If you have red squiggles underneath the project in the Maven plugin, try clicking the "Reimport All Maven Projects" button (looks like a refresh symbol).

This error shows up when using the maven-install-plugin version 3.0.0-M1 (or similar)

As already mentioned above and also here the following plug-in version works:

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-install-plugin</artifactId>
        <version>2.5.2</version>
    </plugin>

If you're using ZLib in your project, then you need to find :

#if 1

in zconf.h and replace(uncomment) it with :

#if HAVE_UNISTD_H /* ...the rest of the line

If it isn't ZLib I guess you should find some alternative way to do this. GL.

em's are the way forward, not just for fonts but you can use them with boxes, line thickness and other stuff too, why?

Put simply em's are the only ones that scale in unison with the alt+ and alt- keys in the browser for zooming.

Other measurements scale, but not as cleanly as an em.

On a side note if you want the best in scaling, also convert your graphics to vector based SVG where possible too as these will also cleanly scale with the browsers zoom ratio.

You can use ObjectMapper.convertValue(), either value by value or even for the whole list. But you need to know the type to convert to:

POJO pojo = mapper.convertValue(singleObject, POJO.class);
// or:
List<POJO> pojos = mapper.convertValue(listOfObjects, new TypeReference<List<POJO>>() { });

this is functionally same as if you did:

byte[] json = mapper.writeValueAsBytes(singleObject);
POJO pojo = mapper.readValue(json, POJO.class);

but avoids actual serialization of data as JSON, instead using an in-memory event sequence as the intermediate step.

You can create a list,

ArrayList<String[]> outerArr = new ArrayList<String[]>(); 

and add other lists to it like so:

String[] myString1= {"hey","hey","hey","hey"};  
outerArr .add(myString1);
String[] myString2= {"you","you","you","you"};
outerArr .add(myString2);

Now you can use the double loop below to show everything inside all lists

for(int i=0;i<outerArr.size();i++){

   String[] myString= new String[4]; 
   myString=outerArr.get(i);
   for(int j=0;j<myString.length;j++){
      System.out.print(myString[j]); 
   }
   System.out.print("\n");

}

In Gecko/WebKit-based browsers (Firefox, Chrome and Safari) and Opera, you can use btoa() and atob().

Original answer: How can you encode a string to Base64 in JavaScript?

A moving average can also be calculated and visualized directly in a line chart by using the following code:

Example using stock price data:

import pandas_datareader.data as web
import matplotlib.pyplot as plt
import datetime
plt.style.use('ggplot')

# Input variables
start = datetime.datetime(2016, 1, 01)
end = datetime.datetime(2018, 3, 29)
stock = 'WFC'

# Extrating data
df = web.DataReader(stock,'morningstar', start, end)
df = df['Close']

print df 

plt.plot(df['WFC'],label= 'Close')
plt.plot(df['WFC'].rolling(9).mean(),label= 'MA 9 days')
plt.plot(df['WFC'].rolling(21).mean(),label= 'MA 21 days')
plt.legend(loc='best')
plt.title('Wells Fargo\nClose and Moving Averages')
plt.show()

Your list just contains a string. Convert it to integer IDs:

L = ['350882 348521 350166\r\n']

ids = [int(i) for i in L[0].strip().split()]
print(ids)
id = 348521
if id not in ids:
    ids.append(id)
print(ids)
id = 348522
if id not in ids:
    ids.append(id)
print(ids)
# Turn it back into your odd format
L = [' '.join(str(id) for id in ids) + '\r\n']
print(L)

Output:

[350882, 348521, 350166]
[350882, 348521, 350166]
[350882, 348521, 350166, 348522]
['350882 348521 350166 348522\r\n']

Finally, i solved the problem by using following way, in which the position of the spinner can be get by its string

private int getPostiton(String locationid,Cursor cursor)
{
    int i;
    cursor.moveToFirst(); 
    for(i=0;i< cursor.getCount()-1;i++)
    {  

        String locationVal = cursor.getString(cursor.getColumnIndex(RoadMoveDataBase.LT_LOCATION));  
        if(locationVal.equals(locationid))
        { 
            position = i+1;  
            break;
        }
        else
        {
            position = 0;
        }
        cursor.moveToNext();  
    } 

Calling the method

    Spinner location2 = (Spinner)findViewById(R.id.spinner1);
    int location2id = getPostiton(cursor.getString(3),cursor);
    location2.setSelection(location2id);

I hope it will help for some one..

Actually if you do Ctrl+W W, you won't need to add that extra Ctrl. Does the same thing.

Whilst the most upvoted answer is correct but it lacks usage of multi-core processing. In my case, having 12 cores I use PLink:

Parallel.ForEach(
    File.ReadLines(filename), //returns IEumberable<string>: lazy-loading
    new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount },
    (line, state, index) =>
    {
        //process line value
    }
);

Worth mentioning, I got that as an interview question asking return Top 10 most occurrences:

var result = new ConcurrentDictionary<string, int>(StringComparer.InvariantCultureIgnoreCase);
Parallel.ForEach(
    File.ReadLines(filename),
    new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount },
    (line, state, index) =>
    {
        result.AddOrUpdate(line, 1, (key, val) => val + 1);        
    }
);

return result
    .OrderByDescending(x => x.Value)
    .Take(10)
    .Select(x => x.Value);

Benchmarking: BenchmarkDotNet=v0.12.1, OS=Windows 10.0.19042 Intel Core i7-8700K CPU 3.70GHz (Coffee Lake), 1 CPU, 12 logical and 6 physical cores [Host] : .NET Framework 4.8 (4.8.4250.0), X64 RyuJIT DefaultJob : .NET Framework 4.8 (4.8.4250.0), X64 RyuJIT

And as you can see it's 75% performance improvement.

Run the following code:

du -sh /var/log/mysql

Perhaps mysql binary logs filled the memory, If so, follow the removal of old logs and restart the server. Also add in my.cnf:

expire_logs_days = 3

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

Simply enough:

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

Will print the received HTTP response.

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

I had a similar issue. On some devices after a while Android kills my service and even startForeground() does not help. And my customer does not like this issue. My solution is to use AlarmManager class to make sure that the service is running when it's necessary. I use AlarmManager to create a kind of watchdog timer. It checks from time to time if the service should be running and restart it. Also I use SharedPreferences to keep the flag whether the service should be running.

Creating/dismissing my watchdog timer:

void setServiceWatchdogTimer(boolean set, int timeout)
{
    Intent intent;
    PendingIntent alarmIntent;
    intent = new Intent(); // forms and creates appropriate Intent and pass it to AlarmManager
    intent.setAction(ACTION_WATCHDOG_OF_SERVICE);
    intent.setClass(this, WatchDogServiceReceiver.class);
    alarmIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
    if(set)
        am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + timeout, alarmIntent);
    else
        am.cancel(alarmIntent);
}

Receiving and processing the intent from the watchdog timer:

/** this class processes the intent and
 *  checks whether the service should be running
 */
public static class WatchDogServiceReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {

        if(intent.getAction().equals(ACTION_WATCHDOG_OF_SERVICE))
        {
            // check your flag and 
            // restart your service if it's necessary
            setServiceWatchdogTimer(true, 60000*5); // restart the watchdogtimer
        }
    }
}

Indeed I use WakefulBroadcastReceiver instead of BroadcastReceiver. I gave you the code with BroadcastReceiver just to simplify it.

Of course you can, just use setTimeout to change a class or something to trigger the transition.

HTML:

<p id="aap">OHAI!</p>

CSS:

p {
    opacity:1;
    transition:opacity 500ms;
}
p.waa {
    opacity:0;
}

JS to run on load or DOMContentReady:

setTimeout(function(){
    document.getElementById('aap').className = 'waa';
}, 5000);

Example fiddle here.

try this

bool focus = false;
private void Form1_Paint(object sender, PaintEventArgs e)
{
    if (focus)
    {
        textBox1.BorderStyle = BorderStyle.None;
        Pen p = new Pen(Color.Red);
        Graphics g = e.Graphics;
        int variance = 3;
        g.DrawRectangle(p, new Rectangle(textBox1.Location.X - variance, textBox1.Location.Y - variance, textBox1.Width + variance, textBox1.Height +variance ));
    }
    else
    {
        textBox1.BorderStyle = BorderStyle.FixedSingle;
    }
}

private void textBox1_Enter(object sender, EventArgs e)
{
    focus = true;
    this.Refresh();
}

private void textBox1_Leave(object sender, EventArgs e)
{
    focus = false;
    this.Refresh();
}

I put together an R package zeallot to tackle this problem. zeallot includes a multiple assignment or unpacking assignment operator, %<-%. The LHS of the operator is any number of variables to assign, built using calls to c(). The RHS of the operator is a vector, list, data frame, date object, or any custom object with an implemented destructure method (see ?zeallot::destructure).

Here are a handful of examples based on the original post,

library(zeallot)

functionReturningTwoValues <- function() { 
  return(c(1, 2)) 
}

c(a, b) %<-% functionReturningTwoValues()
a  # 1
b  # 2

functionReturningListOfValues <- function() {
  return(list(1, 2, 3))
}

c(d, e, f) %<-% functionReturningListOfValues()
d  # 1
e  # 2
f  # 3

functionReturningNestedList <- function() {
  return(list(1, list(2, 3)))
}

c(f, c(g, h)) %<-% functionReturningNestedList()
f  # 1
g  # 2
h  # 3

functionReturningTooManyValues <- function() {
  return(as.list(1:20))
}

c(i, j, ...rest) %<-% functionReturningTooManyValues()
i     # 1
j     # 2
rest  # list(3, 4, 5, ..)

Check out the package vignette for more information and examples.

I like Imagemagick. http://www.imagemagick.org/script/api.php

svn checkout to revision where your repository is on another server

Use svn log command to find out which revisions are available:

svn log

Which prints:

------------------------------------------------------------------------
r762 | machines | 2012-12-02 13:00:16 -0500 (Sun, 02 Dec 2012) | 2 lines

------------------------------------------------------------------------
r761 | machines | 2012-12-02 12:59:40 -0500 (Sun, 02 Dec 2012) | 2 lines

Note the number r761. Here is the command description:

svn export http://url-to-your-file@761 /tmp/filename

I used this command specifically:

svn export svn+ssh://[email protected]/home1/oct/calc/calcFeatures.m@761 calcFeatures.m

Which causes calcFeatures.m revision 761 to be checked out to the current directory.

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

The following worked for me

import java.time.*;
import java.time.format.*;

public class Times {

  public static void main(String[] args) {
    final String dateTime = "2012-02-22T02:06:58.147Z";
    DateTimeFormatter formatter = DateTimeFormatter.ISO_INSTANT;
    final ZonedDateTime parsed = ZonedDateTime.parse(dateTime, formatter.withZone(ZoneId.of("UTC")));
    System.out.println(parsed.toLocalDateTime());
  }
}

and gave me output as

2012-02-22T02:06:58.147

you cannot access array (php array) from js try

<?php
$array = array(1,2,3,4,5,6);
echo implode('~',$array);
?>

and js

$(document).ready( function() {
$('#prev').click(function() {
  $.ajax({
  type: 'POST',
  url: 'ajax.php',
  data: 'id=testdata',
  cache: false,
  success: function(data) {
    result=data.split('~');
    $('#content1').html(result[0]);
  },
  });
});
});

If including a library is overkill here is a solution that is guaranteed to work.

$('div').click(function() {
    $(this).css('background-color','#FFFFCC');
    setTimeout(function() { $(this).fadeOut('slow').fadeIn('slow'); } , 1000); 
    setTimeout(function() { $(this).css('background-color','#FFFFFF'); } , 1000); 
});

1. Setup event trigger

2. Set the background color of block element

3. Inside setTimeout use fadeOut and fadeIn to create a little animation effect.

4. Inside second setTimeout reset default background color

   Tested in a few browsers and it works nicely.

Dear olga is clear what the message says. Turn off the custom errors to see the details about this error for fix it, and then you close them back. So add mode="off" as:

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

Relative answer: Deploying website: 500 - Internal server error

By the way: The error message declare that the web.config is not the one you type it here. Maybe you have forget to upload your web.config ? And remember to close the debug flag on the web.config that you use for online pages.

I had the same issue. I think it was a deadlock issue with SQL. You can just force close the SQL process from Task Manager. If that didn't fix it, just restart your computer. You don't need to drop the table and reload the data.

process.cwd() returns the current working directory,

i.e. the directory from which you invoked the node command.

__dirname returns the directory name of the directory containing the JavaScript source code file

Use sys.getsizeof to get the size of an object, in bytes.

>>> from sys import getsizeof
>>> a = 42
>>> getsizeof(a)
12
>>> a = 2**1000
>>> getsizeof(a)
146
>>>

Note that the size and layout of an object is purely implementation-specific. CPython, for example, may use totally different internal data structures than IronPython. So the size of an object may vary from implementation to implementation.

This has nothing to do with structs - arrays in C are not assignable:

char a[20];
a = "foo";   // error

you need to use strcpy:

strcpy( a, "foo" );

or in your code:

strcpy( sara.first, "Sara" );

<%@page import="java.text.SimpleDateFormat"%>
<%@page import="java.util.Date"%>
<%@page import="java.util.Locale"%>

String stringDate = "Fri May 13 2011 19:59:09 GMT 0530";
Date stringDate1 = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss Z", Locale.ENGLISH).parse(stringDate);
String stringDate2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(stringDate1);

With Bootstrap >4.1 it's just a case of using the flexbox utility classes. Just have a flexbox container inside your column, and then give all the elements within it the "flex-fill" class. As with inline forms you'll need to set the margins/padding on the elements yourself.

.prop-label {_x000D_
    margin: .25rem 0 !important;_x000D_
}_x000D_
_x000D_
.prop-field {_x000D_
    margin-left: 1rem;_x000D_
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<div class="row">_x000D_
 <div class="col-12">_x000D_
  <div class="d-flex">_x000D_
   <label class="flex-fill prop-label">Label:</label>_x000D_
   <input type="text" class="flex-fill form-control prop-field">_x000D_
  </div>_x000D_
 </div>_x000D_
</div>

Try maybe this way

try{
    double d= Double.valueOf(someString);
    if (d==(int)d){
        System.out.println("integer"+(int)d);
    }else{
        System.out.println("double"+d);
    }
}catch(Exception e){
    System.out.println("not number");
}

But all numbers outside Integers range (like "-1231231231231231238") will be treated as doubles. If you want to get rid of that problem you can try it this way

try {
    double d = Double.valueOf(someString);
    if (someString.matches("\\-?\\d+")){//optional minus and at least one digit
        System.out.println("integer" + d);
    } else {
        System.out.println("double" + d);
    }
} catch (Exception e) {
    System.out.println("not number");
}

The stringr package provides the str_sub function, which is a bit easier to use than substr, especially if you want to extract right portions of your string :

R> str_sub("leftright",1,4)
[1] "left"
R> str_sub("leftright",-5,-1)
[1] "right"

If you want to create a small dots, just use icon from font awesome.

fa fa-circle

You could create a patch from the commits that you want to copy and apply the patch to the destination branch.

You could read the html file manually and then use loadData or loadDataWithBaseUrl methods of WebView to show it.

Try to use app:maxImageSize="56dp" instead of the above answers after you update your support library to v28.0.0

The slice() method returns a copy of a portion of an array into a new array object.

$scope.participantForms.slice(index, 1);

This does NOT change the participantForms array but returns a new array containing the single element found at the index position in the original array.

The splice() method changes the content of an array by removing existing elements and/or adding new elements.

$scope.participantForms.splice(index, 1);

This will remove one element from the participantForms array at the index position.

These are the Javascript native functions, AngularJS has nothing to do with them.

toFixed will behave like round.

For a floor like behavior use %:

var num = 3.834234;
var floored_num = num - (num % 1); // floored_num will be 3

What worked for me was following : (eclipse 3.3.6 Subclipse 2.4)

• set svn:ignore property via tortoise : ( .settings .classpath .project target .apt_src one item at one line)
• deleted the project from the eclipse
• fresh checkout from the svn
• import the project in eclipse (simple reimporting the project in eclipse did not worked for me)

f = ... # file-like object, i.e. supporting read(size) function and 
        # returning empty string '' when there is nothing to read

def chunked(file, chunk_size):
    return iter(lambda: file.read(chunk_size), '')

for data in chunked(f, 65536):
    # process the data

UPDATE: The approach is best explained in https://stackoverflow.com/a/4566523/38592

When clicking on the button for search you can find it without a loop.
Just add to the option an attribute with the value you need (like id) and search for it specific.

$('#search_wrapper button').on('click', function(){
console.log($('option[value="'+ 
$('#autocomplete_input').val() +'"]').data('value'));
})

I suspect you forget to export PATH, anaconda/bin must be added in your $PATH. (Linux, OSX common problem). On Windows make sure you run install and commands as administrator.

I did experience this error when I tried doing an WHERE EXIST where the subquery matched 2 columns that accidentially was different types. The two tables was also different storage engines.

One column was a CHAR (90) and the other was a BIGINT (20).

One table was InnoDB and the other was MEMORY.

Part of query:

[...] AND EXISTS (select objectid from temp_objectids where temp_objectids.objectid = items_raw.objectid );

Changing the column type on the one column from BIGINT to CHAR solved the issue.

then i simply do a select query for every schema :

SELECT disable_triggers(true,'public');
SELECT disable_triggers(true,'Adempiere');

Minimal code needed for this one. Create a common 'key' to cartesian merge the two:

df1['key'] = 0
df2['key'] = 0

df_cartesian = df1.merge(df2, how='outer')

type normal division first and then type shift + S->d

The documentation could help you : http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/DocumentBuilder.html

The method DocumentBuilder.parse(String) takes a URI and tries to open it. If you want to directly give the content, you have to give it an InputStream or Reader, for example a StringReader. ... Welcome to the Java standard levels of indirections !

Basically :

DocumentBuilder db = ...;
String xml = ...;
db.parse(new InputSource(new StringReader(xml)));

Note that if you read your XML from a file, you can directly give the File object to DocumentBuilder.parse() .

As a side note, this is a pattern you will encounter a lot in Java. Usually, most API work with Streams more than with Strings. Using Streams means that potentially not all the content has to be loaded in memory at the same time, which can be a great idea !

Try adding the following middleware to your NodeJS/Express app (I have added some comments for your convenience):

// Add headers
app.use(function (req, res, next) {

    // Website you wish to allow to connect
    res.setHeader('Access-Control-Allow-Origin', 'http://localhost:8888');

    // Request methods you wish to allow
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');

    // Request headers you wish to allow
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');

    // Set to true if you need the website to include cookies in the requests sent
    // to the API (e.g. in case you use sessions)
    res.setHeader('Access-Control-Allow-Credentials', true);

    // Pass to next layer of middleware
    next();
});

Hope that helps!

This should work:

$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`

Creating SubString (prefix and suffix) from String using Swift 4:

let str : String = "ilike"
for i in 0...str.count {
    let index = str.index(str.startIndex, offsetBy: i) // String.Index
    let prefix = str[..<index] // String.SubSequence
    let suffix = str[index...] // String.SubSequence
    print("prefix \(prefix), suffix : \(suffix)")
}

Output

prefix , suffix : ilike
prefix i, suffix : like
prefix il, suffix : ike
prefix ili, suffix : ke
prefix ilik, suffix : e
prefix ilike, suffix : 

If you want to generate a substring between 2 indices , use :

let substring1 = string[startIndex...endIndex] // including endIndex
let subString2 = string[startIndex..<endIndex] // excluding endIndex

Turns out it needs to be specified via escaped unicode. This question is related and contains the answer.

The solution:

h2:after {
    content: "\00a0";
}

The problem

IE<=8 simply doesn't have an indexOf() method for arrays.

The solution

If you need indexOf in IE<=8, you should consider using the following polyfill, which is recommended at the MDN :

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(searchElement, fromIndex) {
        var k;
        if (this == null) {
            throw new TypeError('"this" is null or not defined');
        }
        var o = Object(this);
        var len = o.length >>> 0;
        if (len === 0) {
            return -1;
        }
        var n = +fromIndex || 0;
        if (Math.abs(n) === Infinity) {
            n = 0;
        }
        if (n >= len) {
            return -1;
        }
        k = Math.max(n >= 0 ? n : len - Math.abs(n), 0);
        while (k < len) {
            if (k in o && o[k] === searchElement) {
                return k;
            }
            k++;
        }
        return -1;
    };
}

Minified :

Array.prototype.indexOf||(Array.prototype.indexOf=function(r,t){var n;if(null==this)throw new TypeError('"this" is null or not defined');var e=Object(this),i=e.length>>>0;if(0===i)return-1;var a=+t||0;if(Math.abs(a)===1/0&&(a=0),a>=i)return-1;for(n=Math.max(a>=0?a:i-Math.abs(a),0);i>n;){if(n in e&&e[n]===r)return n;n++}return-1});

Make a script like this:

#!/bin/bash

echo $((0x$1)).$((0x$2)).$((0x$3)).$((0x$4))

Example:

sh converthextoip.sh c0 a8 00 0b

Result:

192.168.0.11

Even though they are separate windows but the request you send from Postman, it's details should be available in network tab of developer tools. Just make sure you are not sending any other http traffic during that time, just for clarity.

In cases where you are hosting a Wordpress site on Linux and have server access you can save some headaches by installing msmtp which allows you to send via smtp from the standard php mail() function. msmtp is a simpler alternative to postfix which requires a bit more configuration.

Here are the steps:

Install msmtp

sudo apt-get install msmtp-mta ca-certificates

Create a new configuration file:

sudo nano /etc/msmtprc

...with the following configuration information:

# Set defaults.    
defaults

# Enable or disable TLS/SSL encryption.
tls on
tls_starttls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt

# Set up a default account's settings.
account default
host <smtp.example.net>
port 587
auth on
user <[email protected]>
password <password>
from <[email protected]>
syslog LOG_MAIL

You need to replace the configuration data represented by everything within "<" and ">" (inclusive, remove these). For host/username/password, use your normal credentials for sending mail through your mail provider.

Tell PHP to use it

sudo nano /etc/php5/apache2/php.ini

Add this single line:

sendmail_path = /usr/bin/msmtp -t

Complete documention can be found here:

https://marlam.de/msmtp/

Use \n for a line break and \t if you want to insert a tab.

You can also use some XML tags for basic formatting: <b> for bold text, <i> for italics, and <u> for underlined text.

Other formatting options are shown in this article on the Android Developers' site:
https://developer.android.com/guide/topics/resources/string-resource.html#FormattingAndStyling

The functionality of map and filter was intentionally changed to return iterators, and reduce was removed from being a built-in and placed in functools.reduce.

So, for filter and map, you can wrap them with list() to see the results like you did before.

>>> def f(x): return x % 2 != 0 and x % 3 != 0
...
>>> list(filter(f, range(2, 25)))
[5, 7, 11, 13, 17, 19, 23]
>>> def cube(x): return x*x*x
...
>>> list(map(cube, range(1, 11)))
[1, 8, 27, 64, 125, 216, 343, 512, 729, 1000]
>>> import functools
>>> def add(x,y): return x+y
...
>>> functools.reduce(add, range(1, 11))
55
>>>

The recommendation now is that you replace your usage of map and filter with generators expressions or list comprehensions. Example:

>>> def f(x): return x % 2 != 0 and x % 3 != 0
...
>>> [i for i in range(2, 25) if f(i)]
[5, 7, 11, 13, 17, 19, 23]
>>> def cube(x): return x*x*x
...
>>> [cube(i) for i in range(1, 11)]
[1, 8, 27, 64, 125, 216, 343, 512, 729, 1000]
>>>

They say that for loops are 99 percent of the time easier to read than reduce, but I'd just stick with functools.reduce.

Edit: The 99 percent figure is pulled directly from the What’s New In Python 3.0 page authored by Guido van Rossum.

If you also want to preserve the original file name, try with:

wget --content-disposition --trust-server-names -i list_of_urls.txt

There is a system function called ISNUMERIC for SQL 2008 and up. An example:

SELECT myCol
FROM mTable
WHERE ISNUMERIC(myCol)<> 1;

I did a couple of quick tests and also looked further into the docs:

ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0.

Which means it is fairly predictable for example

-9879210433 would pass but 987921-0433 does not. $9879210433 would pass but 9879210$433 does not.

So using this information you can weed out based on the list of valid currency symbols and + & - characters.

A simple rule for us to remember what to use in which case:

• [S]ingle quotes are for [S]trings ; [D]ouble quotes are for [D]atabase identifiers;

In MySQL and MariaDB, the ` (backtick) symbol is the same as the " symbol. You can use " when your SQL_MODE has ANSI_QUOTES enabled.

Pandas concat vs append vs join vs merge

• Concat gives the flexibility to join based on the axis( all rows or all columns)

• Append is the specific case(axis=0, join='outer') of concat

• Join is based on the indexes (set by set_index) on how variable =['left','right','inner','couter']

• Merge is based on any particular column each of the two dataframes, this columns are variables on like 'left_on', 'right_on', 'on'

repeated = str + str + str;

Sometimes simple is best. Everyone reading the code can see what's happening.

And the compiler will do the fancy stuff with StringBuilder behind the scenes for you.

$SQL_Part="("
$i=0;
while ($i<length($cat)-1)
{
   $SQL_Part+=$cat[i]+",";
}
$SQL_Part=$SQL_Part+$cat[$i+1]+")"

$SQL="SELECT * FROM products WHERE catid IN "+$SQL_Part;

It's more generic and will fit for any array!!

I'm also coming from Ruby so I love the syntax foo ||= 7.

This is the closest thing I can find.

foo = foo if 'foo' in vars() else 7

I've seen people do this for a dict:

try:
    foo['bar']
except KeyError:
    foo['bar'] = 7

Upadate: However, I recently found this gem:

foo['bar'] = foo.get('bar', 7)

If you like that, then for a regular variable you could do something like this:

vars()['foo'] = vars().get('foo', 7)

You can look at phpinfo() or check if any of the functions of memcache is available. Ultimately, check whether the Memcache class exists or not.

e.g.

if(class_exists('Memcache')){
  // Memcache is enabled.
}

This may or not help someone, but it might be a quick reference. This is also similar to all the answers presented above.

I have a lot of locations that generate list using the structure below:

return (
    {myList.map(item => (
       <>
          <div class="some class"> 
             {item.someProperty} 
              ....
          </div>
       </>
     )}
 )
         

After a little trial and error (and some frustrations), adding a key property to the outermost block resolved it. Also, note that the <> tag is now replaced with the <div> tag now.

return (
  
    {myList.map((item, index) => (
       <div key={index}>
          <div class="some class"> 
             {item.someProperty} 
              ....
          </div>
       </div>
     )}
 )

Of course, I've been naively using the iterating index (index) to populate the key value in the above example. Ideally, you'd use something which is unique to the list item.

WordUtils.capitalize(java.lang.String) from Apache Commons.

At the first site is a dropdown field to select the language of phpmyadmin.

In the config.inc.php you can set:

$cfg['Lang'] = '';

More details you can find in the documentation: http://www.phpmyadmin.net/documentation/

This will verify if the function exists, if so it will be executed

me.onChange && me.onChange(str);

Thus the error TypeError: me.onChange is not a function is prevent.

The Difference

There are a few characters which can indicate a new line. The usual ones are these two:

* '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF).
* '\r' or '0x0D' (13 in decimal) -> This one is called "Carriage return" (CR).

Different Operating Systems handle newlines in a different way. Here is a short list of the most common ones:

* DOS and Windows

They expect a newline to be the combination of two characters, namely '\r\n' (or 13 followed by 10).

* Unix (and hence Linux as well)

Unix uses a single '\n' to indicate a new line.

* Mac

Macs use a single '\r'.

Taken from Here

Quickly : you can do :

// Fixed-size list
List list = Arrays.asList(array);

// Growable list
list = new LinkedList(Arrays.asList(array));

// Duplicate elements are discarded
Set set = new HashSet(Arrays.asList(array));

and to reverse

// Create an array containing the elements in a list
Object[] objectArray = list.toArray();
MyClass[] array = (MyClass[])list.toArray(new MyClass[list.size()]);

// Create an array containing the elements in a set
objectArray = set.toArray();
array = (MyClass[])set.toArray(new MyClass[set.size()]);

Use getRGB(), it helps ( no complicated programs )

Returns an array of integer pixels in the default RGB color model (TYPE_INT_ARGB) and default sRGB color space, from a portion of the image data.

On your list view, use setOnItemClickListener

This function should work whichever the locale and currency settings :

function getNumPrice(price, decimalpoint) {
    var p = price.split(decimalpoint);
    for (var i=0;i<p.length;i++) p[i] = p[i].replace(/\D/g,'');
    return p.join('.');
}

This assumes you know the decimal point character (in my case the locale is set from PHP, so I get it with <?php echo cms_function_to_get_decimal_point(); ?>).

read will return bytes. At least for Python 3, if you want to return a string, you have to decode using the right encoding:

import boto3

s3 = boto3.resource('s3')

obj = s3.Object(bucket, key)
obj.get()['Body'].read().decode('utf-8') 

This is really the same solution as faester's solution and Bill Moon's, but here's how you do it with PowerShell:

Import-Module Servermanager
Add-WindowsFeature AS-HTTP-Activation

Of course, there's nothing stopping you from calling DISM from PowerShell either.

Since the original question was about jQuery.get, it is worth mentioning here that (as mentioned here) one could use async: false in a $.get() but ideally avoid it since asynchronous XMLHTTPRequest is deprecated (and the browser may give a warning):

$.get({
  url: url,// mandatory
  data: data,
  success: success,
  dataType: dataType,
  async:false // to make it synchronous
});

Close the target folder and its file you have opened before mvn clean

I did it like this in Internet Explorer.

function getWindowRelativeOffset(parentWindow, elem) {
    var offset = {
        left : 0,
        top : 0
    };
    // relative to the target field's document
    offset.left = elem.getBoundingClientRect().left;
    offset.top = elem.getBoundingClientRect().top;
    // now we will calculate according to the current document, this current
    // document might be same as the document of target field or it may be
    // parent of the document of the target field
    var childWindow = elem.document.frames.window;
    while (childWindow != parentWindow) {
        offset.left = offset.left + childWindow.frameElement.getBoundingClientRect().left;
        offset.top = offset.top + childWindow.frameElement.getBoundingClientRect().top;
        childWindow = childWindow.parent;
    }

    return offset;
};

=================== you can call it like this

getWindowRelativeOffset(top, inputElement);

I focus on IE only as per my focus but similar things can be done for other browsers.

If you take 5 minutes to download visual studio and make a Console Application for this, your problem is solved.

using System;
using System.Linq;
using System.Diagnostics;
using System.IO;

namespace BgRunner
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Starting: " + String.Join(" ", args));
            String arguments = String.Join(" ", args.Skip(1).ToArray());
            String command = args[0];

            Process p = new Process();
            p.StartInfo = new ProcessStartInfo(command);
            p.StartInfo.Arguments = arguments;
            p.StartInfo.WorkingDirectory = Path.GetDirectoryName(command);
            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.UseShellExecute = false;
            p.Start();
        }
    }
}

Examples of usage:

BgRunner.exe php/php-cgi -b 9999
BgRunner.exe redis/redis-server --port 3000
BgRunner.exe nginx/nginx

The important part are these CSS media queries:

<link rel="stylesheet" media="all and (max-device-width: 480px)" href="iphone.css"> 
<link rel="stylesheet" media="all and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:portrait)" href="ipad-portrait.css"> 
<link rel="stylesheet" media="all and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:landscape)" href="ipad-landscape.css"> 
<link rel="stylesheet" media="all and (min-device-width: 1025px)" href="ipad-landscape.css"> 

  public void ReadXmlFile()
    {
        string path = HttpContext.Current.Server.MapPath("~/App_Data"); // Finds the location of App_Data on server.
        XmlTextReader reader = new XmlTextReader(System.IO.Path.Combine(path, "XMLFile7.xml")); //Combines the location of App_Data and the file name
        while (reader.Read())
        {
            switch (reader.NodeType)
            {
                case XmlNodeType.Element:
                    break;
                case XmlNodeType.Text:
                    columnNames.Add(reader.Value);
                    break;
                case XmlNodeType.EndElement:
                    break;
            }
        }
    }

You can avoid the first statement and just specify the path name in constructor of XmlTextReader.

The new :is() CSS pseudo-class can do it in one selector:

:is(h1, h2, h3, h4, h5, h6) {
  color: red;
}

The answer is that #1 is technically correct based on the real meaning of the Mega prefix, however (and in life there is always a however) the math for that doesn't come out so nice in base 2, which is how computers count, so #2 is what people really use.

What went wrong?

When you include jQuery the first time:

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.11.0/jquery-ui.js"></script>

The second script plugs itself into jQuery, and "adds" $(...).datepicker.

But then you are including jQuery once again:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>

It undoes the plugging in and therefore $(...).datepicker becomes undefined.

Although the first $(document).ready block appears before that, the anonymous callback function body is not executed until all scripts are loaded, and by then $(...) (window.$ to be precise) is referring to the most recently loaded jQuery.

You would not run into this if you called $('.dateinput').datepicker immediately rather than in $(document).ready callback, but then you'd need to make sure that the target element (with class dateinput) is already in the document before the script, and it's generally advised to use the ready callback.

Solution

If you want to use datepicker from jquery-ui, it would probably make most sense to include the jquery-ui script after bootstrap. jquery-ui 1.11.4 is compatible with jquery 1.6+ so it will work fine.

Alternatively (in particular if you are not using jquery-ui for anything else), you could try bootstrap-datepicker.

For devices with iOS 7.1 or later, you need to add:

yourUILabel.layer.masksToBounds = YES;
yourUILabel.layer.cornerRadius = 8.0;

check your path ,this error will come if file was not exist into given path.

Although your answer has many solutions I think this is a great way to save lines of code. Try using spans which is great for situations like yours.

1. Create a class for making any item bold. So for paragraph text it would be

span.bold(This name can be anything do not include parenthesis) {
   font-weight: bold;
}

1. In your html you can access that class like by using the span tags and adding a class of bold or whatever name you have chosen

For JUnit 5.x it's:

java -jar junit-platform-console-standalone-<version>.jar <Options>

Find a brief summary at https://stackoverflow.com/a/52373592/1431016 and full details at https://junit.org/junit5/docs/current/user-guide/#running-tests-console-launcher

For JUnit 4.X it's really:

java -cp .:/usr/share/java/junit.jar org.junit.runner.JUnitCore [test class name]

But if you are using JUnit 3.X note the class name is different:

java -cp .:/usr/share/java/junit.jar junit.textui.TestRunner [test class name]

You might need to add more JARs or directories with your class files to the classpath and separate that with semicolons (Windows) or colons (UNIX/Linux). It depends on your environment.

Edit: I've added current directory as an example. Depends on your environment and how you build your application (can be bin/ or build/ or even my_application.jar etc). Note Java 6+ does support globs in classpath, you can do:

java -cp lib/*.jar:/usr/share/java/junit.jar ...

Hope it helps. Write tests! :-)

You're close.

The LIKE operator works with strings (CHAR, NVARCHAR, etc). so you need to concattenate the '%' symbol to the string...

MS SQL Server:

SELECT * FROM table1,table2 WHERE table1.x LIKE table2.y + '%'

Use of LIKE, however, is often slower than other operations. It's useful, powerful, flexible, but has performance considerations. I'll leave those for another topic though :)

EDIT:

I don't use MySQL, but this may work...

SELECT * FROM table1,table2 WHERE table1.x LIKE CONCAT(table2.y, '%')

        remove { CommandManager.RequerySuggested -= value; }
    }

    /// <summary>
    /// Forcess checking if execute is allowed
    /// </summary>
    /// <param name="parameter"></param>
    /// <returns></returns>
    public bool CanExecute(object parameter)
    {
        return _canExecute(parameter);
    }

    public void Execute(object parameter)
    {
        _action(parameter);
    }
    public void Refresh()
    {
        CommandManager.InvalidateRequerySuggested();
    }
}

And in xaml:

     <Button
    Command="{Binding ClickCommand}"
    CommandParameter="BtnEdit_Click"/>

Another good option is, to pass a renderTo HTML reference. If it is a string, the element by that id is used. Otherwise you can do:

chart: {
    renderTo: document.getElementById('container')
},

or with jquery:

chart: {
    renderTo: $('#container')[0]
},

I'm not sure if this is what you ask, but you can check gradle version of your project here in android studio:

(left pane must be in project view, not android for this path) app->gradle->wrapper->gradle-wrapper.properties

it has a line like this, indicating the gradle version:

distributionUrl=http\://services.gradle.org/distributions/gradle-1.8-all.zip

There is also a table at the end of this page that shows gradle and gradle plug-in versions supported by each android studio version. (you can check your android studio by checking help->about as you may already know)

I used this to sort a gallery of images where the sort array would be altered by an ajax call. Hopefully it can be useful to someone.

var myArray = ['2', '3', '1'];_x000D_
var elArray = [];_x000D_
_x000D_
$('.imgs').each(function() {_x000D_
    elArray[$(this).data('image-id')] = $(this);_x000D_
});_x000D_
_x000D_
$.each(myArray,function(index,value){_x000D_
   $('#container').append(elArray[value]); _x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>_x000D_
<div id='container'>_x000D_
   <div class="imgs" data-image-id='1'>1</div>_x000D_
   <div class="imgs" data-image-id='2'>2</div>_x000D_
   <div class="imgs" data-image-id='3'>3</div>_x000D_
</div>

You have two choices here. The first is to have two result sets which will set 'Test1' or 'Test2' based on the condition in the WHERE clause, and then UNION them together:

select 
    'Test1', * 
from 
    TABLE 
Where 
    CCC='D' AND DDD='X' AND exists(select ...)
UNION
select 
    'Test2', * 
from 
    TABLE
Where
    CCC<>'D' AND DDD='X' AND exists(select ...)

This might be an issue, because you are going to effectively scan/seek on TABLE twice.

The other solution would be to select from the table once, and set 'Test1' or 'Test2' based on the conditions in TABLE:

select 
    case 
        when CCC='D' AND DDD='X' AND exists(select ...) then 'Test1'
        when CCC<>'D' AND DDD='X' AND exists(select ...) then 'Test2'
    end,
    * 
from 
    TABLE 
Where 
    (CCC='D' AND DDD='X' AND exists(select ...)) or
    (CCC<>'D' AND DDD='X' AND exists(select ...))

The catch here being that you will have to duplicate the filter conditions in the CASE statement and the WHERE statement.

What im doing is, simple overriding join and run method of the Thread:

class RaisingThread(threading.Thread):
  def run(self):
    self._exc = None
    try:
      super().run()
    except Exception as e:
      self._exc = e

  def join(self):
    super().join()
    if self._exc:
      raise self._exc

Used as followed:

def foo():
  time.sleep(2)
  print('hi, from foo!')
  raise Exception('exception from foo')    

t = RaisingThread(target=foo)
t.start()
try:
  t.join()
except Exception as e:
  print(e)

Result:

hi, from foo!
exception from foo!

Using the latest cross-platform Google Maps URLs: Even if google maps app is missing it will open in browser

Example https://www.google.com/maps/dir/?api=1&origin=81.23444,67.0000&destination=80.252059,13.060604

Uri.Builder builder = new Uri.Builder();
builder.scheme("https")
    .authority("www.google.com")
    .appendPath("maps")
    .appendPath("dir")
    .appendPath("")
    .appendQueryParameter("api", "1")
    .appendQueryParameter("destination", 80.00023 + "," + 13.0783);
String url = builder.build().toString();
Log.d("Directions", url);
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

You have to use val() instead of value() and you have missed starting quote id=dbType" should be id="dbType"

Change

selection = $('this').value();

To

selection = $(this).val();

or

selection = this.value;

One would guess that (and my WPF is a little rusty right now) that Margin takes an object and cannot be directly changed.

e.g

MyControl.Margin = new Margin(10,0,0,0);

You shouldn't be looking at what happens around the call that creates the fiber but rather at what happens inside the fiber. Once you are inside the fiber you can program in sync style. For example:

function f1() {
    console.log('wait... ' + new Date);
    sleep(1000);
    console.log('ok... ' + new Date);   
}

function f2() {
    f1();
    f1();
}

Fiber(function() {
    f2();
}).run();

Inside the fiber you call f1, f2 and sleep as if they were sync.

In a typical web application, you will create the Fiber in your HTTP request dispatcher. Once you've done that you can write all your request handling logic in sync style, even if it calls async functions (fs, databases, etc.).

In web application a timer will be the best approach.

Just fyi, in desktop application I use this instead, inside an async method.

... 
Await Task.Run(Sub()
    System.Threading.Thread.Sleep(5000)
End Sub)
...

It work for me, importantly it doesn't freeze entire screen. But again this is on desktop, i try in web application it does freeze.

If one line code is definitely going to happen for you, Python 3.8 introduces assignment expressions affectionately known as “the walrus operator”.

:=

someBoolValue and (num := 20)

The 20 will be assigned to num if the first boolean expression is True. The assignment must be inside parentheses here otherwise you will get a syntax error.

num = 10
someBoolValue = True

someBoolValue and (num := 20)
print(num) # 20

num = 10
someBoolValue = False

someBoolValue and (num := 20)
print(num) # 10

I have taken simple steps to reduce my effort into a process taking O(1) time.

By reducing my inputs to one of two types of socks (white socks for recreation, black socks for work), I only need to determine which of two socks I have in hand. (Technically, since they are never washed together, I have reduced the process to O(0) time.)

Some upfront effort is required to find desirable socks, and to purchase in sufficient quantity as to eliminate need for your existing socks. As I'd done this before my need for black socks, my effort was minimal, but mileage may vary.

Such an upfront effort has been seen many times in very popular and effective code. Examples include #DEFINE'ing pi to several decimals (other examples exist, but that's the one that comes to mind right now).

Instead of just doing this quoted method from https://stackoverflow.com/a/4635440/3787376,

You can do something like this:

// show loading image
$('#loader_img').show();

// main image loaded ?
$('#main_img').on('load', function(){
  // hide/remove the loading image
  $('#loader_img').hide();
});

You assign load event to the image which fires when image has finished loading. Before that, you can show your loader image.

you can use a different jQuery function to make the loading image fade away, then be hidden:

// Show the loading image.
$('#loader_img').show();

// When main image loads:
$('#main_img').on('load', function(){
  // Fade out and hide the loading image.
  $('#loader_img').fadeOut(100); // Time in milliseconds.
});

"Once the opacity reaches 0, the display style property is set to none." http://api.jquery.com/fadeOut/

Or you could not use the jQuery library because there are already simple cross-browser JavaScript methods.

Another tool that I found useful: https://archive.codeplex.com/?p=encodingchecker EXE can be found here

The reason why your image is resizing which is because it is fluid. You have two ways to do it:

1. Either give a fixed dimension to your image using CSS like:

   .carousel-inner > .item > img {
     width:640px;
     height:360px;
   }

2. A second way to can do this:

   .carousel {
     width:640px;
     height:360px;
   }

This is what worked for me, sets focus and shows keyboard also

EditText userNameText = (EditText) findViewById(R.id.textViewUserNameText);
userNameText.setFocusable(true);
userNameText.setFocusableInTouchMode(true);
userNameText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(userNameText, InputMethodManager.SHOW_IMPLICIT);

You can imitate the C idiom in Python.

To read a buffer up to max_size number of bytes, you can do this:

with open(filename, 'rb') as f:
    while True:
        buf = f.read(max_size)
        if not buf:
            break
        process(buf)

Or, a text file line by line:

# warning -- not idiomatic Python! See below...
with open(filename, 'rb') as f:
    while True:
        line = f.readline()
        if not line:
            break
        process(line)

You need to use while True / break construct since there is no eof test in Python other than the lack of bytes returned from a read.

In C, you might have:

while ((ch != '\n') && (ch != EOF)) {
   // read the next ch and add to a buffer
   // ..
}

However, you cannot have this in Python:

 while (line = f.readline()):
     # syntax error

because assignments are not allowed in expressions in Python (although recent versions of Python can mimic this using assignment expressions, see below).

It is certainly more idiomatic in Python to do this:

# THIS IS IDIOMATIC Python. Do this:
with open('somefile') as f:
    for line in f:
        process(line)

Update: Since Python 3.8 you may also use assignment expressions:

 while line := f.readline():
     process(line)

First, note that the function parameter named i and the variable named i in main() are two different variables. I think that doesn't matter that much to the present discussion, but it's important to know.

Second, you use the postincrement operator in fun(). That means the result of the expression is the value before i is incremented; the final value 11 of i is simply discarded, and the function returns 10. The variable i back in main, being a different variable, is assigned the value 10, which you then decrement to get 9.

i had a similar requirement on 1 of the projects where you had to send huge number of emails each day, and the client wanted complete control over html templates for different types of emails.

due to the large number of emails to be sent, performance was a primary concern.

what we came up with was static content in sql server where you save entire html template mark up (along with place holders, like [UserFirstName], [UserLastName] which are replaced with real data at run time) for different types of emails

then we loaded this data in asp.net cache - so we dont read the html templates over and over again - but only when they are actually changed

we gave the client a WYSIWYG editor to modify these templates via a admin web form. whenever updates were made, we reset asp.net cache.

and then we had a seperate table for email logs - where every email to be sent was logged. this table had fields called emailType, emailSent and numberOfTries.

we simply ran a job every 5 minutes for important email types (like new member sign up, forgot password) which need to be sent asap

we ran another job every 15 minutes for less important email types (like promotion email, news email, etc)

this way you dont block your server sending non stop emails and you process mails in batch. once an email is sent you set the emailSent field to 1.

For me, it was the local overrides in Sources -> Overrides. A file gets saved locally whenever you change the styling of a page and chrome uses that file to override the server's css.

With the Python library pandas, you can easily create column names and infer data types from a csv file.

from sqlalchemy import create_engine
import pandas as pd

engine = create_engine('postgresql://user:pass@localhost/db_name')
df = pd.read_csv('/path/to/csv_file')
df.to_sql('pandas_db', engine)

The if_exists parameter can be set to replace or append to an existing table, e.g. df.to_sql('pandas_db', engine, if_exists='replace'). This works for additional input file types as well, docs here and here.

[id^='someId'] will match all ids starting with someId.

[id$='someId'] will match all ids ending with someId.

[id*='someId'] will match all ids containing someId.

If you're looking for the name attribute just substitute id with name.

If you're talking about the tag name of the element I don't believe there is a way using querySelector

You can use the following example:

<table id="purches">
    <thead>
        <tr>
            <th>ID</th>
            <th>Transaction Date</th>
            <th>Category</th>
            <th>Transaction Amount</th>
            <th>Offer</th>
        </tr>
    </thead>

    <!--  <tr th:each="person: ${list}"    >
            <td><li th:each="person: ${list}" th:text="|${person.description}|"></li></td>
            <td><li th:each="person: ${list}" th:text="|${person.price}|"></li></td>
            <td><li th:each="person: ${list}" th:text="|${person.available}|"></li></td>
            <td><li th:each="person: ${list}" th:text="|${person.from}|"></li></td>
            </tr>
    -->

    <tbody id="feedback">
    </tbody>
</table>

JavaScript file:

$.ajax({
    type: "POST",
    contentType: "application/json",
    url: "/search",
    data: JSON.stringify(search),
    dataType: 'json',
    cache: false,
    timeout: 600000,
    success: function (data) {
        //  var json = "<h4>Ajax Response</h4><pre>"  + JSON.stringify(data, null, 4) + "</pre>";
        // $('#feedback').html(json);
        //
        console.log("SUCCESS: ", data);
        //$("#btn-search").prop("disabled", false);

        for (var i = 0; i < data.length; i++) {
            //$("#feedback").append('<tr><td>' + data[i].accountNumber + '</td><td>' + data[i].category + '</td><td>' + data[i].ssn + '</td></tr>');
            $('#feedback').append('<tr><td>' + data[i].accountNumber + '</td><td>' + data[i].category + '</td><td>' + data[i].ssn + '</td><td>' + data[i].ssn + '</td><td>' + data[i].ssn + '</td></tr>');

            alert(data[i].accountNumber)
        }
    },
    error: function (e) {
        var json = "<h4>Ajax Response</h4><pre>" + e.responseText + "</pre>";
        $('#feedback').html(json);

        console.log("ERROR: ", e);
        $("#btn-search").prop("disabled", false);
    }
});

Add an abstraction layer, for example, a YAML file like in this project https://github.com/larytet/dockerfile-generator which looks like

centos7:
    base: centos:centos7
    packager: rpm
    install:
      - $build_essential_centos 
      - rpm-build
    run:
      - $get_release
    env:
      - $environment_vars

A short Python script/make can generate all Dockerfiles from the configuration file.

Use textContent instead of value to set the button text.

Typically the value attribute is used to associate a value with the button when it's submitted as form data.

Note that while it's possible to set the button text with innerHTML, using textContext should be preferred because it's more performant and it can prevent cross-site scripting attacks as its value is not parsed as HTML.

JS:

var b = document.createElement('button');
b.setAttribute('content', 'test content');
b.setAttribute('class', 'btn');  
b.textContent = 'test value';

var wrapper = document.getElementById("divWrapper");
wrapper.appendChild(b);

Produces this in the DOM:

<div id="divWrapper">
    <button content="test content" class="btn">test value</button>
</div>

You can use [ngClass] or [class.classname], both will work the same.
[class.my-class]="step==='step1'"

   OR

[ngClass]="{'my-class': step=='step1'}"

Both will work the same!

If anyone getting below error:

Arithmetic overflow error converting expression to data type int

due to unix timestamp is in bigint (instead of int), you can use this:

SELECT DATEADD(S, CONVERT(int,LEFT(1462924862735870900, 10)), '1970-01-01')
FROM TABLE

Replace the hardcoded timestamp for your actual column with unix-timestamp

The main idea of the solution as above mentioned: find the right path of the .xml file and use it to access the file correctly.

In my case, I installed the opencv in anoconda env, first direct to path of Anoconda, then

• find the path of .xml file by using:

  $ find . -name 'haarcascade_eye.xml' (for example search the haarcascade_eye.xml file in current dir (.))

• Then use the return path:

eye_cascade = cv2.CascadeClassifier(path + 'haarcascade_eye.xml')

Try this

String date = get_pump_data.getString("bond_end_date");
DateFormat format = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
Date datee = (Date)format.parse(date);

Using this Function u can define your won position

setBounds(500, 200, 647, 418);

It is all dependent on how you commit.

For example:

git commit -am "Some message"

will use your ~\.gitconfig username. In other words, if you open that file you should see a line that looks like this:

[user]
    email = [email protected]

That would be the email you want to change. If your doing a pull request through Bitbucket or Github etc. you would be whoever you're logged in as.

OAuth v2 specs indicates:

Access token attributes and the methods used to access protected resources are beyond the scope of this specification and are defined by companion specifications.

My Authorisation Server has a webservice (SOAP) endpoint that allows the Resource Server to know whether the access_token is valid.

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

Firebase listeners fire for both the initial data and any changes.

If you're looking to synchronize the data in a collection, use ChildEventListener. If you're looking to synchronize a single object, use ValueEventListener. Note that in both cases you're not "getting" the data. You're synchronizing it, which means that the callback may be invoked multiple times: for the initial data and whenever the data gets updated.

This is covered in Firebase's quickstart guide for Android. The relevant code and quote:

FirebaseRef.child("message").addValueEventListener(new ValueEventListener() {
  @Override
  public void onDataChange(DataSnapshot snapshot) {
    System.out.println(snapshot.getValue());  //prints "Do you have data? You'll love Firebase."
  }
  @Override
  public void onCancelled(DatabaseError databaseError) {        
  }
});

In the example above, the value event will fire once for the initial state of the data, and then again every time the value of that data changes.

Please spend a few moments to go through that quick start. It shouldn't take more than 15 minutes and it will save you from a lot of head scratching and questions. The Firebase Android Guide is probably a good next destination, for this question specifically: https://firebase.google.com/docs/database/android/read-and-write

In MySQL there is a group_concat function that will return what you're asking for.

SELECT TableA.ID, TableA.Name, group_concat(TableB.SomeColumn)

TableB.TableA_ID = TableA.ID

I've found a very simple solution,

just use the onmouseleave="myfunc()" event than the onmousout="myfunc()" event

In my code it worked!!

Example:

<html>
<head>
<script type="text/javascript">
   function myFunc(){
      document.getElementById('hide_div').style.display = 'none';
   }
   function ShowFunc(){
      document.getElementById('hide_div').style.display = 'block';
   }
</script>
</head>
<body>
<div onmouseleave="myFunc()" style='border:double;width:50%;height:50%;position:absolute;top:25%;left:25%;'>
   Hover mouse here
   <div id='child_div' style='border:solid;width:25%;height:25%;position:absolute;top:10%;left:10%;'>
      CHILD <br/> It doesn't fires if you hover mouse over this child_div
   </div>
</div>
<div id="hide_div" >TEXT</div>
<a href='#' onclick="ShowFunc()">Show "TEXT"</a>
</body>
</html>

Same Example with mouseout function:

<html>
<head>
<script type="text/javascript">
   function myFunc(){
      document.getElementById('hide_div').style.display = 'none';
   }
   function ShowFunc(){
      document.getElementById('hide_div').style.display = 'block';
   }
</script>
</head>
<body>
<div onmouseout="myFunc()" style='border:double;width:50%;height:50%;position:absolute;top:25%;left:25%;'>
   Hover mouse here
   <div id='child_div' style='border:solid;width:25%;height:25%;position:absolute;top:10%;left:10%;'>
      CHILD <br/> It fires if you hover mouse over this child_div
   </div>
</div>
<div id="hide_div">TEXT</div>
<a href='#' onclick="ShowFunc()">Show "TEXT"</a>
</body>
</html>

Hope it helps :)

Using multiple selections: select one pair of line breaks, then use Quick Find All (Alt+F3), or Quick Add Next (Ctrl+D) repeatedly, to select them all; then hit Enter to replace them with single line breaks.

If you see the dollar sign ($) or double dollar sign ($$), and are curious as to what this means in the Prototype framework, here is your answer:

$$('div');
// -> all DIVs in the document.  Same as document.getElementsByTagName('div')!

$$('#contents');
// -> same as $('contents'), only it returns an array anyway (even though IDs must be unique within a document).

$$('li.faux');
// -> all LI elements with class 'faux'

• You can access global keywords without keyword global
• To be able to modify them you need to explicitly state that the keyword is global. Otherwise, the keyword will be declared in local scope.

Example:

words = [...] 

def contains (word): 
    global words             # <- not really needed
    return (word in words) 

def add (word): 
    global words             # must specify that we're working with a global keyword
    if word not in words: 
        words += [word]

2020 answer with Chrome dev tools

To debug any XHR request:

1. Open Chrome DEV tools (F12)
2. Right-click your Ajax url in the console

for a GET request:

• click Open in new tab

for a POST request:

1. click Reveal in Network panel

2. In the Network panel:

   1. click on your request

   2. click on the response tab to see the details

The first method is to prefer. It uses the advanced event registration model[s], which means you can attach multiple handlers to the same element. You can easily access the event object, and the handler can live in any function's scope. Also, it is dynamic, i.e it can be invoked at any time and is especially well-suited for dynamically generated elements. Whether you use jQuery, an other library or the native methods directly does not really matter.

The second method, using inline attributes, needs a lot of global functions (which leads to namespace pollution) and mixes the content/structure (HTML) with the behavior (JavaScript). Do not use that.

Your question about performance or standards can't be easily answered. The two methods are just completely different, and do different things. The first one is mightier, while the second one is despised (considered bad style).

for /f "delims=" %%i in ("%0") do set "curpath=%%~dpi"
echo "%curpath%"

or

echo "%cd%"

The double quotes are needed if the path contains any & characters.

Hammer.js all the way! It handles "transforms" (pinches). http://eightmedia.github.com/hammer.js/

But if you wish to implement it youself, i think that Jeffrey's answer is pretty solid.

Swift 4.2 & 5

// *** Create date ***

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

Here is a quick summary of the segues and an example for each type.

Show - Pushes the destination view controller onto the navigation stack, sliding overtop from right to left, providing a back button to return to the source - or if not embedded in a navigation controller it will be presented modally
Example: Navigating inboxes/folders in Mail

Show Detail - For use in a split view controller, replaces the detail/secondary view controller when in an expanded 2 column interface, otherwise if collapsed to 1 column it will push in a navigation controller
Example: In Messages, tapping a conversation will show the conversation details - replacing the view controller on the right when in a two column layout, or push the conversation when in a single column layout

Present Modally - Presents a view controller in various animated fashions as defined by the Presentation option, covering the previous view controller - most commonly used to present a view controller that animates up from the bottom and covers the entire screen on iPhone, or on iPad it's common to present it as a centered box that darkens the presenting view controller
Example: Selecting Touch ID & Passcode in Settings

Popover Presentation - When run on iPad, the destination appears in a popover, and tapping anywhere outside of this popover will dismiss it, or on iPhone popovers are supported as well but by default it will present the destination modally over the full screen
Example: Tapping the + button in Calendar

Custom - You may implement your own custom segue and have control over its behavior

The deprecated segues are essentially the non-adaptive equivalents of those described above. These segue types were deprecated in iOS 8: Push, Modal, Popover, Replace.

For more info, you may read over the Using Segues documentation which also explains the types of segues and how to use them in a Storyboard. Also check out Session 216 Building Adaptive Apps with UIKit from WWDC 2014. They talked about how you can build adaptive apps using these new Adaptive Segues, and they built a demo project that utilizes these segues.

Make sure their GroupName properties are set to the same name:

<asp:RadioButton GroupName="MeasurementSystem" runat="server" Text="US" />
<asp:RadioButton GroupName="MeasurementSystem" runat="server" Text="Metric" />

I use std::string::compare wrapped in utility method like below:

static bool startsWith(const string& s, const string& prefix) {
    return s.size() >= prefix.size() && s.compare(0, prefix.size(), prefix) == 0;
}

In my case use VS 2013, and It's not support MVC 3 natively (even of you change ./Views/web.config): https://stackoverflow.com/a/28155567/1536197

When I tried to install a new ionic app, I got the same error as follows, I tried many sources and found the mistake made in User Environment and System Environment unnecessarily included the PROXY value. I removed the ```user variables http://host:port PROXY

system Variables http_proxy http://username:password@host:port ```` and now it is working fine without trouble.

[ERROR] Network connectivity error occurred, are you offline?

        If you are behind a firewall and need to configure proxy settings, see: https://ion.link/cli-proxy-docs

        Error: getaddrinfo ENOTFOUND host host:80

If all else fails. Simply try to download the Intel HAXM zip manually, extract and install. check here

Remember this only works for an Intel cpu that supports Intel Virtualization Technology. And you MUST enable virtulization in your bios.

It's a fairly decent and very noticeable improvement to the android emulator if you ask me.

I wish calling SetText were that easy but there are quite a few gotchas that you have to deal with. You have to make sure that the thread you are calling it on is running in the STA. It can sometimes fail with an access denied error then work seconds later without problem - something to do with the COM timing issues in the clipboard. And if your application is accessed over Remote Desktop access to the clipboard is sketchy. We use a centralized method to handle all theses scenarios instead of calling SetText directly.

@Stecy: Here's our centralized code:

The StaHelper class simply executes some arbitrary code on a thread in the Single Thread Apartment (STA) - required by the clipboard.

abstract class StaHelper
{
    readonly ManualResetEvent _complete = new ManualResetEvent( false );    

    public void Go()
    {
        var thread = new Thread( new ThreadStart( DoWork ) )
        {
            IsBackground = true,
        }
        thread.SetApartmentState( ApartmentState.STA );
        thread.Start();
    }

    // Thread entry method
    private void DoWork()
    {
        try
        {
            _complete.Reset();
            Work();
        }
        catch( Exception ex )
        {
            if( DontRetryWorkOnFailed )
                throw;
            else
            {
                try
                {
                    Thread.Sleep( 1000 );
                    Work();
                }
                catch
                {
                    // ex from first exception
                    LogAndShowMessage( ex );
                }
            }
        }
        finally
        {
            _complete.Set();
        }
    }

    public bool DontRetryWorkOnFailed{ get; set; }

    // Implemented in base class to do actual work.
    protected abstract void Work();
}

Then we have a specific class for setting text on the clipboard. Creating a DataObject manually is required in some edge cases on some versions of Windows/.NET. I don't recall the exact scenarios now and it may not be required in .NET 3.5.

class SetClipboardHelper : StaHelper
{
    readonly string _format;
    readonly object _data;

    public SetClipboardHelper( string format, object data )
    {
        _format = format;
        _data = data;
    }

    protected override void Work()
    {
        var obj = new System.Windows.Forms.DataObject(
            _format,
            _data
        );

        Clipboard.SetDataObject( obj, true );
    }
}

Usage looks like this:

new SetClipboardHelper( DataFormats.Text, "See, I'm on the clipboard" ).Go();

In SQL Server 2012+, you can use OFFSET...FETCH:

SELECT
   <column(s)>
FROM
   <table(s)>
ORDER BY
   <sort column(s)>
OFFSET 1 ROWS   -- Skip this number of rows
FETCH NEXT 1 ROWS ONLY;  -- Return this number of rows

Here's a simple example function using python. You can stick in ~/.bashrc
You gotta have a space after the first left curly bracket
The python command needs to be in double quotes to get the variable substitution
Don't forget that semicolon at the end

function count(){ python -c "for num in xrange($1):print num";}

$ count 6
0
1
2
3
4
5
$

After much searching, I finally found something that works with the latest WordPress. Here are the steps to follow:

1. Find your theme's directory, create a folder in the directory for your custom js (custom_js in this example).
2. Put your custom jQuery in a .js file in this directory (jquery_test.js in this example).

3. Make sure your custom jQuery .js looks like this:

   (function($) {
   $(document).ready(function() {
   $('.your-class').addClass('do-my-bidding');
   })
   })(jQuery);
   

4. Go to the theme's directory, open up functions.php

5. Add some code near the top that looks like this:

   //this goes in functions.php near the top
   function my_scripts_method() {
   // register your script location, dependencies and version
      wp_register_script('custom_script',
      get_template_directory_uri() . '/custom_js/jquery_test.js',
      array('jquery'),
      '1.0' );
    // enqueue the script
     wp_enqueue_script('custom_script');
     }
   add_action('wp_enqueue_scripts', 'my_scripts_method');
   

6. Check out your site to make sure it works!

EDIT -- perhaps the best option would be to create a service endpoint that does everything the three requests do. That way you only have to do one request, and all the data is where you need it to be in the response. If you find you are doing the same 3 requests over and over again, you will probably want to go this route. It is often a good design decision to set up a facade service on the server that lumps commonly used smaller server actions together. Just an idea.

one way to do it would be to create a 'sync' object in your click handler before the ajax calls. Something like

var sync = {
   count: 0
}

The sync will be bound to the scope of the success calls automatically (closure). In the success handler, you increment the count, and if it is 3 you can call the other function.

Alternatively, you could do something like

var sync = {
   success1Complete: false,
   ...
   success3Complete: false,
}

when each success is executed, it would change the value in the sync to true. You would have to check the sync to make sure that all three are true before proceeding.

Note the case where one of your xhrs does not return success -- you need to account for that.

Yet another option would be to always call the final function in your success handlers, and have it access the sync option to determine whether to actually do anything. You would need to make sure the sync is in the scope of that function though.

fgets would work for you. here is very good documentation on this :-
http://www.cplusplus.com/reference/cstdio/fgets/

If you don't want to use fgets, following method will work for you :-

int readline(FILE *f, char *buffer, size_t len)
{
   char c; 
   int i;

   memset(buffer, 0, len);

   for (i = 0; i < len; i++)
   {   
      int c = fgetc(f); 

      if (!feof(f)) 
      {   
         if (c == '\r')
            buffer[i] = 0;
         else if (c == '\n')
         {   
            buffer[i] = 0;

            return i+1;
         }   
         else
            buffer[i] = c; 
      }   
      else
      {   
         //fprintf(stderr, "read_line(): recv returned %d\n", c);
         return -1; 
      }   
   }   

   return -1; 
}

Use Column.DefaultCellStyle.Format property or set it in designer

Convert to seconds those strings:

var str1 = '10:20:45';
var str2 = '5:10:10';

str1 =  str1.split(':');
str2 =  str2.split(':');

totalSeconds1 = parseInt(str1[0] * 3600 + str1[1] * 60 + str1[0]);
totalSeconds2 = parseInt(str2[0] * 3600 + str2[1] * 60 + str2[0]);

// compare them

if (totalSeconds1 > totalSeconds2 ) { // etc...

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

You can have many constructors as long as they take in different parameters. But the compiler putting a default constructor in is not called "constructor overriding".

I have catched the same exception and found a InnerException: SocketException. in the svclog trace.

I was facing a similar issue and below line fixed the issue for me.

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
    </dependency>

Edit: I realized that I was using spring boot and the version of the dependency was getting pulled from spring-boot-starter-parent.

Sorry I dont know Java, but I was faced with the same problem tonight, so I wrote this (it's in c#)

public string IncrementString(string inboundString)    {
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(inboundString.ToArray);
bool incrementNext = false;

for (l = -(bytes.Count - 1); l <= 0; l++) {
    incrementNext = false;

    int bIndex = Math.Abs(l);
    int asciiVal = Conversion.Val(bytes(bIndex).ToString);

    asciiVal += 1;

    if (asciiVal > 57 & asciiVal < 65)
        asciiVal = 65;
    if (asciiVal > 90) {
        asciiVal = 48;
        incrementNext = true;
    }

    bytes(bIndex) = System.Text.Encoding.ASCII.GetBytes({ Strings.Chr(asciiVal) })(0);

    if (incrementNext == false)
        break; // TODO: might not be correct. Was : Exit For
}

inboundString = System.Text.Encoding.ASCII.GetString(bytes);

return inboundString;
}

We used something like here, but then taking the average age:

ROUND(avg(CONVERT(int,DATEDIFF(hour,DOB,GETDATE())/8766.0)),0) AS AverageAge

Notice, the ROUND is outside rather than inside. This will allow for the AVG to be more accurate and we ROUND only once. Making it faster too.

$ foo="/some/directory/file"
$ [ ${foo:0:1} == "/" ] && echo 1 || echo 0
1
$ foo="[email protected]:/some/directory/file"
$ [ ${foo:0:1} == "/" ] && echo 1 || echo 0
0

Try including stdint.h or inttypes.h.

You could do it at some point in the past. But now (according to the latest revision of the same standard, which is Candidate Recommendation) you can't .

you can solve it by overriding the Run function of CI_Form_Validation

copy this function in a class which extends CI_Form_Validation .

This function will override the parent class function . Here i added only a extra check which can handle file also

   Note: Download the 3.5 version for Visual Studio 2008 and .NET 3.5, the 4.0 version for Visual Studio 2010 and .NET 4.0.

Then Only, You will able to get the assembly called Microsoft.IdentityModel

Can you change the if condition to this:

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

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

In addition to the accepted answer. You can use a lambda instead of regex:

from bs4 import BeautifulSoup

html = """<p>test python</p>"""

soup = BeautifulSoup(html, "html.parser")

print(soup(text="python"))
print(soup(text=lambda t: "python" in t))

Output:

[]
['test python']

The recent versions of XAMPP for Windows runs PHP 7.x which are NOT compatible with mbcrypt. If you have a package like Laravel that requires mbcrypt, you will need to install an older version of XAMPP. OR, you can run XAMPP with multiple versions of PHP by downloading a PHP package from Windows.PHP.net, installing it in your XAMPP folder, and configuring php.ini and httpd.conf to use the correct version of PHP for your site.

They are user-defined signals, so they aren't triggered by any particular action. You can explicitly send them programmatically:

#include <signal.h>

kill(pid, SIGUSR1);

where pid is the process id of the receiving process. At the receiving end, you can register a signal handler for them:

#include <signal.h>

void my_handler(int signum)
{
    if (signum == SIGUSR1)
    {
        printf("Received SIGUSR1!\n");
    }
}

signal(SIGUSR1, my_handler);

Here is a extension method, this allows coding like the SQL IN command.

public static bool In<T>(this T o, params T[] values)
{
    if (values == null) return false;

    return values.Contains(o);
}
public static bool In<T>(this T o, IEnumerable<T> values)
{
    if (values == null) return false;

    return values.Contains(o);
}

This allows stuff like that:

List<int> ints = new List<int>( new[] {1,5,7});
int i = 5;
bool isIn = i.In(ints);

Or:

int i = 5;
bool isIn = i.In(1,2,3,4,5);

Note that in general, IDE's like Visual Studio will markup a comment in the context of the current language, by selecting the text you wish to turn into a comment, and then using the Ctrl+K Ctrl+C shortcut, or if you are using Resharper / Intelli-J style shortcuts, then Ctrl+/.

Server side Comments:

Razor .cshtml

Like so:

@* Comment goes here *@

.aspx
For those looking for the older .aspx view (and Asp.Net WebForms) server side comment syntax:

<%-- Comment goes here --%>

Client Side Comments

HTML Comment

<!-- Comment goes here -->

Javascript Comment

// One line Comment goes Here
/* Multiline comment
   goes here */

As OP mentions, although not displayed on the browser, client side comments will still be generated for the page / script file on the server and downloaded by the page over HTTP, which unless removed (e.g. minification), will waste I/O, and, since the comment can be viewed by the user by viewing the page source or intercepting the traffic with the browser's Dev Tools or a tool like Fiddler or Wireshark, can also pose a security risk, hence the preference to use server side comments on server generated code (like MVC views or .aspx pages).

NP Problem :-

1. NP problem are such problem that can be solved in non-deterministic polynomial time.
2. Non deterministic algorithm operate in two stage.
3. Non deterministic guessing stage && Non deterministic verification stage.

Type of Np Problem

1. NP complete
2. NP Hard

NP Complete problem :-

1 Decision Problem A is called NP complete if it has following two properties:-

1. It belong to class NP.
2. Every other problem in NP can be transformed to P in polynomial time.

Some Ex :-

• Knapsack problem
• sub set sum problem
• Vertex covering problem

Well, I have tried something I hope it helps ..

They changed the schema a little bit ..

Use the following :

1- Change the AccessDataSource to SQLDataSource in the toolbox.

2- In the drop down menu choose your access database (xxxx.accdb or xxxx.mdb)

3- Next -> Next -> Test Query -> Finish.

Worked for me.

@robertc has it right, but you also need to notice that svg, #container causes the svg to be scaled exponentially for anything but 100% (once for #container and once for svg).

In other words, if I applied 50% h/w to both elements, it's actually 50% of 50%, or .5 * .5, which equals .25, or 25% scale.

One selector works fine when used as @robertc suggests.

svg {
  width:50%;
  height:50%;
}

Inline:

<select 
onchange="var val = this.options[this.selectedIndex].value;
this.form.color[1].style.display=(val=='others')?'block':'none'">

I used to do this

In the head (give the select an ID):

window.onload=function() {
  var sel = document.getElementById('color');
  sel.onchange=function() {
    var val = this.options[this.selectedIndex].value;
    if (val == 'others') {
      var newOption = prompt('Your own color','');
      if (newOption) {
        this.options[this.options.length-1].text = newOption;
        this.options[this.options.length-1].value = newOption;
        this.options[this.options.length] = new Option('other','other');
      }
    }
  }
}

You don't have to necessarily provide name and Qualifier. If you set a name, that's the name with which the bean is registered in the context. If you don't provide a name for your service it will be registered as uncapitalized non-qualified class name based on BeanNameGenerator. So in your case the Implementation will be registered as employeeServiceImpl. So if you try to autowire with that name, it should resolve directly.

private EmployeeService employeeServiceImpl;

@RequestMapping("/employee")
public String employee() {
    this.employeeService.fetchAll();
    return "employee";
}

@Autowired(required = true)
public void setEmployeeService(EmployeeService employeeServiceImpl) {
    this.employeeServiceImpl = employeeServiceImpl;
}

@Qualifier is used in case if there are more than one bean exists of same type and you want to autowire different implementation beans for various purposes.

git checkout -f

This is suffice for your question. Only thing is, once its done, its done. There is no undo.

My answer to this is the same as in an answer to your earlier question. For a probability density function, the integral over the entire space is 1. Dividing by the sum will not give you the correct density. To get the right density, you must divide by the area. To illustrate my point, try the following example.

[f, x] = hist(randn(10000, 1), 50); % Create histogram from a normal distribution.
g = 1 / sqrt(2 * pi) * exp(-0.5 * x .^ 2); % pdf of the normal distribution

% METHOD 1: DIVIDE BY SUM
figure(1)
bar(x, f / sum(f)); hold on
plot(x, g, 'r'); hold off

% METHOD 2: DIVIDE BY AREA
figure(2)
bar(x, f / trapz(x, f)); hold on
plot(x, g, 'r'); hold off

You can see for yourself which method agrees with the correct answer (red curve).

Another method (more straightforward than method 2) to normalize the histogram is to divide by sum(f * dx) which expresses the integral of the probability density function, i.e.

% METHOD 3: DIVIDE BY AREA USING sum()
figure(3)
dx = diff(x(1:2))
bar(x, f / sum(f * dx)); hold on
plot(x, g, 'r'); hold off

if you just want to set the style attribute use

$('.handle').attr('style','left: 300px');

Or you can use css method of jQuery to set only one css style property

$('.handle').css('left', '300px');

OR same as key value

$('.handle').css({'left': '300px', position});

I believe tuple() takes a list as an argument For example,

tuple([1,2,3]) # returns (1,2,3)

see what happens if you wrap your array with brackets

select top 0 *
into #mytemptable
from myrealtable

Simple way:

System.out.println(java.lang.String.class.getResource(String.class.getSimpleName()+".class"));

Out Example:

jar:file:/D:/Java/jdk1.8/jre/lib/rt.jar!/java/lang/String.class

Or

String obj = "simple test"; System.out.println(obj.getClass().getResource(obj.getClass().getSimpleName()+".class"));

Out Example:

jar:file:/D:/Java/jdk1.8/jre/lib/rt.jar!/java/lang/String.class

maybe not the fastest one:

//for example there is an integer with the value of 5:
int i = 5;

//getting the char '5' out of it:
char c = String.format("%s",i).charAt(0); 

Well, you can use Expression.AndAlso / OrElse etc to combine logical expressions, but the problem is the parameters; are you working with the same ParameterExpression in expr1 and expr2? If so, it is easier:

var body = Expression.AndAlso(expr1.Body, expr2.Body);
var lambda = Expression.Lambda<Func<T,bool>>(body, expr1.Parameters[0]);

This also works well to negate a single operation:

static Expression<Func<T, bool>> Not<T>(
    this Expression<Func<T, bool>> expr)
{
    return Expression.Lambda<Func<T, bool>>(
        Expression.Not(expr.Body), expr.Parameters[0]);
}

Otherwise, depending on the LINQ provider, you might be able to combine them with Invoke:

// OrElse is very similar...
static Expression<Func<T, bool>> AndAlso<T>(
    this Expression<Func<T, bool>> left,
    Expression<Func<T, bool>> right)
{
    var param = Expression.Parameter(typeof(T), "x");
    var body = Expression.AndAlso(
            Expression.Invoke(left, param),
            Expression.Invoke(right, param)
        );
    var lambda = Expression.Lambda<Func<T, bool>>(body, param);
    return lambda;
}

Somewhere, I have got some code that re-writes an expression-tree replacing nodes to remove the need for Invoke, but it is quite lengthy (and I can't remember where I left it...)

Generalized version that picks the simplest route:

static Expression<Func<T, bool>> AndAlso<T>(
    this Expression<Func<T, bool>> expr1,
    Expression<Func<T, bool>> expr2)
{
    // need to detect whether they use the same
    // parameter instance; if not, they need fixing
    ParameterExpression param = expr1.Parameters[0];
    if (ReferenceEquals(param, expr2.Parameters[0]))
    {
        // simple version
        return Expression.Lambda<Func<T, bool>>(
            Expression.AndAlso(expr1.Body, expr2.Body), param);
    }
    // otherwise, keep expr1 "as is" and invoke expr2
    return Expression.Lambda<Func<T, bool>>(
        Expression.AndAlso(
            expr1.Body,
            Expression.Invoke(expr2, param)), param);
}

Starting from .NET 4.0, there is the ExpressionVisitor class which allows you to build expressions that are EF safe.

    public static Expression<Func<T, bool>> AndAlso<T>(
        this Expression<Func<T, bool>> expr1,
        Expression<Func<T, bool>> expr2)
    {
        var parameter = Expression.Parameter(typeof (T));

        var leftVisitor = new ReplaceExpressionVisitor(expr1.Parameters[0], parameter);
        var left = leftVisitor.Visit(expr1.Body);

        var rightVisitor = new ReplaceExpressionVisitor(expr2.Parameters[0], parameter);
        var right = rightVisitor.Visit(expr2.Body);

        return Expression.Lambda<Func<T, bool>>(
            Expression.AndAlso(left, right), parameter);
    }



    private class ReplaceExpressionVisitor
        : ExpressionVisitor
    {
        private readonly Expression _oldValue;
        private readonly Expression _newValue;

        public ReplaceExpressionVisitor(Expression oldValue, Expression newValue)
        {
            _oldValue = oldValue;
            _newValue = newValue;
        }

        public override Expression Visit(Expression node)
        {
            if (node == _oldValue)
                return _newValue;
            return base.Visit(node);
        }
    }

while IFS='=' read -r name value ; do
    # Print line if found variable
    sed -n '/${'"${name}"'}/p' docker-compose.yml
    # Replace variable with value. 
    sed -i 's|${'"${name}"'}|'"${value}"'|' docker-compose.yml
done < <(env)

Note: Variable name or value should not contain "|", because it is used as a delimiter.

I started working on this problem a long time ago, trying to write my own binary to decimal converter function. I don't actually know how to convert decimal to binary though! I just revisited it today and figured it out and this is what I came up with. I'm not sure if this is what you need, but here it is:

def __degree(number):
    power = 1

    while number % (10**power) != number:
        power += 1

    return power

def __getDigits(number):
    digits = []
    degree = __degree(number)

    for x in range(0, degree):
        digits.append(int(((number % (10**(degree-x))) - (number % (10**(degree-x-1)))) / (10**(degree-x-1))))
    return digits

def binaryToDecimal(number):
    list = __getDigits(number)
    decimalValue = 0
    for x in range(0, len(list)):
        if (list[x] is 1):
            decimalValue += 2**(len(list) - x - 1)
    return decimalValue

Again, I'm still learning Python just on my own, hopefully this helps. The first function determines how many digits there are, the second function actually figures out they are and returns them in a list, and the third function is the only one you actually need to call, and it calculates the decimal value. If your teacher actually wanted you to write your own converter, this works, I haven't tested it with every number, but it seems to work perfectly! I'm sure you'll all find the bugs for me! So anyway, I just called it like:

binaryNum = int(input("Enter a binary number: "))

print(binaryToDecimal(binaryNum))

This prints out the correct result. Cheers!

Open command prompt, type "systeminfo" and press enter. Your system may take few mins to get the information. In the result page you will find an entry as "System Installation Date". That is the date of windows installation. This process works in XP ,Win7 and also on win8.

Pretty basic but works:

function dynamicHeight() {
    var height = jQuery('').height();
    jQuery('.edito-wrapper').css('height', editoHeight);
}
editoHeightSize();

jQuery(window).resize(function () {
    editoHeightSize();
});

Reference jquery.validate.js and jquery-1.2.6.js. Add a startDate class to your start date textbox. Add an endDate class to your end date textbox.

Add this script block to your page:-

<script type="text/javascript">
    $(document).ready(function() {
        $.validator.addMethod("endDate", function(value, element) {
            var startDate = $('.startDate').val();
            return Date.parse(startDate) <= Date.parse(value) || value == "";
        }, "* End date must be after start date");
        $('#formId').validate();
    });
</script>

Hope this helps :-)
