This is the modern way of reloading a module:

from importlib import reload

If you want to support versions of Python older than 3.5, try this:

from sys import version_info
if version_info[0] < 3:
    pass # Python 2 has built in reload
elif version_info[0] == 3 and version_info[1] <= 4:
    from imp import reload # Python 3.0 - 3.4 
else:
    from importlib import reload # Python 3.5+

To use it, run reload(MODULE), replacing MODULE with the module you want to reload.

For example, reload(math) will reload the math module.

Ram Narasimhan explained the concept very nicely here below is an alternative explanation through the code example of Naive Bayes in action
It uses an example problem from this book on page 351
This is the data set that we will be using

In the above dataset if we give the hypothesis = {"Age":'<=30', "Income":"medium", "Student":'yes' , "Creadit_Rating":'fair'} then what is the probability that he will buy or will not buy a computer.
The code below exactly answers that question.
Just create a file called named new_dataset.csv and paste the following content.

Age,Income,Student,Creadit_Rating,Buys_Computer
<=30,high,no,fair,no
<=30,high,no,excellent,no
31-40,high,no,fair,yes
>40,medium,no,fair,yes
>40,low,yes,fair,yes
>40,low,yes,excellent,no
31-40,low,yes,excellent,yes
<=30,medium,no,fair,no
<=30,low,yes,fair,yes
>40,medium,yes,fair,yes
<=30,medium,yes,excellent,yes
31-40,medium,no,excellent,yes
31-40,high,yes,fair,yes
>40,medium,no,excellent,no

Not Bootstrap specific really... You can use inline styles or define a custom class to specify the desired "background-color".

On the other hand, Bootstrap does have a few built in background colors that have semantic meaning like "bg-success" (green) and "bg-danger" (red).

I encountered this issue in a NodeJS Lambda function that was triggered by a file upload to S3.

My mistake was that I was not decoding the object key, which contained a colon. Corrected my code as follows:

let key = decodeURIComponent(event.Records[0].s3.object.key);

In order to delete a cookie set the expires date to something in the past. A function that does this would be.

var delete_cookie = function(name) {
    document.cookie = name + '=;expires=Thu, 01 Jan 1970 00:00:01 GMT;';
};

Then to delete a cookie named roundcube_sessauth just do.

delete_cookie('roundcube_sessauth');

since iOS 10 you should use:

guard let url = URL(string: linkUrlString) else {
    return
}
    
if #available(iOS 10.0, *) {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
    UIApplication.shared.openURL(url)
}

You need to use cast. I see the other answers, and they will really work, but as the tag is C++ I'd suggest you to use static_cast:

float m = static_cast< float >( a.y - b.y ) / static_cast< float >( a.x - b.x );

The simplest approach is to use the atoi() function found in stdlib.h:

CString s = "123";
int x = atoi( s );

However, this does not deal well with the case where the string does not contain a valid integer, in which case you should investigate the strtol() function:

CString s = "12zzz";    // bad integer
char * p;
int x = strtol ( s, & p, 10 );
if ( * p != 0 ) {
   // s does not contain an integer
}

Ok, try this:

Get the image with the transparent circle - http://i39.tinypic.com/15s97vd.png Put that image in a html element and change that element's background color via css. This way you get the logo with the circle in the color defined in the stylesheet.

The html

<div class="badassColorChangingLogo">
    <img src="http://i39.tinypic.com/15s97vd.png" /> 
    Or download the image and change the path to the downloaded image in your machine
</div>

The css

div.badassColorChangingLogo{
    background-color:white;
}
div.badassColorChangingLogo:hover{
    background-color:blue;
}

Keep in mind that this wont work on non-alpha capable browsers like ie6, and ie7. for ie you can use a js fix. Google ddbelated png fix and you can get the script.

I like to use presence, inspired from Ruby on Rails:

$.fn.presence = function () {
    return this.length !== 0 && this;
}

Your example becomes:

alert($('#notAnElement').presence() || "No object found");

I find it superior to the proposed $.fn.exists because you can still use boolean operators or if, but the truthy result is more useful. Another example:

$ul = $elem.find('ul').presence() || $('<ul class="foo">').appendTo($elem)
$ul.append('...')

You say you have a database on PhpMyAdmin, so you are using MySQL. PHP provides functions for connecting to a MySQL database.

$connection = mysql_connect('localhost', 'root', ''); //The Blank string is the password
mysql_select_db('hrmwaitrose');

$query = "SELECT * FROM employee"; //You don't need a ; like you do in SQL
$result = mysql_query($query);

echo "<table>"; // start a table tag in the HTML

while($row = mysql_fetch_array($result)){   //Creates a loop to loop through results
echo "<tr><td>" . $row['name'] . "</td><td>" . $row['age'] . "</td></tr>";  //$row['index'] the index here is a field name
}

echo "</table>"; //Close the table in HTML

mysql_close(); //Make sure to close out the database connection

In the while loop (which runs every time we encounter a result row), we echo which creates a new table row. I also add a to contain the fields.

This is a very basic template. You see the other answers using mysqli_connect instead of mysql_connect. mysqli stands for mysql improved. It offers a better range of features. You notice it is also a little bit more complex. It depends on what you need.

Try this JavaScript code:

function printout() {

    var newWindow = window.open();
    newWindow.document.write(document.getElementById("output").innerHTML);
    newWindow.print();
}

"2014-01-01T23:28:56.782Z"

The date is represented in a standard and sortable format that represents a UTC time (indicated by the Z). ISO 8601 also supports time zones by replacing the Z with + or – value for the timezone offset:

"2014-02-01T09:28:56.321-10:00"

There are other variations of the timezone encoding in the ISO 8601 spec, but the –10:00 format is the only TZ format that current JSON parsers support. In general it’s best to use the UTC based format (Z) unless you have a specific need for figuring out the time zone in which the date was produced (possible only in server side generation).

NB:

    var date = new Date();
    console.log(date); // Wed Jan 01 2014 13:28:56 GMT- 
    1000 (Hawaiian Standard Time) 
        
    var json = JSON.stringify(date);
    console.log(json);  // "2014-01-01T23:28:56.782Z"

To tell you that's the preferred way even though JavaScript doesn't have a standard format for it

// JSON encoded date
var json = "\"2014-01-01T23:28:56.782Z\"";

var dateStr = JSON.parse(json);  
console.log(dateStr); // 2014-01-01T23:28:56.782Z

I'm assuming windows here. So, you'll need to use WMI to get that information. Check out The Scripting Guy's archives for a lot of examples on how to use WMI from a script.

Option A

If your install isn't already damaged, you can drop unwanted PostgreSQL servers ("clusters") using pg_dropcluster. Use that in preference to a full purge and reinstall if you just want to restart with a fresh PostgreSQL instance.

$ pg_lsclusters
Ver Cluster Port Status Owner    Data directory              Log file
11  main    5432 online postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
$ sudo systemctl stop postgresql@11-main
$ sudo pg_dropcluster --stop 11 main
$ sudo pg_createcluster --start 11 main

Option B

If you really need to do a full purge and reinstall, first make sure PostgreSQL isn't running. ps -C postgres should show no results.

Now run:

apt-get --purge remove postgresql\*

to remove everything PostgreSQL from your system. Just purging the postgres package isn't enough since it's just an empty meta-package.

Once all PostgreSQL packages have been removed, run:

rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres

You should now be able to:

apt-get install postgresql

or for a complete install:

apt-get install postgresql-8.4 postgresql-contrib-8.4 postgresql-doc-8.4

It is not too surprising: the execution plan for the tiny insert is computed once, and then reused 1000 times. Parsing and preparing the plan is quick, because it has only four values to del with. A 1000-row plan, on the other hand, needs to deal with 4000 values (or 4000 parameters if you parameterized your C# tests). This could easily eat up the time savings you gain by eliminating 999 roundtrips to SQL Server, especially if your network is not overly slow.

You mentioned a signed angle (-90). In many applications angles may have signs (positive and negative, see http://en.wikipedia.org/wiki/Angle). If the points are (say) P2(1,0), P1(0,0), P3(0,1) then the angle P3-P1-P2 is conventionally positive (PI/2) whereas the angle P2-P1-P3 is negative. Using the lengths of the sides will not distinguish between + and - so if this matters you will need to use vectors or a function such as Math.atan2(a, b).

Angles can also extend beyond 2*PI and while this is not relevant to the current question it was sufficiently important that I wrote my own Angle class (also to make sure that degrees and radians did not get mixed up). The questions as to whether angle1 is less than angle2 depends critically on how angles are defined. It may also be important to decide whether a line (-1,0)(0,0)(1,0) is represented as Math.PI or -Math.PI

What you've got (according to the debug image) is an object array containing a string array. So you need something like:

Object[] objects = (Object[]) values;
String[] strings = (String[]) objects[0];

You haven't shown the type of values - if this is already Object[] then you could just use (String[])values[0].

Of course even with the cast to Object[] you could still do it in one statement, but it's ugly:

String[] strings = (String[]) ((Object[])values)[0];

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

There is no completely portable solution.

Question 19.1 of the comp.lang.c FAQ covers this in some depth, with solutions for Windows, Unix-like systems, and even MS-DOS and VMS.

A quick and incomplete summary:

• You can use the curses library; call cbreak() followed by getch() (not to be confused with the Windows-specific getch()function). Note that curses generally takes control of the terminal, so this is likely to be overkill.
• You might be able to use ioctl() to manipulate the terminal settings.
• On POSIX-compliant systems, tcgetattr() and tcsetattr() may be a better solution.
• On Unix, you can use system() to invoke the stty command.
• On MS-DOS, you can use getch() or getche().
• On VMS (now called OpenVMS), the Screen Management (SMG$) routines might do the trick.

All these C solutions should work equally well in C++; I don't know of any C++-specific solution.

Try to use document.createEvent described here https://developer.mozilla.org/en-US/docs/Web/API/document.createEvent

The code for function that simulates click should look something like this:

function simulateClick() {
  var evt = document.createEvent("MouseEvents");
  evt.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);
  var a = document.getElementById("gift-close"); 
  a.dispatchEvent(evt);      
}

Years after everyone's answer, I too want to present how I did it for my project

To access any element of a list in a YAML file like this:

global:
  registry:
    url: dtr-:5000/
    repoPath:
  dbConnectionString: jdbc:oracle:thin:@x.x.x.x:1521:abcd

You can use following python script:

import yaml

with open("/some/path/to/yaml.file", 'r') as f:
    valuesYaml = yaml.load(f, Loader=yaml.FullLoader)

print(valuesYaml['global']['dbConnectionString'])

Distinct and Group By generally do the same kind of thing, for different purposes... They both create a 'working" table in memory based on the columns being Grouped on, (or selected in the Select Distinct clause) - and then populate that working table as the query reads data, adding a new "row" only when the values indicate the need to do so...

The only difference is that in the Group By there are additional "columns" in the working table for any calculated aggregate fields, like Sum(), Count(), Avg(), etc. that need to updated for each original row read. Distinct doesn't have to do this... In the special case where you Group By only to get distinct values, (And there are no aggregate columns in output), then it is probably exactly the same query plan.... It would be interesting to review the query execution plan for the two options and see what it did...

Certainly Distinct is the way to go for readability if that is what you are doing (When your purpose is to eliminate duplicate rows, and you are not calculating any aggregate columns)

As an alternative, you can install 7.1 version of mcrypt and create a symbolic link to it:

Install php7.1-mcrypt:

sudo apt install php7.1-mcrypt

Create a symbolic link:

sudo ln -s /etc/php/7.1/mods-available/mcrypt.ini /etc/php/7.2/mods-available

After enabling mcrypt by sudo phpenmod mcrypt, it gets available.

Depends, Do you need the data to be loaded each time you open the view? or only once?

• Red : They don't require to change every time. Once they are loaded they stay as how they were.
• Purple: They need to change over time or after you load each time. You don't want to see the same 3 suggested users to follow, it needs to be reloaded every time you come back to the screen. Their photos may get updated... you don't want to see a photo from 5 years ago...

viewDidLoad: Whatever processing you have that needs to be done once.
viewWilLAppear: Whatever processing that needs to change every time the page is loaded.

Labels, icons, button titles or most dataInputedByDeveloper usually don't change. Names, photos, links, button status, lists (input Arrays for your tableViews or collectionView) or most dataInputedByUser usually do change.

You need to include inttypes.h if you want all those nifty new format specifiers for the intN_t types and their brethren, and that is the correct (ie, portable) way to do it, provided your compiler complies with C99. You shouldn't use the standard ones like %d or %u in case the sizes are different to what you think.

It includes stdint.h and extends it with quite a few other things, such as the macros that can be used for the printf/scanf family of calls. This is covered in section 7.8 of the ISO C99 standard.

For example, the following program:

#include <stdio.h>
#include <inttypes.h>
int main (void) {
    uint32_t a=1234;
    uint16_t b=5678;
    printf("%" PRIu32 "\n",a);
    printf("%" PRIu16 "\n",b);
    return 0;
}

outputs:

1234
5678

You can use both. The css style will override the size attribute in browsers that support CSS and make the field the correct width, and for those that don't, it will fall back to the specified number of characters.

Edit: I should have mentioned that the size attribute isn't a precise method of sizing: according to the HTML specification, it should refer to the number of characters of the current font the input will be able to display at once.

However, unless the font specified is a fixed-width/monospace font, this is not a guarantee that the specified number of characters will actually be visible; in most fonts, different characters will be different widths. This question has some good answers relating to this issue.

The snippet below demonstrates both approaches.

Do you have ROWS of data (horizontal) as you stated or COLUMNS (vertical)?

If it's the latter you can use "Text to columns" functionality to convert a whole column "in situ" - to do that:

Select column > Data > Text to columns > Next > Next > Choose "Date" under "column data format" and "YMD" from dropdown > Finish

....otherwise you can convert with a formula by using

=TEXT(A1,"0000-00-00")+0

and format in required date format

The main problem for causing your table unable to migrate, is that you have running query on your "AppServiceProvider.php" try to check your serviceprovider and disable code for the meantime, and run php artisan migrate

Use this code

Environment.Exit(0);

use 0 as the int if you don't want to return anything.

Java lacks coalesce operator, so your code with an explicit temporary is your best choice for an assignment with a single call.

You can use the result variable as your temporary, like this:

dinner = ((dinner = cage.getChicken()) != null) ? dinner : getFreeRangeChicken();

This, however, is hard to read.

You can set GIT_SSL_NO_VERIFY to true:

GIT_SSL_NO_VERIFY=true git clone https://example.com/path/to/git

or alternatively configure Git not to verify the connection on the command line:

git -c http.sslVerify=false clone https://example.com/path/to/git

Note that if you don't verify SSL/TLS certificates, then you are susceptible to MitM attacks.

There are some other ways too. I have used the following script:

$File = "D:\Dev\somefilename.zip";
$ftp = "ftp://username:[email protected]/pub/incoming/somefilename.zip";

Write-Host -Object "ftp url: $ftp";

$webclient = New-Object -TypeName System.Net.WebClient;
$uri = New-Object -TypeName System.Uri -ArgumentList $ftp;

Write-Host -Object "Uploading $File...";

$webclient.UploadFile($uri, $File);

And you could run a script against the windows FTP command line utility using the following command

ftp -s:script.txt 

(Check out this article)

The following question on SO also answers this: How to script FTP upload and download?

You can also import as

from math import *

Then you can use any mathematical function without prefixing math. e.g.

sqrt(4)

Definitely avoid using eval to do something like this, or you will open yourself to XSS (Cross-Site Scripting) vulnerabilities.

For example, if you were to use the eval solutions proposed here, a nefarious user could send a link to their victim that looked like this:

http://yoursite.com/foo.html?func=function(){alert('Im%20In%20Teh%20Codez');}

And their javascript, not yours, would get executed. This code could do something far worse than just pop up an alert of course; it could steal cookies, send requests to your application, etc.

So, make sure you never eval untrusted code that comes in from user input (and anything on the query string id considered user input). You could take user input as a key that will point to your function, but make sure that you don't execute anything if the string given doesn't match a key in your object. For example:

// set up the possible functions:
var myFuncs = {
  func1: function () { alert('Function 1'); },
  func2: function () { alert('Function 2'); },
  func3: function () { alert('Function 3'); },
  func4: function () { alert('Function 4'); },
  func5: function () { alert('Function 5'); }
};
// execute the one specified in the 'funcToRun' variable:
myFuncs[funcToRun]();

This will fail if the funcToRun variable doesn't point to anything in the myFuncs object, but it won't execute any code.

I Know this is an old topic...but none of the above helped me. And after searching a lot and trying everything...I came up with this.

First remove the click code out of the $(document).ready part and put it in a separate section. then put your click code in an $(function(){......}); code.

Like this:

<script>
  $(function(){
    //your click code
    $("a.tabclick").on('click',function() {
      //do something
    });
  });
</script>

Should use this solution as a last choice, when other solutions don't work.

Original answer:

    memset(&ifr, 0, sizeof(ifr));

    fd = socket(AF_INET, SOCK_DGRAM, 0);

    ifr.ifr_addr.sa_family = AF_INET;
    strncpy(ifr.ifr_name , iface , IFNAMSIZ-1);

    if (0 == ioctl(fd, SIOCGIFHWADDR, &ifr)) {
        mac = (unsigned char *)ifr.ifr_hwaddr.sa_data;

I think this example explains clearly the differences between inheritance and composition.

In this exmple, the problem is solved using inheritance and composition. The author pays attention to the fact that ; in inheritance, a change in superclass might cause problems in derived class, that inherit it.

There you can also see the difference in representation when you use a UML for inheritance or composition.

I will soon released a new version of my app to support to galaxy ace.

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

I spent a ridiculous amount of time trying to figure this problem out for several pages of a new site I'm developing and nothing seemed to work (including any of the various solutions presented above that I implemented. I'm guessing jQuery has just changed things up enough since they were suggested that the solutions dont' work any longer. I don't know. Honestly, I don't understand why there isn't something simple implemented into the jQuery ui to configure this, as it seems to be a fairly large issue with the calendar always popping up at some position considerably far down the page from the input to which it is attached.

Anyhow, I wanted an end solution that was generic enough that I could use it anywhere and it would work. I seem to have finally come to a conclusion that avoids some of the more complicated and jQuery-code-specific answers above:

jsFiddle: http://jsfiddle.net/mu27tLen/

HTML:

<input type="text" class="datePicker" />

JS:

positionDatePicker= function(cssToAdd) {
    /* Remove previous positioner */
    var oldScript= document.getElementById('datePickerPosition');
    if(oldScript) oldScript.parentNode.removeChild(oldScript);
    /* Create new positioner */
    var newStyle= document.createElement("style");
    newStyle.type= 'text/css';
    newStyle.setAttribute('id', 'datePickerPostion');
    if(newStyle.styleSheet) newStyle.styleSheet.cssText= cssToAdd;
    else newStyle.appendChild(document.createTextNode(cssToAdd));
    document.getElementsByTagName("head")[0].appendChild(newStyle);
}
jQuery(document).ready(function() {
    /* Initialize date picker elements */
    var dateInputs= jQuery('input.datePicker');
    dateInputs.datepicker();
    dateInputs.datepicker('option', {
        'dateFormat' : 'mm/dd/yy',
        'beforeShow' : function(input, inst) {
            var bodyRect= document.body.getBoundingClientRect();
            var rect= input.getBoundingClientRect();
            positionDatePicker('.page #ui-datepicker-div{z-index:100 !important;top:' + (rect.top - bodyRect.top + input.offsetHeight + 2) + 'px !important;}');
        }
    }).datepicker('setDate', new Date());
});

Essentially I attach a new style tag to the head prior to every datepicker "show" event (deleting the previous one, if present). This method of doing things gets around a large majority of the issues that I ran into during development.

Tested on Chrome, Firefox, Safari, and IE>8 (as IE8 doesn't work well with jsFiddle and I'm losing my gusto for caring about

I know that this is a mix of jQuery and javascript contexts, but at this point I just don't want to put the effort into converting it to jQuery. Would be simple, I know. I'm so done with this thing right now. Hope someone else can benefit from this solution.

The combination of both answers. Also prints a method name:

Class thisClass = new Object(){}.getClass();
String className = thisClass.getEnclosingClass().getSimpleName();
String methodName = thisClass.getEnclosingMethod().getName();
Log.d("app", className + ":" + methodName);

There is a new (sometime pre April 2013) option on the site that says "Clone in Windows".

This works very nicely if you already have the Windows GitHub Client as mentioned by @Tommy in his answer on this related question (How to download source in ZIP format from GitHub?).

Sometimes the Maven command line is sufficient when scripting something related to the project version, e.g. for artifact retrieval via URL from a repository:

mvn help:evaluate -Dexpression=project.version -q -DforceStdout

Usage example:

VERSION=$( mvn help:evaluate -Dexpression=project.version -q -DforceStdout )
ARTIFACT_ID=$( mvn help:evaluate -Dexpression=project.artifactId -q -DforceStdout )
GROUP_ID_URL=$( mvn help:evaluate -Dexpression=project.groupId -q -DforceStdout | sed -e 's#\.#/#g' )
curl -f -S -O http://REPO-URL/mvn-repos/${GROUP_ID_URL}/${ARTIFACT_ID}/${VERSION}/${ARTIFACT_ID}-${VERSION}.jar

I fixed my error. just removed "Value" from this line:

If drv.Item("Quantity").Value < 5  Then

So it will look like

If drv.Item("Quantity") < 5 Then

I have a ZTE Crescent phone (Orange San Francisco II).

When I connect the phone to the USB a disk shows up in OS X named 'ZTE_USB_Driver'.

Running adb devices displays no connected devices. But after I eject the 'ZTE_USB_Driver' disk from OS X, and run adb devices again the phone shows up as connected.

After few years, I moved to leaflet map and I have fixed this issue completely, the following could be applied to google maps too:

    var headerHeight = $("#navMap").outerHeight();
    var footerHeight = $("footer").outerHeight();
    var windowHeight = window.innerHeight;
    var mapContainerHeight = headerHeight + footerHeight;
    var totalMapHeight = windowHeight - mapContainerHeight;
    $("#map").css("margin-top", headerHeight);
    $("#map").height(totalMapHeight);

    $(window).resize(function(){
        var headerHeight = $("#navMap").outerHeight();
        var footerHeight = $("footer").outerHeight();
        var windowHeight = window.innerHeight;
        var mapContainerHeight = headerHeight + footerHeight;
        var totalMapHeight = windowHeight - mapContainerHeight;
        $("#map").css("margin-top", headerHeight);
        $("#map").height(totalMapHeight);
        map.fitBounds(group1.getBounds());
    });

If java command is working and getting problem with javac. then first check in jdk's bin directory javac.exe file is there or not. If javac.exe file is exist then set JAVA_HOME as System variable.

You can also use regular expressions:

SELECT * FROM Parameters WHERE Name REGEXP '\n';

I'm assuming the problem is that they are wrapping onto separate lines when the window is too narrow. As others have pointed out, by default the label and input should be "display:inline;", so unless you have other style rules that are changing this, they should render on the same line if there is room.

Without changing the markup, there will be no way to fix this using only CSS.

The simplest way to fix it would be to wrap the radio button and label in a block element, such as a p or a div, and then prevent that from wrapping by using white-space:nowrap. For example:

<div style="white-space:nowrap;">
  <label for="one">First Item</label>
  <input type="radio" id="one" name="first_item" value="1" />
</div>

If you're still facing the issue even after replacing doGet() with doPost() and changing the form method="post". Try clearing the cache of the browser or hit the URL in another browser or incognito/private mode. It may works!

ProjectCodeMeter counts LLOC (logical lines of code) exactly as you described (only effective lines). it integrates into eclipse as external code metrics tool, it's not real-time though, it generates a report.actually it counts many source code metrics such as complexity, arithmetic intricacy, hard coded strings, numeric constants.. even estimates development time in hours.

TreeSet would not work because they do not allow duplicates plus they do not provide method to fetch element at specific position. PriorityQueue would not work because it does not allow fetching elements at specific position which is a basic requirement for a list. I think you need to implement your own algorithm to maintain a sorted list in Java with O(logn) insert time, unless you do not need duplicates. Maybe a solution could be using a TreeMap where the key is a subclass of the item overriding the equals method so that duplicates are allowed.

Do right mouse click on your project, then select 'Open Module Settings' - then you can add modules to your project..

Select count(1) From V$session
where status='ACTIVE'

The other answers here are very much correct, and valuable. But sometimes you just want simple: to get a plain old parsed value at directive instantiation, without needing updates, and without messing with isolate scope. For instance, it can be handy to provide a declarative payload into your directive as an array or hash-object in the form:

my-directive-name="['string1', 'string2']"

In that case, you can cut to the chase and just use a nice basic angular.$eval(attr.attrName).

element.val("value = "+angular.$eval(attr.value));

Working Fiddle.

The best solution is to override the click functionality:

public void _click(WebElement element){
    boolean flag = false;
    while(true) {
        try{
            element.click();
            flag=true;
        }
        catch (Exception e){
            flag = false;
        }
        if(flag)
        {
            try{
                element.click();
            }
            catch (Exception e){
                System.out.printf("Element: " +element+ " has beed clicked, Selenium exception triggered: " + e.getMessage());
            }
            break;
        }
    }
}

To those who are stuck wondering why a window flashes and goes away without doing anything, the problem may related to the RELATIVE path in your Python script. e.g. you used ".\". Even the Python script and Excel Workbook is in the same directory, the Current Directory may still be different. If you don't want to modify your code to change it to an absolute path. Just change your current Excel directory before you run the python script by:

ChDir ActiveWorkbook.Path

I'm just giving a example here. If the flash do appear, one of the first issues to check is the Current Working Directory.

Give this a try:

<!DOCTYPE html>
<html>
<head>
    <title>List Test</title>
    <style>
        li:hover {
            cursor: hand; cursor: pointer;
        }
    </style>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script>
        $(document).ready(function(){
            $("li").click(function(){
                $('#alltext').append($(this).text());
            });
        });
    </script>
</head>
<body>

    <h2>List items</h2>
    <ol>
        <li>Hello</li>
        <li>World</li>
        <li>Earthlings</li>
    </ol>
    <form>
        <textarea id="alltext"></textarea>
    </form>

</body>
</html>

you need only set default value to parameters(you do not need the Route attribute):

public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

reVerse's answer is great but it didn't point out how to remove the floating error tooltip kind of thing

You'll need edittext.setError(null) to remove that.
Also, as someone pointed out, you don't need TextInputLayout.setErrorEnabled(true)

Layout

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <EditText
        android:id="@+id/edittext"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter something" />
</android.support.design.widget.TextInputLayout>

Code

TextInputLayout til = (TextInputLayout) editText.getParent();
til.setError("Your input is not valid...");
editText.setError(null);

An Internet Information Services (IIS) worker process is a windows process (w3wp.exe) which runs Web applications, and is responsible for handling requests sent to a Web Server for a specific application pool.

It is the worker process for IIS. Each application pool creates at least one instance of w3wp.exe and that is what actually processes requests in your application. It is not dangerous to attach to this, that is just a standard windows message.

@tokland

tried your code and corrected it for 3.4 and windows dir.cmd is a simple dir command, saved as cmd-file

import subprocess
c = "dir.cmd"

def execute(command):
    popen = subprocess.Popen(command, stdout=subprocess.PIPE,bufsize=1)
    lines_iterator = iter(popen.stdout.readline, b"")
    while popen.poll() is None:
        for line in lines_iterator:
            nline = line.rstrip()
            print(nline.decode("latin"), end = "\r\n",flush =True) # yield line

execute(c)

I came across the same problem, and found that easier way is to undock the developer tool's video to a separate window! (Using the right hand top corner toolbar button of developer tools window) and in the new window , simply say select all and copy and paste to excel!!

I just wrote this helper function. Put it in App_Code/JS.cshtml:

@using System.Web.Script.Serialization
@helper Encode(object obj)
{
    @(new HtmlString(new JavaScriptSerializer().Serialize(obj)));
}

Then in your example, you can do something like this:

var title = @JS.Encode(Model.Title);

Notice how I don't put quotes around it. If the title already contains quotes, it won't explode. Seems to handle dictionaries and anonymous objects nicely too!

This works for me - i am using jackson 2.0.4

ObjectMapper objectMapper = new ObjectMapper();
final DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
objectMapper.setDateFormat(df);

you cant do this. Use a custom popup. Something like with the help of jQuery UI or jQuery BOXY.

SELECT DATENAME(DW,CONVERT(VARCHAR(20),GETDATE(),101))

The variable name you're looking for is ansible_ssh_private_key_file.

You should set it at 'vars' level:

• in the inventory file:

  myHost ansible_ssh_private_key_file=~/.ssh/mykey1.pem
  myOtherHost ansible_ssh_private_key_file=~/.ssh/mykey2.pem
  

• in the host_vars:

  # hosts_vars/myHost.yml
  ansible_ssh_private_key_file: ~/.ssh/mykey1.pem
  
  # hosts_vars/myOtherHost.yml
  ansible_ssh_private_key_file: ~/.ssh/mykey2.pem
  

• in a group_vars file if you use the same key for a group of hosts

• in the vars section of your play:

  - hosts: myHost
    remote_user: ubuntu
    vars_files:
      - vars.yml
    vars:
      ansible_ssh_private_key_file: "{{ key1 }}"
    tasks:
      - name: Echo a hello message
        command: echo hello

1. Function imageMorph will create a new img element therefore the id is removed. Changed to

   $("#wrapper > img")

2. You should use live() function for click event if you want you rocket lanch again.

Don't forget to take into consideration the global flag in your regexp :

var reg = /abc/g;
!!'abcdefghi'.match(reg); // => true
!!'abcdefghi'.match(reg); // => true
reg.test('abcdefghi');    // => true
reg.test('abcdefghi');    // => false <=

This is because Regexp keeps track of the lastIndex when a new match is found.

I think the one of the easiest ways out would be to parse the string returned by URL.getQuery() as

public static Map<String, String> getQueryMap(String query) {  
    String[] params = query.split("&");  
    Map<String, String> map = new HashMap<String, String>();

    for (String param : params) {  
        String name = param.split("=")[0];  
        String value = param.split("=")[1];  
        map.put(name, value);  
    }  
    return map;  
}

You can use the map returned by this function to retrieve the value keying in the parameter name.

Is your server single-threaded? If so, what polling / multiplexing function are you using?

Using select() does not work beyond the hard-coded maximum file descriptor limit set at compile-time, which is hopeless (normally 256, or a few more).

poll() is better but you will end up with the scalability problem with a large number of FDs repopulating the set each time around the loop.

epoll() should work well up to some other limit which you hit.

10k connections should be easy enough to achieve. Use a recent(ish) 2.6 kernel.

How many client machines did you use? Are you sure you didn't hit a client-side limit?

you can use Realm or Sqlite if you want to manage complex data type.

Otherwise go with inbuilt react native asynstorage

            var LatLongs    =   LatLongsObject;

            var lat = LatLongs.k;
            var lon = LatLongs.B;
           console.log("Lat is: "+lat+" Long is: "+lon); //do something with the coordinates

        });

Generally you compile most .c files in the following way:

gcc foo.c -o foo. It might vary depending on what #includes you used or if you have any external .h files. Generally, when you have a C file, it looks somewhat like the following:

#include <stdio.h>
    /* any other includes, prototypes, struct delcarations... */
    int main(){
    */ code */
}

When I get an 'undefined reference to main', it usually means that I have a .c file that does not have int main() in the file. If you first learned java, this is an understandable manner of confusion since in Java, your code usually looks like the following:

//any import statements you have
public class Foo{
    int main(){}
 }

I would advise looking to see if you have int main() at the top.

Java and Kotlin runs on Java Virtual Machine (JVM).

Converting a Kotlin file to Java file involves two steps i.e. compiling the Kotlin code to the JVM bytecode and then decompile the bytecode to the Java code.

Steps to convert your Kotlin source file to Java source file:

1. Open your Kotlin project in the Android Studio.
2. Then navigate to Tools -> Kotlin -> Show Kotlin Bytecode.

3. You will get the bytecode of your Kotin file.
4. Now click on the Decompile button to get your Java code from the bytecode

In Android Manifest File, put attribute for your <activity> that android:screenOrientation="portrait"

Looking at the implementation differences, I see that:

MDC on encodeURIComponent():

• literal characters (regex representation): [-a-zA-Z0-9._*~'()!]

Java 1.5.0 documentation on URLEncoder:

• literal characters (regex representation): [-a-zA-Z0-9._*]
• the space character " " is converted into a plus sign "+".

So basically, to get the desired result, use URLEncoder.encode(s, "UTF-8") and then do some post-processing:

• replace all occurrences of "+" with "%20"
• replace all occurrences of "%xx" representing any of [~'()!] back to their literal counter-parts

I think the largely correct way, is to set css to this:

html
{
    overflow: hidden;
}

body
{
    margin: 0;
    box-sizing: border-box;
}

html, body
{
    height: 100%;
}

@Temporal is a JPA annotation which can be used to store in the database table on of the following column items:

1. DATE (java.sql.Date)
2. TIME (java.sql.Time)
3. TIMESTAMP (java.sql.Timestamp)

Generally when we declare a Date field in the class and try to store it.
It will store as TIMESTAMP in the database.

@Temporal
private Date joinedDate;

Above code will store value looks like 08-07-17 04:33:35.870000000 PM

If we want to store only the DATE in the database,
We can use/define TemporalType.

@Temporal(TemporalType.DATE)
private Date joinedDate;

This time, it would store 08-07-17 in database

There are some other attributes as well as @Temporal which can be used based on the requirement.

isNumber = function(obj, strict) {
    var strict = strict === true ? true : false;
    if (strict) {
        return !isNaN(obj) && obj instanceof Number ? true : false;
    } else {
        return !isNaN(obj - parseFloat(obj));
    }
}

output without strict mode:

var num = 14;
var textnum = '14';
var text = 'yo';
var nan = NaN;

isNumber(num);
isNumber(textnum);
isNumber(text);
isNumber(nan);

true
true
false
false

output with strict mode:

var num = 14;
var textnum = '14';
var text = 'yo';
var nan = NaN;

isNumber(num, true);
isNumber(textnum, true);
isNumber(text, true);
isNumber(nan);

true
false
false
false

You can force bundler to use the gems you deploy using "bundle package" and "bundle install --local"

On your development machine:

bundle install

(Installs required gems and makes Gemfile.lock)

bundle package

(Caches the gems in vendor/cache)

On the server:

bundle install --local

(--local means "use the gems from vendor/cache")

Why haven't you tried httplib.HTTPSConnection? It doesn't do SSL validation but this isn't required to connect over https. Your code works fine with https connection:

>>> import httplib
>>> conn = httplib.HTTPSConnection("mail.google.com")
>>> conn.request("GET", "/")
>>> r1 = conn.getresponse()
>>> print r1.status, r1.reason
200 OK

Running the risk of getting another Necromancer badge, I would like to add one very good use for uintptr_t (or even intptr_t) and that is writing testable embedded code. I write mostly embedded code targeted at various arm and currently tensilica processors. These have various native bus width and the tensilica is actually a Harvard architecture with separate code and data buses that can be different widths. I use a test driven development style for much of my code which means I do unit tests for all the code units I write. Unit testing on actual target hardware is a hassle so I typically write everything on an Intel based PC either in Windows or Linux using Ceedling and GCC. That being said, a lot of embedded code involves bit twiddling and address manipulations. Most of my Intel machines are 64 bit. So if you are going to test address manipulation code you need a generalized object to do math on. Thus the uintptr_t give you a machine independent way of debugging your code before you try deploying to target hardware. Another issue is for the some machines or even memory models on some compilers, function pointers and data pointers are different widths. On those machines the compiler may not even allow casting between the two classes, but uintptr_t should be able to hold either. -- Edit -- Was pointed out by @chux, this is not part of the standard and functions are not objects in C. However it usually works and since many people don't even know about these types I usually leave a comment explaining the trickery. Other searches in SO on uintptr_t will provide further explanation. Also we do things in unit testing that we would never do in production because breaking things is good.

I found that the answer by cballou was no longer working in Firefox as of Jan. 2014. Specifically, if (self.pageYOffset) didn't trigger if the client had scrolled right, but not down - because 0 is a falsey number. This went undetected for a while because Firefox supported document.body.scrollLeft/Top, but this is no longer working for me (on Firefox 26.0).

Here's my modified solution:

var getPageScroll = function(document_el, window_el) {
  var xScroll = 0, yScroll = 0;
  if (window_el.pageYOffset !== undefined) {
    yScroll = window_el.pageYOffset;
    xScroll = window_el.pageXOffset;
  } else if (document_el.documentElement !== undefined && document_el.documentElement.scrollTop) {
    yScroll = document_el.documentElement.scrollTop;
    xScroll = document_el.documentElement.scrollLeft;
  } else if (document_el.body !== undefined) {// all other Explorers
    yScroll = document_el.body.scrollTop;
    xScroll = document_el.body.scrollLeft;
  }
  return [xScroll,yScroll];
};

Tested and working in FF26, Chrome 31, IE11. Almost certainly works on older versions of all of them.

I had this same error, I had a input field named control in my custom Form Component but was accidentally passing control in input named formControl. Hope no one faces that issue.

Your date object is probably ok, since you sent your date encoded in ISO format with GMT timezone and you are in EST when you print your date.

Note that Date objects perform timezone translation at the moment they are printed. You can check if your date object is correct with:

Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
cal.setTime(date);
System.out.println (cal);

I think the parent Container needs to be given a maxWidth of the proper size. It looks like the Text box will fill whatever space it is given above.

  for(var i = 0; i < BoardMessages.length;i++){
        (function(j){
            console.log("Loading message %d".green, j);
            htmlMessageboardString += MessageToHTMLString(BoardMessages[j]);
        })(i);
  }

That should work; however, you should never create a function in a loop. Therefore,

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

  function composeMessage(message){
      console.log("Loading message %d".green, message);
      htmlMessageboardString += MessageToHTMLString(message);
  }

maybe useful for somebody, I got next problem on windows 8, apache 2.4, php 7+.

php.ini conf>

extension_dir="C:/Server/PHP7/ext"

php on apache works ok but on cli problem with libs loading, as a result, I changed to

extension_dir="C:/server/PHP7/ext"

i accomplished this with the install command on linux:

root@logstash:# myfile=bash_history.log.2021-02-04.gz ; install -v -p -D $myfile /tmp/a/b/$myfile

bash_history.log.2021-02-04.gz -> /tmp/a/b/bash_history.log.2021-02-04.gz

the only downside being the file permissions are changed:

root@logstash:# ls -lh /tmp/a/b/

-rwxr-xr-x 1 root root 914 Fev  4 09:11 bash_history.log.2021-02-04.gz

if you dont mind resetting the permission, you can use:

-g, --group=GROUP   set group ownership, instead of process' current group
-m, --mode=MODE     set permission mode (as in chmod), instead of rwxr-xr-x
-o, --owner=OWNER   set ownership (super-user only)

I use a NAnt Build Script to deploy to my different environments. I have it modify my config files via XPath depending on where they're being deployed to, and then it automagically puts them into that environment using Beyond Compare.

Takes a minute or two to setup, but you only need to do it once. Then batch files take over while I go get another cup of coffee. :)

Here's an article I found on it.

If the goal is to have a reusable RestTemplate which is in general useful for attaching the same header to a series of similar request a org.springframework.boot.web.client.RestTemplateCustomizer parameter can be used with a RestTemplateBuilder:

 String accessToken= "<the oauth 2 token>";
 RestTemplate restTemplate = new RestTemplateBuilder(rt-> rt.getInterceptors().add((request, body, execution) -> {
        request.getHeaders().add("Authorization", "Bearer "+accessToken);
        return execution.execute(request, body);
    })).build();

you can try this

class select_choice():
    return x, y

a, b = test()

Angular 1.1.5 added support for ternary operators:

{{myVar === "two" ? "it's true" : "it's false"}}

Many in the community would prefer no limit with warnings about performance, see this comment for a well reasoned argument: https://jira.mongodb.org/browse/SERVER-431?focusedCommentId=22283&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-22283

My take, the lead developers are stubborn about this issue because they decided it was an important "feature" early on. They're not going to change it anytime soon because their feelings are hurt that anyone questioned it. Another example of personality and politics detracting from a product in open source communities but this is not really a crippling issue.

The above works,(having an original document with mixed pages of 11' and 16' wide). However auto rotate needs to be off otherwise landscape pages are saved with page white top and bottom, so dont work in full screen view.

Solution is to re open the new PDF in acrobat and crop the first image (carefully to avoid white border), then select page range i.e. all, this then applies to all pages. job done !

This is java answer.

df.select("id").collectAsList();

Is it possible to do it this way, as opposed to using something like Raphael or jQuery SVG?

Definitely.

If it is possible, what's the technique?

This annotated code snippet works:

<!DOCTYPE html>
<html>
    <head>
        <title>SVG Illustrator Test</title> 
    </head>
    <body>

        <object data="alpha.svg" type="image/svg+xml"
         id="alphasvg" width="100%" height="100%"></object>

        <script>
            var a = document.getElementById("alphasvg");

            // It's important to add an load event listener to the object,
            // as it will load the svg doc asynchronously
            a.addEventListener("load",function(){

                // get the inner DOM of alpha.svg
                var svgDoc = a.contentDocument;
                // get the inner element by id
                var delta = svgDoc.getElementById("delta");
                // add behaviour
                delta.addEventListener("mousedown",function(){
                        alert('hello world!')
                }, false);
            }, false);
        </script>
    </body>
</html>

Note that a limitation of this technique is that it is restricted by the same-origin policy, so alpha.svg must be hosted on the same domain as the .html file, otherwise the inner DOM of the object will be inaccessible.

Important thing to run this HTML, you need host HTML file to web server like IIS, Tomcat

Execute at Admin privilege using sudo in order to avoid permission denied (Unable to change file mode) error.

sudo chmod 777 <directory location>

The key is to keep the declarations of the variable in the header file and source file the same.

I use this trick

------sample.c------
#define sample_c
#include sample.h

(rest of sample .c)

------sample.h------
#ifdef sample_c
#define EXTERN
#else
#define EXTERN extern
#endif

EXTERN int x;

Sample.c is only compiled once and it defines the variables. Any file that includes sample.h is only given the "extern" of the variable; it does allocate space for that variable.

When you change the type of x, it will change for everybody. You won't need to remember to change it in the source file and the header file.

The pack method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame size explicitly by calling setSize or setBounds (which also sets the frame location). In general, using pack is preferable to calling setSize, since pack leaves the frame layout manager in charge of the frame size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.

From Java tutorial

You should also refer to Javadocs any time you need additional information on any Java API

If you want to update the app icon in the taskbar, then Update following in main.js (if using typescript then main.ts)

win.setIcon(path.join(__dirname, '/src/assets/logo-small.png'));

__dirname points to the root directory (same directory as package.json) of your application.

DOM stands for Document Object Model. It is the W3C(World Wide Web Consortium) Standard. It define standard for accessing and manipulating HTML and XML document and The elements of DOM is head,title,body tag etc. So the answer of your first statement is

Statement #1 You can add multiple classes to a single DOM element.

Explanation : "div class="cssclass1 cssclass2 cssclass3"

Here tag is element of DOM and i have applied multiple classes to DOM element.

Here is how to do it using TCP IP protocol :

// Printer IP Address and communication port
    string ipAddress = "10.3.14.42";
   int port = 9100;

// ZPL Command(s)
   string ZPLString =
    "^XA" +
    "^FO50,50" +
    "^A0N50,50" +
    "^FDHello, World!^FS" +
    "^XZ";

   try
   {
    // Open connection
    System.Net.Sockets.TcpClient client = new System.Net.Sockets.TcpClient();
    client.Connect(ipAddress, port);

    // Write ZPL String to connection
    System.IO.StreamWriter writer =
    new System.IO.StreamWriter(client.GetStream());
    writer.Write(ZPLString);
    writer.Flush();

    // Close Connection
    writer.Close();
    client.Close();
}
catch (Exception ex)
{
    // Catch Exception
}

If you receive the message about the unrecognized host key while doing git push/pull operations using ATLASSIAN SOURCETREE you do not have the ability to answer y/n and the push/pull operation will be aborted without caching the key. However going to SourceTree Tools->Options (General Tab) and changing the SSH Client under (under SSH Client Configuration) from PuTTY to OpenSSH will allow the key to be cached without changing anything else.

To change the default setting to display line numbers in vi/vim:

vi ~/.vimrc

then add the following line to the file:

set number

Either we can source ~/.vimrc or save and quit by :wq, now future vi/vim sessions will have numbering :)

If you are getting this error on GitLab CI like me: Just change from latest to 5.7 version ;)

# .gitlab-ci.yml

rspec:
  services:
    # - mysql:latest (I'm using latest version and it causes error)
    - mysql:5.7 #(then I've changed to this specific version and fix!)

This can be done using GroupBy and SelectMany in LINQ lamda expression

var groupByMax = list.GroupBy(x=>x.item1).SelectMany(y=>y.Where(z=>z.item2 == y.Max(i=>i.item2)));

Between execution of left != null and queue.add(left) another thread could have changed the value of left to null.

To work around this you have several options. Here are some:

1. Use a local variable with smart cast:

    val node = left
    if (node != null) {
        queue.add(node)
    }
   

2. Use a safe call such as one of the following:

    left?.let { node -> queue.add(node) }
    left?.let { queue.add(it) }
    left?.let(queue::add)
   

3. Use the Elvis operator with return to return early from the enclosing function:

    queue.add(left ?: return)
   

   Note that break and continue can be used similarly for checks within loops.

If you're looking to make the elements be 33.3% only on small devices and lower:

This is backwards from what Bootstrap is designed for, but you can do this:

<div class="row">
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
</div>

This will make each element 33.3% wide on small and extra small devices but 100% wide on medium and larger devices.

JSFiddle: http://jsfiddle.net/jdwire/sggt8/embedded/result/

If you're only looking to hide elements for smaller devices:

I think you're looking for the visible-xs and/or visible-sm classes. These will let you make certain elements only visible to small screen devices.

For example, if you want a element to only be visible to small and extra-small devices, do this:

<div class="visible-xs visible-sm">You're using a fairly small device.</div>

To show it only for larger screens, use this:

<div class="hidden-xs hidden-sm">You're probably not using a phone.</div>

Old Timer Favorite (it still works):

List<String> list;

for(int i = list.size() - 1; i >= 0; --i) 
{
        if(list.get(i).contains("bad"))
        {
                list.remove(i);
        }
}

Benefits:

1. It only iterates over the list once
2. No extra objects created, or other unneeded complexity
3. No problems with trying to use the index of a removed item, because... well, think about it!

You can use the getTime() method on a Date object to get the timestamp (in milliseconds) relative to January 1, 1970. If you convert your two dates into integer timestamps, you can then compare the difference by subtracting them. The result will be in milliseconds so you just divide by 1000 for seconds, then 60 for minutes, etc.

Try this it is working fine for me..

EditText.setInputType(0);
EditText.setFilters(new InputFilter[] {new InputFilter()
{
@Override
public CharSequence filter(CharSequence source, int start,
                            int end, Spanned dest, int dstart, int dend) 
{
return source.length() < 1 ? dest.subSequence(dstart, dend) : "";

}
}
});

Swift 5 : For evenly distributed spaces between cells with dynamic cell width to make the best of container space you may use the code snippet below by providing a minimumCellWidth value.

private func collectionViewLayout() -> UICollectionViewLayout {
    
    let layout = UICollectionViewFlowLayout()
    layout.sectionHeadersPinToVisibleBounds = true
    // Important: if direction is horizontal use minimumItemSpacing instead. 
    layout.scrollDirection = .vertical
    
    let itemHeight: CGFloat = 240
    let minCellWidth :CGFloat = 130.0
    let minItemSpacing: CGFloat = 10
    let containerWidth: CGFloat = self.view.bounds.width
    let maxCellCountPerRow: CGFloat =  floor((containerWidth - minItemSpacing) / (minCellWidth+minItemSpacing ))
    
    let itemWidth: CGFloat = floor( ((containerWidth - (2 * minItemSpacing) - (maxCellCountPerRow-1) * minItemSpacing) / maxCellCountPerRow  ) )
    // Calculate the remaining space after substracting calculating cellWidth (Divide by 2 because of left and right insets)
    let inset = max(minItemSpacing, floor( (containerWidth - (maxCellCountPerRow*itemWidth) - (maxCellCountPerRow-1)*minItemSpacing) / 2 ) )

    
    layout.itemSize = CGSize(width: itemWidth, height: itemHeight)
    layout.minimumInteritemSpacing = min(minItemSpacing,inset)
    layout.minimumLineSpacing = minItemSpacing
    layout.sectionInset = UIEdgeInsets(top: minItemSpacing, left: inset, bottom: minItemSpacing, right: inset)

    
    return layout
}

Because % is only defined for integer types. That's the modulus operator.

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

I can't believe no-one has answered the ops question!

The last set of brackets are used for passing in the parameters to the anonymous function. So, the following example creates a function, then runs it with the x=5 and y=8

(function(x,y){
    //code here
})(5,8)

This may seem not so useful, but it has its place. The most common one I have seen is

(function($){
    //code here
})(jQuery)

which allows for jQuery to be in compatible mode, but you can refer to it as "$" within the anonymous function.

Identifiers (including column names) that are not double-quoted are folded to lower case in PostgreSQL. Column names that were created with double-quotes and thereby retained upper-case letters (and/or other syntax violations) have to be double-quoted for the rest of their life:

"first_Name"

Values (string literals / constants) are enclosed in single quotes:

'xyz'

So, yes, PostgreSQL column names are case-sensitive (when double-quoted):

SELECT * FROM persons WHERE "first_Name" = 'xyz';

Read the manual on identifiers here.

My standing advice is to use legal, lower-case names exclusively so double-quoting is not needed.

I might be too late to answer this question, but wanted to share my input for the benefit of the community. For this example, let me call your matrix 'ANOVA', and I am assuming you're just trying to remove rows from this matrix with 0's only in the 5th column.

indx = []
for i in range(len(ANOVA)):
    if int(ANOVA[i,4]) == int(0):
        indx.append(i)

ANOVA = [x for x in ANOVA if not x in indx]

When you define varchar etc without a length, the default is 1.

When n is not specified in a data definition or variable declaration statement, the default length is 1. When n is not specified with the CAST function, the default length is 30.

So, if you expect 400 bytes in the @trackingItems1 column from stock, use nvarchar(400).

Otherwise, you are trying to fit >1 character into nvarchar(1) = fail

As a comment, this is bad use of table value function too because it is "multi statement". It can be written like this and it will run better

ALTER FUNCTION [dbo].[testing1](@price int)
RETURNS
AS
   SELECT ta.item, ta.warehouse, ta.price 
   FROM   stock ta
   WHERE  ta.price >= @price;

Of course, you could just use a normal SELECT statement..

Just to point out that there is an approach using functions from the tidyverse, which I find more readable than gsub:

a %>% stringr::str_remove(pattern = ".*_")

Use 10.0.2.2 for default AVD and 10.0.3.2 for Genymotion

you can determine the last element with this code :

for i,element in enumerate(list):
    if (i==len(list)-1):
        print("last element is" + element)

You can also create a new jsp file sayng that form is submited and in your main action file just write its file name

Eg. Your form is submited is in a file succes.jsp Then your action file will have

Request.sendRedirect("success.jsp")

Yes, you can try,

php_value error_log "/var/log/php_log" 

in .htaccess or you can have users use ini_set() in the beginning of their scripts if they want to have logging.

Another option would be to enable scripts to default to the php.ini in the folder with the script, then go to the user/host's root folder, then to the server's root, or something similar. This would allow hosts to add their own php.ini values and their own error_log locations.

Although it seems the previous solutions would work, if a single anomaly occurs in the document the output would go to pieces. Below is a bit safer.

sed -n '/KEY/{
N
s/\n/ /p
}' somefile.txt

Use Fail module.

1. Use ignore_errors with every task that you need to ignore in case of errors.
2. Set a flag (say, result = false) whenever there is a failure in any task execution
3. At the end of the playbook, check if flag is set, and depending on that, fail the execution

- fail: msg="The execution has failed because of errors."
  when: flag == "failed"

Update:

Use register to store the result of a task like you have shown in your example. Then, use a task like this:

- name: Set flag
  set_fact: flag = failed
  when: "'FAILED' in command_result.stderr"

Yes. You need to use the "Searched" form rather than the "Simple" form of the CASE expression

SELECT CASE
         WHEN c.Number IN ( '1121231', '31242323' ) THEN 1
         WHEN c.Number IN ( '234523', '2342423' ) THEN 2

I use XCOPY with the following parameters for copying .NET assemblies:

/D /Y /R /H 

/D:m-d-y - Copies files changed on or after the specified date. If no date is given, copies only those files whose source time is newer than the destination time.

/Y - Suppresses prompting to confirm you want to overwrite an existing destination file.

/R - Overwrites read-only files.

/H - Copies hidden and system files also.

I would recommend using the LINQ extension methods. You can easily do it with one line of code like so:

list2 = list2.Except(list1).ToList();

This is assuming of course the objects in list1 that you are removing from list2 are the same instance.

This is not due to input tags not having any content per-se, but that their content is outside the scope of CSS.

input elements are a special type called replaced elements, these do not support :pseudo selectors like :before and :after.

In CSS, a replaced element is an element whose representation is outside the scope of CSS. These are kind of external objects whose representation is independent of the CSS. Typical replaced elements are <img>, <object>, <video> or form elements like <textarea> and <input>. Some elements, like <audio> or <canvas> are replaced elements only in specific cases. Objects inserted using the CSS content properties are anonymous replaced elements.

Note that this is even referred to in the spec:

This specification does not fully define the interaction of :before and :after with replaced elements (such as IMG in HTML).

And more explicitly:

Replaced elements do not have ::before and ::after pseudo-elements

I would recommend setting the HR itself to be 0px high and use its border to be visible instead. I have noticed that when you zoom in and out (ctrl + mouse wheel) the thickness of HR itself changes, while when you set the border it always stays the same:

hr {
    height: 0px;
    border: none;
    border-top: 1px solid black;
}

bash and sh are two different shells. Basically bash is sh, with more features and better syntax. Most commands work the same, but they are different.Bash (bash) is one of many available (yet the most commonly used) Unix shells. Bash stands for "Bourne Again SHell",and is a replacement/improvement of the original Bourne shell (sh).

Shell scripting is scripting in any shell, whereas Bash scripting is scripting specifically for Bash. In practice, however, "shell script" and "bash script" are often used interchangeably, unless the shell in question is not Bash.

Having said that, you should realize /bin/sh on most systems will be a symbolic link and will not invoke sh. In Ubuntu /bin/sh used to link to bash, typical behavior on Linux distributions, but now has changed to linking to another shell called dash. I would use bash, as that is pretty much the standard (or at least most common, from my experience). In fact, problems arise when a bash script will use #!/bin/sh because the script-maker assumes the link is to bash when it doesn't have to be.

Short answer is that you don't 'decrypt' the password (because it's not encrypted - it's hashed).

The long answer is that you shouldn't send the user their password by email, or any other way. If the user has forgotten their password, you should send them a password reset email, and allow them to change their password on your website.

Laravel has most of this functionality built in (see the Laravel documentation - I'm not going to replicate it all here. Also available for versions 4.2 and 5.0 of Laravel).

For further reading, check out this 'blogoverflow' post: Why passwords should be hashed.

Use this:

$parameter = $_SERVER['QUERY_STRING'];
echo $parameter;

Or just use:

$parameter = $_GET['link'];
echo $parameter ;

Java supports Regular Expressions, but they're kind of cumbersome if you actually want to use them to extract matches. I think the easiest way to get at the string you want in your example is to just use the Regular Expression support in the String class's replaceAll method:

String x = "test string (67)".replaceAll(".*\\(|\\).*", "");
// x is now the String "67"

This simply deletes everything up-to-and-including the first (, and the same for the ) and everything thereafter. This just leaves the stuff between the parenthesis.

However, the result of this is still a String. If you want an integer result instead then you need to do another conversion:

int n = Integer.parseInt(x);
// n is now the integer 67

+= adds a number to a variable, changing the variable itself in the process (whereas + would not). Similar to this, there are the following that also modifies the variable:

• -=, subtracts a value from variable, setting the variable to the result
• *=, multiplies the variable and a value, making the outcome the variable
• /=, divides the variable by the value, making the outcome the variable
• %=, performs modulus on the variable, with the variable then being set to the result of it

There may be others. I am not a Python programmer.

this could do it:

perl -ne 'if(m/name="(.*?)"/){ print $1 . "\n"; }'

You can use :

$query->getSQL();

If you are using MySQL you can use Workbench to view running SQL statements. You can also use view the running query from mysql by using the following :

 SHOW FULL PROCESSLIST \G

E-mail addresses are very difficult to verify correctly with a mere regex. Here is a pretty scary regex that supposedly implements RFC822, chapter 6, the specification of valid e-mail addresses.

Not really an answer, but maybe related to what you're trying to accomplish.

I had a similar instance where I wanted to use .toFixed() where necessary, but I didn't want the padding when it wasn't. So I ended up using parseFloat in conjunction with toFixed.

toFixed without padding

parseFloat(n.toFixed(4));

Another option that does almost the same thing
This answer may help your decision

Number(n.toFixed(4));

toFixed will round/pad the number to a specific length, but also convert it to a string. Converting that back to a numeric type will not only make the number safer to use arithmetically, but also automatically drop any trailing 0's. For example:

var n = "1.234000";
    n = parseFloat(n);
 // n is 1.234 and in number form

Because even if you define a number with trailing zeros they're dropped.

var n = 1.23000;
 // n == 1.23;

Ok, so you've switched the column from Number to VARCHAR(5). Now you need to update the zipcode field to be left-padded. The SQL to do that would be:

UPDATE MyTable
SET ZipCode = LPAD( ZipCode, 5, '0' );

This will pad all values in the ZipCode column to 5 characters, adding '0's on the left.

Of course, now that you've got all of your old data fixed, you need to make sure that your any new data is also zero-padded. There are several schools of thought on the correct way to do that:

• Handle it in the application's business logic. Advantages: database-independent solution, doesn't involve learning more about the database. Disadvantages: needs to be handled everywhere that writes to the database, in all applications.

• Handle it with a stored procedure. Advantages: Stored procedures enforce business rules for all clients. Disadvantages: Stored procedures are more complicated than simple INSERT/UPDATE statements, and not as portable across databases. A bare INSERT/UPDATE can still insert non-zero-padded data.

• Handle it with a trigger. Advantages: Will work for Stored Procedures and bare INSERT/UPDATE statements. Disadvantages: Least portable solution. Slowest solution. Triggers can be hard to get right.

In this case, I would handle it at the application level (if at all), and not the database level. After all, not all countries use a 5-digit Zipcode (not even the US -- our zipcodes are actually Zip+4+2: nnnnn-nnnn-nn) and some allow letters as well as digits. Better NOT to try and force a data format and to accept the occasional data error, than to prevent someone from entering the correct value, even though it's format isn't quite what you expected.

My solution to this one, which I like because it is nicely general, is as follows:

/// <summary>
/// Automagically convert known interfaces to (specific) concrete classes on deserialisation
/// </summary>
public class WithMocksJsonConverter : JsonConverter
{
    /// <summary>
    /// The interfaces I know how to instantiate mapped to the classes with which I shall instantiate them, as a Dictionary.
    /// </summary>
    private readonly Dictionary<Type,Type> conversions = new Dictionary<Type,Type>() { 
        { typeof(IOne), typeof(MockOne) },
        { typeof(ITwo), typeof(MockTwo) },
        { typeof(IThree), typeof(MockThree) },
        { typeof(IFour), typeof(MockFour) }
    };

    /// <summary>
    /// Can I convert an object of this type?
    /// </summary>
    /// <param name="objectType">The type under consideration</param>
    /// <returns>True if I can convert the type under consideration, else false.</returns>
    public override bool CanConvert(Type objectType)
    {
        return conversions.Keys.Contains(objectType);
    }

    /// <summary>
    /// Attempt to read an object of the specified type from this reader.
    /// </summary>
    /// <param name="reader">The reader from which I read.</param>
    /// <param name="objectType">The type of object I'm trying to read, anticipated to be one I can convert.</param>
    /// <param name="existingValue">The existing value of the object being read.</param>
    /// <param name="serializer">The serializer invoking this request.</param>
    /// <returns>An object of the type into which I convert the specified objectType.</returns>
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        try
        {
            return serializer.Deserialize(reader, this.conversions[objectType]);
        }
        catch (Exception)
        {
            throw new NotSupportedException(string.Format("Type {0} unexpected.", objectType));
        }
    }

    /// <summary>
    /// Not yet implemented.
    /// </summary>
    /// <param name="writer">The writer to which I would write.</param>
    /// <param name="value">The value I am attempting to write.</param>
    /// <param name="serializer">the serializer invoking this request.</param>
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }
}

}

You could obviously and trivially convert it into an even more general converter by adding a constructor which took an argument of type Dictionary<Type,Type> with which to instantiate the conversions instance variable.

Using node I have a collection of stuff @stuff and access it like this:

- each stuff in stuffs
  p
    = stuff.sentence

When you do new Promise((resolve)... the type inferred was Promise<{}> because you should have used new Promise<number>((resolve).

It is interesting that this issue was only highlighted when the async keyword was added. I would recommend reporting this issue to the TS team on GitHub.

There are many ways you can get around this issue. All the following functions have the same behavior:

const whatever1 = () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever2 = async () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever3 = async () => {
    return await new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever4 = async () => {
    return Promise.resolve(4);
};

const whatever5 = async () => {
    return await Promise.resolve(4);
};

const whatever6 = async () => Promise.resolve(4);

const whatever7 = async () => await Promise.resolve(4);

In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>.

 X <- data.frame(Variable1=c(11,14,12,15),Variable2=c(2,3,1,4))
> X
  Variable1 Variable2
1        11         2
2        14         3
3        12         1
4        15         4
> X[X$Variable1!=11 & X$Variable1!=12, ]
  Variable1 Variable2
2        14         3
4        15         4
> X[ ! X$Variable1 %in% c(11,12), ]
  Variable1 Variable2
2        14         3
4        15         4

You can functionalize this however you like.

getimagesize() returns an array containing the image properties.

list($width, $height) = getimagesize("path/to/image.jpg");

to just get the width and height or

list($width, $height, $type, $attr)

to get some more information.

Marius's answer worked perfectly for me:

df.reset_index() sets the index as the first column, with the column label "index." You can now use the index as an axis for plotting, as described in his answer:

monthly_mean.reset_index().plot(x='index', y='A')

However, this does not change the original dataframe. The original dataframe will be unchanged unless it is set using df = df.reset_index().

example:

df.reset_index()
print(df)

This question has been hanging around for a while, but none of the fixes I could find worked for me (having the same issue with ipad), but I managed my own solution which should work for most people I imagine.

Here's my code:

html {
   background: url("../images/blahblah.jpg") repeat-y;
   min-width: 100%;
   background-size: contain;
}

Enjoy!

You cannot simply add a link using CSS. CSS is used for styling.

You can style your using CSS.

If you want to give a link dynamically to then I will advice you to use jQuery or Javascript.

You can accomplish that very easily using jQuery.

I have done a sample for you. You can refer that.

URL : http://jsfiddle.net/zyk9w/

$('#link').attr('href','http://www.google.com');

This single line will do the trick.

Here is another option for Angular (using own formatting function) - this one is for format:

YYYY-mm-dd hh:nn:ss

-you can adjust to your formats, just re-order the lines and change separators

dateAsYYYYMMDDHHNNSS(date): string {
  return date.getFullYear()
            + '-' + this.leftpad(date.getMonth() + 1, 2)
            + '-' + this.leftpad(date.getDate(), 2)
            + ' ' + this.leftpad(date.getHours(), 2)
            + ':' + this.leftpad(date.getMinutes(), 2)
            + ':' + this.leftpad(date.getSeconds(), 2);
}

leftpad(val, resultLength = 2, leftpadChar = '0'): string {
  return (String(leftpadChar).repeat(resultLength)
        + String(val)).slice(String(val).length);
}

For current time stamp use like this:

const curTime = this.dateAsYYYYMMDDHHNNSS(new Date());
console.log(curTime);

Will output e.g: 2018-12-31 23:00:01

Make your life easier by using CSS Selectors

I know I have come late to party but I have a nice suggestion for you.

Using BeautifulSoup is already been suggested I would rather prefer using CSS Selectors to scrape data inside HTML

import urllib2
from bs4 import BeautifulSoup

main_url = "http://www.example.com"

main_page_html  = tryAgain(main_url)
main_page_soup = BeautifulSoup(main_page_html)

# Scrape all TDs from TRs inside Table
for tr in main_page_soup.select("table.class_of_table"):
   for td in tr.select("td#id"):
       print(td.text)
       # For acnhors inside TD
       print(td.select("a")[0].text)
       # Value of Href attribute
       print(td.select("a")[0]["href"])

# This is method that scrape URL and if it doesnt get scraped, waits for 20 seconds and then tries again. (I use it because my internet connection sometimes get disconnects)
def tryAgain(passed_url):
    try:
        page  = requests.get(passed_url,headers = random.choice(header), timeout = timeout_time).text
        return page
    except Exception:
        while 1:
            print("Trying again the URL:")
            print(passed_url)
            try:
                page  = requests.get(passed_url,headers = random.choice(header), timeout = timeout_time).text
                print("-------------------------------------")
                print("---- URL was successfully scraped ---")
                print("-------------------------------------")
                return page
            except Exception:
                time.sleep(20)
                continue 

To convert any JSON to array, use the below code:

const usersJson: any[] = Array.of(res.json());

That is a very interesting question.

On the Lang.Next conference there was a very interesting discussion about this topic, in which authors of several programming languages participate (Scala, Dart, C#). There was not a clear consensus at the end, but from my point of view there is one message:

The ideal language for this "cloud age" should be object oriented (because that is how we understand and are able to model the world) and also embrace functional programming.

The code in "cloud age" is almost always distributed: running on several cores/machines (in the cloud center) or just the client/server separation. And it is also asynchronous. We do not block the code when waiting for WS response. The callbacks come in any time.

When using standard imperative programming languages, handling the asynchrony and the distribution really complicated. You have to always take care of the "current state" and when the callbacks come in, you have to decide what to do, in dependences of this state.

Functional programming helps to eliminate the "state" and is much better suited for this new situation.

So I would say: In cloud computing the code is distributed, state-less, asynchronous. Functional programming can help you with that. Object oriented is almost a must to be able to model the world.

I have wrote a blog post about it, if you are interested. I like C#, but actually I would say Scala, Clojure, F# might fit even better.

On the other hand C++ will always be there, and lately is being modernized and getting more attention.

Invoking any method on any null reference will always result in an exception. Test if the object is null first:

List<Object> test = null;
if (test != null && !test.isEmpty()) {
    // ...
}

Alternatively, write a method to encapsulate this logic:

public static <T> boolean IsNullOrEmpty(Collection<T> list) {
    return list == null || list.isEmpty();
}

Then you can do:

List<Object> test = null;
if (!IsNullOrEmpty(test)) {
    // ...
}

It has to do with how the public members of the base class are exposed from the derived class.

• public -> base class's public members will be public (usually the default)
• protected -> base class's public members will be protected
• private -> base class's public members will be private

As litb points out, public inheritance is traditional inheritance that you'll see in most programming languages. That is it models an "IS-A" relationship. Private inheritance, something AFAIK peculiar to C++, is an "IMPLEMENTED IN TERMS OF" relationship. That is you want to use the public interface in the derived class, but don't want the user of the derived class to have access to that interface. Many argue that in this case you should aggregate the base class, that is instead of having the base class as a private base, make in a member of derived in order to reuse base class's functionality.

The performance benefit is from not having to reopen the file once the #pragma once have been read. With guards, the compiler have to open the file (that can be costly in time) to get the information that it shouldn't include it's content again.

That is theory only because some compilers will automatically not open files that didn't have any read code in, for each compilation unit.

Anyway, it's not the case for all compilers, so ideally #pragma once have to be avoided for cross-platform code has it's not standard at all / have no standardized definition and effect. However, practically, it's really better than guards.

In the end, the better suggestion you can get to be sure to have the best speed from your compiler without having to check the behavior of each compiler in this case, is to use both pragma once and guards.

#ifndef NR_TEST_H
#define NR_TEST_H
#pragma once

#include "Thing.h"

namespace MyApp
{
 // ...
}

#endif

That way you get the best of both (cross-platform and help compilation speed).

As it's longer to type, I personally use a tool to help generate all that in a very wick way (Visual Assist X).

In my opinion, the simpler and most elegant way to add a delay in a loop is like this:

names = ['John', 'Ana', 'Mary'];

names.forEach((name, i) => {
 setTimeout(() => {
  console.log(name);
 }, i * 1000);  // one sec interval
});

Here's one aspect that could rule the difference:

If you change an element's style in JavaScript, you are affecting the inline style. If there's already a style there, you overwrite it permanently. But, if the style were defined in an external sheet or in a <style> tag, then setting the inline one to "" restores the style from that source.

I noticed one error in Dave Ward's answer (perhaps a recent change?): The query string paramaters are in request.query, not request.params. (See https://stackoverflow.com/a/6913287/166530 )

request.params by default is filled with the value of any "component matches" in routes, i.e.

app.get('/user/:id', function(request, response){
  response.send('user ' + request.params.id);
});

and, if you have configured express to use its bodyparser (app.use(express.bodyParser());) also with POST'ed formdata. (See How to retrieve POST query parameters? )

you can test if have exactly some values, by example:

for(MyBoolean b : MyBoolean.values()) {
    switch(b) {
    case TRUE:
        break;
    case FALSE:
        break;
    default:
        throw new IllegalArgumentException(b.toString());
}

for(String s : new String[]{"TRUE", "FALSE" }) {
    MyBoolean.valueOf(s);
}

If someone removes or adds a value, some of test fails.

Wow it is very simple. i'm blame to write this, why no one make it before?

$(function(){
    //Yes! use keydown 'cus some keys is fired only in this trigger,
    //such arrows keys
    $("body").keydown(function(e){
         //well you need keep on mind that your browser use some keys 
         //to call some function, so we'll prevent this
         e.preventDefault();

         //now we caught the key code, yabadabadoo!!
         var keyCode = e.keyCode || e.which;

         //your keyCode contains the key code, F1 to F12 
         //is among 112 and 123. Just it.
         console.log(keyCode);       
    });
});

How about something like this...

Dim rs As RecordSet
Set rs = Currentdb.OpenRecordSet("SELECT PictureLocation, ID FROM MyAccessTable;")

Do While Not rs.EOF
   Debug.Print rs("PictureLocation") & " - " & rs("ID")
   rs.MoveNext
Loop

In Main try changing the call to GetList to:

Task.Run(() => bs.GetList());

The command docker build --no-cache . solved our similar problem.

Our Dockerfile was:

RUN apt-get update
RUN apt-get -y install php5-fpm

But should have been:

RUN apt-get update && apt-get -y install php5-fpm

To prevent caching the update and install separately.

See: Best practices for writing Dockerfiles

For those new to Java and wondering why Jiri's answer doesn't work, make sure you do what he says and handle the exception or else it won't compile. Here's the bare minimum:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadFile {

    public static void main(String args[]) throws IOException {
        BufferedReader br = new BufferedReader(new FileReader("test.txt"));
        for (String line; (line = br.readLine()) != null;) {
            System.out.print(line);
        }
        br.close()
    }
}

I found that max_new_space_size is not an option in node 4.1.1 and max_old_space_size alone did not solve my problem. I am adding the following to my shebang and the combination of these seems to work:

#!/usr/bin/env node --max_old_space_size=4096 --optimize_for_size --max_executable_size=4096 --stack_size=4096

[EDIT]: 4096 === 4GB of memory, if your device is low on memory you may want to choose a smaller amount.

[UPDATE]: Also discovered this error while running grunt which previously was run like so:

./node_modules/.bin/grunt

After updating the command to the following it stopped having memory errors:

node --max_old_space_size=2048 ./node_modules/.bin/grunt 

To resolve this issue you have to do two things :

1. You will need to set a registry entry on the target computer so that the driver can maintain a connection to the instance of Internet Explorer it creates.

2. Change few settings of Internet Explorer browser on that machine (where you desire to run automation).

1 . Setting Registry Key / Entry :

• To set registry key or entry, you need to open "Registry Editor".

• To open "Registry Editor" press windows button key + r alphabet key which will open "Run Window" and then type "regedit" and press enter.

• Or Press Windows button key and enter "regedit" at start menu and press enter. Now depending upon your OS type whether 32/64 bit follow the corresponding steps.

Windows 32 bit : go to this location - "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl" and check for "FEATURE_BFCACHE" key.

Windows 64 bit : go to this location - HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl and check for "FEATURE_BFCACHE" key. Please note that the FEATURE_BFCACHE subkey may or may not be present, and should be created if it is not present.

Important: Inside this key, create a DWORD value named iexplore.exe with the value of 0.

2 . Change Settings of Internet Explorer Browser :

• Click on setting button and select "Internet options".

• On "Internet options" window go to "Security" tab

• Now select "Internet" option and unchecked the "Enable Protected Mode" check box and change the "Security level" to low.

• Now select "Local Intranet" Option and change the "Security level" to low.

• Now select "Trusted Sites" Option and change the "Security level" to low.

• Now click on "Apply" button , a warning pop up may appear click on "OK" button for warning and then on "OK" button on Internet Options window.

• After this restart the browser.

You can place your tables in a div and add style to your table "float: left"

<div>
  <table style="float: left">
    <tr>
      <td>..</td>
    </tr>
  </table>
  <table style="float: left">
    <tr>
      <td>..</td>
    </tr>
  </table>
</div>

or simply use css:

div>table {
  float: left
}

You can simply use setKeepScreenOn() from the View class.

Yes, #id selectors combined with a multiple selector (comma) is perfectly valid in both jQuery and CSS.

However, for your example, since <script> comes before the elements, you need a document.ready handler, so it waits until the elements are in the DOM to go looking for them, like this:

<script>
  $(function() {
    $("#segement1,#segement2,#segement3").hide()
  });
</script>

<div id="segement1"></div>
<div id="segement2"></div>
<div id="segement3"></div>

In my case, adding a dtype attribute changed dtype of the array to a smaller type(from float64 to uint8), decreasing array size enough to not throw MemoryError in Windows(64 bit).

from

mask = np.zeros(edges.shape)

to

mask = np.zeros(edges.shape,dtype='uint8')

For this is important to understand the difference between Merge and Rebase.

Rebases are how changes should pass from the top of hierarchy downwards and merges are how they flow back upwards.

Try the following:

color.gradient <- function(x, colors=c("red","yellow","green"), colsteps=100) {
  return( colorRampPalette(colors) (colsteps) [ findInterval(x, seq(min(x),max(x), length.out=colsteps)) ] )
}
x <- c((1:100)^2, (100:1)^2)
plot(x,col=color.gradient(x), pch=19,cex=2)

You can use the ipextract shell tools I made for this purpose. They are based on regexp and grep.

Usage:

$ ifconfig | ipextract6
fe80::1%lo0
::1
fe80::7ed1:c3ff:feec:dee1%en0

('my string'.match(/\s/g) || []).length;

If you want to extract the hours, minutes and seconds, try this:

String inputDate = "12:00:00";
String[] split = inputDate.split(":");
int hours = Integer.valueOf(split[0]);
int minutes = Integer.valueOf(split[1]);
int seconds = Integer.valueOf(split[2]);

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

Try restarting the mysql or starting it if it wasn't started already. Type this within terminal.

You'll need a PDF API for C#. iTextSharp is one possible API, though better ones might exist.

iTextSharp Example

You must install iTextSharp.dll as a reference. Download iTextsharp from SourceForge.net This is a complete working program using a console application.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using iTextSharp.text.pdf;
using iTextSharp.text.xml;
namespace GetPages_PDF
{
  class Program
{
    static void Main(string[] args)
      {
       // Right side of equation is location of YOUR pdf file
        string ppath = "C:\\aworking\\Hawkins.pdf";
        PdfReader pdfReader = new PdfReader(ppath);
        int numberOfPages = pdfReader.NumberOfPages;
        Console.WriteLine(numberOfPages);
        Console.ReadLine();
      }
   }
}

Query performance mainly depends on the number of records it needs to scan, indexes plays a high role in it and index data size is proportional to number of rows and number of indexes.

Queries with indexed field conditions along with full value would be returned in 1ms generally, but starts_with, IN, Between, obviously contains conditions might take more time with more records to scan.

Also you will face lot of maintenance issues with DDL, like ALTER, DROP will be slow and difficult with more live traffic even for adding a index or new columns.

Generally its advisable to cluster the Database into as many clusters as required (500GB would be a general benchmark, as said by others it depends on many factors and can vary based on use cases) that way it gives better isolation and gives independence to scale specific clusters (more suited in case of B2B)

I solved problem like yours by this commands:

git reset --hard HEAD^
git push -f <remote> <local branch>:<remote branch> 

I think your problem is that you send the broadcast before the other activity start ! so the other activity will not receive anything .

1. The best practice to test your code is to sendbroadcast from thread or from a service so the activity is opened and its registered the receiver and the background process sends a message.
2. start the ToastDisplay activity from the sender activity ( I didn't test that but it may work probably )

var selector = '.classname';
$(selector).on('click', function(){
    $(selector).removeClass('classname');
    $(this).addClass('classname');
});

In your example, the -D parts are not picked up:

hadoop jar Test_Parallel_for.jar Test_Parallel_for Matrix/test4.txt Result 3 \ -D mapred.map.tasks = 20 \ -D mapred.reduce.tasks =0

They should come after the classname part like this:

hadoop jar Test_Parallel_for.jar Test_Parallel_for -Dmapred.map.tasks=20 -Dmapred.reduce.tasks=0 Matrix/test4.txt Result 3

A space after -D is allowed though.

Also note that changing the number of mappers is probably a bad idea as other people have mentioned here.

You should be able to access the INSERTED table and retrieve ID or table's primary key. Something similar to this example ...

CREATE TRIGGER [dbo].[after_update] ON [dbo].[MYTABLE]
AFTER UPDATE AS 
BEGIN
    DECLARE @id AS INT
    SELECT @id = [IdColumnName]
    FROM INSERTED

    UPDATE MYTABLE 
    SET mytable.CHANGED_ON = GETDATE(),
    CHANGED_BY=USER_NAME(USER_ID())
    WHERE [IdColumnName] = @id

Here's a link on MSDN on the INSERTED and DELETED tables available when using triggers: http://msdn.microsoft.com/en-au/library/ms191300.aspx

Use localStorage to store the fact that you opened the page :

$(document).ready(function() {
    var yetVisited = localStorage['visited'];
    if (!yetVisited) {
        // open popup
        localStorage['visited'] = "yes";
    }
});

Here is what i did on ubuntu 18.04 LTS with Jenkins 2.176.2

I created .bash_aliases file and added there path, proxy variables and so on.

In beginning of .bashrc there was this defined.

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

So it's checking that if we are start non-interactive shell then we don't do nothing here.

bottom of the .bashrc there was include for .bash_aliases

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

so i moved .bash_aliases loading first at .bashrc just above non-interactive check.

This didn't work first but then i disconnected slave and re-connected it so it's loading variables again. You don't need to restart whole jenkins if you are modifying slave variables. just disconnect and re-connect.

I've spent half a day on this problem. It's best to import using SQL Server Import & Export data wizard. There is a setting in that wizard which solves this problem. Detailed screenshots here: https://www.mssqltips.com/sqlservertip/1316/strip-double-quotes-from-an-import-file-in-integration-services-ssis/ Thanks

give this a try,

insert into tableName (ImageColumn) 
SELECT BulkColumn 
FROM Openrowset( Bulk 'image..Path..here', Single_Blob) as img

Why are you writing the code for calculating the distance by yourself?

Not calling Close probably bypasses sending a bunch of Win32 messages which one would think are somewhat important though I couldn't specifically tell you why...

Close has the benefit of raising events (that can be cancelled) such that an outsider (to the form) could watch for FormClosing and FormClosed in order to react accordingly.

I'm not clear whether FormClosing and/or FormClosed are raised if you simply dispose the form but I'll leave that to you to experiment with.
