ID % 2 is checking what the remainder is if you divide ID by 2. If you divide an even number by 2 it will always have a remainder of 0. Any other number (odd) will result in a non-zero value. Which is what is checking for.

Use the android.webkit.URLUtil on android:

URLUtil.isValidUrl(URL_STRING);

Note: It is just checking the initial scheme of URL, not that the entire URL is valid.

range creates a list, so if you do range(1, 10000000) it creates a list in memory with 9999999 elements.

xrange is a generator, so it is a sequence object is a that evaluates lazily.

This is true, but in Python 3, range() will be implemented by the Python 2 xrange(). If you need to actually generate the list, you will need to do:

list(range(1,100))

$(selectedDOM).find();

function looking for all dom objects inside the selected DOM. i.e.

<div id="mainDiv">
    <p>Paragraph 1</p>
    <p>Paragraph 2</p>
    <div id="innerDiv">
         <a href="#">link</a>
         <p>Paragraph 3</p>
    </div>
</div>

here if you write;

$("#mainDiv").find("p");

you will get tree p elements together. On the other side,

$("#mainDiv").children("p");

Function searching in the just children DOMs of the selected DOM object. So, by this code you will get just paragraph 1 and paragraph 2. It is so beneficial to prevent browser doing unnecessary progress.

You can always use the plot() function like so:

import matplotlib.pyplot as plt

import numpy as np

x = np.arange(10)
ys = [i+x+(i*x)**2 for i in range(10)]
plt.figure()
for y in ys:
    plt.plot(x, y, 'o')
plt.show()

Don't use Rstudio to update R. Rstudio IS NOT R, Rstudio is just an IDE. This answer is a summary of previous answers for different OS. For all OS it is convenient to have a look in advance what will happen with the packages you have already installed here.

WINDOWS ->> Open CMD/Powershell as an administrator and type "R" to go into interactive mode. If this does not work, search and run RGui.exe instead of writing R in the console ...and then:

lib_path <- gsub( "/", "\\\\" , Sys.getenv("R_LIBS_USER"))
install.packages("installr", lib = lib_path)
install.packages("stringr", lib_path)
library(stringr, lib.loc = lib_path)
library(installr, lib.loc = lib_path)
installr::updateR()

MacOS ->> You can use updateR package. The package is not on CRAN, so you’ll need to run the following code in Rgui:

install.packages("devtools")
devtools::install_github("AndreaCirilloAC/updateR")
updateR(admin_password = "PASSWORD") # Where "PASSWORD" stands for your system password

Note that it is planned to merge updateR and installR in the near future to work for both Mac and Windows.

Linux ->> For the moment installr is NOT available for Linux/MacOS (see documentation for current version 0.20). As R is installed, you can follow these instructions (in Ubuntu, although the idea is the same in other distros: add the source, update and upgrade and install.)

Here's a quick one: Removal of items is quicker.

You can scale bitmaps by using canvas.drawBitmap with providing matrix, for example:

public static Bitmap scaleBitmap(Bitmap bitmap, int wantedWidth, int wantedHeight) {
        Bitmap output = Bitmap.createBitmap(wantedWidth, wantedHeight, Config.ARGB_8888);
        Canvas canvas = new Canvas(output);
        Matrix m = new Matrix();
        m.setScale((float) wantedWidth / bitmap.getWidth(), (float) wantedHeight / bitmap.getHeight());
        canvas.drawBitmap(bitmap, m, new Paint());

        return output;
    }

One way to insert text inside a rectangle is to insert a foreign object, wich is a DIV, inside rect object.

This way, the text will respct the limits of the DIV.

var g = d3.select("svg");_x000D_
     _x000D_
g.append("rect")_x000D_
.attr("x", 0)_x000D_
.attr("y", 0)_x000D_
.attr("width","100%")_x000D_
.attr("height","100%")_x000D_
.attr("fill","#000");_x000D_
_x000D_
_x000D_
var fo = g.append("foreignObject")_x000D_
 .attr("width","100%");_x000D_
_x000D_
fo.append("xhtml:div")_x000D_
  .attr("style","width:80%;color:#FFF;margin-right: auto;margin-left: auto;margin-top:40px")_x000D_
  .text("Mussum Ipsum, cacilds vidis litro abertis Mussum Ipsum, cacilds vidis litro abertis Mussum Ipsum, cacilds vidis litro abertis");

I have hard time when trying to

• Create other db than admin
• Add new users and enable authentication to the db above

So I made 2020 answer here

My directory looks like this

+-- docker-compose.yml
+-- mongo-entrypoint
    +-- entrypoint.js

My docker-compose.yml looks like this

version: '3.4'
services:
  mongo-container:
    # If you need to connect to your db from outside this container 
    network_mode: host
    image: mongo:4.2
    environment:
        - MONGO_INITDB_ROOT_USERNAME=admin
        - MONGO_INITDB_ROOT_PASSWORD=pass
    ports:
      - "27017:27017"
    volumes:
      - "$PWD/mongo-entrypoint/:/docker-entrypoint-initdb.d/"
    command: mongod

Please change admin and pass with your need.

Inside mongo-entrypoint, I have entrypoint.js file with this content:

var db = connect("mongodb://admin:pass@localhost:27017/admin");

db = db.getSiblingDB('new_db'); // we can not use "use" statement here to switch db

db.createUser(
    {
        user: "user",
        pwd: "pass",
        roles: [ { role: "readWrite", db: "new_db"} ],
        passwordDigestor: "server",
    }
)

Here again you need to change admin:pass to your root mongo credentials in your docker-compose.yml that you stated before. In additional you need to change new_db, user, pass to your new database name and credentials that you need.

Now you can:

docker-compose up -d

And connect to this db from localhost, please note that I already have mongo cli, you can install it or you can exec to the container above to use mongo command:

mongo new_db -u user -p pass

Or you can connect from other computer

mongo host:27017/new_db -u user -p pass

When searching for an answer to the very same question I came across gem_unused.
You also might wanna read this article: http://chill.manilla.com/2012/12/31/clean-up-your-dirty-gemsets/
The source code is available on GitHub: https://github.com/apolzon/gem_unused

You should go the submodule dir and run git status.

You may see a lot of files were deleted. You may run

1. git reset .

2. git checkout .

3. git fetch -p

4. git rm --cached submodules //submoudles is your name

5. git submoudle add ....

Here's an answer, based on (and I think an improvement on) Tester101's answer, expressed as a subroutine, with the CopyFile line once instead of three times, and prepared to handle changing the file name as the copy is made (no hard-coded destination directory). I also found I had to delete the target file before copying to get this to work, but that might be a Windows 7 thing. The WScript.Echo statements are because I didn't have a debugger and can of course be removed if desired.

Sub CopyFile(SourceFile, DestinationFile)

    Set fso = CreateObject("Scripting.FileSystemObject")

    'Check to see if the file already exists in the destination folder
    Dim wasReadOnly
    wasReadOnly = False
    If fso.FileExists(DestinationFile) Then
        'Check to see if the file is read-only
        If fso.GetFile(DestinationFile).Attributes And 1 Then 
            'The file exists and is read-only.
            WScript.Echo "Removing the read-only attribute"
            'Remove the read-only attribute
            fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes - 1
            wasReadOnly = True
        End If

        WScript.Echo "Deleting the file"
        fso.DeleteFile DestinationFile, True
    End If

    'Copy the file
    WScript.Echo "Copying " & SourceFile & " to " & DestinationFile
    fso.CopyFile SourceFile, DestinationFile, True

    If wasReadOnly Then
        'Reapply the read-only attribute
        fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes + 1
    End If

    Set fso = Nothing

End Sub

You can use the library libphonenumber from Google.

PhoneNumberUtil phoneNumberUtil = PhoneNumberUtil.getInstance();
String decodedNumber = null;
PhoneNumber number;
    try {
        number = phoneNumberUtil.parse(encodedHeader, null);
        decodedNumber = phoneNumberUtil.format(number, PhoneNumberFormat.E164);
    } catch (NumberParseException e) {
        e.printStackTrace();
    }

BalusC answer didn't work for me (bash console on Ubuntu). Some stuff remained at the end of the line. So I rolled over again with spaces. Thread.sleep() is used in the below snippet so you can see what's happening.

String foo = "the quick brown fox jumped over the fence";
System.out.printf(foo);
try {Thread.sleep(1000);} catch (InterruptedException e) {}
System.out.printf("%s", mul("\b", foo.length()));
try {Thread.sleep(1000);} catch (InterruptedException e) {}
System.out.printf("%s", mul(" ", foo.length()));
try {Thread.sleep(1000);} catch (InterruptedException e) {}
System.out.printf("%s", mul("\b", foo.length()));

where mul is a simple method defined as:

private static String mul(String s, int n) {
    StringBuilder builder = new StringBuilder();
    for (int i = 0; i < n ; i++)
        builder.append(s);
    return builder.toString();
}

(Guava's Strings class also provides a similar repeat method)

I'm using Firefox, and my working solution is very close to obysky. The only difference is that the method you call in an svg element will return multiple rects and you need to select the first one.

var chart = document.getElementsByClassName("chart")[0];
var width = chart.getClientRects()[0].width;
var height = chart.getClientRects()[0].height;

It's the resources required to set up an operation. It might seem unrelated, but necessary.

It's like when you need to go somewhere, you might need a car. But, it would be a lot of overhead to get a car to drive down the street, so you might want to walk. However, the overhead would be worth it if you were going across the country.

In computer science, sometimes we use cars to go down the street because we don't have a better way, or it's not worth our time to "learn how to walk".

@RequestParam annotation used for accessing the query parameter values from the request. Look at the following request URL:

http://localhost:8080/springmvc/hello/101?param1=10&param2=20

In the above URL request, the values for param1 and param2 can be accessed as below:

public String getDetails(
    @RequestParam(value="param1", required=true) String param1,
        @RequestParam(value="param2", required=false) String param2){
...
}

The following are the list of parameters supported by the @RequestParam annotation:

• defaultValue – This is the default value as a fallback mechanism if request is not having the value or it is empty.
• name – Name of the parameter to bind
• required – Whether the parameter is mandatory or not. If it is true, failing to send that parameter will fail.
• value – This is an alias for the name attribute

@PathVariable

@PathVariable identifies the pattern that is used in the URI for the incoming request. Let’s look at the below request URL:

http://localhost:8080/springmvc/hello/101?param1=10&param2=20

The above URL request can be written in your Spring MVC as below:

@RequestMapping("/hello/{id}")    public String getDetails(@PathVariable(value="id") String id,
    @RequestParam(value="param1", required=true) String param1,
    @RequestParam(value="param2", required=false) String param2){
.......
}

The @PathVariable annotation has only one attribute value for binding the request URI template. It is allowed to use the multiple @PathVariable annotation in the single method. But, ensure that no more than one method has the same pattern.

Also there is one more interesting annotation: @MatrixVariable

http://localhost:8080/spring_3_2/matrixvars/stocks;BT.A=276.70,+10.40,+3.91;AZN=236.00,+103.00,+3.29;SBRY=375.50,+7.60,+2.07

And the Controller method for it

 @RequestMapping(value = "/{stocks}", method = RequestMethod.GET)
  public String showPortfolioValues(@MatrixVariable Map<String, List<String>> matrixVars, Model model) {

    logger.info("Storing {} Values which are: {}", new Object[] { matrixVars.size(), matrixVars });

    List<List<String>> outlist = map2List(matrixVars);
    model.addAttribute("stocks", outlist);

    return "stocks";
  }

But you must enable:

<mvc:annotation-driven enableMatrixVariables="true" >

angular.module('app').directive('conversation', function() {
    return {
        restrict: 'E',
        link: function ($scope, $elm, $attr) {
            $scope.$watch("some_prop", function (newValue, oldValue) {
                  var typeId = $attr.type-id;
                  // Your logic.
            });
        }
    };
}

You may also be interested in Swift 4.2 / XCode 10 compiler directives like

#warning("Some string to display")

and

#error("Some error to display")

It might be useful when you really don't want to miss something.

Here's how to look in the documentation.

First, you're dealing with IO, so look in the java.io package.

There are two classes that look interesting: FileFilter and FileNameFilter. When I clicked on the first, it showed me that there was a a listFiles() method in the File class. And the documentation for that method says:

Returns an array of abstract pathnames denoting the files in the directory denoted by this abstract pathname.

Scrolling up in the File JavaDoc, I see the constructors. And that's really all I need to be able to create a File instance and call listFiles() on it. Scrolling still further, I can see some information about how files are named in different operating systems.

This is actually the conventional use of the break statement. If the break statement wasn't nested in an if block the for loop could only ever execute one time.

MSDN lists this as their example for the break statement.

In combination with lists, dicts and sets, there are also another interesting python objects, OrderedDicts.

Ordered dictionaries are just like regular dictionaries but they remember the order that items were inserted. When iterating over an ordered dictionary, the items are returned in the order their keys were first added.

OrderedDicts could be useful when you need to preserve the order of the keys, for example working with documents: It's common to need the vector representation of all terms in a document. So using OrderedDicts you can efficiently verify if a term has been read before, add terms, extract terms, and after all the manipulations you can extract the ordered vector representation of them.

Think of it as your stylesheet(s) referring to ("selecting") elements in your HTML page, not the other way around.

This will bring back totals per property and type

SELECT  PropertyID,
        TYPE,
        SUM(Amount)
FROM    yourTable
GROUP BY    PropertyID,
            TYPE

This will bring back only active values

SELECT  PropertyID,
        TYPE,
        SUM(Amount)
FROM    yourTable
WHERE   EndDate IS NULL
GROUP BY    PropertyID,
            TYPE

and this will bring back totals for properties

SELECT  PropertyID,
        SUM(Amount)
FROM    yourTable
WHERE   EndDate IS NULL
GROUP BY    PropertyID

Set the architecture in build setting to Standard architectures(armv7,armv7s)

iPhone 5S is powered by A7 64bit processor. From apple docs

Xcode can build your app with both 32-bit and 64-bit binaries included. This combined binary requires a minimum deployment target of iOS 7 or later.

Note: A future version of Xcode will let you create a single app that supports the 32-bit runtime on iOS 6 and later, and that supports the 64-bit runtime on iOS 7.

From the documentation what i understood is

• Xcode can create both 64bit 32bit binaries for a single app but the deployment target should be iOS7. They are saying in future it will be iOS 6.0
• 32 bit binary will work fine in iPhone 5S(64 bit processor).

Update (Xcode 5.0.1)
In Xcode 5.0.1 they added the support to create 64 bit binary for iOS 5.1.1 onwards.

Xcode 5.0.1 can build your app with both 32-bit and 64-bit binaries included. This combined binary requires a minimum deployment target of iOS 5.1.1 or later. The 64-bit binary runs only on 64-bit devices running iOS 7.0.3 and later.

Update (Xcode 5.1)
Xcode 5.1 made significant change in the architecture section. This answer will be a followup for you. Check this

You seem to be specifying the form to use a HTTP 'GET' request using FormMethod.Get. This will not work unless you tell it to do a post as that is what you seem to want the ActionResult to do. This will probably work by changing FormMethod.Get to FormMethod.Post.

As well as this you may also want to think about how Get and Post requests work and how these interact with the Model.

To spool from a BEGIN END block is pretty simple. For example if you need to spool result from two tables into a file, then just use the for loop. Sample code is given below.

BEGIN

FOR x IN 
(
    SELECT COLUMN1,COLUMN2 FROM TABLE1
    UNION ALL
    SELECT COLUMN1,COLUMN2 FROM TABLEB
)    
LOOP
    dbms_output.put_line(x.COLUMN1 || '|' || x.COLUMN2);
END LOOP;

END;
/

This seemed easier to think about where either of two parameters could be passed into a stored procedure. It seems to work:

SELECT * 
FROM x 
WHERE CONDITION1
AND ((@pol IS NOT NULL AND x.PolicyNo = @pol) OR (@st IS NOT NULL AND x.State = @st))
AND OTHERCONDITIONS

try to use heading, no need extra css

If it is not defined in the web service or application or server (apache or IIS) that is hosting the web service consumable then you could create infinite connections until failure

I tried all of the above, in a nutshell all you need is

let sorted = dictionary.sorted { $0.key < $1.key }
let keysArraySorted = Array(sorted.map({ $0.key }))
let valuesArraySorted = Array(sorted.map({ $0.value }))

Simply call list on the generator.

lst = list(gen)
lst

Be aware that this affects the generator which will not return any further items.

You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.

Tested on this file:

def gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
import ipdb
ipdb.set_trace()

g1 = gen()

text = "aha" + "bebe"

mylst = range(10, 20)

which when run:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.

General method for escaping function/variable/debugger name conflicts

There are debugger commands p and pp that will print and prettyprint any expression following them.

So you could use it as follows:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c

There is also an exec command, called by prefixing your expression with !, which forces debugger to take your expression as Python one.

ipdb> !list(g1)
[]

For more details see help p, help pp and help exec when in debugger.

ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

Fun 'base_url' snippet!

if (!function_exists('base_url')) {
    function base_url($atRoot=FALSE, $atCore=FALSE, $parse=FALSE){
        if (isset($_SERVER['HTTP_HOST'])) {
            $http = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off' ? 'https' : 'http';
            $hostname = $_SERVER['HTTP_HOST'];
            $dir =  str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);

            $core = preg_split('@/@', str_replace($_SERVER['DOCUMENT_ROOT'], '', realpath(dirname(__FILE__))), NULL, PREG_SPLIT_NO_EMPTY);
            $core = $core[0];

            $tmplt = $atRoot ? ($atCore ? "%s://%s/%s/" : "%s://%s/") : ($atCore ? "%s://%s/%s/" : "%s://%s%s");
            $end = $atRoot ? ($atCore ? $core : $hostname) : ($atCore ? $core : $dir);
            $base_url = sprintf( $tmplt, $http, $hostname, $end );
        }
        else $base_url = 'http://localhost/';

        if ($parse) {
            $base_url = parse_url($base_url);
            if (isset($base_url['path'])) if ($base_url['path'] == '/') $base_url['path'] = '';
        }

        return $base_url;
    }
}

Use as simple as:

//  url like: http://stackoverflow.com/questions/2820723/how-to-get-base-url-with-php

echo base_url();    //  will produce something like: http://stackoverflow.com/questions/2820723/
echo base_url(TRUE);    //  will produce something like: http://stackoverflow.com/
echo base_url(TRUE, TRUE); || echo base_url(NULL, TRUE);    //  will produce something like: http://stackoverflow.com/questions/
//  and finally
echo base_url(NULL, NULL, TRUE);
//  will produce something like: 
//      array(3) {
//          ["scheme"]=>
//          string(4) "http"
//          ["host"]=>
//          string(12) "stackoverflow.com"
//          ["path"]=>
//          string(35) "/questions/2820723/"
//      }

I was able to do this:

String a;
if(rs.getString("column") != null)
{
    a = "Hello world!";
}
else
{
    a = "Bye world!";
}

Under the covers there will be some form of URL loading request. You can't load images or any other content via this method from a local file system.

Your image needs to be loaded via a web server, so accessed via a proper http URL.

Create view Schema1.viewName1 as (select * from plaplapla)

Schema1 has all the tables

Create view Schema2.viewName2 as (select * from schema1.viewName1)

schema2 has no tables(only views schema)

In this case you can execute (select * from viewName2) in schema2 , BUT .. If you deleted viewNmae1 from Schema1 , Then ViewName2 will not work..

sprintf(Buffer,"Hello World");
sprintf(&Buffer[strlen[Buffer]],"Good Morning");
sprintf(&Buffer[strlen[Buffer]],"Good Afternoon");

        var twitterObject = JToken.Parse(jsonString);
        var trendsArray = twitterObject.Children<JProperty>().FirstOrDefault(x => x.Name == "trends").Value;


        foreach (var item in trendsArray.Children())
        {
            var itemProperties = item.Children<JProperty>();
            //you could do a foreach or a linq here depending on what you need to do exactly with the value
            var myElement = itemProperties.FirstOrDefault(x => x.Name == "url");
            var myElementValue = myElement.Value; ////This is a JValue type
        }
    }

So call Children on your JArray to get each JObject in JArray. Call Children on each JObject to access the objects properties.

foreach(var item in yourJArray.Children())
{
    var itemProperties = item.Children<JProperty>();
    //you could do a foreach or a linq here depending on what you need to do exactly with the value
    var myElement = itemProperties.FirstOrDefault(x => x.Name == "url");
    var myElementValue = myElement.Value; ////This is a JValue type
}

You might be better off editing a file inside of cygwin shell. Normally it has default user directory when you start it up. You can edit a file from the shell doing something like "vi somefile.c" or "emacs somefile.c". That's assuming vi or emacs are installed in cygwin.

If you want to file on your desktop, you'll have to go to a path similar (on XP) to "/cygwindrive/c/Documents\ and\ Settings/Frank/Desktop" (If memory serves correctly). Just cd to that path, and run your command on the file.

This is a question with a simple answer and a long-winded answer.

The simple answer is the heap. Classes and all of the data applying to classes (not instance data) is stored in the Permanent Generation section of the heap.

The long answer is already on stack overflow:

There is a thorough description of memory and garbage collection in the JVM as well as an answer that talks more concisely about it.

An alternative approach would be to "emulate" bold text via text-shadow. This has the bonus (/malus, depending on your case) to work also on font icons.

   nav li a:hover {
      text-decoration: none;
      text-shadow: 0 0 1px; /* "bold" */
   }

Kinda hacky, although it saves you from duplicating text (which is useful if it is a lot, as it was in my case).

document.getElementsByName("name") will get several elements called by same name . document.getElementsByName("name")[Number] will get one of them. document.getElementsByName("name")[Number].value will get the value of paticular element.

The key of this question is this:
The name of elements is not unique, it is usually used for several input elements in the form.
On the other hand, the id of the element is unique, which is the only definition for a particular element in a html file.

Try this Zoom Control: http://wpfextensions.codeplex.com

usage of the control is very simple, reference to the wpfextensions assembly than:

<wpfext:ZoomControl>
    <Image Source="..."/>
</wpfext:ZoomControl>

Scrollbars not supported at this moment. (It will be in the next release which will be available in one or two week).

I recently came across Python 3 interpreter at CompileOnline.

As per Link: http://bavotasan.com/2011/style-select-box-using-only-css/ there are lot of extra rework that needs to be done(Put extra div and position the image there. Also the design will break as the option drilldown will be mis alligned to the the select.

Here is an easy and simple way which will allow you to put your own dropdown image and remove the browser default dropdown.(Without using any extra div). Its cross browser as well.

HTML

<select class="dropdown" name="drop-down">
  <option value="select-option">Please select...</option>
  <option value="Local-Community-Enquiry">Option 1</option>
  <option value="Bag-Packing-in-Store">Option 2</option>
</select>

CSS

select.dropdown {
  margin: 0px;
  margin-top: 12px;
  height: 48px;
  width: 100%;
  border-width: 1px;
  border-style: solid;
  border-color: #666666;
  padding: 9px;
  font-family: tescoregular;
  font-size: 16px;
  color: #666666;
  -webkit-appearance: none;
  -webkit-border-radius: 0px;
  -moz-appearance: none;
  appearance: none;
  background: url('yoururl/dropdown.png') no-repeat 97% 50% #ffffff;
  background-size: 11px 7px;
}

How do I print out my $ids and $nIds?

print "$ids\n";
print "$nIds\n";

I tried simply print $ids, but Perl complains.

Complains about what? Uninitialised value? Perhaps your loop was never entered due to an error opening the file. Be sure to check if open returned an error, and make sure you are using use strict; use warnings;.

my ($ids, $nIds) is a list, right? With two elements?

It's a (very special) function call. $ids,$nIds is a list with two elements.

I had the same issue. I came up with a simple solution. Use fragment .replace instead of fragment .add. Replacing fragment doing the same thing as adding fragment and then removing it manually.

getFragmentManager().beginTransaction().replace(fragment).commit();

instead of

getFragmentManager().beginTransaction().add(fragment).commit();

I had the same problem. I solve it with a for loop.

Example:

If I want to write in 2 identical tables, using a loop

for x = 0 to 1

 if x = 0 then TableToWrite = "Table1"
 if x = 1 then TableToWrite = "Table2"
  Sql = "INSERT INTO " & TableToWrite & " VALUES ('1','2','3')"
NEXT

either

ArrTable = ("Table1", "Table2")

for xArrTable = 0 to Ubound(ArrTable)
 Sql = "INSERT INTO " & ArrTable(xArrTable) & " VALUES ('1','2','3')"
NEXT

If you have a small query I don't know if this is the best solution, but if you your query is very big and it is inside a dynamical script with if/else/case conditions this is a good solution.

As Simon Hürlimann already explained, Open3 is safer than backticks etc.

require 'open3'
output = Open3.popen3("ls") { |stdin, stdout, stderr, wait_thr| stdout.read }

Note that the block form will auto-close stdin, stdout and stderr- otherwise they'd have to be closed explicitly.

PhpStorm supports all the features of WebStorm but some are not bundled so you might need to install the corresponding plugin for some framework via Settings > Plugins > Install JetBrains Plugin.

Expanding on @Shripad's and @Ivan's answer, I would recommend that you use Node.js's standard module.export functionality.

In your file for constants (e.g. constants.js), you'd write constants like this:

const CONST1 = 1;
module.exports.CONST1 = CONST1;

const CONST2 = 2;
module.exports.CONST2 = CONST2;

Then in the file in which you want to use those constants, write the following code:

const {CONST1 , CONST2} = require('./constants.js');

If you've never seen the const { ... } syntax before: that's destructuring assignment.

quoting ivan n : "If importing a database, you need to create one first with the same name, then select it and then IMPORT the existing database to it. Hope it works for you!"

These are the steps: Create a Database, for instance my_db1, utf8_general_ci. Then click to go inside this database. Then click "import", and select the database: my_db1.sql

That should be all.

I had the same issue twice, but in the second time I realized it wasn't a problem on Tomcat at all.. Try to delete the cache of your browser, refresh the page and see if the new version of the page on your server is being shown up. It worked with me.

Use window.intro inside of $(document).ready().

Any .apk file from market or unsigned

1. If you apk is downloaded from market and hence signed Install Astro File Manager from market. Open Astro > Tools > Application Manager/Backup and select the application to backup on to the SD card . Mount phone as USB drive and access 'backupsapps' folder to find the apk of target app (lets call it app.apk) . Copy it to your local drive same is the case of unsigned .apk.

2. Download Dex2Jar zip from this link: SourceForge

3. Unzip the downloaded zip file.

4. Open command prompt & write the following command on reaching to directory where dex2jar exe is there and also copy the apk in same directory.

   dex2jar targetapp.apk file(./dex2jar app.apk on terminal)

5. http://jd.benow.ca/ download decompiler from this link.

6. Open ‘targetapp.apk.dex2jar.jar’ with jd-gui File > Save All Sources to sava the class files in jar to java files.

For beginners, I wanted to add to the accepted answer, because a couple of subtleties were unclear to me:

To find and modify text (not completely replace),

1. In the "Find" step, you can use regex with "capturing groups," e.g. your search could be la la la (group1) blah blah (group2), using parentheses.

2. And then in the "Replace" step, you can refer to the capturing groups via $1, $2 etc.

So, for example, in this case we could find the relevant text with just <h1>.+?<\/h1> (no parentheses), but putting in the parentheses <h1>(.+?)<\/h1> allows us to refer to the sub-match in between them as $1 in the replace step. Cool!

Notes

• To turn on Regex in the Find Widget, click the .* icon, or press Cmd/Ctrl Alt R

• $0 refers to the whole match

• Finally, the original question states that the replace should happen "within a document," so you can use the "Find Widget" (Cmd or Ctrl + F), which is local to the open document, instead of "Search", which opens a bigger UI and looks across all files in the project.

The problem is in the font-weight.
For Font Awesome 5 you have to use {font-weight:900}

LinearLayout - In LinearLayout, views are organized either in vertical or horizontal orientation.

RelativeLayout - RelativeLayout is way more complex than LinearLayout, hence provides much more functionalities. Views are placed, as the name suggests, relative to each other.

FrameLayout - It behaves as a single object and its child views are overlapped over each other. FrameLayout takes the size of as per the biggest child element.

Coordinator Layout - This is the most powerful ViewGroup introduced in Android support library. It behaves as FrameLayout and has a lot of functionalities to coordinate amongst its child views, for example, floating button and snackbar, Toolbar with scrollable view.

SQLite database FAQ: How do I drop a SQLite database?

People used to working with other databases are used to having a "drop database" command, but in SQLite there is no similar command. The reason? In SQLite there is no "database server" -- SQLite is an embedded database, and your database is entirely contained in one file. So there is no need for a SQLite drop database command.

To "drop" a SQLite database, all you have to do is delete the SQLite database file you were accessing.

Jquery Datepicker defaultDate ONLY set the default date that you chose on the calendar that pops up when you click on your field. If you want the default date to APPEAR on your input before the user clicks on the field you should give a val() to your field. Something like this:

$("#searchDateFrom").datepicker({ defaultDate: "-1y -1m -6d" });
$("#searchDateFrom").val((date.getMonth()) + '/' + (date.getDate() - 6) + '/' + (date.getFullYear() - 1));

You're nearly there!

For a bold text, you should have this: <b> bold text</b> or <strong>bold text</strong> They have the same result.

Working example - JSfiddle

Nick Vogt at H3XED posted this syntax: https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080

Take this link and replace the expression "VIDEOID" with the (shortened/shared) ID of the video.

Exapmple for ID: i3jNECZ3ybk looks like this: ... /v/i3jNECZ3ybk?version=3&vq=hd1080

What you get as a result is the standalone 1080p video but not in the Tube environment.

Scripts are loaded in the order you have defined them in the HTML.

Therefore if you first load:

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

without loading jQuery first, then $ is not defined.

You need to first load jQuery so that you can use it.

I would also recommend placing your scripts at the bottom of your HTML for performance reasons.

NR starts at 1, so use

awk '{print NR-1 "," $0}'

In case you want to check if a program exists and is really a program, not a Bash built-in command, then command, type and hash are not appropriate for testing as they all return 0 exit status for built-in commands.

For example, there is the time program which offers more features than the time built-in command. To check if the program exists, I would suggest using which as in the following example:

# First check if the time program exists
timeProg=`which time`
if [ "$timeProg" = "" ]
then
  echo "The time program does not exist on this system."
  exit 1
fi

# Invoke the time program
$timeProg --quiet -o result.txt -f "%S %U + p" du -sk ~
echo "Total CPU time: `dc -f result.txt` seconds"
rm result.txt

If you want to delete manually (for me it was easier), follow this:

Let's get this example with "teste".

1 - First change the explorer to "project" and open "settings.gradle";

2 - Delete the module you want;

3 - Go to your root folder of your project and delete the module folder.

Sorting by date doesn't require anything special. Just sort by the desired date field of the collection.

Updated for the 1.4.28 node.js native driver, you can sort ascending on datefield using any of the following ways:

collection.find().sort({datefield: 1}).toArray(function(err, docs) {...});
collection.find().sort('datefield', 1).toArray(function(err, docs) {...});
collection.find().sort([['datefield', 1]]).toArray(function(err, docs) {...});
collection.find({}, {sort: {datefield: 1}}).toArray(function(err, docs) {...});
collection.find({}, {sort: [['datefield', 1]]}).toArray(function(err, docs) {...});

'asc' or 'ascending' can also be used in place of the 1.

To sort descending, use 'desc', 'descending', or -1 in place of the 1.

If the number of elements in the array is not given, you can alternatively make use of list comprehension like:

str_arr = raw_input().split(' ') //will take in a string of numbers separated by a space
arr = [int(num) for num in str_arr]

Try this,

        var arg = new { i = 123, j = 456 };
        var task = new TaskFactory().StartNew(new Func<dynamic, int>((argument) =>
        {
            dynamic x = argument.i * argument.j;
            return x;
        }), arg, CancellationToken.None, TaskCreationOptions.AttachedToParent, TaskScheduler.Default);
        task.Wait();
        var result = task.Result;

You can also check whether div has specific children or not,

if($('#myDiv').has('select').length>0)
{
   // Do something here.
   console.log("you can log here");

}

If you are only handling scrolling to an input element, you can use focus(). For example, if you wanted to scroll to the first visible input:

$(':input:visible').first().focus();

Or the first visible input in an container with class .error:

$('.error :input:visible').first().focus();

Thanks to Tricia Ball for pointing this out!

As @gaurang171 mentioned, we can use .closest() which will return the first ancestor, or the closest to our delete button, and use .remove() to remove it.

This is how we can implement it using jQuery click event instead of using JavaScript onclick.

@Ahamed has a point, but if you're insisting on using lists so you can have three arraylist like this:

ArrayList<Integer> first = new ArrayList<Integer>(Arrays.AsList(100,100,100,100,100));
ArrayList<Integer> second = new ArrayList<Integer>(Arrays.AsList(50,35,25,45,65));
ArrayList<Integer> third = new ArrayList<Integer>();

for(int i = 0; i < first.size(); i++) {
      third.add(first.get(i));
      third.add(second.get(i));
}

Edit: If you have those values on your list that below:

List<double[]> values = new ArrayList<double[]>(2);

what you want to do is combine them, right? You can try something like this: (I assume that both array are same sized, otherwise you need to use two for statement)

ArrayList<Double> yourArray = new ArrayList<Double>();
for(int i = 0; i < values.get(0).length; i++) {
    yourArray.add(values.get(0)[i]);
    yourArray.add(values.get(1)[i]);
}

Bar is guaranteed not to change the object it is being invoked on. See the section about const correctness in the C++ FAQ, for example.

The necessary method is Mockito#verify:

public static <T> T verify(T mock,
                           VerificationMode mode)

mock is your mocked object and mode is the VerificationMode that describes how the mock should be verified. Possible modes are:

verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");

You'll need these static imports from the Mockito class in order to use the verify method and these verification modes:

import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;

So in your case the correct syntax will be:

Mockito.verify(mock, times(4)).send()

This verifies that the method send was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.

If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode. A simple

verify(mock).someMethod("was called once");

would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");.

It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");, but we can write

verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");

instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.

Note:

• please look forward to get results.
• that this program often bug.

Then

#include <iostream>
#include <ctime>

#ifdef _WIN32
#include <windows.h>
#define sleep(x) Sleep(x*1000)
#endif

int main() {
  time_t c = time(NULL);
retry:
  sleep(1);
  std::cout << time(NULL)-c << std::endl;
goto retry;
}

I would go with such code:

var oBox = $("#blackbox");
var curClass = oBox.attr("class");
var newClass = (curClass == "bg_black") ? "bg_pink" : "bg_black";
oBox.removeClass().addClass(newClass);

To have it working, you first have to change your CSS and remove the background from the #blackbox declaration, add those two classes:

.bg_black { background-color: #000; }
.bg_pink { background-color: pink; }

And assign the class bg_black to the blackbox element initially.

for 1D and 2D arrays you can use np.savetxt to print using a specific format string:

>>> import sys
>>> x = numpy.arange(20).reshape((4,5))
>>> numpy.savetxt(sys.stdout, x, '%5.2f')
 0.00  1.00  2.00  3.00  4.00
 5.00  6.00  7.00  8.00  9.00
10.00 11.00 12.00 13.00 14.00
15.00 16.00 17.00 18.00 19.00

Your options with numpy.set_printoptions or numpy.array2string in v1.3 are pretty clunky and limited (for example no way to suppress scientific notation for large numbers). It looks like this will change with future versions, with numpy.set_printoptions(formatter=..) and numpy.array2string(style=..).

You want to use single quotes:

if(c=='\0')

Double quotes (") are for strings, which are sequences of characters. Single quotes (') are for individual characters.

However, the end-of-line is represented by the newline character, which is '\n'.

Note that in both cases, the backslash is not part of the character, but just a way you represent special characters. Using backslashes you can represent various unprintable characters and also characters which would otherwise confuse the compiler.

Actually, I did not want to be dependent of anything else but Python (Cairo, Ink.., etc.) My requirements were to be as simple as possible, at most, a simple pip install "savior" would suffice, that's why any of those above didn't suit for me.

A bundled stylesheet may save page load performance but the more styles there are the slower the browser renders animations on the page you are on. This is caused by the huge amount of unused styles that may not be on the page you are on but the browser still has to calculate.

See: https://benfrain.com/css-performance-revisited-selectors-bloat-expensive-styles/

Bundled stylesheets advantages: - page load performance

Bundled stylesheets disadvantages: - slower behaviour, which can cause choppyness during scrolling, interactivity, animation,

Conclusion: To solve both problems, for production the ideal solution is to bundle all the css into one file to save on http requests, but use javascript to extract from that file, the css for the page you are on and update the head with it.

To know which shared components are needed per page, and to reduce complexity, it would be nice to have declared all the components this particular page uses - for example:

<style href="global.css" rel="stylesheet"/>
<body data-shared-css-components="x,y,z">

jQuery 1.4.1 now supports "hover" for live() events, but only with one event handler function:

$("table tr").live("hover",

function () {

});

Alternatively, you can provide two functions, one for mouseenter and one for mouseleave:

$("table tr").live({
    mouseenter: function () {

    },
    mouseleave: function () {

    }
});

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

In more modern browsers (including IE 10+) you can now use calc():

.moveto {
  top: 0px;
  left: calc(100% - 50px);
}

If you want to ignore a property, mark it as optional by adding a question mark:

interface IPerson {
    firstName: string;
    lastName?: string;
}

Well, the problem you have is wrong line ending/encoding for notepad. Notepad uses Windows' line endings - \r\n and you use \n.

Why is printf("%8d\n", intval); not working for you? It should...

You did not show the format strings for any of your "not working" examples, so I'm not sure what else to tell you.

#include <stdio.h>

int
main(void)
{
        int i;
        for (i = 1; i <= 10000; i*=10) {
                printf("[%8d]\n", i);
        }
        return (0);
}

$ ./printftest
[       1]
[      10]
[     100]
[    1000]
[   10000]

EDIT: response to clarification of question:

#include <math.h>
int maxval = 1000;
int width = round(1+log(maxval)/log(10));
...
printf("%*d\n", width, intval);

The width calculation computes log base 10 + 1, which gives the number of digits. The fancy * allows you to use the variable for a value in the format string.

You still have to know the maximum for any given run, but there's no way around that in any language or pencil & paper.

I had the same problem I used the solution offered above - I dropped the SYNONYM, created a VIEW with the same name as the synonym. it had a select using the dblink , and gave GRANT SELECT to the other schema It worked great.

In my opinion this is a design flaw of pytz library. It should be more reliable to specify a timezone using the offset, e.g.

pytz.construct("UTC-07:00")

which gives you Canada/Pacific timezone.

You can achieve this with the following code:

$("input").change(function(e) {

    for (var i = 0; i < e.originalEvent.srcElement.files.length; i++) {

        var file = e.originalEvent.srcElement.files[i];

        var img = document.createElement("img");
        var reader = new FileReader();
        reader.onloadend = function() {
             img.src = reader.result;
        }
        reader.readAsDataURL(file);
        $("input").after(img);
    }
});

Demo: http://jsfiddle.net/ugPDx/

string root = @"C:\Temp";

string subdir = @"C:\Temp\Mahesh";

// If directory does not exist, create it.

if (!Directory.Exists(root))
{

Directory.CreateDirectory(root);

}

The CreateDirectory is also used to create a sub directory. All you have to do is to specify the path of the directory in which this subdirectory will be created in. The following code snippet creates a Mahesh subdirectory in C:\Temp directory.

// Create sub directory

if (!Directory.Exists(subdir))
{

Directory.CreateDirectory(subdir);

}

Please never do this in real projects:

document.getElementById("span").innerHTML = "String".fontsize(25);

<span id="span"></span>

If obj Is Nothing Then
    ' need to initialize obj: '
    Set obj = ...
Else
    ' obj already set / initialized. '
End If

Or, if you prefer it the other way around:

If Not obj Is Nothing Then
    ' obj already set / initialized. '
Else
    ' need to initialize obj: '
    Set obj = ...
End If

With Java 11 you won't have to go through this rigmarole anymore!

Instead, you can do this:

> java MyApp.java

You don't have to compile beforehand, as it's all done in one step.

You can get the Java 11 JDK here: JDK 11 GA Release

1. Use a version.py file only with __version__ = <VERSION> param in the file. In the setup.py file import the __version__ param and put it's value in the setup.py file like this: version=__version__
2. Another way is to use just a setup.py file with version=<CURRENT_VERSION> - the CURRENT_VERSION is hardcoded.

Since we don't want to manually change the version in the file every time we create a new tag (ready to release a new package version), we can use the following..

I highly recommend bumpversion package. I've been using it for years to bump a version.

start by adding version=<VERSION> to your setup.py file if you don't have it already.

You should use a short script like this every time you bump a version:

bumpversion (patch|minor|major) - choose only one option
git push
git push --tags

Then add one file per repo called: .bumpversion.cfg:

[bumpversion]
current_version = <CURRENT_TAG>
commit = True
tag = True
tag_name = {new_version}
[bumpversion:file:<RELATIVE_PATH_TO_SETUP_FILE>]

Note:

• You can use __version__ parameter under version.py file like it was suggested in other posts and update the bumpversion file like this: [bumpversion:file:<RELATIVE_PATH_TO_VERSION_FILE>]
• You must git commit or git reset everything in your repo, otherwise you'll get a dirty repo error.
• Make sure that your virtual environment includes the package of bumpversion, without it it will not work.

When use codeIgniter Framework then refer this active records link. how the data interact with structure and more.

The following functions allow you to build SQL SELECT statements.

Selecting Data

$this->db->get();

Runs the selection query and returns the result. Can be used by itself to retrieve all records from a table:

$query = $this->db->get('mytable');

With access to each row

$query = $this->db->get('mytable');

foreach ($query->result() as $row)
{
    echo $row->title;
}

Where clues

$this->db->get_where();

EG:

 $query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);

Select field

$this->db->select('title, content, date');

$query = $this->db->get('mytable');

// Produces: SELECT title, content, date FROM mytable

E.G

$this->db->select('(SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid', FALSE); 
$query = $this->db->get('mytable');

You say "I am not using a forms to manipulate the data." But you are doing a POST. Therefore, you are, in fact, using a form, even if it's empty.

$.ajax's dataType tells jQuery what type the server will return, not what you are passing. POST can only pass a form. jQuery will convert data to key/value pairs and pass it as a query string. From the docs:

Data to be sent to the server. It is converted to a query string, if not already a string. It's appended to the url for GET-requests. See processData option to prevent this automatic processing. Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key i.e. {foo:["bar1", "bar2"]} becomes '&foo=bar1&foo=bar2'.

Therefore:

1. You aren't passing JSON to the server. You're passing JSON to jQuery.
2. Model binding happens in the same way it happens in any other case.

The methods in the Path class are syntactic, meaning that they operate on the Path instance. But eventually you must access the file system to verify that a particular Path exists

 File file = new File("FileName");
 if(file.exists()){
 System.out.println("file is already there");
 }else{
 System.out.println("Not find file ");
 }

I have found another way to read an image size (more generic). You can use ImageIO class in cooperation with ImageReaders. Here is the sample code:

private Dimension getImageDim(final String path) {
    Dimension result = null;
    String suffix = this.getFileSuffix(path);
    Iterator<ImageReader> iter = ImageIO.getImageReadersBySuffix(suffix);
    if (iter.hasNext()) {
        ImageReader reader = iter.next();
        try {
            ImageInputStream stream = new FileImageInputStream(new File(path));
            reader.setInput(stream);
            int width = reader.getWidth(reader.getMinIndex());
            int height = reader.getHeight(reader.getMinIndex());
            result = new Dimension(width, height);
        } catch (IOException e) {
            log(e.getMessage());
        } finally {
            reader.dispose();
        }
    } else {
        log("No reader found for given format: " + suffix));
    }
    return result;
}

Note that getFileSuffix is method that returns extension of path without "." so e.g.: png, jpg etc. Example implementation is:

private String getFileSuffix(final String path) {
    String result = null;
    if (path != null) {
        result = "";
        if (path.lastIndexOf('.') != -1) {
            result = path.substring(path.lastIndexOf('.'));
            if (result.startsWith(".")) {
                result = result.substring(1);
            }
        }
    }
    return result;
}

This solution is very quick as only image size is read from the file and not the whole image. I tested it and there is no comparison to ImageIO.read performance. I hope someone will find this useful.

You can to use Count Lines of Code (CLOC)

On Settings -> External Tools add a new tool

• Name: Count Lines of Code
• Group: Statistics
• Program: path/to/cloc
• Parameters: $ProjectFileDir$ or $FileParentDir$

For what it's worth, I've run into this on what was previously working code. I had added SELECT statements in a trigger for debug testing and forgot to remove them. Entity Framework / MVC doesnt play nice when other stuff is output to the "grid". Make sure to check for any rogue queries and remove them.

The day C++ coders agree on The Way, lambs will lie down with lions, Palestinians will embrace Israelis, and cats and dogs will be allowed to marry.

The separation between .h and .cpp files is mostly arbitrary at this point, a vestige of compiler optimizations long past. To my eye, declarations belong in the header and definitions belong in the implementation file. But, that's just habit, not religion.

Alex' comment looks good but I was still confused with using range. The following worked for me while working on a for condition using length within range.

{% for i in range(0,(nums['list_users_response']['list_users_result']['users'])| length) %}
<li>    {{ nums['list_users_response']['list_users_result']['users'][i]['user_name'] }} </li>
{% endfor %}

Use setState in your view to change employed property of state. This is example of React render engine.

 someFunctionWhichChangeParamEmployed(isEmployed) {
      this.setState({
          employed: isEmployed
      });
 }

 getInitialState() {
      return {
          employed: true
      }
 },

 render(){
    if (this.state.employed) {
        return (
            <div>
                <MyInput ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div>
                <span>Diff me!</span>
                <MyInput ref="unemployment-reason" name="unemployment-reason" />
                <MyInput ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

This would also happen when you are trying to restore a newer version backup in a older SQL database. For example when you try to restore a DB backup that is created in 2012 with 110 compatibility and you are trying to restore it in 2008 R2.

Date mDate = new Date(System.currentTimeMillis());
mDate.getMonth() + 1

The returned value starts from 0, so you should add one to the result.

Your question is already answered here :

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Also, a good link on what happens if we try to include our class file in rt.jar.

Yes, given an array, array, and a value, item to search for, you can use np.where as:

itemindex = numpy.where(array==item)

The result is a tuple with first all the row indices, then all the column indices.

For example, if an array is two dimensions and it contained your item at two locations then

array[itemindex[0][0]][itemindex[1][0]]

would be equal to your item and so would be:

array[itemindex[0][1]][itemindex[1][1]]

Now with use of this library High Quality Videos Lossing Audio so i use the MediaMuxer for Murging Audio and Video for Final Output

https://stackoverflow.com/a/15240012/9909365

Why the previous answer not worked

 Pattern p2 = Pattern.compile("sig=(.*?)[&]");
        Matcher m2 = p2.matcher(url);
        String sig = null;
        if (m2.find()) {
            sig = m2.group(1);
        }

As of November 2016, this is a little rough around the edges, but displays the basic principle. The url_encoded_fmt_stream_map today does not have a space after the colon (better make this optional) and "sig" has been changed to "signature"

and while i am debuging the code i found the new keyword its signature&s in many video's URL

Some time This Code Not worked proper

Same-origin policy

https://en.wikipedia.org/wiki/Same-origin_policy

https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1]. 

Ref : https://superuser.com/questions/773719/how-do-all-of-these-save-video-from-youtube-services-work/773998#773998

url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts              // DASH: contains video or audio stream

Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this

url  // direct HTTP link to a video
itag // code specifying the quality
s    // signature, security measure to counter downloading

Each URL will be encoded so you will need to decode them. Now the tricky part.

YouTube has at least 3 security levels for their videos

unsecured // as expected, you can download these with just the unencoded URL
s         // see below
RTMPE     // uses "rtmpe://" protocol, no known method for these

The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.

The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as

AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this

function mo(a) {
  a = a.split("");
  a = lo.rw(a, 1);
  a = lo.rw(a, 32);
  a = lo.IC(a, 1);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 44);
  return a.join("")
}

This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as

http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js

this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header

Access-Control-Allow-Origin: http://www.youtube.com

and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests

Access-Control-Allow-Origin: *

So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.

The problem was that the async keyword needs to appear before the lambda, not before the body:

db.Groups.ToList().ForEach(async (i) => {
    await GetAdminsFromGroup(i.Gid);
});

In Swift 3.0 :

var imageView : UIImageView
    imageView  = UIImageView(frame:CGRect(x:10, y:50, width:100, height:300));
    imageView.image = UIImage(named:"Test.jpeg")
    self.view.addSubview(imageView)

You must give a name to your submit button

<input type="submit" value"Submit" name="login">

Then you can call the button with $_POST['login']

with templates

#include <iostream>

// d = decimal places
template<int d> 
std::ostream& fixed(std::ostream& os){
    os.setf(std::ios_base::fixed, std::ios_base::floatfield); 
    os.precision(d); 
    return os; 
}

int main(){
    double d = 122.345;
    std::cout << fixed<2> << d;
}

similar for scientific as well, with a width option also (useful for columns)

// d = decimal places
template<int d> 
std::ostream& f(std::ostream &os){
    os.setf(std::ios_base::fixed, std::ios_base::floatfield); 
    os.precision(d); 
    return os; 
}

// w = width, d = decimal places
template<int w, int d> 
std::ostream& f(std::ostream &os){
    os.setf(std::ios_base::fixed, std::ios_base::floatfield); 
    os.precision(d); 
    os.width(w);
    return os; 
}

// d = decimal places
template<int d> 
std::ostream& e(std::ostream &os){
    os.setf(std::ios_base::scientific, std::ios_base::floatfield); 
    os.precision(d); 
    return os; 
}

// w = width, d = decimal places
template<int w, int d> 
std::ostream& e(std::ostream &os){
    os.setf(std::ios_base::scientific, std::ios_base::floatfield); 
    os.precision(d); 
    os.width(w);
    return os; 
}

int main(){
    double d = 122.345;
    std::cout << f<10,2> << d << '\n'
        << e<10,2> << d << '\n';
}

The slightly modified version of COPY below worked better for me, where I specify the CSV format. This format treats backslash characters in text without any fuss. The default format is the somewhat quirky TEXT.

COPY myTable FROM '/path/to/file/on/server' ( FORMAT CSV, DELIMITER('|') );

function isValidDate(date) {
        var valid = true;

        date = date.replace('/-/g', '');

        var month = parseInt(date.substring(0, 2),10);
        var day   = parseInt(date.substring(2, 4),10);
        var year  = parseInt(date.substring(4, 8),10);

        if(isNaN(month) || isNaN(day) || isNaN(year)) return false;

        if((month < 1) || (month > 12)) valid = false;
        else if((day < 1) || (day > 31)) valid = false;
        else if(((month == 4) || (month == 6) || (month == 9) || (month == 11)) && (day > 30)) valid = false;
        else if((month == 2) && (((year % 400) == 0) || ((year % 4) == 0)) && ((year % 100) != 0) && (day > 29)) valid = false;
        else if((month == 2) && ((year % 100) == 0) && (day > 29)) valid = false;
        else if((month == 2) && (day > 28)) valid = false;

    return valid;
}

This checks for valid days in each month and for valid leap year days.

If you used the auth scaffolding in 5.5 simply direct your href to:

{{ route('logout') }}

There is no need to alter any routes or controllers.

Download page for python-mysqldb. The page includes binaries for 32 and 64 bit versions of for Python 2.5, 2.6 and 2.7.

There's also discussion on getting rid of the deprecation warning.

UPDATE: This is an old answer. Currently, I would recommend using PyMySQL. It's pure python, so it supports all OSes equally, it's almost a drop-in replacement for mysqldb, and it also works with python 3. The best way to install it is using pip. You can install it from here (more instructions here), and then run:

pip install pymysql

from tkinter import *
import os

root = Tk()
file = filedialog.askdirectory()
changed_dir = os.listdir(file)
print(changed_dir)
root.mainloop()

You can use FolderBrowserDialog instead of FileDialog and get the path from the OK result.

FolderBrowserDialog browser = new FolderBrowserDialog();
string tempPath ="";

if (browser.ShowDialog() == DialogResult.OK)
{
  tempPath  = browser.SelectedPath; // prints path
}

It is not listed as a function in dplyr (yet): http://cran.rstudio.org/web/packages/dplyr/dplyr.pdf

None of these solutions really met my expectations. I wanted to subclass the TextField since I don't want to set the border manually all the time. I also wanted to change the border color e.g. for an error. So here's my solution with Anchors:

class CustomTextField: UITextField {

    var bottomBorder = UIView()

    override func awakeFromNib() {

            // Setup Bottom-Border

            self.translatesAutoresizingMaskIntoConstraints = false

            bottomBorder = UIView.init(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
            bottomBorder.backgroundColor = UIColor(rgb: 0xE2DCD1) // Set Border-Color
            bottomBorder.translatesAutoresizingMaskIntoConstraints = false

            addSubview(bottomBorder)

            bottomBorder.bottomAnchor.constraint(equalTo: bottomAnchor).isActive = true
            bottomBorder.leftAnchor.constraint(equalTo: leftAnchor).isActive = true
            bottomBorder.rightAnchor.constraint(equalTo: rightAnchor).isActive = true
            bottomBorder.heightAnchor.constraint(equalToConstant: 1).isActive = true // Set Border-Strength

    }
}

---- Optional ----

To change the color add sth like this to the CustomTextField Class:

@IBInspectable var hasError: Bool = false {
    didSet {

        if (hasError) {

            bottomBorder.backgroundColor = UIColor.red

        } else {

            bottomBorder.backgroundColor = UIColor(rgb: 0xE2DCD1)

        }

    }
}

And to trigger the Error call this after you created an instance of CustomTextField

textField.hasError = !textField.hasError

Hope it helps someone ;)

Use https://github.com/swordray/UIButtonSetBackgroundColorForState

Add to Podfile using CocoaPods

pod "UIButtonSetBackgroundColorForState"

Swift

button.setBackgroundColor(.red, forState: .highlighted)

Objective-C

[button setBackgroundColor:[UIColor redColor] forState:UIControlStateHighlighted];

I have always used the following:

If Request.QueryString("MyQueryString") IsNot Nothing Then

But only because syntactically it reads better.

When testing for a valid QueryString entry I also use the following:

If Not String.IsNullOrEmpty(Request.QueryString("MyQueryString")) Then

These are just the methods I have always used so I could not justify their usage other than they make the most sense to me when reading back code.

use fwrite() instead of file_put_contents()

The cross-browser solution without DOM manipulation given above does not work because it gives the first matching rule, not the last. The last matching rule is the one which applies. Here is a working version:

function getStyleRuleValue(style, selector) {
  let value = null;
  for (let i = 0; i < document.styleSheets.length; i++) {
    const mysheet = document.styleSheets[i];
    const myrules = mysheet.cssRules ? mysheet.cssRules : mysheet.rules;
    for (let j = 0; j < myrules.length; j++) {
      if (myrules[j].selectorText && 
          myrules[j].selectorText.toLowerCase() === selector) {
        value =  myrules[j].style[style];
      }
    }
  }
  return value;
}  

However, this simple search will not work in case of complex selectors.

if anyone is trying to nest a <mat-radio-group> inside a <mat-form-field> like below, you will get this error

                <mat-radio-group aria-label="Image Position" [(ngModel)]="section.field_1">
                    <mat-radio-button value="left">Left</mat-radio-button>
                    <mat-radio-button value="right">Right</mat-radio-button>
                </mat-radio-group>
            </mat-form-field>

remove the parent <mat-form-field> tags

In C# running this

UnicodeEncoding encoding = new UnicodeEncoding();
byte[] bytes = encoding.GetBytes("Hello");

Will create an array with

72,0,101,0,108,0,108,0,111,0

For a character which the code is greater than 255 it will look like this

If you want a very similar behavior in JavaScript you can do this (v2 is a bit more robust solution, while the original version will only work for 0x00 ~ 0xff)

var str = "Hello?";_x000D_
var bytes = []; // char codes_x000D_
var bytesv2 = []; // char codes_x000D_
_x000D_
for (var i = 0; i < str.length; ++i) {_x000D_
  var code = str.charCodeAt(i);_x000D_
  _x000D_
  bytes = bytes.concat([code]);_x000D_
  _x000D_
  bytesv2 = bytesv2.concat([code & 0xff, code / 256 >>> 0]);_x000D_
}_x000D_
_x000D_
// 72, 101, 108, 108, 111, 31452_x000D_
console.log('bytes', bytes.join(', '));_x000D_
_x000D_
// 72, 0, 101, 0, 108, 0, 108, 0, 111, 0, 220, 122_x000D_
console.log('bytesv2', bytesv2.join(', '));

java.time

I should like to contribute the modern answer. The SimpleDateFormat class is notoriously troublesome, and while it was reasonable to fight one’s way through with it when this question was asked six and a half years ago, today we have much better in java.time, the modern Java date and time API. SimpleDateFormat and its friend Date are now considered long outdated, so don’t use them anymore.

    DateTimeFormatter monthFormatter = DateTimeFormatter.ofPattern("MM/uuuu");
    String dateformat = "2012-11-17T00:00:00.000-05:00";
    OffsetDateTime dateTime = OffsetDateTime.parse(dateformat);
    String monthYear = dateTime.format(monthFormatter);
    System.out.println(monthYear);

Output:

11/2012

I am exploiting the fact that your string is in ISO 8601 format, the international standard, and that the classes of java.time parse this format as their default, that is, without any explicit formatter. It’s stil true what the other answers say, you need to parse the original string first, then format the resulting date-time object into a new string. Usually this requires two formatters, only in this case we’re lucky and can do with just one formatter.

What went wrong in your code

• As others have said, SimpleDateFormat.format cannot accept a String argument, also when the parameter type is declared to be Object.
• Because of the exception you didn’t get around to discovering: there is also a bug in your format pattern string, mm/yyyy. Lowercase mm os for minute of the hour. You need uppercase MM for month.
• Finally the Java naming conventions say to use a lowercase first letter in variable names, so use lowercase m in monthYear (also because java.time includes a MonthYear class with uppercase M, so to avoid confusion).

$.each(JSON.parse(result), function(i, item) {
    alert(item.number);
});

This function normalizes down all whitespace, including line breaks, to single spaces. Not exactly what the original question asked for, but likely to do exactly what is needed in many cases:

import org.apache.commons.lang3.StringUtils;

final String cleansedString = StringUtils.normalizeSpace(rawString);

To access services in two different namespaces you can use url like this:

HTTP://<your-service-name>.<namespace-with-that-service>.svc.cluster.local

To list out all your namespaces you can use:

kubectl get namespace

And for service in that namespace you can simply use:

kubectl get services -n <namespace-name>

this will help you.

It also has something to do with the version of JDK. If it does well in JDK6, maybe it will have the problem in JDK 7 described by you, because the implementation method in jdk 7 has been changed.

Look at this:

Description: The sorting algorithm used by java.util.Arrays.sort and (indirectly) by java.util.Collections.sort has been replaced. The new sort implementation may throw an IllegalArgumentException if it detects a Comparable that violates the Comparable contract. The previous implementation silently ignored such a situation. If the previous behavior is desired, you can use the new system property, java.util.Arrays.useLegacyMergeSort, to restore previous mergesort behaviour.

I don't know the exact reason. However, if you add the code before you use sort. It will be OK.

System.setProperty("java.util.Arrays.useLegacyMergeSort", "true");

public static long byteArrayToLong(byte[] bytes) {
    return ((long) (bytes[0]) << 56)
            + (((long) bytes[1] & 0xFF) << 48)
            + ((long) (bytes[2] & 0xFF) << 40)
            + ((long) (bytes[3] & 0xFF) << 32)
            + ((long) (bytes[4] & 0xFF) << 24)
            + ((bytes[5] & 0xFF) << 16)
            + ((bytes[6] & 0xFF) << 8)
            + (bytes[7] & 0xFF);
}

convert bytes array (long is 8 bytes) to long

talonmies' answer above is a fine way to abort an application in an assert-style manner.

Occasionally we may wish to report and recover from an error condition in a C++ context as part of a larger application.

Here's a reasonably terse way to do that by throwing a C++ exception derived from std::runtime_error using thrust::system_error:

#include <thrust/system_error.h>
#include <thrust/system/cuda/error.h>
#include <sstream>

void throw_on_cuda_error(cudaError_t code, const char *file, int line)
{
  if(code != cudaSuccess)
  {
    std::stringstream ss;
    ss << file << "(" << line << ")";
    std::string file_and_line;
    ss >> file_and_line;
    throw thrust::system_error(code, thrust::cuda_category(), file_and_line);
  }
}

This will incorporate the filename, line number, and an English language description of the cudaError_t into the thrown exception's .what() member:

#include <iostream>

int main()
{
  try
  {
    // do something crazy
    throw_on_cuda_error(cudaSetDevice(-1), __FILE__, __LINE__);
  }
  catch(thrust::system_error &e)
  {
    std::cerr << "CUDA error after cudaSetDevice: " << e.what() << std::endl;

    // oops, recover
    cudaSetDevice(0);
  }

  return 0;
}

The output:

$ nvcc exception.cu -run
CUDA error after cudaSetDevice: exception.cu(23): invalid device ordinal

A client of some_function can distinguish CUDA errors from other kinds of errors if desired:

try
{
  // call some_function which may throw something
  some_function();
}
catch(thrust::system_error &e)
{
  std::cerr << "CUDA error during some_function: " << e.what() << std::endl;
}
catch(std::bad_alloc &e)
{
  std::cerr << "Bad memory allocation during some_function: " << e.what() << std::endl;
}
catch(std::runtime_error &e)
{
  std::cerr << "Runtime error during some_function: " << e.what() << std::endl;
}
catch(...)
{
  std::cerr << "Some other kind of error during some_function" << std::endl;

  // no idea what to do, so just rethrow the exception
  throw;
}

Because thrust::system_error is a std::runtime_error, we can alternatively handle it in the same manner of a broad class of errors if we don't require the precision of the previous example:

try
{
  // call some_function which may throw something
  some_function();
}
catch(std::runtime_error &e)
{
  std::cerr << "Runtime error during some_function: " << e.what() << std::endl;
}

One thing I found is the path of your image must be relative to wherever the notebook was originally loaded from. if you cd to a different directory, such as Pictures your Markdown path is still relative to the original loading directory.

moment.js is great but sometimes you don't want to pull a large number of dependencies for simple things.

The following works as well:

var tzoffset = (new Date()).getTimezoneOffset() * 60000; //offset in milliseconds
var localISOTime = (new Date(Date.now() - tzoffset)).toISOString().slice(0, -1);
// => '2015-01-26T06:40:36.181'

The slice(0, -1) gets rid of the trailing Z which represents Zulu timezone and can be replaced by your own.

I found interest answer for compare performance String vs StringBuffer by Reggie Hutcherso Source: http://www.javaworld.com/javaworld/jw-03-2000/jw-0324-javaperf.html

Java provides the StringBuffer and String classes, and the String class is used to manipulate character strings that cannot be changed. Simply stated, objects of type String are read only and immutable. The StringBuffer class is used to represent characters that can be modified.

The significant performance difference between these two classes is that StringBuffer is faster than String when performing simple concatenations. In String manipulation code, character strings are routinely concatenated. Using the String class, concatenations are typically performed as follows:

 String str = new String ("Stanford  ");
 str += "Lost!!";

If you were to use StringBuffer to perform the same concatenation, you would need code that looks like this:

 StringBuffer str = new StringBuffer ("Stanford ");
 str.append("Lost!!");

Developers usually assume that the first example above is more efficient because they think that the second example, which uses the append method for concatenation, is more costly than the first example, which uses the + operator to concatenate two String objects.

The + operator appears innocent, but the code generated produces some surprises. Using a StringBuffer for concatenation can in fact produce code that is significantly faster than using a String. To discover why this is the case, we must examine the generated bytecode from our two examples. The bytecode for the example using String looks like this:

0 new #7 <Class java.lang.String>
3 dup 
4 ldc #2 <String "Stanford ">
6 invokespecial #12 <Method java.lang.String(java.lang.String)>
9 astore_1
10 new #8 <Class java.lang.StringBuffer>
13 dup
14 aload_1
15 invokestatic #23 <Method java.lang.String valueOf(java.lang.Object)>
18 invokespecial #13 <Method java.lang.StringBuffer(java.lang.String)>
21 ldc #1 <String "Lost!!">
23 invokevirtual #15 <Method java.lang.StringBuffer append(java.lang.String)>
26 invokevirtual #22 <Method java.lang.String toString()>
29 astore_1

The bytecode at locations 0 through 9 is executed for the first line of code, namely:

 String str = new String("Stanford ");

Then, the bytecode at location 10 through 29 is executed for the concatenation:

 str += "Lost!!";

Things get interesting here. The bytecode generated for the concatenation creates a StringBuffer object, then invokes its append method: the temporary StringBuffer object is created at location 10, and its append method is called at location 23. Because the String class is immutable, a StringBuffer must be used for concatenation.

After the concatenation is performed on the StringBuffer object, it must be converted back into a String. This is done with the call to the toString method at location 26. This method creates a new String object from the temporary StringBuffer object. The creation of this temporary StringBuffer object and its subsequent conversion back into a String object are very expensive.

In summary, the two lines of code above result in the creation of three objects:

1. A String object at location 0
2. A StringBuffer object at location 10
3. A String object at location 26

Now, let's look at the bytecode generated for the example using StringBuffer:

0 new #8 <Class java.lang.StringBuffer>
3 dup
4 ldc #2 <String "Stanford ">
6 invokespecial #13 <Method java.lang.StringBuffer(java.lang.String)>
9 astore_1
10 aload_1 
11 ldc #1 <String "Lost!!">
13 invokevirtual #15 <Method java.lang.StringBuffer append(java.lang.String)>
16 pop

The bytecode at locations 0 to 9 is executed for the first line of code:

 StringBuffer str = new StringBuffer("Stanford ");

The bytecode at location 10 to 16 is then executed for the concatenation:

 str.append("Lost!!");

Notice that, as is the case in the first example, this code invokes the append method of a StringBuffer object. Unlike the first example, however, there is no need to create a temporary StringBuffer and then convert it into a String object. This code creates only one object, the StringBuffer, at location 0.

In conclusion, StringBuffer concatenation is significantly faster than String concatenation. Obviously, StringBuffers should be used in this type of operation when possible. If the functionality of the String class is desired, consider using a StringBuffer for concatenation and then performing one conversion to String.

DateAndTime Reformat:

SELECT *, to_char( last_update, 'DD-MON-YYYY') as re_format from actor;

DEMO:

The query execution happens on all get methods like

$this->db->get('table_name');
$this->db->get_where('table_name',$array);

While last_query contains the last query which was run

$this->db->last_query();

If you want to get query string without execution you will have to do this. Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions

public function _compile_select($select_override = FALSE)
public function _reset_select()

Now you can write query and get it in a variable

$this->db->select('trans_id');
$this->db->from('myTable');
$this->db->where('code','B');
$subQuery = $this->db->_compile_select();

Now reset query so if you want to write another query the object will be cleared.

$this->db->_reset_select();

And the thing is done. Cheers!!! Note : While using this way you must use

$this->db->from('myTable')

instead of

$this->db->get('myTable')

which runs the query.

Take a look at this example

You have an error in your AJAX function, too much brackets, try instead $.ajax({

The show method does what you're looking for.

For example, given the following dataframe of 3 rows, I can print just the first two rows like this:

df = sqlContext.createDataFrame([("foo", 1), ("bar", 2), ("baz", 3)], ('k', 'v'))
df.show(n=2)

which yields:

+---+---+
|  k|  v|
+---+---+
|foo|  1|
|bar|  2|
+---+---+
only showing top 2 rows

Besides maintainability, the first way eliminates possibility of accident global variables creation:

(function () {
var variable1 = "Hello, World!" // Semicolon is missed out accidentally
var variable2 = "Testing..."; // Still a local variable
var variable3 = 42;
}());

While the second way is less forgiving:

(function () {
var variable1 = "Hello, World!" // Comma is missed out accidentally
    variable2 = "Testing...", // Becomes a global variable
    variable3 = 42; // A global variable as well
}());

Just use

File.Copy(filepath, "\\\\192.168.1.28\\Files");

A windows fileshare exposed via a UNC path is treated as part of the file system, and has nothing to do with the web.

The credentials used will be that of the ASP.NET worker process, or any impersonation you've enabled. If you can tweak those to get it right, this can be done.

You may run into problems because you are using the IP address instead of the server name (windows trust settings prevent leaving the domain - by using IP you are hiding any domain details). If at all possible, use the server name!

If this is not on the same windows domain, and you are trying to use a different domain account, you will need to specify the username as "[domain_or_machine]\[username]"

If you need to specify explicit credentials, you'll need to look into coding an impersonation solution.

you can use send instead of sendFile so you wont face with error! this works will help you!

Not a simple way, no.

Let's say that by "active" you mean "hasn't passed the maximum lifetime" and hasn't been explicitly destroyed and that you're using the default session handler.

• First, the maximum lifetime is defined as a php.ini config and is defined in terms of the last activity on the session. So the "expiry" mechanism would have to read the content of the sessions to determine the application-defined expiry.
• Second, you'd have to manually read the sessions directory and read the files, whose format I don't even know they're in.

If you really need this, you must implement some sort of custom session handler. See session_set_save_handler.

Take also in consideration that you'll have no feedback if the user just closes the browser or moves away from your site without explciitly logging out. Depending on much inactivity you consider the threshold to deem a session "inactive", the number of false positives you'll get may be very high.

This page is the first result for several search engines when looking for "git merge one branch into another". However, the original question is more specific and special case than the title would suggest.
It is also more complex than both the subject and the search expression. As such, this is a minimal but explanatory answer for the benefit of most visitors.

You mention the certificate is self-signed (by you)? Then you have two choices:

• add the certificate to your trust store (fetching cacert.pem from cURL website won't do anything, since it's self-signed)
• don't bother verifying the certificate: you trust yourself, don't you?

Here's a list of SSL context options in PHP: https://secure.php.net/manual/en/context.ssl.php

Set allow_self_signed if you import your certificate into your trust store, or set verify_peer to false to skip verification.

The reason why we trust a specific certificate is because we trust its issuer. Since your certificate is self-signed, no client will trust the certificate as the signer (you) is not trusted. If you created your own CA when signing the certificate, you can add the CA to your trust store. If your certificate doesn't contain any CA, then you can't expect anyone to connect to your server.

Nice that you brought this subject up.

This is an important thing/concept in git that a lof of git users would benefit from knowing. git rebase is a very powerful tool and enables you to squash commits together, remove commits etc. But as with any powerful tool, you basically need to know what you're doing or something might go really wrong.

When you are working locally and messing around with your local branches, you can do whatever you like as long as you haven't pushed the changes to the central repository. This means you can rewrite your own history, but not others history. By only messing around with your local stuff, nothing will have any impact on other repositories.

This is why it's important to remember that once you have pushed commits, you should not rebase them later on. The reason why this is important, is that other people might pull in your commits and base their work on your contributions to the code base, and if you later on decide to move that content from one place to another (rebase it) and push those changes, then other people will get problems and have to rebase their code. Now imagine you have 1000 developers :) It just causes a lot of unnecessary rework.

Updated on Nov 24, 2016: Elasticsearch 5 apparently has changed the way to configure the JVM. See this answer here. The answer below still applies to versions < 5.

tirdadc, thank you for pointing this out in your comment below.

I have a pastebin page that I share with others when wondering about memory and ES. It's worked OK for me: http://pastebin.com/mNUGQCLY. I'll paste the contents here as well:

References:

https://github.com/grigorescu/Brownian/wiki/ElasticSearch-Configuration http://www.elasticsearch.org/guide/reference/setup/installation/

Edit the following files to modify memory and file number limits. These instructions assume Ubuntu 10.04, may work on later versions and other distributions/OSes. (Edit: This works for Ubuntu 14.04 as well.)

/etc/security/limits.conf:

elasticsearch - nofile 65535
elasticsearch - memlock unlimited

/etc/default/elasticsearch (on CentOS/RH: /etc/sysconfig/elasticsearch ):

move.CompleteMove() does not return a value (perhaps it just prints something). Any method that does not return a value returns None, and you have assigned None to self.values.

Here is an example of this:

>>> def hello(x):
...    print x*2
...
>>> hello('world')
worldworld
>>> y = hello('world')
worldworld
>>> y
>>>

You'll note y doesn't print anything, because its None (the only value that doesn't print anything on the interactive prompt).

I think this is what are you looking for.

Sure you can:

I tested a simple solution that works for me! My javascript was in a js separate file. What I did is that I placed the javascript for the new element into the html that was loaded with ajax, and it works fine for me! This is for those having big files of javascript!!

I've found that using:

<img src="file://null">

will not make a request and validates correctly.

The browsers will simply block the access to the local file system.

But there might be an error displayed in console log in Chrome for example:

Not allowed to load local resource: file://null/

You may try this CSS. I have experienced it working always.

div {
  border-style: solid;
  padding: 5px;
}

table {
  width: 100%;
  word-break: break-all;
  border-style: solid;
}

<div style="width:200px;">
  <table>
    <tr>
      <th>Col 1</th>
      <th>Col 2</th>
      <th>Col 3</th>
      <th>Col 4</th>
      <th>Col 5</th>
    </tr>
    <tr>
      <td>data 1</td>
      <td>data 2</td>
      <td>data 3</td>
      <td>data 4</td>
      <td>data 5</td>
    </tr>
    <table>
</div>

on Wayland xcopy doesn't seem to work, use wl-clipboard instead. e.g. on fedora

sudo dnf install wl-clipboard

tree | wl-copy

wl-paste > file

Note that typeof always returns a string, and doesn't generate an error if the variable doesn't exist at all.

function A(val){
  if(typeof(val)  === "undefined") 
    //do this
  else
   //do this
}

After poking around it looks like Kelsey is correct.

Just use a comma or something and split it when you want to consume it.

Is this acceptable?

var child = document.createElement('div');
child.innerHTML = str;
child = child.firstChild;
document.getElementById('test').appendChild(child);

jsFiddle.

But, Neil's answer is a better solution.

What do you even want the result to be? 888888? If so, just remove the spaces with str_replace, then convert.

Shift-Tab
Ctrl-Tab
< key

depends on your editor.

CTRL-click works anywhere

CTRL-click that brings you to where clicked object is defined works everywhere - not only in Java classes and variables in Java code, but in Spring configuration (you can click on class name, or property, or bean name), in Hibernate (you can click on property name or class, or included resource), you can navigate within one click from Java class to where it is used as Spring or Hibernate bean; clicking on included JSP or JSTL tag also works, ctrl-click on JavaScript variable or function brings you to the place it is defined or shows a menu if there are more than one place, including other .js files and JS code in HTML or JSP files.

Autocomplete for many languagues

Hibernate

Autocomplete in HSQL expressions, in Hibernate configuration (including class, property and DB column names), in Spring configuration

<property name="propName" ref="<hit CTRL-SPACE>"

and it will show you list of those beans which you can inject into that property.

Java

Very smart autocomplete in Java code:

interface Person {
    String getName();
    String getAddress();
    int getAge();
}
//---
Person p;
String name = p.<CTRL-SHIFT-SPACE>

and it shows you ONLY getName(), getAddress() and toString() (only they are compatible by type) and getName() is first in the list because it has more relevant name. Latest version 8 which is still in EAP has even more smart autocomplete.

interface Country{
}
interface Address {
    String getStreetAddress();
    String getZipCode();
    Country getCountry();
}
interface Person {
    String getName();
    Address getAddress();
    int getAge();
}
//--- 
Person p;
Country c = p.<CTRL-SHIFT-SPACE>

and it will silently autocomplete it to

Country c = p.getAddress().getCountry();

Javascript

Smart autocomplete in JavaScript.

function Person(name,address) {
    this.getName = function() { return name };
    this.getAddress = function() { return address };
}

Person.prototype.hello = function() {
    return "I'm " + this.getName() + " from " + this.get<CTRL-SPACE>;
}

and it shows ONLY getName() and getAddress(), no matter how may get* methods you have in other JS objects in your project, and ctrl-click on this.getName() brings you to where this one is defined, even if there are some other getName() functions in your project.

HTML

Did I mention autocomplete and ctrl-clicking in paths to files, like <script src="", <img src="", etc?

Autocomplete in HTML tag attributes. Autocomplete in style attribute of HTML tags, both attribute names and values. Autocomplete in class attributes as well.
Type <div class="<CTRL-SPACE> and it will show you list of CSS classes defined in your project. Pick one, ctrl-click on it and you will be redirected to where it is defined.

Easy own language higlighting

Latest version has language injection, so you can declare that you custom JSTL tag usually contains JavaScript and it will highlight JavaScript inside it.

<ui:obfuscateJavaScript>function something(){...}</ui:obfuscateJavaScript>

Indexed search across all project.

You can use Find Usages of any Java class or method and it will find where it is used including not only Java classes but Hibernate, Spring, JSP and other places. Rename Method refactoring renames method not only in Java classes but anywhere including comments (it can not be sure if string in comments is really method name so it will ask). And it will find only your method even if there are methods of another class with same name. Good source control integration (does SVN support changelists? IDEA support them for every source control), ability to create a patch with your changes so you can send your changes to other team member without committing them.

Improved debugger

When I look at HashMap in debugger's watch window, I see logical view - keys and values, last time I did it in Eclipse it was showing entries with hash and next fields - I'm not really debugging HashMap, I just want to look at it contents.

Spring & Hibernate configuration validation

It validates Spring and Hibernate configuration right when you edit it, so I do not need to restart server to know that I misspelled class name, or added constructor parameter so my Spring cfg is invalid.

Last time I tried, I could not run Eclipse on Windows XP x64.

and it will suggest you person.name or person.address. Ctrl-click on person.name and it will navigate you to getName() method of Person class.

Type Pattern.compile(""); put \\ there, hit CTRL-SPACE and see helpful hint about what you can put into your regular expression. You can also use language injection here - define your own method that takes string parameter, declare in IntelliLang options dialog that your parameter is regular expression - and it will give you autocomplete there as well. Needless to say it highlights incorrect regular expressions.

Other features

There are few features which I'm not sure are present in Eclipse or not. But at least each member of our team who uses Eclipse, also uses some merging tool to merge local changes with changes from source control, usually WinMerge. I never need it - merging in IDEA is enough for me. By 3 clicks I can see list of file versions in source control, by 3 more clicks I can compare previous versions, or previous and current one and possibly merge.

It allows to to specify that I need all .jars inside WEB-INF\lib folder, without picking each file separately, so when someone commits new .jar into that folder it picks it up automatically.

Mentioned above is probably 10% of what it does. I do not use Maven, Flex, Swing, EJB and a lot of other stuff, so I can not tell how it helps with them. But it does.

Lets make it very simple:

Maven Lifecycles: 1. Clean 2. Default (build) 3. Site

Maven Phases of the Default Lifecycle: 1. Validate 2. Compile 3. Test 4. Package 5. Verify 6. Install 7. Deploy

Note: Don't mix or get confused with maven goals with maven lifecycle.

See Maven Build Lifecycle Basics1

doesnt directly answer your question. But helpful for those who want to start something after some time.

Future.delayed(Duration(seconds: 1), () {
            print('yo hey');
          });

Here is some example code to help you get started:

package com.acme;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class FileArrayProvider {

    public String[] readLines(String filename) throws IOException {
        FileReader fileReader = new FileReader(filename);
        BufferedReader bufferedReader = new BufferedReader(fileReader);
        List<String> lines = new ArrayList<String>();
        String line = null;
        while ((line = bufferedReader.readLine()) != null) {
            lines.add(line);
        }
        bufferedReader.close();
        return lines.toArray(new String[lines.size()]);
    }
}

And an example unit test:

package com.acme;

import java.io.IOException;

import org.junit.Test;

public class FileArrayProviderTest {

    @Test
    public void testFileArrayProvider() throws IOException {
        FileArrayProvider fap = new FileArrayProvider();
        String[] lines = fap
                .readLines("src/main/java/com/acme/FileArrayProvider.java");
        for (String line : lines) {
            System.out.println(line);
        }
    }
}

Hope this helps.

I realize that this is an old question, but here's a plugin to address this issue that someone might find useful.

https://github.com/madbook/jquery.wait

lets you do this:

$('#myElement').addClass('load').wait(5000).addClass('done');

The reason why you should use .wait instead of .delay is because not all jquery functions are supported by .delay and that .delay only works with animation functions. For example delay does not support .addClass and .removeClass

Or you can use this function instead.

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

sleep(5000);

Disabling the Sync to VBlank checkbox in nvidia-settings (OpenGL Settings tab) does the trick for me.

In MSVC to suppress a particular warning it is enough to specify the it's number to compiler as /wd#. My CMakeLists.txt contains such the block:

If (MSVC)
    Set (CMAKE_EXE_LINKER_FLAGS "$ {CMAKE_EXE_LINKER_FLAGS} / NODEFAULTLIB: LIBCMT")
    Add_definitions (/W4 /wd4512 /wd4702 /wd4100 /wd4510 /wd4355 /wd4127)
    Add_definitions (/D_CRT_SECURE_NO_WARNINGS)
Elseif (CMAKE_COMPILER_IS_GNUCXX OR CMAKE_COMPILER_IS_GNUC)
    Add_definitions (-Wall -W -pedantic)
Else ()
    Message ("Unknown compiler")
Endif ()

Now I can not say what exactly /wd4512 /wd4702 /wd4100 /wd4510 /wd4355 /wd4127 mean, because I do not pay any attention to MSVC for three years, but they suppress superpedantic warnings that does not influence the result.

If you're trying to check if someone is 18 years of age, using timedelta will not work correctly on some edge cases because of leap years. For example, someone born on January 1, 2000, will turn 18 exactly 6575 days later on January 1, 2018 (5 leap years included), but someone born on January 1, 2001, will turn 18 exactly 6574 days later on January 1, 2019 (4 leap years included). Thus, you if someone is exactly 6574 days old, you can't determine if they are 17 or 18 without knowing a little more information about their birthdate.

The correct way to do this is to calculate the age directly from the dates, by subtracting the two years, and then subtracting one if the current month/day precedes the birth month/day.

Space char is hexadecimal 0x20, decimal 32 and octal \040.

>>> SPACE = 0x20
>>> a = chr(SPACE)
>>> type(a)
<class 'str'>
>>> print(f"'{a}'")
' '

Just use Task.Run

var task = Task.Run(() =>
{
    //this will already share scope with rawData, no need to use a placeholder
});

Or, if you would like to use it in a method and await the task later

public Task<T> SomethingAsync<T>()
{
    var task = Task.Run(() =>
    {
        //presumably do something which takes a few ms here
        //this will share scope with any passed parameters in the method
        return default(T);
    });

    return task;
}

A crude way to do it -

var sel = document.getElementById('select_id');
sel.addEventListener('click', function(el){
    var options = this.children;
    for(var i=0; i < this.childElementCount; i++){
        options[i].style.color = 'white';
    }
    var selected = this.children[this.selectedIndex];
        selected.style.color = 'red';
    }, false);

I tried almost all the options above, none of them worked for my scenario. Finally I was forced to uninstall IIS Express, re-start the machine, and install the same version again from Microsoft.

Anyway thanks for all the suggestions above.

What you are looking for is merging.

git merge master

With pull you fetch changes from a remote repository and merge them into the current branch.

You can also use google-collections (guava) Joiner class if you want to customize the print format

More precisely, you have to force the addition of the tag, then push with option --tags and -f:

git tag -f -a <tagname>
git push -f --tags
