHAR(50),
     Salary FLOAT
  )

INSERT INTO Employees
SELECT TOP 1000000 s1.name,
                   abs(checksum(newid()))
FROM   sysobjects s1,
       sysobjects s2

CREATE NONCLUSTERED INDEX ix
  ON Employees(Salary)

SELECT Name
FROM   Employees
WHERE  Salary = (SELECT MIN(Salary)
                 FROM   (SELECT DISTINCT TOP (2) Salary
                         FROM   Employees
                         ORDER  BY Salary DESC) T);

WITH T
     AS (SELECT *,
                DENSE_RANK() OVER (ORDER BY Salary DESC) AS Rnk
         FROM   Employees)
SELECT Name
FROM   T
WHERE  Rnk = 2;

SELECT Name
FROM   Employees
WHERE  Salary = (SELECT DISTINCT TOP (1) Salary
                 FROM   Employees
                 WHERE  Salary NOT IN (SELECT DISTINCT TOP (1) Salary
                                       FROM   Employees
                                       ORDER  BY Salary DESC)
                 ORDER  BY Salary DESC)

SELECT Name
FROM   Employees
WHERE  Salary = (SELECT TOP 1 Salary
                 FROM   (SELECT TOP 2 Salary
                         FROM   Employees
                         ORDER  BY Salary DESC) sel
                 ORDER  BY Salary ASC)  

The most concise method I found can be done using in just one line:

let timeString = `${timeInSeconds/60|0}:${timeInSeconds%60}`

Explanation

`${...}`
Template literals. Allows for expressions to be converted into a string from within the string itself.
Note: Incompatible with IE.

timeInSeconds/60|0
Takes the seconds and converts in into minutes (/60). This gives a rational number. From here it is truncated using the bitwise OR (|0)

timeInSeconds%60
Remainder (modulo). Gives the remainder of the variable divided by 60.

Hours

This method can be expanded to include hours like this:

let timeString = `${timeInSeconds/60/60|0}:${timeInSeconds/60%60|0}:${timeInSeconds%60}`

Repeating this process, you can even include days.

1. JVM knows no nested classes. Nesting is just syntactic sugar.

   Below images shows Java file:

   

   Below images show class files representation of the java file :

   

   Notice that 2 class files are generated, one for parent and another for nested class.

2. Non-static nested class' objects have access to the enclosing scope. That access to the enclosing scope is maintained by holding an implicit reference of the enclosing scope object in the nested object

3. Nested class is a way to represent the intent that the nested class type represents a component of the parent class.

   public class Message {
   
   private MessageType messageType; // component of parent class
   
   public enum MessageType {
       SENT, RECEIVE;
   }
   }
   
   
   
   class Otherclass {
   
   public boolean isSent(Message message) {
       if (message.getMessageType() == MessageType.SENT) { // accessible at other places as well
           return true;
       }
       return false;
   }
   }
   

4. private static nested class represents Point#3 & the fact the nested type can only be the subcomponent to the parent class. It can't be used separately.

   public class Message {
   
    private Content content; // Component of message class
   
    private static class Content { // can only be a component of message class
   
     private String body;
     private int sentBy;
   
     public String getBody() {
        return body;
     }
   
     public int getSentBy() {
        return sentBy;
     }
   
   }
   }
   
   class Message2 {
     private Message.Content content; // Not possible
   }

Im using IONIC 5.4.13, cordova 9.0.0 ([email protected])

I might be repeating information but for me problem started appearing after adding some plugin (not sure yet). I tried all above combinations, but nothing worked. It only started working after adding:

   <base-config cleartextTrafficPermitted="true">
       <trust-anchors>
           <certificates src="system" />
       </trust-anchors>
   </base-config>

to file in project at

resources/android/xml/network_security_config.xml

so my network_security_config.xml file now looks like:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
   <base-config cleartextTrafficPermitted="true">
       <trust-anchors>
           <certificates src="system" />
       </trust-anchors>
   </base-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
        <domain includeSubdomains="true">10.1.25.10</domain>
    </domain-config>
</network-security-config>

Thanks to all.

To get the key IDs (8 bytes, 16 hex digits), this is the command which worked for me in GPG 1.4.16, 2.1.18 and 2.2.19:

gpg --list-packets <key.asc | awk '$1=="keyid:"{print$2}'

To get some more information (in addition to the key ID):

gpg --list-packets <key.asc

To get even more information:

gpg --list-packets -vvv --debug 0x2 <key.asc

The command

gpg --dry-run --import <key.asc

also works in all 3 versions, but in GPG 1.4.16 it prints only a short (4 bytes, 8 hex digits) key ID, so it's less secure to identify keys.

Some commands in other answers (e.g. gpg --show-keys, gpg --with-fingerprint, gpg --import --import-options show-only) don't work in some of the 3 GPG versions above, thus they are not portable when targeting multiple versions of GPG.

That's something I'm not sure that you can change through the HTML of the webpage itself, it's a client-side setting to tell their browser if they want security to be high. Most other browsers will not do this but from what I'm aware of this is not possible to stop unless the user disables the feature.

Does it still do what you want it to do after you click on 'Allow'? If so then it shouldn't be too much of a problem

I had the same problem because my "Dynamic Web Project" had no reference to the installed server i wanted to use and therefore had no reference to the Servlet API the server provides.

Following steps solved it without adding an extra Servlet-API to the Java Build Path (Eclipse version: Luna):

• Right click on your "Dynamic Web Project"
• Select Properties
• Select Project Facets in the list on the left side of the "Properties" wizard
• On the right side of the wizard you should see a tab named Runtimes. Select the Runtime tab and check the server you want to run the servlet.

Edit: if there is no server listed you can create a new one on the Runtimes tab

public String getFilename() 
{
/*  Intent intent = getIntent();
    String name = intent.getData().getLastPathSegment();
    return name;*/
    Uri uri=getIntent().getData();
    String fileName = null;
    Context context=getApplicationContext();
    String scheme = uri.getScheme();
    if (scheme.equals("file")) {
        fileName = uri.getLastPathSegment();
    }
    else if (scheme.equals("content")) {
        String[] proj = { MediaStore.Video.Media.TITLE };
        Uri contentUri = null;
        Cursor cursor = context.getContentResolver().query(uri, proj, null, null, null);
        if (cursor != null && cursor.getCount() != 0) {
            int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.TITLE);
            cursor.moveToFirst();
            fileName = cursor.getString(columnIndex);
        }
    }
    return fileName;
}

You shuld run file setup_xampp.bat in XAMP folder first!

You can do

orig.update(extra)

or, if you don't want orig to be modified, make a copy first:

dest = dict(orig)  # or orig.copy()
dest.update(extra)

Note that if extra and orig have overlapping keys, the final value will be taken from extra. For example,

>>> d1 = {1: 1, 2: 2}
>>> d2 = {2: 'ha!', 3: 3}
>>> d1.update(d2)
>>> d1
{1: 1, 2: 'ha!', 3: 3}

Add the following inside the end of the try/catch to avoid the error that appears when the JSP engine flushes the response via getWriter()

out.clear(); // where out is a JspWriter
out = pageContext.pushBody();

As has been noted, this isn't best practice, but it avoids the errors in your logs.

How about the ole goto statement (i know, i know, but it works just fine here ;)

DECLARE
   v_attr char(88);
CURSOR  SELECT_USERS IS
SELECT id FROM USER_TABLE
WHERE USERTYPE = 'X';
BEGIN
    FOR user_rec IN SELECT_USERS LOOP    
        BEGIN
            SELECT attr INTO v_attr 
            FROM ATTRIBUTE_TABLE
            WHERE user_id = user_rec.id;            
         EXCEPTION
            WHEN NO_DATA_FOUND THEN
               -- user does not have attribute, continue loop to next record.
               goto end_loop;
         END;

        <<end_loop>>
        null;         
    END LOOP;
END;

Just put end_loop at very end of loop of course. The null can be substituted with a commit maybe or a counter increment maybe, up to you.

If you still get Permission denied errors when you try to run your script in the docker's entrypoint, just try DO NOT use the shell form of the entrypoint:

Instead of: ENTRYPOINT ./bin/watcher write ENTRYPOINT ["./bin/watcher"]:

Here is a way to center content both vertically and horizontally in any situation, which is useful when you do not know the width or height or both:

CSS

#container {
    display: table;
    width: 300px; /* not required, just for example */
    height: 400px; /* not required, just for example */
}

#update {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

HTML

<div id="container">
    <a id="update" href="#">
        <i class="icon-refresh"></i>
    </a>
</div>

JSFiddle

Note that the width and height values are just for demonstration here, you can change them to anything you want (or remove them entirely) and it will still work because the vertical centering here is a product of the way the table-cell display property works.

This could check both prefix and key, and fetches at most 1 key.

    s3_client = boto3.client('s3')
    res = s3_client.list_objects_v2(Bucket=bucket, Prefix=prefix, MaxKeys=1)
    return 'Contents' in res

First, if your file contains binary data, then using BufferedReader would be a big mistake (because you would be converting the data to String, which is unnecessary and could easily corrupt the data); you should use a BufferedInputStream instead. If it's text data and you need to split it along linebreaks, then using BufferedReader is OK (assuming the file contains lines of a sensible length).

Regarding memory, there shouldn't be any problem if you use a decently sized buffer (I'd use at least 1MB to make sure the HD is doing mostly sequential reading and writing).

If speed turns out to be a problem, you could have a look at the java.nio packages - those are supposedly faster than java.io,

Try configuration at /config/application.rb:

config.middleware.insert_before 0, "Rack::Cors" do
  allow do
    origins '*'
    resource '*', :headers => :any, :methods => [:get, :post, :options, :delete, :put, :patch], credentials: true
  end
end

Here is a full php script to do what you're describing, though pointless. You need to read up on server-side vs. client-side. PHP can't run on the client-side, you have to use javascript to interact with the server, or put up with a page refresh. If you can't understand that, there is no way you'll be able to use my code (or anyone else's) to your benefit.

The following code performs AJAX call without jQuery, and calls the same script to stream XML to the AJAX. It then inserts your username and a <br/> in a div below the user box.

Please go back to learning the basics before trying to pursue something as advanced as AJAX. You'll only be confusing yourself in the end and potentially wasting other people's money.

<?php
    function test() {
        header("Content-Type: text/xml");
        echo "<?xml version=\"1.0\" standalone=\"yes\"?><user>".$_GET["user"]."</user>"; //output an xml document.
    }
    if(isset($_GET["user"])){
        test();
    } else {
?><html>
    <head>
        <title>Test</title>
        <script type="text/javascript">
            function do_ajax() {
                if(window.XMLHttpRequest){
                    xmlhttp=new XMLHttpRequest();
                } else {
                    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
                }
                xmlhttp.onreadystatechange = function(){
                    if (xmlhttp.readyState==4 && xmlhttp.status==200)
                    {
                        var xmlDoc = xmlhttp.responseXML;
                        data=xmlDoc.getElementsByTagName("user")[0].childNodes[0].nodeValue;
                        mydiv = document.getElementById("Test");
                        mydiv.appendChild(document.createTextNode(data));
                        mydiv.appendChild(document.createElement("br"));
                    }
                }
                xmlhttp.open("GET","<?php echo $_SERVER["PHP_SELF"]; ?>?user="+document.getElementById('username').value,true);
                xmlhttp.send();
            }
        </script>
    </head>
    <body>
        <form action="test.php" method="post">

You asked about performance. See this perf test comparing 'concat', '+' and 'join' - in short the + operator wins by far.

Update 2020, May:

Setting position: absolute and then transform: rotate(45deg) will provide a background:

div {_x000D_
  height: 200px;_x000D_
  width: 200px;_x000D_
  outline: 2px dashed slateBlue;_x000D_
  overflow: hidden;_x000D_
}_x000D_
div img {_x000D_
  position: absolute;_x000D_
  transform: rotate(45deg);_x000D_
  z-index: -1;_x000D_
  top: 40px;_x000D_
  left: 40px;_x000D_
}

<div>_x000D_
  <img src="https://placekitten.com/120/120" />_x000D_
  <h1>Hello World!</h1>_x000D_
</div>

Original Answer:

In my case, the image size is not so large that I cannot have a rotated copy of it. So, the image has been rotated with photoshop. An alternative to photoshop for rotating images is online tool too for rotating images. Once rotated, I'm working with the rotated-image in the background property.

div.with-background {
    background-image: url(/img/rotated-image.png);
    background-size:     contain;
    background-repeat:   no-repeat;
    background-position: top center;
}

Good Luck...

I have had the same problem, but none of the answers quite gave a step by step of what I needed to do. This error happens because your socket file has not been created yet. All you have to do is:

1. Start you mysql server, so your /tmp/mysql.sock is created, to do that you run: mysql server start
2. Once that is done, go to your app directory end edit the config/database.yml file and add/edit the socket: /tmp/mysql.sock entry
3. Run rake:dbmigrate once again and everything should workout fine

EDIT:

To Be Clear: If the order of your #includes matters and it is not part of your design pattern (read: you don't know why), then you need to rethink your design. Most likely, this just means you need to add the #include to the header file causing problems.

At this point, I have little interest in discussing/defending the merits of the example but will leave it up as it illustrates some nuances in the compilation process and why they result in errors.

END EDIT

You need to #include the stdint.h BEFORE you #include any other library interfaces that need it.

Example:

My LCD library uses uint8_t types. I wrote my library with an interface (Display.h) and an implementation (Display.c)

In display.c, I have the following includes.

#include <stdint.h>
#include <string.h>
#include <avr/io.h>
#include <Display.h>
#include <GlobalTime.h>

And this works.

However, if I re-arrange them like so:

#include <string.h>
#include <avr/io.h>
#include <Display.h>
#include <GlobalTime.h>
#include <stdint.h>

I get the error you describe. This is because Display.h needs things from stdint.h but can't access it because that information is compiled AFTER Display.h is compiled.

So move stdint.h above any library that need it and you shouldn't get the error anymore.

I tried with the following and it's worked:

release {
            debuggable true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

Swift 3

let button: UIButton = UIButton()
button.frame = CGRect.init(x: view.frame.width/2, y: view.frame.height/2, width: 100, height: 100)
button.setTitle(“Title Button”, for: .normal)

So there are some commands which you can use for cleaning

 1. mvn clean cache   
 2. mvn clean install 
 3. mvn clean install -Pclean-database

also deleting repository folder from .m2 can help.

You need to switch your values:

/* No greater than 900px, no less than 400px */
@media (max-width:900px) and (min-width:400px) {
    .foo {
        display:none;
    }
}?

Demo: http://jsfiddle.net/xf6gA/ (using background color, so it's easier to confirm)

I think the best way to do this is to use the Chris Boran's way, BUT you should compute MY_DIR this way:

#!/bin/sh
MY_DIR=$(dirname $(readlink -f $0))
$MY_DIR/other_script.sh

To quote the man pages for readlink:

readlink - display value of a symbolic link

...

  -f, --canonicalize
        canonicalize  by following every symlink in every component of the given 
        name recursively; all but the last component must exist

I've never encountered a use case where MY_DIR is not correctly computed. If you access your script through a symlink in your $PATH it works.

Here is what you do in Excel 2003:

1. In your sheet of interest, go to Format -> Sheet -> Hide and hide your sheet.
2. Go to Tools -> Protection -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Here is what you do in Excel 2007:

1. In your sheet of interest, go to Home ribbon -> Format -> Hide & Unhide -> Hide Sheet and hide your sheet.
2. Go to Review ribbon -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Once this is done, the sheet is hidden and cannot be unhidden without the password. Make sense?

If you really need to keep some calculations secret, try this: use Access (or another Excel workbook or some other DB of your choice) to calculate what you need calculated, and export only the "unclassified" results to your Excel workbook.

Try This and you can adjust date formate accordingly:

var today = new Date();
    var dd = today.getDate();
    var mm = today.getMonth() + 1;
    var yyyy = today.getFullYear();
    if (dd < 10) {
        dd = '0' + dd;
    }
    if (mm < 10) {
        mm = '0' + mm;
    }
 var myDate= dd + '-' + mm + '-' + yyyy;

Simple php script worked for me.

Export:

// add all job codes in the array
$jobs = array("job1", "job2", "job3");

foreach ($jobs as $value)
{
    fwrite(STDOUT, $value. " \n") or die("Unable to open file!");
    $path = "http://server1:8080/jenkins/job/".$value."/config.xml";
    $myfile = fopen($value.".xml", "w");
    fwrite($myfile, file_get_contents($path));
    fclose($myfile);
}

Import:

<?php

// add all job codes in the array
$jobs = array("job1", "job2", "job3");

foreach ($arr as $value)
{
    fwrite(STDOUT, $value. " \n") or die("Unable to open file!");
    $cmd = "java -jar jenkins-cli.jar -s http://server2:8080/jenkins/ create-job ".$value." < ".$value.".xml";
    echo exec($cmd);
}

I personally prefer to split the string by . and just return the last array element :)

var fileExt = filename.split('.').pop();

If there is no . in filename you get the entire string back.

Examples:

'some_value'                                   => 'some_value'
'.htaccess'                                    => 'htaccess'
'../images/something.cool.jpg'                 => 'jpg'
'http://www.w3schools.com/jsref/jsref_pop.asp' => 'asp'
'http://stackoverflow.com/questions/680929'    => 'com/questions/680929'

You could also use Format$(Now(), "Short Date") or whatever date format you want. Be aware, this function will return the Date as a string, so using Date() is a better approach.

I am not familiar with, react-table, so I do not know it has direct support for selecting and deselecting (it would be nice if it had).

If it does not, with the piece of code you already have you can install the onCLick handler. Now instead of trying to attach style directly to row, you can modify state, by for instance adding selected: true to row data. That would trigger rerender. Now you only have to override how are rows with selected === true rendered. Something along lines of:

// Any Tr element will be green if its (row.age > 20) 
<ReactTable
  getTrProps={(state, rowInfo, column) => {
    return {
      style: {
        background: rowInfo.row.selected ? 'green' : 'red'
      }
    }
  }}
/>

For anyone that is seeing an issue with a black preview after image capture, hiding the status bar after the UIPickerController is shown seems to fix the issue.

UIImagePickerControllerSourceType source = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] ? UIImagePickerControllerSourceTypeCamera : UIImagePickerControllerSourceTypeSavedPhotosAlbum;
UIImagePickerController *cameraController = [[UIImagePickerController alloc] init];
        cameraController.delegate = self;
        cameraController.sourceType = source;
        cameraController.allowsEditing = YES;
        [self presentViewController:cameraController animated:YES completion:^{
            //iOS 8 bug.  the status bar will sometimes not be hidden after the camera is displayed, which causes the preview after an image is captured to be black
            if (source == UIImagePickerControllerSourceTypeCamera) {
                [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
            }
        }];

Here's an example if you need to join more than 2 tables:

from d in context.dc_tpatient_bookingd
join bookingm in context.dc_tpatient_bookingm 
     on d.bookingid equals bookingm.bookingid into bookingmGroup
from m in bookingmGroup.DefaultIfEmpty()
join patient in dc_tpatient
     on m.prid equals patient.prid into patientGroup
from p in patientGroup.DefaultIfEmpty()

Ref: https://stackoverflow.com/a/17142392/2343

Had the same kind of problem and in fact the problem was not the function nor the function call, but what I passed as arguments to the function.

The function was called from the body of the script - the 'main' - so I passed "st1 a b" "st2 c d" "st3 e f" from the command line and passed it over to the function using myFunction $*

The $* causes the problem as it expands into a set of characters which will be interpreted in the call to the function using whitespace as a delimiter.

The solution was to change the call to the function in explicit argument handling from the 'main' towards the function : the call would then be myFunction "$1" "$2" "$3" which will preserve the whitespace inside strings as the quotes will delimit the arguments ... So if a parameter can contain spaces, it should be handled explicitly throughout all calls of functions.

As this may be the reason for long searches to problems, it may be wise never to use $* to pass arguments ...

Hope this helps someone, someday, somewhere ... Jan.

In case you're using virtualenvwrapper (I highly recommend doing so), you can define different hooks (preactivate, postactivate, predeactivate, postdeactivate) using the scripts with the same names in $VIRTUAL_ENV/bin/. You need the postactivate hook.

$ workon myvenv

$ cat $VIRTUAL_ENV/bin/postactivate
#!/bin/bash
# This hook is run after this virtualenv is activated.
export DJANGO_DEBUG=True
export S3_KEY=mykey
export S3_SECRET=mysecret

$ echo $DJANGO_DEBUG
True

If you want to keep this configuration in your project directory, simply create a symlink from your project directory to $VIRTUAL_ENV/bin/postactivate.

$ rm $VIRTUAL_ENV/bin/postactivate
$ ln -s .env/postactivate $VIRTUAL_ENV/bin/postactivate

You could even automate the creation of the symlinks each time you use mkvirtualenv.

Cleaning up on deactivate

Remember that this wont clean up after itself. When you deactivate the virtualenv, the environment variable will persist. To clean up symmetrically you can add to $VIRTUAL_ENV/bin/predeactivate.

$ cat $VIRTUAL_ENV/bin/predeactivate
#!/bin/bash
# This hook is run before this virtualenv is deactivated.
unset DJANGO_DEBUG

$ deactivate

$ echo $DJANGO_DEBUG

Remember that if using this for environment variables that might already be set in your environment then the unset will result in them being completely unset on leaving the virtualenv. So if that is at all probable you could record the previous value somewhere temporary then read it back in on deactivate.

Setup:

$ cat $VIRTUAL_ENV/bin/postactivate
#!/bin/bash
# This hook is run after this virtualenv is activated.
if [[ -n $SOME_VAR ]]
then
    export SOME_VAR_BACKUP=$SOME_VAR
fi
export SOME_VAR=apple

$ cat $VIRTUAL_ENV/bin/predeactivate
#!/bin/bash
# This hook is run before this virtualenv is deactivated.
if [[ -n $SOME_VAR_BACKUP ]]
then
    export SOME_VAR=$SOME_VAR_BACKUP
    unset SOME_VAR_BACKUP
else
    unset SOME_VAR
fi

Test:

$ echo $SOME_VAR
banana

$ workon myenv

$ echo $SOME_VAR
apple

$ deactivate

$ echo $SOME_VAR
banana

select column1..... from table1
where column1=''
union
select column1..... from table2
where column1= ''

In this case, it's probably because you are using the wrong brackets here:

document.getElementById['calendar'].src = loc;

should be

document.getElementById('calendar').src = loc;

import datetime
int(datetime.datetime.today().strftime('%w'))+1

this should give you your real day number - 1 = sunday, 2 = monday, etc...

There are no difference between ProcessBuilder.start() and Runtime.exec() because implementation of Runtime.exec() is:

public Process exec(String command) throws IOException {
    return exec(command, null, null);
}

public Process exec(String command, String[] envp, File dir)
    throws IOException {
    if (command.length() == 0)
        throw new IllegalArgumentException("Empty command");

    StringTokenizer st = new StringTokenizer(command);
    String[] cmdarray = new String[st.countTokens()];
    for (int i = 0; st.hasMoreTokens(); i++)
        cmdarray[i] = st.nextToken();
    return exec(cmdarray, envp, dir);
}

public Process exec(String[] cmdarray, String[] envp, File dir)
    throws IOException {
    return new ProcessBuilder(cmdarray)
        .environment(envp)
        .directory(dir)
        .start();
}

So code:

List<String> list = new ArrayList<>();
new StringTokenizer(command)
.asIterator()
.forEachRemaining(str -> list.add((String) str));
new ProcessBuilder(String[])list.toArray())
            .environment(envp)
            .directory(dir)
            .start();

should be the same as:

Runtime.exec(command)

Put the part from BEGIN....END{} inside a file and name it like my.awk.

And then execute it like below:

awk -f my.awk life.csv >output.txt

Also I see a field separator as ,. You can add that in the begin block of the .awk file as FS=","

As jQuery won't trigger native change event but only triggers its own change event. If you bind event without jQuery and then use jQuery to trigger it the callbacks you bound won't run !

The solution is then like below (100% working) :

var sortBySelect = document.querySelector("select.your-class"); 
sortBySelect.value = "new value"; 
sortBySelect.dispatchEvent(new Event("change"));

The code marked @Before is executed before each test, while @BeforeClass runs once before the entire test fixture. If your test class has ten tests, @Before code will be executed ten times, but @BeforeClass will be executed only once.

In general, you use @BeforeClass when multiple tests need to share the same computationally expensive setup code. Establishing a database connection falls into this category. You can move code from @BeforeClass into @Before, but your test run may take longer. Note that the code marked @BeforeClass is run as static initializer, therefore it will run before the class instance of your test fixture is created.

In JUnit 5, the tags @BeforeEach and @BeforeAll are the equivalents of @Before and @BeforeClass in JUnit 4. Their names are a bit more indicative of when they run, loosely interpreted: 'before each tests' and 'once before all tests'.

You'll need to use a static readonly list instead. And if you want the list to be immutable then you might want to consider using ReadOnlyCollection<T> rather than List<T>.

private static readonly ReadOnlyCollection<string> _metrics =
    new ReadOnlyCollection<string>(new[]
        {
            SourceFile.LOC,
            SourceFile.MCCABE,
            SourceFile.NOM,
            SourceFile.NOA,
            SourceFile.FANOUT,
            SourceFile.FANIN,
            SourceFile.NOPAR,
            SourceFile.NDC,
            SourceFile.CALLS
        });

public static ReadOnlyCollection<string> Metrics
{
    get { return _metrics; }
}

To Update Entire Collection,

db.getCollection('collection_name').update({},
{$set: {"field1" : "value1", "field2" : "value2", "field3" : "value3"}},
{multi: true })

Many unix-like systems (Linux, the BSDs, and OS X, at the very least) have the fts functions for directory traversal.

To recursively delete a directory, perform a depth-first traversal (without following symlinks) and remove every visited file:

int recursive_delete(const char *dir)
{
    int ret = 0;
    FTS *ftsp = NULL;
    FTSENT *curr;

    // Cast needed (in C) because fts_open() takes a "char * const *", instead
    // of a "const char * const *", which is only allowed in C++. fts_open()
    // does not modify the argument.
    char *files[] = { (char *) dir, NULL };

    // FTS_NOCHDIR  - Avoid changing cwd, which could cause unexpected behavior
    //                in multithreaded programs
    // FTS_PHYSICAL - Don't follow symlinks. Prevents deletion of files outside
    //                of the specified directory
    // FTS_XDEV     - Don't cross filesystem boundaries
    ftsp = fts_open(files, FTS_NOCHDIR | FTS_PHYSICAL | FTS_XDEV, NULL);
    if (!ftsp) {
        fprintf(stderr, "%s: fts_open failed: %s\n", dir, strerror(errno));
        ret = -1;
        goto finish;
    }

    while ((curr = fts_read(ftsp))) {
        switch (curr->fts_info) {
        case FTS_NS:
        case FTS_DNR:
        case FTS_ERR:
            fprintf(stderr, "%s: fts_read error: %s\n",
                    curr->fts_accpath, strerror(curr->fts_errno));
            break;

        case FTS_DC:
        case FTS_DOT:
        case FTS_NSOK:
            // Not reached unless FTS_LOGICAL, FTS_SEEDOT, or FTS_NOSTAT were
            // passed to fts_open()
            break;

        case FTS_D:
            // Do nothing. Need depth-first search, so directories are deleted
            // in FTS_DP
            break;

        case FTS_DP:
        case FTS_F:
        case FTS_SL:
        case FTS_SLNONE:
        case FTS_DEFAULT:
            if (remove(curr->fts_accpath) < 0) {
                fprintf(stderr, "%s: Failed to remove: %s\n",
                        curr->fts_path, strerror(curr->fts_errno));
                ret = -1;
            }
            break;
        }
    }

finish:
    if (ftsp) {
        fts_close(ftsp);
    }

    return ret;
}

Not programming related, but I'll answer anyway. It's in /etc/hosts.

You can change it with a simple text editor such as nano.

(Obviously you would need a jailbroken iphone for this)

Hack solution

You can read the text file into a String var. Then split the String into an array using a single whitespace as the delimiter StringVar.Split(" ").

The Array count would equal the number of "Words" in the file. Of course this wouldnt give you a count of line numbers.

Since I found this question not being aware, that mysql always stores time in timestamp fields in UTC but will display (e.g. phpmyadmin) in local time zone I would like to add my findings.

I have an automatically updated last_modified field, defined as:

`last_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

Looking at it with phpmyadmin, it looks like it is in local time, internally it is UTC

SET time_zone = '+04:00'; // or '+00:00' to display dates in UTC or 'UTC' if time zones are installed.
SELECT last_modified, UNIX_TIMESTAMP(last_modified), from_unixtime(UNIX_TIMESTAMP(last_modified), '%Y-%c-%d %H:%i:%s'), CONVERT_TZ(last_modified,@@session.time_zone,'+00:00') as UTC FROM `table_name`

In any constellation, UNIX_TIMESTAMP and 'as UTC' are always displayed in UTC time.

Run this twice, first without setting the time_zone.

So that works fine, but how on earth do you give the buttons margins so there is space between them?

You call setMargins() on the LinearLayout.LayoutParams object.

I tried using LinearLayout.MarginLayoutParams, but that has no weight member so it's no good.

LinearLayout.LayoutParams is a subclass of LinearLayout.MarginLayoutParams, as indicated in the documentation.

Is this impossible?

No.

it wouldn't be the first Android layout task you can only do in XML

You are welcome to supply proof of this claim.

Personally, I am unaware of anything that can only be accomplished via XML and not through Java methods in the SDK. In fact, by definition, everything has to be doable via Java (though not necessarily via SDK-reachable methods), since XML is not executable code. But, if you're aware of something, point it out, because that's a bug in the SDK that should get fixed someday.

If you are trying to load a file which is not in the same directory as your Java class, you've got to use the runtime directory structure rather than the one which appears at design time.

To find out what the runtime directory structure is, check your {root project dir}/target/classes directory. This directory is accessible via the "." URL.

Based on user4284592's answer, the following worked for me:

ClassLoader cl = getClass().getClassLoader();
File file = new File(cl.getResource("./docs/doc.pdf").getFile());

with the following directory structure:

{root dir}/target/classes/docs/doc.pdf

Here's an explanation, so you don't just blindly copy and paste my code:

• java.lang.ClassLoader is an object that is responsible for loading classes. Every Class object contains a reference to the ClassLoader that defined it and can fetch it with getClassLoader() method.
• ClassLoader's getResource method finds the resource with the given name. A resource is some data that can be accessed by class code in a way that is independent of the location of the code.

Please see this code sample in codesandbox

https://codesandbox.io/s/pagino-13pit

import Pagino from "pagino";
import { useState, useMemo } from "react";

export default function App() {
  const [pages, setPages] = useState([]);

  const pagino = useMemo(() => {
    const _ = new Pagino({
      showFirst: false,
      showLast: false,
      onChange: (page, count) => setPages(_.getPages())
    });

    _.setCount(10);

    return _;
  }, []);

  const hanglePaginoNavigation = (type) => {
    if (typeof type === "string") {
      pagino[type]?.();
      return;
    }

    pagino.setPage(type);
  };

  return (
    <div>
      <h1>Page: {pagino.page}</h1>
      <ul>
        {pages.map((page) => (
          <button key={page} onClick={() => hanglePaginoNavigation(page)}>
            {page}
          </button>
        ))}
      </ul>
    </div>
  );
}

Want to align an image which have after a text / title and both are inside a div?

See on JSfiddle or Run Code Snippet.

Just be sure to have an ID or a class at all your elements (div, img, title, etc.).

For me works this solution on all browsers (for mobile devices you must to adapt your code with: @media).

h2.h2red {_x000D_
    color: red;_x000D_
    font-size: 14px;_x000D_
}_x000D_
.mydivclass {_x000D_
    margin-top: 30px;_x000D_
    display: block;_x000D_
}_x000D_
img.mydesiredclass {_x000D_
    margin-right: 10px;_x000D_
    display: block;_x000D_
    float: left; /* If you want to allign the text with an image on the same row */_x000D_
    width: 100px;_x000D_
    heght: 100px;_x000D_
    margin-top: -40px /* Change this value to adapt to your page */;_x000D_
}

<div class="mydivclass">_x000D_
    <br />_x000D_
    <img class="mydesiredclass" src="https://upload.wikimedia.org/wikipedia/commons/thumb/b/b3/Wikipedia-logo-v2-en.svg/2000px-Wikipedia-logo-v2-en.svg.png">_x000D_
    <h2 class="h2red">Text aligned after image inside a div by negative manipulate the img position</h2>_x000D_
</div>

Being more generic, passing values from calling element (which is easier to maintain).

• Specify the start condition in the text field (display:none)
• Pass the required option value to show/hide on ("Other")
• Pass the target and field to show/hide ("TitleOther")

function showHideEle(selectSrc, targetEleId, triggerValue) { _x000D_
 if(selectSrc.value==triggerValue) {_x000D_
  document.getElementById(targetEleId).style.display = "inline-block";_x000D_
 } else {_x000D_
  document.getElementById(targetEleId).style.display = "none";_x000D_
 }_x000D_
} 

<select id="Title"_x000D_
   onchange="showHideEle(this, 'TitleOther', 'Other')">_x000D_
      <option value="">-- Choose</option>_x000D_
      <option value="Mr">Mr</option>_x000D_
      <option value="Mrs">Mrs</option>_x000D_
      <option value="Miss">Miss</option>_x000D_
      <option value="Other">Other --&gt;</option>      _x000D_
</select>_x000D_
<input id="TitleOther" type="text" title="Title other" placeholder="Other title" _x000D_
    style="display:none;"/>

Since React 0.12 the API is slightly changed. The valid code to initialize myChild would be the following:

var Child = React.createClass({…});
var myChild = React.render(React.createElement(Child, {}), mountNode);
myChild.someMethod();

I was looking for a way to do this myself without adding an extra dependency to the classpath. After some investigation I found that it is possible as long as you have a generic supertype. This was OK for me as I was working with a DAO layer with a generic layer supertype. If this fits your scenario then it's the neatest approach IMHO.

Most generics use cases I've come across have some kind of generic supertype e.g. List<T> for ArrayList<T> or GenericDAO<T> for DAO<T>, etc.

Pure Java solution

The article Accessing generic types at runtime in Java explains how you can do it using pure Java.

@SuppressWarnings("unchecked")
public GenericJpaDao() {
  this.entityBeanType = ((Class) ((ParameterizedType) getClass()
      .getGenericSuperclass()).getActualTypeArguments()[0]);
}

Spring solution

My project was using Spring which is even better as Spring has a handy utility method for finding the type. This is the best approach for me as it looks neatest. I guess if you weren't using Spring you could write your own utility method.

import org.springframework.core.GenericTypeResolver;

public abstract class AbstractHibernateDao<T extends DomainObject> implements DataAccessObject<T>
{

    @Autowired
    private SessionFactory sessionFactory;

    private final Class<T> genericType;

    private final String RECORD_COUNT_HQL;
    private final String FIND_ALL_HQL;

    @SuppressWarnings("unchecked")
    public AbstractHibernateDao()
    {
        this.genericType = (Class<T>) GenericTypeResolver.resolveTypeArgument(getClass(), AbstractHibernateDao.class);
        this.RECORD_COUNT_HQL = "select count(*) from " + this.genericType.getName();
        this.FIND_ALL_HQL = "from " + this.genericType.getName() + " t ";
    }

You can make it so:

type MessageType int32

const (
    TEXT   MessageType = 0
    BINARY MessageType = 1
)

With this code compiler should check type of enum

if you are creating one object and adding it to the list that you use in your adapter , when you change one element of your list in the adapter all of your other items change too in other words its all about references and your list doesn't hold separate copies of that single object.

using (StreamWriter writer = new StreamWriter(File.Open(@"E:\Sample.txt", FileMode.Append), Encoding.GetEncoding(1250)))  ////File.Create(path)
        {
            writer.Write("Sample Text");
        }

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

I don't have enough reputation to comment on the relevant answers, but to people reading this; adding .btn does not just add the pointer cursor but adds a lot of other styling as well. Which is great if it's a button and you want the bootstap button styling, but in other cases it would mess a lot up for other elements.

The best thing you can do, like Hari Das suggested, and which I also always do, is to add the following css:

.cursor-pointer {
  cursor: pointer;
}

After which you can add it to any element

<div class="cursor-pointer"> .. </div>

There is no way to decrypt MD5. Well, there is, but no reasonable way to do it. That's kind of the point.

To check if someone is entering the correct password, you need to MD5 whatever the user entered, and see if it matches what you have in the database.

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

Probably you haven't injected $http service to your controller. There are several ways of doing that.

Please read this reference about DI. Then it gets very simple:

function MyController($scope, $http) {
   // ... your code
}

An other solution:

interface bar {
    length: number;
}

bars = [{
  length: 1
} as bar];

I've wrestled with this myself, trying to make it work from the server. Couldn't. Instead...

1. To clarify on @dnc253's answer, $window.open(URL) is a method for having an Angular application open a given URL in another window. (It's really just a testable angular proxy for the universal window.open().) This is a great solution, preserves your history, and gets the file downloaded and possibly renders it in that fresh browser window if that's supported. But it often runs into popup blockers, which is a huge problem for reliability. Users often simply don't understand what's going on with them. So, if you don't mind immediately downloading the file with the current window, you can simply use the equally effective universal javascript method: location.href = "uriString", which works like a charm for me. Angular doesn't even realize anything has happened. I call it in a promise handler for once my POST/PUT operation has completed. If need be, have the POST/PUT return the URL to call, if you can't already infer it. You'll get the same behavior for the user as if it had downloaded in response to the PUT/POST. For example:

   $http.post(url, payload).then(function(returnData){
       var uriString = parseReturn(returnData);
       location.href="uriString"
   })
   

2. You can, in fact, download something directly from an XHR request, but it requires full support for the HTML5 file API and is usually more trouble than it's worth unless you need to perform local transformations upon the file before you make it available to the user. (Sadly, I lack the time to provide details on that but there are other SO posts about using it.)

This technique is usually used for multiple axis in a figure. In this context it is often required to have a colorbar that corresponds in size with the result from imshow. This can be achieved easily with the axes grid tool kit:

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

data = np.arange(100, 0, -1).reshape(10, 10)

fig, ax = plt.subplots()
divider = make_axes_locatable(ax)
cax = divider.append_axes('right', size='5%', pad=0.05)

im = ax.imshow(data, cmap='bone')

fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

You can explicitly format the query to produce a delimited string with something along the lines of:

select '"'||foo||'","'||bar||'"'
  from tab

And set up the output options as appropriate. As an option, the COLSEP variable on SQLPlus will let you produce delimited files without having to explicitly generate a string with the fields concatenated together. However, you will have to put quotes around strings on any columns that might contain embedded comma characters.

SELECT 
    T.NAME AS 'TABLE NAME',
    P.[ROWS] AS 'NO OF ROWS'
FROM SYS.TABLES T 
INNER JOIN  SYS.PARTITIONS P ON T.OBJECT_ID=P.OBJECT_ID;

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

Call c_str() to get a const char * (LPCSTR) from a std::string.

It's all in the name:

LPSTR - (long) pointer to string - char *

LPCSTR - (long) pointer to constant string - const char *

LPWSTR - (long) pointer to Unicode (wide) string - wchar_t *

LPCWSTR - (long) pointer to constant Unicode (wide) string - const wchar_t *

LPTSTR - (long) pointer to TCHAR (Unicode if UNICODE is defined, ANSI if not) string - TCHAR *

LPCTSTR - (long) pointer to constant TCHAR string - const TCHAR *

You can ignore the L (long) part of the names -- it's a holdover from 16-bit Windows.

to link dynamic and static library within one line, you must put static libs after dynamic libs and object files, like this:

gcc -lssl main.o -lFooLib -o main

otherwise, it will not work. it does take me sometime to figure it out.

I had a similar requirement; documenting my approach here for anyone with a similar scenario...

Scenario

• I have a database from a clean install with the correct collations.
• I have another database which has the wrong collations.
• I need to update the latter to use the collations defined on the former.

Solution

Use SQL Server Schema Comparison (from SQL Server Data Tools / Visual Studio) to compare source (clean install) with destination (the db with invalid collation).

In my case I compared the two DBs directly; though you could work via a project to allow you to manually tweak pieces in between...

• Run Visual Studio
• Create a new SQL Server Data Project
• Click Tools, SQL Server, New Schema Comparison
• Select the source database
• Select the target database
• Click options (?)
  • Under Object Types select only those types you're interested in (for me it was only Views and Tables)
  • Under General select:
    • Block on possible data loss
    • Disable & reenable DDL triggers
    • Ignore cryptographic provider file path
    • Ignore File & Log File Path
    • Ignore file size
    • Ignore filegroup placement
    • Ignore full text catalog file path
    • Ignore keyword casing
    • Ignore login SIDs
    • Ignore quoted identifiers
    • Ignore route lifetime
    • Ignore semicolon between statements
    • Ignore whitespace
    • Script refresh module
    • Script validation for new constraints
    • Verify collation compatibility
    • Verify deployment
• Click Compare
  • Uncheck any objects flagged for deletion (NB: those may still have collation issues; but since they're not defined in our source/template db we don't know; either way, we don't want to lose things if we're only targeting collation changes). You can unchceck all at once by right clicking on the DELETE folder and selecting EXCLUDE.
  • Likewise exclude for any CREATE objects (here since they don't exist in the target they can't have the wrong collation there; whether they should exist is a question for another topic).
  • Click on each object under CHANGE to see the script for that object. Use the diff to ensure that we're only changing the collation (anything other differences manually detected you'll likely want to exclude / handle those objects manually).
• Click Update to push changes

This does still involve some manual effort (e.g. checking that you're only impacting the collation) - but it handles dependencies for you.

Also you can keep a database project of the valid schema so you can use a universal template for your DBs should you have more than 1 to update, assuming all target DBs should end up with the same schema.

You can also use find/replace on the files in a database project should you wish to mass amend settings there (e.g. so you could create the project from the invalid database using schema compare, amend the project files, then toggle the source/target in the schema compare to push your changes back to the DB).

One thing many Java programmers don't know is that Strings are immutable, so use StringBuilder or StringBuffer!

String s = "";
for(int i = 0; i < 100; i++) {
  s += "Strings " + "are " + "immutable, " + " so use StringBuilder/StringBuffer to reduce memory footprint";
}

You can pass values by using the below .

@Html.ActionLink("About", "About", "Home",new { name = ViewBag.Name }, htmlAttributes:null )

Controller:

public ActionResult About(string name)
        {
            ViewBag.Message = "Your application description page.";
            ViewBag.NameTransfer = name;
            return View();
        }

And the URL looks like

http://localhost:50297/Home/About?name=My%20Name%20is%20Vijay

All you need to do is add \n or to write on files go \r\n.

Examples:

say you wanted to write duck(line break) cow this is how you would do it Console.WriteLine("duck\n cow");

Edit: I think I didn't understand the question. You can use

@"duck
cow".Replace("\r\n", "")

as a linebreak in code, that produces \r\n which is used Windows.

Doesn't look like you got an answer but this problem can also creep up if you're passing null ID's into your JPA Predicate.

For instance.

If I did a query on Cats to get back a list. Which returns 3 results.

List catList;

I then iterate over that List of cats and store a foriegn key of cat perhaps leashTypeId in another list.

List<Integer> leashTypeIds= new ArrayList<>();

for(Cats c : catList){
    leashTypeIds.add(c.getLeashTypeId);
}

jpaController().findLeashes(leashTypeIds);

If any of the Cats in catList have a null leashTypeId it will throw this error when you try to query your DB.

(Just realized I am posting on a 5 year old thread, perhaps someone will find this useful)

Adding this into my styles.xml worked for me

<item name="android:textColorPrimary">?android:attr/textColorPrimaryInverse</item>

You can use Programmatic Navigation.In order to go back, you use this:

router.go(n) 

Where n can be positive or negative (to go back). This is the same as history.back().So you can have your element like this:

<a @click="$router.go(-1)">back</a>

Specifying a non-static position, e.g., position: absolute/relative on a node means that it will be used as the reference for absolutely positioned elements within it http://jsfiddle.net/E5eEk/1/

See https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Positioning#Positioning_contexts

We can change the positioning context — which element the absolutely positioned element is positioned relative to. This is done by setting positioning on one of the element's ancestors.

Just to add something I was missing from all the answers - even if it seems to be silly and obvious as soon as you know:

The file has to be named "App.config" or "app.config" and can be located in your project at the same level as e.g. Program.cs.

I do not know if other locations are possible, other names (like application.conf, as suggested in the ODP.net documentation) did not work for me.

PS. I started with Visual Studio Code and created a new project with "dotnet new". No configuration file is created in this case, I am sure there are other cases. PPS. You may need to add a nuget package to be able to read the config file, in case of .NET CORE it would be "dotnet add package System.Configuration.ConfigurationManager --version 4.5.0"

The only valid answer would be the pause command.

Though this does not wait specifically for the 'ENTER' key, it waits for any key that is pressed.

And just in case you want it convenient for the user, pause is the best option.

I had this problem too. The route of my problem was I had made a mistake in my vhosts.conf file. If you are using vhosts this is another thing to check

You can Try using :- git ls-files -s

Follow this: Open your config file

vi /etc/nginx/conf.d/default.conf

Change port number on which you are listening;

listen       81;
server_name  localhost;

Add a rule to iptables

 vi /etc/sysconfig/iptables 
-A INPUT -m state --state NEW -m tcp -p tcp --dport 81 -j ACCEPT

Restart IPtables

 service iptables restart;

Restart the nginx server

service nginx restart

Access yr nginx server files on port 81

First, and most important - all Spring beans are managed - they "live" inside a container, called "application context".

Second, each application has an entry point to that context. Web applications have a Servlet, JSF uses a el-resolver, etc. Also, there is a place where the application context is bootstrapped and all beans - autowired. In web applications this can be a startup listener.

Autowiring happens by placing an instance of one bean into the desired field in an instance of another bean. Both classes should be beans, i.e. they should be defined to live in the application context.

What is "living" in the application context? This means that the context instantiates the objects, not you. I.e. - you never make new UserServiceImpl() - the container finds each injection point and sets an instance there.

In your controllers, you just have the following:

@Controller // Defines that this class is a spring bean
@RequestMapping("/users")
public class SomeController {

    // Tells the application context to inject an instance of UserService here
    @Autowired
    private UserService userService;

    @RequestMapping("/login")
    public void login(@RequestParam("username") String username,
           @RequestParam("password") String password) {

        // The UserServiceImpl is already injected and you can use it
        userService.login(username, password);

    }
}

A few notes:

• In your applicationContext.xml you should enable the <context:component-scan> so that classes are scanned for the @Controller, @Service, etc. annotations.
• The entry point for a Spring-MVC application is the DispatcherServlet, but it is hidden from you, and hence the direct interaction and bootstrapping of the application context happens behind the scene.
• UserServiceImpl should also be defined as bean - either using <bean id=".." class=".."> or using the @Service annotation. Since it will be the only implementor of UserService, it will be injected.
• Apart from the @Autowired annotation, Spring can use XML-configurable autowiring. In that case all fields that have a name or type that matches with an existing bean automatically get a bean injected. In fact, that was the initial idea of autowiring - to have fields injected with dependencies without any configuration. Other annotations like @Inject, @Resource can also be used.

Yes, it's possible, from @Fábio Zangirolami answer

audio::-webkit-media-controls-panel, video::-webkit-media-controls-panel {
                background-color: red;
}

The align-items, or respectively align-content attribute controls this behaviour.

align-items defines the items' positioning perpendicularly to flex-direction.

The default flex-direction is row, therfore vertical placement can be controlled with align-items.

There is also the align-self attribute to control the alignment on a per item basis.

#a {_x000D_
  display:flex;_x000D_
_x000D_
  align-items:flex-start;_x000D_
  align-content:flex-start;_x000D_
  }_x000D_
_x000D_
#a > div {_x000D_
  _x000D_
  background-color:red;_x000D_
  padding:5px;_x000D_
  margin:2px;_x000D_
  }_x000D_
 #a > #c {_x000D_
  align-self:stretch;_x000D_
 }

<div id="a">_x000D_
  _x000D_
  <div id="b">left</div>_x000D_
  <div id="c">middle</div>_x000D_
  <div>right<br>right<br>right<br>right<br>right<br></div>_x000D_
  _x000D_
</div>

css-tricks has an excellent article on the topic. I recommend reading it a couple of times.

The easiest way to do it is to make the display an inline block

<div id='page' style='width: 600px'>
  <h1 style='border:2px black solid; font-size:42px; display: inline-block;'>Title</h1>
</div>

if you do this it should work

If you do an "Add" it will add it to the bottom of the list. You need to do an "Insert" if you want the item added to the top of the list.

Make sure "Start In" does NOT end with a BACKSLASH.

this will subtract ten days of the current date (before Java 8):

int x = -10;
Calendar cal = GregorianCalendar.getInstance();
cal.add( Calendar.DAY_OF_YEAR, x);
Date tenDaysAgo = cal.getTime();

If you're using Java 8 you can make use of the new Date & Time API (http://www.oracle.com/technetwork/articles/java/jf14-date-time-2125367.html):

LocalDate tenDaysAgo = LocalDate.now().minusDays(10);

For converting the new to the old types and vice versa see: Converting between java.time.LocalDateTime and java.util.Date

ire_and_curses's suggestion of using tar c <dir> has some issues:

• tar processes directory entries in the order which they are stored in the filesystem, and there is no way to change this order. This effectively can yield completely different results if you have the "same" directory on different places, and I know no way to fix this (tar cannot "sort" its input files in a particular order).
• I usually care about whether groupid and ownerid numbers are the same, not necessarily whether the string representation of group/owner are the same. This is in line with what for example rsync -a --delete does: it synchronizes virtually everything (minus xattrs and acls), but it will sync owner and group based on their ID, not on string representation. So if you synced to a different system that doesn't necessarily have the same users/groups, you should add the --numeric-owner flag to tar
• tar will include the filename of the directory you're checking itself, just something to be aware of.

As long as there is no fix for the first problem (or unless you're sure it does not affect you), I would not use this approach.

The find based solutions proposed above are also no good because they only include files, not directories, which becomes an issue if you the checksumming should keep in mind empty directories.

Finally, most suggested solutions don't sort consistently, because the collation might be different across systems.

This is the solution I came up with:

dir=<mydir>; (find "$dir" -type f -exec md5sum {} +; find "$dir" -type d) | LC_ALL=C sort | md5sum

Notes about this solution:

• The LC_ALL=C is to ensure reliable sorting order across systems
• This doesn't differentiate between a directory "named\nwithanewline" and two directories "named" and "withanewline", but the chance of that occuring seems very unlikely. One usually fixes this with a -print0 flag for find but since there's other stuff going on here, I can only see solutions that would make the command more complicated then it's worth.

PS: one of my systems uses a limited busybox find which does not support -exec nor -print0 flags, and also it appends '/' to denote directories, while findutils find doesn't seem to, so for this machine I need to run:

dir=<mydir>; (find "$dir" -type f | while read f; do md5sum "$f"; done; find "$dir" -type d | sed 's#/$##') | LC_ALL=C sort | md5sum

Luckily, I have no files/directories with newlines in their names, so this is not an issue on that system.

i prefer to use ng-value with ng-if, [ng-value] will handle trigger changes

<input type="radio"  name="isStudent" ng-model="isStudent" ng-value="true" />

//to show and hide input by removing it from the DOM, that's make me secure from malicious data

<input type="text" ng-if="isStudent"  name="textForStudent" ng-model="job">

Use this library:

npm install flat

Usage (from https://www.npmjs.com/package/flat):

Flatten:

    var flatten = require('flat')


    flatten({
        key1: {
            keyA: 'valueI'
        },
        key2: {
            keyB: 'valueII'
        },
        key3: { a: { b: { c: 2 } } }
    })

    // {
    //   'key1.keyA': 'valueI',
    //   'key2.keyB': 'valueII',
    //   'key3.a.b.c': 2
    // }

Un-flatten:

var unflatten = require('flat').unflatten

unflatten({
    'three.levels.deep': 42,
    'three.levels': {
        nested: true
    }
})

// {
//     three: {
//         levels: {
//             deep: 42,
//             nested: true
//         }
//     }
// }

For me this was the issue. This whole block was missing from the section.

        </h4>
    </div>
    <div id="collapseExample" class="panel-collapse collapse in">
        <div class="panel-body">
            Panel content
        </div>
    </div>

You have to cast the selected item to your custom class (ComboboxItem) Try this:

{
ComboBox cmb = (ComboBox)sender;
            int selectedIndex = cmb.SelectedIndex;
            string selectedText = this.comboBox1.Text;
            string selectedValue = ((ComboboxItem)cmb.SelectedItem).Value.ToString();

ComboboxItem selectedCar = (ComboboxItem)cmb.SelectedItem;
MessageBox.Show(String.Format("Index: [{0}] CarName={1}; Value={2}", selectedIndex, selectedCar.Text, selecteVal));        

}

You need to have your DBA modify the init.ora file, adding the directory you want to access to the 'utl_file_dir' parameter. Your database instance will then need to be stopped and restarted because init.ora is only read when the database is brought up.

You can view (but not change) this parameter by running the following query:

SELECT *
  FROM V$PARAMETER
  WHERE NAME = 'utl_file_dir'

Share and enjoy.

You can insert using a Sub-query as follows:

INSERT INTO new_table (columns....)
SELECT columns....
FROM initial_table where column=value

cat can be the easy solution but that become very slow when we concat large files, find -print is to rescue you, though you have to use cat once.

I like to use a rolling file appender to write the logging info to a file. My log4j properties file typically looks something like this.

It depends on what type of fading you are looking for.

But with shadow and rounded corners you can get a nice result. Rounded corners because the bigger the shadow, the weirder it will look in the edges unless you balance it out with rounded corners.

In .NET 4 you don't need the ToArray() call - string.Join is overloaded to accept IEnumerable<T> or just IEnumerable<string>.

There are potentially more efficient ways of doing it before .NET 4, but do you really need them? Is this actually a bottleneck in your code?

You could iterate over the list, work out the final size, allocate a StringBuilder of exactly the right size, then do the join yourself. That would avoid the extra array being built for little reason - but it wouldn't save much time and it would be a lot more code.

In case anyone else is interested to know how to import files/packages from gdrive inside a google colab. The following procedure worked for me:

1) Mount your google drive in google colab:

from google.colab import drive
drive.mount('/content/gdrive/')

2) Append the directory to your python path using sys:

import sys
sys.path.append('/content/gdrive/mypythondirectory')

Now you should be able to import stuff from that directory!

To center the ul and also have the li elements centered in it as well, and make the width of the ul change dynamically, use display: inline-block; and wrap it in a centered div.

Update

Here is a jsFiddle link to the code above.

You can loop the array with a for loop and the object properties with for-in loops.

for (var i=0; i<result.length; i++)
    for (var name in result[i]) {
        console.log("Item name: "+name);
        console.log("Source: "+result[i][name].sourceUuid);
        console.log("Target: "+result[i][name].targetUuid);
    }

If you're like me, and would rather not make this security hole system or user-wide, then you can add a config option to any git repos that need this by running this command in those repos. (note only works with git version >= 2.10, released 2016-09-04)

git config core.sshCommand 'ssh -oHostKeyAlgorithms=+ssh-dss'

This only works after the repo is setup however. If you're not comfortable adding a remote manually (and just want to clone) then you can run the clone like this:

GIT_SSH_COMMAND='ssh -oHostKeyAlgorithms=+ssh-dss' git clone ssh://user@host/path-to-repository

then run the first command to make it permanent.

If you don't have the latest, and still would like to keep the hole as local as possible I recommend putting

export GIT_SSH_COMMAND='ssh -oHostKeyAlgorithms=+ssh-dss'

in a file somewhere, say git_ssh_allow_dsa_keys.sh, and sourceing it when needed.

you can use these styles:

style="border-left: 1px solid #cdd0d4;"  
style="border-bottom: 1px solid #cdd0d4;"
style="border-top: 1px solid #cdd0d4;"
style="border-right: 1px solid #cdd0d4;"

with this you want u must use

<td style="border-left: 1px solid #cdd0d4;border-bottom: 1px solid #cdd0d4;">  

or

<img style="border-left: 1px solid #cdd0d4;border-bottom: 1px solid #cdd0d4;"> 

UPDATE table_name 
SET field = replace(field, 'string-to-find', 'string-that-will-replace-it');

You could try using vw for height. https://developer.mozilla.org/en/docs/Web/CSS/length

Something like

div#map {
     width: 100%;
     height: 60vw;
}

This would set the width of the div to 60% of the viewport width. You will probably need to use calc to adjust to take padding into account …

After my initial research i found that when we close a browser, the browser will close all the tabs one by one to completely close the browser. Hence, i observed that there will be very little time delay between closing the tabs. So I taken this time delay as my main validation point and able to achieve the browser and tab close event detection.

//Detect Browser or Tab Close Events
$(window).on('beforeunload',function(e) {
  e = e || window.event;
  var localStorageTime = localStorage.getItem('storagetime')
  if(localStorageTime!=null && localStorageTime!=undefined){
    var currentTime = new Date().getTime(),
        timeDifference = currentTime - localStorageTime;

    if(timeDifference<25){//Browser Closed
       localStorage.removeItem('storagetime');
    }else{//Browser Tab Closed
       localStorage.setItem('storagetime',new Date().getTime());
    }

  }else{
    localStorage.setItem('storagetime',new Date().getTime());
  }
});

Change your second style to this:

input, select, textarea{
    color: #ff0000;
}

At the moment, you are telling the form to change the text to black once the focus is off. The above remedies that.

Also, it is a good idea to place the normal state styles ahead of the :focus and :hover styles in your stylesheet. That helps prevent this problem. So

input, select, textarea{
    color: #ff0000;
}

textarea:focus, input:focus {
    color: #ff0000;
}

I ran across this error recently using a javascript library which changes the parameters of a function based on conditions.

You can test an object to see if it has the function. I would only do this in scenarios where you don't control what is getting passed to you.

if( param.indexOf != undefined ) {
   // we have a string or other object that 
   // happens to have a function named indexOf
}

You can test this in your browser console:

> (3).indexOf == undefined;
true

> "".indexOf == undefined;
false

Normally your requirements.txt file would look something like this:

package-one==1.9.4
package-two==3.7.1
package-three==1.0.1
...

To specify a Github repo, you do not need the package-name== convention.

The examples below update package-two using a GitHub repo. The text between @ and # denotes the specifics of the package.

Specify commit hash (41b95ec in the context of updated requirements.txt):

package-one==1.9.4
git+git://github.com/path/to/package-two@41b95ec#egg=package-two
package-three==1.0.1

Specify branch name (master):

git+git://github.com/path/to/package-two@master#egg=package-two

Specify tag (0.1):

git+git://github.com/path/to/[email protected]#egg=package-two

Specify release (3.7.1):

git+git://github.com/path/to/package-two@releases/tag/v3.7.1#egg=package-two

Note that #egg=package-two is not a comment here, it is to explicitly state the package name

This blog post has some more discussion on the topic.

std::max_element takes two iterators delimiting a sequence and returns an iterator pointing to the maximal element in that sequence. You can additionally pass a predicate to the function that defines the ordering of elements.

For List<List<List<x>>> and so on, use

list.SelectMany(x => x.SelectMany(y => y)).ToList();

This has been posted in a comment, but it does deserves a separate reply in my opinion.

Use $('textarea').val('').

The problem with using $('textarea').text('') , or $('textarea').html('') for that matter is that it will only erase what was in the original DOM sent by the server. If a user clears it and then enters new input, the clear button will no longer work. Using .val('') handles the user input case properly.

You are accesing localhost, meaning you have a web server running on your machine. To access it from Internet, you need to assign a public IP address to your machine. Then you can access http://<public_ip>:<port>/. Port number is normally 80.

var checkboxes = document.getElementsByName('location[]');
var vals = "";
for (var i=0, n=checkboxes.length;i<n;i++) 
{
    if (checkboxes[i].checked) 
    {
        vals += ","+checkboxes[i].value;
    }
}
if (vals) vals = vals.substring(1);

We use AttachedCommandBehavior for this. You can attach any event to a command on your view model avoiding any code behind.

Installs package from git and save to your bower.json dependency block.

1. bower register package-name git-endpoint#version
2. install package-name --save

(--save will save the package name version in the bower.json file inside the dependency block).

Reference

The best way is to store native JavaScript Date objects, which map onto BSON native Date objects.

> db.test.insert({date: ISODate()})
> db.test.insert({date: new Date()})
> db.test.find()
{ "_id" : ObjectId("..."), "date" : ISODate("2014-02-10T10:50:42.389Z") }
{ "_id" : ObjectId("..."), "date" : ISODate("2014-02-10T10:50:57.240Z") }

The native type supports a whole range of useful methods out of the box, which you can use in your map-reduce jobs, for example.

If you need to, you can easily convert Date objects to and from Unix timestamps¹⁾, using the getTime() method and Date(milliseconds) constructor, respectively.

¹⁾ Strictly speaking, the Unix timestamp is measured in seconds. The JavaScript Date object measures in milliseconds since the Unix epoch.

Example Bold text:

UILabel *titleBold = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 200, 30)];
UIFont* myBoldFont = [UIFont boldSystemFontOfSize:[UIFont systemFontSize]];
[titleBold setFont:myBoldFont];

Example Italic text:

UILabel *subTitleItalic = [[UILabel alloc] initWithFrame:CGRectMake(10, 35, 200, 30)];
UIFont* myItalicFont = [UIFont italicSystemFontOfSize:[UIFont systemFontSize]];
[subTitleItalic setFont:myItalicFont];

Add this android:screenOrientation="landscape" to your <activity> tag in the manifest for the specific activity that you want to be in landscape.

Edit:

To toggle the orientation from the Activity code, call setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) other parameters can be found in the Android docs for ActivityInfo.

1. Declare a variable.
2. Store the checked property for the radio button.
3. Have a if condition.

Lets assume

private string isChecked; 
private webElement e; 
isChecked =e.findElement(By.tagName("input")).getAttribute("checked");
if(isChecked=="true")
{

}
else 
{

}

Hope this answer will be help for you. Let me know, if have any clarification in CSharp Selenium web driver.

As noted in the comments, there are some things to try: gc.collect (@EdChum) may clear stuff, for example. At least from my experience, these things sometimes work and often don't.

There is one thing that always works, however, because it is done at the OS, not language, level.

Suppose you have a function that creates an intermediate huge DataFrame, and returns a smaller result (which might also be a DataFrame):

def huge_intermediate_calc(something):
    ...
    huge_df = pd.DataFrame(...)
    ...
    return some_aggregate

Then if you do something like

import multiprocessing

result = multiprocessing.Pool(1).map(huge_intermediate_calc, [something_])[0]

Then the function is executed at a different process. When that process completes, the OS retakes all the resources it used. There's really nothing Python, pandas, the garbage collector, could do to stop that.

Use this Layout in your xml file

<LinearLayout
  android:id="@+id/contacts_type"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:visibility="gone">
</LinearLayout>

Define your layout in .class file

 LinearLayout linearLayout = (LinearLayout) findViewById(R.id.contacts_type);

Now if you want to display this layout just write

 linearLayout.setVisibility(View.VISIBLE);

and if you want to hide layout just write

 linearLayout.setVisibility(View.INVISIBLE);

I made something simular, a RatingBar with individual rating icons, I'm using VectorDrawables for the rating icons but you could use any type of drawable

With Chart.js V2.0 you can to do the following:

websiteChart.config.data = some_new_data;
websiteChart.update();

If I understand correctly, what you want to do is divide by the maximum value in each column. You can do this easily using broadcasting.

Starting with your example array:

import numpy as np

x = np.array([[1000,  10,   0.5],
              [ 765,   5,  0.35],
              [ 800,   7,  0.09]])

x_normed = x / x.max(axis=0)

print(x_normed)
# [[ 1.     1.     1.   ]
#  [ 0.765  0.5    0.7  ]
#  [ 0.8    0.7    0.18 ]]

x.max(0) takes the maximum over the 0th dimension (i.e. rows). This gives you a vector of size (ncols,) containing the maximum value in each column. You can then divide x by this vector in order to normalize your values such that the maximum value in each column will be scaled to 1.

If x contains negative values you would need to subtract the minimum first:

x_normed = (x - x.min(0)) / x.ptp(0)

Here, x.ptp(0) returns the "peak-to-peak" (i.e. the range, max - min) along axis 0. This normalization also guarantees that the minimum value in each column will be 0.

I have found that within the socket.handshake.headers there is a forwarded for address which doesn't appear on my local machine. And I was able to get the remote address using:

socket.handshake.headers['x-forwarded-for']

This is in the server side and not client side.

What a shame that you can't get it to work over two lines! Would be awesome if the element was display block and had a height set to 2em or something, and when the text overflowed it would show an ellipsis!

For a single liner you can use:

.show-ellipsis {
    overflow: hidden;
    text-overflow: ellipsis;
    white-space: nowrap;
}

For multiple lines maybe you could use a Polyfill such as jQuery autoellipsis which is on github http://pvdspek.github.com/jquery.autoellipsis/

A text file does not have \0 at the end of lines. It has \n. \n is a character, not a string, so it must be enclosed in single quotes

if (c == '\n')

To add a file/folder to the project, a good way is:

First of all add your files to /path/to/your/project/my/added/files, and then run following commands:

svn cleanup  /path/to/your/project

svn add --force /path/to/your/project/*

svn cleanup  /path/to/your/project

svn commit /path/to/your/project  -m 'Adding a file'

I used cleanup to prevent any segmentation fault (core dumped), and now the SVN project is updated.

In my case I had a row of Ids, and it was neccessary to cast it to char, otherwise, the result was encoded into binary format :

SELECT CAST(GROUP_CONCAT(field SEPARATOR ',') AS CHAR) FROM table

It depends on the choice of hash function.

Many hash functions combine the various elements in the data by multiplying them with some factors modulo the power of two corresponding to the word size of the machine (that modulus is free by just letting the calculation overflow).

You don't want any common factor between a multiplier for a data element and the size of the hash table, because then it could happen that varying the data element doesn't spread the data over the whole table. If you choose a prime for the size of the table such a common factor is highly unlikely.

On the other hand, those factors are usually made up from odd primes, so you should also be safe using powers of two for your hash table (e.g. Eclipse uses 31 when it generates the Java hashCode() method).

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".

Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

this is my solution when we want to calculate a date given year, week number and day of the week.

int Year = 2014;
int Week = 48;
int DayOfWeek = 4;

DateTime FecIni = new DateTime(Year, 1, 1);
FecIni = FecIni.AddDays(7 * (Week - 1));
if ((int)FecIni.DayOfWeek > DayOfWeek)
{
    while ((int)FecIni.DayOfWeek != DayOfWeek) FecIni = FecIni.AddDays(-1);
}
else
{
    while ((int)FecIni.DayOfWeek != DayOfWeek) FecIni = FecIni.AddDays(1);
}

You can use below to find a particular trigger definition.

SHOW TRIGGERS LIKE '%trigger_name%'\G

or the below to show all the triggers in the database. It will work for MySQL 5.0 and above.

SHOW TRIGGERS\G

I'd suggest you do two things:

1. Use >> in your shell script to append contents to particular file. The filename can be fixed or using some pattern.
2. Setup a hourly cronjob to trigger the shell script

public static String loadTextFile(File f) {
    try {
        BufferedReader r = new BufferedReader(new FileReader(f));
        StringWriter w = new StringWriter();

        try {
            String line = reader.readLine();
            while (null != line) {
                w.append(line).append("\n");
                line = r.readLine();
            }

            return w.toString();
        } finally {
            r.close();
            w.close();
        }
    } catch (Exception ex) {
        ex.printStackTrace();

        return "";
    }
}

Not spectacular different than the answers already given, but more generic is :

sortArrayOfObjects = (arr, key) => {
    return arr.sort((a, b) => {
        return a[key] - b[key];
    });
};

sortArrayOfObjects(yourArray, "distance");

If you execute pip install virtualenvwrapper without sudo as a normal user pip will run but won't copy the files in the required locations because the lack of permissions.

I think that a fast answer for get the first character could be:

let firstCharacter = aString[aString.startIndex]

It's so much elegant and performance than:

let firstCharacter = Array(aString.characters).first

But.. if you want manipulate and do more operations with strings you could think create an extension..here is one extension with this approach, it's quite similar to that already posted here:

extension String {
var length : Int {
    return self.characters.count
}

subscript(integerIndex: Int) -> Character {
    let index = startIndex.advancedBy(integerIndex)
    return self[index]
}

subscript(integerRange: Range<Int>) -> String {
    let start = startIndex.advancedBy(integerRange.startIndex)
    let end = startIndex.advancedBy(integerRange.endIndex)
    let range = start..<end
    return self[range]
}

}

BUT IT'S A TERRIBLE IDEA!!

The extension below is horribly inefficient. Every time a string is accessed with an integer, an O(n) function to advance its starting index is run. Running a linear loop inside another linear loop means this for loop is accidentally O(n2) — as the length of the string increases, the time this loop takes increases quadratically.

Instead of doing that you could use the characters's string collection.

If you are referring to the npm module sleep, it notes in the readme that sleep will block execution. So you are right - it isn't what you want. Instead you want to use setTimeout which is non-blocking. Here is an example:

setTimeout(function() {
  console.log('hello world!');
}, 5000);

For anyone looking to do this using es7 async/await, this example should help:

const snooze = ms => new Promise(resolve => setTimeout(resolve, ms));

const example = async () => {
  console.log('About to snooze without halting the event loop...');
  await snooze(1000);
  console.log('done!');
};

example();

The difference between them is that they use different pins. Seriously, that's it. The reason they both exist is that RTS/CTS wasn't supposed to ever be a flow control mechanism, originally; it was for half-duplex modems to coordinate who was sending and who was receiving. RTS and CTS got misused for flow control so often that it became standard.

As per this paper Finding the Kth largest item in a list of n items the following algorithm will take O(n) time in worst case.

1. Divide the array in to n/5 lists of 5 elements each.
2. Find the median in each sub array of 5 elements.
3. Recursively ?nd the median of all the medians, lets call it M
4. Partition the array in to two sub array 1st sub-array contains the elements larger than M , lets say this sub-array is a1 , while other sub-array contains the elements smaller then M., lets call this sub-array a2.
5. If k <= |a1|, return selection (a1,k).
6. If k- 1 = |a1|, return M.
7. If k> |a1| + 1, return selection(a2,k -a1 - 1).

Analysis: As suggested in the original paper:

We use the median to partition the list into two halves(the first half, if k <= n/2 , and the second half otherwise). This algorithm takes time cn at the first level of recursion for some constant c, cn/2 at the next level (since we recurse in a list of size n/2), cn/4 at the third level, and so on. The total time taken is cn + cn/2 + cn/4 + .... = 2cn = o(n).

Why partition size is taken 5 and not 3?

As mentioned in original paper:

Dividing the list by 5 assures a worst-case split of 70 - 30. Atleast half of the medians greater than the median-of-medians, hence atleast half of the n/5 blocks have atleast 3 elements and this gives a 3n/10 split, which means the other partition is 7n/10 in worst case. That gives T(n) = T(n/5)+T(7n/10)+O(n). Since n/5+7n/10 < 1, the worst-case running time isO(n).

Now I have tried to implement the above algorithm as:

public static int findKthLargestUsingMedian(Integer[] array, int k) {
        // Step 1: Divide the list into n/5 lists of 5 element each.
        int noOfRequiredLists = (int) Math.ceil(array.length / 5.0);
        // Step 2: Find pivotal element aka median of medians.
        int medianOfMedian =  findMedianOfMedians(array, noOfRequiredLists);
        //Now we need two lists split using medianOfMedian as pivot. All elements in list listOne will be grater than medianOfMedian and listTwo will have elements lesser than medianOfMedian.
        List<Integer> listWithGreaterNumbers = new ArrayList<>(); // elements greater than medianOfMedian
        List<Integer> listWithSmallerNumbers = new ArrayList<>(); // elements less than medianOfMedian
        for (Integer element : array) {
            if (element < medianOfMedian) {
                listWithSmallerNumbers.add(element);
            } else if (element > medianOfMedian) {
                listWithGreaterNumbers.add(element);
            }
        }
        // Next step.
        if (k <= listWithGreaterNumbers.size()) return findKthLargestUsingMedian((Integer[]) listWithGreaterNumbers.toArray(new Integer[listWithGreaterNumbers.size()]), k);
        else if ((k - 1) == listWithGreaterNumbers.size()) return medianOfMedian;
        else if (k > (listWithGreaterNumbers.size() + 1)) return findKthLargestUsingMedian((Integer[]) listWithSmallerNumbers.toArray(new Integer[listWithSmallerNumbers.size()]), k-listWithGreaterNumbers.size()-1);
        return -1;
    }

    public static int findMedianOfMedians(Integer[] mainList, int noOfRequiredLists) {
        int[] medians = new int[noOfRequiredLists];
        for (int count = 0; count < noOfRequiredLists; count++) {
            int startOfPartialArray = 5 * count;
            int endOfPartialArray = startOfPartialArray + 5;
            Integer[] partialArray = Arrays.copyOfRange((Integer[]) mainList, startOfPartialArray, endOfPartialArray);
            // Step 2: Find median of each of these sublists.
            int medianIndex = partialArray.length/2;
            medians[count] = partialArray[medianIndex];
        }
        // Step 3: Find median of the medians.
        return medians[medians.length / 2];
    }

Just for sake of completion, another algorithm makes use of Priority Queue and takes time O(nlogn).

public static int findKthLargestUsingPriorityQueue(Integer[] nums, int k) {
        int p = 0;
        int numElements = nums.length;
        // create priority queue where all the elements of nums will be stored
        PriorityQueue<Integer> pq = new PriorityQueue<Integer>();

        // place all the elements of the array to this priority queue
        for (int n : nums) {
            pq.add(n);
        }

        // extract the kth largest element
        while (numElements - k + 1 > 0) {
            p = pq.poll();
            k++;
        }

        return p;
    }

Both of these algorithms can be tested as:

public static void main(String[] args) throws IOException {
        Integer[] numbers = new Integer[]{2, 3, 5, 4, 1, 12, 11, 13, 16, 7, 8, 6, 10, 9, 17, 15, 19, 20, 18, 23, 21, 22, 25, 24, 14};
        System.out.println(findKthLargestUsingMedian(numbers, 8));
        System.out.println(findKthLargestUsingPriorityQueue(numbers, 8));
    }

As expected output is: 18 18

Direct Closure serialisation is not allowed by PHP. But you can use powefull class like PHP Super Closure : https://github.com/jeremeamia/super_closure

This class is really simple to use and is bundled into the laravel framework for the queue manager.

From the github documentation :

$helloWorld = new SerializableClosure(function ($name = 'World') use ($greeting) {
    echo "{$greeting}, {$name}!\n";
});

$serialized = serialize($helloWorld);

Most modern desktop browsers such as Chrome, Mozilla and Internet Explorer support images encoded as data URL. But there are problems displaying data URLs in some mobile browsers: Android Stock Browser and Dolphin Browser won't display embedded JPEGs.

I reccomend you to use the following tools for online base64 encoding/decoding:

• Encode to Base64 format

• Decode from Base64 format

Check the "Format as Data URL" option to format as a Data URL.

My issue was with different version of DevExpress.

I successfully debug app through WiFi by following the official site's guide.

Note,

• WiFi debugging in Android 11+ is different from Android 10 and lower.
• Please update your adb, i.e. Android SDK Platform-tools to the latest version, otherwise you may miss some adb commands like adb pair.

Using below query you can remove leading and trailing whitespace in a MySQL.

UPDATE `table_name`
SET `col_name` = TRIM(`col_name`);

Follow Answer of @Arne. I Just fixing to Category function. put it in Category of UIImage.

-(UIImage*)cropImage:(CGRect)rect{

    UIGraphicsBeginImageContextWithOptions(rect.size, false, [self scale]);
    [self drawAtPoint:CGPointMake(-rect.origin.x, -rect.origin.y)];
    UIImage* cropped_image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return cropped_image;
}

I recently had this problem myself, and once I determined which AppPool was causing the problem, the only way to resolve the issue was remove that app pool completly and create a new one for the site to use.

Here's a revised version of your code which still works plus it illustrates how to raise a ValueError the way you want. By-the-way, I think find_last(), find_last_index(), or something simlar would be a more descriptive name for this function. Adding to the possible confusion is the fact that Python already has a container object method named __contains__() that does something a little different, membership-testing-wise.

def contains(char_string, char):
    largest_index = -1
    for i, ch in enumerate(char_string):
        if ch == char:
            largest_index = i
    if largest_index > -1:  # any found?
        return largest_index  # return index of last one
    else:
        raise ValueError('could not find {!r} in {!r}'.format(char, char_string))

print(contains('mississippi', 's'))  # -> 6
print(contains('bababa', 'k'))  # ->

Traceback (most recent call last):
  File "how-to-raise-a-valueerror.py", line 15, in <module>
    print(contains('bababa', 'k'))
  File "how-to-raise-a-valueerror.py", line 12, in contains
    raise ValueError('could not find {} in {}'.format(char, char_string))
ValueError: could not find 'k' in 'bababa'

Update — A substantially simpler way

Wow! Here's a much more concise version—essentially a one-liner—that is also likely faster because it reverses (via [::-1]) the string before doing a forward search through it for the first matching character and it does so using the fast built-in string index() method. With respect to your actual question, a nice little bonus convenience that comes with using index() is that it already raises a ValueError when the character substring isn't found, so nothing additional is required to make that happen.

Here it is along with a quick unit test:

def contains(char_string, char):
    #  Ending - 1 adjusts returned index to account for searching in reverse.
    return len(char_string) - char_string[::-1].index(char) - 1

print(contains('mississippi', 's'))  # -> 6
print(contains('bababa', 'k'))  # ->

Traceback (most recent call last):
  File "better-way-to-raise-a-valueerror.py", line 9, in <module>
    print(contains('bababa', 'k'))
  File "better-way-to-raise-a-valueerror", line 6, in contains
    return len(char_string) - char_string[::-1].index(char) - 1
ValueError: substring not found

There is a way to retrieve the password by using Brute-Force attack, have a look at the following tool from codeproject Retrieve SQL Server Password

How to use the tool to retrieve the password

To Retrieve the password of SQL Server user,run the following query in SQL Query Analyzer

"Select Password from SysxLogins Where Name = 'XXXX'" Where XXXX is the user

name for which you want to retrieve password.Copy the password field (Hashed Code) and

paste here (in Hashed code Field) and click on start button to retrieve

I checked the tool on SQLServer 2000 and it's working fine.

Try <TableRow android:gravity="center_horizontal"> This will center the inner LinearLayout within the tablerow.

First install the JDK1.8 set to Path Open Eclipse and Oper Eclipse Market Place option. Search for jdk 1.8 for kepler Install the required plugin. Restart the eclipse. Change compiler level to 1.8 from preferences. If still there is an error then click on the file and change the compiler setting explicitly to Jdk 1.8

A more modern version of kaiido's answer using fetch would be:

function toObjectUrl(url) {
  return fetch(url)
      .then((response)=> {
        return response.blob();
      })
      .then(blob=> {
        return URL.createObjectURL(blob);
      });
}

https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch

Edit: As pointed out in the comments this will return an object url which points to a file in your local system instead of an actual DataURL so depending on your use case this might not be what you need.

You can look at the following answer to use fetch and an actual dataURL: https://stackoverflow.com/a/50463054/599602

This is done using the REPLACE function

To strip out "somestring" from "SomeColumn" in "SomeTable" in the SELECT query:

SELECT REPLACE([SomeColumn],'somestring','') AS [SomeColumn]  FROM [SomeTable]

To update the table and strip out "somestring" from "SomeColumn" in "SomeTable"

UPDATE [SomeTable] SET [SomeColumn] = REPLACE([SomeColumn], 'somestring', '')

In SQL, NULL = NULL is false, you usually have to use IS NULL:

SELECT CASE WHEN MAX(id) IS NULL THEN 0 ELSE (MAX(id) + 1) END FROM words

But, if you want the number of rows, you should just use count(id) since your solution will give 10 if your rows are (0,1,3,5,9) where it should give 5.

If you can guarantee you will always ids from 0 to N, max(id)+1 may be faster depending on the index implementation (it may be faster to traverse the right side of a balanced tree rather than traversing the whole tree, counting.

But that's very implementation-specific and I would advise against relying on it, not least because it locks your performance to a specific DBMS.

One thing that you could do would be to modify the catalina.sh (Unix based) or the catalina.bat (windows based).

Within each of the scripts you can set certain variables which only processes created under the shell will inherit. So for catalina.sh, use the following line:

export JAVA_HOME="intented java home"

And for windows use

set JAVA_HOME="intented java home"
