I found the solution to this. There is a temporary tablespace called TEMP which is used internally by database for operations like distinct, joins,etc. Since my query(which has 4 joins) fetches almost 50 million records the TEMP tablespace does not have that much space to occupy all data. Hence the query fails even though my tablespace has free space.So, after increasing the size of TEMP tablespace the issue was resolved. Hope this helps someone with the same issue. Thanks :)

This is a good example of the maven-ear-plugin part.

You can also check the maven archetypes that are available as an example. If you just runt mvn archetype:generate you'll get a list of available archetypes. One of them is

maven-archetype-j2ee-simple

import re

htmlString = '</dd><dt> Fine, thank you.&#160;</dt><dd> Molt bé, gràcies. (<i>mohl behh, GRAH-syuhs</i>)'

SearchStr = '(\<\/dd\>\<dt\>)+ ([\w+\,\.\s]+)([\&\#\d\;]+)(\<\/dt\>\<dd\>)+ ([\w\,\s\w\s\w\?\!\.]+) (\(\<i\>)([\w\s\,\-]+)(\<\/i\>\))'

Result = re.search(SearchStr.decode('utf-8'), htmlString.decode('utf-8'), re.I | re.U)

print Result.groups()

Works that way. The expression contains non-latin characters, so it usually fails. You've got to decode into Unicode and use re.U (Unicode) flag.

I'm a beginner too and I faced that issue a couple of times myself.

I came across several answers in SO and at the end I realized that my error was that I had misspelled "Html.TextBoxFor." In my case what I wrote was "Html.TextboxFor." I did not uppercase the B in TextBoxFor. Fixed that and voilà. Problem solved. I hope this helps someone.

Try like

var hasName = 'N';
if (name == "true") {
    hasName = 'Y';
}

Or even try with ternary operator like

var hasName = (name == "true") ? "Y" : "N" ;

Even simply you can try like

var hasName = (name) ? "Y" : "N" ;

Since name has either Yes or No but iam not sure with it.

In case anyone else looking for additional "enter" keypress support, here's an update to the fiddle provided by Gloppy

Code for keypress binding:

elm.bind("keydown keypress", function(event) {
    if (event.which === 13) {
        scope.$apply(function() {
            ngModelCtrl.$setViewValue(elm.val());
        });
    }
});

The standard way to do this sort of thing is to use external tools. Disallowing the use of external tools while writing a shell script is absurd. However, if you really don't want to use external tools, you can print line 5 with:

i=0; while read line; do test $((++i)) = 5 && echo "$line"; done < input-file

Note that this will print logical line 5. That is, if input-file contains line continuations, they will be counted as a single line. You can change this behavior by adding -r to the read command. (Which is probably the desired behavior.)

As it allows to install more than one version of java, I had install many 3 versions unknowingly but it was point to latest version "11.0.2"

I could able to solve this issue with below steps to move to "1.8"

Very late answer but I think this is the best answer of this topic. Hope this is useful.

You can get user info when a request is made with the url below:

https://www.instagram.com/{username}/?__a=1

E.g:

This url will get all information about a user whose username is therock

https://www.instagram.com/therock/?__a=1

Update i June-20-2019, the API is public now. No authentication required.

Update in December-11-2018, I needed to confirm that this endpoint still work. You need to login before sending request to this site because it's not public endpoint anymore. The login step is easy also. This is my demo: https://youtu.be/ec5QhwM6fvc

Update in Apr-17-2018, it's look like this endpoint still working (but its not public endpoint anymore), you must send a request with extra information to that endpoint. (Press F12 to open developer toolbar, then click to Network Tab and trace the request.)

Sorry because I'm too busy. Hope this information help you guys. Hmm, feel free to give me a down-vote if you want.

Update in Apr-12-2018, cameronjonesweb said that this endpoint doesn't work anymore. When he/she trying to access this endpoint, 403 status code return.

To tell the truth...you have to make the decision as to which is the better language. I know what I can do with C#. I know what can be done in C++. C# isn't made to do what C++ was made to do...write code at the most basic level and still be somewhat meaningful when read by human eyes.

We are developing a game engine with C#, DirectX...is it a challenge? hell yeah...but it's something we chose to do. We are looking at some performance levels that are very close to what C++ can give. So, I see no problems with this effort.

To cross-platform development, if it weren't for .Net, we might not have the Mono platform. The Mono platform has broadened our platform base.

Here is some support to my arguments...

This method is recommended

<link rel="icon" 
  type="image/png" 
  href="/somewhere/myicon.png" />

Another way of using SQLite database in NET Framework is to use Fluent-NHibernate.
[It is NET module which wraps around NHibernate (ORM module - Object Relational Mapping) and allows to configure NHibernate programmatically (without XML files) with the fluent pattern.]

Here is the brief 'Getting started' description how to do this in C# step by step:

https://github.com/jagregory/fluent-nhibernate/wiki/Getting-started

It includes a source code as an Visual Studio project.

In my case, I used a callback in yaxis ticks, my values are in percent and when it reaches 100% it doesn't show the dot, I used this :

      yAxes: [{
                   ticks: {
                       beginAtZero: true,
                       steps: 10,
                       stepValue: 5,
                       min: 0,
                       max: 100.1,
                       callback: function(value, index, values) {
                           if (value !== 100.1) {
                               return values[index]
                           }
                       }
                   }
               }],

And it worked well.

You could use a semaphore.

While the condition is not met, another thread acquires the semaphore.
Your thread would try to acquire it with acquireUninterruptibly()
or tryAcquire(int permits, long timeout, TimeUnit unit) and would be blocked.

When the condition is met, the semaphore is also released and your thread would acquire it.

You could also try using a SynchronousQueue or a CountDownLatch.

You just have to use class="row-eq-height" with your class="row" to get equal height columns for previous bootstrap versions.

but with bootstrap 4 this comes natively.

Here JQuery plugin version of Maryan solution with handle optimization. Only with JQuery 1.7+!

(function ($) {
    $.fn.heartbeat = function (options) {
        var settings = $.extend({
            // These are the defaults.
            events: 'mousemove keydown'
            , url: '/Home/KeepSessionAlive'
            , every: 5*60*1000
        }, options);

        var keepSessionAlive = false
         , $container = $(this)
         , handler = function () {
             keepSessionAlive = true;
             $container.off(settings.events, handler)
         }, reset = function () {
             keepSessionAlive = false;
             $container.on(settings.events, handler);
             setTimeout(sessionAlive, settings.every);
         }, sessionAlive = function () {
             keepSessionAlive && $.ajax({
                 type: "POST"
                 , url: settings.url
                 ,success: reset
                });
         };
        reset();

        return this;
    }
})(jQuery)

and how it does import in your *.cshtml

$('body').heartbeat(); // Simple
$('body').heartbeat({url:'@Url.Action("Home", "heartbeat")'}); // different url
$('body').heartbeat({every:6*60*1000}); // different timeout

This is what the standard has to say about operator==

21.4.8.2 operator==

template<class charT, class traits, class Allocator>
bool operator==(const basic_string<charT,traits,Allocator>& lhs,
                const basic_string<charT,traits,Allocator>& rhs) noexcept;

Returns: lhs.compare(rhs) == 0.

Seems like there isn't much of a difference!

Try adding the following runtime assembly bindings:

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

This error message comes specifically from the XDebug extension. PHP itself does not have a function nesting limit. Change the setting in your php.ini:

xdebug.max_nesting_level = 200

or in your PHP code:

ini_set('xdebug.max_nesting_level', 200);

As for if you really need to change it (i.e.: if there's a alternative solution to a recursive function), I can't tell without the code.

Jan 2020 Update

@Flimm has explained all the differences very well. Generally, we want to know the difference between all tools because we want to decide what's best for us. So, the next question would be: which one to use? I suggest you choose one of the two official ways to manage virtual environments:

• Python Packaging now recommends Pipenv
• Python.org now recommends venv

A quick fix where nothing else works:

const a.b = 5 // error

const a['b'] = 5 // error if ts-lint rule no-string-literal is enabled

const B = 'b'
const a[B] = 5 // always works

Not good practice but provides a solution without needing to turn off no-string-literal

I normally use the circular-json npm package to solve this.

// Felix Kling's example
var a = {};
a.b = a;
// load circular-json module
var CircularJSON = require('circular-json');
console.log(CircularJSON.stringify(a));
//result
{"b":"~"}

Note: circular-json has been deprecated, I now use flatted (from the creator of CircularJSON):

// ESM
import {parse, stringify} from 'flatted/esm';

// CJS
const {parse, stringify} = require('flatted/cjs');

const a = [{}];
a[0].a = a;
a.push(a);

stringify(a); // [["1","0"],{"a":"0"}]

While loop syntax example in MySQL:

delimiter //

CREATE procedure yourdatabase.while_example()
wholeblock:BEGIN
  declare str VARCHAR(255) default '';
  declare x INT default 0;
  SET x = 1;

  WHILE x <= 5 DO
    SET str = CONCAT(str,x,',');
    SET x = x + 1;
  END WHILE;

  select str;
END//

Which prints:

mysql> call while_example();
+------------+
| str        |

  REPEAT
    SET str = CONCAT(str,x,',');
    SET x = x - 1;
    UNTIL x <= 0
  END REPEAT;

  SELECT str;

Do the tutorial: http://www.mysqltutorial.org/stored-procedures-loop.aspx

If I catch you pushing this kind of MySQL for-loop constructs into production, I'm going to shoot you with the foam missile launcher. You can use a pipe wrench to bang in a nail, but doing so makes you look silly.

Here's some background on the mechanism you should use, called Package Configurations: Understanding Integration Services Package Configurations. The article describes 5 types of configurations:

• XML configuration file
• Environment variable
• Registry entry
• Parent package variable
• SQL Server

Here's a walkthrough of setting up a configuration on a Connection Manager: SQL Server Integration Services SSIS Package Configuration - I do realize this is using an environment variable for the connection string (not a great idea), but the basics are identical to using an XML file. The only step(s) you have to change in that walkthrough are the configuration type, and then a path.

$(document).on('input','#mytxtBox',function () { 
 console.log($('#mytxtBox').val());
});

You can use 'input' event to detect the content change in the textbox. Don't use 'live' to bind the event as it is deprecated in Jquery-1.7, So make use of 'on'.

I found that if you just want to change the height of the element the image takes up, this will be the code that will help

.carousel-item { height: 600px !important; }

however, this won't make the size of the image dynamic, it will simply crop the image to its size.

You can check your all defined function by

$arr = get_defined_functions();
print_r($arr);

this will give you array of all functions in if your function exist in it you can use it like:

 {{ user.myfunction({{parameter}}) }}

You can query the actual number of rows with

SELECT Count(*) FROM tblName

There are changes in mongod.conf file in the latest MongoDB v 3.6.5 +

Here is how I fixed this issue on mac os High Sierra v 10.12.3

Note: I assume that you have installed/upgrade MongoDB using homebrew

mongo --version

MongoDB shell version v3.6.5 
git version: a20ecd3e3a174162052ff99913bc2ca9a839d618 
OpenSSL version: OpenSSL 1.0.2o  27 Mar 2018 
allocator: system modules: none build environment:
distarch: x86_64
target_arch: x86_64

1. find mongod.conf file

    sudo find / -name mongod.conf` 
   

   /usr/local/etc/mongod.conf > first result .

2. open mongod.conf file

   sudo vi /usr/local/etc/mongod.conf
   

3. edit in the file for remote access under net: section

    port: 27017  
    bindIpAll: true 
    #bindIp: 127.0.0.1 // comment this out
   

4. restart mongodb

   if you have installed using brew than

   brew services stop mongodb
   
   brew services start mongodb
   

otherwise, kill the process.

   sudo kill -9 <procssID>

val() returns the value of the <select> element, i.e. the value attribute of the selected <option> element.

Since you actually want the inner text of the selected <option> element, you should match that element and use text() instead:

var nationality = $("#dancerCountry option:selected").text();

Use the string.substring(from, to) API. In your case, use string.substring(0,8).

WORKAROUND:

The possible workaround is modify your project's platform from 'Any CPU' to 'X86' (in Project's Properties, Build/Platform's Target)

ROOTCAUSE

The VSS Interop is a managed assembly using 32-bit Framework and the dll contains a 32-bit COM object. If you run this COM dll in 64 bit environment, you will get the error message.

Here, I summarize a few ways which may return different results to your question, so be careful:

# First assign your "id"s to an R object.
# Here's a hypothetical example:
id <- c("a","b","b","c","c","c","d","d","d","d")

#To return ALL MINUS ONE duplicated values:
id[duplicated(id)]
## [1] "b" "c" "c" "d" "d" "d"

#To return ALL duplicated values by specifying fromLast argument:
id[duplicated(id) | duplicated(id, fromLast=TRUE)]
## [1] "b" "b" "c" "c" "c" "d" "d" "d" "d"

#Yet another way to return ALL duplicated values, using %in% operator:
id[ id %in% id[duplicated(id)] ]
## [1] "b" "b" "c" "c" "c" "d" "d" "d" "d"

Hope these help. Good luck.

If you are using Spyder in the Anaconda package...

In the IPython Console, use

!conda install packageName

This works locally too.

!conda install /path/to/package.tar

Note: the ! is required when using IPython console from within Spyder.

class B is only declared but not defined at the beginning, which is what the compiler complains about. The root cause is that in class A's Call Function, you are referencing instance b of type B, which is incomplete and undefined. You can modify source like this without introducing new file(just for sake of simplicity, not recommended in practice):

using namespace std;

class A 
{
public:

    void CallFunction ();
};

class B: public A
{
public:
    virtual void bFunction()
    {
        //stuff done here
    }
};


 // postpone definition of CallFunction here

 void A::CallFunction ()
 {
     B b;
     b.bFunction();
 }

In my opinion iosSlider is amazing. It works in almost any device and it is well documented. It's free for personal usage, but for commercial sites license costs $20.

Also a great option is touchCarousel or RoyalSlider from same author. These two have everything you'll need, but also not free and have a price of $10-12

The best code is no code at all:

The fundamental nature of coding is that our task, as programmers, is to recognize that every decision we make is a trade-off. […] Start with brevity. Increase the other dimensions as required by testing.

Consequently, less code is better code: Prefer "" to string.Empty or String.Empty. Those two are six times longer with no added benefit — certainly no added clarity, as they express the exact same information.

Try this:

Create a model called Profile and reference the user with a OneToOneField and provide an option of related_name.

models.py

from django.db import models
from django.contrib.auth.models import *
from django.dispatch import receiver
from django.db.models.signals import post_save

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='user_profile')

    def __str__(self):
        return self.user.username

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    try:
        if created:
            Profile.objects.create(user=instance).save()
    except Exception as err:
        print('Error creating user profile!')

Now to directly access the profile using a User object you can use the related_name.

views.py

from django.http import HttpResponse

def home(request):
    profile = f'profile of {request.user.user_profile}'
    return HttpResponse(profile)

The stopPropagation() method stops the bubbling of an event to parent elements, preventing any parent handlers from being notified of the event.

You can use the method event.isPropagationStopped() to know whether this method was ever called (on that event object).

Syntax:

Here is the simple syntax to use this method:

event.stopPropagation() 

Example:

$("div").click(function(event) {
    alert("This is : " + $(this).prop('id'));

    // Comment the following to see the difference
    event.stopPropagation();
});?

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

I got this to work by clearing the file input value onClick and then posting the file onChange. This allows the user to select the same file twice in a row and still have the change event fire to post to the server. My example uses the the jQuery form plugin.

$('input[type=file]').click(function(){
    $(this).attr("value", "");
})  
$('input[type=file]').change(function(){
    $('#my-form').ajaxSubmit(options);      
})

Use fileReader.readAsDataURL( fileObject ), this will encode it to base64, which you can safely upload to your server.

In this answer there is also the best answer I found to your question:

HTML table with fixed headers?

and based on pure CSS.

You can also use a relative path in your docker-compose.yml file like this (tested on Windows host, Linux container):

volumes:
    - ./test.conf:/fluentd/etc/test.conf

Al WebApi 2, just calling HttpContext.Current.Request.Path;

Okay, first a few terms slightly oversimplified.

In git, a tag (like many other things) is what's called a treeish. It's a way of referring to a point in in the history of the project. Treeishes can be a tag, a commit, a date specifier, an ordinal specifier or many other things.

Now a branch is just like a tag but is movable. When you are "on" a branch and make a commit, the branch is moved to the new commit you made indicating it's current position.

Your HEAD is pointer to a branch which is considered "current". Usually when you clone a repository, HEAD will point to master which in turn will point to a commit. When you then do something like git checkout experimental, you switch the HEAD to point to the experimental branch which might point to a different commit.

Now the explanation.

When you do a git checkout v2.0, you are switching to a commit that is not pointed to by a branch. The HEAD is now "detached" and not pointing to a branch. If you decide to make a commit now (as you may), there's no branch pointer to update to track this commit. Switching back to another commit will make you lose this new commit you've made. That's what the message is telling you.

Usually, what you can do is to say git checkout -b v2.0-fixes v2.0. This will create a new branch pointer at the commit pointed to by the treeish v2.0 (a tag in this case) and then shift your HEAD to point to that. Now, if you make commits, it will be possible to track them (using the v2.0-fixes branch) and you can work like you usually would. There's nothing "wrong" with what you've done especially if you just want to take a look at the v2.0 code. If however, you want to make any alterations there which you want to track, you'll need a branch.

You should spend some time understanding the whole DAG model of git. It's surprisingly simple and makes all the commands quite clear.

You could also use a LEFT JOIN and IS NULL condition:

SELECT 
  mac, 
  creation_date 
FROM 
  logs
    LEFT JOIN consols ON logs.mac = consols.mac
WHERE 
  logs_type_id=11
AND
  consols.mac IS NULL;

An index on the "mac" columns might improve performance.

getResource() was working fine with the resources files placed in src/main/resources only. To get a file which is at the path other than src/main/resources say src/test/java you need to create it exlicitly.

the following example may help you

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.net.URISyntaxException;
import java.net.URL;

public class Main {
    public static void main(String[] args) throws URISyntaxException, IOException {
        URL location = Main.class.getProtectionDomain().getCodeSource().getLocation();
        BufferedReader br = new BufferedReader(new FileReader(location.getPath().toString().replace("/target/classes/", "/src/test/java/youfilename.txt")));
    }
}

Maybe useful for anyone else running into this issue: When setting the port on the properties:

props.put("mail.smtp.port", smtpPort);

..make sure to use a string object. Using a numeric (ie Long) object will cause this statement to seemingly have no effect.

You can also use;

 List<KeyValuePair<string, string>> Mappings;

Node.js doesn't use threading. According to its inventor that's a key feature. At the time of its invention, threads were slow, problematic, and difficult. Node.js was created as the result of an investigation into an efficient single-core alternative. Most Node.js enthusiasts still cite ye olde argument as if threads haven't been improved over the past 50 years.

As you know, Node.js is used to run JavaScript. The JavaScript language has also developed over the years. It now has ways of using multiple cores - i.e. what Threads do. So, via advancements in JavaScript, you can do some multi-core multi-tasking in your applications. user158 points out that Node.js is playing with it a bit. I don't know anything about that. But why wait for Node.js to approve of what JavaScript has to offer.

Google for JavaScript multi-threading instead of Node.js multi-threading. You'll find out about Web Workers, Promises, and other things.

I've read that using document fragments is performant because it avoids page reflow upon each insertion of DOM element, it's also well supported by all browsers (even IE 6).

var fragment = document.createDocumentFragment();_x000D_
_x000D_
$.each(result, function() {_x000D_
  fragment.appendChild($("<option />").val(this.ImageFolderID).text(this.Name)[0]);_x000D_
});_x000D_
_x000D_
$("#options").append(fragment);

I first read about this in CodeSchool's JavaScript Best Practices course.

Here's a comparison of different approaches, thanks go to the author.

#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
    std::string input = "abc,def,   ghi";
    std::istringstream ss(input);
    std::string token;
    size_t pos=-1;
    while(ss>>token) {
      while ((pos=token.rfind(',')) != std::string::npos) {
        token.erase(pos, 1);
      }
      std::cout << token << '\n';
    }
}

You can also do it one line:

int hello = Integer.parseInt(((Button)findViewById(R.id.button1)).getText().toString().replaceAll("[\\D]", ""));

Reading from order of execution

1. grab the view using findViewById(R.id.button1)
2. use ((Button)______) to cast the View as a Button
3. Call .GetText() to get the text entry from Button
4. Call .toString() to convert the Character Varying to a String
5. Call .ReplaceAll() with "[\\D]" to replace all Non Digit Characters with "" (nothing)
6. Call Integer.parseInt() grab and return an integer out of the Digit-only string.

Thanks @Arnaud & @Conny for highlighting this answer. This really helped me. I would like to add one more thing here is, adding this line <meta http-equiv="x-ua-compatible" content="IE=edge"> just after the title in tag prior to all meta tags is must for to work as it overrides the compatibility mode of IE.

The problem with using querySelectorAll and a for loop is that it creates a whole new event handler for each element in the array.

Sometimes that is exactly what you want. But if you have many elements, it may be more efficient to create a single event handler and attach it to a container element. You can then use event.target to refer to the specific element which triggered the event:

document.body.addEventListener("click", function (event) {
  if (event.target.classList.contains("delete")) {
    var title = event.target.getAttribute("title");

    if (!confirm("sure u want to delete " + title)) {
      event.preventDefault();
    }
  }
});

In this example we only create one event handler which is attached to the body element. Whenever an element inside the body is clicked, the click event bubbles up to our event handler.

It seems to work fine in Postgresql 9.5:

SELECT current_setting('TIMEZONE');

I use the environment variable CDPATH

It seems like there is just a simple typo error:

1. Remove the semicolon after change(), there should not be any in the function declaration.
2. Add a quote in front of the myButton1 declaration.

Corrected code:

<input onclick="change()" type="button" value="Open Curtain" id="myButton1" />
...
function change()
{
    document.getElementById("myButton1").value="Close Curtain"; 
}

A faster and simpler solution would be to include the code in your button and use the keyword this to access the button.

<input onclick="this.value='Close Curtain'" type="button" value="Open Curtain" id="myButton1" />

You can edit the generated markup and add

target = "_blank"

your form is missing the method...

<form name="registrationform" action="register.php" method="post"> //here

anywyas to check the posted data u can use isset()..

Determine if a variable is set and is not NULL

if(!isset($firstname) || trim($firstname) == '')
{
   echo "You did not fill out the required fields.";
}

You want an independent for loop for all the rows in grid view, then refer the below link

http://nikhilsreeni.wordpress.com/asp-net/checkbox/

Select all checkbox in Gridview

CheckBox cb = default(CheckBox);
for (int i = 0; i <= grdforumcomments.Rows.Count – 1; i++)
{
    cb = (CheckBox)grdforumcomments.Rows[i].Cells[0].FindControl(“cbSel”);

    cb.Checked = ((CheckBox)sender).Checked;
}

Select checked rows to a dataset; For gridview multiple edit

CheckBox cb = default(CheckBox);

foreach (GridViewRow row in grdforumcomments.Rows)
{
    cb = (CheckBox)row.FindControl("cbsel");
    if (cb.Checked)
    {
        drArticleCommentsUpdates = dtArticleCommentsUpdates.NewRow();
        drArticleCommentsUpdates["Id"] = dgItem.Cells[0].Text;
        drArticleCommentsUpdates["Date"] = System.DateTime.Now;dtArticleCommentsUpdates.Rows.Add(drArticleCommentsUpdates);
    }
}

This is a minor update, but since Java 7, proxy connections can now be created programmatically rather than through system properties. This may be useful if:

1. Proxy needs to be dynamically rotated during the program's runtime
2. Multiple parallel proxies need to be used
3. Or just make your code cleaner :)

Here's a contrived example in groovy:

// proxy configuration read from file resource under "proxyFileName"
String proxyFileName = "proxy.txt"
String proxyPort = "1234"
String url = "http://www.promised.land"
File testProxyFile = new File(proxyFileName)
URLConnection connection

if (!testProxyFile.exists()) {

    logger.debug "proxyFileName doesn't exist.  Bypassing connection via proxy."
    connection = url.toURL().openConnection()

} else {
    String proxyAddress = testProxyFile.text
    connection = url.toURL().openConnection(new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyAddress, proxyPort)))
}

try {
    connection.connect()
}
catch (Exception e) {
    logger.error e.printStackTrace()
}

on button click, first open the database, fetch the data and close the data base like this

public class cytaty extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.galeria);

        Button bLosuj = (Button) findViewById(R.id.button1);
        bLosuj.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            myDatabaseHelper = new DatabaseHelper(cytaty.this);
            myDatabaseHelper.openDataBase();

            String text = myDatabaseHelper.getYourData(); //this is the method to query

            myDatabaseHelper.close(); 
            // set text to your TextView
            }
        });
    }
}

and your getYourData() in database class would be like this

public String[] getAppCategoryDetail() {

    final String TABLE_NAME = "name of table";

    String selectQuery = "SELECT  * FROM " + TABLE_NAME;
    SQLiteDatabase db  = this.getReadableDatabase();
    Cursor cursor      = db.rawQuery(selectQuery, null);
    String[] data      = null;

    if (cursor.moveToFirst()) {
        do {
           // get the data into array, or class variable
        } while (cursor.moveToNext());
    }
    cursor.close();
    return data;
}

Try this command:

find / -name file.look

Step by step and Full instruction for Ubuntu 16.04.4 LTS and Apache/2.4.18

"sudo -s"

"cd /etc/apache2/mods-enabled"

"vi dir.conf" and move index.php to right after DirectoryIndex like below and save file then restart apache server.

DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm

"service apache2 restart"

If you do not see dir.conf then you will need to load it (google for how to)

Done.

Write below code

ImageView yourImageView = (ImageView) findViewById(R.id.yourImageView);
Bitmap bitmap = ((BitmapDrawable)yourImageView.getDrawable()).getBitmap();

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

Everyone else has already answered it, but I think I still have something else to add.

Namedtuple could be intuitively deemed as a shortcut to define a class.

See a cumbersome and conventional way to define a class .

class Duck:
    def __init__(self, color, weight):
        self.color = color
        self.weight = weight
red_duck = Duck('red', '10')

    In [50]: red_duck
    Out[50]: <__main__.Duck at 0x1068e4e10>
    In [51]: red_duck.color
    Out[51]: 'red'

As for namedtuple

from collections import namedtuple
Duck = namedtuple('Duck', ['color', 'weight'])
red_duck = Duck('red', '10')

In [54]: red_duck
Out[54]: Duck(color='red', weight='10')
In [55]: red_duck.color
Out[55]: 'red'

The -o option didn't work for me because the artifact is still in development and not yet uploaded and maven (3.5.x) still tries to download it from the remote repository because it's the first time, according to the error I get.

However this fixed it for me: https://maven.apache.org/general.html#importing-jars

After this manual install there's no need to use the offline option either.

UPDATE

I've just rebuilt the dependency and I had to re-import it: the regular mvn clean install was not sufficient for me

Use prop() instead of attr() to set the value of checked. Also use :checkbox in find method instead of input and be specific.

Live Demo

$("#news_list tr").click(function() {
    var ele = $(this).find('input');
    if(ele.is(':checked')){
        ele.prop('checked', false);
        $(this).removeClass('admin_checked');
    }else{
        ele.prop('checked', true);
        $(this).addClass('admin_checked');
    }
});

Use prop instead of attr for properties like checked

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method

In your NGINX vhost file, in location block which processes your PHP files (usually location ~ \.php$ {) through FastCGI, make sure you have next lines:

proxy_buffer_size          128k;
proxy_buffers              4 256k;
proxy_busy_buffers_size    256k;
fastcgi_buffer_size        16k;
fastcgi_buffers            4 16k;

After that don't forget to restart fpm and nginx.

Additional:

NGINX vhost paths

• /etc/nginx/sites-enabled/ - Linux
• '/usr/local/etc/nginx/sites-enabled/' - Mac

Restart NGINX:

• sudo service nginx restart - Linux
• brew service restart nginx - Mac

Restart FPM:

Determine fpm process name: - systemctl list-unit-files | grep fpm - Linux - brew services list | grep php - Mac

and then restart it with:

• sudo service <service-name> restart - Linux
• brew services restart <service-name> - Mac

Optimized VBScript Solution

I used totymedli's code but found it bogging down when using large ranges (as pointed out by others), so I optimized his code a bit. If anyone is interested in getting unique values using VBScript but finds totymedli's code slow when updating, try this:

    Function listUnique(rng As Range) As Variant
        Dim val As String
        Dim elements() As String
        Dim elementSize As Integer
        Dim newElement As Boolean
        Dim i As Integer
        Dim distance As Integer
        Dim allocationChunk As Integer
        Dim uniqueSize As Integer
        Dim r As Long
        Dim lLastRow  As Long

        lLastRow = rng.End(xlDown).row

        elementSize = 1
        unqueSize = 0

        distance = Range(Application.Caller.Address).row - rng.row

        If distance <> 0 Then
            If Cells(Range(Application.Caller.Address).row - 1, Range(Application.Caller.Address).Column).Value = "" Then
                listUnique = ""
                Exit Function
            End If
        End If

        For r = 1 To lLastRow
            val = rng.Cells(r)
            If val <> "" Then
                newElement = True
                For i = 1 To elementSize - 1 Step 1
                    If elements(i - 1) = val Then
                        newElement = False
                        Exit For
                    End If
                Next i
                If newElement Then
                    uniqueSize = uniqueSize + 1
                    If uniqueSize >= elementSize Then
                        elementSize = elementSize * 2
                        ReDim Preserve elements(elementSize - 1)
                    End If
                    elements(uniqueSize - 1) = val
                End If
            End If
        Next


        If distance < uniqueSize Then
            listUnique = elements(distance)
        Else
            listUnique = ""
        End If
    End Function

fetch("http://localhost:8988/api", {

.then((response) =>response.json());
.then((data) => {

There should be

but not $('.upload')

You may use YQL however yahoo.finance.* tables are not the core yahoo tables. It is an open data table which uses the 'csv api' and converts it to json or xml format. It is more convenient to use but it's not always reliable. I could not use it just a while ago because it the table hits its storage limit or something...

You may use this php library to get historical data / quotes using YQL https://github.com/aygee/php-yql-finance

Migrating

It’s a relatively simple process. First we download fast-export (the best way is via its Git repository, which I’ll clone right to the desktop), then we create a new git repository, perform the migration, and check out the HEAD. On the command line, it goes like this:

cd ~/Desktop
git clone git://repo.or.cz/fast-export.git
git init git_repo
cd git_repo
~/Desktop/fast-export/hg-fast-export.sh -r /path/to/old/mercurial_repo
git checkout HEAD

You should see a long listing of commits fly by as your project is migrated after running fast-export. If you see errors, they are likely related to an improperly specified Python path (see the note above and customize for your system).

That’s it, you’re done.

I think it can't be simpler than this.

const findDuplicates = arr => [...new Set(arr.filter(v => arr.indexOf(v) !== arr.lastIndexOf(v)))];

console.log(findDuplicates([ "q", "w", "w", "e", "i", "u", "r"]));

Here's my solution:

# /initializers/string.rb
class String
  IntegerRegex = /^(\d)+$/

  def integer?
    !!self.match(IntegerRegex)
  end
end

# any_model_or_controller.rb
'12345'.integer? # true
'asd34'.integer? # false

And here's how it works:

• /^(\d)+$/is regex expression for finding digits in any string. You can test your regex expressions and results at http://rubular.com/.
• We save it in a constant IntegerRegex to avoid unnecessary memory allocation everytime we use it in the method.
• integer? is an interrogative method which should return true or false.
• match is a method on string which matches the occurrences as per the given regex expression in argument and return the matched values or nil.
• !! converts the result of match method into equivalent boolean.
• And declaring the method in existing String class is monkey patching, which doesn't change anything in existing String functionalities, but just adds another method named integer? on any String object.

Extensions without enough permission on chrome can cause these warnings, for example for React developer tools, check if the following procedure solves your problem:

1. Right click on the extension icon.

Or

1. Go to extensions.
2. Click the three-dot in the row of React developer tool.

Then choose "this can read and write site data". You should see 3 options in the list, pick one that is strict enough based on how much you trust the extension and also satisfies the extensions's needs.

You can use this:

comment = Comment.objects.filter(pk=comment_id)

I am using the following test to see if strings have been urlencoded:

if(urlencode($str) != str_replace(['%','+'], ['%25','%2B'], $str))

If a string has already been urlencoded, the only characters that will changed by double encoding are % (which starts all encoded character strings) and + (which replaces spaces.) Change them back and you should have the original string.

Let me know if this works for you.

You could do this with maps:

Map<String, String> fileToImg:
List<String> fileList = new ArrayList(fileToImg.keySet());
Collections.shuffle(fileList);
for(String item: fileList) {
    fileToImf.get(item);
}

This will iterate through the images in the random order.

Consider a binary tree whose nodes are drawn in a tree fashion. Now start numbering the nodes from top to bottom and left to right. A complete tree has these properties:

If n has children then all nodes numbered less than n have two children.

If n has one child it must be the left child and all nodes less than n have two children. In addition no node numbered greater than n has children.

If n has no children then no node numbered greater than n has children.

A complete binary tree can be used to represent a heap. It can be easily represented in contiguous memory with no gaps (i.e. all array elements are used save for any space that may exist at the end).

I suspect its a new feature since this post was created - pass parameters to the script block using $Using:var. Then its a simple mater to pass parameters provided the script is already on the machine or in a known network location relative to the machine

Taking the main example it would be:

icm -cn $Env:ComputerName { 
    C:\Scripts\ArchiveEventLogs\ver5\ArchiveEventLogs.ps1 -one "uno" -two "dos" -Debug -Clear $Using:Clear
}

When I first started out learning the for in and of loop, I was confused with my output too, but with a couple of research and understanding you can think of the individual loop like the following : The

1. for...in loop returns the indexes of the individual property and has no effect of impact on the property's value, it loops and returns information on the property and not the value. E.g

let profile = { name : "Naphtali", age : 24, favCar : "Mustang", favDrink : "Baileys" }

The above code is just creating an object called profile, we'll use it for both our examples, so, don't be confused when you see the profile object on an example, just know it was created.

So now let us use the for...in loop below

for(let myIndex in profile){
    console.log(`The index of my object property is ${myIndex}`)
}
 // Outputs : 
        The index of my object property is 0
        The index of my object property is 1
        The index of my object property is 2
        The index of my object property is 3

Now Reason for the output being that we have Four(4) properties in our profile object and indexing as we all know starts from 0...n, so, we get the index of properties 0,1,2,3 since we are working with the for..in loop.

2. for...of loop* can return either the property, value or both, Let's take a look at how. In javaScript, we can't loop through objects normally as we would on arrays, so, there are a few elements we can use to access either of our choices from an object.

   • Object.keys(object-name-goes-here) >>> Returns the keys or properties of an object.

   • Object.values(object-name-goes-here) >>> Returns the values of an object.

   • Object.entries(object-name-goes-here) >>> Returns both the keys and values of an object.

Below are examples of their usage, pay attention to Object.entries() :

Step One: Convert the object to get either its key, value, or both.
Step Two: loop through.


// Getting the keys/property

   Step One: let myKeys = ***Object.keys(profile)***
   Step Two: for(let keys of myKeys){
             console.log(`The key of my object property is ${keys}`)
           }

// Getting the values of the property

    Step One: let myValues = ***Object.values(profile)***
    Step Two : for(let values of myValues){
                 console.log(`The value of my object property is ${values}`)
               }

When using Object.entries() have it that you are calling two entries on the object, i.e the keys and values. You can call both by either of the entry. Example Below.

Step One: Convert the object to entries, using ***Object.entries(object-name)***
Step Two: **Destructure** the ***entries object which carries the keys and values*** 
like so **[keys, values]**, by so doing, you have access to either or both content.


    // Getting the keys/property

       Step One: let myKeysEntry = ***Object.entries(profile)***
       Step Two: for(let [keys, values] of myKeysEntry){
                 console.log(`The key of my object property is ${keys}`)
               }

    // Getting the values of the property

        Step One: let myValuesEntry = ***Object.entries(profile)***
        Step Two : for(let [keys, values] of myValuesEntry){
                     console.log(`The value of my object property is ${values}`)
                   }

    // Getting both keys and values

        Step One: let myBothEntry = ***Object.entries(profile)***
        Step Two : for(let [keys, values] of myBothEntry){
                     console.log(`The keys of my object is ${keys} and its value 
is ${values}`)
                   }

Omar's third solution as an HTML Helper would be:

public static IHtmlString FormatNewLines(this HtmlHelper helper, string input)
{
    return helper.Raw(helper.Encode(input).Replace("\n", "<br />"));
}

If you are using command line tools, then you can also set it in the shell.

On linux, with a sh type shell, you can do for example:

export NLS_TIMESTAMP_FORMAT='DD/MON/RR HH24:MI:SSXFF'

Then you can use the command line tools and it will use the specified format:

/path/to/dbhome_1/bin/sqlldr user/pass@host:port/service control=table.ctl direct=true

As of git v1.7.2 cherry pick can accept a range of commits:

git cherry-pick learned to pick a range of commits (e.g. cherry-pick A..B and cherry-pick --stdin), so did git revert; these do not support the nicer sequencing control rebase [-i] has, though.

If we consider the below example for converting the json format file to csv formatted file.

{
 "item_data" : [
      {
        "item": "10023456",
        "class": "100",
        "subclass": "123"
      }
      ]
}

The below code will convert the json file ( data3.json ) to csv file ( data3.csv ).

import json
import csv
with open("/Users/Desktop/json/data3.json") as file:
    data = json.load(file)
    file.close()
    print(data)

fname = "/Users/Desktop/json/data3.csv"

with open(fname, "w", newline='') as file:
    csv_file = csv.writer(file)
    csv_file.writerow(['dept',
                       'class',
                       'subclass'])
    for item in data["item_data"]:
         csv_file.writerow([item.get('item_data').get('dept'),
                            item.get('item_data').get('class'),
                            item.get('item_data').get('subclass')])

The above mentioned code has been executed in the locally installed pycharm and it has successfully converted the json file to the csv file. Hope this help to convert the files.

A Functor is a object which acts like a function. Basically, a class which defines operator().

class MyFunctor
{
   public:
     int operator()(int x) { return x * 2;}
}

MyFunctor doubler;
int x = doubler(5);

The real advantage is that a functor can hold state.

class Matcher
{
   int target;
   public:
     Matcher(int m) : target(m) {}
     bool operator()(int x) { return x == target;}
}

Matcher Is5(5);

if (Is5(n))    // same as if (n == 5)
{ ....}

There are plenty of good solutions already, but here's a solution that I find more elegant for the way I want to work:

I put a script in my path called "git-put" that contains:

#!/bin/bash
git commit "$@" && git push -u

That allows me to run:

git put -am"my commit message"

..to add all files, commit them, and push them.

(I also added the "-u" because I like to do this anyway, even though it's not related to this issue. It ensures that the upstream branch is always set up for pulling.)

I like this approach because it also allows to to use "git put" without adding all the files (skip the "-a"), or with any other options I might want to pass to commit. Also, "put" is a short portmanteau of "push" and "commit"

For json to xml use the following Jackson example:

final String str = "{\"name\":\"JSON\",\"integer\":1,\"double\":2.0,\"boolean\":true,\"nested\":{\"id\":42},\"array\":[1,2,3]}";
ObjectMapper jsonMapper = new ObjectMapper();
JsonNode node = jsonMapper.readValue(str, JsonNode.class);
XmlMapper xmlMapper = new XmlMapper();
        xmlMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
        xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);
        xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_1_1, true);
StringWriter w = new StringWriter();
xmlMapper.writeValue(w, node);
System.out.println(w.toString());

Prints:

<?xml version='1.1' encoding='UTF-8'?>
<ObjectNode>
  <name>JSON</name>
  <integer>1</integer>
  <double>2.0</double>
  <boolean>true</boolean>
  <nested>
    <id>42</id>
  </nested>
  <array>1</array>
  <array>2</array>
  <array>3</array>
</ObjectNode>

To convert it back (xml to json) take a look at this answer https://stackoverflow.com/a/62468955/1485527 .

public string Author {get;set;}

Controller

public class BookController : Controller

     [HttpPost]
     public ActionResult Create(Book model, IEnumerable<HttpPostedFileBase> fileUpload)
     {
         throw new NotImplementedException();

     @Html.EditorFor(m => m)

     <input type="file" name="fileUpload[0]" /><br />

     <input type="file" name="fileUpload[2]" /><br />      

     <input type="submit" name="Submit" id="SubmitMultiply" value="Upload" />
}

Note title of parameter from controller action must match with name of input elements IEnumerable<HttpPostedFileBase> fileUpload -> name="fileUpload[0]"

fileUpload must match

If you are using ATL/MFC CString, simply call CString::MakeReverse().

In C, using a previously undeclared function constitutes an implicit declaration of the function. In an implicit declaration, the return type is int if I recall correctly. Now, GCC has built-in definitions for some standard functions. If an implicit declaration does not match the built-in definition, you get this warning.

To fix the problem, you have to declare the functions before using them; normally you do this by including the appropriate header. I recommend not to use the -fno-builtin-* flags if possible.

Instead of stdlib.h, you should try:

#include <string.h>

That's where strcpy and strncpy are defined, at least according to the strcpy(2) man page.

The exit function is defined in stdlib.h, though, so I don't know what's going on there.

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

As an alternative to the answers you already have, and for others that come accross this post. I recently had a similar task and created a small jquery plug in to do it for me. Its pretty small under 3KB minified, and has sorting, paging and the ability to show and hide columns.

It should be pretty easy to customize using css. More information can be found here http://mrjsontable.azurewebsites.net/ and the project is available for you to do as you wish with on github https://github.com/MatchingRadar/Mr.JsonTable

To get it to work download the files and pop them in your site. Follow the instructions and you should end up with something like the following:

<div id="citytable"></div>

Then in the ajax success method you will want something like this

success: function(data){ 
    $("#citytable").mrjsontable({
        tableClass: "my-table",
        pageSize: 10, //you can change the page size here
        columns: [
            new $.fn.mrjsontablecolumn({
                heading: "City",
                data: "city"
            }),
            new $.fn.mrjsontablecolumn({
                heading: "City Status",
                data: "cStatus"
            })
        ],
        data: data
    });
}

Hope it helps somebody else!

=COUNTIFS(1:1,FALSE)=0

This will return TRUE or FALSE (Looks for FALSE, if count isn't 0 (all True) it will be false

VB.NET:

If(someBool, "true", "false")

C#

someBool ? "true" : "false";

Previously posted solutions did not work for me. cell.getRawValue() returned the same formula as stated in the cell. The following function worked for me:

public void readFormula() throws IOException {
    FileInputStream fis = new FileInputStream("Path of your file");
    Workbook wb = new XSSFWorkbook(fis);
    Sheet sheet = wb.getSheetAt(0);
    FormulaEvaluator evaluator = wb.getCreationHelper().createFormulaEvaluator();

    CellReference cellReference = new CellReference("C2"); // pass the cell which contains the formula
    Row row = sheet.getRow(cellReference.getRow());
    Cell cell = row.getCell(cellReference.getCol());

    CellValue cellValue = evaluator.evaluate(cell);

    switch (cellValue.getCellType()) {
        case Cell.CELL_TYPE_BOOLEAN:
            System.out.println(cellValue.getBooleanValue());
            break;
        case Cell.CELL_TYPE_NUMERIC:
            System.out.println(cellValue.getNumberValue());
            break;
        case Cell.CELL_TYPE_STRING:
            System.out.println(cellValue.getStringValue());
            break;
        case Cell.CELL_TYPE_BLANK:
            break;
        case Cell.CELL_TYPE_ERROR:
            break;

        // CELL_TYPE_FORMULA will never happen
        case Cell.CELL_TYPE_FORMULA:
            break;
    }

}

Add an EditText on top of your listview in its .xml layout file. And in your activity/fragment..

lv = (ListView) findViewById(R.id.list_view);
    inputSearch = (EditText) findViewById(R.id.inputSearch);

// Adding items to listview
adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.product_name,    products);
lv.setAdapter(adapter);       
inputSearch.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
        // When user changed the Text
        MainActivity.this.adapter.getFilter().filter(cs);
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }

    @Override
    public void afterTextChanged(Editable arg0) {}
});

The basic here is to add an OnTextChangeListener to your edit text and inside its callback method apply filter to your listview's adapter.

EDIT

To get filter to your custom BaseAdapter you"ll need to implement Filterable interface.

class CustomAdapter extends BaseAdapter implements Filterable {

    public View getView(){
    ...
    }
    public Integer getCount()
    {
    ...
    }

    @Override
    public Filter getFilter() {

        Filter filter = new Filter() {

            @SuppressWarnings("unchecked")
            @Override
            protected void publishResults(CharSequence constraint, FilterResults results) {

                arrayListNames = (List<String>) results.values;
                notifyDataSetChanged();
            }

            @Override
            protected FilterResults performFiltering(CharSequence constraint) {

                FilterResults results = new FilterResults();
                ArrayList<String> FilteredArrayNames = new ArrayList<String>();

                // perform your search here using the searchConstraint String.

                constraint = constraint.toString().toLowerCase();
                for (int i = 0; i < mDatabaseOfNames.size(); i++) {
                    String dataNames = mDatabaseOfNames.get(i);
                    if (dataNames.toLowerCase().startsWith(constraint.toString()))  {
                        FilteredArrayNames.add(dataNames);
                    }
                }

                results.count = FilteredArrayNames.size();
                results.values = FilteredArrayNames;
                Log.e("VALUES", results.values.toString());

                return results;
            }
        };

        return filter;
    }
}

Inside performFiltering() you need to do actual comparison of the search query to values in your database. It will pass its result to publishResults() method.

I'm not sure if this answers your question, but for example:

if (A || B)
{
    Console.WriteLine("Or");
}

if (A && B)
{
    Console.WriteLine("And");
}

Check out this full code. you can use the containers in percentages like below code:

<html>
<head>
<title>How to make Iframe Responsive</title>
<style>
html,body        {height:100%;}
.wrapper         {width:80%;height:100%;margin:0 auto;background:#CCC}
.h_iframe        {position:relative;}
.h_iframe .ratio {display:block;width:100%;height:auto;}
.h_iframe iframe {position:absolute;top:0;left:0;width:100%; height:100%;}
</style>
</head>
<body>
<div class="wrapper">
<div class="h_iframe">
<img class="ratio" src=""/>
<iframe src="http://www.sanwebcorner.com" frameborder="0" allowfullscreen></iframe>
</div>
<p>Please scale the "result" window to notice the effect.</p>
</div>
</body>
</html>

Check out this demo Page.

This should work

<option *ngFor="let title of titleArray" 
    [value]="title.Value" 
    [attr.selected]="passenger.Title==title.Text ? true : null">
  {{title.Text}}
</option>

I'm not sure the attr. part is necessary.

Position absolute fixes it for me. I suggest also adding a semi-colon if you haven't already.

.container {
    width: 22.5%;
    size: 22.5% 22.5%;
    margin-top: 0%;
    border-radius: 10px;
    background-color: floralwhite;
    display:inline-block;
    min-height: 20%;
    position: absolute;
    height: 50%;
}

Based on the code I've used for finding multiple instances of a string within a larger string, your code would look like:

List<int> inst = new List<int>();
int index = 0;
while (index >=0)
{
    index = source.IndexOf("extract\"(me,i-have lots. of]punctuation", index);
    inst.Add(index);
    index++;
}

For me following steps worked:

1. Quit Xcode.
2. Open Terminal.
3. Typed Command xattr -rc /Users/manabkumarmal/Desktop/Projects/MyProjectHome
4. Open Xcode.
5. Cleaned.
6. Now worked and No Error.

What exactly are the rules for requesting retransmission of lost data?

The receiver does not request the retransmission. The sender waits for an ACK for the byte-range sent to the client and when not received, resends the packets, after a particular interval. This is ARQ (Automatic Repeat reQuest). There are several ways in which this is implemented.

Stop-and-wait ARQ
Go-Back-N ARQ
Selective Repeat ARQ

are detailed in the RFC 3366.

At what time frequency are the retransmission requests performed?

The retransmissions-times and the number of attempts isn't enforced by the standard. It is implemented differently by different operating systems, but the methodology is fixed. (One of the ways to fingerprint OSs perhaps?)

The timeouts are measured in terms of the RTT (Round Trip Time) times. But this isn't needed very often due to Fast-retransmit which kicks in when 3 Duplicate ACKs are received.

Is there an upper bound on the number?

Yes there is. After a certain number of retries, the host is considered to be "down" and the sender gives up and tears down the TCP connection.

Is there functionality for the client to indicate to the server to forget about the whole TCP segment for which part went missing when the IP packet went missing?

The whole point is reliable communication. If you wanted the client to forget about some part, you wouldn't be using TCP in the first place. (UDP perhaps?)

I can't say it's an appropriate solution but you can try this.

Steps

• I am hoping that you have already cloned your repo.
• Now copy the file somewhere outside of your project.
• Add that filename with a location in gitigonre file.
• Remove that file from your local project.
• Push your code to remote origin.
• And now add that copied file into your project it'll be ignored.

This is just a hack solution if you want to maintain the history and don't to create mass in it.

If you don't want to use this solution please kindly ignore and try to avoid devote it. Because I am really trying to increase my score on this side

If you save color code in the colors.xml which is under the values folder,then you should call the following:

root.setBackgroundColor(getResources().getColor(R.color.name));

name means you declare in the <color/> tag.

I was having the same problem just now. I solved it by uninstalling the latest Connector/NET drivers (6.7.4) and then installed the older drivers (6.6.5) and it works.

I am using Visual Studio 2010. I uninstalled the latest ones because I figured they were somehow related to .NET4.5, which I'm not able to use.

Update #1:

Supposedly another way is to register the MySql Connector with various Visual Studio versions (2010/2012/2013/2015...) during installation: Go to Modify Product Features and select all the relevant Visual Studio versions.

Update #2 - Visual Studio 2019 Update:

When I installed MySQL Community with the ConnectorNET and VisualStudio Plugin options included - MySQL didn't show up as a data provider in Visual Studio.

The installer I used included the VS Plugin version 1.2.9, which had supposedly fixed installation issues from 1.2.8, but still didn't work for me...

The solution for me was to uninstall the Connector and the Visual Studio Plugin, download them as individual components, and then install them separately (not as part of the MySQLServer Installer). Install the Connector first, then VS plugin after.

• Connector Download
• VS Plugin Download

I found the solution here, Thanks to @LambertHeenan.

NOTE about Visual Studio Express

The OP asks whether MySQL is supported with Visual Studio Express (which as far as I can tell has been renamed to Visual Studio Community). In the past MySQL officially didn't support Visual Studio Express, as per @Paul's answer below, but they do officially support Visual Studio Community 2017 and 2019, according to this page.

Which version of Bootstrap are you using? I was perplexed that I could get @Chad's solution to work in jsfiddle, but not locally. So, I checked the version of Bootstrap used by jsfiddle, and it's using a 3.0.0-rc1 release, while the default download on getbootstrap.com is version 2.3.2.

In 2.3.2 the collapse class wasn't getting replaced by the in class. The in class was simply getting appended when the button was clicked. In version 3.0.0-rc1, the collapse class correctly is removed, and the <tr> collapses.

Use @Chad's solution for the html, and try using these links for referencing Bootstrap:

<link href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0-rc1/css/bootstrap.min.css" rel="stylesheet">
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.0.0-rc1/js/bootstrap.min.js"></script>

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

The only way to do this is to iterate over the array. Obviously if you are sure that the results are ordered by id you can do a binary search

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

this code will work with OI File Manager :

        File root = new File(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
        Uri uri = Uri.fromFile(root);

        Intent intent = new Intent();
        intent.setAction(android.content.Intent.ACTION_VIEW);
        intent.setData(uri);
        startActivityForResult(intent, 1);

you can get OI File manager here : http://www.openintents.org/en/filemanager

The HTTP Content-Type for .ogg should be application/ogg (video/ogg for .ogv) and for .mp4 it should be video/mp4. You can check using the Web Sniffer.

If you already know the item is a String, I prefer:

String itemText = (String) mySpinner.getSelectedItem();

Calling toString() on an Object that you know is a String seems like a more roundabout path than just casting the Object to String.

Here's a one-liner using LINQ and avoiding any run-time evaluation of select strings:

someDataTable.Rows.Cast<DataRow>().Where(
    r => r.ItemArray[0] == someValue).ToList().ForEach(r => r.Delete());

Lookarounds are zero width assertions. They check for a regex (towards right or left of the current position - based on ahead or behind), succeeds or fails when a match is found (based on if it is positive or negative) and discards the matched portion. They don't consume any character - the matching for regex following them (if any), will start at the same cursor position.

Read regular-expression.info for more details.

• Positive lookahead:

Syntax:

(?=REGEX_1)REGEX_2

Match only if REGEX_1 matches; after matching REGEX_1, the match is discarded and searching for REGEX_2 starts at the same position.

example:

(?=[a-z0-9]{4}$)[a-z]{1,2}[0-9]{2,3}

REGEX_1 is [a-z0-9]{4}$ which matches four alphanumeric chars followed by end of line.
REGEX_2 is [a-z]{1,2}[0-9]{2,3} which matches one or two letters followed by two or three digits.

REGEX_1 makes sure that the length of string is indeed 4, but doesn't consume any characters so that search for REGEX_2 starts at the same location. Now REGEX_2 makes sure that the string matches some other rules. Without look-ahead it would match strings of length three or five.

• Negative lookahead

Syntax:

(?!REGEX_1)REGEX_2

Match only if REGEX_1 does not match; after checking REGEX_1, the search for REGEX_2 starts at the same position.

example:

(?!.*\bFWORD\b)\w{10,30}$

The look-ahead part checks for the FWORD in the string and fails if it finds it. If it doesn't find FWORD, the look-ahead succeeds and the following part verifies that the string's length is between 10 and 30 and that it contains only word characters a-zA-Z0-9_

Look-behind is similar to look-ahead: it just looks behind the current cursor position. Some regex flavors like javascript doesn't support look-behind assertions. And most flavors that support it (PHP, Python etc) require that look-behind portion to have a fixed length.

• Atomic groups basically discards/forgets the subsequent tokens in the group once a token matches. Check this page for examples of atomic groups

subprocess: The subprocess module allows you to spawn new processes, connect to their input/output/error pipes, and obtain their return codes.

http://docs.python.org/library/subprocess.html

Usage:

import subprocess
process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)
process.wait()
print process.returncode

This is because $pjs is an one-element-array of objects, so first you should access the array element, which is an object and then access its attributes.

echo $pjs[0]->player_name;

Actually dump result that you pasted tells it very clearly.

In my case the debugged code in JBoss was older than the code in the Eclipse project. Rebuilding the .war solved the problem.

Here is one more robust version from Protocol Buffer

char* string_as_array(string* str)
{
    return str->empty() ? NULL : &*str->begin();
}

// test codes
std::string mystr("you are here");
char* pstr = string_as_array(&mystr);
cout << pstr << endl; // you are here

The existing solutions fail when there are multiple parts to an extension. The function below works for multiple parts, a full path or just a a filename:

function removeExt($path)
{
    $basename = basename($path);
    return strpos($basename, '.') === false ? $path : substr($path, 0, - strlen($basename) + strlen(explode('.', $basename)[0]));
}

echo removeExt('https://example.com/file.php');
// https://example.com/file
echo removeExt('https://example.com/file.tar.gz');
// https://example.com/file
echo removeExt('file.tar.gz');
// file
echo removeExt('file');
// file

There are two classes that lives in different assemblies and different namespaces.

• WinForms: use following namespace declaration, make sure Main is marked with [STAThread] attribute:

  using System.Windows.Forms;
  

• WPF: use following namespace declaration

  using System.Windows;
  

• console: add reference to System.Windows.Forms, use following namespace declaration, make sure Main is marked with [STAThread] attribute. Step-by-step guide in another answer

  using System.Windows.Forms;
  

To copy an exact string (literal in this case):

Clipboard.SetText("Hello, clipboard");

To copy the contents of a textbox either use TextBox.Copy() or get text first and then set clipboard value:

Clipboard.SetText(txtClipboard.Text);

See here for an example. Or... Official MSDN documentation or Here for WPF.

Remarks:

• Clipboard is desktop UI concept, trying to set it in server side code like ASP.Net will only set value on the server and has no impact on what user can see in they browser. While linked answer lets one to run Clipboard access code server side with SetApartmentState it is unlikely what you want to achieve.

• If after following information in this question code still gets an exception see "Current thread must be set to single thread apartment (STA)" error in copy string to clipboard

• This question/answer covers regular .NET, for .NET Core see - .Net Core - copy to clipboard?

There are two Things you can do

use

int noOfColumns = sh.getRow(0).getPhysicalNumberOfCells();

or

int noOfColumns = sh.getRow(0).getLastCellNum();

There is a fine difference between them

1. Option 1 gives the no of columns which are actually filled with contents(If the 2nd column of 10 columns is not filled you will get 9)
2. Option 2 just gives you the index of last column. Hence done 'getLastCellNum()'

I try to write working code example, I test it and everything works.

Hare is code:

HTML:

<input type="file" class="attachment_input" name="file" onchange="checkFileSize(this, @Model.MaxSize.ToString(),@Html.Raw(Json.Encode(Model.FileExtensionsList)))" />

Javascript:

 //function for check attachment size and extention match
function checkFileSize(element, maxSize, extentionsArray) {
    var val = $(element).val(); //get file value

    var ext = val.substring(val.lastIndexOf('.') + 1).toLowerCase(); // get file extention 
    if ($.inArray(ext, extentionsArray) == -1) {
        alert('false extension!');
    }

    var fileSize = ($(element)[0].files[0].size / 1024 / 1024); //size in MB
    if (fileSize > maxSize) {
        alert("Large file");// if Maxsize from Model > real file size alert this
    }
}

First convert it to std::wstring:

std::wstring widestr = std::wstring(str.begin(), str.end());

Then get the C string:

const wchar_t* widecstr = widestr.c_str();

This only works for ASCII strings, but it will not work if the underlying string is UTF-8 encoded. Using a conversion routine like MultiByteToWideChar() ensures that this scenario is handled properly.

Newer versions of Groovy (1.7.2+) offer a JDK extension to more easily traverse over files in a directory, for example:

import static groovy.io.FileType.FILES
def dir = new File(".");
def files = [];
dir.traverse(type: FILES, maxDepth: 0) { files.add(it) };

See also [1] for more examples.

[1] http://mrhaki.blogspot.nl/2010/04/groovy-goodness-traversing-directory.html

You can do that by adding a check on where you're at in the cellForRowAtIndexPath: method. This method is easy to understand and to implement :

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Classic start method
    static NSString *cellIdentifier = @"MyCell";
    MyCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (!cell)
    {
        cell = [[MyCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MainMenuCellIdentifier];
    }

    MyData *data = [self.dataArray objectAtIndex:indexPath.row];
    // Do your cell customisation
    // cell.titleLabel.text = data.title;

    BOOL lastItemReached = [data isEqual:[[self.dataArray] lastObject]]; 
    if (!lastItemReached && indexPath.row == [self.dataArray count] - 1)
    {
        [self launchReload];
    }
}

EDIT : added a check on last item to prevent recursion calls. You'll have to implement the method defining whether the last item has been reached or not.

EDIT2 : explained lastItemReached

You could just use the bound ng-model (answers[item.questID]) value itself in your ng-change method to detect if it has been checked or not.

Example:-

<input type="checkbox" ng-model="answers[item.questID]" 
     ng-change="stateChanged(item.questID)" /> <!-- Pass the specific id -->

and

$scope.stateChanged = function (qId) {
   if($scope.answers[qId]){ //If it is checked
       alert('test');
   }
}

You are getting the WebView before setting the Content view so the wv is probably null.

public class ViewWeb extends Activity {  
        @Override  
        public void onCreate(Bundle savedInstanceState) {  
            super.onCreate(savedInstanceState);
            setContentView(R.layout.webview);  
            WebView wv;  
            wv = (WebView) findViewById(R.id.webView1);  
            wv.loadUrl("file:///android_asset/aboutcertified.html");   // now it will not fail here
        }  
    }

Use JQuery keydown event.

$(document).keypress(function(){
    if(event.which == 70){  //f
        console.log("You have payed respect");
    }
});

In JS; keyboard keys are identified by Javascript keycodes

If you are using some trackers like google analytics or amplitude and you are trying to release your app in another platforms other than Google Play, this errors appears for users. So there are two possible solutions:

1. Use special trackers in your app (firebase and appmetrica are tested and are ok)
2. Release your app in Google Play

In a new window using Pillow/PIL

Install Pillow (or PIL), e.g.:

$ pip install pillow

Now you can

from PIL import Image
with Image.open('path/to/file.jpg') as img:
    img.show()

Using native apps

Other common alternatives include running xdg-open or starting the browser with the image path:

import webbrowser
webbrowser.open('path/to/file.jpg')

Inline a Linux console

If you really want to show the image inline in the console and not as a new window, you may do that but only in a Linux console using fbi see ask Ubuntu or else use ASCII-art like CACA.

Security researchers Jean-Baptiste Bédrune and Jean Sigwald presented how to do this at Hack-in-the-box Amsterdam 2011.

Since then, Apple has released an iOS Security Whitepaper with more details about keys and algorithms, and Charlie Miller et al. have released the iOS Hacker’s Handbook, which covers some of the same ground in a how-to fashion. When iOS 10 first came out there were changes to the backup format which Apple did not publicize at first, but various people reverse-engineered the format changes.

Encrypted backups are great

The great thing about encrypted iPhone backups is that they contain things like WiFi passwords that aren’t in regular unencrypted backups. As discussed in the iOS Security Whitepaper, encrypted backups are considered more “secure,” so Apple considers it ok to include more sensitive information in them.

An important warning: obviously, decrypting your iOS device’s backup removes its encryption. To protect your privacy and security, you should only run these scripts on a machine with full-disk encryption. While it is possible for a security expert to write software that protects keys in memory, e.g. by using functions like VirtualLock() and SecureZeroMemory() among many other things, these Python scripts will store your encryption keys and passwords in strings to be garbage-collected by Python. This means your secret keys and passwords will live in RAM for a while, from whence they will leak into your swap file and onto your disk, where an adversary can recover them. This completely defeats the point of having an encrypted backup.

How to decrypt backups: in theory

The iOS Security Whitepaper explains the fundamental concepts of per-file keys, protection classes, protection class keys, and keybags better than I can. If you’re not already familiar with these, take a few minutes to read the relevant parts.

Now you know that every file in iOS is encrypted with its own random per-file encryption key, belongs to a protection class, and the per-file encryption keys are stored in the filesystem metadata, wrapped in the protection class key.

To decrypt:

1. Decode the keybag stored in the BackupKeyBag entry of Manifest.plist. A high-level overview of this structure is given in the whitepaper. The iPhone Wiki describes the binary format: a 4-byte string type field, a 4-byte big-endian length field, and then the value itself.

   The important values are the PBKDF2 ITERations and SALT, the double protection salt DPSL and iteration count DPIC, and then for each protection CLS, the WPKY wrapped key.

2. Using the backup password derive a 32-byte key using the correct PBKDF2 salt and number of iterations. First use a SHA256 round with DPSL and DPIC, then a SHA1 round with ITER and SALT.

   Unwrap each wrapped key according to RFC 3394.

3. Decrypt the manifest database by pulling the 4-byte protection class and longer key from the ManifestKey in Manifest.plist, and unwrapping it. You now have a SQLite database with all file metadata.

4. For each file of interest, get the class-encrypted per-file encryption key and protection class code by looking in the Files.file database column for a binary plist containing EncryptionKey and ProtectionClass entries. Strip the initial four-byte length tag from EncryptionKey before using.

   Then, derive the final decryption key by unwrapping it with the class key that was unwrapped with the backup password. Then decrypt the file using AES in CBC mode with a zero IV.

How to decrypt backups: in practice

First you’ll need some library dependencies. If you’re on a mac using a homebrew-installed Python 2.7 or 3.7, you can install the dependencies with:

CFLAGS="-I$(brew --prefix)/opt/openssl/include" \
LDFLAGS="-L$(brew --prefix)/opt/openssl/lib" \    
    pip install biplist fastpbkdf2 pycrypto

That code no longer works on backups from phones using the latest iOS, but there are some golang ports that have been kept up to date allowing access to the keychain.

I think why you want to zoom-in and zoom-out the image view is because your image view is small and zooming in the image there will not let the image come out of the image view. Instead, image starts disappearing from the boundaries while zooming in. So letting the image come out of the image while we zoom in is what you want I guess.

So there are two tricks (according to me) to achieve this-

1. Change the layout params of the image view to cover the whole outermost view or view group at runtime while we are about to zoom-in the image.
2. Make an expanded Image view or Full Image View (height and width = Outermost View or View Group) in xml file and set it's visibility to gone. When we are about to zoom-in the image, load the image from small Image View into full Img View, map the image in fullImgView to image in smallImgView and make it's view visible.

Trick no.1 does not work when the image View is nested very much inside other views (like in nested recycler view)

Trick no.2 works always :-)

Here is the implementation of trick no.2 -

public class ZoomOnTouchListener extends AppCompatActivity implements View.OnTouchListener {

    private Matrix matrix = new Matrix();

    private boolean isfullImgViewActive = false;
    // above boolean gets true when when we firstly move 2 fingers on the smallImgView and in this case smallImgView gets invisible and fullImgView gets visible
    // and false if smallImgView is visible and fullImgView is gone

    private float[] matrixArray = new float[9];
    private float orgScale;

    private PointF start = new PointF();
    private PointF prevP1 = new PointF();
    private PointF prevP2 = new PointF();
    private PointF mid = new PointF();
    private float oldDist = 1f;

    private ImageView mfullImgView;
    private ImageView smallImgView;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mfullImgView = (ImageView)findViewById(R.id.imgView2);
        mfullImgView.setVisibility(View.GONE);
        smallImgView = (ImageView)findViewById(R.id.imgView);
        smallImgView.setOnTouchListener(this);    

    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {

}

NOTE:- Don't set OnClickListener to mfullImgView before setting onTouchListener to it. Setting that will let the fullImageView(if it is visible) steal the touch event of putting second finger down after lifting it for the first time because we want to let the smallImgView take all the touch events until all the fingers are lifted up for the first time.

This is an easy way to create custom events and raise them. You create a delegate and an event in the class you are throwing from. Then subscribe to the event from another part of your code. You have already got a custom event argument class so you can build on that to make other event argument classes. N.B: I have not compiled this code.

public partial class Form1 : Form
{
    private TestClass _testClass;
    public Form1()
    {
        InitializeComponent();
        _testClass = new TestClass();
        _testClass.OnUpdateStatus += new TestClass.StatusUpdateHandler(UpdateStatus);
    }

    private void UpdateStatus(object sender, ProgressEventArgs e)
    {
        SetStatus(e.Status);
    }

    private void SetStatus(string status)
    {
        label1.Text = status;
    }

    private void button1_Click_1(object sender, EventArgs e)
    {
         TestClass.Func();
    }

}

public class TestClass
{
    public delegate void StatusUpdateHandler(object sender, ProgressEventArgs e);
    public event StatusUpdateHandler OnUpdateStatus;

    public static void Func()
    {
        //time consuming code
        UpdateStatus(status);
        // time consuming code
        UpdateStatus(status);
    }

    private void UpdateStatus(string status)
    {
        // Make sure someone is listening to event
        if (OnUpdateStatus == null) return;

        ProgressEventArgs args = new ProgressEventArgs(status);
        OnUpdateStatus(this, args);
    }
}

public class ProgressEventArgs : EventArgs
{
    public string Status { get; private set; }

    public ProgressEventArgs(string status)
    {
        Status = status;
    }
}

There are already great answers about the advantages of using list initialization, however my personal rule of thumb is NOT to use curly braces whenever possible, but instead make it dependent on the conceptual meaning:

• If the object I'm creating conceptually holds the values I'm passing in the constructor (e.g. containers, POD structs, atomics, smart pointers etc.), then I'm using the braces.
• If the constructor resembles a normal function call (it performs some more or less complex operations that are parametrized by the arguments) then I'm using the normal function call syntax.
• For default initialization I always use curly braces.
  For one, that way I'm always sure that the object gets initialized irrespective of whether it e.g. is a "real" class with a default constructor that would get called anyway or a builtin / POD type. Second it is - in most cases - consistent with the first rule, as a default initialized object often represents an "empty" object.

In my experience, this ruleset can be applied much more consistently than using curly braces by default, but having to explicitly remember all the exceptions when they can't be used or have a different meaning than the "normal" function-call syntax with parenthesis (calls a different overload).

It e.g. fits nicely with standard library-types like std::vector:

vector<int> a{10,20};   //Curly braces -> fills the vector with the arguments

vector<int> b(10,20);   //Parentheses -> uses arguments to parametrize some functionality,                          
vector<int> c(it1,it2); //like filling the vector with 10 integers or copying a range.

vector<int> d{};      //empty braces -> default constructs vector, which is equivalent
                      //to a vector that is filled with zero elements

In Bash I prefer doing this as it addresses itself more as a conditional operation unlike using (( )) which is more of arithmetic.

[[ N -gt M ]]

Unless I do complex stuffs like

(( (N + 1) > M ))

But everyone just has their own preferences. Sad thing is that some people impose their unofficial standards.

Update:

You actually can also do this:

[[ 'N + 1' -gt M ]]

Which allows you to add something else which you could do with [[ ]] besides arithmetic stuff.

Why not simply return your calculated value and let the caller modify the global variable. It's not a good idea to manipulate a global variable within a function, as below:

Var1 = 1
Var2 = 0

def function(): 
    if Var2 == 0 and Var1 > 0:
        print("Result One")
    elif Var2 == 1 and Var1 > 0:
        print("Result Two")
    elif Var1 < 1:
        print("Result Three")
    return Var1 - 1

Var1 = function()

or even make local copies of the global variables and work with them and return the results which the caller can then assign appropriately

def function():
v1, v2 = Var1, Var2
# calculate using the local variables v1 & v2
return v1 - 1

Var1 = function()

You can do a variety of things. What I would do is this.

Create an array on scope that will be your data structure for the phone numbers.

$scope.telephone = '';
$scope.numbers = [];

Then in your html I would have this

<input type="text" ng-model="telephone">
<button ng-click="submitNumber()">Submit</button>

Then when your user clicks submit, run submitNumber(), which pushes the new telephone number into the numbers array.

$scope.submitNumber = function(){
  $scope.numbers.push($scope.telephone);
}

This is preferred approach in most cases:

 File.open(yourfile, 'w') { |file| file.write("your text") }

When a block is passed to File.open, the File object will be automatically closed when the block terminates.

If you don't pass a block to File.open, you have to make sure that file is correctly closed and the content was written to file.

begin
  file = File.open("/tmp/some_file", "w")
  file.write("your text") 
rescue IOError => e
  #some error occur, dir not writable etc.
ensure
  file.close unless file.nil?
end

You can find it in documentation:

static VALUE rb_io_s_open(int argc, VALUE *argv, VALUE klass)
{
    VALUE io = rb_class_new_instance(argc, argv, klass);
    if (rb_block_given_p()) {
        return rb_ensure(rb_yield, io, io_close, io);
    }
    return io;
}

This works in my case. I hope you can extract meaning out of it.

//div[text()='building1' and @class='wrap']/ancestor::tr/td/div/div[@class='x-grid-row-checker']

Posting a new answer since it is (almost) 2020.

The Android Emulator still only supports HAXM or WHPX on windows. And you may even call it a day already with the latter.

But if you don't like it, there is now work in progress AMD-V support for the former by one of the PS4 emulator developers: https://github.com/jarveson/haxm/tree/svm

The most voted answer works fine except for the 1st week and last week of a year. For example, if the value of WeddingDate is '2016-01-01', the result will be 2015-12-27 and 2016-01-02, but the right answer is 2016-01-01 and 2016-01-02.

Try this:

Select 
  Sum(NumberOfBrides) As [Wedding Count], 
  DATEPART( wk, WeddingDate) as [Week Number],
  DATEPART( year, WeddingDate) as [Year],
  MAX(CASE WHEN DATEPART(WEEK, WeddingDate) = 1 THEN CAST(DATEADD(YEAR, DATEDIFF(YEAR, 0, WeddingDate), 0) AS date) ELSE DATEADD(DAY, 7 * DATEPART(WEEK, WeddingDate), DATEADD(DAY, -(DATEPART(WEEKDAY, DATEADD(YEAR, DATEDIFF(YEAR, 0, WeddingDate), 0)) + 6), DATEADD(YEAR, DATEDIFF(YEAR, 0, WeddingDate), 0))) END) as WeekStart,
  MAX(CASE WHEN DATEPART(WEEK, WeddingDate) = DATEPART(WEEK, DATEADD(DAY, -1, DATEADD(YEAR, DATEDIFF(YEAR, 0, WeddingDate) + 1, 0))) THEN DATEADD(DAY, -1, DATEADD(YEAR, DATEDIFF(YEAR, 0, WeddingDate) + 1, 0)) ELSE DATEADD(DAY, 7 * DATEPART(WEEK, WeddingDate) + 6, DATEADD(DAY, -(DATEPART(WEEKDAY, DATEADD(YEAR, DATEDIFF(YEAR, 0, WeddingDate), 0)) + 6), DATEADD(YEAR, DATEDIFF(YEAR, 0, WeddingDate), 0))) END) as WeekEnd
FROM  MemberWeddingDates
Group By DATEPART( year, WeddingDate), DATEPART( wk, WeddingDate)
Order By Sum(NumberOfBrides) Desc;

The result looks like:

It works for all weeks, 1st or others.

You need the following permissions in your manifest file:

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

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()

You'll find a nice tutorial on the subject on this site.

If you don't want to implement the listener, you can set it up like this directly where you want it (call on your spinner after your adapter has been set):

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

                switch (position) {
                    case 0:
                        Toast.makeText(parent.getContext(), "Spinner item 1!", Toast.LENGTH_SHORT).show();
                        break;
                    case 1:
                        Toast.makeText(parent.getContext(), "Spinner item 2!", Toast.LENGTH_SHORT).show();
                        break;
                    case 2:
                        Toast.makeText(parent.getContext(), "Spinner item 3!", Toast.LENGTH_SHORT).show();
                        break;
                }
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

               // sometimes you need nothing here
            }
        });

.tpl shows there is a smarty! Smarty is a template language to split out PHP code from HTML code. Which gives us to the ability to do design stuff on a page which has not included PHP code.

In C++, you can use the global function std::getline, it takes a string and a stream and an optional delimiter and reads 1 line until the delimiter specified is reached. An example:

#include <string>
#include <iostream>
#include <fstream>

int main() {
    std::ifstream input("filename.txt");
    std::string line;

    while( std::getline( input, line ) ) {
        std::cout<<line<<'\n';
    }

    return 0;
}

This program reads each line from a file and echos it to the console.

For C you're probably looking at using fgets, it has been a while since I used C, meaning I'm a bit rusty, but I believe you can use this to emulate the functionality of the above C++ program like so:

#include <stdio.h>

int main() {
    char line[1024];
    FILE *fp = fopen("filename.txt","r");

    //Checks if file is empty
    if( fp == NULL ) {                       
        return 1;
    }

    while( fgets(line,1024,fp) ) {
        printf("%s\n",line);
    }

    return 0;
}

With the limitation that the line can not be longer than the maximum length of the buffer that you're reading in to.

You can set the default authenticator for http requests like this:

Authenticator.setDefault (new Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication ("username", "password".toCharArray());
    }
});

Also, if you require more flexibility, you can check out the Apache HttpClient, which will give you more authentication options (as well as session support, etc.)

I got a different idea:

First:

pip install python-dotenv

Install the python-dotenv module, which will read local preference for your project environment.

Second:

Add .flaskenv file in your project directory. Add following code:

FLASK_ENV=development

It's done!

With this config for your Flask project, when you run flask run and you will see this output in your terminal:

And when you edit your file, just save the change. You will see auto-reload is there for you:

With more explanation:

Of course you can manually hit export FLASK_ENV=development every time you need. But using different configuration file to handle the actual working environment seems like a better solution, so I strongly recommend this method I use.

In Visual studio use all your header filer below "stdafx.h".

Note: This example uses the draft version of the Flexible Box Layout Module. It has been superseded by the incompatible modern specification.

Center the child elements of a div box by using the box-align and box-pack properties together.

Example:

div
{
width:350px;
height:100px;
border:1px solid black;

/* Internet Explorer 10 */
display:-ms-flexbox;
-ms-flex-pack:center;
-ms-flex-align:center;

/* Firefox */
display:-moz-box;
-moz-box-pack:center;
-moz-box-align:center;

/* Safari, Opera, and Chrome */
display:-webkit-box;
-webkit-box-pack:center;
-webkit-box-align:center;

/* W3C */
display:box;
box-pack:center;
box-align:center;
} 

To fully comply with RSpec ~> 3.1 syntax and rubocop-rspec's default option for rule RSpec/MessageSpies, here's what you can do with spy:

Message expectations put an example's expectation at the start, before you've invoked the code-under-test. Many developers prefer using an arrange-act-assert (or given-when-then) pattern for structuring tests. Spies are an alternate type of test double that support this pattern by allowing you to expect that a message has been received after the fact, using have_received.

# arrange.
invitation = spy('invitation')

# act.
invitation.deliver("[email protected]")

# assert.
expect(invitation).to have_received(:deliver).with("[email protected]")

If you don't use rubocop-rspec or using non-default option. You may, of course, use RSpec 3 default with expect.

dbl = double("Some Collaborator")
expect(dbl).to receive(:foo).with("[email protected]")

Having just messed around with this, it's useful to kjnow that the e.X / e.Y points are relative to the control, so if (as I was) you are adding a context menu to a listview or something similar, you will want to adjust it with the form's origin. In the example below I've added 20 to the x/y so that the menu appears slightly to the right and under the cursor.

cmDelete.Show(this, new Point(e.X + ((Control)sender).Left+20, e.Y + ((Control)sender).Top+20));

Defining array with multiple types in TypeScript

Use a union type (string|number)[] demo:

const foo: (string|number)[] = [ 1, "message" ];

I have an array of the form: [ 1, "message" ].

If you are sure that there are always only two elements [number, string] then you can declare it as a tuple:

const foo: [number, string] = [ 1, "message" ];

To make something like associative array in JavaScript you have to use objects. ?

var obj = {}; // {} will create an object
var name = "name";
var val = 2;
obj[name] = val;
console.log(obj);

DEMO: http://jsfiddle.net/bz8pK/1/

you can redirect stderr.

more explanation here, but having a command like:

MyCommand >log.txt 2>errors.txt

should grab the data you are looking for.

Also, as a trick, Windows bypasses that limitation if the path is prefixed with \\?\ (msdn)

Another trick if you have a root or destination that starts with a long path, perhaps SUBST will help:

SUBST Q: "C:\Documents and Settings\MyLoginName\My Documents\MyStuffToBeCopied"
Xcopy Q:\ "d:\Where it needs to go" /s /e
SUBST Q: /D

From reading the source code, if a java.sql.Date does actually have time information, calling getTime() will return a value that includes the time information.

If that is not working, then the information is not in the java.sql.Date object. I expect that the JDBC drivers or the database is (in effect) zeroing the time component ... or the information wasn't there in the first place.

I think you should be using java.sql.Timestamp and the corresponding resultset methods, and the corresponding SQL type.

You should include <string.h> (or its C++ equivalent, <cstring>).

On github there is also a secret way...

You can filter commits by author in the commit view by appending param ?author=github_handle. For example, the link https://github.com/dynjs/dynjs/commits/master?author=jingweno shows a list of commits to the Dynjs project

As per MSDN the default value is 4096 KB (4 MB).

UPDATE

As for the Maximum, since it is an int data type, then theoretically you can go up to 2,147,483,647. Also I wanted to make sure that you are aware that IIS 7 uses maxAllowedContentLength for specifying file upload size. By default it is set to 30000000 around 30MB and being an uint, it should theoretically allow a max of 4,294,967,295

<div id="scroller" style="height: 400px; width: 100%; overflow: auto;">
<iframe height="100%" id="iframe" scrolling="no" width="100%" src="url" />
</div>

I'm building my first site and this helped me get this working for all sites that I use iframe embededding for.

Thanks!

1. what's happening? you haven' shown much of the output to be able to decide. if you are using netbeans 7.4, try disabling Compile on Save.

2. to enable debug output, either run Custom > Goals... action from project popup or after running a regular build, click the Rerun with options action from the output's toolbar

You might get into trouble when you try to display multi-line message separated with "\r\n".

It is always a good practice to do things in a standard way, and use Environment.NewLine

Some of the other answers would have poor performance on very large arrays, because methods like removeObject: and removeObjectsInArray: involve doing a linear search of the receiver, which is a waste because you already know where the object is. Also, any call to removeObjectAtIndex: will have to copy values from the index to the end of the array up by one slot at a time.

More efficient would be the following:

NSMutableArray *array = ...
NSMutableArray *itemsToKeep = [NSMutableArray arrayWithCapacity:[array count]];
for (id object in array) {
    if (! shouldRemove(object)) {
        [itemsToKeep addObject:object];
    }
}
[array setArray:itemsToKeep];

Because we set the capacity of itemsToKeep, we don't waste any time copying values during a resize. We don't modify the array in place, so we are free to use Fast Enumeration. Using setArray: to replace the contents of array with itemsToKeep will be efficient. Depending on your code, you could even replace the last line with:

[array release];
array = [itemsToKeep retain];

So there isn't even a need to copy values, only swap a pointer.

You need to use a <br> because your Content-Type is text/html.

It works without the Content-Type header because then your e-mail will be interpreted as plain text. If you really want to use \n you should use Content-Type: text/plain but then you'll lose any markup.

I was having this problem with Android Studio when I'm behind a proxy. I was using Crashlytics that tries to upload the mapping file during a build.

I added the missing proxy certificate to the truststore located at /Users/[username]/Documents/Android Studio.app/Contents/jre/jdk/Contents/Home/jre/lib/security/cacerts

with the following command: keytool -import -trustcacerts -keystore cacerts -storepass [password] -noprompt -alias [alias] -file [my_certificate_location]

for example with the default truststore password keytool -import -trustcacerts -keystore cacerts -storepass changeit -noprompt -alias myproxycert -file /Users/myname/Downloads/MyProxy.crt

If you don't know the index, you can't use logical_and

x = 10*np.random.randn(1,100)
low = 5
high = 27
x[0,np.logical_and(x[0,:]>low,x[0,:]<high)]

torch.Tensor.view()

Simply put, torch.Tensor.view() which is inspired by numpy.ndarray.reshape() or numpy.reshape(), creates a new view of the tensor, as long as the new shape is compatible with the shape of the original tensor.

Let's understand this in detail using a concrete example.

In [43]: t = torch.arange(18) 

In [44]: t 
Out[44]: 
tensor([ 0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14, 15, 16, 17])

With this tensor t of shape (18,), new views can only be created for the following shapes:

(1, 18) or equivalently (1, -1) or (-1, 18)
(2, 9) or equivalently (2, -1) or (-1, 9)
(3, 6) or equivalently (3, -1) or (-1, 6)
(6, 3) or equivalently (6, -1) or (-1, 3)
(9, 2) or equivalently (9, -1) or (-1, 2)
(18, 1) or equivalently (18, -1) or (-1, 1)

As we can already observe from the above shape tuples, the multiplication of the elements of the shape tuple (e.g. 2*9, 3*6 etc.) must always be equal to the total number of elements in the original tensor (18 in our example).

Another thing to observe is that we used a -1 in one of the places in each of the shape tuples. By using a -1, we are being lazy in doing the computation ourselves and rather delegate the task to PyTorch to do calculation of that value for the shape when it creates the new view. One important thing to note is that we can only use a single -1 in the shape tuple. The remaining values should be explicitly supplied by us. Else PyTorch will complain by throwing a RuntimeError:

RuntimeError: only one dimension can be inferred

So, with all of the above mentioned shapes, PyTorch will always return a new view of the original tensor t. This basically means that it just changes the stride information of the tensor for each of the new views that are requested.

Below are some examples illustrating how the strides of the tensors are changed with each new view.

# stride of our original tensor `t`
In [53]: t.stride() 
Out[53]: (1,)

Now, we will see the strides for the new views:

# shape (1, 18)
In [54]: t1 = t.view(1, -1)
# stride tensor `t1` with shape (1, 18)
In [55]: t1.stride() 
Out[55]: (18, 1)

# shape (2, 9)
In [56]: t2 = t.view(2, -1)
# stride of tensor `t2` with shape (2, 9)
In [57]: t2.stride()       
Out[57]: (9, 1)

# shape (3, 6)
In [59]: t3 = t.view(3, -1) 
# stride of tensor `t3` with shape (3, 6)
In [60]: t3.stride() 
Out[60]: (6, 1)

# shape (6, 3)
In [62]: t4 = t.view(6,-1)
# stride of tensor `t4` with shape (6, 3)
In [63]: t4.stride() 
Out[63]: (3, 1)

# shape (9, 2)
In [65]: t5 = t.view(9, -1) 
# stride of tensor `t5` with shape (9, 2)
In [66]: t5.stride()
Out[66]: (2, 1)

# shape (18, 1)
In [68]: t6 = t.view(18, -1)
# stride of tensor `t6` with shape (18, 1)
In [69]: t6.stride()
Out[69]: (1, 1)

So that's the magic of the view() function. It just changes the strides of the (original) tensor for each of the new views, as long as the shape of the new view is compatible with the original shape.

Another interesting thing one might observe from the strides tuples is that the value of the element in the 0^th position is equal to the value of the element in the 1^st position of the shape tuple.

In [74]: t3.shape 
Out[74]: torch.Size([3, 6])
                        |
In [75]: t3.stride()    |
Out[75]: (6, 1)         |
          |_____________|

This is because:

In [76]: t3 
Out[76]: 
tensor([[ 0,  1,  2,  3,  4,  5],
        [ 6,  7,  8,  9, 10, 11],
        [12, 13, 14, 15, 16, 17]])

the stride (6, 1) says that to go from one element to the next element along the 0^th dimension, we have to jump or take 6 steps. (i.e. to go from 0 to 6, one has to take 6 steps.) But to go from one element to the next element in the 1^st dimension, we just need only one step (for e.g. to go from 2 to 3).

Thus, the strides information is at the heart of how the elements are accessed from memory for performing the computation.

torch.reshape()

This function would return a view and is exactly the same as using torch.Tensor.view() as long as the new shape is compatible with the shape of the original tensor. Otherwise, it will return a copy.

However, the notes of torch.reshape() warns that:

contiguous inputs and inputs with compatible strides can be reshaped without copying, but one should not depend on the copying vs. viewing behavior.

You can use a FormData object which is safe and fast:

// Store the file object when input field is changed
$scope.contentChanged = function(event){
    if (!event.files.length)
        return null;

    $scope.content = new FormData();
    $scope.content.append('fileUpload', event.files[0]); 
    $scope.$apply();
}

// Upload the file over HTTP
$scope.upload = function(){
    $http({
        method: 'POST', 
        url: '/remote/url',
        headers: {'Content-Type': undefined },
        data: $scope.content,
    }).success(function(response) {
        // Uploading complete
        console.log('Request finished', response);
    });
}

From this document, this DTU percent is determined by this query:

SELECT end_time,   
  (SELECT Max(v)    
   FROM (VALUES (avg_cpu_percent), (avg_data_io_percent), 
(avg_log_write_percent)) AS    
   value(v)) AS [avg_DTU_percent]   
FROM sys.dm_db_resource_stats;  

looks like the max of avg_cpu_percent, avg_data_io_percent and avg_log_write_percent

TL;DR

You want this:

AAPL:
  - shares: -75.088
    date: 11/27/2015
  - shares: 75.088
    date: 11/26/2015

Mappings

The YAML equivalent of a JSON object is a mapping, which looks like these:

# flow style
{ foo: 1, bar: 2 }

# block style
foo: 1
bar: 2

Note that the first characters of the keys in a block mapping must be in the same column. To demonstrate:

# OK
   foo: 1
   bar: 2

# Parse error
   foo: 1
    bar: 2

Sequences

The equivalent of a JSON array in YAML is a sequence, which looks like either of these (which are equivalent):

# flow style
[ foo bar, baz ]

# block style
- foo bar
- baz

In a block sequence the -s must be in the same column.

JSON to YAML

Let's turn your JSON into YAML. Here's your JSON:

{"AAPL": [
  {
    "shares": -75.088,
    "date": "11/27/2015"
  },
  {
    "shares": 75.088,
    "date": "11/26/2015"
  },
]}

As a point of trivia, YAML is a superset of JSON, so the above is already valid YAML—but let's actually use YAML's features to make this prettier.

Starting from the inside out, we have objects that look like this:

{
  "shares": -75.088,
  "date": "11/27/2015"
}

The equivalent YAML mapping is:

shares: -75.088
date: 11/27/2015

We have two of these in an array (sequence):

- shares: -75.088
  date: 11/27/2015
- shares: 75.088
  date: 11/26/2015

Note how the -s line up and the first characters of the mapping keys line up.

Finally, this sequence is itself a value in a mapping with the key AAPL:

AAPL:
  - shares: -75.088
    date: 11/27/2015
  - shares: 75.088
    date: 11/26/2015

Parsing this and converting it back to JSON yields the expected result:

{
  "AAPL": [
    {
      "date": "11/27/2015", 
      "shares": -75.088
    }, 
    {
      "date": "11/26/2015", 
      "shares": 75.088
    }
  ]
}

You can see it (and edit it interactively) here.

Nowadays - using C++11 - you can use enum class for this:

enum class Color { RED, BLUE, WHITE };

AFAII this does exactly what you want.

This is probably the least technical answer to the question, but it's also the easiest to accomplish.

If you have two drives such as C: and D: you can install a separate instance of XAMPP on both drives with different php versions. This took me less than 10 mins to do and is least error prone.

I just create two desktop shortcuts to both xampp-control.exe and name the shortcuts after their php version. I hope this helps someone like me that prefers a very quick and dirty solution.

Example:

ALTER TABLE [Employees] ADD Seniority int not null default 0 GO

If you can't go over your time limit (it's a hard limit) then a thread is your best bet. You can use a loop to terminate the thread once you get to the time threshold. Whatever is going on in that thread at the time can be interrupted, allowing calculations to stop almost instantly. Here is an example:

Thread t = new Thread(myRunnable); // myRunnable does your calculations

long startTime = System.currentTimeMillis();
long endTime = startTime + 60000L;

t.start(); // Kick off calculations

while (System.currentTimeMillis() < endTime) {
    // Still within time theshold, wait a little longer
    try {
         Thread.sleep(500L);  // Sleep 1/2 second
    } catch (InterruptedException e) {
         // Someone woke us up during sleep, that's OK
    }
}

t.interrupt();  // Tell the thread to stop
t.join();       // Wait for the thread to cleanup and finish

That will give you resolution to about 1/2 second. By polling more often in the while loop, you can get that down.

Your runnable's run would look something like this:

public void run() {
    while (true) {
        try {
            // Long running work
            calculateMassOfUniverse();
        } catch (InterruptedException e) {
            // We were signaled, clean things up
            cleanupStuff();
            break;           // Leave the loop, thread will exit
    }
}

Update based on Dmitri's answer

Dmitri pointed out TimerTask, which would let you avoid the loop. You could just do the join call and the TimerTask you setup would take care of interrupting the thread. This would let you get more exact resolution without having to poll in a loop.

If you are using the background image for the rounded corners then I would rather increase the padding style of the main div to give enough room for the rounded corners of the background image to be visible.

Try increasing the padding of the main div style:

#mainWrapperDivWithBGImage 
{   
    background: url("myImageWithRoundedCorners.jpg") no-repeat scroll 0 0 transparent;   
    height: 248px;   
    margin: 0;   
    overflow: hidden;   
    padding: 10px 10px;   
    width: 996px; 
}

P.S: I assume the rounded corners have a radius of 10px.
