Enabling [x] Use temporary JAR to specify classpath (to avoid classpath length limitations) inside the Classpath tab of the Run configuration did the trick for me.

If your project is huge and you have lots of dependencies from other sibling projects and maven dependencies, you might hit the classpath length limitations and this seems to be the only solution (apart from making the directory to you local maven repo shorter (ours already starts at c:/m2)

Do you want [classname] to be 'one' and [objectname] to be 'A'?

If so, this is not possible. These names are only abstractions for the programmer, and aren't actually used in the binary code that is generated. You could give the class a static variable classname, which you set to 'one' and a normal variable objectname which you would assign either directly, through a method or the constructor. You can then query these methods for the class and object names.

In Ubuntu-Gnome, simply pressing CTRL+L should clear the screen.

This also seems to also work well in Windows 10 and 7 and Mac OS X Sierra.

To produce key events without Windows Forms Context, We can use the following method,

[DllImport("user32.dll")]
public static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, uint dwExtraInfo);

sample code is given below:

const int VK_UP = 0x26; //up key
const int VK_DOWN = 0x28;  //down key
const int VK_LEFT = 0x25;
const int VK_RIGHT = 0x27;
const uint KEYEVENTF_KEYUP = 0x0002;
const uint KEYEVENTF_EXTENDEDKEY = 0x0001;
int press()
{
    //Press the key
    keybd_event((byte)VK_UP, 0, KEYEVENTF_EXTENDEDKEY | 0, 0);
    return 0;
}

List of Virtual Keys are defined here.

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

Figured it out, folks! for the NAME of the text box, you have to use "q". I had "g" just for my own personal preferences. But apparently it has to be "q".

Anyone know why?

var path = document.getElementById('upload').value;//take path
var tokens= path.split('\\');//split path
var filename = tokens[tokens.length-1];//take file name

Octave is basically an open source version of MATLAB. It was written to be just that. MATLAB has a very nice GUI which makes it a bit easier to use but the next stable release of OCTAVE will also have a GUI, which I have tested in the unstable release, and looks fantastic. Octave is much more buggy because it was developed and maintained by a group of volunteers, where the development of MATLAB is funded by millions of dollars by industry. I'm still a student and am using a student version of MATLAB, but I am thinking of going over to Octave once the stable version with the GUI is released.

MATLAB is probably a lot more powerful than Octave, and the algorithms run faster, but for most applications, Octave is more than adequate and is, in my opinion' an amazing tool that is completely free, where Octave is completely free.

I would say use MATLAB while you can use the academic version, but the switch to Octave should be seamless as they use the exact same syntax.

Lastly, there is the issue of SIMULINK. If you want to do simulation or control system design (there are probably a million other uses) SIMULINK is fantastic and comes with MATLAB. I don't think any other comes close to this, although Scilab is apparently a 'good' open source alternative, I haven't tried it.

Peace.

declare @newdata varchar(30)
set @newdata='IDS_ENUM_Change_262147_190'
select REVERSE(substring(reverse(@newdata),0,charindex('_',reverse(@newdata))))

=== Explanation ===

I found it easier to read written like this:

SELECT
    REVERSE( --4.
        SUBSTRING( -- 3.
            REVERSE(<field_name>),
            0,
            CHARINDEX( -- 2.
                '<your char of choice>',
                REVERSE(<field_name>) -- 1.
            )
        )
    )
FROM
    <table_name>

1. Reverse the text
2. Look for the first occurrence of a specif char (i.e. first occurrence FROM END of text). Gets the index of this char
3. Looks at the reversed text again. searches from index 0 to index of your char. This gives the string you are looking for, but in reverse
4. Reversed the reversed string to give you your desired substring

In swift3 you can easily remove optional

if let value = optionalvariable{
 //in value you will get non optional value
}

In .Net core 3.1 you can try like this

d?.value2 , d?.value3

.cmd and .bat file execution is different because in a .cmd errorlevel variable it can change on a command that is affected by command extensions. That's about it really.

You can use IETester (http://www.my-debugbar.com/wiki/IETester/HomePage)

I disabled all installed extensions in Chrome - works for me. I have now clear console without errors.

An ultimate solution would be to embed a simple http server listening on your 'secret' port on loopback. Then you can substitute the matched image src URL with something like http://localhost:123/.../mypic.jpg

Java's regular expressions don't require you to put a forward-slash (/) or any other delimiter around the regex, as opposed to other languages like Perl, for example.

Use stmt.setDate(1, new java.sql.Date(cal.getTimeInMillis()))

Or you might be looking at this question because you happened to make a silly typo like I did and have the =~ reversed to ~=

You can try importing them and then handle the ImportError if the module doesn't exist.

try:
    import numpy
except ImportError:
    print "numpy is not installed"

The easiest way is to use position: fixed:

.element {
  position: fixed;
  bottom: 0;
  right: 0;
}

http://www.w3.org/TR/CSS21/visuren.html#choose-position

(note that position fixed is buggy / doesn't work on ios and android browsers)

I tried so many different things and finally found what worked best for me was simply adding in padding-right: 28px;

I played around with the padding to get the right amount to evenly space the items.

Couldn't get bootstrap datepicker to work until I wrap the textbox with position relative element as shown here:

<span style="position: relative">
 <input  type="text" placeholder="click to show datepicker"  id="pickyDate"/>
</span>

Coversion from string to double can be achieved by using the 'strtod()' function from the library 'stdlib.h'

#include <iostream>
#include <stdlib.h>
int main () 
{
    std::string data="20.9";
    double value = strtod(data.c_str(), NULL);
    std::cout<<value<<'\n';
    return 0;
}

You need to enclose that in <%! %> as follows:

<%!

public String getQuarter(int i){
String quarter;
switch(i){
        case 1: quarter = "Winter";
        break;

        case 2: quarter = "Spring";
        break;

        case 3: quarter = "Summer I";
        break;

        case 4: quarter = "Summer II";
        break;

        case 5: quarter = "Fall";
        break;

        default: quarter = "ERROR";
}

return quarter;
}

%>

You can then invoke the function within scriptlets or expressions:

<%
     out.print(getQuarter(4));
%>

or

<%= getQuarter(17) %>

Use the substring() function with an argument of 1 to get the substring from position 1 (after the first character) to the end of the string (leaving the second argument out defaults to the full length of the string).

"Jamaica".substring(1);

Try this:

npm --depth 9999 update
npm rebuild node-sass

I also faced the same issue but in VS2013.

I did the below way to fix, It was worked fine.

1. Close all the opened Visual studio instance.

2. Then, go to "Developer command prompt" from visual studio tools,

3. Type it as devenv.exe /resetuserdata

4. Restart the machine, Open the Visual studio then It will ask you to choose the development settings from initial onwards, thereafter open any solution/project. You'll be amazed.

Hope, it might helps you :)

in gradle.properties, you can even delete

org.gradle.jvmargs=-Xmx1536m

such lines or comment them out. Let android studio decide for it. When I ran into this same problem, none of above solutions worked for me. Commenting out this line in gradle.properties helped in solving that error.

var data = fs.readFileSync('tmp/reltioconfig.json','utf8');

use this for calling a file synchronously, without encoding its showing output as a buffer.

Have you done what @Teddy recommended and you STILL get the same error?

Make sure you're changing the settings for the app pool that corresponds to your virtual directory and not the parent server. Each virtual directory has its own AppPool and doesn't inherit.

Here is an answer by way of example:

In order to make sure data loggers are online a cron script runs every 15 minutes that looks like this:

#!/bin/bash
#
if ! ping -c 1 SOLAR &>/dev/null
then
  echo "SUBJECT:  SOLAR is not responding to ping" | ssmtp [email protected]
  echo "SOLAR is not responding to ping" | ssmtp [email protected]
else
  echo "SOLAR is up"
fi
#
if ! ping -c 1 OUTSIDE &>/dev/null
then
  echo "SUBJECT:  OUTSIDE is not responding to ping" | ssmtp [email protected]
  echo "OUTSIDE is not responding to ping" | ssmtp [email protected]
else
  echo "OUTSIDE is up"
fi
#

...and so on for each data logger that you can see in the montage at http://www.SDsolarBlog.com/montage

FYI, using &>/dev/null redirects all output from the command, including errors, to /dev/null

(The conditional only requires the exit status of the ping command)

Also FYI, note that since cron jobs run as root there is no need to use sudo ping in a cron script.

If id is sequential starting at 1, the simplest (and quickest) would be:

UPDATE `table` 
SET uid = ELT(id, 2952, 4925, 1592) 
WHERE id IN (1,2,3)

As ELT() returns the Nth element of the list of strings: str1 if N = 1, str2 if N = 2, and so on. Returns NULL if N is less than 1 or greater than the number of arguments.

Clearly, the above code only works if id is 1, 2, or 3. If id was 10, 20, or 30, either of the following would work:

UPDATE `table` 
SET uid = CASE id 
WHEN 10 THEN 2952 
WHEN 20 THEN 4925 
WHEN 30 THEN 1592 END CASE 
WHERE id IN (10, 20, 30)

or the simpler:

UPDATE `table` 
SET uid = ELT(FIELD(id, 10, 20, 30), 2952, 4925, 1592) 
WHERE id IN (10, 20, 30)

As FIELD() returns the index (position) of str in the str1, str2, str3, ... list. Returns 0 if str is not found.

$time = date("H:i", strtotime($today . " +5 hours +30 minutes"));
//+5 hours +30 minutes     Time Zone +5:30 (Asia/Kolkata)

You can use CTE to get the distinct values of the second table, and then join that with the first table. You also need to get the distinct values based on LastName column. You do this with a Row_Number() partitioned by the LastName, and sorted by the FirstName.

Here's the code

;WITH SecondTableWithDistinctLastName AS
(
        SELECT  *
        FROM    (
                    SELECT  *,
                            ROW_NUMBER() OVER (PARTITION BY LastName ORDER BY FirstName) AS [Rank]
                    FROM    AddTbl
                )   
        AS      tableWithRank
        WHERE   tableWithRank.[Rank] = 1
) 
SELECT          a.FirstName, a.LastName, S.District
FROM            SecondTableWithDistinctLastName AS S
INNER JOIN      AddTbl AS a
    ON          a.LastName = S.LastName
ORDER   BY      a.FirstName

Common Lisp

I would add "Practical Common Lisp", by Peter Seibel to the lisp list. It is particularly good at providing examples (MP3 parsing, shoutcast server, HTML compiler) that are topical.

http://gigamonkeys.com/book/

Use String#strip

Returns a copy of str with leading and trailing whitespace removed.

e.g

"    hello    ".strip   #=> "hello"   
"\tgoodbye\r\n".strip   #=> "goodbye"

Using gsub

string = string.gsub(/\r/," ")
string = string.gsub(/\n/," ")

When using Typescript:

In my case I used the newer syntax of webpack v3.11 from their documentation page I just copied the css and style loaders configuration form their website. The commented out code (newer API) causes this error, see below.

  module: {
        loaders: [{
                test: /\.ts$/,
                loaders: ['ts-loader']
            },
            {
                test: /\.css$/,
                loaders: [
                    'style-loader',
                    'css-loader'
                ]
            }
        ]
        // ,
        // rules: [{
        //     test: /\.css$/,
        //     use: [
        //         'style-loader',
        //         'css-loader'
        //     ]
        // }]
    }

The right way is to put this:

    {
        test: /\.css$/,
        loaders: [
            'style-loader',
            'css-loader'
        ]
    }

in the array of the loaders property.

As @Richard pointed out above, the onClick needs to have a capital 'C'.

$('#stop').click(function() {
     $('next').attr('onClick','stopMoving()');
}

The question comes down to what you're going to do with the files.

Under Windows, any directory with more than 2k files tends to open slowly for me in Explorer. If they're all image files, more than 1k tend to open very slowly in thumbnail view.

At one time, the system-imposed limit was 32,767. It's higher now, but even that is way too many files to handle at one time under most circumstances.

You could possibly use this and use jQuery to update the css height of the elements to make sure it stays in place.

Installing Java Cryptography Extension (JCE) Unlimited Strength (for JDK7 | for JDK8) might fix this bug. Unzip the file and follow the readme to install it.

If you want to grab the 'value' attribute instead of the text node, this will work for you:

var conceptName = $('#aioConceptName').find(":selected").attr('value');

In general, you're better off validating URLs using built-in library or framework functions, rather than rolling your own regular expressions to do this - see What is the best regular expression to check if a string is a valid URL for details.

If you are keen on doing this, though, check out this question:

Getting parts of a URL (Regex)

Then, once you're satisfied with the URL (by whatever means you used to validate it), you could either use a simple "endswith" type string operator to check the extension, or a simple regex like

(?i)\.(jpg|png|gif)$

I've found out the solution! Thanks to Firebug ;)

//"markers" is an array that I declared which contains all the marker of the map
//"i" is the index of the marker in the array that I want to trigger the OnClick event

//V2 version is:
GEvent.trigger(markers[i], 'click');

//V3 version is:
google.maps.event.trigger(markers[i], 'click');

you can render the page in express more easily

 var app   = require('express')();    
    app.set('views', path.join(__dirname, 'views'));
    app.set('view engine', 'jade');
 
    app.get('/signup',function(req,res){      
    res.sendFile(path.join(__dirname,'/signup.html'));
    });

so if u request like http://127.0.0.1:8080/signup that it will render signup.html page under views folder.

SELECT * FROM a WHERE a.group_id IN 
(SELECT group_id FROM b WHERE b.user_id!=$_SESSION{'[user_id']} AND b.group_id = a.group_id)
WHERE a.keyword LIKE '%".$keyword."%';

Write below code in script and also add jQuery library

var getElement = document.getElementById('myID');

if (document.activeElement === getElement) {
        $(document).keydown(function(event) {
            if (event.which === 40) {
                console.log('keydown pressed')
            }
        });
    }

LIBRARY_PATH is used by gcc before compilation to search directories containing static and shared libraries that need to be linked to your program.

LD_LIBRARY_PATH is used by your program to search directories containing shared libraries after it has been successfully compiled and linked.

EDIT: As pointed below, your libraries can be static or shared. If it is static then the code is copied over into your program and you don't need to search for the library after your program is compiled and linked. If your library is shared then it needs to be dynamically linked to your program and that's when LD_LIBRARY_PATH comes into play.

PHP Manual says:

gethostname (PHP >= 5.3.0) gethostname — Gets the host name

Look:

echo php_uname('n'); // may output e.g,: sandie
?>

Can be

x => x.Lists.Include(l => l.Title)
     .Where(l => l.Title != String.Empty && l.InternalName != String.Empty)

or

x => x.Lists.Include(l => l.Title)
     .Where(l => l.Title != String.Empty)
     .Where(l => l.InternalName != String.Empty)

When you are looking at Where implementation, you can see it accepts a Func(T, bool); that means:

• T is your IEnumerable type
• bool means it needs to return a boolean value

So, when you do

.Where(l => l.InternalName != String.Empty)
//     ^                   ^---------- boolean part
//     |------------------------------ "T" part

So all of the "try to rewrite without an exception" solution in this page has a minor problem. Either its not throwing NonUnique exception, nor throw it in some wrong cases too (see below).

I think the proper solution is (maybe) this:

public static <L> L getSingleResultOrNull(TypedQuery<L> query) {
    List<L> results = query.getResultList();
    L foundEntity = null;
    if(!results.isEmpty()) {
        foundEntity = results.get(0);
    }
    if(results.size() > 1) {
        for(L result : results) {
            if(result != foundEntity) {
                throw new NonUniqueResultException();
            }
        }
    }
    return foundEntity;
}

Its returning with null if there is 0 element in the list, returning nonunique if there are different elements in the list, but not returning nonunique when one of your select is not properly designed and returns the same object more then one times.

Feel free to comment.

To combine both Nitzan's and Edwin's answers, I found that something like this works for me:

update = (e: React.FormEvent<EventTarget>): void => {
    let target = e.target as HTMLInputElement;
    this.props.login[target.name] = target.value;
}

Use it like this:

if (lbl.Text.StartWith("hr")==true ) {…}

This is a three liner. Just follow the instructions on the boto3 documentation.

import boto3
s3 = boto3.resource(service_name = 's3')
s3.meta.client.upload_file(Filename = 'C:/foo/bar/baz.filetype', Bucket = 'yourbucketname', Key = 'baz.filetype')

Some important arguments are:

Parameters:

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

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

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

Demo: Fiddle

Another possible solution specially if you want batch delete

deleted_objects = User.__table__.delete().where(User.id.in_([1, 2, 3]))
session.execute(deleted_objects)
session.commit()

In all of the above, the EditText still needs the focusable="false" attribute in the xml in order to prevent the keyboard from popping up.

As many other pointed out, arguments contains all the arguments passed to a function.

If you want to call another function with the same args, use apply

Example:

var is_debug = true;
var debug = function() {
  if (is_debug) {
    console.log.apply(console, arguments);
  }
}

debug("message", "another argument")

There could many causes to this problems

What I have experienced are:
1) 127.0.0.1 localhost entry was duplicated in hosts file
2) Apache mod_rewrite was not enabled

Regardless of the cause, backing up your www folder, vhost configuration file (and httpd configuration file) will help. And such process takes a few minutes.

Good luck

If the Data-set size is less the 25mb, The easiest way to upload a CSV file is from your GitHub repository.

1. Click on the data set in the repository
2. Click on View Raw button
3. Copy the link and store it in a variable
4. load the variable into Pandas read_csv to get the dataframe

Example:

import pandas as pd
url = 'copied_raw_data_link'
df1 = pd.read_csv(url)
df1.head()

In some cases no "No module ..." can appear even on local files. In such cases you just need to mark appropriate directories as "source directories":

You are close to the solution, just getting the wrong object. It should be like this:

jQuery(function() {
    var dlg = jQuery("#dialog").dialog({
                         draggable: true,
                         resizable: true,
                         show: 'Transfer',
                         hide: 'Transfer',
                         width: 320,
                         autoOpen: false,
                         minHeight: 10,
                         minwidth: 10
                     });
    dlg.parent().appendTo(jQuery("form:first"));
});

Read about request objects that your views receive: https://docs.djangoproject.com/en/dev/ref/request-response/#httprequest-objects

Also your hidden field needs a reliable name and then a value:

<input type="hidden" name="title" value="{{ source.title }}">

Then in a view:

request.POST.get("title", "")

With Relaxed JSON, you can have trailing commas, or just leave the commas out. They are optional.

There is no reason at all commas need to be present to parse a JSON-like document.

Take a look at the Relaxed JSON spec and you will see how 'noisy' the original JSON spec is. Way too many commas and quotes...

http://www.relaxedjson.org

You can also try out your example using this online RJSON parser and see it get parsed correctly.

http://www.relaxedjson.org/docs/converter.html?source=%5B0%2C1%2C2%2C3%2C4%2C5%2C%5D

For some reason, the above answer did not work for me; I did not return to the command prompt after running it as I expected with the trailing &. Instead, I simply tried with

nohup some_command > nohup2.out&

and it works just as I want it to. Leaving this here in case someone else is in the same situation. Running Bash 4.3.8 for reference.

OK I am using the wrong syntax, I should be using

Allow from 127.0.0.1
Allow from ::1

You can pass in the hostname as an environment variable. You could also mount /etc so you can cat /etc/hostname. But I agree with Vitaly, this isn't the intended use case for containers IMO.

You can reset the entire form with:

$("#myform")[0].reset();

Or just the specific field with:

$('#form-id').children('input').val('')

<input type="button" value="Submit" id="btnsubmit" onclick="submitForm()">

function submitForm() {
   // Get the first form with the name
   // Hopefully there is only one, but there are more, select the correct index
   var frm = document.getElementsByName('contact-form')[0];
   frm.submit(); // Submit
   frm.reset();  // Reset
   return false; // Prevent page refresh
}

1) check if service declaration in manifest is nested in application tag

<application>
    <service android:name="" />
</application>

2) check if your service.java is in the same package or diff package as the activity

<application>
    <!-- service.java exists in diff package -->
    <service android:name="com.package.helper.service" /> 
</application>

<application>
    <!-- service.java exists in same package -->
    <service android:name=".service" /> 
</application>

I wanted to have something simpler for my users, the way Google does it..

function prettyOffset($offset) {

    $offset_formatted = gmdate( 'H:i', abs($offset) );

    $pretty_offset = "UTC${offset_prefix}${offset_formatted}";

    return $pretty_offset;
}

foreach ($timezones as $k => $v) {
    $tz = DateTimeZone::listIdentifiers(DateTimeZone::PER_COUNTRY, $k);

    foreach ($tz as $value) {
        $t = new DateTimeZone($value);
        $offset = (new DateTime("now", $t))->getOffset();

This gives me an array grouped by countries:

Which means now I can do something like below (of course with some javaScript trickery):

import pyaudio
import wave
from array import array

FORMAT=pyaudio.paInt16
CHANNELS=2
RATE=44100
CHUNK=1024
RECORD_SECONDS=15
FILE_NAME="RECORDING.wav"

audio=pyaudio.PyAudio() #instantiate the pyaudio

#recording prerequisites
stream=audio.open(format=FORMAT,channels=CHANNELS, 
                  rate=RATE,
                  input=True,
                  frames_per_buffer=CHUNK)

#starting recording
frames=[]

for i in range(0,int(RATE/CHUNK*RECORD_SECONDS)):
    data=stream.read(CHUNK)
    data_chunk=array('h',data)
    vol=max(data_chunk)
    if(vol>=500):
        print("something said")
        frames.append(data)
    else:
        print("nothing")
    print("\n")


#end of recording
stream.stop_stream()
stream.close()

wavfile.setsampwidth(audio.get_sample_size(FORMAT))
wavfile.setframerate(RATE)
wavfile.writeframes(b''.join(frames))#append frames recorded to file
wavfile.close()

I think this will help.It is a simple script which will check if there is a silence or not.If silence is detected it will not record otherwise it will record.

Taking Six' answer I think we could simplify somehow, an important issue as newcomers are lost in highly technical matters.

Here what I finally will use to wait for my connection (3G, slow) to be established once a day for my PV monitoring.

Works under Pyth3 with Raspbian 3.4.2

from urllib.request import urlopen
from time import sleep
urltotest=http://www.lsdx.eu             # my own web page
nboftrials=0
answer='NO'
while answer=='NO' and nboftrials<10:
    try:
        urlopen(urltotest)
        answer='YES'
    except:
        essai='NO'
        nboftrials+=1
        sleep(30)       

maximum running: 5 minutes if reached I will try in one hour's time but its another bit of script!

The keydown event will work fine for Escape and has the benefit of allowing you to use keyCode in all browsers. Also, you need to attach the listener to document rather than the body.

Update May 2016

keyCode is now in the process of being deprecated and most modern browsers offer the key property now, although you'll still need a fallback for decent browser support for now (at time of writing the current releases of Chrome and Safari don't support it).

Update September 2018 evt.key is now supported by all modern browsers.

document.onkeydown = function(evt) {_x000D_
    evt = evt || window.event;_x000D_
    var isEscape = false;_x000D_
    if ("key" in evt) {_x000D_
        isEscape = (evt.key === "Escape" || evt.key === "Esc");_x000D_
    } else {_x000D_
        isEscape = (evt.keyCode === 27);_x000D_
    }_x000D_
    if (isEscape) {_x000D_
        alert("Escape");_x000D_
    }_x000D_
};

Click me then press the Escape key

While the accepted and most upvoted answer is great, I additionally find it useful trying to explain the difference only by words:

merge

• “okay, we got two differently developed states of our repository. Let's merge them together. Two parents, one resulting child.”

rebase

• “Give the changes of the main branch (whatever its name) to my feature branch. Do so by pretending my feature work started later, in fact on the current state of the main branch.”
• “Rewrite the history of my changes to reflect that.” (need to force-push them, because normally versioning is all about not tampering with given history)
• “Likely —if the changes I raked in have little to do with my work— history actually won't change much, if I look at my commits diff by diff (you may also think of ‘patches’).“

summary: When possible, rebase is almost always better. Making re-integration into the main branch easier.

Because? ? your feature work can be presented as one big ‘patch file’ (aka diff) in respect to the main branch, not having to ‘explain’ multiple parents: At least two, coming from one merge, but likely many more, if there were several merges. Unlike merges, multiple rebases do not add up. (another big plus)

Inside your config folder you can create a php file name it for example "variable.php" with content below:

<?php

  return [
    'versionNumber' => '122231',
  ];

Now inside all the views you can use it like

config('variable.versionNumber')

This is how I got it to work cross browser using a combination of the methods above (I also needed to insert images dynamically into the dom):

$('#domTarget').html('<img src="" />');

var url = '/some/image/path.png';

$('#domTarget img').load(function(){}).attr('src', url).error(function() {
    if ( isIE ) {
       var thisImg = this;
       setTimeout(function() {
          if ( ! thisImg.complete ) {
             $(thisImg).attr('src', '/web/css/img/picture-broken-url.png');
          }
       },250);
    } else {
       $(this).attr('src', '/web/css/img/picture-broken-url.png');
    }
});

Note: You will need to supply a valid boolean state for the isIE variable.

UPDATED with latest official NuGet documentation as of v3.3.0

Package Restore Approaches

NuGet offers three approaches to using package restore.

Automatic Package Restore is the NuGet team's recommended approach to Package Restore within Visual Studio, and it was introduced in NuGet 2.7. Beginning with NuGet 2.7, the NuGet Visual Studio extension integrates into Visual Studio's build events and restores missing packages when a build begins. This feature is enabled by default, but developers can opt out if desired.

Here's how it works:

1. On project or solution build, Visual Studio raises an event that a build is beginning within the solution.
2. NuGet responds to this event and checks for packages.config files included in the solution.
3. For each packages.config file found, its packages are enumerated and Checked for exists in the solution's packages folder.
4. Any missing packages are downloaded from the user's configured (and enabled) package sources, respecting the order of the package sources.
5. As packages are downloaded, they are unzipped into the solution's packages folder.

If you have Nuget 2.7+ installed; it's important to pick one method for > managing Automatic Package Restore in Visual Studio.

Two methods are available:

1. (Nuget 2.7+): Visual Studio -> Tools -> Package Manager -> Package Manager Settings -> Enable Automatic Package Restore
2. (Nuget 2.6 and below) Right clicking on a solution and clicking "Enable Package Restore for this solution".

Command-Line Package Restore is required when building a solution from the command-line; it was introduced in early versions of NuGet, but was improved in NuGet 2.7.

nuget.exe restore contoso.sln

The MSBuild-integrated package restore approach is the original Package Restore implementation and though it continues to work in many scenarios, it does not cover the full set of scenarios addressed by the other two approaches.

While jkp's solution works, the newer way of doing things (and the way the documentation recommends) is to use the subprocess module. For simple commands its equivalent, but it offers more options if you want to do something complicated.

Example for your case:

import subprocess
subprocess.Popen(["rm","-r","some.file"])

This will run rm -r some.file in the background. Note that calling .communicate() on the object returned from Popen will block until it completes, so don't do that if you want it to run in the background:

import subprocess
ls_output=subprocess.Popen(["sleep", "30"])
ls_output.communicate()  # Will block for 30 seconds

See the documentation here.

Also, a point of clarification: "Background" as you use it here is purely a shell concept; technically, what you mean is that you want to spawn a process without blocking while you wait for it to complete. However, I've used "background" here to refer to shell-background-like behavior.

Just close the Netbeans. Go to C:\Users\YOUR_PC_NAME\AppData\Local\Netbeans and delete the Cache folder. The open the Netbeans again and run the project. It works like magic for me.

(AppData folder might be hidden probably, if so, you need to make it appear in Folder Options).

Updated Answer:

DynamoDB allows for specification of secondary indexes to aid in this sort of query. Secondary indexes can either be global, meaning that the index spans the whole table across hash keys, or local meaning that the index would exist within each hash key partition, thus requiring the hash key to also be specified when making the query.

For the use case in this question, you would want to use a global secondary index on the "CreatedAt" field.

For more on DynamoDB secondary indexes see the secondary index documentation

Original Answer:

DynamoDB does not allow indexed lookups on the range key only. The hash key is required such that the service knows which partition to look in to find the data.

You can of course perform a scan operation to filter by the date value, however this would require a full table scan, so it is not ideal.

If you need to perform an indexed lookup of records by time across multiple primary keys, DynamoDB might not be the ideal service for you to use, or you might need to utilize a separate table (either in DynamoDB or a relational store) to store item metadata that you can perform an indexed lookup against.

It is easier to get a stack trace on Firefox than it is on IE but fundamentally here is what you want to do:

Wrap the "problematic" piece of code in a try/catch block:

try {
    // some code that doesn't work
    var t = null;
    var n = t.not_a_value;
}
    catch(e) {
}

If you will examine the contents of the "error" object it contains the following fields:

e.fileName : The source file / page where the issue came from e.lineNumber : The line number in the file/page where the issue arose e.message : A simple message describing what type of error took place e.name : The type of error that took place, in the example above it should be 'TypeError' e.stack : Contains the stack trace that caused the exception

I hope this helps you out.

The keypress event from jQuery is meant to do this sort of work. You can trigger the event by passing a string "keypress" to .trigger(). However to be more specific you can actually pass a jQuery.Event object (specify the type as "keypress") as well and provide any properties you want such as the keycode being the spacebar.

http://docs.jquery.com/Events/trigger#eventdata

Read the above documentation for more details.

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

Here is the code for the short version of if-then-else statement:

( [ $a -eq 1 ] || [ $b -eq 2 ] ) && echo "ok" || echo "nok"

Pay attention to the following:

1. || and && operands inside if condition (i.e. between round parentheses) are logical operands (or/and)

2. || and && operands outside if condition mean then/else

Practically the statement says:

if (a=1 or b=2) then "ok" else "nok"

Obtaining UTC date

gmdate("Y-m-d H:i:s");

Obtaining UTC timestamp

time();

The result will not be different even you have date_default_timezone_set on your code.

There is a bug with Lee's extension code above, you need to add the newly filled row to the table t when iterating throught the items in the list.

public static DataSet ToDataSet<T>(this IList<T> list) {

Type elementType = typeof(T);
DataSet ds = new DataSet();
DataTable t = new DataTable();
ds.Tables.Add(t);

//add a column to table for each public property on T
foreach(var propInfo in elementType.GetProperties())
{
    t.Columns.Add(propInfo.Name, propInfo.PropertyType);
}

//go through each property on T and add each value to the table
foreach(T item in list)
{
    DataRow row = t.NewRow();
    foreach(var propInfo in elementType.GetProperties())
    {
            row[propInfo.Name] = propInfo.GetValue(item, null);
    }

    //This line was missing:
    t.Rows.Add(row);
}


return ds;

}

IEnumerable and IEnumerator both are interfaces in C#.

IEnumerable is an interface defining a single method GetEnumerator() that returns an IEnumerator interface.

This works for read-only access to a collection that implements that IEnumerable can be used with a foreach statement.

IEnumerator has two methods, MoveNext and Reset. It also has a property called Current.

The following shows the implementation of IEnumerable and IEnumerator.

If using Spring Boot this works well. Even with Spring Reactive Mongo.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

and validation config:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.core.mapping.event.ValidatingMongoEventListener;
import org.springframework.validation.beanvalidation.LocalValidatorFactoryBean;

@Configuration
public class MongoValidationConfig {

    @Bean
    public ValidatingMongoEventListener validatingMongoEventListener() {
        return new ValidatingMongoEventListener(validator());
    }

    @Bean
    public LocalValidatorFactoryBean validator() {
        return new LocalValidatorFactoryBean();
    }
}

It is general practice in various messaging protocols to keep heartbeating each other (keep sending ping packets) the packet does not need to be very large. The probing mechanism will allow you to detect the disconnected client even before TCP figures it out in general (TCP timeout is far higher) Send a probe and wait for say 5 seconds for a reply, if you do not see reply for say 2-3 subsequent probes, your player is disconnected.

If you don't want to make it final, you can always just make it a global variable.

You can write your php file to the action attr of form element.
At the php side you can get the form value by $_POST['element_name'].

Try this:

<script>
    window.onbeforeunload = function(e) {
       return 'Dialog text here.';
    };
</script>

more info here MDN.

You need to call format() function to get the formatted value

$scope.SearchDate = moment(new Date()).format("DD/MM/YYYY")
//or $scope.SearchDate = moment().format("DD/MM/YYYY")

The syntax you have used is used to parse a given string to date object by using the specified formate

The easiest way is this.

byte[] bytes = rs.getBytes("my_field");

var regex = /^[a-zA-Z0-9!@#\$%\^\&*\)\(+=._-]+$/g

Should work

Also may want to have a minimum length i.e. 6 characters

var regex = /^[a-zA-Z0-9!@#\$%\^\&*\)\(+=._-]{6,}$/g

If I get you right, you need ..\..\src

You may try something like this.

<div id="div1" >
    <input type="text" id="edit1" />
    <input type="text" id="edit2" />

function GetElementInsideContainer(containerID, childID) {
    var elm = {};
    var elms = document.getElementById(containerID).getElementsByTagName("*");
    for (var i = 0; i < elms.length; i++) {
        if (elms[i].id === childID) {
            elm = elms[i];
            break;
        }
    }
    return elm;
}

Demo: http://jsfiddle.net/naveen/H8j2A/

A better method as suggested by nnnnnn

function GetElementInsideContainer(containerID, childID) {
    var elm = document.getElementById(childID);
    var parent = elm ? elm.parentNode : {};
    return (parent.id && parent.id === containerID) ? elm : {};
}

Demo: http://jsfiddle.net/naveen/4JMgF/

Call it like

var e = GetElementInsideContainer("div1", "edit1");

In this jsfiddle you'll find a solution I deviced. The idea is to have a selector pair in html and use (plain) javascript to filter the options in the dependent selector, based on the selected option of the first. For example:

<select id="continents">
 <option value = 0>All</option>   
 <option value = 1>Asia</option>
 <option value = 2>Europe</option>
 <option value = 3>Africa</option>
</select> 
<select id="selectcountries"></select>

Uses (in the jsFiddle)

 MAIN.createRelatedSelector
     ( document.querySelector('#continents')           // from select element
      ,document.querySelector('#selectcountries')      // to select element
      ,{                                               // values object 
        Asia: ['China','Japan','North Korea',
               'South Korea','India','Malaysia',
               'Uzbekistan'],
        Europe: ['France','Belgium','Spain','Netherlands','Sweden','Germany'],
        Africa: ['Mali','Namibia','Botswana','Zimbabwe','Burkina Faso','Burundi']
      }
      ,function(a,b){return a>b ? 1 : a<b ? -1 : 0;}   // sort method
 );

[Edit 2021] or use data-attributes, something like:

document.addEventListener("change", checkSelect);

function checkSelect(evt) {
  const origin = evt.target;

  if (origin.dataset.dependentSelector) {
    const selectedOptFrom = origin.querySelector("option:checked")
      .dataset.dependentOpt || "n/a";
    const addRemove = optData => (optData || "") === selectedOptFrom 
      ? "add" : "remove";
    document.querySelectorAll(`${origin.dataset.dependentSelector} option`)
      .forEach( opt => 
        opt.classList[addRemove(opt.dataset.fromDependent)]("display") );
  }
}

[data-from-dependent] {
  display: none;
}

[data-from-dependent].display {
  display: initial;
}

<select id="source" name="source" data-dependent-selector="#status">
  <option>MANUAL</option>
  <option data-dependent-opt="ONLINE">ONLINE</option>
  <option data-dependent-opt="UNKNOWN">UNKNOWN</option>
</select>

<select id="status" name="status">
  <option>OPEN</option>
  <option>DELIVERED</option>
  <option data-from-dependent="ONLINE">SHIPPED</option>

Had a nightmare with this today Samsung Galaxy Note 9 and a Windows 10 Laptop without Android Studio. Here are working steps to get debugging.

1) Enable developer mode on the phone in the usual manner and turn on "USB Debugging".

2) On your computer install the Samsung USB Drivers for Windows https://developer.samsung.com/galaxy/others/android-usb-driver-for-windows

3) Open Chrome on your Computer - bring up Remote Devices in dev console (at the moment it will say no devices detected).

4) Connect your phone to your computer via USB cable.

5) Accept any prompts for authorisation and wait until the computer says "your device is ready.." etc.

6) On your phone, swipe down the top menu and tap "P Android system" - select "MIDI" under "Use USB for".

7) Various setup notifications will appear on your PC, when they are finished you will get the authorisation prompt for debugging on your phone. Accept it! Wait a few more second and you will find the phone now appears in Chrome Dev tools on the computer, and will be connected in a few more seconds.

You're welcome.

You want to initialize an array. (For more info - Tutorial)

int []ar={11,22,33};

String []stringAr={"One","Two","Three"};

From the JLS

The [] may appear as part of the type at the beginning of the declaration, or as part of the declarator for a particular variable, or both, as in this example:

byte[] rowvector, colvector, matrix[];

This declaration is equivalent to:

byte rowvector[], colvector[], matrix[][];

As sdleihssirhc says below, if the element's display is being inherited or being specified by a CSS rule, you'll need to get its computed style:

return window.getComputedStyle(element, null).display;

Elements have a style property that will tell you what you want, if the style was declared inline or with JavaScript:

console.log(document.getElementById('someIDThatExists').style.display);

will give you a string value.

Instead of using a bat file, you can simply create a Scheduled Task. Most of the time you define just one action. In this case, create two actions with the NET command. The first one to stop the service, the second one to start the service. Give them a STOP and START argument, followed by the service name.

In this example we restart the Printer Spooler service.

NET STOP "Print Spooler" 
NET START "Print Spooler"

Note: unfortunately NET RESTART <service name> does not exist.

I recently came across the same problem right after I installed Pandas 0.23 in Anaconda Prompt. The solution is simply to restart the Jupyter Notebook which reports the error. May it helps.

First connect the Height constraint in to our viewcontroller for creating IBOutlet like the below code shown

@IBOutlet weak var select_dateHeight: NSLayoutConstraint!

then put the below code in view did load or inside any actions

self.select_dateHeight.constant = 0 // we can change the height value

if it is inside a button click

@IBAction func Feedback_button(_ sender: Any) {
 self.select_dateHeight.constant = 0

}

An array is a variable, so in that case mapfile will work

mapfile y <<'z'
abc'asdf"
$(dont-execute-this)
foo"bar"''
z

Then you can print like this

printf %s "${y[@]}"

This happens to me when I'm using Jinja2 for templates. The problem can be solved by running the development server using the runserver_plus command from django_extensions.

It uses the werkzeug debugger which also happens to be a lot better and has a very nice interactive debugging console. It does some ajax magic to launch a python shell at any frame (in the call stack) so you can debug.

Right click on the project. Go to properties. Click on Run/Debug Settings. Now delete the run config of your main class that you are trying to run. Now, when you hit run again, things would work just fine.

If you want to center elements inside a div and don't care about division size you could use Flex power. I prefer using flex and don't use exact size for elements.

<div class="outer flex">
    <div class="inner">
        This is the inner Content
    </div>
</div>

As you can see Outer div is Flex container and Inner must be Flex item that specified with flex: 1 1 auto; for better understand you could see this simple sample. http://jsfiddle.net/QMaster/hC223/

Hope this help.

It would seem that _AMD64_ is not defined, since I can't imagine you are compiling for Itanium (_IA64_).

Tomalak already gave you a correct answer, but I would like to add that most of the times when you would like to know the VBA code needed to do a certain action in the user interface it is a good idea to record a macro.

In this case click Record Macro on the developer tab of the Ribbon, freeze the top row and then stop recording. Excel will have the following macro recorded for you which also does the job:

With ActiveWindow
    .SplitColumn = 0
    .SplitRow = 1
End With
ActiveWindow.FreezePanes = True

Aggregations and compositions are a little bit confusing. However, think like compositions are a stronger version of aggregation. What does that mean? Let's take an example: (Aggregation) 1. Take a classroom and students: In this case, we try to analyze the relationship between them. A classroom has a relationship with students. That means classroom comprises of one or many students. Even if we remove the Classroom class, the Students class does not need to destroy, which means we can use Student class independently.

(Composition) 2. Take a look at pages and Book Class. In this case, pages is a book, which means collections of pages makes the book. If we remove the book class, the whole Page class will be destroyed. That means we cannot use the class of the page independently.

If you are still unclear about this topic, watch out this short wonderful video, which has explained the aggregation more clearly.

First of all, shouldn't there be a CustomerId in the Invoices table? As it is, You can't perform this query for Invoices that have no payments on them as yet. If there are no payments on an invoice, that invoice will not even show up in the ouput of the query, even though it's an outer join...

Also, When a customer makes a payment, how do you know what Invoice to attach it to ? If the only way is by the InvoiceId on the stub that arrives with the payment, then you are (perhaps inappropriately) associating Invoices with the customer that paid them, rather than with the customer that ordered them... . (Sometimes an invoice can be paid by someone other than the customer who ordered the services)

I was having similar problem. It was just inserting one from the list of arrays. It worked after making the below changes.

1. Passed [params] to the query method.
2. Changed the query from insert (a,b) into table1 values (?) ==> insert (a,b) into table1 values ? . ie. Removed the paranthesis around the question mark.

Hope this helps. I am using mysql npm.

Let's say you have these lines of code:

test line one
test line two
test line three
test line four

Using Search and Replace Ctrl+H with Regex let's find this: ^ and replace it with ", we'll have this:

"test line one
"test line two
"test line three
"test line four

Now let's search this: $ and replace it with ", now we'll have this:

"test line one"
"test line two"
"test line three"
"test line four"

Under TARGETS in your project, right-click on your project target (should be the same name as your project) and choose GET INFO, then on GENERAL tab you will see DIRECT DEPENDENCIES, simply click the [+] and select SoundCloudAPI.

One more point to add.Along with above upvoted answers, please make sure the below line is added to app.py file:

app = Flask(__name__, static_folder="your path to static")

Otherwise flask will not be able to detect static folder.

Tuples aren't supported in JavaScript

If you're looking for an immutable list, Object.freeze() can be used to make an array immutable.

The Object.freeze() method freezes an object: that is, prevents new properties from being added to it; prevents existing properties from being removed; and prevents existing properties, or their enumerability, configurability, or writability, from being changed. In essence the object is made effectively immutable. The method returns the object being frozen.

Source: Mozilla Developer Network - Object.freeze()

Assign an array as usual but lock it using 'Object.freeze()

> tuple = Object.freeze(['Bob', 24]);
[ 'Bob', 24 ]

Use the values as you would a regular array (python multi-assignment is not supported)

> name = tuple[0]
'Bob'
> age = tuple[1]
24

Attempt to assign a new value

> tuple[0] = 'Steve'
'Steve'

But the value is not changed

> console.log(tuple)
[ 'Bob', 24 ]

It's a setting in chrome. You can't control how the browser interprets the target _blank.

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

To much code, you can use it like this:

#include<array>
#include<functional>

int main()
{
    std::array<int, 10> vec = { 1,2,3,4,5,6,7,8,9 };

    std::sort(std::begin(vec), 
              std::end(vec), 
              [](int a, int b) {return a > b; });

    for (auto item : vec)
      std::cout << item << " ";

    return 0;
}

Replace "vec" with your class and that's it.

The spirit of Web font is to use cache as much as possible, therefore you should use CDN version between <head></head> instead of hosting yourself:

<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css" rel="stylesheet">

Also, make sure you loaded your CSS AFTER the above line, or your custom font CSS won't work.

From the Solution Explorer window select your form, right-click, click on View Designer. Voila! The form should display.

I tried posting a couple screenshots, but this is my first post; therefore, I could not post any images.

Another option is to enclose the unwanted lines in an IF block that can never be true

if 1==0 (
...
)

Of course nothing within the if block will be executed, but it will be parsed. So you can't have any invalid syntax within. Also, the comment cannot contain ) unless it is escaped or quoted. For those reasons the accepted GOTO solution is more reliable. (The GOTO solution may also be faster)

Update 2017-09-19

Here is a cosmetic enhancement to pdub's GOTO solution. I define a simple environment variable "macro" that makes the GOTO comment syntax a bit better self documenting. Although it is generally recommended that :labels are unique within a batch script, it really is OK to embed multiple comments like this within the same batch script.

@echo off
setlocal

set "beginComment=goto :endComment"

%beginComment%
Multi-line comment 1
goes here
:endComment

echo This code executes

%beginComment%
Multi-line comment 2
goes here
:endComment

echo Done

Or you could use one of these variants of npocmaka's solution. The use of REM instead of BREAK makes the intent a bit clearer.

rem.||(
   remarks
   go here
)

rem^ ||(
   The space after the caret
   is critical
)

Git has three modes of how it treats line endings:

$ git config core.autocrlf
# that command will print "true" or "false" or "input"

You can set the mode to use by adding an additional parameter of true or false to the above command line.

If core.autocrlf is set to true, that means that any time you add a file to the git repo that git thinks is a text file, it will turn all CRLF line endings to just LF before it stores it in the commit. Whenever you git checkout something, all text files automatically will have their LF line endings converted to CRLF endings. This allows development of a project across platforms that use different line-ending styles without commits being very noisy because each editor changes the line ending style as the line ending style is always consistently LF.

The side-effect of this convenient conversion, and this is what the warning you're seeing is about, is that if a text file you authored originally had LF endings instead of CRLF, it will be stored with LF as usual, but when checked out later it will have CRLF endings. For normal text files this is usually just fine. The warning is a "for your information" in this case, but in case git incorrectly assesses a binary file to be a text file, it is an important warning because git would then be corrupting your binary file.

If core.autocrlf is set to false, no line-ending conversion is ever performed, so text files are checked in as-is. This usually works ok, as long as all your developers are either on Linux or all on Windows. But in my experience I still tend to get text files with mixed line endings that end up causing problems.

My personal preference is to leave the setting turned ON, as a Windows developer.

See http://kernel.org/pub/software/scm/git/docs/git-config.html for updated info that includes the "input" value.

There's nothing here explaining the use of multiple variables, so I'll chuck it in just incase someone needs it in the future.

You need to concatenate multiple variables:

header('Location: http://linkhere.com?var1='.$var1.'&var2='.$var2.'&var3'.$var3);

I really recommend you read about Information Theory, bayesian methods and MaxEnt. The place to start is this (freely available online) book by David Mackay:

http://www.inference.phy.cam.ac.uk/mackay/itila/

Those inference methods are really far more general than just text mining and I can't really devise how one would learn how to apply this to NLP without learning some of the general basics contained in this book or other introductory books on Machine Learning and MaxEnt bayesian methods.

The connection between entropy and probability theory to information processing and storing is really, really deep. To give a taste of it, there's a theorem due to Shannon that states that the maximum amount of information you can pass without error through a noisy communication channel is equal to the entropy of the noise process. There's also a theorem that connects how much you can compress a piece of data to occupy the minimum possible memory in your computer to the entropy of the process that generated the data.

I don't think it's really necessary that you go learning about all those theorems on communication theory, but it's not possible to learn this without learning the basics about what is entropy, how it's calculated, what is it's relationship with information and inference, etc...

This question is already answered here

The classpath never includes specific files. It includes directories and jar files. So, put that file in a directory that is in your classpath.

Log4j properties aren't (normally) used in developing apps (unless you're debugging Eclipse itself!). So what you really want to to build the executable Java app (Application, WAR, EAR or whatever) and include the Log4j properties in the runtime classpath.

Another option, using the command module:

- name: Create file
  command: touch /path/to/file
  args:
    creates: /path/to/file

The 'creates' argument ensures that this action is not performed if the file exists.

If you are considering using multidimensional arrays, then there is one additional difference between std::array and std::vector. A multidimensional std::array will have the elements packed in memory in all dimensions, just as a c style array is. A multidimensional std::vector will not be packed in all dimensions.

Given the following declarations:

int cConc[3][5];
std::array<std::array<int, 5>, 3> aConc;
int **ptrConc;      // initialized to [3][5] via new and destructed via delete
std::vector<std::vector<int>> vConc;    // initialized to [3][5]

A pointer to the first element in the c-style array (cConc) or the std::array (aConc) can be iterated through the entire array by adding 1 to each preceding element. They are tightly packed.

A pointer to the first element in the vector array (vConc) or the pointer array (ptrConc) can only be iterated through the first 5 (in this case) elements, and then there are 12 bytes (on my system) of overhead for the next vector.

This means that a std::vector> array initialized as a [3][1000] array will be much smaller in memory than one initialized as a [1000][3] array, and both will be larger in memory than a std:array allocated either way.

This also means that you can't simply pass a multidimensional vector (or pointer) array to, say, openGL without accounting for the memory overhead, but you can naively pass a multidimensional std::array to openGL and have it work out.

This happened for me when I was trying to stash my changes, but then my changes had conflicts with my branch's current state.

So I did git reset --mixed and then resolved the git conflict and stashed again.

You can also use the NSString class methods which will also create an autoreleased instance and have more options like string formatting:

NSString *myString = [NSString stringWithString:@"abc"];
NSString *myString = [NSString stringWithFormat:@"abc %d efg", 42];

\r is a carriage return character; it tells your terminal emulator to move the cursor at the start of the line.

The cursor is the position where the next characters will be rendered.

So, printing a \r allows to override the current line of the terminal emulator.

Tom Zych figured why the output of your program is o world while the \r is at the end of the line and you don't print anything after that:

When your program exits, the shell prints the command prompt. The terminal renders it where you left the cursor. Your program leaves the cursor at the start of the line, so the command prompt partly overrides the line you printed. This explains why you seen your command prompt followed by o world.

The online compiler you mention just prints the raw output to the browser. The browser ignores control characters, so the \r has no effect.

See https://en.wikipedia.org/wiki/Carriage_return

Here is a usage example of \r:

#include <stdio.h>
#include <unistd.h>

int main()
{
        char chars[] = {'-', '\\', '|', '/'};
        unsigned int i;

        for (i = 0; ; ++i) {
                printf("%c\r", chars[i % sizeof(chars)]);
                fflush(stdout);
                usleep(200000);
        }

        return 0;
}

It repeatedly prints the characters - \ | / at the same position to give the illusion of a rotating | in the terminal.

You can do it with PHP:

header("Refresh:0");

It refreshes your current page, and if you need to redirect it to another page, use following:

header("Refresh:0; url=page2.php");

In Windows, like this:

-Djava.library.path="C:/MyLibPath;%PATH%"

%PATH% is your old -Djava.library.path

Edit your AndroidManifest.xml to add RECEIVE_BOOT_COMPLETED permission

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

Edit your AndroidManifest.xml application-part for below Permission

<receiver android:enabled="true" android:name=".BootUpReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

Now write below in Activity.

public class BootUpReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent i = new Intent(context, MyActivity.class);  
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);  
    }
}

Make a state machine that operates on one basic principle: is the current character a number.

• When transitioning from non-digit to digit, you initialize your current_number := number.
• when transitioning from digit to digit, you "shift" the new digit in:
  current_number := current_number * 10 + number;
• when transitioning from digit to non-digit, you output the current_number
• when from non-digit to non-digit, you do nothing.

Optimizations are possible.

It's subtle.

If the business requirement is "I want to audit the changes to the data - who did what and when?", you can usually use audit tables (as per the trigger example Keethanjan posted). I'm not a huge fan of triggers, but it has the great benefit of being relatively painless to implement - your existing code doesn't need to know about the triggers and audit stuff.

If the business requirement is "show me what the state of the data was on a given date in the past", it means that the aspect of change over time has entered your solution. Whilst you can, just about, reconstruct the state of the database just by looking at audit tables, it's hard and error prone, and for any complicated database logic, it becomes unwieldy. For instance, if the business wants to know "find the addresses of the letters we should have sent to customers who had outstanding, unpaid invoices on the first day of the month", you likely have to trawl half a dozen audit tables.

Instead, you can bake the concept of change over time into your schema design (this is the second option Keethanjan suggests). This is a change to your application, definitely at the business logic and persistence level, so it's not trivial.

For example, if you have a table like this:

CUSTOMER
---------
CUSTOMER_ID PK
CUSTOMER_NAME
CUSTOMER_ADDRESS

and you wanted to keep track over time, you would amend it as follows:

CUSTOMER
------------
CUSTOMER_ID            PK
CUSTOMER_VALID_FROM    PK
CUSTOMER_VALID_UNTIL   PK
CUSTOMER_STATUS
CUSTOMER_USER
CUSTOMER_NAME
CUSTOMER_ADDRESS

Every time you want to change a customer record, instead of updating the record, you set the VALID_UNTIL on the current record to NOW(), and insert a new record with a VALID_FROM (now) and a null VALID_UNTIL. You set the "CUSTOMER_USER" status to the login ID of the current user (if you need to keep that). If the customer needs to be deleted, you use the CUSTOMER_STATUS flag to indicate this - you may never delete records from this table.

That way, you can always find what the status of the customer table was for a given date - what was the address? Have they changed name? By joining to other tables with similar valid_from and valid_until dates, you can reconstruct the entire picture historically. To find the current status, you search for records with a null VALID_UNTIL date.

It's unwieldy (strictly speaking, you don't need the valid_from, but it makes the queries a little easier). It complicates your design and your database access. But it makes reconstructing the world a lot easier.

This can be done using Actions class in java

Use following code -

new Actions(driver).moveByOffset(x coordinate, y coordinate).click().build().perform(); 

Note: Selenium 3 doesn't support Actions class for geckodriver

Also, note that x and y co-ordinates are relative values from current mouse position. Assuming mouse co-ordinates are at (0,0) to start with, if you want to use absolute values, you can perform the below action immediately after you clicked on it using the above code.

new Actions(driver).moveByOffset(-x coordinate, -y coordinate).perform();

For simple solutions you can just Overwrite the "toString" in your object

public class User{
    public int ID;
    public String name;

    @Override
    public String toString() {
        return name;
    }
}

and then you can use:

ArrayAdapter<User> dataAdapter = new ArrayAdapter<User>(mContext, android.R.layout.simple_spinner_item, listOfUsers);

This way your spinner will show only the user names.

I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.

Java Heap Memory is part of memory allocated to JVM by Operating System.

Objects reside in an area called the heap. The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected.

You can find more details about Eden Space, Survivor Space, Tenured Space and Permanent Generation in below SE question:

Young , Tenured and Perm generation

PermGen has been replaced with Metaspace since Java 8 release.

Regarding your queries:

1. Eden Space, Survivor Space, Tenured Space are part of heap memory
2. Metaspace and Code Cache are part of non-heap memory.

Codecache: The Java Virtual Machine (JVM) generates native code and stores it in a memory area called the codecache. The JVM generates native code for a variety of reasons, including for the dynamically generated interpreter loop, Java Native Interface (JNI) stubs, and for Java methods that are compiled into native code by the just-in-time (JIT) compiler. The JIT is by far the biggest user of the codecache.

in the manifest:

<activity android:name=".activity.MainActivity"
        android:screenOrientation="portrait"
        tools:ignore="LockedOrientationActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

or : in the MainActivity

@SuppressLint("SourceLockedOrientationActivity")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

I built a RSS feed app in which I have a Pull To refresh feature that originally had some of the problems listed above.

But to add to the users answers above, I was looking everywhere for my use case and could not find it. I was downloading data from the web (RSSFeed) and I wanted to pull down on my tableView of stories to refresh.

What is mentioned above cover the right areas but with some of the problems people are having, here is what I did and it works a treat:

I took @Blankarsch 's approach and went to my main.storyboard and select the table view to use refresh, then what wasn't mentioned is creating IBOutlet and IBAction to use the refresh efficiently

//Created from main.storyboard cntrl+drag refresh from left scene to assistant editor_x000D_
@IBOutlet weak var refreshButton: UIRefreshControl_x000D_
_x000D_

  //Include your code_x000D_
  ......_x000D_

  //Is the function called below, make sure to put this in your viewDidLoad _x000D_

func getFeedData() -> Void{_x000D_
  ....._x000D_

}_x000D_
_x000D_
//From main.storyboard cntrl+drag to assistant editor and this time create an action instead of outlet and _x000D_

_x000D_
  //note: refreshControl doesnt need to be declared it is already initailized. Got to love xcode_x000D_

}

Hope this helps anyone in same situation as me

Safe navigation operator or Existential Operator or Null Propagation Operator is supported in Angular Template. Suppose you have Component class

  myObj:any = {
    doSomething: function () { console.log('doing something'); return 'doing something'; },
  };
  myArray:any;
  constructor() { }

  ngOnInit() {
    this.myArray = [this.myObj];
  }

You can use it in template html file as following:

<div>test-1: {{  myObj?.doSomething()}}</div>
<div>test-2: {{  myArray[0].doSomething()}}</div>
<div>test-3: {{  myArray[2]?.doSomething()}}</div>

Adding to joquin's answer the following form might be a bit cleaner (at least nicer to read):

x = p.Series()
N = 4
for i in xrange(N):
   x[i] = i**2

which would produce the same output

also, a bit less orthodox but if you wanted to simply add a single element to the end:

x=p.Series()
value_to_append=5
x[len(x)]=value_to_append

Something like:

clients.stream.filter(c->{
   users.stream.filter(u->u.getName().equals(c.getName()).count()>0
}).collect(Collectors.toList());

This is however not an awfully efficient way to do it. Unless the collections are very small, you will be better of building a set of user names and using that in the condition.

You can effectively remove scientific notation in printing with this code:

options(scipen=999)

As Sagiv b.g. pointed out, the npm start command is a shortcut for npm run start. I just wanted to add a real-life example to clarify it a bit more.

The setup below comes from the create-react-app github repo. The package.json defines a bunch of scripts which define the actual flow.

"scripts": {
  "start": "npm-run-all -p watch-css start-js",
  "build": "npm run build-css && react-scripts build",
  "watch-css": "npm run build-css && node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/ --watch --recursive",
  "build-css": "node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/",
  "start-js": "react-scripts start"
},

For clarity, I added a diagram.

The blue boxes are references to scripts, all of which you could executed directly with an npm run <script-name> command. But as you can see, actually there are only 2 practical flows:

• npm run start
• npm run build

The grey boxes are commands which can be executed from the command line.

So, for instance, if you run npm start (or npm run start) that actually translate to the npm-run-all -p watch-css start-js command, which is executed from the commandline.

In my case, I have this special npm-run-all command, which is a popular plugin that searches for scripts that start with "build:", and executes all of those. I actually don't have any that match that pattern. But it can also be used to run multiple commands in parallel, which it does here, using the -p <command1> <command2> switch. So, here it executes 2 scripts, i.e. watch-css and start-js. (Those last mentioned scripts are watchers which monitor file changes, and will only finish when killed.)

• The watch-css makes sure that the *.scss files are translated to *.cssfiles, and looks for future updates.

• The start-js points to the react-scripts start which hosts the website in a development mode.

In conclusion, the npm start command is configurable. If you want to know what it does, then you have to check the package.json file. (and you may want to make a little diagram when things get complicated).

My 2 cents: Compile against any version of the SDK but take care not to call any APIs that your "minimum SDK version" does not support. That means you "could" compile against the latest version of the SDK.

As for "target version" it simply refers to what you planned to target in the first place and have possibly tested against. If you haven't done the due diligence then this is the way to inform Android that it needs to perform some additional checks before it deploys your lets say "Lollipop" targeted app on "Oreo".

So the "target version" is obviously not lower than your "minimum SDK version" but it can't be higher than your "compiled version".

SIGABRT is, as stated in other answers, a general uncaught exception. You should definitely learn a little bit more about Objective-C. The problem is probably in your UITableViewDelegate method didSelectRowAtIndexPath.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

I can't tell you much more until you show us something of the code where you handle the table data source and delegate methods.

What about initializing a variable at the top of the class with a default value? For example:

public class SomeClass {
    private int maxRows = 15000;
    ...
    // Inside another method
    for (int i = 0; i < maxRows; i++) {
        // Do something
    }

    public void setMaxRows(int maxRows) {
        this.maxRows = maxRows;
    }

    public int getMaxRows() {
        return this.maxRows;
    }

In this case, 15000 is a magic number (according to CheckStyles). To me, setting a default value is okay. I don't want to have to do:

private static final int DEFAULT_MAX_ROWS = 15000;
private int maxRows = DEFAULT_MAX_ROWS;

Does that make it more difficult to read? I never considered this until I installed CheckStyles.

If new does the job for you, then it will make your code modestly smaller as well. If you would otherwise call [[SomeClass alloc] init] in many different places in your code, you will create a Hot Spot in new's implementation - that is, in the objc runtime - that will reduce the number of your cache misses.

In my understanding, if you need to use a custom initializer use [[SomeClass alloc] initCustom].

If you don't, use [SomeClass new].

I had the same problem in the iphone or desktop, didnt manage to close the dialog when pressing the close button.

i found out that The <button> tag defines a clickable button and is needed to specify the type attribute for a element as follow:

<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>

I was having issues getting this working (on OSX). I'd followed the instructions provided by Postman, and the advice here, and cookies were still not being set.

However, the post above saying "So if you enable interceptor only in browser - it will not work" alerted me to the fact that the interceptor could be enabled in the browser as well as in Postman itself. I thought I'd try switching it on in the browser, to see if that helped, and it did. I then switched it off in the browser, and it still worked.

So, if you are having issues getting it working, I'd suggest trying switching it on in browser at least once, as, for me, this seemed to trigger it into life. I think you will still need it switch on in Postman too.

You can solve this problem using this code:

if(!empty($_GET['variable from which you get'])) 
{
$_SESSION['something']= $_GET['variable from which you get'];
}

So you get the variable from a GET form, you will store in the $_SESSION['whatever'] variable just once when $_GET['variable from which you get']is set and if it is empty $_SESSION['something'] will store the old parameter

In my case I was using a custom extension for my PHP files and I had to edit /etc/apache2/conf-available/php7.2-fpm.conf and add the following code:

    <FilesMatch ".+\.YOUR_CUSTOM_EXTENSION$">
        SetHandler "proxy:unix:/run/php/php7.2-fpm.sock|fcgi://localhost"
    </FilesMatch>

If you need to use multiple dialog boxes on one page and open, close and reopen them the following works well:

 JS CODE:
    $(".sectionHelp").click(function(){
        $("#dialog_"+$(this).attr('id')).dialog({autoOpen: false});
        $("#dialog_"+$(this).attr('id')).dialog("open");
    });

 HTML: 
    <div class="dialog" id="dialog_help1" title="Dialog Title 1">
        <p>Dialog 1</p>
    </div>
    <div class="dialog" id="dialog_help2" title="Dialog Title 2">
        <p>Dialog 2 </p>
    </div>

    <a href="#" id="help1" class="sectionHelp"></a>
    <a href="#" id="help2" class="sectionHelp"></a>

 CSS:
    div.dialog{
      display:none;
    }

I have found the designer "update from database" can only handle small changes. If you have deleted tables, changed foreign keys or (gasp) changed the signature of a stored procedure with a function mapping, you will eventually get to such a messed up state you will have to either delete all the entities and "add from database" or simply delete the edmx resource and start over.

Use mysql-connector-python. I prefer to install it with pip from PyPI:

pip install --allow-external mysql-connector-python mysql-connector-python

Have a look at its documentation and examples.

If you are going to use pooling make sure your database has enough connections available as the default settings may not be enough.

During migration from Ubuntu 12.04 to 14.04 I stumbled over this as well and wanted to share that as of Ubuntu 14.04 LTS the IMAP extension seems no longer to be loaded per default.

Check to verify if the extension is installed:

dpkg -l | grep php5-imap

should give a response like this:

ii  php5-imap       5.4.6-0ubuntu5   amd64        IMAP module for php5

if not, install it.

To actually enable the extension

cd /etc/php5/apache2/conf.d
ln -s ../../mods-available/imap.ini 20-imap.ini
service apache2 restart

should fix it for apache. For CLI do the same in /etc/php5/cli/conf.d

a.h:

#ifndef A_H
#define A_H

struct a { 
    int i;
    struct b {
        int j;
    }
};

#endif

there you go, now you just need to include a.h to the files where you want to use this structure.

The # tag lets you send your data to the same file. I see it as a three step process:

1. Query a DB to populate a from
2. Allow the user to change data in the form
3. Resubmit the data to the DB via the php script

With the method='#' you can do all of this in the same file.

After the submit query is executed the page will reload with the updated data from the DB.

Use dynamic_cast for converting pointers/references within an inheritance hierarchy.

Use static_cast for ordinary type conversions.

Use reinterpret_cast for low-level reinterpreting of bit patterns. Use with extreme caution.

Use const_cast for casting away const/volatile. Avoid this unless you are stuck using a const-incorrect API.

Use NSError to communicate failures rather than exceptions.

Quick points about NSError:

• NSError allows for C style error codes (integers) to clearly identify the root cause and hopefully allow the error handler to overcome the error. You can wrap error codes from C libraries like SQLite in NSError instances very easily.

• NSError also has the benefit of being an object and offers a way to describe the error in more detail with its userInfo dictionary member.

• But best of all, NSError CANNOT be thrown so it encourages a more proactive approach to error handling, in contrast to other languages which simply throw the hot potato further and further up the call stack at which point it can only be reported to the user and not handled in any meaningful way (not if you believe in following OOP's biggest tenet of information hiding that is).

Reference Link: Reference

You can simply use this: \This is .*? \sentence

If you have cygwin installed, from it's bash shell, run your executable, say MyProgram, using the time utility, like so:

/usr/bin/time ./MyProgram

This will report how long the execution of your program took -- the output would look something like the following:

real    0m0.792s
user    0m0.046s
sys     0m0.218s

You could also manually modify your C program to instrument it using the clock() library function, like so:

#include <time.h>
int main(void) {
    clock_t tStart = clock();
    /* Do your stuff here */
    printf("Time taken: %.2fs\n", (double)(clock() - tStart)/CLOCKS_PER_SEC);
    return 0;
}

If there is no randomstate provided the system will use a randomstate that is generated internally. So, when you run the program multiple times you might see different train/test data points and the behavior will be unpredictable. In case, you have an issue with your model you will not be able to recreate it as you do not know the random number that was generated when you ran the program.

If you see the Tree Classifiers - either DT or RF, they try to build a try using an optimal plan. Though most of the times this plan might be the same there could be instances where the tree might be different and so the predictions. When you try to debug your model you may not be able to recreate the same instance for which a Tree was built. So, to avoid all this hassle we use a random_state while building a DecisionTreeClassifier or RandomForestClassifier.

PS: You can go a bit in depth on how the Tree is built in DecisionTree to understand this better.

randomstate is basically used for reproducing your problem the same every time it is run. If you do not use a randomstate in traintestsplit, every time you make the split you might get a different set of train and test data points and will not help you in debugging in case you get an issue.

From Doc:

If int, randomstate is the seed used by the random number generator; If RandomState instance, randomstate is the random number generator; If None, the random number generator is the RandomState instance used by np.random.

The most straight forward answer to this question is: You can't.

Youtube doesn't output their video's in the right format, thus they can't be embedded in a
<video/> element.

There are a few solutions posted using javascript, but don't trust on those, they all need a fallback, and won't work cross-browser.

try a right click on the variable and select inspect, then it should come up in a popup window

There is no version 1.3.0 for rope. 1.3.0 refers to the package cached-property. The highest available version of rope is 0.9.4.

You can install different versions with conda install package=version. But in this case there is only one version of rope so you don't need that.

The reason you see the cached-property in this listing is because it contains the string "rope": "cached-p rope erty"

py35_0 means that you need python version 3.5 for this specific version. If you only have python3.4 and the package is only for version 3.5 you cannot install it with conda.

I am not quite sure on the defaults either. It should be an indication that this package is inside the default conda channel.

Imagine it this way

*main() is also a function which is called by something else (like another FunctioN)

*the arguments to it is decided by the FunctioN

*the second argument is an array of strings

*the first argument is a number representing the number of strings

*do something with the strings

Maybe a example program woluld help.

int main(int argc,char *argv[])
{

    printf("you entered in reverse order:\n");

    while(argc--)
    {
        printf("%s\n",argv[argc]);
    }

return 0;
}

it just prints everything you enter as args in reverse order but YOU should make new programs that do something more useful.

compile it (as say hello) run it from the terminal with the arguments like

./hello am i here

then try to modify it so that it tries to check if two strings are reverses of each other or not then you will need to check if argc parameter is exactly three if anything else print an error

if(argc!=3)/*3 because even the executables name string is on argc*/
{
    printf("unexpected number of arguments\n");
    return -1;
}

then check if argv[2] is the reverse of argv[1] and print the result

./hello asdf fdsa

should output

they are exact reverses of each other

the best example is a file copy program try it it's like cp

cp file1 file2

cp is the first argument (argv[0] not argv[1]) and mostly you should ignore the first argument unless you need to reference or something

if you made the cp program you understood the main args really...

The correct answer is, that, because the '%'-sign is part of your search expression, it should be part of your VALUE, so whereever you SET @LastName (be it from a programming language or from TSQL) you should set it to '%' + [userinput] + '%'

or, in your example:

DECLARE @LastName varchar(max)
SET @LastName = 'ning'
SELECT Employee WHERE LastName LIKE '%' + @LastName + '%'

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

You can follow this answer to see many different ways to process CSV in C++.

In your case, the last call to getline is actually putting the last field of the first line and then all of the remaining lines into the variable genero. This is because there is no space delimiter found up until the end of file. Try changing the space character into a newline instead:

    getline(file, genero, file.widen('\n'));

or more succinctly:

    getline(file, genero);

In addition, your check for file.good() is premature. The last newline in the file is still in the input stream until it gets discarded by the next getline() call for ID. It is at this point that the end of file is detected, so the check should be based on that. You can fix this by changing your while test to be based on the getline() call for ID itself (assuming each line is well formed).

while (getline(file, ID, ',')) {
    cout << "ID: " << ID << " " ; 

    getline(file, nome, ',') ;
    cout << "User: " << nome << " " ;

    getline(file, idade, ',') ;
    cout << "Idade: " << idade << " "  ; 

    getline(file, genero);
    cout << "Sexo: " <<  genero<< " "  ;
}

For better error checking, you should check the result of each call to getline().

Assuming your code is inside an MVC controller:

public class MyController : Microsoft.AspNetCore.Mvc.Controller

From the Controller base class, you can get the IClaimsPrincipal from the User property

System.Security.Claims.ClaimsPrincipal currentUser = this.User;

You can check the claims directly (without a round trip to the database):

bool IsAdmin = currentUser.IsInRole("Admin");
var id = _userManager.GetUserId(User); // Get user id:

Other fields can be fetched from the database's User entity:

1. Get the user manager using dependency injection

   private UserManager<ApplicationUser> _userManager;
   
   //class constructor
   public MyController(UserManager<ApplicationUser> userManager)
   {
       _userManager = userManager;
   }
   

2. And use it:

   var user = await _userManager.GetUserAsync(User);
   var email = user.Email;
   

Monads in typical usage are the functional equivalent of procedural programming's exception handling mechanisms.

In modern procedural languages, you put an exception handler around a sequence of statements, any of which may throw an exception. If any of the statements throws an exception, normal execution of the sequence of statements halts and transfers to an exception handler.

Functional programming languages, however, philosophically avoid exception handling features due to the "goto" like nature of them. The functional programming perspective is that functions should not have "side-effects" like exceptions that disrupt program flow.

In reality, side-effects cannot be ruled out in the real world due primarily to I/O. Monads in functional programming are used to handle this by taking a set of chained function calls (any of which might produce an unexpected result) and turning any unexpected result into encapsulated data that can still flow safely through the remaining function calls.

The flow of control is preserved but the unexpected event is safely encapsulated and handled.

If you revise your regular expression like this:

drupal-6.14/(?=sites(?!/all|/default)).*
             ^^

...then it will match all inputs that contain drupal-6.14/ followed by sites followed by anything other than /all or /default. For example:

drupal-6.14/sites/foo
drupal-6.14/sites/bar
drupal-6.14/sitesfoo42
drupal-6.14/sitesall

Changing ?= to ?! to match your original regex simply negates those matches:

drupal-6.14/(?!sites(?!/all|/default)).*
             ^^

So, this simply means that drupal-6.14/ now cannot be followed by sites followed by anything other than /all or /default. So now, these inputs will satisfy the regex:

drupal-6.14/sites/all
drupal-6.14/sites/default
drupal-6.14/sites/all42

But, what may not be obvious from some of the other answers (and possibly your question) is that your regex will also permit other inputs where drupal-6.14/ is followed by anything other than sites as well. For example:

drupal-6.14/foo
drupal-6.14/xsites

Conclusion: So, your regex basically says to include all subdirectories of drupal-6.14 except those subdirectories of sites whose name begins with anything other than all or default.

With a help of a small convenience class, you can measure time spent in indented lines like this:

with CodeTimer():
   line_to_measure()
   another_line()
   # etc...

Which will show the following after the indented line(s) finishes executing:

Code block took: x.xxx ms

UPDATE: You can now get the class with pip install linetimer and then from linetimer import CodeTimer. See this GitHub project.

The code for above class:

import timeit

class CodeTimer:
    def __init__(self, name=None):
        self.name = " '"  + name + "'" if name else ''

    def __enter__(self):
        self.start = timeit.default_timer()

    def __exit__(self, exc_type, exc_value, traceback):
        self.took = (timeit.default_timer() - self.start) * 1000.0
        print('Code block' + self.name + ' took: ' + str(self.took) + ' ms')

You could then name the code blocks you want to measure:

with CodeTimer('loop 1'):
   for i in range(100000):
      pass

with CodeTimer('loop 2'):
   for i in range(100000):
      pass

Code block 'loop 1' took: 4.991 ms
Code block 'loop 2' took: 3.666 ms

And nest them:

with CodeTimer('Outer'):
   for i in range(100000):
      pass

   with CodeTimer('Inner'):
      for i in range(100000):
         pass

   for i in range(100000):
      pass

Code block 'Inner' took: 2.382 ms
Code block 'Outer' took: 10.466 ms

Regarding timeit.default_timer(), it uses the best timer based on OS and Python version, see this answer.

Example-

For cells containing the values between 21-31, the formula is:

=COUNTIF(M$7:M$83,">21")-COUNTIF(M$7:M$83,">31")

mysql servers are usually configured to listen only to localhost (127.0.0.1), where they are used by web applications.

If that is your case but you have SSH access to your server, you can create an ssh tunnel and connect through that.

On your local machine, create the tunnel.

ssh -L 3307:127.0.0.1:3306 -N $user@$remote_host

(this example uses local port 3307, in case you also have mysql running on your local machine and using the standard port 3306)

Now you should be ale to connect with

mysql -u $user -p -h 127.0.0.1 -P 3307

only css, quite simple I find it:

.checkmark {_x000D_
      display: inline-block;_x000D_
      transform: rotate(45deg);_x000D_
      height: 25px;_x000D_
      width: 12px;_x000D_
      margin-left: 60%; _x000D_
      border-bottom: 7px solid #78b13f;_x000D_
      border-right: 7px solid #78b13f;_x000D_
    }

<div class="checkmark"></div>

In C, 'extern' is implied for function prototypes, as a prototype declares a function which is defined somewhere else. In other words, a function prototype has external linkage by default; using 'extern' is fine, but is redundant.

(If static linkage is required, the function must be declared as 'static' both in its prototype and function header, and these should normally both be in the same .c file).

I think you could do it by creating parameters in an object maybe?

var myObject = {}; for(var i=0;i<myArray.length;i++) {     myObject[ myArray[i] ]; } 

If you don't set them to anything, you'll just have an object with some parameters that are undefined. I'd have to write this myself to be sure though.

Here is a somehow portable hack for Linux for getting time in milliseconds:

#!/bin/sh
read up rest </proc/uptime; t1="${up%.*}${up#*.}"
sleep 3    # your command
read up rest </proc/uptime; t2="${up%.*}${up#*.}"

millisec=$(( 10*(t2-t1) ))
echo $millisec

The output is:

3010

This is a very cheap operation, which works with shell internals and procfs.

"Not equals" can be expressed with the "not" operator ! and the standard .equals.

if (a.equals(b)) // a equals b
if (!a.equals(b)) // a not equal to b

When you're working with strings in PHP you'll need to pay special attention to the formation, using " or '

$string = 'Hello, world!';
$string = "Hello, world!";

Both of these are valid, the following is not:

$string = "Hello, world';

You must also note that ' inside of a literal started with " will not end the string, and vice versa. So when you have a string which contains ', it is generally best practice to use double quotation marks.

$string = "It's ok here";

Escaping the string is also an option

$string = 'It\'s ok here too';

More information on this can be found within the documentation

You are not initializing your String[]. You either need to initialize it using the exact array size, as suggested by @Tr?nSiLong, or use a List<String> and then convert to a String[] (in case you do not know the length):

String[] title = {
        "Abundance",
        "Anxiety",
        "Bruxism",
        "Discipline",
        "Drug Addiction"
    };
String urlbase = "http://www.somewhere.com/data/";
String imgSel = "/logo.png";
List<String> mStrings = new ArrayList<String>();

for(int i=0;i<title.length;i++) {
    mStrings.add(urlbase + title[i].toLowerCase() + imgSel);

    System.out.println(mStrings[i]);
}

String[] strings = new String[mStrings.size()];
strings = mStrings.toArray(strings);//now strings is the resulting array

Just using max-width: 0 in the display: table-cell element worked for me:

  width: 100%;_x000D_
}_x000D_
_x000D_
.table-cell {_x000D_

<form id="my-form">
    <input type="text" name="in" value="some data" />
    <button type="submit">Go</button>
</form>

In JS:

function processForm(e) {
    if (e.preventDefault) e.preventDefault();

    /* do what you want with the form */

    // You must return false to prevent the default form behavior
    return false;
}

var form = document.getElementById('my-form');
if (form.attachEvent) {
    form.attachEvent("submit", processForm);
} else {
    form.addEventListener("submit", processForm);
}

Edit: in my opinion, this approach is better than setting the onSubmit attribute on the form since it maintains separation of mark-up and functionality. But that's just my two cents.

Edit2: Updated my example to include preventDefault()
