The only sure shot way to do this is to call CreateFile() on all \\.\Physicaldiskx where x is from 0 to 15 (16 is maximum number of disks allowed). Check the returned handle value. If invalid check GetLastError() for ERROR_FILE_NOT_FOUND. If it returns anything else then the disk exists but you cannot access it for some reason.

A good alternative is this:

find . -type f | xargs chmod -v 644

and for directories:

find . -type d | xargs chmod -v 755

and to be more explicit:

find . -type f | xargs -I{} chmod -v 644 {}

Here is an alternative method for doing multiple args. I use it when the arguments are too long for a one liner.

$app = 'C:\Program Files\MSBuild\test.exe'
$arg1 = '/genmsi'
$arg2 = '/f'
$arg3 = '$MySourceDirectory\src\Deployment\Installations.xml'

& $app $arg1 $arg2 $arg3

Add the css

  <style type="text/css">
    textarea
    {

        border:1px solid #999999
        width:99%;
        margin:5px 0;
        padding:1%;
    }
</style>

Here's a solution for you, using only one very tiny and simple image and one automatically generated span element:

CSS

span.stars, span.stars span {
    display: block;
    background: url(stars.png) 0 -16px repeat-x;
    width: 80px;
    height: 16px;
}

span.stars span {
    background-position: 0 0;
}

Image

_{(source: ulmanen.fi)}

Note: do NOT hotlink to the above image! Copy the file to your own server and use it from there.

jQuery

$.fn.stars = function() {
    return $(this).each(function() {
        // Get the value
        var val = parseFloat($(this).html());
        // Make sure that the value is in 0 - 5 range, multiply to get width
        var size = Math.max(0, (Math.min(5, val))) * 16;
        // Create stars holder
        var $span = $('<span />').width(size);
        // Replace the numerical value with stars
        $(this).html($span);
    });
}

If you want to restrict the stars to only half or quarter star sizes, add one of these rows before the var size row:

val = Math.round(val * 4) / 4; /* To round to nearest quarter */
val = Math.round(val * 2) / 2; /* To round to nearest half */

HTML

<span class="stars">4.8618164</span>
<span class="stars">2.6545344</span>
<span class="stars">0.5355</span>
<span class="stars">8</span>

Usage

$(function() {
    $('span.stars').stars();
});

Output

_{(source: ulmanen.fi)}

Demo

http://www.ulmanen.fi/stuff/stars.php

This will probably suit your needs. With this method you don't have to calculate any three quarter or whatnot star widths, just give it a float and it'll give you your stars.

A small explanation on how the stars are presented might be in order.

The script creates two block level span elements. Both of the spans initally get a size of 80px * 16px and a background image stars.png. The spans are nested, so that the structure of the spans looks like this:

<span class="stars">
    <span></span>
</span>

The outer span gets a background-position of 0 -16px. That makes the gray stars in the outer span visible. As the outer span has height of 16px and repeat-x, it will only show 5 gray stars.

The inner span on the other hand has a background-position of 0 0 which makes only the yellow stars visible.

This would of course work with two separate imagefiles, star_yellow.png and star_gray.png. But as the stars have a fixed height, we can easily combine them into one image. This utilizes the CSS sprite technique.

Now, as the spans are nested, they are automatically overlayed over each other. In the default case, when the width of both spans is 80px, the yellow stars completely obscure the grey stars.

But when we adjust the width of the inner span, the width of the yellow stars decreases, revealing the gray stars.

Accessibility-wise, it would have been wiser to leave the float number inside the inner span and hide it with text-indent: -9999px, so that people with CSS turned off would at least see the floating point number instead of the stars.

Hopefully that made some sense.

Updated 2010/10/22

Now even more compact and harder to understand! Can also be squeezed down to a one liner:

$.fn.stars = function() {
    return $(this).each(function() {
        $(this).html($('<span />').width(Math.max(0, (Math.min(5, parseFloat($(this).html())))) * 16));
    });
}

If you are on Windows, try this:

"C:\Program Files\RStudio\bin\rstudio.exe" http_proxy=http://host:port/

Another way to get the density loaded by the device:

Create values folders for each density

• values (default mdpi)
• values-hdpi
• values-xhdpi
• values-xxhdpi
• values-xxxhdpi

Add a string resource in their respective strings.xml:

<string name="screen_density">MDPI</string>    <!-- ..\res\values\strings.xml -->
<string name="screen_density">HDPI</string>    <!-- ..\res\values-hdpi\strings.xml -->
<string name="screen_density">XHDPI</string>   <!-- ..\res\values-xhdpi\strings.xml -->
<string name="screen_density">XXHDPI</string>  <!-- ..\res\values-xxhdpi\strings.xml -->
<string name="screen_density">XXXHDPI</string> <!-- ..\res\values-xxxhdpi\strings.xml -->

Then simply get the string resource, and you have your density:

String screenDensity = getResources().getString(R.string.screen_density);

If the density is larger than XXXHDPI, it will default to XXXHDPI or if it is lower than HDPI it will default to MDPI

I left out LDPI, because for my use case it isn't necessary.

Keep in mind that as of PHP 5.5.0 the mysql_connect() function is deprecated, and it is completely removed in PHP 7

More info can be found on the php documentation:

Quote:

Warning
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
* mysqli_connect()
* PDO::__construct()

To ans to @Jason 's question, in my bash script, I've dome something like this (for my purpose):

dbPass='xxxxxxxx'
.....
## Connect to the DB
PGPASSWORD=${dbPass} psql -h ${dbHost} -U ${myUsr} -d ${myRdb} -P pager=on --set AUTOCOMMIT=off

The another way of doing it is:

psql --set AUTOCOMMIT=off --set ON_ERROR_STOP=on -P pager=on \
     postgresql://${myUsr}:${dbPass}@${dbHost}/${myRdb}

but you have to be very careful about the password: I couldn't make a password with a ' and/or a : to work in that way. So gave up in the end.

**You can set font size by these properties **

timedisplayLabel= [[UILabel alloc]initWithFrame:CGRectMake(70, 194, 180, 60)];

[timedisplayLabel setTextAlignment:NSTextAlignmentLeft];

[timedisplayLabel setBackgroundColor:[UIColor clearColor]];

[timedisplayLabel setAdjustsFontSizeToFitWidth:YES];

[timedisplayLabel setTextColor:[UIColor blackColor]];

[timedisplayLabel setUserInteractionEnabled:NO];

[timedisplayLabel setFont:[UIFont fontWithName:@"digital-7" size:60]];

timedisplayLabel.layer.shadowColor =[[UIColor whiteColor ]CGColor ];

timedisplayLabel.layer.shadowOffset=(CGSizeMake(0, 0));

timedisplayLabel.layer.shadowOpacity=1;

timedisplayLabel.layer.shadowRadius=3.0;

timedisplayLabel.layer.masksToBounds=NO;

timedisplayLabel.shadowColor=[UIColor darkGrayColor];

timedisplayLabel.shadowOffset=CGSizeMake(0, 2);

Try the following:

$.ajax({
  url: _saveDeviceUrl
, type: 'POST'
, contentType: 'application/json'
, dataType: 'json'
, data: {'myArray': postData}
, success: _madeSave.bind(this)
//, processData: false //Doesn't help
});

using PhpMyAdmin version 4.5.4.1deb2ubuntu2, you can set the variables in /etc/phpmyadmin/config-db.php

so set $dbserver to your server name, e.g. $dbserver='mysql.example.com';

<?php
##
## database access settings in php format
## automatically generated from /etc/dbconfig-common/phpmyadmin.conf
## by /usr/sbin/dbconfig-generate-include
##
## by default this file is managed via ucf, so you shouldn't have to
## worry about manual changes being silently discarded.  *however*,
## you'll probably also want to edit the configuration file mentioned
## above too.
##
$dbuser='phpmyadmin';
$dbpass='P@55w0rd';
$basepath='';
$dbname='phpmyadmin';
$dbserver='localhost';
$dbport='';
$dbtype='mysql';

In pyspark,SparkSql syntax:

where column_n like 'xyz%'

might not work.

Use:

where column_n RLIKE '^xyz' 

This works perfectly fine.

Use react-router-dom library.

From there, import useLocation hook if you're using functional components:

import { useLocation } from 'react-router-dom';

Then append it to a variable:

Const location = useLocation();

You can then use it normally:

location.pathname

P.S: the returned location object has five properties only:

{ hash: "", key: "", pathname: "/" search: "", state: undefined__, }

In case you do no need the exact same width of columns you can try create 5-columns using nesting:

<div class="container">
    <div class="row">
        <div class="col-xs-5">
            <div class="row">
                <div class="col-xs-6 column">Column 1</div>
                <div class="col-xs-6 column">Column 2</div>
            </div>
        </div>
        <div class="col-xs-7">
            <div class="row">
                <div class="col-xs-4 column">Column 3</div>
                <div class="col-xs-4 column">Column 4</div>
                <div class="col-xs-4 column">Column 5</div>
            </div>
        </div>
    </div>
</div>

jsfiddle

The first two columns will have width equal 5/12 * 1/2 ~ 20.83%

The last three columns: 7/12 * 1/3 ~ 19.44%

Such hack gives the acceptable result in many cases and does not require any CSS changes (we're using only the native bootstrap classes).

Not using parameterized queries. They're pretty handy in stopping SQL Injection.

This is a specific example of not sanitizing input data, mentioned in another answer.

I had the same error code when I was running npm run build inside node docker container.

Locally it was working while inside a container I had set option to throw error when there is a warning during compilation while locally it wasn't set. So this error can mean anything that is connected with stopping the process being done by NPM

Wanted to added my 2 pence and a thank you to James Poulose for his original answer it was the only one that worked for my particular project (MVC 5 with the latest version of Bootstrap 3).

This is mostly aimed at beginners, for clarity and to make future edits easier I suggest you add a section at the bottom of your CSS file for your project for example I like to do this:

/* Bootstrap overrides */

.some-class-here {
}

Taking James Poulose's answer above I did this:

/* Bootstrap overrides */   
.navbar-nav > li > a { padding-top: 8px !important; padding-bottom: 5px !important; }
.navbar { min-height: 32px !important; }
.navbar-brand { padding-top: 8px; padding-bottom: 10px; padding-left: 10px; }

I changed the padding-top values to push the text down on my navbar element. You can pretty much override any Bootstrap element like this and its a good way of making changes without screwing up the Boostrap base classes because the last thing you want to do is make a change in there and then lose it when you updated Bootstrap!

Finally for even more separation I like to split up my CSS files and use @import declarations to import your sub-files into one main CSS File for easy management for example:

@import url('css/mysubcssfile.css');

note: if you're pulling in multiple files you need to make sure they load in the right order.

Hope this helps someone.

To add a .net 2.0 Web Service Reference instead of a WCF Service Reference, right-click on your project and click 'Add Service Reference.'

Then click "Advanced.." at the bottom left of the dialog.

Then click "Add Web Reference.." on the bottom left of the next dialog.

Now you can add a regular SOAP web reference like you are looking for.

Since printArea is a jQuery plugin it is not included in jquery.d.ts.

You need to create a jquery.printArea.ts definition file.

If you create a complete definition file for the plugin you may want to submit it to DefinitelyTyped.

Here is a more general Dictionary implementation inspired by this from @dmck

    interface IDictionary<T> {
      add(key: string, value: T): void;
      remove(key: string): void;
      containsKey(key: string): boolean;
      keys(): string[];
      values(): T[];
    }

    class Dictionary<T> implements IDictionary<T> {

      _keys: string[] = [];
      _values: T[] = [];

      constructor(init?: { key: string; value: T; }[]) {
        if (init) {
          for (var x = 0; x < init.length; x++) {
            this[init[x].key] = init[x].value;
            this._keys.push(init[x].key);
            this._values.push(init[x].value);
          }
        }
      }

      add(key: string, value: T) {
        this[key] = value;
        this._keys.push(key);
        this._values.push(value);
      }

      remove(key: string) {
        var index = this._keys.indexOf(key, 0);
        this._keys.splice(index, 1);
        this._values.splice(index, 1);

        delete this[key];
      }

      keys(): string[] {
        return this._keys;
      }

      values(): T[] {
        return this._values;
      }

      containsKey(key: string) {
        if (typeof this[key] === "undefined") {
          return false;
        }

I tried all the solutions, none worked for me (using Swift 4), this is the solution that worked for me, if anyone in future faces the same problem.

let temp = base64String.components(separatedBy: ",")
let dataDecoded : Data = Data(base64Encoded: temp[1], options: 
 .ignoreUnknownCharacters)!

This should do it:

Check out the examples on Wikipedia http://en.wikipedia.org/wiki/Binary_search_algorithm

def binary_search(a, key, imin=0, imax=None):
    if imax is None:
        # if max amount not set, get the total
        imax = len(a) - 1

    while imin <= imax:
        # calculate the midpoint
        mid = (imin + imax)//2
        midval = a[mid]

        # determine which subarray to search
        if midval < key:
            # change min index to search upper subarray
            imin = mid + 1
        elif midval > key:
            # change max index to search lower subarray
            imax = mid - 1
        else:
            # return index number 
            return mid
    raise ValueError

I think it is considered "more pythonic" to just use in when determining if a key already exists, as in

if start not in graph:
    return None

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

I think that this below is accurate and it may help. Feel free to correct it if you find any errors. I'm new at C.

char str[]  

1. array of values of type char, with its own address in memory
2. array of values of type char, with its own address in memory as many consecutive addresses as elements in the array

3. including termination null character '\0' &str, &str[0] and str, all three represent the same location in memory which is address of the first element of the array str

   char *strPtr = &str[0]; //declaration and initialization

alternatively, you can split this in two:

char *strPtr; strPtr = &str[0];

4. strPtr is a pointer to a char
5. strPtr points at array str
6. strPtr is a variable with its own address in memory
7. strPtr is a variable that stores value of address &str[0]
8. strPtr own address in memory is different from the memory address that it stores (address of array in memory a.k.a &str[0])
9. &strPtr represents the address of strPtr itself

I think that you could declare a pointer to a pointer as:

char **vPtr = &strPtr;  

declares and initializes with address of strPtr pointer

Alternatively you could split in two:

char **vPtr;
*vPtr = &strPtr

10. *vPtr points at strPtr pointer
11. *vPtr is a variable with its own address in memory
12. *vPtr is a variable that stores value of address &strPtr
13. final comment: you can not do str++, str address is a const, but you can do strPtr++

You'd better use CSS for this:

td{
    background-color:black;
    color:white;
}
td:hover{
    background-color:white;
    color:black;
}

If you want to use these styles for only a specific set of elements, you should give your td a class (or an ID, if it's the only element which'll have that style).

Example :

HTML

<td class="whiteHover"></td>

CSS

.whiteHover{
    /* Same style as above */
}

Here's a reference on MDN for :hover pseudo class.

Well, those features are specific to a tool that you are using for development in those languages.

You wouldn't have those tools if (for example) you were using notepad to write code. So, maybe you should ask the question for the tool you are using.

For PHP: http://webservices.xml.com/pub/a/ws/2004/03/24/phpws.html

As the title suggests that we want to adjust the size of the labels and not the tick marks I figured that I actually might add something to the question, you need to use the mtext() if you want to specify one of the label sizes, or you can just use par(cex.lab=2) as a simple alternative. Here's a more advanced mtext() example:

set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data=foo,
     yaxt="n", ylab="", 
     xlab="Regular boring x", 
     pch=16,
     col="darkblue")
axis(2,cex.axis=1.2)
mtext("Awesome Y variable", side=2, line=2.2, cex=2)

You may need to adjust the line= option to get the optimal positioning of the text but apart from that it's really easy to use.

First we need to parse the JSON object and then we can add an item.

var str = '{"theTeam":[{"teamId":"1","status":"pending"},
{"teamId":"2","status":"member"},{"teamId":"3","status":"member"}]}';

var obj = JSON.parse(str);
obj['theTeam'].push({"teamId":"4","status":"pending"});
str = JSON.stringify(obj);

Finally we JSON.stringify the obj back to JSON

find ./ -cTime -1 -type f

OR

find ./ -cmin -60 -type f

 static void Main()
    {
        // A.
        // Example strings with multiple whitespaces.
        string s1 = "He saw   a cute\tdog.";
        string s2 = "There\n\twas another sentence.";

        // B.
        // Create the Regex.
        Regex r = new Regex(@"\s+");

        // C.
        // Strip multiple spaces.
        string s3 = r.Replace(s1, @" ");
        Console.WriteLine(s3);

        // D.
        // Strip multiple spaces.
        string s4 = r.Replace(s2, @" ");
        Console.WriteLine(s4);
        Console.ReadLine();
    }

OUTPUT:

He saw a cute dog. There was another sentence. He saw a cute dog.

On newer versions of Symfony2 (using a parameters.yml instead of parameters.ini), you can store objects or arrays instead of key-value pairs, so you can manage your globals this way:

config.yml (edited only once):

# app/config/config.yml
twig:
  globals:
    project: %project%

parameters.yml:

# app/config/parameters.yml
project:
  name:       myproject.com
  version:    1.1.42

And then in a twig file, you can use {{ project.version }} or {{ project.name }}.

Note: I personally dislike adding things to app, just because that's the Symfony's variable and I don't know what will be stored there in the future.

uint32_t is defined in the standard, in

18.4.1 Header <cstdint> synopsis [cstdint.syn]

namespace std {
//...
typedef unsigned integer type uint32_t; // optional
//...
}

uint32 is not, it's a shortcut provided by some compilers (probably as typedef uint32_t uint32) for ease of use.

Try

CREATE TABLE foo LIKE bar;

so the keys and indexes are copied over as, well.

One of the answers in the question referred to by @Z.Bagley gave me the answer. I had to import Renderer2 from @angular/core into my component. Then:

const element = this.renderer.selectRootElement('#input1');

// setTimeout(() => element.focus, 0);
setTimeout(() => element.focus(), 0);

Thank you @MrBlaise for the solution!

Adding this in conf.d fixed this issue for me.

Options +Indexes +FollowSymLinks

It's usually describes as for optional add-on software packagessource, or anything that isn't part of the base system. Only some distributions use it, others simply use /usr/local.

Simple solution that actually renames the elements in-place, not creating a copy, and does a pretty good job of replacing the attributes.

public void RemoveAllNamespaces(ref XElement value)
{
  List<XAttribute> attributesToRemove = new List<XAttribute>();
  foreach (void e_loopVariable in value.DescendantsAndSelf) {
    e = e_loopVariable;
    if (e.Name.Namespace != XNamespace.None) {
      e.Name = e.Name.LocalName;
    }
    foreach (void a_loopVariable in e.Attributes) {
      a = a_loopVariable;
      if (a.IsNamespaceDeclaration) {
        //do not keep it at all
        attributesToRemove.Add(a);
      } else if (a.Name.Namespace != XNamespace.None) {
        e.SetAttributeValue(a.Name.LocalName, a.Value);
        attributesToRemove.Add(a);
      }
    }
  }
  foreach (void a_loopVariable in attributesToRemove) {
    a = a_loopVariable;
    a.Remove();
  }
}

Note: this does not always preserve original attribute order, but I'm sure you could change it to do that pretty easily if it's important to you.

Also note that this also could throw an exception, if you had an XElement attributes that are only unique with the namespace, like:

<root xmlns:ns1="a" xmlns:ns2="b">
    <elem ns1:dupAttrib="" ns2:dupAttrib="" />
</root>

which really seems like an inherent problem. But since the question indicated outputing a String, not an XElement, in this case you could have a solution that would output a valid String that was an invalid XElement.

I also liked jocull's answer using a custom XmlWriter, but when I tried it, it did not work for me. Although it all looks correct, I couldn't tell if the XmlNoNamespaceWriter class had any effect at all; it definitely was not removing the namespaces as I wanted it to.

As you showed convincingly, the font-size: 100%; will not render the same in all browsers. However, you will set your font face in your CSS file, so this will be the same (or a fallback) in all browsers.

I believe font-size: 100%; can be very useful when combining it with em-based design. As this article shows, this will create a very flexible website.

When is this useful? When your site needs to adapt to the visitors' wishes. Take for example an elderly man that puts his default font-size at 24 px. Or someone with a small screen with a large resolution that increases his default font-size because he otherwise has to squint. Most sites would break, but em-based sites are able to cope with these situations.

Refactoring of @srini-beerge's answer which gets the output and the return code

import subprocess
def run_win_cmd(cmd):
    result = []
    process = subprocess.Popen(cmd,
                               shell=True,
                               stdout=subprocess.PIPE,
                               stderr=subprocess.PIPE)
    for line in process.stdout:
        result.append(line)
    errcode = process.returncode
    for line in result:
        print(line)
    if errcode is not None:
        raise Exception('cmd %s failed, see above for details', cmd)

Try:

if not "asdf" == "fdas" echo asdf

That works for me on Windows XP (I get the same error as you for the code you posted).

All you need to give the name attribute to the each button. And you need to address each button press from the PHP script. But be careful to give each button a unique name. Because the PHP script only take care of the name most of the time

Well, this answer has become its own beast. Many new versions, it was getting stupid long. Many thanks to all of the great many contributors to this answer. But, in order to keep it simple for the masses. I archived all the versions/history of this answer's evolution to my github. And started it over clean on StackOverflow here with the newest version. A special thanks goes out to Mike 'Pomax' Kamermans for this version. He gave me the new math.

This function (pSBC) will take a HEX or RGB web color. pSBC can shade it darker or lighter, or blend it with a second color, and can also pass it right thru but convert from Hex to RGB (Hex2RGB) or RGB to Hex (RGB2Hex). All without you even knowing what color format you are using.

This runs really fast, probably the fastest, especially considering its many features. It was a long time in the making. See the whole story on my github. If you want the absolutely smallest and fastest possible way to shade or blend, see the Micro Functions below and use one of the 2-liner speed demons. They are great for intense animations, but this version here is fast enough for most animations.

This function uses Log Blending or Linear Blending. However, it does NOT convert to HSL to properly lighten or darken a color. Therefore, results from this function will differ from those much larger and much slower functions that use HSL.

Features:

• Auto-detects and accepts standard Hex colors in the form of strings. For example: "#AA6622" or "#bb551144".
• Auto-detects and accepts standard RGB colors in the form of strings. For example: "rgb(123,45,76)" or "rgba(45,15,74,0.45)".
• Shades colors to white or black by percentage.
• Blends colors together by percentage.
• Does Hex2RGB and RGB2Hex conversion at the same time, or solo.
• Accepts 3 digit (or 4 digit w/ alpha) HEX color codes, in the form #RGB (or #RGBA). It will expand them. For Example: "#C41" becomes "#CC4411".
• Accepts and (Linear) blends alpha channels. If either the c0 (from) color or the c1 (to) color has an alpha channel, then the returned color will have an alpha channel. If both colors have an alpha channel, then the returned color will be a linear blend of the two alpha channels using the percentage given (just as if it were a normal color channel). If only one of the two colors has an alpha channel, this alpha will just be passed thru to the returned color. This allows one to blend/shade a transparent color while maintaining the transparency level. Or, if the transparency levels should blend as well, make sure both colors have alphas. When shading, it will pass the alpha channel straight thru. If you want basic shading that also shades the alpha channel, then use rgb(0,0,0,1) or rgb(255,255,255,1) as your c1 (to) color (or their hex equivalents). For RGB colors, the returned color's alpha channel will be rounded to 3 decimal places.
• RGB2Hex and Hex2RGB conversions are implicit when using blending. Regardless of the c0 (from) color; the returned color will always be in the color format of the c1 (to) color, if one exists. If there is no c1 (to) color, then pass 'c' in as the c1 color and it will shade and convert whatever the c0 color is. If conversion only is desired, then pass 0 in as the percentage (p) as well. If the c1 color is omitted or a non-string is passed in, it will not convert.
• A secondary function is added to the global as well. pSBCr can be passed a Hex or RGB color and it returns an object containing this color information. Its in the form: {r: XXX, g: XXX, b: XXX, a: X.XXX}. Where .r, .g, and .b have range 0 to 255. And when there is no alpha: .a is -1. Otherwise: .a has range 0.000 to 1.000.
• For RGB output, it outputs rgba() over rgb() when a color with an alpha channel was passed into c0 (from) and/or c1 (to).
• Minor Error Checking has been added. It's not perfect. It can still crash or create jibberish. But it will catch some stuff. Basically, if the structure is wrong in some ways or if the percentage is not a number or out of scope, it will return null. An example: pSBC(0.5,"salt") == null, where as it thinks #salt is a valid color. Delete the four lines which end with return null; to remove this feature and make it faster and smaller.
• Uses Log Blending. Pass true in for l (the 4th parameter) to use Linear Blending.

Micro Functions

If you really want speed and size, you will have to use RGB not HEX. RGB is more straightforward and simple, HEX writes too slow and comes in too many flavors for a simple two-liner (IE. it could be a 3, 4, 6, or 8 digit HEX code). You will also need to sacrifice some features, no error checking, no HEX2RGB nor RGB2HEX. As well, you will need to choose a specific function (based on its function name below) for the color blending math, and if you want shading or blending. These functions do support alpha channels. And when both input colors have alphas it will Linear Blend them. If only one of the two colors has an alpha, it will pass it straight thru to the resulting color. Below are two liner functions that are incredibly fast and small:

const RGB_Linear_Blend=(p,c0,c1)=>{
    var i=parseInt,r=Math.round,P=1-p,[a,b,c,d]=c0.split(","),[e,f,g,h]=c1.split(","),x=d||h,j=x?","+(!d?h:!h?d:r((parseFloat(d)*P+parseFloat(h)*p)*1000)/1000+")"):")";
    return"rgb"+(x?"a(":"(")+r(i(a[3]=="a"?a.slice(5):a.slice(4))*P+i(e[3]=="a"?e.slice(5):e.slice(4))*p)+","+r(i(b)*P+i(f)*p)+","+r(i(c)*P+i(g)*p)+j;
}

const RGB_Linear_Shade=(p,c)=>{
    var i=parseInt,r=Math.round,[a,b,c,d]=c.split(","),P=p<0,t=P?0:255*p,P=P?1+p:1-p;
    return"rgb"+(d?"a(":"(")+r(i(a[3]=="a"?a.slice(5):a.slice(4))*P+t)+","+r(i(b)*P+t)+","+r(i(c)*P+t)+(d?","+d:")");
}

const RGB_Log_Blend=(p,c0,c1)=>{
    var i=parseInt,r=Math.round,P=1-p,[a,b,c,d]=c0.split(","),[e,f,g,h]=c1.split(","),x=d||h,j=x?","+(!d?h:!h?d:r((parseFloat(d)*P+parseFloat(h)*p)*1000)/1000+")"):")";
    return"rgb"+(x?"a(":"(")+r((P*i(a[3]=="a"?a.slice(5):a.slice(4))**2+p*i(e[3]=="a"?e.slice(5):e.slice(4))**2)**0.5)+","+r((P*i(b)**2+p*i(f)**2)**0.5)+","+r((P*i(c)**2+p*i(g)**2)**0.5)+j;
}

const RGB_Log_Shade=(p,c)=>{
    var i=parseInt,r=Math.round,[a,b,c,d]=c.split(","),P=p<0,t=P?0:p*255**2,P=P?1+p:1-p;
    return"rgb"+(d?"a(":"(")+r((P*i(a[3]=="a"?a.slice(5):a.slice(4))**2+t)**0.5)+","+r((P*i(b)**2+t)**0.5)+","+r((P*i(c)**2+t)**0.5)+(d?","+d:")");
}

PT

(P.s. If anyone has the math for another blending method, please share.)

You're missing a FROM and you need to give the subquery an alias.

SELECT COUNT(*) FROM 
(
  SELECT DISTINCT a.my_id, a.last_name, a.first_name, b.temp_val
   FROM dbo.Table_A AS a 
   INNER JOIN dbo.Table_B AS b 
   ON a.a_id = b.a_id
) AS subquery;

This would do it - assuming a Unix-like environment.

MKDIR_P = mkdir -p

.PHONY: directories

all: directories program

directories: ${OUT_DIR}

${OUT_DIR}:
        ${MKDIR_P} ${OUT_DIR}

This would have to be run in the top-level directory - or the definition of ${OUT_DIR} would have to be correct relative to where it is run. Of course, if you follow the edicts of Peter Miller's "Recursive Make Considered Harmful" paper, then you'll be running make in the top-level directory anyway.

I'm playing with this (RMCH) at the moment. It needed a bit of adaptation to the suite of software that I am using as a test ground. The suite has a dozen separate programs built with source spread across 15 directories, some of it shared. But with a bit of care, it can be done. OTOH, it might not be appropriate for a newbie.

As noted in the comments, listing the 'mkdir' command as the action for 'directories' is wrong. As also noted in the comments, there are other ways to fix the 'do not know how to make output/debug' error that results. One is to remove the dependency on the the 'directories' line. This works because 'mkdir -p' does not generate errors if all the directories it is asked to create already exist. The other is the mechanism shown, which will only attempt to create the directory if it does not exist. The 'as amended' version is what I had in mind last night - but both techniques work (and both have problems if output/debug exists but is a file rather than a directory).

The instanceof-operator is called is in Dart. The spec isn't exactly friendly to a casual reader, so the best description right now seems to be http://www.dartlang.org/articles/optional-types/.

Here's an example:

class Foo { }

main() {
  var foo = new Foo();
  if (foo is Foo) {
    print("it's a foo!");
  }
}

In my case (dealing with my assemblies loaded [as file] into Outlook):

typeof(OneOfMyTypes).Assembly.CodeBase

Note the use of CodeBase (not Location) on the Assembly. Others have pointed out alternative methods of locating the assembly.

I had some problems with the insertion process just like you, so here is the code how I have solved the problem:

void add_by_position(int data, int pos)
  {
        link *node = new link;
        link *linker = head;

        node->data = data;
        for (int i = 0; i < pos; i++){
            linker = linker->next;
        }
        node->next = linker;
        linker = head;
        for (int i = 0; i < pos - 1; i++){
            linker = linker->next;
        }
        linker->next = node;
        boundaries++;
    }

Use fs.writeFileSync inside the try/catch block as below.

`var fs = require('fs');
 try {
     const file = fs.writeFileSync(ASIN + '.json', JSON.stringify(results))
     console.log("JSON saved");
     return results;
 } catch (error) {
   console.log(err);
  }`

How about this:

$(this).css('background-color', '#FFFFFF');

set -x

    echo 'crap, no foo'

Change foo to vi to get the other condition to fire.

It makes sure that the returned object (which is an RValue at that point) can't be modified. This makes sure the user can't do thinks like this:

myFunc() = Object(...);

That would work nicely if myFunc returned by reference, but is almost certainly a bug when returned by value (and probably won't be caught by the compiler). Of course in C++11 with its rvalues this convention doesn't make as much sense as it did earlier, since a const object can't be moved from, so this can have pretty heavy effects on performance.

Just in case someone else was struggeling with the accepted answer:

There are different OnCheckedChangeListener-Interfaces. I added to first one to see if a CheckBox was changed.

import android.widget.CompoundButton.OnCheckedChangeListener;

vs

import android.widget.RadioGroup.OnCheckedChangeListener;

When adding the snippet from Ricky I had errors:

The method setOnCheckedChangeListener(RadioGroup.OnCheckedChangeListener) in the type RadioGroup is not applicable for the arguments (new CompoundButton.OnCheckedChangeListener(){})

Can be fixed with answer from Ali :

new RadioGroup.OnCheckedChangeListener()

Set the name attribute of your form to "theForm" and your code will work.

If you are using android studio use simple steps:

• Run your project

• Click on Gradle menu

• Expand Gradle task tree

• Click on android-> signingReport

If there is nothing displayed(android studio 2.2) then

Click on Toggle tasks execution/text mode from Run bar

Use this regular expression to match ten digits only:

@"^\d{10}$"

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

@"\d{10}"

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

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

There is no function overloading in Python, meaning that you can't have multiple functions with the same name but different arguments.

In your code example, you're not overloading __init__(). What happens is that the second definition rebinds the name __init__ to the new method, rendering the first method inaccessible.

As to your general question about constructors, Wikipedia is a good starting point. For Python-specific stuff, I highly recommend the Python docs.

The variable name you're looking for is ansible_ssh_private_key_file.

You should set it at 'vars' level:

• in the inventory file:

  myHost ansible_ssh_private_key_file=~/.ssh/mykey1.pem
  myOtherHost ansible_ssh_private_key_file=~/.ssh/mykey2.pem
  

• in the host_vars:

  # hosts_vars/myHost.yml
  ansible_ssh_private_key_file: ~/.ssh/mykey1.pem
  
  # hosts_vars/myOtherHost.yml
  ansible_ssh_private_key_file: ~/.ssh/mykey2.pem
  

• in a group_vars file if you use the same key for a group of hosts

• in the vars section of your play:

  - hosts: myHost
    remote_user: ubuntu
    vars_files:
      - vars.yml
    vars:
      ansible_ssh_private_key_file: "{{ key1 }}"
    tasks:
      - name: Echo a hello message
        command: echo hello
  

Inventory documentation

aca definis los anchos

I presume that you're talking about bash strings. There are different types of strings which have a different set of requirements for escaping. eg. Single quotes strings are different from double quoted strings.

The best reference is the Quoting section of the bash manual.

It explains which characters needs escaping. Note that some characters may need escaping depending on which options are enabled such as history expansion.

The default expiry_date for google oauth2 access token is 1 hour. The expiry_date is in the Unix epoch time in milliseconds. If you want to read this in human readable format then you can simply check it here..Unix timestamp to human readable time

Here's a Counter answer for the simplest case.

This is shorter than the one above that does two-way diffs because it only does exactly what the question asks: generate a list of what's in the first list but not the second.

from collections import Counter

lst1 = ['One', 'Two', 'Three', 'Four']
lst2 = ['One', 'Two']

c1 = Counter(lst1)
c2 = Counter(lst2)
diff = list((c1 - c2).elements())

Alternatively, depending on your readability preferences, it makes for a decent one-liner:

diff = list((Counter(lst1) - Counter(lst2)).elements())

Output:

['Three', 'Four']

Note that you can remove the list(...) call if you are just iterating over it.

Because this solution uses counters, it handles quantities properly vs the many set-based answers. For example on this input:

lst1 = ['One', 'Two', 'Two', 'Two', 'Three', 'Three', 'Four']
lst2 = ['One', 'Two']

The output is:

['Two', 'Two', 'Three', 'Three', 'Four']

Looks like maven is not present in your PATH. Add the absolute maven home\bin location to your PATH.

Syntactically, this line makes no sense:

invest(initial_amount,top_company(5,year,year+1)) = subsequent_amount

You are attempting to assign a value to a function call, as the error says. What are you trying to accomplish? If you're trying set subsequent_amount to the value of the function call, switch the order:

subsequent_amount = invest(initial_amount,top_company(5,year,year+1))

Use something such as the following:

if (String.IsNullOrEmpty(MaterialTextBox.Text)) 

What about using the CallByName of the Microsoft.VisualBasic namespace (Microsoft.VisualBasic.dll)? It uses reflection to get properties, fields, and methods of normal objects, COM objects, and even dynamic objects.

using Microsoft.VisualBasic;
using Microsoft.VisualBasic.CompilerServices;

and then

Versioned.CallByName(this, "method/function/prop name", CallType.Get).ToString();

I had a similar problem on Internet Explorer, and got the same error number. The culprit was an HTML comment. I know it sounds unbelievable, so here is the story.

I saw a series of 6 articles on the Internet. I liked them, so I decided to download the 6 Web-Pages and store them on my Hard Drive. At the top of each page, was a couple of HTML <a> Tags, that would allow you to go to the next article or the previous article. So I changed the href attribute to point to the next folder on my Hard Drive, instead of the next URL on the Internet.

After all of the links had been re-directed, the Browser refused to display any of the Web-Pages when I clicked on the Links. The message in the Console was the Error Number that was mentioned at the top of this page.

However, the real problem was a Comment. Whenever you download a Web-Page using Google Chrome, the Chrome Browser inserts a Comment at the very top of the page that includes the URL of the location that you got the Web-Page from. After I removed the Comment at the top of each one of the 6 Pages, all of the Links worked fine ( although I continued to get the same Error Message in the Console. )

A simple fix for this is to install the Google Cast extension. If you don't have a Chromecast, or don't want to use the extension, no problem; just don't use the extension.

I am not sure what you really want here. If you want to see the .NET framework source code, you may try Netmassdownloader. It's free.

If you want to see any assembly's code (not just .NET), you can use ReSharper. Although it's not free.

Since the question is tagged as JQuery:

If you are also using JQuery UI you can use $.datepicker.formatDate():

$.datepicker.formatDate('yy/mm/dd', new Date());

Lambdas are actually very powerful constructs that stem from ideas in functional programming, and it is something that by no means will be easily revised, redefined or removed in the near future of Python. They help you write code that is more powerful as it allows you to pass functions as parameters, thus the idea of functions as first-class citizens.

Lambdas do tend to get confusing, but once a solid understanding is obtained, you can write clean elegant code like this:

squared = map(lambda x: x*x, [1, 2, 3, 4, 5])

The above line of code returns a list of the squares of the numbers in the list. Ofcourse, you could also do it like:

def square(x):
    return x*x

squared = map(square, [1, 2, 3, 4, 5])

It is obvious the former code is shorter, and this is especially true if you intend to use the map function (or any similar function that takes a function as a parameter) in only one place. This also makes the code more intuitive and elegant.

Also, as @David Zaslavsky mentioned in his answer, list comprehensions are not always the way to go especially if your list has to get values from some obscure mathematical way.

From a more practical standpoint, one of the biggest advantages of lambdas for me recently has been in GUI and event-driven programming. If you take a look at callbacks in Tkinter, all they take as arguments are the event that triggered them. E.g.

def define_bindings(widget):
    widget.bind("<Button-1>", do-something-cool)

def do-something-cool(event):
    #Your code to execute on the event trigger

Now what if you had some arguments to pass? Something as simple as passing 2 arguments to store the coordinates of a mouse-click. You can easily do it like this:

def main():
    # define widgets and other imp stuff
    x, y = None, None
    widget.bind("<Button-1>", lambda event: do-something-cool(x, y))

def do-something-cool(event, x, y):
    x = event.x
    y = event.y
    #Do other cool stuff

Now you can argue that this can be done using global variables, but do you really want to bang your head worrying about memory management and leakage especially if the global variable will just be used in one particular place? That would be just poor programming style.

In short, lambdas are awesome and should never be underestimated. Python lambdas are not the same as LISP lambdas though (which are more powerful), but you can really do a lot of magical stuff with them.

I would recommend to use ampersand to have an access to named blocks within a function. Following the recommendations given in this article you can write something like this (this is a real scrap from my working program):

  # Returns a valid hash for html form select element, combined of all entities
  # for the given +model+, where only id and name attributes are taken as
  # values and keys correspondingly. Provide block returning boolean if you
  # need to select only specific entities.
  #
  # * *Args*    :
  #   - +model+ -> ORM interface for specific entities'
  #   - +&cond+ -> block {|x| boolean}, filtering entities upon iterations
  # * *Returns* :
  #   - hash of {entity.id => entity.name}
  #
  def make_select_list( model, &cond )
    cond ||= proc { true } # cond defaults to proc { true }
    # Entities filtered by cond, followed by filtration by (id, name)
    model.all.map do |x|
      cond.( x ) ? { x.id => x.name } : {}
    end.reduce Hash.new do |memo, e| memo.merge( e ) end
  end

Afterwerds, you can call this function like this:

@contests = make_select_list Contest do |contest|
  logged_admin? or contest.organizer == @current_user
end

If you don't need to filter your selection, you simply omit the block:

@categories = make_select_list( Category ) # selects all categories

So much for the power of Ruby blocks.

(change) event bound to classical input change event.

https://developer.mozilla.org/en-US/docs/Web/Events/change

You can use (change) event even if you don't have a model at your input as

<input (change)="somethingChanged()">

(ngModelChange) is the @Output of ngModel directive. It fires when the model changes. You cannot use this event without ngModel directive.

https://github.com/angular/angular/blob/master/packages/forms/src/directives/ng_model.ts#L124

As you discover more in the source code, (ngModelChange) emits the new value.

https://github.com/angular/angular/blob/master/packages/forms/src/directives/ng_model.ts#L169

So it means you have ability of such usage:

<input (ngModelChange)="modelChanged($event)">

modelChanged(newObj) {
    // do something with new value
}

Basically, it seems like there is no big difference between two, but ngModel events gains the power when you use [ngValue].

  <select [(ngModel)]="data" (ngModelChange)="dataChanged($event)" name="data">
      <option *ngFor="let currentData of allData" [ngValue]="currentData">
          {{data.name}}
      </option>
  </select>

dataChanged(newObj) {
    // here comes the object as parameter
}

assume you try the same thing without "ngModel things"

<select (change)="changed($event)">
    <option *ngFor="let currentData of allData" [value]="currentData.id">
        {{data.name}}
    </option>
</select>

changed(e){
    // event comes as parameter, you'll have to find selectedData manually
    // by using e.target.data
}

If you are copy-pasting code into R, it sometimes won't accept some special characters such as "~" and will appear instead as a "?". So if a certain character is giving an error, make sure to use your keyboard to enter the character, or find another website to copy-paste from if that doesn't work.

Smallest memory? This isn't smallest, but is a step in the right direction.

class PrimeDictionary {
    BitArray bits;

    public PrimeDictionary(int n) {
        bits = new BitArray(n + 1);
        for (int i = 0; 2 * i + 3 <= n; i++) {
            bits.Set(i, CheckPrimality(2 * i + 3));
        }
    }

    public PrimeDictionary(IEnumerable<int> primes) {
        bits = new BitArray(primes.Max());
        foreach(var prime in primes.Where(p => p != 2)) {
            bits.Set((prime - 3) / 2, true);
        }
    }

    public bool IsPrime(int k) {
        if (k == 2) {
            return true;
        }
        if (k % 2 == 0) {
            return false;
        }
        return bits[(k - 3) / 2];
    }
}

Of course, you have to specify the definition of CheckPrimality.

Mail chimp have got quite a nice article on what not to do. ( I know it sounds the wrong way round for what you want)

http://kb.mailchimp.com/article/common-html-email-coding-mistakes

In general all the things that you have learnt that are bad practise for web design seem to be the only option for html email.

The basics are:

• Have absolute paths for images (eg. https://stackoverflow.com/random-image.png)
• Use tables for layout (never thought I'd recommend that!)
• Use inline styles (and old school css too, at the very most 2.1, box-shadow won't work for instance ;) )

Just test in as many email clients as you can get your hands on, or use Litmus as someone else suggested above! (credit to Jim)

EDIT :

Mail chimp have done a great job by making this tool available to the community.

It applies your CSS classes to your html elements inline for you!

Another point to mention is that you should ensure that your equality function is as you expect. You should override the equals method to set up what properties of your object have to match for two instances to be considered equal.

Then you can just do mylist.contains(item)

I suggest using Vladimir Keleshev's pep257 Python program to check your docstrings against PEP-257 and the Numpy Docstring Standard for describing parameters, returns, etc.

pep257 will report divergence you make from the standard and is called like pylint and pep8.

There is an easier way than all of the above; You can use the PY_PYTHON environment variable. From inside the cmd.exe shell;

For the latest version of Python 2

set PY_PYTHON=2

For the latest version of Python 3

set PY_PYTHON=3

If you want it to be permanent, set it in the control panel. Or use setx instead of set in the cmd.exe shell.

My Comments:

When I see the output, the output is mixed with One, Two, Three which are the thread names and they run simultaneously. I am not sure when you say thread is not running by main method.

Not sure if I understood your question or not. But I m putting my answer what I could understand, hope it can help you.

1) Then you created the object, it called the constructor, in construct it has start method which started the thread and executed the contents written inside run() method.

So as you created 3 objects (3 threads - one, two, three), all 3 threads started executing simultaneously.

2) Join and Synchronization They are 2 different things, Synchronization is when there are multiple threads sharing a common resource and one thread should use that resource at a time. E.g. Threads such as DepositThread, WithdrawThread etc. do share a common object as BankObject. So while DepositThread is running, the WithdrawThread will wait if they are synchronized. wait(), notify(), notifyAll() are used for inter-thread communication. Plz google to know more.

about Join(), it is when multiple threads are running, but you join. e.g. if there are two thread t1 and t2 and in multi-thread env they run, the output would be: t1-0 t2-0 t1-1 t2-1 t1-2 t2-2

and we use t1.join(), it would be: t1-0 t1-1 t1-2 t2-0 t2-1 t2-2

This is used in realtime when sometimes you don't mix up the thread in certain conditions and one depends another to be completed (not in shared resource), so you can call the join() method.

Only restart the SID services. For example you SID name = orcl then all the services which related to orcl should be restart then you problem will be solved

If multiple criteria use countifs

=countifs(A1:A10,">""",B1:B10,">""")

The " >"" " looks at the greater than being empty. This formula looks for two criteria and neither column can be empty on the same row for it to count. If just counting one column do this with the one criteria (i.e. Use everything before B1:B10 not including the comma)

Because constants in Ruby aren't meant to be changed, Ruby discourages you from assigning to them in parts of code which might get executed more than once, such as inside methods.

Under normal circumstances, you should define the constant inside the class itself:

class MyClass
  MY_CONSTANT = "foo"
end

MyClass::MY_CONSTANT #=> "foo"

If for some reason though you really do need to define a constant inside a method (perhaps for some type of metaprogramming), you can use const_set:

class MyClass
  def my_method
    self.class.const_set(:MY_CONSTANT, "foo")
  end
end

MyClass::MY_CONSTANT
#=> NameError: uninitialized constant MyClass::MY_CONSTANT

MyClass.new.my_method
MyClass::MY_CONSTANT #=> "foo"

Again though, const_set isn't something you should really have to resort to under normal circumstances. If you're not sure whether you really want to be assigning to constants this way, you may want to consider one of the following alternatives:

Class variables

Class variables behave like constants in many ways. They are properties on a class, and they are accessible in subclasses of the class they are defined on.

The difference is that class variables are meant to be modifiable, and can therefore be assigned to inside methods with no issue.

class MyClass
  def self.my_class_variable
    @@my_class_variable
  end
  def my_method
    @@my_class_variable = "foo"
  end
end
class SubClass < MyClass
end

MyClass.my_class_variable
#=> NameError: uninitialized class variable @@my_class_variable in MyClass
SubClass.my_class_variable
#=> NameError: uninitialized class variable @@my_class_variable in MyClass

MyClass.new.my_method
MyClass.my_class_variable #=> "foo"
SubClass.my_class_variable #=> "foo"

Class attributes

Class attributes are a sort of "instance variable on a class". They behave a bit like class variables, except that their values are not shared with subclasses.

class MyClass
  class << self
    attr_accessor :my_class_attribute
  end
  def my_method
    self.class.my_class_attribute = "blah"
  end
end
class SubClass < MyClass
end

MyClass.my_class_attribute #=> nil
SubClass.my_class_attribute #=> nil

MyClass.new.my_method
MyClass.my_class_attribute #=> "blah"
SubClass.my_class_attribute #=> nil

SubClass.new.my_method
SubClass.my_class_attribute #=> "blah"

Instance variables

And just for completeness I should probably mention: if you need to assign a value which can only be determined after your class has been instantiated, there's a good chance you might actually be looking for a plain old instance variable.

class MyClass
  attr_accessor :instance_variable
  def my_method
    @instance_variable = "blah"
  end
end

my_object = MyClass.new
my_object.instance_variable #=> nil
my_object.my_method
my_object.instance_variable #=> "blah"

MyClass.new.instance_variable #=> nil

I was facing some difficulties with an environment variable that is with custom name (not with container name /port convention for KAPACITOR_BASE_URL and KAPACITOR_ALERTS_ENDPOINT). If we give service name in this case it wouldn't resolve the ip as

Just my 2 cents, hope it helps someone somewhere.

Label is an inline element - so, unless a width is defined, its width is exact the same which the letters span. Your div element is a block element so its width is by default 100%.

You will have to place the text-align: right; on the div element in your case, or applying display: block; to your label

Another option is to set a width for each label and then use text-align. The display: block method will not be necessary using this.

This code may be helpful

L ={x, y, z}
T= ((0,"c"),(1,"d"),(2,"e"),(3,"f"),)
List2=[]
for t in T :
if t[0] in L :
    List2.append(t[1])
    break;

System.String is a reference type and already "nullable".

Nullable<T> and the ? suffix are for value types such as Int32, Double, DateTime, etc.

Yes you can!

As of November 2016, Microsoft now has integrated .NET Core in it's official .NET Site

They even have a new Visual Studio app that runs on MacOS

One thing that could have happened:

• 1: you create your serialized data with a given library A (version X)
• 2: you then try to read this data with the same library A (but version Y)

Hence, at compile time for the version X, the JVM will generate a first Serial ID (for version X) and it will do the same with the other version Y (another Serial ID).

When your program tries to de-serialize the data, it can't because the two classes do not have the same Serial ID and your program have no guarantee that the two Serialized objects correspond to the same class format.

Assuming you changed your constructor in the mean time and this should make sense to you.

use this to convert string to datetime:

Datetime DT = DateTime.ParseExact(STRDATE,"dd/MM/yyyy",System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat)

Check out the node.js module list

• node-mysql — A node.js module implementing the MySQL protocol
• node-mysql2 — Yet another pure JS async driver. Pipelining, prepared statements.
• node-mysql-libmysqlclient — MySQL asynchronous bindings based on libmysqlclient

node-mysql looks simple enough:

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'example.org',
  user     : 'bob',
  password : 'secret',
});

connection.connect(function(err) {
  // connected! (unless `err` is set)
});

Queries:

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  // Neat!
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'

In case your data are stored as a Pandas DataFrame, you can use remove_stopwords from textero that use the NLTK stopwords list by default.

import pandas as pd

df['text_without_stopwords'] = hero.remove_stopwords(df['text'])

Based on some of the answers here, I have written a CustomConstructorResolver for use in a current project, and I thought it might help somebody else.

It supports the following resolution mechanisms, all configurable:

• Select a single private constructor so you can define one private constructor without having to mark it with an attribute.
• Select the most specific private constructor so you can have multiple overloads, still without having to use attributes.
• Select the constructor marked with an attribute of a specific name - like the default resolver, but without a dependency on the Json.Net package because you need to reference Newtonsoft.Json.JsonConstructorAttribute.

public class CustomConstructorResolver : DefaultContractResolver
{
    public string ConstructorAttributeName { get; set; } = "JsonConstructorAttribute";
    public bool IgnoreAttributeConstructor { get; set; } = false;
    public bool IgnoreSinglePrivateConstructor { get; set; } = false;
    public bool IgnoreMostSpecificConstructor { get; set; } = false;

    protected override JsonObjectContract CreateObjectContract(Type objectType)
    {
        var contract = base.CreateObjectContract(objectType);

        // Use default contract for non-object types.
        if (objectType.IsPrimitive || objectType.IsEnum) return contract;

        // Look for constructor with attribute first, then single private, then most specific.
        var overrideConstructor = 
               (this.IgnoreAttributeConstructor ? null : GetAttributeConstructor(objectType)) 
            ?? (this.IgnoreSinglePrivateConstructor ? null : GetSinglePrivateConstructor(objectType)) 
            ?? (this.IgnoreMostSpecificConstructor ? null : GetMostSpecificConstructor(objectType));

        // Set override constructor if found, otherwise use default contract.
        if (overrideConstructor != null)
        {
            SetOverrideCreator(contract, overrideConstructor);
        }

        return contract;
    }

    private void SetOverrideCreator(JsonObjectContract contract, ConstructorInfo attributeConstructor)
    {
        contract.OverrideCreator = CreateParameterizedConstructor(attributeConstructor);
        contract.CreatorParameters.Clear();
        foreach (var constructorParameter in base.CreateConstructorParameters(attributeConstructor, contract.Properties))
        {
            contract.CreatorParameters.Add(constructorParameter);
        }
    }

    private ObjectConstructor<object> CreateParameterizedConstructor(MethodBase method)
    {
        var c = method as ConstructorInfo;
        if (c != null)
            return a => c.Invoke(a);
        return a => method.Invoke(null, a);
    }

    protected virtual ConstructorInfo GetAttributeConstructor(Type objectType)

        var constructors = objectType
            .GetConstructors(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic)
            .Where(c => c.GetCustomAttributes().Any(a => a.GetType().Name == this.ConstructorAttributeName)).ToList();

        if (constructors.Count == 1) return constructors[0];
        if (constructors.Count > 1)
            throw new JsonException($"Multiple constructors with a {this.ConstructorAttributeName}.");

        return null;
    }

    protected virtual ConstructorInfo GetSinglePrivateConstructor(Type objectType)
    {
        var constructors = objectType

Feedback appreciated.

Why don't you try converting its type from a tuple to a list and vice versa.

level1 = (
     (1,1,1,1,1,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,1,1,1,1,1))

print(level1)

level1 = list(level1)

print(level1)

level1 = tuple(level1)

print(level1)

I finally got the corners to stay. This is c#, Xamarin.Android

Just wrap the textarea with the label and set the textarea style to

vertical-align: middle;

Here is some magic for all textareas on the page:)

    }
</style>

<label>Blah blah blah Description: <textarea>dura bura</textarea></label>

Change your Google Services version from your build.gradle:

dependencies {
  classpath 'com.google.gms:google-services:4.2.0'
}

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

dictionary['key'] = dictionary.get('key', []) + list_to_append

"creating an instance of a class" how about, "you are taking a class and making a new variable of that class that WILL change depending on an input that changes"

Class in the library called Nacho

variable Libre to hold the "instance" that will change

Nacho Libre = new Nacho(Variable, Scanner Input, or whatever goes here, This is the place that accepts the changes then puts the value in "Libre" on the left side of the equals sign (you know "Nacho Libre = new Nacho(Scanner.in)" "Nacho Libre" is on the left of the = (that's not tech talk, that's my way of explaining it)

I think that is better than saying "instance of type" or "instance of class". Really the point is it just needs to be detailed out more.... "instance of type or class" is not good enough for the beginner..... wow, its like a tongue twister and your brain cannot focus on tongue twisters very well.... that "instance" word is very annoying and the mere sound of it drives me nuts.... it begs for more detail.....it begs to be broken down better. I had to google what "instance" meant just to get my bearings straight..... try saying "instance of class" to your grandma.... yikes!

I changed 3 things and then it works:

1. There is a column of spaces, I removed them
2. Changed the line break from windows CRLF to linux LF
3. Removed the empty line at the end.

For this you have to set AUTO_INCREMENT value

ALTER TABLE tablename AUTO_INCREMENT = <INITIAL_VALUE>

Example

ALTER TABLE tablename AUTO_INCREMENT = 101

In ASP.NET, when should I use Session.Clear() rather than Session.Abandon()?

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want him to relogin for example) and reset all his session specific data.

What is the difference between Session.Abandon() and Session.Clear()

Clear - Removes all keys and values from the session-state collection.

Abandon - removes all the objects stored in a Session. If you do not call the Abandon method explicitly, the server removes these objects and destroys the session when the session times out. It also raises events like Session_End.

Session.Clear can be compared to removing all books from the shelf, while Session.Abandon is more like throwing away the whole shelf.

...

Generally, in most cases you need to use Session.Clear. You can use Session.Abandon if you are sure the user is going to leave your site.

So back to the differences:

• Abandon raises Session_End request.
• Clear removes items immediately, Abandon does not.
• Abandon releases the SessionState object and its items so it can garbage collected.
• Clear keeps SessionState and resources associated with it.

Session.Clear() or Session.Abandon() ?

You use Session.Clear() when you don't want to end the session but rather just clear all the keys in the session and reinitialize the session.

Session.Clear() will not cause the Session_End eventhandler in your Global.asax file to execute.

But on the other hand Session.Abandon() will remove the session altogether and will execute Session_End eventhandler.

Session.Clear() is like removing books from the bookshelf

Session.Abandon() is like throwing the bookshelf itself.

Question

I check on some sessions if not equal null in the page load. if one of them equal null i wanna to clear all the sessions and redirect to the login page?

Answer

If you want the user to login again, use Session.Abandon.

create a global temp table with a GUID in the name dynamically. Then you can work with it in your code, via dyn sql, without worry that another process calling same sproc will use it. This is useful when you dont know what to expect from the underlying selected table each time it runs so you cannot created a temp table explicitly beforehand. ie - you need to use SELECT * INTO syntax

DECLARE @TmpGlobalTable varchar(255) = 'SomeText_' + convert(varchar(36),NEWID())

-- select @TmpGlobalTable 

-- build query
    SET @Sql = 
        'SELECT * INTO [##' + @TmpGlobalTable + '] FROM SomeTable'
EXEC (@Sql)
EXEC ('SELECT * FROM [##' + @TmpGlobalTable + '] ')
EXEC ('DROP TABLE [##' + @TmpGlobalTable + ']')
PRINT 'Dropped Table ' + @TmpGlobalTable 

Another option, if you prefer, would be to get the DOM element from the jQuery object and use standard DOM accessors on it:

$("#myElement")[0].title = "new title value";

The "jQuery way", as mentioned by others, is to use the attr() method. See the API documentation for attr() here.

Throwing another answer into the ring. If you're trying to use CSS variables, then it will quietly fail.

@media screen and (max-device-width: var(--breakpoint-small)) {}

CSS variables don't work in media queries (by design).

It means that there have been other commits pushed to the remote repository that differ from your commits. You can usually solve this with a

git pull

before you push

Ultimately, "fast-forward" means that the commits can be applied directly on top of the working tree without requiring a merge.

Thorbjørn Ravn Andersen answered for most of the data types. Since there was a heated discussion about array,

Quoting from the jls spec http://docs.oracle.com/javase/specs/jls/se7/html/jls-4.html#jls-4.12.5 "array component is initialized with a default value when it is created"

I think irrespective of whether array is local or instance or class variable it will with default values

Use ALTER:

ALTER TABLE `tbl_Country` DROP COLUMN `column_name`;

I've found DebugBar.

Not as good as Firebug, but close.

printing a list can also cause this problem (im new in python, so it confused me a bit too):

>>>myList = ['\\']
>>>print myList
['\\']
>>>print ''.join(myList)
\ 

similarly:

>>>myList = ['\&']
>>>print myList
['\\&']
>>>print ''.join(myList)

In addition to @Bruno's answer, you need to supply the -name for alias, otherwise Tomcat will throw Alias name tomcat does not identify a key entry error

Sample Command: openssl pkcs12 -export -in localhost.crt -inkey localhost.key -out localhost.p12 -name localhost

If your are on windows you can do it this way :

1. In your project root directory, Create file run.bat
2. Add your command with your choice of configurations in this file. For Example

ng serve --host 192.168.1.2 --open

3. Now you can click and open this file whenever you want to serve.

This not standard way but comfortable to use (which I feel).

Here's a batch file, called base64encode.bat, that encodes base64.

@echo off
if not "%1" == "" goto :arg1exists
echo usage: base64encode input-file [output-file]
goto :eof
:arg1exists
set base64out=%2
if "%base64out%" == "" set base64out=con 
(
  set base64tmp=base64.tmp
  certutil -encode "%1" %base64tmp% > nul
  findstr /v /c:- %base64tmp%
  erase %base64tmp%
) > %base64out%

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

Overriding -textRectForBounds: will only change the inset of the placeholder text. To change the inset of the editable text, you need to also override -editingRectForBounds:

// placeholder position
- (CGRect)textRectForBounds:(CGRect)bounds {
     return CGRectInset(bounds, 10, 10);
}

// text position
- (CGRect)editingRectForBounds:(CGRect)bounds {
     return CGRectInset(bounds, 10, 10);
}

I had same issue, and for me, I was trying to use an IP Address instead of computer name. Just adding this as one more potential solution for people finding this down the road.

You sure can.

The easiest way to see how you might do this is to browse to the aspx page you want to post to. Then save the source of that page as HTML. Change the action of the form on your new html page to point back to the aspx page you originally copied it from.

Add value tags to your form fields and put the data you want in there, then open the page and hit the submit button.

Be careful,

jQuery.validator.addMethod("lettersonly", function(value, element) 
{
return this.optional(element) || /^[a-z," "]+$/i.test(value);
}, "Letters and spaces only please"); 

[a-z, " "] by adding the comma and quotation marks, you are allowing spaces, commas and quotation marks into the input box.

For spaces + text, just do this:

jQuery.validator.addMethod("lettersonly", function(value, element) 
{
return this.optional(element) || /^[a-z ]+$/i.test(value);
}, "Letters and spaces only please");

[a-z ] this allows spaces aswell as text only.

............................................................................

also the message "Letters and spaces only please" is not required, if you already have a message in messages:

messages:{
        firstname:{
        required: "Enter your first name",
        minlength: jQuery.format("Enter at least (2) characters"),
        maxlength:jQuery.format("First name too long more than (80) characters"),
        lettersonly:jQuery.format("letters only mate")
        },

In case you get the error "No 'Access-Control-Allow-Origin' header is present on the requested resource." Specifically for PUT and DELETE requests, you could try to disable WebDAV on IIS.

Apparently, the WebDAVModule is enabled by default and is disabling PUT and DELETE requests by default.

To disable the WebDAVModule, add this to your web.config:

<system.webServer>
  <modules runAllManagedModulesForAllRequests="false">

There are legitimate technical reasons to want a generalized solution to the problem of bash alias not having a mechanism to take a reposition arbitrary arguments. One reason is if the command you wish to execute would be adversely affected by the changes to the environment that result from executing a function. In all other cases, functions should be used.

What recently compelled me to attempt a solution to this is that I wanted to create some abbreviated commands for printing the definitions of variables and functions. So I wrote some functions for that purpose. However, there are certain variables which are (or may be) changed by a function call itself. Among them are:

FUNCNAME BASH_SOURCE BASH_LINENO BASH_ARGC BASH_ARGV

The basic command I had been using (in a function) to print variable defns. in the form output by the set command was:

sv () { set | grep --color=never -- "^$1=.*"; }

E.g.:

> V=voodoo
sv V
V=voodoo

Problem: This won't print the definitions of the variables mentioned above as they are in the current context, e.g., if in an interactive shell prompt (or not in any function calls), FUNCNAME isn't defined. But my function tells me the wrong information:

> sv FUNCNAME
FUNCNAME=([0]="sv")

One solution I came up with has been mentioned by others in other posts on this topic. For this specific command to print variable defns., and which requires only one argument, I did this:

alias asv='(grep -- "^$(cat -)=.*" <(set)) <<<'

Which gives the correct output (none), and result status (false):

> asv FUNCNAME
> echo $?
1

However, I still felt compelled to find a solution that works for arbitrary numbers of arguments.

A General Solution To Passing Arbitrary Arguments To A Bash Aliased Command:

# (I put this code in a file "alias-arg.sh"):

# cmd [arg1 ...] – an experimental command that optionally takes args,
# which are printed as "cmd(arg1 ...)"
#
# Also sets global variable "CMD_DONE" to "true".
#
cmd () { echo "cmd($@)"; declare -g CMD_DONE=true; }

# Now set up an alias "ac2" that passes to cmd two arguments placed
# after the alias, but passes them to cmd with their order reversed:
#
# ac2 cmd_arg2 cmd_arg1 – calls "cmd" as: "cmd cmd_arg1 cmd_arg2"
#
alias ac2='
    # Set up cmd to be execed after f() finishes:
    #
    trap '\''cmd "${CMD_ARGV[1]}" "${CMD_ARGV[0]}"'\'' SIGUSR1;
    #        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    #       (^This is the actually execed command^)
    #
    # f [arg0 arg1 ...] – acquires args and sets up trap to run cmd:
    f () {
        declare -ag CMD_ARGV=("$@");  # array to give args to cmd
        kill -SIGUSR1 $$;             # this causes cmd to be run
        trap SIGUSR1;                 # unset the trap for SIGUSR1
        unset CMD_ARGV;               # clean up env...
        unset f;                      # incl. this function!
    };
    f'  # Finally, exec f, which will receive the args following "ac2".

E.g.:

> . alias-arg.sh
> ac2 one two
cmd(two one)
>
> # Check to see that command run via trap affects this environment:
> asv CMD_DONE
CMD_DONE=true

A nice thing about this solution is that all the special tricks used to handle positional parameters (arguments) to commands will work when composing the trapped command. The only difference is that array syntax must be used.

E.g.,

If you want "$@", use "${CMD_ARGV[@]}".

If you want "$#", use "${#CMD_ARGV[@]}".

Etc.

Padding
Padding is inside of a View.For example if you give android:paddingLeft=20dp, then the items inside the view will arrange with 20dp width from left.You can also use paddingRight, paddingBottom, paddingTop which are to give padding from right, bottom and top respectively.

Margin
Margin is outside of a View. For example if you give android:marginLeft=20dp , then the view will be arranged after 20dp from left.

You just need to make the siprimo and volteado methods static.

private static bool siprimo(long a)

and

private static long volteado(long a)

You need to access the matches in order to get at the SDI number. Here is a function that will do it (assuming there is only 1 SDI number per cell).

For the regex, I used "sdi followed by a space and one or more numbers". You had "sdi followed by a space and zero or more numbers". You can simply change the + to * in my pattern to go back to what you had.

Function ExtractSDI(ByVal text As String) As String

Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = "(sdi \d+)"
RE.Global = True
RE.IgnoreCase = True
Set allMatches = RE.Execute(text)

If allMatches.count <> 0 Then
    result = allMatches.Item(0).submatches.Item(0)
End If

ExtractSDI = result

End Function

If a cell may have more than one SDI number you want to extract, here is my RegexExtract function. You can pass in a third paramter to seperate each match (like comma-seperate them), and you manually enter the pattern in the actual function call:

Ex) =RegexExtract(A1, "(sdi \d+)", ", ")

Here is:

Function RegexExtract(ByVal text As String, _
                      ByVal extract_what As String, _
                      Optional seperator As String = "") As String

Dim i As Long, j As Long
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = extract_what
RE.Global = True
Set allMatches = RE.Execute(text)

For i = 0 To allMatches.count - 1
    For j = 0 To allMatches.Item(i).submatches.count - 1
        result = result & seperator & allMatches.Item(i).submatches.Item(j)
    Next
Next

If Len(result) <> 0 Then
    result = Right(result, Len(result) - Len(seperator))
End If

RegexExtract = result

End Function

*Please note that I have taken "RE.IgnoreCase = True" out of my RegexExtract, but you could add it back in, or even add it as an optional 4th parameter if you like.

I faced the same problem, for me the issue is different. It came because some of the maven dependencies are not downloaded.

a. I went through properties -> Java Buildpath -> Maven Dependencies and identified the missed libraries. 
b. Removed the missed libraries artifacts from pom.xml
c. Downloaded the libraries and added them explicitly.

Just use.

<![CDATA[ your text here ]]>

This will allow any characters except the ending

]]>

So you can include characters that would be illegal such as & and >. For example.

<element><![CDATA[ characters such as & and > are allowed ]]></element>

However, attributes will need to be escaped as CDATA blocks can not be used for them.

I was having this problem but i found out that it was a permissions problem I changed my permissions to 0744 and now it works. I don't know if this was your problem but it worked for me.

super late entry but GAAP is a good rule of thumb..

If your application needs to handle money values up to a trillion then this should work: 13,2 If you need to comply with GAAP (Generally Accepted Accounting Principles) then use: 13,4

Usually you should sum your money values at 13,4 before rounding of the output to 13,2.

I suggest loganfsmyths method, using an array to hold the data.

var bufs = [];
stdout.on('data', function(d){ bufs.push(d); });
stdout.on('end', function(){
  var buf = Buffer.concat(bufs);
}

IN my current working example, i am working with GRIDfs and npm's Jimp.

   var bucket = new GridFSBucket(getDBReference(), { bucketName: 'images' } );
    var dwnldStream = bucket.openDownloadStream(info[0]._id);// original size
  dwnldStream.on('data', function(chunk) {
       data.push(chunk);
    });
  dwnldStream.on('end', function() {
    var buff =Buffer.concat(data);
    console.log("buffer: ", buff);
       jimp.read(buff)
.then(image => {
         console.log("read the image!");
         IMAGE_SIZES.forEach( (size)=>{
         resize(image,size);
         });
});

I did some other research

with a string method but that did not work, per haps because i was reading from an image file, but the array method did work.

const DISCLAIMER = "DONT DO THIS";
var data = "";
stdout.on('data', function(d){ 
           bufs+=d; 
         });
stdout.on('end', function(){
          var buf = Buffer.from(bufs);
          //// do work with the buffer here

          });

When i did the string method i got this error from npm jimp

buffer:  <Buffer 00 00 00 00 00>
{ Error: Could not find MIME for Buffer <null>

basically i think the type coersion from binary to string didnt work so well.

In Python 3.2 a new html module was introduced, which is used for escaping reserved characters from HTML markup.

It has one function escape():

>>> import html
>>> html.escape('x > 2 && x < 7 single quote: \' double quote: "')
'x &gt; 2 &amp;&amp; x &lt; 7 single quote: &#x27; double quote: &quot;'

Here's a cleaned-up, non-eval-using version of Ram-swaroop's "works in all browsers" variety--works in all browsers!

function onReady(yourMethod) {
  var readyStateCheckInterval = setInterval(function() {
    if (document && document.readyState === 'complete') { // Or 'interactive'
      clearInterval(readyStateCheckInterval);
      yourMethod();
    }
  }, 10);
}
// use like
onReady(function() { alert('hello'); } );

It does wait an extra 10 ms to run, however, so here's a more complicated way that shouldn't:

function onReady(yourMethod) {
  if (document.readyState === 'complete') { // Or also compare to 'interactive'
    setTimeout(yourMethod, 1); // Schedule to run immediately
  }
  else {
    readyStateCheckInterval = setInterval(function() {
      if (document.readyState === 'complete') { // Or also compare to 'interactive'
        clearInterval(readyStateCheckInterval);
        yourMethod();
      }
    }, 10);
  }
}

// Use like
onReady(function() { alert('hello'); } );

// Or
onReady(functionName);

If you have multiple versions of a package / module, you need to be using virtualenv (emphasis mine):

virtualenv is a tool to create isolated Python environments.

The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform’s standard location is), it’s easy to end up in a situation where you unintentionally upgrade an application that shouldn’t be upgraded.

Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application.

Also, what if you can’t install packages into the global site-packages directory? For instance, on a shared host.

In all these cases, virtualenv can help you. It creates an environment that has its own installation directories, that doesn’t share libraries with other virtualenv environments (and optionally doesn’t access the globally installed libraries either).

That's why people consider insert(0, to be wrong -- it's an incomplete, stopgap solution to the problem of managing multiple environments.

Just add following code in <Head> Tag in your HTML Code. It will Form submission on Enter Key For all fields on form.

<script type="text/javascript">
    function stopEnterKey(evt) {
        var evt = (evt) ? evt : ((event) ? event : null);
        var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
        if ((evt.keyCode == 13) && (node.type == "text")) { return false; }
    }
    document.onkeypress = stopEnterKey;
</script>

How about:

public static T Min<T>(params T[] values)
{
    if (values == null) throw new ArgumentNullException("values");
    var comparer = Comparer<T>.Default;
    switch(values.Length) {
        case 0: throw new ArgumentException();
        case 1: return values[0];
        case 2: return comparer.Compare(values[0],values[1]) < 0
               ? values[0] : values[1];
        default:
            T best = values[0];
            for (int i = 1; i < values.Length; i++)
            {
                if (comparer.Compare(values[i], best) < 0)
                {
                    best = values[i];
                }
            }
            return best;
    }        
}
// overload for the common "2" case...
public static T Min<T>(T x, T y)
{
    return Comparer<T>.Default.Compare(x, y) < 0 ? x : y;
}

Works with any type that supports IComparable<T> or IComparable.

Actually, with LINQ, another alternative is:

var min = new[] {x,y,z}.Min();

I could not understand those 3 rules in the specs too well -- hope to have something that is more plain English -- but here is what I gathered from JavaScript: The Definitive Guide, 6th Edition, David Flanagan, O'Reilly, 2011:

Quote:

JavaScript does not treat every line break as a semicolon: it usually treats line breaks as semicolons only if it can’t parse the code without the semicolons.

Another quote: for the code

var a
a
=
3 console.log(a)

JavaScript does not treat the second line break as a semicolon because it can continue parsing the longer statement a = 3;

and:

two exceptions to the general rule that JavaScript interprets line breaks as semicolons when it cannot parse the second line as a continuation of the statement on the first line. The first exception involves the return, break, and continue statements

... If a line break appears after any of these words ... JavaScript will always interpret that line break as a semicolon.

... The second exception involves the ++ and -- operators ... If you want to use either of these operators as postfix operators, they must appear on the same line as the expression they apply to. Otherwise, the line break will be treated as a semicolon, and the ++ or -- will be parsed as a prefix operator applied to the code that follows. Consider this code, for example:

x 
++ 
y

It is parsed as x; ++y;, not as x++; y

So I think to simplify it, that means:

In general, JavaScript will treat it as continuation of code as long as it makes sense -- except 2 cases: (1) after some keywords like return, break, continue, and (2) if it sees ++ or -- on a new line, then it will add the ; at the end of the previous line.

The part about "treat it as continuation of code as long as it makes sense" makes it feel like regular expression's greedy matching.

With the above said, that means for return with a line break, the JavaScript interpreter will insert a ;

(quoted again: If a line break appears after any of these words [such as return] ... JavaScript will always interpret that line break as a semicolon)

and due to this reason, the classic example of

return
{ 
  foo: 1
}

will not work as expected, because the JavaScript interpreter will treat it as:

return;   // returning nothing
{
  foo: 1
}

There has to be no line-break immediately after the return:

return { 
  foo: 1
}

for it to work properly. And you may insert a ; yourself if you were to follow the rule of using a ; after any statement:

return { 
  foo: 1
};

simple in python 3.6

o = open('outfile','w')

print('hello world', file=o)

o.close()

I was looking for something like I did in Perl

my $printname = "outfile"

open($ph, '>', $printname)
    or die "Could not open file '$printname' $!";

print $ph "hello world\n";

String logStringVal= date+"";

Can convert the long into string object, cool shortcut for converting into string...but use of String.valueOf(date); is advisable

For ExpressJs router:

router.post('/login', async(req, res) => {
    return res.send({redirect: '/yoururl'});
})

Client-side:

    success: function (response) {
        if (response.redirect) {
            window.location = response.redirect
        }
    },

This error means that remote repository has had other commits and has paced ahead of your local branch.
I try doing a git pull followed by a git push. If their are No conflicting changes, git pull gets the latest code to my local branch while keeping my changes intact.
Then a git push pushes my changes to the master branch.

If the multiple csv files are zipped, you may use zipfile to read all and concatenate as below:

import zipfile
import pandas as pd

ziptrain = zipfile.ZipFile('yourpath/yourfile.zip')

train = []

train = [ pd.read_csv(ziptrain.open(f)) for f in ziptrain.namelist() ]

df = pd.concat(train)

    

relate to this suggestion : https://stackoverflow.com/a/20215481/3080835

also i had to add this to Application element in the Manifest:

<meta-data 
           android:name="com.google.android.gms.version" 
           android:value="@integer/google_play_services_version" />

and it worked perfectly.

Just like any other click event, you can use jQuery to register an element, set an id to the element and listen to events like so:

$('#myButton').on('click', function(event) {
  event.preventDefault(); // To prevent following the link (optional)
  ...
});

You can also use inline javascript in the onclick attribute:

<a ... onclick="myFunc();">..</a>

Here's a Boolean thing:

if (not suffix == "flac" )  or (not suffix == "cue" ):   # WRONG! FAILS
    print  filename + ' is not a flac or cue file'

but

if not (suffix == "flac"  or suffix == "cue" ):     # CORRECT!
       print  filename + ' is not a flac or cue file'

(not a) or (not b) == not ( a and b ) , is false only if a and b are both true

not (a or b) is true only if a and be are both false.

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

Whenever you will try to run a project with build tool version not present in studio, You will face this error.

As of now in 2017, It has been made really simple by Android Studio.

It will prompt you about this issue, along with something like this

You just have to click on it and the system will download to the build version required to run the project.

Many ways to skin the cat here and @Mitch's suggestion is a good way. If you want the client form to have more 'control', you may want to pass the instance of the parent to the child when created and then you can call any public parent method on the child.

The Array and List<T> classes already have ForEach methods, though only this specific implementation. (Note that the former is static, by the way).

Not sure it really offers a great advantage over a foreach statement, but you could write an extension method to do the job for all IEnumerable<T> objects.

public static void ForEach<T>(this IEnumerable<T> source, Action<T> action)
{
    foreach (var item in source)
        action(item);
}

This would allow the exact code you posted in your question to work just as you want.

I think a better approach than setting the platform's default character set, especially as you seem to have restrictions on affecting the application deployment, let alone the platform, is to call the much safer String.getBytes("charsetName"). That way your application is not dependent on things beyond its control.

I personally feel that String.getBytes() should be deprecated, as it has caused serious problems in a number of cases I have seen, where the developer did not account for the default charset possibly changing.

This is a good article about the subject.

To summarize,

1. Managed code is not compiled to machine code but to an intermediate language which is interpreted and executed by some service on a machine and is therefore operating within a (hopefully!) secure framework which handles dangerous things like memory and threads for you. In modern usage this frequently means .NET but does not have to.

An application program that is executed within a runtime engine installed in the same machine. The application cannot run without it. The runtime environment provides the general library of software routines that the program uses and typically performs memory management. It may also provide just-in-time (JIT) conversion from source code to executable code or from an intermediate language to executable code. Java, Visual Basic and .NET's Common Language Runtime (CLR) are examples of runtime engines. (Read more)

2. Unmanaged code is compiled to machine code and therefore executed by the OS directly. It therefore has the ability to do damaging/powerful things Managed code does not. This is how everything used to work, so typically it's associated with old stuff like .dlls.

An executable program that runs by itself. Launched from the operating system, the program calls upon and uses the software routines in the operating system, but does not require another software system to be used. Assembly language programs that have been assembled into machine language and C/C++ programs compiled into machine language for a particular platform are examples of unmanaged code.(Read more)

3. Native code is often synonymous with Unmanaged, but is not identical.

According to Amazon:

Write, read, and delete objects containing from 0 bytes to 5 terabytes of data each. The number of objects you can store is unlimited.

Source: http://aws.amazon.com/s3/details/ as of Sep 3, 2015.

As myJSON is an object you can just set its properties, for example:

myJSON.list1 = ["1","2"];

If you dont know the name of the properties, you have to use the array access syntax:

myJSON['list'+listnum] = ["1","2"];

If you want to add an element to one of the properties, you can do;

myJSON.list1.push("3");

Above answer can be considered to be confusing a little. String methods are not modifying original object. They return new object. It must be:

var str = "Sonic Free Games";
str = str.replace(/\s+/g, '-').toLowerCase(); //new object assigned to var str

You can also use this method:

<input type="text" class="@(@mvccondition ? "true-class" : "false-class")">

Try this .. Good luck Thanks.

Auxiliary answer

Manoj Govindan's answer is correct but I saw that comment:

I know that this thread is quite old, however, I am missing here one option. If you have metadata (in any format) that you want to send along with the data to upload, you can make a single multipart/related request.

The Multipart/Related media type is intended for compound objects consisting of several inter-related body parts.

You can check RFC 2387 specification for more in-depth details.

Basically each part of such a request can have content with different type and all parts are somehow related (e.g. an image and it metadata). The parts are identified by a boundary string, and the final boundary string is followed by two hyphens.

Example:

POST /upload HTTP/1.1
Host: www.hostname.com
Content-Type: multipart/related; boundary=xyz
Content-Length: [actual-content-length]

--xyz
Content-Type: application/json; charset=UTF-8

{
    "name": "Sample image",
    "desc": "...",
    ...
}

--xyz
Content-Type: image/jpeg

[image data]
[image data]
[image data]
...
--foo_bar_baz--

BadImageFormatException, in my experience, is almost always to do with x86 versus x64 compiled assemblies. It sounds like your C++ assembly is compiled for x86 and you are running on an x64 process. Is that correct?

Instead of using AnyCPU/Mixed as the platform. Try to manually set it to x86 and see if it will run after that.

Hope this helps.

USING plt.rcParams

There is also this workaround in case you want to change the size without using the figure environment. So in case you are using plt.plot() for example, you can set a tuple with width and height.

import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = (20,3)

This is very useful when you plot inline (e.g. with IPython Notebook). As @asamaier noticed is preferable to not put this statement in the same cell of the imports statements.

Conversion to cm

The figsize tuple accepts inches so if you want to set it in centimetres you have to divide them by 2.54 have a look to this question.

var escapedData = escape("hel'lo");   
output = "%27hel%27lo%27" which can be used in the attribute.

again to read the value from the attr

var unescapedData = unescape("%27hel%27lo%27")
output = "'hel'lo'"

This will be helpful if you have huge json stringify data to be used in the attribute

to create directory

ansible host_name -m file -a "dest=/home/ansible/vndir state=directory"

You can also use "[.]"

grep -r "0[.]49"

var SendInfo= { SendInfo: [... your elements ...]};

        $.ajax({
            type: 'post',
            url: 'Your-URI',
            data: JSON.stringify(SendInfo),
            contentType: "application/json; charset=utf-8",
            traditional: true,
            success: function (data) {
                ...
            }
        });

and in action

public ActionResult AddDomain(IEnumerable<PersonSheets> SendInfo){
...

you can bind your array like this

var SendInfo = [];

$(this).parents('table').find('input:checked').each(function () {
    var domain = {
        name: $("#id-manuf-name").val(),
        address: $("#id-manuf-address").val(),
        phone: $("#id-manuf-phone").val(),
    }

    SendInfo.push(domain);
});

hope this can help you.

Based on luttken's answer. Thought I'd add my twist :)

function dateIsInBetween(\DateTime $from, \DateTime $to, \DateTime $subject)
{
    return $subject->getTimestamp() > $from->getTimestamp() && $subject->getTimestamp() < $to->getTimestamp() ? true : false;
}

$paymentDate       = new \DateTime('now');
$contractDateBegin = new \DateTime('01/01/2001');
$contractDateEnd   = new \DateTime('01/01/2016');

echo dateIsInBetween($contractDateBegin, $contractDateEnd, $paymentDate) ? "is between" : "NO GO!";

Blazemonger's reply (above or below) needs voting up - but I don't have enough points.

I wanted to add a grey bar across some 20px wide CSS round buttons to indicate "not available" and tweaked Blazemonger's css:

.round_btn:after {
    content:"";    /* required property */
    position: absolute;
    top: 6px;
    left: -1px;
    border-top: 6px solid rgba(170,170,170,0.65);
    height: 6px;
    width: 19px;
}

As you say, this can mean that your IP address has been blocked. I'd make sure that you specify the key parameter on the query string for the Geocoding API request.

https://maps.googleapis.com/maps/api/geocode/xml?sensor=false&address=Placename&key=XXxxxXXxXxxxxXXxx

Also make sure that if you've set up IP Address Restrictions within the Developer Console, you've allowed the correct IP address, just click the project within the list and you'll see the allowed IPs.

If you're still running into issues, you might want to look into printing out the values of the status and error_message elements from the response from Google, you'll see something like this:

REQUEST_DENIED - This IP, site or mobile application is not authorized to use this API key. Request received from IP address 123.4.5.678, with empty referer

If it doesn't mention an IP address restriction, it may well give you enough information about the problem to Google a fix.

If you are sure you want to remove all commit history, simply delete the .git directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:

git init
git remote add origin [email protected]:user/repo

now commit your current version of code

git add *
git commit -am 'message'

and finally force the update to GitHub:

git push -f origin master

However, I suggest backing up the history (the .git folder in the repository) before taking these steps!

would take time to route through TeamViewer's servers (TeamViewer bypasses corporate Symmetric NATs by simply proxying traffic through their servers)

You'll find that TeamViewer rarely needs to relay traffic through their own servers. TeamViewer penetrates NAT and networks complicated by NAT using NAT traversal (I think it is UDP hole-punching, like Google's libjingle).

They do use their own servers to middle-man in order to do the handshake and connection set-up, but most of the time the relationship between client and server will be P2P (best case, when the hand-shake is successful). If NAT traversal fails, then TeamViewer will indeed relay traffic through its own servers.

I've only ever seen it do this when a client has been behind double-NAT, though.

Use JSON.

In the following example $php_variable can be any PHP variable.

<script type="text/javascript">
    var obj = <?php echo json_encode($php_variable); ?>;
</script>

In your code, you could use like the following:

drawChart(600/50, <?php echo json_encode($day); ?>, ...)

In cases where you need to parse out an object from JSON-string (like in an AJAX request), the safe way is to use JSON.parse(..) like the below:

var s = "<JSON-String>";
var obj = JSON.parse(s);
