You can try to use CDATA to put all your symbols that don't work.

An example of something that will work in XML:

<![CDATA[
function matchwo(a,b) {
    if (a < b && a < 0) {
        return 1;
   } else {
       return 0;
   }
}
]]>

And of course you can use < and >.

The clone is a shallow copy of the array.

This test code prints:

[1, 2] / [1, 2]
[100, 200] / [100, 2]

because the MutableInteger is shared in both arrays as objects[0] and objects2[0], but you can change the reference objects[1] independently from objects2[1].

import java.util.Arrays;

This has been mentioned in comments and is hard to find in one of the answers so:

If you are using display: flex for whatever reason, you can instead use:

div {
    display: inline-flex;
}

This is also widely supported across browsers.

The solutions here didn't work for me as I'm styling react components.

What worked though for the sidebar was

.sidebar{
position: sticky;
top: 0;
}

Hope this helps someone.

Try this on your TA:

# Simulate multiplying two N-bit two's-complement numbers
# into a 2N-bit accumulator
# Use shift-add so that it's O(base_2_log(N)) not O(N)

for numa, numb in ((3, 5), (-3, 5), (3, -5), (-3, -5), (-127, -127)):
    print numa, numb,
    accum = 0
    negate = False
    if numa < 0:
        negate = True
        numa = -numa
    while numa:
        if numa & 1:
            accum += numb
        numa >>= 1
        numb <<= 1
    if negate:
        accum = -accum
    print accum

output:

3 5 15
-3 5 -15
3 -5 -15
-3 -5 15
-127 -127 16129

You can format C++ output in cout using iomanip header file. Make sure that you include iomanip header file before you use any of the helper functions like setprecision, setfill etc.

Here is a code snippet I have used in the past to print the average waiting time in the vector, which I have "accumulated".

#include<iomanip>
#include<iostream>
#include<vector>
#include<numeric>

...

cout<< "Average waiting times for tasks is " << setprecision(4) << accumulate(all(waitingTimes), 0)/double(waitingTimes.size()) ;
cout << " and " << Q.size() << " tasks remaining" << endl;

Here is a brief description of how we can format C++ streams. http://www.cprogramming.com/tutorial/iomanip.html

The answer to my comment above on the Original Question makes me think this is all he wants:

loopnum = 0
word = 'afrykanerskojezyczny'
wordlist = ['afrykanerskojezycznym','afrykanerskojezyczni','nieafrykanerskojezyczni']
for i in wordlist:
    wordlist[loopnum] = word
    loopnum += 1

This will do the following:

For every value in wordlist, set that value of the wordlist to the origional code.

All you have to do is put this piece of code where you need to change wordlist, making sure you store the words you need to change in wordlist, and that the original word is correct.

Hope this helps!

As of OSX 10.10 (Yosemite) and since at least OS X 10.8 (Mountain Lion), the behavior is as follows when you open (double-click) executable scripts from Finder:

• Executable scripts^[1] with either NO suffix or suffix .command:
• are executed by default - no setup required:
  • a new Terminal window opens in which the script runs.
  • by default, the window will remain open after the script terminates so you can inspect the output (though at that point the shell that ran the script has exited and you cannot interact with it any longer).
    However, via Terminal's Preferences... > Profiles you can opt to automatically close the window when the script exits.
• Caveat: the working folder is invariably the current user's home folder, NOT the folder in which the script is located.
  • To make a shell script change to the folder in which it is located, place
    • cd -- "$(dirname "$BASH_SOURCE")" right after the shebang line
    • or, if you must remain POSIX-compliant, cd -- "$(dirname "$0")".
    • For edge cases, such as finding a symlinked script's true source directory, see this answer.
• If the script is unexpectedly not executable:
  • Make it executable by running chmod +x <script> in Terminal; otherwise, you'll see the following symptoms:
  • .command: Finder displays a misleading error message that suggests the problem can be fixed via File > Get Info, which is not true - use the chmod +x method suggested above.
  • no suffix:
    • with a shebang line (e.g., #!/bin/bash): behavior is as if the suffix were .sh - see below.
    • with no shebang line: opens in your default text editor (which is TextEdit by default).
• Scripts with suffix .sh, whether executable or not:
• are opened for editing in TextEdit.app or, if installed, with Xcode.app.
• Scripts with suffix .scpt or .applescript (even if they're themselves marked as executable, which is not normally the case):
  • opened for editing in [Apple]Script Editor
  • Note that the JXA source-code files seem to have no distinct suffix (yet).
• Scripts with a custom suffix (a suffix not yet known to the system), whether executable or not (in fact, applies to any kind of file):
  • prompt you for the app to open them with when you first open them, and remember that choice.

^{[1] Executable means: a script with the executable permission bit(s) set and the calling user - relative to the ownership to the file - therefore potentially being allowed to execute it.
If you use chmod a+x to set all permission bits (which is typical), anyone can invoke it (assuming they're also allowed to read the file based on the read permission bit(s) and the file's ownership).}

Since event.keyCode is deprecated, I found the event.key useful in javascript. Below is an example for getting the names of the keyboard keys pressed (using an input element). They are given as a KeyboardEvent key text property:

function setMyKeyDownListener() {_x000D_
    window.addEventListener(_x000D_
      "keydown",_x000D_
      function(event) {MyFunction(event.key)}_x000D_
    )_x000D_
}_x000D_
_x000D_
function MyFunction (the_Key) {_x000D_
    alert("Key pressed is: "+the_Key);_x000D_
}

html { font-size: 4vw; background-color: green; color: white; padding: 1em; }

<body onload="setMyKeyDownListener()">_x000D_
    <div>_x000D_
        <input id="MyInputId">_x000D_
    </div>_x000D_
</body>_x000D_
</html>

Type in cmd.exe Powershell -Help and see the examples.

Reason of the error is wrong initialization of the mysqli object. True construction would be like this:

$DBConnect = new mysqli("localhost","root","","Ladle");

I have written a pretty fast method in c# which beats the hell out of the Regex. It is hosted in an article on CodeProject.

Its advantages are, among better performance the ability to replace named and numbered HTML entities (those like & and &203;) and comment blocks replacement and more.

Please read the related article on CodeProject.

Thank you.

Add following configuration to /etc/apache2/apache2.conf

<FilesMatch "\.php$">
    SetHandler application/x-httpd-php
</FilesMatch>

And restart the apache via sudo service apache2 restart

You can just say

callback();

Alternately you can use the call method if you want to adjust the value of this within the callback.

callback.call( newValueForThis);

Inside the function this would be whatever newValueForThis is.

What kind of business data? Trade secrets or just stuff that they don't want people to see but if it got out, it wouldn't be a big deal? If we are talking trade secrets, financial information, customer information and stuff that's generally confidential. Then don't even go down that route.

I'm wondering whether I need to use a secured connection (https) or just the forms authentication is enough.

Use a secure connection all the way.

Do I need to alter the code / Config

Yes. Well may be not. You may want to have an expert do this for you.

Is SSL and https one and the same...

Mostly yes. People usually refer to those things as the same thing.

Do I need to apply with someone to get some license or something.

You probably want to have your certificate signed by a certificate authority. It will cost you or your client a bit of money.

Do I need to make all my pages secured or only the login page...

Use https throughout. Performance is usually not an issue if the site is meant for internal users.

I was searching Internet for answer, but I was not able to get all these points... Any whitepaper or other references would also be helpful...

Start here for some pointers: http://www.owasp.org/index.php/Category:OWASP_Guide_Project

Note that SSL is a minuscule piece of making your web site secure once it is accessible from the internet. It does not prevent most sort of hacking.

I'm the developer of Redux Auth and some of the issues you mentioned have been fixed in the version 2 beta. You can download this off the offcial website with a sample application too.

• Requires autoloading (impeding performance)
• Uses the inherently unsafe concept of 'security questions'. Dealbreaker!

Security questions are now not used and a simpler forgotten password system has been put in place.

• Return types are a bit of a hodgepodge of true, false, error and success codes

This was fixed in version 2 and returns boolean values. I hated the hodgepodge as much as you.

• Doesn't hook into CI's validation system

The sample application uses the CI's validation system.

• Doesn't allow a user to resend a 'lost password' code

Work in progress

I also implemented some other features such as email views, this gives you the choice of being able to use the CodeIgniter helpers in your emails.

It's still a work in progress so if have any more suggestions please keep them coming.

Ps : Thanks for recommending Redux.

There are at least 2 different methods of invoking functions on radio button selection:

1) Using ng-change directive:

<input type="radio" ng-model="value" value="foo" ng-change='newValue(value)'>

and then, in a controller:

$scope.newValue = function(value) {
     console.log(value);
}

Here is the jsFiddle: http://jsfiddle.net/ZPcSe/5/

2) Watching the model for changes. This doesn't require anything special on the input level:

<input type="radio" ng-model="value" value="foo">

but in a controller one would have:

$scope.$watch('value', function(value) {
       console.log(value);
 });

And the jsFiddle: http://jsfiddle.net/vDTRp/2/

Knowing more about your the use case would help to propose an adequate solution.

 Fragment fr = new Fragment_class();
             FragmentManager fm = getFragmentManager();
            FragmentTransaction fragmentTransaction = fm.beginTransaction();
            fragmentTransaction.add(R.id.viewpagerId, fr);
            fragmentTransaction.commit();

Just to be precise, R.id.viewpagerId is cretaed in your current class layout, upon calling, the new fragment automatically gets infiltrated.

You haven't defined NextActivity in the AndroidManifest.xml file.

Add these lines in android manifest after</activity> tag. It should work.

<activity
    android:name=".NextActivity" >
</activity>

final code will be

<application
    android:allowBackup="true"
    android:icon="@drawable/app_icon"
    android:label="@string/app_name" >
    <activity
        android:name=".MainActivity"
        android:label="Main Activity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".NextActivity" >
    </activity>
</application>

Well Thanks to JeanPaul A. and rdanielmurphy. I had made my own Custom directive for limiting input field to number only. Also added the max and min input attributes. Will work in angular 7 also.

Angular

    import { Directive, ElementRef, Input, HostListener } from '@angular/core';

@Directive({
  selector: '[appNumberOnly]'
})
export class NumberOnlyDirective {
  // Allow decimal numbers. The \. is only allowed once to occur
  private regex: RegExp = new RegExp(/^[0-9]+(\.[0-9]*){0,1}$/g);

  // Allow key codes for special events. Reflect :
  // Backspace, tab, end, home
  private specialKeys: Array<string> = ['Backspace', 'Tab', 'End', 'Home'];
  constructor(private el: ElementRef) { }

  @Input() maxlength: number;
  @Input() min: number;
  @Input() max: number;

  @HostListener('keydown', ['$event'])
  onKeyDown(event: KeyboardEvent) {
    // Allow Backspace, tab, end, and home keys
    if (this.specialKeys.indexOf(event.key) !== -1) {
      return;
    }

    // Do not use event.keycode this is deprecated.
    // See: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode
    const current: string = this.el.nativeElement.value;

    // We need this because the current value on the DOM element
    // is not yet updated with the value from this event
    const next: string = current.concat(event.key);
    if (next && !String(next).match(this.regex) || (this.maxlength && next.length > this.maxlength) ||
      (this.min && +next < this.min) ||
      (this.max && +next >= this.max)) {
      event.preventDefault();
    }
  }

  @HostListener('paste', ['$event']) onPaste(event) {
    // Don't allow pasted text that contains non-numerics
    const pastedText = (event.originalEvent || event).clipboardData.getData('text/plain');

    if (pastedText) {
      const regEx = new RegExp('^[0-9]*$');
      if (!regEx.test(pastedText) || (this.maxlength && pastedText.length > this.maxlength) ||
        (this.min && +pastedText < this.min) ||
        (this.max && +pastedText >= this.max)) {
        event.preventDefault();
      }
    }
  }

}

HTML

<input type="text" class="text-area" [(ngModel)]="itemName" maxlength="3" appNumberOnly />

I know a way without jQuery:

document.getElementById("element-id").scrollIntoView();

Edit: It's been two years and I'm still randomly getting reputation from this post lmao

Edit 2: Please don't edit my comment without asking me.

None of these will allow you to compile PHP with cURL enabled.

In order to compile with cURL, you need libcurl header files (.h files). They are usually found in /usr/include/curl. They generally are bundled in a separate development package.

Per example, to install libcurl in Ubuntu:

sudo apt-get install libcurl4-gnutls-dev

Or CentOS:

sudo yum install curl-devel

Then you can just do:

./configure --with-curl # other options...

If you compile cURL manually, you can specify the path to the files without the lib or include suffix. (e.g.: /usr/local if cURL headers are in /usr/local/include/curl).

You can also install json-py from here http://sourceforge.net/projects/json-py/

For those arriving here from google, I've eventually come across this SO question, and this specific answer solved my problem. I've contacted Microsoft for the hotfix through the live chat on support.microsoft.com and they sent me a link to the hotfix by email.

FragmentTabHost is also an option.

This code is from Android developer's site:

/**
 * This demonstrates how you can implement switching between the tabs of a
 * TabHost through fragments, using FragmentTabHost.
 */
public class FragmentTabs extends FragmentActivity {
    private FragmentTabHost mTabHost;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.fragment_tabs);
    mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
    mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);

    mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"),
            FragmentStackSupport.CountingFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("contacts").setIndicator("Contacts"),
            LoaderCursorSupport.CursorLoaderListFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("custom").setIndicator("Custom"),
            LoaderCustomSupport.AppListFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("throttle").setIndicator("Throttle"),
            LoaderThrottleSupport.ThrottledLoaderListFragment.class, null);
    }
}

I create a helper function waitAll, may be it can make it sweeter. It only works in nodejs for now, not in browser chrome.

    //const parallel = async (...items) => {
    const waitAll = async (...items) => {
        //this function does start execution the functions
        //the execution has been started before running this code here
        //instead it collects of the result of execution of the functions

        const temp = [];
        for (const item of items) {
            //this is not
            //temp.push(await item())
            //it does wait for the result in series (not in parallel), but
            //it doesn't affect the parallel execution of those functions
            //because they haven started earlier
            temp.push(await item);
        }
        return temp;
    };

    //the async functions are executed in parallel before passed
    //in the waitAll function

    //const finalResult = await waitAll(someResult(), anotherResult());
    //const finalResult = await parallel(someResult(), anotherResult());
    //or
    const [result1, result2] = await waitAll(someResult(), anotherResult());
    //const [result1, result2] = await parallel(someResult(), anotherResult());

If you're going to go to the effort of making <a> block, why not put <a> inside the div, being a block element it'll give you the same effect.

The icon will adopt the color from value of the color css property of it's parent.

You can either add this directly to the style:

<span class="glyphicon glyphicon-user" style="color:blue"></span>

Or you can add it as a class to your icon and then set the font color to it in CSS

HTML

<span class="glyphicon glyphicon-search"></span>
<span class="glyphicon glyphicon-user blue"></span>
<span class="glyphicon glyphicon-trash"></span>

CSS

.blue {
    color: blue;
}

Try installing flask through the powershell using the following command.

pip install --isolated Flask

This will allow installation to avoide environment variables and user configuration.

You may also use the .jquery property as described here: http://api.jquery.com/jquery-2/

var a = { what: "A regular JS object" },
b = $('body');

if ( a.jquery ) { // falsy, since it's undefined
    alert(' a is a jQuery object! ');    
}

if ( b.jquery ) { // truthy, since it's a string
    alert(' b is a jQuery object! ');
}

I had the same issue. I found that ipython must be running for jupyter notebook to execute. Do the following:

• Go to the folder where you have your ipython notebook(.ipynb)
• Press shift and right click on the empty space then select "open command window here". This will open a command prompt window.
• Type ipython. This will start ipython.
• Open another command prompt window and open jupyter notebook.
• Open your file again and go to cell>>>run cell.

This should work. It worked for me. Cheers!

It is not supported in java as in other language for ex. Kotlin.

In my recent project my task was to clean an entire database by using sql statement and each table having many constraints like Primary Key and Foreign Key. There are more than 1000 tables in database so its not possible to write a delete query on each and ever table.

By using a stored procedure named sp_MSForEachTable which allows us to easily process some code against each and every table in a single database. It means that it is used to process a single T-SQL command or a different T-SQL commands against every table in the database.

So follow the below steps to truncate all tables in a SQL Server Database:

Step 1- Disable all constraints on the database by using below sql query :

EXEC sys.sp_msforeachtable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'

Step 2- Execute a Delete or truncate operation on each table of the database by using below sql command :

EXEC sys.sp_msforeachtable 'DELETE FROM ?'

Step 3- Enable all constraints on the database by using below sql statement:

EXEC sys.sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'

My 2cents, in a single system user you can set the port also on /etc/ssh/ssh_config then rsync will use the port set here

I would highly recommend taking a look at datejs. With it's api, it becomes drop dead simple to add a month (and lots of other date functionality):

var one_month_from_your_date = your_date_object.add(1).month();

What's nice about datejs is that it handles edge cases, because technically you can do this using the native Date object and it's attached methods. But you end up pulling your hair out over edge cases, which datejs has taken care of for you.

Plus it's open source!

In php, we have two option to concatenate table columns.

First Option using Query

In query, CONCAT keyword used to concatenate two columns

SELECT CONCAT(`SUBJECT`,'_', `YEAR`) AS subject_year FROM `table_name`;

Second Option using symbol ( . )

After fetch the data from database table, assign the values to variable, then using ( . ) Symbol and concatenate the values

$subject = $row['SUBJECT'];
$year = $row['YEAR'];
$subject_year = $subject . "_" . $year;

Instead of underscore( _ ) , we will use the spaces, comma, letters,numbers..etc

For those who need the input file to open directly the camera, you just have to declare capture parameter to the input file, like this :

<input type="file" accept="image/*" capture>

I like bobince's answer:

placeholder= '?' # For SQLite. See DBAPI paramstyle.
placeholders= ', '.join(placeholder for unused in l)
query= 'SELECT name FROM students WHERE id IN (%s)' % placeholders
cursor.execute(query, l)

But I noticed this:

placeholders= ', '.join(placeholder for unused in l)

Can be replaced with:

placeholders= ', '.join(placeholder*len(l))

I find this more direct if less clever and less general. Here l is required to have a length (i.e. refer to an object that defines a __len__ method), which shouldn't be a problem. But placeholder must also be a single character. To support a multi-character placeholder use:

placeholders= ', '.join([placeholder]*len(l))

Actually you can use the SqlConnectionStringBuilder class to build your connection string. To build the connection string, you need to instantiate an object from that SqlConnectionStringBuilder and set their properties with the parameters you use to connect to the database. Then you can get the connection string from the ConnectionString property from the SqlConnectionStringBuilder object, as is shown in this example:

For example:

SqlConnectionStringBuilder sConnB = new SqlConnectionStringBuilder ()
    {
        DataSource = "ServerName",
        InitialCatalog = "DatabaseName",
        UserID = "UserName",
        Password = "UserPassword"
    }.ConnectionString

SqlConnection conn = new SqlConnection(sConnB.ConnectionString);

You can either use the new operator to make that directly.

For example:

SqlConnection conn = new SqlConnection(
    new SqlConnectionStringBuilder ()
    {
        DataSource = "ServerName",
        InitialCatalog = "DatabaseName",
        UserID = "UserName",
        Password = "UserPassword"
    }.ConnectionString
);

You can add more parameters to build your connection string. Remember that the parameters are defined by the values setted in the SqlConnectionStringBuilder object properties.

Also you can get the database connection string from the connection of Microsoft Visual Studio with the attached database. When you select the database, in the properties panel is shown the connection string.

The complete list of properties of the SqlConnectionStringBuilder class is listed in this page from the Microsoft MSDN site.

About the default user of SQL Server, sa means "system administrator" and its password varies according the SQL Server version. On this page you can see how the password varies.

SQL Server 2008/R2 Express User: sa Password: [blank password - leave field empty to connect]
SQL Server 201x Express User: sa Password: Password123
SQL Server 20xx Web or Standard User: sa Password: will be the same as your administrator or root user password at the time the VDS was provisioned.

You can log in with the sa user in this login window at the start of SQL Server Database Manager. Like in this image:

Short answer

The Bearer authentication scheme is what you are looking for.

Long answer

Is it related to bears?

Errr... No :)

According to the Oxford Dictionaries, here's the definition of bearer:

bearer _^/'b??r?/
noun

1. A person or thing that carries or holds something.

2. A person who presents a cheque or other order to pay money.

The first definition includes the following synonyms: messenger, agent, conveyor, emissary, carrier, provider.

And here's the definition of bearer token according to the RFC 6750:

1.2. Terminology

Bearer Token

A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

The Bearer authentication scheme is registered in IANA and originally defined in the RFC 6750 for the OAuth 2.0 authorization framework, but nothing stops you from using the Bearer scheme for access tokens in applications that don't use OAuth 2.0.

Stick to the standards as much as you can and don't create your own authentication schemes.

An access token must be sent in the Authorization request header using the Bearer authentication scheme:

2.1. Authorization Request Header Field

When sending the access token in the Authorization request header field defined by HTTP/1.1, the client uses the Bearer authentication scheme to transmit the access token.

For example:

GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer mF_9.B5f-4.1JqM

[...]

Clients SHOULD make authenticated requests with a bearer token using the Authorization request header field with the Bearer HTTP authorization scheme. [...]

In case of invalid or missing token, the Bearer scheme should be included in the WWW-Authenticate response header:

3. The WWW-Authenticate Response Header Field

If the protected resource request does not include authentication credentials or does not contain an access token that enables access to the protected resource, the resource server MUST include the HTTP WWW-Authenticate response header field [...].

All challenges defined by this specification MUST use the auth-scheme value Bearer. This scheme MUST be followed by one or more auth-param values. [...].

For example, in response to a protected resource request without authentication:

HTTP/1.1 401 Unauthorized
WWW-Authenticate: Bearer realm="example"

And in response to a protected resource request with an authentication attempt using an expired access token:

HTTP/1.1 401 Unauthorized
WWW-Authenticate: Bearer realm="example",
                         error="invalid_token",
                         error_description="The access token expired"

EABI = Embedded Application Binary Interface. It is such specifications to which an executable must conform in order to execute in a specific execution environment. It also specifies various aspects of compilation and linkage required for interoperation between toolchains used for the ARM Architecture. In this context when we speak about armeabi we speak about ARM architecture and GNU/Linux OS. Android follows the little-endian ARM GNU/Linux ABI.

armeabi application will run on ARMv5 (e.g. ARM9) and ARMv6 (e.g. ARM11). You may use Floating Point hardware if you build your application using proper GCC options like -mfpu=vfpv3 -mfloat-abi=softfp which tells compiler to generate floating point instructions for VFP hardware and enables the soft-float calling conventions. armeabi doesn't support hard-float calling conventions (it means FP registers are not used to contain arguments for a function), but FP operations in HW are still supported.

armeabi-v7a application will run on Cortex A# devices like Cortex A8, A9, and A15. It supports multi-core processors and it supports -mfloat-abi=hard. So, if you build your application using -mfloat-abi=hard, many of your function calls will be faster.

The AS keyword is to give an ALIAS name to your database table or to table column. In your example, both statement are correct but there are circumstance where AS clause is needed (though the AS operator itself is optional), e.g.

SELECT salary * 2 AS "Double salary" FROM employee;

In this case, the Employee table has a salary column and we just want the double of the salary with a new name Double Salary.

Sorry if my explanation is not effective.

Update based on your comment, you're right, my previous statement was invalid. The only reason I can think of is that the AS clause has been in existence for long in the SQL world that it's been incorporated in nowadays RDMS for backward compatibility..

You don't need any plugin to do so. For instance, if you code JAVA, you can erase trailing whitespaces configuring save actions:

Eclipse 3.6

Preferences -> Java -> Editors -> Save Actions -> Check Perform the selected actions on save -> Check Additional actions -> Click the Configure.. button.

In the Code organizing tab, check Remove trailing whitespace

You can move your files to other folder and then pull whole folder.

adb shell mv /sdcard/mydir/*.jpg /sdcard/tmp # move your jpegs to temporary dir

adb shell mv /sdcard/tmp/* /sdcard/mydir/ # move them back
adb shell rmdir /sdcard/tmp # remove temporary directory

I'd really recommend Scrapy.

Quote from a deleted answer:

• Scrapy crawling is fastest than mechanize because uses asynchronous operations (on top of Twisted).
• Scrapy has better and fastest support for parsing (x)html on top of libxml2.
• Scrapy is a mature framework with full unicode, handles redirections, gzipped responses, odd encodings, integrated http cache, etc.
• Once you are into Scrapy, you can write a spider in less than 5 minutes that download images, creates thumbnails and export the extracted data directly to csv or json.

The correct way to do this is to add the following to the Manifest file:

<activity
    android:name="FULL_NAME_OF_YOUR_ACTIVITY"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

This should be inserted between:

<application> </application>

No need in invalidating caches.

UNIX_TIMESTAMP(ts1) - UNIX_TIMESTAMP(ts2)

If you want an unsigned difference, add an ABS() around the expression.

Alternatively, you can use TIMEDIFF(ts1, ts2) and then convert the time result to seconds with TIME_TO_SEC().

Everyone is right. You can't print an int[] object out directly, but there's also no need to not use an ArrayList of integer arrays.

Using,

Arrays.toString(arl.get(0))

means splitting the String object into a substring if you want to insert anything in between, such as commas.

Here's what I think amv was looking for from an int array viewpoint.

System.out.println("Arraylist contains: " 
    + arl.get(0)[0] + ", " 
    + arl.get(0)[1] + ", " 
    + arl.get(0)[2]);

This answer is a little late for amv but still may be useful to others.

I just do a remake of RobG solution

if (isLeap) {
  daysInMonth[1] = 29;
}
return theDay <= daysInMonth[--theMonth]

Complete code to disable SSL hostname verifier,

RestTemplate restTemplate = new RestTemplate();
//to disable ssl hostname verifier
restTemplate.setRequestFactory(new SimpleClientHttpRequestFactory() {
   @Override
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
        if (connection instanceof HttpsURLConnection) {
            ((HttpsURLConnection) connection).setHostnameVerifier(new NoopHostnameVerifier());
        }
        super.prepareConnection(connection, httpMethod);
    }
});

You can use // instead of single /. That converts to int directly.

If it saves too fast, try this:

    .autosave {display: inline; padding: 0 10px; color:green; font-weight: 400; font-style: italic;}
</style>

<input type="button" value="Save" onclick="save();" />&nbsp;

$('span.autosave').fadeIn("80");
$('span.autosave').delay("400");
$('span.autosave').fadeOut("80");

When you upgrade to the latest version of the gradle in the gradle-wrapper.properties file i.e. distributionUrl=https\://services.gradle.org/distributions/gradle-6.6.1-bin.zip please do not forget to change the gradle version in the build.gradle file as well

Debugging PHP with VSCode using the vscode-php-debug extension

VSCode can now support debugging PHP projects through the marketplace extension vscode-php-debug.

This extension uses XDebug in the background, and allows you to use breakpoints, watches, stack traces and the like:

Installation is straightforward from within VSCode: Summon the command line with F1 and then type ext install php-debug

you can use parent to access the parent page. So to access a function it would be:

var obj = parent.getElementById('foo');

A simple loop should be working:

for file in /var/*
do
    #whatever you need with "$file"
done

See bash filename expansion

I just moved routing modules i.e. say ARoutingModule above FormsModule and ReactiveFormsModule and after CommonModule in imports array of modules.

This isn't strictly SQL language, but in SQL Server if your database collation is case-sensitive, then all table names are case-sensitive.

An alternative in Java 8:

String[] strings = list.stream().toArray(String[]::new);

Since Java 11:

String[] strings = list.toArray(String[]::new);

Be very very careful renaming objects in sql. You can cause dependencies to fail if you are not fully away with what you are doing. Having said that this works easily(too much so) for renaming things provided you have access proper on the environment:

exec sp_rename 'Nameofobject', 'ReNameofobject'

You have three options:

• Use another way to get the file on the server, and use a mysql client on the server
• Use another client to connect to the server and load the data
• Change your PHP settings to allow such huge files. Don't forget to increment the execution time as well.

You need to escape the % with another...

del "D:\TEST\TEST 100%%\Archive*.TXT"

You shouldn't call viewDidLoad method manually, Instead if you want to reload any data or any UI, you can use this:

override func viewDidLoad() {
    super.viewDidLoad();

    let myButton = UIButton()

    // When user touch myButton, we're going to call loadData method
    myButton.addTarget(self, action: #selector(self.loadData), forControlEvents: .TouchUpInside)

    // Load the data
    self.loadData();
}

func loadData() {
    // code to load data from network, and refresh the interface
    tableView.reloadData()
}

Whenever you want to reload the data and refresh the interface, you can call self.loadData()

Don't use @@ERROR, use BEGIN TRY/BEGIN CATCH instead. See this article: Exception handling and nested transactions for a sample procedure:

create procedure [usp_my_procedure_name]
as
begin
    set nocount on;
    declare @trancount int;
    set @trancount = @@trancount;
    begin try
        if @trancount = 0
            begin transaction
        else
            save transaction usp_my_procedure_name;

        -- Do the actual work here

lbexit:
        if @trancount = 0   
            commit;
    end try
    begin catch
        declare @error int, @message varchar(4000), @xstate int;
        select @error = ERROR_NUMBER(), @message = ERROR_MESSAGE(), @xstate = XACT_STATE();
        if @xstate = -1
            rollback;
        if @xstate = 1 and @trancount = 0
            rollback
        if @xstate = 1 and @trancount > 0
            rollback transaction usp_my_procedure_name;

        raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
        return;
    end catch   
end

This is very common error that we face while starting any Project Vue. I spent lot of time to search this error and finally found a Solution. Suppose i have component that is "table.vue",

i.e components/table.vue

In app.js

Vue.component('mytablecomp', require('./components/table.vue').default);

So in in your index.blade file call component as

<mytablecomp></mytablecomp>

Just you need to keep in mind that your component name is in small not in large or camel case. Then my above code will surely work for you.

To get the value of a pointer, just de-reference the pointer.

int *ptr;
int value;
*ptr = 9;

value = *ptr;

value is now 9.

I suggest you read more about pointers, this is their base functionality.

You could hard code it.

<div class="col-md-6" style="background-color:white;">
</div>

If you don't want to change your database schema (and I would not for this simple query) you can just combine them in the filter like this: WHERE (Address1 + Address2) LIKE '%searchstring%'

set scan off; Above command also works.

Somewhere else in your code you have something that looks like this:

round = 42

Then when you write

round((a/b)*0.9*c)

that is interpreted as meaning a function call on the object bound to round, which is an int. And that fails.

The problem is whatever code binds an int to the name round. Find that and remove it.

I have been confronted with the same problem, so I went to :

/xampp/phpmyadmin/config.inc.php

I pasted the password which I had enter earlier then I was able to access phpmyadmin again, there in the privileges tab/ edit/ I chose no password and go then it all came back to life :)

Also you can change the user to admin but your phpmyadmin would be in admin side and your other localhost website will not work either.

The selected answer will work in everything except IE. I wrote a tutorial on how to make it work cross browser = http://www.andy-howard.com/how-to-play-sounds-cross-browser-including-ie/index.html

Here is the function I wrote;

function playSomeSounds(soundPath)
 {

 var trident = !!navigator.userAgent.match(/Trident\/7.0/);
 var net = !!navigator.userAgent.match(/.NET4.0E/);
 var IE11 = trident && net
 var IEold = ( navigator.userAgent.match(/MSIE/i) ? true : false );
 if(IE11 || IEold){
 document.all.sound.src = soundPath;
 }
 else
 {
 var snd = new Audio(soundPath); // buffers automatically when created
 snd.play();
 }
 };

You also need to add the following tag to the html page:

<bgsound id="sound">

Finally you can call the function and simply pass through the path here:

playSomeSounds("sounds/welcome.wav");

I needed to update and add suffix to few rows of the dataframe on conditional basis based on the another column's value of the same dataframe -

I found that the example I was using had an xml document specification on the first line. I was using a stylesheet I got at this blog entry and the first line was

<?xmlversion="1.0"encoding="utf-8"?>

which was causing the error. When I removed that line, so that the stylesheet started with the line

<xsl:stylesheet version="1.0" xmlns:DTS="www.microsoft.com/SqlServer/Dts" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

my transform worked. By the way, that blog post was the first good, easy-to follow example I have found for trying to get information from the XML definition of an SSIS package, but I did have to modify the paths in the example for my SSIS 2008 packages, so you might too. I also created a version to extract the "flow" from the precedence constraints. My final one looks like this:

    <xsl:stylesheet version="1.0" xmlns:DTS="www.microsoft.com/SqlServer/Dts" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="text" encoding="utf-8" />
    <xsl:template match="/">
    <xsl:text>From,To~</xsl:text>
    <xsl:text>
</xsl:text>
    <xsl:for-each select="//DTS:PrecedenceConstraints/DTS:PrecedenceConstraint">
      <xsl:value-of select="@DTS:From"/>
      <xsl:text>,</xsl:text>
      <xsl:value-of select="@DTS:To"/>
       <xsl:text>~</xsl:text>
      <xsl:text>
</xsl:text>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

and gave me a CSV with the tilde as my line delimiter. I replaced that with a line feed in my text editor then imported into excel to get a with look at the data flow in the package.

I think you're looking at the cell-based feeds section in that API doc page. Then you can just use the PUT/ GET requests within your Python script, using either commands.getstatusoutput or subprocess.

Put into css file:

html { background: url(images/bg.jpg) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; } 

URL images/bg.jpg is your background image

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

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

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

root.mainloop()

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

It's the correct way to access linked DB:

EXEC  [ServerName].[DatabaseName].dbo.sp_HelpText 'storedProcName'

But make sure to mention dbo as it owns the sp_helptext.

For me it was a fresh NetCore application that was just not loading via IIS. When run standalone it was OK though.

I removed the <aspNetCore line and then I got a normal error message from IIS saying that NetCoreModule could not be loaded. That module is required to understand this new web.config line.

The error message 0x8007000d actually says that the web.config is malformed and that error shows up before the error loading module making this error message really crap. (and an unfortunate race condition problem)

I installed the NetCoreSDK and stopped and started IIS (restart didnt work)

The NetCore API started working via IIS as expected.

You have uniqid function for unique id

You can add prefix to make it more unique

Source : http://pk1.php.net/uniqid

>Try this its working fine for the multiple output parameter:

CREATE PROCEDURE [endicia].[credentialLookup]
@accountNumber varchar(20),
@login varchar(20) output,
@password varchar(50) output
AS
BEGIN
SET NOCOUNT ON;
SELECT top 1 @login = [carrierLogin],@password = [carrierPassword]
  FROM [carrier_account] where carrierLogin = @accountNumber
  order by clientId, id
END

Try for the result: 
SELECT *FROM [carrier_account] 
DECLARE @login varchar(20),@password varchar(50)
exec [endicia].[credentialLookup] '588251',@login OUTPUT,@password OUTPUT
SELECT 'login'=@login,'password'=@password

You could use position:fixed; to bottom.

eg:

#footer{
 position:fixed;
 bottom:0;
 left:0;
}

it can be useful : If you want to do it with Symfony forms :

 $today = new DateTime('now');
 $formBuilder->add('startDate', DateType::class, array(
                   'widget' => 'single_text',
                   'data'   => new \DateTime(),
                   'attr'   => ['min' => $today->format('Y-m-d')]
                   ));

I know I'm not answering exactly what you want, but I am wondering if you're asking the right question.

Why don't you use either:

1. windows service
2. create a new thread and run your process on that

Those sound like better options if all you want is to run a process.

Why don't you commit the change for a certain bug and create a patch from that commit and its predecessor?

# hackhackhack, fix two unrelated bugs
git add -p                   # add hunks of first bug
git commit -m 'fix bug #123' # create commit #1
git add -p                   # add hunks of second bug
git commit -m 'fix bug #321' # create commit #2

Then, to create the appropriate patches, use git format-patch:

git format-patch HEAD^^

This will create two files: 0001-fix-bug-123.patch and 0002-fix-bug-321.patch

Or you can create separate branches for each bug, so you can merge or rebase bug fixes individually, or even delete them, if they don't work out.

As @Agam said,

You need this statement in your driver file: from AthleteList import AtheleteList

You must be a PHP programmer.

Use a + sign.

System.out.println("Your number is " + theNumber + "!");

I had the same problem and it seems that it is because of the background color of the button. Try changing the background color to another color eg:

android:background="@color/colorActive"

and see if it works. You can then define a style if you want for the button to use.

For any dialog called myDialog, after calling myDialog.show(); you can call:

myDialog.getWindow().getDecorView().getBackground().setColorFilter(new LightingColorFilter(0xFF000000, CUSTOM_COLOR));

where CUSTOM_COLOR is in 8-digit hex format, ex. 0xFF303030. Here, FF is the alpha value and the rest is the color value in hex.

Give the table a class name and then you target the td's with the following:

table.classname td {
    font-size: 90%;
}

Javascript can not directly set session values. For setting session values from javascript I do ajax call as follows.

Check Online

At ASPx file or html,

 <script type="text/javascript">
 $(function(){
   //Getting values from session and saving in javascript variable.
   // But this will be executed only at document.ready.
   var firstName = '<%= Session["FirstName"] ?? "" %>';
   var lastName = '<%= Session["LastName"] ?? "" %>';

   $("#FirstName").val(firstName);
   $("#LastName").val(lastName);

   $('Button').click(function(){
     //Posting values to save in session
     $.post(document.URL+'?mode=ajax', 
     {'FirstName':$("#FirstName").val(),
     'LastName':$("#LastName").val()
     } );
   });

 });

At Server side,

protected void Page_Load(object sender, EventArgs e)
 {
      if(Request.QueryString["mode"] != null && Request.QueryString["mode"] == "ajax")
      {
        //Saving the variables in session. Variables are posted by ajax.
        Session["FirstName"] = Request.Form["FirstName"] ?? "";
        Session["LastName"] = Request.Form["LastName"] ?? "";
      }
 }

For getting session values, as said by Shekhar and Rajeev

var firstName = '<%= Session["FirstName"] ?? "" %>';

Hope this helps.

You can turn on your PHP errors with error_reporting:

error_reporting(E_ALL);
ini_set('display_errors', 'on');

Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:

Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.

You should set display_errors = 1 in your php.ini file and restart the server.

For non-grouped elements, name and id should be same. In this case you gave name as 'sp' and id as 'sp_100'. Don't do that, do it like this:

HTML:

<input type="hidden" id="msg" name="msg" value="" style="display:none"/>
<input type="checkbox" name="sp" value="100" id="sp">

Javascript:

var Msg="abc";
document.getElementById('msg').value = Msg;
document.getElementById('sp').checked = true;

I had the same problem but got round it by setting AutoPostBack to true and in an update panel set the trigger to the dropdownlist control id and event name to SelectedIndexChanged e.g.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" enableViewState="true">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="ddl1" EventName="SelectedIndexChanged" />
        </Triggers>
        <ContentTemplate>
            <asp:DropDownList ID="ddl1" runat="server" ClientIDMode="Static" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true" ViewStateMode="Enabled">
                <asp:ListItem Text="--Please select a item--" Value="0" />
            </asp:DropDownList>
        </ContentTemplate>
    </asp:UpdatePanel>

Use ng-pattern, in this example you can validate a simple patern with 10 numbers, when the patern is not matched ,the message is show and the button is disabled.

 <form  name="phoneNumber">

        <label for="numCell" class="text-strong">Phone number</label>

        <input id="numCell" type="text" name="inputCelular"  ng-model="phoneNumber" 
            class="form-control" required  ng-pattern="/^[0-9]{10,10}$/"></input>
        <div class="alert-warning" ng-show="phoneNumber.inputCelular.$error.pattern">
            <p> write a phone number</p>
        </div>

    <button id="button"  class="btn btn-success" click-once ng-disabled="!phoneNumber.$valid" ng-click="callDigitaliza()">Buscar</button>

Also you can use another complex patern like

^+?\d{1,3}?[- .]?(?(?:\d{2,3}))?[- .]?\d\d\d[- .]?\d\d\d\d$

, for more complex phone numbers

Use asList() method. From java Doc asList

List<String> species = Arrays.asList(speciesArr);

For anyone that stumbles upon this page, none of the solutions here worked for me. I found this is the way to do it (in a batch file):

@for /f "skip=1" %%p in ('wmic cpu get loadpercentage /VALUE') do (
   for /F "tokens=2 delims==" %%J in ("%%p") do echo %%J
)

You could also grab the attributes with the getAttribute() method which will return the value of a specific HTML attribute.

var elem = document.getElementById('the-span');_x000D_
_x000D_
var typeId = elem.getAttribute('data-typeId');_x000D_
var type   = elem.getAttribute('data-type');_x000D_
var points = elem.getAttribute('data-points');_x000D_
var important = elem.getAttribute('data-important');_x000D_
_x000D_
console.log(`typeId: ${typeId} | type: ${type} | points: ${points} | important: ${important}`_x000D_
);

<span data-typeId="123" data-type="topic" data-points="-1" data-important="true" id="the-span"></span>

Try something like this - it works for the cases you have mentioned.

select * from tbl
where answer like '%[0-9]%'
and answer not like '%[:]%'
and answer not like '%[A-Z]%'

Cong Ma does a good job of explaining what __getitem__ is used for - but I want to give you an example which might be useful. Imagine a class which models a building. Within the data for the building it includes a number of attributes, including descriptions of the companies that occupy each floor :

Without using __getitem__ we would have a class like this :

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def occupy(self, floor_number, data):
          self._floors[floor_number] = data
     def get_floor_data(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1.occupy(0, 'Reception')
building1.occupy(1, 'ABC Corp')
building1.occupy(2, 'DEF Inc')
print( building1.get_floor_data(2) )

We could however use __getitem__ (and its counterpart __setitem__) to make the usage of the Building class 'nicer'.

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def __setitem__(self, floor_number, data):
          self._floors[floor_number] = data
     def __getitem__(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1[0] = 'Reception'
building1[1] = 'ABC Corp'
building1[2] = 'DEF Inc'
print( building1[2] )

Whether you use __setitem__ like this really depends on how you plan to abstract your data - in this case we have decided to treat a building as a container of floors (and you could also implement an iterator for the Building, and maybe even the ability to slice - i.e. get more than one floor's data at a time - it depends on what you need.

In my case the problem occured when i forgot to add the =0 on one function in my pure virtual class. It was fixed when the =0 was added. The same as for Frank above.

class ISettings
{
public: 
    virtual ~ISettings() {};
    virtual void OKFunction() =0;
    virtual void ProblemFunction(); // missing =0   
};

class Settings : ISettings
{
    virtual ~Settings() {};
    void OKFunction();
    void ProblemFunction(); 
};

void Settings::OKFunction()
{
    //stuff
}

void Settings::ProblemFunction()
{
    //stuff
}

replace now.getTime() with your long value.

//GET UTC time for current date
        Date now= new Date();
        //LocalDateTime utcDateTimeForCurrentDateTime = Instant.ofEpochMilli(now.getTime()).atZone(ZoneId.of("UTC")).toLocalDateTime();
        LocalDate localDate = Instant.ofEpochMilli(now.getTime()).atZone(ZoneId.of("UTC")).toLocalDate();
        DateTimeFormatter dTF2 = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
        System.out.println(" formats as " + dTF2.format(utcDateTimeForCurrentDateTime));

I think a simple and clean solution is to use pattern validation.

The following pattern will allow a string that starts with white spaces and will not allow a string containing only white spaces:

/^(\s+\S+\s*)*(?!\s).*$/

It can be set when adding the validators for the corresponding control of the form group:

const form = this.formBuilder.group({
            name: ['', [
                Validators.required,
                Validators.pattern(/^(\s+\S+\s*)*(?!\s).*$/)
            ]]
        });

in package.json we have to config like below (works in Linux and Mac OS)

the important thing is "export NODE_ENV=production" after your build commands below is an example:

  "scripts": {
     "start": "export NODE_ENV=production && npm run build && npm run start-server",
     "dev": "export NODE_ENV=dev && npm run build && npm run start-server",
  } 

• for dev environment, we have to hit "npm run dev" command

• for a production environment, we have to hit "npm run start" command

You can do it with a table, like this:

<table width="100%">
  <tr>
    <td style="width: 50%">Left Text</td>
    <td style="width: 50%; text-align: right;">Right Text</td>
  </tr>
</table>

Or, you can do it with CSS like this:

<div style="float: left;">
    Left text
</div>
<div style="float: right;">
    Right text
</div>

After half a day of fiddling with this, found out that PDO had a bug where...

--

//This would run as expected:
$pdo->exec("valid-stmt1; valid-stmt2;");

--

//This would error out, as expected:
$pdo->exec("non-sense; valid-stmt1;");

--

//Here is the bug:
$pdo->exec("valid-stmt1; non-sense; valid-stmt3;");

It would execute the "valid-stmt1;", stop on "non-sense;" and never throw an error. Will not run the "valid-stmt3;", return true and lie that everything ran good.

I would expect it to error out on the "non-sense;" but it doesn't.

Here is where I found this info: Invalid PDO query does not return an error

Here is the bug: https://bugs.php.net/bug.php?id=61613

So, I tried doing this with mysqli and haven't really found any solid answer on how it works so I thought I's just leave it here for those who want to use it..

try{
    // db connection
    $mysqli = new mysqli("host", "user" , "password", "database");
    if($mysqli->connect_errno){
        throw new Exception("Connection Failed: [".$mysqli->connect_errno. "] : ".$mysqli->connect_error );
        exit();
    }

    // read file.
    // This file has multiple sql statements.
    $file_sql = file_get_contents("filename.sql");

    if($file_sql == "null" || empty($file_sql) || strlen($file_sql) <= 0){
        throw new Exception("File is empty. I wont run it..");
    }

    //run the sql file contents through the mysqli's multi_query function.
    // here is where it gets complicated...
    // if the first query has errors, here is where you get it.
    $sqlFileResult = $mysqli->multi_query($file_sql);
    // this returns false only if there are errros on first sql statement, it doesn't care about the rest of the sql statements.

    $sqlCount = 1;
    if( $sqlFileResult == false ){
        throw new Exception("File: '".$fullpath."' , Query#[".$sqlCount."], [".$mysqli->errno."]: '".$mysqli->error."' }");
    }

    // so handle the errors on the subsequent statements like this.
    // while I have more results. This will start from the second sql statement. The first statement errors are thrown above on the $mysqli->multi_query("SQL"); line
    while($mysqli->more_results()){
        $sqlCount++;
        // load the next result set into mysqli's active buffer. if this fails the $mysqli->error, $mysqli->errno will have appropriate error info.
        if($mysqli->next_result() == false){
            throw new Exception("File: '".$fullpath."' , Query#[".$sqlCount."], Error No: [".$mysqli->errno."]: '".$mysqli->error."' }");
        }
    }
}
catch(Exception $e){
    echo $e->getMessage(). " <pre>".$e->getTraceAsString()."</pre>";
}

What about this:

while ($row = mysql_fetch_array($result)) 
{
    $new_array[$row['id']]['id'] = $row['id'];
    $new_array[$row['id']]['link'] = $row['link'];
}

To retrieve link and id:

foreach($new_array as $array)
{       
   echo $array['id'].'<br />';
   echo $array['link'].'<br />';
}

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

Create a function. Functions do specific things, classes are specific things.

Classes often have methods, which are functions that are associated with a particular class, and do things associated with the thing that the class is - but if all you want is to do something, a function is all you need.

Essentially, a class is a way of grouping functions (as methods) and data (as properties) into a logical unit revolving around a certain kind of thing. If you don't need that grouping, there's no need to make a class.

If you're interested in creating a new dict without using intermediary storage: (this is faster, and in my opinion, cleaner than using dict.items())

dic2 = dict(dic0, **dic1)

Or if you're happy to use one of the existing dicts:

dic0.update(dic1)

This topic shows up on the first page of my google result, so here's a little useful tip for new comers.

You could also dump the sql and gzip it in one line:

mysqldump -u [username] -p[password] [database_name] | gzip > [filename.sql.gz]

In our case we experienced this while performing a load test on our app server. The issue turned out that we need to add additional memory to our JVM because it was running out. This resolved the issue.

Try increasing the memory available to the JVM and or monitor the memory usage when you get those errors.

public List<SomeClass> TheMethod(SomeParameter)
{
  using (MyDC TheDC = new MyDC())
  {
     var TheQueryFromDB = (....
                           select new SomeClass{ SomeVariable = ....,
                                        AnotherVariable = ....}
                           ).ToList();

      return TheQueryFromDB.ToList();
    }
}

public class SomeClass{
   public string SomeVariable{get;set}
   public string AnotherVariable{get;set;}
}

Creating your own class and querying for it is the best solution I know.As much as I know you can not use anonymous type return values in another method, because it won't just be recognized.However, they can be used in the same method. I used to return them as IQueryable or IEnumerable, though it still does not let you see what is inside of the anonymous type variable.

I run into something like this before while I was trying to refactor some code, you can check it here : Refactoring and creating separate methods

I resolved this by just running a simple:

git pull

Nothing more. Now it's showing:

# On branch master
nothing to commit, working directory clean

When you add subfolders and files in subfolders the DLL files in Bin folder also may have changed. When I uploaded the updated DLL file in Bin folder it solved the issue. Thanks to Mayank Modi who suggested that or hinted that.

In the same way just get their other numbers using the other "People" references

People.TYPE_HOME
People.TYPE_MOBILE
People.TYPE_OTHER
People.TYPE_WORK

Make sure that st_new.sh does something at the end what you can recognize (like touch /tmp/st_new.tmp when you remove the file first and always start one instance of st_new.sh).
Then make a polling loop. First sleep the normal time you think you should wait, and wait short time in every loop. This will result in something like

max_retry=20
retry=0
sleep 10 # Minimum time for st_new.sh to finish
while [ ${retry} -lt ${max_retry} ]; do
   if [ -f /tmp/st_new.tmp ]; then
      break # call results.sh outside loop
   else
      (( retry = retry + 1 ))
      sleep 1
   fi
done
if [ -f /tmp/st_new.tmp ]; then
   source ../../results.sh 
   rm -f /tmp/st_new.tmp
else
   echo Something wrong with st_new.sh
fi

In my case I forgot to add @RequestBody annotation to the method argument:

public TestController(@RequestBody KeeperClient testClient) {
        TestController.testClient = testClient;
    }

One option is to use an IDE like Spyder which should allow you to interact with your code while debugging (using an IPython console, in fact). In fact, Spyder is very MATLAB-like, which I presume was intentional. That includes variable inspectors, variable editing, built-in access to documentation, etc.

put the id you want to check in jquery is method.

var idcheck = $("selector").is("#id"); 

if(idcheck){ // if the selector contains particular id

// your code if particular Id is there

}
else{
// your code if particular Id is NOT there
}

@swpd's answer improved

I use , as a leader key and ,a shortcut does the trick

Add this line if you prefer ,a shortcut

map <Leader>a :%y+<CR> 

I use Ctrl y shortcut to copy

vmap <C-y> y:call system("xclip -i -selection clipboard", getreg("\""))<CR>:call system("xclip -i", getreg("\""))<CR>

And ,v to paste

nmap <Leader>v :call setreg("\"",system("xclip -o -selection clipboard"))<CR>p

Before using this you have to install xclip

$ sudo apt-get install xclip

Edit: When you use :%y+, it can be only pasted to Vim vim Ctrl+Insert shortcut. And

map <C-a> :%y+<Esc>

is not conflicting any settings in my Vimrc.

I like to create extension

   extension String {

func isValidateEmail() -> Bool {
    let emailFormat = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"
    let emailPredicate = NSPredicate(format:"SELF MATCHES %@", emailFormat)
    return emailPredicate.evaluate(with: self)
}

}

usage:

if emailid.text!.isValidateEmail() == false(){
 //do what ever you want if string is not matched.

}

It's an argument passed to your success function:

$.ajax({
  type: "POST",
  url: "somescript.php",
  datatype: "html",
  data: dataString,
  success: function(data) {
    alert(data);
    }
});

The full signature is success(data, textStatus, XMLHttpRequest), but you can use just he first argument if it's a simple string coming back. As always, see the docs for a full explanation :)

You can also try in a loop:

for col in df.columns: 
    print(col) 

Listed are the steps that could rectify the error:

1. Press Windows+R
2. Type services.msc and strike Enter
3. Find all services
4. Starting with ora start these services and wait!!
5. When your server specific service is initialized (in my case it was orcl)
6. Now run mysql or whatever you are using and start coding.P

I was having this issue when viewing my website on a phone. While I was trying to close the overlay, I was pretty much clicking on anything under the overlay. A solution that I found working for myself is to just add a tag around the entire overlay

You can't verify (with enough accuracy to rely on) if an email actually exists using just a single PHP method. You can send an email to that account, but even that alone won't verify the account exists (see below). You can, at least, verify it's at least formatted like one

if(filter_var($email, FILTER_VALIDATE_EMAIL)) {
    //Email is valid
}

You can add another check if you want. Parse the domain out and then run checkdnsrr

if(checkdnsrr($domain)) {
     // Domain at least has an MX record, necessary to receive email
}

Many people get to this point and are still unconvinced there's not some hidden method out there. Here are some notes for you to consider if you're bound and determined to validate email:

1. Spammers also know the "connection trick" (where you start to send an email and rely on the server to bounce back at that point). One of the other answers links to this library which has this caveat

   Some mail servers will silently reject the test message, to prevent spammers from checking against their users' emails and filter the valid emails, so this function might not work properly with all mail servers.

   In other words, if there's an invalid address you might not get an invalid address response. In fact, virtually all mail servers come with an option to accept all incoming mail (here's how to do it with Postfix). The answer linking to the validation library neglects to mention that caveat.

2. Spam blacklists. They blacklist by IP address and if your server is constantly doing verification connections you run the risk of winding up on Spamhaus or another block list. If you get blacklisted, what good does it do you to validate the email address?

3. If it's really that important to verify an email address, the accepted way is to force the user to respond to an email. Send them a full email with a link they have to click to be verified. It's not spammy, and you're guaranteed that any responses have a valid address.

You can also fix this problem by adding to model (Entity Framework version >= 5)

[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime CreationDate { get; set; }

If an application is designed to start when Windows starts (as opposed to when a user logs in), your only option is to involve a Windows Service. Either write the application as a service, or write a simple service that exists only to launch the application.

Writing services can be tricky, and can impose restrictions that may be unacceptable for your particular case. One common design pattern is a front-end/back-end pair, with a service that does the work and an application front-end that communicates with the service to display information to the user.

On the other hand, if you just want your application to start on user login, you can use methods 1 or 2 that Joel Coehoorn listed.

In golang's wiki it show some tricks for slice, including delete an element from slice.

Link: enter link description here

For example a is the slice which you want to delete the number i element.

a = append(a[:i], a[i+1:]...)

OR

a = a[:i+copy(a[i:], a[i+1:])]

Keyup should suffice if paired with HTML5 input validation/pattern attribute. So, create a pattern (regex) to validate the input and act upon the .checkValidity() status. Something like below could work. In your case you would want a regex to match length. My solution is in use / demo-able online here.

<input type="text" pattern="[a-zA-Z]+" id="my-input">

var myInput = document.getElementById = "my-input";

myInput.addEventListener("keyup", function(){
  if(!this.checkValidity() || !this.value){
    submitButton.disabled = true;
  } else {
    submitButton.disabled = false;
  }
});

Maybe a bit delayed, but technologies have evolved since so there is certainly new info around which draws fresh light on the matter...

As iOS has yet to open up an API for WiFi Direct and Multipeer Connectivity is iOS only, I believe the best way to approach this is to use BLE, which is supported by both platforms (some better than others).

On iOS a device can act both as a BLE Central and BLE Peripheral at the same time, on Android the situation is more complex as not all devices support the BLE Peripheral state. Also the Android BLE stack is very unstable (to date).

If your use case is feature driven, I would suggest to look at Frameworks and Libraries that can achieve cross platform communication for you, without you needing to build it up from scratch.

For example: http://p2pkit.io or google nearby

Disclaimer: I work for Uepaa, developing p2pkit.io for Android and iOS.

Send XML requests with the raw data type, then set the Content-Type to text/xml.

1. After creating a request, use the dropdown to change the request type to POST.

   

2. Open the Body tab and check the data type for raw.

   

3. Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)

   

4. Enter your raw XML data into the input field below

   

5. Click Send to submit your XML Request to the specified server.

   

myLabel.setHorizontalAlignment(SwingConstants.CENTER);
myLabel.setVerticalAlignment(SwingConstants.CENTER);

If you cannot reconstruct the label for some reason, this is how you edit these properties of a pre-existent JLabel.

I would use phpseclib, a pure PHP SSH implementation. An example:

<?php
include('Net/SSH2.php');

$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
    exit('Login Failed');
}

echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>

var mongo = require('mongodb');
var MongoClient = mongo.MongoClient;    
MongoClient.connect('mongodb://'+DATABASEUSERNAME+':'+DATABASEPASSWORD+'@'+DATABASEHOST+':'DATABASEPORT+'/'+DATABASENAME,function(err, db){  
      if(err) 
        console.log(err);
      else
      {
        console.log('Mongo Conn....');

      }
    });
//for local server 
//in local server DBPASSWOAD and DBusername not required
MongoClient.connect('mongodb://'+DATABASEHOST+':'+DATABASEPORT+'/'+DATABASENAME,function(err, db){  
      if(err) 
        console.log(err);
      else
      {
        console.log('Mongo Conn....');

      }
    });

I have faced this problem during development of a E-Commerce site using NopCommerce, I got this solution by 3 different ways as like the previous answers. But according to the NopCommerce structure I didn't found those three at a time. I have just seen that there they are using just [AllowHtml] and it's working fine except any problem. As previously asked question

Personally I don't prefer [ValidateInput(false)] because i's skipping total model entity checking, which is insecure. But if anyone just write have a look here

[AllowHtml] 
public string BlogText {get;set;}

then it just skip only single property, and just allow only particular property and check hardly all other entities. Therefore it seems preferable towards mine.

I will recommend you not to use any third party libraries for auto fetch OTP from SMS Inbox. This can be done easily if you have basic understanding of Broadcast Receiver and how it works. Just Try following approach :

Step 1) Create single interface i.e SmsListner

package com.wnrcorp.reba;
public interface SmsListener{
public void messageReceived(String messageText);}

Step 2) Create single Broadcast Receiver i.e SmsReceiver

package com.wnrcorp.reba;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
public class SmsReceiver extends BroadcastReceiver {
private static SmsListener mListener;
Boolean b;
String abcd,xyz;
@Override
public void onReceive(Context context, Intent intent) {
Bundle data  = intent.getExtras();
Object[] pdus = (Object[]) data.get("pdus");
    for(int i=0;i<pdus.length;i++){
        SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
        String sender = smsMessage.getDisplayOriginatingAddress();
       // b=sender.endsWith("WNRCRP");  //Just to fetch otp sent from WNRCRP
        String messageBody = smsMessage.getMessageBody();
       abcd=messageBody.replaceAll("[^0-9]","");   // here abcd contains otp 
        which is in number format
        //Pass on the text to our listener.
        if(b==true) {
            mListener.messageReceived(abcd);  // attach value to interface 
  object
        }
        else
        {
        }
    }
}
public static void bindListener(SmsListener listener) {
    mListener = listener;
}
}

Step 3) Add Listener i.e broadcast receiver in android manifest file

<receiver android:name=".SmsReceiver">    
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
</receiver>

and add permission

<uses-permission android:name="android.permission.RECEIVE_SMS"/>

Final Step 4) The activity where you going to auto fetch otp when it is received in inbox. In my case I'm fetching otp and setting on edittext field.

public class OtpVerificationActivity extends AppCompatActivity {
EditText ed;
TextView tv;
String otp_generated,contactNo,id1;
GlobalData gd = new GlobalData();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_otp_verification);
    ed=(EditText)findViewById(R.id.otp);
    tv=(TextView) findViewById(R.id.verify_otp); 
    /*This is important because this will be called every time you receive 
     any sms */            
 SmsReceiver.bindListener(new SmsListener() {
        @Override
        public void messageReceived(String messageText) {
            ed.setText(messageText);     
        }
    });
    tv.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            try
            {
                InputMethodManager imm=
  (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);                    
  imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),0);
            }
            catch(Exception e)
            {}           
            if (ed.getText().toString().equals(otp_generated))
            {
                Toast.makeText(OtpVerificationActivity.this, "OTP Verified 
       Successfully !", Toast.LENGTH_SHORT).show();           
             }
    });
   }
}

Screenshots for OTP Verification Activity where you fetch OTP as soons as messages received

@PathVariable - must be placed in the endpoint uri and access the query parameter value from the request
@RequestParam - must be passed as method parameter (optional based on the required property)
 http://localhost:8080/employee/call/7865467

 @RequestMapping(value=“/call/{callId}", method = RequestMethod.GET)
 public List<Calls> getAgentCallById(
            @PathVariable(“callId") int callId,
            @RequestParam(value = “status", required = false) String callStatus) {

    }

http://localhost:8080/app/call/7865467?status=Cancelled

@RequestMapping(value=“/call/{callId}", method = RequestMethod.GET)
public List<Calls> getAgentCallById(
            @PathVariable(“callId") int callId,
            @RequestParam(value = “status", required = true) String callStatus) {

}

It might be easier with vlookup. Try this:

=IFERROR(VLOOKUP(D2,G:H,2,0),"")

The IFERROR() is for no matches, so that it throws "" in such cases.

VLOOKUP's first parameter is the value to 'look for' in the reference table, which is column G and H.

VLOOKUP will thus look for D2 in column G and return the value in the column index 2 (column G has column index 1, H will have column index 2), meaning that the value from column H will be returned.

The last parameter is 0 (or equivalently FALSE) to mean an exact match. That's what you need as opposed to approximate match.

This might be off-topic. But for the wget in for loop, you can certainly do

curl -O http://example.com/search/link[1-600]

Usually, this problem resolve with using the modulo of a number in a loop or convert a number to a string. For convert a number to a string, you may can use the function itoa, so considering the variant with the modulo of a number in a loop.

It's really a 6 of one, a half-dozen of the other situation.

The only possible argument against your approach is $_SERVER['REQUEST_METHOD'] == 'POST' may not be populated on certain web-servers/configuration, whereas the $_POST array will always exist in PHP4/PHP5 (and if it doesn't exist, you have bigger problems (-:)

IMHO the method UserForm_Initialize should remain private bacause it is event handler for Initialize event of the UserForm.

This event handler is called when new instance of the UserForm is created. In this even handler u can initialize the private members of UserForm1 class.

Example:

Standard module code:

Option Explicit

Public Sub Main()
  Dim myUserForm As UserForm1

  Set myUserForm = New UserForm1
  myUserForm.Show

End Sub

User form code:

Option Explicit

Private m_initializationDate As Date

Private Sub UserForm_Initialize()
  m_initializationDate = VBA.DateTime.Date
  MsgBox "Hi from UserForm_Initialize event handler.", vbInformation
End Sub

Since 2014b, Matlab has these normalization routines embedded natively in the histogram function (see the help file for the 6 routines this function offers). Here is an example using the PDF normalization (the sum of all the bins is 1).

data = 2*randn(5000,1) + 5;             % generate normal random (m=5, std=2)
h = histogram(data,'Normalization','pdf')   % PDF normalization

The corresponding PDF is

Nbins = h.NumBins;
edges = h.BinEdges; 
x = zeros(1,Nbins);
for counter=1:Nbins
    midPointShift = abs(edges(counter)-edges(counter+1))/2;
    x(counter) = edges(counter)+midPointShift;
end

mu = mean(data);
sigma = std(data);

f = exp(-(x-mu).^2./(2*sigma^2))./(sigma*sqrt(2*pi));

The two together gives

hold on;
plot(x,f,'LineWidth',1.5)

An improvement that might very well be due to the success of the actual question and accepted answer!

EDIT - The use of hist and histc is not recommended now, and histogram should be used instead. Beware that none of the 6 ways of creating bins with this new function will produce the bins hist and histc produce. There is a Matlab script to update former code to fit the way histogram is called (bin edges instead of bin centers - link). By doing so, one can compare the pdf normalization methods of @abcd (trapz and sum) and Matlab (pdf).

The 3 pdf normalization method give nearly identical results (within the range of eps).

TEST:

A = randn(10000,1);
centers = -6:0.5:6;
d = diff(centers)/2;
edges = [centers(1)-d(1), centers(1:end-1)+d, centers(end)+d(end)];
edges(2:end) = edges(2:end)+eps(edges(2:end));

figure;
subplot(2,2,1);
hist(A,centers);
title('HIST not normalized');

subplot(2,2,2);
h = histogram(A,edges);
title('HISTOGRAM not normalized');

subplot(2,2,3)
[counts, centers] = hist(A,centers); %get the count with hist
bar(centers,counts/trapz(centers,counts))
title('HIST with PDF normalization');


subplot(2,2,4)
h = histogram(A,edges,'Normalization','pdf')
title('HISTOGRAM with PDF normalization');

dx = diff(centers(1:2))
normalization_difference_trapz = abs(counts/trapz(centers,counts) - h.Values);
normalization_difference_sum = abs(counts/sum(counts*dx) - h.Values);

max(normalization_difference_trapz)
max(normalization_difference_sum)

The maximum difference between the new PDF normalization and the former one is 5.5511e-17.

Plain old Java on plain old Java 7 and no other dependencies demonstrates the difference...

I put file.txt in c:\temp\ and I put c:\temp\ on the classpath.

There is only one case where there is a difference between the two call.

class J {

 public static void main(String[] a) {
    // as "absolute"

    // ok   
    System.err.println(J.class.getResourceAsStream("/file.txt") != null); 

    // pop            
    System.err.println(J.class.getClassLoader().getResourceAsStream("/file.txt") != null); 

    // as relative

    // ok
    System.err.println(J.class.getResourceAsStream("./file.txt") != null); 

    // ok
    System.err.println(J.class.getClassLoader().getResourceAsStream("./file.txt") != null); 

    // no path

    // ok
    System.err.println(J.class.getResourceAsStream("file.txt") != null); 

   // ok
   System.err.println(J.class.getClassLoader().getResourceAsStream("file.txt") != null); 
  }
}

Easy solution if you don't want to code manually using Google Sheets Power Tools:

1. Install Power Tools through the Add-ons panel (Add-ons -> Get add-ons)
2. From the Power Tools sidebar click on the S button and within that menu click on the "Sum by Color" menu item
3. Select the "Pattern cell" with the color markup you want to search for
4. Select the "Source range" for the cells you want to count
5. Use function should be set to "COUNTA"
6. Press "Insert function" and you're done :)

As answered by Magus :

Abstract states can be used to add a prefix to all child state urls. But note that abstract still needs a ui-view for its children to populate. To do so you can simply add it inline.

.state('app', {
   url: "/app",
   abstract: true,
   template: '<ui-view/>'
})

For more information see documentation : https://github.com/angular-ui/ui-router/wiki/Nested-States-%26-Nested-Views

If an instance of an object is available, then the simplest way to get its Class is to invoke Object.getClass()

The .class Syntax

If the type is available but there is no instance then it is possible to obtain a Class by appending .class to the name of the type. This is also the easiest way to obtain the Class for a primitive type.

boolean b;
Class c = b.getClass();   // compile-time error

Class c = boolean.class;  // correct

See: docs.oracle.com about class

You're not assigning the parsed float back to your value var:

value = parseFloat(value).toFixed(2);

should fix things up.

Try this

static DataTable ConvertToDatatable(List<Item> list)
{
    DataTable dt = new DataTable();

    dt.Columns.Add("Name");
    dt.Columns.Add("Price");
    dt.Columns.Add("URL");
    foreach (var item in list)
    {
        var row = dt.NewRow();

        row["Name"] = item.Name;
        row["Price"] = Convert.ToString(item.Price);
        row["URL"] = item.URL;

        dt.Rows.Add(row);
    }

    return dt;
}

This answer doesn't help for SQL databases where SharePoint is connected. db_securityadmin is required for the configuration databases. In order to add db_securityadmin, you will need to change the owner of the database to an administrative account. You can use that account just for dbo roles.

Removed the profiles from the directory on your machine: "~/Library/MobileDevice/Provisioning Profiles". And logged to apple developer centre and edited the specific provisioning profile and selected the certificate for provisioning profile and generated the profile again. Installed the new profile and it worked for me.

You could use a Data URI to supply the image data, for example:

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">

<image width="20" height="20" xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=="/>

</svg>

The image will go through all normal svg transformations.

But this technique has disadvantages, for example the image will not be cached by the browser

Unless you're trying to upload the file using ajax, just submit the form to /upload/image.

<form enctype="multipart/form-data" action="/upload/image" method="post">
    <input id="image-file" type="file" />
</form>

If you do want to upload the image in the background (e.g. without submitting the whole form), you can use ajax:

• Asynchronous file upload (AJAX file upload) using jsp and javascript
• jQuery Ajax File Upload
• Ajax using file upload

There is another way if all you want is the text up to the first line feed:

x='some
thing'

y=${x%$'\n'*}

After that y will contain some and nothing else (no line feed).

What is happening here?

We perform a parameter expansion substring removal (${PARAMETER%PATTERN}) for the shortest match up to the first ANSI C line feed ($'\n') and drop everything that follows (*).

If you are getting this error, it could be because you don't have a route defined for your get.

For example:

const express = require('express');

const app = express();

app.get('/people', function (req, res) {
    res.send('hello');
})

app.listen(3000);


http://http://localhost:3000/people --> this works
http://http://localhost:3000 --> this will output Cannot GET / message.

Try using something like this:

<link rel="image_src" href="http://yoursite.com/graphics/yourimage.jpg" /link>`

Seems to work just fine on Firefox as long as you use a full path to your image.

Trouble is it get vertically offset downward for some reason. Image is 200 x 200 as recommended somewhere I read.

If you want to run it @build time :

CMD /bin/bash /file.sh arg1

if you want to run it @run time :

ENTRYPOINT ["/bin/bash"]
CMD ["/file.sh", "arg1"]

Then in the host shell

docker build -t test .
docker run -i -t test

I found this question when searching for You are in 'detached HEAD' state.

After analyzing what I had done to get here, as compared with what I had done in the past, I discovered that I had made a mistake.

My normal flow is:

git checkout master
git fetch
git checkout my-cool-branch
git pull

This time I did:

git checkout master
git fetch
git checkout origin/my-cool-branch
# You are in 'detached HEAD' state.

The problem is that I accidentally did:

git checkout origin/my-cool-branch

Rather than:

git checkout my-cool-branch

The fix (in my situation) was simply to run the above command and then continue the flow:

git checkout my-cool-branch
git pull

If using Xcode 4.2 or higher, try the following:

1. Click your Project name (in the left column), followed by the Target:

   

2. Click the 'Build Settings' tab (in the right column):

   

3. Click the 'Release' or 'Distribution' row under 'Architectures', and choose 'Other...':

   

4. Double click the highlighted row named '$(ARCHS_STANDARD_32_BIT)' in the popover that appears, and replace it by typing 'armv6'. Then add a new row with the plus button in the bottom left of the popover, and type 'armv7', then click Done:

   

Update: you should add armv7s to target the iPhone 5 as well. (And drop armv6 if building with Xcode 4.5 or higher, which no longer supports armv6.)

That's it. You should now be able to build/archive without generating errors.

If it still doesn't work, see this answer from justinxreese, which suggests adding entries for armv6 and armv7 under "Required Device Capabilities" in your info.plist file.

TCO (Tail Call Optimization) is the process by which a smart compiler can make a call to a function and take no additional stack space. The only situation in which this happens is if the last instruction executed in a function f is a call to a function g (Note: g can be f). The key here is that f no longer needs stack space - it simply calls g and then returns whatever g would return. In this case the optimization can be made that g just runs and returns whatever value it would have to the thing that called f.

This optimization can make recursive calls take constant stack space, rather than explode.

Example: this factorial function is not TCOptimizable:

def fact(n):
    if n == 0:
        return 1
    return n * fact(n-1)

This function does things besides call another function in its return statement.

This below function is TCOptimizable:

def fact_h(n, acc):
    if n == 0:
        return acc
    return fact_h(n-1, acc*n)

def fact(n):
    return fact_h(n, 1)

This is because the last thing to happen in any of these functions is to call another function.

In fact, this is a "how to" subject. So, here is the reference implementation:

    public class BOX
    {
        double height, length, breadth;

        public static bool operator == (BOX b1, BOX b2)
        {
            if ((object)b1 == null)
                return (object)b2 == null;

            return b1.Equals(b2);
        }

        public static bool operator != (BOX b1, BOX b2)
        {
            return !(b1 == b2);
        }

        public override bool Equals(object obj)
        {
            if (obj == null || GetType() != obj.GetType())
                return false;

            var b2 = (BOX)obj;
            return (length == b2.length && breadth == b2.breadth && height == b2.height);
        }

        public override int GetHashCode()
        {
            return height.GetHashCode() ^ length.GetHashCode() ^ breadth.GetHashCode();
        }
    }

UPDATE: the cast to (object) in the operator == implementation is important, otherwise, it would re-execute the operator == overload, leading to a stackoverflow. Credits to @grek40.

There is a little hack with php. And it works not only with Google, but with any website you don't control and can't add Access-Control-Allow-Origin *

We need to create PHP-file (ex. getContentFromUrl.php) on our webserver and make a little trick.

PHP

<?php

$ext_url = $_POST['ext_url'];

echo file_get_contents($ext_url);

?>

JS

$.ajax({
    method: 'POST',
    url: 'getContentFromUrl.php', // link to your PHP file
    data: {
        // url where our server will send request which can't be done by AJAX
        'ext_url': 'https://stackoverflow.com/questions/6114436/access-control-allow-origin-error-sending-a-jquery-post-to-google-apis'
    },
    success: function(data) {
        // we can find any data on external url, cause we've got all page
        var $h1 = $(data).find('h1').html();

        $('h1').val($h1);
    },
    error:function() {
        console.log('Error');
    }
});

How it works:

1. Your browser with the help of JS will send request to your server
2. Your server will send request to any other server and get reply from another server (any website)
3. Your server will send this reply to your JS

And we can make events onClick, put this event on some button. Hope this will help!

I suposse this is the output you need:

title,intro,tagline

2.9,Gardena,CA

It can be done with this changes to your code:

import csv
import itertools

with open('log.txt', 'r') as in_file:
    lines = in_file.read().splitlines()
    stripped = [line.replace(","," ").split() for line in lines]
    grouped = itertools.izip(*[stripped]*1)
    with open('log.csv', 'w') as out_file:
        writer = csv.writer(out_file)
        writer.writerow(('title', 'intro', 'tagline'))
        for group in grouped:
            writer.writerows(group)

After struggling with this issue too many times I found a very elegant solution in HTML 5. In HTML 5 you should not close several (li,p,etc) tags; the ambition to become XML is forever gone. For example, the preferred way to do a list is:

<ul>
   <li>
       <a ...>...</a>
   <li>
       <a ...>...</a>
</ul>

Browsers MUST close the LI and they must do this without introducing whitespace, solving this problem. If you still have the XML mindset it feels wrong but once you get over that it saves many a nightmare. And this is not a hack since it relies on the wording of the HTML 5 spec. Better, since not closing tags is pervasive I expect no compatibility issues (not tested though). Bonus is that HTML formatters handle this well.

A little worked out example: http://cssdesk.com/Ls7fK

See adeneo's answer, but to make this work in Excel in all countries you should add "SEP=," to the first line of the file. This will set the standard separator in Excel and will not show up in the actual document

var csvString = "SEP=, \n" + csvRows.join("\r\n");

A H4 elemental is a block display type element. You could force the H4 to have a inline display type, or simply use an inline element like P instead and style it however you require.

For reference: http://www.w3.org/TR/CSS21/visuren.html#propdef-display

So you'd change the display type of the H4 like:

<html>
<head>
   <title>test</title>
   <style type='text/css'>
     h4 { display: inline }
   </style>
  </head>
  <body>
  <img style='height: 24px; width: 24px; margin-right: 4px;' src='design/like.png'/><h4 class='liketext'>$likes</h4>
  <img style='height: 24px; width: 24px; margin-right: 4px;' src='design/dislike.png'/><h4 class='liketext'>$dislikes</h4>
</body>
</html>

It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:

When location matches the last part of the directive’s value: it is better to use the root directive instead:

which would yield:

server {
  listen        8080;
  server_name   www.mysite.com mysite.com;
  error_log     /home/www-data/logs/nginx_www.error.log;
  error_page    404    /404.html;

  location /public/doc/ {
    autoindex on;
    root  /home/www-data/mysite;
  } 

  location = /404.html {
    root /home/www-data/mysite/static/html;
  }       
}

Nested with statements will do the same job, and in my opinion, are more straightforward to deal with.

Let's say you have inFile.txt, and want to write it into two outFile's simultaneously.

with open("inFile.txt", 'r') as fr:
    with open("outFile1.txt", 'w') as fw1:
        with open("outFile2.txt", 'w') as fw2:
            for line in fr.readlines():
                fw1.writelines(line)
                fw2.writelines(line)

EDIT:

I don't understand the reason of the downvote. I tested my code before publishing my answer, and it works as desired: It writes to all of outFile's, just as the question asks. No duplicate writing or failing to write. So I am really curious to know why my answer is considered to be wrong, suboptimal or anything like that.

You can use both of these methods but there are differences:

SELECT ISNULL(col1, 0 ) FROM table1
SELECT COALESCE(col1, 0 ) FROM table1

Comparing COALESCE() and ISNULL():

1. The ISNULL function and the COALESCE expression have a similar purpose but can behave differently.

2. Because ISNULL is a function, it is evaluated only once. As described above, the input values for the COALESCE expression can be evaluated multiple times.

3. Data type determination of the resulting expression is different. ISNULL uses the data type of the first parameter, COALESCE follows the CASE expression rules and returns the data type of value with the highest precedence.

4. The NULLability of the result expression is different for ISNULL and COALESCE. The ISNULL return value is always considered NOT NULLable (assuming the return value is a non-nullable one) whereas COALESCE with non-null parameters is considered to be NULL. So the expressions ISNULL(NULL, 1) and COALESCE(NULL, 1) although equivalent have different nullability values. This makes a difference if you are using these expressions in computed columns, creating key constraints or making the return value of a scalar UDF deterministic so that it can be indexed as shown in the following example.

-- This statement fails because the PRIMARY KEY cannot accept NULL values -- and the nullability of the COALESCE expression for col2 -- evaluates to NULL.

CREATE TABLE #Demo 
( 
    col1 integer NULL, 
    col2 AS COALESCE(col1, 0) PRIMARY KEY, 
    col3 AS ISNULL(col1, 0) 
); 

-- This statement succeeds because the nullability of the -- ISNULL function evaluates AS NOT NULL.

CREATE TABLE #Demo 
( 
    col1 integer NULL, 
    col2 AS COALESCE(col1, 0), 
    col3 AS ISNULL(col1, 0) PRIMARY KEY 
);

5. Validations for ISNULL and COALESCE are also different. For example, a NULL value for ISNULL is converted to int whereas for COALESCE, you must provide a data type.

6. ISNULL takes only 2 parameters whereas COALESCE takes a variable number of parameters.

An answer from AlexGo did the trick for me:

getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
         messages.add(m);
         adapter.notifyDataSetChanged();
         getListView().setSelection(messages.size()-1);
        }
});

List Update worked for me before when the update was triggered from a GUI event, thus being in the UI thread.

However, when I update the list from another event/thread - i.e. a call from outside the app, the update would not be in the UI thread and it ignored the call to getListView. Calling the update with runOnUiThread as above did the trick for me. Thanks!!

I have changed min date property of date time picker by using this

Take a look at Blockspring - you do need to install the plugin, but then it's just another function you call like this:

=BLOCKSPRING("twodee-array-reduce","input_array",D5:F7)

The source code and other details are here. If this doesn't suit and/or you want to build off my solution, you can fork my function (Python) or use another supported scripting language (Ruby, R, JS, etc...).

You can plot the means without resorting to external calculations and additional tables using stat_summary(...). In fact, stat_summary(...) was designed for exactly what you are doing.

library(ggplot2)
library(reshape2)            # for melt(...)
gg <- melt(df,id="gender")   # df is your original table
ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) + 
  stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) + 
  scale_color_discrete("Gender")
  stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
               color="grey80",position=position_dodge(1), width=.2)

To add "error bars" you cna also use stat_summary(...) (here, I'm using the min and max value rather than sd because you have so little data).

ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) + 
  stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) + 
  stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
               color="grey40",position=position_dodge(1), width=.2) +
  scale_fill_discrete("Gender")

I've found what I think is an easier way. If you put an Iframe in the page, you can redirect the exit of the action there and make it show up. You can do nothing, of course. In that case, you can set the iframe display to none.

<iframe name="votar" style="display:none;"></iframe>
<form action="tip.php" method="post" target="votar">
    <input type="submit" value="Skicka Tips">
    <input type="hidden" name="ad_id" value="2">            
</form>

The inner join in your sub-query is unnecessary. It looks like you want to delete the entries in story_category where the category_id is not in the category table.

Do this:

DELETE FROM story_category 
WHERE category_id NOT IN (
    SELECT DISTINCT category.id 
    FROM category);

Instead of that:

DELETE FROM story_category 
WHERE category_id NOT IN (
    SELECT DISTINCT category.id 
    FROM category INNER JOIN
         story_category ON category_id=category.id);

Querydsl and jOOQ are two popular choices.

    var widthToHeight = 4 / 3;

    var newHeight = window.innerHeight;
    var newWidthToHeight = newWidth / newHeight;

    if (newWidthToHeight > widthToHeight) {
        newWidth = newHeight * widthToHeight;
        gameArea.style.height = newHeight + 'px';
        gameArea.style.width = newWidth + 'px';
    } else {
        newHeight = newWidth / widthToHeight;
        gameArea.style.width = newWidth + 'px';
        gameArea.style.height = newHeight + 'px';
    }

    gameArea.style.marginTop = (-newHeight / 2) + 'px';
    gameArea.style.marginLeft = (-newWidth / 2) + 'px';

    var gameCanvas = document.getElementById('gameCanvas');
    gameCanvas.width = newWidth;
    gameCanvas.height = newHeight;

    List_2.add("4");
    List_2.add("5");
    List_2.add("10");
    List_2.add("11");
    listOLists.add(List_2);
    for (int i = 0; i < listOLists.size(); i++) {
        System.out.print("list " + i + " :");
        for (int j = 0; j < listOLists.get(i).size(); j++) {
            System.out.print(listOLists.get(i).get(j) + " ;");
        }
        System.out.println();
    }

}

}

I hope this solution gives a better picture of list if lists

Another option, related to Kevin's, is use __FILE__, but instead replace the php file name from within it:

<?php

$docRoot = str_replace($_SERVER['SCRIPT_NAME'], '', __FILE__);
require_once($docRoot . '/lib/include.php');

?>

I've been using this for a while. The only problem is sometimes you don't have $_SERVER['SCRIPT_NAME'], but sometimes there is another variable similar.

The div doesn't take up all the available horizontal space when absolutely positioned. Explicitly setting the width to 100% will solve the problem:

HTML

<div id="my-div">I want to be centered</div>?

CSS

#my-div {
   position: absolute;
   bottom: 15px;
   text-align: center;
   width: 100%;
}

?

You can implement this way

$resource('http://localhost\\:3000/realmen/:entryId', {entryId: '@entryId'}, {
        UPDATE: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId' },
        ACTION: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId/action' }
    })

RealMen.query() //GET  /realmen/
RealMen.save({entryId: 1},{post data}) // POST /realmen/1
RealMen.delete({entryId: 1}) //DELETE /realmen/1

//any optional method
RealMen.UPDATE({entryId:1}, {post data}) // PUT /realmen/1

//query string
RealMen.query({name:'john'}) //GET /realmen?name=john

Hope it helps

It's really late now but I made a quick script which works for Windows, Mac and Linux, simply by using each command line:

import os, platform

def close():
    if platform.system() == "Windows":
        print("Press any key to exit . . .")
        os.system("pause>nul")
        exit()
    
    elif platform.system() == "Linux":
        os.system("read -n1 -r -p \"Press any key to exit . . .\" key")
        exit()
    
    elif platform.system() == "Darwin":
        print("Press any key to exit . . .")
        os.system("read -n 1 -s -p \"\"")
        exit()
    
    else:
        exit()

It uses only inbuilt functions, and should work for all three (although I've only tested Windows and Linux...).

add this code in .htaccess (as an alternative of php.ini / ini_set function):

<IfModule mod_php5.c>
php_flag log_errors on 
php_value error_log ./path_to_MY_PHP_ERRORS.log
# php_flag display_errors on 
</IfModule>

* as commented: this is for Apache-type servers, and not for Nginx or others.

I know this was answered a while ago but just chiming with a simple solution here that I am surprised wasn't mentioned.

=RIGHT("0000" & A1, 4)

Whenever I need to pad I use something like the above. Personally I find it the simplest solution and easier to read.

Rather than relying on errors, you can query INFORMATION_SCHEMA.TABLES to see if the table exists. If there's a record, it exists. If there's no record, it doesn't exist.

Outdated answer. Please use dplyr::sample_frac() or dplyr::sample_n() instead.

In my R package there is a function sample.rows just for this purpose:

install.packages('kimisc')

library(kimisc)
example(sample.rows)

smpl..> set.seed(42)

smpl..> sample.rows(data.frame(a=c(1,2,3), b=c(4,5,6),
                               row.names=c('a', 'b', 'c')), 10, replace=TRUE)
    a b
c   3 6
c.1 3 6
a   1 4
c.2 3 6
b   2 5
b.1 2 5
c.3 3 6
a.1 1 4
b.2 2 5
c.4 3 6

Enhancing sample by making it a generic S3 function was a bad idea, according to comments by Joris Meys to a previous answer.
