Encoding and decoding can solve this in Python 3:

Client Side:

>>> host='127.0.0.1'
>>> port=1337
>>> import socket
>>> s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
>>> s.connect((host,port))
>>> st='connection done'
>>> byt=st.encode()
>>> s.send(byt)
15
>>>

Server Side:

>>> host=''
>>> port=1337
>>> import socket
>>> s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
>>> s.bind((host,port))
>>> s.listen(1)
>>> conn ,addr=s.accept()
>>> data=conn.recv(2000)
>>> data.decode()
'connection done'
>>>

I'll try to keep this short, I've done this a few months ago for a game I was trying to build, it does a UDP "Client-Server" connection that acts like TCP, you can send (message) (message + object) using this. I've done some testing with it and it works just fine, feel free to modify it if needed.

This worked for me both in gmail and outlook.

I think a lot of people concentrate on the fact that this value is nullable, and don't think about what they actually want :)

bool? nullableBool = true;
if (nullableBool == true) { ... } // true
else { ... } // false or null

Or if you want more options...

bool? nullableBool = true;
if (nullableBool == true) { ... } // true
else if (nullableBool == false) { ... } // false
else { ... } // null

(nullableBool == true) will never return true if the bool? is null :P

Another reason why many prefer hyphens in CSS id and class names is functionality.

Using keyboard shortcuts like option + left/right (or ctrl+left/right on Windows) to traverse code word by word stops the cursor at each dash, allowing you to precisely traverse the id or class name using keyboard shortcuts. Underscores and camelCase do not get detected and the cursor will drift right over them as if it were all one single word.

With a wider view of what you're actually trying to do and the context in which you're doing it, I'm sure we could give you a better answer than the literal answer to your question.

But here's a literal answer:

If you're assigning these functions to some property somewhere, you can wrap the original function and put your replacement on the property instead:

// Original code in main.js
var theProperty = init;

function init(){
     doSomething();
}

// Extending it by replacing and wrapping, in extended.js
theProperty = (function(old) {
    function extendsInit() {
        old();
        doSomething();
    }

    return extendsInit;
})(theProperty);

If your functions aren't already on an object, you'd probably want to put them there to facilitate the above. For instance:

// In main.js
var MyLibrary = {
    init: function init() {
    }
};

// In extended.js
(function() {
    var oldInit = MyLibrary.init;
    MyLibrary.init = extendedInit;
    function extendedInit() {
        oldInit.call(MyLibrary); // Use #call in case `init` uses `this`
        doSomething();
    }
})();

But there are better ways to do that. Like for instance, providing a means of registering init functions.

// In main.js
var MyLibrary = (function() {
    var initFunctions = [];
    return {
        init: function init() {
            var fns = initFunctions;
            initFunctions = undefined;
            for (var index = 0; index < fns.length; ++index) {
                try { fns[index](); } catch (e) { }
            }
        },
        addInitFunction: function addInitFunction(fn) {
            if (initFunctions) {
                // Init hasn't run yet, remember it
                initFunctions.push(fn);
            } else {
                // `init` has already run, call it almost immediately
                // but *asynchronously* (so the caller never sees the
                // call synchronously)
                setTimeout(fn, 0);
            }
        }
    };
})();

Here in 2020 (or really any time after ~2016), that can be written a bit more compactly:

// In main.js
const MyLibrary = (() => {
    let initFunctions = [];
    return {
        init() {
            const fns = initFunctions;
            initFunctions = undefined;
            for (const fn of fns) {
                try { fn(); } catch (e) { }
            }
        },
        addInitFunction(fn) {
            if (initFunctions) {
                // Init hasn't run yet, remember it
                initFunctions.push(fn);
            } else {
                // `init` has already run, call it almost immediately
                // but *asynchronously* (so the caller never sees the
                // call synchronously)
                setTimeout(fn, 0);
                // Or: `Promise.resolve().then(() => fn());`
                // (Not `.then(fn)` just to avoid passing it an argument)
            }
        }
    };
})();

It's not a matter of security. The HTTP protocol defines GET-type requests as being idempotent, while POSTs may have side effects. In plain English, that means that GET is used for viewing something, without changing it, while POST is used for changing something. For example, a search page should use GET, while a form that changes your password should use POST.

Also, note that PHP confuses the concepts a bit. A POST request gets input from the query string and through the request body. A GET request just gets input from the query string. So a POST request is a superset of a GET request; you can use $_GET in a POST request, and it may even make sense to have parameters with the same name in $_POST and $_GET that mean different things.

For example, let's say you have a form for editing an article. The article-id may be in the query string (and, so, available through $_GET['id']), but let's say that you want to change the article-id. The new id may then be present in the request body ($_POST['id']). OK, perhaps that's not the best example, but I hope it illustrates the difference between the two.

You could call this method

+(id)stringWithUTF8String:(const char *)bytes.

Short version: it's marking that hash as attached to the current package namespace (so that that package provides its class implementation).

I am copy pasting from the Jupyter/IPython Notebook Quick Start Guide Documentation, released on Feb 13, 2018. http://jupyter-notebook-beginner-guide.readthedocs.io/en/latest/execute.html

1.3.3 Close a notebook: kernel shut down When a notebook is opened, its “computational engine” (called the kernel) is automatically started. Closing the notebook browser tab, will not shut down the kernel, instead the kernel will keep running until is explicitly shut down. To shut down a kernel, go to the associated notebook and click on menu File -> Close and Halt. Alternatively, the Notebook Dashboard has a tab named Running that shows all the running notebooks (i.e. kernels) and allows shutting them down (by clicking on a Shutdown button).

Summary: First close and halt the notebooks running.

1.3.2 Shut down the Jupyter Notebook App Closing the browser (or the tab) will not close the Jupyter Notebook App. To completely shut it down you need to close the associated terminal. In more detail, the Jupyter Notebook App is a server that appears in your browser at a default address (http://localhost:8888). Closing the browser will not shut down the server. You can reopen the previous address and the Jupyter Notebook App will be redisplayed. You can run many copies of the Jupyter Notebook App and they will show up at a similar address (only the number after “:”, which is the port, will increment for each new copy). Since with a single Jupyter Notebook App you can already open many notebooks, we do not recommend running multiple copies of Jupyter Notebook App.

Summary: Second, quit the terminal from which you fired Jupyter.

MemoryStream ms = new MemoryStream();
yourBitmap.Save(ms, ImageFormat.Bmp);
byte[] bitmapData = ms.ToArray();

You can try the code here:

http://htmledit.squarefree.com/

The code below will convert any XMLObject or string to a native JavaScript object. Then you can walk on the object to extract any value you want.

/**
 * Tries to convert a given XML data to a native JavaScript object by traversing the DOM tree.
 * If a string is given, it first tries to create an XMLDomElement from the given string.
 * 
 * @param {XMLDomElement|String} source The XML string or the XMLDomElement prefreably which containts the necessary data for the object.
 * @param {Boolean} [includeRoot] Whether the "required" main container node should be a part of the resultant object or not.
 * @return {Object} The native JavaScript object which is contructed from the given XML data or false if any error occured.
 */
Object.fromXML = function( source, includeRoot ) {
    if( typeof source == 'string' )
    {
        try
        {
            if ( window.DOMParser )
                source = ( new DOMParser() ).parseFromString( source, "application/xml" );
            else if( window.ActiveXObject )
            {
                var xmlObject = new ActiveXObject( "Microsoft.XMLDOM" );
                xmlObject.async = false;
                xmlObject.loadXML( source );
                source = xmlObject;
                xmlObject = undefined;
            }
            else
                throw new Error( "Cannot find an XML parser!" );
        }
        catch( error )
        {
            return false;
        }
    }

    var result = {};

    if( source.nodeType == 9 )
        source = source.firstChild;
    if( !includeRoot )
        source = source.firstChild;

    while( source ) {
        if( source.childNodes.length ) {
            if( source.tagName in result ) {
                if( result[source.tagName].constructor != Array ) 
                    result[source.tagName] = [result[source.tagName]];
                result[source.tagName].push( Object.fromXML( source ) );
            }
            else 
                result[source.tagName] = Object.fromXML( source );
        } else if( source.tagName )
            result[source.tagName] = source.nodeValue;
        else if( !source.nextSibling ) {
            if( source.nodeValue.clean() != "" ) {
                result = source.nodeValue.clean();
            }
        }
        source = source.nextSibling;
    }
    return result;
};

String.prototype.clean = function() {
    var self = this;
    return this.replace(/(\r\n|\n|\r)/gm, "").replace(/^\s+|\s+$/g, "");
}

Putting the code in a function, then using a decorator for timing is another option. (Source) The advantage of this method is that you define timer once and use it with a simple additional line for every function.

First, define timer decorator:

import functools
import time

def timer(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        start_time = time.perf_counter()
        value = func(*args, **kwargs)
        end_time = time.perf_counter()
        run_time = end_time - start_time
        print("Finished {} in {} secs".format(repr(func.__name__), round(run_time, 3)))
        return value

    return wrapper

Then, use the decorator while defining the function:

@timer
def doubled_and_add(num):
    res = sum([i*2 for i in range(num)])
    print("Result : {}".format(res))

Let's try:

doubled_and_add(100000)
doubled_and_add(1000000)

Output:

Result : 9999900000
Finished 'doubled_and_add' in 0.0119 secs
Result : 999999000000
Finished 'doubled_and_add' in 0.0897 secs

Note: I'm not sure why to use time.perf_counter instead of time.time. Comments are welcome.

In my case, the site was fine in server but not in local. Then I remember I was working on secure website.
So in file config.session.php, set the variable secure to false

'secure' => env('SESSION_SECURE_COOKIE', false),

If you already know that the path separator is / (i.e. you are writing for a specific platform/environment), as implied by the example in your question, you could keep it simple and split the string by separator:

'/foo/bar/baz/asdf/quux.html'.split('/').pop()

That would be faster (and cleaner imo) than replacing by regular expression.

Again: Only do this if you're writing for a specific environment, otherwise use the path module, as paths are surprisingly complex. Windows, for instance, supports / in many cases but not for e.g. the \\?\? style prefixes used for shared network folders and the like. On Windows the above method is doomed to fail, sooner or later.

Master project

Here is the package.json you will use for the master project:

"dependencies": {
    "express": "*",
    "somelocallib": "file:./somelocallib"
}

There, ./somelocallib is the reference to the library folder as relative to the master project package.json.

Reference: https://docs.npmjs.com/files/package.json#local-paths

Sub project

Handle your library dependencies.

In addition to running npm install, you will need to run (cd node_modules/somelocallib && npm install).

This is a known bug with NPM.

Reference: https://github.com/npm/npm/issues/1341 (seeking a more up-to-date reference)

Notes for Docker

Check in your master package.lock and your somelocallib/package.lock into your source code manager.

Then in your Dockerfile use:

FROM node:10
WORKDIR /app
# ...
COPY ./package.json ./package-lock.json ./
COPY somelocallib somelocallib
RUN npm ci
RUN (cd node_modules/zkp-utils/ && npm ci)
# ...

I use parenthesis in my (cd A && B) constructs to make the operation idempotent.

Using emplace_back function is way better than any other method since it creates an object in-place of type T where vector<T>, whereas push_back expects an actual value from you.

vector<pair<string,double>> revenue;

// make_pair function constructs a pair objects which is expected by push_back
revenue.push_back(make_pair("cash", 12.32));

// emplace_back passes the arguments to the constructor
// function and gets the constructed object to the referenced space
revenue.emplace_back("cash", 12.32);

Very old post, but since it helped me after I made some modifications, I thought I'd share. If you're checking to see if a directory exists, you'll want to add the vbDirectory argument to the Dir function, otherwise you'll return 0 each time. (Edit: this was in response to Roy's answer, but I accidentally made it a regular answer.)

Private Function FileExists(fullFileName As String) As Boolean
    FileExists = Len(Dir(fullFileName, vbDirectory)) > 0
End Function

I probably prefer to invoke the ToTitleCase from CultureInfo (System.Globalization) than Thread.CurrentThread (System.Threading)

string s = "THIS IS MY TEXT RIGHT NOW";
s = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());

but it should be the same as jspcal solution

EDIT

Actually those solutions are not the same: CurrentThread --calls--> CultureInfo!

System.Threading.Thread.CurrentThread.CurrentCulture

string s = "THIS IS MY TEXT RIGHT NOW";
s = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());

IL_0000:  ldstr       "THIS IS MY TEXT RIGHT NOW"
IL_0005:  stloc.0     // s
IL_0006:  call        System.Threading.Thread.get_CurrentThread
IL_000B:  callvirt    System.Threading.Thread.get_CurrentCulture
IL_0010:  callvirt    System.Globalization.CultureInfo.get_TextInfo
IL_0015:  ldloc.0     // s
IL_0016:  callvirt    System.String.ToLower
IL_001B:  callvirt    System.Globalization.TextInfo.ToTitleCase
IL_0020:  stloc.0     // s

System.Globalization.CultureInfo.CurrentCulture

string s = "THIS IS MY TEXT RIGHT NOW";
s = System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());

IL_0000:  ldstr       "THIS IS MY TEXT RIGHT NOW"
IL_0005:  stloc.0     // s
IL_0006:  call        System.Globalization.CultureInfo.get_CurrentCulture
IL_000B:  callvirt    System.Globalization.CultureInfo.get_TextInfo
IL_0010:  ldloc.0     // s
IL_0011:  callvirt    System.String.ToLower
IL_0016:  callvirt    System.Globalization.TextInfo.ToTitleCase
IL_001B:  stloc.0     // s

If the link should only change the location if the function run is successful, then do onclick="return runMyFunction();" and in the function you would return true or false.

If you just want to run the function, and then let the anchor tag do its job, simply remove the return false statement.

As a side note, you should probably use an event handler instead, as inline JS isn't a very optimal way of doing things.

public function rules()
{
    if ($this->method() == 'PUT') {
        $post_id = $this->segment(3);
        $rules = [
            'post_title' => 'required|unique:posts,post_title,' . $post_id
        ];
    } else {
        $rules = [
            'post_title' => 'required|unique:posts,post_title'
        ];
    }
    return $rules;
}

If you still have problems with UIScrollView, just turn off Content Layout Guides (Select your ScrollView in xcode Interface Builder -> choose Size inspector in right panel -> deselect 'Content Layout Guides') Or try these steps: xcode 11 scroll view layouts - it can be useful for new style of layout. Works fine at macOS 10.15.2, Xcode 11.3.1, for 05.02.2020

Replace measureScrapChild to follow code:

private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
        int heightSpec, int[] measuredDimension)
    {
        View view = recycler.GetViewForPosition(position);
        if (view != null)
        {
            MeasureChildWithMargins(view, widthSpec, heightSpec);
            measuredDimension[0] = view.MeasuredWidth;
            measuredDimension[1] = view.MeasuredHeight;
            recycler.RecycleView(view);
        }
    }

I use xamarin, so this is c# code. I think this can be easily "translated" to Java.

One basic way that comes to mind would be to put the item into a table and have two cells, one with the text, the other with the image, and use style="valign:center" with the tags.

Try this:

apt-get install lib32stdc++6

Alternatively, If you are using Apache then you can use .htaccess file to enforce your URLs to use https prefix. On Laravel 5.4, I added the following lines to my .htaccess file and it worked for me.

RewriteEngine On

RewriteCond %{HTTPS} !on
RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

You can write like

UILabel *reviews = [[UILabel alloc]initWithFrame:CGRectMake(14, 13,270,30)];//Set frame
reviews.numberOfLines=0;
reviews.textAlignment = UITextAlignmentLeft;
reviews.font = [UIFont fontWithName:@"Arial Rounded MT Bold" size:12];
reviews.textColor=[UIColor colorWithRed:0.0/255.0 green:0.0/255.0 blue:0.0/255.0 alpha:0.8]; 
reviews.backgroundColor=[UIColor clearColor];

You can calculate number of lines like that

CGSize maxlblSize = CGSizeMake(270,9999);
CGSize totalSize = [reviews.text sizeWithFont:reviews.font 
              constrainedToSize:maxlblSize lineBreakMode:reviews.lineBreakMode];

CGRect newFrame =reviews.frame;
newFrame.size.height = totalSize.height;
reviews.frame = newFrame;

CGFloat reviewlblheight = totalSize.height;

int lines=reviewlblheight/12;//12 is the font size of label

UILabel *lbl=[[UILabel alloc]init];
lbl.frame=CGRectMake(140,220 , 100, 25);//set frame as your requirement
lbl.font=[UIFont fontWithName:@"Arial" size:20];
[lbl setAutoresizingMask:UIViewContentModeScaleAspectFill];
[lbl setLineBreakMode:UILineBreakModeClip];
lbl.adjustsFontSizeToFitWidth=YES;//This is main for shrinking font
lbl.text=@"HelloHelloHello";

For my answer, it is worth remembering that the TPL (Task-Parallel-Library), Task class and TaskStatus enumeration were introduced prior to the async-await keywords and the async-await keywords were not the original motivation of the TPL.

In the context of methods marked as async, the resulting Task is not a Task representing the execution of the method, but a Task for the continuation of the method.

This is only able to make use of a few possible states:

• Canceled
• Faulted
• RanToCompletion
• WaitingForActivation

I understand that Runningcould appear to have been a better default than WaitingForActivation, however this could be misleading, as the majority of the time, an async method being executed is not actually running (i.e. it may be await-ing something else). The other option may have been to add a new value to TaskStatus, however this could have been a breaking change for existing applications and libraries.

All of this is very different to when making use of Task.Run which is a part of the original TPL, this is able to make use of all the possible values of the TaskStatus enumeration.

If you wish to keep track of the status of an async method, take a look at the IProgress(T) interface, this will allow you to report the ongoing progress. This blog post, Async in 4.5: Enabling Progress and Cancellation in Async APIs will provide further information on the use of the IProgress(T) interface.

OFFICE 2013 INSTRUCTIONS:

(For Windows 7 (x64) | MS Office 32-Bit)

Option 1 | Check if ability already exists | 2 minutes

1. Open VB Editor
2. Tools -> Additional Controls
3. Select "Microsoft Monthview Control 6.0 (SP6)" (if applicable)
4. Use 'DatePicker' control for VBA Userform

Option 2 | The "Monthview" Control doesn't currently exist | 5 minutes

1. Close Excel
2. Download MSCOMCT2.cab (it's a cabinet file which extracts into two useful files)
3. Extract Both Files | the .inf file and the .ocx file
4. Install | right-click the .inf file | hit "Install"
5. Move .ocx file | Move from "C:\Windows\system32" to "C:\Windows\sysWOW64"
6. Run CMD | Start Menu -> Search -> "CMD.exe" | right-click the icon | Select "Run as administrator"
7. Register Active-X File | Type "regsvr32 c:\windows\sysWOW64\MSCOMCT2.ocx"
8. Open Excel | Open VB Editor
9. Activate Control | Tools->References | Select "Microsoft Windows Common Controls 2-6.0 (SP6)"
10. Userform Controls | Select any userform in VB project | Tools->Additional Controls
11. Select "Microsoft Monthview Control 6.0 (SP6)"
12. Use 'DatePicker' control for VBA UserForm

Okay, either of these two steps should work for you if you have Office 2013 (32-Bit) on Windows 7 (x64). Some of the steps may be different if you have a different combo of Windows 7 & Office 2013.

The "Monthview" control will be your fully fleshed out 'DatePicker'. It comes equipped with its own properties and image. It works very well. Good luck.

I think you can also use match():

largetable$HouseTypeNo <- with(lookup,
                     HouseTypeNo[match(largetable$HouseType,
                                       HouseType)])

This still works if I scramble the order of lookup.

i geted through the same problem. I my case the table already have data and there were key in this table that was not present in the reference table. So i had to delete this rows that disrespect the constraints and everything worked.

@media screen and (max-width: 767px) {

}

@media screen and (min-width: 768px) and (max-width: 991px){


}

@media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : landscape){


}

@media screen and (min-width: 992px) {



}

I created a JsFiddle here based on the answer given by Zachary. It provides a more accessible user interface and also escapes double quotes within strings properly.

You can just use either of the following approaches:

.center-block {
  margin: auto;
  display: block;
}

<div>
  <input class="center-block">
</div>

.parent {
  display: grid;
  place-items: center;
}

<div class="parent">
  <input>

This worked for me.

look for this:

    DirectoryIndex index.php

replace with this:

    DirectoryIndex something.php index.php

Upload and refresh page. You will get a page error.

just change it back to:

    DirectoryIndex index.php

reupload and refresh page again.
I checked this on all of my devices and, it worked.

For my circumstance, I'm using sdkman to manage multiple java versions. I set default java version to 13. Install version 8 and now it's working fine.

Maybe you can use a for loop that goes through the String content and extract characters by characters using the charAt method.

Combined with an ArrayList<String> for example you can get your array of individual characters.

I feel like the answer provided by static_rtti is hacky in some sense. I don't know if this was available earlier, but Git tools now provide credential storage.

Cache Mode

$ git config --global credential.helper cache

Use the “cache” mode to keep credentials in memory for a certain period of time. None of the passwords are ever stored on disk, and they are purged from the cache after 15 minutes.

Store Mode

$ git config --global credential.helper 'store --file ~/.my-credentials'

Use the “store” mode to save the credentials to a plain-text file on disk, and they never expire.

I personally used the store mode. I deleted my repository, cloned it, and then had to enter my credentials once.

If you don't want to use pip-autoremove (since it removes dependencies shared among other packages) and pip3 uninstall jupyter just removed some packages, then do the following:

Copy-Paste:

sudo may be needed as per your need.

python3 -m pip uninstall -y jupyter jupyter_core jupyter-client jupyter-console jupyterlab_pygments notebook qtconsole nbconvert nbformat

Note:

The above command will only uninstall jupyter specific packages. I have not added other packages to uninstall since they might be shared among other packages (eg: Jinja2 is used by Flask, ipython is a separate set of packages themselves, tornado again might be used by others).

In any case, all the dependencies are mentioned below(as of 21 Nov, 2020. jupyter==4.4.0 )

If you are sure you want to remove all the dependencies, then you can use Stan_MD's answer.

It's depends on if your computer support WMI. My computer can't run this WMI demo too.

But I successfully get the CPU temperature via Open Hardware Monitor. Add the Openhardwaremonitor reference in Visual Studio. It's easier. Try this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenHardwareMonitor.Hardware;
namespace Get_CPU_Temp5
{
   class Program
   {
       public class UpdateVisitor : IVisitor
       {
           public void VisitComputer(IComputer computer)
           {
               computer.Traverse(this);
           }
           public void VisitHardware(IHardware hardware)
           {
               hardware.Update();
               foreach (IHardware subHardware in hardware.SubHardware) subHardware.Accept(this);
           }
           public void VisitSensor(ISensor sensor) { }
           public void VisitParameter(IParameter parameter) { }
       }
       static void GetSystemInfo()
       {
           UpdateVisitor updateVisitor = new UpdateVisitor();
           Computer computer = new Computer();
           computer.Open();
           computer.CPUEnabled = true;
           computer.Accept(updateVisitor);
           for (int i = 0; i < computer.Hardware.Length; i++)
           {
               if (computer.Hardware[i].HardwareType == HardwareType.CPU)
               {
                   for (int j = 0; j < computer.Hardware[i].Sensors.Length; j++)
                   {
                       if (computer.Hardware[i].Sensors[j].SensorType == SensorType.Temperature)
                               Console.WriteLine(computer.Hardware[i].Sensors[j].Name + ":" + computer.Hardware[i].Sensors[j].Value.ToString() + "\r");
                   }
               }
           }
           computer.Close();

           {
               GetSystemInfo();
           }
       }
   }
}

You need to run this demo as administrator.

In my case Drag & Drop didn't work.

1. I had to first Sync iTunes with the iOS device (Sync button on the bottom right)
2. I had to add the IPA file through iTunes menu bar: File -> Add to Library...
3. I had to press the "Install" button for my app in the "Apps" screen
4. I had to press the "Apply" button on the bottom right

DriveInfo will help you with some of those (but it doesn't work with UNC paths), but really I think you will need to use GetDiskFreeSpaceEx. You can probably achieve some functionality with WMI. GetDiskFreeSpaceEx looks like your best bet.

Chances are you will probably have to clean up your paths to get it to work properly.

First of all load URL helper. you can load in "config/autoload.php" file and add following code $autoload['helper'] = array('url');

or in controller add following code

$this->load->helper('url');

then go to config.php in cofig folder and set

$config['base_url'] = 'http://urlbaseurl.com/';

hope this will help thanks

None of the answers provided here are completely correct when using TypeScript, as you may not know the kind of element that is selected.

This would therefore be preferred:

if (document.activeElement instanceof HTMLElement)
    document.activeElement.blur();

I would furthermore discourage using the solution provided in the accepted answer, as the resulting blurring is not part of the official spec, and could break at any moment.

For me it was occurring in a .net project and turned out to be something to do with my Visual Studio installation. I downloaded and installed the latest .net core sdk separately and then reinstalled VS and it worked.

What you're looking for is called a "reverse merge". You should consult the docs regarding the merge function in the SVN book (as luapyad, or more precisely the first commenter on that post, points out). If you're using Tortoise, you can also just go into the log view and right-click and choose "revert changes from this revision" on the one where you made the mistake.

this could help you..:D

My guess is that byteArrayIn doesn't contain valid image data.

Please give more information though:

• Which line of code is throwing an exception?
• What's the message?
• Where did you get byteArrayIn from, and are you sure it should contain a valid image?

Already mentioned apache commons-utils:

org.apache.commons.lang.time.DateUtils.truncate(date, Calendar.DAY_OF_MONTH)

gives you Date object containing only date, without time, and you can compare it with Date.compareTo

Require the JSON library, and use to_json.

require 'json'
tempHash = {
    "key_a" => "val_a",
    "key_b" => "val_b"
}
File.open("public/temp.json","w") do |f|
  f.write(tempHash.to_json)
end

Your temp.json file now looks like:

{"key_a":"val_a","key_b":"val_b"}

Having problems connecting to SQL Server?

Try disconnecting firewall.

If you can connect with firewall disconnected, may be you miss some input rules like "sql service broker", add this input rules to your firewall:

"SQL ADMIN CONNECTION" TCP PORT 1434

"SQL ADMIN CONNECTION" UDP PORT 1434

"SQL ANALYSIS SERVICE" TCP PORT 2383

"SQL BROWSE ANALYSIS SERVICE" TCP PORT 2382

"SQL DEBUGGER/RPC" TCP PORT 135

"SQL SERVER" TCP PORT 1433 and others if you have dinamic ports

"SQL SERVICE BROKER" TCP PORT 4022

There is no way to do it in JavaScript natively. (See Riccardo Galli's answer for a modern approach.)

For historical reference or where TextEncoder APIs are still unavailable.

If you know the character encoding, you can calculate it yourself though.

encodeURIComponent assumes UTF-8 as the character encoding, so if you need that encoding, you can do,

function lengthInUtf8Bytes(str) {
  // Matches only the 10.. bytes that are non-initial characters in a multi-byte sequence.
  var m = encodeURIComponent(str).match(/%[89ABab]/g);
  return str.length + (m ? m.length : 0);
}

This should work because of the way UTF-8 encodes multi-byte sequences. The first encoded byte always starts with either a high bit of zero for a single byte sequence, or a byte whose first hex digit is C, D, E, or F. The second and subsequent bytes are the ones whose first two bits are 10. Those are the extra bytes you want to count in UTF-8.

The table in wikipedia makes it clearer

Bits        Last code point Byte 1          Byte 2          Byte 3
  7         U+007F          0xxxxxxx
 11         U+07FF          110xxxxx        10xxxxxx
 16         U+FFFF          1110xxxx        10xxxxxx        10xxxxxx
...

If instead you need to understand the page encoding, you can use this trick:

function lengthInPageEncoding(s) {
  var a = document.createElement('A');
  a.href = '#' + s;
  var sEncoded = a.href;
  sEncoded = sEncoded.substring(sEncoded.indexOf('#') + 1);
  var m = sEncoded.match(/%[0-9a-f]{2}/g);
  return sEncoded.length - (m ? m.length * 2 : 0);
}

1. checked
2. checked=""

3. checked="checked"

   are equivalent;

according to spec checkbox '----? checked = "checked" or "" (empty string) or empty Specifies that the element represents a selected control.---'

Edit /etc/yum.repos.d/Centos* so that all lines that have enabled = 0 instead have enabled = 1.

Here is a little research that explored RDBMS vs NoSQL using MySQL vs Mongo, the conclusions were inline with @Sean Reilly's response. In short, the benefit comes from the design, not some raw speed difference. Conclusion on page 35-36:

RDBMS vs NoSQL: Performance and Scaling Comparison

The project tested, analysed and compared the performance and scalability of the two database types. The experiments done included running different numbers and types of queries, some more complex than others, in order to analyse how the databases scaled with increased load. The most important factor in this case was the query type used as MongoDB could handle more complex queries faster due mainly to its simpler schema at the sacrifice of data duplication meaning that a NoSQL database may contain large amounts of data duplicates. Although a schema directly migrated from the RDBMS could be used this would eliminate the advantage of MongoDB’s underlying data representation of subdocuments which allowed the use of less queries towards the database as tables were combined. Despite the performance gain which MongoDB had over MySQL in these complex queries, when the benchmark modelled the MySQL query similarly to the MongoDB complex query by using nested SELECTs MySQL performed best although at higher numbers of connections the two behaved similarly. The last type of query benchmarked which was the complex query containing two JOINS and and a subquery showed the advantage MongoDB has over MySQL due to its use of subdocuments. This advantage comes at the cost of data duplication which causes an increase in the database size. If such queries are typical in an application then it is important to consider NoSQL databases as alternatives while taking in account the cost in storage and memory size resulting from the larger database size.

From API level 17 and above, you can call: View.generateViewId()

Then use View.setId(int).

If your app is targeted lower than API level 17, use ViewCompat.generateViewId()

If you are looking to highlight a shell session command sequence as it looks to the user (with prompts, not just as contents of a hypothetical script file), then the right identifier to use at the moment is console:

```console
foo@bar:~$ whoami
foo
```

Convert JavaScript object to json data

$("form").submit(function(event){
  event.preventDefault();
  var formData = $("form").serializeArray(); // Create array of object
  var jsonConvertedData = JSON.stringify(formData);  // Convert to json
  consol.log(jsonConvertedData);
});

You can validate json data using http://jsonlint.com

Not sure why this has not been mentioned, yet:

{% load l10n %}

{{ value|localize }}

https://docs.djangoproject.com/en/1.11/topics/i18n/formatting/#std:templatefilter-localize

You can also use this in your Django code (outside templates) by calling localize(number).

I know this is an old thread, but because people can still look this up and rely on it, it seems important to point out that lock(typeof(SomeObject)) is significantly worse than lock(this). Having said that; sincere kudos to Alan for pointing out that lock(typeof(SomeObject)) is bad practice.

An instance of System.Type is one of the most generic, coarse-grained objects there is. At the very least, an instance of System.Type is global to an AppDomain, and .NET can run multiple programs in an AppDomain. This means that two entirely different programs could potentially cause interference in one another even to the extent of creating a deadlock if they both try to get a synchronization lock on the same type instance.

So lock(this) isn't particularly robust form, can cause problems and should always raise eyebrows for all the reasons cited. Yet there is widely used, relatively well-respected and apparently stable code like log4net that uses the lock(this) pattern extensively, even though I would personally prefer to see that pattern change.

But lock(typeof(SomeObject)) opens up a whole new and enhanced can of worms.

For what it's worth.

Yes you can very easily downloads Files from the remote Url Using this code. This Code is working Fine for Me.

func DownlondFromUrl(){
   // Create destination URL 
let documentsUrl:URL =  FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
let destinationFileUrl = documentsUrl.appendingPathComponent("downloadedFile.jpg")

//Create URL to the source file you want to download
let fileURL = URL(string: "https://s3.amazonaws.com/learn-swift/IMG_0001.JPG")

let sessionConfig = URLSessionConfiguration.default
let session = URLSession(configuration: sessionConfig)

let request = URLRequest(url:fileURL!)

let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
    if let tempLocalUrl = tempLocalUrl, error == nil {
        // Success
        if let statusCode = (response as? HTTPURLResponse)?.statusCode {
            print("Successfully downloaded. Status code: \(statusCode)")
        }

        do {
            try FileManager.default.copyItem(at: tempLocalUrl, to: destinationFileUrl)
        } catch (let writeError) {
            print("Error creating a file \(destinationFileUrl) : \(writeError)")
        }

    } else {
        print("Error took place while downloading a file. Error description: %@", error?.localizedDescription);
    }
}
task.resume()
}

In addition to the suggestions given, you can do this directly from your query like this -

SELECT ISNULL([Additional], -1) AS [Additional]

This way you can write the condition to check whether the field value is < 0 or >= 0.

echo "echo "we are now going to work with ${ser}" " >> $servfile

Escape all " within quotes with \. Do this with variables like \$servicetest too:

echo "echo \"we are now going to work with \${ser}\" " >> $servfile    
echo "read -p \"Please enter a service: \" ser " >> $servfile
echo "if [ \$servicetest > /dev/null ];then " >> $servfile

I'm not sure you can label obfuscation of an interpreted language as pointless (I'm unable to add a comment to Schwern's post, so here goes a new entry).

I think it's a little shortsighted to assume you know all the possible scenarios where someone would like to obfuscate code, and you assume that anyone will actually be willing to go to whatever necessary lengths to view that code once obfuscated. Consider my current scenario:

I work for a consulting company that is developing a large and fairly sophisticated PHP-based site. The project will be hosted on a client's server that is hosting other sites developed by other consultancies. Technically any code we write is owned by the client, so we can't license it. However, any other consultancy (competitor) with access to the server can copy our code without getting permission from the client first. We therefore have a genuine reason for obfuscation - to make the effort required for a competitor to understand our code more than the effort of creating a copy of our work from scratch.

These helped me a lot: I wanted to save values from my gridview, and it was reloading my gridview /overriding my new values, as i have IsPostBack inside my PageLoad.

if (HttpContext.Current.Request["MYCLICKEDBUTTONID"] == null)
{
   //Do not reload the gridview.

}
else
{
   reload my gridview.
}

    private static readonly ICollection<string> PositiveList = new Collection<string> { "Y", "Yes", "T", "True", "1", "OK" };

public static bool ToBoolean(this string input)
{
                return input != null && PositiveList.Any(? => ?.Equals(input, StringComparison.OrdinalIgnoreCase));
}

You can stub a static void method like this:

PowerMockito.doNothing().when(StaticResource.class, "getResource", anyString());

Although I'm not sure why you would bother, because when you call mockStatic(StaticResource.class) all static methods in StaticResource are by default stubbed

More useful, you can capture the value passed to StaticResource.getResource() like this:

ArgumentCaptor<String> captor = ArgumentCaptor.forClass(String.class);
PowerMockito.doNothing().when(
               StaticResource.class, "getResource", captor.capture());

Then you can evaluate the String that was passed to StaticResource.getResource like this:

String resourceName = captor.getValue();

Try this function. I just wrote it and haven't had much of a chance to test it, but my preliminary tests are promising.

public static XmlDocument JsonToXml(string json)
{
    XmlNode newNode = null;
    XmlNode appendToNode = null;
    XmlDocument returnXmlDoc = new XmlDocument();
    returnXmlDoc.LoadXml("<Document />");
    XmlNode rootNode = returnXmlDoc.SelectSingleNode("Document");
    appendToNode = rootNode;

    string[] arrElementData;
    string[] arrElements = json.Split('\r');
    foreach (string element in arrElements)
    {
        string processElement = element.Replace("\r", "").Replace("\n", "").Replace("\t", "").Trim();
        if ((processElement.IndexOf("}") > -1 || processElement.IndexOf("]") > -1) && appendToNode != rootNode)
        {
            appendToNode = appendToNode.ParentNode;
        }
        else if (processElement.IndexOf("[") > -1)
        {
            processElement = processElement.Replace(":", "").Replace("[", "").Replace("\"", "").Trim();
            newNode = returnXmlDoc.CreateElement(processElement);
            appendToNode.AppendChild(newNode);
            appendToNode = newNode;
        }
        else if (processElement.IndexOf("{") > -1 && processElement.IndexOf(":") > -1)
        {
            processElement = processElement.Replace(":", "").Replace("{", "").Replace("\"", "").Trim();
            newNode = returnXmlDoc.CreateElement(processElement);
            appendToNode.AppendChild(newNode);
            appendToNode = newNode;
        }
        else
        {
            if (processElement.IndexOf(":") > -1)
            {
                arrElementData = processElement.Replace(": \"", ":").Replace("\",", "").Replace("\"", "").Split(':');
                newNode = returnXmlDoc.CreateElement(arrElementData[0]);
                for (int i = 1; i < arrElementData.Length; i++)
                {
                    newNode.InnerText += arrElementData[i];
                }

                appendToNode.AppendChild(newNode);
            }
        }
    }

    return returnXmlDoc;
}

I would choose an existing and already tested solution. For example this from rxjs in typescript:

function isNumeric(val: any): val is number | string {
  // parseFloat NaNs numeric-cast false positives (null|true|false|"")
  // ...but misinterprets leading-number strings, particularly hex literals ("0x...")
  // subtraction forces infinities to NaN
  // adding 1 corrects loss of precision from parseFloat (#15100)
  return !isArray(val) && (val - parseFloat(val) + 1) >= 0;
}

rxjs/isNumeric.ts

Without rxjs isArray() function and with simplefied typings:

function isNumeric(val: any): boolean {
  return !(val instanceof Array) && (val - parseFloat(val) + 1) >= 0;
}

You should always test such functions with your use cases. If you have special value types, this function may not be your solution. You can test the function here.

Results are:

enum         : CardTypes.Debit   : true
decimal      : 10                : true
hexaDecimal  : 0xf10b            : true
binary       : 0b110100          : true
octal        : 0o410             : true
stringNumber : '10'              : true

string       : 'Hello'           : false
undefined    : undefined         : false
null         : null              : false
function     : () => {}          : false
array        : [80, 85, 75]      : false
turple       : ['Kunal', 2018]   : false
object       : {}                : false

As you can see, you have to be careful, if you use this function with enums.

If anyone wants the TypeScript version shared by the Honorable @SeanVieira here, you can use this:

    public timer(fn: (...args: any[]) => void, countdown: number): { onCancel: () => void, onPause: () => void, onResume: () => void } {
        let ident: NodeJS.Timeout | number;
        let complete = false;
        let totalTimeRun: number;
        const onTimeDiff = (date1: number, date2: number) => {
            return date2 ? date2 - date1 : new Date().getTime() - date1;
        };

        const handlers = {
            onCancel: () => {
                clearTimeout(ident as NodeJS.Timeout);
            },
            onPause: () => {
                clearTimeout(ident as NodeJS.Timeout);

Should do it

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

All the random methods end up calling random.random() so the best way is to call it directly:

[int(1000*random.random()) for i in xrange(10000)]

For example,

• random.randint calls random.randrange.
• random.randrange has a bunch of overhead to check the range before returning istart + istep*int(self.random() * n).

NumPy is much faster still of course.

Don't parse it. Just ask.

import socket

try:
    socket.inet_aton(addr)
    # legal
except socket.error:
    # Not legal

Can you check value of i by putting logger or println(). and check with closing db conn at the end. Rest your code looks fine and it should work.

In each parent LinearLayout for which you want dividers between components, add android:divider="?android:dividerHorizontal" or android:divider="?android:dividerVertical.

Choose appropriate between them as per orientation of your LinearLayout.

Till I know, this resource style is added from Android 4.3.

Exception: java.lang.IllegalStateException: Fragment

DeadlineListFragment{ad2ef970} not attached to Activity

Category: Lifecycle

Description: When doing time-consuming operation in background thread(e.g, AsyncTask), a new Fragment has been created in the meantime, and was detached to the Activity before the background thread finished. The code in UI thread(e.g.,onPostExecute) calls upon a detached Fragment, throwing such exception.

Fix solution:

1. Cancel the background thread when pausing or stopping the Fragment

2. Use isAdded() to check whether the fragment is attached and then to getResources() from activity.

This is what git filter-branch was designed for.

You probably have one .OBJ or .LIB file that's targeted for x64 (that's the module machine type) while you're linking for x86 (that's the target machine type).

Use DUMPBIN /HEADERS on your .OBJ files and check for the machine entry in the FILE HEADER VALUES block.

Actually, you should use either JVM managed Objects or Spring-managed Object to invoke methods. from your above code in your controller class, you are creating a new object to call your service class which has an auto-wired object.

MileageFeeCalculator calc = new MileageFeeCalculator();

so it won't work that way.

The solution makes this MileageFeeCalculator as an auto-wired object in the Controller itself.

Change your Controller class like below.

@Controller
public class MileageFeeController {

    @Autowired
    MileageFeeCalculator calc;  

    @RequestMapping("/mileage/{miles}")
    @ResponseBody
    public float mileageFee(@PathVariable int miles) {
        return calc.mileageCharge(miles);
    }
}

Try this:

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    ComboBox cmb = (ComboBox)sender;
    int selectedIndex = cmb.SelectedIndex;
    int selectedValue = (int)cmb.SelectedValue;

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

the issue is that a DataTemplate isn't part of an element its applied to it.

this means if you bind to the template you're binding to something that has no context.

however if you put a element inside the template then when that element is applied to the parent it gains a context and the binding then works

so this will not work

<DataTemplate >
    <DataTemplate.Resources>
        <CollectionViewSource x:Key="projects" Source="{Binding Projects}" >

but this works perfectly

<DataTemplate >
    <GroupBox Header="Projects">
        <GroupBox.Resources>
            <CollectionViewSource x:Key="projects" Source="{Binding Projects}" >

because after the datatemplate is applied the groupbox is placed in the parent and will have access to its Context

so all you have to do is remove the style from the template and move it into an element in the template

note that the context for a itemscontrol is the item not the control ie ComboBoxItem for ComboBox not the ComboBox itself in which case you should use the controls ItemContainerStyle instead

You must wrap your element in a table-cell, within a table using display.

Like this:

<div>
  <span class='twoline'>Two line text</span>
  <span class='float'>Float right</span>
</div>

and

.float {
    display: table-cell;
    vertical-align: middle;
    text-align: right;
}
.twoline {
    width: 50px;
    display: table-cell;
}
div {
    display: table;
    border: solid 1px blue;
    width: 500px;
    height: 100px;
}

Shown here: http://jsfiddle.net/e8ESb/7/

In C++ you can access fields or methods, using different operators, depending on it's type:

• ClassName::FieldName : class public static field and methods
• ClassInstance.FieldName : accessing a public field (or method) through class reference
• ClassPointer->FieldName : accessing a public field (or method) dereferencing a class pointer

Note that :: should be used with a class name rather than a class instance, since static fields or methods are common to all instances of a class.

class AClass{
public:
static int static_field;
int instance_field;

static void static_method();
void method();
};

then you access this way:

AClass instance;
AClass *pointer = new AClass();

instance.instance_field; //access instance_field through a reference to AClass
instance.method();

pointer->instance_field; //access instance_field through a pointer to AClass
pointer->method();

AClass::static_field;  
AClass::static_method();

I read through this question, and feel the best way to implement useEffect is not mentioned in the answers. Let's say you have a network call, and would like to do something once you have the response. For the sake of simplicity, let's store the network response in a state variable. One might want to use action/reducer to update the store with the network response.

const [data, setData] = useState(null);

/* This would be called on initial page load */
useEffect(()=>{
    fetch(`https://www.reddit.com/r/${subreddit}.json`)
    .then(data => {
        setData(data);
    })
    .catch(err => {
        /* perform error handling if desired */
    });
}, [])

/* This would be called when store/state data is updated */
useEffect(()=>{
    if (data) {
        setPosts(data.children.map(it => {
            /* do what you want */
        }));
    }
}, [data]);

Reference => https://reactjs.org/docs/hooks-effect.html#tip-optimizing-performance-by-skipping-effects

You can clear the error state and empty the stringstream all in one line

std::stringstream().swap(m); // swap m with a default constructed stringstream

This effectively resets m to a default constructed state

if you have table and fields on database you can simply use this command :

php artisan db:seed --class=UsersTableSeeder --database=YOURDATABSE

function loadpage (page_request, containerid)
{
  var loading = document.getElementById ( "loading" ) ;

  // when connecting to server
  if ( page_request.readyState == 1 )
      loading.style.visibility = "visible" ;

  // when loaded successfully
  if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
  {
      document.getElementById(containerid).innerHTML=page_request.responseText ;
      loading.style.visibility = "hidden" ;
  }
}

This is what I ended up using inside my .bat file. Windows only of course.

set CURRENT_DIR=%cd%
mkdir ./directoryToExtractTo
cd ./directoryToExtractTo
jar xvf %CURRENT_DIR%\myJar.jar
cd %CURRENT_DIR%

The pyaudio website has many examples that are pretty short and clear: http://people.csail.mit.edu/hubert/pyaudio/

Update 14th of December 2019 - Main example from the above linked website from 2017:

"""PyAudio Example: Play a WAVE file."""

import pyaudio
import wave
import sys

CHUNK = 1024

if len(sys.argv) < 2:
    print("Plays a wave file.\n\nUsage: %s filename.wav" % sys.argv[0])
    sys.exit(-1)

wf = wave.open(sys.argv[1], 'rb')

p = pyaudio.PyAudio()

stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
                channels=wf.getnchannels(),
                rate=wf.getframerate(),
                output=True)

data = wf.readframes(CHUNK)

while data != '':
    stream.write(data)
    data = wf.readframes(CHUNK)

stream.stop_stream()
stream.close()

p.terminate()

The best solution is:

1. Right click on Computer -> Properties -> Device manager.
2. View -> Show hidden devices.
3. Choose Non-plug and plug drivers -> HTTP -> Disable.
4. Restart your computer.

you can use the function

bind_rows(a,b)

from the dplyr library

BootStrap 4

When using BootStrap 4 the tooltip is appended to the bottom of the body tag. If your tooltip is a child of another tag there is no way to target the tooltip using css. The only way I've found that works is using the inserted.bs.tooltip event and adding a class to the inner div and the arrow. Then you can target the class in css.

// initialize tooltips_x000D_
$('[data-toggle="tooltip"]').tooltip(); _x000D_
_x000D_
// Add the classes to the toolip when it is created_x000D_
$('[data-toggle="tooltip"]').on('inserted.bs.tooltip',function () {_x000D_
    var thisClass = $(this).attr("class");_x000D_
    $('.tooltip-inner').addClass(thisClass);_x000D_
    $('.arrow').addClass(thisClass + "-arrow");_x000D_
});

/* style the tooltip box and arrow based on your class*/_x000D_
.bs-tooltip-left .redTip {_x000D_
    background-color: red !important_x000D_
}_x000D_
.bs-tooltip-left .redTip-arrow::before {_x000D_
    border-left-color: red !important_x000D_
}

To answer your other questions; get the condition to work on every cell in the column and what about blanks?

What about blanks?

Add an extra IF condition to check if the cell is blank or not, if it isn't blank perform the check. =IF(B2="","",B2<=TODAY())

Condition on every cell in column

If you are using Table.query property:

from sqlalchemy import func
Table.query.with_entities(Table.column, func.count(Table.column)).group_by(Table.column).all()

If you are using session.query() method (as stated in miniwark's answer):

from sqlalchemy import func
session.query(Table.column, func.count(Table.column)).group_by(Table.column).all()

You are setting the extra with an array. You are then trying to get a single int.

Your code should be:

int[] arrayB = extras.getIntArray("numbers");

Your example is not a good one in that it is very unlikely that the performance will be signficantly different. In your example readability should trump performance because the performance gain of one vs the other is negligable. The benefits of an array (StringBuffer) are only apparent when you are doing many concatentations. Even then your mileage can very depending on your browser.

Here is a detailed performance analysis that shows performance using all the different JavaScript concatenation methods across many different browsers; String Performance an Analysis

In my case it was because of the url pattern I used

my url was like /ui/project/:parameter1/:parameter2.

I didn't need paramerter2 in all cases of state change. In cases where I didn't need the second parameter my url would be like /ui/project/:parameter1/. And so whenever I had a state change I will have my controller refreshed twice.

The solution was to set parameter2 as empty string and do the state change.

You can pass a method as parameter with method(:function) way. Below is a very simple example:

def double(a)
  return a * 2 
end
=> nil

def method_with_function_as_param( callback, number) 
  callback.call(number) 
end 
=> nil

method_with_function_as_param( method(:double) , 10 ) 
=> 20

try :

sudo su

then

npm i npx 
or 
npi i -g npx

check your npx version by

npx -v

You can also detect it like below

$.isIPhone = function(){
    return ((navigator.platform.indexOf("iPhone") != -1) || (navigator.platform.indexOf("iPod") != -1));

};
$.isIPad = function (){
    return (navigator.platform.indexOf("iPad") != -1);
};
$.isAndroidMobile  = function(){
    var ua = navigator.userAgent.toLowerCase();
    return ua.indexOf("android") > -1 && ua.indexOf("mobile");
};
$.isAndroidTablet  = function(){
    var ua = navigator.userAgent.toLowerCase();
    return ua.indexOf("android") > -1 && !(ua.indexOf("mobile"));
};

If you are manually assembling the XML string use var.ToUniversalTime().ToString("yyyy-MM-dd'T'HH:mm:ss.fffffffZ")); That will output the official XML Date Time format. But you don't have to worry about format if you use the built-in serialization methods.

You could have used DISTINCT or just remove the PARTITION BY portions and use GROUP BY:

SELECT BrandId
       ,SUM(ICount)
       ,TotalICount = SUM(ICount) OVER ()    
       ,Percentage = SUM(ICount) OVER ()*1.0 / SUM(ICount) 
FROM Table 
WHERE DateId  = 20130618
GROUP BY BrandID

Not sure why you are dividing the total by the count per BrandID, if that's a mistake and you want percent of total then reverse those bits above to:

SELECT BrandId
           ,SUM(ICount)
           ,TotalICount = SUM(ICount) OVER ()    
           ,Percentage = SUM(ICount)*1.0 / SUM(ICount) OVER () 
    FROM Table 
    WHERE DateId  = 20130618
    GROUP BY BrandID

New introduction 2

In the previous version of macro "SaveEmailDetails" I used this statement to find Inbox:

Set FolderTgt = CreateObject("Outlook.Application"). _
              GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)

I have since installed a newer version of Outlook and I have discovered that it does not use the default Inbox. For each of my email accounts, it created a separate store (named for the email address) each with its own Inbox. None of those Inboxes is the default.

This macro, outputs the name of the store holding the default Inbox to the Immediate Window:

Sub DsplUsernameOfDefaultStore()

  Dim NS As Outlook.NameSpace
  Dim DefaultInboxFldr As MAPIFolder

  Set NS = CreateObject("Outlook.Application").GetNamespace("MAPI")
  Set DefaultInboxFldr = NS.GetDefaultFolder(olFolderInbox)

  Debug.Print DefaultInboxFldr.Parent.Name

End Sub

On my installation, this outputs: "Outlook Data File".

I have added an extra statement to macro "SaveEmailDetails" that shows how to access the Inbox of any store.

New introduction 1

A number of people have picked up the macro below, found it useful and have contacted me directly for further advice. Following these contacts I have made a few improvements to the macro so I have posted the revised version below. I have also added a pair of macros which together will return the MAPIFolder object for any folder with the Outlook hierarchy. These are useful if you wish to access other than a default folder.

The original text referenced one question by date which linked to an earlier question. The first question has been deleted so the link has been lost. That link was to Update excel sheet based on outlook mail (closed)

Original text

There are a surprising number of variations of the question: "How do I extract data from Outlook emails to Excel workbooks?" For example, two questions up on [outlook-vba] the same question was asked on 13 August. That question references a variation from December that I attempted to answer.

For the December question, I went overboard with a two part answer. The first part was a series of teaching macros that explored the Outlook folder structure and wrote data to text files or Excel workbooks. The second part discussed how to design the extraction process. For this question Siddarth has provided an excellent, succinct answer and then a follow-up to help with the next stage.

What the questioner of every variation appears unable to understand is that showing us what the data looks like on the screen does not tell us what the text or html body looks like. This answer is an attempt to get past that problem.

The macro below is more complicated than Siddarth’s but a lot simpler that those I included in my December answer. There is more that could be added but I think this is enough to start with.

The macro creates a new Excel workbook and outputs selected properties of every email in Inbox to create this worksheet:

Near the top of the macro there is a comment containing eight hashes (#). The statement below that comment must be changed because it identifies the folder in which the Excel workbook will be created.

All other comments containing hashes suggest amendments to adapt the macro to your requirements.

How are the emails from which data is to be extracted identified? Is it the sender, the subject, a string within the body or all of these? The comments provide some help in eliminating uninteresting emails. If I understand the question correctly, an interesting email will have Subject = "Task Completed".

The comments provide no help in extracting data from interesting emails but the worksheet shows both the text and html versions of the email body if they are present. My idea is that you can see what the macro will see and start designing the extraction process.

This is not shown in the screen image above but the macro outputs two versions on the text body. The first version is unchanged which means tab, carriage return, line feed are obeyed and any non-break spaces look like spaces. In the second version, I have replaced these codes with the strings [TB], [CR], [LF] and [NBSP] so they are visible. If my understanding is correct, I would expect to see the following within the second text body:

Activity[TAB]Count[CR][LF]Open[TAB]35[CR][LF]HCQA[TAB]42[CR][LF]HCQC[TAB]60[CR][LF]HAbst[TAB]50 45 5 2 2 1[CR][LF] and so on

Extracting the values from the original of this string should not be difficult.

I would try amending my macro to output the extracted values in addition to the email’s properties. Only when I have successfully achieved this change would I attempt to write the extracted data to an existing workbook. I would also move processed emails to a different folder. I have shown where these changes must be made but give no further help. I will respond to a supplementary question if you get to the point where you need this information.

Good luck.

I looked at the previous answers and they seem like they're working too hard. Maybe scripting support has simply improved. I think the function is expressed like this:

function lastValue(myRange) {
    lastRow = myRange.length;
    for (; myRange[lastRow - 1] == "" && lastRow > 0; lastRow--)
    { /*nothing to do*/ }
    return myRange[lastRow - 1];
}

In my spreadsheet I then use:

= lastValue(E17:E999)

In the function, I get an array of values with one per referenced cell and this just iterates from the end of the array backwards until it finds a non-empty value or runs out of elements. Sheet references should be interpreted before the data is passed to the function. Not fancy enough to handle multi-dimensions, either. The question did ask for the last cell in a single column, so it seems to fit. It will probably die on if you run out of data, too.

Your mileage may vary, but this works for me.

Keys combination:

Ctrl + F5

Syncs the project with Gradle files.

Separate function to make adding event handlers much easier.

function addListener(event, obj, fn) {
    if (obj.addEventListener) {
        obj.addEventListener(event, fn, false);   // modern browsers
    } else {
        obj.attachEvent("on"+event, fn);          // older versions of IE
    }
}

element = document.getElementsByClassName('drill_cursor')[0];

addListener('click', element, function () {
    // Do stuff
});

Take a look at implementation of Java ArrayList. Java ArrayList internally uses a fixed size array and reallocates the array once number of elements exceed current size. You can also implement on similar lines.

note: you may lose values once system restarts.

You can also add system environment variables without Admin rights in Windows 10.

now don't restart, close any opened cmd or powershell, reopen cmd and test by ng version command if you see this it is confirmed working fine.

hope this helps

You can use this way because id can not be sequential in all cases.

SELECT * 
FROM  `ht_news` 
LIMIT 0 , 30

The command is lowercase: touch filename.

Keep in mind that touch will only create a new file if it does not exist! Here's some docs for good measure: http://unixhelp.ed.ac.uk/CGI/man-cgi?touch

If you always want an empty file, one way to do so would be to use:

echo "" > filename

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

You need to either qualify vector with its namespace (which is std), or import the namespace at the top of your CPP file:

using namespace std;

I have been doing PHP for my project, and I can say that the following code works for me. You should try it.

echo '<input type = "text" value = '.$idtest.'>'; 

If you are using VS Code with flutter, you should find it in your app folder, under the android folder:

C:\myappFolder\android

You can run this in the terminal:

./gradlew signingReport

There are several possibilities for concatenating 1D arrays, e.g.,

numpy.r_[a, a],
numpy.stack([a, a]).reshape(-1),
numpy.hstack([a, a]),
numpy.concatenate([a, a])

All those options are equally fast for large arrays; for small ones, concatenate has a slight edge:

The plot was created with perfplot:

import numpy
import perfplot

perfplot.show(
    setup=lambda n: numpy.random.rand(n),
    kernels=[
        lambda a: numpy.r_[a, a],
        lambda a: numpy.stack([a, a]).reshape(-1),
        lambda a: numpy.hstack([a, a]),
        lambda a: numpy.concatenate([a, a]),
    ],
    labels=["r_", "stack+reshape", "hstack", "concatenate"],
    n_range=[2 ** k for k in range(19)],
    xlabel="len(a)",
)

temp = bankAccNos.contains(no) ? 1 : 2;

$('input:text').filter(function() { return this.value.length > 0; });

The code of Ellbar works! You need only add using.

1 - using Microsoft.AspNet.Identity;

And... the code of Ellbar:

2 - string currentUserId = User.Identity.GetUserId(); ApplicationUser currentUser = db.Users.FirstOrDefault(x => x.Id == currentUserId);

With this code (in currentUser), you work the general data of the connected user, if you want extra data... see this link

@GáborNagy's comment on another post was the simplest solution I could find and worked like a charm for me, since he brought a jsfiddle I'm copying it here with a small addition:

CSS:

#wrapper {
    display: table;
    height: 150px;
    width: 800px;
    border: 1px solid red;
}

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

HTML:

<div id="wrapper">
    <div id="cell">
        <div class="content">
            Content goes here
        </div>
    </div>
</div>

If you wish to also align it horizontally you'd have to add another div "inner-cell" inside the "cell" div, and give it this style:

#inner-cell{
      width: 250px;
      display: block;
      margin: 0 auto;
}

Well, the only thing that I can tell you about are getter:

var foo = {_x000D_
  a: 5,_x000D_
  b: 6,_x000D_
  get c() {_x000D_
    return this.a + this.b;_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log(foo.c) // 11

This is a syntactic extension introduced by the ECMAScript 5th Edition Specification, the syntax is supported by most modern browsers (including IE9).

AES is a symmetric cryptographic algorithm, while RSA is an asymmetric (or public key) cryptographic algorithm. Encryption and decryption is done with a single key in AES, while you use separate keys (public and private keys) in RSA. The strength of a 128-bit AES key is roughly equivalent to 2600-bits RSA key.

You can adjust the plot margins with plot.margin in theme() and then move your axis labels and title with the vjust argument of element_text(). For example :

library(ggplot2)
library(grid)
qplot(rnorm(100)) +
    ggtitle("Title") +
    theme(axis.title.x=element_text(vjust=-2)) +
    theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
    theme(plot.title=element_text(size=15, vjust=3)) +
    theme(plot.margin = unit(c(1,1,1,1), "cm"))

will give you something like this :

If you want more informations about the different theme() parameters and their arguments, you can just enter ?theme at the R prompt.

You can't access Temporary Tables from within a SQL Function. You will need to use table variables so essentially:

ALTER FUNCTION FnGetCompanyIdWithCategories()
RETURNS  @rtnTable TABLE 
(
    -- columns returned by the function
    ID UNIQUEIDENTIFIER NOT NULL,
    Name nvarchar(255) NOT NULL
)
AS
BEGIN
DECLARE @TempTable table (id uniqueidentifier, name nvarchar(255)....)

insert into @myTable 
select from your stuff

--This select returns data
insert into @rtnTable
SELECT ID, name FROM @mytable 
return
END

Edit

Based on comments to this question here is my recommendation. You want to join the results of either a procedure or table-valued function in another query. I will show you how you can do it then you pick the one you prefer. I am going to be using sample code from one of my schemas, but you should be able to adapt it. Both are viable solutions first with a stored procedure.

declare @table as table (id int, name nvarchar(50),templateid int,account nvarchar(50))

insert into @table
execute industry_getall

select * 
from @table 
inner join [user] 
    on account=[user].loginname

In this case, you have to declare a temporary table or table variable to store the results of the procedure. Now Let's look at how you would do this if you were using a UDF

select *
from fn_Industry_GetAll()
inner join [user] 
    on account=[user].loginname

As you can see the UDF is a lot more concise easier to read, and probably performs a little bit better since you're not using the secondary temporary table (performance is a complete guess on my part).

If you're going to be reusing your function/procedure in lots of other places, I think the UDF is your best choice. The only catch is you will have to stop using #Temp tables and use table variables. Unless you're indexing your temp table, there should be no issue, and you will be using the tempDb less since table variables are kept in memory.

Incase 'Instant Run' is enable, then just disable it.

Consider a right angled triangle. We label the hypotenuse r, the horizontal side y and the vertical side x. The angle of interest α is the angle between x and r.

C++ atan2(y, x) will give us the value of angle α in radians. atan is used if we only know or are interested in y/x not y and x individually. So if p = y/x then to get α we'd use atan(p).

You cannot use atan2 to determine the quadrant, you can use atan2 only if you already know which quadrant your in! In particular positive x and y imply the first quadrant, positive y and negative x, the second and so on. atan or atan2 themselves simply return a positive or a negative number, nothing more.

I have done something like this abstract class that can be used in place of TextView.OnEditorActionListener type.

abstract class OnTextEndEditingListener : TextView.OnEditorActionListener {

    override fun onEditorAction(textView: TextView?, actionId: Int, event: KeyEvent?): Boolean {

        if(actionId == EditorInfo.IME_ACTION_SEARCH ||
                actionId == EditorInfo.IME_ACTION_DONE ||
                actionId == EditorInfo.IME_ACTION_NEXT ||
                event != null &&
                event.action == KeyEvent.ACTION_DOWN &&
                event.keyCode == KeyEvent.KEYCODE_ENTER) {

            if(event == null || !event.isShiftPressed) {
                // the user is done typing.
                return onTextEndEditing(textView, actionId, event)
            }
        }
        return false // pass on to other listeners
    }

    abstract fun onTextEndEditing(textView: TextView?, actionId: Int, event: KeyEvent?) : Boolean
}

If anyone is looking for the angular version of this answer then I would suggest creating a directive would be a great idea.

NOTE: ngx-bootstrap is used.

import { Directive, Host, Self, Optional, Input, Renderer2, OnInit, ElementRef } from '@angular/core';
import { CarouselComponent } from 'ngx-bootstrap/carousel';

@Directive({
  selector: '[appCarouselSwipe]'
})
export class AppCarouselSwipeDirective implements OnInit {
  @Input() swipeThreshold = 50;
  private start: number;
  private stillMoving: boolean;
  private moveListener: Function;

  constructor(
    @Host() @Self() @Optional() private carousel: CarouselComponent,
    private renderer: Renderer2,
    private element: ElementRef
  ) {
  }

  ngOnInit(): void {
    if ('ontouchstart' in document.documentElement) {
      this.renderer.listen(this.element.nativeElement, 'touchstart', this.onTouchStart.bind(this));
      this.renderer.listen(this.element.nativeElement, 'touchend', this.onTouchEnd.bind(this));
    }
  }

  private onTouchStart(e: TouchEvent): void {
    if (e.touches.length === 1) {
      this.start = e.touches[0].pageX;
      this.stillMoving = true;
      this.moveListener = this.renderer.listen(this.element.nativeElement, 'touchmove', this.onTouchMove.bind(this));
    }
  }

  private onTouchMove(e: TouchEvent): void {
    if (this.stillMoving) {
      const x = e.touches[0].pageX;
      const difference = this.start - x;
      if (Math.abs(difference) >= this.swipeThreshold) {
        this.cancelTouch();
        if (difference > 0) {
          if (this.carousel.activeSlide < this.carousel.slides.length - 1) {
            this.carousel.activeSlide = this.carousel.activeSlide + 1;
          }
        } else {
          if (this.carousel.activeSlide > 0) {
            this.carousel.activeSlide = this.carousel.activeSlide - 1;
          }
        }
      }
    }
  }

  private onTouchEnd(e: TouchEvent): void {
    this.cancelTouch();
  }

  private cancelTouch() {
    if (this.moveListener) {
      this.moveListener();
      this.moveListener = undefined;
    }
    this.start = null;
    this.stillMoving = false;
  }
}

For Kotlin users, I created a ImageStorageManager class which will handle save, get and delete actions for images easily:

class ImageStorageManager {
    companion object {
        fun saveToInternalStorage(context: Context, bitmapImage: Bitmap, imageFileName: String): String {
            context.openFileOutput(imageFileName, Context.MODE_PRIVATE).use { fos ->
                bitmapImage.compress(Bitmap.CompressFormat.PNG, 25, fos)
            }
            return context.filesDir.absolutePath
        }

        fun getImageFromInternalStorage(context: Context, imageFileName: String): Bitmap? {
            val directory = context.filesDir
            val file = File(directory, imageFileName)
            return BitmapFactory.decodeStream(FileInputStream(file))
        }

        fun deleteImageFromInternalStorage(context: Context, imageFileName: String): Boolean {
            val dir = context.filesDir
            val file = File(dir, imageFileName)
            return file.delete()
        }
    }

Good question. But I think there is no good answer which fits your criteria. The best I can think of is to use an extra vars file.

A task like this:

- include_vars: concat.yml

And in concat.yml you have your definition:

newvar: "{{ var1 }}-{{ var2 }}-{{ var3 }}"

No. JavaScript is automatically garbage collected; the object's memory will be reclaimed only if the GC decides to run and the object is eligible for collection.

Seeing as that will happen automatically as required, what would be the purpose of reclaiming the memory explicitly?

I've used this function to merge objects in the past, I use it to add or update existing properties on obj1 with values from obj2:

var _mergeRecursive = function(obj1, obj2) {

      //iterate over all the properties in the object which is being consumed
      for (var p in obj2) {
          // Property in destination object set; update its value.
          if ( obj2.hasOwnProperty(p) && typeof obj1[p] !== "undefined" ) {
            _mergeRecursive(obj1[p], obj2[p]);

          } else {
            //We don't have that level in the heirarchy so add it
            obj1[p] = obj2[p];

          }
     }
}

It will handle multiple levels of hierarchy as well as single level objects. I used it as part of a utility library for manipulating JSON objects. You can find it here.

Clean Solution and Build again In my case, whatever the previous settings were blocking due to mismatch. I imported a new project and build it, tried changing versions and all. clean the solutions and build worked for me.

In JPQL the same is actually true in the spec. The JPA spec does not allow an alias to be given to a fetch join. The issue is that you can easily shoot yourself in the foot with this by restricting the context of the join fetch. It is safer to join twice.

This is normally more an issue with ToMany than ToOnes. For example,

Select e from Employee e 
join fetch e.phones p 
where p.areaCode = '613'

This will incorrectly return all Employees that contain numbers in the '613' area code but will left out phone numbers of other areas in the returned list. This means that an employee that had a phone in the 613 and 416 area codes will loose the 416 phone number, so the object will be corrupted.

Granted, if you know what you are doing, the extra join is not desirable, some JPA providers may allow aliasing the join fetch, and may allow casting the Criteria Fetch to a Join.

We can use title() function with negative line value to bring down the title.

See this example:

plot(1, 1)
title("Title", line = -2)

I had to write a simple script for a carousel to detect swipe left or right.

I utilised Pointer Events instead of Touch Events.

I hope this is useful to individuals and I welcome any insights to improve my code; I feel rather sheepish to join this thread with significantly superior JS developers.

function getSwipeX({elementId}) {

  this.e               = document.getElementsByClassName(elementId)[0];
  this.initialPosition = 0;
  this.lastPosition    = 0;
  this.threshold       = 200;
  this.diffInPosition  = null;
  this.diffVsThreshold = null;
  this.gestureState    = 0;

  this.getTouchStart = (event) => {
    event.preventDefault();
    if (window.PointerEvent) {
      this.e.setPointerCapture(event.pointerId);
    }
    return this.initalTouchPos = this.getGesturePoint(event);
  }

  this.getTouchMove  = (event) => {
    event.preventDefault();
    return this.lastPosition = this.getGesturePoint(event);
  }

  this.getTouchEnd   = (event) => {
    event.preventDefault();
    if (window.PointerEvent) {
      this.e.releasePointerCapture(event.pointerId);
    }
    this.doSomething();
    this.initialPosition = 0;
  }

  this.getGesturePoint = (event) => {
    this.point = event.pageX
    return this.point;
  }

  this.whatGestureDirection = (event) => {
    this.diffInPosition  = this.initalTouchPos - this.lastPosition;
    this.diffVsThreshold = Math.abs(this.diffInPosition) > this.threshold;
    (Math.sign(this.diffInPosition) > 0) ? this.gestureState = 'L' : (Math.sign(this.diffInPosition) < 0) ? this.gestureState = 'R' : this.gestureState = 'N';
    
    return [this.diffInPosition, this.diffVsThreshold, this.gestureState];
  }

  this.doSomething = (event) => {
    let [gestureDelta,gestureThreshold,gestureDirection] = this.whatGestureDirection();

    // USE THIS TO DEBUG
    console.log(gestureDelta,gestureThreshold,gestureDirection);

    if (gestureThreshold) {
      (gestureDirection == 'L') ? // LEFT ACTION : // RIGHT ACTION
    }
  }

  if (window.PointerEvent) {
    this.e.addEventListener('pointerdown', this.getTouchStart, true);
    this.e.addEventListener('pointermove', this.getTouchMove, true);
    this.e.addEventListener('pointerup', this.getTouchEnd, true);
    this.e.addEventListener('pointercancel', this.getTouchEnd, true);
  }
}

You can call the function using new.

window.addEventListener('load', () => {
  let test = new getSwipeX({
    elementId: 'your_div_here'
  });
})

You need to use a constant.

CONST NumberOfZombies = 20000
Dim Zombies(NumberOfZombies) As Zombies

or if you want to use a variable you have to do it this way:

Dim NumberOfZombies As Integer
NumberOfZombies = 20000

Dim Zombies() As Zombies

ReDim Zombies(NumberOfZombies)

Here's what I did. I wanted a HTML page setup on our network so I wouldn't have to navigate to various folders to install or upgrade our apps. So what I did was setup a .bat file on our "shared" drive that everyone has access to, in that .bat file I had this code:

start /d "\\server\Software\" setup.exe

The HTML code was:

<input type="button" value="Launch Installer" onclick="window.open('file:///S:Test/Test.bat')" />

(make sure your slashes are correct, I had them the other way and it didn't work)

I preferred to launch the EXE directly but that wasn't possible, but the .bat file allowed me around that. Wish it worked in FF or Chrome, but only IE.

using indices, for loops and formatting:

import numpy as np

def printMatrix(a):
   print "Matrix["+("%d" %a.shape[0])+"]["+("%d" %a.shape[1])+"]"
   rows = a.shape[0]
   cols = a.shape[1]
   for i in range(0,rows):
      for j in range(0,cols):
         print "%6.f" %a[i,j],
      print
   print      


def printMatrixE(a):
   print "Matrix["+("%d" %a.shape[0])+"]["+("%d" %a.shape[1])+"]"
   rows = a.shape[0]
   cols = a.shape[1]
   for i in range(0,rows):
      for j in range(0,cols):
         print("%6.3f" %a[i,j]),
      print
   print      


inf = float('inf')
A = np.array( [[0,1.,4.,inf,3],
     [1,0,2,inf,4],
     [4,2,0,1,5],
     [inf,inf,1,0,3],
     [3,4,5,3,0]])

printMatrix(A)    
printMatrixE(A)    

which yields the output:

Matrix[5][5]
     0      1      4    inf      3
     1      0      2    inf      4
     4      2      0      1      5
   inf    inf      1      0      3
     3      4      5      3      0

Matrix[5][5]
 0.000  1.000  4.000    inf  3.000
 1.000  0.000  2.000    inf  4.000
 4.000  2.000  0.000  1.000  5.000
   inf    inf  1.000  0.000  3.000
 3.000  4.000  5.000  3.000  0.000

I had the same solution as gregpress answer, but my draggable items used a class instead of an id. It seems to work.

var $target = $(event.target);  
if( $target.hasClass('draggable') ) {  
    event.preventDefault();  
}

valign="top" should do the work.

<tr>_x000D_
  <td valign="top">Description</td>_x000D_
</tr>

Maybe this is a bit redundant, but no one appeared to have mentioned this as a solution.

As a beginner in SQL I find that when using a BEGIN and END SSMS usually adds a squiggly line with incorrect syntax near 'END' to END, simply because there's no content in between yet. If you're just setting up BEGIN and END to get started and add the actual query later, then simply add a bogus PRINT statement so SSMS stops bothering you.

For example:

IF (1=1)
BEGIN
  PRINT 'BOGUS'
END

The following will indeed set you on the wrong track, thinking you made a syntax error which in this case just means you still need to add content in between BEGIN and END:

IF (1=1)
BEGIN
END

I haven't had a problem just using Unix-style path separators, even on Windows (though it is good practice to check File.separatorChar).

The technique of using ClassLoader.getResource() is best for read-only resources that are going to be loaded from JAR files. Sometimes, you can programmatically determine the application directory, which is useful for admin-configurable files or server applications. (Of course, user-editable files should be stored somewhere in the System.getProperty("user.home") directory.)

As mentioned by others, PHP 7 introduces support for the \u Unicode syntax directly.

As also mentioned by others, the only way to obtain a string value from any sensible Unicode character description in PHP, is by converting it from something else (e.g. JSON parsing, HTML parsing or some other form). But this comes at a run-time performance cost.

However, there is one other option. You can encode the character directly in PHP with \x binary escaping. The \x escape syntax is also supported in PHP 5.

This is especially useful if you prefer not to enter the character directly in a string through its natural form. For example, if it is an invisible control character, or other hard to detect whitespace.

First, a proof example:

// Unicode Character 'HAIR SPACE' (U+200A)
$htmlEntityChar = " ";
$realChar = html_entity_decode($htmlEntityChar);
$phpChar = "\xE2\x80\x8A";
echo 'Proof: ';
var_dump($realChar === $phpChar); // bool(true)

Note that, as mentioned by Pacerier in another answer, this binary code is unique to a specific character encoding. In the above example, \xE2\x80\x8A is the binary coding for U+200A in UTF-8.

The next question is, how do you get from U+200A to \xE2\x80\x8A?

Below is a PHP script to generate the escape sequence for any character, based on either a JSON string, HTML entity, or any other method once you have it as a native string.

function str_encode_utf8binary($str) {
    /** @author Krinkle 2018 */
    $output = '';
    foreach (str_split($str) as $octet) {
        $ordInt = ord($octet);
        // Convert from int (base 10) to hex (base 16), for PHP \x syntax
        $ordHex = base_convert($ordInt, 10, 16);
        $output .= '\x' . $ordHex;
    }
    return $output;
}

function str_convert_html_to_utf8binary($str) {
    return str_encode_utf8binary(html_entity_decode($str));
}
function str_convert_json_to_utf8binary($str) {
    return str_encode_utf8binary(json_decode($str));
}

// Example for raw string: Unicode Character 'INFINITY' (U+221E)
echo str_encode_utf8binary('8') . "\n";
// \xe2\x88\x9e

// Example for HTML: Unicode Character 'HAIR SPACE' (U+200A)
echo str_convert_html_to_utf8binary(' ') . "\n";
// \xe2\x80\x8a

// Example for JSON: Unicode Character 'HAIR SPACE' (U+200A)
echo str_convert_json_to_utf8binary('"\u200a"') . "\n";
// \xe2\x80\x8a

@GusDeCool or anyone else trying to replace more than one thousands separators, one way to do it is a regex global replace: /foo/g. Just remember that . is a metacharacter, so you have to escape it or put it in brackets (\. or [.]). Here's one option:

var str = '6.000.000';
str.replace(/[.]/g,",");

Consider this code,

int some_int = 100;

while(some_int == 100)
{
   //your code
}

When this program gets compiled, the compiler may optimize this code, if it finds that the program never ever makes any attempt to change the value of some_int, so it may be tempted to optimize the while loop by changing it from while(some_int == 100) to something which is equivalent to while(true) so that the execution could be fast (since the condition in while loop appears to be true always). (if the compiler doesn't optimize it, then it has to fetch the value of some_int and compare it with 100, in each iteration which obviously is a little bit slow.)

However, sometimes, optimization (of some parts of your program) may be undesirable, because it may be that someone else is changing the value of some_int from outside the program which compiler is not aware of, since it can't see it; but it's how you've designed it. In that case, compiler's optimization would not produce the desired result!

So, to ensure the desired result, you need to somehow stop the compiler from optimizing the while loop. That is where the volatile keyword plays its role. All you need to do is this,

volatile int some_int = 100; //note the 'volatile' qualifier now!

In other words, I would explain this as follows:

volatile tells the compiler that,

"Hey compiler, I'm volatile and, you know, I can be changed by some XYZ that you're not even aware of. That XYZ could be anything. Maybe some alien outside this planet called program. Maybe some lightning, some form of interrupt, volcanoes, etc can mutate me. Maybe. You never know who is going to change me! So O you ignorant, stop playing an all-knowing god, and don't dare touch the code where I'm present. Okay?"

Well, that is how volatile prevents the compiler from optimizing code. Now search the web to see some sample examples.

Quoting from the C++ Standard ($7.1.5.1/8)

[..] volatile is a hint to the implementation to avoid aggressive optimization involving the object because the value of the object might be changed by means undetectable by an implementation.[...]

Does making a struct volatile make all its members volatile?

One of the best well-documented example I found.

I think the default place for access logs is

%SystemDrive%\inetpub\logs\LogFiles

Otherwise, check under IIS Manager, select the computer on the left pane, and in the middle pane, go under "Logging" in the IIS area. There you will se the default location for all sites (this is however overridable on all sites)

You could also look into

%SystemDrive%\Windows\System32\LogFiles\HTTPERR

Which will contain similar log files that only represents errors.

Suppose we have a generator:

def gen():
    for i in range(10):
        yield i

We can wrap the generator, along with the known length, in an object:

import itertools
class LenGen(object):
    def __init__(self,gen,length):
        self.gen=gen
        self.length=length
    def __call__(self):
        return itertools.islice(self.gen(),self.length)
    def __len__(self):
        return self.length

lgen=LenGen(gen,10)

Instances of LenGen are generators themselves, since calling them returns an iterator.

Now we can use the lgen generator in place of gen, and access len(lgen) as well:

def new_gen():
    for i in lgen():
        yield float(i)/len(lgen)

for i in new_gen():
    print(i)

I also faced this same issue while working in my development environment, the problem was that I left host: localhost commented out in the config/database.yml file.

So my application could not connect to the PostgreSQL database, simply uncommenting it solved the issue.

development:
  <<: *default
  database: database_name

  username: database_username 

  password: database_password

  host: localhost

That's all.

I hope this helps

Express makes this kind of stuff really intuitive. The syntax looks like below :

var app = require('express').createServer();
app.get("/string", function(req, res) {
    var strings = ["rad", "bla", "ska"]
    var n = Math.floor(Math.random() * strings.length)
    res.send(strings[n])
})
app.listen(8001)

If you're using jQuery on the client side you can do something like this:

$.get("/string", function(string) {
    alert(string)
})

Use the ensure_ascii=False switch to json.dumps(), then encode the value to UTF-8 manually:

>>> json_string = json.dumps("??? ????", ensure_ascii=False).encode('utf8')
>>> json_string
b'"\xd7\x91\xd7\xa8\xd7\x99 \xd7\xa6\xd7\xa7\xd7\x9c\xd7\x94"'
>>> print(json_string.decode())
"??? ????"

If you are writing to a file, just use json.dump() and leave it to the file object to encode:

with open('filename', 'w', encoding='utf8') as json_file:
    json.dump("??? ????", json_file, ensure_ascii=False)

Caveats for Python 2

For Python 2, there are some more caveats to take into account. If you are writing this to a file, you can use io.open() instead of open() to produce a file object that encodes Unicode values for you as you write, then use json.dump() instead to write to that file:

with io.open('filename', 'w', encoding='utf8') as json_file:
    json.dump(u"??? ????", json_file, ensure_ascii=False)

Do note that there is a bug in the json module where the ensure_ascii=False flag can produce a mix of unicode and str objects. The workaround for Python 2 then is:

with io.open('filename', 'w', encoding='utf8') as json_file:
    data = json.dumps(u"??? ????", ensure_ascii=False)
    # unicode(data) auto-decodes data to unicode if str
    json_file.write(unicode(data))

In Python 2, when using byte strings (type str), encoded to UTF-8, make sure to also set the encoding keyword:

>>> d={ 1: "??? ????", 2: u"??? ????" }
>>> d
{1: '\xd7\x91\xd7\xa8\xd7\x99 \xd7\xa6\xd7\xa7\xd7\x9c\xd7\x94', 2: u'\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4'}

>>> s=json.dumps(d, ensure_ascii=False, encoding='utf8')
>>> s
u'{"1": "\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4", "2": "\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4"}'
>>> json.loads(s)['1']
u'\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4'
>>> json.loads(s)['2']
u'\u05d1\u05e8\u05d9 \u05e6\u05e7\u05dc\u05d4'
>>> print json.loads(s)['1']
??? ????
>>> print json.loads(s)['2']
??? ????

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

In my humble opinion, first, you have to make sure you have any kind of Node version installed. For that type:

nvm ls

And if you don't get any versions it means I was right :) Then you have to type:

nvm install <node_version**>

** the actual version you can find in Node website

Then you will have Node and you will be able to use npm commands

To be clear there are 4 types of caches you can clear depending upon your case.

php artisan cache:clear

You can run the above statement in your console when you wish to clear the application cache. What it does is that this statement clears all caches inside storage\framework\cache.

php artisan route:cache

This clears your route cache. So if you have added a new route or have changed a route controller or action you can use this one to reload the same.

php artisan config:cache 

This will clear the caching of the env file and reload it

php artisan view:clear 

This will clear the compiled view files of your application.

For Shared Hosting

Most of the shared hosting providers don't provide SSH access to the systems. In such a case you will need to create a route and call the following line as below:

Route::get('/clear-cache', function() {
    Artisan::call('cache:clear');
    return "All cache cleared";
});

All I had to do was:

1. Set the constraints to the top, left, and right of the textView.
2. Disable scrolling in Storyboard.

This allows autolayout to dynamically size the textView based on its content.

I found this php-only and invariable solution which works both with http and cli :

Define a function :

function forbidDirectAccess($file) {
    $self = getcwd()."/".trim($_SERVER["PHP_SELF"], "/");
    (substr_compare($file, $self, -strlen($self)) != 0) or die('Restricted access');
}

Call the function in the file you want to prevent direct access to :

forbidDirectAccess(__FILE__);

Most of the solutions given above to this question do not work in Cli mode.

As already stated by Jason Cohen, the Java Language Specification defines what a legal identifier is in section 3.8:

"An identifier is an unlimited-length sequence of Java letters and Java digits, the first of which must be a Java letter. [...] A 'Java letter' is a character for which the method Character.isJavaIdentifierStart(int) returns true. A 'Java letter-or-digit' is a character for which the method Character.isJavaIdentifierPart(int) returns true."

This hopefully answers your second question. Regarding your first question; I've been taught both by teachers and (as far as I can remember) Java compilers that a Java class name should be an identifier that begins with a capital letter A-Z, but I can't find any reliable source on this. When trying it out with OpenJDK there are no warnings when beginning class names with lower-case letters or even a $-sign. When using a $-sign, you do have to escape it if you compile from a bash shell, however.

Since it isn't practical to put code in a comment, in response to your comment in Eric's answer that it's not working for you...

I just ran the following on a SQL 2005 box (sorry, no 2000 handy) with default settings and it worked without error:

CREATE TABLE dbo.Test_Identity_Insert
(
    id  INT IDENTITY NOT NULL,
    my_string   VARCHAR(20) NOT NULL,
    CONSTRAINT PK_Test_Identity_Insert PRIMARY KEY CLUSTERED (id)
)
GO

INSERT INTO dbo.Test_Identity_Insert VALUES ('test')
GO

SELECT * FROM dbo.Test_Identity_Insert
GO

Are you perhaps sending the ID value over in your values list? I don't think that you can make it ignore the column if you actually pass a value for it. For example, if your table has 6 columns and you want to ignore the IDENTITY column you can only pass 5 values.

Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

Jonathan from the ExcelCentral forums suggests:

=WEEKNUM(A1,2)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),2)+1 

This formula extracts the week of the year [...] and then subtracts it from the week of the first day in the month to get the week of the month. You can change the day that weeks begin by changing the second argument of both WEEKNUM functions (set to 2 [for Monday] in the above example). For weeks beginning on Sunday, use:

=WEEKNUM(A1,1)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),1)+1

For weeks beginning on Tuesday, use:

=WEEKNUM(A1,12)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),12)+1

etc.

I like it better because it's using the built in week calculation functionality of Excel (WEEKNUM).

Kotlin solution, based on what others wrote here:

    fun isTableExists(database: SQLiteDatabase, tableName: String): Boolean {
        database.rawQuery("select DISTINCT tbl_name from sqlite_master where tbl_name = '$tableName'", null)?.use {
            return it.count > 0
        } ?: return false
    }

If your VARCHAR column contains empty strings (which are not the same as NULL for PostgreSQL as you might recall) you will have to use something in the line of the following to set a default:

ALTER TABLE presales ALTER COLUMN code TYPE NUMERIC(10,0)
            USING COALESCE(NULLIF(code, '')::NUMERIC, 0);

(found with the help of this answer)

[myButton setBackgroundColor:[UIColor blueColor]]; [myButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

It's possible change this way or going on Storyboard and change background on options in right side.

'a' in vars() or 'a' in globals()

if you want to be pedantic, you can check the builtins too
'a' in vars(__builtins__)

Many people set their cookie path to /. That will cause every favicon request to send a copy of the sites cookies, at least in chrome. Addressing your favicon to your cookieless domain should correct this.

<link rel="icon" href="https://cookieless.MySite.com/favicon.ico" type="image/x-icon" />

Depending on how much traffic you get, this may be the most practical reason for adding the link.

Info on setting up a cookieless domain:

Good question. Yes, one can do this more efficiently. Your CPU can extract both the quotient and the remainder of the ratio of two integers in a single operation. In <stdlib.h>, the function that exposes this CPU operation is called div(). In your psuedocode, you'd use it something like this:

function to_tuple(x):
    qr = div(x, 1000)
    ms = qr.rem
    qr = div(qr.quot, 60)
    s  = qr.rem
    qr = div(qr.quot, 60)
    m  = qr.rem
    h  = qr.quot

A less efficient answer would use the / and % operators separately. However, if you need both quotient and remainder, anyway, then you might as well call the more efficient div().

you can use below groovy code for maps with foreachloop

def map=[key1:'value1',key2:'value2']

for(item in map)
{
log.info item.value // this will print value1 value2
log.info item // this will print key1=value1 key2=value2
}

Here's another way: this adds a circle to the current axes, plot or image or whatever :

from matplotlib.patches import Circle  # $matplotlib/patches.py

def circle( xy, radius, color="lightsteelblue", facecolor="none", alpha=1, ax=None ):
    """ add a circle to ax= or current axes
    """
        # from .../pylab_examples/ellipse_demo.py
    e = Circle( xy=xy, radius=radius )
    if ax is None:
        ax = pl.gca()  # ax = subplot( 1,1,1 )
    ax.add_artist(e)
    e.set_clip_box(ax.bbox)
    e.set_edgecolor( color )
    e.set_facecolor( facecolor )  # "none" not None
    e.set_alpha( alpha )

(The circles in the picture get squashed to ellipses because imshow aspect="auto" ).

Yes.

new ArrayList<String>(){{
   add("A");
   add("B");
}}

What this is actually doing is creating a class derived from ArrayList<String> (the outer set of braces do this) and then declare a static initialiser (the inner set of braces). This is actually an inner class of the containing class, and so it'll have an implicit this pointer. Not a problem unless you want to serialise it, or you're expecting the outer class to be garbage collected.

I understand that Java 7 will provide additional language constructs to do precisely what you want.

EDIT: recent Java versions provide more usable functions for creating such collections, and are worth investigating over the above (provided at a time prior to these versions)

You cannot simply assign value to a character in the string. Use this method to replace value of a particular character:

name = "India"
result=name .replace("d",'*')

Output: In*ia

Also, if you want to replace say * for all the occurrences of the first character except the first character, eg. string = babble output = ba**le

Code:

name = "babble"
front= name [0:1]
fromSecondCharacter = name [1:]
back=fromSecondCharacter.replace(front,'*')
return front+back

The at command exists specifically for this purpose (unlike cron which is intended for scheduling recurring tasks).

There are several ways to UPDATE using sqlalchemy

1) user.no_of_logins += 1
   session.commit()

2) session.query().\
       filter(User.username == form.username.data).\
       update({"no_of_logins": (User.no_of_logins +1)})
   session.commit()

3) conn = engine.connect()
   stmt = User.update().\
       values(no_of_logins=(User.no_of_logins + 1)).\
       where(User.username == form.username.data)
   conn.execute(stmt)

4) setattr(user, 'no_of_logins', user.no_of_logins+1)
   session.commit()

This call will give you the information you want.

From the GUI: open your server properties, go to Database Settings, and see Database default locations.

Note that you can drop your database files wherever you like, though it seems cleaner to keep them in the default directory.

I know this is an old question but if you are building iOS SDK 4+ then you can use blocks to do this with very little effort and make it more readable:

double delayInSeconds = 2.0;
int primitiveValue = 500;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
    [self doSomethingWithPrimitive:primitiveValue];     
});

Replace this line:

StreamWriter sw = new StreamWriter("c:/file.txt");

with this code:

StreamWriter sw = File.AppendText("c:/file.txt");

and then write your line to the text file like this:

sw.WriteLine("text content");

  var data = JSON.stringify
            ({
            'StrContactDetails': Details,
            'IsPrimary': true
            })

Here is a demo. Use position:fixed; top:0; left:0; so the header always stay on top.

?#header {
    background:red;
    height:50px;
    width:100%;
    position:fixed;
    top:0;
    left:0;    
}.scroller {
    height:300px; 
    overflow:scroll;    
}

use & in place of &

change to

<string name="magazine">Newspaper &amp; Magazines</string>

you can specify which column to sort by, with following steps:

steps:
* top
* shift + F
* select a column from the list
    e.g. n means sort by memory,
* press enter
* ok

select * from table where value % 2 = 1 works fine in mysql.
