Another way of configuring backup options is via the Customize interface. Enter:

M-x customize-group

And then at the Customize group: prompt enter backup.

If you scroll to the bottom of the buffer you'll see Backup Directory Alist. Click Show Value and set the first entry of the list as follows:

Regexp matching filename: .*
Backup directory name: /path/to/your/backup/dir

Alternatively, you can turn backups off my setting Make Backup Files to off.

If you don't want Emacs to automatically edit your .emacs file you'll want to set up a customisations file.

MSBuild in an independent build tool that is frequently bundled with other tools. It may have been installed on your computer with .NET (older versions), Visual Studio (newer versions), or even Team Foundation Build.

MSBuild needs configuration files, compilers, etc (a ToolSet) that matches the version of Visual Studio or TFS that will use it, as well as the version of .NET against which source code will be compiled.

Depending on how MSBuild was installed, the configuration files may be in one or more of these paths.

• C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\
• C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\
• C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\

As described in other answers, a registry item and/or environmental variable point must to the ToolSet path.

• The VCTargetsPath key under HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0
• The VCTargetsPath environmental variable.

Occasionally, an operation like installing a tool will leave the registry and/or environmental variable set incorrectly. The other answers are all variations on fixing them.

The only thing I have to add is the environmental variable didn't work for me when I left off the trailing \

Use the Activity Monitor. It's the last toolbar in the top bar. It will show you a list of "Recent Expensive Queries". You can double-click them to see the execution plan, etc.

For me i put this codes in public\index.php file. and it worked just fine for all CRUD operations.

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS, post, get');
header("Access-Control-Max-Age", "3600");
header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token');

I just discovered the Hmisc package:

Contains many functions useful for data analysis, high-level graphics, utility operations, functions for computing sample size and power, importing and annotating datasets, imputing missing values, advanced table making, variable clustering, character string manipulation, conversion of R objects to LaTeX and html code, and recoding variables.

REST-ful usage

POST is used to create a new resource and then returns the resource URI

EX 
      REQUEST : POST ..../books
        {
        "book":"booName",
        "author":"authorName"
        }

This call may create a new book and returns that book URI

Response ...THE-NEW-RESOURCE-URI/books/5

PUT is used to replace a resource, if that resource is exist then simply update it, but if that resource doesn't exist then create it,

REQUEST : PUT ..../books/5
{
"book":"booName",
"author":"authorName"
}

With PUT we know the resource identifier, but POST will return the new resource identifier

Non REST-ful usage

POST is used to initiate an action on the server side, this action may or may not create a resource, but this action will have side affects always it will change something on the server

PUT is used to place or replace literal content at a specific URL

Another difference in both REST-ful and non REST-ful styles

POST is Non-Idempotent Operation: It will cause some changes if executed multiple times with the same request.

PUT is Idempotent Operation: It will have no side-effects if executed multiple times with the same request.

Do you have several swf-files? If your class is imported in one of the swf's, other swf's will also use the same version of the class. One old import with * in one swf will do it. Recompile everything and see if it works.

You can use as keyword to refer a collection under a ng-repeat element:

<table>
    <tr ng-repeat="task in tasks | filter:category | filter:query as res">
        <td>{{task.id}}</td>
        <td>{{task.description}}</td>
    </tr>
    <tr ng-if="res.length === 0">
        <td colspan="2">no results</td>
    </tr>
</table>

And many lines may look like this. The html here is sample only.

var div = document.createElement("div");

div.innerHTML =
    '<div class="slideshow-container">\n' +
    '<div class="mySlides fade">\n' +
    '<div class="numbertext">1 / 3</div>\n' +
    '<img src="image1.jpg" style="width:100%">\n' +
    '<div class="text">Caption Text</div>\n' +
    '</div>\n' +

    '<div class="mySlides fade">\n' +
    '<div class="numbertext">2 / 3</div>\n' +
    '<img src="image2.jpg" style="width:100%">\n' +

    '</div>\n' +
    '<br>\n' +

    '<div style="text-align:center">\n' +
    '<span class="dot" onclick="currentSlide(1)"></span> \n' +
    '<span class="dot" onclick="currentSlide(2)"></span> \n' +
    '<span class="dot" onclick="currentSlide(3)"></span> \n' +
    '</div>\n';

document.body.appendChild(div);

Changing to format: 'dd/mm/yyyy' didn't work for me, and changing that to dateFormat: 'dd/mm/yyyy' added year multiple times, The finest one for me was,

dateFormat: 'dd/mm/yy'

new Date(YOUR_DATE_STRING).toLocaleDateString(navigator.language)

~ combination of answers of above

Check the design and API specification (it's still a draft) or check the source from (page no longer available) for a simple example: It's mainly a call to window.webkitNotifications.createNotification.

If you want a more robust example (you're trying to create your own Google Chrome's extension, and would like to know how to deal with permissions, local storage and such), check out Gmail Notifier Extension: download the crx file instead of installing it, unzip it and read its source code.

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:

http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• http://www.mssqltips.com/sqlservertip/2632/checking-for-potential-constraint-violations-before-entering-sql-server-try-and-catch-logic/
• http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling

Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.

I know this is an older question, but I felt the answer from t3chb0t led me to the best path and felt like sharing. You don't even need to go so far as implementing all the formatter's methods. I did the following for the content-type "application/vnd.api+json" being returned by an API I was using:

public class VndApiJsonMediaTypeFormatter : JsonMediaTypeFormatter
{
    public VndApiJsonMediaTypeFormatter()
    {
        SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/vnd.api+json"));
    }
}

Which can be used simply like the following:

HttpClient httpClient = new HttpClient("http://api.someaddress.com/");
HttpResponseMessage response = await httpClient.GetAsync("person");

List<System.Net.Http.Formatting.MediaTypeFormatter> formatters = new List<System.Net.Http.Formatting.MediaTypeFormatter>();
formatters.Add(new System.Net.Http.Formatting.JsonMediaTypeFormatter());
formatters.Add(new VndApiJsonMediaTypeFormatter());

var responseObject = await response.Content.ReadAsAsync<Person>(formatters);

Super simple and works exactly as I expected.

Seems like you could use date() and the lowercase "L" format character in the following way:

$weekday_name = date("l", $timestamp);

Works well for me, here is the doc: http://php.net/manual/en/function.date.php

Here's a quick, admittedly butchered response, but in a sentence:

1NF : Your table is organized as an unordered set of data, and there are no repeating columns.

2NF: You don't repeat data in one column of your table because of another column.

3NF: Every column in your table relates only to your table's key -- you wouldn't have a column in a table that describes another column in your table which isn't the key.

For more detail, see wikipedia...

A variation on the previous answers. I found that opacity needs to be set, of course this will work in IE6 and on. There was a problem with the line-height solution in IE8 where the button would not respond. And with this you get a hand cursor as well!

<div id="myButton">
  <input id="myInputButton" type="submit" name="" value="">
</div>

#myButton {
 background: url("form_send_button.gif") no-repeat;
 width: 62px;
 height: 24px;
 }

#myInputButton { 
 background: url("form_send_button.gif") no-repeat;
 opacity: 0;
 -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
 filter: alpha(opacity=0);
 width: 67px;
 height: 26px;
 cursor: pointer;
 cursor: hand;
}

SELECT CONVERT(Datetime, '2011-09-28 18:01:00', 120) -- to convert it to Datetime

SELECT CONVERT( VARCHAR(30), @date ,105) -- italian format [28-09-2011 18:01:00]
+ ' ' + SELECT CONVERT( VARCHAR(30), @date ,108 ) -- full date [with time/minutes/sec]

to see changes that are not merged, I did this:

git checkout experiment
git merge --no-commit master

git diff --cached

Note: This shows changes in master that are not in experiment.

Don't forget to:

git merge --abort

When you're done lookin.

Just u can use with using System.Linq;

List<string> stringList = line.Split(',')     // this is array
 .ToList();     // this is a list which you can loop in all split string

In my case error came due to following reason

• Initially it was working fine,then i renamed one variable,made the changes in code and it gave me this error.

• Then i applied jackson ignorant property also but it did not work.

• Finally after re defining my getters and setters methods according to name of my variable this error was resolved

So make sure to redifine getters and setters also.

The simplest answer!

P.S. the one who wrote the document of argparse is foolish

python code:

import argparse
parser = argparse.ArgumentParser(description='')
parser.add_argument('--o_dct_fname',type=str)
parser.add_argument('--tp',type=str)
parser.add_argument('--new_res_set',type=int)
args = parser.parse_args()
o_dct_fname = args.o_dct_fname
tp = args.tp
new_res_set = args.new_res_set

running code

python produce_result.py --o_dct_fname o_dct --tp father_child --new_res_set 1

Java 8 Had changed the world you can have static methods in interface but it forces you to provide implementation for that.

public interface StaticMethodInterface {
public static int testStaticMethod() {
    return 0;
}

/**
 * Illegal combination of modifiers for the interface method
 * testStaticMethod; only one of abstract, default, or static permitted
 * 
 * @param i
 * @return
 */
// public static abstract int testStaticMethod(float i);

default int testNonStaticMethod() {
    return 1;
}

/**
 * Without implementation.
 * 
 * @param i
 * @return
 */
int testNonStaticMethod(float i);

}

You can try to implement something like that, look at:

Map<String, Integer> map = new LinkedHashMap<String, Integer>();
map.put("juan", 2);
map.put("pedro", 3);
map.put("pablo", 5);
map.put("iphoncio",9)

List<String> indexes = new ArrayList<String>(map.keySet()); // <== Parse

System.out.println(indexes.indexOf("juan"));     // ==> 0
System.out.println(indexes.indexOf("iphoncio"));      // ==> 3

I hope this works for you.

I noticed something perhaps relevant.

I had two scripts running, both doing rather slow queries. One of them locked a table and the other had to wait. The one that was waiting had default_socket_timeout = 300. Eventually it quit with "MySQL server has gone away". However, the mysql process list continued to show both query, the slow one still running and the other locked and waiting.

So I don't think mysqld is the culprit. Something has changed in the php mysql client. Quite possibly the default_socket_timeout which I will now set to -1 to see if that changes anything.

The accepted solution has an issue with the need to maintain the same statement twice, it isnt very efficient (although it works). In theory Gordon Linoff's solution would be the go, except it does not work in MSSQL because create view must be the first line in a batch.

The drop/create does not answer the question as posed. The following does the job as per the original question.

if not exists (select * from sysobjects where name='TABLE_A' and xtype='V')
exec ('create view SELECT 
VCV.xxxx,
    VCV.yyyy AS yyyy,
    VCV.zzzz AS zzzz
FROM TABLE_A')

Figured out my own problem. The solution ended up being based in interpolators.

Animation fadeIn = new AlphaAnimation(0, 1);
fadeIn.setInterpolator(new DecelerateInterpolator()); //add this
fadeIn.setDuration(1000);

Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setInterpolator(new AccelerateInterpolator()); //and this
fadeOut.setStartOffset(1000);
fadeOut.setDuration(1000);

AnimationSet animation = new AnimationSet(false); //change to false
animation.addAnimation(fadeIn);
animation.addAnimation(fadeOut);
this.setAnimation(animation);

If you are using Kotlin

val fadeIn = AlphaAnimation(0f, 1f)
fadeIn.interpolator = DecelerateInterpolator() //add this
fadeIn.duration = 1000

val fadeOut = AlphaAnimation(1f, 0f)
fadeOut.interpolator = AccelerateInterpolator() //and this
fadeOut.startOffset = 1000
fadeOut.duration = 1000

val animation = AnimationSet(false) //change to false
animation.addAnimation(fadeIn)
animation.addAnimation(fadeOut)
this.setAnimation(animation)

You need to set the "default value" for the date field to getdate(). Any records inserted into the table will automatically have the insertion date as their value for this field.

The location of the "default value" property is dependent on the version of SQL Server Express you are running, but it should be visible if you select the date field of your table when editing the table.

One line checking on true/false if cert of domain will be expired in some time later(ex. 15 days):

openssl x509 -checkend $(( 24*3600*15 )) -noout -in <(openssl s_client -showcerts -connect my.domain.com:443 </dev/null 2>/dev/null | openssl x509 -outform PEM)
if [ $? -eq 0 ]; then
  echo 'good'
else
  echo 'bad'
fi

You have conditions that are mutually exclusive - if meta_key is 'first_name', it can't also be 'yearofpassing'. Most likely you need your AND's to be OR's:

$result = mysql_query("SELECT user_id FROM wp_usermeta 
WHERE (meta_key = 'first_name' AND meta_value = '$us_name') 
OR (meta_key = 'yearofpassing' AND meta_value = '$us_yearselect') 
OR (meta_key = 'u_city' AND meta_value = '$us_reg') 
OR (meta_key = 'us_course' AND meta_value = '$us_course')")

It's simple, use $.getJSON() function and in your URL just include

callback=?

as a parameter. That will convert the call to JSONP which is necessary to make cross-domain calls. More info: http://api.jquery.com/jQuery.getJSON/

You can change an HTML5 input's placeholder color with CSS. If by chance, your CSS conflict, this code note working , you can use (!important) like below.

::-webkit-input-placeholder { /* WebKit, Blink, Edge */
    color:#909 !important;
}
:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
   color:#909 !important;
   opacity:1 !important;
}
::-moz-placeholder { /* Mozilla Firefox 19+ */
   color:#909 !important;
   opacity:1 !important;
}
:-ms-input-placeholder { /* Internet Explorer 10-11 */
   color:#909 !important;
}
::-ms-input-placeholder { /* Microsoft Edge */
   color:#909 !important;
}

<input placeholder="Stack Snippets are awesome!">

Hope this will help.

ls /usr/share/fonts/truetype/msttcorefonts/

This folder just had the README, with the correct instructions on how to install.

cat /usr/share/fonts/truetype/msttcorefonts/README

You need an internet connection for this:

sudo apt-get install --reinstall ttf-mscorefonts-installer

I re-installed ttf-mscorefonts-installer (as shown above, making sure to accept the EULA!) and the problem was solved.

I think the one thing that I know GIT wins on is it's ability to "preserve line endings" on all files, whereas perforce seems to insist on translating them into either Unix, Dos/Windows or MacOS9 format ("\n", "\r\n" or "\r).

This is a real pain if you're writing Unix scripts in a Windows environment, or a mixed OS environment. It's not even possible to set the rule on a per-file-extension basis. For instance, it would convert .sh, .bash, .unix files to Unix format, and convert .ccp, .bat or .com files to Dos/Windows format.

In GIT (I'm not sure if that's default, an option or the only option) you can set it up to "preserve line endings". That means, you can manually change the line endings of a file, and then GIT will leave that format the way it is. This seems to me like the ideal way to do things, and I don't understand why this isn't an option with Perforce.

The only way you can achieve this behavior, is to mark the files as binary. As I see that, that would be a nasty hack to workaround a missing feature. Apart from being tedious to have to do on all scripts, etc, it would also probably break most diffs, etc.

The "solution" that we've settled for at the moment, is to run a sed command to remove all carriage returns from the scripts every time they're deployed to their Unix environment. This isn't ideal either, especially since some of them are deployed inside WAR files, and the sed line has to be run again when they're unpacked.

This is just something I think gives GIT a great advantage, and which I don't think has been mentioned above.

EDIT: After having been using Perforce for a bit longer, I'd like to add another couple of comments:

A) Something I really miss in Perforce is a clear and instance diff, including changed, removed and added files. This is available in GIT with the git diff command, but in Perforce, files have to be checked out before their changes are recorded, and while you might have your main editors (like Eclipse) set up to automatically check files out when you edit them, you might sometimes edit files in other ways (notepad, unix commands, etc). And new files don't seem to be added automatically at all, even using Eclipse and p4eclipse, which can be rather annoying. So to find all changes, you have to run a "Diff against..." on the entire workspace, which first of all takes a while to run, and secondly includes all kind of irrelevant things unless you set up very complicated exclusion lists, which leads me to the next point.

B) In GIT I find the .gitignore very simple and easy to manage, read and understand. However, the workspace ignore/exclude lists configurable in Perforce seem unwieldy and unnecessarily complex. I haven't been able to get any exclusions with wildcards working. I would like to do something like

-//Server/mainline/.../target/...   //Svend_Hansen_Server/.../target/...

To exclude all target folders within all projects inside Server/mainline. However, this doesn't seem to work like I would have expected, and I've ended up adding a line for every project like:

-//Server/mainline/projectA/target/...  //Svend_Hansen_Server/projectA/target/...
-//Server/mainline/projectB/target/...  //Svend_Hansen_Server/projectB/target/...
...

And similar lines for bin folders, .classpath and .projet files and more.

C) In Perforce there are the rather useful changelists. However, assume I make a group of changes, check them all and put them in a changelist, to then work on something else before submitting that changelist. If I later make a change to one of the files included in the first changelist, that file will still be in that changelist, and I can't just later submit the changelist assuming that it only contains the changes that I originally added (though it will be the same files). In GIT, if you add a file and them make further changes to it, those changes will not have been added (and would still show in a git diff and you wouldn't be able to commit the file without first adding the new changes as well. Of course, this isn't usefull in the same way the changelist can be as you only have one set of added files, but in GIT you can just commit the changes, as that doesn't actually push them. You could them work on other changes before pushing them, but you wouldn't be able to push anything else that you add later, without pushing the former changes as well.

The null character is '\0', not '/0'.

Error Case:

var userListQuery = {
    userId: {
        $in: result
    },
    "isCameraAdded": true
}

( cameraInfo.findtext != "" ) ? searchQuery : userListQuery;

Output:

TypeError: (intermediate value)(intermediate value) is not a function

Fix: You are missing a semi-colon (;) to separate the expressions

userListQuery = {
    userId: {
        $in: result
    },
    "isCameraAdded": true
}; // Without a semi colon, the error is produced

( cameraInfo.findtext != "" ) ? searchQuery : userListQuery;

vec1[i] = vec2[i]

will set the value of vec1[i] to the value of vec2[i]. Nothing is inserted. Your second approach is almost correct. Instead of +i+1 you need just +i

v1.insert(v1.begin()+i, v2[i])

I am just adding this answer for an awkward situation from DB provider.

what happened in our case is the primary and secondary db shifted reversely (primary to secondary and vice versa) and we are getting the same error.

so please check in the configuration settings for database status which may help you.

I have same problem in android os version 4.1.2

add below line to your AndroidManifest.xml below android:label="@string/app_name" in application tag

android:name="android.support.multidex.MultiDexApplication"

This may help some one with same problem.

just look at cv2.randu() or cv.randn(), it's all pretty similar to matlab already, i guess.

let's play a bit ;) :

import cv2
import numpy as np

>>> im = np.empty((5,5), np.uint8) # needs preallocated input image
>>> im
array([[248, 168,  58,   2,   1],  # uninitialized memory counts as random, too ?  fun ;) 
       [  0, 100,   2,   0, 101],
       [  0,   0, 106,   2,   0],
       [131,   2,   0,  90,   3],
       [  0, 100,   1,   0,  83]], dtype=uint8)
>>> im = np.zeros((5,5), np.uint8) # seriously now.
>>> im
array([[0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0]], dtype=uint8)
>>> cv2.randn(im,(0),(99))         # normal
array([[  0,  76,   0, 129,   0],
       [  0,   0,   0, 188,  27],
       [  0, 152,   0,   0,   0],
       [  0,   0, 134,  79,   0],
       [  0, 181,  36, 128,   0]], dtype=uint8)
>>> cv2.randu(im,(0),(99))         # uniform
array([[19, 53,  2, 86, 82],
       [86, 73, 40, 64, 78],
       [34, 20, 62, 80,  7],
       [24, 92, 37, 60, 72],
       [40, 12, 27, 33, 18]], dtype=uint8)

to apply it to an existing image, just generate noise in the desired range, and add it:

img = ...
noise = ...

image = img + noise

Try with the below code it`s working for me.

public static String decrypt(String encrypted) throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, InvalidAlgorithmParameterException, IllegalBlockSizeException, BadPaddingException, UnsupportedEncodingException {
    byte[] key = your Key in byte array;
    byte[] input = salt in byte array;

    SecretKeySpec skeySpec = new SecretKeySpec(key, "AES");
    IvParameterSpec ivSpec = new IvParameterSpec(input);
    Cipher ecipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
    ecipher.init(Cipher.DECRYPT_MODE, skeySpec, ivSpec);

    byte[] raw = Base64.decode(encrypted, Base64.DEFAULT);
    byte[] originalBytes = ecipher.doFinal(raw);

    String original = new String(originalBytes, "UTF8");
    return original;
}

You can use postgresql Cursors

BEGIN;
DECLARE C CURSOR FOR where * FROM msgtable where cdate='18/07/2012';

Then use

FETCH 10 FROM C;

to fetch 10 rows.

Finnish with

COMMIT;

to close the cursor.

But if you need to make a query in different processes, LIMIT and OFFSET as suggested by @Praveen Kumar is better

To find whether no. is prime or not C++:

#include<iostream>
#include<cmath>

using namespace std;
int main(){

int n, counter=0;

cout <<"Enter a number to check whether it is prime or not \n";
cin>>n;

  for(int i=2; i<=n-1;i++) {
    if (n%i==0) {
      cout<<n<<" is NOT a prime number \n";
      break;
    }
    counter++;
                }
    //cout<<"Value n is "<<n<<endl;
    //cout << "number of times counter run is "<<counter << endl;
    if (counter == n-2)
      cout << n<< " is prime \n";
   return 0;
}

HashMap<String, Object> map1 = new HashMap<String, Object>();
Map<String, Object> map2 = new HashMap<String, Object>();  

First of all Map is an interface it has different implementation like - HashMap, TreeHashMap, LinkedHashMap etc. Interface works like a super class for the implementing class. So according to OOP's rule any concrete class that implements Map is a Map also. That means we can assign/put any HashMap type variable to a Map type variable without any type of casting.

In this case we can assign map1 to map2 without any casting or any losing of data -

map2 = map1

Now, it is bundled with Python. You don't need to install it.

pip -V

This is how you can check whether pip is installed or not.

In rare cases, if it is not installed, download the get-pip.py file and run it with Python as

python get-pip.py

The technical definition of an operating system is "a platform that consists of specific set of libraries and infrastructure for applications to be built upon and interact with each other". A kernel is an operating system in that sense.

The end-user definition is usually something around "a software package that provides a desktop, shortcuts to applications, a web browser and a media player". A kernel doesn't match that definition.

So for an end-user a Linux distribution (say Ubuntu) is an Operating System while for a programmer the Linux kernel itself is a perfectly valid OS depending on what you're trying to achieve. For instance embedded systems are mostly just kernel with very small number of specialized processes running on top of them. In that case the kernel itself becomes the OS itself.

I think you can draw the line at what the majority of the applications running on top of that OS do require. If most of them require only kernel, the kernel is the OS, if most of them require X Window System running, then your OS becomes X + kernel.

1. Open SQL Management Studio
2. Expand your database
3. Expand the "Security" Folder
4. Expand "Users"
5. Right click the user (the one that's trying to perform the query) and select Properties.
6. Select page Membership.

7. Make sure you uncheck

   db_denydatareader

   db_denydatawriter

This should go without saying, but only grant the permissions to what the user needs. An easy lazy fix is to check db_owner like I have, but this is not the best security practice.

For the vast majority^[1] of visitors here, the correct and simplest answer to the question "How do I list all remote branches in Git 1.7+?" is:

git branch -r

For a small minority^[1] git branch -r does not work. If git branch -r does not work try:

git ls-remote --heads <remote-name>

If git branch -r does not work, then maybe as Cascabel says "you've modified the default refspec, so that git fetch and git remote update don't fetch all the remote's branches".

^[1] As of the writing of this footnote 2018-Feb, I looked at the comments and see that the git branch -r works for the vast majority (about 90% or 125 out of 140).

If git branch -r does not work, check git config --get remote.origin.fetch contains a wildcard (*) as per this answer

You could use svcutil.exe to generate client code. This would include the definition of the service contract and any data contracts and fault contracts required.

Then, simply delete the client code: classes that implement the service contracts. You'll then need to implement them yourself, in your service.

To check a remote SSH server prior to the first connection, you can give a look at www.server-stats.net/ssh/ to see all SHH keys for the server, as well as from when the key is known.

That's not like an SSL certificate, but definitely a must-do before connecting to any SSH server for the first time.

Dictionaries do not have any inherent order. Or, rather, their inherent order is "arbitrary but not random", so it doesn't do you any good.

In different terms, your d and your e would be exactly equivalent dictionaries.

What you can do here is to use an OrderedDict:

from collections import OrderedDict
d = { '123': { 'key1': 3, 'key2': 11, 'key3': 3 },
      '124': { 'key1': 6, 'key2': 56, 'key3': 6 },
      '125': { 'key1': 7, 'key2': 44, 'key3': 9 },
    }
d_ascending = OrderedDict(sorted(d.items(), key=lambda kv: kv[1]['key3']))
d_descending = OrderedDict(sorted(d.items(), 
                                  key=lambda kv: kv[1]['key3'], reverse=True))

The original d has some arbitrary order. d_ascending has the order you thought you had in your original d, but didn't. And d_descending has the order you want for your e.

If you don't really need to use e as a dictionary, but you just want to be able to iterate over the elements of d in a particular order, you can simplify this:

for key, value in sorted(d.items(), key=lambda kv: kv[1]['key3'], reverse=True):
    do_something_with(key, value)

If you want to maintain a dictionary in sorted order across any changes, instead of an OrderedDict, you want some kind of sorted dictionary. There are a number of options available that you can find on PyPI, some implemented on top of trees, others on top of an OrderedDict that re-sorts itself as necessary, etc.

Yes it is possible

You can do this using only HTML You need to set default select option disabled="" and selected="" and select tag required="". Browser doesn't allow user to submit the form without selecting an option.

<form action="" method="POST">
    <select name="in-op" required="">
        <option disabled="" selected="">Select Option</option>
        <option>Option 1</option>
        <option>Option 2</option>
        <option>Option 3</option>
    </select>
    <input type="submit" value="Submit">
</form>

Check to make sure your environment isn't being picky about your opening tags. My configuration requires:

<?php

If i try to use:

<?

Then I get the same error as you.

Many people on this thread and on google explain very well that attr_accessible specifies a whitelist of attributes that are allowed to be updated in bulk (all the attributes of an object model together at the same time) This is mainly (and only) to protect your application from "Mass assignment" pirate exploit.

This is explained here on the official Rails doc : Mass Assignment

attr_accessor is a ruby code to (quickly) create setter and getter methods in a Class. That's all.

Now, what is missing as an explanation is that when you create somehow a link between a (Rails) model with a database table, you NEVER, NEVER, NEVER need attr_accessor in your model to create setters and getters in order to be able to modify your table's records.

This is because your model inherits all methods from the ActiveRecord::Base Class, which already defines basic CRUD accessors (Create, Read, Update, Delete) for you. This is explained on the offical doc here Rails Model and here Overwriting default accessor (scroll down to the chapter "Overwrite default accessor")

Say for instance that: we have a database table called "users" that contains three columns "firstname", "lastname" and "role" :

SQL instructions :

CREATE TABLE users (
  firstname string,
  lastname string
  role string
);

I assumed that you set the option config.active_record.whitelist_attributes = true in your config/environment/production.rb to protect your application from Mass assignment exploit. This is explained here : Mass Assignment

Your Rails model will perfectly work with the Model here below :

class User < ActiveRecord::Base

end

However you will need to update each attribute of user separately in your controller for your form's View to work :

def update
    @user = User.find_by_id(params[:id])
    @user.firstname = params[:user][:firstname]
    @user.lastname = params[:user][:lastname]

    if @user.save
        # Use of I18 internationalization t method for the flash message
        flash[:success] = t('activerecord.successful.messages.updated', :model => User.model_name.human)
    end

    respond_with(@user)
end

Now to ease your life, you don't want to make a complicated controller for your User model. So you will use the attr_accessible special method in your Class model :

class User < ActiveRecord::Base

  attr_accessible :firstname, :lastname

end

So you can use the "highway" (mass assignment) to update :

def update
    @user = User.find_by_id(params[:id])

    if @user.update_attributes(params[:user])
        # Use of I18 internationlization t method for the flash message
        flash[:success] = t('activerecord.successful.messages.updated', :model => User.model_name.human)
    end

    respond_with(@user)
end

You didn't add the "role" attributes to the attr_accessible list because you don't let your users set their role by themselves (like admin). You do this yourself on another special admin View.

Though your user view doesn't show a "role" field, a pirate could easily send a HTTP POST request that include "role" in the params hash. The missing "role" attribute on the attr_accessible is to protect your application from that.

You can still modify your user.role attribute on its own like below, but not with all attributes together.

@user.role = DEFAULT_ROLE

Why the hell would you use the attr_accessor?

Well, this would be in the case that your user-form shows a field that doesn't exist in your users table as a column.

For instance, say your user view shows a "please-tell-the-admin-that-I'm-in-here" field. You don't want to store this info in your table. You just want that Rails send you an e-mail warning you that one "crazy" ;-) user has subscribed.

To be able to make use of this info you need to store it temporarily somewhere. What more easy than recover it in a user.peekaboo attribute ?

So you add this field to your model :

class User < ActiveRecord::Base

  attr_accessible :firstname, :lastname
  attr_accessor :peekaboo

end

So you will be able to make an educated use of the user.peekaboo attribute somewhere in your controller to send an e-mail or do whatever you want.

ActiveRecord will not save the "peekaboo" attribute in your table when you do a user.save because she don't see any column matching this name in her model.

function isEmpty(obj) {
    if (typeof obj == 'number') return false;
    else if (typeof obj == 'string') return obj.length == 0;
    else if (Array.isArray(obj)) return obj.length == 0;
    else if (typeof obj == 'object') return obj == null || Object.keys(obj).length == 0;
    else if (typeof obj == 'boolean') return false;
    else return !obj;
}

In ES6 with trim to handle whitespace strings:

const isEmpty = value => {
    if (typeof value === 'number') return false
    else if (typeof value === 'string') return value.trim().length === 0
    else if (Array.isArray(value)) return value.length === 0
    else if (typeof value === 'object') return value == null || Object.keys(value).length === 0
    else if (typeof value === 'boolean') return false
    else return !value
}

this is how I do it

function run_ajax(obj) {
    $.ajax({
        type:"POST",
        url: prefix,
        data: obj.pdata,
        dataType: 'json',
        error: function(data) {
            //do error stuff
        },
        success: function(data) {

            if(obj.func){
                obj.func(data); 
            }

        }
    });
}

alert_func(data){
    //do what you want with data
}

var obj= {};
obj.pdata = {sumbit:"somevalue"}; // post variable data
obj.func = alert_func;
run_ajax(obj);

This is what I use to upload the image through upload window:

    //open upload window
    upload.click();

    //put path to your image in a clipboard
    StringSelection ss = new StringSelection("C:\\IMG_3827.JPG");
    Toolkit.getDefaultToolkit().getSystemClipboard().setContents(ss, null);

    //imitate mouse events like ENTER, CTRL+C, CTRL+V
    Robot robot = new Robot();
    robot.keyPress(KeyEvent.VK_ENTER);
    robot.keyRelease(KeyEvent.VK_ENTER);
    robot.keyPress(KeyEvent.VK_CONTROL);
    robot.keyPress(KeyEvent.VK_V);
    robot.keyRelease(KeyEvent.VK_V);
    robot.keyRelease(KeyEvent.VK_CONTROL);
    robot.keyPress(KeyEvent.VK_ENTER);
    robot.keyRelease(KeyEvent.VK_ENTER);

done

Strangely, no one answered the bottom part of the question for years even though this is an important one -- data.frames are simply lists with the right attributes, so if you have large data you don't want to use as.data.frame or similar for a list. It's much faster to simply "turn" a list into a data frame in-place:

attr(df, "row.names") <- .set_row_names(length(df[[1]]))
class(df) <- "data.frame"

This makes no copy of the data so it's immediate (unlike all other methods). It assumes that you have already set names() on the list accordingly.

[As for loading large data into R -- personally, I dump them by column into binary files and use readBin() - that is by far the fastest method (other than mmapping) and is only limited by the disk speed. Parsing ASCII files is inherently slow (even in C) compared to binary data.]

It may be worth noting that auto-indent does not work if there are syntax errors in the document. Get rid of the red squigglies, and THEN try CTRL+K, CTRL+D, whatever...

To get the current time in UTC in Python 3.2+:

>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).isoformat()
'2015-01-27T05:57:31.399861+00:00'

To get local time in Python 3.3+:

>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).astimezone().isoformat()
'2015-01-27T06:59:17.125448+01:00'

Explanation: datetime.now(timezone.utc) produces a timezone aware datetime object in UTC time. astimezone() then changes the timezone of the datetime object, to the system's locale timezone if called with no arguments. Timezone aware datetime objects then produce the correct ISO format automatically.

Make sure that app_offline.htm is in the root of the virtual directory or website in IIS.

To export multiple functions you can just list them like this:

module.exports = {
   function1,
   function2,
   function3
}

And then to access them in another file:

var myFunctions = require("./lib/file.js")

And then you can call each function by calling:

myFunctions.function1
myFunctions.function2
myFunctions.function3

I changed to following and it worked for me

<tr>
    <td bgcolor="#7d9aaa" style="color: #fff; font-size:15px; font-family:Arial, Helvetica, sans-serif; padding: 12px 2px 12px 0px; ">                              
        <table style="width:620px; border:0; text-align:center;" cellpadding="0" cellspacing="0">               
            <td style="font-weight: bold;padding-right:160px;color: #fff">Order Confirmation </td>                    
            <td style="font-weight: bold;width:260px;color: #fff">Your Confirmation number is {{var order.increment_id}} </td>              
        </table>                    
    </td>
</tr>

Update based on Bsalex request what has actually changed. I replaced span tag

<span style="font-weight: bold;padding-right:150px;padding-left: 35px;">Order Confirmation </span>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<span style="font-weight: bold;width:400px;"> Your Confirmation number is {{var order.increment_id}} </span>

with table and td tags as following

   <table style="width:620px; border:0; text-align:center;" cellpadding="0" cellspacing="0"> 
      <td style="font-weight: bold;padding-right:160px;color: #fff">Order Confirmation </td>
      <td style="font-weight: bold;width:260px;color: #fff">Your Confirmation number is {{var order.increment_id}} </td>
   </table>

It's better to add "+" to REGEX condition in order to accept multiple digits (not only one digit):

<input type="text" name="your_field" pattern="[0-9]+">

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

in home directory you will find a file called ".vimrc" in that file add this code "set nu" and save and exit and open new vi file and you will find line numbers on that.

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

In my case, I had the following structure of a project:

When I was running the test, I kept receiving problems with auro-wiring both facade and kafka attributes - error came back with information about missing instances, even though the test and the API classes reside in the very same package. Apparently those were not scanned.

What actually helped was adding @Import annotation bringing the missing classes to Spring classpath and making them being instantiated.

I would do it this way:

try {
  txtProt = (EditText) findViewById(R.id.Protein); // Same
  p = txtProt.getText().toString(); // Same
  protein = Double.parseDouble(p); // Make use of autoboxing.  It's also easier to read.
} catch (NumberFormatException e) {
  // p did not contain a valid double
}

EDIT: "the program force closes immediately without leaving any info in the logcat"

I don't know bout not leaving information in the logcat output, but a force-close generally means there's an uncaught exception - like a NumberFormatException.

You need to use OPENROWSET

The two that come to mind are:

• pyPdf2
• PDFMiner

var monthIndex = 1;
return month = DateTimeFormatInfo.CurrentInfo.GetAbbreviatedMonthName(monthIndex);

You can try this one as well

If you want one element with the corresponding one you could do

Enumerable.Range(0, List1.Count).All(x => List1[x] == List2[x]);

That will return true if every item is equal to the corresponding one on the second list

If that's almost but not quite what you want it would help if you elaborated more.

Your first usage of Map is inside a function in the combat class. That happens before Map is defined, hence the error.

A forward declaration only says that a particular class will be defined later, so it's ok to reference it or have pointers to objects, etc. However a forward declaration does not say what members a class has, so as far as the compiler is concerned you can't use any of them until Map is fully declared.

The solution is to follow the C++ pattern of the class declaration in a .h file and the function bodies in a .cpp. That way all the declarations appear before the first definitions, and the compiler knows what it's working with.

For List:

All SwiftUI's Lists are backed by a UITableViewin iOS. so you need to change the background color of the tableView. But since Color and UIColor values are slightly different, you can get rid of the UIColor.

struct ContentView : View {
    init(){
        UITableView.appearance().backgroundColor = .clear
    }
    
    var body: some View {
        List {
            Section(header: Text("First Section")) {
                Text("First Cell")
            }
            Section(header: Text("Second Section")) {
                Text("First Cell")
            }
        }
        .background(Color.yellow)
    }
}

Now you can use Any background (including all Colors) you want

Also First look at this result:

As you can see, you can set the color of each element in the View hierarchy like this:

struct ContentView: View {
    
    init(){
        UINavigationBar.appearance().backgroundColor = .green 
        //For other NavigationBar changes, look here:(https://stackoverflow.com/a/57509555/5623035)
    }

    var body: some View {
        ZStack {
            Color.yellow
            NavigationView {
                ZStack {
                    Color.blue
                    Text("Some text")
                }
            }.background(Color.red)
        }
    }
}

And the first one is window:

window.backgroundColor = .magenta

The very common issue is we can not remove the background color of SwiftUI's HostingViewController (yet), so we can't see some of the views like navigationView through the views hierarchy. You should wait for the API or try to fake those views (not recommended).

Comparisons are case insensitive when the column uses a collation which ends with _ci (such as the default latin1_general_ci collation) and they are case sensitive when the column uses a collation which ends with _cs or _bin (such as the utf8_unicode_cs and utf8_bin collations).

Check collation

You can check your server, database and connection collations using:

mysql> show variables like '%collation%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | utf8_general_ci   |
| collation_database   | latin1_swedish_ci |
| collation_server     | latin1_swedish_ci |
+----------------------+-------------------+

and you can check your table collation using:

mysql> SELECT table_schema, table_name, table_collation 
       FROM information_schema.tables WHERE table_name = `mytable`;
+----------------------+------------+-------------------+
| table_schema         | table_name | table_collation   |
+----------------------+------------+-------------------+
| myschema             | mytable    | latin1_swedish_ci |

Change collation

You can change your database, table, or column collation to something case sensitive as follows:

-- Change database collation
ALTER DATABASE `databasename` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;

-- or change table collation
ALTER TABLE `table` CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;

-- or change column collation
ALTER TABLE `table` CHANGE `Value` 
    `Value` VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_bin;

Your comparisons should now be case-sensitive.

Another perspective for doing it on Linux... here is how to do it so that the resulting single file contains the decrypted private key so that something like HAProxy can use it without prompting you for passphrase.

openssl pkcs12 -in file.pfx -out file.pem -nodes

Then you can configure HAProxy to use the file.pem file.

This is an EDIT from previous version where I had these multiple steps until I realized the -nodes option just simply bypasses the private key encryption. But I'm leaving it here as it may just help with teaching.

openssl pkcs12 -in file.pfx -out file.nokey.pem -nokeys
openssl pkcs12 -in file.pfx -out file.withkey.pem
openssl rsa -in file.withkey.pem -out file.key
cat file.nokey.pem file.key > file.combo.pem

1. The 1st step prompts you for the password to open the PFX.
2. The 2nd step prompts you for that plus also to make up a passphrase for the key.
3. The 3rd step prompts you to enter the passphrase you just made up to store decrypted.
4. The 4th puts it all together into 1 file.

Then you can configure HAProxy to use the file.combo.pem file.

The reason why you need 2 separate steps where you indicate a file with the key and another without the key, is because if you have a file which has both the encrypted and decrypted key, something like HAProxy still prompts you to type in the passphrase when it uses it.

1. Modify the definition of the function check_me as::

    function check_me(ev) {
   

2. Now you can access the methods and parameters of the event, in your case:

    ev.preventDefault();
   

3. Then, you have to pass the parameter on the onclick in the inline call::

    <button type="button" onclick="check_me(event);">Click Me!</button>
   

A useful link to understand this.

Full example:

<!DOCTYPE html>
<html lang="en">
  <head>
    <script type="text/javascript">
      function check_me(ev) {
        ev.preventDefault();
        alert("Hello World!")
      }
    </script>
  </head>
  <body>
    <button type="button" onclick="check_me(event);">Click Me!</button>
  </body>
</html>

Alternatives (best practices):

Although the above is the direct answer to the question (passing an event object to an inline event), there are other ways of handling events that keep the logic separated from the presentation

A. Using addEventListener:

<!DOCTYPE html>
<html lang="en">
  <head>
  </head>
  <body>
    <button id='my_button' type="button">Click Me!</button>

    <!-- put the javascript at the end to guarantee that the DOM is ready to use-->
    <script type="text/javascript">
      function check_me(ev) {
        ev.preventDefault();
        alert("Hello World!")
      }
      
      <!-- add the event to the button identified #my_button -->
      document.getElementById("my_button").addEventListener("click", check_me);
    </script>
  </body>
</html>

B. Isolating Javascript:

Both of the above solutions are fine for a small project, or a hackish quick and dirty solution, but for bigger projects, it is better to keep the HTML separated from the Javascript.

Just put this two files in the same folder:

• example.html:

<!DOCTYPE html>
<html lang="en">
  <head>
  </head>
  <body>
    <button id='my_button' type="button">Click Me!</button>

    <!-- put the javascript at the end to guarantee that the DOM is ready to use-->
    <script type="text/javascript" src="example.js"></script>
  </body>
</html>

• example.js:

function check_me(ev) {
    ev.preventDefault();
    alert("Hello World!")
}
document.getElementById("my_button").addEventListener("click", check_me);

Although this is an old question, to support answer by user187291

In case of fixed length of desired substring I would use substr() with negative argument for its short and readable syntax

"xxx_456".substr(-3)

For now it is compatible with common browsers and not yet strictly deprecated.

SASS has a built-in rgba() function to evaluate values.

rgba($color, $alpha)

E.g.

rgba(#00aaff, 0.5) => rgba(0, 170, 255, 0.5)

An example using your own variables:

$my-color: #00aaff;
$my-opacity: 0.5;

.my-element {
  color: rgba($my-color, $my-opacity);
}

Outputs:

.my-element {
  color: rgba(0, 170, 255, 0.5);
}

Easy with onclick-function and a javascript link:

<td onclick="location.href='yourpage.html'">go to yourpage</td>

this may help you.

In .cs page,

//Declare a string
   public string usertypeurl = "";
  //check who is the user
       //place your code to check who is the user
       //if it is admin
       usertypeurl = "help/AdminTutorial.html";
       //if it is other 
        usertypeurl = "help/UserTutorial.html";

In .aspx age pass this variabe

  <a href='<%=usertypeurl%>'>Tutorial</a>

The ls command has a parameter -t to sort by time. You can then grab the first (newest) with head -1.

ls -t b2* | head -1

But beware: Why you shouldn't parse the output of ls

My personal opinion: parsing ls is only dangerous when the filenames can contain funny characters like spaces or newlines. If you can guarantee that the filenames will not contain funny characters then parsing ls is quite safe.

If you are developing a script which is meant to be run by many people on many systems in many different situations then I very much do recommend to not parse ls.

Here is how to do it "right": How can I find the latest (newest, earliest, oldest) file in a directory?

unset -v latest
for file in "$dir"/*; do
  [[ $file -nt $latest ]] && latest=$file
done

PowerShell has aliases for several common commands like echo. Type the following in PowerShell:

Get-Alias echo

to get a response:

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Alias           echo -> Write-Output

Even Get-Alias has an alias gal -> Get-Alias. You could write gal echo to get the alias for echo.

gal echo

Other aliases are listed here: https://docs.microsoft.com/en-us/powershell/scripting/learn/using-familiar-command-names?view=powershell-6

cat dir mount rm cd echo move rmdir chdir erase popd sleep clear h ps sort cls history pushd tee copy kill pwd type del lp r write diff ls ren

That is a serverside comment and will not be delivered to the client ... but it's not optional. If you need this to be programmable, then you'll want this answer :-)

Bash does not support multidimensional arrays.

You can simulate it though by using indirect expansion:

#!/bin/bash
declare -a a0=(1 2 3 4)
declare -a a1=(5 6 7 8)
var="a1[1]"
echo ${!var}  # outputs 6

Assignments are also possible with this method:

let $var=55
echo ${a1[1]}  # outputs 55

Edit 1: To read such an array from a file, with each row on a line, and values delimited by space, use this:

idx=0
while read -a a$idx; do
    let idx++;
done </tmp/some_file

Edit 2: To declare and initialize a0..a3[0..4] to 0, you could run:

for i in {0..3}; do
    eval "declare -a a$i=( $(for j in {0..4}; do echo 0; done) )"
done

you can use unfactor() function from "varhandle" package form CRAN:

library("varhandle")

my_iris <- data.frame(Sepal.Length = factor(iris$Sepal.Length),
                      sample_id = factor(1:nrow(iris)))

my_iris <- unfactor(my_iris)

All of the below is copied directly from @TomOnTime's serverfault answer here:

Show lines that only exist in file a: (i.e. what was deleted from a)

comm -23 a b

Show lines that only exist in file b: (i.e. what was added to b)

comm -13 a b

Show lines that only exist in one file or the other: (but not both)

comm -3 a b | sed 's/^\t//'

(Warning: If file a has lines that start with TAB, it (the first TAB) will be removed from the output.)

NOTE: Both files need to be sorted for "comm" to work properly. If they aren't already sorted, you should sort them:

sort <a >a.sorted
sort <b >b.sorted
comm -12 a.sorted b.sorted

If the files are extremely long, this may be quite a burden as it requires an extra copy and therefore twice as much disk space.

Edit: note that the command can be written more concisely using process substitution (thanks to @phk for the comment):

comm -12 <(sort < a) <(sort < b)

on windows 10 using the 64bit insiders edition the command should be:

git config --global core.editor "'C:\Program Files\Microsoft VS Code Insiders\bin\code-insiders.cmd'"

you can also rename the 'code-insiders.cmd' to 'code.cmd' in the 'Program Files' directory, in this way you can now use the command 'code .' to start editing the files on the . directory

What I did is first check what are the running processes by

SELECT * FROM pg_stat_activity WHERE state = 'active';

Find the process you want to kill, then type:

SELECT pg_cancel_backend(<pid of the process>)

This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.

If the process cannot be killed, try:

SELECT pg_terminate_backend(<pid of the process>)

Try this: tar -cf file.tar file-to-compress ; xz -z file.tar

Note:

1. tar.gz and tar.xz are not the same; xz provides better compression.
2. Don't use pipe | because this runs commands simultaneously. Using ; or & executes commands one after another.

This stuff comes from ES file explorer

Just go into this app > settings

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

You can add a click event handler for this:

document.getElementById('button').onclick = function() {
   alert("button was clicked");
}?;?

This will alert when it's clicked, if you want to track it for later, just set a variable to true in that function instead of alerting, or variable++ if you want to count the number of clicks, whatever your ultimate use is. You can see an example here.

Python 3 has the facility of Launching parallel tasks. This makes our work easier.

It has for thread pooling and Process pooling.

The following gives an insight:

ThreadPoolExecutor Example

import concurrent.futures
import urllib.request

URLS = ['http://www.foxnews.com/',
        'http://www.cnn.com/',
        'http://europe.wsj.com/',
        'http://www.bbc.co.uk/',
        'http://some-made-up-domain.com/']

# Retrieve a single page and report the URL and contents
def load_url(url, timeout):
    with urllib.request.urlopen(url, timeout=timeout) as conn:
        return conn.read()

# We can use a with statement to ensure threads are cleaned up promptly
with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
    # Start the load operations and mark each future with its URL
    future_to_url = {executor.submit(load_url, url, 60): url for url in URLS}
    for future in concurrent.futures.as_completed(future_to_url):
        url = future_to_url[future]
        try:
            data = future.result()
        except Exception as exc:
            print('%r generated an exception: %s' % (url, exc))
        else:
            print('%r page is %d bytes' % (url, len(data)))

Another Example

import concurrent.futures
import math

PRIMES = [
    112272535095293,
    112582705942171,
    112272535095293,
    115280095190773,
    115797848077099,
    1099726899285419]

def is_prime(n):
    if n % 2 == 0:
        return False

    sqrt_n = int(math.floor(math.sqrt(n)))
    for i in range(3, sqrt_n + 1, 2):
        if n % i == 0:
            return False
    return True

def main():
    with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
        for number, prime in zip(PRIMES, executor.map(is_prime, PRIMES)):
            print('%d is prime: %s' % (number, prime))

if __name__ == '__main__':
    main()

You can save a page using php, like this:

$_SESSION['current_page'] = $_SERVER['REQUEST_URI']

And return to the page with:

header("Location: ". $_SESSION['current_page'])

You can do it programmatically by reading the java system properties

@Test
public void javaVersion() {
    System.out.println(System.getProperty("java.version"));
    System.out.println(System.getProperty("java.runtime.version"));
    System.out.println(System.getProperty("java.home"));
    System.out.println(System.getProperty("java.vendor"));
    System.out.println(System.getProperty("java.vendor.url"));
    System.out.println(System.getProperty("java.class.path"));
}

This will output somthing like

1.7.0_17
1.7.0_17-b02
C:\workspaces\Oracle\jdk1.7\jre
Oracle Corporation
http://java.oracle.com/
C:\workspaces\Misc\Miscellaneous\bin; ...

The first line shows the version number. You can parse it an see whether it fits your minimun required java version or not. You can find a description for the naming convention here and more infos here.

I found this thread and got bingo. A little more searching turned up this power shell script:

Get-ChildItem .\ -include bin,obj -Recurse | ForEach-Object ($_) { Remove-Item $_.FullName -Force -Recurse }

I thought I'd share, considering that I did not find the answer when I was looking here.

I don't know if this is accurate, but I have found that python/ruby works much better for scripts that have a lot of mathematical computations. Otherwise you have to use dc or some other "arbitrary precision calculator". It just becomes a very big pain. With python you have much more control over floats vs ints and it is much easier to perform a lot of computations and sometimes.

In particular, I would never work with a bash script to handle binary information or bytes. Instead I would use something like python (maybe) or C++ or even Node.JS.

Extending on Tadeck's Django answer above, the use of 'class Meta:' in Django is just normal Python too.

The internal class is a convenient namespace for shared data among the class instances (hence the name Meta for 'metadata' but you can call it anything you like). While in Django it's generally read-only configuration stuff, there is nothing to stop you changing it:

In [1]: class Foo(object):
   ...:     class Meta:
   ...:         metaVal = 1
   ...:         
In [2]: f1 = Foo()
In [3]: f2 = Foo()
In [4]: f1.Meta.metaVal
Out[4]: 1
In [5]: f2.Meta.metaVal = 2
In [6]: f1.Meta.metaVal
Out[6]: 2
In [7]: Foo.Meta.metaVal
Out[7]: 2

You can explore it in Django directly too e.g:

In [1]: from django.contrib.auth.models import User
In [2]: User.Meta
Out[2]: django.contrib.auth.models.Meta
In [3]: User.Meta.__dict__
Out[3]: 
{'__doc__': None,
 '__module__': 'django.contrib.auth.models',
 'abstract': False,
 'verbose_name': <django.utils.functional.__proxy__ at 0x26a6610>,
 'verbose_name_plural': <django.utils.functional.__proxy__ at 0x26a6650>}

However, in Django you are more likely to want to explore the _meta attribute which is an Options object created by the model metaclass when a model is created. That is where you'll find all of the Django class 'meta' information. In Django, Meta is just used to pass information into the process of creating the _meta Options object.

A server socket listens on a single port. All established client connections on that server are associated with that same listening port on the server side of the connection. An established connection is uniquely identified by the combination of client-side and server-side IP/Port pairs. Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.

On the client-side, it is common practice for new outbound connections to use a random client-side port, in which case it is possible to run out of available ports if you make a lot of connections in a short amount of time.

If you want the k-th bit of n, then do

(n & ( 1 << k )) >> k

Here we create a mask, apply the mask to n, and then right shift the masked value to get just the bit we want. We could write it out more fully as:

    int mask =  1 << k;
    int masked_n = n & mask;
    int thebit = masked_n >> k;

You can read more about bit-masking here.

Here is a program:

#include <stdio.h>
#include <stdlib.h>

int *get_bits(int n, int bitswanted){
  int *bits = malloc(sizeof(int) * bitswanted);

  int k;
  for(k=0; k<bitswanted; k++){
    int mask =  1 << k;
    int masked_n = n & mask;
    int thebit = masked_n >> k;
    bits[k] = thebit;
  }

  return bits;
}

int main(){
  int n=7;

  int  bitswanted = 5;

  int *bits = get_bits(n, bitswanted);

  printf("%d = ", n);

  int i;
  for(i=bitswanted-1; i>=0;i--){
    printf("%d ", bits[i]);
  }

  printf("\n");
}

Interfaces don't simulate multiple inheritance. Java creators considered multiple inheritance wrong, so there is no such thing in Java.

If you want to combine the functionality of two classes into one - use object composition. I.e.

public class Main {
    private Component1 component1 = new Component1();    
    private Component2 component2 = new Component2();
}

And if you want to expose certain methods, define them and let them delegate the call to the corresponding controller.

Here interfaces may come handy - if Component1 implements interface Interface1 and Component2 implements Interface2, you can define

class Main implements Interface1, Interface2

So that you can use objects interchangeably where the context allows it.

So in my point of view, you can't get into diamond problem.

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

>>> print int('01010101111',2)
687
>>> print int('11111111',2)
255

Another way.

There are some disadvantages of CLUSTERED INDEXES vs UNIQUE INDEXES.

As already stated, a CLUSTERED INDEX physically orders the data in the table.

This mean that when you have a lot if inserts or deletes on a table containing a clustered index, everytime (well, almost, depending on your fill factor) you change the data, the physical table needs to be updated to stay sorted.

In relative small tables, this is fine, but when getting to tables that have GB's worth of data, and insertrs/deletes affect the sorting, you will run into problems.

Long story short, node draws from V8, which is internally single-threaded. There are ways to work around the constraints for CPU-intensive tasks.

At one point (0.7) the authors tried to introduce isolates as a way of implementing multiple threads of computation, but were ultimately removed: https://groups.google.com/forum/#!msg/nodejs/zLzuo292hX0/F7gqfUiKi2sJ

Here, you have two options to do this :-

1.You can use the unary plus to convert string number into integer.

2.You can also achieve this via parsing the number into corresponding type. i.e parseInt(), parseFloat() etc

.

Now I am going to show you here with the help of examples(Find the sum of two numbers).

Using unary plus operator

<!DOCTYPE html>
<html>
<body>

<H1>Program for sum of two numbers.</H1>
<p id="myId"></p>
<script>
var x = prompt("Please enter the first number.");//prompt will always return string value
var y = prompt("Please enter the second nubmer.");
var z = +x + +y;    
document.getElementById("myId").innerHTML ="Sum of "+x+" and "+y+" is "+z;
</script>
</body>
</html>

Using parsing approach-

<!DOCTYPE html>
<html>
<body>

<H1>Program for sum of two numbers.</H1>
<p id="myId"></p>
<script>
var x = prompt("Please enter the first number.");
var y = prompt("Please enter the second number.");   
var z = parseInt(x) + parseInt(y);
document.getElementById("myId").innerHTML ="Sum of "+x+" and "+y+" is "+z;
</script>
</body>
</html>

After struggling for sometime I found the information in https://tommcfarlin.com/importing-a-large-database/

1. Connect to Mysql (let's use root for both username and password):

   mysql -uroot -proot
   

2. Connect to the database (let's say it is called emptyDatabase (your should get a confirmation message):

   connect emptyDatabase
   

3 Import the source code, lets say the file is called mySource.sql and it is in a folder called mySoureDb under the profile of a user called myUser:

source /Users/myUser/mySourceDB/mySource.sql

Try to run the application with the Ctrl + F5 combination.

very simple example of parallel processing is

from multiprocessing import Process

output1 = list()
output2 = list()
output3 = list()

def yourfunction():
    for j in range(0, 10):
        # calc individual parameter value
        parameter = j * offset
        # call the calculation
        out1, out2, out3 = calc_stuff(parameter=parameter)

        # put results into correct output list
        output1.append(out1)
        output2.append(out2)
        output3.append(out3)

if __name__ == '__main__':
    p = Process(target=pa.yourfunction, args=('bob',))
    p.start()
    p.join()

Just Android studio run 'Run as administrator' it will work

Or verify your package name on google-services.json file

A common space-saving trick is storing boolean values as an Oracle CHAR, rather than NUMBER:

Try passing it directly to the ng-click function:

<div class="col-lg-1 text-center">
    <span class="glyphicon glyphicon-trash" data="{{event.id}}"
          ng-click="deleteEvent(event.id)"></span>
</div>

Then it should be available in your handler:

$scope.deleteEvent=function(idPassedFromNgClick){
    console.log(idPassedFromNgClick);
}

Here's an example

const FindDate = (date, allDate) => {
        
    // moment().diff only works on moment(). Make sure both date and elements in allDate array are in moment format
    let nearestDate = -1; 
    
    allDate.some(d => {
        const currentDate = moment(d)
        const difference = currentDate.diff(d); // Or d.diff(date) depending on what you're trying to find
        if(difference >= 0){
            nearestDate = d
        }
    });
    
    console.log(nearestDate)
}

You should add these styles to a CSS sheet

div .no-padding {
  padding:0;
}

button .full-width{
  width:100%;
  //display:block; //only if you're having issues
}

Then change add the classes to your code

<div class="span9 btn-block no-padding">
    <button class="btn btn-large btn-block btn-primary full-width" type="button">Block level button</button>
</div>

I haven't tested this and I'm not 100% sure what you want, but I think this will get you close.

REPEAT
    ...
UNTIL cond

Is equivalent to

while True:
    ...
    if cond:
        break

To escape you could just use this from Java 1.5:

Pattern.quote("$test");

You will match exacty the word $test

The problem for me was a new server that System.Web.Routing was of version 3.5 while web.config requested version 4.0.0.0. The resolution was

%WINDIR%\Framework\v4.0.30319\aspnet_regiis -i

%WINDIR%\Framework64\v4.0.30319\aspnet_regiis -i

Set the date of the last commit to the current date

GIT_COMMITTER_DATE="$(date)" git commit --amend --no-edit --date "$(date)"

Set the date of the last commit to an arbitrary date

GIT_COMMITTER_DATE="Mon 20 Aug 2018 20:19:19 BST" git commit --amend --no-edit --date "Mon 20 Aug 2018 20:19:19 BST"

Set the date of an arbitrary commit to an arbitrary or current date

Rebase to before said commit and stop for amendment:

1. git rebase <commit-hash>^ -i
2. Replace pick with e (edit) on the line with that commit (the first one)
3. quit the editor (ESC followed by :wq in VIM)
4. Either:

• GIT_COMMITTER_DATE="$(date)" git commit --amend --no-edit --date "$(date)"
• GIT_COMMITTER_DATE="Mon 20 Aug 2018 20:19:19 BST" git commit --amend --no-edit --date "Mon 20 Aug 2018 20:19:19 BST"

While the DateTime.Kind property does not have a setter, the static method DateTime.SpecifyKind creates a DateTime instance with a specified value for Kind.

Altenatively there are several DateTime constructor overloads that take a DateTimeKind parameter

Cygwin can give you this functionality.

@Christoph: just adding someting . i dont think so this is a correct way.to logout at both places at the same time.(<a href="/logout" onclick="FB.logout();">Logout</a>).

Just add id to the anchor tag . <a id='fbLogOut' href="/logout" onclick="FB.logout();">Logout</a>



$(document).ready(function(){

$('#fbLogOut').click(function(e){ 
     e.preventDefault();
      FB.logout(function(response) {
            // user is now logged out
            var url = $(this).attr('href');
            window.location= url;


        });
});});

just change this line

[img setImage:[UIImage imageNamed:@"anyImageName"]];

with following line

img = [UIImage imageNamed:@"anyImageName"];

    [HttpPost]
    public JsonResult ContactAdd(ContactViewModel contactViewModel)
    {
        if (ModelState.IsValid)
        {
            var job = new Job { Contact = new Contact() };

            Mapper.Map(contactViewModel, job);
            Mapper.Map(contactViewModel, job.Contact);

            _db.Jobs.Add(job);

            _db.SaveChanges();

            //you do not even need this line of code,200 is the default for ASP.NET MVC as long as no exceptions were thrown
            //Response.StatusCode = (int)HttpStatusCode.OK;

            return Json(new { jobId = job.JobId });
        }
        else
        {
            Response.StatusCode = (int)HttpStatusCode.BadRequest;
            return Json(new { jobId = -1 });
        }
    }

just do this : (for angular 9)

import { Inject } from '@angular/core';    
import { DOCUMENT } from '@angular/common';

constructor(@Inject(DOCUMENT) private document: Document){ }

someMethode(){ this.document.location.reload(); }

if some directory/folder does not exist but somehow you navigated to that directory in that case you can see this Error,

for example:

• currently, you are in "mno" directory (path = abc/def/ghi/jkl/mno
• run "sudo su" and delete mno
• goto the "ghi" directory and delete "jkl" directory
• now you are in "ghi" directory (path abc/def/ghi)
• run "exit"
• after running the "exit", you will get that Error
• now you will be in "mno"(path = abc/def/ghi/jkl/mno) folder. that does not exist.

so, Generally this Error will show when Directory doesn't exist.

to fix this, simply run "cd;" or you can move to any other directory which exists.

There is one trick with ParameterBag::get() method. You can set $deep parameter to true and access the required deep nested value without extra variable:

$request->request->get('form[some][deep][data]', null, true);

Also you have possibility to set a default value (2nd parameter of get() method), it can avoid redundant isset($form['some']['deep']['data']) call.

This is going to be largely dependent on the RDBMS you're using, and whether a .NET option even exists for that RDBMS.

If you're using SQL Server, use the SqlBulkCopy class.

For other database vendors, try googling for them specifically. For example a search for ".NET Bulk insert into Oracle" turned up some interesting results, including this link back to Stack Overflow: Bulk Insert to Oracle using .NET.

Add produces = "application/json" in @RequestMapping

I needed to throttle low internet on AndroidTV native device and based on what I have read, the most suitable solution was to limit the internet access directly in my router.
Go to router settings (locally it is smth like 192.168.0.1) -> set up DHCP server (if it's not running) -> choose IP address of a device and set the restriction;

Alternatively, just select 'Other Users' one of the element shows on the left hand side bottom of the current schema.

Select what ever the schema you want from the available list.

You can download the needed packages from here and use pip install "Abc.whl" from the directory where you have downloaded the file.

Here's how to implement this from the official page:

http://getbootstrap.com/2.3.2/examples/sticky-footer.html

I just tested it right now and it WORKS GREAT! :)

HTML

<body>

    <!-- Part 1: Wrap all page content here -->
    <div id="wrap">

      <!-- Begin page content -->
      <div class="container">
        <div class="page-header">
          <h1>Sticky footer</h1>
        </div>
        <p class="lead">Pin a fixed-height footer to the bottom of the viewport in desktop browsers with this custom HTML and CSS.</p>
      </div>

      <div id="push"></div>
    </div>

    <div id="footer">
      <div class="container">
        <p class="muted credit">Example courtesy <a href="http://martinbean.co.uk">Martin Bean</a> and <a href="http://ryanfait.com/sticky-footer/">Ryan Fait</a>.</p>
      </div>
    </div>
</body>

The relevant CSS code is this:

/* Sticky footer styles
-------------------------------------------------- */
html,
body {
    height: 100%;
    /* The html and body elements cannot have any padding or margin. */
}

/* Wrapper for page content to push down footer */
#wrap {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    /* Negative indent footer by it's height */
    margin: 0 auto -30px;
}

/* Set the fixed height of the footer here */
#push,
#footer {
    height: 30px;
}

#footer {
    background-color: #f5f5f5;
}

/* Lastly, apply responsive CSS fixes as necessary */
@media (max-width: 767px) {
    #footer {
        margin-left: -20px;
        margin-right: -20px;
        padding-left: 20px;
        padding-right: 20px;
    }
}

Yet another option: Useful for instance when moving between a thrust::device_vector and a thrust::host_vector, where you cannot use the constructor.

std::vector<T> newVector;
newVector.reserve(1000);
std::copy_n(&vec[100000], 1000, std::back_inserter(newVector));

Should also be complexity O(N)

You could combine this with top anwer code

vector<T>::const_iterator first = myVec.begin() + 100000;
vector<T>::const_iterator last = myVec.begin() + 101000;
std::copy(first, last, std::back_inserter(newVector));

I faced the same issue today, and I was able to fix the issue by changing the security settings on the Java Control Panel from HIGH to MEDIUM.

Well, setting the Java Security Setting to MEDIUM permanently is not really recommended as this will allow potentialy malicious software to run on your system and not be blocked. So I suggest after running your applet you may want to change back the setting to HIGH.

Location of the Java Control Panel

Change the setting of the Control Panel

SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows the user to rename a table or to add a new column to an existing table. It is not possible to rename a column, remove a column, or add or remove constraints from a table. But you can alter table column datatype or other property by the following steps.

1. BEGIN TRANSACTION;
2. CREATE TEMPORARY TABLE t1_backup(a,b);
3. INSERT INTO t1_backup SELECT a,b FROM t1;
4. DROP TABLE t1;
5. CREATE TABLE t1(a,b);
6. INSERT INTO t1 SELECT a,b FROM t1_backup;
7. DROP TABLE t1_backup;
8. COMMIT

For more detail you can refer the link.

The answer by Kleist certainly works, but there is an important caveat:

When you write a Makefile manually, you might generate a SRCS variable using a function to select all .cpp and .h files. If a source file is later added, re-running make will include it.

However, CMake (with a command like file(GLOB ...)) will explicitly generate a file list and place it in the auto-generated Makefile. If you have a new source file, you will need to re-generate the Makefile by re-running cmake.

edit: No need to remove the Makefile.

answer with id:

$('#selectBoxId').find('option:eq(0)').attr('selected', true);

Git now has this functionality built in

git check-ignore *

Of course you can change the glob to something like **/*.dll in your case

Git Reference

use menu Project -> Build Settings ->

then remove armv7s from the"valid architectures". If standard has been chosen then delete that and then add armv7.

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

int arr[20] = {0};

C99 [$6.7.8/21]

If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

1. The syntax for specifying url is {% url namespace:url_name %}. So, check if you have added the app_name in urls.py.
2. In my case, I had misspelled the url_name. The urls.py had the following content path('<int:question_id>/', views.detail, name='question_detail') whereas the index.html file had the following entry <li><a href="{% url 'polls:detail' question.id %}">{{ question.question_text }}</a></li>. Notice the incorrect name.

I would also suggest LinqPad as a convenient way to tackle with Linq for both advanced and beginners.

Example:

This is working when i press button to change text language of my TextView.(strings.xml in values-de folder)

String languageToLoad = "de"; // your language
Configuration config = getBaseContext().getResources().getConfiguration();
Locale locale = new Locale(languageToLoad);
Locale.setDefault(locale);
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
recreate();

dict.fromkeys([1, 2, 3, 4])

This is actually a classmethod, so it works for dict-subclasses (like collections.defaultdict) as well. The optional second argument specifies the value to use for the keys (defaults to None.)

Basic program of adding two times:
You can modify hour:min:sec as per your need using if else.
This program shows you how you can add values from two objects and return in another object.

class demo
{private int hour,min,sec;
    void input(int hour,int min,int sec)
    {this.hour=hour;
    this.min=min;
    this.sec=sec;

    }
    demo add(demo d2)//demo  because we are returning object
    {   demo obj=new demo();
    obj.hour=hour+d2.hour;
    obj.min=min+d2.min;
    obj.sec=sec+d2.sec;
    return obj;//Returning object and later on it gets allocated to demo d3                    
    }
    void display()
    {
        System.out.println(hour+":"+min+":"+sec);
    }
    public static  void main(String args[])
    {
        demo d1=new demo();
        demo d2=new demo();
        d1.input(2, 5, 10);
        d2.input(3, 3, 3);
        demo d3=d1.add(d2);//Note another object is created
        d3.display();


    }

}

Modified Time Addition Program

 class demo
{private int hour,min,sec;
void input(int hour,int min,int sec)
{this.hour=(hour>12&&hour<24)?(hour-12):hour;
this.min=(min>60)?0:min;
this.sec=(sec>60)?0:sec;
}
demo add(demo d2)
{ demo obj=new demo();
obj.hour=hour+d2.hour;
obj.min=min+d2.min;
obj.sec=sec+d2.sec;
if(obj.sec>60)
{obj.sec-=60;
obj.min++;
}
if(obj.min>60)
{ obj.min-=60;
obj.hour++;
}
return obj;
}
void display()
{
System.out.println(hour+":"+min+":"+sec);
}
public static void main(String args[])
{
demo d1=new demo();
demo d2=new demo();
d1.input(12, 55, 55);
d2.input(12, 7, 6);
demo d3=d1.add(d2);
d3.display();
}
}

Try with the PyAutoGUI module. It's multiplatform.

pip install pyautogui

And so:

import pyautogui
pyautogui.click(100, 100)

It also has other features:

import pyautogui
pyautogui.moveTo(100, 150)
pyautogui.moveRel(0, 10)  # move mouse 10 pixels down
pyautogui.dragTo(100, 150)
pyautogui.dragRel(0, 10)  # drag mouse 10 pixels down

This is much easier than going through all the win32con stuff.

I had a similar issue and have tried all the answers in this post. The closest I had come to resolving this issue was by combining the Joseph Lust and Paul Crease solutions. I added the backed up pom.xml file after deleting and reimporting the project, and nothing showed up until I deleted the dependency management tag in the pom.xml and magically the dependencies folder was there.

However, it broke up the child POM's since they need the parent pom.xml dependency management to function, and as a result my MVN was not functioning properly on the project either from Eclipse or the command line, giving a broken pom.xml error.

The last solution if all fails, is to manually import the .jar files needed by your project. Right click the project Properties -> Java Build Path -> Libraries and Add external Jar.

If your MVN is working correctly from the command line and you have done a successful build on the project, you will have all the repos needed in your .m2/repository folder. Add all the external jars mentioned in your dependencies tag of pom.xml and you will see a referenced library section in your Eclipse, with all the pesky red errors gone.

This is not the optimal solution, but it will let you work in Eclipse without any errors of missing dependencies, and also allow you to build the Maven project both from Eclipse and command line.

Just add this in the .htaccess file:

DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?/$1 [L,QSA]

By adding 100 to the number, then run a substring function from index 1 to the last position in right.

var dt = new Date();
var month = (100 + dt.getMonth()+1).toString().substr(1, 2);
var day = (100 + dt.getDate()).toString().substr(1, 2);

console.log(month,day);

you will got this result from the date of 2020-11-3

11,03

I hope the answer is useful

I just put the driver files directly into my project to not get any dependency to my local machine.

final File file = new File("driver/chromedriver_2_22_mac");
System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());

driver = new ChromeDriver();

Have a look at Access Modifiers (C# Programming Guide)

Class and Struct Accessibility

Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.

Struct members, including nested classes and structs, can be declared as public, internal, or private. Class members, including nested classes and structs, can be public, protected internal, protected, internal, private protected or private. The access level for class members and struct members, including nested classes and structs, is private by default. Private nested types are not accessible from outside the containing type.

Derived classes cannot have greater accessibility than their base types. In other words, you cannot have a public class B that derives from an internal class A. If this were allowed, it would have the effect of making A public, because all protected or internal members of A are accessible from the derived class.

You can enable specific other assemblies to access your internal types by using the InternalsVisibleToAttribute. For more information, see Friend Assemblies.

Class and Struct Member Accessibility

Class members (including nested classes and structs) can be declared with any of the six types of access. Struct members cannot be declared as protected because structs do not support inheritance.

Normally, the accessibility of a member is not greater than the accessibility of the type that contains it. However, a public member of an internal class might be accessible from outside the assembly if the member implements interface methods or overrides virtual methods that are defined in a public base class.

The type of any member that is a field, property, or event must be at least as accessible as the member itself. Similarly, the return type and the parameter types of any member that is a method, indexer, or delegate must be at least as accessible as the member itself. For example, you cannot have a public method M that returns a class C unless C is also public. Likewise, you cannot have a protected property of type A if A is declared as private.

User-defined operators must always be declared as public and static. For more information, see Operator overloading.

Finalizers cannot have accessibility modifiers.

Other Types

Interfaces declared directly within a namespace can be declared as public or internal and, just like classes and structs, interfaces default to internal access. Interface members are always public because the purpose of an interface is to enable other types to access a class or struct. No access modifiers can be applied to interface members.

Enumeration members are always public, and no access modifiers can be applied.

Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested.

This has been an old question but solution is very simple to that. If you are ever unsure about how to write criterias, joins etc in hibernate then best way is using native queries. This doesn't slow the performance and very useful. Eq. below

    @Query(nativeQuery = true, value = "your sql query")
returnTypeOfMethod methodName(arg1, arg2);

Your project needs to reference assembly System.Web.dll. Server is an object of type HttpServerUtility. Example:

HttpContext.Current.Server.MapPath(path);

What others said is correct but for those who still face the same problem:
In my case it happened because I copied another project n renamed it to something else BUT previous output files in bin folder were still there... And unfortunately, hitting Build -> Clean Solution after renaming the project and its Namespaces doesn't remove them... so deleting them manually solved my problem!

By setting android:maxEms to a given value together with android:layout_weight="1" will cause the TextView to wrap once it reaches the given length of the ems.

I think there is not similar function like data.shape in Spark. But I will use len(data.columns) rather than len(data.dtypes)

The reason why you're getting that error is because you've declared your struct as:

struct {
 char name[32];
 int  size;
 int  start;
 int  popularity;
} stasher_file;

This is not declaring a stasher_file type. This is declaring an anonymous struct type and is creating a global instance named stasher_file.

What you intended was:

struct stasher_file {
 char name[32];
 int  size;
 int  start;
 int  popularity;
};

But note that while Brian R. Bondy's response wasn't correct about your error message, he's right that you're trying to write into the struct without having allocated space for it. If you want an array of pointers to struct stasher_file structures, you'll need to call malloc to allocate space for each one:

struct stasher_file *newFile = malloc(sizeof *newFile);
if (newFile == NULL) {
   /* Failure handling goes here. */
}
strncpy(newFile->name, name, 32);
newFile->size = size;
...

(BTW, be careful when using strncpy; it's not guaranteed to NUL-terminate.)

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

This problem could be solved as mentioned using the .on on jQuery 1.7+ versions.

Unfortunately, this didn't work within my code (and I have 1.11) so I used:

$('body').delegate('.logout-link','click',function() {

http://api.jquery.com/delegate/

As of jQuery 3.0, .delegate() has been deprecated. It was superseded by the .on() method since jQuery 1.7, so its use was already discouraged. For earlier versions, however, it remains the most effective means to use event delegation. More information on event binding and delegation is in the .on() method. In general, these are the equivalent templates for the two methods:

// jQuery 1.4.3+
$( elements ).delegate( selector, events, data, handler );
// jQuery 1.7+
$( elements ).on( events, selector, data, handler );

This comment might help others :) !

Here's another way, which I believe is equivalent to the factor(..) approach:

> df <- data.frame(let=letters[1:5], num=1:5)
> subdf <- df[df$num <= 3, ]

> subdf$let <- subdf$let[ , drop=TRUE]

> levels(subdf$let)
[1] "a" "b" "c"

For UWP:

<ResourceDictionary Source="ms-appx:///##Namespace.External.Assembly##/##FOLDER##/##FILE##.xaml" />

Not necessarily the best practice, but my environment was a local network with several machines which needed access to the selenium.

When running the chromedriver, you can pass through a param like so :

chromedriver --whitelisted-ips=""

This will basically whitelist all IP's, not always an ideal solution of course and be careful with it for production enviornments, but you should be presented with a verbose warning :

Starting ChromeDriver 2.16.333244 (15fb740a49ab3660b8f8d496cfab2e4d37c7e6ca) on port 9515 All remote connections are allowed. Use a whitelist instead!

A work-around at best, but it works.

Relative check-in

To access properties and methods of a parent class use the base keyword. So in your child class LoadData() method you would do this:

public class Child : Parent 
{
    public void LoadData() 
    {
        base.MyMethod(); // call method of parent class
        base.CurrentRow = 1; // set property of parent class
        // other stuff...
    }
}

Note that you would also have to change the access modifier of your parent MyMethod() to at least protected for the child class to access it.

You can break nested for loops with the word 'break', it works without any labels.

In your case you need to have a condition which is sufficient to break a loop.

Here's an example:

var arr = [[1,3], [5,6], [9,10]];
for (var a = 0; a<arr.length; a++ ){
  for (var i=0; i<arr[a].length; i++) {
    console.log('I am a nested loop and i = ' + i);
    if (i==0) { break; }
  }
  console.log('first loop continues');
}

It logs the following:

> I am a nested loop and i = 0 
> first loop continues
> I am a nested loop and i = 0 
> first loop continues
> I am a nested loop and i = 0 
> first loop continues

The return; statement does not work in this case. Working pen

In short I would say no, the juice is not worth the squeeze to test a service method with a single line that retrieves model data. In my experience people who are new to TDD want to test absolutely everything. The old chestnut of abstracting a facade to a 3rd party framework just so you can create a mock of that frameworks API with which you bastardise/extend so that you can inject dummy data is of little value in my mind. Everyone has a different view of how much unit testing is best. I tend to be more pragmatic these days and ask myself if my test is really adding value to the end product, and at what cost.

 WebConfigurationManager.ConnectionStrings["YourConnectionString"].ProviderName;

Your best bet is probably waitForCondition and writing a javascript function that returns true when the map is loaded.

Replace with

imageWidth = 1 * Convert.ToInt32(Label1.Text);

Please, note that Open and Close the connection is not necessary when using DataAdapter.

So I suggest please update this code and remove the open and close of the connection:

        SqlDataAdapter adapt = new SqlDataAdapter(cmd);

conn.Open(); // this line of code is uncessessary

        Console.WriteLine("connection opened successfuly");
        adapt.Fill(table);

conn.Close(); // this line of code is uncessessary

        Console.WriteLine("connection closed successfuly");

Reference Documentation

The code shown in this example does not explicitly open and close the Connection. The Fill method implicitly opens the Connection that the DataAdapter is using if it finds that the connection is not already open. If Fill opened the connection, it also closes the connection when Fill is finished. This can simplify your code when you deal with a single operation such as a Fill or an Update. However, if you are performing multiple operations that require an open connection, you can improve the performance of your application by explicitly calling the Open method of the Connection, performing the operations against the data source, and then calling the Close method of the Connection. You should try to keep connections to the data source open as briefly as possible to free resources for use by other client applications.

You can concat many kind of expression by sorrounding your simple/complex expression between || characters:

<p th:text="|${bean.field} ! ${bean.field}|">Static content</p>

I dissent from both the answers. Don't create a reference at all, but use late binding:

  Dim objExcelApp As Object
  Dim wb As Object

  Sub Initialize()
    Set objExcelApp = CreateObject("Excel.Application")
  End Sub

  Sub ProcessDataWorkbook()
     Set wb = objExcelApp.Workbooks.Open("path to my workbook")
     Dim ws As Object
     Set ws = wb.Sheets(1)

     ws.Cells(1, 1).Value = "Hello"
     ws.Cells(1, 2).Value = "World"

     'Close the workbook
     wb.Close
     Set wb = Nothing
  End Sub

You will note that the only difference in the code above is that the variables are all declared as objects and you instantiate the Excel instance with CreateObject().

This code will run no matter what version of Excel is installed, while using a reference can easily cause your code to break if there's a different version of Excel installed, or if it's installed in a different location.

Also, the error handling could be added to the code above so that if the initial instantiation of the Excel instance fails (say, because Excel is not installed or not properly registered), your code can continue. With a reference set, your whole Access application will fail if Excel is not installed.

Alternate option using System.Text.Json

For .Net Core one can also use the System.Text.Json namespace and parse using the JsonDocument. Example is an extension method based on the namespace operations:

public static bool IsJsonValid(this string txt)
{
    try { return JsonDocument.Parse(txt) != null; } catch {}

    return false;
}

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

From Apple Docs

You can use subscript syntax to retrieve a value from the dictionary for a particular key. Because it is possible to request a key for which no value exists, a dictionary’s subscript returns an optional value of the dictionary’s value type. If the dictionary contains a value for the requested key, the subscript returns an optional value containing the existing value for that key. Otherwise, the subscript returns nil:

https://developer.apple.com/documentation/swift/dictionary

if let airportName = airports["DUB"] {
    print("The name of the airport is \(airportName).")
} else {
    print("That airport is not in the airports dictionary.")
}
// prints "The name of the airport is Dublin Airport."

From http://www.faqs.org/docs/diveintopython/fileinfo_private.html

Strictly speaking, private methods are accessible outside their class, just not easily accessible. Nothing in Python is truly private; internally, the names of private methods and attributes are mangled and unmangled on the fly to make them seem inaccessible by their given names. You can access the __parse method of the MP3FileInfo class by the name _MP3FileInfo__parse. Acknowledge that this is interesting, then promise to never, ever do it in real code. Private methods are private for a reason, but like many other things in Python, their privateness is ultimately a matter of convention, not force.

The problem is not with the splitting but rather with the WriteLine. A \n in a string printed with WriteLine will produce an "extra" line.

Example

var text = 
  "somet interesting text\n" +
  "some text that should be in the same line\r\n" +
  "some text should be in another line";

string[] stringSeparators = new string[] { "\r\n" };
string[] lines = text.Split(stringSeparators, StringSplitOptions.None);
Console.WriteLine("Nr. Of items in list: " + lines.Length); // 2 lines
foreach (string s in lines)
{
   Console.WriteLine(s); //But will print 3 lines in total.
}

To fix the problem remove \n before you print the string.

Console.WriteLine(s.Replace("\n", ""));

You could definitely use the attributes to return all attributes but you could add an instance method to Post, call it "to_hash" and have it return the data you would like in a hash. Something like

def to_hash
 { name: self.name, active: true }
end

I actually just overwrite anything I want to change in the site.css, you should load the site.css after bootstrap so it will overwrite the classes. What I have done now is just made my own classes with my own little bootstrap theme. Little things like this

.navbar-nav li a{
    color: #fff;
    font-size: 15px;
    margin-top: 9px;
}
.navbar-nav li a:hover{

    background-color: #18678E;
    height: 61px;
}

I also changed the likes of the validations errors the same way.

can be used also like that:

dirname(dirname(abspath(__file__)))

img.UriSource = new Uri("pack://application:,,,/images/" + fileName, UriKind.Absolute);

My requirement was slightly different but used two data sources.

I have used two data sources for same JPA entities from same package. One for executing DDL at the server startup to create/update tables and another one is for DML at runtime.

The DDL connection should be closed after DDL statements are executed, to prevent further usage of super user previlleges anywhere in the code.

As myJSON is an object you can just set its properties, for example:

myJSON.list1 = ["1","2"];

If you dont know the name of the properties, you have to use the array access syntax:

myJSON['list'+listnum] = ["1","2"];

If you want to add an element to one of the properties, you can do;

myJSON.list1.push("3");

Try this regexp

^\s*(for|while)\s*
\(
(?P<balanced>
[^()]*
|
(?P=balanced)
\)
\s*;\s

I removed the wrapping \( \) around (?P=balanced) and moved the * to behind the any not paren sequence. I have had this work with boost xpressive, and rechecked that website (Xpressive) to refresh my memory.
