The selected answer would work for as long as you know the key itself that you want to delete but if it should be truly dynamic you would need to use the [] notation instead of the dot notation.

For example:

var keyToDelete = "key1";
var myObj = {"test": {"key1": "value", "key2": "value"}}

//that will not work.
delete myObj.test.keyToDelete 

instead you would need to use:

delete myObj.test[keyToDelete];

Substitute the dot notation with [] notation for those values that you want evaluated before being deleted.

Gmail requires you to use a secure connection. This can be set in your web.config like this:

<network host="smtp.gmail.com" enableSsl="true" ... />

OR

The SSL should be enable on the webserver as well. Refer following link

I found the below command much more convenient. If you want to copy lines from 6 to 12 and paste from the current cursor position.

:6,12 co .

If you want to copy lines from 6 to 12 and paste from 100th line.

:6,12t100

We had this discussion among the development team at work a week or so ago, and we almost unanimously went for empty collection. One person wanted to return null for the same reason Mike specified above.

Note that 1>&2 cannot be used interchangeably with 2>&1.

Imagine your command depends on piping, for example:
docker logs 1b3e97c49e39 2>&1 | grep "some log"
grepping will happen across both stderr and stdout since stderr is basically merged into stdout.

However, if you try:
docker logs 1b3e97c49e39 1>&2 | grep "some log",
grepping will not really search anywhere at all because Unix pipe is connecting processes via connecting stdout | stdin, and stdout in the second case was redirected to stderr in which Unix pipe has no interest.

If you are working on spring/mvn project you can use this command:

mvn package -DskipTests

The jar file will be saved on target directoy.

i think you can download the latest android SDK and use it.i do this and fixed the problem and work well. here is the link: http://developer.android.com/sdk/index.html#download

Well, I faced a similar problem but on unit tests.

Using SharpTestsEx you can check if a property existis. I use this testing my controllers, because since the JSON object is dynamic, someone can change the name and forget to change it in the javascript or something, so testing for all properties when writing the controller should increase my safety.

Example:

dynamic testedObject = new ExpandoObject();
testedObject.MyName = "I am a testing object";

Now, using SharTestsEx:

Executing.This(delegate {var unused = testedObject.MyName; }).Should().NotThrow();
Executing.This(delegate {var unused = testedObject.NotExistingProperty; }).Should().Throw();

Using this, i test all existing properties using "Should().NotThrow()".

It's probably out of topic, but can be usefull for someone.

It's an old post but i'll leave here my javascript solution just in case someone need it.

1. I used transform: translateY(@px) because it should be lightweight to compute, high-performance-animations

2. I only tried this function with modern browsers, it won't work for old browsers where vendors are required (and IE of course)

There is a version for VS2005 as well, if you are not on 2008.

WARNING: Security researches have found several poisoned packages on PyPI, including a package named urllib, which will 'phone home' when installed. If you used pip install urllib some time after June 2017, remove that package as soon as possible.

You can't, and you don't need to.

urllib2 is the name of the library included in Python 2. You can use the urllib.request library included with Python 3, instead. The urllib.request library works the same way urllib2 works in Python 2. Because it is already included you don't need to install it.

If you are following a tutorial that tells you to use urllib2 then you'll find you'll run into more issues. Your tutorial was written for Python 2, not Python 3. Find a different tutorial, or install Python 2.7 and continue your tutorial on that version. You'll find urllib2 comes with that version.

Alternatively, install the requests library for a higher-level and easier to use API. It'll work on both Python 2 and 3.

I had this issue and the other fixes on this page didn't fully solve the problem.

What did solve the problem was going in to my system environment variables and looking at the PATH - I had uninstalled Python 3 but the old path to the Python 3 folder was still there. I'm running only Python 2 on my PC and used Python 2 to install pip.

Deleting the references to the nonexistent Python 3 folders from PATH in addition to upgrading to the latest version of pip fixed the issue.

GCD is a low-level C-based API that enables very simple use of a task-based concurrency model. NSOperation and NSOperationQueue are Objective-C classes that do a similar thing. NSOperation was introduced first, but as of 10.5 and iOS 2, NSOperationQueue and friends are internally implemented using GCD.

In general, you should use the highest level of abstraction that suits your needs. This means that you should usually use NSOperationQueue instead of GCD, unless you need to do something that NSOperationQueue doesn't support.

Note that NSOperationQueue isn't a "dumbed-down" version of GCD; in fact, there are many things that you can do very simply with NSOperationQueue that take a lot of work with pure GCD. (Examples: bandwidth-constrained queues that only run N operations at a time; establishing dependencies between operations. Both very simple with NSOperation, very difficult with GCD.) Apple's done the hard work of leveraging GCD to create a very nice object-friendly API with NSOperation. Take advantage of their work unless you have a reason not to.

Caveat: On the other hand, if you really just need to send off a block, and don't need any of the additional functionality that NSOperationQueue provides, there's nothing wrong with using GCD. Just be sure it's the right tool for the job.

The limit is dependent on both the server and the client used (and if applicable, also the proxy the server or the client is using).

Most web servers have a limit of 8192 bytes (8 KB), which is usually configurable somewhere in the server configuration. As to the client side matter, the HTTP 1.1 specification even warns about this. Here's an extract of chapter 3.2.1:

Note: Servers ought to be cautious about depending on URI lengths above 255 bytes, because some older client or proxy implementations might not properly support these lengths.

The limit in Internet Explorer and Safari is about 2 KB, in Opera about 4 KB and in Firefox about 8 KB. We may thus assume that 8 KB is the maximum possible length and that 2 KB is a more affordable length to rely on at the server side and that 255 bytes is the safest length to assume that the entire URL will come in.

If the limit is exceeded in either the browser or the server, most will just truncate the characters outside the limit without any warning. Some servers however may send an HTTP 414 error.

If you need to send large data, then better use POST instead of GET. Its limit is much higher, but more dependent on the server used than the client. Usually up to around 2 GB is allowed by the average web server.

This is also configurable somewhere in the server settings. The average server will display a server-specific error/exception when the POST limit is exceeded, usually as an HTTP 500 error.

1. An independent parent is the best practice for sharing configuration and options across otherwise uncoupled components. Apache has a parent pom project to share legal notices and some common packaging options.

2. If your top-level project has real work in it, such as aggregating javadoc or packaging a release, then you will have conflicts between the settings needed to do that work and the settings you want to share out via parent. A parent-only project avoids that.

3. A common pattern (ignoring #1 for the moment) is have the projects-with-code use a parent project as their parent, and have it use the top-level as a parent. This allows core things to be shared by all, but avoids the problem described in #2.

4. The site plugin will get very confused if the parent structure is not the same as the directory structure. If you want to build an aggregate site, you'll need to do some fiddling to get around this.

5. Apache CXF is an example the pattern in #2.

I'm an Android (and GUI) beginner, but have lots of experience with software. I've gone through a few of the tutorials, and this is my understanding:

layout_width and layout_height are attributes of the TextView. They are instructions for how the TextView should shape itself, they aren't referring to how to handle the content within the TextView.

If you use "fill_parent", you are saying that the TextView should shape itself relative to it's parent view, it should fill it.

If you use "wrap_content", you are saying that you should ignore the parent view, and let the contents of the TextView define it's shape.

I think this is the confusing point. "wrap_content" isn't telling the TextView how to manage it's contents (to wrap the lines), it's telling it that it should shape itself relative to it's contents. In this case, with no new line characters, it shapes itself so that all the text is on a single line (which unfortunately is overflowing the parent).

I think you want it to fill the parent horizontally, and to wrap it's contents vertically.

You can't if T is all you get. It must be injected by the provider:

Collection<T extends Comparable>

or pass in the Comparator

Collections.sort(...)

If you want to cast it to specific type (e.g. within tests) you can use ReadAsAsync extension method:

object yourTypeInstance = await response.Content.ReadAsAsync(typeof(YourType));

or following for synchronous code:

object yourTypeInstance = response.Content.ReadAsAsync(typeof(YourType)).Result;

Update: there is also generic option of ReadAsAsync<> which returns specific type instance instead of object-declared one:

YourType yourTypeInstance = await response.Content.ReadAsAsync<YourType>();

The best bet with these types of questions is to see exactly what python does. The dis module is incredibly informative:

>>> import dis
>>> dis.dis("val != None")
  1           0 LOAD_NAME                0 (val)
              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               3 (!=)
              6 RETURN_VALUE
>>> dis.dis("not (val is None)")
  1           0 LOAD_NAME                0 (val)
              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               9 (is not)
              6 RETURN_VALUE
>>> dis.dis("val is not None")
  1           0 LOAD_NAME                0 (val)
              2 LOAD_CONST               0 (None)
              4 COMPARE_OP               9 (is not)
              6 RETURN_VALUE

Notice that the last two cases reduce to the same sequence of operations, Python reads not (val is None) and uses the is not operator. The first uses the != operator when comparing with None.

As pointed out by other answers, using != when comparing with None is a bad idea.

Just make rdg2.nPhoneNumber varchar everywhere instead of int !

It worked well for me:

find directory_to_delete/ -type d -name '*.svn' | xargs rm -rf

As @kojiro said, you don't want to "run" this file. Source it as he says. It should get "sourced" at startup. Sourcing just means running every line in the file, including the one you want to get run. If you want to make sure a folder is in a certain path environment variable (as it seems you want from one of your comments on another solution), execute

$ echo $PATH

At the command line. If you want to check that your ~/.bash_profile is being sourced, either at startup as it should be, or when you source it manually, enter the following line into your ~/.bash_profile file:

$ echo "Hello I'm running stuff in the ~/.bash_profile!"

If the file that this script lives in is executable, the hash-bang (#!) tells the operating system what interpreter to use to run the script. In this case it's /bin/sh, for example.

There's a Wikipedia article about it for more information.

The following worked the best for me, basically I'm scrapping any existing tooltip and not bothering to show the new tooltip. If calling show on the tooltip like in other answers, it pops up even if the cursor isn't hovering above it.

The reason I went for this solution is that the other solutions, re-using the existing tooltip, led to some strange issues with the tooltip sometimes not showing when hovering the cursor above the element.

function updateTooltip(element, tooltip) {
    if (element.data('tooltip') != null) {
        element.tooltip('hide');
        element.removeData('tooltip');
    }
    element.tooltip({
        title: tooltip
    });
}

A much simpler solution would be to download the file using Chrome. In this manner you don't have to manually click on the save button.

using System;
using System.Diagnostics;
using System.ComponentModel;

namespace MyProcessSample
{
    class MyProcess
    {
        public static void Main()
        {
            Process myProcess = new Process();
            myProcess.Start("chrome.exe","http://www.com/newfile.zip");
        }
    }
}

Addition to @jwize's answer

Because angular.element(document).injector() was giving error injector is not defined So, I have created function that you can run after AJAX call or when DOM is changed using jQuery.

  function compileAngularElement( elSelector) {

        var elSelector = (typeof elSelector == 'string') ? elSelector : null ;  
            // The new element to be added
        if (elSelector != null ) {
            var $div = $( elSelector );

                // The parent of the new element
                var $target = $("[ng-app]");

              angular.element($target).injector().invoke(['$compile', function ($compile) {
                        var $scope = angular.element($target).scope();
                        $compile($div)($scope);
                        // Finally, refresh the watch expressions in the new element
                        $scope.$apply();
                    }]);
            }

        }

use it by passing just new element's selector. like this

compileAngularElement( '.user' ) ; 

A project can be referenced by multiple solutions.

Put your library or core code into one project, then reference that project in both solutions.

You could have the active class be dependent upon a boolean data value:

<th 
  class="initial " 
  v-on="click: myFilter"
  v-class="{active: isActive}">
  <span class="wkday">M</span>
</th>

new Vue({
  el: '#my-container',

  data: {
    isActive: false
  },

  methods: {
    myFilter: function() {
      this.isActive = !this.isActive;
      // some code to filter users
    }
  }
})

rt.jar contains all of the compiled class files for the base Java Runtime environment. You should not be messing with this jar file.

For MacOS it is called classes.jar and located under /System/Library/Frameworks/<java_version>/Classes . Same not messing with it rule applies there as well :).

As a general rule, there is not a specific 'uninstall' mechanism that comes with CPAN modules. But you might try make uninstall in the original directory the module unpacked into (this is often under /root/.cpan or ~/.cpan), as some packages do contain this directive in their install script. (However, since you've installed modules into a local (non-root) library directory, you also have the option of blowing away this entire directory and reinstalling everything else that you want to keep.)

A lot of the time you can simply get away with removing the A/B.pm file (for the A::B module) from your perllib -- that will at least render the module unusable. Most modules also contain a list of files to be installed (called a "manifest"), so if you can find that, you'll know which files you can delete.

However, none of these approaches will address any modules that were installed as dependencies. There's no good (automated) way of knowing if something else is dependent on that module, so you'll have to uninstall it manually as well once you're sure.

The difficulty in uninstalling modules is one reason why many Perl developers are moving towards using a revision control system to keep track of installations -- e.g. see the article by brian d foy as a supplement to his upcoming book that discusses using git for package management.

Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        Double d = scan.nextDouble();


        String newStr = "";
        Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
        while( charScanner.hasNext() ) { 
            String  c = charScanner.next();

            if (c.equalsIgnoreCase("\r")) {
                break;
            }
            else {
                newStr += c;    
            }
        }

        System.out.println("String: " + newStr);
        System.out.println("Int: " + i);
        System.out.println("Double: " + d);

This code works fine

If you use a unary plus to convert a string to a number as documented on MDN.

For example:+discount.toFixed(2)

You cannot set or read cookies on CORS requests through JavaScript. Although CORS allows cross-origin requests, the cookies are still subject to the browser's same-origin policy, which means only pages from the same origin can read/write the cookie. withCredentials only means that any cookies set by the remote host are sent to that remote host. You will have to set the cookie from the remote server by using the Set-Cookie header.

Adding in example for solution given earlier. By using socket.io-client https://github.com/socketio/socket.io-client

Client Side:

//client.js
var io = require('socket.io-client');
var socket = io.connect('http://localhost:3000', {reconnect: true});

// Add a connect listener
socket.on('connect', function (socket) {
    console.log('Connected!');
});
socket.emit('CH01', 'me', 'test msg');

Server Side :

//server.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

io.on('connection', function (socket){
   console.log('connection');

  socket.on('CH01', function (from, msg) {
    console.log('MSG', from, ' saying ', msg);
  });

});

http.listen(3000, function () {
  console.log('listening on *:3000');
});

Run :

Open 2 console and run node server.js and node client.js

Check this page out: http://matplotlib.org/examples/pylab_examples/subplots_demo.html

plt.subplots is similar. I think it's better since it's easier to set parameters of the figure. The first two arguments define the layout (in your case 1 row, 2 columns), and other parameters change features such as figure size:

import numpy as np
import matplotlib.pyplot as plt

x1 = np.linspace(0.0, 5.0)
x2 = np.linspace(0.0, 2.0)
y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
y2 = np.cos(2 * np.pi * x2)

fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(5, 3))
axes[0].plot(x1, y1)
axes[1].plot(x2, y2)
fig.tight_layout()

I think following can give broader coverage in fewer lines

import org.apache.commons.exec.OS;

if (OS.isFamilyWindows()){
                //load some property
            }
else if (OS.isFamilyUnix()){
                //load some other property
            }

the Correct Solution Would be like this

   QString k;
   k = "CRAZYYYQT";
   char ab[16];
   sprintf(ab,"%s",(const char *)((QByteArray)(k.toLatin1()).data()) );
   sprintf(ab,"%s",(const char *)((QByteArray)(k.toStdString()).data()));  
   sprintf(ab,"%s",(const char *)k.toStdString().c_str()  );
   qDebug()<<"--->"<<ab<<"<---";

I was able to get this somewhat working for C++ static_assert(). The wrinkle here is that static_assert() only accepts string literals; constexpr string_view will not work. You will need to accept extra text around the typename, but it works:

template<typename T>
constexpr void assertIfTestFailed()
{
#ifdef __clang__
    static_assert(testFn<T>(), "Test failed on this used type: " __PRETTY_FUNCTION__);
#elif defined(__GNUC__)
    static_assert(testFn<T>(), "Test failed on this used type: " __PRETTY_FUNCTION__);
#elif defined(_MSC_VER)
    static_assert(testFn<T>(), "Test failed on this used type: " __FUNCSIG__);
#else
    static_assert(testFn<T>(), "Test failed on this used type (see surrounding logged error for details).");
#endif
    }
}

MSVC Output:

error C2338: Test failed on this used type: void __cdecl assertIfTestFailed<class BadType>(void)
... continued trace of where the erroring code came from ...

Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.

So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.

cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit

But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.

@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit

Or if you'd like them to select the file from which to write in the batch you could do the following.

@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit

You should use the csv module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.

import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows([row[2:4] for _ in range(count)])

or, using the itertools module to do the repeating with itertools.repeat():

from itertools import repeat
import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows(repeat(row[2:4], count))

I had a routerLink="." attribute at one of my HTML tags which caused that error

Interesting idea. Some searching on Google produced a few pages of interest, including:

• an outline of how such a "jsonT" tool might be implemented, and some downloads
• some discussion of that implementation
• a company which may have implemented something suitable

Hope this helps.

You can do it via the constructor of your class:

public class foo {
  public foo(){
    Bar = "bar";
  }
  public string Bar {get;set;}
}

If you've got another constructor (ie, one that takes paramters) or a bunch of constructors you can always have this (called constructor chaining):

public class foo {
  private foo(){
    Bar = "bar";
    Baz = "baz";
  }
  public foo(int something) : this(){
    //do specialized initialization here
    Baz = string.Format("{0}Baz", something);
  }
  public string Bar {get; set;}
  public string Baz {get; set;}
}

If you always chain a call to the default constructor you can have all default property initialization set there. When chaining, the chained constructor will be called before the calling constructor so that your more specialized constructors will be able to set different defaults as applicable.

Try this:

#include <QDebug>
QString string;
// do things...
qDebug() << "right" << string << std::endl;

I also use smartassembly. However, I don't know how it works for a web application. However, I'd like to point out that if your app uses shareware type protection, make sure it don't check a license with a boolean return. it's too easy to byte crack. http://blogs.compdj.com/post/Binary-hack-a-NET-executable.aspx

The following works for me... S3 objects:

s3://bucket/
    form1/
       section11/

          file112
       section12/
          file121
    form2/
       section21/
          file211
          file112
       section22/
          file221
          file222
          ...
      ...
   ...

Using:

from boto3.session import Session
s3client = session.client('s3')
resp = s3client.list_objects(Bucket=bucket, Prefix='', Delimiter="/")
forms = [x['Prefix'] for x in resp['CommonPrefixes']] 

we get:

form1/
form2/
...

With:

resp = s3client.list_objects(Bucket=bucket, Prefix='form1/', Delimiter="/")
sections = [x['Prefix'] for x in resp['CommonPrefixes']] 

we get:

form1/section11/
form1/section12/

may be problem in data binding in export excel . check that data properly bin to a gridview or not.

Use this code for export grid view in excel sheet and note that you must add iTextSharp dll in you project.

        Response.Clear();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.xls");

        GridView1.AllowPaging = false;

        // Re-Bind data to GridView 

        using (CompMSEntities1 CompObj = new CompMSEntities1())
        {
            Start = Convert.ToDateTime(txtStart.Text);
            End = Convert.ToDateTime(txtEnd.Text);

        //Change the Header Row back to white color

        GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");


       GridView1.Style.Add(" font-size", "10px");

Your list just contains a string. Convert it to integer IDs:

L = ['350882 348521 350166\r\n']

ids = [int(i) for i in L[0].strip().split()]
print(ids)
id = 348521
if id not in ids:
    ids.append(id)
print(ids)
id = 348522
if id not in ids:
    ids.append(id)
print(ids)
# Turn it back into your odd format
L = [' '.join(str(id) for id in ids) + '\r\n']
print(L)

Output:

[350882, 348521, 350166]
[350882, 348521, 350166]
[350882, 348521, 350166, 348522]
['350882 348521 350166 348522\r\n']

Edit: The original answer suggested the use of df.ix[:,2] but this function is now deprecated. Users should switch to df.iloc[:,2].

Unfortunately, I don't believe there really is a better way of doing this due to the nature of Java's handling of primitive types, boxing, arrays and generics. In particular:

• List<T>.toArray won't work because there's no conversion from Integer to int
• You can't use int as a type argument for generics, so it would have to be an int-specific method (or one which used reflection to do nasty trickery).

I believe there are libraries which have autogenerated versions of this kind of method for all the primitive types (i.e. there's a template which is copied for each type). It's ugly, but that's the way it is I'm afraid :(

Even though the Arrays class came out before generics arrived in Java, it would still have to include all the horrible overloads if it were introduced today (assuming you want to use primitive arrays).

How to find out the document width and height very easily?

in HTML
<span id="hidden_placer" style="position:absolute;right:0;bottom:0;visibility:hidden;"></span>

in javascript

     var c=document.querySelector('#hidden_placer');

     var r=c.getBoundingClientRect();
     r.right=document width
     r.bottom=document height`

You may update this on every window resize event, if needed.

I was getting this problem while using a tunnel because I:

2. but was accessing the local server by pointing my browser to "http://localhost:3000"

once i started punching the tunnel url:port into the browser, i was good to go.

Use the set_facecolor(color) method of the axes object, which you've created one of the following ways:

• You created a figure and axis/es together

  fig, ax = plt.subplots(nrows=1, ncols=1)
  

• You created a figure, then axis/es later

  fig = plt.figure()
  ax = fig.add_subplot(1, 1, 1) # nrows, ncols, index
  

• You used the stateful API (if you're doing anything more than a few lines, and especially if you have multiple plots, the object-oriented methods above make life easier because you can refer to specific figures, plot on certain axes, and customize either)

  plt.plot(...)
  ax = plt.gca()
  

Then you can use set_facecolor:

ax.set_facecolor('xkcd:salmon')
ax.set_facecolor((1.0, 0.47, 0.42))

As a refresher for what colors can be:

matplotlib.colors

Matplotlib recognizes the following formats to specify a color:

• an RGB or RGBA tuple of float values in [0, 1] (e.g., (0.1, 0.2, 0.5) or (0.1, 0.2, 0.5, 0.3));
• a hex RGB or RGBA string (e.g., '#0F0F0F' or '#0F0F0F0F');
• a string representation of a float value in [0, 1] inclusive for gray level (e.g., '0.5');
• one of {'b', 'g', 'r', 'c', 'm', 'y', 'k', 'w'};
• a X11/CSS4 color name;
• a name from the xkcd color survey; prefixed with 'xkcd:' (e.g., 'xkcd:sky blue');
• one of {'tab:blue', 'tab:orange', 'tab:green', 'tab:red', 'tab:purple', 'tab:brown', 'tab:pink', 'tab:gray', 'tab:olive', 'tab:cyan'} which are the Tableau Colors from the ‘T10’ categorical palette (which is the default color cycle);
• a “CN” color spec, i.e. 'C' followed by a single digit, which is an index into the default property cycle (matplotlib.rcParams['axes.prop_cycle']); the indexing occurs at artist creation time and defaults to black if the cycle does not include color.

All string specifications of color, other than “CN”, are case-insensitive.

Now dstat provides the feature to find out in your running system which process is candidate for getting killed by oom mechanism

dstat --top-oom
 --out-of-memory---
  kill score
 java           77
 java           77
 java           77

and as per man page

  --top-oom
          show process that will be killed by OOM the first

This is the shortest version I could find,saving/hiding an extra conversion:

pil_image = PIL.Image.open('image.jpg')
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

If reading a file from a URL:

import cStringIO
import urllib
file = cStringIO.StringIO(urllib.urlopen(r'http://stackoverflow.com/a_nice_image.jpg').read())
pil_image = PIL.Image.open(file)
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

It's the Return or Enter key on keyboard.

I answer to myself. As suggested by Vadzim, I must consider the jboss-logging.xml file and insert these lines:

<logger category="org.hibernate">
     <level name="TRACE"/>
</logger>

Instead of DEBUG level I wrote TRACE. Now don't look only the console but open the server.log file (debug messages aren't sent to the console but you can configure this mode!).

Regarding tables names, case, etc, the prevalent convention is:

• SQL keywords: UPPER CASE
• names (identifiers): lower_case_with_underscores

For example:

UPDATE my_table SET name = 5;

This is not written in stone, but the bit about identifiers in lower case is highly recommended, IMO. Postgresql treats identifiers case insensitively when not quoted (it actually folds them to lowercase internally), and case sensitively when quoted; many people are not aware of this idiosyncrasy. Using always lowercase you are safe. Anyway, it's acceptable to use camelCase or PascalCase (or UPPER_CASE), as long as you are consistent: either quote identifiers always or never (and this includes the schema creation!).

I am not aware of many more conventions or style guides. Surrogate keys are normally made from a sequence (usually with the serial macro), it would be convenient to stick to that naming for those sequences if you create them by hand (tablename_colname_seq).

See also some discussion here, here and (for general SQL) here, all with several related links.

Note: Postgresql 10 introduced identity columns as an SQL-compliant replacement for serial.

This is relatively simple if you use pylab (included with matplotlib) instead of matplotlib directly. Start off with a list of filenames and legend names, like [ ('name of file 1', 'label 1'), ('name of file 2', 'label 2'), ...]. Then you can use something like the following:

import pylab

datalist = [ ( pylab.loadtxt(filename), label ) for filename, label in list_of_files ]

for data, label in datalist:
    pylab.plot( data[:,0], data[:,1], label=label )

pylab.legend()
pylab.title("Title of Plot")
pylab.xlabel("X Axis Label")
pylab.ylabel("Y Axis Label")

You also might want to add something like fmt='o' to the plot command, in order to change from a line to points. By default, matplotlib with pylab plots onto the same figure without clearing it, so you can just run the plot command multiple times.

I've just found this solution:

if(@getimagesize($remoteImageURL)){
    //image exists!
}else{
    //image does not exist.
}

    -moz-background-size: cover;
    -o-background-size: cover;

I think it is fine because I've seen many people doing this way.

If you are just defining the event handler within the directive, you do not have to define it on the scope, though. Following would be fine.

myApp.directive('clickme', function() {
  return function(scope, element, attrs) {
    var clickingCallback = function() {
      alert('clicked!')
    };
    element.bind('click', clickingCallback);
  }
});

As you know the display property cannot be animated BUT just by having it in your CSS it overrides the visibility and opacity transitions.

I have a sheet that is made to used by others and I have quite a few indirect() references around, so I need to formulaically handle a changed sheet tab name.

I used the formula from JohnP2 (below) but was having trouble because it didn't update automatically when a sheet name was changed. You need to go to the actual formula, make an arbitrary change and refresh to run it again.

=REGEXREPLACE(CELL("address",'SHEET NAME'!A1),"'?([^']+)'?!.*","$1")

I solved this by using info found in this solution on how to force a function to refresh. It may not be the most elegant solution, but it forced Sheets to pay attention to this cell and update it regularly, so that it catches an updated sheet title.

=IF(TODAY()=TODAY(), REGEXREPLACE(CELL("address",'SHEET NAME'!A1),"'?([^']+)'?!.*","$1"), "")

Using this, Sheets know to refresh this cell every time you make a change, which results in the address being updated whenever it gets renamed by a user.

// timestamp to Date
long timestamp = 5607059900000; //Example -> in ms
Date d = new Date(timestamp );

// Date to timestamp
long timestamp = d.getTime();

//If you want the current timestamp :
Calendar c = Calendar.getInstance();
long timestamp = c.getTimeInMillis();

I am not sure if previous versions of pandas prevented this but now the following snippet works perfectly for me and produces exactly what you want without having to use apply

>>> import pandas as pd
>>> from sklearn.preprocessing import MinMaxScaler


>>> scaler = MinMaxScaler()

>>> dfTest = pd.DataFrame({'A':[14.00,90.20,90.95,96.27,91.21],
                           'B':[103.02,107.26,110.35,114.23,114.68],
                           'C':['big','small','big','small','small']})

>>> dfTest[['A', 'B']] = scaler.fit_transform(dfTest[['A', 'B']])

>>> dfTest
          A         B      C
0  0.000000  0.000000    big
1  0.926219  0.363636  small
2  0.935335  0.628645    big
3  1.000000  0.961407  small
4  0.938495  1.000000  small

if(!preg_match('/^[\w-]+$/', $string1)) {
   echo "String 1 not acceptable acceptable";
   // String2 acceptable
}

For a method that works with both C and C++, you might want to consider using the standard library function strtol().

#include <cstdlib>
#include <iostream>
using namespace std;

int main() {
    string s = "abcd";
    char * p;
    long n = strtol( s.c_str(), & p, 16 );
    if ( * p != 0 ) { //my bad edit was here
        cout << "not a number" << endl;
    }
    else {
        cout << n << endl;
    }
}

ls -R -L

-L dereferences symbolic links. This will also make it impossible to see any symlinks to files, though - they'll look like the pointed-to file.

    Intent notificationIntent = new Intent(context, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context,0,notificationIntent,0);

AskTom is probably the single most helpful resource on best practices on Oracle DBs. (I usually just type "asktom" as the first word of a google query on a particular topic)

I don't think it's really appropriate to speak of design patterns with relational databases. Relational databases are already the application of a "design pattern" to a problem (the problem being "how to represent, store and work with data while maintaining its integrity", and the design being the relational model). Other approches (generally considered obsolete) are the Navigational and Hierarchical models (and I'm nure many others exist).

Having said that, you might consider "Data Warehousing" as a somewhat separate "pattern" or approach in database design. In particular, you might be interested in reading about the Star schema.

=SUMPRODUCT((A1:A5="FRANCE")*B1:D5)

Try if that works

sc = spark.sparkContext

# Infer the schema, and register the DataFrame as a table.
schemaPeople = spark.createDataFrame(RddName)
schemaPeople.createOrReplaceTempView("RddName")

Why not just simplify it to if($_GET['id']). It will return true or false depending on status of the parameter's existence.

Here is a sample to find if there are match elements in another list

List<int> nums1 = new List<int> { 2, 4, 6, 8, 10 };
List<int> nums2 = new List<int> { 1, 3, 6, 9, 12};

if (nums1.Any(x => nums2.Any(y => y == x)))
{
    Console.WriteLine("There are equal elements");
}
else
{
    Console.WriteLine("No Match Found!");
}

Run this in the CMD shell or batch file:

FC file1 file2

FC can also be used to compare binary files:

FC /B file1 file2

you can run this query

SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%%' --if you want to find specific column write here 
ORDER BY schema_name, table_name;

If you're willing to use a different javascript library, numeral.js can format seconds as follows (example is for 1000 seconds):

var string = numeral(1000).format('00:00');
// '00:16:40'

String mQuery = "SELECT Name,Family From tblName";
Cursor mCur = db.rawQuery(mQuery, new String[]{});
mCur.moveToFirst();
while ( !mCur.isAfterLast()) {
        String name= mCur.getString(mCur.getColumnIndex("Name"));
        String family= mCur.getString(mCur.getColumnIndex("Family"));
        mCur.moveToNext();
}

Name and family are your result

   <input type="text" name="profileChildCount" id="profileChildCount" ng-model="profile.ChildCount" numeric-only maxlength="1" />

you can use numeric-only attribute .

This should work for MVC3 & MVC4

 @Html.TextBoxFor(m => m.Age, new { @Value = "12" }) 

If you want it to be a hidden field

 @Html.TextBoxFor(m => m.Age, new { @Value = "12",@type="hidden" }) 

/C Carries out the command specified by the string and then terminates.

You can get all the cmd command line switches by typing cmd /?.

if you wanna ng-model value, if you can write like this in the triggered event: $scope.searchText

TLDR

undefined is a primitive value in JavaScript that indicates the implicit absence of a value. Uninitialized variables automatically have this value, and functions without an explicit return statement, return undefined.

null is also a primitive value in JavaScript. It indicates the intentional absence of an object value. null in JavaScript was designed to enable interoperability with Java.

typeof null returns "object" because of a peculiarity in the design of the language, stemming from the demand that JavaScript be interoperable with Java. It does not mean null is an instance of an object. It means: given the tree of primitive types in JavaScript, null is part of the "object-type primitive" subtree. This is explained more fully below.

Details

undefined is a primitive value that represents the implicit absence of a value. Note that undefined was not directly accessible until JavaScript 1.3 in 1998. This tells us that null was intended to be the value used by programmers when explicitly indicating the absence of a value. Uninitialized variables automatically have the value undefined. undefined is a one-of-a-kind type in the ECMAScript specification.

null is a primitive value that represents the intentional absence of an object value. null is also a one-of-a-kind type in the ECMAScript specification.

null in JavaScript was designed with a view to enable interoperability with Java, both from a "look" perspective, and from a programatic perspective (eg the LiveConnect Java/JS bridge planned for 1996). Both Brendan Eich and others have since expressed distaste at the inclusion of two "absence of value" values, but in 1995 Eich was under orders to "make [JavaScript] look like Java".

Brendan Eich:

If I didn't have "Make it look like Java" as an order from management, and I had more time (hard to unconfound these two causal factors), then I would have preferred a Self-like "everything's an object" approach: no Boolean, Number, String wrappers. No undefined and null. Sigh.

In order to accommodate Java's concept of null which, due to the strongly-typed nature of Java, can only be assigned to variables typed to a reference type (rather primitives), Eich chose to position the special null value at the top of the object prototype chain (ie. the top of the reference types), and to include the null type as part of the set of "object-type primitives".

The typeof operator was added shortly thereafter in JavaScript 1.1, released on 19th August 1996.

From the V8 blog:

typeof null returns object, and not null, despite null being a type of its own. To understand why, consider that the set of all JavaScript types is divided into two groups:

1. objects (i.e. the Object type)
2. primitives (i.e. any non-object value)

As such, null means “no object value”, whereas undefined means “no value”.

Following this line of thought, Brendan Eich designed JavaScript to make typeof return 'object' for all values on the right-hand side, i.e. all objects and null values, in the spirit of Java. That’s why typeof null === 'object' despite the spec having a separate null type.

So Eich designed the heirarchy of primitive types to enable interoperability with Java. This led to him positioning null along with the "object-type primitives" on the heirarchy. To refelct this, when typeof was added to the language shortly thereafter, he chose typeof null to return "object".

The surprise expressed by JavaScript developers at typeof null === "object" is the result of an impedance mismatch (or abstraction leak) between a weakly-typed language (JavaScript) that has both null and undefined, and another, strongly-typed language (Java) that only has null, and in which null is strictly defined to refer to a reference type (not a primitive type).

Note that this is all logical, reasonable and defensible. typeof null === "object" is not a bug, but a second-order effect of having to accommodate Java interoperability.

A number of imperfect backwards rationalisations and/or conventions have emerged, including that undefined indicates implicit absence of a value, and that null indicates intentional absence of a value; or that undefined is the absence of a value, and null is specifically the absence of an object value.

A relevant conversation with Brendan Eich, screenshotted for posterity:

The command is date

To customise the output there are a myriad of options available, see date --help for a list.

For example, date '+%A %W %Y %X' gives Tuesday 34 2013 08:04:22 which is the name of the day of the week, the week number, the year and the time.

I use a script which redirects the user from index.html to relative url of Login Page

<html>
  <head>
    <title>index.html</title>

  <body onload="document.getElementById('lnkhome').click();">
    <a href="/Pages/Login.aspx" id="lnkhome">Go to Login Page<a>
  </body>
</html>

I have read multiple threads and none of them fixed the issue that people are describing and I have experienced too.

I have even tried to move away from conda and use pip, to upgrade to python 3.7, i have tried all coding proposed and none of them fixed.

And here is why (the problem):

by default python/flask search the static and the template in a folder structure like:

/Users/username/folder_one/folder_two/ProjectName/src/app_name/<static>
 and 
/Users/username/folder_one/folder_two/ProjectName/src/app_name/<template>

you can verify by yourself using the debugger on Pycharm (or anything else) and check the values on the app (app = Flask(name)) and search for teamplate_folder and static_folder

in order to fix this, you have to specify the values when creating the app something like this:

TEMPLATE_DIR = os.path.abspath('../templates')
STATIC_DIR = os.path.abspath('../static')

# app = Flask(__name__) # to make the app run without any
app = Flask(__name__, template_folder=TEMPLATE_DIR, static_folder=STATIC_DIR)

the path TEMPLATE_DIR and STATIC_DIR depend on where the file app is located. in my case, see the picture, it was located within a folder under src.

you can change the template and static folders as you wish and register on the app = Flask...

In truth, I have started experiencing the problem when messing around with folder and at times worked at times not. this fixes the problem once and for all

the html code looks like this:

<link href="{{ url_for('static', filename='libraries/css/bootstrap.css') }}" rel="stylesheet" type="text/css" >

This the code

Here the structure of the folders

The stack has a space limit that depends on the OS, the normal size is 8MB (In Ubuntu, you can check that limit with $ ulimit -u and it can be checked in other OS similarly). Any program make use of the stack at runtime, but to fully know when it is used you need to check an Assembly language. In x86_64 for example, the stack is used to:

1. Save returning address when making a procedure call
2. Save local variables
3. Save special registers to restore them later
4. Pass arguments to a procedure call (more than 6)
5. Other: random unused stack base, canary values, padding, ... etc

If you don't know x86_64 (normal case) you only need to know when the specific high-lvl programming language you are using compile to those actions. For example in C:

• (1) ? a function call
• (2) ? local variables in function calls (including main)
• (3) ? local variables in function calls (not main)
• (4) ? a function call
• (5) ? normally a function call, it is generally irrelevant for a stack overflow.

So, in C, only local variables and function calls make use of the stack. The 2 (unique?) ways of making a stack overflow are:

• Declaring too large local variables in main or in any function that its called (int array[10000][10000];)
• A very deep or infinite recursion (too many function calls at the same time).

To avoid a StackOverflowError you can :

• check if local variables are too big (order of 1 MB) ? use the heap (malloc/calloc calls) or global variables.

• check for infinite recursion ? you know what to do... correct it!

• check for normal too deep recursion ? the easiest approach is to just change the implementation to be iterative.

Notice also that global variables, include libraries, etc... don't make use of the stack.

Only if the above does not work, change the stack size to the maximum on the specific OS. With Ubuntu for example: $ ulimit -s 32768 (32 MB). (This has never been the solution for any of my stack overflow errors, but I also don't have much experience)

I have omitted special and/or not standard cases in C (such as usage of alloc() and similar) because if you are using them you should already know exactly what you are doing.

Cheers!

Please read the $.ajax documentation, this is a covered topic.

$.ajax({
    url: "test.html",
    error: function(){
        // will fire when timeout is reached
    },
    success: function(){
        //do something
    },
    timeout: 3000 // sets timeout to 3 seconds
});

You can get see what type of error was thrown by accessing the textStatus parameter of the error: function(jqXHR, textStatus, errorThrown) option. The options are "timeout", "error", "abort", and "parsererror".

While many of these solutions have worked for me in the past, they all failed me today on a Mac with a Samsung S7. After trying a few cables, someone suggested that the ADB connection requires an official Samsung cable to work. Indeed, when I used the Samsung cable, ADB worked just fine. I hope this helps someone else!

Round tripping dates through strings has always been a pain...but the docs to indicate that the 'o' specifier is the one to use for round tripping which captures the UTC state. When parsed the result will usually have Kind == Utc if the original was UTC. I've found that the best thing to do is always normalize dates to either UTC or local prior to serializing then instruct the parser on which normalization you've chosen.

DateTime now = DateTime.Now;
DateTime utcNow = now.ToUniversalTime();

string nowStr = now.ToString( "o" );
string utcNowStr = utcNow.ToString( "o" );

now = DateTime.Parse( nowStr );
utcNow = DateTime.Parse( nowStr, null, DateTimeStyles.AdjustToUniversal );

Debug.Assert( now == utcNow );

I've used OAuth a few times, and also used some other methods (BASIC/DIGEST). I wholeheartedly suggest OAuth. The following link is the best tutorial I've seen on using OAuth:

Use -qscale:v to control quality

Use -qscale:v (or the alias -q:v) as an output option.

• Normal range for JPEG is 2-31 with 31 being the worst quality.
• The scale is linear with double the qscale being roughly half the bitrate.
• Recommend trying values of 2-5.
• You can use a value of 1 but you must add the -qmin 1 output option (because the default is -qmin 2).

To output a series of images:

ffmpeg -i input.mp4 -qscale:v 2 output_%03d.jpg

See the image muxer documentation for more options involving image outputs.

To output a single image at ~60 seconds duration:

ffmpeg -ss 60 -i input.mp4 -qscale:v 4 -frames:v 1 output.jpg

For the past few years I have been using Ian Lance Taylor's libbacktrace. It is much cleaner than the functions in the GNU C library which require exporting all the symbols. It provides more utility for the generation of backtraces than libunwind. And last but not least, it is not defeated by ASLR as are approaches requiring external tools such as addr2line.

Libbacktrace was initially part of the GCC distribution, but it is now made available by the author as a standalone library under a BSD license:

https://github.com/ianlancetaylor/libbacktrace

At the time of writing, I would not use anything else unless I need to generate backtraces on a platform which is not supported by libbacktrace.

Removing a Single Attribute on a Single File

See Bavarious's answer.

To Remove All Extended Attributes On a Single File

Use xattr with the -c flag to "clear" the attributes:

xattr -c yourfile.txt

To Remove All Extended Attributes On Many Files

To recursively remove extended attributes on all files in a directory, combine the -c "clear" flag with the -r recursive flag:

xattr -rc /path/to/directory

A Tip for Mac OS X Users

Have a long path with spaces or special characters?

Open Terminal.app and start typing xattr -rc, include a trailing space, and then then drag the file or folder to the Terminal.app window and it will automatically add the full path with proper escaping.

You can also set a Constraint on a Table with the KEY fields and set On Conflict "Ignore"

When an applicable constraint violation occurs, the IGNORE resolution algorithm skips the one row that contains the constraint violation and continues processing subsequent rows of the SQL statement as if nothing went wrong. Other rows before and after the row that contained the constraint violation are inserted or updated normally. No error is returned when the IGNORE conflict resolution algorithm is used.

I would rather use the following class to generate random numbers:

System.Security.Cryptography.RNGCryptoServiceProvider prov = new System.Security.Cryptography.RNGCryptoServiceProvider();
prov.GetBytes(random);

If you want to resize an image after it is loaded, you can attach to the onload event of the <img> tag. Note that it may not be supported in all browsers (Microsoft's reference claims it is part of the HTML 4.0 spec, but the HTML 4.0 spec doesn't list the onload event for <img>).

The code below is tested and working in: IE 6, 7 & 8, Firefox 2, 3 & 3.5, Opera 9 & 10, Safari 3 & 4 and Google Chrome:

<img src="yourImage.jpg" border="0" height="real_height" width="real_width"
    onload="resizeImg(this, 200, 100);">

<script type="text/javascript">
function resizeImg(img, height, width) {
    img.height = height;
    img.width = width;
}
</script>

Use the following code if you want to select an option with a specific value:

$('select>option[value="' + value + '"]').prop('selected', true);

You can also closure array with replacements like this.

var url = '/getElement/_/_/_'.replace(/_/g, (_ => this.ar[this.i++]).bind({ar: ["invoice", "id", 1337],i: 0}))
> '/getElement/invoice/id/1337

or you can try bind

'/getElement/_/_/_'.replace(/_/g, (function(_) {return this.ar[this.i++];}).bind({ar: ["invoice", "id", 1337],i: 0}))

ALTER TABLE MyTable MODIFY Col3 varchar(20) NULL;

Use select setval('payments_id_seq', 21, true);

setval contains 3 parameters:

• 1st parameter is sequence_name
• 2nd parameter is Next nextval
• 3rd parameter is optional.

The use of true or false in 3rd parameter of setval is as follows:

SELECT setval('payments_id_seq', 21);           // Next nextval will return 22
SELECT setval('payments_id_seq', 21, true);     // Same as above 
SELECT setval('payments_id_seq', 21, false);    // Next nextval will return 21

The better way to avoid hard-coding of sequence name, next sequence value and to handle empty column table correctly, you can use the below way:

SELECT setval(pg_get_serial_sequence('table_name', 'id'), coalesce(max(id), 0)+1 , false) FROM table_name;

where table_name is the name of the table, id is the primary key of the table

From Python 2.5 onwards you can do:

value = b if a > 10 else c

Previously you would have to do something like the following, although the semantics isn't identical as the short circuiting effect is lost:

value = [c, b][a > 10]

There's also another hack using 'and ... or' but it's best to not use it as it has an undesirable behaviour in some situations that can lead to a hard to find bug. I won't even write the hack here as I think it's best not to use it, but you can read about it on Wikipedia if you want.

The other already explained to you that the syntax that you observe is called "constructor initializer list". This syntax lets you to custom-initialize base subobjects and member subobjects of the class (as opposed to allowing them to default-initialize or to remain uninitialized).

I just want to note that the syntax that, as you said, "looks like a constructor call", is not necessarily a constructor call. In C++ language the () syntax is just one standard form of initialization syntax. It is interpreted differently for different types. For class types with user-defined constructor it means one thing (it is indeed a constructor call), for class types without user-defined constructor it means another thing (so called value initialization ) for empty ()) and for non-class types it again means something different (since non-class types have no constructors).

In your case the data member has type int. int is not a class type, so it has no constructor. For type int this syntax means simply "initialize bar with the value of num" and that's it. It is done just like that, directly, no constructors involved, since, once again, int is not a class type of therefore it can't have any constructors.

If you use Mercurial, you can use the built in HTTP server. In the folder you wish to serve up:

hg serve

From the docs:

export the repository via HTTP

    Start a local HTTP repository browser and pull server.

    By default, the server logs accesses to stdout and errors to
    stderr. Use the "-A" and "-E" options to log to files.

options:

 -A --accesslog       name of access log file to write to
 -d --daemon          run server in background

If you are running PHP on Apache then you can use the enviroment variable called DOCUMENT_ROOT. This means that the path is dynamic, and can be moved between servers without messing about with the code.

<?php
  $fileLocation = getenv("DOCUMENT_ROOT") . "/myfile.txt";
  $file = fopen($fileLocation,"w");
  $content = "Your text here";
  fwrite($file,$content);
  fclose($file);
?>

Maybe it's because of duplicate Activity declaration in your manifest.

It's same as vikasdumca's steps, but thought to share the link.

run the following command

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

then

sudo apt-get install oracle-java8-installer

this would install oracle java 8 on ubuntu properly.

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

No need for a StringBuilder:

string path = @"c:\hereIAm.txt";
if (!File.Exists(path)) 
{
    // Create a file to write to.
    using (StreamWriter sw = File.CreateText(path)) 
    {
        sw.WriteLine("Here");
        sw.WriteLine("I");
        sw.WriteLine("am.");
    }    
} 

But of course you can use the StringBuilder to create all lines and write them to the file at once.

sw.Write(stringBuilder.ToString());

I also tried to make an executable jar file that I could run with the following command:

java -jar <jarfile>

After some searching I found the following link:

Packaging and Deploying Desktop Java Applications

I set the project's main class:

1. Right-click the project's node and choose Properties
2. Select the Run panel and enter the main class in the Main Class field
3. Click OK to close the Project Properties dialog box
4. Clean and build project

Then in the fodler dist the newly created jar should be executable with the command I mentioned above.

Use:

https://wa.me/YOURNUMBER

where YOURNUMBER is without the two leading 00.

For instance for +37061204312 you write:

https://wa.me/37061204312

This link seems to work on mobiles and on desktop computers.

To prefill the message with text you can use:

https://wa.me/YOURNUMBER/?text=urlencodedtext

Use node.js for that, here is example how to install node by using brew on mac:

brew update && install node

Then run your program by typing node filename.js, and you can use console.log() for output.

Keeping the aspect ratio,

  public Bitmap resizeBitmap(Bitmap source, int width,int height) {
    if(source.getHeight() == height && source.getWidth() == width) return source;
    int maxLength=Math.min(width,height);
    try {
        source=source.copy(source.getConfig(),true);
        if (source.getHeight() <= source.getWidth()) {
            if (source.getHeight() <= maxLength) { // if image already smaller than the required height
                return source;
            }

            double aspectRatio = (double) source.getWidth() / (double) source.getHeight();
            int targetWidth = (int) (maxLength * aspectRatio);

            return Bitmap.createScaledBitmap(source, targetWidth, maxLength, false);
        } else {

            if (source.getWidth() <= maxLength) { // if image already smaller than the required height
                return source;
            }

            double aspectRatio = ((double) source.getHeight()) / ((double) source.getWidth());
            int targetHeight = (int) (maxLength * aspectRatio);

            return Bitmap.createScaledBitmap(source, maxLength, targetHeight, false);

        }
    }
    catch (Exception e)
    {
        return source;
    }
}

I always used a couple lines of code which clear the input stream of any characters and then wait for input to ignore.

Something like:

void pause() {
    cin.clear();
    cout << endl << "Press any key to continue...";
    cin.ignore();
}

And then any time I need it in the program I have my own pause(); function, without the overhead of a system pause. This is only really an issue when writing console programs that you want to stay open or stay fixated on a certain point though.

The latest version of angular is only setup for evergreen browsers by default...

The current setup is for so-called "evergreen" browsers; the last versions of browsers that automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera), Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
This also includes firefox, although not mentioned.

See here for more information on browser support along with a list of suggested polyfills for specific browsers. https://angular.io/guide/browser-support#polyfill-libs

To achieve this, go into polyfills.ts (in the src folder by default) and just uncomment the following imports:

/***************************************************************************************************
 * BROWSER POLYFILLS
 */

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
 import 'core-js/es6/symbol';
 import 'core-js/es6/object';
 import 'core-js/es6/function';
 import 'core-js/es6/parse-int';
 import 'core-js/es6/parse-float';
 import 'core-js/es6/number';
 import 'core-js/es6/math';
 import 'core-js/es6/string';
 import 'core-js/es6/date';
 import 'core-js/es6/array';
 import 'core-js/es6/regexp';
 import 'core-js/es6/map';
 import 'core-js/es6/set';

Note that the comment is literally in the file, so this is easy to find.

If you are still having issues, you can downgrade the target property to es5 in tsconfig.json as @MikeDub suggested. What this does is change the compilation output of any es6 definitions to es5 definitions. For example, fat arrow functions (()=>{}) will be compiled to anonymous functions (function(){}). You can find a list of es6 supported browsers here.

Notes

• I was asked in the comments by @jackOfAll whether IE11 polyfills are loaded even if the user is in an evergreen browser which doesn't need them. The answer is, yes they are! The inclusion of the IE11 polyfills will take your polyfill file from ~162KB to ~258KB as of Aug 8 '17. I have invested in trying to solve this however it does not seem possible at this time.

• If you are getting errors in IE10 and below, go into you package.json and downgrade webpack-dev-server to 2.7.1 specifically. Versions higher than this no longer support "older" IE versions.

Some of more advanced Oracle database features such as session trace do not work properly in Oracle 11g XE 32-bit if installed on Windows 64-bit system. I needed session trace on Windows 7 64-bit.

Apart from that it works well for me in multiple production MS Windows 64-bit systems: Windows Server 2008 R2 and Windows Server 2003 R2.

you should not do JSON.stringify(data) while sending through AJAX like below.

This is NOT correct code:

function callAjax(url, data) {
    $.ajax({
        url: url,
        type: "POST",
        data: JSON.stringify(data),
        success: function(d) {
            alert("successs "+ JSON.stringify(d));
        }
    });
}   

The correct code is:

function callAjax(url, data) {
    $.ajax({
        url: url,
        type: "POST",
        data: data,
        success: function(d) {
            alert("successs "+ JSON.stringify(d));
        }
    });
}

Instead of working with positioning and padding/margin and without knowing the header's size, there's a way to keep the header fixed by playing with the scroll.

See the this plunker with a fixed header:

<html lang="en" style="height: 100%">
<body style="height: 100%">
<div style="height: 100%; overflow: hidden">
  <div>Header</div>
  <div style="height: 100%; overflow: scroll">Content - very long Content...

The key here is a mix of height: 100% with overflow.

See a specific question on removing the scroll from the header here and answer here.

Using ImageMagick, this is very similar to hackerb9 code and result, but is a little simpler command line. It does assume that the top left pixel is the background color. I just flood fill the background with transparency, then select the alpha channel and blur it and remove half of the blurred area using -level 50x100%. Then turn back on all the channels and flatten it against the brown color. The -blur 0x1 -level 50x100% acts to antialias the boundaries of the alpha channel transparency. You can adjust the fuzz value, blur amount and the -level 50% value to change the degree of antialiasing.

convert logo: -fuzz 25% -fill none -draw "matte 0,0 floodfill" -channel alpha -blur 0x1 -level 50x100% +channel -background saddlebrown -flatten result.jpg

Use This way is Better

if LEN(ISNULL(@Value,''))=0              

This check the field is empty or NULL

If you simply want to initialise a member field or property with the constructor parameter, in C# >= 3 you can do it very easier:

public static string GetAllItems<T>(...) where T : InterfaceOrBaseClass, new() 
{ 
   ... 
   List<T> tabListItems = new List<T>(); 
   foreach (ListItem listItem in listCollection)  
   { 
       tabListItems.Add(new T{ BaseMemberItem = listItem }); // No error, BaseMemberItem owns to InterfaceOrBaseClass. 
   }  
   ... 
} 

This is the same thing Garry Shutler said, but I'd like to put an aditional note.

Of course you can use a property trick to do more stuff than just setting a field value. A property "set()" can trigger any processing needed to setup its related fields and any other need for the object itself, including a check to see if a full initialization is to take place before the object is used, simulating a full contruction (yes, it is an ugly workaround, but it overcomes M$'s new() limitation).

I can't be assure if it is a planned hole or an accidental side effect, but it works.

It is very funny how MS people adds new features to the language and seems to not do a full side effects analysis. The entire generic thing is a good evidence of this...

I got the same problem. I was sure that it was due to very small fault and yes it was!

I found the solution:

When generating the debug hash key in my computer, I entered the password of my system. But the password should be the following -

Enter keystore password: "android". This was the only problem in my case.

----- For generating Debug key hash, use this command -

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

Enter keystore password: 'android'

----- To Generate Release key hash, use this command -

keytool -exportcert -alias "alias of keystore" -keystore "Your path to the keystore when signing app" | openssl sha1 -binary | openssl base64

Provide your keystore password after executing this command.

Upon installing .NET Framework v4.6.1 our connections to a remote database immediately started timing out due to this change.

To fix simply add the parameter TransparentNetworkIPResolution in the connection string and set it to false:

Server=myServerName;Database=myDataBase;Trusted_Connection=True;TransparentNetworkIPResolution=False

This method would work for a list implementation and could be implemented as an extension method.

public void TestMethod()
{
    var first = new List<int> {1, 2, 3, 4, 5};
    var second = new List<string> {"One", "Two", "Three", "Four", "Five"};

    foreach(var value in this.Zip(first, second, (x, y) => new {Number = x, Text = y}))
    {
        Console.WriteLine("{0} - {1}",value.Number, value.Text);
    }
}

public IEnumerable<TResult> Zip<TFirst, TSecond, TResult>(List<TFirst> first, List<TSecond> second, Func<TFirst, TSecond, TResult> selector)
{
    if (first.Count != second.Count)
        throw new Exception();  

    for(var i = 0; i < first.Count; i++)
    {
        yield return selector.Invoke(first[i], second[i]);
    }
}

Basically, a Candidate Key is a Super Key from which no more Attribute can be pruned.

A Super Key identifies uniquely rows/tuples in a table/relation of a database. It is composed by a set of attributes that combined can assume values unique over the rows/tuples of a table/relation. A Candidate Key is built by a Super Key, iteratively removing/pruning non-key attributes, keeping an invariant: the newly created Key still need to uniquely identifies the rows/tuples.

A Candidate Key might be seen as a minimal Super Key, in terms of attributes.

Candidate Keys can be used to reference uniquely rows/tuples but from the RDBMS engine perspective the burden to maintain indexes on them is far heavier.

try instead:

if not os.path.exists(pathName):
    do this

To my knowledge, there isn't a built-in then() method in javascript (at the time of this writing).

It appears that whatever it is that doSome("task") is returning has a method called then.

If you log the return result of doSome() to the console, you should be able to see the properties of what was returned.

console.log( myObj.doSome("task") ); // Expand the returned object in the
                                     //   console to see its properties.

UPDATE (As of ECMAScript6) :-

The .then() function has been included to pure javascript.

From the Mozilla documentation here,

The then() method returns a Promise. It takes two arguments: callback functions for the success and failure cases of the Promise.

The Promise object, in turn, is defined as

The Promise object is used for deferred and asynchronous computations. A Promise represents an operation that hasn't completed yet, but is expected in the future.

That is, the Promise acts as a placeholder for a value that is not yet computed, but shall be resolved in the future. And the .then() function is used to associate the functions to be invoked on the Promise when it is resolved - either as a success or a failure.

You should use readfile():

readfile("/path/to/file");

This will read the file and send it to the browser in one command. This is essentially the same as:

echo file_get_contents("/path/to/file");

except that file_get_contents() may cause the script to crash for large files, while readfile() won't.

You can do this with JQueryUI:

$('a').mouseenter(function(){
  $(this).animate({
    color: '#ff0000'
  }, 1000);
}).mouseout(function(){
  $(this).animate({
    color: '#000000'
  }, 1000);
});

http://jsfiddle.net/dWCbk/

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

Using the csv module:

import csv

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    data = list(reader)

print(data)

Output:

[['This is the first line', 'Line1'], ['This is the second line', 'Line2'], ['This is the third line', 'Line3']]

If you need tuples:

import csv

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    data = [tuple(row) for row in reader]

print(data)

Output:

[('This is the first line', 'Line1'), ('This is the second line', 'Line2'), ('This is the third line', 'Line3')]

Old Python 2 answer, also using the csv module:

import csv
with open('file.csv', 'rb') as f:
    reader = csv.reader(f)
    your_list = list(reader)

print your_list
# [['This is the first line', 'Line1'],
#  ['This is the second line', 'Line2'],
#  ['This is the third line', 'Line3']]

just add them within the main bracket of the if statement like

if ((Type == 2 && PageCount == 0) || (Type == 2 && PageCount == '')) {
            PageCount= document.getElementById('<%=hfPageCount.ClientID %>').value;
}

Logically this can be rewritten in a better way too! This has exactly the same meaning

if (Type == 2 && (PageCount == 0 || PageCount == '')) {

http://rolandtapken.de/blog/2012-04/java-process-httpproxyuser-and-httpproxypassword says:

Other suggest to use a custom default Authenticator. But that's dangerous because this would send your password to anybody who asks.

This is relevant if some http/https requests don't go through the proxy (which is quite possible depending on configuration). In that case, you would send your credentials directly to some http server, not to your proxy.

He suggests the following fix.

// Java ignores http.proxyUser. Here come's the workaround.
Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        if (getRequestorType() == RequestorType.PROXY) {
            String prot = getRequestingProtocol().toLowerCase();
            String host = System.getProperty(prot + ".proxyHost", "");
            String port = System.getProperty(prot + ".proxyPort", "80");
            String user = System.getProperty(prot + ".proxyUser", "");
            String password = System.getProperty(prot + ".proxyPassword", "");

            if (getRequestingHost().equalsIgnoreCase(host)) {
                if (Integer.parseInt(port) == getRequestingPort()) {
                    // Seems to be OK.
                    return new PasswordAuthentication(user, password.toCharArray());  
                }
            }
        }
        return null;
    }  
});

I haven't tried it yet, but it looks good to me.

I modified the original version slightly to use equalsIgnoreCase() instead of equals(host.toLowerCase()) because of this: http://mattryall.net/blog/2009/02/the-infamous-turkish-locale-bug and I added "80" as the default value for port to avoid NumberFormatException in Integer.parseInt(port).

use "-e" to specify the sed-expression

cat input.txt | sed -e 's/foo/bar/g'

I was facing the same issue; and the following worked well for me. Hope this helps someone landing here:

<div class="row">
    <div class="col-md-6">
        <div class="col-md-12">
            Set room heater temperature
        </div>
    </div>
    <div class="col-md-6">
        <div class="col-md-12">
            Set room heater temperature
        </div>
    </div>
</div>

This will automatically render some space between the 2 divs.

If the iFrame content is not yours then the solution below will not work.

With Android all you need to do is to surround the iframe with a DIV and set the height on the div to document.documentElement.clientHeight. IOS, however, is a different animal. Although I have not yet tried Sharon's solution it does seem like a good solution. I did find a simpler solution but it only works with IOS 5.+.

Surround your iframe element with a DIV (lets call it scroller), set the height of the DIV and make sure that the new DIV has the following styling:

$('#scroller').css({'overflow' : 'auto', '-webkit-overflow-scrolling' : 'touch'});

This alone will work but you will notice that in most implementations the content in the iframe goes blank when scrolling and is basically rendered useless. My understanding is that this behavior has been reported as a bug to Apple as early as iOS 5.0. To get around that problem, find the body element in the iframe and add -webkit-transform', 'translate3d(0, 0, 0) like so:

$('#contentIframe').contents().find('body').css('-webkit-transform', 'translate3d(0, 0, 0)');

If your app or iframe is heavy on memory usage you might get a hitchy scroll for which you might need to use Sharon's solution.

in my webpack.config.js (Version 1,2,3) file, I have

function isExternal(module) {
  var context = module.context;

  if (typeof context !== 'string') {
    return false;
  }

  return context.indexOf('node_modules') !== -1;
}

in my plugins array

plugins: [
  new CommonsChunkPlugin({
    name: 'vendors',
    minChunks: function(module) {
      return isExternal(module);
    }
  }),
  // Other plugins
]

Now I have a file that only adds 3rd party libs to one file as required.

If you want get more granular where you separate your vendors and entry point files:

plugins: [
  new CommonsChunkPlugin({
    name: 'common',
    minChunks: function(module, count) {
      return !isExternal(module) && count >= 2; // adjustable
    }
  }),
  new CommonsChunkPlugin({
    name: 'vendors',
    chunks: ['common'],
    // or if you have an key value object for your entries
    // chunks: Object.keys(entry).concat('common')
    minChunks: function(module) {
      return isExternal(module);
    }
  })
]

Note that the order of the plugins matters a lot.

Also, this is going to change in version 4. When that's official, I update this answer.

Update: indexOf search change for windows users

Here is my understanding. Every time we set a seed value, a "label" or " reference" is generated. The next random.function call is attached to this "label", so next time you call the same seed value and random.function, it will give you the same result.

np.random.seed( 3 )
print(np.random.randn()) # output: 1.7886284734303186

np.random.seed( 3 )
print(np.random.rand()) # different function. output: 0.5507979025745755

np.random.seed( 5 )
print(np.random.rand()) # different seed value. output: 0.22199317108973948

I think you just need;

List<string> list = new List<string>();
list.Add("hai");

There is a difference between

List<string> list; 

and

List<string> list = new List<string>();

When you didn't use new keyword in this case, your list didn't initialized. And when you try to add it hai, obviously you get an error.

I was struggling with this issue for a while, primarily while running tests in my dev environment. I was able to resolve the issue with a simple setTimeout around a service call response!

This is what finally worked for me.

• Backend running on localhost:8080
• Fetch your IP address (ipconfig on Windows)

• Configure your Android emulator's proxy to use your IP address as host name and the port your backend is running on as port (in my case: 192.168.1.86:8080

• Have your Android app send requests to the same URL (192.168.1.86:8080) (sending requests to localhost, and http://10.0.2.2 did not work for me)

Include the jQuery file first:

Laravel supports aliases on tables and columns with AS. Try

$users = DB::table('really_long_table_name AS t')
           ->select('t.id AS uid')
           ->get();

Let's see it in action with an awesome tinker tool

$ php artisan tinker
[1] > Schema::create('really_long_table_name', function($table) {$table->increments('id');});
// NULL
[2] > DB::table('really_long_table_name')->insert(['id' => null]);
// true
[3] > DB::table('really_long_table_name AS t')->select('t.id AS uid')->get();
// array(
//   0 => object(stdClass)(
//     'uid' => '1'
//   )
// )

As of C# 6 you can declare and initialise a 'read-only auto-property' in one line:

double FuelConsumption { get; } = 2;

You can set the value from the constructor but not other methods.

get DLImageLoader and try folowing code

   [DLImageLoader loadImageFromURL:imageURL
                          completed:^(NSError *error, NSData *imgData) {
                              imageView.image = [UIImage imageWithData:imgData];
                              [imageView setContentMode:UIViewContentModeCenter];

                          }];

Another typical real-world example of using DLImageLoader, which may help someone...

PFObject *aFacebookUser = [self.fbFriends objectAtIndex:thisRow];
NSString *facebookImageURL = [NSString stringWithFormat:
    @"http://graph.facebook.com/%@/picture?type=large",
    [aFacebookUser objectForKey:@"id"] ];

__weak UIImageView *loadMe = self.userSmallAvatarImage;
// ~~note~~ you my, but usually DO NOT, want a weak ref
[DLImageLoader loadImageFromURL:facebookImageURL
   completed:^(NSError *error, NSData *imgData)
    {
    if ( loadMe == nil ) return;

    if (error == nil)
        {
        UIImage *image = [UIImage imageWithData:imgData];
        image = [image ourImageScaler];
        loadMe.image = image;
        }
    else
        {
        // an error when loading the image from the net
        }
    }];

As I mention above another great library to consider these days is Haneke (unfortunately it's not as lightweight).

• Iterative - you don't finish a feature in one go. You are in a code >> get feedback >> code >> ... cycle. You keep iterating till done.
• Incremental - you build as much as you need right now. You don't over-engineer or add flexibility unless the need is proven. When the need arises, you build on top of whatever already exists. (Note: differs from iterative in that you're adding new things.. vs refining something).
• Agile - you are agile if you value the same things as listed in the agile manifesto. It also means that there is no standard template or checklist or procedure to "do agile". It doesn't overspecify.. it just states that you can use whatever practices you need to "be agile". Scrum, XP, Kanban are some of the more prescriptive 'agile' methodologies because they share the same set of values. Continuous and early feedback, frequent releases/demos, evolve design, etc.. hence they can be iterative and incremental.

abline(h=mean(x))

for a horizontal line (use v instead of h for vertical if you orient your boxplot horizontally), or

points(mean(x))

for a point. Use the parameter pch to change the symbol. You may want to colour them to improve visibility too.

Note that these are called after you have drawn the boxplot.

If you are using the formula interface, you would have to construct the vector of means. For example, taking the first example from ?boxplot:

boxplot(count ~ spray, data = InsectSprays, col = "lightgray")
means <- tapply(InsectSprays$count,InsectSprays$spray,mean)
points(means,col="red",pch=18)

If your data contains missing values, you might want to replace the last argument of the tapply function with function(x) mean(x,na.rm=T)

Most probably, AllowOverride is set to None. in Directory section of apache2.conf located in /etc/apache2 folder

Try setting it to AllowOverride All

The only (& even though cumbersome but yet expedient / relatively quick) way I can do this, is to concatenate the any-dimensional array, and reduce it to 1 dimension, with "/[column number]//\|" as the delimiter.

& use a single-cell result multiple lookupall macro function on the this 1-d column.

& then index match to pull out the positions. (usuing multiple find match)

That way you get all matching occurrences of the element/string your looking for, in the original any-dimension array, and their positions. In one cell.

Wish I could write a macro / function for this entire process. It would save me more fuss.

Your error is caused by these:

Dim oTable As Table, oRow As Row,

These types, Table and Row are not variable types native to Excel. You can resolve this in one of two ways:

1. Include a reference to the Microsoft Word object model. Do this from Tools | References, then add reference to MS Word. While not strictly necessary, you may like to fully qualify the objects like Dim oTable as Word.Table, oRow as Word.Row. This is called early-binding.
2. Alternatively, to use late-binding method, you must declare the objects as generic Object type: Dim oTable as Object, oRow as Object. With this method, you do not need to add the reference to Word, but you also lose the intellisense assistance in the VBE.

I have not tested your code but I suspect ActiveDocument won't work in Excel with method #2, unless you properly scope it to an instance of a Word.Application object. I don't see that anywhere in the code you have provided. An example would be like:

Sub DeleteEmptyRows()
Dim wdApp as Object
Dim oTable As Object, As Object, _
TextInRow As Boolean, i As Long

Set wdApp = GetObject(,"Word.Application")

Application.ScreenUpdating = False

For Each oTable In wdApp.ActiveDocument.Tables

Slightly shorter version using methods chain:

var list = new List<string> {"a", "b", "a", "c", "a", "b"};
var q = list.GroupBy(x => x)
            .Select(g => new {Value = g.Key, Count = g.Count()})
            .OrderByDescending(x=>x.Count);

foreach (var x in q)
{
    Console.WriteLine("Value: " + x.Value + " Count: " + x.Count);
}

Wen-wei Liao's answer is good if you are not trying to export vector graphics or that you have set up your matplotlib backends to ignore colorless axes; otherwise the hidden axes would show up in the exported graphic.

My answer suplabel here is similar to the fig.suptitle which uses the fig.text function. Therefore there is no axes artist being created and made colorless. However, if you try to call it multiple times you will get text added on top of each other (as fig.suptitle does too). Wen-wei Liao's answer doesn't, because fig.add_subplot(111) will return the same Axes object if it is already created.

My function can also be called after the plots have been created.

def suplabel(axis,label,label_prop=None,
             labelpad=5,
             ha='center',va='center'):
    ''' Add super ylabel or xlabel to the figure
    Similar to matplotlib.suptitle
    axis       - string: "x" or "y"
    label      - string
    label_prop - keyword dictionary for Text
    labelpad   - padding from the axis (default: 5)
    ha         - horizontal alignment (default: "center")
    va         - vertical alignment (default: "center")
    '''
    fig = pylab.gcf()
    xmin = []
    ymin = []
    for ax in fig.axes:
        xmin.append(ax.get_position().xmin)
        ymin.append(ax.get_position().ymin)
    xmin,ymin = min(xmin),min(ymin)
    dpi = fig.dpi
    if axis.lower() == "y":
        rotation=90.
        x = xmin-float(labelpad)/dpi
        y = 0.5
    elif axis.lower() == 'x':
        rotation = 0.
        x = 0.5
        y = ymin - float(labelpad)/dpi
    else:
        raise Exception("Unexpected axis: x or y")
    if label_prop is None: 
        label_prop = dict()
    pylab.text(x,y,label,rotation=rotation,
               transform=fig.transFigure,
               ha=ha,va=va,
               **label_prop)

You need to do this:

OleDbConnection connection = new OleDbConnection(
    "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet DS = new DataSet();
connection.Open();

string query = 
    @"SELECT tbl_Computer.*,  tbl_Besitzer.*
    FROM tbl_Computer 
    INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID 
    WHERE (((tbl_Besitzer.Vorname)='ma'))";
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand(query, connection); 
DBAdapter.Fill(DS);

By the way, what is this DataSet1? This should be "DataSet".

For those using React, detecting a same-origin iframe load event is as simple as setting onLoad event listener on iframe element.

<iframe src={'path-to-iframe-source'} onLoad={this.loadListener} frameBorder={0} />

I've experienced the same issue because of certifi library. Installing a different version helped me as well.

As Peter says, they won't be in Maven Central

from the Android SDK Manager download the 'Android Support Repository' and a Maven repo of the support libraries will be downloaded to your Android SDK directory (see 'extras' folder)

to deploy the libraries to your local .m2 repository you can use maven-android-sdk-deployer

2017 edit:

you can now reference the Google online M2 repo

repositories {
google()
jcenter()
}

The Eclipse team with The Open University have prepared the following document, which includes creating proxy classes with tests. It might be what you are looking for.

http://www.eclipse.org/webtools/community/education/web/t320/Generating_a_client_from_WSDL.pdf

Everything is included in the Dynamic Web Project template.

In the project create a Web Service Client. This starts a wizard that has you point out a wsdl url and creates the client with tests for you.

The user guide (targeted at indigo though) for this task is found at http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.jst.ws.cxf.doc.user%2Ftasks%2Fcreate_client.html.

To set https globally instead of git://:

git config --global url.https://github.com/.insteadOf git://github.com/

It will work in IE7. But here you need to fixed the size less than the number of option and not use overflow-y:scroll. In your example you have 2 option but you set size=10, which will not work.

Suppose your select has 10 option, then fixed size=9.

Here, in your code reference you used height:100px with size:2. I remove the height css, because its not necessary and change the size:5 and it works fine.

Here is your modified code from jsfiddle:

<select size="5" style="width:100px;">
 <option>1</option>
 <option>2</option>
 <option>3</option>
 <option>4</option>
 <option>5</option>
 <option>6</option>
</select>

this will generate a larger select box than size:2 create.In case of small size the select box will not display the scrollbar,you have to check with appropriate size quantity.Without scrollbar it will work if click on the upper and lower icons of scrollbar.I show both example in your fiddle with size:2 and size greater than 2(e.g: 3,5).

Here is your desired result. I think this will help you:

CSS

  .wrapper{
    border: 1px dashed red;
    height: 150px;
    overflow-x: hidden;
    overflow-y: scroll;
    width: 150px;
 }
 .wrapper .selection{
   width:150px;
   border:1px solid #ccc
 }

HTML

<div class="wrapper">
<select size="15" class="selection">
    <option>Item 1</option>
    <option>Item 2</option>
    <option>Item 3</option>
</select>
</div>

The setInterval() method, repeatedly calls a function or executes a code snippet, with a fixed time delay between each call. It returns an interval ID which uniquely identifies the interval, so you can remove it later by calling clearInterval().

var intervalId = setInterval(function() {
  alert("Interval reached every 5s")
}, 5000);

// You can clear a periodic function by uncommenting:
// clearInterval(intervalId);

See more @ setInterval() @ MDN Web Docs

I'm not sure why the accepted answer was accepted if the suggested solution did not and does not solve the issue. There can actually be two related issues related to this topic.

Issue #1

The master page (e.g. _Layout.cshtml) has a section defined and it is required but the inheriting views did not implement it. For example,

The Layout Template

<body>
    @* Visible only to admin users *@
    <div id="option_box"> 
        @* this section is required due to the absence of the second parameter *@
        @RenderSection("OptionBox") 
    </div>
</body>

The Inheriting View

No need to show any code, just consider that there is no implementation of @section OptionBox {} on the view.

The Error for Issue #1

Section not defined: "OptionBox ".

Issue #2

The master page (e.g. _Layout.cshtml) has a section defined and it is required AND the inheriting view did implement it. However, the implementing view have additional script sections that are not defined on (any of) its master page(s).

The Layout Template

same as above

The Inheriting View

<div>
  <p>Looks like the Lakers can still make it to the playoffs</p>
</div>
@section OptionBox {
<a href"">Go and reserve playoff tickets now</a>
}
@section StatsBox {
<ul>
    <li>1. San Antonio</li>
    <li>8. L. A. Lakers</li>
</ul>
}

The Error for Issue #2

The following sections have been defined but have not been rendered for the layout page "~/Views/Shared/_Layout.cshtml": "StatsBox"

The OP's issue is similar to Issue #2 and the accepted answer is for Issue #1.

 // Get calendar set to the current date and time
Calendar cal = Calendar.getInstance();

// Set time of calendar to 18:00
cal.set(Calendar.HOUR_OF_DAY, 18);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);

// Check if current time is after 18:00 today
boolean afterSix = Calendar.getInstance().after(cal);

if (afterSix) {
    System.out.println("Go home, it's after 6 PM!");
}
else {
    System.out.println("Hello!");
}

I'm working with CocoaPods frameworks and in case UIApplication.shared is unavailable then I use safeAreaInsets in view's window:

if #available(iOS 11.0, *) {
    let insets = view.window?.safeAreaInsets
    let top = insets.top
    let bottom = insets.bottom
}

Use the > command. To indent five lines, 5>>. To mark a block of lines and indent it, Vjj> to indent three lines (Vim only). To indent a curly-braces block, put your cursor on one of the curly braces and use >% or from anywhere inside block use >iB.

If you’re copying blocks of text around and need to align the indent of a block in its new location, use ]p instead of just p. This aligns the pasted block with the surrounding text.

Also, the shiftwidth setting allows you to control how many spaces to indent.

install these two packages

npm i --save-dev react-app-rewired customize-cra

package.json

"scripts": {
    - "start": "react-scripts start"
    + "start": "react-app-rewired start"
},

config-overrides.js

const { removeModuleScopePlugin } = require('customize-cra');

module.exports = function override(config, env) {
    if (!config.plugins) {
        config.plugins = [];
    }
    removeModuleScopePlugin()(config);

    return config;
};

The heredoc syntax is much cleaner to me and it is really useful for multi-line strings and avoiding quoting issues. Back in the day I used to use them to construct SQL queries:

$sql = <<<SQL
select *
  from $tablename
 where id in [$order_ids_list]
   and product_name = "widgets"
SQL;

To me this has a lower probability of introducing a syntax error than using quotes:

$sql = "
select *
  from $tablename
 where id in [$order_ids_list]
   and product_name = \"widgets\"
";

Another point is to avoid escaping double quotes in your string:

$x = "The point of the \"argument" was to illustrate the use of here documents";

The problem with the above is the syntax error (the missing escaped quote) I just introduced as opposed to here document syntax:

$x = <<<EOF
The point of the "argument" was to illustrate the use of here documents
EOF;

It is a bit of style, but I use the following as rules for single, double and here documents for defining strings:

• Single quotes are used when the string is a constant like 'no variables here'
• Double quotes when I can put the string on a single line and require variable interpolation or an embedded single quote "Today is ${user}'s birthday"
• Here documents for multi-line strings that require formatting and variable interpolation.

You can be specific by testing for not valid characters. This will return true for anything not alphanumeric and space:

var specials = /[^A-Za-z 0-9]/g;
return specials.test(input.val());

First you should ask yourself the following question: Do you really need an int?

The purpose of enums is to have a collection of items (constants), that have a meaning in the code without relying on an external value (like an int). Enums in Java can be used as an argument on switch statments and they can safely be compared using "==" equality operator (among others).

Proposal 1 (no int needed) :

Often there is no need for an integer behind it, then simply use this:

private enum DownloadType{
    AUDIO, VIDEO, AUDIO_AND_VIDEO
}

Usage:

DownloadType downloadType = MyObj.getDownloadType();
if (downloadType == DownloadType.AUDIO) {
    //...
}
//or
switch (downloadType) {
  case AUDIO:  //...
          break;
  case VIDEO: //...
          break;
  case AUDIO_AND_VIDEO: //...
          break;
}

Proposal 2 (int needed) :

Nevertheless, sometimes it may be useful to convert an enum to an int (for instance if an external API expects int values). In this case I would advise to mark the methods as conversion methods using the toXxx()-Style. For printing override toString().

private enum DownloadType {
    AUDIO(2), VIDEO(5), AUDIO_AND_VIDEO(11);
    private final int code;

    private DownloadType(int code) {
        this.code = code;
    }

    public int toInt() {
        return code;
    }

    public String toString() {
        //only override toString, if the returned value has a meaning for the
        //human viewing this value 
        return String.valueOf(code);
    }
}

System.out.println(DownloadType.AUDIO.toInt());           //returns 2
System.out.println(DownloadType.AUDIO);                   //returns 2 via `toString/code`
System.out.println(DownloadType.AUDIO.ordinal());         //returns 0
System.out.println(DownloadType.AUDIO.name());            //returns AUDIO
System.out.println(DownloadType.VIDEO.toInt());           //returns 5
System.out.println(DownloadType.VIDEO.ordinal());         //returns 1
System.out.println(DownloadType.AUDIO_AND_VIDEO.toInt()); //returns 11

Summary

• Don't use an Integer together with an enum if you don't have to.
• Don't rely on using ordinal() for getting an integer of an enum, because this value may change, if you change the order (for example by inserting a value). If you are considering to use ordinal() it might be better to use proposal 1.
• Normally don't use int constants instead of enums (like in the accepted answer), because you will loose type-safety.

You should use datetime object, not str.

>>> from datetime import datetime
>>> cr_date = datetime(2013, 10, 31, 18, 23, 29, 227)
>>> cr_date.strftime('%m/%d/%Y')
'10/31/2013'

To get the datetime object from the string, use datetime.datetime.strptime:

>>> datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
datetime.datetime(2013, 10, 31, 18, 23, 29, 227)
>>> datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f').strftime('%m/%d/%Y')
'10/31/2013'
