Turns out string starting with a newline (or anything other than "<") is not considered HTML string in jQuery 1.9

http://stage.jquery.com/upgrade-guide/1.9/#jquery-htmlstring-versus-jquery-selectorstring

I have a simple and generic hack to perform key/value if statement instead of boolean-only in mustache (and in an extremely readable fashion!) :

function buildOptions (object) {
    var validTypes = ['string', 'number', 'boolean'];
    var value;
    var key;
    for (key in object) {
        value = object[key];
        if (object.hasOwnProperty(key) && validTypes.indexOf(typeof value) !== -1) {
            object[key + '=' + value] = true;
        }
    }
    return object;
}

With this hack, an object like this:

var contact = {
  "id": 1364,
  "author_name": "Mr Nobody",
  "notified_type": "friendship",
  "action": "create"
};

Will look like this before transformation:

var contact = {
  "id": 1364,
  "id=1364": true,
  "author_name": "Mr Nobody",
  "author_name=Mr Nobody": true,
  "notified_type": "friendship",
  "notified_type=friendship": true,
  "action": "create",
  "action=create": true
};

And your mustache template will look like this:

{{#notified_type=friendship}}
    friendship…
{{/notified_type=friendship}}

{{#notified_type=invite}}
    invite…
{{/notified_type=invite}}

Another difference between them is the size of the file:

• Mustache.js has 9kb,
• Handlebars.js has 86kb, or 18kb if using precompiled templates.

To see the performance benefits of Handlebars.js we must use precompiled templates.

Source: An Overview of JavaScript Templating Engines

Your else statement should look like this (note the ^):

{{^avatar}}
 ...
{{/avatar}}

In mustache this is called 'Inverted sections'.

Built-in support since Handlebars 1.0rc1

Support for this functionality has been added to Handlebars.js, so there is no more need for external helpers.

How to use it

For arrays:

{{#each myArray}}
    Index: {{@index}} Value = {{this}}
{{/each}}

For objects:

{{#each myObject}}
    Key: {{@key}} Value = {{this}}
{{/each}}

Note that only properties passing the hasOwnProperty test will be enumerated.

If you need nested objects to be converted as well.

# @fn       to_hash obj {{{
# @brief    Convert object to hash
#
# @return   [Hash] Hash representing converted object
#
def to_hash obj
  Hash[obj.instance_variables.map { |key|
    variable = obj.instance_variable_get key
    [key.to_s[1..-1].to_sym,
      if variable.respond_to? <:some_method> then
        hashify variable
      else
        variable
      end
    ]
  }]
end # }}}

To the response of James I will only change the sorting function to make it more universal. This way it will sort text alphabetical and numbers like numbers.

if( $.text([a]) == $.text([b]) )
    return 0;
if(isNaN($.text([a])) && isNaN($.text([b]))){
    return $.text([a]) > $.text([b]) ? 
       inverse ? -1 : 1
       : inverse ? 1 : -1;
}
else{
    return parseInt($.text([a])) > parseInt($.text([b])) ? 
      inverse ? -1 : 1
      : inverse ? 1 : -1;
}

It doesn't matter what your system uses as newlines if the content might be generated outside of the system.

I am amazed after receiving all of these answers, that no one has simply advised the use of the \R escape sequence. There is only one way that I would ever consider implementing this in one of my own projects. \R provides the most succinct and direct approach.

https://www.php.net/manual/en/regexp.reference.escape.php#:~:text=line%20break:%20matches%20\n,%20\r%20and%20\r\n

Code: (Demo)

$text = "one\ntwo\r\nthree\rfour\r\n\nfive";

var_export(preg_split('~\R~', $text));

Output:

array (
  0 => 'one',
  1 => 'two',
  2 => 'three',
  3 => 'four',
  4 => '',
  5 => 'five',
)

I've today made quite a few changes to my rails schema. I realised I needed an additional two models in a hierarchy and some others to be deleted. There were many little changes required to the models and controllers.

I added the two new models and created them, using:

rake db:migrate

Then I edited the schema.rb file. I manually removed the old models that were no longer required, changed the foreign key field as required and just reordered it a bit to make it clearer to me. I deleted all the migrations, and then re-ran the build via:

rake db:reset

It worked perfectly. All the data has to be reloaded, of course. Rails realised the migrations had been deleted and reset the high-water mark:

-- assume_migrated_upto_version(20121026094813, ["/Users/sean/rails/f4/db/migrate"])

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

add layout_gravity="center" or "center_horizontal" to the parent layout.

On a side note, your LinearLayout inside your TableRow seems un-necessary, as a TableRow is already an horizontal LinearLayout.

So interestingly enough this error "Transport endpoint is not connected" was caused by my having more than one Veracrypt device mounted. I closed the extra device and suddenly I had access to the drive. Hmm..

The man page for checkout: http://git-scm.com/docs/git-checkout

The man page for clone: http://git-scm.com/docs/git-clone

To sum it up, clone is for fetching repositories you don't have, checkout is for switching between branches in a repository you already have.

Note: for those who have a SVN/CVS background and new to Git, the equivalent of git clone in SVN/CVS is checkout. The same wording of different terms is often confusing.

I came here because currently the WordPress table block doesn't support the colspan parameter and i thought i will replace it using CSS. This was my solution, assuming that the columns are the same width:

table {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
table td {_x000D_
  width: 50%;_x000D_
  background: #dbdbdb;_x000D_
  text-align: center;_x000D_
}_x000D_
_x000D_
table tr:nth-child(2n+1) {_x000D_
  position:relative;_x000D_
  display:block;_x000D_
  height:20px;_x000D_
  background:green;_x000D_
}_x000D_
_x000D_
table tr:nth-child(2n+1) td {_x000D_
  position:absolute;_x000D_
  left:0;_x000D_
  right:-100%;_x000D_
  width: auto;_x000D_
  top:0;_x000D_
  bottom:0;_x000D_
  background:red;_x000D_
  text-align:center;_x000D_
}

<table>_x000D_
    <tr>_x000D_
        <td>row</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td>cell</td>_x000D_
        <td>cell</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_

</table>

following will show one table of dataset

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show

if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.

if two tables with same table schema

dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable

sample code to mode all tables

DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
     dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

The provided solutions do resolve the issue. However, they also impact all other textarea elements with the same styling. I had to solve this and just created a more specific selector. Here is what I came up with to prevent invasive changes.

.modal-content textarea.form-control {
    max-width: 100%;
}

While this selector may seem aggressive. It helps restrain the textarea into the content area of the modal itself.

Additionally, the min-width solution presented, above, works with basic bootstrap modals, though I had issues when using it with angular-ui-bootstrap modals.

Unlike stated previously 'preceding-sibling' is really the axis to use, not 'preceding' which does something completely different, it selects everything in the document that is before the start tag of the current node. (see http://www.w3schools.com/xpath/xpath_axes.asp)

Use print("use this bracket -sample text")

In Python 3 print "Hello world" gives invalid syntax error.

To display string content in Python3 have to use this ("Hello world") brackets.

If using VueJS, import all the js dependencies for jQuery extensions first, then import $ second...

import "../assets/js/jquery-2.2.3.min.js"
import "../assets/js/jquery-ui-1.12.1.min.js"
import "../assets/js/jquery.validate.min.js"
import $ from "jquery";

You then need to use jquery from a javascript function called from a custom wrapper defined globally in the VueJS prototype method.

This safeguards use of jQuery and jQuery UI from fighting with VueJS.

Vue.prototype.$fValidateTag = function( sTag, rRules ) 
{
    return ValidateTag( sTag, rRules );
};

function ValidateTag( sTag, rRules )
{
    Var rTagT = $( sTag );
    return rParentTag.validate( sTag, rRules );
}

It looks like ByRef needs to know the size of the parameter. A declaration of Dim last_name as string doesn't specify the size of the string so it takes it as an error. Before using Worksheets(data_sheet).Range("C2").Value = ProcessString(last_name) The last_name has to be declared as Dim last_name as string *10 ' size of string is up to you but must be a fix length

No need to change the function. Function doesn't take a fix length declaration.

I know this has already been answered, but seeing so many visits here I'd like to add one version that uses the SAMPLE clause but still allows to filter the rows first:

with cte1 as (
    select *
    from t_your_table
    where your_column = 'ABC'
)
select * from cte1 sample (5)

Note however that the base select needs a ROWID column, which means it may not work for some views for example.

childform = new Child();
childform.Show(this);

In event childform load

this.CenterToParent();

look at this url Android adb devices unauthorized else briefly do the following:

1. look for adbkey with not extension in the platform-tools/.android and delete this file
2. look at C:\Users\*username*\.android) and delete adbkey
3. C:\Windows\System32\config\systemprofile\.android and delete adbkey

You may find it in one of the directories above. Or just search adbkey in the Parent folders above then locate and delete.

If you simply want to set/use default profile at the time of making build through maven then, pass the argument -Dspring.profiles.active=test Just like

mvn clean install -Dspring.profiles.active=dev

Just don't anchor your pattern:

/Test/

The above regex will check for the literal string "Test" being found somewhere within it.

public static String getMd5OfFile(String filePath)
{
    String returnVal = "";
    try 
    {
        InputStream   input   = new FileInputStream(filePath); 
        byte[]        buffer  = new byte[1024];
        MessageDigest md5Hash = MessageDigest.getInstance("MD5");
        int           numRead = 0;
        while (numRead != -1)
        {
            numRead = input.read(buffer);
            if (numRead > 0)
            {
                md5Hash.update(buffer, 0, numRead);
            }
        }
        input.close();

        byte [] md5Bytes = md5Hash.digest();
        for (int i=0; i < md5Bytes.length; i++)
        {
            returnVal += Integer.toString( ( md5Bytes[i] & 0xff ) + 0x100, 16).substring( 1 );
        }
    } 
    catch(Throwable t) {t.printStackTrace();}
    return returnVal.toUpperCase();
}

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

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

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

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

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

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

/*link*/
$q.when(scope.regions).then(function(result) {
    console.log(result);
});

var Regions = $resource('mocks/regions.json');
$scope.regions = Regions.query().$promise.then(function(response) {
    return response;
});

You just need to initialize your view in onCreate() method and then in onCreateDialog() again before setView() and it should be work!

val error = JSONObject(callApi.errorBody()?.string() as String)
            CustomResult.OnError(CustomNotFoundError(userMessage = error["userMessage"] as String))

open class CustomError (
    val traceId: String? = null,
    val errorCode: String? = null,
    val systemMessage: String? = null,
    val userMessage: String? = null,
    val cause: Throwable? = null
)

    private val traceId: String? = null,
    private val errorCode: String? = null,
    private val systemMessage: String? = null,
    private val userMessage: String? = null,
    override val cause: Throwable? = null
) : Throwable(userMessage, cause) {
    fun toError(): CustomError = CustomError(traceId, errorCode, systemMessage, userMessage, cause)
}


class NetworkError(traceId: String? = null, errorCode: String? = null, systemMessage: String? = null, userMessage: String? = null, cause: Throwable? = null):
    CustomError(traceId, errorCode, systemMessage, userMessage?: "Usted no tiene conexión a internet, active los datos", cause)

class HttpError(traceId: String? = null, errorCode: String? = null, systemMessage: String? = null, userMessage: String? = null, cause: Throwable? = null):
    CustomError(traceId, errorCode, systemMessage, userMessage, cause)

class UnknownError(traceId: String? = null, errorCode: String? = null, systemMessage: String? = null, userMessage: String? = null, cause: Throwable? = null):
    CustomError(traceId, errorCode, systemMessage, userMessage?: "Unknown error", cause)

class CustomNotFoundError(traceId: String? = null, errorCode: String? = null, systemMessage: String? = null, userMessage: String? = null, cause: Throwable? = null):
    CustomError(traceId, errorCode, systemMessage, userMessage?: "Data not found", cause)`

The SetEnv.cmd script that the "SDK command prompt" shortcut runs checks for cl.exe in various places before setting up entries to add to PATH. So it fails to add anything if a native C compiler is not installed.

To fix that, apply the following patch to <SDK install dir>\Bin\SetEnv.cmd. This will also fix missing paths to other tools located in <SDK install dir>\Bin and subfolders. Of course, you can install the C compiler instead to work around this bug.

Thread.currentThread().getStackTrace();

is available since JDK1.5.

For an older version, you can redirect exception.printStackTrace() to a StringWriter() :

StringWriter sw = new StringWriter();
new Throwable("").printStackTrace(new PrintWriter(sw));
String stackTrace = sw.toString();

If you set numberOfLines to 0 (and the label to word wrap), the label will automatically wrap and use as many of lines as needed.

If you're editing a UILabel in IB, you can enter multiple lines of text by pressing option+return to get a line break - return alone will finish editing.

You can use:

((count = FIRSTV - SECONDV))

to avoid invoking a separate process, as per the following transcript:

pax:~$ FIRSTV=7
pax:~$ SECONDV=2
pax:~$ ((count = FIRSTV - SECONDV))
pax:~$ echo $count
5

This generally happens only when you are not controlling the value of the filed when the application started and after some event or some function fired or the state changed, you are now trying to control the value in input field.

This transition of not having control over the input and then having control over it is what causes the issue to happen in the first place.

The best way to avoid this is by declaring some value for the input in the constructor of the component. So that the input element has value from the start of the application.

If you define custom CSS you must set font-weight: 900; for some newer Font Awesome library (from version 5). Not setting this font-weight it may show squares.

Just for sake of completion, you can also do this:

array = []
array += [valueToBeInserted]

If it's a list of strings, this will also work:

array += 'string'

Here's how I do it, which I think is the most straightforward way to do it:

var x = 3.2;
int_part = Math.trunc(x); // returns 3
float_part = Number((x-int_part).toFixed(2)); // return 0.2

DF[:-n]

where n is the last number of rows to drop.

To drop the last row :

DF = DF[:-1]

Method that returns locale from string exists in commons-lang library: LocaleUtils.toLocale(localeAsString)

I just got the same error message with a couple projects after installing Visual Studio 2015 Update 3. For me, the solution was to install .NET Core

(Q1) How can I find the socket file?

The default location for the socket file is /tmp/mysql.sock, to find the socket file for your system use this.

mysqladmin variables | grep socket

If you have just installed MySql the mysql.sock file will not be created until the server is started. Use this command to start it.

sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

If prompted for a password you can pass the username root or other username like this. Terminal will prompt you for the password.

mysqladmin --user root --password variables | grep socket

(Q2) How can I refresh locate index

Refresh the locate db with this command.

sudo /usr/libexec/locate.updatedb

The running the impdp command to produce an sqlfile, you will need to run it as a user which has the DATAPUMP_IMP_FULL_DATABASE role.

Or... run it as a low privileged user and use the MASTER_ONLY=YES option, then inspect the master table. e.g.

select value_t 
from SYS_IMPORT_TABLE_01 
where name = 'CLIENT_COMMAND' 
and process_order = -59;

col object_name for a30
col processing_status head STATUS for a6
col processing_state head STATE for a5
select distinct
  object_schema,
  object_name,
  object_type,
  object_tablespace,
  process_order,
  duplicate,
  processing_status,
  processing_state
from sys_import_table_01
where process_order > 0
and object_name is not null
order by object_schema, object_name

So, to be clear, it's a lazy coding style. I prefer native types, given the choice; I'll take that extra bit of "noise" to ensure I'm writing and reading exactly what I think I am at code/debug time. * shrug *

You can use the REST-API's "Item last modified". From the docs, it retuns something like this:

GET /api/storage/libs-release-local/org/acme?lastModified
{
"uri": "http://localhost:8081/artifactory/api/storage/libs-release-local/org/acme/foo/1.0-SNAPSHOT/foo-1.0-SNAPSHOT.pom",
"lastModified": ISO8601
}

Example:

# Figure out the URL of the last item modified in a given folder/repo combination
url=$(curl \
    -H 'X-JFrog-Art-Api: XXXXXXXXXXXXXXXXXXXX' \
    'http://<artifactory-base-url>/api/storage/<repo>/<folder>?lastModified'  | jq -r '.uri')
# Figure out the name of the downloaded file
downloaded_filename=$(echo "${url}" | sed -e 's|[^/]*/||g')
# Download the file
curl -L -O "${url}"

I wrestled quite a while with the proper syntax for CREATE TEMPORARY TABLE SELECT. Having figured out a few things, I wanted to share the answers with the rest of the community.

Basic information about the statement is available at the following MySQL links:

CREATE TABLE SELECT and CREATE TABLE.

At times it can be daunting to interpret the spec. Since most people learn best from examples, I will share how I have created a working statement, and how you can modify it to work for you.

1. Add multiple indexes

   This statement shows how to add multiple indexes (note that index names - in lower case - are optional):

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (INDEX my_index_name (tag, time), UNIQUE my_unique_index_name (order_number))
   SELECT * FROM core.my_big_table
   WHERE my_val = 1
   

2. Add a new primary key:

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (PRIMARY KEY my_pkey (order_number),
   INDEX cmpd_key (user_id, time))
   SELECT * FROM core.my_big_table
   

3. Create additional columns

   You can create a new table with more columns than are specified in the SELECT statement. Specify the additional column in the table definition. Columns specified in the table definition and not found in select will be first columns in the new table, followed by the columns inserted by the SELECT statement.

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (my_new_id BIGINT NOT NULL AUTO_INCREMENT,  
   PRIMARY KEY my_pkey (my_new_id), INDEX my_unique_index_name (invoice_number))
   SELECT * FROM core.my_big_table
   

4. Redefining data types for the columns from SELECT

   You can redefine the data type of a column being SELECTed. In the example below, column tag is a MEDIUMINT in core.my_big_table and I am redefining it to a BIGINT in core.my_tmp_table.

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (tag BIGINT,
   my_time DATETIME,  
   INDEX my_unique_index_name (tag) )
   SELECT * FROM core.my_big_table
   

5. Advanced field definitions during create

   All the usual column definitions are available as when you create a normal table. Example:

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
   value BIGINT UNSIGNED NOT NULL DEFAULT 0 UNIQUE,
   location VARCHAR(20) DEFAULT "NEEDS TO BE SET",
   country CHAR(2) DEFAULT "XX" COMMENT "Two-letter country code",  
   INDEX my_index_name (location))
   ENGINE=MyISAM 
   SELECT * FROM core.my_big_table
   

I actually just wrote my own script for this purpose. It doesn't use Xcode. (It's based off a similar script in the Gambit Scheme project.)

Basically, it runs ./configure and make three times (for i386, armv7, and armv7s), and combines each of the resulting libraries into a fat lib.

This question is rooted in branch prediction models on CPUs. I'd recommend reading this paper:

Increasing the Instruction Fetch Rate via Multiple Branch Prediction and a Branch Address Cache

When you have sorted elements, the IR can not be bothered to fetch all CPU instructions, again and again. It fetches them from the cache.

You could also use the php native funcion get_browser()

IMPORTANT NOTE: You should have a browscap.ini file.

I had the same problem. My solution:

For Python 3

sudo apt-get install python3-pip

For Python 2

sudo apt-get install python-pip

No, JSFiddle doesn't have a download feature. However, it's not very difficult to get around that and save the contents of a fiddle anyway.

Since the time the accepted answer was posted, JSFiddle has made some recent UI and backend changes that affect the way a fiddle should be downloaded. Note the updated procedures below.

Simple Commandline Method

This method only downloads the fiddle's HTML, JavaScript, and CSS as a single file. The fiddle's external resources are not saved.

In the commandline shown below, fiddle_id refers to the ID number of the fiddle. For a fiddle with the URL "http://jsfiddle.net/<fiddle_user>/<fiddle_id>" or "http://jsfiddle.net/<fiddle_id>", only the fiddle_id is needed. The fiddle_user is unimportant.

At a shell prompt, enter the single commandline:

fiddleId=fiddle_id; curl "http://fiddle.jshell.net/${fiddleId}/show/" -H "Referer: http://fiddle.jshell.net/${fiddleId}/" --output "${fiddleId}.html"

The fiddle will be saved to a file named "fiddle_id.html".

Longer Browser Method

This method downloads the fiddle as well as its external resources. The steps given are based on using Google Chrome. Using other web browsers should work as well, but they may use different filenames.

1. Select the "Share/Embed" menu/link at the top of the JSFiddle edit page. In the dialog box that appears, copy the URL shown in the "Share full screen result" field. It will be of the form "http://jsfiddle.net/<fiddle_user>/<fiddle_id>/embedded/result/" or "http://jsfiddle.net/<fiddle_id>/embedded/result/".
2. Open a new browser window and paste in the URL copied in the previous step. Load that page.
3. Use your browser's save feature to save the page and all of its resources to your local computer. To save all the resources using Google Chrome, for example, be sure to select "Webpage, Complete" in the "Format" menu. Be sure to specify a name for the page. Let's say it's named "fiddle.html" for this example.
4. After the page is saved to your computer, you will have the "fiddle.html" file and a directory named "fiddle_files". The file "fiddle.html" is the wrapper page that JSFiddle uses to display a header with a "Result" title and other links. It will load your fiddle in an iframe element. For the most part, this file can be ignored or even deleted. Your fiddle's HTML, JavaScript, and CSS content will all be saved in the "fiddle_files" directory as a single file named "saved_resource.html".
5. Copy "fiddle_files/saved_resource.html" to wherever you'd like to use it. If your fiddle included items under "External Resources", those will also appear in the "fiddle_files" directory. Be sure to copy those files to the same place to which you copied "saved_resource.html", because the HTML file will refer to those resources using relative URLs.

As mentioned earlier, other browsers may name the files differently when they are saved. For example, Firefox names the combined HTML/JS/CSS file "fiddle_files/a.html".

is so easy You can use [phpy - library for php][1] php file

<?php
  require_once "vendor/autoload.php";

  use app\core\App;

  $app = new App();
  $python = $app->python;
  $output = $python->set(your python path)->send(data..)->gen();
  var_dump($ouput);

python file:

import include.library.phpy as phpy
print(phpy.get_data(number of data , first = 1 , two =2 ...))

you can see also example in github page [1]: https://github.com/Raeen123/phpy

Old post, but I thought I would share my solution because there aren't many solutions out there for this issue.

If you're running an old Windows Server 2003 machine, you likely need to install a hotfix (KB938397).

This problem occurs because the Cryptography API 2 (CAPI2) in Windows Server 2003 does not support the SHA2 family of hashing algorithms. CAPI2 is the part of the Cryptography API that handles certificates.

https://support.microsoft.com/en-us/kb/938397

For whatever reason, Microsoft wants to email you this hotfix instead of allowing you to download directly. Here's a direct link to the hotfix from the email:

http://hotfixv4.microsoft.com/Windows Server 2003/sp3/Fix200653/3790/free/315159_ENU_x64_zip.exe

This works everywhere including Safari 5 and Firefox 5 on OS X.

UPDATE: Fx Quantum (54) has no need for the replace, but Safari 11 is still not happy unless you convert as below

var date_test = new Date("2011-07-14 11:23:00".replace(/-/g,"/"));_x000D_
console.log(date_test);

FIDDLE

You can only select columns that are in the group or used in an aggregate function. You can use a join to get this working

select s1.* 
from sensorTable s1
inner join 
(
  SELECT sensorID, max(timestamp) as mts
  FROM sensorTable 
  GROUP BY sensorID 
) s2 on s2.sensorID = s1.sensorID and s1.timestamp = s2.mts

What Worked for me, while having I have more than 1 user on my computer.

Using terminal:

• Running brew doctor
  • Seeing multiple /usr/local/... isn't writable error's
• Disabling Mac's System Integrity Protection: https://apple.stackexchange.com/a/208481/55628
• Run the following
• sudo chown -R $(whoami) /usr/local/*
• brew doctor && brew upgrade && brew doctor

Running Macbook Pro OSX High Sierra (version 10.13.3.)

EDIT 1:

FYI - Please be Advised this causes an issue with running MySQL on your MAC.

To be able to start my local server, I had to run:

sudo chown -R mysql:mysql /usr/local/mysql/data

After you run this you can start your local MySQL Server.

You can also collect with an appropriate summing collector like Collectors#summingInt(ToIntFunction)

Returns a Collector that produces the sum of a integer-valued function applied to the input elements. If no elements are present, the result is 0.

For example

Stream<Obj> filtered = list.stream().filter(o -> o.field > 10);
int sum = filtered.collect(Collectors.summingInt(o -> o.field));

My naive assumption was that the size of scroll pane will be determined automatically...

The only solution that actually worked for me was explicitly seeting bounds of JScrollPane:

import javax.swing.*;

public class MyFrame extends JFrame {

    public MyFrame()
    {
        setBounds(100, 100, 491, 310);
        getContentPane().setLayout(null);

        JTextArea textField = new JTextArea();
        textField.setEditable(false);

        String str = "";
        for (int i = 0; i < 50; ++i)
            str += "Some text\n";
        textField.setText(str);

        JScrollPane scroll = new JScrollPane(textField);
        scroll.setBounds(10, 11, 455, 249);                     // <-- THIS

        getContentPane().add(scroll);
        setLocationRelativeTo ( null );
    }
}

Maybe it will help some future visitors :)

You can do the following:

bash -c "nano index.html"

The command above opens the index.html file with the nano editor within Powershell.

Alternatively, you can use the vim editor with the following command

bash -c "vi index.html"

Set the GroupName property of both radio buttons to the same value. You could also try using a RadioButtonGroup, which does this for you automatically.

I posted some code in answer to a related question on StackOverflow:

Sorting a multidimensionnal array in VBA

The code samples in that thread include:

1. A vector array Quicksort;
2. A multi-column array QuickSort;
3. A BubbleSort.

Alain's optimised Quicksort is very shiny: I just did a basic split-and-recurse, but the code sample above has a 'gating' function that cuts down on redundant comparisons of duplicated values. On the other hand, I code for Excel, and there's a bit more in the way of defensive coding - be warned, you'll need it if your array contains the pernicious 'Empty()' variant, which will break your While... Wend comparison operators and trap your code in an infinite loop.

Note that quicksort algorthms - and any recursive algorithm - can fill the stack and crash Excel. If your array has fewer than 1024 members, I'd use a rudimentary BubbleSort.

Public Sub QuickSortArray(ByRef SortArray As Variant, _
                                Optional lngMin As Long = -1, _ 
                                Optional lngMax As Long = -1, _ 
                                Optional lngColumn As Long = 0)

You can figure out which proxy server you're using by accessing some websites with a browser and then running the DOS command:

netstat

and you'll see some connections in the Foreign Address column on port 80 or 8080 (common proxy server ports). Ideally you will be able to identify the proxy server by its naming convention.

You can use this module which is easy to use: https://github.com/halilb/react-native-textinput-effects

After some thinking i came up with this solution:

 LENGTHB(TO_CHAR(SUBSTR(<CLOB-Column>,1,4000)))

SUBSTR returns only the first 4000 characters (max string size)

TO_CHAR converts from CLOB to VARCHAR2

LENGTHB returns the length in Bytes used by the string.

The default iterator for the JObject is as a dictionary iterating over key/value pairs.

JObject obj = JObject.Parse(response);
foreach (var pair in obj) {
    Console.WriteLine (pair.Key);
}

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

from the command line: for /R /D %1 in (*) do rd "%1"

in a batch file for /R /D %%1 in (*) do rd "%%1"

I don't know if it's documented as such, but it works in W2K, XP, and Win 7. And I don't know if it will always work, but it won't ever delete files by accident.

Set the iframe to the appropriate width and height and set the scrolling attribute to "no".

If the area you want is not in the top-left portion of the page, you can scroll the content to the appropriate area. Refer to this question:

Scrolling an iframe with javascript?

I believe you'll only be able to scroll it if both pages are on the same domain.

I have a dialog box that uses the datepicker on it. It was always hidden. When I adjusted the z-index, the field on the lower form always showed up on the dialog.

I used a combination of solutions that I saw to resolve the issue.

$('.ui-datepicker', $form).datepicker({
                showButtonPanel: true,
                changeMonth: true,
                changeYear: true,
                dateFormat: "yy-M-dd",
                beforeShow: function (input) {
                    $(input).css({
                        "position": "relative",
                        "z-index": 999999
                    });
                },
                onClose: function () { $('.ui-datepicker').css({ 'z-index': 0  } ); }                    
            });

The before show ensures that datepicker always is on top when selected, but the onClose ensures that the z-index of the field gets reset so that it doesn't overlap on any dialogs opened later with a different datepicker.

Convert Lists to Collection and use removeAll

    Collection<String> listOne = new ArrayList(Arrays.asList("a","b", "c", "d", "e", "f", "g"));
    Collection<String> listTwo = new ArrayList(Arrays.asList("a","b",  "d", "e", "f", "gg", "h"));


    List<String> sourceList = new ArrayList<String>(listOne);
    List<String> destinationList = new ArrayList<String>(listTwo);


    sourceList.removeAll( listTwo );
    destinationList.removeAll( listOne );



    System.out.println( sourceList );
    System.out.println( destinationList );

Output:

[c, g]
[gg, h]

[EDIT]

other way (more clear)

  Collection<String> list = new ArrayList(Arrays.asList("a","b", "c", "d", "e", "f", "g"));

    List<String> sourceList = new ArrayList<String>(list);
    List<String> destinationList = new ArrayList<String>(list);

    list.add("boo");
    list.remove("b");

    sourceList.removeAll( list );
    list.removeAll( destinationList );


    System.out.println( sourceList );
    System.out.println( list );

Output:

[b]
[boo]

@if(@Model.AuditDate.Value != null){@Model.AuditDate.Value.ToString("dd/MM/yyyy")}
else {@Html.DisplayFor(Model => Model.AuditDate)}

Explanation: If the AuditDate value is not null then it will format the date to dd/MM/yyyy, otherwise leave it as it is because it has no value.

One solution would be to create a Calendar instance, and start a cycle, increasing it's Calendar.DATE field until it reaches the desired date. Also, on each step you should create a Date instance (with corresponding parameters), and put it to your list.

Some dirty code:

    public List<Date> getDatesBetween(final Date date1, final Date date2) {
    List<Date> dates = new ArrayList<Date>();

    Calendar calendar = new GregorianCalendar() {{
        set(Calendar.YEAR, date1.getYear());
        set(Calendar.MONTH, date1.getMonth());
        set(Calendar.DATE, date1.getDate());
    }};

    while (calendar.get(Calendar.YEAR) != date2.getYear() && calendar.get(Calendar.MONTH) != date2.getMonth() && calendar.get(Calendar.DATE) != date2.getDate()) {
        calendar.add(Calendar.DATE, 1);
        dates.add(new Date(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DATE)));
    }

    return dates;
}

In View use this:

form.field.errors|striptags

for getting validation messages without html

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

Not very readable, but effective, has no dependencies and runs with any java version

byte[] buffer = new byte[1024];
for (int n; (n = inputStream.read(buffer)) != -1; outputStream.write(buffer, 0, n));

You must set the image rendering mode to UIImageRenderingModeAlwaysTemplate in order to have the tintColor affect the UIImage. Here is the solution in Swift:

let image = UIImage(named: "image-name")
let button = UIButton()
button.setImage(image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), forState: .Normal)
button.tintColor = UIColor.whiteColor()

SWIFT 4x

button.setImage(image.withRenderingMode(UIImage.RenderingMode.alwaysTemplate), for: .normal)
button.tintColor = UIColor.blue

In the example above. For me, this if($response.success==false) thing does not work. Here is correct PHP code:

$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = "--your_key--";
$response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']."&remoteip=".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);

if (isset($data->success) AND $data->success==true) {
            // everything is ok!
} else {
            // spam
}

var secondEmails = (from item in list2
                    select new { Email = item.Email }
                   ).ToList();

var matches = from item in list1
              where !secondEmails.Contains(item.Email)
              select new {Email = item.Email};

I use MacTex, and my editor is TexShop. It probably has to do with what compiler you are using. When I use pdftex, the command:

\includegraphics[height=60mm, width=100mm]{number2.png}

works fine, but when I use "Tex and Ghostscript", I get the same error as you, about not being able to get the size information. Use pdftex.

Incidentally, you can change this in TexShop from the "Typeset" menu.

Hope this helps.

You need to add a vertical-align property to your two child div's.

If .small is always shorter, you need only apply the property to .small. However, if either could be tallest then you should apply the property to both .small and .big.

.container{ 
    border: 1px black solid;
    width: 320px;
    height: 120px;    
}

.small{
    display: inline-block;
    width: 40%;
    height: 30%;
    border: 1px black solid;
    background: aliceblue; 
    vertical-align: top;   
}

.big {
    display: inline-block;
    border: 1px black solid;
    width: 40%;
    height: 50%;
    background: beige; 
    vertical-align: top;   
}

Vertical align affects inline or table-cell box's, and there are a large nubmer of different values for this property. Please see https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align for more details.

I have found something that Actually works in both FireFox and IE, on Elizabeth Castro's site (thanks to the link on this site) - I have tried all other versions here, but could not make them work in both the browsers

Another important consideration: The Elvis Operator breaks the Zend Opcache tokenization process. I found this the hard way! While this may have been fixed in later versions, I can confirm this problem exists in PHP 5.5.38 (with in-built Zend Opcache v7.0.6-dev).

If you find that some of your files 'refuse' to be cached in Zend Opcache, this may be one of the reasons... Hope this helps!

You have to do this:

class Bar : public Foo
{
    // ...
}

The default inheritance type of a class in C++ is private, so any public and protected members from the base class are limited to private. struct inheritance on the other hand is public by default.

It's the special table in Oracle. I often use it for calculations or checking system variables. For example:

• Select 2*4 from dual prints out the result of the calculation
• Select sysdate from dual prints the server current date.

I think one error in the original code might have been that it had:

$message = echo getRequestURI();

instead of:

$message = getRequestURI();

(The code has since been edited though.)

Using jQuery:

$(document).ready(function() {
    $(".myElement").wrap( '<span class="myElement_container_new"></span>' ); // for IE6
    $(".myElement_container_new").css({// for IE6
        "display" : "block",
        "position" : "relative",
        "margin" : "0",
        "padding" : "0",
        "border" : "none",
        "background-color" : "transparent",
        "clear" : "both",
        "text-align" : "center"
    });
    $(".myElement").css({
        "display" : "block",
        "position" : "relative",
        "max-width" : "75%", // for example
        "margin-left" : "auto",
        "margin-right" : "auto",
        "clear" : "both",
        "text-align" : "left"
    });
});

or, if you want to center every element with class ".myElement":

$(document).ready(function() {
    $(".myElement").each(function() {
        $(this).wrap( '<span class="myElement_container_new"></span>' ); // for IE6
        $(".myElement_container_new").css({// for IE6
            "display" : "block",
            "position" : "relative",
            "margin" : "0",
            "padding" : "0",
            "border" : "none",
            "background-color" : "transparent",
            "clear" : "both",
            "text-align" : "center"
        });
        $(this).css({
            "display" : "block",
            "position" : "relative",
            "max-width" : "75%",
            "margin-left" : "auto",
            "margin-right" : "auto",
            "clear" : "both",
            "text-align" : "left"
        });
    });
});

cat can also be used following a | to write to a file, i.e. pipe feeds cat a stream of data

I made this short example which also works.

#include <iostream>
#include <type_traits>

class foo;
class bar;

template<class T>
struct is_bar
{
    template<class Q = T>
    typename std::enable_if<std::is_same<Q, bar>::value, bool>::type check()
    {
        return true;
    }

    template<class Q = T>
    typename std::enable_if<!std::is_same<Q, bar>::value, bool>::type check()
    {
        return false;
    }
};

int main()
{
    is_bar<foo> foo_is_bar;
    is_bar<bar> bar_is_bar;
    if (!foo_is_bar.check() && bar_is_bar.check())
        std::cout << "It works!" << std::endl;

    return 0;
}

Comment if you want me to elaborate. I think the code is more or less self-explanatory, but then again I made it so I might be wrong :)

You can see it in action here.

<div ng-app="" ng-controller="myCntrl">    
        <input type="radio" ng-model="people" value="1"/><label>1</label>
        <input type="radio" ng-model="people" value="2"/><label>2</label>
        <input type="radio" ng-model="people" value="3"/><label>3</label>
</div>
<script>
    function myCntrl($scope){
        $scope.people=1;
    }
</script>

A convoluted way is to create your own Runner by subclassing org.junit.runners.BlockJUnit4ClassRunner.

You can then do something like this:

public class NameAwareRunner extends BlockJUnit4ClassRunner {

    public NameAwareRunner(Class<?> aClass) throws InitializationError {
        super(aClass);
    }

    @Override
    protected Statement methodBlock(FrameworkMethod frameworkMethod) {
        System.err.println(frameworkMethod.getName());
        return super.methodBlock(frameworkMethod);
    }
}

Then for each test class, you'll need to add a @RunWith(NameAwareRunner.class) annotation. Alternatively, you could put that annotation on a Test superclass if you don't want to remember it every time. This, of course, limits your selection of runners but that may be acceptable.

Also, it may take a little bit of kung fu to get the current test name out of the Runner and into your framework, but this at least gets you the name.

Native way to get the mimetype:

For PHP < 5.3 use mime_content_type()
For PHP >= 5.3 use finfo_open() or mime_content_type()

Alternatives to get the MimeType are exif_imagetype and getimagesize, but these rely on having the appropriate libs installed. In addition, they will likely just return image mimetypes, instead of the whole list given in magic.mime.

While mime_content_type is available from PHP 4.3 and is part of the FileInfo extension (which is enabled by default since PHP 5.3, except for Windows platforms, where it must be enabled manually, for details see here).

If you don't want to bother about what is available on your system, just wrap all four functions into a proxy method that delegates the function call to whatever is available, e.g.

function getMimeType($filename)
{
    $mimetype = false;
    if(function_exists('finfo_open')) {
        // open with FileInfo
    } elseif(function_exists('getimagesize')) {
        // open with GD
    } elseif(function_exists('exif_imagetype')) {
       // open with EXIF
    } elseif(function_exists('mime_content_type')) {
       $mimetype = mime_content_type($filename);
    }
    return $mimetype;
}

I fixed this issue by deleting the output file and running the command again. It turns out it does NOT overwrite the previous file. I had this issue when renewing a let's encrypt cert with tomcat

Install this package in Ubuntu:

apt install sysv-rc-conf

its a substitute for chkconfig cmd.

After install run this cmd:

sysv-rc-conf --list

It'll show all services in all the runlevels. You can also run this:

sysv-rc-conf --level (runlevel number ex:1 2 3 4 5 6 )

Now you can choose which service should be active in boot time.

Above answers are correct. This version is easy to follow:

Because "Schema export directory is not provided to the annotation processor", So we need to provide the directory for schema export:

Step [1] In your file which extends the RoomDatabase, change the line to:

`@Database(entities = ???.class,version = 1, exportSchema = true)`

Or

`@Database(entities = ???.class,version = 1)` 

(because the default value is always true)

Step [2] In your build.gradle(project:????) file, inside the defaultConfig{ } (which is inside android{ } big section), add the javaCompileOptions{ } section, it will be like:

         android{
                defaultConfig{
                      //javaComplieOptions SECTION
                      javaCompileOptions {
                            annotationProcessorOptions {
                                     arguments = ["room.schemaLocation":"$projectDir/schemas".toString()]
                            }
                       }
                      //Other SECTION
                      ...
                }
         }

$projectDir:is a variable name, you cannot change it. it will get your own project directory

schemas:is a string, you can change it to any you like. For example: "$projectDir/MyOwnSchemas".toString()

This is perhaps the best explanations on why to use lambda expressions -> https://youtu.be/j9nj5dTo54Q

In summary, it's to improve code readability, reduce chances of errors by reusing rather than replicating code, and leverage optimization happening behind the scenes.

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

Cheers!!!

You could do it like this:

String s = "1234567890";
System.out.println(java.util.Arrays.toString(s.split("(?<=\\G...)")));

which produces:

[123, 456, 789, 0]

The regex (?<=\G...) matches an empty string that has the last match (\G) followed by three characters (...) before it ((?<= ))

A stateless system can be seen as a box [black? ;)] where at any point in time the value of the output(s) depends only on the value of the input(s) [after a certain processing time]

A stateful system instead can be seen as a box where at any point in time the value of the output(s) depends on the value of the input(s) and of an internal state, so basicaly a stateful system is like a state machine with "memory" as the same set of input(s) value can generate different output(s) depending on the previous input(s) received by the system.

From the parallel programming point of view, a stateless system, if properly implemented, can be executed by multiple threads/tasks at the same time without any concurrency issue [as an example think of a reentrant function] A stateful system will requires that multiple threads of execution access and update the internal state of the system in an exclusive way, hence there will be a need for a serialization [synchronization] point.

You can try something like this I guess:

new_str = ""
str_value = "rojbasr"
for i in str_value:
    new_str += "0x%s " % (i.encode('hex'))
print new_str

Your output would be something like this:

0x72 0x6f 0x6a 0x62 0x61 0x73 0x72

I would recommend using the execute method which returns null if no match exists otherwise it returns a helpful object.

let case1 = /^([a-z0-9]{5,})$/.exec("abc1");
console.log(case1); //null

let case2 = /^([a-z0-9]{5,})$/.exec("pass3434");
console.log(case2); // ['pass3434', 'pass3434', index:0, input:'pass3434', groups: undefined]

My problem was not resolved with this procedure

FirebaseApp.initializeApp(this);

        var obj = '<input id="list'+index+'" name=list['+index+']  class="required" />'
        $("#parent").append(obj);

        $("#list"+index).rules("add", "required");
        $("#index").val(index)
    }

This happened to me also, while i was reading text containing Hebrew from a .txt file.

dynamic_cast can determine if the type contains the target type anywhere in the inheritance hierarchy (yes, it's a little-known feature that if B inherits from A and C, it can turn an A* directly into a C*). typeid() can determine the exact type of the object. However, these should both be used extremely sparingly. As has been mentioned already, you should always be avoiding dynamic type identification, because it indicates a design flaw. (also, if you know the object is for sure of the target type, you can do a downcast with a static_cast. Boost offers a polymorphic_downcast that will do a downcast with dynamic_cast and assert in debug mode, and in release mode it will just use a static_cast).

vector<char> toVector( const std::string& s ) {
  string s = "apple";  
  vector<char> v(s.size()+1);
  memcpy( &v.front(), s.c_str(), s.size() + 1 );
  return v;
}
vector<char> v = toVector(std::string("apple"));

// what you were looking for (mutable)
char* c = v.data();

.c_str() works for immutable. The vector will manage the memory for you.

Parts of the GCC runtime (the exception handling, in particular) are dependent on the threading model being used. So, if you're using the version of the runtime that was built with POSIX threads, but decide to create threads in your own code with the Win32 APIs, you're likely to have problems at some point.

Even if you're using the Win32 threading version of the runtime you probably shouldn't be calling the Win32 APIs directly. Quoting from the MinGW FAQ:

As MinGW uses the standard Microsoft C runtime library which comes with Windows, you should be careful and use the correct function to generate a new thread. In particular, the CreateThread function will not setup the stack correctly for the C runtime library. You should use _beginthreadex instead, which is (almost) completely compatible with CreateThread.

UTF-16 Byte Array

JavaScript encodes strings as UTF-16, just like C#'s UnicodeEncoding, so the byte arrays should match exactly using charCodeAt(), and splitting each returned byte pair into 2 separate bytes, as in:

function strToUtf16Bytes(str) {
  const bytes = [];
  for (ii = 0; ii < str.length; ii++) {
    const code = str.charCodeAt(ii); // x00-xFFFF
    bytes.push(code & 255, code >> 8); // low, high
  }
  return bytes;
}

For example:

strToUtf16Bytes(''); 
// [ 60, 216, 53, 223 ]

However, If you want to get a UTF-8 byte array, you must transcode the bytes.

UTF-8 Byte Array

The solution feels somewhat non-trivial, but I used the code below in a high-traffic production environment with great success (original source).

Also, for the interested reader, I published my unicode helpers that help me work with string lengths reported by other languages such as PHP.

/**
 * Convert a string to a unicode byte array
 * @param {string} str
 * @return {Array} of bytes
 */
export function strToUtf8Bytes(str) {
  const utf8 = [];
  for (let ii = 0; ii < str.length; ii++) {
    let charCode = str.charCodeAt(ii);
    if (charCode < 0x80) utf8.push(charCode);
    else if (charCode < 0x800) {
      utf8.push(0xc0 | (charCode >> 6), 0x80 | (charCode & 0x3f));
    } else if (charCode < 0xd800 || charCode >= 0xe000) {
      utf8.push(0xe0 | (charCode >> 12), 0x80 | ((charCode >> 6) & 0x3f), 0x80 | (charCode & 0x3f));
    } else {
      ii++;
      // Surrogate pair:
      // UTF-16 encodes 0x10000-0x10FFFF by subtracting 0x10000 and
      // splitting the 20 bits of 0x0-0xFFFFF into two halves
      charCode = 0x10000 + (((charCode & 0x3ff) << 10) | (str.charCodeAt(ii) & 0x3ff));
      utf8.push(
        0xf0 | (charCode >> 18),
        0x80 | ((charCode >> 12) & 0x3f),
        0x80 | ((charCode >> 6) & 0x3f),
        0x80 | (charCode & 0x3f),
      );
    }
  }
  return utf8;
}

Below query will provide exactly the same result as given in the desired response:

db.books.aggregate([
    {
        $group: {
            _id: { addresses: "$addr", books: "$book" },
            num: { $sum :1 }
        }
    },
    {
        $group: {
            _id: "$_id.addresses",

You have a dash in the middle of the character class, which will mean a character range. Put the dash at the end of the class like so:

Peachpie

http://www.peachpie.io

https://github.com/iolevel/peachpie

Peachpie is PHP 7 compiler based on Roslyn by Microsoft and drawing from popular Phalanger. It allows PHP to be executed within the .NET/.NETCore by compiling the PHP code to pure MSIL.

Phalanger

http://v4.php-compiler.net/

http://wiki.php-compiler.net/Phalanger_Wiki

https://github.com/devsense/phalanger

Phalanger is a project which was started at Charles University in Prague and was supported by Microsoft. It compiles source code written in the PHP scripting language into CIL (Common Intermediate Language) byte-code. It handles the beginning of a compiling process which is completed by the JIT compiler component of the .NET Framework. It does not address native code generation nor optimization. Its purpose is to compile PHP scripts into .NET assemblies, logical units containing CIL code and meta-data.

Bambalam

https://github.com/xZero707/Bamcompile/

Bambalam PHP EXE Compiler/Embedder is a free command line tool to convert PHP applications to standalone Windows .exe applications. The exe files produced are totally standalone, no need for php dlls etc. The php code is encoded using the Turck MMCache Encode library so it's a perfect solution if you want to distribute your application while protecting your source code. The converter is also suitable for producing .exe files for windowed PHP applications (created using for example the WinBinder library). It's also good for making stand-alone PHP Socket servers/clients (using the php_sockets.dll extension). It's NOT really a compiler in the sense that it doesn't produce native machine code from PHP sources, but it works!

ZZEE PHPExe

http://www.zzee.com/phpexe/

ZZEE PHPExe compiles PHP, HTML, Javascript, Flash and other web files into Windows GUI exes. You can rapidly develop Windows GUI applications by employing the familiar PHP web paradigm. You can use the same code for online and Windows applications with little or no modification. It is a Commercial product.

phc-win

http://wiki.swiftlytilting.com/Phc-win

The PHP extension bcompiler is used to compile PHP script code into PHP bytecode. This bytecode can be included just like any php file as long as the bcompiler extension is loaded. Once all the bytecode files have been created, a modified Embeder is used to pack all of the project files into the program exe.

Requires

• php5ts.dll
• php_win32std.dll
• php_bcompiler.dll
• php-embed.ini

ExeOutput

http://www.exeoutput.com/

Commercial

WinBinder

http://winbinder.org/

WinBinder is an open source extension to PHP, the script programming language. It allows PHP programmers to easily build native Windows applications, producing quick and rewarding results with minimum effort. Even short scripts with a few dozen lines can generate a useful program, thanks to the power and flexibility of PHP.

PHPDesktop

https://github.com/cztomczak/phpdesktop

PHP Desktop is an open source project founded by Czarek Tomczak in 2012 to provide a way for developing native desktop applications using web technologies such as PHP, HTML5, JavaScript & SQLite. This project is more than just a PHP to EXE compiler, it embeds a web-browser (Internet Explorer or Chrome embedded), a Mongoose web-server and a PHP interpreter. The development workflow you are used to remains the same, the step of turning an existing website into a desktop application is basically a matter of copying it to "www/" directory. Using SQLite database is optional, you could embed mysql/postgresql database in application's installer.

PHP Nightrain

https://github.com/kjellberg/nightrain

Using PHP Nightrain you will be able to deploy and run HTML, CSS, JavaScript and PHP web applications as a native desktop application on Windows, Mac and the Linux operating systems. Popular PHP Frameworks (e.g. CakePHP, Laravel, Drupal, etc…) are well supported!

phc-win "fork"

https://github.com/RDashINC/phc-win

A more-or-less forked version of phc-win, it uses the same techniques as phc-win but supports almost all modern PHP versions. (5.3, 5.4, 5.5, 5.6, etc) It also can use Enigma VB to combine the php5ts.dll with your exe, aswell as UPX compress it. Lastly, it has win32std and winbinder compilied statically into PHP.

EDIT

Another option is to use

http://www.appcelerator.com/products/titanium-cross-platform-application-development/

an online compiler that can build executables for a number of different platforms, from a number of different languages including PHP

TideSDK

http://www.tidesdk.org/

TideSDK is actually the renamed Titanium Desktop project. Titanium remained focused on mobile, and abandoned the desktop version, which was taken over by some people who have open sourced it and dubbed it TideSDK.

Generally, TideSDK uses HTML, CSS and JS to render applications, but it supports scripted languages like PHP, as a plug-in module, as well as other scripting languages like Python and Ruby.

Note that there are two different types of equality in C#

1- Value Equality (For value types like int, DateTime and struct)

2- Reference Equality (For objects)

There are two basic standard protocols for implement equality checks.

1- The == and != operators.

2- The virtual Equals method.

The == and != are statically resolve, which means C# will make a compile-time decision as to which type will perform the comparison.

For instance the value-type

 int x = 50;
 int y = 50;
 Console.WriteLine (x == y); // True

but for reference type

 object x = 50;
 object y = 50;
 Console.WriteLine (x == y); // False 

The Equals() originally resoled at runtime according to operand actual type.

For instance, in the following example, at runtime, it will be decided that the Equals() will apply on int values, the result is true.

object x = 5;
object y = 5;
Console.WriteLine (x.Equals (y)); // True

However, for a reference type, it will use a reference equality check.

MyObject x = new MyObject();
MyObject y = x;
Console.WriteLine (x.Equals (y)); // True

Note that Equals() uses structural comparison for struct, which means it calls Equals on each field of a struct.

I got this error today because the "Source" is missing the ApacheJmeter.jar. I downloaded it again from "Binaries" and everything works as expected.

Update:

The plugin previously mentioned has been abandoned, but it apparently has an up-to-date fork here.

Old Answer:

I use the Android Studio plugin named Android Drawable Importer:

To use it after installed, right click your res/drawable folder and select New > Batch Drawable Import:

Then select your image via the + button and set the Resolution to be xxhdpi (or whatever the resolution of your source image is).

If lakes is your DataFrame, you can do something like

area_dict = dict(zip(lakes.area, lakes.count))

You should be able to do the count on the purch variable:

purch.Count();

e.g.

var purch = from purchase in myBlaContext.purchases
select purchase;

purch.Count();

Nginx prefers prefix-based location matches (not involving regular expression), that's why in your code block, /stash redirects are going to /.

The algorithm used by Nginx to select which location to use is described thoroughly here: https://www.digitalocean.com/community/tutorials/understanding-nginx-server-and-location-block-selection-algorithms#matching-location-blocks

I got this error and found that I don't have my SSH port (non standard number) whitelisted in config server firewall.

In addition to the other answers, Class defines the method === to test whether an object is an instance of that class.

• o.class class of o.
• o.instance_of? c determines whether o.class == c
• o.is_a? c Is o an instance of c or any of it's subclasses?
• o.kind_of? c synonym for *is_a?*
• c === o for a class or module, determine if *o.is_a? c* (String === "s" returns true)

Some practical uses for the [Serializable] attribute:

• Saving object state using binary serialisation; you can very easily 'save' entire object instances in your application to a file or network stream and then recreate them by deserialising - check out the BinaryFormatter class in System.Runtime.Serialization.Formatters.Binary
• Writing classes whose object instances can be stored on the clipboard using Clipboard.SetData() - nonserialisable classes cannot be placed on the clipboard.
• Writing classes which are compatible with .NET Remoting; generally, any class instance you pass between application domains (except those which extend from MarshalByRefObject) must be serialisable.

These are the most common usage cases that I have come across.

The easiest method to solve your problem (without going to a different editor or learning regex) is to record a macro.

• Place your cursor at the start of your text, click the 'record' button in the ribbon, and then edit just that one row of text. You may only use arrow keys or ctrl+arrow keys to move around characters/words rather than clicking with your mouse. The 'home' and 'end' keys are also useful.
• When you're finished with that one line, move your cursor (again without using the mouse) to the start of the next line.
• Click the 'stop recording' button.
• Click the 'play macro' button to check that it works on the next line as expected.
• Click the 'run macro multiple times' to do it again, and again, and again... :P

I think the best solution is converting each char to HEX and replace it with another HEX. It's because there are 2 Unicode typing:

Composite Unicode
Precomposed Unicode

For example "Ô`" written by Composite Unicode is different from "?" written by Precomposed Unicode. You can copy my sample chars and convert them to see the difference.

In Composite Unicode, "Ô`" is combined from 2 char: Ô (U+00d4) and ` (U+0300)
In Precomposed Unicode, "?" is single char (U+1ED2)

I have developed this feature for some banks to convert the info before sending it to core-bank (usually don't support Unicode) and faced this issue when the end-users use multiple Unicode typing to input the data. So I think, converting to HEX and replace it is the most reliable way.

UPDATE: The stroke-alignment attribute was on April 1st, 2015 moved to a completely new spec called SVG Strokes.

As of the SVG 2.0 Editor’s Draft of February 26th, 2015 (and possibly since February 13th), the stroke-alignment property is present with the values inner, center (default) and outer.

It seems to work the same way as the stroke-location property proposed by @Phrogz and the later stroke-position suggestion. This property has been planned since at least 2011, but apart from an annotation that said

SVG 2 shall include a way to specify stroke position

, it has never been detailed in the spec as it was deferred - until now, it seems.

No browser support this property, or, as far as I know, any of the new SVG 2 features, yet, but hopefully they will soon as the spec matures. This has been a property I personally have been urging to have, and I'm really happy that it's finally there in the spec.

There seems to be some issues as to how to the property should behave on open paths as well as loops. These issues will, most probably, prolong implementations across browsers. However, I will update this answer with new information as browsers begin to support this property.

It's the "frame" or "range" clause of window functions, which are part of the SQL standard and implemented in many databases, including Teradata.

A simple example would be to calculate the average amount in a frame of three days. I'm using PostgreSQL syntax for the example, but it will be the same for Teradata:

WITH data (t, a) AS (
  VALUES(1, 1),
        (2, 5),
        (3, 3),
        (4, 5),
        (5, 4),
        (6, 11)
)
SELECT t, a, avg(a) OVER (ORDER BY t ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING)
FROM data
ORDER BY t

... which yields:

t  a  avg
----------
1  1  3.00
2  5  3.00
3  3  4.33
4  5  4.00
5  4  6.67
6 11  7.50

As you can see, each average is calculated "over" an ordered frame consisting of the range between the previous row (1 preceding) and the subsequent row (1 following).

When you write ROWS UNBOUNDED PRECEDING, then the frame's lower bound is simply infinite. This is useful when calculating sums (i.e. "running totals"), for instance:

WITH data (t, a) AS (
  VALUES(1, 1),
        (2, 5),
        (3, 3),
        (4, 5),
        (5, 4),
        (6, 11)
)
SELECT t, a, sum(a) OVER (ORDER BY t ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW)
FROM data
ORDER BY t

yielding...

t  a  sum
---------
1  1    1
2  5    6
3  3    9
4  5   14
5  4   18
6 11   29

Here's another very good explanations of SQL window functions.

1. For arrays of limited length use the following (as given by camickr). This is slow for repeated checks, especially for longer arrays (linear search).

    Arrays.asList(...).contains(...)
   

2. For fast performance if you repeatedly check against a larger set of elements

   • An array is the wrong structure. Use a TreeSet and add each element to it. It sorts elements and has a fast exist() method (binary search).

   • If the elements implement Comparable & you want the TreeSet sorted accordingly:

     ElementClass.compareTo() method must be compatable with ElementClass.equals(): see Triads not showing up to fight? (Java Set missing an item)

     TreeSet myElements = new TreeSet();
     
     // Do this for each element (implementing *Comparable*)
     myElements.add(nextElement);
     
     // *Alternatively*, if an array is forceably provided from other code:
     myElements.addAll(Arrays.asList(myArray));
     

   • Otherwise, use your own Comparator:

     class MyComparator implements Comparator<ElementClass> {
          int compareTo(ElementClass element1; ElementClass element2) {
               // Your comparison of elements
               // Should be consistent with object equality
          }
     
          boolean equals(Object otherComparator) {
               // Your equality of comparators
          }
     }
     
     
     // construct TreeSet with the comparator
     TreeSet myElements = new TreeSet(new MyComparator());
     
     // Do this for each element (implementing *Comparable*)
     myElements.add(nextElement);
     

   • The payoff: check existence of some element:

     // Fast binary search through sorted elements (performance ~ log(size)):
     boolean containsElement = myElements.exists(someElement);
     

If you are having similar issues with pure components or classes, ensure you are using .js extension instead of .jsx.

If I were explaining this to someone I'd say we'll get to it later for now you need to know that the way to run your program is to use :

public static void main(String[] args) {
        ...
    }

Assuming he/she knows what an array is, I'd say the args is an argument array and you can show some cool examples.

Then after you've gone a bit about Java/JVM and that stuff, you'd get to modifiers eventually to static and public as well.

Then you can spend some time talking about meaning of these IMHO.

You could mention other "cool" stuff such as varargs that you can use this in later versions of Java.

public static void main(String ...args) {
        //...
    }

I can see that this question was originally posted 5 yrs ago when programmers had to work harder to get their desired results. With Visual Studio 2012 and beyond, a lazy programmer can go the Design View for the Listview properties settings, and click on Properties->Sorting, choose Ascending. There are plenty of other properties features to obtain the various results a lazy (aka smart) programmer can leverage.

you can use raiserror. Read more details here

--from MSDN

BEGIN TRY
    -- RAISERROR with severity 11-19 will cause execution to 
    -- jump to the CATCH block.
    RAISERROR ('Error raised in TRY block.', -- Message text.
               16, -- Severity.
               1 -- State.
               );
END TRY
BEGIN CATCH
    DECLARE @ErrorMessage NVARCHAR(4000);
    DECLARE @ErrorSeverity INT;
    DECLARE @ErrorState INT;

    SELECT 
        @ErrorMessage = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState = ERROR_STATE();

    -- Use RAISERROR inside the CATCH block to return error
    -- information about the original error that caused
    -- execution to jump to the CATCH block.
    RAISERROR (@ErrorMessage, -- Message text.
               @ErrorSeverity, -- Severity.
               @ErrorState -- State.
               );
END CATCH;

EDIT If you are using SQL Server 2012+ you can use throw clause. Here are the details.

If you are Using HTML5 you can add the attribute 'download' to your links.

<a href="/test.pdf" download>

http://www.w3schools.com/tags/att_a_download.asp

As noted by @mastablasta, but also to add that if you call the 'done' argument or rather name it completed you just call the callback completed() in your test when it's done.

// this block signature will trigger async behavior.
it("should work", function(done){
  // do stuff and then call done...
  done();
});

// this block signature will run synchronously
it("should work", function(){
  //...
});

You can get another validation on this tutorial : http://twitterbootstrap.org/bootstrap-form-validation

They use JQuery validation.

jquery.validate.js

jquery.validate.min.js

jquery-1.7.1.min.js

And you'll get the source code there.

happy coding.

Use a CultureInfo like this, from MSDN:

// Creates a CultureInfo for German in Germany.
CultureInfo ci = new CultureInfo("de-DE");

// Displays dt, formatted using the CultureInfo
Console.WriteLine(dt.ToString(ci));

More info on MSDN. Here is a link of all different cultures.

https://lodash.com/docs#isEmpty comes in pretty handy:

_.isEmpty({})   // true
_.isEmpty()     // true
_.isEmpty(null) // true
_.isEmpty("")   // true

You can use find_all in the following way to find every a element that has an href attribute, and print each one:

from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']

The output would be:

Found the URL: some_url
Found the URL: another_url

Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all instead.

If you want all tags with an href, you can omit the name parameter:

href_tags = soup.find_all(href=True)

You could do something like this in a loop based on the number of text fields they enter.

$('<input/>').attr({type:'text',name:'text'+i}).appendTo('#myform');

But for better performance I'd create all the html first and inject it into the DOM only once.

var count = 20;
var html = [];
while(count--) {
  html.push("<input type='text' name='name", count, "'>");
}
$('#myform').append(html.join(''));

Edit this example uses jQuery to append the html, but you could easily modify it to use innerHTML as well.

If you want to avoid the hassle of escaping the special characters in your search and replacement string when using regular expressions, do the following steps:

1. Search for your original string, and replace it with "UniqueString42", with regular expressions off.
2. Search for "UniqueString42" and replace it with "UniqueString42\nUniqueString1337", with regular expressions on
3. Search for "UniqueString42" and replace it with the first line of your replacement (often your original string), with regular expressions off.
4. Search for "UniqueString42" and replace it with the second line of your replacement, with regular expressions off.

Note that even if you want to manually pich matches for the first search and replace, you can safely use "replace all" for the three last steps.

Example

For example, if you want to replace this:

public IFoo SomeField { get { return this.SomeField; } }

with that:

public IFoo Foo { get { return this.MyFoo; } }
public IBar Bar { get { return this.MyBar; } }

You would do the following substitutions:

1. public IFoo SomeField { get { return this.SomeField; } } ? XOXOXOXO (regex off).
2. XOXOXOXO ? XOXOXOXO\nHUHUHUHU (regex on).
3. XOXOXOXO ? public IFoo Foo { get { return this.MyFoo; } } (regex off).
4. HUHUHUHU ? public IFoo Bar { get { return this.MyBar; } } (regex off).

If you use native sql, you can refer to my code, otherwise just ignore my answer.

SELECT * FROM table WHERE tags LIKE "%banana%";

from sqlalchemy import text

bar_tags = "banana"

# '%' attention to spaces
query_sql = """SELECT * FROM table WHERE tags LIKE '%' :bar_tags '%'"""

# db is sqlalchemy session object
tags_res_list = db.execute(text(query_sql), {"bar_tags": bar_tags}).fetchall()

Could not commit JPA transaction: Transaction marked as rollbackOnly

This exception occurs when you invoke nested methods/services also marked as @Transactional. JB Nizet explained the mechanism in detail. I'd like to add some scenarios when it happens as well as some ways to avoid it.

Suppose we have two Spring services: Service1 and Service2. From our program we call Service1.method1() which in turn calls Service2.method2():

class Service1 {
    @Transactional
    public void method1() {
        try {
            ...
            service2.method2();
            ...
        } catch (Exception e) {
            ...
        }
    }
}

class Service2 {
    @Transactional
    public void method2() {
        ...
        throw new SomeException();
        ...
    }
}

SomeException is unchecked (extends RuntimeException) unless stated otherwise.

Scenarios:

1. Transaction marked for rollback by exception thrown out of method2. This is our default case explained by JB Nizet.

2. Annotating method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

3. Annotating both method1 and method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

4. Annotating method2 with @Transactional(noRollbackFor = SomeException) prevents marking transaction for rollback (no exception thrown when exiting from method1).

5. Suppose method2 belongs to Service1. Invoking it from method1 does not go through Spring's proxy, i.e. Spring is unaware of SomeException thrown out of method2. Transaction is not marked for rollback in this case.

6. Suppose method2 is not annotated with @Transactional. Invoking it from method1 does go through Spring's proxy, but Spring pays no attention to exceptions thrown. Transaction is not marked for rollback in this case.

7. Annotating method2 with @Transactional(propagation = Propagation.REQUIRES_NEW) makes method2 start new transaction. That second transaction is marked for rollback upon exit from method2 but original transaction is unaffected in this case (no exception thrown when exiting from method1).

8. In case SomeException is checked (does not extend RuntimeException), Spring by default does not mark transaction for rollback when intercepting checked exceptions (no exception thrown when exiting from method1).

See all scenarios tested in this gist.

I can't comment on the above answer, but be careful with @Pavel Chuchuva's answer. That formula will not return a result if both coordinates are the same. In that case, distance is null, and so that row won't be returned with that formula as is.

I'm not a MySQL expert, but this seems to be working for me:

SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * sin( radians( lat ) ) ) ) AS distance 
FROM markers HAVING distance < 25 OR distance IS NULL ORDER BY distance LIMIT 0 , 20;

Based on acheron55 answer I posted a possible implementation here.
Here is a brief summery of it:

All you have to do, is to keep track of the path through which the target has been reached. A simple way to do it, is to push into the Queue the whole path used to reach a node, rather than the node itself.
The benefit of doing so is that when the target has been reached the queue holds the path used to reach it.
This is also applicable to cyclic graphs, where a node can have more than one parent.

If using in fragment then simply write

getActivity().runOnUiThread(new Runnable() {
    @Override
    public void run() {
        // Do something on UiThread
    }
});

CREATE TABLE dbo.OwnerType
(
    ID int NOT NULL,
    Name varchar(50) NULL
)

insert into OwnerType (Name) values ('User');
insert into OwnerType (Name) values ('Group');

I think that would be the most general way to represent what you want instead of using a flag.

This issue can occur if the Azure Active Directory Module for Windows PowerShell isn't loaded correctly.

To resolve this issue, follow these steps.
1.Install the Azure Active Directory Module for Windows PowerShell on the computer (if it isn't already installed). To install the Azure Active Directory Module for Windows PowerShell, go to the following Microsoft website:
Manage Azure AD using Windows PowerShell

2.If the MSOnline module isn't present, use Windows PowerShell to import the MSOnline module.

Import-Module MSOnline 

After it complete, we can use this command to check it.

PS C:\Users> Get-Module -ListAvailable -Name MSOnline*


    Directory: C:\windows\system32\WindowsPowerShell\v1.0\Modules

Update:

We should import azure AD powershell to VS 2015, we can add tool and select Azure AD powershell.

The current HTML5 draft specification does not specify which video formats browsers should support in the video tag. User agents are free to support any video formats they feel are appropriate.

The URI to open a specific channel in Slack app is:

slack://channel?id=<CHANNEL-ID>&team=<TEAM-ID>

You will probably need these resources of the Slack API to get IDs of your team and channel:

• GET https://slack.com/api/team.info
• GET https://slack.com/api/channels.list?exclude_archived=1

Here's the full documentation from Slack

You could do:

svn revert -R .

This will not delete any new file not under version control. But you can easily write a shell script to do that like:

for file in `svn status|grep "^ *?"|sed -e 's/^ *? *//'`; do rm $file ; done

I had a similar problem using Flask, but I did not have to resort to JSON. I just passed a list letters = ['a','b','c'] with render_template('show_entries.html', letters=letters), and set

var letters = {{ letters|safe }}

in my javascript code. Jinja2 replaced {{ letters }} with ['a','b','c'], which javascript interpreted as an array of strings.

You can't really, but you a halfway step might be:

<input type='number' step='0.01' value='0.00' placeholder='0.00' />

For Windows Server® 2008, Windows 7, Windows Server 2003, Windows Vista®, or Windows XP run "control userpasswords2"

• Click the Start button, then click Run (Windows XP, Server 2003 or below)

• Type control userpasswords2 and press Enter on your keyboard.

Note: For Windows 7 and Windows Vista, this command will not run by typing it in the Serach box on the Start Menu - it must be run using the Run option. To add the Run command to your Start menu, right-click on it and choose the option to customize it, then go to the Advanced options. Check to option to add the Run command.

You will see a window of user details!

Another option is also using:

div
{
   white-space: pre-line;
}

This will set all your div elements in all browsers that support CSS1 (which is pretty much all common browsers as far back as IE 8)

We developed a page where it loaded a number of images and then performed other functions only after the image was loaded. It was a busy site that generated a lot of traffic. It seems that the following simple script worked on practically all browsers:

$(elem).onload = function() {
    doSomething();
}

BUT THIS IS A POTENTIAL ISSUE FOR IE9!

The ONLY browser we had reported issues on is IE9. Are we not surprised? It seems that the best way to solve the issue there is to not assign a src to the image until AFTER the onload function has been defined, like so:

$(elem).onload = function() {
    doSomething();
}
$(elem).attr('src','theimage.png');

It seems that IE 9 will sometimes not throw the onload event for whatever reason. Other solutions on this page (such as the one from Evan Carroll, for example) still did not work. Logically, that checked if the load state was already successful and triggered the function and if it wasn't, then set the onload handler, but even when you do that we demonstrated in testing that the image could load between those two lines of js thereby appearing not loaded to the first line and then loading before the onload handler is set.

We found that the best way to get what you want is to not define the image's src until you have set the onload event trigger.

We only just recently stopped supporting IE8 so I can't speak for versions prior to IE9, otherwise, out of all the other browsers that were used on the site -- IE10 and 11 as well as Firefox, Chrome, Opera, Safari and whatever mobile browser people were using -- setting the src before assigning the onload handler was not even an issue.

I think you missed a equal sign at:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);  

Change to:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null); 

2 steps to check if a cronjob is working :

1. Login on the server with the user that execute the cronjob

2. Manually run php command :

   /usr/bin/php /mydomain.in/cromail.php

And check if any error is displayed

I had this problem today using any of concat, append or merge, and I got around it by adding a helper column sequentially numbered and then doing an outer join

helper=1
for i in df1.index:
    df1.loc[i,'helper']=helper
    helper=helper+1
for i in df2.index:
    df2.loc[i,'helper']=helper
    helper=helper+1
df1.merge(df2,on='helper',how='outer')

_{Note: The question is about JavaScript, and this answer is about jQuery, which is wrong. This is an old answer, from times when jQuery was widespread.}

Instead, I recommend understanding scopes and closures in JavaScript.

Old, bad answer

With jQuery you can just do this, no matter where the declaration is:

$my_global_var = 'my value';

And will be available everywhere.

I use it for making quick image galleries, when images are spread in different places, like so:

$gallery = $('img');
$current = 0;

$gallery.each(function(i,v){
    // preload images
    (new Image()).src = v;
});
$('div').eq(0).append('<a style="display:inline-block" class="prev">prev</a> <div id="gallery"></div> <a style="display:inline-block" class="next">next</a>');
$('.next').click(function(){
    $current = ( $current == $gallery.length - 1 ) ? 0 : $current + 1;
    $('#gallery').hide().html($gallery[$current]).fadeIn();
});
$('.prev').click(function(){
    $current = ( $current == 0 ) ? $gallery.length - 1 : $current - 1;
    $('#gallery').hide().html($gallery[$current]).fadeIn();
});

Tip: run this whole code in the console in this page ;-)

The category workaround posted by Nathan de Vries will pass the AppStore private API checks, and is useful in cases where you do not have control of the NSUrlConnection object. One example is NSXMLParser which will open the URL you supply, but does not expose the NSURLRequest or NSURLConnection.

In iOS 4 the workaround still seems to work, but only on the device, the Simulator does not invoke the allowsAnyHTTPSCertificateForHost: method anymore.

As others have stated it's combination of your schema and the number of indexes.

A friend had about 100,000,000 historical stock prices, daily closing quotes, in an MDB which approached the 2 Gb limit.

He pulled them down using some code found in a Microsoft Knowledge base article. I was rather surprised that whatever server he was using didn't cut him off after the first 100K records.

He could view any record in under a second.

Since you're returning a string as JSON, that string will include the opening and closing quotes in the raw response. So your response should probably look like:

"abc123XYZ=="

or whatever...You can try confirming this with Fiddler.

My guess is that the result.Content is the raw string, including the quotes. If that's the case, then result.Content will need to be deserialized before you can use it.

An alternative stacking arrangement which works and is perhaps a bit more intuitive is the following:

struct ContentView: View {
    var body: some View {
        HStack() {
            VStack(alignment: .leading) {
                Text("Hello World")
                    .font(.title)
                Text("Another")
                    .font(.body)
                Spacer()
            }
            Spacer()
        }.background(Color.red)
    }
}

The content can also easily be re-positioned by removing the Spacer()'s if necessary.

STEP 1: Go to Firebase Console

STEP 2: Select your Project

STEP 3: Click on Settings icon and select Project Settings

STEP 4: Select CLOUD MESSAGING tab

The fix is that yes, vertical padding and margin are relative to width, but top and bottom aren't.

So just place a div inside another, and in the inner div, use something like top:50% (remember position matters if it still doesn't work)

I will try to cover it with examples:

Lock: One example where you would use lock would be a shared dictionary into which items (that must have unique keys) are added.
The lock would ensure that one thread does not enter the mechanism of code that is checking for item being in dictionary while another thread (that is in the critical section) already has passed this check and is adding the item. If another thread tries to enter a locked code, it will wait (be blocked) until the object is released.

private static readonly Object obj = new Object();

lock (obj) //after object is locked no thread can come in and insert item into dictionary on a different thread right before other thread passed the check...
{
    if (!sharedDict.ContainsKey(key))
    {
        sharedDict.Add(item);
    }
}

Semaphore: Let's say you have a pool of connections, then an single thread might reserve one element in the pool by waiting for the semaphore to get a connection. It then uses the connection and when work is done releases the connection by releasing the semaphore.

Code example that I love is one of bouncer given by @Patric - here it goes:

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

namespace TheNightclub
{
    public class Program
    {
        public static Semaphore Bouncer { get; set; }

        public static void Main(string[] args)
        {
            // Create the semaphore with 3 slots, where 3 are available.
            Bouncer = new Semaphore(3, 3);

            // Open the nightclub.
            OpenNightclub();
        }

        public static void OpenNightclub()
        {
            for (int i = 1; i <= 50; i++)
            {
                // Let each guest enter on an own thread.
                Thread thread = new Thread(new ParameterizedThreadStart(Guest));
                thread.Start(i);
            }
        }

        public static void Guest(object args)
        {
            // Wait to enter the nightclub (a semaphore to be released).
            Console.WriteLine("Guest {0} is waiting to entering nightclub.", args);
            Bouncer.WaitOne();          

            // Do some dancing.
            Console.WriteLine("Guest {0} is doing some dancing.", args);
            Thread.Sleep(500);

            // Let one guest out (release one semaphore).
            Console.WriteLine("Guest {0} is leaving the nightclub.", args);
            Bouncer.Release(1);
        }
    }
}

Mutex It is pretty much Semaphore(1,1) and often used globally (application wide otherwise arguably lock is more appropriate). One would use global Mutex when deleting node from a globally accessible list (last thing you want another thread to do something while you are deleting the node). When you acquire Mutex if different thread tries to acquire the same Mutex it will be put to sleep till SAME thread that acquired the Mutex releases it.

Good example on creating global mutex is by @deepee

class SingleGlobalInstance : IDisposable
{
    public bool hasHandle = false;
    Mutex mutex;

    private void InitMutex()
    {
        string appGuid = ((GuidAttribute)Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(GuidAttribute), false).GetValue(0)).Value.ToString();
        string mutexId = string.Format("Global\\{{{0}}}", appGuid);
        mutex = new Mutex(false, mutexId);

        var allowEveryoneRule = new MutexAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), MutexRights.FullControl, AccessControlType.Allow);
        var securitySettings = new MutexSecurity();
        securitySettings.AddAccessRule(allowEveryoneRule);
        mutex.SetAccessControl(securitySettings);
    }

    public SingleGlobalInstance(int timeOut)
    {
        InitMutex();
        try
        {
            if(timeOut < 0)
                hasHandle = mutex.WaitOne(Timeout.Infinite, false);
            else
                hasHandle = mutex.WaitOne(timeOut, false);

            if (hasHandle == false)
                throw new TimeoutException("Timeout waiting for exclusive access on SingleInstance");
        }
        catch (AbandonedMutexException)
        {
            hasHandle = true;
        }
    }


    public void Dispose()
    {
        if (mutex != null)
        {
            if (hasHandle)
                mutex.ReleaseMutex();
            mutex.Dispose();
        }
    }
}

then use like:

using (new SingleGlobalInstance(1000)) //1000ms timeout on global lock
{
    //Only 1 of these runs at a time
    GlobalNodeList.Remove(node)
}

Hope this saves you some time.

To check the emptiness of a queryset:

if orgs.exists():
    # Do something

or you can check for a the first item in a queryset, if it doesn't exist it will return None:

if orgs.first():
    # Do something

If you have a form action and an input type="submit" inside form tags, it's going to submit the old fashioned way and basically refresh the page. When doing AJAX type transactions this isn't the desired effect you are after.

Remove the action. Or remove the form altogether, though in cases it does come in handy to serialize to cut your workload. If the form tags remain, move the button outside the form tags, or alternatively make it a link with an onclick or click handler as opposed to an input button. Jquery UI Buttons works great in this case because you can mimic an input button with an a tag element.

Here's another option that's longer but may be more readable:

Boolean(Number("0")); // false
Boolean(Number("1")); // true

Unfortunately, the old xkcd comic isn't completely up to date anymore.

Since Python 3.0 you have to write:

print("Hello, World!")

And someone has still to write that antigravity library :(

There is no API for this, and you can't auto install it, you can just redirect them to it's Market page so they can upgrade. You can have your latest version in a file on a Web server, and have the app check it. Here's one implementation of this:

http://code.google.com/p/openintents/source/browse/#svn%2Ftrunk%2FUpdateCheckerApp

Your configuration should look similar to that. You may have to change <transport clientCredentialType="None" proxyCredentialType="None" /> depending on your needs for authentication. The config below doesn't require any authentication.

<bindings>
    <basicHttpBinding>
        <binding name="basicHttpBindingConfiguration">
            <security mode="Transport">
                <transport clientCredentialType="None" proxyCredentialType="None" />
            </security>
        </binding>       
    </basicHttpBinding>
</bindings>

<services>
    <service name="XXX">
        <endpoint
            name="AAA"
            address=""
            binding="basicHttpBinding"
            bindingConfiguration="basicHttpBindingConfiguration"
            contract="YourContract" />
    </service>
<services>

That will allow a WCF service with basicHttpBinding to use HTTPS.

If you're on a Unix-like system, use gettimeofday and convert the result from microseconds to milliseconds.

Popen.communicate() documentation:

Note that if you want to send data to the process’s stdin, you need to create the Popen object with stdin=PIPE. Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.

Replacing os.popen*

    pipe = os.popen(cmd, 'w', bufsize)
    # ==>
    pipe = Popen(cmd, shell=True, bufsize=bufsize, stdin=PIPE).stdin

Warning Use communicate() rather than stdin.write(), stdout.read() or stderr.read() to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process.

So your example could be written as follows:

from subprocess import Popen, PIPE, STDOUT

p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=STDOUT)    
grep_stdout = p.communicate(input=b'one\ntwo\nthree\nfour\nfive\nsix\n')[0]
print(grep_stdout.decode())
# -> four
# -> five
# ->

On Python 3.5+ (3.6+ for encoding), you could use subprocess.run, to pass input as a string to an external command and get its exit status, and its output as a string back in one call:

#!/usr/bin/env python3
from subprocess import run, PIPE

p = run(['grep', 'f'], stdout=PIPE,
        input='one\ntwo\nthree\nfour\nfive\nsix\n', encoding='ascii')
print(p.returncode)
# -> 0
print(p.stdout)
# -> four
# -> five
# -> 

Given this binary tree:

Breadth First Traversal:
Traverse across each level from left to right.

"I'm G, my kids are D and I, my grandkids are B, E, H and K, their grandkids are A, C, F"

- Level 1: G 
- Level 2: D, I 
- Level 3: B, E, H, K 
- Level 4: A, C, F

Order Searched: G, D, I, B, E, H, K, A, C, F

Depth First Traversal:
Traversal is not done ACROSS entire levels at a time. Instead, traversal dives into the DEPTH (from root to leaf) of the tree first. However, it's a bit more complex than simply up and down.

There are three methods:

1) PREORDER: ROOT, LEFT, RIGHT.
You need to think of this as a recursive process:  
Grab the Root. (G)  
Then Check the Left. (It's a tree)  
Grab the Root of the Left. (D)  
Then Check the Left of D. (It's a tree)  
Grab the Root of the Left (B)  
Then Check the Left of B. (A)  
Check the Right of B. (C, and it's a leaf node. Finish B tree. Continue D tree)  
Check the Right of D. (It's a tree)  
Grab the Root. (E)  
Check the Left of E. (Nothing)  
Check the Right of E. (F, Finish D Tree. Move back to G Tree)  
Check the Right of G. (It's a tree)  
Grab the Root of I Tree. (I)  
Check the Left. (H, it's a leaf.)  
Check the Right. (K, it's a leaf. Finish G tree)  
DONE: G, D, B, A, C, E, F, I, H, K  

2) INORDER: LEFT, ROOT, RIGHT
Where the root is "in" or between the left and right child node.  
Check the Left of the G Tree. (It's a D Tree)  
Check the Left of the D Tree. (It's a B Tree)  
Check the Left of the B Tree. (A)  
Check the Root of the B Tree (B)  
Check the Right of the B Tree (C, finished B Tree!)  
Check the Right of the D Tree (It's a E Tree)  
Check the Left of the E Tree. (Nothing)  
Check the Right of the E Tree. (F, it's a leaf. Finish E Tree. Finish D Tree)...  
Onwards until...   
DONE: A, B, C, D, E, F, G, H, I, K  

3) POSTORDER: 
LEFT, RIGHT, ROOT  
DONE: A, C, B, F, E, D, H, K, I, G

Usage (aka, why do we care):
I really enjoyed this simple Quora explanation of the Depth First Traversal methods and how they are commonly used:
"In-Order Traversal will print values [in order for the BST (binary search tree)]"
"Pre-order traversal is used to create a copy of the [binary search tree]."
"Postorder traversal is used to delete the [binary search tree]."

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

How it looks:

Best solution to my case. I need video fit web view size. Use embed youtube link with your video id. Example:

WebView youtubeWebView; //todo find or bind web view
String myVideoYoutubeId = "-bvXmLR3Ozc";

outubeWebView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
            }
        });

WebSettings webSettings = youtubeWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setUseWideViewPort(true);

youtubeWebView.loadUrl("https://www.youtube.com/embed/" + myVideoYoutubeId);

Web view xml code

<WebView
        android:id="@+id/youtube_web_view"
        android:layout_width="match_parent"
        android:layout_height="200dp"/>

Simply add height: 100%; onto the #B2 styling. min-height shouldn't be necessary.

If you:

• Don't want to load the whole file into a byte[] before sending to the response;
• Want/need to send/download it via InputStream;
• Want to have full control of the Mime Type and file name sent;
• Have other @ControllerAdvice picking up exceptions for you (or not).

The code below is what you need:

@RequestMapping(value = "/stuff/{stuffId}", method = RequestMethod.GET)
public ResponseEntity<FileSystemResource> downloadStuff(@PathVariable int stuffId)
                                                                      throws IOException {
    String fullPath = stuffService.figureOutFileNameFor(stuffId);
    File file = new File(fullPath);
    long fileLength = file.length(); // this is ok, but see note below

    HttpHeaders respHeaders = new HttpHeaders();
    respHeaders.setContentType("application/pdf");
    respHeaders.setContentLength(fileLength);
    respHeaders.setContentDispositionFormData("attachment", "fileNameIwant.pdf");

    return new ResponseEntity<FileSystemResource>(
        new FileSystemResource(file), respHeaders, HttpStatus.OK
    );
}

More on setContentLength(): First of all, the content-length header is optional per the HTTP 1.1 RFC. Still, if you can provide a value, it is better. To obtain such value, know that File#length() should be good enough in the general case, so it is a safe default choice.
In very specific scenarios, though, it can be slow, in which case you should have it stored previously (e.g. in the DB), not calculated on the fly. Slow scenarios include: if the file is very large, specially if it is on a remote system or something more elaborated like that - a database, maybe.

InputStreamResource

If your resource is not a file, e.g. you pick the data up from the DB, you should use InputStreamResource. Example:

    InputStreamResource isr = new InputStreamResource(new FileInputStream(file));
    return new ResponseEntity<InputStreamResource>(isr, respHeaders, HttpStatus.OK);

According to python documentation here is a statement:

8.15. types — Names for built-in types

Starting in Python 2.2, built-in factory functions such as int() and str() are also names for the corresponding types.

So isinstance() should be preferred over type().

If you are familiar with RxJava, you can use Observable.interval(), which is pretty neat.

Observable.interval(60, TimeUnits.SECONDS)
          .flatMap(new Function<Long, ObservableSource<String>>() {
                @Override
                public ObservableSource<String> apply(@NonNull Long aLong) throws Exception {
                    return getDataObservable(); //Where you pull your data
                }
            });

The downside of this is that you have to architect polling your data in a different way. However, there are a lot of benefits to the Reactive Programming way:

1. Instead of controlling your data via a callback, you create a stream of data that you subscribe to. This separates the concern of "polling data" logic and "populating UI with your data" logic so that you do not mix your "data source" code and your UI code.

2. With RxAndroid, you can handle threads in just 2 lines of code.

   Observable.interval(60, TimeUnits.SECONDS)
         .flatMap(...) // polling data code
         .subscribeOn(Schedulers.newThread()) // poll data on a background thread
         .observeOn(AndroidSchedulers.mainThread()) // populate UI on main thread
         .subscribe(...); // your UI code
   

Please check out RxJava. It has a high learning curve but it will make handling asynchronous calls in Android so much easier and cleaner.

Use this:

while IFS= read -r file ; do rm -- "$file" ; done < delete.list

If you need glob expansion you can omit quoting $file:

IFS=""
while read -r file ; do rm -- $file ; done < delete.list

But be warned that file names can contain "problematic" content and I would use the unquoted version. Imagine this pattern in the file

*
*/*
*/*/*

This would delete quite a lot from the current directory! I would encourage you to prepare the delete list in a way that glob patterns aren't required anymore, and then use quoting like in my first example.

app.all('*', function(req, res,next) {
    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});

You can use a function like this. Complete and modify it to your need :

/**
     * Encode URL (except :, /, ?, &, =, ... characters)
     * @param url to encode
     * @param encodingCharset url encoding charset
     * @return encoded URL
     * @throws UnsupportedEncodingException
     */
    public static String encodeUrl (String url, String encodingCharset) throws UnsupportedEncodingException{
            return new URLCodec().encode(url, encodingCharset).replace("%3A", ":").replace("%2F", "/").replace("%3F", "?").replace("%3D", "=").replace("%26", "&");
    }

Example of use :

String urlToEncode = ""http://www.growup.com/folder/intérieur-à_vendre?o=4";
Utils.encodeUrl (urlToEncode , "UTF-8")

The result is : http://www.growup.com/folder/int%C3%A9rieur-%C3%A0_vendre?o=4

If you know the location of installed jboss folder then simply open it and look for version.txt file.

For anyone else who runs into this...

Version 1.2.0 of this plugin (current as of this post) doesn't quite work in all cases as documented with Bootstrap 3.0, but it does with a minor workaround.

Specifically, if using an input with icon, the HTML markup is of course slightly different as class names have changed:

<div class="input-group" data-datepicker="true">
    <input name="date" type="text" class="form-control" />
    <span class="input-group-addon"><i class="icon-calendar"></i></span>
</div>

It seems because of this, you need to use a selector that points directly to the input element itself NOT the parent container (which is what the auto generated HTML on the demo page suggests).

$('*[data-datepicker="true"] input[type="text"]').datepicker({
    todayBtn: true,
    orientation: "top left",
    autoclose: true,
    todayHighlight: true
});

Having done this you will probably also want to add a listener for clicking/tapping on the icon so it sets focus on the text input when clicked (which is the behaviour when using this plugin with TB 2.x by default).

$(document).on('touch click', '*[data-datepicker="true"] .input-group-addon', function(e){
    $('input[type="text"]', $(this).parent()).focus();
});

NB: I just use a data-datepicker boolean attribute because the class name 'datepicker' is reserved by the plugin and I already use 'date' for styling elements.

You might try turning off pooling, which is enabled by default. See this discussion for more information.

import pyodbc
pyodbc.pooling = False
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest') 

csr = conn.cursor()  
csr.close()
del csr

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

public void launchPlayStore(Context context, String packageName) {
    Intent intent = null;
    try {
            intent = new Intent(Intent.ACTION_VIEW);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.setData(Uri.parse("market://details?id=" + packageName));
            context.startActivity(intent);
        } catch (android.content.ActivityNotFoundException anfe) {
            startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + packageName)));
        }
    }

       }
       catch (IOException)
       {
       }
    }

I believe that most of these answers are for bootstrap 2. I ran into the same issue for bootstrap 3 and wanted to share my fix. Like my previous answer for bootstrap 2, this will still do an opacity fade, but will NOT do the slide transition.

You can either change the modals.less or the theme.css files, depending on your workflow. If you haven't spent any quality time with less, I'd highly recommend it.

for less, find the following code in MODALS.less

&.fade .modal-dialog {
  .translate(0, -25%);
  .transition-transform(~"0.3s ease-out");
}
&.in .modal-dialog { .translate(0, 0)}

then change the -25% to 0%

Alternatively, if you're using just the css, find the following in theme.css:

.modal.fade .modal-dialog {
  -webkit-transform: translate(0, -25%);
  -ms-transform: translate(0, -25%);
  transform: translate(0, -25%);
  -webkit-transition: -webkit-transform 0.3s ease-out;
  -moz-transition: -moz-transform 0.3s ease-out;
  -o-transition: -o-transform 0.3s ease-out;
  transition: transform 0.3s ease-out;
}

and then change the -25% to 0%.
