I encountered difficulties with Roi-Kyi Bryant's solution when multiple add-ins tried to modify the ribbon. I also don't have admin access on my work-computer, which ruled out installing the Custom UI Editor. So, if you're in the same boat as me, here's an alternative example to customising the ribbon using only Excel. Note, my solution is derived from the Microsoft guide.

1. Create Excel file/files whose ribbons you want to customise. In my case, I've created two .xlam files, Chart Tools.xlam and Priveleged UDFs.xlam, to demonstrate how multiple add-ins can interact with the Ribbon.
2. Create a folder, with any folder name, for each file you just created.
3. Inside each of the folders you've created, add a customUI and _rels folder.
4. Inside each customUI folder, create a customUI.xml file. The customUI.xml file details how Excel files interact with the ribbon. Part 2 of the Microsoft guide covers the elements in the customUI.xml file.

My customUI.xml file for Chart Tools.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:chartToolsTab" label="Chart Tools">
        <group id="relativeChartMovementGroup" label="Relative Chart Movement" >
            <button id="moveChartWithRelativeLinksButton" label="Copy and Move" imageMso="ResultsPaneStartFindAndReplace" onAction="MoveChartWithRelativeLinksCallBack" visible="true" size="normal"/>
            <button id="moveChartToManySheetsWithRelativeLinksButton" label="Copy and Distribute" imageMso="OutlineDemoteToBodyText" onAction="MoveChartToManySheetsWithRelativeLinksCallBack" visible="true" size="normal"/>
        </group >
        <group id="chartDeletionGroup" label="Chart Deletion">
            <button id="deleteAllChartsInWorkbookSharingAnAddressButton" label="Delete Charts" imageMso="CancelRequest" onAction="DeleteAllChartsInWorkbookSharingAnAddressCallBack" visible="true" size="normal"/>
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

My customUI.xml file for Priveleged UDFs.xlam looks like this

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
  <ribbon>
    <tabs>
      <tab idQ="x:privelgedUDFsTab" label="Privelged UDFs">
        <group id="privelgedUDFsGroup" label="Toggle" >
            <button id="initialisePrivelegedUDFsButton" label="Activate" imageMso="TagMarkComplete" onAction="InitialisePrivelegedUDFsCallBack" visible="true" size="normal"/>
            <button id="deInitialisePrivelegedUDFsButton" label="De-Activate" imageMso="CancelRequest" onAction="DeInitialisePrivelegedUDFsCallBack" visible="true" size="normal"/>
        </group >
      </tab>
    </tabs>
  </ribbon>
</customUI>

5. For each file you created in Step 1, suffix a .zip to their file name. In my case, I renamed Chart Tools.xlam to Chart Tools.xlam.zip, and Privelged UDFs.xlam to Priveleged UDFs.xlam.zip.
6. Open each .zip file, and navigate to the _rels folder. Copy the .rels file to the _rels folder you created in Step 3. Edit each .rels file with a text editor. From the Microsoft guide

Between the final <Relationship> element and the closing <Relationships> element, add a line that creates a relationship between the document file and the customization file. Ensure that you specify the folder and file names correctly.

<Relationship Type="http://schemas.microsoft.com/office/2006/
  relationships/ui/extensibility" Target="/customUI/customUI.xml" 
  Id="customUIRelID" />

My .rels file for Chart Tools.xlam looks like this

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="chartToolsCustomUIRel" />
    </Relationships>

My .rels file for Priveleged UDFs looks like this.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
        <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/extended-properties" Target="docProps/app.xml"/><Relationship Id="rId2" Type="http://schemas.openxmlformats.org/package/2006/relationships/metadata/core-properties" Target="docProps/core.xml"/>
        <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
        <Relationship Type="http://schemas.microsoft.com/office/2006/relationships/ui/extensibility" Target="/customUI/customUI.xml" Id="privelegedUDFsCustomUIRel" />
    </Relationships>

7. Replace the .rels files in each .zip file with the .rels file/files you modified in the previous step.
8. Copy and paste the .customUI folder you created into the home directory of the .zip file/files.
9. Remove the .zip file extension from the Excel files you created.
10. If you've created .xlam files, back in Excel, add them to your Excel add-ins.
11. If applicable, create callbacks in each of your add-ins. In Step 4, there are onAction keywords in my buttons. The onAction keyword indicates that, when the containing element is triggered, the Excel application will trigger the sub-routine encased in quotation marks directly after the onAction keyword. This is known as a callback. In my .xlam files, I have a module called CallBacks where I've included my callback sub-routines.

My CallBacks module for Chart Tools.xlam looks like

Option Explicit

Public Sub MoveChartWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartWithRelativeLinks
End Sub

Public Sub MoveChartToManySheetsWithRelativeLinksCallBack(ByRef control As IRibbonControl)
  MoveChartToManySheetsWithRelativeLinks
End Sub

Public Sub DeleteAllChartsInWorkbookSharingAnAddressCallBack(ByRef control As IRibbonControl)
  DeleteAllChartsInWorkbookSharingAnAddress
End Sub

My CallBacks module for Priveleged UDFs.xlam looks like

Option Explicit

Public Sub InitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.InitialisePrivelegedUDFs
End Sub

Public Sub DeInitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
  ThisWorkbook.DeInitialisePrivelegedUDFs
End Sub

Different elements have a different callback sub-routine signature. For buttons, the required sub-routine parameter is ByRef control As IRibbonControl. If you don't conform to the required callback signature, you will receive an error while compiling your VBA project/projects. Part 3 of the Microsoft guide defines all the callback signatures.

Here's what my finished example looks like

Some closing tips

1. If you want add-ins to share Ribbon elements, use the idQ and xlmns: keyword. In my example, the Chart Tools.xlam and Priveleged UDFs.xlam both have access to the elements with idQ's equal to x:chartToolsTab and x:privelgedUDFsTab. For this to work, the x: is required, and, I've defined its namespace in the first line of my customUI.xml file, <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.
2. If you want add-ins to access Ribbon elements shipped with Excel, use the isMSO keyword. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.

I was having trouble coloring rows in table using bootstrap table-striped class then realized delete table-striped class and do this in css file

tr:nth-of-type(odd)
{  
background-color: red;
}
tr:nth-of-type(even)
{  
background-color: blue;
}

The bootstrap table-striped class will over ride your selectors.

Find your php.ini and look for XDebug.

Set xdebug autostart to false

xdebug.remote_autostart=0  
xdebug.remote_enable=0

Disable your profiler

xdebug.profiler_enable=0

Note that there can be a performance loss even with xdebug disabled but loaded. To disable loading of the extension itself, you need to comment it in your php.ini. Find an entry looking like this:

zend_extension = "/path/to/php_xdebug.dll"

and put a ; to comment it, e.g. ;zend_extension = ….

Check out this post XDebug, how to disable remote debugging for single .php file?

You can use Amazon Corretto. It is free to use multiplatform, production-ready distribution of the OpenJDK. It comes with long-term support that will include performance enhancements and security fixes. Check the installation instructions here.

You can also check Zulu from Azul.

One more thing I like to highlight here is both Amazon Corretto and Zulu are TCK Compliant. You can see the OpenJDK builds comparison here and here.

Give hibernate.connection.url as "jdbc:oracle:thin:@127.0.0.1:1521:xe" then you can solve above issue. Because oracle's default SID is "xe" so we should give like this. When I gave like this data has been inserted into DB without any SQL exceptions, it's my real time experience.

F5 and the refresh button will look at your browser cache before asking the server for content.

Ctrl + F5 forces a load from the server.

You can set content expiration headers and/or meta tags to ensure the browser doesn't cache anything (perhaps something you can do only for the development environment).

Cleaning AUTO_INCREMENT version:

CREATE OR REPLACE FUNCTION truncate_tables(username IN VARCHAR) RETURNS void AS $$
DECLARE
    statements CURSOR FOR
        SELECT tablename FROM pg_tables
        WHERE tableowner = username AND schemaname = 'public';
BEGIN
    FOR stmt IN statements LOOP
        EXECUTE 'TRUNCATE TABLE ' || quote_ident(stmt.tablename) || ' CASCADE;';

        IF EXISTS (
            SELECT column_name 
            FROM information_schema.columns 
            WHERE table_name=quote_ident(stmt.tablename) and column_name='id'
        ) THEN
           EXECUTE 'ALTER SEQUENCE ' || quote_ident(stmt.tablename) || '_id_seq RESTART WITH 1';
        END IF;

    END LOOP;
END;
$$ LANGUAGE plpgsql;

If you can't or don't want to use the two built-in JSON serializers (JavaScriptSerializer and DataContractJsonSerializer) you can try the JsonExSerializer library - I use it in a number of projects and works quite well.

I know this already has a marked answer, but I feel I have an improvement to it.

The marked answer is a bit misleading. He set a width to the button, which is not necessary, and set widths are not "responsive". To his defense, he mentions in a comment below it, that the width is not necessary and just an example.

One thing not mentioned here, is that the words may break in the middle of a word and look messed up.

My solution, forces the break to happen between words, a nice word wrap.

.btn-responsive {
    white-space: normal !important;
    word-wrap: break-word;
}

<a href="#" class="btn btn-primary btn-responsive">Click Here</a>

It seemingly appears to be a simple question but it boggles around 2 fundamental questions. A) How to deal with a multi-scalar data while presenting in a comparative chart, and secondly, B) whether this can be done without some thumb rule practices of R programming such as i) melting data, ii) faceting, iii) adding another layer to existing one. The solution given below satisfies both the above conditions as it deals data without having to rescale it and secondly, the techniques mentioned are not used.

Here is the result,

The number type has a step value controlling which numbers are valid (along with max and min), which defaults to 1. This value is also used by implementations for the stepper buttons (i.e. pressing up increases by step).

Simply change this value to whatever is appropriate. For money, two decimal places are probably expected:

<input type="number" step="0.01">

(I'd also set min=0 if it can only be positive)

If you'd prefer to allow any number of decimal places, you can use step="any" (though for currencies, I'd recommend sticking to 0.01). In Chrome & Firefox, the stepper buttons will increment / decrement by 1 when using any. (thanks to Michal Stefanow's answer for pointing out any, and see the relevant spec here)

Here's a playground showing how various steps affect various input types:

<form>_x000D_
  <input type=number step=1 /> Step 1 (default)<br />_x000D_
  <input type=number step=0.01 /> Step 0.01<br />_x000D_
  <input type=number step=any /> Step any<br />_x000D_
  <input type=range step=20 /> Step 20<br />_x000D_
  <input type=datetime-local step=60 /> Step 60 (default)<br />_x000D_
  <input type=datetime-local step=1 /> Step 1<br />_x000D_
  <input type=datetime-local step=any /> Step any<br />_x000D_
  <input type=datetime-local step=0.001 /> Step 0.001<br />_x000D_
  <input type=datetime-local step=3600 /> Step 3600 (1 hour)<br />_x000D_
  <input type=datetime-local step=86400 /> Step 86400 (1 day)<br />_x000D_
  <input type=datetime-local step=70 /> Step 70 (1 min, 10 sec)<br />_x000D_
</form>

As usual, I'll add a quick note: remember that client-side validation is just a convenience to the user. You must also validate on the server-side!

Not sure in python 2.x but in python 3.6, assuming you are trying to run the whole suite, you just have to use -t

-t, --top-level-directory directory Top level directory of project (defaults to start directory)

So, on a structure like

project_root
  |
  |----- my_module
  |          \
  |           \_____ my_class.py
  |
  \ tests
      \___ test_my_func.py

One could for example use:

python3 unittest discover -s /full_path/project_root/tests -t /full_path/project_root/

And still import the my_module.my_class without major dramas.

There are two points to considerate.

1) This source code worked for me:

private static string Execute(string credentials, string scriptDir, string scriptFilename)
{ 
  Process process = new Process();
  process.StartInfo.UseShellExecute = false;
  process.StartInfo.WorkingDirectory = scriptDir;
  process.StartInfo.RedirectStandardOutput = true;
  process.StartInfo.FileName = "sqlplus";
  process.StartInfo.Arguments = string.Format("{0} @{1}", credentials, scriptFilename);
  process.StartInfo.CreateNoWindow = true;

  process.Start();
  string output = process.StandardOutput.ReadToEnd();
  process.WaitForExit();

  return output;
}

I set the working directory to the script directory, so that sub scripts within the script also work.

Call it e.g. as Execute("usr/pwd@service", "c:\myscripts", "script.sql")

2) You have to finalize your SQL script with the statement EXIT;

Type sudo apt-get install moreutils into your shell and then, once that has installed, type errno 2. You can also use errno -l for all error numbers, or see only the file ones by piping it to grep, like this: errno -l | grep file.

you can also do it like that :

$ver = $em->getRepository('GedDocumentBundle:version')->search($val);

$tail = sizeof($ver);

I like TcpCatcher because it is very simple to use and has a modern interface. It is provided as a jar file, you just download it and run it (no installation process). Also, it comes with a very useful "on the fly" packets modification features (debug mode).

Note that if you are getting this error instead:

fatal: could not read Username for 'https://github.com': No error

Then you need to update your Git to version 2.16 or later.

You can use Drawable instead of Uri.

   ImageView iv=(ImageView)findViewById(R.id.imageView1);
   String pathName = "/external/images/media/470939"; 
   Drawable image = Drawable.createFromPath(pathName);
   iv.setImageDrawable(image);

This would work.

Set to today:

$('#date_pretty').datepicker('setDate', '+0');

Set to yesterday:

$('#date_pretty').datepicker('setDate', '-1');

And so on with any number of days before or after today's date.

See jQuery UI › Methods › setDate.

I like Kyle Simpson's definition of a closure:

Closure is when a function is able to remember and access its lexical scope even when that function is executing outside its lexical scope.

Lexical scope is when an inner scope can access its outer scope.

Here is a modified example he provides in his book series 'You Don't Know JS: Scopes & Closures'.

function foo() {
  var a = 2;

  function bar() {
    console.log( a );
  }
  return bar;
}

function test() {
  var bz = foo();
  bz();
}

// prints 2. Here function bar referred by var bz is outside 
// its lexical scope but it can still access it
test(); 

go to the directory of .Net framework and register their the respective dll with Regsvr32.exe white space dll path.

I think I've seen something similar when folders were moved on the server but the working copies were still bound to the older SVN folder structure. Not sure if anyone moved things around in your trunk before you had the chance to merge the branch.

Is that a possibility?

#input_box {
    margin: 0 auto;
    text-align: left;
}
#div {
    text-align: center;
}

<div id="div">
    <label for="input_box">Input: </label><input type="text" id="input_box" name="input_box" />
</div>

or you could do it using padding, but this is not that great of an idea.

I came across a similar yet slightly different issue and it took 2 days to understand the issue.

• In my case also POST array was empty.

• Then checked with file_get_contents('php://input'); and that was also empty.

Later I found that browser wasnt asking confirmation for resubmitting form data after If I refresh the page loaded after POST submission. It was directly refreshing page. But when I changed form URL to a different one it was passing POST properly and asked for resubmitting data when attempted to refresh page.

Then I checked what is wrong with actual URL . There were no fault with URL, however it was pointing to a folder without index.php in URL and I was checking POST at index.php.

Here I doubted the redirection from / to /index.php causes POST data to be lost and tested URL with appending index.php to the URL.

That Worked.

Posted it here so someone would find it helpful.

Prior to running python, type cd in the commmand line, and it will tell you the directory you are currently in. When python runs, it can only access files in this directory. hello.py needs to be in this directory, so you can move hello.py from its existing location to this folder as you would move any other file in Windows or you can change directories and run python in the directory hello.py is.

Edit: Python cannot access the files in the subdirectory unless a path to it provided. You can access files in any directory by providing the path. python C:\Python27\Projects\hello.p

This is the code to create dropdown in Angular 7, 8, 9

.html file code

<div>
<label>Summary: </label>
<select (change)="SelectItem($event.target.value)" class="select">
  <option value="0">--All--</option>
  <option *ngFor="let item of items" value="{{item.Id.Value}}">
    {{item.Name}}
  </option>
</select>
</div>

.ts file code

SelectItem(filterVal: any)
{
    var id=filterVal;
    //code
}

items is an array which should be initialized in .ts file.

Results I had varied by browser.

Chrome- 127.0.0.1 worked but localhost .localhost and "" did not. Firefox- .localhost worked but localhost, 127.0.0.1, and "" did not.

Have not tested in Opera, IE, or Safari

In my case, setting the 'Gradle version' same as the 'Android Plugin version' under File->Project Structure->Project fixed the issue for me.

I think a transaction is an atomic action in terms of DBMS.

that means it cannot be seperated. yes, in a transction, there may be several instructions for the system to execute. but they are binded together to finished a single basic task.

for example. you need to walk through a bridge (let's treat this as a transction), and to do this, say, you need 100 steps. overall, these steps cannot be seperated. when you've done half of them, there is only two choice for you: continue to finish them all, and go back to the start point. it's just like the to result of a transaction: success( committed ) and fail( rollback )

Check if data is a empty string (and ignore any white space) with jQuery:

function isBlank( data ) {
    return ( $.trim(data).length == 0 );
}

According to a user on PHP.net site, his efforts to keep session alive failed, so he had to make a workaround.

<?php

$Lifetime = 3600;
$separator = (strstr(strtoupper(substr(PHP_OS, 0, 3)), "WIN")) ? "\\" : "/";

$DirectoryPath = dirname(__FILE__) . "{$separator}SessionData";
//in Wamp for Windows the result for $DirectoryPath
//would be C:\wamp\www\your_site\SessionData

is_dir($DirectoryPath) or mkdir($DirectoryPath, 0777);

if (ini_get("session.use_trans_sid") == true) {
    ini_set("url_rewriter.tags", "");
    ini_set("session.use_trans_sid", false);

}

ini_set("session.gc_maxlifetime", $Lifetime);
ini_set("session.gc_divisor", "1");
ini_set("session.gc_probability", "1");
ini_set("session.cookie_lifetime", "0");
ini_set("session.save_path", $DirectoryPath);
session_start();

?>

In SessionData folder it will be stored text files for holding session information, each file would be have a name similar to "sess_a_big_hash_here".

In Visual Studio 2013 AND VS15 (but i guess if the same for all other version) just press F4 and change this two properties: -Anonymous Authentication: Disable -Windows Authentication: Enable

Hi its quite simple to make switch between buttons using switch case:-

 package com.example.browsebutton;


    import android.app.Activity;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.Toast;

        public class MainActivity extends Activity implements OnClickListener {
        Button b1,b2;
            @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);
                b1=(Button)findViewById(R.id.button1);

                b2=(Button)findViewById(R.id.button2);
                b1.setOnClickListener(this);
                b2.setOnClickListener(this);
            }



            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                 int id=v.getId();
                 switch(id) {
                    case R.id.button1:
                  Toast.makeText(getBaseContext(), "btn1", Toast.LENGTH_LONG).show();
                //Your Operation

                  break;

                    case R.id.button2:
                          Toast.makeText(getBaseContext(), "btn2", Toast.LENGTH_LONG).show();


                          //Your Operation
                          break;
            }

        }}

Difficult question to answer - as with most technology solutions, it really depends on your situation and since you have not described the problem you are trying to solve, how can anyone propose a solution?

You need to test them both to see which of them satisfied your needs.

With that said, MongoDB does not require any expensive hardware. Like any other database solution, it will work better with more CPU and memory but is certainly not a requirement - especially for early development purposes.

This might sound normal but I was getting the same error but just updated it and it worked now without any error. I suggests anyone to try for updates first.

Given this is the number one Google result for format number commas java, here's an answer that works for people who are working with whole numbers and don't care about decimals.

String.format("%,d", 2000000)

outputs:

2,000,000

According to the .NET user guide:

Download the .NET client library:

Add these using statements:

using Google.GData.Client;
using Google.GData.Extensions;
using Google.GData.Spreadsheets;

Authenticate:

SpreadsheetsService myService = new SpreadsheetsService("exampleCo-exampleApp-1");
myService.setUserCredentials("[email protected]", "mypassword");

Get a list of spreadsheets:

SpreadsheetQuery query = new SpreadsheetQuery();
SpreadsheetFeed feed = myService.Query(query);

Console.WriteLine("Your spreadsheets: ");
foreach (SpreadsheetEntry entry in feed.Entries)
{
    Console.WriteLine(entry.Title.Text);
}

Given a SpreadsheetEntry you've already retrieved, you can get a list of all worksheets in this spreadsheet as follows:

AtomLink link = entry.Links.FindService(GDataSpreadsheetsNameTable.WorksheetRel, null);

WorksheetQuery query = new WorksheetQuery(link.HRef.ToString());
WorksheetFeed feed = service.Query(query);

foreach (WorksheetEntry worksheet in feed.Entries)
{
    Console.WriteLine(worksheet.Title.Text);
}

And get a cell based feed:

AtomLink cellFeedLink = worksheetentry.Links.FindService(GDataSpreadsheetsNameTable.CellRel, null);

CellQuery query = new CellQuery(cellFeedLink.HRef.ToString());
CellFeed feed = service.Query(query);

Console.WriteLine("Cells in this worksheet:");
foreach (CellEntry curCell in feed.Entries)
{
    Console.WriteLine("Row {0}, column {1}: {2}", curCell.Cell.Row,
        curCell.Cell.Column, curCell.Cell.Value);
}

In the initialization chunk I define a function

pagebreak <- function() {
  if(knitr::is_latex_output())
    return("\\newpage")
  else
    return('<div style="page-break-before: always;" />')
}

In the markdown part where I want to insert a page break, I type

`r pagebreak()`

If we use tMOdel.setRowCount(0); we can get Empty table.

DefaultTableModel tMOdel = (DefaultTableModel) jtableName.getModel();
tMOdel.setRowCount(0);

In most cases, you should use the instanceof operator to test whether an object is an array.

Generally, you test an object's type before downcasting to a particular type which is known at compile time. For example, perhaps you wrote some code that can work with a Integer[] or an int[]. You'd want to guard your casts with instanceof:

if (obj instanceof Integer[]) {
    Integer[] array = (Integer[]) obj;
    /* Use the boxed array */
} else if (obj instanceof int[]) {
    int[] array = (int[]) obj;
    /* Use the primitive array */
} else ...

At the JVM level, the instanceof operator translates to a specific "instanceof" byte code, which is optimized in most JVM implementations.

In rarer cases, you might be using reflection to traverse an object graph of unknown types. In cases like this, the isArray() method can be helpful because you don't know the component type at compile time; you might, for example, be implementing some sort of serialization mechanism and be able to pass each component of the array to the same serialization method, regardless of type.

There are two special cases: null references and references to primitive arrays.

A null reference will cause instanceof to result false, while the isArray throws a NullPointerException.

Applied to a primitive array, the instanceof yields false unless the component type on the right-hand operand exactly matches the component type. In contrast, isArray() will return true for any component type.

In addition, any app lock password should be removed by SETTINGS>APP LOCK ,enter the set password and remove the lock. This worked for me on REDMI 4A

I used

View.inflate(getContext(), R.layout.whatever, null)

The using of View.inflate prevents the warning of using null at getLayoutInflater().inflate().

Floating point numbers are encoded using an exponential form, that is something like m * b ^ e, i.e. not like integers at all. The question you ask would be meaningful in the context of fixed point numbers. There are numerous fixed point arithmetic libraries available.

Regarding floating point arithmetic: The number of decimal digits depends on the presentation and the number system. For example there are periodic numbers (0.33333) which do not have a finite presentation in decimal but do have one in binary and vice versa.

Also it is worth mentioning that floating point numbers up to a certain point do have a difference larger than one, i.e. value + 1 yields value, since value + 1 can not be encoded using m * b ^ e, where m, b and e are fixed in length. The same happens for values smaller than 1, i.e. all the possible code points do not have the same distance.

Because of this there is no precision of exactly n digits like with fixed point numbers, since not every number with n decimal digits does have a IEEE encoding.

There is a nearly obligatory document which you should read then which explains floating point numbers: What every computer scientist should know about floating point arithmetic.

There is a bug filed for Eclipse:

I have same problem.

I fixed by android sdk tool version downgrade.

The steps.

1. Delete android sdk "tools" folder : [Your Android SDK root]/tools -> tools

2. Download SDK Tools: http://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip

3. Extract that to Android SDK root

4. Build your project

If you're using xml background instead of IMG, just remove this :

<item>
    <bitmap android:src="@drawable/YOURIMAGE"/>
</item>

from the 1st answer that @Ljdawson gave us.

The problem with your code seems to be the elseif-statement which should be else if (Notice the space).

I rewrote and simplyfied the code to this:

$(document).ready(function () {

    if (screen.width < 1024) {
        $(".yourClass").hide();
    }
    else {

        $(".yourClass").show();
    }

});

VB6/VBA uses deterministic approach to destoying objects. Each object stores number of references to itself. When the number reaches zero, the object is destroyed.

Object variables are guaranteed to be cleaned (set to Nothing) when they go out of scope, this decrements the reference counters in their respective objects. No manual action required.

There are only two cases when you want an explicit cleanup:

1. When you want an object to be destroyed before its variable goes out of scope (e.g., your procedure is going to take long time to execute, and the object holds a resource, so you want to destroy the object as soon as possible to release the resource).

2. When you have a circular reference between two or more objects.

   If objectA stores a references to objectB, and objectB stores a reference to objectA, the two objects will never get destroyed unless you brake the chain by explicitly setting objectA.ReferenceToB = Nothing or objectB.ReferenceToA = Nothing.

The code snippet you show is wrong. No manual cleanup is required. It is even harmful to do a manual cleanup, as it gives you a false sense of more correct code.

If you have a variable at a class level, it will be cleaned/destroyed when the class instance is destructed. You can destroy it earlier if you want (see item 1.).

If you have a variable at a module level, it will be cleaned/destroyed when your program exits (or, in case of VBA, when the VBA project is reset). You can destroy it earlier if you want (see item 1.).

Access level of a variable (public vs. private) does not affect its life time.

If you have some form data for example sent to home#action, now you want to redirect them to house#act while keeping the parameters, you can do this

redirect_to act_house_path(request.parameters)

The math.log function is to the base e, i.e. natural logarithm. If you want to the base 10 use math.log10.

I got the same question here. If the document is huge, it is not a good idea to use XmlDocument. The fact is that the first element is the root element, based on which XmlReader can be used to get the root element. Using XmlReader will be much more efficient than using XmlDocument as it doesn't require load the whole document into memory.

  using (XmlReader reader = XmlReader.Create(<your_xml_file>)) {
    while (reader.Read()) {
      // first element is the root element
      if (reader.NodeType == XmlNodeType.Element) {
        System.Console.WriteLine(reader.Name);
        break;
      }
    }
  }

Practically its not good to do. But if you want to do like this, just make listview's height fixed to wrap_content.

android:layout_height="wrap_content"

This would be the Unicode solution

String s = "A função, Ãugent";
String r = s.replaceAll("\\P{InBasic_Latin}", "");

\p{InBasic_Latin} is the Unicode block that contains all letters in the Unicode range U+0000..U+007F (see regular-expression.info)

\P{InBasic_Latin} is the negated \p{InBasic_Latin}

I feel most people have pip installed already with Python. On Windows, one way to check for pip is to open Command Prompt and typing in:

python -m pip

If you get Usage and Commands instructions then you have it installed. If python was not found though, then it needs to be added to the path. Alternatively you can run the same command from within the installation directory of python.

If all is good, then this command will install BeautifulSoup easily:

python -m pip install BeautifulSoup4

Screenshot:

N' now I see I need to upgrade my pip, which I just did :)

curl can only follow http redirects. To also follow meta refresh directives and javascript redirects, you need a full-blown browser like headless chrome:

#!/bin/bash
real_url () {
    printf 'location.href\nquit\n' | \
    chromium-browser --headless --disable-gpu --disable-software-rasterizer \
    --disable-dev-shm-usage --no-sandbox --repl "$@" 2> /dev/null \
    | tr -d '>>> ' | jq -r '.result.value'
}

If you don't have chrome installed, you can use it from a docker container:

#!/bin/bash
real_url () {
    printf 'location.href\nquit\n' | \
    docker run -i --rm --user "$(id -u "$USER")" --volume "$(pwd)":/usr/src/app \
    zenika/alpine-chrome --no-sandbox --repl "$@" 2> /dev/null \
    | tr -d '>>> ' | jq -r '.result.value'
}

Like so:

$ real_url http://dx.doi.org/10.1016/j.pgeola.2020.06.005 
https://www.sciencedirect.com/science/article/abs/pii/S0016787820300638?via%3Dihub

Question might be a little dated, but you could simply use AbstractMap.SimpleEntry<> as follows:

private Map<String, AttributeType> mapConfig(
    Map<String, String> input, String prefix) {
       int subLength = prefix.length();
       return input.entrySet()
          .stream()
          .map(e -> new AbstractMap.SimpleEntry<>(
               e.getKey().substring(subLength),
               AttributeType.GetByName(e.getValue()))
          .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));

any other Pair-like value object would work too (ie. ApacheCommons Pair tuple).

This has a simple method using SendKeys to unprotect the VBA project. This would get you into the project, so you'd have to continue on using SendKeys to figure out a way to remove the password protection: http://www.pcreview.co.uk/forums/thread-989191.php

And here's one that uses a more advanced, somewhat more reliable method for unprotecting. Again, it will only unlock the VB project for you. http://www.ozgrid.com/forum/showthread.php?t=13006&page=2

I haven't tried either method, but this may save you some time if it's what you need to do...

The short answer is adb is used via command line. find adb.exe on your machine, add it to the path and use it from cmd on windows.

"adb devices" will give you a list of devices adb can talk to. your emulation platform should be on the list. just type adb to get a list of commands and what they do.

This worked for me:

char yyy[6];

String xxx;

yyy[0]='h';

yyy[1]='e';

yyy[2]='l';

yyy[3]='l';

yyy[4]='o';

yyy[5]='\0';

xxx=String(yyy);

Not in the Standard library for 2.5, but ipaddr makes this very easy. I believe it is in 3.3 under the name ipaddress.

import ipaddr

a = ipaddr.IPAddress('192.168.0.1')
n = ipaddr.IPNetwork('192.168.0.0/24')

#This will return True
n.Contains(a)

I see you've found your answer, however it didn't work for me. Delete kept returning false, so I tried the following and it worked (For anybody else for whom the chosen answer didn't work):

System.out.println(new File(path).getAbsoluteFile().delete());

The System out can be ignored obviously, I put it for convenience of confirming the deletion.

Yet another solution:

I got inside objects.mk file

################################################################################
# Automatically-generated file. Do not edit!
################################################################################

USER_OBJS := /home/../mylib.so

LIBS := -lstdc++fs -lGL -lGLU -lGLEW -lglut -lm -lmylib

then didn't read first line. Then altered next line. It was another projects' folder because I copied this using "copy/clone project" feature and this was causing the error for me. I changed myLib.so into /proper_address/reallyMyLib.so and it worked.

Warning: It may harm some unknown places! Backup whole project before doing this. Because it says "do not edit".

Another approach would be using a java 8 stream.

    List<Customer> customer = myObjects.stream()
                                  .filter(Customer.class::isInstance)
                                  .map(Customer.class::cast)
                                  .collect(toList());

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

What you describe is the correct way to handle this.

You said that you want to stay in the GUI. You can usually set the execute bit through the file properties menu. You could also learn how to create a custom action for the context menu to do this for you if you're so inclined. This depends on your desktop environment of course.

If you use a more advanced editor, you can script the action to happen when the file is saved. For example (I'm only really familiar with vim), you could add this to your .vimrc to make any new file that starts with "#!/*/bin/*" executable.

au BufWritePost * if getline(1) =~ "^#!" | if getline(1) =~ "/bin/" | silent !chmod +x <afile> | endif | endif

Both rebase (and cherry-pick) and merge have their advantages and disadvantages. I argue for merge here, but it's worth understanding both. (Look here for an alternate, well-argued answer enumerating cases where rebase is preferred.)

merge is preferred over cherry-pick and rebase for a couple of reasons.

1. Robustness. The SHA1 identifier of a commit identifies it not just in and of itself but also in relation to all other commits that precede it. This offers you a guarantee that the state of the repository at a given SHA1 is identical across all clones. There is (in theory) no chance that someone has done what looks like the same change but is actually corrupting or hijacking your repository. You can cherry-pick in individual changes and they are likely the same, but you have no guarantee. (As a minor secondary issue the new cherry-picked commits will take up extra space if someone else cherry-picks in the same commit again, as they will both be present in the history even if your working copies end up being identical.)
2. Ease of use. People tend to understand the merge workflow fairly easily. rebase tends to be considered more advanced. It's best to understand both, but people who do not want to be experts in version control (which in my experience has included many colleagues who are damn good at what they do, but don't want to spend the extra time) have an easier time just merging.

Even with a merge-heavy workflow rebase and cherry-pick are still useful for particular cases:

1. One downside to merge is cluttered history. rebase prevents a long series of commits from being scattered about in your history, as they would be if you periodically merged in others' changes. That is in fact its main purpose as I use it. What you want to be very careful of, is never to rebase code that you have shared with other repositories. Once a commit is pushed someone else might have committed on top of it, and rebasing will at best cause the kind of duplication discussed above. At worst you can end up with a very confused repository and subtle errors it will take you a long time to ferret out.
2. cherry-pick is useful for sampling out a small subset of changes from a topic branch you've basically decided to discard, but realized there are a couple of useful pieces on.

As for preferring merging many changes over one: it's just a lot simpler. It can get very tedious to do merges of individual changesets once you start having a lot of them. The merge resolution in git (and in Mercurial, and in Bazaar) is very very good. You won't run into major problems merging even long branches most of the time. I generally merge everything all at once and only if I get a large number of conflicts do I back up and re-run the merge piecemeal. Even then I do it in large chunks. As a very real example I had a colleague who had 3 months worth of changes to merge, and got some 9000 conflicts in 250000 line code-base. What we did to fix is do the merge one month's worth at a time: conflicts do not build up linearly, and doing it in pieces results in far fewer than 9000 conflicts. It was still a lot of work, but not as much as trying to do it one commit at a time.

You can store them in tasks, then await them all:

var catTask = FeedCat();
var houseTask = SellHouse();
var carTask = BuyCar();

await Task.WhenAll(catTask, houseTask, carTask);

Cat cat = await catTask;
House house = await houseTask;
Car car = await carTask;

Use this simple formula. It works.

Suppose time stamp in A2:

=DATE(YEAR(A2),MONTH(A2),DAY(A2))

Here is a proper explanation of "still reachable":

"Still reachable" are leaks assigned to global and static-local variables. Because valgrind tracks global and static variables it can exclude memory allocations that are assigned "once-and-forget". A global variable assigned an allocation once and never reassigned that allocation is typically not a "leak" in the sense that it does not grow indefinitely. It is still a leak in the strict sense, but can usually be ignored unless you are pedantic.

Local variables that are assigned allocations and not free'd are almost always leaks.

Here is an example

int foo(void)
{
    static char *working_buf = NULL;
    char *temp_buf;
    if (!working_buf) {
         working_buf = (char *) malloc(16 * 1024);
    }
    temp_buf = (char *) malloc(5 * 1024);

    ....
    ....
    ....

}

Valgrind will report working_buf as "still reachable - 16k" and temp_buf as "definitely lost - 5k".

FOR KOTLIN USERS

inside your getView(...) method if you try to start an activity through button onClickListener:

   myButton.setOnClickListener{
        val intent = Intent(this@CurrentActivity, SecondActivity::class.java)
        startActivity(intent)
   }

Pass the correct pointer for "this"

Just sharing as this was my solution thanks to Canavar's post.

If you have something like this:

"http://localhost:1234/Default.aspx?un=asdf&somethingelse=fdsa"

or like this:

"https://www.something.com/index.html?a=123&b=4567"

and you only want the part that a user would type in then this will work:

String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery;
String strUrl = HttpContext.Current.Request.Url.AbsoluteUri.Replace(strPathAndQuery, "/");

which would result in these:

"http://localhost:1234/"
"https://www.something.com/"

You can use C style string formatting:

"%d:%d:d" % (hours, minutes, seconds)

See here, especially: https://web.archive.org/web/20120415173443/http://diveintopython3.ep.io/strings.html

You may use Window#dispose() method to release all of the native screen resources, subcomponents, and all of its owned children.

The System.exit(0) will terminates the currently running Java Virtual Machine.

One other significant point if you're using C# 6:

'=>' can be used instead of 'get' and is only for 'get only' methods - it can't be used with a 'set'.

For C# 7, see the comment from @avenmore below - it can now be used in more places. Here's a good reference - https://csharp.christiannagel.com/2017/01/25/expressionbodiedmembers/

1. Use the 'jet' colormap for a transition between blue and red.
2. Use pcolor() with the vmin, vmax parameters.

It is detailed in this answer: https://stackoverflow.com/a/3376734/21974

I use the following code on http://www.diagnomics.com/

Smooth transition from b/w to color with magnifying effect (scale)

    img.color_flip {
      filter: url(filters.svg#grayscale); /* Firefox 3.5+ */
      filter: gray; /* IE5+ */
      -webkit-filter: grayscale(1); /* Webkit Nightlies & Chrome Canary */
      -webkit-transition: all .5s ease-in-out;
    }

    img.color_flip:hover {
      filter: none;
      -webkit-filter: grayscale(0);
      -webkit-transform: scale(1.1);
    }

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

built on dmark's answer to get the following, which is useful if you want the equiv of sprintf and hopefully will help someone...

def sprint(object):
    result = ''
    for i in [v for v in dir(object) if not callable(getattr(object, v)) and v[0] != '_']:
        result += '\n%s:' % i + str(getattr(object, i, ''))
    return result

byte[] data; using(Stream inputStream=file.InputStream) { MemoryStream memoryStream = inputStream as MemoryStream; if (memoryStream == null) { memoryStream = new MemoryStream(); inputStream.CopyTo(memoryStream); } data = memoryStream.ToArray(); }

I think this works, too:

int power = 1;
while(power < x)
    power*=2;

And the answer is power.

package-lock.json: It contains the exact version details that is currently installed for your Application.

You don't need a class, an object or a companion object for declaring constants in Kotlin. You can just declare a file holding all the constants (for example Constants.kt or you can also put them inside any existing Kotlin file) and directly declare the constants inside the file. The constants known at compile time must be marked with const.

So, in this case, it should be:

const val MY_CONST = "something"

and then you can import the constant using:

import package_name.MY_CONST

If you recently changed the password associated with the service account:

1. Start SQL Server Configuration Manager.
2. Select SQL Server Services in the left pane.
3. Right click the service you are trying to start in the right pane and click Properties.
4. Enter the new Password and Confirm password.

If you have no opportunity to change name="submit" you can also submit form this way:

function submitForm(form) {
    const submitFormFunction = Object.getPrototypeOf(form).submit;
    submitFormFunction.call(form);
}

Can you change the if condition to this:

if (!is.na(comments[l])) print(comments[l]);

You can only check for NA values with is.na().

Addendum to @sjngm's answer:

They both also ignore whitespace:

var foo = "    3     ";
console.log(parseInt(foo)); // 3
console.log(Number(foo)); // 3

Are any other LoadModule commands referencing modules in the /usr/lib/httpd/modules folder? If so, you should be fine just adding LoadModule ssl_module /usr/lib/httpd/modules/mod_ssl.so to your conf file.

Otherwise, you'll want to copy the mod_ssl.so file to whatever directory the other modules are being loaded from and reference it there.

There's a great deal of research on this. Here's a quick summary.

Response Times: The 3 Important Limits

by Jakob Nielsen on January 1, 1993

Summary: There are 3 main time limits (which are determined by human perceptual abilities) to keep in mind when optimizing web and application performance.

Excerpt from Chapter 5 in my book Usability Engineering, from 1993:

The basic advice regarding response times has been about the same for thirty years [Miller 1968; Card et al. 1991]:

• 0.1 second is about the limit for having the user feel that the system is reacting instantaneously, meaning that no special feedback is necessary except to display the result.
• 1.0 second is about the limit for the user's flow of thought to stay uninterrupted, even though the user will notice the delay. Normally, no special feedback is necessary during delays of more than 0.1 but less than 1.0 second, but the user does lose the feeling of operating directly on the data.
• 10 seconds is about the limit for keeping the user's attention focused on the dialogue. For longer delays, users will want to perform other tasks while waiting for the computer to finish, so they should be given feedback indicating when the computer expects to be done. Feedback during the delay is especially important if the response time is likely to be highly variable, since users will then not know what to expect.

if var == 'stringone' or var == 'stringtwo':
    dosomething()

'is' is used to check if the two references are referred to a same object. It compare the memory address. Apparently, 'stringone' and 'var' are different objects, they just contains the same string, but they are two different instances of the class 'str'. So they of course has two different memory addresses, and the 'is' will return False.

I ran into this issue when trying to get to one of my companies intranet sites. Here is the solution I used:

1. enter about:config into the firefox address bar and agree to continue.
2. search for the preference named security.ssl.enable_ocsp_stapling.
3. double-click this item to change its value to false.

This will lower your security as you will be able to view sites with invalid certs. Firefox will still prompt you that the cert is invalid and you have the choice to proceed forward, so it was worth the risk for me.

Instead of defining: COLUMN_HEADINGS("columnHeadings")

Try defining it as: COLUMNHEADINGS("columnHeadings")

Then when you call getByName(String name) method, call it with the upper-cased String like this: getByName(myStringVariable.toUpperCase())

I had the same problem as you, and this worked for me.

Here is a working demo that I have prepared about it. http://jsfiddle.net/Hss5g/2/

and take a look at the getopt module. It works quite good for me!

try to change your method if you need to loop!

within the parent stored procedure, create a #temp table that contains the data that you need to process. Call the child stored procedure, the #temp table will be visible and you can process it, hopefully working with the entire set of data and without a cursor or loop.

this really depends on what this child stored procedure is doing. If you are UPDATE-ing, you can "update from" joining in the #temp table and do all the work in one statement without a loop. The same can be done for INSERT and DELETEs. If you need to do multiple updates with IFs you can convert those to multiple UPDATE FROM with the #temp table and use CASE statements or WHERE conditions.

When working in a database try to lose the mindset of looping, it is a real performance drain, will cause locking/blocking and slow down the processing. If you loop everywhere, your system will not scale very well, and will be very hard to speed up when users start complaining about slow refreshes.

Post the content of this procedure you want call in a loop, and I'll bet 9 out of 10 times, you could write it to work on a set of rows.

@Html.Partial("NameOfPartialView")

Problems - no way to get the number of strings automatically (that i know of).

There is a bog-standard way of doing this, which lots of people (including MS) define macros like arraysize for:

#define arraysize(ar)  (sizeof(ar) / sizeof(ar[0]))

You can combine the two functions; coerce to characters thence to numerics:

> fac <- factor(c("1","2","1","2"))
> as.numeric(as.character(fac))
[1] 1 2 1 2

"AND" does not work in my PHP code.

Server's version maybe?

"&&" works fine.

class Testclass
{
  public $testvar;

  function dosomething()
  {
    echo $this->testvar;
  }
}

$Testclass = new Testclass();
$Testclass->testvar = "another value";    
$Testclass->dosomething(); ////It will print "another value"

I know this is old question. But maybe this can help you

JSON string

var jsonStr = '{ "bool": true, "number": 123, "string": "foo bar" }';

Pretty Print JSON

JSON.stringify(JSON.parse(jsonStr), null, 2);

Minify JSON

JSON.stringify(JSON.parse(jsonStr));

There are many ways to check the size, but as a developer we dont have much access to query meta tables, I find this solution very easy (Note: if you are getting error message ORA-01653 ‘The ORA-01653 error is caused because you need to add space to a tablespace.’)

--1. Used Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "USED SPACE(IN GB)" FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME
--2. Free Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "FREE SPACE(IN GB)" FROM   USER_FREE_SPACE GROUP BY TABLESPACE_NAME

A simple recursive method using reduce from functools and the add operator on lists:

>>> from functools import reduce
>>> from operator import add
>>> flatten = lambda lst: [lst] if type(lst) is int else reduce(add, [flatten(ele) for ele in lst])
>>> flatten(l)
[1, 2, 3, 4, 5, 6, 7, 8, 9]

The function flatten takes in lst as parameter. It loops all the elements of lst until reaching integers (can also change int to float, str, etc. for other data types), which are added to the return value of the outermost recursion.

Recursion, unlike methods like for loops and monads, is that it is a general solution not limited by the list depth. For example, a list with depth of 5 can be flattened the same way as l:

>>> l2 = [[3, [1, 2], [[[6], 5], 4, 0], 7, [[8]], [9, 10]]]
>>> flatten(l2)
[3, 1, 2, 6, 5, 4, 0, 7, 8, 9, 10]

If you have an instance function (i.e. one that gets passed self) you can use self to get a reference to the class using self.__class__

For example in the code below tornado creates an instance to handle get requests, but we can get hold of the get_handler class and use it to hold a riak client so we do not need to create one for every request.

import tornado.web
import riak

class get_handler(tornado.web.requestHandler):
    riak_client = None

    def post(self):
        cls = self.__class__
        if cls.riak_client is None:
            cls.riak_client = riak.RiakClient(pb_port=8087, protocol='pbc')
        # Additional code to send response to the request ...
    

I know this is old, but if anyone else wants to know why they get incomplete json like above is because the ampersand & is a special character in URLs used to separate parameters.
In your data there is an ampersand in R&R. So the acc parameter ends when it reaches the ampersand character.

That's why you are getting chopped data. The solution is either url encode the data or send as POST like the accepted solution suggests.

Can you try this?

Go to Tools> Preferences > Database > NLS and set the Date Format as MM/DD/YYYY HH24:MI:SS

This will gather all IPs on the host and filter out loopback/link-local and IPv6. This can also be edited to allow for IPv6 only, or both IPv4 and IPv6, as well as allowing loopback/link-local in IP list.

from socket import getaddrinfo, gethostname
import ipaddress

def get_ip(ip_addr_proto="ipv4", ignore_local_ips=True):
    # By default, this method only returns non-local IPv4 Addresses
    # To return IPv6 only, call get_ip('ipv6')
    # To return both IPv4 and IPv6, call get_ip('both')
    # To return local IPs, call get_ip(None, False)
    # Can combime options like so get_ip('both', False)

    af_inet = 2
    if ip_addr_proto == "ipv6":
        af_inet = 30
    elif ip_addr_proto == "both":
        af_inet = 0

    system_ip_list = getaddrinfo(gethostname(), None, af_inet, 1, 0)
    ip_list = []

    for ip in system_ip_list:
        ip = ip[4][0]

        try:
            ipaddress.ip_address(str(ip))
            ip_address_valid = True
        except ValueError:
            ip_address_valid = False
        else:
            if ipaddress.ip_address(ip).is_loopback and ignore_local_ips or ipaddress.ip_address(ip).is_link_local and ignore_local_ips:
                pass
            elif ip_address_valid:
                ip_list.append(ip)

    return ip_list

print(f"Your IP Address is: {get_ip()}")

Returns Your IP Address is: ['192.168.1.118']

If I run get_ip('both', False), it returns

Your IP Address is: ['::1', 'fe80::1', '127.0.0.1', '192.168.1.118', 'fe80::cb9:d2dd:a505:423a']

My most regular listens are:

• Java Posse
• Software Engineering Radio
• Stack Overflow
• Agile Toolkit Podcast (intermittent)

Also, if you haven't heard the OOPSLA 2007 podcasts (keynote/main sessions recorded and podcasted) they're definitely worth a listen, although it's a fairly short run.

You will need two things. The first is @media screen to activate the specific code at a certain screen size, used for responsive design. The second is the use of the visibility: hidden attribute. Once the browser/screen reaches 600pixels then #title_message will become hidden.

@media screen and (max-width: 600px) {
  #title_message {
    visibility: hidden;
    clear: both;
    float: left;
    margin: 10px auto 5px 20px;
    width: 28%;
    display: none;
  }
}

EDIT: if you are using another CSS for mobile then just add the visibility: hidden; to #title_message. Hope this helps you!

1. Checkout your branch and count quantity of all your commits.
2. Open git bash and write: git rebase -i HEAD~<quantity of your commits> (i.e. git rebase -i HEAD~5)
3. In opened txt file change pick keyword to squash for all commits, except first commit (which is on the top). For top one change it to reword (which means you will provide a new comment for this commit in the next step) and click SAVE! If in vim, press esc then save by entering wq! and press enter.
4. Provide Comment.
5. Open Git and make "Fetch all" to see new changes.

Done

I too faced this problem.

OS : Ubuntu 18.04 LTS

I'm using gnome, I switched from Gnome environment to Gnome Classic environment while logging in and it fixed the issue.

(You can also try other environments like unity - In my case this bug did not appear in Unity or Ubuntu, it only appeared in Gnome )

I have been using this successfully, where x and y are array-like.

def rsquared(x, y):
    """ Return R^2 where x and y are array-like."""

    slope, intercept, r_value, p_value, std_err = scipy.stats.linregress(x, y)
    return r_value**2

Ajay,

The reason that you can't see the other tables is that you need to log in as 'root' in order to see them

mysql -h localhost -u root

You can use the new Object.fromEntries() method.

Example:

const array = [_x000D_
   {key: 'a', value: 'b', redundant: 'aaa'},_x000D_
   {key: 'x', value: 'y', redundant: 'zzz'}_x000D_
]_x000D_
_x000D_
const hash = Object.fromEntries(_x000D_
   array.map(e => [e.key, e.value])_x000D_
)_x000D_
_x000D_
console.log(hash) // {a: b, x: y}

In my case, restarting apache fixed the problem. for Ubuntu / Debian:

sudo service apache2 restart

Go to your db -> structure and do empty in required table. See here:

There is some edge case that maybe will be helpful for someone:

There is an option that you will have postgres.pid filled with some PID. If you restart your machine, and before PostgreSQL will be back again, some other process will take that PID.

If that will happen, both the pg_ctl status and brew service are asked about the PostgreSQL status, will tell you that it is up.

Just do ps aux | grep <yourPID> and check if it is really PostgreSQL.

Just remember that with this method each console.log call will still do a call to a (empty) function causing overhead, if there are 100 console.log commands, you are still doing 100 calls to a blank function.

Not sure how much overhead this would cause, but there will be some, it would be preferable to have a flag to turn debug on then use something along the lines of:

var debug=true; if (debug) console.log('blah')

In the link you provided, thats not a loop in sql...

thats a loop in programming language

they are first getting list of all distinct districts, and then for each district executing query again.

This should do it:

elif var == 80 or var == 443 or 1024 <= var <= 65535:

Add a to-do item: Insert a comment with the prefix TODO:. For example: // TODO: [your to-do item].

Add a bug fix reminder: Insert a comment with the prefix FIXME:. For example: // FIXME: [your bug fix reminder].

Add a heading: Insert a comment with the prefix MARK:. For example: // MARK: [your section heading].

Add a separator line: To add a separator above an annotation, add a hyphen (-) before the comment portion of the annotation. For example: // MARK: - [your content]. To add a separator below an annotation, add a hyphen (-) after the comment portion of the annotation. For example: // MARK: [your content] -.

As of Laravel 5.2+, you can fetch it directly with $request->input('item') as well.

Retrieving JSON Input Values

When sending JSON requests to your application, you may access the JSON data via the input method as long as the Content-Type header of the request is properly set to application/json. You may even use "dot" syntax to dig deeper into JSON arrays:

$name = $request->input('user.name');

https://laravel.com/docs/5.2/requests

As noted above, the content-type header must be set to application/json so the jQuery ajax call would need to include contentType: "application/json",

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    dataType: "json",
    contentType: "application/json",
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

By fixing the AJAX call, $request->all() should work.

Refer to this example taken from - http://www.dzone.com/tutorials/java/log4j/sample-log4j-properties-file-configuration-1.html

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;

public class HelloWorld {

    static final Logger logger = Logger.getLogger(HelloWorld.class);
    static final String path = "src/resources/log4j.properties";

    public static void main(String[] args) {

        PropertyConfigurator.configure(path);
        logger.debug("Sample debug message");
        logger.info("Sample info message");
        logger.warn("Sample warn message");
        logger.error("Sample error message");
        logger.fatal("Sample fatal message");
    }
}

To change the logger levels - Logger.getRootLogger().setLevel(Level.INFO);

You can choose the url where the form must be posted (and thus, the invoked action) in different ways, depending on the browser support:

• for newer browsers that support HTML5, you can use formaction attribute of a submit button
• for older browsers that don't support this, you need to use some JavaScript that changes the form's action attribute, when the button is clicked, and before submitting

In this way you don't need to do anything special on the server side.

Of course, you can use Url extensions methods in your Razor to specify the form action.

For browsers supporting HMTL5: simply define your submit buttons like this:

<input type='submit' value='...' formaction='@Url.Action(...)' />

For older browsers I recommend using an unobtrusive script like this (include it in your "master layout"):

$(document).on('click', '[type="submit"][data-form-action]', function (event) {
  var $this = $(this);
  var formAction = $this.attr('data-form-action');
  $this.closest('form').attr('action', formAction);
});

NOTE: This script will handle the click for any element in the page that has type=submit and data-form-action attributes. When this happens, it takes the value of data-form-action attribute and set the containing form's action to the value of this attribute. As it's a delegated event, it will work even for HTML loaded using AJAX, without taking extra steps.

Then you simply have to add a data-form-action attribute with the desired action URL to your button, like this:

<input type='submit' data-form-action='@Url.Action(...)' value='...'/>

Note that clicking the button changes the form's action, and, right after that, the browser posts the form to the desired action.

As you can see, this requires no custom routing, you can use the standard Url extension methods, and you have nothing special to do in modern browsers.

I am posting a new answer, as I do not have enough reputation to comment on the one provided by Antonio (see: https://stackoverflow.com/a/1957777).

In case you want the SOAP message to be printed in a file (e.g. via Log4j), you may use:

OutputStream os = new ByteArrayOutputStream();
javax.xml.soap.SOAPMessage soapMsg = context.getMessage();
soapMsg.writeTo(os);
Logger LOG = Logger.getLogger(SOAPLoggingHandler.class); // Assuming SOAPLoggingHandler is the class name
LOG.info(os.toString());

Please note that under certain circumstances, the method call writeTo() may not behave as expected (see: https://community.oracle.com/thread/1123104?tstart=0 or https://www.java.net/node/691073), therefore the following code will do the trick:

javax.xml.soap.SOAPMessage soapMsg = context.getMessage();
com.sun.xml.ws.api.message.Message msg = new com.sun.xml.ws.message.saaj.SAAJMessage(soapMsg);
com.sun.xml.ws.api.message.Packet packet = new com.sun.xml.ws.api.message.Packet(msg);
Logger LOG = Logger.getLogger(SOAPLoggingHandler.class); // Assuming SOAPLoggingHandler is the class name
LOG.info(packet.toString());

Set the minOccurs attribute to 0 in the schema like so:

<?xml version="1.0"?>
  <xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
    <xs:element name="request">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="amenity">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="description" type="xs:string" minOccurs="0" />
                        </xs:sequence>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element> </xs:schema>

Here is a way to translate the whole tree into a single (not necessarily too human-readable) python expression using the SKompiler library:

from skompiler import skompile
skompile(dtree.predict).to('python/code')

Use the "MMMM" custom format specifier:

DateTime.Now.ToString("MMMM");

Solutions which are described above, even with unique CookieFile names, can cause a lot of problems on scale.

We had to serve a lot of authentications with this solution and our server went down because of high file read write actions.

The solution for this was to use Apache Reverse Proxy and omit CURL requests at all.

Details how to use Proxy on Apache can be found here: https://httpd.apache.org/docs/2.4/howto/reverse_proxy.html

you should do import Map from './Map' React is just telling you it doesn't know where variable you are importing is.

The original question was how to tell if a variable was numeric, not if it "has a numeric value".

There are a few operators that have separate modes of operation for numeric and string operands, where "numeric" means anything that was originally a number or was ever used in a numeric context (e.g. in $x = "123"; 0+$x, before the addition, $x is a string, afterwards it is considered numeric).

One way to tell is this:

if ( length( do { no warnings "numeric"; $x & "" } ) ) {
    print "$x is numeric\n";
}

If the bitwise feature is enabled, that makes & only a numeric operator and adds a separate string &. operator, you must disable it:

if ( length( do { no if $] >= 5.022, "feature", "bitwise"; no warnings "numeric"; $x & "" } ) ) {
    print "$x is numeric\n";
}

(bitwise is available in perl 5.022 and above, and enabled by default if you use 5.028; or above.)

Open atom editor and then press Alt and menu bar will appear. Now click on View tab and then click on Toggle Menu Bar as seen on this screenshot.

If you want to change tabs to spaces in a lot of files, but don't want to open them individually, I have found that it works equally as well to just use the Find and Replace option from the left-most tools bar.

In the first box (Find), copy and paste a tab from the source code.

In the second box (Replace), enter the number of spaces that you wish to use (i.e. 2 or 4).

If you press the ... button, you can specify directories to include or ignore (i.e. src/Data/Json).

Finally, inspect the result preview and press Replace All. All files in the workspace may be affected.

If the current directory is empty, then this will work:

git clone <repository> foo; mv foo/* foo/.git* .; rmdir foo

Alternatively, if you just want to convert one particular row to uppercase, use the code below:

df[[1]] <- toupper(df[[1]])

MSSQL requires that variables within procedures be DECLAREd and folks use the @Variable syntax (DECLARE @TEXT VARCHAR(25) = 'text'). Also, MS allows for declares within any block in the procedure, unlike mySQL which requires all the DECLAREs at the top.

While good on the command line, I feel using the "set = @variable" within stored procedures in mySQL is risky. There is no scope and variables live across scope boundaries. This is similar to variables in JavaScript being declared without the "var" prefix, which are then the global namespace and create unexpected collisions and overwrites.

I am hoping that the good folks at mySQL will allow DECLARE @Variable at various block levels within a stored procedure. Notice the @ (at sign). The @ sign prefix helps to separate variable names from table column names - as they are often the same. Of course, one can always add an "v" or "l_" prefix, but the @ sign is a handy and succinct way to have the variable name match the column you might be extracting the data from without clobbering it.

MySQL is new to stored procedures and they have done a good job for their first version. It will be a pleaure to see where they take it form here and to watch the server side aspects of the language mature.

Could someone explain to me, how to call the move method with the variable RIGHT

>>> myMissile = MissileDevice(myBattery)  # looks like you need a battery, don't know what that is, you figure it out.
>>> myMissile.move(MissileDevice.RIGHT)

If you have programmed in any other language with classes, besides python, this sort of thing

class Foo:
    bar = "baz"

is probably unfamiliar. In python, the class is a factory for objects, but it is itself an object; and variables defined in its scope are attached to the class, not the instances returned by the class. to refer to bar, above, you can just call it Foo.bar; you can also access class attributes through instances of the class, like Foo().bar.

Im utterly baffled about what 'self' refers too,

>>> class Foo:
...     def quux(self):
...         print self
...         print self.bar
...     bar = 'baz'
...
>>> Foo.quux
<unbound method Foo.quux>
>>> Foo.bar
'baz'
>>> f = Foo()
>>> f.bar
'baz'
>>> f
<__main__.Foo instance at 0x0286A058>
>>> f.quux
<bound method Foo.quux of <__main__.Foo instance at 0x0286A058>>
>>> f.quux()
<__main__.Foo instance at 0x0286A058>
baz
>>>

When you acecss an attribute on a python object, the interpreter will notice, when the looked up attribute was on the class, and is a function, that it should return a "bound" method instead of the function itself. All this does is arrange for the instance to be passed as the first argument.

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

There are a number of tools available which help debugging segmentation faults and I would like to add my favorite tool to the list: Address Sanitizers (often abbreviated ASAN).

Modern¹ compilers come with the handy -fsanitize=address flag, adding some compile time and run time overhead which does more error checking.

According to the documentation these checks include catching segmentation faults by default. The advantage here is that you get a stack trace similar to gdb's output, but without running the program inside a debugger. An example:

int main() {
  volatile int *ptr = (int*)0;
  *ptr = 0;
}

$ gcc -g -fsanitize=address main.c
$ ./a.out

The output is slightly more complicated than what gdb would output but there are upsides:

• There is no need to reproduce the problem to receive a stack trace. Simply enabling the flag during development is enough.

• ASANs catch a lot more than just segmentation faults. Many out of bounds accesses will be caught even if that memory area was accessible to the process.

¹ That is Clang 3.1+ and GCC 4.8+.

while running:
    lenli = len(li)
    for i, elem in enumerate(li):
        thiselem = elem
        nextelem = li[(i+1)%lenli]

Three things to be followed and make sure:

1. Whether multiple queries show lost connection?
2. how you use set query in MySQL?
3. how delete + update query simultaneously?

Answers:

1. Always try to remove definer as MySQL creates its own definer and if multiple tables involved for updation try to make a single query as sometimes multiple query shows lost connection
2. Always SET value at the top but after DELETE if its condition doesn't involve SET value.
3. Use DELETE FIRST THEN UPDATE IF BOTH OF THEM OPERATIONS ARE PERFORMED ON DIFFERENT TABLES

To restart a running service:

net stop "service name" && net start "service name"

However, if you don't know if the service is running in the first place and want to restart or start it, use this:

net stop "service name" & net start "service name"

This works if the service is already running or not.

For reference, here is the documentation on conditional processing symbols.

You can use stri_paste function with collapse parameter from stringi package like this:

stri_paste(letters, collapse='')
## [1] "abcdefghijklmnopqrstuvwxyz" 

And some benchmarks:

require(microbenchmark)
test <- stri_rand_lipsum(100)
microbenchmark(stri_paste(test, collapse=''), paste(test,collapse=''), do.call(paste, c(as.list(test), sep="")))
Unit: microseconds

Swift version of @Nicolas Bonnet 's answer:

    var popupWindow: UIWindow?

func showViewController(controller: UIViewController) {
    self.popupWindow = UIWindow(frame: UIScreen.mainScreen().bounds)
    controller.view.frame = self.popupWindow!.bounds
    self.popupWindow!.rootViewController = controller
    self.popupWindow!.makeKeyAndVisible()
}

func viewControllerDidRemove() {
    self.popupWindow?.removeFromSuperview()
    self.popupWindow = nil
}

Don't forget that the window must be a strong property, because the original answer leads to an immediate deallocation of the window

I found this question while looking for "how to pretty print html"

Using some of the ideas in this thread I adapted the XML solutions to work for XML or HTML:

from xml.dom.minidom import parseString as string_to_dom

def prettify(string, html=True):
    dom = string_to_dom(string)
    ugly = dom.toprettyxml(indent="  ")
    split = list(filter(lambda x: len(x.strip()), ugly.split('\n')))
    if html:
        split = split[1:]
    pretty = '\n'.join(split)
    return pretty

def pretty_print(html):
    print(prettify(html))

When used this is what it looks like:

html = """\
<div class="foo" id="bar"><p>'IDK!'</p><br/><div class='baz'><div>
<span>Hi</span></div></div><p id='blarg'>Try for 2</p>
<div class='baz'>Oh No!</div></div>
"""

pretty_print(html)

Which returns:

<div class="foo" id="bar">
  <p>'IDK!'</p>
  <br/>
  <div class="baz">
    <div>
      <span>Hi</span>
    </div>
  </div>
  <p id="blarg">Try for 2</p>
  <div class="baz">Oh No!</div>
</div>

add or remove fragment in viewpager dynamically.
Call setupViewPager(viewPager) on activity start. To load different fragment call setupViewPagerCustom(viewPager). e.g. on button click call: setupViewPagerCustom(viewPager);

    private void setupViewPager(ViewPager viewPager)
{
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
    adapter.addFrag(new fragmnet1(), "HOME");
    adapter.addFrag(new fragmnet2(), "SERVICES");

    viewPager.setAdapter(adapter);
}

private void setupViewPagerCustom(ViewPager viewPager)
{

    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());

    adapter.addFrag(new fragmnet3(), "Contact us");
    adapter.addFrag(new fragmnet4(), "ABOUT US");


    viewPager.setAdapter(adapter);
}

//Viewpageradapter, handles the views

static class ViewPagerAdapter extends FragmentStatePagerAdapter
{
    private final List<Fragment> mFragmentList = new ArrayList<>();
    private final List<String> mFragmentTitleList = new ArrayList<>();

    public ViewPagerAdapter(FragmentManager manager){
        super(manager);
    }

    @Override
    public Fragment getItem(int position) {
        return mFragmentList.get(position);
    }

    @Override
    public int getCount() {
        return mFragmentList.size();
    }

    @Override
    public int getItemPosition(Object object){
        return PagerAdapter.POSITION_NONE;
    }

    public void addFrag(Fragment fragment, String title){
        mFragmentList.add(fragment);
        mFragmentTitleList.add(title);
    }

    @Override
    public CharSequence getPageTitle(int position){
        return mFragmentTitleList.get(position);
    }
}

You can easily convert the string data type to numerical data type.
Don't forget to change collectionName & FieldName.
for ex : CollectionNmae : Users & FieldName : Contactno.

Try this query..

db.collectionName.find().forEach( function (x) {
x.FieldName = parseInt(x.FieldName);
db.collectionName.save(x);
});

There are various replacement "malloc" libraries out there that will allow you to call a function at the end and it will tell you about all the unfreed memory, and in many cases, who malloced (or new'ed) it in the first place.

Here is an example which answers the question of returning the parameters of a class. Moreover, it still respects the chain of inheritance, i.e. only the parameters of the class itself are returned. The function get_params is added as a simple example, but other functionalities can be added thanks to the inspect module.

import inspect 

class Parent:
    @classmethod
    def get_params(my_class):
        return list(inspect.signature(my_class).parameters.keys())

class OtherParent:
    def __init__(self, a, b, c):
        pass

class Child(Parent, OtherParent):
    def __init__(self, x, y, z):
        pass

print(Child.get_params())
>>['x', 'y', 'z']

You are missing a parameter in the command. It should be in this order:

composer create-project [PACKAGE] [DESTINATION PATH] [--FLAGS]

You're mistakingly specifying your local path as the Composer/Packagist package you wish to create a project from. Hence the "Could not find package" message.

Simply make sure you're specifying the Laravel package and you should be good to go:

composer create-project laravel/laravel /Applications/MAMP/htdocs/test_laravel

The answer is a simple PowerShell one-liner:

Get-WmiObject Win32_NetworkConnection | ft "RemoteName","LocalName" -A

If you only want to pull the UNC for one particular drive, add a where statement:

Get-WmiObject Win32_NetworkConnection | where -Property 'LocalName' -eq 'Z:'  | ft "RemoteName","LocalName" -A

I had the same issue, I changed the ports, restarted the services but in vein, only worked for me when I updated the Microsoft Visual c++ files

if you want to completely empty the database and not just delete a model or models attached to it you can do:

rake db:purge

you can also do it on the test database

rake db:test:purge

Not that I recommend placing JavaScript directly into HTML, but this works in modern browsers (not IE11) to disable all submit buttons after a form submits:

<form onsubmit="this.querySelectorAll('[type=submit]').forEach(b => b.disabled = true)">

None of the above solutions handled deep nested params with just jQuery, so here is my two cents solution.

If you're using jQuery and you need to handle deep nested parameters, you can use this function below:

    /**
     * Original code found here: https://github.com/mgalante/jquery.redirect/blob/master/jquery.redirect.js
     * I just simplified it for my own taste.
     */
    function postForm(parameters, url) {

        // generally we post the form with a blank action attribute
        if ('undefined' === typeof url) {
            url = '';
        }


        //----------------------------------------
        // SOME HELPER FUNCTIONS
        //----------------------------------------
        var getForm = function (url, values) {

            values = removeNulls(values);

            var form = $('<form>')
                .attr("method", 'POST')
                .attr("action", url);

            iterateValues(values, [], form, null);
            return form;
        };

        var removeNulls = function (values) {
            var propNames = Object.getOwnPropertyNames(values);
            for (var i = 0; i < propNames.length; i++) {
                var propName = propNames[i];
                if (values[propName] === null || values[propName] === undefined) {
                    delete values[propName];
                } else if (typeof values[propName] === 'object') {
                    values[propName] = removeNulls(values[propName]);
                } else if (values[propName].length < 1) {
                    delete values[propName];
                }
            }
            return values;
        };

        var iterateValues = function (values, parent, form, isArray) {
            var i, iterateParent = [];
            Object.keys(values).forEach(function (i) {
                if (typeof values[i] === "object") {
                    iterateParent = parent.slice();
                    iterateParent.push(i);
                    iterateValues(values[i], iterateParent, form, Array.isArray(values[i]));
                } else {
                    form.append(getInput(i, values[i], parent, isArray));
                }
            });
        };

        var getInput = function (name, value, parent, array) {
            var parentString;
            if (parent.length > 0) {
                parentString = parent[0];
                var i;
                for (i = 1; i < parent.length; i += 1) {
                    parentString += "[" + parent[i] + "]";
                }

                if (array) {
                    name = parentString + "[" + name + "]";
                } else {
                    name = parentString + "[" + name + "]";
                }
            }

            return $("<input>").attr("type", "hidden")
                .attr("name", name)
                .attr("value", value);
        };


        //----------------------------------------
        // NOW THE SYNOPSIS
        //----------------------------------------
        var generatedForm = getForm(url, parameters);

        $('body').append(generatedForm);
        generatedForm.submit();
        generatedForm.remove();
    }

Here is an example of how to use it. The html code:

<button id="testButton">Button</button>

<script>
    $(document).ready(function () {
        $("#testButton").click(function () {
            postForm({
                csrf_token: "abcd",
                rows: [
                    {
                        user_id: 1,
                        permission_group_id: 1
                    },
                    {
                        user_id: 1,
                        permission_group_id: 2
                    }
                ],
                object: {
                    apple: {
                        color: "red",
                        age: "23 days",
                        types: [
                            "golden",
                            "opal",
                        ]
                    }
                },
                the_null: null, // this will be dropped, like non-checked checkboxes are dropped
            });
        });
    });
</script>

And if you click the test button, it will post the form and you will get the following values in POST:

array(3) {
  ["csrf_token"] => string(4) "abcd"
  ["rows"] => array(2) {
    [0] => array(2) {
      ["user_id"] => string(1) "1"
      ["permission_group_id"] => string(1) "1"
    }
    [1] => array(2) {
      ["user_id"] => string(1) "1"
      ["permission_group_id"] => string(1) "2"
    }
  }
  ["object"] => array(1) {
    ["apple"] => array(3) {
      ["color"] => string(3) "red"
      ["age"] => string(7) "23 days"
      ["types"] => array(2) {
        [0] => string(6) "golden"
        [1] => string(4) "opal"
      }
    }
  }
}

Note: if you want to post the form to another url than the current page, you can specify the url as the second argument of the postForm function.

So for instance (to re-use your example):

postForm({'q':'a'}, 'http://example.com/');

Hope this helps.

Note2: the code was taken from the redirect plugin. I basically just simplified it for my needs.

I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

INCLUDE_DIRECTORIES(your/header/dir)
LINK_DIRECTORIES(your/library/dir)
rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)

note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them

So it depends on how you want to pick the incrementer, but this should work:

Range("A1:" & Cells(1, i).Address).Select

Where i is the variable that represents the column you want to select (1=A, 2=B, etc.). Do you want to do this by column letter instead? We can adjust if so :)

If you want the beginning to be dynamic as well, you can try this:

Sub SelectCols()

    Dim Col1 As Integer
    Dim Col2 As Integer

    Col1 = 2
    Col2 = 4

    Range(Cells(1, Col1), Cells(1, Col2)).Select

End Sub

dev.off() is the best function, but it clears also all plots. If you want to keep plots in your window, at the beginning save default par settings:

def.par = par()

Then when you use your par functions you still have a backup of default par settings. Later on, after generating plots, finish with:

par(def.par) #go back to default par settings

With this, you keep generated plots and reset par settings.

class Test {
    public function yo() {
        return 'yoes';
    }
}

$var = 'Test';

$obj = new $var();
echo $obj->yo(); //yoes

I found this post which suggested to have two separate IP addresses so that both could listen on port 80.

There was a caveat that you had to make a change in IIS because of socket pooling. Here are the instructions based on the link above:

1. Extract the httpcfg.exe utility from the support tools area on the Win2003 CD.
2. Stop all IIS services: net stop http /y
3. Have IIS listen only on the IP address I'd designated for IIS: httpcfg set iplisten -i 192.168.1.253
4. Make sure: httpcfg query iplisten (The IPs listed are the only IP addresses that IIS will be listening on and no other.)
5. Restart IIS Services: net start w3svc
6. Start the Apache service

Have you tried it?

If you do:

var HI = 'Hello World';

In global.js. And then do:

alert(HI);

In js1.js it will alert it fine. You just have to include global.js prior to the rest in the HTML document.

The only catch is that you have to declare it in the window's scope (not inside any functions).

You could just nix the var part and create them that way, but it's not good practice.

code:

TextView your_text_view = (TextView) findViewById(R.id.your_id_textview);
your_text_view.setEllipsize(TextUtils.TruncateAt.END);

xml:

android:maxLines = "5"

e.g.

In Matthew 13, the disciples asked Jesus why He spoke to the crowds in parables. He answered, "It has been given to you to know the mysteries of the kingdom of heaven, but to them it has not been given.

Output: In Matthew 13, the disciples asked Jesus why He spoke to the crowds in parables. He answered, "It has been given to you to know...

A very simple method would be to use the extract method to select all the digits. Simply supply it the regular expression '\d+' which extracts any number of digits.

df['result'] = df.result.str.extract(r'(\d+)', expand=True).astype(int)
df

    time  result
1  09:00      52
2  10:00      62
3  11:00      44
4  12:00      30
5  13:00     110

To find the distance between 2 points, you need to find the length of the hypotenuse in a right angle triangle with a width and height equal to the vertical and horizontal distance:

Math.hypot(endX - startX, endY - startY)

Don't try to be too sneaky, especially when it needlessly affects performance. If you really have a whole heap of comparisons to do, just format it nicely.

if (foobar === foo ||
    foobar === bar ||
    foobar === baz ||
    foobar === pew) {
     //do something
}

I have 2 accounts on github, and here is what I did (on linux) to make it work.

Keys

• Create 2 pair of rsa keys, via ssh-keygen, name them properly, so that make life easier.
• Add private keys to local agent via ssh-add path_to_private_key
• For each github account, upload a (distinct) public key.

Configuration

~/.ssh/config

Host github-kc
    Hostname        github.com
    User git
    IdentityFile    ~/.ssh/github_rsa_kc.pub
    # LogLevel DEBUG3

Host github-abc
    Hostname        github.com
    User git
    IdentityFile    ~/.ssh/github_rsa_abc.pub
    # LogLevel DEBUG3

Set remote url for repo:

• For repo in Host github-kc:

  git remote set-url origin git@github-kc:kuchaguangjie/pygtrans.git
  

• For repo in Host github-abc:

  git remote set-url origin git@github-abc:abcdefg/yyy.git
  

Explaination

Options in ~/.ssh/config:

• Host github-<identify_specific_user>
  Host could be any value that could identify a host plus an account, it don't need to be a real host, e.g github-kc identify one of my account on github for my local laptop,
  

  When set remote url for a git repo, this is the value to put after git@, that's how a repo maps to a Host, e.g git remote set-url origin git@github-kc:kuchaguangjie/pygtrans.git

• 
  
• [Following are sub options of Host]
• Hostname
  specify the actual hostname, just use github.com for github,
• User git
  the user is always git for github,
• IdentityFile
  specify key to use, just put the path the a public key,
• LogLevel
  specify log level to debug, if any issue, DEBUG3 gives the most detailed info.

If you get this error while uploading files in Sub domain And working correct in your localhost, then follow below steps:

Solution:

Plesk Panel

• Login to your Plesk Panel. Select Your Sub domain which is giving error.
• Click on Hosting settings.
• Select Additional write/modify permissions and Apply.

CPanel

• I am not sure about options available in CPanel. But IF you give permission to directory (In CPanel it has to be decimal number like 777, 755) will resolve the error.

For more details refer here

Reason for Error:

• Let's Assume FileUpload.SaveAs(Server.MapPath("~/uploads/" + *YOUR_FILENAME*)) will be your code to move your files to upload path.

• Server.MapPath will give you physical path (Real Path) of directory. But your Sub domain may don't have permission for access physical path.

• So, If you give permission for sub domain to access write/modify permission, it will resolve the issue.

Just before I go into detail about how you can access the state of a child component, please make sure to read Markus-ipse's answer regarding a better solution to handle this particular scenario.

If you do indeed wish to access the state of a component's children, you can assign a property called ref to each child. There are now two ways to implement references: Using React.createRef() and callback refs.

Using React.createRef()

This is currently the recommended way to use references as of React 16.3 (See the docs for more info). If you're using an earlier version then see below regarding callback references.

You'll need to create a new reference in the constructor of your parent component and then assign it to a child via the ref attribute.

class FormEditor extends React.Component {
  constructor(props) {
    super(props);
    this.FieldEditor1 = React.createRef();
  }
  render() {
    return <FieldEditor ref={this.FieldEditor1} />;
  }
}

In order to access this kind of ref, you'll need to use:

const currentFieldEditor1 = this.FieldEditor1.current;

This will return an instance of the mounted component so you can then use currentFieldEditor1.state to access the state.

Just a quick note to say that if you use these references on a DOM node instead of a component (e.g. <div ref={this.divRef} />) then this.divRef.current will return the underlying DOM element instead of a component instance.

Callback Refs

This property takes a callback function that is passed a reference to the attached component. This callback is executed immediately after the component is mounted or unmounted.

For example:

<FieldEditor
    ref={(fieldEditor1) => {this.fieldEditor1 = fieldEditor1;}
    {...props}
/>

In these examples the reference is stored on the parent component. To call this component in your code, you can use:

this.fieldEditor1

and then use this.fieldEditor1.state to get the state.

One thing to note, make sure your child component has rendered before you try to access it ^_^

As above, if you use these references on a DOM node instead of a component (e.g. <div ref={(divRef) => {this.myDiv = divRef;}} />) then this.divRef will return the underlying DOM element instead of a component instance.

Further Information

If you want to read more about React's ref property, check out this page from Facebook.

Make sure you read the "Don't Overuse Refs" section that says that you shouldn't use the child's state to "make things happen".

Hope this helps ^_^

Edit: Added React.createRef() method for creating refs. Removed ES5 code.

Having is only used with aggregation but where with non aggregation statements If you have where word put it before aggregation (group by)

To use % instead of px or em with @Gaurav's answer, it's just

<div class="home-component" [style.width.%]="80" [style.height.%]="95">
Some stuff in this div</div>

The code

Private Sub Worksheet_Activate()
    Dim PvtTbl As PivotTable
        Cells.EntireColumn.AutoFit
        For Each PvtTbl In Worksheets("Sales Details").PivotTables
        PvtTbl.RefreshTable
        Next
End Sub 

works fine.

The code is used in the activate sheet module, thus it displays a flicker/glitch when the sheet is activated.

I know that this question is a little old, but I thought that I would provide an alternative which, in my opinion, might be a little easier. If you're willing to add "temporary" columns to a data set, you can use Excel's Analysis ToolPak?Data Analysis?Regression. The secret to doing a quadratic or a cubic regression analysis is defining the Input X Range:.

If you're doing a simple linear regression, all you need are 2 columns, X & Y. If you're doing a quadratic, you'll need X_1, X_2, & Y where X_1 is the x variable and X_2 is x^2; likewise, if you're doing a cubic, you'll need X_1, X_2, X_3, & Y where X_1 is the x variable, X_2 is x^2 and X_3 is x^3. Notice how the Input X Range is from A1 to B22, spanning 2 columns.

The following image the output of the regression analysis. I've highlighted the common outputs, including the R-Squared values and all the coefficients.

I had the same problem. You need to go and add an app password for sourcetree in your bitbucket settings. Click "Bitbucket settings" in menu, App passwords, create app password. Then go to SourceTree and edit your saved password

Based off your code, i created this Fiddle
You need to use

var cb = document.getElementsByName('field206451')[0];
var label = document.getElementsByName('label206451')[0];

if you want to use name attributes then you have to take the index since it is a list of items, not just a single one. Everything else worked good.

If you are using Spark, use the following to get the Spark version:

spark-submit --version

or

Login to the Cloudera Manager and goto Hosts page then run inspect hosts in cluster

In the RC you can also extract route data like the action method name like this

ViewContext.Controller.ValueProvider["action"].RawValue
ViewContext.Controller.ValueProvider["controller"].RawValue
ViewContext.Controller.ValueProvider["id"].RawValue

Update for MVC 3

ViewContext.Controller.ValueProvider.GetValue("action").RawValue
ViewContext.Controller.ValueProvider.GetValue("controller").RawValue
ViewContext.Controller.ValueProvider.GetValue("id").RawValue

Update for MVC 4

ViewContext.Controller.RouteData.Values["action"]
ViewContext.Controller.RouteData.Values["controller"]
ViewContext.Controller.RouteData.Values["id"]

Update for MVC 4.5

ViewContext.RouteData.Values["action"]
ViewContext.RouteData.Values["controller"]
ViewContext.RouteData.Values["id"]

You could try to debug the problem using valgrind:

The Valgrind distribution currently includes six production-quality tools: a memory error detector, two thread error detectors, a cache and branch-prediction profiler, a call-graph generating cache profiler, and a heap profiler. It also includes two experimental tools: a heap/stack/global array overrun detector, and a SimPoint basic block vector generator. It runs on the following platforms: X86/Linux, AMD64/Linux, PPC32/Linux, PPC64/Linux, and X86/Darwin (Mac OS X).

What Time Zones?

No where in your question do you mention time zone. What time zone is implied that input string? What time zone do you want for your output? And, UTC is a time zone (or lack thereof depending on your mindset) not a string format.

ISO 8601

Your input string is in ISO 8601 format, except that it lacks an offset from UTC.

Joda-Time

Here is some example code in Joda-Time 2.3 to show you how to handle time zones. Joda-Time has built-in default formatters for parsing and generating String representations of date-time values.

String input = "2013-10-22T01:37:56";
DateTime dateTimeUtc = new DateTime( input, DateTimeZone.UTC );
DateTime dateTimeMontréal = dateTimeUtc.withZone( DateTimeZone.forID( "America/Montreal" );
String output = dateTimeMontréal.toString();

As for generating string representations in other formats, search StackOverflow for "Joda format".

This is not an error message but a warning. It is very clearly explained in their website as :

This warning, i.e. not an error, message is reported when no SLF4J providers could be found on the class path. Placing one (and only one) of slf4j-nop.jar slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem. Note that these providers must target slf4j-api 1.8 or later.

In the absence of a provider, SLF4J will default to a no-operation (NOP) logger provider.

Er ... how about in a boolean function to indicate 'not true'?

The atob function will decode a Base64-encoded string into a new string with a character for each byte of the binary data.

const byteCharacters = atob(b64Data);

Each character's code point (charCode) will be the value of the byte. We can create an array of byte values by applying this using the .charCodeAt method for each character in the string.

const byteNumbers = new Array(byteCharacters.length);
for (let i = 0; i < byteCharacters.length; i++) {
    byteNumbers[i] = byteCharacters.charCodeAt(i);
}

You can convert this array of byte values into a real typed byte array by passing it to the Uint8Array constructor.

const byteArray = new Uint8Array(byteNumbers);

This in turn can be converted to a BLOB by wrapping it in an array and passing it to the Blob constructor.

const blob = new Blob([byteArray], {type: contentType});

The code above works. However the performance can be improved a little by processing the byteCharacters in smaller slices, rather than all at once. In my rough testing 512 bytes seems to be a good slice size. This gives us the following function.

const b64toBlob = (b64Data, contentType='', sliceSize=512) => {
  const byteCharacters = atob(b64Data);
  const byteArrays = [];

  for (let offset = 0; offset < byteCharacters.length; offset += sliceSize) {
    const slice = byteCharacters.slice(offset, offset + sliceSize);

    const byteNumbers = new Array(slice.length);
    for (let i = 0; i < slice.length; i++) {
      byteNumbers[i] = slice.charCodeAt(i);
    }

    const byteArray = new Uint8Array(byteNumbers);
    byteArrays.push(byteArray);
  }

  const blob = new Blob(byteArrays, {type: contentType});
  return blob;
}

const blob = b64toBlob(b64Data, contentType);
const blobUrl = URL.createObjectURL(blob);

window.location = blobUrl;

Full Example:

const b64toBlob = (b64Data, contentType='', sliceSize=512) => {_x000D_
  const byteCharacters = atob(b64Data);_x000D_

Spring MVC is deeply integreated in Spring, Struts MVC is not.

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home

Because:

The documentation says that these two methods are equivalent:

StreamReader.Close: This implementation of Close calls the Dispose method passing a true value.

StreamWriter.Close: This implementation of Close calls the Dispose method passing a true value.

Stream.Close: This method calls Dispose, specifying true to release all resources.

So, both of these are equally valid:

/* Option 1, implicitly calling Dispose */
using (StreamWriter writer = new StreamWriter(filename)) { 
   // do something
} 

/* Option 2, explicitly calling Close */
StreamWriter writer = new StreamWriter(filename)
try {
    // do something
}
finally {
    writer.Close();
}

Personally, I would stick with the first option, since it contains less "noise".

In C++ NULL expands to 0 or 0L. See this quote from Stroustrup's FAQ:

Should I use NULL or 0?

In C++, the definition of NULL is 0, so there is only an aesthetic difference. I prefer to avoid macros, so I use 0. Another problem with NULL is that people sometimes mistakenly believe that it is different from 0 and/or not an integer. In pre-standard code, NULL was/is sometimes defined to something unsuitable and therefore had/has to be avoided. That's less common these days.

If you have to name the null pointer, call it nullptr; that's what it's called in C++11. Then, "nullptr" will be a keyword.

Try this from your AndroidTabRestaurantDescSearchListView activity

Intent intent  = new Intent(this,RatingDescriptionSearchActivity.class );
intent.putExtras( getIntent().getExtras() );
startActivity( intent );  

And then from RatingDescriptionSearchActivity activity just call

getIntent().getStringExtra("key")

Additionnally to hotkey's good answer, here is how I choose among the two in practice:

lateinit is for external initialisation: when you need external stuff to initialise your value by calling a method.

e.g. by calling:

private lateinit var value: MyClass

fun init(externalProperties: Any) {
   value = somethingThatDependsOn(externalProperties)
}

While lazy is when it only uses dependencies internal to your object.

If you want to wait for the executor service to finish executing, call shutdown() and then, awaitTermination(units, unitType), e.g. awaitTermination(1, MINUTE). The ExecutorService does not block on it's own monitor, so you can't use wait etc.

Funny the answer is hidden in among the answers.

str.replace("•", "something") 

would work if you use the right semantics.

str.replace(u"\u2022","something") 

works wonders ;) , thnx to RParadox for the hint.

Simply inside the loop write <?php the_post_thumbnail_url(); ?> as shown below:-

$args=array('post_type' => 'your_custom_post_type_slug','order' => 'DESC','posts_per_page'=> -1) ;
$the_qyery= new WP_Query($args);

if ($the_qyery->have_posts()) :
    while ( $the_qyery->have_posts() ) : $the_qyery->the_post();?>

<div class="col col_4_of_12">
    <div class="article_standard_view">
        <article class="item">
            <div class="item_header">
                <a href="<?php the_permalink(); ?>"><img src="<?php the_post_thumbnail_url(); ?>" alt="Post"></a>
            </div>

        </article>
    </div>
</div>            
<?php endwhile; endif; ?>

In linux shell, many commands accept multiple parameters and therefore could be used with wild cards. So, for example if you want to move all files from folder A to folder B, you write:

mv A/* B

If you want to move all files with a certain "look" to it, you could do like this:

mv A/*.txt B

Which copies all files that are blablabla.txt to folder B

Star (*) can substitute any number of characters or letters while ? can substitute one. For example if you have many files in the shape file_number.ext and you want to move only the ones that have two digit numbers, you could use a command like this:

mv A/file_??.ext B

Or more complicated examples:

mv A/fi*_??.e* B

For files that look like fi<-something->_<-two characters->.e<-something->

Unlike many commands in shell that require -R to (for example) copy or remove subfolders, mv does that itself.

Remember that mv overwrites without asking (unless the files being overwritten are read only or you don't have permission) so make sure you don't lose anything in the process.

For your future information, if you have subfolders that you want to copy, you could use the -R option, saying you want to do the command recursively. So it would look something like this:

cp A/* B -R

By the way, all I said works with rm (remove, delete) and cp (copy) too and beware, because once you delete, there is no turning back! Avoid commands like rm * -R unless you are sure what you are doing.

MySQL date format is this : Y-M-D. You are using Y/M/D. That's is wrong. modify your query.

If you insert the date like Y/M/D, It will be insert null value in the database.

If you are using PHP and date you are getting from the form is like this Y/M/D, you can replace this with using the statement .

out_date=date('Y-m-d', strtotime(str_replace('/', '-', $data["input_date"])))

As mentioned in other answers, It takes forever because the size of cocoapods master repo is huge. This time can be reduced using the following steps.

1) Create a private specs file path on your github repository. Provide this path https://github.com/yourpathForspecs.git' as a source in your podfile.

2) identify ALL the repositories You need and their dependencies( mentioned in the podspec.json file on cocoapods for these repositories) and get their podspec.json files from cocoapods. add these podspec.json files with their folder ( say the latest version folder for bolts) in this specs repository.

3) remove the source 'https://github.com/CocoaPods/Specs.git' in the podfile

4) pod update

This will take significantly less time as this requires fetching and downloading just the pods you need instead of whole cocoapods repository. In My case it reduced the pod update time from 15-20 mins on average to 3-4 mins at most.

Though the question appears to be demanding plotting a histogram using matplotlib.hist() function, it can arguably be not done using the same as the latter part of the question demands to use the given probabilities as the y-values of bars and given names(strings) as the x-values.

I'm assuming a sample list of names corresponding to given probabilities to draw the plot. A simple bar plot serves the purpose here for the given problem. The following code can be used:

import matplotlib.pyplot as plt
probability = [0.3602150537634409, 0.42028985507246375, 
  0.373117033603708, 0.36813186813186816, 0.32517482517482516, 
  0.4175257731958763, 0.41025641025641024, 0.39408866995073893, 
  0.4143222506393862, 0.34, 0.391025641025641, 0.3130841121495327, 
  0.35398230088495575]
names = ['name1', 'name2', 'name3', 'name4', 'name5', 'name6', 'name7', 'name8', 'name9',
'name10', 'name11', 'name12', 'name13'] #sample names
plt.bar(names, probability)
plt.xticks(names)
plt.yticks(probability) #This may be included or excluded as per need
plt.xlabel('Names')
plt.ylabel('Probability')

select 1 from table is used by some databases as a query to test a connection to see if it's alive, often used when retrieving or returning a connection to / from a connection pool.

My issue turned out to be that I had SSL Enabled on the project settings. I simply disabled this because I did not require SSL for running the project locally.

In Visual Studio 2015:

• Select the project in the Solution Explorer.
• In the Properties window set SSL Enabled to False.
• I was able to run the project.

In my situation I was getting an error about port 443 in use because this was the port set on the SSL URL for the project.

With jQuery inluded:

disable

$.fn.disableScroll = function() {
    window.oldScrollPos = $(window).scrollTop();

    $(window).on('scroll.scrolldisabler',function ( event ) {
       $(window).scrollTop( window.oldScrollPos );
       event.preventDefault();
    });
};

enable

$.fn.enableScroll = function() {
    $(window).off('scroll.scrolldisabler');
};

usage

//disable
$("#selector").disableScroll();
//enable
$("#selector").enableScroll();
