Thanks for the great answers! Fastest way to get a few one-off files to Colab from Google drive: Load the Drive helper and mount

from google.colab import drive

This will prompt for authorization.

drive.mount('/content/drive')

Open the link in a new tab-> you will get a code - copy that back into the prompt you now have access to google drive check:

!ls "/content/drive/My Drive"

then copy file(s) as needed:

!cp "/content/drive/My Drive/xy.py" "xy.py"

confirm that files were copied:

!ls

First, the class must implements the click listenener :

implements OnItemClickListener

Then set a listener to the ListView

yourList.setOnItemclickListener(this);

And finally, create the clic method:

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(MainActivity.this, "You Clicked at " +countries[+ position], Toast.LENGTH_SHORT).show();
}

As @jwalkerjr mentioned, you should be disposing of connections in code (if connection pooling is enabled, they are just returned to the connection pool). The prescribed way to do this is using the 'using' statement:

// Execute stored proc to read data from repository
using (SqlConnection conn = new SqlConnection(this.connectionString))
{
    using (SqlCommand cmd = conn.CreateCommand())
    {
        cmd.CommandText = "LoadFromRepository";
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@ID", fileID);

        conn.Open();
        using (SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection))
        {
            if (rdr.Read())
            {
                filename = SaveToFileSystem(rdr, folderfilepath);
            }
        }
    }
}

I'm sorry to do this, but I couldn't use any of the other answers as-is and haven't time to duke it out in the comments.

Uses C# 6 syntax.

static class EnumExtensions
{
    /// returns the localized Name, if a [Display(Name="Localised Name")] attribute is applied to the enum member
    /// returns null if there isnt an attribute
    public static string DisplayNameOrEnumName(this Enum value)
    // => value.DisplayNameOrDefault() ?? value.ToString()
    {
        // More efficient form of ^ based on http://stackoverflow.com/a/17034624/11635
        var enumType = value.GetType();
        var enumMemberName = Enum.GetName(enumType, value);
        return enumType
            .GetEnumMemberAttribute<DisplayAttribute>(enumMemberName)
            ?.GetName() // Potentially localized
            ?? enumMemberName; // Or fall back to the enum name
    }

    /// returns the localized Name, if a [Display] attribute is applied to the enum member
    /// returns null if there is no attribute
    public static string DisplayNameOrDefault(this Enum value) =>
        value.GetEnumMemberAttribute<DisplayAttribute>()?.GetName();

    static TAttribute GetEnumMemberAttribute<TAttribute>(this Enum value) where TAttribute : Attribute =>
        value.GetType().GetEnumMemberAttribute<TAttribute>(value.ToString());

    static TAttribute GetEnumMemberAttribute<TAttribute>(this Type enumType, string enumMemberName) where TAttribute : Attribute =>
        enumType.GetMember(enumMemberName).Single().GetCustomAttribute<TAttribute>();
}

While you should ideally highlight the code which is causing an error and post that within your question, the error is because you are trying to get the inner HTML of the 'status' element:

var idPost=document.getElementById("status").innerHTML;

However the 'status' element does not exist within your HTML - either add the necessary element or change the ID you are trying to locate to point to a valid element.

this is an out of topic answer, but, for those who are interested, it maybe valuable.

As in @John Kugelman's answer, % is related to job specification. how to efficiently find that? use less's &pattern command, seems man use less pager (not that sure), in man bash type &% then type Enter will only show lines that containing '%', to reshow all, type &. then Enter.

This builds on ntc2 and Chris Johnsen's answer. I am using this whenever I want to create a new session with a custom history-limit. I wanted a way to create sessions with limited scrollback without permanently changing my history-limit for future sessions.

tmux set-option -g history-limit 100 \; new-session -s mysessionname \; set-option -g history-limit 2000

This works whether or not there are existing sessions. After setting history-limit for the new session it resets it back to the default which for me is 2000.

I created an executable bash script that makes this a little more useful. The 1st parameter passed to the script sets the history-limit for the new session and the 2nd parameter sets its session name:

#!/bin/bash
tmux set-option -g history-limit "${1}" \; new-session -s "${2}" \; set-option -g history-limit 2000

I think you have to store the number on heap. The int ret variable was on stack and was destructed at the end of execution of function myThread.

void *myThread()
{
       int *ret = malloc(sizeof(int));
       if (ret == NULL) {
           // ...
       }
       *ret = 42;
       pthread_exit(ret);
}

Don't forget to free it when you don't need it :)

Another solution is to return the number as value of the pointer, like Neil Butterworth suggests.

Might be late to answer - if you don't want to modify your current code a lot and still be able to have similar validation code all over your project, you may try this one too - https://github.com/vishalvisd/react-validator.

The cleanest way in modern Python >=3.6, is to use an f-string with string formatting:

>>> var = 1.6
>>> f"{var:.15f}"
'1.600000000000000'

$prefix = '_';
$arr = array_combine(
    array_map(function($v) use ($prefix){
       return $prefix.$v;
    }, array_keys($arr)),
    array_values($arr)
);

You have two ways to do that:

METHOD 1. The secure way.

Put the images on /www/htdocs/

<?php
    $www_root = 'http://localhost/images';
    $dir = '/var/www/images';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if ( file_exists( $dir ) == false ) {
       echo 'Directory \'', $dir, '\' not found!';
    } else {
       $dir_contents = scandir( $dir );

        foreach ( $dir_contents as $file ) {
           $file_type = strtolower( end( explode('.', $file ) ) );
           if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
              echo '<img src="', $www_root, '/', $file, '" alt="', $file, '"/>';
           break;
           }
        }
    }
?>

METHOD 2. Unsecure but more flexible.

Put the images on any directory (apache must have permission to read the file).

<?php
    $dir = '/home/user/Pictures';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if ( file_exists( $dir ) == false ) {
       echo 'Directory \'', $dir, '\' not found!';
    } else {
       $dir_contents = scandir( $dir );

        foreach ( $dir_contents as $file ) {
           $file_type = strtolower( end( explode('.', $file ) ) );
           if ( ($file !== '.') && ($file !== '..') && (in_array( $file_type, $file_display)) ) {
              echo '<img src="file_viewer.php?file=', base64_encode($dir . '/' . $file), '" alt="', $file, '"/>';
           break;
           }
        }
    }
?>

And create another script to read the image file.

<?php
    $filename = base64_decode($_GET['file']);
    // Check the folder location to avoid exploit
    if (dirname($filename) == '/home/user/Pictures')
        echo file_get_contents($filename);
?>

This is a good question.

All your question is based on "how do we represent a number?"

ALL the numbers can be represented with decimal representation or with binary (2's complement) representation. All of them !!

BUT some (most of them) require infinite number of elements ("0" or "1" for the binary position, or "0", "1" to "9" for the decimal representation).

Like 1/3 in decimal representation (1/3 = 0.3333333... <- with an infinite number of "3")

Like 0.1 in binary ( 0.1 = 0.00011001100110011.... <- with an infinite number of "0011")

Everything is in that concept. Since your computer can only consider finite set of digits (decimal or binary), only some numbers can be exactly represented in your computer...

And as said Jon, 3 is a prime number which isn't a factor of 10, so 1/3 cannot be represented with a finite number of elements in base 10.

Even with arithmetic with arbitrary precision, the numbering position system in base 2 is not able to fully describe 6.1, although it can represent 61.

For 6.1, we must use another representation (like decimal representation, or IEEE 854 that allows base 2 or base 10 for the representation of floating-point values)

You could use numpy.fromfile, which can read data from both text and binary files. You would first construct a data type, which represents your file format, using numpy.dtype, and then read this type from file using numpy.fromfile.

The first suggestion in latkin's answer seems good, although I would suggest the less long-winded way below.

PS c:\temp> $global:test="one"

PS c:\temp> $test
one

PS c:\temp> function changet() {$global:test="two"}

PS c:\temp> changet

PS c:\temp> $test
two

His second suggestion however about being bad programming practice, is fair enough in a simple computation like this one, but what if you want to return a more complicated output from your variable? For example, what if you wanted the function to return an array or an object? That's where, for me, PowerShell functions seem to fail woefully. Meaning you have no choice other than to pass it back from the function using a global variable. For example:

PS c:\temp> function changet([byte]$a,[byte]$b,[byte]$c) {$global:test=@(($a+$b),$c,($a+$c))}

PS c:\temp> changet 1 2 3

PS c:\temp> $test
3
3
4

PS C:\nb> $test[2]
4

I know this might feel like a bit of a digression, but I feel in order to answer the original question we need to establish whether global variables are bad programming practice and whether, in more complex functions, there is a better way. (If there is one I'd be interested to here it.)

Here is an example of using Bootstrap's Button via React-Bootstrap (version 0.32.4):

var condition = true;

return (
  <Button {...(condition ? {bsStyle: 'success'} : {})} />
);

Depending on the condition, either {bsStyle: 'success'} or {} will be returned. The spread operator will then spread the properties of the returned object to Button component. In the falsy case, since no properties exist on the returned object, nothing will be passed to the component.

An alternative way based on Andy Polhill's comment:

var condition = true;

return (
  <Button bsStyle={condition ? 'success' : undefined} />
);

The only small difference is that in the second example the inner component <Button/>'s props object will have a key bsStyle with a value of undefined.

For me there was was quite a simple solution. I was trying to edit/create a file in a folder that didn't exist. As I was already in the folder I was trying to edit/create a file in.

i.e. pwd folder/file

and was typing

sudo vim folder/file

and rather obviously it was looking for the folder in the folder and failing to save.

I would wrap the text in a so you can target it separately. Now if you float both and left, you can use line-height to control the vertical spacing of the . Setting it to the same height as the (30px) will middle align it. See here.

New Markup:

 <div>
    <i class='icon icon-2x icon-camera'></i>
    <span id="text">hello world</span>
</div>

New CSS:

div {
    border: 1px solid #ccc;
    height: 30px;
    margin: 60px;
    padding: 4px;
    vertical-align: middle;
}
i{
    float: left;
}
#text{
    line-height: 30px;
    float: left;
}

The identity (===) operator behaves identically to the equality (==) operator except no type conversion is done, and the types must be the same to be considered equal.

This issue came for me due to the fact that .. i was running server with selenium-server-standalone-2.32.0 and client registered with selenium-server-standalone-2.37.0 .. When i made both selenium-server-standalone-2.32.0 and ran then things worked fine

Use "content:;" at the hover.This works.

If you need a floating random number between 13 and 20

(20-13).*rand(1) + 13

If you need an integer random number between 13 and 20

floor((21-13).*rand(1) + 13)

Note: Fix problem mentioned in comment "This excludes 20" by replacing 20 with 21

Check out this metadata extractor. It is written in Java but has also been ported to C#. I have used the Java version to write a small utility to rename my jpeg files based on the date and model tags. Very easy to use.

EDIT metadata-extractor supports .NET too. It's a very fast and simple library for accessing metadata from images and videos.

It fully supports Exif, as well as IPTC, XMP and many other types of metadata from file types including JPEG, PNG, GIF, PNG, ICO, WebP, PSD, ...

var directories = ImageMetadataReader.ReadMetadata(imagePath);

// print out all metadata
foreach (var directory in directories)
foreach (var tag in directory.Tags)
    Console.WriteLine($"{directory.Name} - {tag.Name} = {tag.Description}");

// access the date time
var subIfdDirectory = directories.OfType<ExifSubIfdDirectory>().FirstOrDefault();
var dateTime = subIfdDirectory?.GetDateTime(ExifDirectoryBase.TagDateTime);

It's available via NuGet and the code's on GitHub.

Bus errors are rare nowadays on x86 and occur when your processor cannot even attempt the memory access requested, typically:

• using a processor instruction with an address that does not satisfy its alignment requirements.

Segmentation faults occur when accessing memory which does not belong to your process, they are very common and are typically the result of:

• using a pointer to something that was deallocated.
• using an uninitialized hence bogus pointer.
• using a null pointer.
• overflowing a buffer.

PS: To be more precise this is not manipulating the pointer itself that will cause issues, it's accessing the memory it points to (dereferencing).

You should avoid hardcoding SQL statements in your application. If you don't use ADO nor EntityFramework, I would suggest you to ad a stored procedure to the database and call it from your c# application. A sample code can be found here: How to execute a stored procedure within C# program and here http://msdn.microsoft.com/en-us/library/ms171921%28v=vs.80%29.aspx.

Since neither of the above worked for me, here's what did: android:scrollbarDefaultDelayBeforeFade="500000"

An example where things could go wrong with Shell=True is shown here

>>> from subprocess import call
>>> filename = input("What file would you like to display?\n")
What file would you like to display?
non_existent; rm -rf / # THIS WILL DELETE EVERYTHING IN ROOT PARTITION!!!
>>> call("cat " + filename, shell=True) # Uh-oh. This will end badly...

Check the doc here: subprocess.call()

As of end of 2020 and Python 3.8.5 on linux console for me only this works:

print('some string', end='\r')

If the HTML is not XML you can't do it with etree. But even then, you don't have to use an external library for parsing a HTML table. In python 3 you can reach your goal with HTMLParser from html.parser. I've the code of the simple derived HTMLParser class here in a github repo.

You can use that class (here named HTMLTableParser) the following way:

import urllib.request
from html_table_parser import HTMLTableParser

target = 'http://www.twitter.com'

# get website content
req = urllib.request.Request(url=target)
f = urllib.request.urlopen(req)
xhtml = f.read().decode('utf-8')

# instantiate the parser and feed it
p = HTMLTableParser()
p.feed(xhtml)
print(p.tables)

The output of this is a list of 2D-lists representing tables. It looks maybe like this:

[[['   ', ' Anmelden ']],
 [['Land', 'Code', 'Für Kunden von'],
  ['Vereinigte Staaten', '40404', '(beliebig)'],
  ['Kanada', '21212', '(beliebig)'],
  ...
  ['3424486444', 'Vodafone'],
  ['  Zeige SMS-Kurzwahlen für andere Länder ']]]

I had the same problem. Just after enabling Internet Virtualization from BIOS. After that let the system boot and install HAXM once again. Now emulator will run faster than before and HAXM will work. Enjoy!!

I usually find that ProgrammableWeb is a good place to go when looking for APIs.

In Swift, you can overload existing operators:

func > (lhs: NSDate, rhs: NSDate) -> Bool {
    return lhs.timeIntervalSinceReferenceDate > rhs.timeIntervalSinceReferenceDate
}

func < (lhs: NSDate, rhs: NSDate) -> Bool {
    return lhs.timeIntervalSinceReferenceDate < rhs.timeIntervalSinceReferenceDate
}

Then, you can compare NSDates directly with <, >, and == (already supported).

The SDK agreement and App store guidelines have been changed (circa Sept 2010).

You can now probably use any compiled language that will compile to the same static ARM object file format as Xcode produces and that will link to (only) the public API's within Apple's frameworks and libraries. However, you can not use a JIT compiled language unless you pre-compile all object code before submission to Apple for review.

You can use any interpreted language, as long as you embed the interpreter, and do not allow the interpreter or the app to download and run any interpretable code other than code built into the app bundle before submission to Apple for review, or source code typed-in by the user.

Objective C and C will likely still be the most optimal programming language for anything requiring high performance and the latest API support (* see update below), as those are the languages for which Apple targets its iOS frameworks and tunes its ARM processor chipsets. Apple also supports the use of Javascript/HTML5 inside a UIWebView. Those are the only languages for which Apple has announced support. Anything else you will have to find support elsewhere.

But, if you really want, there are at least a half dozen BASIC interpreters now available in the iOS App store, so even "Stone Age" programming methodology is now allowed.

Added: (*) As of late 2014, one can also develop apps using Apple's new Swift programming language. As of early 2015, submitted binaries must include 64-bit (arm64) support.

Consider a solution that will neatly handle arbitrarily many tables.

//ASSUMPTION: All tables must have the same columns
var tables = new List<DataTable>();
tables.Add(oneTableToRuleThemAll);
tables.Add(oneTableToFindThem);
tables.Add(oneTableToBringThemAll);
tables.Add(andInTheDarknessBindThem);
//Or in the real world, you might be getting a collection of tables from some abstracted data source.

//behold, a table too great and terrible to imagine
var theOneTable = tables.SelectMany(dt => dt.AsEnumerable()).CopyToDataTable();

Encapsulated into a helper for future reuse:

public static DataTable CombineDataTables(params DataTable[] args)
{
    return args.SelectMany(dt => dt.AsEnumerable()).CopyToDataTable();
}

Just have a few tables declared in code?

var combined = CombineDataTables(dt1,dt2,dt3);

Want to combine into one of the existing tables instead of creating a new one?

dt1 = CombineDataTables(dt1,dt2,dt3);

Already have a collection of tables, instead of declared one by one?

//Pretend variable tables already exists
var tables = new[] { dt1, dt2, dt3 };
var combined = CombineDataTables(tables);

You can use the gradle argument --project-cache-dir "/Users/whatever/.gradle/" to force the gradle cache directory.

In this way you can be darn sure you know what directory is being used (as well as create different caches for different projects)

The actual information represented by a boolean value in Java is one bit: 1 for true, 0 for false. However, the actual size of a boolean variable in memory is not precisely defined by the Java specification. See Primitive Data Types in Java.

The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. This data type represents one bit of information, but its "size" isn't something that's precisely defined.

Here I found a solution by comparing buttons in a button-group element. The simple solution is to get the one with the largest width and set the width to the other buttons. So they can have a equal width.

    function EqualizeButtons(parentElementId) {

    var longest = 0; 
    var element = $(parentElementId);

    element.find(".btn:not(.button-controlled)").each(function () {
        $(this).addClass('button-controlled');
        var width = $(this).width();
        if (longest < width) longest = width;

    }).promise().done(function () {
        $('.button-controlled').width(longest);
    });
}

It worked like a charm.

try: $(".highlight").removeClass("highlight");. By selecting $(".edgetoedge") you are only running functions at that level.

You can do

orig.update(extra)

or, if you don't want orig to be modified, make a copy first:

dest = dict(orig)  # or orig.copy()
dest.update(extra)

Note that if extra and orig have overlapping keys, the final value will be taken from extra. For example,

>>> d1 = {1: 1, 2: 2}
>>> d2 = {2: 'ha!', 3: 3}
>>> d1.update(d2)
>>> d1
{1: 1, 2: 'ha!', 3: 3}

Dim have had different meanings attributed to it.

I've found references about Dim meaning "Declare In Memory", the more relevant reference is a document on Dim Statement published Oracle as part of the Siebel VB Language Reference. Of course, you may argue that if you do not declare the variables in memory where do you do it? Maybe "Declare in Module" is a good alternative considering how Dim is used.

In my opinion, "Declare In Memory" is actually a mnemonic, created to make easier to learn how to use Dim. I see "Declare in Memory" as a better meaning as it describes what it does in current versions of the language, but it is not the proper meaning.

In fact, at the origins of Basic Dim was only used to declare arrays. For regular variables no keyword was used, instead their type was inferred from their name. For instance, if the name of the variable ends with $ then it is a string (this is something that you could see even in method names up to VB6, for example Mid$). And so, you used Dim only to give dimension to the arrays (notice that ReDim resizes arrays).

Really, Does It Matter? I mean, it is a keyword it has its meaning inside an artificial language. It doesn't have to be a word in English or any other natural language. So it could just mean whatever you want, all that matters is that it works.

Anyhow, that is not completely true. As BASIC is part of our culture, and understanding why it came to be as it is - I hope - will help improve our vision of the world.

I sit in from of my computer with a desire to help preserve this little piece of our culture that seems lost, replaced by our guessing of what it was. And so, I have dug MSDN both current and the old CDs from the 1998 version. I have also searched the documention for the old QBasic [Had to use DOSBox] and managed to get some Darthmouth manual, all to find how they talk about Dim. For my disappointment, they don't say what does Dim stand for, and only say how it is used.

But before my hope was dim, I managed to find this BBC Microcomputer System Used Guide (that claims to be from 1984, and I don't want to doubt it). The BBC Microcomputer used a variant of BASIC called BBC BASIC and it is described in the document. Even though, it doesn't say what does Dim stand for, it says (on page 104):

... you can dimension N$ to have as many entries as you want. For example, DIM N$(1000) would create a string array with space for 1000 different names.

As I said, it doesn't say that Dim stands for dimension, but serves as proof to show that associating Dim with Dimension was a common thing at the time of writing that document.

Now, I got a rewarding surprise later on (at page 208), the title for the section that describes the DIM keyword (note: that is not listed in the contents) says:

DIM dimension of an array

So, I didn't get the quote "Dim stands for..." but I guess it is clear that any decent human being that is able to read those document will consider that Dim means dimension.

With renewed hope, I decided to search about how Dim was chosen. Again, I didn't find an account on the subject, still I was able to find a definitive quote:

Before you can use an array, you must define it in a DIM (dimension) statement.

You can find this as part of the True BASIC Online User's Guides at the web page of True BASIC inc, a company founded by Thomas Eugene Kurtz, co-author of BASIC.

So, In reallity, Dim is a shorthand for DIMENSION, and yes. That existed in FORTRAN before, so it is likely that it was picked by influence of FORTRAN as Patrick McDonald said in his answer.

Dim sum as string = "this is not a chinese meal" REM example usage in VB.NET ;)

Put the Text in a Center:

Container(
      height: 45,
      color: Colors.black,
      child: Center(
        child: Text(
            'test',
            style: TextStyle(color: Colors.white),
        ),
      ),
    );

Same situation: Having done multiple Angular projects and moving to React, not having a simple way to provide services through DI seems like a missing piece (the particulars of the service aside).

Using context and ES7 decorators we can come close:

https://jaysoo.ca/2015/06/09/react-contexts-and-dependency-injection/

Seems these guys have taken it a step further / in a different direction:

http://blog.wolksoftware.com/dependency-injection-in-react-powered-inversifyjs

Still feels like working against the grain. Will revisit this answer in 6 months time after undertaking a major React project.

EDIT: Back 6 months later with some more React experience. Consider the nature of the logic:

1. Is it tied (only) to UI? Move it into a component (accepted answer).
2. Is it tied (only) to state management? Move it into a thunk.
3. Tied to both? Move to separate file, consume in component through a selector and in thunks.

Some also reach for HOCs for reuse but for me the above covers almost all use cases. Also, consider scaling state management using ducks to keep concerns separate and state UI-centric.

This worked form me.. PHP Code on page.php

 $query_de="sql statements here";
 $sql_de = sqlsrv_query($conn,$query_de);
      if ($sql_de)
      {
        echo "SQLSuccess";
       }
         exit();

and then AJAX Code has bellow

jQuery.ajax({
                    url  : "page.php",
                    type : "POST",
                    data : {
                            buttonsave   : 1,

                              },
                  success:function(data)
                           {
                     if(jQuery.trim(data) === "SQLSuccess")
                                   {
                           alert("Se agrego correctamente");
                          // alert(data);
                                      } else { alert(data);}
                              },
                   error: function(error)
                           {
                    alert("Error AJAX not working: "+ error );
                              } 
               }); 

NOTE: the word 'SQLSuccess' must be received from PHP

You might want to start with an introduction to version control. This guide is specific to subversion, but the core concepts can be applied to most version control systems. After you have the basics, you can delve into the git guide.

You can use distutils.dir_util.copy_tree. It works just fine and you don't have to pass every argument, only src and dst are mandatory.

However in your case you can't use a similar tool likeshutil.copytree because it behaves differently: as the destination directory must not exist this function can't be used for overwriting its contents.

If you want to use the cp tool as suggested in the question comments beware that using the subprocess module is currently the recommended way for spawning new processes as you can see in the documentation of the os.system function.

To my knowledge, there is sadly no CSS filter to colorise an element (perhaps with the use of some SVG filter magic, but I'm somewhat unfamiliar with that) and even if that wasn't the case, filters are basically only supported by webkit browsers.

With that said, you could still work around this and use a canvas to modify your image. Basically, you can draw an image element onto a canvas and then loop through the pixels, modifying the respective RGBA values to the colour you want.

However, canvases do come with some restrictions. Most importantly, you have to make sure that the image src comes from the same domain as the page. Otherwise the browser won't allow you to read or modify the pixel data of the canvas.

Here's a JSFiddle changing the colour of the JSFiddle logo.

You can try this script in the header of HTML code:

<script>
   $.extend(  $.mobile , {
   ajaxEnabled: false,
   hashListeningEnabled: false
   });
</script>

Syntax is source <file-name>

ex. source config.sh

script - config.sh

USERNAME="satish"
EMAIL="[email protected]"

calling script -

#!/bin/bash
source config.sh
echo Welcome ${USERNAME}!
echo Your email is ${EMAIL}.

You can learn to include a bash script in another bash script here.

In my case this problem happened after my windows 10 updated to the latest version

-I have tried most of above solutions but not helped me

-I also checked event viewer to see what error happened.

this is the error related to iis was happened but not found any solution on internet about it after a lot of search

The Module DLL 'C:\WINDOWS\System32\inetsrv\cgi.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture. The data field contains the error number. To learn more about this issue, including how to troubleshooting this kind of processor architecture mismatch error, see http://go.microsoft.com/fwlink/?LinkId=29349.

The way i solve this problem is changing Enable 32-Bit Applications value to True

by right clicking on DefaultAppPool in IIS Manager and select Advanced Settings

The possible reason can also be that you have not inherited Controller from ApiController. Happened with me took a while to understand the same.

You can also try:

function getTagValue($string, $tag)
{
    $pattern = "/<{$tag}>(.*?)<\/{$tag}>/s";
    preg_match($pattern, $string, $matches);
    return isset($matches[1]) ? $matches[1] : '';
}

It returns empty string in case of no match.

It means that you have to have PHP installed as a module in Apache, instead of starting it as a CGI script.

If a variable is not set then it is NULL and if you try to divide something by null you will get a divides by zero error

In windows You may try this batch file to help you to shuffle your data.txt, The usage of the batch code is

C:\> type list.txt | shuffle.bat > maclist_temp.txt

After issuing this command, maclist_temp.txt will contain a randomized list of lines.

Hope this helps.

Pandas timestamp differences returns a datetime.timedelta object. This can easily be converted into hours by using the *as_type* method, like so

import pandas
df = pandas.DataFrame(columns=['to','fr','ans'])
df.to = [pandas.Timestamp('2014-01-24 13:03:12.050000'), pandas.Timestamp('2014-01-27 11:57:18.240000'), pandas.Timestamp('2014-01-23 10:07:47.660000')]
df.fr = [pandas.Timestamp('2014-01-26 23:41:21.870000'), pandas.Timestamp('2014-01-27 15:38:22.540000'), pandas.Timestamp('2014-01-23 18:50:41.420000')]
(df.fr-df.to).astype('timedelta64[h]')

to yield,

0    58
1     3
2     8
dtype: float64

Depending on the file type you are focused on, Ctrl+H will open up different types of search screens.

A more consistent hotkey would be using the Alt method: Tap Alt, then A, then F.

Efficient Order of Operations:

1. Ctrl+C the text you want to do the replacing (if available)
2. Highlight the text you want to be replaced
3. Tap ALT, then A, then F. Brings you to File Search. The selection from (2) will auto-fill the search box
4. In the “File name patterns” input box, type in “.java” for replacing all Java files or type in "" to replace in all files
5. Click “Replace…”
6. Ctrl+V (Paste). Or type in the value you want to do the replacing
7. Enter

You can find more details in my blog post: http://blog.simplyadvanced.net/android-how-to-findreplace-in-multiple-files-using-eclipse/

You can use string.Format:

string template = "Hi We have these flights for you: {0}. Which one do you want";
string data = "A, B, C, D";
string message = string.Format(template, data);

You should load template from your resource file and data is your runtime values.

Be careful if you're translating to multiple languages, though: in some cases, you'll need different tokens (the {0}) in different languages.

You can also run ->select('DISTINCT `field`', FALSE) and the second parameter tells CI not to escape the first argument.

With the second parameter as false, the output would be SELECT DISTINCT `field` instead of without the second parameter, SELECT `DISTINCT` `field`

Other answers have already explained why virtual function calls don't work as expected when called from a constructor. I'd like to instead propose another possible work around for getting polymorphic-like behavior from a base type's constructor.

By adding a template constructor to the base type such that the template argument is always deduced to be the derived type it's possible to be aware of the derived type's concrete type. From there, you can call static member functions for that derived type.

This solution does not allow non-static member functions to be called. While execution is in the base type's constructor, the derived type's constructor hasn't even had time to go through it's member initialization list. The derived type portion of the instance being created hasn't begun being initialized it. And since non-static member functions almost certainly interact with data members it would be unusual to want to call the derived type's non-static member functions from the base type's constructor.

Here is a sample implementation :

#include <iostream>
#include <string>

struct Base {
protected:
    template<class T>
    explicit Base(const T*) : class_name(T::Name())
    {
        std::cout << class_name << " created\n";
    }

public:
    Base() : class_name(Name())
    {
        std::cout << class_name << " created\n";
    }


    virtual ~Base() {
        std::cout << class_name << " destroyed\n";
    }

    static std::string Name() {
        return "Base";
    }

private:
    std::string class_name;
};


struct Derived : public Base
{   
    Derived() : Base(this) {} // `this` is used to allow Base::Base<T> to deduce T

    static std::string Name() {
        return "Derived";
    }
};

int main(int argc, const char *argv[]) {

    Derived{};  // Create and destroy a Derived
    Base{};     // Create and destroy a Base

    return 0;
}

This example should print

Derived created
Derived destroyed
Base created
Base destroyed

When a Derived is constructed, the Base constructor's behavior depends on the actual dynamic type of the object being constructed.

The above answer doesn't work. You have to set DeliveryMethod = SmtpDeliveryMethod.Network or it will come back with a "client was not authenticated" error. Also it's always a good idea to put a timeout.

Revised code:

using System.Net.Mail;
using System.Net;

var fromAddress = new MailAddress("[email protected]", "From Name");
var toAddress = new MailAddress("[email protected]", "To Name");
const string fromPassword = "password";
const string subject = "test";
const string body = "Hey now!!";

var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
    Timeout = 20000
};
using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body
})
{
    smtp.Send(message);
}

Pim's answer is very helpful. In my case, I have to use

Expires / Max-Age: "Session"

If it is a dateTime, even it is not expired, it still won't send the cookie to the backend:

Expires / Max-Age: "Thu, 21 May 2020 09:00:34 GMT"

Hope it is helpful for future people who may meet same issue.

You can achieve this by using a span and a textarea.

You have to update the span with the text in textarea each time the text is changed. Then set the css width and height of the textarea to the span's clientWidth and clientHeight property.

Eg:

.textArea {
    border: #a9a9a9 1px solid;
    overflow: hidden;
    width:  expression( document.getElementById("spnHidden").clientWidth );
    height: expression( document.getElementById("spnHidden").clientHeight );
}

Is it "safe" to use $_SERVER['HTTP_HOST'] for all links on a site without having to worry about XSS attacks, even when used in forms?

Yes, it's safe to use $_SERVER['HTTP_HOST'], (and even $_GET and $_POST) as long as you verify them before accepting them. This is what I do for secure production servers:

/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
$reject_request = true;
if(array_key_exists('HTTP_HOST', $_SERVER)){
    $host_name = $_SERVER['HTTP_HOST'];
    // [ need to cater for `host:port` since some "buggy" SAPI(s) have been known to return the port too, see http://goo.gl/bFrbCO
    $strpos = strpos($host_name, ':');
    if($strpos !== false){
        $host_name = substr($host_name, $strpos);
    }
    // ]
    // [ for dynamic verification, replace this chunk with db/file/curl queries
    $reject_request = !array_key_exists($host_name, array(
        'a.com' => null,
        'a.a.com' => null,
        'b.com' => null,
        'b.b.com' => null
    ));
    // ]
}
if($reject_request){
    // log errors
    // display errors (optional)
    exit;
}
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
echo 'Hello World!';
// ...

The advantage of $_SERVER['HTTP_HOST'] is that its behavior is more well-defined than $_SERVER['SERVER_NAME']. Contrast ??:

Contents of the Host: header from the current request, if there is one.

with:

The name of the server host under which the current script is executing.

Using a better defined interface like $_SERVER['HTTP_HOST'] means that more SAPIs will implement it using reliable well-defined behavior. (Unlike the other.) However, it is still totally SAPI dependent ??:

There is no guarantee that every web server will provide any of these [$_SERVER entries]; servers may omit some, or provide others not listed here.

To understand how to properly retrieve the host name, first and foremost you need to understand that a server which contains only code has no means of knowing (pre-requisite for verifying) its own name on the network. It needs to interface with a component that supplies it its own name. This can be done via:

• local config file

• local database

• hardcoded source code

• external request (curl)

• client/attacker's Host: request

• etc

Usually its done via the local (SAPI) config file. Note that you have configured it correctly, e.g. in Apache ??:

A couple of things need to be 'faked' to make the dynamic virtual host look like a normal one.

The most important is the server name which is used by Apache to generate self-referential URLs, etc. It is configured with the ServerName directive, and it is available to CGIs via the SERVER_NAME environment variable.

The actual value used at run time is controlled by the UseCanonicalName setting.

With UseCanonicalName Off the server name comes from the contents of the Host: header in the request. With UseCanonicalName DNS it comes from a reverse DNS lookup of the virtual host's IP address. The former setting is used for name-based dynamic virtual hosting, and the latter is used for** IP-based hosting.

If Apache cannot work out the server name because there is no Host: header or the DNS lookup fails then the value configured with ServerName is used instead.

lista = list.sort(lista)

This should be

lista.sort()

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

sorted_list = sorted(lista)

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

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

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

is it simply

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

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

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

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

None[0]

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

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

other_list = sorted(lista)

The first solution did not work for me but here is some code that did work for me.

    private class WebClient : System.Net.WebClient
    {
        public int Timeout { get; set; }

        protected override WebRequest GetWebRequest(Uri uri)
        {
            WebRequest lWebRequest = base.GetWebRequest(uri);
            lWebRequest.Timeout = Timeout;
            ((HttpWebRequest)lWebRequest).ReadWriteTimeout = Timeout;
            return lWebRequest;
        }
    }

    private string GetRequest(string aURL)
    {
        using (var lWebClient = new WebClient())
        {
            lWebClient.Timeout = 600 * 60 * 1000;
            return lWebClient.DownloadString(aURL);
        }
    }

You can see in here: http://apidock.com/rails/ActionView/Helpers/FormBuilder/select

Or here: http://apidock.com/rails/ActionView/Helpers/FormOptionsHelper/select

Select tag has maximun 4 agrument, and last agrument is html option, it mean you can put class, require, selection option in here.

= f.select :sms_category_id, @sms_category_collect, {}, {class: 'form-control', required: true, selected: @set}

You can also use google-collections (guava) Joiner class if you want to customize the print format

Try this, it will combine your arrays removing duplicates

array1 = ["foo", "bar"]
array2 = ["foo1", "bar1"]

array3 = array1|array2

http://www.ruby-doc.org/core/classes/Array.html

Further documentation look at "Set Union"

JOIN t2 ON t1.id=t2.id AND t1.date=t2.date

Here, I am giving you a demo example. See this and customize it according to your need.

Hope this will solve your issue.

If you logged into "phpmyadmin", then logged out, you might have trouble attempting to log back in on the same browser window. The logout sends the browser to a URL that looks like this:

http://localhost/phpmyadmin/index.php?db=&token=354a350abed02588e4b59f44217826fd&old_usr=tester

But for me, on Mac OS X in Safari browser, that URL just doesn't want to work. Therefore, I have to put in the clean URL:

http://localhost/phpmyadmin

Don't know why, but as of today, Oct 20, 2015, that is what I am experiencing.

A real problem often exists because any variables set inside will not be exported when that batch file finishes. So its not possible to export, which caused us issues. As a result, I just set the registry to ALWAYS used delayed expansion (I don't know why it's not the default, could be speed or legacy compatibility issue.)

What worked for me :

  $where = '';
   /* $this->db->like('ust.title',$query_data['search'])
        ->or_like('usr.f_name',$query_data['search'])
        ->or_like('usr.l_name',$query_data['search']);*/
        $where .= "(ust.title like '%".$query_data['search']."%'";
        $where .= " or usr.f_name like '%".$query_data['search']."%'";
        $where .= "or usr.l_name like '%".$query_data['search']."%')";
        $this->db->where($where);



$datas = $this->db->join(TBL_USERS.' AS usr','ust.user_id=usr.id')
            ->where_in('ust.id', $blog_list) 
            ->select('ust.*,usr.f_name as f_name,usr.email as email,usr.avatar as avatar, usr.sex as sex')
            ->get_where(TBL_GURU_BLOG.' AS ust',[
                'ust.deleted_at'     =>  NULL,
                'ust.status'     =>  1,
            ]); 

I have to do this to create a query like this :

SELECT `ust`.*, `usr`.`f_name` as `f_name`, `usr`.`email` as `email`, `usr`.`avatar` as `avatar`, `usr`.`sex` as `sex` FROM `blog` AS `ust` JOIN `users` AS `usr` ON `ust`.`user_id`=`usr`.`id` WHERE (`ust`.`title` LIKE '%mer%' ESCAPE '!' OR  `usr`.`f_name` LIKE '%lok%' ESCAPE '!' OR  `usr`.`l_name` LIKE '%mer%' ESCAPE '!') AND `ust`.`id` IN('36', '37', '38') AND `ust`.`deleted_at` IS NULL AND `ust`.`status` = 1 ;

iterate through the list. if the current value is larger than the stored largest value, store it as the largest value and bump the 1-4 down and 5 drops off the list. If not,compare it to number 2 and do the same thing. Repeat, checking it against all 5 stored values. this should do it in O(n)

I think the xpath query you want goes something like this:

/xml/box[@stepId="$stepId"]/components/component[@id="$componentId"]/variables/variable[@nom="Enabled" and @valeur="Yes"]

This should get you the variables that are named "Enabled" with a value of "Yes" for the specified $stepId and $componentId. This is assuming that your xml starts with an tag like you show, and not

If the SQL Server 2005 XPath stuff is pretty straightforward (I've never used it), then the above query should work. Otherwise, someone else may have to help you with that.

If you're using Python 2.6 or newer you can use the grouper recipe from the itertools module:

from itertools import izip_longest

def grouper(n, iterable, fillvalue=None):
    "grouper(3, 'ABCDEFG', 'x') --> ABC DEF Gxx"
    args = [iter(iterable)] * n
    return izip_longest(fillvalue=fillvalue, *args)

Call like this:

for item1, item2 in grouper(2, l):
    # Do something with item1 and item2

Note that in Python 3.x you should use zip_longest instead of izip_longest.

The question of the post was avoiding e notation numbers and having the number as a plain number.

Therefore, if all is needed is to convert e (scientific) notation numbers to plain numbers (including in the case of fractional numbers) without loss of accuracy, then it is essential to avoid the use of the Math object and other javascript number methods so that rounding does not occur when large numbers and large fractions are handled (which always happens due to the internal storage in binary format).

The following function converts e (scientific) notation numbers to plain numbers (including fractions) handling both large numbers and large fractions without loss of accuracy as it does not use the built-in math and number functions to handle or manipulate the number.

The function also handles normal numbers, so that a number that is suspected to become in an 'e' notation can be passed to the function for fixing.

The function should work with different locale decimal points.

94 test cases are provided.

For large e-notation numbers pass the number as a string.

Examples:

eToNumber("123456789123456789.111122223333444455556666777788889999e+50");
// output:
"12345678912345678911112222333344445555666677778888999900000000000000"

eToNumber("123.456123456789123456895e-80");
// output:
"0.00000000000000000000000000000000000000000000000000000000000000000000000000000123456123456789123456895"

eToNumber("123456789123456789.111122223333444455556666777788889999e-50");
// output:
"0.00000000000000000000000000000000123456789123456789111122223333444455556666777788889999"

Valid e-notation numbers in Javascript include the following:

123e1   ==> 1230
123E1   ==> 1230
123e+1  ==> 1230
123.e+1 ==> 1230
123e-1  ==> 12.3
0.1e-1  ==> 0.01
.1e-1   ==> 0.01
-123e1  ==> -1230

Based on Dirk Stöcker's answer, here's a neat wrapper function for Python 3's print function. Use it just like you would use print.

As an added bonus, compared to the other answers, this won't print your text as a bytearray ('b"content"'), but as normal strings ('content'), because of the last decode step.

def uprint(*objects, sep=' ', end='\n', file=sys.stdout):
    enc = file.encoding
    if enc == 'UTF-8':
        print(*objects, sep=sep, end=end, file=file)
    else:
        f = lambda obj: str(obj).encode(enc, errors='backslashreplace').decode(enc)
        print(*map(f, objects), sep=sep, end=end, file=file)

uprint('foo')
uprint(u'Antonín Dvorák')
uprint('foo', 'bar', u'Antonín Dvorák')

make sure you push into an Array only and if their is error like Uncaught TypeError: data.push is not a function** then check for type of data you can do this by consol.log(data) hope this will help

The correct options are (in increasing order of recommendation):

# Single POSIX test command with -o operator (not recommended anymore).
# Quotes strongly recommended to guard against empty or undefined variables.
while [ "$stats" -gt 300 -o "$stats" -eq 0 ]

# Two POSIX test commands joined in a list with ||.
# Quotes strongly recommended to guard against empty or undefined variables.
while [ "$stats" -gt 300 ] || [ "$stats" -eq 0 ]

# Two bash conditional expressions joined in a list with ||.
while [[ $stats -gt 300 ]] || [[ $stats -eq 0 ]]

# A single bash conditional expression with the || operator.
while [[ $stats -gt 300 || $stats -eq 0 ]]

# Two bash arithmetic expressions joined in a list with ||.
# $ optional, as a string can only be interpreted as a variable
while (( stats > 300 )) || (( stats == 0 ))

# And finally, a single bash arithmetic expression with the || operator.
# $ optional, as a string can only be interpreted as a variable
while (( stats > 300 || stats == 0 ))

Some notes:

1. Quoting the parameter expansions inside [[ ... ]] and ((...)) is optional; if the variable is not set, -gt and -eq will assume a value of 0.

2. Using $ is optional inside (( ... )), but using it can help avoid unintentional errors. If stats isn't set, then (( stats > 300 )) will assume stats == 0, but (( $stats > 300 )) will produce a syntax error.

you may try this:-

myImgView.setImageDrawable(getResources().getDrawable(R.drawable.image_name));

You can join all regular expressions into single one. This way the string is scanned only once. Even with a sligthly more complex regular expression.

var thisExpressions = [ /something/, /something_else/, /and_something_else/];
var thisString = 'else';


function matchInArray(str, expr) {
    var fullExpr = new RegExp(expr
        .map(x=>x.source) // Just if you need to provide RegExp instances instead of strings or ...
        // .map(x=>x.substring(1, x.length -2)  // ...if you need to provide strings enclosed by "/" like in original question.
        .join("|")
    )
    return str.match(fullExpr);

};


if (matchInArray(thisString, thisExpressions)) {
    console.log ("Match!!");
} 

In fact, even with this approach, if you need check the same expression set against multiple strings, this is a few suboptimal because you are building (and compiling) the same regular expression each time the function is called.

Better approach would be to use a function builder like this:

var thisExpressions = [ /something/, /something_else/, /and_something_else/];
var thisString = 'else';

function matchInArray_builder(expr) {
    var fullExpr = new RegExp(expr
        .map(x=>x.source) // Just if you need to provide RegExp instances instead of strings or ...
        // .map(x=>x.substring(1, x.length -2)  // ...if you need to provide strings enclosed by "/" like in original question.
        .join("|")
    )   

    return function (str) {
        return str.match(fullExpr);

    };
};  

var matchInArray = matchInArray_builder(thisExpressions);

if (matchInArray(thisString)) {
    console.log ("Match!!");
} 

I came across this question when I was trying similar things.

If you know the width of the span you could just stuff in a left margin.

Try this:

.center { text-align: center}
div.center span { display: table; }

Add the "center: class to your .

If you want some spans centered, but not others, replace the "div.center span" in your style sheet to a class (e.g "center-span") and add that class to the span.

The following will parse an XML string into an XML document in all major browsers, including Internet Explorer 6. Once you have that, you can use the usual DOM traversal methods/properties such as childNodes and getElementsByTagName() to get the nodes you want.

var parseXml;
if (typeof window.DOMParser != "undefined") {
    parseXml = function(xmlStr) {
        return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
    };
} else if (typeof window.ActiveXObject != "undefined" &&
       new window.ActiveXObject("Microsoft.XMLDOM")) {
    parseXml = function(xmlStr) {
        var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.loadXML(xmlStr);
        return xmlDoc;
    };
} else {
    throw new Error("No XML parser found");
}

Example usage:

var xml = parseXml("<foo>Stuff</foo>");
alert(xml.documentElement.nodeName);

How about netstat?

http://support.microsoft.com/kb/907980

The command is netstat -anob.

(Make sure you run command as admin)

I get:

And If you want to check for the particular port, command to use is: netstat -aon | findstr 8080 from the same path

import array
integerValue = array.array("I", 'y\xcc\xa6\xbb')[0]

Warning: the above is strongly platform-specific. Both the "I" specifier and the endianness of the string->int conversion are dependent on your particular Python implementation. But if you want to convert many integers/strings at once, then the array module does it quickly.

git ls-tree --full-tree -r HEAD and git ls-files return all files at once. For a large project with hundreds or thousands of files, and if you are interested in a particular file/directory, you may find more convenient to explore specific directories. You can do it by obtaining the ID/SHA-1 of the directory that you want to explore and then use git cat-file -p [ID/SHA-1 of directory]. For example:

git cat-file -p 14032aabd85b43a058cfc7025dd4fa9dd325ea97
100644 blob b93a4953fff68df523aa7656497ee339d6026d64    glyphicons-halflings-regular.eot
100644 blob 94fb5490a2ed10b2c69a4a567a4fd2e4f706d841    glyphicons-halflings-regular.svg
100644 blob 1413fc609ab6f21774de0cb7e01360095584f65b    glyphicons-halflings-regular.ttf
100644 blob 9e612858f802245ddcbf59788a0db942224bab35    glyphicons-halflings-regular.woff
100644 blob 64539b54c3751a6d9adb44c8e3a45ba5a73b77f0    glyphicons-halflings-regular.woff2

In the example above, 14032aabd85b43a058cfc7025dd4fa9dd325ea97 is the ID/SHA-1 of the directory that I wanted to explore. In this case, the result was that four files within that directory were being tracked by my Git repo. If the directory had additional files, it would mean those extra files were not being tracked. You can add files using git add <file>... of course.

Based on semver, you can use

• Hyphen Ranges X.Y.Z - A.B.C 1.2.3-2.3.4 Indicates >=1.2.3 <=2.3.4

• X-Ranges 1.2.x 1.X 1.2.*

• Tilde Ranges ~1.2.3 ~1.2 Indicates allowing patch-level changes or minor version changes.

• Caret Ranges ^1.2.3 ^0.2.5 ^0.0.4

  Allows changes that do not modify the left-most non-zero digit in the [major, minor, patch] tuple

  • ^1.2.x (means >=1.2.0 <2.0.0)
  • ^0.0.x (means >=0.0.0 <0.1.0)
  • ^0.0 (means >=0.0.0 <0.1.0)

You are converting cert into BKS Keystore, why aren't you using .cert directly, from https://developer.android.com/training/articles/security-ssl.html:

CertificateFactory cf = CertificateFactory.getInstance("X.509");
InputStream instream = context.getResources().openRawResource(R.raw.gtux_cert);
Certificate ca;
try {
    ca = cf.generateCertificate(instream);
} finally {
    caInput.close();
}

KeyStore kStore = KeyStore.getInstance(KeyStore.getDefaultType());
kStore.load(null, null);
kStore.setCertificateEntry("ca", ca);

TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm(););
tmf.init(kStore);

SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);

okHttpClient.setSslSocketFactory(context.getSocketFactory());

You could probably trying using Yahoo or Google's APIs. They are generic, but by specifying the right set of parameters, you could probably narrow down the results to just hotels. Check out Yahoo's Local Search API and Google's Local Search API

Hi try this it will create directory + file inside it

File mediaDir = new File("/sdcard/download/media");
if (!mediaDir.exists()){
    mediaDir.mkdir();
}

File resolveMeSDCard = new File("/sdcard/download/media/hello_file.txt");
resolveMeSDCard.createNewFile();
FileOutputStream fos = new FileOutputStream(resolveMeSDCard);
fos.write(string.getBytes());
fos.close();

System.out.println("Your file has been written");  

Another way that the one described by danield is to have a child container width display inline, and the tipography color you want. The parent element width the text-decoration, and the color of underline you want. Like this:

div{text-decoration:underline;color:#ff0000;display:inline-block;width:50px}_x000D_
div span{color:#000;display:inline}

<div>_x000D_
  <span>Hover me, i can have many lines</span>_x000D_
</div>

With me this error ocurred when I copied and pasted a code in text format to my editor (gedit). The code was in a text document (.odt) and I copied it and pasted it into gedit. If you did the same, you have manually rewrite the code.

One detail hasn't been noted yet: modern desktop browsers consider different button presses to be "clicks" for AddEventListener('click' and onclick by default.

• On Chrome 42 and IE11, both onclick and AddEventListener click fire on left and middle click.
• On Firefox 38, onclick fires only on left click, but AddEventListener click fires on left, middle and right clicks.

Also, middle-click behavior is very inconsistent across browsers when scroll cursors are involved:

• On Firefox, middle-click events always fire.
• On Chrome, they won't fire if the middleclick opens or closes a scroll cursor.
• On IE, they fire when scroll cursor closes, but not when it opens.

It is also worth noting that "click" events for any keyboard-selectable HTML element such as input also fire on space or enter when the element is selected.

The answers here are outdated, as of today Sep 30 2016. Gmail is currently rolling out support for the style tag in the head, as well as media queries. If Gmail is your only concern, you're safe to use classes like a modern developer!

For reference, you can check the official gmail CSS docs.

As a side note, Gmail was the only major client that didn't support style (reference, until they update anyway). That means you can almost safely stop putting styles inline. Some of the more obscure clients may still need them.

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

You need to change your project settings so that Eclipse-CDT manages your Makefiles for you.

1. Select Project->Properties from the menu bar.
2. Click C/C++ Build on the left in the dialog that comes up.
3. Under the Builder Settings tab on the right, select "Generate Makefiles automatically" under the Makefile generation section.
4. Hit OK and build again.

Aside from @Verhás István answer (which I like), I was expecting a one-liner for the question:

${project.reporting.outputDirectory} resolves to target/site in your project.

I ran into this issue on Windows 7, running

npm install -g gulp

as administrator while being logged on as a normal user.

Solution: When executing the same installation as normal user (not "run as admin" for cmd) all was fine. I guess it is related to the default install and search path.

I just installed Node.js for the first time and it includes NPM, which can be ran from the Windows cmd. However, make sure that you run it as an administrator. Right click on cmd and choose "run as administrator". This allowed me to call npm commands.

You can add a jar in Eclipse by right-clicking on the Project ? Build Path ? Configure Build Path. Under Libraries tab, click Add Jars or Add External JARs and give the Jar. A quick demo here.

The above solution is obviously a "Quick" one. However, if you are working on a project where you need to commit files to the source control repository, I would recommend adding Jar files to a dedicated library folder within your source control repository and referencing few or all of them as mentioned above.

I can think of 2 ways to achieve this:

• IFNULL():

  The IFNULL() function returns a specified value if the expression is NULL.If the expression is NOT NULL, this function returns the expression.

Syntax:

IFNULL(expression, alt_value)

Example of IFNULL() with your query:

SELECT AVG( price )
FROM(
      SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
      WHERE listing_Type = 'AARM'
        AND u_kbalikepartnumbers_id = 1000307
        AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
        AND IFNULL( price, 0 ) > ( SELECT AVG( IFNULL( price, 0 ) )* 0.50
                                     FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) g
                                    WHERE cume_dist < 0.50
                                  )
        AND IFNULL( price, 0 ) < ( SELECT AVG( IFNULL( price, 0 ) ) *2
                                     FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) d
                                     WHERE cume_dist < 0.50)
     )s
HAVING COUNT(*) > 5

• COALESCE()

  The COALESCE() function returns the first non-null value in a list.

Syntax:

COALESCE(val1, val2, ...., val_n)

Example of COALESCE() with your query:

SELECT AVG( price )
FROM(
      SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
      WHERE listing_Type = 'AARM'
        AND u_kbalikepartnumbers_id = 1000307
        AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
        AND COALESCE( price, 0 ) > ( SELECT AVG( COALESCE( price, 0 ) )* 0.50
                                     FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) g
                                    WHERE cume_dist < 0.50
                                  )
        AND COALESCE( price, 0 ) < ( SELECT AVG( COALESCE( price, 0 ) ) *2
                                     FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) d
                                     WHERE cume_dist < 0.50)
     )s
HAVING COUNT(*) > 5

In java script calculate width using following code

var scrollX = $(window).width()*58/100;
var oTable = $('#reqAllRequestsTable').dataTable({
    "sScrollX": scrollX
    } );

Just add the & operator before the .exe name. Here is a command to install SQL Server Express in silence mode:

$fileExe = "T:\SQLEXPRADV_x64_ENU.exe"
$CONFIGURATIONFILE = "T:\ConfSetupSql2008Express.ini"

& $fileExe  /CONFIGURATIONFILE=$CONFIGURATIONFILE

Like this ?

<script>
var meta = document.createElement('meta');
meta.setAttribute('http-equiv', 'X-UA-Compatible');
meta.setAttribute('content', 'IE=Edge');
document.getElementsByTagName('head')[0].appendChild(meta);
</script>

The Code:

string myString = "Hello " + ((char)34) + " World." + ((char)34);

Output will be:

Hello "World."

The parent directory of an included file would be

dirname(getcwd())

e.g. the file is /var/www/html/folder/inc/file.inc.php which is included in /var/www/html/folder/index.php

then by calling /file/index.php

getcwd() is /var/www/html/folder  
__DIR__ is /var/www/html/folder/inc  
so dirname(__DIR__) is /var/www/html/folder

but what we want is /var/www/html which is dirname(getcwd())

.shape() gives the actual shape of your array in terms of no of elements in it, No of rows/No of Columns. The answer you get is in the form of tuples.

For Example: 1D ARRAY:

d=np.array([1,2,3,4])
print(d)
(1,)

Output: (4,) ie the number4 denotes the no of elements in the 1D Array.

2D Array:

e=np.array([[1,2,3],[4,5,6]])   
print(e)
(2,3)

Output: (2,3) ie the number of rows and the number of columns.

The number of elements in the final output will depend on the number of rows in the Array....it goes on increasing gradually.

This will work with "org.bouncycastle.util.encoders.Hex" following package

return new String(Hex.encode(digest));

Its in bouncycastle jar.

It is because display:inline-block takes into account white-space in the html. If you remove the white-space between the div's it works as expected. Live Example: http://jsfiddle.net/XCDsu/4/

<div id="col1">content</div><div id="col2">content</div>

I used the command

ansible -i inventory example -m ping -u <your_user_name> --ask-pass

And it will ask for your password.

For anyone who gets the error:

to use the 'ssh' connection type with passwords, you must install the sshpass program

On MacOS, you can follow below instructions to install sshpass:

1. Download the Source Code
2. Extract it and cd into the directory
3. ./configure
4. sudo make install

One more reason, maybe your url include some hiden characters, such as '\n'.

If you define your url like below, this exception will raise:

url = '''
http://google.com
'''

because there are '\n' hide in the string. The url in fact become:

\nhttp://google.com\n

If you do not have too many folders then I suggest you use if statements to choose an upload folder depending on the user input details. E.g.

String user= request.getParameter("username");
if (user=="Alfred"){
//Path A;
}
if (user=="other"){
//Path B;
}

EditText number1 = (EditText) layout.findViewById(R.id.edittext); 
number1.setInputType(InputType.TYPE_CLASS_NUMBER);

It works, when you use both lines:

Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000") = Format(Date, "yyyy-mm-dd")
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"

If you have a symbolic link in the /usr/local/etc/openssl pointing to cert.pem try to do this:

ruby -ropenssl -e "p OpenSSL::X509::DEFAULT_CERT_FILE" (should be /usr/local/etc/openssl)
cd /usr/local/etc/openssl
wget http://curl.haxx.se/ca/cacert.pem
ln -s cacert.pem 77ee3751.0 (77ee3751.0 is my symbolic link, should depend on the openssl version)

You can use the test command:

test -d $(OBJDIR) || mkdir $(OBJDIR)

This should probably be a comment, however, I don't have enough reputation to comment.

I suggest you really use the table (HTML) instead of ion-row and ion-col. Things will not look nice when one of the cell's content is too long.

One worse case looks like this:

| 10 | 20 | 30 | 40 |
| 1 | 2 | 3100 | 41 |

Higher fidelity example fork from @jpoveda

Call the pd.DataFrame constructor directly:

df = pd.DataFrame(table, columns=headers)
df

   Heading1  Heading2
0         1         2
1         3         4

To clear some confusion:

This is done in 2 steps: Setting the button background attribute to android:attr/selectableItemBackground creates you a button with feedback but no background.

android:background="?android:attr/selectableItemBackground"

The line to divide the borderless button from the rest of you layout is done by a view with the background android:attr/dividerVertical

android:background="?android:attr/dividerVertical"

For a better understanding here is a layout for a OK / Cancel borderless button combination at the bottom of your screen (like in the right picture above).

<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:layout_alignParentBottom="true">
        <View

            android:layout_marginLeft="4dip"
            android:layout_marginRight="4dip"
            android:background="?android:attr/dividerVertical"
            android:layout_alignParentTop="true"/>

We are using Play version 2.5.6.

For changing the port, go to your project root folder and hit: activator "run 8008" in command prompt / terminal.

and that's it.

If your datetime object represents UTC time, don't use time.mktime, as it assumes the tuple is in your local timezone. Instead, use calendar.timegm:

>>> import datetime, calendar
>>> d = datetime.datetime(1970, 1, 1, 0, 1, 0)
>>> calendar.timegm(d.timetuple())
60

Date.prototype.addDays = function(days)
{
    var dat = new Date(this.valueOf() + days * 24 * 60 * 60 * 1000 );
    return dat;
}

If you want to use hex codes, you should add -e option to enable interpretation of backslash escapes by echo (but the result is the same as with echoCtrlRCtrlB). And as wallyk said, you probably want to add -n to prevent the output of a newline:

echo -en '\x12\x02' > /dev/ttyS0

Also make sure that /dev/ttyS0 is the port you want.

Why do you want to reinvent the wheel when there are opensource that are already doing the job pretty nicely.

Both apache common-langs and spring support some very flexible builder pattern

For apache, here is how you do it reflectively

@Override
public String toString()
{
  return ToStringBuilder.reflectionToString(this);
}

Here is how you do it if you only want to print fields that you care about.

@Override
public String toString() 
{
    return new ToStringBuilder(this)
      .append("name", name)
      .append("location", location)
      .append("address", address)
      .toString(); 
}

You can go as far as "styling" your print output with non-default ToStringStyle or even customizing it with your own style.

I didn't personally try spring ToStringCreator api, but it looks very similar.

Get<S, T> takes two type arguments. When you call service.Get(new Signatur()); how does the compiler know what T is? You'll have to pass it explicitly or change something else about your type hierarchies. Passing it explicitly would look like:

service.Get<Signatur, bool>(new Signatur());

The sessions are handled by the NAS device. What you are asking is dependant on the NAS device and nothing to do with windows. You would have to have a look into your NAS firmware to see to what it support. The only other way is sniff the packets and work it out yourself.

In the package explorer and the navigation screen you should now see the project you created. Note that eclipse will not copy your files, it will just allow you to use the existing source and edit it from eclipse.

As @epascarello mentioned for W3C standard browsers, you should use:

body.addEventListener("load", init, false);

However, if you want it to work on IE<9 as well you can use:

var prefix = window.addEventListener ? "" : "on";
var eventName = window.addEventListener ? "addEventListener" : "attachEvent";
document.body[eventName](prefix + "load", init, false);

Or if you want it in a single line:

document.body[window.addEventListener ? 'addEventListener' : 'attachEvent'](
    window.addEventListener ? "load" : "onload", init, false);

Note: here I get a straight reference to the body element via the document, saving the need for the first line.

Also, if you're using jQuery, and you want to use the DOM ready event rather than when the body loads, the answer can be even shorter...

$(init);

This implementation:

• Has no code duplication
• Doesn't require extra functions()
• Doesn't depend on the return value of code in the "while" section of the loop:

do=true
while $do || conditions; do
  do=false
  # your code ...
done

It works with a read loop, too, skipping the first read:

do=true
while $do || read foo; do
  do=false

  # your code ...
  echo $foo
done

Does your upload die at the very end? 99% before crashing? Client body and buffers are key because nginx must buffer incoming data. The body configs (data of the request body) specify how nginx handles the bulk flow of binary data from multi-part-form clients into your app's logic.

The clean setting frees up memory and consumption limits by instructing nginx to store incoming buffer in a file and then clean this file later from disk by deleting it.

Set body_in_file_only to clean and adjust buffers for the client_max_body_size. The original question's config already had sendfile on, increase timeouts too. I use the settings below to fix this, appropriate across your local config, server, & http contexts.

client_body_in_file_only clean;
client_body_buffer_size 32K;

client_max_body_size 300M;

sendfile on;
send_timeout 300s;

Another approach is to append the submit input button to the form only when it is supposed to be submited and replace it by a simple div during the form filling

In my case, I had a very similar problem. I was updating my view inside a function that was being called by a parent component, and in my parent component I forgot to use @ViewChild(NameOfMyChieldComponent). I lost at least 3 hours just for this stupid mistake. i.e: I didn't need to use any of those methods:

• ChangeDetectorRef.detectChanges()
• ChangeDetectorRef.markForCheck()
• ApplicationRef.tick()

The relative pathing is based on the document level of the client side i.e. the URL level of the document as seen in the browser.

If the URL of your website is: http://www.example.com/mywebsite/ then starting at the root level starts above the "mywebsite" folder path.

Expanding on plowman's answer, here is the non-deprecated version of changing the background image with java.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Bitmap bmp = BitmapFactory.decodeResource(getResources(),
            R.drawable.texture);
    BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(),bmp);
    bitmapDrawable.setTileModeXY(Shader.TileMode.REPEAT,
            Shader.TileMode.REPEAT);
    setBackground(bitmapDrawable);
}

Nested 'With' is not supported, but you can always use the second With as a subquery, for example:

WITH A AS (
                --WITH B AS ( SELECT COUNT(1) AS _CT FROM C ) SELECT CASE _CT WHEN 1 THEN 1 ELSE 0 END FROM B --doesn't work
                SELECT CASE WHEN count = 1 THEN 1 ELSE 0 END AS CT FROM (SELECT COUNT(1) AS count FROM dual)
                union all
                select 100 AS CT from dual
           )
              select CT FROM A

x[r,]

where r is the row you're interested in. Try this, for example:

#Add your data
x <- structure(list(A = c(5,    3.5, 3.25, 4.25,  1.5 ), 
                    B = c(4.25, 4,   4,    4.5,   4.5 ),
                    C = c(4.5,  2.5, 4,    2.25,  3   )
               ),
               .Names    = c("A", "B", "C"),
               class     = "data.frame",
               row.names = c(NA, -5L)
     )

#The vector your result should match
y<-c(A=5, B=4.25, C=4.5)

#Test that the items in the row match the vector you wanted
x[1,]==y

This page (from this useful site) has good information on indexing like this.

A Monitor is an object designed to be accessed from multiple threads. The member functions or methods of a monitor object will enforce mutual exclusion, so only one thread may be performing any action on the object at a given time. If one thread is currently executing a member function of the object then any other thread that tries to call a member function of that object will have to wait until the first has finished.

A Semaphore is a lower-level object. You might well use a semaphore to implement a monitor. A semaphore essentially is just a counter. When the counter is positive, if a thread tries to acquire the semaphore then it is allowed, and the counter is decremented. When a thread is done then it releases the semaphore, and increments the counter.

If the counter is already zero when a thread tries to acquire the semaphore then it has to wait until another thread releases the semaphore. If multiple threads are waiting when a thread releases a semaphore then one of them gets it. The thread that releases a semaphore need not be the same thread that acquired it.

A monitor is like a public toilet. Only one person can enter at a time. They lock the door to prevent anyone else coming in, do their stuff, and then unlock it when they leave.

A semaphore is like a bike hire place. They have a certain number of bikes. If you try and hire a bike and they have one free then you can take it, otherwise you must wait. When someone returns their bike then someone else can take it. If you have a bike then you can give it to someone else to return --- the bike hire place doesn't care who returns it, as long as they get their bike back.

In the future (perhaps) you will be able to use :nth-child(an+b of s)

Actually, browser support for the “of” filter is very limited. Only Safari seems to support the syntax.

https://css-tricks.com/almanac/selectors/n/nth-child/

The INSERT command doesn't have a WHERE clause - you'll have to write it like this:

ALTER PROCEDURE [dbo].[EmailsRecebidosInsert]
  (@_DE nvarchar(50),
   @_ASSUNTO nvarchar(50),
   @_DATA nvarchar(30) )
AS
BEGIN
   IF NOT EXISTS (SELECT * FROM EmailsRecebidos 
                   WHERE De = @_DE
                   AND Assunto = @_ASSUNTO
                   AND Data = @_DATA)
   BEGIN
       INSERT INTO EmailsRecebidos (De, Assunto, Data)
       VALUES (@_DE, @_ASSUNTO, @_DATA)
   END
END

>>> myseries[myseries == 7]
3    7
dtype: int64
>>> myseries[myseries == 7].index[0]
3

Though I admit that there should be a better way to do that, but this at least avoids iterating and looping through the object and moves it to the C level.

It's a bit late but I came across this post.

It's not perfect but here's what I do.

HTML Code

<div class="showcase-menu-social"><img class="margin-left-20" src="images/graphics/facebook-50x50.png" alt="facebook-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/twitter-50x50.png" alt="twitter-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/youtube-50x50.png" alt="youtube-50x50" width="50" height="50" /></div>

CSS Code

.showcase-menu {
  margin-left:20px;
    margin-right:20px;
    padding: 0px 20px 0px 20px;
    background-color: #C37500;
    behavior: url(/css/border-radius.htc);
  border-radius: 20px;
    }

.showcase-menu-social img:hover {
  background-color: #C37500;
  opacity:0.7 !important;
  filter:alpha(opacity=70) !important; /* For IE8 and earlier */
  box-shadow: 0 0 0px #000000 !important;
}

Now my border radius of 20px matches up exactly with the image border radius. As you can see the .showcase-menu has the same background as the .showcase-menu-social. What this does is to allow the 'opacity' to take effect and no 'square' background or border shows, thus the image slightly reduces it's saturation on hover.

It's a nice effect and does give the viewer the feedback that the image is in focus. I'm fairly sure on a darker background, it would have even a better effect.

The nice thing is that this is valid HTML-CSS code and will validate. To be honest, it should work on non-image elements just as good as images.

Enjoy!

Method overloading can come in handy here Like:

<code>
public class myClass 
{
    int add(int a, int b) 
    {
         return (a + b);
    }

    String add(String a, String b)
    {
         return (c + d);
    }

    public static void main(String args[]) 
    {
        myClass ob1 = new myClass);
        ob1.add(2, 3);
        //will return 5
        ob1.add("Hello, ", "World!");
        //will return Hello, World!
    }

}

I am by no means an OCR expert. But I this week had need to convert text out of a jpg.

I started with a colorized, RGB 445x747 pixel jpg. I immediately tried tesseract on this, and the program converted almost nothing. I then went into GIMP and did the following. image>mode>grayscale image>scale image>1191x2000 pixels filters>enhance>unsharp mask with values of radius = 6.8, amount = 2.69, threshold = 0 I then saved as a new jpg at 100% quality.

Tesseract then was able to extract all the text into a .txt file

Gimp is your friend.

Scripts are loaded in the order you have defined them in the HTML.

Therefore if you first load:

<script type="text/javascript" src="./javascript.js"></script>

without loading jQuery first, then $ is not defined.

You need to first load jQuery so that you can use it.

I would also recommend placing your scripts at the bottom of your HTML for performance reasons.

"Better" is subjective.

querySelector is the newer feature.

getElementById is better supported than querySelector.

querySelector is better supported than getElementsByClassName.

querySelector lets you find elements with rules that can't be expressed with getElementById and getElementsByClassName

You need to pick the appropriate tool for any given task.

(In the above, for querySelector read querySelector / querySelectorAll).

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

Its simple, use

  Form.ShowDialog();

Instead

  Form.Show();

While using Form.ShowDialog()you cannot interact with the parent form until it closes.

Use this echo statement

 echo -e "Hai\nHello\nTesting\n"

The output is

Hai
Hello
Testing

Run docker login

Push the image to docker hub

Re-create pod

This solved the problem for me. Hope it helps.

If you use VisualSVN Server, you can find out the version number by several different means.

Use VisualSVN Server Manager

Follow these steps to find out the version via the management console:

1. Start the VisualSVN Server Manager console.
2. See the Version at the bottom-right corner of the dashboard.

If you click Version you will also see the versions of the components.

Check the README.txt file

Follow these steps to find out the version from the readme.txt file:

1. Start notepad.exe.
2. Open the %VISUALSVN_SERVER%README.txt file. The first line shows the version number.

Simply call InetAddress.getByName(String host) passing in your textual IP address.

From the javadoc: The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address.

RESTful Resource controller

A RESTful resource controller sets up some default routes for you and even names them.

Route::resource('users', 'UsersController');

Gives you these named routes:

Verb          Path                        Action  Route Name
GET           /users                      index   users.index
GET           /users/create               create  users.create
POST          /users                      store   users.store
GET           /users/{user}               show    users.show
GET           /users/{user}/edit          edit    users.edit
PUT|PATCH     /users/{user}               update  users.update
DELETE        /users/{user}               destroy users.destroy

And you would set up your controller something like this (actions = methods)

class UsersController extends BaseController {

    public function index() {}

    public function show($id) {}

    public function store() {}

}

You can also choose what actions are included or excluded like this:

Route::resource('users', 'UsersController', [
    'only' => ['index', 'show']
]);

Route::resource('monkeys', 'MonkeysController', [
    'except' => ['edit', 'create']
]);

API Resource controller

Laravel 5.5 added another method for dealing with routes for resource controllers. API Resource Controller acts exactly like shown above, but does not register create and edit routes. It is meant to be used for ease of mapping routes used in RESTful APIs - where you typically do not have any kind of data located in create nor edit methods.

Route::apiResource('users', 'UsersController');

RESTful Resource Controller documentation

Implicit controller

An Implicit controller is more flexible. You get routed to your controller methods based on the HTTP request type and name. However, you don't have route names defined for you and it will catch all subfolders for the same route.

Route::controller('users', 'UserController');

Would lead you to set up the controller with a sort of RESTful naming scheme:

class UserController extends BaseController {

    public function getIndex()
    {
        // GET request to index
    }

    public function getShow($id)
    {
        // get request to 'users/show/{id}'
    }

    public function postStore()
    {
        // POST request to 'users/store'
    }

}

Implicit Controller documentation

It is good practice to use what you need, as per your preference. I personally don't like the Implicit controllers, because they can be messy, don't provide names and can be confusing when using php artisan routes. I typically use RESTful Resource controllers in combination with explicit routes.

I think you can use ndmin option of numpy.array. Keeping it to 2 says that it will be a (4,1) and transpose will be (1,4).

>>> a = np.array([12, 3, 4, 5], ndmin=2)
>>> print a.shape
>>> (1,4)
>>> print a.T.shape
>>> (4,1)

Not true for the OP, but this error can be caused by using single quotation marks (') instead of double (") for strings.

The JSON spec requires double quotation marks for strings.

E.g:

JSON.parse(`{"myparam": 'myString'}`)

gives the error, whereas

JSON.parse(`{"myparam": "myString"}`)

does not. Note the quotation marks around myString.

How to do it programatically :

To enable EditText use:

et.setEnabled(true);

To disable EditText use:

et.setEnabled(false);

If this is ASP.net-Core then you are mixing web API versions. Have the action return a derived IActionResult because in your current code the framework is treating HttpResponseMessage as a model.

[Route("api/[controller]")]
public class DownloadController : Controller {
    //GET api/download/12345abc
    [HttpGet("{id}"]
    public async Task<IActionResult> Download(string id) {
        Stream stream = await {{__get_stream_based_on_id_here__}}

        if(stream == null)
            return NotFound(); // returns a NotFoundResult with Status404NotFound response.

        return File(stream, "application/octet-stream"); // returns a FileStreamResult
    }    
}

I was getting the error “gcc: error: x86_64-linux-gnu-gcc: No such file or directory” as I was trying to build a simple c-extension module to run in Python. I tried all the things above to no avail, and finally realized that I had an error in my module.c code! So I thought it would be helpful to add that, if you are getting this error message but you have python-dev and everything correctly installed, you should look for issues in your code.

As others have mentioned, you should avoid macros whenever possible. They are dangerous in the presence of side effects if the macro arguments are evaluated more than once. If you know the type of the arguments (or can use C++0x auto feature), you could use temporaries to enforce single evaluation.

Another problem: the order in which multiple evaluations happen may not be what you expect!

Consider this code:

#include <iostream>
using namespace std;

int foo( int & i ) { return i *= 10; }
int bar( int & i ) { return i *= 100; }

#define BADMACRO( X, Y ) do { \
    cout << "X=" << (X) << ", Y=" << (Y) << ", X+Y=" << ((X)+(Y)) << endl; \
    } while (0)

#define MACRO( X, Y ) do { \
    int x = X; int y = Y; \
    cout << "X=" << x << ", Y=" << y << ", X+Y=" << ( x + y ) << endl; \
    } while (0)

int main() {
    int a = 1; int b = 1;
    BADMACRO( foo(a), bar(b) );
    a = 1; b = 1;
    MACRO( foo(a), bar(b) );
    return 0;
}

And it's output as compiled and run on my machine:

X=100, Y=10000, X+Y=110
X=10, Y=100, X+Y=110

No.

You get charged for:

1. Online time
2. Storage space (assumably you store the image on S3 [EBS])
3. Elastic IP addresses
4. Bandwidth

So... if you stop the EC2 instance you will only have to pay for the storage of the image on S3 (assuming you store an image ofcourse) and any IP addresses you've reserved.

This isn't exactly optimized, but it should work.

var chars = "ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";
var string_length = 8;
var randomstring = '';
var charCount = 0;
var numCount = 0;

for (var i=0; i<string_length; i++) {
    // If random bit is 0, there are less than 3 digits already saved, and there are not already 5 characters saved, generate a numeric value. 
    if((Math.floor(Math.random() * 2) == 0) && numCount < 3 || charCount >= 5) {
        var rnum = Math.floor(Math.random() * 10);
        randomstring += rnum;
        numCount += 1;
    } else {
        // If any of the above criteria fail, go ahead and generate an alpha character from the chars string
        var rnum = Math.floor(Math.random() * chars.length);
        randomstring += chars.substring(rnum,rnum+1);
        charCount += 1;
    }
}

alert(randomstring);

Here's a jsfiddle for you to test on: http://jsfiddle.net/sJGW4/3/

Generalizing on martinedwards and others' ideas, you can glue a bunch of columns together (not just a pair) by adjusting padding of even and odd column children. Adding this definition of a class, .no-gutter, and placing it on your .row element

.row.no-gutter > [class*='col-']:nth-child(2n+1) {
    padding-right: 0;
 } 

.row.no-gutter > [class*='col-']:nth-child(2n) {
    padding-left: 0;
}

Or in SCSS:

.no-gutter  {
    > [class*='col-'] {
        &:nth-child(2n+1) {
            padding-right: 0;
        }
        &:nth-child(2n) {
            padding-left: 0;
        }
    }
}

The correct way to use max in the having clause is by performing a self join first:

select t1.a, t1.b, t1.c
from table1 t1
join table1 t1_max
  on t1.id = t1_max.id
group by t1.a, t1.b, t1.c
having t1.date = max(t1_max.date)

The following is how you would join with a subquery:

select t1.a, t1.b, t1.c
from table1 t1
where t1.date = (select max(t1_max.date)
                 from table1 t1_max
                 where t1.id = t1_max.id)

Be sure to create a single dataset before using an aggregate when dealing with a multi-table join:

select t1.id, t1.date, t1.a, t1.b, t1.c
into #dataset
from table1 t1
join table2 t2
  on t1.id = t2.id
join table2 t3
  on t1.id = t3.id


select a, b, c
from #dataset d
join #dataset d_max
  on d.id = d_max.id
having d.date = max(d_max.date)
group by a, b, c

Sub query version:

select t1.id, t1.date, t1.a, t1.b, t1.c
into #dataset
from table1 t1
join table2 t2
  on t1.id = t2.id
join table2 t3
  on t1.id = t3.id


select a, b, c
from #dataset d
where d.date = (select max(d_max.date)
                from #dataset d_max
                where d.id = d_max.id)

let lang = window.navigator.languages ? window.navigator.languages[0] : null;_x000D_
    lang = lang || window.navigator.language || window.navigator.browserLanguage || window.navigator.userLanguage;_x000D_
_x000D_
let shortLang = lang;_x000D_
if (shortLang.indexOf('-') !== -1)_x000D_
    shortLang = shortLang.split('-')[0];_x000D_
_x000D_
if (shortLang.indexOf('_') !== -1)_x000D_
    shortLang = shortLang.split('_')[0];_x000D_

console.log(lang, shortLang);

I only needed the primary component for my needs, but you can easily just use the full string. Works with latest Chrome, Firefox, Safari and IE10+.

Index the list then the dict.

print L[1]['d']

As @weichsel stated, CGFloat is just a typedef for either float or double. You can see for yourself by Command-double-clicking on "CGFloat" in Xcode — it will jump to the CGBase.h header where the typedef is defined. The same approach is used for NSInteger and NSUInteger as well.

These types were introduced to make it easier to write code that works on both 32-bit and 64-bit without modification. However, if all you need is float precision within your own code, you can still use float if you like — it will reduce your memory footprint somewhat. Same goes for integer values.

I suggest you invest the modest time required to make your app 64-bit clean and try running it as such, since most Macs now have 64-bit CPUs and Snow Leopard is fully 64-bit, including the kernel and user applications. Apple's 64-bit Transition Guide for Cocoa is a useful resource.

Run a test.

   string coerce:          7.42296099663
   string cast:            8.05654597282
   string fail coerce:     7.14159703255
   string fail cast:       7.87444186211

This was a test that ran each scenario 10,000,000 times. :-)

Co-ercion is 0 + "123"

Casting is (integer)"123"

I think Co-ercion is a tiny bit faster. Oh, and trying 0 + array('123') is a fatal error in PHP. You might want your code to check the type of the supplied value.

My test code is below.

function test_string_coerce($s) {
    return 0 + $s;
}

function test_string_cast($s) {
    return (integer)$s;
}

$iter = 10000000;

print "-- running each text $iter times.\n";

// string co-erce
$string_coerce = new Timer;
$string_coerce->Start();

print "String Coerce test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('123');
}

$string_coerce->Stop();

// string cast
$string_cast = new Timer;
$string_cast->Start();

print "String Cast test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('123');
}

$string_cast->Stop();

// string co-erce fail.
$string_coerce_fail = new Timer;
$string_coerce_fail->Start();

print "String Coerce fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('hello');
}

$string_coerce_fail->Stop();

// string cast fail
$string_cast_fail = new Timer;
$string_cast_fail->Start();

print "String Cast fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('hello');
}

$string_cast_fail->Stop();

// -----------------
print "\n";
print "string coerce:          ".$string_coerce->Elapsed()."\n";
print "string cast:            ".$string_cast->Elapsed()."\n";
print "string fail coerce:     ".$string_coerce_fail->Elapsed()."\n";
print "string fail cast:       ".$string_cast_fail->Elapsed()."\n";


class Timer {
    var $ticking = null;
    var $started_at = false;
    var $elapsed = 0;

    function Timer() {
        $this->ticking = null;
    }

    function Start() {
        $this->ticking = true;
        $this->started_at = microtime(TRUE);
    }

    function Stop() {
        if( $this->ticking )
            $this->elapsed = microtime(TRUE) - $this->started_at;
        $this->ticking = false;
    }

    function Elapsed() {
        switch( $this->ticking ) {
            case true: return "Still Running";
            case false: return $this->elapsed;
            case null: return "Not Started";
        }
    }
}

You can use hexdump's

import hexdump
hexdump.dump("Hello World", sep=":")

(append .lower() if you require lower-case). This works for both Python 2 & 3.

Both of your examples should behave pretty much the same.

A value returned inside a then() handler becomes the resolution value of the promise returned from that then(). If the value returned inside the .then is a promise, the promise returned by then() will "adopt the state" of that promise and resolve/reject just as the returned promise does.

In your first example, you return "bbb" in the first then() handler, so "bbb" is passed into the next then() handler.

In your second example, you return a promise that is immediately resolved with the value "bbb", so "bbb" is passed into the next then() handler. (The Promise.resolve() here is extraneous).

The outcome is the same.

If you can show us an example that actually exhibits different behavior, we can tell you why that is happening.

You can clear out their values by just setting value to an empty string:

var1.value = '';
var2.value = '';

Alternatively , you can use vectors to get a writable char* as demonstrated below;

//this handles memory manipulations and is more convenient
string str;
vector <char> writable (str.begin (), str.end) ;
writable .push_back ('\0'); 
char* cstring = &writable[0] //or &*writable.begin () 

//Goodluck  

This should do what you need.

var enumType = typeof(FunkyAttributesEnum);
var memberInfos = enumType.GetMember(FunkyAttributesEnum.NameWithoutSpaces1.ToString());
var enumValueMemberInfo = memberInfos.FirstOrDefault(m => m.DeclaringType == enumType);
var valueAttributes = 
      enumValueMemberInfo.GetCustomAttributes(typeof(DescriptionAttribute), false);
var description = ((DescriptionAttribute)valueAttributes[0]).Description;

Add the below entry to your .bowerrc:

{
  "proxy":"http://<user>:<password>@<host>:<port>",
  "https-proxy":"http://<user>:<password>@<host>:<port>"
}

Also if your password contains any special character URL-encode it Eg: replace the @ character with %40

I get this fairly regularily. Currently what's working for me (with Photon) is:

• Close project
• Open project

If this doesn't work :

• Close project
• Exit Eclipse
• Restart Eclipse
• Open Project

I know, stupid isn't it.

document.querySelector('#from1').onsubmit = function(e){

    confirmButtonColor: '#DD6B55',

Here is an out of the box future proof date snippet. Firefox defaults to jquery ui datepicker. Otherwise HTML5 datepicker is used. If FF ever support HTML5 type="date" the script will simply be redundant. Dont forget the three dependencies are needed in the head tag.

<script>
  src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js">
</script>
<link rel="stylesheet"href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">  
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

<!--Form element uses HTML 5 type="date"-->
<div class="form-group row">
    <label for="date" class="col-sm-2 col-form-label"Date</label>
    <div class="col-sm-10">          
       <input type="date" class="form-control" name="date" id="date" placeholder="date">
    </div>
</div>

<!--if the user is using FireFox it          
autoconverts type='date' into type='text'. If the type is text the 
script below will assign the jquery ui datepicker with options-->
<script>
$(function() 
{
  var elem = document.createElement('input');
  elem.setAttribute('type', 'date');

  if ( elem.type === 'text' ) 
  {
    $('#date').datepicker();
    $( "#date" ).datepicker( "option", "dateFormat", 'yy-mm-dd' );     
  }
});

You can use CSS for that.

HTML (only for demo, it is customizable)

<div class="button">
    <input type="radio" name="a" value="a" id="a" />
    <label for="a">a</label>
</div>
<div class="button">
    <input type="radio" name="a" value="b" id="b" />
    <label for="b">b</label>
</div>
<div class="button">
    <input type="radio" name="a" value="c" id="c" />
    <label for="c">c</label>
</div>
...

CSS

input[type="radio"] {
    display: none;
}
input[type="radio"]:checked + label {
    border: 1px solid red;
}

Starting from material components android 1.2.0-alpha01, you have slider component

ex:

<com.google.android.material.slider.Slider
        android:id="@+id/slider"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:valueFrom="20f"
        android:valueTo="70f"
        android:stepSize="10" />

Chris Beeley is rigth, you only need the proportions by column. Using your data is:

 your_matrix<-( 
               rbind(
                       c(23,234,324), 
                       c(34,534,12), 
                       c(56,324,124), 
                       c(34,234,124),
                       c(123,534,654)
                    )
                )

 barplot(prop.table(your_matrix, 2) )

Gives:

Since Android Studio 3.2 and Android Emulator 27.3.8 - the android emulator is supported by Windows Hypervisor Platform and as stated in the official android developer blog - there is mac support (since OS X v10.10 Yosemite) and windows support (since April 2018 Update). You may find further instructions on the developer blog.

In my opinion, the performance is significantly better than all previous workarounds.

Roughly you can do it like that :

try
{
    //do something
}
catch (Exception ex)
{
    string script = "<script>alert('" + ex.Message + "');</script>";
    if (!Page.IsStartupScriptRegistered("myErrorScript"))
    {
         Page.ClientScript.RegisterStartupScript("myErrorScript", script);
    }
}

But I recommend you to define your custom Exception and throw it anywhere you need. At your page catch this custom exception and register your message box script.

It should be a Python expression that, when eval'd, creates an object with the exact same properties as this one. For example, if you have a Fraction class that contains two integers, a numerator and denominator, your __repr__() method would look like this:

# in the definition of Fraction class
def __repr__(self):
    return "Fraction(%d, %d)" % (self.numerator, self.denominator)

Assuming that the constructor takes those two values.

I checked the IL on several answers. This code efficiently provides an empty List:

    using System.Linq;
    …
    var list = new[]{new{Id = default(int), Name = default(string)}}.Skip(1).ToList();

Getting overly clever with obscure-er HTTP error codes is a bad idea. Browsers sometimes react in unhelpful ways that obfuscate the situation. Stick with 404.

The easiest process to symbolicate crash logs:

1. preserve the xcarchive file from the organizer during IPA building process for future use.
2. When the crash occurs, collect the crash logs from affected device. The extension should be .crash. If the crash log is in .ips format, just rename it to .crash.
3. Double click the xcarchive from the stored path to make it appear in organizer(if not present already).
4. open in xcode window->devices and simulators -> view device logs -> all logs -> drag and drop the .crash file.

Wait for 5secs. Bang! the application calls in stack trace will be symbolicated! You may still see a lot of symbols though! those are internal library and framework calls.

This is the easiest one, tried and tested!

Environment variables (that you modify using the System Properties) are only propagated to subshells when you create a new subshell.

If you had a command line prompt (DOS or cygwin) open when you changed the User env vars, then they won't show up.

You need to open a new command line prompt after you change the user settings.

The equivalent in Unix/Linux is adding a line to your .bash_rc: you need to start a new shell to get the values.

I've just had this same issue with Ionic.

It turns out nothing was wrong with my code, I simply had to quit the ionic serve session and run ionic serve again.

After going back into the app, my states worked fine.

I would also suggest pressing save on your app.js file a few times if you are running gulp, to make sure everything gets re-compiled.

Try this -

 select * from table where id in (3,4) or [name] in ('andy','paul');

Although there are so many answers to the question, I would like to share our experience of creating the endless list view. We have recently implemented custom Carousel LayoutManager that can work in the cycle by scrolling the list infinitely as well as up to a certain point. Here is a detailed description on GitHub.

I suggest you take a look at this article with short but valuable recommendations on creating custom LayoutManagers: http://cases.azoft.com/create-custom-layoutmanager-android/

Using JQuery : http://api.jquery.com/hide/

$('li.two').hide()

    <li class="one">a</li>
    <li class="two">b</li>
    <li class="three">c</li>
</ul>

Don't know who looks at your file, but if you open it in wordpad instead of notepad, the linebreaks will show correct. In case you're using a special file extension, associate it with wordpad and you're done with it. Or use any other more advanced text editor.

For debian/ubuntu install

sudo apt-get install php-pgsql

Unfortunately this isn't entirely possible as the ClassLoader won't tell you what classes are available. You can, however, get fairly close doing something like this:

for (String classpathEntry : System.getProperty("java.class.path").split(System.getProperty("path.separator"))) {
    if (classpathEntry.endsWith(".jar")) {
        File jar = new File(classpathEntry);

        JarInputStream is = new JarInputStream(new FileInputStream(jar));

        JarEntry entry;
        while( (entry = is.getNextJarEntry()) != null) {
            if(entry.getName().endsWith(".class")) {
                // Class.forName(entry.getName()) and check
                //   for implementation of the interface
            }
        }
    }
}

Edit: johnstok is correct (in the comments) that this only works for standalone Java applications, and won't work under an application server.
