Try using the ArrayIntList from the apache framework. It works exactly like an arraylist, except it can hold primitive int.

Below is the code for getting the hardware string, but you need to compare these hardware string to know which device it is. I have created a class for that contains almost all the device strings(we're keeping string upto date with new devices). It's easy to use please check

Swift : GitHub/DeviceGuru

Objective-C : GitHub/DeviceUtil

public func hardwareString() -> String {
  var name: [Int32] = [CTL_HW, HW_MACHINE]
  var size: Int = 2
  sysctl(&name, 2, nil, &size, &name, 0)
  var hw_machine = [CChar](count: Int(size), repeatedValue: 0)
  sysctl(&name, 2, &hw_machine, &size, &name, 0)

  let hardware: String = String.fromCString(hw_machine)!
  return hardware
}

String dir="/Attendancesystem";

 public void displaypdf() {

        File file = null;
            file = new File(Environment.getExternalStorageDirectory()+dir+ "/sample.pdf");
        Toast.makeText(getApplicationContext(), file.toString() , Toast.LENGTH_LONG).show();
        if(file.exists()) {
            Intent target = new Intent(Intent.ACTION_VIEW);
            target.setDataAndType(Uri.fromFile(file), "application/pdf");
            target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

            Intent intent = Intent.createChooser(target, "Open File");
            try {
                startActivity(intent);
            } catch (ActivityNotFoundException e) {
                // Instruct the user to install a PDF reader here, or something
            }
        }
        else
            Toast.makeText(getApplicationContext(), "File path is incorrect." , Toast.LENGTH_LONG).show();
    }

Instead of having a fat APK file, I would like to use just the armeabi files and remove the armeabi-v7a folder.

The opposite is a much better strategy. If you have minSdkVersion to 14 and upload your apk to the play store, you'll notice you'll support the same number of devices whether you support armeabi or not. Therefore, there are no devices with Android 4 or higher which would benefit from armeabi at all.

This is probably why the Android NDK doesn't even support armeabi anymore as per revision r17b. [source]

None of the above filters fixed my issue so I had to copy the filter from official github doc. And then use it as explained in the above answers

angular.module('yourAppNameHere').filter('unique', function () {

return function (items, filterOn) {

if (filterOn === false) {
  return items;
}

if ((filterOn || angular.isUndefined(filterOn)) && angular.isArray(items)) {
  var hashCheck = {}, newItems = [];

  var extractValueToCompare = function (item) {
    if (angular.isObject(item) && angular.isString(filterOn)) {
      return item[filterOn];
    } else {
      return item;
    }
  };

  angular.forEach(items, function (item) {
    var valueToCheck, isDuplicate = false;

    for (var i = 0; i < newItems.length; i++) {
      if (angular.equals(extractValueToCompare(newItems[i]), extractValueToCompare(item))) {
        isDuplicate = true;
        break;
      }
    }
    if (!isDuplicate) {
      newItems.push(item);
    }

  });
  items = newItems;
}
return items;
  };

});

you can use this solution:

items = { 'a', 'b' }
for k,v in pairs(items) do 
 if v == 'a' then 
  --do something
 else 
  --do something
 end
end

or

items = {'a', 'b'}
for k,v in pairs(items) do 
  while v do
    if v == 'a' then 
      return found
    else 
      break
    end
  end 
 end 
return nothing

I created simple examples to clarify understanding of ManualResetEvent vs AutoResetEvent.

AutoResetEvent: lets assume you have 3 workers thread. If any of those threads will call WaitOne() all other 2 threads will stop execution and wait for signal. I am assuming they are using WaitOne(). It is like; if I do not work, nobody works. In first example you can see that

autoReset.Set();
Thread.Sleep(1000);
autoReset.Set();

When you call Set() all threads will work and wait for signal. After 1 second I am sending second signal and they execute and wait (WaitOne()). Think about these guys are soccer team players and if one player says I will wait until manager calls me, and others will wait until manager tells them to continue (Set())

public class AutoResetEventSample
{
    private AutoResetEvent autoReset = new AutoResetEvent(false);

    public void RunAll()
    {
        new Thread(Worker1).Start();
        new Thread(Worker2).Start();
        new Thread(Worker3).Start();
        autoReset.Set();
        Thread.Sleep(1000);
        autoReset.Set();
        Console.WriteLine("Main thread reached to end.");
    }

    public void Worker1()
    {
        Console.WriteLine("Entered in worker 1");
        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker1 is running {0}", i);
            Thread.Sleep(2000);
            autoReset.WaitOne();
        }
    }
    public void Worker2()
    {
        Console.WriteLine("Entered in worker 2");

        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker2 is running {0}", i);
            Thread.Sleep(2000);
            autoReset.WaitOne();
        }
    }
    public void Worker3()
    {
        Console.WriteLine("Entered in worker 3");

        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker3 is running {0}", i);
            Thread.Sleep(2000);
            autoReset.WaitOne();
        }
    }
}

In this example you can clearly see that when you first hit Set() it will let all threads go, then after 1 second it signals all threads to wait! As soon as you set them again regardless they are calling WaitOne() inside, they will keep running because you have to manually call Reset() to stop them all.

manualReset.Set();
Thread.Sleep(1000);
manualReset.Reset();
Console.WriteLine("Press to release all threads.");
Console.ReadLine();
manualReset.Set();

It is more about Referee/Players relationship there regardless of any of the player is injured and wait for playing others will continue to work. If Referee says wait (Reset()) then all players will wait until next signal.

public class ManualResetEventSample
{
    private ManualResetEvent manualReset = new ManualResetEvent(false);

    public void RunAll()
    {
        new Thread(Worker1).Start();
        new Thread(Worker2).Start();
        new Thread(Worker3).Start();
        manualReset.Set();
        Thread.Sleep(1000);
        manualReset.Reset();
        Console.WriteLine("Press to release all threads.");
        Console.ReadLine();
        manualReset.Set();
        Console.WriteLine("Main thread reached to end.");
    }

    public void Worker1()
    {
        Console.WriteLine("Entered in worker 1");
        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker1 is running {0}", i);
            Thread.Sleep(2000);
            manualReset.WaitOne();
        }
    }
    public void Worker2()
    {
        Console.WriteLine("Entered in worker 2");

        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker2 is running {0}", i);
            Thread.Sleep(2000);
            manualReset.WaitOne();
        }
    }
    public void Worker3()
    {
        Console.WriteLine("Entered in worker 3");

        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Worker3 is running {0}", i);
            Thread.Sleep(2000);
            manualReset.WaitOne();
        }
    }
}

Yes, you're missing using cursors

DECLARE
  CURSOR foo_cur IS 
    SELECT NEEDED_FIELD WHERE condition ;
BEGIN
  OPEN foo_cur;
  FETCH foo_cur INTO foo_rec;
  IF foo_cur%FOUND THEN
     ...
  END IF;
  CLOSE foo_cur;
EXCEPTION
  WHEN OTHERS THEN
    CLOSE foo_cur;
    RAISE;
END ;

admittedly this is more code, but it doesn't use EXCEPTIONs as flow-control which, having learnt most of my PL/SQL from Steve Feuerstein's PL/SQL Programming book, I believe to be a good thing.

Whether this is faster or not I don't know (I do very little PL/SQL nowadays).

The other answers explain how to produce a string formatted like in your example, but if all you need to do is to print that stuff you could simply write:

first = 10
second = 20
print "First number is", first, "and second number is", second

U can also try this

$("#dialog").dialog({
            autoOpen: false,
            resizable: true,
            height: 400,
            width: 150,
            position: 'center',
            title: 'Term Sheet',
            beforeClose: function(event, ui) { 
               console.log('Event Fire');
            },
            modal: true,
            buttons: {
                "Submit": function () {
                    $(this).dialog("close");
                },
                "Cancel": function () {
                    $(this).dialog("close");
                }
            }
        });

Similarly with OUTER JOINs, the word "OUTER" is optional. It's the LEFT or RIGHT keyword that makes the JOIN an "OUTER" JOIN.

However for some reason I always use "OUTER" as in LEFT OUTER JOIN and never LEFT JOIN, but I never use INNER JOIN, but rather I just use "JOIN":

SELECT ColA, ColB, ...
FROM MyTable AS T1
     JOIN MyOtherTable AS T2
         ON T2.ID = T1.ID
     LEFT OUTER JOIN MyOptionalTable AS T3
         ON T3.ID = T1.ID

You will get the error on REFRESH_FAST, if you do not create materialized view logs for the master table(s) the query is referring to. If anyone is not familiar with materialized views or using it for the first time, the better way is to use oracle sqldeveloper and graphically put in the options, and the errors also provide much better sense.

For mac users: in new version there is no setting.xml, alternate way is to

navigate to SmartGit preferences folder using terminal

cd /Library/Preferences/SmartGit/

use ls command to see list of folders .. simply delete SmartGit version folder you find using command rm -r <main-smartgit-version> and reopen the SmartGit app. :)

There are a few good answers posted here, but I think you can simplify your code and skip the check for inputElement.selectionStart support: it is not supported only on IE8 and earlier (see documentation) which represents less than 1% of the current browser usage.

var input = document.getElementById('myinput'); // or $('#myinput')[0]
var caretPos = input.selectionStart;

// and if you want to know if there is a selection or not inside your input:

if (input.selectionStart != input.selectionEnd)
{
    var selectionValue =
    input.value.substring(input.selectionStart, input.selectionEnd);
}

I've tried to find a "fit to screen" property but there is no such.

But setting widget's "maximumSize" to a "some big number" ( like 2000 x 2000 ) will automatically fit the widget to the parent widget space.

One also may use the following to catch the errors:

$.ajax({
    url: url, 
    success: function (data) {
        // Handle success here
        $('#editor-content-container').html(data);
        $('#editor-container').modal('show');
    },
    cache: false
}).fail(function (jqXHR, textStatus, error) {
    // Handle error here
    $('#editor-content-container').html(jqXHR.responseText);
    $('#editor-container').modal('show');
});

1) you can float the image to the left:

<img style="float:left" src="http://i.imgur.com/hCrQkJi.png">

2)You can use an HTML table to place elements on one line.

Code below

  <div class="navigation-bar">
    <div id="navigation-container">
      <table>
        <tr>
          <td><img src="http://i.imgur.com/hCrQkJi.png"></td>
          <td><ul>
            <li><a href="#">Home</a></li>
            <li><a href="#">Projects</a></li>
            <li><a href="#">About</a></li>
            <li><a href="#">Services</a></li>
            <li><a href="#">Get in Touch</a></li>
        </ul>
          </td></tr></table>
    </div>

In a Ruby on Rails project by default the root of the HTML source for the server is the public directory. So your link would be:

<img src="images/rss.jpg" alt="rss feed" />

But it is best practice in a Rails project to use the built in helper:

<%= image_tag("rss.jpg", :alt => "rss feed") %>

That will create the correct image link plus if you ever add assert servers, etc it will work with those.

Yes, you can install an interrupt handler using the module signal, and wait forever using a threading.Event:

import signal
import sys
import time
import threading

def signal_handler(signal, frame):
    print('You pressed Ctrl+C!')
    sys.exit(0)

signal.signal(signal.SIGINT, signal_handler)
print('Press Ctrl+C')
forever = threading.Event()
forever.wait()

why don't you try this?

password="your password"
username="username"
Ip="<IP>"
sshpass -p "$password" scp /<PATH>/final.txt $username@$Ip:/root/<PATH>

I'm a bit confused by the quotes, however, below should work for you:

SELECT "Gc_Staff_Number",
       "Start_Date", x.end_date
FROM   "Employment_History" eh,
(SELECT "End_Date"
        FROM   "Employment_History"
        WHERE  "Current_Flag" != 'Y'
               AND ROWNUM = 1
               AND "Employee_Number" = eh.Employee_Number
        ORDER  BY "End_Date" ASC) x
WHERE  "Current_Flag" = 'Y'

Mark Russinovich wrote a terrific tool called AccessChk that lets you get this information from the command line. No installation is necessary.

http://technet.microsoft.com/en-us/sysinternals/bb664922.aspx

For example:

accesschk.exe /accepteula -q -a SeServiceLogonRight

Returns this for me:

IIS APPPOOL\DefaultAppPool
IIS APPPOOL\Classic .NET AppPool
NT SERVICE\ALL SERVICES

By contrast, whoami /priv and whoami /all were missing some entries for me, like SeServiceLogonRight.

First Add a Class called Win32.cs

public class Win32
{ 
    [DllImport("User32.Dll")]
    public static extern long SetCursorPos(int x, int y);

    [DllImport("User32.Dll")]
    public static extern bool ClientToScreen(IntPtr hWnd, ref POINT point);

    [StructLayout(LayoutKind.Sequential)]
    public struct POINT
    {
        public int x;
        public int y;

        public POINT(int X, int Y)
        {
            x = X;
            y = Y;
        }
    }
}

You can use it then like this:

Win32.POINT p = new Win32.POINT(xPos, yPos);

Win32.ClientToScreen(this.Handle, ref p);
Win32.SetCursorPos(p.x, p.y);

What is the __main__.py file for?

When creating a Python module, it is common to make the module execute some functionality (usually contained in a main function) when run as the entry point of the program. This is typically done with the following common idiom placed at the bottom of most Python files:

if __name__ == '__main__':
    # execute only if run as the entry point into the program
    main()

You can get the same semantics for a Python package with __main__.py, which might have the following structure:

.
+-- demo
    +-- __init__.py
    +-- __main__.py

To see this, paste the below into a Python 3 shell:

from pathlib import Path

demo = Path.cwd() / 'demo'
demo.mkdir()

(demo / '__init__.py').write_text("""
print('demo/__init__.py executed')

def main():
    print('main() executed')
""")

(demo / '__main__.py').write_text("""
print('demo/__main__.py executed')

from demo import main

main()
""")

We can treat demo as a package and actually import it, which executes the top-level code in the __init__.py (but not the main function):

>>> import demo
demo/__init__.py executed

When we use the package as the entry point to the program, we perform the code in the __main__.py, which imports the __init__.py first:

$ python -m demo
demo/__init__.py executed
demo/__main__.py executed
main() executed

You can derive this from the documentation. The documentation says:

__main__ — Top-level script environment

'__main__' is the name of the scope in which top-level code executes. A module’s __name__ is set equal to '__main__' when read from standard input, a script, or from an interactive prompt.

A module can discover whether or not it is running in the main scope by checking its own __name__, which allows a common idiom for conditionally executing code in a module when it is run as a script or with python -m but not when it is imported:

if __name__ == '__main__':
     # execute only if run as a script
     main()

For a package, the same effect can be achieved by including a __main__.py module, the contents of which will be executed when the module is run with -m.

Zipped

You can also zip up this directory, including the __main__.py, into a single file and run it from the command line like this - but note that zipped packages can't execute sub-packages or submodules as the entry point:

from pathlib import Path

demo = Path.cwd() / 'demo2'
demo.mkdir()

(demo / '__init__.py').write_text("""
print('demo2/__init__.py executed')

def main():
    print('main() executed')
""")

(demo / '__main__.py').write_text("""
print('demo2/__main__.py executed')

from __init__ import main

main()
""")

Note the subtle change - we are importing main from __init__ instead of demo2 - this zipped directory is not being treated as a package, but as a directory of scripts. So it must be used without the -m flag.

Particularly relevant to the question - zipapp causes the zipped directory to execute the __main__.py by default - and it is executed first, before __init__.py:

$ python -m zipapp demo2 -o demo2zip
$ python demo2zip
demo2/__main__.py executed
demo2/__init__.py executed
main() executed

Note again, this zipped directory is not a package - you cannot import it either.

Roughly you can do it like that :

try
{
    //do something
}
catch (Exception ex)
{
    string script = "<script>alert('" + ex.Message + "');</script>";
    if (!Page.IsStartupScriptRegistered("myErrorScript"))
    {
         Page.ClientScript.RegisterStartupScript("myErrorScript", script);
    }
}

But I recommend you to define your custom Exception and throw it anywhere you need. At your page catch this custom exception and register your message box script.

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

• Right click Computer
• Click the properties
• On the left pane select Advanced System Settings
• Select Environment Variables
• Under the System Variables, Select PATH and click edit,
  and then click new and add path as C:\Program
  Files\Java\jdk1.8.0_131\bin (depending on your installation path)
  and finally click ok
• Next restart your command prompt and open it and try javac

In the current version of safari this is not working anymore. You have to define the second parameter as non-passive by passing {passiv:false}

 document.addEventListener('touchmove', function(e) {
 e.preventDefault();
}, { passive: false });

break is to break out of a loop like for, while, switch etc which you don't have here, you need to use return to break the execution flow of the current function and return to the caller.

function loop() {
    if (isPlaying) {
        jet1.draw();
        drawAllEnemies();
        requestAnimFrame(loop);
        if (game == 1) {
           return
        }
    }
}

Note: This does not cover the logic behind the if condition or when to return from the method, for that we need to have more context regarding the drawAllEnemies and requestAnimFrame method as well as how game value is updated

You can use:

git config --list

or look at your ~/.gitconfig file. The local configuration will be in your repository's .git/config file.

Use:

git config --list --show-origin

to see where that setting is defined (global, user, repo, etc...)

Transaction is an indivisible unit of data processing -All transactions must have the ACID properties:

ie:Atomicity,Consistency,Isolation and Durable Transaction is all or nothing but not intermidiate (it means if you transfer your money from one account to another account,one account have to lose that much and other one have to gain that amount,but if you transfer money from one account and another account is still empty that will be not a transaction)

ThisWorkbook.Sheets.Add After:=Sheets(Sheets.Count)
ActiveSheet.Name = "XYZ"

(when you add a worksheet, anyway it'll be the active sheet)

In Python, you can use urllib2 (http://docs.python.org/2/library/urllib2.html) to do all of that work for you.

Simply enough:

import urllib2
f =  urllib2.urlopen(url)
print f.read() 

Will print the received HTTP response.

To pass GET/POST parameters the urllib.urlencode() function can be used. For more information, you can refer to the Official Urllib2 Tutorial

You're searching for gc_maxlifetime, see http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime for a description.

Your session will last 1440 seconds which is 24 minutes (default).

C++20 will add constexpr strings and vectors

The following proposal has been accepted apparently: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0980r0.pdf and it adds constructors such as:

// 20.3.2.2, construct/copy/destroy
constexpr
basic_string() noexcept(noexcept(Allocator())) : basic_string(Allocator()) { }
constexpr
explicit basic_string(const Allocator& a) noexcept;
constexpr
basic_string(const basic_string& str);
constexpr
basic_string(basic_string&& str) noexcept;

in addition to constexpr versions of all / most methods.

There is no support as of GCC 9.1.0, the following fails to compile:

#include <string>

int main() {
    constexpr std::string s("abc");
}

with:

g++-9 -std=c++2a main.cpp

with error:

error: the type ‘const string’ {aka ‘const std::__cxx11::basic_string<char>’} of ‘constexpr’ variable ‘s’ is not literal

std::vector discussed at: Cannot create constexpr std::vector

Tested in Ubuntu 19.04.

You need to open the connection first:

 SQLConnection.Open();

As Alex says, it works very well. The only tricky part is to remember to make any changes in the cmake files, rather than from within Visual Studio. So on all platforms, the workflow is similar to if you'd used plain old makefiles.

But it's fairly easy to work with, and I've had no issues with cmake generating invalid files or anything like that, so I wouldn't worry too much.

Here is a way to do it with a closure:

    def generate_add_mult_func(func):
        def function_generator(x):
            return reduce(func,range(1,x))
        return function_generator

    def add(x,y):
        return x+y

    def mult(x,y):
        return x*y

    adding=generate_add_mult_func(add)
    multiplying=generate_add_mult_func(mult)

    print adding(10)
    print multiplying(10)

You may also consider the ToolStripButton control if you don't mind hosting it in a ToolStripContainer. I think it can natively support pressed and unpressed states.

On PostgreSQL you can use:

SELECT * FROM table_name WHERE (boolean_column IS NULL OR NOT boolean_column)

Considering all of your API requests located with a url pattern of /api/.. you can tell spring to secure only this url pattern by using below configuration. Which means that you are telling spring what to secure instead of what to ignore.

protected void configure(HttpSecurity http) throws Exception {
  http
    .csrf().disable()
     .authorizeRequests()
      .antMatchers("/api/**").authenticated()
      .anyRequest().permitAll()
      .and()
    .httpBasic().and()
    .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}

In my case I had a primary key in the database that had an accent, but in other table its foreign key didn't have. For some reason, MySQL allowed this.

1. On the menu bar, select Window ? Preferences
2. Set the font size (General ? Appearance ? Colors and Fonts ? Structured Text Editors ? Structured Text Editor Text Font (set to default: Text Font) ? Edit...).
3. Save the preferences.

My method of doing this has been to create an inherited class that explicitly implements IDisposable. This is useful for folks who use the gui to add the service reference ( Add Service Reference ). I just drop this class in the project making the service reference and use it instead of the default client:

using System;
using System.ServiceModel;
using MyApp.MyService; // The name you gave the service namespace

namespace MyApp.Helpers.Services
{
    public class MyServiceClientSafe : MyServiceClient, IDisposable
    {
        void IDisposable.Dispose()
        {
            if (State == CommunicationState.Faulted)
            {
                Abort();
            }
            else if (State != CommunicationState.Closed)
            {
                Close();
            }

            // Further error checks and disposal logic as desired..
        }
    }
}

Note: This is just a simple implementation of dispose, you can implement more complex dispose logic if you like.

You can then replace all your calls made with the regular service client with the safe clients, like this:

using (MyServiceClientSafe client = new MyServiceClientSafe())
{
    var result = client.MyServiceMethod();
}

I like this solution as it does not require me to have access to the Interface definitions and I can use the using statement as I would expect while allowing my code to look more or less the same.

You will still need to handle the exceptions which can be thrown as pointed out in other comments in this thread.

Here's an updated answer for Angular 4 & 5. TransformRequest and angular.identity were dropped. I've also included the ability to combine files with JSON data in one request.

Angular 5 Solution:

import {HttpClient} from '@angular/common/http';

uploadFileToUrl(files, restObj, uploadUrl): Promise<any> {
  // Note that setting a content-type header
  // for mutlipart forms breaks some built in
  // request parsers like multer in express.
  const options = {} as any; // Set any options you like
  const formData = new FormData();

  // Append files to the virtual form.
  for (const file of files) {
    formData.append(file.name, file)
  }

  // Optional, append other kev:val rest data to the form.
  Object.keys(restObj).forEach(key => {
    formData.append(key, restObj[key]);
  });

  // Send it.
  return this.httpClient.post(uploadUrl, formData, options)
    .toPromise()
    .catch((e) => {
      // handle me
    });
}

Angular 4 Solution:

// Note that these imports below are deprecated in Angular 5
import {Http, RequestOptions} from '@angular/http';

uploadFileToUrl(files, restObj, uploadUrl): Promise<any> {
  // Note that setting a content-type header
  // for mutlipart forms breaks some built in
  // request parsers like multer in express.
  const options = new RequestOptions();
  const formData = new FormData();

  // Append files to the virtual form.
  for (const file of files) {
    formData.append(file.name, file)
  }

  // Optional, append other kev:val rest data to the form.
  Object.keys(restObj).forEach(key => {
    formData.append(key, restObj[key]);
  });

  // Send it.
  return this.http.post(uploadUrl, formData, options)
    .toPromise()
    .catch((e) => {
      // handle me
    });
}

This work for me:

public static void main(String[] args) {

        Properties props = new Properties();
        props.load(new FileInputStream("src/log4j.properties"));
        PropertyConfigurator.configure(props);

FYI, [ChildActionOnly] is not available in ASP.NET MVC Core. see some info here

It has no meaning, it is just a file extension. It is some people's convention to name files with a .inc extension if that file is designed to be included by other PHP files, but it is only convention.

It does have a possible disadvantage which is that servers normally are not configured to parse .inc files as php, so if the file sits in your web root and your server is configured in the default way, a user could view your php source code in the .inc file by visiting the URL directly.

Its only possible advantage is that it is easy to identify which files are used as includes. Although simply giving them a .php extension and placing them in an includes folder has the same effect without the disadvantage mentioned above.

Try like this:

$data = array('current_login' => date('Y-m-d H:i:s'));
$this->db->set('last_login', 'current_login', false);
$this->db->where('id', 'some_id');
$this->db->update('login_table', $data);

Pay particular attention to the set() call's 3rd parameter. false prevents CodeIgniter from quoting the 2nd parameter -- this allows the value to be treated as a table column and not a string value. For any data that doesn't need to special treatment, you can lump all of those declarations into the $data array.

The query generated by above code:

UPDATE `login_table`
SET last_login = current_login, `current_login` = '2018-01-18 15:24:13'
WHERE `id` = 'some_id'

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

An optimized version of the implementation of the reverse function proposed by @michieljoris (according to the comments of @Beterraba and @Mala):

function a2hex(str) {_x000D_
  var hex = '';_x000D_
  for (var i = 0, l = str.length; i < l; i++) {_x000D_
    var hexx = Number(str.charCodeAt(i)).toString(16);_x000D_
    hex += (hexx.length > 1 && hexx || '0' + hexx);_x000D_
  }_x000D_
  return hex;_x000D_
}_x000D_
alert(a2hex('2460')); // display 32343630

You can put an apostrophe in a single quoted JavaScript string by escaping it with a backslash, like so:

theAnchorText = 'I\'m home';

You can make it by one line:

mymap := map[string]interface{}{"foo": map[string]interface{}{"first": 1}, "boo": map[string]interface{}{"second": 2}}
for k, v := range mymap {
    fmt.Println("k:", k, "v:", v)
}

Output is:

k: foo v: map[first:1]
k: boo v: map[second:2]

An abstract class can be used instead of an interface (in C# 7.3).

// Like interface
abstract class IIO
{
    public virtual async Task<string> DoOperation(string Name)
    {
        throw new NotImplementedException(); // throwing exception
        // return await Task.Run(() => { return ""; }); // or empty do
    }
}

// Implementation
class IOImplementation : IIO
{
    public override async Task<string> DoOperation(string Name)
    {
        return await await Task.Run(() =>
        {
            if(Name == "Spiderman")
                return "ok";
            return "cancel";
        }); 
    }
}

I've made basic black launch screens that will make the app scale properly on the iPhone 6 and iPhone 6+:

iPhone 6 Portrait

iPhone 6 Plus Portrait

If you already have a LaunchImage in your .xcassett, open it, switch to the third tab in the right menu in Xcode and tick the iOS 8.0 iPhone images to add them to the existing set. Then drag the images over:

If using sqlplus you can define a variable thus:

define <varname>=<varvalue>

And you can display the value by:

define <varname>

And then use it in a query as, for example:

select *
from tab1
where col1 = '&varname';

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-file-extracting so just double click the file to start installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add C:\opencv\build\x86\mingw\bin directory to your system PATH. This directory contains OpenCV DLLs which is required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

You will see a window like shown below:

On the System Variables section,
select Path (1), click Edit... (2), add C:\opencv\build\x86\mingw\bin (3) then click Ok.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Installing MinGW compiler suite

I highly recommend you to use gcc (GNU Compiler Collection) for compiling your code. gcc is the compiler suite widely available in Linux systems and MinGW is the native port for Windows.

Download the MinGW installer from Sourceforge.net and double click to start installation. Just follow the wizard and select the directory to be installed, say C:\MinGW.

Select "C Compiler" and "C++ Compiler" to be installed.

The installer will download some packages from the internet so you have to wait for a while. After the installation finished, add C:\MinGW\bin to your system path using the steps described before.

To test if your MinGW installation is success, open a command-line box and type: gcc. If everything is ok, it will display this message:

gcc: fatal error: no input files
compilation terminated

This completes the MinGW installation, now is the time to write your "Hello, World!" program.

3. Write a sample code

Open your text editor and type the code below and save the file to loadimg.cpp.

#include "opencv2/highgui/highgui.hpp"
#include <iostream>

using namespace cv;
using namespace std;

int main(int argc, char** argv)
{
  Mat im = imread(argc == 2 ? argv[1] : "lena.jpg", 1);
  if (im.empty())
  {
    cout << "Cannot open image!" << endl;
    return -1;
  }

  imshow("image", im);
  waitKey(0);

  return 0;
}

Put lena.jpg or any image you like in the same directory with the file above. Open a command-line box and compile the code above by typing:

g++ -I"C:\opencv\build\include" -L"C:\opencv\build\x86\mingw\lib" loadimg.cpp -lopencv_core243 -lopencv_highgui243 -o loadimg

If it compiles successfully, it will create an executable named loadimg.exe.

Type:

loadimg

To execute the program. Result:

4. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → C:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

File file = new File(path, name);

    MimeTypeMap mime = MimeTypeMap.getSingleton();
    int index = file.getName().lastIndexOf('.')+1;
    String ext = file.getName().substring(index).toLowerCase();
    String type = mime.getMimeTypeFromExtension(ext);

    intent.setDataAndType(Uri.fromFile(file), type);
    try
    {
      context.startActivity(intent);
    }
    catch(ActivityNotFoundException ex)
    {
        ex.printStackTrace();

    }

Here is the solution which worked very fine for me, if it can help :

/**
* Add the equals method to the jquery objects
*/
$.fn.equals = function(compareTo) {
  if (!compareTo || this.length !== compareTo.length) {
    return false;
  }
  for (var i = 0; i < this.length; ++i) {
    if (this[i] !== compareTo[i]) {
      return false;
    }
  }
  return true;
};

/**
 * Activate popover message for all concerned fields
 */
var popoverOpened = null;
$(function() { 
    $('span.btn').popover();
    $('span.btn').unbind("click");
    $('span.btn').bind("click", function(e) {
        e.stopPropagation();
        if($(this).equals(popoverOpened)) return;
        if(popoverOpened !== null) {
            popoverOpened.popover("hide");            
        }
        $(this).popover('show');
        popoverOpened = $(this);
        e.preventDefault();
    });

    $(document).click(function(e) {
        if(popoverOpened !== null) {
            popoverOpened.popover("hide");   
            popoverOpened = null;
        }        
    });
});

If you want to use steffens21's approach with unittest.TestLoader, you can modify the original test loader (see unittest.py):

import unittest
from unittest import suite

class TestLoaderWithKwargs(unittest.TestLoader):
    """A test loader which allows to parse keyword arguments to the
       test case class."""
    def loadTestsFromTestCase(self, testCaseClass, **kwargs):
        """Return a suite of all tests cases contained in 
           testCaseClass."""
        if issubclass(testCaseClass, suite.TestSuite):
            raise TypeError("Test cases should not be derived from "\
                            "TestSuite. Maybe you meant to derive from"\ 
                            " TestCase?")
        testCaseNames = self.getTestCaseNames(testCaseClass)
        if not testCaseNames and hasattr(testCaseClass, 'runTest'):
            testCaseNames = ['runTest']

        # Modification here: parse keyword arguments to testCaseClass.
        test_cases = []
        for test_case_name in testCaseNames:
            test_cases.append(testCaseClass(test_case_name, **kwargs))
        loaded_suite = self.suiteClass(test_cases)

        return loaded_suite 

# call your test
loader = TestLoaderWithKwargs()
suite = loader.loadTestsFromTestCase(MyTest, extraArg=extraArg)
unittest.TextTestRunner(verbosity=2).run(suite)

Beware of triggers. Maybe the issue is with some operation in the trigger for inserted rows.

For simple commands you can use:

ssh <ssh_args> command1 '&&' command2

or

ssh <ssh_args> command1 \&\& command2

A web api endpoint (controller) is a single resource that accepts get/post/put/delete verbs. It is not a normal MVC controller.

Necessarily, at /api/VTRouting there can only be one HttpPost method that accepts the parameters you are sending. The function name does not matter, as long as you are decorating with the [http] stuff. I've never tried, though.

Edit: This does not work. In resolving, it seems to go by the number of parameters, not trying to model-bind to the type.

You can overload the functions to accept different parameters. I am pretty sure you would be OK if you declared it the way you do, but used different (incompatible) parameters to the methods. If the params are the same, you are out of luck as model binding won't know which one you meant.

[HttpPost]
public MyResult Route(MyRequestTemplate routingRequestTemplate) {...}

[HttpPost]
public MyResult TSPRoute(MyOtherTemplate routingRequestTemplate) {...}

This part works

The default template they give when you create a new one makes this pretty explicit, and I would say you should stick with this convention:

public class ValuesController : ApiController
{
    // GET is overloaded here.  one method takes a param, the other not.
    // GET api/values  
    public IEnumerable<string> Get() { .. return new string[] ... }
    // GET api/values/5
    public string Get(int id) { return "hi there"; }

    // POST api/values (OVERLOADED)
    public void Post(string value) { ... }
    public void Post(string value, string anotherValue) { ... }
    // PUT api/values/5
    public void Put(int id, string value) {}
    // DELETE api/values/5
    public void Delete(int id) {}
}

If you want to make one class that does many things, for ajax use, there is no big reason to not use a standard controller/action pattern. The only real difference is your method signatures aren't as pretty, and you have to wrap things in Json( returnValue) before you return them.

Edit:

Overloading works just fine when using the standard template (edited to include) when using simple types. I've gone and tested the other way too, with 2 custom objects with different signatures. Never could get it to work.

• Binding with complex objects doesn't look "deep", so thats a no-go
• You could get around this by passing an extra param, on the query string
• A better writeup than I can give on available options

This worked for me in this case, see where it gets you. Exception for testing only.

public class NerdyController : ApiController
{
    public void Post(string type, Obj o) { 
        throw new Exception("Type=" + type + ", o.Name=" + o.Name ); 
    }
}

public class Obj {
    public string Name { get; set; }
    public string Age { get; set; }
}

And called like this form the console:

$.post("/api/Nerdy?type=white", { 'Name':'Slim', 'Age':'21' } )

Well.... My answer may be considered naive but in fact it has been the only way MongoDB has work in my case, Ubuntu 19.10. I tried to run the commands from the most voted comments and none worked, when running:

mongod --repair

I got this alert:

With some research I found out that running the DB in another port could be a solution, then:

mongod --port 27018

And it works great for me every time. Long answer but wanted to give context before giving such a simple solution.

(If I'm doing it wrong or doesn't seem logical, plz tell me! Relevant for me)

In order to create the drawable directory structure for different image densities, You need to:

1. Right-click on the \res folder
2. Select new > android resource directory

3. In the New Resource Directory window, under Available qualifiers resource type section, select drawable.

4. Add density and choose the appropriate size.

one line solution: basic idea:

$('sth').click(function () {
    let COND = $(this).propery == 'cond1' ? 'cond2' : 'cond1';
    doSomeThing(COND);
})

examples on jsfiddle

example 1, changing innerHTML of an element in a toggle-mode:

$('#clickTest1').click(function () {
    $(this).html($(this).html() == 'click Me' ? 'clicked' : 'click Me');
});

example 2, toggling displays between "none" and "inline-block":

$('#clickTest2, #clickTest2 > span').click(function () {
    $(this).children().css('display', $(this).children().css('display') == 'inline-block' ? 'none' : 'inline-block');
});

If you absolutely position the elements inside the div, you can set the padding top and bottom to 50%.

So something like this:

#s7 {
    position: relative;
    width:100%;
    padding: 50% 0;
    margin:auto;
    overflow: hidden;
    z-index:1;
}

If you want everything in your post to be as $Variables you can use something like this:

foreach($_POST as $key => $value) { eval("$" . $key . " = " . $value"); }

You can use nircmd.exe's elevate command

NirCmd Command Reference - elevate

elevate [Program] {Command-Line Parameters}

For Windows Vista/7/2008 only: Run a program with administrator rights. When the [Program] contains one or more space characters, you must put it in quotes.

Examples:

elevate notepad.exe 
elevate notepad.exe C:\Windows\System32\Drivers\etc\HOSTS 
elevate "c:\program files\my software\abc.exe"

PS: I use it on win 10 and it works

The below code is working,

<style>
    .PanelFloat {
        position: fixed;
        overflow: hidden;
        z-index: 2400;
        opacity: 0.70;
        right: 30px;
        top: 0px !important;
        -webkit-transition: all 0.5s ease-in-out;
        -moz-transition: all 0.5s ease-in-out;
        -ms-transition: all 0.5s ease-in-out;
        -o-transition: all 0.5s ease-in-out;
        transition: all 0.5s ease-in-out;
    }
</style>

<script>
 //The below script will keep the panel float on normal state
 $(function () {
        $(document).on('scroll', function () {
            //Multiplication value shall be changed based on user window
            $('#MyFloatPanel').css('top', 4 * ($(window).scrollTop() / 5));
        });
    });
 //To make the panel float over a bootstrap model which has z-index: 2300, so i specified custom value as 2400
 $(document).on('click', '.btnSearchView', function () {
      $('#MyFloatPanel').addClass('PanelFloat');
  });

  $(document).on('click', '.btnSearchClose', function () {
      $('#MyFloatPanel').removeClass('PanelFloat');
  });
 </script>

 <div class="col-lg-12 col-md-12">
   <div class="col-lg-8 col-md-8" >
    //My scrollable content is here
   </div>
   //This below panel will float while scrolling the above div content
   <div class="col-lg-4 col-md-4" id="MyFloatPanel">
    <div class="row">
     <div class="panel panel-default">
      <div class="panel-heading">Panel Head </div>
     <div class="panel-body ">//Your panel content</div>
   </div>
  </div>
 </div>
</div>

If you want only letters - so from a to z, lower case or upper case, excluding everything else (numbers, blank spaces, symbols), you can modify your function like this:

function validate() {
    if (document.myForm.name.value == "") {
        alert("Enter a name");
        document.myForm.name.focus();
        return false;
    }
    if (!/^[a-zA-Z]*$/g.test(document.myForm.name.value)) {
        alert("Invalid characters");
        document.myForm.name.focus();
        return false;
    }
}

This is the more powerful grouping / rollup syntax you'll want to use in SQL Server 2008+. Always useful to specify the version you're using so we don't have to guess.

SELECT 
  [Type] = COALESCE([Type], 'Total'), 
  [Total Sales] = SUM([Total Sales])
FROM dbo.Before
GROUP BY GROUPING SETS(([Type]),());

Craig Freedman wrote a great blog post introducing GROUPING SETS.

My objective was to create a new Django project from the command line in Ubuntu, like so:

django-admin.py startproject mysite

I have python2.7.5 installed. I got this error:

ImportError: No module named zlib

For hours I could not find a solution, until now!

Here is a link to the solution -

http://doc.biblissima-condorcet.fr/loris-setup-guide-ubuntu-debian

I followed and executed instruction in Section 1.1 and it is working perfectly! It is an easy solution.

I'm a Ubuntu user and I had the same issue, when I was trying to run python script through a bash script while files were located in a NTFS partition (even with su didn't work) then I've moved it home (ext4) then it worked.

Even if no convention is specified about this, manual references are consistently named after the referenced collection in the Mongo documentation, for one-to-one relations. The name always follows the structure <document>_id.

For example, in a dogs collection, a document would have manual references to external documents named like this:

{
  name: 'fido',
  owner_id: '5358e4249611f4a65e3068ab',
  race_id: '5358ee549611f4a65e3068ac',
  colour: 'yellow'
  ...

This follows the Mongo convention of naming _id the identifier for every document.

In my case i had few things missing. I didnt install JDK and JRE of 64 bit while eclipse was of 64 bit version. Once done and JDK\bin path was set in PATH variable eclipse worked fine :)

From a sqlite prompt:

sqlite> .read db.sql

Or:

cat db.sql | sqlite3 database.db

Also, your SQL is invalid - you need ; on the end of your statements:

create table server(name varchar(50),ipaddress varchar(15),id init);
create table client(name varchar(50),ipaddress varchar(15),id init);

Use the pandas.DataFrame.astype(<type>) function to manipulate column dtypes.

>>> df = pd.DataFrame(np.random.rand(3,4), columns=list("ABCD"))
>>> df

1  0.068542  0.757775  0.891903  0.384542
2  0.021274  0.587504  0.180426  0.574300
>>> df[list("ABCD")] = df[list("ABCD")].astype(int)
>>> df
   A  B  C  D
0  0  0  0  0

2  0  0  0  0

EDIT:

To handle missing values:

You are correct that ** is the power function.

^ is bitwise XOR.

% is indeed the modulus operation, but note that for positive numbers, x % m = x whenever m > x. This follows from the definition of modulus. (Additionally, Python specifies x % m to have the sign of m.)

// is a division operation that returns an integer by discarding the remainder. This is the standard form of division using the / in most programming languages. However, Python 3 changed the behavior of / to perform floating-point division even if the arguments are integers. The // operator was introduced in Python 2.6 and Python 3 to provide an integer-division operator that would behave consistently between Python 2 and Python 3. This means:

| context                                | `/` behavior   | `//` behavior |
---------------------------------------------------------------------------
| floating-point arguments, Python 2 & 3 | float division | int divison   |
---------------------------------------------------------------------------
| integer arguments, python 2            | int division   | int division  |
---------------------------------------------------------------------------
| integer arguments, python 3            | float division | int division  |

For more details, see this question: Division in Python 2.7. and 3.3

You are missing the std namespace reference in the cc file. You should also call nom.c_str() because there is no implicit conversion from std::string to const char * expected by ifstream's constructor.

Polygone::Polygone(std::string nom) {
    std::ifstream fichier (nom.c_str(), std::ifstream::in);
    // ...
}

Note that you can also hit this error if you accidentally type:

#define <stdio.h>

...instead of...

#include <stdio.>

In 2021 you should install wrapper:

ansible-galaxy collection install ansible.posix

And use

- name: Synchronize two directories on one remote host.
  ansible.posix.synchronize:
    src: /first/absolute/path
    dest: /second/absolute/path
  delegate_to: "{{ inventory_hostname }}"

So, simplejson.loads takes a json string and returns a data structure, which is why you are getting that type error there.

simplejson.dumps(data) comes back with

'[["apple", "cat"], ["banana", "dog"], ["pear", "fish"]]'

Which is a json array, which is what you want, since you gave this a python array.

If you want to get an "object" type syntax you would instead do

>>> data2 = {'apple':'cat', 'banana':'dog', 'pear':'fish'}
>>> simplejson.dumps(data2)
'{"pear": "fish", "apple": "cat", "banana": "dog"}'

which is javascript will come out as an object.

first use this:

LayoutInflater inflater = (LayoutInflater) Read_file.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

Read file is current activity in which you want your context.

View layout = inflater.inflate(R.layout.your_layout_name,(ViewGroup)findViewById(R.id.layout_name_id));

then you can use this to find any element in layout.

ImageView myImage = (ImageView) layout.findViewById(R.id.my_image);

just give your height and You will get height or even width if wanted.

/** * Get the view height before the view will render * @param view the view to measure * @return the height of the view */

public static int getViewHeight(View view) {
    WindowManager wm =
            (WindowManager) view.getContext().getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();

    int deviceWidth;

    if(android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2){
        Point size = new Point();
        display.getSize(size);
        deviceWidth = size.x;
    } else {
        deviceWidth = display.getWidth();
    }

    int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(deviceWidth, View.MeasureSpec.AT_MOST);
    int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
    view.measure(widthMeasureSpec, heightMeasureSpec);
    return view.getMeasuredHeight(); //        view.getMeasuredWidth();
}

class Foo(object):    
    bar = 1

    def bah(object_reference):
        object_reference.var = Foo.bar
        return object_reference.var


f = Foo() 
print 'var=', f.bah()

What you should do, is put CallFunction into *.cpp file, where you include B.h.

After edit, files will look like:

B.h:

#pragma once //or other specific to compiler...
using namespace std;

class A 
{
public:
    void CallFunction ();
};

class B: public A
{
public:
    virtual void bFunction()
        {
            //stuff done here
        }
};

B.cpp

#include "B.h"
void A::CallFunction(){
//use B object here...
}

Referencing to your explanation, that you have tried to change B b; into pointer- it would be okay, if you wouldn't use it in that same place. You can use pointer of undefined class(but declared), because ALL pointers have fixed byte size(4), so compiler doesn't have problems with that. But it knows nothing about the object they are pointing to(simply: knows the size/boundary, not the content).

So as long as you are using the knowledge, that all pointers are same size, you can use them anywhere. But if you want to use the object, they are pointing to, the class of this object must be already defined and known by compiler.

And last clarification: objects may differ in size, unlike pointers. Pointer is a number/index, which indicates the place in RAM, where something is stored(for example index: 0xf6a7b1).

1.Install-Package Microsoft.AspNet.WebApi.Cors

2 . Add this code in WebApiConfig.cs.

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services

    // Web API routes

    config.EnableCors();

    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );
}

3. Add this

using System.Web.Http.Cors; 

4. Add this code in Api Controller (HomeController.cs)

[EnableCors(origins: "*", headers: "*", methods: "*")]
public class HomeController : ApiController
{
    [HttpGet]
    [Route("api/Home/test")]
    public string test()
    {
       return "";
    }
}

While jkp's solution works, the newer way of doing things (and the way the documentation recommends) is to use the subprocess module. For simple commands its equivalent, but it offers more options if you want to do something complicated.

Example for your case:

import subprocess
subprocess.Popen(["rm","-r","some.file"])

This will run rm -r some.file in the background. Note that calling .communicate() on the object returned from Popen will block until it completes, so don't do that if you want it to run in the background:

import subprocess
ls_output=subprocess.Popen(["sleep", "30"])
ls_output.communicate()  # Will block for 30 seconds

See the documentation here.

Also, a point of clarification: "Background" as you use it here is purely a shell concept; technically, what you mean is that you want to spawn a process without blocking while you wait for it to complete. However, I've used "background" here to refer to shell-background-like behavior.

Answering this because I trapped myself with it by now knowing this and maybe it will be useful.

Keep in mind that you cant fetch results twice. You have to save fetch result into array, get row count by count($array), and output results with foreach. For example:

$query = "your_query_here";
$STH = $DBH->prepare($query);
$STH->execute();
$rows = $STH->fetchAll();
//all your results is in $rows array
$STH->setFetchMode(PDO::FETCH_ASSOC);           
if (count($rows) > 0) {             
    foreach ($rows as $row) {
        //output your rows
    }                       
}

Also, one things that may help to understand:

math.js

this.add = function (a, b) {
    return a + b;
};

client.js

var math = require('./math');
console.log(math.add(2,2); // 4;

Great, in this case:

console.log(this === module.exports); // true
console.log(this === exports); // true
console.log(module.exports === exports); // true

Thus, by default, "this" is actually equals to module.exports.

However, if you change your implementation to:

math.js

var add = function (a, b) {
    return a + b;
};

module.exports = {
    add: add
};

In this case, it will work fine, however, "this" is not equal to module.exports anymore, because a new object was created.

console.log(this === module.exports); // false
console.log(this === exports); // true
console.log(module.exports === exports); // false

And now, what will be returned by the require is what was defined inside the module.exports, not this or exports, anymore.

Another way to do it would be:

math.js

module.exports.add = function (a, b) {
    return a + b;
};

Or:

math.js

exports.add = function (a, b) {
    return a + b;
};

You can check in windows services if tomcat is installed it will be listed in windows services.

To check the windows service list of services installed on windows machine use

  WINDOWS KEY + R   and type services.msc

There you can find all the services related with Jasperreport server like Tomcat and MySQL with name starting Jasperreport server Tomcat and MySQL only if these services are installed and its need to be started by selecting the option.Then you can access it through browser using this link :-

   http://localhost:8080

default port for tomcat is 8080.

Xcode 8.2.1 • Swift 3.0.2

extension Date {
    var hour: Int { return Calendar.autoupdatingCurrent.component(.hour, from: self) }
}

let date = Date()      // "Mar 16, 2017, 3:43 PM"
let hour = date.hour   // 15

In pyspark 2.4 onwards, you can simply use header parameter to set the correct header:

data = spark.read.csv('data.csv', header=True)

Similarly, if using scala you can use header parameter as well.

Convert an ArrayList to an object array

ArrayList has a constructor that takes a Collection, so the common idiom is:

List<T> list = new ArrayList<T>(Arrays.asList(array));

Which constructs a copy of the list created by the array.

now, Arrays.asList(array) will wrap the array, so changes to the list will affect the array, and visa versa. Although you can't add or remove

elements from such a list.

For Bootstrap v4.0.0 beta release you will need the following added to a stylesheet that overrides Bootstrap (either add in after CDN/local link to bootstrap v4.0.0 beta or add !important to the stylings:

.form-control:focus {
  border-color: #6265e4 !important;
  box-shadow: 0 0 5px rgba(98, 101, 228, 1) !important;
}

Replace the border-color and the rgba on the box-shadow with which ever colour style you'd like*.

As Collectors.toMap(keyMapper, valueMapper) uses a throwing merger to handle multiple entries with the same key it is easy:

List<User> users = new LinkedList<>();
users.add(new User(1, "User1"));
users.add(new User(2, "User2"));
users.add(new User(3, "User3"));

int id = 1;
User match = Optional.ofNullable(users.stream()
  .filter(user -> user.getId() == id)
  .collect(Collectors.toMap(User::getId, Function.identity()))
  .get(id)).get();

You will get a IllegalStateException for duplicate keys. But at the end I am not sure if the code would not be even more readable using an if.

First you need to start karma server with

karma start

Then, you can use grep to filter a specific test or describe block:

karma run -- --grep=testDescriptionFilter

The quoting rules are painful. I think you want:

SELECT nextval('foo."SQ_ID"');

to prevent case-folding of SQ_ID.

If globally installed then

"scripts": {
    "start": "nodemon FileName.js(server.js)",
},

Make sure you have installed nodemon globally:

npm install -g nodemon

Finally, if you are a Windows user, make sure that the security restriction of the Windows PowerShell is enabled.

Here's another native PHP based option: https://github.com/2createStudio/shuttle-export

Your first example is effectively what you need:

<TextBlock Text="{Binding CelsiusTemp, StringFormat={}{0}°C}" />

Here is my simple solution:

1 - Define your fragment

public class MyFragment extends Fragment {

    private String parameter;

    public MyFragment() {
    }

    public void setParameter(String parameter) {
        this.parameter = parameter;
    } 
}

2 - Create your new fragment and populate the parameter

    myfragment = new MyFragment();
    myfragment.setParameter("here the value of my parameter");

3 - Enjoy it!

Obviously you can change the type and the number of parameters. Quick and easy.

public static JSONObject updateJson(JSONObject obj, String keyString, String newValue) throws Exception {
            JSONObject json = new JSONObject();
            // get the keys of json object
            Iterator iterator = obj.keys();
            String key = null;
            while (iterator.hasNext()) {
                key = (String) iterator.next();
                // if the key is a string, then update the value
                if ((obj.optJSONArray(key) == null) && (obj.optJSONObject(key) == null)) {
                    if ((key.equals(keyString))) {
                        // put new value
                        obj.put(key, newValue);
                        return obj;
                    }
                }

                // if it's jsonobject
                if (obj.optJSONObject(key) != null) {
                    updateJson(obj.getJSONObject(key), keyString, newValue);
                }

                // if it's jsonarray
                if (obj.optJSONArray(key) != null) {
                    JSONArray jArray = obj.getJSONArray(key);
                    for (int i = 0; i < jArray.length(); i++) {
                        updateJson(jArray.getJSONObject(i), keyString, newValue);
                    }
                }
            }
            return obj;
        }

Here is a very simple way:

<asp:ButtonField ButtonType="Button" CommandName="Edit" Text="Edit" Visible="True" 
                 CommandArgument='<%# Container.DataItemIndex %>' />

in support libraries you always need to add three numbers as version number

Suppose for 22 -> you need to write it as 22.0.0, not just 22

for 22.1 -> 22.1.0

So your dependencies should look like this

compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.android.support:support-v4:22.0.0'
compile 'com.android.support:cardview-v7:22.0.0'
compile 'com.android.support:recyclerview-v7:22.0.0'

I Programmers language you need to pad extra zeros.

Hope this solves your problem

In your example problem is passed table name pattern in getTables function of DatabaseMetaData.

Some database supports Uppercase identifier, some support lower case identifiers. For example oracle fetches the table name in upper case, while postgreSQL fetch it in lower case.

DatabaseMetaDeta provides a method to determine how the database stores identifiers, can be mixed case, uppercase, lowercase see:http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#storesMixedCaseIdentifiers()

From below example, you can get all tables and view of providing table name pattern, if you want only tables then remove "VIEW" from TYPES array.

public class DBUtility {
    private static final String[] TYPES = {"TABLE", "VIEW"};
    public static void getTableMetadata(Connection jdbcConnection, String tableNamePattern, String schema, String catalog, boolean isQuoted) throws HibernateException {
            try {
                DatabaseMetaData meta = jdbcConnection.getMetaData();
                ResultSet rs = null;
                try {
                    if ( (isQuoted && meta.storesMixedCaseQuotedIdentifiers())) {
                        rs = meta.getTables(catalog, schema, tableNamePattern, TYPES);
                    } else if ( (isQuoted && meta.storesUpperCaseQuotedIdentifiers())
                        || (!isQuoted && meta.storesUpperCaseIdentifiers() )) {
                        rs = meta.getTables(
                                StringHelper.toUpperCase(catalog),
                                StringHelper.toUpperCase(schema),
                                StringHelper.toUpperCase(tableNamePattern),
                                TYPES
                            );
                    }
                    else if ( (isQuoted && meta.storesLowerCaseQuotedIdentifiers())
                            || (!isQuoted && meta.storesLowerCaseIdentifiers() )) {
                        rs = meta.getTables( 
                                StringHelper.toLowerCase( catalog ),
                                StringHelper.toLowerCase(schema), 
                                StringHelper.toLowerCase(tableNamePattern), 
                                TYPES 
                            );
                    }
                    else {
                        rs = meta.getTables(catalog, schema, tableNamePattern, TYPES);
                    }

                    while ( rs.next() ) {
                        String tableName = rs.getString("TABLE_NAME");
                        System.out.println("table = " + tableName);

Make sure the PNGs are fully opaque before creating the video

e.g. with imagemagick, give them a black background:

convert 0.png -background black -flatten +matte 0_opaque.png

From my tests, no bitrate or codec is sufficient to make the video look good if you feed ffmpeg PNGs with transparency

Yes, Python does support Short-circuit evaluation, minimal evaluation, or McCarthy evaluation for Boolean operators. It is used to reduce the number of evaluations for computing the output of boolean expression. Example -

Base Functions

def a(x):
    print('a')
    return x

def b(x):
    print('b')
    return x 

AND

if(a(True) and b(True)):
    print(1,end='\n\n')

if(a(False) and b(True)):
    print(2,end='\n\n') 

AND-OUTPUT

a
b
1

a 

OR

if(a(True) or b(False)):
    print(3,end='\n\n')

if(a(False) or b(True)):
    print(4,end='\n\n') 

OR-OUTPUT

a
3

a
b
4 

If you want to keep the innerHTML of the element and only strip the outermost tag, you can do this:

$(".contentToStrip").each(function(){
  $(this).replaceWith($(this).html());
});

You've correctly identified the problem when you said "... for the AlertDialog() neither getApplicationContext() or getApplication() is acceptable as a Context, as it throws the exception: 'Unable to add window — token null is not for an application'"

To create a Dialog, you need an Activity Context or a Service Context, not an Application Context (both getApplicationContext() and getApplication() return an Application Context).

Here's how you get the Activity Context:

(1) In an Activity or a Service:

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

(2) In a Fragment: AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

Memory leaks is not a problem that is intrinsic to the "this" reference, which is an object's reference to itself (i.e. reference to the actual allocated memory for storing the object's data). It happens to any allocated memory for which the Garbage Collector (GC) is unable to free up after the allocated memory has outlived its useful lifespan.

Most of the time, when a variable goes out of scope, the memory will be reclaimed by the GC. However, memory leaks can occur when the reference to an object held by a variable, say "x", persists even after the object has outlived its useful lifespan. The allocated memory will hence be lost for as long as "x" holds a reference to it because GC will not free up the memory for as long as that memory is still being referenced. Sometimes, memory leaks are not apparent because of a chain of references to the allocated memory. In such a case, the GC will not free up the memory until all references to that memory have been removed.

To prevent memory leaks, check your code for logical errors that cause allocated memory to be referenced indefinitely by "this" (or other references). Remember to check for chain references as well. Here are some tools you can use to help you analyze memory use and find those pesky memory leaks:

• JRockit Mission Control

• JProbe

• YourKit

• AD4J

To answer the question whether there is any caching going on.

I investigated this point further by running a stand-alone Java application that continuously loaded a file from disk using the getResourceAsStream ClassLoader method. I was able to edit the file, and the changes were reflected immediately, i.e., the file was reloaded from disk without caching.

However: I'm working on a project with several maven modules and web projects that have dependencies on each other. I'm using IntelliJ as my IDE to compile and run the web projects.

I noticed that the above seemed to no longer hold true, the reason being that the file that I was being loaded is now baked into a jar and deployed to the depending web project. I only noticed this after trying to change the file in my target folder, to no avail. This made it seem as though there was caching going on.

You didn't close the file after creating it, so when you write to it, it's in use by yourself. The Create method opens the file and returns a FileStream object. You either write to the file using the FileStream or close it before writing to it. I would suggest that you use the CreateText method instead in this case, as it returns a StreamWriter.

You also forgot to close the StreamWriter in the case where the file didn't exist, so it would most likely still be locked when you would try to write to it the next time. And you forgot to write the error message to the file if it didn't exist.

Dim strFile As String = "C:\ErrorLog_" & DateTime.Today.ToString("dd-MMM-yyyy") & ".txt"
Dim sw As StreamWriter
Try
   If (Not File.Exists(strFile)) Then
      sw = File.CreateText(strFile)
      sw.WriteLine("Start Error Log for today")
   Else
      sw = File.AppendText(strFile)
   End If
   sw.WriteLine("Error Message in  Occured at-- " & DateTime.Now)
   sw.Close()
Catch ex As IOException
   MsgBox("Error writing to log file.")
End Try

Note: When you catch exceptions, don't catch the base class Exception, catch only the ones that are releveant. In this case it would be the ones inheriting from IOException.

A small change of cgnorthcutt's solution, considering the string type variables

def get_confusion_matrix(l1, l2):

    assert len(l1)==len(l2), "Two lists have different size."

    K = len(np.unique(l1))

    # create label-index value
    label_index = dict(zip(np.unique(l1), np.arange(K)))

    result = np.zeros((K, K))
    for i in range(len(l1)):
        result[label_index[l1[i]]][label_index[l2[i]]] += 1

    return result

UPDATED:
Matt provided a great link on how to add emulators for all Samsung devices.

OLD:
To get the official Samsung Galaxy Tab emulator do the following:

1. Open the Android SDK and AVD Manager
2. Click on Available packages
3. Expand the Third party Add-ons. There you will see Samsung Electronics add-ons.
4. Once the add-on is installed create a new emulator. Under Target you will see the new Samsung Tab settings, select that.

That's it!

You only need to delete one folder it is throwing error for. Just go to your M2 repo and org/apache/maven/plugins/maven-compiler-plugins and delete the folder 2.3.2

addItem(Object) takes an object. The default JComboBox renderer calls toString() on that object and that's what it shows as the label.

So, don't pass in a String to addItem(). Pass in an object whose toString() method returns the label you want. The object can contain any number of other data fields also.

Try passing this into your combobox and see how it renders. getSelectedItem() will return the object, which you can cast back to Widget to get the value from.

public final class Widget {
    private final int value;
    private final String label;

    public Widget(int value, String label) {
        this.value = value;
        this.label = label;
    }

    public int getValue() {
        return this.value;
    }

    public String toString() {
        return this.label;
    }
}

I started getting this error after converting my project into a typescript project. From what I understand, the problem stems from async/await not being recognized.

For me the error was fixed by adding two things to my setup:

1. As mentioned above many times, I needed to add babel-polyfill into my webpack entry array:

   ...
   
   entry: ['babel-polyfill', './index.js'],
   
   ...

2. I needed to update my .babelrc to allow the complilation of async/await into generators:

   {
     "presets": ["es2015"],
     "plugins": ["transform-async-to-generator"]
   }

DevDependencies:

I had to install a few things into my devDependencies in my package.json file as well. Namely, I was missing the babel-plugin-transform-async-to-generator, babel-polyfill and the babel-preset-es2015:

 "devDependencies": {
    "babel-loader": "^6.2.2",
    "babel-plugin-transform-async-to-generator": "^6.5.0",
    "babel-polyfill": "^6.5.0",
    "babel-preset-es2015": "^6.5.0",
    "webpack": "^1.12.13"
 }

Full Code Gist:

I got the code from a really helpful and concise GitHub gist you can find here.

I use maven for my java builds which has a plugin called the maven assembly plugin.

It does what your asking, but like some of the other suggestions describe - essentially exploding all the dependent jars and recombining them into a single jar

The problem is that the user in the database is an "orphan". This means that there is no login id or password associated with the user. This is true even if there is a login id that matches the user, since there is a GUID (called a SID in Microsoft-speak) that has to match as well.

This used to be a pain to fix, but currently (SQL Server 2000, SP3) there is a stored procedure that does the heavy lifting.

All of these instructions should be done as a database admin, with the restored database selected.

First, make sure that this is the problem. This will lists the orphaned users:

EXEC sp_change_users_login 'Report'

If you already have a login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'Auto_Fix', 'user'

If you want to create a new login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'

The error indicates that the DLL is either not a COM DLL or it's corrupt. If it's not a COM DLL and not being used as a COM DLL by an application then there is no need to register it.
From what you say in your question (the service is not registered) it seems that we are talking about a service not correctly installed. I will try to reinstall the application.

Probably not the dictionary definition, but a callback usually refers to a function, which is external to a particular object, being stored and then called upon a specific event.

An example might be when a UI button is created, it stores a reference to a function which performs an action. The action is handled by a different part of the code but when the button is pressed, the callback is called and this invokes the action to perform.

C#, rather than use the term 'callback' uses 'events' and 'delegates' and you can find out more about delegates here.

I'm pretty sure you can't simply add on delete cascade to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to

• start a transaction,
• drop the foreign key,
• add a foreign key with on delete cascade, and finally
• commit the transaction

Repeat for each foreign key you want to change.

But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example

alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
   foreign key (gid)
   references games(gid)
   on delete cascade;

If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.

select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null

You can read the Name from WindowsIdentity:

var user = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
return Ok(user);

There may be an elegant built-in function (but I haven't found it yet). You could write one:

# reorder columns
def set_column_sequence(dataframe, seq, front=True):
    '''Takes a dataframe and a subsequence of its columns,
       returns dataframe with seq as first columns if "front" is True,
       and seq as last columns if "front" is False.
    '''
    cols = seq[:] # copy so we don't mutate seq
    for x in dataframe.columns:
        if x not in cols:
            if front: #we want "seq" to be in the front
                #so append current column to the end of the list
                cols.append(x)
            else:
                #we want "seq" to be last, so insert this
                #column in the front of the new column list
                #"cols" we are building:
                cols.insert(0, x)
return dataframe[cols]

For your example: set_column_sequence(df, ['x','y']) would return the desired output.

If you want the seq at the end of the DataFrame instead simply pass in "front=False".

Time has moved on and since version 2 Ruby supports named parameters:

def ldap_get ( base_dn, filter, scope: "some_scope", attrs: nil )
  p attrs
end

ldap_get("first_arg", "second_arg", attrs: "attr1, attr2") # => "attr1, attr2"

The problem seems to be in the way how ng-model works with input and overwrites the name object, making it lost for ng-repeat.

As a workaround, one can use the following code:

<div ng-repeat="name in names">
    Value: {{name}}
    <input ng-model="names[$index]">                         
</div>

Hope it helps

your div looks like this:

<div id="someId">Some Value</div>

With jquery:

   <script type="text/javascript">
     $(function(){
         var text = $('#someId').html(); 
         //or
         var text = $('#someId').text();
       };
  </script> 

JavaScript Array splice() Method By Example

Example1 by tutsmake -Remove 2 elements from index 1

  var arr = [ "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten" ]; 

 arr.splice(1,2);

 console.log( arr ); 

Example-2 By tutsmake – Add new element from index 0 JavaScript

  var arr = [ "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten" ]; 

 arr.splice(0,0,"zero");

 console.log( arr );  

Example-3 by tutsmake – Add and Remove Elements in Array JavaScript

var months = ['Jan', 'March', 'April', 'June'];

months.splice(1, 0, 'Feb'); // add at index 1

console.log(months); 

months.splice(4, 1, 'May'); // replaces 1 element at index 4

console.log(months);

Reasons of ignoring these argument is permanent generation has been removed in HotSpot for JDK8 because of following drawbacks

• Fixed size at startup – difficult to tune.
• Internal Hotspot types were Java objects : Could move with full GC, opaque, not strongly typed and hard to debug, needed meta-metadata.
• Simplify full collections : Special iterators for metadata for each collector
• Want to deallocate class data concurrently and not during GC pause
• Enable future improvements that were limited by PermGen.

The Permanent Generation (PermGen) space has completely been removed and is kind of replaced by a new space called Metaspace. The consequences of the PermGen removal is that obviously the PermSize and MaxPermSize JVM arguments are ignored and you will never get a java.lang.OutOfMemoryError: PermGen error.

Advantages of MetaSpace

• Take advantage of Java Language Specification property : Classes and associated metadata lifetimes match class loader’s
• Per loader storage area – Metaspace
• Linear allocation only
• No individual reclamation (except for RedefineClasses and class loading failure)
• No GC scan or compaction
• No relocation for metaspace objects

Metaspace Tuning

The maximum metaspace size can be set using the -XX:MaxMetaspaceSize flag, and the default is unlimited, which means that only your system memory is the limit. The -XX:MetaspaceSize tuning flag defines the initial size of metaspace If you don’t specify this flag, the Metaspace will dynamically re-size depending of the application demand at runtime.

Change enables other optimizations and features in the future

• Application class data sharing
• Young collection optimizations, G1 class unloading
• Metadata size reductions and internal JVM footprint projects

There is improved GC performace also.

>>> import ast
>>> x = '[ "A","B","C" , " D"]'
>>> x = ast.literal_eval(x)
>>> x
['A', 'B', 'C', ' D']
>>> x = [n.strip() for n in x]
>>> x
['A', 'B', 'C', 'D']

ast.literal_eval:

With ast.literal_eval you can safely evaluate an expression node or a string containing a Python literal or container display. The string or node provided may only consist of the following Python literal structures: strings, bytes, numbers, tuples, lists, dicts, booleans, and None.

As for the inverse, the function is inv(A), but I won't recommend using it, since for huge matrices it is very computationally costly and unstable. Instead, you should use an approximation to the inverse, or if you want to solve Ax = b you don't really need A^-1.

You can make use of history.listen() function when trying to detect the route change. Considering you are using react-router v4, wrap your component with withRouter HOC to get access to the history prop.

history.listen() returns an unlisten function. You'd use this to unregister from listening.

You can configure your routes like

index.js

ReactDOM.render(
      <BrowserRouter>
            <AppContainer>
                   <Route exact path="/" Component={...} />
                   <Route exact path="/Home" Component={...} />
           </AppContainer>
        </BrowserRouter>,
  document.getElementById('root')
);

and then in AppContainer.js

class App extends Component {
  
  componentWillMount() {
    this.unlisten = this.props.history.listen((location, action) => {
      console.log("on route change");
    });
  }
  componentWillUnmount() {
      this.unlisten();
  }
  render() {
     return (
         <div>{this.props.children}</div>
      );
  }
}
export default withRouter(App);

From the history docs:

You can listen for changes to the current location using history.listen:

history.listen((location, action) => {
      console.log(`The current URL is ${location.pathname}${location.search}${location.hash}`)
  console.log(`The last navigation action was ${action}`)
})

The location object implements a subset of the window.location interface, including:

**location.pathname** - The path of the URL
**location.search** - The URL query string
**location.hash** - The URL hash fragment

Locations may also have the following properties:

location.state - Some extra state for this location that does not reside in the URL (supported in createBrowserHistory and createMemoryHistory)

location.key - A unique string representing this location (supported in createBrowserHistory and createMemoryHistory)

The action is one of PUSH, REPLACE, or POP depending on how the user got to the current URL.

When you are using react-router v3 you can make use of history.listen() from history package as mentioned above or you can also make use browserHistory.listen()

You can configure and use your routes like

import {browserHistory} from 'react-router';

class App extends React.Component {

    componentDidMount() {
          this.unlisten = browserHistory.listen( location =>  {
                console.log('route changes');
                
           });
      
    }
    componentWillUnmount() {
        this.unlisten();
     
    }
    render() {
        return (
               <Route path="/" onChange={yourHandler} component={AppContainer}>
                   <IndexRoute component={StaticContainer}  />
                   <Route path="/a" component={ContainerA}  />
                   <Route path="/b" component={ContainerB}  />
            </Route>
        )
    }
} 

This is due to IFS (Internal Field Separator) variable which contains newline.

$ cat xx1
1
2

$ A=`cat xx1`
$ echo $A
1 2

$ echo "|$IFS|"
|       
|

A workaround is to reset IFS to not contain the newline, temporarily:

$ IFSBAK=$IFS
$ IFS=" "
$ A=`cat xx1` # Can use $() as well
$ echo $A
1
2
$ IFS=$IFSBAK

To REVERT this horrible change for IFS:

IFS=$IFSBAK

1. Check for all js files, the order should be maintained.
2. The order should be maintained as

    -> jquery.min.js
    -> bootstrap.min.js
    -> any external js files

Design Patterns in Dynamic Programming by Peter Norvig has thoughtful coverage of this general theme, though about 'dynamic' languages instead of 'functional' (there's overlap).

If you are able to use org.apache.commons.lang.StringUtils, I suggest using the following:

String container = "aBcDeFg";
String content = "dE";
boolean containerContainsContent = StringUtils.containsIgnoreCase(container, content);

Yes you can; it works on Android too:

tel: phone_number
Calls the entered phone number. Valid telephone numbers as defined in the IETF RFC 3966 are accepted. Valid examples include the following:

* tel:2125551212
* tel: (212) 555 1212

The Android browser uses the Phone app to handle the “tel” scheme, as defined by RFC 3966.
Clicking a link like:

<a href="tel:2125551212">2125551212</a>

on Android will bring up the Phone app and pre-enter the digits for 2125551212 without autodialing.

Have a look to RFC3966

Try str.replace():

string = "it is icy"
print string.replace("i", "")

Declare an instance of the CBetfairAPI class or make it static.

you have done it the correct way using

curl_setopt($ch, CURLOPT_POSTFIELDS,$body);

but i notice your missing

curl_setopt($ch, CURLOPT_POST,1);

Knowing how to write a preset dictionary is useful to know as well:

cmap =  {'US':'USA','GB':'Great Britain'}

# Explicitly:
# -----------
def cxlate(country):
    try:
        ret = cmap[country]
    except KeyError:
        ret = '?'
    return ret

present = 'US' # this one is in the dict
missing = 'RU' # this one is not

print cxlate(present) # == USA
print cxlate(missing) # == ?

# or, much more simply as suggested below:

print cmap.get(present,'?') # == USA
print cmap.get(missing,'?') # == ?

# with country codes, you might prefer to return the original on failure:

print cmap.get(present,present) # == USA
print cmap.get(missing,missing) # == RU

If you need exact your example, you should add format to ToString()

    string test = DateTime.ParseExact(DateTime.Now.ToString("dd.MM.yyyy"), "dd.MM.yyyy", CultureInfo.InvariantCulture).ToString("yyyy-MM-dd");

But it's better to use straight formatting:

    string test = DateTime.Now.ToString("yyyy-MM-dd")

@skaffman nailed it down. They live each in its own context. However, I wouldn't consider using scriptlets as the solution. You'd like to avoid them. If all you want is to concatenate strings in EL and you discovered that the + operator fails for strings in EL (which is correct), then just do:

<c:out value="abc${test}" />

Or if abc is to obtained from another scoped variable named ${resp}, then do:

<c:out value="${resp}${test}" />

No need to use regex .... Just use list slicing ...

string="(tidtkdgkxkxlgxlhxl) ¥£%#_¥#_¥#_¥#"
print(string[string.find("(")+1:string.find(")")])

Check out the CPAN module Regexp::Common. I think it does exactly what you need and handles all the edge cases (e.g. real numbers, scientific notation, etc). e.g.

use Regexp::Common;
if ($var =~ /$RE{num}{real}/) { print q{a number}; }

You can skip the ORM, builders, etc. and simplify your DB/SQL management using sqler and sqler-mdb.

-- create this file at: db/mdb/setup/create.database.sql
CREATE DATABASE IF NOT EXISTS sqlermysql

const conf = {
  "univ": {
    "db": {
      "mdb": {
        "host": "localhost",
        "username":"admin",
        "password": "mysqlpassword"
      }
    }
  },
  "db": {
    "dialects": {
      "mdb": "sqler-mdb"
    },
    "connections": [
      {
        "id": "mdb",
        "name": "mdb",
        "dir": "db/mdb",
        "service": "MySQL",
        "dialect": "mdb",
        "pool": {},
        "driverOptions": {
          "connection": {
            "multipleStatements": true
          }
        }
      }
    ]
  }
};

// create/initialize manager
const manager = new Manager(conf);
await manager.init();

// .sql file path is path to db function
const result = await manager.db.mdb.setup.create.database();

console.log('Result:', result);

// after we're done using the manager we should close it
process.on('SIGINT', async function sigintDB() {
  await manager.close();
  console.log('Manager has been closed');
});

Your fundamental problem is that grep works one line at a time - so it cannot find a SELECT statement spread across lines.

Your second problem is that the regex you are using doesn't deal with the complexity of what can appear between SELECT and FROM - in particular, it omits commas, full stops (periods) and blanks, but also quotes and anything that can be inside a quoted string.

I would likely go with a Perl-based solution, having Perl read 'paragraphs' at a time and applying a regex to that. The downside is having to deal with the recursive search - there are modules to do that, of course, including the core module File::Find.

In outline, for a single file:

$/ = "\n\n";    # Paragraphs

while (<>)
{
     if ($_ =~ m/SELECT.*customerName.*FROM/mi)
     {
         printf file name
         go to next file
     }
}

That needs to be wrapped into a sub that is then invoked by the methods of File::Find.

I did not know that even with the "Allow Installation of non-Marked application", I still needed to sign the application.

I self-signed my application, following this link self-sign and release application, It only took 5 minutes, then I emailed the signed-APK file to myself and downloaded it to SD-card and then installed it without any problem.

This is not a direct answer to OP's question, this is more of the stuffs (experiments) I tried so far to solve the same problem and obtained some results and have some observations that I want to share, I am curious if we can have some further insights from this.

I just tried my minimax implementation with alpha-beta pruning with search-tree depth cutoff at 3 and 5. I was trying to solve the same problem for a 4x4 grid as a project assignment for the edX course ColumbiaX: CSMM.101x Artificial Intelligence (AI).

I applied convex combination (tried different heuristic weights) of couple of heuristic evaluation functions, mainly from intuition and from the ones discussed above:

1. Monotonicity
2. Free Space Available

In my case, the computer player is completely random, but still i assumed adversarial settings and implemented the AI player agent as the max player.

I have 4x4 grid for playing the game.

Observation:

If I assign too much weights to the first heuristic function or the second heuristic function, both the cases the scores the AI player gets are low. I played with many possible weight assignments to the heuristic functions and take a convex combination, but very rarely the AI player is able to score 2048. Most of the times it either stops at 1024 or 512.

I also tried the corner heuristic, but for some reason it makes the results worse, any intuition why?

Also, I tried to increase the search depth cut-off from 3 to 5 (I can't increase it more since searching that space exceeds allowed time even with pruning) and added one more heuristic that looks at the values of adjacent tiles and gives more points if they are merge-able, but still I am not able to get 2048.

I think it will be better to use Expectimax instead of minimax, but still I want to solve this problem with minimax only and obtain high scores such as 2048 or 4096. I am not sure whether I am missing anything.

Any insights will be really very helpful, thanks in advance.

The following animation shows the last few steps of the game played where the AI player agent could get 2048 scores, this time adding the absolute value heuristic too:

The following figures show the game tree explored by the player AI agent assuming the computer as adversary for just a single step:

Rather than escaping all characters in a string that have particular significance in the pattern syntax given that you are using a leading wildcard in the pattern it is quicker and easier just to do.

SELECT * 
FROM YourTable
WHERE CHARINDEX(@myString , YourColumn) > 0

In cases where you are not using a leading wildcard the approach above should be avoided however as it cannot use an index on YourColumn.

Additionally in cases where the optimum execution plan will vary according to the number of matching rows the estimates may be better when using LIKE with the square bracket escaping syntax when compared to both CHARINDEX and the ESCAPE keyword.

if the name of your list is listlen then just type len(listlen). This will return the size of your list in the python.

A rewrite for easy reading:

# 2D array/ matrix

# 5 rows, 5 cols
rows_count = 5
cols_count = 5

# create
#     creation looks reverse
#     create an array of "cols_count" cols, for each of the "rows_count" rows
#        all elements are initialized to 0
two_d_array = [[0 for j in range(cols_count)] for i in range(rows_count)]

# index is from 0 to 4
#     for both rows & cols
#     since 5 rows, 5 cols

# use
two_d_array[0][0] = 1
print two_d_array[0][0]  # prints 1   # 1st row, 1st col (top-left element of matrix)

two_d_array[1][0] = 2
print two_d_array[1][0]  # prints 2   # 2nd row, 1st col

two_d_array[1][4] = 3
print two_d_array[1][4]  # prints 3   # 2nd row, last col

two_d_array[4][4] = 4
print two_d_array[4][4]  # prints 4   # last row, last col (right, bottom element of matrix)

Does it really have to be a thread, or can it be a task too?

if so, the easiest way is:

Task.Factory.StartNew(() => SecondFoo())

I came across this post and went back to an approach that I used some time ago which is similar to @MadAntrax's.

The main difference is that it uses a VBScript user-defined class to wrap all the logic for switching to CScript and outputting text to the console, so it makes the main script a bit cleaner.

This assumes that your objective is to stream output to the console, rather than having output go to message boxes.

The cCONSOLE class is below. To use it, include the complete class at the end of your script, and then instantiate it right at the beginning of the script. Here is an example:

    Option Explicit

'// Instantiate the console object, this automatically switches to CSCript if required
Dim CONS: Set CONS = New cCONSOLE

'// Now we can use the Consol object to write to and read from the console
With CONS

    '// Simply write a line
     .print "CSCRIPT Console demo script"

     '// Arguments are passed through correctly, if present
     .Print "Arg count=" & wscript.arguments.count

     '// List all the arguments on the console log
     dim ix
     for ix = 0 to wscript.arguments.count -1
        .print "Arg(" & ix & ")=" & wscript.arguments(ix)
     next

     '// Prompt for some text from the user
     dim sMsg : sMsg = .prompt( "Enter any text:" )

     '// Write out the text in a box
     .Box sMsg

     '// Pause with the message "Hit enter to continue"
     .Pause

End With

You can use the -B and -A to print lines before and after the match.

grep -i -B 10 'error' data

Will print the 10 lines before the match, including the matching line itself.

It also might be that you haven't declared you Dependency Injected service, as a provider in the component that you injected it to. That was my case :)

Check if exist, put all files in array, preg grep all JPG files, echo new array For all images could try this:

$images=preg_grep('/\.(jpg|jpeg|png|gif)(?:[\?\#].*)?$/i', $files);


if ($handle = opendir('/path/to/folder')) {

    while (false !== ($entry = readdir($handle))) {
        $files[] = $entry;
    }
    $images=preg_grep('/\.jpg$/i', $files);

    foreach($images as $image)
    {
    echo $image;
    }
    closedir($handle);
}

Use the below two commands one by one.

git gc --prune=now

git remote prune origin

This will resolve your issue.

This will be easy... its an pure javascript code

    <script>
           alert(document.getElementById("someElement").previousElementSibling.innerHTML);
    </script>

Its defined in RFC 2045 as a special padding character if fewer than 24 bits are available at the end of the encoded data.

Try This.

Controller:

List<CountryModel> countryList = db.countryTable.ToList();
ViewBag.Country = new SelectList(countryList, "Country", "CountryName");

I think you are talking about padding strings with spaces.

One way to do this is with string format codes.

For example, if you want to pad a string to a certain length with spaces, use something like this:

String padded = String.format("%-20s", str);

In a formatter, % introduces a format sequence. The - means that the string will be left-justified (spaces will be added on the right of the string). The 20 means the resulting string will be 20 characters long. The s is the character string format code, and ends the format sequence.

For installing Composer below steps worked me:(WAMP version 2.4 x64bit)

edit ->
**C:\wamp\bin\php\php5.4.12\php.ini**
;;uncomment below line or remove the semicolons ';'
extension=php_openssl.dll

**C:\wamp\bin\apache\Apache2.4.4\bin\php.ini**

extension=php_openssl.dll

I think you can try to firstly select all the text in the field and then send the new sequence:

from selenium.webdriver.common.keys import Keys
element.sendKeys(Keys.chord(Keys.CONTROL, "a"), "55");

Use disabled true property

<TouchableOpacity disabled={true}> </TouchableOpacity>

There is one more hint that not in this conversation. for asp.net core 3.1 first add the key that you need to put it in the header, something like this:

Response.Headers.Add("your-key-to-use-it-axios", "your-value");

where you define the cors policy (normaly is in Startup.cs) you should add this key to WithExposedHeaders like this.

          services.AddCors(options =>
        {
        options.AddPolicy("CorsPolicy",
            builder => builder
                .AllowAnyHeader()
                .AllowAnyMethod()
                .AllowAnyOrigin()
                .WithExposedHeaders("your-key-to-use-it-axios"));
        });
    }

you can add all the keys here. now in your client side you can easily access to the your-key-to-use-it-axios by using the response result.

          localStorage.setItem("your-key", response.headers["your-key-to-use-it-axios"]);

you can after use it in all the client side by accessing to it like this:

const jwt = localStorage.getItem("your-key")

an easiest way which i used and worked well

date('Y-m-d', strtotime('-1 year'));

this worked perfect.. hope this will help someone else too.. :)

I also had same issue on my mac. I was running 5.3.0 version. I removed that version and installed 7.2.1 version. After this it is working in my case.

From SQL Server you can set a Unique key index on the table for (Columns that needs to be unique)

Is this what you need?

DataTable myDataTable = new DataTable();
List<int> myList = new List<int>();
foreach (DataRow row in myDataTable.Rows)
{
    myList.Add((int)row[0]);
}

For example using gsub or sub

    gsub('.*:(.*)','\\1',string)
    [1] "E001" "E002" "E003"

OpenMP is supported on many platforms (including Visual Studio 2005) and it offers a

int omp_get_num_procs();

function that returns the number of processors/cores available at the time of call.

You can't expect ObjectInputStream to automagically convert text into objects. The hexadecimal 54657374 is "Test" as text. You must be sending it directly as bytes.

I'd add that in case of really odd behavior - where you spend a couple of hours saying WTF - try manually deleting the /webapps/yourwebapp/WEB-INF/classes directory. A java source file that was moved to another package will not have its compiled class file deleted - at least in the case of an exploded web-application on TC. This can seriously drive you crazy with unpredictable behavior, especially with an annotated servlet.

How about this?

CREATE FUNCTION dbo.StripWWWandCom (@input VARCHAR(250))
RETURNS VARCHAR(250)
AS BEGIN
    DECLARE @Work VARCHAR(250)

    SET @Work = @Input

    SET @Work = REPLACE(@Work, 'www.', '')
    SET @Work = REPLACE(@Work, '.com', '')

    RETURN @work
END

and then use:

SELECT ID, dbo.StripWWWandCom (WebsiteName)
FROM dbo.YourTable .....

Of course, this is severely limited in that it will only strip www. at the beginning and .com at the end - nothing else (so it won't work on other host machine names like smtp.yahoo.com and other internet domains such as .org, .edu, .de and etc.)

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

You can use pickle module for that. This module have two methods,

1. Pickling(dump): Convert Python objects into string representation.
2. Unpickling(load): Retrieving original objects from stored string representstion.

https://docs.python.org/3.3/library/pickle.html

Code:

>>> import pickle
>>> l = [1,2,3,4]
>>> with open("test.txt", "wb") as fp:   #Pickling
...   pickle.dump(l, fp)
... 
>>> with open("test.txt", "rb") as fp:   # Unpickling
...   b = pickle.load(fp)
... 
>>> b
[1, 2, 3, 4]

Also Json

1. dump/dumps: Serialize
2. load/loads: Deserialize

https://docs.python.org/3/library/json.html

Code:

>>> import json
>>> with open("test.txt", "w") as fp:
...     json.dump(l, fp)
...
>>> with open("test.txt", "r") as fp:
...     b = json.load(fp)
...
>>> b
[1, 2, 3, 4]

                }, {}
            )
        : {}
};

Without jQuery

var qs = (function(a) {
    if (a == "") return {};
    var b = {};
    for (var i = 0; i < a.length; ++i)
    {
        var p=a[i].split('=', 2);
        if (p.length == 1)
            b[p[0]] = "";
        else
            b[p[0]] = decodeURIComponent(p[1].replace(/\+/g, " "));
    }
    return b;
})(window.location.search.substr(1).split('&'));

With an URL like ?topic=123&name=query+string, the following will return:

qs["topic"];    // 123
qs["name"];     // query string
qs["nothere"];  // undefined (object)

Google method

Tearing Google's code I found the method they use: getUrlParameters

function (b) {
    var c = typeof b === "undefined";
    if (a !== h && c) return a;
    for (var d = {}, b = b || k[B][vb], e = b[p]("?"), f = b[p]("#"), b = (f === -1 ? b[Ya](e + 1) : [b[Ya](e + 1, f - e - 1), "&", b[Ya](f + 1)][K](""))[z]("&"), e = i.dd ? ia : unescape, f = 0, g = b[w]; f < g; ++f) {
        var l = b[f][p]("=");
        if (l !== -1) {
            var q = b[f][I](0, l),
                l = b[f][I](l + 1),
                l = l[Ca](/\+/g, " ");
            try {
                d[q] = e(l)
            } catch (A) {}
        }
    }
    c && (a = d);
    return d
}

It is obfuscated, but it is understandable. It does not work because some variables are undefined.

They start to look for parameters on the url from ? and also from the hash #. Then for each parameter they split in the equal sign b[f][p]("=") (which looks like indexOf, they use the position of the char to get the key/value). Having it split they check whether the parameter has a value or not, if it has then they store the value of d, otherwise they just continue.

In the end the object d is returned, handling escaping and the + sign. This object is just like mine, it has the same behavior.

My method as a jQuery plugin

(function($) {
    $.QueryString = (function(paramsArray) {
        let params = {};

        for (let i = 0; i < paramsArray.length; ++i)
        {
            let param = paramsArray[i]
                .split('=', 2);
            
            if (param.length !== 2)
                continue;
            
            params[param[0]] = decodeURIComponent(param[1].replace(/\+/g, " "));
        }
            
        return params;
    })(window.location.search.substr(1).split('&'))
})(jQuery);

Usage

//Get a param
$.QueryString.param
//-or-
$.QueryString["param"]
//This outputs something like...
//"val"

//Get all params as object
$.QueryString
//This outputs something like...
//Object { param: "val", param2: "val" }

//Set a param (only in the $.QueryString object, doesn't affect the browser's querystring)
$.QueryString.param = "newvalue"
//This doesn't output anything, it just updates the $.QueryString object

//Convert object into string suitable for url a querystring (Requires jQuery)
$.param($.QueryString)
//This outputs something like...
//"param=newvalue&param2=val"

//Update the url/querystring in the browser's location bar with the $.QueryString object
history.replaceState({}, '', "?" + $.param($.QueryString));
//-or-
history.pushState({}, '', "?" + $.param($.QueryString));

                if (!isInCharacterRange(mb_ord($r)) || (mb_ord($r) === 0xFFFD && $Width === 1)) {
                    $esc = "\u{FFFD}";
                    break;
                }

                continue 2;
        }
        $w .= substr($s, $Last, $i - $Last - $Width) . $esc;
        $Last = $i;
    }
    $w .= substr($s, $Last);
    return $w;
}

Note you'll need at least PHP7.2 because of the mb_ord usage, or you'll have to swap it out for another polyfill, but these functions are working great for us!

For anyone curious, here is the relevant Go source https://golang.org/src/encoding/xml/xml.go?s=44219:44263#L1887

Above answers are good but If you do not want to add string include, you can use the following

ostream& operator<<(ostream& os, string& msg)
{
os<<msg.c_str();

return os;
}

This is a bit of going around the problem, but I have written a function that basically deals with the extra columns:

def merge_fix_cols(df_company,df_product,uniqueID):
    
    df_merged = pd.merge(df_company,
                         df_product,
                         how='left',left_on=uniqueID,right_on=uniqueID)    
    for col in df_merged:
        if col.endswith('_x'):
            df_merged.rename(columns = lambda col:col.rstrip('_x'),inplace=True)
        elif col.endswith('_y'):
            to_drop = [col for col in df_merged if col.endswith('_y')]
            df_merged.drop(to_drop,axis=1,inplace=True)
        else:
            pass
    return df_merged

Seems to work well with my merges!

Jin Yong - IE has an issue with polluting the global scope with object references to any DOM elements with a "name" or "id" attribute set on the "initial" page load.

Thus you may have issues due to your variable name.

Try this and see if it works.

var someOtherName="abc";
//  ^^^^^^^^^^^^^
document.getElementById('msg').value = someOtherName;
document.getElementById('sp_100').checked = true;

There is a chance (in your original code) that IE attempts to set the value of the input to a reference to that actual element (ignores the error) but leaves you with no new value.

Keep in mind that in IE6/IE7 case doesn't matter for naming objects. IE believes that "foo" "Foo" and "FOO" are all the same object.

If you don't need branch or tag name:
git log --oneline --graph --all --no-decorate

If you don't even need color (to avoid tty color sequence):
git log --oneline --graph --all --no-decorate --no-color

And a handy alias (in .gitconfig) to make life easier:

[alias]
  tree = log --oneline --graph --all --no-decorate

Only last option takes effect, so it's even possible to override your alias:
git tree --decorate

Assuming you want a grayscale image:

im = Image.new('L', (width, height))
im.putdata(an_array.flatten().tolist())
im.save("image.tiff")

I strongly suspect that's because of the network connection or the web server you're talking to - it's not BufferedReader's fault. Try measuring this:

InputStream stream = conn.getInputStream();
byte[] buffer = new byte[1000];
// Start timing
while (stream.read(buffer) > 0)
{
}
// End timing

I think you'll find it's almost exactly the same time as when you're parsing the text.

Note that you should also give InputStreamReader an appropriate encoding - the platform default encoding is almost certainly not what you should be using.

You can use eval() for this purpose

>>> url = "'http address'"
>>> eval(url)
'http address'

while eval() poses risk , i think in this context it is safe.

Another solution would be the usage of std::make_move_iterator to build a new vector (C++11 )

    int main(){

      std::map<std::string, int> map;
       //Populate map

      std::vector<std::pair<std::string, int>> v {std::make_move_iterator(begin(map)),
                                      std::make_move_iterator(end(map))};
       // Create a vector with the map parameters

       sort(begin(v), end(v),
             [](auto p1, auto p2){return p1.second > p2.second;});
       // Using sort + lambda function to return an ordered vector 
       // in respect to the int value that is now the 2nd parameter 
       // of our newly created vector v
  }

The :query_string_normalizer option is also available, which will override the default normalizer HashConversions.to_params(query)

query_string_normalizer: ->(query){query.to_json}

check all the variables names in both of the combined files. Name of variables of both files to be combines should be exact same or else it will produce the above mentioned errors. I was facing the same problem as well, and after making all names same in both the file, rbind works accurately.

Thanks

You can indeed use __call() in a generic fashion to access protected methods. To be able to test this class

class Example {
    protected function getMessage() {
        return 'hello';
    }
}

you create a subclass in ExampleTest.php:

class ExampleExposed extends Example {
    public function __call($method, array $args = array()) {
        if (!method_exists($this, $method))
            throw new BadMethodCallException("method '$method' does not exist");
        return call_user_func_array(array($this, $method), $args);
    }
}

Note that the __call() method does not reference the class in any way so you can copy the above for each class with protected methods you want to test and just change the class declaration. You may be able to place this function in a common base class, but I haven't tried it.

Now the test case itself only differs in where you construct the object to be tested, swapping in ExampleExposed for Example.

class ExampleTest extends PHPUnit_Framework_TestCase {
    function testGetMessage() {
        $fixture = new ExampleExposed();
        self::assertEquals('hello', $fixture->getMessage());
    }
}

I believe PHP 5.3 allows you to use reflection to change the accessibility of methods directly, but I assume you'd have to do so for each method individually.

Apply float:left; to both of your divs should make them stand side by side.
