While searching for a way to round tabs, I found Carlo's answer and it did help but I needed a bit more. Here is what I put together, based on his work. This was done with MS Visual Studio 2015.

The Code:

Screenshot:

I would pick a table size of n * 1.5 or n + (n >> 1), this would give a load factor of .66666~ without division, which is slow on most systems, especially on portable systems where there is no division in the hardware.

I resolved error copying the files class.phpmailer.php , class.smtp.php to the folder where the file is PHPMailerAutoload.php, of course there should be the file that we will use to send the email.

Are you looking for

\begin{cases}
  math text
\end{cases}

It wasn't very clear from the description. But may be this is what you are looking for http://en.wikipedia.org/wiki/Help:Displaying_a_formula#Continuation_and_cases

In your js/ts file for the html that will be hovered

@Output() elemHovered: EventEmitter<any> = new EventEmitter<any>();
onHoverEnter(): void {
    this.elemHovered.emit([`The button was entered!`,this.event]);
}

onHoverLeave(): void {
    this.elemHovered.emit([`The button was left!`,this.event])
}

In your HTML that will be hovered

 (mouseenter) = "onHoverEnter()" (mouseleave)="onHoverLeave()"

In your js/ts file that will receive info of the hovering

elemHoveredCatch(d): void {
    console.log(d)
}

In your HTML element that is connected with catching js/ts file

(elemHovered) = "elemHoveredCatch($event)"

If you try calling equals on a null object reference, then you'll get a null pointer exception thrown.

This is the best way for me:

cat filename.tsv  |
    while read FILENAME
    do
    sudo find /PATH_FROM/  -name "$FILENAME" -maxdepth 4 -exec cp '{}' /PATH_TO/ \; ;
    done

alias_method can be redefined if need be. (it's defined in the Module class.)

alias's behavior changes depending on its scope and can be quite unpredictable at times.

Verdict: Use alias_method - it gives you a ton more flexibility.

Usage:

def foo
  "foo"
end

alias_method :baz, :foo

I went with using the regex from detectmobilebrowser.com to check against the user-agent string. Even tho it says it was last updated in 2014 it was accurate on the devices I tested.

Here is the C# code I got from them at the time of submitting this answer:

Best way to do is :

[self performSelector:@selector(YourFunctionName) 
           withObject:(can be Self or Object from other Classes) 
           afterDelay:(Time Of Delay)];

you can also pass nil as withObject parameter.

example :

[self performSelector:@selector(subscribe) withObject:self afterDelay:3.0 ];

Previous answer didn't work for me.

But this worked perfectly. Convert Data URI to File then append to FormData

May i add to Stormenet example some KISS (Keep It Simple & Stupid):

If you already have a treeView or just created an instance of it: Let's populate with some data - Ex. One parent two child's :

            treeView1.Nodes.Add("ParentKey","Parent Text");
            treeView1.Nodes["ParentKey"].Nodes.Add("Child-1 Text");
            treeView1.Nodes["ParentKey"].Nodes.Add("Child-2 Text");

Another Ex. two parent's first have two child's second one child:

            treeView1.Nodes.Add("ParentKey1","Parent-1  Text");
            treeView1.Nodes.Add("ParentKey2","Parent-2 Text");
            treeView1.Nodes["ParentKey1"].Nodes.Add("Child-1 Text");
            treeView1.Nodes["ParentKey1"].Nodes.Add("Child-2 Text");
            treeView1.Nodes["ParentKey2"].Nodes.Add("Child-3 Text");

Take if farther - sub child of child 2:

            treeView1.Nodes.Add("ParentKey1","Parent-1  Text");
            treeView1.Nodes["ParentKey1"].Nodes.Add("Child-1 Text");
            treeView1.Nodes["ParentKey1"].Nodes.Add("ChildKey2","Child-2 Text");
            treeView1.Nodes["ParentKey1"].Nodes["ChildKey2"].Nodes.Add("Child-3 Text");

As you see you can have as many child's and parent's as you want and those can have sub child's of child's and so on.... Hope i help!

The use of @Qualifier will solve the issue.
Explained as below example : 
public interface PersonType {} // MasterInterface

@Component(value="1.2") 
public class Person implements  PersonType { //Bean implementing the interface
@Qualifier("1.2")
    public void setPerson(PersonType person) {
        this.person = person;
    }
}

@Component(value="1.5")
public class NewPerson implements  PersonType { 
@Qualifier("1.5")
    public void setNewPerson(PersonType newPerson) {
        this.newPerson = newPerson;
    }
}

Now get the application context object in any component class :

Object obj= BeanFactoryAnnotationUtils.qualifiedBeanOfType((ctx).getAutowireCapableBeanFactory(), PersonType.class, type);//type is the qualifier id

you can the object of class of which qualifier id is passed.

Go to package manager console(in visual studio) and execute below command

C:\Users\<YOUR_USER>\.nuget\packages\Microsoft.EntityFrameworkCore.Tools\<YOUR_INSTALLED_VERSION>\tools\init.ps1

I haven't fully explored the TPL but they might have something that fits your needs, or at the very least, some Reflector fodder to snag some inspiration from.

Hope that helps.

"WORKSPACE" environment variable works for the latest version of Jenkins Pipeline. You can use this in your Jenkins file: "${env.WORKSPACE}"

Sample use below:

def files = findFiles glob: '**/reports/*.json'
for (def i=0; i<files.length; i++) {
jsonFilePath = "${files[i].path}"       
jsonPath = "${env.WORKSPACE}" + "/" + jsonFilePath
echo jsonPath

hope that helps!!

I am surprised why there is not a CrytpoGraphic solution in place. GUID is unique but not cryptographically safe. See this Dotnet Fiddle.

var bytes = new byte[40]; // byte size
using (var crypto = new RNGCryptoServiceProvider())
  crypto.GetBytes(bytes);

var base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

In case you want to Prepend with a Guid:

var result = Guid.NewGuid().ToString("N") + base64;
Console.WriteLine(result);

A cleaner alphanumeric string:

result = Regex.Replace(result,"[^A-Za-z0-9]","");
Console.WriteLine(result);

I found this FAQ from the US Bureau of Industry and Security very helpful.

Question 15 (What is Note 4?) is the important point:

...

Examples of items that are excluded from Category 5, Part 2 by Note 4 include, but are not limited to, the following:

Consumer applications. Some examples:

piracy and theft prevention for software or music; music, movies, tunes/music, digital photos – players, recorders and organizers games/gaming – devices, runtime software, HDMI and other component interfaces, development tools LCD TV, Blu-ray / DVD, video on demand (VoD), cinema, digital video recorders (DVRs) / personal video recorders (PVRs) – devices, on-line media guides, commercial content integrity and protection, HDMI and other component interfaces (not videoconferencing); printers, copiers, scanners, digital cameras, Internet cameras – including parts and sub-assemblies household utilities and appliances

I've not tried it myself, but Visual Studio 2005 (and later) support the concept of Debugger Visualizers. This allows you to customize how an object is shown in the IDE. Check out this article for more details.

WebSockets:

• Ratified IETF standard (6455) with support across all modern browsers and even legacy browsers using web-socket-js polyfill.

• Uses HTTP compatible handshake and default ports making it much easier to use with existing firewall, proxy and web server infrastructure.

• Much simpler browser API. Basically one constructor with a couple of callbacks.

• Client/browser to server only.

• Only supports reliable, in-order transport because it is built On TCP. This means packet drops can delay all subsequent packets.

WebRTC:

• Just beginning to be supported by Chrome and Firefox. MS has proposed an incompatible variant. The DataChannel component is not yet compatible between Firefox and Chrome.

• WebRTC is browser to browser in ideal circumstances but even then almost always requires a signaling server to setup the connections. The most common signaling server solutions right now use WebSockets.

• Transport layer is configurable with application able to choose if connection is in-order and/or reliable.

• Complex and multilayered browser API. There are JS libs to provide a simpler API but these are young and rapidly changing (just like WebRTC itself).

To exit a script you can use,

import sys
sys.exit()

You can also provide an exit status value, usually an integer.

import sys
sys.exit(0)

Exits with zero, which is generally interpreted as success. Non-zero codes are usually treated as errors. The default is to exit with zero.

import sys
sys.exit("aa! errors!")

Prints "aa! errors!" and exits with a status code of 1.

There is also an _exit() function in the os module. The sys.exit() function raises a SystemExit exception to exit the program, so try statements and cleanup code can execute. The os._exit() version doesn't do this. It just ends the program without doing any cleanup or flushing output buffers, so it shouldn't normally be used.

The Python docs indicate that os._exit() is the normal way to end a child process created with a call to os.fork(), so it does have a use in certain circumstances.

For a Ruby on Rails application, I was able to prevent a layout from loading by specifying render layout: false in the controller action that I wanted to respond with ajax html.

Class methods provide a "semantic sugar" (don't know if this term is widely used) - or "semantic convenience".

Example: you got a set of classes representing objects. You might want to have the class method all() or find() to write User.all() or User.find(firstname='Guido'). That could be done using module level functions of course...

The Math.round function is overloaded When it receives a float value, it will give you an int. For example this would work.

int a=Math.round(1.7f);

When it receives a double value, it will give you a long, therefore you have to typecast it to int.

int a=(int)Math.round(1.7);

This is done to prevent loss of precision. Your double value is 64bit, but then your int variable can only store 32bit so it just converts it to long, which is 64bit but you can typecast it to 32bit as explained above.

I'm assuming that when you type int file.msi into the command line, Windows is automatically calling msiexec file.msi for you. I'm assuming this because when you type in picture.png it brings up the default picture viewer.

To fix this go to TortoiseSVN > settings > Icon Overlays > Status cache changed from default to shell.

If the drive A or B is used check the Drive type as A and B.

I had a similar error but not from a Conversion...

System.Web.HttpException: 'Namespace.Website.MasterUserPages' is not allowed here because it does not extend class 'System.Web.UI.MasterPage'

I was also extending the MasterPage class.

The error was due to a simple compilation error in my Master Page itself:

System.Web.HttpCompileException: c:\directory\path\Website\MasterUserPages.Master(30): error CS1061: 'ASP.masteruserpages_master' does not contain a definition for 'btnHelp_Click' and no extension method 'btnHelp_Click' accepting a first argument of type 'ASP.masteruserpages_master' could be found (are you missing a using directive or an assembly reference?)

I was not able to see the error until I moved the MasterPage to the root website folder. Once that was taken care of I was able to put my MasterPage back in the folder I wanted.

You can send Email by Jquery just follow these steps 

include this link : <script src="https://smtpjs.com/v3/smtp.js"></script>
after that use this code :

$( document ).ready(function() {
 Email.send({
Host : "smtp.yourisp.com",
Username : "username",
Password : "password",
To : '[email protected]',
From : "[email protected]",
Subject : "This is the subject",
Body : "And this is the body"}).then( message => alert(message));});

A new jQuery plugin for cookie retrieval and manipulation with binding for forms, etc: http://plugins.jquery.com/project/cookies

var request = require('request');
 function updateClient(postData){
            var clientServerOptions = {
                uri: 'http://'+clientHost+''+clientContext,
                body: JSON.stringify(postData),
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json'
                }
            }
            request(clientServerOptions, function (error, response) {
                console.log(error,response.body);
                return;
            });
        }

For this to work, your server must be something like:

var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json())

var port = 9000;

app.post('/sample/put/data', function(req, res) {
    console.log('receiving data ...');
    console.log('body is ',req.body);
    res.send(req.body);
});

// start the server
app.listen(port);
console.log('Server started! At http://localhost:' + port);

Try WebClient.DownloadFileAsync(). You can call CancelAsync() by timer with your own timeout.

To add on to what Egon said, simply create your blob called "folder/1.txt", and it will work. No need to create a directory.

For others needing a key binding:

{ "keys": ["ctrl+="], "command": "upper_case" },
{ "keys": ["ctrl+-"], "command": "lower_case" }

This works:

<select name="foo" id="foo">
<option value="1">a</option>
<option value="2">b</option>
<option value="3">c</option>
</select>
<input type="button" id="button" value="Button" />

$('#button').click(function() {
    alert($('#foo option:selected').text());
    alert($('#foo option:selected').val());
});

mentioned also here, you can use this:

import collections
Point = collections.namedtuple('Point', ['x', 'y'])
p = Point(1, y=2)
>>> p.x, p.y
1 2
>>> p[0], p[1]
1 2

Why has nobody used sprintf?

#include <string>
#include <stdio.h>

static const std::string str = "hello world!";

int main()
{
  //copy the data from the string to a char array
  char *strarr = new char[str.size()+1];
  strarr[str.size()+1] = 0; //set the null terminator
  memcpy(strarr, str.c_str(),str.size()); //memory copy to the char array

  printf(strarr);
  printf("\n\nHEX: ");

  //now print the data
  for(int i = 0; i < str.size()+1; i++)
  {
    char x = strarr[i];
    sprintf("%x ", reinterpret_cast<const char*>(x));
  }

  //DO NOT FORGET TO DELETE
  delete(strarr);

  return 0;
}

There is a new extension for Visual Studio 2017 called SelectNextOccurrence which is free and open-source.

This extension makes it possible to select next occurrences of a selected text for editing.

Aims to replicate the Ctrl+D command of Sublime Text for faster coding.

Features:

• Select next occurrence of current selection.
• Skip occurrence
• Undo occurrence
• Add caret above/below
• Use multiple carets to edit (Alt-click to add caret)

Visual Studio commands:

• SelectNextOccurrence.SelectNextOccurrence is bound to Ctrl+D by default.
• SelectNextOccurrence.SkipOccurrence is not bound by default. (Recommended Ctrl+K, Ctrl+D)
• SelectNextOccurrence.UndoOccurrence is not bound by default. (Recommended Ctrl+U)
• SelectNextOccurrence.AddCaretAbove is not bound by default. (Recommended Ctrl+Alt+Up)
• SelectNextOccurrence.AddCaretBelow is not bound by default. (Recommended Ctrl+Alt+Down)

@JigarJoshi it's the good answer, and of course also @Tim recommendation to use .joda-time.

I only want to add more possibilities to subtract days from a java.util.Date.

Apache-commons

One possibility is to use apache-commons-lang. You can do it using DateUtils as follows:

Date dateBefore30Days = DateUtils.addDays(new Date(),-30);

Of course add the commons-lang dependency to do only date subtract it's probably not a good options, however if you're already using commons-lang it's a good choice. There is also convenient methods to addYears,addMonths,addWeeks and so on, take a look at the api here.

Java 8

Another possibility is to take advantage of new LocalDate from Java 8 using minusDays(long days) method:

LocalDate dateBefore30Days = LocalDate.now(ZoneId.of("Europe/Paris")).minusDays(30);

You can use an index in a range and then access the array via its index:

<ul>
  <li v-for="index in 10" :key="index">
    {{ shoppingItems[index].name }} - {{ shoppingItems[index].price }}
  </li>
</ul>

You can also check the Official Documentation for more information.

or if you don't want anything fancy like animation etc. you can create a label and dock it to form then change it's z-index from document outline window to 0 and give it a background color so other controls wont be visible than run Application.DoEvents() once in form load event and do all your coding in form shown event and at the and of shown event set your label visible property to false then run Application.DoEvents() again.

If you've got an image in the Icons folder of your project and its build action is "Resource", you can refer to it like this:

<Image Source="/Icons/play_small.png" />

That's the simplest way to do it. This is the only way I could figure doing it purely from the resource standpoint and no project files:

var resourceManager = new ResourceManager(typeof (Resources));
var bitmap = resourceManager.GetObject("Search") as System.Drawing.Bitmap;

var memoryStream = new MemoryStream();
bitmap.Save(memoryStream, System.Drawing.Imaging.ImageFormat.Bmp);
memoryStream.Position = 0;

var bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.StreamSource = memoryStream;
bitmapImage.EndInit();

this.image1.Source = bitmapImage;

@Adam Augusta is right, One more thing

Apache-HTTP client jars also comes in same category as some google-apis.

org.apache.httpcomponents.httpclient_4.2.jar and commons-codec-1.4.jar both on classpath, This is very possible that you will get this problem.

This prove to all jars which are using early version of common-codec internally and at the same time someone using common-codec explicitly on classpath too.

IF YOU CAN AVOID IT.. DON'T DO IT

Databases aren't really designed for this, you are effectively trying to create data (albeit a list of dates) within a query.

For anyone who has an application layer above the DB query the simplest solution is to fill in the blank data there.

You'll more than likely be looping through the query results anyway and can implement something like this:

loop_date = start_date

while (loop_date <= end_date){

  if(loop_date in db_data) {
    output db_data for loop_date
  }
  else {
    output default_data for loop_date
  }

  loop_date = loop_date + 1 day
}

The benefits of this are reduced data transmission; simpler, easier to debug queries; and no worry of over-flowing the calendar table.

As @S.Lott says, you should be opening your files in 'rb' mode, not 'rU' mode. However that may NOT be causing your current problem. As far as I know, using 'rU' mode would mess you up if there are embedded \r in the data, but not cause any other dramas. I also note that you have several files (all opened with 'rU' ??) but only one causing a problem.

If the csv module says that you have a "NULL" (silly message, should be "NUL") byte in your file, then you need to check out what is in your file. I would suggest that you do this even if using 'rb' makes the problem go away.

repr() is (or wants to be) your debugging friend. It will show unambiguously what you've got, in a platform independant fashion (which is helpful to helpers who are unaware what od is or does). Do this:

print repr(open('my.csv', 'rb').read(200)) # dump 1st 200 bytes of file

and carefully copy/paste (don't retype) the result into an edit of your question (not into a comment).

Also note that if the file is really dodgy e.g. no \r or \n within reasonable distance from the start of the file, the line number reported by reader.line_num will be (unhelpfully) 1. Find where the first \x00 is (if any) by doing

data = open('my.csv', 'rb').read()
print data.find('\x00')

and make sure that you dump at least that many bytes with repr or od.

What does data.count('\x00') tell you? If there are many, you may want to do something like

for i, c in enumerate(data):
    if c == '\x00':
        print i, repr(data[i-30:i]) + ' *NUL* ' + repr(data[i+1:i+31])

so that you can see the NUL bytes in context.

If you can see \x00 in the output (or \0 in your od -c output), then you definitely have NUL byte(s) in the file, and you will need to do something like this:

fi = open('my.csv', 'rb')
data = fi.read()
fi.close()
fo = open('mynew.csv', 'wb')
fo.write(data.replace('\x00', ''))
fo.close()

By the way, have you looked at the file (including the last few lines) with a text editor? Does it actually look like a reasonable CSV file like the other (no "NULL byte" exception) files?

First you need to declare the window object in current scope.
Because typescript would like to know the type of the object.
Since window object is defined somewhere else you can not redefine it.
But you can declare it as follows:-

declare var window: any;

This will not redefine the window object or it will not create another variable with name window.
This means window is defined somewhere else and you are just referencing it in current scope.

Then you can refer to your MyNamespace object simply by:-

window.MyNamespace

Or you can set the new property on window object simply by:-

window.MyNamespace = MyObject

And now the typescript won't complain.

TL;DR No, it can't be done automatically. Yes, it is possible.

import matplotlib.pyplot as plt
my_colors = plt.rcParams['axes.prop_cycle']() # <<< note that we CALL the prop_cycle
fig, axes = plt.subplots(2,3)
for ax in axes.flatten(): ax.plot((0,1), (0,1), **next(my_colors))

Each plot (axes) in a figure (figure) has its own cycle of colors — if you don't force a different color for each plot, all the plots share the same order of colors but, if we stretch a bit what "automatically" means, it can be done.

The OP wrote

[...] I have to identify each plot with a different color which should be automatically generated by [Matplotlib].

But... Matplotlib automatically generates different colors for each different curve

In [10]: import numpy as np
    ...: import matplotlib.pyplot as plt

In [11]: plt.plot((0,1), (0,1), (1,2), (1,0));
Out[11]:

So why the OP request? If we continue to read, we have

Can you please give me a method to put different colors for different plots in the same figure?

and it make sense, because each plot (each axes in Matplotlib's parlance) has its own color_cycle (or rather, in 2018, its prop_cycle) and each plot (axes) reuses the same colors in the same order.

In [12]: fig, axes = plt.subplots(2,3)

In [13]: for ax in axes.flatten():
    ...:     ax.plot((0,1), (0,1))

If this is the meaning of the original question, one possibility is to explicitly name a different color for each plot.

If the plots (as it often happens) are generated in a loop we must have an additional loop variable to override the color automatically chosen by Matplotlib.

In [14]: fig, axes = plt.subplots(2,3)

In [15]: for ax, short_color_name in zip(axes.flatten(), 'brgkyc'):
    ...:     ax.plot((0,1), (0,1), short_color_name)

Another possibility is to instantiate a cycler object

from cycler import cycler
my_cycler = cycler('color', ['k', 'r']) * cycler('linewidth', [1., 1.5, 2.])
actual_cycler = my_cycler()

fig, axes = plt.subplots(2,3)
for ax in axes.flat:
    ax.plot((0,1), (0,1), **next(actual_cycler))

Note that type(my_cycler) is cycler.Cycler but type(actual_cycler) is itertools.cycle.

Using the accepted answer my script kept returning exceptionally early (right after 'exec > >(tee ...)') leaving the rest of my script running in the background. As I couldn't get that solution to work my way I found another solution/work around to the problem:

# Logging setup
logfile=mylogfile
mkfifo ${logfile}.pipe
tee < ${logfile}.pipe $logfile &
exec &> ${logfile}.pipe
rm ${logfile}.pipe

# Rest of my script

This makes output from script go from the process, through the pipe into the sub background process of 'tee' that logs everything to disc and to original stdout of the script.

Note that 'exec &>' redirects both stdout and stderr, we could redirect them separately if we like, or change to 'exec >' if we just want stdout.

Even thou the pipe is removed from the file system in the beginning of the script it will continue to function until the processes finishes. We just can't reference it using the file name after the rm-line.

You are looking for something like the following

ALTER TABLE dbo.doc_exz
ADD CONSTRAINT col_b_def
UNIQUE column_b

MSDN Docs

if you need to change your column output date format just use to_char this well get you a string, not a date.

The following signature will do:

List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);

Spring Data JPA supports a large number of keywords to build a query. IN and AND are among them.

The method Socket.Available will immediately throw a SocketException if the remote system has disconnected/closed the connection.

You can use double splat operator which is available since Ruby 2.0:

h = { a: 1, b: 2 }
h = { **h, c: 3 }
p h
# => {:a=>1, :b=>2, :c=>3}

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

I tend to prefer vi editing mode (since those keystrokes are embedded into my spinal cord now (the brain's not used at all), along with the CTRL-K, CTRL-X from WordStar 3.3 :-). You can use the command line set -o vi to activate it (and set -o emacs to revert).

In Vi, it would be (ESC-K to get the line up first of course) "f5;;B" (without the double quotes).

Of course, you have to understand what's on the line to get away with this. Basically, it's

f5 to find the first occurrence of "5" (in --option5).
;  to find the next one (in --option15).
;  to find the next one (in --option25).
B  to back up to the start of the word.

Let's see if the emacs aficionados can come up with a better solution, less than 5 keystrokes (although I don't want to start a religious war).

Have you thought about whether you'd maybe like to put this horrendously long command into a script? :-)

Actually, I can go one better than that: "3f5B" to find the third occurrence of "5" then back up to the start of the word.

Many people still visit this so here's a very simple diagram to explain it

In github, the easy way is to delete the remote branch in the github UI, under branches tab. You have to make sure remove following settings to make the branch deletable:

1. Not a default branch
2. No opening poll requests.
3. The branch is not protected.

Now recreate it in your local repository to point to the previous commit point. and add it back to remote repo.

git checkout -b master 734c2b9b   # replace with your commit point

Then push the local branch to remote

git push -u origin master

Add back the default branch and branch protection, etc.

class B is only declared but not defined at the beginning, which is what the compiler complains about. The root cause is that in class A's Call Function, you are referencing instance b of type B, which is incomplete and undefined. You can modify source like this without introducing new file(just for sake of simplicity, not recommended in practice):

using namespace std;

class A 
{
public:

    void CallFunction ();
};

class B: public A
{
public:
    virtual void bFunction()
    {
        //stuff done here
    }
};


 // postpone definition of CallFunction here

 void A::CallFunction ()
 {
     B b;
     b.bFunction();
 }

With Symfony, its handling of yaml will indirectly allow you to nest yaml files. The trick is to make use of the parameters option. eg:

common.yml

parameters:
    yaml_to_repeat:
        option: "value"
        foo:
            - "bar"
            - "baz"

config.yml

imports:
    - { resource: common.yml }
whatever:
    thing: "%yaml_to_repeat%"
    other_thing: "%yaml_to_repeat%"

The result will be the same as:

whatever:
    thing:
        option: "value"
        foo:
            - "bar"
            - "baz"
    other_thing:
        option: "value"
        foo:
            - "bar"
            - "baz"

For reference : Why does angularjs include an empty option in select?

The empty option is generated when a value referenced by ng-model doesn't exist in a set of options passed to ng-options. This happens to prevent accidental model selection: AngularJS can see that the initial model is either undefined or not in the set of options and don't want to decide model value on its own.

In short: the empty option means that no valid model is selected (by valid I mean: from the set of options). You need to select a valid model value to get rid of this empty option.

Change your code like this

var MyApp=angular.module('MyApp1',[])
MyApp.controller('MyController', function($scope) {
  $scope.feed = {};

  //Configuration
  $scope.feed.configs = [
    {'name': 'Config 1',
     'value': 'config1'},
    {'name': 'Config 2',
     'value': 'config2'},
    {'name': 'Config 3',
     'value': 'config3'}
  ];
  //Setting first option as selected in configuration select
  $scope.feed.config = $scope.feed.configs[0].value;
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div ng-app="MyApp1">
  <div ng-controller="MyController">
    <input type="text" ng-model="feed.name" placeholder="Name" />
    <!-- <select ng-model="feed.config">
<option ng-repeat="template in configs">{{template.name}}</option>
</select> -->
    <select ng-model="feed.config" ng-options="template.value as template.name for template in feed.configs">
    </select>
  </div>
</div>

Working JSFiddle Demo

UPDATE (Dec 31, 2015)

If You don't want to set a default value and want to remove blank option,

<select ng-model="feed.config" ng-options="template.value as template.name for template in feed.configs">
      <option value="" selected="selected">Choose</option>
</select>

And in JS no need to initialize value.

$scope.feed.config = $scope.feed.configs[0].value;

A quick googling on "perl high resolution timers" gave a reference to Time::HiRes. Maybe that it what you want.

Version 2.11+ use the following:

git stash list

git stash apply n

n is the number stash@{12}

I struggled with this for a little while, and in my case it ended up being the Build Setting under Search Paths called FRAMEWORK_SEARCH_PATHS. It helped that I selected the "Levels" button, which seemed to compare my project, target and "Resolved" settings. I saw that my target setting somehow overrode the default of "$(inherited)", and the overridden value was what XCode "resolved" the setting to be. When I removed the override, which in this case specified the 3.2 sdk, the linker errors went away -- as did some recently appeared warnings about any classes where I called post-4.0 methods.

About those warnings -- I never saw them before I added the MessageUI framework for a recent change. I suspect, but don't know for sure, that when I added that framework, XCode tried to do something clever by adding that override to my target. I didn't do it explicitly at any point. The warnings were,for example, about the URLByAppendingPathComponent method of NSURL, which did not appear until sdk 4.0. Prior to adding the MessageUI framework, I never got that warning. And since I removed the override, I no longer get them.

Instead of using a subquery, you could use two separate queries, one to get the number of rows and the other to select the random rows.

SELECT COUNT(id) FROM users; #id is the primary key

Then, get a random twenty rows.

$start_row = mt_rand(0, $total_rows - 20);

The final query:

SELECT * FROM users ORDER BY name ASC LIMIT $start_row, 20;

If you get your local repo into a complete mess, then a reliable way to throw away local commits in Git is to...

1. Use "git config --get remote.origin.url" to get URL of remote origin
2. Rename local git folder to "my_broken_local_repo"
3. Use "git clone <url_from_1>" to get fresh local copy of remote git repository

In my experience Eclipse handles the world changing around it quite well. However, you may need to select affected projects in Eclipse and clean them to force Eclipse to rebuild them. I guess other IDEs may need a forced rebuild too.

A side benefit of the above procedure is that you will find out if your project relies on local files that were not put into git. If you find you are missing files then you can copy them in from "my_broken_local_repo" and add them to git. Once you have confidence that your new local repo has everything you need then you can delete "my_broken_local_repo".

This also happens to me when an UI label or other UI element is referenced by two variables in the view controller class and I delete one of the variable.

I'm not cool enough for comments. I fixed the plunker from the accepted answer to work for rc2. Nothing fancy, links to the CDN were just broken is all.

Depends on the information you need. For debugging the stack trace & inner exception are useful:

    string message =
        "Exception type " + ex.GetType() + Environment.NewLine +
        "Exception message: " + ex.Message + Environment.NewLine +
        "Stack trace: " + ex.StackTrace + Environment.NewLine;
    if (ex.InnerException != null)
    {
        message += "---BEGIN InnerException--- " + Environment.NewLine +
                   "Exception type " + ex.InnerException.GetType() + Environment.NewLine +
                   "Exception message: " + ex.InnerException.Message + Environment.NewLine +
                   "Stack trace: " + ex.InnerException.StackTrace + Environment.NewLine +
                   "---END Inner Exception";

To sum up:

• float is represented in 32 bits, with 1 sign bit, 8 bits of exponent, and 23 bits of the significand (or what follows from a scientific-notation number: 2.33728*10¹²; 33728 is the significand).

• double is represented in 64 bits, with 1 sign bit, 11 bits of exponent, and 52 bits of significand.

By default, Java uses double to represent its floating-point numerals (so a literal 3.14 is typed double). It's also the data type that will give you a much larger number range, so I would strongly encourage its use over float.

There may be certain libraries that actually force your usage of float, but in general - unless you can guarantee that your result will be small enough to fit in float's prescribed range, then it's best to opt with double.

If you require accuracy - for instance, you can't have a decimal value that is inaccurate (like 1/10 + 2/10), or you're doing anything with currency (for example, representing $10.33 in the system), then use a BigDecimal, which can support an arbitrary amount of precision and handle situations like that elegantly.

in this exmple, we set offsetx to 10 and offsety to 3 (from top left), so the pointer finger will be anchor. fiddle: http://jsfiddle.net/5kxt1j98/ (you can see the difference by moving cursor to top left of container)

Why try to reinvent the wheel? There are more lightweight jQuery slideshow solutions out there then you could poke a stick at, and someone has already done the hard work for you and thought about issues that you might run into (cross-browser compatability etc).

jQuery Cycle is one of my favourite light weight libraries.

What you want to achieve could be done in just

    jQuery("#slideshow").cycle({
    timeout:0, // no autoplay
    fx: 'fade', //fade effect, although there are heaps
    next: '#next',
    prev: '#prev'

Now, this file ("test.py") is in python terminology a "module". We can import it (as long as it can be found in our PYTHONPATH) Note that the current directory is always in PYTHONPATH, so if use_test is being run from the same directory where test.py lives, you're all set:

#file -- use_test.py --

test.test_func()  #prints "Hello!"
print (test.myvar)  #prints 42

from test import test_func #Only import the function directly into current namespace

print(myvar)      #prints 42

There's a lot more you can do than just that through the use of special __init__.py files which allow you to treat multiple files as a single module), but this answers your question and I suppose we'll leave the rest for another time.

One of the best tools is using the Debugging Tools for Windows, and taking a memory dump of the process using adplus, then use windbg and the sos plugin to analyze the process memory, threads, and call stacks.

You can use this method for identifying problems on servers too, after installing the tools, share the directory, then connect to the share from the server using (net use) and either take a crash or hang dump of the process.

Then analyze offline.

You can also run this:

php artisan migrate:status

It makes a db connection connection to get migrations from migrations table. It'll throw an exception if the connection fails.

I have used this in a TryDeleteDirectory function. It was something like this

do
{
    try
    {
        DisableReadOnly(directory);
        directory.Delete(true);
    }
    catch (Exception)
    {
        retryDeleteDirectoryCount++;
    }
} while (Directory.Exists(fullPath) && retryDeleteDirectoryCount < 4);

The React docs says:

Treat this.state as if it were immutable.

Your push will mutate the state directly and that could potentially lead to error prone code, even if you are "resetting" the state again afterwards. F.ex, it could lead to that some lifecycle methods like componentDidUpdate won’t trigger.

The recommended approach in later React versions is to use an updater function when modifying states to prevent race conditions:

this.setState(prevState => ({
  arrayvar: [...prevState.arrayvar, newelement]
}))

The memory "waste" is not an issue compared to the errors you might face using non-standard state modifications.

Alternative syntax for earlier React versions

You can use concat to get a clean syntax since it returns a new array:

this.setState({ 
  arrayvar: this.state.arrayvar.concat([newelement])
})

In ES6 you can use the Spread Operator:

this.setState({
  arrayvar: [...this.state.arrayvar, newelement]
})

The error occurs in 'libcurl', which is the underlying protocol for https upload. Solution is to somehow updgrade libcurl. To get more details about the error, set GIT_CURL_VERBOSE=1

https://confluence.atlassian.com/pages/viewpage.action?pageId=306348908

Meaning of error, as per libcurl doc: CURLE_HTTP_RETURNED_ERROR (22)

This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server returns an error code that is >= 400.

If project is small and will remain small, I would recommend to structure by type (Method 2: ng-book2)

app
|- components
|  |- hero
|  |- hero-list
|  |- villain
|  |- ...
|- services
|  |- hero.service.ts
|  |- ...
|- utils
|- shared

If project will grow you should structure your folders by domain (Method 3: mgechev/angular2-seed)

app
|- heroes
|  |- hero
|  |- hero-list
|  |- hero.service.ts
|- villains
|  |- villain
|  |- ...
|- utils
|- shared

Better to Follow official docs.

I believe this is what you want:

table.groupby('YEARMONTH').CLIENTCODE.nunique()

Example:

In [2]: table
Out[2]: 
   CLIENTCODE  YEARMONTH
0           1     201301
1           1     201301
2           2     201301
3           1     201302
4           2     201302
5           2     201302
6           3     201302

In [3]: table.groupby('YEARMONTH').CLIENTCODE.nunique()
Out[3]: 
YEARMONTH
201301       2
201302       3

What I have found best is a CSRF token and save it in the session for links where you need to verify the referrer.

So if you are generating a FB callback then it would look something like this:

$token = uniqid(mt_rand(), TRUE);
$_SESSION['token'] = $token;
$url = "http://example.com/index.php?token={$token}";

Then the index.php will look like this:

if(empty($_GET['token']) || $_GET['token'] !== $_SESSION['token'])
{
    show_404();
} 

//Continue with the rest of code

I do know of secure sites that do the equivalent of this for all their secure pages.

How can I undo every change made to my directory after the last commit, including deleting added files, resetting modified files, and adding back deleted files?

1. You can undo changes to tracked files with:

   git reset HEAD --hard
   

2. You can remove untracked files with:

   git clean -f
   

3. You can remove untracked files and directories with:

   git clean -fd
   

   but you can't undo change to untracked files.

4. You can remove ignored and untracked files and directories

   git clean -fdx
   

   but you can't undo change to ignored files.

You can also set clean.requireForce to false:

git config --global --add clean.requireForce false

to avoid using -f (--force) when you use git clean.

All the answers here seem to forget about landscape possibilities. If you would like this to work when the device is rotated to a landscape view, then you will face problems.

The trick here is that although the view is aware of the orientation, the keyboard is not. This means in Landscape, the keyboards width is actually its height and visa versa.

To modify Apples recommended way of changing the content insets and get it support landscape orientation, I would recommend using the following:

// Call this method somewhere in your view controller setup code.
- (void)registerForKeyboardNotifications
{
    [[NSNotificationCenter defaultCenter] addObserver:self
            selector:@selector(keyboardWasShown:)
            name:UIKeyboardDidShowNotification object:nil];
   [[NSNotificationCenter defaultCenter] addObserver:self
             selector:@selector(keyboardWillBeHidden:)
             name:UIKeyboardWillHideNotification object:nil];
}

// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification
{
    UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
    CGSize keyboardSize = [[[notif userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    if (orientation == UIDeviceOrientationLandscapeLeft || orientation == UIDeviceOrientationLandscapeRight ) {
        CGSize origKeySize = keyboardSize;
        keyboardSize.height = origKeySize.width;
        keyboardSize.width = origKeySize.height;
    }
    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0);
    scroller.contentInset = contentInsets;
    scroller.scrollIndicatorInsets = contentInsets;

    // If active text field is hidden by keyboard, scroll it so it's visible
    // Your application might not need or want this behavior.
    CGRect rect = scroller.frame;
    rect.size.height -= keyboardSize.height;
    NSLog(@"Rect Size Height: %f", rect.size.height);

    if (!CGRectContainsPoint(rect, activeField.frame.origin)) {
        CGPoint point = CGPointMake(0, activeField.frame.origin.y - keyboardSize.height);
        NSLog(@"Point Height: %f", point.y);
        [scroller setContentOffset:point animated:YES];
    }
}

// Called when the UIKeyboardWillHideNotification is sent    
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    scrollView.contentInset = contentInsets;
    scrollView.scrollIndicatorInsets = contentInsets;
}

The part to pay attention to here is the following:

UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
CGSize keyboardSize = [[[notif userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
if (orientation == UIDeviceOrientationLandscapeLeft || orientation == UIDeviceOrientationLandscapeRight ) {
    CGSize origKeySize = keyboardSize;
    keyboardSize.height = origKeySize.width;
    keyboardSize.width = origKeySize.height;
}

What is does, is detects what orientation the device is in. If it is landscape, it will 'swap' the width and height values of the keyboardSize variable to ensure that the correct values are being used in each orientation.

a = dict(one=1, two=2, three=3)

Providing keyword arguments as in this example only works for keys that are valid Python identifiers. Otherwise, any valid keys can be used.

JSfiddle

function deleteEmpty(obj){
        for(var k in obj)
         if(k == "children"){
             if(obj[k]){
                     deleteEmpty(obj[k]);
             }else{
                   delete obj.children;
              } 
         }
    }

for(var i=0; i< a.children.length; i++){
 deleteEmpty(a.children[i])
}

I know its been a while since the original post but I like using CTE's and this worked for me:

WITH cte_table_a
AS
(
    SELECT [id] [id]
    , MAX([value]) [value]
    FROM table_a
    GROUP BY [id]
)
UPDATE table_b
SET table_b.code = CASE WHEN cte_table_a.[value] IS NOT NULL THEN cte_table_a.[value] ELSE 124 END
FROM table_b
LEFT OUTER JOIN  cte_table_a
ON table_b.id = cte_table_a.id

You can create functions in react components. It is actually regular ES6 class which inherits from React.Component. Just be careful and bind it to the correct context in onClick event:

export default class Archive extends React.Component { 

    saySomething(something) {
        console.log(something);
    }

    handleClick(e) {
        this.saySomething("element clicked");
    }

    componentDidMount() {
        this.saySomething("component did mount");
    }

    render() {
        return <button onClick={this.handleClick.bind(this)} value="Click me" />;
    }
}

I usually shy away from queries from sys* type tables, vendors tend to change these between releases, major or otherwise. What I have always done is to issue the DROP FUNCTION <name> statement and not worry about any SQL error that might come back. I consider that standard procedure in the DBA realm.

In my case the solution was easy. You don't need to declare anything in your web.xml.

Because your project is a web application, the config file should be on WEB-INF/classes after deployment. I advise you to create a Java resource folder (src/main/resources) to do that (best pratice). Another approach is to put the config file in your src/main/java.

Beware with the configuration file name. If you are using XML, the file name is log4j.xml, otherwise log4j.properties.

I've created a new data selector that should enable you to do nested querying and AND conditions. Usage:

$('a:data(category==music,artist.name==Madonna)');

The pattern is:

:data( {namespace} [{operator} {check}]  )

"operator" and "check" are optional. So, if you only have :data(a.b.c) it will simply check for the truthiness of a.b.c.

You can see the available operators in the code below. Amongst them is ~= which allows regex testing:

$('a:data(category~=^mus..$,artist.name~=^M.+a$)');

I've tested it with a few variations and it seems to work quite well. I'll probably add this as a Github repo soon (with a full test suite), so keep a look out!

The code:

(function(){

    var matcher = /\s*(?:((?:(?:\\\.|[^.,])+\.?)+)\s*([!~><=]=|[><])\s*("|')?((?:\\\3|.)*?)\3|(.+?))\s*(?:,|$)/g;

    function resolve(element, data) {

        data = data.match(/(?:\\\.|[^.])+(?=\.|$)/g);

        var cur = jQuery.data(element)[data.shift()];

        while (cur && data[0]) {
            cur = cur[data.shift()];
        }

        return cur || undefined;

    }

    jQuery.expr[':'].data = function(el, i, match) {

        matcher.lastIndex = 0;

        var expr = match[3],
            m,
            check, val,
            allMatch = null,
            foundMatch = false;

        while (m = matcher.exec(expr)) {

            check = m[4];
            val = resolve(el, m[1] || m[5]);

            switch (m[2]) {
                case '==': foundMatch = val == check; break;
                case '!=': foundMatch = val != check; break;
                case '<=': foundMatch = val <= check; break;
                case '>=': foundMatch = val >= check; break;
                case '~=': foundMatch = RegExp(check).test(val); break;
                case '>': foundMatch = val > check; break;
                case '<': foundMatch = val < check; break;
                default: if (m[5]) foundMatch = !!val;
            }

            allMatch = allMatch === null ? foundMatch : allMatch && foundMatch;

        }

        return allMatch;

    };

}());

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

You could use toPrecision() and toFixed() methods of Number type. Check this link How can I format numbers as money in JavaScript?

There is no way you can delete a pull request yourself -- you and the repo owner (and all users with push access to it) can close it, but it will remain in the log. This is part of the philosophy of not denying/hiding what happened during development.

However, if there are critical reasons for deleting it (this is mainly violation of Github Terms of Service), Github support staff will delete it for you.

Whether or not they are willing to delete your PR for you is something you can easily ask them, just drop them an email at [email protected]

UPDATE: Currently Github requires support requests to be created here: https://support.github.com/contact

Regarding to the originally error message

cannot be resolved to absolute file path because it does not reside in the file system

The following code could be helpful, to find the solution for the path problem:

Paths.get("message.txt").toAbsolutePath().toString();

With this you can determine, where the application expects the missing file. You can execute this in the main method of your application.

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

The virtual keyword gives C++ its' ability to support polymorphism. When you have a pointer to an object of some class such as:

class Animal
{
  public:
    virtual int GetNumberOfLegs() = 0;
};

class Duck : public Animal
{
  public:
     int GetNumberOfLegs() { return 2; }
};

class Horse : public Animal
{
  public:
     int GetNumberOfLegs() { return 4; }
};

void SomeFunction(Animal * pAnimal)
{
  cout << pAnimal->GetNumberOfLegs();
}

In this (silly) example, the GetNumberOfLegs() function returns the appropriate number based on the class of the object that it is called for.

Now, consider the function 'SomeFunction'. It doesn't care what type of animal object is passed to it, as long as it is derived from Animal. The compiler will automagically cast any Animal-derived class to a Animal as it is a base class.

If we do this:

Duck d;
SomeFunction(&d);

it'd output '2'. If we do this:

Horse h;
SomeFunction(&h);

it'd output '4'. We can't do this:

Animal a;
SomeFunction(&a);

because it won't compile due to the GetNumberOfLegs() virtual function being pure, which means it must be implemented by deriving classes (subclasses).

Pure Virtual Functions are mostly used to define:

a) abstract classes

These are base classes where you have to derive from them and then implement the pure virtual functions.

b) interfaces

These are 'empty' classes where all functions are pure virtual and hence you have to derive and then implement all of the functions.

I spent measurements (100000 iterations), what fastest way to glue an associative array?

Objective: To obtain a line of 1,000 items, in this format: "key:value,key2:value2"

We have array (for example):

$array = [
    'test0' => 344,
    'test1' => 235,
    'test2' => 876,
    ...
];

Test number one:

Use http_build_query and str_replace:

str_replace('=', ':', http_build_query($array, null, ','));

Average time to implode 1000 elements: 0.00012930955084904

Test number two:

Use array_map and implode:

implode(',', array_map(
        function ($v, $k) {
            return $k.':'.$v;
        },
        $array,
        array_keys($array)
    ));

Average time to implode 1000 elements: 0.0004890081976675

Test number three:

Use array_walk and implode:

array_walk($array,
        function (&$v, $k) {
            $v = $k.':'.$v;
        }
    );
implode(',', $array);

Average time to implode 1000 elements: 0.0003874126245348

Test number four:

Use foreach:

    $str = '';
    foreach($array as $key=>$item) {
        $str .= $key.':'.$item.',';
    }
    rtrim($str, ',');

Average time to implode 1000 elements: 0.00026632803902445

I can conclude that the best way to glue the array - use http_build_query and str_replace

This will for most of the objects for outputting in nodejs console

Solution for python3:

from urllib.request import urlopen

url = 'http://www.python.org'
file = urlopen(url)
html = file.read()
print(html)

Try below piece of code.

this.dataGridView1.RefreshEdit();

You can set executionTimeout in web.config to support the longer execution time.

executionTimeout specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET. MSDN

<httpRuntime  executionTimeout = "300" />

This make execution timeout to five minutes.

Optional Int32 attribute.

Specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET.

This time-out applies only if the debug attribute in the compilation element is False. Therefore, if the debug attribute is True, you do not have to set this attribute to a large value in order to avoid application shutdown while you are debugging. The default is 110 seconds, Reference.

You can set the width in pixels via inline styling:

<input type="text" name="text" style="width: 195px;">

You can also set the width with a visible character length:

<input type="text" name="text" size="35">

I had the same problem since XCode 7.3. For my case, there was a _ in my AppId name and it didn't work even if the AppID was correct : com.mycompany.appname.

I had to edit the AppId in itunes member center to get this warning.

To resolve this bug, I renamed the AppId, generate a new certificate and new provisionning profiles.

Use a JOIN in the DELETE statement.

DELETE p, pa
      FROM pets p
      JOIN pets_activities pa ON pa.id = p.pet_id
     WHERE p.order > :order
       AND p.pet_id = :pet_id

Alternatively you can use...

DELETE pa
      FROM pets_activities pa
      JOIN pets p ON pa.id = p.pet_id
 WHERE p.order > :order
   AND p.pet_id = :pet_id

...to delete only from pets_activities

See this.

For single table deletes, yet with referential integrity, there are other ways of doing with EXISTS, NOT EXISTS, IN, NOT IN and etc. But the one above where you specify from which tables to delete with an alias before the FROM clause can get you out of a few pretty tight spots more easily. I tend to reach out to an EXISTS in 99% of the cases and then there is the 1% where this MySQL syntax takes the day.

Try this, working fine -

$array = json_decode(json_encode($array), true);

you cannot access array (php array) from js try

<?php
$array = array(1,2,3,4,5,6);
echo json_encode($array);
?>

and js

$(document).ready( function() {
    $('#prev').click(function() {
        $.ajax({
            type: 'POST',
            url: 'ajax.php',
            data: 'id=testdata',
            dataType: 'json',
            cache: false,
            success: function(result) {
                $('#content1').html(result[0]);
            },
        });
    });
});

Try this,

 $('.nav-list li').click(function() {

    $('.nav-list li.active').removeClass('active');
    $(this).addClass('active');
});

In your context $(this) will points to the UL element not the Li. Hence you are not getting the expected results.

One option from DOM directly:

$(document).find("title").text();

Tested only on chrome & IE9, but logically should work on all browsers.

Or more generic

var title = document.getElementsByTagName("title")[0].innerHTML;

From Alexandre Gomes Blog I have not tried it. Let me know if it works for you.

function getScrollBarWidth () {
  var inner = document.createElement('p');
  inner.style.width = "100%";
  inner.style.height = "200px";

  var outer = document.createElement('div');
  outer.style.position = "absolute";
  outer.style.top = "0px";
  outer.style.left = "0px";
  outer.style.visibility = "hidden";
  outer.style.width = "200px";
  outer.style.height = "150px";
  outer.style.overflow = "hidden";
  outer.appendChild (inner);

  document.body.appendChild (outer);
  var w1 = inner.offsetWidth;
  outer.style.overflow = 'scroll';
  var w2 = inner.offsetWidth;
  if (w1 == w2) w2 = outer.clientWidth;

  document.body.removeChild (outer);

  return (w1 - w2);
};

When serialising an XML document to a .NET string, the encoding must be set to UTF-16. Strings are stored as UTF-16 internally, so this is the only encoding that makes sense. If you want to store data in a different encoding, you use a byte array instead.

SQL Server works on a similar principle; any string passed into an xml column must be encoded as UTF-16. SQL Server will reject any string where the XML declaration does not specify UTF-16. If the XML declaration is not present, then the XML standard requires that it default to UTF-8, so SQL Server will reject that as well.

Bearing this in mind, here are some utility methods for doing the conversion.

public static string Serialize<T>(T value) {

    if(value == null) {
        return null;
    }

    XmlSerializer serializer = new XmlSerializer(typeof(T));

    XmlWriterSettings settings = new XmlWriterSettings()
    {
        Encoding = new UnicodeEncoding(false, false), // no BOM in a .NET string
        Indent = false,
        OmitXmlDeclaration = false
    };

If you have used them in C, then they are almost same as were in C.

From the manpage of fopen() function : -

• r+ : - Open for reading and writing. The stream is positioned at the beginning of the file.
  
  
• a+ : - Open for reading and writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subse- quent writes to the file will always end up at the then current end of file, irrespective of any intervening fseek(3) or similar.

I agree with somebody's recently deleted post that the differences in performance are so small that, with very very few exceptions, (he got dinged for saying never) you should not make your design decision based upon that.

In your example, where the elements are Objects, the performance difference should be minimal.

If you are dealing with a large number of primitives, an array will offer significantly better performance, both in memory and time.

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").

From the command line, you can type

python setup.py --help

...to get a list of commands. What you are looking to do is...

python setup.py install

If you want to finish and just add a resultCode (without data), you can call setResult(int resultCode) before finish().

For example:

...
if (everything_OK) {
    setResult(Activity.RESULT_OK); // OK! (use whatever code you want)
    finish();
}
else {
   setResult(Activity.RESULT_CANCELED); // some error ...
   finish();
}
...

Then in your calling activity, check the resultCode, to see if we're OK.

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == someCustomRequestCode) {
        if (resultCode == Activity.RESULT_OK) {
            // OK!
        }
        else if (resultCode = Activity.RESULT_CANCELED) {
            // something went wrong :-(
        }
    }
}

Don't forget to call the activity with startActivityForResult(intent, someCustomRequestCode).

here is more simple way without StartCoroutine:

float t = 0f;
float waittime = 1f;

and inside Update/FixedUpdate:

if (t < 0){
    t += Time.deltaTIme / waittime;
    yield return t;
}

Just came across this question, the easiest way to do this is using moment:

You need to install moment and moment-range first:

const Moment = require('moment');
const MomentRange = require('moment-range');
const moment = MomentRange.extendMoment(Moment);

const start = moment()
const end = moment().add(2, 'months')
const range = moment.range(start, end)
const arrayOfDates = Array.from(range.by('days'))
console.log(arrayOfDates)

To safely encrypt large files (>600MB) with openssl smime you'll have to split each file into small chunks:

# Splits large file into 500MB pieces
split -b 500M -d -a 4 INPUT_FILE_NAME input.part.

# Encrypts each piece
find -maxdepth 1 -type f -name 'input.part.*' | sort | xargs -I % openssl smime -encrypt -binary -aes-256-cbc -in % -out %.enc -outform DER PUBLIC_PEM_FILE

For the sake of information, here is how to decrypt and put all pieces together:

# Decrypts each piece
find -maxdepth 1 -type f -name 'input.part.*.enc' | sort | xargs -I % openssl smime -decrypt -in % -binary -inform DEM -inkey PRIVATE_PEM_FILE -out %.dec

# Puts all together again
find -maxdepth 1 -type f -name 'input.part.*.dec' | sort | xargs cat > RESTORED_FILE_NAME

import json

list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]

Write to json File:

with open('/home/ubuntu/test.json', 'w') as fout:
    json.dump(list , fout)

Read Json file:

with open(r"/home/ubuntu/test.json", "r") as read_file:
    data = json.load(read_file)
print(data)
#list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]

Java String class has a built-in-constructor for converting byte array to string.

byte[] byteArray = new byte[] {87, 79, 87, 46, 46, 46};

String value = new String(byteArray, "UTF-8");

React has few lifecycle methods which help in these situations, the lists including but not limited to getInitialState, getDefaultProps, componentWillMount, componentDidMount etc.

In your case and the cases which needs to interact with the DOM elements, you need to wait till the dom is ready, so use componentDidMount as below:

/** @jsx React.DOM */
var List = require('../list');
var ActionBar = require('../action-bar');
var BalanceBar = require('../balance-bar');
var Sidebar = require('../sidebar');
var AppBase = React.createClass({
  componentDidMount: function() {
    ReactDOM.findDOMNode(this).height = /* whatever HEIGHT */;
  },
  render: function () {
    return (
      <div className="wrapper">
        <Sidebar />
        <div className="inner-wrapper">
          <ActionBar title="Title Here" />
          <BalanceBar balance={balance} />
          <div className="app-content">
            <List items={items} />
          </div>
        </div>
      </div>
    );
  }
});

module.exports = AppBase;

As kmcamara discovered, this is exactly the kind of problem that VLOOKUP is intended to solve, and using vlookup is arguably the simplest of the alternative ways to get the job done.

In addition to the three parameters for lookup_value, table_range to be searched, and the column_index for return values, VLOOKUP takes an optional fourth argument that the Excel documentation calls the "range_lookup".

Expanding on deathApril's explanation, if this argument is set to TRUE (or 1) or omitted, the table range must be sorted in ascending order of the values in the first column of the range for the function to return what would typically be understood to be the "correct" value. Under this default behavior, the function will return a value based upon an exact match, if one is found, or an approximate match if an exact match is not found.

If the match is approximate, the value that is returned by the function will be based on the next largest value that is less than the lookup_value. For example, if "12AT8003" were missing from the table in Sheet 1, the lookup formulas for that value in Sheet 2 would return '2', since "12AT8002" is the largest value in the lookup column of the table range that is less than "12AT8003". (VLOOKUP's default behavior makes perfect sense if, for example, the goal is to look up rates in a tax table.)

However, if the fourth argument is set to FALSE (or 0), VLOOKUP returns a looked-up value only if there is an exact match, and an error value of #N/A if there is not. It is now the usual practice to wrap an exact VLOOKUP in an IFERROR function in order to catch the no-match gracefully. Prior to the introduction of IFERROR, no matches were checked with an IF function using the VLOOKUP formula once to check whether there was a match, and once to return the actual match value.

Though initially harder to master, deusxmach1na's proposed solution is a variation on a powerful set of alternatives to VLOOKUP that can be used to return values for a column or list to the left of the lookup column, expanded to handle cases where an exact match on more than one criterion is needed, or modified to incorporate OR as well as AND match conditions among multiple criteria.

Repeating kcamara's chosen solution, the VLOOKUP formula for this problem would be:

   =VLOOKUP(A1,Sheet1!A$1:B$600,2,FALSE)

From Dockerfile reference:

• The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag.

• The ENV instruction sets the environment variable <key> to the value <value>.
  The environment variables set using ENV will persist when a container is run from the resulting image.

So if you need build-time customization, ARG is your best choice.
If you need run-time customization (to run the same image with different settings), ENV is well-suited.

If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable

Given the number of combinations involved, using ENV to set those features at runtime is best here.

But you can combine both by:

• building an image with a specific ARG
• using that ARG as an ENV

That is, with a Dockerfile including:

ARG var
ENV var=${var}

You can then either build an image with a specific var value at build-time (docker build --build-arg var=xxx), or run a container with a specific runtime value (docker run -e var=yyy)

You don't have to struggle any longer, when there exists a way lilke this:

$stmt = $pdo->prepare("SELECT * FROM someTable WHERE col = :val");
$stmt->execute([":val" => $bind]); 

I had this issue on VS2008: I removed the .suo; .ncb; and user project file, then restarted the solution and it fixed the problem for me.

You will need to subscribe to your observables:

this.CountryService.GetCountries()
    .subscribe(countries => {
        this.myGridOptions.rowData = countries as CountryData[]
    })

And, in your html, wherever needed, you can pass the async pipe to it.

it's in <algorithm> and called std::find.

During the preflight request, you should see the following two headers: Access-Control-Request-Method and Access-Control-Request-Headers. These request headers are asking the server for permissions to make the actual request. Your preflight response needs to acknowledge these headers in order for the actual request to work.

For example, suppose the browser makes a request with the following headers:

Origin: http://yourdomain.com
Access-Control-Request-Method: POST
Access-Control-Request-Headers: X-Custom-Header

Your server should then respond with the following headers:

Access-Control-Allow-Origin: http://yourdomain.com
Access-Control-Allow-Methods: GET, POST
Access-Control-Allow-Headers: X-Custom-Header

Pay special attention to the Access-Control-Allow-Headers response header. The value of this header should be the same headers in the Access-Control-Request-Headers request header, and it can not be '*'.

Once you send this response to the preflight request, the browser will make the actual request. You can learn more about CORS here: http://www.html5rocks.com/en/tutorials/cors/

I wrote the Text-IO library, which can deal with the problem of System.console() being null when running an application from within an IDE.

It introduces an abstraction layer similar to the one proposed by McDowell. If System.console() returns null, the library switches to a Swing-based console.

In addition, Text-IO has a series of useful features:

• supports reading values with various data types.
• allows masking the input when reading sensitive data.
• allows selecting a value from a list.
• allows specifying constraints on the input values (format patterns, value ranges, length constraints etc.).

Usage example:

TextIO textIO = TextIoFactory.getTextIO();

String user = textIO.newStringInputReader()
        .withDefaultValue("admin")
        .read("Username");

String password = textIO.newStringInputReader()
        .withMinLength(6)
        .withInputMasking(true)
        .read("Password");

int age = textIO.newIntInputReader()
        .withMinVal(13)
        .read("Age");

Month month = textIO.newEnumInputReader(Month.class)
        .read("What month were you born in?");

textIO.getTextTerminal().println("User " + user + " is " + age + " years old, " +
        "was born in " + month + " and has the password " + password + ".");

In this image you can see the above code running in a Swing-based console.

The URI "file:///android_asset/" points to YourProject/app/src/main/assets/.

Note: android_asset/ uses the singular (asset) and src/main/assets uses the plural (assets).

Suppose you have a file YourProject/app/src/main/assets/web_thing.html that you would like to display in a WebView. You can refer to it like this:

WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/web_thing.html");

The snippet above could be located in your Activity class, possibly in the onCreate method.

Here is a guide to the overall directory structure of an android project, that helped me figure out this answer.

Add the following as toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:fitsSystemWindows="true"
    android:minHeight="?attr/actionBarSize"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    android:background="?attr/colorPrimary">

</android.support.v7.widget.Toolbar>

Then in the layout where you needed

<include layout="@layout/toolbar"/>

Or try http://twitterbootstrapbuttons.w3masters.nl/. It creates css for buttons based on html color input. Add the css after the bootstrap css. It provides three styles of buttons (light, dark and spin).

First error: You're casting a ClientThread as a String for some reason.

Second error: You're not calling remove on your List.

Is is homework? If so, you might want to use the tag.

if you want to follow Android 10 practices to write in storage, check here and if you only want the images to be app specific, here for example if you want to store an image just to be used by your app:

viewModelScope.launch(Dispatchers.IO) {
            getApplication<Application>().openFileOutput(filename, Context.MODE_PRIVATE).use {
                bitmap.compress(Bitmap.CompressFormat.PNG, 50, it)
            }
        }

getApplication is a method to give you context for ViewModel and it's part of AndroidViewModel later if you want to read it:

viewModelScope.launch(Dispatchers.IO) {
            val savedBitmap = BitmapFactory.decodeStream(
                getApplication<App>().openFileInput(filename).readBytes().inputStream()
            )
        }

You can make a bookmark with this as the url:

javascript:
var cached_anchors = $$('a');
for (var i in cached_anchors) {
    var ca = cached_anchors[i];
    if(ca.href.search('sprite') < 0 && ca.href.search('.png') > -1 || ca.href.search('.gif') > -1 || ca.href.search('.jpg') > -1) {
        var a = document.createElement('a');
        a.href = ca.innerHTML;
        a.target = '_blank';

        var img = document.createElement('img');
        img.src = ca.innerHTML;
        img.style.maxHeight = '100px';

        a.appendChild(img);
        document.getElementsByTagName('body')[0].appendChild(a);
    }
}
document.getElementsByTagName('body')[0].removeChild(document.getElementsByTagName('table')[0]);
void(0);

Then just go to chrome://cache and then click your bookmark and it'll show you all the images.

I would turn it into a json object, with the added benefit of keeping the keys if you are using an associative array:

 $stringRepresentation= json_encode($arr);

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

There is no way to retrieve localStorage, sessionStorage or cookie values via javascript in the browser after they've been deleted via javascript.

If what you're really asking is if there is some other way (from outside the browser) to recover that data, that's a different question and the answer will entirely depend upon the specific browser and how it implements the storage of each of those types of data.

For example, Firefox stores cookies as individual files. When a cookie is deleted, its file is deleted. That means that the cookie can no longer be accessed via the browser. But, we know that from outside the browser, using system tools, the contents of deleted files can sometimes be retrieved.

If you wanted to look into this further, you'd have to discover how each browser stores each data type on each platform of interest and then explore if that type of storage has any recovery strategy.

Follow these steps to this problem for all versions of your laravel like laravel 5.5

Step: 1

Rename file .env.example to .env

Step: 2

Go to your Command prompt/terminal and change path to project directory. Generate key for your application. This is unique for every application so don't make copy paste.

Just run the following command. Key will automatically save to your .env file

php artisan key:generate

Extending String native prototype:

if (!String.prototype.contains) {
    Object.defineProperty(String.prototype, 'contains', {
        value(patterns) {
            if (!Array.isArray(patterns)) {
                return false;
            }

            let value = 0;
            for (let i = 0; i < patterns.length; i++) {
                const pattern = patterns[i];
                value = value + this.includes(pattern);
            }
            return (value === 1);
        }
    });
}

Allowing you to do things like:

console.log('Hi, hope you like this option'.toLowerCase().contains(["hello", "hi", "howdy"])); // True

I got this error for a stupid mistake, the variable name in the @PathVariable wasn't matching the one in the @RequestMapping

You could try:

brew update && brew install imagemagick

By pressing one arrow key getch will push three values into the buffer:

• '\033'
• '['
• 'A', 'B', 'C' or 'D'

So the code will be something like this:

if (getch() == '\033') { // if the first value is esc
    getch(); // skip the [
    switch(getch()) { // the real value
        case 'A':
            // code for arrow up
            break;
        case 'B':
            // code for arrow down
            break;
        case 'C':
            // code for arrow right
            break;
        case 'D':
            // code for arrow left
            break;
    }

        call    printf
        mov     eax, 0
        leave 
        ret

#include <stdio.h>
int main(void) {
  register int i = 3;
  i++;
  printf("%d", i);
  return 0;
}

.LC0:
        .string "%d"
main:
        push    rbp
        mov     rbp, rsp
        push    rbx
        sub     rsp, 8
        mov     ebx, 3
        add     ebx, 1
        mov     esi, ebx
        mov     edi, OFFSET FLAT:.LC0
        mov     eax, 0
        call    printf
        add     rsp, 8
        pop     rbx
        pop     rbp
        ret

This forces ebx to be used for the calculation, meaning it needs to be pushed to the stack and restored at the end of the function because it is callee saved. register produces more lines of code and 1 memory write and 1 memory read (although realistically, this could have been optimised to 0 R/Ws if the calculation had been done in esi, which is what happens using C++'s const register). Not using register causes 2 writes and 1 read (although store to load forwarding will occur on the read). This is because the value has to be present and updated directly on the stack so the correct value can be read by address (pointer). register doesn't have this requirement and cannot be pointed to. const and register are basically the opposite of volatile and using volatile will override the const optimisations at file and block scope and the register optimisations at block-scope. const register and register will produce identical outputs because const does nothing on C at block-scope, so only the register optimisations apply.

On clang, register is ignored but const optimisations still occur.

I have done it this way:

<?php 
$PHPtext = "Your PHP alert!";
?>

var JavaScriptAlert = <?php echo json_encode($PHPtext); ?>;
alert(JavaScriptAlert); // Your PHP alert!

• using: You are going to use it.
• namespace: To use what? A namespace.
• std: The std namespace (where features of the C++ Standard Library, such as string or vector, are declared).

After you write this instruction, if the compiler sees string it will know that you may be referring to std::string, and if it sees vector, it will know that you may be referring to std::vector. (Provided that you have included in your compilation unit the header files where they are defined, of course.)

If you don't write it, when the compiler sees string or vector it will not know what you are refering to. You will need to explicitly tell it std::string or std::vector, and if you don't, you will get a compile error.

in addition: for those who have a empty POST variable, don't use this:

name="[levels][level][]"

rather use this (as it is already here in this example):

name="levels[level][]"

little modified Scott's answer:

toCamelCase = (string) ->
  string
    .replace /[\s|_|-](.)/g, ($1) -> $1.toUpperCase()
    .replace /[\s|_|-]/g, ''
    .replace /^(.)/, ($1) -> $1.toLowerCase()

now it replaces '-' and '_' too.

This happened to me recently when I close one Android Studio project and imported another Eclipse project. It seemed to be some bug in Android Studio where it preserves some gradle settings from previously open project and then get confused in the new project.

The solution was extremely simple: Close the project and shut down Android Studio completely, before re-opening it and then import/open the new project. Everything goes smoothly from then on.

You can style checkboxes with a little trickery using the label element an example is below:

And a FIDDLE for the above code. Note that some CSS doesn't work in older versions of browsers, but I'm sure there are some fancy JavaScript examples out there!

You can limit the scope of a playbook by changing the hosts header in its plays without relying on your special host label ‘local’ in your inventory. Localhost does not need a special line in inventories.

- name: run on all except local
  hosts: all:!local

Whilst there are several good answers here, I must point out that it is not good practice to display system exception messages on error pages (which is what I am assuming you want to do). You may inadvertently reveal things you do not wish to do so to malicious users. For example Sql Server exception messages are very verbose and can give the user name, password and schema information of the database when an error occurs. That information should not be displayed to an end user.

I suspect this is wildly inefficient but is quite a simple approach, which worked on a small dataset that I tried it on.

select top 1 field
from table
where field in (select top 5 field from table order by field asc)
order by field desc

This would get the 5th item, change the second top number to get a different nth item

SQL server only (I think) but should work on older versions that do not support ROW_NUMBER().

You cannot directly change a form's validity. If all the descendant inputs are valid, the form is valid, if not, then it is not.

What you should do is to set the validity of the input element. Like so;

addItem.capabilities.$setValidity("youAreFat", false);

Now the input (and so the form) is invalid. You can also see which error causes invalidation.

addItem.capabilities.errors.youAreFat == true;

Eclipse Juno

In Command Shell of Windows, the command pip freeze | xargs pip uninstall -y won't work. So for those of you using Windows, I've figured out an alternative way to do so.

1. Copy all the names of the installed packages of pip from the pip freeze command to a .txt file.
2. Then, go the location of your .txt file and run the command pip uninstall -r *textfile.txt*

Answers given above are perfect but I suggest to use multiple smaller regex rather than a big one.
Splitting the long regex have some advantages:

• easiness to write and read
• easiness to debug
• easiness to add/remove part of regex

Generally this approach keep code easily maintainable.

Having said that, I share a piece of code that I write in Swift as example:

struct RegExp {

    /**
     Check password complexity

     - parameter password:         password to test
     - parameter length:           password min length
     - parameter patternsToEscape: patterns that password must not contains
     - parameter caseSensitivty:   specify if password must conforms case sensitivity or not
     - parameter numericDigits:    specify if password must conforms contains numeric digits or not

     - returns: boolean that describes if password is valid or not
     */
    static func checkPasswordComplexity(password password: String, length: Int, patternsToEscape: [String], caseSensitivty: Bool, numericDigits: Bool) -> Bool {
        if (password.length < length) {
            return false
        }
        if caseSensitivty {
            let hasUpperCase = RegExp.matchesForRegexInText("[A-Z]", text: password).count > 0
            if !hasUpperCase {
                return false
            }
            let hasLowerCase = RegExp.matchesForRegexInText("[a-z]", text: password).count > 0
            if !hasLowerCase {
                return false
            }
        }
        if numericDigits {
            let hasNumbers = RegExp.matchesForRegexInText("\\d", text: password).count > 0
            if !hasNumbers {
                return false
            }
        }
        if patternsToEscape.count > 0 {
            let passwordLowerCase = password.lowercaseString
            for pattern in patternsToEscape {
                let hasMatchesWithPattern = RegExp.matchesForRegexInText(pattern, text: passwordLowerCase).count > 0
                if hasMatchesWithPattern {
                    return false
                }
            }
        }
        return true
    }

    static func matchesForRegexInText(regex: String, text: String) -> [String] {
        do {
            let regex = try NSRegularExpression(pattern: regex, options: [])
            let nsString = text as NSString
            let results = regex.matchesInString(text,
                options: [], range: NSMakeRange(0, nsString.length))
            return results.map { nsString.substringWithRange($0.range)}
        } catch let error as NSError {
            print("invalid regex: \(error.localizedDescription)")
            return []
        }
    }
}

Instead of selecting all the columns in count count(*) you can limit count for one column count(UserName).

You can limit the whole search to one row by using Limit 0,1

SELECT COUNT(UserName)
  FROM TableName
 WHERE UserName = 'User' AND
       Password = 'Pass'
 LIMIT 0, 1

Add ?var1=data1&var2=data2 to the end of url to submit values to the page via GET:

using System.Net;
using System.IO;

string url = "https://www.example.com/scriptname.php?var1=hello";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();

mystring.replace(new RegExp('.', "g"), ' ');

Apple introduced the topLayoutGuide and bottomLayoutGuide as properties of UIViewController way back in iOS 7. They allowed you to create constraints to keep your content from being hidden by UIKit bars like the status, navigation or tab bar. These layout guides are deprecated in iOS 11 and replaced by a single safe area layout guide.

Here is a version that works with 2D arrays, using scipy's cdist function if the user has it, and a simpler distance calculation if they don't.

By default, the output is the index that is closest to the value you input, but you can change that with the output keyword to be one of 'index', 'value', or 'both', where 'value' outputs array[index] and 'both' outputs index, array[index].

For very large arrays, you may need to use kind='euclidean', as the default scipy cdist function may run out of memory.

This is maybe not the absolute fastest solution, but it is quite close.

def find_nearest_2d(array, value, kind='cdist', output='index'):
    # 'array' must be a 2D array
    # 'value' must be a 1D array with 2 elements
    # 'kind' defines what method to use to calculate the distances. Can choose one
    #    of 'cdist' (default) or 'euclidean'. Choose 'euclidean' for very large
    #    arrays. Otherwise, cdist is much faster.
    # 'output' defines what the output should be. Can be 'index' (default) to return
    #    the index of the array that is closest to the value, 'value' to return the
    #    value that is closest, or 'both' to return index,value
    import numpy as np
    if kind == 'cdist':
        try: from scipy.spatial.distance import cdist
        except ImportError:
            print("Warning (find_nearest_2d): Could not import cdist. Reverting to simpler distance calculation")
            kind = 'euclidean'
    index = np.where(array == value)[0] # Make sure the value isn't in the array
    if index.size == 0:
        if kind == 'cdist': index = np.argmin(cdist([value],array)[0])
        elif kind == 'euclidean': index = np.argmin(np.sum((np.array(array)-np.array(value))**2.,axis=1))
        else: raise ValueError("Keyword 'kind' must be one of 'cdist' or 'euclidean'")
    if output == 'index': return index
    elif output == 'value': return array[index]
    elif output == 'both': return index,array[index]
    else: raise ValueError("Keyword 'output' must be one of 'index', 'value', or 'both'")

It seems like you can also use the patch command. Put the diff in the root of the repository and run patch from the command line.

patch -i yourcoworkers.diff

or

patch -p0 -i yourcoworkers.diff

You may need to remove the leading folder structure if they created the diff without using --no-prefix.

If so, then you can remove the parts of the folder that don't apply using:

patch -p1 -i yourcoworkers.diff

The -p(n) signifies how many parts of the folder structure to remove.

More information on creating and applying patches here.

You can also use

git apply yourcoworkers.diff --stat 

to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).

In order to completely remove pip, I believe you have to delete its files from all Python versions on your computer. For me, they are here:

cd /Library/Frameworks/Python.framework/Versions/Current/bin/
cd /Library/Frameworks/Python.framework/Versions/3.3/bin/

You may need to remove the files or the directories located at these file-paths (and more, depending on the number of versions of Python you have installed).

Edit: to find all versions of pip on your machine, use: find / -name pip 2>/dev/null, which starts at its highest level (hence the /) and hides all error messages (that's what 2>/dev/null does). This is my output:

$ find / -name pip 2>/dev/null
/Library/Frameworks/Python.framework/Versions/2.7/bin/pip
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip
/Library/Frameworks/Python.framework/Versions/3.3/bin/pip
/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/pip
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/pip
/Library/Frameworks/Python.framework/Versions/7.1/bin/pip
/Library/Frameworks/Python.framework/Versions/7.1/lib/python2.7/site-packages/pip-1.4.1-py2.7.egg/pip

Unfortunately, no. This feature is not available for facebook albums.

IMHO, most arguments against recursive locks (which are what I use 99.9% of the time over like 20 years of concurrent programming) mix the question if they are good or bad with other software design issues, which are quite unrelated. To name one, the "callback" problem, which is elaborated on exhaustively and without any multithreading related point of view, for example in the book Component software - beyond Object oriented programming.

As soon as you have some inversion of control (e.g. events fired), you face re-entrance problems. Independent of whether there are mutexes and threading involved or not.

class EvilFoo {
  std::vector<std::string> data;
  std::vector<std::function<void(EvilFoo&)> > changedEventHandlers;
public:
  size_t registerChangedHandler( std::function<void(EvilFoo&)> handler) { // ...  
  }
  void unregisterChangedHandler(size_t handlerId) { // ...
  }
  void fireChangedEvent() { 
    // bad bad, even evil idea!
    for( auto& handler : changedEventHandlers ) {
      handler(*this);
    }
  }
  void AddItem(const std::string& item) { 
    data.push_back(item);
    fireChangedEvent();
  }
};

Now, with code like the above you get all error cases, which would usually be named in the context of recursive locks - only without any of them. An event handler can unregister itself once it has been called, which would lead to a bug in a naively written fireChangedEvent(). Or it could call other member functions of EvilFoo which cause all sorts of problems. The root cause is re-entrance. Worst of all, this could not even be very obvious as it could be over a whole chain of events firing events and eventually we are back at our EvilFoo (non- local).

So, re-entrance is the root problem, not the recursive lock. Now, if you felt more on the safe side using a non-recursive lock, how would such a bug manifest itself? In a deadlock whenever unexpected re-entrance occurs. And with a recursive lock? The same way, it would manifest itself in code without any locks.

So the evil part of EvilFoo are the events and how they are implemented, not so much a recursive lock. fireChangedEvent() would need to first create a copy of changedEventHandlers and use that for iteration, for starters.

Another aspect often coming into the discussion is the definition of what a lock is supposed to do in the first place:

• Protect a piece of code from re-entrance
• Protect a resource from being used concurrently (by multiple threads).

The way I do my concurrent programming, I have a mental model of the latter (protect a resource). This is the main reason why I am good with recursive locks. If some (member) function needs locking of a resource, it locks. If it calls another (member) function while doing what it does and that function also needs locking - it locks. And I don't need an "alternate approach", because the ref-counting of the recursive lock is quite the same as if each function wrote something like:

void EvilFoo::bar() {
   auto_lock lock(this); // this->lock_holder = this->lock_if_not_already_locked_by_same_thread())
   // do what we gotta do
   
   // ~auto_lock() { if (lock_holder) unlock() }
}

And once events or similar constructs (visitors?!) come into play, I do not hope to get all the ensuing design problems solved by some non-recursive lock.

You should run the installer as administrator.

1. Run the command prompt as administrator
2. cd directory where msi file is present
3. launch msi file by typing the name in the command prompt
4. You should be happy to see all node commands work from new command prompt shell

The marked answer has the problem that the available packages on the machine that is doing the downloads might be different from the target machine, and thus the package set might be incomplete.

To avoid this and get all dependencies, use the following:

apt-get download $(apt-rdepends <package>|grep -v "^ ")

Some packages returned from apt-rdepends don't exist with the exact name for apt-get download to download (for example, libc-dev). In those cases, filter out those exact names (be sure to use ^<NAME>$ so that other related names, for example libc-dev-bin, that do exist are not skipped).

apt-get download $(apt-rdepends <package>|grep -v "^ " |grep -v "^libc-dev$")

Once downloaded, you can move the .deb files to a machine without Internet and install them:

sudo dpkg -i *.deb

In WinForms and WebForms you can do:

txtName.BackColor = Color.Aqua;

Try postion:sticky on parent element.

In my case i kept getting the same error message. I use fedora. I solved it by doing:

sudo dnf install pycurl

This installed eveything that I needed for it to work.

Here a Kotlin version of the function:

fun getBoundsZoomLevel(bounds: LatLngBounds, mapDim: Size): Double {
        val WORLD_DIM = Size(256, 256)
        val ZOOM_MAX = 21.toDouble();

        fun latRad(lat: Double): Double {
            val sin = Math.sin(lat * Math.PI / 180);
            val radX2 = Math.log((1 + sin) / (1 - sin)) / 2;
            return max(min(radX2, Math.PI), -Math.PI) /2
        }

        fun zoom(mapPx: Int, worldPx: Int, fraction: Double): Double {
            return floor(Math.log(mapPx / worldPx / fraction) / Math.log(2.0))
        }

        val ne = bounds.northeast;
        val sw = bounds.southwest;

        val latFraction = (latRad(ne.latitude) - latRad(sw.latitude)) / Math.PI;

        val lngDiff = ne.longitude - sw.longitude;
        val lngFraction = if (lngDiff < 0) { (lngDiff + 360) } else { (lngDiff / 360) }

        val latZoom = zoom(mapDim.height, WORLD_DIM.height, latFraction);
        val lngZoom = zoom(mapDim.width, WORLD_DIM.width, lngFraction);

        return minOf(latZoom, lngZoom, ZOOM_MAX)
    }

How about with PowerShell?

Code should be looks like this, not tested though

$xlCSV = 6
$Excel = New-Object -Com Excel.Application 
$Excel.visible = $False 
$Excel.displayalerts=$False 
$WorkBook = $Excel.Workbooks.Open("YOUDOC.XLS") 
$Workbook.SaveAs("YOURDOC.csv",$xlCSV) 
$Excel.quit()

Here is a post explaining how to use it

How Can I Use Windows PowerShell to Automate Microsoft Excel?

You can select dropdown option value by name

// deom
jQuery("#option_id").find("option:contains('Monday')").each(function()
{
 if( jQuery(this).text() == 'Monday' )
 {
  jQuery(this).attr("selected","selected");
  }

});

Your question about performance is moot—both functions are very fast. The speed of your code will be determined by what you do with the random numbers.

However it's important you understand the difference in behaviour of those two functions. One does random sampling with replacement, the other does random sampling without replacement.

sum(Santa$Believe)

SQL Server 2012 and 2014 supports IIF(cont,true,false) function. Thus for minimal selection you can use it like

SELECT IIF(first>second, second, first) the_minimal FROM table

While IIF is just a shorthand for writing CASE...WHEN...ELSE, it's easier to write.

Whenever you're confused, I would suggest consulting the Javadoc as the first place for your clarification.

From the javadoc about System, here's what the doc says:

public final class System
extends Object

The System class contains several useful class fields and methods. It cannot be instantiated.
Among the facilities provided by the System class are standard input, standard output, and error output streams; access to externally defined properties and environment variables; a means of loading files and libraries; and a utility method for quickly copying a portion of an array.

Since:
JDK1.0

Regarding System.out

public static final PrintStream out
The "standard" output stream. This stream is already open and ready to accept output data. Typically this stream corresponds to display output or another output destination specified by the host environment or user.
For simple stand-alone Java applications, a typical way to write a line of output data is:

     System.out.println(data)

Java does not have such feature. Instead you can either create regular subclass of your list implementation or create anonymous inner class:

List<String> list = new ArrayList<String>() {
   public String getData() {
       return ""; // add your implementation here. 
   }
};

The problem is to call this method. You can do it "in place":

new ArrayList<String>() {
   public String getData() {
       return ""; // add your implementation here. 
   }
}.getData();

Thought about using the test to pass in the vars? Something like:

Test input would be something like:

{
  "TABLE_NAME": "MyDevTable",
  "PARTITION_KEY": "REGION",
  "SORT_KEY": "COUNTRY"
}

Adjusted your code to accept the inputs:

const AWS = require('aws-sdk');
const docClient = new AWS.DynamoDB.DocumentClient({ apiVersion: '2012-08-10' });

exports.handler = async (event) => {
    const TABLE_NAME = event.TABLE_NAME;
    const PARTITION_KEY = event.PARTITION_KEY;
    const SORT_KEY = event.SORT_KEY;
    let params = {
        TableName: TABLE_NAME,
    };
    console.log(`keys: ${PARTITION_KEY} ${SORT_KEY}`);

    let items = [];
    let data = await docClient.scan(params).promise();
    items = [...items, ...data.Items];
    
    while (typeof data.LastEvaluatedKey != 'undefined') {
        params.ExclusiveStartKey = data.LastEvaluatedKey;

        data = await docClient.scan(params).promise();

Mark Cidade's answer is right - you need to supply a tuple.

However from Python 2.6 onwards you can use format instead of %:

'{0} in {1}'.format(unicode(self.author,'utf-8'),  unicode(self.publication,'utf-8'))

Usage of % for formatting strings is no longer encouraged.

This method of string formatting is the new standard in Python 3.0, and should be preferred to the % formatting described in String Formatting Operations in new code.

After running get_pip.py with python embed you have to modify your pythonXX._pth file. Add Lib\site-packages, to get something like this:

pythonXX.zip
.
Lib\site-packages
# Uncomment to run site.main() automatically
#import site

If you don't you will get this error:

ModuleNotFoundError: No module named 'pip'

or

python-3.8.2-embed-amd64\python.exe: No module named pip

? pip

Clustered basically means that the data is in that physical order in the table. This is why you can have only one per table.

Unclustered means it's "only" a logical order.

This is an expansion of Chase Seibert's answer, with the advantage that it will work for IMAGE and TABLE elements, not just DIVs on Internet Explorer 9.

if (document.createRange) {
    // Internet Explorer 9 and modern browsers
    var r = document.createRange();
    r.setStartBefore(to_copy);
    r.setEndAfter(to_copy);
    r.selectNode(to_copy);
    var sel = window.getSelection();
    sel.addRange(r);
    document.execCommand('Copy');  // Does nothing on Firefox
} else {
    // Internet Explorer 8 and earlier. This stuff won't work
    // on Internet Explorer 9.
    // (unless forced into a backward compatibility mode,
    // or selecting plain divs, not img or table).
    var r = document.body.createTextRange();
    r.moveToElementText(to_copy);
    r.select()
    r.execCommand('Copy');
}

You need to set the value of upload_max_filesize and post_max_size in your php.ini :

; Maximum allowed size for uploaded files.
upload_max_filesize = 40M

; Must be greater than or equal to upload_max_filesize
post_max_size = 40M

After modifying php.ini file(s), you need to restart your HTTP server to use new configuration.

If you can't change your php.ini, you're out of luck. You cannot change these values at run-time; uploads of file larger than the value specified in php.ini will have failed by the time execution reaches your call to ini_set.

See the Description of core php.ini directives.

I like the answer but I think it would be better that you create a global scope function that will allow you to set the scope variable needed.

So in the globalController create

$scope.setScopeVariable = function(variable, value){
    $scope[variable] = value;
}

and then in your html file call it

{{setScopeVariable('myVar', 'whatever')}}

This will then allow you to use $scope.myVar in your respective controller

i've used this

function notIE(){
    var ua = window.navigator.userAgent;
    if (ua.indexOf('Edge/') > 0 || 
        ua.indexOf('Trident/') > 0 || 
        ua.indexOf('MSIE ') > 0){
       return false;
    }else{
        return true;                
    }
}

require will throw a PHP Fatal Error if the file cannot be loaded. (Execution stops)

include produces a Warning if the file cannot be loaded. (Execution continues)

Here is a nice illustration of include and require difference:

From: Difference require vs. include php (by Robert; Nov 2012)

I'm guessing you want to center the box both vertically and horizontally, regardless of browser window size. Since you have a fixed width and height for the box, this should work:

Markup:

<div></div>

CSS:

div {
    height: 200px;
    width: 400px;
    background: black;

    position: fixed;
    top: 50%;
    left: 50%;
    margin-top: -100px;
    margin-left: -200px;
}

The div should remain in the center of the screen even if you resize the browser. Just replace the margin-top and margin-left with half of the height and width of your table.

Edit: Credit goes to CSS-Tricks, where I got the original idea.

When your native query is based on joins, in that case you can get the result as list of objects and process it.

one simple example.

@Autowired
EntityManager em;

    String nativeQuery = "select name,age from users where id=?";   
    Query query = em.createNativeQuery(nativeQuery);
    query.setParameter(1,id);

    List<Object[]> list = query.getResultList();

    for(Object[] q1 : list){

        String name = q1[0].toString();
        //..
        //do something more on 
     }

Find the latest version of chromedriver here. Once downloaded, unzip it at the root of your Python installation, e.g., C:/Program Files/Python-3.5, and that's it.

You don't even need to specify the path anywhere and/or add chromedriver to your path or the like. I just did it on a clean Python installation and that works.

Have a look at the following

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                            new { enctype = "multipart/form-data" }))
{  
    <label for="file">Upload Image:</label> 
    <input type="file" name="file" id="file" style="width: 100%;" /> 
    <input type="submit" value="Upload" class="submit" /> 
}

your controller should have action method which would accept HttpPostedFileBase;

 public ActionResult FileUpload(HttpPostedFileBase file)
    {
        if (file != null)
        {
            string pic = System.IO.Path.GetFileName(file.FileName);
            string path = System.IO.Path.Combine(
                                   Server.MapPath("~/images/profile"), pic); 
            // file is uploaded
            file.SaveAs(path);

            // save the image path path to the database or you can send image 
            // directly to database
            // in-case if you want to store byte[] ie. for DB
            using (MemoryStream ms = new MemoryStream()) 
            {
                 file.InputStream.CopyTo(ms);
                 byte[] array = ms.GetBuffer();
            }

        }
        // after successfully uploading redirect the user
        return RedirectToAction("actionname", "controller name");
    }

Update 1

In case you want to upload files using jQuery with asynchornously, then try this article.

the code to handle the server side (for multiple upload) is;

 try
    {
        HttpFileCollection hfc = HttpContext.Current.Request.Files;
        string path = "/content/files/contact/";

        for (int i = 0; i < hfc.Count; i++)
        {
            HttpPostedFile hpf = hfc[i];
            if (hpf.ContentLength > 0)
            {
                string fileName = "";
                if (Request.Browser.Browser == "IE")
                {
                    fileName = Path.GetFileName(hpf.FileName);
                }
                else
                {
                    fileName = hpf.FileName;
                }
                string fullPathWithFileName = path + fileName;
                hpf.SaveAs(Server.MapPath(fullPathWithFileName));
            }
        }

    }
    catch (Exception ex)
    {
        throw ex;
    }

this control also return image name (in a javascript call back) which then you can use it to display image in the DOM.

UPDATE 2

Alternatively, you can try Async File Uploads in MVC 4.

Although this has an accepted answer, it is not going to effectively work in all cases. For example, I test date validation on a form field I have using the date "10/38/2013", and I got a valid DateObject returned, but the date was what PHP call "overflowed", so that "10/38/2013" becomes "11/07/2013". Makes sense, but should we just accept the reformed date, or force users to input the correct date? For those of us who are form validation nazis, We can use this dirty fix: https://stackoverflow.com/a/10120725/486863 and just return false when the object throws this warning.

The other workaround would be to match the string date to the formatted one, and compare the two for equal value. This seems just as messy. Oh well. Such is the nature of PHP dev.

1. Create a new empty Asp.NET Web Application.
2. Solution Explorer right click on the project root.
3. Choose the menu item Add-> Web Service

var textValue = $("input[type=text]").val()

this will get all values of all text boxes. You can use methods like children, firstchild, etc to hone in. Like by form $('form[name=form1] input[type=text]') Easier to use IDs for targeting elements but if it's purely dynamic you can get all input values then loop through then with JS.
