There is a simplest and quick way to import a Gradle project into Eclipse. Just download the Gradle plugin for Eclipse from here.
https://marketplace.eclipse.org/content/gradle-integration-eclipse-0

And then from import select Gradle and your project would be imported. Then you have to click on Build Model to run it.

EDIT
Above link for Gradle plugin is no more valid. You can use the link as mentioned in the comment by @vikramvi

There is no VBA built in functionality for removing duplicates from an array, however you could use the next function:

Function RemoveDuplicates(MyArray As Variant) As Variant
    With CreateObject("scripting.dictionary")
        For Each item In MyArray
            c00 = .Item(item)
        Next
        sn = .keys ' the array .keys contains all unique keys
        MsgBox Join(.keys, vbLf) ' you can join the array into a string
        RemoveDuplicates = .keys ' return an array without duplicates
    End With
End Function

var arr = [];
var len = oFullResponse.results.length;
for (var i = 0; i < len; i++) {
    arr.push({
        key: oFullResponse.results[i].label,
        sortable: true,
        resizeable: true
    });
}

As David notes, his suggestion does not actually fulfill the OP's request, which was an email with subject and message. It doesn't work because most, maybe all, combinations of browsers plus e-mail clients do not accept the subject and body attributes of the mailto: URI when supplied as a <form>'s action.

But here's a working example:

HTML (with Bootstrap styles):

<p><input id="subject" type="text" placeholder="type your subject here" 
    class="form-control"></p>
<p><input id="message" type="text" placeholder="type your message here" 
    class="form-control"></p>
<p><a id="mail-link" class="btn btn-primary">Create email</a></p>

JavaScript (with jQuery):

<script type="text/javascript">
    function loadEvents() {
        var mailString;
        function updateMailString() {
            mailString = '?subject=' + encodeURIComponent($('#subject').val())
                + '&body=' + encodeURIComponent($('#message').val());
            $('#mail-link').attr('href',  'mailto:[email protected]' + mailString);
        }
        $( "#subject" ).focusout(function() { updateMailString(); });
        $( "#message" ).focusout(function() { updateMailString(); });
        updateMailString();
    }
</script>

Notes:

• The <form> element with associated action attribute is not used.
• The <input> element of type button is also not used.
  • <a> styled as a button (here using Bootstrap) replaces <input type="button">
  • focusout() with updateMailString() is necessary because the <a> tag's href attribute does not automatically update when the input fields' values change.
  • updateMailString() is also called when document is loaded in case the input fields are prepopulated.
• Also encodeURIComponent() is used to get characters such as the quotation mark (") across to Outlook.

In this approach, the mailto: URI is supplied (with subject and body attributes) in an a element's href tag. This works in all combinations of browsers and e-mail clients I have tested, which are recent (2015) versions of:

• Browsers: Firefox/Win&OSX, Chrome/Win&OSX, IE/Win, Safari/OSX&iOS, Opera/OSX
• E-mail clients: Outlook/Win, Mail.app/OSX&iOS, Sparrow/OSX

Bonus tip: In my use cases, I add some contextual text to the e-mail body. More often than not, I want that text to contain line breaks. %0D%0A (carriage return and linefeed) works in my tests.

Note: Posted this answer because OP later stated in comments that they need to select the last two elements, not just the second to last one.

The :nth-child CSS3 selector is in fact more capable than you ever imagined!

For example, this will select the last 2 elements of #container:

#container :nth-last-child(-n+2) {}

But this is just the beginning of a beautiful friendship.

• :nth-child Browser Support

#container :nth-last-child(-n+2) {
  background-color: cyan;
}

<div id="container">
 <div>a</div>
 <div>b</div>
 <div>SELECT THIS</div>
 <div>SELECT THIS</div>
</div>

You can use

SET STATISTICS TIME { ON | OFF }

Displays the number of milliseconds required to parse, compile, and execute each statement

When SET STATISTICS TIME is ON, the time statistics for a statement are displayed. When OFF, the time statistics are not displayed

USE AdventureWorks2012;  
GO         
SET STATISTICS TIME ON;  
GO  
SELECT ProductID, StartDate, EndDate, StandardCost   
FROM Production.ProductCostHistory  
WHERE StandardCost < 500.00;  
GO  
SET STATISTICS TIME OFF;  
GO  

When I want to develop insensitive case searchs, I always convert every string to lower case before do comparasion

function insertHtml(id, html)  
{  
   var ele = document.getElementById(id);  
   ele.innerHTML = html;  
   var codes = ele.getElementsByTagName("script");   
   for(var i=0;i<codes.length;i++)  
   {  
       eval(codes[i].text);  
   }  
}  

It works in Chrome in my project

Why have apples when you can have oranges?

Seriously guys and gals - if your collection is large, read and written to gazillions of times, and you're paying for CPU cycles, then the choice of the collection is relevant ONLY if you NEED it to perform better. However, in most cases, this doesn't really matter - a few milliseconds here and there go unnoticed in human terms. If it really mattered that much, why aren't you writing code in assembler or C? [cue another discussion]. So the point is if you're happy using whatever collection you chose, and it solves your problem [even if it's not specifically the best type of collection for the task] knock yourself out. The software is malleable. Optimise your code where necessary. Uncle Bob says Premature Optimisation is the root of all evil. Uncle Bob says so

This has saved my life: https://medium.com/@CarrieGuss/how-to-recover-from-a-git-hard-reset-b830b5e3f60c

Basically you need to run:

for blob in $(git fsck --lost-found | awk ‘$2 == “blob” { print $3 }’); do git cat-file -p $blob > $blob.txt; done

Then manually going through the pain to re-organise your files to the correct structure.

Takeaway: Never use git reset --hard if you dont completely 100% understand how it works, best not to use it.

Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.

The query with the LIKE keyword showed a clustered index scan.

The CONTAINS also had a clustered index scan with additional operators for the full text match and a merge join.

Speaking with regard to the spec (http://www.w3.org/TR/CSS2/zindex.html), since a.someSelector is positioned it creates a new stacking context that its children can't break out of. Leave a.someSelector unpositioned and then child a.someSelector:after may be positioned in the same context as a.someSelector.

I created a extention to response to this you could includ it in your projects, I think this return the most case when you search for duplicates in List or Linq.

Example:

//Dummy class to compare in list
public class Person
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Surname { get; set; }
    public Person(int id, string name, string surname)
    {
        this.Id = id;
        this.Name = name;
        this.Surname = surname;
    }
}


//The extention static class
public static class Extention
{
    public static IEnumerable<T> getMoreThanOnceRepeated<T>(this IEnumerable<T> extList, Func<T, object> groupProps) where T : class
    { //Return only the second and next reptition
        return extList
            .GroupBy(groupProps)
            .SelectMany(z => z.Skip(1)); //Skip the first occur and return all the others that repeats
    }
    public static IEnumerable<T> getAllRepeated<T>(this IEnumerable<T> extList, Func<T, object> groupProps) where T : class
    {
        //Get All the lines that has repeating
        return extList
            .GroupBy(groupProps)
            .Where(z => z.Count() > 1) //Filter only the distinct one
            .SelectMany(z => z);//All in where has to be retuned
    }
}

//how to use it:
void DuplicateExample()
{
    //Populate List
    List<Person> PersonsLst = new List<Person>(){
    new Person(1,"Ricardo","Figueiredo"), //fist Duplicate to the example
    new Person(2,"Ana","Figueiredo"),
    new Person(3,"Ricardo","Figueiredo"),//second Duplicate to the example
    new Person(4,"Margarida","Figueiredo"),
    new Person(5,"Ricardo","Figueiredo")//third Duplicate to the example
    };

    Console.WriteLine("All:");
    PersonsLst.ForEach(z => Console.WriteLine("{0} -> {1} {2}", z.Id, z.Name, z.Surname));
    /* OUTPUT:
        All:
        1 -> Ricardo Figueiredo
        2 -> Ana Figueiredo
        3 -> Ricardo Figueiredo
        4 -> Margarida Figueiredo
        5 -> Ricardo Figueiredo
        */

    Console.WriteLine("All lines with repeated data");
    PersonsLst.getAllRepeated(z => new { z.Name, z.Surname })
        .ToList()
        .ForEach(z => Console.WriteLine("{0} -> {1} {2}", z.Id, z.Name, z.Surname));
    /* OUTPUT:
        All lines with repeated data
        1 -> Ricardo Figueiredo
        3 -> Ricardo Figueiredo
        5 -> Ricardo Figueiredo
        */
    Console.WriteLine("Only Repeated more than once");
    PersonsLst.getMoreThanOnceRepeated(z => new { z.Name, z.Surname })
        .ToList()
        .ForEach(z => Console.WriteLine("{0} -> {1} {2}", z.Id, z.Name, z.Surname));
    /* OUTPUT:
        Only Repeated more than once
        3 -> Ricardo Figueiredo
        5 -> Ricardo Figueiredo
        */
}

1. remove unwanted dependencies from package.json
2. npm i

"npm i" will not only install missing deps, it updates node_modules to match the package.json

One liners for saving/reading to/from String, using java.nio.

import java.nio.file.{Paths, Files, StandardOpenOption}
import java.nio.charset.{StandardCharsets}
import scala.collection.JavaConverters._

def write(filePath:String, contents:String) = {
  Files.write(Paths.get(filePath), contents.getBytes(StandardCharsets.UTF_8), StandardOpenOption.CREATE)
}

def read(filePath:String):String = {
  Files.readAllLines(Paths.get(filePath), StandardCharsets.UTF_8).asScala.mkString
}

This isn't suitable for large files, but will do the job.

Some links:

java.nio.file.Files.write
java.lang.String.getBytes
scala.collection.JavaConverters
scala.collection.immutable.List.mkString

As a side note, you can include the separators while splitting the string in Go. To do so, use strings.SplitAfter as in the example below.

package main

import (
    "fmt"
    "strings"
)

func main() {
    fmt.Printf("%q\n", strings.SplitAfter("z,o,r,r,o", ","))
}

>>> format(3735928559, 'x')
'deadbeef'

DO NOT run php artisan migrate:fresh that's gonna drop all the tables

There is also another way of getting thread id. While creating threads with

int pthread_create(pthread_t * thread, const pthread_attr_t * attr, void * (*start_routine)(void *), void *arg);

function call; the first parameter pthread_t * thread is actually a thread id (that is an unsigned long int defined in bits/pthreadtypes.h). Also, the last argument void *arg is the argument that is passed to void * (*start_routine) function to be threaded.

You can create a structure to pass multiple arguments and send a pointer to a structure.

typedef struct thread_info {
    pthread_t thread;
    //...
} thread_info;
//...
tinfo = malloc(sizeof(thread_info) * NUMBER_OF_THREADS);
//...
pthread_create (&tinfo[i].thread, NULL, handler, (void*)&tinfo[i]);
//...
void *handler(void *targs) {
    thread_info *tinfo = targs;
    // here you get the thread id with tinfo->thread
}

That is very odd.

I went through ItemNotFoundException's base classes and tested the following multiple catches to see what would catch it:

try {
  remove-item C:\nonexistent\file.txt -erroraction stop
}
catch [System.Management.Automation.ItemNotFoundException] {
  write-host 'ItemNotFound'
}
catch [System.Management.Automation.SessionStateException] {
  write-host 'SessionState'
}
catch [System.Management.Automation.RuntimeException] {
  write-host 'RuntimeException'
}
catch [System.SystemException] {
  write-host 'SystemException'
}
catch [System.Exception] {
  write-host 'Exception'
}
catch {
  write-host 'well, darn'
}

As it turns out, the output was 'RuntimeException'. I also tried it with a different exception CommandNotFoundException:

try {
  do-nonexistent-command
}
catch [System.Management.Automation.CommandNotFoundException] {
  write-host 'CommandNotFoundException'
}
catch {
  write-host 'well, darn'
}

That output 'CommandNotFoundException' correctly.

I vaguely remember reading elsewhere (though I couldn't find it again) of problems with this. In such cases where exception filtering didn't work correctly, they would catch the closest Type they could and then use a switch. The following just catches Exception instead of RuntimeException, but is the switch equivalent of my first example that checks all base types of ItemNotFoundException:

try {
  Remove-Item C:\nonexistent\file.txt -ErrorAction Stop
}
catch [System.Exception] {
  switch($_.Exception.GetType().FullName) {
    'System.Management.Automation.ItemNotFoundException' {
      write-host 'ItemNotFound'
    }
    'System.Management.Automation.SessionStateException' {
      write-host 'SessionState'
    }
    'System.Management.Automation.RuntimeException' {
      write-host 'RuntimeException'
    }
    'System.SystemException' {
      write-host 'SystemException'
    }
    'System.Exception' {
      write-host 'Exception'
    }
    default {'well, darn'}
  }
}

This writes 'ItemNotFound', as it should.

I had a same problem with scrolling in chrome. So i removed this lines of codes from my style file.

html{height:100%;}
body{height:100%;}

Now i can play with scroll and it works:

var pos = 500;
$("html,body").animate({ scrollTop: pos }, "slow");

Your CSS is actually setting the rest of the document to not show overflow therefore the document itself isn't scrolling. The easiest fix for this is bind the event to the thing that is scrolling, which in your case is div#page.

So its easy as changing:

$(document).scroll(function() {  // OR  $(window).scroll(function() {
    didScroll = true;
});

to

$('div#page').scroll(function() {
    didScroll = true;
});

You should know that CPython doesn't really support multithreading (it does, but not optimal) because of the Global Interpreter Lock. It also has no Optimisation mechanisms for recursion, and has many other limitations that other implementations and libraries try to fill.

You should take a look at this page on the python wiki.

Look at the code snippets on this page, it'll give you a good idea of what an interpreter is.

you can simply do this..

 <img src={"http://img.example.com/test/" + this.props.url +"/1.jpg"}/>

You can use the CSS style white-space:

white-space: nowrap;

You can use the iprof library:

https://gitlab.com/Neurochrom/iprof

https://github.com/Neurochrom/iprof

It's cross-platform and allows you not to measure performance of your application also in real-time. You can even couple it with a live graph. Full disclaimer: I am the author.

The problem is that buttonClickedEvent is a member function and you need a pointer to member in order to invoke it.

Try this:

void (MyClass::*func)(int);
func = &MyClass::buttonClickedEvent;

And then when you invoke it, you need an object of type MyClass to do so, for example this:

(this->*func)(<argument>);

http://www.codeguru.com/cpp/cpp/article.php/c17401/C-Tutorial-PointertoMember-Function.htm

When TOP is used with INSERT, UPDATE, MERGE, or DELETE, the referenced rows are not arranged in any order and the ORDER BY clause can not be directly specified in these statements. If you need to use TOP to insert, delete, or modify rows in a meaningful chronological order, you must use TOP together with an ORDER BY clause that is specified in a subselect statement.

TOP cannot be used in an UPDATE and DELETE statements on partitioned views.

TOP cannot be combined with OFFSET and FETCH in the same query expression (in the same query scope). For more information, see http://technet.microsoft.com/en-us/library/ms189463.aspx

Thanks. Opening the URL connection by passing the Proxy as suggested by NickDK works fine.

//Proxy instance, proxy ip = 10.0.0.1 with port 8080
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("10.0.0.1", 8080));
conn = new URL(urlString).openConnection(proxy);

System properties however doesn't work as I had mentioned earlier.

Thanks again.

Try:

CREATE TABLE foo SELECT * FROM bar LIMIT 0

Or:

CREATE TABLE foo SELECT * FROM bar WHERE 1=0

Service vs Factory

The difference between factory and service is just like the difference between a function and an object

Factory Provider

• Gives us the function's return value ie. You just create an object, add properties to it, then return that same object.When you pass this service into your controller, those properties on the object will now be available in that controller through your factory. (Hypothetical Scenario)

• Singleton and will only be created once

• Reusable components

• Factory are a great way for communicating between controllers like sharing data.

• Can use other dependencies

• Usually used when the service instance requires complex creation logic

• Cannot be injected in .config() function.

• Used for non configurable services

• If you're using an object, you could use the factory provider.

• Syntax: module.factory('factoryName', function);

Service Provider

• Gives us the instance of a function (object)- You just instantiated with the ‘new’ keyword and you’ll add properties to ‘this’ and the service will return ‘this’.When you pass the service into your controller, those properties on ‘this’ will now be available on that controller through your service. (Hypothetical Scenario)

• Singleton and will only be created once

• Reusable components

• Services are used for communication between controllers to share data

• You can add properties and functions to a service object by using the this keyword

• Dependencies are injected as constructor arguments

• Used for simple creation logic

• Cannot be injected in .config() function.

• If you're using a class you could use the service provider

• Syntax: module.service(‘serviceName’, function);

Sample Demo

In below example I have define MyService and MyFactory. Note how in .service I have created the service methods using this.methodname. In .factory I have created a factory object and assigned the methods to it.

AngularJS .service

module.service('MyService', function() {

    this.method1 = function() {
            //..method1 logic
        }

    this.method2 = function() {
            //..method2 logic
        }
});

AngularJS .factory

module.factory('MyFactory', function() {

    var factory = {}; 

    factory.method1 = function() {
            //..method1 logic
        }

    factory.method2 = function() {
            //..method2 logic
        }

    return factory;
});

Also Take a look at this beautiful stuffs

Confused about service vs factory

AngularJS Factory, Service and Provider

Angular.js: service vs provider vs factory?

No, you need to handle every statement separately..

UPDATE table1
 Statement1;
 UPDATE table 1
 Statement2;

And so on

If you want the year from a (unknown) datetime-object:

tijd = datetime.datetime(9999, 12, 31, 23, 59, 59)

>>> tijd.timetuple()
time.struct_time(tm_year=9999, tm_mon=12, tm_mday=31, tm_hour=23, tm_min=59, tm_sec=59, tm_wday=4, tm_yday=365, tm_isdst=-1)
>>> tijd.timetuple().tm_year
9999

Also, even at the lastest versions of pandas if the column is object type you would have to convert into float first, something like:

df['column_name'].astype(np.float).astype("Int32")

NB: You have to go through numpy float first and then to nullable Int32, for some reason.

The size of the int if it's 32 or 64 depends on your variable, be aware you may loose some precision if your numbers are to big for the format.

Convert string to ascii values.

   String test = "ABCD";

   for ( int i = 0; i < test.length(); ++i ) {
   char c = test.charAt( i );
   int j = (int) c;
   System.out.println(j);
   }

I recommend WinDirStat.

I frequently use WinDirStat to create screen shots for user documentation of open folders and their contents.

It even uses the correct icons for Windows registered file types.

All I would say is missing is an option to display the files without their icons. I can live without it personally, since I am usually pasting the image into a paint program or Visio to edit it, but it would still be a useful feature.

You can Use This One To get the selected ListItme Name ::

String selectedItem = ((ListBoxItem)ListBox.SelectedItem).Name.ToString();

Make sure that Your each ListBoxItem have a Name property

Not sure if this will help somebody else out or not but this was the key part to fix my problem in user "Tom Hawtin - tacklin"'s answer above:

synchronized (lock) {
    makeWakeupNeeded();
    lock.notifyAll();
}

Just the fact that the "lock" is passed as an argument in synchronized() and it is also used in "lock".notifyAll();

Once I made it in those 2 places I got it working

I've been using something like this. Just set up a simple HTML page with an textinput. Make sure that the textinput always has focus. When you scan a barcode with your barcode scanner you will receive the code and after that a 'enter'. Realy simple then; just capture the incoming keystrokes and when the 'enter' comes in you can use AJAX to handle your code.

Basing on existing answers and some suggestions, I've created this one:

String.prototype.removeAccents = function() {

    var removalMap = {

    var str = this;

    for(var latin in removalMap) {
      var nonLatin = removalMap[latin];
      str = str.replace(nonLatin , latin);
    }

    return str;
}

It uses real chars instead of unicode list and works well.

You can use it like

"aaa".removeAccents(); // returns "aaa"

You can easily convert this function to not be string prototype. However, as I'm fan of using string prototype in such cases, you'll have to do it yourself.

Another difference is when async function returns just Task instead of Task<T> then you cannot use

GetFooAsync(...).Result;

Whereas

GetFooAsync(...).GetAwaiter().GetResult();

still works.

I know the example code in the question is for the case Task<T>, however the question is asked generally.

In addition to the other answers.

If you control the structure of the DataTable there is a shortcut for adding rows:

// Assume you have a data table defined as in your example named dt dt.Rows.Add("Name", "Marks");

The DataRowCollection.Add() method has an overload that takes a param array of objects. This method lets you pass as many values as needed, but they must be in the same order as the columns are defined in the table.

So while this is a convenient way to add row data, it can be risky to use. If the table structure changes your code will fail.

Well, both will clean. That means they'll remove the target folder. The real question is what's the difference between package and install?

package will compile your code and also package it. For example, if your pom says the project is a jar, it will create a jar for you when you package it and put it somewhere in the target directory (by default).

install will compile and package, but it will also put the package in your local repository. This will make it so other projects can refer to it and grab it from your local repository.

Documentation

Just in case there's anyone here using netbeans and has the same problem, all you have to do is

• Right click on TestLibraries
• Click on Add Library
• Select JUnit and click add library
• Repeat the process but this time click on Hamcrest and the click add library

This should solve the problem

A query string is an array of parameters sent to a web page.

This url: http://page.asp?x=1&y=hello

Request.QueryString[0] is the same as 
Request.QueryString["x"] and holds a string value "1"

Request.QueryString[1] is the same as 
Request.QueryString["y"] and holds a string value "hello"

Big warning on several of the solutions (and your own test) :

When you do : anything | xargs something

xargs will try to fit "as many arguments as possible" after "something", but then you may end up with multiple invocations of "something".

So your attempt: find ... | xargs tar czvf file.tgz may end up overwriting "file.tgz" at each invocation of "tar" by xargs, and you end up with only the last invocation! (the chosen solution uses a GNU -T special parameter to avoid the problem, but not everyone has that GNU tar available)

You could do instead:

find . -type f -print0 | xargs -0 tar -rvf backup.tar
gzip backup.tar

Proof of the problem on cygwin:

$ mkdir test
$ cd test
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs touch 
    # create the files
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar czvf archive.tgz
    # will invoke tar several time as it can'f fit 10000 long filenames into 1
$ tar tzvf archive.tgz | wc -l
60
    # in my own machine, I end up with only the 60 last filenames, 
    # as the last invocation of tar by xargs overwrote the previous one(s)

# proper way to invoke tar: with -r  (which append to an existing tar file, whereas c would overwrite it)
# caveat: you can't have it compressed (you can't add to a compressed archive)
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar rvf archive.tar #-r, and without z
$ gzip archive.tar
$ tar tzvf archive.tar.gz | wc -l
10000 
  # we have all our files, despite xargs making several invocations of the tar command

 

Note: that behavior of xargs is a well know diccifulty, and it is also why, when someone wants to do :

find .... | xargs grep "regex"

they intead have to write it:

find ..... | xargs grep "regex" /dev/null

That way, even if the last invocation of grep by xargs appends only 1 filename, grep sees at least 2 filenames (as each time it has: /dev/null, where it won't find anything, and the filename(s) appended by xargs after it) and thus will always display the file names when something maches "regex". Otherwise you may end up with the last results showing matches without a filename in front.

If you are using ndk r10c or later, simply add APP_STL=c++_static to Application.mk

this works fine for me..

$host="127.0.0.1";
$output=shell_exec('ping -n 1 '.$host);

echo "<pre>$output</pre>"; //for viewing the ping result, if not need it just remove it

if (strpos($output, 'out') !== false) {
    echo "Dead";
}
    elseif(strpos($output, 'expired') !== false)
{
    echo "Network Error";
}
    elseif(strpos($output, 'data') !== false)
{
    echo "Alive";
}
else
{
    echo "Unknown Error";
}

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

you can use

var FirstString = YourString.Split().First();

to split string .

1st try to create new keystore....then open taskArtifacts.bin with notepad and look for password that you just given....you will able to figure out words near to password that you just given then search for these words near to your password in same file....you will able to figure out the password.....:)

what I did is created simple binding to hide view when keyboard is visible. Solution is based on current AndroidX implementation for WindowInsetsCompat which is still in beta (androidx core 1.5) - source

private fun isKeyboardVisible(insets: WindowInsets): Boolean {
    val insetsCompat = WindowInsetsCompat.toWindowInsetsCompat(insets)
    val systemWindow = insetsCompat.systemWindowInsets
    val rootStable = insetsCompat.stableInsets
    if (systemWindow.bottom > rootStable.bottom) {
        // This handles the adjustResize case on < API 30, since
        // systemWindow.bottom is probably going to be the IME
        return true
    }
    return false
}

@BindingAdapter("goneWhenKeyboardVisible")
fun View.goneWhenKeyboardVisible(enabled: Boolean) {
    if (enabled) {
        setOnApplyWindowInsetsListener { view, insets ->
            visibility = if (isKeyboardVisible(insets)) GONE else VISIBLE
            insets
        }
    } else {
        setOnApplyWindowInsetsListener(null)
        visibility = VISIBLE
    }
}

usage:

<FrameLayout
                android:id="@+id/bottom_toolbar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:goneWhenKeyboardVisible="@{true}"
                />

Because the designers of CSS didn't have the foresight to imagine the flexibility this would bring. There are plenty of reasons to expand the content area of a box without affecting its relationship to neighbouring elements. If you think it's not possible, put some long nowrap'd text in a box, set a width on the box, and watch how the overflowed content does nothing to the layout.

Yes, this is still relevant with CSS3 in 2019; case in point: flexbox layouts. Flexbox items' margins do not collapse, so in order to space them evenly and align them with the visual edge of the container, one must subtract the items' margins from their container's padding. If any result is < 0, you must use a negative margin on the container, or sum that negative with the existing margin. I.e. the content of the element effects how one defines the margins for it, which is backwards. Summing doesn't work cleanly when flex elements' content have margins defined in different units or are affected by a different font-size, etc.

The example below should, ideally have aligned and evenly spaced grey boxes but, sadly they aren't.

I have encountered enough of these little issues over the years where a little negative padding would have gone a long way, but instead I'm forced to add non-semantic markup, use calc(), or CSS preprocessors which only work when the units are the same, etc.

--parents is copying the directory structure, so you should get rid of that.

The way you've written this, the find executes, and the output is put onto the command line such that cp can't distinguish between the spaces separating the filenames, and the spaces within the filename. It's better to do something like

$ find . -name \*.xls -exec cp {} newDir \;

in which cp is executed for each filename that find finds, and passed the filename correctly. Here's more info on this technique.

Instead of all the above, you could use zsh and simply type

$ cp **/*.xls target_directory

zsh can expand wildcards to include subdirectories and makes this sort of thing very easy.

As @David Heffeman indicates the recommendation is to use .yaml when possible, and the recommendation has been that way since September 2006.

That some projects use .yml is mostly because of ignorance of the implementers/documenters: they wanted to use YAML because of readability, or some other feature not available in other formats, were not familiar with the recommendation and and just implemented what worked, maybe after looking at some other project/library (without questioning whether what was done is correct).

The best way to approach this is to be rigorous when creating new files (i.e. use .yaml) and be permissive when accepting input (i.e. allow .yml when you encounter it), possible automatically upgrading/correcting these errors when possible.

The other recommendation I have is to document the argument(s) why you have to use .yml, when you think you have to. That way you don't look like an ignoramus, and give others the opportunity to understand your reasoning. Of course "everybody else is doing it" and "On Google .yml has more pages than .yaml" are not arguments, they are just statistics about the popularity of project(s) that have it wrong or right (with regards to the extension of YAML files). You can try to prove that some projects are popular, just because they use a .yml extension instead of the correct .yaml, but I think you will be hard pressed to do so.

Some projects realize (too late) that they use the incorrect extension (e.g. originally docker-compose used .yml, but in later versions started to use .yaml, although they still support .yml). Others still seem ignorant about the correct extension, like AppVeyor early 2019, but allow you to specify the configuration file for a project, including extension. This allows you to get the configuration file out of your face as well as giving it the proper extension: I use .appveyor.yaml instead of appveyor.yml for building the windows wheels of my YAML parser for Python).

On the other hand:

The Yaml (sic!) component of Symfony2 implements a selected subset of features defined in the YAML 1.2 version specification.

So it seems fitting that they also use a subset of the recommended extension.

Rules that tell how to compare and sort strings: letters order; whether case matters, whether diacritics matter etc.

For instance, if you want all letters to be different (say, if you store filenames in UNIX), you use UTF8_BIN collation:

SELECT  'A' COLLATE UTF8_BIN = 'a' COLLATE UTF8_BIN

---
0

If you want to ignore case and diacritics differences (say, for a search engine), you use UTF8_GENERAL_CI collation:

SELECT  'A' COLLATE UTF8_GENERAL_CI = 'ä' COLLATE UTF8_GENERAL_CI

---
1

As you can see, this collation (comparison rule) considers capital A and lowecase ä the same letter, ignoring case and diacritic differences.

A closure would work if you only need it once. I'd use a generator.

$test_array = [
    "first_key" => "first_value", 
    "second_key" => "second_value",
];

$x_result = (function(array $arr) {
    foreach ($arr as $key => $value) {
        yield "$key loves $value";
    }
})($test_array);

var_dump(iterator_to_array($x_result));

// array(2) {
//   [0]=>
//   string(27) "first_key loves first_value"
//   [1]=>
//   string(29) "second_key loves second_value"
// }

For something reusable:

function xmap(callable $cb, array $arr)
{
    foreach ($arr as $key => $value) {
        yield $cb($key, $value);
    }
}

var_dump(iterator_to_array(
    xmap(function($a, $b) { return "$a loves $b"; }, $test_array)
));

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

The skinny is that a CPU loads data from memory addresses, stores data to memory addresses, and execute instructions sequentially out of memory addresses, with some conditional jumps in the sequence of instructions processed. Each of these three categories of instructions involves computing an address to a memory cell to be used in the machine instruction. Because machine instructions are of a variable length depending on the particular instruction involved, and because we string a variable length of them together as we build our machine code, there is a two step process involved in calculating and building any addresses.

First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and building the values that will create the program as we go, and note down anyplace we need to go back and fix an address. In that place we put a dummy to just pad the location so we can continue to calculate memory size. For example our first machine code might take one cell. The next machine code might take 3 cells, involving one machine code cell and two address cells. Now our address pointer is 4. We know what goes in the machine cell, which is the op code, but we have to wait to calculate what goes in the address cells till we know where that data will be located, i.e. what will be the machine address of that data.

If there were just one source file a compiler could theoretically produce fully executable machine code without a linker. In a two pass process it could calculate all of the actual addresses to all of the data cells referenced by any machine load or store instructions. And it could calculate all of the absolute addresses referenced by any absolute jump instructions. This is how simpler compilers, like the one in Forth work, with no linker.

A linker is something that allows blocks of code to be compiled separately. This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells.

So what the compiler outputs is rough machine code that is not yet fully built, but is laid out so we know the size of everything, in other words so we can start to calculate where all of the absolute addresses will be located. the compiler also outputs a list of symbols which are name/address pairs. The symbols relate a memory offset in the machine code in the module with a name. The offset being the absolute distance to the memory location of the symbol in the module.

That's where we get to the linker. The linker first slaps all of these blocks of machine code together end to end and notes down where each one starts. Then it calculates the addresses to be fixed by adding together the relative offset within a module and the absolute position of the module in the bigger layout.

Obviously I've oversimplified this so you can try to grasp it, and I have deliberately not used the jargon of object files, symbol tables, etc. which to me is part of the confusion.

Instead of using the /regex/g syntax, you can construct a new RegExp object:

var replace = "regex";
var re = new RegExp(replace,"g");

You can dynamically create regex objects this way. Then you will do:

"mystring".replace(re, "newstring");

Try placing $PATH at the end.

export PATH=/usr/local/git/bin:/usr/local/bin:$PATH

What about summing both extremities? It would cut time in half. Like so:

1, 2, 3, 4, 5, 6, 7, 8; sum = 0

2, 3, 4, 5, 6, 7; sum = 10

3, 4, 5, 6; sum = 19

4, 5; sum = 28

sum = 37

One algorithm could be:

function sum_array(arr){
    let sum = 0,
        length = arr.length,
        half = Math.floor(length/2)

    for (i = 0; i < half; i++) {
        sum += arr[i] + arr[length - 1 - i]
    }
    if (length%2){
        sum += arr[half]
    }
    return sum
}

It performs faster when I test it on the browser with performance.now(). I think this is a better way. What do you guys think?

Another way around using cross join would be to specify column names inside cross join

select name, Subject, Marks 
from studentmarks
Cross Join (
values (Maths,'Maths'),(Science,'Science'),(English,'English')
) un(Marks, Subject)
where marks is not null;

It is the solution that I found for this problem:

//If IE

inputElement.writeAttribute("unselectable", "on");

//Other browsers

inputElement.writeAttribute("disabled", "disabled");

By using this trick, you can add style sheet to your input element that works in IE and other browsers on your not-editable input box.

Following code might be useful if someone is using React and has a different component of Marker and want to remove marker from map.

export default function useGoogleMapMarker(props) {
  const [marker, setMarker] = useState();

  useEffect(() => {
    // ...code
    const marker = new maps.Marker({ position, map, title, icon });
    // ...code
    setMarker(marker);
    return () => marker.setMap(null); // to remove markers when unmounts
  }, []);

  return marker;
}

There is no such method as slideLeft() and slideRight() which looks like slideUp() and slideDown(), but you can simulate these effects using jQuery’s animate() function.

HTML Code:

<div class="text">Lorem ipsum.</div>

JQuery Code:

  $(document).ready(function(){
    var DivWidth = $(".text").width();
    $(".left").click(function(){
      $(".text").animate({
        width: 0
      });
    });
    $(".right").click(function(){
      $(".text").animate({
        width: DivWidth
      });
    });
  });

You can see an example here: How to slide toggle a DIV from Left to Right?

The order of execution of ng-click and ng-model is ambiguous since they do not define clear priorities. Instead you should use ng-change or a $watch on the $scope to ensure that you obtain the correct values of the model variable.

In your case, this should work:

<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">

June 3, 2020 (All answers didn't worked, you can try this solution I used. Just for TimeField)

Use simple Charfield for time fields (start and end in this example) in forms.

forms.py

we can use Form or ModelForm here.

class TimeSlotForm(forms.ModelForm):
    start = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'HH:MM'}))
    end = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'HH:MM'}))

    class Meta:
        model = TimeSlots
        fields = ('start', 'end', 'provider')

Convert string input into time object in views.

import datetime
def slots():
    if request.method == 'POST':
        form = create_form(request.POST)
        if form.is_valid():                
            slot = form.save(commit=False)
            start = form.cleaned_data['start']
            end = form.cleaned_data['end']
            start = datetime.datetime.strptime(start, '%H:%M').time()
            end = datetime.datetime.strptime(end, '%H:%M').time()
            slot.start = start
            slot.end = end
            slot.save()

Please try this:

byte[] decodedString = Base64.decode(person_object.getPhoto(),Base64.NO_WRAP);
InputStream inputStream  = new ByteArrayInputStream(decodedString);
Bitmap bitmap  = BitmapFactory.decodeStream(inputStream);
user_image.setImageBitmap(bitmap);

You can use an IValueConverter for this:

<TextBlock>
    <TextBlock.Resources>
        <conv:IsNullConverter x:Key="isNullConverter"/>
    </TextBlock.Resources>
    <TextBlock.Style>
        <Style>
            <Style.Triggers>
                <DataTrigger Binding="{Binding SomeField, Converter={StaticResource isNullConverter}}" Value="False">
                    <Setter Property="TextBlock.Text" Value="It's NOT NULL Baby!"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </TextBlock.Style>
</TextBlock>

Where IsNullConverter is defined elsewhere (and conv is set to reference its namespace):

public class IsNullConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return (value == null);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new InvalidOperationException("IsNullConverter can only be used OneWay.");
    }
}

A more general solution would be to implement an IValueConverter that checks for equality with the ConverterParameter, so you can check against anything, and not just null.

You can do so by creating an array of dtype=object. If you try to assign a long string to a normal numpy array, it truncates the string:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'])
>>> a[2] = 'bananas'
>>> a
array(['apples', 'foobar', 'banana'], 
      dtype='|S6')

But when you use dtype=object, you get an array of python object references. So you can have all the behaviors of python strings:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'], dtype=object)
>>> a
array([apples, foobar, cowboy], dtype=object)
>>> a[2] = 'bananas'
>>> a
array([apples, foobar, bananas], dtype=object)

Indeed, because it's an array of objects, you can assign any kind of python object to the array:

>>> a[2] = {1:2, 3:4}
>>> a
array([apples, foobar, {1: 2, 3: 4}], dtype=object)

However, this undoes a lot of the benefits of using numpy, which is so fast because it works on large contiguous blocks of raw memory. Working with python objects adds a lot of overhead. A simple example:

>>> a = numpy.array(['abba' for _ in range(10000)])
>>> b = numpy.array(['abba' for _ in range(10000)], dtype=object)
>>> %timeit a.copy()
100000 loops, best of 3: 2.51 us per loop
>>> %timeit b.copy()
10000 loops, best of 3: 48.4 us per loop

If a method only accesses local variables, it's thread safe. Is that it?

Absolultely not. You can write a program with only a single local variable accessed from a single thread that is nevertheless not threadsafe:

https://stackoverflow.com/a/8883117/88656

Does that apply for static methods as well?

Absolutely not.

One answer, provided by @Cybis, was: "Local variables cannot be shared among threads because each thread gets its own stack."

Absolutely not. The distinguishing characteristic of a local variable is that it is only visible from within the local scope, not that it is allocated on the temporary pool. It is perfectly legal and possible to access the same local variable from two different threads. You can do so by using anonymous methods, lambdas, iterator blocks or async methods.

Is that the case for static methods as well?

Absolutely not.

If a method is passed a reference object, does that break thread safety?

Maybe.

I've done some research, and there is a lot out there about certain cases, but I was hoping to be able to define, by using just a few rules, guidelines to follow to make sure a method is thread safe.

You are going to have to learn to live with disappointment. This is a very difficult subject.

So, I guess my ultimate question is: "Is there a short list of rules that define a thread-safe method?

Nope. As you saw from my example earlier an empty method can be non-thread-safe. You might as well ask "is there a short list of rules that ensures a method is correct". No, there is not. Thread safety is nothing more than an extremely complicated kind of correctness.

Moreover, the fact that you are asking the question indicates your fundamental misunderstanding about thread safety. Thread safety is a global, not a local property of a program. The reason why it is so hard to get right is because you must have a complete knowledge of the threading behaviour of the entire program in order to ensure its safety.

Again, look at my example: every method is trivial. It is the way that the methods interact with each other at a "global" level that makes the program deadlock. You can't look at every method and check it off as "safe" and then expect that the whole program is safe, any more than you can conclude that because your house is made of 100% non-hollow bricks that the house is also non-hollow. The hollowness of a house is a global property of the whole thing, not an aggregate of the properties of its parts.

also you can use "AND" instead of "OR" if you want both attributes to be applied.

select * from tickets where (assigned_to='1') and (status='open') order by created_at desc;

You can also do the following:

CREATE TABLE #TEMPTABLE
(
    Column1 type1,
    Column2 type2,
    Column3 type3
)

INSERT INTO #TEMPTABLE
SELECT ...

SELECT *
FROM #TEMPTABLE ...

DROP TABLE #TEMPTABLE

Make sure that you update your php.ini for CLI. For my case this was C:\wamp\bin\php\php5.4.3\php.ini and uncomment extension=php_openssl.dll line.

.prop("clientWidth") and .prop("scrollWidth")

var actualInnerWidth = $("body").prop("clientWidth"); // El. width minus scrollbar width
var actualInnerWidth = $("body").prop("scrollWidth"); // El. width minus scrollbar width

in JavaScript:

var actualInnerWidth = document.body.clientWidth;     // El. width minus scrollbar width
var actualInnerWidth = document.body.scrollWidth;     // El. width minus scrollbar width

_{P.S: Note that to use scrollWidth reliably your element should not overflow horizontally}

jsBin demo

You could also use .innerWidth() but this will work only on the body element

var innerWidth = $('body').innerWidth(); // Width PX minus scrollbar 

here is a great article of how to vetical align.. I like the float way.

http://www.vanseodesign.com/css/vertical-centering/

The HTML:

<div id="main">
    <div id="floater"></div>
    <div id="inner">Content here</div>
</div>

And the corresponding style:

#main {
   height: 250px;
}

#floater {
   float: left;
   height: 50%;
   width: 100%;
   margin-bottom: -50px;
}

#inner {
   clear: both;
   height: 100px;
}

You can add this to onCreate and it will hide the keyboard every time the Activity starts.

You can also programmatically change the focus to another item.

 this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

This solution fixed my problem while replacing br tag to '\n' .

alert(content.replace(/<br\/\>/g,'\n'));

paramiko.SFTPClient

Sample Usage:

import paramiko
paramiko.util.log_to_file("paramiko.log")

# Open a transport
host,port = "example.com",22
transport = paramiko.Transport((host,port))

# Auth    
username,password = "bar","foo"
transport.connect(None,username,password)

# Go!    
sftp = paramiko.SFTPClient.from_transport(transport)

# Download
filepath = "/etc/passwd"
localpath = "/home/remotepasswd"
sftp.get(filepath,localpath)

# Upload
filepath = "/home/foo.jpg"
localpath = "/home/pony.jpg"
sftp.put(localpath,filepath)

# Close
if sftp: sftp.close()
if transport: transport.close()

This library: Android-Image-Cropper is very powerful to CropImages. It has 3,731 stars on github at this time.

You will crop your images with a few lines of code.

1 - Add the dependecies into buid.gradle (Module: app)

compile 'com.theartofdev.edmodo:android-image-cropper:2.7.+'

2 - Add the permissions into AndroidManifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

3 - Add CropImageActivity into AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
 android:theme="@style/Base.Theme.AppCompat"/>

4 - Start the activity with one of the cases below, depending on your requirements.

// start picker to get image for cropping and then use the image in cropping activity
CropImage.activity()
.setGuidelines(CropImageView.Guidelines.ON)
.start(this);

// start cropping activity for pre-acquired image saved on the device
CropImage.activity(imageUri)
.start(this);

// for fragment (DO NOT use `getActivity()`)
CropImage.activity()
.start(getContext(), this);

5 - Get the result in onActivityResult

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
    CropImage.ActivityResult result = CropImage.getActivityResult(data);
    if (resultCode == RESULT_OK) {
      Uri resultUri = result.getUri();
    } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
      Exception error = result.getError();
    }
  }
}

You can do several customizations, as set the Aspect Ratio or the shape to RECTANGLE, OVAL and a lot more.

I think this is the most simple answer. Please verify that it works:

        StackFullView.layer.isHidden = true
        Task_TopSpaceSections.constant = 0.   //your constraint of top view

If url contains a certen string, redirect to index.php . You need to match against the %{REQUEST_URI} variable to check if the url contains a certen string.

To redirect example.com/foo/bar to /index.php if the uri contains bar anywhere in the uri string , you can use this :

RewriteEngine on

RewriteCond %{REQUEST_URI} bar
RewriteRule ^ /index.php [L,R]

If you have this:

A - B <- mybranch

Where you have committed some content in commit B:

/modules/a/file1
/modules/a/file2
/modules/b/file3
/modules/b/file4

But you want to split B into C - D, and get this result:

A - C - D <-mybranch

You can divide the content like this for example (content from different directories in different commits)...

Reset the branch back to the commit before the one to split:

git checkout mybranch
git reset --hard A

Create first commit (C):

git checkout B /modules/a
git add -u
git commit -m "content of /modules/a"

Create second commit (D):

git checkout B /modules/b
git add -u
git commit -m "content of /modules/b"

You can achieve this by utilizing the jsPDF library and the toDataURL function.

I made a little demonstration:

var canvas = document.getElementById('myCanvas');_x000D_
var context = canvas.getContext('2d');_x000D_
_x000D_
// draw a blue cloud_x000D_

context.bezierCurveTo(200, 5, 150, 20, 170, 80);_x000D_
context.closePath();_x000D_

context.fillStyle = '#8ED6FF';_x000D_
context.fill();_x000D_
context.strokeStyle = '#0000ff';_x000D_
context.stroke();_x000D_

So, here is an little app that I created so you can play with the values

function parseColor(input) {
  input = input.trim();
  if (input.length > 128) {
    input = input.slice(0, 128);
  }
  if (input.charAt(0) === "#") {
    input = input.slice(1);
  }
  input = input.replace(/[^0-9A-Fa-f]/g, "0");
  while (input.length === 0 || input.length % 3 > 0) {
    input += "0";
  }
  var r = input.slice(0, input.length / 3);
  var g = input.slice(input.length / 3, input.length * 2 / 3);
  var b = input.slice(input.length * 2 / 3);
  if (r.length > 8) {
    r = r.slice(-8);
    g = g.slice(-8);
    b = b.slice(-8);
  }
  while (r.length > 2 && r.charAt(0) === "0" && g.charAt(0) === "0" && b.charAt(0) === "0") {
    r = r.slice(1);
    g = g.slice(1);
    b = b.slice(1);
  }
  if (r.length > 2) {
    r = r.slice(0, 2);
    g = g.slice(0, 2);
    b = b.slice(0, 2);
  }
  return "#" + r.padStart(2, "0") + g.padStart(2, "0") + b.padStart(2, "0");
}

$(function() {
  $("#input").on("change", function() {
    var input = $(this).val();
    var color = parseColor(input);
    var $cells = $("#result tbody td");
    $cells.eq(0).attr("bgcolor", input);
    $cells.eq(1).attr("bgcolor", color);

    var color1 = $cells.eq(0).css("background-color");
    var color2 = $cells.eq(1).css("background-color");
    $cells.eq(2).empty().append("background-color: " + input, "<br>", "getComputedStyle: " + color1);
    $cells.eq(3).empty().append("background-color: " + color, "<br>", "getComputedStyle: " + color2);
  });
});

The solutions that search a file for a substring can also search a string, eg. find or findstr.
In your case, the easy solution would be to pipe a string into the command instead of supplying a filename eg.

case-sensitive string:
echo "abcdefg" | find "bcd"

ignore case of string:
echo "abcdefg" | find /I "bcd"

IF no match found, you will get a blank line response on CMD and %ERRORLEVEL% set to 1

Others have pointed out that multiplying b by 1000 shouldn't cause a problem - but if a were zero, you'd end up losing it. (You'd get a 4 digit string instead of 5.)

Here's an alternative (general purpose) approach - which assumes that all the values are in the range 0-9. (You should quite possibly put in some code to throw an exception if that turns out not to be true, but I've left it out here for simplicity.)

public static String concatenateDigits(int... digits)
{
    char[] chars = new char[digits.length];
    for (int i = 0; i < digits.length; i++)
    {
        chars[i] = (char)(digits[i] + '0');
    }
    return new String(chars);
}

In this case you'd call it with:

String result = concatenateDigits(a, b, c, d, e);

For <input type="datetime" value="" ...

A string representing a global date and time.

Value: A valid date-time as defined in [RFC 3339], with these additional qualifications:

•the literal letters T and Z in the date/time syntax must always be uppercase

•the date-fullyear production is instead defined as four or more digits representing a number greater than 0

Examples:

1990-12-31T23:59:60Z

1996-12-19T16:39:57-08:00

http://www.w3.org/TR/html-markup/input.datetime.html#input.datetime.attrs.value

Update:

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The HTML was a control for entering a date and time (hour, minute, second, and fraction of a second) as well as a timezone. This feature has been removed from WHATWG HTML, and is no longer supported in browsers.

Instead, browsers are implementing (and developers are encouraged to use) the datetime-local input type.

Why is HTML5 input type datetime removed from browsers already supporting it?

Here's a method I use which works and is easy to implement. This will require both the fpdf and fpdi libraries which can be downloaded here:

• FPDF: http://www.fpdf.org/en/download.php
• FPDI: https://www.setasign.com/products/fpdi/downloads

require('fpdf.php');
require('fpdi.php');

$files = ['doc1.pdf', 'doc2.pdf', 'doc3.pdf'];

$pdf = new FPDI();

foreach ($files as $file) {
    $pdf->setSourceFile($file);
    $tpl = $pdf->importPage(1, '/MediaBox');
    $pdf->addPage();
    $pdf->useTemplate($tpl);
}

$pdf->Output('F','merged.pdf');

I was able to get past this in typescript using something like:

let x = [ //data inside array ];
let y = new Map<any, any>();
for (var i=0; i<x.length; i++) {
    y.set(x[i], //value for this key here);
}

This seemed to be the only way that I could use the values inside X as keys for the map Y and compile.

Kind of related on the answer by J. F. Sebastian, but more direct.

If you are having this problem when printing to the console/terminal, then do this:

>set PYTHONIOENCODING=UTF-8

Removing only decimal part can be done as follows:

number.replace(/(\.\d+)+/,'');

This would convert 13.6667px into 13px (leaving units px untouched).

If you need it to work in IE7, you can't use the undocumented, buggy, and unsupported {'width':'auto'} option. Instead, add the following to your .dialog():

'open': function(){ $(this).dialog('option', 'width', this.scrollWidth) }

Whether .scrollWidth includes the right-side padding depends on the browser (Firefox differs from Chrome), so you can either add a subjective "good enough" number of pixels to .scrollWidth, or replace it with your own width-calculation function.

You might want to include width: 0 among your .dialog() options, since this method will never decrease the width, only increase it.

Tested to work in IE7, IE8, IE9, IE10, IE11, Firefox 30, Chrome 35, and Opera 22.

Try this using list comprehension:

import pandas as pd

df = pd.DataFrame(
    [p, p.team, p.passing_att, p.passer_rating()] for p in game.players.passing()
)

Simply cereate a dummy repo, open a new issue and use @xxxxx to notify the affected user.

If user has notification via e-mail enabled he will get an e-mail, if not he will notice on next login.

No need to search for e-mail adress in commits or activity stream and privacy is respected.

Do a GROUP BY after the ORDER BY by wrapping your query with the GROUP BY like this:

SELECT t.* FROM (SELECT * FROM table ORDER BY time DESC) t GROUP BY t.from

If Table variable has large data, then instead of table variable(@table) create temp table (#table).table variable doesn't allow to create index after insert.

 CREATE TABLE #Table(C1 int,       
  C2 NVarchar(100) , C3 varchar(100)
  UNIQUE CLUSTERED (c1) 
 ); 

1. Create table with unique clustered index

2. Insert data into Temp "#Table" table

3. Create non clustered indexes.

    CREATE NONCLUSTERED INDEX IX1  ON #Table (C2,C3);
   

After searching different websites looking for a solution as to how to separate the full path from the file name once the full one-piece information has been obtained from the Open File Dialog, and seeing how "complex" the solutions given were for an Excel newcomer like me, I wondered if there could be a simpler solution. So I started to work on it on my own and I came to this possibility. (I have no idea if somebody got the same idea before. Being so simple, if somebody has, I excuse myself.)

Dim fPath As String
Dim fName As String
Dim fdString As String

fdString = (the OpenFileDialog.FileName)

'Get just the path by finding the last "\" in the string from the end of it
 fPath = Left(fdString, InStrRev(fdString, "\"))

'Get just the file name by finding the last "\" in the string from the end of it
 fName = Mid(fdString, InStrRev(fdString, "\") + 1)

'Just to check the result
 Msgbox "File path: " & vbLF & fPath & vbLF & vblF & "File name: " & vbLF & fName

AND THAT'S IT!!! Just give it a try, and let me know how it goes...

The property IsOneWay=true may be true in the Operational contract of the interface. Remove that property to get rid of this error.

self.tableView.style = UITableViewStyleGrouped

EDIT:

Had assumed this was a read/write property. In that case, you can either follow Dimitris advice and set the style when you instantiate the controller, or (if you're using a XIB), you can set it via IB.

Why not get rid of the inline javascript and do something like this instead?

Inline javascript is considered bad practice as it is outdated.

Notes

Why use addEventListener?

addEventListener is the way to register an event listener as specified in W3C DOM. Its benefits are as follows:

It allows adding more than a single handler for an event. This is particularly useful for DHTML libraries or Mozilla extensions that need to work well even if other libraries/extensions are used. It gives you finer-grained control of the phase when the listener gets activated (capturing vs. bubbling) It works on any DOM element, not just HTML elements.

<a id="back" href="www.mypage.com"> Link </a>

document.getElementById("back").addEventListener("click", window.history.back, false);

In case you only need to delete the header from the csv file, you can work more efficiently if you write using the standard Python file I/O library, avoiding writing with the CSV Python library:

with open("tmob_notcleaned.csv", "rb") as infile, open("tmob_cleaned.csv", "wb") as outfile:
   next(infile)  # skip the headers
   outfile.write(infile.read())

The repository is not down, it looks like they've changed how they host files (I guess they have restored some old code):

Now you have to add the /package-name/ before the -

Eg:

http://registry.npmjs.org/-/npm-1.1.48.tgz
http://registry.npmjs.org/npm/-/npm-1.1.48.tgz

There are 3 ways to solve it:

• Use a complete mirror:

• Use a public proxy:

  --registry http://165.225.128.50:8000

• Host a local proxy:

  https://github.com/hughsk/npm-quickfix

git clone https://github.com/hughsk/npm-quickfix.git
cd npm-quickfix
npm set registry http://localhost:8080/
node index.js

I'd personally go with number 3 and revert to npm set registry http://registry.npmjs.org/ as soon as this get resolved.

yes datediff is implemented; see: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF

By the way I found this by Google-searching "hive datediff", it was the first result ;)

I am using the code above but I have changed the delay effect by slideToggle.

It slides the dropdown on hover with animation.

$('.navbar .dropdown').hover(function() {
    $(this).find('.dropdown-menu').first().stop(true, true).slideToggle(400);
    }, function() {
    $(this).find('.dropdown-menu').first().stop(true, true).slideToggle(400)
    });

Open CMD with administrative access(Right click then run as administrator) then type the following command there:

set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib

Replace My_python_lib with the folder name of your installed python like for me it was C:\python27. Then to check if the path variable is set, type echo %PATH% you'll see your python part in the end. Hence now python is accessible. From this tutorial

There is an ActiveState recipe which implements a basic scanf http://code.activestate.com/recipes/502213-simple-scanf-implementation/

You should make x and y numpy arrays, not lists:

x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,
              0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78])
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,
              0.478,0.335,0.365,0.424,0.390,0.585,0.511])

With this change, it produces the expect plot. If they are lists, m * x will not produce the result you expect, but an empty list. Note that m is anumpy.float64 scalar, not a standard Python float.

I actually consider this a bit dubious behavior of Numpy. In normal Python, multiplying a list with an integer just repeats the list:

In [42]: 2 * [1, 2, 3]
Out[42]: [1, 2, 3, 1, 2, 3]

while multiplying a list with a float gives an error (as I think it should):

In [43]: 1.5 * [1, 2, 3]
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-43-d710bb467cdd> in <module>()
----> 1 1.5 * [1, 2, 3]
TypeError: can't multiply sequence by non-int of type 'float'

The weird thing is that multiplying a Python list with a Numpy scalar apparently works:

In [45]: np.float64(0.5) * [1, 2, 3]
Out[45]: []

In [46]: np.float64(1.5) * [1, 2, 3]
Out[46]: [1, 2, 3]

In [47]: np.float64(2.5) * [1, 2, 3]
Out[47]: [1, 2, 3, 1, 2, 3]

So it seems that the float gets truncated to an int, after which you get the standard Python behavior of repeating the list, which is quite unexpected behavior. The best thing would have been to raise an error (so that you would have spotted the problem yourself instead of having to ask your question on Stackoverflow) or to just show the expected element-wise multiplication (in which your code would have just worked). Interestingly, addition between a list and a Numpy scalar does work:

In [69]: np.float64(0.123) + [1, 2, 3]
Out[69]: array([ 1.123,  2.123,  3.123])

Using this you can run it as eplot -T to get ASCII-graphics result instead of a gnuplot window.

This is how I would do it:

$terms = array('BMW', 'Audi', 'Porsche', 'Honda');
// -- purge 'make' Porsche from terms --
if (!empty($terms)) {
    $pos = '';
    $pos = array_search('Porsche', $terms);
    if ($pos !== false) unset($terms[$pos]);
}

You can use getTime() method to convert the Date to the number of milliseconds since January 1, 1970. Then you can easy do any arithmetic operations with the dates. Of course you can convert the number back to the Date with setTime(). See here an example.

const exec = require("child_process").exec
exec("ls", (error, stdout, stderr) => {
 //do whatever here
})

I agree with Levik as the parent container is set to 100% if you have sidebars and want them to fill the space to meet up with the footer you cannot set them to 100% because they will be 100 percent of the parent height as well which means that the footer ends up getting pushed down when using the clear function.

Think of it this way if your header is say 50px height and your footer is 50px height and the content is just autofitted to the remaining space say 100px for example and the page container is 100% of this value its height will be 200px. Then when you set the sidebar height to 100% it is then 200px even though it is supposed to fit snug in between the header and footer. Instead it ends up being 50px + 200px + 50px so the page is now 300px because the sidebars are set to the same height as the page container. There will be a big white space in the contents of the page.

I am using internet Explorer 9 and this is what I am getting as the effect when using this 100% method. I havent tried it in other browsers and I assume that it may work in some of the other options. but it will not be universal.

How about sys.exit() from the module sys.

If sys.exit() is executed from within a thread it will close that thread only.

This answer here talks about that: Why does sys.exit() not exit when called inside a thread in Python?

If you want to automate the creating of a custom divergent colormap commonly used for surface plots, this module combined with @unutbu method worked well for me.

def diverge_map(high=(0.565, 0.392, 0.173), low=(0.094, 0.310, 0.635)):
    '''
    low and high are colors that will be used for the two
    ends of the spectrum. they can be either color strings
    or rgb color tuples
    '''
    c = mcolors.ColorConverter().to_rgb
    if isinstance(low, basestring): low = c(low)
    if isinstance(high, basestring): high = c(high)
    return make_colormap([low, c('white'), 0.5, c('white'), high])

The high and low values can be either string color names or rgb tuples. This is the result using the surface plot demo:

While the accepted answer is correct, I'll add a more elegant version (in my opinion):

boolean idExists = tabPane.getTabs().stream()
    .map(Tab::getId)
    .anyMatch(idToCheck::equals);

Don't neglect using Stream#map() which allows to flatten the data structure before applying the Predicate.

You can also use truncate.

truncate table table_name;

If you need Set rather than List, you can use EnumSet.allOf().

Set<EnumerationClass> set = EnumSet.allOf(EnumerationClass.class);

Update: JakeRobb is right. My answer is about java.lang.Enum instead of java.util.Enumeration. Sorry for unrelated answer.

I used this to retrieve data from MySql Database:

AccessText a = new AccessText();    
a.Text=reader[1].ToString();       // MySql reader
a.Width = 70;
a.TextWrapping = TextWrapping.WrapWithOverflow;
labels[i].Content = a;

I think that you're stuck with the workaround you mentioned in your edit.

I would start by converting every formula on the sheet to text roughly like this:

Dim r As Range

For Each r In Worksheets("Sheet1").UsedRange
    If (Left$(r.Formula, 1) = "=") Then
        r.Formula = "'ZZZ" & r.Formula
    End If
Next r

where the 'ZZZ uses the ' to signify a text value and the ZZZ as a value that we can look for when we want to convert the text back to being a formula. Obviously if any of your cells actually start with the text ZZZ then change the ZZZ value in the VBA macro to something else

When the re-arranging is complete, I would then convert the text back to a formula like this:

For Each r In Worksheets("Sheet1").UsedRange
    If (Left$(r.Formula, 3) = "ZZZ") Then
        r.Formula = Mid$(r.Formula, 4)
    End If
Next r

One real downside to this method is that you can't see the results of any formula while you are re-arranging. You may find that when you convert back from text to formula that you have a slew of #REF errors for example.

It might be beneficial to work on this in stages and convert back to formulas every so often to check that no catastrophes have occurred

I spent a whole day on this error

if you are working with n-tear architecture

or you tried to separate Models generated by EDMX form DataAccessLayer to DomainModelLayer

maybe you will get this error

1. First troubleshooting step is to make sure the Connection string in webconfig (UILayer)and appconfig (DataAccessLayer) are the same

2. Second which is Very important the connection string

   connectionString="metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provid.....
   

   which is the problem

from where on earth I got Modelor whatever .csdl in my connection string where are they

here I our solution look at the picture

hope the help you

If you really want a thematic break, by all means use the <hr> tag.

If you just want a design line, you could use something like the css class

.hline-bottom {
    padding-bottom: 10px;
    border-bottom: 2px solid #000; /* whichever color you prefer */
}

and use it like

<div class="block_1 hline-bottom">Cheese</div>

You need a more specific expression. Try grep " OK$" or grep "[0-9]* OK". You want to choose a pattern that matches what you want, but won't match what you don't want. That pattern will depend upon what your whole file contents might look like.

You can also do: grep -w "OK" which will only match a whole word "OK", such as "1 OK" but won't match "1OK" or "OKFINE".

$ cat test.txt | grep -w "OK"
1 OK
2 OK
4 OK

You have mixed indentation formatting (spaces and tabs)

On Notepad++

Change Tab Settings to 4 spaces

Go to Settings -> Preferences -> Tab Settings -> Replace by spaces

Fix the current file mixed indentations

Select everything CTRL+A

Click TAB once, to add an indentation everywhere

Run SHIFT + TAB to remove the extra indentation, it will replace all TAB characters to 4 spaces.

Since mysql_* are deprecated, so here is the solution using mysqli.

$mysqli = new mysqli('host', 'username', 'password', 'database');
if($mysqli->connect_errno>0)
{
  die("Connection to MySQL-server failed!"); 
}
$resultArr = array();//to store results
//to execute query
$executingFetchQuery = $mysqli->query("SELECT `name` FROM customers WHERE 1");
if($executingFetchQuery)
{
   while($arr = $executingFetchQuery->fetch_assoc())
   {
        $resultArr[] = $arr['name'];//storing values into an array
   }
}
print_r($resultArr);//print the rows returned by query, containing specified columns

There is another way to do this using PDO

  $db = new PDO('mysql:host=host_name;dbname=db_name', 'username', 'password'); //to establish a connection
  //to fetch records
  $fetchD = $db->prepare("SELECT `name` FROM customers WHERE 1");
  $fetchD->execute();//executing the query
  $resultArr = array();//to store results
  while($row = $fetchD->fetch())
  {
     $resultArr[] = $row['name'];
  }
  print_r($resultArr);

The client has a pre-seeded store of SSL certificate authorities' public keys. There must be a chain of trust from the certificate for the server up through intermediate authorities up to one of the so-called "root" certificates in order for the server to be trusted.

You can examine and/or alter the list of trusted authorities. Often you do this to add a certificate for a local authority that you know you trust - like the company you work for or the school you attend or what not.

The pre-seeded list can vary depending on which client you use. The big SSL certificate vendors insure that their root certs are in all the major browsers ($$$).

Monkey-in-the-middle attacks are "impossible" unless the attacker has the private key of a trusted root certificate. Since the corresponding certificates are widely deployed, the exposure of such a private key would have serious implications for the security of eCommerce generally. Because of that, those private keys are very, very closely guarded.

Xamarin port of Felix's answer

In your MainActivity, add this (docs: Android.App.IntentFilterAttribute Class):

....
[IntentFilter(new[] { 
    Intent.ActionView }, 
    Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable }, 
    DataScheme = "my.special.scheme")
]
public class MainActivity : Activity
{
    ....

Xamarin will add following in the AndroidManifest.xml for you:

<activity
    android:label="Something"
    android:screenOrientation="portrait"
    android:theme="@style/MyTheme"
    android:name="blah.MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="my.special.scheme" />
    </intent-filter>
</activity>

And in order to get params (I tested in OnCreate of MainActivity):

var data = Intent.Data;
if (data != null)
{
    var scheme = data.Scheme;
    var host = data.Host;
    var args = data.PathSegments;

    if (args.Count > 0)
    {
        var first = args[0];
        var second = args[1];
        ...
    }
}

As far as I know, above can be added in any activity, not only MainActivity

Notes:

1. When user click on the link, Android OS relaunch your app (kill prev instance, if any, and run new one), means the OnCreate event of app's MainLauncher Activity will be fired again.
2. With this link: <a href="my.special.scheme://host/arg1/arg2">, in above last code snippet values will be:

scheme: my.special.scheme
host: host
args: ["arg1", "arg2"]
first: arg1
second: arg2

Update: if android creates new instance of your app, you should add android:launchMode="singleTask" too.

Intel's picture is helpful, as shown by Tortuga's best answer. Here's a caption for it.

Processor: One semiconductor chip, the CPU (central processing unit) seated in one socket, circa 1950s-2010s. Over time, more functions have been packed onto the CPU chip. Prior to the 1950s releases of single-chip processors, one processor might have spread across multiple chips. In the mid 2010s the system-on-a-chip chips made it slightly more sketchy to equate one processor to one chip, though that's generally what people mean by processor, as in "this computer has an i7 processor" or "this computer system has four processors."

Core: One block of a CPU, executing one instruction at a time. (You'll see people say one instruction per clock cycle, but some CPUs use multiple clock cycles for some instructions.)

var last = array.slice(-1)[0];

I find slice at -1 useful for getting the last element (especially of an array of unknown length) and the performance is much better than calculating the length less 1.

Mozilla Docs on Slice

Performance of the various methods for selecting last array element

Very simple, no library required:

var date = new Date();
var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);

or you might prefer:

var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);

EDIT

Some browsers will treat two digit years as being in the 20th century, so that:

new Date(14, 0, 1);

gives 1 January, 1914. To avoid that, create a Date then set its values using setFullYear:

var date = new Date();
date.setFullYear(14, 0, 1); // 1 January, 14

Just revisiting this, I've made it a little bit tidier (though someone who is full bottle on Prototype/JavaScript could suggest improvements?).

var TextAreaResize = Class.create();
TextAreaResize.prototype = {
  initialize: function(element, options) {
    element = $(element);
    this.element = element;

    this.options = Object.extend(
      {},
      options || {});

    Event.observe(this.element, 'keyup',
      this.onKeyUp.bindAsEventListener(this));
    this.onKeyUp();
  },

  onKeyUp: function() {
    // We need this variable because "this" changes in the scope of the
    // function below.
    var cols = this.element.cols;

    var linecount = 0;
    $A(this.element.value.split("\n")).each(function(l) {
      // We take long lines into account via the cols divide.
      linecount += 1 + Math.floor(l.length / cols);
    })

    this.element.rows = linecount;
  }
}

Just it call with:

new TextAreaResize('textarea_id_name_here');

Here are the steps:

1. Start the command line.
2. Enter the folder containing the .m file with cd C:\M1\M2\M3
3. Run the following: C:\E1\E2\E3\matlab.exe -r mfile

Windows systems will use your current folder as the location for MATLAB to search for .m files, and the -r option tries to start the given .m file as soon as startup occurs.

in School,

public void addTeacherName(classroom classroom, String teacherName) {
    classroom.setTeacherName(teacherName);
}

BTW, use Pascal Case for class names. Also, I would suggest a Map<String, classroom> to map a classroom name to a classroom.

Then, if you use my suggestion, this would work

public void addTeacherName(String className, String teacherName) {
    classrooms.get(className).setTeacherName(teacherName);
}

I haven't used Cassandra, but I have used MongoDB and think it's awesome.

If you're after simple setup, this is it: You simply untar MongoDB and run the mongod daemon and that's it ... it's running.

Obviously that's only a starter, but to get you started it's easy.

No, there is not really any other way : if you have many locations and want to display them on a map, the best solution is to :

• fetch the latitude+longitude, using the geocoder, when a location is created
• store those in your database, alongside the address
• and use those stored latitude+longitude when you want to display the map.

This is, of course, considering that you have a lot less creation/modification of locations than you have consultations of locations.

Yes, it means you'll have to do a bit more work when saving the locations -- but it also means :

• You'll be able to search by geographical coordinates
  • i.e. "I want a list of points that are near where I'm now"
• Displaying the map will be a lot faster
  • Even with more than 20 locations on it
• Oh, and, also (last but not least) : this will work ;-)
  • You will less likely hit the limit of X geocoder calls in N seconds.
  • And you will less likely hit the limit of Y geocoder calls per day.

For Redmi and Mi devices turn off MIUI Optimization

You are not breaking code over multiple lines, but rather a single identifier. There is a difference.

For your issue, try

R> setwd(paste("~/a/very/long/path/here",
               "/and/then/some/more",
               "/and/then/some/more",
               "/and/then/some/more", sep=""))

which also illustrates that it is perfectly fine to break code across multiple lines.

Starting with Spring Boot 1.2, you can configure SSL using application.properties or application.yml. Here's an example for application.properties:

server.port = 8443
server.ssl.key-store = classpath:keystore.jks
server.ssl.key-store-password = secret
server.ssl.key-password = another-secret

Same thing with application.yml:

server:
  port: 8443
  ssl:
    key-store: classpath:keystore.jks
    key-store-password: secret
    key-password: another-secret

Here's a link to the current reference documentation.

Of course, never fails. Found the solution about a minute after posting the above question... solution for those that may have had the same issue:

For example here is a element like button for adding item to basket and appropriate attributes for saving in localStorage.

'<a href="#" cartBtn pr_id='+e.id+' pr_name_en="'+e.nameEn+'" pr_price="'+e.price+'" pr_image="'+e.image+'" class="btn btn-primary"><i class="fa fa-shopping-cart"></i>Add to cart</a>'

var productArray=[];


$(document).on('click','[cartBtn]',function(e){
  e.preventDefault();
  $(this).html('<i class="fa fa-check"></i>Added to cart');
  console.log('Item added ');
  var productJSON={"id":$(this).attr('pr_id'), "nameEn":$(this).attr('pr_name_en'), "price":$(this).attr('pr_price'), "image":$(this).attr('pr_image')};


  if(localStorage.getObj('product')!==null){
    productArray=localStorage.getObj('product');
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }
  else{
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }


});

Storage.prototype.setObj = function(key, value) {
    this.setItem(key, JSON.stringify(value));
}

Storage.prototype.getObj = function(key) {
    var value = this.getItem(key);
    return value && JSON.parse(value);

After adding JSON object to Array result is (in LocalStorage):

[{"id":"99","nameEn":"Product Name1","price":"767","image":"1462012597217.jpeg"},{"id":"93","nameEn":"Product Name2","price":"76","image":"1461449637106.jpeg"},{"id":"94","nameEn":"Product Name3","price":"87","image":"1461449679506.jpeg"}]

after this action you can easily send data to server as List in Java

How do I store a simple cart using localStorage?

What if you specified the default value to return, instead of using default(T)?

public static T GetQueryString<T>(string key, T defaultValue) {...}

It makes calling it easier too:

var intValue = GetQueryString("intParm", Int32.MinValue);
var strValue = GetQueryString("strParm", "");
var dtmValue = GetQueryString("dtmPatm", DateTime.Now); // eg use today's date if not specified

The downside being you need magic values to denote invalid/missing querystring values.

For integer values represented by a double, you can use this code, which is much faster than the other solutions.

public static String doubleToString(final double d) {
    // check for integer, also see https://stackoverflow.com/a/9898613/868941 and
    // https://github.com/google/guava/blob/master/guava/src/com/google/common/math/DoubleMath.java
    if (isMathematicalInteger(d)) {
        return Long.toString((long)d);
    } else {
        // or use any of the solutions provided by others, this is the best
        DecimalFormat df = 
            new DecimalFormat("0", DecimalFormatSymbols.getInstance(Locale.ENGLISH));
        df.setMaximumFractionDigits(340); // 340 = DecimalFormat.DOUBLE_FRACTION_DIGITS
        return df.format(d);
    }
}

// Java 8+
public static boolean isMathematicalInteger(final double d) {
    return StrictMath.rint(d) == d && Double.isFinite(d);
}

Elaborating on this answer and this answer.

Above answers point out the problem of many of the solutions here which don't iterate by code point value -- they would have trouble with any surrogate chars. The java docs also outline the issue here (see "Unicode Character Representations"). Anyhow, here's some code that uses some actual surrogate chars from the supplementary Unicode set, and converts them back to a String. Note that .toChars() returns an array of chars: if you're dealing with surrogates, you'll necessarily have two chars. This code should work for any Unicode character.

    String supplementary = "Some Supplementary: ";
    supplementary.codePoints().forEach(cp -> 
            System.out.print(new String(Character.toChars(cp))));

var query = from c in obj.tbCourses
        where ...
        select c;

Then you can use:

List<course> list_course= query.ToList<course>();

It works fine for me.

I want to improve on @adf88's answer. I feel that pseudocode for the STDCALL does not reflect the way of how it happens in reality. 'a', 'b', and 'c' aren't popped from the stack in the function body. Instead they are popped by the ret instruction (ret 12 would be used in this case) that in one swoop jumps back to the caller and at the same time pops 'a', 'b', and 'c' from the stack.

Here is my version corrected according to my understanding:

STDCALL:

/* 1. calling STDCALL in pseudo-assembler (similar to what the compiler outputs) */
push on the stack a copy of 'z', then copy of 'y', then copy of 'x'
call
move contents of register A to 'i' variable

/* 2. STDCALL 'Function' body in pseaudo-assembler */
copy 'a' (from stack) to register A
copy 'b' (from stack) to register B
add A and B, store result in A
copy 'c' (from stack) to register B
add A and B, store result in A
jump back to caller code and at the same time pop 'a', 'b' and 'c' off the stack (a, b and
c are removed from the stack in this step, result in register A)

Adjusted to allow for daylight saving differences. try this:

  function daysBetween(date1, date2) {

 // adjust diff for for daylight savings
 var hoursToAdjust = Math.abs(date1.getTimezoneOffset() /60) - Math.abs(date2.getTimezoneOffset() /60);
 // apply the tz offset
 date2.addHours(hoursToAdjust);

    var date2_ms = date2.getTime()

    // Calculate the difference in milliseconds
    var difference_ms = Math.abs(date1_ms - date2_ms)

    // Convert back to days and return
    return Math.round(difference_ms/ONE_DAY)

}

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

If you transferred these files through disk or other means, it is likely they were not saved properly.

Below is one of the way by which you can achieve that, may not be an ideal way to do.

Have one method accepting both types of request, then check what type of request you received, is it of type "GET" or "POST", once you come to know that, do respective actions and the call one method which does common task for both request Methods ie GET and POST.

@RequestMapping(value = "/books")
public ModelAndView listBooks(HttpServletRequest request){
     //handle both get and post request here
     // first check request type and do respective actions needed for get and post.

    if(GET REQUEST){

     //WORK RELATED TO GET

    }else if(POST REQUEST){

      //WORK RELATED TO POST

    }

    commonMethod(param1, param2....);
}

Where you want to set your location? you can use mapkit api to show u location's. see icodeblog.com for more detail on how to use mapkit. Also you can store your desired cordinates just create an object CLLocation2D *location; location.longitude=your desired longitude value; location.latitude=your desired latitude value;

What you can do is use delimeter as new line. Till you press enter key you will be able to read it as string.

Scanner sc = new Scanner(System.in);
sc.useDelimiter(System.getProperty("line.separator"));

Hope this helps.

In this case, ' is not a comment character. It's used to delimit string literals. The comic artist is banking on the idea that the school in question has dynamic sql somewhere that looks something like this:

$sql = "INSERT INTO `Students` (FirstName, LastName) VALUES ('" . $fname . "', '" . $lname . "')";

So now the ' character ends the string literal before the programmer was expecting it. Combined with the ; character to end the statement, an attacker can now add whatever sql they want. The -- comment at the end is to make sure any remaining sql in the original statement does not prevent the query from compiling on the server.

FWIW, I also think the comic in question has an important detail wrong: if you're thinking about sanitizing your database inputs, as the comic suggests, you're still doing it wrong. Instead, you should think in terms of quarantining your database inputs, and the correct way to do this is via parameterized queries.

I'm running Eclipse 4.2.0 (Juno) and PyDev 2.8.1, and ran into this problem with a lib installed to my site-packages path. According to this SO question:

Pydev and *.pyc Files

...there is an issue with PyDev and pyc files. In the case of the particular lib I tried to reference, all that is delivered is pyc files.

Here's what I did to address this:

1. Install uncompyle2 from https://github.com/Mysterie/uncompyle2

2. Run uncompyle2 against the *.pyc files in the site-packages lib. Example:

   uncompyle2 -r -o /tmp /path/to/site-packages/lib

3. Rename the resulting *.pyc_dis files produced from uncompyle2 to *.py
4. Move / copy these *.py files to the site-packages path
5. In Eclipse, select File > Restart

The unresolved import error relating to .pyc files should now disappear.

parseInt() should do the trick

var number = "25";
var sum = parseInt(number, 10) + 10;
var pin = number + 10;

Gives you

sum == 35
pin == "2510"

http://www.w3schools.com/jsref/jsref_parseint.asp

Note: The 10 in parseInt(number, 10) specifies decimal (base-10). Without this some browsers may not interpret the string correctly. See MDN: parseInt.

In Designer, activate the centralWidget and assign a layout, e.g. horizontal or vertical layout. Then your QFormLayout will automatically resize.

Always make sure, that all widgets have a layout! Otherwise, automatic resizing will break with that widget!

DATE_ADD works correctly. 1 January plus 6 months is 1 July, just like 1 January plus 1 month is 1 of February.

Between operation is inclusive. So, you are getting everything up to, and including, 1 July. (see also MySQL "between" clause not inclusive?)

What you need to do is subtract 1 day or use < operator instead of between.

You haven't created an event. To do that write:

public event EventHandler<Progress> Progress;

Then, you can call Progress from within the class where it was declared like normal function or delegate:

Progress(this, new Progress("some status"));

So, if you want to report progress in TestClass, the event should be in there too and it should be also static. You can the subscribe to it from your form like this:

TestClass.Progress += SetStatus;

Also, you should probably rename Progress to ProgressEventArgs, so that it's clear what it is.

I have a slightly different perspective on the difference between a DATETIME and a TIMESTAMP. A DATETIME stores a literal value of a date and time with no reference to any particular timezone. So, I can set a DATETIME column to a value such as '2019-01-16 12:15:00' to indicate precisely when my last birthday occurred. Was this Eastern Standard Time? Pacific Standard Time? Who knows? Where the current session time zone of the server comes into play occurs when you set a DATETIME column to some value such as NOW(). The value stored will be the current date and time using the current session time zone in effect. But once a DATETIME column has been set, it will display the same regardless of what the current session time zone is.

A TIMESTAMP column on the other hand takes the '2019-01-16 12:15:00' value you are setting into it and interprets it in the current session time zone to compute an internal representation relative to 1/1/1970 00:00:00 UTC. When the column is displayed, it will be converted back for display based on whatever the current session time zone is. It's a useful fiction to think of a TIMESTAMP as taking the value you are setting and converting it from the current session time zone to UTC for storing and then converting it back to the current session time zone for displaying.

If my server is in San Francisco but I am running an event in New York that starts on 9/1/1029 at 20:00, I would use a TIMESTAMP column for holding the start time, set the session time zone to 'America/New York' and set the start time to '2009-09-01 20:00:00'. If I want to know whether the event has occurred or not, regardless of the current session time zone setting I can compare the start time with NOW(). Of course, for displaying in a meaningful way to a perspective customer, I would need to set the correct session time zone. If I did not need to do time comparisons, then I would probably be better off just using a DATETIME column, which will display correctly (with an implied EST time zone) regardless of what the current session time zone is.

TIMESTAMP LIMITATION

The TIMESTAMP type has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC and so it may not usable for your particular application. In that case you will have to use a DATETIME type. You will, of course, always have to be concerned that the current session time zone is set properly whenever you are using this type with date functions such as NOW().

jQuery Library must be in the head section then.

Personally:

This worked for me:

IWebElement element = driver.FindElements(getApplicationObject(currentObjectName, currentObjectType, currentObjectUniqueId))[0];
 ((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].scrollIntoView(true);", element);

Add "ref" to h1 tag :

<h1 ref="source">Hey there.</h1>

and
const { source } = this.props; change to const { source } = this.refs;

First of all, try to connect to the LAN IP of your server. If IIS is set up with only one web site, chances are that your site is going to pop up.

If you want to access it by name, you would have to add an entry in the HOSTS file of every client PC you want to view the site with (not to 127.0.0.1 obviously, but to the local IP address of your server).

Also, your Firewall needs to be configured to accept incoming calls on Port 80.

This is usually the point where it makes more sense to set up a DNS service that you can register names like "mysite.dev" with centrally, without having to dabble with hosts files. But that's a different story, and belongs to superuser.com or serverfault.com.

Immediately following your <body> tag add something like this...

 <style> body  {opacity:0;}</style>

And for the very first thing in your <head> add something like...

 <script>
  window.onload = function() {setTimeout(function(){document.body.style.opacity="100";},500);};
 </script>

As far as this being good practice or bad depends on your visitors, and the time the wait takes.

The question that is stil left open and I am not seeing any answers here is how to be sure the page has stabilized. For example if you are loading fonts the page may reflow a bit until all the fonts are loaded and displayed. I would like to know if there is an event that tells me the page is done rendering.

My understanding of marshalling is different to the other answers.

Serialization:

To Produce or rehydrate a wire-format version of an object graph utilizing a convention.

Marshalling:

To Produce or rehydrate a wire-format version of an object graph by utilizing a mapping file, so that the results can be customized. The tool may start by adhering to a convention, but the important difference is the ability to customize results.

Contract First Development:

Marshalling is important within the context of contract first development.

• Its possible to make changes to an internal object graph, while keeping the external interface stable over time. This way all of the service subscribers won't have to be modified for every trivial change.
• Its possible to map the results across different languages. For example from the property name convention of one language ('property_name') to another ('propertyName').

 SELECT * FROM all_procedures WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE') 
 and owner = 'Schema_name' order by object_name

here 'Schema_name' is a name of schema, example i have a schema named PMIS, so the example will be

SELECT * FROM all_procedures WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE') 
and owner = 'PMIS' order by object_name

CAUSE: "Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app." In this case, "ACCESS_FINE_LOCATION" is a "dangerous permission and for that reason, you get this 'java.lang.SecurityException: "gps" location provider requires ACCESS_FINE_LOCATION permission.' error (https://developer.android.com/training/permissions/requesting.html).

SOLUTION: Implementing the code provided at https://developer.android.com/training/permissions/requesting.html under the "Request the permissions you need" and "Handle the permissions request response" headings.

You can use a CSS3 transition for this. Have a look at this example:

http://jsfiddle.net/ujDkf/1/

Here is the main code:

#box {
  position : relative;
  width : 100px;
  height : 100px;
  background-color : gray;
  border : 5px solid black;
  -webkit-transition : border 500ms ease-out;
  -moz-transition : border 500ms ease-out;
  -o-transition : border 500ms ease-out;
  transition : border 500ms ease-out;
}

#box:hover {
   border : 10px solid red;   
}

Keep in mind though that passing arguments on Activator.CreateInstance has a significant performance difference versus parameterless creation.

There are better alternatives for dynamically creating objects using pre compiled lambda. Of course always performance is subjective and it clearly depends on each case if it's worth it or not.

Details about the issue on this article.

Graph is taken from the article and represents time taken in ms per 1000 calls.

to position the dialog in the center of the screen :

$('#my-selector').parent().position({
                    my: "center",
                    at: "center",
                    of: window
});

Try something like this to get the format you wanted:

Get-WebBinding | % {
    $name = $_.ItemXPath -replace '(?:.*?)name=''([^'']*)(?:.*)', '$1'
    New-Object psobject -Property @{
        Name = $name
        Binding = $_.bindinginformation.Split(":")[-1]
    }
} | Group-Object -Property Name | 
Format-Table Name, @{n="Bindings";e={$_.Group.Binding -join "`n"}} -Wrap

You can also do like this

$arr_view_data['var1'] = $value1;
$arr_view_data['var2'] = $value2;
$arr_view_data['var3'] = $value3;

return view('your_viewname_here',$arr_view_data);

And you access this variable to view as $var1,$var2,$var3

EDIT:

To Be Clear: If the order of your #includes matters and it is not part of your design pattern (read: you don't know why), then you need to rethink your design. Most likely, this just means you need to add the #include to the header file causing problems.

At this point, I have little interest in discussing/defending the merits of the example but will leave it up as it illustrates some nuances in the compilation process and why they result in errors.

END EDIT

You need to #include the stdint.h BEFORE you #include any other library interfaces that need it.

Example:

My LCD library uses uint8_t types. I wrote my library with an interface (Display.h) and an implementation (Display.c)

In display.c, I have the following includes.

#include <stdint.h>
#include <string.h>
#include <avr/io.h>
#include <Display.h>
#include <GlobalTime.h>

And this works.

However, if I re-arrange them like so:

#include <string.h>
#include <avr/io.h>
#include <Display.h>
#include <GlobalTime.h>
#include <stdint.h>

I get the error you describe. This is because Display.h needs things from stdint.h but can't access it because that information is compiled AFTER Display.h is compiled.

So move stdint.h above any library that need it and you shouldn't get the error anymore.

I don't think everyone is rabidly against it. In languages without static types, it's pretty useful. I definitely prefer it when it's used to give information that is not already in the type. Like in C, char * szName says that the variable will refer to a null terminated string -- that's not implicit in char* -- of course, a typedef would also help.

Joel had a great article on using hungarian to tell if a variable was HTML encoded or not:

http://www.joelonsoftware.com/articles/Wrong.html

Anyway, I tend to dislike Hungarian when it's used to impart information I already know.

rather then using the '/' for the call to split, better to use the Path.DirectorySeparatorChar :

like so:

path.split(Path.DirectorySeparatorChar).Last() 

<form (keydown)="someMethod($event)">
     <input type="text">
</form>

someMethod(event:any){
   if(event.keyCode == 13){
      alert('Entered Click Event!');
   }else{
   }
}

I tried this code, to retrieve shared preferences from an activity, and could not get it to work:

        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
    sharedPreferences.getAll();
    Log.d("AddNewRecord", "getAll: " + sharedPreferences.getAll());
    Log.d("AddNewRecord", "Size: " + sharedPreferences.getAll().size());

Every time I tried, my preferences returned 0, even though I have 14 preferences saved by the preference activity. I finally found the answer. I added this to the preferences in the onCreate section.

getPreferenceManager().setSharedPreferencesName("defaultPreferences");

After I added this statement, my saved preferences returned as expected. I hope that this helps someone else who may experience the same issue that I did.

I often have this problem with sequences (as opposed to discrete values). If I have a sequence of ints, and I want to SUM them, when the list is empty I'll receive the error "InvalidOperationException: The null value cannot be assigned to a member with type System.Int32 which is a non-nullable value type.".

I find I can solve this by casting the sequence to a nullable type. SUM and the other aggregate operators don't throw this error if a sequence of nullable types is empty.

So for example something like this

MySum = MyTable.Where(x => x.SomeCondtion).Sum(x => x.AnIntegerValue);

becomes

MySum = MyTable.Where(x => x.SomeCondtion).Sum(x => (int?) x.AnIntegerValue);

The second one will return 0 when no rows match the where clause. (the first one throws an exception when no rows match).

$('#mainn').text(function (_,txt) {
    return txt.slice(0, -1);
});

An instance variable is a variable that is a member of an instance of a class (i.e., associated with something created with a new), whereas a class variable is a member of the class itself.

Every instance of a class will have its own copy of an instance variable, whereas there is only one of each static (or class) variable, associated with the class itself.

What’s the difference between a class variable and an instance variable?

This test class illustrates the difference:

public class Test {
   
    public static String classVariable = "I am associated with the class";
    public String instanceVariable = "I am associated with the instance";
    
    public void setText(String string){
        this.instanceVariable = string;
    }
    
    public static void setClassText(String string){
        classVariable = string;
    }
    
    public static void main(String[] args) {
        Test test1 = new Test();
        Test test2 = new Test();
        
        // Change test1's instance variable
        test1.setText("Changed");
        System.out.println(test1.instanceVariable); // Prints "Changed"
        // test2 is unaffected
        System.out.println(test2.instanceVariable); // Prints "I am associated with the instance"
        
        // Change class variable (associated with the class itself)
        Test.setClassText("Changed class text");
        System.out.println(Test.classVariable); // Prints "Changed class text"
        
        // Can access static fields through an instance, but there still is only one
        // (not best practice to access static variables through instance)
        System.out.println(test1.classVariable); // Prints "Changed class text"
        System.out.println(test2.classVariable); // Prints "Changed class text"
    }
}
