    String match = "hello";
    String text = "0123456789hello0123456789hello";

    int j = 0;
    String indxOfmatch = "";

    for (int i = -1; i < text.length()+1; i++) {
        j =  text.indexOf("hello", i);
        if (i>=j && j > -1) {
            indxOfmatch += text.indexOf("hello", i)+" ";
        }
    }
    System.out.println(indxOfmatch);

I made a variation of Longpoke's minimalistic approach that also ensures the signatures for both callees and callers:

class EventHook(object):
    '''
    A simple implementation of the Observer-Pattern.
    The user can specify an event signature upon inizializazion,
    defined by kwargs in the form of argumentname=class (e.g. id=int).
    The arguments' types are not checked in this implementation though.
    Callables with a fitting signature can be added with += or removed with -=.
    All listeners can be notified by calling the EventHook class with fitting
    arguments.

    >>> event = EventHook(id=int, data=dict)
    >>> event += lambda id, data: print("%d %s" % (id, data))
    >>> event(id=5, data={"foo": "bar"})
    5 {'foo': 'bar'}

    >>> event = EventHook(id=int)
    >>> event += lambda wrong_name: None
    Traceback (most recent call last):
        ...
    ValueError: Listener must have these arguments: (id=int)

    >>> event = EventHook(id=int)
    >>> event += lambda id: None
    >>> event(wrong_name=0)

If you get this error in CollectionView try to create CustomCell file and Custom xib also.

add this code in ViewDidLoad() at mainVC.

PHP 7.4+; with the null coalescing assignment operator

$var ??= '';

PHP 7.0+; with the null coalescing operator

$var = $var ?? '';

PHP 5.3+; with the ternary operator shorthand

isset($var) ?: $var = '';

Or for all/older versions with isset:

$var = isset($var) ? $var : '';

or

!isset($var) && $var = '';

just remove the semicolon at the end of JAVA_HOME variable's value.

set JAVA_HOME as C:\Program Files\Java\jdk1.8.0_171

It worked for me.

DECIMAL(18,0) will allow 0 digits after the decimal point.

Use something like DECIMAL(18,4) instead that should do just fine!

That gives you a total of 18 digits, 4 of which after the decimal point (and 14 before the decimal point).

import numpy as np, cv2

You can set an ENV if you want your Time.now and DateTime.now to respond in UTC time.

require 'date'
Time.now #=> 2015-11-30 11:37:14 -0800
DateTime.now.to_s #=> "2015-11-30T11:37:25-08:00"
ENV['TZ'] = 'UTC'
Time.now #=> 2015-11-30 19:37:38 +0000
DateTime.now.to_s #=> "2015-11-30T19:37:36+00:00"

Possible alternatives:

• Rename the table SystemUser
• Use brackets
• Keep the plural table names.

IMO using brackets is technically the safest approach, though it is a bit cumbersome. IMO it's 6 of one, half-a-dozen of the other, and your solution really just boils down to personal/team preference.

In C# I did:

alert('Text\\n\\nSome more text');

It display as:

Text

Some more text

from datetime import datetime

a = datetime.strptime(f, "%Y-%m-%d")

From the mpdf site: "mPDF is a PHP class which generates PDF files from UTF-8 encoded HTML. It is based on FPDF and HTML2FPDF, with a number of enhancements."

mpdf is superior to FPDF for language handling and UTF-8 support. For CJK support it not only supports font embedding, but font subsetting (so your CJK PDFs are not oversized). TCPDF and FPDF have nothing on the UTF-8 and Font support of mpdf. It even comes with some open source fonts as of version 5.0.

You can achieve this with MAVEN_OPTS, for example
MAVEN_OPTS=-Dorg.slf4j.simpleLogger.defaultLogLevel=warn mvn clean

Rather than putting the system property directly on the command line. (At least for maven 3.3.1.)

Consider using ~/.mavenrc for setting MAVEN_OPTS if you would like logging changed for your login across all maven invocations.

Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.

CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.

If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.

I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.

Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?

In some use cases, 307 redirects might be abused by an attacker to learn the victim's credentials.

Further information can be found in section 3.1 of A Comprehensive Formal Security Analysis of OAuth 2.0.

The authors of the above paper suggest the following:

Fix. Contrary to the current wording in the OAuth standard, the exact method of the redirect is not an implementation detail but essential for the security of OAuth. In the HTTP standard (RFC 7231), only the 303 redirect is defined unambigiously to drop the body of an HTTP POST request. All other HTTP redirection status codes, including the most commonly used 302, leave the browser the option to preserve the POST request and the form data. In practice, browsers typically rewrite to a GET request, thereby dropping the form data, except for 307 redirects. Therefore, the OAuth standard should require 303 redirects for the steps mentioned above in order to fix this problem.

Yes it is definitely possible, but you will have to do

List<MyEnum> al = new ArrayList<MyEnum>();

You can then add elements to al: al.add(ONE) or al.add(TWO).

After six days I find the answer which make me crazy! The answer is disable proxy at web.config file:

<system.net>
  <defaultProxy> 
    <proxy usesystemdefault="False"/> 
  </defaultProxy>
</system.net>

iOS includes built in support for base64 encoding and decoding. If you look at resolv.h you should see the two functions b64_ntop and b64_pton . The Square SocketRocket library provides a reasonable example of how to use these functions from objective-c.

These functions are pretty well tested and reliable - unlike many of the implementations you may find in random internet postings. Don't forget to link against libresolv.dylib.

I found this helpful...

http://www.cmake.org/pipermail/cmake/2011-June/045222.html

From their example:

ADD_LIBRARY(boost_unit_test_framework STATIC IMPORTED)
SET_TARGET_PROPERTIES(boost_unit_test_framework PROPERTIES IMPORTED_LOCATION /usr/lib/libboost_unit_test_framework.a)
TARGET_LINK_LIBRARIES(mytarget A boost_unit_test_framework C)

Just multiply the number by 100, round, and divide the resulting number by 100.

You just had some messed up parentheses in your 2nd attempt.

var $html = $("html");

if ($html.hasClass('m320') || $html.hasClass('m768')) {

  // do stuff 

}

In case of mine, I solved it just by npm install protractor@latest -g and npm install webdriver-manager@latest. I am using chrome 80.x version. It worked for me in both Angular 4 & 6

You can use:

newinv=inventory+[add]

but using append is better since it doesn't create a new list:

inventory.append(add)

If using a StackTraceElement, use:

String fullClassName = stackTraceElement.getClassName();
String simpleClassName = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);

System.out.println(simpleClassName);

 

This will give you the space you're looking for.

You can't directly determine the location of the main script being executed. After all, sometimes the script didn't come from a file at all. For example, it could come from the interactive interpreter or dynamically generated code stored only in memory.

However, you can reliably determine the location of a module, since modules are always loaded from a file. If you create a module with the following code and put it in the same directory as your main script, then the main script can import the module and use that to locate itself.

some_path/module_locator.py:

def we_are_frozen():
    # All of the modules are built-in to the interpreter, e.g., by py2exe
    return hasattr(sys, "frozen")

def module_path():
    encoding = sys.getfilesystemencoding()
    if we_are_frozen():
        return os.path.dirname(unicode(sys.executable, encoding))
    return os.path.dirname(unicode(__file__, encoding))

some_path/main.py:

import module_locator
my_path = module_locator.module_path()

If you have several main scripts in different directories, you may need more than one copy of module_locator.

Of course, if your main script is loaded by some other tool that doesn't let you import modules that are co-located with your script, then you're out of luck. In cases like that, the information you're after simply doesn't exist anywhere in your program. Your best bet would be to file a bug with the authors of the tool.

In my case whitespaces at the end of the lines of .gitignore was the cause. So watch out for whitespaces in the .gitignore!

string str = Properties.Settings.Default.myConnectionString; 

All declarations of functions and variables in header files should be extern.

Exceptions to this rule are inline functions defined in the header and variables which - although defined in the header - will have to be local to the translation unit (the source file the header gets included into): these should be static.

In source files, extern shouldn't be used for functions and variables defined in the file. Just prefix local definitions with static and do nothing for shared definitions - they'll be external symbols by default.

The only reason to use extern at all in a source file is to declare functions and variables which are defined in other source files and for which no header file is provided.

Declaring function prototypes extern is actually unnecessary. Some people dislike it because it will just waste space and function declarations already have a tendency to overflow line limits. Others like it because this way, functions and variables can be treated the same way.

Do not create separate lists; create a list of lists:

results = []
with open('inputfile.txt') as inputfile:
    for line in inputfile:
        results.append(line.strip().split(','))

or better still, use the csv module:

import csv

results = []
with open('inputfile.txt', newline='') as inputfile:
    for row in csv.reader(inputfile):
        results.append(row)

Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.

Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append() just process that line right there.

Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:

import csv

with open('inputfile.txt', newline='') as inputfile:
    results = list(csv.reader(inputfile))

When you don’t define any constructor in your class, compiler defines default one for you, however when you declare any constructor (in your example you have already defined a parameterized constructor), compiler doesn’t do it for you.

Since you have defined a constructor in class code, compiler didn’t create default one. While creating object you are invoking default one, which doesn’t exist in class code. Then the code gives an compilation error.

For those who might be trying to create a Travis Build, the default path from which Django is installed from the requirements.txt file points to a repo whose django_extensions module has not been updated. The only workaround, for now, is to install from the master branch using pip. That is where the patch is made. But for now, we'll have to wait.

You can try this in the meantime, it might help

- pip install git+https://github.com/chibisov/drf-extensions.git@master

- pip install git+https://github.com/django-extensions/django-extensions.git@master

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

The server.contextPath or server.context-path works if

in pom.xml

1. packing should be war not jar

2. Add following dependencies

   <dependency>
       <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   <!-- Tomcat/TC server -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
    </dependency>
   

   In eclipse, right click on project --> Run as --> Spring Boot App.

$("#availability option:selected").text();

This will give you the text value of your dropdown list. You can also use .val() instead of .text() depending on what you're looking to get. Follow the link to the jQuery documentation and examples.

If you want to load modules from a path relative to where the script runs, such as from a "lib" subfolder", you need to use one of the following:

$PSScriptRoot which works when invoked as a script, such as via the PowerShell command $psISE.CurrentFile.FullPath which works when you're running inside ISE

But if you're in neither, and just typing away within a PowerShell shell, you can use:

pwd.Path

You can could assign one of the three to a variable called $base depending on the environment you're running under, like so:

$base=$(if ($psISE) {Split-Path -Path $psISE.CurrentFile.FullPath} else {$(if ($global:PSScriptRoot.Length -gt 0) {$global:PSScriptRoot} else {$global:pwd.Path})})

Then in your scripts, you can use it like so:

Import-Module $base\lib\someConstants.psm1
Import-Module $base\lib\myCoolPsModule1.psm1
#etc.

You can use Konfig for environment specific config files. It loads json or yaml config files automatically, it has default value and dynamic configuration features.

An example from Konfig repo:

File: config/app.json
----------------------------
{
    "default": {
        "port": 3000,
        "cache_assets": true,
        "secret_key": "7EHDWHD9W9UW9FBFB949394BWYFG8WE78F"
    },

    "development": {
        "cache_assets": false
    },

    "test": {
        "port": 3001
    },

    "staging": {
        "port": #{process.env.PORT},
        "secret_key": "3F8RRJR30UHERGUH8UERHGIUERHG3987GH8"
    },

    "production": {
        "port": #{process.env.PORT},
        "secret_key": "3F8RRJR30UHERGUH8UERHGIUERHG3987GH8"
    }
}

In development:

> config.app.port
3000

In production, assume we start application with $ NODE_ENV=production PORT=4567 node app.js

> config.app.port
4567

C++11 added alias declarations, which are generalization of typedef, allowing templates:

template <size_t N>
using Vector = Matrix<N, 1>;

The type Vector<3> is equivalent to Matrix<3, 1>.

In C++03, the closest approximation was:

template <size_t N>
struct Vector
{
    typedef Matrix<N, 1> type;
};

Here, the type Vector<3>::type is equivalent to Matrix<3, 1>.

Solved jQuery: Add element after another element

<script>
$( "p" ).append( "<strong>Hello</strong>" );
</script>

OR

<script type="text/javascript"> 
jQuery(document).ready(function(){
jQuery ( ".sidebar_cart" ) .append( "<a href='http://#'>Continue Shopping</a>" );
});
</script>

Use the % operator with a string:

irb(main):001:0> "%03d" % 5
=> "005"

The left-hand-side is a printf format string, and the right-hand side can be a list of values, so you could do something like:

irb(main):002:0> filename = "%s/%s.%04d.txt" % ["dirname", "filename", 23]
=> "dirname/filename.0023.txt"

Here's a printf format cheat sheet you might find useful in forming your format string. The printf format is originally from the C function printf, but similar formating functions are available in perl, ruby, python, java, php, etc.

Here's an easier way of doing this (source: here):

import matplotlib.pyplot as plt
from numpy.random import rand


fig, ax = plt.subplots()
for color in ['red', 'green', 'blue']:
    n = 750
    x, y = rand(2, n)
    scale = 200.0 * rand(n)
    ax.scatter(x, y, c=color, s=scale, label=color,
               alpha=0.3, edgecolors='none')

ax.legend()
ax.grid(True)

plt.show()

And you'll get this:

Take a look at here for legend properties

The fastest way is to modify your Manifest.xml. If for example you want to remove the logo of activity "Activity", and leave the logo in other activities, you can do the following:

<activity
      android:name=".home.XActivity"
      android:logo="@android:color/transparent"
      android:configChanges="orientation|keyboardHidden" />
 <activity
      android:name=".home.HomeActivity"
      android:configChanges="orientation|keyboardHidden" />

Based on the answers by Andrew Fox and Cebe, I turned it around and made them string extensions instead of Base64String extensions.

public static class StringExtensions
{
    public static string ToBase64(this string text)
    {
        return ToBase64(text, Encoding.UTF8);
    }

    public static string ToBase64(this string text, Encoding encoding)
    {
        if (string.IsNullOrEmpty(text))
        {
            return text;
        }

        byte[] textAsBytes = encoding.GetBytes(text);
        return Convert.ToBase64String(textAsBytes);
    }

    public static bool TryParseBase64(this string text, out string decodedText)
    {
        return TryParseBase64(text, Encoding.UTF8, out decodedText);
    }

    public static bool TryParseBase64(this string text, Encoding encoding, out string decodedText)
    {
        if (string.IsNullOrEmpty(text))
        {
            decodedText = text;
            return false;
        }

        try
        {
            byte[] textAsBytes = Convert.FromBase64String(text);
            decodedText = encoding.GetString(textAsBytes);
            return true;
        }
        catch (Exception)
        {
            decodedText = null;
            return false;
        }
    }
}

Starting Scala 2.13, the standard library provides a dedicated resource management utility: Using.

It can be used in this case with resources such as PrintWriter or BufferedWriter which extends AutoCloseable in order to write to a file and, no matter what, close the resource afterwards:

• For instance, with java.io api:

  import scala.util.Using, java.io.{PrintWriter, File}
  
  // val lines = List("hello", "world")
  Using(new PrintWriter(new File("file.txt"))) {
    writer => lines.foreach(writer.println)
  }
  

• Or with java.nio api:

  import scala.util.Using, java.nio.file.{Files, Paths}, java.nio.charset.Charset
  
  // val lines = List("hello", "world")
  Using(Files.newBufferedWriter(Paths.get("file.txt"), Charset.forName("UTF-8"))) {
    writer => lines.foreach(line => writer.write(line + "\n"))
  }
  

/prox/xxx/numa_maps gives some info there: N0=??? N1=???. But this result might be lower than the actual result, as it only count those which have been touched.

I had the same issue, what worked for me:

1. Copy your folders and files to another place, say to a folder (I changed my files recently and the commitment failed and led to the addressed problem)
2. check out a new working copy
3. copy your changed files from folder to your working copy and override existing files. Commiting / Updating should work now

If you're casting to a dropdownvalue[] when mocking data for example, compose it as an array of objects with value and display properties.

example:

[{'value': 'test1', 'display1': 'test display'},{'value': 'test2', 'display': 'test display2'},]

This is in a mouseEvent btw

If this is in a Swing GUI, then get rid of all calls to Thread.sleep(...) as doing so can put the entire GUI to sleep rendering it useless. Instead use a Swing Timer to produce any delays in the GUI while letting it still update its graphics.

You'll also want to avoid System.out.println(...) calls, except when debugging, and instead display user notifications in the GUI itself, perhaps in a status JLabel or as a message dialog.

For specifying the interesting JSON result, you add "application/json" in your request header like below:

"Accept:application/json" is a desired response format.

"Content-Type:application/json" specifies the content format of your request, but sometimes you specify both application/json and application/xml, but the quality of these might be different. Which server will send back the different response formats, look at the example:

Accept:application/json;q=0.4,application/xml;q=8

This will return XML, because XML has higher quality.

As Umesh Patil answer have comment say that there is problem. I try to edit answer and get reject. And get suggest to post new answer. This code should solve problem they have (Shashi Roy, Gaven, John Higgins).

<html> 
<head>  
<script type="text/javascript">
function CheckColors(val){
 var element=document.getElementById('othercolor');
 if(val=='others')
   element.style.display='block';
 else  
   element.style.display='none';
}

</script> 
</head>
<body>
  <select name="color" onchange='CheckColors(this.value);'> 
    <option>pick a color</option>

To select data in numerical range you can use BETWEEN which is inclusive.

SELECT JOB FROM MYTABLE WHERE ID BETWEEN 10 AND 15;

The .NET Library EPPlus implements a conversation from the string definition to the built in number. See class ExcelNumberFormat:

Change your gradle version in project setting: If you are using mac,click File->Project structure,then change gradle version,here:

And check your build.gradle of project,change dependency of gradle,like this:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.1'
    }
}

You can use the following for an awk solution -

awk '/^#/ {sub(/#.*/,"");getline;}1' inputfile

It can be treated as defensive programming approach from the compiler - the variables must be assigned before it can be used.

Be careful with

requestWindowFeature(Window.FEATURE_NO_TITLE);

If you are using any method to set the action bar as the follow:

getSupportActionBar().setHomeButtonEnabled(true);

It will cause a null pointer exception.

<?php
set_time_limit(0);
//This is the file where we save the    information
$fp = fopen (dirname(__FILE__) . '/localfile.tmp', 'w+');
//Here is the file we are downloading, replace spaces with %20
$ch = curl_init(str_replace(" ","%20",$url));
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
// write curl response to file
curl_setopt($ch, CURLOPT_FILE, $fp); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// get curl response
curl_exec($ch); 
curl_close($ch);
fclose($fp);
?>

I saw another question on just this topic recently (streaming pdf into iframe using dataurl only works in chrome).

I've constructed pdfs in the ast and streamed them to the browser. I was creating them first with fdf, then with a pdf class I wrote myself - in each case the pdf was created from data retrieved from a COM object based on a couple of of GET params passed in via the url.

From looking at your data sent recieved in the ajax call, it looks like you're nearly there. I haven't played with the code for a couple of years now and didn't document it as well as I'd have cared to, but - I think all you need to do is set the target of an iframe to be the url you get the pdf from. Though this may not work - the file that oututs the pdf may also have to outut a html response header first.

In a nutshell, this is the output code I used:

//We send to a browser
header('Content-Type: application/pdf');
if(headers_sent())
    $this->Error('Some data has already been output, can\'t send PDF file');
header('Content-Length: '.strlen($this->buffer));
header('Content-Disposition: inline; filename="'.$name.'"');
header('Cache-Control: private, max-age=0, must-revalidate');
header('Pragma: public');
ini_set('zlib.output_compression','0');
echo $this->buffer;

So, without seeing the full response text fro the ajax call I can't really be certain what it is, though I'm inclined to think that the code that outputs the pdf you're requesting may only be doig the equivalent of the last line in the above code. If it's code you have control over, I'd try setting the headers - then this way the browser can just deal with the response text - you don't have to bother doing a thing to it.

I simply constructed a url for the pdf I wanted (a timetable) then created a string that represented the html for an iframe of the desired sie, id etc that used the constructed url as it's src. As soon as I set the inner html of a div to the constructed html string, the browser asked for the pdf and then displayed it when it was received.

function  showPdfTt(studentId)
{
    var url, tgt;
    title = byId("popupTitle");
    title.innerHTML = "Timetable for " + studentId;
    tgt = byId("popupContent");
    url = "pdftimetable.php?";
    url += "id="+studentId;
    url += "&type=Student";
    tgt.innerHTML = "<iframe onload=\"centerElem(byId('box'))\" src='"+url+"' width=\"700px\" height=\"500px\"></iframe>";
}

EDIT: forgot to mention - you can send binary pdf's in this manner. The streams they contain don't need to be ascii85 or hex encoded. I used flate on all the streams in the pdf and it worked fine.

This works cross-browser, provides more accessibility and comes with less markup. ditch the div. Wrap the label

label{
     display: block; 
     height: 35px; 
     line-height: 35px; 
     border: 1px solid #000; 
}

input{margin-top:15px; height:20px}

<label for="name">Name: <input type="text" id="name" /></label>

Maybe a little late, but using different drivers altogether is overkill for a case of user error:

db.dbConnect("jdbc:sqlserver://localhost:1433/muff", "user", "pw" );

should be either one of these:

db.dbConnect("jdbc:sqlserver://localhost\muff", "user", "pw" );

(using named pipe) or:

db.dbConnect("jdbc:sqlserver://localhost:1433", "user", "pw" );

using port number directly; you can leave out 1433 because it's the default port, leaving:

db.dbConnect("jdbc:sqlserver://localhost", "user", "pw" );

You can use:

str.replace(/text/g, "replaced text");

You can check out libvideo. It's much more up-to-date than YoutubeExtractor, and is fast and clean to use.

In this simple way

char str [10] = "IAmCute";
printf ("%c",str[4]);

if you are looking for a script to avoid submitting form when some errors found, this method should work

function verifyData(){
     if (document.MyForm.FormInput.value.length == "") {
          alert("Write something!");
     }
     else {
          document.MyForm.submit();
     }
}

change the Submit Button type to "button"

<input value="Save" type="button" onClick="verifyData()">

hope this help.

You could use the GetSize function to get those information, cv.GetSize(im) would return a tuple with the width and height of the image. You can also use im.depth and img.nChan to get some more information.

And to resize an image, I would use a slightly different process, with another image instead of a matrix. It is better to try to work with the same type of data:

size = cv.GetSize(im)
thumbnail = cv.CreateImage( ( size[0] / 10, size[1] / 10), im.depth, im.nChannels)
cv.Resize(im, thumbnail)

Hope this helps ;)

First of all, it's not very tidy to mix pylab and pyplot code. What's more, pyplot style is preferred over using pylab.

Here is a slightly cleaned up code, using only pyplot functions:

from matplotlib import pyplot

a = [ pow(10,i) for i in range(10) ]

pyplot.subplot(2,1,1)
pyplot.plot(a, color='blue', lw=2)
pyplot.yscale('log')
pyplot.show()

The relevant function is pyplot.yscale(). If you use the object-oriented version, replace it by the method Axes.set_yscale(). Remember that you can also change the scale of X axis, using pyplot.xscale() (or Axes.set_xscale()).

Check my question What is the difference between ‘log’ and ‘symlog’? to see a few examples of the graph scales that matplotlib offers.

To count the number of values larger than x in any numpy array you can use:

n = len(matrix[matrix > x])

The boolean indexing returns an array that contains only the elements where the condition (matrix > x) is met. Then len() counts these values.

http://curl.haxx.se/docs/httpscripting.html

See part 6. HTTP Authentication

HTTP Authentication

HTTP Authentication is the ability to tell the server your username and password so that it can verify that you're allowed to do the request you're doing. The Basic authentication used in HTTP (which is the type curl uses by default) is plain text based, which means it sends username and password only slightly obfuscated, but still fully readable by anyone that sniffs on the network between you and the remote server.

To tell curl to use a user and password for authentication:

curl --user name:password http://www.example.com

The site might require a different authentication method (check the headers returned by the server), and then --ntlm, --digest, --negotiate or even --anyauth might be options that suit you.

Sometimes your HTTP access is only available through the use of a HTTP proxy. This seems to be especially common at various companies. A HTTP proxy may require its own user and password to allow the client to get through to the Internet. To specify those with curl, run something like:

curl --proxy-user proxyuser:proxypassword curl.haxx.se

If your proxy requires the authentication to be done using the NTLM method, use --proxy-ntlm, if it requires Digest use --proxy-digest.

If you use any one these user+password options but leave out the password part, curl will prompt for the password interactively.

Do note that when a program is run, its parameters might be possible to see when listing the running processes of the system. Thus, other users may be able to watch your passwords if you pass them as plain command line options. There are ways to circumvent this.

It is worth noting that while this is how HTTP Authentication works, very many web sites will not use this concept when they provide logins etc. See the Web Login chapter further below for more details on that.

Use std::printf and c_str() example:

std::printf("Follow this command: %s", myString.c_str());

You're not passing any credentials to sqlcmd.exe

So it's trying to authenticate you using the Windows Login credentials, but you mustn't have your SQL Server setup to accept those credentials...

When you were installing it, you would have had to supply a Server Admin password (for the sa account)

Try...

sqlcmd.exe -U sa -P YOUR_PASSWORD -S ".\SQL2008"

for reference, theres more details here...

>>> A = ['a1', 'a2', 'a3']
>>> B = ['b1', 'b2', 'b3']

>>> for x in A:
        for i in B:
            print ">" + x + "\n" + i

Outputs:

>a1
b1
>a1
b2
>a1
b3
>a2
b1
>a2
b2
>a2
b3
>a3
b1
>a3
b2
>a3
b3

A wrapper like this would work:

public class ServiceClientWrapper<ServiceType> : IDisposable
{
    private ServiceType _channel;
    public ServiceType Channel
    {
        get { return _channel; }
    }

    private static ChannelFactory<ServiceType> _channelFactory;

    public ServiceClientWrapper()
    {
        if(_channelFactory == null)
             // Given that the endpoint name is the same as FullName of contract.
            _channelFactory = new ChannelFactory<ServiceType>(typeof(T).FullName);
        _channel = _channelFactory.CreateChannel();
        ((IChannel)_channel).Open();
    }

    public void Dispose()
    {
        try
        {
            ((IChannel)_channel).Close();
        }
        catch (Exception e)
        {
            ((IChannel)_channel).Abort();
            // TODO: Insert logging
        }
    }
}

That should enable you to write code like:

ResponseType response = null;
using(var clientWrapper = new ServiceClientWrapper<IService>())
{
    var request = ...
    response = clientWrapper.Channel.MyServiceCall(request);
}
// Use your response object.

The wrapper could of course catch more exceptions if that is required, but the principle remains the same.

Try This...

Go to your notification area in the taskbar.

Right click on Bluestacks Agent>Rotate Portrait Apps>Enabled.

There are several options available..

a. Automatic - Selected By Default - It will rotate the app player in portrait mode for portrait apps.

b. Disabled - It will force the portrait apps to work in landscape mode.

c. Enabled - It will force the portrait apps to work in portrait mode only.

The following will do.

unsigned int x = 1;
printf ("%d", (int) (((char *)&x)[0]));

And setting &x to char * will enable you to access the individual bytes of the integer, and the ordering of bytes will depend on the endianness of the system.

I finally re-found the jupyter/IPython documentation that I was looking for.

I needed this:

from IPython.display import HTML, display

data = [[1,2,3],
        [4,5,6],
        [7,8,9],
        ]

display(HTML(
   '<table><tr>{}</tr></table>'.format(
       '</tr><tr>'.join(
           '<td>{}</td>'.format('</td><td>'.join(str(_) for _ in row)) for row in data)
       )
))

(I may have slightly mucked up the comprehensions, but display(HTML('some html here')) is what we needed)

If

1. The array is not sorted
2. Finding the min and max is done simultaneously

Then there is an algorithm that finds the min and max in 3n/2 number of comparisons. What one needs to do is process the elements of the array in pairs. The larger of the pair should be compared with the current max and the smaller of the pair should be compared with the current min. Also, one needs take special care if the array contains odd number of elements.

In c++ code (borrowing some code from Mehrdad).

struct MinMax{
   int Min,Max;
}

MinMax FindMinMax(int[] array, int start, int end) {
   MinMax  min_max;
   int index;
   int n = end - start + 1;//n: the number of elements to be sorted, assuming n>0
   if ( n%2 != 0 ){// if n is odd

     min_max.Min = array[start];
     min_max.Max = array[start];

     index = start + 1;
   }
   else{// n is even
     if ( array[start] < array[start+1] ){
       min_max.Min = array[start];
       min_max.Max = array[start+1];
     }
     else{
       min_max.Min = array[start+1];
       min_max.Max = array[start];
     }
     index = start + 2;
   }

   int big, small;
   for ( int i = index; i < n-1; i = i+2 ){
      if ( array[i] < array[i+1] ){ //one comparison
        small = array[i];
        big = array[i+1];
      }
      else{
        small = array[i+1];
        big = array[i];
      }
      if ( min_max.Min > small ){ //one comparison
        min_max.Min = small;
      }
      if ( min_max.Max < big ){ //one comparison
        min_max.Max = big;
      }
   }

   return min_max;
}

It's very easy to see that the number of comparisons it takes is 3n/2. The loop runs n/2 times and in each iteration 3 comparisons are performed. This is probably the optimum one can achieve. At this moment, I cannot point to a definite source of that. (But, I think I have seen a proof of that somewhere.)

The recursive solution given by Mehrdad above, probably also achieves this minimal number of comparisons (the last line needs to be changed). But with the same number of comparisons an iterative solution will always beat a recursive solution due to overhead in the function call as he mentioned. However, if one only cares about finding min and max of a few numbers (as Eric Belair does), no one will notice any difference in todays computer with any of the approaches above. For a large array, the difference could be significant.

Though this solution and the solution given by Matthew Brubaker has O(n) complexity, in practice one should carefully asses the hidden constants involved. The number of comparisons in his solution is 2n. The speedup gained with the solution with 3n/2 comparisons as opposed to 2n comparisons would be noticeable.

Noone cand read the file except for those who have access to the file. You must make the code readable (but not writable) by the web server. If the php code handler is running properly you can't read it by requesting by name from the web server.

If someone compromises your server you are at risk. Ensure that the web server can only write to locations it absolutely needs to. There are a few locations under /var which should be properly configured by your distribution. They should not be accessible over the web. /var/www should not be writable, but may contain subdirectories written to by the web server for dynamic content. Code handlers should be disabled for these.

Ensure you don't do anything in your php code which can lead to code injection. The other risk is directory traversal using paths containing .. or begining with /. Apache should already be patched to prevent this when it is handling paths. However, when it runs code, including php, it does not control the paths. Avoid anything that allows the web client to pass a file path.

Note: tcpdump requires root privileges, so you'll have to root your phone if not done already. Here's an ARM binary of tcpdump (this works for my Samsung Captivate). If you prefer to build your own binary, instructions are here (yes, you'd likely need to cross compile).

Also, check out Shark For Root (an Android packet capture tool based on tcpdump).

I don't believe tcpdump can monitor traffic by specific process ID. The strace method that Chris Stratton refers to seems like more effort than its worth. It would be simpler to monitor specific IPs and ports used by the target process. If that info isn't known, capture all traffic during a period of process activity and then sift through the resulting pcap with Wireshark.

You may get the following error while creating an optimized production build when using query-string module.

Failed to minify the code from this file: ./node_modules/query-string/index.js:8

To overcome this, kindly use the alternative module called stringquery which does the same process well without any issues while running the build.

import querySearch from "stringquery";

var query = querySearch(this.props.location.search);

Exceptions are a good way to handle unexpected events in your application flow. RuntimeException are unchecked by the Compiler but you may prefer to use Exceptions that extend Exception Class to control the behaviour of your api clients as they are required to catch errors for them to compile. Also forms good documentation.

If want to achieve clean interface use inheritance to subclass the different types of exception your application has and then expose the parent exception.

Here is the solution that worked for us. Not the best but maybe one can benefit.

Background:

• Our scripts were developed with VS 2013 and used NUnit VS Adapter 2.1..
• Recently we migrated to VS 2017 and when open the same solution - test wouldn't show in the Test Explorer

Upon Build we would see this message:

[Informational] NUnit Adapter 3.10.0.21: Test discovery starting
[Informational] Assembly contains no NUnit 3.0 tests: C:\ihealautomatedTests\SeleniumTest\bin\x86\Debug\SeleniumTest.dll
[Informational] NUnit Adapter 3.10.0.21: Test discovery complete

Solution (temporary):

• Uninstall NUnit Adapter 3.10...
• Install NUnit VS Adapter 2.1..

Now the Tests are shown.

this is might be a possible solution

void 0 != document.getElementById("ad") &&       (document.getElementById("ad").onclick =function(){
 var a = $("#client_id").val();
 var b = $("#contact").val();
 var c = $("#message").val();
 var Qdata = { client_id: a, contact:b, message:c }
 var respo='';
     $("#message").html('');

return $.ajax({

    url: applicationPath ,
    type: "POST",
    data: Qdata,
    success: function(e) {
         $("#mcg").html("msg send successfully");

    }

})

});

I use

            chartRange = xlWorkSheet.Rows[1];
            chartRange.Font.Bold = true;

to turn the first-row-cells-font into bold. And it works, and I am using also Excel 2007.

You can call in VBA directly

            ActiveCell.Font.Bold = True

With this code I create a timestamp in the active cell, with bold font and yellow background

           Private Sub Worksheet_SelectionChange(ByVal Target As Range)
               ActiveCell.Value = Now()
               ActiveCell.Font.Bold = True
               ActiveCell.Interior.ColorIndex = 6
           End Sub

First make sure that abc.xml is being copied to your output directory. Then you should use getResourceAsStream():

InputStream inputStream = 
    Thread.currentThread().getContextClassLoader().getResourceAsStream("test/resources/abc.xml");

Once you have the InputStream, you just need to convert it into a string. This resource spells it out: http://www.kodejava.org/examples/266.html. However, I'll excerpt the relevent code:

public String convertStreamToString(InputStream is) throws IOException {
    if (is != null) {

To write in the Visual Studio output window I used IVsOutputWindow and IVsOutputWindowPane. I included as members in my OutputWindow class which look like this :

public class OutputWindow : TextWriter
{
  #region Members

  private static readonly Guid mPaneGuid = new Guid("AB9F45E4-2001-4197-BAF5-4B165222AF29");
  private static IVsOutputWindow mOutputWindow = null;
  private static IVsOutputWindowPane mOutputPane = null;

  #endregion

  #region Constructor

  public OutputWindow(DTE2 aDte)
  {
    if( null == mOutputWindow )
    {
      IServiceProvider serviceProvider = 
      new ServiceProvider(aDte as Microsoft.VisualStudio.OLE.Interop.IServiceProvider);
      mOutputWindow = serviceProvider.GetService(typeof(SVsOutputWindow)) as IVsOutputWindow;
    }

    if (null == mOutputPane)
    {
      Guid generalPaneGuid = mPaneGuid;
      mOutputWindow.GetPane(ref generalPaneGuid, out IVsOutputWindowPane pane);

      if ( null == pane)
      {
        mOutputWindow.CreatePane(ref generalPaneGuid, "Your output window name", 0, 1);
        mOutputWindow.GetPane(ref generalPaneGuid, out pane);
      }
      mOutputPane = pane;
    }
  }

  #endregion

  #region Properties

  public override Encoding Encoding => System.Text.Encoding.Default;

  #endregion

  #region Public Methods

  public override void Write(string aMessage) => mOutputPane.OutputString($"{aMessage}\n");

  public override void Write(char aCharacter) => mOutputPane.OutputString(aCharacter.ToString());

  public void Show(DTE2 aDte)
  {
    mOutputPane.Activate();
    aDte.ExecuteCommand("View.Output", string.Empty);
  }

  public void Clear() => mOutputPane.Clear();

  #endregion
}

If you have a big text to write in output window you usually don't want to freeze the UI. In this purpose you can use a Dispatcher. To write something in output window using this implementation now you can simple do this:

Dispatcher mDispatcher = HwndSource.FromHwnd((IntPtr)mDte.MainWindow.HWnd).RootVisual.Dispatcher;

using (OutputWindow outputWindow = new OutputWindow(mDte))
{
  mDispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
  {
    outputWindow.Write("Write what you want here");
  }));
}

First off all I would like to thanks @MaximShoustin.

Thanks of you I have really nice table.

I provide some small modification in $scope.range and $scope.setPage.

In this way I have now possibility to go to the last page or come back to the first page. Also when I'm going to next or prev page the navigation is changing when $scope.gap is crossing. And the current page is not always on first position. For me it's looking more nicer.

Here is the new fiddle example: http://jsfiddle.net/qLBRZ/3/

If you want a method in which you know the algorithm, or the functions mentioned in the previous answer aren't available: convert the date to Julian Day number (which is a way of counting days from January 1st, 4713 B.C), then subtract five, then convert back to calendar date (year, month, day). Sources of the algorithms for the two conversions is section 9 of http://www.hermetic.ch/cal_stud/jdn.htm or http://en.wikipedia.org/wiki/Julian_day

That's depending if userid is a resource identifier or additional parameter. If it is then it's ok to return 404 if not you might return other code like

400 (bad request) - indicates a bad request
or
412 (Precondition Failed) e.g. conflict by performing conditional update

More info in free InfoQ Explores: REST book.

if you already deployed the code or can't change any configuration, you could remove all temp files from wsdl:

rm /tmp/wsdl-*

is_numeric() tests whether a value is a number. It doesn't necessarily have to be an integer though - it could a decimal number or a number in scientific notation.

The preg_match() example you've given only checks that a value contains the digits zero to nine; any number of them, and in any sequence.

Note that the regular expression you've given also isn't a perfect integer checker, the way you've written it. It doesn't allow for negatives; it does allow for a zero-length string (ie with no digits at all, which presumably shouldn't be valid?), and it allows the number to have any number of leading zeros, which again may not be the intended.

[EDIT]

As per your comment, a better regular expression might look like this:

/^[1-9][0-9]*$/

This forces the first digit to only be between 1 and 9, so you can't have leading zeros. It also forces it to be at least one digit long, so solves the zero-length string issue.

You're not worried about negatives, so that's not an issue.

You might want to restrict the number of digits, because as things stand, it will allow strings that are too big to be stored as integers. To restrict this, you would change the star into a length restriction like so:

/^[1-9][0-9]{0,15}$/

This would allow the string to be between 1 and 16 digits long (ie the first digit plus 0-15 further digits). Feel free to adjust the numbers in the curly braces to suit your own needs. If you want a fixed length string, then you only need to specify one number in the braces.

Hope that helps.

curl_exec is necessary. Try CURLOPT_NOBODY to not download the body. That might be faster.

a piece of code who work with python to read rs232 just in case somedoby else need it

ser = serial.Serial('/dev/tty.usbserial', 9600, timeout=0.5)
ser.write('*99C\r\n')
time.sleep(0.1)
ser.close()

Put this code in a static class> public static class ClassName{ }

public static DateTime ToDateTime(this string datetime, char dateSpliter = '-', char timeSpliter = ':', char millisecondSpliter = ',')
{
   try
   {
      datetime = datetime.Trim();
      datetime = datetime.Replace("  ", " ");
      string[] body = datetime.Split(' ');
      string[] date = body[0].Split(dateSpliter);
      int year = date[0].ToInt();
      int month = date[1].ToInt();
      int day = date[2].ToInt();
      int hour = 0, minute = 0, second = 0, millisecond = 0;
      if (body.Length == 2)
      {
         string[] tpart = body[1].Split(millisecondSpliter);
         string[] time = tpart[0].Split(timeSpliter);
         hour = time[0].ToInt();
         minute = time[1].ToInt();
         if (time.Length == 3) second = time[2].ToInt();
         if (tpart.Length == 2) millisecond = tpart[1].ToInt();
      }
      return new DateTime(year, month, day, hour, minute, second, millisecond);
   }
   catch
   {
      return new DateTime();
   }
}

In this way, you can use

string datetime = "2009-05-08 14:40:52,531";
DateTime dt0 = datetime.TToDateTime();

DateTime dt1 = "2009-05-08 14:40:52,531".ToDateTime();
DateTime dt5 = "2009-05-08".ToDateTime();
DateTime dt2 = "2009/05/08 14:40:52".ToDateTime('/');
DateTime dt3 = "2009/05/08 14.40".ToDateTime('/', '.');
DateTime dt4 = "2009-05-08 14:40-531".ToDateTime('-', ':', '-');

I tried several solutions above, but none solved my problem. Solution to refresh a subform in a form after saving data to database:

Me.subformname.Requery

It worked fine for me. Good luck.

Go to file->export->JAR file, there you may select "Export generated class files and sources" and make sure that your project is selected, and all folder under there are also! Good luck!

EDIT: A more generic way of doing this that doesn't rely on the layout type (other than that it is a layout type which supports margins):

public static void setMargins (View v, int l, int t, int r, int b) {
    if (v.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
        ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) v.getLayoutParams();
        p.setMargins(l, t, r, b);
        v.requestLayout();
    }
}

You should check the docs for TextView. Basically, you'll want to get the TextView's LayoutParams object, and modify the margins, then set it back to the TextView. Assuming it's in a LinearLayout, try something like this:

TextView tv = (TextView)findViewById(R.id.my_text_view);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)tv.getLayoutParams();
params.setMargins(0, 0, 10, 0); //substitute parameters for left, top, right, bottom
tv.setLayoutParams(params);

I can't test it right now, so my casting may be off by a bit, but the LayoutParams are what need to be modified to change the margin.

NOTE

Don't forget that if your TextView is inside, for example, a RelativeLayout, one should use RelativeLayout.LayoutParams instead of LinearLayout.LayoutParams

This works too

 var i = 1;_x000D_
 $('button').click(function() {_x000D_
     $('#red').clone().appendTo('#test').prop('id', 'red' + i);_x000D_
     i++; _x000D_
 });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>_x000D_
<div id="test">_x000D_
  <button>Clone</button>_x000D_
  <div class="red" id="red">_x000D_
  </div>_x000D_
</div>_x000D_
_x000D_
<style>_x000D_
  .red {_x000D_
    width:20px;_x000D_
    height:20px;_x000D_
    background-color: red;_x000D_
    margin: 10px;_x000D_
  }_x000D_
</style>

 if (true)
 {
   return View();
 }
 else
 {
   return View("another view name");
 }

A little editing about the code of Schnalle

<?php
$ids     = array(1, 2, 3, 7, 8, 9);
$inQuery = implode(',', array_fill(0, count($ids)-1, '?'));

$db   = new PDO(...);
$stmt = $db->prepare(
    'SELECT *
     FROM table
     WHERE id IN(' . $inQuery . ')'
);

foreach ($ids as $k => $id)
    $stmt->bindValue(($k+1), $id);

$stmt->execute();
?>

//implode(',', array_fill(0, count($ids)-1), '?')); 
//'?' this should be inside the array_fill
//$stmt->bindValue(($k+1), $in); 
// instead of $in, it should be $id

The other answers here fail to spell out a full solution for regex versions which don't support non-greedy matching. The greedy quantifiers (.*?, .+? etc) are a Perl 5 extension which isn't supported in traditional regular expressions.

If your stopping condition is a single character, the solution is easy; instead of

a(.*?)b

you can match

a[^ab]*b

i.e specify a character class which excludes the starting and ending delimiiters.

In the more general case, you can painstakingly construct an expression like

start(|[^e]|e(|[^n]|n(|[^d])))end

to capture a match between start and the first occurrence of end. Notice how the subexpression with nested parentheses spells out a number of alternatives which between them allow e only if it isn't followed by nd and so forth, and also take care to cover the empty string as one alternative which doesn't match whatever is disallowed at that particular point.

Of course, the correct approach in most cases is to use a proper parser for the format you are trying to parse, but sometimes, maybe one isn't available, or maybe the specialized tool you are using is insisting on a regular expression and nothing else.

Just a different way of listing/reading files from a jar URL and it does it recursively for nested jars

https://gist.github.com/trung/2cd90faab7f75b3bcbaa

URL urlResource = Thead.currentThread().getContextClassLoader().getResource("foo");
JarReader.read(urlResource, new InputStreamCallback() {
    @Override
    public void onFile(String name, InputStream is) throws IOException {
        // got file name and content stream 
    }
});

There is no way built in to do this. You can try this:

private static readonly char[] whitespace = new char[] { ' ', '\n', '\t', '\r', '\f', '\v' };
public static string Normalize(string source)
{
   return String.Join(" ", source.Split(whitespace, StringSplitOptions.RemoveEmptyEntries));
}

This will remove leading and trailing whitespce as well as collapse any internal whitespace to a single whitespace character. If you really only want to collapse spaces, then the solutions using a regular expression are better; otherwise this solution is better. (See the analysis done by Jon Skeet.)

This code works for me:

import groovy.io.FileType

def list = []

def dir = new File("path_to_parent_dir")
dir.eachFileRecurse (FileType.FILES) { file ->
  list << file
}

Afterwards the list variable contains all files (java.io.File) of the given directory and its subdirectories:

list.each {
  println it.path
}

This variant looks more simple and elegant.

CollectionType typeReference =
    TypeFactory.defaultInstance().constructCollectionType(List.class, Dto.class);
List<Dto> resultDto = objectMapper.readValue(content, typeReference);

Many people prefer to use just .keep since the convention has nothing to do with git.

Heuristics are algorithms, so in that sense there is none, however, heuristics take a 'guess' approach to problem solving, yielding a 'good enough' answer, rather than finding a 'best possible' solution.

A good example is where you have a very hard (read NP-complete) problem you want a solution for but don't have the time to arrive to it, so have to use a good enough solution based on a heuristic algorithm, such as finding a solution to a travelling salesman problem using a genetic algorithm.

GitHub Repositories are used to store all the files, folders and other resources which you care about.

Git Project : It is also one of the Resource in Git Repository and main use of it is to manage the projects with a visual board. If you create a project in Git Repository it create a visual board like a Kanban board to manage the project.

In this way, you can have multiple projects in a repository.

My solution without js and without images is this:

*HTML:

<input type=Submit class=continue_shopping_2 
name=Register title="Confirm Your Data!" 
value="confirm your data">

*CSS:

.continue_shopping_2:hover{
background-color:#FF9933;
text-decoration:none;
color:#FFFFFF;}


.continue_shopping_2{
padding:0 0 3px 0;
cursor:pointer;
background-color:#EC5500;
display:block;
text-align:center;
margin-top:8px;
width:174px;
height:21px;
border-radius:5px;
border-width:1px;
border-style:solid;
border-color:#919191;
font-family:Verdana;
font-size:13px;
font-style:normal;
line-height:normal;
font-weight:bold;
color:#FFFFFF;}

You can directly use the equality operator

<script>
    var firstName;
    var lastName = null;
    /* Since null == undefined is true, the following statements will catch both null and undefined */
        if(firstName == null){
            alert('Variable "firstName" is undefined.');
        }    
        if(lastName == null){
           alert('Variable "lastName" is null.');
        }
</script>

OK, I've solved this with some help from ES support. Issue the following command to the API on all nodes (or the nodes you believe to be the cause of the problem):

curl -XPUT 'localhost:9200/<index>/_settings' \
    -d '{"index.routing.allocation.disable_allocation": false}'

where <index> is the index you believe to be the culprit. If you have no idea, just run this on all nodes:

curl -XPUT 'localhost:9200/_settings' \
    -d '{"index.routing.allocation.disable_allocation": false}'

I also added this line to my yaml config and since then, any restarts of the server/service have been problem free. The shards re-allocated back immediately.

FWIW, to answer an oft sought after question, set MAX_HEAP_SIZE to 30G unless your machine has less than 60G RAM, in which case set it to half the available memory.

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

A generic solution especially for Windows Edge browser (as the -ms-user-select: none; CSS rule doesn't work):

window.ondragstart = function() {return false}

Note: This can save you having to add draggable="false" to every img tag when you still need the click event (i.e. you can't use pointer-events: none), but don't want the drag icon image to appear.

As has been mentioned, slicing with None or with np.newaxes is a great way to do this. Another alternative is to use transposes and broadcasting, as in

(data.T - vector).T

and

(data.T / vector).T

For higher dimensional arrays you may want to use the swapaxes method of NumPy arrays or the NumPy rollaxis function. There really are a lot of ways to do this.

For a fuller explanation of broadcasting, see http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html

No.

JSON is purely meant to be a data description language. As noted on http://www.json.org, it is a "lightweight data-interchange format." - not a programming language.

Per http://en.wikipedia.org/wiki/JSON, the "basic types" supported are:

• Number (integer, real, or floating point)
• String (double-quoted Unicode with backslash escaping)
• Boolean (true and false)
• Array (an ordered sequence of values, comma-separated and enclosed in square brackets)
• Object (collection of key:value pairs, comma-separated and enclosed in curly braces)
• null

As the answer seems already been answered, there is not much to add but I would like to add one thing to the existing answers. This was the way of loading class for JDBC driver for mysql

com.mysql.jdbc.Driver

But this is deprecated now. The new driver class is now

com.mysql.cj.jdbc.Driver

Also the driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

Follow the Instructions from the Ruby Installer Developer Kit Wiki:

1. Download Ruby 1.9.3 from rubyinstaller.org
2. Download DevKit file from rubyinstaller.org
   • For Ruby 1.9.3 use DevKit-tdm-32-4.5.2-20110712-1620-sfx.exe
3. Extract DevKit to path C:\Ruby193\DevKit
4. Run cd C:\Ruby193\DevKit
5. Run ruby dk.rb init
6. Run ruby dk.rb review
7. Run ruby dk.rb install

To return to the problem at hand, you should be able to install JSON (or otherwise test that your DevKit successfully installed) by running the following commands which will perform an install of the JSON gem and then use it:

gem install json --platform=ruby
ruby -rubygems -e "require 'json'; puts JSON.load('[42]').inspect"

In one project we addressed this using JSONObject (maven dependency info). We chose this because we preferred returning a simple String rather than a wrapper object. An internal helper class could easily be used instead if you don't want to add a new dependency.

Example Usage:

@RestController
public class TestController
{
    @RequestMapping("/getString")
    public String getString()
    {
        return JSONObject.quote("Hello World");
    }
}

Here's an elegant array formula (which I found here http://www.excel-easy.com/examples/count-unique-values.html) that does the trick nicely:

Type

=SUM(1/COUNTIF(List,List))

and confirm with CTRL-SHIFT-ENTER

string[] strArray = { "text1", "text2", "text3", "text4" };
string value = "text3";

if(Array.contains(strArray , value))
{
    // Do something if the value is available in Array.
}

Pre C# 6.0 solution

You can use this to get a name of any provided member:

public static class MemberInfoGetting
{
    public static string GetMemberName<T>(Expression<Func<T>> memberExpression)
    {
        MemberExpression expressionBody = (MemberExpression)memberExpression.Body;
        return expressionBody.Member.Name;
    }
}

To get name of a variable:

string testVariable = "value";
string nameOfTestVariable = MemberInfoGetting.GetMemberName(() => testVariable);

To get name of a parameter:

public class TestClass
{
    public void TestMethod(string param1, string param2)
    {
        string nameOfParam1 = MemberInfoGetting.GetMemberName(() => param1);
    }
}

C# 6.0 and higher solution

You can use the nameof operator for parameters, variables and properties alike:

string testVariable = "value";
string nameOfTestVariable = nameof(testVariable);

I have another example of something that caused this. Hopefully it helps for future reference. I'm using AngularJS 1.4.1.

I had this markup with multiple calls to a custom directive:

<div ng-controller="SomeController">
    <myDirective data="myData.Where('IsOpen',true)"></myDirective>
    <myDirective data="myData.Where('IsOpen',false)"></myDirective>
</div>

myData is an array and Where() is an extension method that iterates over the array returning a new array containing any items from the original where the IsOpen property matches the bool value in the second parameter.

In the controller I set $scope.data like this:

DataService.getData().then(function(results){
    $scope.data = results;
});

Calling the Where() extension method from the directive like in the above markup was the problem. To fix this issue I moved the call to the extension method into the controller instead of the markup:

<div ng-controller="SomeController">
    <myDirective data="openData"></myDirective>
    <myDirective data="closedData"></myDirective>
</div>

and the new controller code:

DataService.getData().then(function(results){
    $scope.openData = results.Where('IsOpen',true);
    $scope.closedData = results.Where('IsOpen',false);
});

I know this is an old question but since it appears to be unanswered to the OPs liking. There is an app that accopmlishes this in the Android Market Screencast link

I think you can use asset('/')

Window-->Web Browser--> Firefox

Use limit and offset in your queries and fill your tableview with that content. When the user scrolls down, load the next offset.

Implement the tableView:willDisplayCell:forRowAtIndexPath: method in your UITableViewDelegate and check to see if it's the last row

This query:

SELECT ROW_NUMBER() OVER(ORDER BY UserId) From Users WHERE UserName='Joe'

will return all rows where the UserName is 'Joe' UNLESS you have no UserName='Joe'

They will be listed in order of UserID and the row_number field will start with 1 and increment however many rows contain UserName='Joe'

If it does not work for you then your WHERE command has an issue OR there is no UserID in the table. Check spelling for both fields UserID and UserName.

Building on @ddilsaver's answer. I wanted to be able to use a sprite for the bullet. This appears to work:

li {
  list-style: none;
  position: relative;
}

li:before {
  content:'';
  display: block;
  position: absolute;
  width: 20px;
  height: 20px;
  left: -30px;
  top: 5px;
  background-image: url(i20.png); 
  background-position: 0px -40px; /* or whatever offset you want */
}

The key is whether you are writing a single concatenation all in one place or accumulating it over time.

For the example you gave, there's no point in explicitly using StringBuilder. (Look at the compiled code for your first case.)

But if you are building a string e.g. inside a loop, use StringBuilder.

To clarify, assuming that hugeArray contains thousands of strings, code like this:

...
String result = "";
for (String s : hugeArray) {
    result = result + s;
}

is very time- and memory-wasteful compared with:

...
StringBuilder sb = new StringBuilder();
for (String s : hugeArray) {
    sb.append(s);
}
String result = sb.toString();

I experienced a similar issue on Ubuntu 14.04 LTS after a MySQL update.

I started getting error: "Fatal error: Can't open and lock privilege tables: Incorrect file format 'user'" in /var/log/mysql/error.log

MySQL could not start.

I resolved it by removing the following directory: /var/lib/mysql/mysql

sudo rm -rf /var/lib/mysql/mysql

This leaves your other DB related files in place, only removing the mysql related files.

After running these:

sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean

Then reinstalling mysql:

sudo apt-get install mysql-server

It worked perfectly.

Standard C doesn't define binary constants. There's a GNU (I believe) extension though (among popular compilers, clang adapts it as well): the 0b prefix:

int foo = 0b1010;

If you want to stick with standard C, then there's an option: you can combine a macro and a function to create an almost readable "binary constant" feature:

#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
        unsigned long long i = 0;
        while (*s) {
                i <<= 1;
                i += *s++ - '0';
        }
        return i;
}

And then you can use it like this:

int foo = B(1010);

If you turn on heavy compiler optimizations, the compiler will most likely eliminate the function call completely (constant folding) or will at least inline it, so this won't even be a performance issue.

Proof:

The following code:

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


#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
    unsigned long long i = 0;
    while (*s) {
        i <<= 1;
        i += *s++ - '0';
    }
    return i;
}

int main()
{
    int foo = B(001100101);

    printf("%d\n", foo);

    return 0;
}

has been compiled using clang -o baz.S baz.c -Wall -O3 -S, and it produced the following assembly:

    .section    __TEXT,__text,regular,pure_instructions
    .globl  _main
    .align  4, 0x90

So clang completely eliminated the call to the function, and replaced its return value with 101. Neat, huh?

Consider some pros and cons of the second approach:

• 0 {{lastUpdated}} instead of {{timerData.lastUpdated}}, which could just as easily be {{timer.lastUpdated}}, which I might argue is more readable (but let's not argue... I'm giving this point a neutral rating so you decide for yourself)

• +1 It may be convenient that the controller acts as a sort of API for the markup such that if somehow the structure of the data model changes you can (in theory) update the controller's API mappings without touching the html partial.

• -1 However, theory isn't always practice and I usually find myself having to modify markup and controller logic when changes are called for, anyway. So the extra effort of writing the API negates it's advantage.

• -1 Furthermore, this approach isn't very DRY.

• -1 If you want to bind the data to ng-model your code become even less DRY as you have to re-package the $scope.scalar_values in the controller to make a new REST call.

• -0.1 There's a tiny performance hit creating extra watcher(s). Also, if data properties are attached to the model that don't need to be watched in a particular controller they will create additional overhead for the deep watchers.

• -1 What if multiple controllers need the same data models? That means that you have multiple API's to update with every model change.

$scope.timerData = Timer.data; is starting to sound mighty tempting right about now... Let's dive a little deeper into that last point... What kind of model changes were we talking about? A model on the back-end (server)? Or a model which is created and lives only in the front-end? In either case, what is essentially the data mapping API belongs in the front-end service layer, (an angular factory or service). (Note that your first example--my preference-- doesn't have such an API in the service layer, which is fine because it's simple enough it doesn't need it.)

In conclusion, everything does not have to be decoupled. And as far as decoupling the markup entirely from the data model, the drawbacks outweigh the advantages.

Controllers, in general shouldn't be littered with $scope = injectable.data.scalar's. Rather, they should be sprinkled with $scope = injectable.data's, promise.then(..)'s, and $scope.complexClickAction = function() {..}'s

As an alternative approach to achieve data-decoupling and thus view-encapsulation, the only place that it really makes sense to decouple the view from the model is with a directive. But even there, don't $watch scalar values in the controller or link functions. That won't save time or make the code any more maintainable nor readable. It won't even make testing easier since robust tests in angular usually test the resulting DOM anyway. Rather, in a directive demand your data API in object form, and favor using just the $watchers created by ng-bind.

UPDATE: I've finally come back to this question to add that I don't think that either approach is "wrong". Originally I had written that Josh David Miller's answer was incorrect, but in retrospect his points are completely valid, especially his point about separation of concerns.

Separation of concerns aside (but tangentially related), there's another reason for defensive copying that I failed to consider. This question mostly deals with reading data directly from a service. But what if a developer on your team decides that the controller needs to transform the data in some trivial way before the view displays it? (Whether controllers should transform data at all is another discussion.) If she doesn't make a copy of the object first she might unwittingly cause regressions in another view component which consumes the same data.

What this question really highlights are architectural shortcomings of the typical angular application (and really any JavaScript application): tight coupling of concerns, and object mutability. I have recently become enamored with architecting application with React and immutable data structures. Doing so solves the following two problems wonderfully:

1. Separation of concerns: A component consumes all of it's data via props and has little-to-no reliance on global singletons (such as Angular services), and knows nothing about what happened above it in the view hierarchy.

2. Mutability: All props are immutable which eliminates the risk of unwitting data mutation.

Angular 2.0 is now on track to borrow heavily from React to achieve the two points above.

You cannot cause the user's browser to send email silently. That would be a horrible security problem as any website could use their system as a spam relay and/or harvest their email address.

You need to make an HTTP request to a server side process (written in the language of your choice) which sends the mail from your server.

You have to make sure your DLL is in the classpath.

One such way to do so is to put the path to the DLL in PATH environment variable.

Other option is to add it to the VM arguments in the variable LD_LIBRARY_PATH, like this:

java -Djava.library.path=/path/to/my/dll -cp /my/classpath/goes/here MainClass

As previously mentioned: Classes are reference type while Structs are value types with all the consequences.

As a thumb of rule Framework Design Guidelines recommends using Structs instead of classes if:

• It has an instance size under 16 bytes
• It logically represents a single value, similar to primitive types (int, double, etc.)
• It is immutable
• It will not have to be boxed frequently

If you are writing a module in your own code for a specific usage, majkinetor's method MIGHT have worked. But there are some problems.

First, the official document does NOT guarantee that the GetHashCode() returns an unique identifier (see Object.GetHashCode Method ()):

You should not assume that equal hash codes imply object equality.

Second, assume you have a very small amount of objects so that GetHashCode() will work in most cases, this method can be overridden by some types.
For example, you are using some class C and it overrides GetHashCode() to always return 0. Then every object of C will get the same hash code. Unfortunately, Dictionary, HashTable and some other associative containers will make use this method:

A hash code is a numeric value that is used to insert and identify an object in a hash-based collection such as the Dictionary<TKey, TValue> class, the Hashtable class, or a type derived from the DictionaryBase class. The GetHashCode method provides this hash code for algorithms that need quick checks of object equality.

So, this approach has great limitations.

And even more, what if you want to build a general purpose library? Not only are you not able to modify the source code of the used classes, but their behavior is also unpredictable.

I appreciate that Jon and Simon have posted their answers, and I will post a code example and a suggestion on performance below.

In my test, the ObjectIDGenerator will throw an exception to complain that there are too many objects when creating 10,000,000 objects (10x than in the code above) in the for loop.

Also, the benchmark result is that the ConditionalWeakTable implementation is 1.8x faster than the ObjectIDGenerator implementation.

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

In addition to the answer given by @l0b0 I just had the situation where I needed to both keep any trailing newlines output by the script and check the script's return code. And the problem with l0b0's answer is that the 'echo x' was resetting $? back to zero... so I managed to come up with this very cunning solution:

RESULTX="$(./myscript; echo x$?)"
RETURNCODE=${RESULTX##*x}
RESULT="${RESULTX%x*}"

The order of execution is:

1. A's constructor
2. B's constructor

The assignment occurs in B's constructor after A's constructor—_super—has been called:

function B() {
    _super.apply(this, arguments);   // MyvirtualMethod called in here
    this.testString = "Test String"; // testString assigned here
}

So the following happens:

var b = new B();     // undefined
b.MyvirtualMethod(); // "Test String"

You will need to change your code to deal with this. For example, by calling this.MyvirtualMethod() in B's constructor, by creating a factory method to create the object and then execute the function, or by passing the string into A's constructor and working that out somehow... there's lots of possibilities.

• Choose type of iterator which fits your container: input, output, forward etc.
• Use base iterator classes from standard library. For example, std::iterator with random_access_iterator_tag.These base classes define all type definitions required by STL and do other work.

• To avoid code duplication iterator class should be a template class and be parametrized by "value type", "pointer type", "reference type" or all of them (depends on implementation). For example:

  // iterator class is parametrized by pointer type
  template <typename PointerType> class MyIterator {
      // iterator class definition goes here

Since Rails 4 you can do:

User.find_by(name: 'Bob')

which is the equivalent find_by_name in Rails 3.

Use #where when #find and #find_by are not enough.

Had the exact same problem that is described herein. No matter what I did, following the above examples, to change the location of my WSDL file (in our case from a web server), it was still referencing the original location embedded within the source tree of the server process.

After MANY hours trying to debug this, I noticed that the Exception was always being thrown from the exact same line (in my case 41). Finally this morning, I decided to just send my source client code to our trade partner so they can at least understand how the code looks, but perhaps build their own. To my shock and horror I found a bunch of class files mixed in with my .java files within my client source tree. How bizarre!! I suspect these were a byproduct of the JAX-WS client builder tool.

Once I zapped those silly .class files and performed a complete clean and rebuild of the client code, everything works perfectly!! Redonculous!!

YMMV, Andrew

You can remove the warning by adding a '@' before the mysql_connect.

@mysql_connect('localhost','root','');

but as the warning is telling you, use mysqli or PDO since the mysql extension will be removed in the future.

// Doing this code, checks if the table exists and later it creates the table max. this simply works in single compilation

you can try following

int index = 0;
WebElement baseTable = driver.findElement(By.className("table gradient myPage"));
List<WebElement> tableRows = baseTable.findElements(By.tagName("tr"));
tableRows.get(index).getText();

You can also iterate over tablerows to perform any function you want.

document.referrer is not the same as the actual URL in all situations.

I have an application where I need to establish a frameset with 2 frames. One frame is known, the other is the page I am linking from. It would seem that document.referrer would be ideal because you would not have to pass the actual file name to the frameset document.

However, if you later change the bottom frame page and then use history.back() it does not load the original page into the bottom frame, instead it reloads document.referrer and as a result the frameset is gone and you are back to the original starting window.

Took me a little while to understand this. So in the history array, document.referrer is not only a URL, it is apparently the referrer window specification as well. At least, that is the best way I can understand it at this time.

nothing is zero.

The InnoDB engine does not store deleted data. As you insert and delete rows, unused space is left allocated within the InnoDB storage files. Over time, the overall space will not decrease, but over time the 'deleted and freed' space will be automatically reused by the DB server.

You can further tune and manage the space used by the engine through an manual re-org of the tables. To do this, dump the data in the affected tables using mysqldump, drop the tables, restart the mysql service, and then recreate the tables from the dump files.

No, because single-quotes even inhibit hex code replacement.

I had the same issue with Firefox. The solution was to set the proxy settings to "system proxy settings". Fiddler can only capture traffic that goes through its proxy server. Capturing was stopped because a few days ago I was tinkering with the Firefox proxy settings for another project.

It follows that using Chrome you should also check the browser proxy settings in case of problems with capturing traffic with Fiddler.

Modifying the example here:

// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

This is a solutions that takes care of single and double quotes:

<?php
$php_data = array("title"=>"Example string's with \"special\" characters");

$escaped_data = json_encode( $php_data, JSON_HEX_QUOT|JSON_HEX_APOS );
$escaped_data = str_replace("\u0022", "\\\"", $escaped_data );
$escaped_data = str_replace("\u0027", "\\'",  $escaped_data );
?>
<script>
// no need to use JSON.parse()...
var js_data = <?= $escaped_data ?>;
alert(js_data.title); // should alert `Example string's with "special" characters`
</script>

style="position:absolute"

I like using Tiny Types which would wrap either a double, BigDecimal, or int as previous answers have suggested. (I would use a double unless precision problems crop up).

A Tiny Type gives you type safety so you don't confused a double money with other doubles.

Another super clear way of doing this could be as follows:

let modifiedString = originalString
   .split('').reverse().join('')
   .replace('_', '')
   .split('').reverse().join('')

This should print out all Parameters that start with "Question".

<html><body>
<%@ page import = "java.util.*" %>
<b>Parameters:</b><br>
<%
  Enumeration parameterList = request.getParameterNames();
  while( parameterList.hasMoreElements() )
  {
    String sName = parameterList.nextElement().toString();
    if(sName.toLowerCase.startsWith("question")){
      String[] sMultiple = request.getParameterValues( sName );
      if( 1 >= sMultiple.length )
        // parameter has a single value. print it.
        out.println( sName + " = " + request.getParameter( sName ) + "<br>" );
      else
        for( int i=0; i<sMultiple.length; i++ )
          // if a paramater contains multiple values, print all of them
          out.println( sName + "[" + i + "] = " + sMultiple[i] + "<br>" );
    }
  }
%>
</body></html>

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

For completeness, the boost way would be to use boost::format

cout << boost::format("%s %s > %s") % a % b % c;

Take your pick. The boost solution has the advantage of type safety with the sprintf format (for those who find the << syntax a bit clunky).

git add -A -n will do what you want. -A adds all untracked files to the repo, -n makes it a dry-run where the add isn't performed but the status output is given listing each file that would have been added.

1) Change your .net profile from Client profile to to .Net Framework 4.0 http://msdn.microsoft.com/en-us/library/bb398202.aspx

2) Check your Embed Interop Types flag

http://weblogs.asp.net/cazzu/archive/2011/03/11/check-your-embed-interop-types-flag-when-doing-visual-studio-extensibility-work.aspx

The code you are talking about sounds like ServiceLoader, which was introduced in Java 6 to support a feature that has been defined since Java 1.3 or earlier. For performance reasons, this is the recommended approach to find interface implementations at runtime; if you need support for this in an older version of Java, I hope that you'll find my implementation helpful.

There are a couple of implementations of this in earlier versions of Java, but in the Sun packages, not in the core API (I think there are some classes internal to ImageIO that do this). As the code is simple, I'd recommend providing your own implementation rather than relying on non-standard Sun code which is subject to change.

This is the right answer

preg_match("/^[0-9]+$/", $yourstr);

This function return TRUE(1) if it matches or FALSE(0) if it doesn't

Quick Explanation :

'^' : means that it should begin with the following ( in our case is a range of digital numbers [0-9] ) ( to avoid cases like ("abdjdf125") )

'+' : means there should be at least one digit

'$' : means after our pattern the string should end ( to avoid cases like ("125abdjdf") )

The term 'slug' comes from the world of newspaper production.

It's an informal name given to a story during the production process. As the story winds its path from the beat reporter (assuming these even exist any more?) through to editor through to the "printing presses", this is the name it is referenced by, e.g., "Have you fixed those errors in the 'kate-and-william' story?".

Some systems (such as Django) use the slug as part of the URL to locate the story, an example being www.mysite.com/archives/kate-and-william.

Even Stack Overflow itself does this, with the GEB-ish^(a) self-referential https://stackoverflow.com/questions/427102/what-is-a-slug-in-django/427201#427201, although you can replace the slug with blahblah and it will still find it okay.

It may even date back earlier than that, since screenplays had "slug lines" at the start of each scene, which basically sets the background for that scene (where, when, and so on). It's very similar in that it's a precis or preamble of what follows.

On a Linotype machine, a slug was a single line piece of metal which was created from the individual letter forms. By making a single slug for the whole line, this greatly improved on the old character-by-character compositing.

Although the following is pure conjecture, an early meaning of slug was for a counterfeit coin (which would have to be pressed somehow). I could envisage that usage being transformed to the printing term (since the slug had to be pressed using the original characters) and from there, changing from the 'piece of metal' definition to the 'story summary' definition. From there, it's a short step from proper printing to the online world.

I have solved this way.

Step 1: Open Internet Information Service Manager

Step 2: Click on Application Pools in left navigation tree.

Step 3: Select your version Pool. In my case, I am using ASP .Net v4.0. If you dont have this version, select DefaultAppPool.

Step 4: Right click on step 3, and select advanced settings.

Step 5: Select Identity in properties window and click the button to change the value.

Step 6: Select Local System in Built-in accounts combo box and click ok. That's it. Now run your application. Everything works well.

Codeproject Solution : the-underlying-provider-failed-on-open

With yield you can easily describe the breakpoints between multiple tasks in a single function. That's all, there is nothing special about it.

$closure = function ($injected1, $injected2, ...){
    $returned = array();
    //task1 on $injected1
    $returned[] = $returned1;
//I need a breakpoint here!!!!!!!!!!!!!!!!!!!!!!!!!
    //task2 on $injected2
    $returned[] = $returned2;
    //...
    return $returned;
};
$returned = $closure($injected1, $injected2, ...);

If task1 and task2 are highly related, but you need a breakpoint between them to do something else:

• free memory between processing database rows
• run other tasks which provide dependency to the next task, but which are unrelated by understanding the current code
• doing async calls and wait for the results
• and so on ...

then generators are the best solution, because you don't have to split up your code into many closures or mix it with other code, or use callbacks, etc... You just use yield to add a breakpoint, and you can continue from that breakpoint if you are ready.

Add breakpoint without generators:

$closure1 = function ($injected1){
    //task1 on $injected1
    return $returned1;
};
$closure2 = function ($injected2){
    //task2 on $injected2
    return $returned1;
};
//...
$returned1 = $closure1($injected1);
//breakpoint between task1 and task2
$returned2 = $closure2($injected2);
//...

Add breakpoint with generators

$closure = function (){
    $injected1 = yield;
    //task1 on $injected1
    $injected2 = (yield($returned1));
    //task2 on $injected2
    $injected3 = (yield($returned2));
    //...
    yield($returnedN);
};
$generator = $closure();
$returned1 = $generator->send($injected1);
//breakpoint between task1 and task2
$returned2 = $generator->send($injected2);
//...
$returnedN = $generator->send($injectedN);

note: It is easy to make mistake with generators, so always write unit tests before you implement them! note2: Using generators in an infinite loop is like writing a closure which has infinite length...

Copying the .jar file into the Android project's folder isn't always possible.
Especially if it's an output of another project in your workspace, and it keeps getting updated.

To solve this you'll have to add the jar as a linked file to your project, instead of importing it (which will copy it locally).

In the UI choose:

Project -> Import -> File System -> yourjar.jar -> (Options area) Advanced -> Create link in workspace.

The link is save in the .project file:

<linkedResources>
    <link>
        <name>yourjar.jar</name>
        <type>1</type>
        <locationURI>PARENT-5-PROJECT_LOC/bin/android_ndk10d_armeabi-v7a/yourjar.jar</locationURI>
    </link>
</linkedResources>

PARENT-5-PROJECT_LOC means relative to the project file, 5 directories up (../../../../../).

Then add it to the libraries:
Project -> Properties -> Java Build Path -> Libraries -> Add Jar -> yourjar.jar

In the same window choose the Order and Export tab and mark your jar so it will be added to the apk.

From the man file:

When --cached is given, the staged content has to match either the tip of the branch or the file on disk, allowing the file to be removed from just the index.

So, for a single file:

git rm --cached mylogfile.log

and for a single directory:

git rm --cached -r mydirectory

I would like to add a remark to the above solutions:

All these syntaxes work perfectly well IF YOUR COMMAND IS FOUND WITHIN THE PATH or IF THE COMMAND IS A cmdpath WITHOUT SPACES OR SPECIAL CHARACTERS.

But if you try to use an executable command located in a folder which path contains special characters then you would need to enclose your command path into double quotes (") and then the FOR /F syntax does not work.

Examples:

$ for /f "tokens=* USEBACKQ" %f in (
    `""F:\GLW7\Distrib\System\Shells and scripting\f2ko.de\folderbrowse.exe"" Hello '"F:\GLW7\Distrib\System\Shells and scripting"'`
) do echo %f
The filename, directory name, or volume label syntax is incorrect.

or

$ for /f "tokens=* USEBACKQ" %f in (
      `"F:\GLW7\Distrib\System\Shells and scripting\f2ko.de\folderbrowse.exe" "Hello World" "F:\GLW7\Distrib\System\Shells and scripting"`
) do echo %f
'F:\GLW7\Distrib\System\Shells' is not recognized as an internal or external command, operable program or batch file.

or

`$ for /f "tokens=* USEBACKQ" %f in (
     `""F:\GLW7\Distrib\System\Shells and scripting\f2ko.de\folderbrowse.exe"" "Hello World" "F:\GLW7\Distrib\System\Shells and scripting"`
) do echo %f
'"F:\GLW7\Distrib\System\Shells and scripting\f2ko.de\folderbrowse.exe"" "Hello' is not recognized as an internal or external command, operable program or batch file.

In that case, the only solution I found to use a command and store its result in a variable is to set (temporarily) the default directory to the one of command itself :

pushd "%~d0%~p0"
FOR /F "tokens=* USEBACKQ" %%F IN (
    `FOLDERBROWSE "Hello world!" "F:\GLW7\Distrib\System\Layouts (print,display...)"`
) DO (SET MyFolder=%%F)
popd
echo My selected folder: %MyFolder%

The result is then correct:

My selected folder: F:\GLW7\Distrib\System\OS install, recovery, VM\
Press any key to continue . . .

Of course in the above example, I assume that my batch script is located in the same folder as the one of my executable command so that I can use the "%~d0%~p0" syntax. If this is not your case, then you have to find a way to locate your command path and change the default directory to its path.

NB: For those who wonder, the sample command used here (to select a folder) is FOLDERBROWSE.EXE. I found it on the web site f2ko.de (http://f2ko.de/en/cmd.php).

If anyone has a better solution for that kind of commands accessible through a complex path, I will be very glad to hear of it.

I know there are already enough answers, but since this question comes up on Google searched for "detect adblock" at the topic, I wanted to provide some insight in case you're not using adsense.

Specifically, with this example you can detect if the default Adblock-list provided by Firefox Adblock is used. It takes advantage that in this blocklist there is an element blocked with the CSS id #bottomAd. If I include such an element in the page and test for it's height, I know whether adblocking is active or not:

<!-- some code before -->
<div id="bottomAd" style="font-size: 2px;">&nbsp;</div>
<!-- some code after -->

The rest is done via the usual jQuery suspect:

$(document).ready( function() {
  window.setTimeout( function() {
    var bottomad = $('#bottomAd');
    if (bottomad.length == 1) {
      if (bottomad.height() == 0) {
        // adblocker active
      } else {
        // no adblocker
      }
    }      
  }, 1);
}

As can be seen, I'm using setTimeout with at least a timeout of 1ms. I've tested this on various browsers and most of the time, directly checking for the element in ready always returned 0; no matter whether the adblocker was active or not. I was having two ideas about this: either rendering wasn't yet done or Adblock didn't kick in yet. I didn't bother to investigate further.

Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.

HTML:

<h1>Hello world!</h1>

Javascript (jQuery):

$(document).ready(function(){
  $('h1').css({ 'width':'100%', 'text-align':'center' });
  var h1 = $('h1').height();
  var h = h1/2;
  var w1 = $(window).height();
  var w = w1/2;
  var m = w - h
  $('h1').css("margin-top",m + "px")
});

This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top of the h1. The beauty of this method is that it works on multiple-line h1s.

EDIT: I modified it so that it centered it every time the window is resized.

I can't add comments to Vladimir's solution, but I think that this is more efficient also when your initial numbers could be also below 10.

This is my proposal:

int temp = test;
ArrayList<Integer> array = new ArrayList<Integer>();
do{
  array.add(temp % 10);
  temp /= 10;
} while  (temp > 1);

Remember to reverse the array.

Executing seq(1, 10, 1) does what 1:10 does. You can change the last parameter of seq, i.e. by, to be the step of whatever size you like.

> #a vector of even numbers
> seq(0, 10, by=2) # Explicitly specifying "by" only to increase readability 
> [1]  0  2  4  6  8 10

Ctrl + Alt + O (Code ? Optimize Imports...) is what you're looking for, both on Windows/Linux and macOS keymaps.

It says "Optimize", but, if configured to do so, it will also:

• organize existing imports
• remove unneeded imports
• add new required imports
• add unambiguous imports on the fly

You can tune the auto-import settings under "Settings ? Editor ? General ? Auto Import" as described by Dave.

You can also modify how the imports are auto-ordered under "Settings ? Editor ? Code Style ? Java ? Imports"

Instead of using config files you can use a configuration database with a scoped systemConfig table and add all your settings there.

CREATE TABLE [dbo].[SystemConfig]  
    (  
      [Id] [int] IDENTITY(1, 1)  
                 NOT NULL ,  
      [AppName] [varchar](128) NULL ,  
      [ScopeName] [varchar](128) NOT NULL ,  
      [Key] [varchar](256) NOT NULL ,  
      [Value] [varchar](MAX) NOT NULL ,  
      CONSTRAINT [PK_SystemConfig_ID] PRIMARY KEY NONCLUSTERED ( [Id] ASC )  
        WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,  
               IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,  
               ALLOW_PAGE_LOCKS = ON ) ON [PRIMARY]  
    )  
ON  [PRIMARY]  

GO  

SET ANSI_PADDING OFF  
GO  

ALTER TABLE [dbo].[SystemConfig] ADD  CONSTRAINT [DF_SystemConfig_ScopeName]  DEFAULT ('SystemConfig') FOR [ScopeName]  
GO 

With such configuration table you can create rows like such:

Then from your your application dal(s) wrapping EF you can easily retrieve the scoped configuration.
If you are not using dal(s) and working in the wire directly with EF, you can make an Entity from the SystemConfig table and use the value depending on the application you are on.

Use Date::toLocaleDateString.

new Date().toLocaleDateString()
= "9/13/2015"

You don't need to set innerHTML, just by writing

<p>
<script> document.write(new Date().toLocaleDateString()); </script>
</p>

will work.

P.S.

new Date().toDateString()
= "Sun Sep 13 2015"

This is not possible, it will give you a compile time error,

You can use array for this type of requirement .

I also struggled finding articles on how to just generate the token part. I never found one and wrote my own. So if it helps:

The things to do are:

• Create a new web application
• Install the following NuGet packages:
  • Microsoft.Owin
  • Microsoft.Owin.Host.SystemWeb
  • Microsoft.Owin.Security.OAuth
  • Microsoft.AspNet.Identity.Owin
• Add a OWIN startup class

Then create a HTML and a JavaScript (index.js) file with these contents:

var loginData = 'grant_type=password&[email protected]&password=test123';

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
    if (xmlhttp.readyState === 4 && xmlhttp.status === 200) {
        alert(xmlhttp.responseText);
    }
}
xmlhttp.open("POST", "/token", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(loginData);

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    <script type="text/javascript" src="index.js"></script>
</body>
</html>

The OWIN startup class should have this content:

using System;
using System.Security.Claims;
using Microsoft.Owin;
using Microsoft.Owin.Security.OAuth;
using OAuth20;
using Owin;

[assembly: OwinStartup(typeof(Startup))]

Thanks to tsunade21 the easiest way is:

 @RequestMapping(method = RequestMethod.GET)   
 public ModelAndView anyMethodNameGoesHere(Principal principal) {
        final String loggedInUserName = principal.getName();

 }
