The pylab examples page is a very useful source. The example relevant for your question:

From the documentation, you can apparently use either command to keep the file in the project history. Looks like you want remove, since it also deletes the file from the working directory.

From the Mercurial book at http://hgbook.red-bean.com/read/:

Removing a file does not affect its history. It is important to understand that removing a file has only two effects. It removes the current version of the file from the working directory. It stops Mercurial from tracking changes to the file, from the time of the next commit. Removing a file does not in any way alter the history of the file.

The man page hg(1) says this about forget:

Mark the specified files so they will no longer be tracked after the next commit. This only removes files from the current branch, not from the entire project history, and it does not delete them from the working directory.

And this about remove:

Schedule the indicated files for removal from the repository. This only removes files from the current branch, not from the entire project history.

Here is probably the simplest way to go about it (with a reproducible example):

library(plyr)
df <- data.frame(ID=rep(1:3, 3), Obs_1=rnorm(9), Obs_2=rnorm(9), Obs_3=rnorm(9))
ddply(df, .(ID), summarize, Obs_1_mean=mean(Obs_1), Obs_1_std_dev=sd(Obs_1),
  Obs_2_mean=mean(Obs_2), Obs_2_std_dev=sd(Obs_2))

   ID  Obs_1_mean Obs_1_std_dev  Obs_2_mean Obs_2_std_dev
1  1 -0.13994642     0.8258445 -0.15186380     0.4251405
2  2  1.49982393     0.2282299  0.50816036     0.5812907
3  3 -0.09269806     0.6115075 -0.01943867     1.3348792

EDIT: The following approach saves you a lot of typing when dealing with many columns.

ddply(df, .(ID), colwise(mean))

Graph Theory Definitions

(In descending order of generality)

• Walk: a sequence of edges where the end of one edge marks the beginning of the next edge

• Trail: a walk which does not repeat any edges. All trails are walks.

• Path: a walk where each vertex is traversed at most once. (paths used to refer to open walks, the definition has changed now) The property of traversing vertices at most once means that edges are also crossed at most once, hence all paths are trails.

Hamiltonian paths & Eulerian trails

• Hamiltonian path: visits every vertex in the graph (exactly once, because it is a path)

• Eulerian trail: visits every edge in the graph exactly once (because it is a trail, vertices may well be crossed more than once.)

I'm not sure I understand completely, but you might be looking for the 'formatoptions' configuration setting. Try something like :set formatoptions-=t. The t option will insert line breaks to make text wrap at the width set by textwidth. You can also put this command in your .vimrc, just remove the colon (:).

Use $ before " " it will allow to write variables between these brackets

 Console.WriteLine($"{mon}.{da}.{yer}");

The pro way :

  Console.WriteLine($"{DateTime.Today.Month}.{DateTime.Today.Day}.{DateTime.Today.Year}");
  Console.WriteLine($"month{DateTime.Today.Month} day{DateTime.Today.Day} year{DateTime.Today.Year}");

You can use mplayer.

mencoder -nocache -rtsp-stream-over-tcp rtsp://192.168.XXX.XXX/test.sdp -oac copy -ovc copy -o test.avi

The "copy" codec is just a dumb copy of the stream. Mencoder adds a header and stuff you probably want.

In the mplayer source file "stream/stream_rtsp.c" is a prebuffer_size setting of 640k and no option to change the size other then recompile. The result is that writing the stream is always delayed, which can be annoying for things like cameras, but besides this, you get an output file, and can play it back most places without a problem.

The problem is you either haven't closed your if or you need an elseif:

create procedure checando(
    in nombrecillo varchar(30),
    in contrilla varchar(30), 
    out resultado int)
begin 

    if exists (select * from compas where nombre = nombrecillo and contrasenia = contrilla) then
        set resultado = 0;
    elseif exists (select * from compas where nombre = nombrecillo) then
        set resultado = -1;
    else 
        set resultado = -2;
    end if;
end;

You do not require jQuery for this, simply use the following CSS content:

li {cursor: pointer}

And voilà! Handy.

You just missed an extra pair of brackets for the "OR" symbol. The following should do the trick:

([0-9]+)\s+((\bseconds\b)|(\bminutes\b))

Without those you were either matching a number followed by seconds OR just the word minutes

you can wrap -Andrie answer into a generic function

mbind<-function(...){
 Reduce( function(x,y){cbind(x,y[match(row.names(x),row.names(y)),])}, list(...) )
}

Here, you can bind multiple frames with rownames as key

It is possible. Have a look at JSch.addIdentity(...)

This allows you to use key either as byte array or to read it from file.

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class UserAuthPubKey {
    public static void main(String[] arg) {
        try {
            JSch jsch = new JSch();

            String user = "tjill";
            String host = "192.18.0.246";
            int port = 10022;
            String privateKey = ".ssh/id_rsa";

            jsch.addIdentity(privateKey);
            System.out.println("identity added ");

            Session session = jsch.getSession(user, host, port);
            System.out.println("session created.");

            // disabling StrictHostKeyChecking may help to make connection but makes it insecure

            session.connect();
            System.out.println("session connected.....");

            Channel channel = session.openChannel("sftp");
            channel.setInputStream(System.in);
            channel.setOutputStream(System.out);
            channel.connect();
            System.out.println("shell channel connected....");

            ChannelSftp c = (ChannelSftp) channel;

            String fileName = "test.txt";
            c.put(fileName, "./in/");
            c.exit();
            System.out.println("done");

        } catch (Exception e) {
            System.err.println(e);
        }
    }
}

Note : This function will ignore the numbers after the decimal mean dot, If you wanna count with decimal then remove the Math.floor(). Direct to the point check this out!

function digitCount ( num )
{
     return Math.floor( num.toString()).length;
}

 digitCount(2343) ;

// ES5+

 const digitCount2 = num => String( Math.floor( Math.abs(num) ) ).length;

 console.log(digitCount2(3343))

Basically What's going on here. toString() and String() same build-in function for converting digit to string, once we converted then we'll find the length of the string by build-in function length.

Alert: But this function wouldn't work properly for negative number, if you're trying to play with negative number then check this answer Or simple put Math.abs() in it;

Cheer You!

Use Eclipse with EPIC: It gives you a nice IDE with debugging possibilities, including the ability to place breakpoints and the Perl Expression View for inspecting the value of variables.

Encoding.ASCII.GetString(buf);

As described by Gideon, this is a known issue.
For use window.onunload = function() { debugger; } instead.
But you can add a breakpoint in Source tab, then can solve your problem. like this:

SQL Server:

SELECT Table_Name, Column_Name 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_CATALOG = 'YOUR_DATABASE'
AND COLUMN_NAME LIKE '%YOUR_COLUMN%'

Oracle:

SELECT owner, table_name, column_name 
FROM all_tab_columns 
WHERE column_name LIKE '%YOUR_COLUMN_NAME%'
AND OWNER IN ('YOUR_SCHEMA_NAME');

• SIMPLE AS THAT!! (SQL, PL/SQL)
  I use it ALL the time to find ALL instances of a column name in a given database (schema).

Yes, it is possible to assign inside if conditional check. But, your variable should have already been declared to assign something.

You can try

iris %>% select(-!!drop.cols)

FYI the available version for raring in Chris Lea's repo is currently 0.8.25

sudo apt-get install nodejs=0.8.25-2chl1~raring1

$(window).scroll(function () {

        var ControlDivTop = $('#cs_controlDivFix');

        $(window).scroll(function () {
            if ($(this).scrollTop() > 50) {
               ControlDivTop.stop().animate({ 'top': ($(this).scrollTop() - 62) + "px" }, 600);
            } else {
              ControlDivTop.stop().animate({ 'top': ($(this).scrollTop()) + "px" },600);
            }
        });
    });

As mentioned by @Tom, the cut and awk approaches actually don't work for CSVs with quoted strings. An alternative is a module for python that provides the command line tool csvfilter. It works like cut, but properly handles CSV column quoting:

csvfilter -f 1,3,5 in.csv > out.csv

If you have python (and you should), you can install it simply like this:

pip install csvfilter

Please take note that the column indexing in csvfilter starts with 0 (unlike awk, which starts with $1). More info at https://github.com/codeinthehole/csvfilter/

With the new Android Architecture of Lifecycle extensions, we can achieve this with utmost ease.

Just ensure you pull this dependency in your build.gradle file:

dependencies {
    implementation "android.arch.lifecycle:extensions:1.1.0"
}

Then in your Application class, use this:

class ArchLifecycleApp : Application(), LifecycleObserver {

    override fun onCreate() {
        super.onCreate()
        ProcessLifecycleOwner.get().lifecycle.addObserver(this)
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_STOP)
    fun onAppBackgrounded() {
        Log.d("MyApp", "App in background")
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_START)
    fun onAppForegrounded() {
        Log.d("MyApp", "App in foreground")
    }
}

In the end, update your AndroidManifest.xml file with:

<application
    android:name=".ArchLifecycleApp"
    //Your extra code
    ....>
</application>

Now, on everytime the Application goes to Foreground or Background, we are going to receive the Logs associated with the two methods declared.

This is an old question, but because this might help a lot of c# coders out there, there is an easy way to solve this right now as follows:

if ((dataTableName?.Rows?.Count ?? 0) > 0)

The following works well in a .php file.

<php? /*your block you want commented out*/ ?>

This seems quick for me :

comm -1 -3 <(sort file1.txt) <(sort file2.txt) > output.txt

If you're using Eclipse Collections (formerly GS Collections), you can use the makeString() method.

List<String> list = Arrays.asList("Bill", "Bob", "Steve");

String string = ListAdapter.adapt(list).makeString(" and ");

Assert.assertEquals("Bill and Bob and Steve", string);

If you can convert your List to an Eclipse Collections type, then you can get rid of the adapter.

MutableList<String> list = Lists.mutable.with("Bill", "Bob", "Steve");
String string = list.makeString(" and ");

If you just want a comma separated string, you can use the version of makeString() that takes no parameters.

Assert.assertEquals(
    "Bill, Bob, Steve", 
    Lists.mutable.with("Bill", "Bob", "Steve").makeString());

Note: I am a committer for Eclipse Collections.

with the intl extension in PHP 5.3+, you can use the NumberFormatter class:

$amount = '12345.67';

$formatter = new NumberFormatter('en_GB',  NumberFormatter::CURRENCY);
echo 'UK: ', $formatter->formatCurrency($amount, 'EUR'), PHP_EOL;

$formatter = new NumberFormatter('de_DE',  NumberFormatter::CURRENCY);
echo 'DE: ', $formatter->formatCurrency($amount, 'EUR'), PHP_EOL;

which prints :

 UK: €12,345.67
 DE: 12.345,67 €

use ResponseEntity<ResponseBean>

Here you can use ResponseBean or Any java bean as you like to return your api response and it is the best practice. I have used Enum for response. it will return status code and status message of API.

@GetMapping(path = "/login")
public ResponseEntity<ServiceStatus> restApiExample(HttpServletRequest request,
            HttpServletResponse response) {
        String username = request.getParameter("username");
        String password = request.getParameter("password");

        loginService.login(username, password, request);
        return new ResponseEntity<ServiceStatus>(ServiceStatus.LOGIN_SUCCESS,
                HttpStatus.ACCEPTED);
    }

for response ServiceStatus or(ResponseBody)

    public enum ServiceStatus {

    LOGIN_SUCCESS(0, "Login success"),

    private final int id;
    private final String message;

    //Enum constructor
    ServiceStatus(int id, String message) {
        this.id = id;
        this.message = message;
    }

    public int getId() {
        return id;
    }

    public String getMessage() {
        return message;
    }
}

Spring REST API should have below key in response

1. Status Code
2. Message

you will get final response below

{

   "StatusCode" : "0",

   "Message":"Login success"

}

you can use ResponseBody(java POJO, ENUM,etc..) as per your requirement.

Simple and easy. You can do this from the URI just like below!

public void getContents(Uri uri)
{
    Cursor vidCursor = getActivity.getContentResolver().query(uri, null, null,
                                                              null, null);
    if (vidCursor.moveToFirst())
    {
        int column_index =
        vidCursor .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        Uri filePathUri = Uri.parse(vidCursor .getString(column_index));
        String video_name =  filePathUri.getLastPathSegment().toString();
        String file_path=filePathUri.getPath();
        Log.i("TAG", video_name + "\b" file_path);
    }
}

This is my version of a bash script. It takes database name as a parameter and converts all tables to another charset and collation (given by another parameters or default value defined in the script).

#!/bin/bash

# mycollate.sh <database> [<charset> <collation>]
# changes MySQL/MariaDB charset and collation for one database - all tables and
# all columns in all tables

DB="$1"
CHARSET="$2"
COLL="$3"

[ -n "$DB" ] || exit 1
[ -n "$CHARSET" ] || CHARSET="utf8mb4"
[ -n "$COLL" ] || COLL="utf8mb4_general_ci"

echo $DB
echo "ALTER DATABASE $DB CHARACTER SET $CHARSET COLLATE $COLL;" | mysql

echo "USE $DB; SHOW TABLES;" | mysql -s | (
    while read TABLE; do
        echo $DB.$TABLE
        echo "ALTER TABLE $TABLE CONVERT TO CHARACTER SET $CHARSET COLLATE $COLL;" | mysql $DB
    done
)

I had this error when accidentally putting the wmain inside a namespace. wmain should not be in any namespace. Moreover, I had a main function in one of the libs I was using, and VS took the main from there, what made it even stranger.

Improving further on ideas of Delan and Andru (which is why this answer is an edited version); console.log is likely to exist whilst the other functions may not, so have the default map to the same function as console.log....

You can write a script which creates console functions if they don't exist:

if (!window.console) console = {};
console.log = console.log || function(){};
console.warn = console.warn || console.log;  // defaults to log
console.error = console.error || console.log; // defaults to log
console.info = console.info || console.log; // defaults to log

Then, use any of the following:

console.log(...);
console.error(...);
console.info(...);
console.warn(...);

These functions will log different types of items (which can be filtered based on log, info, error or warn) and will not cause errors when console is not available. These functions will work in Firebug and Chrome consoles.

I had this error during migration to Ubuntu 17.10, and this solved the problem :

sudo dpkg-reconfigure python3

Maybe you will have to close your session and reconnect.

I don't know if this is happening to you, but sometimes I choose the wrong directory to merge and I get this error even though all the files appear completely fine.

Example:

Merge /svn/Project/branches/some-branch/Sources to /svn/Project/trunk ---> Tree conflict

Merge /svn/Project/branches/some-branch to /svn/Project/trunk ---> OK

This might be a stupid mistake, but it's not always obvious because you think it's something more complicated.

$scope.clearSearch = function () {
    $scope.searchAll = "";
};

http://jsfiddle.net/nzPJD/

JsFiddle of how you could do it without using inline JS.

Named export

In TS you can export with the export keyword. It then can be imported via import {name} from "./mydir";. This is called a named export. A file can export multiple named exports. Also the names of the imports have to match the exports. For example:

// foo.js file
export class foo{}
export class bar{}

// main.js file in same dir
import {foo, bar} from "./foo";

The following alternative syntax is also valid:

// foo.js file
function foo() {};
function bar() {};
export {foo, bar};

// main.js file in same dir
import {foo, bar} from './foo'

Default export

We can also use a default export. There can only be one default export per file. When importing a default export we omit the square brackets in the import statement. We can also choose our own name for our import.

// foo.js file
export default class foo{}

// main.js file in same directory
import abc from "./foo";

It's just JavaScript

Modules and their associated keyword like import, export, and export default are JavaScript constructs, not typescript. However typescript added the exporting and importing of interfaces and type aliases to it.

This works for me: redis-cli KEYS \* | xargs --max-procs=16 -L 100 redis-cli DEL

It list all Keys in redis, then pass using xargs to redis-cli DEL, using max 100 Keys per command, but running 16 command at time, very fast and useful when there is not FLUSHDB or FLUSHALL due to security reasons, for example when using Redis from Bitnami in Docker or Kubernetes. Also, it doesn't require any additional programming language and it just one line.

This is my final code .... (based on previous fixes, thank you big time for headstart, saved a lot of time experimenting). What bugged me was scrolling up, as well as scrolling down ... :)

it always makes me wonder how jquery can be elegant!!!

$(document).ready(function(){

    //run once
    var el=$('#scrolldiv');
    var originalelpos=el.offset().top; // take it where it originally is on the page

    //run on scroll
     $(window).scroll(function(){
        var el = $('#scrolldiv'); // important! (local)
        var elpos = el.offset().top; // take current situation
        var windowpos = $(window).scrollTop();
        var finaldestination = windowpos+originalelpos;
        el.stop().animate({'top':finaldestination},500);
     });

});

To illustrate the problem you are having, let's look at some code...

Dictionary<string, string> test = new Dictionary<string, string>();

test.Add("Key1", "Value1");  // Works fine
test.Add("Key2", "Value2");  // Works fine
test.Add("Key1", "Value3");  // Fails because of duplicate key

The reason that a dictionary has a key/value pair is a feature so you can do this...

var myString = test["Key2"];  // myString is now Value2.

If Dictionary had 2 Key2's, it wouldn't know which one to return, so it limits you to a unique key.

Only you need to add other parameter in your route, the parameter is useAsDefault:true. For example, if you want the DashboardComponent as default you need to do this:

@RouteConfig([
    { path: '/Dashboard', component: DashboardComponent , useAsDefault:true},
    .
    .
    .
    ])

I recomend you to add names to your routes.

{ path: '/Dashboard',name:'Dashboard', component: DashboardComponent , useAsDefault:true}

You can pass variables using this...

$status =1;
 $info = JOBS::where(function($query) use ($status){        
         $query->where('status',$status);
         })->get();
print_r($info);

I created a project like you did. The structure looks like this

Sql Server does not (on my knowledge) have in-build Split function. Split function in general on all platforms would have comma-separated string value to be split into individual strings. In sql server, the main objective or necessary of the Split function is to convert a comma-separated string value (‘abc,cde,fgh’) into a temp table with each string as rows.

The below Split function is Table-valued function which would help us splitting comma-separated (or any other delimiter value) string to individual string.

CREATE FUNCTION dbo.Split(@String varchar(8000), @Delimiter char(1))       
returns @temptable TABLE (items varchar(8000))       
as       
begin       
    declare @idx int       
    declare @slice varchar(8000)       

    select @idx = 1       
        if len(@String)<1 or @String is null  return       

    while @idx!= 0       
    begin       
        set @idx = charindex(@Delimiter,@String)       
        if @idx!=0       
            set @slice = left(@String,@idx - 1)       
        else       
            set @slice = @String       

        if(len(@slice)>0)  
            insert into @temptable(Items) values(@slice)       

        set @String = right(@String,len(@String) - @idx)       
        if len(@String) = 0 break       
    end   
return       
end  

select top 10 * from dbo.split('Chennai,Bangalore,Mumbai',',')

I've found the updated answer from this video, the accepted answer didn't work for me.

First clone the latest repo from git (if haven't) using git clone <HTTPs link of the project> (or using SSH) then go to the desire branch using git checkout <branch name> .

Use the command

git log

to check the latest commits. Copy the shal of the particular commit. Then use the command

git fetch origin <Copy paste the shal here>

After pressing enter key. Now use the command

git checkout FETCH_HEAD

Now the particular commit will be available to your local. Change anything and push the code using git push origin <branch name> . That's all. Check the video for reference.

To switch to the another directory process.chdir("../");

if your port is 3307 (based on your port)

Add this line in xampp\phpMyAdmin\config.inc: after i++

$cfg['Servers'][$i]['port'] = '3307';

Your selector for the .show() and .hide() are not pointing to anything in the code.

Fixed version in jsFiddle

Select first the text you want to format and then press Ctrl+I.

Use Cmd+A first if you wish to format all text in the selected file.

Note: this procedure only re-indents the lines, it does not do any advanced formatting.

In XCode 12 beta:

The new key binding to re-indent is control+I.

The above responses half worked and I'm not why they didn't on my machine but I had to do the following for it work.

1. Created a directory at the root

   /public/js/

2. Paste this into your server.js file with name matching the name of directory created above. Note adding /public as the first param

   app.use('/public',express.static('public'));

3. Finally in the HTML page to which to import the javascript file into,

   <script src="public/js/bundle.js"></script>

It might be easier to read when written out in longhand using the 'simple case' e.g.

CASE DeviceID 
   WHEN '7  ' THEN '01'
   WHEN '10 ' THEN '01'
   WHEN '62 ' THEN '01'
   WHEN '58 ' THEN '01'
   WHEN '60 ' THEN '01'
   WHEN '46 ' THEN '01'
   WHEN '48 ' THEN '01'
   WHEN '50 ' THEN '01'
   WHEN '137' THEN '01'
   WHEN '139' THEN '01'
   WHEN '142' THEN '01'
   WHEN '143' THEN '01'
   WHEN '164' THEN '01'
   WHEN '8  ' THEN '02'
   WHEN '9  ' THEN '02'
   WHEN '63 ' THEN '02'
   WHEN '59 ' THEN '02'
   WHEN '61 ' THEN '02'
   WHEN '47 ' THEN '02'
   WHEN '49 ' THEN '02'
   WHEN '51 ' THEN '02'
   WHEN '138' THEN '02'
   WHEN '140' THEN '02'
   WHEN '141' THEN '02'
   WHEN '144' THEN '02'
   WHEN '165' THEN '02'
   ELSE 'NA' 
END AS clocking

...which kind makes me thing that perhaps you could benefit from a lookup table to which you can JOIN to eliminate the CASE expression entirely.

It is easier with Kotlin using for-in loop:

for (childView in ll.children) {
     //childView is a child of ll         
}

Here ll is id of LinearLayout defined in layout XML.

I use this JSON Helper class in my projects. I found it on the net a year ago but lost the source URL. So I am pasting it directly from my project:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;
/// <summary>
/// JSON Serialization and Deserialization Assistant Class
/// </summary>
public class JsonHelper
{
    /// <summary>
    /// JSON Serialization
    /// </summary>
    public static string JsonSerializer<T> (T t)
    {
        DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
        MemoryStream ms = new MemoryStream();
        ser.WriteObject(ms, t);
        string jsonString = Encoding.UTF8.GetString(ms.ToArray());
        ms.Close();
        return jsonString;
    }
    /// <summary>
    /// JSON Deserialization
    /// </summary>
    public static T JsonDeserialize<T> (string jsonString)
    {
        DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
        MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
        T obj = (T)ser.ReadObject(ms);
        return obj;
    }
}

You can use it like this: Create the classes as Craig W. suggested.

And then deserialize like this

RootObject root = JSONHelper.JsonDeserialize<RootObject>(json);

Google Apps Script will not open automatically web pages, but it could be used to display a message with links, buttons that the user could click on them to open the desired web pages or even to use the Window object and methods like addEventListener() to open URLs.

It's worth to note that UiApp is now deprecated. From Class UiApp - Google Apps Script - Google Developers

Deprecated. The UI service was deprecated on December 11, 2014. To create user interfaces, use the HTML service instead.

The example in the HTML Service linked page is pretty simple,

Code.gs

// Use this code for Google Docs, Forms, or new Sheets.
function onOpen() {
  SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
      .createMenu('Dialog')
      .addItem('Open', 'openDialog')
      .addToUi();
}

function openDialog() {
  var html = HtmlService.createHtmlOutputFromFile('index')
      .setSandboxMode(HtmlService.SandboxMode.IFRAME);
  SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
      .showModalDialog(html, 'Dialog title');
}

syslog() generates a log message, which will be distributed by syslogd.

The file to configure syslogd is /etc/syslog.conf. This file will tell your where the messages are logged.

How to change options in this file ? Here you go http://www.bo.infn.it/alice/alice-doc/mll-doc/duix/admgde/node74.html

This depend on how you want to incorporate it. The scenario 1. click on a link 2. explorer window popped up

<a href="\\server\folder\path" target="_blank">click</a>

If there is a need in a fancy UI - then it will barely serve as a solution.

If you're using FireFox, Fiddler's add-on will automatically configure it to not ignore localhost when capturing traffic. If traffic from localhost is still (or suddenly) not appearing, try disabling and re-enabling traffic capture from Fiddler to goad the add-on into fixing the proxy configuration.

Why don't you use

DbTestDataContext obj = new DbTestDataContext();
var q =from a in obj.GetTable<TableName>() select a;

This is simple.

If anyone is using SQL and they have meta tags there and still the error is shown, this happens because of your connection from .net to SQL.

In you appsettings.json update your connection string to have: Persist Security Info=True. So your connection string should look like this:

"DefaultConnection": "Server=[[server]];Initial Catalog=[[db]];Persist Security Info=True;User ID=[[user]];Password=[[pass]];MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"

I'm doing it this way:

    function f(data,d){
    console.log(d);
    console.log(data);
}
$.ajax({
    url:u,
    success:function(data){ f(data,d);  }
});

var dir = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

I jumped in for the top rated answer and found myself not getting what I expected. I had to read the comments to find what I was looking for.

For that reason I am posting the answer listed in the comments to give it the exposure it deserves.

I've tried everything suggested here but didn't work for me. So in case I can help anyone with a similar issue, every single tutorial I've checked is not updated to work with version 4.

Here is what I've done to make it work

import React from 'react';
import App from './App';

import ReactDOM from 'react-dom';
import {
    HashRouter,
    Route
} from 'react-router-dom';


 ReactDOM.render((
        <HashRouter>
            <div>
                <Route path="/" render={()=><App items={temasArray}/>}/>
            </div>
        </HashRouter >
    ), document.getElementById('root'));

That's the only way I have managed to make it work without any errors or warnings.

In case you want to pass props to your component for me the easiest way is this one:

 <Route path="/" render={()=><App items={temasArray}/>}/>

To answer the question literally (since GitHub is not in the question title), also be aware of this post over on superuser. EDIT: Answer copied here in relevant part, slightly modified for clarity in square brackets:

You're getting rejected because you're trying to delete the branch that your origin has currently "checked out".

If you have direct access to the repo, you can just open up a shell [in the bare repo] directory and use good old git branch to see what branch origin is currently on. To change it to another branch, you have to use git symbolic-ref HEAD refs/heads/another-branch.

This one is much easie.

Threading.Thread.Sleep(3000)

try this

  Calendar c = Calendar.getInstance(); 
  int mseconds = c.get(Calendar.MILLISECOND)

an alternative would be

 Calendar rightNow = Calendar.getInstance();

 long offset = rightNow.get(Calendar.ZONE_OFFSET) +
        rightNow.get(Calendar.DST_OFFSET);
 long sinceMid = (rightNow.getTimeInMils() + offset) %
       (24 * 60 * 60 * 1000);

  System.out.println(sinceMid + " milliseconds since midnight");

It is not possible to use relative paths for AuthUserFile:

File-path is the path to the user file. If it is not absolute (i.e., if it doesn't begin with a slash), it is treated as relative to the ServerRoot.

You have to accept and work around that limitation.

We're using IfDefine together with an apache2 command line parameter:

.htaccess (suitable for both development and live systems):

<IfDefine !development>
  AuthType Basic
  AuthName "Say the secret word"
  AuthUserFile /var/www/hostname/.htpasswd
  Require valid-user
</IfDefine>

Development server configuration (Debian)

Append the following to /etc/apache2/envvars:

export APACHE_ARGUMENTS=-Ddevelopment

Restart your apache afterwards and you'll get a password prompt only when you're not on the development server.

You can of course add another IfDefine for the development server, just copy the block and remove the !.

While Guffa's answer works in many situations, in some cases you may not want the left and/or right pieces of padding to be the parent of the center div. In these cases, you can use a block formatting context on the center and float the padding divs left and right. Here's the code

The HTML:

<div class="container">
    <div class="left"></div>
    <div class="right"></div>
    <div class="center"></div>
</div>

The CSS:

.container {
    width: 100px;
    height: 20px;
}

.left, .right {
    width: 20px;
    height: 100%;
    float: left;
    background: black;   
}

.right {
    float: right;
}

.center {
    overflow: auto;
    height: 100%;
    background: blue;
}

I feel that this element hierarchy is more natural when compared to nested nested divs, and better represents what's on the page. Because of this, borders, padding, and margin can be applied normally to all elements (ie: this 'naturality' goes beyond style and has ramifications).

Note that this only works on divs and other elements that share its 'fill 100% of the width by default' property. Inputs, tables, and possibly others will require you to wrap them in a container div and add a little more css to restore this quality. If you're unlucky enough to be in that situation, contact me and I'll dig up the css.

First I would recommend to use ProcessBuilder ( since 1.5 )
Simple usage is described here

I've encountered problem when launching Python script from Java, script was producing too much output to standard out and everything went bad.

var module = angular.module("example", []);

module.controller("orderByController", function ($scope) {
    $scope.orderByValue = function (value) {
        return value;
    };

    $scope.items = ["c", "b", "a"];
    $scope.objList = [
        {
            "name": "c"
        }, {
            "name": "b"
        }, {
            "name": "a"
        }];
        $scope.item = "b";
    });

Comparator is a functional interface, and Integer::max complies with that interface (after autoboxing/unboxing is taken into consideration). It takes two int values and returns an int - just as you'd expect a Comparator<Integer> to (again, squinting to ignore the Integer/int difference).

However, I wouldn't expect it to do the right thing, given that Integer.max doesn't comply with the semantics of Comparator.compare. And indeed it doesn't really work in general. For example, make one small change:

for (int i = 1; i <= 20; i++)
    list.add(-i);

... and now the max value is -20 and the min value is -1.

Instead, both calls should use Integer::compare:

System.out.println(list.stream().max(Integer::compare).get());
System.out.println(list.stream().min(Integer::compare).get());

If you want to manage key misses you should use TryGetValue

https://msdn.microsoft.com/en-gb/library/bb347013(v=vs.110).aspx

string value = "";
if (openWith.TryGetValue("tif", out value))
{
    Console.WriteLine("For key = \"tif\", value = {0}.", value);
}
else
{
    Console.WriteLine("Key = \"tif\" is not found.");
}

String s = "3.14";
float f = Float.parseFloat(s);

If you are planning to hide show some span based on click event which is initially hidden with style="display:none" then .toggle() is best option to go with.

$("span").toggle();

Reasons : Each time you don't need to check whether the style is already there or not. .toggle() will take care of that automatically and hide/show span based on current state.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="button" value="Toggle" onclick="$('#hiddenSpan').toggle();"/>_x000D_
<br/>_x000D_
<br/>_x000D_
<span id="hiddenSpan" style="display:none">Just toggle me</span>

A simple trick to change a particular point marker shape, size... is to first plot it with all the other data then plot one more plot only with that point (or set of points if you want to change the style of multiple points). Suppose we want to change the marker shape of second point:

x = [1,2,3,4,5]
y = [2,1,3,6,7]

plt.plot(x, y, "-o")
x0 = [2]
y0 = [1]
plt.plot(x0, y0, "s")

plt.show()

Result is: Plot with multiple markers

You can also set processData to true:

collection.fetch({ 
    data: { page: 1 },
    processData: true
});

Jquery will auto process data object into param string,

but in Backbone.sync function, Backbone turn the processData off because Backbone will use other method to process data in POST,UPDATE...

in Backbone source:

if (params.type !== 'GET' && !Backbone.emulateJSON) {
    params.processData = false;
}

There's a change_column method, just execute it in your migration with datetime as a new type.

change_column(:my_table, :my_column, :my_new_type)

I regularly "jsonify" np.arrays. Try using the ".tolist()" method on the arrays first, like this:

import numpy as np
import codecs, json 

a = np.arange(10).reshape(2,5) # a 2 by 5 array
b = a.tolist() # nested lists with same data, indices
file_path = "/path.json" ## your path variable
json.dump(b, codecs.open(file_path, 'w', encoding='utf-8'), separators=(',', ':'), sort_keys=True, indent=4) ### this saves the array in .json format

In order to "unjsonify" the array use:

obj_text = codecs.open(file_path, 'r', encoding='utf-8').read()
b_new = json.loads(obj_text)
a_new = np.array(b_new)

Unicode string handling is already standardized in Python 3.

1. char's are already stored in Unicode (32-bit) in memory

2. You only need to open file in utf-8
   (32-bit Unicode to variable-byte-length utf-8 conversion is automatically performed from memory to file.)

   out1 = "(???? ??? ??´ ??` ???` )"
   fobj = open("t1.txt", "w", encoding="utf-8")
   fobj.write(out1)
   fobj.close()
   

<meta http-equiv="X-UA-Compatible" content="IE=8" /> 

should force your page to render in IE8 standards. The user may add the site to compatibility list but this tag will take precedence.

A quick way to check would be to load the page and type the following the address bar :

javascript:alert(navigator.userAgent) 

If you see IE7 in the string, it is loading in compatibility mode, otherwise not.

In many cases what you need is just

[self tintColor] 
// or if in a ViewController
[self.view tintColor]

or for swift

self.tintColor
// or if in a ViewController
self.view.tintColor

If you upgrade a package, the old one will be uninstalled.

A convenient way to do this is to use this pip-upgrader which also updates the versions in your requirements.txt file for the chosen packages (or all packages).

Installation

pip install pip-upgrader

Usage

Activate your virtualenv (important, because it will also install the new versions of upgraded packages in current virtualenv).

cd into your project directory, and then run:

pip-upgrade

Advanced usage

If the requirements are placed in a non-standard location, send them as arguments:

pip-upgrade path/to/requirements.txt

If you already know what package you want to upgrade, simply send them as arguments:

pip-upgrade -p django -p celery -p dateutil

If you need to upgrade to pre-release / post-release version, add --prerelease argument to your command.

Full disclosure: I wrote this package.

Open it in a hex editor and make sure that the first three bytes are a UTF8 BOM (EF BB BF)

Just type in the following command: taskkill /f /im (program name) To find out the im of your program open task manager and look at the process while your program is running. After the program has run a process will disappear from the task manager; that is your program.

String#toLowerCase and String#toUpperCase are the methods you need.

I found that switching to use full html instead of filtered html (below the editor in the Text Format dropdown box) is what fixed this problem for me. Otherwise the style would disappear.

If you want to send a text to specific device when multiple devices connected. First look for the attached devices using adb devices

adb devices
List of devices attached
3004e25a57192200        device
31002d9e592b7300        device

then get your specific device id and try the following

adb -s 31002d9e592b7300 shell input text 'your text'

A Simple and an easy way

}

I found this little neat program for Windows called clumsy. It's in kind of alpha status, but it seem to work fine for me, and it's open source.

Edit: Others have noticed that you can't limit bandwidth with clumsy, and that's true. You can only add Latency and a couple of other network related errors. This will disqualify this answer as a valid answer to the question, however since I had good use for it when I wanted to simulate a bad network so I'll leave it here as long as it has > 0 votes or similar.

The password_hash() function in PHP is an inbuilt function , used to create a new password hash with different algorithms and options. the function uses a strong hashing algorithm.

the function take 2 mandetory parametres ($password and $algorithm,) and 1 optional parameter ($options).

$strongPassword = password_hash( $password, $algorithm, $options )

Algoristrong textthms allowed right now for password_hash() are :

• PASSWORD_DEFAULT

• PASSWORD_BCRYPT

• ASSWORD_ARGON2I

• PASSWORD_ARGON2ID

example : echo password_hash("abcDEF", PASSWORD_DEFAULT);

answer : $2y$10$KwKceUaG84WInAif5ehdZOkE4kHPWTLp0ZK5a5OU2EbtdwQ9YIcGy

answer :$2y$10$SNly5bFzB/R6OVbBMq1bj.yiOZdsk6Mwgqi4BLR2sqdCvMyv/AyL2

to use the BCRYPT as password, use option cost =12 in an array , also change 1st parameter $password to some strong password like "wgt167yuWBGY@#1987__"

Example: echo password_hash("wgt167yuWBGY@#1987__", PASSWORD_BCRYPT ,['cost' => 12]);

Answer : $2y$12$TjSggXiFSidD63E.QP8PJOds2texJfsk/82VaNU8XRZ/niZhzkJ6S

My favourite way of doing this is "splitting and popping":

var str = "test_23";
alert(str.split("_").pop());
// -> 23

var str2 = "adifferenttest_153";
alert(str2.split("_").pop());
// -> 153

split() splits a string into an array of strings using a specified separator string.
pop() removes the last element from an array and returns that element.

Are you sure it's compiling as C++? Check your file name (it should end in .cpp). Check your project settings.

There's simply nothing wrong with your program, and cout is in namespace std. Your installation of VS 2010 Beta 2 is defective, and I don't think it's just your installation.

I don't think VS 2010 is ready for C++ yet. The standard "Hello, World" program didn't work on Beta 1. I just tried creating a test Win32 console application, and the generated test.cpp file didn't have a main() function.

I've got a really, really bad feeling about VS 2010.

In the context definition, define only two DbSet contexts per context class.

Run "apt install bash" It will install everything you need and the command will work

You have a certificate which is self-signed, so it's non-trusted by default, that's why OpenSSL complains. This warning is actually a good thing, because this scenario might also rise due to a man-in-the-middle attack.

To solve this, you'll need to install it as a trusted server. If it's signed by a non-trusted CA, you'll have to install that CA's certificate as well.

Have a look at this link about installing self-signed certificates.

When hosting your application on another service (like Heroku, Nodejitsu, and AWS), your host may independently configure the process.env.PORT variable for you; after all, your script runs in their environment.

Amazon's Elastic Beanstalk does this. If you try to set a static port value like 3000 instead of process.env.PORT || 3000 where 3000 is your static setting, then your application will result in a 500 gateway error because Amazon is configuring the port for you.

This is a minimal Express application that will deploy on Amazon's Elastic Beanstalk:

var express = require('express');
var app = express();

app.get('/', function (req, res) {
  res.send('Hello World!');
});

// use port 3000 unless there exists a preconfigured port
var port = process.env.PORT || 3000;

app.listen(port);

The best way in my eyes is to use the concat() method provided by the String class itself.

The useage would, in your case, look like this:

String myConcatedString = cursor.getString(numcol).concat('-').
       concat(cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE)));

If you are using SQL Server 2012 or above versions,

Use Format() function.

There are already multiple answers and formatting types for SQL server. But most of the methods are somewhat ambiguous and it would be difficult for you to remember the numbers for format type or functions with respect to Specific Date Format. That's why in next versions of SQL server there is better option.

FORMAT ( value, format [, culture ] )

Culture option is very useful, as you can specify date as per your viewers.

You have to remember d (for small patterns) and D (for long patterns).

1."d" - Short date pattern.

2009-06-15T13:45:30 -> 6/15/2009 (en-US)
2009-06-15T13:45:30 -> 15/06/2009 (fr-FR)
2009-06-15T13:45:30 -> 2009/06/15 (ja-JP)

If you want more formats, you can go to:

1. Standard Date and Time Format Strings
2. Custom Date and Time Format Strings

Well, the most likely difference is that you still have to do an actual lookup of localhost somewhere.

If you use 127.0.0.1, then (intelligent) software will just turn that directly into an IP address and use it. Some implementations of gethostbyname will detect the dotted format (and presumably the equivalent IPv6 format) and not do a lookup at all.

Otherwise, the name has to be resolved. And there's no guarantee that your hosts file will actually be used for that resolution (first, or at all) so localhost may become a totally different IP address.

By that I mean that, on some systems, a local hosts file can be bypassed. The host.conf file controls this on Linux (and many other Unices).

You Can Used This :

function ViewImage(){
 function getBase64(file) {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.readAsDataURL(file);
    reader.onload = () => resolve(reader.result);
    reader.onerror = error => reject(error);
  });
}
var file = document.querySelector('input[type="file"]').files[0];
getBase64(file).then(data =>$("#ImageBase46").val(data));
}

Add To Your Input onchange=ViewImage();

Use grep and regular expressions, for example if you want 4 minutes interval of logs:

grep "31/Mar/2002:19:3[1-5]" logfile

will return all logs lines between 19:31 and 19:35 on 31/Mar/2002. Supposing you need the last 5 days starting from today 27/Sep/2011 you may use the following:

grep "2[3-7]/Sep/2011" logfile

Although this is an old thread, here are two examples for solving the problem in Java8.

sorting by the first column ([][0]):

double[][] myArr = new double[mySize][2];
// ...
java.util.Arrays.sort(myArr, java.util.Comparator.comparingDouble(a -> a[0]));

sorting by the first two columns ([][0], [][1]):

double[][] myArr = new double[mySize][2];
// ...
java.util.Arrays.sort(myArr, java.util.Comparator.<double[]>comparingDouble(a -> a[0]).thenComparingDouble(a -> a[1]));

After reading your question, I would say, generate special token to do request required. This token will live in specific time (lets say in one day).

Here is an example from to generate authentication token:

(day * 10) + (month * 100) + (year (last 2 digits) * 1000)

for example: 3 June 2011

(3 * 10) + (6 * 100) + (11 * 1000) = 
30 + 600 + 11000 = 11630

then concatenate with user password, example "my4wesomeP4ssword!"

11630my4wesomeP4ssword!

Then do MD5 of that string:

05a9d022d621b64096160683f3afe804

When do you call a request, always use this token,

https://mywebservice.com/?token=05a9d022d621b64096160683f3afe804&op=getdata

This token is always unique everyday, so I guess this kind of protection is more than sufficient to always protect ur service.

Hope helps

As already stated in earlier answers, ng-pristine is for indicating that the field has not been modified, whereas ng-dirty is for telling it has been modified. Why need both?

Let's say we've got a form with phone and e-mail address among the fields. Either phone or e-mail is required, and you also have to notify the user when they've got invalid data in each field. This can be accomplished by using ng-dirty and ng-pristine together:

<form name="myForm">
    <input name="email" ng-model="data.email" ng-required="!data.phone">
    <div class="error" 
         ng-show="myForm.email.$invalid && 
                  myForm.email.$pristine &&
                  myForm.phone.$pristine">Phone or e-mail required</div>
    <div class="error" 
         ng-show="myForm.email.$invalid && myForm.email.$dirty">
        E-mail is invalid
    </div>

    <input name="phone" ng-model="data.phone" ng-required="!data.email">
    <div class="error" 
         ng-show="myForm.phone.$invalid && 
                  myForm.email.$pristine &&
                  myForm.phone.$pristine">Phone or e-mail required</div>
    <div class="error" 
         ng-show="myForm.phone.$invalid && myForm.phone.$dirty">
        Phone is invalid
    </div>
</form>

armhf stands for "arm hard float", and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support.

On the beaglebone black, for example:

:~$ dpkg --print-architecture
armhf

Although other commands (such as uname -a or arch) will just show armv7l

:~$ cat /proc/cpuinfo 
processor       : 0
model name      : ARMv7 Processor rev 2 (v7l)
BogoMIPS        : 995.32
Features        : half thumb fastmult vfp edsp thumbee neon vfpv3 tls
...

The vfpv3 listed under Features is what refers to the floating point support.

Incidentally, armhf, if your processor supports it, basically supersedes Raspbian, which if I understand correctly was mainly a rebuild of armhf with work arounds to deal with the lack of floating point support on the original raspberry pi's. Nowdays, of course, there's a whole ecosystem build up around Raspbian, so they're probably not going to abandon it. However, this is partly why the beaglebone runs straight debian, and that's ok even if you're used to Raspbian, unless you want some of the special included non-free software such as Mathematica.

If you write a function then once you leave it all names inside disappear.

The concept is called namespace and it's so good, it made it into the Zen of Python:

Namespaces are one honking great idea -- let's do more of those!

The namespace of IPython can likewise be reset with the magic command %reset -f. (The -f means "force"; in other words, "don't ask me if I really want to delete all the variables, just do it.")

Yes you can. In c++, class and struct are kind of similar. We can define not only structure inside a class, but also a class inside one. It is called inner class.

As an example I am adding a simple Trie class.

class Trie {
private:
    struct node{
        node* alp[26];
        bool isend;
    };
    node* root;
    node* createNode(){
        node* newnode=new node();
        for(int i=0; i<26; i++){
            newnode->alp[i]=nullptr;
        }
        newnode->isend=false;
        return newnode;
    }
public:
    /** Initialize your data structure here. */
    Trie() {
        root=createNode();
    }

    /** Inserts a word into the trie. */
    void insert(string word) {
        node* head=root;
        for(int i=0; i<word.length(); i++){
            if(head->alp[int(word[i]-'a')]==nullptr){
                node* newnode=createNode();
                head->alp[int(word[i]-'a')]=newnode;
            }
            head=head->alp[int(word[i]-'a')];
        }
        head->isend=true;
    }

    /** Returns if the word is in the trie. */
    bool search(string word) {
        node* head=root;
        for(int i=0; i<word.length(); i++){
            if(head->alp[int(word[i]-'a')]==nullptr){
                return false;
            }
            head=head->alp[int(word[i]-'a')];
        }
        if(head->isend){return true;}
        return false;
    }

    /** Returns if there is any word in the trie that starts with the given prefix. */
    bool startsWith(string prefix) {
        node* head=root;
        for(int i=0; i<prefix.length(); i++){
            if(head->alp[int(prefix[i]-'a')]==nullptr){
                return false;
            }
            head=head->alp[int(prefix[i]-'a')];
        }
        return true;
    }
};

/**
 * Your Trie object will be instantiated and called as such:
 * Trie* obj = new Trie();
 * obj->insert(word);
 * bool param_2 = obj->search(word);
 * bool param_3 = obj->startsWith(prefix);
 */

And it's maybe also handy to know that BigTable is not a relational database (like MySQL) but a huge (distributed) hash table which has very different characteristics. You can play around with (a limited version) of BigTable yourself on the Google AppEngine platform.

Next to Hadoop mentioned above there are many other implementations that try to solve the same problems as BigTable (scalability, availability). I saw a nice blog post yesterday listing most of them here.

If you want to compare with a particular date , You can directly write it like :

select * from `table_name` where timestamp >= '2018-07-07';

// here the timestamp is the name of the column having type as timestamp

or

For fetching today date , CURDATE() function is available , so :

select * from `table_name` where timestamp >=  CURDATE();

My home-grown regular expression replace function can be used for this.

Demo

See this DB-Fiddle demo, which returns the second word ("I") from a famous sonnet and the number of occurrences of it (1).

SQL

Assuming MySQL 8 or later is being used (to allow use of a Common Table Expression), the following will return the second word and the number of occurrences of it:

WITH cte AS (
     SELECT digits.idx,
            SUBSTRING_INDEX(SUBSTRING_INDEX(words, '~', digits.idx + 1), '~', -1) word
     FROM
     (SELECT reg_replace(UPPER(txt),
                         '[^''’a-zA-Z-]+',
                         '~',
                         TRUE,
                         1,
                         0) AS words
      FROM tbl) delimited
     INNER JOIN
     (SELECT @row := @row + 1 as idx FROM 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t1,
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t2, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t3, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t4, 
      (SELECT @row := -1) t5) digits
     ON LENGTH(REPLACE(words, '~' , '')) <= LENGTH(words) - digits.idx)
SELECT c.word,
       subq.occurrences
FROM cte c
LEFT JOIN (
  SELECT word,
         COUNT(*) AS occurrences
  FROM cte
  GROUP BY word
) subq
ON c.word = subq.word
WHERE idx = 1; /* idx is zero-based so 1 here gets the second word */

Explanation

A few tricks are used in the SQL above and some accreditation is needed. Firstly the regular expression replacer is used to replace all continuous blocks of non-word characters - each being replaced by a single tilda (~) character. Note: A different character could be chosen instead if there is any possibility of a tilda appearing in the text.

The technique from this answer is then used for transforming a string with delimited values into separate row values. It's combined with the clever technique from this answer for generating a table consisting of a sequence of incrementing numbers: 0 - 10,000 in this case.

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

This will need new var ttfixed

Then this under the tt value slot and replace all pointers down below that are tt to ttfixed

ttfixed = (tt.replace(",", "."));

Experts will tell you: "When I see the UI, I will know whether to use an Activity or a Fragment". In the beginning this will not have any sense, but in time, you will actually be able to tell if you need Fragment or not.

There is a good practice I found very helpful for me. It occurred to me while I was trying to explain something to my daughter.

Namely, imagine a box which represents a screen. Can you load another screen in this box? If you use a new box, will you have to copy multiple items from the 1st box? If the answer is Yes, then you should use Fragments, because the root Activity can hold all duplicated elements to save you time in creating them, and you can simply replace parts of the box.

But don't forget that you always need a box container (Activity) or your parts will be dispersed. So one box with parts inside.

Take care not to misuse the box. Android UX experts advise (you can find them on YouTube) when we should explicitly load another Activity, instead to use a Fragment (like when we deal with the Navigation Drawer which has categories). Once you feel comfortable with Fragments, you can watch all their videos. Even more they are mandatory material.

Can you right now look at your UI and figure out if you need an Activity or a Fragment? Did you get a new perspective? I think you did.

just go to BUILD->Build APK and it's done

The first 2 examples act very differently if you are REPLACING them by something. If you match on this:

str = str.replace(/^(7|8|9)/ig,''); 

you would replace 7 or 8 or 9 by the empty string.

If you match on this

str = str.replace(/^[7|8|9]/ig,''); 

you will replace 7 or 8 or 9 OR THE VERTICAL BAR!!!! by the empty string.

I just found this out the hard way.

Personally, I got around this in a slightly different way - I had a pivot table querying an SQL server source and I was using the timeline slicer to restrict the results to a date range - I then wanted to summarise the pivot results in another table.

I selected the 'source' pivot table and created a named range called 'SourcePivotData'.

Create your summary pivot tables using the named range as a source.

In the worksheet events for the source pivot table, I put the following code:

Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)

'Update the address of the named range
ThisWorkbook.Names("SourcePivotData").RefersTo = "='" & Target.TableRange1.Worksheet.Name & "'!" & Target.TableRange1.AddressLocal

'Refresh any pivot tables that use this as a source
Dim pt As PivotTable
Application.DisplayAlerts = False
For Each pt In Sheet2.PivotTables
    pt.PivotCache.Refresh
Next pt
Application.DisplayAlerts = True

End Sub

Works nicely for me! :)

The general idea is to sweep the function across. You have many options, one is apply():

R> set.seed(42)
R> M <- matrix(rnorm(40),ncol=4)
R> apply(M, 2, sd)
[1] 0.835449 1.630584 1.156058 1.115269
R> 

You need to add annotations to the Junit class, telling it to use the SpringJunitRunner. The ones you want are:

@ContextConfiguration("/test-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)

This tells Junit to use the test-context.xml file in same directory as your test. This file should be similar to the real context.xml you're using for spring, but pointing to test resources, naturally.

None of these solutions worked for me. I needed to know the server port while constructing a Swagger configuration bean. Using ServerProperties worked for me:

import javax.annotation.PostConstruct;
import javax.inject.Inject;
import javax.ws.rs.ApplicationPath;

import io.swagger.jaxrs.config.BeanConfig;
import io.swagger.jaxrs.listing.ApiListingResource;
import io.swagger.jaxrs.listing.SwaggerSerializers;

import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.stereotype.Component;

@Component
@ApplicationPath("api")
public class JerseyConfig extends ResourceConfig 
{
    @Inject
    private org.springframework.boot.autoconfigure.web.ServerProperties serverProperties;

    public JerseyConfig() 
    {
        property(org.glassfish.jersey.server.ServerProperties.BV_SEND_ERROR_IN_RESPONSE, true);
    }

    @PostConstruct
    protected void postConstruct()
    {
        // register application endpoints
        registerAndConfigureSwaggerUi();
    }

    private void registerAndConfigureSwaggerUi()
    {
        register(ApiListingResource.class);
        register(SwaggerSerializers.class);

        final BeanConfig config = new BeanConfig();
        // set other properties
        config.setHost("localhost:" + serverProperties.getPort()); // gets server.port from application.properties file         
    }
}

This example uses Spring Boot auto configuration and JAX-RS (not Spring MVC).

(Editor's Note: This answer was correct in May 2013 for Android Studio v0.1, but is no longer accurate as of July 2014, since the mentioned menu option does not exist anymore -- see this answer for up-to-date alternative).

First you will have to mark it as excluded. Then on right click you will be able to delete the project.

You just need to create a function which contains adjustment of scrolling of your screen

for example

window.scroll(0,0) OR window.scrollTo() by passing appropriate parameter.

window.scrollTo(xpos, ypos) --> expected parameter.

The listed return type of the method is Task<string>. You're trying to return a string. They are not the same, nor is there an implicit conversion from string to Task<string>, hence the error.

You're likely confusing this with an async method in which the return value is automatically wrapped in a Task by the compiler. Currently that method is not an async method. You almost certainly meant to do this:

private async Task<string> methodAsync() 
{
    await Task.Delay(10000);
    return "Hello";
}

There are two key changes. First, the method is marked as async, which means the return type is wrapped in a Task, making the method compile. Next, we don't want to do a blocking wait. As a general rule, when using the await model always avoid blocking waits when you can. Task.Delay is a task that will be completed after the specified number of milliseconds. By await-ing that task we are effectively performing a non-blocking wait for that time (in actuality the remainder of the method is a continuation of that task).

If you prefer a 4.0 way of doing it, without using await , you can do this:

private Task<string> methodAsync() 
{
    return Task.Delay(10000)
        .ContinueWith(t => "Hello");
}

The first version will compile down to something that is more or less like this, but it will have some extra boilerplate code in their for supporting error handling and other functionality of await we aren't leveraging here.

If your Thread.Sleep(10000) is really meant to just be a placeholder for some long running method, as opposed to just a way of waiting for a while, then you'll need to ensure that the work is done in another thread, instead of the current context. The easiest way of doing that is through Task.Run:

private Task<string> methodAsync() 
{
    return Task.Run(()=>
        {
            SomeLongRunningMethod();
            return "Hello";
        });
}

Or more likely:

private Task<string> methodAsync() 
{
    return Task.Run(()=>
        {
            return SomeLongRunningMethodThatReturnsAString();
        });
}

If you're experimenting with Metal rendering & you're extracting the CGImage generated by imageByApplyingAlpha in the first reply, you may end up with a Metal rendering that's larger than you expect. While experimenting with Metal, you may want to change one line of code in imageByApplyingAlpha:

    UIGraphicsBeginImageContextWithOptions (self.size, NO, 1.0f);
//  UIGraphicsBeginImageContextWithOptions (self.size, NO, 0.0f);

If you're using a device with a scale factor of 3.0, like the iPhone 11 Pro Max, the 0.0 scale factor shown above will give you an CGImage that's three times larger than you're expecting. Changing the scale factor to 1.0 should avoid any scaling.

Hopefully, this reply will save beginners a lot of aggravation.

You increment it past the end of the (empty) container in the for loop's loop expression.

            divisor, word1, word2 = m
        elif num < t[0]:
            divisor, word1, word2 = b
        else:
            divisor, word1, word2 = t
        div_, mod_ = divmod(num, divisor)
        if mod_ == 0:
            return '{} {}'.format(int2words(div_), word1)
        else:
            return '{} {} {}'.format(int2words(div_), word2, int2words(mod_))

You open the file in text mode.

More specifically:

ifile  = open('sample.csv', "rt", encoding=<theencodingofthefile>)

Good guesses for encoding is "ascii" and "utf8". You can also leave the encoding off, and it will use the system default encoding, which tends to be UTF8, but may be something else.

In simple English from GROUP BY with two parameters what we are doing is looking for similar value pairs and get the count to a 3rd column.

Look at the following example for reference. Here I'm using International football results from 1872 to 2020

Explanation: The meaning of the first row is there were 11 Friendly tournaments held on Southern Rhodesia in total.

Note: Here it's mandatory to use a counter column in this case.

From the fine manual:

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

There's no need to specify the type when you're just changing the nullability.

Here are two functions that may help if your backup is corrupted, or you have a few partially corrupted backups as well (this may happen if you backup the corrupted objects).

Run both in the repo you're trying to recover.

Standard warning: only use if you're really desperate and you have backed up your (corrupted) repo. This might not resolve anything, but at least should highlight the level of corruption.

fsck_rm_corrupted() {
    corrupted='a'
    while [ "$corrupted" ]; do
        corrupted=$(                                  \
        git fsck --full --no-dangling 2>&1 >/dev/null \
            | grep 'stored in'                          \
            | sed -r 's:.*(\.git/.*)\).*:\1:'           \
        )
        echo "$corrupted"
        rm -f "$corrupted"
    done
}

if [ -z "$1" ]  || [ ! -d "$1" ]; then
    echo "'$1' is not a directory. Please provide the directory of the git repo"
    exit 1
fi

pushd "$1" >/dev/null
fsck_rm_corrupted
popd >/dev/null

and

unpack_rm_corrupted() {
    corrupted='a'
    while [ "$corrupted" ]; do
        corrupted=$(                                  \
        git unpack-objects -r < "$1" 2>&1 >/dev/null \

        )
        echo "$corrupted"

    done
}

This approach requires a reference to System.Windows.Forms.

it would be helpful to know if you use linux or windows. in linux the settings are located in ~/.smartgit/3. You could try to remove this folder. Imho this is also worth a try in Windows.

if it helps someone else, I had an activity with 2 layouts that I toggled on and off for visibilty, trying to emulate a kind of page1 > page2 structure. if they were on page 2 and pressed the back button I wanted them to go back to page 1, if they pressed the back button on page 1 it should still work as normal. Its pretty basic but it works

@Override
public void onBackPressed() {
// check if page 2 is open
    RelativeLayout page2layout = (RelativeLayout)findViewById(R.id.page2layout);
    if(page2layout.getVisibility() == View.VISIBLE){
        togglePageLayout(); // my method to toggle the views
        return;
    }else{
        super.onBackPressed(); // allows standard use of backbutton for page 1
    }

}

hope it helps someone, cheers

JavaScript is single threaded and has a synchronous execution model. Single threaded means that one command is being executed at a time. Synchronous means one at a time i.e. one line of code is being executed at time in order the code appears. So in JavaScript one thing is happening at a time.

Execution Context

The JavaScript engine interacts with other engines in the browser. In the JavaScript execution stack there is global context at the bottom and then when we invoke functions the JavaScript engine creates new execution contexts for respective functions. When the called function exits its execution context is popped from the stack, and then next execution context is popped and so on...

For example

function abc()
{
   console.log('abc');
}


function xyz()
{
   abc()
   console.log('xyz');
}
var one = 1;
xyz();

In the above code a global execution context will be created and in this context var one will be stored and its value will be 1... when the xyz() invocation is called then a new execution context will be created and if we had defined any variable in xyz function those variables would be stored in the execution context of xyz(). In the xyz function we invoke abc() and then the abc() execution context is created and put on the execution stack... Now when abc() finishes its context is popped from stack, then the xyz() context is popped from stack and then global context will be popped...

Now about asynchronous callbacks; asynchronous means more than one at a time.

Just like the execution stack there is the Event Queue. When we want to be notified about some event in the JavaScript engine we can listen to that event, and that event is placed on the queue. For example an Ajax request event, or HTTP request event.

Whenever the execution stack is empty, like shown in above code example, the JavaScript engine periodically looks at the event queue and sees if there is any event to be notified about. For example in the queue there were two events, an ajax request and a HTTP request. It also looks to see if there is a function which needs to be run on that event trigger... So the JavaScript engine is notified about the event and knows the respective function to execute on that event... So the JavaScript engine invokes the handler function, in the example case, e.g. AjaxHandler() will be invoked and like always when a function is invoked its execution context is placed on the execution context and now the function execution finishes and the event ajax request is also removed from the event queue... When AjaxHandler() finishes the execution stack is empty so the engine again looks at the event queue and runs the event handler function of HTTP request which was next in queue. It is important to remember that the event queue is processed only when execution stack is empty.

For example see the code below explaining the execution stack and event queue handling by Javascript engine.

function waitfunction() {
    var a = 5000 + new Date().getTime();
    while (new Date() < a){}
    console.log('waitfunction() context will be popped after this line');
}

function clickHandler() {
    console.log('click event handler...');   
}

document.addEventListener('click', clickHandler);


waitfunction(); //a new context for this function is created and placed on the execution stack
console.log('global context will be popped after this line');

And

<html>
    <head>

    </head>
    <body>

        <script src="program.js"></script>
    </body>
</html>

Now run the webpage and click on the page, and see the output on console. The output will be

waitfunction() context will be popped after this line
global context will be emptied after this line
click event handler...

The JavaScript engine is running the code synchronously as explained in the execution context portion, the browser is asynchronously putting things in event queue. So the functions which take a very long time to complete can interrupt event handling. Things happening in a browser like events are handled this way by JavaScript, if there is a listener supposed to run, the engine will run it when the execution stack is empty. And events are processed in the order they happen, so the asynchronous part is about what is happening outside the engine i.e. what should the engine do when those outside events happen.

So JavaScript is always synchronous.

Both answers are in the ballpark but neither is a complete answer.

MyClass.class.isInstance(obj) is for checking an instance. It returns true when the parameter obj is non-null and can be cast to MyClass without raising a ClassCastException. In other words, obj is an instance of MyClass or its subclasses.

MyClass.class.isAssignableFrom(Other.class) will return true if MyClass is the same as, or a superclass or superinterface of, Other. Other can be a class or an interface. It answers true if Other can be converted to a MyClass.

A little code to demonstrate:

public class NewMain
{
    public static void main(String[] args)
    {
        NewMain nm = new NewMain();
        nm.doit();
    }

    class A { }

    class B extends A { }

    public void doit()
    {
        A myA = new A();
        B myB = new B();
        A[] aArr = new A[0];
        B[] bArr = new B[0];

        System.out.println("b instanceof a: " + (myB instanceof A)); // true
        System.out.println("b isInstance a: " + A.class.isInstance(myB)); //true
        System.out.println("a isInstance b: " + B.class.isInstance(myA)); //false
        System.out.println("b isAssignableFrom a: " + A.class.isAssignableFrom(B.class)); //true
        System.out.println("a isAssignableFrom b: " + B.class.isAssignableFrom(A.class)); //false
        System.out.println("bArr isInstance A: " + A.class.isInstance(bArr)); //false
        System.out.println("bArr isInstance aArr: " + aArr.getClass().isInstance(bArr)); //true
        System.out.println("bArr isAssignableFrom aArr: " + aArr.getClass().isAssignableFrom(bArr.getClass())); //true
    }

Ok so here's how I figured this out. It all has to do with CORS policy. Before the POST request, Chrome was doing a preflight OPTIONS request, which should be handled and acknowledged by the server prior to the actual request. Now this is really not what I wanted for such a simple server. Hence, resetting the headers client side prevents the preflight:

app.config(function ($httpProvider) {
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
});

The browser will now send a POST directly. Hope this helps a lot of folks out there... My real problem was not understanding CORS enough.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

Like the other answers said, sp_reset_connection indicates that connection pool is being reused. Be aware of one particular consequence!

Jimmy Mays' MSDN Blog said:

sp_reset_connection does NOT reset the transaction isolation level to the server default from the previous connection's setting.

UPDATE: Starting with SQL 2014, for client drivers with TDS version 7.3 or higher, the transaction isolation levels will be reset back to the default.

ref: SQL Server: Isolation level leaks across pooled connections

Here is some additional information:

What does sp_reset_connection do?

Data access API's layers like ODBC, OLE-DB and System.Data.SqlClient all call the (internal) stored procedure sp_reset_connection when re-using a connection from a connection pool. It does this to reset the state of the connection before it gets re-used, however nowhere is documented what things get reset. This article tries to document the parts of the connection that get reset.

sp_reset_connection resets the following aspects of a connection:

• All error states and numbers (like @@error)

• Stops all EC's (execution contexts) that are child threads of a parent EC executing a parallel query

• Waits for any outstanding I/O operations that is outstanding

• Frees any held buffers on the server by the connection

• Unlocks any buffer resources that are used by the connection

• Releases all allocated memory owned by the connection

• Clears any work or temporary tables that are created by the connection

• Kills all global cursors owned by the connection

• Closes any open SQL-XML handles that are open

• Deletes any open SQL-XML related work tables

• Closes all system tables

• Closes all user tables

• Drops all temporary objects

• Aborts open transactions

• Defects from a distributed transaction when enlisted

• Decrements the reference count for users in current database which releases shared database locks

• Frees acquired locks

• Releases any acquired handles

• Resets all SET options to the default values

• Resets the @@rowcount value

• Resets the @@identity value

• Resets any session level trace options using dbcc traceon()

• Resets CONTEXT_INFO to NULL in SQL Server 2005 and newer _{[ not part of the original article ]}

sp_reset_connection will NOT reset:

• Security context, which is why connection pooling matches connections based on the exact connection string

• Application roles entered using sp_setapprole, since application roles could not be reverted at all prior to SQL Server 2005. Starting in SQL Server 2005, app roles can be reverted, but only with additional information that is not part of the session. Before closing the connection, application roles need to be manually reverted via sp_unsetapprole using a "cookie" value that is captured when sp_setapprole is executed.

Note: I am including the list here as I do not want it to be lost in the ever transient web.

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

I had to show a loader while pdf in iFrame is loading so what i come up with:

    loader({href:'loader.gif', onComplete: function(){
            $('#pd').html('<iframe onLoad="loader.close();" src="pdf" width="720px" height="600px" >Please wait... your report is loading..</iframe>');
    }
    });

I'm showing a loader. Once I'm sure that customer can see my loader, i'm calling onCompllet loaders method that loads an iframe. Iframe has an "onLoad" event. Once PDF is loaded it triggers onloat event where i'm hiding the loader :)

The important part:

iFrame has "onLoad" event where you can do what you need (hide loaders etc.)

There are few steps to overcome this problem:

1. Uninstall Java related softwares
2. Uninstall NodeJS if installed
3. Download java 8 update161
4. Install it

The problem solved: The problem raised to me at the uninstallation on openfire server.

All you have to do is read the code on getbootstrap.com:

Do you have the button specified as an IBOutlet in your view controller class, and is it connected properly as an outlet in Interface Builder (ctrl drag from new referencing outlet to file owner and select your UIButton object)? That's usually the problem I have when I see these symptoms.

Edit: While it's not the case here, something like this can also happen if you set an attributed title to the button, then you try to change the title and not the attributed title.

Dead horse perhaps, but a while back I was trying to do the same and came across a script to create a STP that tried to do what I was looking for, but it had a few quirks that needed some attention. In an attempt to track down where I found the script to post an update, I came across this thread and it seemed like a good spot to share it.

This STP (Which for the most part I take no credit for, and I can't find the site I found it on), takes a schema name, table name, and Y or N [to include or exclude headers] as input parameters and queries the supplied table, outputting each row in comma-separated, quoted, csv format.

I've made numerous fixes/changes to the original script, but the bones of it are from the OP, whoever that was.

Here is the script:

IF OBJECT_ID('get_csvFormat', 'P') IS NOT NULL
    DROP PROCEDURE get_csvFormat
GO

CREATE PROCEDURE get_csvFormat(@schemaname VARCHAR(20), @tablename VARCHAR(30),@header char(1))
AS
BEGIN
    IF ISNULL(@tablename, '') = ''
    BEGIN
        PRINT('NO TABLE NAME SUPPLIED, UNABLE TO CONTINUE')
        RETURN
    END
    ELSE
    BEGIN
        DECLARE @cols VARCHAR(MAX), @sqlstrs VARCHAR(MAX), @heading VARCHAR(MAX), @schemaid int

        --if no schemaname provided, default to dbo
        IF ISNULL(@schemaname, '') = ''
            SELECT @schemaname = 'dbo'

        --if no header provided, default to Y
        IF ISNULL(@header, '') = ''
            SELECT @header = 'Y'

        SELECT @schemaid = (SELECT schema_id FROM sys.schemas WHERE [name] = @schemaname)
        SELECT 
        @cols = (
            SELECT ' , CAST([', b.name + '] AS VARCHAR(50)) '  
            FROM sys.objects a 
            INNER JOIN sys.columns b ON a.object_id=b.object_id 
            WHERE a.name = @tablename AND a.schema_id = @schemaid
            FOR XML PATH('')
        ),
        @heading = (
            SELECT ',"' + b.name + '"' FROM sys.objects a 
            INNER JOIN sys.columns b ON a.object_id=b.object_id 
            WHERE a.name= @tablename AND a.schema_id = @schemaid
            FOR XML PATH('')
        )

        SET @tablename = @schemaname + '.' + @tablename
        SET @heading =  'SELECT ''' + right(@heading,len(@heading)-1) + ''' AS CSV, 0 AS Sort'  + CHAR(13)
        SET @cols =  '''"'',' + replace(right(@cols,len(@cols)-1),',', ',''","'',') + ',''"''' + CHAR(13)

        IF @header = 'Y'
            SET @sqlstrs =  'SELECT CSV FROM (' + CHAR(13) + @heading + ' UNION SELECT CONCAT(' + @cols + ') CSV, 1 AS Sort FROM ' + @tablename + CHAR(13) + ') X ORDER BY Sort, CSV ASC'
        ELSE
            SET @sqlstrs =  'SELECT CONCAT(' + @cols + ') CSV FROM ' + @tablename 

        IF @schemaid IS NOT NULL 
            EXEC(@sqlstrs)
        ELSE 
            PRINT('SCHEMA DOES NOT EXIST')
    END
END

GO

--EXEC get_csvFormat @schemaname='dbo', @tablename='TradeUnion', @header='Y'

Quick summary:

import "math/bits"
const (
    MaxUint uint = (1 << bits.UintSize) - 1
    MaxInt int = (1 << bits.UintSize) / 2 - 1
    MinInt int = (1 << bits.UintSize) / -2
)

Background:

As I presume you know, the uint type is the same size as either uint32 or uint64, depending on the platform you're on. Usually, one would use the unsized version of these only when there is no risk of coming close to the maximum value, as the version without a size specification can use the "native" type, depending on platform, which tends to be faster.

Note that it tends to be "faster" because using a non-native type sometimes requires additional math and bounds-checking to be performed by the processor, in order to emulate the larger or smaller integer. With that in mind, be aware that the performance of the processor (or compiler's optimised code) is almost always going to be better than adding your own bounds-checking code, so if there is any risk of it coming into play, it may make sense to simply use the fixed-size version, and let the optimised emulation handle any fallout from that.

With that having been said, there are still some situations where it is useful to know what you're working with.

The package "math/bits" contains the size of uint, in bits. To determine the maximum value, shift 1 by that many bits, minus 1. ie: (1 << bits.UintSize) - 1

Note that when calculating the maximum value of uint, you'll generally need to put it explicitly into a uint (or larger) variable, otherwise the compiler may fail, as it will default to attempting to assign that calculation into a signed int (where, as should be obvious, it would not fit), so:

const MaxUint uint = (1 << bits.UintSize) - 1

That's the direct answer to your question, but there are also a couple of related calculations you may be interested in.

According to the spec, uint and int are always the same size.

uint either 32 or 64 bits

int same size as uint

So we can also use this constant to determine the maximum value of int, by taking that same answer and dividing by 2 then subtracting 1. ie: (1 << bits.UintSize) / 2 - 1

And the minimum value of int, by shifting 1 by that many bits and dividing the result by -2. ie: (1 << bits.UintSize) / -2

In summary:

MaxUint: (1 << bits.UintSize) - 1

MaxInt: (1 << bits.UintSize) / 2 - 1

MinInt: (1 << bits.UintSize) / -2

full example (should be the same as below)

package main

import "fmt"
import "math"
import "math/bits"

func main() {
    var mi32 int64 = math.MinInt32
    var mi64 int64 = math.MinInt64

    var i32 uint64 = math.MaxInt32
    var ui32 uint64 = math.MaxUint32
    var i64 uint64 = math.MaxInt64
    var ui64 uint64 = math.MaxUint64
    var ui uint64 = (1 << bits.UintSize) - 1
    var i uint64 = (1 << bits.UintSize) / 2 - 1
    var mi int64 = (1 << bits.UintSize) / -2

    fmt.Printf(" MinInt32: %d\n", mi32)
    fmt.Printf(" MaxInt32:  %d\n", i32)
    fmt.Printf("MaxUint32:  %d\n", ui32)
    fmt.Printf(" MinInt64: %d\n", mi64)
    fmt.Printf(" MaxInt64:  %d\n", i64)
    fmt.Printf("MaxUint64:  %d\n", ui64)
    fmt.Printf("  MaxUint:  %d\n", ui)
    fmt.Printf("   MinInt: %d\n", mi)
    fmt.Printf("   MaxInt:  %d\n", i)
}

I ran into this when I reduced the number of user-input parameters in userInput from 3 to 1. This changed the variable output type of userInput from an array to a primitive.

Example:

myvar1 = userInput['param1']
myvar2 = userInput['param2']

to:

myvar = userInput

You can use delegate_to to run commands on your Ansible host (admin host), from where you are running your Ansible play. For example:

Delete a file if it already exists on Ansible host:

 - name: Remove file if already exists
   file:
    path: /tmp/logfile.log
    state: absent
    mode: "u+rw,g-wx,o-rwx"
   delegate_to: 127.0.0.1

Create a new file on Ansible host :

 - name: Create log file
   file:
    path: /tmp/logfile.log
    state: touch
    mode: "u+rw,g-wx,o-rwx"
   delegate_to: 127.0.0.1

Instead of using third party lib, use Java 11 isBlank()

    String str1 = "";
    String str2 = "   ";
    Character ch = '\u0020';
    String str3 =ch+" "+ch;

    System.out.println(str1.isEmpty()); //true
    System.out.println(str2.isEmpty()); //false
    System.out.println(str3.isEmpty()); //false            

    System.out.println(str1.isBlank()); //true
    System.out.println(str2.isBlank()); //true
    System.out.println(str3.isBlank()); //true

I guess it might be possible to set some kind of hardcore transition to the top style of a #container div to move your entire page in the desired direction when clicking your anchor. Something like adding a class that has top:-2000px.

I did use JQuery because I'm to lazy too use native JS, but it is not necessary for what I did.

This is probably not the best possible solution because the top content just moves towards the top and you can't get it back easily, you should definitely use JQuery if you really need that scroll animation.

DEMO

Well you could either add <a></a> tags and place the div inside it, adding an href if you want the div to act as a link. Or else just use Javascript and define an 'OnClick' function. But from the limited information provided, it's a bit hard to determine what the context of your problem is.

Let's see how we get the params, headers and body in Flask. I'm gonna explain with the help of postman.

The params keys and values are reflected in the API endpoint. for example key1 and key2 in the endpoint : https://127.0.0.1/upload?key1=value1&key2=value2

from flask import Flask, request
app = Flask(__name__)

@app.route('/upload')
def upload():

  key_1 = request.args.get('key1')
  key_2 = request.args.get('key2')
  print(key_1)
  #--> value1
  print(key_2)
  #--> value2

After params, let's now see how to get the headers:

  header_1 = request.headers.get('header1')
  header_2 = request.headers.get('header2')
  print(header_1)
  #--> header_value1
  print(header_2)
  #--> header_value2

Now let's see how to get the body

  file_name = request.files['file'].filename
  ref_id = request.form['referenceId']
  print(ref_id)
  #--> WWB9838yb3r47484

so we fetch the uploaded files with request.files and text with request.form

As your question was precious "Only this variables, not any objects. ", the answer will be also precious:

var a = 1, b = 2

a=a+b;
b=a-b;
a=a-b;

it's a trick

And as Rodrigo Assis said, it "can be shorter "

 b=a+(a=b)-b;

Demo: http://jsfiddle.net/abdennour/2jJQ2/

Just make sure you add box-sizing:border-box; to your #myWorkContent.

You need to log in with the correct username and password. Does the user root have permission to access the database? or did you create a specific user to do this?

The other issue might be that you are not using a password when trying to log in.

These code lines can help you quickly enable log setting in your magento site.

INSERT INTO `core_config_data` (`config_id`, `scope`, `scope_id`, `path`, `value`) VALUES
('', 'default', 0, 'dev/log/active', '1'),
('', 'default', 0, 'dev/log/file', 'system.log'),
('', 'default', 0, 'dev/log/exception_file', 'exception.log');

Then you can see them inside the folder: /var/log under root installation.

You can make the application fully compatible with the date and time that is used by MySql. When the application runs at runtime provide this code. First Go to the Application Events. In the list of tools

1. Go to the project
2. Project Properties
3. Select the Application tab
4. View Application Events

This will open a new file. This file contains code used at the start of the application.

Write this code in that new file:

 Partial Friend Class MyApplication

    Private Sub MyApplication_Startup(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.ApplicationServices.StartupEventArgs) Handles Me.Startup
        My.Application.ChangeCulture("en")
        My.Application.ChangeUICulture("en")
        My.Application.Culture.DateTimeFormat.ShortDatePattern = "yyyy-MM-dd"
        My.Application.Culture.DateTimeFormat.LongDatePattern = "yyyy-MM-dd"
        My.Application.Culture.DateTimeFormat.LongTimePattern = "HH:mm:ss"
        My.Application.Culture.DateTimeFormat.ShortTimePattern = "HH:mm:ss"
    End Sub


End Class

Dirk's answer is a great one. If you want an appearance like what hist produces, you can also try this:

buckets <- c(0,1,2,3,4,5,25)
mydata_hist <- hist(mydata$V3, breaks=buckets, plot=FALSE)
bp <- barplot(mydata_hist$count, log="y", col="white", names.arg=buckets)
text(bp, mydata_hist$counts, labels=mydata_hist$counts, pos=1)

The last line is optional, it adds value labels just under the top of each bar. This can be useful for log scale graphs, but can also be omitted.

I also pass main, xlab, and ylab parameters to provide a plot title, x-axis label, and y-axis label.

There's 3 satellites at least that you must be able to receive from of the 24-32 out there, and they each broadcast a time from a synchronized atomic clock. The differences in those times that you receive at any one time tell you how long the broadcast took to reach you, and thus where you are in relation to the satellites. So, it sort of reads from something, but it doesn't connect to that thing. Note that this doesn't tell you your orientation, many GPSes fake that (and speed) by interpolating data points.

If you don't count the cost of the receiver, it's a free service. Apparently there's higher resolution services out there that are restricted to military use. Those are likely a fixed cost for a license to decrypt the signals along with a confidentiality agreement.

Now your device may support GPS tracking, in which case it might communicate, say via GPRS, to a database which will store the location the device has found itself to be at, so that multiple devices may be tracked. That would require some kind of connection.

Maps are either stored on the device or received over a connection. Navigation is computed based on those maps' databases. These likely are a licensed item with a cost associated, though if you use a service like Google Maps they have the license with NAVTEQ and others.

New variables can be decalared only at block scope. You need to write something like this:

case VAL:  
  // This will work
  {
  int newVal = 42;  
  }
  break;

Of course, newVal only has scope within the braces...

This works for me on OSX:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n'

It returns the list one per line:

1.1.0rc1

1.2.0rc2
1.2.0rc3

Or to get the latest version available:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n' \
| gsort -r -V \
| head -1

1.10.0rc2

Keep in mind gsort has to be installed (on OSX) to parse the versions. You can install it with brew install coreutils

The SqlException has a Number property that you can check. For duplicate error the number is 2601.

catch (SqlException e)
{
   switch (e.Number)
   {
      case 2601:
         // Do something.
         break;
      default:
         throw;
   }
 }

To get a list of all SQL errors from you server, try this:

 SELECT * FROM sysmessages

Update

This can now be simplified in C# 6.0

catch (SqlException e) when (e.Number == 2601)
{
   // Do something.
}

if you have a date in a string with the format "ddMMyyyy" and want to convert it to "yyyyMMdd" you could do like this:

DateTime dt = DateTime.ParseExact(dateString, "ddMMyyyy", 
                                  CultureInfo.InvariantCulture);
dt.ToString("yyyyMMdd");

I have the same problem here, then I reinstalled mysql and it worked.

sudo apt-get install mysql-server mysql-common mysql-client

Let us see a more updated approach to this question:

Import AudioToolbox

func noteSelector(noteNumber: String) {

    if let soundURL = Bundle.main.url(forResource: noteNumber, withExtension: "wav") {
        var mySound: SystemSoundID = 0
        AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
        AudioServicesPlaySystemSound(mySound)
}

You can do it in one line:

ls /home/edward/bank1/fiche/Test* >/dev/null 2>&1 && echo "found one" || echo "found none"

To understand what it does you have to decompose the command and have a basic awareness of boolean logic.

Directly from bash man page:

[...]
expression1 && expression2
     True if both expression1 and expression2 are true.
expression1 || expression2
     True if either expression1 or expression2 is true.
[...]

In the shell (and in general in unix world), the boolean true is a program that exits with status 0.

ls tries to list the pattern, if it succeed (meaning the pattern exists) it exits with status 0, 2 otherwise (have a look at ls man page for details).

In our case there are actually 3 expressions, for the sake of clarity I will put parenthesis, although they are not needed because && has precedence on ||:

 (expression1 && expression2) || expression3

so if expression1 is true (ie: ls found the pattern) it evaluates expression2 (which is just an echo and will exit with status 0). In this case expression3 is never evaluate because what's on the left site of || is already true and it would be a waste of resources trying to evaluate what's on the right.

Otherwise, if expression1 is false, expression2 is not evaluated but in this case expression3 is.

Here's a method that only uses splitting and joining. It's a little more readable so thought it was worth sharing:

    String.prototype.replaceLast = function (what, replacement) {
        var pcs = this.split(what);
        var lastPc = pcs.pop();
        return pcs.join(what) + replacement + lastPc;
    };

This is very possible if you write your own helper. We are using a custom $ helper to accomplish this type of interaction (and more):

Use the built-in python function quit() and that's it. No need to import any library. I'm using python 3.4

[Update: Although I discovered this trick independently, I’ve since learned that Thierry Koblentz beat me to it. You can find his 2009 article on A List Apart. Credit where credit is due.]

I know this is an old question, but I encountered a similar problem that I did solve only with CSS. Here is my blog post that discusses the solution. Included in the post is a live example. Code is reposted below.

#container {
  display: inline-block;
  position: relative;
  width: 50%;
}

#dummy {
  margin-top: 75%;
  /* 4:3 aspect ratio */
}

#element {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: silver/* show me! */
}

<div id="container">
  <div id="dummy"></div>
  <div id="element">
    some text
  </div>
</div>

The Collection#filter method really does eager load all members. Filtering at the SQL level will be added in doctrine 2.3.

It won't throw exception, you'll get an empty list.

Easier still you can just do

for i in {00001..99999}; do
  echo $i
done

You can use typeof:

if (typeof pagetype === 'undefined') {
    // pagetype doesn't exist
}

I got the same error, I changed this

export default withAlert(Alerts)

to this

export default withAlert()(Alerts).

In older versions the former code was ok , but in later versions it throws an error. So use the later code to avoid the errror.

There's one particular case where you should take care:

user=daniel
cat > output.file << EOF
"$user"san
EOF

Will output "daniel"san, and not danielsan, as you might have wanted. In this case you should do instead:

user=daniel
cat > output.file << EOF
${user}san
EOF

delete your local branch by following command

git branch -d branch_name

you could also do

git branch -D branch_name 

which basically force a delete (even if local not merged to source)

Assuming your dataframe is mydf:

mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))

To stop the service we must use the method stopService():

  Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
  //startService(myService);
  stopService(myService);

then the method onDestroy() in the service is called:

  @Override
    public void onDestroy() {

        Log.i(TAG, "onCreate() , service stopped...");
    }

Here is a complete example including how to stop the service.

This function, based on the work by Laurenz Albe at https://www.cybertec-postgresql.com/en/index-your-foreign-key/, list all the foreign keys with missing indexes. The size of the table is shown, as for small tables the scanning performance could be superior to the index one.

-- function:    fkeys_missing_indexes
-- purpose:     list all foreing keys in the database without and index in the source table.

create or replace function oftool_fkey_missing_indexes () 
returns table (
  src_table     regclass,
  fk_columns    varchar,
  table_size    varchar,
  fk_constraint name,
  dst_table     regclass
)
as $$
select
  -- source table having ta foreign key declaration
  tc.conrelid::regclass as src_table,
  
  -- ordered list of foreign key columns
  string_agg(ta.attname, ',' order by tx.n) as fk_columns,
  
  -- source table size
  pg_catalog.pg_size_pretty (
    pg_catalog.pg_relation_size(tc.conrelid)
  ) as table_size,
  
  -- name of the foreign key constraint
  tc.conname as fk_constraint,
  
  -- name of the target or destination table
  tc.confrelid::regclass as dst_table
  
from pg_catalog.pg_constraint tc

-- enumerated key column numbers per foreign key
cross join lateral unnest(tc.conkey) with ordinality as tx(attnum, n)

-- name for each key column
join pg_catalog.pg_attribute ta on ta.attnum = tx.attnum and ta.attrelid = tc.conrelid

where not exists (
  -- is there ta matching index for the constraint?
  select 1 from pg_catalog.pg_index i
  where 
    i.indrelid = tc.conrelid and 
    -- the first index columns must be the same as the key columns, but order doesn't matter
    (i.indkey::smallint[])[0:cardinality(tc.conkey)-1] @> tc.conkey) and 
    tc.contype = 'f'
  group by 
    tc.conrelid, 
    tc.conname, 
    tc.confrelid
  order by 
    pg_catalog.pg_relation_size(tc.conrelid) desc;
$$ language sql;

test it this way,

select * from oftool_fkey_missing_indexes();

you'll see a list like this.
