Still not cool enough to comment, but regarding @vladislav's comment the original article was fairly old. Here is an update document regarding DTU's, which would help answer the OP's question.

https://docs.microsoft.com/en-us/azure/sql-database/sql-database-what-is-a-dtu

for empty all input tags such as input,select,textatea etc. run this code

$('#message').val('').change();

The code below fleshes out the answer above, displaying the screen size as a Toast.

//Determine screen size
if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_LARGE) {
    Toast.makeText(this, "Large screen", Toast.LENGTH_LONG).show();
}
else if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_NORMAL) {
    Toast.makeText(this, "Normal sized screen", Toast.LENGTH_LONG).show();
}
else if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_SMALL) {
    Toast.makeText(this, "Small sized screen", Toast.LENGTH_LONG).show();
}
else {
    Toast.makeText(this, "Screen size is neither large, normal or small", Toast.LENGTH_LONG).show();
}

This code below displays the screen density as a Toast.

//Determine density
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int density = metrics.densityDpi;

if (density == DisplayMetrics.DENSITY_HIGH) {
    Toast.makeText(this, "DENSITY_HIGH... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show();
}
else if (density == DisplayMetrics.DENSITY_MEDIUM) {
    Toast.makeText(this, "DENSITY_MEDIUM... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show();
}
else if (density == DisplayMetrics.DENSITY_LOW) {
    Toast.makeText(this, "DENSITY_LOW... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show();
}
else {
    Toast.makeText(this, "Density is neither HIGH, MEDIUM OR LOW.  Density is " + String.valueOf(density), Toast.LENGTH_LONG).show();
}

You can use unionByName to make this:

df = df_1.unionByName(df_2)

unionByName is available since Spark 2.3.0.

You can also run this command.

mysql --help | grep cnf

If you won't go with regex:

"ABCDEFGHIJKLMNOP".toLowerCase().contains("gHi".toLowerCase())

As also noted by John Szakmeister and VasiliNovikov, the shortest command to get the full diff from master's perspective on your branch is:

git diff master...

This uses your local copy of master.

To compare a specific file use:

git diff master... filepath

Output example:

L = ['L','O','L']
makeitastring = ''.join(map(str, L))

You can use datetime module to help here. Also, as a side note, a simple date subtraction should work as below:

import datetime as dt
import numpy as np
import pandas as pd

Hope that helps.

the command posted by Milad and Sandy did not work for me with mstsc. i had to add TERMSRV to the /generic switch. i found this information here: https://gist.github.com/jdforsythe/48a022ee22c8ec912b7e

cmdkey /generic:TERMSRV/<server> /user:<username> /pass:<password>

i could then use mstsc /v:<server> without getting prompted for the login.

In addition to other answers need to add that parameters not only helps prevent sql injection but can improve performance of queries. Sql server caching parameterized query plans and reuse them on repeated queries execution. If you not parameterized your query then sql server would compile new plan on each query(with some exclusion) execution if text of query would differ.

More information about query plan caching

You can convert varchars to floats, and you can do it in the manner you have expressed. Your varchar must not be a numeric value. There must be something else in it. You can use IsNumeric to test it. See this:

declare @thing varchar(100)

select @thing = '122.332'

--This returns 1 since it is numeric.
select isnumeric(@thing)

--This converts just fine.
select convert(float,@thing)

select @thing = '122.332.'

--This returns 0 since it is not numeric.
select isnumeric(@thing)

--This convert throws.
select convert(float,@thing)

I was having the same problem too and it was driving me crazy:

Windows7 64 bit, MinGW, Eclipse, CDT

Permission denied errors, executable disappearing, ld.exe errors. It would work once, but never again. Statements like: "cannot open output file ***.exe: Permission denied"

Check your ANTIVIRUS Software. Once I turned off my Antivirus software in workspace then cleaned the workspace and started the project over again I never had the problem again.

Canvas would be a great way to do this, as @pst said above. Check out this answer for a good example:

getPixel from HTML Canvas?

Some code that would serve you specifically as well:

var imgd = context.getImageData(x, y, width, height);
var pix = imgd.data;

for (var i = 0, n = pix.length; i < n; i += 4) {
  console.log pix[i+3]
}

This will go row by row, so you'd need to convert that into an x,y and either convert the for loop to a direct check or run a conditional inside.

Reading your question again, it looks like you want to be able to get the point that the person clicks on. This can be done pretty easily with jquery's click event. Just run the above code inside a click handler as such:

$('el').click(function(e){
   console.log(e.clientX, e.clientY)
}

Those should grab your x and y values.

Depends what you mean by "post data". You can use the HTML target="" attribute on a <form /> tag, so it could be as simple as:

<form action="do_stuff.aspx" method="post" target="my_iframe">
  <input type="submit" value="Do Stuff!">
</form>

<!-- when the form is submitted, the server response will appear in this iframe -->
<iframe name="my_iframe" src="not_submitted_yet.aspx"></iframe>

If that's not it, or you're after something more complex, please edit your question to include more detail.

There is a known bug with Internet Explorer that only occurs when you're dynamically creating your iframes, etc. using Javascript (there's a work-around here), but if you're using ordinary HTML markup, you're fine. The target attribute and frame names isn't some clever ninja hack; although it was deprecated (and therefore won't validate) in HTML 4 Strict or XHTML 1 Strict, it's been part of HTML since 3.2, it's formally part of HTML5, and it works in just about every browser since Netscape 3.

I have verified this behaviour as working with XHTML 1 Strict, XHTML 1 Transitional, HTML 4 Strict and in "quirks mode" with no DOCTYPE specified, and it works in all cases using Internet Explorer 7.0.5730.13. My test case consist of two files, using classic ASP on IIS 6; they're reproduced here in full so you can verify this behaviour for yourself.

I would be very interested to hear of any browser that doesn't run these examples correctly.

Answer on an old question, this new post is posted on April the 4th 2013

To complete the answer of @misza, here a advanced method to check if cookies are enabled without page reloading. The problem with @misza is that it not always work when the php ini setting session.use_cookies is not true. Also the solution does not check if a session is already started.

I made this function and test it many times with in different situations and does the job very well.

    function suGetClientCookiesEnabled() // Test if browser has cookies enabled
    {
      // Avoid overhead, if already tested, return it
      if( defined( 'SU_CLIENT_COOKIES_ENABLED' ))
       { return SU_CLIENT_COOKIES_ENABLED; }

      $bIni = ini_get( 'session.use_cookies' ); 
      ini_set( 'session.use_cookies', 1 ); 

      $a = session_id();
      $bWasStarted = ( is_string( $a ) && strlen( $a ));
      if( !$bWasStarted )
      {
        @session_start();
        $a = session_id();
      }

   // Make a copy of current session data
  $aSesDat = (isset( $_SESSION ))?$_SESSION:array();
   // Now we destroy the session and we lost the data but not the session id 
   // when cookies are enabled. We restore the data later. 
  @session_destroy(); 
   // Restart it
  @session_start();

   // Restore copy
  $_SESSION = $aSesDat;

   // If no cookies are enabled, the session differs from first session start
  $b = session_id();
  if( !$bWasStarted )
   { // If not was started, write data to the session container to avoid data loss
     @session_write_close(); 
   }

   // When no cookies are enabled, $a and $b are not the same
  $b = ($a === $b);
  define( 'SU_CLIENT_COOKIES_ENABLED', $b );

  if( !$bIni )
   { @ini_set( 'session.use_cookies', 0 ); }

  //echo $b?'1':'0';
  return $b;
    }

Usage:

if( suGetClientCookiesEnabled())
 { echo 'Cookies are enabled!'; }
else { echo 'Cookies are NOT enabled!'; }

Important note: The function temporarily modify the ini setting of PHP when it not has the correct setting and restore it when it was not enabled. This is only to test if cookies are enabled. It can get go wrong when you start a session and the php ini setting session.use_cookies has an incorrect value. To be sure that the session is working correctly, check and/or set it before start a session, for example:

   if( suGetClientCookiesEnabled())
     { 
       echo 'Cookies are enabled!'; 
       ini_set( 'session.use_cookies', 1 ); 
       echo 'Starting session';
       @start_session(); 

     }
    else { echo 'Cookies are NOT enabled!'; }

This is an old post but...

You can reference the working directory (the folder the .html file is located in) with ./, and the directory above that with ../

Example directory structure:

/html/public/
- index.html
- script2.js
- js/
   - script.js

To load script.js from inside index.html:

<script type="text/javascript" src="./js/script.js">

This goes to the current working directory (location of index.html) and then to the js folder, and then finds the script.

You could also specify ../ to go one directory above the working directory, to load things from there. But that is unusual.

I had a similar problem with a less complicated formula:

= If (x > A & x <= B) 

and found that I could Remove the AND and join the two comparisons with +

  = (x > A1) + (x <= B1)        [without all the spaces]

Hope this helps others with less complex comparisons.

I created a simple jQuery plugin which does just this. It uses the ':tabbable' selector of jQuery UI to find the next 'tabbable' element and selects it.

Example usage:

// Simulate tab key when element is clicked 
$('.myElement').bind('click', function(event){
    $.tabNext();
    return false;
});

Try this:

Integer startIn = null;

try {
  startIn = Integer.valueOf(startField.getText());
} catch (NumberFormatException e) {
  .
  .
  .
}

if (startIn == null) {
  // Prompt for value...
}

Update 2019

The :has() pseudo-selector is propsed in the CSS Selectors 4 spec, and will address this use case once implemented.

To use it, we will write something like:

.foo > .bar:has(> .baz) { /* style here */ }

In a structure like:

<div class="foo">
  <div class="bar">
    <div class="baz">Baz!</div>
  </div>
</div>

This CSS will target the .bar div - because it both has a parent .foo and from its position in the DOM, > .baz resolves to a valid element target.

Original Answer (left for historical purposes) - this portion is no longer accurate

For completeness, I wanted to point out that in the Selectors 4 specification (currently in proposal), this will become possible. Specifically, we will gain Subject Selectors, which will be used in the following format:

!div > span { /* style here */

The ! before the div selector indicates that it is the element to be styled, rather than the span. Unfortunately, no modern browsers (as of the time of this posting) have implemented this as part of their CSS support. There is, however, support via a JavaScript library called Sel, if you want to go down the path of exploration further.

Turn off your firewall for port 80 from any address. Turn off 443 if you need https (SSL) access. Open the configuration file (http.conf) and find the lines that say:

Allow from 127.0.0.1

Change them to read

Allow from all

Restart the wampserver. It will now work. Enjoy!!

If you want it to be used on many platforms, you could as commented use defines like:

#if defined(_MSC_VER) || defined(WIN32)  || defined(_WIN32) || defined(__WIN32__) \
                        || defined(WIN64)    || defined(_WIN64) || defined(__WIN64__) 

        errno_t err = fopen_s(&stream,name, "w");

#endif

#if defined(unix)        || defined(__unix)      || defined(__unix__) \
                        || defined(linux)       || defined(__linux)     || defined(__linux__) \
                        || defined(sun)         || defined(__sun) \
                        || defined(BSD)         || defined(__OpenBSD__) || defined(__NetBSD__) \
                        || defined(__FreeBSD__) || defined __DragonFly__ \
                        || defined(sgi)         || defined(__sgi) \
                        || defined(__MACOSX__)  || defined(__APPLE__) \
                        || defined(__CYGWIN__) 

        stream = fopen(name, "w");

#endif

just give rowId and type of data that is going to be update in ContentValues.

public void updateStatus(String id , int status){

SQLiteDatabase db = this.getWritableDatabase();

ContentValues data = new ContentValues();

data.put("status", status);

db.update(TableName, data, "columnName" + " = "+id , null);

}

Many answers (including the original of this one) don't address the letter- and number-count requirements of the OP. Below are two solutions: general (no min letters/numbers), and with rules.

General:

I believe this is better general solution than the above, because:

• it's more secure than accepted/highest-voted answer, and also more versatile, because it supports any char set in a case-sensitive manner
• it's more concise than other answers (for general solution, 3 lines max; can be one-liner)
• it uses only native Javascript- no installation or other libs required

Note that

• for this to work on IE, the Array.fill() prototype must be polyfilled
• if available, better to use window.crypto.getRandomValues() instead of Math.random() (thanks @BenjaminH for pointing out)

Three-liner:

var pwdChars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
var pwdLen = 10;
var randPassword = Array(pwdLen).fill(pwdChars).map(function(x) { return x[Math.floor(Math.random() * x.length)] }).join('');

Or, as one-liner:

var randPassword = Array(10).fill("0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz").map(function(x) { return x[Math.floor(Math.random() * x.length)] }).join('');

With Letter / Number Rules

Now, a variation on the above. This will generate three random strings from the given charsets (letter, number, either) and then scramble the result.

Please note the below uses sort() for illustrative purposes only. For production use, replace the below sort() function with a shuffle function such as Durstenfeld.

First, as a function:

function randPassword(letters, numbers, either) {
  var chars = [
   "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz", // letters
   "0123456789", // numbers
   "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" // either
  ];

  return [letters, numbers, either].map(function(len, i) {
    return Array(len).fill(chars[i]).map(function(x) {
      return x[Math.floor(Math.random() * x.length)];
    }).join('');
  }).concat().join('').split('').sort(function(){
    return 0.5-Math.random();
  }).join('')
}

// invoke like so: randPassword(5,3,2);

Same thing, as a 2-liner (admittedly, very long and ugly lines-- and won't be a 1-liner if you use a proper shuffle function. Not recommended but sometimes it's fun anyway) :

var chars = ["ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz","0123456789", "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"];
var randPwd = [5,3,2].map(function(len, i) { return Array(len).fill(chars[i]).map(function(x) { return x[Math.floor(Math.random() * x.length)] }).join('') }).concat().join('').split('').sort(function(){return 0.5-Math.random()}).join('');

According the to Windows Dev Center WIN32_LEAN_AND_MEAN excludes APIs such as Cryptography, DDE, RPC, Shell, and Windows Sockets.

1. You should put the stylesheet links and javascript <script> in the <head>, as that is dictated by the formats. However, some put javascript <script>s at the bottom of the body, so that the page content will load without waiting for the <script>, but this is a tradeoff since script execution will be delayed until other resources have loaded.
2. CSS takes precedence in the order by which they are linked (in reverse): first overridden by second, overridden by third, etc.

The version of EnterpriseLibrary on my machine had other parameters. This was working:

        SqlParameter retval = new SqlParameter("@ReturnValue", System.Data.SqlDbType.Int);
        retval.Direction = System.Data.ParameterDirection.ReturnValue;
        cmd.Parameters.Add(retval);
        db.ExecuteNonQuery(cmd);
        object o = cmd.Parameters["@ReturnValue"].Value;

I met this issue this morning because I used the same executable in DIFFERENT OSes: after compiling my program with gcc -ggdb -Wall test.c -o test in my Mac(10.15.2), I ran gdb with the executable in Ubuntu(16.04) in my VirtualBox.

Fix: recompile with the same command under Ubuntu, then you should be good.

you can use cURL library for posting data: http://www.php.net/curl

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_URL, "http://websiteURL");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "XML=".$xmlcontent."&password=".$password."&etc=etc");
$content=curl_exec($ch);

where postfield contains XML you need to send - you will need to name the postfield the API service (Clickatell I guess) expects

               WHERE user_id = 11 && form_id=9
               ORDER BY updated_at DESC
             ) AS TEMP
    ORDER BY DATE(updated_at) DESC, name DESC

Give it a try.

I have some vague recollections of Oracle databases needing a bit of fiddling when you reboot for the first time after installing the database. However, you haven't given us enough information to work on. To start with:

• What code are you using to connect to the database?
• It's not clear whether the database instance has been started. Can you connect to the database using sqlplus / as sysdba from within the VM?
• What has been written to the listener.log file (in %ORACLE_HOME%\network\log) since the last reboot?

EDIT: I've now been able to come up with a scenario which generates the same error message you got. It looks to me like the database you're attempting to connect to has not been started up. The example I present below uses Oracle XE on Linux, but I don't think this makes a significant difference.

First, let us confirm that the database is shut down:

$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Sat Jul 17 18:16:43 2010

Copyright (c) 1982, 2005, Oracle.  All rights reserved.

Connected to an idle instance.

It's the text Connected to an idle instance that tells us that the database is shut down.

Using sqlplus / as sysdba connects us to the database as SYS without needing a password, but it only works on the same machine as the database itself. In your case, you'd need to run this inside the virtual machine. SYS has permission to start up and shut down the database, and to connect to it when it is shut down, but normal users don't have these permissions.

Now let us disconnect and try reconnecting as a normal user, one that does not have permission to startup/shutdown the database nor connect to it when it is down:

SQL> exit
Disconnected

$ sqlplus -L "user/pw@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID=XE)))"

SP2-0751: Unable to connect to Oracle.  Exiting SQL*Plus

That's the error message you've been getting.

Now, let's start the database up:

$ sqlplus / as sysdba

We're in.

I hadn't seen an ORA-12505 error before because I don't normally connect to an Oracle database by entering the entire connection string on the command line. This is likely to be similar to how you are attempting to connect to the database. Usually, I either connect to a local database, or connect to a remote database by using a TNS name (these are listed in the tnsnames.ora file, in %ORACLE_HOME%\network\admin). In both of these cases you get a different error message if you attempt to connect to a database that has been shut down.

If the above doesn't help you (in particular, if the database has already been started, or you get errors starting up the database), please let us know.

EDIT 2: it seems the problems you were having were indeed because the database hadn't been started. It also appears that your database isn't configured to start up when the service starts. It is possible to get the database to start up when the service is started, and to shut down when the service is stopped. To do this, use the Oracle Administration Assistant for Windows, see here.

For clear frame, first need to destroy all widgets inside the frame,. it will clear frame.

import tkinter as tk
from tkinter import *
root = tk.Tk()

frame = Frame(root)
frame.pack(side="top", expand=True, fill="both")

lab = Label(frame, text="hiiii")
lab.grid(row=0, column=0, padx=10, pady=5)

def clearFrame():
    # destroy all widgets from frame
    for widget in frame.winfo_children():
       widget.destroy()
    
    # this will clear frame and frame will be empty
    # if you want to hide the empty panel then
    frame.pack_forget()

frame.but = Button(frame, text="clear frame", command=clearFrame)
frame.but.grid(row=0, column=1, padx=10, pady=5)

# then whenever you add data in frame then you can show that frame
lab2 = Label(frame, text="hiiii")
lab2.grid(row=1, column=0, padx=10, pady=5)
frame.pack()
root.mainloop()

PEP-8 recommends you indent lines to the opening parentheses if you put anything on the first line, so it should either be indenting to the opening bracket:

urlpatterns = patterns('',
                       url(r'^$', listing, name='investment-listing'))

or not putting any arguments on the starting line, then indenting to a uniform level:

urlpatterns = patterns(
    '',
    url(r'^$', listing, name='investment-listing'),
)

urlpatterns = patterns(
    '', url(r'^$', listing, name='investment-listing'))

I suggest taking a read through PEP-8 - you can skim through a lot of it, and it's pretty easy to understand, unlike some of the more technical PEPs.

A POST request can include a query string, however normally it doesn't - a standard HTML form with a POST action will not normally include a query string for example.

With very large JavaScript applications, programmers are using more encapsulation of code to avoid polluting the global scope. And to make a function available to the onClick action in an HTML element, it has to be in the global scope.

You may have seen JS files that look like this...

(function(){
    ...[some code]
}());

These are Immediately Invoked Function Expressions (IIFEs) and any function declared within them will only exist within their internal scope.

If you declare function doSomething(){} within an IIFE, then make doSomething() an element's onClick action in your HTML page, you'll get an error.

If, on the other hand, you create an eventListener for that element within that IIFE and call doSomething() when the listener detects a click event, you're good because the listener and doSomething() share the IIFE's scope.

For little web apps with a minimal amount of code, it doesn't matter. But if you aspire to write large, maintainable codebases, onclick="" is a habit that you should work to avoid.

just open the bin folder and copy and paste the .dll files to the folder you are working in..it should fix the problem

Use Spring's "PropertyPlaceholderConfigurer" class

A simple example showing property file read dynamically as bean's property

You should override the layoutmanager of your recycleview for this. This way it will only disable scrolling, none of ther other functionalities. You will still be able to handle click or any other touch events. For example:-

Original:

 public class CustomGridLayoutManager extends LinearLayoutManager {
 private boolean isScrollEnabled = true;

 public CustomGridLayoutManager(Context context) {
  super(context);
 }

 public void setScrollEnabled(boolean flag) {
  this.isScrollEnabled = flag;
 }

 @Override
 public boolean canScrollVertically() {
  //Similarly you can customize "canScrollHorizontally()" for managing horizontal scroll
  return isScrollEnabled && super.canScrollVertically();
 }
}

Here using "isScrollEnabled" flag you can enable/disable scrolling functionality of your recycle-view temporarily.

Also:

Simple override your existing implementation to disable scrolling and allow clicking.

 linearLayoutManager = new LinearLayoutManager(context) {
 @Override
 public boolean canScrollVertically() {
  return false;
 }
};

Kotlin:

:LinearLayoutManager(this){ override fun canScrollVertically(): Boolean { return false } }

You could hack your own, not relying on jQuery plugins... though you'd need to keep track externally (in JS) of selected items since the transition would remove the selected state info:

<head>
  <script type='text/javascript' src='http://code.jquery.com/jquery-1.4.4.min.js'></script>
  <script type='text/javascript'>
    $(window).load(function(){
      $('#transactionType').focusin(function(){
        $('#transactionType').attr('multiple', true);
      });
      $('#transactionType').focusout(function(){
        $('#transactionType').attr('multiple', false);
      });
    });>  
  </script>
</head>
<body>
  <select id="transactionType">
    <option value="ALLOC">ALLOC</option>
    <option value="LOAD1">LOAD1</option>
    <option value="LOAD2">LOAD2</option>
  </select>  
</body>

In Rails 3.2.18, :decimal turns into :integer when using SQLServer, but it works fine in SQLite. Switching to :float solved this issue for us.

The lesson learned is "always use homogeneous development and deployment databases!"

My suggestion for google maps api v3 would be(don't think it can be done more effeciently):

gmap : {
    fitBounds: function(bounds, mapId)
    {
        //incoming: bounds - bounds object/array; mapid - map id if it was initialized in global variable before "var maps = [];"
        if (bounds==null) return false;
        maps[mapId].fitBounds(bounds);
    }
}

In the result u will fit all points in bounds in your map window.

Example works perfectly and u freely can check it here www.zemelapis.lt

It seemed that a lot of dependencies were incorrect.

Download the whole POM here

A good place to look for the correct dependencies is the Maven Repository website.

I would suggest 3 things:

1. First try clearing browser's cache
2. Try to assign username & password statically into config.inc.php
3. Once you've done with installation, delete the config.inc.php file under "phpmyadmin" folder

The last one worked for me.

Anwer is here How to dynamically add a style for text-align using jQuery

" the user is the one who select max no and min no ?" What do you mean by this line ?

You can use java function int random = Random.nextInt(n). This returns a random int in range[0, n-1]).

and you can set it in your textview using the setText() method

Finally, after twenty years, there’s a simple solution without the need for a 3rd party library, thanks to Java 9:

InputStream is;
…
byte[] array = is.readAllBytes();

Note also the convenience methods readNBytes(byte[] b, int off, int len) and transferTo(OutputStream) addressing recurring needs.

A functional approach to find existing cookies. It returns an array, so it supports multiple occurrences of the same name. It doesn't support partial key matching, but it's trivial to replace the === in the filter with a regex.

function getCookie(needle) {
    return document.cookie.split(';').map(function(cookiestring) {
        cs = cookiestring.trim().split('=');

        if(cs.length === 2) {
            return {'name' : cs[0], 'value' : cs[1]};
        } else {
            return {'name' : '', 'value' : ''};
        }
    })
    .filter(function(cookieObject) { 
        return (cookieObject.name === needle);
    });
}

Why use SurfaceView and not the classic View class...

One main reason is that SurfaceView can rapidly render the screen.

In simple words a SV is more capable of managing the timing and render animations.

To have a better understanding what is a SurfaceView we must compare it with the View class.

What is the difference... check this simple explanation in the video

https://m.youtube.com/watch?feature=youtu.be&v=eltlqsHSG30

Well with the View we have one major problem....the timing of rendering animations.

Normally the onDraw() is called from the Android run-time system.

So, when Android run-time system calls onDraw() then the application cant control

the timing of display, and this is important for animation. We have a gap of timing

between the application (our game) and the Android run-time system.

The SV it can call the onDraw() by a dedicated Thread.

Thus: the application controls the timing. So we can display the next bitmap image of the animation.

If your modulus is prime (you call it p) then you may simply compute:

y = x**(p-2) mod p  # Pseudocode

Or in Python proper:

y = pow(x, p-2, p)

Here is someone who has implemented some number theory capabilities in Python: http://www.math.umbc.edu/~campbell/Computers/Python/numbthy.html

Here is an example done at the prompt:

m = 1000000007
x = 1234567
y = pow(x,m-2,m)
y
989145189L
x*y
1221166008548163L
x*y % m
1L

A very simple solution to that is to open the file:

YOURPROJECT.xcodeproj/project.pbxproj

And find for this variable:

PRODUCT_BUNDLE_IDENTIFIER

You'll see something like that:

PRODUCT_BUNDLE_IDENTIFIER = com.YOUR_APP_NAME.SOMETHING;

So, the name on the right is your Bundle Identifier. In my case it works perfectly.

Check if the text you're trying to append to the node is not escaped like this:

var prop = {
    match: {
        description: '<h1>Hi there!</h1>'
    }
};

Instead of this:

var prop = {
    match: {
        description: '<h1>Hi there!</h1>'
    }
};

if is escaped you should convert it from your server-side.

The node is text because is escaped

The node is a dom node because isn't escaped

Looks like divs will not go outside of their body's width. Even within another div.

I threw this up to test (without a doctype though) and it does not work as thought.

.slideContainer {_x000D_
    overflow-x: scroll;_x000D_
}_x000D_
.slide {_x000D_
    float: left;_x000D_
}

<div class="slideContainer">_x000D_
    <div class="slide" style="background: #f00">Some content Some content Some content Some content Some content Some content</div>_x000D_
    <div class="slide" style="background: #ff0">More content More content More content More content More content More content</div>_x000D_
    <div class="slide" style="background: #f0f">Even More content! Even More content! Even More content!</div>_x000D_
</div>

What i am thinking is that the inner div's could be loaded through an iFrame, since that is another page and its content could be very wide.

The API Guide has it all wrong (really Google?). With Maps API v2 you do not need to enable a layer to show yourself, there is a simple call to the GoogleMaps instance you created with your map.

Google Documentation

The actual documentation that Google provides gives you your answer. You just need to

If you are using Kotlin

// map is a GoogleMap object
map.isMyLocationEnabled = true

If you are using Java

// map is a GoogleMap object
map.setMyLocationEnabled(true);

and watch the magic happen.

Just make sure that you have location permission and requested it at runtime on API Level 23 (M) or above

http://en.wikibooks.org/wiki/LaTeX/Formatting

use \alltt environment instead. Then set size using the same commands as outside verbatim environment.

Just install python newest version's installer it will automatically detect your python version and will say upgrade python and starts upgrading

If you know the full path to the file you can just do something similar to this. However if you question directly relates to relative paths, that I am unfamiliar with and would have to research and test.

path = 'C:\\Users\\Username\\Path\\To\\File'

with open(path, 'w') as f:
    f.write(data)

Edit:

Here is a way to do it relatively instead of absolute. Not sure if this works on windows, you will have to test it.

import os

cur_path = os.path.dirname(__file__)

new_path = os.path.relpath('..\\subfldr1\\testfile.txt', cur_path)
with open(new_path, 'w') as f:
    f.write(data)

Edit 2: One quick note about __file__, this will not work in the interactive interpreter due it being ran interactively and not from an actual file.

I think this is what you want, I already tested this code and works

The tools used are: (all these tools can be downloaded as Nuget packages)

http://fluentassertions.codeplex.com/

http://autofixture.codeplex.com/

http://code.google.com/p/moq/

https://nuget.org/packages/AutoFixture.AutoMoq

var fixture = new Fixture().Customize(new AutoMoqCustomization());
var myInterface = fixture.Freeze<Mock<IFileConnection>>();

var sut = fixture.CreateAnonymous<Transfer>();

myInterface.Setup(x => x.Get(It.IsAny<string>(), It.IsAny<string>()))
        .Throws<System.IO.IOException>();

sut.Invoking(x => 
        x.TransferFiles(
            myInterface.Object, 
            It.IsAny<string>(), 
            It.IsAny<string>()
        ))
        .ShouldThrow<System.IO.IOException>();

Edited:

Let me explain:

When you write a test, you must know exactly what you want to test, this is called: "subject under test (SUT)", if my understanding is correctly, in this case your SUT is: Transfer

So with this in mind, you should not mock your SUT, if you substitute your SUT, then you wouldn't be actually testing the real code

When your SUT has external dependencies (very common) then you need to substitute them in order to test in isolation your SUT. When I say substitute I'm referring to use a mock, dummy, mock, etc depending on your needs

In this case your external dependency is IFileConnection so you need to create mock for this dependency and configure it to throw the exception, then just call your SUT real method and assert your method handles the exception as expected

• var fixture = new Fixture().Customize(new AutoMoqCustomization());: This linie initializes a new Fixture object (Autofixture library), this object is used to create SUT's without having to explicitly have to worry about the constructor parameters, since they are created automatically or mocked, in this case using Moq

• var myInterface = fixture.Freeze<Mock<IFileConnection>>();: This freezes the IFileConnection dependency. Freeze means that Autofixture will use always this dependency when asked, like a singleton for simplicity. But the interesting part is that we are creating a Mock of this dependency, you can use all the Moq methods, since this is a simple Moq object

• var sut = fixture.CreateAnonymous<Transfer>();: Here AutoFixture is creating the SUT for us

• myInterface.Setup(x => x.Get(It.IsAny<string>(), It.IsAny<string>())).Throws<System.IO.IOException>(); Here you are configuring the dependency to throw an exception whenever the Get method is called, the rest of the methods from this interface are not being configured, therefore if you try to access them you will get an unexpected exception

• sut.Invoking(x => x.TransferFiles(myInterface.Object, It.IsAny<string>(), It.IsAny<string>())).ShouldThrow<System.IO.IOException>();: And finally, the time to test your SUT, this line uses the FluenAssertions library, and it just calls the TransferFiles real method from the SUT and as parameters it receives the mocked IFileConnection so whenever you call the IFileConnection.Get in the normal flow of your SUT TransferFiles method, the mocked object will be invoking throwing the configured exception and this is the time to assert that your SUT is handling correctly the exception, in this case, I am just assuring that the exception was thrown by using the ShouldThrow<System.IO.IOException>() (from the FluentAssertions library)

This problem can also come up when you don't have your constructor immediately call super.

So this will work:

  public Employee(String name, String number, Date date)
  {
    super(....)
  }

But this won't:

  public Employee(String name, String number, Date date)
  {
    // an example of *any* code running before you call super.
    if (number < 5)
    {
       number++;
    }

    super(....)
  }

The reason the 2nd example fails is because java is trying to implicitely call

super(name,number,date)

as the first line in your constructor.... So java doesn't see that you've got a call to super going on later in the constructor. It essentially tries to do this:

  public Employee(String name, String number, Date date)
  {
    super(name, number, date);

    if (number < 5)
    {
       number++;
    }

    super(....)
  }

So the solution is pretty easy... Just don't put code before your super call ;-) If you need to initialize something before the call to super, do it in another constructor, and then call the old constructor... Like in this example pulled from this StackOverflow post:

public class Foo
{
    private int x;

    public Foo()
    {
        this(1);
    }

    public Foo(int x)
    {
        this.x = x;
    }
}

It is a very common issue and the solution is very easy... Just update the SDK in SDK manager(see full instructions below)

1. Open Android Studio and go to your SDK Manager(File>Settings>SDK Manager)
2. Check for (-) icon in front of any package and click on it.
3. Click OK to start updating the SDK.

Thanks for asking that question :)

This one is working for me.

func stringByAddingPercentEncodingForFormData(plusForSpace: Bool=false) -> String? {

    let unreserved = "*-._"
    let allowed = NSMutableCharacterSet.alphanumericCharacterSet()
    allowed.addCharactersInString(unreserved)

    if plusForSpace {
        allowed.addCharactersInString(" ")
    }

    var encoded = stringByAddingPercentEncodingWithAllowedCharacters(allowed)

    if plusForSpace {
        encoded = encoded?.stringByReplacingOccurrencesOfString(" ", withString: "+")
    }
    return encoded
}

I found above function from this link: http://useyourloaf.com/blog/how-to-percent-encode-a-url-string/.

Try this:

1. Put both elements in a container DIV.
2. Give that container the property overflow:auto
3. Float both elements to the left using float:left
4. Give the H1 a width so that it doesn't take up the full width of it's parent container.

The type of expression

" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'"

is std::string. However function system has declaration

int system(const char *s);

that is it accepts an argumnet of type const char *

There is no conversion operator that would convert implicitly an object of type std::string to object of type const char *.

Nevertheless class std::string has two functions that do this conversion explicitly. They are c_str() and data() (the last can be used only with compiler that supports C++11)

So you can write

string name = "john";

system( (" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'").c_str() );

There is no need to use an intermediate variable for the expression.

I created a base class for creating string-valued enums in .NET. It is just one C# file that you can copy & paste into your projects, or install via NuGet package named StringEnum.

Usage:

///<completionlist cref="HexColor"/> 
class HexColor : StringEnum<HexColor>
{
    public static readonly HexColor Blue = New("#FF0000");
    public static readonly HexColor Green = New("#00FF00");
    public static readonly HexColor Red = New("#000FF");

• Your StringEnum looks somewhat similar to a regular enum:

    // Static Parse Method
    HexColor.Parse("#FF0000") // => HexColor.Red
    HexColor.Parse("#ff0000", caseSensitive: false) // => HexColor.Red
    HexColor.Parse("invalid") // => throws InvalidOperationException

    // Static TryParse method.
    HexColor.TryParse("#FF0000") // => HexColor.Red
    HexColor.TryParse("#ff0000", caseSensitive: false) // => HexColor.Red
    HexColor.TryParse("invalid") // => null

    // Parse and TryParse returns the preexistent instances
    object.ReferenceEquals(HexColor.Parse("#FF0000"), HexColor.Red) // => true

    // Conversion from your `StringEnum` to `string`
    string myString1 = HexColor.Red.ToString(); // => "#FF0000"
    string myString2 = HexColor.Red; // => "#FF0000" (implicit cast)

• Intellisense will suggest the enum name if the class is annotated with the xml comment <completitionlist>. (Works in both C# and VB): i.e.

Instalation

Either:

• Install latest StringEnum NuGet package, which is based on .Net Standard 1.0 so it runs on .Net Core >= 1.0, .Net Framework >= 4.5, Mono >= 4.6, etc.
• Or paste the following StringEnum base class to your project. (latest version)

    public abstract class StringEnum<T> : IEquatable<T> where T : StringEnum<T>, new()
    {
        protected string Value;
        private static IList<T> valueList = new List<T>();
        protected static T New(string value)
        {
            if (value == null)
                return null; // the null-valued instance is null.

            var result = new T() { Value = value };
            valueList.Add(result);
            return result;
        }

        public static implicit operator string(StringEnum<T> enumValue) => enumValue.Value;
        public override string ToString() => Value;

        public static bool operator !=(StringEnum<T> o1, StringEnum<T> o2) => o1?.Value != o2?.Value;
        public static bool operator ==(StringEnum<T> o1, StringEnum<T> o2) => o1?.Value == o2?.Value;

        public override bool Equals(object other) => this.Value.Equals((other as T)?.Value ?? (other as string));
        bool IEquatable<T>.Equals(T other) => this.Value.Equals(other.Value);
        public override int GetHashCode() => Value.GetHashCode();

        /// <summary>
        /// Parse the <paramref name="value"/> specified and returns a valid <typeparamref name="T"/> or else throws InvalidOperationException.
        /// </summary>

        /// <param name="caseSensitive">If true, the strings must match case sensitivity.</param>
        public static T Parse(string value, bool caseSensitive = false)
        {
            var result = TryParse(value, caseSensitive);
            if (result == null)
                throw new InvalidOperationException((value == null ? "null" : $"'{value}'") + $" is not a valid {typeof(T).Name}");

            return result;
        }

        /// <summary>
        /// Parse the <paramref name="value"/> specified and returns a valid <typeparamref name="T"/> or else returns null.
        /// </summary>

        /// <param name="caseSensitive">If true, the strings must match case sensitivity.</param>
        public static T TryParse(string value, bool caseSensitive = false)
        {
            if (value == null) return null;
            if (valueList.Count == 0) System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor(typeof(T).TypeHandle); // force static fields initialization
            var field = valueList.FirstOrDefault(f => f.Value.Equals(value,
                    caseSensitive ? StringComparison.Ordinal
                                  : StringComparison.OrdinalIgnoreCase));
            // Not using InvariantCulture because it's only supported in NETStandard >= 2.0

            if (field == null)
                return null;

            return field;
        }
    }

I realized after the fact that this code is similar to Ben's answer. I sincerely wrote it from scratch. However I think it has a few extras, like the <completitionlist> hack, the resulting class looks more like an Enum, no use of reflection on Parse(), the NuGet package and repo where I will hopefully address incoming issues and feedback.

Wrap the label and input in another div with a defined height. This may not work in IE versions lower than 8.

position:absolute; 
top:0; bottom:0; left:0; right:0;
margin:auto;

Try to find $cfg['Servers'][$i]['password'] = ''; in config file located wamp/scripts/config.inc.php

Then set the password to your mysql password and refresh PhpmyAdmin

You can use the following:

OS=$(uname -s)

then you can use OS variable in your script.

In my case the issue was that Virtual directory was not created.

1. Right click on web project file and go to properties
2. Navigate to Web
3. Scroll down to Project Url
4. Click Create Virtual Directory button to create virtual directory

Here is one that works better for me (LINQPad version):

DateTime d;
DateTime.TryParseExact(
    "2010-08-20T15:00:00Z",
    @"yyyy-MM-dd\THH:mm:ss\Z",
    CultureInfo.InvariantCulture,
    DateTimeStyles.AssumeUniversal, 
    out d);
d.ToString()

produces

true

You have a good example here (Array of Function pointers), with the syntax detailed.

int sum(int a, int b);
int subtract(int a, int b);
int mul(int a, int b);
int div(int a, int b);

int (*p[4]) (int x, int y);

int main(void)
{
  int result;
  int i, j, op;

  p[0] = sum; /* address of sum() */
  p[1] = subtract; /* address of subtract() */
  p[2] = mul; /* address of mul() */
  p[3] = div; /* address of div() */
[...]

To call one of those function pointers:

result = (*p[op]) (i, j); // op being the index of one of the four functions

I updated your question with the code snippet. After proper indenting, it is immediately clear what the problem is: you use File.Create() but don't close the FileStream that it returns.

Doing it that way is unnecessary, StreamWriter already allows appending to an existing file and creating a new file if it doesn't yet exist. Like this:

  string filePath = string.Format(@"{0}\M{1}.dat", ConfigurationManager.AppSettings["DirectoryPath"], costCentre); 
  using (StreamWriter sw = new StreamWriter(filePath, true)) {
    //write my text 
  }

Which uses this StreamWriter constructor.

Another way of simply telling if an element exists is to check the count()

if (myset.count(x)) {
   // x is in the set, count is 1
} else {
   // count zero, i.e. x not in the set
}

Most of the times, however, I find myself needing access to the element wherever I check for its existence.

So I'd have to find the iterator anyway. Then, of course, it's better to simply compare it to end too.

set< X >::iterator it = myset.find(x);
if (it != myset.end()) {
   // do something with *it
}

C++ 20

In C++20 set gets a contains function, so the following becomes possible as mentioned at: https://stackoverflow.com/a/54197839/895245

if (myset.contains(x)) {
  // x is in the set
} else {
  // no x 
}

You need to add a 640x1136 pixels PNG image ([email protected]) as a 4 inch default splash image of your project, and it will use extra spaces (without efforts on simple table based applications, games will require more efforts).

I've created a small UIDevice category in order to deal with all screen resolutions. You can get it here, but the code is as follows:

File UIDevice+Resolutions.h:

enum {
    UIDeviceResolution_Unknown           = 0,
    UIDeviceResolution_iPhoneStandard    = 1,    // iPhone 1,3,3GS Standard Display  (320x480px)
    UIDeviceResolution_iPhoneRetina4    = 2,    // iPhone 4,4S Retina Display 3.5"  (640x960px)
    UIDeviceResolution_iPhoneRetina5     = 3,    // iPhone 5 Retina Display 4"       (640x1136px)
    UIDeviceResolution_iPadStandard      = 4,    // iPad 1,2,mini Standard Display   (1024x768px)
    UIDeviceResolution_iPadRetina        = 5     // iPad 3 Retina Display            (2048x1536px)
}; typedef NSUInteger UIDeviceResolution;

@interface UIDevice (Resolutions)

- (UIDeviceResolution)resolution;

NSString *NSStringFromResolution(UIDeviceResolution resolution);

@end

File UIDevice+Resolutions.m:

#import "UIDevice+Resolutions.h"

@implementation UIDevice (Resolutions)

- (UIDeviceResolution)resolution
{
    UIDeviceResolution resolution = UIDeviceResolution_Unknown;
    UIScreen *mainScreen = [UIScreen mainScreen];
    CGFloat scale = ([mainScreen respondsToSelector:@selector(scale)] ? mainScreen.scale : 1.0f);
    CGFloat pixelHeight = (CGRectGetHeight(mainScreen.bounds) * scale);

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
        if (scale == 2.0f) {
            if (pixelHeight == 960.0f)
                resolution = UIDeviceResolution_iPhoneRetina4;
            else if (pixelHeight == 1136.0f)
                resolution = UIDeviceResolution_iPhoneRetina5;

        } else if (scale == 1.0f && pixelHeight == 480.0f)
            resolution = UIDeviceResolution_iPhoneStandard;

    } else {
        if (scale == 2.0f && pixelHeight == 2048.0f) {
            resolution = UIDeviceResolution_iPadRetina;

        } else if (scale == 1.0f && pixelHeight == 1024.0f) {
            resolution = UIDeviceResolution_iPadStandard;
        }
    }

    return resolution;
 }

 @end

This is how you need to use this code.

1) Add the above UIDevice+Resolutions.h & UIDevice+Resolutions.m files to your project

2) Add the line #import "UIDevice+Resolutions.h" to your ViewController.m

3) Add this code to check what versions of device you are dealing with

int valueDevice = [[UIDevice currentDevice] resolution];

    NSLog(@"valueDevice: %d ...", valueDevice);

    if (valueDevice == 0)
    {
        //unknow device - you got me!
    }
    else if (valueDevice == 1)
    {
        //standard iphone 3GS and lower
    }
    else if (valueDevice == 2)
    {
        //iphone 4 & 4S
    }
    else if (valueDevice == 3)
    {
        //iphone 5
    }
    else if (valueDevice == 4)
    {
        //ipad 2
    }
    else if (valueDevice == 5)
    {
        //ipad 3 - retina display
    }

Take a look at your code :

 getUsers(): Observable<User[]> {
        return Observable.create(observer => {
            this.http.get('http://users.org').map(response => response.json();
        })
    }

and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)

 getHeroes(): Promise<Hero[]> {
    return this.http.get(this.heroesUrl)
               .toPromise()
               .then(response => response.json().data as Hero[])
               .catch(this.handleError);
  }

The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:

   return Observable.create(observer => {
        this.http.get('http://users.org').map(response => response.json()

Try to follow the guide in link that I provided. You should be just fine when you study it carefully.

---EDIT----

First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!

Try to do it like this:

  getUsers(): void {
        this.userService.getUsers()
            .then(users => {
               this.users = users
               console.log('this.users=' + this.users);
            });


    }

See where the console.log(...) is!

Try to resign from toPromise() it's seems to be just for ppl with no RxJs background.

Catch another link: https://scotch.io/tutorials/angular-2-http-requests-with-observables Build your service once again with RxJs observables.

You can use:

Integer grandChildCount = ((BigInteger) result[1]).intValue();

Or perhaps cast to Number to cover both Integer and BigInteger values.

According to the fine manual, createConnection() can be used to connect to multiple databases.

However, you need to create separate models for each connection/database:

var conn      = mongoose.createConnection('mongodb://localhost/testA');
var conn2     = mongoose.createConnection('mongodb://localhost/testB');

// stored in 'testA' database
var ModelA    = conn.model('Model', new mongoose.Schema({
  title : { type : String, default : 'model in testA database' }
}));

// stored in 'testB' database
var ModelB    = conn2.model('Model', new mongoose.Schema({
  title : { type : String, default : 'model in testB database' }
}));

I'm pretty sure that you can share the schema between them, but you have to check to make sure.

in your app dashboard check status to on

Refering to the answer given by @scottndecker to the following question, chrome now provides a 'disable JavaScript' option under Developer Tools:

• Vertical ... in upper right
• Settings
• And under 'Preferences' go to the 'Debugger' section at the very bottom and select 'Disable JavaScript'

Good thing is you can stop and rerun again just by checking/unchecking it.

I would not use .at for performance reasons.

Define a struct:

//#pragma pack(push, 2) //not useful (see comments below)
struct RGB {
    uchar blue;
    uchar green;
    uchar red;  };

And then use it like this on your cv::Mat image:

RGB& rgb = image.ptr<RGB>(y)[x];

image.ptr(y) gives you a pointer to the scanline y. And iterate through the pixels with loops of x and y

this kind of solution causes many problems like this. for consistency and SEO considerations redirect on the main domain is the best solution.

do it redirection at the server level

or any other level like route 53 if are using

Also if your app is precompiled you should have

PrecompiledApp.config

in the root folder of your app otherwise you could get HTTP Error 403.14 as well.

one line solution: basic idea:

$('sth').click(function () {
    let COND = $(this).propery == 'cond1' ? 'cond2' : 'cond1';
    doSomeThing(COND);
})

examples on jsfiddle

example 1, changing innerHTML of an element in a toggle-mode:

$('#clickTest1').click(function () {
    $(this).html($(this).html() == 'click Me' ? 'clicked' : 'click Me');
});

example 2, toggling displays between "none" and "inline-block":

$('#clickTest2, #clickTest2 > span').click(function () {
    $(this).children().css('display', $(this).children().css('display') == 'inline-block' ? 'none' : 'inline-block');
});

A static block executes once in the life cycle of any program, another property of static block is that it executes before the main method.

Code:

if(preg_match('/[^a-z_\-0-9]/i', $string))
{
  echo "not valid string";
}

Explanation:

• [] => character class definition
• ^ => negate the class
• a-z => chars from 'a' to 'z'
• _ => underscore
• - => hyphen '-' (You need to escape it)
• 0-9 => numbers (from zero to nine)

The 'i' modifier at the end of the regex is for 'case-insensitive' if you don't put that you will need to add the upper case characters in the code before by doing A-Z

Thanks for all your help! @Svetoslav Tsolov had it very close, but I was still getting an error, until I figured out the closing parenthesis was in the wrong place. Here's the final query that works:

SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID, 
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
(CASE WHEN dbo.EU_Admin3.EUID IS NULL THEN dbo.EU_Admin2.EUID ELSE dbo.EU_Admin3.EUID END) AS EUID
FROM dbo.AdminID 

LEFT OUTER JOIN dbo.EU_Admin2
ON dbo.AdminID.DistrictID = dbo.EU_Admin2.DistrictID

LEFT OUTER JOIN dbo.EU_Admin3
ON dbo.AdminID.ADMIN3_ID = dbo.EU_Admin3.ADMIN3_ID

Given

l1 = [a,b]
l2 = [b,a]

In Python >= 3.0

assertCountEqual(l1, l2) # True

In Python >= 2.7, the above function was named:

assertItemsEqual(l1, l2) # True

In Python < 2.7

import unittest2
assertItemsEqual(l1, l2) # True

Via six module (Any Python version)

import unittest
import six
class MyTest(unittest.TestCase):
    def test(self):
        six.assertCountEqual(self, self.l1, self.l2) # True

While a lot of the above answers give ways to embed an image using a file or with Python code, there is a way to embed an image in the jupyter notebook itself using only markdown and base64!

To view an image in the browser, you can visit the link data:image/png;base64,**image data here** for a base64-encoded PNG image, or data:image/jpg;base64,**image data here** for a base64-encoded JPG image. An example link can be found at the end of this answer.

To embed this into a markdown page, simply use a similar construct as the file answers, but with a base64 link instead: ![**description**](data:image/**type**;base64,**base64 data**). Now your image is 100% embedded into your Jupyter Notebook file!

Example link: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAABHNCSVQICAgIfAhkiAAAAD9JREFUGJW1jzEOADAIAqHx/1+mE4ltNXEpI3eJQknCIGsiHSLJB+aO/06PxOo/x2wBgKR2jCeEy0rOO6MDdzYQJRcVkl1NggAAAABJRU5ErkJggg==

Example markdown: ![smile](data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAABHNCSVQICAgIfAhkiAAAAD9JREFUGJW1jzEOADAIAqHx/1+mE4ltNXEpI3eJQknCIGsiHSLJB+aO/06PxOo/x2wBgKR2jCeEy0rOO6MDdzYQJRcVkl1NggAAAABJRU5ErkJggg==)

This code is better rewritten as:

for( Map.Entry me : entrys.entrySet() )
{
    this.add( (Component) me.getValue() );
}

and it is equivalent to:

for( Component comp : entrys.getValues() )
{
    this.add( comp );
}

When you enumerate the entries of a map, the iteration yields a series of objects which implement the Map.Entry interface. Each one of these objects contains a key and a value.

It is supposed to be slightly more efficient to enumerate the entries of a map than to enumerate its values, but this factoid presumes that your Map is a HashMap, and also presumes knowledge of the inner workings (implementation details) of the HashMap class. What can be said with a bit more certainty is that no matter how your map is implemented, (whether it is a HashMap or something else,) if you need both the key and the value of the map, then enumerating the entries is going to be more efficient than enumerating the keys and then for each key invoking the map again in order to look up the corresponding value.

Well, you could make it static:

static const int t = 100;

or you could use a member initializer:

T1() : t(100)
{
    // Other constructor stuff here
}

Important Update:

HttpModule and Http from @angular/http has been deprecated since Angular V5, should of using HttpClientModule and HttpClient from @angular/common/http instead, refer CHANGELOG.

For Angular version previous from **@4.3.0, You should inject Http from @angular/http, and HttpModule is for importing at your NgModule's import array.

import {HttpModule} from '@angular/http';

@NgModule({
  ...
  imports: [HttpModule]
})

Inject http at component or service

import { Http } from '@angular/http';

constructor(private http: Http) {}

For Angular version after(include) 4.3.0, you can use HttpClient from @angular/common/http instead of Http from @angular/http. Don't forget to import HttpClientModule at your NgModule's import array first.

Refer @echonax's answer.

The expression 'AND' and 'OR' and 'NOT' always evaluates to 'NOT', so you are effectively doing

while 'NOT' not in some_list:
    print 'No boolean operator'

You can either check separately for all of them

while ('AND' not in some_list and 
       'OR' not in some_list and 
       'NOT' not in some_list):
    # whatever

or use sets

s = set(["AND", "OR", "NOT"])
while not s.intersection(some_list):
    # whatever

I've had trouble with git revert in the past (mainly because I'm not quite certain how it works.) I've had trouble reverting because of merge problems..

My simple solution is this.

Step 1.

 git clone <your repos URL> .

your project in another folder, then:

Step 2.

git reset --hard <the commit you wanna go to>

then Step 3.

in your latest (and main) project dir (the one that has the problematic last commit) paste the files of step 2

Step 4.

git commit -m "Fixing the previous messy commit" 

Step 5.

Enjoy

It won't be fast, and there will be a lot for you to type (unless you generate the SQL from user_tab_columns), but here is what I use when I need to compare two tables row-by-row and column-by-column.

The query will return all rows that

• Exists in table1 but not in table2
• Exists in table2 but not in table1
• Exists in both tables, but have at least one column with a different value

(common identical rows will be excluded).

"PK" is the column(s) that make up your primary key. "a" will contain A if the present row exists in table1. "b" will contain B if the present row exists in table2.

select pk
      ,decode(a.rowid, null, null, 'A') as a
      ,decode(b.rowid, null, null, 'B') as b
      ,a.col1, b.col1
      ,a.col2, b.col2
      ,a.col3, b.col3
      ,...
  from table1 a 
  full outer 
  join table2 b using(pk)
 where decode(a.col1, b.col1, 1, 0) = 0
    or decode(a.col2, b.col2, 1, 0) = 0
    or decode(a.col3, b.col3, 1, 0) = 0
    or ...;

Edit Added example code to show the difference described in comment. Whenever one of the values contains NULL, the result will be different.

with a as(
   select 0    as col1 from dual union all
   select 1    as col1 from dual union all
   select null as col1 from dual
)
,b as(
   select 1    as col1 from dual union all
   select 2    as col1 from dual union all
   select null as col1 from dual
)   
select a.col1

Adding one more point. Function declarations with default argument should be ordered from right to left and from top to bottom.

For example in the below function declaration if you change the declaration order then the compiler gives you a missing default parameter error. Reason the compiler allows you to separate the function declaration with default argument within the same scope but it should be in order from RIGHT to LEFT (default arguments) and from TOP to BOTTOM(order of function declaration default argument).

//declaration
void function(char const *msg, bool three, bool two, bool one = false);
void function(char const *msg, bool three = true, bool two, bool one); // Error 
void function(char const *msg, bool three, bool two = true, bool one); // OK
//void function(char const *msg, bool three = true, bool two, bool one); // OK

int main() {
    function("Using only one Default Argument", false, true);
    function("Using Two Default Arguments", false);
    function("Using Three Default Arguments");
    return 0;
}

//definition
void function(char const *msg, bool three, bool two, bool one ) {
    std::cout<<msg<<" "<<three<<" "<<two<<" "<<one<<std::endl;
}

The issue is how you're attempting to get the value. Things like...

if ( document.frm_new_user_request.u_isid.value == '' )

won't work. You need to find the element you want to get the value of first. It's not quite like a server side language where you can type in an object's reference name and a period to get or assign values.

document.getElementById('[id goes here]').value;

will work. Note: JavaScript is case-sensitive

I would recommend using:

var variablename = document.getElementById('[id goes here]');

or

var variablename = document.getElementById('[id goes here]').value;

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

I fixed mine by adding these lines on my IIS webconfig.

<httpErrors>
    <remove statusCode="405" subStatusCode="-1" />
    <error statusCode="405" prefixLanguageFilePath="" path="/my-page.htm" responseMode="ExecuteURL" />

Need to add package

sudo apt-get install libpq-dev

to install pg gem in RoR

You most likely just need to format your integer:

'%0*d' % (fill, your_int)

For example,

>>> '%0*d' % (3, 4)
'004'

This is my favorite as it makes the most human readable sense:

A better way to normalize your image is to take each value and divide by the largest value experienced by the data type. This ensures that images that have a small dynamic range in your image remain small and they're not inadvertently normalized so that they become gray. For example, if your image had a dynamic range of [0-2], the code right now would scale that to have intensities of [0, 128, 255]. You want these to remain small after converting to np.uint8.

Therefore, divide every value by the largest value possible by the image type, not the actual image itself. You would then scale this by 255 to produced the normalized result. Use numpy.iinfo and provide it the type (dtype) of the image and you will obtain a structure of information for that type. You would then access the max field from this structure to determine the maximum value.

So with the above, do the following modifications to your code:

import numpy as np
import cv2
[...]
info = np.iinfo(data.dtype) # Get the information of the incoming image type
data = data.astype(np.float64) / info.max # normalize the data to 0 - 1
data = 255 * data # Now scale by 255
img = data.astype(np.uint8)
cv2.imshow("Window", img)

Note that I've additionally converted the image into np.float64 in case the incoming data type is not so and to maintain floating-point precision when doing the division.

!moment(yourDate).isBefore(moment(), "day");

If you run ps -aux | dockerd you should see the tcp endpoint it is running on.

You can directly cast it:

enum MyMonthEnum { January = 1, February, March, April, May, June, July, August, September, October, November, December };

public static string GetMyMonthName(int MonthIndex)
{
  MyMonthEnum MonthName = (MyMonthEnum)MonthIndex;
  return MonthName.ToString();
}

For Example:

string MySelectedMonthName=GetMyMonthName(8);
 //then MySelectedMonthName value will be August.

The convention for out of range in JavaScript is using RangeError. To check the type use if / else + instanceof starting at the most specific to the most generic

try {
    throw new RangeError();
}
catch (e){
    if (e instanceof RangeError){
        console.log('out of range');
    } else { 
        throw; 
    }
}

Add this to your css:

html, body {
    height:100%;
}

If you say height:100%, you mean '100% of the parent element'. If the parent element has no specified height, nothing will happen. You only set 100% on body, but you also need to add it to html.

As you said the event window.onbeforeunload fires when the users clicks on a link or refreshes the page, so it would not a good even to end a session.

http://msdn.microsoft.com/en-us/library/ms536907(VS.85).aspx describes all situations where window.onbeforeonload is triggered. (IE)

However, you can place a JavaScript global variable on your pages to identify actions that should not trigger a logoff (by using an AJAX call from onbeforeonload, for example).

The script below relies on JQuery

/*
* autoLogoff.js
*
* Every valid navigation (form submit, click on links) should
* set this variable to true.
*
* If it is left to false the page will try to invalidate the
* session via an AJAX call
*/
var validNavigation = false;

/*
* Invokes the servlet /endSession to invalidate the session.
* No HTML output is returned
*/
function endSession() {
   $.get("<whatever url will end your session>");
}

function wireUpEvents() {

  /*
  * For a list of events that triggers onbeforeunload on IE
  * check http://msdn.microsoft.com/en-us/library/ms536907(VS.85).aspx
  */
  window.onbeforeunload = function() {
      if (!validNavigation) {
         endSession();
      }
  }

  // Attach the event click for all links in the page
  $("a").bind("click", function() {
     validNavigation = true;
  });

  // Attach the event submit for all forms in the page
  $("form").bind("submit", function() {
     validNavigation = true;
  });

}

// Wire up the events as soon as the DOM tree is ready
$(document).ready(function() {
    wireUpEvents();  
});

This script may be included in all pages

<script type="text/javascript" src="js/autoLogoff.js"></script>

Let's go through this code:

  var validNavigation = false;

  window.onbeforeunload = function() {
      if (!validNavigation) {
         endSession();
      }
  }

  // Attach the event click for all links in the page
  $("a").bind("click", function() {
     validNavigation = true;
  });

  // Attach the event submit for all forms in the page
  $("form").bind("submit", function() {
     validNavigation = true;
  });

A global variable is defined at page level. If this variable is not set to true then the event windows.onbeforeonload will terminate the session.

An event handler is attached to every link and form in the page to set this variable to true, thus preventing the session from being terminated if the user is just submitting a form or clicking on a link.

function endSession() {
   $.get("<whatever url will end your session>");
}

The session is terminated if the user closed the browser/tab or navigated away. In this case the global variable was not set to true and the script will do an AJAX call to whichever URL you want to end the session

This solution is server-side technology agnostic. It was not exaustively tested but it seems to work fine in my tests

Here is a great answer to that:

SET sql_mode='PIPES_AS_CONCAT';

Find more here: https://stackoverflow.com/a/24777235/4120319

Here's the full SQL:

SET sql_mode='PIPES_AS_CONCAT';

SELECT * FROM tableOne 
LEFT JOIN tableTwo
ON tableTwo.query = 'category_id=' || tableOne.category_id;

Using example file /Users/Jonathan/Scripts/bash/MyScript.sh, this code:

MY_EXT=".${0##*.}"
ME=$(/usr/bin/basename "${0}" "${MY_EXT}")

will result in ${ME} being MyScript and ${MY_EXT} being .sh:

Script:

#!/bin/bash
set -e

MY_EXT=".${0##*.}"
ME=$(/usr/bin/basename "${0}" "${MY_EXT}")

echo "${ME} - ${MY_EXT}"

Some tests:

$ ./MyScript.sh 
MyScript - .sh

$ bash MyScript.sh
MyScript - .sh

$ /Users/Jonathan/Scripts/bash/MyScript.sh
MyScript - .sh

$ bash /Users/Jonathan/Scripts/bash/MyScript.sh
MyScript - .sh

You can also use this script to figure out more info:

EXEC sp_server_info

The result will be something like that:

When using Node.js, you can retrieve environment variables by key from the process.env object:

for example

var mode   = process.env.NODE_ENV;
var apiKey = process.env.apiKey; // '42348901293989849243'

Here is the answer that will explain setting environment variables in node.js

IIS webpage by using IP address

In IIS Management : Choose Site, then Bindings.

Add

• Type : http
• HostName : Empty
• Port : 80
• IP Address : Choose from drop-down menu the IP you need (usually there is only one IP)

Try This :

document.getElementById(<element_ID>).readOnly=true;

Use the splice method.

ArrayName.splice(indexValueOfArray,1);

This removes 1 item from the array starting at indexValueOfArray.

std::min and std::max are templates. So, they can be used on a variety of types that provide the less than operator, including floats, doubles, long doubles. So, if you wanted to write generic C++ code you'd do something like this:

template<typename T>
T const& max3(T const& a, T const& b, T const& c)
{
   using std::max;
   return max(max(a,b),c); // non-qualified max allows ADL
}

As for performance, I don't think fmin and fmax differ from their C++ counterparts.

In many cases, this may be an XY Problem. Why are you indexing your dictionary keys by position? Do you really need to? Until recently, dictionaries were not even ordered in Python, so accessing the first element was arbitrary.

I just translated some Python 2 code to Python 3:

keys = d.keys()
for (i, res) in enumerate(some_list):
    k = keys[i]
    # ...

which is not pretty, but not very bad either. At first, I was about to replace it by the monstrous

    k = next(itertools.islice(iter(keys), i, None))

before I realised this is all much better written as

for (k, res) in zip(d.keys(), some_list):

which works just fine.

I believe that in many other cases, indexing dictionary keys by position can be avoided. Although dictionaries are ordered in Python 3.7, relying on that is not pretty. The code above only works because the contents of some_list had been recently produced from the contents of d.

Have a hard look at your code if you really need to access a disk_keys element by index. Perhaps you don't need to.

   $url='the/url/you/want/to/go';
   echo '<META HTTP-EQUIV=REFRESH CONTENT="1; '.$url.'">';

this works for me fine.

The sort command prints the result of the sorting operation to standard output by default. In order to achieve an "in-place" sort, you can do this:

sort -o file file

This overwrites the input file with the sorted output. The -o switch, used to specify an output, is defined by POSIX, so should be available on all version of sort:

-o Specify the name of an output file to be used instead of the standard output. This file can be the same as one of the input files.

If you are unfortunate enough to have a version of sort without the -o switch (Luis assures me that they exist), you can achieve an "in-place" edit in the standard way:

sort file > tmp && mv tmp file

[OOT]

A bit OOT, but this question is the most closest topic with my question.

Here is an example if you want to show Event where ALL participant meet certain requirement. Let's say, event where ALL the participant has fully paid. So, it WILL NOT return events which having one or more participants that haven't fully paid .

Simply use the whereDoesntHave of the others 2 statuses.

Let's say the statuses are haven't paid at all [eq:1], paid some of it [eq:2], and fully paid [eq:3]

Event::whereDoesntHave('participants', function ($query) {
   return $query->whereRaw('payment = 1 or payment = 2');
})->get();

Need to see whether you got ant folder moved by mistake or unknowingly. It is set in environment variables.I resolved this once as mentioned below.

I removed ant folder by mistake and placed in another folder.I went to command prompt and typed "path". It has given me path as "F:\apache-ant-1.9.4\". So I moved the ant back to F drive and it resolved the issue.

You could alter the figsize by passing a tuple showing the width, height parameters you would like to keep.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(figsize=(10,10))         # Sample figsize in inches
sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5, ax=ax)

EDIT

I remember answering a similar question of yours where you had to set the index as TIMESTAMP. So, you could then do something like below:

df = df.set_index('TIMESTAMP')
df.resample('30min').mean()
fig, ax = plt.subplots()
ax = sns.heatmap(df.iloc[:, 1:6:], annot=True, linewidths=.5)
ax.set_yticklabels([i.strftime("%Y-%m-%d %H:%M:%S") for i in df.index], rotation=0)

For the head of the dataframe you posted, the plot would look like:

Updated package.json:

"build": {
  "appId": "com.my-website.my-app",
  "productName": "MyApp",
  "copyright": "Copyright © 2019 ${author}",
  "mac": {
    "icon": "./public/icons/mac/icon.icns",     <---------- set Mac Icons
    "category": "public.app-category.utilities"
  },
  "win": {
    "icon": "./public/icons/png/256x256.png" <---------- set Win Icon
  },
  "files": [
    "./build/**/*",
    "./dist/**/*",
    "./node_modules/**/*",
    "./public/**/*",       <---------- need for get access to icons
    "*.js"
  ],
  "directories": {
    "buildResources": "public" <---------- folder where placed icons
  }
},

After build application you can see icons. This solution don't show icons in developer mode. I don't setup icons in new BrowserWindow().

You cannot access a local directory from pl/sql. If you use bfile, you will setup a directory (create directory) on the server where Oracle is running where you will need to put your images.

If you want to insert a handful of images from your local machine, you'll need a client side app to do this. You can write your own, but I typically use Toad for this. In schema browser, click onto the table. Click the data tab, and hit + sign to add a row. Double click the BLOB column, and a wizard opens. The far left icon will load an image into the blob:

SQL Developer has a similar feature. See the "Load" link below:

If you need to pull images over the wire, you can do it using pl/sql, but its not straight forward. First, you'll need to setup ACL list access (for security reasons) to allow a user to pull over the wire. See this article for more on ACL setup.

Assuming ACL is complete, you'd pull the image like this:

declare
    l_url varchar2(4000) := 'http://www.oracleimg.com/us/assets/12_c_navbnr.jpg';
    l_http_request   UTL_HTTP.req;
    l_http_response  UTL_HTTP.resp;
    l_raw RAW(2000);
    l_blob BLOB;
begin
   -- Important: setup ACL access list first!

    DBMS_LOB.createtemporary(l_blob, FALSE);

    l_http_request  := UTL_HTTP.begin_request(l_url);
    l_http_response := UTL_HTTP.get_response(l_http_request);

  -- Copy the response into the BLOB.
  BEGIN
    LOOP
      UTL_HTTP.read_raw(l_http_response, l_raw, 2000);
      DBMS_LOB.writeappend (l_blob, UTL_RAW.length(l_raw), l_raw);
    END LOOP;
  EXCEPTION
    WHEN UTL_HTTP.end_of_body THEN
      UTL_HTTP.end_response(l_http_response);
  END;

  insert into my_pics (pic_id, pic) values (102, l_blob);
  commit;

  DBMS_LOB.freetemporary(l_blob); 
end;

Hope that helps.

As mentioned in several answers already that have been already given, you can use ToShorDateString():

DateTime.Now.ToShortDateString();

However, you may be a bit blocked if you also want to use the culture as a parameter. In this case you can use the ToString() method with the "d" format:

DateTime.Now.ToString("d", CultureInfo.GetCultureInfo("en-US"))

If you still want to create date using dashes, you can use this format:

var date = new Date('2013-08-31T17:00:00Z')

But bear in mind, that it creates time according to UTC. Meaning, if you live in GMT+3 (3 hours ahead of GMT) timezone, it will add this timezone offset to the time. So the above example will have this value, if GMT+3 (note that it is hour 20:00 and not 17:00):

Sat Aug 31 2013 20:00:00 GMT+0300 (FLE Standard Time)

Be sure to add 'Z' letter at the end, because otherwise Chrome and Firefox will parse the string differently (one will add time offset and the other won't).

A small variation but nothing new infact. It's really missing a feature...

select info->>'name' from rabbits 
where '"carrots"' = ANY (ARRAY(
    select * from json_array_elements(info->'food'))::text[]);

String array=new String[]; and String array=new String[]{}; both are invalid statement in java.

It will gives you an error that you are trying to assign String array to String datatype. More specifically error is like this Type mismatch: cannot convert from String[] to String

There could be a global variable, likely set with argparse from sys.argv, that stands for whether the program should be verbose or not. Then a decorator could be written such that if verbosity was on, then the standard input would be diverted into the null device as long as the function were to run:

import os
from contextlib import redirect_stdout
verbose = False

def louder(f):
    def loud_f(*args, **kwargs):
        if not verbose:
            with open(os.devnull, 'w') as void:
                with redirect_stdout(void):
                    return f(*args, **kwargs)
        return f(*args, **kwargs)
    return loud_f

@louder
def foo(s):
    print(s*3)

foo("bar")

This answer is inspired by this code; actually, I was going to just use it as a module in my program, but I got errors I couldn't understand, so I adapted a portion of it.

The downside of this solution is that verbosity is binary, unlike with logging, which allows for finer-tuning of how verbose the program can be. Also, all print calls are diverted, which might be unwanted for.

I assume that you have a .cer file containing PKCS#7-encoded certificate data and you want to convert it to PEM-encoded certificate data (typically a .crt or .pem file). For instance, a .cer file containing PKCS#7-encoded data looks like this:

-----BEGIN PKCS7-----
MIIW4gYJKoZIhvcNAQcCoIIW0zCCFs8CAQExADALBgkqhkiG9w0BBwGggha1MIIH
...
POI9n9cd2cNgQ4xYDiKWL2KjLB+6rQXvqzJ4h6BUcxm1XAX5Uj5tLUUL9wqT6u0G
+bKhADEA
-----END PKCS7-----

PEM certificate data looks like this:

-----BEGIN CERTIFICATE-----
MIIHNjCCBh6gAwIBAgIQAlBxtqKazsxUSR9QdWWxaDANBgkqhkiG9w0BAQUFADBm
...
nv72c/OV4nlyrvBLPoaS5JFUJvFUG8RfAEY=
-----END CERTIFICATE-----

There is an OpenSSL command that will convert .cer files (with PKCS#7 data) to the PEM data you may be expecting to encounter (the BEGIN CERTIFICATE block in the example above). You can coerce PKCS#7 data into PEM format by this command on a file we'll call certfile.cer:

openssl pkcs7 -text -in certfile.cer -print_certs -outform PEM -out certfile.pem

Note that a .cer or .pem file might contain one or more certificates (possibly the entire certificate chain).

Another use case is when using the SQL Server 2016+ functionality of AT TIME ZONE

The below statement will return a date converted to GMT

SELECT 
CONVERT(DATETIME, SWITCHOFFSET([ColumnA], DATEPART(TZOFFSET, [ColumnA] AT TIME ZONE 'GMT Standard Time')))

If you want to pass the time zone as a variable, say:

SELECT 
CONVERT(DATETIME, SWITCHOFFSET([ColumnA], DATEPART(TZOFFSET, [ColumnA] AT TIME ZONE @TimeZone)))

then that variable needs to be of the type sysname (declaring it as varchar will cause an error).

For the answer above, the default serial port is

        serialParams.BaudRate = 9600;
        serialParams.ByteSize = 8;
        serialParams.StopBits = TWOSTOPBITS;
        serialParams.Parity = NOPARITY;

Note: Do not run this command on a folder including a git repo - changes to .git could corrupt your git index.

find /home/www/ -type f -exec \
    sed -i 's/subdomainA\.example\.com/subdomainB.example.com/g' {} +

Compared to other answers here, this is simpler than most and uses sed instead of perl, which is what the original question asked for.

The 2nd argument to moment() is a parsing format rather than an display format.

For that, you want the .format() method:

moment(testDate).format('MM/DD/YYYY');

Also note that case does matter. For Month, Day of Month, and Year, the format should be uppercase.

/^(?!my).*/

(?!expression) is a negative lookahead; it matches a position where expression doesn't match starting at that position.

You need to use \n inside quotes.

document.getElementById("address_box").value = (title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4)

\n is called a EOL or line-break, \n is a common EOL marker and is commonly refereed to as LF or line-feed, it is a special ASCII character

Not sure about your question - "sideways" is the same as "landscape".

If you mean how to switch during runtime:

• Switch to previous layout orientation (for example, portrait, landscape): KEYPAD_7, Ctrl + F11
• Switch to next layout orientation (for example, portrait, landscape): KEYPAD_9, Ctrl + F12

Combining Alaa Akoum and Nick Eagle's solutions allowed me to loop through a series of windows services and stop them if they're running.

# stop the following Windows services in the specified order:
[Array] $Services = 'Service1','Service2','Service3','Service4','Service5';

# loop through each service, if its running, stop it
foreach($ServiceName in $Services)
{
    $arrService = Get-Service -Name $ServiceName
    write-host $ServiceName
    while ($arrService.Status -eq 'Running')
    {
        Stop-Service $ServiceName
        write-host $arrService.status
        write-host 'Service stopping'
        Start-Sleep -seconds 60
        $arrService.Refresh()
        if ($arrService.Status -eq 'Stopped')
            {
              Write-Host 'Service is now Stopped'
            }
     }
 }

The same can be done to start a series of service if they are not running:

# start the following Windows services in the specified order:
[Array] $Services = 'Service1','Service2','Service3','Service4','Service5';

# loop through each service, if its not running, start it
foreach($ServiceName in $Services)
{
    $arrService = Get-Service -Name $ServiceName
    write-host $ServiceName
    while ($arrService.Status -ne 'Running')
    {
        Start-Service $ServiceName
        write-host $arrService.status
        write-host 'Service starting'
        Start-Sleep -seconds 60
        $arrService.Refresh()
        if ($arrService.Status -eq 'Running')
        {
          Write-Host 'Service is now Running'
        }
    }
}

Reason to that is with the new update, they changed the URL for the Android Developer Tools update site to require HTTPS. If you are updating ADT, make sure you use HTTPS in the URL for the Android Developer Tools update site.

To find all valid address list this is the code I have used

public static IEnumerable<string> GetAddresses()
{
      var host = Dns.GetHostEntry(Dns.GetHostName());
      return (from ip in host.AddressList where ip.AddressFamily == AddressFamily.lo select ip.ToString()).ToList();
}

The only software that I found that already exists is Matrox PowerDesk. Among other things it lets you split a monitor into 2 virtual desktops. You have to have a compatible matrox video card though. It also does a bunch of other multi-monitor functions.

default port of mysql is 3306

default pot of sql server is 1433

The "double quote" + 'single quote' combo is not needed

console.log( $('#'+d) ); // single quotes only
console.log( $("#"+d) ); // double quotes only

Your selector results like this, which is overkill with the quotes:

$('"#abc"') // -> it'll try to find  <div id='"#abc"'>

// In css, this would be the equivalent:
"#abc"{ /* Wrong */ } // instead of:
#abc{ /* Right */ }

Yes, __attribute__((packed)) is potentially unsafe on some systems. The symptom probably won't show up on an x86, which just makes the problem more insidious; testing on x86 systems won't reveal the problem. (On the x86, misaligned accesses are handled in hardware; if you dereference an int* pointer that points to an odd address, it will be a little slower than if it were properly aligned, but you'll get the correct result.)

On some other systems, such as SPARC, attempting to access a misaligned int object causes a bus error, crashing the program.

There have also been systems where a misaligned access quietly ignores the low-order bits of the address, causing it to access the wrong chunk of memory.

Consider the following program:

#include <stdio.h>
#include <stddef.h>
int main(void)
{
    struct foo {
        char c;
        int x;
    } __attribute__((packed));
    struct foo arr[2] = { { 'a', 10 }, {'b', 20 } };
    int *p0 = &arr[0].x;
    int *p1 = &arr[1].x;
    printf("sizeof(struct foo)      = %d\n", (int)sizeof(struct foo));
    printf("offsetof(struct foo, c) = %d\n", (int)offsetof(struct foo, c));
    printf("offsetof(struct foo, x) = %d\n", (int)offsetof(struct foo, x));
    printf("arr[0].x = %d\n", arr[0].x);
    printf("arr[1].x = %d\n", arr[1].x);
    printf("p0 = %p\n", (void*)p0);
    printf("p1 = %p\n", (void*)p1);
    printf("*p0 = %d\n", *p0);
    printf("*p1 = %d\n", *p1);
    return 0;
}

On x86 Ubuntu with gcc 4.5.2, it produces the following output:

sizeof(struct foo)      = 5
offsetof(struct foo, c) = 0
offsetof(struct foo, x) = 1
arr[0].x = 10
arr[1].x = 20
p0 = 0xbffc104f
p1 = 0xbffc1054
*p0 = 10
*p1 = 20

On SPARC Solaris 9 with gcc 4.5.1, it produces the following:

sizeof(struct foo)      = 5
offsetof(struct foo, c) = 0
offsetof(struct foo, x) = 1
arr[0].x = 10
arr[1].x = 20
p0 = ffbff317
p1 = ffbff31c
Bus error

In both cases, the program is compiled with no extra options, just gcc packed.c -o packed.

(A program that uses a single struct rather than array doesn't reliably exhibit the problem, since the compiler can allocate the struct on an odd address so the x member is properly aligned. With an array of two struct foo objects, at least one or the other will have a misaligned x member.)

(In this case, p0 points to a misaligned address, because it points to a packed int member following a char member. p1 happens to be correctly aligned, since it points to the same member in the second element of the array, so there are two char objects preceding it -- and on SPARC Solaris the array arr appears to be allocated at an address that is even, but not a multiple of 4.)

When referring to the member x of a struct foo by name, the compiler knows that x is potentially misaligned, and will generate additional code to access it correctly.

Once the address of arr[0].x or arr[1].x has been stored in a pointer object, neither the compiler nor the running program knows that it points to a misaligned int object. It just assumes that it's properly aligned, resulting (on some systems) in a bus error or similar other failure.

Fixing this in gcc would, I believe, be impractical. A general solution would require, for each attempt to dereference a pointer to any type with non-trivial alignment requirements either (a) proving at compile time that the pointer doesn't point to a misaligned member of a packed struct, or (b) generating bulkier and slower code that can handle either aligned or misaligned objects.

I've submitted a gcc bug report. As I said, I don't believe it's practical to fix it, but the documentation should mention it (it currently doesn't).

UPDATE: As of 2018-12-20, this bug is marked as FIXED. The patch will appear in gcc 9 with the addition of a new -Waddress-of-packed-member option, enabled by default.

When address of packed member of struct or union is taken, it may result in an unaligned pointer value. This patch adds -Waddress-of-packed-member to check alignment at pointer assignment and warn unaligned address as well as unaligned pointer

I've just built that version of gcc from source. For the above program, it produces these diagnostics:

c.c: In function ‘main’:
c.c:10:15: warning: taking address of packed member of ‘struct foo’ may result in an unaligned pointer value [-Waddress-of-packed-member]
   10 |     int *p0 = &arr[0].x;
      |               ^~~~~~~~~
c.c:11:15: warning: taking address of packed member of ‘struct foo’ may result in an unaligned pointer value [-Waddress-of-packed-member]
   11 |     int *p1 = &arr[1].x;
      |               ^~~~~~~~~

Here is a solution without eval nor $() nor `` :

ord () {
 local s
 printf -v s '\\%03o' $1
 printf "$s"
}

ord 65

Even though this has been answered already, I'm adding this note for an alternative approach.

I wanted to place a known number of items into an array, into specific positions, as they come off of an "associative array" (i.e. an object) which by definition is not guaranteed to be in a sorted order. I wanted the resulting array to be an array of objects, but the objects to be in a specific order in the array since an array guarantees their order. So I did this.

First the source object, a JSONB string retrieved from PostgreSQL. I wanted to have it sorted by the "order" property in each child object.

var jsonb_str = '{"one": {"abbr": "", "order": 3}, "two": {"abbr": "", "order": 4}, "three": {"abbr": "", "order": 5}, "initialize": {"abbr": "init", "order": 1}, "start": {"abbr": "", "order": 2}}';

var jsonb_obj = JSON.parse(jsonb_str);

Since the number of nodes in the object is known, I first create an array with the specified length:

var obj_length = Object.keys(jsonb_obj).length;
var sorted_array = new Array(obj_length);

And then iterate the object, placing the newly created temporary objects into the desired locations in the array without really any "sorting" taking place.

for (var key of Object.keys(jsonb_obj)) {
  var tobj = {};
  tobj[key] = jsonb_obj[key].abbr;

  var position = jsonb_obj[key].order - 1;
  sorted_array[position] = tobj;
}

console.dir(sorted_array);

The easiest way to set the version in Android Studio:

1. Press SHIFT+CTRL+ALT+S (or File -> Project Structure -> app)

Android Studio < 3.4:

2. Choose tab 'Flavors'
3. The last two fields are 'Version Code' and 'Version Name'

Android Studio >= 3.4:

2. Choose 'Modules' in the left panel.
3. Choose 'app' in middle panel.
4. Choose 'Default Config' tab in the right panel.
5. Scroll down to see and edit 'Version Code' and 'Version Name' fields.

I just Added

jQuery.datetimepicker.setLocale('fr');

and It's worked

<hostA_shell_prompt>$ ssh user@hostB "ls -la"

That will prompt you for password, unless you have copied your hostA user's public key to the authorized_keys file on the home of user .ssh's directory. That will allow for passwordless authentication (if accepted as an auth method on the ssh server's configuration)

If I understand right, you've made a commit to changed_branch and you want to copy that commit to other_branch? Easy:

git checkout other_branch
git cherry-pick changed_branch

All of the suggestions above work, but if you want your computations to by more efficient, you should take advantage of numpy vector operations (as pointed out here).

import pandas as pd
import numpy as np


df = pd.DataFrame ({'a' : np.random.randn(6),
             'b' : ['foo', 'bar'] * 3,
             'c' : np.random.randn(6)})

Example 1: looping with pandas.apply():

%%timeit
def my_test2(row):
    return row['a'] % row['c']

df['Value'] = df.apply(my_test2, axis=1)

The slowest run took 7.49 times longer than the fastest. This could mean that an intermediate result is being cached. 1000 loops, best of 3: 481 µs per loop

Example 2: vectorize using pandas.apply():

%%timeit
df['a'] % df['c']

The slowest run took 458.85 times longer than the fastest. This could mean that an intermediate result is being cached. 10000 loops, best of 3: 70.9 µs per loop

Example 3: vectorize using numpy arrays:

%%timeit
df['a'].values % df['c'].values

The slowest run took 7.98 times longer than the fastest. This could mean that an intermediate result is being cached. 100000 loops, best of 3: 6.39 µs per loop

So vectorizing using numpy arrays improved the speed by almost two orders of magnitude.

$start_date="17/02/2012";
$end_date="21/02/2012";
$date_from_user="19/02/2012";

function geraTimestamp($data)
{
    $partes = explode('/', $data); 
    return mktime(0, 0, 0, $partes[1], $partes[0], $partes[2]);
}


$startDatedt = geraTimestamp($start_date); 
$endDatedt = geraTimestamp($end_date);
$usrDatedt = geraTimestamp($date_from_user);

if (($usrDatedt >= $startDatedt) && ($usrDatedt <= $endDatedt))
{ 
    echo "Dentro";
}    
else
{
    echo "Fora";
}

I found the problem. This code was placed in a separate file that was added with a php include() function. And this include was happening before the Bootstrap files were loaded. So the Bootstrap JS file was not loaded yet, causing this modal to not do anything.

With the above code sample is nothing wrong and works as intended when placed in the body part of a html page.

<script type="text/javascript">
$('#memberModal').modal('show');
</script>

If you use a web-app there is also another way to access the application context without using singletons by using a servletfilter and a ThreadLocal. In the filter you can access the application context using WebApplicationContextUtils and store either the application context or the needed beans in the TheadLocal.

Caution: if you forget to unset the ThreadLocal you will get nasty problems when trying to undeploy the application! Thus, you should set it and immediately start a try that unsets the ThreadLocal in the finally-part.

Of course, this still uses a singleton: the ThreadLocal. But the actual beans do not need to be anymore. The can even be request-scoped, and this solution also works if you have multiple WARs in an Application with the libaries in the EAR. Still, you might consider this use of ThreadLocal as bad as the use of plain singletons. ;-)

Perhaps Spring already provides a similar solution? I did not find one, but I don't know for sure.

With Jquery you can do this with one simple codeline.

HTML:

<input id="email" name="email">

Code:

$(email).on('paste', false);

JSfiddle: https://jsfiddle.net/ZjR9P/2/

You probably forgot to set the form's KeyPreview property to True. Overriding the ProcessCmdKey() method is the generic solution:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
  if (keyData == (Keys.Control | Keys.F)) {
    MessageBox.Show("What the Ctrl+F?");
    return true;
  }
  return base.ProcessCmdKey(ref msg, keyData);
}

First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.

After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

This is due to the series df[cat] containing elements that have varying data types e.g.(strings and/or floats). This could be due to the way the data is read, i.e. numbers are read as float and text as strings or the datatype was float and changed after the fillna operation.

In other words

pandas data type 'Object' indicates mixed types rather than str type

so using the following line:

df[cat] = le.fit_transform(df[cat].astype(str))

should help

According to the React Documentation it's perfectly OK to call setState() from within the componentDidMount() function.

It will cause render() to be called twice, which is less efficient than only calling it once, but other than that it's perfectly fine.

You can find the documentation here:

https://reactjs.org/docs/react-component.html#componentdidmount

Here is the excerpt from the documentation:

You may call setState() immediately in componentDidMount(). It will trigger an extra rendering, but it will happen before the browser updates the screen. This guarantees that even though the render() will be called twice in this case, the user won’t see the intermediate state. Use this pattern with caution because it often causes performance issues...

Try creating a javascript function which runs this:

document.getElementById("youriframeid").contentWindow.location.reload(true);

Or maybe use an HTML workaround:

Both might be what you're looking for...

Please take a look at the Android documentation.

Using the Bluetooth APIs, an Android application can perform the following:

• Scan for other Bluetooth devices
• Query the local Bluetooth adapter for paired Bluetooth devices
• Establish RFCOMM channels
• Connect to other devices through service discovery
• Transfer data to and from other devices
• Manage multiple connections

I've resorted to

df[ (df[column_name].notnull()) & (df[column_name]!=u'') ].index

lately. That gets both null and empty-string cells in one go.

James Gosling likened designing Java to the following:

"There's this principle about moving, when you move from one apartment to another apartment. An interesting experiment is to pack up your apartment and put everything in boxes, then move into the next apartment and not unpack anything until you need it. So you're making your first meal, and you're pulling something out of a box. Then after a month or so you've used that to pretty much figure out what things in your life you actually need, and then you take the rest of the stuff -- forget how much you like it or how cool it is -- and you just throw it away. It's amazing how that simplifies your life, and you can use that principle in all kinds of design issues: not do things just because they're cool or just because they're interesting."

You can read the context of the quote here

Basically operator overloading is great for a class that models some kind of point, currency or complex number. But after that you start running out of examples fast.

Another factor was the abuse of the feature in C++ by developers overloading operators like '&&', '||', the cast operators and of course 'new'. The complexity resulting from combining this with pass by value and exceptions is well covered in the Exceptional C++ book.

Just thought I would help somebody with this.

Typically, you can just paste this in console.

$("body").css({"overflow":"visible"});

Or, the javascript only version:

document.body.style.overflow = "visible";

This article may be useful too http://mito-team.com/article/2012/collapse-button-for-ckeditor-for-drupal

There are code samples and step-by-step guide about building your own CKEditor plugin with custom button.

In order to avoid this kind of ClassCastException, if you have:

class A
class B extends A

You can define a constructor in B that takes an object of A. This way we can do the "cast" e.g.:

public B(A a) {
    super(a.arg1, a.arg2); //arg1 and arg2 must be, at least, protected in class A
    // If B class has more attributes, then you would initilize them here
}

<input type='text' minlength=3 /><br />

if browser supports html5,

it will automatical be validate attributes(minlength) in tag

but Safari(iOS) doesn't working

You can also get stack trace as string via ExceptionUtils.getStackTrace.

See: ExceptionUtils.java

I use it only for log.debug, to keep log.error simple.

locals() returns a dictionary with local names:

def func(a,b,c):
    print(locals().keys())

prints the list of parameters. If you use other local variables those will be included in this list. But you could make a copy at the beginning of your function.

I was having the same problem. When I initially created the java project in Eclipse I specified JRE 8. When I went into the project's build path and edited the JRE System Library, the Java 8 execution environment was selected. When I chose to use an "Alernate JRE" (still java 8) it fixed the error for me.

"There are no safe means of assigning multiple recipients to a single mailto: link via HTML. There are safe, non-HTML, ways of assigning multiple recipients from a mailto: link."

http://www.sightspecific.com/~mosh/www_faq/multrec.html

For a quick fix to your problem, change your ; to a comma , and eliminate the spaces between email addresses

<a href='mailto:[email protected],[email protected]'>Email Us</a>

Tried and tested. It's as simple as follows:

string line = File.ReadLines(filePath).ElementAt(actualLineNumber - 1);

As long as you have a text file, this should work. Later, depending upon what data you expect to read, you can cast the string accordingly and use it.

The error log is straightforward. As it suggested,You need to add 198.211.99.20 to your ALLOWED_HOSTS setting.

In your project settings.py file,set ALLOWED_HOSTS like this :

ALLOWED_HOSTS = ['198.211.99.20', 'localhost', '127.0.0.1']

The way we usually use import is based on relative path.

. and .. are similar to how we use to navigate in terminal like cd .. to go out of directory and mv ~/file . to move a file to current directory.

my-app/
  node_modules/
  package.json
  src/
    containers/card.js
    components/header.js
    App.js
    index.js

In your case, App.js is in src/ directory while header.js is in src/components. To import you would do import Header from './components/header'. This roughly translate to in my current directory, find the components folder that contain a header file.

Now, if from header.js, you need to import something from card, you would do this. import Card from '../containers/card'. This translate to, move out of my current directory, look for a folder name containers that have a card file.

As for import React, { Component } from 'react', this does not start with a ./ or ../ or / therefore node will start looking for the module in the node_modules in a specific order till react is found. For a more detail understanding, it can be read here.

public class SQLCon
{
  public static string cs = 
   ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
}
protected void Page_Load(object sender, EventArgs e)
{
    SqlDataAdapter MyDataAdapter;
    SQLCon cs = new SQLCon();
    DataSet RsUser = new DataSet();
    RsUser = new DataSet();
    using (SqlConnection MyConnection = new SqlConnection(SQLCon.cs))
       {
        MyConnection.Open();
        MyDataAdapter = new SqlDataAdapter("GetAPPID", MyConnection);
        //'Set the command type as StoredProcedure.
        MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure;
        RsUser = new DataSet();
        MyDataAdapter.SelectCommand.Parameters.Add(new SqlParameter("@organizationID", 
        SqlDbType.Int));
        MyDataAdapter.SelectCommand.Parameters["@organizationID"].Value = TxtID.Text;
        MyDataAdapter.Fill(RsUser, "GetAPPID");
       }

      if (RsUser.Tables[0].Rows.Count > 0) //data was found
      {
        Session["AppID"] = RsUser.Tables[0].Rows[0]["AppID"].ToString();
       }
     else
       {

       }    
}    

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

I think you'll need to be a bit more specific for us to help you.

1. How are you finding this? Javascript? PHP? Perl?
2. Can you apply an ID attribute to the tag?

If the text is unique (or really, if it's not, but you'd have to run through an array) you could run a regular expression to find it. Using PHP's preg_match() would work for that.

If you're using Javascript and can insert an ID attribute, then you can use getElementById('id'). You can then access the returned element's attributes through the DOM: https://developer.mozilla.org/en/DOM/element.1.

This what I am using for MD5 hashes:

public static String getMD5(String filename)
        throws NoSuchAlgorithmException, IOException {
    MessageDigest messageDigest = 
        java.security.MessageDigest.getInstance("MD5");

    InputStream in = new FileInputStream(filename);

    byte [] buffer = new byte[8192];
    int len = in.read(buffer, 0, buffer.length);

    while (len > 0) {
        messageDigest.update(buffer, 0, len);
        len = in.read(buffer, 0, buffer.length);
    }
    in.close();

    return new BigInteger(1, messageDigest.digest()).toString(16);
}

EDIT: I've tested and I've noticed that with this also trailing zeros are cut. But this can only happen in the beginning, so you can compare with the expected length and pad accordingly.

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

This code was adapted from Ozgrid

and as jkf points out, from Mr Excel

Another option is the android-wheel project that comes pretty close the the UIDatePicker dialog of iOS.

It provides a vertical slider to pick anything(including date and time). If you prefer horizontal slider, the DateSlider referenced by Rabi is better.

If you're on a browser that supports it you can use CSS to transform the <a> into a table row:

.table-row { display: table-row; }
.table-cell { display: table-cell; }

<div style="display: table;">
    <a href="..." class="table-row">
        <span class="table-cell">This is a TD... ish...</span>
    </a>
</div>

Of course, you're limited to not putting block elements inside the <a>. You also can't mix this in with a regular <table>

How about

<input type="text" pattern="[789][0-9]{9}">

Use Json class instead of Content as shown following:

    //  When I want to return an error:
    if (!isFileSupported)
    {
        Response.StatusCode = (int) HttpStatusCode.BadRequest;
        return Json("The attached file is not supported", MediaTypeNames.Text.Plain);
    }
    else
    {
        //  When I want to return sucess:
        Response.StatusCode = (int)HttpStatusCode.OK; 
        return Json("Message sent!", MediaTypeNames.Text.Plain);
    }

Also set contentType:

contentType: 'application/json; charset=utf-8',

Here is another example that return's a boolean value using try/catch.

private boolean doSomeThing(int index){
    try {
        if(index%2==0) 
            return true; 
    } catch (Exception e) {
        System.out.println(e.getMessage()); 
    }finally {
        System.out.println("Finally!!! ;) ");
    }
    return false; 
}

I don't have MySQL, but there are RDBMS (Postgres, among others) in which you can use the hack

SELECT id || '' FROM some_table;

The concatenate does an implicit conversion.

The venerable DateJS library has a formatting routine (it overrides ".toString()"). You could also do one yourself pretty easily because the "Date" methods give you all the numbers you need.

2017:

Simple way, adding time color to the message, you don't need to change your code, use keep your console.log('msg') or console.err('error')

var clc = require("cli-color");
var mapping = {
  log: clc.blue,
  warn: clc.yellow,
  error: clc.red
};

["log", "warn", "error"].forEach(function(method) {
  var oldMethod = console[method].bind(console);
  console[method] = function() {
    oldMethod.apply(
      console,
      [mapping[method](new Date().toISOString())]
      .concat(arguments)
    );
  };
});

Try:

> d <- data.frame(a=1:3, b=4:6, c=7:9)

> d
  a b c
1 1 4 7
2 2 5 8
3 3 6 9

> d[1, ]
  a b c
1 1 4 7

> d[1, ]['a']
  a
1 1

Just adding another way for DataFrame expanded over all columns:

for column in df.columns:
   df = df[df[column]!=0]

Example:

def z_score(data,count):
   threshold=3
   for column in data.columns:
       mean = np.mean(data[column])
       std = np.std(data[column])
       for i in data[column]:
           zscore = (i-mean)/std
           if(np.abs(zscore)>threshold):
               count=count+1
               data = data[data[column]!=i]
   return data,count

This tool is working very well right now.
