Regarding the format (mp4 or flv) decide which URL you want to use. Then use this tutorial to download the video and save it into a local directory.

The container div, and sometimes content div, are almost always used to allow for more sophisticated CSS styling. The body tag is special in some ways. Browsers don't treat it like a normal div; its position and dimensions are tied to the browser window.

But a container div is just a div and you can style it with margins and borders. You can give it a fixed width, and you can center it with margin-left: auto; margin-right: auto.

Plus, content, like a copyright notice for example, can go on the outside of the container div, but it can't go on the outside of the body, allowing for content on the outside of a border.

I find that I run into Net::HTTP and Net::FTP problems like this periodically, and when I do, surrounding the call with a timeout() makes all of those issues vanish. So where this will occasionally hang for 3 minutes or so and then raise an EOFError:

res = Net::HTTP.post_form(uri, args)

This always fixes it for me:

res = timeout(120) { Net::HTTP.post_form(uri, args) }

Python is an interesting language in that while there is usually one (or two) "obvious" ways to accomplish any given task, flexibility still exists.

s = "string"
i = 0

print (s + repr(i))

The above code snippet is written in Python3 syntax but the parentheses after print were always allowed (optional) until version 3 made them mandatory.

Hope this helps.

I would use Celery to handle the asynchronous task for you. You'll need to install a broker to serve as your task queue (RabbitMQ and Redis are recommended).

app.py:

from flask import Flask
from celery import Celery

broker_url = 'amqp://guest@localhost'          # Broker URL for RabbitMQ task queue

app = Flask(__name__)    
celery = Celery(app.name, broker=broker_url)
celery.config_from_object('celeryconfig')      # Your celery configurations in a celeryconfig.py

@celery.task(bind=True)
def some_long_task(self, x, y):
    # Do some long task
    ...

@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
    ...
    data = json.loads(request.data)
    text_list = data.get('text_list')
    final_file = audio_class.render_audio(data=text_list)
    some_long_task.delay(x, y)                 # Call your async task and pass whatever necessary variables
    return Response(
        mimetype='application/json',
        status=200
    )

Run your Flask app, and start another process to run your celery worker.

$ celery worker -A app.celery --loglevel=debug

I would also refer to Miguel Gringberg's write up for a more in depth guide to using Celery with Flask.

I partially solved it with:

cd "/path/to/pricipal/folder"

for i in $(ls -d .*/); do sudo ln -s "$PWD"/${i%%/} /home/inukaze/${i%%/}; done

    ln: «/home/inukaze/./.»: can't overwrite a directory
    ln: «/home/inukaze/../..»: can't overwrite a directory

Well, this reduce to me, the major part :)

The get_all_related_fields() method mentioned herein has been deprecated in 1.8. From now on it's get_fields().

>> from django.contrib.auth.models import User
>> User._meta.get_fields()

U can use something like this....

  function (field,value) {

         var newItemOrder= value;
          // Make sure user hasnt already added this item
        angular.forEach(arr, function(item) {
            if (newItemOrder == item.value) {
                arr.splice(arr.pop(item));

            } });

        submitFields.push({"field":field,"value":value});
    };

this is the easiest way that you could print the String by using array!!!

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace arraypracticeforstring
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] arr = new string[3] { "Snehal", "Janki", "Thakkar" };

            foreach (string item in arr)
            {
                Console.WriteLine(item.ToString());
            }
            Console.ReadLine();
        }
    }
}

If you use primeng and Angular 6 or above there is the p-inputMask component. It prevents alpha typing AND negative values https://www.primefaces.org/primeng/#/inputmask

This doesn't work in IE8 but might be an option to consider. It is primarily useful if you do not want to specify a width.

.element
{
  position: absolute;
  left: 50%;
  transform: translateX(-50%);
}

I'd also like to know the "right" way, but in the meantime, you can do this:

git show mytag | head -1    

You should checkout the Date object.

In particular, you can look at the getHours() method for the Date object.

getHours() return the time from 0 - 23, so make sure to deal with it accordingly. I think 0-23 is a bit more intuitive since military time runs from 0 - 23, but it's up to you.

With that in mind, the code would be something along the lines of:

var date = new Date();
var current_hour = date.getHours();

SELECT q'[Alex's Tea Factory]' FROM DUAL

This centers the "A" below the image:

<div style="text-align:center">
  <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/opentoselect.gif" />
  <br />
  A
</div>

That is ASP.Net and it would render the HTML as:

<div style="text-align:center">
<img id="Image1" src="Images/opentoselect.gif" style="border-width:0px;" />
<br />
A
</div>

Here's my timer for 5 minutes:

var start = moment("5:00", "m:ss");
var seconds = start.minutes() * 60;
this.interval = setInterval(() => {
    this.timerDisplay = start.subtract(1, "second").format("m:ss");
    seconds--;
    if (seconds === 0) clearInterval(this.interval);
}, 1000);

To specify a classpath for a single Java process, you can add a classpath option when you run the Java command.

In you command line. Use java -cp "path/to/your/jar:." main rather than just java main

The option tells Java where to search for libraries.

Have you thought about this:

try {
    ko.applyBindings(PersonListViewModel);
}
catch (err) {
    console.log(err.message);
}

I came up with this because in Knockout, i found this code

    var alreadyBound = ko.utils.domData.get(node, boundElementDomDataKey);
    if (!sourceBindings) {
        if (alreadyBound) {
            throw Error("You cannot apply bindings multiple times to the same element.");
        }
        ko.utils.domData.set(node, boundElementDomDataKey, true);
    }

So to me its not really an issue that its already bound, its that the error was not caught and dealt with...

The python error says that wordInput is not an iterable -> it is of NoneType.

If you print wordInput before the offending line, you will see that wordInput is None.

Since wordInput is None, that means that the argument passed to the function is also None. In this case word. You assign the result of pickEasy to word.

The problem is that your pickEasy function does not return anything. In Python, a method that didn't return anything returns a NoneType.

I think you wanted to return a word, so this will suffice:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

Thanks to kind and patient help from golang-nuts, recipe is the following:

1) One needs to compile Go compiler for different target platforms and architectures. This is done from src folder in go installation. In my case Go installation is located in /usr/local/go thus to compile a compiler you need to issue make utility. Before doing this you need to know some caveats.

There is an issue about CGO library when cross compiling so it is needed to disable CGO library.

Compiling is done by changing location to source dir, since compiling has to be done in that folder

cd /usr/local/go/src

then compile the Go compiler:

sudo GOOS=windows GOARCH=386 CGO_ENABLED=0 ./make.bash --no-clean

You need to repeat this step for each OS and Architecture you wish to cross compile by changing the GOOS and GOARCH parameters.

If you are working in user mode as I do, sudo is needed because Go compiler is in the system dir. Otherwise you need to be logged in as super user. On Mac you may need to enable/configure SU access (it is not available by default), but if you have managed to install Go you possibly already have root access.

2) Once you have all cross compilers built, you can happily cross compile your application by using the following settings for example:

GOOS=windows GOARCH=386 go build -o appname.exe appname.go

GOOS=linux GOARCH=386 CGO_ENABLED=0 go build -o appname.linux appname.go

Change the GOOS and GOARCH to targets you wish to build.

If you encounter problems with CGO include CGO_ENABLED=0 in the command line. Also note that binaries for linux and mac have no extension so you may add extension for the sake of having different files. -o switch instructs Go to make output file similar to old compilers for c/c++ thus above used appname.linux can be any other extension.

One thing that caused me a massive headache when using this code (might affect others and I wish that somebody had left a comment like this one here for me to read):

• My aim is to create a dynamic access dashboard, which requires that its linked tables be updated.
• I use the copy methods described above to replace the existing linked CSVs with an updated version of them.
• Running the above code manually from a module worked fine.
• Running identical code from a form linked to the CSV data had runtime error 70 (Permission denied), even tho the first step of my code was to close that form (which should have unlocked the CSV file so that it could be overwritten).
• I now believe that despite the form being closed, it keeps the outdated CSV file locked while it executes VBA associated with that form.

My solution will be to run the code (On timer event) from another hidden form that opens with the database.

You can directly export the query result with export option in the result grig. This export has various options to export. I think this will work.

As Answered here

Use below code :

TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();

In AndroidManifest.xml, give the following permission:

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

But remember, this code does not always work, since Cell phone number is dependent on the SIM Card and the Network operator / Cell phone carrier.

Also, try checking in Phone--> Settings --> About --> Phone Identity, If you are able to view the Number there, the probability of getting the phone number from above code is higher. If you are not able to view the phone number in the settings, then you won't be able to get via this code!

Suggested Workaround:

1. Get the user's phone number as manual input from the user.
2. Send a code to the user's mobile number via SMS.
3. Ask user to enter the code to confirm the phone number.
4. Save the number in sharedpreference.

Do the above 4 steps as one time activity during the app's first launch. Later on, whenever phone number is required, use the value available in shared preference.

var logFile = File.ReadAllLines(LOG_PATH);
var logList = new List<string>(logFile);

Since logFile is an array, you can pass it to the List<T> constructor. This eliminates unnecessary overhead when iterating over the array, or using other IO classes.

Actual constructor implementation:

public List(IEnumerable<T> collection)
{
        ...
        ICollection<T> c = collection as ICollection<T>;
        if( c != null) {
            int count = c.Count;
            if (count == 0)
            {
                _items = _emptyArray;
            }
            else {
                _items = new T[count];
                c.CopyTo(_items, 0);
                _size = count;
            }
        }   
        ...
} 

What's the big deal with this.. The cleanest way to do this is

var currentDate=new Date().toLocaleString().slice(0,10);

As other option, you can do something like below

Group   Valuation   amount
    0   BKB Tube    156
    1   BKB Tube    143
    2   BKB Tube    67
    3   BAC Tube    176
    4   BAC Tube    39
    5   JDK Tube    75
    6   JDK Tube    35
    7   JDK Tube    155
    8   ETH Tube    38
    9   ETH Tube    56

Below script, you can use for above data

import pandas as pd    
data = pd.read_csv("daata1.csv")
bytreatment = data.groupby('Group')
bytreatment['amount'].sum()

Oracle does not have a simple database model like MySQL or MS SQL Server. I find the closest thing is to query the tablespaces and the corresponding users within them.

For example, I have a DEV_DB tablespace with all my actual 'databases' within them:

SQL> SELECT TABLESPACE_NAME FROM USER_TABLESPACES;

Resulting in:

SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS
EXAMPLE
DEV_DB

It is also possible to query the users in all tablespaces:

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS;

Or within a specific tablespace (using my DEV_DB tablespace as an example):

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS where DEFAULT_TABLESPACE = 'DEV_DB';

ROLES DEV_DB
DATAWARE DEV_DB
DATAMART DEV_DB
STAGING DEV_DB

The only thing that worked for me (with an existing project on a fresh install of macOS) was:

"File" > "Sync Project with Gradle Files"

This was odd to me since building the project succeeded with no errors or log messages, but I couldn’t run the project and there was nothing Android in the Tools menu.

I had already tried creating a new Android project and running that. It didn't help with my existing project.

This is easy to do, you can render the report as a PDF, and save the resulting byte array as a PDF file on disk. To do this in the background, that's more a question of how your app is written. You can just spin up a new thread, or use a BackgroundWorker (if this is a WinForms app), etc. There, of course, may be multithreading issues to be aware of.

Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string filenameExtension;

byte[] bytes = reportViewer.LocalReport.Render(
    "PDF", null, out mimeType, out encoding, out filenameExtension,
    out streamids, out warnings);

using (FileStream fs = new FileStream("output.pdf", FileMode.Create))
{
    fs.Write(bytes, 0, bytes.Length);
}

Got the same issue, turned out that the private key to the certificate had no permission.
To fix - open the certifacte management, find your certificate, right click -> Manage Private Keys and then in security on top be sure that your user is added and given permissions, that fixed it for me.

My situation was not covered by any of the above answers. I found the following: MSDN article on threading that explains that when stuck in some primitive native threading operations, the debugger can't access the data. As an example, when a thread is sitting on Task.Wait(), this comes up.

$('img.conversation_img[alt="example"]')
    .each(function(){
         alert($(this).attr('src'))
    });

This will display src attributes of all images of class 'conversation_img' with alt='example'

I am using this interceptors to get the error response.

const HttpClient = axios.create({
  baseURL: env.baseUrl,
});

HttpClient.interceptors.response.use((response) => {
  return response;
}, (error) => {
  return Promise.resolve({ error });
});

Use the true or false commands immediately before your return, then return with no parameters. The return will automatically use the value of your last command.

Providing arguments to return is inconsistent, type specific and prone to error if you are not using 1 or 0. And as previous comments have stated, using 1 or 0 here is not the right way to approach this function.

#!/bin/bash

function test_for_cat {
    if [ $1 = "cat" ];
    then
        true
        return
    else
        false
        return
    fi
}

for i in cat hat;
do
    echo "${i}:"
    if test_for_cat "${i}";
    then
        echo "- True"
    else
        echo "- False"
    fi

@Xeon06, nice but just as a fyi for those that read this thread and tried like me... when returning the array from php => json_encode($theArray). converts to a string which to me isn't easy to manipulate esp for soft js users like myself.

Inside js, you are trying to get the array values and/or keys of the array u r better off using JSON.parse as in var jsArray = JSON.parse(data) where data is return array from php. the json encoded string is converted to js object that can now be manipulated easily.

e.g. foo={one:1, two:2, three:3} - gotten after JSON.parse

for (key in foo){ console.log("foo["+ key +"]="+ foo[key]) } - prints to ur firebug console. voila!

You can make a class for your global variable and then export this class like this:

export class CONSTANT {
    public static message2 = [
        { "NAME_REQUIRED": "Name is required" }
    ]

    public static message = {
        "NAME_REQUIRED": "Name is required",
    }
}

After creating and exporting your CONSTANT class, you should import this class in that class where you want to use, like this:

import { Component, OnInit                       } from '@angular/core';
import { CONSTANT                                } from '../../constants/dash-constant';


@Component({
  selector   : 'team-component',
  templateUrl: `../app/modules/dashboard/dashComponents/teamComponents/team.component.html`,
})

export class TeamComponent implements OnInit {
  constructor() {
    console.log(CONSTANT.message2[0].NAME_REQUIRED);
    console.log(CONSTANT.message.NAME_REQUIRED);
  }

  ngOnInit() {
    console.log("oninit");
    console.log(CONSTANT.message2[0].NAME_REQUIRED);
    console.log(CONSTANT.message.NAME_REQUIRED);
  }
}

You can use this either in constructor or ngOnInit(){}, or in any predefine methods.

TLDR - delete the app from the device and run again.

In my case :
1. I compiled and run the app on the iPhone device.
2. I open in the setting the Capabilities and turn on the iCloud
3. Then I try to run the app again, boom, error : "App installation failed This application's application-identifier entitlement does not match that of the installed application. These values must match for an upgrade to be allowed.

4.Then I deleted to app from the iPhone (after I read the answers here)
5.Everything works O.K

You can also use head and tail:

In [29]: pd.concat([df.head(1), df.tail(1)])
Out[29]:
   a  b
0  1  a
3  4  d

Concurrency can involve tasks run simultaneously or not (they can indeed be run in separate processors/cores but they can as well be run in "ticks"). What is important is that concurrency always refer to doing a piece of one greater task. So basically it's a part of some computations. You have to be smart about what you can do simultaneously and what not to and how to synchronize.

Parallelism means that you're just doing some things simultaneously. They don't need to be a part of solving one problem. Your threads can, for instance, solve a single problem each. Of course synchronization stuff also applies but from different perspective.

Your code has lots of errors.

• You are mixing up dm$Day and dm$day. Probably not the same thing
• Your column headings are Date and Visits. So you would access them (I'm guessing) as dm$Date and dm$Visits
• In the date field you have %Y-%m-%d this should be %m/%d/%Y

The following code should plot what you want:

dm$newday = as.Date(dm$Date, "%m/%d/%Y")
plot(dm$newday, dm$Visits)

What ultimately worked for me was the following steps:

1. Configure the Environment Injector Plugin: https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin
2. Goto to the /job//configure screen
3. In Build Environment section check "Inject environment variables to the build process"
4. In "Properties Content" specified: TZ=America/New_York

DEMO

Recommended to use eventListener

// Should only be triggered on first page load
console.log('ho');

window.addEventListener("load", function() {
  document.getElementById('my-form').addEventListener("submit", function(e) {
    e.preventDefault(); // before the code
    /* do what you want with the form */

    // Should be triggered on form submit
    console.log('hi');
  })
});

<form id="my-form">
  <input type="text" name="in" value="some data" />
  <button type="submit">Go</button>
</form>

but if you do not need more than one listener you can use onload and onsubmit

// Should only be triggered on first page load
console.log('ho');

window.onload = function() {
  document.getElementById('my-form').onsubmit = function() {
    /* do what you want with the form */

    // Should be triggered on form submit
    console.log('hi');
    // You must return false to prevent the default form behavior
    return false;
  }
}

    <form id="my-form">
      <input type="text" name="in" value="some data" />
      <button type="submit">Go</button>

Hey It's very simple see this

@OLD_GUEST_NAME = d.GUEST_NAME from deleted d;

this variable will store your old deleted value and then you can insert it where you want.

for example-

Create trigger testupdate on test for update, delete
  as
declare @tableid varchar(50);
declare @testid varchar(50);
declare @newdata varchar(50);
declare @olddata varchar(50);


select @tableid = count(*)+1 from audit_test
select @testid=d.tableid from inserted d;
select @olddata = d.data from deleted d;
select @newdata = i.data from inserted i;

insert into audit_test (tableid, testid, olddata, newdata) values (@tableid, @testid, @olddata, @newdata)

go

I don't have experience with ksh, but I have used both bash and zsh. I prefer zsh over bash because of its support for very powerful file globbing, variable expansion modifiers, and faster tab completion.

Here's a quick intro: http://friedcpu.wordpress.com/2007/07/24/zsh-the-last-shell-youll-ever-need/

from string import rstrip

with open('bvc.txt') as f:
    alist = map(rstrip, f)

Nota Bene: rstrip() removes the whitespaces, that is to say : \f , \n , \r , \t , \v , \x and blank ,
but I suppose you're only interested to keep the significant characters in the lines. Then, mere map(strip, f) will fit better, removing the heading whitespaces too.

If you really want to eliminate only the NL \n and RF \r symbols, do:

with open('bvc.txt') as f:
    alist = f.read().splitlines()

splitlines() without argument passed doesn't keep the NL and RF symbols (Windows records the files with NLRF at the end of lines, at least on my machine) but keeps the other whitespaces, notably the blanks and tabs.

.

with open('bvc.txt') as f:
    alist = f.read().splitlines(True)

has the same effect as

with open('bvc.txt') as f:
    alist = f.readlines()

that is to say the NL and RF are kept

As a completion to Gustavo Bezerra's answer:

If you want each histogram to be normalized (normed for mpl<=2.1 and density for mpl>=3.1) you cannot just use normed/density=True, you need to set the weights for each value instead:

import numpy as np
import matplotlib.pyplot as plt

x = np.random.normal(1, 2, 5000)
y = np.random.normal(-1, 3, 2000)
x_w = np.empty(x.shape)
x_w.fill(1/x.shape[0])
y_w = np.empty(y.shape)
y_w.fill(1/y.shape[0])
bins = np.linspace(-10, 10, 30)

plt.hist([x, y], bins, weights=[x_w, y_w], label=['x', 'y'])
plt.legend(loc='upper right')
plt.show()

As a comparison, the exact same x and y vectors with default weights and density=True:

Here are brief list:

• JQuery with JSON stuff. (http://www.w3schools.com/xml/xml_http.asp)

• $_SESSION - probably best way

• Custom cookie - will not *always* work.

• HTTP headers - some proxy can block it.

• database such MySQL, Postgres or something else such Redis or Memcached (e.g. similar to home-made session, "locked" by IP address)

• APC - similar to database, will not *always* work.

• HTTP_REFERRER

• URL hash parameter , e.g. http://domain.com/page.php#param - you will need some JavaScript to collect the hash. - gmail heavy use this.

Here's my non-silly example, (from Stevens APITUE) for Unix system calls which may be interrupted by a signal.

restart:
    if (system_call() == -1) {
        if (errno == EINTR) goto restart;

        // handle real errors
    }

The alternative is a degenerate loop. This version reads like English "if the system call was interrupted by a signal, restart it".

If you specify the disabled attribute then the value you give it must be disabled. (In HTML 5 you may leave off everything except the attribute value. In HTML 4 you may leave off everything except the attribute name.)

If you do not want the control to be disabled then do not specify the attribute at all.

Disabled:

<input type="checkbox" disabled>
<input type="checkbox" disabled="disabled">

Enabled:

<input type="checkbox">

Invalid (but usually error recovered to be treated as disabled):

<input type="checkbox" disabled="1">
<input type="checkbox" disabled="true">
<input type="checkbox" disabled="false">

So, without knowing your template language, I guess you are looking for:

<td><input type="checkbox" name="repriseCheckBox" {checkStat == 1 ? disabled : }/></td>

Guys found the perfect way to monitor ALL traffic that is flowing locally between requests from my machine to my machine:

1. Install Wireshark

2. When you need to capture traffic that is flowing from a localhost to a localhost then you will struggle to use wireshark as this only monitors incoming traffic on the network card. The way to do this is to add a route to windows that will force all traffic through a gateway and this be captured on the network interface.

   To do this, add a route with <ip address> <gateway>:

    cmd> route add 192.168.20.30 192.168.20.1
   

3. Then run a capture on wireshark (make sure you select the interface that has bytes flowing through it) Then filter.

The newly added routes will come up in black. (as they are local addresses)

Don't do this, but this is how you would do it:

$(".overdue").each(function() { 
    alert("Your book is overdue"); 
});

The reason I say "don't do it" is because nothing is more annoying to users, in my opinion, than repeated pop-ups that cannot be stopped. Instead, just use the length property and let them know that "You have X books overdue".

If you really need it inline, for example because you are loading some user-defined colors dynamically, you can always add a <style> element right before your content.

<style>#project-slide-1:before { color: #ff0000; }</style>
<div id="project-slide-1" class="project-slide"> ... </div>

Example use case with PHP and some (wordpress inspired) dummy functions:

<style>#project-slide-<?php the_ID() ?>:before { color: <?php the_field('color') ?>; }</style>
<div id="project-slide-<?php the_ID() ?>" class="project-slide"> ... </div>

Since HTML 5.2 it is valid to place style elements inside the body, although it is still recommend to place style elements in the head.

Reference: https://www.w3.org/TR/html52/document-metadata.html#the-style-element

I am using windows machine.

https://github.com/JedWatson/classnames

You can do stuff like

classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ 'foo-bar': true }); // => 'foo-bar'
classNames({ 'foo-bar': false }); // => ''
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'

// lots of arguments of various types
classNames('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'

// other falsy values are just ignored
classNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'

or use it like this

var btnClass = classNames('btn', this.props.className, {
  'btn-pressed': this.state.isPressed,
  'btn-over': !this.state.isPressed && this.state.isHovered
});

One thing i would like to add In a signed int, which is the default value in mysql , 1 bit will be used to represent sign. -1 for negative and 0 for positive. So if your application insert only positive value it should better specify unsigned.

As mentioned in the React documentation, there is no guarantee of setState being fired synchronously, so your console.log may return the state prior to it updating.

Michael Parker mentions passing a callback within the setState. Another way to handle the logic after state change is via the componentDidUpdate lifecycle method, which is the method recommended in React docs.

Generally we recommend using componentDidUpdate() for such logic instead.

This is particularly useful when there may be successive setStates fired, and you would like to fire the same function after every state change. Rather than adding a callback to each setState, you could place the function inside of the componentDidUpdate, with specific logic inside if necessary.

// example
componentDidUpdate(prevProps, prevState) {
  if (this.state.value > prevState.value) {
    this.foo();  
  }
}

Sounds like you're looking for rbind:

> a<-matrix(nrow=10,ncol=5)
> b<-matrix(nrow=20,ncol=5)
> dim(rbind(a,b))
[1] 30  5

Similarly, cbind stacks the matrices horizontally.

I am not entirely sure what you mean by the last question ("Can I do this for matrices of different rows and columns.?")

Try installing sqlite like this if you are using FreeBSD.

pkg install py27-sqlite3-2.7.10_6

Another possibility is using java.nio.ByteBuffer.

Something like

ByteBuffer bb = ByteBuffer.allocate(a.length + b.length + c.length);
bb.put(a);
bb.put(b);
bb.put(c);
byte[] result = bb.array();

// or using method chaining:

byte[] result = ByteBuffer
        .allocate(a.length + b.length + c.length)
        .put(a).put(b).put(c)
        .array();

Note that the array must be appropriately sized to start with, so the allocation line is required (as array() simply returns the backing array, without taking the offset, position or limit into account).

In a linked question, there's some Objective-C code to get the mime type for a file URL. I've created a Swift extension based on that Objective-C code to get the mime type:

import Foundation
import MobileCoreServices

extension URL {
    var mimeType: String? {
        guard self.pathExtension.count != 0 else {
            return nil
        }

        let pathExtension = self.pathExtension as CFString
        if let preferredIdentifier = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension, nil) {
            guard let mimeType = UTTypeCopyPreferredTagWithClass(preferredIdentifier.takeRetainedValue(), kUTTagClassMIMEType) else {
                return nil
            }
            return mimeType.takeRetainedValue() as String
        }

        return nil
    }
}

In conclusion:

distutils doesn't support install_requires or entry_points, setuptools does.

change from distutils.core import setup in setup.py to from setuptools import setup or refactor your setup.py to use only distutils features.

I came here because I hadn't realized entry_points was only a setuptools feature.

If you are here wanting to convert setuptools to distutils like me:

1. remove install_requires from setup.py and just use requirements.txt with pip
2. change entry_points to scripts (doc) and refactor any modules relying on entry_points to be full scripts with shebangs and an entry point.

Only want to clone the structure of table:

CREATE TABLE foo SELECT * FROM bar WHERE 1 = 2;

Also wants to copy the data:

CREATE TABLE foo as SELECT * FROM bar;

To convert date to local date use toLocaleDateString() method.

var date = (new Date(str)).toLocaleDateString(defaultlang, options);

To convert time to local time use toLocaleTimeString() method.

var time = (new Date(str)).toLocaleTimeString(defaultlang, options);

Another option would be to use the jQuery Transit Framework to handle your CSS3 transitions. The transitions/effects perform well on mobile devices and you don't have to add a single line of messy CSS3 transitions in your CSS file in order to do the animation effects.

Here is an example that will transition an element's opacity to 0 when you click on it and will be removed once the transition is complete:

$("#element").click( function () {
    $('#element').transition({ opacity: 0 }, function () { $(this).remove(); });
});

I was going to bitch and moan about Java, but obviously it isn't THAT bad and that would have amounted to trolling, and besides, I just remembered something far worse:

Magic II.

It just barely qualified as a language. Really, it could be more accurately described as a pre-SQL database system with a data driven programming model. It was based on the astute observation that almost everything you ever do with database tables involves doing something before you start iterating on the data, then iterating on the data, and then maybe doing something after you're done.

"Programming" Magic involves filling in fields in tables that describe those three phases of a program's life. It also had a text mode screen designer that tied in with this whole mess. A trained Magic user could knock out reports and data entry screens at a reasonably fast pace, which made management happy.

The problem for me was that the language had very minimal abstraction facilities. You could define routines that you could call from other routines. That's it. No data structures other than database tables, no in-memory arrays (you could define new tables, though!)

No hash tables, no way to organize variables (which the language did support) in any meaningful way. No lists. Nothing. Of course, no classes or anything resembling an object model, but honestly - I could live without that. And I did.

Worse yet, the "program" had bits and pieces that were hidden away in fields that you had to zoom into to be able to see - certain expressions, etc. So you could never just read a screen of code and know what it did.

This thing took data driven programming to its ultimate, sad apex. It's an obsession, manifested in a programming tool. I was glad to put that miserable piece of junk behind me.

Recently, I met a former co-worker who worked with me while I was using Magic. It's been almost 20 years since I've done that, but she was all too happy to tell me how she was tasked with maintaining one of my projects, and that she declared defeat when she found a recursive procedure in there somewhere. She had never seen anyone implement recursion in Magic. No one ever has. It was uncharted territory. I don't think anyone realized the tool was capable of recursion.

The project had to be rewritten in a hurry, before it caused someone's brain to explode.

This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {

    fs.readFile(filename, "utf8", function(err, data) {
        if (err) {
            // may be filename does not exists?
            resp.writeHead(404, {
                'Content-Type' : 'text/html'
            });
            // log this error into browser
            resp.write(err.toString());
            resp.end();
        } else {

            resp.writeHead(200, {
                "Content-Type": "text/html"
            });      
            resp.write(data.toString());
            resp.end();
        }
    });
}

I have a suggestion but not a solution. If some of your columns have a larger data sets then you should try with following

SELECT *, LEFT(col1, 0) AS col1, LEFT(col2, 0) as col2 FROM table

See http://slkpg.byethost7.com/instance.html for yet another twist on OOP in C. It emphasizes instance data for reentrancy using just native C. Multiple inheritance is done manually using function wrappers. Type safety is maintained. Here is a small sample:

typedef struct _peeker
{
    log_t     *log;
    symbols_t *sym;
    scanner_t  scan;            // inherited instance
    peek_t     pk;
    int        trace;

    void    (*push) ( SELF *d, symbol_t *symbol );
    short   (*peek) ( SELF *d, int level );
    short   (*get)  ( SELF *d );
    int     (*get_line_number) ( SELF *d );

} peeker_t, SlkToken;

#define push(self,a)            (*self).push(self, a)
#define peek(self,a)            (*self).peek(self, a)
#define get(self)               (*self).get(self)
#define get_line_number(self)   (*self).get_line_number(self)

    return  d->scan.line_number;

sed -i '/pattern/d' file

Use 'd' to delete a line. This works at least with GNU-Sed.

If your Sed doesn't have the option, to change a file in place, maybe you can use an intermediate file, to store the modification:

sed '/pattern/d' file > tmpfile && mv tmpfile file

Writing directly to the source usually doesn't work: sed '/pattern/d' file > file so make a copy before trying out, if you doubt it.

From Django documentation for url

url(regex, view, kwargs=None, name=None) This function is an alias to django.urls.re_path(). It’s likely to be deprecated in a future release.

Key difference between path and re_path is that path uses route without regex

You can use re_path for complex regex calls and use just path for simpler lookups

Always use UTC:

For example I have a schedule component that takes in one parameter DATETIME. When I call this using a GET verb I use the following format where my incoming parameter name is scheduleDate.

Example:
https://localhost/api/getScheduleForDate?scheduleDate=2003-11-21T01:11:11Z

ifeq ($(GCC_MINOR), 4)
    CFLAGS += -fno-strict-overflow
endif
ifeq ($(GCC_MINOR), 5)
    CFLAGS += -fno-strict-overflow
endif

Another you can consider using in this case is:

GCC42_OR_LATER = $(shell $(CXX) -v 2>&1 | $(EGREP) -c "^gcc version (4.[2-9]|[5-9])")

# -Wstrict-overflow: http://www.airs.com/blog/archives/120
ifeq ($(GCC42_OR_LATER),1)
  CFLAGS += -Wstrict-overflow
endif

I actually use the same in my code because I don't want to maintain a separate config or Configure.

But you have to use a portable, non-anemic make, like GNU make (gmake), and not Posix's make.

And it does not address the issue of logical AND and OR.

You need to use PRG - Post/Redirect/Get pattern and you have just implemented the P of PRG. You need to Redirect. (Now days you do not need redirection at all. See this)

PRG is a web development design pattern that prevents some duplicate form submissions which means, Submit form (Post Request 1) -> Redirect -> Get (Request 2)

Under the hood

Redirect status code - HTTP 1.0 with HTTP 302 or HTTP 1.1 with HTTP 303

An HTTP response with redirect status code will additionally provide a URL in the location header field. The user agent (e.g. a web browser) is invited by a response with this code to make a second, otherwise identical, request to the new URL specified in the location field.

The redirect status code is to ensure that in this situation, the web user's browser can safely refresh the server response without causing the initial HTTP POST request to be resubmitted.

Double Submit Problem

Post/Redirect/Get Solution

I know my answer is late to the party. But the way i solved is bit different than all the answers.

I had a situation, i need to clone a row in a table except few columns. Those few will have new values. This process should support automatically for future changes to the table. This implies, clone the record without specifying any column names.

My approach is to,

1. Query Sys.Columns to get the full list of columns for the table and include the names of columns to skip in where clause.
2. Convert that in to CSV as column names.
3. Build Select ... Insert into script based on this.

declare @columnsToCopyValues varchar(max), @query varchar(max)
SET @columnsToCopyValues = ''

--Get all the columns execpt Identity columns and Other columns to be excluded. Say IndentityColumn, Column1, Column2
Select @columnsToCopyValues = @columnsToCopyValues + [name] + ', ' from sys.columns c where c.object_id = OBJECT_ID('YourTableName') and name not in ('IndentityColumn','Column1','Column2')
Select @columnsToCopyValues = SUBSTRING(@columnsToCopyValues, 0, LEN(@columnsToCopyValues))
print @columnsToCopyValues
Select @query = CONCAT('insert into YourTableName (',@columnsToCopyValues,', Column1, Column2) select ', @columnsToCopyValues, ',''Value1'',''Value2'',', ' from YourTableName where IndentityColumn =''' , @searchVariable,'''')
print @query
exec (@query)

If you want the content string and this string does not have parameters you can use

    String line = null;
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null){
        System.out.println(line);
    }

I know its already answered, but theres a better solution here use this code :

for ( Field f : context.getFields() ) {
     if ( f.getType() == String.class ) || ( f.getType() == String.class ) ) {
           //DO String To JSON
     }
     /// And so on...
}

This way you can access variables from class without manually typing them..

Faster and better .. Hope this helps.

Cheers. :D

I prefer option two because it clearly shows the list item as the possessor of that nested list. I would always lean towards semantically sound HTML.

I know you are long past getting a solution. So, this is for others that come along to see how other people are solving the same common problem-- like me.

Seems to work on all the browsers I use. http://jsfiddle.net/Q3LW6/. Message shows when textarea loses focus.

Newer, more thorough example: https://jsfiddle.net/BradChesney79/tjj6338a/

Uses and reports .change(), .blur(), .keydown(), .keyup(), .mousedown(), .mouseup(), .click(), mouseleave(), and .setInterval().

This will print all the subdirectories of the current directory:

print [name for name in os.listdir(".") if os.path.isdir(name)]

I'm not sure what you're doing with split("-"), but perhaps this code will help you find a solution?

If you want the full pathnames of the directories, use abspath:

print [os.path.abspath(name) for name in os.listdir(".") if os.path.isdir(name)]

Note that these pieces of code will only get the immediate subdirectories. If you want sub-sub-directories and so on, you should use walk as others have suggested.

I faced with the same error, when i downloaded the Jmeter Source, and it got fixed once i downloaded Jmeter Binary. Please watch this video.

>>> def delete_key(dict, key):
...     del dict[key]
...     return dict
... 
>>> test_dict = {'one': 1, 'two' : 2}
>>> print delete_key(test_dict, 'two')
{'one': 1}
>>>

this doesn't do any error handling, it assumes the key is in the dict, you might want to check that first and raise if its not

string str1, str2, str3;

cout << "These are the strings: " << endl;
cout << "str1: \"the dog jumped over the fence\"" << endl;
cout << "str2: \"the\"" << endl;
cout << "str3: \"that\"" << endl << endl;

From this, I see that you have not initialized str1, str2, or str3 to contain the values that you are printing. I might suggest doing so first:

string str1 = "the dog jumped over the fence", 
       str2 = "the",
       str3 = "that";

cout << "These are the strings: " << endl;
cout << "str1: \"" << str1 << "\"" << endl;
cout << "str2: \"" << str2 << "\"" << endl;
cout << "str3: \"" << str3 << "\"" << endl << endl;

You need a root node

I got the same problem and here my solution:

1. go to service.msc and find mysql service. set it as start manually.
2. go to task manager - processes tab and find mysqld. stop it
3. go to task manager - services tab find mysql service and stop it

It is because display:inline-block takes into account white-space in the html. If you remove the white-space between the div's it works as expected. Live Example: http://jsfiddle.net/XCDsu/4/

<div id="col1">content</div><div id="col2">content</div>

This error might also occur if you define the __construct method more than once.

All these answers around here, as well as the answers in this question, suggest that loading absolute URLs, like "/foo/bar.properties" treated the same by class.getResourceAsStream(String) and class.getClassLoader().getResourceAsStream(String). This is NOT the case, at least not in my Tomcat configuration/version (currently 7.0.40).

MyClass.class.getResourceAsStream("/foo/bar.properties"); // works!  
MyClass.class.getClassLoader().getResourceAsStream("/foo/bar.properties"); // does NOT work!

Sorry, I have absolutely no satisfying explanation, but I guess that tomcat does dirty tricks and his black magic with the classloaders and cause the difference. I always used class.getResourceAsStream(String) in the past and haven't had any problems.

PS: I also posted this over here

I am using this.

s = s.replaceAll("\\W", ""); 

It replace all special characters from string.

Here

\w : A word character, short for [a-zA-Z_0-9]

\W : A non-word character

Just thinking you might be feel unfamiliar of the sequence From->Where->Select, as in sql script, it is like Select->From->Where.

But you may not know that inside Sql Engine, it is also parse in the sequence of 'From->Where->Select', To validate it, you can try a simple script

select id as i from table where i=3

and it will not work, the reason is engine will parse Where before Select, so it won't know alias i in the where. To make this work, you can try

select * from (select id as i from table) as t where i = 3

The below code illustrates how using a generator returns a result before completion, unlike the traditional non generator approach that returns a complete array after full iteration. With the generator below, the values are returned when ready, no need to wait for an array to be completely filled:

<?php 

function sleepiterate($length) {
    for ($i=0; $i < $length; $i++) {
        sleep(2);
        yield $i;
    }
}

foreach (sleepiterate(5) as $i) {
    echo $i, PHP_EOL;
}

When doing;

a_file = open('E:\Python Win7-64-AMD 3.3\Test', encoding='utf-8')

...you're trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.

Your other example though;

a_file = open('E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')

should work well if you just have the permission on a.txt. You may want to use a raw (r-prefixed) string though, to make sure your path does not contain any escape characters like \n that will be translated to special characters.

a_file = open(r'E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')

No. If such a feature existed it would be listed in this syntax illustration. (Although it's possible there is an undocumented SQL feature, or maybe there is some package that I'm not aware of.)

I think most of the answers have completely ignored UINavigationViewController, so I handled this use case with following implementation.

+ (UIViewController *)topMostController {
    UIViewController * topController = [UIApplication sharedApplication].keyWindow.rootViewController;
    while (topController.presentedViewController || [topController isMemberOfClass:[UINavigationController class]]) {
        if([topController isMemberOfClass:[UINavigationController class]]) {
            topController = [topController childViewControllers].lastObject;
        } else {
            topController = topController.presentedViewController;
        }
    }

    return topController;
}

You can do that nowadays with FormData and URLSearchParams without the need to loop over anything.

const formData = new FormData(form);
const searchParams = new URLSearchParams(formData);
const queryString = searchParams.toString();

Older browsers will need a polyfill, though.

I am using the SVG using D3.js and i had the same issue.

I used this code for removing the previous svg but the linear gradient inside SVG were not coming in IE

$("#container_div_id").html("");

then I wrote the below code to resolve the issue

$('container_div_id g').remove();
$('#container_div_id path').remove();

here i am removing the previous g and path inside the SVG, replacing with the new one.

Keeping my linear gradient inside SVG tags in the static content and then I called the above code, This works in IE

Generally speaking, float is a relative positioning statement, since it specifies the position of the element relative to its parent container (floating to the right or left). This means it's incompatible with the position:absolute property, because position:absolute is an absolute positioning statement. You can either float an element and allow the browser to position it relative to its parent container, or you can specify an absolute position and force the element to appear in a certain position regardless of its parent. If you want an absolutely-positioned element to appear on the right side of the screen, you can use position: absolute; right: 0;, but this will cause the element to always appear on the right edge of the screen regardless of how wide its parent div is (so it won't be "at the right of its parent div").

Being DialogFragment a wrapper for the Dialog class, you should set a theme to your base Dialog to get the animation you want:

public class CustomDialogFragment extends DialogFragment implements OnEditorActionListener
{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) 
    {
        return super.onCreateView(inflater, container, savedInstanceState);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) 
    {
        // Set a theme on the dialog builder constructor!
        AlertDialog.Builder builder = 
            new AlertDialog.Builder( getActivity(), R.style.MyCustomTheme );

        builder  
        .setTitle( "Your title" )
        .setMessage( "Your message" )
        .setPositiveButton( "OK" , new DialogInterface.OnClickListener() 
            {      
              @Override
              public void onClick(DialogInterface dialog, int which) {
              dismiss();                  
            }
        });
        return builder.create();
    }
}

Then you just need to define the theme that will include your desired animation. In styles.xml add your custom theme:

<style name="MyCustomTheme" parent="@android:style/Theme.Panel">
    <item name="android:windowAnimationStyle">@style/MyAnimation.Window</item>
</style>

<style name="MyAnimation.Window" parent="@android:style/Animation.Activity"> 
    <item name="android:windowEnterAnimation">@anim/anim_in</item>
    <item name="android:windowExitAnimation">@anim/anim_out</item>
</style>    

Now add the animation files in the res/anim folder:

( the android:pivotY is the key )

anim_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
        android:interpolator="@android:anim/linear_interpolator"
        android:fromXScale="0.0"
        android:toXScale="1.0"
        android:fromYScale="0.0"
        android:toYScale="1.0"
        android:fillAfter="false"
        android:startOffset="200"
        android:duration="200" 
        android:pivotX = "50%"
        android:pivotY = "-90%"
    />
    <translate
        android:fromYDelta="50%"
        android:toYDelta="0"
        android:startOffset="200"
        android:duration="200"
    />
</set>

anim_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
        android:interpolator="@android:anim/linear_interpolator"
        android:fromXScale="1.0"
        android:toXScale="0.0"
        android:fromYScale="1.0"
        android:toYScale="0.0"
        android:fillAfter="false"
        android:duration="200" 
        android:pivotX = "50%"        
        android:pivotY = "-90%"        
    />
    <translate
        android:fromYDelta="0"
        android:toYDelta="50%"
        android:duration="200"
    />
</set>

Finally, the tricky thing here is to get your animation grow from the center of each row. I suppose the row is filling the screen horizontally so, on one hand the android:pivotX value will be static. On the other hand, you can't modify the android:pivotY value programmatically.

What I suggest is, you define several animations each of which having a different percentage value on the android:pivotY attribute (and several themes referencing those animations). Then, when the user taps the row, calculate the Y position in percentage of the row on the screen. Knowing the position in percentage, assign a theme to your dialog that has the appropriate android:pivotY value.

It is not a perfect solution but could do the trick for you. If you don't like the result, then I would suggest forgetting the DialogFragment and animating a simple View growing from the exact center of the row.

Good luck!

This code will work it out definitely

function closing() {
var answer = confirm("Do you wnat to close this window ?");
    if (answer){
        netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserWrite');
        window.close();
    }
    else{
        stop;
    }
}

You also can do like this:

default: &default
  adapter: mysql2
  encoding: utf8
  username: root
  password:
  host: 127.0.0.1
  port: 3306

development:
  <<: *default
  database: development_db_name

test:
  <<: *default
  database: test_db_name

production:
  <<: *default
  database: production_db_name

UPDATE: since Angular 1.6

You can no longer use the JSON_CALLBACK string as a placeholder for specifying where the callback parameter value should go

You must now define the callback like so:

$http.jsonp('some/trusted/url', {jsonpCallbackParam: 'callback'})

Change/access/declare param via $http.defaults.jsonpCallbackParam, defaults to callback

Note: You must also make sure your URL is added to the trusted/whitelist:

$sceDelegateProvider.resourceUrlWhitelist

or explicitly trusted via:

$sce.trustAsResourceUrl(url)

success/error were deprecated.

The $http legacy promise methods success and error have been deprecated and will be removed in v1.6.0. Use the standard then method instead. If $httpProvider.useLegacyPromiseExtensions is set to false then these methods will throw $http/legacy error.

USE:

var url = "http://public-api.wordpress.com/rest/v1/sites/wtmpeachtest.wordpress.com/posts"
var trustedUrl = $sce.trustAsResourceUrl(url);

$http.jsonp(trustedUrl, {jsonpCallbackParam: 'callback'})
    .then(function(data){
        console.log(data.found);
    });

Previous Answer: Angular 1.5.x and before

All you should have to do is change callback=jsonp_callback to callback=JSON_CALLBACK like so:

var url = "http://public-api.wordpress.com/rest/v1/sites/wtmpeachtest.wordpress.com/posts?callback=JSON_CALLBACK";

And then your .success function should fire like you have it if the return was successful.

Doing it this way keeps you from having to dirty up the global space. This is documented in the AngularJS documentation here.

Updated Matt Ball's fiddle to use this method: http://jsfiddle.net/subhaze/a4Rc2/114/

Full example:

var url = "http://public-api.wordpress.com/rest/v1/sites/wtmpeachtest.wordpress.com/posts?callback=JSON_CALLBACK";

$http.jsonp(url)
    .success(function(data){
        console.log(data.found);
    });

Non-regex solution

I ran some benchmarks, and this solution won hugely:¹

str.slice(str.indexOf(delim) + delim.length)

// as function
function gobbleStart(str, delim) {
    return str.slice(str.indexOf(delim) + delim.length);
}

// as polyfill
String.prototype.gobbleStart = function(delim) {
    return this.slice(this.indexOf(delim) + delim.length);
};

Performance comparison with other solutions

The only close contender was the same line of code, except using substr instead of slice.

Other solutions I tried involving split or RegExps took a big performance hit and were about 2 orders of magnitude slower. Using join on the results of split, of course, adds an additional performance penalty.

Why are they slower? Any time a new object or array has to be created, JS has to request a chunk of memory from the OS. This process is very slow.

Here are some general guidelines, in case you are chasing benchmarks:

• New dynamic memory allocations for objects {} or arrays [] (like the one that split creates) will cost a lot in performance.
• RegExp searches are more complicated and therefore slower than string searches.
• If you already have an array, destructuring arrays is about as fast as explicitly indexing them, and looks awesome.

Removing beyond the first instance

Here's a solution that will slice up to and including the nth instance. It's not quite as fast, but on the OP's question, gobble(element, '_', 1) is still >2x faster than a RegExp or split solution and can do more:

/*
`gobble`, given a positive, non-zero `limit`, deletes
characters from the beginning of `haystack` until `needle` has
been encountered and deleted `limit` times or no more instances
of `needle` exist; then it returns what remains. If `limit` is
zero or negative, delete from the beginning only until `-(limit)`
occurrences or less of `needle` remain.
*/
function gobble(haystack, needle, limit = 0) {
  let remain = limit;
  if (limit <= 0) { // set remain to count of delim - num to leave
    let i = 0;
    while (i < haystack.length) {
      const found = haystack.indexOf(needle, i);
      if (found === -1) {
        break;
      }
      remain++;
      i = found + needle.length;
    }
  }

  let i = 0;
  while (remain > 0) {
    const found = haystack.indexOf(needle, i);
    if (found === -1) {
      break;
    }
    remain--;
    i = found + needle.length;
  }
  return haystack.slice(i);
}

With the above definition, gobble('path/to/file.txt', '/') would give the name of the file, and gobble('prefix_category_item', '_', 1) would remove the prefix like the first solution in this answer.

1. Tests were run in Chrome 70.0.3538.110 on macOSX 10.14.

I work with a bunch of UI frameworks. Many of them have a built-in class you can use to visually hide things.

Bootstrap

<input type="submit" class="sr-only" tabindex="-1">

Angular Material

<input type="submit" class="cdk-visually-hidden" tabindex="-1">

Brilliant minds who created these frameworks have defined these styles as follows:

.sr-only {
    position: absolute;
    width: 1px;
    height: 1px;
    padding: 0;
    overflow: hidden;
    clip: rect(0, 0, 0, 0);
    white-space: nowrap;
    border: 0;
}

.cdk-visually-hidden {
    border: 0;
    clip: rect(0 0 0 0);
    height: 1px;
    margin: -1px;
    overflow: hidden;
    padding: 0;
    position: absolute;
    width: 1px;
    outline: 0;
    -webkit-appearance: none;
    -moz-appearance: none;
}

Most of the posts that I found will timeout after a second iteration. Particularly if you are looping through a bunch if images as I have been. So to improve the suggestions above here is the entire method:

public System.Drawing.Image DownloadImage(string imageUrl)
    {
        System.Drawing.Image image = null;

        try
        {
            System.Net.HttpWebRequest webRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(imageUrl);
            webRequest.AllowWriteStreamBuffering = true;
            webRequest.Timeout = 30000;
            webRequest.ServicePoint.ConnectionLeaseTimeout = 5000;
            webRequest.ServicePoint.MaxIdleTime = 5000;

            using (System.Net.WebResponse webResponse = webRequest.GetResponse())
            {

                using (System.IO.Stream stream = webResponse.GetResponseStream())
                {
                    image = System.Drawing.Image.FromStream(stream);
                }
            }

            webRequest.ServicePoint.CloseConnectionGroup(webRequest.ConnectionGroupName);
            webRequest = null; 
        }
        catch (Exception ex)
        {
            throw new Exception(ex.Message, ex);

        }


        return image;
    }

msg * Hello world

works for me..

Thanx @krd, I am using your error catch process, but had to update the print and except statements. I am using Python 2.7.6 on Linux Mint 17.2.

Also, it was unclear where the output string was coming from. My update:

import subprocess

# Output returned in error handler
try:
    print("Ping stdout output on success:\n" + 
           subprocess.check_output(["ping", "-c", "2", "-w", "2", "1.1.1.1"]))
except subprocess.CalledProcessError as e:
    print("Ping stdout output on error:\n" + e.output)

# Output returned normally
try:

except subprocess.CalledProcessError as e:
    print("Ping stdout output on error:\n" + e.output)

Add an object to an array

class App extends React.Component {
  state = {
  value: ""
  };

items = [
  {
    id: 0,
    title: "first item"
  },
  {
    id: 1,
    title: "second item"
  },
  {
    id: 2,
    title: "third item"
  }
];

handleChange = e => {
  this.setState({
    value: e.target.value
  });
};

handleAddItem = () => {
  if (this.state.value === "") return;
  const item = new Object();
  item.id = this.items.length;
  item.title = this.state.value;
  this.items.push(item);
  this.setState({
    value: ""
  });

  console.log(this.items);
};

render() {
  const items = this.items.map(item => <p>{item.title}</p>);
  return (
    <>
      <label>
        <input
          value={this.state.value}
          type="text"
          onChange={this.handleChange}

        <button onClick={this.handleAddItem}>Add item</button>
      </label>

  );
}
}

ReactDOM.render(<App />, document.getElementById("root"));

Note that since May 2013 ("Repository redirects are here!"), you can rename your GitHub repo without breaking any links:

We're happy to announce that starting today, we'll automatically redirect all requests for previous repository locations to their new home in these circumstances. There's nothing special you have to do. Just rename away and we'll take care of the rest.

As a special bonus, we'll also be servicing all Git clone, fetch, and push requests from previous repository locations.

That means you don't even have to git remote set-url (change the url of your remote GitHub repo) on your local cloned repo!
Although Gabriel notes in the comments that the official GitHub help page strongly recommends that you do so:

to reduce confusion, we strongly recommend updating any existing local clones to point to the new repository URL. You can do this by using git remote on the command line:

git remote set-url origin new_url

Beware though:

GitHub Pages sites are not automatically redirected when their repositories are renamed at this time.
Renaming a Pages repository will continue to break any existing links to content hosted on the github.io domain or custom domains.

Plus, the user still owns the namespace: if he/she creates a new repo using the old name of the renamed repo, that redirection (for said renamed repo) will stop working.

Simply Enter Esc and type m it will convert to text cell.

import socket
from threading import *

serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = "192.168.1.3"
port = 8000
print (host)
print (port)
serversocket.bind((host, port))

class client(Thread):
    def __init__(self, socket, address):
        Thread.__init__(self)
        self.sock = socket
        self.addr = address
        self.start()

    def run(self):
        while 1:
            print('Client sent:', self.sock.recv(1024).decode())
            self.sock.send(b'Oi you sent something to me')

serversocket.listen(5)
print ('server started and listening')
while 1:
    clientsocket, address = serversocket.accept()
    client(clientsocket, address)

This is a very VERY simple design for how you could solve it. First of all, you need to either accept the client (server side) before going into your while 1 loop because in every loop you accept a new client, or you do as i describe, you toss the client into a separate thread which you handle on his own from now on.

Be aware that if your string number contains more than 15 significant digits float(s) will round it.In those cases it is better to use Decimal

Here is an explanation and some code samples: https://docs.python.org/3/library/sys.html#sys.float_info

This command worked for me

find . -mtime -1 -print

In addition to @KenM's answer, another important distinction is that, when loading in a saved object, you can assign the contents of an Rds file. Not so for Rda

> x <- 1:5
> save(x, file="x.Rda")
> saveRDS(x, file="x.Rds")
> rm(x)

## ASSIGN USING readRDS
> new_x1 <- readRDS("x.Rds")
> new_x1
[1] 1 2 3 4 5

## 'ASSIGN' USING load -- note the result
> new_x2 <- load("x.Rda")
loading in to  <environment: R_GlobalEnv> 
> new_x2
[1] "x"
# NOTE: `load()` simply returns the name of the objects loaded. Not the values. 
> x
[1] 1 2 3 4 5

To create multiple sub-folders

mkdir -p parentfolder/{subfolder1,subfolder2,subfolder3}

You should be iterating over the tuple and checking if the key is in the dict not the other way around, if you don't check if the key exists and it is not in the dict you are going to get a key error:

print({k:d[k] for k in l if k in d})

Some timings:

 {k:d[k] for k in set(d).intersection(l)}

In [22]: %%timeit                        
l = xrange(100000)
{k:d[k] for k in l}
   ....: 
100 loops, best of 3: 11.5 ms per loop

In [23]: %%timeit                        
l = xrange(100000)
{k:d[k] for k in set(d).intersection(l)}
   ....: 
10 loops, best of 3: 20.4 ms per loop

In [24]: %%timeit                        
l = xrange(100000)
l = set(l)                              
{key: d[key] for key in d.viewkeys() & l}
   ....: 
10 loops, best of 3: 24.7 ms per

In [25]: %%timeit                        

l = xrange(100000)
{k:d[k] for k in l if k in d}
   ....: 
100 loops, best of 3: 17.9 ms per loop

I don't see how {k:d[k] for k in l} is not readable or elegant and if all elements are in d then it is pretty efficient.

simple one:

[[@"first" stringByAppendingString:@"second"] stringByAppendingString:@"third"];

if you have many STRINGS to Concatenate, you should use NSMutableString for better performance

It's called dependency injection via constructor injection: class A gets the dependency as an argument to its constructor and saves the reference to dependent class as a private variable.

There's an interesting introduction on wikipedia.

For const-correctness I'd write:

using T = int;

class A
{
public:
  A(const T &thing) : m_thing(thing) {}
  // ...

private:
   const T &m_thing;
};

but a problem with this class is that it accepts references to temporary objects:

T t;
A a1{t};    // this is ok, but...

A a2{T()};  // ... this is BAD.

It's better to add (requires C++11 at least):

class A
{
public:
  A(const T &thing) : m_thing(thing) {}
  A(const T &&) = delete;  // prevents rvalue binding
  // ...

private:
  const T &m_thing;
};

Anyway if you change the constructor:

class A
{
public:
  A(const T *thing) : m_thing(*thing) { assert(thing); }
  // ...

private:
   const T &m_thing;
};

Also, since the constructor takes a pointer, it's clearer to users of A that they need to pay attention to the lifetime of the object they pass.

Somewhat related topics are:

• Should I prefer pointers or references in member data?
• Using reference as class members for dependencies
• GotW #88
• Forbid rvalue binding via constructor to member const reference

It's actually easy and straight forward.

just navigate to your .m2 folder.

.m2/repository/org/apache/maven

inside this maven folder, you will see a folder called Archetypes... delete this folder and the problem is solved.

but if you don't feel like deleting the whole folder, you can navigate into the archetype folder and delete all the archetype you want there. The reason why it keeps failing is because, the archetype you are trying to create is trying to tell you that she already exists in that folder, hence move away...

summarily, deleting the archetype folder in the .m2 folder is the easiest solution.

In case if you need a matrix with predefined numbers you can use the following code:

def matrix(rows, cols, start=0):
    return [[c + start + r * cols for c in range(cols)] for r in range(rows)]


assert matrix(2, 3, 1) == [[1, 2, 3], [4, 5, 6]]

To safe, you should add: mContext.getResources().getString(R.string.your_string);

mContext can be: context in onAttach() of Fragment or this of Activity.

As a general rule, you should never completly remove the outline or :focus style.

https://a11yproject.com/posts/never-remove-css-outlines

...using outline: none without proper fallbacks makes your site significantly less accessible to any keyboard only user, not only those with reduced vision. Make sure to always give your interactive elements a visible indication of focus.

You could use this:

data[:1] = ['hello']

Maybe you're looking for something like this:

$(document).click(function(e)
   {
       if($(e.srcElement).attr('id')=='id')
       {
           alert('click on #id');
       }
       else
       {
            alert('click on something else'); 
       }
   });

jsfiddle

You may retrieve a pointer to the clicked element using event.srcElement .

So all you have to do is to check the id-attribute of the clicked element.

<ScrollView 
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/scroll" 
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

      <LinearLayout 
            android:id="@+id/container"
            android:orientation="vertical" 
            android:layout_width="match_parent"

$ids = sprintf("'%s'", implode("','", $ids ) );

One thing I find that is often missing from these is an ability to look up row locks. At least on the larger databases I have worked on, row locks are not shown in pg_locks (if they were, pg_locks would be much, much larger and there isn't a real data type to show the locked row in that view properly).

I don't know that there is a simple solution to this but usually what I do is look at the table where the lock is waiting and search for rows where the xmax is less than the transaction id present there. That usually gives me a place to start, but it is a bit hands-on and not automation friendly.

Note that shows you uncommitted writes on rows on those tables. Once committed, the rows are not visible in the current snapshot. But for large tables, that is a pain.

I'm sorry but i can't comment your answers already due my reputation!...so, if you wanna modify the structure of your object, you must do like Thane Plummer says, but a little trick if you do not care where to put the item: it will be inserted on first position if you don't specify the number for the insertion.

This is wonderful if you want to pass a Json object for instance to a mongoDB function call and insert a new key inside the conditions you receive. In this case I gonna insert a item myUid with some info from a variable inside my code:

// From backend or anywhere_x000D_
let myUid = { _id: 'userid128344'};_x000D_
// .._x000D_
// .._x000D_
_x000D_
  let myrequest = { _id: '5d8c94a9f629620ea54ccaea'};_x000D_
  const answer = findWithUid( myrequest).exec();_x000D_
_x000D_
// .._x000D_
// .._x000D_
_x000D_
function findWithUid( conditions) {_x000D_
  const cond_uid = Object.assign({uid: myUid}, conditions);_x000D_
  // the object cond_uid now is:_x000D_
  // {uid: 'userid128344', _id: '5d8c94a9f629620ea54ccaea'}_x000D_
  // so you can pass the new object Json completly with the new key_x000D_
  return myModel.find(cond_uid).exec();_x000D_
}

I met the same problem even using -ldl.

Besides this option, source files need to be placed before libraries, see undefined reference to `dlopen'.

If you have configured navigation property 1-n I would recommend you to use:

var query = db.Categories                                  // source
   .SelectMany(c=>c.CategoryMaps,                          // join
      (c, cm) => new { Category = c, CategoryMaps = cm })  // project result
   .Select(x => x.Category);                               // select result

Much more clearer to me and looks better with multiple nested joins.

I want to leave this here because I struggled with this when compiling for Android in Windows with the Android SDK.

CMake distinguishes between TARGET and HOST platform.

My TARGET was Android so the variables like CMAKE_SYSTEM_NAME had the value "Android" and the variable WIN32 from the other answer here was not defined. But I wanted to know if my HOST system was Windows because I needed to do a few things differently when compiling on either Windows or Linux or IOs. To do that I used CMAKE_HOST_SYSTEM_NAME which I found is barely known or mentioned anywhere because for most people TARGEt and HOST are the same or they don't care.

Hope this helps someone somewhere...

Given that all the dataframes have the same columns, you can simply concat them:

import pandas as pd
df = pd.concat(list_of_dataframes)

"What is a “static” function in C?"

Let's start at the beginning.

It´s all based upon a thing called "linkage":

"An identifier declared in different scopes or in the same scope more than once can be made to refer to the same object or function by a process called linkage. 29)There are three kinds of linkage: external, internal, and none."

Source: C18, 6.2.2/1

"In the set of translation units and libraries that constitutes an entire program, each declaration of a particular identifier with external linkage denotes the same object or function. Within one translation unit, each declaration of an identifier with internal linkage denotes the same object or function. Each declaration of an identifier with no linkage denotes a unique entity."

Source: C18, 6.2.2/2

If a function is defined without a storage-class specifier, the function has external linkage by default:

"If the declaration of an identifier for a function has no storage-class specifier, its linkage is determined exactly as if it were declared with the storage-class specifier extern."

Source: C18, 6.2.2/5

That means that - if your program is contained of several translation units/source files (.c or .cpp) - the function is visible in all translation units/source files your program has.

This can be a problem in some cases. What if you want to use f.e. two different function (definitions), but with the same function name in two different contexts (actually the file-context).

In C and C++, the static storage-class qualifier applied to a function at file scope (not a static member function of a class in C++ or a function within another block) now comes to help and signifies that the respective function is only visible inside of the translation unit/source file it was defined in and not in the other TLUs/files.

"If the declaration of a file scope identifier for an object or a function contains the storage-class specifier static, the identifier has internal linkage. 30)"

30. A function declaration can contain the storage-class specifier static only if it is at file scope; see 6.7.1.

Source: C18, 6.2.2/3

Thus, A static function only makes sense, iff:

1. Your program is contained of several translation units/source files (.c or .cpp).

and

2. You want to limit the scope of a function to the file, in which the specific function is defined.

If not both of these requirements match, you don't need to wrap your head around about qualifying a function as static.

Side Notes:

• As already mentioned, A static function has absolutely no difference at all between C and C++, as this is a feature C++ inherited from C.

It does not matter that in the C++ community, there is a heartbreaking debate about the depreciation of qualifying functions as static in comparison to the use of unnamed namespaces instead, first initialized by a misplaced paragraph in the C++03 standard, declaring the use of static functions as deprecated which soon was revised by the committee itself and removed in C++11.

This was subject to various SO questions:

Unnamed/anonymous namespaces vs. static functions

Superiority of unnamed namespace over static?

Why an unnamed namespace is a "superior" alternative to static?

Deprecation of the static keyword... no more?

In fact, it is not deprecated per C++ standard yet. Thus, the use of static functions is still legit. Even if unnamed namespaces have advantages, the discussion about using or not using static functions in C++ is subject to one´s one mind (opinion-based) and with that not suitable for this website.

You can get it with:

var html = new System.Net.WebClient().DownloadString(siteUrl)

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();  
GraphicsDevice[] screens = ge.getScreenDevices();       
Rectangle allScreenBounds = new Rectangle();  
for (GraphicsDevice screen : screens) {  
       Rectangle screenBounds = screen.getDefaultConfiguration().getBounds();        
       allScreenBounds.width += screenBounds.width;  
       allScreenBounds.height = Math.max(allScreenBounds.height, screenBounds.height);
       allScreenBounds.x=Math.min(allScreenBounds.x, screenBounds.x);
       allScreenBounds.y=Math.min(allScreenBounds.y, screenBounds.y);
      } 
Robot robot = new Robot();
BufferedImage bufferedImage = robot.createScreenCapture(allScreenBounds);
File file = new File("C:\\Users\\Joe\\Desktop\\scr.png");
if(!file.exists())
    file.createNewFile();
FileOutputStream fos = new FileOutputStream(file);
ImageIO.write( bufferedImage, "png", fos );

bufferedImage will contain a full screenshot, this was tested with three monitors

you can simply do:

In[17]:df['combined']=df['bar'].astype(str)+'_'+df['foo']+'_'+df['new']

In[17]:df
Out[18]: 
   bar foo     new    combined
0    1   a   apple   1_a_apple
1    2   b  banana  2_b_banana
2    3   c    pear    3_c_pear

The Boost.String library has a lot of algorithms for doing case-insenstive comparisons and so on.

You could implement your own, but why bother when it's already been done?

In Bash 5 there's a new variable:

echo $EPOCHSECONDS

Or if you want higher precision (in microseconds):

echo $EPOCHREALTIME

in dir bootstrap\autoload.php

require __DIR__.'/../vendor/autoload.php';
require __DIR__.'/../app/Helpers/function.php'; //add

add this file

app\Helpers\function.php

If you want to run the tsc command from the integrated terminal with the TypeScript module installed locally, you can add the following to your .vscode\settings.json file.

{
  "terminal.integrated.env.windows": { "PATH": "${workspaceFolder}\\node_modules\\.bin;${env:PATH}" }
}

This will prepend the locally installed node module's binary/executable directory (where tsc.cmd is located) to the $env.PATH variable.

Bundling is all about compressing several JavaScript or stylesheets files without any formatting (also referred as minified) into a single file for saving bandwith and number of requests to load a page.

As example you could create your own bundle:

bundles.Add(New ScriptBundle("~/bundles/mybundle").Include(
            "~/Resources/Core/Javascripts/jquery-1.7.1.min.js",
            "~/Resources/Core/Javascripts/jquery-ui-1.8.16.min.js",
            "~/Resources/Core/Javascripts/jquery.validate.min.js",
            "~/Resources/Core/Javascripts/jquery.validate.unobtrusive.min.js",
            "~/Resources/Core/Javascripts/jquery.unobtrusive-ajax.min.js",
            "~/Resources/Core/Javascripts/jquery-ui-timepicker-addon.js"))

And render it like this:

@Scripts.Render("~/bundles/mybundle")

One more advantage of @Scripts.Render("~/bundles/mybundle") over the native <script src="~/bundles/mybundle" /> is that @Scripts.Render() will respect the web.config debug setting:

  <system.web>
    <compilation debug="true|false" />

If debug="true" then it will instead render individual script tags for each source script, without any minification.

For stylesheets you will have to use a StyleBundle and @Styles.Render().

Instead of loading each script or style with a single request (with script or link tags), all files are compressed into a single JavaScript or stylesheet file and loaded together.

I'm on Gson 2.8.6 and discovered this bug today.

My approach allows all our existing clients (mobile/web/etc) to continue functioning as they were, but adds some handling for those using 24h formats and allows millis too, for good measure.

Gson rawGson = new Gson();
SimpleDateFormat fmt = new SimpleDateFormat("MMM d, yyyy HH:mm:ss")
private class DateDeserializer implements JsonDeserializer<Date> {
    @Override
    public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context)
            throws JsonParseException {
        try {
            return new rawGson.fromJson(json, Date.class);
        } catch (JsonSyntaxException e) {}
        String timeString = json.getAsString();
        log.warning("Standard date deserialization didn't work:" + timeString);
        try {
            return fmt.parse(timeString);
        } catch (ParseException e) {}
        log.warning("Parsing as json 24 didn't work:" + timeString);
        return new Date(json.getAsLong());
    }
}

Gson gson = new GsonBuilder()
    .registerTypeAdapter(Date.class, new DateDeserializer())
    .create();

I kept serialization the same as all clients understand the standard json date format.

Ordinarily, I don't think it's good practice to use try/catch blocks, but this should be a fairly rare case.

Add this line with your EditText tag.

android:digits="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"

Your EditText tag should look like:

<EditText
        android:id="@+id/editText1"
        android:digits="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

Try with this script, maybe will be useful:

SELECT CAST('TRUE' as bit) -- RETURN 1
SELECT CAST('FALSE' as bit) --RETURN 0

Anyway I always would use a value of 1 or 0 (not TRUE or FALSE). Following your example, the update script would be:

Update Table Set BitField=CAST('TRUE' as bit) Where ID=1

Just in case you were wondering how to rename columns during aggregation, here's how for

pandas >= 0.25: Named Aggregation

df.groupby('Company Name')['Amount'].agg(MySum='sum', MyCount='count')

Or,

df.groupby('Company Name').agg(MySum=('Amount', 'sum'), MyCount=('Amount', 'count'))

                       MySum  MyCount
Company Name                       
Vifor Pharma UK Ltd  4207.93        5

It is better if you don't kill a thread. A way could be to introduce a "try" block into the thread's cycle and to throw an exception when you want to stop the thread (for example a break/return/... that stops your for/while/...). I've used this on my app and it works...

The absolutely best way: Just let your activity implement View.OnClickListener, and write your onClick method like this:

public void onClick(View v) {
    final int id = v.getId();
    switch (id) {
    case R.id.button1:
        // your code for button1 here
        break;
    case R.id.button2:
        // your code for button2 here
        break;
    // even more buttons here
    }
}

Then, in your XML layout file, you can set the click listeners directly using the attribute android:onClick:

<Button
    android:id="@+id/button1"
    android:onClick="onClick"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button 1" />

That is the most cleanest way of how to do it. I use it in all of mine projects today, as well.

As of 2020 language management become easy! All you have to do is:

1. Call to Activity.applyOverrideConfiguration
2. And call to Locale.setDefault

You must call those from the activity constructor since you can call to applyOverrideConfiguration only once, and the system calls it pretty early.

And watch out from app-bundles, Google will split your APK by language resources automatically when using app-bundles. Check out the new API and the workaround here.

I created a helper class to help you with it. In my implementation G.app is the application context. Also, I need to access resources from the app context so I use the Res class for it, this one is optional, but I provide its code as well.

Usage

public BaseActivity(){
    LanguageUtility.init(this);
}

public void changeLanguage(Local local){
    // you must recreat your activity after you call this
    LanguageUtillity.setDefaultLanguage(local, this);
}

Source code

public class LanguageUtility {

    private static Configuration configuration;

Because of the infinite superiority of Python over Java, Python has not one, but two toString operations.

One is __str__, the other is __repr__

__str__ will return a human readable string. __repr__ will return an internal representation.

__repr__ can be invoked on an object by calling repr(obj) or by using backticks `obj`.

When printing lists as well as other container classes, the contained elements will be printed using __repr__.

As previously answered here, since PHP 5.2.0 you can use the DateTime class and specify the UTC timezone with an instance of DateTimeZone.

The DateTime __construct() documentation suggests passing "now" as the first parameter when creating a DateTime instance and specifying a timezone to get the current time.

$date_utc = new \DateTime("now", new \DateTimeZone("UTC"));

echo $date_utc->format(\DateTime::RFC850); # Saturday, 18-Apr-15 03:23:46 UTC

From Resetting SQL Server Identity Columns:

Retrieving the identity for the table Employees:

DBCC checkident ('Employees')

Repairing the identity seed (if for some reason the database is inserting duplicate identities):

DBCC checkident ('Employees', reseed)

Changing the identity seed for the table Employees to 1000:

DBCC checkident ('Employees', reseed, 1000)

The next row inserted will begin at 1001.

@DawidDrozd's answer above is excellent.

I would add one point. Recent versions of the Clang compiler complain about requiring a "bridging cast" if attempting to use his code.

This seems reasonable: using a trampoline creates a potential bug: since Objective-C classes are reference counted, if we pass their address around as a void *, we risk having a hanging pointer if the class is garbage collected up while the callback is still active.

Solution 1) Cocoa provides CFBridgingRetain and CFBridgingRelease macro functions which presumably add and subtract one from the reference count of the Objective-C object. We should therefore be careful with multiple callbacks, to release the same number of times as we retain.

// C++ Module
#include <functional>

void cppFnRequiringCallback(std::function<void(void)> callback) {
        callback();
}

//Objective-C Module
#import "CppFnRequiringCallback.h"

@interface MyObj : NSObject
- (void) callCppFunction;
- (void) myCallbackFn;
@end

void cppTrampoline(const void *caller) {
        id callerObjC = CFBridgingRelease(caller);
        [callerObjC myCallbackFn];
}

@implementation MyObj
- (void) callCppFunction {
        auto callback = [self]() {
                const void *caller = CFBridgingRetain(self);
                cppTrampoline(caller);
        };
        cppFnRequiringCallback(callback);
}

- (void) myCallbackFn {
    NSLog(@"Received callback.");
}
@end

Solution 2) The alternative is to use the equivalent of a weak reference (ie. no change to the retain count), without any additional safety.

The Objective-C language provides the __bridge cast qualifier to do this (CFBridgingRetain and CFBridgingRelease seem to be thin Cocoa wrappers over the Objective-C language constructs __bridge_retained and release respectively, but Cocoa does not appear to have an equivalent for __bridge).

The required changes are:

void cppTrampoline(void *caller) {
        id callerObjC = (__bridge id)caller;
        [callerObjC myCallbackFn];
}

- (void) callCppFunction {
        auto callback = [self]() {
                void *caller = (__bridge void *)self;
                cppTrampoline(caller);
        };
        cppFunctionRequiringCallback(callback);
}

If you really need to use a secure foreach interface to iterate an object and make it reusable and clean with a npm module, then use this, https://www.npmjs.com/package/foreach-object

Ex:

import each from 'foreach-object';
   
const object = {
   firstName: 'Arosha',
   lastName: 'Sum',
   country: 'Australia'
};
   
each(object, (value, key, object) => {
   console.log(key + ': ' + value);
});
   
// Console log output will be:
//      firstName: Arosha
//      lastName: Sum
//      country: Australia

You have already staged the changes (presumably by running git add), so in order to get their diff, you need to run:

git diff --cached

(A plain git diff will only show unstaged changes.)

For example:

Working syntax for multiple optional params:

<Route path="/section/(page)?/:page?/(sort)?/:sort?" component={Section} />

Now, url can be:

1. /section
2. /section/page/1
3. /section/page/1/sort/asc

The trick is that the DOM Element.children attribute is not an array but an array-like collection which has length and can be indexed like an array, but it is not an array:

var children = tableFields.children;
for (var i = 0; i < children.length; i++) {
  var tableChild = children[i];
  // Do stuff
}

Incidentally, in general it is a better practice to iterate over an array using a basic for-loop instead of a for-in-loop.

The schema for passing the value in as a string. The regex will validate a string of at least one digit, possibly followed by a period and exactly two digits:

{
    "type": "string",
    "pattern": "^[0-9]+(\\.[0-9]{2})?$"
}

The schema below is equivalent, except that it also allows empty strings:

{
    "type": "string",
    "pattern": "^$|^[0-9]+(\\.[0-9]{2})?$"
}

A structure allocates the total size of all elements in it.

A union only allocates as much memory as its largest member requires.

You can also use OpenCV's inbuilt functions cv2.hconcat and cv2.vconcat which like their names suggest are used to join images horizontally and vertically respectively.

import cv2

img1 = cv2.imread('opencv/lena.jpg')
img2 = cv2.imread('opencv/baboon.jpg')

v_img = cv2.vconcat([img1, img2])
h_img = cv2.hconcat([img1, img2])

cv2.imshow('Horizontal', h_img)
cv2.imshow('Vertical', v_img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Horizontal Concatenation

Vertical Concatenation

Here is an updated solution for Java8, using lambdas and streams:

System.out.println(list.stream()
                       .map(Object::toString)
                       .collect(Collectors.joining("\n")));

Or, without joining the list into one large string:

list.stream().forEach(System.out::println);

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

One way for me to understand wildcards is to think that the wildcard isn't specifying the type of the possible objects that given generic reference can "have", but the type of other generic references that it is is compatible with (this may sound confusing...) As such, the first answer is very misleading in it's wording.

In other words, List<? extends Serializable> means you can assign that reference to other Lists where the type is some unknown type which is or a subclass of Serializable. DO NOT think of it in terms of A SINGLE LIST being able to hold subclasses of Serializable (because that is incorrect semantics and leads to a misunderstanding of Generics).

This is very good question but not as wanting as question. There is difference between 'self' and 'cls' used method though analogically they are at same place

def moon(self, moon_name):
    self.MName = moon_name

#but here cls method its use is different 

@classmethod
def moon(cls, moon_name):
    instance = cls()
    instance.MName = moon_name

Now you can see both are moon function but one can be used inside class while other function name moon can be used for any class.

For practical programming approach :

While designing circle class we use area method as cls instead of self because we don't want area to be limited to particular class of circle only .

The problem is you're telling Gson you have an object of your type. You don't. You have an array of objects of your type. You can't just try and cast the result like that and expect it to magically work ;)

The User guide for Gson Explains how to deal with this:

https://github.com/google/gson/blob/master/UserGuide.md

This will work:

ChannelSearchEnum[] enums = gson.fromJson(yourJson, ChannelSearchEnum[].class);

But this is better:

Type collectionType = new TypeToken<Collection<ChannelSearchEnum>>(){}.getType();
Collection<ChannelSearchEnum> enums = gson.fromJson(yourJson, collectionType);

Some basic differences can be written in short:

MVC:

Traditional MVC is where there is a

1. Model: Acts as the model for data
2. View : Deals with the view to the user which can be the UI
3. Controller: Controls the interaction between Model and View, where view calls the controller to update model. View can call multiple controllers if needed.

MVP:

Similar to traditional MVC but Controller is replaced by Presenter. But the Presenter, unlike Controller is responsible for changing the view as well. The view usually does not call the presenter.

MVVM

The difference here is the presence of View Model. It is kind of an implementation of Observer Design Pattern, where changes in the model are represented in the view as well, by the VM. Eg: If a slider is changed, not only the model is updated but the data which may be a text, that is displayed in the view is updated as well. So there is a two-way data binding.

Something like the following example. Note I'm in Eastern Australia (UTC + 10 hours at the moment).

>>> import datetime
>>> dtnow = datetime.datetime.now();dtutcnow = datetime.datetime.utcnow()
>>> dtnow
datetime.datetime(2010, 8, 4, 9, 33, 9, 890000)
>>> dtutcnow
datetime.datetime(2010, 8, 3, 23, 33, 9, 890000)
>>> delta = dtnow - dtutcnow
>>> delta
datetime.timedelta(0, 36000)
>>> hh,mm = divmod((delta.days * 24*60*60 + delta.seconds + 30) // 60, 60)
>>> hh,mm
(10, 0)
>>> "%s%+02d:%02d" % (dtnow.isoformat(), hh, mm)
'2010-08-04T09:33:09.890000+10:00'
>>>

You can also specify the exact values for each gr

0 2,10,12,14,16,18,20 * * *

It stands for 2h00, 10h00, 12h00 and so on, till 20h00.

From the above answer, we have:

The comma, ",", means "and". If you are confused by the above line, remember that spaces are the field separators, not commas.

And from (Wikipedia page):

*    *    *    *    *  command to be executed
-    -    -    -    -
¦    ¦    ¦    ¦    ¦
¦    ¦    ¦    ¦    ¦
¦    ¦    ¦    ¦    +----- day of week (0 - 7) (0 or 7 are Sunday, or use names)
¦    ¦    ¦    +---------- month (1 - 12)
¦    ¦    +--------------- day of month (1 - 31)
¦    +-------------------- hour (0 - 23)
+------------------------- min (0 - 59)

Hope it helps :)

EDIT:

• don't miss the 1st 0 (zero) and the following space: it means "the minute zero", you can also set it to 15 (the 15th minute) or expressions like */15 (every minute divisible by 15, i.e. 0,15,30)

Starting an Activity is not the right approach for this behavior. Instead have your BroadcastReceiver use an intent to start a Service which can continue to run as long as possible. (See http://developer.android.com/reference/android/app/Service.html#ProcessLifecycle)

Francis Shanahan,

1. Why do you call partial postback as "nonsense"? This is the core feature of Ajax and has been utilized very well in Atlas framework and wonderful third party controls like Telerik

2. I agree to your point regarding the viewstate. But if developers are careful to disable viewstate, this can greatly reduce the size of the HTML which is rendered thus the page becomes light weight.

3. Only HTML Server controls are renamed in ASP.NET Web Form model and not pure html controls. Whatever it may be, why are you so worried if the renaming is done? I know you want to deal with lot of javascript events on the client side but if you design your web pages smartly, you can definitely get all the id's you want

4. Even ASP.NET Web Forms meets XHTML Standards and I don't see any bloating. This is not a justification of why we need an MVC pattern

5. Again, why are you bothered with AXD Javascript? Why does it hurts you? This is not a valid justification again

So far, i am a fan of developing applications using classic ASP.NET Web forms. For eg: If you want to bind a dropdownlist or a gridview, you need a maximum of 30 minutes and not more than 20 lines of code (minimal of course). But in case of MVC, talk to the developers how pain it is.

The biggest downside of MVC is we are going back to the days of ASP. Remember the spaghetti code of mixing up Server code and HTML??? Oh my god, try to read an MVC aspx page mixed with javascript, HTML, JQuery, CSS, Server tags and what not....Any body can answer this question?

I answered a similar question (see Javascript callback when IFRAME is finished loading?). You can obtain control over the iframe load event with the following code:

function callIframe(url, callback) {
    $(document.body).append('<IFRAME id="myId" ...>');
    $('iframe#myId').attr('src', url);

    $('iframe#myId').load(function() {
        callback(this);
    });
}

In dealing with iframes I found good enough to use load event instead of document ready event.

I didn't want to reinstall everything because I have so many SDK versions installed and my development environment is set up just right. Getting it set up again takes way too long.

What worked for me was deleting, then re-creating the Android Virtual Device, being certain to put in a value for SD Card Size (I used 200 MiB).

Additional information:

while the above does fix the problem temporarily, it is recurring. I just tried my application within Android Studio and saw this in the output log which I did not notice before in Eclipse:

"/Applications/Android Studio.app/sdk/tools/emulator" -avd AVD_for_Nexus_S_by_Google -netspeed full -netdelay none

WARNING: Data partition already in use. Changes will not persist!
WARNING: SD Card image already in use: /Users/[user]/.android/avd/AVD_for_Nexus_S_by_Google.avd/sdcard.img
ko:Snapshot storage already in use: /Users/[user]/.android/avd/AVD_for_Nexus_S_by_Google.avd/snapshots.img

I suspect that changes to the log are not saving to the SD Card, so when LogCat tries to access the logs, they aren't there, causing the error message. The act of deleting the AVD and re-creating it removes the files, and the next launch is a fresh launch, allowing LogCat to access the virtual SD Card.

Its Simple. Create a function and pass a parameter. In that function copy the first index into a new variable. Then Create a for loop and loop through the array. Inside a loop create an while loop with a condition checking whether the new created variable is equal to all the elements in the loop. if its equal return true after the for loop completes else return false inside the while loop.

function isUniform(arra){
    var k=arra[0];
    for (var i = 0; i < arra.length; i++) {
        while(k!==arra[i]){
            return false;
        }
    }
    return true;
}

This answer helped to me download image from server to client side.

If you are calling this function through a submit button. This may be the reason why the browser does not redirect. It will run the code in the function and then submit the page instead of redirect. In this case change the type tag of your button.

public String humanReadable(long size) {
    long limit = 10 * 1024;
    long limit2 = limit * 2 - 1;
    String negative = "";
    if(size < 0) {
        negative = "-";
        size = Math.abs(size);
    }

    if(size < limit) {
        return String.format("%s%s bytes", negative, size);
    } else {
        size = Math.round((double) size / 1024);
        if (size < limit2) {
            return String.format("%s%s kB", negative, size);
        } else {
            size = Math.round((double)size / 1024);
            if (size < limit2) {
                return String.format("%s%s MB", negative, size);
            } else {
                size = Math.round((double)size / 1024);
                if (size < limit2) {
                    return String.format("%s%s GB", negative, size);
                } else {
                    size = Math.round((double)size / 1024);
                        return String.format("%s%s TB", negative, size);
                }
            }
        }
    }
}

Similar to @nayun oh answer above, but for older versions of Spring, use this code:

SpringApplication application = new SpringApplication(DemoApplication.class);
application.setApplicationContextClass(AnnotationConfigApplicationContext.class);
application.run(args);

Residuum did provide a correct answer to how you should get shell exec to find your script, but in regards to security, there are a couple of points.

I would imagine you don't want your shell script to be in your web root, as it would be visible to anyone with web access to your server.

I would recommend moving the shell script to outside of the webroot

    <?php
      $tempFolder = '/tmp';
      $webRootFolder = '/var/www';
      $scriptName = 'myscript.sh';
      $moveCommand = "mv $webRootFolder/$scriptName $tempFolder/$scriptName";
      $output = shell_exec($moveCommand);
    ?>

In regards to the:

i added www-data ALL=(ALL) NOPASSWD:ALL to /etc/sudoers works

You can modify this to only cover the specific commands in your script which require sudo. Otherwise, if none of the commands in your sh script require sudo to execute, you don't need to do this at all anyway.

Try running the script as the apache user (use the su command to switch to the apache user) and if you are not prompted for sudo or given permission denied, etc, it'll be fine.

ie:

sudo su apache (or www-data)
cd /var/www
sh ./myscript

Also... what brought me here was that I wanted to run a multi line shell script using commands that are dynamically generated. I wanted all of my commands to run in the same shell, which won't happen using multiple calls to shell_exec(). The answer to that one is to do it like Jenkins - create your dynamically generated multi line of commands, put it in a variable, save it to a file in a temp folder, execute that file (using shell_exec in() php as Jenkins is Java), then do whatever you want with the output, and delete the temp file

... voila

if type(varA) == str or type(varB) == str:

from EDX - online course MITx: 6.00.1x Introduction to Computer Science and Programming Using Python

Well, the error is pretty clear, no? You are trying to connect to your SQL Server with user "xyz/ASPNET" - that's the account your ASP.NET app is running under.

This account is not allowed to connect to SQL Server - either create a login on SQL Server for that account, or then specify another valid SQL Server account in your connection string.

Can you show us your connection string (by updating your original question)?

UPDATE: Ok, you're using integrated Windows authentication --> you need to create a SQL Server login for "xyz\ASPNET" on your SQL Server - or change your connection string to something like:

connectionString="Server=.\SQLExpress;Database=IFItest;User ID=xyz;pwd=top$secret"

If you have a user "xyz" with a password of "top$secret" in your database.

I had the same problem of the html data tag not updating when i was using jquery But changing the code that does the actual work from jquery to javascript worked.

Try using this when the button is clicked: (Note that the main code is Javascripts setAttribute() function.)

function increment(q) {

    //increment current num by adding with 1
    q = q+1;

    //change data attribute using JS setAttribute function
    div.setAttribute('data-num',q);

    //refresh data-num value (get data-num value again using JS getAttribute function)
    num = parseInt(div.getAttribute('data-num'));

    //show values
    console.log("(After Increment) Current Num: "+num);

}

//get variables, set as global vars
var div = document.getElementById('foo');
var num = parseInt(div.getAttribute('data-num'));

//increment values using click
$("#changeData").on('click',function(){

    //pass current data-num as parameter
    increment(num);

});
