I am surprised that there isn't more information posted about Solr. Solr is quite similar to Sphinx but has more advanced features (AFAIK as I haven't used Sphinx -- only read about it).

The answer at the link below details a few things about Sphinx which also applies to Solr. Comparison of full text search engine - Lucene, Sphinx, Postgresql, MySQL?

Solr also provides the following additional features:

1. Supports replication
2. Multiple cores (think of these as separate databases with their own configuration and own indexes)
3. Boolean searches
4. Highlighting of keywords (fairly easy to do in application code if you have regex-fu; however, why not let a specialized tool do a better job for you)
5. Update index via XML or delimited file
6. Communicate with the search server via HTTP (it can even return Json, Native PHP/Ruby/Python)
7. PDF, Word document indexing
8. Dynamic fields
9. Facets
10. Aggregate fields
11. Stop words, synonyms, etc.
12. More Like this...
13. Index directly from the database with custom queries
14. Auto-suggest
15. Cache Autowarming
16. Fast indexing (compare to MySQL full-text search indexing times) -- Lucene uses a binary inverted index format.
17. Boosting (custom rules for increasing relevance of a particular keyword or phrase, etc.)
18. Fielded searches (if a search user knows the field he/she wants to search, they narrow down their search by typing the field, then the value, and ONLY that field is searched rather than everything -- much better user experience)

BTW, there are tons more features; however, I've listed just the features that I have actually used in production. BTW, out of the box, MySQL supports #1, #3, and #11 (limited) on the list above. For the features you are looking for, a relational database isn't going to cut it. I'd eliminate those straight away.

Also, another benefit is that Solr (well, Lucene actually) is a document database (e.g. NoSQL) so many of the benefits of any other document database can be realized with Solr. In other words, you can use it for more than just search (i.e. Performance). Get creative with it :)

Press Ctrl+,

Then you will see a docked window under name of "Go to all"

This a picture of the "Go to all" in my IDE

1. Make sure you have full-text search feature installed.

   

2. Create full-text search catalog.

    use AdventureWorks
    create fulltext catalog FullTextCatalog as default
   
    select *
    from sys.fulltext_catalogs
   

3. Create full-text search index.

    create fulltext index on Production.ProductDescription(Description)
    key index PK_ProductDescription_ProductDescriptionID
   

   Before you create the index, make sure:
   - you don't already have full-text search index on the table as only one full-text search index allowed on a table
   - a unique index exists on the table. The index must be based on single-key column, that does not allow NULL.
   - full-text catalog exists. You have to specify full-text catalog name explicitly if there is no default full-text catalog.

You can do step 2 and 3 in SQL Sever Management Studio. In object explorer, right click on a table, select Full-Text index menu item and then Define Full-Text Index... sub-menu item. Full-Text indexing wizard will guide you through the process. It will also create a full-text search catalog for you if you don't have any yet.

You can find more info at MSDN

If you use UPPER(text), the like '%lah%' will always return zero results. Use '%LAH%'.

Here is a query which you can use to search for anything in from your database as a search result ,

SELECT * FROM tbl_customer 
    WHERE CustomerName LIKE '%".$search."%'
    OR Address LIKE '%".$search."%' 
    OR City LIKE '%".$search."%' 
    OR PostalCode LIKE '%".$search."%' 
    OR Country LIKE '%".$search."%'

Using this code will help you search in for multiple columns easily

You need some tools like pdf2text to first convert your pdf to a text file and then search inside the text. (You will probably miss some information or symbols).

If you are using a programming language there are probably pdf libraries written for this purpose. e.g. http://search.cpan.org/dist/CAM-PDF/ for Perl

If you don't want to install Non-Microsoft tools, please download STRINGS.EXE from Microsoft Sysinternals and make a procedure like this one:

@echo off
if '%1' == '' goto NOPARAM
if '%2' == '' goto NOPARAM
if not exist %1 goto NOFOLDER

echo ------------------------------------------
echo - %1 : folder
echo - %2 : string to be searched in the folder
echo - PLEASE WAIT FOR THE RESULTS ...
strings -s %1\* | findstr /i %2 > grep.txt
notepad.exe grep.txt

goto END

:NOPARAM rem - input command not correct
echo ====================================
echo Usage of GREP.CMD:
echo   Grep "SearchFolder" SearchString
echo Please specify all parameters
echo ====================================
goto END

:NOFOLDER
echo Folder %1 does not exist
goto END

:END rem - exit

Just adding for who might need.. Don't forget to alter the table!

ALTER TABLE table_name ADD FULLTEXT(column_name);

i'm not sure if i understand you, but to query the source code of your triggers, procedures, package and functions you can try with the "user_source" table.

select * from user_source

Or File::Find

use File::Find;
finddepth(\&wanted, '/some/path/to/dir');
sub wanted { print };

It'll go through subdirectories if they exist.

Maybe i dont understand , why cant you just get the element.text and then convert it before using it ? for instance (dont know why you would do this but...) find all label elements of the web page and iterate between them until you find one called MyText

        avail = []
        avail = driver.find_elements_by_class_name("label");
        for i in avail:
                if  i.text == "MyText":

Convert the string from i and do whatever you wanted to do ... maybe im missing something in the original message ? or was this what you were looking for ?

I've been battling this kind of problem for a while, and I think I've come up with a reliable solution.

It's pretty difficult to know for sure that this.getActivity() isn't going to return null for a Fragment, especially if you're dealing with any kind of network behaviour which gives your code ample time to withdraw Activity references.

In the solution below, I declare a small management class called the ActivityBuffer. Essentially, this class deals with maintaining a reliable reference to an owning Activity, and promising to execute Runnables within a valid Activity context whenever there's a valid reference available. The Runnables are scheduled for execution on the UI Thread immediately if the Context is available, otherwise execution is deferred until that Context is ready.

/** A class which maintains a list of transactions to occur when Context becomes available. */
public final class ActivityBuffer {

    /** A class which defines operations to execute once there's an available Context. */
    public interface IRunnable {
        /** Executes when there's an available Context. Ideally, will it operate immediately. */
        void run(final Activity pActivity);
    }

    /* Member Variables. */
    private       Activity        mActivity;
    private final List<IRunnable> mRunnables;

    /** Constructor. */
    public ActivityBuffer() {
        // Initialize Member Variables.
        this.mActivity  = null;
        this.mRunnables = new ArrayList<IRunnable>();
    }

    /** Executes the Runnable if there's an available Context. Otherwise, defers execution until it becomes available. */
    public final void safely(final IRunnable pRunnable) {
        // Synchronize along the current instance.
        synchronized(this) {
            // Do we have a context available?
            if(this.isContextAvailable()) {
                // Fetch the Activity.
                final Activity lActivity = this.getActivity();
                // Execute the Runnable along the Activity.
                lActivity.runOnUiThread(new Runnable() { @Override public final void run() { pRunnable.run(lActivity); } });
            }
            else {
                // Buffer the Runnable so that it's ready to receive a valid reference.
                this.getRunnables().add(pRunnable);
            }
        }
    }

    /** Called to inform the ActivityBuffer that there's an available Activity reference. */
    public final void onContextGained(final Activity pActivity) {
        // Synchronize along ourself.
        synchronized(this) {
            // Update the Activity reference.
            this.setActivity(pActivity);
            // Are there any Runnables awaiting execution?
            if(!this.getRunnables().isEmpty()) {
                // Iterate the Runnables.
                for(final IRunnable lRunnable : this.getRunnables()) {
                    // Execute the Runnable on the UI Thread.
                    pActivity.runOnUiThread(new Runnable() { @Override public final void run() {
                        // Execute the Runnable.
                        lRunnable.run(pActivity);
                    } });
                }
                // Empty the Runnables.
                this.getRunnables().clear();
            }
        }
    }

    /** Called to inform the ActivityBuffer that the Context has been lost. */
    public final void onContextLost() {
        // Synchronize along ourself.
        synchronized(this) {
            // Remove the Context reference.
            this.setActivity(null);
        }
    }

    /** Defines whether there's a safe Context available for the ActivityBuffer. */
    public final boolean isContextAvailable() {
        // Synchronize upon ourself.
        synchronized(this) {
            // Return the state of the Activity reference.
            return (this.getActivity() != null);
        }
    }

    /* Getters and Setters. */
    private final void setActivity(final Activity pActivity) {
        this.mActivity = pActivity;
    }

    private final Activity getActivity() {
        return this.mActivity;
    }

    private final List<IRunnable> getRunnables() {
        return this.mRunnables;
    }

}

In terms of its implementation, we must take care to apply the life cycle methods to coincide with the behaviour described above by Pawan M:

public class BaseFragment extends Fragment {

    /* Member Variables. */
    private ActivityBuffer mActivityBuffer;

    public BaseFragment() {
        // Implement the Parent.
        super();
        // Allocate the ActivityBuffer.
        this.mActivityBuffer = new ActivityBuffer();
    }

    @Override
    public final void onAttach(final Context pContext) {
        // Handle as usual.
        super.onAttach(pContext);
        // Is the Context an Activity?
        if(pContext instanceof Activity) {
            // Cast Accordingly.
            final Activity lActivity = (Activity)pContext;
            // Inform the ActivityBuffer.
            this.getActivityBuffer().onContextGained(lActivity);
        }
    }

    @Deprecated @Override
    public final void onAttach(final Activity pActivity) {
        // Handle as usual.
        super.onAttach(pActivity);
        // Inform the ActivityBuffer.
        this.getActivityBuffer().onContextGained(pActivity);
    }

    @Override
    public final void onDetach() {
        // Handle as usual.
        super.onDetach();
        // Inform the ActivityBuffer.
        this.getActivityBuffer().onContextLost();
    }

    /* Getters. */
    public final ActivityBuffer getActivityBuffer() {
        return this.mActivityBuffer;
    }

}

Finally, in any areas within your Fragment that extends BaseFragment that you're untrustworthy about a call to getActivity(), simply make a call to this.getActivityBuffer().safely(...) and declare an ActivityBuffer.IRunnable for the task!

The contents of your void run(final Activity pActivity) are then guaranteed to execute along the UI Thread.

The ActivityBuffer can then be used as follows:

this.getActivityBuffer().safely(
  new ActivityBuffer.IRunnable() {
    @Override public final void run(final Activity pActivity) {
       // Do something with guaranteed Context.
    }
  }
);

I had a similar problem, and found a way to work around it.

The problem is the way Laravel's query builder handles aggregates. It takes the first result returned and then returns the 'aggregate' value. This is usually fine, but when you combine count with groupBy you're returning a count per grouped item. So the first row's aggregate is just a count of the first group (so something low like 1 or 2 is likely).

So Laravel's count is out, but I combined the Laravel query builder with some raw SQL to get an accurate count of my grouped results.

For your example, I expect the following should work (and let you avoid the get):

$query = $ad->getcodes()->groupby('pid')->distinct();
$count = count(\DB::select($query->toSql(), $query->getBindings()));

If you want to make sure you're not wasting time selecting all the columns, you can avoid that when building your query:

 $query = $ad->select(DB::raw(1))->getcodes()->groupby('pid')->distinct();

Try to think in terms of a model and what happens to that model when a checkbox is checked.

Assuming that each checkbox is bound to a field on the model with ng-model then the property on the model is changed whenever a checkbox is clicked:

<input type='checkbox' ng-model='fooSelected' />
<input type='checkbox' ng-model='baaSelected' />

and in the controller:

$scope.fooSelected = false;
$scope.baaSelected = false;

The next button should only be available under certain circumstances so add the ng-disabled directive to the button:

<button type='button' ng-disabled='nextButtonDisabled'></button>

Now the next button should only be available when either fooSelected is true or baaSelected is true and we need to watch any changes to these fields to make sure that the next button is made available or not:

$scope.$watch('[fooSelected,baaSelected]', function(){
    $scope.nextButtonDisabled = !$scope.fooSelected && !scope.baaSelected;
}, true );

The above assumes that there are only a few checkboxes that affect the availability of the next button but it could be easily changed to work with a larger number of checkboxes and use $watchCollection to check for changes.

I just used Jonas' example above and created full list of 0 to 24 errorlevels. Other post is correct that net start and net stop only use errorlevel 0 for success and 2 for failure.

But this is what worked for me:

net stop postgresql-9.1
if %errorlevel% == 2 echo Access Denied - Could not stop service
if %errorlevel% == 0 echo Service stopped successfully
echo Errorlevel: %errorlevel%

Change stop to start and works in reverse.

A bit late to the party but I decided to create my own one after looking at @Alex Macmillan answers and that was by passing two extra parameters; the position in which to place the scripts such as or and setting up the async to true/false, here it is:

import { useEffect } from 'react';

const useScript = (url, position, async) => {
  useEffect(() => {
    const placement = document.querySelector(position);
    const script = document.createElement('script');

    script.src = url;
    script.async = typeof async === 'undefined' ? true : async;

    placement.appendChild(script);

    return () => {
      placement.removeChild(script);
    };
  }, [url]);
};

export default useScript;

The way to call it is exactly the same as shown in the accepted answer of this post but with two extra(again) parameters:

// First string is your URL
// Second string can be head or body
// Third parameter is true or false.
useScript("string", "string", bool);

I think you're mixed up between PATH and PYTHONPATH. All you have to do to run a 'script' is have it's parental directory appended to your PATH variable. You can test this by running

which myscript.py

Also, if myscripy.py depends on custom modules, their parental directories must also be added to the PYTHONPATH variable. Unfortunately, because the designers of python were clearly on drugs, testing your imports in the repl with the following will not guarantee that your PYTHONPATH is set properly for use in a script. This part of python programming is magic and can't be answered appropriately on stackoverflow.

$python
Python 2.7.8 blahblahblah
...
>from mymodule.submodule import ClassName
>test = ClassName()
>^D
$myscript_that_needs_mymodule.submodule.py

  File "/path/to/myscript_that_needs_mymodule.submodule.py", line 5, in <module>
    from mymodule.submodule import ClassName
ImportError: No module named submodule

I used this below if this is what you are thinking. It it worked well for me.

<?php
    include $_SERVER['DOCUMENT_ROOT']."/head_lib.php";
?>

What I was trying to do was pulla file called /head_lib.php from the root folder. It would not pull anything to build the webpage. The header, footer and other key features in sub directories would never show up. Until I did above it worked like a champ.

Specify the LANG and LC_ALL environment variables using -e when running your command:

docker run -e LANG=C.UTF-8 -e LC_ALL=C.UTF-8 -it --rm <yourimage> <yourcommand>

It's not necessary to modify the Dockerfile.

I had a similar issue and noted that the default cmd on Windows Server 2012, was running the x64 one.

For Windows 7, Windows 8, Windows 10, Windows Server 2008 R2 or Windows Server 2012, run the following commands as Administrator:

x86 (32 bit)
Open C:\Windows\SysWOW64\cmd.exe
Run the command powershell Set-ExecutionPolicy RemoteSigned

x64 (64 bit)
Open C:\Windows\system32\cmd.exe
Run the command powershell Set-ExecutionPolicy RemoteSigned

You can check mode using

• In CMD: echo %PROCESSOR_ARCHITECTURE%
• In Powershell: [Environment]::Is64BitProcess

References:
MSDN - Windows PowerShell execution policies
Windows - 32bit vs 64bit directory explanation

i'd recommend using tables for this problem. i'm having a similar issue and as long as the table is just used to display some data and not for the main page layout it is fine.

FWIW the only thing that worked for me in PR builds was ${CHANGE_BRANCH}

(may not work on master, haven't seen that yet)

Use the following JS:

$(document).ready(function () {
    $("#btnsubmit").click(function () {

             $.ajax({
                 type: "POST",
                 url: '/Plan/PlanManage',     //your action
                 data: $('#PlanForm').serialize(),   //your form name.it takes all the values of model               
                 dataType: 'json',
                 success: function (result) {
                     console.log(result);
                 }
             })
        return false;
    });
});

and the following code on your controller:

[HttpPost]
public string PlanManage(Plan objplan)  //model plan
{
}

The thing with compiling two .cpp files at the same time, it doesnt't mean they "know" about eachother. You will have to create a file, the "tells" your File1.cpp, there actually are functions and classes like ClassTwo. This file is called header-file and often doesn't include any executable code. (There are exception, e.g. for inline functions, but forget them at first) They serve a declarative need, just for telling, which functions are available.

When you have your File2.cpp and include it into your File1.cpp, you see a small problem: There is the same code twice: One in the File1.cpp and one in it's origin, File2.cpp.

Therefore you should create a header file, like File1.hpp or File1.h (other names are possible, but this is simply standard). It works like the following:

//File1.cpp

void SomeFunc(char c) //Definition aka Implementation
{
//do some stuff
}

//File1.hpp

void SomeFunc(char c); //Declaration aka Prototype

And for a matter of clean code you might add the following to the top of File1.cpp:

#include "File1.hpp"

And the following, surrounding File1.hpp's code:

#ifndef FILE1.HPP_INCLUDED
#define FILE1.HPP_INCLUDED
//
//All your declarative code
//
#endif

This makes your header-file cleaner, regarding to duplicate code.

Sorry to tell you screencap just a simple command, only accept few arguments, but none of them can save time for you, here is the -h help output.

$ adb shell screencap -h
usage: screencap [-hp] [-d display-id] [FILENAME]
-h: this message
-p: save the file as a png.
-d: specify the display id to capture, default 0.
If FILENAME ends with .png it will be saved as a png.
If FILENAME is not given, the results will be printed to stdout.

Besides the command screencap, there is another command screenshot, I don't know why screenshot was removed from Android 5.0, but it's avaiable below Android 4.4, you can check the source from here. I didn't make my comparison which is faster between these two commands, but you can give your try in your real environment and make the final decision.

This is the same of the accepted and most voted response but this snipped used Snackbar instead of Toast.

boolean doubleBackToExitPressedOnce = false;

    @Override
    public void onBackPressed() {
        if (doubleBackToExitPressedOnce) {
            super.onBackPressed();
            return;
        }

        this.doubleBackToExitPressedOnce = true;
        Snackbar.make(content, "Please click BACK again to exit", Snackbar.LENGTH_SHORT)
                .setAction("Action", null).show();

I received inspiration from the Angular Material docs on buttons: https://material.angular.io/components/button/examples

This is the only solution that worked for me after trying several of those above. Switch to your c:\users folder and search for .sln and then remove all .sln files that have your project name. Then restart your computer and rebuild the solution (F5) and it worked!

The most upvoted answer can be improved.

Let me refer to GNU Make manual "Setting variables" and "Flavors", and add some comments.

Recursively expanded variables

The value you specify is installed verbatim; if it contains references to other variables, these references are expanded whenever this variable is substituted (in the course of expanding some other string). When this happens, it is called recursive expansion.

foo = $(bar)

The catch: foo will be expanded to the value of $(bar) each time foo is evaluated, possibly resulting in different values. Surely you cannot call it "lazy"! This can surprise you if executed on midnight:

# This variable is haunted!
WHEN = $(shell date -I)

something:
    touch $(WHEN).flag

# If this is executed on 00:00:00:000, $(WHEN) will have a different value!
something-else-later: something
    test -f $(WHEN).flag || echo "Boo!"

Simply expanded variable

VARIABLE := value
VARIABLE ::= value

Variables defined with ‘:=’ or ‘::=’ are simply expanded variables.

Simply expanded variables are defined by lines using ‘:=’ or ‘::=’ [...]. Both forms are equivalent in GNU make; however only the ‘::=’ form is described by the POSIX standard [...] 2012.

The value of a simply expanded variable is scanned once and for all, expanding any references to other variables and functions, when the variable is defined.

Not much to add. It's evaluated immediately, including recursive expansion of, well, recursively expanded variables.

The catch: If VARIABLE refers to ANOTHER_VARIABLE:

VARIABLE := $(ANOTHER_VARIABLE)-yohoho

and ANOTHER_VARIABLE is not defined before this assignment, ANOTHER_VARIABLE will expand to an empty value.

Assign if not set

FOO ?= bar

is equivalent to

ifeq ($(origin FOO), undefined)
FOO = bar
endif

where $(origin FOO) equals to undefined only if the variable was not set at all.

The catch: if FOO was set to an empty string, either in makefiles, shell environment, or command line overrides, it will not be assigned bar.

Appending

VAR += bar

Appending:

When the variable in question has not been defined before, ‘+=’ acts just like normal ‘=’: it defines a recursively-expanded variable. However, when there is a previous definition, exactly what ‘+=’ does depends on what flavor of variable you defined originally.

So, this will print foo bar:

VAR = foo
# ... a mile of code
VAR += $(BAR)
BAR = bar
$(info $(VAR))

but this will print foo:

VAR := foo
# ... a mile of code
VAR += $(BAR)
BAR = bar
$(info $(VAR))

The catch is that += behaves differently depending on what type of variable VAR was assigned before.

Multiline values

The syntax to assign multiline value to a variable is:

define VAR_NAME :=
line
line
endef

or

define VAR_NAME =
line
line
endef

Assignment operator can be omitted, then it creates a recursively-expanded variable.

define VAR_NAME
line
line
endef

The last newline before endef is removed.

Bonus: the shell assignment operator ‘!=’

 HASH != printf '\043'

is the same as

HASH := $(shell printf '\043')

Don't use it. $(shell) call is more readable, and the usage of both in a makefiles is highly discouraged. At least, $(shell) follows Joel's advice and makes wrong code look obviously wrong.

libconfig is very easy, and what's better, it uses a pseudo json notation for better readability.

Easy to install on Ubuntu: sudo apt-get install libconfig++8-dev

and link: -lconfig++

You can use the HSL color model to create your colors.

If all you want is differing hues (likely), and slight variations on lightness or saturation, you can distribute the hues like so:

// assumes hue [0, 360), saturation [0, 100), lightness [0, 100)

for(i = 0; i < 360; i += 360 / num_colors) {
    HSLColor c;
    c.hue = i;
    c.saturation = 90 + randf() * 10;
    c.lightness = 50 + randf() * 10;

    addColor(c);
}

If Data Is not Loaded From savedInstanceState use following code.
The problem is url call is not to complete fully so, check if data is loaded then to show the instanceState value.

//suppose data is not Loaded to savedInstanceState at 1st swipe
if (savedInstanceState == null && !mAlreadyLoaded){
    mAlreadyLoaded = true;
    GetStoryData();//Url Call
} else {
    if (listArray != null) {  //Data Array From JsonArray(ListArray)
        System.out.println("LocalData  " + listArray);
        view.findViewById(R.id.progressBar).setVisibility(View.GONE);
    }else{
        GetStoryData();//Url Call
    }
}

To start a particular service defined in your docker-compose file. for example if your have a docker-compose.yml

docker-compose start db  

given a compose file like as:

version: '3.3'

services:
   db:
     image: mysql:5.7
     ports:
       - "3306:3306"
     volumes:
       - ./db_data:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: yourPassword
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: yourPassword

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "80:80"
     volumes:
       - ./l3html:/var/www/html
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: yourPassword
volumes:
    db_data:
    l3html:

Some times you want to start mySQL only (sometimes you just want to populate a database) before you start your entire suite.

Changing

RestResponse response = client.Execute(request);

to

IRestResponse response = client.Execute(request);

worked for me.

As far as I know nothing like sed is bundled with windows. However, sed is available for Windows in several different forms, including as part of Cygwin, if you want a full POSIX subsystem, or as a Win32 native executable if you want to run just sed on the command line.

Sed for Windows (GnuWin32 Project)

If it needs to be native to Windows then the only other thing I can suggest would be to use a scripting language supported by Windows without add-ons, such as VBScript.

print "Matched!\n" if ($str1 eq $str2)

Perl has seperate string comparison and numeric comparison operators to help with the loose typing in the language. You should read perlop for all the different operators.

Why not use them in the Users directory in the .bash_profile file, so you don't have to push any files with your variables to production?

In Java
Integer/Integer = Integer
Integer/Double = Double//Either of numerator or denominator must be floating point number
1/10 = 0
1.0/10 = 0.1
1/10.0 = 0.1

Just type cast either of them.

Try something like this inside ThisOutlookSession:

Private Sub Application_NewMail()
    Call Your_main_macro
End Sub

My outlook vba just fired when I received an email and had that application event open.

Edit: I just tested a hello world msg box and it ran after being called in the application_newmail event when an email was received.

<input type="button" /> buttons will not submit a form - they don't do anything by default. They're generally used in conjunction with JavaScript as part of an AJAX application.

<input type="submit"> buttons will submit the form they are in when the user clicks on them, unless you specify otherwise with JavaScript.

The SciPy webpage used to provide build and installation instructions, but the instructions there now rely on OS binary distributions. To build SciPy (and NumPy) on operating systems without precompiled packages of the required libraries, you must build and then statically link to the Fortran libraries BLAS and LAPACK:

mkdir -p ~/src/
cd ~/src/
wget http://www.netlib.org/blas/blas.tgz
tar xzf blas.tgz
cd BLAS-*

## NOTE: The selected Fortran compiler must be consistent for BLAS, LAPACK, NumPy, and SciPy.
## For GNU compiler on 32-bit systems:
#g77 -O2 -fno-second-underscore -c *.f                     # with g77
#gfortran -O2 -std=legacy -fno-second-underscore -c *.f    # with gfortran
## OR for GNU compiler on 64-bit systems:
#g77 -O3 -m64 -fno-second-underscore -fPIC -c *.f                     # with g77
gfortran -O3 -std=legacy -m64 -fno-second-underscore -fPIC -c *.f    # with gfortran
## OR for Intel compiler:
#ifort -FI -w90 -w95 -cm -O3 -unroll -c *.f

# Continue below irrespective of compiler:
ar r libfblas.a *.o
ranlib libfblas.a
rm -rf *.o
export BLAS=~/src/BLAS-*/libfblas.a

Execute only one of the five g77/gfortran/ifort commands. I have commented out all, but the gfortran which I use. The subsequent LAPACK installation requires a Fortran 90 compiler, and since both installs should use the same Fortran compiler, g77 should not be used for BLAS.

Next, you'll need to install the LAPACK stuff. The SciPy webpage's instructions helped me here as well, but I had to modify them to suit my environment:

mkdir -p ~/src
cd ~/src/
wget http://www.netlib.org/lapack/lapack.tgz
tar xzf lapack.tgz
cd lapack-*/
cp INSTALL/make.inc.gfortran make.inc          # On Linux with lapack-3.2.1 or newer
make lapacklib
make clean
export LAPACK=~/src/lapack-*/liblapack.a

Update on 3-Sep-2015: Verified some comments today (thanks to all): Before running make lapacklib edit the make.inc file and add -fPIC option to OPTS and NOOPT settings. If you are on a 64bit architecture or want to compile for one, also add -m64. It is important that BLAS and LAPACK are compiled with these options set to the same values. If you forget the -fPIC SciPy will actually give you an error about missing symbols and will recommend this switch. The specific section of make.inc looks like this in my setup:

FORTRAN  = gfortran 
OPTS     = -O2 -frecursive -fPIC -m64
DRVOPTS  = $(OPTS)
NOOPT    = -O0 -frecursive -fPIC -m64
LOADER   = gfortran

On old machines (e.g. RedHat 5), gfortran might be installed in an older version (e.g. 4.1.2) and does not understand option -frecursive. Simply remove it from the make.inc file in such cases.

The lapack test target of the Makefile fails in my setup because it cannot find the blas libraries. If you are thorough you can temporarily move the blas library to the specified location to test the lapack. I'm a lazy person, so I trust the devs to have it working and verify only in SciPy.

Its in the comments of the answers but nobody has posted this as the actual solution.

You just need to add a using statement at the top:

using Microsoft.AspNet.Identity;

Starting Scala 2.13, the groupMapReduce method does that in one pass through the list:

// val seq = Seq("apple", "oranges", "apple", "banana", "apple", "oranges", "oranges")
seq.groupMapReduce(identity)(_ => 1)(_ + _)
// immutable.Map[String,Int] = Map(banana -> 1, oranges -> 3, apple -> 3)
seq.groupMapReduce(identity)(_ => 1)(_ + _)("apple")
// Int = 3

This:

• groups list elements (group part of groupMapReduce)

• maps each grouped value occurrence to 1 (map part of groupMapReduce)

• reduces values within a group of values (_ + _) by summing them (reduce part of groupMapReduce).

This is a one-pass version of what can be translated by:

seq.groupBy(identity).mapValues(_.map(_ => 1).reduce(_ + _))

Load environment variables from a file you create at runtime.

export MYVAR="my_var_outside"
cat > build/env.sh <<EOF
MYVAR=${MYVAR}
EOF

... then in the Dockerfile

ADD build /build
RUN /build/test.sh

where test.sh loads MYVAR from env.sh

#!/bin/bash
. /build/env.sh
echo $MYVAR > /tmp/testfile

in the video source change the type to "video/quicktime"

<video width="400" controls Autoplay=autoplay>
  <source src="D:/mov1.mov" type="video/quicktime">
</video>

AFAIK, there is nothing built in for searching all columns. You can use Find only against the primary key. Select needs specified columns. You can perhaps use LINQ, but ultimately this just does the same looping. Perhaps just unroll it yourself? It'll be readable, at least.

i would advice to create table with unique name before bulk inserting.

In Python 3, I was able to do this:

import os
dir = "/path/to/files/"

#List all files immediately under this folder:
print ( next( os.walk(dir) )[2] )

#List all folders immediately under this folder:
print ( next( os.walk(dir) )[1] )

The netdom.exe command line program can be used. This is available from the Windows XP Support Tools or Server 2003 Support Tools (both on the installation CD).

Usage guidelines here

Find out two pieces of information

• Whats the hostname or IP of the target ssh server
• What port is the ssh daemon listening on (default is port 22)

$> telnet <hostname or ip> <port>

Assuming the daemon is up and running and listening on that port it should etablish a telnet session. Likely causes:

• The ssh daemon is not running
• The host is blocking the target port with its software firewall
• Some intermediate network device is blocking or filtering the target port
• The ssh daemon is listening on a non standard port
• A TCP wrapper is configured and is filtering out your source host

You can use the below code for creating a TextBox as read-only.

Method 1

 @Html.TextBoxFor(model => model.Fields[i].TheField, new { @readonly = true })

Method 2

@Html.TextBoxFor(model => model.Fields[i].TheField, new { htmlAttributes = new {disabled = "disabled"}})

In my case i had the error sdk location not found

What i did: I went to the cloned project from git opened the project directory opened the app directory inside the project copied the local.properties file and then pasted it in the project directory Then it worked

If you have Excel 2010 you can copy your data into another column, than select it and choose Data -> Remove Duplicates. You can then write =COUNTIF($A$1:$A$100,B1) next to it and copy the formula down. This assumes you have your values in range A1:A100 and the de-duplicated values are in column B.

if (/^\s+$/.test(myString))
{
      //string contains only whitespace
}

this checks for 1 or more whitespace characters, if you it to also match an empty string then replace + with *.

I'm using gcc as a preprocessor (for html files.) It does just what you want. It expands "#--" directives, then outputs a readable file. (NONE of the other C/HTML preprocessors I've tried do this- they concatenate lines, choke on special characters, etc.) Asuming you have gcc installed, the command line is:

gcc -E -x c -P -C -traditional-cpp code_before.cpp > code_after.cpp

(Doesn't have to be 'cpp'.) There's an excellent description of this usage at http://www.cs.tut.fi/~jkorpela/html/cpre.html.

The "-traditional-cpp" preserves whitespace & tabs.

Above solutions not helped me, but I resolve same issue by next way

private setHeaders(params) {

Few answers that may be useful, especially if you have dynamic content.

$('#dialogueForm').live("dialogclose", function(){
   //your code to run on dialog close
});

Or, when opening the modal, have a callback.

$( "#dialogueForm" ).dialog({
              autoOpen: false,
              height: "auto",
              width: "auto",
              modal: true,
                my: "center",
                at: "center",
                of: window,
              close : function(){
                  // functionality goes here
              }  
              });

firstOrNew will create record if not exist and updating a row if already exist. You can also use updateOrCreate here is the full example

$flight = App\Flight::updateOrCreate(
    ['departure' => 'Oakland', 'destination' => 'San Diego'],
    ['price' => 99]
); 

If there's a flight from Oakland to San Diego, set the price to $99. if not exist create new row

Reference Doc here: (https://laravel.com/docs/5.5/eloquent)

use json library

import json
json.dumps(list)

by the way, you might consider changing variable list to another name, list is the builtin function for a list creation, you may get some unexpected behaviours or some buggy code if you don't change the variable name.

Using Bundling and Minification also helps you improve the performance. It basically reduces the page loading time.

Try this:

 git fetch --all
 git reset --hard origin/master

Explanation:

git fetch downloads the latest from remote without trying to merge or rebase anything.

I think you should check sending your messages using the fan-out exchanger. That way you willl receiving the same message for differents consumers, under the table RabbitMQ is creating differents queues for each one of this new consumers/subscribers.

Javax used to be only for extensions. Yet later sun added it to the java libary forgetting to remove the x. Developers started making code with javax. Yet later on in time suns decided to change it to java. Developers didn't like the idea because they're code would be ruined... so javax was kept.

It's true, they are both - or more precisely, they are "inline block" elements. This means that they flow inline like text, but also have a width and height like block elements.

You're giving parameters to your program instead to Java. Use

java -Dtest="true" -jar myApplication.jar 

instead.

Consider using

"true".equalsIgnoreCase(System.getProperty("test"))

to avoid the NPE. But do not use "Yoda conditions" always without thinking, sometimes throwing the NPE is the right behavior and sometimes something like

System.getProperty("test") == null || System.getProperty("test").equalsIgnoreCase("true")

is right (providing default true). A shorter possibility is

!"false".equalsIgnoreCase(System.getProperty("test"))

but not using double negation doesn't make it less hard to misunderstand.

This should give you the current date minus 1 year:

For me, I have to run

sudo dpkg --add-architecture i386

before running Mike Tang's answer. Otherwise, I can't install ia32-libs.

A data contract is a formal agreement between a service and a client that abstractly describes the data to be exchanged.

Data contract can be explicit or implicit. Simple type such as int, string etc has an implicit data contract. User defined object are explicit or Complex type, for which you have to define a Data contract using [DataContract] and [DataMember] attribute.

A data contract can be defined as follows:

• It describes the external format of data passed to and from service operations

• It defines the structure and types of data exchanged in service messages

• It maps a CLR type to an XML Schema
• It defines how data types are serialized and deserialized. Through serialization, you convert an object into a sequence of bytes that can be transmitted over a network. Through deserialization, you reassemble an object from a sequence of bytes that you receive from a calling application.
• It is a versioning system that allows you to manage changes to structured data

We need to include System.Runtime.Serialization reference to the project. This assembly holds the DataContract and DataMember attribute.

$('#foo > div').size()

:goto 21490 will take you to the 21490th byte in the buffer.

Based on William McBrine's answer, here is a solution for fixed-length strings which is 9% faster for my use case:

import itertools
import struct
def make_strxor(size):
    def strxor(a, b, izip=itertools.izip, pack=struct.pack, unpack=struct.unpack, fmt='%dB' % size):
        return pack(fmt, *(a ^ b for a, b in izip(unpack(fmt, a), unpack(fmt, b))))
    return strxor
strxor_3 = make_strxor(3)
print repr(strxor_3('foo', 'bar'))

This is a very simple solution that returns an array of string with the matches

Swift 3.

internal func stringsMatching(regularExpressionPattern: String, options: NSRegularExpression.Options = []) -> [String] {
        guard let regex = try? NSRegularExpression(pattern: regularExpressionPattern, options: options) else {
            return []
        }

        let nsString = self as NSString
        let results = regex.matches(in: self, options: [], range: NSMakeRange(0, nsString.length))

        return results.map {
            nsString.substring(with: $0.range)
        }
    }

This version also removes the 1px shadow line under the navigation bar:

Swift 5: Put this in your AppDelegate didFinishLaunchingWithOptions

UINavigationBar.appearance().barTintColor = UIColor.black
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false
UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .any, barMetrics: .default)
UINavigationBar.appearance().shadowImage = UIImage()

Steps :

1. Hit http://localhost/phpmyadmin/
2. Select your DB
3. Click on Operations Tab
4. There will be a tab as "Rename database to". Add new name and check Adjust privileges.
5. Click on Go.

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

yum install vixie-cron

And then start it with:

service crond start

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

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

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

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

In jQuery:

In plain Javascript:

var html_string = document.documentElement.outerHTML

You want to use iteritems. This returns an iterator over the dictionary, which gives you a tuple(key, value)

>>> for field, values in fields.iteritems():
...     print field, values
... 
first_names ['foo', 'bar']
last_name ['gravy', 'snowman']

Your problem was that you were looping over fields, which returns the keys of the dictionary.

>>> for field in fields:
...     print field
... 
first_names
last_name

You need to use AND statement in your formula

=IF(AND(IF(NOT(ISBLANK(Q2));TRUE;FALSE);Q2<=R2);"1";"0")

And if both conditions are met, return 1.

You could also add more conditions in your AND statement.

jQuery (original answer).

$('input[type="checkbox"][name="chkBx"]').on('change',function(){
    var getArrVal = $('input[type="checkbox"][name="chkBx"]:checked').map(function(){
        return this.value;
    }).toArray();

    if(getArrVal.length){
        //execute the code
        $('#msg').html(getArrVal.toString());

    } else {
        $(this).prop("checked",true);
        $('#msg').html("At least one value must be checked!");
        return false;

    }

I think that in order to get the request data, bound and validated by the form object, you must use this command :

$form->getViewData();
$form->getClientData(); // Deprecated since version 2.1, to be removed in 2.3.

Instead of using the body you could create a curtain with z-index of 100 (to pick a number) and give the inside element a higher z-index while all other elements have a lower z-index than the curtain.

See working example here: http://jsfiddle.net/Flandre/6JvFk/

jQuery:

$('#curtain').on("click", function(e) {

    $(this).hide();
    alert("clicked ouside of elements that stand out");

});

CSS:

.aboveCurtain
{
    z-index: 200; /* has to have a higher index than the curtain */
    position: relative;
    background-color: pink;
}

#curtain
{
    position: fixed;
    top: 0px;
    left: 0px;
    height: 100%;
    background-color: black;
    width: 100%;
    z-index:100;   
    opacity:0.5 /* change opacity to 0 to make it a true glass effect */
}

open .zshrc with TextEdit

.zshrc is hidden file so unhide it by command+shift+. press

delete file content and type

To change the character set encoding to UTF-8 for the database itself, type the following command at the mysql> prompt. Replace DBNAME with the database name:

ALTER DATABASE DBNAME CHARACTER SET utf8 COLLATE utf8_general_ci;

And about timing:

fn1 <- function (N) {
    for(i in as.numeric(1:N)) { y <- i*i }
}
fn2 <- function (N) {
    i=1
    while (i <= N) {
        y <- i*i
        i <- i + 1
    }
}

system.time(fn1(60000))
# user  system elapsed 
# 0.06    0.00    0.07 
system.time(fn2(60000))
# user  system elapsed 
# 0.12    0.00    0.13

And now we know that for-loop is faster than while-loop. You cannot ignore warnings during timing.

There is a (somewhat) related question on StackOverflow:

• Showing an image with pylab.imshow()

Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.

More generally, the reason for the Exception

TypeError: Invalid dimensions for image data

is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!

You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):

from __future__ import print_function
import numpy as np

def valid_imshow_data(data):
    data = np.asarray(data)
    if data.ndim == 2:
        return True
    elif data.ndim == 3:
        if 3 <= data.shape[2] <= 4:
            return True
        else:
            print('The "data" has 3 dimensions but the last dimension '
                  'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
                  ''.format(data.shape[2]))
            return False
    else:
        print('To visualize an image the data must be 2 dimensional or '
              '3 dimensional, not "{}".'
              ''.format(data.ndim))
        return False

In your case:

>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False

The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.

In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()

import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0)  # or axis=1
plt.imshow(a)
plt.show()

or just use something that accepts 1D arrays like plot:

a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

You need "VT-x supported processor" at least to run Android emulator with Hardware acceleration.

If you have enabled or installed "Hyper-V" in your windows 8 then please remove it and disable the "Hyper threading" and enable "Virtualization".

IEnumerable describes behavior, while List is an implementation of that behavior. When you use IEnumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away.

Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the program. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:

public IEnumerable<Animals> AllSpotted()
{
    return from a in Zoo.Animals
           where a.coat.HasSpots == true
           select a;
}

public IEnumerable<Animals> Feline(IEnumerable<Animals> sample)
{
    return from a in sample
           where a.race.Family == "Felidae"
           select a;
}

public IEnumerable<Animals> Canine(IEnumerable<Animals> sample)
{
    return from a in sample
           where a.race.Family == "Canidae"
           select a;
}

Now you have a method that selects an initial sample ("AllSpotted"), plus some filters. So now you can do this:

var Leopards = Feline(AllSpotted());
var Hyenas = Canine(AllSpotted());

So is it faster to use List over IEnumerable? Only if you want to prevent a query from being executed more than once. But is it better overall? Well in the above, Leopards and Hyenas get converted into single SQL queries each, and the database only returns the rows that are relevant. But if we had returned a List from AllSpotted(), then it may run slower because the database could return far more data than is actually needed, and we waste cycles doing the filtering in the client.

In a program, it may be better to defer converting your query to a list until the very end, so if I'm going to enumerate through Leopards and Hyenas more than once, I'd do this:

List<Animals> Leopards = Feline(AllSpotted()).ToList();
List<Animals> Hyenas = Canine(AllSpotted()).ToList();

Here's how you do it for SQL Server. Someone else can translate it to MySQL. Parsing CSV Values Into Multiple Rows.

SELECT Author, 
NullIf(SubString(',' + Phrase + ',' , ID , CharIndex(',' , ',' + Phrase + ',' , ID) - ID) , '') AS Word 
FROM Tally, Quotes 
WHERE ID <= Len(',' + Phrase + ',') AND SubString(',' + Phrase + ',' , ID - 1, 1) = ',' 
AND CharIndex(',' , ',' + Phrase + ',' , ID) - ID > 0

The idea is to cross join to a predefined table Tally which contains integer 1 through 8000 (or whatever big enough number) and run SubString to find the right ,word, position.

Change:

using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net"))

To:

 using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\Wow6432Node\MySQL AB\MySQL Connector\Net"))

Questions 1 & 2

So basically, first parameter is the object to iterate on. It can be an array or an object. If it is an object like this :

var values = {name: 'misko', gender: 'male'};

Angular will take each value one by one the first one is name, the second is gender.

If your object to iterate on is an array (also possible), like this :

[{ "Name" : "Thomas", "Password" : "thomasTheKing" },
 { "Name" : "Linda", "Password" : "lindatheQueen" }]

Angular.forEach will take one by one starting by the first object, then the second object.

For each of this object, it will so take them one by one and execute a specific code for each value. This code is called the iterator function. forEach is smart and behave differently if you are using an array of a collection. Here is some exemple :

var obj = {name: 'misko', gender: 'male'};
var log = [];
angular.forEach(obj, function(value, key) {
  console.log(key + ': ' + value);
});
// it will log two iteration like this
// name: misko
// gender: male

So key is the string value of your key and value is ... the value. You can use the key to access your value like this : obj['name'] = 'John'

If this time you display an array, like this :

var values = [{ "Name" : "Thomas", "Password" : "thomasTheKing" },
           { "Name" : "Linda", "Password" : "lindatheQueen" }];
angular.forEach(values, function(value, key){
     console.log(key + ': ' + value);
});
// it will log two iteration like this
// 0: [object Object]
// 1: [object Object]

So then value is your object (collection), and key is the index of your array since :

[{ "Name" : "Thomas", "Password" : "thomasTheKing" },
 { "Name" : "Linda", "Password" : "lindatheQueen" }]
// is equal to
{0: { "Name" : "Thomas", "Password" : "thomasTheKing" },
 1: { "Name" : "Linda", "Password" : "lindatheQueen" }}

I hope it answer your question. Here is a JSFiddle to run some code and test if you want : http://jsfiddle.net/ygahqdge/

Debugging your code

The problem seems to come from the fact $http.get() is an asynchronous request.

You send a query on your son, THEN when you browser end downloading it it execute success. BUT just after sending your request your perform a loop using angular.forEach without waiting the answer of your JSON.

You need to include the loop in the success function

var app = angular.module('testModule', [])
    .controller('testController', ['$scope', '$http', function($scope, $http){
    $http.get('Data/info.json').then(function(data){
         $scope.data = data;

         angular.forEach($scope.data, function(value, key){
         if(value.Password == "thomasTheKing")
           console.log("username is thomas");
         });
    });

});

This should work.

Going more deeply

The $http API is based on the deferred/promise APIs exposed by the $q service. While for simple usage patterns this doesn't matter much, for advanced usage it is important to familiarize yourself with these APIs and the guarantees they provide.

You can give a look at deferred/promise APIs, it is an important concept of Angular to make smooth asynchronous actions.

I know DOS and cmd prompt DOES NOT LIKE spaces in folder names. Your code starts with

cd c:\Program files\IIS Express

and it's trying to go to c:\Program in stead of C:\"Program Files"

Change the folder name and *.exe name. Hope this helps

Only static functions are called with class name.

classname::Staicfunction();

Non static functions have to be called using objects.

classname obj;
obj.Somefunction();

This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.

You want to convert it to an object first and then access normally making sure to cast it.

JObject obj = JObject.Parse(json);
string name = (string) obj["Name"];

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

tl;dr

LocalDate.now().format(
    DateTimeFormatter.ofLocalizedDate( FormatStyle.MEDIUM )
                     .withLocale( new Locale( "no" , "NO" ) )
)

The troublesome classes of java.util.Date and SimpleDateFormat are now legacy, supplanted by the java.time classes.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

ZoneId z = ZoneId.of( "America/Montreal" );
LocalDate today = LocalDate.now( z );

DateTimeFormatter

Use DateTimeFormatter to generate strings representing only the date-portion or the time-portion.

The DateTimeFormatter class can automatically localize.

To localize, specify:

• FormatStyle to determine how long or abbreviated should the string be.
• Locale to determine (a) the human language for translation of name of day, name of month, and such, and (b) the cultural norms deciding issues of abbreviation, capitalization, punctuation, and such.

Example:

Locale l = Locale.CANADA_FRENCH ; 
DateTimeFormatter f = DateTimeFormatter.ofLocalizedDate( FormatStyle.FULL ).withLocale( l );
String output = ld.format( f );

Going the other direction, you can parse a localized string.

LocalDate ld = LocalDate.parse( input , f );

Note that the locale and time zone are completely orthogonal issues. You can have a Montréal moment presented in Japanese language or an Auckland New Zealand moment presented in Hindi language.

Another example: Change 6 junio 2012 (Spanish) to 2012-06-06 (standard ISO 8601 format). The java.time classes use ISO 8601 formats by default for parsing/generating strings.

String input = "6 junio 2012";
Locale l = new Locale ( "es" , "ES" );
DateTimeFormatter f = DateTimeFormatter.ofPattern ( "d MMMM uuuu" , l );
LocalDate ld = LocalDate.parse ( input , f );
String output = ld.toString();  // 2012-06-06. 

Peruse formats

Here is some example code for perusing the results of multiple formats in multiple locales, automatically localized.

An EnumSet is an implementation of Set, highly optimized for both low memory usage and fast execution speed when collecting Enum objects. So, EnumSet.allOf( FormatStyle.class ) gives us a collection of all four of the FormatStyle enum objects to loop. For more info, see Oracle Tutorial on enum types.

LocalDate ld = LocalDate.of( 2018 , Month.JANUARY , 23 );

List < Locale > locales = new ArrayList <>( 3 );
locales.add( Locale.CANADA_FRENCH );
locales.add( new Locale( "no" , "NO" ) );
locales.add( Locale.US );

// Or use all locales (almost 800 of them, for about 120K text results).
// Locale[] locales = Locale.getAvailableLocales(); // All known locales. Almost 800 of them.

for ( Locale locale : locales )
{
    System.out.println( "------|  LOCALE: " + locale + " — " + locale.getDisplayName() + "  |----------------------------------" + System.lineSeparator() );

    for ( FormatStyle style : EnumSet.allOf( FormatStyle.class ) )
    {
        DateTimeFormatter f = DateTimeFormatter.ofLocalizedDate( style ).withLocale( locale );
        String output = ld.format( f );
        System.out.println( output );
    }
    System.out.println( "" );
}
System.out.println( "« fin »" + System.lineSeparator() );

Output.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

You can use some different schemes for that. I've always tested for arguments.length:

function myFunc(requiredArg, optionalArg){
  optionalArg = myFunc.arguments.length<2 ? 'defaultValue' : optionalArg;

  ...

-- doing so, it can't possibly fail, but I don't know if your way has any chance of failing, just now I can't think up a scenario, where it actually would fail ...

And then Paul provided one failing scenario !-)

In my case it doesn't work, even with __DIR__ or getcwd() it keeps picking the wrong path, I solved by defining a costant in every file I need with the absolute base path of the project:

if(!defined('THISBASEPATH')){ define('THISBASEPATH', '/mypath/'); }
require_once THISBASEPATH.'cache/crud.php';
/*every other require_once you need*/

I have MAMP with php 5.4.10 and my folder hierarchy is basilar:

q.php 
w.php 
e.php 
r.php 
cache/a.php 
cache/b.php 
setting/a.php 
setting/b.php

....

I had a same problem because I installed both of python2.7 and python3. when I run program with python3 I received same error. I install scipy with this command and problem has been solved:

sudo apt-get install python3-scipy

it is just a sample to avoid max recursion error. we have to use option (maxrecursion 365); or option (maxrecursion 0);

DECLARE @STARTDATE datetime; 
DECLARE @EntDt datetime; 
set @STARTDATE = '01/01/2009';  
set @EntDt = '12/31/2009'; 
declare @dcnt int; 
;with DateList as   
 (   
    select @STARTDATE DateValue   
    union all   
    select DateValue + 1 from    DateList      
    where   DateValue + 1 < convert(VARCHAR(15),@EntDt,101)   
 )   
  select count(*) as DayCnt from (   
  select DateValue,DATENAME(WEEKDAY, DateValue ) as WEEKDAY from DateList
  where DATENAME(WEEKDAY, DateValue ) not IN ( 'Saturday','Sunday' )     
  )a
option (maxrecursion 365);

Just FYI there are 3 other answers given to this question that use Guava, but none answer the question. The asker has said he wishes to find all Cats with a matching property, e.g. age of 3. Iterables.find will only match one, if any exist. You would need to use Iterables.filter to achieve this if using Guava, for example:

Iterable<Cat> matches = Iterables.filter(cats, new Predicate<Cat>() {
    @Override
    public boolean apply(Cat input) {
        return input.getAge() == 3;
    }
});

    alert(myClass + " " + myId);_x000D_

This works for me. There is no event.target.class function in jQuery.

The idea I generally use when working with transactions looks like this (semi-pseudo-code):

try {
    // First of all, let's begin a transaction
    $db->beginTransaction();
    
    // A set of queries; if one fails, an exception should be thrown
    $db->query('first query');
    $db->query('second query');
    $db->query('third query');
    
    // If we arrive here, it means that no exception was thrown
    // i.e. no query has failed, and we can commit the transaction
    $db->commit();
} catch (\Throwable $e) {
    // An exception has been thrown
    // We must rollback the transaction
    $db->rollback();
    throw $e; // but the error must be handled anyway
}

• PDO can do that, depending on how you configure it
  • See PDO::setAttribute
  • and PDO::ATTR_ERRMODE and PDO::ERRMODE_EXCEPTION
• else, with some other API, you might have to test the result of the function used to execute a query, and throw an exception yourself.

For example, quite often you'll have a couple of queries before the transaction (before the begin) and another couple of queries after the transaction (after either commit or rollback) and you'll want those queries executed no matter what happened (or not) in the transaction.

Since you are using jQuery you can use this onClick handler which calls click:

$("#datepicker").click()

This is the same as $("#datepicker").trigger("click").

For a jQuery-free version check out this answer on SO.

Update:

This answer is outdated, since after all this question is more than 8 years old. Today all up to date browsers support rgba, box shadows and so on. But this is a decent example how it was 8+ years ago.

Create a constructor of FeedAdapter :

Context context; //global
public FeedAdapter(Context context)
{
   this.context = context;  
}

and in Activity

FeedAdapter obj = new FeedAdapter(this);

?? Indian rupee sign. HTML: ₹ — ₹ or ₹ — also ₹, corresponding to Unicode U+20B9.

Before the end of your code, insert this line:

system("pause");

This will keep the console until you hit a key.

#include <iostream>
#include <string>

using namespace std;

int main()
{
    string s;
    cout << "Please enter your first name followed by a newline\n";
    cin >> s;
    cout << "Hello, " << s << '\n';
    system("pause"); // <----------------------------------
    return 0; // This return statement isn't necessary
}

UILabel has a property lineBreakMode that you can set as per your requirement.

Real, User and Sys process time statistics

One of these things is not like the other. Real refers to actual elapsed time; User and Sys refer to CPU time used only by the process.

• Real is wall clock time - time from start to finish of the call. This is all elapsed time including time slices used by other processes and time the process spends blocked (for example if it is waiting for I/O to complete).

• User is the amount of CPU time spent in user-mode code (outside the kernel) within the process. This is only actual CPU time used in executing the process. Other processes and time the process spends blocked do not count towards this figure.

• Sys is the amount of CPU time spent in the kernel within the process. This means executing CPU time spent in system calls within the kernel, as opposed to library code, which is still running in user-space. Like 'user', this is only CPU time used by the process. See below for a brief description of kernel mode (also known as 'supervisor' mode) and the system call mechanism.

User+Sys will tell you how much actual CPU time your process used. Note that this is across all CPUs, so if the process has multiple threads (and this process is running on a computer with more than one processor) it could potentially exceed the wall clock time reported by Real (which usually occurs). Note that in the output these figures include the User and Sys time of all child processes (and their descendants) as well when they could have been collected, e.g. by wait(2) or waitpid(2), although the underlying system calls return the statistics for the process and its children separately.

Origins of the statistics reported by time (1)

The statistics reported by time are gathered from various system calls. 'User' and 'Sys' come from wait (2) (POSIX) or times (2) (POSIX), depending on the particular system. 'Real' is calculated from a start and end time gathered from the gettimeofday (2) call. Depending on the version of the system, various other statistics such as the number of context switches may also be gathered by time.

On a multi-processor machine, a multi-threaded process or a process forking children could have an elapsed time smaller than the total CPU time - as different threads or processes may run in parallel. Also, the time statistics reported come from different origins, so times recorded for very short running tasks may be subject to rounding errors, as the example given by the original poster shows.

A brief primer on Kernel vs. User mode

On Unix, or any protected-memory operating system, 'Kernel' or 'Supervisor' mode refers to a privileged mode that the CPU can operate in. Certain privileged actions that could affect security or stability can only be done when the CPU is operating in this mode; these actions are not available to application code. An example of such an action might be manipulation of the MMU to gain access to the address space of another process. Normally, user-mode code cannot do this (with good reason), although it can request shared memory from the kernel, which could be read or written by more than one process. In this case, the shared memory is explicitly requested from the kernel through a secure mechanism and both processes have to explicitly attach to it in order to use it.

The privileged mode is usually referred to as 'kernel' mode because the kernel is executed by the CPU running in this mode. In order to switch to kernel mode you have to issue a specific instruction (often called a trap) that switches the CPU to running in kernel mode and runs code from a specific location held in a jump table. For security reasons, you cannot switch to kernel mode and execute arbitrary code - the traps are managed through a table of addresses that cannot be written to unless the CPU is running in supervisor mode. You trap with an explicit trap number and the address is looked up in the jump table; the kernel has a finite number of controlled entry points.

The 'system' calls in the C library (particularly those described in Section 2 of the man pages) have a user-mode component, which is what you actually call from your C program. Behind the scenes, they may issue one or more system calls to the kernel to do specific services such as I/O, but they still also have code running in user-mode. It is also quite possible to directly issue a trap to kernel mode from any user space code if desired, although you may need to write a snippet of assembly language to set up the registers correctly for the call.

More about 'sys'

There are things that your code cannot do from user mode - things like allocating memory or accessing hardware (HDD, network, etc.). These are under the supervision of the kernel, and it alone can do them. Some operations like malloc orfread/fwrite will invoke these kernel functions and that then will count as 'sys' time. Unfortunately it's not as simple as "every call to malloc will be counted in 'sys' time". The call to malloc will do some processing of its own (still counted in 'user' time) and then somewhere along the way it may call the function in kernel (counted in 'sys' time). After returning from the kernel call, there will be some more time in 'user' and then malloc will return to your code. As for when the switch happens, and how much of it is spent in kernel mode... you cannot say. It depends on the implementation of the library. Also, other seemingly innocent functions might also use malloc and the like in the background, which will again have some time in 'sys' then.

I consider the following to be more pragmatic since it does not sequence the ajax calls but that is surely a matter of taste.

function check_ajax_call_count()
{
    if ( window.ajax_call_count==window.ajax_calls_completed )
    {
        // do whatever needs to be done after the last ajax call finished
    }
}
window.ajax_call_count = 0;
window.ajax_calls_completed = 10;
setInterval(check_ajax_call_count,100);

Now you can iterate window.ajax_call_count inside the success part of your ajax requests until it reaches the specified number of calls send (window.ajax_calls_completed).

I Solved this problem adding @Cascade to the @ManyToOne attribute.

This one doesn't break the exposed API.

from argparse import ArgumentParser, SUPPRESS
# Disable default help
parser = ArgumentParser(add_help=False)
required = parser.add_argument_group('required arguments')
optional = parser.add_argument_group('optional arguments')

# Add back help 
optional.add_argument(
    '-h',
    '--help',
    action='help',
    default=SUPPRESS,
    help='show this help message and exit'
)
required.add_argument('--required_arg', required=True)
optional.add_argument('--optional_arg')

Which will show the same as above and should survive future versions:

usage: main.py [-h] [--required_arg REQUIRED_ARG]
           [--optional_arg OPTIONAL_ARG]

required arguments:
  --required_arg REQUIRED_ARG

optional arguments:
  -h, --help                    show this help message and exit
  --optional_arg OPTIONAL_ARG

Here is a generic way to loop through the field objects in an object (person):

for (var property in person) {
    console.log(property,":",person[property]);
}

The person obj looks like this:

var person={
    first_name:"johnny",
    last_name: "johnson",
    phone:"703-3424-1111"
};

It appears that the use of SAPPLY on a data.frame to convert variables to factors at once does not work as it produces a matrix/ array. My approach is to use LAPPLY instead, as follows.

## let us create a data.frame here

class <- c("7", "6", "5", "3")

cash <- c(100, 200, 300, 150)

height <- c(170, 180, 150, 165)

people <- data.frame(class, cash, height)

class(people) ## This is a dataframe 

## We now apply lapply to the data.frame as follows.

bb <- lapply(people, as.factor) %>% data.frame() 

## The lapply part returns a list which we coerce back to a data.frame

class(bb) ## A data.frame

##Now let us check the classes of the variables 

class(bb$class)

class(bb$height)

class(bb$cash) ## as expected, are all factors. 

$http.delete method doesn't accept request body. You can try this workaround :

$http( angular.merge({}, config || {}, {
    method  : 'delete',
    url     : _url,
    data    : _data
}));

where in config you can pass config data like headers etc.

as i also wanted that same thing in a project u can do something like

HTML

<div class="col-md-6"></div>
<div class="divider-vertical"></div>
<div class="col-md-5"></div>

CSS

.divider-vertical {
    height: 100px;                   /* any height */
    border-left: 1px solid gray;     /* right or left is the same */
    float: left;                     /* so BS grid doesn't break */
    opacity: 0.5;                    /* optional */
    margin: 0 15px;                  /* optional */
}

LESS

.divider-vertical(@h:100, @opa:1, @mar:15) {
    height: unit(@h,px);             /* change it to rem,em,etc.. */
    border-left: 1px solid gray;
    float: left;
    opacity: @opa;
    margin: 0 unit(@mar,px);         /* change it to rem,em,etc.. */
}

Another way is with Arrays.setAll, or Arrays.fill:

String[] v = new String[1000];
Arrays.setAll(v, i -> Integer.toString(i * 30));
//v => ["0", "30", "60", "90"... ]

Arrays.fill(v, "initial value");
//v => ["initial value", "initial value"... ]

This is more usefull for initializing (possibly large) arrays where you can compute each element from its index.

In C# one easy way is to mark the ones you wish to delete then create a new list to iterate over...

foreach(var item in list.ToList()){if(item.Delete) list.Remove(item);}  

or even simpler use linq....

list.RemoveAll(p=>p.Delete);

but it is worth considering if other tasks or threads will have access to the same list at the same time you are busy removing, and maybe use a ConcurrentList instead.

I had same problem. I need show url for a search engine

I use two routes like this

Route::get('buscar/{nom}', 'FrontController@buscarPrd');

Route::post('buscar', function(){

   $bsqd = Input::get('nom');    

   return Redirect::action('FrontController@buscarPrd', array('nom'=>$bsqd));

});

First one used to show url like we want

Second one used by form and redirect to first one

You can overload the main() method, but only public static void main(String[] args) will be used when your class is launched by the JVM. For example:

public class Test {
    public static void main(String[] args) {
        System.out.println("main(String[] args)");
    }

    public static void main(String arg1) {
        System.out.println("main(String arg1)");
    }

    public static void main(String arg1, String arg2) {
        System.out.println("main(String arg1, String arg2)");
    }
}

That will always print main(String[] args) when you run java Test ... from the command line, even if you specify one or two command-line arguments.

You can call the main() method yourself from code, of course - at which point the normal overloading rules will be applied.

EDIT: Note that you can use a varargs signature, as that's equivalent from a JVM standpoint:

public static void main(String... args)

On WorkBench I resolved it By deactivating the safe update mode:

-Edit -> Preferences -> Sql Editor then uncheck Safe update.

Thought someone might like explanation by (annotated) example:

Below, if my deepClone() function does its job right, the test (as described in the 'it()' call) will succeed:

describe('deepClone() array copy', ()=>{
    let source:any = {}
    let clone:any = source
    beforeAll(()=>{
        source.a = [1,'string literal',{x:10, obj:{y:4}}]
        clone = Utils.deepClone(source) // THE CLONING ACT TO BE TESTED - lets see it it does it right.
    })
    it('should create a clone which has unique identity, but equal values as the source object',()=>{
        expect(source !== clone).toBe(true) // If we have different object instances...
        expect(source).not.toBe(clone) // <= synonymous to the above. Will fail if: you remove the '.not', and if: the two being compared are indeed different objects.
        expect(source).toEqual(clone) // ...that hold same values, all tests will succeed.
    })
})

Of course this is not a complete test suite for my deepClone(), as I haven't tested here if the object literal in the array (and the one nested therein) also have distinct identity but same values.

Try this regex:

/^[\w&.-]+$/

Also you can use test.

if ( pattern.test( qry ) ) {
  // valid
}

The easiest way to do this now is with a flexbox:

http://css-tricks.com/snippets/css/a-guide-to-flexbox/

The CSS is then simply:

#container {
    display: flex;
    justify-content: space-between;
}

demo: http://jsfiddle.net/QPrk3/

However, this is currently only supported by relatively recent browsers (http://caniuse.com/flexbox). Also, the spec for flexbox layout has changed a few times, so it's possible to cover more browsers by additionally including an older syntax:

http://css-tricks.com/old-flexbox-and-new-flexbox/

http://css-tricks.com/using-flexbox/

                   contentType: "application/json; charset=utf-8",
                   beforeSend: function(x) {
        if(x && x.overrideMimeType) {

        }
    },

                    alert(response.subjectname);
                    $('#course').html("<option>"+response.coursename+"</option>"); 
                    $('#subject').html("<option>"+response.subjectname+"</option>");

                  },
                  error: function( error,x,y)
                  {

                  alert( x,y );

              }
                   });

The reliable only way to protect code is to run it on a server you control and provide your clients with a client which interfaces with that server.

I found a solution thanks to Ben Alpert on discuss.reactjs.org. The suggested approach attaches a handler to the document but that turned out to be problematic. Clicking on one of the components in my tree resulted in a rerender which removed the clicked element on update. Because the rerender from React happens before the document body handler is called, the element was not detected as "inside" the tree.

The solution to this was to add the handler on the application root element.

main:

window.__myapp_container = document.getElementById('app')
React.render(<App/>, window.__myapp_container)

component:

import { Component, PropTypes } from 'react';
import ReactDOM from 'react-dom';

export default class ClickListener extends Component {

  static propTypes = {
    children: PropTypes.node.isRequired,
    onClickOutside: PropTypes.func.isRequired
  }

  componentDidMount () {
    window.__myapp_container.addEventListener('click', this.handleDocumentClick)
  }

  componentWillUnmount () {
    window.__myapp_container.removeEventListener('click', this.handleDocumentClick)
  }

  /* using fat arrow to bind to instance */
  handleDocumentClick = (evt) => {
    const area = ReactDOM.findDOMNode(this.refs.area);

    if (!area.contains(evt.target)) {
      this.props.onClickOutside(evt)
    }
  }

  render () {
    return (
      <div ref='area'>
       {this.props.children}
      </div>
    )
  }
}

I know this thread is old now, but here is some decent documentation on Google Docs API. It was ridiculously hard to find, but useful, so maybe it will help you some. http://pythonhosted.org/gdata/docs/api.html.

I used gspread recently for a project to graph employee time data. I don't know how much it might help you, but here's a link to the code: https://github.com/lightcastle/employee-timecards

Gspread made things pretty easy for me. I was also able to add logic in to check for various conditions to create month-to-date and year-to-date results. But I just imported the whole dang spreadsheet and parsed it from there, so I'm not 100% sure that it is exactly what you're looking for. Best of luck.

The "Accepted" Answer is Incorrect and Incomplete

The only answers that are accurate are the @jive-dadson and @EddingtonsMonkey answers, and in support @nils-pipenbrinck. The other answers (including the accepted) are linking to or citing sources that are either wrong, irrelevant, obsolete, or broken.

Briefly:

• sRGB must be LINEARIZED before applying the coefficients.
• Luminance (L or Y) is linear as is light.
• Perceived lightness (L*) is nonlinear as is human perception.
• HSV and HSL are not even remotely accurate in terms of perception.
• The IEC standard for sRGB specifies a threshold of 0.04045 it is NOT 0.03928 (that was from an obsolete early draft).
• The be useful (i.e. relative to perception), Euclidian distances require a perceptually uniform Cartesian vector space such as CIELAB. sRGB is not one.

What follows is a correct and complete answer:

Because this thread appears highly in search engines, I am adding this answer to clarify the various misconceptions on the subject.

Luminance is a linear measure of light, spectrally weighted for normal vision but not adjusted for the non-linear perception of lightness. It can be a relative measure, Y as in CIEXYZ, or as L, an absolute measure in cd/m² (not to be confused with L*).

Perceived lightness is used by some vision models such as CIELAB, here L* (Lstar) is a value of perceptual lightness, and is non-linear to approximate the human vision non-linear response curve.

Brightness is a perceptual attribute, it does not have a "physical" measure. However some color appearance models do have a value, usualy denoted as "Q" for perceived brightness, which is different than perceived lightness.

Luma (Y´ prime) is a gamma encoded, weighted signal used in some video encodings (Y´I´Q´). It is not to be confused with linear luminance.

Gamma or transfer curve (TRC) is a curve that is often similar to the perceptual curve, and is commonly applied to image data for storage or broadcast to reduce perceived noise and/or improve data utilization (and related reasons).

To determine perceived lightness, first convert gamma encoded R´G´B´ image values to linear luminance (L or Y ) and then to non-linear perceived lightness (L*)

TO FIND LUMINANCE:

...Because apparently it was lost somewhere...

Step One:

Convert all sRGB 8 bit integer values to decimal 0.0-1.0

  vR = sR / 255;
  vG = sG / 255;
  vB = sB / 255;

Step Two:

Convert a gamma encoded RGB to a linear value. sRGB (computer standard) for instance requires a power curve of approximately V^2.2, though the "accurate" transform is:

Where V´ is the gamma-encoded R, G, or B channel of sRGB.
Pseudocode:

function sRGBtoLin(colorChannel) {
        // Send this function a decimal sRGB gamma encoded color value
        // between 0.0 and 1.0, and it returns a linearized value.

    if ( colorChannel <= 0.04045 ) {
            return colorChannel / 12.92;
        } else {
            return pow((( colorChannel + 0.055)/1.055),2.4));
        }
    }

Step Three:

To find Luminance (Y) apply the standard coefficients for sRGB:

Pseudocode using above functions:

Y = (0.2126 * sRGBtoLin(vR) + 0.7152 * sRGBtoLin(vG) + 0.0722 * sRGBtoLin(vB))

TO FIND PERCEIVED LIGHTNESS:

Step Four:

Take luminance Y from above, and transform to L*

Pseudocode:

function YtoLstar(Y) {
        // Send this function a luminance value between 0.0 and 1.0,
        // and it returns L* which is "perceptual lightness"

    if ( Y <= (216/24389) {       // The CIE standard states 0.008856 but 216/24389 is the intent for 0.008856451679036
            return Y * (24389/27);  // The CIE standard states 903.3, but 24389/27 is the intent, making 903.296296296296296
        } else {
            return pow(Y,(1/3)) * 116 - 16;
        }
    }

L* is a value from 0 (black) to 100 (white) where 50 is the perceptual "middle grey". L* = 50 is the equivalent of Y = 18.4, or in other words an 18% grey card, representing the middle of a photographic exposure (Ansel Adams zone V).

Since I had to do something like this, here's my solution given a generator and a batch size:

def pop_n_elems_from_generator(g, n):
    elems = []
    try:
        for idx in xrange(0, n):
            elems.append(g.next())
        return elems
    except StopIteration:
        return elems

Hell, of course yes, with several limitations.

Android is a kinda special Linux distribution, with no usual suff like X11, and you can't install Apache2 with apt-get. But if you have ARM cross-compiler, you can copy your ELF files to the device, and run it from a terminal app or if you have installed some SSHD app, you can even use SSH from your desktop/notebook to access the Android device.

To copy and launch a native Linux executable, you have not root your device. That's the point, where I am, I've compiled my own tiny webserver to Android (and also for webOS), it runs, hallelujah.

There comes the issues, which I can't answer:

1. My tiny webserver use only stdlib and pthreads. I have no idea how to use the (native Linux) libraries comes with Android, there are useful ones, altough, I can live without them.

2. Now I can launch my app from a terminal app by hand. But I don't know, what's the best way of deploying such native apps to Android. I think I should be write a small Android app, which launches the server and not letting automatically stopped by the system (say, as like music players never killed). Also, if its a service, it should somehow started on boot. I'm not familiar with Android.

You 100% can do this on the server side...

.img-responsive is the right way to make images responsive with bootstrap 3 You can add some height rule for the picture you want to make responsive, because with responsibility, width changes along the height, fix it and there you are.

[0-9] is not always equivalent to \d. In python3, [0-9] matches only 0123456789 characters, while \d matches [0-9] and other digit characters, for example Eastern Arabic numerals ??????????.

This usually happens when debugging using the emulator, which is known to be slow anyway.

Splitting a string by whitespace is very simple:

print $_, "\n" for split ' ', 'file1.gz file1.gz file3.gz';

This is a special form of split actually (as this function usually takes patterns instead of strings):

As another special case, split emulates the default behavior of the command line tool awk when the PATTERN is either omitted or a literal string composed of a single space character (such as ' ' or "\x20"). In this case, any leading whitespace in EXPR is removed before splitting occurs, and the PATTERN is instead treated as if it were /\s+/; in particular, this means that any contiguous whitespace (not just a single space character) is used as a separator.

Here's an answer for the original question (with a simple string without any whitespace):

Perhaps you want to split on .gz extension:

my $line = "file1.gzfile1.gzfile3.gz";
my @abc = split /(?<=\.gz)/, $line;
print $_, "\n" for @abc;

Here I used (?<=...) construct, which is look-behind assertion, basically making split at each point in the line preceded by .gz substring.

If you work with the fixed set of extensions, you can extend the pattern to include them all:

my $line = "file1.gzfile2.txtfile2.gzfile3.xls";
my @exts = ('txt', 'xls', 'gz');
my $patt = join '|', map { '(?<=\.' . $_ . ')' } @exts;
my @abc = split /$patt/, $line;
print $_, "\n" for @abc;

Amazon provides a policy generator tool:

https://awspolicygen.s3.amazonaws.com/policygen.html

After that, you can enter the policy requirements for the bucket on the AWS console:

https://console.aws.amazon.com/s3/home

Following is the solution which I came up with if there are multiple characters in the string all having the highest frequency.

mystr = input("enter string: ")
#define dictionary to store characters and their frequencies
mydict = {}
#get the unique characters
unique_chars = sorted(set(mystr),key = mystr.index)
#store the characters and their respective frequencies in the dictionary
for c in unique_chars:
    ctr = 0
    for d in mystr:
        if d != " " and d == c:
            ctr = ctr + 1
    mydict[c] = ctr
print(mydict)
#store the maximum frequency
max_freq = max(mydict.values())
print("the highest frequency of occurence: ",max_freq)
#print all characters with highest frequency
print("the characters are:")
for k,v in mydict.items():
    if v == max_freq:
        print(k)

Input: "hello people"

Output:

{'o': 2, 'p': 2, 'h': 1, ' ': 0, 'e': 3, 'l': 3}

the highest frequency of occurence: 3

the characters are:

e

l

How to differentiate between single clicks and double clicks on one and the same element?

If you don't need to mix them, you can rely on click and dblclick and each will do the job just fine.

A problem arises when trying to mix them: a dblclick event will actually trigger a click event as well, so you need to determine whether a single click is a "stand-alone" single click, or part of a double click.

In addition: you shouldn't use both click and dblclick on one and the same element:

It is inadvisable to bind handlers to both the click and dblclick events for the same element. The sequence of events triggered varies from browser to browser, with some receiving two click events before the dblclick and others only one. Double-click sensitivity (maximum time between clicks that is detected as a double click) can vary by operating system and browser, and is often user-configurable.
Source: https://api.jquery.com/dblclick/

Now on to the good news:

You can use the event's detail property to detect the number of clicks related to the event. This makes double clicks inside of click fairly easy to detect.

The problem remains of detecting single clicks and whether or not they're part of a double click. For that, we're back to using a timer and setTimeout.

Wrapping it all together, with use of a data attribute (to avoid a global variable) and without the need to count clicks ourselves, we get:

HTML:

<div class="clickit" style="font-size: 200%; margin: 2em; padding: 0.25em; background: orange;">Double click me</div>

<div id="log" style="background: #efefef;"></div>

JavaScript:

<script>
var clickTimeoutID;
$( document ).ready(function() {

    $( '.clickit' ).click( function( event ) {

        if ( event.originalEvent.detail === 1 ) {
            $( '#log' ).append( '(Event:) Single click event received.<br>' );

            /** Is this a true single click or it it a single click that's part of a double click?
             * The only way to find out is to wait it for either a specific amount of time or the `dblclick` event.
             **/
            clickTimeoutID = window.setTimeout(
                    function() {
                        $( '#log' ).append( 'USER BEHAVIOR: Single click detected.<br><br>' );
                    },
                    500 // how much time users have to perform the second click in a double click -- see accessibility note below.
                );

        } else if ( event.originalEvent.detail === 2 ) {
            $( '#log' ).append( '(Event:) Double click event received.<br>' );
            $( '#log' ).append( 'USER BEHAVIOR: Double click detected.<br>' );
            window.clearTimeout( clickTimeoutID ); // it's a dblclick, so cancel the single click behavior.
        } // triple, quadruple, etc. clicks are ignored.

    });

});
</script>

JSfiddle

Notes about accessibility and double click speeds:

• As Wikipedia puts it "The maximum delay required for two consecutive clicks to be interpreted as a double-click is not standardized."
• No way of detecting the system's double-click speed in the browser.
• Seems the default is 500 ms and the range 100-900mms on Windows (source)
• Think of people with disabilities who set, in their OS settings, the double click speed to its slowest.
  • If the system double click speed is slower than our default 500 ms above, both the single- and double-click behaviors will be triggered.
  • Either don't use rely on combined single and double click on one and the same item.
  • Or: add a setting in the options to have the ability to increase the value.

It took a while to find a satisfying solution, I hope this helps!

I didn't want to delete all the packages in vendor/ directory, so here is how I did it:

1. rm -rf vendor/package-i-messed-up
2. composer install again

BindingResult is used for validation..

Example:-

 public @ResponseBody String nutzer(@ModelAttribute(value="nutzer") Nutzer nutzer, BindingResult ergebnis){
        String ergebnisText;
        if(!ergebnis.hasErrors()){
            nutzerList.add(nutzer);
            ergebnisText = "Anzahl: " + nutzerList.size();
        }else{
            ergebnisText = "Error!!!!!!!!!!!";
        }
        return ergebnisText;
    }

What if you have your data in CSV format and convert it to HTML for display on the web page? You may use the http://code.google.com/p/js-tables/ plugin. Check this example http://code.google.com/p/js-tables/wiki/Table As you are already using jQuery library I have assumed you are able to add other javascript toolkit libraries.

If the data is in CSV format, you should be able to use the generic 'application/octetstream' mime type. All the 3 mime types you have tried are dependent on the software installed on the clients computer.

Here is what I would do.

1. In your base class (can be rootVC BaseVc etc),

   A. Write a Protocol to send the "DidFinishReloading" callback.

   @protocol ReloadComplition <NSObject>
   @required
   - (void)didEndReloading:(UITableView *)tableView;
   @end
   

   B. Write a generic method to reload the table view.

   -(void)reloadTableView:(UITableView *)tableView withOwner:(UIViewController *)aViewController;
   

2. In the base class method implementation, call reloadData followed by delegateMethod with delay.

   -(void)reloadTableView:(UITableView *)tableView withOwner:(UIViewController *)aViewController{
       [[NSOperationQueue mainQueue] addOperationWithBlock:^{
           [tableView reloadData];
           if(aViewController && [aViewController respondsToSelector:@selector(didEndReloading:)]){
               [aViewController performSelector:@selector(didEndReloading:) withObject:tableView afterDelay:0];
           }
       }];
   }
   

3. Confirm to the reload completion protocol in all the view controllers where you need the callback.

   -(void)didEndReloading:(UITableView *)tableView{
       //do your stuff.
   }

I know that the question has been answered, but I hope my solution helps other people.

stopPropagation caused problems in my case, because I needed the click event for something else. Moreover, not every element should cause the div to be closed when clicked.

My solution:

$(document).click(function(e) {
    if (($(e.target).closest("#mydiv").attr("id") != "mydiv") &&
        $(e.target).closest("#div-exception").attr("id") != "div-exception") {
        alert("Clicked outside!");
    }
});

I looked at Nate Barr's answer above, which you seemed to like. It doesn't seem very different from the simpler

html {background-color: grey}

For most sites you have HTML pages that you visit when you use your browser. These are human-readable pages (once rendered in your browser) where a lot of data might be crammed together, because it makes sense for humans.

Now imagine that someone else want to use some of that data. They could download your page and start filtering out all the "noise" to get the data they wanted, but most websites are not built in a way where data is 100% certain to be placed in the same spot for all elements, so in addition to being cumbersome it also becomes unreliable.

Enter web services.

A web service is something that a website chooses to offer to those who wish to read, update and/or delete data from your website. You might call it a "backdoor" to your data. Instead of presenting the data as part of a webpage it is provided in a pre-determined way where some of the more popular are XML and JSON. There are several ways to communicate with a webservice, some use SOAP, others have REST'ful web services, etc.

What is common for all web services is that they are the machine-readable equivelant to the webpages the site otherwise offers. This means that others who wish to use the data can send a request to get certain data back that is easy to parse and use. Some sites may require you to provide a username/password in the request, for sensitive data, while other sites allow anyone to extract whatever data they might need.

maybe you should try installing VC++ runtime as explained here.

There's a fairly good chance you're missing the correct VC++ runtime for the version of PHP you're running.

If you're running PHP 5.5.x you need to ensure the VC++11 runtime is installed:

http://www.microsoft.com/en-us/download/details.aspx?id=30679

Make sure you download and install the x86 version (vcredist_x86.exe), PHP on Windows isn't 64 bit yet.

If you're running PHP 5.4.x then you need to install the VC++9 runtime:

http://www.microsoft.com/en-us/download/details.aspx?id=5582

myLabel.setHorizontalAlignment(SwingConstants.CENTER);
myLabel.setVerticalAlignment(SwingConstants.CENTER);

If you cannot reconstruct the label for some reason, this is how you edit these properties of a pre-existent JLabel.

I wanted to share how you can use this to change a attribute of the button, because it took me some time to figure it out...

You can use the git+ssh URI scheme, but you must set a username. Notice the git@ part in the URI:

pip install git+ssh://[email protected]/echweb/echweb-utils.git

Also read about deploy keys.

PS: In my installation, the "git+ssh" URI scheme works only with "editable" requirements:

pip install -e URI#egg=EggName

Remember: Change the : character that git remote -v prints to a / character before using the remote's address in the pip command:

$ git remote -v
origin  [email protected]:echweb/echweb-utils.git (fetch)
#                     ^ change this to a '/' character

If you forget, you will get this error:

ssh: Could not resolve hostname github.com:echweb:
         nodename nor servname provided, or not known

This one get everything between the "." characters. Please note this won't work for more complex URLs like "www.somesite.co.uk" Ideally the function would check for how many instances of the "." character and choose the substring accordingly.

CREATE FUNCTION dbo.GetURL (@URL VARCHAR(250))
RETURNS VARCHAR(250)
AS BEGIN
    DECLARE @Work VARCHAR(250)

    SET @Work = @URL

    SET @Work = SUBSTRING(@work, CHARINDEX('.', @work) + 1, LEN(@work))   
    SET @Work = SUBSTRING(@work, 0, CHARINDEX('.', @work))

    --Alternate:
    --SET @Work = SUBSTRING(@work, CHARINDEX('.', @work) + 1, CHARINDEX('.', @work) + 1)   

    RETURN @work
END

All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)

Based on this related answer, you are looking at a list that looks like: A-Z, a-z, 0-9, -, ., _, ~, :, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, %, and =. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. % can only be used in conjunction with url encoding as in %20), the RFC has all of these specifics.

Small Note for Windows 8 user, Intel HAX will not work if Hyper-V feature is enable. Hyper-V (like most of the virtualization tech) will exclusively lock the VT extension witch will prevent HAX to work properly. A workaround if you “need” Hyper-V too might be to stop manually the Hyper-V services when you need HAX (haven’t tested it yet through).

Beside the quite obvious reason (IIS), there is another reason that is common enough for this problem. It is worth to quote this question and its answer here:

http://stackoverflow.com/questions/22994888/why-skype-using-http-or-https-ports-80-and-443 

So, if you have Skype installed in the computer, be sure to check this as well. The solution is quoted here:

To turn off and disable Skype usage of and listening on port 80 and port 443, open the Skype window, then click on Tools menu and select Options. Click on Advanced tab, and go to Connection sub-tab. Untick or uncheck the check box for Use port 80 and 443 as an alternatives for incoming connections option. Click on Save button and then restart Skype to make the change effective.

You can use this function

var datastring = $("#contactForm").serialize();
$.ajax({
    type: "POST",
    url: "your url.php",
    data: datastring,
    dataType: "json",
    success: function(data) {
        //var obj = jQuery.parseJSON(data); if the dataType is not specified as json uncomment this
        // do what ever you want with the server response
    },
    error: function() {
        alert('error handling here');
    }
});

return type is json

EDIT: I use event.preventDefault to prevent the browser getting submitted in such scenarios.

Adding more data to the answer.

dataType: "jsonp" if it is a cross-domain call.

beforeSend: // this is a pre-request call back function

complete: // a function to be called after the request ends.so code that has to be executed regardless of success or error can go here

async: // by default, all requests are sent asynchronously

cache: // by default true. If set to false, it will force requested pages not to be cached by the browser.

I often use row_number() as a quick way to discard duplicate records from my select statements. Just add a where clause. Something like...

select a,b,rn 
  from (select a, b, row_number() over (partition by a,b order by a,b) as rn           
          from table) 
 where rn=1;

With Application Loader now gone from Xcode I had a look around to see how to upload an .ipa file, since I use UE4 and I don't touch Xcode at all during development. Turns out it's pretty hidden away, You need to go to Window, Organiser, Archives. The archive will only appear if you ticked the "Generate Xcode Archive Package" tickbox in Project Settings. Then you just click Distribute and it's just does it.

I finally found a solution on Windows, to have a real silent and automatic install:

On Windows, the following syntax doesn't work:

echo y | sdkmanager --licenses

It seems the "y" aren't correctly sent to the java program called in the batch.

The workaround is to create a file file-y.txt with several "y", one by line, and to use

call sdkmanager --licenses < file-y.txt

This will create the needed files in the licenses directory. The problem is probably related to the use of BufferedReader in Java

The spirit of handlebars is that it is "logicless". Sometimes this makes us feel like we are fighting with it, and sometimes we end up with ugly nested if/else logic. You could write a helper; many people augment handlebars with a "better" conditional operator or believe that it should be part of the core. I think, though, that instead of this,

{{#if FriendStatus.IsFriend}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div>
{{else}}
  {{#if FriendStatus.FriendRequested}}
    <div class="ui-state-default ui-corner-all" title=".ui-icon-check"><span class="ui-icon ui-icon-check"></span></div>
  {{else}}
    <div class="ui-state-default ui-corner-all" title=".ui-icon-plusthick"><span class="ui-icon ui-icon-plusthick"></span></div>
  {{/if}}
{{/if}}

you might want to arrange things in your model so that you can have this,

{{#if is_friend }}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div>
{{/if}}

{{#if is_not_friend_yet }}
    <div class="ui-state-default ui-corner-all" title=".ui-icon-check"><span class="ui-icon ui-icon-check"></span></div>
{{/if}}

{{#if will_never_be_my_friend }}
    <div class="ui-state-default ui-corner-all" title=".ui-icon-plusthick"><span class="ui-icon ui-icon-plusthick"></span></div>
{{/if}}

Just make sure that only one of these flags is ever true. Chances are, if you are using this if/elsif/else in your view, you are probably using it somewhere else too, so these variables might not end up being superfluous.

Keep it lean.

It's also helpful to remember that it's pretty easy to play with queries with the sqlite command line utility:

EDIT:

Since 1.10, strings.Builder exists. Example:

buf := new(strings.Builder)
n, err := io.Copy(buf, r)
// check errors
fmt.Println(buf.String())

OUTDATED INFORMATION BELOW

The short answer is that it it will not be efficient because converting to a string requires doing a complete copy of the byte array. Here is the proper (non-efficient) way to do what you want:

buf := new(bytes.Buffer)
buf.ReadFrom(yourReader)
s := buf.String() // Does a complete copy of the bytes in the buffer.

This copy is done as a protection mechanism. Strings are immutable. If you could convert a []byte to a string, you could change the contents of the string. However, go allows you to disable the type safety mechanisms using the unsafe package. Use the unsafe package at your own risk. Hopefully the name alone is a good enough warning. Here is how I would do it using unsafe:

buf := new(bytes.Buffer)
buf.ReadFrom(yourReader)
b := buf.Bytes()
s := *(*string)(unsafe.Pointer(&b))

There we go, you have now efficiently converted your byte array to a string. Really, all this does is trick the type system into calling it a string. There are a couple caveats to this method:

1. There are no guarantees this will work in all go compilers. While this works with the plan-9 gc compiler, it relies on "implementation details" not mentioned in the official spec. You can not even guarantee that this will work on all architectures or not be changed in gc. In other words, this is a bad idea.
2. That string is mutable! If you make any calls on that buffer it will change the string. Be very careful.

My advice is to stick to the official method. Doing a copy is not that expensive and it is not worth the evils of unsafe. If the string is too large to do a copy, you should not be making it into a string.

Although this is an "old" thread, I still would like to add the following to it:

I've experienced the next case:

• In the header file of a class, I had

int SetI2cSlaveAddress( UCHAR addr, bool force );

• In the source file of that class, I had

int CI2cHal::SetI2cSlaveAddress( UCHAR addr, bool force = false )
{
   ...
}

As one can see, I had put the default value of the parameter "force" in the class source file, not in the class header file.

Then I used that function in a derived class as follows (derived class inherited the base class in a public way):

SetI2cSlaveAddress( addr );

assuming it would take the "force" parameter as "false" 'for granted'.

However, the compiler (put in c++11 mode) complained and gave me the following compiler error:

/home/.../mystuff/domoproject/lib/i2cdevs/max6956io.cpp: In member function 'void CMax6956Io::Init(unsigned char, unsigned char, unsigned int)':
/home/.../mystuff/domoproject/lib/i2cdevs/max6956io.cpp:26:30: error: no matching function for call to 'CMax6956Io::SetI2cSlaveAddress(unsigned char&)'

make[1]: *** [lib/i2cdevs/CMakeFiles/i2cdevs.dir/all] Error 2
make: *** [all] Error 2

But when I added the default parameter in the header file of the base class:

int SetI2cSlaveAddress( UCHAR addr, bool force = false );

and removed it from the source file of the base class:

int CI2cHal::SetI2cSlaveAddress( UCHAR addr, bool force )

then the compiler was happy and all code worked as expected (I could give one or two parameters to the function SetI2cSlaveAddress())!

So, not only for the user of a class it's important to put the default value of a parameter in the header file, also compiling and functional wise it apparently seems to be a must!

How about this? It's simple and worked the best for me :)

curl_close($crl);
print_r($rest);

EDIT 1

To debug you can set CURLOPT_HEADER to true to check HTTP response with firebug::net or similar.

curl_setopt($crl, CURLOPT_HEADER, true);

EDIT 2

About Curl error: SSL certificate problem, verify that the CA cert is OK try adding this headers (just to debug, in a production enviroment you should keep these options in true):

curl_setopt($crl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($crl, CURLOPT_SSL_VERIFYPEER, false);

Here an other suggestion to get a GMT Timestamp object:

import java.sql.Timestamp;
import java.util.Calendar;

...

private static Timestamp getGMT() {
   Calendar cal = Calendar.getInstance();
   return new Timestamp(cal.getTimeInMillis()
                       -cal.get(Calendar.ZONE_OFFSET)
                       -cal.get(Calendar.DST_OFFSET));
}

Do it like this:

Go to Settings -> General -> Profiles - tap on your Profile - tap on the Trust button.

but iOS10 has a little change,

Users should go to Settings - General - Device Management - tap on your Profile - tap on Trust button.

I have to say that you are taking on a lot in just 10 weeks, I just finished a semester of Java programming at Indiana University Southeast, and I don't think I have begun to scratch the surface yet. Java is a very strict language in that its syntax is very tough to get a handle on if you have no programming experience at all. I will offer these pieces of advice go to www.bluej.org and down load there, Java compiler it is said to be the easiest to work with and that most college's use this. It is also, what we learned on and from what I know now I can say, they are right. Java is an object oriented language, and Bluej gives you a great understanding of objects. They also show you how to design, classes, methods, array, array list, hash maps, all of that is on this site and it is free. I hope this helps and good luck with your challange.

If you've decided that:

• the thing you need to do is lock on the current object; and
• you want to lock it with granularity smaller than a whole method;

then I don't see the a taboo over synchronizezd(this).

Some people deliberately use synchronized(this) (instead of marking the method synchronized) inside the whole contents of a method because they think it's "clearer to the reader" which object is actually being synchronized on. So long as people are making an informed choice (e.g. understand that by doing so they're actually inserting extra bytecodes into the method and this could have a knock-on effect on potential optimisations), I don't particularly see a problem with this. You should always document the concurrent behaviour of your program, so I don't see the "'synchronized' publishes the behaviour" argument as being so compelling.

As to the question of which object's lock you should use, I think there's nothing wrong with synchronizing on the current object if this would be expected by the logic of what you're doing and how your class would typically be used. For example, with a collection, the object that you would logically expect to lock is generally the collection itself.

Fastest way to do this would be:

int count = 0;
for(int i = 0; i < str.length(); i++) {
     if(Character.isWhitespace(str.charAt(i))) count++;
}

This would catch all characters that are considered whitespace.

Regex solutions require compiling regex and excecuting it - with a lot of overhead. Getting character array requires allocation. Iterating over byte array would be faster, but only if you are sure that your characters are ASCII.

I had

numpy.array(n * [value])

in mind, but apparently that is slower than all other suggestions for large enough n.

Here is full comparison with perfplot (a pet project of mine).

The two empty alternatives are still the fastest (with NumPy 1.12.1). full catches up for large arrays.

Code to generate the plot:

import numpy as np
import perfplot


def empty_fill(n):
    a = np.empty(n)
    a.fill(3.14)
    return a


def empty_colon(n):
    a = np.empty(n)
    a[:] = 3.14
    return a


def ones_times(n):
    return 3.14 * np.ones(n)


def repeat(n):
    return np.repeat(3.14, (n))


def tile(n):
    return np.repeat(3.14, [n])


def full(n):
    return np.full((n), 3.14)


def list_to_array(n):
    return np.array(n * [3.14])


perfplot.show(
    setup=lambda n: n,
    kernels=[empty_fill, empty_colon, ones_times, repeat, tile, full, list_to_array],
    n_range=[2 ** k for k in range(27)],
    xlabel="len(a)",
    logx=True,
    logy=True,
)

The first answer doesn't reflect the current Container vs Presenter paradigm.

If you need to do something, like validate a password, you'd likely have a function that does it. You'd be passing that function to your reusable view as a prop.

Containers

So, the correct way to do it is to write a ValidatorContainer, which will have that function as a property, and wrap the form in it, passing the right props in to the child. When it comes to your view, your validator container wraps your view and the view consumes the containers logic.

Validation could be all done in the container's properties, but it you're using a 3rd party validator, or any simple validation service, you can use the service as a property of the container component and use it in the container's methods. I've done this for restful components and it works very well.

Providers

If there's a bit more configuration necessary, you can use a Provider/Consumer model. A provider is a high level component that wraps somewhere close to and underneath the top application object (the one you mount) and supplies a part of itself, or a property configured in the top layer, to the context API. I then set my container elements to consume the context.

The parent/child context relations don't have to be near each other, just the child has to be descended in some way. Redux stores and the React Router function in this way. I've used it to provide a root restful context for my rest containers (if I don't provide my own).

(note: the context API is marked experimental in the docs, but I don't think it is any more, considering what's using it).

//An example of a Provider component, takes a preconfigured restful.js_x000D_
//object and makes it available anywhere in the application_x000D_
export default class RestfulProvider extends React.Component {_x000D_
 constructor(props){_x000D_
  super(props);_x000D_
_x000D_
  if(!("restful" in props)){_x000D_
   throw Error("Restful service must be provided");_x000D_
  }_x000D_
 }_x000D_
_x000D_
 getChildContext(){_x000D_
  return {_x000D_
   api: this.props.restful_x000D_
  };_x000D_
 }_x000D_
_x000D_
 render() {_x000D_
  return this.props.children;_x000D_
 }_x000D_
}_x000D_
_x000D_
RestfulProvider.childContextTypes = {_x000D_
 api: React.PropTypes.object_x000D_
};

Middleware

A further way I haven't tried, but seen used, is to use middleware in conjunction with Redux. You define your service object outside the application, or at least, higher than the redux store. During store creation, you inject the service into the middleware and the middleware handles any actions that affect the service.

In this way, I could inject my restful.js object into the middleware and replace my container methods with independent actions. I'd still need a container component to provide the actions to the form view layer, but connect() and mapDispatchToProps have me covered there.

The new v4 react-router-redux uses this method to impact the state of the history, for example.

//Example middleware from react-router-redux_x000D_
//History is our service here and actions change it._x000D_
_x000D_
import { CALL_HISTORY_METHOD } from './actions'_x000D_
_x000D_
/**_x000D_
 * This middleware captures CALL_HISTORY_METHOD actions to redirect to the_x000D_
 * provided history object. This will prevent these actions from reaching your_x000D_
 * reducer or any middleware that comes after this one._x000D_
 */_x000D_
export default function routerMiddleware(history) {_x000D_
  return () => next => action => {_x000D_
    if (action.type !== CALL_HISTORY_METHOD) {_x000D_
      return next(action)_x000D_
    }_x000D_
_x000D_
    const { payload: { method, args } } = action_x000D_
    history[method](...args)_x000D_
  }_x000D_
}

You could pipe your grep output into Perl like this:

grep "th" * | perl -n -e'while(/(\w*th\w*)/g) {print "$1\n"}'

I'm new to python too. Here is something that looks like will do what you want to

axes([0.08, 0.08, 0.94-0.08, 0.94-0.08]) #[left, bottom, width, height]
axis('scaled')`

I believe this decides the size of the canvas.

For connection

c=wmi.WMI('machine name',user='username',password='password')

#this connects to remote system. c is wmi object

for commands

process_id, return_value = c.Win32_Process.Create(CommandLine="cmd.exe /c  <your command>")

#this will execute commands

I tried to copy the bootstrap shadow-sm just in the right side, here is my code:

.shadow-rs{
    box-shadow: 5px 0 5px -4px rgba(237, 241, 235, 0.8);
}

There are several ways to create a favicon. The best way for you depends on various factors:

• The time you can spend on this task. For many people, this is "as quick as possible".
• The efforts you are willing to make. Like, drawing a 16x16 icon by hand for better results.
• Specific constraints, like supporting a specific browser with odd specs.

First method: Use a favicon generator

If you want to get the job done well and quickly, you can use a favicon generator. This one creates the pictures and HTML code for all major desktop and mobiles browsers. Full disclosure: I'm the author of this site.

Advantages of such solution: it's quick and all compatibility considerations were already addressed for you.

Second method: Create a favicon.ico (desktop browsers only)

As you suggest, you can create a favicon.ico file which contains 16x16 and 32x32 pictures (note that Microsoft recommends 16x16, 32x32 and 48x48).

Then, declare it in your HTML code:

<link rel="shortcut icon" href="/path/to/icons/favicon.ico">

This method will work with all desktop browsers, old and new. But most mobile browsers will ignore the favicon.

About your suggestion of placing the favicon.ico file in the root and not declaring it: beware, although this technique works on most browsers, it is not 100% reliable. For example Windows Safari cannot find it (granted: this browser is somehow deprecated on Windows, but you get the point). This technique is useful when combined with PNG icons (for modern browsers).

Third method: Create a favicon.ico, a PNG icon and an Apple Touch icon (all browsers)

In your question, you do not mention the mobile browsers. Most of them will ignore the favicon.ico file. Although your site may be dedicated to desktop browsers, chances are that you don't want to ignore mobile browsers altogether.

You can achieve a good compatibility with:

• favicon.ico, see above.
• A 192x192 PNG icon for Android Chrome
• A 180x180 Apple Touch icon (for iPhone 6 Plus; other device will scale it down as needed).

Declare them with

<link rel="shortcut icon" href="/path/to/icons/favicon.ico">
<link rel="icon" type="image/png" href="/path/to/icons/favicon-192x192.png" sizes="192x192">
<link rel="apple-touch-icon" sizes="180x180" href="/path/to/icons/apple-touch-icon-180x180.png">

This is not the full story, but it's good enough in most cases.

If you want to restrict your search only to files you should consider to use -type f in your search

try to use also -iname for case-insensitive search

Example:

find /path -iname 'yourstring*' -type f

You could also perform some operations on results without pipe sign or xargs

Example:

Search for files and show their size in MB

find /path -iname 'yourstring*' -type f -exec du -sm {} \;

You could extend the "string" class to let you return a limited string.

using System;

namespace ConsoleApplication1
{
   class Program
   {
      static void Main(string[] args)
      {
         // since specified strings are treated on the fly as string objects...
         string limit5 = "The quick brown fox jumped over the lazy dog.".LimitLength(5);
         string limit10 = "The quick brown fox jumped over the lazy dog.".LimitLength(10);
         // this line should return us the entire contents of the test string
         string limit100 = "The quick brown fox jumped over the lazy dog.".LimitLength(100);

         Console.WriteLine("limit5   - {0}", limit5);
         Console.WriteLine("limit10  - {0}", limit10);
         Console.WriteLine("limit100 - {0}", limit100);

         Console.ReadLine();
      }
   }

   public static class StringExtensions
   {
      /// <summary>
      /// Method that limits the length of text to a defined length.
      /// </summary>
      /// <param name="source">The source text.</param>
      /// <param name="maxLength">The maximum limit of the string to return.</param>
      public static string LimitLength(this string source, int maxLength)
      {
         if (source.Length <= maxLength)
         {
            return source;
         }

         return source.Substring(0, maxLength);
      }
   }
}

Result:

limit5 - The q
limit10 - The quick
limit100 - The quick brown fox jumped over the lazy dog.

You can add a column to your data using various techniques. The quotes below come from the "Details" section of the relevant help text, [[.data.frame.

Data frames can be indexed in several modes. When [ and [[ are used with a single vector index (x[i] or x[[i]]), they index the data frame as if it were a list.

my.dataframe["new.col"] <- a.vector
my.dataframe[["new.col"]] <- a.vector

The data.frame method for $, treats x as a list

my.dataframe$new.col <- a.vector

When [ and [[ are used with two indices (x[i, j] and x[[i, j]]) they act like indexing a matrix

my.dataframe[ , "new.col"] <- a.vector

Since the method for data.frame assumes that if you don't specify if you're working with columns or rows, it will assume you mean columns.

For your example, this should work:

# make some fake data
your.df <- data.frame(no = c(1:4, 1:7, 1:5), h_freq = runif(16), h_freqsq = runif(16))

# find where one appears and 
from <- which(your.df$no == 1)
to <- c((from-1)[-1], nrow(your.df)) # up to which point the sequence runs

# generate a sequence (len) and based on its length, repeat a consecutive number len times
get.seq <- mapply(from, to, 1:length(from), FUN = function(x, y, z) {
            len <- length(seq(from = x[1], to = y[1]))
            return(rep(z, times = len))
         })

# when we unlist, we get a vector
your.df$group <- unlist(get.seq)
# and append it to your original data.frame. since this is
# designating a group, it makes sense to make it a factor
your.df$group <- as.factor(your.df$group)


   no     h_freq   h_freqsq group

Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".

    /// <summary>
    /// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not 
    /// let the JsonProperty control everything.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class IgnoreJsonPropertyResolver<T> : DefaultContractResolver
    {
        private Dictionary<string, string> PropertyMappings { get; set; }

        public IgnoreJsonPropertyResolver()
        {
            this.PropertyMappings = new Dictionary<string, string>();
            var properties = ReflectionHelper<T>.GetGetProperties(false)();
            foreach (var propertyInfo in properties)
            {
                var jsonProperty = AttributeHelper.GetAttribute<JsonPropertyAttribute>(propertyInfo);
                if (jsonProperty != null)
                {
                    PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
                }
            }
        }

        protected override string ResolvePropertyName(string propertyName)
        {
            string resolvedName = null;
            var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
            return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
        }
    }

Usage:

        var settings = new JsonSerializerSettings();
        settings.DateFormatString = "YYYY-MM-DD";
        settings.ContractResolver = new IgnoreJsonPropertyResolver<PlanViewModel>();
        var model = new PlanViewModel() {Amount = 100};
        var strModel = JsonConvert.SerializeObject(model,settings);

Model:

public class PlanViewModel
{

    /// <summary>
    ///     The customer is charged an amount over an interval for the subscription.
    /// </summary>
    [JsonProperty(PropertyName = "RecurringPrice")]
    public double Amount { get; set; }

    /// <summary>
    ///     Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
    ///     months or years depending on the value for interval_unit.
    /// </summary>
    public int Interval { get; set; } = 1;

    /// <summary>
    ///     Number of free trial days that can be granted when a customer is subscribed to this plan.
    /// </summary>
    public int TrialPeriod { get; set; } = 30;

    /// <summary>
    /// This indicates a one-time fee charged upfront while creating a subscription for this plan.
    /// </summary>
    [JsonProperty(PropertyName = "SetupFee")]
    public double SetupAmount { get; set; } = 0;


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "TypeId")]
    public string Type { get; set; }

    /// <summary>
    /// Billing Frequency
    /// </summary>
    [JsonProperty(PropertyName = "BillingFrequency")]
    public string Period { get; set; }


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "PlanUseType")]
    public string Purpose { get; set; }
}

Just to add some extra detail to the existing answers.

The mod % operation will always perform a complete division and therefore yield a remainder less than the divisor.

x % y = x - (y * floor((x/y)))

An example of a random range finding function with comments:

uint32_t rand_range(uint32_t n, uint32_t m) {
    // size of range, inclusive
    const uint32_t length_of_range = m - n + 1;

    // add n so that we don't return a number below our range
    return (uint32_t)(rand() % length_of_range + n);
}

Another interesting property as per the above:

x % y = x, if x < y

const uint32_t value = rand_range(1, RAND_MAX); // results in rand() % RAND_MAX + 1
// TRUE for all x = RAND_MAX, where x is the result of rand()
assert(value == RAND_MAX);
result of rand()

There are two ways to solve this issue.

1) Skip (using --skip-import in command) default import and create component and once component is created import it manually wherever you want to use it.

ng generate component my-component --skip-import

2) Provide module name explicitly where you want it to be imported

ng generate  component  my-component --module=my-module.module

Select the text in nano with the mouse and then right click on the mouse. Text is now copied to your clipboard. If it does not work try to start nano with the mouse option on : nano -m filename

Very concise solution using recursion:

def gcd(a, b):
    if b == 0:
        return a
    return gcd(b, a%b)

You are right. ArrayList.contains() tests equals(), not object identity:

returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e))

If you got a NullPointerException, verify that you initialized your list, either in a constructor or the declaration. For example:

private List<String> rssFeedURLs = new ArrayList<String>();

You can create your custom SharedPreference class

public class YourPreference {   
    private static YourPreference yourPreference;
    private SharedPreferences sharedPreferences;

    public static YourPreference getInstance(Context context) {
        if (yourPreference == null) {
            yourPreference = new YourPreference(context);
        }
        return yourPreference;
    }

    private YourPreference(Context context) {
        sharedPreferences = context.getSharedPreferences("YourCustomNamedPreference",Context.MODE_PRIVATE);
    }

    public void saveData(String key,String value) {
        SharedPreferences.Editor prefsEditor = sharedPreferences.edit();
        prefsEditor .putString(key, value);
        prefsEditor.commit();           
    }

    public String getData(String key) {
        if (sharedPreferences!= null) {
           return sharedPreferences.getString(key, "");
        }
        return "";         
    }
}

You can get YourPrefrence instance like:

YourPreference yourPrefrence = YourPreference.getInstance(context);
yourPreference.saveData(YOUR_KEY,YOUR_VALUE);

String value = yourPreference.getData(YOUR_KEY);

You can use old C-style programming to do the job. This will require little knowledge about C++. Good for beginners.

For modern C++ language you usually accomplish this through lambda, function objects, ... or algorithm: find, find_if, any_of, for_each, or the new for (auto& v : container) { } syntax. find class algorithm takes more lines of code. You may also write you own template find function for your particular need.

Here is my sample code

#include <iostream>
#include <functional>
#include <algorithm>
#include <vector>

using namespace std;

/**
 * This is old C-like style.  It is mostly gong from 
 * modern C++ programming.  You can still use this
 * since you need to know very little about C++.
 * @param storeSize you have to know the size of store
 *    How many elements are in the array.
 * @return the index of the element in the array,
 *   if not found return -1
 */
int in_array(const int store[], const int storeSize, const int query) {
   for (size_t i=0; i<storeSize; ++i) {
      if (store[i] == query) {
         return i;
      }
   }
   return -1;
}

void testfind() {
   int iarr[] = { 3, 6, 8, 33, 77, 63, 7, 11 };

   // for beginners, it is good to practice a looping method
   int query = 7;
   if (in_array(iarr, 8, query) != -1) {
      cout << query << " is in the array\n";
   }

   // using vector or list, ... any container in C++
   vector<int> vecint{ 3, 6, 8, 33, 77, 63, 7, 11 };
   auto it=find(vecint.begin(), vecint.end(), query);
   cout << "using find()\n";
   if (it != vecint.end()) {
      cout << "found " << query << " in the container\n";
   }
   else {
      cout << "your query: " << query << " is not inside the container\n";
   }

   using namespace std::placeholders;

Say this file is named 'testalgorithm.cpp' you need to compile it with

g++ -std=c++11 -o testalgorithm testalgorithm.cpp

Hope this will help. Please update or add if I have made any mistake.

This solution is for the people who don't use jQuery and to improve performance by not moving the script to bottom of the page, and the problem is that the script is loaded before the html elements are loaded. Add your code in this function body

window.onload=()=>{
    
    // your code here

    // example
    let element=document.getElementById("elementId");
    console.log(element);

};

add everything that has to work only after the document is loaded and keep other functions that has to be executed as soon as the script is loaded outside the function.

I recommend this method instead of moving down the script, because if the script is on top, the browser will try to download it as soon as it sees the script tag, if it is on the bottom of the page, it will take some more time to load it and until that time no event listeners in the script will work. in this case all other functions could be called and the window.onload will get called once everything is loaded.

Unfortunately, combining multiple entity contexts into a single named connection isn't possible. If you want to use named connection strings from a .config file to define your Entity Framework connections, they will each have to have a different name. By convention, that name is typically the name of the context:

<add name="ModEntity" connectionString="metadata=res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
<add name="Entity" connectionString="metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SOMESERVER;Initial Catalog=SOMECATALOG;Persist Security Info=True;User ID=Entity;Password=Entity;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

However, if you end up with namespace conflicts, you can use any name you want and simply pass the correct name to the context when it is generated:

var context = new Entity("EntityV2");

Obviously, this strategy works best if you are using either a factory or dependency injection to produce your contexts.

Another option would be to produce each context's entire connection string programmatically, and then pass the whole string in to the constructor (not just the name).

// Get "Data Source=SomeServer..."
var innerConnectionString = GetInnerConnectionStringFromMachinConfig();
// Build the Entity Framework connection string.
var connectionString = CreateEntityConnectionString("Entity", innerConnectionString);
var context = new EntityContext(connectionString);

How about something like this:

Type contextType = typeof(test_Entities);
string innerConnectionString = ConfigurationManager.ConnectionStrings["Inner"].ConnectionString;
string entConnection = 
    string.Format(
        "metadata=res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl;provider=System.Data.SqlClient;provider connection string=\"{1}\"",
        contextType.Name,
        innerConnectionString);
object objContext = Activator.CreateInstance(contextType, entConnection);
return objContext as test_Entities; 

... with the following in your machine.config:

<add name="Inner" connectionString="Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />

This way, you can use a single connection string for every context in every project on the machine.

you can use json_decode function

foreach (json_decode($response) as $area)
{
 print_r($area); // this is your area from json response
}

Need to install texinfo. configure will still have the cache of its results so it will still think makeinfo is missing. Blow away your source and unpack it again from the tarball. run configure then make.

You could store intermediate values in a cell or column (which you could hide if you choose)

C1: = VLOOKUP(A1, B:B, 1, 0)
D1: = IF(C1 > 10, C1 - 10, C1)

These are ranked in order of difficulty to break your hidden info.

1. Store in cleartext

2. Store encrypted using a symmetric key

3. Using the Android Keystore

4. Store encrypted using asymmetric keys

The Keystore itself is encrypted using the user’s own lockscreen pin/password, hence, when the device screen is locked the Keystore is unavailable. Keep this in mind if you have a background service that could need to access your application secrets.

You can overwrite a string, as follows:

String myName = "halftime";
myName = myName.substring(0,4)+'x'+myName.substring(5);  

Note that the string myName occurs on both lines, and on both sides of the second line.

Therefore, even though strings may technically be immutable, in practice, you can treat them as editable by overwriting them.

Use DataTypeConverter classjavax.xml.bind.DataTypeConverter

String hexString = DatatypeConverter.printHexBinary(bytes[] raw);
