Programs & Examples On #Crontrigger

According to the Quartz-Scheduler Tutorial It should be value="0 0/30 * * * ?"

The field order of the cronExpression is

1.Seconds

2.Minutes

3.Hours

4.Day-of-Month

5.Month

6.Day-of-Week

7.Year (optional field)

Ensure you have at least 6 parameters or you will get an error (year is optional)

For UNIX, try this. It worked for me:

1. connect MySQL use Navicat Premium with inital root/"password"
2. UPDATE mysql.user SET authentication_string = PASSWORD('MyNewPass'), password_expired = 'N' WHERE User = 'root' AND Host = 'localhost'; FLUSH PRIVILEGES;
3. restart MySQL

What I learn about promises is to use it only as return values avoid referencing them if possible. async/await syntax is particularly practical for that. Today all latest browsers and node support it: https://caniuse.com/#feat=async-functions , is a simple behavior and the code is like reading synchronous code, forget about callbacks...

In cases I do need to reference a promises is when creation and resolution happen at independent/not-related places. So instead an artificial association and probably an event listener just to resolve the "distant" promise, I prefer to expose the promise as a Deferred, which the following code implements it in valid es5

/**
 * Promise like object that allows to resolve it promise from outside code. Example:
 *
```
class Api {
  fooReady = new Deferred<Data>()
  private knower() {
    inOtherMoment(data=>{
      this.fooReady.resolve(data)
    })
  }
}
```
 */
var Deferred = /** @class */ (function () {
  function Deferred(callback) {
    var instance = this;
    this.resolve = null;
    this.reject = null;
    this.status = 'pending';
    this.promise = new Promise(function (resolve, reject) {
      instance.resolve = function () { this.status = 'resolved'; resolve.apply(this, arguments); };
      instance.reject = function () { this.status = 'rejected'; reject.apply(this, arguments); };
    });
    if (typeof callback === 'function') {
      callback.call(this, this.resolve, this.reject);
    }
  }
  Deferred.prototype.then = function (resolve) {
    return this.promise.then(resolve);
  };
  Deferred.prototype.catch = function (r) {
    return this.promise.catch(r);
  };
  return Deferred;
}());

transpiled form a typescript project of mine:

https://github.com/cancerberoSgx/misc-utils-of-mine/blob/2927c2477839f7b36247d054e7e50abe8a41358b/misc-utils-of-mine-generic/src/promise.ts#L31

For more complex cases I often use these guy small promise utilities without dependencies tested and typed. p-map has been useful several times. I think he covered most use cases:

https://github.com/sindresorhus?utf8=%E2%9C%93&tab=repositories&q=promise&type=source&language=

Java 8 user can do that: list.removeIf(...)

    List<String> list = new ArrayList<>(Arrays.asList("a", "b", "c"));
    list.removeIf(e -> (someCondition));

It will remove elements in the list, for which someCondition is satisfied

After googling I write a simple Exception handing based on MVC Action Filter:

public class HandleExceptionAttribute : HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
        if (filterContext.HttpContext.Request.IsAjaxRequest() && filterContext.Exception != null)
        {
            filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
            filterContext.Result = new JsonResult
            {
                JsonRequestBehavior = JsonRequestBehavior.AllowGet,
                Data = new
                {
                    filterContext.Exception.Message,
                    filterContext.Exception.StackTrace
                }
            };
            filterContext.ExceptionHandled = true;
        }
        else
        {
            base.OnException(filterContext);
        }
    }
}

and write in global.ascx:

 public static void RegisterGlobalFilters(GlobalFilterCollection filters)
 {
      filters.Add(new HandleExceptionAttribute());
 }

and then write this script on the layout or Master page:

<script type="text/javascript">
      $(document).ajaxError(function (e, jqxhr, settings, exception) {
                       e.stopPropagation();
                       if (jqxhr != null)
                           alert(jqxhr.responseText);
                     });
</script>

Finally you should turn on custom error. and then enjoy it :)

The pack method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame size explicitly by calling setSize or setBounds (which also sets the frame location). In general, using pack is preferable to calling setSize, since pack leaves the frame layout manager in charge of the frame size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.

You should also refer to Javadocs any time you need additional information on any Java API

try this;

Most common AD default design is to have a container, cn=users just after the root of the domain. Thus a DN might be:

cn=admin,cn=users,DC=domain,DC=company,DC=com

Also, you might have sufficient rights in an LDAP bind to connect anonymously, and query for (cn=admin). If so, you should get the full DN back in that query.

I've decided to give an answer to this question because I think it can be solved using a simpler syntax than the convoluted try-catch block. The Laravel documentation is pretty brief on this subject.

Instead of using try-catch, you can just use the DB::transaction(){...} wrapper like this:

// MyController.php
public function store(Request $request) {
    return DB::transaction(function() use ($request) {
        $user = User::create([
            'username' => $request->post('username')
        ]);

        // Add some sort of "log" record for the sake of transaction:
        $log = Log::create([
            'message' => 'User Foobar created'
        ]);

        // Lets add some custom validation that will prohibit the transaction:
        if($user->id > 1) {
            throw AnyException('Please rollback this transaction');
        }

        return response()->json(['message' => 'User saved!']);
    });
};

You should then see that the User and the Log record cannot exist without eachother.

Some notes on the implementation above:

• Make sure to return the transaction, so that you can use the response() you return within its callback.
• Make sure to throw an exception if you want the transaction to be rollbacked (or have a nested function that throws the exception for you automatically, like an SQL exception from within Eloquent).
• The id, updated_at, created_at and any other fields are AVAILABLE AFTER CREATION for the $user object (for the duration of this transaction). The transaction will run through any of the creation logic you have. HOWEVER, the whole record is discarded when the AnyException is thrown. This means that for instance an auto-increment column for id does get incremented on failed transactions.

Tested on Laravel 5.8

Here is a solution which blocks all non numeric input from being entered into the text-field.

html

<input type="text" id="numbersOnly" />

javascript

var input = document.getElementById('numbersOnly');
input.onkeydown = function(e) {
    var k = e.which;
    /* numeric inputs can come from the keypad or the numeric row at the top */
    if ( (k < 48 || k > 57) && (k < 96 || k > 105)) {
        e.preventDefault();
        return false;
    }
};?

If you are using pip 19.0.3 and python 3.7.4. Then go for pip list command in your virtualenv. It will show all the installed packages with respective versions.

The correct answer to that is the method lists, it's very simple like this:

$test=test::select('id')->where('id' ,'>' ,0)->lists('id');

For security reasons you must avoid providing password on a command line otherwise anyone running ps command can see your password. Better to use sshpass utility like this:

#!/bin/bash

export SSHPASS="your-password"
sshpass -e ssh -oBatchMode=no sshUser@remoteHost

How to create an array size 5 containing pointers to characters:

char *array_of_pointers[ 5 ];        //array size 5 containing pointers to char
char m = 'm';                        //character value holding the value 'm'
array_of_pointers[0] = &m;           //assign m ptr into the array position 0.

here's another solution for Python3:

import csv
with open(filename, "r") as csvfile:
    datareader = csv.reader(csvfile)
    count = 0
    for row in datareader:
        if row[3] in ("column header", criterion):
            doSomething(row)
            count += 1
        elif count > 2:
            break

here datareader is a generator function.

If you don't need to change something onMeasure - there's absolutely no need for you to override it.

Devunwired code (the selected and most voted answer here) is almost identical to what the SDK implementation already does for you (and I checked - it had done that since 2009).

You can check the onMeasure method here :

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    setMeasuredDimension(getDefaultSize(getSuggestedMinimumWidth(), widthMeasureSpec),
            getDefaultSize(getSuggestedMinimumHeight(), heightMeasureSpec));
}

public static int getDefaultSize(int size, int measureSpec) {
    int result = size;
    int specMode = MeasureSpec.getMode(measureSpec);
    int specSize = MeasureSpec.getSize(measureSpec);

    switch (specMode) {
    case MeasureSpec.UNSPECIFIED:
        result = size;
        break;
    case MeasureSpec.AT_MOST:
    case MeasureSpec.EXACTLY:
        result = specSize;
        break;
    }
    return result;
}

Overriding SDK code to be replaced with the exact same code makes no sense.

This official doc's piece that claims "the default onMeasure() will always set a size of 100x100" - is wrong.

1. Create a new Application Pool

2. Go to the Advanced Settings of this application pool

3. Set the Enable 32-Bit Application to True

4. Point your web application to use this new Pool

Xamarin.Android port: (C#)

public bool IsMainThread => Build.VERSION.SdkInt >= BuildVersionCodes.M
    ? Looper.MainLooper.IsCurrentThread
    : Looper.MyLooper() == Looper.MainLooper;

Usage:

if (IsMainThread) {
    // you are on UI/Main thread
}

Here was my scenario.

I had a multi project solution containing projects A, B, C .. N.

Project B was a code library that contained a factory for selectlist objects.

The project would run as expected in development, but when publishing to our test environment I was getting the error you were encountering:

Could not load file or assembly 'Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

What had happened was through nuget package manager, I had accidentally installed "Microsoft ASP.NET MVC" which installed dependencies for:

• Microsoft.AspNet.Razor
• Microsoft.AspNet.WebPages

Low and behold, Microsoft.AspNet.WebPages depends on "Microsoft.Web.Infrastructure".

My solution was uninstalling the three packages mentioned above (MVC, Razor, WebPages) then right click references > add reference > Assemblies > Extensions > System.Web.MVC.

Modify the following rc parameters by adding the commands to the script:

plt.rcParams['xtick.bottom'] = False
plt.rcParams['xtick.labelbottom'] = False

A sample matplotlibrc file is depicted in this section of the matplotlib documentation, which lists many other parameters like changing figure size, color of figure, animation settings, etc.

Here is a way to detect Zombie transaction

SqlTransaction trans = connection.BeginTransaction();

//some db calls here

if (trans.Connection != null) //Detecting zombie transaction
{
  trans.Commit();
}

Decompiling the SqlTransaction class, you will see the following

public SqlConnection Connection
{
  get
  {
    if (this.IsZombied)
      return (SqlConnection) null;
    return this._connection;
  }
}

I notice if the connection is closed, the transOP will become zombie, thus cannot Commit. For my case, it is because I have the Commit() inside a finally block, while the connection was in the try block. This arrangement is causing the connection to be disposed and garbage collected. The solution was to put Commit inside the try block instead.

So, It looks something like this:

git rm --cached /config/deploy.rb
echo /config/deploy.rb >> .gitignore

Remove cache for tracked file from git and add that file to .gitignore list

As no one has mentioned - I would suggest to use great tool for such purpose - swaks

I have been using swaks to send email notifications from nagios via gmail for last 5 years without any problem.

use href with indexof

<script type="text/javascript">
 $(document).ready(function () {
   if(window.location.href.indexOf("added-to-cart=555") > -1) {
   alert("your url contains the added-to-cart=555");
  }
});
</script>

As answered by Ian L, I also use NPM to manage my scripts.

Example:

{_x000D_
  "scripts": {_x000D_
    "ios": "react-native run-ios --simulator=\"iPad Air 2\"",_x000D_
    "devices": "xcrun simctl list devices"_x000D_
  }_x000D_
}

This way, I can quickly get what I need:

1. List all devices: npm run devices
2. Run the default simulator: npm run ios

Following works in Java 8..

List<String[]> addresses = new ArrayList<>();

Since R version 3.4.0 you can use strcapture() from the utils package (included with base R installs), binding the output onto the other column(s).

out <- strcapture(
    "(.*)_and_(.*)",
    as.character(before$type),
    data.frame(type_1 = character(), type_2 = character())
)

cbind(before["attr"], out)
#   attr type_1 type_2
# 1    1    foo    bar
# 2   30    foo  bar_2
# 3    4    foo    bar
# 4    6    foo  bar_2

There is a space missing between elif and [:

elif[ "$seconds" -gt 0 ]

should be

elif [ "$seconds" -gt 0 ]

As I see this question is getting a lot of views, it is important to indicate that the syntax to follow is:

if [ conditions ]
# ^ ^          ^

meaning that spaces are needed around the brackets. Otherwise, it won't work. This is because [ itself is a command.

The reason why you are not seeing something like elif[: command not found (or similar) is that after seeing if and then, the shell is looking for either elif, else, or fi. However it finds another then (after the mis-formatted elif[). Only after having parsed the statement it would be executed (and an error message like elif[: command not found would be output).

You can also do like this:

private void button2_Click(object sender, EventArgs e)
{
    System.Windows.Forms.Application.ExitThread();
}

For whatever reason, these answers didn't quite work for me. This is what worked for me instead:

In Vim, the :version command gives you the paths of system and user vimrc and gvimrc files (among other things), and the output looks something like this:

 system vimrc file: "$VIM/vimrc"
   user vimrc file: "$HOME/.vimrc"
    user exrc file: "$HOME/.exrc"
system gvimrc file: "$VIM/gvimrc"
  user gvimrc file: "$HOME/.gvimrc"

The one you want is user vimrc file: "$HOME/.vimrc"

So to edit the file: vim $HOME/.vimrc

Source: Open vimrc file

In XCode under Targets, right-click on your project and Get Info. Under the Build tab look for iOS Deployment Target. By changing this you should be able to test different iOS version.

I had to create an array of a predefined type, and I successfully did as follows:

[System.Data.DataColumn[]]$myitems = ([System.Data.DataColumn]("col1"), 
                [System.Data.DataColumn]("col2"),  [System.Data.DataColumn]("col3"))

What it does

Maven is a "build management tool", it is for defining how your .java files get compiled to .class, packaged into .jar (or .war or .ear) files, (pre/post)processed with tools, managing your CLASSPATH, and all others sorts of tasks that are required to build your project. It is similar to Apache Ant or Gradle or Makefiles in C/C++, but it attempts to be completely self-contained in it that you shouldn't need any additional tools or scripts by incorporating other common tasks like downloading & installing necessary libraries etc.

It is also designed around the "build portability" theme, so that you don't get issues as having the same code with the same buildscript working on one computer but not on another one (this is a known issue, we have VMs of Windows 98 machines since we couldn't get some of our Delphi applications compiling anywhere else). Because of this, it is also the best way to work on a project between people who use different IDEs since IDE-generated Ant scripts are hard to import into other IDEs, but all IDEs nowadays understand and support Maven (IntelliJ, Eclipse, and NetBeans). Even if you don't end up liking Maven, it ends up being the point of reference for all other modern builds tools.

Why you should use it

There are three things about Maven that are very nice.

1. Maven will (after you declare which ones you are using) download all the libraries that you use and the libraries that they use for you automatically. This is very nice, and makes dealing with lots of libraries ridiculously easy. This lets you avoid "dependency hell". It is similar to Apache Ant's Ivy.

2. It uses "Convention over Configuration" so that by default you don't need to define the tasks you want to do. You don't need to write a "compile", "test", "package", or "clean" step like you would have to do in Ant or a Makefile. Just put the files in the places in which Maven expects them and it should work off of the bat.

3. Maven also has lots of nice plug-ins that you can install that will handle many routine tasks from generating Java classes from an XSD schema using JAXB to measuring test coverage with Cobertura. Just add them to your pom.xml and they will integrate with everything else you want to do.

The initial learning curve is steep, but (nearly) every professional Java developer uses Maven or wishes they did. You should use Maven on every project although don't be surprised if it takes you a while to get used to it and that sometimes you wish you could just do things manually, since learning something new sometimes hurts. However, once you truly get used to Maven you will find that build management takes almost no time at all.

How to Start

The best place to start is "Maven in 5 Minutes". It will get you start with a project ready for you to code in with all the necessary files and folders set-up (yes, I recommend using the quickstart archetype, at least at first).

After you get started you'll want a better understanding over how the tool is intended to be used. For that "Better Builds with Maven" is the most thorough place to understand the guts of how it works, however, "Maven: The Complete Reference" is more up-to-date. Read the first one for understanding, but then use the second one for reference.

Chart.js 2.X.X

I know this post is old. But if anyone is looking for more flexible solution, here it is

var options = {
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero: true,
                    callback: function(label, index, labels) {
                        return Intl.NumberFormat().format(label);
                        // 1,350

                        return Intl.NumberFormat('hi', { 
                            style: 'currency', currency: 'INR', minimumFractionDigits: 0, 
                        }).format(label).replace(/^(\D+)/, '$1 ');
                        // ? 1,350

                        // return Intl.NumberFormat('hi', {
                            style: 'currency', currency: 'INR', currencyDisplay: 'symbol', minimumFractionDigits: 2 
                        }).format(label).replace(/^(\D+)/, '$1 ');
                        // ? 1,350.00
                    }
                }
            }]
        }
    }

May I present my guess, since this is not a open technology.

Google says it's about combing information from before, during, after to distinguish human from robot. But I am more interested about that final click on the check box.

Say, the POST data (solved CAPTCHA) has a field called fingerprint, a string calculated from user behavior. I think there may be a field about that check box location. I guess this check box is in a coordinate system randomly generated by Google back-end and encrypted by the public key of my site. So, a robot may "guess/calculate" a location about this box, but when site owner makes the GET query with private key to verify user identity, Google will decrypt the coordinate system and say if the user click on the right place. So, only one possible right click(with some offsets, it's a square box) location in this random coordinate system owned by only Google and site owners.

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity).

Make sure you refer to the property as fileName in the Criteria query, not filename.

Specifically, Hibernate will call the getter method of the filename property when executing that Criteria query, so it will look for a method called getFilename(). But the property is called FileName and the getter getFileName().

So, change the projection like so:

criteria.setProjection(Projections.property("fileName"));

To do this in t-sql, you can use the following system stored procedures to schedule a daily job. This example schedules daily at 1:00 AM. See Microsoft help for details on syntax of the individual stored procedures and valid range of parameters.

put a semicolon between the two functions as statement terminator.

Timothy Pirez answer was very correct but if you need to replace the numbers with commas Immediately as user types in textfield, u might want to use the Keyup function.

      $('#textfield').live('keyup', function (event) {
        var value=$('#textfield').val();

      if(event.which >= 37 && event.which <= 40){
          event.preventDefault();
      }
      var newvalue=value.replace(/,/g, '');   
      var valuewithcomma=Number(newvalue).toLocaleString('en');   
      $('#textfield').val(valuewithcomma); 

      });

    <form><input type="text" id="textfield" ></form>

A key issue here is that this loop iterates over the rows (1st dimension) of B:

In [258]: B
Out[258]: 
array([[ 0,  1,  2],
       [ 3,  4,  5],
       [ 6,  7,  8],
       [ 9, 10, 11]])
In [259]: for b in B:
     ...:     print(b,'=>',end='')
     ...:     b += 1
     ...:     print(b)
     ...:     
[0 1 2] =>[1 2 3]
[3 4 5] =>[4 5 6]
[6 7 8] =>[7 8 9]
[ 9 10 11] =>[10 11 12]

Thus the += is acting on a mutable object, an array.

This is implied in the other answers, but easily missed if your focus is on the a = a+1 reassignment.

I could also make an in-place change to b with [:] indexing, or even something fancier, b[1:]=0:

In [260]: for b in B:
     ...:     print(b,'=>',end='')
     ...:     b[:] = b * 2

[1 2 3] =>[2 4 6]
[4 5 6] =>[ 8 10 12]
[7 8 9] =>[14 16 18]
[10 11 12] =>[20 22 24]

Of course with a 2d array like B we usually don't need to iterate on the rows. Many operations that work on a single of B also work on the whole thing. B += 1, B[1:] = 0, etc.

What about:

PrintWriter out = response.getWriter();
out.println("THE_STRING_TO_SEND_AS_RESPONSE");
return null;

This woks for me.

To accept both @PathVariable and @RequestParam in the same /user endpoint:

@GetMapping(path = {"/user", "/user/{data}"})
public void user(@PathVariable(required=false,name="data") String data,
                 @RequestParam(required=false) Map<String,String> qparams) {
    qparams.forEach((a,b) -> {
        System.out.println(String.format("%s -> %s",a,b));
    }
  
    if (data != null) {
        System.out.println(data);
    }
}

Testing with curl:

• curl 'http://localhost:8080/user/books'
• curl 'http://localhost:8080/user?book=ofdreams&name=nietzsche'

You not only have to put the meta tag, telling that it is UTF-8 but really make the document UTF-8. You can do that with good editors (like notepad++) by converting them to "unicode" or "UTF-8 without BOM". Than you can simply use arabic characters

As this page is UTF-8, here are some examples (I hope I don't write anything rude here): ???

If you use a server side scripting language make sure that it does not output the page in a different encoding. In PHP e.g. you can set it like this:

header('Content-Type: text/html; charset=utf-8');

Actually quite easy to roll your own tester, by abusing Java's method overload ability. Though I'm still curious if there is an official method in the sdk.

Example:

class Typetester {
    void printType(byte x) {
        System.out.println(x + " is an byte");
    }
    void printType(int x) {
        System.out.println(x + " is an int");
    }
    void printType(float x) {
        System.out.println(x + " is an float");
    }
    void printType(double x) {
        System.out.println(x + " is an double");
    }
    void printType(char x) {
        System.out.println(x + " is an char");
    }
}

then:

Typetester t = new Typetester();
t.printType( yourVariable );

try running:

su -c "Your command right here" -s /bin/sh username

This will run the command as username given that you have permissions to sudo as that user.

Use the following in a stored procedure:

IF NOT EXISTS( SELECT NULL
            FROM INFORMATION_SCHEMA.COLUMNS
           WHERE table_name = 'tablename'
             AND table_schema = 'db_name'
             AND column_name = 'columnname')  THEN

  ALTER TABLE `TableName` ADD `ColumnName` int(1) NOT NULL default '0';

END IF;

Certainly, though it will only work if it's a fast forward of BRANCH2 or if you force it. The correct syntax to do such a thing is

git push <remote> <source branch>:<dest branch> 

See the description of a "refspec" on the git push man page for more detail on how it works. Also note that both a force push and a reset are operations that "rewrite history", and shouldn't be attempted by the faint of heart unless you're absolutely sure you know what you're doing with respect to any remote repositories and other people who have forks/clones of the same project.

What you have is correct. Of course, you'll see that emp1 and item1 have the same pointer value.

You can't use placeholders for column names, table names, data type names, or basically anything that isn't data.

I would use both meta, and JavaScript code and would have a link just in case.

<!DOCTYPE HTML>
<html lang="en-US">
    <head>
        <meta charset="UTF-8">
        <meta http-equiv="refresh" content="0; url=http://example.com">
        <script type="text/javascript">
            window.location.href = "http://example.com"
        </script>
        <title>Page Redirection</title>
    </head>
    <body>
        <!-- Note: don't tell people to `click` the link, just tell them that it is a link. -->
        If you are not redirected automatically, follow this <a href='http://example.com'>link to example</a>.
    </body>
</html>

For completeness, I think the best way, if possible, is to use server redirects, so send a 301 status code. This is easy to do via .htaccess files using Apache, or via numerous plugins using WordPress. I am sure there are also plugins for all the major content management systems. Also, cPanel has very easy configuration for 301 redirects if you have that installed on your server.

For Workbench 6.0

Open MySql workbench. To take database backup you need to create New Server Instance(If not available) within Server Administration.

Steps to Create New Server Instance:

1. Select New Server Instance option within Server Administrator.
2. Provide connection details.

After creating new server instance , it will be available in Server Administration list. Double click on Server instance you have created OR Click on Manage Import/Export option and Select Server Instance.

Now, From DATA EXPORT/RESTORE select DATA EXPORT option,Select Schema and Schema Object for backup.

You can take generate backup file in different way as given below-

Q.1) Backup file(.sql) contains both Create Table statements and Insert into Table Statements

ANS:

1. Select Start Export Option

Q.2) Backup file(.sql) contains only Create Table Statements, not Insert into Table statements for all tables

ANS:

1. Select Skip Table Data(no-data) option

2. Select Start Export Option

Q.3) Backup file(.sql) contains only Insert into Table Statements, not Create Table statements for all tables

ANS:

1. Select Advance Option Tab, Within Tables Panel- select no-create info-Do not write CREATE TABLE statement that re-create each dumped table option.
2. Select Start Export Option

For Workbench 6.3

1. Click on Management tab at left side in Navigator Panel
2. Click on Data Export Option
3. Select Schema
4. Select Tables
5. Select required option from dropdown below the tables list as per your requirement
6. Select Include Create schema checkbox
7. Click on Advance option
8. Select Complete insert checkbox in Inserts Panel
9. Start Export

For Workbench 8.0

1. Go to Server tab
2. Go to Database Export

This opens up something like this

3. Select the schema to export in the Tables to export
4. Click on Export to Self-Contained file
5. Check if Advanced Options... are exactly as you want the export
6. Click the button Start Export

Given this example url:

http://www.example.com/some-dir/yourpage.php?q=bogus&n=10

$_SERVER['REQUEST_URI'] will give you:

/some-dir/yourpage.php?q=bogus&n=10

Whereas $_GET['q'] will give you:

bogus

In other words, $_SERVER['REQUEST_URI'] will hold the full request path including the querystring. And $_GET['q'] will give you the value of parameter q in the querystring.

For those using Magit, hit l and =m to toggle --no-merges and =pto toggle --first-parent.

Then either just hit l again to show commits from the current branch (with none of commits merged onto it) down to end of history, or, if you want the log to end where it was branched off from master, hit o and type master.. as your range:

Use functools.partial, not lambdas! And ofc Perform is a useless function, you can pass around functions directly.

for func in [Action1, partial(Action2, p), partial(Action3, p, r)]:
  func()

one things to remember push work only with array[] not object{}.

if you want to add Like object o inside inside n

_x000D_
_x000D_
a={ b:"c",
D:"e",
F: {g:"h",
I:"j",
k:{ l:"m"
}}
}

a.F.k.n = { o: "p" };
a.F.k.n = { o: "p" };
console.log(a);
_x000D_
_x000D_
_x000D_

This picture will remove everyone's confusion hopefully which is collected from there.

Double check your text with the Hex Editor Plug-in. In your case there may have been some control characters which have crept into your text. Usually you'll look at the white-space, and it will say 32 32 32 32, or for Unicode 32 00 32 00 32 00 32 00. You may find the problem this way, providing there isn't masses of code.

Download the Hex Plugin from here; http://sourceforge.net/projects/npp-plugins/files/Hex%20Editor/

You can do this in Python using simple function:

def get_cosine(text1, text2):
  vec1 = text1
  vec2 = text2
  intersection = set(vec1.keys()) & set(vec2.keys())
  numerator = sum([vec1[x] * vec2[x] for x in intersection])
  sum1 = sum([vec1[x]**2 for x in vec1.keys()])
  sum2 = sum([vec2[x]**2 for x in vec2.keys()])
  denominator = math.sqrt(sum1) * math.sqrt(sum2)
  if not denominator:
     return 0.0
  else:
     return round(float(numerator) / denominator, 3)
dataSet1 = [3, 45, 7, 2]
dataSet2 = [2, 54, 13, 15]
get_cosine(dataSet1, dataSet2)

Whomever gets nothing back, I think he just has to enclose the result in html tags,

Like this:

<html>
<head></head>
<body>
<?php
echo $_GET['link'];
?>
<body>
</html>

Here is my contribution to the debate ... This returns a single array with the data separated and the headers listed. This works on the basis that CURL will return a headers chunk [ blank line ] data

curl_setopt($ch, CURLOPT_HEADER, 1); // we need this to get headers back
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, true);

// $output contains the output string
$output = curl_exec($ch);

$lines = explode("\n",$output);

$out = array();
$headers = true;

foreach ($lines as $l){
    $l = trim($l);

    if ($headers && !empty($l)){
        if (strpos($l,'HTTP') !== false){
            $p = explode(' ',$l);
            $out['Headers']['Status'] = trim($p[1]);
        } else {
            $p = explode(':',$l);
            $out['Headers'][$p[0]] = trim($p[1]);
        }
    } elseif (!empty($l)) {
        $out['Data'] = $l;
    }

    if (empty($l)){
        $headers = false;
    }
}

If you're just looking at values of cells you can store the values in an array of variant type. It seems that getting the value of an element in an array can be much faster than interacting with Excel, so you can see some difference in performance using an array of all cell values compared to repeatedly getting single cells.

Dim ValArray as Variant
ValArray = Range("A1:IV" & Rows.Count).Value

Then you can get a cell value just by checking ValArray( row , column )

Try this:

#foo
{
    position: absolute;
    top: 100%;
    right: 0%;
}

Here is a more generic solution based on @rindeal solution which does not work on MacOS/BSD (/r expects a file):

cat << DOC > input.txt
abc
cdef
line
DOC

$ cat << EOF | sed '/^cdef$/ r /dev/stdin' input.txt
line 1
line 2
EOF

# outputs:
abc
cdef
line 1
line 2
line

This can be used to pipe anything into the file at the given position:

$ date | sed '/^cdef$/ r /dev/stdin' input.txt

# outputs
abc
cdef
Tue Mar 17 10:50:15 CET 2020
line

Also, you could add multiple commands which allows deleting the marker line cdef:

$ date | sed '/^cdef$/ {
  r /dev/stdin
  d
}' input.txt

# outputs
abc
Tue Mar 17 10:53:53 CET 2020
line

To avoid including a large framework, I think a simple homemade class can do the trick.

Example of class to handle named parameters:

public class NamedParamStatement {
    public NamedParamStatement(Connection conn, String sql) throws SQLException {
        int pos;
        while((pos = sql.indexOf(":")) != -1) {
            int end = sql.substring(pos).indexOf(" ");
            if (end == -1)
                end = sql.length();
            else
                end += pos;
            fields.add(sql.substring(pos+1,end));
            sql = sql.substring(0, pos) + "?" + sql.substring(end);
        }       
        prepStmt = conn.prepareStatement(sql);
    }

    public PreparedStatement getPreparedStatement() {
        return prepStmt;
    }
    public ResultSet executeQuery() throws SQLException {
        return prepStmt.executeQuery();
    }
    public void close() throws SQLException {
        prepStmt.close();
    }

    public void setInt(String name, int value) throws SQLException {        
        prepStmt.setInt(getIndex(name), value);
    }

    private int getIndex(String name) {
        return fields.indexOf(name)+1;
    }
    private PreparedStatement prepStmt;
    private List<String> fields = new ArrayList<String>();
}

Example of calling the class:

String sql;
sql = "SELECT id, Name, Age, TS FROM TestTable WHERE Age < :age OR id = :id";
NamedParamStatement stmt = new NamedParamStatement(conn, sql);
stmt.setInt("age", 35);
stmt.setInt("id", 2);
ResultSet rs = stmt.executeQuery();

Please note that the above simple example does not handle using named parameter twice. Nor does it handle using the : sign inside quotes.

Usually, we define classes for this.

class XClass( object ):
   def __init__( self ):
       self.myAttr= None

x= XClass()
x.myAttr= 'magic'
x.myAttr

However, you can, to an extent, do this with the setattr and getattr built-in functions. However, they don't work on instances of object directly.

>>> a= object()
>>> setattr( a, 'hi', 'mom' )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'object' object has no attribute 'hi'

They do, however, work on all kinds of simple classes.

class YClass( object ):
    pass

y= YClass()
setattr( y, 'myAttr', 'magic' )
y.myAttr

Also had this issue and finally found the solution here. In short, you need to add the following line to your nginx fastcgi config file (/etc/nginx/fastcgi_params in Ubuntu 12.04)

fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;

To get rid of the trailing zeros, you should use the "%g" format:

float num = 1.33;
printf("%g", num); //output: 1.33

After the question was clarified a bit, that suppressing zeros is not the only thing that was asked, but limiting the output to three decimal places was required as well. I think that can't be done with sprintf format strings alone. As Pax Diablo pointed out, string manipulation would be required.

Use following property same as table and its fully dynamic:

ul {_x000D_
    width: 100%;_x000D_
    display: table;_x000D_
    table-layout: fixed; /* optional, for equal spacing */_x000D_
    border-collapse: collapse;_x000D_
}_x000D_
li {_x000D_
    display: table-cell;_x000D_
    text-align: center;_x000D_
    border: 1px solid pink;_x000D_
    vertical-align: middle;_x000D_
}

<ul>_x000D_
  <li>foo<br>foo</li>_x000D_
  <li>barbarbarbarbar</li>_x000D_
  <li>baz klxjgkldjklg </li>_x000D_
  <li>baz</li>_x000D_
  <li>baz lds.jklklds</li>_x000D_
</ul>

May be its solve your issue.

This is my working example of our simple Vue component.

<template functional>
    <div v-html="require('!!html-loader!./../svg/logo.svg')"></div>
</template>

You are suppose to use it like header(Location:../index.php) if it in another folder

Had same issue earlier solved like this :

include('/../includes/config.php'); //note '/' appearing before '../includes/config.php'

Get reference from the following example.

1. In fragment: Create a reference variable for the class whose object you want in the fragment. Simply create a setter method for the reference variable and call the setter before replacing fragment from the activity.

 MyEmployee myEmp;
 public void setEmployee(MyEmployee myEmp)
 {
     this.myEmp = myEmp;
 }

2. In activity:

   //we need to pass object myEmp to fragment myFragment

    MyEmployee myEmp = new MyEmployee();

    MyFragment myFragment = new MyFragment();

    myFragment.setEmployee(myEmp);

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    ft.replace(R.id.main_layout, myFragment);
    ft.commit();

To set up an external DB and still use your local DB, you need to edit the config.inc.php file:

On Ubuntu: sudo gedit /etc/phpmyadmin/config.inc.php

The file is roughly set up like this:

if (!empty($dbname)) {

    //Your local db setup

     $i++;
}

What you need to do is duplicate the "your local db setup" by copying and pasting it outside of the IF statement I've shown in the code below, and change the host to you external IP. Mine for example is:

$cfg['Servers'][$i]['host'] = '10.10.1.90:23306';

You can leave the defaults (unless you know you need to change them)

Save and refresh your PHPMYADMIN login page and a new dropdown should appear. You should be good to go.

EDIT: if you want to give the server a name to select at login page, rather than having just the IP address to select, add this to the server setup:

$cfg['Servers'][$i]['verbose'] = 'Name to show when selecting your server'; 

It's good if you have multiple server configs.

Here is a functional approach using map, itertools.repeat and operator.mul:

import operator
from itertools import repeat


def scalar_multiplication(vector, scalar):
    yield from map(operator.mul, vector, repeat(scalar))

Example of usage:

>>> v = [1, 2, 3, 4]
>>> c = 3
>>> list(scalar_multiplication(v, c))
[3, 6, 9, 12]

Have you looked at angular-ui bootstrap? There's a Dialog (ui.bootstrap.dialog) directive that works quite well. You can close the dialog during the call back the angular way (per the example):

$scope.close = function(result){
  dialog.close(result);
};

Update:

The directive has since been renamed Modal.

The book HTML5 Guidelines for Web Developers: Structure and Semantics for Documents suggested this way (option 1):

<aside id="sidebar">
    <section id="widget_1"></section>
    <section id="widget_2"></section>
    <section id="widget_3"></section>
</aside>

It also points out that you can use sections in the footer. So section can be used outside of the actual page content.

Note first of all that not all languages support it.

TCO applys to a special case of recursion. The gist of it is, if the last thing you do in a function is call itself (e.g. it is calling itself from the "tail" position), this can be optimized by the compiler to act like iteration instead of standard recursion.

You see, normally during recursion, the runtime needs to keep track of all the recursive calls, so that when one returns it can resume at the previous call and so on. (Try manually writing out the result of a recursive call to get a visual idea of how this works.) Keeping track of all the calls takes up space, which gets significant when the function calls itself a lot. But with TCO, it can just say "go back to the beginning, only this time change the parameter values to these new ones." It can do that because nothing after the recursive call refers to those values.

Simply use :

echo "password" | sudo -S mount -t vfat /dev/sda1 /media/usb/;
if [ $? -eq 0 ]; then
    echo -e '[ ok ] Usb key mounted'
else
    echo -e '[warn] The USB key is not mounted'
fi

Here is the Class Component code snippet you can use to solve this problem:

This approach used the ref and also scrolls smoothly to the target ref

import React, { Component } from 'react'

export default class Untitled extends Component {
  constructor(props) {
    super(props)
    this.howItWorks = React.createRef() 
  }

  scrollTohowItWorks = () =>  window.scroll({
    top: this.howItWorks.current.offsetTop,
    left: 0,
    behavior: 'smooth'
  });

  render() {
    return (
      <div>
       <button onClick={() => this.scrollTohowItWorks()}>How it works</button>
       <hr/>
       <div className="content" ref={this.howItWorks}>

pow() doesn't work with int, hence the error "error C2668:'pow': ambiguous call to overloaded function"

http://www.cplusplus.com/reference/clibrary/cmath/pow/

Write your own power function for ints:

int power(int base, int exp)
{
    int result = 1;
    while(exp) { result *= base; exp--; }
    return result;
}

Perhaps you should look at adding a Settings File. (e.g. App.Settings) Creating this file will allow you to do the following:

string mysetting = App.Default.MySetting;
App.Default.MySetting = "my new setting";

This means you can edit and then change items, where the items are strongly typed, and best of all... you don't have to touch any xml before you deploy!

The result is a Application or User contextual setting.

Have a look in the "add new item" menu for the setting file.

Load data into a table in MySQL and specify columns:

LOAD DATA LOCAL INFILE 'file.csv' INTO TABLE t1 
FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n'  
(@col1,@col2,@col3,@col4) set name=@col4,id=@col2 ;

@col1,2,3,4 are variables to hold the csv file columns (assume 4 ) name,id are table columns.

You can use the .not() method:

$(".content_box a").not(".button")

Alternatively, you can also use the :not() selector:

$(".content_box a:not('.button')")

There is little difference between the two approaches, except .not() is more readable (especially when chained) and :not() is very marginally faster. See this Stack Overflow answer for more info on the differences.

The python shutil.copytree method its a mess. I've done one that works correctly:

def copydirectorykut(src, dst):
    os.chdir(dst)
    list=os.listdir(src)
    nom= src+'.txt'
    fitx= open(nom, 'w')

    for item in list:
        fitx.write("%s\n" % item)
    fitx.close()

    f = open(nom,'r')
    for line in f.readlines():
        if "." in line:
            shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
        else:
            if not os.path.exists(dst+'/'+line[:-1]):
                os.makedirs(dst+'/'+line[:-1])
                copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
            copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
    f.close()
    os.remove(nom)
    os.chdir('..')

There is no syntax for block quote in VBA. The work around is to use the button to quickly block or unblock multiple lines of code.

Using awk.

i starts at 0, i++ will increment the value of i, but return the original value that i held before being incremented.

awk '{print i++ "," $0}' file

For C++ strings, there's no reason to use strlen. Just use string::length:

std::cout << str.length() << std::endl;

You should strongly prefer this to strlen(str.c_str()) for the following reasons:

1. Clarity: The length() (or size()) member functions unambiguously give back the length of the string. While it's possible to figure out what strlen(str.c_str()) does, it forces the reader to pause for a bit.

2. Efficiency: length() and size() run in time O(1), while strlen(str.c_str()) will take Θ(n) time to find the end of the string.

3. Style: It's good to prefer the C++ versions of functions to the C versions unless there's a specific reason to do so otherwise. This is why, for example, it's usually considered better to use std::sort over qsort or std::lower_bound over bsearch, unless some other factors come into play that would affect performance.

The only reason I could think of where strlen would be useful is if you had a C++-style string that had embedded null characters and you wanted to determine how many characters appeared before the first of them. (That's one way in which strlen differs from string::length; the former stops at a null terminator, and the latter counts all the characters in the string). But if that's the case, just use string::find:

size_t index = str.find(0);
if (index == str::npos) index = str.length();
std::cout << index << std::endl;

Hope this helps!

This following program can handle large numbers ( number of digits greater than 20 )

package com.isEven.java;
import java.util.Scanner;

public class isEvenValuate{

public static void main(String[] args) {            

        Scanner in = new Scanner(System.in);
        String digit = in.next();

        int y = Character.getNumericValue(digit.charAt(digit.length()-1));

        boolean isEven = (y&1)==0;

        if(isEven)
            System.out.println("Even");
        else
            System.out.println("Odd");

    }
}

You can use inbuilt library pickle

This library allows you to save any object in python to a file

This library will maintain the format as well

import pickle
with open('/content/list_1.txt', 'wb') as fp:
    pickle.dump(list_1, fp)

you can also read the list back as an object using same library

with open ('/content/list_1.txt', 'rb') as fp:
    list_1 = pickle.load(fp)

I refactored TibTibs answer into something that's much clearer to read. It is a bit longer because of the 80 character width and a few comments.

Additionally, it ignores blank field names and blank values.

//
// Returns a blank string if +form+ is not actually a form element.

    return '';

  var evt    = evt || window.event || { target: null };
  evt.target = evt.target || evt.srcElement || null;
  var field, query = '';

  // Transform a form field into a query-string-friendly
  // serialized form.
  //
  // [NOTE]: Replaces blank spaces from its standard '%20' representation

  var encode = function(field, name) {
    if (field.disabled) return '';

    return '&' + (name || field.name) + '=' +
           encodeURIComponent(field.value).replace(/%20/g,'+');
  }

  // Fields without names can't be serialized.
  var hasName = function(el) {
    return (el.name && el.name.length > 0)
  }

  // Ignore the usual suspects: file inputs, reset buttons,
  // buttons that did not submit the form and unchecked
  // radio buttons and checkboxes.
  var ignorableField = function(el, evt) {
    return ((el.type == 'file' || el.type == 'reset')
        || ((el.type == 'submit' || el.type == 'button') && evt.target != el)
        || ((el.type == 'checkbox' || el.type == 'radio') && !el.checked))
  }

  var parseMultiSelect = function(field) {
    var q = '';

    for (var j=field.options.length-1; j>=0; j--) {
      if (field.options[j].selected) {
        q += encode(field.options[j], field.name);
      }
    }

    return q;
  };

  for(i = form.elements.length - 1; i >= 0; i--) {
    field = form.elements[i];

    if (!hasName(field) || field.value == '' || ignorableField(field, evt))
      continue;

    query += (field.type == 'select-multiple') ? parseMultiSelect(field)
                                               : encode(field);

My attempt to create an enum with PHP...it's extremely limited since it doesn't support objects as the enum values but still somewhat useful...

            if($val == $code) {
                return $key;
            }
        }
    }

        return $reflect->getConstants();
    }
}

Obviously, Class.isAssignableFrom() tells you whether an individual class implements the given interface. So then the problem is getting the list of classes to test.

As far as I'm aware, there's no direct way from Java to ask the class loader for "the list of classes that you could potentially load". So you'll have to do this yourself by iterating through the visible jars, calling Class.forName() to load the class, then testing it.

However, it's a little easier if you just want to know classes implementing the given interface from those that have actually been loaded:

• via the Java Instrumentation framework, you can call Instrumentation.getAllLoadedClasses()
• via reflection, you can query the ClassLoader.classes field of a given ClassLoader.

If you use the instrumentation technique, then (as explained in the link) what happens is that your "agent" class is called essentially when the JVM starts up, and passed an Instrumentation object. At that point, you probably want to "save it for later" in a static field, and then have your main application code call it later on to get the list of loaded classes.

I think that coreset.o was compiled for 64-bit, and you are linking it with a 32-bit computation.o.

You can try to recompile computation.c with the '-m64' flag of gcc(1)

You can define an operator that performs the output.

std::ostream& operator<<(std::ostream& lhs, WeekEnum e) {
    switch(e) {
    case Monday: lhs << "Monday"; break;
    .. etc
    }
    return lhs;
}

Call cURL from your console app is not a good idea.

But you can use TinyRestClient which make easier to build requests :

var client = new TinyRestClient(new HttpClient(),"https://api.repustate.com/");

client.PostRequest("v2/demokey/score.json").
AddQueryParameter("text", "").
ExecuteAsync<MyResponse>();

.then(() => new Promise((resolve) => setTimeout(resolve, 15000)))

UPDATE:

when I need sleep in async function I throw in

await new Promise(resolve => setTimeout(resolve, 1000))

According to The W3C:

This attribute sets the size of the font. Possible values:

• An integer between 1 and 7. This sets the font to some fixed size, whose rendering depends on the user agent. Not all user agents may render all seven sizes.
• A relative increase in font size. The value "+1" means one size larger. The value "-3" means three sizes smaller. All sizes belong to the scale of 1 to 7.

Hence, the conversion you're asking for is not possible. The browser is not required to use specific sizes with specific size attributes.

Also note that use of the font element is discouraged by W3 in favor of style sheets.

I've seen at lot of companies are using MongoDB for realtime analytics from application logs. Its schema-freeness really fits for application logs, where record schema tends to change time-to-time. Also, its Capped Collection feature is useful because it automatically purges old data to keep the data fit into the memory.

That is one area I really think MongoDB fits for, but MySQL/PostgreSQL is more recommended in general. There're a lot of documentations and developer resources on the web, as well as their functionality and robustness.

Solution that helped me is: do not map DispatcherServlet to /*, map it to /. Final config is then:

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        ...
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

# use Decorate, Sort, Undecorate to solve the problem

def most_common(iterable):
    # Make a list with tuples: (item, index)
    # The index will be used later to break ties for most common item.
    lst = [(x, i) for i, x in enumerate(iterable)]
    lst.sort()

    # lst_final will also be a list of tuples: (count, index, item)
    # Sorting on this list will find us the most common item, and the index
    # will break ties so the one listed first wins.  Count is negative so
    # largest count will have lowest value and sort first.
    lst_final = []

    # Get an iterator for our new list...
    itr = iter(lst)

    # ...and pop the first tuple off.  Setup current state vars for loop.
    count = 1
    tup = next(itr)
    x_cur, i_cur = tup

    # Loop over sorted list of tuples, counting occurrences of item.
    for tup in itr:
        # Same item again?
        if x_cur == tup[0]:
            # Yes, same item; increment count
            count += 1
        else:
            # No, new item, so write previous current item to lst_final...
            t = (-count, i_cur, x_cur)
            lst_final.append(t)
            # ...and reset current state vars for loop.
            x_cur, i_cur = tup
            count = 1

    # Write final item after loop ends
    t = (-count, i_cur, x_cur)
    lst_final.append(t)

    lst_final.sort()
    answer = lst_final[0][2]

    return answer

print most_common(['x', 'e', 'a', 'e', 'a', 'e', 'e']) # prints 'e'
print most_common(['goose', 'duck', 'duck', 'goose']) # prints 'goose'

If you are using Eclipse then you can do this by specifying the required size for the particular application in its Run Configuration's VM Arguments as EX: -Xms128m -Xmx512m

Or if you want all applications running from your eclipse to have the same specified size then you can specify this in the eclipse.ini file which is present in your Eclipse home directory.

To get the size of the JVM during Runtime you can use Runtime.totalMemory() which returns the total amount of memory in the Java virtual machine, measured in bytes.

You have some variables that are different types in Java language like that:

 message of type string
 timestamp of type time
 count of type integer
 version of type integer

If you use a HashMap like:

HashMap<String,Object> yourHash = new HashMap<String,Object>();
yourHash.put("message","message");
yourHash.put("timestamp",timestamp);
yourHash.put("count ",count);
yourHash.put("version ",version);

If you want to use the yourHash:

for(String key : yourHash.keySet()){
  String message = (String) yourHash.get(key);
  Datetime timestamp= (Datetime) yourHash.get(key);
  int timestamp= (int) yourHash.get(key);
}

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:buttonStyle">@style/Button</item>
</style>

<style name="Button" parent="Widget.AppCompat.Button">
    <item name="android:textAllCaps">false</item>
</style>

Yes, this way:

im = Image.open('image.gif')
rgb_im = im.convert('RGB')
r, g, b = rgb_im.getpixel((1, 1))

print(r, g, b)
(65, 100, 137)

The reason you were getting a single value before with pix[1, 1] is because GIF pixels refer to one of the 256 values in the GIF color palette.

See also this SO post: Python and PIL pixel values different for GIF and JPEG and this PIL Reference page contains more information on the convert() function.

By the way, your code would work just fine for .jpg images.

I ended up rolling my own StaticServlet. It supports If-Modified-Since, gzip encoding and it should be able to serve static files from war-files as well. It is not very difficult code, but it is not entirely trivial either.

The code is available: StaticServlet.java. Feel free to comment.

Update: Khurram asks about the ServletUtils class which is referenced in StaticServlet. It is simply a class with auxiliary methods that I used for my project. The only method you need is coalesce (which is identical to the SQL function COALESCE). This is the code:

public static <T> T coalesce(T...ts) {
    for(T t: ts)
        if(t != null)
            return t;
    return null;
}

You should use the filter method rather than map unless you want to mutate the items in the array, in addition to filtering.

eg.

var filteredItems = items.filter(function(item)
{
    return ...some condition...;
});

[Edit: Of course you could always do sourceArray.filter(...).map(...) to both filter and mutate]

It is possible of course, use -l: instead of -l. For example -l:libXYZ.a to link with libXYZ.a. Notice the lib written out, as opposed to -lXYZ which would auto expand to libXYZ.

You can also implement a contains method with foldLeft, it's pretty awesome. I just love foldLeft algorithms.

For example:

object ContainsWithFoldLeft extends App {

  val list = (0 to 10).toList
  println(contains(list, 10)) //true
  println(contains(list, 11)) //false

  def contains[A](list: List[A], item: A): Boolean = {
    list.foldLeft(false)((r, c) => c.equals(item) || r)
  }
}

That is because you are not fully qualifying your cells object. Try this

With Worksheets("SheetName")
    .Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

Notice the DOT before Cells?

(update: As of March 2020, many people have reported that yolk, installed via pip install yolk3k, only returns latest version. Chris's answer seems to have the most upvotes and worked for me)

The script at pastebin does work. However it's not very convenient if you're working with multiple environments/hosts because you will have to copy/create it every time.

A better all-around solution would be to use yolk3k, which is available to install with pip. E.g. to see what versions of Django are available:

$ pip install yolk3k
$ yolk -V django
Django 1.3
Django 1.2.5
Django 1.2.4
Django 1.2.3
Django 1.2.2
Django 1.2.1
Django 1.2
Django 1.1.4
Django 1.1.3
Django 1.1.2
Django 1.0.4

yolk3k is a fork of the original yolk which ceased development in 2012. Though yolk is no longer maintained (as indicated in comments below), yolk3k appears to be and supports Python 3.

Note: I am not involved in the development of yolk3k. If something doesn't seem to work as it should, leaving a comment here should not make much difference. Use the yolk3k issue tracker instead and consider submitting a fix, if possible.

The fundamental reason/problem is that the designers of the CLS specification (which defines how languages interact with .net) did not define a means by which class members could specify that they must be called directly, rather than via callvirt, without the caller performing a null-reference check; nor did it provide a meany of defining structures which would not be subject to "normal" boxing.

Had the CLS specification defined such a means, then it would be possible for .net to consistently follow the lead established by the Common Object Model (COM), under which a null string reference was considered semantically equivalent to an empty string, and for other user-defined immutable class types which are supposed to have value semantics to likewise define default values. Essentially, what would happen would be for each member of String, e.g. Length to be written as something like [InvokableOnNull()] int String Length { get { if (this==null) return 0; else return _Length;} }. This approach would have offered very nice semantics for things which should behave like values, but because of implementation issues need to be stored on the heap. The biggest difficulty with this approach is that the semantics of conversion between such types and Object could get a little murky.

An alternative approach would have been to allow the definition of special structure types which did not inherit from Object but instead had custom boxing and unboxing operations (which would convert to/from some other class type). Under such an approach, there would be a class type NullableString which behaves as string does now, and a custom-boxed struct type String, which would hold a single private field Value of type String. Attempting to convert a String to NullableString or Object would return Value if non-null, or String.Empty if null. Attempting to cast to String, a non-null reference to a NullableString instance would store the reference in Value (perhaps storing null if the length was zero); casting any other reference would throw an exception.

Even though strings have to be stored on the heap, there is conceptually no reason why they shouldn't behave like value types that have a non-null default value. Having them be stored as a "normal" structure which held a reference would have been efficient for code that used them as type "string", but would have added an extra layer of indirection and inefficiency when casting to "object". While I don't foresee .net adding either of the above features at this late date, perhaps designers of future frameworks might consider including them.

You are dropping it, then creating it, then trying to create it again by using SELECT INTO. Change to:

DROP TABLE #TMPGUARDIAN
CREATE TABLE #TMPGUARDIAN(
LAST_NAME NVARCHAR(30),
FRST_NAME NVARCHAR(30))  

INSERT INTO #TMPGUARDIAN 
SELECT LAST_NAME,FRST_NAME  
FROM TBL_PEOPLE

In MS SQL Server you can create a table without a CREATE TABLE statement by using SELECT INTO

You can also use $("ul li:first-child") to only get the direct children of the UL.

I agree though, you need an ID or something else to identify the main UL otherwise it will just select them all. If you had a div with an ID around the UL the easiest thing to do would be$("#someDiv > ul > li")

I had the same issue until i close teamviewer running on my pc. Then it worked fine!

You may try the following:

document.getElementById("your_h1_id").innerHTML = "your new text here"

I think it is confusing to think of it in terms of negative numbers. Since it is a logarithm think of the negative values the same way you think of powers of ten. 10^3 = 1000 while 10^-3 = 0.001.

With this in mind and using the formulas from S Lists's answer (and assuming our base power is 1mW in all these cases) we can build a little table:

|--------|-------------------|
| P(dBm) |        P(mW)      |
|--------|-------------------|
|    50  |  100000           |    
|    40  |   10000           |    strong transmitter
|    30  |    1000           |             ^  
|    20  |     100           |             |
|    10  |      10           |             |
|     0  |       1           |
|   -10  |       0.1         |
|   -20  |       0.01        |
|   -30  |       0.001       |
|   -40  |       0.0001      |
|   -50  |       0.00001     |             |
|   -60  |       0.000001    |             |
|   -70  |       0.0000001   |             v
|   -80  |       0.00000001  |    sensitive receiver
|   -90  |       0.000000001 |
|--------|-------------------|

When I think of it like this I find that it's easier to see that the more negative the dBm value then the farther to the right of the decimal the actual power value is.

When it comes to mobile networks, it not so much that they aren't powerful enough, rather it is that they are more sensitive. When you see receivers specs with dBm far into the negative values, then what you are seeing is more sensitive equipment.

Normally you would want your transmitter to be powerful (further in to the positives) and your receiver to be sensitive (further in to the negatives).

I was in your shoes for a while and finally ended up using node.js, because it can do hybrid solutions like having web and socket server in one. So php backend can submit requests thru http to node web server and then broadcast it with websocket. Very efficiant way to go.

This is all that you had to do man, change his MyViewModel model to IList.

containsElement () { for e in "${@:2}"; do [[ "$e" = "$1" ]] && return 0; done; return 1; }

Now handles empty arrays correctly.

The difference between cache and persist operations is purely syntactic. cache is a synonym of persist or persist(MEMORY_ONLY), i.e. cache is merely persist with the default storage level MEMORY_ONLY

But Persist() We can save the intermediate results in 5 storage levels.

1. MEMORY_ONLY
2. MEMORY_AND_DISK
3. MEMORY_ONLY_SER
4. MEMORY_AND_DISK_SER
5. DISK_ONLY

/** * Persist this RDD with the default storage level (MEMORY_ONLY). */
def persist(): this.type = persist(StorageLevel.MEMORY_ONLY)

/** * Persist this RDD with the default storage level (MEMORY_ONLY). */
def cache(): this.type = persist()

see more details here...

Caching or persistence are optimization techniques for (iterative and interactive) Spark computations. They help saving interim partial results so they can be reused in subsequent stages. These interim results as RDDs are thus kept in memory (default) or more solid storage like disk and/or replicated. RDDs can be cached using cache operation. They can also be persisted using persist operation.

#persist, cache

These functions can be used to adjust the storage level of a RDD. When freeing up memory, Spark will use the storage level identifier to decide which partitions should be kept. The parameter less variants persist() and cache() are just abbreviations for persist(StorageLevel.MEMORY_ONLY).

Warning: Once the storage level has been changed, it cannot be changed again!

Warning -Cache judiciously... see ((Why) do we need to call cache or persist on a RDD)

Just because you can cache a RDD in memory doesn’t mean you should blindly do so. Depending on how many times the dataset is accessed and the amount of work involved in doing so, recomputation can be faster than the price paid by the increased memory pressure.

It should go without saying that if you only read a dataset once there is no point in caching it, it will actually make your job slower. The size of cached datasets can be seen from the Spark Shell..

Listing Variants...

def cache(): RDD[T]
 def persist(): RDD[T]
 def persist(newLevel: StorageLevel): RDD[T]

See below example :

val c = sc.parallelize(List("Gnu", "Cat", "Rat", "Dog", "Gnu", "Rat"), 2)
     c.getStorageLevel
     res0: org.apache.spark.storage.StorageLevel = StorageLevel(false, false, false, false, 1)
     c.cache
     c.getStorageLevel
     res2: org.apache.spark.storage.StorageLevel = StorageLevel(false, true, false, true, 1)

Note : Due to the very small and purely syntactic difference between caching and persistence of RDDs the two terms are often used interchangeably.

See more visually here....

Persist in memory and disk:

Cache

Caching can improve the performance of your application to a great extent.

For greater results, you can use listdir() method of the os module along with a generator (a generator is a powerful iterator that keeps its state, remember?). The following code works fine with both versions: Python 2 and Python 3.

Here's a code:

import os

def files(path):  
    for file in os.listdir(path):
        if os.path.isfile(os.path.join(path, file)):
            yield file

for file in files("."):  
    print (file)

The listdir() method returns the list of entries for the given directory. The method os.path.isfile() returns True if the given entry is a file. And the yield operator quits the func but keeps its current state, and it returns only the name of the entry detected as a file. All the above allows us to loop over the generator function.

Try using %0A in the URL, just like you've used %20 instead of the space character.

1. Where does user.id go after passport.serializeUser has been called?

The user id (you provide as the second argument of the done function) is saved in the session and is later used to retrieve the whole object via the deserializeUser function.

serializeUser determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}

2. We are calling passport.deserializeUser right after it where does it fit in the workflow?

The first argument of deserializeUser corresponds to the key of the user object that was given to the done function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc). In deserializeUser that key is matched with the in memory array / database or any data resource.

The fetched object is attached to the request object as req.user

Visual Flow

passport.serializeUser(function(user, done) {
    done(null, user.id);
});              ¦
                 ¦ 
                 ¦
                 +--------------------? saved to session
                                   ¦    req.session.passport.user = {id: '..'}
                                   ¦
                                   ?           
passport.deserializeUser(function(id, done) {
                   +---------------+
                   ¦
                   ? 
    User.findById(id, function(err, user) {
        done(err, user);
    });            +--------------? user object attaches to the request as req.user

Yo can use:

a.update_column :state, a.state

Check: http://apidock.com/rails/ActiveRecord/Persistence/update_column

Updates a single attribute of an object, without calling save.

The best solution for this is to create a simple parent pom file project (with packaging 'pom') generically for all projects from your organization.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>your.company</groupId>
    <artifactId>company-parent</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <distributionManagement>
        <repository>
            <id>nexus-site</id>
            <url>http://central_nexus/server</url>
        </repository>
    </distributionManagement>

</project>

This can be built, released, and deployed to your local nexus so everyone has access to its artifact.

Now for all projects which you wish to use it, simply include this section:

<parent>
  <groupId>your.company</groupId>
  <artifactId>company-parent</artifactId>
  <version>1.0.0</version>
</parent>

This solution will allow you to easily add other common things to all your company's projects. For instance if you wanted to standardize your JUnit usage to a specific version, this would be the perfect place for that.

If you have projects that use multi-module structures that have their own parent, Maven also supports chaining inheritance so it is perfectly acceptable to make your project's parent pom file refer to your company's parent pom and have the project's child modules not even aware of your company's parent.

I see from your example project structure that you are attempting to put your parent project at the same level as your aggregator pom. If your project needs its own parent, the best approach I have found is to include the parent at the same level as the rest of the modules and have your aggregator pom.xml file at the root of where all your modules' directories exist.

- pom.xml (aggregator)
    - project-parent
    - project-module1
    - project-module2

What you do with this structure is include your parent module in the aggregator and build everything with a mvn install from the root directory.

We use this exact solution at my organization and it has stood the test of time and worked quite well for us.

Stealing from @Lila (couldn't make a comment because of no formatting), this shows the module's /path/, as well:

#!/usr/bin/env python
import sys
from modulefinder import ModuleFinder
finder = ModuleFinder()
# Pass the name of the python file of interest
finder.run_script(sys.argv[1])
# This is what's different from @Lila's script
finder.report()

which produces:

Name                      File
----                      ----

...
m token                     /opt/rh/rh-python35/root/usr/lib64/python3.5/token.py
m tokenize                  /opt/rh/rh-python35/root/usr/lib64/python3.5/tokenize.py
m traceback                 /opt/rh/rh-python35/root/usr/lib64/python3.5/traceback.py

.. suitable for grepping or what have you. Be warned, it's long!

Yes there is. The preferred syntax is to favor str.format over the deprecated % operator.

print "First number is {} and second number is {}".format(first, second)

Run cat -v file.sh.

You most likely have a carriage return or no-break space in your file. cat -v will show them as ^M and M-BM- or M- respectively. It will similarly show any other strange characters you might have gotten into your file.

Remove the Windows line breaks with

tr -d '\r' < file.sh > fixedfile.sh

A little longer, but can have multiple modes and can get string with most counts or mix of datatypes.

def getmode(inplist):

Provided you are running Jupyter Notebook, the %matplotlib inline command will make your plot outputs appear in the notebook, also can be stored.

I had similiar problem and this is how I solved it:

1. In index.html file I've added manifest:

   <html manifest="cache.manifest">
   

2. In <head> section included script updating the cache:

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

3. In <body> section I've inserted onload function:

   <body onload="checkForUpdate()">
   

4. In cache.manifest I've put all files I want to cache. It is important now that it works in my case (Apache) just by updating each time the "version" comment. It is also an option to name files with "?ver=001" or something at the end of name but it's not needed. Changing just # version 1.01 triggers cache update event.

   CACHE MANIFEST
   # version 1.01
   style.css
   imgs/logo.png
   #all other files
   

   It's important to include 1., 2. and 3. points only in index.html. Otherwise

   GET http://foo.bar/resource.ext net::ERR_FAILED
   

   occurs because every "child" file tries to cache the page while the page is already cached.

5. In update_cache.js file I've put this code:

   function checkForUpdate()
   {
       if (window.applicationCache != undefined && window.applicationCache != null)
       {
           window.applicationCache.addEventListener('updateready', updateApplication);
       }
   }
   function updateApplication(event)
   {
       if (window.applicationCache.status != 4) return;
       window.applicationCache.removeEventListener('updateready', updateApplication);
       window.applicationCache.swapCache();
       window.location.reload();
   }
   

Now you just change files and in manifest you have to update version comment. Now visiting index.html page will update the cache.

The parts of solution aren't mine but I've found them through internet and put together so that it works.

Tested in IE, Firefox, and Chrome.

You can do this in Javascript.

var time = new Date();
console.log(time.getHours() + ":" + time.getMinutes() + ":" + time.getSeconds());

At present it returns 15:5:18. Note that if any of the values are less than 10, they will display using only one digit, not two.

Check this in JSFiddle

Updates:
For prefixed 0's try

var time = new Date();
console.log(
    ("0" + time.getHours()).slice(-2)   + ":" + 
    ("0" + time.getMinutes()).slice(-2) + ":" + 
    ("0" + time.getSeconds()).slice(-2));

Another way is:

Characters="TESTING"
index=1
while [ $index -le ${#Characters} ]
do
    echo ${Characters} | cut -c${index}-${index}
    index=$(expr $index + 1)
done

I believe you are looking for the setTimeout function.

To make your code a little neater, define a separate function for onclick in a <script> block:

function myClick() {
  setTimeout(
    function() {
      document.getElementById('div1').style.display='none';
      document.getElementById('div2').style.display='none';
    }, 5000);
}

then call your function from onclick

onclick="myClick();"

Pragma is the HTTP/1.0 implementation and cache-control is the HTTP/1.1 implementation of the same concept. They both are meant to prevent the client from caching the response. Older clients may not support HTTP/1.1 which is why that header is still in use.

You can't. If it was downloaded via the iTunes store it was built for a different processor and won't work in the simulator.

Look at the r.status_code attribute:

if r.status_code == 404:
    # A 404 was issued.

Demo:

>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404

If you want requests to raise an exception for error codes (4xx or 5xx), call r.raise_for_status():

>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "requests/models.py", line 664, in raise_for_status
    raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.

You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:

if r:
    # successful response

If you want to be more explicit, use if r.ok:.

The simple answer is:

token = token.replace("&", "&");

Despite the name as compared to replaceAll, replace does do a replaceAll, it just doesn't use a regular expression, which seems to be in order here (both from a performance and a good practice perspective - don't use regular expressions by accident as they have special character requirements which you won't be paying attention to).

Sean Bright's answer is probably as good as is worth thinking about from a performance perspective absent some further target requirement on performance and performance testing, if you already know this code is a hot spot for performance, if that is where your question is coming from. It certainly doesn't deserve the downvotes. Just use StringBuilder instead of StringBuffer unless you need the synchronization.

That being said, there is a somewhat deeper potential problem here. Escaping characters is a known problem which lots of libraries out there address. You may want to consider wrapping the data in a CDATA section in the XML, or you may prefer to use an XML library (including the one that comes with the JDK now) to actually generate the XML properly (so that it will handle the encoding).

Apache also has an escaping library as part of Commons Lang.

There are several options for removing one or more columns with dplyr::select() and some helper functions. The helper functions can be useful because some do not require naming all the specific columns to be dropped. Note that to drop columns using select() you need to use a leading - to negate the column names.

Using the dplyr::starwars sample data for some variety in column names:

library(dplyr)

starwars %>% 
  select(-height) %>%                  # a specific column name
  select(-one_of('mass', 'films')) %>% # any columns named in one_of()
  select(-(name:hair_color)) %>%       # the range of columns from 'name' to 'hair_color'
  select(-contains('color')) %>%       # any column name that contains 'color'
  select(-starts_with('bi')) %>%       # any column name that starts with 'bi'
  select(-ends_with('er')) %>%         # any column name that ends with 'er'
  select(-matches('^v.+s$')) %>%       # any column name matching the regex pattern
  select_if(~!is.list(.)) %>%          # not by column name but by data type
  head(2)

# A tibble: 2 x 2
homeworld species
  <chr>     <chr>  
1 Tatooine  Human  
2 Tatooine  Droid 

You can also drop by column number:

starwars %>% 
  select(-2, -(4:10)) # column 2 and columns 4 through 10

If you use Python 3.6 (possibly 3.5 or later), it doesn't give that error to me anymore. I had a similar issue, because I was using v3.4, but it went away after I uninstalled and reinstalled.

Edit December 2018: Apple seem to have finally added a button for removing the app in certain situations, including apps that never went on sale (thanks to @iwill for pointing that out), basically making the below answer irrelevant.

Edit: turns out the deleted apps still appear in Xcode -> Organizer -> Archives and there is no way to delete them from there even if there are no archives! So more looks like a fake delete of sorts.

Currently (Edit: as of July 2016) there is no way of deleting your app if it never went on sale.

However, all information except for SKU can be edited and thus reused for a new app, including the app name, Bundle ID, icon, etc etc. Because SKU can be anything (some people say they use numbers 1, 2, 3 for example) then it shouldn't be a big deal to use something unrelated for your new app.

(Honestly though I'm hoping Apple will fix this soon. I almost hear some Apple devs finding excuses for not implementing it (you know, it will break the database and will kill innocent pandas) and some managers telling the devs to just frigging do it regardless.)

Simple example

Shamelessly adapted from: http://www.gnu.org/software/automake/manual/html_node/Creating-amhello.html and tested on Ubuntu 14.04 Automake 1.14.1.

Makefile.am

SUBDIRS = src
dist_doc_DATA = README.md

README.md

Some doc.

configure.ac

AC_INIT([automake_hello_world], [1.0], [[email protected]])
AM_INIT_AUTOMAKE([-Wall -Werror foreign])
AC_PROG_CC
AC_CONFIG_HEADERS([config.h])
AC_CONFIG_FILES([
 Makefile

])
AC_OUTPUT

bin_PROGRAMS = autotools_hello_world
autotools_hello_world_SOURCES = main.c

src/main.c

#include <config.h>
#include <stdio.h>

int main (void) {
  puts ("Hello world from " PACKAGE_STRING);
  return 0;
}

Usage

autoreconf --install
mkdir build
cd build
../configure
make
sudo make install
autoconf_hello_world
sudo make uninstall

This outputs:

Hello world from automake_hello_world 1.0

Notes

• autoreconf --install generates several template files which should be tracked by Git, including Makefile.in. It only needs to be run the first time.

• make install installs:

  • the binary to /usr/local/bin
  • README.md to /usr/local/share/doc/automake_hello_world

The issue is that the Android User-Agent is a general User-Agent and there is no difference between tablet Android and mobile Android.

This is incorrect. Mobile Android has "Mobile" string in the User-Agent header. Tablet Android does not.

But it is worth mentioning that there are quite a few tablets that report "Mobile" Safari in the userAgent and the latter is not the only/solid way to differentiate between Mobile and Tablet.

This should work fine (using .text():

$("#toptitle").text("New word");

Here's a script I used to batch import a bunch of crt files in the current directory into the java keystore. Just save this to the same folder as your certificate, and run it like so:

./import_all_certs.sh

import_all_certs.sh

KEYSTORE="$(/usr/libexec/java_home)/jre/lib/security/cacerts";

function running_as_root()
{
  if [ "$EUID" -ne 0 ]
    then echo "NO"
    exit
  fi

  echo "YES"
}

function import_certs_to_java_keystore
{
  for crt in *.crt; do 
    echo prepping $crt 
    keytool -import -file $crt -storepass changeit -noprompt --alias alias__${crt} -keystore $KEYSTORE
    echo 
  done
}

if [ "$(running_as_root)" == "YES" ]
then
  import_certs_to_java_keystore
else
  echo "This script needs to be run as root!"
fi

ABoolean (with a uppercase 'B') is a Boolean object, which if not assigned a value, will default to null. boolean (with a lowercase 'b') is a boolean primitive, which if not assigned a value, will default to false.

Boolean objectBoolean;
boolean primitiveBoolean;

System.out.println(objectBoolean); // will print 'null'
System.out.println(primitiveBoolean); // will print 'false'

Citation

so in your code because boolean with small 'b' is declared it will set to false hence

boolean turnedOn;
    if(turnedOn) **meaning true**
    {
    //do stuff when the condition is false or true?
    }
    else
    {
    //do else of if ** itwill do this part bechae it is false
    }

the if(turnedon) tests a value if true, you didnt assign a value for turned on making it false, making it do the else statement :)

For the record, here is an example using a sqlite database:

import pandas as pd
import sqlite3

with sqlite3.connect("whatever.sqlite") as con:
    sql = "SELECT * FROM table_name"
    df = pd.read_sql_query(sql, con)
    print df.shape

I added the following 2 parameters: /np /nfl

So together with the 5 parameters from AndyGeek's answer, which are /njh /njs /ndl /nc /ns you get the following and it's silent:

ROBOCOPY [source] [target] /NFL /NDL /NJH /NJS /nc /ns /np

/NFL : No File List - don't log file names.
/NDL : No Directory List - don't log directory names.
/NJH : No Job Header.
/NJS : No Job Summary.
/NP  : No Progress - don't display percentage copied.
/NS  : No Size - don't log file sizes.
/NC  : No Class - don't log file classes.

You could also use Spring's UriUtils

You need to escape the double-quotes inside the search string, like this:

string orig = "\"Text\",\"Text\",\"Text\"";
string res = orig.Replace("\",\"", ";");

Note that the replacement does not occur "in place", because .NET strings are immutable. The original string will remain the same after the call; only the returned string res will have the replacements.

For ASP.NET, this worked for me on development and deployment:

<a runat="server" href="~/Subfolder/TargetPage">TargetPage</a>

Using runat="server" and the href="~/" are the keys for going to the root.

I just wrote this cos none of the answers already here were simple enough. You can replace the hardcoded 128 for whatever you want or base them off the size of the original image. All i wanted was to rescale the image into a 128x128 image, keeping the aspect ratio and centering the result in the new image.

    private Bitmap CreateLargeIconForImage(Bitmap src)
    {
        Bitmap bmp = new Bitmap(128, 128);
        Graphics g = Graphics.FromImage(bmp);

        float scale = Math.Max((float)src.Width / 128.0f, (float)src.Height / 128.0f);
        PointF p = new PointF(128.0f - ((float)src.Width / scale), 128.0f - ((float)src.Height / scale));
        SizeF size = new SizeF((float)src.Width / scale, (float)src.Height / scale);

        g.DrawImage(src, new RectangleF(p, size));

        return bmp;
    }

If you are looking to reduce the size using coding itself, you can follow this code in php.

<?php 
function compress($source, $destination, $quality) {

    $info = getimagesize($source);

    if ($info['mime'] == 'image/jpeg') 
        $image = imagecreatefromjpeg($source);

    elseif ($info['mime'] == 'image/gif') 
        $image = imagecreatefromgif($source);

    elseif ($info['mime'] == 'image/png') 
        $image = imagecreatefrompng($source);

    imagejpeg($image, $destination, $quality);

    return $destination;
}

$source_img = 'source.jpg';
$destination_img = 'destination .jpg';

$d = compress($source_img, $destination_img, 90);
?>

$d = compress($source_img, $destination_img, 90);

This is just a php function that passes the source image ( i.e., $source_img ), destination image ( $destination_img ) and quality for the image that will take to compress ( i.e., 90 ).

$info = getimagesize($source);

The getimagesize() function is used to find the size of any given image file and return the dimensions along with the file type.

Solution With PHP $n = 100;

$n*($n+1)/2 - array_sum($array) = $missing_number

and array_search($missing_number) will give the index of missing number

To set a class completely, instead of adding one or removing one, use this:

$(this).attr("class","newclass");

Advantage of this is that you'll remove any class that might be set in there and reset it to how you like. At least this worked for me in one situation.

This should do it for you - all your files will end up called Part1-Part500.

#!/bin/bash
FILENAME=10000.csv
HDR=$(head -1 $FILENAME)   # Pick up CSV header line to apply to each file
split -l 20 $FILENAME xyz  # Split the file into chunks of 20 lines each
n=1
for f in xyz*              # Go through all newly created chunks
do
   echo $HDR > Part${n}    # Write out header to new file called "Part(n)"
   cat $f >> Part${n}      # Add in the 20 lines from the "split" command
   rm $f                   # Remove temporary file
   ((n++))                 # Increment name of output part
done

The only half-way proper way to do this is

<p>
  <span style="float: right">Text on the right</span>
  <span style="float: left">Text on the left</span>
</p> 

however, this will get you into trouble if the text overflows. If you can, use divs (block level elements) and give them a fixed width.

A table (or a number of divs with the according display: table / table-row / table-cell properties) would in fact be the safest solution for this - it will be impossible to break, even if you have lots of difficult content.

Fundamentally if you use it as part of a business then its commercial use - so its not a matter of whether the tools are directly generating income or not rather one of if they are being used in support of income generation directly or indirectly.

To take your specific example, if the purpose of the site is to sell or promote your paid services/product then its a commercial enterprise.

Javascript in a browser only really has a couple of effective scopes: function scope and global scope.

If a variable isn't in function scope, it's in global scope. And global variables are generally bad, so this is a construct to keep a library's variables to itself.

The ParameterizedThreadStart takes one parameter. You can use that to send one parameter, or a custom class containing several properties.

Another method is to put the method that you want to start as an instance member in a class along with properties for the parameters that you want to set. Create an instance of the class, set the properties and start the thread specifying the instance and the method, and the method can access the properties.

MySQL Utilities by Oracle have a command called mysqldiskusage that displays the disk usage of every database: https://dev.mysql.com/doc/mysql-utilities/1.6/en/mysqldiskusage.html

problem is, it is not converted to proper format. Use function "printPreview(binaryPDFData)" to get print preview dialog of binary pdf data. you can comment script part if you don't want print dialog open.

printPreview = (data, type = 'application/pdf') => {
    let blob = null;
    blob = this.b64toBlob(data, type);
    const blobURL = URL.createObjectURL(blob);
    const theWindow = window.open(blobURL);
    const theDoc = theWindow.document;
    const theScript = document.createElement('script');
    function injectThis() {
        window.print();
    }
    theScript.innerHTML = `window.onload = ${injectThis.toString()};`;
    theDoc.body.appendChild(theScript);
};

Better to use procedure like that:

CREATE OR REPLACE FUNCTION timestamp_diff

)
RETURN NUMBER
AS

l_hours NUMBER;
l_minutes NUMBER;
l_seconds NUMBER;
l_milliseconds NUMBER;
BEGIN
SELECT extract(DAY FROM end_time_in-start_time_in)
, extract(HOUR FROM end_time_in-start_time_in)
, extract(MINUTE FROM end_time_in-start_time_in)
, extract(SECOND FROM end_time_in-start_time_in)
INTO l_days, l_hours, l_minutes, l_seconds
FROM dual;

l_milliseconds := l_seconds*1000 + l_minutes*60*1000 + l_hours*60*60*1000 + l_days*24*60*60*1000;
RETURN l_milliseconds;

END;

You can check it by calling:

To your first question:

mysql -u root -p

or

mysqladmin -u root -p "your_command"

depending on what you want to do. The password will be asked of you once you hit enter! I'm guessing you really want to use mysql and not mysqladmin.

For restarting or stopping the MySQL-server on linux, it depends on your installation, but in the common debian derivatives this will work for starting, stopping and restarting the service:

sudo /etc/init.d/mysql start
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql restart
sudo /etc/init.d/mysql status

In some newer distros this might work as well if MySQL is set up as a deamon/service.

sudo service mysql start
sudo service mysql stop
sudo service mysql restart
sudo service mysql status

But the question is really impossible to answer without knowing your particular setup.

For Blocks lover you can use ALActionBlocks to add action of gestures in block

__weak ALViewController *wSelf = self;
imageView.userInteractionEnabled = YES;
UITapGestureRecognizer *gr = [[UITapGestureRecognizer alloc] initWithBlock:^(UITapGestureRecognizer *weakGR) {
    NSLog(@"pan %@", NSStringFromCGPoint([weakGR locationInView:wSelf.view]));
}];
[self.imageView addGestureRecognizer:gr];

Assuming you have people is List of object

  Map<String, String> phoneBook=people.stream()
                                        .collect(toMap(Person::getName, Person::getAddress));

Now you need two steps :

1)

people =removeDuplicate(people);

2)

Map<String, String> phoneBook=people.stream()
                                        .collect(toMap(Person::getName, Person::getAddress));

Here is method to remove duplicate

public static List removeDuplicate(Collection<Person>  list) {
        if(list ==null || list.isEmpty()){
            return null;
        }

        Object removedDuplicateList =
                list.stream()
                     .distinct()
                     .collect(Collectors.toList());
     return (List) removedDuplicateList;

      }

Adding full example here

 package com.example.khan.vaquar;

import java.util.Arrays;
import java.util.Collection;

import java.util.stream.Collectors;

public class RemovedDuplicate {

    public static void main(String[] args) {
        Person vaquar = new Person(1, "Vaquar", "Khan");
        Person zidan = new Person(2, "Zidan", "Khan");
        Person zerina = new Person(3, "Zerina", "Khan");

        // Add some random persons
        Collection<Person> duplicateList = Arrays.asList(vaquar, zidan, zerina, vaquar, zidan, vaquar);

        //
        System.out.println("Before removed duplicate list" + duplicateList);
        //
        Collection<Person> nonDuplicateList = removeDuplicate(duplicateList);
        //
        System.out.println("");
        System.out.println("After removed duplicate list" + nonDuplicateList);
        ;

        // 1) solution Working code
        Map<Object, Object> k = nonDuplicateList.stream().distinct()
                .collect(Collectors.toMap(s1 -> s1.getId(), s1 -> s1));
        System.out.println("");
        System.out.println("Result 1 using method_______________________________________________");
        System.out.println("k" + k);
        System.out.println("_____________________________________________________________________");

        // 2) solution using inline distinct()
        Map<Object, Object> k1 = duplicateList.stream().distinct()
                .collect(Collectors.toMap(s1 -> s1.getId(), s1 -> s1));
        System.out.println("");
        System.out.println("Result 2 using inline_______________________________________________");
        System.out.println("k1" + k1);
        System.out.println("_____________________________________________________________________");

        //breacking code
        System.out.println("");
        System.out.println("Throwing exception _______________________________________________");
        Map<Object, Object> k2 = duplicateList.stream()
                .collect(Collectors.toMap(s1 -> s1.getId(), s1 -> s1));
        System.out.println("");
        System.out.println("k2" + k2);
        System.out.println("_____________________________________________________________________");
    }

    public static List removeDuplicate(Collection<Person> list) {
        if (list == null || list.isEmpty()) {
            return null;
        }

        Object removedDuplicateList = list.stream().distinct().collect(Collectors.toList());
        return (List) removedDuplicateList;

    }

}

// Model class
class Person {
    public Person(Integer id, String fname, String lname) {
        super();
        this.id = id;
        this.fname = fname;
        this.lname = lname;
    }

    private Integer id;
    private String fname;
    private String lname;

    // Getters and Setters

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getFname() {
        return fname;
    }

    public void setFname(String fname) {
        this.fname = fname;
    }

    public String getLname() {
        return lname;
    }

    public void setLname(String lname) {
        this.lname = lname;
    }

    @Override
    public String toString() {
        return "Person [id=" + id + ", fname=" + fname + ", lname=" + lname + "]";
    }

}

Results :

Here's a batch file, called base64encode.bat, that encodes base64.

@echo off
if not "%1" == "" goto :arg1exists
echo usage: base64encode input-file [output-file]
goto :eof
:arg1exists
set base64out=%2
if "%base64out%" == "" set base64out=con 
(
  set base64tmp=base64.tmp
  certutil -encode "%1" %base64tmp% > nul
  findstr /v /c:- %base64tmp%
  erase %base64tmp%
) > %base64out%

This won't be suitable for everyone, but if your application is already setup to take commands via a socket, you can use netcat to issue a commands via cron proper.

echo 'mycommand' | nc -U /tmp/myapp.sock

Or another typical standard in the industry is to have a Constants.java named class file containing all the constants to be used all over the project.

Because strip() only strips trailing and leading characters, based on what you provided. I suggest:

>>> import re
>>> name = "Barack (of Washington)"
>>> name = re.sub('[\(\)\{\}<>]', '', name)
>>> print(name)
Barack of Washington
