Lets say you have span1 as <span id='span1'>my text</span>
text change events can be captured with:

$(document).ready(function(){
    $("#span1").on('DOMSubtreeModified',function(){
         // text change handler
     });

 });
 

a = 0.000006;
b = 6;
c = a/b;

textbox.Text = c.ToString("0.000000");

As you requested:

textbox.Text = c.ToString("0.######");

This will only display out to the 6th decimal place if there are 6 decimals to display.

for_example, you have anyFile.php, and there is written $any_variable='hi Frank';

to change that variable to hi Jack, use like the following code:

<?php
$content = file_get_contents('anyFile.php'); 

$new_content = preg_replace('/\$any_variable=\"(.*?)\";/', '$any_variable="hi Jack";', $content);

file_put_contents('anyFile.php', $new_content);
?>

@echo off
@color 0A

echo Deleting logs

rmdir /S/Q c:\log\

ping 1.1.1.1 -n 5 -w 1000 > nul

echo Adding log folder back

md c:\log\

You was on the right track. Just add code to add the folder which is deleted back again.

If this can't be wrapped with generics (@Martijn's answer) it's better to pass it without casting to avoid redundant list iteration (checking the first element's type guarantees nothing). We can cast each element in the piece of code where we iterate the list.

Object attVal = jsonMap.get("attName");
List<Object> ls = new ArrayList<>();
if (attVal instanceof List) {
    ls.addAll((List) attVal);
} else {
    ls.add(attVal);
}

// far, far away ;)
for (Object item : ls) {
    if (item instanceof String) {
        System.out.println(item);
    } else {
        throw new RuntimeException("Wrong class ("+item .getClass()+") of "+item );
    }
}

from pyspark.sql.functions import udf
from pyspark.sql.types import *
func_name = udf(
    lambda val: val, # do sth to val
    StringType()
)
df.withColumn('new_col', func_name(df.old_col))

Using code to parse ps aux for linux and tasklist for windows are your best options, until something more general comes along.

For windows, you can reference: http://www.rgagnon.com/javadetails/java-0593.html

Linux can pipe the results of ps aux through grep too, which would make processing/searching quick and easy. I'm sure you can find something similar for windows too.

Note: This code was originally included in the question above. In the interests of keeping the question short and focused, I've moved it to this Community Wiki answer.

I found this code kicking around and it appears to work fine for getting a random number and then using the seed afterward but I'm not quite sure how the logic works (e.g. where the 2345678901, 48271 & 2147483647 numbers came from).

function nextRandomNumber(){
  var hi = this.seed / this.Q;
  var lo = this.seed % this.Q;
  var test = this.A * lo - this.R * hi;
  if(test > 0){
    this.seed = test;
  } else {
    this.seed = test + this.M;
  }
  return (this.seed * this.oneOverM);
}

function RandomNumberGenerator(){
  var d = new Date();
  this.seed = 2345678901 + (d.getSeconds() * 0xFFFFFF) + (d.getMinutes() * 0xFFFF);
  this.A = 48271;
  this.M = 2147483647;
  this.Q = this.M / this.A;
  this.R = this.M % this.A;
  this.oneOverM = 1.0 / this.M;
  this.next = nextRandomNumber;
  return this;
}

function createRandomNumber(Min, Max){
  var rand = new RandomNumberGenerator();
  return Math.round((Max-Min) * rand.next() + Min);
}

//Thus I can now do:
var letters = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'];
var numbers = ['1','2','3','4','5','6','7','8','9','10'];
var colors = ['red','orange','yellow','green','blue','indigo','violet'];
var first = letters[createRandomNumber(0, letters.length)];
var second = numbers[createRandomNumber(0, numbers.length)];
var third = colors[createRandomNumber(0, colors.length)];

alert("Today's show was brought to you by the letter: " + first + ", the number " + second + ", and the color " + third + "!");

/*
  If I could pass my own seed into the createRandomNumber(min, max, seed);
  function then I could reproduce a random output later if desired.
*/

Canvas would be a great way to do this, as @pst said above. Check out this answer for a good example:

getPixel from HTML Canvas?

Some code that would serve you specifically as well:

var imgd = context.getImageData(x, y, width, height);
var pix = imgd.data;

for (var i = 0, n = pix.length; i < n; i += 4) {
  console.log pix[i+3]
}

This will go row by row, so you'd need to convert that into an x,y and either convert the for loop to a direct check or run a conditional inside.

Reading your question again, it looks like you want to be able to get the point that the person clicks on. This can be done pretty easily with jquery's click event. Just run the above code inside a click handler as such:

$('el').click(function(e){
   console.log(e.clientX, e.clientY)
}

Those should grab your x and y values.

glob2rx() converts a pattern including a wildcard into the equivalent regular expression. You then need to pass this regular expression onto one of R's pattern matching tools.

If you want to match "blue*" where * has the usual wildcard, not regular expression, meaning we use glob2rx() to convert the wildcard pattern into a useful regular expression:

> glob2rx("blue*")
[1] "^blue"

The returned object is a regular expression.

Given your data:

x <- c('red','blue1','blue2', 'red2')

we can pattern match using grep() or similar tools:

> grx <- glob2rx("blue*")
> grep(grx, x)
[1] 2 3
> grep(grx, x, value = TRUE)
[1] "blue1" "blue2"
> grepl(grx, x)
[1] FALSE  TRUE  TRUE FALSE

As for the selecting rows problem you posted

> a <- data.frame(x =  c('red','blue1','blue2', 'red2'))
> with(a, a[grepl(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
> with(a, a[grep(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2

or via subset():

> with(a, subset(a, subset = grepl(grx, x)))
      x
2 blue1
3 blue2

Hope that explains what grob2rx() does and how to use it?

By using heap object reference if we want to get corresponding string constant pool object reference, then we should go for intern()

String s1 = new String("Rakesh");
String s2 = s1.intern();
String s3 = "Rakesh";

System.out.println(s1 == s2); // false
System.out.println(s2 == s3); // true

Pictorial View

Step 1: Object with data 'Rakesh' get created in heap and string constant pool. Also s1 is always pointing to heap object.

Step 2: By using heap object reference s1, we are trying to get corresponding string constant pool object referenc s2, using intern()

Step 3: Intentionally creating a object with data 'Rakesh' in string constant pool, referenced by name s3

As "==" operator meant for reference comparison.

Getting false for s1==s2

Getting true for s2==s3

Hope this help!!

try to use px

.modal .modal-dialog {

}

just change the size.

uint16_t is unsigned 16-bit integer.

unsigned short int is unsigned short integer, but the size is implementation dependent. The standard only says it's at least 16-bit (i.e, minimum value of UINT_MAX is 65535). In practice, it usually is 16-bit, but you can't take that as guaranteed.

Note:

1. If you want a portable unsigned 16-bit integer, use uint16_t.
2. inttypes.h and stdint.h are both introduced in C99. If you are using C89, define your own type.
3. uint16_t may not be provided in certain implementation(See reference below), but unsigned short int is always available.

Reference: C11(ISO/IEC 9899:201x) §7.20 Integer types

For each type described herein that the implementation provides) shall declare that typedef name and define the associated macros. Conversely, for each type described herein that the implementation does not provide, shall not declare that typedef name nor shall it define the associated macros. An implementation shall provide those types described as ‘‘required’’, but need not provide any of the others (described as ‘optional’’).

The same error is produced in MariaDB (10.1.36-MariaDB) by using the combination of parenthesis and the COLLATE statement. My SQL was different, the error was the same, I had:

SELECT *
FROM table1
WHERE (field = 'STRING') COLLATE utf8_bin;

Omitting the parenthesis was solving it for me.

SELECT *
FROM table1
WHERE field = 'STRING' COLLATE utf8_bin;

You might want to consider also checking if a value is finite via Double.isFinite(value). Since Java 8 there is a new method in Double class where you can check at once if a value is not NaN and infinity.

/**
 * Returns {@code true} if the argument is a finite floating-point
 * value; returns {@code false} otherwise (for NaN and infinity
 * arguments).
 *
 * @param d the {@code double} value to be tested
 * @return {@code true} if the argument is a finite
 * floating-point value, {@code false} otherwise.
 * @since 1.8
 */
public static boolean isFinite(double d)

I tried @JsonDetect and

@JsonIgnoreProperties(value = { "handler", "hibernateLazyInitializer" })

Neither of them worked for me. Using a third-party module seemed like a lot of work to me. So I just tried making a get call on any property of the lazy object before passing to jackson for serlization. The working code snippet looked something like this :

@RequestMapping(value = "/authenticate", produces = "application/json; charset=utf-8")
    @ResponseBody
    @Transactional
    public Account authenticate(Principal principal) {
        UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = (UsernamePasswordAuthenticationToken) principal;
        LoggedInUserDetails loggedInUserDetails = (LoggedInUserDetails) usernamePasswordAuthenticationToken.getPrincipal();
        User user = userRepository.findOne(loggedInUserDetails.getUserId());
        Account account = user.getAccount();
        account.getFullName();      //Since, account is lazy giving it directly to jackson for serlization didn't worked & hence, this quick-fix.
        return account;
    }

Two methods:

1. Convert to PNG and make the original image 0.2 opacity
2. (Better method) have a <div> that is position: absolute; before #main and the same height as #main, then apply the background-image and opacity: 0.2; filter: alpha(opacity=20);.

If your rename doesn't support -N, you can do something like this:

ls -1 --color=never -c | xargs rename -n 's/.*/our $i; sprintf("%04d.jpg", $i++)/e'

Edit To start with a given number, you can use the (somewhat ugly-looking) code below, just replace 123 with the number you want:

ls -1 --color=never  -c | xargs rename -n 's/.*/our $i; if(!$i) { $i=123; } sprintf("%04d.jpg", $i++)/e'

This lists files in order by creation time (newest first, add -r to ls to reverse sort), then sends this list of files to rename. Rename uses perl code in the regex to format and increment counter.

However, if you're dealing with JPEG images with EXIF information, I'd recommend exiftool

This is from the exiftool documentation, under "Renaming Examples"

   exiftool '-FileName<CreateDate' -d %Y%m%d_%H%M%S%%-c.%%e dir

   Rename all images in "dir" according to the "CreateDate" date and time, adding a copy number with leading '-' if the file already exists ("%-c"), and
   preserving the original file extension (%e).  Note the extra '%' necessary to escape the filename codes (%c and %e) in the date format string.

If you are using Facebook inside app check for provider tag inside AndroidManifest file and check your project Id is correct for android:authorities

<provider android:name="com.facebook.FacebookContentProvider" android:authorities="com.facebook.app.FacebookContentProvider112623702612345" android:exported="true" />

If you try to run

sudo -H pip3 install --upgrade pip3 

you will get the following error:

WARNING: You are using pip version 19.2.3, however version 21.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

but if you upgrade using the suggested command:

pip install --upgrade pip

then, the legacy pip will be upgraded, so what I did is the following:

which pip3

and I located my pip3 installation (just in case the following command wouldn't upgrade the legacy pip. Then i changed to that directory and upgraded pip3 using the following commands: (your directory could be different)

cd /Library/Frameworks/Python.framework/Versions/3.8/bin
sudo -H pip3 install --upgrade pip

after this:

pip --version

will still show the legacy version, while

pip3 --version

will show pip 21.0.1

In my case it was the problem of building the extension, I was pointing at an extension src (with manifest and everything) but without a build.

If you run into this scenario run npm i then npm build

You typically restore purchases with this code:

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

It will reinvoke -paymentQueue:updatedTransactions on the observer(s) for the purchased items. This is useful for users who reinstall the app after deletion or install it on a different device.

Not all types of In-App purchases can be restored.

You can assign "button" to role attribute of any html tag/element to make pointer over it. i.e

<html-element role="button" />

Say the table is user(id, user_name, user_email).

You can use this query:

INSERT INTO user (SELECT NULL,user_name, user_email FROM user WHERE id = 1)

Even i was facing the same problem ,but solved it by

conda install -c conda-forge pysoundfile

while importing it

import soundfile 

For Decryption:

     def decrypt(my_key=KEY, my_iv=IV, encryptText=encrypttext):

        key = binascii.unhexlify(my_key)
        iv = binascii.unhexlify(my_iv)
        encryptor = AES.new(key, AES.MODE_CBC, iv, segment_size=128)  # Initialize encryptor
        result = encryptor.decrypt(binascii.a2b_hex(encryptText))
        padder = PKCS7Padder()
        decryptText=padder.decode(result)  

           return {

          "decryptedTest": decryptText
}

Is it possible for you to use sudo apt-get install python-seaborn instead? Basically tar.gz is just a zip file containing a setup, so what you want to do is to unzip it, cd to the place where it is downloaded and use gunzip -c seaborn-0.7.0.tar.gz | tar xf - for linux. Change dictionary into the new seaborn unzipped file and execute python setup.py install

I think the best way to do this is separate the 'recognition' from the functionality:

struct stringcase { char* string; void (*func)(void); };

void funcB1();
void funcAzA();

stringcase cases [] = 
{ { "B1", funcB1 }
, { "AzA", funcAzA }
};

void myswitch( char* token ) {
  for( stringcases* pCase = cases
     ; pCase != cases + sizeof( cases ) / sizeof( cases[0] )
     ; pCase++ )
  {
    if( 0 == strcmp( pCase->string, token ) ) {
       (*pCase->func)();
       break;
    }
  }

}

We use Akka in several projects at work, the most interesting of which is related to vehicle crash repair. Primarily in the UK but now expanding to the US, Asia, Australasia and Europe. We use actors to ensure that crash repair information is provided realtime to enable the safe and cost effective repair of vehicles.

The question with Akka is really more 'what can't you do with Akka'. Its ability to integrate with powerful frameworks, its powerful abstraction and all of the fault tolerance aspects make it a very comprehensive toolkit.

I had a similar issue. The content of the child element was supposed to stay in the parent element while the background had to extend the full viewport width.

I resolved this issue by making the child element position: relative and adding a pseudo element (:before) to it with position: absolute; top: 0; bottom: 0; width: 4000px; left: -1000px;. The pseudo element stays behind the actual child as a pseudo background element. This works in all browsers (even IE8+ and Safari 6+ - don't have the possibility to test older versions).

SpringBoot developers recommend to locate your main application class in a root package above other classes. Using a root package also allows the @ComponentScan annotation to be used without needing to specify a basePackage attribute. Detailed info But be sure that the custom root package exists.

ContentDescription needed for the Android accessibility. Particularly for the screen reader feature. If you don't support Android accessibility you can ignore it with setup Lint.

So just create lint.xml.

<?xml version="1.0" encoding="UTF-8"?>
<lint>

    <issue id="ContentDescription" severity="ignore" />

</lint>

And put it to the app folder.

The modulo operator is % (percent sign). To test for evenness or generally do modulo for a power of 2, you can also use & (the and operator) like isEven = !( a & 1 ).

You can try the following line of code

$result = $data1." ".$data2;

Try this: (For Preview)

<script type="text/javascript">
    function readURL(input) {
        if (input.files && input.files[0]) {
            var reader = new FileReader();

            reader.onload = function (e) {
                $('#blah').attr('src', e.target.result);
            }

            reader.readAsDataURL(input.files[0]);
        }
    }
</script>

<body>
    <form id="form1" runat="server">
        <input type="file" onchange="readURL(this);" />
        <img id="blah" src="#" alt="your image" />
    </form>
</body>

To Answer your question: now AWS make cloning real easy see Launch instance from your Existing Instance

1. On the EC2 Instances page, select the instance you want to use
2. Choose Actions, and then Launch More Like This.
3. Review & Launch

This will take the existing instance as a Template for the new once.

or you can also take a snapshot of the existing volume and use the snapshot with the AMI (existing one) which you ping during your instance launch

Don't double click Project.xcodeproj to start your xcode project. Instead, close your project and open the xcworkspace.

Shift-Alt-J is a useful keyboard shortcut in Eclipse for creating Javadoc comment templates.

Invoking the shortcut on a class, method or field declaration will create a Javadoc template:

public int doAction(int i) {
    return i;
}

Pressing Shift-Alt-J on the method declaration gives:

/**
 * @param i
 * @return
 */
public int doAction(int i) {
    return i;
}

Another code sample to convert a real/float to an integer using variables. "vel" is a real/float number and converted to the next highest INTEGER, "newvel".

import arcpy.math, os, sys, arcpy.da
.
.
with arcpy.da.SearchCursor(densifybkp,[floseg,vel,Length]) as cursor:
 for row in cursor:
    curvel = float(row[1])
    newvel = int(math.ceil(curvel))

If you want to change tabs to spaces in a lot of files, but don't want to open them individually, I have found that it works equally as well to just use the Find and Replace option from the left-most tools bar.

In the first box (Find), copy and paste a tab from the source code.

In the second box (Replace), enter the number of spaces that you wish to use (i.e. 2 or 4).

If you press the ... button, you can specify directories to include or ignore (i.e. src/Data/Json).

Finally, inspect the result preview and press Replace All. All files in the workspace may be affected.

Simply type in the console :

$ git reset HEAD~

This command discards all local commits ahead of the remote HEAD

Maybe this can help you also. It's from the website:

http://nathanael.hevenet.com/android-dev-changing-the-title-bar-background/

First things first you need to have a custom theme declared for your application (or activity, depending on your needs). Something like…

<!-- Somewhere in AndroidManifest.xml -->
<application ... android:theme="@style/ThemeSelector">

Then, declare your custom theme for two cases, API versions with and without the Holo Themes. For the old themes we’ll customize the windowTitleBackgroundStyle attribute, and for the newer ones the ActionBarStyle.

<!-- res/values/styles.xml -->
<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="ThemeSelector" parent="android:Theme.Light">
        <item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>
    </style>

    <style name="WindowTitleBackground">     
        <item name="android:background">@color/title_background</item>
    </style>

</resources>

<!-- res/values-v11/styles.xml -->
<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="ThemeSelector" parent="android:Theme.Holo.Light">
        <item name="android:actionBarStyle">@style/ActionBar</item>
    </style>

    <style name="ActionBar" parent="android:style/Widget.Holo.ActionBar">     
        <item name="android:background">@color/title_background</item>
    </style>

</resources>

That’s it!

TL;DR

In the first case with set encoding=utf-8, you'll change the output encoding that is shown in the terminal.

In the second case with set fileencoding=utf-8, you'll change the output encoding of the file that is written.

As stated by @Dennis, you can set them both in your ~/.vimrc if you always want to work in utf-8.

More details

From the wiki of VIM about working with unicode

"encoding sets how vim shall represent characters internally. Utf-8 is necessary for most flavors of Unicode."

"fileencoding sets the encoding for a particular file (local to buffer); :setglobal sets the default value. An empty value can also be used: it defaults to same as 'encoding'. Or you may want to set one of the ucs encodings, It might make the same disk file bigger or smaller depending on your particular mix of characters. Also, IIUC, utf-8 is always big-endian (high bit first) while ucs can be big-endian or little-endian, so if you use it, you will probably need to set 'bomb" (see below)."

var exec = require('child_process').exec;
exec('pwd', function callback(error, stdout, stderr){
    // result
});

This is an old question, but no one responded to the question regarding centering text in a terminal.

/**
 * Centers a string of text in a terminal window
 *
 * @param string $text The text to center
 * @param string $pad_string If set, the string to pad with (eg. '=' for a nice header)
 *
 * @return string The padded result, ready to echo
 */
function center($text, $pad_string = ' ') {
    $window_size = (int) `tput cols`;
    return str_pad($text, $window_size, $pad_string, STR_PAD_BOTH)."\n";
}

echo center('foo');
echo center('bar baz', '=');

Take a look at this article. You do not use the public DNS but rather the form

ssh -i your.pem [email protected]

where the name is visible on your AMI panel

DECLARE @MyFloat [float]

SET @MyFloat = 1000109360.050

SELECT REPLACE (RTRIM (REPLACE (REPLACE (RTRIM ((REPLACE (CAST (CAST (@MyFloat AS DECIMAL (38 ,18 )) AS VARCHAR( max)), '0' , ' '))), ' ' , '0'), '.', ' ')), ' ','.')

InnoDB allows you to add a new foreign key constraint to a table by using ALTER TABLE:

ALTER TABLE tbl_name
    ADD [CONSTRAINT [symbol]] FOREIGN KEY
    [index_name] (index_col_name, ...)
    REFERENCES tbl_name (index_col_name,...)
    [ON DELETE reference_option]
    [ON UPDATE reference_option]

On the other hand, if MyISAM has advantages over InnoDB in your context, why would you want to create foreign key constraints at all. You can handle this on the model level of your application. Just make sure the columns which you want to use as foreign keys are indexed!

The vertical-align css attribute doesn't do what you expect unfortunately. This article explains 2 ways to vertically align an element using css.

When using java 8, you may take advantage of stream API and simplify code to

return (YourEntityClass) entityManager.createQuery()
....
.getResultList()
.stream().findFirst();

That will give you java.util.Optional

If you prefer null instead, all you need is

 ...
.getResultList()
.stream().findFirst().orElse(null);

There is a lateinit improvement in Kotlin 1.2 that allows to check the initialization state of lateinit variable directly:

lateinit var file: File    

if (this::file.isInitialized) { ... }

See the annoucement on JetBrains blog or the KEEP proposal.

UPDATE: Kotlin 1.2 has been released. You can find lateinit enhancements here:

• Checking whether a lateinit var is initialized
• Lateinit top-level properties and local variables

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

You could compile and link in one command:

gcc file1.c file2.c -o myprogram

And run with:

./myprogram

But to answer the question as asked, simply pass the object files to gcc:

gcc file1.o file2.o -o myprogram

Accepts a dict as argument and returns a dataframe with the keys of the dict as index and values as a column.

def dict_to_df(d):
    df=pd.DataFrame(d.items())
    df.set_index(0, inplace=True)
    return df

Create xml file like edit_text_design.xml and save it to your drawable folder

</layer-list>

your Edit Text Should contain it as Background :

add android:background="@drawable/edit_text_design" to all of your EditText's

and your above EditText should now look like this:

      <EditText
        android:id="@+id/name_edit_text"
        android:background="@drawable/edit_text_design"
        android:layout_width="wrap_content"

        android:layout_below="@+id/profile_image_view_layout"
        android:layout_centerHorizontal="true"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginTop="20dp"
        android:ems="15"
        android:hint="@string/name_field"
        android:inputType="text" />

The swift way to do it:

UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .any, barMetrics: .default)
UINavigationBar.appearance().shadowImage = UIImage()

Service references deal with endpoints and bindings, which are completely configurable. They let you point your client proxy to a WCF via any transport protocol (HTTP, TCP, Shared Memory, etc)

They are designed to work with WCF.

If you use a WebProxy, you are pretty much binding yourself to using WCF over HTTP

There are apparently different levels of authentication. Most articles I read tell you to set the MaxAllowedZone to '1' which means that local machine zone and intranet zone are allowed but '4' allows access for 'all' zones.

This is how my registry looks (I wasn't sure it would work with the wild cards but it seems to work for me):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000004

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"UrlAllowList"="\\\\<network_path_root>;\\\\<network_path_root>\*;\\ies-inc.local;http://www.*;http://*;https://www.*;https://*;"

As an additional note, weirdly the "UrlAllowList" key was required to make this work on another PC but not my test one. It's probably not required at all but when I added it, it fixed the problem. The user may have not closed the original file or something like that. So just a consideration. I suggest try the least and test it, then add if needed. Once you confirm, you can deploy if needed. Good Luck!

Edit: P.S. Another method that worked was mapping the path to the network locally by using mklink /d (symbolic linking in Windows 7 or newer) but mapping a network drive letter (Z: for testing) did not work. Just food for thought and I did not have to 'Unblock' any files. Also the accepted 'Solution' did not resolve the issue for me.

If you're running a jar file with java -jar, the -classpath argument is ignored. You need to set the classpath in the manifest file of your jar, like so:

Class-Path: jar1-name jar2-name directory-name/jar3-name

See the Java tutorials: Adding Classes to the JAR File's Classpath.

Edit: I see you already tried setting the class path in the manifest, but are you sure you used the correct syntax? If you skip the ':' after "Class-Path" like you showed, it would not work.

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

Override windowClosing Method.

public void windowClosing(WindowEvent e)

It is invoked when a window is in the process of being closed. The close operation can be overridden at this point.

I got it working by adding to ~/.profile. Somehow after updating to El Capitan beta, it didnt work even though JAVA_HOME was defined in .bash_profile.

If there are any El Capitan beta users, try adding to .profile

More generally, you can also convert the new data into an array and use something like concat:

var newData = this.state.data.concat([data]);  
this.setState({data: newData})

This pattern is actually used in Facebook's ToDo demo app (see the section "An Application") at https://facebook.github.io/react/.

$sql="DELETE FROM basic_tbl,education_tbl, personal_tbl ,address_tbl,department_tbl USING basic_tbl,education_tbl, personal_tbl ,address_tbl,department_tbl WHERE b_id=e_id=p_id=a_id=d_id='".$id."' "; $rs=mysqli_query($con,$sql);

This error can also surface if your MSI installer failed to actually deploy the file.

In my case this happened because I converted the .aspx files to .cshtml files and visual studio thought these were brand new files and set the build action to none instead of content.

(function($){
    $.fn.displayChange = function(fn){
        $this = $(this);
        var state = {};
        state.old = $this.css('display');
        var intervalID = setInterval(function(){
            if( $this.css('display') != state.old ){
                state.change = $this.css('display');
                fn(state);
                state.old = $this.css('display');
            }
        }, 100);        
    }

    $(function(){
        var tag = $('#content');
        tag.displayChange(function(obj){
            console.log(obj);
        });  
    })   
})(jQuery);

On SuSE linux, you can use the following command to install 'texinfo':

sudo zypper install texinfo

On my system, it shows it is downloading about 1000 MiB, so make sure you have enough free space.

you can do it short like this:

matrix = [["A, B, C, D, E"]*5]
print(matrix)


[['A, B, C, D, E', 'A, B, C, D, E', 'A, B, C, D, E', 'A, B, C, D, E', 'A, B, C, D, E']]

For WHM Panel

Menu > Server Configuration > Terminal:

yum install libssh2-devel -y

1. PHP PECL Manage Click
2. ssh2 Install Now Click

Are you sure you wish to restart this service?

Yes

ssh2_connect() Work!

If the WAMP icon is Orange then one of the services has not started.

In your case it looks like MySQL has not started as you are getting the message that indicates there is no server running and therefore listening for requests.

Look at the mysql log and if that tells you nothing look at the Windows event log, in the Windows -> Applications section. Error messages in there are pretty good at identifying the cause of MySQL failing to start.

Sometimes this is caused by a my.ini file from another install being picked up by WAMPServers MySQL, normally in the \windows or \windows\system32 folders. Do a search for 'my.ini' and 'my.cnf' and if you find one of these anywhere outside of the \wamp.... folder structure then delete it, or at least rename it so it wont be found. Then restart the MySQL service.

Writing from phone, but curvycorners is really good, since it adds it's own borders only if browser doesn't support it by default. In other words, browsers which already support some CSS3 will use their own system to provide corners.

You need to tell Eclipse which JDK/JRE's you have installed and where they are located.

This is somewhat burried in the Eclipse preferences: In the Window-Menu select "Preferences". In the Preferences Tree, open the Node "Java" and select "Installed JRE's". Then click on the "Add"-Button in the Panel and select "Standard VM", "Next" and for "JRE Home" click on the "Directory"-Button and select the top level folder of the JDK you want to add.

Its easier than the description may make it look.

Flow allows interface specification, without having to convert your whole code base to TypeScript.

Interfaces are a way of breaking dependencies, while stepping cautiously within existing code.

It uses HTML DOM Elements, but not jQuery selector. It can be used like:

var height = document.body.scrollHeight;

A library that has all the functionality that it seems you're looking for is humanize. humanize.naturalsize() seems to do everything you're looking for.

you can use String format to include variables within strings

i use this code to include 2 variable in string:

String myString = String.format("this is my string %s %2d", variable1Name, variable2Name);

To detect Internet Explorer 10|11 you can use this little script immediatelly after body tag:

In my case i use jQuery library loaded in head.

<!DOCTYPE HTML>
<html>
<head>
    <script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
</head>
<body>
    <script>if (navigator.appVersion.indexOf('Trident/') != -1) $("body").addClass("ie10");</script>
</body>
</html>

If you want to install dependencies from a requirements file within a CI server or alike, you can do this:

git config --global credential.helper 'cache'
echo "protocol=https
host=example.com
username=${GIT_USER}
password=${GIT_PASS}
" | git credential approve
pip install -r requirements.txt

In my case, I used GIT_USER=gitlab-ci-token and GIT_PASS=${CI_JOB_TOKEN}.

This method has a clear advantage. You have a single requirements file which contains all of your dependencies.

An alternative solution:

div[class|='tocolor'] will match for values of the "class" attribute that begin with "tocolor-", including "tocolor-1", "tocolor-2", etc.

Beware that this won't match

<div class="foo tocolor-">

Reference: https://www.w3.org/TR/css3-selectors/#attribute-representation

[att|=val]

Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D)

This worked for me best

To answer the original question: yes, you can access the index value of a row in apply(). It is available under the key name and requires that you specify axis=1 (because the lambda processes the columns of a row and not the rows of a column).

Working example (pandas 0.23.4):

>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
   b  c
a      
1  2  3
4  5  6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
   b  c  index_x10
a                 
1  2  3         10
4  5  6         40

Is it possible the root password is not what you think it is? Have you checked the file /root/.mysql_secret for the password? That is the default location for the automated root password that is generated from starting from version 5.7.

cat /root/.mysql_secret

There is no difference between using OR ; i.e. it is a convention used by C++ programmers. I myself prefer as it more clearly describes it use; i.e. defining a template with a specific type :)

Note: There is one exception where you do have to use class (and not typename) when declaring a template template parameter:

template <template class T> class C { }; // valid!

template <template typename T> class C { }; // invalid!

In most cases, you will not be defining a nested template definition, so either definition will work -- just be consistent in your use...

You can change action bar color on this way:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/green_action_bar</item>
</style>

Thats all you need for changing action bar color.

Plus if you want to change the status bar color just add the line:

 <item name="android:colorPrimaryDark">@color/green_dark_action_bar</item>

Here is a screenshot taken from developer android site to make it more clear, and here is a link to read more about customizing the color palete

If I'm reading your question right, you want to run a script in the post build actions part of the build.

I myself use PostBuildScript Plugin for running git clean -fxd after the build has archived artifacts and published test results. My Jenkins slaves have SSD disks, so I do not have the room keep generated files in the workspace.

I recommend you to do this by simply go to your .git folder, then open config file. In the file paste your user info:

[user]
    name = Your-Name
    email = Your-email

This should be it.

I would have done it like this. Short and sweet :)

Sub test()
Dim rngToSearch As Range
Dim FirstBlankCell As Range
Dim firstEmptyRow As Long

Set rngToSearch = Sheet1.Range("A:A")
    'Check first cell isn't empty
    If IsEmpty(rngToSearch.Cells(1, 1)) Then
        firstEmptyRow = rngToSearch.Cells(1, 1).Row
    Else
        Set FirstBlankCell = rngToSearch.FindNext(After:=rngToSearch.Cells(1, 1))
        If Not FirstBlankCell Is Nothing Then
            firstEmptyRow = FirstBlankCell.Row
        Else
            'no empty cell in range searched
        End If
    End If
End Sub

Updated to check if first row is empty.

Edit: Update to include check if entire row is empty

Option Explicit

Sub test()
Dim rngToSearch As Range
Dim firstblankrownumber As Long

    Set rngToSearch = Sheet1.Range("A1:C200")
    firstblankrownumber = FirstBlankRow(rngToSearch)
    Debug.Print firstblankrownumber

End Sub

Function FirstBlankRow(ByVal rngToSearch As Range, Optional activeCell As Range) As Long
Dim FirstBlankCell As Range

    If activeCell Is Nothing Then Set activeCell = rngToSearch.Cells(1, 1)
    'Check first cell isn't empty
    If WorksheetFunction.CountA(rngToSearch.Cells(1, 1).EntireRow) = 0 Then
        FirstBlankRow = rngToSearch.Cells(1, 1).Row
    Else

        Set FirstBlankCell = rngToSearch.FindNext(After:=activeCell)
        If Not FirstBlankCell Is Nothing Then

            If WorksheetFunction.CountA(FirstBlankCell.EntireRow) = 0 Then
                FirstBlankRow = FirstBlankCell.Row
            Else
                Set activeCell = FirstBlankCell
                FirstBlankRow = FirstBlankRow(rngToSearch, activeCell)

            End If
        Else
            'no empty cell in range searched
        End If
    End If
End Function

You can do this:

select *
from user_source
where upper(text) like upper('%SOMETEXT%');

Alternatively, SQL Developer has a built-in report to do this under:

View > Reports > Data Dictionary Reports > PLSQL > Search Source Code

The 11G docs for USER_SOURCE are here

Unless you are subtracting dates on same browser client and don't care about edge cases like day light saving time changes, you are probably better off using moment.js which offers powerful localized APIs. For example, this is what I have in my utils.js:

subtractDates: function(date1, date2) {
    return moment.subtract(date1, date2).milliseconds();
},
millisecondsSince: function(dateSince) {
    return moment().subtract(dateSince).milliseconds();
},

Also try System.currentTimeMillis()

Right, many alternatives are listed. The easiest and cleanest would be just using the enhanced for statement as below. The Expression is of some type that is iterable.

for ( FormalParameter : Expression ) Statement

For example, to iterate through, List<String> ids, we can simply so,

for (String str : ids) {
    // Do something
}

use Dexter library

Include the library in your build.gradle

dependencies{
    implementation 'com.karumi:dexter:4.2.0'
}

this example requests WRITE_EXTERNAL_STORAGE.

Dexter.withActivity(this)
                .withPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)
                .withListener(new PermissionListener() {
                    @Override
                    public void onPermissionGranted(PermissionGrantedResponse response) {
                        // permission is granted, open the camera
                    }

                    @Override
                    public void onPermissionDenied(PermissionDeniedResponse response) {
                        // check for permanent denial of permission
                        if (response.isPermanentlyDenied()) {
                            // navigate user to app settings
                        }
                    }

                    @Override
                    public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
                        token.continuePermissionRequest();
                    }
                }).check();

You really just need a single struct, and as mentioned in the comments the correct annotations on the field will yield the desired results. JSON is not some extremely variant data format, it is well defined and any piece of json, no matter how complicated and confusing it might be to you can be represented fairly easily and with 100% accuracy both by a schema and in objects in Go and most other OO programming languages. Here's an example;

package main

import (
    "fmt"
    "encoding/json"
)

type Data struct {
    Votes *Votes `json:"votes"`
    Count string `json:"count,omitempty"`
}

type Votes struct {
    OptionA string `json:"option_A"`
}

func main() {
    s := `{ "votes": { "option_A": "3" } }`
    data := &Data{
        Votes: &Votes{},
    }
    err := json.Unmarshal([]byte(s), data)
    fmt.Println(err)
    fmt.Println(data.Votes)
    s2, _ := json.Marshal(data)
    fmt.Println(string(s2))
    data.Count = "2"
    s3, _ := json.Marshal(data)
    fmt.Println(string(s3))
}

https://play.golang.org/p/ScuxESTW5i

Based on your most recent comment you could address that by using an interface{} to represent data besides the count, making the count a string and having the rest of the blob shoved into the interface{} which will accept essentially anything. That being said, Go is a statically typed language with a fairly strict type system and to reiterate, your comments stating 'it can be anything' are not true. JSON cannot be anything. For any piece of JSON there is schema and a single schema can define many many variations of JSON. I advise you take the time to understand the structure of your data rather than hacking something together under the notion that it cannot be defined when it absolutely can and is probably quite easy for someone who knows what they're doing.

I had the same problem.

system configuration:-single system with window 7 sp1 server and client both are installed on same system

I was trying to access the window desktop. As some the answer say that your Sqlserver service don't have full access to the directory. This is totally right.

I solved this problem by doing a few simple steps

1. Go to All Programs->microsoft sql server 2008 -> configuration tools and then select sql server configuration manager.
2. Select the service and go to properties. In the build in Account dialog box select local system and then select ok button.

Steps 3 and 4 in image are demo with accessing the folder

I would define $Version as a string to start with

[string]$Version

and if it's a param you can use the code posted by Samselvaprabu or if you would rather not present your users with an error you can do something like

while (-not($version)){
    $version = Read-Host "Enter the version ya fool!"
}
$request += "/" + $version

If I had to guess, you did this:

import datetime

at the top of your code. This means that you have to do this:

datetime.datetime.strptime(date, "%Y-%m-%d")

to access the strptime method. Or, you could change the import statement to this:

from datetime import datetime

and access it as you are.

The people who made the datetime module also named their class datetime:

#module  class    method
datetime.datetime.strptime(date, "%Y-%m-%d")

I've been trying to get this code to work for the last 2 hours and though it showed no error on the simulator, there was one on the device.

Turns out, at least in my case that the error came from directory used (bundle) :

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/recordTest.caf", [[NSBundle mainBundle] resourcePath]]];

It was not writable or something like this... There was no error except the fact that prepareToRecord failed...

I therefore replaced it by :

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *recDir = [paths objectAtIndex:0];
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/recordTest.caf", recDir]]

It now Works like a Charm.

Hope this helps others.

You can run Git (not the whole Github) via Apache HTTP Server, so that you host the Git repo on your server's filesystem and expose it via HTTP. You get all Git functionalities, but obviously you won't be able to pull-request or track issues. Any tool attached to your self-hosted Git repo can implement the rest of the features.

The warning comes up because Tomcat scans all Jars for TLDs (Tagging Library Definitions).

Step1: To see which JARs are throwing up this warning, insert he following line to tomcat/conf/logging.properties

org.apache.jasper.servlet.TldScanner.level = FINE

Now you should be able to see warnings with a detail of which JARs are causing the intial warning

Step2 Since skipping unneeded JARs during scanning can improve startup time and JSP compilation time, we will skip un-needed JARS in the catalina.properties file. You have two options here -

1. List all the JARs under the tomcat.util.scan.StandardJarScanFilter.jarsToSkip. But this can get cumbersome if you have a lot jars or if the jars keep changing.
2. Alternatively, Insert tomcat.util.scan.StandardJarScanFilter.jarsToSkip=* to skip all the jars

You should now not see the above warnings and if you have a considerably large application, it should save you significant time in deploying an application.

Note: Tested in Tomcat8

I too faced this problem when loading an 'http' url in WKWebView in iOS 11, it is working fine with https.

What worked for me was setting App transport setting in info.pist file to allow arbitary load.

<key>NSAppTransportSecurity</key>
    <dict>
        <!--Not a recommended way, there are better solutions available-->
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>

ORDER BY: sort the data in ascending or descending order.

Consider the CUSTOMERS table:

+----+----------+-----+-----------+----------+
| ID | NAME     | AGE | ADDRESS   | SALARY   |
+----+----------+-----+-----------+----------+
|  1 | Ramesh   |  32 | Ahmedabad |  2000.00 |
|  2 | Khilan   |  25 | Delhi     |  1500.00 |
|  3 | kaushik  |  23 | Kota      |  2000.00 |
|  4 | Chaitali |  25 | Mumbai    |  6500.00 |
|  5 | Hardik   |  27 | Bhopal    |  8500.00 |
|  6 | Komal    |  22 | MP        |  4500.00 |
|  7 | Muffy    |  24 | Indore    | 10000.00 |
+----+----------+-----+-----------+----------+

Following is an example, which would sort the result in ascending order by NAME:

SQL> SELECT * FROM CUSTOMERS
     ORDER BY NAME;

This would produce the following result:

+----+----------+-----+-----------+----------+
| ID | NAME     | AGE | ADDRESS   | SALARY   |
+----+----------+-----+-----------+----------+
|  4 | Chaitali |  25 | Mumbai    |  6500.00 |
|  5 | Hardik   |  27 | Bhopal    |  8500.00 |
|  3 | kaushik  |  23 | Kota      |  2000.00 |
|  2 | Khilan   |  25 | Delhi     |  1500.00 |
|  6 | Komal    |  22 | MP        |  4500.00 |
|  7 | Muffy    |  24 | Indore    | 10000.00 |
|  1 | Ramesh   |  32 | Ahmedabad |  2000.00 |
+----+----------+-----+-----------+----------+

GROUP BY: arrange identical data into groups.

Now, CUSTOMERS table has the following records with duplicate names:

+----+----------+-----+-----------+----------+
| ID | NAME     | AGE | ADDRESS   | SALARY   |
+----+----------+-----+-----------+----------+
|  1 | Ramesh   |  32 | Ahmedabad |  2000.00 |
|  2 | Ramesh   |  25 | Delhi     |  1500.00 |
|  3 | kaushik  |  23 | Kota      |  2000.00 |
|  4 | kaushik  |  25 | Mumbai    |  6500.00 |
|  5 | Hardik   |  27 | Bhopal    |  8500.00 |
|  6 | Komal    |  22 | MP        |  4500.00 |
|  7 | Muffy    |  24 | Indore    | 10000.00 |
+----+----------+-----+-----------+----------+

if you want to group identical names into single name, then GROUP BY query would be as follows:

SQL> SELECT * FROM CUSTOMERS
     GROUP BY NAME;

This would produce the following result: (for identical names it would pick the last one and finally sort the column in ascending order)

    +----+----------+-----+-----------+----------+   
    | ID | NAME     | AGE | ADDRESS   | SALARY   |
    +----+----------+-----+-----------+----------+
    |  5 | Hardik   |  27 | Bhopal    |  8500.00 |
    |  4 | kaushik  |  25 | Mumbai    |  6500.00 |
    |  6 | Komal    |  22 | MP        |  4500.00 |
    |  7 | Muffy    |  24 | Indore    | 10000.00 |
    |  2 | Ramesh   |  25 | Delhi     |  1500.00 |
    +----+----------+-----+-----------+----------+

as you have inferred that it is of no use without SQL functions like sum,avg etc..

so go through this definition to understand the proper use of GROUP BY:

A GROUP BY clause works on the rows returned by a query by summarizing identical rows into a single/distinct group and returns a single row with the summary for each group, by using appropriate Aggregate function in the SELECT list, like COUNT(), SUM(), MIN(), MAX(), AVG(), etc.

Now, if you want to know the total amount of salary on each customer(name), then GROUP BY query would be as follows:

SQL> SELECT NAME, SUM(SALARY) FROM CUSTOMERS
     GROUP BY NAME;

This would produce the following result: (sum of the salaries of identical names and sort the NAME column after removing identical names)

+---------+-------------+
| NAME    | SUM(SALARY) |
+---------+-------------+
| Hardik  |     8500.00 |
| kaushik |     8500.00 |
| Komal   |     4500.00 |
| Muffy   |    10000.00 |
| Ramesh  |     3500.00 |
+---------+-------------+

Not 100%; however, it sounds like the heap is an object or set of allocated space (on RAM) that is built into the functionality of the code either Java itself or more likely functionality from ehcache itself, and the off-heap Ram is there own system as well; however, it sounds like this is one magnitude slower as it is not as organized, meaning it may not use a heap (meaning one long set of space of ram), and instead uses different address spaces likely making it slightly less efficient.

Then of course the next tier lower is hard-drive space itself.

I don't use ehcache, so you may not want to trust me, but that what is what I gathered from their documentation.

I whould choose swing just because it's "native" for java.

Plus, have a look at http://swingx.java.net/.

What is yield?

The yield keyword returns data from a generator function:

The heart of a generator function is the yield keyword. In its simplest form, a yield statement looks much like a return statement, except that instead of stopping execution of the function and returning, yield instead provides a value to the code looping over the generator and pauses execution of the generator function.

What is a generator function?

A generator function is effectively a more compact and efficient way to write an Iterator. It allows you to define a function (your xrange) that will calculate and return values while you are looping over it:

function xrange($min, $max) {
    for ($i = $min; $i <= $max; $i++) {
        yield $i;
    }
}

[…]

foreach (xrange(1, 10) as $key => $value) {
    echo "$key => $value", PHP_EOL;
}

This would create the following output:

0 => 1
1 => 2
…
9 => 10

You can also control the $key in the foreach by using

yield $someKey => $someValue;

In the generator function, $someKey is whatever you want appear for $key and $someValue being the value in $val. In the question's example that's $i.

What's the difference to normal functions?

Now you might wonder why we are not simply using PHP's native range function to achieve that output. And right you are. The output would be the same. The difference is how we got there.

When we use range PHP, will execute it, create the entire array of numbers in memory and return that entire array to the foreach loop which will then go over it and output the values. In other words, the foreach will operate on the array itself. The range function and the foreach only "talk" once. Think of it like getting a package in the mail. The delivery guy will hand you the package and leave. And then you unwrap the entire package, taking out whatever is in there.

When we use the generator function, PHP will step into the function and execute it until it either meets the end or a yield keyword. When it meets a yield, it will then return whatever is the value at that time to the outer loop. Then it goes back into the generator function and continues from where it yielded. Since your xrange holds a for loop, it will execute and yield until $max was reached. Think of it like the foreach and the generator playing ping pong.

Why do I need that?

Obviously, generators can be used to work around memory limits. Depending on your environment, doing a range(1, 1000000) will fatal your script whereas the same with a generator will just work fine. Or as Wikipedia puts it:

Because generators compute their yielded values only on demand, they are useful for representing sequences that would be expensive or impossible to compute at once. These include e.g. infinite sequences and live data streams.

Generators are also supposed to be pretty fast. But keep in mind that when we are talking about fast, we are usually talking in very small numbers. So before you now run off and change all your code to use generators, do a benchmark to see where it makes sense.

Another Use Case for Generators is asynchronous coroutines. The yield keyword does not only return values but it also accepts them. For details on this, see the two excellent blog posts linked below.

Since when can I use yield?

Generators have been introduced in PHP 5.5. Trying to use yield before that version will result in various parse errors, depending on the code that follows the keyword. So if you get a parse error from that code, update your PHP.

• The original RFC
• kelunik's blog: An introduction to generators

Non-numpy functions like math.abs() or math.log10() don't play nicely with numpy arrays. Just replace the line raising an error with:

m = np.log10(np.abs(x))

Apart from that the np.polyfit() call will not work because it is missing a parameter (and you are not assigning the result for further use anyway).

If you want to see output logs from all the services in your terminal.

docker-compose logs -t -f --tail <no of lines> 

Eg.: Say you would like to log output of last 5 lines from all service

docker-compose logs -t -f --tail 5

If you wish to log output from specific services then it can be done as below:

docker-compose logs -t -f --tail <no of lines> <name-of-service1> <name-of-service2> ... <name-of-service N>

Usage:

Eg. say you have API and portal services then you can do something like below :

docker-compose logs -t -f --tail 5 portal api

Where 5 represents last 5 lines from both logs.

In VS Code...

1. Go to Explorer (Ctrl + Shift + E)
2. Right click on your favorite folder
3. Select "Find in folder"

The search query will be prefilled with the path under "files to include".

So, not directly related but this is the first question that appears when you try to find how to terminate a process running from a specific folder using Python.

It also answers the question in a way(even though it is an old one with lots of answers).

While creating a faster way to scrape some government sites for data I had an issue where if any of the processes in the pool got stuck they would be skipped but still take up memory from my computer. This is the solution I reached for killing them, if anyone knows a better way to do it please let me know!

import pandas as pd
import wmi
from re import escape
import os

def kill_process(kill_path, execs):
    f = wmi.WMI()
    esc = escape(kill_path)
    temp = {'id':[], 'path':[], 'name':[]}
    for process in f.Win32_Process():
        temp['id'].append(process.ProcessId)
        temp['path'].append(process.ExecutablePath)
        temp['name'].append(process.Name)
    temp = pd.DataFrame(temp)
    temp = temp.dropna(subset=['path']).reset_index().drop(columns=['index'])
    temp = temp.loc[temp['path'].str.contains(esc)].loc[temp.name.isin(execs)].reset_index().drop(columns=['index'])
    [os.system('taskkill /PID {} /f'.format(t)) for t in temp['id']]

for (int i=0;i < Table.Rows.Count;i++)
{
      Var YourValue = Table.Rows[i]["ColumnName"];
}

I was facing the same error inside DockerFile during build time while the image was public. I did little modification in Dockerfile.

 RUN git clone  https://github.com/kacole2/express-node-mongo-skeleton.git /www/nodejs

This would be because using the [email protected]:... syntax ends up > using SSH to clone, and inside the container, your private key is not > available. You'll want to use RUN git clone > https://github.com/edenhill/librdkafka.git instead.

In xcode 7.3 I still got the same error,my certificate was provisional profile was also meaning everything was fine still I was getting the same error, and I was unable to delete the provisional profile in xcode perferences,so I right clicked on provisional profile which give option to move to trash when I clicked nothing happened but when I closed the the preference window and open it again by Command, the provisional profile was gone and download option was visible, I clicked download and it starting working fine

This question is enormously old but is still the top result on google when you search for ways to try to disable this popup message as an extension developer who hasn't added their extension to the chrome store, doesn't have access to group policies due to their OS, and is not using the chrome dev build. There is currently no official solution in this circumstance so I'll post a somewhat 'hacky' one here.

This method has us immediately create a new window and close the old one. The popup window is associated with the original window so in normal use cases the popup never appears since that window gets closed.

The simplest solution here is we create a new window, and we close all windows that are not the window we just created in the callback:

chrome.windows.create({
    type: 'normal',
    focused: true,
    state: 'maximized'
}, function(window) {
    chrome.windows.getAll(function(windows) {
        for (var i = 0; i < windows.length; i++) {
            if (windows[i].id != window.id) {
                chrome.windows.remove(windows[i].id);
            }
        }
    });
});

Additionally we can detect how this extension is installed and only run this code if it is a development install (although probably best to completely remove altogether from release code). First we create the callback function for a chrome.management.getSelf call which allows us to check the extension's install type, which is basically just wrapping the code above in an if statement:

function suppress_dev_warning(info) {
    if (info.installType == "development") {
        chrome.windows.create({
            type: 'normal',
            focused: true,
            state: 'maximized'
        }, function(window) {
            chrome.windows.getAll(function(windows) {
                for (var i = 0; i < windows.length; i++) {
                    if (windows[i].id != window.id) {
                        chrome.windows.remove(windows[i].id);
                    }
                }
            });
        });
    }
}

next we call chrome.management.getSelf with the callback we made:

chrome.management.getSelf(suppress_dev_warning);

This method has some caveats, namely we are assuming a persistent background page which means the code runs only once when chrome is first opened. A second issue is that if we reload/refresh the extension from the chrome://extensions page, it will close all windows that are currently open and in my experience sometimes display the warning anyways. This special case can be avoided by checking if any tabs are open to "chrome://extensions" and not executing if they are.

>>> a=range(1,10)
>>> for i in [2,3,7]: a.remove(i)
...
>>> a

>>> b=map(a.remove,[2,3,7])
>>> a
[1, 4, 5, 6, 8, 9]

2. If ERROR 1229 (HY000): Variable 'event_scheduler' is a GLOBAL variable and should be set with SET GLOBAL: mportant

It is possible to set the Event Scheduler to DISABLED only at server startup. If event_scheduler is ON or OFF, you cannot set it to DISABLED at runtime. Also, if the Event Scheduler is set to DISABLED at startup, you cannot change the value of event_scheduler at runtime.

To disable the event scheduler, use one of the following two methods:

1. As a command-line option when starting the server:

   --event-scheduler=DISABLED
   

2. In the server configuration file (my.cnf, or my.ini on Windows systems): include the line where it will be read by the server (for example, in a [mysqld] section):

   event_scheduler=DISABLED
   

   Read MySQL documentation for more information.

    DROP EVENT IF EXISTS EVENT_NAME;
     CREATE EVENT EVENT_NAME
    ON SCHEDULE EVERY 10 SECOND/minute/hour
    DO
    CALL PROCEDURE_NAME();
   

$('.theClass:checkbox:checked') will give you all the checked checkboxes with the class theClass.

You could test the url via AJAX and read the status code - that is if the URL is in the same domain.

If it's a remote domain, you could have a server script on your own domain check out a remote URL.

In the code you have posted there would be no advantages, as you are misusing the StringBuilder. You build the same String in both cases. Using StringBuilder you can avoid the + operation on Strings using the append method. You should use it this way:

return new StringBuilder("select id1, ").append(" id2 ").append(" from ").append(" table").toString();

In Java, the String type is an inmutable sequence of characters, so when you add two Strings the VM creates a new String value with both operands concatenated.

StringBuilder provides a mutable sequence of characters, which you can use to concat different values or variables without creating new String objects, and so it can sometimes be more efficient than working with strings

This provides some useful features, as changing the content of a char sequence passed as parameter inside another method, which you can't do with Strings.

private void addWhereClause(StringBuilder sql, String column, String value) {
   //WARNING: only as an example, never append directly a value to a SQL String, or you'll be exposed to SQL Injection
   sql.append(" where ").append(column).append(" = ").append(value);
}

Something like this:

var objects = [
  {
    "foo" : "bar",
    "bar" : "sit"
  },
  {
    "foo" : "lorem",
    "bar" : "ipsum"
  },
  {
    "foo" : "dolor",
    "bar" : "amet"
  }
];

var results = [];

var toSearch = "lo";

for(var i=0; i<objects.length; i++) {
  for(key in objects[i]) {
    if(objects[i][key].indexOf(toSearch)!=-1) {
      results.push(objects[i]);
    }
  }
}

The results array will contain all matched objects.

If you search for 'lo', the result will be like:

[{ foo="lorem", bar="ipsum"}, { foo="dolor", bar="amet"}]

NEW VERSION - Added trim code, code to ensure no duplicates in result set.

function trimString(s) {
  var l=0, r=s.length -1;
  while(l < s.length && s[l] == ' ') l++;
  while(r > l && s[r] == ' ') r-=1;
  return s.substring(l, r+1);
}

function compareObjects(o1, o2) {
  var k = '';
  for(k in o1) if(o1[k] != o2[k]) return false;
  for(k in o2) if(o1[k] != o2[k]) return false;
  return true;
}

function itemExists(haystack, needle) {
  for(var i=0; i<haystack.length; i++) if(compareObjects(haystack[i], needle)) return true;
  return false;
}

var objects = [
  {
    "foo" : "bar",
    "bar" : "sit"
  },

    "foo" : "lorem",
    "bar" : "ipsum"
  },
  {
    "foo" : "dolor blor",
    "bar" : "amet blo"
  }
];

function searchFor(toSearch) {
  var results = [];
  toSearch = trimString(toSearch); // trim it
  for(var i=0; i<objects.length; i++) {
    for(var key in objects[i]) {
      if(objects[i][key].indexOf(toSearch)!=-1) {
        if(!itemExists(results, objects[i])) results.push(objects[i]);
      }
    }
  }
  return results;
}

console.log(searchFor('lo '));

This question is a bit tricky before Jan 2013 and matplotlib 1.3.1 (Aug 2013), which is the oldest stable version you can find on matpplotlib website. But after that it is quite trivial.

Because present version of matplotlib.pylab.scatter support assigning: array of colour name string, array of float number with colour map, array of RGB or RGBA.

this answer is dedicate to @Oxinabox's endless passion for correcting the 2013 version of myself in 2015.

you have two option of using scatter command with multiple colour in a single call.

1. as pylab.scatter command support use RGBA array to do whatever colour you want;

2. back in early 2013, there is no way to do so, since the command only support single colour for the whole scatter point collection. When I was doing my 10000-line project I figure out a general solution to bypass it. so it is very tacky, but I can do it in whatever shape, colour, size and transparent. this trick also could be apply to draw path collection, line collection....

the code is also inspired by the source code of pyplot.scatter, I just duplicated what scatter does without trigger it to draw.

the command pyplot.scatter return a PatchCollection Object, in the file "matplotlib/collections.py" a private variable _facecolors in Collection class and a method set_facecolors.

so whenever you have a scatter points to draw you can do this:

# rgbaArr is a N*4 array of float numbers you know what I mean
# X is a N*2 array of coordinates
# axx is the axes object that current draw, you get it from
# axx = fig.gca()

# also import these, to recreate the within env of scatter command 
import matplotlib.markers as mmarkers
import matplotlib.transforms as mtransforms
from matplotlib.collections import PatchCollection
import matplotlib.markers as mmarkers
import matplotlib.patches as mpatches


# define this function
# m is a string of scatter marker, it could be 'o', 's' etc..
# s is the size of the point, use 1.0
# dpi, get it from axx.figure.dpi
def addPatch_point(m, s, dpi):
    marker_obj = mmarkers.MarkerStyle(m)
    path = marker_obj.get_path()
    trans = mtransforms.Affine2D().scale(np.sqrt(s*5)*dpi/72.0)
    ptch = mpatches.PathPatch(path, fill = True, transform = trans)
    return ptch

patches = []
# markerArr is an array of maker string, ['o', 's'. 'o'...]
# sizeArr is an array of size float, [1.0, 1.0. 0.5...]

for m, s in zip(markerArr, sizeArr):
    patches.append(addPatch_point(m, s, axx.figure.dpi))

pclt = PatchCollection(
                patches,
                offsets = zip(X[:,0], X[:,1]),
                transOffset = axx.transData)

pclt.set_transform(mtransforms.IdentityTransform())
pclt.set_edgecolors('none') # it's up to you
pclt._facecolors = rgbaArr

# in the end, when you decide to draw
axx.add_collection(pclt)
# and call axx's parent to draw_idle()

Import the JavaScript file jquery.validate.min.js.

You can use this method:

$.validator.addMethod("pwcheck", function (value) {
    return /[\@\#\$\%\^\&\*\(\)\_\+\!]/.test(value) && /[a-z]/.test(value) && /[0-9]/.test(value) && /[A-Z]/.test(value)
});

1. At least one upper case English letter
2. At least one lower case English letter
3. At least one digit
4. At least one special character

There are different ways to do so. You can use DateTime.Now.ToLongTimeString() which returns only the time in string format.

Use jquery change event

Description: Bind an event handler to the "change" JavaScript event, or trigger that event on an element.

An example

$("input[type='text']").change( function() {
  // your code
});

The advantage that .change has over .keypress , .focus , .blur is that .change event will fire only when input has changed

This was a problem for me, too. One reason for doing this (in my case) was that I needed to convert a client-side event (a javascript variable being modified) to a server-side variable (for that variable to be used in php). Hence populating a form with a javascript variable (eg a sessionStorage key/value) and converting it to a $_POST variable.

<form name='formName'>
<input name='inputName'>
</form>

<script>
document.formName.inputName.value=var
</script>

RedirectToAction("actionName", "controllerName");

It has other overloads as well, please check up!

Also, If you are new and you are not using T4MVC, then I would recommend you to use it!

It gives you intellisence for actions,Controllers,views etc (no more magic strings)

There are two primary ways that pandas makes selections from a DataFrame.

• By Label
• By Integer Location

The documentation uses the term position for referring to integer location. I do not like this terminology as I feel it is confusing. Integer location is more descriptive and is exactly what .iloc stands for. The key word here is INTEGER - you must use integers when selecting by integer location.

Before showing the summary let's all make sure that ...

.ix is deprecated and ambiguous and should never be used

There are three primary indexers for pandas. We have the indexing operator itself (the brackets []), .loc, and .iloc. Let's summarize them:

• [] - Primarily selects subsets of columns, but can select rows as well. Cannot simultaneously select rows and columns.
• .loc - selects subsets of rows and columns by label only
• .iloc - selects subsets of rows and columns by integer location only

I almost never use .at or .iat as they add no additional functionality and with just a small performance increase. I would discourage their use unless you have a very time-sensitive application. Regardless, we have their summary:

• .at selects a single scalar value in the DataFrame by label only
• .iat selects a single scalar value in the DataFrame by integer location only

In addition to selection by label and integer location, boolean selection also known as boolean indexing exists.

Examples explaining .loc, .iloc, boolean selection and .at and .iat are shown below

We will first focus on the differences between .loc and .iloc. Before we talk about the differences, it is important to understand that DataFrames have labels that help identify each column and each row. Let's take a look at a sample DataFrame:

df = pd.DataFrame({'age':[30, 2, 12, 4, 32, 33, 69],
                   'color':['blue', 'green', 'red', 'white', 'gray', 'black', 'red'],
                   'food':['Steak', 'Lamb', 'Mango', 'Apple', 'Cheese', 'Melon', 'Beans'],
                   'height':[165, 70, 120, 80, 180, 172, 150],
                   'score':[4.6, 8.3, 9.0, 3.3, 1.8, 9.5, 2.2],
                   'state':['NY', 'TX', 'FL', 'AL', 'AK', 'TX', 'TX']
                   },
                  index=['Jane', 'Nick', 'Aaron', 'Penelope', 'Dean', 'Christina', 'Cornelia'])

All the words in bold are the labels. The labels, age, color, food, height, score and state are used for the columns. The other labels, Jane, Nick, Aaron, Penelope, Dean, Christina, Cornelia are used as labels for the rows. Collectively, these row labels are known as the index.

The primary ways to select particular rows in a DataFrame are with the .loc and .iloc indexers. Each of these indexers can also be used to simultaneously select columns but it is easier to just focus on rows for now. Also, each of the indexers use a set of brackets that immediately follow their name to make their selections.

.loc selects data only by labels

We will first talk about the .loc indexer which only selects data by the index or column labels. In our sample DataFrame, we have provided meaningful names as values for the index. Many DataFrames will not have any meaningful names and will instead, default to just the integers from 0 to n-1, where n is the length(number of rows) of the DataFrame.

There are many different inputs you can use for .loc three out of them are

• A string
• A list of strings
• Slice notation using strings as the start and stop values

Selecting a single row with .loc with a string

To select a single row of data, place the index label inside of the brackets following .loc.

df.loc['Penelope']

This returns the row of data as a Series

age           4
color     white
food      Apple
height       80
score       3.3
state        AL
Name: Penelope, dtype: object

Selecting multiple rows with .loc with a list of strings

df.loc[['Cornelia', 'Jane', 'Dean']]

This returns a DataFrame with the rows in the order specified in the list:

Selecting multiple rows with .loc with slice notation

Slice notation is defined by a start, stop and step values. When slicing by label, pandas includes the stop value in the return. The following slices from Aaron to Dean, inclusive. Its step size is not explicitly defined but defaulted to 1.

df.loc['Aaron':'Dean']

Complex slices can be taken in the same manner as Python lists.

.iloc selects data only by integer location

Let's now turn to .iloc. Every row and column of data in a DataFrame has an integer location that defines it. This is in addition to the label that is visually displayed in the output. The integer location is simply the number of rows/columns from the top/left beginning at 0.

There are many different inputs you can use for .iloc three out of them are

• An integer
• A list of integers
• Slice notation using integers as the start and stop values

Selecting a single row with .iloc with an integer

df.iloc[4]

This returns the 5th row (integer location 4) as a Series

age           32
color       gray
food      Cheese
height       180
score        1.8
state         AK
Name: Dean, dtype: object

Selecting multiple rows with .iloc with a list of integers

df.iloc[[2, -2]]

This returns a DataFrame of the third and second to last rows:

Selecting multiple rows with .iloc with slice notation

df.iloc[:5:3]

Simultaneous selection of rows and columns with .loc and .iloc

One excellent ability of both .loc/.iloc is their ability to select both rows and columns simultaneously. In the examples above, all the columns were returned from each selection. We can choose columns with the same types of inputs as we do for rows. We simply need to separate the row and column selection with a comma.

For example, we can select rows Jane, and Dean with just the columns height, score and state like this:

df.loc[['Jane', 'Dean'], 'height':]

This uses a list of labels for the rows and slice notation for the columns

We can naturally do similar operations with .iloc using only integers.

df.iloc[[1,4], 2]
Nick      Lamb
Dean    Cheese
Name: food, dtype: object

Simultaneous selection with labels and integer location

.ix was used to make selections simultaneously with labels and integer location which was useful but confusing and ambiguous at times and thankfully it has been deprecated. In the event that you need to make a selection with a mix of labels and integer locations, you will have to make both your selections labels or integer locations.

For instance, if we want to select rows Nick and Cornelia along with columns 2 and 4, we could use .loc by converting the integers to labels with the following:

col_names = df.columns[[2, 4]]
df.loc[['Nick', 'Cornelia'], col_names] 

Or alternatively, convert the index labels to integers with the get_loc index method.

labels = ['Nick', 'Cornelia']
index_ints = [df.index.get_loc(label) for label in labels]
df.iloc[index_ints, [2, 4]]

Boolean Selection

The .loc indexer can also do boolean selection. For instance, if we are interested in finding all the rows where age is above 30 and return just the food and score columns we can do the following:

df.loc[df['age'] > 30, ['food', 'score']] 

You can replicate this with .iloc but you cannot pass it a boolean series. You must convert the boolean Series into a numpy array like this:

df.iloc[(df['age'] > 30).values, [2, 4]] 

Selecting all rows

It is possible to use .loc/.iloc for just column selection. You can select all the rows by using a colon like this:

df.loc[:, 'color':'score':2]

The indexing operator, [], can slice can select rows and columns too but not simultaneously.

Most people are familiar with the primary purpose of the DataFrame indexing operator, which is to select columns. A string selects a single column as a Series and a list of strings selects multiple columns as a DataFrame.

df['food']

Jane          Steak
Nick           Lamb
Aaron         Mango
Penelope      Apple
Dean         Cheese
Christina     Melon
Cornelia      Beans
Name: food, dtype: object

Using a list selects multiple columns

df[['food', 'score']]

What people are less familiar with, is that, when slice notation is used, then selection happens by row labels or by integer location. This is very confusing and something that I almost never use but it does work.

df['Penelope':'Christina'] # slice rows by label

df[2:6:2] # slice rows by integer location

The explicitness of .loc/.iloc for selecting rows is highly preferred. The indexing operator alone is unable to select rows and columns simultaneously.

df[3:5, 'color']
TypeError: unhashable type: 'slice'

Selection by .at and .iat

Selection with .at is nearly identical to .loc but it only selects a single 'cell' in your DataFrame. We usually refer to this cell as a scalar value. To use .at, pass it both a row and column label separated by a comma.

df.at['Christina', 'color']
'black'

Selection with .iat is nearly identical to .iloc but it only selects a single scalar value. You must pass it an integer for both the row and column locations

df.iat[2, 5]
'FL'

np.save('data.npy', num_arr) # save
new_num_arr = np.load('data.npy') # load

If anybody decides to use replace, you should try r'\n' instead '\n'

mystring = mystring.replace(r'\n', ' ').replace(r'\r', '')

NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.

You can use INSERT with SELECT UNION ALL:

INSERT INTO MyTable  (FirstCol, SecondCol)
    SELECT  'First' ,1
    UNION ALL
SELECT  'Second' ,2
    UNION ALL
SELECT  'Third' ,3
...

Only for small datasets though, which should be fine for your 4 records.

One way around this problem is to use stored procedures with an output parameter.

exec sp_mysprocname @returnvalue output, @firstparam = 1, @secondparam=2

values you do not pass in default to the defaults set in the stored procedure itself. And you can get the results from your output variable.

You may get this error when trying to browse an ASP.NET application.

The debug information shows that "This error can be caused by a virtual directory not being configured as an application in IIS."

However, this error occurs primarily out of two scenarios.

1. When you create an new web application using Visual Studio .NET, it automatically creates the virtual directory and configures it as an application. However, if you manually create the virtual directory and it is not configured as an application, then you will not be able to browse the application and may get the above error. The debug information you get as mentioned above, is applicable to this scenario.

To resolve it, right click on the virtual directory - select properties and then click on "Create" next to the "Application" Label and the text box. It will automatically create the "application" using the virtual directory's name. Now the application can be accessed.

2. When you have sub-directories in your application, you can have web.config file for the sub-directory. However, there are certain properties which cannot be set in the web.config of the sub-directory such as authentication, session state (you may see that the error message shows the line number where the authentication or session state is declared in the web.config of the sub-directory). The reason is, these settings cannot be overridden at the sub-directory level unless the sub-directory is also configured as an application (as mentioned in the above point).

Mostly, we have the practice of adding web.config in the sub-directory if we want to protect access to the sub-directory files (say, the directory is admin and we wish to protect the admin pages from unauthorized users).

If you can safely make (firstName, lastName) the PRIMARY KEY or at least put a UNIQUE key on them, then you could do this:

INSERT INTO logins (firstName, lastName, logins) VALUES ('Steve', 'Smith', 1)
ON DUPLICATE KEY UPDATE logins = logins + 1;

If you can't do that, then you'd have to fetch whatever that primary key is first, so I don't think you could achieve what you want in one query.

I just had the same problem. I declared a variable putting my text with the @.

@{
   var twitterSite = "@MyTwitterSite";
}

...

<meta name="twitter:site" content="@twitterSite">

I'm surprised no one offered this answer. It's not as "built-in" as Ruby's ||= but it's basically equivalent and still a one-liner:

foo = foo if 'foo' in locals() else 'default'

Of course, locals() is just a dictionary, so you can do:

foo = locals().get('foo', 'default')

<asp:GridView ID="GridView1" AutoGenerateEditButton="True" 
ondatabound="gv_DataBound" runat="server" DataSourceID="SqlDataSource1"
AutoGenerateColumns="False" width="600px">

<Columns>
                <asp:BoundField HeaderText="UserId" 
                DataField="UserId" 
                SortExpression="UserId" ItemStyle-Width="400px"></asp:BoundField>
   </Columns>
</asp:GridView>

I created this function that allows to enter a string and returns a list of string trimmed by any character

 func Trim(input:String, character:Character)-> [String]
{
    var collection:[String] = [String]()
    var index  = 0
    var copy = input
    let iterable = input
    var trim = input.startIndex.advancedBy(index)

    for i in iterable.characters

    {
        if (i == character)
        {

            trim = input.startIndex.advancedBy(index)
            // apennding to the list
            collection.append(copy.substringToIndex(trim))

            //cut the input
            index += 1
            trim = input.startIndex.advancedBy(index)
            copy = copy.substringFromIndex(trim)

            index = 0
        }
        else
        {
            index += 1
        }
    }
    collection.append(copy)
    return collection

}

as didn't found a way to do this in swift (compiles and work perfectly in swift 2.0)

Our server calls stored procs from Java like so - works on both SQL Server 2000 & 2008:

String SPsql = "EXEC <sp_name> ?,?";   // for stored proc taking 2 parameters
Connection con = SmartPoolFactory.getConnection();   // java.sql.Connection
PreparedStatement ps = con.prepareStatement(SPsql);
ps.setEscapeProcessing(true);
ps.setQueryTimeout(<timeout value>);
ps.setString(1, <param1>);
ps.setString(2, <param2>);
ResultSet rs = ps.executeQuery();

I wanted to add something very important. I use JohnnyHK method a lot but I noticed sometimes the changes didn't persist to the database. When I used .markModified it worked.

User.findOne({username: oldUsername}, function (err, user) {
   user.username = newUser.username;
   user.password = newUser.password;
   user.rights = newUser.rights;

   user.markModified(username)
   user.markModified(password)
   user.markModified(rights)
    user.save(function (err) {
    if(err) {
        console.error('ERROR!');
    }
});
});

tell mongoose about the change with doc.markModified('pathToYourDate') before saving.

You have to loop over the input array and add rules for each input as described here: Loop Over Rules

Here is a some code for ya:

$input = Request::all();
$rules = [];

foreach($input['name'] as $key => $val)
{
    $rules['name.'.$key] = 'required|distinct|min:3';
}

$rules['amount'] = 'required|integer|min:1';
$rules['description'] = 'required|string';

$validator = Validator::make($input, $rules);

//Now check validation:
if ($validator->fails()) 
{ 
  /* do something */ 
}

This is simple solution, which is using range function to pick alternative elements from a list of elements.

Note: This is only valid for an even numbered list.

a_list = [1, 2, 3, 4, 5, 6]
empty_list = [] 
for i in range(0, len(a_list), 2):
    empty_list.append(a_list[i] + a_list[i + 1])   
print(empty_list)
# [3, 7, 11]

You can also use:

your_dataframe.insert(loc=0, value=np.nan, column="")

where loc is your empty row index.

You could use php to echo the browser name as a body class, e.g.

<body class="mozilla">

Then, your conditional CSS would look like

.ie #container { top: 5px;}
.mozilla #container { top: 5px;}
.chrome #container { top: 5px;}

use array_rand()

see php manual -> http://php.net/manual/en/function.array-rand.php

This is just for the record since I bumped into this post when looking for a solution to my problem which was similar to the OP's.

In my case my jQuery Ajax request was prevented from succeeding due to same-origin policy in Chrome. All was resolved when I modified my server (Node.js) to do:

response.writeHead(200,
          {
            "Content-Type": "application/json",
            "Access-Control-Allow-Origin": "http://localhost:8080"
        });

It literally cost me an hour of banging my head against the wall. I am feeling stupid...

Above posts answers questions related to URL Encoding and How it works, but the original questions was "Should I URL-encode POST data?" which isn't answered.

From my recent experience with URL Encoding, I would like to extend the question further. "Should I URL-encode POST data, same as GET HTTP method. Generally, HTML Forms over the Browser if are filled, submitted and/or GET some information, Browsers will do URL Encoding but If an application exposes a web-service and expects Consumers to do URL-Encoding on data, is it Architecturally and Technically correct to do URL Encode with POST HTTP method ?"

You can try this:

return redirect()->back()->withInput(Input::all())->with('message', 'Something 
went wrong!');

You can use anycache to do the job for you. It considers all the details:

• It uses dill as backend, which extends the python pickle module to handle lambda and all the nice python features.
• It stores different objects to different files and reloads them properly.
• Limits cache size
• Allows cache clearing
• Allows sharing of objects between multiple runs
• Allows respect of input files which influence the result

Assuming you have a function myfunc which creates the instance:

from anycache import anycache

class Company(object):
    def __init__(self, name, value):
        self.name = name
        self.value = value

@anycache(cachedir='/path/to/your/cache')    
def myfunc(name, value)
    return Company(name, value)

Anycache calls myfunc at the first time and pickles the result to a file in cachedir using an unique identifier (depending on the function name and its arguments) as filename. On any consecutive run, the pickled object is loaded. If the cachedir is preserved between python runs, the pickled object is taken from the previous python run.

For any further details see the documentation

Just Javascript (as requested)

Add this function somewhere on your page (preferably in the <head>)

function clearBox(elementID)
{
    document.getElementById(elementID).innerHTML = "";
}

Then add the button on click event:

<button onclick="clearBox('cart_item')" />

In JQuery (for reference)

If you prefer JQuery you could do:

$("#cart_item").html("");

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

You need to trick the browser to use hardware acceleration more effectively. You can do this with an empty 3d transform:

-webkit-transform: translate3d(0,0,0)

Particularly, you'll need this on child elements that have a position:relative; declaration (or, just go all out and do it to all child elements).

Not a guaranteed fix, but fairly successful most of the time.

As noticed in comments start with sent_tokenize(), because word_tokenize() works only on a single sentence. You can filter out punctuation with filter(). And if you have an unicode strings make sure that is a unicode object (not a 'str' encoded with some encoding like 'utf-8').

from nltk.tokenize import word_tokenize, sent_tokenize

text = '''It is a blue, small, and extraordinary ball. Like no other'''
tokens = [word for sent in sent_tokenize(text) for word in word_tokenize(sent)]
print filter(lambda word: word not in ',-', tokens)

You could use the .attr() function:

$(this).attr('data-fullText')

or if you lowercase the attribute name:

data-fulltext="This is a span element"

then you could use the .data() function:

$(this).data('fulltext')

The .data() function expects and works only with lowercase attribute names.

Use try with resources. this will automatically close the resources.

try (BufferedReader br = new BufferedReader(new FileReader("C:/test.txt"))) {
    String line;
    while ((line = br.readLine()) != null) {
        System.out.println(line);
    }
} catch (Exception e) {

}

In the View, modify the current view or create a new view and make a filter change, select the radio button "Show items only when the following is true", in the below columns type "Created" and in the next dropdown select "is less than" and fill the next column [Today]-7.

The keyword [Today] denotes the current day for the calculation and this view will show as per your requirement

Mine was about

dispatch_group_leave(group)

was inside if closure in block. I just moved it out of closure.

I tried a few things, favouring pattern matching as a way of avoiding casting but ran into trouble with type erasure on the collection types.

The main problem seems to be that the complete type of the parse result mirrors the structure of the JSON data and is either cumbersome or impossible to fully state. I guess that is why Any is used to truncate the type definitions. Using Any leads to the need for casting.

I've hacked something below which is concise but is extremely specific to the JSON data implied by the code in the question. Something more general would be more satisfactory but I'm not sure if it would be very elegant.

implicit def any2string(a: Any)  = a.toString
implicit def any2boolean(a: Any) = a.asInstanceOf[Boolean]
implicit def any2double(a: Any)  = a.asInstanceOf[Double]

case class Language(name: String, isActive: Boolean, completeness: Double)

val languages = JSON.parseFull(jstr) match {
  case Some(x) => {
    val m = x.asInstanceOf[Map[String, List[Map[String, Any]]]]

    m("languages") map {l => Language(l("name"), l("isActive"), l("completeness"))}
  }
  case None => Nil
}

languages foreach {println}

this method uses recursion to descend into object hierarchy and generate rails style params which rails interprets as embedded hashes. objToParams generates a query string with an extra ampersand on the end, and objToQuery removes the final amperseand.

 function objToQuery(obj){
  let str = objToParams(obj,'');
  return str.slice(0, str.length);
}
function   objToParams(obj, subobj){
  let str = "";

   for (let key in obj) {
     if(typeof(obj[key]) === 'object') {
       if(subobj){
         str += objToParams(obj[key], `${subobj}[${key}]`);
       } else {
         str += objToParams(obj[key], `[${key}]`);
       }

     } else {
       if(subobj){
         str += `${key}${subobj}=${obj[key]}&`;
       }else{
         str += `${key}=${obj[key]}&`;
       }
     }
   }
   return str;
 }

I faced the same issue with a Foundation menu. align-self: center; didn't work for me.

My solution was to wrap the image with a <div style="display: inline-table;">...</div>

Based on @ofer.sheffer answer, this is the CMD variant for adding an affix (this is not the question, but this page is still the #1 google result if you search affix). It is a bit different because of the extension.

for %a in (*.*) do ren "%~a" "%~na-affix%~xa"

You can change the "-affix" part.

I have been working on this for some time now. Tough to get right, and I don't claim I do, but I'm happy with it so far. My code and several demos can be found at

• https://github.com/bauerca/drag-sort-listview

Its use is very similar to the TouchInterceptor (on which the code is based), although significant implementation changes have been made.

DragSortListView has smooth and predictable scrolling while dragging and shuffling items. Item shuffles are much more consistent with the position of the dragging/floating item. Heterogeneous-height list items are supported. Drag-scrolling is customizable (I demonstrate rapid drag scrolling through a long list---not that an application comes to mind). Headers/Footers are respected. etc.?? Take a look.

This will return auto increment value for the MySQL database and I didn't check with other databases. Please note that if you are using any other database, the query syntax may be different.

SELECT AUTO_INCREMENT 
FROM information_schema.tables
WHERE table_name = 'your_table_name'
     and table_schema = 'your_database_name';

SELECT AUTO_INCREMENT 
FROM information_schema.tables
WHERE table_name = 'your_table_name'
     and table_schema = database();

I'm using EF6, and I find something strange,

Suppose Customer has constructor with parameter ,

if I use new Customer(id, "name"), and do

 using (var db = new EfContext("name=EfSample"))
 {
    db.Customers.Add( new Customer(id, "name") );
    db.SaveChanges();
 }

It run through without error, but when I look into the DataBase, I find in fact that the data Is NOT be Inserted,

But if I add the curly brackets, use new Customer(id, "name"){} and do

 using (var db = new EfContext("name=EfSample"))
 {
    db.Customers.Add( new Customer(id, "name"){} );
    db.SaveChanges();
 }

the data will then actually BE Inserted,

seems the Curly Brackets make the difference, I guess that only when add Curly Brackets, entity framework will recognize this is a real concrete data.

SELECT * from games WHERE (lower(title) LIKE 'age of empires III');

The above query doesn't return any rows because you're looking for 'age of empires III' exact string which doesn't exists in any rows.

So in order to match with this string with different string which has 'age of empires' as substring you need to use '%your string goes here%'

More on mysql string comparision

You need to try this

SELECT * from games WHERE (lower(title) LIKE '%age of empires III%');

In Like '%age of empires III%' this will search for any matching substring in your rows, and it will show in results.

It's possible with JavaScript.

var elem = document.getElementById("myvideo");
if (elem.requestFullscreen) {
  elem.requestFullscreen();
} else if (elem.msRequestFullscreen) {
  elem.msRequestFullscreen();
} else if (elem.mozRequestFullScreen) {
  elem.mozRequestFullScreen();
} else if (elem.webkitRequestFullscreen) {
  elem.webkitRequestFullscreen();
}

There is no create or replace table in Oracle.

You must:

DROP TABLE foo;
CREATE TABLE foo (....);

I don't think that anybody has mentioned this, but alloca also has some serious security issues not necessarily present with malloc (though these issues also arise with any stack based arrays, dynamic or not). Since the memory is allocated on the stack, buffer overflows/underflows have much more serious consequences than with just malloc.

In particular, the return address for a function is stored on the stack. If this value gets corrupted, your code could be made to go to any executable region of memory. Compilers go to great lengths to make this difficult (in particular by randomizing address layout). However, this is clearly worse than just a stack overflow since the best case is a SEGFAULT if the return value is corrupted, but it could also start executing a random piece of memory or in the worst case some region of memory which compromises your program's security.

The following works for me... S3 objects:

s3://bucket/
    form1/
       section11/
          file111
          file112
       section12/
          file121
    form2/
       section21/
          file211
          file112
       section22/
          file221
          file222
          ...
      ...
   ...

Using:

from boto3.session import Session
s3client = session.client('s3')
resp = s3client.list_objects(Bucket=bucket, Prefix='', Delimiter="/")
forms = [x['Prefix'] for x in resp['CommonPrefixes']] 

we get:

form1/
form2/
...

With:

resp = s3client.list_objects(Bucket=bucket, Prefix='form1/', Delimiter="/")
sections = [x['Prefix'] for x in resp['CommonPrefixes']] 

we get:

form1/section11/
form1/section12/

Thanks everyone! I modified Winand's code slightly to export it to the user's desktop, no matter who is using the worksheet. I gave credit in the code to where I got the idea (thanks Kyle).

Sub ExportImage()


Dim sFilePath As String
Dim sView As String

'Captures current window view
sView = ActiveWindow.View

'Sets the current view to normal so there are no "Page X" overlays on the image
ActiveWindow.View = xlNormalView

'Temporarily disable screen updating
Application.ScreenUpdating = False

Set Sheet = ActiveSheet

'Set the file path to export the image to the user's desktop
'I have to give credit to Kyle for this solution, found it here:
'http://stackoverflow.com/questions/17551238/vba-how-to-save-excel-workbook-to-desktop-regardless-of-user
sFilePath = CreateObject("WScript.Shell").specialfolders("Desktop") & "\" & ActiveSheet.Name & ".png"

'Export print area as correctly scaled PNG image, courtasy of Winand
zoom_coef = 100 / Sheet.Parent.Windows(1).Zoom
Set area = Sheet.Range(Sheet.PageSetup.PrintArea)
area.CopyPicture xlPrinter
Set chartobj = Sheet.ChartObjects.Add(0, 0, area.Width * zoom_coef, area.Height * zoom_coef)
chartobj.Chart.Paste
chartobj.Chart.Export sFilePath, "png"
chartobj.Delete

'Returns to the previous view
ActiveWindow.View = sView

'Re-enables screen updating
Application.ScreenUpdating = True

'Tells the user where the image was saved
MsgBox ("Export completed! The file can be found here:" & Chr(10) & Chr(10) & sFilePath)

End Sub

In spring pre-3.0 it doesn't matter which one.

In spring 3.0 there's support for the standard (JSR-330) annotation @javax.inject.Inject - use it, with a combination of @Qualifier. Note that spring now also supports the @javax.inject.Qualifier meta-annotation:

@Qualifier
@Retention(RUNTIME)
public @interface YourQualifier {}

So you can have

<bean class="com.pkg.SomeBean">
   <qualifier type="YourQualifier"/>
</bean>

or

@YourQualifier
@Component
public class SomeBean implements Foo { .. }

And then:

@Inject @YourQualifier private Foo foo;

This makes less use of String-names, which can be misspelled and are harder to maintain.

As for the original question: both, without specifying any attributes of the annotation, perform injection by type. The difference is:

• @Resource allows you to specify a name of the injected bean
• @Autowired allows you to mark it as non-mandatory.

To be safe you don't break stuff (for example when these strings are changed in your code or further up), or crash you program (in case the returned string was literal for example like "hello I'm a literal string" and you start to edit it), make a copy of the returned string.

You could use strdup() for this, but read the small print. Or you can of course create your own version if it's not there on your platform.

Proper way to fix this issue is to change meta viewport to:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/>

Important: do not set minimum-scale! This keeps the page manually zoomable.

Below is the relevant code example for Angular 2/4/5 projects:

let headers = new Headers({
  'Content-Type': 'application/json'
});

let options = new RequestOptions({
  headers: headers,
  body: {
    id: 123
  }
});

return this.http.delete("http//delete.example.com/delete", options)
  .map((response: Response) => {
    return response.json()
  })
  .catch(err => {
    return err;
  });

Notice that body is passed through RequestOptions

EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable example does not need the mappedBy annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:

org.hibernate.AnnotationException: 
   Associations marked as mappedBy must not define database mappings 
   like @JoinTable or @JoinColumn

Let's pretend that you have an entity named Project and another entity named Task and each project can have many tasks.

You can design the database schema for this scenario in two ways.

The first solution is to create a table named Project and another table named Task and add a foreign key column to the task table named project_id:

Project      Task
-------      ----
id           id
name         name
             project_id

This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:

@Entity
public class Project {

   @OneToMany(mappedBy = "project")
   private Collection<Task> tasks;

}

@Entity
public class Task {

   @ManyToOne
   private Project project;

}

The other solution is to use a third table, e.g. Project_Tasks, and store the relationship between projects and tasks in that table:

Project      Task      Project_Tasks
-------      ----      -------------
id           id        project_id
name         name      task_id

The Project_Tasks table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:

Project entity:

@Entity
public class Project {

    @Id
    @GeneratedValue
    private Long pid;

    private String name;

    @JoinTable
    @OneToMany
    private List<Task> tasks;

    public Long getPid() {
        return pid;
    }

    public void setPid(Long pid) {
        this.pid = pid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }
}

Task entity:

@Entity
public class Task {

    @Id
    @GeneratedValue
    private Long tid;

    private String name;

    public Long getTid() {
        return tid;
    }

    public void setTid(Long tid) {
        this.tid = tid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

This will create the following database structure:

The @JoinTable annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks property like this:

@JoinTable(
        name = "MY_JT",
        joinColumns = @JoinColumn(
                name = "PROJ_ID",
                referencedColumnName = "PID"
        ),
        inverseJoinColumns = @JoinColumn(
                name = "TASK_ID",
                referencedColumnName = "TID"
        )
)
@OneToMany
private List<Task> tasks;

The resulting database would have become:

Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.

Use the javac program that comes with the JDK (visit java.sun.com if you don't have it). The installer does not automatically add javac to your system path, so you'll need to add the bin directory of the installed path to your system path before you can use it easily.

The Python standard library comes with an e-mail parsing function: email.utils.parseaddr().

It returns a two-tuple containing the real name and the actual address parts of the e-mail:

>>> from email.utils import parseaddr
>>> parseaddr('[email protected]')
('', '[email protected]')

>>> parseaddr('Full Name <[email protected]>')
('Full Name', '[email protected]')

>>> parseaddr('"Full Name with quotes and <[email protected]>" <[email protected]>')
('Full Name with quotes and <[email protected]>', '[email protected]')

And if the parsing is unsuccessful, it returns a two-tuple of empty strings:

>>> parseaddr('[invalid!email]')
('', '')

An issue with this parser is that it's accepting of anything that is considered as a valid e-mail address for RFC-822 and friends, including many things that are clearly not addressable on the wide Internet:

>>> parseaddr('invalid@example,com') # notice the comma
('', 'invalid@example')

>>> parseaddr('invalid-email')
('', 'invalid-email')

So, as @TokenMacGuy put it, the only definitive way of checking an e-mail address is to send an e-mail to the expected address and wait for the user to act on the information inside the message.

However, you might want to check for, at least, the presence of an @-sign on the second tuple element, as @bvukelic suggests:

>>> '@' in parseaddr("invalid-email")[1]
False

If you want to go a step further, you can install the dnspython project and resolve the mail servers for the e-mail domain (the part after the '@'), only trying to send an e-mail if there are actual MX servers:

>>> from dns.resolver import query
>>> domain = 'foo@[email protected]'.rsplit('@', 1)[-1]
>>> bool(query(domain, 'MX'))
True
>>> query('example.com', 'MX')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  [...]
dns.resolver.NoAnswer
>>> query('not-a-domain', 'MX')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  [...]
dns.resolver.NXDOMAIN

You can catch both NoAnswer and NXDOMAIN by catching dns.exception.DNSException.

And Yes, foo@[email protected] is a syntactically valid address. Only the last @ should be considered for detecting where the domain part starts.

Try this instead.

Using Ajax

Using the jQuery Ajax request method you can post the email data to a script (submit.php). Using the success callback option to animate elements after the script is executed.

note - I would suggest utilizing the ajax Response Object to make sure the script executed successfully.

$(function() {
    $('.submit').click(function() {
        $.ajax({
            type: 'POST',
            url: 'submit.php',
            data: 'password=p4ssw0rt',
            error: function()
            {
               alert("Request Failed");
            },
            success: function(response)
            {  
               //EXECUTE ANIMATION HERE
            } // this was missing
        });
        return false;
    }); 
})

::-webkit-scrollbar {
  display: none;
}

It will not work in Firefox, as the Firefox abandoned the support for hidden scrollbars with functionality (you can use overflow: -moz-scrollbars-none; in old versions).

You can see the history with git-reflog (example here):

From my understanding matplotlib is a plotting library.

If you want to change the image data (e.g. draw a rectangle on an image), you could use PIL's ImageDraw, OpenCV, or something similar.

Here is PIL's ImageDraw method to draw a rectangle.

Here is one of OpenCV's methods for drawing a rectangle.

Your question asked about Matplotlib, but probably should have just asked about drawing a rectangle on an image.

Here is another question which addresses what I think you wanted to know: Draw a rectangle and a text in it using PIL

I know this post is closed but I think my way could help some people. So there it is :

My dataset is very similar but is a bit more complex. It has numbers, alphanumeric data :

1
2
Chair 
3
0
4
5
-
Table
10
13
19
Windows
99
102
Dog

I would like to have the '-' symbol at first, then the numbers, then the text.

So I go like this :

SELECT name, (name = '-') boolDash, (name = '0') boolZero, (name+0 > 0) boolNum 
FROM table 
ORDER BY boolDash DESC, boolZero DESC, boolNum DESC, (name+0), name

The result should be something :

-
0    
1
2
3
4
5
10
13
99
102
Chair
Dog
Table
Windows

The whole idea is doing some simple check into the SELECT and sorting with the result.

you are almost there; you just need to give the reference to master; since you want to get the file from the master branch:

git checkout master -- filename

Note that the differences will be cached; so if you want to see the differences you obtained; use

git diff --cached

Your code is working fine using bootatrap v3.3.7, but you can use word-break: break-word if it's not working at your end.

which would then look like this -

In pyspark DOCS it would be subtract

df1.subtract(df2)

Here is a simple example:

EXEC sp_executesql @sql, N'@p1 INT, @p2 INT, @p3 INT', @p1, @p2, @p3;

Your call will be something like this

EXEC sp_executesql @statement, N'@LabID int, @BeginDate date, @EndDate date, @RequestTypeID varchar', @LabID, @BeginDate, @EndDate, @RequestTypeID

Function arguments may also be Arrays:

function foo([a,b,c], d){
  console.log(a,b,c,d);
}

foo([1,2,3], 4)

of-course one can also use spread:

function foo(a, b, c, d){
  console.log(a, b, c, d);
}

foo(...[1, 2, 3], 4)
