I'd use onMouseOver & onMouseOut. Cause in React

The onMouseEnter and onMouseLeave events propagate from the element being left to the one being entered instead of ordinary bubbling and do not have a capture phase.

Here it is in the React documentation for mouse events.

You just try this, Its so easy

 <script>

  $("#YourDropDownId").change(function () {
            alert($("#YourDropDownId").val());
        });

</script>

Just use this css method:

body{
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

You can find the same answer here: How to disable text selection highlighting using CSS?

All you need to do is set the width and height attributes to be the size of the canvas, dynamically. So you use CSS to make it stretch over the entire browser window, then you have a little function in javascript which measures the width and height, and assigns them. I'm not terribly familliar with jQuery, so consider this psuedocode:

window.onload = window.onresize = function() {
  theCanvas.width = theCanvas.offsetWidth;
  theCanvas.height = theCanvas.offsetHeight;
}

The width and height attributes of the element determine how many pixels it uses in it's internal rendering buffer. Changing those to new numbers causes the canvas to reinitialise with a differently sized, blank buffer. Browser will only stretch the graphics if the width and height attributes disagree with the actual real world pixel width and height.

I think the variable name 'self' should not be used this way anymore, since modern browsers provide a global variable self pointing to the global object of either a normal window or a WebWorker.

To avoid confusion and potential conflicts, you can write var thiz = this or var that = this instead.

Capture the onContextMenu event, and return false in the event handler.

You can also capture the click event and check which mouse button fired the event with event.button, in some browsers anyway.

Code I use myself:

std::string prefix = "-param=";
std::string argument = argv[1];
if(argument.substr(0, prefix.size()) == prefix) {
    std::string argumentValue = argument.substr(prefix.size());
}

I use Eclipse Java EE edition

Create a "Dynamic Web Project"

Install a local server in the server view, for the version of Tomcat I'm using. Then debug, and run on that server for testing.

When I deploy I export the project to a war file.

One might also use, works ok in all browsers, require javascript:

onselectstart = (e) => {e.preventDefault()}

Example:

onselectstart = (e) => {_x000D_
  e.preventDefault()_x000D_
  console.log("nope!")_x000D_
  }

Select me!

One other js alternative, by testing CSS supports, and disable userSelect, or MozUserSelect for Firefox.

let FF_x000D_
if (CSS.supports("( -moz-user-select: none )")){FF = 1} else {FF = 0}_x000D_
(FF===1) ? document.body.style.MozUserSelect="none" : document.body.style.userSelect="none"

Select me!

Pure css, same logic. Warning you will have to extend those rules to every browser, this can be verbose.

@supports (user-select:none) {_x000D_
  div {_x000D_
    user-select:none_x000D_
  }_x000D_
}_x000D_
_x000D_
@supports (-moz-user-select:none) {_x000D_
  div {_x000D_
    -moz-user-select:none_x000D_
  }_x000D_
}

<div>Select me!</div>

Assuming you are generating a shared library, most probably what happens is that the variant of liblog4cplus.a you are using wasn't compiled with -fPIC. In linux, you can confirm this by extracting the object files from the static library and checking their relocations:

ar -x liblog4cplus.a  
readelf --relocs fileappender.o | egrep '(GOT|PLT|JU?MP_SLOT)'

If the output is empty, then the static library is not position-independent and cannot be used to generate a shared object.

Since the static library contains object code which was already compiled, providing the -fPIC flag won't help.

You need to get ahold of a version of liblog4cplus.a compiled with -fPIC and use that one instead.

I have had this exact issue for almost 2 weeks, extremely frustrating but I FINALLY found this site and it was a clear walk-through of what to do.

http://blog.summitcloud.com/2010/01/multivalue-parameters-with-stored-procedures-in-ssrs-sql/

I hope this helps people because it was exactly what I was looking for

We can check using ps command

# ps -aux | grep ssh

Will show all shh service running and we can find the tunnel service listed

There is no need to use the Third loop to check the second largest number in the array. You can only use two loops(one for insertion and another is for checking.

Refer this code.

#include <stdio.h>

int main()

{
int a[10], n;

int i;

printf("enter number of elements you want in array");

scanf("%d", &n);

printf("enter elements");

for (i = 0; i < n; i++) {
    scanf("%d", &a[i]);
}

int largest1 = a[0],largest2 = a[0];

for (i = 0; i < n; i++) 
{
    if (a[i] > largest1) 
    {
         largest2=largest1;
         largest1 = a[i];
    }
}

printf("First and second largest number is %d and %d ", largest1, largest2);
}

Hope this code will work for you.

Enjoy Coding :)

Sum of total_vm is 847170 and sum of rss is 214726, these two values are counted in 4kB pages, which means when oom-killer was running, you had used 214726*4kB=858904kB physical memory and swap space.

Since your physical memory is 1GB and ~200MB was used for memory mapping, it's reasonable for invoking oom-killer when 858904kB was used.

rss for process 2603 is 181503, which means 181503*4KB=726012 rss, was equal to sum of anon-rss and file-rss.

[11686.043647] Killed process 2603 (flasherav) total-vm:1498536kB, anon-rss:721784kB, file-rss:4228kB

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

If u need to connect your application to a server you can do it through PHP/MySQL and JSON http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/ .Mysql Connection code should be in AsynTask class. Dont run it in Main Thread.

The simplest solution is probably:

In [10]: ''.join(set('aaabcabccd'))
Out[10]: 'acbd'

Note that this doesn't guarantee the order in which the letters appear in the output, even though the example might suggest otherwise.

You refer to the output as a "list". If a list is what you really want, replace ''.join with list:

In [1]: list(set('aaabcabccd'))
Out[1]: ['a', 'c', 'b', 'd']

As far as performance goes, worrying about it at this stage sounds like premature optimization.

If you want to prevent the user from enter non-numeric values at the time of enter the information in the TextBox, you can use the Event OnKeyPress like this:

private void txtAditionalBatch_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (!char.IsDigit(e.KeyChar)) e.Handled = true;         //Just Digits
            if (e.KeyChar == (char)8) e.Handled = false;            //Allow Backspace
            if (e.KeyChar == (char)13) btnSearch_Click(sender, e);  //Allow Enter            
        }

This solution doesn't work if the user paste the information in the TextBox using the mouse (right click / paste) in that case you should add an extra validation.

Another option is to use TOML, which is an INI-like format created by Tom Preston-Werner. I built a Go parser for it that is extensively tested. You can use it like other options proposed here. For example, if you have this TOML data in something.toml

Age = 198
Cats = [ "Cauchy", "Plato" ]
Pi = 3.14
Perfection = [ 6, 28, 496, 8128 ]
DOB = 1987-07-05T05:45:00Z

Then you can load it into your Go program with something like

type Config struct {
    Age int
    Cats []string
    Pi float64
    Perfection []int
    DOB time.Time
}

var conf Config
if _, err := toml.DecodeFile("something.toml", &conf); err != nil {
    // handle error
}

If you're modifying your class to accept a Stream instead of a filename, don't bother converting to a MemoryStream. Let the underlying Stream handle the operations:

public class MyClass
{ 
    Stream _s;

    public MyClass(Stream s) { _s = s; }
}

But if you really need a MemoryStream for internal operations, you'll have to copy the data out of the source Stream into the MemoryStream:

public MyClass(Stream stream)
{
    _ms = new MemoryStream();
    CopyStream(stream, _ms);
}

// Merged From linked CopyStream below and Jon Skeet's ReadFully example
public static void CopyStream(Stream input, Stream output)
{
    byte[] buffer = new byte[16*1024];
    int read;
    while((read = input.Read (buffer, 0, buffer.Length)) > 0)
    {
        output.Write (buffer, 0, read);
    }
}

anyway it's too late but my solution was simple right-click on error-message in Eclipse and choosing Quick Fix >> Ignore for every pom with such errors

The short version is that you cannot use variable-width patterns in lookbehinds using Python's re module. There is no way to change this:

>>> import re
>>> re.sub("(?<=foo)bar(?=baz)", "quux", "foobarbaz")
'fooquuxbaz'
>>> re.sub("(?<=fo+)bar(?=baz)", "quux", "foobarbaz")

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    re.sub("(?<=fo+)bar(?=baz)", "quux", string)
  File "C:\Development\Python25\lib\re.py", line 150, in sub
    return _compile(pattern, 0).sub(repl, string, count)
  File "C:\Development\Python25\lib\re.py", line 241, in _compile
    raise error, v # invalid expression
error: look-behind requires fixed-width pattern

This means that you'll need to work around it, the simplest solution being very similar to what you're doing now:

>>> re.sub("(fo+)bar(?=baz)", "\\1quux", "foobarbaz")
'fooquuxbaz'
>>>
>>> # If you need to turn this into a callable function:
>>> def replace(start, replace, end, replacement, search):
        return re.sub("(" + re.escape(start) + ")" + re.escape(replace) + "(?=" + re.escape + ")", "\\1" + re.escape(replacement), search)

This doesn't have the elegance of the lookbehind solution, but it's still a very clear, straightforward one-liner. And if you look at what an expert has to say on the matter (he's talking about JavaScript, which lacks lookbehinds entirely, but many of the principles are the same), you'll see that his simplest solution looks a lot like this one.

$('#submenu li').hover(function(){
    $('#carousel').css('backgroundPosition', newValue);
});

These are few things which will help you in understanding everything... using iloc

In iloc, [initial row:ending row, initial column:ending column]

case 1: if you want only last column --- df.iloc[:,-1] & df.iloc[:,-1:] this means that you want only the last column...

case 2: if you want all columns and all rows except the last column --- df.iloc[:,:-1] this means that you want all columns and all rows except the last column...

case 3: if you want only last row --- df.iloc[-1:,:] & df.iloc[-1,:] this means that you want only the last row...

case 4: if you want all columns and all rows except the last row --- df.iloc[:-1,:] this means that you want all columns and all rows except the last column...

case 5: if you want all columns and all rows except the last row and last column --- df.iloc[:-1,:-1] this means that you want all columns and all rows except the last column and last row...

You CAN ONLY understand Domain driven design by first comprehending what the following are:

What is a domain?

The field for which a system is built. Airport management, insurance sales, coffee shops, orbital flight, you name it.

It's not unusual for an application to span several different domains. For example, an online retail system might be working in the domains of shipping (picking appropriate ways to deliver, depending on items and destination), pricing (including promotions and user-specific pricing by, say, location), and recommendations (calculating related products by purchase history).

What is a model?

"A useful approximation to the problem at hand." -- Gerry Sussman

An Employee class is not a real employee. It models a real employee. We know that the model does not capture everything about real employees, and that's not the point of it. It's only meant to capture what we are interested in for the current context.

Different domains may be interested in different ways to model the same thing. For example, the salary department and the human resources department may model employees in different ways.

What is a domain model?

A model for a domain.

What is Domain-Driven Design (DDD)?

It is a development approach that deeply values the domain model and connects it to the implementation. DDD was coined and initially developed by Eric Evans.

you can convert a string to array with str_split and use foreach

$chars = str_split($str);
foreach($chars as $char){
    // your code
}

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

subscript

extension Array where Element : Equatable {
  public subscript(safe bounds: Range<Int>) -> ArraySlice<Element> {
    if bounds.lowerBound > count { return [] }
    let lower = Swift.max(0, bounds.lowerBound)
    let upper = Swift.max(0, Swift.min(count, bounds.upperBound))
    return self[lower..<upper]
  }
  
  public subscript(safe lower: Int?, _ upper: Int?) -> ArraySlice<Element> {
    let lower = lower ?? 0
    let upper = upper ?? count
    if lower > upper { return [] }
    return self[safe: lower..<upper]
  }
}

returns a copy of this range clamped to the given limiting range.

var arr = [1, 2, 3]
    
arr[safe: 0..<1]    // returns [1]  assert(arr[safe: 0..<1] == [1])
arr[safe: 2..<100]  // returns [3]  assert(arr[safe: 2..<100] == [3])
arr[safe: -100..<0] // returns []   assert(arr[safe: -100..<0] == [])

arr[safe: 0, 1]     // returns [1]  assert(arr[safe: 0, 1] == [1])
arr[safe: 2, 100]   // returns [3]  assert(arr[safe: 2, 100] == [3])
arr[safe: -100, 0]  // returns []   assert(arr[safe: -100, 0] == [])

The exception message says you're trying to connect to the same host (127.0.0.1), while you're stating that your server is running on a different host. Besides the obvious bugs like having "localhost" in the url, or maybe some you might want to check your DNS settings.

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46)

Type "help", "copyright", "credits" or "license" for more information.
>>> import platform, sys
>>> platform.architecture(), sys.maxsize
(('64bit', ''), 2147483647)
>>> ^D
$ arch -x86_64 /usr/local/bin/python2.7

I found this to be a little more accurate:

SELECT
   owner, table_name, TRUNC(sum(bytes)/1024/1024/1024) GB
FROM
(SELECT segment_name table_name, owner, bytes
FROM dba_segments
WHERE segment_type in  ('TABLE','TABLE PARTITION')
UNION ALL
SELECT i.table_name, i.owner, s.bytes

AND   s.owner = i.owner
AND   s.segment_type in ('INDEX','INDEX PARTITION')
UNION ALL

---WHERE owner in UPPER('&owner')
GROUP BY table_name, owner

ORDER BY SUM(bytes) desc

Well, I think nginx by itself doesn't have that in its setup, because the Ubuntu-maintained package does it as a convention to imitate Debian's apache setup. You could create it yourself if you wanted to emulate the same setup.

Create /etc/nginx/sites-available and /etc/nginx/sites-enabled and then edit the http block inside /etc/nginx/nginx.conf and add this line

include /etc/nginx/sites-enabled/*;

Of course, all the files will be inside sites-available, and you'd create a symlink for them inside sites-enabled for those you want enabled.

Is this not easier? For example within an onClickListener?

try {
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/426253597411506"));
    startActivity(intent);
} catch(Exception e) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.facebook.com/appetizerandroid")));
}

PS. Get your id (the large number) from http://graph.facebook.com/[userName]

Globals in Python are global to a module, not across all modules. (Many people are confused by this, because in, say, C, a global is the same across all implementation files unless you explicitly make it static.)

There are different ways to solve this, depending on your actual use case.

Before even going down this path, ask yourself whether this really needs to be global. Maybe you really want a class, with f as an instance method, rather than just a free function? Then you could do something like this:

import module1
thingy1 = module1.Thingy(a=3)
thingy1.f()

If you really do want a global, but it's just there to be used by module1, set it in that module.

import module1
module1.a=3
module1.f()

On the other hand, if a is shared by a whole lot of modules, put it somewhere else, and have everyone import it:

import shared_stuff
import module1
shared_stuff.a = 3
module1.f()

… and, in module1.py:

import shared_stuff
def f():
    print shared_stuff.a

Don't use a from import unless the variable is intended to be a constant. from shared_stuff import a would create a new a variable initialized to whatever shared_stuff.a referred to at the time of the import, and this new a variable would not be affected by assignments to shared_stuff.a.

Or, in the rare case that you really do need it to be truly global everywhere, like a builtin, add it to the builtin module. The exact details differ between Python 2.x and 3.x. In 3.x, it works like this:

import builtins
import module1
builtins.a = 3
module1.f()

I disagree with the accepted answer being "the easiest", particularly if you want to use virtualenv.

You can use the Unofficial Windows Binaries instead. Download the appropriate wheel from there, and install it with pip:

pip install pywin32-219-cp27-none-win32.whl

(Make sure you pick the one for the right version and bitness of Python).

You might be able to get the URL and install it via pip without downloading it first, but they're made it a bit harder to just grab the URL. Probably better to download it and host it somewhere yourself.

What about Date.today.to_time?

You can find the most up to date answer for the value in your project just execute the

mvn3 help:effective-pom

command and find the <build> ... <directory> tag's value in the result aka in the effective-pom. It will show the value of the Super POM unless you have overwritten.

Use <packages xmlns="urn:packages">in the place of <packages>

Usually this happens if something is wrong with the byte array.

File.WriteAllBytes("filename.PDF", Byte[]);

This creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.

Asynchronous implementation of this is also available.

public static System.Threading.Tasks.Task WriteAllBytesAsync 
(string path, byte[] bytes, System.Threading.CancellationToken cancellationToken = null);

You shouldn't use the double-bracket {{ }} syntax within if or ifequal statements, you can simply access the variable there like you would in normal python:

{% if title == source %}
   ...
{% endif %}

You can also use UNION like

SELECT  user_fname ,
        user_lname
FROM    users 
WHERE   user_id = $_GET[id]
UNION
SELECT  user_fname ,
        user_lname
FROM    users 
WHERE   user_parent_id = $_GET[id]

Running yarn on Windows Linux subsystem with Ubunto OS, error "running beyond virtual memory limits, Killing container" I resolved it by disabling virtual memory check in the file yarn-site.xml

<property> <name>yarn.nodemanager.vmem-check-enabled</name> <value>false</value> </property> 

I just wrote this and it looks more clean to me:

const fs = require('fs');
const util = require('util');

const readdir = util.promisify(fs.readdir);
const readFile = util.promisify(fs.readFile);

const readFiles = async dirname => {
    try {
        const filenames = await readdir(dirname);
        console.log({ filenames });
        const files_promise = filenames.map(filename => {
            return readFile(dirname + filename, 'utf-8');
        });
        const response = await Promise.all(files_promise);
        //console.log({ response })
        //return response
        return filenames.reduce((accumlater, filename, currentIndex) => {
            const content = response[currentIndex];
            accumlater[filename] = {
                content,
            };
            return accumlater;
        }, {});
    } catch (error) {
        console.error(error);
    }
};

const main = async () => {

    const response = await readFiles(
        './folder-name',
    );
    console.log({ response });
};

You can modify the response format according to your need. The response format from this code will look like:

{
   "filename-01":{
      "content":"This is the sample content of the file"
   },
   "filename-02":{
      "content":"This is the sample content of the file"
   }
}

In order to understand the trick, one has to know, how Adapters work in general and ArrayAdapter in particular.

Adapters: are objects that are able to bind data structures to widgets, then these widgets are displaying that data in a List or in a Spinner.

So the two questions an Adapter answers are:

1. Which widget or composite view needs to be associated with a data structure(your class' object) for a certain index?
2. How to extract the data from the data structure(your class' object) and how to set field(s) i.e EditText of the widget or composite view according to this data?

ArrayAdapter's answers are:

• Each widget (i.e row.xml OR android.R.layout.simple_spinner_item) for any index is the same, and is inflated from the resource whose ID was given to ArrayAdapter's constructor.
• Each widget is expected to be an instance of TextView (or descendant). The widget's .setText() method will be used with the string format of the item in the supporting data structure. The string format will be obtained by invoking .toString() on the item.

It works properly, I hope it is useful.

I had a similar query and a similar issue.

SELECT
    *
FROM
    Users ru
    LEFT OUTER JOIN 
    (
        SELECT ru1.UserID, COUNT(*)
        FROM Referral r
        LEFT OUTER JOIN Users ru1 ON r.ReferredUserId = ru1.UserID
        GROUP BY ru1.UserID
    ) ReferralTotalCount ON ru.UserID = ReferralTotalCount.UserID

I found that SQL Server was choking on the COUNT(*) column, and was giving me the error No column was specified for column 2.

Putting an alias on the COUNT(*) column fixed the issue.

  SELECT
        *
    FROM
        Users ru
        LEFT OUTER JOIN 
        (
            SELECT ru1.UserID, COUNT(*) AS -->MyCount<--
            FROM Referral r
            LEFT OUTER JOIN Users ru1 ON r.ReferredUserId = ru1.UserID
            GROUP BY ru1.UserID
        ) ReferralTotalCount ON ru.UserID = ReferralTotalCount.UserID

Here's a way:

<html>
    <head>
        <script src="jquery-1.4.2.min.js" type="text/javascript"></script>
        <script type="text/javascript">
            $(document).ready(function(){
                var value = $('input[type="hidden"]')[0].value;
                alert(value.split(/\?/)[1]);
            });
        </script>
    </head>
    <body>
        <input type="hidden" value="/TEST/Name?3" />
    </body>
</html>

I notice a lot of people are recommending Convert.ChangeType - This does work for some cases however as soon as you start involving nullable types you will start receiving InvalidCastExceptions:

http://weblogs.asp.net/pjohnson/archive/2006/02/07/Convert.ChangeType-doesn_2700_t-handle-nullables.aspx

A wrapper was written a few years ago to handle this but that isn't perfect either.

http://weblogs.asp.net/pjohnson/archive/2006/02/07/Convert.ChangeType-doesn_2700_t-handle-nullables.aspx

For your specific case, just use the reduce method of Arrays:

var sumArray = function() {
    // Use one adding function rather than create a new one each
    // time sumArray is called
    function add(a, b) {
        return a + b;
    }

    return function(arr) {
        return arr.reduce(add);
    };
}();

alert( sumArray([2, 3, 4]) );

If DB is SQL Server then

select Convert(varchar(10),CONVERT(date,YourDateColumn,106),103)

[+]is simpler

    String s = "ddjdjdj+kfkfkf";

    if(s.contains ("+"))
    {
        String parts[] = s.split("[+]");
        s =  parts[0]; // i want to strip part after  +
    }
    System.out.println(s);

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

An sql sum of column_name's unique values and sorted by the frequency:

SELECT column_name, COUNT(*) FROM table_name GROUP BY column_name ORDER BY 2 DESC;

(x > 0 for x in list) in that function call creates a generator expression eg.

>>> nums = [1, 2, -1, 9, -5]
>>> genexp = (x > 0 for x in nums)
>>> for x in genexp:
        print x


True
True
False
True
False

Which any uses, and shortcircuits on encountering the first object that evaluates True

This is html part

 <a href="{{route('download',$details->report_id)}}" type="button" class="btn btn-primary download" data-report_id="{{$details->report_id}}" >Download</a>

This is Route :

Route::get('/download/{id}', 'users\UserController@getDownload')->name('download')->middleware('auth');

This is function :

public function getDownload(Request $request,$id)
{
                $file= public_path(). "/pdf/";  //path of your directory
                $headers = array(
                    'Content-Type: application/pdf',
                );
                 return Response::download($file.$pdfName, 'filename.pdf', $headers);      
}

Use table-layout:fixed in the table and word-wrap:break-word in the td.

See this example:

<html>
<head>
   <style>
   table {border-collapse:collapse; table-layout:fixed; width:310px;}
   table td {border:solid 1px #fab; width:100px; word-wrap:break-word;}
   </style>
</head>

<body>
   <table>
      <tr>
         <td>1</td>
         <td>Lorem Ipsum</td>
         <td>Lorem Ipsum is simply dummy text of the printing and typesetting industry. </td>
      </tr>
      <tr>
         <td>2</td>
         <td>LoremIpsumhasbeentheindustry'sstandarddummytexteversincethe1500s,whenanunknown</td>
         <td>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</td>
      </tr>
      <tr>
         <td>3</td>
         <td></td>
         <td>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna...</td>
      </tr>
   </table>
</body>
</html>

DEMO:

table {border-collapse:collapse; table-layout:fixed; width:310px;}_x000D_
       table td {border:solid 1px #fab; width:100px; word-wrap:break-word;}

       <table>_x000D_
          <tr>_x000D_

DateTime? MyDateTime{get;set;}

MyDateTime = (dr["f1"] == DBNull.Value) ? (DateTime?)null : ((DateTime)dr["f1"]);

This worked for me:

$scanresults = Invoke-Expression "& 'C:\Program Files (x86)\Nmap\nmap.exe' -vv -sn 192.168.1.1-150 --open"

sudo chmod 777 DIR_NAME
cd DIR_NAME
git clone https://github.com/mygitusername/kivy.git

should work fine

If you want to do a redirect, you can either:

ViewBag.Error = "error message";

or

TempData["Error"] = "error message";

getDay() returns the day of the week. To get the date, use date.getDate(). getMonth() retrieves the month, but month is zero based, so using getMonth()+1 should give you the right month. Time value seems to be ok here, albeit the hour is 23 here (GMT+1). If you want universal values, add UTC to the methods (e.g. date.getUTCFullYear(), date.getUTCHours())

var timestamp = 1301090400,
date = new Date(timestamp * 1000),
datevalues = [
   date.getFullYear(),
   date.getMonth()+1,
   date.getDate(),
   date.getHours(),
   date.getMinutes(),
   date.getSeconds(),
];
alert(datevalues); //=> [2011, 3, 25, 23, 0, 0]

Use System.Security.Principal.WindowsIdentity.GetCurrent().Name.

This will get the current logged-in Windows user.

I successfully put a portable version of libreoffice on my host's webserver, which I call with PHP to do a commandline conversion from .docx, etc. to pdf. on the fly. I do not have admin rights on my host's webserver. Here is my blog post of what I did:

http://geekswithblogs.net/robertphyatt/archive/2011/11/19/converting-.docx-to-pdf-or-.doc-to-pdf-or-.doc.aspx

Yay! Convert directly from .docx or .odt to .pdf using PHP with LibreOffice (OpenOffice's successor)!

For same error code i had quite different reason, I'm sharing here to help

I had web api action like below

public IHttpActionResult GetBooks (int id)

I changed the method to accept two parameters category and author so i changed the parameters as below, i also put the attribute [Httppost]

public IHttpActionResult GetBooks (int category, int author)

I also changed ajax options like below and at this point i start getting error 405 method not allowed

var options = {
    url: '/api/books/GetBooks',
    type: 'POST',
    dataType: 'json',
    cache: false,
    traditional: true, 
    data: {
        category: 1,
        author: 15
    }
}

When i created class for web api action parameters like below error was gone

public class BookParam
{
    public int Category { get; set; }
    public int Author { get; set; }
}
public IHttpActionResult GetBooks (BookParam param)

If you want to put the new module into a custom location that your cpan shell isn't configured to use, then perhaps, the following will be handy.

 #wget <URL to the module.tgz>
 ##unpack

./Build destdir=$HOME install_base=$HOME install

gyp ERR! configure error gyp ERR! stack Error: Can't find Python executable "python", you can set the PYT HON env variable.

This means the Python env. variable should point to the executable python file, in my case: SET PYTHON=C:\work\_env\Python27\python.exe

You can find a continuously updated list of sensitive sinks (exploitable php functions) and their parameters in RIPS /config/sinks.php, a static source code analyser for vulnerabilities in PHP applications that also detects PHP backdoors.

I am new to ruby and had to just deal with understanding the following weirdness. Might help out someone else in the future. In the end it is as was mentioned above, where 2 functions (def myvar, def myvar=) both get implicitly for accessing @myvar, but these methods can be overridden by local declarations.

class Foo
  attr_accessor 'myvar'
  def initialize
    @myvar = "A"
    myvar = "B"
    puts @myvar # A
    puts myvar # B - myvar declared above overrides myvar method
  end

  def test
    puts @myvar # A
    puts myvar # A - coming from myvar accessor

    myvar = "C" # local myvar overrides accessor
    puts @myvar # A
    puts myvar # C

    send "myvar=", "E" # not running "myvar =", but instead calls setter for @myvar
    puts @myvar # E
    puts myvar # C
  end
end

Use Attribute Equals Selector

$('.slide-link[data-slide="0"]').addClass('active');

Fiddle Demo

.find()

it works down the tree

Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.

Also if your working directory is different than you can use lpDirectory

    procInfo = ShellExecuteEx(nShow=showCmd,
                          lpVerb=lpVerb,
                          lpFile=cmd,
                          lpDirectory= unicode(direc),
                          lpParameters=params)

Will come handy if changing the path is not a desirable option remove unicode for python 3.X

The openssl documentation says that file supplied as the -in argument must be in PEM format.

Turns out that, contrary to the CA's manual, the certificate returned by the CA which I stored in myCert.cer is not PEM format rather it is PKCS7.

In order to create my .p12, I had to first convert the certificate to PEM:

openssl pkcs7 -in myCert.cer -print_certs -out certs.pem

and then execute

openssl pkcs12 -export -out keyStore.p12 -inkey myKey.pem -in certs.pem

Perhaps you should divide your content like such using floats:

<div style="overflow: auto;">
    <div style="float: left; width: 600px;">
        Here is my content!
    </div>
    <div style="float: right; width: 300px;">
        Here is my sidebar!
    </div>
</div>

Notice the overflow: auto;, this is to ensure that you have some height to your container. Floating things takes them out of the DOM, to ensure that your elements below don't overlap your wandering floats, set a container div to have an overflow: auto (or overflow: hidden) to ensure that floats are accounted for when drawing your height. Check out more information on floats and how to use them here.

Open angular.json file and find budgets keyword.

It should look like:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "2mb",
          "maximumError": "5mb"
       }
    ]

As you’ve probably guessed you can increase the maximumWarning value to prevent this warning, i.e.:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "4mb", <===
          "maximumError": "5mb"
       }
    ]

What does budgets mean?

A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.

In our case budget is the limit for bundle sizes.

• https://github.com/webpack/webpack/issues/3216
• https://angular.io/guide/build#configure-size-budgets

#!/usr/bin/env ruby

You are specifying the -i option:

-i, --include

(HTTP) Include the HTTP-header in the output. The HTTP-header includes things like server-name, date of the document, HTTP-version and more...

Simply remove that option from your command line:

response=$(curl -sb -H "Accept: application/json" "http://host:8080/some/resource")

SELECT prosrc FROM pg_proc WHERE proname = 'function_name';

This tells the function handler how to invoke the function. It might be the actual source code of the function for interpreted languages, a link symbol, a file name, or just about anything else, depending on the implementation language/call convention

Tie::File is what you need:

Synopsis

# This file documents Tie::File version 0.98
use Tie::File;

tie @array, 'Tie::File', 'filename' or die ...;

$array[13] = 'blah';     # line 13 of the file is now 'blah'
print $array[42];        # display line 42 of the file

$n_recs = @array;        # how many records are in the file?
$#array -= 2;            # chop two records off the end


for (@array) {
  s/PERL/Perl/g;         # Replace PERL with Perl everywhere in the file
}

# These are just like regular push, pop, unshift, shift, and splice
# Except that they modify the file in the way you would expect

push @array, new recs...;
my $r1 = pop @array;
unshift @array, new recs...;
my $r2 = shift @array;
@old_recs = splice @array, 3, 7, new recs...;

untie @array;            # all finished

Try the 'Import and Export Data (32-bit)' tool. Available after installing MS SQL Management Studio Express 2012.

With this tool it's very easy to select a database, a table or to insert your own SQL query and choose a destination (A MS Excel file for example).

You can get other constructors with getConstructor(...).

Take a look at cat /proc/stat

grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'

EDIT please read comments before copy-paste this or using this for any serious work. This was not tested nor used, it's an idea for people who do not want to install a utility or for something that works in any distribution. Some people think you can "apt-get install" anything.

NOTE: this is not the current CPU usage, but the overall CPU usage in all the cores since the system bootup. This could be very different from the current CPU usage. To get the current value top (or similar tool) must be used.

Current CPU usage can be potentially calculated with:

awk '{u=$2+$4; t=$2+$4+$5; if (NR==1){u1=u; t1=t;} else print ($2+$4-u1) * 100 / (t-t1) "%"; }' \
<(grep 'cpu ' /proc/stat) <(sleep 1;grep 'cpu ' /proc/stat)

No one said, but array_push only pushes a element to the END OF THE ARRAY, where $array[index] can insert a value at any given index. Big difference.

You can set the session time out in php.ini. The default value is 1440 seconds

session.gc_maxlifetime = 1440

; NOTE: If you are using the subdirectory option for storing session files
;       (see session.save_path above), then garbage collection does *not*
;       happen automatically.  You will need to do your own garbage
;       collection through a shell script, cron entry, or some other method.
;       For example, the following script would is the equivalent of
;       setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes):
;          find /path/to/sessions -cmin +24 -type f | xargs rm

You can use jQuery's $.map.

var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' },
keys = $.map(foo, function(v, i){
  return i;
});

In C++11, you can use std::any_of instead.

An example to find if there is any zero in the array:

std::array<int,3> foo = {0,1,-1};
if ( std::any_of(foo.begin(), foo.end(), [](int i){return i==0;}) )
std::cout << "zero found...";

In case you are using axios and trying via a service call.

URL: https://react-16-demo.firebaseio.com/
Schema Name: todos
Key: -Lhu8a0uoSRixdmECYPE

axios.delete(`https://react-16-demo.firebaseio.com/todos/-Lhu8a0uoSRixdmECYPE.json`). then();

can help.

I think it may be the sudo has no access to get ORACLE_HOME.You can do like this.

sudo visudo

modify the text add

Defaults env_keep += "ORACLE_HOME"

then

sudo python setup.py build install

Any Primitive data type like int,boolean, or float etc can't store the null(lateral),since java has provided Wrapper class for storing the same like int to Integer,boolean to Boolean.

Eg: Integer i=null;

To change the text colour of UILable at runtime use NSAttributedText and do not set UILable.textColor.

Above code worked well for me in Xcode 10.2.1 and Swift 5.

Lot's of regex here, despite the fact i really like them this way might be more stable to me:

$resultCurl=curl_exec($curl); //get curl result
//Optional line if you want to store the http status code
$headerHttpCode=curl_getinfo($curl,CURLINFO_HTTP_CODE);

//let's use dom and xpath
$dom = new \DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTML($resultCurl, LIBXML_HTML_NODEFDTD);
libxml_use_internal_errors(false);
$xpath = new \DOMXPath($dom);
$head=$xpath->query("/html/body/p/a/@href");

$newUrl=$head[0]->nodeValue;

The location part is a link in the HTML sent by apache. So Xpath is perfect to recover it.

You need to create a comparator. I am not sure why each value needs its own map but here is what the comparator would look like:

class ListMapComparator implements Comparator {
    public int compare(Object obj1, Object obj2) {
         Map<String, String> test1 = (Map<String, String>) obj1;
         Map<String, String> test2 = (Map<String, String>) obj2;
         return test1.get("name").compareTo(test2.get("name"));
    }
}

You can see it working with your above example with this:

public class MapSort {
    public List<Map<String, String>> testMap() {
         List<Map<String, String>> list = new ArrayList<Map<String, String>>();
         Map<String, String> myMap1 = new HashMap<String, String>();
         myMap1.put("name", "Josh");
         Map<String, String> myMap2 = new HashMap<String, String>();
         myMap2.put("name", "Anna");

         Map<String, String> myMap3 = new HashMap<String, String>();
         myMap3.put("name", "Bernie");


         list.add(myMap1);
         list.add(myMap2);
         list.add(myMap3);

         return list;
    }

    public static void main(String[] args) {
         MapSort ms = new MapSort();
         List<Map<String, String>> testMap = ms.testMap();
         System.out.println("Before Sort: " + testMap);
         Collections.sort(testMap, new ListMapComparator());
         System.out.println("After Sort: " + testMap);
    }
}

You will have some type safe warnings because I did not worry about these. Hope that helps.

Suppose a 9800GT GPU:

• it has 14 multiprocessors (SM)
• each SM has 8 thread-processors (AKA stream-processors, SP or cores)
• allows up to 512 threads per block
• warpsize is 32 (which means each of the 14x8=112 thread-processors can schedule up to 32 threads)

https://www.tutorialspoint.com/cuda/cuda_threads.htm

A block cannot have more active threads than 512 therefore __syncthreads can only synchronize limited number of threads. i.e. If you execute the following with 600 threads:

func1();
__syncthreads();
func2();
__syncthreads();

then the kernel must run twice and the order of execution will be:

1. func1 is executed for the first 512 threads
2. func2 is executed for the first 512 threads
3. func1 is executed for the remaining threads
4. func2 is executed for the remaining threads

Note:

The main point is __syncthreads is a block-wide operation and it does not synchronize all threads.

I'm not sure about the exact number of threads that __syncthreads can synchronize, since you can create a block with more than 512 threads and let the warp handle the scheduling. To my understanding it's more accurate to say: func1 is executed at least for the first 512 threads.

Before I edited this answer (back in 2010) I measured 14x8x32 threads were synchronized using __syncthreads.

I would greatly appreciate if someone test this again for a more accurate piece of information.

router.navigate vs router.navigateByUrl

router.navigate is just a convenience method that wraps router.navigateByUrl, it boils down to:

navigate(commands: any[], extras) {
    return router.navigateByUrl(router.createUrlTree(commands, extras), extras);
}

As mentioned in other answers router.navigateByUrl will only accept absolute URLs:

// This will work
router.navigateByUrl("http://localhost/team/33/user/11")
// This WON'T work even though relativeTo parameter is in the signature
router.navigateByUrl("../22", {relativeTo: route})

All the relative calculations are done by router.createUrlTree and router.navigate. Array syntax is used to treat every array element as a URL modifying "command". E.g. ".." - go up, "path" - go down, {expand: true} - add query param, etc.. You can use it like this:

// create /team/33/user/11
router.navigate(['/team', 33, 'user', 11]);

// assuming the current url is `/team/33/user/11` and the route points to `user/11`

// navigate to /team/33/user/11/details
router.navigate(['details'], {relativeTo: route});

// navigate to /team/33/user/22
router.navigate(['../22'], {relativeTo: route});

// navigate to /team/44/user/22
router.navigate(['../../team/44/user/22'], {relativeTo: route});

That {relativeTo: route} parameter is important as that's what router will use as the root for relative operations.

Get it through your component's constructor:

  // In my-awesome.component.ts:

  constructor(private route: ActivatedRoute, private router: Router) {}
  
  // Example call
  onNavigateClick() {
    // Navigates to a parent component
    this.router.navigate([..], { relativeTo: this.route })
  }

routerLink directive

Nicest thing about this directive is that it will retrieve the ActivatedRoute for you. Under the hood it's using already familiar:

router.navigateByUrl(router.createUrlTree(commands, { relativeTo: route }), { relativeTo: route });

Following variants will produce identical result:

[routerLink]="['../..']"

// if the string parameter is passed it will be wrapped into an array
routerLink="../.."

In my case (backend), I was using res.send(token);

Everything got fixed when I changed to res.send(data);

You may want to check this if everything is working and posting as intended, but the error keeps popping up in your front-end.

Small but IMPORTANT notices:

1. FB.getLoginStatus must be called after FB.init, otherwise it will not fire the event.

2. you can use FB.Event.subscribe('auth.statusChange', callback), but it will not fire when user is not logged in facebook.

Here is the working example with both functions

window.fbAsyncInit = function() {
    FB.Event.subscribe('auth.statusChange', function(response) {
        console.log( "FB.Event.subscribe auth.statusChange" );
        console.log( response );
    });

    FB.init({
        appId   : "YOUR APP KEY HERE",
        cookie  : true,  // enable cookies to allow the server to access
                // the session
        xfbml   : true,  // parse social plugins on this page
        version : 'v2.1', // use version 2.1
        status  : true
    });

    FB.getLoginStatus(function(response){
        console.log( "FB.getLoginStatus" );
        console.log( response );
    });

};

// Load the SDK asynchronously

Header files can contain any valid C code, since they are injected into the compilation unit by the pre-processor prior to compilation.

If a header file contains a function, and is included by multiple .c files, each .c file will get a copy of that function and create a symbol for it. The linker will complain about the duplicate symbols.

It is technically possible to create static functions in a header file for inclusion in multiple .c files. Though this is generally not done because it breaks from the convention that code is found in .c files and declarations are found in .h files.

See the discussions in C/C++: Static function in header file, what does it mean? for more explanation.

This answer assumes that you have python3.6 installed. For python3.7, replace 3.6 with 3.7. For python3.8, replace 3.6 with 3.8, but it may also first require the python3.8-distutils package.

Installation with sudo

With regard to installing pip, using curl (instead of wget) avoids writing the file to disk.

curl https://bootstrap.pypa.io/get-pip.py | sudo -H python3.6

The -H flag is evidently necessary with sudo in order to prevent errors such as the following when installing pip for an updated python interpreter:

The directory '/home/someuser/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

The directory '/home/someuser/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Installation without sudo

curl https://bootstrap.pypa.io/get-pip.py | python3.6 - --user

This may sometimes give a warning such as:

WARNING: The script wheel is installed in '/home/ubuntu/.local/bin' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

Verification

After this, pip, pip3, and pip3.6 can all be expected to point to the same target:

$ (pip -V && pip3 -V && pip3.6 -V) | uniq
pip 18.0 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Of course you can alternatively use python3.6 -m pip as well.

$ python3.6 -m pip -V
pip 18.0 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Have you looked into using a HorizontalScrollView to wrap your list items? That will allow each of your list items to be horizontally scrollable (what you put in there is up to you, and can make them dynamic items similar to ListView). This will work well if you are only after a single row of items.

public static boolean isEmpty(String ptext) {
 return ptext == null || ptext.trim().length() == 0;
}

public static boolean isBlank(String ptext) {
 return ptext == null || ptext.trim().length() == 0;
}

Both have the same code how will isBlank handle white spaces probably you meant isBlankString this has the code for handling whitespaces.

public static boolean isBlankString( String pString ) {
 int strLength;
 if( pString == null || (strLength = pString.length()) == 0)
 return true;
 for(int i=0; i < strLength; i++)
 if(!Character.isWhitespace(pString.charAt(i)))
 return false;
 return false;
}

Since asked and answered by the same person, I'll add a npm link as an alternative.

from docs:

This is handy for installing your own stuff, so that you can work on it and test it iteratively without having to continually rebuild.

cd ~/projects/node-bloggy  # go into the dir of your main project
npm link ../node-redis     # link the dir of your dependency

[Edit] As of NPM 2.0, you can declare local dependencies in package.json

"dependencies": {
    "bar": "file:../foo/bar"
  }

you can't animate every property,

here's a reference to which are the animatable properties

visibility is animatable while display isn't...

in your case you could also animate opacity or height depending of the kind of effect you want to render_

fiddle with opacity animation

You can try this:

this.activatedRoute.paramMap.subscribe(x => {
    let id = x.get('id');
    console.log(id);  
});

From Windows Vista on you have the TIMEOUT and SLEEP commands, but to use them on Windows XP or Windows Server 2003, you'll need the Windows Server 2003 resource tool kit.

Here you have a good overview of sleep alternatives (the ping approach is the most popular as it will work on every Windows machine), but there's (at least) one not mentioned which (ab)uses the W32TM (Time Service) command:

w32tm /stripchart /computer:localhost /period:1 /dataonly /samples:N  >nul 2>&1

Where you should replace the N with the seconds you want to pause. Also, it will work on every Windows system without prerequisites.

Typeperf can also be used:

typeperf "\System\Processor Queue Length" -si N -sc 1 >nul

With mshta and javascript (can be used for sleep under a second):

start "" /wait /min /realtime mshta "javascript:setTimeout(function(){close();},5000)"

This should be even more precise (for waiting under a second) - self compiling executable relying on .net:

@if (@X)==(@Y) @end /* JScript comment
@echo off
setlocal
::del %~n0.exe /q /f
::
:: For precision better call this like
:: call waitMS 500
:: in order to skip compilation in case there's already built .exe
:: as without pointed extension first the .exe will be called due to the ordering in PATEXT variable
::
::
for /f "tokens=* delims=" %%v in ('dir /b /s /a:-d  /o:-n "%SystemRoot%\Microsoft.NET\Framework\*jsc.exe"') do (
   set "jsc=%%v"
)

if not exist "%~n0.exe" (
    "%jsc%" /nologo /w:0 /out:"%~n0.exe" "%~dpsfnx0"
)


%~n0.exe %*

endlocal & exit /b %errorlevel%


*/


import System;
import System.Threading;

var arguments:String[] = Environment.GetCommandLineArgs();
function printHelp(){
    Console.WriteLine(arguments[0]+" N");
    Console.WriteLine(" N - milliseconds to wait");
    Environment.Exit(0);    
}

if(arguments.length<2){
    printHelp();
}

try{
    var wait:Int32=Int32.Parse(arguments[1]);
    System.Threading.Thread.Sleep(wait);
}catch(err){
    Console.WriteLine('Invalid Number passed');
    Environment.Exit(1);
}

I find the second style (declaration + initialization in one go) superior. Reasons:

• It makes it clear at a glance how the variable is initialized. Typically, when reading a program and coming across a variable, you'll first go to its declaration (often automatic in IDEs). With style 2, you see the default value right away. With style 1, you need to look at the constructor as well.
• If you have more than one constructor, you don't have to repeat the initializations (and you cannot forget them).

Of course, if the initialization value is different in different constructors (or even calculated in the constructor), you must do it in the constructor.

I was struggling for a while with this problem. Some of the solutions worked however some of my views where still being pushed up while others weren't... So it didn't completely solve my problem. In the end, what did the job was adding the following line of code to my manifest in the activity tag...

android:windowSoftInputMode="stateHidden|adjustPan|adjustResize"

Good luck

I use this and it works right

@Id
@GeneratedValue(generator = "SEC_ODON", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "SEC_ODON", sequenceName = "SO.SEC_ODON",allocationSize=1)
@Column(name="ID_ODON", unique=true, nullable=false, precision=10, scale=0)
public Long getIdOdon() {
    return this.idOdon;
}

node-crontab allows you to edit system cron jobs from node.js. Using this library will allow you to run programs even after your main process termintates. Disclaimer: I'm the developer.

You could try to find it via the command line.

find / -type f -name "php.ini"

Or you could add the following to a .htaccess file in the root of your site.

php_value max_input_vars 6000
php_value suhosin.get.max_vars 6000
php_value suhosin.post.max_vars 6000
php_value suhosin.request.max_vars 6000

function sum(){
    var x,y,z;
    x = Number(document.getElementById("input1").value);
    y = Number(document.getElementById("input2").value);
    z = x + y;
    document.getElementById("result").innerHTML = z ;
}

You can do this with a pivot table and add a line with the pourcentage for each category like brettdj showed in his answer. But if you want to keep your data as it is, there is a solution by using some javascript.

Javascript is a powerful language offering a lot of useful data visualization libraries like plotly.js.

Here is a working code I have written for you:

https://www.funfun.io/1/#/edit/5a58c6368dfd67466879ed27

In this example, I use a Json file to get the data from the embedded spreadsheet, so I can use it in my javascript code and create a bar chart.

I calculate the percentage by adding the values of all the category present in the table and using this formula (you can see it in the script.js file): Percentage (%) = 100 x partial value / total value

It automatically calculates the total and pourcentage even if you add more categories.

I used plotly.js to create my chart, it has a good documentation and lots of examples for beginners, this code gets all the option you want to use:

var trace1 = {
    x: xValue, 
    y: data,
    type: 'bar',
    text: yValue,
    textposition: 'auto',
    hoverinfo: 'none',
    marker: {
    color: 'yellow',
    opacity: 0.6,
    line: {
      color: 'yellow',
      width: 1.5
    }
  }
};

It is rather self explanatory, the text is where you put the percentage.

Once you've made your chart you can load it in excel by passing the URL in the Funfun add-in. Here is how it looks like with my example:

I know it is an old post but I hope it helps people with the same problem !

Disclosure : I’m a developer of funfun

You can allow multiple POST parameters by using the MultiPostParameterBinding class from https://github.com/keith5000/MultiPostParameterBinding

To use it:

1) Download the code in the Source folder and add it to your Web API project or any other project in the solution.

2) Use attribute [MultiPostParameters] on the action methods that need to support multiple POST parameters.

[MultiPostParameters]
public string DoSomething(CustomType param1, CustomType param2, string param3) { ... }

3) Add this line in Global.asax.cs to the Application_Start method anywhere before the call to GlobalConfiguration.Configure(WebApiConfig.Register):

GlobalConfiguration.Configuration.ParameterBindingRules.Insert(0, MultiPostParameterBinding.CreateBindingForMarkedParameters);

4) Have your clients pass the parameters as properties of an object. An example JSON object for the DoSomething(param1, param2, param3) method is:

{ param1:{ Text:"" }, param2:{ Text:"" }, param3:"" }

Example JQuery:

$.ajax({
    data: JSON.stringify({ param1:{ Text:"" }, param2:{ Text:"" }, param3:"" }),
    url: '/MyService/DoSomething',
    contentType: "application/json", method: "POST", processData: false
})
.success(function (result) { ... });

Disclaimer: I am directly associated with the linked resource.

Detecting peaks in a spectrum in a reliable way has been studied quite a bit, for example all the work on sinusoidal modelling for music/audio signals in the 80ies. Look for "Sinusoidal Modeling" in the literature.

If your signals are as clean as the example, a simple "give me something with an amplitude higher than N neighbours" should work reasonably well. If you have noisy signals, a simple but effective way is to look at your peaks in time, to track them: you then detect spectral lines instead of spectral peaks. IOW, you compute the FFT on a sliding window of your signal, to get a set of spectrum in time (also called spectrogram). You then look at the evolution of the spectral peak in time (i.e. in consecutive windows).

With docker-compose, you could set context folder:

#docker-compose.yml
version: '3.3'    
services:
      yourservice:
        build:
          context: ./
          dockerfile: ./docker/yourservice/Dockerfile

Do not use the ToList() method as in the accepted answer !

Running SQL profiler, I verified and found that ToList() function gets all the records from the database. It is really bad performance !!

I would have run this query by pure sql command as follows:

string query = "Update YourTable Set ... Where ...";    
context.Database.ExecuteSqlCommandAsync(query, new SqlParameter("@ColumnY", value1), new SqlParameter("@ColumnZ", value2));

This would operate the update in one-shot without selecting even one row.

I wasn't able to get Surya's and Matteo's solutions to work. For example, "(#f1)" was just displayed as text, and didn't become a link. However, their solutions led me to slightly different solution. (I also formatted the footnote and the link back to the original superscript a bit differently.)

In the body of the text:

Yadda yadda<a href="#note1" id="note1ref"><sup>1</sup></a>

At the end of the document:

<a id="note1" href="#note1ref"><sup>1</sup></a>Here is the footnote text.

Clicking on the superscript in the footnote returns to the superscript in the original text.

The problem with this method is, at least when running by bash.exe on Windows, that it will create a new process every time which will remain dormant.

ssh-agent bash -c 'ssh-add /somewhere/yourkey; git clone [email protected]:user/project.git'

If you want want to use that for syncig repo on schedule then you need to add "&& ssh-agent -k" at the end.

Something like:

ssh-agent bash -c 'ssh-add C:/Users/user/.ssh/your_key; git -C "C:\Path\to\your\repo" pull && ssh-agent -k' 

ssh-agent -k will kill the process when it's done.

Initializing a 2D matrix of size m X n with 0

m,n = map(int,input().split())
l = [[0 for i in range(m)] for j in range(n)]
print(l)

Look into the Dimensions plugin, specifically scrollTop()/scrollLeft(). Information can be found at http://api.jquery.com/scrollTop.

Check out Marker Clusterer for V3 - this library clusters nearby points into a group marker. The map zooms in when the clusters are clicked. I'd imagine when zoomed right in you'd still have the same problem with markers on the same spot though.

To answer your question title, "How to use Rank() in SQL Server," this is how it works:

I will use this set of data as an example:

create table #tmp
(
  column1 varchar(3),
  column2 varchar(5),
  column3 datetime,
  column4 int
)

insert into #tmp values ('AAA', 'SKA', '2013-02-01 00:00:00', 10)
insert into #tmp values ('AAA', 'SKA', '2013-01-31 00:00:00', 15)
insert into #tmp values ('AAA', 'SKB', '2013-01-31 00:00:00', 20)
insert into #tmp values ('AAA', 'SKB', '2013-01-15 00:00:00', 5)
insert into #tmp values ('AAA', 'SKC', '2013-02-01 00:00:00', 25)

You have a partition which basically specifies grouping.

In this example, if you partition by column2, the rank function will create ranks for groups of column2 values. There will be different ranks for rows where column2 = 'SKA' than rows where column2 = 'SKB' and so on.

The ranks are decided like this: The rank for every record is one plus the number of ranks that come before it in its partition. The rank will only increment when one of the fields you selected (other than the partitioned field(s)) is different than the ones that come before it. If all of the selected fields are the same, then the ranks will tie and both will be assigned the value, one.

Knowing this, if we only wanted to select one value from each group in column two, we could use this query:

with cte as 
(
  select *, 
  rank() over (partition by column2 
             order by column3) rnk
  from t

) select * from cte where rnk = 1 order by column3;

Result:

COLUMN1 | COLUMN2   | COLUMN3                           |COLUMN4 | RNK
------------------------------------------------------------------------------
AAA     | SKB   | January, 15 2013 00:00:00+0000    |5   | 1
AAA     | SKA   | January, 31 2013 00:00:00+0000    |15  | 1
AAA     | SKC   | February, 01 2013 00:00:00+0000   |25  | 1

SQL DEMO

If all your trying to do is fill the div this might help someone else, if aspect ratio is not important, is responsive.

.img-fill > img {
  min-height: 100%;
  min-width: 100%;  
}

Here's some code I use to deal with this.

First we show the element, which will typically set the display type to "block" via .show() function, and then set the CSS rule to "visible":

jQuery( '.element' ).show().css( 'visibility', 'visible' );

Or, assuming that the class that is hiding the element is called hidden, such as in Twitter Bootstrap, toggleClass() can be useful:

jQuery( '.element' ).toggleClass( 'hidden' );

Lastly, if you want to chain functions, perhaps with fancy with a fading effect, you can do it like so:

jQuery( '.element' ).css( 'visibility', 'visible' ).fadeIn( 5000 );

It works for me, but some differences:

• I have no welcome-file-list in web.xml
• I have no @RequestMapping at class level.
• And at method level, just @RequestMapping("/")

I know these are no great differences, but I'm pretty sure (I'm not at work now) this is my configuration and it works with Spring MVC 3.0.5.

One more thing. You don't show your dispatcher configuration in web.xml, but maybe you have some preffix. It has to be something like this:

<servlet-mapping>
    <servlet-name>myServletName</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

If this is not your case, you'll need an url-rewrite filter or try the redirect solution.

EDIT: Answering your question, my view resolver configuration is a little different too:

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/view/" />
    <property name="suffix" value=".jsp" />
</bean>

The selector should not be #input. That means a field with id="input" which is not your case. You want:

$('#chag_sort').val(sort2);

Or if your hidden input didn't have an unique id but only a name="chag_sort":

$('input[name="chag_sort"]').val(sort2);

How to rename com.example.app to com.android.app:

1. in package com.example.app select example

2. Shift + F6

3. choose rename package

4. rename example to android

5. confirm do refactor

I solved it by switching tohttp protocol from the file protocol.

• you can use "live-server" extension in VS code,
• or, on node, use live-server [dirPath]

Instead of defining: COLUMN_HEADINGS("columnHeadings")

Try defining it as: COLUMNHEADINGS("columnHeadings")

Then when you call getByName(String name) method, call it with the upper-cased String like this: getByName(myStringVariable.toUpperCase())

I had the same problem as you, and this worked for me.

When not told otherwise commands take over the foreground. You only have one "foreground" process running in a single shell session. The & symbol instructs commands to run in a background process and immediately returns to the command line for additional commands.

sh my_script.sh &

A background process will not stay alive after the shell session is closed. SIGHUP terminates all running processes. By default anyway. If your command is long-running or runs indefinitely (ie: microservice) you need to pr-pend it with nohup so it remains running after you disconnect from the session:

nohup sh my_script.sh &

EDIT: There does appear to be a gray area regarding the closing of background processes when & is used. Just be aware that the shell may close your process depending on your OS and local configurations (particularly on CENTOS/RHEL): https://serverfault.com/a/117157.

Much has changed for MySQL 8. I've found the following modification of the MySQL 8.0 "How to Reset the Root Password" documentation works with Mac OS X.

Create a temp file $HOME/mysql.root.txt with the SQL to update the root password:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '<new-password>';

This uses mysql_native_password to avoid the Authentication plugin 'caching_sha2_password' cannot be loaded error, which I get if I omit the option.

Stop the server, start with an --init-file option to set the root password, then restart the server:

mysql.server stop mysql.server start --init-file=$HOME/mysql.root.txt mysql.server stop mysql.server start

SELECT * from Product_sales where
(From_date BETWEEN '2013-01-03'AND '2013-01-09') OR 
(To_date BETWEEN '2013-01-03' AND '2013-01-09') OR 
(From_date <= '2013-01-03' AND To_date >= '2013-01-09')

You have to cover all possibilities. From_Date or To_Date could be between your date range or the record dates could cover the whole range.

If one of From_date or To_date is between the dates, or From_date is less than start date and To_date is greater than the end date; then this row should be returned.

Use this regular expression to match ten digits only:

@"^\d{10}$"

To find a sequence of ten consecutive digits anywhere in a string, use:

@"\d{10}"

Note that this will also find the first 10 digits of an 11 digit number. To search anywhere in the string for exactly 10 consecutive digits and not more you can use negative lookarounds:

@"(?<!\d)\d{10}(?!\d)"

Not only are you reading the whole of each file into memory, but also you laboriously replicate the information in a table called list_of_lines.

You have a secondary problem: your choices of variable names severely obfuscate what you are doing.

Here is your script rewritten with the readlines() caper removed and with meaningful names:

file_A1_B1 = open("A1_B1_100000.txt", "r")
file_A2_B2 = open("A2_B2_100000.txt", "r")
file_A1_B2 = open("A1_B2_100000.txt", "r")
file_A2_B1 = open("A2_B1_100000.txt", "r")
file_write = open ("average_generations.txt", "w")
mutation_average = open("mutation_average", "w") # not used
files = [file_A2_B2,file_A2_B2,file_A1_B2,file_A2_B1]
for afile in files:
    table = []
    for aline in afile:
        values = aline.split('\t')
        values.remove('\n') # why?
        table.append(values)
    row_count = len(table)
    row0length = len(table[0])
    print_counter = 4
    for column_index in range(row0length):
        column_total = 0
        for row_index in range(row_count):
            number = float(table[row_index][column_index])
            column_total = column_total + number
        column_average = column_total/row_count
        print column_average
        if print_counter == 4:
            file_write.write(str(column_average)+'\n')
            print_counter = 0
        print_counter +=1
file_write.write('\n')

It rapidly becomes apparent that (1) you are calculating column averages (2) the obfuscation led some others to think you were calculating row averages.

As you are calculating column averages, no output is required until the end of each file, and the amount of extra memory actually required is proportional to the number of columns.

Here is a revised version of the outer loop code:

for afile in files:
    for row_count, aline in enumerate(afile, start=1):
        values = aline.split('\t')
        values.remove('\n') # why?
        fvalues = map(float, values)
        if row_count == 1:
            row0length = len(fvalues)
            column_index_range = range(row0length)
            column_totals = fvalues
        else:
            assert len(fvalues) == row0length
            for column_index in column_index_range:
                column_totals[column_index] += fvalues[column_index]
    print_counter = 4
    for column_index in column_index_range:
        column_average = column_totals[column_index] / row_count
        print column_average
        if print_counter == 4:
            file_write.write(str(column_average)+'\n')
            print_counter = 0
        print_counter +=1

Found this example... Will test...

import java.text.DecimalFormat;
class TestingAndQualityAssuranceDepartment
{
    public static void main(String [] args)
    {
        int x=1;
        DecimalFormat df = new DecimalFormat("00");
        System.out.println(df.format(x));
    }
}

Tested this and:

String.format("%05d",number);

Both work, for my purposes I think String.Format is better and more succinct.

Some of the other answers are okay but I ended up mixing and matching a few of them to rather come up with this :

@IBAction func showAlert(sender: AnyObject) {
    let alert = UIAlertController(title: "Title", message: "Please Select an Option", preferredStyle: .actionSheet)
    
    alert.addAction(UIAlertAction(title: "Approve", style: .default , handler:{ (UIAlertAction)in
        print("User click Approve button")
    }))
    
    alert.addAction(UIAlertAction(title: "Edit", style: .default , handler:{ (UIAlertAction)in
        print("User click Edit button")
    }))

    alert.addAction(UIAlertAction(title: "Delete", style: .destructive , handler:{ (UIAlertAction)in
        print("User click Delete button")
    }))
    
    alert.addAction(UIAlertAction(title: "Dismiss", style: .cancel, handler:{ (UIAlertAction)in
        print("User click Dismiss button")
    }))

    
    //uncomment for iPad Support
    //alert.popoverPresentationController?.sourceView = self.view

    self.present(alert, animated: true, completion: {
        print("completion block")
    })
}

Enjoy :)

As the @Jordan Stefanelli answer: If you encounter the same problem as me that the integrated Terminal cannot read input from user as below hanging (env. Windows 10)

my solution was to replace cygwin's gdb and g ++ with mingw64's.

then the input output are normal

also you can enable "external console" option to solve it:)

you can change it by enabling "externalConsole":true in the launch.json then you will get a pop up console window that you can type in.

Old question - but I recently needed this along with the row count... here is a query for both - sorted by row count desc:

SELECT t.owner, 
       t.table_name, 
       t.num_rows, 
       Count(*) 
FROM   all_tables t 
       LEFT JOIN all_tab_columns c 
              ON t.table_name = c.table_name 
WHERE  num_rows IS NOT NULL 
GROUP  BY t.owner, 
          t.table_name, 
          t.num_rows 
ORDER  BY t.num_rows DESC; 

I'm going to break from the herd on this one and provide an alternate point of view:

Never create classes.

Reliance on classes has a significant tendency to cause coders to create bloated and slow code. Classes getting passed around (since they're objects) take a lot more computational power than calling a function and passing a string or two. Proper naming conventions on functions can do pretty much everything creating a class can do, and with only a fraction of the overhead and better code readability.

That doesn't mean you shouldn't learn to understand classes though. If you're coding with others, people will use them all the time and you'll need to know how to juggle those classes. Writing your code to rely on functions means the code will be smaller, faster, and more readable. I've seen huge sites written using only functions that were snappy and quick, and I've seen tiny sites that had minimal functionality that relied heavily on classes and broke constantly. (When you have classes extending classes that contain classes as part of their classes, you know you've lost all semblance of easy maintainability.)

When it comes down to it, all data you're going to want to pass can easily be handled by the existing datatypes.

Classes were created as a mental crutch and provide no actual extra functionality, and the overly-complicated code they have a tendency to create defeats the point of that crutch in the long run.

in addition, you can drop multiple partitions from one statement (Dropping multiple partitions in Impala/Hive).

Extract from above link:

hive> alter table t drop if exists partition (p=1),partition (p=2),partition(p=3);
Dropped the partition p=1
Dropped the partition p=2
Dropped the partition p=3
OK

EDIT 1:

Also, you can drop bulk using a condition sign (>,<,<>), for example:

Alter table t 
drop partition (PART_COL>1);

Sometimes using libraries are cool when you do not want to reinvent the wheel, but in this case one can do the same job with fewer lines of code and easier to read compared to using libraries. Here is a different approach which I find very easy to use.

1. In this example, I use StreamReader to read the file
2. Regex to detect the delimiter from each line(s).
3. An array to collect the columns from index 0 to n

using (StreamReader reader = new StreamReader(fileName))
    {
        string line; 

        while ((line = reader.ReadLine()) != null)
        {
            //Define pattern
            Regex CSVParser = new Regex(",(?=(?:[^\"]*\"[^\"]*\")*(?![^\"]*\"))");

            //Separating columns to array
            string[] X = CSVParser.Split(line);

            /* Do something with X */
        }
    }

Dim myStringArray() As String
*code*
redim myStringArray(size_of_your_array)

Then you can do something static like this:

myStringArray = { item_1, item_2, ... }

Or something iterative like this:

Dim x
For x = 0 To size_of_your_array
    myStringArray(x) = data_source(x).Name
Next x

any large single block of data stored in a database, such as a picture or sound file, which does not include record fields, and cannot be directly searched by the database's search engine.

Thank you @Gorge Reith. Working off the solution provided by @George Reith, here is a function that furthers (1) separates out the individual 'hrefs' links (because they might be useful), (2) uses attributes as keys (since attributes are more descriptive), and (3) it's usable within Node.js without needing Chrome by using the 'jsdom' package:

const jsdom = require('jsdom') // npm install jsdom provides in-built Window.js without needing Chrome


// Function to map HTML DOM attributes to inner text and hrefs
function mapDOM(html_string, json) {
    treeObject = {}

    // IMPT: use jsdom because of in-built Window.js
    // DOMParser() does not provide client-side window for element access if coding in Nodejs
    dom = new jsdom.JSDOM(html_string)
    document = dom.window.document
    element = document.firstChild

    // Recursively loop through DOM elements and assign attributes to inner text object
    // Why attributes instead of elements? 1. attributes more descriptive, 2. usually important and lesser
    function treeHTML(element, object) {
        var nodeList = element.childNodes;
        if (nodeList != null) {
           if (nodeList.length) {
               object[element.nodeName] = []  // IMPT: empty [] array for non-text recursivable elements (see below)
               for (var i = 0; i < nodeList.length; i++) {
                   // if final text
                   if (nodeList[i].nodeType == 3) {
                       if (element.attributes != null) {
                           for (var j = 0; j < element.attributes.length; j++) {
                                if (element.attributes[j].nodeValue !== '' && 
                                    nodeList[i].nodeValue !== '') {
                                    if (element.attributes[j].name === 'href') { // separate href
                                        object[element.attributes[j].name] = element.attributes[j].nodeValue;
                                    } else {
                                        object[element.attributes[j].nodeValue] = nodeList[i].nodeValue;
                                    }

                                }
                           }
                       }
                   // else if non-text then recurse on recursivable elements
                   } else {
                       object[element.nodeName].push({}); // if non-text push {} into empty [] array
                       treeHTML(nodeList[i], object[element.nodeName][object[element.nodeName].length -1]);
                   }
               }
           }
        }
    }
    treeHTML(element, treeObject);

    return (json) ? JSON.stringify(treeObject) : treeObject;
}

A simple example in shell script

#!/bin/bash

current_date_time="`date +%Y%m%d%H%M%S`";
echo $current_date_time;

With out punctuation format :- +%Y%m%d%H%M%S
With punctuation :- +%Y-%m-%d %H:%M:%S

In case anyone is trying to apply the above solutions to a .scatter() instead of a .subplot(),

I tried running the following code

y = [2.56422, 3.77284, 3.52623, 3.51468, 3.02199]
z = [0.15, 0.3, 0.45, 0.6, 0.75]
n = [58, 651, 393, 203, 123]

fig, ax = plt.scatter(z, y)

for i, txt in enumerate(n):
    ax.annotate(txt, (z[i], y[i]))

But ran into errors stating "cannot unpack non-iterable PathCollection object", with the error specifically pointing at codeline fig, ax = plt.scatter(z, y)

I eventually solved the error using the following code

plt.scatter(z, y)

for i, txt in enumerate(n):
    plt.annotate(txt, (z[i], y[i]))

I didn't expect there to be a difference between .scatter() and .subplot() I should have known better.

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

This issue can also be caused by the cellular data of the device / emulator being turned off. Make sure you check that.

You should use TryParse method which Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the conversion succeeded.

    int intParsed;
    if(int.TryParse(txtMyText.Text.Trim(),out intParsed))
    {
        // perform your code
    }

* for python 2.x *

Use a trailing comma to avoid a newline.

print "Hey Guys!",
print "This is how we print on the same line."

The output for the above code snippet would be,

Hey Guys! This is how we print on the same line.

* for python 3.x *

for i in range(10):
    print(i, end="<separator>") # <separator> = \n, <space> etc.

The output for the above code snippet would be (when <separator> = " "),

0 1 2 3 4 5 6 7 8 9

The reason is that CTAS (Create table as select) does not copy any metadata from the source to the target table, namely

• no primary key
• no foreign keys
• no grants
• no indexes
• ...

To achieve what you want, I'd either

• use dbms_metadata.get_ddl to get the complete table structure, replace the table name with the new name, execute this statement, and do an INSERT afterward to copy the data
• or keep using CTAS, extract the not null constraints for the source table from user_constraints and add them to the target table afterwards

You could use this code.

public class MySampleActivity extends Activity {
    CheckBox cb1, cb2, cb3, cb4;
    LinearLayout l1, l2, l3, l4;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        cb1 = (CheckBox) findViewById(R.id.cb1);
        cb2 = (CheckBox) findViewById(R.id.cb2);
        cb3 = (CheckBox) findViewById(R.id.cb3);
        cb4 = (CheckBox) findViewById(R.id.cb4);
        l1 = (LinearLayout) findViewById(R.id.l1);
        l2 = (LinearLayout) findViewById(R.id.l2);
        l3 = (LinearLayout) findViewById(R.id.l3);
        l4 = (LinearLayout) findViewById(R.id.l4);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        cb1.setOnCheckedChangeListener(new MyCheckedChangeListener(1));
        cb1.setOnCheckedChangeListener(new MyCheckedChangeListener(2));
        cb1.setOnCheckedChangeListener(new MyCheckedChangeListener(3));
        cb1.setOnCheckedChangeListener(new MyCheckedChangeListener(4));
    }

    public class MyCheckedChangeListener implements CompoundButton.OnCheckedChangeListener {
        int position;

        public MyCheckedChangeListener(int position) {
            this.position = position;
        }

        private void changeVisibility(LinearLayout layout, boolean isChecked) {
            if (isChecked) {
                l1.setVisibility(View.VISIBLE);
            } else {
                l1.setVisibility(View.GONE);
            }

        }

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            switch (position) {
                case 1:
                    changeVisibility(l1, isChecked);
                    break;
                case 2:
                    changeVisibility(l2, isChecked);
                    break;
                case 3:
                    changeVisibility(l3, isChecked);
                    break;
                case 4:
                    changeVisibility(l4, isChecked);
                    break;
            }
        }
    }
}

I often use the following:

c := b
if a > b {
    c = a
}

basically the same as @Not_a_Golfer's but using type inference.

Update Since extract_numeric is deprecated, we can use parse_number from readr package.

library(readr)
parse_number(years)

Here is another option with extract_numeric

library(tidyr)
extract_numeric(years)
#[1] 20  1

I had the same problem and solved it like this:

final YourType[] yourArray = ...;
return new Iterable<YourType>() {
  public Iterator<YourType> iterator() {
     return Iterators.forArray(yourArray);   // Iterators is a Google guava utility
  }
}

The iterator itself is a lazy UnmodifiableIterator but that's exactly what I needed.

If you haven't committed the merge, then use:

git merge --abort

A procedure for dividing integers that uses shifts and adds can be derived in straightforward fashion from decimal longhand division as taught in elementary school. The selection of each quotient digit is simplified, as the digit is either 0 and 1: if the current remainder is greater than or equal to the divisor, the least significant bit of the partial quotient is 1.

Just as with decimal longhand division, the digits of the dividend are considered from most significant to least significant, one digit at a time. This is easily accomplished by a left shift in binary division. Also, quotient bits are gathered by left shifting the current quotient bits by one position, then appending the new quotient bit.

In a classical arrangement, these two left shifts are combined into left shifting of one register pair. The upper half holds the current remainder, the lower half initial holds the dividend. As the dividend bits are transferred to the remainder register by left shift, the unused least significant bits of the lower half are used to accumulate the quotient bits.

Below is x86 assembly language and C implementations of this algorithm. This particular variant of a shift & add division is sometimes referred to as the "no-performing" variant, as the subtraction of the divisor from the current remainder is not performed unless the remainder is greater than or equal to the divisor. In C, there is no notion of the carry flag used by the assembly version in the register pair left shift. Instead, it is emulated, based on the observation that the result of an addition modulo 2ⁿ can be smaller that either addend only if there was a carry out.

%d is for integers use %f instead, it works for both float and double types:

double d = 1.2;
float f = 1.2f;
System.out.printf("%f %f",d,f); // prints 1.200000 1.200000

I don't want to include the Support library just for getColor, so I'm using something like

public static int getColorWrapper(Context context, int id) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        return context.getColor(id);
    } else {
        //noinspection deprecation
        return context.getResources().getColor(id);
    }
}

I guess the code should work just fine, and the deprecated getColor cannot disappear from API < 23.

And this is what I'm using in Kotlin:

/**
 * Returns a color associated with a particular resource ID.
 *
 * Wrapper around the deprecated [Resources.getColor][android.content.res.Resources.getColor].
 */
@Suppress("DEPRECATION")
@ColorInt
fun getColorHelper(context: Context, @ColorRes id: Int) =
    if (Build.VERSION.SDK_INT >= 23) context.getColor(id) else context.resources.getColor(id);

Another way to continue with the example @nfreeze used is this validation method:

UserModel.schema.path('name').validate(function (value, res) {
    UserModel.findOne({name: value}, 'id', function(err, user) {
        if (err) return res(err);
        if (user) return res(false);
        res(true);
    });
}, 'already exists');

Pre C++11:

The function will not return the local variable, but rather a copy of it. Your compiler might however perform an optimization where no actual copy action is made.

See this question & answer for further details.

C++11:

The function will move the value. See this answer for further details.

According to the standard (§6.4.4.4/10)

The value of an integer character constant containing more than one character (e.g., 'ab'), [...] is implementation-defined.

long x = '\xde\xad\xbe\xef'; // yes, single quotes

This is valid ISO 9899:2011 C. It compiles without warning under gcc with -Wall, and a “multi-character character constant” warning with -pedantic.

From Wikipedia:

Multi-character constants (e.g. 'xy') are valid, although rarely useful — they let one store several characters in an integer (e.g. 4 ASCII characters can fit in a 32-bit integer, 8 in a 64-bit one). Since the order in which the characters are packed into one int is not specified, portable use of multi-character constants is difficult.

For portability sake, don't use multi-character constants with integral types.

Yes. add a linked server entry, and use select into using the four part db object naming convention.

Example:

SELECT * INTO targetTable 
FROM [sourceserver].[sourcedatabase].[dbo].[sourceTable]

If you want to set 777 permission to your created file than you can use the following method:

public void setPermission(File file) throws IOException{
    Set<PosixFilePermission> perms = new HashSet<>();
    perms.add(PosixFilePermission.OWNER_READ);
    perms.add(PosixFilePermission.OWNER_WRITE);
    perms.add(PosixFilePermission.OWNER_EXECUTE);

    perms.add(PosixFilePermission.OTHERS_READ);
    perms.add(PosixFilePermission.OTHERS_WRITE);
    perms.add(PosixFilePermission.OTHERS_EXECUTE);

    perms.add(PosixFilePermission.GROUP_READ);
    perms.add(PosixFilePermission.GROUP_WRITE);
    perms.add(PosixFilePermission.GROUP_EXECUTE);

    Files.setPosixFilePermissions(file.toPath(), perms);
}

You may have to run cmd as administrator to perform these tasks. You can do it by right clicking on cmd icon and selecting run as administrator. It's worked for me.

In my case, the solution was to remove the typeRoots in my tsconfig.json.

As you can read in the TypeScript doc

If typeRoots is specified, only packages under typeRoots will be included.

That would be the final solution. (inspired by @Hollan_Risley's post)

'use strict';

angular.module('app')

.config(function($provide) {
    $provide.decorator('$state', function($delegate, $stateParams) {
        $delegate.forceReload = function() {
            return $delegate.go($delegate.current, $stateParams, {
                reload: true,
                inherit: false,
                notify: true
            });
        };
        return $delegate;
    });
});

Now, whenever you need to reload, simply call:

$state.forceReload();

Any data type which is lower than "int" (except Boolean) is implicitly converts to "int".

In your case:

short a = 2;
short b = 3;
short c = a + b;

The result of (a+b) is implicitly converted to an int. And now you are assigning it to "short".So that you are getting the error.

short,byte,char --for all these we will get same error.

But why don't I have to install a certificate locally for the site?

Well the code that you are using is explicitly designed to accept the certificate without doing any checks whatsoever. This is not good practice ... but if that is what you want to do, then (obviously) there is no need to install a certificate that your code is explicitly ignoring.

Shouldn't I have to install a certificate locally and load it for this program or is it downloaded behind the covers?

No, and no. See above.

Is the traffic between the client to the remote site still encrypted in transmission?

Yes it is. However, the problem is that since you have told it to trust the server's certificate without doing any checks, you don't know if you are talking to the real server, or to some other site that is pretending to be the real server. Whether this is a problem depends on the circumstances.

If we used the browser as an example, typically a browser doesn't ask the user to explicitly install a certificate for each ssl site visited.

The browser has a set of trusted root certificates pre-installed. Most times, when you visit an "https" site, the browser can verify that the site's certificate is (ultimately, via the certificate chain) secured by one of those trusted certs. If the browser doesn't recognize the cert at the start of the chain as being a trusted cert (or if the certificates are out of date or otherwise invalid / inappropriate), then it will display a warning.

Java works the same way. The JVM's keystore has a set of trusted certificates, and the same process is used to check the certificate is secured by a trusted certificate.

Does the java https client api support some type of mechanism to download certificate information automatically?

No. Allowing applications to download certificates from random places, and install them (as trusted) in the system keystore would be a security hole.

This is a classic self-join, try the following:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e, emp m
WHERE e.mgr = m.empno

And if you want to include the president which has no manager then instead of an inner join use an outer join in Oracle syntax:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e, emp m
WHERE e.mgr = m.empno(+)

Or in ANSI SQL syntax:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e
    LEFT OUTER JOIN emp m
        ON e.mgr = m.empno

What's wrong with the standard stuff?

JSONObject jsonObject = new JSONObject(someJsonString);
JSONArray jsonArray = jsonObject.getJSONArray("someJsonArray");
String value = jsonArray.optJSONObject(i).getString("someJsonValue");

If you use a pem file to authenticate u can use the following command (which will exclude files with something extension):

rsync -Lavz -e "ssh -i <full-path-to-pem> -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" --exclude "*.something" --progress <path inside local host> <user>@<host>:<path inside remote host>

The -L means follow links (copy files not links). Use full path to your pem file and not relative.

Using sshfs is not recommended since it works slowly. Also, the combination of find and scp that was presented above is also a bad idea since it will open a ssh session per file which is too expensive.

Simply pass the sorted items from the dictionary to the plot() function. concentration.items() returns a list of tuples where each tuple contains a key from the dictionary and its corresponding value.

You can take advantage of list unpacking (with *) to pass the sorted data directly to zip, and then again to pass it into plot():

import matplotlib.pyplot as plt

concentration = {
    0: 0.19849878712984576,
    5000: 0.093917341754771386,
    10000: 0.075060643507712022,
    20000: 0.06673074282575861,
    30000: 0.057119318961966224,
    50000: 0.046134834546203485,
    100000: 0.032495766396631424,
    200000: 0.018536317451599615,
    500000: 0.0059499290585381479}

plt.plot(*zip(*sorted(concentration.items())))
plt.show()

sorted() sorts tuples in the order of the tuple's items so you don't need to specify a key function because the tuples returned by dict.item() already begin with the key value.

For what it's worth, here is how using GitHub on a Windows machine. Let's say you have a cloned repo in residing in C:\dir1. The directory structure looks like this: C:\dir1\dir2\dir3. The dir3 directory is the one I want to be a new separate repo.

Github:

1. Create your new repository: MyTeam/mynewrepo

Bash Prompt:

2. $ cd c:/Dir1

3. $ git filter-branch --prune-empty --subdirectory-filter dir2/dir3 HEAD
   Returned: Ref 'refs/heads/master' was rewritten (fyi: dir2/dir3 is case sensitive.)

4. $ git remote add some_name [email protected]:MyTeam/mynewrepo.git
git remote add origin etc. did not work, returned "remote origin already exists"

5. $ git push --progress some_name master

Now you can use insertOne method and in promise's result.insertedId

var1 is a regular string, whereas var2 is an array, this is how you should compare (in this case):

puts var1 == var2[0]

Your approach is decent for a folder that only contains files, but if you are looking for a scenario that also contains subfolders then recursion is needed

Also you should capture the return value of the return to make sure you are allowed to delete the file

and include

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

in your manifest

void DeleteRecursive(File dir)
{
    Log.d("DeleteRecursive", "DELETEPREVIOUS TOP" + dir.getPath());
    if (dir.isDirectory())
    {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++)
        {
            File temp = new File(dir, children[i]);
            if (temp.isDirectory())
            {
                Log.d("DeleteRecursive", "Recursive Call" + temp.getPath());
                DeleteRecursive(temp);
            }
            else
            {
                Log.d("DeleteRecursive", "Delete File" + temp.getPath());
                boolean b = temp.delete();
                if (b == false)
                {
                    Log.d("DeleteRecursive", "DELETE FAIL");
                }
            }
        }

    }
    dir.delete();
}

Open the SVG with you text editor. If you have some luck the file will contain something like:

The d attribute is what you are looking for.

For Using the_content() functions (for displaying the main content of the page)

$content = get_the_content();

echo substr($content, 0, 100);

For Using the_excerpt() functions (for displaying the excerpt-short content of the page)

$excerpt= get_the_excerpt();

echo substr($excerpt, 0, 100);

Store.getRange() seems to be exactly what you are searching for. It will return you Ext.data.Record[] - array of records. If no arguments is passed, all the records are returned.

If you want to calculate it yourself, then you can use the Haversine formula:

var rad = function(x) {
  return x * Math.PI / 180;
};

var getDistance = function(p1, p2) {
  var R = 6378137; // Earth’s mean radius in meter
  var dLat = rad(p2.lat() - p1.lat());
  var dLong = rad(p2.lng() - p1.lng());
  var a = Math.sin(dLat / 2) * Math.sin(dLat / 2) +
    Math.cos(rad(p1.lat())) * Math.cos(rad(p2.lat())) *
    Math.sin(dLong / 2) * Math.sin(dLong / 2);
  var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
  var d = R * c;
  return d; // returns the distance in meter
};

Please check that your form tag have this attribute:

This would eliminate the need for enumeration completely. You could change type to double if required.

Wrap it all up in an Async task to avoid threading errors.

You are probably looking for the DATEDIFF function.

DATEDIFF ( datepart , startdate , enddate )

Where you code might look like this:

DATEDIFF ( hh , startdate , enddate )

The worst way:

>>> def hex_to_int(x):
    return eval("0x" + x)

>>> hex_to_int("c0ffee")
12648430

Please don't do this!

Is using eval in Python a bad practice?

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd",Locale.getDefault());
Calendar calendar1 = Calendar.getInstance();
Calendar calendar2 = Calendar.getInstance();

Date date1 = dateFormat.parse("2013-01-01");
Date date2 = dateFormat.parse("2013-01-02");

calendar1.setTime(date1);
calendar2.setTime(date2);

System.out.println("Compare Result : " + calendar2.compareTo(calendar1));
System.out.println("Compare Result : " + calendar1.compareTo(calendar2));

Compares the time represented by this Calendar to that represented by the given Calendar.

Returns 0 if the times of the two Calendars are equal, -1 if the time of this Calendar is before the other one, 1 if the time of this Calendar is after the other one.

Another option is numpy.genfromtxt, e.g:

import numpy as np
data = np.genfromtxt("myfile.dat",delimiter=",")

This will make data a numpy array with as many rows and columns as are in your file

I know this is a pretty old topic but it might come in handy for anyone in the future. the script below does what the fella was trying to achieve purely using vbscript. when sorted terms starting in capital letters will have priority.

for a = UBound(ArrayOfTerms) - 1 To 0 Step -1
    for j= 0 to a
        if ArrayOfTerms(j)>ArrayOfTerms(j+1) then
            temp=ArrayOfTerms(j+1)
            ArrayOfTerms(j+1)=ArrayOfTerms(j)
            ArrayOfTerms(j)=temp
        end if
    next

In the current version of Sublime Text 2 (Build: 2139), you can set the syntax for all files of a certain file extension using an option in the menu bar. Open a file with the extension you want to set a default for and navigate through the following menus: View -> Syntax -> Open all with current extension as... ->[your syntax choice].

Updated 2012-06-28: Recent builds of Sublime Text 2 (at least since Build 2181) have allowed the syntax to be set by clicking the current syntax type in the lower right corner of the window. This will open the syntax selection menu with the option to Open all with current extension as... at the top of the menu.

Updated 2016-04-19: As of now, this also works for Sublime Text 3.

Use insert method from range, for example

Sub InsertColumn()
        Columns("C:C").Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
        Range("C1").Value = "Loc"
End Sub

<script src="//code.jquery.com/jquery.min.js"></script>
<script>
function changes() {
$('#link').val('new value');
}
</script>
<button onclick="changes()">a</button>
<input type='text' value='http://www.link.com' id='link'>

3306 is default port for mysql. Check it with:

it should give this result:

All boils down to if your server backend is timezone-agnostic or not. If it is not, then you need to assume that timezone of server is the same as client, or transfer information about client's timezone and include that also into calculations.

a PostgreSQL backend based example:

select '2009-09-28T08:00:00Z'::timestamp -> '2009-09-28 08:00:00' (wrong for 10am)
select '2009-09-28T08:00:00Z'::timestamptz -> '2009-09-28 10:00:00+02'
select '2009-09-28T08:00:00Z'::timestamptz::timestamp -> '2009-09-28 10:00:00'

The last one is probably what you want to use in database, if you are not willing properly implement timezone logic.

I am just re-posting the steps I used from msdn blog. It may help the community.

This will help you to setup a local web server known as lite-server with VS Code, and also guides you to host your static html files in localhost and debug your Javascript code.

1. Install Node.js

If not already installed, get it here

It comes with npm (the package manager for acquiring and managing your development libraries)

2. Create a new folder for your project

Somewhere in your drive, create a new folder for your web app.

3. Add a package.json file to the project folder

Then copy/paste the following text:

{
   "name": "Demo",
   "version": "1.0.0",
   "description": "demo project.",
   "scripts": {
     "lite": "lite-server --port 10001",
     "start": "npm run lite"
   },
   "author": "",
   "license": "ISC",
   "devDependencies": {
     "lite-server": "^2.5.4"
   }
}

4. Install the web server

In a terminal window (command prompt in Windows) opened on your project folder, run this command:

npm install

This will install lite-server (defined in package.json), a static server that loads index.html in your default browser and auto refreshes it when application files change.

5. Start the local web server!

(Assuming you have an index.html file in your project folder).

In the same terminal window (command prompt in Windows) run this command:

npm start

Wait a second and index.html is loaded and displayed in your default browser served by your local web server!

lite-server is watching your files and refreshes the page as soon as you make changes to any html, js or css files.

And if you have VS Code configured to auto save (menu File / Auto Save), you see changes in the browser as you type!

Notes:

• Do not close the command line prompt until you’re done coding in your app for the day
• It opens on http://localhost:10001 but you can change the port by editing the package.json file.

That’s it. Now before any coding session just type npm start and you are good to go!

Replace checked="checked" with checked={true}. Or you could even shorten it to just checked.

This is because the expected value type of the checked prop is a boolean. not a string.

In order to create an anonymous type (or any type) with a property that has a reserved keyword as its name in C#, you can prepend the property name with an at sign, @:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new { @class = "myclass"})

For VB.NET this syntax would be accomplished using the dot, ., which in that language is default syntax for all anonymous types:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new with { .class = "myclass" })

My recomendation is to keep the getRuntime().exec because exec uses the ProcessBuilder.

Try

 p=r.exec(new String[] {"winrar", "x", "h:\\myjar.jar", "*.*", "h:\\new"}, null, dir);

I have used

tabindex="{{isEditedParaOrder?-1:0}}" 
[style.pointer-events]="isEditedParaOrder ?'none':'auto'" 

in my anchor tag so that they can not move to anchor tag by using tab to use "enter" key and also pointer itself we are setting to 'none' based on property 'isEditedParaO rder' whi

Sure. On my (pretty vanilla) Cygwin setup, bash is in c:\cygwin\bin so I can run a bash script (say testit.sh) from a Windows batch file using a command like:

C:\cygwin\bin\bash testit.sh

... which can be included in a .bat file as easily as it can be typed at the command line, and with the same effect.

I. Plain XSLT 1.0 solution:

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()" name="split">
  <xsl:param name="pText" select="."/>
  <xsl:if test="string-length($pText)">
   <xsl:if test="not($pText=.)">
    <br />
   </xsl:if>
   <xsl:value-of select=
    "substring-before(concat($pText,';'),';')"/>
   <xsl:call-template name="split">
    <xsl:with-param name="pText" select=
     "substring-after($pText, ';')"/>
   </xsl:call-template>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

when applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

produces the wanted, corrected result:

123 Elm Street<br />PO Box 222<br />c/o James Jones

II. FXSL 1 (for XSLT 1.0):

Here we just use the FXSL template str-map (and do not have to write recursive template for the 999th time):

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:testmap="testmap"
exclude-result-prefixes="xsl f testmap"
>
   <xsl:import href="str-dvc-map.xsl"/>

   <testmap:testmap/>

   <xsl:output omit-xml-declaration="yes" indent="yes"/>

   <xsl:template match="/">
     <xsl:variable name="vTestMap" select="document('')/*/testmap:*[1]"/>
     <xsl:call-template name="str-map">
       <xsl:with-param name="pFun" select="$vTestMap"/>
       <xsl:with-param name="pStr" select=
       "'123 Elm Street;PO Box 222;c/o James Jones'"/>
     </xsl:call-template>
   </xsl:template>

    <xsl:template name="replace" mode="f:FXSL"
         match="*[namespace-uri() = 'testmap']">
      <xsl:param name="arg1"/>

      <xsl:choose>
       <xsl:when test="not($arg1=';')">
        <xsl:value-of select="$arg1"/>
       </xsl:when>
       <xsl:otherwise><br /></xsl:otherwise>
      </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

when this transformation is applied on any XML document (not used), the same, wanted correct result is produced:

123 Elm Street<br/>PO Box 222<br/>c/o James Jones

III. Using XSLT 2.0

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()">
  <xsl:for-each select="tokenize(.,';')">
   <xsl:sequence select="."/>
   <xsl:if test="not(position() eq last())"><br /></xsl:if>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

the wanted, correct result is produced:

123 Elm Street<br />PO Box 222<br />c/o James Jones

Once you've done this

group p by p.SomeId into pg  

you no longer have access to the range variables used in the initial from. That is, you can no longer talk about p or bp, you can only talk about pg.

Now, pg is a group and so contains more than one product. All the products in a given pg group have the same SomeId (since that's what you grouped by), but I don't know if that means they all have the same BaseProductId.

To get a base product name, you have to pick a particular product in the pg group (As you are doing with SomeId and CountryCode), and then join to BaseProducts.

var result = from p in Products                         
 group p by p.SomeId into pg                         
 // join *after* group
 join bp in BaseProducts on pg.FirstOrDefault().BaseProductId equals bp.Id         
 select new ProductPriceMinMax { 
       SomeId = pg.FirstOrDefault().SomeId, 
       CountryCode = pg.FirstOrDefault().CountryCode, 
       MinPrice = pg.Min(m => m.Price), 
       MaxPrice = pg.Max(m => m.Price),
       BaseProductName = bp.Name  // now there is a 'bp' in scope
 };

That said, this looks pretty unusual and I think you should step back and consider what you are actually trying to retrieve.

I was moving a folder up one level and into another folder. My mistake was doing the move from within the parent folder.

Bad example:

pwd -> C:\Repo\ParentDir\
svn move ./DirtoCopy ../AnotherDir

SVN needs to update the parent directory with the deleted folders info.
You have to do it from the common root of the source and destination folders or use full paths.

Good example:

svn move C:\Repo\ParentDir\DirtoCopy C:\Repo\NewLocation

Remove-Item -LiteralPath "foldertodelete" -Force -Recurse

REPEAT
    ...
UNTIL cond

Is equivalent to

while True:
    ...
    if cond:
        break
