Save the count as you go - and use validation to enforce it. I hacked this together - for keeping a count of unique votes and counts which keeps coming up!. But this time I have tested my suggestion! (notwithstanding cut/paste errors!).

The 'trick' here is to use the node priority to as the vote count...

The data is:

vote/$issueBeingVotedOn/user/$uniqueIdOfVoter = thisVotesCount, priority=thisVotesCount vote/$issueBeingVotedOn/count = 'user/'+$idOfLastVoter, priority=CountofLastVote

,"vote": {
  ".read" : true
  ,".write" : true
  ,"$issue" : {
    "user" : {
      "$user" : {
        ".validate" : "!data.exists() && 
             newData.val()==data.parent().parent().child('count').getPriority()+1 &&
             newData.val()==newData.GetPriority()" 

user can only vote once && count must be one higher than current count && data value must be same as priority.

      }
    }
    ,"count" : {
      ".validate" : "data.parent().child(newData.val()).val()==newData.getPriority() &&
             newData.getPriority()==data.getPriority()+1 "
    }

count (last voter really) - vote must exist and its count equal newcount, && newcount (priority) can only go up by one.

  }
}

Test script to add 10 votes by different users (for this example, id's faked, should user auth.uid in production). Count down by (i--) 10 to see validation fail.

<script src='https://cdn.firebase.com/v0/firebase.js'></script>
<script>
  window.fb = new Firebase('https:...vote/iss1/');
  window.fb.child('count').once('value', function (dss) {
    votes = dss.getPriority();
    for (var i=1;i<10;i++) vote(dss,i+votes);
  } );

function vote(dss,count)
{
  var user='user/zz' + count; // replace with auth.id or whatever
  window.fb.child(user).setWithPriority(count,count);
  window.fb.child('count').setWithPriority(user,count);
}
</script>

The 'risk' here is that a vote is cast, but the count not updated (haking or script failure). This is why the votes have a unique 'priority' - the script should really start by ensuring that there is no vote with priority higher than the current count, if there is it should complete that transaction before doing its own - get your clients to clean up for you :)

The count needs to be initialised with a priority before you start - forge doesn't let you do this, so a stub script is needed (before the validation is active!).

In simple, Normalisation is Reduction of Redundancies.
Examples of Redundancies:
a) white spaces outside of the root/document tags(...<document></document>...)
b) white spaces within start tag (<...>) and end tag (</...>)
c) white spaces between attributes and their values (ie. spaces between key name and =")
d) superfluous namespace declarations
e) line breaks/white spaces in texts of attributes and tags
f) comments etc...

Balanced tree is a tree whose height is of order of log(number of elements in the tree).

height = O(log(n))
O, as in asymptotic notation i.e. height should have same or lower asymptotic
growth rate than log(n)
n: number of elements in the tree

The definition given "a tree is balanced of each sub-tree is balanced and the height of the two sub-trees differ by at most one" is followed by AVL trees.

Since, AVL trees are balanced but not all balanced trees are AVL trees, balanced trees don't hold this definition and internal nodes can be unbalanced in them. However, AVL trees require all internal nodes to be balanced.

Since the question asks for an available data structure, a tree can be constructed from lists or arrays:

Object[] tree = new Object[2];
tree[0] = "Hello";
{
  Object[] subtree = new Object[2];
  subtree[0] = "Goodbye";
  subtree[1] = "";
  tree[1] = subtree;
}

instanceof can be used to determine whether an element is a subtree or a terminal node.

I guess one crucial point you people are missing is difference between data and pointers as explained in this section.

Pointer : pointer to other nodes.

Data :- In context of database indexes, data is just another pointer to real data (row) which reside somewhere else.

Hence in case of B tree each node has three information keys, pointers to data associated with the keys and pointer to child nodes.

In B+ tree internal node keep keys and pointers to child node while leaf node keep keys and pointers to associated data. This allows more number of key for a given size of node. Size of node is determined mainly by block size.

Advantage of having more key per node is explained well above so I will save my typing effort.

You do not need to calculate tree depths on the fly.

You can maintain them as you perform operations.

Furthermore, you don't actually in fact have to maintain track of depths; you can simply keep track of the difference between the left and right tree depths.

http://www.eternallyconfuzzled.com/tuts/datastructures/jsw_tut_avl.aspx

Just keeping track of the balance factor (difference between left and right subtrees) is I found easier from a programming POV, except that sorting out the balance factor after a rotation is a PITA...

your thinking about this program below

#include <stdio.h>
#include <string.h>

int main ()
{
char str[][5] = { "R2D2" , "C3PO" , "R2A6" };
int n;
puts ("Looking for R2 astromech droids...");
for (n=0 ; n<3 ; n++)
if (strncmp (str[n],"R2xx",2) == 0)
{
  printf ("found %s\n",str[n]);
}
return 0;
}
//outputs:
//
//Looking for R2 astromech droids...
//found R2D2
//found R2A6

when you should be thinking about inputting something into an array & then use strcmp functions like the program above ... check out a modified program below

#include <iostream>
#include<cctype>
#include <string.h>
#include <string>
using namespace std;

int main()
{
int Students=2;
int Projects=3, Avg2=0, Sum2=0, SumT2=0, AvgT2=0, i=0, j=0;
int Grades[Students][Projects];

for(int j=0; j<=Projects-1; j++){
  for(int i=0; i<=Students; i++) {
 cout <<"Please give grade of student "<< j <<"in project "<< i  <<  ":";
  cin >> Grades[j][i];

  }
  Sum2 = Sum2 + Grades[i][j];
     Avg2 = Sum2/Students;
}
SumT2 = SumT2 + Avg2;
AvgT2 = SumT2/Projects;
cout << "avg is  : " << AvgT2 << " and sum : " << SumT2 << ":";
return 0;
}

change to string except it only reads 1 input and throws the rest out maybe need two for loops and two pointers

#include <cstring>
#include <iostream>
#include <string>
#include <stdio.h>
using namespace std;
int main()
{
char name[100];
//string userInput[26];
int i=0, n=0, m=0;
cout<<"your name? ";
cin>>name;
cout<<"Hello "<<name<< endl;

char *ptr=name;
for (i = 0; i < 20; i++)
{
cout<<i<<" "<<ptr[i]<<" "<<(int)ptr[i]<<endl;
}   
int length = 0;
while(name[length] != '\0')
{
length++;
}
                    for(n=0; n<4; n++)
                {
                            if (strncmp(ptr, "snit", 4) == 0)
                            {
            cout << "you found the snitch "    <<        ptr[i];
                            }
                }
cout<<name <<"is"<<length<<"chars long";
}

You probably want ANSI color codes. Most *nix terminals support them.

I tried a lot of ways and functions that suggested above, but they didn't work in my project. Anyway I have found solution and here it is:

try {
    InputStream path = this.getClass().getClassLoader().getResourceAsStream("img/left-hand.png");
    img = ImageIO.read(path);
} catch (IOException e) {
    e.printStackTrace();
}

In addition to the other answers, the fmod documentation has some interesting things to say on the subject:

math.fmod(x, y)

Return fmod(x, y), as defined by the platform C library. Note that the Python expression x % y may not return the same result. The intent of the C standard is that fmod(x, y) be exactly (mathematically; to infinite precision) equal to x - n*y for some integer n such that the result has the same sign as x and magnitude less than abs(y). Python’s x % y returns a result with the sign of y instead, and may not be exactly computable for float arguments. For example, fmod(-1e-100, 1e100) is -1e-100, but the result of Python’s -1e-100 % 1e100 is 1e100-1e-100, which cannot be represented exactly as a float, and rounds to the surprising 1e100. For this reason, function fmod() is generally preferred when working with floats, while Python’s x % y is preferred when working with integers.

Ensure that you are loading jQuery before you use Bootstrap. Sounds basic, but I was having issues catching these modal events and turns out the error was not with my code but that I was loading Bootstrap before jQuery.

Normally virtualenv creates environments in the current directory. Unless you're intending to create virtual environments in C:\Windows\system32 for some reason, I would use a different directory for environments.

You shouldn't need to mess with paths: use the activate script (in <env>\Scripts) to ensure that the Python executable and path are environment-specific. Once you've done this, the command prompt changes to indicate the environment. You can then just invoke easy_install and whatever you install this way will be installed into this environment. Use deactivate to set everything back to how it was before activation.

Example:

c:\Temp>virtualenv myenv
New python executable in myenv\Scripts\python.exe
Installing setuptools..................done.
c:\Temp>myenv\Scripts\activate
(myenv) C:\Temp>deactivate
C:\Temp>

Notice how I didn't need to specify a path for deactivate - activate does that for you, so that when activated "Python" will run the Python in the virtualenv, not your system Python. (Try it - do an import sys; sys.prefix and it should print the root of your environment.)

You can just activate a new environment to switch between environments/projects, but you'll need to specify the whole path for activate so it knows which environment to activate. You shouldn't ever need to mess with PATH or PYTHONPATH explicitly.

If you use Windows Powershell then you can take advantage of a wrapper. On Linux, the virtualenvwrapper (the link points to a port of this to Powershell) makes life with virtualenv even easier.

Update: Not incorrect, exactly, but perhaps not quite in the spirit of virtualenv. You could take a different tack: for example, if you install Django and anything else you need for your site in your virtualenv, then you could work in your project directory (where you're developing your site) with the virtualenv activated. Because it was activated, your Python would find Django and anything else you'd easy_installed into the virtual environment: and because you're working in your project directory, your project files would be visible to Python, too.

Further update: You should be able to use pip, distribute instead of setuptools, and just plain python setup.py install with virtualenv. Just ensure you've activated an environment before installing something into it.

To date (mysql 8.0.18) there is no suitable function inside mysql to re-create indexes.
Since mysql 8.0 myisam is slowly phasing into deprecated status, innodb is the current main storage engine.
In most practical cases innodb is the best choice and it's supposed to keep indexes working well.
In most practical cases innodb also does a good job, you do not need to recreate indexes. Almost always.

When it comes to large tables with hundreds of GB data amd rows and a lot of writing the situation changes, indexes can degrade in performance.
In my personal case I've seen performance drop from ~15 minutes for a count(*) using a secondary index to 4300 minutes after 2 months of writing to the table with linear time increase.
After recreating the index the performance goes back to 15 minutes.

To date we have two options to do that:
1) OPTIMIZE TABLE (or ALTER TABLE)
Innodb doesn't support optimization so in both cases the entire table will be read and re-created.
This means you need the storage for the temporary file and depending on the table a lot of time (I've cases where an optimize takes a week to complete). This will compact the data and rebuild all indexes.
Despite not being officially recommended, I highly recommend the OPTIMIZE process on write-heavy tables up to 100GB in size.

2) ALTER TABLE DROP KEY -> ALTER TABLE ADD KEY
You manually drop the key by name, you manually create it again. In a production environment you'll want to create it first, then drop the old version.
The upside: this can be a lot faster than optimize. The downside: you need to manually create the syntax.
"SHOW CREATE TABLE" can be used to quickly see which indexes are available and how they are called.

Appendix:
1) To just update statistics you can use the already mentioned "ANALYZE TABLE".
2) If you experience performance degradation on write-heavy servers you might need to restart mysql. There are a couple of bugs in current mysql (8.0) that can cause significant slowdown without showing up in error log. Eventually those slowdowns lead to a server crash but it can take weeks or even months to build up to the crash, in this process the server gets slower and slower in responses.
3) If you wish to re-create a large table that takes weeks to complete or fails after hours due to internal data integrity problems you should do a CREATE TABLE LIKE, INSERT INTO SELECT *. then 'atomic RENAME' the tables.
4) If INSERT INTO SELECT * takes hours to days to complete on huge tables you can speed up the process by about 20-30 times using a multi-threaded approach. You "partition" the table into chunks and INSERT INTO SELECT * in parallel.

Actually there is another (maybe better solution) where you can use the angular's native 'filter' filter and still pass arguments to your custom filter.

Consider the following code:

<div ng-repeat="group in groups">
    <li ng-repeat="friend in friends | filter:weDontLike(group.enemy.name)">
        <span>{{friend.name}}</span>
    <li>
</div>

To make this work you just define your filter as the following:

$scope.weDontLike = function(name) {
    return function(friend) {
        return friend.name != name;
    }
}

As you can see here, weDontLike actually returns another function which has your parameter in its scope as well as the original item coming from the filter.

It took me 2 days to realise you can do this, haven't seen this solution anywhere yet.

Checkout Reverse polarity of an angular.js filter to see how you can use this for other useful operations with filter.

These steps work for me:

• Open the file in Jupyter Notebook.
• Rename the file: Click File > Rename, change the name so that it ends with '.ipynb' behind, and click OK
• Close the file.
• From the Jupyter Notebook's directory tree, click the filename to open it.

You could do that. First make sure Dog really exists in the array, then remove it. Add the for statement if you believe Dog may happens more than once on your array.

var animals = ["Dog", "Cat", "Mouse", "Dog"]
let animalToRemove = "Dog"

for object in animals {
    if object == animalToRemove {
        animals.remove(at: animals.firstIndex(of: animalToRemove)!)
    }
}

If you are sure Dog exits in the array and happened only once just do that:

animals.remove(at: animals.firstIndex(of: animalToRemove)!)

If you have both, strings and numbers

var array = [12, 23, "Dog", 78, 23]
let numberToRemove = 23
let animalToRemove = "Dog"

for object in array {

    if object is Int {
        // this will deal with integer. You can change to Float, Bool, etc...
        if object == numberToRemove {
        array.remove(at: array.firstIndex(of: numberToRemove)!)
        }
    }
    if object is String {
        // this will deal with strings
        if object == animalToRemove {
        array.remove(at: array.firstIndex(of: animalToRemove)!)
        }
    }
}

This might help someone who use Zend_Oauth_Client to work with twitter api. This working config:

$accessToken = new Zend_Oauth_Token_Access();
$accessToken->setToken('accessToken');
$accessToken->setTokenSecret('accessTokenSecret');

$client = $accessToken->getHttpClient(array(
    'requestScheme' => Zend_Oauth::REQUEST_SCHEME_HEADER,
    'version' => '1.0', // it was 1.1 and I got 215 error.
    'signatureMethod' => 'HMAC-SHA1',
    'consumerKey' => 'foo',
    'consumerSecret' => 'bar',
    'requestTokenUrl' => 'https://api.twitter.com/oauth/request_token',
    'authorizeUrl' => 'https://api.twitter.com/oauth/authorize',
    'accessTokenUrl' => 'https://api.twitter.com/oauth/access_token',
    'timeout' => 30
));

It look like twitter api 1.0 allows oauth version to be 1.1 and 1.0, where twitter api 1.1 require only oauth version to be 1.0.

P.S We do not use Zend_Service_Twitter as it does not allow send custom params on status update.

In my case the problem was that a method was defined in some Interface A as default, while its sub-class overrode it as private. Then when the method was called, the java Runtime realized it was calling a private method.

I am still puzzled as to why the compiler didn't complain about the private override..

public interface A {
     default void doStuff() {
         // doing stuff
     }
}

public class B {
     private void doStuff() {
         // do other stuff instead
     }
}

public static final main(String... args) {
    A someB = new B();
    someB.doStuff();
}

If you compile with optimizations enabled, then many variables will be removed; for example:

SomeType value = GetValue();
DoSomething(value);

here the local variable value would typically get removed, keeping the value on the stack instead - a bit like as if you had written:

DoSomething(GetValue());

Also, if a return value isn't used at all, then it will be dropped via "pop" (rather than stored in a local via "stloc", and again; the local will not exist).

Because of this, in such a build the debugger can't get the current value of value because it doesn't exist - it only exists for the brief instant between GetValue() and DoSomething(...).

So; if you want to debug... don't use a release build! or at least, disable optimizations while you debug.

This error can be due to many many things.

The key here seems the hint about error reading. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.

You could also try with sudo, that might solve a permission problem if that's the case.

Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...

I guess no one mentioned this so I will write it here. In phpMyAdmin 4.x, there is "Add Routine" link under "Routines" tab at the top row. This link opens a popup dialog where you can write your Stored procedure without worrying about delimiter or template.

Add Routine

Note that for simple test stored procedure, you may want to drop the default parameter which is already given or you can simply set it with a value.

One useful trick in SQL is the ability use @var = function(...) to assign a value. If you have multiple records in your record set, your var is assigned multiple times with side-effects:

declare @badStrings table (item varchar(50))

INSERT INTO @badStrings(item)
SELECT '>' UNION ALL
SELECT '<' UNION ALL
SELECT '(' UNION ALL
SELECT ')' UNION ALL
SELECT '!' UNION ALL
SELECT '?' UNION ALL
SELECT '@'

declare @testString varchar(100), @newString varchar(100)

set @teststring = 'Juliet ro><0zs my s0x()rz!!?!one!@!@!@!'
set @newString = @testString

SELECT @newString = Replace(@newString, item, '') FROM @badStrings

select @newString -- returns 'Juliet ro0zs my s0xrzone'

I got the following error messages using Visual Studio 2017 CE.

Failed to push to the remote repository. See the Output window for more details.

The output window showed the following:

Error encountered while pushing to the remote repository: Git process failed unexpectedly. PushCommand.ExecutePushCommand

I tried to push changes using GitHub Desktop. It shows the following error message.

Cannot push these commits as they contain an email address marked as private on GitHub.

That's It. Solution:

open GitHub account >> Settings >> Emails >> Uncheck "Keep my email address private"

It's done. That was the problem in my case.

You can use pydoc.

Open your terminal and type python -m pydoc list.append

The advantage of pydoc over help() is that you do not have to import a module to look at its help text. For instance python -m pydoc random.randint.

Also you can start an HTTP server to interactively browse documentation by typing python -m pydoc -b (python 3)

For more information python -m pydoc

Is this what you are looking for:

myListBox.DataSource = MyList;

If your example represents your real code, the problem is not in the push, it's that your constructor doesn't do anything.

You need to declare and initialize the x and y members.

Explicitly:

export class Pixel {
    public x: number;
    public y: number;   
    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

Or implicitly:

export class Pixel {
    constructor(public x: number, public y: number) {}
}

I would like to make the case for SPA being best for Data Driven Applications. gmail, of course is all about data and thus a good candidate for a SPA.

But if your page is mostly for display, for example, a terms of service page, then a SPA is completely overkill.

I think the sweet spot is having a site with a mixture of both SPA and static/MVC style pages, depending on the particular page.

For example, on one site I am building, the user lands on a standard MVC index page. But then when they go to the actual application, then it calls up the SPA. Another advantage to this is that the load-time of the SPA is not on the home page, but on the app page. The load time being on the home page could be a distraction to first time site users.

This scenario is a little bit like using Flash. After a few years of experience, the number of Flash only sites dropped to near zero due to the load factor. But as a page component, it is still in use.

If a method on a module is turned into a module function you can simply call it off of Mods as if it had been declared as

module Mods
  def self.foo
     puts "Mods.foo(self)"
  end
end

The module_function approach below will avoid breaking any classes which include all of Mods.

module Mods
  def foo
    puts "Mods.foo"
  end
end

class Includer
  include Mods
end

Includer.new.foo

Mods.module_eval do
  module_function(:foo)
  public :foo
end

Includer.new.foo # this would break without public :foo above

class Thing
  def bar
    Mods.foo
  end
end

Thing.new.bar  

However, I'm curious why a set of unrelated functions are all contained within the same module in the first place?

Edited to show that includes still work if public :foo is called after module_function :foo

The curly braces mean concatenation, from most significant bit (MSB) on the left down to the least significant bit (LSB) on the right. You are creating a 32-bit bus (result) whose 16 most significant bits consist of 16 copies of bit 15 (the MSB) of the a bus, and whose 16 least significant bits consist of just the a bus (this particular construction is known as sign extension, which is needed e.g. to right-shift a negative number in two's complement form and keep it negative rather than introduce zeros into the MSBits).

There is a tutorial here*, but it doesn't explain too much more than the above paragraph.

For what it's worth, the nested curly braces around a[15:0] are superfluous.

*Beware: the example within the tutorial link contains a typo when demonstrating multiple concatenations - the (2{C}} should be a {2{2}}.

Now ASP.Net MVC 5.1 got a built in support for it.

From Release Notes

We now allow passing in HTML attributes in EditorFor as an anonymous object.

For example:

@Html.EditorFor(model => model, 
              new { htmlAttributes = new { @class = "form-control" }, })

Yes, it is possible to reliably run set up and tear down methods before and after any tests in a test suite. Let me demonstrate in code:

package com.test;

import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

@RunWith(Suite.class)
@SuiteClasses({Test1.class, Test2.class})
public class TestSuite {

    @BeforeClass
    public static void setUp() {
        System.out.println("setting up");
    }

    @AfterClass
    public static void tearDown() {
        System.out.println("tearing down");
    }

}

So your Test1 class would look something like:

package com.test;

import org.junit.Test;


public class Test1 {
    @Test
    public void test1() {
        System.out.println("test1");
    }

}

...and you can imagine that Test2 looks similar. If you ran TestSuite, you would get:

setting up
test1
test2
tearing down

So you can see that the set up/tear down only run before and after all tests, respectively.

The catch: this only works if you're running the test suite, and not running Test1 and Test2 as individual JUnit tests. You mentioned you're using maven, and the maven surefire plugin likes to run tests individually, and not part of a suite. In this case, I would recommend creating a superclass that each test class extends. The superclass then contains the annotated @BeforeClass and @AfterClass methods. Although not quite as clean as the above method, I think it will work for you.

As for the problem with failed tests, you can set maven.test.error.ignore so that the build continues on failed tests. This is not recommended as a continuing practice, but it should get you functioning until all of your tests pass. For more detail, see the maven surefire documentation.

.text() will give you the actual text in between HTML tags. For example, the paragraph text in between p tags. What is interesting to note is that it will give you all the text in the element you are targeting with with your $ selector plus all the text in the children elements of that selected element. So If you have multiple p tags with text inside the body element and you do a $(body).text(), you will get all the text from all the paragraphs. (Text only, not the p tags themselves.)

.html() will give you the text and the tags. So $(body).html() will basically give you your entire page HTML page

.val() works for elements that have a value attribute, such as input. An input does not have contained text or HTML and thus .text() and .html() will both be null for input elements.

$("#myinput").attr('type') == 'checkbox'

If you need special memory alignment on the object controlled by shared_ptr, you cannot rely on make_shared, but I think it's the only one good reason about not using it.

Check Following Things

• Make Sure You Have MySQL Server Running
• Check connection with default credentials i.e. username : 'root' & password : '' [Blank Password]
• Try login phpmyadmin with same credentials
• Try to put 127.0.0.1 instead localhost or your lan IP would do too.
• Make sure you are running MySql on 3306 and if you have configured make sure to state it while making a connection

Use a global namespace like global.MYAPI = {}:

global.MYAPI._ = require('underscore')

All other posters talk about the bad pattern involved. So leaving that discussion aside, the best way to have a variable defined globally (OP's question) is through namespaces.

Tip: Development Using Namespaces

If you don't want hashes and just the first lines (subject lines):

git log --pretty=format:%s

Pickle is great but I think it's worth mentioning literal_eval from the ast module for an even lighter weight solution if you're only serializing basic python types. It's basically a "safe" version of the notorious eval function that only allows evaluation of basic python types as opposed to any valid python code.

Example:

>>> d = {}
>>> d[0] = range(10)
>>> d['1'] = {}
>>> d['1'][0] = range(10)
>>> d['1'][1] = 'hello'
>>> data_string = str(d)
>>> print data_string
{0: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], '1': {0: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 1: 'hello'}}

>>> from ast import literal_eval
>>> d == literal_eval(data_string)
True

One benefit is that the serialized data is just python code, so it's very human friendly. Compare it to what you would get with pickle.dumps:

>>> import pickle
>>> print pickle.dumps(d)
(dp0
I0
(lp1
I0
aI1
aI2
aI3
aI4
aI5
aI6
aI7
aI8
aI9
asS'1'
p2
(dp3
I0
(lp4
I0
aI1
aI2
aI3
aI4
aI5
aI6
aI7
aI8
aI9
asI1
S'hello'
p5
ss.

The downside is that as soon as the the data includes a type that is not supported by literal_ast you'll have to transition to something else like pickling.

you have error in your code unexpected token.use:

  $('#purpose').on('change', function () {
   if (this.value == '1') {
    $("#business").show();
    } else {
    $("#business").hide();
   }

   });

Demo

Update: You can narrow down the code using .toggle()

 $('#purpose').on('change', function () {
   $("#business").toggle(this.value == '1');
 });

Based on Remi answer for Python 2.7+ use this:

from __future__ import print_function
import time

# status generator
def range_with_status(total):
    """ iterate from 0 to total and show progress in console """
    import sys
    n = 0
    while n < total:
        done = '#' * (n + 1)
        todo = '-' * (total - n - 1)
        s = '<{0}>'.format(done + todo)
        if not todo:
            s += '\n'
        if n > 0:
            s = '\r' + s
        print(s, end='\r')
        sys.stdout.flush()
        yield n
        n += 1


# example for use of status generator
for i in range_with_status(50):
    time.sleep(0.2)

You're missing an ending anchor.

if(Regex.IsMatch(myString, "^[A-Za-z]{2}[0-9]{2}\z")) {
    // ...
}

EDIT: If you can have anything between an initial 2 letters and a final 2 numbers:

if(Regex.IsMatch(myString, @"^[A-Za-z]{2}.*\d{2}\z")) {
    // ...

Have a look at Select2 for Bootstrap. It should be able to do everything you need.

Another good option is Selectize.js. It feels a bit more native to Bootstrap.

Because, at least in HTML 4.01 and XHTML 1(.1), the type attribute for <script> elements is required.

In HTML 5, type is no longer required.

In fact, while you should use text/javascript in your HTML source, many servers will send the file with Content-type: application/javascript. Read more about these MIME types in RFC 4329.

Notice the difference between RFC 4329, that marked text/javascript as obsolete and recommending the use of application/javascript, and the reality in which some browsers freak out on <script> elements containing type="application/javascript" (in HTML source, not the HTTP Content-type header of the file that gets send). Recently, there was a discussion on the WHATWG mailing list about this discrepancy (HTML 5's type defaults to text/javascript), read these messages with subject Will you consider about RFC 4329?

I believe you can only add variables to the Watch window while the debugger is stopped on a breakpoint. If you set a breakpoint on a step, you should be able to enter variables into the Watch window when the breakpoint is hit. You can select the first empty row in the Watch window and enter the variable name (you may or may not get some Intellisense there, I can't remember how well that works.)

input element support only one line text:

The text state represents a one line plain text edit control for the element's value.

function stripHtml(str) {
  var tmp = document.createElement('input');
  tmp.value = str;
  return tmp.value;
}

Update: this works as expected

function stripHtml(str) {
  // Remove some tags
  str = str.replace(/<[^>]+>/gim, '');

  // Remove BB code
  str = str.replace(/\[(\w+)[^\]]*](.*?)\[\/\1]/g, '$2 ');

  // Remove html and line breaks
  const div = document.createElement('div');
  div.innerHTML = str;

  const input = document.createElement('input');
  input.value = div.textContent || div.innerText || '';

  return input.value;
}

onActivityCreated() - Deprecated

onActivityCreated() is now deprecated as Fragments Version 1.3.0-alpha02

The onActivityCreated() method is now deprecated. Code touching the fragment's view should be done in onViewCreated() (which is called immediately before onActivityCreated()) and other initialization code should be in onCreate(). To receive a callback specifically when the activity's onCreate() is complete, a LifeCycleObserver should be registered on the activity's Lifecycle in onAttach(), and removed once the onCreate() callback is received.

If you mean you want to see them like this:

WORKPLACEID NAME       ADDRESS        TELEPHONE
----------- ---------- -------------- ---------
          1 HSBC       Nugegoda Road      43434
          2 HNB Bank   Colombo Road      223423

then in SQL Plus you can set the column widths like this (for example):

column name format a10
column address format a20
column telephone format 999999999

You can also specify the line size and page size if necessary like this:

set linesize 100 pagesize 50

You do this by typing those commands into SQL Plus before running the query. Or you can put these commands and the query into a script file e.g. myscript.sql and run that. For example:

column name format a10
column address format a20
column telephone format 999999999

select name, address, telephone
from mytable;

An easy and straightforward solution using the CASE function:

SELECT CASE WHEN ( a > 0 ) THEN (a*-1) ELSE (a*-1) END AS NegativeA,
       CASE WHEN ( b > 0 ) THEN (b*-1) ELSE (b*-1) END AS PositiveB
FROM YourTableName

When the Device displays the message go to Run->Attach debbuger, then select a debbuger. it'll start the activity.

UPDATE Table1 T1 SET
T1.name = (SELECT T2.name FROM Table2 T2 WHERE T2.id = T1.id),
T1.desc = (SELECT T2.desc FROM Table2 T2 WHERE T2.id = T1.id)
WHERE T1.id IN (SELECT T2.id FROM Table2 T2 WHERE T2.id = T1.id);

It seems the problem can arise from more than one reasons. Following two steps worked when I was having same error.

1. I saved my file as MS-DOS csv. ( Earlier it was saved in as just csv , excel starter 2010 ). Opened the csv in notepad++. No coma was inconsistent (consistency as described above @Brian).
2. Noticed I was not using argument sep="," . I used and it worked ( even though that is default argument!)

1 - add &enablejsapi=1 to IFRAME SRC

2 - jQuery func:

  $('iframe#your_video')[0].contentWindow.postMessage('{"event":"command","func":"playVideo","args":""}', '*');

Works fine

Use a truly blank, valid and highly compatible SVG, based on this article:

src="data:image/svg+xml;charset=utf8,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%3E%3C/svg%3E"

It will default in size to 300x150px as any SVG does, but you can work with that in your img element default styles, as you would possibly need in any case in the practical implementation.

I just knocked this up using the Reactive Extensions and remembered this question:

public class BlockingQueue<T>
{
    private readonly Subject<T> _queue;
    private readonly IEnumerator<T> _enumerator;
    private readonly object _sync = new object();

    public BlockingQueue()
    {
        _queue = new Subject<T>();
        _enumerator = _queue.GetEnumerator();
    }

    public void Enqueue(T item)
    {
        lock (_sync)
        {
            _queue.OnNext(item);
        }
    }

    public T Dequeue()
    {
        _enumerator.MoveNext();
        return _enumerator.Current;
    }
}

Not necessarily entirely safe, but very simple.

Since the code suggested by @Pascal is deprecated as mentioned by @Jacob, I found this another way that works for me.

import org.hibernate.classic.Session;
import org.hibernate.connection.ConnectionProvider;
import org.hibernate.engine.SessionFactoryImplementor;

Session session = (Session) em.getDelegate();
SessionFactoryImplementor sfi = (SessionFactoryImplementor) session.getSessionFactory();
ConnectionProvider cp = sfi.getConnectionProvider();
Connection connection = cp.getConnection();

MacOS

add this string in file ~/.bashrc or ~/.zshrc

export ANDROID_HOME="/Users/<userlogin>/Library/Android/sdk"

The below code worked fine:

Run Keyword if    '${value1}' \ \ == \ \ '${cost1}' \ and \ \ '${value2}' \ \ == \ \ 'cost2'    LOG    HELLO

Look the answer to my previous question here

c:\> for %i in (java.exe) do @echo.   %~$PATH:i
C:\WINDOWS\system32\java.exe

This worked for me..

Check your compiled source, whether that file(e.g; ViewController.m) is added or not, in my case ViewController file was not added so it was giving me the error..

Enable the port in your system it is for CentOS 7 flow the commands below

1.firewall-cmd --get-active-zones

2.firewall-cmd --zone=dmz --add-port=50070/tcp --permanent

3.firewall-cmd --zone=public --add-port=50070/tcp --permanent

4.firewall-cmd --zone=dmz --add-port=9000/tcp --permanent

You might be just missing the column list, as the message says

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] ON

INSERT INTO [MyDB].[dbo].[Equipment]
            (COL1,
             COL2)

       COL2
FROM   [MyDBQA].[dbo].[Equipment]

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] OFF 

You can control radio button's size with css style:

style="height:35px; width:35px;"

This directly controls the radio button size.

<input type="radio" name="radio" value="value" style="height:35px; width:35px; vertical-align: middle;">

Something like this will do the trick. Don't know about performance, so do make some tests.

select
  id, name, city
from
  [stuff] s
where
1 < (select count(*) from [stuff] i where i.city = s.city and i.name = s.name)

According PEP8,I prefer to execute SQL in this way:

cur = con.cursor()
# There is no need to add single-quota to the surrounding of `%s`,
# because the MySQLdb precompile the sql according to the scheme type
# of each argument in the arguments list.
sql = "SELECT * FROM records WHERE email LIKE %s;"
args = [search, ]
cur.execute(sql, args)

In this way, you will recognize that the second argument args of execute method must be a list of arguments.

May this helps you.

Let's say your variable is always integer. In that case this is easier:

<?PHP
    $number = 4;

    echo '<script>';
    echo 'var number = ' . $number . ';';
    echo 'alert(number);';
    echo '</script>';
?>

Output:

<script>var number = 4;alert(number);</script>

Let's say your variable is not an integer, but if you try above method you will get something like this:

<script>var number = abcd;alert(number);</script>

But in JavaScript this is a syntax error.

So in PHP we have a function call json_encode that encode string to a JSON object.

<?PHP
    $number = 'abcd';

    echo '<script>';
    echo 'var number = ' . json_encode($number) . ';';
    echo 'alert(number);';
    echo '</script>';
?>

Since abcd in JSON is "abcd", it looks like this:

<script>var number = "abcd";alert(number);</script>

You can use same method for arrays:

<?PHP
    $details = [
    'name' => 'supun',
    'age' => 456,
    'weight' => '55'
    ];

    echo '<script>';
    echo 'var details = ' . json_encode($details) . ';';
    echo 'alert(details);';
    echo 'console.log(details);';
    echo '</script>';
?>

And your JavaScript code looks like this:

<script>var details = {"name":"supun","age":456,"weight":"55"};alert(details);console.log(details);</script>

Console output

As already pointed out by Nico Huysamen, finding multiple mode in Java 1.8 can be done alternatively as below.

import java.util.ArrayList;
import java.util.List;
import java.util.HashMap;
import java.util.Map;

public static void mode(List<Integer> numArr) {
    Map<Integer, Integer> freq = new HashMap<Integer, Integer>();;
    Map<Integer, List<Integer>> mode = new HashMap<Integer, List<Integer>>();

    int modeFreq = 1; //record the highest frequence
    for(int x=0; x<numArr.size(); x++) { //1st for loop to record mode
        Integer curr = numArr.get(x); //O(1)
        freq.merge(curr, 1, (a, b) -> a + b); //increment the frequency for existing element, O(1)
        int currFreq = freq.get(curr); //get frequency for current element, O(1)

        //lazy instantiate a list if no existing list, then
        //record mapping of frequency to element (frequency, element), overall O(1)
        mode.computeIfAbsent(currFreq, k -> new ArrayList<>()).add(curr);

        if(modeFreq < currFreq) modeFreq = currFreq; //update highest frequency
    }
    mode.get(modeFreq).forEach(x -> System.out.println("Mode = " + x)); //pretty print the result //another for loop to return result
}

Happy coding!

I wrote a function wrapper called bar() for barplot() to do what you are trying to do here, since I need to do similar things frequently. The Github link to the function is here. After copying and pasting it into R, you do

bar(dv = Species, 
    factors = c(Category, Reason), 
    dataframe = Reasonstats, 
    errbar = FALSE, 
    ylim=c(0, 140))  #I increased the upper y-limit to accommodate the legend. 

The one convenience is that it will put a legend on the plot using the names of the levels in your categorical variable (e.g., "Decline" and "Improved"). If each of your levels has multiple observations, it can also plot the error bars (which does not apply here, hence errbar=FALSE

As an even easier solution, you could just use:

$results = $objects.Name

Which should fill $results with an array of all the 'Name' property values of the elements in $objects.

http://momentjs.com/docs/#/displaying/unix-timestamp/

You get the number of unix seconds, not milliseconds!

You you need to multiply it with 1000 or using valueOf() and don't forget to use a formatter, since you are using a non ISO 8601 format. And if you forget to pass the formatter, the date will be parsed in the UTC timezone or as an invalid date.

moment("10/15/2014 9:00", "MM/DD/YYYY HH:mm").valueOf()

I think I found the answer:

convert(nvarchar(50), RequestID)

Here's the link where I found this info:

http://msdn.microsoft.com/en-us/library/ms187928.aspx

I still prefer the method in one line

new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(Calendar.getInstance().getTime())

Given the latest and greatest changes to .NET (+ Core) and C# 7, here is the best solution:

var ignoreCase = true;
Enum.TryParse("red", ignoreCase , out MyColours colour);

colour variable can be used within the scope of Enum.TryParse

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

For people who have narrowed down the issue to the COMMENT ON statements (as per various answers below) and who have superuser access to the source database from which the dump file is created, the simplest solution might be to prevent the comments from being included to the dump file in the first place, by removing them from the source database being dumped...

COMMENT ON EXTENSION postgis IS NULL;
COMMENT ON EXTENSION plpgsql IS NULL;
COMMENT ON SCHEMA public IS NULL;

Future dumps then won't include the COMMENT ON statements.

In Java create the pattern with Pattern p = Pattern.compile("^\\w{14}$"); for further information see the javadoc

In Xcode 5.1

Enable Done Button

• In Attributes Inspector for the UITextField in Storyboard find the field "Return Key" and select "Done"

Hide Keyboard when Done is pressed

• In Storyboard make your ViewController the delegate for the UITextField

• Add this method to your ViewController

  -(BOOL)textFieldShouldReturn:(UITextField *)textField
  {
      [textField resignFirstResponder];
      return YES;
  }
  

A straight forward way would be :

soup = BeautifulSoup(sdata)
for each_div in soup.findAll('div',{'class':'stylelist'}):
    print each_div

Make sure you take of the casing of findAll, its not findall

JavaScript is one of the worst program\scripting language ever!

"Wait" seems to be impossible in JavaScript! (Yes, like in the real life, sometimes waiting is the best option!)

I tried "while" loop and "Recursion" (a function calls itself repeatedly until ...), but JavaScript refuses to work anyway! (This is unbelievable, but anyway, see the codes below:)

while loop:

<!DOCTYPE html>

<script>

var Continue = "no";
setTimeout(function(){Continue = "yes";}, 5000);    //after 5 seconds, "Continue" is changed to "yes"

while(Continue === 'no'){};    //"while" loop will stop when "Continue" is changed to "yes" 5 seconds later

    //the problem here is that "while" loop prevents the "setTimeout()" to change "Continue" to "yes" 5 seconds later
    //worse, the "while" loop will freeze the entire browser for a brief time until you click the "stop" script execution button

</script>

Recursion:

<!DOCTYPE html>

1234

<script>

function Wait_If(v,c){
if (window[v] === c){Wait_If(v,c)};
};

Continue_Code = "no"
setTimeout(function(){Continue_Code = "yes";}, 5000);    //after 5 seconds, "Continue_Code" is changed to "yes"

Wait_If('Continue_Code', 'no');

    //the problem here, the javascript console trows the "too much recursion" error, because "Wait_If()" function calls itself repeatedly!

document.write('<br>5678');     //this line will not be executed because of the "too much recursion" error above!

</script>

I think if I set a color for a:visited it is not good: you must know the default color of tag a and every time synchronize it with a:visited.

I don't want know about the default color (it can be set in common.css of your application, or you can using outside styles).

I think it's nice solution:

HTML:

<body>
    <a class="absolute">Test of URL</a>
    <a class="unvisited absolute" target="_blank" href="google.ru">Test of URL</a>
</body>

CSS:

.absolute{
    position: absolute;
}
a.unvisited, a.unvisited:visited, a.unvisited:active{
    text-decoration: none;
    color: transparent;
}

Create two functions to handle each.

First, the canvas is drawn and the images are drawn on top of each other from point (0,0)

On button click

public void buttonMerge(View view) {

        Bitmap bigImage = BitmapFactory.decodeResource(getResources(), R.drawable.img1);
        Bitmap smallImage = BitmapFactory.decodeResource(getResources(), R.drawable.img2);
        Bitmap mergedImages = createSingleImageFromMultipleImages(bigImage, smallImage);

        img.setImageBitmap(mergedImages);
    }

Function to create an overlay.

private Bitmap createSingleImageFromMultipleImages(Bitmap firstImage, Bitmap secondImage){

    Bitmap result = Bitmap.createBitmap(firstImage.getWidth(), firstImage.getHeight(), firstImage.getConfig());
    Canvas canvas = new Canvas(result);
    canvas.drawBitmap(firstImage, 0f, 0f, null);
    canvas.drawBitmap(secondImage, 10, 10, null);
    return result;
}

Nested loop to display all rows & columns of resulting table:

$rows = mysql_num_rows($result);
$cols = mysql_num_fields($result);
for( $i = 0; $i<$rows; $i++ ) {
   for( $j = 0; $j<$cols; $j++ ) {
     echo mysql_result($result, $i, $j)."<br>";
   }
}

Can be made more complex with data decryption/decoding, error checking & html formatting before display.

Tested in MS Edge & G Chrome, PHP 5.6

I met a similar problem when I tried to store my existing repo in my Ubunt One account, I fixed it by the following steps:

Step-1: create remote repo

$ cd ~/Ubuntu\ One/
$ mkdir <project-name>
$ cd <project-name>
$ mkdir .git
$ cd .git
$ git --bare init

Step-2: add the remote

$ git remote add origin /home/<linux-user-name>/Ubuntu\ One/<project-name>/.git

Step-3: push the exising git reop to the remote

$ git push -u origin --all

Thanks for the suggestions provided here. We have found a solution and it did turn out to be related to the parameters. SQL Server was producing a convoluted execution plan when executed from the SSRS report due to 'parameter sniffing'. The workaround was to declare variables inside of the stored procedure and assign the incoming parameters to the variables. Then the query used the variables rather than the parameters. This caused the query to perform consistently whether called from SQL Server Manager or through the SSRS report.

If you are reading the dataframe from a file (say CSV or Excel) then use :

• df.read_csv(path , na_filter=False)
• df.read_excel(path , na_filter=False)

This will automatically consider the empty fields as empty strings ''

If you already have the dataframe

• df = df.replace(np.nan, '', regex=True)
• df = df.fillna('')

use bytea (or Large Objects if you absolutely have to)

<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>

That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em' as the measurement, you may want to use other units, like 'px'.

EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:

In your HTML page, containing the <p> tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:

<head>
  <style type="text/css">
    p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>

So above, all <p> elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:

<head>
  <style type="text/css">
    .container p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <div class="container">
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
  </div>
  <p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>

In the example above, only the <p> element inside the div, whose class name is 'container', will have the styles applied - and not the <p> element outside the container.

In addition to the above, you can collect your styles together and remove the style element from the <head> tag, replacing it with a <link> tag, which points to an external CSS file. This external file is where you'd now put your <p> tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.

You can't create tags with Dockerfiles but you can create multiple tags on your images via the command line.

Use this to list your image ids:

$ docker images

Then tag away:

$ docker tag 9f676bd305a4 ubuntu:13.10
$ docker tag 9f676bd305a4 ubuntu:saucy
$ docker tag eb601b8965b8 ubuntu:raring
...

select time, coalesce(count(case when activities = 3 then 1 end), 0) as count
from MyTable
group by time

SQL Fiddle Example

Output:

|  TIME | COUNT |
-----------------
| 13:00 |     2 |
| 13:15 |     2 |
| 13:30 |     0 |
| 13:45 |     1 |

If you want to count all the activities in one query, you can do:

select time, 
    coalesce(count(case when activities = 1 then 1 end), 0) as count1,
    coalesce(count(case when activities = 2 then 1 end), 0) as count2,
    coalesce(count(case when activities = 3 then 1 end), 0) as count3,
    coalesce(count(case when activities = 4 then 1 end), 0) as count4,
    coalesce(count(case when activities = 5 then 1 end), 0) as count5
from MyTable
group by time

The advantage of this over grouping by activities, is that it will return a count of 0 even if there are no activites of that type for that time segment.

Of course, this will not return rows for time segments with no activities of any type. If you need that, you'll need to use a left join with table that lists all the possible time segments.

Let me know if this is what you need. Or some thing is missing. I went through the other answers and found that jquery has been used . I took it on assumption that you need css solution . If I am missing any more point please mention :)

Code:

if [[ -e $1 && ! -e $2 ]]; then
   mkdir --parents --verbose -- "$(dirname -- "$2")"
fi
mv --verbose -- "$1" "$2"

Example:

arguments: "d1" "d2/sub"

mkdir: created directory 'd2'
renamed 'd1' -> 'd2/sub'

The QueryString collection is used to retrieve the variable values in the HTTP query string.

The HTTP query string is specified by the values following the question mark (?), like this:

Link with a query string

The line above generates a variable named txt with the value "this is a query string test".

Query strings are also generated by form submission, or by a user typing a query into the address bar of the browser.

And see this sample : http://www.codeproject.com/Articles/5876/Passing-variables-between-pages-using-QueryString

refer this : http://www.dotnetperls.com/querystring

you can collect More details in google .

It's really a matter of opinion. In your example, System.out.println(5) would be slightly more efficient, as you only refer to the number once and never change it. As was said in a comment, int is a primitive type and not a reference - thus it doesn't take up much space. However, you might want to set actual reference variables to null only if they are used in a very complicated method. All local reference variables are garbage collected when the method they are declared in returns.

You can also use unlist(), which is often useful for handling lists:

> mylist <- list(A = c(1:3), B = c(4:6), C = c(7:9))

> mylist
$A
[1] 1 2 3

$B
[1] 4 5 6

$C
[1] 7 8 9

> unlist(mylist)
A1 A2 A3 B1 B2 B3 C1 C2 C3 
 1  2  3  4  5  6  7  8  9 

> length(unlist(mylist))
[1] 9

unlist() is a simple way of executing other functions on lists as well, such as:

> sum(mylist)
Error in sum(mylist) : invalid 'type' (list) of argument

> sum(unlist(mylist))
[1] 45

String.prototype.replaceAll=function(obj,keydata='key'){
 const keys=keydata.split('key');
return Object.entries(obj).reduce((a,[key,val])=> a.replace(new RegExp(`${keys[0]}${key}${keys[1]}`,'g'),val),this)
}

const data='hids dv sdc sd {yathin} {ok}'
console.log(data.replaceAll({yathin:12,ok:'hi'},'{key}'))

String.prototype.replaceAll=function(keydata,obj){ const keys=keydata.split('key'); return Object.entries(obj).reduce((a,[key,val])=> a.replace(${keys[0]}${key}${keys[1]},val),this) }

const data='hids dv sdc sd ${yathin} ${ok}' console.log(data.replaceAll('${key}',{yathin:12,ok:'hi'}))

• Left mouse click on the bulb of error line
• Click Edit Include path
• Then this window popup

• Just set Compiler path

If the value is a String, then this might work: map.entrySet().stream().collect(Collectors.toMap(e -> e.getKey(), e -> Optional.ofNullable(e.getValue()).orElse("")))

If you just need to set precision quantity and round the value, the right way to do this is use it's own object for this.

BigDecimal value = new BigDecimal("10.0001");
value = value.setScale(4, RoundingMode.HALF_UP);
System.out.println(value); //the return should be "10.0001"

One of the pillars of Oriented Object Programming (OOP) is "encapsulation", this pillar also says that an object should deal with it's own operations, like in this way:

I got the same problem when trying to create a database using Code First(without database approach). The problem is that EF doesn't have enough permissions to create a database for you.

So I worked my way up using the Code First(using an existing database approach).

Steps :

1. Create a database in the Sql server management studio(preferably without tables).
2. Now back on visual studio, add a connection of the newly created database in the server explorer.
3. Now use the connection string of the database and add it in the app.config with a name like "Default Connection".

4. Now in the Context class, create a constructor for it and extend it from base class and pass the name of the connection string as a parameter. Just like,

   public class DummyContext : DbContext
   {
     public DummyContext() : base("name=DefaultConnection")
     {
     }  
   }
   

5.And now run your code and see the tables getting added to the database provided.

Thanks Jason Rogers's answer first.

In Android && cpp should be this:

const char *nativeString = env->GetStringUTFChars(javaString, nullptr);

// use your string

env->ReleaseStringUTFChars(javaString, nativeString);

Can fix this errors:

1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'

2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'

3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'

4.add "env->DeleteLocalRef(nativeString);" at end.

This is what i've done works like a charm

            private static int _x=0, _y=0;
        private static Point _point;
        public static Point LocationInForm(Control c)
        {
            if (c.Parent == null) 
            {
                _x += c.Location.X;
                _y += c.Location.Y;
                _point = new Point(_x, _y);
                _x = 0; _y = 0;
                return _point;
            }
            else if ((c.Parent is System.Windows.Forms.Form))
            {
                _point = new Point(_x, _y);
                _x = 0; _y = 0;
                return _point;
            }
            else 
            {
                _x += c.Location.X;
                _y += c.Location.Y;
                LocationInForm(c.Parent);
            }
            return new Point(1,1);
        }

You have to catch the SIGINT signal (we are talking POSIX right?)

See @Gab Royer´s answer for sigaction.

Example:

#include <signal.h>
#include <stdlib.h>
#include <stdio.h>

void my_handler(sig_t s){
           printf("Caught signal %d\n",s);
           exit(1); 

}

int main(int argc,char** argv)
{
   signal (SIGINT,my_handler);

   while(1);
   return 0;

}

You can use Array.sort using a custom function as parameter to define your sorting mecanism.

In your example, it would give :

var Data = [
    {id_list:1, name:'Nick',token:'312312'},{id_list:2,name:'John',token:'123123'}
]

Data.sort(function(a, b){
    return a.name < b.name ? -1 : a.name > b.name ? 1 : 0;
});

alert("First name is : " + Data[0].name); // alerts 'John'
alert("Second name is : " + Data[1].name); // alerts 'Nick'

The sort function must return either -1 if a should come before b, 1 if a should come after b and 0 if both are equal. It's up to you to define the right logic in your sorting function to sort the array.

Edit : Missed the last part of your question where you want to know the index. You would have to loop through the array to find that as others have said.

Regular grammar is either right or left linear, whereas context free grammar is basically any combination of terminals and non-terminals. Hence you can see that regular grammar is a subset of context-free grammar.

So for a palindrome for instance, is of the form,

S->ABA
A->something
B->something

You can clearly see that palindromes cannot be expressed in regular grammar since it needs to be either right or left linear and as such cannot have a non-terminal on both side.

Since regular grammars are non-ambiguous, there is only one production rule for a given non-terminal, whereas there can be more than one in the case of a context-free grammar.

Martin Porter's official page contains a Porter Stemmer in PHP as well as other languages.

If you're really serious about good stemming though you're going to need to start with something like the Porter Algorithm, refine it by adding rules to fix incorrect cases common to your dataset, and then finally add a lot of exceptions to the rules. This can be easily implemented with key/value pairs (dbm/hash/dictionaries) where the key is the word to look up and the value is the stemmed word to replace the original. A commercial search engine I worked on once ended up with 800 some exceptions to a modified Porter algorithm.

My requirements were a bit stricter:

• I had to retain case info (the strings are paths to files displayed to the user, but it's a windows app so internally all operations must be case insensitive)
• I needed keys to be as small as possible (it did make a difference in memory performance, chopped off 110 mb out of 370). This meant that caching lowercase version of keys is not an option.
• I needed creation of the data structures to be as fast as possible (again made a difference in performance, speed this time). I had to go with a builtin

My initial thought was to substitute our clunky Path class for a case insensitive unicode subclass - but:

• proved hard to get that right - see: A case insensitive string class in python
• turns out that explicit dict keys handling makes code verbose and messy - and error prone (structures are passed hither and thither, and it is not clear if they have CIStr instances as keys/elements, easy to forget plus some_dict[CIstr(path)] is ugly)

So I had finally to write down that case insensitive dict. Thanks to code by @AaronHall that was made 10 times easier.

Implicit vs explicit is still a problem, but once dust settles, renaming of attributes/variables to start with ci (and a big fat doc comment explaining that ci stands for case insensitive) I think is a perfect solution - as readers of the code must be fully aware that we are dealing with case insensitive underlying data structures. This will hopefully fix some hard to reproduce bugs, which I suspect boil down to case sensitivity.

Comments/corrections welcome :)

For file and directory search purpose I would want to offer use specialized multithreading .NET library that possess a wide search opportunities and works very fast.

All information about library you can find on GitHub: https://github.com/VladPVS/FastSearchLibrary

If you want to download it you can do it here: https://github.com/VladPVS/FastSearchLibrary/releases

If you have any questions please ask them.

It is one demonstrative example how you can use it:

class Searcher
{
    private static object locker = new object(); 

    private FileSearcher searcher;

    List<FileInfo> files;

    public Searcher()
    {
        files = new List<FileInfo>(); // create list that will contain search result
    }

    public void Startsearch()
    {
        CancellationTokenSource tokenSource = new CancellationTokenSource();
        // create tokenSource to get stop search process possibility

        searcher = new FileSearcher(@"C:\", (f) =>
        {
            return Regex.IsMatch(f.Name, @".*[Dd]ragon.*.jpg$");
        }, tokenSource);  // give tokenSource in constructor


        searcher.FilesFound += (sender, arg) => // subscribe on FilesFound event
        {
            lock (locker) // using a lock is obligatorily
            {
                arg.Files.ForEach((f) =>
                {
                    files.Add(f); // add the next received file to the search results list
                    Console.WriteLine($"File location: {f.FullName}, \nCreation.Time: {f.CreationTime}");
                });

                if (files.Count >= 10) // one can choose any stopping condition
                    searcher.StopSearch();
            }
        };

        searcher.SearchCompleted += (sender, arg) => // subscribe on SearchCompleted event
        {
            if (arg.IsCanceled) // check whether StopSearch() called
                Console.WriteLine("Search stopped.");
            else
                Console.WriteLine("Search completed.");

            Console.WriteLine($"Quantity of files: {files.Count}"); // show amount of finding files
        };

        searcher.StartSearchAsync();
        // start search process as an asynchronous operation that doesn't block the called thread
    }
}

To solve such kind of problems I created library in swift which is called Atributika.

let str = "<r>first</r><g>second</g><b>third</b>".style(tags:
        Style("r").foregroundColor(.red),
        Style("g").foregroundColor(.green),
        Style("b").foregroundColor(.blue)).attributedString

label.attributedText = str

You can find it here https://github.com/psharanda/Atributika

Tokenize the strings with the dot as delimiter and then compare the integer translation side by side, beginning from the left.

This is due because of the items id being the same. On change fires only if a different item id is detected on select.

So you have 2 options: First is to make sure that each items have a unique id when retrieving datas from ajax.

Second is to trigger a rand number at formatSelection for the selected item.

function getRandomInt(min, max) {
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

.

formatSelection: function(item) {item.id =getRandomInt(1,200)}

This is the fix that worked for me. There is invalid mime or bad characterset being sent with your json data causing that errror. Add the charset like this to help it from getting confused:

$.ajax({
  url:url,
  type:"POST",
  data:data,
  contentType:"application/json; charset=utf-8",
  dataType:"json",
  success: function(){
  ...
  }
});

Based on @ofer.sheffer answer, this is the CMD variant for adding an affix (this is not the question, but this page is still the #1 google result if you search affix). It is a bit different because of the extension.

for %a in (*.*) do ren "%~a" "%~na-affix%~xa"

You can change the "-affix" part.

A 32 bit floating point number has 23 + 1 bits of mantissa and an 8 bit exponent (-126 to 127 is used though) so the largest number you can represent is:

(1 + 1 / 2 + ... 1 / (2 ^ 23)) * (2 ^ 127) = 
(2 ^ 23 + 2 ^ 23 + .... 1) * (2 ^ (127 - 23)) = 
(2 ^ 24 - 1) * (2 ^ 104) ~= 3.4e38

This will also checks in leap year. This is pure regex, so it's faster than any lib (also faster than moment.js). But if you gonna use a lot of dates in ur code, I do recommend to use moment.js

var dateRegex = /^(?=\d)(?:(?:31(?!.(?:0?[2469]|11))|(?:30|29)(?!.0?2)|29(?=.0?2.(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(?:\x20|$))|(?:2[0-8]|1\d|0?[1-9]))([-.\/])(?:1[012]|0?[1-9])\1(?:1[6-9]|[2-9]\d)?\d\d(?:(?=\x20\d)\x20|$))?(((0?[1-9]|1[012])(:[0-5]\d){0,2}(\x20[AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2})?$/;

console.log(dateRegex.test('21/01/1986'));

Bear in mind the consequences

SELECT REPLACE(REPLACE('TEST123','123','456'),'45','89') FROM DUAL;

will replace the 123 with 456, then find that it can replace the 45 with 89. For a function that had an equivalent result, it would have to duplicate the precedence (ie replacing the strings in the same order).

Similarly, taking a string 'ABCDEF', and instructing it to replace 'ABC' with '123' and 'CDE' with 'xyz' would still have to account for a precedence to determine whether it went to '123EF' or ABxyzF'.

In short, it would be difficult to come up with anything generic that would be simpler than a nested REPLACE (though something that was more of a sprintf style function would be a useful addition).

you have the print_r function DOC

At first open terminal/command line then go to your project directory, now install nodemon by using command npm install nodemon --save-dev this command will make sure it saved as developer dependency. If you are working with expressjs then in your package file it will look like

{
  "name": "expressjs-app",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "cookie-parser": "~1.4.4",
    "debug": "~2.6.9",
    "express": "~4.16.1",
    "http-errors": "~1.6.3",
    "morgan": "~1.9.1",
    "pug": "^2.0.4"
  },
  "devDependencies": {
    "nodemon": "^2.0.3"
  }
}

now modify the "start" value in your package.json file, for production we will use the exsiting value but for development will use nodemon to track the changes in source file without restarting server. There for new value for start is "start": "if [[$NODE_ENV=='production']]; then node ./bin/www; else nodemon ./bin/www; fi"

final package.json file will look like

{
  "name": "expressjs-app",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "if [[$NODE_ENV=='production']]; then node ./bin/www; else nodemon ./bin/www; fi"
  },
  "dependencies": {
    "cookie-parser": "~1.4.4",
    "debug": "~2.6.9",
    "express": "~4.16.1",
    "http-errors": "~1.6.3",
    "morgan": "~1.9.1",
    "pug": "^2.0.4"
  },
  "devDependencies": {
    "nodemon": "^2.0.3"
  }
}

to uninstall nodemon jusy simply run the command npm uninstall nodemon

After doing a git fetch, do a git log HEAD..origin/master to show the log entries between your last common commit and the origin's master branch. To show the diffs, use either git log -p HEAD..origin/master to show each patch, or git diff HEAD...origin/master (three dots not two) to show a single diff.

There normally isn't any need to undo a fetch, because doing a fetch only updates the remote branches and none of your branches. If you're not prepared to do a pull and merge in all the remote commits, you can use git cherry-pick to accept only the specific remote commits you want. Later, when you're ready to get everything, a git pull will merge in the rest of the commits.

Update: I'm not entirely sure why you want to avoid the use of git fetch. All git fetch does is update your local copy of the remote branches. This local copy doesn't have anything to do with any of your branches, and it doesn't have anything to do with uncommitted local changes. I have heard of people who run git fetch in a cron job because it's so safe. (I wouldn't normally recommend doing that, though.)

So you want to fire Ajax calls to the servlet? For that you need the XMLHttpRequest object in JavaScript. Here's a Firefox compatible example:

<script>
    var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function() {
        if (xhr.readyState == 4) {
            var data = xhr.responseText;
            alert(data);
        }
    }
    xhr.open('GET', '${pageContext.request.contextPath}/myservlet', true);
    xhr.send(null);
</script>

This is however very verbose and not really crossbrowser compatible. For the best crossbrowser compatible way of firing ajaxical requests and traversing the HTML DOM tree, I recommend to grab jQuery. Here's a rewrite of the above in jQuery:

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>
    $.get('${pageContext.request.contextPath}/myservlet', function(data) {
        alert(data);
    });
</script>

Either way, the Servlet on the server should be mapped on an url-pattern of /myservlet (you can change this to your taste) and have at least doGet() implemented and write the data to the response as follows:

String data = "Hello World!";
response.setContentType("text/plain");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(data);

This should show Hello World! in the JavaScript alert.

You can of course also use doPost(), but then you should use 'POST' in xhr.open() or use $.post() instead of $.get() in jQuery.

Then, to show the data in the HTML page, you need to manipulate the HTML DOM. For example, you have a

<div id="data"></div>

in the HTML where you'd like to display the response data, then you can do so instead of alert(data) of the 1st example:

document.getElementById("data").firstChild.nodeValue = data;

In the jQuery example you could do this in a more concise and nice way:

$('#data').text(data);

To go some steps further, you'd like to have an easy accessible data format to transfer more complex data. Common formats are XML and JSON. For more elaborate examples on them, head to How to use Servlets and Ajax?

I believe I have found a better solution. The idea to change the function to python universal function (see documentation), which can exercise parallel computation under the hood.

One can write his own customised ufunc in C, which surely is more efficient, or by invoking np.frompyfunc, which is built-in factory method. After testing, this is more efficient than np.vectorize:

f = lambda x, y: x * y
f_arr = np.frompyfunc(f, 2, 1)
vf = np.vectorize(f)
arr = np.linspace(0, 1, 10000)

%timeit f_arr(arr, arr) # 307ms
%timeit f_arr(arr, arr) # 450ms

I have also tested larger samples, and the improvement is proportional. For comparison of performances of other methods, see this post

1.

first of all Port 80(or what ever you are using) and 443 must be allow for both TCP and UDP packets. To do this, create 2 inbound rules for TPC and UDP on Windows Firewall for port 80 and 443. (or you can disable your whole firewall for testing but permanent solution if allow inbound rule)

2.

If you are using WAMPServer 3 See bottom of answer

For WAMPServer versions <= 2.5

You need to change the security setting on Apache to allow access from anywhere else, so edit your httpd.conf file.

Change this section from :

#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

To :

#   onlineoffline tag - don't remove
    Order Allow,Deny
      Allow from all

if "Allow from all" line not work for your then use "Require all granted" then it will work for you.

WAMPServer 3 has a different method

In version 3 and > of WAMPServer there is a Virtual Hosts pre defined for localhost so dont amend the httpd.conf file at all, leave it as you found it.

Using the menus, edit the httpd-vhosts.conf file.

It should look like this :

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot D:/wamp/www
    <Directory  "D:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require local
    </Directory>
</VirtualHost>

Amend it to

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot D:/wamp/www
    <Directory  "D:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Note:if you are running wamp for other than port 80 then VirtualHost will be like VirtualHost *:86.(86 or port whatever you are using) instead of VirtualHost *:80

3. Dont forget to restart All Services of Wamp or Apache after making this change

In my case I received this exception even when all parameter values were correctly supplied but the type of command was not specified :

cmd.CommandType = System.Data.CommandType.StoredProcedure;

This is obviously not the case in the question above, but exception description is not very clear in this case, so I decided to specify that.

Having seen a large amount of issues with bitmaps incorrectly scaling when converted to a BitmapDrawable, the general way to convert should be:

Drawable d = new BitmapDrawable(getResources(), bitmap);

Without the Resources reference, the bitmap may not render properly, even when scaled correctly. There are numerous questions on here which would be solved simply by using this method rather than a straight call with only the bitmap argument.

A bit late to the party, but JQuery change inner text but preserve html has at least one approach not mentioned here:

var $td = $("#demoTable td");
$td.html($td.html().replace('Tap on APN and Enter', 'new text'));

Without fixing the text, you could use (snother)[https://stackoverflow.com/a/37828788/1587329]:

var $a = $('#demoTable td');
var inner = '';
$a.children.html().each(function() {
    inner = inner + this.outerHTML;
});
$a.html('New text' + inner);

You can define attribute as BINARY or use INSTR or STRCMP to perform your search.

It's there to enforce some initialization logic required by all implementations of your abstract class, or any methods you have implemented on your abstract class (not all the methods on your abstract class have to be abstract, some can be implemented).

Any class which inherits from your abstract base class will be obliged to call the base constructor.

If using Postgres, create sequence manually with name 'hibernate_sequence'. It will work.

For Error: 'opts' is deprecated. Use theme() instead. (Defunct; last used in version 0.9.1)' I replaced opts(title = "Boxplot - Candidate's Tweet Scores") with labs(title = "Boxplot - Candidate's Tweet Scores"). It worked!

If you're using Python 2.x, try installing a urllib2 opener. That should print out your headers, although you may have to combine that with other openers you're using to hit the HTTPS.

import urllib2
urllib2.install_opener(urllib2.build_opener(urllib2.HTTPHandler(debuglevel=1)))
urllib2.urlopen(url)

Modify to suit your specifics, or make more generic as needed:

Private Sub CopyItOver()
  Set NewBook = Workbooks.Add
  Workbooks("Whatever.xlsx").Worksheets("output").Range("A1:K10").Copy
  NewBook.Worksheets("Sheet1").Range("A1").PasteSpecial (xlPasteValues)
  NewBook.SaveAs FileName:=NewBook.Worksheets("Sheet1").Range("E3").Value
End Sub

Use this line to get the division behavior you want:

from __future__ import division

Alternatively, you could use modulus:

if (a % b) == 0: #do something

BATCH may not be able to do this, but you can use JScript or VBScript if you don't want to use tools that are not installed by default with Windows.

The first example on this page downloads a binary file in VBScript: http://www.robvanderwoude.com/vbstech_internet_download.php

This SO answer downloads a file using JScript (IMO, the better language): Windows Script Host (jscript): how do i download a binary file?

Your batch script can then just call out to a JScript or VBScript that downloads the file.

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

sudo python setup.py install

Twitter now has a sass-ready version of bootstrap with gem included, so it is easier than ever to add it to Rails.

Simply add to your gemfile the following:

gem 'sass-rails', '>= 3.2' # sass-rails needs to be higher than 3.2
gem 'bootstrap-sass', '~> 3.1.1'

bundle install and restart your server to make the files available through the pipeline.

There is also support for compass and sass-only: https://github.com/twbs/bootstrap-sass

If you aren't dynamically loading scripts or marking them as defer or async, then scripts are loaded in the order encountered in the page. It doesn't matter whether it's an external script or an inline script - they are executed in the order they are encountered in the page. Inline scripts that come after external scripts are held until all external scripts that came before them have loaded and run.

Async scripts (regardless of how they are specified as async) load and run in an unpredictable order. The browser loads them in parallel and it is free to run them in whatever order it wants.

There is no predictable order among multiple async things. If one needed a predictable order, then it would have to be coded in by registering for load notifications from the async scripts and manually sequencing javascript calls when the appropriate things are loaded.

When a script tag is inserted dynamically, how the execution order behaves will depend upon the browser. You can see how Firefox behaves in this reference article. In a nutshell, the newer versions of Firefox default a dynamically added script tag to async unless the script tag has been set otherwise.

A script tag with async may be run as soon as it is loaded. In fact, the browser may pause the parser from whatever else it was doing and run that script. So, it really can run at almost any time. If the script was cached, it might run almost immediately. If the script takes awhile to load, it might run after the parser is done. The one thing to remember with async is that it can run anytime and that time is not predictable.

A script tag with defer waits until the entire parser is done and then runs all scripts marked with defer in the order they were encountered. This allows you to mark several scripts that depend upon one another as defer. They will all get postponed until after the document parser is done, but they will execute in the order they were encountered preserving their dependencies. I think of defer like the scripts are dropped into a queue that will be processed after the parser is done. Technically, the browser may be downloading the scripts in the background at any time, but they won't execute or block the parser until after the parser is done parsing the page and parsing and running any inline scripts that are not marked defer or async.

Here's a quote from that article:

script-inserted scripts execute asynchronously in IE and WebKit, but synchronously in Opera and pre-4.0 Firefox.

The relevant part of the HTML5 spec (for newer compliant browsers) is here. There is a lot written in there about async behavior. Obviously, this spec doesn't apply to older browsers (or mal-conforming browsers) whose behavior you would probably have to test to determine.

A quote from the HTML5 spec:

Then, the first of the following options that describes the situation must be followed:

If the element has a src attribute, and the element has a defer attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element must be added to the end of the list of scripts that will execute when the document has finished parsing associated with the Document of the parser that created the element.

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element does not have a src attribute, and the element has been flagged as "parser-inserted", and the Document of the HTML parser or XML parser that created the script element has a style sheet that is blocking scripts The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

Set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, does not have an async attribute, and does not have the "force-async" flag set The element must be added to the end of the list of scripts that will execute in order as soon as possible associated with the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must run the following steps:

If the element is not now the first element in the list of scripts that will execute in order as soon as possible to which it was added above, then mark the element as ready but abort these steps without executing the script yet.

Execution: Execute the script block corresponding to the first script element in this list of scripts that will execute in order as soon as possible.

Remove the first element from this list of scripts that will execute in order as soon as possible.

If this list of scripts that will execute in order as soon as possible is still not empty and the first entry has already been marked as ready, then jump back to the step labeled execution.

If the element has a src attribute The element must be added to the set of scripts that will execute as soon as possible of the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must execute the script block and then remove the element from the set of scripts that will execute as soon as possible.

Otherwise The user agent must immediately execute the script block, even if other scripts are already executing.

What about Javascript module scripts, type="module"?

Javascript now has support for module loading with syntax like this:

<script type="module">
  import {addTextToBody} from './utils.mjs';

  addTextToBody('Modules are pretty cool.');
</script>

Or, with src attribute:

<script type="module" src="http://somedomain.com/somescript.mjs">
</script>

All scripts with type="module" are automatically given the defer attribute. This downloads them in parallel (if not inline) with other loading of the page and then runs them in order, but after the parser is done.

Module scripts can also be given the async attribute which will run inline module scripts as soon as possible, not waiting until the parser is done and not waiting to run the async script in any particular order relative to other scripts.

There's a pretty useful timeline chart that shows fetch and execution of different combinations of scripts, including module scripts here in this article: Javascript Module Loading.

I have found that this works:

$(document).ready(function(){
    $('textarea').bind('input propertychange', function() {
        //do your update here
    }

})

With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:

std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };

Or even:

std::vector<int> v(2);
v = { 34,23 };

On compilers that don't support this feature (initializer lists) yet you can emulate this with an array:

int vv[2] = { 12,43 };
std::vector<int> v(&vv[0], &vv[0]+2);

Or, for the case of assignment to an existing vector:

int vv[2] = { 12,43 };
v.assign(&vv[0], &vv[0]+2);

Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:

template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N]) { return &arr[0]+N; }

And then you can do this without having to repeat the size all over:

int vv[] = { 12,43 };
std::vector<int> v(begin(vv), end(vv));

A TreeMap is always sorted by the keys, anything else is impossible. A Comparator merely allows you to control how the keys are sorted.

If you want the sorted values, you have to extract them into a List and sort that.

In your case you can use __FILE__ variable !
It should help.
It is one of predefined.
Read more about predefined constants in PHP http://php.net/manual/en/language.constants.predefined.php

Some of us prefer languages like Java which force us to declare all the exceptions thrown by methods, instead of making them invisible as in C++ and C#.

When done properly, exceptions are superior to error return codes, if for no other reason than you don't have to propagate failures up the call chain manually.

That being said, low-level API library programming should probably avoid exception handling, and stick to error return codes.

It's been my experience that it's difficult to write clean exception handling code in C++. I end up using new(nothrow) a lot.

Use Array.pop:

var lastItem = anArray.pop();

Important : This returns the last element and removes it from the array

Here is where you went wrong:

this.result = http.get('friends.json')
                  .map(response => response.json())
                  .subscribe(result => this.result =result.json());

it should be:

http.get('friends.json')
                  .map(response => response.json())
                  .subscribe(result => this.result =result);

or

http.get('friends.json')
                  .subscribe(result => this.result =result.json());

You have made two mistakes:

1- You assigned the observable itself to this.result. When you actually wanted to assign the list of friends to this.result. The correct way to do it is:

• you subscribe to the observable. .subscribe is the function that actually executes the observable. It takes three callback parameters as follow:

  .subscribe(success, failure, complete);

for example:

.subscribe(
    function(response) { console.log("Success Response" + response)},
    function(error) { console.log("Error happened" + error)},
    function() { console.log("the subscription is completed")}
);

Usually, you take the results from the success callback and assign it to your variable. the error callback is self explanatory. the complete callback is used to determine that you have received the last results without any errors. On your plunker, the complete callback will always be called after either the success or the error callback.

2- The second mistake, you called .json() on .map(res => res.json()), then you called it again on the success callback of the observable. .map() is a transformer that will transform the result to whatever you return (in your case .json()) before it's passed to the success callback you should called it once on either one of them.

as per docs:

• "json": Evaluates the response as JSON and returns a JavaScript object. In jQuery 1.4 the JSON data is parsed in a strict manner; any malformed JSON is rejected and a parse error is thrown. (See json.org for more information on proper JSON formatting.)
• "text": A plain text string.

But as your system grows in size and functionality... i think that returning always a json is not a bad idea at all. Is more a architectural / "big scale design" matter.

You can think about returing always a JSON with two know fields : code and data. Where code is a numeric code specifying the success of the operation to be done and data is any aditional data related with the operation / service requested.

Come on, when we use a backend a service provider, any service can be checked to see if it worked well.

So i stick, to not let spring manage this, exposing hybrid returning operations (Some returns data other nothing...).. instaed make sure that your server expose a more homogeneous interface. Is more simple at the end of the day.

Easy way out is to use a condition like this ( use desired date > GETDATE()-1)

your sql statement "date specific" > GETDATE()-1

One liners that return other string if there was no match. Edit: improved version uses next function, replace "not-found" with something else if needed:

import re
res = next( (m.group(1) for m in [re.search("AAA(.*?)ZZZ", "gfgfdAAA1234ZZZuijjk" ),] if m), "not-found" )

My other method to do this, less optimal, uses regex 2nd time, still didn't found a shorter way:

import re
res = ( ( re.search("AAA(.*?)ZZZ", "gfgfdAAA1234ZZZuijjk") or re.search("()","") ).group(1) )

I use this regex in Java ^(0[1-9]|1[012])[/](0[1-9]|[12][0-9]|3[01])[/](19|[2-9][0-9])[0-9]{2}$

Works from 1900 to 9999

First you can subclass urllib2.BaseHandler or urllib2.HTTPBasicAuthHandler, and implement http_request so that each request has the appropriate Authorization header.

import urllib2
import base64

class PreemptiveBasicAuthHandler(urllib2.HTTPBasicAuthHandler):
    '''Preemptive basic auth.

    Instead of waiting for a 403 to then retry with the credentials,
    send the credentials if the url is handled by the password manager.
    Note: please use realm=None when calling add_password.'''
    def http_request(self, req):
        url = req.get_full_url()
        realm = None
        # this is very similar to the code from retry_http_basic_auth()
        # but returns a request object.
        user, pw = self.passwd.find_user_password(realm, url)
        if pw:
            raw = "%s:%s" % (user, pw)
            auth = 'Basic %s' % base64.b64encode(raw).strip()
            req.add_unredirected_header(self.auth_header, auth)
        return req

    https_request = http_request

Then if you are lazy like me, install the handler globally

api_url = "http://api.foursquare.com/"
api_username = "johndoe"
api_password = "some-cryptic-value"

auth_handler = PreemptiveBasicAuthHandler()
auth_handler.add_password(
    realm=None, # default realm.
    uri=api_url,
    user=api_username,
    passwd=api_password)
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)

Checking the Options Over Write Database worked for me :)

A complete example using schedule and multiprocessing, with on and off control and parameter to run_job() the return codes are simplified and interval is set to 10sec, change to every(2).hour.do()for 2hours. Schedule is quite impressive it does not drift and I've never seen it more than 100ms off when scheduling. Using multiprocessing instead of threading because it has a termination method.

#!/usr/bin/env python3

import schedule
import time
import datetime
import uuid

from flask import Flask, request
from multiprocessing import Process

app = Flask(__name__)
t = None
job_timer = None

def run_job(id):
    """ sample job with parameter """
    global job_timer
    print("timer job id={}".format(id))
    print("timer: {:.4f}sec".format(time.time() - job_timer))
    job_timer = time.time()

def run_schedule():
    """ infinite loop for schedule """
    global job_timer
    job_timer = time.time()
    while 1:
        schedule.run_pending()
        time.sleep(1)

@app.route('/timer/<string:status>')
def mytimer(status, nsec=10):
    global t, job_timer
    if status=='on' and not t:
        schedule.every(nsec).seconds.do(run_job, str(uuid.uuid4()))
        t = Process(target=run_schedule)
        t.start()
        return "timer on with interval:{}sec\n".format(nsec)
    elif status=='off' and t:
        if t:
            t.terminate()
            t = None
            schedule.clear()
        return "timer off\n"
    return "timer status not changed\n"

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000)

You test this by just issuing:

$ curl http://127.0.0.1:5000/timer/on
timer on with interval:10sec
$ curl http://127.0.0.1:5000/timer/on
timer status not changed
$ curl http://127.0.0.1:5000/timer/off
timer off
$ curl http://127.0.0.1:5000/timer/off
timer status not changed

Every 10sec the timer is on it will issue a timer message to console:

127.0.0.1 - - [18/Sep/2018 21:20:14] "GET /timer/on HTTP/1.1" 200 -
timer job id=b64ed165-911f-4b47-beed-0d023ead0a33
timer: 10.0117sec
timer job id=b64ed165-911f-4b47-beed-0d023ead0a33
timer: 10.0102sec

These are the options currently documented in the tests: ctrl, shift, enter and escape. These are some valid examples of key bindings:

keydown.control.shift.enter
keydown.control.esc

You can track this here while no official docs exist, but they should be out soon.

You should find the 'expect' command will do what you need it to do. Its widely available. See here for an example : http://www.thegeekstuff.com/2010/10/expect-examples/

(very rough example)

#!/usr/bin/expect
set pass "mysecret"

spawn /usr/bin/passwd

expect "password: "
send "$pass"
expect "password: "
send "$pass"

Very easy from My side:-

<html>
<head>
<script
    src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<script>
    $(document).ready(function() {
        $("input").click(function() {
            $('<input type="text" name="name" value="value"/>').appendTo('#testdiv');
        });

    });
</script>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    <div id="testdiv"></div>
    <input type="button" value="Add" />
</body>
</html>

In case the Jenkins is triggering a build by restricting it to run on a slave or any other server (you may find it in the below setting under 'configure')

then the Path to Git executable should be set as per the 'slave_server_hostname' or any other server where the git commands are executed.

How to hard reset Visual Studio instance

When developing extensions sometimes you just mess up, others someone else does. If you start getting errors loading even the most mundane extensions, these are the instructions to hard reset your instance.

Close Visual Studio (if you haven’t already).
Open the registry editor (regedit.exe)
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}_Config
Delete the %LOCALAPPDATA%\Microsoft\VisualStudio\{version} directory.

Enjoy your brand new Visual Studio instance.

• Use {version}=10.0 for Visual Studio 2010
• Use {version}=11.0 for Visual Studio 2012
• Use {version}=12.0 for Visual Studio 2013

If on the other side you want to reset the experimental hive you can do the same to with the ‘{version}Exp’ ones.

Happy coding!

Use DateTime.AddDays() method with value of -1

var yesterday = DateTime.Today.AddDays(-1);

That will give you : {6/28/2012 12:00:00 AM}

You can also use

DateTime.Now.AddDays(-1)

That will give you previous date with the current time e.g. {6/28/2012 10:30:32 AM}

I use a function for this :

private void Log (string s) {

1. Databases can handle querying tasks, so you don't have to walk over files manually. Databases can handle very complicated queries.
2. Databases can handle indexing tasks, so if tasks like get record with id = x can be VERY fast
3. Databases can handle multiprocess/multithreaded access.
4. Databases can handle access from network
5. Databases can watch for data integrity
6. Databases can update data easily (see 1) )
7. Databases are reliable
8. Databases can handle transactions and concurrent access
9. Databases + ORMs let you manipulate data in very programmer friendly way.

Prefix you literal with 0b like in

int i = 0b11111111;

Search or show all aliases

Add to your .gitconfig under [alias]:

aliases = !git config --list | grep ^alias\\. | cut -c 7- | grep -Ei --color \"$1\" "#"

Then you can do

• git aliases - show ALL aliases
• git aliases commit - only aliases containing "commit"

cast(value as int) will always work if string is a number

So, there's no way that this works:

window.onload = function(){
  <script language="JavaScript" src="http://jact.atdmt.com/jaction/JavaScriptTest"></script>
};

You can't freely drop HTML into the middle of javascript.

If you have jQuery, you can just use:

$.getScript("http://jact.atdmt.com/jaction/JavaScriptTest")

whenever you want. If you want to make sure the document has finished loading, you can do this:

$(document).ready(function() {
    $.getScript("http://jact.atdmt.com/jaction/JavaScriptTest");
});

In plain javascript, you can load a script dynamically at any time you want to like this:

var tag = document.createElement("script");
tag.src = "http://jact.atdmt.com/jaction/JavaScriptTest";
document.getElementsByTagName("head")[0].appendChild(tag);

You should check out the new Eclipse 2019-09 4.13 Quick Search feature

The new Quick Search dialog provides a convenient, simple and fast way to run a textual search across your workspace and jump to matches in your code.

The dialog provides a quick overview showing matching lines of text at a glance.
It updates as quickly as you can type and allows for quick navigation using only the keyboard.

A typical workflow starts by pressing the keyboard shortcut Ctrl+Alt+Shift+L
(or Cmd+Alt+Shift+L on Mac).
Typing a few letters updates the search result as you type.
Use Up-Down arrow keys to select a match, then hit Enter to open it in an editor.

I would do something like this:

Select count(*), productid
from products
where keyword = '$keyword'
group by productid

that will give you a list like

count(*)    productid  
----------------------
 5           12345   
 3           93884   
 9           93493    

This allows you to see how many of each distinct productid ID is associated with the keyword.

Solved my own problem. This line:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

needs to be:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));

or since Java 7:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));

        // The newInstance() call is a work around for some
        // broken Java implementations
        Class.forName("com.mysql.cj.jdbc.Driver").newInstance();

You are getting that error because when the param1 if statements are evaluated, param is always null due to being scoped variables without delayed expansion.

When parentheses are used, all the commands and variables within those parentheses are expanded. And at that time, param1 has no value making the if statements invalid. When using delayed expansion, the variables are only expanded when the command is actually called.

Also I recommend using if not defined command to determine if a variable is set.

@echo off
setlocal EnableExtensions EnableDelayedExpansion

    )
    if "!param1!"=="2" (
        REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies\ /v WriteProtect /t REG_DWORD /d 00000000

Just add overflow:hidden to the table with border-radius.

.tablewithradius {
  overflow:hidden ;
  border-radius: 15px;
}

You can simply use the most Pythonic approach (IMHO):

import os

your_path = r"d:\stuff\morestuff\furtherdown\THEFILE.txt"
path_list = your_path.split(os.sep)
print path_list

Which will give you:

['d:', 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt']

The clue here is to use os.sep instead of '\\' or '/', as this makes it system independent.

To remove colon from the drive letter (although I don't see any reason why you would want to do that), you can write:

path_list[0] = path_list[0][0]

tl;dr

java.sql.Timestamp                  
.valueOf(                           // Class-method parses SQL-style formatted date-time strings.
    "2007-11-11 12:13:14"
)                                   // Returns a `Timestamp` object.
.toInstant()                        // Converts from terrible legacy classes to modern *java.time* class.

java.sql.Timestamp.valueOf parses SQL format

If you can use the full four digits for the year, your input string of 2007-11-11 12:13:14 would be in standard SQL format assuming this value is meant to be in UTC time zone.

The java.sql.Timestamp class has a valueOf method to directly parse such strings.

String input = "2007-11-11 12:13:14" ;
java.sql.Timestamp ts = java.sql.Timestamp.valueOf( input ) ;

java.time

In Java 8 and later, the java.time framework makes it easier to verify the results. The j.s.Timestamp class has a nasty habit of implicitly applying your JVM’s current default timestamp when generating a string representation via its toString method. In contrast, the java.time classes by default use the standard ISO 8601 formats.

System.out.println( "Output: " + ts.toInstant().toString() );

You can use IIF (I think from SQL Server 2012)

SELECT IIF(B.[STAT] IS NULL, C.[EVENT DATE]+10, '-') AS [DATE]

In the Controller , one could use the below syntax

public ViewResult EditEmployee() {
    return View();
}

public ActionResult EditEmployee() {
    return View();
}

In the above example , only the return type varies . one returns ViewResult whereas the other one returns ActionResult.

ActionResult is an abstract class . It can accept:

ViewResult , PartialViewResult, EmptyResult , RedirectResult , RedirectToRouteResult , JsonResult , JavaScriptResult , ContentResult, FileContentResult , FileStreamResult , FilePathResult etc.

The ViewResult is a subclass of ActionResult.

-u: disabled by default. When activated, an error message is displayed when using an unconfigured variable.

-v: inactive by default. After activation, the original content of the information will be displayed (without variable resolution) before the information is output.

-x: inactive by default. If activated, the command content will be displayed before the command is run (after variable resolution, there is a ++ symbol).

Compare the following differences:

/ # set -v && echo $HOME
/root
/ # set +v && echo $HOME
set +v && echo $HOME
/root

/ # set -x && echo $HOME
+ echo /root
/root
/ # set +x && echo $HOME
+ set +x
/root

/ # set -u && echo $NOSET
/bin/sh: NOSET: parameter not set
/ # set +u && echo $NOSET

1. Make sure that the version of the m2e(clipse) plugin that you're running is at least 1.1.0

2. Close maven project - right click "Close Project"

3. Manualy remove all classpathentry with kind="var" in .classpath file
4. Open project

or

1. Remove maven project
2. Manualy rmeove .classpath 4 Reimport project

A common case for simply setting -fpermissive and not sweating it exists: the thoroughly-tested and working third-party library that won't compile on newer compiler versions without -fpermissive. These libraries exist, and are very likely not the application developer's problem to solve, nor in the developer's schedule budget to do it.

Set -fpermissive and move on in that case.

You have so many choices, how could you be confused :-)? The main controls are:

# \pset format
# \H
# \x
# \pset pager off

Each has options and interactions with the others. The most automatic options are:

# \x off;\pset format wrapped
# \x auto

The newer "\x auto" option switches to line-by-line display only "if needed".

-[ RECORD 1 ]---------------

The older "\pset format wrapped" is similar in that it tries to fit the data neatly on screen, but falls back to unaligned if the headers won't fit. Here's an example of wrapped:

protected void DescargarArchivo(string strRuta, string strFile)

This works for me:

function animateRotate (object,fromDeg,toDeg,duration){
    var dummy = $('<span style="margin-left:'+fromDeg+'px;">')
    $(dummy).animate({
        "margin-left":toDeg+"px"
    },{
        duration:duration,
        step: function(now,fx){
            $(object).css('transform','rotate(' + now + 'deg)');
        }
    });
};

if you want to filter the tuples you can use on this way:

select distinct (case a > b then (a,b) else (b,a) end) from pairs

the good stuff is you don't have to use group by.

Even I have the same kind of issues. This helped me a lot

$("[data-dismiss=modal]").trigger({ type: "click" });

Use the below code snippet to get bytes from csv file

protected byte[] GetCSVFileContent(string fileName)
    {
        StringBuilder sb = new StringBuilder();
        using (StreamReader sr = new StreamReader(fileName, Encoding.Default, true))
        {
            String line;
            // Read and display lines from the file until the end of 
            // the file is reached.
            while ((line = sr.ReadLine()) != null)
            {
                sb.AppendLine(line);
            }
        }
        string allines = sb.ToString();


        UTF8Encoding utf8 = new UTF8Encoding();


        var preamble = utf8.GetPreamble();

        var data = utf8.GetBytes(allines);


        return data;
    }

Call the below and save it as an attachment

           Encoding csvEncoding = Encoding.UTF8;
                   //byte[] csvFile = GetCSVFileContent(FileUpload1.PostedFile.FileName);
          byte[] csvFile = GetCSVFileContent("Your_CSV_File_NAme");


        string attachment = String.Format("attachment; filename={0}.csv", "uomEncoded");

        Response.Clear();
        Response.ClearHeaders();
        Response.ClearContent();
        Response.ContentType = "text/csv";
        Response.ContentEncoding = csvEncoding;
        Response.AppendHeader("Content-Disposition", attachment);
        //Response.BinaryWrite(csvEncoding.GetPreamble());
        Response.BinaryWrite(csvFile);
        Response.Flush();
        Response.End();

I am on MacOS, and the most convenient way for me is to using CyberDuck, which is free (also available for Windows). You can connect to your remote SSH file system and edit your file using your local editor. What CyberDuck does is download the file to a temporary place on your local OS and open it with your editor. Once you save the file, CyberDuck automatically upload it to your remote system. It seems transparent as if you are editing your remote file using your local editor. The developers of Cyberduck also make MountainDuck for mounting remote files systems.

You can try jstorage javascript plugin, it is an elegant way to maintain sessions check this http://www.jstorage.info/

include the jStorage.js script into your html

<script src="jStorage.js"></script>

Then in your javascript place the sessiontoken into the a key like this

$.jStorage.set("YOUR_KEY",session_id);

Where "YOUR_KEY" is the key using which you can access you session_id , like this:

var id = $.jStorage.get("YOUR_KEY");

This worked perfectly for me:

func switchScreen() {
    let mainStoryboard = UIStoryboard(name: "Main", bundle: Bundle.main)
    if let viewController = mainStoryboard.instantiateViewController(withIdentifier: "yourVcName") as? UIViewController {
        self.present(viewController, animated: true, completion: nil)
    }
}

in order to make sure, that you are using the latest version for your :latest tag from your registry (e.g. docker hub) you need to also pull the latest tag again. in case it changed, the diff will be downloaded and started when you docker-compose up again.

so this would be the way to go:

docker-compose stop
docker-compose rm -f
docker-compose pull   
docker-compose up -d

i glued this into an image that i run to start docker-compose and make sure images stay up-to-date: https://hub.docker.com/r/stephanlindauer/docker-compose-updater/

I'm assuming you have a typo in your get statement and that it should be test1.get(key). If so, I'm not sure why it is not returning an ArrayList unless you are not putting in the correct type in the map in the first place.

This should work:

// populate the map
Map<String, List<String>> test1 = new LinkedHashMap<String, List<String>>();
test1.put("key1", new ArrayList<String>());
test1.put("key2", new ArrayList<String>());

// loop over the set using an entry set
for( Map.Entry<String,List<String>> entry : test1.entrySet()){
  String key = entry.getKey();
  List<String>value = entry.getValue();
  // ...
}

or you can use

// second alternative - loop over the keys and get the value per key
for( String key : test1.keySet() ){
  List<String>value = test1.get(key);
  // ...
}

You should use the interface names when declaring your vars (and in your generic params) unless you have a very specific reason why you are defining using the implementation.

As others have already pointed out, the reason you are not getting the results you expect is because your JSON does not match the class structure that you are trying to deserialize into. You either need to change your JSON or change your classes. Since others have already shown how to change the JSON, I will take the opposite approach here.

To match the JSON you posted in your question, your classes should be defined like those below. Notice I've made the following changes:

1. I added a Wrapper class corresponding to the outer object in your JSON.
2. I changed the Values property of the ValueSet class from a List<Value> to a Dictionary<string, Value> since the values property in your JSON contains an object, not an array.
3. I added some additional [JsonProperty] attributes to match the property names in your JSON objects.

Class definitions:

class Wrapper
{
    [JsonProperty("JsonValues")]
    public ValueSet ValueSet { get; set; }
}

class ValueSet
{
    [JsonProperty("id")]
    public string Id { get; set; }
    [JsonProperty("values")]
    public Dictionary<string, Value> Values { get; set; }
}

class Value
{
    [JsonProperty("id")]
    public string Id { get; set; }
    [JsonProperty("diaplayName")]
    public string DisplayName { get; set; }
}

You need to deserialize into the Wrapper class, not the ValueSet class. You can then get the ValueSet from the Wrapper.

var valueSet = JsonConvert.DeserializeObject<Wrapper>(jsonString).ValueSet;

Here is a working program to demonstrate:

class Program
{
    static void Main(string[] args)
    {
        string jsonString = @"
        {
            ""JsonValues"": {
                ""id"": ""MyID"",
                ""values"": {
                    ""value1"": {
                        ""id"": ""100"",
                        ""diaplayName"": ""MyValue1""
                    },
                    ""value2"": {
                        ""id"": ""200"",
                        ""diaplayName"": ""MyValue2""
                    }
                }
            }
        }";

        var valueSet = JsonConvert.DeserializeObject<Wrapper>(jsonString).ValueSet;

        Console.WriteLine("id: " + valueSet.Id);
        foreach (KeyValuePair<string, Value> kvp in valueSet.Values)
        {
            Console.WriteLine(kvp.Key + " id: " + kvp.Value.Id);
            Console.WriteLine(kvp.Key + " name: " + kvp.Value.DisplayName);
        }
    }
}

And here is the output:

id: MyID
value1 id: 100
value1 name: MyValue1
value2 id: 200
value2 name: MyValue2

You can try to use this function if you need to round down to a specific number of decimal places

function roundDown(number, decimals) {
    decimals = decimals || 0;
    return ( Math.floor( number * Math.pow(10, decimals) ) / Math.pow(10, decimals) );
}

examples

alert(roundDown(999.999999)); // 999
alert(roundDown(999.999999, 3)); // 999.999
alert(roundDown(999.999999, -1)); // 990

Ctrl + Alt + Shift + N allows you to search for symbols, including methods.

The primary advantage of this more complicated keybinding is that is searches in all files, not just the current file as Ctrl + F12 does.

(And as always, for Mac you substitute Cmd for Ctrl for these keybindings.)

Here's a simple example:

public class ObservableClass
{
    private Int32 _Value;

    public Int32 Value
    {
        get { return _Value; }
        set
        {
            if (_Value != value)
            {
                _Value = value;
                OnValueChanged();
            }
        }
    }

    public event EventHandler ValueChanged;

    protected void OnValueChanged()
    {
        if (ValueChanged != null)
            ValueChanged(this, EventArgs.Empty);
    }
}

public class ObserverClass
{
    public ObserverClass(ObservableClass observable)
    {
        observable.ValueChanged += TheValueChanged;
    }

    private void TheValueChanged(Object sender, EventArgs e)
    {
        Console.Out.WriteLine("Value changed to " +
            ((ObservableClass)sender).Value);
    }
}

public class Program
{
    public static void Main()
    {
        ObservableClass observable = new ObservableClass();
        ObserverClass observer = new ObserverClass(observable);
        observable.Value = 10;
    }
}

Note:

• This violates a rule in that I don't unhook the observer from the observable, this is perhaps good enough for this simple example, but make sure you don't keep observers hanging off of your events like that. A way to handle this would be to make ObserverClass IDisposable, and let the .Dispose method do the opposite of the code in the constructor
• No error-checking performed, at least a null-check should be done in the constructor of the ObserverClass

I had 20.8 GB in the C:\Users\ggo\AppData\Local\Android\Sdk\system-images folder (6 android images: - android-10 - android-15 - android-21 - android-23 - android-25 - android-26 ).

I have compressed the C:\Users\ggo\AppData\Local\Android\Sdk\system-images folder.

Now it takes only 4.65 GB.

I did not encountered any problem up to now...

Compression seems to vary from 2/3 to 6, sometimes much more:
