There's no need to mess with your PYTHONPATH or sys.path here.

To properly use absolute imports in a package you should include the "root" packagename as well, e.g.:

from dirFoo.dirFoo1.foo1 import Foo1
from dirFoo.dirFoo2.foo2 import Foo2

Or you can use relative imports:

from .dirfoo1.foo1 import Foo1
from .dirfoo2.foo2 import Foo2

Practice safe computing. Simply go up one level in the hierarchy and don't use a wildcard expression:

cd ..; rm -rf -- <dir-to-remove>

The two dashes -- tell rm that <dir-to-remove> is not a command-line option, even when it begins with a dash.

Create List Of String

    public static List<string> HTMLFiles = new List<string>();

 private void Form1_Load(object sender, EventArgs e)
        {

     HTMLFiles.AddRange(Directory.GetFiles(@"C:\DataBase", "*.txt"));
            foreach (var item in HTMLFiles)
            {
                MessageBox.Show(item);
            }

}

Create an empty file __init__.py in subdirectory /lib. And add at the begin of main code

from __future__ import absolute_import 

then

import lib.BoxTime as BT
...
BT.bt_function()

or better

from lib.BoxTime import bt_function
...
bt_function()

Try this, pick or create one column and make that value required so that it's always populated such as title. A field that doesn't hold the name of the folder. Then in your filter put the filter you wanted that will select only the files you want. Then add an or to your filter, select your "required" field then set it equal to and leave the filter blank. Since all folders will have a blank in this required field your folders will show up with your files.

While existing answers definitely solve the purpose, if your'e looking to replicate nested directory structure under two different subdirectories, then you can do this

mkdir -p {main,test}/{resources,scala/com/company}

It will create following directory structure under the directory from where it is invoked

+-- main
¦   +-- resources
¦   +-- scala
¦       +-- com
¦           +-- company
+-- test
    +-- resources
    +-- scala
        +-- com
            +-- company

The example was taken from this link for creating SBT directory structure

The best answer is to add a Resources/.gitignore file under Resources containing:

# Ignore any file in this directory except for this file and *.foo files
*
!/.gitignore
!*.foo

If you are unwilling or unable to add that .gitignore file, there is an inelegant solution:

# Ignore any file but *.foo under Resources. Update this if we add deeper directories
Resources/*
!Resources/*/
!Resources/*.foo
Resources/*/*
!Resources/*/*/
!Resources/*/*.foo
Resources/*/*/*
!Resources/*/*/*/
!Resources/*/*/*.foo
Resources/*/*/*/*
!Resources/*/*/*/*/
!Resources/*/*/*/*.foo

You will need to edit that pattern if you add directories deeper than specified.

Your index.html can just do src="images/logo.png" and from sub.html you would do src="../images/logo.png"

I had a similar thing to work on, and this is how I did it.

import os

rootdir = os.getcwd()

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        #print os.path.join(subdir, file)
        filepath = subdir + os.sep + file

        if filepath.endswith(".html"):
            print (filepath)

Hope this helps.

You can try this function (PHP 7 required)

function getDirectories(string $path) : array
{
    $directories = [];
    $items = scandir($path);
    foreach ($items as $item) {
        if($item == '..' || $item == '.')
            continue;
        if(is_dir($path.'/'.$item))
            $directories[] = $item;
    }
    return $directories;
}

Check this code :

Set objFSO = CreateObject("Scripting.FileSystemObject") 

objStartFolder = "C:\Folder1\"

Set objFolder = objFSO.GetFolder(objStartFolder)

Set colFiles = objFolder.Files

For Each objFile in colFiles 
    strFileName = objFile.Name

    If objFSO.GetExtensionName(strFileName) = "pdf" Then 
        Wscript.Echo objFile.Name 
    End If
Next

ShowSubfolders objFSO.GetFolder(objStartFolder)

Sub ShowSubFolders(Folder)

    For Each Subfolder in Folder.SubFolders 
        Set objFolder = objFSO.GetFolder(Subfolder.Path) 
        Set colFiles = objFolder.Files 
        for each Files in colFiles 
            if LCase(InStr(1,Files, ".pdf")) > 1 then Wscript.Echo Files 
        next
        ShowSubFolders Subfolder 
    Next 
End Sub

Do you mean immediate subdirectories, or every directory right down the tree?

Either way, you could use os.walk to do this:

os.walk(directory)

will yield a tuple for each subdirectory. Ths first entry in the 3-tuple is a directory name, so

[x[0] for x in os.walk(directory)]

should give you all of the subdirectories, recursively.

Note that the second entry in the tuple is the list of child directories of the entry in the first position, so you could use this instead, but it's not likely to save you much.

However, you could use it just to give you the immediate child directories:

next(os.walk('.'))[1]

Or see the other solutions already posted, using os.listdir and os.path.isdir, including those at "How to get all of the immediate subdirectories in Python".

For files in current working directory without specifying a path

Python 2.7:

import os
os.listdir('.')

Python 3.x:

import os
os.listdir()

I don't have enough reputation to comment on any answer. In one of the comments, someone has asked how to ignore the hidden folders in the list. Below is how you can do this.

dir /b /AD-H

git clone --filter from git 2.19 now works on GitHub (tested 2021-01-14, git 2.30.0)

This option was added together with an update to the remote protocol, and it truly prevents objects from being downloaded from the server.

E.g., to clone only objects required for d1 of this minimal test repository: https://github.com/cirosantilli/test-git-partial-clone I can do:

git clone \
  --depth 1  \
  --filter=blob:none  \
  --sparse \
  https://github.com/cirosantilli/test-git-partial-clone \
;
cd test-git-partial-clone
git sparse-checkout init --cone
git sparse-checkout set d1

Here's a less minimal and more realistic version at https://github.com/cirosantilli/test-git-partial-clone-big-small

git clone \
  --depth 1  \
  --filter=blob:none  \
  --sparse \
  https://github.com/cirosantilli/test-git-partial-clone-big-small \
;
cd test-git-partial-clone
git sparse-checkout init --cone
git sparse-checkout set small

That repository contains:

• a big directory with 10 10MB files
• a small directory with 1000 files of size one byte

All contents are pseudo-random and therefore incompressible.

Clone times on my 36.4 Mbps internet:

• full: 24s
• partial: "instantaneous"

The sparse-checkout part is also needed unfortunately. You can also only download certain files with the much more understandable:

git clone \
  --depth 1  \
  --filter=blob:none  \
  --no-checkout \
  https://github.com/cirosantilli/test-git-partial-clone \
;
cd test-git-partial-clone
git checkout master -- di

but that method for some reason downloads files one by one very slowly, making it unusable unless you have very few files in the directory.

Analysis of the objects in the minimal repository

The clone command obtains only:

• a single commit object with the tip of the master branch
• all 4 tree objects of the repository:
  • toplevel directory of commit
  • the the three directories d1, d2, master

Then, the git sparse-checkout set command fetches only the missing blobs (files) from the server:

• d1/a
• d1/b

Even better, later on GitHub will likely start supporting:

  --filter=blob:none \
  --filter=tree:0 \

where --filter=tree:0 from Git 2.20 will prevent the unnecessary clone fetch of all tree objects, and allow it to be deferred to checkout. But on my 2020-09-18 test that fails with:

fatal: invalid filter-spec 'combine:blob:none+tree:0'

presumably because the --filter=combine: composite filter (added in Git 2.24, implied by multiple --filter) is not yet implemented.

I observed which objects were fetched with:

git verify-pack -v .git/objects/pack/*.pack

as mentioned at: How to list ALL git objects in the database? It does not give me a super clear indication of what each object is exactly, but it does say the type of each object (commit, tree, blob), and since there are so few objects in that minimal repo, I can unambiguously deduce what each object is.

git rev-list --objects --all did produce clearer output with paths for tree/blobs, but it unfortunately fetches some objects when I run it, which makes it hard to determine what was fetched when, let me know if anyone has a better command.

TODO find GitHub announcement that saying when they started supporting it. https://github.blog/2020-01-17-bring-your-monorepo-down-to-size-with-sparse-checkout/ from 2020-01-17 already mentions --filter blob:none.

git sparse-checkout

I think this command is meant to manage a settings file that says "I only care about these subtrees" so that future commands will only affect those subtrees. But it is a bit hard to be sure because the current documentation is a bit... sparse ;-)

It does not, by itself, prevent the fetching of blobs.

If this understanding is correct, then this would be a good complement to git clone --filter described above, as it would prevent unintentional fetching of more objects if you intend to do git operations in the partial cloned repo.

When I tried on Git 2.25.1:

git clone \
  --depth 1 \
  --filter=blob:none \
  --no-checkout \
  https://github.com/cirosantilli/test-git-partial-clone \
;
cd test-git-partial-clone
git sparse-checkout init

it didn't work because the init actually fetched all objects.

However, in Git 2.28 it didn't fetch the objects as desired. But then if I do:

git sparse-checkout set d1

d1 is not fetched and checked out, even though this explicitly says it should: https://github.blog/2020-01-17-bring-your-monorepo-down-to-size-with-sparse-checkout/#sparse-checkout-and-partial-clones With disclaimer:

Keep an eye out for the partial clone feature to become generally available[1].

[1]: GitHub is still evaluating this feature internally while it’s enabled on a select few repositories (including the example used in this post). As the feature stabilizes and matures, we’ll keep you updated with its progress.

So yeah, it's just too hard to be certain at the moment, thanks in part to the joys of GitHub being closed source. But let's keep an eye on it.

Command breakdown

The server should be configured with:

git config --local uploadpack.allowfilter 1
git config --local uploadpack.allowanysha1inwant 1

Command breakdown:

• --filter=blob:none skips all blobs, but still fetches all tree objects

• --filter=tree:0 skips the unneeded trees: https://www.spinics.net/lists/git/msg342006.html

• --depth 1 already implies --single-branch, see also: How do I clone a single branch in Git?

• file://$(path) is required to overcome git clone protocol shenanigans: How to shallow clone a local git repository with a relative path?

• --filter=combine:FILTER1+FILTER2 is the syntax to use multiple filters at once, trying to pass --filter for some reason fails with: "multiple filter-specs cannot be combined". This was added in Git 2.24 at e987df5fe62b8b29be4cdcdeb3704681ada2b29e "list-objects-filter: implement composite filters"

  Edit: on Git 2.28, I experimentally see that --filter=FILTER1 --filter FILTER2 also has the same effect, since GitHub does not implement combine: yet as of 2020-09-18 and complains fatal: invalid filter-spec 'combine:blob:none+tree:0'. TODO introduced in which version?

The format of --filter is documented on man git-rev-list.

Docs on Git tree:

• https://github.com/git/git/blob/v2.19.0/Documentation/technical/partial-clone.txt
• https://github.com/git/git/blob/v2.19.0/Documentation/rev-list-options.txt#L720

Conclusions: all blobs from outside of d1/ are missing. E.g. 0975df9b39e23c15f63db194df7f45c76528bccb, which is d2/b is not there after checking out d1/a.

Note that root/root and mybranch/mybranch are also missing, but --depth 1 hides that from the list of missing files. If you remove --depth 1, then they show on the list of missing files.

I have a dream

This feature could revolutionize Git.

Imagine having all the code base of your enterprise in a single repo without ugly third-party tools like repo.

Imagine storing huge blobs directly in the repo without any ugly third party extensions.

Imagine if GitHub would allow per file / directory metadata like stars and permissions, so you can store all your personal stuff under a single repo.

Imagine if submodules were treated exactly like regular directories: just request a tree SHA, and a DNS-like mechanism resolves your request, first looking on your local ~/.git, then first to closer servers (your enterprise's mirror / cache) and ending up on GitHub.

The Eclipse SDK contains a class SocketUtil, that does what you want. You may have a look into the git source code.

When I inspected the problem, I have noticed that the following dll were missing in the output folder. The simple solution is copy Entityframework.dll and Entityframework.sqlserver.dll with the app.config to the output folder if the application is on debug mode. At the same time change, the build option parameter "Copy to output folder" of app.config to copy always. This will solve your problem.

Here is another working example (@angular/cli 1.0.4):

proxy.conf.json :

{
  "/api/*" : {
    "target": "http://localhost:8181",
    "secure": false,
    "logLevel": "debug"
  },
  "/login.html" : {
    "target": "http://localhost:8181/login.html",
    "secure": false,
    "logLevel": "debug"
  }
}

run with :

ng serve --proxy-config proxy.conf.json

In C++17 this is called structured bindings, which allows for the following:

std::map< foo, bar > testing = { /*...blah...*/ };
for ( const auto& [ k, v ] : testing )
{
  std::cout << k << "=" << v << "\n";
}

Think this is, what you are searching for: Allow access to specific projects for Users

Short description without screenshots:
Use Jenkins "Project-based Matrix Authorization Strategy" under "Manage Jenkins" => "Configure System". On the configuration page of each project, you now have "Enable project-based security". Now add each user you want to authorize.

You can resize and then use imagejpeg()

Don't pass 100 as the quality for imagejpeg() - anything over 90 is generally overkill and just gets you a bigger JPEG. For a thumbnail, try 75 and work downwards until the quality/size tradeoff is acceptable.

imagejpeg($tn, $save, 75);

System.Single / float - 7 digits
System.Double / double - 15-16 digits
System.Decimal / decimal - 28-29 significant digits

The way I've been stung by using the wrong type (a good few years ago) is with large amounts:

• £520,532.52 - 8 digits
• £1,323,523.12 - 9 digits

You run out at 1 million for a float.

A 15 digit monetary value:

• £1,234,567,890,123.45

9 trillion with a double. But with division and comparisons it's more complicated (I'm definitely no expert in floating point and irrational numbers - see Marc's point). Mixing decimals and doubles causes issues:

A mathematical or comparison operation that uses a floating-point number might not yield the same result if a decimal number is used because the floating-point number might not exactly approximate the decimal number.

When should I use double instead of decimal? has some similar and more in depth answers.

Using double instead of decimal for monetary applications is a micro-optimization - that's the simplest way I look at it.

Unfortunately, strptime() can only handle the timezone configured by your OS, and then only as a time offset, really. From the documentation:

Support for the %Z directive is based on the values contained in tzname and whether daylight is true. Because of this, it is platform-specific except for recognizing UTC and GMT which are always known (and are considered to be non-daylight savings timezones).

strftime() doesn't officially support %z.

You are stuck with python-dateutil to support timezone parsing, I am afraid.

This probably isn't the most elegant way to do it, but it gets the job done.

Well, as it was said before, you can't GROUP by literals, I think that you are confused cause you can ORDER by 1, 2, 3. When you use functions as your columns, you need to GROUP by the same expression. Besides, the HAVING clause is wrong, you can only use what is in the agreggations. In this case, your query should be like this:

SELECT 
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound,
MAX(qvalues.rid) MaxRid
FROM batchinfo join qvalues 
ON batchinfo.rowid=qvalues.rowid
WHERE LEN(datapath)>4
GROUP BY 
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,

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

Here's what I've been doing to cope with the situation.

I use global imports on a new test class.

import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import static org.mockito.Matchers.*;

When you are finished writing your test and need to commit, you just CTRL+SHIFT+O to organize the packages. For example, you may just be left with:

import static org.mockito.Mockito.doThrow;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Matchers.anyString;

This allows you to code away without getting 'stuck' trying to find the correct package to import.

=, the indent command can take motions. So, gg to get the start of the file, = to indent, G to the end of the file, gg=G.

Your datatype for @location nchar(20) should be @location nvarchar(20), since nChar has a fixed length (filled with Spaces).
If Location is nchar too you will have to convert it:

 ... Cast(Location as nVarchar(200)) like '%'+@location+'%' ...   

To enable nullable parameters with and AND condition just use IsNull or Coalesce for comparison, which is not needed in your example using OR.

e.g. if you would like to compare for Location AND Date and Time.

@location nchar(20),
@time time,
@date date
as
select DonationsTruck.VechileId, Phone, Location, [Date], [Time]
from Vechile, DonationsTruck
where Vechile.VechileId = DonationsTruck.VechileId
and (((Location like '%'+IsNull(@location,Location)+'%')) and [Date]=IsNUll(@date,date) and [Time] = IsNull(@time,Time))

In my case, I needed to install a plugin to an offline build server that's running a Windows Server (version won't matter here). I already installed Jenkins on my laptop to test out changes in advance and it is running on localhost:8080 as a windows service.

So if you are willing to take the time to setup Jenkins on a machine with Internet connection and carry these changes to the offline server Jenkins (it works, confirmed by me!), these are steps you could follow:

• Jenkins on my laptop: Open up Jenkins, http://localhost:8080
• Navigator: Manage Jenkins | Download plugin without install option
• Windows Explorer: Copy the downloaded plugin file that is located at "c:\program files (x86)\Jenkins\plugins" folder (i.e. role-strategy.jpi)
• Paste it into a shared folder in the offline server
• Stop the Jenkins Service (Offline Server Jenkins) through Component Services, Jenkins Service
• Copy the plugin file (i.e. role-strategy.jpi) into "c:\program files (x86)\Jenkins\plugins" folder on the (Offline Jenkins) server
• Restart Jenkins and voila! It should be installed.

Here is an example to config HTTP and HTTPS in same config block with ipv6 support. The config is tested in Ubuntu Server and NGINX/1.4.6 but this should work with all servers.

server {
    # support http and ipv6
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    # support https and ipv6
    listen 443 default_server ssl;
    listen [::]:443 ipv6only=on default_server ssl;

    # path to web directory
    root /path/to/example.com;
    index index.html index.htm;

    # domain or subdomain
    server_name example.com www.example.com;

    # ssl certificate
    ssl_certificate /path/to/certs/example_com-bundle.crt;
    ssl_certificate_key /path/to/certs/example_com.key;

    ssl_session_timeout 5m;

    ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers "HIGH:!aNULL:!MD5 or HIGH:!aNULL:!MD5:!3DES";
    ssl_prefer_server_ciphers on;
}

Don't include ssl on which may cause 400 error. The config above should work for

http://example.com

http://www.example.com

https://example.com

https://www.example.com

Hope this helps!

(Jun-Nov 2016) The question and its answers are now out-of-date as: 1) GData APIs are the previous generation of Google APIs. While not all GData APIs have been deprecated, all the latest Google APIs do not use the Google Data Protocol; and 2) there is a new Google Sheets API v4 (also not GData).

Moving forward from here, you need to get the Google APIs Client Library for .NET and use the latest Sheets API, which is much more powerful and flexible than any previous API. Here's a C# code sample to help get you started. Also check the .NET reference docs for the Sheets API and the .NET Google APIs Client Library developers guide.

If you're not allergic to Python (if you are, just pretend it's pseudocode ;) ), I made several videos with slightly longer, more "real-world" examples of using the API you can learn from and migrate to C# if desired:

• Migrating SQL data to a Sheet (code deep dive post)
• Formatting text using the Sheets API (code deep dive post)
• Generating slides from spreadsheet data (code deep dive post)
• Those and others in the Sheets API video library

Short Answer

Use <foreach> with a nested <FileSet>

Foreach requires ant-contrib.

Updated Example for recent ant-contrib:

<target name="foo">
  <foreach target="bar" param="theFile">
    <fileset dir="${server.src}" casesensitive="yes">
      <include name="**/*.java"/>
      <exclude name="**/*Test*"/>
    </fileset>
  </foreach>
</target>

<target name="bar">
  <echo message="${theFile}"/>
</target>

This will antcall the target "bar" with the ${theFile} resulting in the current file.

var ans = 334 + '';
var temp = ans.toLowerCase();
alert(temp);

Probably because C's "struct tm" does the same.

Update: Yes, I understand that this answer does not explain the difference between arm64 and armhf. There is a great answer that does explain that on this page. This answer was intended to help set the asker on the right path, as they clearly had a misunderstanding about the capabilities of the Raspberry Pi at the time of asking.

Where are you seeing that the architecture is armhf? On my Raspberry Pi 3, I get:

$ uname -a
armv7l

Anyway, armv7 indicates that the system architecture is 32-bit. The first ARM architecture offering 64-bit support is armv8. See this table for reference.

You are correct that the CPU in the Raspberry Pi 3 is 64-bit, but the Raspbian OS has not yet been updated for a 64-bit device. 32-bit software can run on a 64-bit system (but not vice versa). This is why you're not seeing the architecture reported as 64-bit.

You can follow the GitHub issue for 64-bit support here, if you're interested.

I just had this problem, and the cause seemed to be that a directory had been flagged as in conflict. To fix:

svn update
svn resolved <the directory in conflict>
svn commit

To reset or change the password enter sudo dpkg-reconfigure mysql-server-X.X (X.X is mysql version you have installed i.e. 5.6, 5.7) and then you will prompt a screen where you have to set the new password and then in next step confirm the password and just wait for a moment. That's it.

This match 6 or more any chars but newline:

/^.{6,}$/

As other answers mentioned, (upper case) J and search + replace for \n can be used generally to strip newline characters and to concatenate lines.

But in order to get rid of the trailing newline character in the last line, you need to do this in Vim:

:set noendofline binary
:w

You did not activate the virtual environment before using pip.

Try it with:

$(your venv path) . bin/activate

And then use pip -r requirements.txt on your main folder

This is big endian test from a configure script:

#include <inttypes.h>
int main(int argc, char ** argv){
    volatile uint32_t i=0x01234567;
    // return 0 for big endian, 1 for little endian.
    return (*((uint8_t*)(&i))) == 0x67;
}

There's always the HTML5 download attribute :

This attribute, if present, indicates that the author intends the hyperlink to be used for downloading a resource so that when the user clicks on the link they will be prompted to save it as a local file.

If the attribute has a value, the value will be used as the pre-filled file name in the Save prompt that opens when the user clicks on the link.

var A = [['n','sqrt(n)']];

for(var j=1; j<10; ++j){ 
    A.push([j, Math.sqrt(j)]);
}

var csvRows = [];

for(var i=0, l=A.length; i<l; ++i){
    csvRows.push(A[i].join(','));
}

var csvString = csvRows.join("%0A");
var a         = document.createElement('a');
a.href        = 'data:attachment/csv,' +  encodeURIComponent(csvString);
a.target      = '_blank';
a.download    = 'myFile.csv';

document.body.appendChild(a);
a.click();

Tested in Chrome and Firefox, works fine in the newest versions (as of July 2013).
Works in Opera as well, but does not set the filename (as of July 2013).
Does not seem to work in IE9 (big suprise) (as of July 2013).

An overview over what browsers support the download attribute can be found Here
For non-supporting browsers, one has to set the appropriate headers on the serverside.

Apparently there is a hack for IE10 and IE11, which doesn't support the download attribute (Edge does however).

var A = [['n','sqrt(n)']];

for(var j=1; j<10; ++j){ 
    A.push([j, Math.sqrt(j)]);
}

var csvRows = [];

for(var i=0, l=A.length; i<l; ++i){
    csvRows.push(A[i].join(','));
}

var csvString = csvRows.join("%0A");

if (window.navigator.msSaveOrOpenBlob) {
    var blob = new Blob([csvString]);
    window.navigator.msSaveOrOpenBlob(blob, 'myFile.csv');
} else {
    var a         = document.createElement('a');
    a.href        = 'data:attachment/csv,' +  encodeURIComponent(csvString);
    a.target      = '_blank';

after writing the jquery code perform this validation in your route or in controller.

$.ajax({
url: "/id/edit",
data:
name:name,
method:'get',
success:function(data){
  console.log(data);}
});

Route::get('/', function(){
if(Request::ajax()){
  return 'it's ajax request';}
});

@WilliamJockusch, if I understood correctly your concern, it's not possible (from a mathematical point of view) to always identify an infinite recursion as it would mean to solve the Halting problem. To solve it you'd need a Super-recursive algorithm (like Trial-and-error predicates for example) or a machine that can hypercompute (an example is explained in the following section - available as preview - of this book).

From a practical point of view, you'd have to know:

• How much stack memory you have left at the given time
• How much stack memory your recursive method will need at the given time for the specific output.

Keep in mind that, with the current machines, this data is extremely mutable due to multitasking and I haven't heard of a software that does the task.

Let me know if something is unclear.

More of an alternate solution, but all modern browsers send the domain cookies along with the connection, so using:

var authToken = 'R3YKZFKBVi';

document.cookie = 'X-Authorization=' + authToken + '; path=/';

var ws = new WebSocket(
    'wss://localhost:9000/wss/'
);

End up with the request connection headers:

Cookie: X-Authorization=R3YKZFKBVi

I use the following Ruby script to delete my already merged local and remote branches. If I'm doing it for a repository with multiple remotes and only want to delete from one, I just add a select statement to the remotes list to only get the remotes I want.

#!/usr/bin/env ruby

current_branch = `git symbolic-ref --short HEAD`.chomp
if current_branch != "master"
  if $?.exitstatus == 0
    puts "WARNING: You are on branch #{current_branch}, NOT master."
  else
    puts "WARNING: You are not on a branch"
  end
  puts
end

puts "Fetching merged branches..."
remote_branches= `git branch -r --merged`.
  split("\n").
  map(&:strip).
  reject {|b| b =~ /\/(#{current_branch}|master)/}

local_branches= `git branch --merged`.
  gsub(/^\* /, '').
  split("\n").
  map(&:strip).
  reject {|b| b =~ /(#{current_branch}|master)/}

if remote_branches.empty? && local_branches.empty?
  puts "No existing branches have been merged into #{current_branch}."
else
  puts "This will remove the following branches:"
  puts remote_branches.join("\n")
  puts local_branches.join("\n")
  puts "Proceed?"
  if gets =~ /^y/i
    remote_branches.each do |b|
      remote, branch = b.split(/\//)
      `git push #{remote} :#{branch}`
    end

    # Remove local branches
    `git branch -d #{local_branches.join(' ')}`
  else
    puts "No branches removed."
  end
end

This question might still be visited often enough that it's worth offering an addendum to Mr Kassies' answer. The dict built-in class can be sub-classed so that a default is returned for 'missing' keys. This mechanism works well for pandas. But see below.

In this way it's possible to avoid key errors.

>>> import pandas as pd
>>> data = { 'ID': [ 101, 201, 301, 401 ] }
>>> df = pd.DataFrame(data)
>>> class SurnameMap(dict):
...     def __missing__(self, key):
...         return ''
...     
>>> surnamemap = SurnameMap()
>>> surnamemap[101] = 'Mohanty'
>>> surnamemap[301] = 'Drake'
>>> df['Surname'] = df['ID'].apply(lambda x: surnamemap[x])
>>> df
    ID  Surname
0  101  Mohanty
1  201         
2  301    Drake
3  401         

The same thing can be done more simply in the following way. The use of the 'default' argument for the get method of a dict object makes it unnecessary to subclass a dict.

>>> import pandas as pd
>>> data = { 'ID': [ 101, 201, 301, 401 ] }
>>> df = pd.DataFrame(data)
>>> surnamemap = {}
>>> surnamemap[101] = 'Mohanty'
>>> surnamemap[301] = 'Drake'
>>> df['Surname'] = df['ID'].apply(lambda x: surnamemap.get(x, ''))
>>> df
    ID  Surname
0  101  Mohanty
1  201         
2  301    Drake
3  401         

Downloading file through ajax is always a painful process and In my view it is best to let server and browser do this work of content type negotiation.

I think its best to have

<a href="api/sample/download"></a> 

to do it. This doesn't even require any new windows opening and stuff like that.

The MVC controller as in your sample can be like the one below:

[HttpGet("[action]")]
public async Task<FileContentResult> DownloadFile()
{
    // ...
    return File(dataStream.ToArray(), "text/plain", "myblob.txt");
}

The probable reason why you get this error is likely because you've added the /build folder to your .gitignore file or generally haven't checked it into Git.

So when you Git push Heroku master, the build folder you're referencing don't get pushed to Heroku. And that's why it shows this error.

That's the reason it works properly locally, but not when you deployed to Heroku.

You can use drop command to delete meta data and actual data from HDFS.

And just to delete data and keep the table structure, use truncate command.

You would want to use ->forget()

In SQL you need to use GETDATE():

UPDATE table SET date = GETDATE();

There is no NOW() function.

To answer your question:

In a large table, since the function is evaluated for each row, you will end up getting different values for the updated field.

So, if your requirement is to set it all to the same date I would do something like this (untested):

DECLARE @currDate DATETIME;
SET @currDate = GETDATE();

UPDATE table SET date = @currDate;

I had similar issue. To debug the problem, I've run Wireshark and capture request generated by my code. Then I used XML Spy trial to create a SOAP request (assuming you have WSDL) and compared those two.

This should give you a hint what goes wrong.

You are echoing outside the body tag of your HTML. Put your echos there, and you should be fine.

Also, remove the onclick="alert()" from your submit. This is the cause for your first undefined message.

<?php
  $posted = false;
  if( $_POST ) {
    $posted = true;

    // Database stuff here...
    // $result = mysql_query( ... )
    $result = $_POST['name'] == "danny"; // Dummy result
  }
?>

<html>
  <head></head>
  <body>

  <?php
    if( $posted ) {
      if( $result ) 
        echo "<script type='text/javascript'>alert('submitted successfully!')</script>";
      else
        echo "<script type='text/javascript'>alert('failed!')</script>";
    }
  ?>
    <form action="" method="post">
      Name:<input type="text" id="name" name="name"/>
      <input type="submit" value="submit" name="submit"/>
    </form>
  </body>
</html>

The official docker answer to Run multiple services in a container.

It explains how you can do it with an init system (systemd, sysvinit, upstart) , a script (CMD ./my_wrapper_script.sh) or a supervisor like supervisord.

The && workaround can work only for services that starts in background (daemons) or that will execute quickly without interaction and release the prompt. Doing this with an interactive service (that keeps the prompt) and only the first service will start.

You can use a vector. Instead of worry about different screen sizes you only need to create an .svg file and import it to your project using Vector Asset Studio.

I had success when using driver.close() before driver.quit(). I was previously only using driver.quit().

Could it be a working copy format mismatch? It changed between svn 1.4 and 1.5 and newer tools automatically convert the format, but then the older ones no longer work with the converted copy.

Just use the std:: qualifier in front of string in your header files.

In fact, you should use it for istream and ostream also - and then you will need #include <iostream> at the top of your header file to make it more self contained.

This also should do:

(function() {
    var uniquePrevious = 0;
    uniqueId = function() {
        return uniquePrevious++;
    };
}());

You can also use Guava and do something like this:

// This method returns enum for a given string if it exists, otherwise it returns default enum.
private MyEnum getMyEnum(String enumName) {
  // It is better to return default instance of enum instead of null
  return hasMyEnum(enumName) ? MyEnum.valueOf(enumName) : MyEnum.DEFAULT;
}

// This method checks that enum for a given string exists.
private boolean hasMyEnum(String enumName) {
  return Iterables.any(Arrays.asList(MyEnum.values()), new Predicate<MyEnum>() {
    public boolean apply(MyEnum myEnum) {
      return myEnum.name().equals(enumName);
    }
  }); 
}

In second method I use guava (Google Guava) library which provides very useful Iterables class. Using the Iterables.any() method we can check if a given value exists in a list object. This method needs two parameters: a list and Predicate object. First I used Arrays.asList() method to create a list with all enums. After that I created new Predicate object which is used to check if a given element (enum in our case) satisfies the condition in apply method. If that happens, method Iterables.any() returns true value.

Relative path:

ConnectionString = "Data Source=|DataDirectory|\Database.sdf";

Modifying DataDirectory as executable's path:

string executable = System.Reflection.Assembly.GetExecutingAssembly().Location;
string path = (System.IO.Path.GetDirectoryName(executable));
AppDomain.CurrentDomain.SetData("DataDirectory", path);

This is how to pass the struct by reference. This means that your function can access the struct outside of the function and modify its values. You do this by passing a pointer to the structure to the function.

#include <stdio.h>
/* card structure definition */
struct card
{
    int face; // define pointer face
}; // end structure card

typedef struct card Card ;

/* prototype */
void passByReference(Card *c) ;

int main(void)
{
    Card c ;
    c.face = 1 ;
    Card *cptr = &c ; // pointer to Card c

    printf("The value of c before function passing = %d\n", c.face);
    printf("The value of cptr before function = %d\n",cptr->face);

    passByReference(cptr);

    printf("The value of c after function passing = %d\n", c.face);

    return 0 ; // successfully ran program
}

void passByReference(Card *c)
{
    c->face = 4;
}

This is how you pass the struct by value so that your function receives a copy of the struct and cannot access the exterior structure to modify it. By exterior I mean outside the function.

#include <stdio.h>


/* global card structure definition */
struct card
{
    int face ; // define pointer face
};// end structure card

typedef struct card Card ;

/* function prototypes */
void passByValue(Card c);

int main(void)
{
    Card c ;
    c.face = 1;

    printf("c.face before passByValue() = %d\n", c.face);

    passByValue(c);

    printf("c.face after passByValue() = %d\n",c.face);
    printf("As you can see the value of c did not change\n");
    printf("\nand the Card c inside the function has been destroyed"
        "\n(no longer in memory)");
}


void passByValue(Card c)
{
    c.face = 5;
}

Instead of gdb, run gdbtui. Or run gdb with the -tui switch. Or press C-x C-a after entering gdb. Now you're in GDB's TUI mode.

Enter layout asm to make the upper window display assembly -- this will automatically follow your instruction pointer, although you can also change frames or scroll around while debugging. Press C-x s to enter SingleKey mode, where run continue up down finish etc. are abbreviated to a single key, allowing you to walk through your program very quickly.

If you don't care about the order of the array, then you may want to get the difference between arr1 and arr2 by id using differenceBy() and then simply use concat() to append all the updated objects.

var result = _(arr1).differenceBy(arr2, 'id').concat(arr2).value();

var arr1 = [{_x000D_
  id: '124',_x000D_
  name: 'qqq'_x000D_
}, {_x000D_
  id: '589',_x000D_
  name: 'www'_x000D_
}, {_x000D_
  id: '45',_x000D_
  name: 'eee'_x000D_
}, {_x000D_
  id: '567',_x000D_
  name: 'rrr'_x000D_
}]_x000D_
_x000D_
var arr2 = [{_x000D_
  id: '124',_x000D_
  name: 'ttt'_x000D_
}, {_x000D_
  id: '45',_x000D_
  name: 'yyy'_x000D_
}];_x000D_
_x000D_
var result = _(arr1).differenceBy(arr2, 'id').concat(arr2).value();_x000D_
_x000D_
console.log(result);

Another solution you can use is SQL Developer.

With it, you have the ability to import from a csv file (other delimited files are available).

Just open the table view, then:

• choose actions
• import data
• find your file
• choose your options.

You have the option to have SQL Developer do the inserts for you, create an sql insert script, or create the data for a SQL Loader script (have not tried this option myself).

Of course all that is moot if you can only use the command line, but if you are able to test it with SQL Developer locally, you can always deploy the generated insert scripts (for example).

Just adding another option to the 2 already very good answers.

The context parameter just sets the value of this in the iterator function.

var someOtherArray = ["name","patrick","d","w"];

_.each([1, 2, 3], function(num) { 
    // In here, "this" refers to the same Array as "someOtherArray"

    alert( this[num] ); // num is the value from the array being iterated
                        //    so this[num] gets the item at the "num" index of
                        //    someOtherArray.
}, someOtherArray);

Working Example: http://jsfiddle.net/a6Rx4/

It uses the number from each member of the Array being iterated to get the item at that index of someOtherArray, which is represented by this since we passed it as the context parameter.

If you do not set the context, then this will refer to the window object.

After editing .gitignore to match the ignored files, you can do git ls-files -ci --exclude-standard to see the files that are included in the exclude lists; you can then do

• Linux/MacOS: git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached
• Windows (PowerShell): git ls-files -ci --exclude-standard | % { git rm --cached "$_" }
• Windows (cmd.exe): for /F "tokens=*" %a in ('git ls-files -ci --exclude-standard') do @git rm --cached "%a"

to remove them from the repository (without deleting them from disk).

Edit: You can also add this as an alias in your .gitconfig file so you can run it anytime you like. Just add the following line under the [alias] section (modify as needed for Windows or Mac):

apply-gitignore = !git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached

(The -r flag in xargs prevents git rm from running on an empty result and printing out its usage message, but may only be supported by GNU findutils. Other versions of xargs may or may not have a similar option.)

Now you can just type git apply-gitignore in your repo, and it'll do the work for you!

Tested and works in Safari 5 and IE6+.

Usually (same as I do in mysql/postgres) I stores dates in int(mysql/post) or text(sqlite) to store them in the timestamp format.

Then I will convert them into Date objects and perform actions based on user TimeZone

By far the simplest solution:

if id -u "$user" >/dev/null 2>&1; then
    echo 'user exists'
else
    echo 'user missing'
fi

The >/dev/null 2>&1 can be shortened to &>/dev/null in Bash.

onMouseOver and onMouseLeave with setState at first seemed like a bit of overhead to me - but as this is how react works, it seems the easiest and cleanest solution to me.

rendering a theming css serverside for example, is also a good solution and keeps the react components more clean.

if you dont have to append dynamic styles to elements ( for example for a theming ) you should not use inline styles at all but use css classes instead.

this is a traditional html/css rule to keep html / JSX clean and simple.

I had this due to a simple ordering mistake on my end. I called

[WRONG] docker run <image> <arguments> <command>

When I should have used

docker run <arguments> <image> <command>

Same resolution on similar question: https://stackoverflow.com/a/50762266/6278

str = "aaaaabbbb"
newstr = str[-4:]

See : http://codepad.org/S3zjnKoD

$().ready(function () {

    $.validator.addMethod(
            "tendigits",
            function (value, element) {
                if (value == "")
                    return false;
                return value.match(/^\d{10}$/);
            },
            "Please enter 10 digits Contact # (No spaces or dash)"
            );

    $('#frm_registration').validate({
        rules: {
            phone: "tendigits"
        },
        messages: {
            phone: "Please enter 10 digits Contact # (No spaces or dash)",

        }

    });

})

I would suggest

sapply(foo, typeof)

if you need the actual types of the vectors in the data frame. class() is somewhat of a different beast.

If you don't need to get this information as a vector (i.e. you don't need it to do something else programmatically later), just use str(foo).

In both cases foo would be replaced with the name of your data frame.

For us VBers:

TrimEnd(New Char() {ControlChars.Cr, ControlChars.Lf})

len(nams) should be equal to n in your code. All indexes 0 <= i < n "exist".

Assuming the destination array has enough space, Array.Copy() will work. You might also try using a List<T> and its .AddRange() method.

An alternative is:

for(var word = ''; word.length < 10; word += 'a'){}

If you need to repeat multiple chars, multiply your conditional:

for(var word = ''; word.length < 10 * 3; word += 'foo'){}

NOTE: You do not have to overshoot by 1 as with word = Array(11).join('a')

You cannot and should not rely on the ordering of elements within a JSON object.

From the JSON specification at http://www.json.org/

An object is an unordered set of name/value pairs

As a consequence, JSON libraries are free to rearrange the order of the elements as they see fit. This is not a bug.

You should use hash (#) tables, That you actually looking for because variables value will remain till that execution only. e.g. -

declare @TEMP table (ID int, Name varchar(max))
insert into @temp SELECT ID, Name FROM Table

When above two and below two statements execute separately.

SELECT * FROM @TEMP 
WHERE @TEMP.ID  = 1 

The error will show because the value of variable lost when you execute the batch of query second time. It definitely gives o/p when you run an entire block of code.

The hash table is the best possible option for storing and retrieving the temporary value. It last long till the parent session is alive.

Or you can use the ItemDataBound event in the code behind.

No need to initialize an empty DataFrame (you weren't even doing that, you'd need pd.DataFrame() with the parens).

Instead, to create a DataFrame where each series is a column,

1. make a list of Series, series, and
2. concatenate them horizontally with df = pd.concat(series, axis=1)

Something like:

series = [pd.Series(mat[name][:, 1]) for name in Variables]
df = pd.concat(series, axis=1)

The easiest way I found (and probably the most efficient) is this:

import boto3
from botocore.errorfactory import ClientError

s3 = boto3.client('s3')
try:
    s3.head_object(Bucket='bucket_name', Key='file_path')
except ClientError:
    # Not found
    pass

Another use case is when you want to replace the other branch with yours in a pull request, for example, lets say that you have a software with features A, B, C in develop.

You are developing with the next version and you:

• Removed feature B

• Added feature D

In the process, develop just added hotfixes for feature B.

You can merge develop into next, but that can be messy sometimes, but you can also use git reset --soft origin/develop and create a commit with your changes and the branch is mergeable without conflicts and keep your changes.

It turns out that git reset --soft is a handy command. I personally use it a lot to squash commits that dont have "completed work" like "WIP" so when I open the pull request, all my commits are understandable.

Check this has everything you need

The Chrome team has recently implemented a feature that tells the browser to launch the page fullscreen when the user has added it to the home screen. It is similar to the iOS Safari model.

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

It's a mechanism to invoke an API in an asynchrounous way. The sequence is the following

1. your app invokes the url, passing as parameter the callback url
2. the api respond with a 20x http code (201 I guess, but refer to the api docs)
3. the api works on your request for a certain amount of time
4. the api invokes your app to give you the results, at the callback url address.

So you can invoke the api and tell your user the request is "processing" or "acquired" for example, and then update the status when you receive the response from the api.

Hope it makes sense. -G

Ensure you've the right Eclipse and Server

Ensure that you're using at least Eclipse IDE for Enterprise Java developers (with the Enterprise). It contains development tools to create dynamic web projects and easily integrate servletcontainers (those tools are part of Web Tools Platform, WTP). In case you already had Eclipse IDE for Java (without Enterprise), and manually installed some related plugins, then chances are that it wasn't done properly. You'd best trash it and grab the real Eclipse IDE for Enterprise Java one.

You also need to ensure that you already have a servletcontainer installed on your machine which implements at least the same Servlet API version as the servletcontainer in the production environment, for example Apache Tomcat, Oracle GlassFish, JBoss AS/WildFly, etc. Usually, just downloading the ZIP file and extracting it is sufficient. In case of Tomcat, do not download the EXE format, that's only for Windows based production environments. See also a.o. Several ports (8005, 8080, 8009) required by Tomcat Server at localhost are already in use.

A servletcontainer is a concrete implementation of the Servlet API. Note that the Java EE SDK download at Oracle.com basically contains GlassFish. So if you happen to already have downloaded Java EE SDK, then you basically already have GlassFish. Also note that for example GlassFish and JBoss AS/WildFly are more than just a servletcontainer, they also supports JSF, EJB, JPA and all other Java EE fanciness. See also a.o. What exactly is Java EE?

Integrate Server in Eclipse and associate it with Project

Once having installed both Eclipse for Enterprise Java and a servletcontainer on your machine, do the following steps in Eclipse:

1. Integrate servletcontainer in Eclipse

   a. Via Servers view

   • Open the Servers view in the bottom box.

   • Rightclick there and choose New > Server.

   • Pick the appropriate servletcontainer make and version and walk through the wizard.

     

   b. Or, via Eclipse preferences

   • Open Window > Preferences > Server > Runtime Environments.

   • You can Add, Edit and Remove servers here.

     

2. Associate server with project

   a. In new project

   • Open the Project Navigator/Explorer on the left hand side.

   • Rightclick there and choose New > Project and then in menu Web > Dynamic Web Project.

   • In the wizard, set the Target Runtime to the integrated server.

     

   b. Or, in existing project

   • Rightclick project and choose Properties.

   • In Targeted Runtimes section, select the integrated server.

     

   Either way, Eclipse will then automatically take the servletcontainer's libraries in the build path. This way you'll be able to import and use the Servlet API.

Never carry around loose server-specific JAR files

You should in any case not have the need to fiddle around in the Build Path property of the project. You should above all never manually copy/download/move/include the individual servletcontainer-specific libraries like servlet-api.jar, jsp-api.jar, el-api.jar, j2ee.jar, javaee.jar, etc. It would only lead to future portability, compatibility, classpath and maintainability troubles, because your webapp would not work when it's deployed to a servletcontainer of a different make/version than where those libraries are originally obtained from.

In case you're using Maven, you need to make absolutely sure that servletcontainer-specific libraries which are already provided by the target runtime are marked as <scope>provided</scope>.

Here are some typical exceptions which you can get when you litter the /WEB-INF/lib or even /JRE/lib, /JRE/lib/ext, etc with servletcontainer-specific libraries in a careless attempt to fix the compilation errors:

• java.lang.NullPointerException at org.apache.jsp.index_jsp._jspInit
• java.lang.NoClassDefFoundError: javax/el/ELResolver
• java.lang.NoSuchFieldError: IS_DIR
• java.lang.NoSuchMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext;
• java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;
• org.apache.jasper.JasperException: The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
• java.lang.VerifyError: (class: org/apache/jasper/runtime/JspApplicationContextImpl, method: createELResolver signature: ()Ljavax/el/ELResolver;) Incompatible argument to function
• jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

I'm running under .NET 4.5.2, and I wasn't happy with any of these answers. As I'm talking to a system which supports TLS 1.2, and seeing as SSL3, TLS 1.0, and TLS 1.1 are all broken and unsafe for use, I don't want to enable these protocols. Under .NET 4.5.2, the SSL3 and TLS 1.0 protocols are both enabled by default, which I can see in code by inspecting ServicePointManager.SecurityProtocol. Under .NET 4.7, there's the new SystemDefault protocol mode which explicitly hands over selection of the protocol to the OS, where I believe relying on registry or other system configuration settings would be appropriate. That doesn't seem to be supported under .NET 4.5.2 however. In the interests of writing forwards-compatible code, that will keep making the right decisions even when TLS 1.2 is inevitably broken in the future, or when I upgrade to .NET 4.7+ and hand over more responsibility for selecting an appropriate protocol to the OS, I adopted the following code:

SecurityProtocolType securityProtocols = ServicePointManager.SecurityProtocol;
if (securityProtocols.HasFlag(SecurityProtocolType.Ssl3) || securityProtocols.HasFlag(SecurityProtocolType.Tls) || securityProtocols.HasFlag(SecurityProtocolType.Tls11))
{
    securityProtocols &= ~(SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11);
    if (securityProtocols == 0)
    {
        securityProtocols |= SecurityProtocolType.Tls12;
    }
    ServicePointManager.SecurityProtocol = securityProtocols;
}

This code will detect when a known insecure protocol is enabled, and in this case, we'll remove these insecure protocols. If no other explicit protocols remain, we'll then force enable TLS 1.2, as the only known secure protocol supported by .NET at this point in time. This code is forwards compatible, as it will take into consideration new protocol types it doesn't know about being added in the future, and it will also play nice with the new SystemDefault state in .NET 4.7, meaning I won't have to re-visit this code in the future. I'd strongly recommend adopting an approach like this, rather than hard-coding any particular security protocol states unconditionally, otherwise you'll have to recompile and replace your client with a new version in order to upgrade to a new security protocol when TLS 1.2 is inevitably broken, or more likely you'll have to leave the existing insecure protocols turned on for years on your server, making your organisation a target for attacks.

below solution works for me

1. Delete all .iml files
2. Rebuild project

I know this is a pretty old thread, but to keep things up to date and more relevant, you can use the more accurate performance.now() functionality to get finer grain timing in javascript.

window.performance = window.performance || {};
performance.now = (function() {
    return performance.now       ||
        performance.mozNow    ||
        performance.msNow     ||
        performance.oNow      ||
        performance.webkitNow ||            
        Date.now  /*none found - fallback to browser default */
})();

As stated above, use union tricks.

There are few problems with the ones advised above though, most notably that unaligned memory access is notoriously slow for most architectures, and some compilers won't even recognize such constant predicates at all, unless word aligned.

Because mere endian test is boring, here goes (template) function which will flip the input/output of arbitrary integer according to your spec, regardless of host architecture.

#include <stdint.h>

#define BIG_ENDIAN 1
#define LITTLE_ENDIAN 0

template <typename T>
T endian(T w, uint32_t endian)
{
    // this gets optimized out into if (endian == host_endian) return w;
    union { uint64_t quad; uint32_t islittle; } t;
    t.quad = 1;
    if (t.islittle ^ endian) return w;
    T r = 0;

    // decent compilers will unroll this (gcc)
    // or even convert straight into single bswap (clang)
    for (int i = 0; i < sizeof(r); i++) {
        r <<= 8;
        r |= w & 0xff;
        w >>= 8;
    }
    return r;
};

Usage:

To convert from given endian to host, use:

host = endian(source, endian_of_source)

To convert from host endian to given endian, use:

output = endian(hostsource, endian_you_want_to_output)

The resulting code is as fast as writing hand assembly on clang, on gcc it's tad slower (unrolled &,<<,>>,| for every byte) but still decent.

You just need to wrap it around a String object like this:

String numberString = String(n);

You can also do:

String stringOne = "Hello String";                     // using a constant String
String stringOne =  String('a');                       // converting a constant char into a String
String stringTwo =  String("This is a string");        // converting a constant string into a String object
String stringOne =  String(stringTwo + " with more");  // concatenating two strings
String stringOne =  String(13);                        // using a constant integer
String stringOne =  String(analogRead(0), DEC);        // using an int and a base
String stringOne =  String(45, HEX);                   // using an int and a base (hexadecimal)
String stringOne =  String(255, BIN);                  // using an int and a base (binary)
String stringOne =  String(millis(), DEC);             // using a long and a base

You can also try to use a Polyfill like Fixed-Sticky. Especially when you are using Bootstrap4 the affix component is no longer included:

Dropped the Affix jQuery plugin. We recommend using a position: sticky polyfill instead.

please modify your router.module.ts as:

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [
        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree',
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        },
        {
           path: '',
           redirectTo: 'two',
           pathMatch: 'full'
        }
    ]
},];

and in your component1.html

<h3>In One</h3>

<nav>
    <a routerLink="/two" class="dash-item">...Go to Two...</a>
    <a routerLink="/two/three" class="dash-item">... Go to THREE...</a>
    <a routerLink="/two/four" class="dash-item">...Go to FOUR...</a>
</nav>

<router-outlet></router-outlet>                   // Successfully loaded component2.html
<router-outlet name="nameThree" ></router-outlet> // Error: Cannot match any routes. URL Segment: 'three'
<router-outlet name="nameFour" ></router-outlet>  // Error: Cannot match any routes. URL Segment: 'three'

I found a different way to handle this error. (the variables is according to the original question)

   JsonNode parsedNodes = mapper.readValue(jsonMessage , JsonNode.class);
        Response response = xmlMapper.enable(ACCEPT_EMPTY_STRING_AS_NULL_OBJECT,ACCEPT_SINGLE_VALUE_AS_ARRAY )

CentOS 7 uses firewalld by default now. But all the answers focus on iptables. So I wanted to add an answer related to firewalld.

Since firewalld is a "wrapper" for iptables, using antonio-fornie's answer still seems to work but I was unable to "save" that new rule. So I wasn't able to connect to my apache server as soon as a restart of the firewall happened. Luckily it is actually much more straightforward to make an equivalent change with firewalld commands. First check if firewalld is running:

firewall-cmd --state

If it is running the response will simply be one line that says "running".

To allow http (port 80) connections temporarily on the public zone:

sudo firewall-cmd --zone=public --add-service=http

The above will not be "saved", next time the firewalld service is restarted it'll go back to default rules. You should use this temporary rule to test and make sure it solves your connection issue before moving on.

To permanently allow http connections on the public zone:

sudo firewall-cmd --zone=public --permanent --add-service=http

If you do the "permanent" command without doing the "temporary" command as well, you'll need to restart firewalld to get your new default rules (this might be different for non CentOS systems):

 sudo systemctl restart firewalld.service

If this hasn't solved your connection issues it may be because your interface isn't in the "public zone". The following link is a great resource for learning about firewalld. It goes over in detail how to check, assign, and configure zones: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-using-firewalld-on-centos-7

• DataFrame.loc() : Select rows by index value
• DataFrame.iloc() : Select rows by rows number

example :

1. Select first 5 rows of a table, df1 is your dataframe

df1.iloc[:5]

2. Select first A, B rows of a table, df1 is your dataframe

df1.loc['A','B']

The return type of Html.RenderAction is void that means it directly renders the responses in View where the return type of Html.Action is MvcHtmlString You can catch its render view in controller and modify it by using following method

protected string RenderPartialViewToString(string viewName, object model)
    {
        if (string.IsNullOrEmpty(viewName))
            viewName = ControllerContext.RouteData.GetRequiredString("action");

        ViewData.Model = model;

        using (StringWriter sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
            ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
            viewResult.View.Render(viewContext, sw);
            return sw.GetStringBuilder().ToString();
        }
    }

This will return the Html string of the View.

This is also applicable to Html.Partial and Html.RenderPartial

If you are doing a loading screen, just set the parameter to not keep it in activity stack. In your manifest.xml, where you define your activity do:

<activity android:name=".LoadingScreen" android:noHistory="true" ... />

And in your code there is no need to call .finish() anymore. Just do startActivity(i);

There is also no need to keep a instance of your current activity in a separate field. You can always access it like LoadingScreen.this.doSomething() instead of private LoadingScreen loadingScreen;

<input type="checkbox" checked="checked" onclick="this.checked=true" />

I started from the problem: "how to POST/Submit an Input Checkbox that is disabled?" and in my answer I skipped the comment: "If we want to disable a checkbox we surely need to keep a prefixed value (checked or unchecked) and also we want that the user be aware of it (otherwise we should use a hidden type and not a checkbox)". In my answer I supposed that we want to keep always a checkbox checked and that code works in this way. If we click on that ckeckbox it will be forever checked and its value will be POSTED/Submitted! In the same way if I write onclick="this.checked=false" without checked="checked" (note: default is unchecked) it will be forever unchecked and its value will be not POSTED/Submitted!.

If you set position to other value than static but your element's z-index still doesn't seem to work, it may be that some parent element has z-index set.

The stacking contexts have hierarchy, and each stacking context is considered in the stacking order of the parent's stacking context.

So with following html

div { border: 2px solid #000; width: 100px; height: 30px; margin: 10px; position: relative; background-color: #FFF; }_x000D_
#el3 { background-color: #F0F; width: 100px; height: 60px; top: -50px; }

<div id="el1" style="z-index: 5"></div>_x000D_
<div id="el2" style="z-index: 3">_x000D_
  <div id="el3" style="z-index: 8"></div>_x000D_
</div>

no matter how big the z-index of el3 will be set, it will always be under el1 because it's parent has lower stacking context. You can imagine stacking order as levels where stacking order of el3 is actually 3.8 which is lower than 5.

If you want to check stacking contexts of parent elements, you can use this:

var el = document.getElementById("#yourElement"); // or use $0 in chrome;
do {
    var styles = window.getComputedStyle(el);
    console.log(styles.zIndex, el);
} while(el.parentElement && (el = el.parentElement));

There is a great article about stacking contexts on MDN

What you are saying is in conflict with what it says in the MSDN library at this location:

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractserializer.aspx

I don't see any mention of the SP1 feature you mention.

@Eddie Loeffen's answer seems to be the most popular answer to this question, but it has some bad long term effects. If you review the documentation page for System.Net.ServicePointManager.SecurityProtocol here the remarks section implies that the negotiation phase should just address this (and forcing the protocol is bad practice because in the future, TLS 1.2 will be compromised as well). However, we wouldn't be looking for this answer if it did.

Researching, it appears that the ALPN negotiation protocol is required to get to TLS1.2 in the negotiation phase. We took that as our starting point and tried newer versions of the .Net framework to see where support starts. We found that .Net 4.5.2 does not support negotiation to TLS 1.2, but .Net 4.6 does.

So, even though forcing TLS1.2 will get the job done now, I recommend that you upgrade to .Net 4.6 instead. Since this is a PCI DSS issue for June 2016, the window is short, but the new framework is a better answer.

UPDATE: Working from the comments, I built this:

ServicePointManager.SecurityProtocol = 0;    
foreach (SecurityProtocolType protocol in SecurityProtocolType.GetValues(typeof(SecurityProtocolType)))
    {
        switch (protocol)
        {
            case SecurityProtocolType.Ssl3:
            case SecurityProtocolType.Tls:
            case SecurityProtocolType.Tls11:
                break;
            default:
                ServicePointManager.SecurityProtocol |= protocol;
            break;
        }
    }

In order to validate the concept, I or'd together SSL3 and TLS1.2 and ran the code targeting a server that supports only TLS 1.0 and TLS 1.2 (1.1 is disabled). With the or'd protocols, it seems to connect fine. If I change to SSL3 and TLS 1.1, that failed to connect. My validation uses HttpWebRequest from System.Net and just calls GetResponse(). For instance, I tried this and failed:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls11;
        request.GetResponse();

while this worked:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12;
        request.GetResponse();

This has an advantage over forcing TLS 1.2 in that, if the .Net framework is upgraded so that there are more entries in the Enum, they will be supported by the code as is. It has a disadvantage over just using .Net 4.6 in that 4.6 uses ALPN and should support new protocols if no restriction is specified.

Edit 4/29/2019 - Microsoft published this article last October. It has a pretty good synopsis of their recommendation of how this should be done in the various versions of .net framework.

Try this

Change the order of files it should be like below..

<script src="js/jquery-1.11.0.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/wow.min.js"></script>

Add column "a"

> df["a"] <- 0
> df
  b c d a
1 1 2 3 0
2 1 2 3 0
3 1 2 3 0

Sort by column using colum name

> df <- df[c('a', 'b', 'c', 'd')]
> df
  a b c d
1 0 1 2 3
2 0 1 2 3
3 0 1 2 3

Or sort by column using index

> df <- df[colnames(df)[c(4,1:3)]]
> df
  a b c d
1 0 1 2 3
2 0 1 2 3
3 0 1 2 3

You could use .each() with .children() and a selector within the parenthesis:

//Grab Each Instance of Box.
$(".box").each(function(i){

    //For Each Instance, grab a child called .something1. Fade It Out.
    $(this).children(".something1").fadeOut();
});

Optional value allows you to show absence of value. Little bit like NULL in SQL or NSNull in Objective-C. I guess this will be an improvement as you can use this even for "primitive" types.

// Reimplement the Swift standard library's optional type
enum OptionalValue<T> {
    case None
    case Some(T)
}
var possibleInteger: OptionalValue<Int> = .None
possibleInteger = .Some(100)”

You can use str_pad for adding 0's

str_pad($month, 2, '0', STR_PAD_LEFT); 

string str_pad ( string $input , int $pad_length [, string $pad_string = " " [, int $pad_type = STR_PAD_RIGHT ]] )

You can use gridspec and figure:

import numpy as np
import matplotlib.pyplot as plt 
from matplotlib import gridspec

# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# plot it
fig = plt.figure(figsize=(8, 6)) 
gs = gridspec.GridSpec(1, 2, width_ratios=[3, 1]) 
ax0 = plt.subplot(gs[0])
ax0.plot(x, y)
ax1 = plt.subplot(gs[1])
ax1.plot(y, x)

plt.tight_layout()
plt.savefig('grid_figure.pdf')

http://www.postgresql.org/docs/current/static/functions-datetime.html shows operators you can use for working with dates and times (and intervals).

So you want

SELECT "date"
FROM "Table"
WHERE "date" > (CURRENT_DATE - INTERVAL '10 days');

The operators/functions above are documented in detail:

• CURRENT_DATE
• INTERVAL '10 days'

It depends on whether the setting you have chosen is at "User" scope or "Application" scope.

User scope

User scope settings are stored in

C:\Documents and Settings\ username \Local Settings\Application Data\ ApplicationName

You can read/write them at runtime.

For Vista and Windows 7, folder is

C:\Users\ username \AppData\Local\ ApplicationName

or

C:\Users\ username \AppData\Roaming\ ApplicationName

Application scope

Application scope settings are saved in AppName.exe.config and they are readonly at runtime.

Esc, Ctrl-A, Shift-Enter.

When I installed: ENU\x64\SQLManagementStudio_x64_ENU.exe

I had to choose the following options to get the management Tools:

1. "New SQL Server stand-alone installation or add features to an existing installation."
2. "Add features to an existing instance of SQL Server 2012"
3. Accept the license.
4. Check the box for "Management Tools - Basic".
5. Wait a long time as it installs.

When I was done I had an option "SQL Server Management Studio" within my Start Menu.

Searching for "Management" pulled it up faster within the Start Menu.

In Java, the equals() method that is inherited from Object is:

public boolean equals(Object other);

In other words, the parameter must be of type Object. This is called overriding; your method public boolean equals(Book other) does what is called overloading to the equals() method.

The ArrayList uses overridden equals() methods to compare contents (e.g. for its contains() and equals() methods), not overloaded ones. In most of your code, calling the one that didn't properly override Object's equals was fine, but not compatible with ArrayList.

So, not overriding the method correctly can cause problems.

I override equals the following everytime:

@Override
public boolean equals(Object other){
    if (other == null) return false;
    if (other == this) return true;
    if (!(other instanceof MyClass)) return false;
    MyClass otherMyClass = (MyClass)other;
    ...test other properties here...
}

The use of the @Override annotation can help a ton with silly mistakes.

Use it whenever you think you are overriding a super class' or interface's method. That way, if you do it the wrong way, you will get a compile error.

In a general way, if you want to pick up the first N rows from the J column from pandas dataframe the best way to do this is:

data = dataframe[0:N][:,J]

ISSUE 1:

Started by user anonymous

That does not mean that Jenkins started as an anonymous user.

It just means that the person who started the build was not logged in. If you enable Jenkins security, you can create usernames for people and when they log in, the

"Started by anonymous" 

will change to

"Started by < username >". 

Note: You do not have to enable security in order to run jenkins or to clone correctly.

If you want to enable security and create users, you should see the options at Manage Jenkins > Configure System.

ISSUE 2:

The "can't clone" error is a different issue altogether. It has nothing to do with you logging in to jenkins or enabling security. It just means that Jenkins does not have the credentials to clone from your git SCM.

Check out the Jenkins Git Plugin to see how to set up Jenkins to work with your git repository.

Hope that helps.

When the Resolve Conflicts->Content Menu are disabled, one may be on the Pending files list. We need to select the Conflicted files option from the drop down (top)

This should do the trick as well:

find . -type f -print -exec cat {} \;

Means:

find    = linux `find` command finds filenames, see `man find` for more info
.       = in current directory
-type f = only files, not directories
-print  = show found file
-exec   = additionally execute another linux command
cat     = linux `cat` command, see `man cat`, displays file contents
{}      = placeholder for the currently found filename
\;      = tell `find` command that it ends now here

You further can combine searches trough boolean operators like -and or -or. find -ls is nice, too.

Make sure your refs for pushing are correct. This tutorial is pretty great, right from the documentation:

http://wiki.eclipse.org/EGit/User_Guide#GitHub_Tutorial

You can clone directly from GitHub, you choose where you clone that repository. And when you import that repository to Eclipse, you choose what refspec to push into upstream.

Click on the Git Repository workspace view, and make sure your remote refs are valid. Make sure you are pointing to the right local branch and pushing to the correct remote branch.

I'm currently writing an Objective-C++ framework called Objective-X, wich makes PURE C++ iPHONE PROGRAMMING possible. You can do like this:

#import "ObjectiveX.h"

void GUIApplicationMain() {    
    GUIAlert Alert;
    GUILabel Label;
    GUIScreen MainScreen;

    Alert.set_text(@"Just a lovely alert box!");
    Alert.set_title(@"Hello!");
    Alert.set_button(@"Okay");
    Alert.show();

    Label.set_text(@"Ciao!");
    Label.set_position(100, 200, 120, 40);

    MainScreen.init();
    MainScreen.addGUIControl(Label.init());    
}

and compile it using GCC's appropriate commandline options. I've already compiled this helloworld app&it w0rkX0rz like a charm. ;-) It'll available soon on GoogleCode. Search for Objective-X or visit http://infotronix.orgfree.com/objectivex approx. a week later!

It can easily be done if u had declared a class that extends from Application

This class will be like a singleton, so when u need a context u can get it just like this:

I think this is the better answer and the cleaner

Here is my code from Utilities package:

 public static String getAppNAme(){
     return MyOwnApplication.getInstance().getString(R.string.app_name);
 }

New Note: You probably don't want or need to do this. What you probably want to do is just put those types of command dependencies for build/test etc. in the devDependencies section of your package.json. Anytime you use something from scripts in package.json your devDependencies commands (in node_modules/.bin) act as if they are in your path.

For example:

npm i --save-dev mocha # Install test runner locally
npm i --save-dev babel # Install current babel locally

Then in package.json:

// devDependencies has mocha and babel now

"scripts": {
  "test": "mocha",
  "build": "babel -d lib src",
  "prepublish": "babel -d lib src"
}

Then at your command prompt you can run:

npm run build # finds babel
npm test # finds mocha

npm publish # will run babel first

But if you really want to install globally, you can add a preinstall in the scripts section of the package.json:

"scripts": {
  "preinstall": "npm i -g themodule"
}

So actually my npm install executes npm install again .. which is weird but seems to work.

Note: you might have issues if you are using the most common setup for npm where global Node package installs required sudo. One option is to change your npm configuration so this isn't necessary:

npm config set prefix ~/npm, add $HOME/npm/bin to $PATH by appending export PATH=$HOME/npm/bin:$PATH to your ~/.bashrc.

Here is a way to get a string variable without having to worry about the coding.

To check if element is visible we need to use element.isDisplayed(); But if we need to check for presence of element anywhere in Dom we can use following method

public boolean isElementPresentCheckUsingJavaScriptExecutor(WebElement element) {
        JavascriptExecutor jse=(JavascriptExecutor) driver;
        try {
            Object obj = jse.execute("return typeof(arguments[0]) != 'undefined' && arguments[0] != null;",
                    element);
            if (obj.toString().contains("true")) {
                System.out.println("isElementPresentCheckUsingJavaScriptExecutor: SUCCESS");
                return true;
            } else {
                System.out.println("isElementPresentCheckUsingJavaScriptExecutor: FAIL");
            }

        } catch (NoSuchElementException e) {
            System.out.println("isElementPresentCheckUsingJavaScriptExecutor: FAIL");
        }
        return false;
    }

I made some big lists. One is a list and one is a numpy array.

import numpy as np
import random
arrayv=np.random.randint(0,10,(100000000,1))
listv=[]
for i in range(0,100000000):
    listv.append(random.randint(0,9))

Using jupyter notebook's %%time function I can compare the speed of various things.

2 seconds:

%%time
listv.index(max(listv))

54.6 seconds:

%%time
listv.index(max(arrayv))

6.71 seconds:

%%time
np.argmax(listv)

103 ms:

%%time
np.argmax(arrayv)

numpy's arrays are crazy fast.

A tag is used to mark a version, more specifically it references a point in time on a branch. A branch is typically used to add features to a project.

Since all of the solutions to date used fluent syntax, here is a solution in query expression syntax, for those interested:

var peopleDifference = 
  from person2 in peopleList2
  where !(
      from person1 in peopleList1 
      select person1.ID
    ).Contains(person2.ID)
  select person2;

I think it is different enough from the answers given to be of interest to some, even thought it most likely would be suboptimal for Lists. Now for tables with indexed IDs, this would definitely be the way to go.

ul li:before {
    content: "";
    margin-left: "your negative value";
}

This might be a simple solution to achieve this:

INSERT INTO funds (ID, date, price)
SELECT 23, DATE('2013-02-12'), 22.5
  FROM dual
 WHERE NOT EXISTS (SELECT 1 
                     FROM funds 
                    WHERE ID = 23
                      AND date = DATE('2013-02-12'));

p.s. alternatively (if ID a primary key):

 INSERT INTO funds (ID, date, price)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE ID = 23; -- or whatever you need

Run this convenient SQL query to see running MySQL queries. It can be run from any environment you like, whenever you like, without any code changes or overheads. It may require some MySQL permissions configuration, but for me it just runs without any special setup.

The only catch is that you often miss queries which execute very quickly, so it is most useful for longer-running queries or when the MySQL server has queries which are backing up - in my experience this is exactly the time when I want to view "live" queries.

You can also add conditions to make it more specific just any SQL query.

e.g. Shows all queries running for 5 seconds or more:

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE COMMAND != 'Sleep' AND TIME >= 5;

e.g. Show all running UPDATEs:

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE COMMAND != 'Sleep' AND INFO LIKE '%UPDATE %';

Ok here is my two cents.

If you are planning to seriously get into the game industry I recommend you learn both languages. Starting off with C++ then moving into a managed language like C#. C++ has it's advantages over C#, but C# also has advantages over C++.

Personally I prefer C# over C++ any day. This is because many reasons:, just a few:

1. C# makes programming fun again ;).
2. It's managed code helps me complete complex tasks easily and not forget safety.
3. C#s' is pure OOP, forcing rules in your code that helps keep your code more readable, 'maintainable' and execution is more stable. Productivity rate surpasses C++ by at least 10%, the best C++ programmer could be an even better C# programmer.
4. This isn't really a reason, more like something 'I' like about C#: LINQ.

Now...there are many things that I miss about C++. I miss being able to (completely) manage my own memory. I can't tell you how many times I caught myself trying to 'delete' an instance/reference. Another thing I dislike about C# is the inability to use multiple-inheritance, but then again it has forced me to think more about how to structure my code.

There has been more discussions on this topic than there are stars in the known universe and they all close at a dead end. Neither language is better than the other and refusing either one for the other will just hurt you in the long run. Times change and so do the standards for computer programming.

Whatever language you choose to keep at the top of your list, always keep your options open and don't set your mind to any one single language. You say you already know C++, why not learn C#, it can't hurt and I 'promise' you, it will make you a better C++ programmer.

words = file("test.txt", "r").read().split() #read the words into a list.
uniqWords = sorted(set(words)) #remove duplicate words and sort
for word in uniqWords:
    print words.count(word), word

Normally, you'd get an RST if you do a close which doesn't linger (i.e. in which data can be discarded by the stack if it hasn't been sent and ACK'd) and a normal FIN if you allow the close to linger (i.e. the close waits for the data in transit to be ACK'd).

Perhaps all you need to do is set your socket to linger so that you remove the race condition between a non lingering close done on the socket and the ACKs arriving?

You could transform this dict a little to ensure that (as dicts aren't kept sorted internally), e.g.

pprint([(key, mydict[key]) for key in sorted(mydict.keys())])

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

Here is another way you can change the selected option of a <select> element in javascript. You can use

document.getElementById('salesperson').selectedIndex=1;

Setting it to 1 will make the second element of the dropdown selected. The select element index start from 0.

Here is a sample code. Check if you can use this type of approach:

<html>
<head>
<script language="javascript">

function changeSelected() { 
document.getElementById('salesperson').selectedIndex=1;

} 

</script>
</head>
<body>
<form name="f1">

<select id="salesperson" > 
   <option value"">james</option>
   <option value"">john</option>  
</select> 
<input type="button" value="Change Selected" onClick="changeSelected();">

</form>
</body>
</html>

@Alwin Doss You should provide the -L option before -l. You would have done the other way round probably. Try this :)

A similar option to what was posted above by janderson would be so simply use the .GetAttribute method in selenium 2. Using this, you can grab any item that has a specific value or label that you are looking for. This can be used to determine if an element has a label, style, value, etc. A common way to do this is to loop through the items in the drop down until you find the one that you want and select it. In C#

int items = driver.FindElement(By.XPath("//path_to_drop_Down")).Count(); 
for(int i = 1; i <= items; i++)
{
    string value = driver.FindElement(By.XPath("//path_to_drop_Down/option["+i+"]")).GetAttribute("Value1");
    if(value.Conatains("Label_I_am_Looking_for"))
    {
        driver.FindElement(By.XPath("//path_to_drop_Down/option["+i+"]")).Click(); 
        //Clicked on the index of the that has your label / value
    }
}

Instead of using pull-right class, it is better to use text-right class in the column, because pull-right creates problems sometimes while resizing the page.

Here you go:

div{
    display: none;
}

document.querySelector("button").addEventListener("click", function(){
    document.querySelector("div").style.display = "block";
});

<div>blah blah blah</div>
<button>Show</button>

If you are using Android then you can use android.util.Base64 class.

Encode:

passwd = Base64.encodeToString( passwd.getBytes(), Base64.DEFAULT );

Decode:

passwd = new String( Base64.decode( passwd, Base64.DEFAULT ) );

A simple and fast single line solution.

The Python time.strftime docs say:

When used with the strptime() function, the %p directive only affects the output hour field if the %I directive is used to parse the hour.

Sure enough, changing your %H to %I makes it work.

I have shamelessly pulled some pretty big datasets in memory, and altough it did get sluggish it took maybe 15 Mo of data upwards with pretty intense calculations on the dataset. I doubt you will run into problems with memory unless you have intense calculations on the data and many many rows. Profiling and benchmarking with different mock resultsets will be your best bet to evaluate performance.

Had such a problem when executing forking in php for command line. In my case from time to time the php killed the child process. To fix this, just wait for the process to complete using the command pcntl_wait($status);

here's a piece of code for a visual example:

    #!/bin/php -n
    <?php
    error_reporting(E_ALL & ~E_NOTICE);
    ini_set("log_errors", 1);
    ini_set('error_log', '/media/logs/php/fork.log');
    $ski = substr(str_shuffle(str_repeat("0123456789abcdefghijklmnopqrstuvwxyz", 5)), 0, 5);
    error_log(getmypid().' '.$ski.' start my php');

    $pid = pcntl_fork();
    if($pid) {
    error_log(getmypid().' '.$ski.' start 2');
    // Wait for children to return. Otherwise they 
    // would turn into "Zombie" processes
    // !!!!!! add this !!!!!!
    pcntl_wait($status);
    // !!!!!! add this !!!!!!
    } else {
    error_log(getmypid().' '.$ski.' start 3');
    //[03-Apr-2020 12:13:47 UTC] PHP Warning:  Error while sending QUERY packet. PID=18048 in /speed/sport/fortest.php on line 22457
    mysqli_query($con,$query,MYSQLI_ASYNC);
error_log(getmypid().' '.$ski.' sleep child');
  sleep(15);
    exit;
    } 

   error_log(getmypid().' '.$ski.'end my php');
    exit(0);
    ?>

ShieldUI's export to excel functionality should already support all special chars.

I guess you mean this:

class Value:
    def __init__(self, v=None):
        self.v = v

v1 = Value(1)
v2 = Value(2)

d = {'a': v1, 'b': v1, 'c': v2, 'd': v2}
d['a'].v += 1

d['b'].v == 2 # True

• Python's strings and numbers are immutable objects,
• So, if you want d['a'] and d['b'] to point to the same value that "updates" as it changes, make the value refer to a mutable object (user-defined class like above, or a dict, list, set).
• Then, when you modify the object at d['a'], d['b'] changes at same time because they both point to same object.

You can use .map().

Pass each element in the current matched set through a function, producing a new jQuery object containing the return value.

As the return value is a jQuery object, which contains an array, it's very common to call .get() on the result to work with a basic array.

Use

var arr = $('input[name="pname[]"]').map(function () {
    return this.value; // $(this).val()
}).get();

Sometimes it's knowing what to ask. I didn't know as I am a developer who has taken on some DevOps work.

Apparently 'passwordless' or NOPASSWD login is a thing which you need to put in the /etc/sudoers file.

The answer to my question is at Ansible: best practice for maintaining list of sudoers.

The Ansible playbook code fragment looks like this from my problem:

- name: Make sure we have a 'wheel' group
  group:
    name: wheel
    state: present

- name: Allow 'wheel' group to have passwordless sudo
  lineinfile:
    dest: /etc/sudoers
    state: present
    regexp: '^%wheel'
    line: '%wheel ALL=(ALL) NOPASSWD: ALL'
    validate: 'visudo -cf %s'

- name: Add sudoers users to wheel group
  user:
    name=deployer
    groups=wheel
    append=yes
    state=present
    createhome=yes

- name: Set up authorized keys for the deployer user
  authorized_key: user=deployer key="{{item}}"
  with_file:
    - /home/railsdev/.ssh/id_rsa.pub

And the best part is that the solution is idempotent. It doesn't add the line

%wheel ALL=(ALL) NOPASSWD: ALL

to /etc/sudoers when the playbook is run a subsequent time. And yes...I was able to ssh into the server as "deployer" and run sudo commands without having to give a password.

Set the default value for the active argument in the route.

@echo off
echo Press any key to exit . . .

To use shorthand to get the direction:

int direction = column == 0
                ? 0
                : (column == _gridSize - 1 ? 1 : rand.Next(2));

To simplify the code entirely:

if (column == gridSize - 1 || rand.Next(2) == 1)
{
}
else
{
}

See project.properties in android project. In ADT 14, default.properties was renamed to project.properties.

Quote from the changelog:

default.properties which is the main project’s properties file containing information such as the build platform target and the library dependencies has been renamed project.properties.

*Note: Per the above link, if you don't have a default.properties file, likely you should upgrade your tools.

I have observed that -

1. FtpwebRequest is missing.
2. As the target is FTP, so the NetworkCredential required.

I have prepared a method that works like this, you can replace the value of the variable ftpurl with the parameter TargetDestinationPath. I had tested this method on winforms application :

private void UploadProfileImage(string TargetFileName, string TargetDestinationPath, string FiletoUpload)
        {
            //Get the Image Destination path
            string imageName = TargetFileName; //you can comment this
            string imgPath = TargetDestinationPath; 

            string ftpurl = "ftp://downloads.abc.com/downloads.abc.com/MobileApps/SystemImages/ProfileImages/" + imgPath;
            string ftpusername = krayknot_DAL.clsGlobal.FTPUsername;
            string ftppassword = krayknot_DAL.clsGlobal.FTPPassword;
            string fileurl = FiletoUpload;

            FtpWebRequest ftpClient = (FtpWebRequest)FtpWebRequest.Create(ftpurl);
            ftpClient.Credentials = new System.Net.NetworkCredential(ftpusername, ftppassword);
            ftpClient.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
            ftpClient.UseBinary = true;
            ftpClient.KeepAlive = true;
            System.IO.FileInfo fi = new System.IO.FileInfo(fileurl);
            ftpClient.ContentLength = fi.Length;
            byte[] buffer = new byte[4097];
            int bytes = 0;
            int total_bytes = (int)fi.Length;
            System.IO.FileStream fs = fi.OpenRead();
            System.IO.Stream rs = ftpClient.GetRequestStream();
            while (total_bytes > 0)
            {
                bytes = fs.Read(buffer, 0, buffer.Length);
                rs.Write(buffer, 0, bytes);
                total_bytes = total_bytes - bytes;
            }
            //fs.Flush();
            fs.Close();
            rs.Close();
            FtpWebResponse uploadResponse = (FtpWebResponse)ftpClient.GetResponse();
            string value = uploadResponse.StatusDescription;
            uploadResponse.Close();
        }

The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).

Typical symptoms:

[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100

[root@host /]# netstat -plant | grep 25
tcp        0      0 :::25                       :::*                        LISTEN      1082/exim           

If this happens, make sure that you don't have two entries for localhost in /etc/hosts with different IP addresses, like this (bad) example:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1       localhost localhost.localdomain localhost6 localhost6.localdomain6

To avoid confusion, make sure you only have one entry for localhost, preferably an IPv4 address, like this:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost  localhost.localdomain   localhost4.localdomain4 localhost4
::1       localhost6 localhost6.localdomain6

It works on my case:

import * as JQuery from "jquery";
const $ = JQuery.default;

With the latest .NET Framework, it is possible to return a value from a separate thread using a Task, where the Result property blocks the calling thread until the task finishes:

  Task<MyClass> task = Task<MyClass>.Factory.StartNew(() =>

      string s = "my message";
      double d = 3.14159;
      return new MyClass { Name = s, Number = d };
  });
  MyClass test = task.Result;

Install a JDK.

It's possible to get Eclipse to run with a JRE, or at least it used to be, but why bother? Eclipse is much happier with a JDK.

Remember that the JRE that is used to run Eclipse does not have to be the JRE that Eclipse uses to run an application.

PS. I'm assuming here that the original poster's problem was getting Eclipse to start, and not (as some other Answers seem to address) getting Eclipse to start an application.

The current spec says this regarding flex: 1 1 auto:

Sizes the item based on the width/height properties, but makes them fully flexible, so that they absorb any free space along the main axis. If all items are either flex: auto, flex: initial, or flex: none, any positive free space after the items have been sized will be distributed evenly to the items with flex: auto.

http://www.w3.org/TR/2012/CR-css3-flexbox-20120918/#flex-common

It sounds to me like if you say an element is 100px tall, it is treated more like a "suggested" size, not an absolute. Because it is allowed to shrink and grow, it takes up as much space as its allowed to. That's why adding this line to your "main" element works: height: 0 (or any other smallish number).

As you've noticed, the WHERE clause doesn't allow you to use aggregates in it. That's what the HAVING clause is for.

HAVING t1.field3=MAX(t1.field3)

Objects are instances of classes. Classes are just the blueprints for objects. So given your class definition -

# Note the added (object) - this is the preferred way of creating new classes
class Student(object):
    name = "Unknown name"
    age = 0
    major = "Unknown major"

You can create a make_student function by explicitly assigning the attributes to a new instance of Student -

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    return student

But it probably makes more sense to do this in a constructor (__init__) -

class Student(object):
    def __init__(self, name="Unknown name", age=0, major="Unknown major"):
        self.name = name
        self.age = age
        self.major = major

The constructor is called when you use Student(). It will take the arguments defined in the __init__ method. The constructor signature would now essentially be Student(name, age, major).

If you use that, then a make_student function is trivial (and superfluous) -

def make_student(name, age, major):
    return Student(name, age, major)

For fun, here is an example of how to create a make_student function without defining a class. Please do not try this at home.

def make_student(name, age, major):
    return type('Student', (object,),
                {'name': name, 'age': age, 'major': major})()

From the C++ FQA Lite:

[16.4] Why should I use new instead of trustworthy old malloc()?

FAQ: new/delete call the constructor/destructor; new is type safe, malloc is not; new can be overridden by a class.

FQA: The virtues of new mentioned by the FAQ are not virtues, because constructors, destructors, and operator overloading are garbage (see what happens when you have no garbage collection?), and the type safety issue is really tiny here (normally you have to cast the void* returned by malloc to the right pointer type to assign it to a typed pointer variable, which may be annoying, but far from "unsafe").

Oh, and using trustworthy old malloc makes it possible to use the equally trustworthy & old realloc. Too bad we don't have a shiny new operator renew or something.

Still, new is not bad enough to justify a deviation from the common style used throughout a language, even when the language is C++. In particular, classes with non-trivial constructors will misbehave in fatal ways if you simply malloc the objects. So why not use new throughout the code? People rarely overload operator new, so it probably won't get in your way too much. And if they do overload new, you can always ask them to stop.

Sorry, I just couldn't resist. :)

The middle one writes to the pipeline. Write-Host and Out-Host writes to the console. 'echo' is an alias for Write-Output which writes to the pipeline as well. The best way to write to the console would be using the Write-Host cmdlet.

When an object is written to the pipeline it can be consumed by other commands in the chain. For example:

"hello world" | Do-Something

but this won't work since Write-Host writes to the console, not to the pipeline (Do-Something will not get the string):

Write-Host "hello world" | Do-Something

You can easily list those properties for your device in debug mode using "evaluate expression" dialog using kotlin:

android.os.Build::class.java.fields.map { "Build.${it.name} = ${it.get(it.name)}"}.joinToString("\n")

you can use this approach, pure HTML and CSS no JS needed :)

In C, a string is actually stored as an array of characters, so the 'string pointer' is pointing to the first character. For instance,

char myString[] = "This is some text";

You can access any character as a simple char by using myString as an array, thus:

char myChar = myString[6];
printf("%c\n", myChar); // Prints s

Hope this helps! David

Change the node to and create a file, packages.xsd, in the same folder (and include it in the project) with the following contents:

       //get the main handle and remove it
       //whatever remains is the child pop up window handle

       String mainHandle = driver.getWindowHandle();
       Set<String> allHandles = driver.getWindowHandles();

If you want to convert the HTML special characters and not just remove them as well as strip things down and prepare for plain text this was the solution that worked for me...

function htmlToPlainText($str){
    $str = str_replace(' ', ' ', $str);
    $str = html_entity_decode($str, ENT_QUOTES | ENT_COMPAT , 'UTF-8');
    $str = html_entity_decode($str, ENT_HTML5, 'UTF-8');
    $str = html_entity_decode($str);
    $str = htmlspecialchars_decode($str);
    $str = strip_tags($str);

    return $str;
}

$string = '<p>this is (&nbsp;) a test</p>
<div>Yes this is! &amp; does it get "processed"? </div>'

htmlToPlainText($string);
// "this is ( ) a test. Yes this is! & does it get processed?"`

html_entity_decode w/ ENT_QUOTES | ENT_XML1 converts things like ' htmlspecialchars_decode converts things like & html_entity_decode converts things like '< and strip_tags removes any HTML tags left over.

Batch uses the less than and greater than brackets as input and output pipes.

>file.ext

Using only one output bracket like above will overwrite all the information in that file.

>>file.ext

Using the double right bracket will add the next line to the file.

(
echo
echo
)<file.ext

This will execute the parameters based on the lines of the file. In this case, we are using two lines that will be typed using "echo". The left bracket touching the right parenthesis bracket means that the information from that file will be piped into those lines.

I have compiled an example-only read/write file. Below is the file broken down into sections to explain what each part does.

@echo off
echo TEST R/W
set SRU=0

SRU can be anything in this example. We're actually setting it to prevent a crash if you press Enter too fast.

set /p SRU=Skip Save? (y): 
if %SRU%==y goto read
set input=1
set input2=2
set /p input=INPUT: 
set /p input2=INPUT2: 

Now, we need to write the variables to a file.

(echo %input%)> settings.cdb
(echo %input2%)>> settings.cdb
pause

I use .cdb as a short form for "Command Database". You can use any extension. The next section is to test the code from scratch. We don't want to use the set variables that were run at the beginning of the file, we actually want them to load FROM the settings.cdb we just wrote.

:read
(
set /p input=
set /p input2=
)<settings.cdb

So, we just piped the first two lines of information that you wrote at the beginning of the file (which you have the option to skip setting the lines to check to make sure it's working) to set the variables of input and input2.

echo %input%
echo %input2%
pause
if %input%==1 goto newecho
pause
exit

:newecho
echo If you can see this, good job!
pause
exit

This displays the information that was set while settings.cdb was piped into the parenthesis. As an extra good-job motivator, pressing enter and setting the default values which we set earlier as "1" will return a good job message. Using the bracket pipes goes both ways, and is much easier than setting the "FOR" stuff. :)

This question has been posted long time ago, but I found an alternative way to answer it. So I decided to share it here.
Firstly, one must know that: if two vectors are perpendicular, their dot product equals zero.
The normal vector (x',y') is perpendicular to the line connecting (x1,y1) and (x2,y2). This line has direction (x2-x1,y2-y1), or (dx,dy).
So,

(x',y').(dx,dy) = 0
x'.dx + y'.dy = 0

The are plenty of pairs (x',y') that satisfy the above equation. But the best pair that ALWAYS satisfies is either (dy,-dx) or (-dy,dx)

If you want to use something similar to the JavaScript, you just need to convert to strings first:

Console.WriteLine(mon.ToString() + "." + da.ToString() + "." + yer.ToString());

But a (much) better way would be to use the format option:

Console.WriteLine("{0}.{1}.{2}", mon, da, yer);

Guys regarding time taken for importing huge files most importantly it takes more time is because default setting of mysql is "autocommit = true", you must set that off before importing your file and then check how import works like a gem...

First open MySQL:

mysql -u root -p

Then, You just need to do following :

mysql>use your_db

mysql>SET autocommit=0 ; source the_sql_file.sql ; COMMIT ;

$image_path = "F:\Program Files\SSH Communications Security\SSH Secure Shell\Output.map";
$arr = explode('\\',$image_path);
$name = end($arr);

Here is another way you can get to the root of your website without hard coding the url:

var response = Request.CreateResponse(HttpStatusCode.Moved);
string fullyQualifiedUrl = Request.RequestUri.GetLeftPart(UriPartial.Authority);
response.Headers.Location = new Uri(fullyQualifiedUrl);

Note: Will only work if both your MVC website and WebApi are on the same URL

This is how I solved

   <a href="#" >
      <button type="button" class="btn btn-info">Button Text</button>
   </a>  

Clearly you're passing in d.keys() to your shuffle function. Probably this was written with python2.x (when d.keys() returned a list). With python3.x, d.keys() returns a dict_keys object which behaves a lot more like a set than a list. As such, it can't be indexed.

The solution is to pass list(d.keys()) (or simply list(d)) to shuffle.

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

Here is an answer by way of example:

In order to make sure data loggers are online a cron script runs every 15 minutes that looks like this:

#!/bin/bash
#
if ! ping -c 1 SOLAR &>/dev/null
then
  echo "SUBJECT:  SOLAR is not responding to ping" | ssmtp [email protected]
  echo "SOLAR is not responding to ping" | ssmtp [email protected]
else
  echo "SOLAR is up"
fi
#
if ! ping -c 1 OUTSIDE &>/dev/null
then
  echo "SUBJECT:  OUTSIDE is not responding to ping" | ssmtp [email protected]
  echo "OUTSIDE is not responding to ping" | ssmtp [email protected]
else
  echo "OUTSIDE is up"
fi
#

...and so on for each data logger that you can see in the montage at http://www.SDsolarBlog.com/montage

FYI, using &>/dev/null redirects all output from the command, including errors, to /dev/null

(The conditional only requires the exit status of the ping command)

Also FYI, note that since cron jobs run as root there is no need to use sudo ping in a cron script.

mongo db_name --eval "db.user_info.find().forEach(function(o) {print(o._id);})"

If all you want to do is conditionally show or hide a <div>, then you could declare it as an <asp:panel > (renders to html as a div tag) and set it's .Visible property.

The identity section goes under the system.web section, not under authentication:

<system.web>
  <authentication mode="Windows"/>
  <identity impersonate="true" userName="foo" password="bar"/>
</system.web>

Just an update on more current OS's (Vista, Win7, etc.) - the temp file path has changed may be different based on several variables. The items below are not definitive, however, they are a few I have encountered:

"temp" environment variable setting - then it would be:

%temp%\Temporary ASP.NET Files

Permissions and what application/process (VS, IIS, IIS Express) is running the .Net compiler. Accessing the C:\WINDOWS\Microsoft.NET\Framework folders requires elevated permissions and if you are not developing under an account with sufficient permissions then this folder might be used:

c:\Users\[youruserid]\AppData\Local\Temp\Temporary ASP.NET Files

There are also cases where the temp folder can be set via config for a machine or site specific using this:

<compilation tempDirectory="d:\MyTempPlace" />

I even have a funky setup at work where we don't run Admin by default, plus the IT guys have login scripts that set %temp% and I get temp files in 3 different locations depending on what is compiling things! And I'm still not certain about how these paths get picked....sigh.

Still, dthrasher is correct, you can just delete these and VS and IIS will just recompile them as needed.

I read the following and think it makes sense too:

Taking Care of Business

Remember, one of the most important OO rules is that an object is responsible for itself. This means that issues regarding the life cycle of a class should be handled in the class, not delegated to language constructs like static, and so on.

from the book Objected-Oriented Thought Process 4th Ed.

On this page you can test the performance of each method yourself :)

http://jsperf.com/cast-to-string/2

here, on all machines and browsers, ' "" + str ' is the fastest one, (String)str is the slowest

Here is an answer to your question for you to check.

using System;
using System.Globalization;
using System.Text.RegularExpressions;

public class RegexUtilities
{    
   public bool IsValidEmail(string strIn)
   {
       if (String.IsNullOrEmpty(strIn))
       {
          return false;

       }

       // Use IdnMapping class to convert Unicode domain names.

       try 
       {
          strIn = Regex.Replace(strIn, @"(@)(.+)$", this.DomainMapper, RegexOptions.None, TimeSpan.FromMilliseconds(200));

       }
       catch (RegexMatchTimeoutException) 
       {
           return false;

       }

       if (invalid)
       {
           return false;

       }

       // Return true if strIn is in valid e-mail format.    

       try 
       {
          return Regex.IsMatch(strIn, @"^(?("")("".+?(?<!\\)""@)|(([0-9a-z]((\.(?!\.))|       [-!#\$%&'\*\+/=\?\^`\{\}\|~\w])*)(?<=[0-9a-z])@))(?(\[)(\[(\d{1,3}\.){3}\d{1,3}\])|(([0-9a-z][-\w]*[0-9a-z]*\.)+[a-z0-9][\-a-z0-9]{0,22}[a-z0-9]))$", RegexOptions.IgnoreCase, TimeSpan.FromMilliseconds(250));

       }
       catch (RegexMatchTimeoutException) 
       {
          return false;

       }

   }


   private string DomainMapper(Match match)
   {
      // IdnMapping class with default property values.

      IdnMapping idn = new IdnMapping();

      string domainName = match.Groups[2].Value;

      try 
      {
         domainName = idn.GetAscii(domainName);

      }
      catch (ArgumentException) 
      {
         invalid = true;

      }

      return match.Groups[1].Value + domainName;

   }

}

Fully working solution based on answer by Jan Turon - behaves like getEventListeners() from console:

(There is a little bug with duplicates. It doesn't break much anyway.)

(function() {
  Element.prototype._addEventListener = Element.prototype.addEventListener;
  Element.prototype.addEventListener = function(a,b,c) {
    if(c==undefined)
      c=false;
    this._addEventListener(a,b,c);
    if(!this.eventListenerList)
      this.eventListenerList = {};
    if(!this.eventListenerList[a])
      this.eventListenerList[a] = [];
    //this.removeEventListener(a,b,c); // TODO - handle duplicates..
    this.eventListenerList[a].push({listener:b,useCapture:c});
  };

  Element.prototype.getEventListeners = function(a){
    if(!this.eventListenerList)
      this.eventListenerList = {};
    if(a==undefined)
      return this.eventListenerList;
    return this.eventListenerList[a];
  };
  Element.prototype.clearEventListeners = function(a){
    if(!this.eventListenerList)
      this.eventListenerList = {};
    if(a==undefined){
      for(var x in (this.getEventListeners())) this.clearEventListeners(x);
        return;
    }
    var el = this.getEventListeners(a);
    if(el==undefined)
      return;
    for(var i = el.length - 1; i >= 0; --i) {
      var ev = el[i];
      this.removeEventListener(a, ev.listener, ev.useCapture);
    }
  };

  Element.prototype._removeEventListener = Element.prototype.removeEventListener;
  Element.prototype.removeEventListener = function(a,b,c) {
    if(c==undefined)
      c=false;
    this._removeEventListener(a,b,c);
      if(!this.eventListenerList)
        this.eventListenerList = {};
      if(!this.eventListenerList[a])
        this.eventListenerList[a] = [];

      // Find the event in the list
      for(var i=0;i<this.eventListenerList[a].length;i++){
          if(this.eventListenerList[a][i].listener==b, this.eventListenerList[a][i].useCapture==c){ // Hmm..
              this.eventListenerList[a].splice(i, 1);
              break;
          }
      }
    if(this.eventListenerList[a].length==0)
      delete this.eventListenerList[a];
  };
})();

Usage:

someElement.getEventListeners([name]) - return list of event listeners, if name is set return array of listeners for that event

someElement.clearEventListeners([name]) - remove all event listeners, if name is set only remove listeners for that event

If anyone is interested in a sortable list with a changing index per listitem (1st, 2nd, 3th etc...:

http://jsfiddle.net/aph0c1rL/1/

$(".sortable").sortable(
{
  handle:         '.handle'
, placeholder:    'sort-placeholder'
, forcePlaceholderSize: true
, start: function( e, ui )
{
    ui.item.data( 'start-pos', ui.item.index()+1 );
}
, change: function( e, ui )
  {
      var seq
      , startPos = ui.item.data( 'start-pos' )
      , $index
      , correction
      ;

      // if startPos < placeholder pos, we go from top to bottom
      // else startPos > placeholder pos, we go from bottom to top and we need to correct the index with +1
      //
      correction = startPos <= ui.placeholder.index() ? 0 : 1;

      ui.item.parent().find( 'li.prize').each( function( idx, el )
      {
        var $this = $( el )
        , $index = $this.index()
        ;

        // correction 0 means moving top to bottom, correction 1 means bottom to top
        //
        if ( ( $index+1 >= startPos && correction === 0) || ($index+1 <= startPos && correction === 1 ) )
        {
          $index = $index + correction;
          $this.find( '.ordinal-position').text( $index + ordinalSuffix( $index ) );
        }

      });

      // handle dragged item separatelly
      seq = ui.item.parent().find( 'li.sort-placeholder').index() + correction;
      ui.item.find( '.ordinal-position' ).text( seq + ordinalSuffix( seq ) );
} );

// this function adds the correct ordinal suffix to the provide number
function ordinalSuffix( number )
{
  var suffix = '';

  if ( number / 10 % 10 === 1 )
  {
    suffix = "th";
  }
  else if ( number > 0 )
  {

    switch( number % 10 )
    {
      case 1:
        suffix = "st";
        break;
      case 2:
        suffix = "nd";
        break;
      case 3:
        suffix = "rd";
        break;
      default:
        suffix = "th";
        break;
    }
  }
  return suffix;
}

Your markup can look like this:

<ul class="sortable ">
<li >        
    <div>
        <span class="ordinal-position">1st</span>
         A header

VS2017 supports ssis or ssrs projects if you install SSDT for VS2017 here.

Click on the newly downloaded file and check SSIS or SSRS components that you required, as show in diagram :-

Once you have installed this, try opening ssis / ssrs project. I managed to open ssis developed on vs2010.

You should see these component installed. (reboot if you don't see them).

Try open your project again. If you get 'incompatible project' - right click on your project, select "reload project" (not reopen the solution)

This worked for me:

     info($("#notification"), data);
    },
    beforeSend:function(){
         info($("#notification"),"Deleting "+count+" messages");
    },
    error:function(jqXHR, textStatus, errorMessage){
        error($("#notification"),errorMessage);
    }
});

And this for your PHP:

$messages = $_POST['messages']
foreach($messages as $msg){
    echo $msg;
}

I found a lot of people recommending ddSlick.js it seems to be a really cool option ! unfortunately it doesnt work as expected for me, maybe I didn't know how to integrate it, today I discovered a library like bootstrap named : MaterialiseCss so I returned to this section to help !!

Sometimes if a Thread was started and it loaded a downside dynamic class which is processing with lots of Thread/currentThread sleep while ignoring interrupted Exception catch(es), one interrupt might not be enough to completely exit execution.

In that case, we can supply these loop-based interrupts:

while(th.isAlive()){
    log.trace("Still processing Internally; Sending Interrupt;");
    th.interrupt();
    try {
        Thread.currentThread().sleep(100);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

The :nth-child(n) selector matches every element that is the nth child, regardless of type, of its parent. Odd and even are keywords that can be used to match child elements whose index is odd or even (the index of the first child is 1).

this is what you want:

<html>
    <head>
        <style>
            li { color: blue }<br>
            li:nth-child(even) { color:red }
            li:nth-child(odd) { color:green}
        </style>
    </head>
    <body>
        <ul>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
        </ul>
    </body>
</html>
