Different hosting providers have different procedures for doing this, so I would ask on their forums or file a support request.

If you can't turn them off, you could always using something like this which will escape input regardless of whether magic quotes are on or off:

//using mysqli

public function escapeString($stringToBeEscaped) {

    return $this->getConnection()->real_escape_string(stripslashes($stringToBeEscaped));
}

Do a row div.

A callback is a self-addressed stamped envelope. When you call a function, that is like sending a letter. If you want that function to call another function you provide that information in the form of a reference or address.

LARAVEL 5.5 AND UP

The @php blade directive no longer accepts inline tags. Instead, use the full form of the directive:

@php
$i = 1
@endphp

LARAVEL 5.2 AND UP

You can just use:

@php ($i = 1)

Or you can use it in a block statement:

@php
$i = 1
@endphp

LARAVEL 5

Extend Blade like this:

/*
|--------------------------------------------------------------------------
| Extend blade so we can define a variable
| <code>
| @define $variable = "whatever"
| </code>
|--------------------------------------------------------------------------
*/

\Blade::extend(function($value) {
    return preg_replace('/\@define(.+)/', '<?php ${1}; ?>', $value);
});

Then do one of the following:

Quick solution: If you are lazy, just put the code in the boot() function of the AppServiceProvider.php.

Nicer solution: Create an own service provider. See https://stackoverflow.com/a/28641054/2169147 on how to extend blade in Laravel 5. It's a bit more work this way, but a good exercise on how to use Providers :)

LARAVEL 4

You can just put the above code on the bottom of app/start/global.php (or any other place if you feel that is better).

After the above changes, you can use:

@define $i = 1

to define a variable.

Empty dictionaries evaluate to False in Python:

>>> dct = {}
>>> bool(dct)
False
>>> not dct
True
>>>

Thus, your isEmpty function is unnecessary. All you need to do is:

def onMessage(self, socket, message):
    if not self.users:
        socket.send("Nobody is online, please use REGISTER command" \
                    " in order to register into the server")
    else:
        socket.send("ONLINE " + ' ' .join(self.users.keys()))

There is one example where in actually kills your performance.

If you use in on a O(1) container that only implements __getitem__ and has_key() but not __contains__ you will turn an O(1) search into an O(N) search (as in falls back to a linear search via __getitem__).

Fix is obviously trivial:

def __contains__(self, x):
    return self.has_key(x)

Imagine a counter with an initial value of 0.

For every loop, increment the counter value by 1 using $counter = 0;

The final counter value returned by the loop will be the number of iterations of your for loop. Find the code below:

$counter = 0;
foreach ($Contents as $item) {
    $counter++;
    $item[number];// if there are 15 $item[number] in this foreach, I want get the value `: 15`
}

Try that.

Error Message: Gradle sync failed: Minimum supported Gradle version is 4.9. Current version is 4.1-milestone-1. If using the gradle wrapper, try editing the distributionUrl in SampleProj/app/gradle/wrapper/gradle-wrapper.properties to gradle-4.9-all.zip

I am using Android studio IDE version 3.2 beta 2.

Solution: When we open gradle-wrapper.properties file in IDE it shows correct distributionUrl. but originally it has not been updated. So change the distributionUrl property manually.

Example : open a gradle-wrapper.properties file in notepad or any other editor. /Project/app/gradle/wrapper/gradle-wrapper.properties and change distributionUrl property to like this

distributionUrl=https\://services.gradle.org/distributions/gradle-4.9-all.zip

In some previous backups, your bad objects may have been packed in different files or may be loose objects yet. So your objects may be recovered.

It seems there are a few bad objects in your database. So you could do it the manual way.

Because of git hash-object, git mktree and git commit-tree do not write the objects because they are found in the pack, then start doing this:

mv .git/objects/pack/* <somewhere>
for i in <somewhere>/*.pack; do
  git unpack-objects -r < $i
done
rm <somewhere>/*

(Your packs are moved out from the repository, and unpacked again in it; only the good objects are now in the database)

You can do:

git cat-file -t 6c8cae4994b5ec7891ccb1527d30634997a978ee

and check the type of the object.

If the type is blob: retrieve the contents of the file from previous backups (with git show or git cat-file or git unpack-file; then you may git hash-object -w to rewrite the object in your current repository.

If the type is tree: you could use git ls-tree to recover the tree from previous backups; then git mktree to write it again in your current repository.

If the type is commit: the same with git show, git cat-file and git commit-tree.

Of course, I would backup your original working copy before starting this process.

Also, take a look at How to Recover Corrupted Blob Object.

Your problem is that despite the Expires: header, your browser is re-using its in-memory copy of the image from before it was updated, rather than even checking its cache.

I had a very similar situation uploading product images in the admin backend for a store-like site, and in my case I decided the best option was to use javascript to force an image refresh, without using any of the URL-modifying techniques other people have already mentioned here. Instead, I put the image URL into a hidden IFRAME, called location.reload(true) on the IFRAME's window, and then replaced my image on the page. This forces a refresh of the image, not just on the page I'm on, but also on any later pages I visit - without either client or server having to remember any URL querystring or fragment identifier parameters.

I posted some code to do this in my answer here.

This should work for you.

In .html:

<div class="my_class" (click)="clickEvent()"  
    [ngClass]="status ? 'success' : 'danger'">                
     Some content
</div>

In .ts:

status: boolean = false;
clickEvent(){
    this.status = !this.status;       
}

Add an entry in /etc/profile that executes the script. This will be run during every log-on. If you are only doing this for your own account, use one of your login scripts (e.g. .bash_profile) to run it.

Come 2021 and Spring Boot 2.4 the solution I have found is to have 3 properties files

• src/main/resources/application.yml - contains the application's default props
• src/test/resources/application.yml - sets the profile to 'test', and imports properties from 'main'
• src/test/resources/application-test.yml - contains test-specific profiles, which will override 'main'

Here is the content of src/test/resources/application.yml:

# for testing, set default profile to 'test'
spring.profiles.active: "test"
# and import the 'main' properties
spring.config.import: file:src/main/resources/application.yml

For example, if src/main/resources/application.yml has the content

ip-address: "10.7.0.1"
username: admin

and src/test/resources/application-test.yml has

ip-address: "999.999.999.999"
run-integration-test: true

Then (assuming there are no other profiles)...

when running tests,

profiles=test
--
ip-address=999.999.999.999
username=admin
run-integration-test=true

and when running the application normally

profiles=none
--
ip-address=10.7.0.1
username=admin
run-integration-test <undefined>

TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm service.

The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.

To restart the service:

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart        # typical
/etc/init.d/php5-fpm restart       # debian-style
/etc/init.d/php7.0-fpm restart     # debian-style PHP 7

Using service wrapper script

service php-fpm restart        # typical
service php5-fpm restart       # debian-style
service php7.0-fpm restart.    # debian-style PHP 7

Using Upstart (e.g. ubuntu):

restart php7.0-fpm         # typical (ubuntu is debian-based) PHP 7
restart php5-fpm           # typical (ubuntu is debian-based)
restart php-fpm            # uncommon

Using systemd (newer servers):

systemctl restart php-fpm.service        # typical
systemctl restart php5-fpm.service       # uncommon
systemctl restart php7.0-fpm.service     # uncommon PHP 7

Or whatever the equivalent is on your system.

The above commands taken directly from this server fault answer

As stated before, don't use syscall. You can use standard C library calls though, but be aware that the stack MUST be 16 byte aligned per Apple's IA32 function call ABI.

If you don't align the stack, your program will crash in __dyld_misaligned_stack_error when you make a call into any of the libraries or frameworks.

The following snippet assembles and runs on my system:

; File: hello.asm
; Build: nasm -f macho hello.asm && gcc -o hello hello.o

SECTION .rodata
hello.msg db 'Hello, World!',0x0a,0x00

SECTION .text

extern _printf ; could also use _puts...
GLOBAL _main

; aligns esp to 16 bytes in preparation for calling a C library function
; arg is number of bytes to pad for function arguments, this should be a multiple of 16
; unless you are using push/pop to load args
%macro clib_prolog 1
    mov ebx, esp        ; remember current esp
    and esp, 0xFFFFFFF0 ; align to next 16 byte boundary (could be zero offset!)
    sub esp, 12         ; skip ahead 12 so we can store original esp
    push ebx            ; store esp (16 bytes aligned again)
    sub esp, %1         ; pad for arguments (make conditional?)
%endmacro

; arg must match most recent call to clib_prolog
%macro clib_epilog 1
    add esp, %1         ; remove arg padding
    pop ebx             ; get original esp
    mov esp, ebx        ; restore
%endmacro

_main:
    ; set up stack frame
    push ebp
    mov ebp, esp
    push ebx

    clib_prolog 16
    mov dword [esp], hello.msg
    call _printf
    ; can make more clib calls here...
    clib_epilog 16

    ; tear down stack frame
    pop ebx
    mov esp, ebp
    pop ebp
    mov eax, 0          ; set return code
    ret

As with many questions lately, Java 8 to the rescue:

Java 8 added a new static method to java.lang.String which does exactly what you want:

public static String join(CharSequence delimeter, CharSequence... elements);

Using it:

String s = String.join(", ", new String[] {"Hello", "World", "!"});

Results in:

"Hello, World, !"

Starting with MySQL 8, you can finally use window functions also in MySQL: https://dev.mysql.com/doc/refman/8.0/en/window-functions.html

Your query can be written exactly the same way:

SELECT RANK() OVER (PARTITION BY Gender ORDER BY Age) AS `Partition by Gender`, 
  FirstName, 
  Age,
  Gender 
FROM Person

You could theoretically do the entire thing as simply:

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

namespace consoleHelloWorld {
class Program {
    static void Main(string[] args) {
       Console.WriteLine(DateTime.Now.ToString("MM.dd.yyyy"));
    }
  }
}

Use the numpy.corrcoef function instead of numpy.correlate to calculate the statistical correlation for a lag of t:

def autocorr(x, t=1):
    return numpy.corrcoef(numpy.array([x[:-t], x[t:]]))

If you are talking about Python's actual array (available through import array from array), then the principle of least astonishment applies and you can check whether it is empty the same way you'd check if a list is empty.

from array import array
an_array = array('i') # an array of ints

if an_array:
    print("this won't be printed")

an_array.append(3)

if an_array:
    print("this will be printed")

One of the way to browse your database is to use questoid sqlite manager.

# 1. Download questoid manager from this link .

# 2. Drop this file into your eclipse --> dropins.

# 3. Restart your eclipse.

# 4. Now go to your file explorer and click your database. you can find a blue database icon enabled in the top right corner.

# 5. Double click the icon and you can see ur inserted fields/tables/ in the database

All static member and function should be inside companion block

  companion object {
    @JvmStatic
    fun main(args: Array<String>) {
    }

    fun staticMethod() {
    }
  }

user2532030's answer is the correct and most simple answer.

I just want to add, that in the case, where the value of the determining cell is not suitable for a RegEx-match, I found the following syntax to work the same, only with numerical values, relations et.c.:

[Custom formula is]
=$B$2:$B = "Complete"
Range: A2:Z1000

If column 2 of any row (row 2 in script, but the leading $ means, this could be any row) textually equals "Complete", do X for the Range of the entire sheet (excluding header row (i.e. starting from A2 instead of A1)).

But obviously, this method allows also for numerical operations (even though this does not apply for op's question), like:

=$B$2:$B > $C$2:$C

So, do stuff, if the value of col B in any row is higher than col C value.

One last thing: Most likely, this applies only to me, but I was stupid enough to repeatedly forget to choose Custom formula is in the drop-down, leaving it at Text contains. Obviously, this won't float...

You need to use ?param instead of @param when performing queries to MySQL

 str_carSql = "insert into members_car (car_id, member_id, model, color, chassis_id, plate_number, code) values (?id,?m_id,?model,?color,?ch_id,?pt_num,?code)"
        sqlCommand.Connection = SQLConnection
        sqlCommand.CommandText = str_carSql
        sqlCommand.Parameters.AddWithValue("?id", TextBox20.Text)
        sqlCommand.Parameters.AddWithValue("?m_id", TextBox20.Text)
        sqlCommand.Parameters.AddWithValue("?model", TextBox23.Text)
        sqlCommand.Parameters.AddWithValue("?color", TextBox24.Text)
        sqlCommand.Parameters.AddWithValue("?ch_id", TextBox22.Text)
        sqlCommand.Parameters.AddWithValue("?pt_num", TextBox21.Text)
        sqlCommand.Parameters.AddWithValue("?code", ComboBox1.SelectedItem)
        sqlCommand.ExecuteNonQuery()

Change the catch block to see the actual exception:

  Catch ex As Exception
         MsgBox(ex.Message)   
          Return False

    End Try

Right click on the folder which is under SVN control, go to TortoiseSVN ? Show log. Write down the revision you want to revert to and then go to TortoiseSVN ? Update to revision....

You could use replicate or sapply:

R> colMeans(replicate(10000, sample(100, size=815, replace=TRUE, prob=NULL))) R> sapply(seq_len(10000), function(...) mean(sample(100, size=815, replace=TRUE, prob=NULL))) 

replicate is a wrapper for the common use of sapply for repeated evaluation of an expression (which will usually involve random number generation).

Conventional wisdom suggests that index choice should be based on cardinality. They'll say,

For a low cardinality column like GENDER, use bitmap. For a high cardinality like LAST_NAME, use b-tree.

This is not the case with Oracle, where index choice should instead be based on the type of application (OLTP vs. OLAP). DML on tables with bitmap indexes can cause serious lock contention. On the other hand, the Oracle CBO can easily combine multiple bitmap indexes together, and bitmap indexes can be used to search for nulls. As a general rule:

For an OLTP system with frequent DML and routine queries, use btree. For an OLAP system with infrequent DML and adhoc queries, use bitmap.

I'm not sure if this applies to other databases, comments are welcome. The following articles discuss the subject further:

• Bitmap Index vs. B-tree Index: Which and When?
• Understanding Bitmap Indexes

There are commercial products such as ionCube (which I use), source guardian, and Zen Guard.

There are also postings on the net which claim they can reverse engineer the encoded programs. How reliable they are is questionable, since I have never used them.

Note that most of these solutions require an encoder to be installed on their servers. So you may want to make sure your client is comfortable with that.

Thanks for this - I was having a similar issue, as I'm trying to programatically relate objects will hierarchical class names, even though those names might not necessarily be known to my script.

In my script, I want an <a> tag to turn help text on/off by giving the <a> tag [some_class] plus the class of toggle, and then giving it's help text the class of [some_class]_toggle. This code is successfully finding the related elements using jQuery:

$("a.toggle").toggle(function(){toggleHelp($(this), false);}, function(){toggleHelp($(this), true);});

function toggleHelp(obj, mode){
    var classList = obj.attr('class').split(/\s+/);
    $.each( classList, function(index, item){
    if (item.indexOf("_toggle") > 0) {
       var targetClass = "." + item.replace("_toggle", "");
       if(mode===false){$(targetClass).removeClass("off");}
       else{$(targetClass).addClass("off");}
    }
    });
} 

Assuming the program is run in the usual way (./a.out) so that it has one argument, and ignoring the compiler type warnings then:

#include <stdio.h>
#include <stdlib.h>

void main(int i) {
    static void (*cont[2])(int) = { main, exit };
    printf("%d\n", i);
    cont[i/1000](i+1);
}

How about just mapping ....

Array(n).map((value, index) ....) is 80% of the way there. But for some odd reason it does not work. But there is a workaround.

Array(n).map((v,i) => i) // does not work
Array(n).fill().map((v,i) => i) // does dork

For a range

Array(end-start+1).fill().map((v,i) => i + start) // gives you a range

Odd, these two iterators return the same result: Array(end-start+1).entries() and Array(end-start+1).fill().entries()

Comparison sorts (i.e. ones based on comparing elements) cannot possibly be faster than n log n. It doesn't matter what the underlying data structure is. See Wikipedia.

Other kinds of sort that take advantage of there being lots of identical elements in the list (such as the counting sort), or some expected distribution of elements in the list, are faster, though I can't think of any that work particularly well on a linked list.

For a JQM+PhoneGap app the following worked for me.

The following was the minimum I had to go to get this to work. I was actually experiencing a stall due to the buffering while spawning ajax requests when the user pressed the back button. Pausing the video in Chrome and the Android browser kept it buffering. The non-async ajax request would get stuck waiting for the buffering to finish, which it never would.

Binding this to the beforepagehide event fixed it.

 $("#SOME_JQM_PAGE").live("pagebeforehide", function(event)
 {
           $("video").each(function () 
           { 
               logger.debug("PAUSE VIDEO");
               this.pause();
               this.src = "";
           });
 });

This will clear every video tag on the page.

The important part is this.src = "";

I couldn't find mysql socket at all so reinstalled mysql server(all tables and phpmyadmin settings were preserved). Here are the commands:

1) Install

sudo apt-get install mysql-server

2) Follow terminal configuration steps

sudo mysql_secure_installation

3) Check status: (Should return "Active: active (running)")

systemctl status mysql.service

printf("price: %d, %f",temp,ftemp); 
              ^^^

This is your problem. Since the arguments are type double and float, you should be using %f for both (since printf is a variadic function, ftemp will be promoted to double).

%d expects the corresponding argument to be type int, not double.

Variadic functions like printf don't really know the types of the arguments in the variable argument list; you have to tell it with the conversion specifier. Since you told printf that the first argument is supposed to be an int, printf will take the next sizeof (int) bytes from the argument list and interpret it as an integer value; hence the first garbage number.

Now, it's almost guaranteed that sizeof (int) < sizeof (double), so when printf takes the next sizeof (double) bytes from the argument list, it's probably starting with the middle byte of temp, rather than the first byte of ftemp; hence the second garbage number.

Use %f for both.

I'm still kind of learning Javascript but I came up with this function in C awhile ago, which uses math and a while loop rather than a string so I re-wrote it for Javascript. Maybe this could be done recursively somehow but I still haven't really grasped the concept :( This is the best I could come up with. I'm not sure how large of numbers it works with, it worked when I put in a hundred digits.

function count_digits(n) {
    numDigits = 0;
    integers = Math.abs(n);

    while (integers > 0) {
        integers = (integers - integers % 10) / 10;
        numDigits++;
    }
    return numDigits;
}

edit: only works with integer values

Regarding this link you can make the first solution provided by krzyk permanent by executing:

echo 'export HISTTIMEFORMAT="%d/%m/%y %T "' >> ~/.bash_profile
source ~/.bash_profile

There's now a doesObjectExist method in the official Java API.

Enjoy!

The way I could mitigate the JSON Array to collection of LinkedHashMap objects problem was by using CollectionType rather than a TypeReference . This is what I did and worked:

public <T> List<T> jsonArrayToObjectList(String json, Class<T> tClass) throws IOException {
    ObjectMapper mapper = new ObjectMapper();
    CollectionType listType = mapper.getTypeFactory().constructCollectionType(ArrayList.class, tClass);
    List<T> ts = mapper.readValue(json, listType);
    LOGGER.debug("class name: {}", ts.get(0).getClass().getName());
    return ts;
}

Using the TypeReference, I was still getting an ArrayList of LinkedHashMaps, i.e. does not work:

public <T> List<T> jsonArrayToObjectList(String json, Class<T> tClass) throws IOException {
    ObjectMapper mapper = new ObjectMapper();
    List<T> ts = mapper.readValue(json, new TypeReference<List<T>>(){});
    LOGGER.debug("class name: {}", ts.get(0).getClass().getName());
    return ts;
}

First check the $_GET['s'] is set or not. Change your conditions like this

<?php
if (isset($_GET['s']) && $_GET['s'] == 'jwshxnsyllabus')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml',         '../bibliographies/jwshxnbibliography_')\">";
elseif (isset($_GET['s']) && $_GET['s'] == 'aquinas')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">"; 
elseif (isset($_GET['s']) && $_GET['s'] == 'POP2')
echo "<body onload=\"loadSyllabi('POP2')\">";
elseif (isset($_GET['s']) && $_GET['s'] == null)
echo "<body>"
?>

And also handle properly your ifelse conditions

Using brew

First install brew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

And then install wget with brew:

brew install wget

Using MacPorts

First, download and run MacPorts installer (.pkg)

And then install wget:

sudo port install wget

The shortest way is indeed just

String fileContents = new File('/path/to/file').text

but in this case you have no control on how the bytes in the file are interpreted as characters. AFAIK groovy tries to guess the encoding here by looking at the file content.

If you want a specific character encoding you can specify a charset name with

String fileContents = new File('/path/to/file').getText('UTF-8')

See API docs on File.getText(String) for further reference.

You can use %in%

  data[data$Code %in% selected,]
  Code Value
1    A     1
2    B     2
7    A     3
8    A     4

Find the process id of your webapp/java process from top. Use jmap heap to get the heap allocation. I tested this on AWS-Ec2 for elastic beanstalk

As other noted you have several options. If you want only mathematical functions. You can import only Darwin.

import Darwin

If you want mathematical functions and other standard classes and functions. You can import Foundation.

import Foundation

If you want everything and also classes for user interface, it depends if your playground is for OS X or iOS.

For OS X, you need import Cocoa.

import Cocoa

For iOS, you need import UIKit.

import UIKit

You can easily discover your playground platform by opening File Inspector (??1).

Just wrap another div around it, which has the border and the padding you want.

If you are using the Gradle Wrapper (the recommended option in Android Studio), you enable stacktrace by running gradlew compileDebug --stacktrace from the command line in the root folder of your project (where the gradlew file is).

If you are not using the gradle wrapper, you use gradle compileDebug --stacktrace instead (presumably).

You don't really need to run with --stacktrace though, running gradlew compileDebug by itself, from the command line, should tell you where the error is.

I based this information on this comment:

Android Studio new project can not run, throwing error

If you are using Grail's Framework, it's simple to resolve lazy initialization exception by using Lazy keyword on specific field in Domain Class.

    static mapping = {
        author lazy: false
    }
}

Take a look at this SO post answer and also look at this basic authentication tutorial from the urllib2 missing manual.

In order for urllib2 basic authentication to work, the http response must contain HTTP code 401 Unauthorized and a key "WWW-Authenticate" with the value "Basic" otherwise, Python won't send your login info, and you will need to either use Requests, or urllib.urlopen(url) with your login in the url, or add a the header like in @Flowpoke's answer.

You can view your error by putting your urlopen in a try block:

try:
    urllib2.urlopen(urllib2.Request(url))
except urllib2.HTTPError, e:
    print e.headers
    print e.headers.has_key('WWW-Authenticate')

I wanted a one-time solution:

ssh -o ServerAliveInterval=60 [email protected]

Stored it in an alias:

alias sshprod='ssh -v -o ServerAliveInterval=60 [email protected]'

Now can connect like this:

me@MyMachine:~$ sshprod

Yes subprocess.Popen(cmd, ..., shell=True) works like a charm. On Windows the .py file extension is recognized, so Python is invoked to process it (on *NIX just the usual shebang). The path environment controls whether things are seen. So the first arg to Popen is just the name of the script.

subprocess.Popen(['myscript.py', 'arg1', ...], ..., shell=True)

If you only need to encode sets, not general Python objects, and want to keep it easily human-readable, a simplified version of Raymond Hettinger's answer can be used:

import json
import collections

class JSONSetEncoder(json.JSONEncoder):
    """Use with json.dumps to allow Python sets to be encoded to JSON

    Example
    -------

    import json

    data = dict(aset=set([1,2,3]))

    encoded = json.dumps(data, cls=JSONSetEncoder)
    decoded = json.loads(encoded, object_hook=json_as_python_set)
    assert data == decoded     # Should assert successfully

    Any object that is matched by isinstance(obj, collections.Set) will
    be encoded, but the decoded value will always be a normal Python set.

    """

    def default(self, obj):
        if isinstance(obj, collections.Set):
            return dict(_set_object=list(obj))
        else:
            return json.JSONEncoder.default(self, obj)

def json_as_python_set(dct):
    """Decode json {'_set_object': [1,2,3]} to set([1,2,3])

    Example
    -------
    decoded = json.loads(encoded, object_hook=json_as_python_set)

    Also see :class:`JSONSetEncoder`

    """
    if '_set_object' in dct:
        return set(dct['_set_object'])
    return dct

Indeed, in the latest version of Spring Data, findOne returns an optional. If you want to retrieve the object from the Optional, you can simply use get() on the Optional. First of all though, a repository should return the optional to a service, which then handles the case in which the optional is empty. afterwards, the service should return the object to the controller.

I doubt that this is what you want but your question is a little bit vague

Dim totalCount As Int32 = DataTable1.Columns.Count * DataTable1.Rows.Count

If all your columns are numeric-columns you might want this:

You could use DataTable.Compute to Sum all values in the column.

 Dim totalCount As Double
 For Each col As DataColumn In DataTable1.Columns
     totalCount += Double.Parse(DataTable1.Compute(String.Format("SUM({0})", col.ColumnName), Nothing).ToString)
 Next

After you've edited your question and added more informations, this should work:

 Dim totalRow = DataTable1.NewRow
 For Each col As DataColumn In DataTable1.Columns
     totalRow(col.ColumnName) = Double.Parse(DataTable1.Compute("SUM(" & col.ColumnName & ")", Nothing).ToString)
 Next
 DataTable1.Rows.Add(totalRow)

Here's a bit more detail to expand on Hooked's answer. When I first read that answer, I missed the instruction to call clf() instead of creating a new figure. clf() on its own doesn't help if you then go and create another figure.

Here's a trivial example that causes the warning:

from matplotlib import pyplot as plt, patches
import os


def main():
    path = 'figures'
    for i in range(21):
        _fig, ax = plt.subplots()
        x = range(3*i)
        y = [n*n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.clf()
    print('Done.')

main()

To avoid the warning, I have to pull the call to subplots() outside the loop. In order to keep seeing the rectangles, I need to switch clf() to cla(). That clears the axis without removing the axis itself.

from matplotlib import pyplot as plt, patches
import os


def main():
    path = 'figures'
    _fig, ax = plt.subplots()
    for i in range(21):
        x = range(3*i)
        y = [n*n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.cla()
    print('Done.')

main()

If you're generating plots in batches, you might have to use both cla() and close(). I ran into a problem where a batch could have more than 20 plots without complaining, but it would complain after 20 batches. I fixed that by using cla() after each plot, and close() after each batch.

from matplotlib import pyplot as plt, patches
import os


def main():
    for i in range(21):
        print('Batch {}'.format(i))
        make_plots('figures')
    print('Done.')


def make_plots(path):
    fig, ax = plt.subplots()
    for i in range(21):
        x = range(3 * i)
        y = [n * n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.cla()
    plt.close(fig)


main()

I measured the performance to see if it was worth reusing the figure within a batch, and this little sample program slowed from 41s to 49s (20% slower) when I just called close() after every plot.

First, unzip the APK and extract the file /META-INF/ANDROID_.RSA (this file may also be CERT.RSA, but there should only be one .RSA file).

Then issue this command:

keytool -printcert -file ANDROID_.RSA

You will get certificate fingerprints like this:

     MD5:  B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:8C:17:DB
     SHA1: 16:59:E7:E3:0C:AA:7A:0D:F2:0D:05:20:12:A8:85:0B:32:C5:4F:68
     Signature algorithm name: SHA1withRSA

Then use the keytool again to print out all the aliases of your signing keystore:

keytool -list -keystore my-signing-key.keystore

You will get a list of aliases and their certificate fingerprint:

android_key, Jan 23, 2010, PrivateKeyEntry,
Certificate fingerprint (MD5): B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:8C:17:DB

Voila! we can now determined the apk has been signed with this keystore, and with the alias 'android_key'.

Keytool is part of Java, so make sure your PATH has Java installation dir in it.

This is an example that works on the AWS Cloud. The scenario is that some machine that booted from autoscaling needs to perform some action on another server, passing the newly spawned instance DNS via SSH

# Get the public DNS of the current machine (AWS specific)
MY_DNS=`curl -s http://169.254.169.254/latest/meta-data/public-hostname`


ssh \
    -o StrictHostKeyChecking=no \
    -i ~/.ssh/id_rsa \
    [email protected] \
<< EOF
cd ~/
echo "Hey I was just SSHed by ${MY_DNS}"
run_other_commands
# Newline is important before final EOF!

EOF

To invoke a dry run:

make -n

This will show what make is attempting to do.

I wasn't satisfied with the accepted answer so I created some scripts to do this for you available on Github. These should help anyone who wants to use git svn clone but doesn't want to clone the entire repository and doesn't want to hunt for a specific revision to clone from in the middle of the history (maybe you're cloning a bunch of repos). Here we can just clone the last N revisions:

Use git svn clone to clone the last 50 revisions

# -u    The SVN URL to clone
# -l    The limit of revisions
# -o    The output directory

./git-svn-cloneback.sh -u https://server/project/trunk -l 50 -o myproj --authors-file=svn-authors.txt

Find the previous N revision from an SVN repo

# -u    The SVN URL to clone
# -l    The limit of revisions

./svn-lookback.sh -u https://server/project/trunk -l 5     

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

It's just a syntax error. You just have to replace j+3 by j=j+3 or j+=3.

Replace this:

var cat = $.jqURL.get('category');
var $dd = $('#cbCategory');
var $options = $('option', $dd);
$options.each(function() {
if ($(this).text() == cat)
    $(this).select(); // This is where my problem is
});

With this:

$('#cbCategory').val(cat);

Calling val() on a select list will automatically select the option with that value, if any.

Set the buttonTint property. For example, android:buttonTint="#99FF33".

I'm posting this answer because the one with the most votes led me astray. To redirect from a servlet, you simply do this:

response.sendRedirect("simpleList.do")

In this particular question, I think @M-D is correctly explaining why the asker is having his problem, but since this is the first result on google when you search for "Redirect from Servlet" I think it's important to have an answer that helps most people, not just the original asker.

Please ensure that your mongo DB is set Automatic and running at Control Panel/Administrative Tools/Services like below. That way you wont have to start mongod.exe manually each time.

There is, in the latest standard, a keyword (export) that would help alleviate this issue, but it isn't implemented in any compiler that I'm aware of, other than Comeau.

See the FAQ-lite about this.

This is because your data sending column type is integer and your are sending a string value to it.

So, the following way worked for me. Try with this one.

$insertQuery = "INSERT INTO workorders VALUES (
                    null,
                    '$priority',
                    '$requestType',
                    '$purchaseOrder',
                    '$nte',
                    '$jobSiteNumber'
                )";

Don't use 'null'. use it as null without single quotes.

You can pass an array as the first AutoFilter argument and use the xlFilterValues operator.

This will display PDF, DOC and DOCX filetypes.

Criteria1:=Array(".pdf", ".doc", ".docx"), Operator:=xlFilterValues

You can use the Screen.PrimaryScreen.Bounds to retrieve the size of the primary monitor (or inspect the Screen object to retrieve all monitors). Use those with MyForms.Bounds to figure out where to place your form.

I had the same issue. Using MySQL 6.1 Workbench.

After a while (2 mins), it just crashed. Reported bug, saved files and reopened. It works now.

I guess I would suggest if that happens again, to immediately save the open scripts, close MySQL and restart it.

This is a slightly modified solution. The Process will be killed when it was idle for at least 1 second. Maybe you should add a timeof of X seconds and call the function from a separate thread.

private void SendToPrinter()
{
  ProcessStartInfo info = new ProcessStartInfo();
  info.Verb = "print";
  info.FileName = @"c:\output.pdf";
  info.CreateNoWindow = true;
  info.WindowStyle = ProcessWindowStyle.Hidden;

  Process p = new Process();
  p.StartInfo = info;
  p.Start();

  long ticks = -1;
  while (ticks != p.TotalProcessorTime.Ticks)
  {
    ticks = p.TotalProcessorTime.Ticks;
    Thread.Sleep(1000);
  }

  if (false == p.CloseMainWindow())
    p.Kill();
}

Installing a 64-bit version of Java will solve the issue. Go to page Java Downloads for All Operating Systems

This is a problem due to the incompatibility of the Java version and the Eclipse version both should be 64 bit if you are using a 64-bit system.

The boost documentation provides a pretty good start example: shared_ptr example (it's actually about a vector of smart pointers) or shared_ptr doc The following answer by Johannes Schaub explains the boost smart pointers pretty well: smart pointers explained

The idea behind(in as few words as possible) ptr_vector is that it handles the deallocation of memory behind the stored pointers for you: let's say you have a vector of pointers as in your example. When quitting the application or leaving the scope in which the vector is defined you'll have to clean up after yourself(you've dynamically allocated ANDgate and ORgate) but just clearing the vector won't do it because the vector is storing the pointers and not the actual objects(it won't destroy but what it contains).

 // if you just do
 G.clear() // will clear the vector but you'll be left with 2 memory leaks
 ...
// to properly clean the vector and the objects behind it
for (std::vector<gate*>::iterator it = G.begin(); it != G.end(); it++)
{
  delete (*it);
}

boost::ptr_vector<> will handle the above for you - meaning it will deallocate the memory behind the pointers it stores.

Generally you don't want to value only the source version (javac -source 1.8 for example) but you want to value both the source and the target version (javac -source 1.8 -target 1.8 for example).
Note that from Java 9, you have a way to convey both information and in a more robust way for cross-compilation compatibility (javac -release 9).
Maven that wraps the javac command provides multiple ways to convey all these JVM standard options.

How to specify the JDK version?

Using maven-compiler-plugin or maven.compiler.source/maven.compiler.target properties to specify the source and the target are equivalent.

<plugins>
    <plugin>    
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
    </plugin>
</plugins>

and

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

are equivalent according to the Maven documentation of the compiler plugin since the <source> and the <target> elements in the compiler configuration use the properties maven.compiler.source and maven.compiler.target if they are defined.

The -source argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.source.

target

The -target argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.target.

About the default values for source and target, note that since the 3.8.0 of the maven compiler, the default values have changed from 1.5 to 1.6.

<release> tag — new way to specify Java version in maven-compiler-plugin 3.6

You can use the release argument :

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <release>9</release>
    </configuration>
</plugin>

You could also declare just the user property maven.compiler.release:

<properties>
    <maven.compiler.release>9</maven.compiler.release>
</properties>

But at this time the last one will not be enough as the maven-compiler-plugin default version you use doesn't rely on a recent enough version.

The Maven release argument conveys release to the Java compiler to access the JVM standard option newly added to Java 9, JEP 247: Compile for Older Platform Versions.

Compiles against the public, supported and documented API for a specific VM version.

This way provides a standard way to specify the same version for the source, the target and the bootstrap JVM options.
Note that specifying the bootstrap is a good practice for cross compilations and it will not hurt if you don't make cross compilations either.

Which is the best way to specify the JDK version?

Java 8 and below

Neither maven.compiler.source/maven.compiler.target properties or using the maven-compiler-plugin is better. It changes nothing in the facts since finally the two ways rely on the same properties and the same mechanism : the maven core compiler plugin.

Well, if you don't need to specify other properties or behavior than Java versions in the compiler plugin, using this way makes more sense as this is more concise:

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Java 9 and later

The release argument (third point) is a way to strongly consider if you want to use the same version for the source and the target.

I tried your code and got a top rounded corner button. I gave the colors as @ffffff and stroke I gave #C0C0C0.

try

1. Giving android : bottomLeftRadius="0.1dp" instead of 0. if its not working
2. Check in what drawable and the emulator's resolution. I created a drawable folder under res and using it. (hdpi, mdpi ldpi) the folder you have this XML. this is my output.

Java does have StringTokenizer API and can be used for this purpose as below.

String test = "This is a test app";
int countOfTokens = new StringTokenizer(test).countTokens();
System.out.println(countOfTokens);

OR

in a single line as below

System.out.println(new StringTokenizer("This is a test app").countTokens());

StringTokenizer supports multiple spaces in the input string, counting only the words trimming unnecessary spaces.

System.out.println(new StringTokenizer("This    is    a test    app").countTokens());

Above line also prints 5

It was probably discussed, but as of CSS3 there is nothing like what you need (see also "Is there a CSS selector for elements containing certain text?"). You will have to use additional markup, like this:

<li><span class="foo">some text</span></li>
<li>some other text</li>

Then refer to it the usual way:

li > span.foo {...}

Short answer: use an unassigned user port

Over achiever's answer - Select and deploy a resource discovery solution. Have the server select a private port dynamically. Have the clients use resource discovery.

The risk that that a server will fail because the port it wants to listen on is not available is real; at least it's happened to me. Another service or a client might get there first.

You can almost totally reduce the risk from a client by avoiding the private ports, which are dynamically handed out to clients.

The risk that from another service is minimal if you use a user port. An unassigned port's risk is only that another service happens to be configured (or dyamically) uses that port. But at least that's probably under your control.

The huge doc with all the port assignments, including User Ports, is here: http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt look for the token Unassigned.

This works for me in Visual Studio 2015.

I copy all DLL files from a folder located in a library folder on the same level as my solution folder into the targetdirectory of the project being built.

Using a relative path from my project directory and going up the folder structure two steps with..\..\lib

MySolutionFolder
....MyProject
Lib

if $(ConfigurationName) == Debug (
xcopy /Y "$(ProjectDir)..\..\lib\*.dll" "$(TargetDir)"
) ELSE (echo "Not Debug mode, no file copy from lib")

In parse_file, take the self argument (just like in __init__). If there's any other context you need then just pass it as additional arguments as usual.

You're looking for the onblur event. Look here, for more details.

If the Path is omitted the file will be saved automaticaly in the current directory. Try something like this:

ActiveWorkbook.SaveAs "Filename.xslx"

The answer given by Nico O is correct. However this doesn't get the desired result on Internet Explorer 10 to 11 and Firefox.

For IE, I found that changing

.flex > div
{
   flex: 1 0 50%;
}

to

.flex > div
{
   flex: 1 0 45%;
}

seems to do the trick. Don't ask me why, I haven't gone any further into this but it might have something to do with how IE renders the border-box or something.

In the case of Firefox I solved it by adding

display: inline-block;

to the items.

When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink], then it should be assigned a name of the property the value of which will be the route it should navigate the user to.

So to fix your issue, replace this routerLink="['/about']" with routerLink="/about" in your HTML.

There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:

<nav class="main-nav>
  <ul 
    class="main-nav__list" 
    ng-sticky 
    addClass="main-sticky-link" 
    [ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
    <li class="main-nav__item" routerLinkActive="active">
      <a class="main-nav__link" routerLink="/">Home</a>
    </li>
    <li class="main-nav__item" routerLinkActive="active"> 
      <a class="main-nav__link" routerLink="/about">About us</a>
    </li>
  </ul>
</nav>

It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>, either in your template provided above or in a parent component.

There's another issue with your AppRoutingModule. You need to export the RouterModule from there so that it is available to your AppModule when it imports it. To fix that, export it from your AppRoutingModule by adding it to the exports array.

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
  { path: 'about', component: AboutComponent },
  { path: 'what', component: WhatwedoComponent },
  { path: 'contacts', component: FooterComponent },
  { path: 'projects', component: ProjectsComponent},
];

@NgModule({
  imports: [
    CommonModule,
    RouterModule.forRoot(routes),
  ],
  exports: [RouterModule],
  declarations: []
})
export class AppRoutingModule { }

So one way is to doExampleEnum valueOfOrdinal = ExampleEnum.values()[ordinal]; which works and its easy, however, as mentioned before, ExampleEnum.values() returns a new cloned array for every call. That can be unnecessarily expensive. We can solve that by caching the array like so ExampleEnum[] values = values(). It is also "dangerous" to allow our cached array to be modified. Someone could write ExampleEnum.values[0] = ExampleEnum.type2; So I would make it private with an accessor method that does not do extra copying.

private enum ExampleEnum{
    type0, type1, type2, type3;
    private static final ExampleEnum[] values = values();
    public static ExampleEnum value(int ord) {
        return values[ord];
    }
}

You would use ExampleEnum.value(ordinal) to get the enum value associated with ordinal

There is no str accessor for datetimes and you can't do dates.astype(str) either, you can call apply and use datetime.strftime:

In [73]:

dates = pd.to_datetime(pd.Series(['20010101', '20010331']), format = '%Y%m%d')
dates.apply(lambda x: x.strftime('%Y-%m-%d'))
Out[73]:
0    2001-01-01
1    2001-03-31
dtype: object

You can change the format of your date strings using whatever you like: strftime() and strptime() Behavior.

Update

As of version 0.17.0 you can do this using dt.strftime

dates.dt.strftime('%Y-%m-%d')

will now work

Using:

apt HelloImpl.java -classpath /sac/tools/thirdparty/jaxws-ri/jaxws-ri-2.1.4/lib/jsr181-api.jar:.

works but it gives me another error, see new question

Try to use

ng g component plainsight/some-name.component.ts

Or try it manually, if you feel more comfortable.

I know it's not the exact answer to this question, but I found this thread after hunting the internet down for an answer. I assume others share that feeling.

This is my variance of the UITapGestureRecognizer which I find reliable and easy to use - just set the delegate of the TextView to the ViewController.

Instead of ViewDidLoad I add the UITapGestureRecognizer when the TextView becomes active for editing:

-(void)textViewDidBeginEditing:(UITextView *)textView{
    _tapRec = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tap:)];

    [self.view addGestureRecognizer: _tapRec];
    NSLog(@"TextView Did begin");
}

When I tap outside the TextView, the view ends editing mode and the UITapGestureRecognizer removes itself so I can continue interacting with other controls in the view.

-(void)tap:(UITapGestureRecognizer *)tapRec{
    [[self view] endEditing: YES];
    [self.view removeGestureRecognizer:tapRec];
    NSLog(@"Tap recognized, tapRec getting removed");
}

I hope this helps. It seems so obvious but I have never seen this solution anywhere on the web - am I doing something wrong?

There are two problems. As in the question, select-string needs to operate on the output string, which can be had from "out-string". Also, select-string doesn't operate linewise on strings that are piped to it. Here is a generic solution

(alias|out-string) -split "`n" | select-string Write 

Another variant is

Assert.assertThat(actual, new Matches(expectedRegex));

Moreover in org.mockito.internal.matchers there are some other interesting matchers, like StartWith, Contains etc.

Use request.args.get(param), for example:

http://10.1.1.1:5000/login?username=alex&password=pw1

@app.route('/login', methods=['GET', 'POST'])
def login():
    username = request.args.get('username')
    print(username)
    password = request.args.get('password')
    print(password)

Here is the referenced link to the code.

I had same issue reported here. I solved the issue moving the mainTest.cpp from a subfolder src/mainTest/ to the main folder src/ I guess this was your problem too.

Here is the example which results in a strange error. Even Google gives no results:

public class ExampleClass {

private static final Pattern dateCreateP = Pattern.compile("???? ??????:\\s*(.+)");
private static final SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss dd.MM.yyyy");

public static void main(String[] args) {
    ExecutorService executor = Executors.newFixedThreadPool(100);
    while (true) {
        executor.submit(new Runnable() {
            @Override
            public void run() {
                workConcurrently();
            }
        });
    }
}

public static void workConcurrently() {
    Matcher matcher = dateCreateP.matcher("???? ??????: 19:30:55 03.05.2015");
    Timestamp startAdvDate = null;
    try {
        if (matcher.find()) {
            String dateCreate = matcher.group(1);
            startAdvDate = new Timestamp(sdf.parse(dateCreate).getTime());
        }
    } catch (Throwable th) {
        th.printStackTrace();
    }
    System.out.print("OK ");
}
}

And result :

OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK OK java.lang.NumberFormatException: For input string: ".201519E.2015192E2"

You should take a look the reference documentation. It's well explained.

In your case, I think you cannot use between because you need to pass two parameters

Between - findByStartDateBetween … where x.startDate between ?1 and ?2

In your case take a look to use a combination of LessThan or LessThanEqual with GreaterThan or GreaterThanEqual

• LessThan/LessThanEqual

LessThan - findByEndLessThan … where x.start< ?1

LessThanEqual findByEndLessThanEqual … where x.start <= ?1

• GreaterThan/GreaterThanEqual

GreaterThan - findByStartGreaterThan … where x.end> ?1

GreaterThanEqual - findByStartGreaterThanEqual … where x.end>= ?1

You can use the operator And and Or to combine both.

Maybe it is easier to convert the Date into the actual integer 20110506105524 and then convert this into a string:

function printDate() {
    var temp = new Date();
    var dateInt =
        ((((temp.getFullYear() * 100 + 
            temp.getMonth() + 1) * 100 + 
           temp.getDate()) * 100 +
          temp.getHours()) * 100 + 
         temp.getMinutes()) * 100 + 
        temp.getSeconds();

    debug ( '' + dateInt );  // convert to String
}

When temp.getFullYear() < 1000 the result will be one (or more) digits shorter.

Caution: this wont work with millisecond precision (i.e. 17 digits) since Number.MAX_SAFE_INTEGER is 9007199254740991 which is only 16 digits.

This worked for me:
If it's a css file tap

<link href="{{ asset('css/app.css') }}" rel="stylesheet" type="text/css" >

If it's an image tap

<link href="{{ asset('css/img/logo.png') }}" rel="stylesheet" type="text/css" >

This is what I came up with. There is an added function to check to see if the int is past the date on which the exceptions were imposed(year$100, year %400). Before 1582 those exceptions weren't around.

import java.util.Scanner;

public class lecture{


public static void main(String[] args) {
    boolean loop=true;
    Scanner console = new Scanner( System.in );
    while (loop){
        System.out.print( "Enter the year: " );

        int year= console.nextInt();
        System.out.println( "The year is a leap year: "+ leapYear(year) );
        System.out.print( "again?: " );
        int again = console.nextInt();
        if (again == 1){
            loop=false;
        }//if
    }
}
public static boolean leapYear ( int year){
    boolean leaped = false;
    if (year%4==0){
        leaped = true;
        if(year>1582){
            if (year%100==0&&year%400!=0){
                leaped=false;
            }
        }
    }//1st if
    return leaped;
}
} 

Just want to point out

Apart from MaxRecivedMessageSize, there are also attributes under ReaderQuotas, you might hit number of items limit instead of size limit. MSDN link is here

On windows 7, find

C:\Users\Simion\AppData\Roaming\Sublime Text 2\Packages\Color Scheme - Default

Find your color scheme file, open it, and find lineHighlight.
Ex:

<key>lineHighlight</key>
<string>#ccc</string>

replace #ccc with your preferred background color.

Just drop the option v.

-v is for verbose. If you don't use it then it won't display:

Muhammad Musavi's comment is the best answer, so here it is surfaced as an actual Answer:

thead/tfoot are automatically repeated on the top and bottom of each page. However, tfoot isn't sticky to the bottom of the last page.

position: fixed in print will repeat on each page, and the footer will stick to the bottom of all pages including the last one - but, it won't create space for its contents.

Combine them:

HTML:

<header>(repeated header)</header>

<table class=paging><thead><tr><td>&nbsp;</td></tr></thead><tbody><tr><td>

(content goes here)

</td></tr></tbody><tfoot><tr><td>&nbsp;</td></tr></tfoot></table>

<footer>(repeated footer)</footer>

CSS:

@page {
    size: letter;
    margin: .5in;
}

@media print {
    table.paging thead td, table.paging tfoot td {
        height: .5in;
    }
}

header, footer {
    width: 100%; height: .5in;
}

header {
    position: absolute;
    top: 0;
}

@media print {
    header, footer {
        position: fixed;
    }
    
    footer {
        bottom: 0;
    }
}

There are a lot of niceties you can add in here, but I've intentionally slashed this to the bare minimum to get a cleanly rendering header and footer, appearing once on-screen and at the top and bottom of every printed page.

As you're using C++ you could use std::string.

'Simple HTML DOM Parser' is a good option for PHP, if your familiar with jQuery or JavaScript selectors then you will find yourself at home.

Find it here

There is also a blog post about it here.

To prove jkp's point that 'anything on one line will probably be helishly complex to understand', I created a one-liner. Please do not mod me down because I understand this is not a solution that you should actually use. It is just for demonstrational purposes.

The idea is to add the values in a one by one, as long as the total times you have added that value does is smaller than the total number of times this value is in a minus the number of times it is in b:

[ value for counter,value in enumerate(a) if a.count(value) >= b.count(value) + a[counter:].count(value) ]

The horror! But perhaps someone can improve on it? Is it even bug free?

Edit: Seeing Devin Jeanpierre comment about using a dictionary datastructure, I came up with this oneliner:

sum([ [value]*count for value,count in {value:a.count(value)-b.count(value) for value in set(a)}.items() ], [])

Better, but still unreadable.

You need to check out a previous version from before you deleted the files. Try git checkout HEAD^ to checkout the last revision.

You can simply download the library which you want to include and copy it to libs folder of your project. Then select that file (in my case it was android-support-v4 library) right click on it and select "Add as Library"

I believe because cases must be constant values, the switch statement does the equivelent of a goto, so based on the value of the variable it jumps to the right case, whereas in the if/then statement it must evaluate each expression.

use strict ; use warnings ; use Cwd 'abs_path';
    sub ResolveMyProductBaseDir { 

        # Start - Resolve the ProductBaseDir
        #resolve the run dir where this scripts is placed
        my $ScriptAbsolutPath = abs_path($0) ; 
        #debug print "\$ScriptAbsolutPath is $ScriptAbsolutPath \n" ;
        $ScriptAbsolutPath =~ m/^(.*)(\\|\/)(.*)\.([a-z]*)/; 
        $RunDir = $1 ; 
        #debug print "\$1 is $1 \n" ;
        #change the \'s to /'s if we are on Windows
        $RunDir =~s/\\/\//gi ; 
        my @DirParts = split ('/' , $RunDir) ; 
        for (my $count=0; $count < 4; $count++) {   pop @DirParts ;     }
        my $ProductBaseDir = join ( '/' , @DirParts ) ; 
        # Stop - Resolve the ProductBaseDir
        #debug print "ResolveMyProductBaseDir $ProductBaseDir is $ProductBaseDir \n" ; 
        return $ProductBaseDir ; 
    } #eof sub

strSearch in this case is probably null (not simply empty).

Try using

String.IsNullOrEmpty(strSearch)

if you are just trying to determine if the string doesn't have any contents.

Similar to the selected answer, a table source can be used, in this case a derived query:

delete from dd
from (
    select top 1 *
    from my_table
) dd

Feel free to add orderbys and conditions.

For the next example, I'll assume that the restriction on 'where' is due to not wanting to select a row based on its values. So assuming that we want to delete a row based on position (in this case the first position):

delete from dd
from (
    select
        *,
        row = row_number() over (order by (select 1))
    from my_table
) dd
where row = 1

Note that the (select 1) makes it the sort order that the tables or indexes are in. You can replace that with a newid to get fairly random rows.

You can also add a partition by to delete the top row of each color, for example.

For what it is worth, I have seen a lot of users recommend iterating through INSERT statements instead of building out as a single string query as the selected answer did. I decided to run a simple test with just two fields and a very basic insert statement:

<?php
require('conn.php');

$fname = 'J';
$lname = 'M';

$time_start = microtime(true);
$stmt = $db->prepare('INSERT INTO table (FirstName, LastName) VALUES (:fname, :lname)');

for($i = 1; $i <= 10; $i++ )  {
    $stmt->bindParam(':fname', $fname);
    $stmt->bindParam(':lname', $lname);
    $stmt->execute();

    $fname .= 'O';
    $lname .= 'A';
}


$time_end = microtime(true);
$time = $time_end - $time_start;

echo "Completed in ". $time ." seconds <hr>";

$fname2 = 'J';
$lname2 = 'M';

$time_start2 = microtime(true);
$qry = 'INSERT INTO table (FirstName, LastName) VALUES ';
$qry .= "(?,?), ";
$qry .= "(?,?), ";
$qry .= "(?,?), ";
$qry .= "(?,?), ";
$qry .= "(?,?), ";
$qry .= "(?,?), ";
$qry .= "(?,?), ";
$qry .= "(?,?), ";
$qry .= "(?,?), ";
$qry .= "(?,?)";

$stmt2 = $db->prepare($qry);
$values = array();

for($j = 1; $j<=10; $j++) {
    $values2 = array($fname2, $lname2);
    $values = array_merge($values,$values2);

    $fname2 .= 'O';
    $lname2 .= 'A';
}

$stmt2->execute($values);

$time_end2 = microtime(true);
$time2 = $time_end2 - $time_start2;

echo "Completed in ". $time2 ." seconds <hr>";
?>

While the overall query itself took milliseconds or less, the latter (single string) query was consistently 8 times faster or more. If this was built out to say reflect an import of thousands of rows on many more columns, the difference could be enormous.

I solved this problem by setting UseCookies in web.config.

  <system.web>
    <sessionState cookieless="UseCookies" />

and setting enableVersionHeader

  <system.web>
    <httpRuntime targetFramework="4.5.1" enableVersionHeader="false" executionTimeout="1200" shutdownTimeout="1200" maxRequestLength="103424" />

This is what I found after a more specific Google search than just UTF-8 encode/decode. so for those who are looking for a converting library to convert between encodings, here you go.

https://github.com/inexorabletash/text-encoding

var uint8array = new TextEncoder().encode(str);
var str = new TextDecoder(encoding).decode(uint8array);

Paste from repo readme

All encodings from the Encoding specification are supported:

utf-8 ibm866 iso-8859-2 iso-8859-3 iso-8859-4 iso-8859-5 iso-8859-6 iso-8859-7 iso-8859-8 iso-8859-8-i iso-8859-10 iso-8859-13 iso-8859-14 iso-8859-15 iso-8859-16 koi8-r koi8-u macintosh windows-874 windows-1250 windows-1251 windows-1252 windows-1253 windows-1254 windows-1255 windows-1256 windows-1257 windows-1258 x-mac-cyrillic gb18030 hz-gb-2312 big5 euc-jp iso-2022-jp shift_jis euc-kr replacement utf-16be utf-16le x-user-defined

(Some encodings may be supported under other names, e.g. ascii, iso-8859-1, etc. See Encoding for additional labels for each encoding.)

The callbacks attached to done() will be fired when the deferred is resolved. The callbacks attached to fail() will be fired when the deferred is rejected.

Prior to jQuery 1.8, then() was just syntactic sugar:

promise.then( doneCallback, failCallback )
// was equivalent to
promise.done( doneCallback ).fail( failCallback )

As of 1.8, then() is an alias for pipe() and returns a new promise, see here for more information on pipe().

success() and error() are only available on the jqXHR object returned by a call to ajax(). They are simple aliases for done() and fail() respectively:

jqXHR.done === jqXHR.success
jqXHR.fail === jqXHR.error

Also, done() is not limited to a single callback and will filter out non-functions (though there is a bug with strings in version 1.8 that should be fixed in 1.8.1):

// this will add fn1 to 7 to the deferred's internal callback list
// (true, 56 and "omg" will be ignored)
promise.done( fn1, fn2, true, [ fn3, [ fn4, 56, fn5 ], "omg", fn6 ], fn7 );

Same goes for fail().

Try this:

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setTitle("Confirm");
builder.setMessage("Are you sure?");

builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which) {
        // Do nothing but close the dialog

        dialog.dismiss();
    }
});

builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {

        // Do nothing
        dialog.dismiss();
    }
});

AlertDialog alert = builder.create();
alert.show();

In process all threads share system resource like heap Memory etc. while Thread has its own stack

So your ans should be heap memory which all threads share for a process.

i wanted to ask if Android Devices uses the network time protocol (ntp) to synchronize the time.

For general time synchronization, devices with telephony capability, where the wireless provider provides NITZ information, will use NITZ. My understanding is that NTP is used in other circumstances: NITZ-free wireless providers, WiFi-only, etc.

Your cited blog post suggests another circumstance: on-demand time synchronization in support of GPS. That is certainly conceivable, though I do not know whether it is used or not.

Here Is working fiddle

The simplest way I've made is :

1. Make repository on github with your dataset
2. Clone Your repository with ! git clone --recursive [GITHUB LINK REPO]
3. Find where is your data ( !ls command )
4. Open file with pandas as You do it in normal jupyter notebook.

I found the following summary very useful: http://www.techrepublic.com/article/configure-vi-for-java-application-development/5054618. The description of :make was for ant not maven, but otherwise a nice summary.

Don't use in-line JavaScript, separate your behaviour from your data and it gets much easier to handle. I'd suggest the following:

var table = document.getElementById('tableID'),
    cells = table.getElementsByTagName('td');

for (var i=0,len=cells.length; i<len; i++){
    cells[i].onclick = function(){
        console.log(this.innerHTML);
        /* if you know it's going to be numeric:
        console.log(parseInt(this.innerHTML),10);
        */
    }
}

var table = document.getElementById('tableID'),_x000D_
  cells = table.getElementsByTagName('td');_x000D_
_x000D_
for (var i = 0, len = cells.length; i < len; i++) {_x000D_

A revised approach, in response to the comment (below):

You're missing a semicolon. Also, don't make functions within a loop.

This revision binds a (single) named function as the click event-handler of the multiple <td> elements, and avoids the unnecessary overhead of creating multiple anonymous functions within a loop (which is poor practice due to repetition and the impact on performance, due to memory usage):

function logText() {
  // 'this' is automatically passed to the named
  // function via the use of addEventListener()
  // (later):
  console.log(this.textContent);
}

// using a CSS Selector, with document.querySelectorAll()
// to get a NodeList of <td> elements within the #tableID element:
var cells = document.querySelectorAll('#tableID td');

// iterating over the array-like NodeList, using
// Array.prototype.forEach() and Function.prototype.call():
Array.prototype.forEach.call(cells, function(td) {
  // the first argument of the anonymous function (here: 'td')
  // is the element of the array over which we're iterating.

  // adding an event-handler (the function logText) to handle
  // the click events on the <td> elements:
  td.addEventListener('click', logText);
});

function logText() {_x000D_
  console.log(this.textContent);_x000D_
}_x000D_
_x000D_
var cells = document.querySelectorAll('#tableID td');_x000D_

SharedPreferences are stored in an xml file in the app data folder, i.e.

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml

or the default preferences at:

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PACKAGE_NAME_preferences.xml

SharedPreferences added during runtime are not stored in the Eclipse project.

Note: Accessing /data/data/<package_name> requires superuser privileges

Also with Apache StringUtils.strip():

 StringUtils.strip(null, *)          = null
 StringUtils.strip("", *)            = ""
 StringUtils.strip("abc", null)      = "abc"
 StringUtils.strip("  abc", null)    = "abc"
 StringUtils.strip("abc  ", null)    = "abc"
 StringUtils.strip(" abc ", null)    = "abc"
 StringUtils.strip("  abcyx", "xyz") = "  abc"

So,

final String SchrodingersQuotedString = "may or may not be quoted";
StringUtils.strip(SchrodingersQuotedString, "\""); //quoted no more

This method works both with quoted and unquoted strings as shown in my example. The only downside is, it will not look for strictly matched quotes, only leading and trailing quote characters (ie. no distinction between "partially and "fully" quoted strings).

If you combine the answers above, finally a pom.xml that configured for UTF-8 should seem like that.

Use:

DefaultTableModel model = new DefaultTableModel(); 
JTable table = new JTable(model); 

// Create a couple of columns 
model.addColumn("Col1"); 
model.addColumn("Col2"); 

// Append a row 
model.addRow(new Object[]{"v1", "v2"});

One thing you could do is to have the following snippet in your Workbook:

Sub SaveCodeModules()

'This code Exports all VBA modules
Dim i%, sName$

    With ThisWorkbook.VBProject
        For i% = 1 To .VBComponents.Count
            If .VBComponents(i%).CodeModule.CountOfLines > 0 Then
                sName$ = .VBComponents(i%).CodeModule.Name
                .VBComponents(i%).Export "C:\Code\" & sName$ & ".vba"
            End If
        Next i
    End With
End Sub

I found this snippet on the Internet.

Afterwards, you could use Subversion to maintain version control. For example by using the command line interface of Subversion with the 'shell' command within VBA. That would do it. I'm even thinking of doing this myself :)

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack), you just need to find an output of the hash function that is equal to the hash of a valid password (thus "collision"). Finding a collision using a birthday attack takes O(2^(n/2)) time, where n is the output length of the hash function in bits.

SHA-2 has an output size of 512 bits, so finding a collision would take O(2^256) time. Given there are no clever attacks on the algorithm itself (currently none are known for the SHA-2 hash family) this is what it takes to break the algorithm.

To get a feeling for what 2^256 actually means: currently it is believed that the number of atoms in the (entire!!!) universe is roughly 10^80 which is roughly 2^266. Assuming 32 byte input (which is reasonable for your case - 20 bytes salt + 12 bytes password) my machine takes ~0,22s (~2^-2s) for 65536 (=2^16) computations. So 2^256 computations would be done in 2^240 * 2^16 computations which would take

2^240 * 2^-2 = 2^238 ~ 10^72s ~ 3,17 * 10^64 years

Even calling this millions of years is ridiculous. And it doesn't get much better with the fastest hardware on the planet computing thousands of hashes in parallel. No human technology will be able to crunch this number into something acceptable.

So forget brute-forcing SHA-256 here. Your next question was about dictionary words. To retrieve such weak passwords rainbow tables were used traditionally. A rainbow table is generally just a table of precomputed hash values, the idea is if you were able to precompute and store every possible hash along with its input, then it would take you O(1) to look up a given hash and retrieve a valid preimage for it. Of course this is not possible in practice since there's no storage device that could store such enormous amounts of data. This dilemma is known as memory-time tradeoff. As you are only able to store so many values typical rainbow tables include some form of hash chaining with intermediary reduction functions (this is explained in detail in the Wikipedia article) to save on space by giving up a bit of savings in time.

Salts were a countermeasure to make such rainbow tables infeasible. To discourage attackers from precomputing a table for a specific salt it is recommended to apply per-user salt values. However, since users do not use secure, completely random passwords, it is still surprising how successful you can get if the salt is known and you just iterate over a large dictionary of common passwords in a simple trial and error scheme. The relationship between natural language and randomness is expressed as entropy. Typical password choices are generally of low entropy, whereas completely random values would contain a maximum of entropy.

The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords. If you google for them, you will end up finding torrent links for such password databases, often in the gigabyte size category. Being successful with such a tool is usually in the range of minutes to days if the attacker is not restricted in any way.

That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5 and you should enforce a waiting period for a given user before they may retry entering their password. A good scheme is to start with 0.5s and then doubling that time for each failed attempt. In most cases users don't notice this and don't fail much more often than three times on average. But it will significantly slow down any malicious outsider trying to attack your application.

Add -m to the recommended answer above to prune empty directories.

Here's another way of transferring large tables. I've just transferred 105 million rows between two servers using this. Quite quick too.

1. Right-click on the database and choose Tasks/Export Data.
2. A wizard will take you through the steps but you choosing your SQL server client as the data source and target will allow you to select the database and table(s) you wish to transfer.

For more information, see https://www.mssqltips.com/sqlservertutorial/202/simple-way-to-export-data-from-sql-server/

We can use Stack and push "i" into the stack every time we encounter the condition "arr[i]==value"

Check this:

static void getindex(int arr[], int value)
{
    Stack<Integer>st= new Stack<Integer>();
    int n= arr.length;
    for(int i=n-1; i>=0 ;i--)
    {
        if(arr[i]==value)
        {
            st.push(i);
        }
    }   
    while(!st.isEmpty())
    {
        System.out.println(st.peek()+" ");
        st.pop(); 
    }
}

My solution is basically the same as dickoa's but a little easier to interpret:

data(mtcars)
n = nrow(mtcars)
trainIndex = sample(1:n, size = round(0.7*n), replace=FALSE)
train = mtcars[trainIndex ,]
test = mtcars[-trainIndex ,]

It's creating the file in the same directory as your script. Try this instead.

$content = "some text here";
$fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/myText.txt","wb");
fwrite($fp,$content);
fclose($fp);

Use background-size for that purpose:

background-size: 100% 100%;

As stated in the JQuery documentation

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

If you don't want to install MySQL workbench, and are looking for an online tool, this might help: http://ondras.zarovi.cz/sql/demo/

I use it quite often to create simple DB schemas for various apps I build.

Http 415 Media Unsupported is responded back only when the content type header you are providing is not supported by the application.

With POSTMAN, the Content-type header you are sending is Content type 'multipart/form-data not application/json. While in the ajax code you are setting it correctly to application/json. Pass the correct Content-type header in POSTMAN and it will work.

Backout restores or undoes our changes. The way it does this is that, P4 undoes the changes in a changelist (default or new) on our local workspace. We then have to submit/commit this backedout changelist as we do other changeslists. The second part is important here, as it doesn't automatically backout the changelist on the server, we have to submit the backedout changelist (which makes sense after you do it, but i was initially assuming it does that automatically).

As pointed by others, Rollback has greater powers - It can restore changes to a specific date, changelist or a revision#

This is working code:

<html>
  <body bgcolor=cyan>
    <img src ="backgr1.JPG" id="my" width="310" height="392" style="position: absolute; top:92px; left:375px; visibility:hidden"/>
    <script type="text/javascript">
      function tend() {
        document.getElementById('my').style.visibility='visible';
      }
      function tn() {
        document.getElementById('my').style.visibility='hidden';
      }
    </script>
    <input type="button" onclick="tend()" value="back">
    <input type="button" onclick="tn()" value="close">
  </body>
</html>

use DateTime.ParseExact

string strDate = "24/01/2013";
DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", null)

• DateTime.ParseExact

null will use the current culture, which is somewhat dangerous. Try to supply a specific culture

DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", CultureInfo.InvariantCulture)

I solve this problem by change the first letter case to upper. Make sure ''from Crypto.Cipher import AES'' not ''from crypto.Cipher import AES''.

NDepend was already mentioned by Jesse (if you analyze .NET code) but let's explain exactly how it can help.

Is there a program/script that can scan an executable for DLL dependencies or execute the program in a "clean" DLL-free environment for testing to prevent these oops situations?

In the NDepend Project Properties panel, you can define what application assemblies to analyze (in green) and NDepend will infer Third-Party assemblies used by application ones (in blue). A list of directories where to search application and third-party assemblies is provided.

If a third-party assembly is not found in these directories, it will be in error mode. For example, if I remove the .NET Fx directory C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319, I can see that .NET Fx third-party assemblies are not resolved:

Disclaimer: I work for NDepend

This is just a suggestion, but what I like to do while I'm coding sometimes is to Invert the colors of my Screen. On a Mac it's Ctrl-Cmd-Alt->8 and it inverts the colors.

Haven't personally tried these in Idea10, but it worked on Idea9. http://devnet.jetbrains.net/docs/DOC-1154

@dev-nish Your code works with little tweaks in them. make the

const navigationExtras: NavigationExtras = {
  state: {
    transd: 'TRANS001',
    workQueue: false,
    services: 10,
    code: '003'
  }
};

into

let navigationExtras: NavigationExtras = {
  state: {
    transd: '',
    workQueue: ,
    services: ,
    code: ''
  }
};

then if you want to specifically sent a type of data, for example, JSON as a result of a form fill you can send the data in the same way as explained before.

paste your .html file in assets folder of your project folder. and create an xml file in layout folder with the fol code: my.xml:

<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/webview"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
    />

add fol code in activity

setContentView(R.layout.my);
    WebView mWebView = null;
    mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.loadUrl("file:///android_asset/new.html"); //new.html is html file name.

Since using the @Value("new Long("myconfig")") with cast could throw error on startup if the config is not found or if not in the same expected number format

We used the following approach and is working as expected with fail safe check.

@Configuration()
public class MyConfiguration {

   Long DEFAULT_MAX_IDLE_TIMEOUT = 5l;

   @Value("db.timeoutInString")
   private String timeout;

   public Long getTimout() {
        final Long timoutVal = StringUtil.parseLong(timeout);
        if (null == timoutVal) {
            return DEFAULT_MAX_IDLE_TIMEOUT;
        }
        return timoutVal;
    }
}
   

A of couple things that need to happen...

1. The view controller needs to extend the type UITableViewDelegate

2. The view controller needs to include the didSelectRowAt function.

3. The table view must have the view controller assigned as its delegate.

Below is one place where assigning the delegate could take place (within the view controller).

override func loadView() {
    tableView.dataSource = self
    tableView.delegate = self
    view = tableView
}

And a simple implementation of the didSelectRowAt function.

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    print("row: \(indexPath.row)")
}

You can try in two ways. The detail is in this link.

1) Via pip

pip install --upgrade certifi

2) If it doesn't work, try to run a Cerificates.command that comes bundled with Python 3.* for Mac:(Go to your python installation location and double click the file)

open /Applications/Python\ 3.*/Install\ Certificates.command

This thread is rather old but I have determined an option that could prove useful.

Instead of using the Java AudioStream library you could use an external program like Windows Media Player or VLC and run it with a console command through Java.

String command = "\"C:/Program Files (x86)/Windows Media Player/wmplayer.exe\" \"C:/song.mp3\"";
try {
    Process p = Runtime.getRuntime().exec(command);
catch (IOException e) {
    e.printStackTrace();
}

This will also create a separate process that can be controlled it the program.

p.destroy();

Of course this will take longer to execute than using an internal library but there may be programs that can start up faster and possibly without a GUI given certain console commands.

If time is not of the essence then this is useful.

I'll mention the more obvious way of dealing with duplicates in lists. In terms of complexity, dictionaries are the way to go because each lookup is O(1). You can be more clever if you're only interested in duplicates...

my_list = [1,1,2,3,4,5,5]
my_dict = {}
for (ind,elem) in enumerate(my_list):
    if elem in my_dict:
        my_dict[elem].append(ind)
    else:
        my_dict.update({elem:[ind]})

for key,value in my_dict.iteritems():
    if len(value) > 1:
        print "key(%s) has indices (%s)" %(key,value)

which prints the following:

key(1) has indices ([0, 1])
key(5) has indices ([5, 6])

int num1=5,num2=5

Declaring and assigning variables in the same statement.

These are the necersary imports:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

And this is a method that will allow you to read from a File by passing it the filename as a parameter like this: readFile("yourFile.txt");

String readFile(String fileName) throws IOException {
    BufferedReader br = new BufferedReader(new FileReader(fileName));
    try {
        StringBuilder sb = new StringBuilder();
        String line = br.readLine();

        while (line != null) {
            sb.append(line);
            sb.append("\n");
            line = br.readLine();
        }
        return sb.toString();
    } finally {
        br.close();
    }
}

In case you want a single line of code:

String date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(Calendar.getInstance().getTime());

The result is "2016-09-25 16:50:34"

Using Dollar should be as simple as:

// "0123456789" + "ABCDE...Z"
String validCharacters = $('0', '9').join() + $('A', 'Z').join();

String randomString(int length) {
    return $(validCharacters).shuffle().slice(length).toString();
}

@Test
public void buildFiveRandomStrings() {
    for (int i : $(5)) {
        System.out.println(randomString(12));
    }
}

It outputs something like this:

DKL1SBH9UJWC
JH7P0IT21EA5
5DTI72EO6SFU
HQUMJTEBNF7Y
1HCR6SKYWGT7

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

Those errors :

"CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage"

means you haven't installed mingw32-base.

Go to http://sourceforge.net/projects/mingw/files/latest/download?source=files

and then make sure you select "mingw32-base"

Make sure you set up environment variables correctly in PATH section. "C:\MinGW\bin"

After that open CMake and Select Installation --> Delete Cache.

And click configure button again. I solved the problem this way, hope you solve the problem.

I have exactly the same issue. I ran a couple of virtual hosts on my local machine for developing.

First, I changed /etc/apache2/conf-available/php5-fpm.conf. I replaced every

Order Deny,Allow
Deny from all

to

Require all granted

The configuration has to be enabled by a2enconf php5-fpm. I did the same with my virtual hosts configurations and made the replacements.

I think this is not advised for security reasons, but as long as I use my server for local purposes only I can live with it.

I've spent the last few months messing around with Gemfiles and Gemfile.locks a lot whilst building an automated dependency update tool¹. The below is far from definitive, but it's a good starting point for understanding the Gemfile.lock format. You might also want to check out the source code for Bundler's lockfile parser.

You'll find the following headings in a lockfile generated by Bundler 1.x:

GEM (optional but very common)

These are dependencies sourced from a Rubygems server. That may be the main Rubygems index, at Rubygems.org, or it may be a custom index, such as those available from Gemfury and others. Within this section you'll see:

• remote: one or more lines specifying the location of the Rubygems index(es)
• specs: a list of dependencies, with their version number, and the constraints on any subdependencies

GIT (optional)

These are dependencies sourced from a given git remote. You'll see a different one of these sections for each git remote, and within each section you'll see:

• remote: the git remote. E.g., [email protected]:rails/rails
• revision: the commit reference the Gemfile.lock is locked to
• tag: (optional) the tag specified in the Gemfile
• specs: the git dependency found at this remote, with its version number, and the constraints on any subdependencies

PATH (optional)

These are dependencies sourced from a given path, provided in the Gemfile. You'll see a different one of these sections for each path dependency, and within each section you'll see:

• remote: the path. E.g., plugins/vendored-dependency
• specs: the git dependency found at this remote, with its version number, and the constraints on any subdependencies

PLATFORMS

The Ruby platform the Gemfile.lock was generated against. If any dependencies in the Gemfile specify a platform then they will only be included in the Gemfile.lock when the lockfile is generated on that platform (e.g., through an install).

DEPENDENCIES

A list of the dependencies which are specified in the Gemfile, along with the version constraint specified there.

Dependencies specified with a source other than the main Rubygems index (e.g., git dependencies, path-based, dependencies) have a ! which means they are "pinned" to that source² (although one must sometimes look in the Gemfile to determine in).

RUBY VERSION (optional)

The Ruby version specified in the Gemfile, when this Gemfile.lock was created. If a Ruby version is specified in a .ruby_version file instead this section will not be present (as Bundler will consider the Gemfile / Gemfile.lock agnostic to the installer's Ruby version).

BUNDLED WITH (Bundler >= v1.10.x)

The version of Bundler used to create the Gemfile.lock. Used to remind installers to update their version of Bundler, if it is older than the version that created the file.

PLUGIN SOURCE (optional and very rare)

In theory, a Gemfile can specify Bundler plugins, as well as gems³, which would then be listed here. In practice, I'm not aware of any available plugins, as of July 2017. This part of Bundler is still under active development!

Thanks for that info on the ControlToValidate LukeH!

What I was trying to do in my code was to only ensure that some text field A has some text in the field when text field B has a particular value. Otherwise, A can be blank or whatever else. Getting rid of the ControlToValidate="A" in my mark up fixed the issue for me.

Cheers!

As an alternative representation you could use

[in] '%s' % hex(15)
[out]'0xf'

It's not how they work. You "start" a marquee style progress bar by making it visible, you stop it by hiding it. You could change the Style property.

This is the best format. Works in all of those cases:

String.Format( "{0:#,##0.##}", 0 ); // 0
String.Format( "{0:#,##0.##}", 0.5 ); // 0.5 - some of the formats above fail here. 
String.Format( "{0:#,##0.##}", 12314 ); // 12,314
String.Format( "{0:#,##0.##}", 12314.23123 ); // 12,314.23
String.Format( "{0:#,##0.##}", 12314.2 ); // 12,314.2
String.Format( "{0:#,##0.##}", 1231412314.2 ); // 1,231,412,314.2

I know that this is about matplotlib, but using pandas and seaborn can save you a lot of time:

df = pd.DataFrame(zip(x*3, ["y"]*3+["z"]*3+["k"]*3, y+z+k), columns=["time", "kind", "data"])
plt.figure(figsize=(10, 6))
sns.barplot(x="time", hue="kind", y="data", data=df)
plt.show()

Relatable post

Those pesky black dots you are referencing to are called bullets.

They are pretty simple to remove, just add this line to your css:

ul {
    list-style-type: none;
}

Hope this helps

I had a similar problem.

When I googled, I came across the blog post Install Watch Command on Mac OS X recently. This is not exactly 'installing software', but simply getting the binary for the 'watch' command.

simple solution from my end is to keep another Table with border and insert your table in the outer table.

<table border="1">
<tr>
    <td>
        <table border="0">
            <tr>
                <td>one</td>
                <td>two</td>
            </tr>
            <tr>
                <td>one</td>
                <td>two</td>
            </tr>
        </table>
    </td>
</tr>

</table>

Short answer: Not likely.

Long answer: Your compiler has an optimizer in it that knows how to multiply as quickly as your target processor architecture is capable. Your best bet is to tell the compiler your intent clearly (i.e. i*2 rather than i << 1) and let it decide what the fastest assembly/machine code sequence is. It's even possible that the processor itself has implemented the multiply instruction as a sequence of shifts & adds in microcode.

Bottom line--don't spend a lot of time worrying about this. If you mean to shift, shift. If you mean to multiply, multiply. Do what is semantically clearest--your coworkers will thank you later. Or, more likely, curse you later if you do otherwise.

(n & 1) will check if 'n' is odd or even, this is similar to (n%2).

1. In case 'n' is odd (n & 1) will return true/1;

2. Else it will return back false/0;

The '>>' in (n>>=1) is a bitwise operator called "Right shift", this operator will modify the value of 'n', the formula is:

(n >>= m) => (n = n>>m) => (n = n/2^m)

Go through GeeksforGeek's article on "Bitwise Operator's", recommended!

This is what I am using for learning sql: employees-db

this is a sample database with an integrated test suite, used to test your applications and database servers

3rd party edit

According to launchpad.net the database has moved to github.

The database contains about 300,000 employee records with 2.8 million salary entries. The export data is 167 MB, which is not huge, but heavy enough to be non-trivial for testing.

The data was generated, and as such there are inconsistencies and subtle problems. Rather than removing them, we decided to leave the contents untouched, and use these issues as data cleaning exercises.

Another option I had to use with VSTS:

git config credential.modalprompt false --global

You are trying to store a Unicode codepoint \u201c using an encoding ISO-8859-1 / Latin-1 that can't describe that codepoint. Either you might need to alter the database to use utf-8, and store the string data using an appropriate encoding, or you might want to sanitise your inputs prior to storing the content; i.e. using something like Sam Ruby's excellent i18n guide. That talks about the issues that windows-1252 can cause, and suggests how to process it, plus links to sample code!

It seems to me that all other answers here (so far) fail to address the race-condition that occurs with their proposed solutions.

Any code where you first check for the files existence, and then, a few lines later in your program, you create it, runs the risk of the file being created while you weren't looking and causing you problems (or you causing the owner of "that other file" problems).

If you want to avoid this sort of thing, I would suggest something like the following (untested):

import os

def open_if_not_exists(filename):
    try:
        fd = os.open(filename, os.O_CREAT | os.O_EXCL | os.O_WRONLY)
    except OSError, e:
        if e.errno == 17:
            print e
            return None
        else:
            raise
    else:
        return os.fdopen(fd, 'w')

This should open your file for writing if it doesn't exist already, and return a file-object. If it does exists, it will print "Ooops" and return None (untested, and based solely on reading the python documentation, so might not be 100% correct).

Keyguard basically refers to the code that handles the unlocking of the phone. it's like the keypad lock on your nokia phone a few years back just with the utility on a touchscreen.

you can find more info it you look in android/app or com\android\internal\policy\impl

Good Luck !

There is lots of information about the Fibonacci Sequence on wikipedia and on wolfram. A lot more than you may need. Anyway it is a good thing to learn how to use these resources to find (quickly if possible) what you need.

Write Fib sequence formula to infinite

In math, it's given in a recursive form:

In programming, infinite doesn't exist. You can use a recursive form translating the math form directly in your language, for example in Python it becomes:

def F(n):
    if n == 0: return 0
    elif n == 1: return 1
    else: return F(n-1)+F(n-2)

Try it in your favourite language and see that this form requires a lot of time as n gets bigger. In fact, this is O(2ⁿ) in time.

Go on on the sites I linked to you and will see this (on wolfram):

This one is pretty easy to implement and very, very fast to compute, in Python:

from math import sqrt
def F(n):
    return ((1+sqrt(5))**n-(1-sqrt(5))**n)/(2**n*sqrt(5))

An other way to do it is following the definition (from wikipedia):

The first number of the sequence is 0, the second number is 1, and each subsequent number is equal to the sum of the previous two numbers of the sequence itself, yielding the sequence 0, 1, 1, 2, 3, 5, 8, etc.

If your language supports iterators you may do something like:

def F():
    a,b = 0,1
    while True:
        yield a
        a, b = b, a + b

Display startNumber to endNumber only from Fib sequence.

Once you know how to generate Fibonacci Numbers you just have to cycle trough the numbers and check if they verify the given conditions.

Suppose now you wrote a f(n) that returns the n-th term of the Fibonacci Sequence (like the one with sqrt(5) )

In most languages you can do something like:

def SubFib(startNumber, endNumber):
    n = 0
    cur = f(n)
    while cur <= endNumber:
        if startNumber <= cur:
            print cur
        n += 1
        cur = f(n)

In python I'd use the iterator form and go for:

def SubFib(startNumber, endNumber):
    for cur in F():
        if cur > endNumber: return
        if cur >= startNumber:
            yield cur

for i in SubFib(10, 200):
    print i

My hint is to learn to read what you need. Project Euler (google for it) will train you to do so :P Good luck and have fun!

You can use npm shrinkwrap functionality, in order to override any dependency or sub-dependency.

I've just done this in a grunt project of ours. We needed a newer version of connect, since 2.7.3. was causing trouble for us. So I created a file named npm-shrinkwrap.json:

{
  "dependencies": {
    "grunt-contrib-connect": {
      "version": "0.3.0",
      "from": "[email protected]",
      "dependencies": {
        "connect": {
          "version": "2.8.1",
          "from": "connect@~2.7.3"
        }
      }
    }
  }
}

npm should automatically pick it up while doing the install for the project.

(See: https://nodejs.org/en/blog/npm/managing-node-js-dependencies-with-shrinkwrap/)

If you don't want to import the calendar module, a simple two-step function can also be:

import datetime

def last_day_of_month(any_day):
    # this will never fail
    # get close to the end of the month for any day, and add 4 days 'over'
    next_month = any_day.replace(day=28) + datetime.timedelta(days=4)
    # subtract the number of remaining 'overage' days to get last day of current month, or said programattically said, the previous day of the first of next month
    return next_month - datetime.timedelta(days=next_month.day)

Outputs:

>>> for month in range(1, 13):
...     print last_day_of_month(datetime.date(2012, month, 1))
...
2012-01-31
2012-02-29
2012-03-31
2012-04-30
2012-05-31
2012-06-30
2012-07-31
2012-08-31
2012-09-30
2012-10-31
2012-11-30
2012-12-31

If you need to retrieve more columns other than columns which are in group by then you can consider below query. Check it once whether it is performing well or not.

SELECT 
a.[CUSTOMER ID], 
a.[NAME], 
(select SUM(b.[AMOUNT]) from INV_DATA b
where b.[CUSTOMER ID] = a.[CUSTOMER ID]
GROUP BY b.[CUSTOMER ID]) AS [TOTAL AMOUNT]
FROM RES_DATA a

Use this one:

Get-ChildItem -Path \\server\share\folder\ -Recurse -Force | where {$_.Attributes -like '*Directory*'} | Export-Csv -Path C:\Temp\Export.csv -Encoding "Unicode" -Delimiter ";"

If I understood the question correctly, you can use the slicing notation to keep everything except the last item:

record = record[:-1]

But a better way is to delete the item directly:

del record[-1]

Note 1: Note that using record = record[:-1] does not really remove the last element, but assign the sublist to record. This makes a difference if you run it inside a function and record is a parameter. With record = record[:-1] the original list (outside the function) is unchanged, with del record[-1] or record.pop() the list is changed. (as stated by @pltrdy in the comments)

Note 2: The code could use some Python idioms. I highly recommend reading this:
Code Like a Pythonista: Idiomatic Python (via wayback machine archive).

If you want to change your number into a list of those numbers, I would first cast it to a string, then casting it to a list will naturally break on each character:

[int(x) for x in str(n)]

If you don't want to use LINQ, then:

int index;
for (int i = 0; i < myList.Count; i++)
{
    if (myList[i].Prop == oProp)
    {
       index = i;
       break;
    }
}

this way you are iterating list only once.

Since US-ASCII characters are in the byte range of 0x00–0x7F (0–127):

xxx[\x00-\x7F]+xxx

You need this include:

#include <sstream>

Thanks everyone especially szatmary as this is a complex question and has many layers to it, all which have to be working before you can stream live video. To clarify my original question and HTML5 video use vs flash - my use case has a strong preference for HTML5 because it is generic, easy to implement on the client and the future. Flash is a distant second best so lets stick with HTML5 for this question.

I learnt a lot through this exercise and agree live streaming is much harder than VOD (which works well with HTML5 video). But I did get this to work satisfactorily for my use case and the solution worked out to be very simple, after chasing down more complex options like MSE, flash, elaborate buffering schemes in Node. The problem was that FFMPEG was corrupting the fragmented MP4 and I had to tune the FFMPEG parameters, and the standard node stream pipe redirection over http that I used originally was all that was needed.

In MP4 there is a 'fragmentation' option that breaks the mp4 into much smaller fragments which has its own index and makes the mp4 live streaming option viable. But not possible to seek back into the stream (OK for my use case), and later versions of FFMPEG support fragmentation.

Note timing can be a problem, and with my solution I have a lag of between 2 and 6 seconds caused by a combination of the remuxing (effectively FFMPEG has to receive the live stream, remux it then send it to node for serving over HTTP). Not much can be done about this, however in Chrome the video does try to catch up as much as it can which makes the video a bit jumpy but more current than IE11 (my preferred client).

Rather than explaining how the code works in this post, check out the GIST with comments (the client code isn't included, it is a standard HTML5 video tag with the node http server address). GIST is here: https://gist.github.com/deandob/9240090

I have not been able to find similar examples of this use case, so I hope the above explanation and code helps others, especially as I have learnt so much from this site and still consider myself a beginner!

Although this is the answer to my specific question, I have selected szatmary's answer as the accepted one as it is the most comprehensive.

I was getting this error:

The type com.ibm.portal.state.exceptions.StateException cannot be resolved. It is indirectly referenced from required .class files

Doing the following fixed it for me:

Properties -> Java build path -> Libraries -> Server Library[wps.base.v61]unbound -> Websphere Portal v6.1 on WAS 7 -> Finish -> OK

Here's an example using the stronger typing. Not sure if it's necessarily the best way though.

static void Main(string[] args)
{
    IList list = new List<int>() { 1, 3, 2, 5, 4, 6, 9, 8, 7 };
    List<int> stronglyTypedList = new List<int>(Cast<int>(list));
    stronglyTypedList.Sort();
}

private static IEnumerable<T> Cast<T>(IEnumerable list)
{
    foreach (T item in list)
    {
        yield return item;
    }
}

The Cast function is just a reimplementation of the extension method that comes with 3.5 written as a normal static method. It is quite ugly and verbose unfortunately.

Yes. Instead of passing in the instance attribute at class definition time, check it at runtime:

def check_authorization(f):
    def wrapper(*args):
        print args[0].url
        return f(*args)
    return wrapper

class Client(object):
    def __init__(self, url):
        self.url = url

    @check_authorization
    def get(self):
        print 'get'

>>> Client('http://www.google.com').get()
http://www.google.com
get

The decorator intercepts the method arguments; the first argument is the instance, so it reads the attribute off of that. You can pass in the attribute name as a string to the decorator and use getattr if you don't want to hardcode the attribute name:

def check_authorization(attribute):
    def _check_authorization(f):
        def wrapper(self, *args):
            print getattr(self, attribute)
            return f(self, *args)
        return wrapper
    return _check_authorization

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

As others have said, the style you're after is actually just the Mac OS checkbox style, so it will look radically different on other devices.

In fact both screenshots you linked show what checkboxes look like on Mac OS in Chrome, the grey one is shown at non-100% zoom levels.

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:
