i had the same error while working with hibernate, i had added below dependency in my pom.xml that solved the problem

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.10</version>

First, in Python, if your code is CPU-bound, multithreading won't help, because only one thread can hold the Global Interpreter Lock, and therefore run Python code, at a time. So, you need to use processes, not threads.

This is not true if your operation "takes forever to return" because it's IO-bound—that is, waiting on the network or disk copies or the like. I'll come back to that later.

Next, the way to process 5 or 10 or 100 items at once is to create a pool of 5 or 10 or 100 workers, and put the items into a queue that the workers service. Fortunately, the stdlib multiprocessing and concurrent.futures libraries both wraps up most of the details for you.

The former is more powerful and flexible for traditional programming; the latter is simpler if you need to compose future-waiting; for trivial cases, it really doesn't matter which you choose. (In this case, the most obvious implementation with each takes 3 lines with futures, 4 lines with multiprocessing.)

If you're using 2.6-2.7 or 3.0-3.1, futures isn't built in, but you can install it from PyPI (pip install futures).

Finally, it's usually a lot simpler to parallelize things if you can turn the entire loop iteration into a function call (something you could, e.g., pass to map), so let's do that first:

def try_my_operation(item):
    try:
        api.my_operation(item)
    except:
        print('error with item')

Putting it all together:

executor = concurrent.futures.ProcessPoolExecutor(10)
futures = [executor.submit(try_my_operation, item) for item in items]
concurrent.futures.wait(futures)

If you have lots of relatively small jobs, the overhead of multiprocessing might swamp the gains. The way to solve that is to batch up the work into larger jobs. For example (using grouper from the itertools recipes, which you can copy and paste into your code, or get from the more-itertools project on PyPI):

def try_multiple_operations(items):
    for item in items:
        try:
            api.my_operation(item)
        except:
            print('error with item')

executor = concurrent.futures.ProcessPoolExecutor(10)
futures = [executor.submit(try_multiple_operations, group) 
           for group in grouper(5, items)]
concurrent.futures.wait(futures)

Finally, what if your code is IO bound? Then threads are just as good as processes, and with less overhead (and fewer limitations, but those limitations usually won't affect you in cases like this). Sometimes that "less overhead" is enough to mean you don't need batching with threads, but you do with processes, which is a nice win.

So, how do you use threads instead of processes? Just change ProcessPoolExecutor to ThreadPoolExecutor.

If you're not sure whether your code is CPU-bound or IO-bound, just try it both ways.

Can I do this for multiple functions in my python script? For example, if I had another for loop elsewhere in the code that I wanted to parallelize. Is it possible to do two multi threaded functions in the same script?

Yes. In fact, there are two different ways to do it.

First, you can share the same (thread or process) executor and use it from multiple places with no problem. The whole point of tasks and futures is that they're self-contained; you don't care where they run, just that you queue them up and eventually get the answer back.

Alternatively, you can have two executors in the same program with no problem. This has a performance cost—if you're using both executors at the same time, you'll end up trying to run (for example) 16 busy threads on 8 cores, which means there's going to be some context switching. But sometimes it's worth doing because, say, the two executors are rarely busy at the same time, and it makes your code a lot simpler. Or maybe one executor is running very large tasks that can take a while to complete, and the other is running very small tasks that need to complete as quickly as possible, because responsiveness is more important than throughput for part of your program.

If you don't know which is appropriate for your program, usually it's the first.

The other answers are correct. But I want to add that it is a relic of the time when people were first learning CSS, and abused float to do all their layout. float is meant to do stuff like float images next to long runs of text, but lots of people used it as their primary layout mechanism. Since it wasn't really meant for that, you need hacks like "clearfix" to make it work.

These days display: inline-block is a solid alternative (except for IE6 and IE7), although more modern browsers are coming with even more useful layout mechanisms under names like flexbox, grid layout, etc.

Ideally the email content should be about 550px wide to fit within most email clients preview window. If you know for sure your target market can view bigger then you can design bigger. Loads of email examples over on http://www.beautiful-email-newsletters.com/

Try this:

<?php
    echo <<<HTML

    Your HTML tags here

HTML;
?>

Try the line-height property.

For example, 12px font-size and 4px distant from the bottom and upper lines:

line-height: 20px; /* 4px +12px + 4px */

Or with em units

line-height: 1.7em; /* 1em = 12px in this case. 20/12 == 1.666666  */

I'd make both the input and label elements display: block , and then split the name label & input, and the email label & input into div's and float them next to each other.

input, label {_x000D_
    display:block;_x000D_
}

<form name="message" method="post">_x000D_
    <section>_x000D_
_x000D_
  <div style="float:left;margin-right:20px;">_x000D_
    <label for="name">Name</label>_x000D_
    <input id="name" type="text" value="" name="name">_x000D_
  </div>_x000D_
_x000D_
  <div style="float:left;">_x000D_
    <label for="email">Email</label>_x000D_
    <input id="email" type="text" value="" name="email">_x000D_
  </div>_x000D_
_x000D_
  <br style="clear:both;" />_x000D_
_x000D_
    </section>_x000D_
_x000D_
    <section>_x000D_

    <label for="subject">Subject</label>_x000D_
    <input id="subject" type="text" value="" name="subject">_x000D_
    <label for="message">Message</label>_x000D_
    <input id="message" type="text" value="" name="message">_x000D_
_x000D_
    </section>_x000D_
</form>

If I have to do this, I will simply create a schema sql of current db, then drop & create db, then load db with schema sql.

Below are the steps involved:

1) Create Schema dump of database (--schema-only)

pg_dump mydb -s > schema.sql

2) Drop database

drop database mydb;

3) Create Database

create database mydb;

4) Import Schema

psql mydb < schema.sql

Prefix the call with Module2 (ex. Module2.IDLE). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.

ps aux | grep node
kill -9 [PID] (provided by above command)

Description:

1. ps will give the process status, aux provide the list of a: all users processes, u: user own processes, x: all other processes not attached to terminal.
2. pipe symbol: | will pass the result of ps aux to manipulate further.
3. grep will search the string provided(node in our case) from the list provided by ps aux.

You have to add this line just before loop

    MyFile = Dir
Loop

In terms of C# language, the following may not make much sense. And this is not a direct answer to the question. But following is what I did in one of my business scenarios.

char? myCharFromUI = Convert.ToChar(" ");
string myStringForDatabaseInsert = myCharFromUI.ToString().Trim();
if (String.IsNullOrEmpty(myStringForDatabaseInsert.Trim()))
{
    Console.Write("Success");
}

The null and white space had different business flows in my project. While inserting into database, I need to insert empty string to the database if it is white space.

For errors with Microsoft.WebApplications.targets, you can:

1. Install Visual Studio 2010 (or the same version as in development machine) in your TFS server.
2. Copy the “Microsoft.WebApplication.targets” from development machine file to TFS build machine.

Here's the post.

If you are using Chrome, then debug with the console. Press SHIFT+CTRL+j to get the console on screen.

Trust me, it helps a lot.

This is overcomplicated. An easier version of:

var rl = require('readline');
rl.createInterface... etc

would be to use

var rl = require('readline-sync');

then it will wait when you use

rl.question('string');

then it is easier to repeat. for example:

var rl = require('readline-sync');
for(let i=0;i<10;i++) {
    var ans = rl.question('What\'s your favourite food?');
    console.log('I like '+ans+' too!');
}

import urllib.request
import os

img_url = "https://betanews.com/wp-content/uploads/2017/09/firefox-logo.jpg"
img_name = os.path.basename(img_url)
urllib.request.urlretrieve(img_url,img_name)

You could use this: http://code.google.com/p/java2word

I implemented this API called Java2Word. with a few lines of code, you can generate one Microsoft Word Document.

Eg.:

IDocument myDoc = new Document2004();
myDoc.getBody().addEle(new Heading1("Heading01"));
myDoc.getBody().addEle(new Paragraph("This is a paragraph...")

There is some examples how to use. Basically you will need one jar file. Let me know if you need any further information how to set it up.

OK! I know that jQuery is loading. I know that jQuery.textshadow.js is loading. I can find both of the scripts in Developer Tools.

The weird part: this code is working in the content area but not in the banner. Even with a dedicated fixIE.css. AND it works when I put the css inline. (That, of course, messes up FireFox.)

I have even put in a conditional IE span around the text field in the banner with no luck.

I found no difference and had the same errors in both jquery-1.4.2.min.js and jquery-1.2.6.min.js. jquery.textshadow.js was downloaded from the jQuery site while trying to find a solution to this problem.

This is not posted to the Website

No, AFAIK, it's not possible to do it portably.

There's no defined "first" record anyway - on different SQL engines it's perfectly possible that "SELECT * FROM table" might return the results in a different order each time.

I had the same issue, to resolve it I added the following line to my.ini

innodb_force_recovery = 1

Emit cheatsheet

io.on('connect', onConnect);

function onConnect(socket){

  // sending to the client
  socket.emit('hello', 'can you hear me?', 1, 2, 'abc');

  // sending to all clients except sender
  socket.broadcast.emit('broadcast', 'hello friends!');

  // sending to all clients in 'game' room except sender
  socket.to('game').emit('nice game', "let's play a game");

  // sending to all clients in 'game1' and/or in 'game2' room, except sender
  socket.to('game1').to('game2').emit('nice game', "let's play a game (too)");

  // sending to all clients in 'game' room, including sender
  io.in('game').emit('big-announcement', 'the game will start soon');

  // sending to all clients in namespace 'myNamespace', including sender
  io.of('myNamespace').emit('bigger-announcement', 'the tournament will start soon');

  // sending to individual socketid (private message)
  socket.to(<socketid>).emit('hey', 'I just met you');

  // sending with acknowledgement
  socket.emit('question', 'do you think so?', function (answer) {});

  // sending without compression
  socket.compress(false).emit('uncompressed', "that's rough");

  // sending a message that might be dropped if the client is not ready to receive messages
  socket.volatile.emit('maybe', 'do you really need it?');

  // sending to all clients on this node (when using multiple nodes)
  io.local.emit('hi', 'my lovely babies');

};

The most simple way is to use pack() method before visualizing the JFrame object. here is an example:

myFrame frm = new myFrame();
frm.pack();
frm.setVisible(true);

I've worked with a lot of CSV files in my time. I'd like to add the advice:

1 - Depending on the source (Excel, etc), commas or tabs may be embedded in a field. Usually, the rule is that they will be 'protected' because the field will be double-quote delimited, as in "Boston, MA 02346".

2 - Some sources will not double-quote delimit all text fields. Other sources will. Others will delimit all fields, even numerics.

3 - Fields containing double-quotes usually get the embedded double quotes doubled up (and the field itself delimited with double quotes, as in "George ""Babe"" Ruth".

4 - Some sources will embed CR/LFs (Excel is one of these!). Sometimes it'll be just a CR. The field will usually be double-quote delimited, but this situation is very difficult to handle.

Below code should work for \n is required to be displayed on the string.

import string

our_str = 'The String is \\n, \\n and \\n!'
new_str = string.replace(our_str, '/\\n', '/\n', 1)
print(new_str)

The font tag has been deprecated for some time now.

That being said, the reason why both of your tables display with the same font size is that the 'size' attribute only accepts values ranging from 1 - 7. The smallest size is 1. The largest size is 7. The default size is 3. Any values larger than 7 will just display the same as if you had used 7, because 7 is the maximum value allowed.

And as @Alex H said, you should be using CSS for this.

The reason you cannot cast List<String> to List<Object> is that it would allow you to violate the constraints of the List<String>.

Think about the following scenario: If I have a List<String>, it is supposed to only contain objects of type String. (Which is a final class)

If I can cast that to a List<Object>, then that allows me to add Object to that list, thus violating the original contract of List<String>.

Thus, in general, if class C inherits from class P, you cannot say that GenericType<C> also inherits from GenericType<P>.

N.B. I already commented on this in a previous answer but wanted to expand on it.

:nth-last-child(-n+2) should do the trick

Given this example url:

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

$_SERVER['REQUEST_URI'] will give you:

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

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

bogus

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

I think you are looking for ToText(CCur(@Price}/{ValuationReport.YestPrice}*100-100))

You can use CCur to convert numbers or string to Curency formats. CCur(number) or CCur(string)

I think this may be what you are looking for,

Replace (ToText(CCur({field})),"$" , "") that will give the parentheses for negative numbers

It is a little hacky, but I'm not sure CR is very kind in the ways of formatting

Here is how I do it by using HashSet

        HashSet<String> hs = new HashSet<string>(new String[] { "Pluto", "Earth", "Neptune" });
        String[] arr =
        {
            "Pluto",
            "Earth",
            "Neptune",
            "Jupiter",
            "Saturn",
            "Mercury",
            "Pluto",
            "Earth",
            "Neptune",
            "Jupiter",
            "Saturn",
            "Mercury",
            // etc.
        };
        ICollection<String> coll = arr;

        String[] arrStrFiltered = coll.Where(str => hs.Contains(str)).ToArray();

HashSet is basically almost to O(1) so your complexity remains O(n).

You can either use the period operator and concatenate a string to it (and it will be type casted to a string):

$integer = 93;
$stringedInt = $integer . "";

Or, more correctly, you can just type cast the integer to a string:

$integer = 93;
$stringedInt = (string) $integer;

If you're like me, using Autolayout and not getting the keyboard when running the App on a simulator. This might be because Apple make you use the keyboard of you're computer as first Keyboard.

To make the keyboard from the device appear :

shift + cmd + K

Sounds stupid but I would have loved to find this answer 3 hours ago :)

I know this is an old question, but rather than adding the snapin which is apparently unsupported, I just looked at the EMS shortcut properties and copied those commands.

The full shortcut target is:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noexit -command ". 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto"

So I put the following at the start of my script and it seemed to function as expected:

. 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'
Connect-ExchangeServer -auto

Notes:

• Has to be run in 64bit PS
• This was tested on a server with just the Management Tools installed. It automatically connected to our existing Exchange infrastructure.
• No extensive testing has been done, so I do not know if this method is viable. I will edit this post if I run into any issues.

FYI: this github project shows you how to list 90% of variables across all hosts. I find it more globally useful than single host commands. The README includes instructions for building a simple inventory report. It's even more valuable to run this at the end of a playbook to see all the Facts. To also debug Task behaviour use register:

The result is missing a few items: - included YAML file variables - extra-vars - a number of the Ansible internal vars described here: Ansible Behavioural Params

For future readers, I found that I experienced a problem and was getting an unrecognised selector sent to instance error that was caused by marking the target func as private.

The func MUST be publicly visible to be called by an object with a reference to a selector.

If you have to use Relational DataBase to organize tree data structure then Postgresql has cool ltree module that provides data type for representing labels of data stored in a hierarchical tree-like structure. You can get the idea from there.(For more information see: http://www.postgresql.org/docs/9.0/static/ltree.html)

In common LDAP is used to organize records in hierarchical structure.

Using setInterval:

setInterval(function() {
    // your code goes here...
}, 60 * 1000); // 60 * 1000 milsec

The function returns an id you can clear your interval with clearInterval:

var timerID = setInterval(function() {
    // your code goes here...
}, 60 * 1000); 

clearInterval(timerID); // The setInterval it cleared and doesn't run anymore.

A "sister" function is setTimeout/clearTimeout look them up.

If you want to run a function on page init and then 60 seconds after, 120 sec after, ...:

function fn60sec() {
    // runs every 60 sec and runs on init.
}
fn60sec();
setInterval(fn60sec, 60*1000);

If class has only one empty constructor (like Activity or Fragment etc, android classes):

Class<?> myClass = Class.forName("com.example.MyClass");    
Constructor<?> constructor = myClass.getConstructors()[0];

You can use .offset() to get the offset compared to the document element and then use the scrollTop property of the window element to find how far down the page the user has scrolled:

var scrollTop     = $(window).scrollTop(),
    elementOffset = $('#my-element').offset().top,
    distance      = (elementOffset - scrollTop);

The distance variable now holds the distance from the top of the #my-element element and the top-fold.

Here is a demo: http://jsfiddle.net/Rxs2m/

Note that negative values mean that the element is above the top-fold.

First go to the directory where your python script is present by using-

cd path/to/directory

then simply do:

python file_name.py

This should do what you're looking for:

function clean($string) {
   $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.

   return preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.
}

Usage:

echo clean('a|"bc!@£de^&$f g');

Will output: abcdef-g

Edit:

Hey, just a quick question, how can I prevent multiple hyphens from being next to each other? and have them replaced with just 1?

function clean($string) {
   $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.
   $string = preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.

   return preg_replace('/-+/', '-', $string); // Replaces multiple hyphens with single one.
}

I've briefly covered a simple way to do this with Google Spreadsheets (importHTML) and in Python (Pandas read_html and to_csv) as well as an example Python script in my SO answer here: https://stackoverflow.com/a/28083469/1588795.

This solved my problem of browser detection, I hope, this will also help you. Thank you.

For checking the empty string in shell

Element, Pseudo Element: d = 1 – (0,0,0,1)
Class, Pseudo class, Attribute: c = 1 – (0,0,1,0)
Id: b = 1 – (0,1,0,0)
Inline Style: a = 1 – (1,0,0,0)

Inline css ( html style attribute ) overrides css rules in style tag and css file

A more specific selector takes precedence over a less specific one.

Rules that appear later in the code override earlier rules if both have the same specificity.

Queue is an interface in java, you can not do that.

Instead you have two options:

option1:

Queue<Integer> Q = new LinkedList<>();

option2:

Queue<Integer> Q = new ArrayDeque<>();

I recommend using option2 as it is bit faster than the other

I want to extend this topic/answers with the following. As someone mentioned, this auto-generated AssemblyInfo can be an obstacle for the external tools. In my case, using FinalBuilder, I had an issue that AssemblyInfo wasn't getting updated by build action. Apparently, FinalBuilder relies on ~proj file to find location of the AssemblyInfo. I thought, it was looking anywhere under project folder. No. So, changing this

<PropertyGroup>
   <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
</PropertyGroup> 

did only half the job, it allowed custom assembly info if built by VS IDE/MS Build. But I needed FinalBuilder do it too without manual manipulations to assembly info file. I needed to satisfy all programs, MSBuild/VS and FinalBuilder.

I solved this by adding an entry to the existing ItemGroup

<ItemGroup>
   <Compile Remove="Common\**" />
   <Content Remove="Common\**" />
   <EmbeddedResource Remove="Common\**" />
   <None Remove="Common\**" />
   <!-- new added item -->
   <None Include="Properties\AssemblyInfo.cs" />
</ItemGroup>

Now, having this item, FinalBuilder finds location of AssemblyInfo and modifies the file. While action None allows MSBuild/DevEnv ignore this entry and no longer report an error based on Compile action that usually comes with Assembly Info entry in proj files.

C:\Program Files\dotnet\sdk\2.0.2\Sdks\Microsoft.NET.Sdk\build\Microsoft.NET.Sdk.DefaultItems.targets(263,5): error : Duplicate 'Compile' items were included. The .NET SDK includes 'Compile' items from your project directory by default. You can either remove these items from your project file, or set the 'EnableDefaultCompileItems' property to 'false' if you want to explicitly include them in your project file. For more information, see https://aka.ms/sdkimplicititems. The duplicate items were: 'AssemblyInfo.cs'

In Python 2.7 with iPython:

>>> import os
>>> os.getenv??
Signature: os.getenv(key, default=None)
Source:
def getenv(key, default=None):
    """Get an environment variable, return None if it doesn't exist.
    The optional second argument can specify an alternate default."""
    return environ.get(key, default)
File:      ~/venv/lib/python2.7/os.py
Type:      function

So we can conclude os.getenv is just a simple wrapper around os.environ.get.

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

You need both a value and a field to assign it to. The value is TableField + 1, so the assignment is:

SET TableField = TableField + 1

Just to add a bit of extra info over the right solution. Be aware that you'll need this class org.apache.catalina.filters.CorsFilter. So in order to have it, if your tomcat is not 7.0.41 or higher, download 'tomcat-catalina.7.0.41.jar' or higher ( you can do it from http://mvnrepository.com/artifact/org.apache.tomcat/tomcat-catalina ) and put it in the 'lib' folder inside Tomcat installation folders. I actually used 7.0.42 Hope it helps!

very interesting question, but this "hasnext" design had been put into leetcode: https://leetcode.com/problems/iterator-for-combination/

here is my implementation:

class CombinationIterator:

def __init__(self, characters: str, combinationLength: int):
    from itertools import combinations
    from collections import deque
    self.iter = combinations(characters, combinationLength)
    self.res = deque()


def next(self) -> str:
    if len(self.res) == 0:
        return ''.join(next(self.iter))
    else:
        return ''.join(self.res.pop())


def hasNext(self) -> bool:
    try:
        self.res.insert(0, next(self.iter))
        return True
    except:
        return len(self.res) > 0

Dictionary data type has a method called dict_name.pop(item) and this can be used to delete a key:value pair from a dictionary.

a={9:4,2:3,4:2,1:3}
a.pop(9)
print(a)

This will give the output as:

{2: 3, 4: 2, 1: 3}

This way you can delete an item from a dictionary in one line.

You can use the hashlib library for Python. The shake_128 and shake_256 algorithms provide variable length hashes. Here's some working code (Python3):

import hashlib
>>> my_string = 'hello shake'
>>> hashlib.shake_256(my_string.encode()).hexdigest(5)
'34177f6a0a'

Notice that with a length parameter x (5 in example) the function returns a hash value of length 2x.

You could do this:

SELECT * FROM table WHERE cast(YOUR_INTEGER_VALUE as varchar) = 'string of numbers'

Some 2+ years after I asked this question I'd like to explain it the way I'd want it explained back when I was still a complete newb and would be most beneficial to people who want to understand the process.

First of all, forget the "11111111" example value, which is not really all that suited for the visual explanation of the process. So let the initial value be 10111011 (187 decimal) which will be a little more illustrative of the process.

1 - how to read a 3 bit value starting from the second bit:

    ___  <- those 3 bits
10111011 

The value is 101, or 5 in decimal, there are 2 possible ways to get it:

• mask and shift

In this approach, the needed bits are first masked with the value 00001110 (14 decimal) after which it is shifted in place:

    ___
10111011 AND
00001110 =
00001010 >> 1 =
     ___
00000101

The expression for this would be: (value & 14) >> 1

• shift and mask

This approach is similar, but the order of operations is reversed, meaning the original value is shifted and then masked with 00000111 (7) to only leave the last 3 bits:

    ___
10111011 >> 1
     ___
01011101 AND
00000111
00000101

The expression for this would be: (value >> 1) & 7

Both approaches involve the same amount of complexity, and therefore will not differ in performance.

2 - how to write a 3 bit value starting from the second bit:

In this case, the initial value is known, and when this is the case in code, you may be able to come up with a way to set the known value to another known value which uses less operations, but in reality this is rarely the case, most of the time the code will know neither the initial value, nor the one which is to be written.

This means that in order for the new value to be successfully "spliced" into byte, the target bits must be set to zero, after which the shifted value is "spliced" in place, which is the first step:

    ___ 
10111011 AND
11110001 (241) =
10110001 (masked original value)

The second step is to shift the value we want to write in the 3 bits, say we want to change that from 101 (5) to 110 (6)

     ___
00000110 << 1 =
    ___
00001100 (shifted "splice" value)

The third and final step is to splice the masked original value with the shifted "splice" value:

10110001 OR
00001100 =
    ___
10111101

The expression for the whole process would be: (value & 241) | (6 << 1)

Bonus - how to generate the read and write masks:

Naturally, using a binary to decimal converter is far from elegant, especially in the case of 32 and 64 bit containers - decimal values get crazy big. It is possible to easily generate the masks with expressions, which the compiler can efficiently resolve during compilation:

• read mask for "mask and shift": ((1 << fieldLength) - 1) << (fieldIndex - 1), assuming that the index at the first bit is 1 (not zero)
• read mask for "shift and mask": (1 << fieldLength) - 1 (index does not play a role here since it is always shifted to the first bit
• write mask : just invert the "mask and shift" mask expression with the ~ operator

How does it work (with the 3bit field beginning at the second bit from the examples above)?

00000001 << 3
00001000  - 1
00000111 << 1
00001110  ~ (read mask)
11110001    (write mask)

The same examples apply to wider integers and arbitrary bit width and position of the fields, with the shift and mask values varying accordingly.

Also note that the examples assume unsigned integer, which is what you want to use in order to use integers as portable bit-field alternative (regular bit-fields are in no way guaranteed by the standard to be portable), both left and right shift insert a padding 0, which is not the case with right shifting a signed integer.

Even easier:

Using this set of macros (but only in C++ since it relies on the generation of member functions):

#define GETMASK(index, size) ((((size_t)1 << (size)) - 1) << (index))
#define READFROM(data, index, size) (((data) & GETMASK((index), (size))) >> (index))
#define WRITETO(data, index, size, value) ((data) = (((data) & (~GETMASK((index), (size)))) | (((value) << (index)) & (GETMASK((index), (size))))))
#define FIELD(data, name, index, size) \
  inline decltype(data) name() const { return READFROM(data, index, size); } \
  inline void set_##name(decltype(data) value) { WRITETO(data, index, size, value); }

You could go for something as simple as:

struct A {
  uint bitData;
  FIELD(bitData, one, 0, 1)
  FIELD(bitData, two, 1, 2)
};

And have the bit fields implemented as properties you can easily access:

A a;
a.set_two(3);
cout << a.two();

Replace decltype with gcc's typeof pre-C++11.

{path: 'users', redirectTo: 'users/', pathMatch: 'full'},
{path: 'users/:userId', component: UserComponent}

This way the component isn't re-rendered when the parameter is added.

User data is very important for a good developer, so don't ask again and again for same data, use some logic to correct some basic error in data.

Before validation of Email: First you have to remove all illegal characters from email.

//This will Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

after that validate your email address using this filter_var() function.

filter_var($email, FILTER_VALIDATE_EMAIL)) // To Validate the email

For e.g.

<?php
$email = "[email protected]";

// Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

// Validate email
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo $email." is a valid email address";
} else {
    echo $email." is not a valid email address";
}
?>

If you don't have access to php.ini, adding this code (after your $ch = curl_init(); line) works for me:

$certificate_location = "C:\Program Files (x86)\EasyPHP-Devserver-16.1\ca-bundle.crt"; // modify this line accordingly (may need to be absolute)
curl_setopt($ch, CURLOPT_CAINFO, $certificate_location);
curl_setopt($ch, CURLOPT_CAPATH, $certificate_location);

Then, you will just need to download ca-bundle.crt and save it to location you specified in $certificate_location.

One other possible implementation, more cumbersome than the .bind() solution, but one that helps to make the point that expect() requires a function that provides a this context to the covered function, you can use a call(), e.g.,

expect(function() {model.get.call(model, 'z');}).to.throw('...');

TS has many utility methods for arrays which are available via the prototype of Arrays. There are multiple which can achieve this goal but the two most convenient for this purpose are:

1. Array.indexOf() Takes any value as an argument and then returns the first index at which a given element can be found in the array, or -1 if it is not present.
2. Array.includes() Takes any value as an argument and then determines whether an array includes a this value. The method returning true if the value is found, otherwise false.

Example:

const channelArray: string[] = ['one', 'two', 'three'];

console.log(channelArray.indexOf('three'));      // 2
console.log(channelArray.indexOf('three') > -1); // true
console.log(channelArray.indexOf('four') > -1);  // false
console.log(channelArray.includes('three'));     // true

1. I think its better you read data of text file in DataSet

2. Try out SqlBulkCopy - Bulk Insert into SQL from C# App

   // connect to SQL
   using (SqlConnection connection = new SqlConnection(connString))
   {
       // make sure to enable triggers
       // more on triggers in next post
       SqlBulkCopy bulkCopy = new SqlBulkCopy(
           connection, 
           SqlBulkCopyOptions.TableLock | 
           SqlBulkCopyOptions.FireTriggers | 
           SqlBulkCopyOptions.UseInternalTransaction,
           null
           );
   
       // set the destination table name
       bulkCopy.DestinationTableName = this.tableName;
       connection.Open();
   
       // write the data in the "dataTable"
       bulkCopy.WriteToServer(dataTable);
       connection.Close();
   }
   // reset
   this.dataTable.Clear();
   

or

after doing step 1 at the top

2. Create XML from DataSet
3. Pass XML to database and do bulk insert

you can check this article for detail : Bulk Insertion of Data Using C# DataTable and SQL server OpenXML function

But its not tested with 2 million record, it will do but consume memory on machine as you have to load 2 million record and insert it.

Try this

ALTER DATABASE XXXX  SET RECOVERY SIMPLE

use XXXX

declare @log_File_Name varchar(200) 

select @log_File_Name  = name from sysfiles where filename like '%LDF'

declare @i int = FILE_IDEX ( @log_File_Name)

dbcc shrinkfile ( @i , 50) 

It evaluates at runtime, so you can switch the type like you can in JavaScript to whatever you want. This is legit:

dynamic i = 12;
i = "text";

And so you can change the type as you need. Use it as a last resort; it i s beneficial, but I heard a lot goes on under the scenes in terms of generated IL and that can come at a performance price.

  <script type="text/javascript">
  jQuery(document).ready(function(){
         setTimeout(PopUp(),5000); // invoke Popup function after 5 seconds 
  });
   </script>

IE has some bug with the scrollbars. So if you want either of the two, you must include the following to hide the horizontal scrollbar:

overflow-x: hidden;
overflow-y:scroll;

and to hide vertical:

overflow-y: hidden;
overflow-x: scroll;

here you go.

<img src="https://i.imgur.com/7KpCS0Y.jpg" onclick="window.open(this.src)">

you can declare an empty array like below

String[] arr = new String[]{}; // declare an empty array
String[] arr2 = {"A", "B"}; // declare and assign values to an array
arr = arr2; // assign valued array to empty array

you can't assign values to above empty array like below

arr[0] = "A"; // you can't do this

use:

$scope.users.length;

Instead of:

$scope.users.lenght;

And next time "spell-check" your code.

It also works without jQuery if you do the following changes:

1. Add type="button" to the edit button in order not to trigger submission of the form.

2. Change the name of your function from change() to anything else.

3. Don't use hidden="hidden", use CSS instead: style="display: none;".

The following code works for me:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="STYLESHEET" type="text/css" href="dba_style/buttons.css" />
<title>Untitled Document</title>
</head>
<script type="text/javascript">
function do_change(){
document.getElementById("save").style.display = "block";
document.getElementById("change").style.display = "block";
document.getElementById("cancel").style.display = "block";
}
</script>
<body>
<form name="form1" method="post" action="">
<div class="buttons">

<button type="button" class="regular" name="edit" id="edit" onclick="do_change(); return false;">
    <img src="dba_images/textfield_key.png" alt=""/>
    Edit
</button>

<button type="submit" class="positive" name="save" id="save" style="display:none;">
    <img src="dba_images/apply2.png" alt=""/>
    Save
</button>

<button class="regular" name="change" id="change" style="display:none;">
    <img src="dba_images/textfield_key.png" alt=""/>
    change
</button>

    <button class="negative" name="cancel" id="cancel" style="display:none;">
        <img src="dba_images/cross.png" alt=""/>
        Cancel
    </button>
</div>
</form>
</body>
</html>

You can also use the relatively unused:

    System.Media.SystemSounds.Beep.Play();
    System.Media.SystemSounds.Asterisk.Play();
    System.Media.SystemSounds.Exclamation.Play();
    System.Media.SystemSounds.Question.Play();
    System.Media.SystemSounds.Hand.Play();

Example JS Fiddle

Bullets take the color property of the list:

.listStyle {
    color: red;
}

Note if you want your list text to be a different colour, you have to wrap it in say, a p, for example:

.listStyle p {
    color: black;
}

Example HTML:

<ul class="listStyle">
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
</ul>

According Spring 4 MVC ResponseEntity.BodyBuilder and ResponseEntity Enhancements Example it could be written as:

I surggest using the CopyTo method, so here is my two cent on a solution that is easy to explain and simple. The CopyTo method copies the array to another array at a given index. In this case myArray is copied to newArr starting at index 1 so index 0 in newArr can hold the new value.

"Push" to array online demo

var newValue = 1;
var myArray = new int[5] { 2, 3, 4, 5, 6 };
var newArr = new int[myArray.Length + 1];

myArray.CopyTo(newArr, 1);
newArr[0] = newValue;
    
//debug
for(var i = 0; i < newArr.Length; i++){
    Console.WriteLine(newArr[i].ToString());
}

//output

No need to pass anything in. The function used for addEventListener will automatically have this bound to the current element. Simply use this in your function:

productLineSelect.addEventListener('change', getSelection, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

Here's the fiddle: http://jsfiddle.net/dJ4Wm/

If you want to pass arbitrary data to the function, wrap it in your own anonymous function call:

productLineSelect.addEventListener('change', function() {
    foo('bar');
}, false);

function foo(message) {
    alert(message);
}

Here's the fiddle: http://jsfiddle.net/t4Gun/

If you want to set the value of this manually, you can use the call method to call the function:

var self = this;
productLineSelect.addEventListener('change', function() {
    getSelection.call(self);
    // This'll set the `this` value inside of `getSelection` to `self`
}, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

You need to declare the variables outside the function:

Public iRaw As Integer
Public iColumn As Integer

Function find_results_idle()
    iRaw = 1
    iColumn = 1

Just as an alternative that I could wrap my head around much easier:

data = load_iris()
df = pd.DataFrame(data['data'], columns=data['feature_names'])
df['target'] = data['target']
df.head()

Basically instead of concatenating from the get go, just make a data frame with the matrix of features and then just add the target column with data['whatvername'] and grab the target values from the dataset

If it was installed with plesk (not sure if it's just that, or on the phpmyadmin side: It changes the root user to admin.

try this, in my case the port number for the created object wasn't available so I came up with this

IPEndPoint endPoint;
int port = 1;
while (true)
{
    try
    {
        endPoint = new IPEndPoint(IPAddress.Any, port);
        break;
    }
    catch (SocketException)
    {
         port++;
    }
}

You can also try this. Credits to the original author who has since removed the script

The problem is where you are executing:

rankings[kvp.Key] = rankings[kvp.Key] + 4;

You cannot modify the collection you are iterating through in a foreach loop. A foreach loop requires the loop to be immutable during iteration.

Instead, use a standard 'for' loop or create a new loop that is a copy and iterate through that while updating your original.

From book OCA JAVA SE 7

Just as men and women are fundamentally different (according to John Gray, author of Men Are from Mars, Women Are from Venus), primitive variables and object reference variables differ from each other in multiple ways. The basic difference is that primitive variables store the actual values, whereas reference variables store the addresses of the objects they refer to. Let’s assume that a class Person is already defined. If you create an int variable a, and an object reference variable person, they will store their values in memory as shown in figure 2.13.

int a = 77;
Person person = new Person();

int main(){
    int i=0;
    int a=0;
    for(i;i<5;i++,a++){
        printf("%d %d\n",a,i);
    } 
}

If you are looking for a simple and free alternative to Google Feed API for your rss widget then rss2json.com could be a suitable solution for that.

You may try to see how it works on a sample code from the api documentation below:

google.load("feeds", "1");_x000D_
_x000D_
    function initialize() {_x000D_
      var feed = new google.feeds.Feed("https://news.ycombinator.com/rss");_x000D_
      feed.load(function(result) {_x000D_
        if (!result.error) {_x000D_
          var container = document.getElementById("feed");_x000D_
          for (var i = 0; i < result.feed.entries.length; i++) {_x000D_
            var entry = result.feed.entries[i];_x000D_
            var div = document.createElement("div");_x000D_
            div.appendChild(document.createTextNode(entry.title));_x000D_
            container.appendChild(div);_x000D_
          }_x000D_
        }_x000D_
      });_x000D_

A Custom Laravel Validation Rule will allow developers to provide a custom message with each use case for a better UX experience.

php artisan make:rule IsValidPassword

namespace App\Rules;

use Illuminate\Support\Str;
use Illuminate\Contracts\Validation\Rule;

class isValidPassword implements Rule
{
    /**
     * Determine if the Length Validation Rule passes.
     *
     * @var boolean
     */
    public $lengthPasses = true;

    /**
     * Determine if the Uppercase Validation Rule passes.
     *

     * @return bool
     */
    public function passes($attribute, $value)
    {
        $this->lengthPasses = (Str::length($value) >= 10);
        $this->uppercasePasses = (Str::lower($value) !== $value);
        $this->numericPasses = ((bool) preg_match('/[0-9]/', $value));
        $this->specialCharacterPasses = ((bool) preg_match('/[^A-Za-z0-9]/', $value));

        return ($this->lengthPasses && $this->uppercasePasses && $this->numericPasses && $this->specialCharacterPasses);
    }

    /**

    public function message()
    {
        switch (true) {
            case ! $this->uppercasePasses
                && $this->numericPasses
                && $this->specialCharacterPasses:
                return 'The :attribute must be at least 10 characters and contain at least one uppercase character.';

            case ! $this->numericPasses
                && $this->uppercasePasses
                && $this->specialCharacterPasses:
                return 'The :attribute must be at least 10 characters and contain at least one number.';

            case ! $this->specialCharacterPasses
                && $this->uppercasePasses
                && $this->numericPasses:
                return 'The :attribute must be at least 10 characters and contain at least one special character.';

            case ! $this->uppercasePasses
                && ! $this->numericPasses
                && $this->specialCharacterPasses:
                return 'The :attribute must be at least 10 characters and contain at least one uppercase character and one number.';

            case ! $this->uppercasePasses
                && ! $this->specialCharacterPasses
                && $this->numericPasses:
                return 'The :attribute must be at least 10 characters and contain at least one uppercase character and one special character.';

            case ! $this->uppercasePasses
                && ! $this->numericPasses
                && ! $this->specialCharacterPasses:
                return 'The :attribute must be at least 10 characters and contain at least one uppercase character, one number, and one special character.';

            default:
                return 'The :attribute must be at least 10 characters.';
        }
    }
}

Then on your request validation:

$request->validate([
    'email'    => 'required|string|email:filter',
    'password' => [
        'required',
        'confirmed',
        'string',
        new isValidPassword(),
    ],
]);

Neither submit() nor click() is good enough. However, it works fine if you follow it with an ENTER key:

search_form = driver.find_element_by_id(elem_id)
search_form.send_keys(search_string)
search_form.click()
from selenium.webdriver.common.keys import Keys
search_form.send_keys(Keys.ENTER)

Tested on Mac 10.11, python 2.7.9, Selenium 2.53.5. This runs in parallel, meaning returns after entering the ENTER key, doesn't wait for page to load.

This is how i solve this issue.
The answer of Jonathan Amend on this post helped me a lot.
The example below is simplified.

For more details, the above source code is able to download a file using a JQuery Ajax request (GET, POST, PUT etc). It, also, helps to upload parameters as JSON and to change the content type to application/json (my default).

The html source:

<form method="POST">
    <input type="text" name="startDate"/>
    <input type="text" name="endDate"/>
    <input type="text" name="startDate"/>
    <select name="reportTimeDetail">
        <option value="1">1</option>
    </select>
    <button type="submit"> Submit</button>
</form>  

A simple form with two input text, one select and a button element.

The javascript page source:

<script type="text/javascript" src="JQuery 1.11.0 link"></script>
<script type="text/javascript">
    // File Download on form submition.
    $(document).on("ready", function(){
        $("form button").on("click", function (event) {
            event.stopPropagation(); // Do not propagate the event.

            // Create an object that will manage to download the file.
            new AjaxDownloadFile({
                url: "url that returns a file",
                data: JSON.stringify($("form").serializeObject())
            });

            return false; // Do not submit the form.
        });
    });
</script>  

A simple event on button click. It creates an AjaxDownloadFile object. The AjaxDownloadFile class source is below.

The AjaxDownloadFile class source:

var AjaxDownloadFile = function (configurationSettings) {
    // Standard settings.
    this.settings = {
        // JQuery AJAX default attributes.
        url: "",
        type: "POST",
        headers: {
            "Content-Type": "application/json; charset=UTF-8"
        },
        data: {},
        // Custom events.
        onSuccessStart: function (response, status, xhr, self) {
        },
        onSuccessFinish: function (response, status, xhr, self, filename) {
        },
        onErrorOccured: function (response, status, xhr, self) {
        }
    };
    this.download = function () {
        var self = this;
        $.ajax({
            type: this.settings.type,
            url: this.settings.url,
            headers: this.settings.headers,
            data: this.settings.data,
            success: function (response, status, xhr) {
                // Start custom event.
                self.settings.onSuccessStart(response, status, xhr, self);

                // Check if a filename is existing on the response headers.
                var filename = "";
                var disposition = xhr.getResponseHeader("Content-Disposition");
                if (disposition && disposition.indexOf("attachment") !== -1) {
                    var filenameRegex = /filename[^;=\n]*=(([""]).*?\2|[^;\n]*)/;
                    var matches = filenameRegex.exec(disposition);
                    if (matches != null && matches[1])
                        filename = matches[1].replace(/[""]/g, "");
                }

                var type = xhr.getResponseHeader("Content-Type");
                var blob = new Blob([response], {type: type});

                if (typeof window.navigator.msSaveBlob !== "undefined") {
                    // IE workaround for "HTML7007: One or more blob URLs were revoked by closing the blob for which they were created. These URLs will no longer resolve as the data backing the URL has been freed.
                    window.navigator.msSaveBlob(blob, filename);
                } else {
                    var URL = window.URL || window.webkitURL;
                    var downloadUrl = URL.createObjectURL(blob);

                    if (filename) {
                        // Use HTML5 a[download] attribute to specify filename.
                        var a = document.createElement("a");
                        // Safari doesn"t support this yet.
                        if (typeof a.download === "undefined") {
                            window.location = downloadUrl;
                        } else {
                            a.href = downloadUrl;
                            a.download = filename;
                            document.body.appendChild(a);
                            a.click();
                        }
                    } else {
                        window.location = downloadUrl;
                    }

                    setTimeout(function () {
                        URL.revokeObjectURL(downloadUrl);
                    }, 100); // Cleanup
                }

                // Final custom event.
                self.settings.onSuccessFinish(response, status, xhr, self, filename);
            },
            error: function (response, status, xhr) {
                // Custom event to handle the error.
                self.settings.onErrorOccured(response, status, xhr, self);
            }
        });
    };
    // Constructor.
    {
        // Merge settings.
        $.extend(this.settings, configurationSettings);
        // Make the request.
        this.download();
    }
};

I created this class to added to my JS library. It is reusable. Hope that helps.

For any CSS3-enabled browser you can use an adjacent sibling selector for styling your labels

input:checked + label {
    color: white;
}  

MDN's browser compatibility table says essentially all of the current, popular browsers (Chrome, IE, Firefox, Safari), on both desktop and mobile, are compatible.

Since Android M things have got more complicated. The answer of android.net.URI.getQueryParameter() has a bug which breaks spaces before JellyBean. Apache URLEncodedUtils.parse() worked, but was deprecated in L, and removed in M.

So the best answer now is UrlQuerySanitizer. This has existed since API level 1 and still exists. It also makes you think about the tricky issues like how do you handle special characters, or repeated values.

The simplest code is

UrlQuerySanitizer.ValueSanitizer sanitizer = UrlQuerySanitizer.getAllButNullLegal();
// remember to decide if you want the first or last parameter with the same name
// If you want the first call setPreferFirstRepeatedParameter(true);
sanitizer.parseUrl(url);
String value = sanitizer.getValue("paramName");

If you are happy with the default parsing behavior you can do:

new UrlQuerySanitizer(url).getValue("paramName")

but you should make sure you understand what the default parsing behavor is, as it might not be what you want.

Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json" and format to .json

>>> [i for i in a if 1 in i]

[(1, 2), (1, 4)]

change your

return @str1+'present in the string' ;

to

set @r = @str1+'present in the string' 

If you want to get information about your installed python distributions and don't want to use your cmd console or terminal for it, but rather through python code, you can use the following code (tested with python 3.4):

import pip #needed to use the pip functions
for i in pip.get_installed_distributions(local_only=True):
    print(i)

The pip.get_installed_distributions(local_only=True) function-call returns an iterable and because of the for-loop and the print function the elements contained in the iterable are printed out separated by new line characters (\n). The result will (depending on your installed distributions) look something like this:

cycler 0.9.0
decorator 4.0.4
ipykernel 4.1.0
ipython 4.0.0
ipython-genutils 0.1.0
ipywidgets 4.0.3
Jinja2 2.8
jsonschema 2.5.1
jupyter 1.0.0
jupyter-client 4.1.1
#... and so on...

You can also simply convert a 2D array into hash using:

1.9.3p362 :005 > a= [[1,2],[3,4]]

 => [[1, 2], [3, 4]]

1.9.3p362 :006 > h = Hash[a]

 => {1=>2, 3=>4} 

While building the project on Unix/Linux platform, set Maven options syntax as below. Notice that single qoutation signs, not double qoutation.

export MAVEN_OPTS='-Xmx512m -XX:MaxPermSize=128m'

I like to have a method in my activity called showToast which I can call from anywhere...

public void showToast(final String toast)
{
    runOnUiThread(() -> Toast.makeText(MyActivity.this, toast, Toast.LENGTH_SHORT).show());
}

I then most frequently call it from within MyActivity on any thread like this...

showToast(getString(R.string.MyMessage));

have a look at http://au.php.net/reserved.variables

I think the variable you are looking for is: $_SERVER["DOCUMENT_ROOT"]

SDK wasn't downloaded

so turned on the internet connection and after restarting the Android Studio

it showed a pop up to download 800mb data click on yes and issue gets resolved

Here is an inlineStyle selector filter I wrote that plugs into jQuery.

$("div:inlineStyle(display:block)") // will select all divs with an inline style of display: block set

In your case you could use this like:

$("div:inlineStyle(display:block)").hide();

You can make use of the following code incase you want to check the types of primitive data types.

// Returns 0 if the object type is equal to double
strcmp([myNumber objCType], @encode(double)) 

I have created step by step instructions on how to do this as I also was very confused about how to get this working.

How to make a self extracting archive that runs your setup.exe with 7zip -sfx switch

Here are the steps.

Step 1 - Setup your installation folder

To make this easy create a folder c:\Install. This is where we will copy all the required files.

Step 2 - 7Zip your installers

1. Go to the folder that has your .msi and your setup.exe
2. Select both the .msi and the setup.exe
3. Right-Click and choose 7Zip --> "Add to Archive"
4. Name your archive "Installer.7z" (or a name of your choice)
5. Click Ok
6. You should now have "Installer.7z".
7. Copy this .7z file to your c:\Install directory

Step 3 - Get the 7z-Extra sfx extension module

You need to download 7zSD.sfx

1. Download one of the LZMA packages from here
2. Extract the package and find 7zSD.sfx in the bin folder.
3. Copy the file "7zSD.sfx" to c:\Install

Step 4 - Setup your config.txt

I would recommend using NotePad++ to edit this text file as you will need to encode in UTF-8, the following instructions are using notepad++.

1. Using windows explorer go to c:\Install
2. right-click and choose "New Text File" and name it config.txt
3. right-click and choose "Edit with NotePad++
4. Click the "Encoding Menu" and choose "Encode in UTF-8"

5. Enter something like this:

   ;!@Install@!UTF-8!
   Title="SOFTWARE v1.0.0.0"
   BeginPrompt="Do you want to install SOFTWARE v1.0.0.0?"
   RunProgram="setup.exe"
   ;!@InstallEnd@!
   

Edit this replacing [SOFTWARE v1.0.0.0] with your product name. Notes on the parameters and options for the setup file are here.

CheckPoint

You should now have a folder "c:\Install" with the following 3 files:

1. Installer.7z
2. 7zSD.sfx
3. config.txt

Step 5 - Create the archive

These instructions I found on the web but nowhere did it explain any of the 4 steps above.

1. Open a cmd window, Window + R --> cmd --> press enter

2. In the command window type the following

   cd \
   cd Install
   copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe
   

3. Look in c:\Install and you will now see you have a MyInstaller.exe

You are finished

Run the installer

Double click on MyInstaller.exe and it will prompt with your message. Click OK and the setup.exe will run.

P.S. Note on Automation

Now that you have this working in your c:\Install directory I would create an "Install.bat" file and put the copy script in it.

copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe

Now you can just edit and run the Install.bat every time you need to rebuild a new version of you deployment package.

A good option is Node-supervisor and Node.js Restart on File Change is good article on how to use it, typically:

 npm install supervisor -g

and after migrating to the root of your application use the following

 supervisor app.js

Here's a helper bash function to kill multiple processes by name or port

fkill() {
  for i in $@;do export q=$i;if [[ $i == :* ]];then lsof -i$i|sed -n '1!p';
  else ps aux|grep -i $i|grep -v grep;fi|awk '{print $2}'|\
  xargs -I@ sh -c 'kill -9 @&&printf "X %s->%s\n" $q @';done
}

Usage:

$ fkill [process name] [process port]

Example:

$ fkill someapp :8080 node :3333 :9000

Even if the user and host are the same, they can still be distinguished in ~/.ssh/config. For example, if your configuration looks like this:

Host gitolite-as-alice
  HostName git.company.com
  User git
  IdentityFile /home/whoever/.ssh/id_rsa.alice
  IdentitiesOnly yes

Host gitolite-as-bob
  HostName git.company.com
  User git
  IdentityFile /home/whoever/.ssh/id_dsa.bob
  IdentitiesOnly yes

Then you just use gitolite-as-alice and gitolite-as-bob instead of the hostname in your URL:

git remote add alice git@gitolite-as-alice:whatever.git
git remote add bob git@gitolite-as-bob:whatever.git

Note

You want to include the option IdentitiesOnly yes to prevent the use of default ids. Otherwise, if you also have id files matching the default names, they will get tried first because unlike other config options (which abide by "first in wins") the IdentityFile option appends to the list of identities to try.

W3C CSS Transitions Draft

The completion of a CSS Transition generates a corresponding DOM Event. An event is fired for each property that undergoes a transition. This allows a content developer to perform actions that synchronize with the completion of a transition.

Webkit

To determine when a transition completes, set a JavaScript event listener function for the DOM event that is sent at the end of a transition. The event is an instance of WebKitTransitionEvent, and its type is webkitTransitionEnd.

box.addEventListener( 'webkitTransitionEnd', 
    function( event ) { alert( "Finished transition!" ); }, false );

Mozilla

There is a single event that is fired when transitions complete. In Firefox, the event is transitionend, in Opera, oTransitionEnd, and in WebKit it is webkitTransitionEnd.

Opera

There is one type of transition event available. The oTransitionEnd event occurs at the completion of the transition.

Internet Explorer

The transitionend event occurs at the completion of the transition. If the transition is removed before completion, the event will not fire.

Stack Overflow: How do I normalize CSS3 Transition functions across browsers?

To post JSON, you will need to stringify it. JSON.stringify and set the processData option to false.

$.ajax({
    url: url,
    type: "POST",
    data: JSON.stringify(data),
    processData: false,
    contentType: "application/json; charset=UTF-8",
    complete: callback
});

Use:

((Long) userService.getAttendanceList(currentUser)).intValue();

instead.

The .intValue() method is defined in class Number, which Long extends.

See the Switch Statements Smell:

Typically, similar switch statements are scattered throughout a program. If you add or remove a clause in one switch, you often have to find and repair the others too.

Both Refactoring and Refactoring to Patterns have approaches to resolve this.

If your (pseudo) code looks like:

class RequestHandler {

    public void handleRequest(int action) {
        switch(action) {
            case LOGIN:
                doLogin();
                break;
            case LOGOUT:
                doLogout();
                break;
            case QUERY:
               doQuery();
               break;
        }
    }
}

This code violates the Open Closed Principle and is fragile to every new type of action code that comes along. To remedy this you could introduce a 'Command' object:

interface Command {
    public void execute();
}

class LoginCommand implements Command {
    public void execute() {
        // do what doLogin() used to do
    }
}

class RequestHandler {
    private Map<Integer, Command> commandMap; // injected in, or obtained from a factory
    public void handleRequest(int action) {
        Command command = commandMap.get(action);
        command.execute();
    }
}

If your (pseudo) code looks like:

class House {
    private int state;

    public void enter() {
        switch (state) {
            case INSIDE:
                throw new Exception("Cannot enter. Already inside");
            case OUTSIDE:
                 state = INSIDE;
                 ...
                 break;
         }
    }
    public void exit() {
        switch (state) {
            case INSIDE:
                state = OUTSIDE;
                ...
                break;
            case OUTSIDE:
                throw new Exception("Cannot leave. Already outside");
        }
    }

Then you could introduce a 'State' object.

// Throw exceptions unless the behavior is overriden by subclasses
abstract class HouseState {
    public HouseState enter() {
        throw new Exception("Cannot enter");
    }
    public HouseState leave() {
        throw new Exception("Cannot leave");
    }
}

class Inside extends HouseState {
    public HouseState leave() {
        return new Outside();
    }
}

class Outside extends HouseState {
    public HouseState enter() {
        return new Inside();
    }
}

class House {
    private HouseState state;
    public void enter() {
        this.state = this.state.enter();
    }
    public void leave() {
        this.state = this.state.leave();
    }
}

Hope this helps.

For multibranch pipeline projects, do this in the script console:

def project = Jenkins.instance.getItemByFullName("YourMultibranchPipelineProjectName")    
project.getAllJobs().each{ item ->   
    
    if(item.name == 'jobName'){ // master, develop, feature/......
      
      item.updateNextBuildNumber(#Number);
      item.saveNextBuildNumber();
      
      println('new build: ' + item.getNextBuildNumber())
    }
}

Regarding the Hibernate validator documentation page, you have to define a dependency to a JSR-341 implementation:

<dependency>
   <groupId>org.glassfish</groupId>
   <artifactId>javax.el</artifactId>
   <version>3.0.1-b11</version>
</dependency>

Tweaked version from Techie Delight:

#include <string>
#include <vector>

std::vector<std::string> split(const std::string& str, char delim) {
    std::vector<std::string> strings;
    size_t start;
    size_t end = 0;
    while ((start = str.find_first_not_of(delim, end)) != std::string::npos) {
        end = str.find(delim, start);
        strings.push_back(str.substr(start, end - start));
    }
    return strings;
}

Blat:

blat -to [email protected] -server smtp.example.com -f [email protected] -subject "subject" -body "body"

Supported by SQL Server 2005 and later versions

SELECT CONVERT(VARCHAR(10), GETDATE(), 101) 
       + ' ' + CONVERT(VARCHAR(8), GETDATE(), 108)

* See Microsoft's documentation to understand what the 101 and 108 style codes above mean.

Supported by SQL Server 2012 and later versions

SELECT FORMAT(GETDATE() , 'MM/dd/yyyy HH:mm:ss')

Result

Both of the above methods will return:

I can assure you that raw speed ultimately lies in the non-standard use of Indexes for blazing speed using large tables.

var x = document.getElementsByClassName("class name");
if (x[0]) {
alert('has');
} else {
alert('no has');
}

What about Transactions? They have the ROLLBACK-Feature.

@see https://dev.mysql.com/doc/refman/5.0/en/commit.html

For example:

START TRANSACTION;
SELECT * FROM nicetable WHERE somthing=1;
UPDATE nicetable SET nicefield='VALUE' WHERE somthing=1;
SELECT * FROM nicetable WHERE somthing=1; #check

COMMIT;
# or if you want to reset changes 
ROLLBACK;

SELECT * FROM nicetable WHERE somthing=1; #should be the old value

Answer on question from @rickozoe below:

In general these lines will not be executed as once. In PHP f.e. you would write something like that (perhaps a little bit cleaner, but wanted to answer quick ;-) ):

$MysqlConnection->query('START TRANSACTION;');
$erg = $MysqlConnection->query('UPDATE MyGuests SET lastname='Doe' WHERE id=2;');
if($erg)
    $MysqlConnection->query('COMMIT;');
else
    $MysqlConnection->query('ROLLBACK;');

Another way would be to use MySQL Variables (see https://dev.mysql.com/doc/refman/5.7/en/user-variables.html and https://stackoverflow.com/a/18499823/1416909 ):

# do some stuff that should be conditionally rollbacked later on

SET @v1 := UPDATE MyGuests SET lastname='Doe' WHERE id=2;
IF(v1 < 1) THEN
    ROLLBACK;
ELSE
    COMMIT;
END IF;

But I would suggest to use the language wrappers available in your favorite programming language.

To get the full path use:

readlink -f relative/path/to/file

To get the directory of a file:

dirname relative/path/to/file

You can also combine the two:

dirname $(readlink -f relative/path/to/file)

If readlink -f is not available on your system you can use this^*:

function myreadlink() {
  (
  cd "$(dirname $1)"         # or  cd "${1%/*}"
  echo "$PWD/$(basename $1)" # or  echo "$PWD/${1##*/}"
  )
}

Note that if you only need to move to a directory of a file specified as a relative path, you don't need to know the absolute path, a relative path is perfectly legal, so just use:

cd $(dirname relative/path/to/file)

if you wish to go back (while the script is running) to the original path, use pushd instead of cd, and popd when you are done.

* While myreadlink above is good enough in the context of this question, it has some limitation relative to the readlink tool suggested above. For example it doesn't correctly follow a link to a file with different basename.

The DOM element style "property" is a readonly collection of all the style attributes defined on the element. (The collection property is readonly, not necessarily the items within the collection.)

You would be better off using the className "property" on the elements.

Sometime would be better use name of parent class instead name of table:

# Refers to the current class
self.class.unscoped.where(self.class.primary_key => id).update_all(created _at: timestamp)

For example "Person" base class, subclasses (and database tables) "Client" and "Seller" Instead using:

Client.where(self.class.primary_key => id).update_all(created _at: timestamp)
Seller.where(self.class.primary_key => id).update_all(created _at: timestamp)

You can use object of base class by this way:

person.class.unscoped.where(self.class.primary_key => id).update_all(created _at: timestamp)

This should work.

The background colors are there so you can see how this works. Copy this code to a file and open it in your browser. Try playing around with the CSS a bit and see what happens.

The width: inherit; height: inherit; pulls the width and height from the parent element. This should be the default and is not truly necessary.

Try removing the h1 { ... } CSS block and see what happens. You might notice the layout reacts in an odd way. This is because the h1 element is influencing the layout of its container. You could prevent this by declaring overflow: hidden; on the container or the body.

I'd also suggest you do some reading on the CSS Box Model.

People have recommended MailChimp which is a good vendor for bulk email. If you're looking for a good vendor for transactional email, I might be able to help.

Over the past 6 months, we used four different SMTP vendors with the goal of figuring out which was the best one.

Here's a summary of what we found...

AuthSMTP

• Cheapest around
• No analysis/reporting
• No tracking for opens/clicks
• Had slight hesitation on some sends

Postmark

• Very cheap, but not as cheap as AuthSMTP
• Beautiful cpanel but no tracking on opens/clicks
• Send-level activity tracking so you can open a single email that was sent and look at how it looked and the delivery data.
• Have to use API. Sending by SMTP was recently introduced but it's buggy. For instance, we noticed that quotes (") in the subject line are stripped.
• Cannot send any attachment you want. Must be on approved list of file types and under a certain size. (10 MB I think)
• Requires a set list of from names/addresses.

JangoSMTP

• Expensive in relation to the others – more than 10 times in some cases
• Ugly cpanel but great tracking on opens/clicks with email-level detail
• Had hesitation, at times, when sending. On two occasions, sends took an hour to be delivered
• Requires a set list of from name/addresses.

SendGrid

• Not quite a cheap as AuthSMTP but still very cheap. Many customers can exist on 200 free sends per day.
• Decent cpanel but no in-depth detail on open/click tracking
• Lots of API options. Options (open/click tracking, etc) can be custom defined on an email-by-email basis. Inbound (reply) email can be posted to our HTTP end point.
• Absolutely zero hesitation on sends. Every email sent landed in the inbox almost immediately.
• Can send from any from name/address.

Conclusion

SendGrid was the best with Postmark coming in second place. We never saw any hesitation in send times with either of those two - in some cases we sent several hundred emails at once - and they both have the best ROI, given a solid featureset.

There's a lot of answers here, but no-one seems to have really explained why it is that rand() always generates the same sequence given the same seed - or even what the seed is really doing. So here goes.

The rand() function maintains an internal state. Conceptually, you could think of this as a global variable of some type called rand_state. Each time you call rand(), it does two things. It uses the existing state to calculate a new state, and it uses the new state to calculate a number to return to you:

state_t rand_state = INITIAL_STATE;

state_t calculate_next_state(state_t s);
int calculate_return_value(state_t s);

int rand(void)
{
    rand_state = calculate_next_state(rand_state);
    return calculate_return_value(rand_state);
}

Now you can see that each time you call rand(), it's going to make rand_state move one step along a pre-determined path. The random values you see are just based on where you are along that path, so they're going to follow a pre-determined sequence too.

Now here's where srand() comes in. It lets you jump to a different point on the path:

state_t generate_random_state(unsigned int seed);

void srand(unsigned int seed)
{
    rand_state = generate_random_state(seed);
}

The exact details of state_t, calculate_next_state(), calculate_return_value() and generate_random_state() can vary from platform to platform, but they're usually quite simple.

You can see from this that every time your program starts, rand_state is going to start off at INITIAL_STATE (which is equivalent to generate_random_state(1)) - which is why you always get the same sequence if you don't use srand().

if you want to always use git log in such way you could add git alias by

git config --global alias.log log --oneline

after that git log will print what normally would be printed by git log --oneline

Based on my tests (Win7 64bit, 6GB RAM, Java6), NIO transferFrom is fast only with small files and becomes very slow on larger files. NIO databuffer flip always outperforms standard IO.

• Copying 1000x2MB

  1. NIO (transferFrom) ~2300ms
  2. NIO (direct datababuffer 5000b flip) ~3500ms
  3. Standard IO (buffer 5000b) ~6000ms

• Copying 100x20mb

  1. NIO (direct datababuffer 5000b flip) ~4000ms
  2. NIO (transferFrom) ~5000ms
  3. Standard IO (buffer 5000b) ~6500ms

• Copying 1x1000mb

  1. NIO (direct datababuffer 5000b flip) ~4500s
  2. Standard IO (buffer 5000b) ~7000ms
  3. NIO (transferFrom) ~8000ms

The transferTo() method works on chunks of a file; wasn't intended as a high-level file copy method: How to copy a large file in Windows XP?

I resolved this by changing the following in the app.json file. It appears the capital letter was throwing this error.

From:

{
  "name": "Nameofmyapp",
  ...
}

To:

{
  "name": "nameofmyapp",
  ...
}

This is my sample code for load static variable

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class OnelinkConfig {
    public static int MODULE_CODE;
    public static int DEFAULT_PAGE;
    public static int DEFAULT_SIZE;

    @Autowired
    public void loadOnelinkConfig(@Value("${onelink.config.exception.module.code}") int code,
            @Value("${onelink.config.default.page}") int page, @Value("${onelink.config.default.size}") int size) {
        MODULE_CODE = code;
        DEFAULT_PAGE = page;
        DEFAULT_SIZE = size;
    }
}

Use this code:

UIButton *button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.imageView.frame=CGRectMake(0.0f, 0.0f, 50.0f, 44.0f);///You can replace it with your own dimensions.
    UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(0.0f, 35.0f, 50.0f, 44.0f)];///You can replace it with your own dimensions.
    [button addSubview:label];

// in foo.h
class Foo {
    static const unsigned char* Msg;
};

// in foo.cpp
static const unsigned char Foo_Msg_data[] = {0x00,0x01};
const unsigned char* Foo::Msg = Foo_Msg_data;

inner join with scala

val joinedDataFrame = PersonDf.join(ProfileDf ,"personId")
joinedDataFrame.show

I recommend mongoskin I just created.

var mongo = require('mongoskin');
var db = mongo.db('admin:pass@localhost/mydb?auto_reconnnect');
db.collection('mycollection').find().toArray(function(err, items){
   // do something with items
});

Is mongoskin sync? Nop, it is async.

I found this error while connecting ec2 instance with ssh. and it comes if i write wrong user name.

eg. for ubuntu I need to use ubuntu as user name and for others I need to use ec2-user.

I stole this convienent class from somewhere here at StackOverflow to convert anything streamable to a string:

// make_string
class make_string {
public:
  template <typename T>
  make_string& operator<<( T const & val ) {
    buffer_ << val;
    return *this;
  }
  operator std::string() const {
    return buffer_.str();
  }
private:
  std::ostringstream buffer_;
};

And then you use it as;

string str = make_string() << 6 << 8 << "hello";

Quite nifty!

Also I use this function to convert strings to anything streamable, althrough its not very safe if you try to parse a string not containing a number; (and its not as clever as the last one either)

// parse_string
template <typename RETURN_TYPE, typename STRING_TYPE>
RETURN_TYPE parse_string(const STRING_TYPE& str) {
  std::stringstream buf;
  buf << str;
  RETURN_TYPE val;
  buf >> val;
  return val;
}

Use as:

int x = parse_string<int>("78");

You might also want versions for wstrings.

I faced this issue a number of times in my application.

We can generally handle this with the below 2 approaches.

1. Pass the username and password in url itself

2. You can create an AutoIT Script and call script before opening the url.

Please check the below article in which I have mentioned both ways:
Handle Authentication/Login window in Selenium Webdriver

   $array[0] = 1;
   $array[2] = 2;
   $arrayTxt = implode( ',', $array);
   $sql = "SELECT * FROM table WHERE some_id in ($arrayTxt)"

I edited your plunker to include ABOS's solution.

<body ng-controller="MainCtrl">
    <ul ng-repeat='item in items'>
      <li ng-if='item.color'>The color is {{item.color}}</li>
      <li ng-if='item.shipping !== undefined'>The shipping cost is {{item.shipping}}</li>
    </ul>

Using the code I mentioned...

HTML

<div id="background">
    <img src="img.jpg" class="stretch" alt="" />
</div>

CSS

#background {
    width: 100%; 
    height: 100%; 
    position: fixed; 
    left: 0px; 
    top: 0px; 
    z-index: -1; /* Ensure div tag stays behind content; -999 might work, too. */
}

.stretch {
    width:100%;
    height:100%;
}

That produces the desired effect: only the content will scroll, not the background.

The background image resizes to the browser viewport for any screen size. When the content doesn't fit the browser viewport, and the user needs to scroll the page, the background image remains fixed in the viewport while the content scrolls.

With CSS 3 it seems this would be a lot easier.

If you want user readable data but still detailed, you can use platform.platform()

>>> import platform
>>> platform.platform()
'Linux-3.3.0-8.fc16.x86_64-x86_64-with-fedora-16-Verne'

platform also has some other useful methods:

>>> platform.system()
'Windows'
>>> platform.release()
'XP'
>>> platform.version()
'5.1.2600'

Here's a few different possible calls you can make to identify where you are

import platform
import sys

def linux_distribution():
  try:
    return platform.linux_distribution()
  except:
    return "N/A"

print("""Python version: %s
dist: %s
linux_distribution: %s
system: %s
machine: %s
platform: %s
uname: %s
version: %s
mac_ver: %s
""" % (
sys.version.split('\n'),
str(platform.dist()),
linux_distribution(),
platform.system(),
platform.machine(),
platform.platform(),
platform.uname(),
platform.version(),
platform.mac_ver(),
))

The outputs of this script ran on a few different systems (Linux, Windows, Solaris, MacOS) and architectures (x86, x64, Itanium, power pc, sparc) is available here: https://github.com/hpcugent/easybuild/wiki/OS_flavor_name_version

e.g. Solaris on sparc gave:

Python version: ['2.6.4 (r264:75706, Aug  4 2010, 16:53:32) [C]']
dist: ('', '', '')
linux_distribution: ('', '', '')
system: SunOS
machine: sun4u
platform: SunOS-5.9-sun4u-sparc-32bit-ELF
uname: ('SunOS', 'xxx', '5.9', 'Generic_122300-60', 'sun4u', 'sparc')
version: Generic_122300-60
mac_ver: ('', ('', '', ''), '')

If you're getting this, you may have forgotten to put #include <thread> at the beginning of your file. OP's signature seems like it should work.

If you have zsh installed add alias to .zshrc file in home directory as well.

Modify the show search method like this

showSearch(){
  this.show = !this.show;  
  setTimeout(()=>{ // this will make the execution after the above boolean has changed
    this.searchElement.nativeElement.focus();
  },0);  
}

$(document).ready(function() {
$("#aDateFrom").datepicker({
    onSelect: function() {
        //- get date from another datepicker without language dependencies
        var minDate = $('#aDateFrom').datepicker('getDate');
        $("#aDateTo").datepicker("change", { minDate: minDate });
    }
});

$("#aDateTo").datepicker({
    onSelect: function() {
        //- get date from another datepicker without language dependencies
        var maxDate = $('#aDateTo').datepicker('getDate');
        $("#aDateFrom").datepicker("change", { maxDate: maxDate });
    }
});
});

The error message is fairly self-explanatory

(a,b,c,d,e) = line.split()

expects line.split() to yield 5 elements, but in your case, it is only yielding 1 element. This could be because the data is not in the format you expect, a rogue malformed line, or maybe an empty line - there's no way to know.

To see what line is causing the issue, you could add some debug statements like this:

if len(line.split()) != 11:
    print line

As Martin suggests, you might also be splitting on the wrong delimiter.

from s in context.shift
where !context.employeeshift.Any(es=>(es.shiftid==s.shiftid)&&(es.empid==57))
select s;

Hope this helps

Old post, but I ran into this so if you're trying to output something to Output in a WPF project in Visual Studio, the contemporary method is:

Include this:

using System.Diagnostics;

And then:

Debug.WriteLine("something");

For what purpose?

• Quickest for an IF would be IF EXISTS (SELECT * FROM Table)...
• For a result set, SELECT TOP 1 1 FROM Table returns either zero or one rows
• For exactly one row with a count (0 or non-zero), SELECT COUNT(*) FROM Table

If running Windows 10:

1. Open the start menu
2. Type path
3. Click Edit the system environment variables (usually, it's the top search result) and continue on step 6 below.

If on older Windows:

1. Show Desktop.

2. Right Click My Computer shortcut in the desktop.

3. Click Properties.

4. You should see a section of control Panel - Control Panel\System and Security\System.

5. Click Advanced System Settings on the Left menu.

6. Click Enviornment Variables towards the bottom of the System Properties window.

7. Select PATH in the user variables list.

8. Append your PHP Path (C:\myfolder\php) to your PATH variable, separated from the already existing string by a semi colon.

9. Click OK

10. Open your "cmd"

11. Type PATH, press enter

12. Make sure that you see your PHP folder among the list.

That should work.

Note: Make sure that your PHP folder has the php.exe. It should have the file type CLI. If you do not have the php.exe, go ahead and check the installation guidelines at - http://www.php.net/manual/en/install.windows.manual.php - and download the installation file from there.

You're setting it to not be able to scale (maximum-scale = initial-scale), so it can't scale up when you rotate to landscape mode. Set maximum-scale=1.6 and it will scale properly to fit landscape mode.

../images/logo.png will move you back one folder.

../../images/logo.png will move you back two folders.

/images/logo.png will take you back to the root folder no matter where you are/.

If you use as following, your code can be more effective than you wrote. You should add another feature.

.abc, .xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a.abc, a.xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a {
margin-left:20px;
width: 100px;
height: 100px;
} 

If you're using jQuery UI dialog, you could just style the modal to appear with the position fixed in the window so it doesn't pop-up out of view, negating the need to scroll. Otherwise,

var scrollTop = function() {
    window.scrollTo(0, 0);
};

should do the trick.

Composition

final class Car {

  private final Engine engine;

  Car(EngineSpecs specs) {
    engine = new Engine(specs);
  }

  void move() {
    engine.work();
  }
}

Aggregation

final class Car {

  private Engine engine;

  void setEngine(Engine engine) {
    this.engine = engine;
  }

  void move() {
    if (engine != null)
      engine.work();
  }
}

In the case of composition, the Engine is completely encapsulated by the Car. There is no way for the outside world to get a reference to the Engine. The Engine lives and dies with the car. With aggregation, the Car also performs its functions through an Engine, but the Engine is not always an internal part of the Car. Engines may be swapped, or even completely removed. Not only that, but the outside world can still have a reference to the Engine, and tinker with it regardless of whether it's in the Car.

This is now possible with PHP 5.6.x, using the ... operator (also known as splat operator in some languages):

Example:

function addDateIntervalsToDateTime( DateTime $dt, DateInterval ...$intervals )
{
    foreach ( $intervals as $interval ) {
        $dt->add( $interval );
    }
    return $dt;
}

addDateIntervaslToDateTime( new DateTime, new DateInterval( 'P1D' ), 
        new DateInterval( 'P4D' ), new DateInterval( 'P10D' ) );

Google Drive folders can be embedded and displayed in list and grid views:

List view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#list" style="width:100%; height:600px; border:0;"></iframe>

Grid view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Q: What is a folder ID (FOLDER-ID) and how can I get it?

A: Go to Google Drive >> open the folder >> look at its URL in the address bar of your browser. For example:

Folder URL: https://drive.google.com/drive/folders/0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2

Folder ID:
0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2

Caveat with folders requiring permission

This technique works best for folders with public access. Folders that are shared only with certain Google accounts will cause trouble when you embed them this way. At the time of this edit, a message "You need permission" appears, with some buttons to help you "Request access" or "Switch accounts" (or possibly sign-in to a Google account). The Javascript in these buttons doesn't work properly inside an IFRAME in Chrome.

In the case where you have multiple variables containing the arguments for a command you're running, and not just a single string, you should not use eval directly, as it will fail in the following case:

function echo_arguments() {
  echo "Argument 1: $1"
  echo "Argument 2: $2"
  echo "Argument 3: $3"
  echo "Argument 4: $4"
}

# Note we are passing 3 arguments to `echo_arguments`, not 4
eval echo_arguments arg1 arg2 "Some arg"

Result:

Argument 1: arg1
Argument 2: arg2
Argument 3: Some
Argument 4: arg

Note that even though "Some arg" was passed as a single argument, eval read it as two.

Instead, you can just use the string as the command itself:

# The regular bash eval works by jamming all its arguments into a string then
# evaluating the string. This function treats its arguments as individual
# arguments to be passed to the command being run.
function eval_command() {
  "$@";
}

Note the difference between the output of eval and the new eval_command function:

eval_command echo_arguments arg1 arg2 "Some arg"

Result:

Argument 1: arg1
Argument 2: arg2
Argument 3: Some arg
Argument 4:

Use stringr::str_split_fixed

library(stringr)
str_split_fixed(before$type, "_and_", 2)

To "update" the Toast message after unchecking some items, just put this line inside the for loop:

if (sp.valueAt(i))

so it results:

for(int i=0;i<sp.size();i++)
{
    if (sp.valueAt(i))
        str+=names[sp.keyAt(i)]+",";
}

If your query consists only of the $where operator, you can pass in just the JavaScript expression:

db.T.find("this.Grade1 > this.Grade2");

For greater performance, run an aggregate operation that has a $redact pipeline to filter the documents which satisfy the given condition.

The $redact pipeline incorporates the functionality of $project and $match to implement field level redaction where it will return all documents matching the condition using $$KEEP and removes from the pipeline results those that don't match using the $$PRUNE variable.

Running the following aggregate operation filter the documents more efficiently than using $where for large collections as this uses a single pipeline and native MongoDB operators, rather than JavaScript evaluations with $where, which can slow down the query:

db.T.aggregate([
    {
        "$redact": {
            "$cond": [
                { "$gt": [ "$Grade1", "$Grade2" ] },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    }
])

which is a more simplified version of incorporating the two pipelines $project and $match:

db.T.aggregate([
    {
        "$project": {
            "isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] },
            "Grade1": 1,
            "Grade2": 1,
            "OtherFields": 1,
            ...
        }
    },
    { "$match": { "isGrade1Greater": 1 } }
])

With MongoDB 3.4 and newer:

db.T.aggregate([
    {
        "$addFields": {
            "isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] }
        }
    },
    { "$match": { "isGrade1Greater": 1 } }
])

In my case, for a stateless component that received the ref with forwardRef, I had to do what it is said here https://itnext.io/reusing-the-ref-from-forwardref-with-react-hooks-4ce9df693dd

From this (onClick doesn't have access to the equivalent of 'this')

const Com = forwardRef((props, ref) => {
  return <input ref={ref} onClick={() => {console.log(ref.current} } />
})

To this (it works)

const useCombinedRefs = (...refs) => {
  const targetRef = React.useRef()

  useEffect(() => {
    refs.forEach(ref => {
      if (!ref) return

      if (typeof ref === 'function') ref(targetRef.current)
      else ref.current = targetRef.current
    })
  }, [refs])

  return targetRef
}

const Com = forwardRef((props, ref) => {
  const innerRef = useRef()
  const combinedRef = useCombinedRefs(ref, innerRef)

  return <input ref={combinedRef } onClick={() => {console.log(combinedRef .current} } />
})

So the issue is that UTF-8 code unit values have been stored as a sequence of 16-bit code units in a C# string. You simply need to verify that each code unit is within the range of a byte, copy those values into bytes, and then convert the new UTF-8 byte sequence into UTF-16.

public static string DecodeFromUtf8(this string utf8String)
{
    // copy the string as UTF-8 bytes.
    byte[] utf8Bytes = new byte[utf8String.Length];
    for (int i=0;i<utf8String.Length;++i) {
        //Debug.Assert( 0 <= utf8String[i] && utf8String[i] <= 255, "the char must be in byte's range");
        utf8Bytes[i] = (byte)utf8String[i];
    }

    return Encoding.UTF8.GetString(utf8Bytes,0,utf8Bytes.Length);
}

DecodeFromUtf8("d\u00C3\u00A9j\u00C3\u00A0"); // déjà

This is easy, however it would be best to find the root cause; the location where someone is copying UTF-8 code units into 16 bit code units. The likely culprit is somebody converting bytes into a C# string using the wrong encoding. E.g. Encoding.Default.GetString(utf8Bytes, 0, utf8Bytes.Length).

Alternatively, if you're sure you know the incorrect encoding which was used to produce the string, and that incorrect encoding transformation was lossless (usually the case if the incorrect encoding is a single byte encoding), then you can simply do the inverse encoding step to get the original UTF-8 data, and then you can do the correct conversion from UTF-8 bytes:

public static string UndoEncodingMistake(string mangledString, Encoding mistake, Encoding correction)
{
    // the inverse of `mistake.GetString(originalBytes);`
    byte[] originalBytes = mistake.GetBytes(mangledString);
    return correction.GetString(originalBytes);
}

UndoEncodingMistake("d\u00C3\u00A9j\u00C3\u00A0", Encoding(1252), Encoding.UTF8);

This is what worked for me on iOS 6 (very slight adaptation of rmarscher's answer):

<script>                                                                
    (function(document,navigator,standalone) {                          
        if (standalone in navigator && navigator[standalone]) {         
            var curnode,location=document.location,stop=/^(a|html)$/i;  
            document.addEventListener("click", function(e) {            
                curnode=e.target;                                       
                while (!stop.test(curnode.nodeName)) {                  
                    curnode=curnode.parentNode;

            },false);

A somewhat different approach using ggplot2:

dat <- read.table(text = "A   B   C   D   E   F    G
1 480 780 431 295 670 360  190
2 720 350 377 255 340 615  345
3 460 480 179 560  60 735 1260
4 220 240 876 789 820 100   75", header = TRUE)

library(reshape2)

dat$row <- seq_len(nrow(dat))
dat2 <- melt(dat, id.vars = "row")

library(ggplot2)

ggplot(dat2, aes(x = variable, y = value, fill = row)) + 
  geom_bar(stat = "identity") +
  xlab("\nType") +
  ylab("Time\n") +
  guides(fill = FALSE) +
  theme_bw()

this gives:

When you want to include a legend, delete the guides(fill = FALSE) line.

Thought I'd consolidate the answers and show some timeit results.

Python 2 sucks pretty bad at this, but map is a bit faster than comprehension.

Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:42:59) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import timeit
>>> setup = """import random
random.seed(10)
l = [str(random.randint(0, 99)) for i in range(100)]"""
>>> timeit.timeit('[int(v) for v in l]', setup)
116.25092001434314
>>> timeit.timeit('map(int, l)', setup)
106.66044823117454

Python 3 is over 4x faster by itself, but converting the map generator object to a list is still faster than comprehension, and creating the list by unpacking the map generator (thanks Artem!) is slightly faster still.

Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) [MSC v.1900 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

l = [str(random.randint(0, 99)) for i in range(100)]"""

25.133059591551955
>>> timeit.timeit('list(map(int, l))', setup)
19.705547827217515
>>> timeit.timeit('[*map(int, l)]', setup)
19.45838406513076

Note: In Python 3, 4 elements seems to be the crossover point (3 in Python 2) where comprehension is slightly faster, though unpacking the generator is still faster than either for lists with more than 1 element.

Try this:

/\d{3}-(?:(apple|banana)-)?\d{3}/

New answer, powershell

TCP

Get-Process -Id (Get-NetTCPConnection -LocalPort YourPortNumberHere).OwningProcess

UDP

Get-Process -Id (Get-NetUDPEndpoint -LocalPort YourPortNumberHere).OwningProcess

Old answer, cmd

 C:\> netstat -a -b

(Add -n to stop it trying to resolve hostnames, which will make it a lot faster.)

Note Dane's recommendation for TCPView. It looks very useful!

-a Displays all connections and listening ports.

-b Displays the executable involved in creating each connection or listening port. In some cases well-known executables host multiple independent components, and in these cases the sequence of components involved in creating the connection or listening port is displayed. In this case the executable name is in [] at the bottom, on top is the component it called, and so forth until TCP/IP was reached. Note that this option can be time-consuming and will fail unless you have sufficient permissions.

-n Displays addresses and port numbers in numerical form.

-o Displays the owning process ID associated with each connection.

Put in config.php this

Basically we had to enable TLS 1.2 for .NET 4.x. Making this registry changed worked for me, and stopped the event log filling up with the Schannel error.

More information on the answer can be found here

Linked Info Summary

Enable TLS 1.2 at the system (SCHANNEL) level:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

(equivalent keys are probably also available for other TLS versions)

Tell .NET Framework to use the system TLS versions:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001

This may not be desirable for edge cases where .NET Framework 4.x applications need to have different protocols enabled and disabled than the OS does.

Forget trying to decipher the example .ts - as others have said it is often incomplete.

Instead just click on the 'pop-out' icon circled here and you'll get a fully working StackBlitz example.

You can quickly confirm the required modules:

Comment out any instances of ReactiveFormsModule, and sure enough you'll get the error:

Template parse errors:
Can't bind to 'formControl' since it isn't a known property of 'input'. 

You can try below xPath pattern,

  XPathExpression expr = xPath.compile("/bookstore/book/title[@lang='eng']")

You're probably setting a value for a key in the alertView, which is not allowed. The key is in this case LoginScreen. I don't see any call to setValue(), so I assume it's somewhere else in the code.

Use Console.Write instead, so there's no newline written:

Console.Write("What is your name? ");
var name = Console.ReadLine();

You config proxy settings for some network and now you connect another network. Now have to remove the proxy settings. For that use these commands:

git config --global --unset https.proxy
git config --global --unset http.proxy

Now you can push too. (If did not remove proxy configuration still you can use git commands like add , commit and etc)

rename fgh jkl fgh*

You have to use at least version 3.2.8.RELEASE of spring-core.

For Maven, set in your pom.xml:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>3.2.8.RELEASE</version>
</dependency>

Source: http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/cglib/core/SpringNamingPolicy.html, since 3.2.8.

For people with a similar question and find this post (like I did); you can do this even without lastrow if your dataset is formatted as a table.

Range("tablename[columnname]").Formula = "=G3&"",""&L3"

Making it a true one liner. Hope it helps someone!

The example creates a list of named lists in a loop.

  MyList <- list()
  for (aName in c("name1", "name2")){
    MyList[[aName]] <- list(aName)
  }
  MyList[["name1"]]
  MyList[["name2"]]

To add another list named "name3" do write:

  MyList$name3 <- list(1, 2, 3)

I created an extension for RelativeLayout that shows/hides Layouts with animations. It can extend any kind of View to gain these features.

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationSet;
import android.view.animation.AnimationUtils;
import android.widget.RelativeLayout;

public class AnimatingRelativeLayout extends RelativeLayout
{
    Context context;
    Animation inAnimation;
    Animation outAnimation;

    public AnimatingRelativeLayout(Context context)
    {
        super(context);
        this.context = context;
        initAnimations();

    }

    public AnimatingRelativeLayout(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        this.context = context;
        initAnimations();
    }

    public AnimatingRelativeLayout(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
        this.context = context;
        initAnimations();
    }

    private void initAnimations()
    {
        inAnimation = (AnimationSet) AnimationUtils.loadAnimation(context, R.anim.in_animation);
        outAnimation = (Animation) AnimationUtils.loadAnimation(context, R.anim.out_animation);
    }

    public void show()
    {
        if (isVisible()) return;
        show(true);
    }

    public void show(boolean withAnimation)
    {
        if (withAnimation) this.startAnimation(inAnimation);
        this.setVisibility(View.VISIBLE);
    }

    public void hide()
    {
        if (!isVisible()) return;
        hide(true);
    }

    public void hide(boolean withAnimation)
    {
        if (withAnimation) this.startAnimation(outAnimation);
        this.setVisibility(View.GONE);
    }

    public boolean isVisible()
    {
        return (this.getVisibility() == View.VISIBLE);
    }

    public void overrideDefaultInAnimation(Animation inAnimation)
    {
        this.inAnimation = inAnimation;
    }

    public void overrideDefaultOutAnimation(Animation outAnimation)
    {
        this.outAnimation = outAnimation;
    }
}

You can override the original Animations using overrideDefaultInAnimation and overrideDefaultOutAnimation

My original Animations were fadeIn/Out, I am adding XML animation files for Translating in/out of the screen (Translate to top and from top)

in_animation.xml:

    <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="600"
    android:fillAfter="false"
    android:fromXDelta="0"
    android:fromYDelta="-100%p"
    android:toXDelta="0"
    android:toYDelta="0" />

out_animation.xml:

  <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="600"
    android:fillAfter="false"
    android:fromXDelta="0"
    android:fromYDelta="0"
    android:toXDelta="0"
    android:toYDelta="-100%p" />

I don't know if this is even usefull or not but I was strugling with the same problem and I found a pretty easy way, with only a global boolean variable and onResume() action. In my case, my Activity C if clicked in a specific button it should trigger the finish() of Activity B!

Activity_A -> Activity_B -> Activity_C

Activity_A (opens normally Activity_B)

Activity_B (on some button click opens Activity_C):

// Global:
boolean its_detail = false;
// -------
SharedPreferences prefs =  getApplicationContext().getSharedPreferences("sharedpreferences", 0);
boolean v = prefs.getBoolean("select_client", false);

its_detail = v;

startActivity(C);

@Override
public void onResume(){
     super.onResume();
     if(its_detail == true){
        finish();
     }
}

So, whenever I click the button on Activity C it would do the "onResume()" function of Activity B and go back to Activity A.

In imports

import re

In run time processing:

RE_TEST = r'test'
if re.match(RE_TEST, 'TeSt', re.IGNORECASE):

It should be mentioned that not using re.compile is wasteful. Every time the above match method is called, the regular expression will be compiled. This is also faulty practice in other programming languages. The below is the better practice.

In app initialization:

self.RE_TEST = re.compile('test', re.IGNORECASE)

In run time processing:

if self.RE_TEST.match('TeSt'):

In JDK 1.7, you can get system CPU and memory usage via com.sun.management.OperatingSystemMXBean. This is different than java.lang.management.OperatingSystemMXBean.

long    getCommittedVirtualMemorySize()
Returns the amount of virtual memory that is guaranteed to be available to the running process in bytes, or -1 if this operation is not supported.

long    getFreePhysicalMemorySize()
Returns the amount of free physical memory in bytes.

long    getFreeSwapSpaceSize()
Returns the amount of free swap space in bytes.

You have a lot of unnecessary keyframes. Don't think of keyframes as individual frames, think of them as "steps" in your animation and the computer fills in the frames between the keyframes.

Here is a solution that cleans up a lot of code and makes the animation start from the center:

.gps_ring {
    border: 3px solid #999;
    -webkit-border-radius: 30px;
    height: 18px;
    width: 18px;
    position: absolute;
    left:20px;
    top:214px;
    -webkit-animation: pulsate 1s ease-out;
    -webkit-animation-iteration-count: infinite; 
    opacity: 0.0
}
@-webkit-keyframes pulsate {
    0% {-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
    50% {opacity: 1.0;}
    100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}

I'm on Windows 7 64 bit and couldn't understand if I can manually enable JRE8 64 bit for Chrome. Turned out that my problem was that Java plugin DLL is 64 bit which wouldn't work in 32 bit Chrome. Therefore you need to install x86 version of JRE. Below are Windows registry settings you need to create

we can find length of array by using array_name.length attribute

int [] i = i.length;

If you mean lists, try ==:

l1 = [1,2,3]
l2 = [1,2,3,4]

l1 == l2 # False

If you mean array:

l1 = array('l', [1, 2, 3])
l2 = array('d', [1.0, 2.0, 3.0])
l1 == l2 # True
l2 = array('d', [1.0, 2.0, 3.0, 4.0])
l1 == l2 # False

If you want to compare strings (per your comment):

date_string  = u'Thu Sep 16 13:14:15 CDT 2010'
date_string2 = u'Thu Sep 16 14:14:15 CDT 2010'
date_string == date_string2 # False

For external link simply use an achor in place of Link:

<a rel="noopener noreferrer" href="http://url.com" target="_blank">Link Here</a>

With reversed and list:

>>> list1 = [1,2,3]
>>> reversed_list = list(reversed(list1))
>>> reversed_list
>>> [3, 2, 1]

If you can get i["MyPhone"] as a long, you can use the long.ToString() method to format it:

Convert.ToLong(i["MyPhone"]).ToString("###-###-####");

See the MSDN page on Numeric Format Strings.

Be careful to use long rather than int: int could overflow.

If you're passing literals in code, what's stopping you from simply declaring it ahead of time?

byte b = 0; //Set to desired value.
f(b);

Weird, just had simmilar issue, went here http://www.microsoft.com/en-us/download/confirmation.aspx?id=30679 downloaded and installed vcredist_x86 (i'm using 32bit apache) and it works like a charm.

You can do it like this

$(function(){_x000D_
  $("tr").find("td:eq(0)").css("color","red");_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<table>_x000D_
  <tr>_x000D_
    <td>col_1</td>_x000D_
    <td>col_2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>col_1</td>_x000D_
    <td>col_2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>col_1</td>_x000D_
    <td>col_2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>col_1</td>_x000D_
    <td>col_2</td>_x000D_
  </tr>_x000D_

The lingo in excel is different, you don't "declare variables", you "name" cells or arrays.

A good overview of how you do that is below: http://office.microsoft.com/en-001/excel-help/define-and-use-names-in-formulas-HA010342417.aspx

I think that you could use a POST or PATCH method to handle this since they typically design for this.

• Using a POST method is typically used to add an element when used on list resource but you can also support several actions for this method. See this answer: How to Update a REST Resource Collection. You can also support different representation formats for the input (if they correspond to an array or a single elements).

  In the case, it's not necessary to define your format to describe the update.

• Using a PATCH method is also suitable since corresponding requests correspond to a partial update. According to RFC5789 (http://tools.ietf.org/html/rfc5789):

  Several applications extending the Hypertext Transfer Protocol (HTTP) require a feature to do partial resource modification. The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.

  In the case, you have to define your format to describe the partial update.

I think that in this case, POST and PATCH are quite similar since you don't really need to describe the operation to do for each element. I would say that it depends on the format of the representation to send.

The case of PUT is a bit less clear. In fact, when using a method PUT, you should provide the whole list. As a matter of fact, the provided representation in the request will be in replacement of the list resource one.

You can have two options regarding the resource paths.

• Using the resource path for doc list

In this case, you need to explicitely provide the link of docs with a binder in the representation you provide in the request.

Here is a sample route for this /docs.

The content of such approach could be for method POST:

[
    { "doc_number": 1, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 2, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 3, "binder": 5, (other fields in the case of creation) },
    (...)
]

• Using sub resource path of binder element

In addition you could also consider to leverage sub routes to describe the link between docs and binders. The hints regarding the association between a doc and a binder doesn't have now to be specified within the request content.

Here is a sample route for this /binder/{binderId}/docs. In this case, sending a list of docs with a method POST or PATCH will attach docs to the binder with identifier binderId after having created the doc if it doesn't exist.

The content of such approach could be for method POST:

[
    { "doc_number": 1, (other fields in the case of creation) },
    { "doc_number": 2, (other fields in the case of creation) },
    { "doc_number": 3, (other fields in the case of creation) },
    (...)
]

Regarding the response, it's up to you to define the level of response and the errors to return. I see two levels: the status level (global level) and the payload level (thinner level). It's also up to you to define if all the inserts / updates corresponding to your request must be atomic or not.

• Atomic

In this case, you can leverage the HTTP status. If everything goes well, you get a status 200. If not, another status like 400 if the provided data aren't correct (for example binder id not valid) or something else.

• Non atomic

In this case, a status 200 will be returned and it's up to the response representation to describe what was done and where errors eventually occur. ElasticSearch has an endpoint in its REST API for bulk update. This could give you some ideas at this level: http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/bulk.html.

• Asynchronous

You can also implement an asynchronous processing to handle the provided data. In this case, the HTTP status returns will be 202. The client needs to pull an additional resource to see what happens.

Before finishing, I also would want to notice that the OData specification addresses the issue regarding relations between entities with the feature named navigation links. Perhaps could you have a look at this ;-)

If you want to remove only line terminators that are valid on the current OS, you could do this:

text = text.replaceAll(System.getProperty("line.separator"), "");

If you want to make sure you remove any line separators, you can do it like this:

text = text.replaceAll("\\r|\\n", "");

Or, slightly more verbose, but less regexy:

text = text.replaceAll("\\r", "").replaceAll("\\n", "");

You can use ngx-format-field. It is a directive to format the input value which will appear in the view. It will not manipulate the Input value which will be saved in the backend. See link here!

Example:

component.html:

<input type="text" formControlName="currency" [appFormatFields]="CURRENCY"
(change)="onChangeCurrency()">

component.ts

onChangeCurrency() {
this.currency.patchValue(this.currency.value);
}

Just wanted to add to an old thread to hopefully aid other people. I needed programmatically add a cert to the firefox database using a GPO, this was how I did it for Windows

1, First download and unzip the precompiled firefox NSS nss-3.13.5-nspr-4.9.1-compiled-x86.zip

2, Add the cert manually to firefox Options-->Advanced--Certificates-->Authorities-->Import

3, from the downloaded NSS package, run

certutil -L -d c:\users\[username]\appdata\roaming\mozilla\firefox\[profile].default    

4, The above query will show you the certificate name and Trust Attributes e.g.

my company Ltd                                CT,C,C    

5, Delete the certificate in step 2. Options-->Advanced--Certificates-->Authorities-->Delete

6, Create a powershell script using the information from step 4 as follows. This script will get the users profile path and add the certificate. This only works if the user has one firefox profile (need somehow to retrieve the users firefox folder profile name)

#Script adds Radius Certificate to independent Firefox certificate store since the browser does not use the Windows built in certificate store    


#Get Firefox profile cert8.db file from users windows profile path
$ProfilePath = "C:\Users\" + $env:username + "\AppData\Roaming\Mozilla\Firefox\Profiles\"
$ProfilePath = $ProfilePath + (Get-ChildItem $ProfilePath | ForEach-Object { $_.Name }).ToString()

#Update firefox cert8.db file with Radius Certificate
certutil -A -n "UK my company" -t "CT,C,C" -i CertNameToAdd.crt -d $ProfilePath    

7, Create GPO as a User Configuration to run the PowerShell script

Hope that helps save someone time

I know this is an older question, but I wanted to post an answer for users with the same question:

curl -H 'Cache-Control: no-cache' http://www.example.com

This curl command servers in its header request to return non-cached data from the web server.
