Just use parenthesis and 'count'. This applies to Powershell v3

(get-alias).count

Simply goto MySql Console.

If using Wamp:

1. Click on Wamp icon just beside o'clock.
2. In MySql section click on MySql Console.
3. Press enter (means no password) twice.
4. mysql commands preview like this : mysql>
5. SET PASSWORD FOR 'root'@'localhost' = PASSWORD('secret');

That's it. This set your root password to secret

In order to set user privilege to default one:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('');

Works like a charm!

Adding to what deceze said above. This is a parse error, so in order to debug a parse error, create a new file in the root named debugSyntax.php. Put this in it:

<?php

///////    SYNTAX ERROR CHECK    ////////////
error_reporting(E_ALL);
ini_set('display_errors','On');

//replace "pageToTest.php" with the file path that you want to test. 
include('pageToTest.php'); 

?>

Run the debugSyntax.php page and it will display parse errors from the page that you chose to test.

From my notes:

http://maps.google.com/maps?q=37.4185N+122.08774W+(label)&ll=37.419731,-122.088715&spn=0.004250,0.011579&t=h&iwloc=A&hl=en

Which parses like this:

    q=latN+lonW+(label)     location of teardrop

    t=k             keyhole (satelite map)
    t=h             hybrid

    ll=lat,-lon     center of map
    spn=w.w,h.h     span of map, degrees

iwloc has something to do with the info window. hl is obviously language.

Trivial answer yet accurate in some cases, such as the one that brought me here. I was working in a repo which was new for me and I added a file which was not seen as new by the status.

It ends up that the file matched a pattern in the .gitignore file.

The purpose of a view is to use the query over and over again. To that end, SQL Server, Oracle, etc. will typically provide a "cached" or "compiled" version of your view, thus improving its performance. In general, this should perform better than a "simple" query, though if the query is truly very simple, the benefits may be negligible.

Now, if you're doing a complex query, create the view.

When you use setcookie, you can either set the expiration time to 0 or simply omit the parametre - the cookie will then expire at the end of session (ie, when you close the browser).

the alphanum function (self answered) have a bug, but I don't know why. For text "cas synt ls 75W140 1L" return "cassyntls75W1401", "L" from the end is missing some how.

Now I use

delimiter //
DROP FUNCTION IF EXISTS alphanum //
CREATE FUNCTION alphanum(prm_strInput varchar(255))
RETURNS VARCHAR(255)
DETERMINISTIC
BEGIN
  DECLARE i INT DEFAULT 1;
  DECLARE v_char VARCHAR(1);
  DECLARE v_parseStr VARCHAR(255) DEFAULT ' ';
WHILE (i <= LENGTH(prm_strInput) )  DO
  SET v_char = SUBSTR(prm_strInput,i,1);
  IF v_char REGEXP  '^[A-Za-z0-9]+$' THEN 
        SET v_parseStr = CONCAT(v_parseStr,v_char);  
  END IF;
  SET i = i + 1;
END WHILE;
RETURN trim(v_parseStr);
END
//

Simply You can use following methods.

using (WebClient client = new WebClient()) 
{
    client.DownloadFile(new Uri(url), @"c:\temp\image35.png");
    // OR 
    client.DownloadFileAsync(new Uri(url), @"c:\temp\image35.png");
}

These methods are almost same as DownloadString(..) and DownloadStringAsync(...). They store the file in Directory rather than in C# string and no need of Format extension in URi

If You don't know the Format(.png, .jpeg etc) of Image

public void SaveImage(string filename, ImageFormat format)
{    
    WebClient client = new WebClient();
    Stream stream = client.OpenRead(imageUrl);
    Bitmap bitmap;  bitmap = new Bitmap(stream);

    if (bitmap != null)
    {
        bitmap.Save(filename, format);
    }

    stream.Flush();
    stream.Close();
    client.Dispose();
}

Using it

try
{
    SaveImage("--- Any Image Path ---", ImageFormat.Png)
}
catch(ExternalException)
{
    // Something is wrong with Format -- Maybe required Format is not 
    // applicable here
}
catch(ArgumentNullException)
{   
    // Something wrong with Stream
}

Try using the not() method instead of the :not() selector.

$(".content a").click(function() {
    $(".content a").not(this).hide("slow");
});

The expression df1$id %in% idNums1 produces a logical vector. To negate it, you need to negate the whole vector:

!(df1$id %in% idNums1)

Just want to add to Ben's answer on drop_duplicates:

keep : {‘first’, ‘last’, False}, default ‘first’

• first : Drop duplicates except for the first occurrence.

• last : Drop duplicates except for the last occurrence.

• False : Drop all duplicates.

So setting keep to False will give you desired answer.

DataFrame.drop_duplicates(*args, **kwargs) Return DataFrame with duplicate rows removed, optionally only considering certain columns

Parameters: subset : column label or sequence of labels, optional Only consider certain columns for identifying duplicates, by default use all of the columns keep : {‘first’, ‘last’, False}, default ‘first’ first : Drop duplicates except for the first occurrence. last : Drop duplicates except for the last occurrence. False : Drop all duplicates. take_last : deprecated inplace : boolean, default False Whether to drop duplicates in place or to return a copy cols : kwargs only argument of subset [deprecated] Returns: deduplicated : DataFrame

This syntax has changed with the newer Apache HTTPd server, please see upgrade to apache 2.4 doc for full details.

2.2 configuration syntax was

Order deny,allow
Deny from all

2.4 configuration now is

Require all denied

Thus, this 2.2 syntax

order deny,allow
deny from all
allow from 127.0.0.1

Would ne now written

Require local

DataGrip has the same functionality as pgAdmin. You can right click on a table and you will see option to auto-generate create table statement.

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.

Try unmounting the overflow partition:

umount /tmp

or

umount overflow

It's working for me:

<div class="links">
    <ul>
    <li class="social-share facebook">Share on Facebook</li>
    <li class="social-share twitter">Share on Twitter</li>
    <li class="social-share linkedin">Share on LinkedIn</li>
    </ul>
</div>

And in js file add this:

setShareLinks();

    function socialWindow(url) {
    var left = (screen.width -570) / 2;
    var top = (screen.height -570) / 2;
    var params = "menubar=no,toolbar=no,status=no,width=570,height=570,top=" + top + ",left=" + left;  window.open(url,"NewWindow",params);}

function setShareLinks() {
    var pageUrl = encodeURIComponent(document.URL);
    var tweet = encodeURIComponent($("meta[property='og:description']").attr("content"));

$(".social-share.facebook").on("click", function() { url="https://www.facebook.com/sharer.php?u=" + pageUrl;
socialWindow(url);
});

$(".social-share.twitter").on("click", function() {
url = "https://twitter.com/intent/tweet?url=" + pageUrl + "&text=" + tweet;
socialWindow(url);
});

$(".social-share.linkedin").on("click", function() {
    url = "https://www.linkedin.com/shareArticle?mini=true&url=" + pageUrl;
socialWindow(url);
})
}

Hope this will work well.

I personally prefer using this shortcut. The output will still be the same, but you don't need to store the month and year in separate variables

$dateValue = '2012-01-05';
$formattedValue = date("F Y", strtotime($dateValue));
echo $formattedValue; //Output should be January 2012

A little side note on using this trick, you can use comma's to separate the month and year like so:

$formattedValue = date("F, Y", strtotime($dateValue));
echo $formattedValue //Output should be January, 2012

When you say "called" I'm going to assume you mean an ID tag.

To make it cross-brower, I wouldn't suggest using the CSS3 [], although it is an option. This being said, give each of your textboxes a class like "tb" and the radio button "rb".

Then:

#divContainer .tb { width: 150px }
#divContainer .rb { width: 20px }

This assumes you are using the same classes elsewhere, if not, this will suffice:

.tb { width: 150px }
.rb { width: 20px }

As @David mentioned, to access anything within the division itself:

#divContainer [element] { ... }

Where [element] is whatever HTML element you need.

A Unix tick is 1 second (if I remember well), and a .NET tick is 100 nanoseconds.

If you've been encountering problems with nanoseconds, you might want to try using AddTick(10000000 * value).

there is a alternative to margin-left:auto; margin-right: auto; or margin:0 auto; for the ones that use position:absolute; this is how:
you set the left position of the element to 50% (left:50%;) but that will not center it correctly in order for the element to be centered correctly you need to give it a margin of minus half of it`s width, that will center your element perfectly

here is an example: http://jsfiddle.net/35ERq/3/

I use a hash and a salt for my password encryption (it's the same hash that Asp.Net Membership uses):

private string PasswordSalt
{
   get
   {
      var rng = new RNGCryptoServiceProvider();
      var buff = new byte[32];
      rng.GetBytes(buff);
      return Convert.ToBase64String(buff);
   }
}

private string EncodePassword(string password, string salt)
{
   byte[] bytes = Encoding.Unicode.GetBytes(password);
   byte[] src = Encoding.Unicode.GetBytes(salt);
   byte[] dst = new byte[src.Length + bytes.Length];
   Buffer.BlockCopy(src, 0, dst, 0, src.Length);
   Buffer.BlockCopy(bytes, 0, dst, src.Length, bytes.Length);
   HashAlgorithm algorithm = HashAlgorithm.Create("SHA1");
   byte[] inarray = algorithm.ComputeHash(dst);
   return Convert.ToBase64String(inarray);
}

Nowadays, it's better to use queues than threads (for those who don't use Laravel there are tons of other implementations out there like this).

The basic idea is, your original PHP script puts tasks or jobs into a queue. Then you have queue job workers running elsewhere, taking jobs out of the queue and starts processing them independently of the original PHP.

The advantages are:

1. Scalability - you can just add worker nodes to keep up with demand. In this way, tasks are run in parallel.
2. Reliability - modern queue managers such as RabbitMQ, ZeroMQ, Redis, etc, are made to be extremely reliable.

When you mark your method as @Transactional, occurrence of any exception inside your method will mark the surrounding TX as roll-back only (even if you catch them). You can use other attributes of @Transactional annotation to prevent it of rolling back like:

@Transactional(rollbackFor=MyException.class, noRollbackFor=MyException2.class)

There is no way to get the old password back. Log into the SQL server management console as a machine or domain admin using integrated authentication, you can then change any password (including sa).

Start the SQL service again and use the new created login (recovery in my example) Go via the security panel to the properties and change the password of the SA account.

Now write down the new SA password.

Run it on a single command line like so:

powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile 
  -WindowStyle Hidden -Command "Get-AppLockerFileInformation -Directory <folderpath> 
  -Recurse -FileType <type>"

You may set the timeout either globally for entire server:

var server = app.listen();
server.setTimeout(500000);

or just for specific route:

app.post('/xxx', function (req, res) {
   req.setTimeout(500000);
});

If it's just for viewing data, I use simple foreach or even aspRepeater. For editing I build specialized views and actions. Didn't like webforms GridView inline edit capabilities anyway, this is kinda much clearer and better - one view for viewing and another for edit/new.

If you have control to the {this.props.match.description} and if you are using JSX. I would recommend not to use "dangerouslySetInnerHTML".

// In JSX, you can define a html object rather than a string to contain raw HTML
let description = <h1>Hi there!</h1>;

// Here is how you print
return (
    {description}
);

Here is my sugestion:

Dim i As integer, j as integer

With Worksheets("TimeOut")
    i = 26
    Do Until .Cells(8, i).Value = ""
        For j = 9 to 100 ' I do not know how many rows you will need it.'
            .Cells(j, i).Formula = "YourVolFormulaHere"
            .Cells(j, i + 1).Formula = "YourCapFormulaHere"
        Next j

        i = i + 2
    Loop
 End With

So I worked out at the end that you cannot uninstall 3.4 as it is default on Ubuntu.

All I did was simply remove Jupyter and then alias python=python2.7 and install all packages on Python 2.7 again.

Arguably, I can install virtualenv but me and my colleagues are only using 2.7. I am just going to be lazy in this case :)

Here are two approaches. The one is similar to your approach

#include <iostream>
#include <string>
#include <limits>
#include <algorithm>

int main()
{
    while ( true )
    {
        std::cout << "Enter a non-negative number (0-exit): ";

        unsigned long long x = 0;
        std::cin >> x;

        if ( !x ) break;

        const unsigned long long base = 2;

        std::string s;
        s.reserve( std::numeric_limits<unsigned long long>::digits ); 

        do { s.push_back( x % base + '0' ); } while ( x /= base );

        std::cout << std::string( s.rbegin(), s.rend() )  << std::endl;
    }
}

and the other uses std::bitset as others suggested.

#include <iostream>
#include <string>
#include <bitset>
#include <limits>

int main()
{
    while ( true )
    {
        std::cout << "Enter a non-negative number (0-exit): ";

        unsigned long long x = 0;
        std::cin >> x;

        if ( !x ) break;

        std::string s = 
            std::bitset<std::numeric_limits<unsigned long long>::digits>( x ).to_string();

        std::string::size_type n = s.find( '1' ); 
        std::cout << s.substr( n )  << std::endl;
    }
}

As also noted in the docs here.
Go to Python X.X/Lib and add these lines to the site.py there,

import sys
sys.path.append("yourpathstring")

This changes your sys.path so that on every load, it will have that value in it..

As stated here about site.py,

This module is automatically imported during initialization. Importing this module will append site-specific paths to the module search path and add a few builtins.

For other possible methods of adding some path to sys.path see these docs

I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.

Set cn = CreateObject("ADODB.Connection")
With cn
 .Provider = "Microsoft.Jet.OLEDB.4.0"
  .ConnectionString = "Data Source=D:\test.xls " & _
  ";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
  For i = 0 To rs.Fields.Count - 1
    Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
    strNaam = rs.Fields(0).Value
  Next
  rs.MoveNext
Loop
rs.Close

There are other ways, depending on what you want to do, such as GetString (GetString Method Description).

If you want to merge changes in SubBranch to MainBranch

1. you should be on MainBranch git checkout MainBranch
2. then run merge command git merge SubBranch

I don't think it's "bad" idea to find out who is the view controller for some cases. What could be a bad idea is to save the reference to this controller as it could change just as superviews change. In my case I have a getter that traverses the responder chain.

//.h

@property (nonatomic, readonly) UIViewController * viewController;

//.m

- (UIViewController *)viewController
{
    for (UIResponder * nextResponder = self.nextResponder;
         nextResponder;
         nextResponder = nextResponder.nextResponder)
    {
        if ([nextResponder isKindOfClass:[UIViewController class]])
            return (UIViewController *)nextResponder;
    }

    // Not found
    NSLog(@"%@ doesn't seem to have a viewController". self);
    return nil;
}

Try this..

select starttime,endtime, case
  when DATEDIFF(minute,starttime,endtime) < 60  then DATEDIFF(minute,starttime,endtime) 
  when DATEDIFF(minute,starttime,endtime) >= 60
  then '60,'+ cast( (cast(DATEDIFF(minute,starttime,endtime) as int )-60) as nvarchar(50) )
end from TestTable123416

All You need is DateDiff..

A good method which is a favorite of mine and for many I'm sure, is to make use of foreach which will output each color you chose, and appear on screen one underneath each other.

When it comes to using checkboxes, you kind of do not have a choice but to use foreach, and that's why you only get one value returned from your array.

Here is an example using $_GET. You can however use $_POST and would need to make both directives match in both files in order to work properly.

###HTML FORM

<form action="third.php" method="get">
    Red<input type="checkbox" name="color[]" value="red">
    Green<input type="checkbox" name="color[]" value="green">
    Blue<input type="checkbox" name="color[]" value="blue">
    Cyan<input type="checkbox" name="color[]" value="cyan">
    Magenta<input type="checkbox" name="color[]" value="Magenta">
    Yellow<input type="checkbox" name="color[]" value="yellow">
    Black<input type="checkbox" name="color[]" value="black">
    <input type="submit" value="submit">
</form>

###PHP (using $_GET) using third.php as your handler

<?php

$name = $_GET['color'];

// optional
// echo "You chose the following color(s): <br>";

foreach ($name as $color){ 
    echo $color."<br />";
}

?>

Assuming having chosen red, green, blue and cyan as colors, will appear like this:

red
green
blue
cyan

##OPTION #2

You can also check if a color was chosen. If none are chosen, then a seperate message will appear.

<?php

$name = $_GET['color'];

if (isset($_GET['color'])) {
    echo "You chose the following color(s): <br>";

    foreach ($name as $color){
        echo $color."<br />";
    }
} else {
    echo "You did not choose a color.";
}

?>

##Additional options: To appear as a list: (<ul></ul> can be replaced by <ol></ol>)

<?php

$name = $_GET['color'];

if (isset($_GET['color'])) {
    echo "You chose the following color(s): <br>";
    echo "<ul>";
    foreach ($name as $color){
        echo "<li>" .$color."</li>";
    }
    echo "</ul>";
} else {
    echo "You did not choose a color.";
}

?>

Tools --> Options --> Designers node --> Uncheck " Prevent saving changes that require table recreation ".

You can use varargs

public function yourFunction(Parameter... parameters)

The easiest solution is to convert your categorical variable to a factor prior to the subsetting. Bottomline is that you need a factor variable with exact the same levels in all your subsets.

library(ggplot2)
dataset <- data.frame(category = rep(LETTERS[1:5], 100), 
    x = rnorm(500, mean = rep(1:5, 100)), y = rnorm(500, mean = rep(1:5, 100)))
dataset$fCategory <- factor(dataset$category)
subdata <- subset(dataset, category %in% c("A", "D", "E"))

With a character variable

ggplot(dataset, aes(x = x, y = y, colour = category)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = category)) + geom_point()

With a factor variable

ggplot(dataset, aes(x = x, y = y, colour = fCategory)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = fCategory)) + geom_point()

First install pylint-django using following command

$ pip install pylint-django

Then run the second command as follows:

$ pylint test_file.py --load-plugins pylint_django

--load-plugins pylint_django is necessary for correctly review a code of django

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

Well if you are doing this in Asp.Net or have access to HttpContext.Current.Request I'd say these are easier and more general ways of getting them:

var scheme = Request.Url.Scheme; // will get http, https, etc.
var host = Request.Url.Host; // will get www.mywebsite.com
var port = Request.Url.Port; // will get the port
var path = Request.Url.AbsolutePath; // should get the /pages/page1.aspx part, can't remember if it only get pages/page1.aspx

I hope this helps. :)

<project name="Build" basedir="." default="clean">

       <echo>Value Buld is now  ${build.type} is set</echo>
    </target>
</project>

In my Case DPARAM_BUILD_TYPE=Debug if it is supplied than, I need to build for for Debug otherwise i need to go for building Release build. I write like above condition it worked and i have tested as below it is working fine for me.

And property ${build.type} we can pass this to other target or macrodef for processing which i am doing in my other ant macrodef.

D:\>ant -DPARAM_BUILD_TYPE=Debug
Buildfile: D:\build.xml
clean:
     [echo] Value Buld is now  Debug is set
     [echo] Value Buld is now  Debug is set
     [echo] Value Buld is now  Debug is set
main:
BUILD SUCCESSFUL
Total time: 0 seconds
D:\>ant
Buildfile: D:\build.xml
clean:
     [echo] Value Buld is now  ${PARAM_BUILD_TYPE} is set
     [echo] Value Buld is now  ${PARAM_BUILD_TYPE} is set
     [echo] Value Buld is now  Release is set
main:
BUILD SUCCESSFUL
Total time: 0 seconds

It work for me to implement condition so posted hope it will helpful.

The accepted answer of this post will cause error in the case when the string length is lest than 5. So i have a better solution. We can use this simple code :

If(str.Length <= 5, str, str.Substring(str.Length - 5))

You can test it with variable length string.

    Dim str, result As String
    str = "11!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)
    str = "I will be going to school in 2011!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)

Another simple but efficient solution i found :

str.Substring(str.Length - Math.Min(5, str.Length))

just use this attribute

[System.Web.Http.HttpGet]

not need this line of code:

[System.Web.Http.AcceptVerbs("GET", "POST")]

android:background="@android:color/transparent"

The above is something that I know... I think creating a custom button class is the best idea

API Level 11
Recently I came across this android:alpha xml attribute which takes a value between 0 and 1. The corresponding method is setAlpha(float).

This might be a stupid solution. But it works. If you can improve it, please let me know.

OnCreate of your Service: I have used WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH flag. This is the only change in service.

@Override
    public void onCreate() {
        super.onCreate();
        Toast.makeText(getBaseContext(),"onCreate", Toast.LENGTH_LONG).show();
        mView = new HUDView(this);
        WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
                PixelFormat.TRANSLUCENT);
        params.gravity = Gravity.RIGHT | Gravity.TOP;
        params.setTitle("Load Average");
        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        wm.addView(mView, params);
    }

Now, you will start getting each and every click event. So, you need to rectify in your event handler.

In your ViewGroup touch event

@Override
public boolean onTouchEvent(MotionEvent event) {

    // ATTENTION: GET THE X,Y OF EVENT FROM THE PARAMETER
    // THEN CHECK IF THAT IS INSIDE YOUR DESIRED AREA


    Toast.makeText(getContext(),"onTouchEvent", Toast.LENGTH_LONG).show();
    return true;
}

Also you may need to add this permission to your manifest:

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

To avoid memory leaks you may use smart pointers whenever you can. There are basically 2 different types of smart pointers in C++

• Reference counted (e.g. boost::shared_ptr / std::tr1:shared_ptr)
• non reference counted (e.g. boost::scoped_ptr / std::auto_ptr)

The main difference is that reference counted smart pointers can be copied (and used in std:: containers) while scoped_ptr cannot. Non reference counted pointers have almost no overhead or no overhead at all. Reference counting always introduces some kind of overhead.

(I suggest to avoid auto_ptr, it has some serious flaws if used incorrectly)

Also note that redirect: and forward: prefixes are handled by UrlBasedViewResolver, so you need to have at least one subclass of UrlBasedViewResolver among your view resolvers, such as InternalResourceViewResolver.

Since sudo will not work with redirection >, I like the tee command for this purpose

echo "" | sudo tee fileName

I came from PHP, where you can increment char (A to B, Z to AA, AA to AB etc.) using ++ operator. I made a simple function which does the same in Python. You can also change list of chars to whatever (lowercase, uppercase, etc.) is your need.

# Increment char (a -> b, az -> ba)
def inc_char(text, chlist = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'):
    # Unique and sort
    chlist = ''.join(sorted(set(str(chlist))))
    chlen = len(chlist)
    if not chlen:
        return ''
    text = str(text)
    # Replace all chars but chlist
    text = re.sub('[^' + chlist + ']', '', text)
    if not len(text):
        return chlist[0]
    # Increment
    inc = ''
    over = False
    for i in range(1, len(text)+1):
        lchar = text[-i]
        pos = chlist.find(lchar) + 1
        if pos < chlen:
            inc = chlist[pos] + inc
            over = False
            break
        else:
            inc = chlist[0] + inc
            over = True
    if over:
        inc += chlist[0]
    result = text[0:-len(inc)] + inc
    return result

Clarification Here:

While this will work:

 JsonNode rootNode = objectMapper.readTree(file);
 Iterator<Map.Entry<String, JsonNode>> fields = rootNode.fields();
 while (fields.hasNext()) {
    Map.Entry<String, JsonNode> entry = fields.next();
    log.info(entry.getKey() + ":" + entry.getValue())
 }

This will not:

JsonNode rootNode = objectMapper.readTree(file);

while (rootNode.fields().hasNext()) {
    Map.Entry<String, JsonNode> entry = rootNode.fields().next();
    log.info(entry.getKey() + ":" + entry.getValue())
}

So be careful to declare the Iterator as a variable and use that.

Be sure to use the fasterxml library rather than codehaus.

A very simple method would be to use the extract method to select all the digits. Simply supply it the regular expression '\d+' which extracts any number of digits.

df['result'] = df.result.str.extract(r'(\d+)', expand=True).astype(int)
df

    time  result
1  09:00      52
2  10:00      62
3  11:00      44
4  12:00      30
5  13:00     110

var currentPageUrlIs = "";
if (typeof this.href != "undefined") {
       currentPageUrlIs = this.href.toString().toLowerCase(); 
}else{ 
       currentPageUrlIs = document.location.toString().toLowerCase();
}

The above code can also help someone

You need to do two things, one is to set the height to 100% which you already did. Second is set the position to absolute. That should do the trick.

html,
body {
  height: 100%;
  min-height: 100%;
  position: absolute;
}

In Python, a list is a dynamic array. You can create one like this:

lst = [] # Declares an empty list named lst

Or you can fill it with items:

lst = [1,2,3]

You can add items using "append":

lst.append('a')

You can iterate over elements of the list using the for loop:

for item in lst:
    # Do something with item

Or, if you'd like to keep track of the current index:

for idx, item in enumerate(lst):
    # idx is the current idx, while item is lst[idx]

To remove elements, you can use the del command or the remove function as in:

del lst[0] # Deletes the first item
lst.remove(x) # Removes the first occurence of x in the list

Note, though, that one cannot iterate over the list and modify it at the same time; to do that, you should instead iterate over a slice of the list (which is basically a copy of the list). As in:

 for item in lst[:]: # Notice the [:] which makes a slice
       # Now we can modify lst, since we are iterating over a copy of it

Sounds like you're working in just one table so something like this:

update your_table
set B = A
where B is null

You need to specify an access modifier for your variable. In this case you want it public.

public class Variables
{
    public static string name = "";
}

After this you can use the variable like this.

Variables.name

Try =index(ARRAY, ROW, COLUMN)

where: Array: select the whole sheet Row, Column: Your row and column references

That should be easier to understand to those looking at the formula.

Also, if issue appears while executing ./gradlew command, setting java home in gradle.properties file, solves this issue:

org.gradle.java.home=/usr/java/jdk1.8.0_45/

If you want to keep the same tree as one of the branch you want to merge (ie. not a real "merge"), you can do it like this.

# Check if you can fast-forward
if git merge-base --is-ancestor a b; then
    git update-ref refs/heads/a refs/heads/b
    exit
fi

# Else, create a "merge" commit
commit="$(git commit-tree -p a -p b -m "merge b into a" "$(git show -s --pretty=format:%T b)")"
# And update the branch to point to that commit
git update-ref refs/heads/a "$commit"

I would use tel: (as recommended). But to have a better fallback/not display error pages I would use something like this (using jquery):

// enhance tel-links
$("a[href^='tel:']").each(function() {
    var target = "call-" + this.href.replace(/[^a-z0-9]*/gi, "");
    var link = this;

    // load in iframe to supress potential errors when protocol is not available
    $("body").append("<iframe name=\"" + target + "\" style=\"display: none\"></iframe>");
    link.target = target;

    // replace tel with callto on desktop browsers for skype fallback
    if (!navigator.userAgent.match(/(mobile)/gi)) {
        link.href = link.href.replace(/^tel:/, "callto:");
    }
});

The assumption is, that mobile browsers that have a mobile stamp in the userAgent-string have support for the tel: protocol. For the rest we replace the link with the callto: protocol to have a fallback to Skype where available.

To suppress error-pages for the unsupported protocol(s), the link is targeted to a new hidden iframe.

Unfortunately it does not seem to be possible to check, if the url has been loaded successfully in the iframe. It's seems that no error events are fired.

Sometimes two classes may have some parameter names in common. In that case, you can't pop the key-value pairs off of **kwargs or remove them from *args. Instead, you can define a Base class which unlike object, absorbs/ignores arguments:

class Base(object):
    def __init__(self, *args, **kwargs): pass

class A(Base):
    def __init__(self, *args, **kwargs):
        print "A"
        super(A, self).__init__(*args, **kwargs)

class B(Base):
    def __init__(self, *args, **kwargs):
        print "B"
        super(B, self).__init__(*args, **kwargs)

class C(A):
    def __init__(self, arg, *args, **kwargs):
        print "C","arg=",arg
        super(C, self).__init__(arg, *args, **kwargs)

class D(B):
    def __init__(self, arg, *args, **kwargs):
        print "D", "arg=",arg
        super(D, self).__init__(arg, *args, **kwargs)

class E(C,D):
    def __init__(self, arg, *args, **kwargs):
        print "E", "arg=",arg
        super(E, self).__init__(arg, *args, **kwargs)

print "MRO:", [x.__name__ for x in E.__mro__]
E(10)

yields

MRO: ['E', 'C', 'A', 'D', 'B', 'Base', 'object']
E arg= 10
C arg= 10
A
D arg= 10
B

Note that for this to work, Base must be the penultimate class in the MRO.

Goto xampp folder in local drive c, click on mysql folder, then click on bin and finally click on "mysqladmin" application. Then go back and refresh your browser and the problem is solved.

After struggling with this myself, I've come to implement FileReader for browsers that support it (Chrome, Firefox and the as-yet unreleased Safari 6), and a PHP script that echos back POSTed file data as Base64-encoded data for the other browsers.

This error occurs on the server side when the client closed the socket connection before the response could be returned over the socket. In a web app scenario not all of these are dangerous, since they can be created manually. For example, by quitting the browser before the reponse was retrieved.

Unfortunately, re.escape() is not suited for the replacement string:

>>> re.sub('a', re.escape('_'), 'aa')
'\\_\\_'

A solution is to put the replacement in a lambda:

>>> re.sub('a', lambda _: '_', 'aa')
'__'

because the return value of the lambda is treated by re.sub() as a literal string.

You can also create a batch file like the following if you need finer granularity between calls:

:loop
CallYour.Exe
timeout /t timeToWaitBetweenCallsInSeconds /nobreak
goto :loop

You can use getContent() method on Request object.

$request->getContent() //json as a string.

Update: Index of Nth occurance one-liner:

int NthOccurence(string s, char t, int n)
{
    s.TakeWhile(c => n - (c == t)?1:0 > 0).Count();
}

Use these at your own risk. This looks like homework, so I left a few bugs in there for your to find:

int CountChars(string s, char t)
{
   int count = 0;
   foreach (char c in s)
      if (s.Equals(t)) count ++;
   return count;
}

.

int CountChars(string s, char t)
{
     return s.Length - s.Replace(t.ToString(), "").Length;
}

.

int CountChars(string s, char t)
{
    Regex r = new Regex("[\\" + t + "]");
    return r.Match(s).Count;
}

Adding to @mob's answer:

Appending %N to date +%s gives us nanosecond accuracy:

start=`date +%s%N`;<command>;end=`date +%s%N`;echo `expr $end - $start`

There's a standard Windows component which can achieve what you're trying to do: BITS. It has been included in Windows since XP and 2000 SP3.

Run:

bitsadmin.exe /transfer "JobName" http://download.url/here.exe C:\destination\here.exe

The job name is simply the display name for the download job - set it to something that describes what you're doing.

In my case the issue seemed due to ajax delays but was related to internal iframes inside the main page. In seleminum it is possible to switch to internal frames with:

    driver.switchTo().frame("body");
    driver.switchTo().frame("bodytab");

I use java. After that I was able to locate the element

    driver.findElement(By.id("e_46")).click();

You are creating those bytes objects yourself:

item['title'] = [t.encode('utf-8') for t in title]
item['link'] = [l.encode('utf-8') for l in link]
item['desc'] = [d.encode('utf-8') for d in desc]
items.append(item)

Each of those t.encode(), l.encode() and d.encode() calls creates a bytes string. Do not do this, leave it to the JSON format to serialise these.

Next, you are making several other errors; you are encoding too much where there is no need to. Leave it to the json module and the standard file object returned by the open() call to handle encoding.

You also don't need to convert your items list to a dictionary; it'll already be an object that can be JSON encoded directly:

class W3SchoolPipeline(object):    
    def __init__(self):
        self.file = open('w3school_data_utf8.json', 'w', encoding='utf-8')

    def process_item(self, item, spider):
        line = json.dumps(item) + '\n'
        self.file.write(line)
        return item

I'm guessing you followed a tutorial that assumed Python 2, you are using Python 3 instead. I strongly suggest you find a different tutorial; not only is it written for an outdated version of Python, if it is advocating line.decode('unicode_escape') it is teaching some extremely bad habits that'll lead to hard-to-track bugs. I can recommend you look at Think Python, 2nd edition for a good, free, book on learning Python 3.

Think of DIV as a grouping element. You put elements in a DIV element so that you can set their alignments

Whereas "p" is simply to create a new paragraph.

Try this test:

any(substring in string for substring in substring_list)

It will return True if any of the substrings in substring_list is contained in string.

Note that there is a Python analogue of Marc Gravell's answer in the linked question:

from itertools import imap
any(imap(string.__contains__, substring_list)) 

In Python 3, you can use map directly instead:

any(map(string.__contains__, substring_list))

Probably the above version using a generator expression is more clear though.

VLC should be able to do this.

You are referring to the type rather than the instance. Make 'Model' lowercase in the example in your second and fourth code samples.

Model.GetHtmlAttributes

should be

model.GetHtmlAttributes

Add below setting to .eslintrc.js / .eslintrc.json to ignore these errors:

  rules: {
    // suppress errors for missing 'import React' in files
   "react/react-in-jsx-scope": "off",
    // allow jsx syntax in js files (for next.js project)
   "react/jsx-filename-extension": [1, { "extensions": [".js", ".jsx"] }], //should add ".ts" if typescript project
  }

Why? If you're using NEXT.js then you do not require to import React at top of files, nextjs does that for you.

Nothing like these two lines appears in Mike Williams' tutorial:

    wait = true;
    setTimeout("wait = true", 2000);

Here's a Version 3 port:

The relevant bit of code is

  // ====== Geocoding ======
  function getAddress(search, next) {
    geo.geocode({address:search}, function (results,status)
      { 
        // If that was successful
        if (status == google.maps.GeocoderStatus.OK) {
          // Lets assume that the first marker is the one we want
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          // Output the data
            var msg = 'address="' + search + '" lat=' +lat+ ' lng=' +lng+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;
          // Create a marker
          createMarker(search,lat,lng);
        }
        // ====== Decode the error status ======
        else {
          // === if we were sending the requests to fast, try this one again and increase the delay
          if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            nextAddress--;
            delay++;
          } else {
            var reason="Code "+status;
            var msg = 'address="' + search + '" error=' +reason+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;
          }   
        }
        next();
      }
    );
  }

Tomcat is a web server (can handle HTTP requests/responses) and web container (implements Java Servlet API, also called servletcontainer) in one. Some may call it an application server, but it is definitely not an fullfledged Java EE application server (it does not implement the whole Java EE API).

See also:

• What exactly is Java EE?
• How do servlets work? Instantiation, sessions, shared variables and multithreading

By Default the InternetExplorerDriver listens on port "5555". Change your huburl to match that. you can look on the cmd box window to confirm.

When you are using ui-router, you should not use ng-controller anywhere. Your controllers are automatically instantiated for a ui-view when their appropriate states are activated.

You can index Dictionary, you didn't need 'get'.

Dictionary<string,string> example = new Dictionary<string,string>();
...
example.Add("hello","world");
...
Console.Writeline(example["hello"]);

An efficient way to test/get values is TryGetValue (thanx to Earwicker):

if (otherExample.TryGetValue("key", out value))
{
    otherExample["key"] = value + 1;
}

With this method you can fast and exception-less get values (if present).

You can blur the body background image by using the body's :before pseudo class to inherit the image and then blurring it. Wrap all that into a class and use javascript to add and remove the class to blur and unblur.

Next is a piece of code which uses csv module but extracts file.csv contents to a list of dicts using the first line which is a header of csv table

import csv
def csv2dicts(filename):
  with open(filename, 'rb') as f:
    reader = csv.reader(f)
    lines = list(reader)
    if len(lines) < 2: return None
    names = lines[0]
    if len(names) < 1: return None
    dicts = []
    for values in lines[1:]:
      if len(values) != len(names): return None
      d = {}
      for i,_ in enumerate(names):
        d[names[i]] = values[i]
      dicts.append(d)
    return dicts
  return None

if __name__ == '__main__':
  your_list = csv2dicts('file.csv')
  print your_list

all is one option:

> A <- c("A", "B", "C", "D")
> B <- A
> C <- c("A", "C", "C", "E")

> all(A==B)
[1] TRUE
> all(A==C)
[1] FALSE

But you may have to watch out for recycling:

> D <- c("A","B","A","B")
> E <- c("A","B")
> all(D==E)
[1] TRUE
> all(length(D)==length(E)) && all(D==E)
[1] FALSE

The documentation for length says it currently only outputs an integer of length 1, but that it may change in the future, so that's why I wrapped the length test in all.

Have you tried using the MD5 implementation in hashlib? Note that hashing algorithms typically act on binary data rather than text data, so you may want to be careful about which character encoding is used to convert from text to binary data before hashing.

The result of a hash is also binary data - it looks like Flickr's example has then been converted into text using hex encoding. Use the hexdigest function in hashlib to get this.

Side Note: Starting at rails 5.0.0 rake has been changed to rails So perform the following

A modification of the code by @CarloCannas:

public static void sudo(String...strings) {
    try{
        Process su = Runtime.getRuntime().exec("su");
        DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        outputStream.close();
    }catch(IOException e){
        e.printStackTrace();
    }
}

(You are welcome to find a better place for outputStream.close())

Usage example:

private static void suMkdirs(String path) {
    if (!new File(path).isDirectory()) {
        sudo("mkdir -p "+path);
    }
}

Update: To get the result (the output to stdout), use:

public static String sudoForResult(String...strings) {
    String res = "";
    DataOutputStream outputStream = null;
    InputStream response = null;
    try{
        Process su = Runtime.getRuntime().exec("su");
        outputStream = new DataOutputStream(su.getOutputStream());
        response = su.getInputStream();

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        res = readFully(response);
    } catch (IOException e){
        e.printStackTrace();
    } finally {
        Closer.closeSilently(outputStream, response);
    }
    return res;
}
public static String readFully(InputStream is) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int length = 0;
    while ((length = is.read(buffer)) != -1) {
        baos.write(buffer, 0, length);
    }
    return baos.toString("UTF-8");
}

The utility to silently close a number of Closeables (So?ket may be no Closeable) is:

public class Closer {
// closeAll()
public static void closeSilently(Object... xs) {
    // Note: on Android API levels prior to 19 Socket does not implement Closeable
    for (Object x : xs) {
        if (x != null) {
            try {
                Log.d("closing: "+x);
                if (x instanceof Closeable) {
                    ((Closeable)x).close();
                } else if (x instanceof Socket) {
                    ((Socket)x).close();
                } else if (x instanceof DatagramSocket) {
                    ((DatagramSocket)x).close();
                } else {
                    Log.d("cannot close: "+x);
                    throw new RuntimeException("cannot close "+x);
                }
            } catch (Throwable e) {
                Log.x(e);
            }
        }
    }
}
}

I have one more solution to do this

Using Ajax in javascript

here is the explained code in Github repo https://github.com/dupinder/staticHTML-Include

basic idea is:

index.html

<!DOCTYPE html>
<html>
<head>
    <meta charset='utf-8'>
    <meta http-equiv='X-UA-Compatible' content='IE=edge'>
    <title>Page Title</title>
    <meta name='viewport' content='width=device-width, initial-scale=1'>
    <script src='main.js'></script>


</head>
<body>
    <header></header>

    <footer></footer>
</body>
</html>

main.js

fetch("./header.html")
  .then(response => {
    return response.text()
  })
  .then(data => {
    document.querySelector("header").innerHTML = data;
  });

fetch("./footer.html")
  .then(response => {
    return response.text()
  })
  .then(data => {
    document.querySelector("footer").innerHTML = data;
  });

It is possible. Have a look at JSch.addIdentity(...)

This allows you to use key either as byte array or to read it from file.

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class UserAuthPubKey {
    public static void main(String[] arg) {
        try {
            JSch jsch = new JSch();

            String user = "tjill";
            String host = "192.18.0.246";
            int port = 10022;
            String privateKey = ".ssh/id_rsa";

            jsch.addIdentity(privateKey);
            System.out.println("identity added ");

            Session session = jsch.getSession(user, host, port);
            System.out.println("session created.");

            // disabling StrictHostKeyChecking may help to make connection but makes it insecure
            // see http://stackoverflow.com/questions/30178936/jsch-sftp-security-with-session-setconfigstricthostkeychecking-no
            //

            // config.put("StrictHostKeyChecking", "no");
            // session.setConfig(config);

            session.connect();
            System.out.println("session connected.....");

            Channel channel = session.openChannel("sftp");
            channel.setInputStream(System.in);
            channel.setOutputStream(System.out);
            channel.connect();
            System.out.println("shell channel connected....");

            ChannelSftp c = (ChannelSftp) channel;

            String fileName = "test.txt";
            c.put(fileName, "./in/");
            c.exit();
            System.out.println("done");

        } catch (Exception e) {

        }
    }
}

You must float left all elements like so:

.form-group,
.form-group label,
.form-group input { float:left; display:inline;   }

give some margin to the desired elements :

 .form-group { margin-right:5px }

and set the label the same line height as the height of the fields:

.form-group label { line-height:--px; }

Type a value in one cell (EX:B4 CELL). For temporary use this formula in other cell (once done delete it). =CONCAT(XY,B4) . click and drag till the value you need. Copy the whole column and right click paste only values (second option).

I tried and it's working as expected.

You can find what you want in windows by looking with the windows dir command, use the administrator account to make it easy:

c:>dir wsdl.exe /s

Using Google Collections, assuming K is your key type:

Maps.filterKeys(treeMap, new Predicate<K>() {
  @Override
  public boolean apply(K key) {
    return false; //return true here if you need the entry to be in your new map
  }});

You can use filterEntries instead if you need the value as well.

Got the same error when tried to export a large Excel file (~150.000 rows) Fixed with the following code

Application xlApp = new Application();
xlApp.DefaultSaveFormat = XlFileFormat.xlOpenXMLWorkbook;

Just create a new theme in res/values/styles.xml where you change the "colorPrimaryDark" which is the color of the status bar:

<style name="AppTheme.GrayStatusBar" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimaryDark">@color/colorGray</item>
</style>

And modify the activity theme in AndroidManifest.xml to the one you want, on the next activity you can change the color back to the original one by selecting the original theme:

<activity
    android:name=".LoginActivity"
    android:theme="@style/AppTheme.GrayStatusBar" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

This is how your res/values/colors.xml should look like:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#3F51B5</color>
    <color name="colorPrimaryDark">#303F9F</color>
    <color name="colorAccent">#c6d6f0</color>
    <color name="colorGray">#757575</color>
</resources>

You can do the following:

df =DataFrame({'a':[1,2,3,4],'b':[2,4,6,8]})

df['x']=df.a + df.b
df['y']=df.a - df.b

create column title whatever order you want in this way:

column_titles = ['x','y','a','b']

df.reindex(columns=column_titles)

This will give you desired output

There are definitely uses for iframes folks. How else would you put the weather networks widget on your page? The only other way is to grab their XML and parse it, but then of course you need conditions to throw up the pertenant weather graphics... not really worth it, but way cleaner if you have the time.

I've tried the code from above and made my own shadow which is little bit closer to what I am trying to achieve. Maybe it will help others too.

Here's a simple function that creates a CSS color string from RGB values ranging from 0 to 255:

function rgb(r, g, b){
  return "rgb("+r+","+g+","+b+")";
}

Alternatively (to create fewer string objects), you could use array join():

function rgb(r, g, b){
  return ["rgb(",r,",",g,",",b,")"].join("");
}

The above functions will only work properly if (r, g, and b) are integers between 0 and 255. If they are not integers, the color system will treat them as in the range from 0 to 1. To account for non-integer numbers, use the following:

function rgb(r, g, b){
  r = Math.floor(r);
  g = Math.floor(g);
  b = Math.floor(b);
  return ["rgb(",r,",",g,",",b,")"].join("");
}

You could also use ES6 language features:

const rgb = (r, g, b) => 
  `rgb(${Math.floor(r)},${Math.floor(g)},${Math.floor(b)})`;

instead of g++ you have to write gcc-c++

sudo dnf install gcc-c++

On Linux use below to test (it would replace the whitespaces with comma)

 sed 's/\s/,/g' /tmp/test.txt | head

later you can take the output into the file using below command:

sed 's/\s/,/g' /tmp/test.txt > /tmp/test_final.txt

PS: test is the file which you want to use

Ok I wonder when's the use but, here are two snipets you could use:

lastlog.cmd

@echo off
for /f "delims=" %%l in (log.txt) do set TimeStamp=%%l
echo %TimeStamp%

Change the "echo.." line, but the last log time is within %TimeStamp%. No temp files used, no clutter and reusable as it is in a variable.

On the other hand, if you need to know this WITHIN your code, and not from another batch, change your logging for:

set TimeStamp=%date%, %time%
echo %TimeStamp% >> log.txt

so that the variable %TimeStamp% is usable later when you need it.

tl;dr version: use ~/.zshrc

And read the man page to understand the differences between:

~/.zshrc, ~/.zshenv and ~/.zprofile.

Regarding my comment

In my comment attached to the answer kev gave, I said:

This seems to be incorrect - /etc/profile isn't listed in any zsh documentation I can find.

This turns out to be partially incorrect: /etc/profile may be sourced by zsh. However, this only occurs if zsh is "invoked as sh or ksh"; in these compatibility modes:

The usual zsh startup/shutdown scripts are not executed. Login shells source /etc/profile followed by $HOME/.profile. If the ENV environment variable is set on invocation, $ENV is sourced after the profile scripts. The value of ENV is subjected to parameter expansion, command substitution, and arithmetic expansion before being interpreted as a pathname. [man zshall, "Compatibility"].

The ArchWiki ZSH link says:

At login, Zsh sources the following files in this order:
/etc/profile
This file is sourced by all Bourne-compatible shells upon login

This implys that /etc/profile is always read by zsh at login - I haven't got any experience with the Arch Linux project; the wiki may be correct for that distribution, but it is not generally correct. The information is incorrect compared to the zsh manual pages, and doesn't seem to apply to zsh on OS X (paths in $PATH set in /etc/profile do not make it to my zsh sessions).

To address the question:

where exactly should I be placing my rvm, python, node etc additions to my $PATH?

Generally, I would export my $PATH from ~/.zshrc, but it's worth having a read of the zshall man page, specifically the "STARTUP/SHUTDOWN FILES" section - ~/.zshrc is read for interactive shells, which may or may not suit your needs - if you want the $PATH for every zsh shell invoked by you (both interactive and not, both login and not, etc), then ~/.zshenv is a better option.

Is there a specific file I should be using (i.e. .zshenv which does not currently exist in my installation), one of the ones I am currently using, or does it even matter?

There's a bunch of files read on startup (check the linked man pages), and there's a reason for that - each file has it's particular place (settings for every user, settings for user-specific, settings for login shells, settings for every shell, etc).
Don't worry about ~/.zshenv not existing - if you need it, make it, and it will be read.

.bashrc and .bash_profile are not read by zsh, unless you explicitly source them from ~/.zshrc or similar; the syntax between bash and zsh is not always compatible. Both .bashrc and .bash_profile are designed for bash settings, not zsh settings.

There is no need to use foreign libraries.

Convert a BitmapImage to Bitmap:

private Bitmap BitmapImage2Bitmap(BitmapImage bitmapImage)
{
    // BitmapImage bitmapImage = new BitmapImage(new Uri("../Images/test.png", UriKind.Relative));

    using(MemoryStream outStream = new MemoryStream())
    {
        BitmapEncoder enc = new BmpBitmapEncoder();
        enc.Frames.Add(BitmapFrame.Create(bitmapImage));
        enc.Save(outStream);
        System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(outStream);

        return new Bitmap(bitmap);
    }
}

To convert the Bitmap back to a BitmapImage:

[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern bool DeleteObject(IntPtr hObject);

private BitmapImage Bitmap2BitmapImage(Bitmap bitmap)
{
    IntPtr hBitmap = bitmap.GetHbitmap();
    BitmapImage retval;

    try
    {
        retval = (BitmapImage)Imaging.CreateBitmapSourceFromHBitmap(
                     hBitmap,
                     IntPtr.Zero,
                     Int32Rect.Empty,
                     BitmapSizeOptions.FromEmptyOptions());
    }
    finally
    {
        DeleteObject(hBitmap);
    }

    return retval;
}

We use compiled code to distribute to users who do not have access to the source code. Basically to stop inexperienced programers accidentally changing something or fixing bugs without telling us.

Swift 4

    let calendar = Calendar.current
    let time=calendar.dateComponents([.hour,.minute,.second], from: Date())
    print("\(time.hour!):\(time.minute!):\(time.second!)")

I use micro-util class for getting last (and first) element of list:

public final class Lists {

    private Lists() {
    }

    public static <T> T getFirst(List<T> list) {
        return list != null && !list.isEmpty() ? list.get(0) : null;
    }

    public static <T> T getLast(List<T> list) {
        return list != null && !list.isEmpty() ? list.get(list.size() - 1) : null;
    }
}

Slightly more flexible:

import java.util.List;

/**
 * Convenience class that provides a clearer API for obtaining list elements.
 */
public final class Lists {

  private Lists() {
  }

  /**
   * Returns the first item in the given list, or null if not found.
   *
   * @param <T> The generic list type.
   * @param list The list that may have a first item.
   *
   * @return null if the list is null or there is no first item.
   */
  public static <T> T getFirst( final List<T> list ) {
    return getFirst( list, null );
  }

  /**
   * Returns the last item in the given list, or null if not found.
   *
   * @param <T> The generic list type.
   * @param list The list that may have a last item.
   *
   * @return null if the list is null or there is no last item.
   */
  public static <T> T getLast( final List<T> list ) {
    return getLast( list, null );
  }

  /**
   * Returns the first item in the given list, or t if not found.
   *
   * @param <T> The generic list type.
   * @param list The list that may have a first item.
   * @param t The default return value.
   *
   * @return null if the list is null or there is no first item.
   */
  public static <T> T getFirst( final List<T> list, final T t ) {
    return isEmpty( list ) ? t : list.get( 0 );
  }

  /**
   * Returns the last item in the given list, or t if not found.
   *
   * @param <T> The generic list type.
   * @param list The list that may have a last item.
   * @param t The default return value.
   *
   * @return null if the list is null or there is no last item.
   */
  public static <T> T getLast( final List<T> list, final T t ) {
    return isEmpty( list ) ? t : list.get( list.size() - 1 );
  }

  /**
   * Returns true if the given list is null or empty.
   *
   * @param <T> The generic list type.
   * @param list The list that has a last item.
   *
   * @return true The list is empty.
   */
  public static <T> boolean isEmpty( final List<T> list ) {
    return list == null || list.isEmpty();
  }
}

After speaking with you in the comments, I believe that you can just do this using numpy/scipy. The ideas is to read the image in the numpy 3d-array and feed it into the variable.

from scipy import misc
import tensorflow as tf

img = misc.imread('01.png')
print img.shape    # (32, 32, 3)

img_tf = tf.Variable(img)
print img_tf.get_shape().as_list()  # [32, 32, 3]

Then you can run your graph:

init = tf.initialize_all_variables()
sess = tf.Session()
sess.run(init)
im = sess.run(img_tf)

and verify that it is the same:

import matplotlib.pyplot as plt
fig = plt.figure()
fig.add_subplot(1,2,1)
plt.imshow(im)
fig.add_subplot(1,2,2)
plt.imshow(img)
plt.show()

P.S. you mentioned: Since it's supposed to parallelize reading, it seems useful to know.. To which I can say that rarely in data-analysis reading of the data is the bottleneck. Most of your time you will spend training your model.

If you want a window as a whole to have a specific size, you can just give it the size you want with the geometry command. That's really all you need to do.

For example:

mw.geometry("500x500")

Though, you'll also want to make sure that the widgets inside the window resize properly, so change how you add the frame to this:

back.pack(fill="both", expand=True)

The solution I came up with is fragile; it relies on django's naming convention for foreign keys.

USE information_schema;
tee mysql_output
SELECT * FROM TABLE_CONSTRAINTS WHERE CONSTRAINT_TYPE = 'FOREIGN KEY' AND TABLE_SCHEMA = 'database_name';
notee

Then, in the shell,

grep 'refs_tablename_id' mysql_output

Something I did recently, hope it helps. I have a list of dictionaries and wanted to add a value to some existing documents.

for item in my_list:
    my_collection.update({"_id" : item[key] }, {"$set" : {"New_col_name" :item[value]}})

You may compiling your program while another program may be running in background. Firstly, see if another program is running .Close it and then try ro compile.

Instead of if-else condition use if in both conditions. it will work that way but not sure why.

@Egidius, when creating an XMLHttpRequest, you should use

var xhr = new XMLHttpRequest({mozSystem: true});

What is mozSystem?

mozSystem Boolean: Setting this flag to true allows making cross-site connections without requiring the server to opt-in using CORS. Requires setting mozAnon: true, i.e. this can't be combined with sending cookies or other user credentials. This only works in privileged (reviewed) apps; it does not work on arbitrary webpages loaded in Firefox.

Changes to your Manifest

On your manifest, do not forget to include this line on your permissions:

"permissions": {
       "systemXHR" : {},
}

I was making a drop-down menu for a language selector - but I needed the dropdown menu to display the current language upon page load. I would either be getting my initial language from a URL param example.com?user_language=fr, or detecting it from the user’s browser settings. Then when the user interacted with the dropdown, the selected language would be updated and the language selector dropdown would display the currently selected language.

Since this whole thread has been giving fruit examples, I got all sorts of fruit goodness for you.

• First up, answering the initially asked question with a basic React functional component - two examples with and without props, then how to import the component elsewhere.

• Next up, the same example - but juiced up with Typescript.

• Then a bonus finale - A language selector dropdown component using Typescript.

Basic React (16.13.1) Functional Component Example. Two examples of FruitSelectDropdown , one without props & one with accepting props fruitDetector

import React, { useState } from 'react'

export const FruitSelectDropdown = () => {
  const [currentFruit, setCurrentFruit] = useState('oranges')
  
  const changeFruit = (newFruit) => {
    setCurrentFruit(newFruit)
  }
  
  return (
    <form>
      <select 
        onChange={(event) => changeFruit(event.target.value)}
        value={currentFruit}
      >
        <option value="apples">Red Apples</option>
        <option value="oranges">Outrageous Oranges</option>
        <option value="tomatoes">Technically a Fruit Tomatoes</option>
        <option value="bananas">Bodacious Bananas</option>
      </select>
    </form>
  )
}

Or you can have FruitSelectDropdown accept props, maybe you have a function that outputs a string, you can pass it through using the fruitDetector prop

import React, { useState } from 'react'

export const FruitSelectDropdown = ({ fruitDetector }) => {
  const [currentFruit, setCurrentFruit] = useState(fruitDetector)
  
  const changeFruit = (newFruit) => {
    setCurrentFruit(newFruit)
  }
  
  return (
    <form>
      <select 
        onChange={(event) => changeFruit(event.target.value)}
        value={currentFruit}
      >
        <option value="apples">Red Apples</option>
        <option value="oranges">Outrageous Oranges</option>
        <option value="tomatoes">Technically a Fruit Tomatoes</option>
        <option value="bananas">Bodacious Bananas</option>
      </select>
    </form>
  )
}

Then import the FruitSelectDropdown elsewhere in your app

import React from 'react'
import { FruitSelectDropdown } from '../path/to/FruitSelectDropdown'

const App = () => {
  return (
    <div className="page-container">
      <h1 className="header">A webpage about fruit</h1>
      <div className="section-container">
        <h2>Pick your favorite fruit</h2>
        <FruitSelectDropdown fruitDetector='bananas' />

      </div>
    </div>
  )
}

export default App

FruitSelectDropdown with Typescript

import React, { FC, useState } from 'react'

type FruitProps = {
  fruitDetector: string;
}

export const FruitSelectDropdown: FC<FruitProps> = ({ fruitDetector }) => {
  const [currentFruit, setCurrentFruit] = useState(fruitDetector)
  
  const changeFruit = (newFruit: string): void => {
    setCurrentFruit(newFruit)
  }
  
  return (
    <form>
      <select 
        onChange={(event) => changeFruit(event.target.value)}
        value={currentFruit}
      >
        <option value="apples">Red Apples</option>
        <option value="oranges">Outrageous Oranges</option>
        <option value="tomatoes">Technically a Fruit Tomatoes</option>
        <option value="bananas">Bodacious Bananas</option>
      </select>
    </form>
  )
}

Then import the FruitSelectDropdown elsewhere in your app

Here is a class 'getJ' with a static function 'chr()'. This function reads one char.

import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;

class getJ {
    static char  chr()throws IOException{  
        BufferedReader bufferReader =new BufferedReader(new InputStreamReader(System.in));
        return bufferReader.readLine().charAt(0);
    }
}

In order to read a char use this:

anyFunc()throws IOException{
...
...
char c=getJ.chr();
}

Because of 'chr()' is static, you don't have to create 'getJ' by 'new' ; I mean you don't need to do:

getJ ob = new getJ;
c=ob.chr();

You should remember to add 'throws IOException' to the function's head. If it's impossible, use try / catch as follows:

anyFunc(){// if it's impossible to add 'throws IOException' here
...
try
{
char c=getJ.chr(); //reads a char into c
} 
catch(IOException e)
{
System.out.println("IOException has been caught");
}

If the problem you face is the menu breaking into multiple lines, you can try one of the following:

1) Try to reduce the number of menu items or their length, like removing menu items or shortening the words.

2) Reducing the padding between the menu items, like this:

.navbar .nav > li > a {
padding: 10px 15px 10px; /* Change here the second value for padding-left and padding right */
}

Default padding is 15px both sides (left and right).

If you prefer to change each individual side use:

padding-left: 7px; 
padding-right: 8px;

This setting affects the dropdown list too.

This doesn't answer the question but it could help others who don't want to mess with the CSS or using LESS variables. The two common approaches to solve this problem.

UPDATE: In Oracle 12c onward we have an option to create auto increment field, its better than trigger and sequence.

• Right click on the table and select "Edit".
• In "Edit" Table window, select "columns", and then select your PK column.
• Go to Identity Column tab and select "Generated as Identity" as Type, put 1 in both start with and increment field. This will make this column auto increment.

See the below image

From SQL Statement

IDENTITY column is now available on Oracle 12c:

 create table t1 (
     c1 NUMBER GENERATED by default on null as IDENTITY,
     c2 VARCHAR2(10)
     );

or specify starting and increment values, also preventing any insert into the identity column (GENERATED ALWAYS) (again, Oracle 12c+ only)

create table t1 (
    c1 NUMBER GENERATED ALWAYS as IDENTITY(START with 1 INCREMENT by 1),
    c2 VARCHAR2(10)
    );

EDIT : if you face any error like "ORA-30673: column to be modified is not an identity column", then you need to create new column and delete the old one.

Use scanf("%d",&rows) instead of scanf("%s",input)

This allow you to get direcly the integer value from stdin without need to convert to int.

If the user enter a string containing a non numeric characters then you have to clean your stdin before the next scanf("%d",&rows).

your code could look like this:

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

int clean_stdin()
{
    while (getchar()!='\n');
    return 1;
}

int main(void)  
{ 
    int rows =0;  
    char c;
    do
    {  
        printf("\nEnter an integer from 1 to 23: ");

    } while (((scanf("%d%c", &rows, &c)!=2 || c!='\n') && clean_stdin()) || rows<1 || rows>23);

    return 0;  
}

Explanation

1)

scanf("%d%c", &rows, &c)

This means expecting from the user input an integer and close to it a non numeric character.

Example1: If the user enter aaddk and then ENTER, the scanf will return 0. Nothing capted

Example2: If the user enter 45 and then ENTER, the scanf will return 2 (2 elements are capted). Here %d is capting 45 and %c is capting \n

Example3: If the user enter 45aaadd and then ENTER, the scanf will return 2 (2 elements are capted). Here %d is capting 45 and %c is capting a

2)

(scanf("%d%c", &rows, &c)!=2 || c!='\n')

In the example1: this condition is TRUE because scanf return 0 (!=2)

In the example2: this condition is FALSE because scanf return 2 and c == '\n'

In the example3: this condition is TRUE because scanf return 2 and c == 'a' (!='\n')

3)

((scanf("%d%c", &rows, &c)!=2 || c!='\n') && clean_stdin())

clean_stdin() is always TRUE because the function return always 1

In the example1: The (scanf("%d%c", &rows, &c)!=2 || c!='\n') is TRUE so the condition after the && should be checked so the clean_stdin() will be executed and the whole condition is TRUE

In the example2: The (scanf("%d%c", &rows, &c)!=2 || c!='\n') is FALSE so the condition after the && will not checked (because what ever its result is the whole condition will be FALSE ) so the clean_stdin() will not be executed and the whole condition is FALSE

In the example3: The (scanf("%d%c", &rows, &c)!=2 || c!='\n') is TRUE so the condition after the && should be checked so the clean_stdin() will be executed and the whole condition is TRUE

So you can remark that clean_stdin() will be executed only if the user enter a string containing non numeric character.

And this condition ((scanf("%d%c", &rows, &c)!=2 || c!='\n') && clean_stdin()) will return FALSE only if the user enter an integer and nothing else

And if the condition ((scanf("%d%c", &rows, &c)!=2 || c!='\n') && clean_stdin()) is FALSE and the integer is between and 1 and 23 then the while loop will break else the while loop will continue

var res = (from element in list)
      .OrderBy(x => x.F2).AsEnumerable()
      .GroupBy(x => x.F1)
      .Select()

Use .AsEnumerable() after OrderBy()

This was asked on the www-style list, and Tab Atkins (spec editor) provided an answer explaining why. I'll elaborate on that a bit here.

To start out, let's initially assume our flex container is single-line (flex-wrap: nowrap). In this case, there's clearly an alignment difference between the main axis and the cross axis -- there are multiple items stacked in the main axis, but only one item stacked in the cross axis. So it makes sense to have a customizeable-per-item "align-self" in the cross axis (since each item is aligned separately, on its own), whereas it doesn't make sense in the main axis (since there, the items are aligned collectively).

For multi-line flexbox, the same logic applies to each "flex line". In a given line, items are aligned individually in the cross axis (since there's only one item per line, in the cross axis), vs. collectively in the main axis.

Here's another way of phrasing it: so, all of the *-self and *-content properties are about how to distribute extra space around things. But the key difference is that the *-self versions are for cases where there's only a single thing in that axis, and the *-content versions are for when there are potentially many things in that axis. The one-thing vs. many-things scenarios are different types of problems, and so they have different types of options available -- for example, the space-around / space-between values make sense for *-content, but not for *-self.

SO: In a flexbox's main axis, there are many things to distribute space around. So a *-content property makes sense there, but not a *-self property.

In contrast, in the cross axis, we have both a *-self and a *-content property. One determines how we'll distribute space around the many flex lines (align-content), whereas the other (align-self) determines how to distribute space around individual flex items in the cross axis, within a given flex line.

(I'm ignoring *-items properties here, since they simply establish defaults for *-self.)

Use Encoding.Convert to adjust the byte array before attempting to decode it into your destination encoding.

Encoding iso = Encoding.GetEncoding("ISO-8859-1");
Encoding utf8 = Encoding.UTF8;
byte[] utfBytes = utf8.GetBytes(Message);
byte[] isoBytes = Encoding.Convert(utf8, iso, utfBytes);
string msg = iso.GetString(isoBytes);

It's even easier to use parent > child selector relationship so the inner div do not need to have their css classes to be defined explicitly:

.display-table {_x000D_
    display: table; _x000D_
}_x000D_
.display-table > div { _x000D_
    display: table-row; _x000D_
}_x000D_
.display-table > div > div { _x000D_
    display: table-cell;_x000D_
    padding: 5px;_x000D_
}

<div class="display-table">_x000D_
    <div>_x000D_
        <div>0, 0</div>_x000D_
        <div>0, 1</div>_x000D_
    </div>_x000D_
    <div>_x000D_
        <div>1, 0</div>_x000D_
        <div>1, 1</div>_x000D_
    </div>_x000D_

Install Multiple Versions Of Xcode using the Xcode-Install Ruby Gem

You can do this whole process a lot easier if you use the xcode-install RubyGem.

If you already have a working installation of the Xcode CommandLineTools and Ruby (I'd suggest using Homebrew for installing Ruby) but I think it works with the Ruby supplied by macOS as well if you install the Gem either using sudo or as a user install. (Details on the GitHub page) Basically:

    $ gem install xcode-install
    $ xcversion list
    6.0.1
    6.1
    6.1.1
    6.2 (installed)
    6.3
    $ xcversion install 8
    ######################################################################## 100.0%
    Please authenticate for Xcode installation...

    Xcode 8
    Build version 6D570

To select a version as active, you'll run:
$ xcversion select 8

To select a version as active and change the symlink at /Applications/Xcode, you'll run:
$ xcversion select 8 --symlink

xcode-install can also manage your local simulators using the simulators command.

Read the instructions on the GitHub Project page for more info.

Here's the lowdown on Mac IDE's for PHP

NetBeans Free! Plus, the best functionality of all offerings. Includes inline database connections, code completion, syntax checking, color coding, split views etc. Downside: It's a memory hog on the Mac. Be prepared to allow half a gig of memory then you'll need to shut down and restart.

Komodo A step above a Text Editor. Does not support database connections or split views. Color coding and syntax checking are there to an extent. The project control on Komodo is very unwieldy and strange compared to the other IDEs.

Aptana The perfect solution. Eclipsed based and uses the Aptana PHP plug in. Real time syntax checking, word wrap, drag and drop split views, database connections and a slew of other excellent features. Downside: Not a supported product any more. Aptana Studio 2.0+ uses PDT which is a watered down, under-developed (at present) php plug in.

Zend Studio - Almost identical to Aptana, except no word wrap and you can't change alot of the php configuration on the MAC apparently due to bugs.

Coda Created by Panic, Coda has nice integration with source control and their popular FTP client, transmit. They also have a collaboration feature which is cool for pair-programming.

PhpEd with Parallels or Wine. The best IDE for Windows has all the feature you could need and is worth the effort to pass it through either Parallels or Wine.

Dreamweaver Good for Javascript/HTML/CSS, but only marginal for PHP. There is some color coding, but no syntax checking or code completion native to the package. Database connections are supported, and so are split views.

I'm using NetBeans, which is free, and feature rich. I can deal with the memory issues for a while, but it could be slow coming to the MAC.

I've experimented with typing "exit for" a few times and noticed it worked and VB didn't yell at me. It's an option I guess but it just looked bad.

I think the best option is similar to that shared by Tobias. Just put your code in a function and have it return when you want to break out of your loops. Looks cleaner too.

For Each item In itemlist
    For Each item1 In itemlist1
        If item1 = item Then
            Return item1
        End If
    Next
Next

Building on the previous answers to this question; the following function will split a string (str) n-number (size) of characters.

function chunk(str, size) {
    return str.match(new RegExp('.{1,' + size + '}', 'g'));
}

Create a .vbs file with this code:

CreateObject("Wscript.Shell").Run "your_batch.bat",0,True

This .vbs will run your_batch.bat hidden.

Works fine for me.

I encountered with same error and resolved it with redeployment after removing deployment.

In addition to the solution you accepted, you could also implement the special __lt__() ("less than") method on the class. The sort() method (and the sorted() function) will then be able to compare the objects, and thereby sort them. This works best when you will only ever sort them on this attribute, however.

class Foo(object):

     def __init__(self, score):
         self.score = score

     def __lt__(self, other):
         return self.score < other.score

l = [Foo(3), Foo(1), Foo(2)]
l.sort()

string.Format("{0:yyyy-MM-ddTHH:mm:ss.FFFZ}", DateTime.UtcNow)

returns 2017-02-10T08:12:39.483Z

In my case I was having the same error and later I come to know that the 'condition' is mysql reserved keyword and I used that as field name.

{{ data.0 }} should work.

Let's say you wrote data.obj django tries data.obj and data.obj(). If they don't work it tries data["obj"]. In your case data[0] can be written as {{ data.0 }}. But I recommend you to pull data[0] in the view and send it as separate variable.

1) use for tommorow's date startDate: '+1d'

2) use for yesterday's date startDate: '-1d'

3) use for today's date startDate: new Date()

It is not possible to limit the number of visible elements in the select dropdown (if you use it as dropdown box and not as list).

But you could use javascript/jQuery to replace this selectbox with something else, which just looks like a dropdown box. Then you can handle the height of dropdown as you want.

jNice would be a jQuery plugin which has such features. But there also exists many alternatives for that.

If you want to UPSERT more than one record at a time you can use the ANSI SQL:2003 DML statement MERGE.

MERGE INTO table_name WITH (HOLDLOCK) USING table_name ON (condition)
WHEN MATCHED THEN UPDATE SET column1 = value1 [, column2 = value2 ...]
WHEN NOT MATCHED THEN INSERT (column1 [, column2 ...]) VALUES (value1 [, value2 ...])

Check out Mimicking MERGE Statement in SQL Server 2005.

exit code 139 (people say this means memory fragmentation)

No, it means that your program died with signal 11 (SIGSEGV on Linux and most other UNIXes), also known as segmentation fault.

Could anybody tell me why the run fails but debug doesn't?

Your program exhibits undefined behavior, and can do anything (that includes appearing to work correctly sometimes).

Your first step should be running this program under Valgrind, and fixing all errors it reports.

If after doing the above, the program still crashes, then you should let it dump core (ulimit -c unlimited; ./a.out) and then analyze that core dump with GDB: gdb ./a.out core; then use where command.

Try using ISNULL function:

SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 
INNER JOIN Table2
   ON Table1.Col1 = Table2.Col1 
   AND ISNULL(Table1.Col2, 'ZZZZ') = ISNULL(Table2.Col2,'ZZZZ')

Where 'ZZZZ' is some arbitrary value never in the table.

Loop through the file.

f = open("masters.txt")
lines = f.readlines()
for line in lines:
    print line

Our solution, adding some validations to response so we are sure we have a well formed json object in $json variable

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
curl_close($ch);
if (! $result) {
    return false;
}

$json = json_decode(utf8_encode($result));
if (empty($json) || json_last_error() !== JSON_ERROR_NONE) {
    return false;
}

Try:

int i = Convert.ToInt32(dt.Rows.Count);

I think it's the shortest, thus the simplest way.

Uncompyle6 works for Python 3.x and 2.7 - recommended option as it's most recent tool, aiming to unify earlier forks and focusing on automated unit testing. The GitHub page has more details.

• if you use Python 3.7+, you could also try decompile3, a fork of Uncompyle6 focusing on 3.7 and higher.
• do raise GitHub issues on these projects if needed - both run unit test suites on a range of Python versions

With these tools, you get your code back including variable names and docstrings, but without the comments.

The older Uncompyle2 supports Python 2.7 only. This worked well for me some time ago to decompile the .pyc bytecode into .py, whereas unpyclib crashed with an exception.

Just type the code and save it in .cpp format. then try "gcc filename.cpp" . This will create the object file. then try "./a.out" (This is the default object file name). If you want to know about gcc you can always try "man gcc"

To replace a string in your HTML with another use the replace method on innerHTML:

document.body.innerHTML = document.body.innerHTML.replace('hello', 'hi');

Note that this will replace the first instance of hello throughout the body, including any instances in your HTML code (e.g. class names etc..), so use with caution - for better results, try restricting the scope of your replacement by targeting your code using document.getElementById or similar.

To replace all instances of the target string, use a simple regular expression with the global flag:

document.body.innerHTML = document.body.innerHTML.replace(/hello/g, 'hi');

                return '/pages/' + urlattr.name + '.html';
            },
            controller: 'CMSController'
        });
    }
]);

• Adding * let you work with multiple levels of directories dynamically. Example: /page/cars/selling/list will be catch on this provider

From the docs (1.3.0):

"If templateUrl is a function, it will be called with the following parameters:

{Array.} - route parameters extracted from the current $location.path() by applying the current route"

Also

when(path, route) : Method

• path can contain named groups starting with a colon and ending with a star: e.g.:name*. All characters are eagerly stored in $routeParams under the given name when the route matches.

This function will produce required table as list of tuples.

def get_documents_by_user_email(email):
    query = session.query(
       User.email, 
       User.name, 
       Document.name, 
       DocumentsPermissions.readAllowed, 
       DocumentsPermissions.writeAllowed,
    )
    join_query = query.join(Document).join(DocumentsPermissions)

    return join_query.filter(User.email == email).all()

user_docs = get_documents_by_user_email(email)

Instead of using np.argsort you could use np.argpartition - if you only need the indices of the lowest/highest n elements.

That doesn't require to sort the whole array but just the part that you need but note that the "order inside your partition" is undefined, so while it gives the correct indices they might not be correctly ordered:

>>> avgDists = [1, 8, 6, 9, 4]
>>> np.array(avgDists).argpartition(2)[:2]  # indices of lowest 2 items
array([0, 4], dtype=int64)

>>> np.array(avgDists).argpartition(-2)[-2:]  # indices of highest 2 items
array([1, 3], dtype=int64)

Each component has a unique id which can be accessed as this._uid.

<template>
  <div>
    <label :for="id">Label text for {{id}}</label>
    <input :id="id" type="text" />
  </div>
</template>

<script>
export default {
  data () {
    return {
      id: null
    }
  }, 
  mounted () {
    this.id = this._uid
  }
}
</script>

If you want more control over the ids you can for example, generate them inside a parent component.

You're confusing the braces. Do it like this:

target.write("%s \n %s \n %s \n" % (line1, line2, line3))

Or even better, use writelines:

target.writelines([line1, line2, line3])

The easiest way to overwrite a text file is to use a public static field.

this will overwrite the file every time because your only using false the first time through.`

public static boolean appendFile;

Use it to allow only one time through the write sequence for the append field of the write code to be false.

// use your field before processing the write code

appendFile = False;

File fnew=new File("../playlist/"+existingPlaylist.getText()+".txt");
String source = textArea.getText();
System.out.println(source);
FileWriter f2;

try {
     //change this line to read this

    // f2 = new FileWriter(fnew,false);

    // to read this
    f2 = new FileWriter(fnew,appendFile); // important part
    f2.write(source);

    // change field back to true so the rest of the new data will
    // append to the new file.

    appendFile = true;

    f2.close();
 } catch (IOException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
 }           

Sometimes we may not have access to a Jenkins machine to copy a folder directly into another Jenkins instance. So I wrote a menu driven utility which uses Jenkins REST API calls to install plugins and jobs from one Jenkins instance to another.

For plugin migration:

1. GET request: {SOURCE_JENKINS_SERVER}/pluginManager/api/json?depth=1 will get you the list of plugins installed with their version.

2. You can send a POST request with the following parameters to install these plugins.

   final_url=`{DESTINATION_JENKINS_SERVER}/pluginManager/installNecessaryPlugins`
   
   data=`<jenkins><install plugin="{PLUGIN_NAME}@latest"/></jenkins>` (where, latest will fetch the latest version of the plugin_name)
   
   auth=`(destination_jenkins_username, destination_jenkins_password)`
   
   header=`{crumb_field:crumb_value,"Content-Type":"application/xml”}` (where crumb_field=Jenkins-Crumb and get crumb value using API call {DESTINATION_JENKINS_SERVER}/crumbIssuer/api/json
   

For job migration:

1. You can get the list of jobs installed on {SOURCE_JENKINS_URL} using a REST call, {SOURCE_JENKINS_URL}/view/All/api/json
2. Then you can get each job config.xml file from the jobs on {SOURCE_JENKINS_URL} using the job URL {SOURCE_JENKINS_URL}/job/{JOB_NAME}.
3. Use this config.xml file to POST the content of the XML file on {DESTINATION_JENKINS_URL} and that will create a job on {DESTINATION_JENKINS_URL}.

I have created a menu-driven utility in Python which asks the user to start plugin or Jenkins migration and uses Jenkins REST API calls to do it.

You can refer the JenkinsMigration.docx from this URL jenkinsjenkinsmigrationjenkinsrestapi

public class CustomCollection : List<Object>
{
    public Object this[int index]
    {
        // ...
    }
}

You can also use := construct to assign and decide on action in one step. Consider following example:

# Example of setting default server and reporting it's status

server=$1
if [[ ${server:=localhost} =~ [a-z] ]]      # 'localhost' assigned here to $server
then    echo "server is localhost"          # echo is triggered since letters were found in $server
else
        echo "server was set" # numbers were passed
fi

If $1 is not empty, localhost will be assigned to server in the if condition field, trigger match and report match result. In this way you can assign on the fly and trigger appropriate action.

Found the answer here - http://mytechead.wordpress.com/2014/01/30/android-create-a-file-and-write-to-external-storage/

It says,

/**

* Method to check if user has permissions to write on external storage or not

*/

public static boolean canWriteOnExternalStorage() {
   // get the state of your external storage
   String state = Environment.getExternalStorageState();
   if (Environment.MEDIA_MOUNTED.equals(state)) {
    // if storage is mounted return true
      Log.v("sTag", "Yes, can write to external storage.");
      return true;
   }
   return false;
}

and then let’s use this code to actually write to the external storage:

// get the path to sdcard
File sdcard = Environment.getExternalStorageDirectory();
// to this path add a new directory path
File dir = new File(sdcard.getAbsolutePath() + "/your-dir-name/");
// create this directory if not already created
dir.mkdir();
// create the file in which we will write the contents
File file = new File(dir, "My-File-Name.txt");
FileOutputStream os = outStream = new FileOutputStream(file);
String data = "This is the content of my file";
os.write(data.getBytes());
os.close();

And this is it. If now you visit your /sdcard/your-dir-name/ folder you will see a file named - My-File-Name.txt with the content as specified in the code.

PS:- You need the following permission -

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

To filter an array irrespective of the property type (i.e. for all property types), we can create a custom filter pipe

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({ name: "filter" })
export class ManualFilterPipe implements PipeTransform {
  transform(itemList: any, searchKeyword: string) {
    if (!itemList)
      return [];
    if (!searchKeyword)
      return itemList;
    let filteredList = [];
    if (itemList.length > 0) {
      searchKeyword = searchKeyword.toLowerCase();
      itemList.forEach(item => {
        //Object.values(item) => gives the list of all the property values of the 'item' object
        let propValueList = Object.values(item);
        for(let i=0;i<propValueList.length;i++)
        {
          if (propValueList[i]) {
            if (propValueList[i].toString().toLowerCase().indexOf(searchKeyword) > -1)
            {
              filteredList.push(item);
              break;
            }
          }
        }
      });
    }
    return filteredList;
  }
}

//Usage

//<tr *ngFor="let company of companyList | filter: searchKeyword"></tr>

Don't forget to import the pipe in the app module

We might need to customize the logic to filer with dates.

I was importing also some projects from VS2010 to VS 2012. I had the same errors. The errors disappeared when I set back Properties > Config. Properties > General > Platform Toolset to v100 (VS2010). That might not be the correct approach, however.

The trick is to add both max-height: 100%; and max-width: 100%; to .container img. Example CSS:

.container {
  width: 300px;
  border: dashed blue 1px;
}

.container img {
  max-height: 100%;
  max-width: 100%;
}

In this way, you can vary the specified width of .container in whatever way you want (200px or 10% for example), and the image will be no larger than its natural dimensions. (You could specify pixels instead of 100% if you didn't want to rely on the natural size of the image.)

Here's the whole fiddle: http://jsfiddle.net/KatieK/Su28P/1/

I made a **

automatic-network-drive connector

** using a batch file.

Suddenly there was a networkdrive called "Data for Analysation", and yeah with the double quotes it works proper!

looks a little bit different but works:

net use y: "\\share.blabla.com\Folder\Subfolder\Data for Analysation" /USER:domain\username PW /PERSISTENT:YES

Thx for the Hint :)

This approach avoids the warnings while preserving the array-oriented evaluation.

import numpy as np
def isnat(x):
    """ 
    datetime64 analog to isnan.
    doesn't yet exist in numpy - other ways give warnings
    and are likely to change.  
    """
    return x.astype('i8') == np.datetime64('NaT').astype('i8')

Don't use in Browser

In the browser, use document.querySelect('[attribute-name]').

But if you're unit testing and your mocked dom has a flakey querySelector implementation, this will do the trick.

This is @kevinfahy's answer, just trimmed down to be a bit with ES6 fat arrow functions and by converting the HtmlCollection into an array at the cost of readability perhaps.

So it'll only work with an ES6 transpiler. Also, I'm not sure how performant it'll be with a lot of elements.

function getElementsWithAttribute(attribute) {
  return [].slice.call(document.getElementsByTagName('*'))
    .filter(elem => elem.getAttribute(attribute) !== null);
}

And here's a variant that will get an attribute with a specific value

function getElementsWithAttributeValue(attribute, value) {
  return [].slice.call(document.getElementsByTagName('*'))
    .filter(elem => elem.getAttribute(attribute) === value);
}

If you're looking to print this in a page using django templates, then the following might be enough:

{{ birth_date|timesince }}

I had a lot of trouble with this too. Couldn't get it working using the case examples above, but this does the job for me:

Replace(rtrim(ltrim(ISNULL(Flat_no, '') + 
' ' + ISNULL(House_no, '') + 
' ' + ISNULL(Street, '') + 
' ' + ISNULL(Town, '') + 
' ' + ISNULL(City, ''))),'  ',' ')

Replace corrects the double spaces caused by concatenating single spaces with nothing between them. r/ltrim gets rid of any spaces at the ends.

It would be a lot more simple just to do this;

name = input("What's your name? ")
age = int(input("How old are you? "))
print ("Hi,{0} you will be 21 in {1} years.".format(name, 21 - age))`

foreach($array as $item=>$values){
     echo $values->filepath;
    }

If you're changing the layout of an existing ImageView, you should be able to simply get the current LayoutParams, change the width/height, and set it back:

android.view.ViewGroup.LayoutParams layoutParams = myImageView.getLayoutParams();
layoutParams.width = 30;
layoutParams.height = 30;
myImageView.setLayoutParams(layoutParams);

I don't know if that's your goal, but if it is, this is probably the easiest solution.

April 2015 Update

Since this question has been around a while, and some new conventions have come into play, I feel that I should mention the .live method has been depreciated.

In its place, the .on method has now been introduced.

Their documentation is quite useful in explaining how it works;

The .on() method attaches event handlers to the currently selected set of elements in the jQuery object. As of jQuery 1.7, the .on() method provides all functionality required for attaching event handlers. For help in converting from older jQuery event methods, see .bind(), .delegate(), and .live().

So, in order for you to target the 'input focused' event, you can use this in a script. Something like:

$('input').on("focus", function(){
   //do some stuff
});

This is quite robust and even allows you to use the TAB key as well.

Unpacking dictionaries

** unpacks dictionaries.

This

func(a=1, b=2, c=3)

is the same as

args = {'a': 1, 'b': 2, 'c':3}
func(**args)

It's useful if you have to construct parameters:

args = {'name': person.name}
if hasattr(person, "address"):
    args["address"] = person.address
func(**args)  # either expanded to func(name=person.name) or
              #                    func(name=person.name, address=person.address)

Packing parameters of a function

def setstyle(**styles):
    for key, value in styles.iteritems():      # styles is a regular dictionary
        setattr(someobject, key, value)

This lets you use the function like this:

setstyle(color="red", bold=False)

For others who are looking to remove a built-in library, the route is to get into PackageContents -> Java -> libraries.

BUT : IT MAKES NO SENSE TO ELIMINATE LIBRARIES inside the app, they don't take space, don't have any influence on performance, and if you don't know what you are doing, you can harm the program. I did it because Arduino told me about libraries to update, showing then a board I don't have, and when saying ok it wanted to install a lot of new dependencies - I just felt forced to something I don't want, so I deinstalled that board.

Also you can use this code: moment("yourDateHere", "YYYY-MM-DD").fromNow(). This will calculate the difference between today and your provided date.

Every method should be within a class. Your method derivativeQuiz is outside a class.

public class ClassName {

 ///your methods
}

I know this is an oldish question but I found it whilst looking for the same solution. The solution above doesn't appear to work in Laravel 4, you can however use this now:

<a href="{{ URL::previous() }}">Go Back</a>

Hope this helps people who look for this feature in L4

Solution by jay.lee is perfect. In case you want to add item(s) to a multidimensional array, first add a single dimensional array and then replace it afterwards.

$original = (
[0] => Array
    (
        [title] => Speed
        [width] => 14
    )

[1] => Array
    (
        [title] => Date
        [width] => 18
    )

[2] => Array
    (
        [title] => Pineapple
        [width] => 30
     )
)

Adding an item in same format to this array will add all new array indexes as items instead of just item.

$new = array(
    'title' => 'Time',
    'width' => 10
);
array_splice($original,1,0,array('random_string')); // can be more items
$original[1] = $new;  // replaced with actual item

Note: Adding items directly to a multidimensional array with array_splice will add all its indexes as items instead of just that item.

What works for me was org.mockito.ArgumentMatchers.isA

for example:

isA(long[].class)

that works fine.

the implementation difference of each other is:

public static <T> T any(Class<T> type) {
    reportMatcher(new VarArgAware(type, "<any " + type.getCanonicalName() + ">"));
    return Primitives.defaultValue(type);
}

public static <T> T isA(Class<T> type) {
    reportMatcher(new InstanceOf(type));
    return Primitives.defaultValue(type);
}

Use an onclick event, because every click on a checkbox actually changes it.

var inputs = document.getElementsByTagName('input');
for (var i = 0; i < inputs.length; ++i) {
  // ...
}

In Git 1.8.1 you can use the git symbolic-ref command with the "--short" option:

$ git symbolic-ref HEAD
refs/heads/develop
$ git symbolic-ref --short HEAD
develop

You might want to give XStream a shot, it is not complicated. It basically does the heavy lifting.

$(window).on("touchstart", function(ev) {
    var e = ev.originalEvent;
    console.log(e.touches);
});

I know it been asked a long time ago, but I thought a concrete example might help.

cmake mostly cooks a Makefile, one could add rm to the clean PHONY.

For example,

[root@localhost hello]# ls
CMakeCache.txt  CMakeFiles  cmake_install.cmake  CMakeLists.txt  hello  Makefile  test
[root@localhost hello]# vi Makefile
clean:
        $(MAKE) -f CMakeFiles/Makefile2 clean
        rm   -rf   *.o   *~   .depend   .*.cmd   *.mod    *.ko   *.mod.c   .tmp_versions *.symvers *.d *.markers *.order   CMakeFiles  cmake_install.cmake  CMakeCache.txt  Makefile

input width is 10 + 2 times 1 px for border

Often you need to put more into the manifest than what you get with the -e switch, and in that case, the syntax is:

jar -cvfm myJar.jar myManifest.txt myApp.class

Which reads: "create verbose jarFilename manifestFilename", followed by the files you want to include.

Note that the name of the manifest file you supply can be anything, as jar will automatically rename it and put it into the right place within the jar file.

You could use sp_executesql instead of exec. That allows you to specify an output parameter.

declare @out_var varchar(max);
execute sp_executesql 
    N'select @out_var = ''hello world''', 
    N'@out_var varchar(max) OUTPUT', 
    @out_var = @out_var output;
select @out_var;

This prints "hello world".

How to execute Python scripts in Windows?

You could install pylauncher. It is used to launch .py, .pyw, .pyc, .pyo files and supports multiple Python installations:

T\:> blah.py argument

You can run your Python script without specifying .py extension if you have .py, .pyw in PATHEXT environment variable:

T:\> blah argument

It adds support for shebang (#! header line) to select desired Python version on Windows if you have multiple versions installed. You could use *nix-compatible syntax #! /usr/bin/env python.

You can specify version explicitly e.g., to run using the latest installed Python 3 version:

T:\> py -3 blah.py argument

It should also fix your sys.argv issue as a side-effect.
