That is because is does not exist, since it is bounded to Windows.

Use the standard functions from <stdio.h> instead, such as getc

The suggested ncurses library is good if you want to write console-based GUIs, but I don't think it is what you want.

#include <stdio.h>
// read a line into str, return length
int read_line(char str[]) {
int c, i=0;
c = getchar();
while (c != '\n' && c != EOF) { 
   str[i] = c;
   c = getchar();
   i++;
}
str[i] = '\0';
return i;
}

phpmyadmin doesn't follow the MySQL connection because it defines its proper collation in phpmyadmin config file.

So if we don't want or if we can't access server parameters, we should just force it to send results in a different format (encoding) compatible with client i.e. phpmyadmin

for example if both the MySQL connection collation and the MySQL charset are utf8 but phpmyadmin is ISO, we should just add this one before any select query sent to the MYSQL via phpmyadmin :

SET SESSION CHARACTER_SET_RESULTS =latin1;

or use this header library and write:

// |notEqaul|less|lessEqual|greater|greaterEqual
if(sweet::equal(valueA,valueB))

and don't care about signed/unsigned or different sizes

What you describe is the correct way to handle this.

You said that you want to stay in the GUI. You can usually set the execute bit through the file properties menu. You could also learn how to create a custom action for the context menu to do this for you if you're so inclined. This depends on your desktop environment of course.

If you use a more advanced editor, you can script the action to happen when the file is saved. For example (I'm only really familiar with vim), you could add this to your .vimrc to make any new file that starts with "#!/*/bin/*" executable.

au BufWritePost * if getline(1) =~ "^#!" | if getline(1) =~ "/bin/" | silent !chmod +x <afile> | endif | endif

Netbeans has great C and C++ support. Some people complain that it's bloated and slow, but I've been using it almost exclusively for personal projects and love it. The code assistance feature is one of the best I've seen.

I know this is old, but I recently faced the same issue and I managed to pick the element by accessing only the attribute like this: document.querySelector('[name="your-selector-name-here"]');

Just in case anyone would ever need this :)

What is the proper #include for the function 'sleep()'?

sleep() isn't Standard C, but POSIX so it should be:

#include <unistd.h>

For compiling the java file having dependency on a jar

javac -cp path_of_the_jar/jarName.jar className.java

For executing the class file

java -cp .;path_of_the_jar/jarName.jar className

FWIW, I got this error when I was implementing core data in to an existing project. It turned out I forgot to link CoreData.h to my project. I had already added the CoreData framework to my project but solved the issue by linking to the framework in my pre-compiled header just like Apple's templates do:

#import <Availability.h>

#ifndef __IPHONE_5_0
#warning "This project uses features only available in iOS SDK 5.0 and later."
#endif

#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
    #import <CoreData/CoreData.h>
#endif

"HTTP 415 Unsupported Media Type response" stems from Content-Type in header of your request. for example in javascript by axios:

Axios({
            method: 'post',
            headers: { 'Content-Type': 'application/json'},
            url: '/',
            data: data,  // an object u want to send
          }).then(function (response) {
            console.log(response);
          });

Just to mention that once you excluded the files from Sonar, do the same for Jacoco plugin:

<configuration>
<excludes>     
<exclude>com/acme/model/persistence/entity/TransactionEntity*</exclude>
<exclude>com/acme/model/persistence/ModelConstants.class</exclude>
</excludes>
</configuration> 

Having two primary keys at the same time, is not possible. But (assuming that you have not messed the case up with composite key), may be what you might need is to make one attribute unique.

CREATE t1(
c1 int NOT NULL,
c2 int NOT NULL UNIQUE,
...,
PRIMARY KEY (c1)
);

However note that in relational database a 'super key' is a subset of attributes which uniquely identify a tuple or row in a table. A 'key' is a 'super key' that has an additional property that removing any attribute from the key, makes that key no more a 'super key'(or simply a 'key' is a minimal super key). If there are more keys, all of them are candidate keys. We select one of the candidate keys as a primary key. That's why talking about multiple primary keys for a one relation or table is being a conflict.

Making this work reliably across platforms requires using #ifdef statements.

The below code finds the executable's path in Windows, Linux, MacOS, Solaris or FreeBSD (although FreeBSD is untested). It uses Boost 1.55.0 (or later) to simplify the code, but it's easy enough to remove if you want. Just use defines like _MSC_VER and __linux as the OS and compiler require.

#include <string>
#include <boost/predef/os.h>

#if (BOOST_OS_WINDOWS)
#  include <stdlib.h>
#elif (BOOST_OS_SOLARIS)
#  include <stdlib.h>
#  include <limits.h>
#elif (BOOST_OS_LINUX)
#  include <unistd.h>
#  include <limits.h>
#elif (BOOST_OS_MACOS)
#  include <mach-o/dyld.h>
#elif (BOOST_OS_BSD_FREE)
#  include <sys/types.h>
#  include <sys/sysctl.h>
#endif

/*
 * Returns the full path to the currently running executable,
 * or an empty string in case of failure.
 */
std::string getExecutablePath() {
    #if (BOOST_OS_WINDOWS)
        char *exePath;
        if (_get_pgmptr(&exePath) != 0)
            exePath = "";
    #elif (BOOST_OS_SOLARIS)
        char exePath[PATH_MAX];
        if (realpath(getexecname(), exePath) == NULL)
            exePath[0] = '\0';
    #elif (BOOST_OS_LINUX)
        char exePath[PATH_MAX];
        ssize_t len = ::readlink("/proc/self/exe", exePath, sizeof(exePath));
        if (len == -1 || len == sizeof(exePath))
            len = 0;
        exePath[len] = '\0';
    #elif (BOOST_OS_MACOS)
        char exePath[PATH_MAX];
        uint32_t len = sizeof(exePath);
        if (_NSGetExecutablePath(exePath, &len) != 0) {
            exePath[0] = '\0'; // buffer too small (!)
        } else {
            // resolve symlinks, ., .. if possible
            char *canonicalPath = realpath(exePath, NULL);
            if (canonicalPath != NULL) {
                strncpy(exePath,canonicalPath,len);
                free(canonicalPath);
            }
        }
    #elif (BOOST_OS_BSD_FREE)
        char exePath[2048];
        int mib[4];  mib[0] = CTL_KERN;  mib[1] = KERN_PROC;  mib[2] = KERN_PROC_PATHNAME;  mib[3] = -1;
        size_t len = sizeof(exePath);
        if (sysctl(mib, 4, exePath, &len, NULL, 0) != 0)
            exePath[0] = '\0';
    #endif
        return std::string(exePath);
}

The above version returns full paths including the executable name. If instead you want the path without the executable name, #include boost/filesystem.hpp> and change the return statement to:

return strlen(exePath)>0 ? boost::filesystem::path(exePath).remove_filename().make_preferred().string() : std::string();

To get the width and height of the viewport:

var viewportWidth = $(window).width();
var viewportHeight = $(window).height();

resize event of the page:

$(window).resize(function() {

});

Unfortunately, we do not have a "TRUNCATE TABLE" command in SQLite, but you can use SQLite's DELETE command to delete the complete data from an existing table, though it is recommended to use the DROP TABLE command to drop the complete table and re-create it once again.

You can reach main page with parent command (parent is the window) after the step you can make everything...

    function funcx() {
        var result = confirm('bla bla bla.!');
        if(result)
            //parent.location.assign("http://localhost:58250/Ekocc/" + document.getElementById('hdnLink').value + "");
            parent.location.assign("http://blabla.com/" + document.getElementById('hdnLink').value + "");
    } 

This way is much simple...

<form [formGroup]="form" (keyup.enter)="yourMethod(form.value)">

</form>

Include your image in the searchBar div, it will do the task for you

<div id="searchBar">
    <img src="img/logo.png" />                
    <input type="text" />
</div>

Thanks for the answers guys. My problem was that I changed a x64 solution in Visual Studio to 32 bit in the Configuration Manager only. I ended up just creating a new solution as 32 bit and then copying my C++ code and this error was gone. I think l00g33k and RogerAttrill's suggestions may have been the solution, but mine worked, too.

Just as an alternative solution:

For me webView.getSettings().setUserAgentString("Android WebView") did the trick.

I already had implemented INTERNET permission and WebViewClient as well as WebChromeClient

Easiest way to clear/reset the text field on click is to clear/reset the scope

<input type="text" class="form-control" ng-model="searchAll" ng-click="clearfunction(this)"/>

In Controller

$scope.clearfunction=function(event){
   event.searchAll=null;
}

I tried a couple of solution but I thing easy way like this (you are in the local folder):

#!/bin/bash
git fetch

var_local=`cat .git/refs/heads/master`
var_remote=`git log origin/master -1 | head -n1 | cut -d" " -f2`

if [ "$var_remote" = "$var_local" ]; then
    echo "Strings are equal." #1
else
    echo "Strings are not equal." #0 if you want
fi

Then you did compare local git and remote git last commit number....

In 1.0, the functionality was bound to ( and tab and shift-tab, in 2.0 tab was deprecated but still functional in some unambiguous cases completing or inspecting were competing in many cases. Recommendation was to always use shift-Tab. ( was also added as deprecated as confusing in Haskell-like syntax to also push people toward Shift-Tab as it works in more cases. in 3.0 the deprecated bindings have been remove in favor of the official, present for 18+ month now Shift-Tab.

So press Shift-Tab.

Based on the answer of @AlokThakur (thanks!):

def run_system_command(command):
    return_value = os.system(command)
    # Calculate the return value code
    return_value = int(bin(return_value).replace("0b", "").rjust(16, '0')[:8], 2)
    if return_value != 0:
        raise RuntimeError(f'The system command\n{command}\nexited with return code {return_value}')

Saving large files

Long data URIs can give performance problems in browsers. Another option to save client-side generated files, is to put their contents in a Blob (or File) object and create a download link using URL.createObjectURL(blob). This returns an URL that can be used to retrieve the contents of the blob. The blob is stored inside the browser until either URL.revokeObjectURL() is called on the URL or the document that created it is closed. Most web browsers have support for object URLs, Opera Mini is the only one that does not support them.

Forcing a download

If the data is text or an image, the browser can open the file, instead of saving it to disk. To cause the file to be downloaded upon clicking the link, you can use the the download attribute. However, not all web browsers have support for the download attribute. Another option is to use application/octet-stream as the file's mime-type, but this causes the file to be presented as a binary blob which is especially user-unfriendly if you don't or can't specify a filename. See also 'Force to open "Save As..." popup open at text link click for pdf in HTML'.

Specifying a filename

If the blob is created with the File constructor, you can also set a filename, but only a few web browsers (including Chrome & Firefox) have support for the File constructor. The filename can also be specified as the argument to the download attribute, but this is subject to a ton of security considerations. Internet Explorer 10 and 11 provides its own method, msSaveBlob, to specify a filename.

Example code

var file;_x000D_
var data = [];_x000D_
data.push("This is a test\n");_x000D_
data.push("Of creating a file\n");_x000D_
data.push("In a browser\n");_x000D_
var properties = {type: 'text/plain'}; // Specify the file's mime-type._x000D_
try {_x000D_
  // Specify the filename using the File constructor, but ..._x000D_
  file = new File(data, "file.txt", properties);_x000D_
} catch (e) {_x000D_
  // ... fall back to the Blob constructor if that isn't supported._x000D_
  file = new Blob(data, properties);_x000D_
}_x000D_
var url = URL.createObjectURL(file);_x000D_
document.getElementById('link').href = url;

<a id="link" target="_blank" download="file.txt">Download</a>

This is merely an educated guess without seeing the rest of your HTML/CSS:

Have you applied display: block or display: inline-block to li a? If not, try it.

Otherwise, try applying the CSS3 transform rules to li instead.

I have http_proxy and https_proxy are defined. I don't want to unset and set again those environments but --noproxy '*' works perfectly for me.

curl --noproxy '*' -XGET 172.17.0.2:9200
{
  "status" : 200,
  "name" : "Medusa",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "1.5.0",
    "build_hash" : "544816042d40151d3ce4ba4f95399d7860dc2e92",
    "build_timestamp" : "2015-03-23T14:30:58Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"
}

If you want to extract from a tag then

$('.dep_buttons').text().substr(0,25)

With the mouseover event,

$(this).text($(this).text().substr(0, 25));

The above will extract the text of a tag, then extract again assign it back.

jQuery and console.log are unrelated entities, although useful when used together.

If you use a browser's built-in dev tools, console.log will log information about the object being passed to the log function.

If the console is not active, logging will not work, and may break your script. Be certain to check that the console exists before logging:

if (window.console) console.log('foo');

The shortcut form of this might be seen instead:

window.console&&console.log('foo');

There are other useful debugging functions as well, such as debug, dir and error. Firebug's wiki lists the available functions in the console api.

Try this, you can create an extension method like this:

    public static string ContentToString(this HttpContent httpContent)
    {
        var readAsStringAsync = httpContent.ReadAsStringAsync();
        return readAsStringAsync.Result;
    }

and then, simple call the extension method:

txtBlock.Text = response.Content.ContentToString();

I hope this help you ;-)

printf is great, but people forget about it.

$ for num in 1 10 100 1000 10000 100000 1000000; do printf "%10s %s\n" $num "foobar"; done
         1 foobar
        10 foobar
       100 foobar
      1000 foobar
     10000 foobar
    100000 foobar
   1000000 foobar

$ for((i=0;i<array_size;i++));
do
    printf "%10s %10d %10s" stringarray[$i] numberarray[$i] anotherfieldarray[%i]
done

Notice I used %10s for strings. %s is the important part. It tells it to use a string. The 10 in the middle says how many columns it is to be. %d is for numerics (digits).

man 1 printf for more info.

You could try to wiggle down the nesting by implementing parallel workers (like in cluster computing) instead of increasing the number of nesting function calls.

For example: you define a limited number of slots (eg. 100) and monitor the number of "workers" assigned to each/some of them. If any slots become free, you put the waiting workers "in them".

This is another alternate solution that can be implemented:

In the URL configuration:

urlpatterns = [path('runreport/<str:queryparams>', views.get)]

In the views:

list2 = queryparams.split("&")

In python the with keyword is used when working with unmanaged resources (like file streams). It is similar to the using statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally blocks.

From Python Docs:

The with statement clarifies code that previously would use try...finally blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.

The with statement is a control-flow structure whose basic structure is:

with expression [as variable]:
    with-block

The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has __enter__() and __exit__() methods).

Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with with using.

GitLab 12.1 (July 2019) introduces a difference:

"Merge Requests for Confidential Issues"

When discussing, planning and resolving confidential issues, such as security vulnerabilities, it can be particularly challenging for open source projects to remain efficient since the Git repository is public.

As of 12.1, it is now possible for confidential issues in a public project to be resolved within a streamlined workflow using the Create confidential merge request button, which helps you create a merge request in a private fork of the project.

See "Confidential issues" from issue 58583.

A similar feature exists in GitHub, but involves the creation of a special private fork, called "maintainer security advisory".

GitLab 13.5 (Oct. 2020) will add reviewers, which was already available for GitHub before.

A closure occurs when a function has access to a local variable from an enclosing scope that has finished its execution.

def make_printer(msg):
    def printer():
        print msg
    return printer

printer = make_printer('Foo!')
printer()

When make_printer is called, a new frame is put on the stack with the compiled code for the printer function as a constant and the value of msg as a local. It then creates and returns the function. Because the function printer references the msg variable, it is kept alive after the make_printer function has returned.

So, if your nested functions don't

1. access variables that are local to enclosing scopes,
2. do so when they are executed outside of that scope,

then they are not closures.

Here's an example of a nested function which is not a closure.

def make_printer(msg):
    def printer(msg=msg):
        print msg
    return printer

printer = make_printer("Foo!")
printer()  #Output: Foo!

Here, we are binding the value to the default value of a parameter. This occurs when the function printer is created and so no reference to the value of msg external to printer needs to be maintained after make_printer returns. msg is just a normal local variable of the function printer in this context.

its work for me set the User-Agent in the addRequestProperty.

URL url = new URL(<URL>);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
httpConn.addRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0");

You can try out this phone validator package. Laravel Phone

Update

I recently discovered another package Lavarel Phone Validator (stuyam/laravel-phone-validator), that uses the free Twilio phone lookup service

There are a few issues in your code

• <div [formGroup]="form"> outside of a <form> tag
• <form [formGroup]="form"> but the name of the property containing the FormGroup is loginForm therefore it should be <form [formGroup]="loginForm">
• [formControlName]="dob" which passes the value of the property dob which doesn't exist. What you need is to pass the string dob like [formControlName]="'dob'" or simpler formControlName="dob"

Plunker example

If the label immediately follows a specified input element:

input#example + label { ... }
input:checked + label { ... }

If i'm not mistaken the latest version of React Native has solved this issue of being able to dismiss the keyboard by tapping out.

<video id="myvideo">

</video>

<p onclick="toggleControls();">Toggle</p>

<script>
var video = document.getElementById("myvideo");

function toggleControls() {
  if (video.hasAttribute("controls")) {
     video.removeAttribute("controls")   
  } else {
     video.setAttribute("controls","controls")   
  }
}
</script>

Original Post

I noticed that none of these answers show that adding a Intermediate Root CA to the chain, here are some zero-config examples to play with to see that:

• https://github.com/solderjs/nodejs-ssl-example
• http://coolaj86.com/articles/how-to-create-a-csr-for-https-tls-ssl-rsa-pems/
• https://github.com/solderjs/nodejs-self-signed-certificate-example

Snippet:

var options = {
  // this is the private key only
  key: fs.readFileSync(path.join('certs', 'my-server.key.pem'))

// this must be the fullchain (cert + intermediates)
, cert: fs.readFileSync(path.join('certs', 'my-server.crt.pem'))

// this stuff is generally only for peer certificates
//, ca: [ fs.readFileSync(path.join('certs', 'my-root-ca.crt.pem'))]
//, requestCert: false
};

var server = https.createServer(options);
var app = require('./my-express-or-connect-app').create(server);
server.on('request', app);
server.listen(443, function () {
  console.log("Listening on " + server.address().address + ":" + server.address().port);
});

var insecureServer = http.createServer();
server.listen(80, function () {
  console.log("Listening on " + server.address().address + ":" + server.address().port);
});

This is one of those things that's often easier if you don't try to do it directly through connect or express, but let the native https module handle it and then use that to serve you connect / express app.

Also, if you use server.on('request', app) instead of passing the app when creating the server, it gives you the opportunity to pass the server instance to some initializer function that creates the connect / express app (if you want to do websockets over ssl on the same server, for example).

<input type="text" autocomplete="off"/>

Should work. Alternatively, use:

<form autocomplete="off" … >

for the entire form (see this related question).

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

{'document_root', settings.STATIC_ROOT} needs to be {'document_root': settings.STATIC_ROOT}

or you'll get an error like dictionary update sequence element #0 has length 6; 2 is required

public static byte[] hexToBytes(String string) {
 int length = string.length();
 byte[] data = new byte[length / 2];
 for (int i = 0; i < length; i += 2) {
  data[i / 2] = (byte)((Character.digit(string.charAt(i), 16) << 4) + Character.digit(string.charAt(i + 1), 16));
 }
 return data;
}

I recently wrote a module called keysight that translates keypress, keydown, and keyup events into characters and keys respectively.

Example:

 element.addEventListener("keydown", function(event) {
    var character = keysight(event).char
 })

Method names which are same as the class name are called constructors. Constructors do not have a return type. So correct as:

private Flow()
{
   X = x;
   Y = y;
}

Or rename the function as:

private void DoFlow()
{
   X = x;
   Y = y;
}

Though the whole code does not make any sense to me.

Another simpler solution is to use this formula in the conditional formatting (apply to column A):

=COUNTIF(B:B,A1)

After a lot of trial and error I found this solved my problems. This is used to display photos on TVs via a browser.

• It Keeps the photos aspect ratio
• Scales in vertical and horizontal
• Centers vertically and horizontal

• The only thing to watch for are really wide images. They do stretch to fill, but not by much, standard camera photos are not altered.

  Give it a try :)

*only tested in chrome so far

HTML:

<div class="frame">
  <img src="image.jpg"/>
</div>

CSS:

.frame {
  border: 1px solid red;

  min-height: 98%;
  max-height: 98%;
  min-width: 99%;
  max-width: 99%;

  text-align: center;
  margin: auto;
  position: absolute;
}
img {
  border: 1px solid blue;

  min-height: 98%;

You can also collect with an appropriate summing collector like Collectors#summingInt(ToIntFunction)

Returns a Collector that produces the sum of a integer-valued function applied to the input elements. If no elements are present, the result is 0.

For example

Stream<Obj> filtered = list.stream().filter(o -> o.field > 10);
int sum = filtered.collect(Collectors.summingInt(o -> o.field));

This one works on more than one dropdown in the same page. Furthermore, I added caret on selected item:

    $(".dropdown-menu").on('click', 'li a', function(){
        $(this).parent().parent().siblings(".btn:first-child").html($(this).text()+' <span class="caret"></span>');
        $(this).parent().parent().siblings(".btn:first-child").val($(this).text());
    });

The delimiter can be a regular expression.

awk -F'[/=]' '{print $3 "\t" $5 "\t" $8}' file

Produces:

tc0001   tomcat7.1    demo.example.com  
tc0001   tomcat7.2    quest.example.com  
tc0001   tomcat7.5    www.example.com

Your understanding is correct. The ApplicationContext is where your Spring beans live. The purpose of the ContextLoaderListener is two-fold:

1. to tie the lifecycle of the ApplicationContext to the lifecycle of the ServletContext and

2. to automate the creation of the ApplicationContext, so you don't have to write explicit code to do create it - it's a convenience function.

Another convenient thing about the ContextLoaderListener is that it creates a WebApplicationContext and WebApplicationContext provides access to the ServletContext via ServletContextAware beans and the getServletContext method.

I can recommend interesting solution for Linux fans. After I explored this solution, I've switched from DependencyWalker to this.

You can use your favorite ldd over Windows-related exe, dll.

To do this you need to install Cygwin (basic installation, without additional packages required) on your Windows and then just start Cygwin Terminal. Now you can run your favorite Linux commands, including:

$ ldd your_dll_file.dll

UPD: You can use ldd also through git bash terminal on Windows. No need to install cygwin in case if you have git already installed.

Hello from the future.

For clarity, I just wanted to add (as this was pretty high up in google) - we can now use

<button type="submit">Upload Stuff</button>

And to reset a form

<button type="reset" value="Reset">Reset</button>

Check out button types

We can also attach buttons to submit forms like this:

<button type="submit" form="myform" value="Submit">Submit</button>

The parameter ui has a property called selected which is a reference to the selected dom element, you can call innerHTML on that element.

Your code $('.ui-selected').innerHTML tries to return the innerHTML property of a jQuery wrapper element for a dom element with class ui-selected

$(function () {
    $("#select-image").selectable({
        selected: function (event, ui) {
            var $variable = ui.selected.innerHTML; // or $(ui.selected).html()
            console.log($variable);
        }
    });
});

Demo: Fiddle

You can use the package sklearn and its associated preprocessing utilities to normalize the data.

import pandas as pd
from sklearn import preprocessing

x = df.values #returns a numpy array
min_max_scaler = preprocessing.MinMaxScaler()
x_scaled = min_max_scaler.fit_transform(x)
df = pd.DataFrame(x_scaled)

For more information look at the scikit-learn documentation on preprocessing data: scaling features to a range.

You are trying to run a Python 2 codebase with Python 3. xrange() was renamed to range() in Python 3.

Run the game with Python 2 instead. Don't try to port it unless you know what you are doing, most likely there will be more problems beyond xrange() vs. range().

For the record, what you are seeing is not a syntax error but a runtime exception instead.

If you do know what your are doing and are actively making a Python 2 codebase compatible with Python 3, you can bridge the code by adding the global name to your module as an alias for range. (Take into account that you may have to update any existing range() use in the Python 2 codebase with list(range(...)) to ensure you still get a list object in Python 3):

try:
    # Python 2
    xrange
except NameError:
    # Python 3, xrange is now named range
    xrange = range

# Python 2 code that uses xrange(...) unchanged, and any
# range(...) replaced with list(range(...))

or replace all uses of xrange(...) with range(...) in the codebase and then use a different shim to make the Python 3 syntax compatible with Python 2:

try:
    # Python 2 forward compatibility
    range = xrange
except NameError:
    pass

# Python 2 code transformed from range(...) -> list(range(...)) and
# xrange(...) -> range(...).

The latter is preferable for codebases that want to aim to be Python 3 compatible only in the long run, it is easier to then just use Python 3 syntax whenever possible.

Raymond Chen has a few ideas:

https://devblogs.microsoft.com/oldnewthing/20050128-00/?p=36573

Quoted here in full because MSDN archives tend to be somewhat unreliable:

The easy way is to use the %CD% pseudo-variable. It expands to the current working directory.

set OLDDIR=%CD%
.. do stuff ..
chdir /d %OLDDIR% &rem restore current directory

(Of course, directory save/restore could more easily have been done with pushd/popd, but that's not the point here.)

The %CD% trick is handy even from the command line. For example, I often find myself in a directory where there's a file that I want to operate on but... oh, I need to chdir to some other directory in order to perform that operation.

set _=%CD%\curfile.txt
cd ... some other directory ...
somecommand args %_% args

(I like to use %_% as my scratch environment variable.)

Type SET /? to see the other pseudo-variables provided by the command processor.

Also the comments in the article are well worth scanning for example this one (via the WayBack Machine, since comments are gone from older articles):

http://blogs.msdn.com/oldnewthing/archive/2005/01/28/362565.aspx#362741

This covers the use of %~dp0:

If you want to know where the batch file lives: %~dp0

%0 is the name of the batch file. ~dp gives you the drive and path of the specified argument.

Adding to Tim's answer:

  #search:placeholder-shown {
     // show background image, I like svg 
     // when using svg, do not use HEX for colour; you can use rbg/a instead
     // also notice the single quotes
     background-image url('data:image/svg+xml; utf8, <svg>... <g fill="grey"...</svg>')
     // other background props
   }

   #search:not(:placeholder-shown) { background-image: none;}

• git checkout modifies your working tree,
• git reset modifies which reference the branch you're on points to,
• git revert adds a commit undoing changes.

If the seq command available on your system:

for i in `seq 2 $max`
do
  echo "output: $i"
done

If not, then use poor man's seq with perl:

seq=`perl -e "\$,=' ';print 2..$max"`
for i in $seq
do
  echo "output: $i"
done

Watch those quote marks.

Actually, it looks like you may be able to download language packs directly through Windows Update. Open the old Control Panel by pressing WinKey+X and clicking Control Panel. Then go to Clock, Language, and Region > Add a language. Add the desired language. Then under the language it should say "Windows display language: Available". Click "Options" and then "Download and install language pack."

I'm not sure why this functionality appears to be less accessible than it was in Windows 8.

You can append this line at the end of .bashrc file-

export PATH=$PATH:"/opt/Android/Sdk/platform-tools/"

here /opt/Android/Sdk/platform-tools/ is installation directory of Sdk. .bashrc file is located in home folder

vi ~/.bashrc

or if you have sublime installed

subl ~/.bashrc

2021 Update

I’m posting this answer since I struggled with this myself and Chrome updated their security with requiring Subject Alternative Name which a lot of posts do not have as it was not required when they were posted as an answer. I’m assuming that WAMP is already installed.

STEP 1

Download OpenSSL Light and install

Although this part is optional, but it makes it easier later to execute commands. If you skip this step, you’ll have to provide full path to openssl.exe where you will execute the command. If you prefer to set it then update the openssl.exe path in Environment Variables.

Environment Variables -> System Variables -> Path -> Edit -> New -> c:\Program Files\OpenSSL-Win64\bin

Create a folder named “key” in the c:/wamp64/bin/apache/apache2.4.27(your version number)/conf/ directory.

Create configuration file for your CA MyCompanyCA.cnf with contents (you can change it to your needs):

[ req ]
distinguished_name  = req_distinguished_name
x509_extensions     = root_ca

[ req_distinguished_name ]
countryName             = Country Name (2 letter code)
countryName_min         = 2
countryName_max         = 2
stateOrProvinceName     = State or Province Name (full name)
localityName            = Locality Name (eg, city)
0.organizationName      = Organization Name (eg, company)
organizationalUnitName  = Organizational Unit Name (eg, section)
commonName              = Common Name (eg, fully qualified host name)
commonName_max          = 64
emailAddress            = Email Address
emailAddress_max        = 64

[ root_ca ]
basicConstraints            = critical, CA:true

Create the extensions configuration file MyCompanyLocalhost.ext for your web server certificate:

subjectAltName = @alt_names
extendedKeyUsage = serverAuth

[alt_names]
DNS.1   = localhost
DNS.2   = mycy.mycompany.com

Execute these commands in the given order to generate the key and certificates:

openssl req -x509 -newkey rsa:2048 -out MyCompanyCA.cer -outform PEM -keyout MyCompanyCA.pvk -days 10000 -verbose -config MyCompanyCA.cnf -nodes -sha256 -subj "/CN=MyCompany CA"
openssl req -newkey rsa:2048 -keyout MyCompanyLocalhost.pvk -out MyCompanyLocalhost.req -subj /CN=localhost -sha256 -nodes
openssl x509 -req -CA MyCompanyCA.cer -CAkey MyCompanyCA.pvk -in MyCompanyLocalhost.req -out MyCompanyLocalhost.cer -days 10000 -extfile MyCompanyLocalhost.ext -sha256 -set_serial 0x1111

As a result, you will have MyCompanyCA.cer, MyCompanyLocalhost.cer and MyCompanyLocalhost.pvk files.

Install MyCompanyCA.cer under

Control Panel -> Manage User Certificates -> Trusted Root Certification Authorities -> Certificates

To install MyCompanyLocalhost.cer just double click it.

Open c:/wamp64/bin/apache/apache2.4.27(your version number)/conf/httpd.conf and un-comment (remove the #) the following 3 lines:

LoadModule ssl_module modules/mod_ssl.so
Include conf/extra/httpd-ssl.conf
LoadModule socache_shmcb_module modules/mod_socache_shmcb.so

Open c:/wamp64/bin/apache/apache2.4.37/conf/extra/httpd-ssl.conf and change all the parameters to the ones shown below:

Directory "c:/wamp64/www"
DocumentRoot "c:/wamp64/www"
ServerName localhost:443
ServerAdmin [email protected]
ErrorLog "c:/wamp64/bin/apache/apache2.4.27/logs/error.log"
TransferLog "c:/wamp64/bin/apache/apache2.4.27/logs/access.log"
SSLCertificateFile "c:/wamp64/bin/apache/apache2.4.27/conf/key/MyCompanyLocalhost.cer"
SSLCertificateKeyFile "c:/wamp64/bin/apache/apache2.4.27/conf/key/MyCompanyLocalhost.pvk"
SSLSessionCache "shmcb:c:/wamp64/bin/apache/apache2.4.27/logs/ssl_scache(512000)"
CustomLog "c:/wamp64/bin/apache/apache2.4.27/logs/ssl_request.log" \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

Note: This is the tricky part. If you make any small mistake while editing this file, SSL won’t work. Make a copy of it before you edit it.

Restart Wamp and Chrome. Localhost is now secure: https://localhost

You just need to declare a as a global in thread2, so that you aren't modifying an a that is local to that function.

def thread2(threadname):
    global a
    while True:
        a += 1
        time.sleep(1)

In thread1, you don't need to do anything special, as long as you don't try to modify the value of a (which would create a local variable that shadows the global one; use global a if you need to)>

def thread1(threadname):
    #global a       # Optional if you treat a as read-only
    while a < 10:
        print a

I can confirm this bug exists in VS 2012 Update 2 also.

My work-around is to:

1. Clean Solution (and do nothing else)
2. Close all open documents/files in the solution
3. Exit VS 2012
4. Run VS 2012
5. Build Solution

I don't know if this is relevant or not, but my project uses "Linked" in class files from other projects - it's a Silverlight 5 project and the only way to share a class that is .NET and SL compatible is to link the files.

Something to consider ... look for linked files across projects in a single solution.

That doesn't look like a very Angular way of doing it. I'm not entirely sure why it doesn't work, but you'd probably need to access the scope in order to use a function like that.

My suggestion would be to create a filter. That's the Angular way.

myModule.filter('ceil', function() {
    return function(input) {
        return Math.ceil(input);
    };
});

Then in your HTML do this:

<p>The percentage is {{ (100*count/total) | ceil }}%</p>

Perhaps one of the more frustrating situations I've encountered was where people insisted on prefixing Stored Procedures with the prefix "sp_".

If you don't know why this is a bad thing to do, check out this blog entry here!

In a nutshell, if SQL Server is looking for a Stored Procedure with an sp_ prefix, it will check the master database first (which it won't find unless the SP is actually in the master database). Assuming it isn't in the master DB, SQL Server assumes the SP isn't in the cache and therefore recompiles it.

It may sound like a small thing, but it adds up in high volume or busy database server environments!

Console Aliases in Windows 10

To define a console alias, use Doskey.exe to create a macro, or use the AddConsoleAlias function.

doskey

doskey test=cd \a_very_long_path\test

To also pass parameters add $* at the end: doskey short=longname $*

AddConsoleAlias

AddConsoleAlias( TEXT("test"), 
                 TEXT("cd \\<a_very_long_path>\\test"), 
                 TEXT("cmd.exe"));

More information here Console Aliases, Doskey, Parameters

If this is for debug output then OutputDebugString is what you want. A useful macro :

#define DBOUT( s )            \
{                             \
   std::ostringstream os_;    \
   os_ << s;                   \
   OutputDebugString( os_.str().c_str() );  \
}

This allows you to say things like:

DBOUT( "The value of x is " << x );

You can extend this using the __LINE__ and __FILE__ macros to give even more information.

For those in Windows and wide character land:

#include <Windows.h>
#include <iostream>
#include <sstream>

 #define DBOUT( s )            \
{                             \
   std::wostringstream os_;    \
   os_ << s;                   \
   OutputDebugStringW( os_.str().c_str() );  \
}

Comparing non-primitives (aka Objects) in Java with == compares their reference instead of their values. Long is a class and thus Long values are Objects.

The problem is that the Java Developers wanted people to use Long like they used long to provide compatibility, which led to the concept of autoboxing, which is essentially the feature, that long-values will be changed to Long-Objects and vice versa as needed. The behaviour of autoboxing is not exactly predictable all the time though, as it is not completely specified.

So to be safe and to have predictable results always use .equals() to compare objects and do not rely on autoboxing in this case:

Long num1 = 127, num2 = 127;
if(num1.equals(num2)) { iWillBeExecutedAlways(); }

According to the ControllerBase class, you can get the claims for the user executing the action.

here's how you can do it in 1 line.

var claims = User.Claims.ToList();

str.replace is the wrong function for what you want to do (apart from it being used incorrectly). You want to replace any character of a set with a space, not the whole set with a single space (the latter is what replace does). You can use translate like this:

removeSpecialChars = z.translate ({ord(c): " " for c in "!@#$%^&*()[]{};:,./<>?\|`~-=_+"})

This creates a mapping which maps every character in your list of special characters to a space, then calls translate() on the string, replacing every single character in the set of special characters with a space.

After reading the answers here I decided to use bit(1) and yes, it is somehow better in space/time, BUT after a while I changed my mind and I will never use it again. It complicated my development a lot, when using prepared statements, libraries etc (php).

Since then, I always use tinyint(1), seems good enough.

First, note that the function parameter named i and the variable named i in main() are two different variables. I think that doesn't matter that much to the present discussion, but it's important to know.

Second, you use the postincrement operator in fun(). That means the result of the expression is the value before i is incremented; the final value 11 of i is simply discarded, and the function returns 10. The variable i back in main, being a different variable, is assigned the value 10, which you then decrement to get 9.

There is a subtle issue here that is a bit of a gotcha.

The toString() method has a base implementation in Object. CharSequence is an interface; and although the toString() method appears as part of that interface, there is nothing at compile-time that will force you to override it and honor the additional constraints that the CharSequence toString() method's javadoc puts on the toString() method; ie that it should return a string containing the characters in the order returned by charAt().

Your IDE won't even help you out by reminding that you that you probably should override toString(). For example, in intellij, this is what you'll see if you create a new CharSequence implementation: http://puu.sh/2w1RJ. Note the absence of toString().

If you rely on toString() on an arbitrary CharSequence, it should work provided the CharSequence implementer did their job properly. But if you want to avoid any uncertainty altogether, you should use a StringBuilder and append(), like so:

final StringBuilder sb = new StringBuilder(charSequence.length());
sb.append(charSequence);
return sb.toString();

Even if variable values don't point back to the name, you have access to the list of every assigned variable and its value, so I'm astounded that only one person suggested looping through there to look for your var name.

Someone mentioned on that answer that you might have to walk the stack and check everyone's locals and globals to find foo, but if foo is assigned in the scope where you're calling this retrieve_name function, you can use inspect's current frame to get you all of those local variables.

My explanation might be a little bit too wordy (maybe I should've used a "foo" less words), but here's how it would look in code (Note that if there is more than one variable assigned to the same value, you will get both of those variable names):

import inspect

x,y,z = 1,2,3

def retrieve_name(var):
    callers_local_vars = inspect.currentframe().f_back.f_locals.items()
    return [var_name for var_name, var_val in callers_local_vars if var_val is var]

print retrieve_name(y)

If you're calling this function from another function, something like:

def foo(bar):
    return retrieve_name(bar)

foo(baz)

And you want the baz instead of bar, you'll just need to go back a scope further. This can be done by adding an extra .f_back in the caller_local_vars initialization.

See an example here: ideone

to stop IIS manually:

1. go to start menu
2. type in IIS

you get a search result for the manager (Internet Information Services (IIS) manager, on the right side of it there are restart/stop/start buttons.

If you don't want IIS to start on startup because its really annoying..:

1. go to start menu.
2. click control panel.
3. click programs.
4. turn windows features on or off
5. wait until the list is loaded
6. search for Internet Information Services (IIS).
7. uncheck the box.
8. Wait until it's done with the changes.
9. restart computer, but then again the info box will tell you to do that anyways (you can leave this for later if you want to).

oh and IIS and xampp basically do the same thing just in a bit different way. ANd if you have Xampp for your projects then its not really all that nessecary to leave it on if you don't ever use it anyways.

With Swift 5, you can use String's init(data:encoding:) initializer in order to convert a Data instance into a String instance using UTF-8. init(data:encoding:) has the following declaration:

init?(data: Data, encoding: String.Encoding)

Returns a String initialized by converting given data into Unicode characters using a given encoding.

The following Playground code shows how to use it:

import Foundation

let json = """
{
"firstName" : "John",
"lastName" : "Doe"
}
"""

let data = json.data(using: String.Encoding.utf8)!

let optionalString = String(data: data, encoding: String.Encoding.utf8)
print(String(describing: optionalString))

/*
 prints:
 Optional("{\n\"firstName\" : \"John\",\n\"lastName\" : \"Doe\"\n}")
*/

Here is a little code. It works (for me) at any subsequent html code change of the WebBrowser control. You may adapt it to your specific needs.

    static public void SetWebBrowserHtml(WebBrowser Browser, string HtmlText)
    {
        if (Browser != null)
        {
            if (string.IsNullOrWhiteSpace(HtmlText))
            {
                // Putting a div inside body forces control to use div instead of P (paragraph)
                // when the user presses the enter button
                HtmlText = 
                        @"<html>
                    <head>
                    <meta http-equiv=""Content-Type"" content=""text/html; charset=UTF-8"" />
                    </head>
                      <div></div>
                    <body>
                    </body>
                    </html>";
            }

            if (Browser.Document == null)
            {
                Browser.Navigate("about:blank");

                //Wait for document to finish loading
                while (Browser.ReadyState != WebBrowserReadyState.Complete)
                {
                    Application.DoEvents();
                    System.Threading.Thread.Sleep(5);
                }
            }

            // Write html code
            dynamic Doc = Browser.Document.DomDocument;
            Doc.open();
            Doc.write(HtmlText);
            Doc.close();


            // Add scripts here

                Script.id = "MyScriptFunctions";
                Script.text = JavascriptFunctionsSourcecode;
                Doc.appendChild(Script);
            }

            // Enable contentEditable   
            /*

                    Browser.Document.Body.SetAttribute("contentEditable", "true");
            }

Disable the submit button soon after a click. Make sure you handle validations properly. Also keep an intermediate page for all processing or DB operations and then redirect to next page. THis makes sure that Refreshing the second page does not do another processing.

Try setting the timeout value in your web service proxy class:

WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds

On Windows 10 with Vagrant 2.2.2, setting the environment variable VAGRANT_HOME will ensure that boxes are downloaded to a subfolder of the folder specified for VAGRANT_HOME.

In my case I set VAGRANT_HOME to e:\vagrant_home, and the boxes get stored under e:\vagrant_home\boxes.

This works for me.

That's where the boxes are stored. The virtual machines are being created in the folder configured in Virtual Box. To set the VirtualBox VM storage folder, go to: VirtualBox GUI --> File --> Preferences --> General --> Default Machine Folder.

Why are you sending it through a post if you already have it on the server (PHP) side?

Why not just save the array to the $_SESSION variable so you can use it when the form gets submitted, that might make it more "secure" since then the client cannot change the variables by editing the source.

It will depend upon how you really want to do.

I would suggest the following approach:

import {Autobind} from 'es-decorators';

export class Form extends Component {

    @Autobind

I have created a new tool to allow you to have true private methods on the prototype https://github.com/TremayneChrist/ProtectJS

Example:

var MyObject = (function () {

  // Create the object
  function MyObject() {}

  // Add methods to the prototype
  MyObject.prototype = {

    // This is our public method
    public: function () {
      console.log('PUBLIC method has been called');
    },

    // This is our private method, using (_)
    _private: function () {
      console.log('PRIVATE method has been called');
    }
  }

  return protect(MyObject);

})();

// Create an instance of the object
var mo = new MyObject();

// Call its methods
mo.public(); // Pass
mo._private(); // Fail

An equivalent that only accepts types T derived from type List looks like

template<typename T, 
         typename std::enable_if<std::is_base_of<List, T>::value>::type* = nullptr>
class ObservableList
{
    // ...
};

This is my way to find the rootstart. Create at ROOT start a file with name mainpath.php

<?php 
## DEFINE ROOTPATH
$check_data_exist = ""; 

$i_surf = 0;

// looking for mainpath.php at the aktiv folder or higher folder

while (!file_exists($check_data_exist."mainpath.php")) {
  $check_data_exist .= "../"; 
  $i_surf++;
  // max 7 folder deep
  if ($i_surf == 7) { 
   return false;
  }
}

define("MAINPATH", ($check_data_exist ? $check_data_exist : "")); 
?>

For me is that the best and easiest way to find them. ^^

Simple function:

CREATE FUNCTION [dbo].[RemoveAlphaCharacters](@InputString VARCHAR(1000))
RETURNS VARCHAR(1000)
AS
BEGIN
  WHILE PATINDEX('%[^0-9]%',@InputString)>0
        SET @InputString = STUFF(@InputString,PATINDEX('%[^0-9]%',@InputString),1,'')     
  RETURN @InputString
END

Just to addon if someone is dealing with  , this would work if dealing with  .

Replace it with str_replace() first and check it with empty()

empty(str_replace(" " ,"" , $YOUR_DATA)) ? $YOUR_DATA = '--' : $YOUR_DATA;

You need to use the scrollTop property.

document.getElementById('box').scrollTop

This is an example j is the value you want to round up.

Dim i As Integer
Dim ii, j As Double

j = 27.11
i = (j) ' i is an integer and truncates the decimal

ii = (j) ' ii retains the decimal

If ii - i > 0 Then i = i + 1 

If the remainder is greater than 0 then it rounds it up, simple. At 1.5 it auto rounds to 2 so it'll be less than 0.

This doesn't work in IE6, which may be an issue, but it'll work in IE7+ and Firefox, Safari etc. It'll align the 3rd column right and all of the subsequent columns left.

td + td + td { text-align: right; }
td + td + td + td { text-align: left; }

Heroku treats logs as time-ordered streams of events. Accessing *.log files on the filesystem is not recommended in such an environment for a variety of reasons.

First, if your app has more than one dyno then each log file only represents a partial view into the events of your app. You would have to manually aggregate all the files to get the full view.

Second, the filesystem on Heroku is ephemeral meaning whenever your dyno is restarted or moved (which happens about once a day)the log files are lost. So you only get at most a day's view into that single dyno's logs.

Finally, on the Cedar stack running heroku console or even heroku run bash does not connect you to a currently running dyno. It spawns a new one specifically for the bash command. This is called a one-off process. As such, you won't find the log files for your other dynos that are running the actual http processes on the one spawned for heroku run.

Logging, and visibility in general, is a first-class citizen on Heroku and there are several tools that address these issues. First, to see a real-time stream of application events across all dynos and all layers of the application/stack use the heroku logs -t command to tail output to your terminal.

$ heroku logs -t
2010-09-16T15:13:46-07:00 app[web.1]: Processing PostController#list (for 208.39.138.12 at 2010-09-16 15:13:46) [GET]

2010-09-16T15:13:47-07:00 app[worker.1]: 2 jobs processed at 16.6761 j/s, 0 failed ...

This works great for observing the behavior of your application right now. If you want to store the logs for longer periods of time you can use one of the many logging add-ons that provide log retention, alerting and triggers.

Lastly, if you want to store the log files yourself you can setup your own syslog drain to receive the stream of events from Heroku and post-process/analyze yourself.

Summary: Don't use heroku console or heroku run bash to view static log files. Pipe into Heroku's stream of log events for your app using heroku logs or a logging add-on.

android:keepScreenOn="true" could be better option to have from layout XML.

A lot of answers above have fields compared in single comparator method which is not actually working. There are some answers though with different comparators implemented for each field, I am posting this because this example would be much more clearer and simple to understand I am believing.

class Student{
    Integer bornYear;
    Integer bornMonth;
    Integer bornDay;
    public Student(int bornYear, int bornMonth, int bornDay) {

        this.bornYear = bornYear;
        this.bornMonth = bornMonth;
        this.bornDay = bornDay;
    }
    public Student(int bornYear, int bornMonth) {

        this.bornYear = bornYear;
        this.bornMonth = bornMonth;

    }
    public Student(int bornYear) {

        this.bornYear = bornYear;

    }
    public Integer getBornYear() {
        return bornYear;
    }
    public void setBornYear(int bornYear) {
        this.bornYear = bornYear;

Had the same error with PHP 7 on XAMPP and OSX.

The above mentioned answer in https://stackoverflow.com/ is good, but it did not completely solve the problem for me. I had to provide the complete certificate chain to make file_get_contents() work again. That's how I did it:

Get root / intermediate certificate

First of all I had to figure out what's the root and the intermediate certificate.

The most convenient way is maybe an online cert-tool like the ssl-shopper

There I found three certificates, one server-certificate and two chain-certificates (one is the root, the other one apparantly the intermediate).

All I need to do is just search the internet for both of them. In my case, this is the root:

thawte DV SSL SHA256 CA

And it leads to his url thawte.com. So I just put this cert into a textfile and did the same for the intermediate. Done.

Get the host certificate

Next thing I had to to is to download my server cert. On Linux or OS X it can be done with openssl:

openssl s_client -showcerts -connect whatsyoururl.de:443 </dev/null 2>/dev/null|openssl x509 -outform PEM > /tmp/whatsyoururl.de.cert

Now bring them all together

Now just merge all of them into one file. (Maybe it's good to just put them into one folder, I just merged them into one file). You can do it like this:

cat /tmp/thawteRoot.crt > /tmp/chain.crt
cat /tmp/thawteIntermediate.crt >> /tmp/chain.crt
cat /tmp/tmp/whatsyoururl.de.cert >> /tmp/chain.crt

tell PHP where to find the chain

There is this handy function openssl_get_cert_locations() that'll tell you, where PHP is looking for cert files. And there is this parameter, that will tell file_get_contents() where to look for cert files. Maybe both ways will work. I preferred the parameter way. (Compared to the solution mentioned above).

So this is now my PHP-Code

$arrContextOptions=array(
    "ssl"=>array(
        "cafile" => "/Applications/XAMPP/xamppfiles/share/openssl/certs/chain.pem",
        "verify_peer"=> true,
        "verify_peer_name"=> true,
    ),
);

$response = file_get_contents($myHttpsURL, 0, stream_context_create($arrContextOptions));

That's all. file_get_contents() is working again. Without CURL and hopefully without security flaws.

The real answer is to use:

Color.parseColor(myPassedColor) in Android, myPassedColor being the hex value like #000 or #000000 or #00000000.

However, this function does not support shorthand hex values such as #000.

put this to applog.sh

#!/bin/sh
PACKAGE=$1
APPPID=`adb -d shell ps | grep "${PACKAGE}" | cut -c10-15 | sed -e 's/ //g'`
adb -d logcat -v long \
 | tr -d '\r' | sed -e '/^\[.*\]/ {N; s/\n/ /}' | grep -v '^$' \
 | grep " ${APPPID}:"

then: applog.sh com.example.my.package

in the view

<form action="/Controller_name/action" method="Post>

 <input type="submit" name="btn1" value="Ok" />
 <input type="submit" name="btn1" value="cancel" />
 <input type="submit" name="btn1" value="Save" />
</form>

in the action

string str =Request.Params["btn1"];
if(str=="ok"){


}
if(str=="cancel"){


}
if(str=="save"){


}

I created these functions based on Joey Guerra's suggestion, thank you for that. I'm elaborating a little bit, perhaps someone can use it. The first function checkDefaults() is called when an input changes, the second is called when the form is submitted using jQuery.post. div.updatesubmit is my submit button, and class 'needsupdate' is an indicator that an update is made but not yet submitted.

function checkDefaults() {
    var changed = false;
        jQuery('input').each(function(){
            if(this.defaultValue != this.value) {
                changed = true;
            }
        });
        if(changed === true) {
            jQuery('div.updatesubmit').addClass("needsupdate");
        } else {
            jQuery('div.updatesubmit').removeClass("needsupdate");
        }
}

function renewDefaults() {
        jQuery('input').each(function(){
            this.defaultValue = this.value;
        });
        jQuery('div.updatesubmit').removeClass("needsupdate");
}

What you could do is create a new class, similar to @Gregoire's example, however, you would want to override the ToString() method so it appears correctly in the combo box e.g.

public class Language
{
    private string _name;
    private string _code;

    public Language(string name, string code)
    {
        _name = name;
        _code = code;
    }

    public string Name { get { return _name; }  }
    public string Code { get { return _code; } }
    public override void ToString()
    {
        return _name;
    }
}

On my end, I used Resource Monitor to see which application was still listening to port 5037 after all the Eclipse and adb restart were unsuccessful for me.

Start > All Programs > Accessories > System Tools >
Resource Monitor > Network > Listening Ports

This eventually showed that java.exe was listening to port 5037, hence, preventing adb from doing so. I killed java.exe, immediately start adb (with adb start-server) and received a confirmation that adb was able to start:

android-sdks\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

In my situation I've been using :uuid fields, and the above answers does not work to my case, because rails 5 are creating a column using :bigint instead :uuid:

add_reference :uploads, :user, index: true, type: :uuid

Reference: Active Record Postgresql UUID

syntax is of objective c is

returnObj = [object functionName: parameters];

Where object is the object which has the method you're calling. If you're calling it from the same object, you'll use 'self'. This tutorial might help you out in learning Obj-C.

In your case it is simply

[self score];

If you want to pass a parameter then it is like that

- (void)score(int x) {
    // some code
}

and I have tried to call it in an other method like this:

- (void)score2 {
    [self score:x];
}

Dummy data (you should supply this for us)

visual1 = data.frame(ISSUE_DATE=runif(100,2006,2008),COUNTED=runif(100,0,50))
visual2 = data.frame(ISSUE_DATE=runif(100,2006,2008),COUNTED=runif(100,0,50))

combine:

visuals = rbind(visual1,visual2)
visuals$vis=c(rep("visual1",100),rep("visual2",100)) # 100 points of each flavour

Now do:

 ggplot(visuals, aes(ISSUE_DATE,COUNTED,group=vis,col=vis)) + 
   geom_point() + geom_smooth()

and adjust colours etc to taste.

Use spread operator and some ES6 here

sys.argv is a attribute of the sys module. It says the arguments passed into the file in the command line. sys.argv[0] catches the directory where the file is located. sys.argv[1] returns the first argument passed in the command line. Think like we have a example.py file.

example.py

import sys # Importing the main sys module to catch the arguments
print(sys.argv[1]) # Printing the first argument

Now here in the command prompt when we do this:

python example.py

It will throw a index error at line 2. Cause there is no argument passed yet. You can see the length of the arguments passed by user using if len(sys.argv) >= 1: # Code. If we run the example.py with passing a argument

python example.py args

It prints:

args

Because it was the first arguement! Let's say we have made it a executable file using PyInstaller. We would do this:

example argumentpassed

It prints:

argumentpassed

It's really helpful when you are making a command in the terminal. First check the length of the arguments. If no arguments passed, do the help text.

DispatchQueue.main.async(execute: {

Serial Queue :

let serial = DispatchQueue(label: "Queuename")

 //Code Here
}

C99 has log2 (as well as log2f and log2l for float and long double).

Nice explanation and example above. I found this (JSON.stringify() array bizarreness with Prototype.js) to complete the answer. Some sites implements its own toJSON with JSONFilters, so delete it.

if(window.Prototype) {
    delete Object.prototype.toJSON;
    delete Array.prototype.toJSON;
    delete Hash.prototype.toJSON;
    delete String.prototype.toJSON;
}

it works fine and the output of the test:

console.log(json);

Result:

"{"a":"test","b":["item","item2","item3"]}"

It allows for further querying further down the line. If this was beyond a service boundary say, then the user of this IQueryable object would be allowed to do more with it.

For instance if you were using lazy loading with nhibernate this might result in graph being loaded when/if needed.

ssize_t is used for functions whose return value could either be a valid size, or a negative value to indicate an error. It is guaranteed to be able to store values at least in the range [-1, SSIZE_MAX] (SSIZE_MAX is system-dependent).

So you should use size_t whenever you mean to return a size in bytes, and ssize_t whenever you would return either a size in bytes or a (negative) error value.

See: http://pubs.opengroup.org/onlinepubs/007908775/xsh/systypes.h.html

import {enableProdMode} from '@angular/core';
enableProdMode();
bootstrap(....);

Right click on "Command prompt" or "PowerShell", in menu click "Run as Administrator" (on Windows XP you can just run it as usual).

As Rick Vanover mentions in See what process is using a TCP port in Windows Server 2008

The following command will show what network traffic is in use at the port level:

Netstat -a -n -o

or

Netstat -a -n -o >%USERPROFILE%\ports.txt

(to open the port and process list in a text editor, where you can search for information you want)

Then,

with the PIDs listed in the netstat output, you can follow up with the Windows Task Manager (taskmgr.exe) or run a script with a specific PID that is using a port from the previous step. You can then use the "tasklist" command with the specific PID that corresponds to a port in question.

Example:

tasklist /svc /FI "PID eq 1348"

My solution is to get keys of an array like below and check that if the key is not integer:

private function is_hash($array) {
    foreach($array as $key => $value) {
        return ! is_int($key);
    }
    return false;
}

It is wrong to get array_keys of a hash array like below:

array_keys(array(
       "abc" => "gfb",
       "bdc" => "dbc"
       )
);

will output:

array(
       0 => "abc",
       1 => "bdc"
)

So, it is not a good idea to compare it with a range of numbers as mentioned in top rated answer. It will always say that it is a hash array if you try to compare keys with a range.

[[]]*3 is not the same as [[], [], []].

It's as if you'd said

a = []
listy = [a, a, a]

In other words, all three list references refer to the same list instance.

If you are trying to completely prevent selecting text by any method as well as on a double click only, you can use the user-select: none css attribute. I have tested in Chrome 68, but according to https://caniuse.com/#search=user-select it should work in the other current normal user browsers.

Behaviorally, in Chrome 68 it is inherited by child elements, and did not allow selecting an element's contained text even if when text surrounding and including the element was selected.

Its super easy to use and you can put it on left, right, top or bottom. Very well documented with sample code and Apache 2.0 license.

It's crucial to understand that the options in a Django model field definition serve (at least) two purposes: defining the database tables, and defining the default format and validation of model forms. (I say "default" because the values can always be overridden by providing a custom form.) Some options affect the database, some options affect forms, and some affect both.

When it comes to null and blank, other answers have already made clear that the former affects the database table definition and the latter affects model validation. I think the distinction can be made even clearer by looking at use cases for all four possible configurations:

• null=False, blank=False: This is the default configuration and means that the value is required in all circumstances.

• null=True, blank=True: This means that the field is optional in all circumstances. (As noted below, though, this is not the recommended way to make string-based fields optional.)

• null=False, blank=True: This means that the form doesn't require a value but the database does. There are a number of use cases for this:

  • The most common use is for optional string-based fields. As noted in the documentation, the Django idiom is to use the empty string to indicate a missing value. If NULL was also allowed you would end up with two different ways to indicate a missing value.

  • Another common situation is that you want to calculate one field automatically based on the value of another (in your save() method, say). You don't want the user to provide the value in a form (hence blank=True), but you do want the database to enforce that a value is always provided (null=False).

  • Another use is when you want to indicate that a ManyToManyField is optional. Because this field is implemented as a separate table rather than a database column, null is meaningless. The value of blank will still affect forms, though, controlling whether or not validation will succeed when there are no relations.

• null=True, blank=False: This means that the form requires a value but the database doesn't. This may be the most infrequently used configuration, but there are some use cases for it:

  • It's perfectly reasonable to require your users to always include a value even if it's not actually required by your business logic. After all, forms are only one way of adding and editing data. You may have code that is generating data which doesn't need the same stringent validation that you want to require of a human editor.

  • Another use case that I've seen is when you have a ForeignKey for which you don't wish to allow cascade deletion. That is, in normal use the relation should always be there (blank=False), but if the thing it points to happens to be deleted, you don't want this object to be deleted too. In that case you can use null=True and on_delete=models.SET_NULL to implement a simple kind of soft deletion.

GROUP BY DATE(date_time_column)

What you can try is writing your code as normal for python using the normal input command. However the trick is to add at the beginning of you program the command input=raw_input.

Now all you have to do is disable (or enable) depending on if you're running in Python/IDLE or Terminal. You do this by simply adding '#' when needed.

Switched off for use in Python/IDLE

    #input=raw_input 

And of course switched on for use in terminal.

    input=raw_input 

I'm not sure if it will always work, but its a possible solution for simple programs or scripts.

Remove an array element based on a key:

Use the unset function like below:

$a = array(
       'salam',
       '10',
       1
);

unset($a[1]);

print_r($a);

/*

    Output:

        Array
        (
            [0] => salam
            [2] => 1
        )

*/

Remove an array element based on value:

Use the array_search function to get an element key and use the above manner to remove an array element like below:

$a = array(
       'salam',
       '10',
       1
);

$key = array_search(10, $a);

if ($key !== false) {
    unset($a[$key]);
}

print_r($a);

/*

    Output:

        Array
        (
            [0] => salam
            [2] => 1
        )

*/

The error says it all, change:

In my case, I was creating the repository from source code already in my pc and that error appeared. I deleted the .git folder and did everything again and it worked :)

When you open catalina.sh / catalina.bat, you can see :

Environment Variable Prequisites

JAVA_HOME Must point at your Java Development Kit installation.

So, set your environment variable JAVA_HOME to point to Java 6. Also make sure JRE_HOME is pointing to the same target, if it is set.

Update: since you are on Windows, see here for how to manage your environment variables

The doxypy input filter allows you to use pretty much all of Doxygen's formatting tags in a standard Python docstring format. I use it to document a large mixed C++ and Python game application framework, and it's working well.

EntityManager.persist() makes an entity persistent whereas EntityManager.flush() actually runs the query on your database.

So, when you call EntityManager.flush(), queries for inserting/updating/deleting associated entities are executed in the database. Any constraint failures (column width, data types, foreign key) will be known at this time.

The concrete behaviour depends on whether flush-mode is AUTO or COMMIT.

This is what you need

In [1]: time.time()
Out[1]: 1347517739.44904

In [2]: time.strftime("%Y-%m-%d %H:%M:%S", time.gmtime(time.time()))
Out[2]: '2012-09-13 06:31:43'

Please input a float instead of an int and that other TypeError should go away.

mend = time.gmtime(float(getbbb_class.end_time)).tm_hour

I've been trying to get this done for a large number of tables during development, and this works as a charm.

DBCC CHECKIDENT('www.newsType', RESEED, 1);
DBCC CHECKIDENT('www.newsType', RESEED);

So, you first force it to be set to 1, then you set it to the highest index of the rows present in the table. Quick and easy rest of the idex.

While Hash#has_key? gets the job done, as Matz notes here, it has been deprecated in favour of Hash#key?.

hash.key?(some_key)

Check this out! This solution solved the problem for me, few simple CSS lines:

.modal:nth-of-type(even) {
z-index: 1042 !important;
}
.modal-backdrop.in:nth-of-type(even) {
    z-index: 1041 !important;
}

Here is a link to where I found it: Bootply Just make sure that the .modual that need to appear on Top is second in HTML code, so CSS can find it as "even".

SELECT 'if object_id(''' + TABLE_NAME + ''') is not null begin drop table "' + TABLE_NAME + '" end;' 
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_NAME LIKE '[prefix]%'

I would use BeginInvoke instead of Invoke as often as possible, unless you are really required to wait until your control has been updated (which in your example is not the case). BeginInvoke posts the delegate on the WinForms message queue and lets the calling code proceed immediately (in your case the for-loop in the SampleFunction). Invoke not only posts the delegate, but also waits until it has been completed.

So in the method AppendTextBox from your example you would replace Invoke with BeginInvoke like that:

public void AppendTextBox(string value)
{
    if (InvokeRequired)
    {
        this.BeginInvoke(new Action<string>(AppendTextBox), new object[] {value});
        return;
    }
    textBox1.Text += value;
}

Well and if you want to get even more fancy, there is also the SynchronizationContext class, which lets you basically do the same as Control.Invoke/Control.BeginInvoke, but with the advantage of not needing a WinForms control reference to be known. Here is a small tutorial on SynchronizationContext.

"ABABAB".replace(/B/g, "A");

As always: don't use regex unless you have to. For a simple string replace, the idiom is:

'ABABAB'.split('B').join('A')

Then you don't have to worry about the quoting issues mentioned in Gracenotes's answer.

I got this error message, because I was migrating an application from SVN to GitHub and it's not enough to invoke a git init in the location of the source code checked out from SVN, but you need to invoke a git svn clone in order to have all the commit history. This way the two source codes on GitHub will have a mutual history and I was able to open pull requests.

Reducing the image size before output results in something that looks sharper, in my case:

convert -density 300 a.pdf -resize 25% a.png

This one works fine for me with apis

import requests

data={'Id':id ,'name': name}
r = requests.post( url = 'https://apiurllink', data = data)

If you want to concatenate the input, then replace printf("%s\n", buffer); with strcat(big_buffer, buffer);. Also create and initialize the big buffer at the beginning: char *big_buffer = new char[BIG_BUFFERSIZE]; big_buffer[0] = '\0';. You should also prevent a buffer overrun by verifying the current buffer length plus the new buffer length does not exceed the limit: if ((strlen(big_buffer) + strlen(buffer)) < BIG_BUFFERSIZE). The modified program would look like this:

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

#define BUFFERSIZE 10
#define BIG_BUFFERSIZE 1024

int main (int argc, char *argv[])
{
    char buffer[BUFFERSIZE];
    char *big_buffer = new char[BIG_BUFFERSIZE];
    big_buffer[0] = '\0';
    printf("Enter a message: \n");
    while(fgets(buffer, BUFFERSIZE , stdin) != NULL)
    {
        if ((strlen(big_buffer) + strlen(buffer)) < BIG_BUFFERSIZE)
        {
            strcat(big_buffer, buffer);
        }
    }
    return 0;
}

Temporary tablespaces are used for database sorting and joining operations and for storing global temporary tables. It may grow in size over a period of time and thus either we need to recreate temporary tablespace or shrink it to release the unused space.

Steps to shrink TEMP Tablespace

If you want search for sensitive data in order to remove it from your git history (which is the reason why I landed here), there are tools for that. Github as a dedicated help page for that issue.

Here is the gist of the article:

The BFG Repo-Cleaner is a faster, simpler alternative to git filter-branch for removing unwanted data. For example, to remove your file with sensitive data and leave your latest commit untouched), run:

bfg --delete-files YOUR-FILE-WITH-SENSITIVE-DATA

To replace all text listed in passwords.txt wherever it can be found in your repository's history, run:

bfg --replace-text passwords.txt

See the BFG Repo-Cleaner's documentation for full usage and download instructions.

INSERT INTO myTable VALUES("First line\r\nSecond line\r\nThird line");

FWIW with Ansible 2.2 one can use include_role:

playbook test.yml:

- name: test
  hosts:
    - 127.0.0.1
  connection: local
  tasks:
    - include_role:
        name: test
        tasks_from: other

then in roles/test/tasks/other.yml:

- name: say something else
  shell: echo "I'm the other guy"

And invoke the playbook with: ansible-playbook test.yml to get:

TASK [test : say something else] *************
changed: [127.0.0.1]

Taking up @ZF007's answer, this is not answering your question as a whole, but can be the solution for the same error. I post it here since I have not found a direct solution as an answer to this error message elsewhere on Stack Overflow.

The error appears when you check whether an array was empty or not.

• if np.array([1,2]): print(1) --> ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all().

• if np.array([1,2])[0]: print(1) --> no ValueError, but: if np.array([])[0]: print(1) --> IndexError: index 0 is out of bounds for axis 0 with size 0.

• if np.array([1]): print(1) --> no ValueError, but again will not help at an array with many elements.

• if np.array([]): print(1) --> DeprecationWarning: The truth value of an empty array is ambiguous. Returning False, but in future this will result in an error. Use 'array.size > 0' to check that an array is not empty.

Doing so:

• if np.array([]).size: print(1) solved the error.

I think you should be able to select a disabled button using the following:

button[disabled=disabled], button:disabled {
    // your css rules
}

The default location to put all the web projects in ubuntu with LAMPP is :

 /var/www/

You may make symbolic link to public_html directory from this directory.Refered. Hope this is helpful.

To select and element where you know only the attribute value you can use the below jQuery script

var src = $('.conversation_img[alt="example"]').attr('src');

Please refer the jQuery Documentation for attribute equals selectors

Please also refer to the example in Demo

Following is the code incase you are not able to access the demo..

HTML

<div>
    <img alt="example" src="\images\show.jpg" />
    <img  alt="exampleAll" src="\images\showAll.jpg" />  

</div>

SCRIPT JQUERY

var src = $('img[alt="example"]').attr('src');
alert("source of image with alternate text = example - " + src);


var srcAll = $('img[alt="exampleAll"]').attr('src');
alert("source of image with alternate text = exampleAll - " + srcAll );

Output will be

Two Alert messages each having values

1. source of image with alternate text = example - \images\show.jpg
2. source of image with alternate text = exampleAll - \images\showAll.jpg

I'm going to answer my own question.

1. innerJoin should use the keyword "WITH" instead of "ON" (Doctrine's documentation [13.2.6. Helper methods] is inaccurate; [13.2.5. The Expr class] is correct)
2. no need to link foreign keys in join condition as they're already specified in the entity mapping.

Therefore, the following works for me

$qb->select('c')
    ->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
    ->where('c.username = :username');

or

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
    ->where('c.username = :username');

If you don't mention the random_state in the code, then whenever you execute your code a new random value is generated and the train and test datasets would have different values each time.

However, if you use a particular value for random_state(random_state = 1 or any other value) everytime the result will be same,i.e, same values in train and test datasets. Refer below code:

import pandas as pd 
from sklearn.model_selection import train_test_split
test_series = pd.Series(range(100))
size30split = train_test_split(test_series,random_state = 1,test_size = .3)
size25split = train_test_split(test_series,random_state = 1,test_size = .25)
common = [element for element in size25split[0] if element in size30split[0]]
print(len(common))

Doesn't matter how many times you run the code, the output will be 70.

70

Try to remove the random_state and run the code.

import pandas as pd 
from sklearn.model_selection import train_test_split
test_series = pd.Series(range(100))
size30split = train_test_split(test_series,test_size = .3)
size25split = train_test_split(test_series,test_size = .25)
common = [element for element in size25split[0] if element in size30split[0]]
print(len(common))

Now here output will be different each time you execute the code.

Try this

let path = "/{id}/{name}/{age}";
const paramsPattern = /[^{\}]+(?=})/g;
let extractParams = path.match(paramsPattern);
console.log("extractParams", extractParams) // prints all the names between {} = ["id", "name", "age"]

        }
    };

    // option 1
    Integer[] array = new Integer[] { 1, 24, 4, 4, 345 };
    Arrays.sort(array, comparator);

    // option 2
    int[] array2 = new int[] { 1, 24, 4, 4, 345 };
    List<Integer>list = Ints.asList(array2);
    Collections.sort(list, comparator);
    array2 = Ints.toArray(list);

For Visual Studio 2013 you need to remove that folder from this path:

%AppData%\..\Local\Microsoft\VisualStudio\12.0

A general tip , if you get confused by any of new JS syntax and how it will compile , you can check babel. For example copying your code in babel and selecting the es2015 preset will give an output like this

handleChange = function handleChange(field) {
 return function (e) {
 e.preventDefault();
  // Do something here
   };
 };

If your matrix is given in row manner like below, where size is s*s here s=5 5 31 100 65 12 18 10 13 47 157 6 100 113 174 11 33 88 124 41 20 140 99 32 111 41 20

then you can use this

s=int(input())
b=list(map(int,input().split()))
arr=[[b[j+s*i] for j in range(s)]for i in range(s)]

your matrix will be 'arr'

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

Background = new SolidColorBrush(Colors.Red);

Look into BufferedReader. If that isn't general/high-level enough, I recommend reading the I/O tutorial.

I believe that C++ is the language that you are looking for. The majority of game development is in C++ because it is a multi-paradigm language (OOP, meta-programming, etc.) and because it allows memory management. What makes C++ even better is that it can be used to develop on a multitude of platforms whereas C# cannot do so on such a big scale.

Many will say that with C# you will not have to worry about memory allocation and this is true at a certain price. You will have the burden of the .NET framework on your shoulders and will slowly see the limitations of C# in the way certain tasks must be done.

Probably you have read from some answers that C++ is a hard programming language. This is mostly true, but perhaps you haven't heard about C++0x. Some features found in C# such as garbage collection will become available (optional for you to use) with C++0x. Also, multi-threading will finally be supported by the language with this revision of the C++ standard.

I would recommend that you buy a few C++ books as well as C++ DirectX/OpenGL books.

Firstly you have to create state in app.js as below

.state('login', {
      url: '/',
      templateUrl: 'views/login.html',
      controller: 'LoginCtrl'
    })

and use below code in controller

 $location.path('login'); 

Hope this will help you

function listAllItems(){  
    for (i=0; i<localStorage.length; i++)  
    {  
        key = localStorage.key(i);  
        alert(localStorage.getItem(key));
    }  
}

select() is a bit too low-level for convenience. I suggest you use the ncurses library to put the terminal in cbreak mode and delay mode, then call getch(), which will return ERR if no character is ready:

WINDOW *w = initscr();
cbreak();
nodelay(w, TRUE);

At that point you can call getch without blocking.

Though you have solved the problem, I just post the reason here for some others with the similar problem.

The reason is there's an space in your path(directory name VirtualBox VMs) which will separate the command. So the error appears.

Here is a good tutorial for launching application from within another app:
iOS SDK: Working with URL Schemes
And, it is not possible to launch arbitrary application, but the native applications which registered the URL Schemes.

The correct answer is this (example version):

• In parent pom.xml you should have (not inside properties):

  <version>0.0.1-SNAPSHOT</version>
  

• In all child modules you should have:

  <parent>
      <groupId>com.vvirlan</groupId>
      <artifactId>grafiti</artifactId>
      <version>0.0.1-SNAPSHOT</version>
  </parent>
  

So it is hardcoded.

Now, to update the version you do this:

mvn versions:set -DnewVersion=0.0.2-SNAPSHOT
mvn versions:commit # Necessary to remove the backup file pom.xml

and all your 400 modules will have the parent version updated.

For spring :

File inputFile = new ClassPathResource("\\chrome\\chromedriver.exe").getFile();
System.setProperty("webdriver.chrome.driver",inputFile.getCanonicalPath());

Not that anyone would ever have CAPS on when entering a password...but it can give this error.

you just add the path of .pdb to work directory of VS!

As of conda 4.4, the command

conda activate <envname>

is the same on all platforms. The procedure to add conda to the PATH environment variable for non-Windows platforms (on Windows you should use the Anaconda Prompt), as well as the change in environment activation procedure, is detailed in the release notes for conda 4.4.0.

For conda versions older than 4.4, command is either

source activate <envname>

on Linux and macOS or

activate <envname>

on Windows. You need to remove the conda.

It would be more correct to say that stdin, stdout, and stderr are "I/O streams" rather than files. As you've noticed, these entities do not live in the filesystem. But the Unix philosophy, as far as I/O is concerned, is "everything is a file". In practice, that really means that you can use the same library functions and interfaces (printf, scanf, read, write, select, etc.) without worrying about whether the I/O stream is connected to a keyboard, a disk file, a socket, a pipe, or some other I/O abstraction.

Most programs need to read input, write output, and log errors, so stdin, stdout, and stderr are predefined for you, as a programming convenience. This is only a convention, and is not enforced by the operating system.

<div id='element_123_wrapper_text'>My sample DIV</div>

The Operator ^ - Match elements that starts with given value

div[id^="element_123"] {

}

The Operator $ - Match elements that ends with given value

div[id$="wrapper_text"] {

}

The Operator * - Match elements that have an attribute containing a given value

div[id*="wrapper_text"] {

}

You can use if(addr && (addr = $.trim(addr)))

This has the advantage of actually removing any outer whitespace from addr instead of just ignoring it when performing the check.

For example, I get date/time in format Spanish.

$('#timePicker').datetimepicker({
    defaultDate: new Date(),
    format:'DD/MM/YYYY HH:mm'
});

This method works for Excel 2016, and calculates on cell value, so can be used on formula arrays (i.e. it will ignore blank cells that contain a formula).

• Highlight the range.
• Home > Conditional Formatting > New Rule > Use a Formula.
• Enter "=LEN(#)>0" (where '#' is the upper-left-most cell in your range).
• Alter the formatting to suit your preference.

Note: Len(#)>0 be altered to only select cell values above a certain length.

Note 2: '#' must not be an absolute reference (i.e. shouldn't contain '$').

The most compatible way of doing this is using tput to discover the right sequences to send to the terminal:

bold=$(tput bold)
normal=$(tput sgr0)

then you can use the variables $bold and $normal to format things:

echo "this is ${bold}bold${normal} but this isn't"

gives

                            .min( Comparator.comparing( LocalDate::toEpochDay ) )
                            .get();

To avoid this warning, instead of using:

parseInt("999", 10);

You may replace it by:

Number("999");

^{Note that parseInt and Number have different behaviors, but in some cases, one can replace the other.}

The documentation for templating is partial, I watched the source.

The _.template function has 3 arguments:

1. String text : the template string
2. Object data : the evaluation data
3. Object settings : local settings, the _.templateSettings is the global settings object

If no data (or null) given, than a render function will be returned. It has 1 argument:

1. Object data : same as the data above

There are 3 regex patterns and 1 static parameter in the settings:

1. RegExp evaluate : "<%code%>" in template string
2. RegExp interpolate : "<%=code%>" in template string
3. RegExp escape : "<%-code%>"
4. String variable : optional, the name of the data parameter in the template string

The code in an evaluate section will be simply evaluated. You can add string from this section with the __p+="mystring" command to the evaluated template, but this is not recommended (not part of the templating interface), use the interpolate section instead of that. This type of section is for adding blocks like if or for to the template.

The result of the code in the interpolate section will added to the evaluated template. If null given back, then empty string will added.

The escape section escapes html with _.escape on the return value of the given code. So its similar than an _.escape(code) in an interpolate section, but it escapes with \ the whitespace characters like \n before it passes the code to the _.escape. I don't know why is that important, it's in the code, but it works well with the interpolate and _.escape - which doesn't escape the white-space characters - too.

By default the data parameter is passed by a with(data){...} statement, but this kind of evaluating is much slower than the evaluating with named variable. So naming the data with the variable parameter is something good...

For example:

var html = _.template(
    "<pre>The \"<% __p+=_.escape(o.text) %>\" is the same<br />" +
        "as the  \"<%= _.escape(o.text) %>\" and the same<br />" +
        "as the \"<%- o.text %>\"</pre>",
    {
        text: "<b>some text</b> and \n it's a line break"
    },
    {
        variable: "o"
    }
);

$("body").html(html);

results

The "<b>some text</b> and 
 it's a line break" is the same
as the "<b>some text</b> and 
 it's a line break" and the same
as the "<b>some text</b> and 
 it's a line break"

You can find here more examples how to use the template and override the default settings: http://underscorejs.org/#template

By template loading you have many options, but at the end you always have to convert the template into string. You can give it as normal string like the example above, or you can load it from a script tag, and use the .html() function of jquery, or you can load it from a separate file with the tpl plugin of require.js.

Another option to build the dom tree with laconic instead of templating.

From your example, it seems to me you want to use a static method.

class mystuff:
  @staticmethod
  def average(a,b,c): #get the average of three numbers
    result=a+b+c
    result=result/3
    return result

print mystuff.average(9,18,27)

Please note that an heavy usage of static methods in python is usually a symptom of some bad smell - if you really need functions, then declare them directly on module level.

For your first question, find the position of some value in a list x using index(), like so:

x.index(value)

For your second question, to check for multiple same values you should split your list into chunks and use the same logic from above. They say divide and conquer. It works. Try this:

value = 1 
x = [1,2,3,4,5,6,2,1,4,5,6]

chunk_a = x[:int(len(x)/2)] # get the first half of x 
chunk_b = x[int(len(x)/2):] # get the rest half of x

print(chunk_a.index(value))
print(chunk_b.index(value))

Hope that helps!

Well there is a more easy way to do this

drawerToggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.open_drawer, R.string.close_drawer);
arrow = drawerToggle.getDrawerArrowDrawable();

And then

arrow.setColor(getResources().getColor(R.color.blue);

for(j = 0; j<=90; j = j+3)
{

}

j+3 will not assign the new value to j, add j=j+3 will assign the new value to j and the loop will move up by 3.

j++ is like saying j = j+1, so in that case your assigning the new value to j just like the one above.

Note: Do not do this in production code, use http instead, or the actual self signed public key as suggested above.

On HttpClient 4.xx:

public class HttpClientTrustingAllCertsTest {

    @Test
    public void shouldAcceptUnsafeCerts() throws Exception {
        DefaultHttpClient httpclient = httpClientTrustingAllSSLCerts();

    }

        } };
        return trustAllCerts;

}

You can use the bootstrap grid system. as Yoann said

 <div class="container">
    <div class="row">
        <form role="form">
           <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputEmail1">Email address</label>
                        <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
                    </div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputEmail1">Name</label>
                        <input type="text" class="form-control" id="exampleInputEmail1" placeholder="Enter Name">
                    </div>
                    <div class="clearfix"></div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputPassword1">Password</label>
                        <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
                    </div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputPassword1">Confirm Password</label>
                        <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Confirm Password">
                    </div>
          </form>
         <div class="clearfix">
      </div>
    </div>
</div>

If you're using jQuery 1.5, then statusCode will work.

If you're using jQuery 1.4, try this:

error: function(jqXHR, textStatus, errorThrown) {
    alert(jqXHR.status);
    alert(textStatus);
    alert(errorThrown);
}

You should see the status code from the first alert.

You don't need to replace it with anything. The setting magic_quotes_runtime is removed in PHP6 so the function call is unneeded. If you want to maintain backwards compatibility it may be wise to wrap it in a if statement checking phpversion using version_compare

You don't need to set the value at all. ng-model takes care of it all:

• set the input value from the model
• update the model value when you change the input
• update the input value when you change the model from js

Here's the fiddle for this: http://jsfiddle.net/terebentina/9mFpp/
