Programs & Examples On #Gae quotas

Ok, Im assuming you want to put the .left inside the container so I suggest you edit your html. The key is the position:absolute and right:0

#right { 
    background-color: red;
    height: 300px;
    width: 300px;
    z-index: 999999;
    margin-top: 0px;
    position: absolute;
    right:0;
}

here is the full code: http://jsfiddle.net/T9FJL/

Using sed:

$ echo '1:2:3:4:5' | sed 's/.*://' # => 5

$ echo '' | sed 's/.*://' # => (empty)

$ echo ':' | sed 's/.*://' # => (empty)
$ echo ':b' | sed 's/.*://' # => b
$ echo '::c' | sed 's/.*://' # => c

$ echo 'a' | sed 's/.*://' # => a
$ echo 'a:' | sed 's/.*://' # => (empty)
$ echo 'a:b' | sed 's/.*://' # => b
$ echo 'a::c' | sed 's/.*://' # => c

I guess I came a little late for this but I think the main problem here is that you're patching datetime.date.today directly and, according to the documentation, this is wrong.

You should patch the reference imported in the file where the tested function is, for example.

Let's say you have a functions.py file where you have the following:

import datetime

def get_today():
    return datetime.date.today()

then, in your test, you should have something like this

import datetime
import unittest

from functions import get_today
from mock import patch, Mock

class GetTodayTest(unittest.TestCase):

    @patch('functions.datetime')
    def test_get_today(self, datetime_mock):
        datetime_mock.date.today = Mock(return_value=datetime.strptime('Jun 1 2005', '%b %d %Y'))
        value = get_today()
        # then assert your thing...

Hope this helps a little bit.

Along with Environment.NewLine and the literal \r\n or just \n you may also use a verbatim string in C#. These begin with @ and can have embedded newlines. The only thing to keep in mind is that " needs to be escaped as "". An example:

string s = @"This is a string
that contains embedded new lines,
that will appear when this string is used."

Although @serge answer is correct but i compared time consumption of his way against xmlpath and i found the xmlpath is so faster. I'll write the compare code and you can check it by yourself. This is @serge way:

DECLARE @startTime datetime2;
DECLARE @endTime datetime2;
DECLARE @counter INT;
SET @counter = 1;

set nocount on;

declare @YourTable table (ID int, Name nvarchar(50))

WHILE @counter < 1000
BEGIN
    insert into @YourTable VALUES (ROUND(@counter/10,0), CONVERT(NVARCHAR(50), @counter) + 'CC')
    SET @counter = @counter + 1;
END

SET @startTime = GETDATE()

;WITH Partitioned AS
(
    SELECT 
        ID,
        Name,
        ROW_NUMBER() OVER (PARTITION BY ID ORDER BY Name) AS NameNumber,
        COUNT(*) OVER (PARTITION BY ID) AS NameCount
    FROM @YourTable
),
Concatenated AS
(
    SELECT ID, CAST(Name AS nvarchar) AS FullName, Name, NameNumber, NameCount FROM Partitioned WHERE NameNumber = 1

    UNION ALL

    SELECT 
        P.ID, CAST(C.FullName + ', ' + P.Name AS nvarchar), P.Name, P.NameNumber, P.NameCount
    FROM Partitioned AS P
        INNER JOIN Concatenated AS C ON P.ID = C.ID AND P.NameNumber = C.NameNumber + 1
)
SELECT 
    ID,
    FullName
FROM Concatenated
WHERE NameNumber = NameCount

SET @endTime = GETDATE();

SELECT DATEDIFF(millisecond,@startTime, @endTime)
--Take about 54 milliseconds

And this is xmlpath way:

DECLARE @startTime datetime2;
DECLARE @endTime datetime2;
DECLARE @counter INT;
SET @counter = 1;

set nocount on;

declare @YourTable table (RowID int, HeaderValue int, ChildValue varchar(5))

WHILE @counter < 1000
BEGIN
    insert into @YourTable VALUES (@counter, ROUND(@counter/10,0), CONVERT(NVARCHAR(50), @counter) + 'CC')
    SET @counter = @counter + 1;
END

SET @startTime = GETDATE();

set nocount off
SELECT
    t1.HeaderValue
        ,STUFF(
                   (SELECT
                        ', ' + t2.ChildValue
                        FROM @YourTable t2
                        WHERE t1.HeaderValue=t2.HeaderValue
                        ORDER BY t2.ChildValue
                        FOR XML PATH(''), TYPE
                   ).value('.','varchar(max)')
                   ,1,2, ''
              ) AS ChildValues
    FROM @YourTable t1
    GROUP BY t1.HeaderValue

SET @endTime = GETDATE();

SELECT DATEDIFF(millisecond,@startTime, @endTime)
--Take about 4 milliseconds

In /etc/apache2/ports.conf, change the port as

Listen 8079

Then go to /etc/apache2/sites-enabled/000-default.conf

And change the first line as

<VirtualHost *: 8079>

Now restart

sudo service apache2 restart

Apache will now listen on port 8079 and redirect to /var/www/html

I just got the same situation, Factory data reset worked well for me.

You can use a free third party solution to handle this for you such as Quantum-Key.Net It's free and handles payments via paypal through a web sales page it creates for you, key issuing via email and locks key use to a specific computer to prevent piracy.

Your should also take care to obfuscate/encrypt your code or it can easily be reverse engineered using software such as De4dot and .NetReflector. A good free code obfuscator is ConfuserEx wich is fast and simple to use and more effective than expensive alternatives.

You should run your finished software through De4Dot and .NetReflector to reverse-engineer it and see what a cracker would see if they did the same thing and to make sure you have not left any important code exposed or undisguised.

Your software will still be crackable but for the casual cracker it may well be enough to put them off and these simple steps will also prevent your code being extracted and re-used.

1. Find the playlist/manifest with the developer tools network tab. There is always one, as that's how it works. It might have a m3u8 extension that you can type into the Filter. (The youtube-dl tool can also find the m3u8 tool automatically some time give it direct link to the webpage where the video is being displayed.)

2. Give it to the youtube-dl tool (Download) . It can download much more than just YouTube. It'll auto-download each segment then combine everything with FFmpeg then discard the parts. There is a good chance it supports the site you want to download from natively, and you don't even need to do step #1.

3. If you find a site that is stubborn and you run into 403 errors... Telerik Fiddler to the rescue. It can catch and save anything transmitted (such as the video file) as it acts as a local proxy. Everything you see/hear can be downloaded, unless it's DRM content like Spotify.

Note: in windows, you can use youtube-dl.exe using "Command Prompt" or creating a batch file. i.e

d:\youtube-dl.exe https://www.youtube.com/watch?v=gbdFOwKHil0

Just delete the .lock file in the .metadata directory in your eclipse workspace directory.

Precaution - If you delete the .metadata folder all preference will be deleted.

Another solution would be as below where the list is placed under a drop-down button.

  <button class="btn dropdown-toggle btn-primary btn-sm" data-toggle="dropdown"
    >Markets<span class="caret"></span></button>

    <ul class="dropdown-menu", style="height:40%; overflow:hidden; overflow-y:scroll;">
      {{ form.markets }}
    </ul>

SHA is a family of "Secure Hash Algorithms" that have been developed by the National Security Agency. There is currently a competition among dozens of options for who will become SHA-3, the new hash algorithm for 2012+.

You use SHA functions to take a large document and compute a "digest" (also called "hash") of the input. It's important to realize that this is a one-way process. You can't take a digest and recover the original document.

AES, the Advanced Encryption Standard is a symmetric block algorithm. This means that it takes 16 byte blocks and encrypts them. It is "symmetric" because the key allows for both encryption and decryption.

UPDATE: Keccak was named the SHA-3 winner on October 2, 2012.

I tested this code on Nougat emulator and it worked:

In manifest add:

<application...

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths"/>
    </provider>
</application>

Create empty xml folder in res folder and past in the provider_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
 <paths xmlns:android="http://schemas.android.com/apk/res/android">
   <external-path name="external_files" path="."/>
  </paths>

Then put the next snippet into your code (for instance fragment):

File photoLcl = new File(homeDirectory + "/" + fileNameLcl);
Uri imageUriLcl = FileProvider.getUriForFile(getActivity(), 
  getActivity().getApplicationContext().getPackageName() +
    ".provider", photoLcl);
ContentResolver contentResolver = getActivity().getContentResolver();
contentResolver.delete(imageUriLcl, null, null);

This can be done using ServerSocket, same as on JavaSE. This class is available on Android. android.permission.INTERNET is required.

The only more tricky part, you need a separate thread wait on the ServerSocket, servicing sub-sockets that come from its accept method. You also need to stop and resume this thread as needed. The simplest approach seems to kill the waiting thread by closing the ServerSocket. If you only need a server while your activity is on the top, starting and stopping ServerSocket thread can be rather elegantly tied to the activity life cycle methods. Also, if the server has multiple users, it may be good to service requests in the forked threads. If there is only one user, this may not be necessary.

If you need to tell the user on which IP is the server listening,use NetworkInterface.getNetworkInterfaces(), this question may tell extra tricks.

Finally, here there is possibly the complete minimal Android server that is very short, simple and may be easier to understand than finished end user applications, recommended in other answers.

Java class final and method final -> sealed. Java member variable final -> readonly for runtime constant, const for compile time constant.

No equivalent for Local Variable final and method argument final

your id attribute is not set. this MAY be due to the fact that the DB field is not set to auto increment? what DB are you using? MySQL? is your field set to AUTO INCREMENT?

You can

1. create a table variable to hold the result set from the stored proc and then
2. insert the output of the stored proc into the table variable, and then
3. use the table variable exactly as you would any other table...

... sql ....

Declare @T Table ([column definitions here])
Insert @T Exec storedProcname params 
Select * from @T Where ...

Use Simple HTML

<frameset cols="25%,*">
  <frame src="frame_a.htm">
  <frame src="frame_b.htm">
</frameset>

The solution I use for large sql restore is a mysqldumpsplitter script. I split my sql.gz into individual tables. then load up something like mysql workbench and process it as a restore to the desired schema.

Here is the script https://github.com/kedarvj/mysqldumpsplitter

And this works for larger sql restores, my average on one site I work with is a 2.5gb sql.gz file, 20GB uncompressed, and ~100Gb once restored fully

# Copy the certificate into the directory Java_home\Jre\Lib\Security

changeit is the default truststore password

If you wish to get difference in wall clock time, for local timezone and with day-light saving awareness.

Date.prototype.diffDays = function (date: Date): number {

    var utcThis = Date.UTC(this.getFullYear(), this.getMonth(), this.getDate(), this.getHours(), this.getMinutes(), this.getSeconds(), this.getMilliseconds());
    var utcOther = Date.UTC(date.getFullYear(), date.getMonth(), date.getDate(), date.getHours(), date.getMinutes(), date.getSeconds(), date.getMilliseconds());

    return (utcThis - utcOther) / 86400000;
};

Test

it('diffDays - Czech DST', function () {
    // expect this to parse as local time
    // with Czech calendar DST change happened 2012-03-25 02:00
    var pre = new Date('2012/03/24 03:04:05');
    var post = new Date('2012/03/27 03:04:05');

    // regardless DST, you still wish to see 3 days
    expect(pre.diffDays(post)).toEqual(-3);
});

Diff minutes or seconds is in same fashion.

You need a more specific expression. Try grep " OK$" or grep "[0-9]* OK". You want to choose a pattern that matches what you want, but won't match what you don't want. That pattern will depend upon what your whole file contents might look like.

You can also do: grep -w "OK" which will only match a whole word "OK", such as "1 OK" but won't match "1OK" or "OKFINE".

$ cat test.txt | grep -w "OK"
1 OK
2 OK
4 OK

IMHO best way how to do it these days:

Suppose you have a Collection "dups" and you want to create another Collection containing the same elements but with all duplicates eliminated. The following one-liner does the trick.

Collection<collectionType> noDups = new HashSet<collectionType>(dups);

It works by creating a Set which, by definition, cannot contain duplicates.

Based on oracle doc.

By converting the matrix to array by using

n12 = np.squeeze(np.asarray(n2))

X12 = np.squeeze(np.asarray(x1))

solved the issue.

The EntityManager.flush() operation can be used the write all changes to the database before the transaction is committed. By default JPA does not normally write changes to the database until the transaction is committed. This is normally desirable as it avoids database access, resources and locks until required. It also allows database writes to be ordered, and batched for optimal database access, and to maintain integrity constraints and avoid deadlocks. This means that when you call persist, merge, or remove the database DML INSERT, UPDATE, DELETE is not executed, until commit, or until a flush is triggered.

In case you get a cross-domain error:

If you have control over the content of the iframe - that is, if it is merely loaded in a cross-origin setup such as on Amazon Mechanical Turk - you can circumvent this problem with the <body onload='my_func(my_arg)'> attribute for the inner html.

For example, for the inner html, use the this html parameter (yes - this is defined and it refers to the parent window of the inner body element):

<body onload='changeForm(this)'>

In the inner html :

    function changeForm(window) {
        console.log('inner window loaded: do whatever you want with the inner html');
        window.document.getElementById('mturk_form').style.display = 'none';

Whenever you do a basic web search for random number generation in the C++ programming language this question is usually the first to pop up! I want to throw my hat into the ring to hopefully better clarify the concept of pseudo-random number generation in C++ for future coders that will inevitably search this same question on the web!

The Basics

Pseudo-random number generation involves the process of utilizing a deterministic algorithm that produces a sequence of numbers whose properties approximately resemble random numbers. I say approximately resemble, because true randomness is a rather elusive mystery in mathematics and computer science. Hence, why the term pseudo-random is utilized to be more pedantically correct!

Before you can actually use a PRNG, i.e., pseudo-random number generator, you must provide the algorithm with an initial value often referred too as the seed. However, the seed must only be set once before using the algorithm itself!

/// Proper way!
seed( 1234 ) /// Seed set only once...
for( x in range( 0, 10) ):
  PRNG( seed ) /// Will work as expected

/// Wrong way!
for( x in rang( 0, 10 ) ):
  seed( 1234 ) /// Seed reset for ten iterations!
  PRNG( seed ) /// Output will be the same...

Thus, if you want a good sequence of numbers, then you must provide an ample seed to the PRNG!

The Old C Way

The backwards compatible standard library of C that C++ has, uses what is called a linear congruential generator found in the cstdlib header file! This PRNG functions through a discontinuous piecewise function that utilizes modular arithmetic, i.e., a quick algorithm that likes to use the modulo operator '%'. The following is common usage of this PRNG, with regards to the original question asked by @Predictability:

#include <iostream>
#include <cstdlib>
#include <ctime>

int main( void )
{
  int low_dist  = 1;
  int high_dist = 6;
  std::srand( ( unsigned int )std::time( nullptr ) );
  for( int repetition = 0; repetition < 10; ++repetition )
    std::cout << low_dist + std::rand() % ( high_dist - low_dist ) << std::endl;
  return 0;
}

The common usage of C's PRNG houses a whole host of issues such as:

1. The overall interface of std::rand() isn't very intuitive for the proper generation of pseudo-random numbers between a given range, e.g., producing numbers between [1, 6] the way @Predictability wanted.
2. The common usage of std::rand() eliminates the possibility of a uniform distribution of pseudo-random numbers, because of the Pigeonhole Principle.
3. The common way std::rand() gets seeded through std::srand( ( unsigned int )std::time( nullptr ) ) technically isn't correct, because time_t is considered to be a restricted type. Therefore, the conversion from time_t to unsigned int is not guaranteed!

For more detailed information about the overall issues of using C's PRNG, and how to possibly circumvent them, please refer to Using rand() (C/C++): Advice for the C standard library’s rand() function!

The Standard C++ Way

Since the ISO/IEC 14882:2011 standard was published, i.e., C++11, the random library has been apart of the C++ programming language for a while now. This library comes equipped with multiple PRNGs, and different distribution types such as: uniform distribution, normal distribution, binomial distribution, etc. The following source code example demonstrates a very basic usage of the random library, with regards to @Predictability's original question:

#include <iostream>
#include <cctype>
#include <random>

using u32    = uint_least32_t; 
using engine = std::mt19937;

int main( void )
{
  std::random_device os_seed;
  const u32 seed = os_seed();

  engine generator( seed );
  std::uniform_int_distribution< u32 > distribute( 1, 6 );

  for( int repetition = 0; repetition < 10; ++repetition )
    std::cout << distribute( generator ) << std::endl;
  return 0;
}

The 32-bit Mersenne Twister engine, with a uniform distribution of integer values was utilized in the above example. (The name of the engine in source code sounds weird, because its name comes from its period of 2^19937-1 ). The example also uses std::random_device to seed the engine, which obtains its value from the operating system (If you are using a Linux system, then std::random_device returns a value from /dev/urandom).

Take note, that you do not have to use std::random_device to seed any engine. You can use constants or even the chrono library! You also don't have to use the 32-bit version of the std::mt19937 engine, there are other options! For more information about the capabilities of the random library, please refer to cplusplus.com

All in all, C++ programmers should not use std::rand() anymore, not because its bad, but because the current standard provides better alternatives that are more straight forward and reliable. Hopefully, many of you find this helpful, especially those of you who recently web searched generating random numbers in c++!

To find a compiler, you'll have 1 per .net version installed, type in a command prompt.

dir c:\Windows\Microsoft.NET\vbc.exe /a/s

Windows Forms

For a Windows Forms version (no console window and we don't get around to actually creating any forms - though you can if you want).

Compile line in a command prompt.

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\vbc.exe" /t:winexe "%userprofile%\desktop\VBS2Exe.vb"

Text for VBS2EXE.vb

Imports System.Windows.Forms 

Partial Class MyForm : Inherits Form 

Private Sub InitializeComponent() 


End Sub

Public Sub New() 

InitializeComponent() 

End Sub

Public Shared Sub Main() 

Dim sc as object 
Dim Scrpt as string

sc = createObject("MSScriptControl.ScriptControl")

Scrpt = "msgbox " & chr(34) & "Hi there I'm a form" & chr(34)

With SC 
.Language = "VBScript" 
.UseSafeSubset = False 
.AllowUI = True 
End With


sc.addcode(Scrpt)


End Sub

End Class

Using these optional parameters gives you an icon and manifest. A manifest allows you to specify run as normal, run elevated if admin, only run elevated.

/win32icon: Specifies a Win32 icon file (.ico) for the default Win32 resources.

/win32manifest: The provided file is embedded in the manifest section of the output PE.

In theory, I have UAC off so can't test, but put this text file on the desktop and call it vbs2exe.manifest, save as UTF-8.

The command line

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\vbc.exe" /t:winexe /win32manifest:"%userprofile%\desktop\VBS2Exe.manifest" "%userprofile%\desktop\VBS2Exe.vb"

The manifest

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
  <assembly xmlns="urn:schemas-microsoft-com:asm.v1" 
  manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" 
  processorArchitecture="*" name="VBS2EXE" type="win32" /> 
  <description>Script to Exe</description> 
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> 
  <security> <requestedPrivileges> 
  <requestedExecutionLevel level="requireAdministrator" 
  uiAccess="false" /> </requestedPrivileges> 
  </security> </trustInfo> </assembly>

Hopefully it will now ONLY run as admin.

Give Access To a Host's Objects

Here's an example giving the vbscript access to a .NET object.

Imports System.Windows.Forms 

Partial Class MyForm : Inherits Form 

Private Sub InitializeComponent() 


End Sub 

Public Sub New() 

InitializeComponent() 

End Sub 

Public Shared Sub Main() 

Dim sc as object
Dim Scrpt as string 

sc = createObject("MSScriptControl.ScriptControl") 

Scrpt = "msgbox " & chr(34) & "Hi there I'm a form" & chr(34) & ":msgbox meScript.state" 

With SC
.Language = "VBScript"
.UseSafeSubset = False
.AllowUI = True
.addobject("meScript", SC, true)
End With 


sc.addcode(Scrpt) 


End Sub 

End Class

Download vbs2exe.res file from https://skydrive.live.com/redir?resid=E2F0CE17A268A4FA!121 and put on desktop.

Download ResHacker from http://www.angusj.com/resourcehacker

Open vbs2exe.res file in ResHacker. Edit away. Click Compile button. Click File menu - Save.

Type

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\vbc.exe" /t:winexe /win32manifest:"%userprofile%\desktop\VBS2Exe.manifest" /win32resource:"%userprofile%\desktop\VBS2Exe.res" "%userprofile%\desktop\VBS2Exe.vb"

This works:

<div>
    <input type="text" 
        style="margin: 5px; padding: 4px; border: 1px solid; 
        width: 200px; width: calc(100% - 20px);">
</div>

The first 'width' is a fallback rule for older browsers.

Please see http://mvnrepository.com/artifact/javax.mail/mail/, you can download jar or use the maven dependency, depending on your project type. That should pretty much cover it and you won't get a NoClassDefFoundError exception.

I wanted something pretty close to this - the moment a user picks an item, even by just hitting the arrow keys to one (focus), I want that data item attached to the tag in question. When they type again without picking another item, I want that data cleared.

(function() {
    var lastText = '';

    $('#MyTextBox'), {
        source: MyData
    })
    .on('autocompleteselect autocompletefocus', function(ev, ui) {
        lastText = ui.item.label;
        jqTag.data('autocomplete-item', ui.item);
    })
    .keyup(function(ev) {
        if (lastText != jqTag.val()) {
            // Clear when they stop typing
            jqTag.data('autocomplete-item', null);

            // Pass the event on as autocompleteclear so callers can listen for select/clear
            var clearEv = $.extend({}, ev, { type: 'autocompleteclear' });
            return jqTag.trigger(clearEv);
    });
})();

With this in place, 'autocompleteselect' and 'autocompletefocus' still fire right when you expect, but the full data item that was selected is always available right on the tag as a result. 'autocompleteclear' now fires when that selection is cleared, generally by typing something else.

I used this code:

ws.Range("A:A").FormulaR1C1 = "=DATEVALUE(RC[1])"

column A will be mm/dd/yyyy

RC[1] is column B, the TEXT string, eg, 01/30/12, THIS IS NOT DATE TYPE

You forgot the HTTP part:

window.location.href = "http://example.com/Registration/Success/";

If you're using Jquery to manipulate the DOM, then I have found the following a good way to include logic in a Jquery statement:

$(selector).addClass(A && B?'classIfTrue':'');

A JRE doesn't have a tools.jar, you need a JDK. Set your JAVA_HOME and PATH variables so that they point to a JDK, not a JRE.

Notepad++ only has column editing. This is not completely the same as multiple cursors.

Sublime Text has a marvelous implementation of this, might be worth checking out...
It's a relatively new editor (2011) that is gaining popularity quite fast: http://www.google.com/trends/explore#q=Notepad%2B%2B%2C%20Sublime%20Text&cmpt=q

Edit: Apparently somewhere around Notepad++ version 6.x multi-cursor editing got added, but there are still a few more advanced features for it in Sublime, like "select next occurrence".

Here is your code. I'm assuming you're using python 3 based on the your use of print() and input():

import random

def main():
    #random.seed() --> don't need random.seed()

    #Prompts the user to enter the number of tickets they wish to play.

    #python 3 version:
    tickets = int(input("How many lottery tickets do you want?\n"))

    #Creates the dictionaries "winning_numbers" and "guess." Also creates the variable "winnings" for total amount of money won.
    winning_numbers = []
    winnings = 0

    #Generates the winning lotto numbers.
    for i in range(tickets * 5):
        #del winning_numbers[:] what is this line for?
        randNum = random.randint(1,30)
        while randNum in winning_numbers:    
            randNum = random.randint(1,30)
        winning_numbers.append(randNum)

    print(winning_numbers)
    guess = getguess(tickets)
    nummatches = checkmatch(winning_numbers, guess)

    print("Ticket #"+str(i+1)+": The winning combination was",winning_numbers,".You matched",nummatches,"number(s).\n")

    winningRanks = [0, 0, 10, 500, 20000, 1000000]

    winnings = sum(winningRanks[:nummatches + 1])

    print("You won a total of",winnings,"with",tickets,"tickets.\n")


#Gets the guess from the user.
def getguess(tickets):
    guess = []
    for i in range(tickets):
        bubble = [int(i) for i in input("What numbers do you want to choose for ticket #"+str(i+1)+"?\n").split()]
        guess.extend(bubble)
        print(bubble)
    return guess

#Checks the user's guesses with the winning numbers.
def checkmatch(winning_numbers, guess):
    match = 0
    for i in range(5):
        if guess[i] == winning_numbers[i]:
            match += 1
    return match

main()

Placing @Transient on getter with private field worked for me.

private String name;

    @Transient
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

You want to convert mdb to mysql (direct transfer to mysql or mysql dump)?

Try a software called Access to MySQL.

Access to MySQL is a small program that will convert Microsoft Access Databases to MySQL.

• Wizard interface.
• Transfer data directly from one server to another.
• Create a dump file.
• Select tables to transfer.
• Select fields to transfer.
• Transfer password protected databases.
• Supports both shared security and user-level security.
• Optional transfer of indexes.
• Optional transfer of records.
• Optional transfer of default values in field definitions.
• Identifies and transfers auto number field types.
• Command line interface.
• Easy install, uninstall and upgrade.

See the aforementioned link for a step-by-step tutorial with screenshots.

I usually do this in my CSV files parsing routines. Assume that 'line' variable is one line within a CSV file and all of the columns' values are enclosed in double quotes. After the below two lines execute, you will get CSV columns in the 'values' collection.

// The below two lines will split the columns as well as trim the DBOULE QUOTES around values but NOT within them
    string trimmedLine = line.Trim(new char[] { '\"' });
    List<string> values = trimmedLine.Split(new string[] { "\",\"" }, StringSplitOptions.None).ToList();

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

EDIT: Consider looking at and upvoting Malvineous's answer on this page. Netmasks are a much more elegant solution.

Simply use a percent sign as a wildcard in the IP address.

From http://dev.mysql.com/doc/refman/5.1/en/grant.html

You can specify wildcards in the host name. For example, user_name@'%.example.com' applies to user_name for any host in the example.com domain, and user_name@'192.168.1.%' applies to user_name for any host in the 192.168.1 class C subnet.

If you have an Array of strings, you can also initialize it like this:

array = %w{1 2 3}

just separate each element with any whitespace

You need to use bool query with must/must_not and exists

To get where place is null

{
  "query": {
    "bool": {
      "must_not": {
        "exists": {
          "field": "place"
        }
      }
    }
  }
}

To get where place is not null

{
  "query": {
    "bool": {
      "must": {
        "exists": {
          "field": "place"
        }
      }
    }
  }
}

Specify the Class Card for the constructor-:

void Card::Card(Card::Rank rank, Card::Suit suit) {

And also define the default constructor and destructor.

Why use a regex?

name.contains(" ")

That should work just as well, and be faster.

Here is an example

private void doOpenFile() {
    int result = myFileChooser.showOpenDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        Path path = myFileChooser.getSelectedFile().toPath();

        try {
            String contentString = "";

            for (String s : Files.readAllLines(path, StandardCharsets.UTF_8)) {
                contentString += s;
            }

            jText.setText(contentString);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

private void doSaveFile() {
    int result = myFileChooser.showSaveDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        // We'll be making a mytmp.txt file, write in there, then move it to
        // the selected
        // file. This takes care of clearing that file, should there be
        // content in it.
        File targetFile = myFileChooser.getSelectedFile();

        try {
            if (!targetFile.exists()) {
                targetFile.createNewFile();
            }

            FileWriter fw = new FileWriter(targetFile);

            fw.write(jText.getText());
            fw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

The idea that you need to get the reference to the object that is contained inside a Set object is common. It can be archived by 2 ways:

1. Use HashSet as you wanted, then:

   public Object getObjectReference(HashSet<Xobject> set, Xobject obj) {
       if (set.contains(obj)) {
           for (Xobject o : set) {
               if (obj.equals(o))
                   return o;
           }
       }
       return null;
   }
   

For this approach to work, you need to override both hashCode() and equals(Object o) methods In the worst scenario we have O(n)

2. Second approach is to use TreeSet

   public Object getObjectReference(TreeSet<Xobject> set, Xobject obj) {
       if (set.contains(obj)) {
           return set.floor(obj);
       }
       return null;
   }
   

This approach gives O(log(n)), more efficient. You don't need to override hashCode for this approach but you have to implement Comparable interface. ( define function compareTo(Object o)).

#define PADDING 5

@interface MyLabel : UILabel

@end

    return [super drawTextInRect:UIEdgeInsetsInsetRect(rect, UIEdgeInsetsMake(0, PADDING, 0, PADDING))];
}

    return CGRectInset([self.attributedText boundingRectWithSize:CGSizeMake(999, 999)

                                                         context:nil], -PADDING, 0);
}

This feature is in pre-release now and works with Visual Studio 2015.

For example:

[TestClass]
public class UnitTest1
{
    [TestMethod]
    [DataRow(1, 2, 2)]
    [DataRow(2, 3, 5)]
    [DataRow(3, 5, 8)]
    public void AdditionTest(int a, int b, int result)
    {
        Assert.AreEqual(result, a + b);
    }
}

Most likely you're looking for the ToCharArray() method. However, you will need to do slightly more work if a string[] is required, as you noted in your post.

    string str = "this is a test.";
    char[] charArray = str.ToCharArray();
    string[] strArray = str.Select(x => x.ToString()).ToArray();

Edit: If you're worried about the conciseness of the conversion, I suggest you make it into an extension method.

public static class StringExtensions
{
    public static string[] ToStringArray(this string s)
    {
        if (string.IsNullOrEmpty(s))
            return null;

        return s.Select(x => x.ToString()).ToArray();
    }
} 

fyi, this can happen if you are using the html type="number" attribute on your input tag. Entering a non-number will clear it before your script knows what's going on.

JDK 1.8 have some more enrich feature which doesn't support to many eclipse .

If you didn't find java compliance level as 1.8 in java compiler ,then go ahead and install the below eclipse 32bit or 64 bit depending on your system supports.

1. Install jdk 1.8 and then set the JAVA_HOME and CLASSPATH in environment variable.
2. Download eclipse-jee-neon-3-win32 and unzip : supports to java 1.8
3. Or download Oracle Enterprise Pack for Eclipse (12.2.1.5) and unzip :Supports java 1.8 with 64 bit OS
4. Right click your project > properties
5. Select “Java Compiler” on left and set java compliance level to 1.8 [select from the dropdown 1.8]

6. Try running one java program supports to java 8 like lambda expression as below and if no compilation error ,means your eclipse supports to java 1.8, something like this:

   interface testI{
       void show();
   }
   
   /*class A implements testI{
       public void show(){
           System.out.println("Hello");
       }
   }*/
   
   public class LambdaDemo1 {
       public static void main(String[] args) {
           testI test ;
           /*test= new A();
           test.show();*/
           test = () ->System.out.println("Hello,how are you?"); //lambda 
           test.show();
       }        
   }
   

I have solved this problem. You only need to refer to someone else's readme file.

At first,you should upload an image file to github code library ! Then direct reference to the address of the image file .

If they're both strings you can just do:

#define STR3 STR1 STR2

This then expands to:

#define STR3 "s" "1"

and in the C language, separating two strings with space as in "s" "1" is exactly equivalent to having a single string "s1".

Besides de color, my problem was that I was setting the text using textlabel

bt.titleLabel?.text = title

and I solved changing to:

bt.setTitle(title, for: .normal)

: can also be for block comment (similar to /* */ in C language). For example, if you want to skip a block of code in your script, you can do this:

: << 'SKIP'

your code block here

SKIP

Can't pickle <type 'function'>: attribute lookup __builtin__.function failed

This error will also come if you have any inbuilt function inside the model object that was passed to the async job.

So make sure to check the model objects that are passed doesn't have inbuilt functions. (In our case we were using FieldTracker() function of django-model-utils inside the model to track a certain field). Here is the link to relevant GitHub issue.

For Sequelize 4

Query

SELECT * FROM Student WHERE LastName='Doe' 
AND (FirstName = "John" or FirstName = "Jane") AND Age BETWEEN 18 AND 24 

Syntax with Operators

const Op = require('Sequelize').Op;

var r = await to (Student.findAll(
{
  where: {
    LastName: "Doe",
    FirstName: {
      [Op.or]: ["John", "Jane"]
    },
    Age: {
      // [Op.gt]: 18
      [Op.between]: [18, 24]
    }
  }
}
));

Notes

• For better security Sequelize recommends dropping alias operators $ (e.g $and, $or ...)
• Unless you have {freezeTableName: true} set in the table model then Sequelize will query against the plural form of its name ( Student -> Students )

In SQL, this problem could be solved by several methods:

select * from df1 where exists (select * from df2 where df2.user_id = df1.user_id)
union all
select * from df2 where exists (select * from df1 where df1.user_id = df2.user_id)

or join and then unpivot (possible in SQL server)

select
    df1.user_id,
    c.rating
from df1
    inner join df2 on df2.user_i = df1.user_id
    outer apply (
        select df1.rating union all
        select df2.rating
    ) as c

Second one could be written in pandas with something like:

>>> df1 = pd.DataFrame({"user_id":[1,2,3], "rating":[10, 15, 20]})
>>> df2 = pd.DataFrame({"user_id":[3,4,5], "rating":[30, 35, 40]})
>>>
>>> df4 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df = pd.merge(df1, df2, on='user_id', suffixes=['_1', '_2'])
>>> df3 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df4 = df[['user_id', 'rating_2']].rename(columns={'rating_2':'rating'})
>>> pd.concat([df3, df4], axis=0)
   user_id  rating
0        3      20
0        3      30

I use java 1.8 with com.fasterxml.jackson.databind.ObjectMapper

ObjectMapper mapper = new ObjectMapper();
Integer      value = mapper.readValue(new URL("your url here"), Integer.class);

Integer.class can be also a complex type. Just for example used.

If the object you are trying to cast from or to has properties that are also user-defined classes, and you don't want to go through reflection, you can use this.

<?php
declare(strict_types=1);
namespace Your\Namespace\Here
{
  use Zend\Logger; // or your logging mechanism of choice
  final class OopFunctions
  {
    /**
     * @param object $from
     * @param object $to
     * @param Logger $logger
     *
     * @return object
     */
     static function Cast($from, $to, $logger)
    {
      $logger->debug($from);
      $fromSerialized = serialize($from);
      $fromName = get_class($from);
      $toName = get_class($to);
      $toSerialized = str_replace($fromName, $toName, $fromSerialized);
      $toSerialized = preg_replace("/O:\d*:\"([^\"]*)/", "O:" . strlen($toName) . ":\"$1", $toSerialized);
      $toSerialized = preg_replace_callback(
        "/s:\d*:\"[^\"]*\"/", 
        function ($matches)
        {
          $arr = explode(":", $matches[0]);
          $arr[1] = mb_strlen($arr[2]) - 2;
          return implode(":", $arr);
        }, 
        $toSerialized
      );
      $to = unserialize($toSerialized);
      $logger->debug($to);
      return $to;
    }
  }
}

Using PHP from the command line

Use " instead of ' on Windows when using the CLI version with -r:

php -r "echo 1;"

-- correct

php -r 'echo 1;'

-- incorrect

  PHP Parse error:  syntax error, unexpected ''echo' (T_ENCAPSED_AND_WHITESPACE), expecting end of file in Command line code on line 1

Don't forget the semicolon to close the line.

Summary:

• Object: A data structure in which data is stored as key value pairs. In an object the key has to be a number, string, or symbol. The value can be anything so also other objects, functions etc. A object is an non ordered data structure, i.e. the sequence of insertion of key value pairs is not remembered
• ES6 Map: A data structure in which data is stored as key value pairs. In which a unique key maps to a value. Both the key and the value can be in any data type. A map is a iterable data structure, this means that the sequence of insertion is remembered and that we can access the elements in e.g. a for..of loop

Key differences:

• A Map is ordered and iterable, whereas a objects is not ordered and not iterable

• We can put any type of data as a Map key, whereas objects can only have a number, string, or symbol as a key.

• A Map inherits from Map.prototype. This offers all sorts of utility functions and properties which makes working with Map objects a lot easier.

Example:

object:

let obj = {};_x000D_
_x000D_
// adding properties to a object_x000D_
obj.prop1 = 1;_x000D_
obj[2]    =  2;_x000D_
_x000D_
// getting nr of properties of the object_x000D_
console.log(Object.keys(obj).length)_x000D_
_x000D_
// deleting a property_x000D_
delete obj[2]_x000D_
_x000D_
console.log(obj)

Map:

const myMap = new Map();_x000D_
_x000D_
const keyString = 'a string',_x000D_
    keyObj = {},_x000D_
    keyFunc = function() {};_x000D_
_x000D_
// setting the values_x000D_
myMap.set(keyString, "value associated with 'a string'");_x000D_
myMap.set(keyObj, 'value associated with keyObj');_x000D_
myMap.set(keyFunc, 'value associated with keyFunc');_x000D_
_x000D_
console.log(myMap.size); // 3_x000D_
_x000D_
// getting the values_x000D_
console.log(myMap.get(keyString));    // "value associated with 'a string'"_x000D_
console.log(myMap.get(keyObj));       // "value associated with keyObj"_x000D_
console.log(myMap.get(keyFunc));      // "value associated with keyFunc"_x000D_
_x000D_
console.log(myMap.get('a string'));   // "value associated with 'a string'"_x000D_
                         // because keyString === 'a string'_x000D_
console.log(myMap.get({}));           // undefined, because keyObj !== {}_x000D_
console.log(myMap.get(function() {})) // undefined, because keyFunc !== function () {}

After trying a lot of things, I found working solutions that nuked the autofilled fields and replaced them with duplicated. Not to loose attached events, i came up with another (a bit lengthy) solution.

At each "input" event it swiftly attaches "change" events to all involved inputs. It tests if they have been autofilled. If yes, then dispatch a new text event that will trick the browser to think that the value has been changed by the user, thus allowing to remove the yellow background.

var initialFocusedElement = null
  , $inputs = $('input[type="text"]');

var removeAutofillStyle = function() {
  if($(this).is(':-webkit-autofill')) {
    var val = this.value;

    // Remove change event, we won't need it until next "input" event.
    $(this).off('change');

    // Dispatch a text event on the input field to trick the browser
    this.focus();
    event = document.createEvent('TextEvent');
    event.initTextEvent('textInput', true, true, window, '*');
    this.dispatchEvent(event);

    // Now the value has an asterisk appended, so restore it to the original
    this.value = val;

    // Always turn focus back to the element that received 
    // input that caused autofill
    initialFocusedElement.focus();
  }
};

var onChange = function() {
  // Testing if element has been autofilled doesn't 
  // work directly on change event.
  var self = this;
  setTimeout(function() {
    removeAutofillStyle.call(self);
  }, 1);
};

$inputs.on('input', function() {
  if(this === document.activeElement) {
    initialFocusedElement = this;

    // Autofilling will cause "change" event to be 
    // fired, so look for it
    $inputs.on('change', onChange);
  }
});

I think you can usually do what you need in a loop, which is much better than many onClick methods if it can be done.

Check out this answer for a demonstration of how to use a loop for a similar problem. How you construct your loop will depend on the needs of your onClick functions and how similar they are to one another. The end result is much less repetitive code that is easier to maintain.

Building on Brian's answer, the upload-pack path can be set permanently by running the following commands after cloning, which eliminates the need for --upload-pack on subsequent pull/fetch requests. Similarly, setting receive-pack eliminates the need for --receive-pack on push requests.

git config remote.origin.uploadpack /path/to/git-upload-pack
git config remote.origin.receivepack /path/to/git-receive-pack

These two commands are equivalent to adding the following lines to a repo's .git/config.

[remote "origin"]
    uploadpack = /path/to/git-upload-pack
    receivepack = /path/to/git-receive-pack

Frequent users of clone -u may be interested in the following aliases. myclone should be self-explanatory. myfetch/mypull/mypush can be used on repos whose config hasn't been modified as described above by replacing git push with git mypush, and so on.

[alias]
    myclone = clone --upload-pack /path/to/git-upload-pack
    myfetch = fetch --upload-pack /path/to/git-upload-pack
    mypull  = pull --upload-pack /path/to/git-upload-pack
    mypush  = push --receive-pack /path/to/git-receive-pack

Easiest way (which is surprisingly only mentioned in comments, hence why I am posting as an answer) is:

textview.setGravity(Gravity.CENTER)

From git stash --help

Recovering stashes that were cleared/dropped erroneously
   If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
   following incantation to get a list of stashes that are still in your repository, but not reachable any more:

       git fsck --unreachable |
       grep commit | cut -d\  -f3 |
       xargs git log --merges --no-walk --grep=WIP

This helped me better than the accepted answer with the same scenario.

campaign is a comprehensive solution for sending emails in Node, and it comes with a very simple API.

You instance it like this.

var client = require('campaign')({
  from: '[email protected]'
});

To send emails, you can use Mandrill, which is free and awesome. Just set your API key, like this:

process.env.MANDRILL_APIKEY = '<your api key>';

_{(if you want to send emails using another provider, check the docs)}

Then, when you want to send an email, you can do it like this:

client.sendString('<p>{{something}}</p>', {
  to: ['[email protected]', '[email protected]'],
  subject: 'Some Subject',
  preview': 'The first line',
  something: 'this is what replaces that thing in the template'
}, done);

The GitHub repo has pretty extensive documentation.

URLs are not resolved based on the file structure in the server side. URLs are resolved based on the real public web addresses of the resources in question. It's namely the webbrowser who has got to invoke them, not the webserver.

There are several ways to soften the pain:

JSF EL offers a shorthand to ${pageContext.request} in flavor of #{request}:

<li><a href="#{request.contextPath}/index.xhtml">Home</a></li>
<li><a href="#{request.contextPath}/about_us.xhtml">About us</a></li>

You can if necessary use <c:set> tag to make it yet shorter. Put it somewhere in the master template, it'll be available to all pages:

<c:set var="root" value="#{request.contextPath}/" />
...
<li><a href="#{root}index.xhtml">Home</a></li>
<li><a href="#{root}about_us.xhtml">About us</a></li>

JSF 2.x offers the <h:link> which can take a view ID relative to the context root in outcome and it will append the context path and FacesServlet mapping automatically:

<li><h:link value="Home" outcome="index" /></li>
<li><h:link value="About us" outcome="about_us" /></li>

HTML offers the <base> tag which makes all relative URLs in the document relative to this base. You could make use of it. Put it in the <h:head>.

<base href="#{request.requestURL.substring(0, request.requestURL.length() - request.requestURI.length())}#{request.contextPath}/" />
...
<li><a href="index.xhtml">Home</a></li>
<li><a href="about_us.xhtml">About us</a></li>

(note: this requires EL 2.2, otherwise you'd better use JSTL fn:substring(), see also this answer)

This should end up in the generated HTML something like as

<base href="http://example.com/webname/" />

Note that the <base> tag has a caveat: it makes all jump anchors in the page like <a href="#top"> relative to it as well! See also Is it recommended to use the <base> html tag? In JSF you could solve it like <a href="#{request.requestURI}#top">top</a> or <h:link value="top" fragment="top" />.

With Swift and KingFisher

   lazy var animatedPart: AnimatedImageView = {
        let img = AnimatedImageView()
        if let src = Bundle.main.url(forResource: "xx", withExtension: "gif"){
            img.kf.setImage(with: src)
        }
        return img
   }()

SQLiteDatabase sqldb = MyProvider.db;
String Query = "Select * from " + TABLE_NAME ;
Cursor cursor = sqldb.rawQuery(Query, null);
cursor.moveToLast(); //if you not place this cursor.getCount() always give same integer (1) or current position of cursor.

if(cursor.getCount()<=0){
    Log.v("tag","if 1 "+cursor.getCount());
    return false;
}
Log.v("tag","2 else  "+cursor.getCount());

return true;

if you not use cursor.moveToLast();

cursor.getCount() always give same integer (1) or current position of cursor.

Using regex:

var str   = "my car is red";
var stringArray = str.split(/(\s+)/);

console.log(stringArray); // ["my", " ", "car", " ", "is", " ", "red"] 

\s matches any character that is a whitespace, adding the plus makes it greedy, matching a group starting with characters and ending with whitespace, and the next group starts when there is a character after the whitespace etc.

This class does the trick. You can add new prefixes to the _prefixes static string array.

public static class StringExtensions
{
        public static string ToProperCase( this string original )
        {
            if( String.IsNullOrEmpty( original ) )
                return original;

            string result = _properNameRx.Replace( original.ToLower( CultureInfo.CurrentCulture ), HandleWord );
            return result;
        }

        public static string WordToProperCase( this string word )
        {
            if( String.IsNullOrEmpty( word ) )
                return word;

            if( word.Length > 1 )
                return Char.ToUpper( word[0], CultureInfo.CurrentCulture ) + word.Substring( 1 );

            return word.ToUpper( CultureInfo.CurrentCulture );
        }

        private static readonly Regex _properNameRx = new Regex( @"\b(\w+)\b" );
        private static readonly string[] _prefixes = {
                                                         "mc"
                                                     };

        private static string HandleWord( Match m )
        {
            string word = m.Groups[1].Value;

            foreach( string prefix in _prefixes )
            {
                if( word.StartsWith( prefix, StringComparison.CurrentCultureIgnoreCase ) )
                    return prefix.WordToProperCase() + word.Substring( prefix.Length ).WordToProperCase();
            }

            return word.WordToProperCase();
        }
}

An improved version of the PabloG code for Python 2/3:

    """
    u = urllib2.urlopen(url)

    scheme, netloc, path, query, fragment = urlparse.urlsplit(url)
    filename = os.path.basename(path)
    if not filename:
        filename = 'downloaded.file'
    if dest:
        filename = os.path.join(dest, filename)

    with open(filename, 'wb') as f:

You can use literals, it's more compact.

NSString* myString = [@(17) stringValue];

(Boxes as a NSNumber and uses its stringValue method)

Rename the module to something other than 'file'.

Then also be sure when you are calling the function that:

1)if you are importing the entire module, you reiterate the module name when calling it:

import module
module.function_name()

or

import pizza
pizza.pizza_function()

2)or if you are importing specific functions, functions with an alias, or all functions using *, you don't reiterate the module name:

from pizza import pizza_function
pizza_function()

or

from pizza import pizza_function as pf
pf()

or

from pizza import *
pizza_function()

I like

if ('string'[/^str/]) ...

You could use a std::stringstream. You can stream anything into it:

std::stringstream stream;
stream << 5.7;
stream << foo.bar;

std::string s = stream.str();

That should be a quite general approach. (Works only for C++, but you asked the question for this language too.)

You should create separate component, which will be listening to state changes and updating on every state change:

import store from '../reducers/store';

class Items extends Component {
  constructor(props) {
    super(props);

    this.state = {
      items: [],
    };

    store.subscribe(() => {
      // When state will be updated(in our case, when items will be fetched), 
      // we will update local component state and force component to rerender 
      // with new data.

      this.setState({
        items: store.getState().items;
      });
    });
  }

  render() {
    return (
      <div>
        {this.state.items.map((item) => <p> {item.title} </p> )}
      </div>
    );
  }
};

render(<Items />, document.getElementById('app'));

To install the plug-in, unzip the file into the Eclipse installation directory (or the plug-in directory depending on how the plug-in is packaged). The plug-in will not appear until you have restarted your workspace (Reboot Eclipse).

If you are trying to take a value from the same array and trying to update it, you can use the following code.

{  'condition': { 
                     'ts': [   '5a81625ba0ff65023c729022',
                               '5a8161ada0ff65023c728f51',
                               '5a815fb4a0ff65023c728dcd']}

If the collection is userData['condition']['ts'] and we need to

    for i,supplier in enumerate(userData['condition']['ts']): 
        supplier = ObjectId(supplier)
        userData['condition']['ts'][i] = supplier

The output will be

{'condition': {   'ts': [   ObjectId('5a81625ba0ff65023c729022'),
                            ObjectId('5a8161ada0ff65023c728f51'),
                            ObjectId('5a815fb4a0ff65023c728dcd')]}

Having the same exact issue with iOS 10.3 and Xcode 8.2.1. I'm not going to download the new Xcode beta just to fix this. Come on Apple!

To anyone reading this, you have to go to https://developer.apple.com/download/ and get the latest version, which might even be the beta, if the stable release doesn't work.

In the future, I would be aware if you update iOS on your devices you may break Xcode/iOS version so update wisely if you want to keep testing on it without jumping through hoops that Apple makes.

In the root folder where package.json is located, run npm outdated. You'll get outdated packages returned with some details. In those details, you'll see the current version number of the outdated package.

After then, open the package.json file and manually change the version number of the corresponding package.

Then delete the node_modules folder and run npm install. It should solve this issue.

Since this is the top Google answer for this, and it was way easier than I expected, here is the simple answer. Just subtract date1 from date2.

If this is your spreadsheet dates

     A            B
1 10/11/2017  12/1/2017

=(B1)-(A1)

results in 51, which is the number of days between a past date and a current date in Google spreadsheet

As long as it is a date format Google Sheets recognizes, you can directly subtract them and it will be correct.

To do it for a current date, just use the =TODAY() function.

=TODAY()-A1

While today works great, you can't use a date directly in the formula, you should referencing a cell that contains a date.

=(12/1/2017)-(10/1/2017) results in 0.0009915716411, not 61.

You just need to name the anonymous property the same on both sides

on new { t1.ProjectID, SecondProperty = true } equals 
   new { t2.ProjectID, SecondProperty = t2.Completed } into j1

Based on the comments of @svick, here is another implementation that might make more sense:

from t1 in Projects
from t2 in Tasks.Where(x => t1.ProjectID == x.ProjectID && x.Completed == true)
                .DefaultIfEmpty()
select new { t1.ProjectName, t2.TaskName }

I believe that there is some confusion here. The significant difference between cookie based authentication and what is now possible with HTML5 Web Storage is that browsers are built to send cookie data whenever they are requesting resources from the domain that set them. You can't prevent that without turning off cookies. Browsers do not send data from Web Storage unless code in the page sends it. And pages can only access data that they stored, not data stored by other pages.

So, a user worried about the way that their cookie data might be used by Google or Facebook might turn off cookies. But, they have less reason to turn off Web Storage (until the advertisers figure a way to use that as well).

So, that's the difference between cookie based and token based, the latter uses Web Storage.

If class has only one empty constructor (like Activity or Fragment etc, android classes):

Class<?> myClass = Class.forName("com.example.MyClass");    
Constructor<?> constructor = myClass.getConstructors()[0];

There's multiple ways of doing things in batch, so if escaping with a double percent %% isn't working for you, then you could try something like this:

set olddir=%CD%
cd /d "path of folder"
del "file name/ or *.txt etc..."
cd /d "%olddir%"

How this works:

set olddir=%CD% sets the variable "olddir" or any other variable name you like to the directory your batch file was launched from.

cd /d "path of folder" changes the current directory the batch will be looking at. keep the quotations and change path of folder to which ever path you aiming for.

del "file name/ or *.txt etc..." will delete the file in the current directory your batch is looking at, just don't add a directory path before the file name and just have the full file name or, to delete multiple files with the same extension with *.txt or whatever extension you need.

cd /d "%olddir%" takes the variable saved with your old path and goes back to the directory you started the batch with, its not important if you don't want the batch going back to its previous directory path, and like stated before the variable name can be changed to whatever you wish by changing the set olddir=%CD% line.

I solved the problem updating all packages from Android SDK Manager and also, I had to install Extras -> Android Support Repository.

Just trying to make it as easy as possible see code below:

- (void)viewDidLoad
{
   [self appWillEnterForeground]; //register For Application Will enterForeground
}


- (id)appWillEnterForeground{ //Application will enter foreground.

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(allFunctions)
                                                 name:UIApplicationWillEnterForegroundNotification
                                               object:nil];
    return self;
}


-(void) allFunctions{ //call any functions that need to be run when application will enter foreground 
    NSLog(@"calling all functions...application just came back from foreground");


}

One more method worth to mention here:

SQLCMD -S SEVERNAME -E -Q "SELECT COLUMN FROM TABLE" -s "," -o "c:\test.csv"

NOTE: I don't see any network admin let you run powershell scripts

    Gender :<br>
    <input type="radio" name="g" value="male"  <?php echo ($g=='Male')?'checked':'' ?>>male <br>
    <input type="radio" name="g" value="female"<?php echo ($g=='female')?'checked':'' ?>>female
            <?php echo $errors['g'];?>

Suppose a 9800GT GPU:

• it has 14 multiprocessors (SM)
• each SM has 8 thread-processors (AKA stream-processors, SP or cores)
• allows up to 512 threads per block
• warpsize is 32 (which means each of the 14x8=112 thread-processors can schedule up to 32 threads)

https://www.tutorialspoint.com/cuda/cuda_threads.htm

A block cannot have more active threads than 512 therefore __syncthreads can only synchronize limited number of threads. i.e. If you execute the following with 600 threads:

func1();
__syncthreads();
func2();
__syncthreads();

then the kernel must run twice and the order of execution will be:

1. func1 is executed for the first 512 threads
2. func2 is executed for the first 512 threads
3. func1 is executed for the remaining threads
4. func2 is executed for the remaining threads

Note:

The main point is __syncthreads is a block-wide operation and it does not synchronize all threads.

I'm not sure about the exact number of threads that __syncthreads can synchronize, since you can create a block with more than 512 threads and let the warp handle the scheduling. To my understanding it's more accurate to say: func1 is executed at least for the first 512 threads.

Before I edited this answer (back in 2010) I measured 14x8x32 threads were synchronized using __syncthreads.

I would greatly appreciate if someone test this again for a more accurate piece of information.

I recommend using this HttpURLConnectioninstead HttpGet. As HttpGet is already deprecated in Android API level 22.

HttpURLConnection httpcon;  
String url = null;
String data = null;
String result = null;
try {
  //Connect
  httpcon = (HttpURLConnection) ((new URL (url).openConnection()));
  httpcon.setDoOutput(true);
  httpcon.setRequestProperty("Content-Type", "application/json");
  httpcon.setRequestProperty("Accept", "application/json");
  httpcon.setRequestMethod("POST");
  httpcon.connect();

  //Write       
  OutputStream os = httpcon.getOutputStream();
  BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
  writer.write(data);
  writer.close();
  os.close();

  //Read        
  BufferedReader br = new BufferedReader(new InputStreamReader(httpcon.getInputStream(),"UTF-8"));

Do not use Class.newInstance(); see this thread: Why is Class.newInstance() evil?

Like other answers say, use Constructor.newInstance() instead.

You could try installing the 32 bit version of opencv

I had the same problem, I then realized that I was still running Network Conditioner on "Very Bad Network". Turning that off solved the issue.

Hope that helps someone.

The problem is, that openssl -verify does not do the job.

As Priyadi mentioned, openssl -verify stops at the first self signed certificate, hence you do not really verify the chain, as often the intermediate cert is self-signed.

I assume that you want to be 101% sure, that the certificate files are correct before you try to install them in the productive web service. This recipe here performs exactly this pre-flight-check.

Please note that the answer of Peter is correct, however the output of openssl -verify is no clue that everything really works afterwards. Yes, it might find some problems, but quite not all.

Here is a script which does the job to verify a certificate chain before you install it into Apache. Perhaps this can be enhanced with some of the more mystic OpenSSL magic, but I am no OpenSSL guru and following works:

Note that the output after EVERYTHING OK is the Apache setting, because people using NginX or haproxy usually can read and understand this perfectly, too ;)

There is a GitHub Gist of this which might have some updates

Prerequisites of this script:

• You have the trusted CA root data in /etc/ssl/certs as usual for example on Ubuntu
• Create a directory DIR where you store 3 files:
  • DIR/certificate.crt which contains the certificate
  • DIR/certificate.key which contains the secret key for your webservice (without passphrase)
  • DIR/certificate.bundle which contains the CA-Bundle. On how to prepare the bundle, see below.
• Now run the script: ./check DIR/certificate (this assumes that the script is named check in the current directory)
• There is a very unlikely case that the script outputs CA-Bundle is not needed. This means, that you (read: /etc/ssl/certs/) already trusts the signing certificate. But this is highly unlikely in the WWW.
• For this test port 4433 must be unused on your workstation. And better only run this in a secure environment, as it opens port 4433 shortly to the public, which might see foreign connects in a hostile environment.

How to create the certificate.bundle file?

In the WWW the trust chain usually looks like this:

• trusted certificate from /etc/ssl/certs
• unknown intermediate certificate(s), possibly cross signed by another CA
• your certificate (certificate.crt)

Now, the evaluation takes place from bottom to top, this means, first, your certificate is read, then the unknown intermediate certificate is needed, then perhaps the cross-signing-certificate and then /etc/ssl/certs is consulted to find the proper trusted certificate.

The ca-bundle must be made up in excactly the right processing order, this means, the first needed certificate (the intermediate certificate which signs your certificate) comes first in the bundle. Then the cross-signing-cert is needed.

Usually your CA (the authority who signed your certificate) will provide such a proper ca-bundle-file already. If not, you need to pick all the needed intermediate certificates and cat them together into a single file (on Unix). On Windows you can just open a text editor (like notepad.exe) and paste the certificates into the file, the first needed on top and following the others.

There is another thing. The files need to be in PEM format. Some CAs issue DER (a binary) format. PEM is easy to spot: It is ASCII readable. For mor on how to convert something into PEM, see How to convert .crt to .pem and follow the yellow brick road.

Example:

You have:

• intermediate2.crt the intermediate cert which signed your certificate.crt
• intermediate1.crt another intermediate cert, which singed intermediate2.crt
• crossigned.crt which is a cross signing certificate from another CA, which signed intermediate1.crt
• crossintermediate.crt which is another intermediate from the other CA which signed crossigned.crt (you probably will never ever see such a thing)

Then the proper cat would look like this:

cat intermediate2.crt intermediate1.crt crossigned.crt crossintermediate.crt > certificate.bundle

And how can you find out which files are needed or not and in which sequence?

Well, experiment, until the check tells you everything is OK. It is like a computer puzzle game to solve the riddle. Every. Single. Time. Even for pros. But you will get better each time you need to do this. So you are definitively not alone with all that pain. It's SSL, ya' know? SSL is probably one of the worst designs I ever saw in over 30 years of professional system administration. Ever wondered why crypto has not become mainstream in the last 30 years? That's why. 'nuff said.

This is the current, literally official way to set Chrome policies: https://support.google.com/chrome/a/answer/187202?hl=en

The Windows and Linux templates, as well as common policy documentation for all operating systems, can be found here: https://dl.google.com/dl/edgedl/chrome/policy/policy_templates.zip (Zip file of Google Chrome templates and documentation)

Instructions for Windows (with my additions):

Open the ADM or ADMX template you downloaded:

• Extract "chrome.adm" in the language of your choice from the "policy_templates.zip" downloaded earlier (e.g. "policy_templates.zip\windows\adm\en-US\chrome.adm").
• Navigate to Start > Run: gpedit.msc.
• Navigate to Local Computer Policy > Computer / User Configuration > Administrative Templates.
• Right-click Administrative Templates, and select Add/Remove Templates.
• Add the "chrome.adm" template via the dialog.
• Once complete, Classic Administrative Templates (ADM) / Google / Google Chrome folder will appear under Administrative Templates.
• No matter whether you add the template under Computer Configuration or User Configuration, the settings will appear in both places, so you can configure Chrome at a machine or a user level.

Once you're done with this, continue from step 5 of Antony Hatchkins' answer. After you have added the extension ID(s), you can check that the policy is working in Chrome by opening chrome://policy (search for ExtensionInstallWhitelist).

I just put this into a static class.

  const int WM_USER = 0x400;
  const int PBM_SETSTATE = WM_USER + 16;
  const int PBM_GETSTATE = WM_USER + 17;

  [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
  static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

  public enum ProgressBarStateEnum : int
  {
   Normal = 1,
   Error = 2,
   Paused = 3,
  }

  public static ProgressBarStateEnum GetState(this ProgressBar pBar)
  {
   return (ProgressBarStateEnum)(int)SendMessage(pBar.Handle, PBM_GETSTATE, IntPtr.Zero, IntPtr.Zero);
  }

  public static void SetState(this ProgressBar pBar, ProgressBarStateEnum state)
  {
   SendMessage(pBar.Handle, PBM_SETSTATE, (IntPtr)state, IntPtr.Zero);
  } 

Hope it helps,

I know it's an old thread, but I landed here several times via Google and think no given answer is really satisfying yet. Try using one of the following functions:

EDIT: As I'm getting some likes on this old thread, I wanna share an updated solution as well (basically putting my two previous functions together and automatically deciding whether it's a bar or hbar plot):

def label_bars(ax, bars, text_format, **kwargs):
    """
    Attaches a label on every bar of a regular or horizontal bar chart
    """
    ys = [bar.get_y() for bar in bars]
    y_is_constant = all(y == ys[0] for y in ys)  # -> regular bar chart, since all all bars start on the same y level (0)

    if y_is_constant:
        _label_bar(ax, bars, text_format, **kwargs)
    else:
        _label_barh(ax, bars, text_format, **kwargs)


def _label_bar(ax, bars, text_format, **kwargs):
    """
    Attach a text label to each bar displaying its y value
    """
    max_y_value = ax.get_ylim()[1]
    inside_distance = max_y_value * 0.05
    outside_distance = max_y_value * 0.01

    for bar in bars:
        text = text_format.format(bar.get_height())
        text_x = bar.get_x() + bar.get_width() / 2

        is_inside = bar.get_height() >= max_y_value * 0.15
        if is_inside:
            color = "white"
            text_y = bar.get_height() - inside_distance
        else:
            color = "black"
            text_y = bar.get_height() + outside_distance

        ax.text(text_x, text_y, text, ha='center', va='bottom', color=color, **kwargs)


def _label_barh(ax, bars, text_format, **kwargs):
    """
    Attach a text label to each bar displaying its y value
    Note: label always outside. otherwise it's too hard to control as numbers can be very long
    """
    max_x_value = ax.get_xlim()[1]
    distance = max_x_value * 0.0025

    for bar in bars:
        text = text_format.format(bar.get_width())

        text_x = bar.get_width() + distance
        text_y = bar.get_y() + bar.get_height() / 2

        ax.text(text_x, text_y, text, va='center', **kwargs)

Now you can use them for regular bar plots:

fig, ax = plt.subplots((5, 5))
bars = ax.bar(x_pos, values, width=0.5, align="center")
value_format = "{:.1%}"  # displaying values as percentage with one fractional digit
label_bars(ax, bars, value_format)

or for horizontal bar plots:

fig, ax = plt.subplots((5, 5))
horizontal_bars = ax.barh(y_pos, values, width=0.5, align="center")
value_format = "{:.1%}"  # displaying values as percentage with one fractional digit
label_bars(ax, horizontal_bars, value_format)

You need to set the logger level to the lowest you want to display. For example, if you want to display DEBUG messages, you need to set the logger level to DEBUG.

The Apache log4j manual has a section on Configuration.

i have this error using datatables.net

i fixed changing the default ajax Get to POST in te properties of the DataTable()

"ajax": {
        "url": "../ControllerName/MethodJson",
        "type": "POST"
    },

$(editFrame).contents().find("html").html();

I can't think of a reason to explicitly lose precision outside of display purposes. In that case, simply use string formatting.

double example = 12.34567;

Console.Out.WriteLine(example.ToString("#.000"));

I think the classic answer is to create a more decoupled application, which has no knowledge of which implementation will be used during runtime.

For example, we're a central payment provider, working with many payment providers around the world. However, when a request is made, I have no idea which payment processor I'm going to call. I could program one class with a ton of switch cases, such as:

class PaymentProcessor{

    private String type;

    public PaymentProcessor(String type){
        this.type = type;
    }

    public void authorize(){
        if (type.equals(Consts.PAYPAL)){
            // Do this;
        }
        else if(type.equals(Consts.OTHER_PROCESSOR)){
            // Do that;
        }
    }
}

Now imagine that now you'll need to maintain all this code in a single class because it's not decoupled properly, you can imagine that for every new processor you'll support, you'll need to create a new if // switch case for every method, this only gets more complicated, however, by using Dependency Injection (or Inversion of Control - as it's sometimes called, meaning that whoever controls the running of the program is known only at runtime, and not complication), you could achieve something very neat and maintainable.

class PaypalProcessor implements PaymentProcessor{

    public void authorize(){
        // Do PayPal authorization
    }
}

class OtherProcessor implements PaymentProcessor{

    public void authorize(){
        // Do other processor authorization
    }
}

class PaymentFactory{

    public static PaymentProcessor create(String type){

        switch(type){
            case Consts.PAYPAL;
                return new PaypalProcessor();

            case Consts.OTHER_PROCESSOR;
                return new OtherProcessor();
        }
    }
}

interface PaymentProcessor{
    void authorize();
}

** The code won't compile, I know :)

Since you want to append elements to existing list, you can use var List[Int] and then keep on adding elements to the same list. Note -> You have to make sure that you insert an element into existing list as follows:-

var l: List[int] = List() // creates an empty list

l = 3 :: l // adds 3 to the head of the list

l = 4 :: l // makes int 4 as the head of the list

// Now when you will print l, you will see two elements in the list ( 4, 3)

Are you looking for a pure bash solution? There are many approaches, but here's one.

for file in *_h.png ; do mv "$file" "${file%%_h.png}_half.png" ; done

This presumes that the only files in the current directory that end in _h.png are the ones you want to rename.

Much more specifically

for file in 0{5..6}_h.png ; do mv "$file" "${file/_h./_half.}" ; done

Presuming those two examples are your only. files.

For the general case, file renaming in has been covered before.

In my particular case, I had a similar error on a legacy website used in my organization. To solve the issue, I had to list the website a a "Trusted site".

To do so:

• Click the Tools button, and then Internet options.
• Go on the Security tab.
• Click on Trusted sites and then on the sites button.
• Enter the url of the website and click on Add.

I'm leaving this here in the remote case it will help someone.

I use Debian and I can simply type exec bash to achieve this. I can't say if it will work on all other distributions.

You can use .empty(), like this:

$("#foo").empty();

From the docs:

Remove all child nodes of the set of matched elements from the DOM.

There is a race condition in the accepted answer when 2 processes running under 2 different users trying to initialize the mutex at the same time. After the first process initializes the mutex, if the second process tries to initialize the mutex before the first process sets the access rule to everyone, an unauthorized exception will be thrown by the second process.

See below for corrected answer:

using System.Runtime.InteropServices;   //GuidAttribute
using System.Reflection;                //Assembly
using System.Threading;                 //Mutex
using System.Security.AccessControl;    //MutexAccessRule
using System.Security.Principal;        //SecurityIdentifier

static void Main(string[] args)
{
    // get application GUID as defined in AssemblyInfo.cs
    string appGuid = ((GuidAttribute)Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(GuidAttribute), false).GetValue(0)).Value.ToString();

    // unique id for global mutex - Global prefix means it is global to the machine
    string mutexId = string.Format( "Global\\{{{0}}}", appGuid );

    bool createdNew;
        // edited by Jeremy Wiebe to add example of setting up security for multi-user usage
        // edited by 'Marc' to work also on localized systems (don't use just "Everyone") 
        var allowEveryoneRule = new MutexAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), MutexRights.FullControl, AccessControlType.Allow);
        var securitySettings = new MutexSecurity();
        securitySettings.AddAccessRule(allowEveryoneRule);

        using (var mutex = new Mutex(false, mutexId, out createdNew, securitySettings))
        {

        // edited by acidzombie24
        var hasHandle = false;
        try
        {
            try
            {
                // note, you may want to time out here instead of waiting forever
                // edited by acidzombie24
                // mutex.WaitOne(Timeout.Infinite, false);
                hasHandle = mutex.WaitOne(5000, false);
                if (hasHandle == false)
                    throw new TimeoutException("Timeout waiting for exclusive access");
            }
            catch (AbandonedMutexException)
            {
                // Log the fact the mutex was abandoned in another process, it will still get aquired
                hasHandle = true;
            }

            // Perform your work here.
        }
        finally
        {
            // edited by acidzombie24, added if statemnet
            if(hasHandle)
                mutex.ReleaseMutex();
        }
    }
}

if use Inline CSS you use

<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>

Otherwise you can use class properties which related with a separate css file (styling your website) as like In CSS File

.imgSize {height:100px;width:100px;}

In HTML File

I always prefer to use tableView for inputTextField or scrollView. In combination with Notifications you can easily mange such behavior. (Note, if you use static cells in tableView such behaviour will manage automatically for you.)

// MARK: - Notifications
fileprivate func registerNotificaitions() {
    NotificationCenter.default.addObserver(self, selector: #selector(AddRemoteControlViewController.keyboardWillAppear(_:)),
                                           name: NSNotification.Name.UIKeyboardWillShow, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(AddRemoteControlViewController.keyboardWillDisappear),
                                           name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

fileprivate func unregisterNotifications() {
    NotificationCenter.default.removeObserver(self)
}

@objc fileprivate func keyboardWillAppear(_ notification: Notification) {
    if let keyboardHeight = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue.height {
        view.layoutIfNeeded()
        UIView.animate(withDuration: 0.3, animations: {
            let heightInset = keyboardHeight - self.addDeviceButton.frame.height
            self.tableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: heightInset, right: 0)
            self.view.layoutIfNeeded()
        }, completion: nil)
    }
}

@objc fileprivate func keyboardWillDisappear() {
    view.layoutIfNeeded()
    UIView.animate(withDuration: 0.3, animations: {
        self.tableView.contentInset = UIEdgeInsets.zero
        self.view.layoutIfNeeded()
    }, completion: nil)
}

You can always use normal functions:

function myPrivateFunction() {
  console.log("My property: " + this.prop);
}

class MyClass() {
  constructor() {
    this.prop = "myProp";
    myPrivateFunction.bind(this)();
  }
}

new MyClass(); // 'My property: myProp'

Had the same issue but mine was working for weeks before this. Realised I had changed my password on the server.

Remember to update your password if you've got the option selected 'Run whether user is logged on or not'

DECLARE @uuid VARCHAR(50)
SET @uuid = 'a89b1acd95016ae6b9c8aabb07da2010'

        SUBSTRING(@uuid, 1, 8) + '-' + SUBSTRING(@uuid, 9, 4) + '-' + SUBSTRING(@uuid, 13, 4) + '-' +
        SUBSTRING(@uuid, 17, 4) + '-' + SUBSTRING(@uuid, 21, 12)
        AS UNIQUEIDENTIFIER)

I was seeing this error unrelated to rails. It turned out my test was trying to use a port that was too high (greater than 65535).

This code will produce the error in question

require 'socket'
Socket.getaddrinfo("127.0.0.1", "65536")

In ES6, imports are live read-only views on exported-values. As a result, when you do import a from "somemodule";, you cannot assign to a no matter how you declare a in the module.

However, since imported variables are live views, they do change according to the "raw" exported variable in exports. Consider the following code (borrowed from the reference article below):

//------ lib.js ------
export let counter = 3;
export function incCounter() {
    counter++;
}

//------ main1.js ------
import { counter, incCounter } from './lib';

// The imported value `counter` is live
console.log(counter); // 3
incCounter();
console.log(counter); // 4

// The imported value can’t be changed
counter++; // TypeError

As you can see, the difference really lies in lib.js, not main1.js.

To summarize:

• You cannot assign to import-ed variables, no matter how you declare the corresponding variables in the module.
• The traditional let-vs-const semantics applies to the declared variable in the module.
  • If the variable is declared const, it cannot be reassigned or rebound in anywhere.
  • If the variable is declared let, it can only be reassigned in the module (but not the user). If it is changed, the import-ed variable changes accordingly.

public class PostFile {
    protected HttpPost httppost ;
    protected MultipartEntity mpEntity; 
    protected File filePath;

    public PostFile(final String fullUrl, final String filePath){
        this.httppost = new HttpPost(fullUrl);
        this.filePath = new File(filePath);        
        this.mpEntity = new MultipartEntity();
    }

    public void authenticate(String user, String password){
        String encoding = new String(Base64.encodeBase64((user+":"+password).getBytes()));
        httppost.setHeader("Authorization", "Basic " + encoding);
    }
    private void addParts() throws UnsupportedEncodingException{
        mpEntity.addPart("r", new StringBody("repository id"));
        mpEntity.addPart("g", new StringBody("group id"));
        mpEntity.addPart("a", new StringBody("artifact id"));
        mpEntity.addPart("v", new StringBody("version"));
        mpEntity.addPart("p", new StringBody("packaging"));
        mpEntity.addPart("e", new StringBody("extension"));

        mpEntity.addPart("file", new FileBody(this.filePath));

    }

    public String post() throws ClientProtocolException, IOException {
        HttpClient httpclient = new DefaultHttpClient();
        httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
        addParts();
        httppost.setEntity(mpEntity);
        HttpResponse response = httpclient.execute(httppost);

        System.out.println("executing request " + httppost.getRequestLine());
        System.out.println(httppost.getEntity().getContentLength());

        HttpEntity resEntity = response.getEntity();

        String statusLine = response.getStatusLine().toString();
        System.out.println(statusLine);
        if (resEntity != null) {
            System.out.println(EntityUtils.toString(resEntity));
        }
        if (resEntity != null) {
            resEntity.consumeContent();
        }
        return statusLine;
    }
}

There is also some more detail on the use of <mvc:annotation-driven /> in the Spring docs. In a nutshell, <mvc:annotation-driven /> gives you greater control over the inner workings of Spring MVC. You don't need to use it unless you need one or more of the features outlined in the aforementioned section of the docs.

Also, there are other "annotation-driven" tags available to provide additional functionality in other Spring modules. For example, <transaction:annotation-driven /> enables the use of the @Transaction annotation, <task:annotation-driven /> is required for @Scheduled et al...

Personally, I like this much better (which, granted, is just a different way of writing the currently selected "best answer"):

money = float(1234.5)
print('$' + format(money, ',.2f'))

Or, if you REALLY don't like "adding" multiple strings to combine them, you could do this instead:

money = float(1234.5)
print('${0}'.format(format(money, ',.2f')))

I just think both of these styles are a bit easier to read. :-)

(of course, you can still incorporate an If-Else to handle negative values as Eric suggests too)

I would like to present another answer to this as the currently accepted answer doesn't work for me (I use LibreOffice). This solution should work in Excel, LibreOffice and OpenOffice:

First, insert a new row at the beginning of the sheet. Within that row, define the names you need:

Then, in the menu bar, go to View -> Freeze Cells -> Freeze First Row. It'll look like this now:

Now whenever you scroll down in the document, the first row will be "pinned" to the top:

To acomplish the timezone change in Postgres 9.1 you must:

1.- Search in your "timezones" folder in /usr/share/postgresql/9.1/ for the appropiate file, in my case would be "America.txt", in it, search for the closest location to your zone and copy the first letters in the left column.

For example: if you are in "New York" or "Panama" it would be "EST":

#  - EST: Eastern Standard Time (Australia)
EST    -18000    # Eastern Standard Time (America)
                 #     (America/New_York)
                 #     (America/Panama)

2.- Uncomment the "timezone" line in your postgresql.conf file and put your timezone as shown:

#intervalstyle = 'postgres'
#timezone = '(defaults to server environment setting)'
timezone = 'EST'
#timezone_abbreviations = 'EST'     # Select the set of available time zone
                                        # abbreviations.  Currently, there are
                                        #   Default
                                        #   Australia

3.- Restart Postgres

If look into native Math object in JavaScript, you get the whole bunch of functions to work on numbers and values, etc...

Basically what you want to do is quite simple and native in JavaScript...

Imagine you have the number below:

const myValue = 56.4534931;

and now if you want to round it down to the nearest number, just simply do:

const rounded = Math.floor(myValue);

and you get:

56

If you want to round it up to the nearest number, just do:

const roundedUp = Math.ceil(myValue);

and you get:

57

Also Math.round just round it to higher or lower number depends on which one is closer to the flot number.

Also you can use of ~~ behind the float number, that will convert a float to a whole number.

You can use it like ~~myValue...

While I like the class decorator from Oz123, you could also do the following, which uses an explicit class wrapper and __new__ with a class Factory method returning the class within a closure:

class B(object):
    def __new__(cls, val):
        return cls.factory(val)

@classmethod
def factory(cls, val):
    private = {'var': 'test'}

    class InnerB(object):
        def __init__(self):
            self.variable = val
            pass

        @property
        def var(self):
            return private['var']

    return InnerB()

[Bb]in/

matches both upper and lower case

Set the owner of the directory to the user running apache. Often nobody on linux

chown nobody:nobody <dirname>

This way your folder will not be world writable, but still writable for apache :)

1. In Python an expression of X and Y returns Y, given that bool(X) == True or any of X or Y evaluate to False, e.g.:

   True and 20 
   >>> 20
   
   False and 20
   >>> False
   
   20 and []
   >>> []
   

2. Bitwise operator is simply not defined for lists. But it is defined for integers - operating over the binary representation of the numbers. Consider 16 (01000) and 31 (11111):

   16 & 31
   >>> 16
   

3. NumPy is not a psychic, it does not know, whether you mean that e.g. [False, False] should be equal to True in a logical expression. In this it overrides a standard Python behaviour, which is: "Any empty collection with len(collection) == 0 is False".

4. Probably an expected behaviour of NumPy's arrays's & operator.

Had a similar problem, but in Windows. I was trying to figure out how to open a large MySql sql file in Windows, and these are the steps I had to take:

• Go to the download website (http://dev.mysql.com/downloads/).
• Download the MySQL Community Server and install it (select the developer or full install, so it will install client and server tools).
• Open MySql Command Line Client from the Start menu.
• Enter your password used in install.

• In the prompt, mysql>, enter:

  CREATE DATABASE database_name;

  USE database_name;

  SOURCE myfile.sql

That should import your large file.

As all of these comments are true, you should note that as far as ICANN approved Arabic (Persian) and Chinese characters to be registered as Domain Name, all of the browser-making companies (Microsoft, Mozilla, Apple, etc.) have to support Unicode in URLs without any encoding, and those should be searchable by Google, etc.

So this issue will resolve ASAP.

In Python 3.8+ you can do

import hashlib

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    while chunk := f.read(8192):
        file_hash.update(chunk)

print(file_hash.digest())
print(file_hash.hexdigest())  # to get a printable str instead of bytes

On Python 3.7 and below:

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    chunk = f.read(8192)
    while chunk:
        file_hash.update(chunk)
        chunk = f.read(8192)

print(file_hash.hexdigest())

This reads the file 8192 (or 2¹³) bytes at a time instead of all at once with f.read() to use less memory.

Consider using hashlib.blake2b instead of md5 (just replace md5 with blake2b in the above snippets). It's cryptographically secure and faster than MD5.

def get_pair(line):
    key, sep, value = line.strip().partition(" ")
    return int(key), value

with open("file.txt") as fd:    
    d = dict(get_pair(line) for line in fd)

You can't. You need to create another php script to return the image data, e.g. getImage.php. Change catalog.php to:

<body>
<img src="getImage.php?id=1" width="175" height="200" />
</body>

Then getImage.php is

<?php

  $id = $_GET['id'];
  // do some validation here to ensure id is safe

  $link = mysql_connect("localhost", "root", "");
  mysql_select_db("dvddb");
  $sql = "SELECT dvdimage FROM dvd WHERE id=$id";
  $result = mysql_query("$sql");
  $row = mysql_fetch_assoc($result);
  mysql_close($link);

  header("Content-type: image/jpeg");
  echo $row['dvdimage'];
?>

This is what worked for me, even with major DOWN grade:

<Wix ...>
  <Product ...>
    <Property Id="REINSTALLMODE" Value="amus" />
    <MajorUpgrade AllowDowngrades="yes" />

A complete time-string contains:

• date
• time
• utcoffset [+HHMM or -HHMM]

For example:

1970-01-01 06:00:00 +0500 == 1970-01-01 01:00:00 +0000 == UNIX timestamp:3600

$ python3
>>> from datetime import datetime
>>> from calendar import timegm
>>> tm = '1970-01-01 06:00:00 +0500'
>>> fmt = '%Y-%m-%d %H:%M:%S %z'
>>> timegm(datetime.strptime(tm, fmt).utctimetuple())
3600

Note:

UNIX timestamp is a floating point number expressed in seconds since the epoch, in UTC.

Edit:

$ python3
>>> from datetime import datetime, timezone, timedelta
>>> from calendar import timegm
>>> dt = datetime(1970, 1, 1, 6, 0)
>>> tz = timezone(timedelta(hours=5))
>>> timegm(dt.replace(tzinfo=tz).utctimetuple())
3600

If the data set contains many rows it might be more efficient to join with a lookup table using data.table instead of nested ifelse().

Provided the lookup table below

lookup

     idnat     idbp   idnat2
1:  french mainland mainland
2:  french   colony overseas
3:  french overseas overseas
4: foreign  foreign  foreign

and a sample data set

library(data.table)
n_row <- 10L
set.seed(1L)
DT <- data.table(idnat = "french",
                 idbp = sample(c("mainland", "colony", "overseas", "foreign"), n_row, replace = TRUE))
DT[idbp == "foreign", idnat := "foreign"][]

      idnat     idbp
 1:  french   colony
 2:  french   colony
 3:  french overseas
 4: foreign  foreign
 5:  french mainland
 6: foreign  foreign
 7: foreign  foreign
 8:  french overseas
 9:  french overseas
10:  french mainland

then we can do an update while joining:

DT[lookup, on = .(idnat, idbp), idnat2 := i.idnat2][]

      idnat     idbp   idnat2
 1:  french   colony overseas
 2:  french   colony overseas
 3:  french overseas overseas
 4: foreign  foreign  foreign
 5:  french mainland mainland
 6: foreign  foreign  foreign
 7: foreign  foreign  foreign
 8:  french overseas overseas
 9:  french overseas overseas
10:  french mainland mainland

This issue occurs mostly when the maximum allowed concurrent connections to MySQL has exceeded. The max connections allowed is stored in the gloobal variable max_connections. You can check it by show global variables like max_connections; in MySQL

You can fix it by the following steps:

Step1:

Login to MySQL and run this command: SET GLOBAL max_connections = 100;

Now login to MySQL, the too many connection error fixed. This method does not require server restart.

Step2:

Using the above step1 you can resolve ths issue but max_connections will roll back to its default value when mysql is restarted.

In order to make the max_connection value permanent, update the my.cnf file.

Stop the MySQL server: Service mysql stop

Edit the configuration file my.cnf: vi /etc/mysql/my.cnf

Find the variable max_connections under mysqld section.

[mysql]

max_connections = 300

Set into higher value and save the file.

Start the server: Service mysql start

Note: Before increasing the max_connections variable value, make sure that, the server has adequate memory for new requests and connections.

MySQL pre-allocate memory for each connections and de-allocate only when the connection get closed. When new connections are querying, system should have enough resources such memory, network and computation power to satisfy the user requests.

Also, you should consider increasing the open tables limit in MySQL server to accommodate the additional request. And finally. it is very important to close the connections which are completed transaction on the server.

If using Android 2.2 and above (which is most devices now), the following code will get you what you want.

@Override
public void onBackPressed() {
    if (webView.canGoBack()) {
        webView.goBack();
    } else {
        super.onBackPressed();
    }
}

I know this is a little bit too late but it might just help someone.

In my case I already had a method to make the Object from a json Object and make json from the object. with this you can simply create a new instance of the object and use it to restore. For instance in a function parsing a final object

public void update(final Object object){ _x000D_
  final Object original = Object.makeFromJSON(object.toJSON()); _x000D_
  // the original is not affected by changes made to object _x000D_
}

The default behaviour of divs is to take the full width available in their parent container.
This is the same as if you'd give the inner divs a width of 100%.

By floating the divs, they ignore their default and size their width to fit the content. Everything behind it (in the HTML), is placed under the div (on the rendered page).
This is the reason that they align theirselves next to each other.

The float CSS property specifies that an element should be taken from the normal flow and placed along the left or right side of its container, where text and inline elements will wrap around it. A floating element is one where the computed value of float is not none.

Source: https://developer.mozilla.org/en-US/docs/Web/CSS/float

Get rid of the float, and the divs will be aligned under each other.
If this does not happen, you'll have some other css on divs or children of wrapper defining a floating behaviour or an inline display.

If you want to keep the float, for whatever reason, you can use clear on the 2nd div to reset the floating properties of elements before that element.
clear has 5 valid values: none | left | right | both | inherit. Clearing no floats (used to override inherited properties), left or right floats or both floats. Inherit means it'll inherit the behaviour of the parent element

Also, because of the default behaviour, you don't need to set the width and height on auto.
You only need this is you want to set a hardcoded height/width. E.g. 80% / 800px / 500em / ...

<div id="wrapper">
    <div id="inner1"></div>
    <div id="inner2"></div>
</div>

CSS is

#wrapper{
    margin-left:auto;
    margin-right:auto;
    height:auto; // this is not needed, as parent container, this div will size automaticly
    width:auto; // this is not needed, as parent container, this div will size automaticly
}

/*
You can get rid of the inner divs in the css, unless you want to style them.
If you want to style them identicly, you can use concatenation
*/
#inner1, #inner2 {
    border: 1px solid black;
}

I have combined all the above answers into a script that polls the counters and writes the measurements in the terminal:

$totalRam = (Get-CimInstance Win32_PhysicalMemory | Measure-Object -Property capacity -Sum).Sum
while($true) {
    $date = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
    $cpuTime = (Get-Counter '\Processor(_Total)\% Processor Time').CounterSamples.CookedValue
    $availMem = (Get-Counter '\Memory\Available MBytes').CounterSamples.CookedValue
    $date + ' > CPU: ' + $cpuTime.ToString("#,0.000") + '%, Avail. Mem.: ' + $availMem.ToString("N0") + 'MB (' + (104857600 * $availMem / $totalRam).ToString("#,0.0") + '%)'
    Start-Sleep -s 2
}

This produces the following output:

2020-02-01 10:56:55 > CPU: 0.797%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:56:59 > CPU: 0.447%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:57:03 > CPU: 0.089%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:57:07 > CPU: 0.000%, Avail. Mem.: 2,118MB (51.7%)

You can hit Ctrl+C to abort the loop.

So, you can connect to any Windows machine with this command:

Enter-PSSession -ComputerName MyServerName -Credential MyUserName

...paste it in, and run it, to get a "live" measurement. If connecting to the machine doesn't work directly, take a look here.

How about (works also for 0 and negatives):

int digits( int x ) { 
    return ( (bool) x * (int) log10( abs( x ) ) + 1 );
}

You can try like below with sqljdbc4-2.0.jar:

 public void getConnection() throws ClassNotFoundException, SQLException, IllegalAccessException, InstantiationException {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
        String url = "jdbc:sqlserver://<SERVER_IP>:<PORT_NO>;databaseName=" + DATABASE_NAME;
        Connection conn = DriverManager.getConnection(url, USERNAME, PASSWORD);
        System.out.println("DB Connection started");
        Statement sta = conn.createStatement();
        String Sql = "select * from TABLE_NAME";
        ResultSet rs = sta.executeQuery(Sql);
        while (rs.next()) {
            System.out.println(rs.getString("COLUMN_NAME"));
        }
    }

The answers above are good, but insufficient if you have more than 1 project (.csproj) in the same folder.

First, you easily add the "PackageReference" tag to the .csproj file (either manually, by using the nuget package manager or by using the dotnet add package command).

But then, you need to run the "restore" command manually so you can tell it which project you are trying to restore (if I just clicked the restore button that popped up, nothing happened). You can do that by running:

dotnet restore Project-File-Name.csproj

And that installs the package

Here is a solution using INDIRECT, which if you drag the formula, it will pick up different cells from the target sheet accordingly. It uses R1C1 notation and is not limited to working only on columns A-Z.

=INDIRECT("'"&$A$5&"'!R"&ROW()&"C"&COLUMN(),FALSE)

This version picks up the value from the target cell corresponding to the cell where the formula is placed. For example, if you place the formula in 'Summary'!B5 then it will pick up the value from 'SERVER-ONE'!B5, not 'SERVER-ONE'!G7 as specified in the original question. But you could easily add in offsets to the row and column to achieve the desired mapping in any case.

If you have a custom template and view you may exclude the field and use {{ modelform.instance.field }} to get the value.

also you may prefer to use in the view:

form.fields['field_name'].widget = forms.HiddenInput()

but I'm not sure it will protect save method on post.

Hope it helps.

You can use css like this:

overflow-y: scroll;
overflow-x: hidden;

regex: /^[a-zA-Z0-9_.]$/i

This works

For sorting an ArrayList you could use the following code snippet:

Collections.sort(studList, new Comparator<Student>(){
    public int compare(Student s1, Student s2) {
        return s1.getFirstName().compareToIgnoreCase(s2.getFirstName());
    }
});

In cordova 6.2.0, it has an easy way to create release build. refer to other steps here Steps 1, 2 and 4

cd cordova/ #change to root cordova folder
platforms/android/cordova/clean #clean if you want
cordova build android --release -- --keystore="/path/to/keystore" --storePassword=password --alias=alias_name #password will be prompted if you have any

Labels for break and continue were proposed in PEP 3136 back in 2007, but it was rejected. The Motivation section of the proposal illustrates several common (if inelegant) methods for imitating labeled break in Python.

It's not possible to achieve the required level of control over presentation in a regular textarea.

If you're OK with that, try CodeMirror or Ace or Monaco (used in MS VSCode).

From the duplicate thread - an obligatory wikipedia link: Comparison of JavaScript-based source code editors

This is usually what I use for counting the number of fields:

head -n 1 file.name | awk -F'|' '{print NF; exit}'

There's been a method for this for ages:

ruby -e 'puts Gem::Specification.all_names'

There is the .update() method :)

update([other]) Update the dictionary with the key/value pairs from other, overwriting existing keys. Return None.

update() accepts either another dictionary object or an iterable of key/value pairs (as tuples or other iterables of length two). If keyword arguments are specified, the dictionary is then updated with those key/value pairs: d.update(red=1, blue=2).

Changed in version 2.4: Allowed the argument to be an iterable of key/value pairs and allowed keyword arguments.

Addition to accepted answer -

If password not seen in logs, enable "org.springframework.boot.autoconfigure.security" logs.

If you fine-tune your logging configuration, ensure that the org.springframework.boot.autoconfigure.security category is set to log INFO messages, otherwise the default password will not be printed.

This is a peculiar question because it's not supposed to be a matter of choice.

When you launch the JVM, you specify a class to run, and it is the main() of this class where your program starts.

By init(), I assume you mean the JApplet method. When an applet is launched in the browser, the init() method of the specified applet is executed as the first order of business.

By run(), I assume you mean the method of Runnable. This is the method invoked when a new thread is started.

• main: program start
• init: applet start
• run: thread start

If Eclipse is running your run() method even though you have no main(), then it is doing something peculiar and non-standard, but not infeasible. Perhaps you should post a sample class that you've been running this way.

For us, the problem came down to same context settings in multiple configuration files. Check you've not duplicated the following in multiple config files.

<context:property-placeholder location="classpath*:/module.properties"/>
<context:component-scan base-package="...." />

You can even simply add the parameters to the end of the url:

$http.get('path/to/script.php?param=hello').success(function(data) {
    alert(data);
});

Paired with script.php:

<? var_dump($_GET); ?>

Resulting in the following javascript alert:

array(1) {  
    ["param"]=>  
    string(4) "hello"
}

Specify bash instead of sh when running the script. I personally noticed they are different under ubuntu 12.10:

bash script.sh arg0 ... argn

I recalled reading about this in the standard, so here goes:

See C11 standard which defines how the standard streams behave, as C++ programs interface the CRT, the C11 standard should govern the flushing policy here.

ISO/IEC 9899:201x

7.21.3 §7

At program startup, three text streams are predefined and need not be opened explicitly — standard input (for reading conventional input), standard output (for writing conventional output), and standard error (for writing diagnostic output). As initially opened, the standard error stream is not fully buffered; the standard input and standard output streams are fully buffered if and only if the stream can be determined not to refer to an interactive device.

7.21.3 §3

When a stream is unbuffered, characters are intended to appear from the source or at the destination as soon as possible. Otherwise characters may be accumulated and transmitted to or from the host environment as a block. When a stream is fully buffered, characters are intended to be transmitted to or from the host environment as a block when a buffer is filled. When a stream is line buffered, characters are intended to be transmitted to or from the host environment as a block when a new-line character is encountered. Furthermore, characters are intended to be transmitted as a block to the host environment when a buffer is filled, when input is requested on an unbuffered stream, or when input is requested on a line buffered stream that requires the transmission of characters from the host environment. Support for these characteristics is implementation-defined, and may be affected via the setbuf and setvbuf functions.

This means that std::cout and std::cin are fully buffered if and only if they are referring to a non-interactive device. In other words, if stdout is attached to a terminal then there is no difference in behavior.

However, if std::cout.sync_with_stdio(false) is called, then '\n' will not cause a flush even to interactive devices. Otherwise '\n' is equivalent to std::endl unless piping to files: c++ ref on std::endl.

You could do it like this:

 iterations = 10
 variables = 2

 output <- matrix(ncol=variables, nrow=iterations)

 for(i in 1:iterations){
  output[i,] <- runif(2)

 }

 output

and then turn it into a data.frame

 output <- data.frame(output)
 class(output)

what this does:

1. create a matrix with rows and columns according to the expected growth
2. insert 2 random numbers into the matrix
3. convert this into a dataframe after the loop has finished.

Have you tried overflow-y:auto ? It is not exactly what you want, as the scrollbar will appear only when needed.

 <td rowspan="2" style="text-align:left;vertical-align:top;padding:0">Save a lot</td>

That should do it.

Your logic condition is wrong. IIUC, what you want is:

import pyspark.sql.functions as f

df.filter((f.col('d')<5))\
    .filter(
        ((f.col('col1') != f.col('col3')) | 
         (f.col('col2') != f.col('col4')) & (f.col('col1') == f.col('col3')))
    )\
    .show()

I broke the filter() step into 2 calls for readability, but you could equivalently do it in one line.

Output:

+----+----+----+----+---+
|col1|col2|col3|col4|  d|
+----+----+----+----+---+
|   A|  xx|   D|  vv|  4|
|   A|   x|   A|  xx|  3|
|   E| xxx|   B|  vv|  3|
|   F|xxxx|   F| vvv|  4|
|   G| xxx|   G|  xx|  4|
+----+----+----+----+---+

You can always use command "mysqladmin shutdown"

something like....

SELECT f.*
      ,a1.city as from
      ,a2.city as to
FROM flights f
INNER JOIN airports a1
ON f.fairport = a1. code
INNER JOIN airports a2
ON f.tairport = a2. code

Bitstamp has live bitcoin data that are publicly available in JSON at this link. Do not try to access it more than 600 times in ten minutes or else they'll block your IP (plus, it's unnecessary anyway; read more here). The below is a C# approach to getting live data:

using (var WebClient = new System.Net.WebClient())
{
     var json = WebClient.DownloadString("https://www.bitstamp.net/api/ticker/");
     string value = Convert.ToString(json);
     // Parse/use from here
}

From here, you can parse the JSON and store it in a database (or with MongoDB insert it directly) and then access it.

For historic data (depending on the database - if that's how you approach it), do an insert from a flat file, which most databases allow you to use (for instance, with SQL Server you can do a BULK INSERT from a CSV file).

michal.kreuzman nice one I will have to say. It was useful.

However, the above works only for single digits: if you are going to use more than one digit, the structure is going to get misplaced since you are using spaces and not tabs.

As for my later codes I needed more digits than only 2, so I made a program myself.

It has some bugs now, again right now I am feeling lazy to correct them but it prints very beautifully and the nodes can take a larger number of digits.

The tree is not going to be as the question mentions but it is 270 degrees rotated :)

public static void printBinaryTree(TreeNode root, int level){
    if(root==null)
         return;
    printBinaryTree(root.right, level+1);
    if(level!=0){
        for(int i=0;i<level-1;i++)
            System.out.print("|\t");
        System.out.println("|-------"+root.val);
    }
    else
        System.out.println(root.val);
    printBinaryTree(root.left, level+1);
}    

Place this function with your own specified TreeNode and keep the level initially 0, and enjoy!

Here are some of the sample outputs:

|       |       |-------11
|       |-------10
|       |       |-------9
|-------8
|       |       |-------7
|       |-------6
|       |       |-------5
4
|       |-------3
|-------2
|       |-------1


|       |       |       |-------10
|       |       |-------9
|       |-------8
|       |       |-------7
|-------6
|       |-------5
4
|       |-------3
|-------2
|       |-------1

Only problem is with the extending branches; I will try to solve the problem as soon as possible but till then you can use it too.

#include<iostream>
#include<conio.h>
#include<stdlib.h>
using namespace std;
void displayBinary(int n)
{
       char bistr[1000];
       itoa(n,bistr,2);       //2 means binary u can convert n upto base 36
       printf("%s",bistr);

}

int main()
{
    int n;
    cin>>n;
    displayBinary(n);
    getch();
    return 0;
}

Have you tried the jtds driver for SQLServer?

Even easier

return new ArrayList<?>(getResultOfHibernateCallback(...))

SELECT * FROM user_cons_columns WHERE table_name = 'table_name';

I did the same thing that @Diode, the first answer, but i made the condition with a range of dates, i hope this example going to be useful for someone

e.g (the same code to example with array of dates)

var dateFrom = "02/06/2013";_x000D_
var dateTo = "02/09/2013";_x000D_
_x000D_
var d1 = dateFrom.split("/");_x000D_
var d2 = dateTo.split("/");_x000D_
_x000D_
var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]);  // -1 because months are from 0 to 11_x000D_
var to   = new Date(d2[2], parseInt(d2[1])-1, d2[0]); _x000D_
_x000D_
_x000D_
_x000D_
var dates= ["02/06/2013", "02/07/2013", "02/08/2013", "02/09/2013", "02/07/2013", "02/10/2013", "02/011/2013"];_x000D_
_x000D_
dates.forEach(element => {_x000D_
   let parts = element.split("/");_x000D_
   let date= new Date(parts[2], parseInt(parts[1]) - 1, parts[0]);_x000D_
        if (date >= from && date < to) {_x000D_
           console.log('dates in range', date);_x000D_
        }_x000D_
})

I run this command within a bash script, in particular to submit SGE jobs and batch process things:

/Path_to_matlab -nodisplay -nosplash -nodesktop < m_file.m

I was looking for a simple solution without having to install additional stuff and compatible with common hostings that allow SSH access.

I've ended up with this setup for my chat server:

-rwxr-xr-x  1 crazypoems psacln   309 ene 30 14:01 checkChatServerRunning.sh
-rw-r--r--  1 crazypoems psacln  3018 ene 30 13:12 class.chathandler.php
-rw-r--r--  1 crazypoems psacln    29 ene 30 14:05 cron.log
-rw-r--r--  1 crazypoems psacln  2560 ene 29 08:04 index.php
-rw-r--r--  1 crazypoems psacln  2672 ene 30 13:29 php-socket.php
-rwxr-xr-x  1 crazypoems psacln   310 ene 30 14:04 restartChatServer.sh
-rwxr-xr-x  1 crazypoems psacln   122 ene 30 13:28 startChatServer.sh
-rwxr-xr-x  1 crazypoems psacln   224 ene 30 13:56 stopChatServer.sh

And the scripts:

startChatServer.sh

#!/bin/bash
nohup /opt/plesk/php/5.6/bin/php -q /var/www/vhosts/crazypoems.org/httpdocs/chat/php-socket.php > /dev/null &

stopChatServer.sh

#!/bin/bash
PID=`ps -eaf | grep '/var/www/vhosts/crazypoems.org/httpdocs/chat/php-socket.php' | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
  echo "killing $PID"
  kill -9 $PID
else
  echo "not running"
fi

restartChatServer.sh

#!/bin/bash
PID=`ps -eaf | grep '/var/www/vhosts/crazypoems.org/httpdocs/chat/php-socket.php' | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
  echo "killing $PID"
  kill -9 $PID
else
  echo "not running"
fi
echo "Starting again"
/var/www/vhosts/crazypoems.org/httpdocs/chat/startChatServer.sh

And last but not least, I have put this last script on a cron job, to check if the "chat server is running", and if not, to start it:

Cron job every minute

-bash-4.1$ crontab -l
*       *       *       *       * /var/www/vhosts/crazypoems.org/httpdocs/chat/checkChatServerRunning.sh > /var/www/vhosts/crazypoems.org/httpdocs/chat/cron.log

checkChatServerRunning.sh

#!/bin/bash
PID=`ps -eaf | grep '/var/www/vhosts/crazypoems.org/httpdocs/chat/php-socket.php' | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
  echo "Chat server running on $PID"
else
  echo "Not running, going to start it"
  /var/www/vhosts/crazypoems.org/httpdocs/chat/startChatServer.sh
fi

So with this setup:

• I manually can control the service with the scripts when needed (eg: maintenance)
• The cron job will start the server on reboot, or on crash

I've used something like this before which addresses @scunliffes concern. It finds all instances of items with a class of (in this case .button), and assigns an ID and appends its index to the id name:

$(".button").attr('id', function (index) {_x000D_
 return "button-" + index;_x000D_
});

So let's say you have 3 items with the class name of .button on a page. The result would be adding a unique ID to all of them (in addition to their class of "button").

In this case, #button-0, #button-1, #button-2, respectively. This can come in very handy. Simply replace ".button" in the first line with whatever class you want to target, and replace "button" in the return statement with whatever you'd like your unique ID to be. Hope this helps!

Just had the same error in my project, but different reason. In my case I had an IBOutlet setup with the name "View" in my custom UITableViewController class. I knew "view" was special because that is a member of the base class, but I didn't think View (different case) would also be a problem. I guess some areas of Cocoa are not case-sensitive, and probably loading a xib is one of those areas. So I just renamed it to DefaultView and all is good now.

Use tf.train.Saver to save a model, remerber, you need to specify the var_list, if you want to reduce the model size. The val_list can be tf.trainable_variables or tf.global_variables.

function findIndicesOf(haystack, needle)
{
    var indices = [];

    var j = 0;
    for (var i = 0; i < haystack.length; ++i) {
        if (haystack[i] == needle)
            indices[j++] = i;
    }
    return indices;
}

pass array to haystack and Math.max(...array) to needle. This will give all max elements of the array, and it is more extensible (for example, you also need to find min values)

If you need to install an older version (for example 0.25):

pod _0.25.0_ install

I'd create a cte and do an inner join. It's not efficient but it's convenient

with table as (
SELECT DATE, STATUS, TITLE, ROW_NUMBER() 
OVER (PARTITION BY DATE, STATUS,  TITLE ORDER BY QUANTITY ASC) AS Row_Num
 FROM TABLE)

select *

from table t
join select(
max(Row_Num) as Row_Num
,DATE
,STATUS
,TITLE
from table 
group by date, status, title) t2  
on t2.Row_Num = t.Row_Num and t2
and t2.date = t.date
and t2.title = t.title

Here's a list of the registered URI schemes. Each one has an RFC - a document defining it, which is almost a standard. The RFC tells the developers of new applications (such as browsers, ftp clients, etc.) what they need to support. If you need a new base-level protocol, you can use an unregistered one. The other answers tell you how. Please keep in mind you can do lots of things with the existing protocols, thus gaining their existing implementations.
