For me, I had a local branch named feature/phase2 and the remote branch was named feature/phase2/data-model. The naming conflict was the cause of the problem, so I deleted my local branch (you could rename it if it had anything you needed to keep)

Here's a script I used to batch import a bunch of crt files in the current directory into the java keystore. Just save this to the same folder as your certificate, and run it like so:

./import_all_certs.sh

import_all_certs.sh

KEYSTORE="$(/usr/libexec/java_home)/jre/lib/security/cacerts";

function running_as_root()
{
  if [ "$EUID" -ne 0 ]
    then echo "NO"
    exit
  fi

  echo "YES"
}

function import_certs_to_java_keystore
{
  for crt in *.crt; do 
    echo prepping $crt 
    keytool -import -file $crt -storepass changeit -noprompt --alias alias__${crt} -keystore $KEYSTORE
    echo 
  done
}

if [ "$(running_as_root)" == "YES" ]
then
  import_certs_to_java_keystore
else
  echo "This script needs to be run as root!"
fi

I want to indent a specific section of code in Visual Studio Code:

• Select the lines you want to indent, and
• use Ctrl + ] to indent them.

If you want to format a section (instead of indent it):

• Select the lines you want to format,
• use Ctrl + K, Ctrl + F to format them.

For folks that have programmed in nodeJs before, particularly using expressJS. I think of .ashx as a middleware that calls the next function. While .aspx will be the controller that actually responds to the request either around res.redirect, res.send or whatever.

Alternative to egaga's constructor method of copy. You probably already have a POJO, so just add another method copy() which returns a copy of the initialized object.

class DummyBean {
    private String dummyStr;
    private int dummyInt;

    public DummyBean(String dummyStr, int dummyInt) {
        this.dummyStr = dummyStr;
        this.dummyInt = dummyInt;
    }

    public DummyBean copy() {
        return new DummyBean(dummyStr, dummyInt);
    }

    //... Getters & Setters
}

If you already have a DummyBean and want a copy:

DummyBean bean1 = new DummyBean("peet", 2);
DummyBean bean2 = bean1.copy(); // <-- Create copy of bean1 

System.out.println("bean1: " + bean1.getDummyStr() + " " + bean1.getDummyInt());
System.out.println("bean2: " + bean2.getDummyStr() + " " + bean2.getDummyInt());

//Change bean1
bean1.setDummyStr("koos");
bean1.setDummyInt(88);

System.out.println("bean1: " + bean1.getDummyStr() + " " + bean1.getDummyInt());
System.out.println("bean2: " + bean2.getDummyStr() + " " + bean2.getDummyInt());

Output:

bean1: peet 2
bean2: peet 2

bean1: koos 88
bean2: peet 2

But both works well, it is ultimately up to you...

I had the same issue. I was using eclipse platform and server was missing in my show view. To fix this go:

• help>install new software

• in work with : select : "Indigo Update Site - http://download.eclipse.org/releases/indigo/" , once selected, all available software will be displayed in the section under type filter text

• Expand “Web, XML, and Java EE Development” and select "JST Server adapters extensions"

• then click next and finish. The server should be displayed in show view

Use the FileSystemObject object, namely, its CreateFolder and CopyFile methods. Basically, this is what your script will look like:

Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")

' Create a new folder
oFSO.CreateFolder "C:\MyFolder"

' Copy a file into the new folder
' Note that the destination folder path must end with a path separator (\)
oFSO.CopyFile "\\server\folder\file.ext", "C:\MyFolder\"

You may also want to add additional logic, like checking whether the folder you want to create already exists (because CreateFolder raises an error in this case) or specifying whether or not to overwrite the file being copied. So, you can end up with this:

Const strFolder = "C:\MyFolder\", strFile = "\\server\folder\file.ext"
Const Overwrite = True
Dim oFSO

Set oFSO = CreateObject("Scripting.FileSystemObject")

If Not oFSO.FolderExists(strFolder) Then
  oFSO.CreateFolder strFolder
End If

oFSO.CopyFile strFile, strFolder, Overwrite

This would be in addition to previous, if someone meets a problem with scandic letters that isn't solved with the solution above.

If the java source files contain scandic letters they need to be interpreted correctly by the Java used for compiling. (e.g. scandic letters used in constants)

Even that the files are stored in UTF-8 and the Maven is configured to use UTF-8, the System Java used by the Maven will still use the system default (eg. in Windows: cp1252).

This will be visible only running the tests via maven (possibly printing the values of these constants in tests. The printed scandic letters would show as '< ?>') If not tested properly, this would corrupt the class files as compile result and be left unnoticed.

To prevent this, you have to set the Java used for compiling to use UTF-8 encoding. It is not enough to have the encoding settings in the maven pom.xml, you need to set the environment variable: JAVA_TOOL_OPTIONS = -Dfile.encoding=UTF8

Also, if using Eclipse in Windows, you may need to set the encoding used in addition to this (if you run individual test via eclipse).

You need to use HttpContext.Current.Request.Cookies, not Response.Cookies.

Side note: cookies are copied to Request on Response.Cookies.Add, which makes check on either of them to behave the same for newly added cookies. But incoming cookies are never reflected in Response.

This behavior is documented in HttpResponse.Cookies property:

After you add a cookie by using the HttpResponse.Cookies collection, the cookie is immediately available in the HttpRequest.Cookies collection, even if the response has not been sent to the client.

I encountered a problem of taking integer input while solving a problem on CodeChef, where two integers - separated by space - should be read from one line.

While int(input()) is sufficient for a single integer, I did not find a direct way to input two integers. I tried this:

num = input()
num1 = 0
num2 = 0

for i in range(len(num)):
    if num[i] == ' ':
        break

num1 = int(num[:i])
num2 = int(num[i+1:])

Now I use num1 and num2 as integers. Hope this helps.

you can put

getchar();

before the return from the main function. That will wait for a character input before exiting the program.

Alternatively you could run your program from a command line and the output would be visible.

In Firefox, these function behave quite differently: log only prints out a toString representation, whereas dir prints out a navigable tree.

In Chrome, log already prints out a tree -- most of the time. However, Chrome's log still stringifies certain classes of objects, even if they have properties. Perhaps the clearest example of a difference is a regular expression:

> console.log(/foo/);
/foo/

> console.dir(/foo/);
* /foo/
    global: false
    ignoreCase: false
    lastIndex: 0
    ...

You can also see a clear difference with arrays (e.g., console.dir([1,2,3])) which are logged differently from normal objects:

> console.log([1,2,3])
[1, 2, 3]

> console.dir([1,2,3])
* Array[3]
    0: 1
    1: 2
    2: 3
    length: 3
    * __proto__: Array[0]
        concat: function concat() { [native code] }
        constructor: function Array() { [native code] }
        entries: function entries() { [native code] }
        ...

DOM objects also exhibit differing behavior, as noted on another answer.

It is a SELinux blocking issue, Linux prevented httpd access. Here is the solution:

# restorecon '/var/www/html/wiki/index.php'
# restorecon -R '/var/www/html/wiki/index.php'
# /sbin/restorecon '/var/www/html/wiki/index.php'

As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below

e.g.

Exec N'Select bla..' 

the N defines string literal is unicode.

You can use https://github.com/hughsk/flat

Take a nested Javascript object and flatten it, or unflatten an object with delimited keys.

Example from the doc

var flatten = require('flat')

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

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


var unflatten = require('flat').unflatten

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

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

An assertion Error is thrown when say "You have written a code that should not execute at all costs because according to you logic it should not happen. BUT if it happens then throw AssertionError. And you don't catch it." In such a case you throw an Assertion error.

new IllegalStateException("Must not instantiate an element of this class")' // Is an Exception not error.

Note: Assertion Error comes under java.lang.Error And Errors not meant to be caught.

Using Moment.js

If you have the option of including a third-party library, it's definitely worth taking a look at Moment.js. It makes working with Date and DateTime much, much easier.

For example, seeing if one Date comes after another Date but excluding their times, you would do something like this:

var date1 = new Date(2016,9,20,12,0,0); // October 20, 2016 12:00:00
var date2 = new Date(2016,9,20,12,1,0); // October 20, 2016 12:01:00

// Comparison including time.
moment(date2).isAfter(date1); // => true

// Comparison excluding time.
moment(date2).isAfter(date1, 'day'); // => false

The second parameter you pass into isAfter is the precision to do the comparison and can be any of year, month, week, day, hour, minute or second.

You can also use mvc frameworks like Backbone.js that will provide a javascript model of the data. Changes to the model will be translated into REST calls.

This is the proper way to access data in laravel :

@foreach($data-> ac as $link) 

   {{$link->url}}

@endforeach

There are lots of things I have seen make a model diverge.

1. Too high of a learning rate. You can often tell if this is the case if the loss begins to increase and then diverges to infinity.

2. I am not to familiar with the DNNClassifier but I am guessing it uses the categorical cross entropy cost function. This involves taking the log of the prediction which diverges as the prediction approaches zero. That is why people usually add a small epsilon value to the prediction to prevent this divergence. I am guessing the DNNClassifier probably does this or uses the tensorflow opp for it. Probably not the issue.

3. Other numerical stability issues can exist such as division by zero where adding the epsilon can help. Another less obvious one if the square root who's derivative can diverge if not properly simplified when dealing with finite precision numbers. Yet again I doubt this is the issue in the case of the DNNClassifier.

4. You may have an issue with the input data. Try calling assert not np.any(np.isnan(x)) on the input data to make sure you are not introducing the nan. Also make sure all of the target values are valid. Finally, make sure the data is properly normalized. You probably want to have the pixels in the range [-1, 1] and not [0, 255].

5. The labels must be in the domain of the loss function, so if using a logarithmic-based loss function all labels must be non-negative (as noted by evan pu and the comments below).

$url = 'http://legis.senado.leg.br/dadosabertos/materia/tramitando';
$xml = file_get_contents("xml->{$url}");
$xml = simplexml_load_file($url);

I'm using SSMS 2008 version 10.0.5500.0. In this version as part of the Generate Scripts wizard, instead of an Advanced button, there is the screen below. In this case, I wanted just the data inserted and no create statements, so I had to change the two circled properties

Yet another one (I prefer Mark Longair's answer)

di = {'a':1,'b':2,'c':3}
req = ['a','c','w']
dict([i for i in di.iteritems() if i[0] in di and i[0] in req])

IE works with iframe like all the other browsers (at least for main functions). You just have to keep a set of rules:

• before you load any javascript in the iframe (that part of js which needs to know about the iframe parent), ensure that the parent has document.domain changed.

• when all iframe resources are loaded, change document.domain to be the same as the one defined in parent. (You need to do this later because setting domain will cause the iframe resource's request to fail)

• now you can make a reference for parent window: var winn = window.parent

• now you can make a reference to parent HTML, in order to manipulate it: var parentContent = $('html', winn.document)
• at this point you should have access to IE parent window/document and you can change it as you wont

Similar to getting the length of a dataframe, len(df), the following worked for pandas and blaze:

Total = sum(df['MyColumn'])

or alternatively

Total = sum(df.MyColumn)
print Total

I use this solution on my website. If $str is shorter, than $max, it will remain unchanged. If $str has no spaces among first $max characters, it will be brutally cut at $max position. Otherwise 3 dots will be added after the last whole word.

function short_str($str, $max = 50) {
    $str = trim($str);
    if (strlen($str) > $max) {
        $s_pos = strpos($str, ' ');
        $cut = $s_pos === false || $s_pos > $max;
        $str = wordwrap($str, $max, ';;', $cut);
        $str = explode(';;', $str);
        $str = $str[0] . '...';
    }
    return $str;
}

Below applies to all tags with the following two classes

.abc.xyz {  
  width: 200px !important;
}

applies to div tags with the following two classes

div.abc.xyz {  
  width: 200px !important;
}

If you wanted to modify this using jQuery

$(document).ready(function() {
  $("div.abc.xyz").width("200px");
});

Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

Here's yet another solution, just for kicks. It's probably not very efficient, but it does cope with both height and width of the text, and with marked-up text.

@Override
protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec)
{
    if ((MeasureSpec.getMode(widthMeasureSpec) != MeasureSpec.UNSPECIFIED)
            && (MeasureSpec.getMode(heightMeasureSpec) != MeasureSpec.UNSPECIFIED)) {

        final float desiredWidth = MeasureSpec.getSize(widthMeasureSpec);
        final float desiredHeight = MeasureSpec.getSize(heightMeasureSpec);

        float textSize = getTextSize();
        float lastScale = Float.NEGATIVE_INFINITY;
        while (textSize > MINIMUM_AUTO_TEXT_SIZE_PX) {
            // Measure how big the textview would like to be with the current text size.
            super.onMeasure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);

            // Calculate how much we'd need to scale it to fit the desired size, and
            // apply that scaling to the text size as an estimate of what we need.
            final float widthScale = desiredWidth / getMeasuredWidth();
            final float heightScale = desiredHeight / getMeasuredHeight();
            final float scale = Math.min(widthScale, heightScale);

            // If we don't need to shrink the text, or we don't seem to be converging, we're done.
            if ((scale >= 1f) || (scale <= lastScale)) {
                break;
            }

            // Shrink the text size and keep trying.
            textSize = Math.max((float) Math.floor(scale * textSize), MINIMUM_AUTO_TEXT_SIZE_PX);
            setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);
            lastScale = scale;
        }
    }
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

As of IE11, you need to use addEventListener. attachEvent is deprecated and throws an error.

If this SQL is being used in any peoplesoft specific code (Application Engine, SQLEXEC, SQLfetch, etc..) you could use %Datein metaSQL. Peopletools automatically converts the date to a format which would be accepted by the database platform the application is running on.

In case this SQL is being used to perform a backend update from a query analyzer (like SQLDeveloper, SQLTools), the date format that is being used is wrong. Oracle expects the date format to be DD-MMM-YYYY, where MMM could be JAN, FEB, MAR, etc..

freopen solves the easy part. Keeping old stdin around is not hard if you haven't read anything and if you're willing to use POSIX system calls like dup or dup2. If you're started to read from it, all bets are off.

Maybe you can tell us the context in which this problem occurs?

I'd encourage you to stick to situations where you're willing to abandon old stdin and stdout and can therefore use freopen.

It is easy if you are using django version 3.1 and above

def login_view(request):
    if(request.POST):
        yourForm= YourForm(request.POST)
        itemValue = yourForm['your_filed_name'].value()
        # Check if you get the value
        return HttpResponse(itemValue )
    else:
        return render(request, "base.html")

The code

my_list = [(1, 2), (3, 4), (5, 6)]
for t in my_list:
    print t

prints

(1, 2)
(3, 4)
(5, 6)

The loop iterates over my_list, and assigns the elements of my_list to t one after the other. The elements of my_list happen to be tuples, so t will always be a tuple. To access the first element of the tuple t, use t[0]:

for t in my_list:
    print t[0]

To access the first element of the tuple at the given index i in the list, you can use

print my_list[i][0]

The answer given by @ravi-luthra technically works but it has some issues!

In my case, I was just trying to recover disk space. The lib/docker/overlay folder was taking 30GB of space and I only run a few containers regularly. Looks like docker has some issue with data leakage and some of the temporary data are not cleared when the container stops.

So I went ahead and deleted all the contents of lib/docker/overlay folder. After that, My docker instance became un-useable. When I tried to run or build any container, It gave me this error:

failed to create rwlayer: symlink ../04578d9f8e428b693174c6eb9a80111c907724cc22129761ce14a4c8cb4f1d7c/diff /var/lib/docker/overlay2/l/C3F33OLORAASNIYB3ZDATH2HJ7: no such file or directory

Then with some trial and error, I solved this issue by running

(WARNING: This will delete all your data inside docker volumes)

docker system prune --volumes -a

So It is not recommended to do such dirty clean ups unless you completely understand how the system works.

urllib went through some changes in Python3 and can now be imported from the parse submodule

>>> from urllib.parse import quote

I had a similar issue, CMake finding a vendor-installed Boost only, but my cluster had a locally installed version which is what I wanted it to use. Red Hat Linux 6.

Anyway, it looks like all the BOOSTROOT, BOOST_ROOT, and Boost_DIR stuff would get annoyed unless one also sets Boost_NO_BOOST_CMAKE (e.g add to cmd line -DBoost_NO_BOOST_CMAKE=TRUE).

(I will concede the usefulness of CMake for multiplatform, but I can still hate it.)

Try this:

_imageView.image = image;
[_imageView.layer addAnimation:[CATransition animation] forKey:kCATransition];

You can change project facet from Project --> Properties --> Project Facet --> Java --> {required JDK version}

based on Sam Holder's answer, you could make an extension method for that

namespace adonet.extensions
{
  public static class AdonetExt
  {
    public static int GetInt32(this SqlDataReader reader, string columnName)
    {
      return reader.GetInt32(reader.GetOrdinal(columnName));
    }
  }
}

and use it like this

using adonet.extensions;

//...

int farmsize = reader.GetInt32("farmsize");

assuming there is no GetInt32(string) already in SqlDataReader - if there is any, just use some other method name instead

Application server and web server both are used to host web application. Web Server is deal with web container on the other hand Application Server is deal with web container as well as EJB (Enterprise JavaBean) container or COM+ container for Microsoft dot Net.

Web Server is designed to serve HTTP static Content like HTML, images etc. and for the dynamic content have plugins to support scripting languages like Perl, PHP, ASP, JSP etc and it is limited to HTTP protocol. Below servers can generate dynamic HTTP content.

Web Server's Programming Environment:

IIS : ASP (.NET)

Apache Tomcat: Servlet

Jetty: Servlet

Apache: Php, CGI

Application Server can do whatever Web Server is capable and listens using any protocol as well as App Server have components and features to support Application level services such as Connection Pooling, Object Pooling, Transaction Support, Messaging services etc.

Application Server's Programming Environment:

MTS: COM+

WAS: EJB

JBoss: EJB

WebLogic Application Server: EJB

I can offer you a jquery solution

add this in your <head></head> tag

add this after </ul>

 <script> $('ul li:first').remove(); </script> 

A new approach based on the previous example function submited by chaos, which fixes the bug of overwritting string keys in multiarrays:

# Flatten a multidimensional array to one dimension, optionally preserving keys.
# $array - the array to flatten
# $preserve_keys - 0 (default) to not preserve keys, 1 to preserve string keys only, 2 to preserve all keys
# $out - internal use argument for recursion

function flatten_array($array, $preserve_keys = 2, &$out = array(), &$last_subarray_found) 
{
        foreach($array as $key => $child)
        {
            if(is_array($child))
            {
                $last_subarray_found = $key;
                $out = flatten_array($child, $preserve_keys, $out, $last_subarray_found);
            }
            elseif($preserve_keys + is_string($key) > 1)
            {
                if ($last_subarray_found)
                {
                    $sfinal_key_value = $last_subarray_found . "_" . $key;
                }
                else
                {
                    $sfinal_key_value = $key;
                }
                $out[$sfinal_key_value] = $child;
            }
            else
            {
                $out[] = $child;
            }
        }

        return $out;
}

Example:
$newarraytest = array();
$last_subarray_found = "";
$this->flatten_array($array, 2, $newarraytest, $last_subarray_found);

png has a wider color pallete than gif and gif is properitary while png is not. gif can do animations, what normal-png cannot. png-transparency is only supported by browser roughly more recent than IE6, but there is a Javascript fix for that problem. Both support alpha transparency. In general I would say that you should use png for most webgraphics while using jpeg for photos, screenshots, or similiar because png compression does not work too good on thoose.

Hey there just ran into the same issue you did, the 3rd link down in google brought me to this bit of code that throws the error,

if (kernelFile == NULL) {
        kernelFile = avdInfo_getKernelPath(avd);
        if (kernelFile == NULL) {

So I went back in and downloaded the x86 intel atom version for my desired API level and was able to get the emulator up without the error. Hope it helps you too.....

I assume you're on Vista using VS2008? In that case I think that the FOS_PICKFOLDERS option is being used when calling the Vista file dialog IFileDialog. I'm afraid that in .NET code this would involve plenty of gnarly P/Invoke interop code to get working.

You want this

document.body.insertAdjacentHTML( 'afterbegin', '<div id="myID">...</div>' );

I noticed that when it's set to false, I'm able to see the value of an item using the debugger. When it was set to true, I was getting an error - item.FullName.GetValue The embedded interop type 'FullName' does not contain a definition for 'QBFC11Lib.IItemInventoryRet' since it was not used in the compiled assembly. Consider casting to object or changing the 'Embed Interop Types' property to true.

You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.

The problem in my case was that the "receiver mountpoint" was incorrectly mounted. It was in read-only mode (for some extrange reason). It looked like rsync was copying the files, but it was not. I checked my fstab file and changed mount options to default, re-mount file system and execute rsync again. All fine then.

It should be the same command, except SET instead of EXPORT

• set MAVEN_OPTS=-Xmx512m would give it 512Mb of heap
• set MAVEN_OPTS=-Xmx2048m would give it 2Gb of heap

This worked for me

sudo apt-get install ca-certificates

then go into the certificates folder at

sudo cd /etc/ssl/certs

then you copy the ca-certificates.crt file into the /etc/pki/tls/certs

sudo cp ca-certificates.crt /etc/pki/tls/certs

if there is no tls/certs folder: create one and change permissions using chmod 777 -R folderNAME

You can tweak the Registry if you want to make changes only to your own system. If you have IE10 and lots of web sites you visit don't render properly in IE10, then you can tweak your registry to force IE to open in IE9 mode.

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

Create a DWORD as iexplore.exe and give value 9999. Restart your IE and it will open in IE9 mode :)

Thanks to my colleague Sreejith D :)

The dword ptr part is called a size directive. This page explains them, but it wasn't possible to direct-link to the correct section.

Basically, it means "the size of the target operand is 32 bits", so this will bitwise-AND the 32-bit value at the address computed by taking the contents of the ebp register and subtracting four with 0.

Yet another custom implementation that doesn't require support table:

You should convert charset after decoding: convert(base64_decode(base64_encode('????')) using utf8)

You can use the following formula,

=IF(ISTEXT(REGEXEXTRACT(A1; "Bla")); "Yes";"No")

FYI, I've got the same error from Chrome console. I thought my AJAX function causing it, but I uncommented my minified script from /javascripts/ajax-vanilla.min.js to /javascripts/ajax-vanilla.js. But in reality the source file was at /javascripts/src/ajax-vanilla.js. So in Chrome you getting bad MIME type error even if the file cannot be found. In this case, the error message is described as text/plain bad MIME type.

Three Step Process: First: open Terminal->$ whereis java it would give output like this: java: /usr/bin/java /usr/share/java /usr/share/man/man1/java.1.gz

Second: ls -l /usr/bin/java It would give output like this: lrwxrwxrwx 1 root root 22 Feb 9 10:59 /usr/bin/java -> /etc/alternatives/java

Third: ls -l /etc/alternatives/java output is the JDK path: lrwxrwxrwx 1 root root 46 Feb 9 10:59 /etc/alternatives/java -> /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

double d = 14.4;
if((d-(int)d)!=0)
    System.out.println("decimal value is there");
else
    System.out.println("decimal value is not there");

I would suggest following extension methods for string parsing into int value with ability to define default value in case parsing is not possible:

public static int ParseInt(this string value, int defaultIntValue = 0)
        {
            return int.TryParse(value, out var parsedInt) ? parsedInt : defaultIntValue;
        }

public static int? ParseNullableInt(this string value)
        {
            if (string.IsNullOrEmpty(value))
                return null;

            return value.ParseInt();
        }

You cannot use WHILE like that; see: mysql DECLARE WHILE outside stored procedure how?

You have to put your code in a stored procedure. Example:

CREATE PROCEDURE myproc()
BEGIN
    DECLARE i int DEFAULT 237692001;
    WHILE i <= 237692004 DO
        INSERT INTO mytable (code, active, total) VALUES (i, 1, 1);
        SET i = i + 1;
    END WHILE;
END

Fiddle: http://sqlfiddle.com/#!2/a4f92/1

Alternatively, generate a list of INSERT statements using any programming language you like; for a one-time creation, it should be fine. As an example, here's a Bash one-liner:

for i in {2376921001..2376921099}; do echo "INSERT INTO mytable (code, active, total) VALUES ($i, 1, 1);"; done

By the way, you made a typo in your numbers; 2376921001 has 10 digits, 237692200 only 9.

If you do not want to define a separate class for nested json , Defining nested json object as JsonNode should work ,for example :

{"id":2,"socket":"0c317829-69bf-43d6-b598-7c0c550635bb","type":"getDashboard","data":{"workstationUuid":"ddec1caa-a97f-4922-833f-632da07ffc11"},"reply":true}

@JsonProperty("data")
    private JsonNode data;

Second Thomas David Kehoe, with the following caveat --

If you are using node version manager (nvm), your global node modules will be stored under whatever version of node you are using at the time you saved the module.

So ~/.nvm/versions/node/{version}/lib/node_modules/.

For examle we have two lists:

  public static void main(String[] args) {
        ArrayList a = new ArrayList(Arrays.asList(new String[]{"a1", "a2", "a3","a4", "a5"}));
        ArrayList b = new ArrayList(Arrays.asList(new String[]{"b1", "b2", "b3","b4", "b5"}));
        merge(a, b);
        a.stream().map( x -> x + " ").forEach(System.out::print);
    }
   public static void merge(List a, List b){
        for (Iterator itb = b.iterator(); itb.hasNext(); ){
            for (ListIterator it = a.listIterator() ; it.hasNext() ; ){
                it.next();
                it.add(itb.next());

            }
        }

    }

a1 b1 a2 b2 a3 b3 a4 b4 a5 b5

Create a class in your CSS file:

.active {
  z-index: 20;
  background: rgb(23,55,94)
  color: #fff;
}

Then in your jQuery

$(this).addClass("active");

I'm unable to reproduce your problem but have you tried converting it to an integer first?

image_name_data['id'] = image_name_data['id'].astype(int).astype('str')

Then, regarding your more general question you could use map (as in this answer). In your case:

image_name_data['id'] = image_name_data['id'].map('{:.0f}'.format)

There isn't much else to add other than what the docs say. If you want to dump the JSON into a file/socket or whatever, then you should go with dump(). If you only need it as a string (for printing, parsing or whatever) then use dumps() (dump string)

As mentioned by Antti Haapala in this answer, there are some minor differences on the ensure_ascii behaviour. This is mostly due to how the underlying write() function works, being that it operates on chunks rather than the whole string. Check his answer for more details on that.

json.dump()

Serialize obj as a JSON formatted stream to fp (a .write()-supporting file-like object

If ensure_ascii is False, some chunks written to fp may be unicode instances

json.dumps()

Serialize obj to a JSON formatted str

If ensure_ascii is False, the result may contain non-ASCII characters and the return value may be a unicode instance

Update MyTable
Set Value = (
                Select Min( T2.Value )
                From MyTable As T2
                Where T2.Id <> MyTable.Id
                    And T2.Name = MyTable.Name
                )
Where ( Value Is Null Or Value = '' )
    And Exists  (
                Select 1
                From MyTable As T3
                Where T3.Id <> MyTable.Id
                    And T3.Name = MyTable.Name
                )

Using timestamp...

<?php
if (!isset($_SESSION)) {
    $session = session_start();
} 
if ($session && !isset($_SESSION['login_time'])) {
    if ($session == 1) {
        $_SESSION['login_time']=time();
        echo "Login :".$_SESSION['login_time'];
        echo "<br>";
        $_SESSION['idle_time']=$_SESSION['login_time']+20;
        echo "Session Idle :".$_SESSION['idle_time'];
        echo "<br>";
    } else{
        $_SESSION['login_time']="";
    }
} else {
    if (time()>$_SESSION['idle_time']){
        echo "Session Idle :".$_SESSION['idle_time'];
        echo "<br>";
        echo "Current :".time();
        echo "<br>";
        echo "Session Time Out";
        session_destroy();
        session_unset();
    } else {
        echo "Logged In<br>";
    }
}
?>

I have used 20 seconds to expire the session using timestamp.

If you need 30 min add 1800 (30 min in seconds)...

Solution in ES6/TypeScript:

let d = new Date;
console.log(d, [`${d.getFullYear()}`, `0${d.getMonth()}`.substr(-2), `0${d.getDate()}`.substr(-2)].join("-"));

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

Yes, should try reinstall mysql, but use the --reinstall flag to force a package reconfiguration. So the operating system service configuration is not skipped:

sudo apt --reinstall install mysql-server

Try an LL suffix on the number, the compiler may be casting it to an intermediate type as part of the parse. See http://gcc.gnu.org/onlinedocs/gcc/Long-Long.html

long long int i2 = 0x0000444400004444LL;

Additionally, the the compiler is discarding the leading zeros, so 0x000044440000 is becoming 0x44440000, which is a perfectly acceptable 32-bit integer (which is why you aren't seeing any warnings prior to f2).

What is the way to generate a patch only for the specific SHA1?

It's quite simple:

Option 1. git show commitID > myFile.patch

Option 2. git commitID~1..commitID > myFile.patch

Note: Replace commitID with actual commit id (SHA1 commit code).

Adjusted to allow for daylight saving differences. try this:

  function daysBetween(date1, date2) {

 // adjust diff for for daylight savings
 var hoursToAdjust = Math.abs(date1.getTimezoneOffset() /60) - Math.abs(date2.getTimezoneOffset() /60);
 // apply the tz offset
 date2.addHours(hoursToAdjust); 

    // The number of milliseconds in one day
    var ONE_DAY = 1000 * 60 * 60 * 24

    // Convert both dates to milliseconds
    var date1_ms = date1.getTime()
    var date2_ms = date2.getTime()

    // Calculate the difference in milliseconds
    var difference_ms = Math.abs(date1_ms - date2_ms)

    // Convert back to days and return
    return Math.round(difference_ms/ONE_DAY)

}

// you'll want this addHours function too 

Date.prototype.addHours= function(h){
    this.setHours(this.getHours()+h);
    return this;
}

Another solution:

public class CountryInfoResponse {
  private List<Object> geonames;
}

Usage of a generic Object-List solved my problem, as there were other Datatypes like Boolean too.

$(document).ready(function () {



    $("#cust_zip").keypress(function (e) {
        //var z = document.createUserForm.cust_mobile1.value;
        //alert(z);
        if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) {

            $("#errmsgzip").html("Digits Only.").show().fadeOut(3000);
            return false;
        }
    });
});

Using the Apache Commons IO API https://commons.apache.org/proper/commons-io/ I was able to establish this using FileUtils.readFileToString(file).contains(stringToFind)

You should not attempt to parse HTML with regex. HTML is not a regular language, so any regex you come up with will likely fail on some esoteric edge case. Please refer to the seminal answer to this question for specifics. While mostly formatted as a joke, it makes a very good point.

The following examples are Java, but the regex will be similar -- if not identical -- for other languages.

String target = someString.replaceAll("<[^>]*>", "");

Assuming your non-html does not contain any < or > and that your input string is correctly structured.

If you know they're a specific tag -- for example you know the text contains only <td> tags, you could do something like this:

String target = someString.replaceAll("(?i)<td[^>]*>", "");

Edit: Omega brought up a good point in a comment on another post that this would result in multiple results all being squished together if there were multiple tags.

For example, if the input string were <td>Something</td><td>Another Thing</td>, then the above would result in SomethingAnother Thing.

In a situation where multiple tags are expected, we could do something like:

String target = someString.replaceAll("(?i)<td[^>]*>", " ").replaceAll("\\s+", " ").trim();

This replaces the HTML with a single space, then collapses whitespace, and then trims any on the ends.

*In all instances the # refers to the cell number

You really don't need the datedif functions; for example:

I'm working on a spreadsheet that tracks benefit eligibility for employees.

I have their hire dates in the "A" column and in column B is =(TODAY()-A#)

And you just format the cell to display a general number instead of date.

It also works very easily the other way: I also converted that number into showing when the actual date is that they get their benefits instead of how many days are left, and that is simply

=(90-B#)+TODAY()

Just make sure you're formatting cells as general numbers or dates accordingly.

Hope this helps.

At first check the file address, it must be beside your .java file or in any address that you define in classpath environment variable. When you check this then try below.

1. you must use a file name by it's extension in File object constructor, as an example:

   File myFile = new File("test.txt");

2. but there is a better way to use it inside Scanner object by pass the filename absolute address, as an example:

   Scanner sc = new Scanner(Paths.get("test.txt"));

in this way you must import java.nio.file.Paths as well.

The way I like, is if you have a date object you can subtract another date object from it to get the difference. Date objects are based on milliseconds from a certain date.

var date1 = new Date(2015, 02, 18); // "18/03/2015", month is 0-index
var date2 = new Date(2015, 02, 20); // "20/03/2015"

var msDiff = date2 - date1; // 172800000, this is time in milliseconds
var daysDiff = msDiff / 1000 / 60 / 60 / 24; // 2 days

So this is how you subtract dates. Now if you want to add them? date1 + date2 gives an error.. But if I want to get the time in ms I can use:

var dateMs = date1 - 0;
// say I want to add 5 days I can use
var days = 5;
var msToAdd = days * 24 * 60 * 60 * 1000; 
var newDate = new Date(dateMs + msToAdd);

By subtracting 0 you turn the date object into the milliseconds format.

Use 404 if the resource does not exist. Don't return 200 with an empty body.

This is akin to undefined vs empty string (e.g. "") in programming. While very similar, there is definitely a difference.

404 means that nothing exists at that URI (like an undefined variable in programming). Returning 200 with an empty body means that something does exist there and that something is just empty right now (like an empty string in programming).

404 doesn't mean it was a "bad URI". There are special HTTP codes that are intended for URI errors (e.g. 414 Request-URI Too Long).

Bogobogosort. Yes, it's a thing. to Bogobogosort, you Bogosort the first element. Check to see if that one element is sorted. Being one element, it will be. Then you add the second element, and Bogosort those two until it's sorted. Then you add one more element, then Bogosort. Continue adding elements and Bogosorting until you have finally done every element. This was designed never to succeed with any sizable list before the heat death of the universe.

I have found that a button works, but that you'll want to add style="height: 100%;" to the button so that it will show more than the first line on Safari for iPhone iOS 5.1.1

Something I recently discovered for styling Radio Buttons AND Checkboxes. Before, I had to use jQuery and other things. But this is stupidly simple.

input[type=radio] {
    padding-left:5px;
    padding-right:5px;
    border-radius:15px;

    -webkit-appearance:button;

    border: double 2px #00F;

    background-color:#0b0095;
    color:#FFF;
    white-space: nowrap;
    overflow:hidden;

    width:15px;
    height:15px;
}

input[type=radio]:checked {
    background-color:#000;
    border-left-color:#06F;
    border-right-color:#06F;
}

input[type=radio]:hover {
    box-shadow:0px 0px 10px #1300ff;
}

You can do the same for a checkbox, obviously change the input[type=radio] to input[type=checkbox] and change border-radius:15px; to border-radius:4px;.

Hope this is somewhat useful to you.

In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.

But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:

{ Id: 1, 
name:'john', 
phones:[{title:'home',number:111111,...},
        {title:'office',number:22222,...}]
}

sends

{ Id: 1, 
name:'john', 
phones:[object object]
phones:[object object]
}

Here's how to do it in Swift

Changes for Swift 3.0:

• NSPipe has been renamed Pipe

• NSTask has been renamed Process

This is based on inkit's Objective-C answer above. He wrote it as a category on NSString — For Swift, it becomes an extension of String.

extension  String.runAsCommand()  ->  String

extension String {
    func runAsCommand() -> String {
        let pipe = Pipe()
        let task = Process()
        task.launchPath = "/bin/sh"
        task.arguments = ["-c", String(format:"%@", self)]
        task.standardOutput = pipe
        let file = pipe.fileHandleForReading
        task.launch()
        if let result = NSString(data: file.readDataToEndOfFile(), encoding: String.Encoding.utf8.rawValue) {
            return result as String
        }
        else {
            return "--- Error running command - Unable to initialize string from file data ---"
        }
    }
}

Usage:

let input = "echo hello"
let output = input.runAsCommand()
print(output)                        // prints "hello"

    or just:

print("echo hello".runAsCommand())   // prints "hello" 

Example:

@IBAction func toggleFinderShowAllFiles(_ sender: AnyObject) {

    var newSetting = ""
    let readDefaultsCommand = "defaults read com.apple.finder AppleShowAllFiles"

    let oldSetting = readDefaultsCommand.runAsCommand()

    // Note: the Command results are terminated with a newline character

    if (oldSetting == "0\n") { newSetting = "1" }
    else { newSetting = "0" }

    let writeDefaultsCommand = "defaults write com.apple.finder AppleShowAllFiles \(newSetting) ; killall Finder"

    _ = writeDefaultsCommand.runAsCommand()

}

Note the Process result as read from the Pipe is an NSString object. It might be an error string and it can also be an empty string, but it should always be an NSString.

So, as long as it's not nil, the result can cast as a Swift String and returned.

If for some reason no NSString at all can be initialized from the file data, the function returns an error message. The function could have been written to return an optional String?, but that would be awkward to use and wouldn't serve a useful purpose because it's so unlikely for this to occur.

If you meant to run foo() inside a python script every 10 seconds, you can do something on these lines.

import time

def foo():
    print "Howdy"

while True:
    foo()
    time.sleep(10)

May not be related to the question here. But I found it could be useful when using ROW_NUMBER -

SELECT *,
ROW_NUMBER() OVER (ORDER BY (SELECT 100)) AS Any_ID 
FROM #Any_Table

I've used sliksvn and it works great for me

declare @LkeVal as Varchar(100)
declare @LkeSelect Varchar(100)

Set @LkeSelect = (select top 1 <column> from <table> where <column> = 'value')
Set @LkeVal = '%' + @LkeSelect

select * from <table2> where <column2> like(''+@LkeVal+'');

Like you, I was also looking for a solution which does not include newlines. (While they may be safe in SQL, they're not safe in my case and I have a large block of text to deal with)

This is arguably just as ugly, but you can backslash-escape newlines in a heredoc to omit them from the resulting string:

conn.exec <<~END_OF_INPUT
    select attr1, attr2, attr3, attr4, attr5, attr6, attr7 \
    from table1, table2, table3, etc, etc, etc, etc, etc, \
    where etc etc etc etc etc etc etc etc etc etc etc etc etc
  END_OF_INPUT

Note that you cannot due this without interpolation (I.E. <<~'END_OF_INPUT') so be careful. #{expressions} will be evaluated here, whereas they will not in your original code. A. Wilson's answer may be better for that reason.

".*[^(\\.inc)]\\.ftl$"

In Java this will find all files ending in ".ftl" but not ending in ".inc.ftl", which is exactly what I wanted.

I think this is no longer available due to 'security issues'.

console.log(console) from code gives:

Console
memory: MemoryInfo
profiles: Array[0]
__proto__: Console

From outside of code, _commandLineAPI is available. Kind of annoying because sometimes I want to just log and not see the old output.

    ## Working with buffered content
    tmp = data["location"] 
    data["location"] = path
    data["mode"] = "replay"

    ## Save our changes to JSON file
    jsonFile = open("replayScript.json", "w+")
    jsonFile.write(json.dumps(data))
    jsonFile.close()

I had a similar problem:

module cv2 has no attribute "cv2.TrackerCSRT_create"

My Python version is 3.8.0 under Windows 10. The problem was the opencv version installation.

So I fixed this way (cmd prompt with administrator privileges):

1. Uninstalled opencv-python: pip uninstall opencv-python
2. Installed only opencv-contrib-python: pip install opencv-contrib-python

Anyway you can read the following guide:

https://github.com/skvark/opencv-python

$('.second').find('div:first')

This could also be a solution without having to introduce a new method:

    item = collection["item"] != null ? collection["item"].ToString() : null;

Don't loop through a file this way. Instead use a for loop.

for line in f:
    vowel += sum(ch.isvowel() for ch in line)

In fact your whole program is just:

VOWELS = {'A','E','I','O','U','a','e','i','o','u'}
# I'm assuming this is what isvowel checks, unless you're doing something
# fancy to check if 'y' is a vowel
with open('filename.txt') as f:
    vowel = sum(ch in VOWELS for line in f for ch in line.strip())

That said, if you really want to keep using a while loop for some misguided reason:

while True:
    line = f.readline().strip()
    if line == '':
        # either end of file or just a blank line.....
        # we'll assume EOF, because we don't have a choice with the while loop!
        break

1 ) Copy the initialAdminPassword in Specified path.

2 ) Login with following Credentials

3 ) Once you login into the jenkins application you can click on admin profile and reset the password.

There is no such thing as "SOAP protocol". SOAP is an XML schema.

It usually runs over HTTP (port 80), however.

If someone is looking for another option for Git Lab and the options above do not work, then we have another option. For a local installation of Git Lab server, we have found that the approach, below, allows us to include the package dependency. We generated and use an access token to do so.

$ npm install --save-dev https://git.yourdomain.com/userOrGroup/gitLabProjectName/repository/archive.tar.gz?private_token=InsertYourAccessTokenHere

Of course, if one is using an access key this way, it should have a limited set of permissions.

Good luck!

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

Before answering, let's add some background, explaining what this HEAD is.

First of all what is HEAD?

HEAD is simply a reference to the current commit (latest) on the current branch.
There can only be a single HEAD at any given time (excluding git worktree).

The content of HEAD is stored inside .git/HEAD and it contains the 40 bytes SHA-1 of the current commit.

detached HEAD

If you are not on the latest commit - meaning that HEAD is pointing to a prior commit in history it's called detached HEAD.

On the command line, it will look like this - SHA-1 instead of the branch name since the HEAD is not pointing to the tip of the current branch:

A few options on how to recover from a detached HEAD:

git checkout

git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits t go back

This will checkout new branch pointing to the desired commit.
This command will checkout to a given commit.
At this point, you can create a branch and start to work from this point on.

# Checkout a given commit.
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>

# Create a new branch forked to the given commit
git checkout -b <branch name>

git reflog

You can always use the reflog as well.
git reflog will display any change which updated the HEAD and checking out the desired reflog entry will set the HEAD back to this commit.

Every time the HEAD is modified there will be a new entry in the reflog

git reflog
git checkout HEAD@{...}

This will get you back to your desired commit

git reset --hard <commit_id>

"Move" your HEAD back to the desired commit.

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts if you've modified things which were
# changed since the commit you reset to.

• Note: (Since Git 2.7) you can also use the git rebase --no-autostash as well.

git revert <sha-1>

"Undo" the given commit or commit range.
The reset command will "undo" any changes made in the given commit.
A new commit with the undo patch will be committed while the original commit will remain in the history as well.

# Add a new commit with the undo of the original one.
# The <sha-1> can be any commit(s) or commit range
git revert <sha-1>

This schema illustrates which command does what.
As you can see there, reset && checkout modify the HEAD.

Java 8 with apache httpClient 4

CloseableHttpClient client = HttpClientBuilder.create().build();
HttpPost httpPost = new HttpPost("www.site.com");


String json = "details={\"name\":\"myname\",\"age\":\"20\"} ";

        try {
            StringEntity entity = new StringEntity(json);
            httpPost.setEntity(entity);

            // set your POST request headers to accept json contents
            httpPost.setHeader("Accept", "application/json");
            httpPost.setHeader("Content-type", "application/json");

            try {
                // your closeablehttp response
                CloseableHttpResponse response = client.execute(httpPost);

                // print your status code from the response
                System.out.println(response.getStatusLine().getStatusCode());

                // take the response body as a json formatted string 
                String responseJSON = EntityUtils.toString(response.getEntity());

                // convert/parse the json formatted string to a json object
                JSONObject jobj = new JSONObject(responseJSON);

                //print your response body that formatted into json
                System.out.println(jobj);

            } catch (IOException e) {
                e.printStackTrace();
            } catch (JSONException e) {

                e.printStackTrace();
            }

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }

You can try the some thing like the below LINQ snippet.

string[] allLines = File.ReadAllLines(@"E:\Temp\data.csv");

    var query = from line in allLines
                let data = line.Split(',')
                select new
                {
                    Device = data[0],
                    SignalStrength = data[1],
                    Location = data[2], 
                    Time = data[3],
                    Age = Convert.ToInt16(data[4])
                };

UPDATE: Over a period of time, things evolved. As of now, I would prefer to use this library http://www.aspnetperformance.com/post/LINQ-to-CSV-library.aspx

Set the path JAVA_HOME and ANDROID_HOME > You have to open terminal and enter the below cmd.

touch ~/.bash_profile; open ~/.bash_profile

After that paste below paths in base profile file and save it

export ANDROID_HOME=/Users/<username>/Library/Android/sdk 
export PATH="$JAVA_HOME/bin:$ANDROID_HOME/platform-tools:$ANDROID_HOME/emulator:$PATH"
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home

For #outer height to be based on its content, and have #inner base its height on that, make both elements absolutely positioned.

More details can be found in the spec for the css height property, but essentially, #inner must ignore #outer height if #outer's height is auto, unless #outer is positioned absolutely. Then #inner height will be 0, unless #inner itself is positioned absolutely.

<style>
    #outer {
        position:absolute; 
        height:auto; width:200px; 
        border: 1px solid red; 
    }
    #inner {
        position:absolute; 
        height:100%; 
        width:20px; 
        border: 1px solid black; 
    }
</style>

<div id='outer'>
    <div id='inner'>
    </div>
    text
</div>

However... By positioning #inner absolutely, a float setting will be ignored, so you will need to choose a width for #inner explicitly, and add padding in #outer to fake the text wrapping I suspect you want. For example, below, the padding of #outer is the width of #inner +3. Conveniently (as the whole point was to get #inner height to 100%) there's no need to wrap text beneath #inner, so this will look just like #inner is floated.

<style>
    #outer2{
        padding-left: 23px;
        position:absolute; 
        height:auto; 
        width:200px; 
        border: 1px solid red; 
    }
    #inner2{
        left:0;
        position:absolute; 
        height:100%; 
        width:20px; 
        border: 1px solid black; 
   }
</style>

<div id='outer2'>
    <div id='inner2'>
    </div>
    text
</div>

I deleted my previous answer, as it was based on too many wrong assumptions about your goal.

Try this:

in.nextLine();

This advances the Scanner to the next line.

I just had the exact same problem and it turned out to be caused by the fact that 2 projects in the same solution were referencing a different version of the 3rd party library.

Once I corrected all the references everything worked perfectly.

A functional approach to replacing an element of an array in javascript:

const replace = (array, index, ...items) => [...array.slice(0, index), ...items, ...array.slice(index + 1)];

I've faced the exactly same problem but I've fixed it with another approache.

Using Ubuntu 18.04, first disable systemd-resolved service.

sudo systemctl disable systemd-resolved.service

Stop the service

sudo systemctl stop systemd-resolved.service

Then, remove the link to /run/systemd/resolve/stub-resolv.conf in /etc/resolv.conf

sudo rm /etc/resolv.conf

Add a manually created resolv.conf in /etc/

sudo vim /etc/resolv.conf

Add your prefered DNS server there

nameserver 208.67.222.222

I've tested this with success.

You can do it just like with a property:

FieldInfo fi = typeof(Foo).GetField("_bar", BindingFlags.NonPublic | BindingFlags.Instance);
if (fi.GetCustomAttributes(typeof(SomeAttribute)) != null)
    ...

Try:

sudo -u postgres psql -c 'create database test;'

I am using header : null instead of header : { visible : true } i am using react-native cli. this is the example :

static navigationOptions = {
   header : null   
};

Attribute_Brands is a named range.

On any worksheet (tab) press F5 and type Attribute_Brands into the reference box and click on the OK button.

This will take you to the named range.

The data in it can be updated by typing new values into the cells.

The named range can be altered via the 'Insert - Name - Define' menu.

THIS ANSWER IS FOR ANIMATIONS ONLY


If you wanna implement the AND logic, you should use MultiTrigger, here is an example:

Suppose we want to do some actions if the property Text="" (empty string) AND IsKeyboardFocused="False", then your code should look like the following:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
        <MultiTrigger.EnterActions>
            <!-- Your actions here -->
        </MultiTrigger.EnterActions>
</MultiTrigger>

If you wanna implement the OR logic, there are couple of ways, and it depends on what you try to do:

The first option is to use multiple Triggers.
So, suppose you wanna do something if either Text="" OR IsKeyboardFocused="False",
then your code should look something like this:

<Trigger Property="IsEnabled" Value="false">
    <Setter Property="Opacity" TargetName="border" Value="0.56"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
    <Setter Property="BorderBrush" TargetName="border" 
            Value="{StaticResource TextBox.MouseOver.Border}"/>
</Trigger>

But the problem in this is what will I do if i wanna do something if either Text ISN'T null OR IsKeyboard="True"? This can be achieved by the second approach:
Recall De Morgan's rule, that says !(!x && !y) = x || y.
So we'll use it to solve the previous problem, by writing a multi trigger that it's triggered when Text="" and IsKeyboard="True", and we'll do our actions in EXIT ACTIONS, like this:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
    <MultiTrigger.ExitActions>
        <!-- Do something here -->
    </MultiTrigger.ExitActions>
</MultiTrigger>

All upper code is not correct to the end.

This is because when searching zz*foo* or zz* you will not get correct results.

And if you search "abcd*" in "abcd" in TotalCommander will he find a abcd file so all upper code is wrong.

Here is the correct code.

public string WildcardToRegex(string pattern)
{             
    string result= Regex.Escape(pattern).
        Replace(@"\*", ".+?").
        Replace(@"\?", "."); 

    if (result.EndsWith(".+?"))
    {
        result = result.Remove(result.Length - 3, 3);
        result += ".*";
    }

    return result;
}

Minor variation to user1850980's answer (for the question "How to initialize a list of empty dictionaries") using list constructor:

dictlistGOOD = list( {} for i in xrange(listsize) )

I found out to my chagrin, this does NOT work:

dictlistFAIL = [{}] * listsize  # FAIL!

as it creates a list of references to the same empty dictionary, so that if you update one dictionary in the list, all the other references get updated too.

Try these updates to see the difference:

dictlistGOOD[0]["key"] = "value"
dictlistFAIL[0]["key"] = "value"

(I was actually looking for user1850980's answer to the question asked, so his/her answer was helpful.)

In Java 7:

String folderPath = "C:/folderOfMyFile";
Path path = Paths.get(folderPath, "myFileName.csv"); //or any text file eg.: txt, bat, etc
Charset charset = Charset.forName("UTF-8");

try (BufferedReader reader = Files.newBufferedReader(path , charset)) {
  while ((line = reader.readLine()) != null ) {
    //separate all csv fields into string array
    String[] lineVariables = line.split(","); 
  }
} catch (IOException e) {
    System.err.println(e);
}

No, but int[] can be.

int[] hayhay = null; //: allowed (int[] is reference type)
int   hayno  = null; //: error   (int   is primitive type)
                     //: Message: incompatible types: 
                     //: <null> cannot be converted to int

Either != or ne will work, but you need to get the accessor syntax and nested quotes sorted out.

<c:if test="${content.contentType.name ne 'MCE'}">
    <%-- snip --%>
</c:if>

For all you non-xml config folks:

ObjectMapper objMapper = new ObjectMapper().setSerializationInclusion(JsonInclude.Include.NON_NULL);
HttpMessageConverter msgConverter = new MappingJackson2HttpMessageConverter(objMapper);
restTemplate.setMessageConverters(Collections.singletonList(msgConverter));

Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import to Tkinter rather than tkinter (the difference being the capitalization):

import tkinter as tk
#import Tkinter as tk  # for python 2
    
def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.

I had the same problem in the Terraform:light container. It is based on Alpine.

There you have to install mariadb-dev with:

apk add mariadb-dev

But that one is not enough because also all the other dependencies are missed:

apk add python2 py2-pip gcc python2-dev musl-dev

After trying several approaches I end up using an improved version of @warvariuc's answer:

import types

def func(_static=types.SimpleNamespace(counter=0)):
    _static.counter += 1
    print(_static.counter)

Got into django recently and been looking into a solution to that and found a method that might be useful.

So for example, if using allouth the default redirect is accounts/profile. Make a view that solely redirects to a location of choice using the username field like so:

def profile(request):
    name=request.user.username
    return redirect('-----choose where-----' + name + '/')

Then create a view that captures it in one of your apps, for example:

def profile(request, name):
    user = get_object_or_404(User, username=name)
    return render(request, 'myproject/user.html', {'profile': user})

Where the urlpatterns capture would look like this:

url(r'^(?P<name>.+)/$', views.profile, name='user')

Works well for me.

After adding the JDK repo, before Installing you might want to run an update first so the repo can be added run apt update

an then continue with your installation sudo apt install adoptopenjdk-8-hotspot

Here are some ways to change Navigation Bar color.

By the XML

1- values-v21/style.xml

<item name="android:navigationBarColor">@color/navigationbar_color</item>

Or if you want to do it only using the values/ folder then-

2- values/style.xml

<resources xmlns:tools="http://schemas.android.com/tools">

<item name="android:navigationBarColor" tools:targetApi="21">@color/navigationbar_color</item>

You can also change navigation bar color By Programming.

 if (Build.VERSION.SDK_INT >= 21)
    getWindow().setNavigationBarColor(getResources().getColor(R.color.navigationbar_color));

By Using Compat Library-

if (Build.VERSION.SDK_INT >= 21) {
    getWindow().setNavigationBarColor(ContextCompat.getColor(this, R.color.primary));
}

please find the link for more details- http://developer.android.com/reference/android/view/Window.html#setNavigationBarColor(int)

Google's Android Documentation Says that :

An asynchronous task is defined by 3 generic types, called Params, Progress and Result, and 4 steps, called onPreExecute, doInBackground, onProgressUpdate and onPostExecute.

AsyncTask's generic types :

The three types used by an asynchronous task are the following:

Params, the type of the parameters sent to the task upon execution.
Progress, the type of the progress units published during the background computation.
Result, the type of the result of the background computation.

Not all types are always used by an asynchronous task. To mark a type as unused, simply use the type Void:

 private class MyTask extends AsyncTask<Void, Void, Void> { ... }

You Can further refer : http://developer.android.com/reference/android/os/AsyncTask.html

Or You Can clear whats the role of AsyncTask by refering Sankar-Ganesh's Blog

Well The structure of a typical AsyncTask class goes like :

private class MyTask extends AsyncTask<X, Y, Z>

    protected void onPreExecute(){

    }

This method is executed before starting the new Thread. There is no input/output values, so just initialize variables or whatever you think you need to do.

    protected Z doInBackground(X...x){

    }

The most important method in the AsyncTask class. You have to place here all the stuff you want to do in the background, in a different thread from the main one. Here we have as an input value an array of objects from the type “X” (Do you see in the header? We have “...extends AsyncTask” These are the TYPES of the input parameters) and returns an object from the type “Z”.

   protected void onProgressUpdate(Y y){

   }

This method is called using the method publishProgress(y) and it is usually used when you want to show any progress or information in the main screen, like a progress bar showing the progress of the operation you are doing in the background.

  protected void onPostExecute(Z z){

  }

This method is called after the operation in the background is done. As an input parameter you will receive the output parameter of the doInBackground method.

What about the X, Y and Z types?

As you can deduce from the above structure:

 X – The type of the input variables value you want to set to the background process. This can be an array of objects.

 Y – The type of the objects you are going to enter in the onProgressUpdate method.

 Z – The type of the result from the operations you have done in the background process.

How do we call this task from an outside class? Just with the following two lines:

MyTask myTask = new MyTask();

myTask.execute(x);

Where x is the input parameter of the type X.

Once we have our task running, we can find out its status from “outside”. Using the “getStatus()” method.

 myTask.getStatus();

and we can receive the following status:

RUNNING - Indicates that the task is running.

PENDING - Indicates that the task has not been executed yet.

FINISHED - Indicates that onPostExecute(Z) has finished.

Hints about using AsyncTask

1. Do not call the methods onPreExecute, doInBackground and onPostExecute manually. This is automatically done by the system.

2. You cannot call an AsyncTask inside another AsyncTask or Thread. The call of the method execute must be done in the UI Thread.

3. The method onPostExecute is executed in the UI Thread (here you can call another AsyncTask!).

4. The input parameters of the task can be an Object array, this way you can put whatever objects and types you want.

There's a bit of a hack for this, since the HTML5 canvas is required to parse color values when certain properties like strokeStyle and fillStyle are set:

var ctx = document.createElement('canvas').getContext('2d');
ctx.strokeStyle = 'rgb(64, 128, 192)';
var hexColor = ctx.strokeStyle;

 if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {

        self.window.clipsToBounds =YES;
[application setStatusBarStyle:UIStatusBarStyleLightContent];
 self.window.frame =  CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height-20);
    }

1. Go to project properties (Alt+F7)
2. Under Debugging, look to the right
3. There's an Environment field.
4. Add your relative path there (relative to vcproj folder) i.e. ..\some-framework\lib by appending PATH=%PATH%;$(ProjectDir)\some-framework\lib or prepending to the path PATH=C:\some-framework\lib;%PATH%
5. Hit F5 (debug) again and it should work.

To compare any two files and merge it to one file Here are the following steps you can follow if you have visual studio(Any version) installed.

Step 1: Open Visual studio command prompt. If you do not find visual studio command prompt then choose visual studio tools

Start -> Visual studio command prompt

Step 2: Enter the command vsdiffmerge.exe

Ignore the switch /m if you need just comparison.

Syntax 1:
vsdiffmerge <file1> <file2> <file1> <outputfile> /t /m

Syntax 2:
vsdiffmerge <basefilename> <CompareFilename> <basefilename> <OutputFilename> /t /m

Example 1:
vsdiffmerge test1.js test2.js test1.js output.js /t /m
Example 2:
vsdiffmerge.exe "C:\Users\livingston\Downloads\wa\wa\Files\pre\Test.js" "C:\Users\livingston\Downloads\wa\wa\Files\Prod\Test.js" "C:\Users\livingston\Downloads\wa\wa\Files\pre\Test.js" "C:\Users\livingston\Downloads\wa\wa\Files\output\samp.js" /t /m

Step 3: Merge the files

Please note that if file name does not exists in the location, it will not open the comparer.

Also you can beautify the file before you do the comparison. In visual studio Ctrl + K + D.

There are lot of beautifier sites available online.

You may want to look into os dependent line separators, e.g.:

import os

with open('./output.txt', 'a') as f1:
    f1.write(content + os.linesep)

iirc :

cat filename.txt | awk '{ print $2 $4 }'

or, as mentioned in the comments :

awk '{ print $2 $4 }' filename.txt

Simple and with little changes. And also hide load more when entire list is loaded.

jsFiddle here.

$(document).ready(function () {
    // Load the first 3 list items from another HTML file
    //$('#myList').load('externalList.html li:lt(3)');
    $('#myList li:lt(3)').show();
    $('#showLess').hide();
    var items =  25;
    var shown =  3;
    $('#loadMore').click(function () {
        $('#showLess').show();
        shown = $('#myList li:visible').size()+5;
        if(shown< items) {$('#myList li:lt('+shown+')').show();}
        else {$('#myList li:lt('+items+')').show();
             $('#loadMore').hide();
             }
    });
    $('#showLess').click(function () {
        $('#myList li').not(':lt(3)').hide();
    });
});

#include <stdio.h>

int main() {

  printf("gcc version: %d.%d.%d\n",__GNUC__,__GNUC_MINOR__,__GNUC_PATCHLEVEL__);
  return 0;
}

You can find an example below. Basically you attach a function to window's scroll event and trace scrollTop property and if it's higher than desired threshold you apply position: fixed and some other css properties.

jQuery(function($) {_x000D_
  $(window).scroll(function fix_element() {_x000D_
    $('#target').css(_x000D_
      $(window).scrollTop() > 100_x000D_
        ? { 'position': 'fixed', 'top': '10px' }_x000D_
        : { 'position': 'relative', 'top': 'auto' }_x000D_
    );_x000D_
    return fix_element;_x000D_
  }());_x000D_
});

body {_x000D_
  height: 2000px;_x000D_
  padding-top: 100px;_x000D_
}_x000D_
code {_x000D_
  padding: 5px;_x000D_
  background: #efefef;_x000D_
}_x000D_
#target {_x000D_
  color: #c00;_x000D_
  font: 15px arial;_x000D_
  padding: 10px;_x000D_
  margin: 10px;_x000D_
  border: 1px solid #c00;_x000D_
  width: 200px;_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="target">This <code>div</code> is going to be fixed</div>

Original question was to parse a list of topics, however starting with the original example to have a function return a single value may also useful. To that end, here is an example of (one way) to do that:

<script type='text/javascript'>
    function getSingleValueUsingJQuery() {
      var value = "";
      var url = "rest/endpointName/" + document.getElementById('someJSPFieldName').value;
      jQuery.ajax({
        type: 'GET',
        url: url,
        async: false,
        contentType: "application/json",
        dataType: 'json',
        success: function(json) {
          console.log(json.value);   // needs to match the payload (i.e. json must have {value: "foo"}
          value = json.value;
        },
        error: function(e) {
          console.log("jQuery error message = "+e.message);
        }
      });
      return value;
    }
    </script>
    

In using toolbar you should extends AppCompatActivity and

import android.support.v7.widget.Toolbar 

You need to push i

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

for (var i = yearStart; i < yearEnd+1; i++) {
    arr.push(i);
}

Then, your resulting array will be:

arr = [2000, 2001, 2003, ... 2039, 2040]

Hope this helps

Creating dataframe from dictionary object.

import pandas as pd
data = [{'name': 'vikash', 'age': 27}, {'name': 'Satyam', 'age': 14}]
df = pd.DataFrame.from_dict(data, orient='columns')

df
Out[4]:
   age  name
0   27  vikash
1   14  Satyam

If you have nested columns then you first need to normalize the data:

data = [
  {
    'name': {
      'first': 'vikash',
      'last': 'singh'
    },
    'age': 27
  },
  {
    'name': {
      'first': 'satyam',
      'last': 'singh'
    },
    'age': 14
  }
]

df = pd.DataFrame.from_dict(pd.json_normalize(data), orient='columns')

df    
Out[8]:
age name.first  name.last
0   27  vikash  singh
1   14  satyam  singh

<!DOCTYPE html>

The meta tag must be the first tag after the head tag or it will not work.

The clearest way to express polymorphism is via an abstract base class (or interface)

public abstract class Human{
   ...
   public abstract void goPee();
}

This class is abstract because the goPee() method is not definable for Humans. It is only definable for the subclasses Male and Female. Also, Human is an abstract concept — You cannot create a human that is neither Male nor Female. It’s got to be one or the other.

So we defer the implementation by using the abstract class.

public class Male extends Human{
...
    @Override
    public void goPee(){
        System.out.println("Stand Up");
    }
}

and

public class Female extends Human{
...
    @Override
    public void goPee(){
        System.out.println("Sit Down");
    }
}

Now we can tell an entire room full of Humans to go pee.

public static void main(String[] args){
    ArrayList<Human> group = new ArrayList<Human>();
    group.add(new Male());
    group.add(new Female());
    // ... add more...

    // tell the class to take a pee break
    for (Human person : group) person.goPee();
}

Running this would yield:

Stand Up
Sit Down
...

Try the formula

=TEXT(TODAY(),"MMYYYY")

You have a certificate which is self-signed, so it's non-trusted by default, that's why OpenSSL complains. This warning is actually a good thing, because this scenario might also rise due to a man-in-the-middle attack.

To solve this, you'll need to install it as a trusted server. If it's signed by a non-trusted CA, you'll have to install that CA's certificate as well.

Have a look at this link about installing self-signed certificates.

Added below to pom.xml file and it worked eventually: 

<dependency>

What I did in my case was to update

"lib": [
      "es2020",
      "dom"
    ]

with

"lib": [
  "es2016",
  "dom"
]

in my tsconfig.json file

This will give you one row of each duplicate row. It will also give you the bit-type columns, and it works at least in MS Sql Server.

(select cname, address 
from (
  select cname,address, rn=row_number() over (partition by cname order by cname) 
  from customeraddresses  
) x 
where rn = 1) order by cname

If you want to find all the duplicates instead, just change the rn= 1 to rn > 1. Hope this helps

Swift 5 Protocol Extension

Here is an approach using protocol extension so that you can easily inline an optional nil check:

import Foundation

public extension Optional {

    var isNil: Bool {

        guard case Optional.none = self else {
            return false
        }

        return true

    }

    var isSome: Bool {

        return !self.isNil

    }

}

Usage

var myValue: String?

if myValue.isNil {
    // do something
}

if myValue.isSome {
    // do something
}

If you want to benchmark, you can use os.clock as shown by the doc:

local x = os.clock()
local s = 0
for i=1,100000 do s = s + i end
print(string.format("elapsed time: %.2f\n", os.clock() - x))

If it is inline equation, then use \allowbreak. Use it like:

$x_1,x_2,x_3,\allowbreak x_4,x_5$.

Latex will break equation in this place only if necessary.

It's good to know that

but also know that math.log takes an optional second argument which allows you to specify the base:

In [22]: import math

In [23]: math.log?
Type:       builtin_function_or_method
Base Class: <type 'builtin_function_or_method'>
String Form:    <built-in function log>
Namespace:  Interactive
Docstring:
    log(x[, base]) -> the logarithm of x to the given base.
    If the base not specified, returns the natural logarithm (base e) of x.


In [25]: math.log(8,2)
Out[25]: 3.0

Organize your files in hierarchical directories and then just use relative paths.

Demo:

HTML (index.html)

<a href='inner/file.html'>link</a>

Directory structure:

base/
base/index.html
base/inner/file.html
....

This is question was posted like ages back, but today when i was looking for the same answer "How to detect zoom in and out event", i couldn't find one answer that would fit all the browsers.

As on now : For Firefox/Chrome/IE8 and IE9 , the zoom in and out fires a window.resize event. This can be captured using:

$(window).resize(function() {
//YOUR CODE.
});

Here's another for C# that I used when doing a sample server control. It can be found in the book ASP.NET 3.5 Step by Step (MS Press). It's two methods, one to strip non-alphanumerics, and another to check for a palindrome.

protected string StripNonAlphanumerics(string str)
{
    string strStripped = (String)str.Clone();
    if (str != null)
    {
        char[] rgc = strStripped.ToCharArray();
        int i = 0;
        foreach (char c in rgc)
        {
            if (char.IsLetterOrDigit(c))
            {
                i++;
            }
            else
            {
                strStripped = strStripped.Remove(i, 1);
            }
        }
    }
    return strStripped;
}
protected bool CheckForPalindrome()
{
    if (this.Text != null)
    {
        String strControlText = this.Text;
        String strTextToUpper = null;
        strTextToUpper = Text.ToUpper();
        strControlText =
                    this.StripNonAlphanumerics(strTextToUpper);
        char[] rgcReverse = strControlText.ToCharArray();
        Array.Reverse(rgcReverse);
        String strReverse = new string(rgcReverse);
        if (strControlText == strReverse)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
    else
    {
        return false;
    }
}

if you are inside the actual function, you can use arguments.callee as a reference to the function. as in:

button.addEventListener('click', function() {
      ///this will execute only once
      alert('only once!');
      this.removeEventListener('click', arguments.callee);
});

EDIT: This will not work if you are working in strict mode ("use strict";)

Keyword parameters allow you to pass variables from one function to another. In this way you can use the key of a dictionary as a variable name (which can be populated in your while loop). The dictionary name just needs to be preceded by ** when it is called.

# create a dictionary
>>> kwargs = {}
# add a key of name and assign it a value, later we'll use this key as a variable
>>> kwargs['name'] = 'python'

# an example function to use the variable
>>> def print_name(name):
...   print name

# call the example function
>>> print_name(**kwargs)
python

Without **, kwargs is just a dictionary:

>>> print_name(kwargs)
{'name': 'python'}

Update

My recomendation would be to shred the XML into relations and do searches and joins on the resulted relation, in a set oriented fashion, rather than the procedural fashion of searching specific nodes in the XML. Here is a simple XML query that shreds out the nodes and attributes of interest:

select x.value(N'../../../../@stepId', N'int') as StepID
  , x.value(N'../../@id', N'int') as ComponentID
  , x.value(N'@nom',N'nvarchar(100)') as Nom
  , x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box/components/component/variables/variable') t(x)

However, if you must use an XPath that retrieves exactly the value of interest:

select x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
       variables/variable[@nom="Enabled"]') t(x)

If the stepID and component ID are columns, not variables, the you should use sql:column() instead of sql:variable in the XPath filters. See Binding Relational Data Inside XML Data.

And finaly if all you need is to check for existance you can use the exist() XML method:

select @x.exist(
  N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
      variables/variable[@nom="Enabled" and @valeur="Yes"]') 

From jQuery.ajax()

async Boolean
Default: true
By default, all requests are sent asynchronously (i.e. this is set to true by default). If you need synchronous requests, set this option to false.

So in your request, you must do async: false instead of async: "false".

Update:

The return value of ajaxSubmit is not the return value of the success: function(){...}. ajaxSubmit returns no value at all, which is equivalent to undefined, which in turn evaluates to true.

And that is the reason, why the form is always submitted and is independent of sending the request synchronous or not.

If you want to submit the form only, when the response is "Successful", you must return false from ajaxSubmit and then submit the form in the success function, as @halilb already suggested.

Something along these lines should work

function ajaxSubmit() {
    var password = $.trim($('#employee_password').val());
    $.ajax({
        type: "POST",
        url: "checkpass.php",
        data: "password="+password,
        success: function(response) {
            if(response == "Successful")
            {
                $('form').removeAttr('onsubmit'); // prevent endless loop
                $('form').submit();
            }
        }
    });

    return false;
}

var offset = curdate.getTimezoneOffset()

This method returns time zone offset in minutes which is the difference between GMT and local time in minutes.

Use this:

The real problem is that the variable line always has a value. The test for "no matches found" is whether there is a match so the code "if line == None:" should be replaced with "else:"

How about

a["abc"] = [1, 2]

This will result in:

{'abc': [1, 2]}

Is that what you were looking for?

It depends on how and when you want to redirect the user to another page.

If you want to instantly redirect a user to another page without him seeing anything of a site in between, you should use the PHP header redirect method.

If you have a Javascript and some action of the user has to result in him entering another page, that is when you should use window.location.

The meta tag refresh is often used on download sites whenever you see these "Your download should start automatically" messages. You can let the user load a page, wait for a certain amount of time, then redirect him (e.g. to a to-be-downloaded file) without Javascript.

Keyboard accelerators are configurable. You can find out which keyboard accelerators are bound to a command in Tools -> Options on the Environment -> Keyboard page.

These commands are named Edit.CommentSelection and Edit.UncommentSelection.

(With my settings, these are bound to Ctrl+K, Ctrl+C and Ctrl+K, Ctrl+U. I would guess that these are the defaults, at least in the C++ defaults, but I don't know for sure. The best way to find out is to check your settings.)

One more solution able to control the how many decimal digits to print out based on needs (if you don't want to print redundant zero(s))

For example, if you have a vector as elements and would like to get sum of it

elements <- c(-1e-05, -2e-04, -3e-03, -4e-02, -5e-01, -6e+00, -7e+01, -8e+02)
sum(elements)
## -876.5432

Apparently, the last digital as 1 been truncated, the ideal result should be -876.54321, but if set as fixed printing decimal option, e.g sprintf("%.10f", sum(elements)), redundant zero(s) generate as -876.5432100000

Following the tutorial here: printing decimal numbers, if able to identify how many decimal digits in the certain numeric number, like here in -876.54321, there are 5 decimal digits need to print, then we can set up a parameter for format function as below:

decimal_length <- 5
formatC(sum(elements), format = "f", digits = decimal_length)
## -876.54321

We can change the decimal_length based on each time query, so it can satisfy different decimal printing requirement.

You'll need to compile it using:

g++ inputfile.cpp -o outputbinary

The file you are referring has a missing #include <cstdlib> directive, if you also include that in your file, everything shall compile fine.

I used this one (kind of mix of different answers, but anyway):

const isJSON = str => {_x000D_
  if (typeof str === 'string'){_x000D_
    try {_x000D_
      JSON.parse(str)_x000D_
      return true_x000D_
    } catch(e){_x000D_
    }_x000D_
  }_x000D_
  return false_x000D_
}_x000D_
_x000D_
_x000D_
_x000D_
[null, undefined, false, true, [], {}, _x000D_
 '', 'asdf', '{}', '[]', "{\"abc\": 2}","{\"abc\": \"2\"}"]_x000D_
  .map(el => {_x000D_
      console.log(`[>${el}<] - ${isJSON(el)}`)_x000D_
})_x000D_
_x000D_
console.log('-----------------')

Just for reference, here is a benchmark of different technique rendering performances,

OK, finally we have an answer...

You are correctly specifying headers: {"Content-Type": "application/json"}, to set your content type. Under the hood either the package http or the lower level dart:io HttpClient is changing this to application/json; charset=utf-8. However, your server web application obviously isn't expecting the suffix.

To prove this I tried it in Java, with the two versions

conn.setRequestProperty("content-type", "application/json; charset=utf-8"); // fails
conn.setRequestProperty("content-type", "application/json"); // works

Are you able to contact the web application owner to explain their bug? I can't see where Dart is adding the suffix, but I'll look later.

EDIT Later investigation shows that it's the http package that, while doing a lot of the grunt work for you, is adding the suffix that your server dislikes. If you can't get them to fix the server then you can by-pass http and use the dart:io HttpClient directly. You end up with a bit of boilerplate which is normally handled for you by http.

Working example below:

import 'dart:convert';
import 'dart:io';
import 'dart:async';

main() async {
  String url =
      'https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';
  Map map = {
    'data': {'apikey': '12345678901234567890'},
  };

  print(await apiRequest(url, map));
}

Future<String> apiRequest(String url, Map jsonMap) async {
  HttpClient httpClient = new HttpClient();
  HttpClientRequest request = await httpClient.postUrl(Uri.parse(url));
  request.headers.set('content-type', 'application/json');
  request.add(utf8.encode(json.encode(jsonMap)));
  HttpClientResponse response = await request.close();
  // todo - you should check the response.statusCode
  String reply = await response.transform(utf8.decoder).join();
  httpClient.close();
  return reply;
}

Depending on your use case, it may be more efficient to re-use the HttpClient, rather than keep creating a new one for each request. Todo - add some error handling ;-)

The Address property of a cell can get this for you:

MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False)

returns A1.

The other way around can be done with the Row and Column property of Range:

MsgBox Range("A1").Row & ", " & Range("A1").Column

returns 1,1.

Just drop them:

nms.dropna(thresh=2)

this will drop all rows where there are at least two non-NaN.

Then you could then drop where name is NaN:

In [87]:

nms
Out[87]:
  movie    name  rating
0   thg    John       3
1   thg     NaN       4
3   mol  Graham     NaN
4   lob     NaN     NaN
5   lob     NaN     NaN

[5 rows x 3 columns]
In [89]:

nms = nms.dropna(thresh=2)
In [90]:

nms[nms.name.notnull()]
Out[90]:
  movie    name  rating
0   thg    John       3
3   mol  Graham     NaN

[2 rows x 3 columns]

EDIT

Actually looking at what you originally want you can do just this without the dropna call:

nms[nms.name.notnull()]

UPDATE

Looking at this question 3 years later, there is a mistake, firstly thresh arg looks for at least n non-NaN values so in fact the output should be:

In [4]:
nms.dropna(thresh=2)

Out[4]:
  movie    name  rating
0   thg    John     3.0
1   thg     NaN     4.0
3   mol  Graham     NaN

It's possible that I was either mistaken 3 years ago or that the version of pandas I was running had a bug, both scenarios are entirely possible.

If BranchA has not been pushed to a remote then you can reorder the commits using rebase and then simply merge. It's preferable to use merge over rebase when possible because it doesn't create duplicate commits.

git checkout BranchA
git rebase -i HEAD~113
... reorder the commits so the 10 you want are first ...
git checkout BranchB
git merge [the 10th commit]

I am facing the same issue on Xcode 7.3 and my device version is iOS 10.

This error is shown when your Xcode is old and the related device you are using is updated to latest version. First of all, install the latest Xcode version.

We can solve this issue by following the below steps:-

• Open Finder select Applications
• Right click on Xcode 8, select "Show Package Contents", "Contents", "Developer", "Platforms", "iPhoneOS.Platform", "Device Support"
• Copy the 10.0 folder (or above for later version).
• Back in Finder select Applications again
• Right click on Xcode 7.3, select "Show Package Contents", "Contents", "Developer", "Platforms", "iPhoneOS.Platform", "Device Support"
• Paste the 10.0 folder

If everything worked properly, your Xcode has a new developer disk image. Close the finder now, and quit your Xcode. Open your Xcode and the error will be gone. Now you can connect your latest device to old Xcode versions.

Thanks

Using class members to give default values works very well just so long as you are careful only to do it with immutable values. If you try to do it with a list or a dict that would be pretty deadly. It also works where the instance attribute is a reference to a class just so long as the default value is None.

I've seen this technique used very successfully in repoze which is a framework that runs on top of Zope. The advantage here is not just that when your class is persisted to the database only the non-default attributes need to be saved, but also when you need to add a new field into the schema all the existing objects see the new field with its default value without any need to actually change the stored data.

I find it also works well in more general coding, but it's a style thing. Use whatever you are happiest with.

From Windows 10 version 1607, the limitation has been removed by setting a registry key

I think what you're looking for is !!val==false which can be turned to !val (even shorter):

You see:

function checkValue(value) {
    console.log(!!value);
}

checkValue(); // false
checkValue(null); // false
checkValue(undefined); // false
checkValue(false); // false
checkValue(""); // false

checkValue(true); // true
checkValue({}); // true
checkValue("any string"); // true

That works by flipping the value by using the ! operator.

If you flip null once for example like so :

console.log(!null) // that would output --> true

If you flip it twice like so :

console.log(!!null) // that would output --> false

Same with undefined or false.

Your code:

if(val==null || val===false){
  ;
}

would then become:

if(!val) {
  ;
}

That would work for all cases even when there's a string but it's length is zero. Now if you want it to also work for the number 0 (which would become false if it was double flipped) then your if would become:

if(!val && val !== 0) {
  // code runs only when val == null, undefined, false, or empty string ""
}

$("#id").autocomplete(
{
    search: function () {},
    source: function (request, response)
    {
        $.ajax(
        {
            url: ,
            dataType: "json",
            data:
            {
                term: request.term,
            },
            success: function (data)
            {
                response(data);
            }
        });
    },
    minLength: 2,
    select: function (event, ui)
    {
        var test = ui.item ? ui.item.id : 0;
        if (test > 0)
        {
           alert(test);
        }
    }
});

Use the following script after appending your select.

$('#state').select2();

Don't use destroy.

If you've exported the environment variable:

export demoPath=/usr/local/demo

you can simply refer to it by name in the makefile (make imports all the environment variables you have set):

DEMOPATH = ${demoPath}    # Or $(demoPath) if you prefer.

If you've not exported the environment variable, it is not accessible until you do export it, or unless you pass it explicitly on the command line:

make DEMOPATH="${demoPath}" …

If you are using a C shell derivative, substitute setenv demoPath /usr/local/demo for the export command.
