You could use replicate or sapply:

R> colMeans(replicate(10000, sample(100, size=815, replace=TRUE, prob=NULL))) R> sapply(seq_len(10000), function(...) mean(sample(100, size=815, replace=TRUE, prob=NULL))) 

replicate is a wrapper for the common use of sapply for repeated evaluation of an expression (which will usually involve random number generation).

React-redux 'connect' function accepts two arguments first is mapStateToProps and second is mapDispatchToProps check below ex.

export default connect(mapStateToProps, mapDispatchToProps)(Index); `

If we don't want retrieve state from redux then we set null instead of mapStateToProps.

export default connect(null, mapDispatchToProps)(Index);

I had to do something like this on a version of linux that didn't have the right options compiled into wget. This example is for downloading the memory analysis tool 'guppy'. I'm not sure if it's important or not, but I kept the target file's name the same as the url target name...

Here's what I came up with:

python -c "import requests; r = requests.get('https://pypi.python.org/packages/source/g/guppy/guppy-0.1.10.tar.gz') ; open('guppy-0.1.10.tar.gz' , 'wb').write(r.content)"

That's the one-liner, here's it a little more readable:

import requests
fname = 'guppy-0.1.10.tar.gz'
url = 'https://pypi.python.org/packages/source/g/guppy/' + fname
r = requests.get(url)
open(fname , 'wb').write(r.content)

This worked for downloading a tarball. I was able to extract the package and download it after downloading.

EDIT:

To address a question, here is an implementation with a progress bar printed to STDOUT. There is probably a more portable way to do this without the clint package, but this was tested on my machine and works fine:

#!/usr/bin/env python

from clint.textui import progress
import requests

fname = 'guppy-0.1.10.tar.gz'
url = 'https://pypi.python.org/packages/source/g/guppy/' + fname

r = requests.get(url, stream=True)
with open(fname, 'wb') as f:
    total_length = int(r.headers.get('content-length'))
    for chunk in progress.bar(r.iter_content(chunk_size=1024), expected_size=(total_length/1024) + 1): 
        if chunk:
            f.write(chunk)
            f.flush()

tl;dr

LocalDate.parse(
    "23-Mar-2017" ,
    DateTimeFormatter.ofPattern( "dd-MMM-uuuu" , Locale.US ) 
)

Avoid legacy date-time classes

The Question and other Answers are now outdated, using troublesome old date-time classes that are now legacy, supplanted by the java.time classes.

Using java.time

You seem to be dealing with date-only values. So do not use a date-time class. Instead use LocalDate. The LocalDate class represents a date-only value without time-of-day and without time zone.

Specify a Locale to determine (a) the human language for translation of name of day, name of month, and such, and (b) the cultural norms deciding issues of abbreviation, capitalization, punctuation, separators, and such.

Parse a string.

String input = "23-Mar-2017" ;
DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd-MMM-uuuu" , Locale.US ) ;
LocalDate ld = LocalDate.parse( input , f );

Generate a string.

String output = ld.format( f );

If you were given numbers rather than text for the year, month, and day-of-month, use LocalDate.of.

LocalDate ld = LocalDate.of( 2017 , 3 , 23 );  // ( year , month 1-12 , day-of-month )

See this code run live at IdeOne.com.

input: 23-Mar-2017

ld.toString(): 2017-03-23

output: 23-Mar-2017

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Using a JDBC driver compliant with JDBC 4.2 or later, you may exchange java.time objects directly with your database. No need for strings nor java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

I have used the answer of @Dan Eastwell and it works very well. The code is similar to his code but with some additions.

.granddata {
    position: relative;
    margin-left :0.5%;
    margin-right :0.5%;
}
.granddata:after {
    content : "";
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    background-image: url("/Images/blabla.jpg");
    width: 100%;
    height: 100%;
    opacity: 0.2;
    z-index: -1;
    background-repeat: no-repeat;
    background-position: center;
    background-attachment:fixed;
}

You have writer.close(); in your code. So bash receives EOF on its stdin and exits. Then you get Broken pipe when trying to read from the stdoutof the defunct bash.

There is a shorter alternative to the previous answer. SVG Elements can also be grouped by nesting svg elements:

<svg xmlns="http://www.w3.org/2000/svg"
  xmlns:xlink="http://www.w3.org/1999/xlink">
  <svg x="10">
    <rect x="10" y="10" height="100" width="100" style="stroke:#ff0000;fill: #0000ff"/>
  </svg>
  <svg x="200">
    <rect x="10" y="10" height="100" width="100" style="stroke:#009900;fill: #00cc00"/>
  </svg>
</svg>

The two rectangles are identical (apart from the colors), but the parent svg elements have different x values.

See http://tutorials.jenkov.com/svg/svg-element.html.

You can use it like in the following code where getRequestToForwardPage is the request mapping (URL). You can also use your URL.

function savePopUp(){
    $.blockUI();
    $.ajax({
        url:"GuestHouseProcessor?roomType="+$("#roomType").val(),
        data: $("#popForm").serialize(),
        dataType: "json",
        error: (function() {
            alert("Server Error");
            $.unblockUI();
    }),
    success: function(map) {
        $("#layer1").hide();
        $.unblockUI();
        window.location = "getRequestToForwardPage";
    }
});

This is for the same context of the application.

If you want to use only jquery specific code then following code may help:

 $(location).attr('href',"http://www.google.com");
 $jq(window).attr("location","http://www.google.com");
 $(location).prop('href',"http://www.google.com"); 

This code worked for me:

$(function(){

    $('input:radio').change(function(){
        alert('changed');   
    });          

});

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

I have created a working CodePen example to demonstrate how you might accomplish your goals.

I added ng-click to the <form> and removed the logic from your button:

<form name="addRelation" data-ng-click="save(model)">
...
<input class="btn" type="submit" value="SAVE" />

Here's the updated template:

<section ng-app="app" ng-controller="MainCtrl">
  <form class="well" name="addRelation" data-ng-click="save(model)">
    <label>First Name</label>
    <input type="text" placeholder="First Name" data-ng-model="model.firstName" id="FirstName" name="FirstName" required/><br/>
    <span class="text-error" data-ng-show="addRelation.submitted && addRelation.FirstName.$invalid">First Name is required</span><br/>
    <label>Last Name</label>
    <input type="text" placeholder="Last Name" data-ng-model="model.lastName" id="LastName" name="LastName" required/><br/>
    <span class="text-error" data-ng-show="addRelation.submitted && addRelation.LastName.$invalid">Last Name is required</span><br/>
    <label>Email</label>
    <input type="email" placeholder="Email" data-ng-model="model.email" id="Email" name="Email" required/><br/>
    <span class="text-error" data-ng-show="addRelation.submitted && addRelation.Email.$error.required">Email address is required</span>
    <span class="text-error" data-ng-show="addRelation.submitted && addRelation.Email.$error.email">Email address is not valid</span><br/>
    <input class="btn" type="submit" value="SAVE" />  
  </form>
</section>

and controller code:

app.controller('MainCtrl', function($scope) {  
  $scope.save = function(model) {
    $scope.addRelation.submitted = true;

    if($scope.addRelation.$valid) {
      // submit to db
      console.log(model); 
    } else {
      console.log('Errors in form data');
    }
  };
});

I hope this helps.

I believe you need to map the result before you subscribe to it. You configure it like this:

  updateProfileInformation(user: User) {
    var headers = new Headers();
    headers.append('Content-Type', this.constants.jsonContentType);

    var t = localStorage.getItem("accessToken");
    headers.append("Authorization", "Bearer " + t;
    var body = JSON.stringify(user);

    return this.http.post(this.constants.userUrl + "UpdateUser", body, { headers: headers })
      .map((response: Response) => {
        var result = response.json();
        return result;
      })
      .catch(this.handleError)
      .subscribe(
      status => this.statusMessage = status,
      error => this.errorMessage = error,
      () => this.completeUpdateUser()
      );
  }

A lot of answers have been suggesting clock() and then CLOCKS_PER_SEC from time.h. This is probably a bad idea, because this is what my /bits/time.h file says:

/* ISO/IEC 9899:1990 7.12.1: <time.h>
The macro `CLOCKS_PER_SEC' is the number per second of the value
returned by the `clock' function. */
/* CAE XSH, Issue 4, Version 2: <time.h>
The value of CLOCKS_PER_SEC is required to be 1 million on all
XSI-conformant systems. */
#  define CLOCKS_PER_SEC  1000000l

#  if !defined __STRICT_ANSI__ && !defined __USE_XOPEN2K
/* Even though CLOCKS_PER_SEC has such a strange value CLK_TCK
presents the real value for clock ticks per second for the system.  */
#   include <bits/types.h>
extern long int __sysconf (int);
#   define CLK_TCK ((__clock_t) __sysconf (2))  /* 2 is _SC_CLK_TCK */
#  endif

So CLOCKS_PER_SEC might be defined as 1000000, depending on what options you use to compile, and thus it does not seem like a good solution.

Use btoa("yourstring")

TypeScript is a superset of Javascript, it can use existing Javascript libraries and web APIs

GUID stands for Global Unique Identifier

In Brief: (the clue is in the name)

In Detail: GUIDs are designed to be unique; they are calculated using a random method based on the computers clock and computer itself, if you are creating many GUIDs at the same millisecond on the same machine it is possible they may match but for almost all normal operations they should be considered unique.

There's another important point in constructor chaining: order. Why? Let's say that you have an object being constructed at runtime by a framework that expects it's default constructor. If you want to be able to pass in values while still having the ability to pass in constructor argments when you want, this is extremely useful.

I could for instance have a backing variable that gets set to a default value by my default constructor but has the ability to be overwritten.

public class MyClass
{
  private IDependency _myDependency;
  MyClass(){ _myDependency = new DefaultDependency(); }
  MYClass(IMyDependency dependency) : this() {
    _myDependency = dependency; //now our dependency object replaces the defaultDependency
  }
}

Another method utilizing the dplyr package:

library(dplyr)
df <- mtcars %>%
        filter(mpg > 25)

Without the chain (%>%) operator:

library(dplyr)
df <- filter(mtcars, mpg > 25)

Whenever possible one should avoid culture specific date/time literals.

There are some secure formats to provide a date/time as literal:

All examples for 2016-09-15 17:30:00

ODBC (my favourite, as it is handled as the real type immediately)

• {ts'2016-09-15 17:30:00'} --Time Stamp
• {d'2016-09-15'} --Date only
• {t'17:30:00'} --Time only

ISO8601 (the best for everywhere)

• '2016-09-15T17:30:00' --be aware of the T in the middle!

Unseperated (tiny risk to get misinterpreted as number)

• '20160915' --only for pure date

Good to keep in mind: Invalid dates tend to show up with strange errors

• There is no 31st of June or 30th of February...

One more reason for strange conversion errors: Order of execution!

SQL-Server is well know to do things in an order of execution one might not have expected. Your written statement looks like the conversion is done before some type related action takes place, but the engine decides - why ever - to do the conversion in a later step.

Here is a great article explaining this with examples: Rusano.com: "t-sql-functions-do-no-imply-a-certain-order-of-execution" and here is the related question.

If you want to tweak this for scrolling item within another div,

function isScrolledIntoView (elem, divID) 

{

    var docViewTop = $('#' + divID).scrollTop();


    var docViewBottom = docViewTop + $('#' + divID).height();

    var elemTop = $(elem).offset().top;
    var elemBottom = elemTop + $(elem).height();

    return ((elemBottom <= docViewBottom) && (elemTop >= docViewTop)); 
}

In case you need to the use basic authorisation for your proxy provider, just use the following:

var http = require("http");

var options = {
    host:       FarmerAdapter.PROXY_HOST,
    port:       FarmerAdapter.PROXY_PORT,
    path:       requestedUrl,
    headers:    {
        'Proxy-Authorization':  'Basic ' + new Buffer(FarmerAdapter.PROXY_USER + ':' + FarmerAdapter.PROXY_PASS).toString('base64')
    }
};

var request = http.request(options, function(response) {
    var chunks = [];
    response.on('data', function(chunk) {
        chunks.push(chunk);
    });
    response.on('end', function() {
        console.log('Response', Buffer.concat(chunks).toString());
    });
});

request.on('error', function(error) {
    console.log(error.message);
});

request.end();

No actual difference unless you get the type string. There when you use reflection or GetType() you get {Name = "Boolean" FullName = "System.Boolean"} for both.

it means ONLY one byte will be allocated per character - so if you're using multi-byte charsets, your 1 character won't fit

if you know you have to have at least room enough for 1 character, don't use the BYTE syntax unless you know exactly how much room you'll need to store that byte

when in doubt, use VARCHAR2(1 CHAR)

same thing answered here Difference between BYTE and CHAR in column datatypes

Also, in 12c the max for varchar2 is now 32k, not 4000. If you need more than that, use CLOB

in Oracle, don't use VARCHAR

Guess I'm too late...

Came across the same problem today; here is my solution using FileSystemObject:

Dim objFSO
Const ForReading = 1
Const ForWriting = 2
Dim objTS 'define a TextStream object
Dim strContents As String
Dim fileSpec As String

fileSpec = "C:\Temp\test.txt"
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTS = objFSO.OpenTextFile(fileSpec, ForReading)
strContents = objTS.ReadAll
strContents = Replace(strContents, "XXXXX", "YYYY")
objTS.Close

Set objTS = objFSO.OpenTextFile(fileSpec, ForWriting)
objTS.Write strContents
objTS.Close

How about

SELECT EmailAddress, CustomerName FROM Customers a
WHERE Exists ( SELECT emailAddress FROM customers c WHERE a.customerName != c.customerName AND a.EmailAddress = c.EmailAddress)

I had same issue and my mistake was, I was trying to start tomcat server with incompatible version of JDK and installed Apache tomcat server. In my case I had installed JDK 7 with Apache tomcat 9. For Apache 9 JDK should be >= 8.

For compatibility check this https://tomcat.apache.org/whichversion.html

Solution: On this case, the solution was using the dot, so: rm -rf .* && git clone ssh://[email protected]/home/user/private/repos/project_hub.git .

rm -rf .* && may be omitted if we are absolutely sure that the directory is empty.

The solution would be to install redistributable packages on build server agent. It can be accomplished multiple ways, out of which 3 are described below. Pick one that suits you best.

Use installer with UI

this is the original answer

Right now, in 2017, you can install WebApplication redists with MSBuildTools. Just go to this page that will download MSBuild 2017 Tools and while installation click Web development build tools to get these targets installed as well:

This will lead to installing missing libraries in C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\Microsoft\VisualStudio\v15.0\WebApplications by default

Use command line

disclaimer I haven't tested any of the following proposals

As @PaulHicks and @WaiHaLee suggested in comments, it can also be installed in headless mode (no ui) from CLI, that might actually be preferable way of solving the problem on remove server.

• Solution A - using package manager (choco)

choco install visualstudio2017-workload-webbuildtools

• Solution B - run installer in headless mode

  Notice, this is the same installer that has been proposed to be used in original answer

vs_BuildTools.exe --add Microsoft.VisualStudio.Workload.WebBuildTools --passive

The standard way to create an "empty" object is:

$oVal = new stdClass();

But, with PHP >= 5.4, I personally prefer to use:

$oVal = (object)[];

It's shorter and I personally consider it clearer because stdClass could be misleading to novice programmers (i.e. "Hey, I want an object, not a class!"...).

The same with PHP < 5.4 is:

$oVal = (object) array();

(object)[] is equivalent to new stdClass().

See the PHP manual (here):

stdClass: Created by typecasting to object.

and (here):

If an object is converted to an object, it is not modified. If a value of any other type is converted to an object, a new instance of the stdClass built-in class is created.

However remember that empty($oVal) returns false, as @PaulP said:

Objects with no properties are no longer considered empty.

Regarding your example, if you write:

$oVal = new stdClass();
$oVal->key1->var1 = "something"; // PHP creates  a Warning here
$oVal->key1->var2 = "something else";

PHP creates the following Warning, implicitly creating the property key1 (an object itself)

Warning: Creating default object from empty value

This could be a problem if your configuration (see error reporting level) shows this warning to the browser. This is another entire topic, but a quick and dirty approach could be using the error control operator (@) to ignore the warning:

$oVal = new stdClass();
@$oVal->key1->var1 = "something"; // the warning is ignored thanks to @
$oVal->key1->var2 = "something else";

Try the following configuration:

log4j.rootLogger=TRACE, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.debugLog=org.apache.log4j.FileAppender
log4j.appender.debugLog.File=logs/debug.log
log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout
log4j.appender.debugLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.reportsLog=org.apache.log4j.FileAppender
log4j.appender.reportsLog.File=logs/reports.log
log4j.appender.reportsLog.layout=org.apache.log4j.PatternLayout
log4j.appender.reportsLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.category.debugLogger=TRACE, debugLog
log4j.additivity.debugLogger=false

log4j.category.reportsLogger=DEBUG, reportsLog
log4j.additivity.reportsLogger=false

Then configure the loggers in the Java code accordingly:

static final Logger debugLog = Logger.getLogger("debugLogger");
static final Logger resultLog = Logger.getLogger("reportsLogger");

Do you want output to go to stdout? If not, change the first line of log4j.properties to:

log4j.rootLogger=OFF

and get rid of the stdout lines.

You need to add the Object Authentication as the Parameter to the Session. such as

Session session = Session.getDefaultInstance(props, 
    new javax.mail.Authenticator(){
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(
                "[email protected]", "XXXXX");// Specify the Username and the PassWord
        }
});

now You will not get this kind of Exception....

javax.mail.AuthenticationFailedException: failed to connect, no password specified?

To keep it basic, I used a loop and something like this to get you started (my index are datetimes):

import pandas as pd
import datetime as dt

#populate your dataframe: "df"
#...

df[df.index<(df.index[0]+dt.timedelta(hours=1))] #gives you a slice. you can then take .sum() .mean(), whatever

and then you can run functions on that slice. You can see how adding an iterator to make the start of the window something other than the first value in your dataframes index would then roll the window (you could use a > rule for the start as well for example).

Note, this may be less efficient for SUPER large data or very small increments as your slicing may become more strenuous (works for me well enough for hundreds of thousands of rows of data and several columns though for hourly windows across a few weeks)

The target of the mousemove DOM event is the top-most DOM element under the cursor when the mouse moves:

(function(){
    //Don't fire multiple times in a row for the same element
    var prevTarget=null;
    document.addEventListener('mousemove', function(e) {
        //This will be the top-most DOM element under cursor
        var target=e.target;
        if(target!==prevTarget){
            console.log(target);
            prevTarget=target;
        }
    });
})();

This is similar to @Philip Walton's solution, but doesn't require jQuery or a setInterval.

I prefer to use ***_join in dplyr whenever I need to match data. One possible try for this

left_join(data.frame(name=target),df,by="name")

Note that the input for ***_join require tbls or data.frame

var htmlEnDeCode = (function() {

        charToEntity = {};
        entityToChar = {};
        // add the default set
        addCharacterEntities({
            '&'     :   '&',

            '&quot;'    :   '"',
            '&#39;'     :   "'"
        });
    }

    function addCharacterEntities(newEntities) {
        var charKeys = [],
            entityKeys = [],
            key, echar;
        for (key in newEntities) {
            echar = newEntities[key];
            entityToChar[key] = echar;
            charToEntity[echar] = key;
            charKeys.push(echar);
            entityKeys.push(key);
        }
        charToEntityRegex = new RegExp('(' + charKeys.join('|') + ')', 'g');
        entityToCharRegex = new RegExp('(' + entityKeys.join('|') + '|&#[0-9]{1,5};' + ')', 'g');
    }

    function htmlEncode(value){
        var htmlEncodeReplaceFn = function(match, capture) {
            return charToEntity[capture];
        };

        return (!value) ? value : String(value).replace(charToEntityRegex, htmlEncodeReplaceFn);
    }

    function htmlDecode(value) {
        var htmlDecodeReplaceFn = function(match, capture) {
            return (capture in entityToChar) ? entityToChar[capture] : String.fromCharCode(parseInt(capture.substr(2), 10));
        };

        return (!value) ? value : String(value).replace(entityToCharRegex, htmlDecodeReplaceFn);
    }

    resetCharacterEntities();

    return {
        htmlEncode: htmlEncode,
        htmlDecode: htmlDecode
    };
})();

For Rails 4 - remove the gem name from Gemfile and then run bundle install in your terminal. Also restart the server afterwards.

These answers here didn't help me. So I tried this:

android:windowSoftInputMode="adjustResize"

This worked like a charm, Now the header of my app doesn't disappear. Its smoother.

There's a class of question on SO that sometimes make less than perfect sense, this one is perilously close :-)

Perhaps you could explain your aversion to using one of the two methods you ruled out.

If it's just because you don't want to pepper your code with if statements or exception catching code, one solution is to use a helper function that will take care of it for you, something like:

static String substring_safe (String s, int start, int len) { ... }

which will check lengths beforehand and act accordingly (either return smaller string or pad with spaces).

Then you don't have to worry about it in your code at all, just call:

String s2 = substring_safe (s, 10, 7);

instead of:

String s2 = s.substring (10,7);

This would work in the case that you seem to be worried about (based on your comments to other answers), not breaking the flow of the code when doing lots of string building stuff.

I had to add X-Frame-Options for IE and Content-Security-Policy for other browsers. So i did something like following.

if allowed_domains.present?
  request_host = URI.parse(request.referer)
  _domain = allowed_domains.split(" ").include?(request_host.host) ? "#{request_host.scheme}://#{request_host.host}" : app_host
  response.headers['Content-Security-Policy'] = "frame-ancestors #{_domain}"
  response.headers['X-Frame-Options'] = "ALLOW-FROM #{_domain}"
else
  response.headers.except! 'X-Frame-Options'
end

You test k = M instead of k == M.
Maybe it is what you want to do, in this case, write if (match == 0 && (k = M))

Try withColumn with the function when as follows:

val sqlContext = new SQLContext(sc)
import sqlContext.implicits._ // for `toDF` and $""
import org.apache.spark.sql.functions._ // for `when`

val df = sc.parallelize(Seq((4, "blah", 2), (2, "", 3), (56, "foo", 3), (100, null, 5)))
    .toDF("A", "B", "C")

val newDf = df.withColumn("D", when($"B".isNull or $"B" === "", 0).otherwise(1))

newDf.show() shows

+---+----+---+---+
|  A|   B|  C|  D|
+---+----+---+---+
|  4|blah|  2|  1|
|  2|    |  3|  0|
| 56| foo|  3|  1|
|100|null|  5|  0|
+---+----+---+---+

I added the (100, null, 5) row for testing the isNull case.

I tried this code with Spark 1.6.0 but as commented in the code of when, it works on the versions after 1.4.0.

Usually a back-reference is either $1 or \1 (backslash one) for the first capture group (the first match of a pattern in parentheses), and indeed Sublime supports both syntaxes. So try:

my name used to be \1

or

my name used to be $1

Also note that your original capture pattern:

my name is (\w)+

is incorrect and will only capture the final letter of the name rather than the whole name. You should use the following pattern to capture all of the letters of the name:

my name is (\w+)

No, this is not working. And it's not just for you, in case you spent the last hour trying to find an answer for having your embeded videos open in HD.

Question: Oh, but how do you know this is not working anymore and there is no other alternative to make embeded videos open in a different quality?

Answer: Just went to Google's official documentation regarding Youtube's player parameters and there is not a single parameter that allows you to change its quality.

Also, hd=1 doesn't work either. More info here.

Apparently Youtube analyses the width and height of the user's window (or iframe) and automatically sets the quality based on this.

UPDATE:

As of 10 of April of 2018 it still doesn't work (see my comment on the accepted answer for more details).

What I can see from comments is that it MAY work sometimes, but some others it doesn't. The accepted answer states that "it measures the network speed and the screen and player sizes". So, by that, we can understand that I CANNOT force HD as YouTube will still do whatever it wants in case of low network speed/screen resolution. From my perspective everyone saying it works just have false positives on their hands and on the occasion they tested it worked for some random reason not related to the vq parameter. If it was a valid parameter, Google would document it somewhere, and vq isn't documented anywhere.

This problem was solved by following steps -

1. Go to the local m2 repository and find the directory org/apache/maven/plugins/maven-surefire-plugin.
2. Delete the problematic version.
3. maven update the project, then download it again.

see http://api.jquery.com/prev/

var link = $("#me").parent("div").prev("h3").find("b");
alert(link.text());

see http://jsfiddle.net/gBwLq/

In many cases,

display:inline;

is enough.

But in some cases, you have to add following:

clear:none;

You could do this

            return res.status(201).json({
                statusCode: req.statusCode,
                method: req.method,
                message: 'Question has been added'
            });

Some times If you touch the keyboard accidentally and removed a space.

if [ "$myvar" = "something"]; then
    do something
fi

Will trigger this error message. Note the space before ']' is required.

public static void replaceFileString(String old, String new) throws IOException {
    String fileName = Settings.getValue("fileDirectory");
    FileInputStream fis = new FileInputStream(fileName);
    String content = IOUtils.toString(fis, Charset.defaultCharset());
    content = content.replaceAll(old, new);
    FileOutputStream fos = new FileOutputStream(fileName);
    IOUtils.write(content, new FileOutputStream(fileName), Charset.defaultCharset());
    fis.close();
    fos.close();
}

above is my implementation of Meriton's example that works for me. The fileName is the directory (ie. D:\utilities\settings.txt). I'm not sure what character set should be used, but I ran this code on a Windows XP machine just now and it did the trick without doing that temporary file creation and renaming stuff.

You can use this to get a perfect count, it calculates the mode a particular column

df['name'].value_counts()

I was facing same problem when I installed JRE by Oracle and solved this problem after my research.

I moved the environment path C:\Program Files (x86)\Common Files\Oracle\Java\javapath below H:\Program Files\Java\jdk-13.0.1\bin

Like this:

Path

H:\Program Files\Java\jdk-13.0.1\bin
C:\Program Files (x86)\Common Files\Oracle\Java\javapath

OR

Path

%JAVA_HOME%
%JRE_HOME%

You have 4 columns A,B,C,D

Here is a better way to select the columns you need for the new dataframe:-

df2 = df1[['A','D']]

if you wish to use column numbers instead, use:-

df2 = df1[[0,3]]

I would suggest to disable Redis-server, which prevents auto start while computer restarts and very useful to use docker like tools etc.

Step 1: Stop the redis-server

sudo service redis-server stop

Step 2: Disable the redis-server

sudo systemctl disable redis-server

if you need redis, you can start it as:

sudo service redis-server start

QR codes have three parameters: Datatype, size (number of 'pixels') and error correction level. How much information can be stored there also depends on these parameters. For example the lower the error correction level, the more information that can be stored, but the harder the code is to recognize for readers.

The maximum size and the lowest error correction give the following values:
Numeric only Max. 7,089 characters
Alphanumeric Max. 4,296 characters
Binary/byte Max. 2,953 characters (8-bit bytes)

It's because the tab is a naming container aswell... your update should be update="Search:insTable:display" What you can do aswell is just place your dialog outside the form and still inside the tab then it would be: update="Search:display"

Wow, after few attempts I finally figured out how to deal with my text edits in vbs. The code works perfectly, it gives me the result I was expecting. Maybe it's not the best way to do this, but it does its job. Here's the code:

The following function will delete the input character one by one till the input field is empty using PromiseWhile

driver.clearKeys = function(element, value){
  return element.getAttribute('value').then(function(val) {
    if (val.length > 0) {
      return new Promise(function(resolve, reject) {
        var len;
        len = val.length;
        return promiseWhile(function() { 
          return 0 < len;
        }, function() {
          return new Promise(function(resolve, reject) {
            len--;
            return element.sendKeys(webdriver.Key.BACK_SPACE).then(function()              {

Why are you specifying myFile there?

Git revert reverts the commit(s) that you specify.

git revert HEAD~2

reverts the HEAD~2 commit

git revert HEAD~2 myfile

reverts HEAD~2 AND myFile

I take myFile is a file that you want to revert? In that case use

git checkout HEAD~2 -- myFile

To add some clarification here, when you create your service, the service class uses the default 'wsdlLocation', which was inserted into it when the class was built from the wsdl. So if you have a service class called SomeService, and you create an instance like this:

SomeService someService = new SomeService();

If you look inside SomeService, you will see that the constructor looks like this:

public SomeService() {
        super(__getWsdlLocation(), SOMESERVICE_QNAME);
}

So if you want it to point to another URL, you just use the constructor that takes a URL argument (there are 6 constructors for setting qname and features as well). For example, if you have set up a local TCP/IP monitor that is listening on port 9999, and you want to redirect to that URL:

URL newWsdlLocation = new URL("http://theServerName:9999/somePath");
SomeService someService = new SomeService(newWsdlLocation);

and that will call this constructor inside the service:

public SomeService(URL wsdlLocation) {
    super(wsdlLocation, SOMESERVICE_QNAME);
}

Note that with | char, you can get a warning with your IDE, for exemple I get warning with the last version of IntelliJ, So the best solution it's to use this syntax:

th:text="${'static_content - ' + you_variable}"

For another approach, note that all the standard library functions work with floating point types. You can implement an integer type function like this:

unsigned power(unsigned base, unsigned degree)
{
    unsigned result = 1;
    unsigned term = base;
    while (degree)
    {
        if (degree & 1)
            result *= term;
        term *= term;
        degree = degree >> 1;
    }
    return result;
}

This effectively does repeated multiples, but cuts down on that a bit by using the bit representation. For low integer powers this is quite effective.

The only thing I would suggest is caching the result of values() because each call copies an array. Also, don't create a Random every time. Keep one. Other than that what you're doing is fine. So:

public enum Letter {
  A,
  B,
  C,
  //...

  private static final List<Letter> VALUES =
    Collections.unmodifiableList(Arrays.asList(values()));
  private static final int SIZE = VALUES.size();
  private static final Random RANDOM = new Random();

  public static Letter randomLetter()  {
    return VALUES.get(RANDOM.nextInt(SIZE));
  }
}

<? date_default_timezone_set('Europe/Istanbul'); ?>

For php (or your location).

Joininig @Rudi's and @Pete's answers. I have created an RotateAnimation that keeps buttons functionality also after rotation.

setRotation() method preserves buttons functionality.

Code Sample:

Animation an = new RotateAnimation(0.0f, 180.0f, mainLayout.getWidth()/2, mainLayout.getHeight()/2);

    an.setDuration(1000);              
    an.setRepeatCount(0);                     
    an.setFillAfter(false);              // DO NOT keep rotation after animation
    an.setFillEnabled(true);             // Make smooth ending of Animation
    an.setAnimationListener(new AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {}

        @Override
        public void onAnimationRepeat(Animation animation) {}

        @Override
        public void onAnimationEnd(Animation animation) {
                mainLayout.setRotation(180.0f);      // Make instant rotation when Animation is finished
            }
            }); 

mainLayout.startAnimation(an);

mainLayout is a (LinearLayout) field

If you're using the variable result:

result = result == "true";

This thread has some considerable debate about whether BN should be applied before non-linearity of current layer or to the activations of the previous layer.

Although there is no correct answer, the authors of Batch Normalization say that It should be applied immediately before the non-linearity of the current layer. The reason ( quoted from original paper) -

"We add the BN transform immediately before the nonlinearity, by normalizing x = Wu+b. We could have also normalized the layer inputs u, but since u is likely the output of another nonlinearity, the shape of its distribution is likely to change during training, and constraining its first and second moments would not eliminate the covariate shift. In contrast, Wu + b is more likely to have a symmetric, non-sparse distribution, that is “more Gaussian” (Hyv¨arinen & Oja, 2000); normalizing it is likely to produce activations with a stable distribution."

Something like:

$(".head h3").html("Public offers");

Think about what

if ((state != 10) || (state != 15) || (state != 19) || (state != 22) || (state != 33) || (state != 39) || (state != 47) || (state != 48) || (state != 49) || (state != 51))

means. || means "or." The negation of this is (by DeMorgan's Laws):

state == 10 && state == 15 && state == 19...

In other words, the only way that this could be false if if a state equals 10, 15, and 19 (and the rest of the numbers in your or statement) at the same time, which is impossible.

Thus, this statement will always be true. State 15 will never equal state 10, for example, so it's always true that state will either not equal 10 or not equal 15.

Change || to &&.

Also, in most languages, the following:

if (x) {
  return true;
}
else {
  return false;
}

is not necessary. In this case, the method returns true exactly when x is true and false exactly when x is false. You can just do:

return x;

First check if mingw32-make is installed on your system. Use mingw32-make.exe command in windows terminal or cmd to check, else install the package mingw32-make-bin.

then go to bin directory default ( C:\MinGW\bin) create new file make.bat

@echo off
"%~dp0mingw32-make.exe" %*

add the above content and save it

set the env variable in powershell

$Env:CC="gcc"

then compile the file

make hello

where hello.c is the name of source code

If you don't want to use a separate JS library to create a custom control for that, you could use two confirm dialogs to do the checks:

if (confirm("Are you sure you want to quit?") ) {
    if (confirm("Save your work before leaving?") ) {
        // code here for save then leave (Yes)
    } else {
        //code here for no save but leave (No)
    }
} else {
    //code here for don't leave (Cancel)
}

Thumb Rule: Add a default constructor for each class you used as a mapping class. You missed this and issue arise!
Simply add default constructor and it should work.

None of those answers was not helpful for me.

Finally I have found reason and solution. The reason was a lot of CSS3 filters (filter, -webkit-filter).

Solution

I have added detection of WebView in web page script in order to add class "lowquality" to HTML body. BTW. You can easily track WebView by setting user-agent in WebView settings. Then I created new CSS rule

body.lowquality * { filter: none !important; }

There should be a ReceiveTimeout property in the Socket class.

Sparse checkouts are now in Git 1.7.

Also see the question “Is it possible to do a sparse checkout without checking out the whole repository first?”.

Note that sparse checkouts still require you to download the whole repository, even though some of the files Git downloads won't end up in your working tree.

What about using rawurlencode() ? http://www.php.net/manual/en/function.rawurlencode.php

Here is a function that sanitize even Chinese Chars:

public static function normalizeString ($str = '')
{
    $str = strip_tags($str); 
    $str = preg_replace('/[\r\n\t ]+/', ' ', $str);
    $str = preg_replace('/[\"\*\/\:\<\>\?\'\|]+/', ' ', $str);
    $str = strtolower($str);
    $str = html_entity_decode( $str, ENT_QUOTES, "utf-8" );
    $str = htmlentities($str, ENT_QUOTES, "utf-8");
    $str = preg_replace("/(&)([a-z])([a-z]+;)/i", '$2', $str);
    $str = str_replace(' ', '-', $str);
    $str = rawurlencode($str);
    $str = str_replace('%', '-', $str);
    return $str;
}

Here is the explaination

1. Strip HTML Tags
2. Remove Break/Tabs/Return Carriage
3. Remove Illegal Chars for folder and filename
4. Put the string in lower case
5. Remove foreign accents such as Éàû by convert it into html entities and then remove the code and keep the letter.
6. Replace Spaces with dashes
7. Encode special chars that could pass the previous steps and enter in conflict filename on server. ex. "?????"
8. Replace "%" with dashes to make sure the link of the file will not be rewritten by the browser when querying th file.

OK, some filename will not be releavant but in most case it will work.

ex. Original Name: "???????-??-????????????.jpg"

Output Name: "-E1-83-A1-E1-83-90-E1-83-91-E1-83-94-E1-83-AD-E1-83-93-E1-83-98--E1-83-93-E1-83-90--E1-83-A2-E1-83-98-E1-83-9E-E1-83-9D-E1-83-92-E1-83-A0-E1-83-90-E1-83-A4-E1-83-98-E1-83-A3-E1-83-9A-E1-83-98.jpg"

It's better like that than an 404 error.

Hope that was helpful.

To find the last filled column use the following :

lastColumn = ActiveSheet.Cells(1, Columns.Count).End(xlToLeft).Column

Can this code be simplified in one if test instead two?

nil and '' are different values. If you need to test that s is neither, IMO you should just compare against both, because it makes your intent the most clear.

That and a few alternatives, with their generated bytecode:

if not foo or foo == '' then end
     GETGLOBAL       0 -1    ; foo
     TEST            0 0 0
     JMP             3       ; to 7
     GETGLOBAL       0 -1    ; foo
     EQ              0 0 -2  ; - ""
     JMP             0       ; to 7

if foo == nil or foo == '' then end
    GETGLOBAL       0 -1    ; foo
    EQ              1 0 -2  ; - nil
    JMP             3       ; to 7
    GETGLOBAL       0 -1    ; foo
    EQ              0 0 -3  ; - ""
    JMP             0       ; to 7

if (foo or '') == '' then end
   GETGLOBAL       0 -1    ; foo
   TEST            0 0 1
   JMP             1       ; to 5
   LOADK           0 -2    ; ""
   EQ              0 0 -2  ; - ""
   JMP             0       ; to 7

The second is fastest in Lua 5.1 and 5.2 (on my machine anyway), but difference is tiny. I'd go with the first for clarity's sake.

If you add a new line of text at the end of the existing file which does not already have a newline character at the end, the diff will show the old last line as having been modified, even though conceptually it wasn’t.

This is at least one good reason to add a newline character at the end.

Example

A file contains:

A() {
    // do something
}

Hexdump:

00000000: 4128 2920 7b0a 2020 2020 2f2f 2064 6f20  A() {.    // do 
00000010: 736f 6d65 7468 696e 670a 7d              something.}

You now edit it to

A() {
    // do something
}
// Useful comment

Hexdump:

00000000: 4128 2920 7b0a 2020 2020 2f2f 2064 6f20  A() {.    // do 
00000010: 736f 6d65 7468 696e 670a 7d0a 2f2f 2055  something.}.// U
00000020: 7365 6675 6c20 636f 6d6d 656e 742e 0a    seful comment..

The git diff will show:

-}
\ No newline at end of file
+}
+// Useful comment.

In other words, it shows a larger diff than conceptually occurred. It shows that you deleted the line } and added the line }\n. This is, in fact, what happened, but it’s not what conceptually happened, so it can be confusing.

In ES6 use:

import path from 'path';
const __dirname = path.resolve();

also available when node is called with --experimental-modules

In ajax call mention-

data:MakeModel(),

use the below function to bind data to model

function MakeModel() {

    var MyModel = {};

    MyModel.value = $('#input element id').val() or your value;

    return JSON.stringify(MyModel);
}

Attach [HttpPost] attribute to your controller action

on POST this data will get available

Use a white space to match all descendants of an element:

div.dropdown * {
    color: red;
}

x y matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.

The asterisk * matches any element.

Official Specification: CSS 2.1: Chapter 5.5: Descendant Selectors

To get summary of new/missing files, and which files differ:

diff -arq folder1 folder2

a treats all files as text, r recursively searched subdirectories, q reports 'briefly', only when files differ

I don't know about the older versions but for SSMS 2016 you can go to the Object Explorer and right click on the Databases entry. Then select Attach... in the context menu. Here you can browse to the .mdf file and open it.

Another way to specify the popover content in a reusable way is to create a new data attribute like data-popover-content and use it like this:

HTML:

<!-- Popover #1 -->
<a class="btn btn-primary" data-placement="top" data-popover-content="#a1" data-toggle="popover" data-trigger="focus" href="#" tabindex="0">Popover Example</a>

<!-- Content for Popover #1 -->
<div class="hidden" id="a1">
  <div class="popover-heading">
    This is the heading for #1
  </div>

  <div class="popover-body">
    This is the body for #1
  </div>
</div>

JS:

$(function(){
    $("[data-toggle=popover]").popover({
        html : true,
        content: function() {
          var content = $(this).attr("data-popover-content");
          return $(content).children(".popover-body").html();
        },
        title: function() {
          var title = $(this).attr("data-popover-content");
          return $(title).children(".popover-heading").html();
        }
    });
});

This can be useful when you have a lot of html to place into your popovers.

Here is an example fiddle: http://jsfiddle.net/z824fn6b/

— :: — :: \u2014

When representing the m-dash in a JavaScript text string for output to HTML, note that it will be represented by its unicode value. There are cases when ampersand characters ('&') will not be resolved—notably certain contexts within JSX. In this case, neither — nor — will work. Instead you need to use the Unicode escape sequence: \u2014.

For example, when implementing a render() method to output text from a JavaScript variable:

render() {
   let text='JSX transcoders will preserve the & character—to ' 
            + 'protect from possible script hacking and cross-site hacks.'
   return (
     <div>{text}</div>
   )
}

This will output:

<div>JSX transcoders will preserve the & character&mdash;to protect from possible script hacking and cross-site hacks.</div>

Instead of the &– prefixed representation, you should use \u2014:

let text='JSX transcoders will preserve the & character\u2014to …'

You can try specifying a width for the div, whether it be in pixels, percentages or ems, and at that point the div will remain that width and the text will wrap automatically then within the div.

Why not use a mechanism similar to Apache cron jobs? http://en.wikipedia.org/wiki/Cron

For calendar\scheduling I'd use slightly different values for "bits" to accommodate standard calendar reoccurence events - instead of [day of week (0 - 7), month (1 - 12), day of month (1 - 31), hour (0 - 23), min (0 - 59)]

-- I'd use something like [Year (repeat every N years), month (1 - 12), day of month (1 - 31), week of month (1-5), day of week (0 - 7)]

Hope this helps.

Try this:

while true ; do nc -l -p 1500 -c 'echo -e "HTTP/1.1 200 OK\n\n $(date)"'; done

The -cmakes netcat execute the given command in a shell, so you can use echo. If you don't need echo, use -e. For further information on this, try man nc. Note, that when using echo there is no way for your program (the date-replacement) to get the browser request. So you probably finally want to do something like this:

while true ; do nc -l -p 1500 -e /path/to/yourprogram ; done

Where yourprogram must do the protocol stuff like handling GET, sending HTTP 200 etc.

use overflow:auto property, If overflow is clipped, a scroll-bar should be added to see the rest of the content,and mention the height

DEMO

 .itemconfiguration
    {
        height: 440px;
        width: 215px;
        overflow: auto;
        float: left;
        position: relative;
        margin-left: -5px;
    }

The Background property expects a Brush object, not a string. Change the type of the property to Brush and initialize it thus:

Background = new SolidColorBrush(Colors.Red);

try:

parent.childNodes[1].style.color = "rgb(155, 102, 102)"; 

Or

parent.childNodes[1].style.color = "#"+(155).toString(16)+(102).toString(16)+(102).toString(16);

Install git command line from here. When you install git in windows you will automatically get curl with it. You can check the installed version of curl using curl --version like this.

This is a sample curl request which sends a string in a JSON object and get it encoded.

curl https://api.base62.io/encode \ --request POST \ --header "Content-Type: application/json" \ --data '{ "data": "Hello world!" }'

Set button visibility to GONE (button will be completely "removed" -- the buttons space will be available for another widgets) or INVISIBLE (button will became "transparent" -- its space will not be available for another widgets):

View b = findViewById(R.id.button);
b.setVisibility(View.GONE);

or in xml:

<Button ... android:visibility="gone"/>

Using CASCADE means actually telling Django to delete the referenced record. In the poll app example below: When a 'Question' gets deleted it will also delete the Choices this Question has.

e.g Question: How did you hear about us? (Choices: 1. Friends 2. TV Ad 3. Search Engine 4. Email Promotion)

When you delete this question, it will also delete all these four choices from the table. Note that which direction it flows. You don't have to put on_delete=models.CASCADE in Question Model put it in the Choice.

from django.db import models

class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.dateTimeField('date_published')

class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField(max_legth=200)
    votes = models.IntegerField(default=0)

Try to use setStyle() in onCreate and override onCreateDialog make dialog without title

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);    
    setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme);        
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);        
    return dialog;
}

or just override onCreate() and setStyle fellow the code.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);    
    setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme);        
}

Another option you can always consider is Apache Commons. It provides a lot of options.

import org.apache.commons.lang3.builder.CompareToBuilder;

Ex:

public int compare(Person a, Person b){

   return new CompareToBuilder()
     .append(a.getName(), b.getName())
     .append(a.getAddress(), b.getAddress())
     .toComparison();
}

Another hacked solution, though might be a little cleaner by implementing a Proxy button:

HTML:

<input id="fileInput" type="file">
<md-button class="md-raised" ng-click="upload()">
  <label>AwesomeButtonName</label>
</md-button>

JS:

app.controller('NiceCtrl', function ( $scope) {
  $scope.upload = function () {
    angular.element(document.querySelector('#fileInput')).click();
  };
};

I know this is old post but I struggled today with this problem also and I used template from this page: http://maven.apache.org/plugins/maven-dependency-plugin/usage.html

You can use following simple technique for print log with class name.

private String TAG = MainActivity.class.getSimpleName();

Suppose we have to check coming variable value in method then we can use log like bellow :

private void printVariable(){
Log.e(TAG, "printVariable: ");
}

Importance of this line is that, we can check method name along with class name. To write this type of log.

write :- loge and Enter.

will print on console

E/MainActivity: printVariable:

MVC 4:

    function Cargar_BS(bs) {
        $.getJSON('@Url.Action("GetBienServicio", "MonitoreoAdministracion")',
                        {
                            id: bs
                        },
                        function (d) {
                            $("#txtIdItem").empty().append('<option value="">-Seleccione-</option>');
                            $.each(d, function (idx, item) {
                                jQuery("<option/>").text(item.C_DescBs).attr("value", item.C_CodBs).appendTo("#txtIdItem");
                            })
                            $('#txtIdItem').trigger("chosen:updated");
                        });
    }

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

In my case the built address of my app was set to another computer that was turned off so i turned it on and restart VS and problem solved.

Well, if you're returning Dogs, you'd do:

public IQueryable<Dog> GetDogsWithBreedNames()
{
    var db = new DogDataContext(ConnectString);
    return from d in db.Dogs
           join b in db.Breeds on d.BreedId equals b.BreedId
           select d;
}

If you want the Breed eager-loaded and not lazy-loaded, just use the appropriate DataLoadOptions construct.

If you know the viewport angle of the camera, you can use the height in pixels to determine the angle from the top to bottom of the object. Then, using the distance and arctangent calculate the height:

height = arctan(angle) * distance

To find the viewport angle, point the camera at something which is of known height, and make it exactly fill the screen. For example, point it at a ruler, and make it just far enough away that you can only barely see the ends of the ruler. Measure the distance from the camera, and then your total viewport angle is

viewportAngle = tan(ruler_length / distance)

Then, suppose your camera is 480px tall (cheap webcam), and the view angle is 20°. If you have an object onscreen which is 240px tall, then its angle is 10°. If you know it's 2 feet away, you would say 2 feet * arctan(10°) = ~4.1 inches tall. (I think... it's 2am so this may be a little off)

Try passing it directly to the ng-click function:

<div class="col-lg-1 text-center">
    <span class="glyphicon glyphicon-trash" data="{{event.id}}"
          ng-click="deleteEvent(event.id)"></span>
</div>

Then it should be available in your handler:

$scope.deleteEvent=function(idPassedFromNgClick){
    console.log(idPassedFromNgClick);
}

Here's an example

This might help you

public class FirstActivity extends Activity {

    SharedPreferences sharedPreferences = null;
    Editor editor;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_login);

        sharedPreferences = getSharedPreferences("com.myAppName", MODE_PRIVATE);
    }

    @Override
    protected void onResume() {
        super.onResume();

        if (sharedPreferences.getBoolean("firstRun", true)) {
         //You can perform anything over here. This will call only first time
                 editor = sharedPreferences.edit();
                 editor.putBoolean("firstRun", false)
                 editor.commit();

        }
    }
}

Try renaming the default file. In my case, a recent move to IIS7.5 gave the 405 error. I changed index.aspx to default.aspx and it worked immediately for me.

You can also copy a cell which contains the conditional formatting and then select the range (of destination document -or page-) where you want the conditional format to be applied and select "paste special" > "paste only conditional formatting"

You can use template module to copy if script exists on local machine to remote machine and execute it.

 - name: Copy script from local to remote machine
   hosts: remote_machine
   tasks:
    - name: Copy  script to remote_machine
      template: src=script.sh.2 dest=<remote_machine path>/script.sh mode=755
    - name: Execute script on remote_machine
      script: sh <remote_machine path>/script.sh

Percentage in width works but percentage in height will not work unless you specify a specific height for any parent in the dependent loop...

See this : percentage in height doesn’t work?

For Angular 2+ to get the offset of the current element (this.el.nativeElement is equvalent of $(this) in jquery):

export class MyComponent implements  OnInit {

constructor(private el: ElementRef) {}

    ngOnInit() {
      //This is the important line you can use in your function in the code
      //-------------------------------------------------------------------------- 
        let offset = this.el.nativeElement.getBoundingClientRect().top;
      //--------------------------------------------------------------------------    

        console.log(offset);
    }

}

function valid(id)
    {
        var textVal=document.getElementById(id).value;
        if (!textVal.match("Tryit") 
        {
            alert("Field says Tryit");
            return false;
        } 
        else 
        {
            return true;
        }
     }

Use this for expressing things

I know this is an old issue, but people may still face this.

The following checks if the BundleModule exists in web.config and loaded, and sets EnableOptimizations based on its existance.

This way wether it is available or not, the css/js references will work fine. In other words:

• If BundleModule is available, the bundeling/optimization will be enabled.

• If BundleModule is not available, the bundeling/optimization will be disabled and automatically the full references will be used instead.

Code:

public static void RegisterBundles(BundleCollection bundles)
{
   // bundeling code here
   // ...
   // bundeling code here

   bool bundelingModuleIsAvailable = false;
   try { 
       bundelingModuleIsAvailable = HttpContext.Current.ApplicationInstance.Modules.AllKeys.Contains("BundleModule"); 
   }
   catch { }
   if (!bundelingModuleIsAvailable)
       System.Diagnostics.Debug.WriteLine("WARNING : optimization bundle is not added to Web.config!");

   BundleTable.EnableOptimizations = bundelingModuleIsAvailable && !Debug_CheckIsRunning();
   //Debug_CheckIsRunning is optional, incase you want to disable optimization when debugging yourself
   BundleTable.EnableOptimizations = true;
}

private bool Debug_CheckIsRunning()
{//Check if debug is running
    string moduleName = System.Diagnostics.Process.GetCurrentProcess().MainModule.ModuleName;
    return (moduleName.Contains("iisexpress.exe") || moduleName.Contains(".vshost") || moduleName.Contains("vstest.executionengine") || moduleName.Contains("WebDev.WebServer"));
    }

It's simple enough with the powerful urllib3 library.

Import it like this:

import urllib3

http = urllib3.PoolManager()

And make a request like this:

response = http.request('GET', 'https://example.com')

print(response.data) # Raw data.
print(response.data.decode('utf-8')) # Text.
print(response.status) # Status code.
print(response.headers['Content-Type']) # Content type.

You can add headers too:

    'key1': 'value1',
    'key2': 'value2'
})

More info can be found on the urllib3 documentation.

urllib3 is much safer and easier to use than the builtin urllib.request or http modules and is stable.

Could be short as:

LocalDate.now().format(DateTimeFormatter.ofPattern("dd/MM/yyyy"));

This is the only thing that worked for me:

document.getElementById("chartContainer").innerHTML = ' ';
document.getElementById("chartContainer").innerHTML = '<canvas id="myCanvas"></canvas>';
var ctx = document.getElementById("myCanvas").getContext("2d");

Below code handles upper and lower cases as well and leaves other character as it is.

import java.util.Scanner;

public class CaesarCipher
{
    public static void main(String[] args)
    {
    Scanner in = new Scanner(System.in);
    int length = Integer.parseInt(in.nextLine());
    String str = in.nextLine();
    int k = Integer.parseInt(in.nextLine());

    k = k % 26;

    System.out.println(encrypt(str, length, k));

    in.close();
    }

    private static String encrypt(String str, int length, int shift)
    {
    StringBuilder strBuilder = new StringBuilder();
    char c;
    for (int i = 0; i < length; i++)
    {
        c = str.charAt(i);
        // if c is letter ONLY then shift them, else directly add it
        if (Character.isLetter(c))
        {
        c = (char) (str.charAt(i) + shift);
        // System.out.println(c);

        // checking case or range check is important, just if (c > 'z'
        // || c > 'Z')
        // will not work
        if ((Character.isLowerCase(str.charAt(i)) && c > 'z')
            || (Character.isUpperCase(str.charAt(i)) && c > 'Z'))

            c = (char) (str.charAt(i) - (26 - shift));
        }
        strBuilder.append(c);
    }
    return strBuilder.toString();
    }
}

I know this is a really old question.. and it appears it was answered.. But I got here with the same question but a different reason for the question, and so a slightly different answer worked for me. I have a nice reusable generic datagridview that takes the datasource supplied to it and just displays the columns in their default order. I put aliases and column order and selection at the dataset's tableadapter level in designer. However changing the select query order of columns doesn't seem to impact the columns returned through the dataset. I have found the only way to do this in the designer, is to remove all the columns selected within the tableadapter, adding them back in the order you want them selected.

Just a quick chime in here to hopefully help others... Especially with the newer version (since this is 2 years old)...

Instead of having some static fields defined in JS, you can also use the data-rule-* attributes. You can use built-in rules as well as custom rules.

See http://jqueryvalidation.org/documentation/#link-list-of-built-in-validation-methods for built-in rules.

Example:

<p><label>Email: <input type="text" name="email" id="email" data-rule-email="true" required></label></p>
<p><label>Confirm Email: <input type="text" name="email" id="email_confirm" data-rule-email="true" data-rule-equalTo="#email" required></label></p>

Note the data-rule-* attributes.

My answer is repeating what others have said before, but I thought I'd add an example, using MySQL, only because the previous answers were a little bit cryptic to me.

The general form of the command you need to use to update a single row's column:

UPDATE my_table SET my_column='new value' WHERE something='some value';

And here's an example.

BEFORE

mysql> select aet,port from ae;
+------------+-------+
| aet        | port  |
+------------+-------+
| DCM4CHEE01 | 11112 | 
| CDRECORD   | 10104 | 
+------------+-------+
2 rows in set (0.00 sec)

MAKING THE CHANGE

mysql> update ae set port='10105' where aet='CDRECORD';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

AFTER

mysql> select aet,port from ae;
+------------+-------+
| aet        | port  |
+------------+-------+
| DCM4CHEE01 | 11112 | 
| CDRECORD   | 10105 | 
+------------+-------+
2 rows in set (0.00 sec)

You can use the Youtube Android player API to play the video if Youtube app is installed, otherwise just prompt the user to choose from the available web browsers.

if(YouTubeIntents.canResolvePlayVideoIntent(mContext)){
                    mContext.startActivity(YouTubeIntents.createPlayVideoIntent(mContext, mVideoId));
}else {
    Intent webIntent = new Intent(Intent.ACTION_VIEW, 
           Uri.parse("http://www.youtube.com/watch?v=" + mVideoId));

    mContext.startActivity(webIntent);
}

this will solve, it will accept empty string or exact an email id

"^$|^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$"

another way is using apply, one liner:

cols = ['col1', 'col2', 'col3']
data[cols] = data[cols].apply(pd.to_numeric, errors='coerce', axis=1)

If your dictionary is not nested, you could make a frozenset with the dict's items and use hash():

hash(frozenset(my_dict.items()))

This is much less computationally intensive than generating the JSON string or representation of the dictionary.

UPDATE: Please see the comments below, why this approach might not produce a stable result.

This issue usually appears when one of your variables has no value or when you forget to add "!" to force this variable to store nil until it is set.

In your case the problem is here:

var delegate: AppDelegate

It should be defined as var delegate: AppDelegate! to make it an optional that stores nil and do not unwrap the variable until the value is used.

It is sad that Xcode highlights the whole class as an error instead of highlighting the particular line of code that caused it, so it takes a while to figure it out.

just double tap 'Shift'
and search for 'Line Numbers'
and there you will see a toggle option on or off

RFC 2616, section 14.9.1:

Indicates that all or part of the response message is intended for a single user and MUST NOT be cached by a shared cache...A private (non-shared) cache MAY cache the response.

Browsers could use this information. Of course, the current "user" may mean many things: OS user, a browser user (e.g. Chrome's profiles), etc. It's not specified.

For me, a more concrete example of Cache-Control: private is that proxy servers (which typically have many users) won't cache it. It is meant for the end user, and no one else.

FYI, the RFC makes clear that this does not provide security. It is about showing the correct content, not securing content.

This usage of the word private only controls where the response may be cached, and cannot ensure the privacy of the message content.

After making above improvement such as checking if mysql service is running or not, you just need to give a small password while creating connection, it is ' ' or 1 time press on space-bar in case of GUI or workbench. After which you just need to validate your machine with server (validated HOST). For that purpose click on 'New Server Instance' and it will configure server/HOST on your behalf itself.

I have done this successfully just a few couple of minutes ago. My workbench software is able to show all pre-installed databases etc now.

hope it will work for you as well.

Thanks!!!

For an unknow reason, the accepted answer partially works when I send email to my gmail address. I have the attachement but not the text of the email.

If you want both attachment and text try this based on the accepted answer :

    Properties props = new java.util.Properties();
    props.put("mail.smtp.host", "yourHost");
    props.put("mail.smtp.port", "yourHostPort");
    props.put("mail.smtp.auth", "true");             
    props.put("mail.smtp.starttls.enable", "true");


    // Session session = Session.getDefaultInstance(props, null);
    Session session = Session.getInstance(props,
              new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication("user", "password");
                }
              });


    Message msg = new MimeMessage(session);
    try {
        msg.setFrom(new InternetAddress(mailFrom));
        msg.setRecipient(Message.RecipientType.TO, new InternetAddress(mailTo));
        msg.setSubject("your subject");

        Multipart multipart = new MimeMultipart();

        MimeBodyPart textBodyPart = new MimeBodyPart();
        textBodyPart.setText("your text");

        MimeBodyPart attachmentBodyPart= new MimeBodyPart();
        DataSource source = new FileDataSource(attachementPath); // ex : "C:\\test.pdf"
        attachmentBodyPart.setDataHandler(new DataHandler(source));
        attachmentBodyPart.setFileName(fileName); // ex : "test.pdf"

        multipart.addBodyPart(textBodyPart);  // add the text part
        multipart.addBodyPart(attachmentBodyPart); // add the attachement part

        msg.setContent(multipart);


        Transport.send(msg);
    } catch (MessagingException e) {
        LOGGER.log(Level.SEVERE,"Error while sending email",e);
    }

Update :

If you want to send a mail as an html content formated you have to do

    MimeBodyPart textBodyPart = new MimeBodyPart();
    textBodyPart.setContent(content, "text/html");

So basically setText is for raw text and will be well display on every server email including gmail, setContent is more for an html template and if you content is formatted as html it will maybe also works in gmail

The main issue with your example that you can't implicitly convert Task<T> return types to the base T type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.

Try this instead:

public List<int> TestGetMethod()  
{  
    return GetIdList().Result;  
}

REVERSIBLE Method to Discard All Changes:

I found this question after after making a merge and forgetting to checkout develop immediately afterwards. You guessed it: I started modifying a few files directly on master. D'Oh! As my situation is hardly unique (we've all done it, haven't we ;->), I'll offer a reversible way I used to discard all changes to get master looking like develop again.

After doing a git diff to see what files were modified and assess the scope of my error, I executed:

git stash
git stash clear

After first stashing all the changes, they were next cleared. All the changes made to the files in error to master were gone and parity restored.

Let's say I now wanted to restore those changes. I can do this. First step is to find the hash of the stash I just cleared/dropped:

git fsck --no-reflog | awk '/dangling commit/ {print $3}'

After learning the hash, I successfully restored the uncommitted changes with:

git stash apply hash-of-cleared-stash

I didn't really want to restore those changes, just wanted to validate I could get them back, so I cleared them again.

Another option is to apply the stash to a different branch, rather than wipe the changes. So in terms of clearing changes made from working on the wrong branch, stash gives you a lot of flexibility to recover from your boo-boo.

Anyhoo, if you want a reversible means of clearing changes to a branch, the foregoing is a less dangerous way in this use-case.

You can declare like one of the below options:

char data[] = "Testing String";

or

const char* data = "Testing String";

or

char* data = (char*) "Testing String";

My solution needs the following import.

import java.io.File;

The following method should return the desired output string:

private static String getFilenameWithoutExtension(File file) throws IOException {
    String filename = file.getCanonicalPath();
    String filenameWithoutExtension;
    if (filename.contains("."))
        filenameWithoutExtension = filename.substring(filename.lastIndexOf(System.getProperty("file.separator"))+1, filename.lastIndexOf('.'));
    else
        filenameWithoutExtension = filename.substring(filename.lastIndexOf(System.getProperty("file.separator"))+1);

    return filenameWithoutExtension;
}

var result = priceLog.GroupBy(s => s.LogDateTime.ToString("MMM yyyy")).Select(grp => new PriceLog() { LogDateTime = Convert.ToDateTime(grp.Key), Price = (int)grp.Average(p => p.Price) }).ToList();

I have converted it to int because my Price field was int and Average method return double .I hope this will help

Solution that work for me :

var editorInstance = CKEDITOR.instances[this.editorId];

            editorInstance.on('focus', function(e) {

                console.log("tadaaa");

            });

states = "Alaska Alabama Arkansas American Samoa Arizona California Colorado"
states_list = states.split (' ')

I would do something like this

DEMO in JsBin: http://jsbin.com/ofiqur/1/

  <a href="#" id="showmenu">Click Here</a>
  <div class="menu">
    <ul>
      <li><a href="#">Button 1</a></li>
      <li><a href="#">Button 2</a></li>
      <li><a href="#">Button 3</a></li>
    </ul>
  </div>

and in jQuery as simple as

var min = "-100px", // remember to set in css the same value
    max = "0px";

$(function() {
  $("#showmenu").click(function() {

    if($(".menu").css("marginLeft") == min) // is it left?
      $(".menu").animate({ marginLeft: max }); // move right
    else
      $(".menu").animate({ marginLeft: min }); // move left

  });
});

If the array is plain and the order is matter so this two lines may help

//Assume
var a = ['a','b', 'c']; var b = ['a','e', 'c'];  

if(a.length !== b.length) return false;
return !a.reduce(
  function(prev,next,idx, arr){ return prev || next != b[idx] },false
); 

Reduce walks through one of array and returns 'false' if at least one element of 'a' is nor equial to element of 'b' Just wrap this into function

I put above-mentioned methods together using ax instead of plt

import numpy as np
import matplotlib.pyplot as plt

x = range(100)
y = x

fig, ax = plt.subplots(1, 1, figsize=(7.2, 7.2))
ax.plot(x, y);

# method 1
print(ax.get_xlim())
print(ax.get_xlim())
# method 2
print(ax.axis())

A turkish one. If someone is still interested.

 $('input[type="text"]').keyup(function() {
    $(this).val($(this).val().replace(/^([a-zA-Z\s\ö\ç\s\i\i\g\ü\Ö\Ç\S\I\G\Ü])|\s+([a-zA-Z\s\ö\ç\s\i\i\g\ü\Ö\Ç\S\I\G\Ü])/g, function ($1) {
        if ($1 == "i")
            return "I";
        else if ($1 == " i")
            return " I";
        return $1.toUpperCase();
    }));
});

You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015 > 01/02/2016 because 09 > 01. You need to either put your date in a comparable string format or compare DateTime objects which are comparable.

<?php
 $date_now = date("Y-m-d"); // this format is string comparable

if ($date_now > '2016-01-02') {
    echo 'greater than';
}else{
    echo 'Less than';
}

Demo

Or

<?php
 $date_now = new DateTime();
 $date2    = new DateTime("01/02/2016");

if ($date_now > $date2) {
    echo 'greater than';
}else{
    echo 'Less than';
}

I have debian 9 and to fix this i used the new library as follows:

If you don't care about IE =6, you could use pure CSS ...

.forum:hover { background-color: #380606; }

.forum { color: white; }_x000D_
.forum:hover { background-color: #380606 !important; }_x000D_
/* we use !important here to override specificity. see http://stackoverflow.com/q/5805040/ */_x000D_
_x000D_
#blue { background-color: blue; }

<meta charset=utf-8>_x000D_
_x000D_
<p class="forum" style="background-color:red;">Red</p>_x000D_
<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>

With jQuery, usually it is better to create a specific class for this style:

.forum_hover { background-color: #380606; }

and then apply the class on mouseover, and remove it on mouseout.

$('.forum').hover(function(){$(this).toggleClass('forum_hover');});

$(document).ready(function(){_x000D_
  $('.forum').hover(function(){$(this).toggleClass('forum_hover');});_x000D_
});

.forum_hover { background-color: #380606 !important; }_x000D_
_x000D_
.forum { color: white; }_x000D_

<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>

If you must not modify the class, you could save the original background color in .data():

  $('.forum').data('bgcolor', '#380606').hover(function(){
    var $this = $(this);
    var newBgc = $this.data('bgcolor');
    $this.data('bgcolor', $this.css('background-color')).css('background-color', newBgc);
  });

$(document).ready(function(){_x000D_
  $('.forum').data('bgcolor', '#380606').hover(function(){_x000D_
    var $this = $(this);_x000D_
    var newBgc = $this.data('bgcolor');_x000D_
    $this.data('bgcolor', $this.css('background-color')).css('background-color', newBgc);_x000D_
  });_x000D_
});

.forum { color: white; }_x000D_
#blue { background-color: blue; }

  $('.forum').hover(

      $this.data('bgcolor', $this.css('background-color')).css('background-color', '#380606');

Also, starting with .NET Core 3.0 (and .NET Standard 2.1) (C# 8) you can use Index type to keep array's indexes from end:

var lastElementIndexInAnyArraySize = ^1;
var lastElement = array[lastElementIndexInAnyArraySize];

You can use this index to get last array value in any lenght of array. For example:

var firstArray = new[] {0, 1, 1, 2, 2};
var secondArray = new[] {3, 3, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5};
var index = ^1;
var firstArrayLastValue = firstArray[index]; // 2
var secondArrayLastValue = secondArray[index]; // 5

If you are the one who created the singleton and who uses it, dont make it as singleton (it doesn't have sense because you can control the singularity of the object without making it singleton) but it makes sense when you a developer of a library and you want to supply only one object to your users (in this case you are the who created the singleton, but you aren't the user).

Singletons are objects so use them as objects, many people accesses to singletons directly through calling the method which returns it, but this is harmful because you are making your code knows that object is singleton, I prefer to use singletons as objects, I pass them through the constructor and I use them as ordinary objects, by that way, your code doesn't know if these objects are singletons or not and that makes the dependencies more clear and it helps a little for refactoring ...

Transform the sets into arrays, flatten them and finally the constructor will uniqify.

const union = (...sets) => new Set(sets.map(s => [...s]).flat());

Run a packet sniffer (e.g., Wireshark) also on the peer to see whether it's the peer who's sending the RST or someone in the middle.

Adding my piece of experience. I spent hours trying to find why I had CORS error.

It happens that I've renamed my cloud function (the very first I was trying after a big upgrade).

So when my firebase app was calling the cloud function with an incorrect name, it should have thrown a 404 error, not a CORS error.

Fixing the cloud function name in my firebase app fixed the issue.

I've filled a bug report about this here https://firebase.google.com/support/troubleshooter/report/bugs

This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.

This can happen if the other side crashes and then comes back up or if it calls close() on the socket while there is data from you in transit, and is an indication to you that some of the data that you previously sent may not have been received.

It is up to you whether that is an error; if the information you were sending was only for the benefit of the remote client then it may not matter that any final data may have been lost. However you should close the socket and free up any other resources associated with the connection.

There are several options for removing one or more columns with dplyr::select() and some helper functions. The helper functions can be useful because some do not require naming all the specific columns to be dropped. Note that to drop columns using select() you need to use a leading - to negate the column names.

Using the dplyr::starwars sample data for some variety in column names:

library(dplyr)

starwars %>% 
  select(-height) %>%                  # a specific column name
  select(-one_of('mass', 'films')) %>% # any columns named in one_of()
  select(-(name:hair_color)) %>%       # the range of columns from 'name' to 'hair_color'
  select(-contains('color')) %>%       # any column name that contains 'color'
  select(-starts_with('bi')) %>%       # any column name that starts with 'bi'
  select(-ends_with('er')) %>%         # any column name that ends with 'er'
  select(-matches('^v.+s$')) %>%       # any column name matching the regex pattern
  select_if(~!is.list(.)) %>%          # not by column name but by data type
  head(2)

# A tibble: 2 x 2
homeworld species
  <chr>     <chr>  
1 Tatooine  Human  
2 Tatooine  Droid 

You can also drop by column number:

starwars %>% 
  select(-2, -(4:10)) # column 2 and columns 4 through 10

CSS is used for applying styling i.e. the visual aspects of an interface.

That clicking an anchor element causes an action to be performed is a behavioural aspect of an interface, not a stylistic aspect.

You cannot achieve what you want using only CSS.

JavaScript is used for applying behaviours to an interface. You can use JavaScript to modify the behaviour of a link.

Try closing and reopening the file, then press Ctrl+F11.

Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.

Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.

Here's my angle on it, based on Hernaldo's, if you need to find files with names of a certain pattern, such as XML files that somewhere in their name contain a particular string:

// call this like so: GetXMLFiles("Platypus", "C:\\");
public static List<string> GetXMLFiles(string fileType, string dir)
{
    string dirName = dir; 
    var fileNames = new List<String>();
    try
    {
        foreach (string f in Directory.GetFiles(dirName))
        {
            if ((f.Contains(fileType)) && (f.Contains(".XML")))
            {
                fileNames.Add(f);
            }
        }
        foreach (string d in Directory.GetDirectories(dirName))
        {
            GetXMLFiles(fileType, d);
        }

It seems that you will get the same result for both, but hostname contains clear host name without brackets or port number.

They are slightly different - the ETag does not have any information that the client can use to determine whether or not to make a request for that file again in the future. If ETag is all it has, it will always have to make a request. However, when the server reads the ETag from the client request, the server can then determine whether to send the file (HTTP 200) or tell the client to just use their local copy (HTTP 304). An ETag is basically just a checksum for a file that semantically changes when the content of the file changes.

The Expires header is used by the client (and proxies/caches) to determine whether or not it even needs to make a request to the server at all. The closer you are to the Expires date, the more likely it is the client (or proxy) will make an HTTP request for that file from the server.

So really what you want to do is use BOTH headers - set the Expires header to a reasonable value based on how often the content changes. Then configure ETags to be sent so that when clients DO send a request to the server, it can more easily determine whether or not to send the file back.

One last note about ETag - if you are using a load-balanced server setup with multiple machines running Apache you will probably want to turn off ETag generation. This is because inodes are used as part of the ETag hash algorithm which will be different between the servers. You can configure Apache to not use inodes as part of the calculation but then you'd want to make sure the timestamps on the files are exactly the same, to ensure the same ETag gets generated for all servers.

Just to clarify ... You should always use httpS

But you can bypass it adding the exception:

umh.. like that?

$newstring = substr($dynamicstring, -7);

The stack pointer stores the address of the most recent entry that was pushed onto the stack.

To push a value onto the stack, the stack pointer is incremented to point to the next physical memory address, and the new value is copied to that address in memory.

To pop a value from the stack, the value is copied from the address of the stack pointer, and the stack pointer is decremented, pointing it to the next available item in the stack.

The most typical use of a hardware stack is to store the return address of a subroutine call. When the subroutine is finished executing, the return address is popped off the top of the stack and placed in the Program Counter register, causing the processor to resume execution at the next instruction following the call to the subroutine.

Sorry for late reply.But this would work properly.

daytext=(textview)findviewById(R.id.day);

Calender c=Calender.getInstance();
SimpleDateFormat sd=new SimpleDateFormat("EEEE");
String dayofweek=sd.format(c.getTime());


daytext.setText(dayofweek);

You can try the following solution:

curl -v -X POST -d @payload.xml https://<API Path> -k -H "Content-Type: application/xml;charset=utf-8"

Use the STR function:

SELECT STR(field_name) FROM table_name

Arguments

float_expression

Is an expression of approximate numeric (float) data type with a decimal point.

length

Is the total length. This includes decimal point, sign, digits, and spaces. The default is 10.

decimal

Is the number of places to the right of the decimal point. decimal must be less than or equal to 16. If decimal is more than 16 then the result is truncated to sixteen places to the right of the decimal point.

You can set up a default way to shorten the command line and use it as a template for further configurations by changing the default JUnit Run/Debug Configuration template. Then all new Run/Debug configuration you create in project will use the same option.

Here is the related blog post about configurable command line shortener option.

Just check for it before you pass to your function. So you would pass:

thing.foo ? thing.foo.bar : undefined

You may also try the following code with exception handling. Here you have a method removeLast(String s, int n) (it is actually an modified version of masud.m's answer). You have to provide the String s and how many char you want to remove from the last to this removeLast(String s, int n) function. If the number of chars have to remove from the last is greater than the given String length then it throws a StringIndexOutOfBoundException with a custom message -

public String removeLast(String s, int n) throws StringIndexOutOfBoundsException{

        int strLength = s.length();

        if(n>strLength){
            throw new StringIndexOutOfBoundsException("Number of character to remove from end is greater than the length of the string");
        }

        else if(null!=s && !s.isEmpty()){

            s = s.substring(0, s.length()-n);
        }

        return s;

    }

Here is what I have implemented.

function summaryMode($text, $limit, $link) {
    if (str_word_count($text, 0) > $limit) {
        $numwords = str_word_count($text, 2);
        $pos = array_keys($numwords);
        $text = substr($text, 0, $pos[$limit]).'... <a href="'.$link.'">Read More</a>';
    }
    return $text;
}

As you can see it is based off karim79's answer, all that needed changing was that the if statement also needed to check against words not characters.

I also added a link to main function for convenience. So far it hsa worked flawlessly. Thanks to the original solution provider.

The EXCEL and OLED DB connection managers use the parameter names 0 and 1.

I was using a oledb connection and wasted couple of hours trying to figure out the reason why the query was not working or taking the parameters. the above explanation helped a lot Thanks a lot.

Basically the problem is with file path. The forward slash in the beginning of the url makes it look for the file at the root. Removing that, it will be a path relative to this css file - like this: background-image: url(img/debut_dark.png);

If you are using Atom, copying the project path of image sometimes includes forward slash in the copied path so be careful.

In JQuery you can call

$("form:first").trigger("submit")

Don't know if that is much better. I think form.submit(); is pretty universal.

Below code will hide your text with fixed width you decide. but not quite right for responsive designs.

.CropLongTexts {
  width: 170px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

Update

I have noticed in (mobile) device(s) that the text (mixed) with each other due to (fixed width)... so i have edited the code above to become hidden responsively as follow:

.CropLongTexts {
  max-width: 170px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

The (max-width) ensure the text will be hidden responsively whatever the (screen size) and will not mixed with each other.

Just leave out the "dot-slash" ./:

D:\Gesture Recognition\Gesture Recognition\Debug>"Gesture Recognition.exe"

Though, if you wanted to, you could use .\ and it would work.

D:\Gesture Recognition\Gesture Recognition\Debug>.\"Gesture Recognition.exe"

As per below @rpgmaker comment i added this answer

yes you can do using ResolveInfo class

check your file is supported with already installed apps or not

using below code:

private boolean isSupportedFile(File file) throws PackageManager.NameNotFoundException {
    PackageManager pm = mContext.getPackageManager();
    java.io.File mFile = new java.io.File(file.getFileName());
    Uri data = Uri.fromFile(mFile);
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(data, file.getMimeType());
    List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);

    if (resolveInfos != null && resolveInfos.size() > 0) {
        Drawable icon = mContext.getPackageManager().getApplicationIcon(resolveInfos.get(0).activityInfo.packageName);
        Glide.with(mContext).load("").placeholder(icon).into(binding.fileAvatar);
        return true;
    } else {
        Glide.with(mContext).load("").placeholder(R.drawable.avatar_defaultworkspace).into(binding.fileAvatar);
        return false;
    }
}

You could also put non-breaking spaces (&nbsp;) in lieu of the spaces so that they're forced to stay together.

How do I wrap this line of text
- asked by Peter 2 days ago

Parent container has to have this:

position: relative;

Button itself has to have this:

position: relative;
bottom: 20px;
right: 20px;

or whatever you like

You need to decide exactly what you want to do - and preferably explain it a bit more clearly.

Option 1: File

If you know which file you want the output of the executed command to go to, then:

1. Ensure that the parent and child agree on the name (parent decides name before forking).
2. Parent forks - you have two processes.
3. Child reorganizes things so that file descriptor 1 (standard output) goes to the file.
4. Usually, you can leave standard error alone; you might redirect standard input from /dev/null.
5. Child then execs relevant command; said command runs and any standard output goes to the file (this is the basic shell I/O redirection).
6. Executed process then terminates.
7. Meanwhile, the parent process can adopt one of two main strategies:
   • Open the file for reading, and keep reading until it reaches an EOF. It then needs to double check whether the child died (so there won't be any more data to read), or hang around waiting for more input from the child.
   • Wait for the child to die and then open the file for reading.
   • The advantage of the first is that the parent can do some of its work while the child is also running; the advantage of the second is that you don't have to diddle with the I/O system (repeatedly reading past EOF).

Option 2: Pipe

If you want the parent to read the output from the child, arrange for the child to pipe its output back to the parent.

1. Use popen() to do this the easy way. It will run the process and send the output to your parent process. Note that the parent must be active while the child is generating the output since pipes have a small buffer size (often 4-5 KB) and if the child generates more data than that while the parent is not reading, the child will block until the parent reads. If the parent is waiting for the child to die, you have a deadlock.
2. Use pipe() etc to do this the hard way. Parent calls pipe(), then forks. The child sorts out the plumbing so that the write end of the pipe is its standard output, and ensures that all other file descriptors relating to the pipe are closed. This might well use the dup2() system call. It then executes the required process, which sends its standard output down the pipe.
3. Meanwhile, the parent also closes the unwanted ends of the pipe, and then starts reading. When it gets EOF on the pipe, it knows the child has finished and closed the pipe; it can close its end of the pipe too.

Best practice

According to the documentation since Symfony 2.1 simply use this shortcut :

$user = $this->getUser();

The above is still working on Symfony 3.2 and is a shortcut for this :

$user = $this->get('security.token_storage')->getToken()->getUser();

The security.token_storage service was introduced in Symfony 2.6. Prior to Symfony 2.6, you had to use the getToken() method of the security.context service.

Example : And if you want directly the username :

$username = $this->getUser()->getUsername();

If wrong user class type

The user will be an object and the class of that object will depend on your user provider.

You should be using a class to achieve what you want:

css:

#topbar { width: 100%; height: 40px; background-color: #000; }
#topbar.hide { height: 10px; }

javascript:

  $(document).ready(function(){
    $("#topbar").click(function(){
      if($(this).hasClass('hide')) {
        $(this).animate({height:40},200).removeClass('hide');
      } else { 
        $(this).animate({height:10},200).addClass('hide');
      }
    });
  });

For those who use Linux and the other packages haven't worked on MP3 files, audioplayer worked fine for me:

https://pypi.org/project/audioplayer/

from audioplayer import AudioPlayer<br>
AudioPlayer("path/to/somemusic.mp3").play(block=True)

Here is one more answer from @Marged in comments

1. Create a folder with the name you want

2. Run the command below from the folder you created

   git clone <path to your online repo> .
   

You can pass it as a List<DateTime>

public void somefunction(List<DateTime> dates)
{
}

However, it's better to use the most generic (as in general, base) interface possible, so I would use

public void somefunction(IEnumerable<DateTime> dates)
{
}

or

public void somefunction(ICollection<DateTime> dates)
{
}

You might also want to call .AsReadOnly() before passing the list to the method if you don't want the method to modify the list - add or remove elements.

If you're using anaconda:

conda list

will do it! See: https://conda.io/docs/_downloads/conda-cheatsheet.pdf

This can happen if you don't attach your dataset.

Creating a new list and populating valid values in new list worked for me.

Code throwing error -

List<String> list = new ArrayList<>();
   for (String s: list) {
     if(s is null or blank) {
        list.remove(s);
     }
   }
desiredObject.setValue(list);

After fix -

 List<String> list = new ArrayList<>();
 List<String> newList= new ArrayList<>();
 for (String s: list) {
   if(s is null or blank) {
      continue;
   }
   newList.add(s);
 }
 desiredObject.setValue(newList);

The part about not being able to use the Back button is a common misinterpretation. window.location.replace(URL) throws out the top ONE entry from the page history list, by overwriting it with the new entry, so the user can't easily go Back to that ONE particular webpage. The function does NOT wipe out the entire page history list, nor does it make the Back button completely non-functional.

(NO function nor combination of parameters that I know of can change or overwrite history list entries that you don't own absolutely for certain - browsers generally impelement this security limitation by simply not even defining any operation that might at all affect any entry other than the top one in the page history list. I shudder to think what sorts of dastardly things malware might do if such a function existed.)

If you really want to make the Back button non-functional (probably not "user friendly": think again if that's really what you want to do), "open" a brand new window. (You can "open" a popup that doesn't even have a "Back" button too ...but popups aren't very popular these days:-) If you want to keep your page showing no matter what the user does (again the "user friendliness" is questionable), set up a window.onunload handler that just reloads your page all over again clear from the very beginning every time.

Just use the build-in feature of Angular CLI

ng update

to update to the latest version.

or this, I did not implement the array comparison so you will also have some fun :)

public bool CompareTables(DataTable a, DataTable b)
{
    if(a.Rows.Count != b.Rows.Count)
    {
        // different size means different tables
        return false;
    }

    for(int rowIndex=0; rowIndex<a.Rows.Count; ++rowIndex)
    {
        if(!arraysHaveSameContent(a.Rows[rowIndex].ItemArray, b.Rows[rowIndex].ItemArray,))
        {
            return false;
        }
    }

    // Tables have same data
    return true;
}

private bool arraysHaveSameContent(object[] a, object[] b)
{
    // Here your super cool method to compare the two arrays with LINQ,
    // or if you are a loser do it with a for loop :D
}

According to: Java Revisited

1. Resources included by include directive are loaded during jsp translation time, while resources included by include action are loaded during request time.

2. Any change on included resources will not be visible in case of include directive until jsp file compiles again. While in case of include action, any change in included resource will be visible in the next request.

3. Include directive is static import, while include action is dynamic import.

4. Include directive uses file attribute to specify resources to be included while include action uses page attribute for the same purpose.

The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.

sudo apt-get install ruby-all-dev

worked for me.

In Python 3, use

print('h', end='')

to suppress the endline terminator, and

print('a', 'b', 'c', sep='')

to suppress the whitespace separator between items. See the documentation for print

SetOnClickListener (Android.View.view.OnClickListener) in View cannot be applied to (com.helloandroidstudio.MainActivity)

This means in other words (due to your current scenario) that your MainActivity need to implement OnClickListener:

public class Main extends ActionBarActivity implements View.OnClickListener {
   // do your stuff
}

This:

buttonname.setOnClickListener(this);

means that you want to assign listener for your Button "on this instance" -> this instance represents OnClickListener and for this reason your class have to implement that interface.

It's similar with anonymous listener class (that you can also use):

buttonname.setOnClickListener(new View.OnClickListener() {

   @Override
   public void onClick(View view) {

   }
});

I don't think maven supports this. If you're on Unix, and don't want to leave your current directory, you could use a small shell script, a shell function, or just a sub-shell:

user@host ~/project$ (cd ~/some/location; mvn install)
[ ... mvn build ... ]
user@host ~/project$

As a bash function (which you could add to your ~/.bashrc):

function mvn-there() {
  DIR="$1"
  shift
  (cd $DIR; mvn "$@")     
} 

user@host ~/project$ mvn-there ~/some/location install)
[ ... mvn build ... ]
user@host ~/project$

I realize this doesn't answer the specific question, but may provide you with what you're after. I'm not familiar with the Windows shell, though you should be able to reach a similar solution there as well.

Necromancing:

It's relativiely simple to emulate a COUNT DISTINCT over PARTITION BY with MAX via DENSE_RANK:

;WITH baseTable AS
(
    SELECT 'RM1' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM1' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR3' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR2' AS ADR
)
,CTE AS
(
    SELECT RM, ADR, DENSE_RANK() OVER(PARTITION BY RM ORDER BY ADR) AS dr 
    FROM baseTable
)
SELECT
     RM
    ,ADR

    ,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY ADR) AS cnt1 
    ,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM) AS cnt2 
    -- Not supported
    --,COUNT(DISTINCT CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY CTE.ADR) AS cntDist
    ,MAX(CTE.dr) OVER (PARTITION BY CTE.RM ORDER BY CTE.RM) AS cntDistEmu 
FROM CTE

Note:
This assumes the fields in question are NON-nullable fields.
If there is one or more NULL-entries in the fields, you need to subtract 1.

You can use the ToolTip class:

Creating a ToolTip for a Control

Example:

private void Form1_Load(object sender, System.EventArgs e)
{
    System.Windows.Forms.ToolTip ToolTip1 = new System.Windows.Forms.ToolTip();
    ToolTip1.SetToolTip(this.Button1, "Hello");
}

This C# function uses a regular expression to evaluate whether the passed email address is syntactically valid or not.

public static bool isValidEmail(string inputEmail)
{
   string strRegex = @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" +
         @"\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" + 
         @".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$";
   Regex re = new Regex(strRegex);
   if (re.IsMatch(inputEmail))
    return (true);
   else
    return (false);
}

I think that all previous answers are correct, this below code is very valid specially if you have to update multiple rows at once, note: it's PL/SQL

DECLARE
    CURSOR myCursor IS 
      Select contacts.BusinessCountry 
      From contacts c WHERE c.Key = t.Key;
    ---------------------------------------------------------------------
BEGIN
    FOR resultValue IN myCursor LOOP
        Update tblindiantime t
        Set CountryName=resultValue.BusinessCountry 
        where t.key=resultValue.key;
    END LOOP;
END;

I wish this could help.

You can also do the following;

string json = myJObject.ToString(Newtonsoft.Json.Formatting.None);

What you do is called a projection. That's when you return only a scalar value that belongs to one entity. You can do this with JPA. See scalar value.

I think in this case, omitting the entity type altogether is possible:

   Query query = em.createNativeQuery(  "select id from users where username = ?");  
   query.setParameter(1, "lt");  
   BigDecimal val = (BigDecimal) query.getSingleResult(); 

Example taken from here.

origin/xxx branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).

What you need to do to update the remote is to force push your local changes to master:

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master

If you are trying to delete empty spaces , try using ='' instead of is null. Hence , if your row contains empty spaces , is null will not capture those records. Empty space is not null and null is not empty space.

Dec  Hex     Binary    Char-acter Description
0    00  00000000      NUL        null

32  20  00100000      Space       space

So I recommend:

delete  from foo_table  where bar = ''

#or 

delete  from foo_table  where bar = '' or bar is null 

#or even better , 

delete from foo_table where rtrim(ltrim(isnull(bar,'')))='';

The json is kind of odd, it's like the students are properties of the "GetQuestion" object, it should be easy to be a List.....

About the libraries you could use are.

• JavaScriptSerializer
• NewtonSoft.Json
• SimpleJson ...

And there could be many more, but that are what I've used

About the json I don't now maybe something like this

public class GetQuestions
{
    public List<Student> Questions { get; set; }
}

public class Student
{
    public string Code { get; set; }
    public string Questions { get; set; }
}

void Main()
{
    var gq = new GetQuestions
    {
        Questions = new List<Student>
        {
            new Student {Code = "s1", Questions = "Q1,Q2"},
            new Student {Code = "s2", Questions = "Q1,Q2,Q3"},
            new Student {Code = "s3", Questions = "Q1,Q2,Q4"},
            new Student {Code = "s4", Questions = "Q1,Q2,Q5"},
        }
    };

    //Using Newtonsoft.json. Dump is an extension method of [Linqpad][4]
    JsonConvert.SerializeObject(gq).Dump();
}

Linqpad

and the result is this

{
     "Questions":[
        {"Code":"s1","Questions":"Q1,Q2"},
        {"Code":"s2","Questions":"Q1,Q2,Q3"},
        {"Code":"s3","Questions":"Q1,Q2,Q4"},
        {"Code":"s4","Questions":"Q1,Q2,Q5"}
      ]
 }

Yes I know the json is different, but the json that you want with dictionary.

void Main()
{
    var f = new Foo
    {
        GetQuestions = new Dictionary<string, string>
                {
                    {"s1", "Q1,Q2"},
                    {"s2", "Q1,Q2,Q3"},
                    {"s3", "Q1,Q2,Q4"},
                    {"s4", "Q1,Q2,Q4,Q6"},
                }
    };

    JsonConvert.SerializeObject(f).Dump();
}

class Foo
{
    public Dictionary<string, string> GetQuestions { get; set; }
}

And with Dictionary is as you want it.....

{
      "GetQuestions":
       {
              "s1":"Q1,Q2",
              "s2":"Q1,Q2,Q3",
              "s3":"Q1,Q2,Q4",
              "s4":"Q1,Q2,Q4,Q6"
       }
 }

Delete corrupted files from your local .m2 repository and Ctrl+F5 (Update Maven Project) in Eclipse/STS. It'll download and install these files.

A couple of issues arise when trying to reload/source ~/.profile file. [This refers to Ubuntu linux - in some cases the details of the commands will be different]

1. Are you running this directly in terminal or in a script?
2. How do you run this in a script?

Ad. 1)

Running this directly in terminal means that there will be no subshell created. So you can use either two commands:

source ~/.bash_profile

or

. ~/.bash_profile

In both cases this will update the environment with the contents of .profile file.

Ad 2) You can start any bash script either by calling

sh myscript.sh 

or

. myscript.sh

In the first case this will create a subshell that will not affect the environment variables of your system and they will be visible only to the subshell process. After finishing the subshell command none of the exports etc. will not be applied. THIS IS A COMMON MISTAKE AND CAUSES A LOT OF DEVELOPERS TO LOSE A LOT OF TIME.

In order for your changes applied in your script to have effect for the global environment the script has to be run with

.myscript.sh

command.

In order to make sure that you script is not runned in a subshel you can use this function. (Again example is for Ubuntu shell)

#/bin/bash

preventSubshell(){
  if [[ $_ != $0 ]]
  then
    echo "Script is being sourced"
  else
    echo "Script is a subshell - please run the script by invoking . script.sh command";
    exit 1;
  fi
}

I hope this clears some of the common misunderstandings! :D Good Luck!

in webkit you need to set the width to a different value, then you can set it back to the initial value
