You call tarfile.open with mode='w:gz', meaning "Open for gzip compressed writing."

You'll probably want to end the filename (the name argument to open) with .tar.gz, but that doesn't affect compression abilities.

BTW, you usually get better compression with a mode of 'w:bz2', just like tar can usually compress even better with bzip2 than it can compress with gzip.

I see what you are trying to ask and I think this is the simplest answer to what you are looking for, given you might not know how many key pairs your are being sent.

Simple Key Pair JSON structure

var data = {
    'XXXXXX' : '100.0',
    'YYYYYYY' : '200.0',
    'ZZZZZZZ' : '500.0',
}

Usage JavaScript code to access the key pairs

for (var key in data) 
  { if (!data.hasOwnProperty(key))
    { continue; } 
    console.log(key + ' -> ' +  data[key]);
  };

Console output should look like this

XXXXXX -> 100.0 
YYYYYYY -> 200.0 
ZZZZZZZ -> 500.0

Here is a JSFiddle to show how it works.

Integer.parseInt can just return int as native type.

Integer.valueOf may actually need to allocate an Integer object, unless that integer happens to be one of the preallocated ones. This costs more.

If you need just native type, use parseInt. If you need an object, use valueOf.

Also, because of this potential allocation, autoboxing isn't actually good thing in every way. It can slow down things.

I just went through troubleshooting this issue, and in my case it indeed was related to redirects, but not related to incorrect settings in my CloudFront Origin or Behavior. This will happen if your origin server is still redirecting to origin URLs, and not what you have set up for your cloudfront URLs. Seems this is very common if you forget to change configs. For example lets say if you have www.yoursite.com CNAME to your cloudfront distribution, with an origin of www.yoursiteorigin.com. Obviously people will come to www.yoursite.com. But if your code tries to redirect to any page on www.yoursiteorigin.com you WILL get this error.

For me, my origin was still doing the http->https redirects to my origin URLs and not my Cloudfront URLs.

XAMPP for linux and mac comes with ProFTPD. Make sure to start the service from XAMPP control panel -> manage servers.

Further complete instructions can be found at localhost XAMPP dashboard -> How-to guides -> Configure FTP Access. I have pasted them below :

1. Open a new Linux terminal and ensure you are logged in as root.

2. Create a new group named ftp. This group will contain those user accounts allowed to upload files via FTP.

groupadd ftp

3. Add your account (in this example, susan) to the new group. Add other users if needed.

usermod -a -G ftp susan

4. Change the ownership and permissions of the htdocs/ subdirectory of the XAMPP installation directory (typically, /opt/lampp) so that it is writable by the the new ftp group.

cd /opt/lampp chown root.ftp htdocs chmod 775 htdocs

5. Ensure that proFTPD is running in the XAMPP control panel.

You can now transfer files to the XAMPP server using the steps below:

1. Start an FTP client like winSCP or FileZilla and enter connection details as below.

If you’re connecting to the server from the same system, use "127.0.0.1" as the host address. If you’re connecting from a different system, use the network hostname or IP address of the XAMPP server.

Use "21" as the port.

Enter your Linux username and password as your FTP credentials.

Your FTP client should now connect to the server and enter the /opt/lampp/htdocs/ directory, which is the default Web server document root.

2. Transfer the file from your home directory to the server using normal FTP transfer conventions. If you’re using a graphical FTP client, you can usually drag and drop the file from one directory to the other. If you’re using a command-line FTP client, you can use the FTP PUT command.

Once the file is successfully transferred, you should be able to see it in action.

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

When you write a lambda expression, the argument list to the left of -> can be either a parenthesized argument list (possibly empty), or a single identifier without any parentheses. But in the second form, the identifier cannot be declared with a type name. Thus:

this.stops.stream().filter(Stop s-> s.getStation().getName().equals(name));

is incorrect syntax; but

this.stops.stream().filter((Stop s)-> s.getStation().getName().equals(name));

is correct. Or:

this.stops.stream().filter(s -> s.getStation().getName().equals(name));

is also correct if the compiler has enough information to figure out the types.

//Element[@attribute1="abc" and @attribute2="xyz" and .="Data"]

The reason why I add this answer is that I want to explain the relationship of . and text() .

The first thing is when using [], there are only two types of data:

1. [number] to select a node from node-set
2. [bool] to filter a node-set from node-set

In this case, the value is evaluated to boolean by function boolean(), and there is a rule:

Filters are always evaluated with respect to a context.

When you need to compare text() or . with a string "Data", it first uses string() function to transform those to string type, than gets a boolean result.

There are two important rule about string():

1. The string() function converts a node-set to a string by returning the string value of the first node in the node-set, which in some instances may yield unexpected results.

   text() is relative path that return a node-set contains all the text node of current node(context node), like ["Data"]. When it is evaluated by string(["Data"]), it will return the first node of node-set, so you get "Data" only when there is only one text node in the node-set.

2. If you want the string() function to concatenate all child text, you must then pass a single node instead of a node-set.

   For example, we get a node-set ['a', 'b'], you can pass there parent node to string(parent), this will return 'ab', and of cause string(.) in you case will return an concatenated string "Data".

Both way will get same result only when there is a text node.

Typically, boolean values that are used in branches immediately after they're calculated like this are never actually stored in variables. Instead, the compiler just branches directly off the condition codes that were set from the preceding comparison. For example,

int a = SomeFunction();
bool result = --a >= 0; // use subtraction as example computation
if ( result ) 
{
   foo(); 
}
else
{
   bar();
}
return;

Usually compiles to something like:

call .SomeFunction  ; calls to SomeFunction(), which stores its return value in eax
sub eax, 1 ; subtract 1 from eax and store in eax, set S (sign) flag if result is negative
jl ELSEBLOCK ; GOTO label "ELSEBLOCK" if S flag is set
call .foo ; this is the "if" black, call foo()
j FINISH ; GOTO FINISH; skip over the "else" block
ELSEBLOCK: ; label this location to the assembler
call .bar
FINISH: ; both paths end up here
ret ; return

Notice how the "bool" is never actually stored anywhere.

Using macros you can check if you're on Windows, Linux, Mac or Unix, and call the respective function depending on the current platform. Something as follows:

void clear(){
    #if defined(__linux__) || defined(__unix__) || defined(__APPLE__)
        system("clear");
    #endif

    #if defined(_WIN32) || defined(_WIN64)
        system("cls");
    #endif
}

Just put your two textviews host and port in an independant linearlayout horizontal and use android:layout_weight to make the percentage

Also OneToOneField is useful to be used as primary key to avoid key duplication. One may do not have implicit / explicit autofield

models.AutoField(primary_key=True)

but use OneToOneField as primary key instead (imagine UserProfile model for example):

user = models.OneToOneField(
    User, null=False, primary_key=True, verbose_name='Member profile')

A few updates for Flask 1.0 and above

the basic approach to hot re-loading is:

$ export FLASK_APP=my_application
$ export FLASK_ENV=development
$ flask run

• you should use FLASK_ENV=development (not FLASK_DEBUG=1)
• as a safety check, you can run flask run --debugger just to make sure it's turned on
• the Flask CLI will now automatically read things like FLASK_APP and FLASK_ENV if you have an .env file in the project root and have python-dotenv installed

bmleite has the correct answer about including the module.

If that is correct in your situation, you should also ensure that you are not redefining the modules in multiple files.

Remember:

angular.module('ModuleName', [])   // creates a module.

angular.module('ModuleName')       // gets you a pre-existing module.

So if you are extending a existing module, remember not to overwrite when trying to fetch it.

Also if you want selected field from table and aggregated then as array .

SELECT json_agg(json_build_object('data_a',a,
                                  'data_b',b,
))  from t;

The result will come .

 [{'data_a':1,'data_b':'value1'}
  {'data_a':2,'data_b':'value2'}]

If you make the image a background-image of a div in CSS, when that div is set to "display: none", the image will not load. When CSS is disabled, it still will not load, because, well, CSS is disabled.

Client side Upload Canceling

On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE, can be tampered with so always use server side validation.

<form method="post" enctype="multipart/form-data" action="upload.php">
    <input type="file" name="file" id="file" />
    <input type="submit" name="submit" value="Submit" />
</form>

<script>
document.forms[0].addEventListener('submit', function( evt ) {
    var file = document.getElementById('file').files[0];

    if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
        //Submit form        
    } else {
        //Prevent default and display error
        evt.preventDefault();
    }
}, false);
</script>

Server Side Upload Canceling

On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.

PHP Validation

On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES array to find out the upload size. (Docs on the contents of $_FILES can be found below the MAX_FILE_SIZE docs)

upload.php

<?php
if(isset($_FILES['file'])) {
    if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
        // File too big
    } else {
        // File within size restrictions
    }
}

Paste this code into the "On Key Down" Property of your form, also make sure you set "Key Preview" Property to "Yes".

If KeyCode = vbKeyEscape Then DoCmd.Close acForm, "YOUR FORM NAME"

just a FYI

string clean = Regex.Replace(q, @"[^a-zA-Z0-9\s]", string.Empty);

would actually be better like

string clean = Regex.Replace(q, @"[^\w\s]", string.Empty);

You need to consider the case where the user presses enter in the middle of the text, not just at the end. I'd suggest detecting the enter key in the keyup event, as suggested, and use a regular expression to ensure the value is as you require:

<textarea id="t" rows="4" cols="80"></textarea>
<script type="text/javascript">
    function formatTextArea(textArea) {
        textArea.value = textArea.value.replace(/(^|\r\n|\n)([^*]|$)/g, "$1*$2");
    }

    window.onload = function() {
        var textArea = document.getElementById("t");
        textArea.onkeyup = function(evt) {
            evt = evt || window.event;

            if (evt.keyCode == 13) {
                formatTextArea(this);
            }
        };
    };
</script>

Consider also .attr()

$("#roommate_but").attr("disabled", true); worked for me.

3. remove org.eclipse.core.resources
4. Start Eclipse
5. Do File->Import
6. General->Existing Projects into Workspace and import all the project from the workspace

Check Demo: https://stackblitz.com/edit/angular-6-checkbox?embed=1&file=src/app/app.component.html

  CheckBox: use change event to call the function and pass the event.

<label class="container">    
   <input type="checkbox" [(ngModel)]="theCheckbox"  data-md-icheck 
    (change)="toggleVisibility($event)"/>
      Checkbox is <span *ngIf="marked">checked</span><span

If you have already made some commits, you can do the following

git pull --rebase

This will place all your local commits on top of newly pulled changes.

BE VERY CAREFUL WITH THIS: this will probably overwrite all your present files with the files as they are at the head of the branch in the remote repo! If this happens and you didn't want it to you can UNDO THIS CHANGE with

git rebase --abort 

... naturally you have to do that before doing any new commits!

Open IIS manager, select Application Pools, select the application pool you are using, click on Advanced Settings in the right-hand menu. Under General, set "Enable 32-Bit Applications" to "True".

I got this working by following code

  getImgUrl(pet) {
    var images = require.context('../assets/', false, /\.png$/)
    return images('./' + pet + ".png")
  }

and in HTML:

<div class="col-lg-2" v-for="pic in pics">
   <img :src="getImgUrl(pic)" v-bind:alt="pic">
</div>

But not sure why my earlier approach did not work.

Actually most of the answers here doesn't really scale the image to the width of itself.

We need to have a width and height of auto on the img element itself so we can start with it's original size.

After that a container element can scale the image for us.

Simple HTML example:

<div style="position: relative;">
    <figure>
       <img src="[email protected]" />
    </figure>
</div>

And here are the CSS rules. I use an absolute container in this case:

figure {
    position: absolute;
    left: 0;
    top: 0;
    -webkit-transform: scale(0.5); 
    -moz-transform: scale(0.5);
    -ms-transform: scale(0.5); 
    -o-transform: scale(0.5);
    transform: scale(0.5);
    transform-origin: left;
} 

figure img {
    width: auto;
    height: auto;
}

You could tweak the image positioning with rules like transform: translate(0%, -50%);.

To write/save

%%writefile myfile.py

• write/save cell contents into myfile.py (use -a to append). Another alias: %%file myfile.py

To run

%run myfile.py

• run myfile.py and output results in the current cell

To load/import

%load myfile.py

• load "import" myfile.py into the current cell

For more magic and help

%lsmagic

• list all the other cool cell magic commands.

%COMMAND-NAME?

• for help on how to use a certain command. i.e. %run?

Note

Beside the cell magic commands, IPython notebook (now Jupyter notebook) is so cool that it allows you to use any unix command right from the cell (this is also equivalent to using the %%bash cell magic command).

To run a unix command from the cell, just precede your command with ! mark. for example:

• !python --version see your python version
• !python myfile.py run myfile.py and output results in the current cell, just like %run (see the difference between !python and %run in the comments below).

Also, see this nbviewer for further explanation with examples. Hope this helps.

I usually do it using add_all.

from app import session
from models import User

objects = [User(name="u1"), User(name="u2"), User(name="u3")]
session.add_all(objects)
session.commit()

I had a similar question to solve in a Udacity´s problems. Instead of a built-in function i coded:

def list_mean(n):

    summing = float(sum(n))
    count = float(len(n))
    if n == []:
        return False
    return float(summing/count)

Much more longer than usual but for a beginner its quite challenging.

select 'DROP TABLE ' + name from sysobjects
where type = 'U' and sysobjects.name like '%test%'

-- Test is the table name

Any mature enough SQL database should be able to execute that just as effectively as the equivalent JOIN. Use whatever is more readable to you.

Here we go:

var roleManager = new RoleManager<Microsoft.AspNet.Identity.EntityFramework.IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));


   if(!roleManager.RoleExists("ROLE NAME"))
   {
      var role = new Microsoft.AspNet.Identity.EntityFramework.IdentityRole();
      role.Name = "ROLE NAME";
      roleManager.Create(role);

    }

Try this to get type parameters for generic types:

public static string CSharpName(this Type type)
{
    var sb = new StringBuilder();
    var name = type.Name;
    if (!type.IsGenericType) return name;
    sb.Append(name.Substring(0, name.IndexOf('`')));
    sb.Append("<");
    sb.Append(string.Join(", ", type.GetGenericArguments()
                                    .Select(t => t.CSharpName())));
    sb.Append(">");
    return sb.ToString();
}

Maybe not the best solution (due to the recursion), but it works. Outputs look like:

Dictionary<String, Object>

To set a class completely, instead of adding one or removing one, use this:

$(this).attr("class","newclass");

Advantage of this is that you'll remove any class that might be set in there and reset it to how you like. At least this worked for me in one situation.

In case you are looking to include the font awesome library without having to do module imports and npm installs, put this in the head section of your React index.html page:

public/index.html (in head section)

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"/>

Then in your component (such as App.js) just use standard font awesome class convention. Just remember to use className instead of class:

<button className='btn'><i className='fa fa-home'></i></button>

I can't think of any reason why you would want to do that. If you just need to iterate over the dictionary, you can just do.

for key, elem in testDict.items():
    print key, elem

OR

for i in testDict:
     print i, testDict[i]

You're right. :before and :after pseudo content is not intended to work on replaced content like img and input elements. Adding a wrapping element and declare a font-family is one of the possibilities, as is using a background image. Or maybe a html5 placeholder text fits your needs:

<input name="username" placeholder="&#61447;">

Browsers that don’t support the placeholder attribute will simply ignore it.

UPDATE

The before content selector selects the input: input[type="text"]:before. You should select the wrapper: .wrapper:before. See http://jsfiddle.net/allcaps/gA4rx/ . I also added the placeholder suggestion where the wrapper is redundant.

.wrapper input[type="text"] {
    position: relative; 
}

input { font-family: 'FontAwesome'; } /* This is for the placeholder */

.wrapper:before {
    font-family: 'FontAwesome';
    color:red;
    position: relative;
    left: -5px;
    content: "\f007";
}

<p class="wrapper"><input placeholder="&#61447; Username"></p>

Fallback

Font Awesome uses the Unicode Private Use Area (PUA) to store icons. Other characters are not present and fall back to the browser default. That should be the same as any other input. If you define a font on input elements, then supply the same font as fallback for situations where us use an icon. Like this:

input { font-family: 'FontAwesome', YourFont; }

Just to understand better how tabindex elements works to complete accepted answer :

The tabindex global attribute is an integer indicating if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position. It can take several values:
  -a negative value means that the element should be focusable, but should not be reachable via sequential keyboard navigation;
  -0 means that the element should be focusable and reachable via sequential keyboard navigation, but its relative order is defined by the platform convention;
  -a positive value means should be focusable and reachable via sequential keyboard navigation; its relative order is defined by the value of the attribute: the sequential follow the increasing number of the tabindex. If several elements share the same tabindex, their relative order follows their relative position in the document.

use this:

    Notification mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_music)
                    .setContentTitle(songName).build();


    mBuilder.contentIntent=  PendingIntent.getActivity(this, 0,
            new Intent(this, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);

contentIntent will take care of openning activity when notification clicked

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

Download Androidx86 from this This is an iso file, so you'd
need something like VMWare or VirtualBox to run it When creating the virtual machine, you need to set the type of guest OS as Linux instead of Other.

After creating the virtual machine set the network adapter to 'Bridged'. · Start the VM and select 'Live CD VESA' at boot.

Now you need to find out the IP of this VM. Go to terminal in VM (use Alt+F1 & Alt+F7 to toggle) and use the netcfg command to find this.

Now you need open a command prompt and go to your android install folder (on host). This is usually C:\Program Files\Android\android-sdk\platform-tools>.

Type adb connect IP_ADDRESS. There done! Now you need to add Bluetooth. Plug in your USB Bluetooth dongle/Bluetooth device.

In VirtualBox screen, go to Devices>USB devices. Select your dongle.

Done! now your Android VM has Bluetooth. Try powering on Bluetooth and discovering/paring with other devices.

Now all that remains is to go to Eclipse and run your program. The Android AVD manager should show the VM as a device on the list.

Alternatively, Under settings of the virtual machine, Goto serialports -> Port 1 check Enable serial port select a port number then select port mode as disconnected click ok. now, start virtual machine. Under Devices -> USB Devices -> you can find your laptop bluetooth listed. You can simply check the option and start testing the android bluetooth application .

Source

You cannot push anything that hasn't been committed yet. The order of operations is:

1. Make your change.
2. git add - this stages your changes for committing
3. git commit - this commits your staged changes locally
4. git push - this pushes your committed changes to a remote

If you push without committing, nothing gets pushed. If you commit without adding, nothing gets committed. If you add without committing, nothing at all happens, git merely remembers that the changes you added should be considered for the following commit.

The message you're seeing (your branch is ahead by 1 commit) means that your local repository has one commit that hasn't been pushed yet.

In other words: add and commit are local operations, push, pull and fetch are operations that interact with a remote.

Since there seems to be an official source control workflow in place where you work, you should ask internally how this should be handled.

Below is the way we can do Multiple projection to perform Distinct

    package org.hibernate.criterion;

import org.hibernate.Criteria;
import org.hibernate.Hibernate;
import org.hibernate.HibernateException;
import org.hibernate.type.Type;

/**
* A count for style :  count (distinct (a || b || c))
*/
public class MultipleCountProjection extends AggregateProjection {

   private boolean distinct;

   protected MultipleCountProjection(String prop) {
      super("count", prop);
   }

   public String toString() {
      if(distinct) {
         return "distinct " + super.toString();
      } else {
         return super.toString();
      }
   }

   public Type[] getTypes(Criteria criteria, CriteriaQuery criteriaQuery) 
   throws HibernateException {
      return new Type[] { Hibernate.INTEGER };
   }

   public String toSqlString(Criteria criteria, int position, CriteriaQuery criteriaQuery) 
   throws HibernateException {
      StringBuffer buf = new StringBuffer();
      buf.append("count(");
      if (distinct) buf.append("distinct ");
        String[] properties = propertyName.split(";");
        for (int i = 0; i < properties.length; i++) {
           buf.append( criteriaQuery.getColumn(criteria, properties[i]) );
             if(i != properties.length - 1) 
                buf.append(" || ");
        }
        buf.append(") as y");
        buf.append(position);
        buf.append('_');
        return buf.toString();
   }

   public MultipleCountProjection setDistinct() {
      distinct = true;
      return this;
   }

}

ExtraProjections.java

package org.hibernate.criterion; 

public final class ExtraProjections
{ 
    public static MultipleCountProjection countMultipleDistinct(String propertyNames) {
        return new MultipleCountProjection(propertyNames).setDistinct();
    }
}

Sample Usage:

String propertyNames = "titleName;titleDescr;titleVersion"

criteria countCriteria = ....

countCriteria.setProjection(ExtraProjections.countMultipleDistinct(propertyNames);

Follow these steps to create CSR (Code Signing Identity):

1. On your Mac, go to the folder 'Applications' ? 'Utilities' and open 'Keychain Access.'

   

2. Go to 'Keychain Access' ? Certificate Assistant ? Request a Certificate from a Certificate Authority. ?

   

3. Fill out the information in the Certificate Information window as specified below and click "Continue."
   • In the User Email Address field, enter the email address to identify with this certificate
   • In the Common Name field, enter your name
   • In the Request group, click the "Saved to disk" option ?

   

4. Save the file to your hard drive.

   

Use this CSR (.certSigningRequest) file to create project/application certificates and profiles, in Apple developer account.

A lot of the code here was very helpful, but I cleaned it up for my purposes and added some tests. Here's what I ended up with:

using System;
using System.Linq;
using System.Net;
using System.Web;

public class RequestHelpers
{
    public static string GetClientIpAddress(HttpRequestBase request)
    {
        try
        {
            var userHostAddress = request.UserHostAddress;

            // Attempt to parse.  If it fails, we catch below and return "0.0.0.0"
            // Could use TryParse instead, but I wanted to catch all exceptions
            IPAddress.Parse(userHostAddress);

            var xForwardedFor = request.ServerVariables["X_FORWARDED_FOR"];

            if (string.IsNullOrEmpty(xForwardedFor))
                return userHostAddress;

            // Get a list of public ip addresses in the X_FORWARDED_FOR variable
            var publicForwardingIps = xForwardedFor.Split(',').Where(ip => !IsPrivateIpAddress(ip)).ToList();

            // If we found any, return the last one, otherwise return the user host address
            return publicForwardingIps.Any() ? publicForwardingIps.Last() : userHostAddress;
        }
        catch (Exception)
        {
            // Always return all zeroes for any failure (my calling code expects it)
            return "0.0.0.0";
        }
    }

    private static bool IsPrivateIpAddress(string ipAddress)
    {
        // http://en.wikipedia.org/wiki/Private_network
        // Private IP Addresses are: 
        //  24-bit block: 10.0.0.0 through 10.255.255.255
        //  20-bit block: 172.16.0.0 through 172.31.255.255
        //  16-bit block: 192.168.0.0 through 192.168.255.255
        //  Link-local addresses: 169.254.0.0 through 169.254.255.255 (http://en.wikipedia.org/wiki/Link-local_address)

        var ip = IPAddress.Parse(ipAddress);
        var octets = ip.GetAddressBytes();

        var is24BitBlock = octets[0] == 10;
        if (is24BitBlock) return true; // Return to prevent further processing

        var is20BitBlock = octets[0] == 172 && octets[1] >= 16 && octets[1] <= 31;
        if (is20BitBlock) return true; // Return to prevent further processing

        var is16BitBlock = octets[0] == 192 && octets[1] == 168;
        if (is16BitBlock) return true; // Return to prevent further processing

        var isLinkLocalAddress = octets[0] == 169 && octets[1] == 254;
        return isLinkLocalAddress;
    }
}

(Following is a late but complete answer)

FileReader methods support

FileReader.readAsBinaryString() is deprecated. Don't use it! It's no longer in the W3C File API working draft:

void abort();
void readAsArrayBuffer(Blob blob);
void readAsText(Blob blob, optional DOMString encoding);
void readAsDataURL(Blob blob);

NB: Note that File is a kind of extended Blob structure.

Mozilla still implements readAsBinaryString() and describes it in MDN FileApi documentation:

void abort();
void readAsArrayBuffer(in Blob blob); Requires Gecko 7.0
void readAsBinaryString(in Blob blob);
void readAsDataURL(in Blob file);
void readAsText(in Blob blob, [optional] in DOMString encoding);

The reason behind readAsBinaryString() deprecation is in my opinion the following: the standard for JavaScript strings are DOMString which only accept UTF-8 characters, NOT random binary data. So don't use readAsBinaryString(), that's not safe and ECMAScript-compliant at all.

We know that JavaScript strings are not supposed to store binary data but Mozilla in some sort can. That's dangerous in my opinion. Blob and typed arrays (ArrayBuffer and the not-yet-implemented but not necessary StringView) were invented for one purpose: allow the use of pure binary data, without UTF-8 strings restrictions.

XMLHttpRequest upload support

XMLHttpRequest.send() has the following invocations options:

void send();
void send(ArrayBuffer data);
void send(Blob data);
void send(Document data);
void send(DOMString? data);
void send(FormData data);

XMLHttpRequest.sendAsBinary() has the following invocations options:

void sendAsBinary(   in DOMString body );

sendAsBinary() is NOT a standard and may not be supported in Chrome.

Solutions

So you have several options:

1. send() the FileReader.result of FileReader.readAsArrayBuffer ( fileObject ). It is more complicated to manipulate (you'll have to make a separate send() for it) but it's the RECOMMENDED APPROACH.
2. send() the FileReader.result of FileReader.readAsDataURL( fileObject ). It generates useless overhead and compression latency, requires a decompression step on the server-side BUT it's easy to manipulate as a string in Javascript.
3. Being non-standard and sendAsBinary() the FileReader.result of FileReader.readAsBinaryString( fileObject )

MDN states that:

The best way to send binary content (like in files upload) is using ArrayBuffers or Blobs in conjuncton with the send() method. However, if you want to send a stringifiable raw data, use the sendAsBinary() method instead, or the StringView (Non native) typed arrays superclass.

You need to use the command echo $PATH to display the PATH variable or you can just execute set or env to display all of your environment variables.

By typing $PATH you tried to run your PATH variable contents as a command name.

Bash displayed the contents of your path any way. Based on your output the following directories will be searched in the following order:

/usr/local/share/npm/bin
/Library/Frameworks/Python.framework/Versions/2.7/bin
/usr/local/bin
/usr/local/sbin
~/bin
/Library/Frameworks/Python.framework/Versions/Current/bin
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
/opt/X11/bin
/usr/local/git/bin

To me this list appears to be complete.

if (/(^|;)\s*visited=/.test(document.cookie)) {
    alert("Hello again!");
} else {
    document.cookie = "visited=true; max-age=" + 60 * 60 * 24 * 10; // 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day, and 10 days.
    alert("This is your first time!");
}

is one way to do it. Note that document.cookie is a magic property, so you don't have to worry about overwriting anything, either.

There are also more convenient libraries to work with cookies, and if you don’t need the information you’re storing sent to the server on every request, HTML5’s localStorage and friends are convenient and useful.

If you are saying that your problem is how to left align the form labels, see if this helps:
http://jsfiddle.net/panchroma/8gYPQ/

Try changing the text-align left / right in the CSS

.form-horizontal .control-label{
    /* text-align:right; */
    text-align:left;
    background-color:#ffa;
}

Good luck!

Try with regex \d:

$words = preg_replace('/\d/', '', $words );

\d is an equivalent for [0-9] which is an equivalent for numbers range from 0 to 9.

The most useful thing you can do here is display/i $pc, before using stepi as already suggested in R Samuel Klatchko's answer. This tells gdb to disassemble the current instruction just before printing the prompt each time; then you can just keep hitting Enter to repeat the stepi command.

(See my answer to another question for more detail - the context of that question was different, but the principle is the same.)

Try using the code after you active the sheet:

Dim J as integer
J = ActiveSheet.UsedRange.SpecialCells(xlCellTypeLastCell).Row

If you use Cells.SpecialCells(xlCellTypeLastCell).Row only, the problem will be that the xlCellTypeLastCell information will not be updated unless one do a "Save file" action. But use UsedRange will always update the information in realtime.

It's a bit kludgey, but in your click event, use SendKeys.Send( "{HOME}+{END}" );.

$("#text").val(function(i,v) { 
   return v.replace(".", ":"); 
});

MongoDB has a simple web based administrative port at 28017 by default.

There is no HTTP access at the default port of 27017 (which is what the error message is trying to suggest). The default port is used for native driver access, not HTTP traffic.

To access MongoDB, you'll need to use a driver like the MongoDB native driver for NodeJS. You won't "POST" to MongoDB directly (but you might create a RESTful API using express which uses the native drivers). Instead, you'll use a wrapper library that makes accessing MongoDB convenient. You might also consider using Mongoose (which uses the native driver) which adds an ORM-like model for MongoDB in NodeJS.

If you can't get to the web interface, it may be disabled. Normally, I wouldn't expect that you'd need it for doing development unless you're checking logs and such.

How about using this instead ?

final DisplayMetrics displayMetrics=getResources().getDisplayMetrics();
final float screenWidthInDp=displayMetrics.widthPixels/displayMetrics.density;
final float screenHeightInDp=displayMetrics.heightPixels/displayMetrics.density;

As stated in this blog post it seems possible to use mod_security to implement a rate limit per second.

The configuration is something like this:

SecRuleEngine On

  SecAction initcol:ip=%{REMOTE_ADDR},pass,nolog
  SecAction "phase:5,deprecatevar:ip.somepathcounter=1/1,pass,nolog"
  SecRule IP:SOMEPATHCOUNTER "@gt 60" "phase:2,pause:300,deny,status:509,setenv:RATELIMITED,skip:1,nolog"
  SecAction "phase:2,pass,setvar:ip.somepathcounter=+1,nolog"
  Header always set Retry-After "10" env=RATELIMITED
</LocationMatch>

ErrorDocument 509 "Rate Limit Exceeded"

Here is a practical addition to the answers of PierreBdR and Moe:

• For Python >= 2.6 and new-style classes, dir() seems to be enough.

• For old-style classes, we can at least do what a standard module does to support tab completion: in addition to dir(), look for __class__, and then to go for its __bases__:

  # code borrowed from the rlcompleter module
  # tested under Python 2.6 ( sys.version = '2.6.5 (r265:79063, Apr 16 2010, 13:09:56) \n[GCC 4.4.3]' )
  
  # or: from rlcompleter import get_class_members
  def get_class_members(klass):
      ret = dir(klass)
      if hasattr(klass,'__bases__'):
          for base in klass.__bases__:
              ret = ret + get_class_members(base)
      return ret
  
  
  def uniq( seq ): 
      """ the 'set()' way ( use dict when there's no set ) """
      return list(set(seq))
  
  
  def get_object_attrs( obj ):
      # code borrowed from the rlcompleter module ( see the code for Completer::attr_matches() )
      ret = dir( obj )
      ## if "__builtins__" in ret:
      ##    ret.remove("__builtins__")
  
      if hasattr( obj, '__class__'):
          ret.append('__class__')
          ret.extend( get_class_members(obj.__class__) )
  
          ret = uniq( ret )
  
      return ret
  

(Test code and output are deleted for brevity, but basically for new-style objects we seem to have the same results for get_object_attrs() as for dir(), and for old-style classes the main addition to the dir() output seem to be the __class__ attribute.)

I hope below solution will work for you all as I was having the same problem with my websites...

For : $json = json_decode(file_get_contents('http://...'));

Replace with below query

$Details= unserialize(file_get_contents('http://......'));

The same syntax works for Ms SQL server using podbc also.

import pyodbc
import pandas.io.sql as psql

cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=servername;DATABASE=mydb;UID=username;PWD=password') 
cursor = cnxn.cursor()
sql = ("""select * from mytable""")

df = psql.frame_query(sql, cnxn)
cnxn.close()

Great article i found what worked best for me was to add a % to the size

.wrap {
margin-top:5%;
margin-bottom:5%;
height:100%;
display:block;}

1 unless file exists will rewrite to index.php

Add the following to your location ~ \.php$

try_files = $uri @missing;

this will first try to serve the file and if it's not found it will move to the @missing part. so also add the following to your config (outside the location block), this will redirect to your index page

location @missing {
    rewrite ^ $scheme://$host/index.php permanent;
}

2 on the urls you never see the file extension (.php)

to remove the php extension read the following: http://www.nullis.net/weblog/2011/05/nginx-rewrite-remove-file-extension/

and the example configuration from the link:

location / {
    set $page_to_view "/index.php";
    try_files $uri $uri/ @rewrites;
    root   /var/www/site;
    index  index.php index.html index.htm;
}

location ~ \.php$ {
    include /etc/nginx/fastcgi_params;
    fastcgi_pass  127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME /var/www/site$page_to_view;
}

# rewrites
location @rewrites {
    if ($uri ~* ^/([a-z]+)$) {
        set $page_to_view "/$1.php";
        rewrite ^/([a-z]+)$ /$1.php last;
    }
}

Or do the following:

...

  Integer[] integerArray = new Integer[integerList.size()];
  integerList.toArray(integerArray);

  return integerArray;

}

Simplest solution

Use numpy.dot or a.dot(b). See the documentation here.

>>> a = np.array([[ 5, 1 ,3], 
                  [ 1, 1 ,1], 
                  [ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])

This occurs because numpy arrays are not matrices, and the standard operations *, +, -, / work element-wise on arrays. Instead, you could try using numpy.matrix, and * will be treated like matrix multiplication.

Other Solutions

Also know there are other options:

• As noted below, if using python3.5+ the @ operator works as you'd expect:

  >>> print(a @ b)
  array([16, 6, 8])
  

• If you want overkill, you can use numpy.einsum. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.

  >>> np.einsum('ji,i->j', a, b)
  array([16, 6, 8])
  

• As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul, which works like numpy.dot with two major exceptions: no scalar multiplication but it works with stacks of matrices.

  >>> np.matmul(a, b)
  array([16, 6, 8])
  

• numpy.inner functions the same way as numpy.dot for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).

  >>> np.inner(a, b)
  array([16, 6, 8])
  
  # Beware using for matrix-matrix multiplication though!
  >>> b = a.T
  >>> np.dot(a, b)
  array([[35,  9, 10],
         [ 9,  3,  4],
         [10,  4,  6]])
  >>> np.inner(a, b) 
  array([[29, 12, 19],
         [ 7,  4,  5],
         [ 8,  5,  6]])
  

Rarer options for edge cases

• If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot with the optional argument axes=1:

  >>> np.tensordot(a, b, axes=1)
  array([16,  6,  8])
  

• Don't use numpy.vdot if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m vs n).

In addition to Alex B's answer.

It is even required to use the setUp method to instantiate resources in a certain state. Doing this in the constructor is not only a matter of timings, but because of the way JUnit runs the tests, each test state would be erased after running one.

JUnit first creates instances of the testClass for each test method and starts running the tests after each instance is created. Before running the test method, its setup method is ran, in which some state can be prepared.

If the database state would be created in the constructor, all instances would instantiate the db state right after each other, before running each tests. As of the second test, tests would run with a dirty state.

JUnits lifecycle:

1. Create a different testclass instance for each test method
2. Repeat for each testclass instance: call setup + call the testmethod

With some loggings in a test with two test methods you get: (number is the hashcode)

• Creating new instance: 5718203
• Creating new instance: 5947506
• Setup: 5718203
• TestOne: 5718203
• Setup: 5947506
• TestTwo: 5947506

You can use something like:

add_custom_target(clean-cmake-files
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

// clean-all.cmake
set(cmake_generated ${CMAKE_BINARY_DIR}/CMakeCache.txt
                    ${CMAKE_BINARY_DIR}/cmake_install.cmake
                    ${CMAKE_BINARY_DIR}/Makefile
                    ${CMAKE_BINARY_DIR}/CMakeFiles
)

foreach(file ${cmake_generated})

  if (EXISTS ${file})
     file(REMOVE_RECURSE ${file})
  endif()

endforeach(file)

I usually create a "make clean-all" command adding a call to "make clean" to the previous example:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

Don't try to add the "clean" target as a dependence:

add_custom_target(clean-all
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
   DEPENDS clean
)

Because "clean" isn't a real target in CMake and this doesn't work.

Moreover, you should not use this "clean-cmake-files" as dependence of anything:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   DEPENDS clean-cmake-files
)

Because, if you do that, all CMake files will be erased before clean-all is complete, and make will throw you an error searching "CMakeFiles/clean-all.dir/build.make". In consequence, you can not use the clean-all command before "anything" in any context:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

That doesn't work either.

In my case, I tried to first use port 88 instead, and even then the httpd won't start.

I used the below command, i.e. modify instead of add, as suggested by one of users, and was able to run httpd.

semanage port -a -t http_port_t -p tcp 88

Well, @Jon Skeet, if we're not worried about getting any more granular than days (and still rolling days into larger units rather than having a total day count), as per the OP, it's really not that difficult in C#. What makes date math so difficult is that the number of units in each composite unit often changes. Imagine if every 3rd gallon of gas was only 3 quarts, but each 12th was 7, except on Fridays, when...

Luckily, dates are just a long ride through the greatest integer function. These crazy exceptions are maddening, unless you've gone all the way through the wackily-comprised unit, when it's not a big deal any more. If you're born on 12/25/1900, you're still EXACTLY 100 on 12/25/2000, regardless of the leap years or seconds or daylight savings periods you've been through. As soon as you've slogged through the percentages that make up the last composite unit, you're back to unity. You've added one, and get to start over.

Which is just to say that if you're doing years to months to days, the only strangely comprised unit is the month (of days). If you need to borrow from the month value to handle a place where you're subtracting more days than you've got, you just need to know the number of days in the previous month. No other outliers matter.

And C# gives that to you in System.DateTime.DaysInMonth(intYear, intMonth).

(If your Now month is smaller than your Then month, there's no issue. Every year has 12 months.)

And the same deal if we go more granular... you just need to know how many (small units) are in the last (composite unit). Once you're past, you get another integer value more of (composite unit). Then subtract how many small units you missed starting where you did Then and add back how many of those you went past the composite unit break-off with your Now.

So here's what I've got from my first cut at subtracting two dates. It might work. Hopefully useful.

(EDIT: Changed NewMonth > OldMonth check to NewMonth >= OldMonth, as we don't need to borrow one if the Months are the same (ditto for days). That is, Nov 11 2011 minus Nov 9 2010 was giving -1 year, 12 months, 2 days (ie, 2 days, but the royal we borrowed when royalty didn't need to.)

(EDIT: Had to check for Month = Month when we needed to borrow days to subtract a dteThen.Day from dteNow.Day & dteNow.Day < dteThen.Day, as we had to subtract a year to get 11 months and the extra days. Okay, so there are a few outliers. ;^D I think I'm close now.)

    }
    else
    {   // else we need to substract one from the month diff (borrow the one)
        // and days get wacky.

        // Watch for the outlier of Month = Month with DayNow < DayThen, as then we've 
        // got to subtract one from the year diff to borrow a month and have enough

            // the LAST month into subtractable days
            // Stay with me -- because we borrowed days from the year, not the month,
            // this is much different than what appears to be a similar calculation below.
            // We know we're a full intDiffInYears years apart PLUS eleven months.
            // Now we need to know how many days occurred before dteThen was done with 
            // dteThen.Month.  Then we add the number of days we've "earned" in the current
            // month.  
            //
            // So 12/25/2009 to 12/1/2011 gives us

            // 1 year 11 months - 12 months = 11 months difference
            // (days from 12/25 to the End Of Month) + (Begin of Month to 12/1) = 
            //                (31-25)                +       (0+1)              =

            //
            // 12/25/2009 to 12/1/2011 is 1 year, 11 months, 7 days apart.  QED.

            // full months between the two dates.  But then we've got to go from 10/8 to
            // 11/07.  So that's the previous month's (October) number of days (31) minus

The suggestion to override new/initialize is probably incomplete. Rails will (frequently) call allocate for ActiveRecord objects, and calls to allocate won't result in calls to initialize.

If you're talking about ActiveRecord objects, take a look at overriding after_initialize.

These blog posts (not mine) are useful:

Default values Default constructors not called

[Edit: SFEley points out that Rails actually does look at the default in the database when it instantiates a new object in memory - I hadn't realized that.]

Server version: Apache/2.4.29 (Ubuntu)

After long search on the web and in the official documentation of apache, the only solution that worked for me came from /usr/share/doc/apache2/README.Debian.gz

To enable SSL, type (as user root):

    a2ensite default-ssl
    a2enmod ssl

In the file /etc/apache2/sites-available/000-default.conf add the

Redirect "/" "https://sub.domain.com/"

<VirtualHost *:80>

    #ServerName www.example.com
    DocumentRoot /var/www/owncloud
    Redirect "/" "https://sub.domain.com/"

That's it.

P.S: If you want to read the manual without extracting:

gunzip -cd /usr/share/doc/apache2/README.Debian.gz

from sys import exit
exit()

As a parameter you can pass an exit code, which will be returned to OS. Default is 0.

CSS really doesn't have the ability to modify an object in the same manner as JavaScript, so in short - no.

You can't do it at all, let alone quickly. Arrays in Java are fixed size. Two things you could do are:

1. Shift every element up one, then set the last element to null.
2. Create a new array, then copy it.

You can use System.arraycopy for either of these. Both of these are O(n), since they copy all but 1 element.

If you will be removing the first element often, consider using LinkedList instead. You can use LinkedList.remove, which is from the Queue interface, for convenience. With LinkedList, removing the first element is O(1). In fact, removing any element is O(1) once you have a ListIterator to that position. However, accessing an arbitrary element by index is O(n).

Using Blob as a source for an img:

template:

<img [src]="url">

component:

 public url : SafeResourceUrl;

 constructor(private http: HttpClient, private sanitizer: DomSanitizer) {
   this.getImage('/api/image.jpg').subscribe(x => this.url = x)
 }

 public getImage(url: string): Observable<SafeResourceUrl> {
   return this.http
     .get(url, { responseType: 'blob' })
     .pipe(
       map(x => {
         const urlToBlob = window.URL.createObjectURL(x) // get a URL for the blob
         return this.sanitizer.bypassSecurityTrustResourceUrl(urlToBlob); // tell Anuglar to trust this value
       }),
     );
 }

Further reference about trusting save values

You can do this with a single statement - assuming you are calling it from a JDBC-like connector with in/out parameters functionality:

insert into batch(batchid, batchname) 
values (batch_seq.nextval, 'new batch')
returning batchid into :l_batchid;

or, as a pl-sql script:

variable l_batchid number;

insert into batch(batchid, batchname) 
values (batch_seq.nextval, 'new batch')
returning batchid into :l_batchid;

select :l_batchid from dual;

Execute:

nc -v -z <git-repository> <port>

Your output should look like:

"Connection to <git-repository> <port> port [tcp/*] succeeded!"

If you get:

connect to <git-repository> <port> (tcp) failed: Connection timed out

You need to edit your ~/.ssh/config file. Add something like the following:

Host example.com
Port 1234

I don't think you can mount a Linux folder as a network drive under windows having only access to ssh. I can suggest you to use WinSCP that allows you to transfer file through ssh and it's free.

EDIT: well, sorry. Vinko posted before me and now i've learned a new thing :)

You can simply download the library which you want to include and copy it to libs folder of your project. Then select that file (in my case it was android-support-v4 library) right click on it and select "Add as Library"

New escape string in PowerShell V3, quoted from New V3 Language Features:

Easier Reuse of Command Lines From Cmd.exe

The web is full of command lines written for Cmd.exe. These commands lines work often enough in PowerShell, but when they include certain characters, for example, a semicolon (;), a dollar sign ($), or curly braces, you have to make some changes, probably adding some quotes. This seemed to be the source of many minor headaches.

To help address this scenario, we added a new way to “escape” the parsing of command lines. If you use a magic parameter --%, we stop our normal parsing of your command line and switch to something much simpler. We don’t match quotes. We don’t stop at semicolon. We don’t expand PowerShell variables. We do expand environment variables if you use Cmd.exe syntax (e.g. %TEMP%). Other than that, the arguments up to the end of the line (or pipe, if you are piping) are passed as is. Here is an example:

PS> echoargs.exe --% %USERNAME%,this=$something{weird}
Arg 0 is <jason,this=$something{weird}>

Yacoby's answer inspires me to write an adaptor for encapsulating the functor boilerplate.

template< class T, bool (*comp)( T const &, T const & ) >
class set_funcomp {
    struct ftor {
        bool operator()( T const &l, T const &r )
            { return comp( l, r ); }
    };
public:
    typedef std::set< T, ftor > t;
};

// usage

bool my_comparison( foo const &l, foo const &r );
set_funcomp< foo, my_comparison >::t boo; // just the way you want it!

Wow, I think that was worth the trouble!

You can read it from the input stream:

public ActionResult ManagePhotos(ManagePhotos model)
{
    if (ModelState.IsValid)
    {
        byte[] image = new byte[model.File.ContentLength];
        model.File.InputStream.Read(image, 0, image.Length); 

        // TODO: Do something with the byte array here
    }
    ...
}

And if you intend to directly save the file to the disk you could use the model.File.SaveAs method. You might find the following blog post useful.

ImageView Button = (ImageView)findViewById(R.id.button);

Button.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        Uri uri = Uri.parse("http://google.com/");

        Intent intent = new Intent(Intent.ACTION_VIEW, uri);
        startActivity(intent);
    }
});

Container widths will drop down to 940 pixels for viewports less than 992 pixels. If you really don’t want containers larger than 940 pixels wide, then go to the Bootstrap customize page, and set @container-lg-desktop to either @container-desktop or hard-coded 940px.

Use this simple function for date comparison

-(BOOL)dateComparision:(NSDate*)date1 andDate2:(NSDate*)date2{

BOOL isTokonValid;

if ([date1 compare:date2] == NSOrderedDescending) {
    NSLog(@"date1 is later than date2");
    isTokonValid = YES;
} else if ([date1 compare:date2] == NSOrderedAscending) {
    NSLog(@"date1 is earlier than date2");
    isTokonValid = NO;
} else {
    isTokonValid = NO;
    NSLog(@"dates are the same");
}

return isTokonValid;}

For newer version of python:

exec(open(filename).read())

The other answers are not working for me - they may be outdated. This is what I used as my solution for auto setting an attribute:

/**
 * The "booting" method of the model.
 *
 * @return void
 */
protected static function boot()
{
    parent::boot();

    // auto-sets values on creation
    static::creating(function ($query) {
        $query->is_voicemail = $query->is_voicemail ?? true;
    });
}

This is the 2nd of two answers.

If you want to just strip all namespaces arbitrarily from a document during serialization, you can do this by implementing your own XmlWriter.

The easiest way is to derive from XmlTextWriter and override the StartElement method that emits namespaces. The StartElement method is invoked by the XmlSerializer when emitting any elements, including the root. By overriding the namespace for each element, and replacing it with the empty string, you've stripped the namespaces from the output.

public class NoNamespaceXmlWriter : XmlTextWriter
{
    //Provide as many contructors as you need
    public NoNamespaceXmlWriter(System.IO.TextWriter output)
        : base(output) { Formatting= System.Xml.Formatting.Indented;}

    public override void WriteStartDocument () { }

    public override void WriteStartElement(string prefix, string localName, string ns)
    {
        base.WriteStartElement("", localName, "");
    }
}

Suppose this is the type:

// explicitly specify a namespace for this type,
// to be used during XML serialization.
[XmlRoot(Namespace="urn:Abracadabra")]
public class MyTypeWithNamespaces
{
    // private fields backing the properties
    private int _Epoch;
    private string _Label;

    // explicitly define a distinct namespace for this element
    [XmlElement(Namespace="urn:Whoohoo")]
    public string Label
    {
        set {  _Label= value; } 
        get { return _Label; } 
    }

    // this property will be implicitly serialized to XML using the
    // member name for the element name, and inheriting the namespace from
    // the type.
    public int Epoch
    {
        set {  _Epoch= value; } 
        get { return _Epoch; } 
    }
}

Here's how you would use such a thing during serialization:

        var o2= new MyTypeWithNamespaces { ..intializers.. };
        var builder = new System.Text.StringBuilder();
        using ( XmlWriter writer = new NoNamespaceXmlWriter(new System.IO.StringWriter(builder)))
        {
            s2.Serialize(writer, o2, ns2);
        }            
        Console.WriteLine("{0}",builder.ToString());

The XmlTextWriter is sort of broken, though. According to the reference doc, when it writes it does not check for the following:

• Invalid characters in attribute and element names.

• Unicode characters that do not fit the specified encoding. If the Unicode characters do not fit the specified encoding, the XmlTextWriter does not escape the Unicode characters into character entities.

• Duplicate attributes.

• Characters in the DOCTYPE public identifier or system identifier.

These problems with XmlTextWriter have been around since v1.1 of the .NET Framework, and they will remain, for backward compatibility. If you have no concerns about those problems, then by all means use the XmlTextWriter. But most people would like a bit more reliability.

To get that, while still suppressing namespaces during serialization, instead of deriving from XmlTextWriter, define a concrete implementation of the abstract XmlWriter and its 24 methods.

An example is here:

public class XmlWriterWrapper : XmlWriter
{
    protected XmlWriter writer;

    public XmlWriterWrapper(XmlWriter baseWriter)
    {
        this.Writer = baseWriter;
    }

    public override void Close()
    {
        this.writer.Close();
    }

    protected override void Dispose(bool disposing)
    {
        ((IDisposable) this.writer).Dispose();
    }

    public override void Flush()
    {
        this.writer.Flush();
    }

    public override string LookupPrefix(string ns)
    {
        return this.writer.LookupPrefix(ns);
    }

    public override void WriteBase64(byte[] buffer, int index, int count)
    {
        this.writer.WriteBase64(buffer, index, count);
    }

    public override void WriteCData(string text)
    {
        this.writer.WriteCData(text);
    }

    public override void WriteCharEntity(char ch)
    {
        this.writer.WriteCharEntity(ch);
    }

    public override void WriteChars(char[] buffer, int index, int count)
    {
        this.writer.WriteChars(buffer, index, count);
    }

    public override void WriteComment(string text)
    {
        this.writer.WriteComment(text);
    }

    public override void WriteDocType(string name, string pubid, string sysid, string subset)
    {
        this.writer.WriteDocType(name, pubid, sysid, subset);
    }

    public override void WriteEndAttribute()
    {
        this.writer.WriteEndAttribute();
    }

    public override void WriteEndDocument()
    {
        this.writer.WriteEndDocument();
    }

    public override void WriteEndElement()
    {
        this.writer.WriteEndElement();
    }

    public override void WriteEntityRef(string name)
    {

Then, provide a derived class that overrides the StartElement method, as before:

public class NamespaceSupressingXmlWriter : XmlWriterWrapper
{
    //Provide as many contructors as you need
    public NamespaceSupressingXmlWriter(System.IO.TextWriter output)
        : base(XmlWriter.Create(output)) { }

    public NamespaceSupressingXmlWriter(XmlWriter output)
        : base(XmlWriter.Create(output)) { }

    public override void WriteStartElement(string prefix, string localName, string ns)
    {
        base.WriteStartElement("", localName, "");
    }
}

And then use this writer like so:

        var o2= new MyTypeWithNamespaces { ..intializers.. };
        var builder = new System.Text.StringBuilder();
        var settings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent= true };
        using ( XmlWriter innerWriter = XmlWriter.Create(builder, settings))
            using ( XmlWriter writer = new NamespaceSupressingXmlWriter(innerWriter))
            {
                s2.Serialize(writer, o2, ns2);
            }            
        Console.WriteLine("{0}",builder.ToString());

So far, the accepted answer has worked best for me. However, my concern has always been that there is a likely scenario where I might refactor the notebooks directory into subdirectories, requiring to change the module_path in every notebook. I decided to add a python file within each notebook directory to import the required modules.

Thus, having the following project structure:

project
|__notebooks
   |__explore
      |__ notebook1.ipynb
      |__ notebook2.ipynb
      |__ project_path.py
   |__ explain
       |__notebook1.ipynb
       |__project_path.py
|__lib
   |__ __init__.py
   |__ module.py

I added the file project_path.py in each notebook subdirectory (notebooks/explore and notebooks/explain). This file contains the code for relative imports (from @metakermit):

import sys
import os

module_path = os.path.abspath(os.path.join(os.pardir, os.pardir))
if module_path not in sys.path:
    sys.path.append(module_path)

This way, I just need to do relative imports within the project_path.py file, and not in the notebooks. The notebooks files would then just need to import project_path before importing lib. For example in 0.0-notebook.ipynb:

import project_path
import lib

The caveat here is that reversing the imports would not work. THIS DOES NOT WORK:

import lib
import project_path

Thus care must be taken during imports.

To resolving this problem.I just create a new folder and put some new files.Then use these commond.

* git add .
* git commit 
* git remote add master `your address`

then it tells me to login in. To input your username and password. after that

git pull 
git push origin master

finished you have pushed your code to your github

Cough cough

>>> a,b,c = (1,2,3)
>>> a
1
>>> b
2
>>> c
3
>>> a,b,c = ({'test':'a'},{'test':'b'},{'test':'c'})
>>> a
{'test': 'a'}
>>> b
{'test': 'b'}
>>> c
{'test': 'c'}

I Kind of like to do it a bit different, i like to call "myself" if needed with an Action,

    private void AddRowToListView(ScannerRow row, bool suspend)
    {
        if (IsFormClosing)
            return;

        if (this.InvokeRequired)
        {
            var A = new Action(() => AddRowToListView(row, suspend));
            this.Invoke(A);
            return;
        }
         //as of here the Code is thread-safe

this is a handy pattern, the IsFormClosing is a field that i set to True when I am closing my form as there might be some background threads that are still running...

The universal tool for string formatting, sprintf:

$stamp = sprintf('%s%02s', $year, $month);

http://php.net/manual/en/function.sprintf.php

Here's the correct code for your service:

myApp.service('userService', [
  '$http', '$q', '$rootScope', '$location', function($http, $q, $rootScope, $location) {

    var user = {
      access: false
    };

    var me = this;

    this.initialized = false;
    this.isAuthenticated = function() {

      var deferred = $q.defer();
      user = {
        first_name: 'First',
        last_name: 'Last',
        email: '[email protected]',
        access: 'institution'
      };
      deferred.resolve(user);
      me.initialized = true;

      return deferred.promise;
    };
  }
]);

Then you controller should align accordingly:

myApp.run([
  '$rootScope', 'userService', function($rootScope, userService) {
    return userService.isAuthenticated().then(function(user) {
      if (user) {
        // You have access to the object you passed in the service, not to the response.
        // You should either put response.data on the user or use a different property.
        return $rootScope.$broadcast('login', user.email);  
      } else {
        return userService.logout();
      }
    });
  }
]);

Few points to note about the service:

• Expose in a service only what needs to be exposed. User should be kept internally and be accessed by getters only.

• When in functions, use 'me' which is the service to avoid edge cases of this with javascript.

• I guessed what initialized was meant to do, feel free to correct me if I guessed wrong.

@media all and (orientation:portrait) {
/* Style adjustments for portrait mode goes here */
}

@media all and (orientation:landscape) {
  /* Style adjustments for landscape mode goes here */
}

but it still looks like you have to experiment

This was answered ages ago and probably not relevant, but just in case. When I was confronted with this issue, I simply used an if statement instead of switch, it solved the error. It is of course a workaround and probably not the "right" solution, but in my case it was just enough.

Edit: 2021.01.21

This Answer is a bit misleading, And I would like to clarify it.

1. Replacing a switch statement with an if should not be considered as a goto solution, there are very good reasons why both concepts of switch and if exist in software development, as well as performance matters to consider when choosing between the two.
2. Although I provide a solution to the presented error, My answer sheds no light on "why" the problem occurs but instead offers a way around the problem.

In my specific case, using an if statement instead was just enough to solve the problem. Developers should take the time and decide if this is the right solution for the current problem you have at hand.

Thus this answer should be considered solely as a workaround in specific cases as stated in my first response, and by no means as the correct answer to this question

The browser only allows numerical inputs when the type is set to "number". Details here.

You can use the type="text" and filter out any other than numerical input using JavaScript like descripted here

Below is my script for converting all files recursively. You can specify folders or files to exclude.

$excludeFolders = "node_modules|dist|.vs";
$excludeFiles = ".*\.map.*|.*\.zip|.*\.png|.*\.ps1"

Function Dos2Unix {
    [CmdletBinding()]
    Param([Parameter(ValueFromPipeline)] $fileName)

    Write-Host -Nonewline "."

    $fileContents = Get-Content -raw $fileName
    $containsCrLf = $fileContents | %{$_ -match "\r\n"}
    If($containsCrLf -contains $true)
    {
        Write-Host "`r`nCleaing file: $fileName"
        set-content -Nonewline -Encoding utf8 $fileName ($fileContents -replace "`r`n","`n")
    }
}

Get-Childitem -File "." -Recurse |
Where-Object {$_.PSParentPath -notmatch $excludeFolders} |
Where-Object {$_.PSPath -notmatch $excludeFiles} |
foreach { $_.PSPath | Dos2Unix }

In case of multiple type of select and/or if you want to remove already selected items one by one, directly within a dropdown list items, you can use something like:

jQuery("body").on("click", ".result-selected", function() {
    var locID = jQuery(this).attr('class').split('__').pop();
    // I have a class name: class="result-selected locvalue__209"
    var arrayCurrent = jQuery('#searchlocation').val();
    var index = arrayCurrent.indexOf(locID);
    if (index > -1) {
        arrayCurrent.splice(index, 1);
    }
    jQuery('#searchlocation').val(arrayCurrent).trigger('chosen:updated');
});

It depends on how your $('site-header') is constructed.

You can try to use $timeout with 0 delay. Something like:

return function(scope, element, attrs) {
    $timeout(function(){
        $('.main').height( $('.site-header').height() -  $('.site-footer').height() );
    });        
}

Explanations how it works: one, two.

Don't forget to inject $timeout in your directive:

.directive('sticky', function($timeout)

SELECT (column name) FROM (table name) WHERE (column name) < DATEADD(Day,-30,GETDATE());

Example.

SELECT `name`, `phone`, `product` FROM `tbmMember` WHERE `dateofServicw` < (Day,-30,GETDATE()); 

I tried the other solutions here, they work but I'm lazy so this is my solution

1. hover over the element to trigger expanded state
2. ctrl+shift+c
3. hover over element again
4. right click
5. navigate to the debugger

by right clicking it no longer registers mouse event since a context menu pops up, so you can move the mouse away safely

The Following:

.show-grid [class*="span"] {

means that all child elements of '.show-grid' with a class that CONTAINS the word 'span' in it will acquire those CSS properties.

<div class="show-grid">
  <div class="span">.span</div>
  <div class="span6">span6</div>
  <div class="attention-span">attention</div>
  <div class="spanish">spanish</div>
  <div class="mariospan">mariospan</div>
  <div class="espanol">espanol</div>

  <div>
    <div class="span">.span</div>
  </div>

  <p class="span">span</p>
  <span class="span">I do GET HIT</span>

  <span>I DO NOT GET HIT since I need a class of 'span'</span>
</div>

<div class="span">I DO NOT GET HIT since I'm outside of .show-grid</span>

All of the elements get hit except for the <span> by itself.

In Regards to Bootstrap:

• span6 : this was Bootstrap 2's scaffolding technique which divided a section into a horizontal grid, based on parts of 12. Thus span6 would have a width of 50%.
• In the current day implementation of Bootstrap (v.3 and v.4), you now use the .col-* classes (e.g. col-sm-6), which also specifies a media breakpoint to handle responsiveness when the window shrinks below a certain size. Check Bootstrap 4.1 and Bootstrap 3.3.7 for more documentation. I would recommend going with a later Bootstrap nowadays

you might use default parameters in your function and then just pass the entire dataset itself, since the dataset is already a DOMStringMap Object

<div data-uid="aaa" data-name="bbb" data-value="ccc"
onclick="fun(this.dataset)">

<script>
const fun = ({uid:'ddd', name:'eee', value:'fff', other:'default'} = {}) { 
    // 
}
</script>

that way, you can deal with any data-values that got set in the html tag, or use defaults if they weren't set - that kind of thing

maybe not in this situation, but in others, it might be advantageous to put all your preferences in a single data-attribute

<div data-all='{"uid":"aaa","name":"bbb","value":"ccc"}'
onclick="fun(JSON.parse(this.dataset.all))">

there are probably more terse ways of doing that, if you already know certain things about the order of the data

<div data-all="aaa,bbb,ccc" onclick="fun(this.dataset.all.split(','))">

Following is the method in C# to get the enum value by string

///
/// Method to get enumeration value from string value.
///
///
///

public T GetEnumValue<T>(string str) where T : struct, IConvertible
{
    if (!typeof(T).IsEnum)
    {
        throw new Exception("T must be an Enumeration type.");
    }
    T val = ((T[])Enum.GetValues(typeof(T)))[0];
    if (!string.IsNullOrEmpty(str))
    {
        foreach (T enumValue in (T[])Enum.GetValues(typeof(T)))
        {
            if (enumValue.ToString().ToUpper().Equals(str.ToUpper()))
            {
                val = enumValue;
                break;
            }
        }
    }

    return val;
}

Following is the method in C# to get the enum value by int.

///
/// Method to get enumeration value from int value.
///
///
///

public T GetEnumValue<T>(int intValue) where T : struct, IConvertible
{
    if (!typeof(T).IsEnum)
    {
        throw new Exception("T must be an Enumeration type.");
    }
    T val = ((T[])Enum.GetValues(typeof(T)))[0];

    foreach (T enumValue in (T[])Enum.GetValues(typeof(T)))
    {
        if (Convert.ToInt32(enumValue).Equals(intValue))
        {
            val = enumValue;
            break;
        }             
    }
    return val;
}

If I have an enum as follows:

public enum TestEnum
{
    Value1 = 1,
    Value2 = 2,
    Value3 = 3
}

then I can make use of above methods as

TestEnum reqValue = GetEnumValue<TestEnum>("Value1");  // Output: Value1
TestEnum reqValue2 = GetEnumValue<TestEnum>(2);        // OutPut: Value2

Hope this will help.

I know this is too late

There are many other solutions already but still...

def power_set(lst):
    pw_set = [[]]

    for i in range(0,len(lst)):
        for j in range(0,len(pw_set)):
            ele = pw_set[j].copy()
            ele = ele + [lst[i]]
            pw_set = pw_set + [ele]

    return pw_set

int is the C# language's shortcut for System.Int32

Whilst this does mean that Microsoft could change this mapping, a post on FogCreek's discussions stated [source]

"On the 64 bit issue -- Microsoft is indeed working on a 64-bit version of the .NET Framework but I'm pretty sure int will NOT map to 64 bit on that system.

Reasons:

1. The C# ECMA standard specifically says that int is 32 bit and long is 64 bit.

2. Microsoft introduced additional properties & methods in Framework version 1.1 that return long values instead of int values, such as Array.GetLongLength in addition to Array.GetLength.

So I think it's safe to say that all built-in C# types will keep their current mapping."

just posting in case anyone else has the same error...

I was using 'await' outside of an 'async' function and for whatever reason that results in a 'missing ) after argument list' error.

The solution was to make the function asynchronous

function functionName(args) {}

becomes

async function functionName(args) {}

I can show you how I used it

  function GetDenierValue() {
        var denierid = $("#productDenierid").val() == '' ? 0 : $("#productDenierid").val();
        var param = { 'productDenierid': denierid };
        $.ajax({
            url: "/Admin/ProductComposition/GetDenierValue",
            dataType: "json",
            contentType: "application/json;charset=utf-8",
            type: "POST",
            data: JSON.stringify(param),
            success: function (msg) {
                if (msg != null) {
                    return msg.URL;
                }
            }
        });
    }

Also on OS X (El Capitan), been having this same issue all morning.

I was running the command "npm install -g grunt-cli" command from within a directory where my project was.

I tried again from my home directory (i.e. 'cd ~') and it installed as before, except now I can run the grunt command and it is recognised.

In my case the missing type was referencing an import for java class in a dependent jar. For some reason my project file was missing the javabuilder and therefore couldnt resolve the path to the import.

Why it was missing in the first place I don't know, but adding these lines in fixed the error.

<buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
</buildCommand>

The main difference between the two is where it is stored and how it is accessed.

$.fn.attr stores the information directly on the element in attributes which are publicly visible upon inspection, and also which are available from the element's native API.

$.fn.data stores the information in a ridiculously obscure place. It is located in a closed over local variable called data_user which is an instance of a locally defined function Data. This variable is not accessible from outside of jQuery directly.

Data set with attr()

• accessible from $(element).attr('data-name')
• accessible from element.getAttribute('data-name'),
• if the value was in the form of data-name also accessible from $(element).data(name) and element.dataset['name'] and element.dataset.name
• visible on the element upon inspection
• cannot be objects

Data set with .data()

• accessible only from .data(name)
• not accessible from .attr() or anywhere else
• not publicly visible on the element upon inspection
• can be objects

Android Studio 3.0 below working method:
Find your old zipped project.
If you have built the apk, you'll find the password in file:

Project\.gradle\2.14.1\taskArtifacts\taskArtifacts.bin

Pandroid.injected.signing.store.password=password

If you don't have zipped project, search your git repositories if you have .gradle folder pushed or not.
Otherwise you'll have to recover files and search files by content "Pandroid.injected.signing.store.password".

I believe you just need to put the list 'bullet' outside of the padding.

li {
    list-style-position: outside;
    padding-left: 1em;
}

There are multiple function to printing array content that each has features.

print_r()

Prints human-readable information about a variable.

$arr = ["a", "b", "c"];

echo "<pre>";
print_r($arr);
echo "</pre>";

Array
(
    [0] => a
    [1] => b
    [2] => c
)

var_dump()

Displays structured information about expressions that includes its type and value.

echo "<pre>";
var_dump($arr);
echo "</pre>";

array(3) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
}

var_export()

Displays structured information about the given variable that returned representation is valid PHP code.

echo "<pre>";
var_export($arr);
echo "</pre>";

array (
  0 => 'a',
  1 => 'b',
  2 => 'c',
)

Note that because browser condense multiple whitespace characters (including newlines) to a single space (answer) you need to wrap above functions in <pre></pre> to display result in correct format.

Also there is another way to printing array content with certain conditions.

echo

Output one or more strings. So if you want to print array content using echo, you need to loop through array and in loop use echo to printing array items.

foreach ($arr as $key=>$item){
    echo "$key => $item <br>";
}

0 => a 
1 => b 
2 => c 

Thread.sleep can throw an InterruptedException which is a checked exception. All checked exceptions must either be caught and handled or else you must declare that your method can throw it. You need to do this whether or not the exception actually will be thrown. Not declaring a checked exception that your method can throw is a compile error.

You either need to catch it:

try {
    Thread.sleep(1000);
} catch (InterruptedException e) {
    e.printStackTrace();
    // handle the exception...        
    // For example consider calling Thread.currentThread().interrupt(); here.
}

Or declare that your method can throw an InterruptedException:

public static void main(String[]args) throws InterruptedException

I wrote my self a helper method to get patterns for this.

public static String getPattern(int month) {
    String first = "MMMM dd";
    String last = ", yyyy";
    String pos = (month == 1 || month == 21 || month == 31) ? "'st'" : (month == 2 || month == 22) ? "'nd'" : (month == 3 || month == 23) ? "'rd'" : "'th'";
    return first + pos + last;
}

and then we can call it as

LocalDate localDate = LocalDate.now();//For reference
int month = localDate.getDayOfMonth();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern(getPattern(month));
String date = localDate.format(formatter);
System.out.println(date);

the output is

December 12th, 2018

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

import os

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

Short And working Solution :

Follow Simple Steps

Steps

Step 1 : Override onSaveInstanceState state in respective fragment. And remove super method from it.

 @Override
public void onSaveInstanceState( Bundle outState ) {

}  

Step 2 : Use fragmentTransaction.commitAllowingStateLoss( );

instead of fragmentTransaction.commit( ); while fragment operations.

Not sure what the problem is, this seems to work just fine?

marksyzm's answer works well, but it does not return false for Infinity as Infinity is techinicly not a number.

i came up with a isNumber function that will check if it is a number.

function isNumber(i) {_x000D_
    return !isNaN(i && i !== true ? Number(i) : parseFloat(i)) && [Number.POSITIVE_INFINITY, Number.NEGATIVE_INFINITY].indexOf(i) === -1;_x000D_
}_x000D_
_x000D_
console.log(isNumber(Infinity));_x000D_
console.log(isNumber("asdf"));_x000D_
console.log(isNumber(1.4));_x000D_
console.log(isNumber(NaN));_x000D_
console.log(isNumber(Number.MAX_VALUE));_x000D_
console.log(isNumber("1.68"));

UPDATE: i noticed that this code fails for some parameters, so i made it better.

function isNumber(i) {//function for checking if parameter is number_x000D_
if(!arguments.length) {_x000D_
throw new SyntaxError("not enough arguments.");_x000D_
 } else if(arguments.length > 1) {_x000D_
throw new SyntaxError("too many arguments.");_x000D_
 } else if([Number.NEGATIVE_INFINITY, Number.POSITIVE_INFINITY].indexOf(i) !== -1) {_x000D_
throw new RangeError("number cannot be \xB1infinity.");_x000D_
 } else if(typeof i === "object" && !(i instanceof RegExp) && !(i instanceof Number) && !(i === null)) {_x000D_
throw new TypeError("parameter cannot be object/array.");_x000D_
 } else if(i instanceof RegExp) {_x000D_
throw new TypeError("parameter cannot be RegExp.");_x000D_
 } else if(i == null || i === undefined) {_x000D_
throw new ReferenceError("parameter is null or undefined.");_x000D_
 } else {_x000D_
return !isNaN(i && i !== true ? Number(i) : parseFloat(i)) && (i === i);_x000D_
 }_x000D_
}_x000D_
console.log(isNumber(Infinity));_x000D_
console.log(isNumber(this));_x000D_
console.log(isNumber(/./ig));_x000D_
console.log(isNumber(null));

For those who use JSF2.2+ and cannot pass autofocus as an attribute without value to it, use this:

 p:autofocus="true"

And add it to the namespace p (Also often used pt. Whatever you like).

<html ... xmlns:p="http://java.sun.com/jsf/passthrough">

In C, \0 denotes a character with value zero. The following are identical:

char a = 0;
char b = '\0';

The utility of this escape sequence is greater inside string literals, which are arrays of characters:

char arr[] = "abc\0def\0ghi\0";

(Note that this array has two zero characters at the end, since string literals include a hidden, implicit terminal zero.)

If you're an Android developer you can use android.util.Base64 class for this purpose.

Is it possible to make a search by querySelectorAll using multiple unrelated conditions?

Yes, because querySelectorAll accepts full CSS selectors, and CSS has the concept of selector groups, which lets you specify more than one unrelated selector. For instance:

var list = document.querySelectorAll("form, p, legend");

...will return a list containing any element that is a form or p or legend.

CSS also has the other concept: Restricting based on more criteria. You just combine multiple aspects of a selector. For instance:

var list = document.querySelectorAll("div.foo");

...will return a list of all div elements that also (and) have the class foo, ignoring other div elements.

You can, of course, combine them:

var list = document.querySelectorAll("div.foo, p.bar, div legend");

...which means "Include any div element that also has the foo class, any p element that also has the bar class, and any legend element that's also inside a div."

In addition to Varun Achar's answer, this is the Java 8 variant I came up with, that uses java.time.LocalDate and ZonedDateTime instead of the old java.util.Date classes.

public class LocalDateDeserializer extends JsonDeserializer<LocalDate> {

    @Override
    public LocalDate deserialize(JsonParser jsonparser, DeserializationContext deserializationcontext) throws IOException {

        String string = jsonparser.getText();

        if(string.length() > 20) {
            ZonedDateTime zonedDateTime = ZonedDateTime.parse(string);
            return zonedDateTime.toLocalDate();
        }

        return LocalDate.parse(string);
    }
  }

clrscr is not standard C function. According to internet, it used to be a thing in old Borland C.
Is clrscr(); a function in C++?

I am using phpMyAdmin version 4.2.11. At the time of writing, my Status tab looks like this (a few options expanded; note "Current settings", bottom right):

Note, there are no directly visible "features" that allow for the enabling of things such as slow_query_log. So, I went digging on the internet because UI-oriented answers will only be relevant to a particular release and, therefore, will quickly become out of date. So, what do you do if you don't see a relevant answer, above?

As this article explains, you can run a global query to enable or disable the slow_query_log et al. The queries for enabling and disabling these logs are not difficult, so don't be afraid of them, e.g.

SET GLOBAL slow_query_log = 'ON';

From here, phpMyAdmin is pretty helpful and a bit of Googling will get you up to speed in no time. For instance, after I ran the above query, I can go back to the "Instructions/Setup" option under the Status tab's Monitor window and see this (note the further instructions):

Use absolute path:

extension_dir="C:\full\path\here"

First, you have to add a ListView, an EditText and a button into your activity_main.xml.

Now, in your ActivityMain:

private EditText editTxt;
private Button btn;
private ListView list;
private ArrayAdapter<String> adapter;
private ArrayList<String> arrayList;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    editTxt = (EditText) findViewById(R.id.editText);
    btn = (Button) findViewById(R.id.button);
    list = (ListView) findViewById(R.id.listView);
    arrayList = new ArrayList<String>();

    // Adapter: You need three parameters 'the context, id of the layout (it will be where the data is shown),
    // and the array that contains the data
    adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_item, arrayList);

    // Here, you set the data in your ListView
    list.setAdapter(adapter);

    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            // this line adds the data of your EditText and puts in your array
            arrayList.add(editTxt.getText().toString());
            // next thing you have to do is check if your adapter has changed
            adapter.notifyDataSetChanged();
        }
    });
}

This works for me, I hope I helped you

You can get this error if you use wrong mode when opening the file. For example:

    with open(output, 'wb') as output_file:
        print output_file.read()

In that code, I want to read the file, but I use mode wb instead of r or r+

I use text-align-center in a row like this

<div class="row tac">
    <h1>Centered content</h1>
</div>

<style>
 .tac { text-align: center}
</style>

If you are using version 1

Recaptcha.reload();

If you are using version 2

grecaptcha.reset();

window.history.back(); Sometimes it's an issue with javascript compatibility with ajax call or design-related challenges.

I would use this below function for go back with the refresh.

function GoBackWithRefresh(event) {
    if ('referrer' in document) {
        window.location = document.referrer;
        /* OR */
        //location.replace(document.referrer);
    } else {
        window.history.back();
    }
}

In your html, use:

<a href="#" onclick="GoBackWithRefresh();return false;">BACK</a>`

For more customization you can use history.js plugins.

What are -moz- and -webkit-?

CSS properties starting with -webkit-, -moz-, -ms- or -o- are called vendor prefixes.

Why do different browsers add different prefixes for the same effect?

A good explanation of vendor prefixes comes from Peter-Paul Koch of QuirksMode:

Originally, the point of vendor prefixes was to allow browser makers to start supporting experimental CSS declarations.

Let's say a W3C working group is discussing a grid declaration (which, incidentally, wouldn't be such a bad idea). Let's furthermore say that some people create a draft specification, but others disagree with some of the details. As we know, this process may take ages.

Let's furthermore say that Microsoft as an experiment decides to implement the proposed grid. At this point in time, Microsoft cannot be certain that the specification will not change. Therefore, instead of adding the grid to its CSS, it adds -ms-grid.

The vendor prefix kind of says "this is the Microsoft interpretation of an ongoing proposal." Thus, if the final definition of the grid is different, Microsoft can add a new CSS property grid without breaking pages that depend on -ms-grid.

UPDATE AS OF THE YEAR 2016

As this post 3 years old, it's important to mention that now most vendors do understand that these prefixes are just creating un-necessary duplicate code and that the situation where you need to specify 3 different CSS rules to get one effect working in all browser is an unwanted one.

As mentioned in this glossary about Mozilla's view on Vendor Prefix on May 3, 2016,

Browser vendors are now trying to get rid of vendor prefix for experimental features. They noticed that Web developers were using them on production Web sites, polluting the global space and making it more difficult for underdogs to perform well.

For example, just a few years ago, to set a rounded corner on a box you had to write:

-moz-border-radius: 10px 5px;
-webkit-border-top-left-radius: 10px;
-webkit-border-top-right-radius: 5px;
-webkit-border-bottom-right-radius: 10px;
-webkit-border-bottom-left-radius: 5px;
border-radius: 10px 5px;

But now that browsers have come to fully support this feature, you really only need the standardized version:

border-radius: 10px 5px;

Finding the right rules for all browsers

As still there's no standard for common CSS rules that work on all browsers, you can use tools like caniuse.com to check support of a rule across all major browsers.

You can also use pleeease.io/play. Pleeease is a Node.js application that easily processes your CSS. It simplifies the use of preprocessors and combines them with best postprocessors. It helps create clean stylesheets, support older browsers and offers better maintainability.

Input:

a {
  column-count: 3;
  column-gap: 10px;
  column-fill: auto;
}

Output:

a {
  -webkit-column-count: 3;
     -moz-column-count: 3;
          column-count: 3;
  -webkit-column-gap: 10px;
     -moz-column-gap: 10px;
          column-gap: 10px;
  -webkit-column-fill: auto;
     -moz-column-fill: auto;
          column-fill: auto;
}

An index is just a data structure that makes the searching faster for a specific column in a database. This structure is usually a b-tree or a hash table but it can be any other logic structure.

I have python 2.7.3 and this solved my problem:

pip install pysqlite

The first element of $myarray is the array of values you want. So, right now,

echo $myarray[0]['email']; // This outputs '[email protected]'

If you want that array to become $myarray, then you just have to do

$myarray = $myarray[0];

Now, $myarray['email'] etc. will output as expected.

I try with SUBSTRING_INDEX(string,delimiter,count)

mysql> SELECT SUBSTRING_INDEX('www.mysql.com', '.', 2);
-> 'www.mysql'

mysql> SELECT SUBSTRING_INDEX('www.mysql.com', '.', -2);
-> 'mysql.com'

see more on mysql.com http://dev.mysql.com/doc/refman/5.1/en/string-functions.html#function_substring-index

You can use the onclick attribute, just return false if you don't want continue;

<script type="text/javascript">
function confirm_alert(node) {
    return confirm("Please click on OK to continue.");
}
</script>
<a href="http://www.google.com" onclick="return confirm_alert(this);">Click Me</a>

$( "element" ).focusout(function() {
    //your code on element
})

The correct answer is

Options -Indexes

I'm using this easy solution. You can just add this library with gradle: https://github.com/fernandodev/easy-rating-dialog

compile 'com.github.fernandodev.easyratingdialog:easyratingdialog:+'

You need something like this, maybe it can be improved. This is a first attempt:

...
import org.springframework.core.env.PropertySource;
import org.springframework.core.env.AbstractEnvironment;
import org.springframework.core.env.Environment;
import org.springframework.core.env.MapPropertySource;
...

@Configuration
...
@org.springframework.context.annotation.PropertySource("classpath:/config/default.properties")
...
public class GeneralApplicationConfiguration implements WebApplicationInitializer 
{
    @Autowired
    Environment env;

    public void someMethod() {
        ...
        Map<String, Object> map = new HashMap();
        for(Iterator it = ((AbstractEnvironment) env).getPropertySources().iterator(); it.hasNext(); ) {
            PropertySource propertySource = (PropertySource) it.next();
            if (propertySource instanceof MapPropertySource) {
                map.putAll(((MapPropertySource) propertySource).getSource());
            }
        }
        ...
    }
...

Basically, everything from the Environment that's a MapPropertySource (and there are quite a lot of implementations) can be accessed as a Map of properties.

scrollHeight is a regular javascript property so you don't need jQuery.

With Android API level (23), we are required to check for permissions. https://developer.android.com/training/permissions/requesting.html

I had your same problem, but the following worked for me and I am able to retrieve Location data successfully:

(1) Ensure you have your permissions listed in the Manifest:

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

(2) Ensure you request permissions from the user:

if ( ContextCompat.checkSelfPermission( this, android.Manifest.permission.ACCESS_COARSE_LOCATION ) != PackageManager.PERMISSION_GRANTED ) {

            ActivityCompat.requestPermissions( this, new String[] {  android.Manifest.permission.ACCESS_COARSE_LOCATION  },
                                                LocationService.MY_PERMISSION_ACCESS_COURSE_LOCATION );
        }

(3) Ensure you use ContextCompat as this has compatibility with older API levels.

(4) In your location service, or class that initializes your LocationManager and gets the last known location, we need to check the permissions:

if ( Build.VERSION.SDK_INT >= 23 &&
             ContextCompat.checkSelfPermission( context, android.Manifest.permission.ACCESS_FINE_LOCATION ) != PackageManager.PERMISSION_GRANTED &&
             ContextCompat.checkSelfPermission( context, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            return  ;
        }

(5) This approach only worked for me after I included @TargetApi(23) at the top of my initLocationService method.

(6) I also added this to my gradle build:

compile 'com.android.support:support-v4:23.0.1'

Here is my LocationService for reference:

public class LocationService implements LocationListener  {

    //The minimum distance to change updates in meters
    private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 0; // 10 meters

    //The minimum time between updates in milliseconds
    private static final long MIN_TIME_BW_UPDATES = 0;//1000 * 60 * 1; // 1 minute

    private final static boolean forceNetwork = false;

    private static LocationService instance = null;

    private LocationManager locationManager;
    public Location location;
    public double longitude;
    public double latitude; 


    /**
     * Singleton implementation
     * @return
     */
    public static LocationService getLocationManager(Context context)     {
        if (instance == null) {
            instance = new LocationService(context);
        }
        return instance;
    }

    /**
     * Local constructor
     */
    private LocationService( Context context )     {

        initLocationService(context); 
        LogService.log("LocationService created");
    }



    /**
     * Sets up location service after permissions is granted
     */
    @TargetApi(23)
    private void initLocationService(Context context) {


        if ( Build.VERSION.SDK_INT >= 23 &&
             ContextCompat.checkSelfPermission( context, android.Manifest.permission.ACCESS_FINE_LOCATION ) != PackageManager.PERMISSION_GRANTED &&
             ContextCompat.checkSelfPermission( context, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            return  ;
        }

        try   {
            this.longitude = 0.0;
            this.latitude = 0.0;
            this.locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);

            // Get GPS and network status
            this.isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
            this.isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

            if (forceNetwork) isGPSEnabled = false;

            if (!isNetworkEnabled && !isGPSEnabled)    {
                // cannot get location
                this.locationServiceAvailable = false;
            }
            //else
            {
                this.locationServiceAvailable = true;

                if (isNetworkEnabled) {
                    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
                            MIN_TIME_BW_UPDATES,
                            MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                    if (locationManager != null)   {
                        location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                        updateCoordinates();
                    }
                }//end if

                if (isGPSEnabled)  {
                    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
                            MIN_TIME_BW_UPDATES,
                            MIN_DISTANCE_CHANGE_FOR_UPDATES, this);

                    if (locationManager != null)  {
                        location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
                        updateCoordinates();
                    }
                }
            }
        } catch (Exception ex)  {
            LogService.log( "Error creating location service: " + ex.getMessage() );

        }
    }       


    @Override
    public void onLocationChanged(Location location)     {
        // do stuff here with location object 
    }
}

I tested with an Android Lollipop device so far only. Hope this works for you.

The macro ARRAYELEMENTCOUNT(x) that everyone is making use of evaluates incorrectly. This, realistically, is just a sensitive matter, because you can't have expressions that result in an 'array' type.

/* Compile as: CL /P "macro.c" */
# define ARRAYELEMENTCOUNT(x) (sizeof (x) / sizeof (x[0]))

ARRAYELEMENTCOUNT(p + 1);

Actually evaluates as:

(sizeof (p + 1) / sizeof (p + 1[0]));

Whereas

/* Compile as: CL /P "macro.c" */
# define ARRAYELEMENTCOUNT(x) (sizeof (x) / sizeof (x)[0])

ARRAYELEMENTCOUNT(p + 1);

It correctly evaluates to:

(sizeof (p + 1) / sizeof (p + 1)[0]);

This really doesn't have a lot to do with the size of arrays explicitly. I've just noticed a lot of errors from not truly observing how the C preprocessor works. You always wrap the macro parameter, not an expression in might be involved in.

This is correct; my example was a bad one. But that's actually exactly what should happen. As I previously mentioned p + 1 will end up as a pointer type and invalidate the entire macro (just like if you attempted to use the macro in a function with a pointer parameter).

At the end of the day, in this particular instance, the fault doesn't really matter (so I'm just wasting everyone's time; huzzah!), because you don't have expressions with a type of 'array'. But really the point about preprocessor evaluation subtles I think is an important one.

Like the other answers say, you can't remove an item from a collection you're iterating over. You can get around this by explicitly using an Iterator and removing the item there.

Iterator<Item> iter = list.iterator();
while(iter.hasNext()) {
  Item blah = iter.next();
  if(...) {
    iter.remove(); // Removes the 'current' item
  }
}

use Below command in terminal

php artisan cache:clear
php artisan route:cache 
php artisan config:cache 
php artisan view:clear

Here's my 2 cents:

  IEnumerable<string> Split(string str, int chunkSize)
  {
     while (!string.IsNullOrWhiteSpace(str))
     {
        var chunk = str.Take(chunkSize).ToArray();
        str = str.Substring(chunk.Length);
        yield return new string(chunk);

     }

  }//Split

I know this is an old question but I came across it while trying to solve this same issue. I thought it'd be worth sharing this solution I hadn't found anywhere else.

Basically the solution is to use CSS to hide the <input> element and style a <label> around it to look like a button. Click the 'Run code snippet' button to see the results.

I had used a JavaScript solution before that worked fine too but it is nice to solve a 'presentation' issue with just CSS.

Use textView.setTypeface(Typeface tf, int style); to set style property of the TextView. See the developer documentation for more info.

If you want to just shift everything down you can use:

Rows(1).Insert shift:=xlShiftDown

Similarly to shift everything over:

Columns(1).Insert shift:=xlShiftRight

The most simple and the correct way is to use Record type Record<string, string>

const myVar : Record<string, string> = {
   key1: 'val1',
   key2: 'val2',
}

ESLint defaults to ES5 syntax-checking. You'll want to override to the latest well-supported version of JavaScript.

Try adding a .eslintrc file to your project. Inside it:

{
    "parserOptions": {
        "ecmaVersion": 2017
    },

    "env": {
        "es6": true
    }
}

Hopefully this helps.

EDIT: I also found this example .eslintrc which might help.

You should install IIS sub components from

Control Panel -> Programs and Features -> Turn Windows features on or off

Internet Information Services has subsection World Wide Web Services / Application Development Features

There you must check ASP.NET (.NET Extensibility, ISAPI Extensions, ISAPI Filters will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.

Run from cmd:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir

Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.

Also, look at this answer.

Put this in your .vimrc configuration file.

I started creating a Node.js/browserify application following the Cross Platform JavaScript blog post. And I ran into this issue, because my brand new Gruntfile didn't pass jshint.

Luckily I found an answer in the Leanpub book on Grunt:

If we try it now, we will scan our Gruntfile… and get some errors:

$ grunt jshint

Running "jshint:all" (jshint) task
Linting Gruntfile.js...ERROR
[L1:C1] W097: Use the function form of "use strict".
'use strict';
Linting Gruntfile.js...ERROR
[L3:C1] W117: 'module' is not defined.
module.exports = function (grunt) {

Warning: Task "jshint:all" failed. Use --force to continue.

Both errors are because the Gruntfile is a Node program, and by default JSHint does not recognise or allow the use of module and the string version of use strict. We can set a JSHint rule that will accept our Node programs. Let’s edit our jshint task configuration and add an options key:

jshint: {
  options: {
    node: true
  },
}

Adding node: true to the jshint options, to put jshint into "Node mode", removed both errors for me.

NSLocationWhenInUseUsageDescription = Request permission to use location service when the apps is in background. in your plist file.

If this works then please vote the answer.

Step 1. Figure out which errors you want to trap:

If the table does not exist:

SQL> drop table x;
drop table x
           *
ERROR at line 1:
ORA-00942: table or view does not exist

If the table is in use:

SQL> create global temporary table t (data varchar2(4000));

Table created.

Use the table in another session. (Notice no commit or anything after the insert.)

SQL> insert into t values ('whatever');

1 row created.

Back in the first session, attempt to drop:

SQL> drop table t;
drop table t
           *
ERROR at line 1:
ORA-14452: attempt to create, alter or drop an index on temporary table already in use

So the two errors to trap:

1. ORA-00942: table or view does not exist
2. ORA-14452: attempt to create, alter or drop an index on temporary table already in use

See if the errors are predefined. They aren't. So they need to be defined like so:

create or replace procedure p as
    table_or_view_not_exist exception;
    pragma exception_init(table_or_view_not_exist, -942);
    attempted_ddl_on_in_use_GTT exception;
    pragma exception_init(attempted_ddl_on_in_use_GTT, -14452);
begin
    execute immediate 'drop table t';

    exception 
        when table_or_view_not_exist then
            dbms_output.put_line('Table t did not exist at time of drop. Continuing....');

        when attempted_ddl_on_in_use_GTT then
            dbms_output.put_line('Help!!!! Someone is keeping from doing my job!');
            dbms_output.put_line('Please rescue me');
            raise;
end p;

And results, first without t:

SQL> drop table t;

Table dropped.

SQL> exec p;
Table t did not exist at time of drop. Continuing....

PL/SQL procedure successfully completed.

And now, with t in use:

SQL> create global temporary table t (data varchar2(4000));

Table created.

In another session:

SQL> insert into t values (null);

1 row created.

And then in the first session:

SQL> exec p;
Help!!!! Someone is keeping from doing my job!
Please rescue me
BEGIN p; END;

*
ERROR at line 1:
ORA-14452: attempt to create, alter or drop an index on temporary table already in use

Pay attention, if you use cv.CV_THRESH_BINARY means every pixel greater than threshold becomes the maxValue (in your case 255), otherwise the value is 0. Obviously if your threshold is 0 everything becomes white (maxValue = 255) and if the value is 255 everything becomes black (i.e. 0).

If you don't want to work out a threshold, you can use the Otsu's method. But this algorithm only works with 8bit images in the implementation of OpenCV. If your image is 8bit use the algorithm like this:

cv.Threshold(im_gray_mat, im_bw_mat, threshold, 255, cv.CV_THRESH_BINARY | cv.CV_THRESH_OTSU);

No matter the value of threshold if you have a 8bit image.

The problem exists in old versions on the iOS. in the latest, the right-to-left works well. What I did, is as follows:

first I check the iOS version:

if (![self compareCurVersionTo:4 minor:3 point:0])

Than:

// set RTL on the start on each line (except the first)  
myUITextView.text = [myUITextView.text stringByReplacingOccurrencesOfString:@"\n"
                                                           withString:@"\u202B\n"];

You can create an iterator in Python 3.x or a list in Python 2.x by using:

filter(r.match, list)

To convert the Python 3.x iterator to a list, simply cast it; list(filter(..)).

You can groupby on cols 'A' and 'B' and call size and then reset_index and rename the generated column:

In [26]:

df1.groupby(['A','B']).size().reset_index().rename(columns={0:'count'})
Out[26]:
     A    B  count
0   no   no      1
1   no  yes      2
2  yes   no      4
3  yes  yes      3

update

A little explanation, by grouping on the 2 columns, this groups rows where A and B values are the same, we call size which returns the number of unique groups:

In[202]:
df1.groupby(['A','B']).size()

Out[202]: 
A    B  
no   no     1
     yes    2
yes  no     4
     yes    3
dtype: int64

So now to restore the grouped columns, we call reset_index:

In[203]:
df1.groupby(['A','B']).size().reset_index()

Out[203]: 
     A    B  0
0   no   no  1
1   no  yes  2
2  yes   no  4
3  yes  yes  3

This restores the indices but the size aggregation is turned into a generated column 0, so we have to rename this:

In[204]:
df1.groupby(['A','B']).size().reset_index().rename(columns={0:'count'})

Out[204]: 
     A    B  count
0   no   no      1
1   no  yes      2
2  yes   no      4
3  yes  yes      3

groupby does accept the arg as_index which we could have set to False so it doesn't make the grouped columns the index, but this generates a series and you'd still have to restore the indices and so on....:

In[205]:
df1.groupby(['A','B'], as_index=False).size()

Out[205]: 
A    B  
no   no     1
     yes    2
yes  no     4
     yes    3
dtype: int64

Even simpler, use path/filepath:

package main    

import (
    "fmt"
    "log"
    "path/filepath"
)

func main() {
    files, err := filepath.Glob("*")
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(files) // contains a list of all files in the current directory
}

In SpringBoot 2.1, I found another solution. Extend standard factory class method getTomcatWebServer. And then return it as a bean from anywhere.

public class CustomTomcatServletWebServerFactory extends TomcatServletWebServerFactory {

    @Override
    protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
        System.setProperty("catalina.useNaming", "true");
        tomcat.enableNaming();
        return new TomcatWebServer(tomcat, getPort() >= 0);
    }
}

@Component
public class TomcatConfiguration {
    @Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new CustomTomcatServletWebServerFactory();

        return factory;
    }

Loading resources from context.xml doesn't work though. Will try to find out.

You can use this method:

For the links if you use linkText(); it is more effective than the any other locator.

driver.findElement(By.linkText("App Configuration")).click();

If you want to set the Cache-Control header, there's nothing in the IIS7 UI to do this, sadly.

You can however drop this web.config in the root of the folder or site where you want to set it:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <staticContent>
      <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="7.00:00:00" />
    </staticContent>
  </system.webServer>
</configuration>

That will inform the client to cache content for 7 days in that folder and all subfolders.

You can also do this by editing the IIS7 metabase via appcmd.exe, like so:

\Windows\system32\inetsrv\appcmd.exe 
  set config "Default Web Site/folder" 
  -section:system.webServer/staticContent 
  -clientCache.cacheControlMode:UseMaxAge

\Windows\system32\inetsrv\appcmd.exe 
  set config "Default Web Site/folder" 
  -section:system.webServer/staticContent 
  -clientCache.cacheControlMaxAge:"7.00:00:00"

On a Mac, I found the output contained the information I was looking for:

$> npm install -g karma
...
...
> [email protected] install /usr/local/share/npm/lib/node_modules/karma/node_modules/socket.io/node_modules/socket.io-client/node_modules/ws
> (node-gyp rebuild 2> builderror.log) || (exit 0)
...
$> ls /usr/local/share/npm/bin
karma nf

After adding /usr/local/share/npm/bin to the export PATH line in my .bash_profile, saving it, and sourceing it, I was able to run

$> karma --help

normally.

Just create this class and add it to your element to be centered.

.navbar-center {
  margin-left: auto;
  margin-right: auto;
}

You should really use the following instead (works in all newer browsers):

window.addEventListener('DOMContentLoaded', init, false);

I'm using Jquery Load to handels this, works great for me. check out my code from my project. I need to refresh with arguments to put Javascript variable into php

if (isset($_GET['language'])){
    $language = $_GET['language'];
}else{
    echo '<script>';    
    echo '  var userLang = navigator.language || navigator.userLanguage;';
    echo '  if(userLang.search("zh") != -1) {';
    echo '      var language = "chn";';
    echo '  }else{';
    echo '      var language = "eng";';
    echo '  }';
    echo '$("html").load("index.php","language=" + language);';
    echo '</script>';
    die;
}

By Default angular return responseType as Json, but we can configure below types according to your requirement.

responseType: 'arraybuffer'|'blob'|'json'|'text'

Ex:

this.http.post(
    'http://localhost:8080/order/addtocart', 
    { dealerId: 13, createdBy: "-1", productId, quantity }, 
    { headers, responseType: 'text'});

Run from your project folder:

$ ionic info

Cordova CLI: 5.0.0
Ionic Version: 1.0.1
Ionic CLI Version: 1.6.1
Ionic App Lib Version: 0.3.3
OS: Windows 7 SP1
Node Version: v0.12.2

If your CLI is old enough, it will say "info is not a valid task" and you can use this:

$ ionic lib

Local Ionic version: 1.0.1  (C:\stuff\july21app\www\lib\ionic\version.json)
Latest Ionic version: 1.0.1  (released 2015-06-30)
* Local version up to date

In my case problem was at context.xml file of my project.

The following from context.xml causes the java.lang.AbstractMethodError, since we didn't show the datasource factory.

<Resource name="jdbc/myoracle"
              auth="Container"
              type="javax.sql.DataSource"
              driverClassName="oracle.jdbc.OracleDriver"
              url="jdbc:oracle:thin:@(DESCRIPTION = ... "
              username="****" password="****" maxActive="10" maxIdle="1"
              maxWait="-1" removeAbandoned="true"/> 

Simpy adding factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" solved the issue:

<Resource name="jdbc/myoracle"
              auth="Container"
              factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"  type="javax.sql.DataSource"
              driverClassName="oracle.jdbc.OracleDriver"
              url="jdbc:oracle:thin:@(DESCRIPTION = ... "
              username="****" password="****" maxActive="10" maxIdle="1"
              maxWait="-1" removeAbandoned="true"/>

To make sure I reproduced the issue several times by removing factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" from Resource

According to the docs, you can just do:

select INDEX_NAME, TABLE_OWNER, TABLE_NAME, UNIQUENESS from USER_INDEXES

or

select INDEX_NAME, TABLE_OWNER, TABLE_NAME, UNIQUENESS from ALL_INDEXES

if you want all indexes...

Cleaning the Magento Logs using SSH :

login to shell(SSH) panel and go with root/shell folder.

execute the below command inside the shell folder

php -f log.php clean

enter this command to view the log data's size

php -f log.php status

This method will help you to clean the log data's very easy way.

Guess I'm too late...

Came across the same problem today; here is my solution using FileSystemObject:

Dim objFSO
Const ForReading = 1
Const ForWriting = 2
Dim objTS 'define a TextStream object
Dim strContents As String
Dim fileSpec As String

fileSpec = "C:\Temp\test.txt"
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTS = objFSO.OpenTextFile(fileSpec, ForReading)
strContents = objTS.ReadAll
strContents = Replace(strContents, "XXXXX", "YYYY")
objTS.Close

Set objTS = objFSO.OpenTextFile(fileSpec, ForWriting)
objTS.Write strContents
objTS.Close

You can only add folders or jar files to a class loader. So if you have a single class file, you need to put it into the appropriate folder structure first.

Here is a rather ugly hack that adds to the SystemClassLoader at runtime:

import java.io.IOException;
import java.io.File;
import java.net.URLClassLoader;
import java.net.URL;
import java.lang.reflect.Method;

public class ClassPathHacker {

  private static final Class[] parameters = new Class[]{URL.class};

  public static void addFile(String s) throws IOException {
    File f = new File(s);
    addFile(f);
  }//end method

  public static void addFile(File f) throws IOException {
    addURL(f.toURL());
  }//end method


  public static void addURL(URL u) throws IOException {

    URLClassLoader sysloader = (URLClassLoader) ClassLoader.getSystemClassLoader();
    Class sysclass = URLClassLoader.class;

    try {
      Method method = sysclass.getDeclaredMethod("addURL", parameters);
      method.setAccessible(true);
      method.invoke(sysloader, new Object[]{u});
    } catch (Throwable t) {
      t.printStackTrace();
      throw new IOException("Error, could not add URL to system classloader");
    }//end try catch

   }//end method

}//end class

The reflection is necessary to access the protected method addURL. This could fail if there is a SecurityManager.

May be your JUnit launch configuration was for a individual test class, and you somehow changed that config to "run all tests in a source folder, package or project"

But that could trigger the "No tests found with test runner 'JUnit 4'" error message.

Or you did a modification in your test class, removing the @Test annotation.
See this wiki page.

I had this issue on the server I was deploying to, and determined that I did not need

Microsoft.CodeDom.Providers.DotNetCompilerPlatform

So, I uninstalled it via nuget, and removed the reference in the web config. No more issues.

I originally tried to added target node to the .proj file as mentioned in some of the other answers, but that just lead to another error where the msbuild could not copy the pagefile.sys which seemed from what I read to be a bug in the nuget package.

You can use map function and pythons inbuilt sum() function. It simplifies the solution. And reduces the complexity.
a=map(int,raw_input().split())
sum(a)
Done!

If you are using the Poco library, here is a portable way to delete a directory.

#include "Poco/File.h"
...
...
Poco::File fooDir("/path/to/your/dir");
fooDir.remove(true);

The remove function when called with "true" means recursively delete all files and sub directories in a directory.

.NET Framework provides many collection classes too. You can use Dictionary in C#. Please find the below msdn link for details and samples http://msdn.microsoft.com/en-us/library/xfhwa508.aspx

From the definition of height:

Applies to: all elements but non-replaced inline elements, table columns, and column groups

An a element is, by default an inline element (and it is non-replaced).

You need to change the display (directly with the display property or indirectly, e.g. with float).
