Nginx subdomain configuration

You could move the common parts to another configuration file and include from both server contexts. This should work:

server {
  listen 80;
  server_name server1.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

server {
  listen 80;
  server_name another-one.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled (normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org's configuration file is /etc/nginx/sites-enabled and it looks like this:

server {
  listen   80 default_server;
  listen   [2a01:4f8:120:3105::101:1]:80 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-80;
}

server {
  listen   443 default_server;
  listen   [2a01:4f8:120:3105::101:1]:443 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/ssl-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-443;
}

As an example here's the /etc/nginx/include.d/all-common file that's included from both server contexts:

index index.html index.htm index.php .dirindex.php;
try_files $uri $uri/ =404;

location ~ /\.ht {
  deny all;
}

location = /favicon.ico {
  log_not_found off;
  access_log off;
}

location ~ /(README|ChangeLog)$ {
  types { }
  default_type text/plain;
}

Initializing select with AngularJS and ng-repeat

OK. If you don't want to use the correct way ng-options, you can add ng-selected attribute with a condition check logic for the option directive to to make the pre-select work.

<select ng-model="filterCondition.operator">
    <option ng-selected="{{operator.value == filterCondition.operator}}"
            ng-repeat="operator in operators"
            value="{{operator.value}}">
      {{operator.displayName}}
    </option>
</select>

How to get JavaScript caller function line number? How to get JavaScript caller source URL?

Answers are simple. No and No (No).

By the time javascript is running the concept of source files/urls from which the come is gone.

There is also no way to determine a line number because again by the time of execution the notion of code "lines" is no longer meaningful in Javascript.

Specific implementations may provide API hooks to allow priviledged code access to such details for the purpose of debugging but these APIs are not exposed to ordinary standard Javascript code.

how to pass data in an hidden field from one jsp page to another?

The code from Alex works great. Just note that when you use request.getParameter you must use a request dispatcher

//Pass results back to the client
RequestDispatcher dispatcher =   getServletContext().getRequestDispatcher("TestPages/ServiceServlet.jsp");
dispatcher.forward(request, response);

Calculating distance between two points (Latitude, Longitude)

As you're using SQL 2008 or later, I'd recommend checking out the GEOGRAPHY data type. SQL has built in support for geospatial queries.

e.g. you'd have a column in your table of type GEOGRAPHY which would be populated with a geospatial representation of the coordinates (check out the MSDN reference linked above for examples). This datatype then exposes methods allowing you to perform a whole host of geospatial queries (e.g. finding the distance between 2 points)

input file appears to be a text format dump. Please use psql

The answer above didn't work for me, this worked:

psql db_development < postgres_db.dump

How to acces external json file objects in vue.js app

If your file looks like this:

[
    {
        "firstname": "toto",
        "lastname": "titi"
    },
    {
        "firstname": "toto2",
        "lastname": "titi2"
    },
]

You can do:

import json from './json/data.json';
// ....
json.forEach(x => { console.log(x.firstname, x.lastname); });

Delete column from SQLite table

In Python 3.8... Preserves primary key and column types.

Takes 3 inputs:

  1. a sqlite cursor: db_cur,
  2. table name: t and,
  3. list of columns to junk: columns_to_junk
def removeColumns(db_cur, t, columns_to_junk):

    # Obtain column information
    sql = "PRAGMA table_info(" + t + ")"
    record = query(db_cur, sql)

    # Initialize two strings: one for column names + column types and one just
    # for column names
    cols_w_types = "("
    cols = ""

    # Build the strings, filtering for the column to throw out
    for r in record:
        if r[1] not in columns_to_junk:
            if r[5] == 0:
                cols_w_types += r[1] + " " + r[2] + ","
            if r[5] == 1:
                cols_w_types += r[1] + " " + r[2] + " PRIMARY KEY,"
            cols += r[1] + ","

    # Cut potentially trailing commas
    if cols_w_types[-1] == ",":
        cols_w_types = cols_w_types[:-1]
    else:
        pass

    if cols[-1] == ",":
        cols = cols[:-1]
    else:
        pass

    # Execute SQL
    sql = "CREATE TEMPORARY TABLE xfer " + cols_w_types + ")"
    db_cur.execute(sql)
    sql = "INSERT INTO xfer SELECT " + cols + " FROM " + t
    db_cur.execute(sql)
    sql = "DROP TABLE " + t
    db_cur.execute(sql)
    sql = "CREATE TABLE " + t + cols_w_types + ")"
    db_cur.execute(sql)
    sql = "INSERT INTO " + t + " SELECT " + cols  + " FROM xfer"
    db_cur.execute(sql)

You'll find a reference to a query() function. Just a helper...

Takes two inputs:

  1. sqlite cursor db_cur and,
  2. the query string: query
def query(db_cur, query):

    r = db_cur.execute(query).fetchall()

    return r

Don't forget to include a "commit()"!

SQL Server: combining multiple rows into one row

I believe for databases which support listagg function, you can do:

select id, issue, customfield, parentkey, listagg(stingvalue, ',') within group (order by id)
from jira.customfieldvalue
where customfield = 12534 and issue = 19602
group by id, issue, customfield, parentkey

How to use HTTP.GET in AngularJS correctly? In specific, for an external API call?

First, your success() handler just returns the data, but that's not returned to the caller of getData() since it's already in a callback. $http is an asynchronous call that returns a $promise, so you have to register a callback for when the data is available.

I'd recommend looking up Promises and the $q library in AngularJS since they're the best way to pass around asynchronous calls between services.

For simplicity, here's your same code re-written with a function callback provided by the calling controller:

var myApp = angular.module('myApp',[]);

myApp.service('dataService', function($http) {
    delete $http.defaults.headers.common['X-Requested-With'];
    this.getData = function(callbackFunc) {
        $http({
            method: 'GET',
            url: 'https://www.example.com/api/v1/page',
            params: 'limit=10, sort_by=created:desc',
            headers: {'Authorization': 'Token token=xxxxYYYYZzzz'}
        }).success(function(data){
            // With the data succesfully returned, call our callback
            callbackFunc(data);
        }).error(function(){
            alert("error");
        });
     }
});

myApp.controller('AngularJSCtrl', function($scope, dataService) {
    $scope.data = null;
    dataService.getData(function(dataResponse) {
        $scope.data = dataResponse;
    });
});

Now, $http actually already returns a $promise, so this can be re-written:

var myApp = angular.module('myApp',[]);

myApp.service('dataService', function($http) {
    delete $http.defaults.headers.common['X-Requested-With'];
    this.getData = function() {
        // $http() returns a $promise that we can add handlers with .then()
        return $http({
            method: 'GET',
            url: 'https://www.example.com/api/v1/page',
            params: 'limit=10, sort_by=created:desc',
            headers: {'Authorization': 'Token token=xxxxYYYYZzzz'}
         });
     }
});

myApp.controller('AngularJSCtrl', function($scope, dataService) {
    $scope.data = null;
    dataService.getData().then(function(dataResponse) {
        $scope.data = dataResponse;
    });
});

Finally, there's better ways to configure the $http service to handle the headers for you using config() to setup the $httpProvider. Checkout the $http documentation for examples.

Cannot push to GitHub - keeps saying need merge

Is your branch name the same as the remote branch name?

If no, you should checkout a new branch with the same name as the remote branch and try push it again.

Assume the remote branch you want to push is [testing] and your local branch is named as [test].

If you`re not in test branch, first switch to it.

git checkout test

Then open a new branch and name it testing.

git checkout -b testing

Now, it`s time to push it:

git push [remote repo] testing

How to find sitemap.xml path on websites?

According to protocol documentation there are at least three options website designers can use to inform sitemap.xml location to search engines:

  • Informing each search engine of the location through their provided interface
  • Adding url to the robots.txt file
  • Submiting url to search engines through http

So, unless they have chosen to publish the sitemap location on their robots.txt file, you cannot really know where they have put their sitemap.xml files.

npm throws error without sudo

Problem: You do not have permission to write to the directories that npm uses to store global packages and commands.

Solution: Allow permission for npm.

Open a terminal:

command + spacebar then type 'terminal'

Enter this command:

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
  • Note: this will require your password.

This solution allows permission to ONLY the directories needed, keeping the other directories nice and safe.

Avoid duplicates in INSERT INTO SELECT query in SQL Server

Using ignore Duplicates on the unique index as suggested by IanC here was my solution for a similar issue, creating the index with the Option WITH IGNORE_DUP_KEY

In backward compatible syntax
, WITH IGNORE_DUP_KEY is equivalent to WITH IGNORE_DUP_KEY = ON.

Simplest way to download and unzip files in Node.js cross-platform?

Checkout adm-zip.

ADM-ZIP is a pure JavaScript implementation for zip data compression for NodeJS.

The library allows you to:

  • decompress zip files directly to disk or in-memory buffers
  • compress files and store them to disk in .zip format or in compressed buffers
  • update content of/add new/delete files from an existing .zip

MySQL - UPDATE query with LIMIT

When dealing with null, = does not match the null values. You can use IS NULL or IS NOT NULL

UPDATE `smartmeter_usage`.`users_reporting` 
SET panel_id = 3 WHERE panel_id IS NULL

LIMIT can be used with UPDATE but with the row count only

How to convert integers to characters in C?

Casting the integer to a char will do what you want.

char theChar=' ';
int theInt = 97;
theChar=(char) theInt;

cout<<theChar<<endl;

There is no difference between 'a' and 97 besides the way you interperet them.

Get user's non-truncated Active Directory groups from command line

A little stale post, but I figured what the heck. Does "whoami" meet your needs?

I just found out about it today (from the same Google search that brought me here, in fact). Windows has had a whoami tool since XP (part of an add on toolkit) and has been built-in since Vista.

whoami /groups

Lists all the AD groups for the currently logged-on user. I believe it does require you to be logged on AS that user, though, so this won't help if your use case requires the ability to run the command to look at another user.

Group names only:

whoami /groups /fo list |findstr /c:"Group Name:"

Boolean checking in the 'if' condition

The former. The latter merely adds verbosity.

android : Error converting byte to dex

After I upgraded to Android Studio 2.1, the next time I rebooted, I was asked to upgrade to JDK 1.8. After I upgraded to JDK 1.8, that's when my AS project had trouble compiling. I followed all of the suggestions in this page, but to no avail. Finally, I decided to check the version of JDK that my project was using, and to my surprise, it somehow was pointing to JDK 1.8!

Moral of the story: If compileSdkVersion<=23, double check that your project is using JDK1.7 as follows:

  • Right Mouse on top level module
  • Project STructure => JDK Location

PostgreSQL error: Fatal: role "username" does not exist

Follow These Steps and it Will Work For You :

  1. run msfconsole
  2. type db_console
  3. some information will be shown to you chose the information who tell you to make: db_connect user:pass@host:port.../database sorry I don't remember it but it's like this one then replace the user and the password and the host and the database with the information included in the database.yml in the emplacement: /usr/share/metasploit-framework/config
  4. you will see. rebuilding the model cache in the background.
  5. Type apt-get update && apt-get upgrade after the update restart the terminal and lunch msfconsole and it works you can check that by typing in msfconsole: msf>db_status you will see that it's connected.

Setting "checked" for a checkbox with jQuery

When you checked a checkbox like;

$('.className').attr('checked', 'checked')

it might not be enough. You should also call the function below;

$('.className').prop('checked', 'true')

Especially when you removed the checkbox checked attribute.

Split string with string as delimiter

I've found two older scripts that use an indefinite or even a specific string to split. As an approach, these are always helpful.

How to rename a pane in tmux?

You can adjust the pane title by setting the pane border in the tmux.conf for example like this:

###############
# pane border #
###############
set -g pane-border-status bottom
#colors for pane borders
setw -g pane-border-style fg=green,bg=black
setw -g pane-active-border-style fg=colour118,bg=black
setw -g automatic-rename off
setw -g pane-border-format ' #{pane_index} #{pane_title} : #{pane_current_path} '
# active pane normal, other shaded out?
setw -g window-style fg=colour28,bg=colour16
setw -g window-active-style fg=colour46,bg=colour16

Where pane_index, pane_title and pane_current_path are variables provided by tmux itself.

After reloading the config or starting a new tmux session, you can then set the title of the current pane like this:

tmux select-pane -T "fancy pane title";
#or
tmux select-pane -t paneIndexInteger -T "fancy pane title";

If all panes have some processes running, so you can't use the command line, you can also type the commands after pressing the prefix bind (C-b by default) and a colon (:) without having "tmux" in the front of the command:

select-pane -T "fancy pane title"
#or:
select-pane -t paneIndexInteger -T "fancy pane title"

How can I use Html.Action?

You should look at the documentation for the Action method; it's explained well. For your case, this should work:

@Html.Action("GetOptions", new { pk="00", rk="00" });

The controllerName parameter will default to the controller from which Html.Action is being invoked. So if you're trying to invoke an action from another controller, you'll have to specify the controller name like so:

@Html.Action("GetOptions", "ControllerName", new { pk="00", rk="00" });

jQuery Validation using the class instead of the name value

Another way you can do it, is using addClassRules. It's specific for classes, while the option using selector and .rules is more a generic way.

Before calling

$(form).validate()

Use like this:

jQuery.validator.addClassRules('myClassName', {
        required: true /*,
        other rules */
    });

Ref: http://docs.jquery.com/Plugins/Validation/Validator/addClassRules#namerules

I prefer this syntax for a case like this.

How can I get Docker Linux container information from within the container itself?

As an aside, if you have the pid of the container and want to get the docker id of that container, a good way is to use nsenter in combination with the sed magic above:

nsenter -n -m -t pid -- cat /proc/1/cgroup | grep -o -e "docker-.*.scope" | head -n 1 | sed "s/docker-\(.*\).scope/\\1/"

How do I get my solution in Visual Studio back online in TFS?

I searched for the solution online and found this solution but wasn't too keen on the registry change.

I found a better way: right-click on the solution name right at the top of the Solution Explorer and select the Go Online option. Clicking this allowed me to select the files that had been changed when I was offline and make the solution online again.

After finding the solution, I found the following msdn forum thread which confirmed the above.

Getting a directory name from a filename

In C++17 there exists a class std::filesystem::path using the method parent_path.

#include <iostream>
#include <filesystem>
namespace fs = std::filesystem;
int main()
{
    for(fs::path p : {"/var/tmp/example.txt", "/", "/var/tmp/."})
        std::cout << "The parent path of " << p
                  << " is " << p.parent_path() << '\n';
}

Possible output:

The parent path of "/var/tmp/example.txt" is "/var/tmp"
The parent path of "/" is ""
The parent path of "/var/tmp/." is "/var/tmp"

How do I search for files in Visual Studio Code?

You can also press F1 to open the Command Palette and then remove the > via Backspace. Now you can search for files, too.

How do you reindex an array in PHP but with indexes starting from 1?

I just found out you can also do a

array_splice($ar, 0, 0);

That does the re-indexing inplace, so you don't end up with a copy of the original array.

Regular expression to match URLs in Java

((http?|https|ftp|file)://)?((W|w){3}.)?[a-zA-Z0-9]+\.[a-zA-Z]+

It sorts out theses entries correctly

Are HTTP headers case-sensitive?

The RFC for HTTP (as cited above) dictates that the headers are case-insensitive, however you will find that with certain browsers (I'm looking at you, IE) that capitalizing each of the words tends to be best:

Location: http://stackoverflow.com

Content-Type: text/plain

vs

location: http://stackoverflow.com

content-type: text/plain

This isn't "HTTP" standard, but just another one of the browser quirks, we as developers, have to think about.

Run a Java Application as a Service on Linux

I wrote another simple wrapper here:

#!/bin/sh
SERVICE_NAME=MyService

PID_PATH_NAME=/tmp/MyService-pid
case $1 in
    start)
        echo "Starting $SERVICE_NAME ..."
        if [ ! -f $PID_PATH_NAME ]; then
            nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
            echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is already running ..."
        fi
    ;;
    stop)
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME);
            echo "$SERVICE_NAME stoping ..."
            kill $PID;
            echo "$SERVICE_NAME stopped ..."
            rm $PID_PATH_NAME
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;
    restart)
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME);
            echo "$SERVICE_NAME stopping ...";
            kill $PID;
            echo "$SERVICE_NAME stopped ...";
            rm $PID_PATH_NAME
            echo "$SERVICE_NAME starting ..."
            nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
            echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;

You can follow a full tutorial for init.d here and for systemd (ubuntu 16+) here

If you need the output log replace the 2

nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &

lines for

nohup java -jar $PATH_TO_JAR >> myService.out 2>&1&

How to pass parameter to click event in Jquery

Better Approach:

<script type="text/javascript">
    $('#btn').click(function() {
      var id = $(this).attr('id');
      alert(id);
    });
</script>

<input id="btn" type="button" value="click" />

But, if you REALLY need to do the click handler inline, this will work:

<script type="text/javascript">
    function display(el) {
        var id = $(el).attr('id');
        alert(id);
    }
</script>

<input id="btn" type="button" value="click" OnClick="display(this);" />

Get latitude and longitude based on location name with Google Autocomplete API

I hope this can help someone in the future.

You can use the Google Geocoding API, as said before, I had to do some work with this recently, I hope this helps:

<!DOCTYPE html>
<html>
    <head>
        <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
        <script type="text/javascript">
        function initialize() {
        var address = (document.getElementById('my-address'));
        var autocomplete = new google.maps.places.Autocomplete(address);
        autocomplete.setTypes(['geocode']);
        google.maps.event.addListener(autocomplete, 'place_changed', function() {
            var place = autocomplete.getPlace();
            if (!place.geometry) {
                return;
            }

        var address = '';
        if (place.address_components) {
            address = [
                (place.address_components[0] && place.address_components[0].short_name || ''),
                (place.address_components[1] && place.address_components[1].short_name || ''),
                (place.address_components[2] && place.address_components[2].short_name || '')
                ].join(' ');
        }
      });
}
function codeAddress() {
    geocoder = new google.maps.Geocoder();
    var address = document.getElementById("my-address").value;
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {

      alert("Latitude: "+results[0].geometry.location.lat());
      alert("Longitude: "+results[0].geometry.location.lng());
      } 

      else {
        alert("Geocode was not successful for the following reason: " + status);
      }
    });
  }
google.maps.event.addDomListener(window, 'load', initialize);

        </script>
    </head>
    <body>
        <input type="text" id="my-address">
        <button id="getCords" onClick="codeAddress();">getLat&Long</button>
    </body>
</html>

Now this has also an autocomlpete function which you can see in the code, it fetches the address from the input and gets auto completed by the API while typing.

Once you have your address hit the button and you get your results via alert as required. Please also note this uses the latest API and it loads the 'places' library (when calling the API uses the 'libraries' parameter).

Hope this helps, and read the documentation for more information, cheers.

Detect when an HTML5 video finishes

Have a look at this Everything You Need to Know About HTML5 Video and Audio post at the Opera Dev site under the "I want to roll my own controls" section.

This is the pertinent section:

<video src="video.ogv">
     video not supported
</video>

then you can use:

<script>
    var video = document.getElementsByTagName('video')[0];

    video.onended = function(e) {
      /*Do things here!*/
    };
</script>

onended is a HTML5 standard event on all media elements, see the HTML5 media element (video/audio) events documentation.

iOS: how to perform a HTTP POST request?

EDIT: ASIHTTPRequest has been abandoned by the developer. It's still really good IMO, but you should probably look elsewhere now.

I'd highly recommend using the ASIHTTPRequest library if you are handling HTTPS. Even without https it provides a really nice wrapper for stuff like this and whilst it's not hard to do yourself over plain http, I just think the library is nice and a great way to get started.

The HTTPS complications are far from trivial in various scenarios, and if you want to be robust in handling all the variations, you'll find the ASI library a real help.

What does the fpermissive flag do?

The -fpermissive flag causes the compiler to report some things that are actually errors (but are permitted by some compilers) as warnings, to permit code to compile even if it doesn't conform to the language rules. You really should fix the underlying problem. Post the smallest, compilable code sample that demonstrates the problem.

-fpermissive
Downgrade some diagnostics about nonconformant code from errors to warnings. Thus, using -fpermissive will allow some nonconforming code to compile.

jQuery - find child with a specific class

$(this).find(".bgHeaderH2").html();

or

$(this).find(".bgHeaderH2").text();

Strip first and last character from C string

The most efficient way:

//Note destroys the original string by removing it's last char
// Do not pass in a string literal.
char * getAllButFirstAndLast(char *input)
{
  int len = strlen(input); 
  if(len > 0)
    input++;//Go past the first char
  if(len > 1)
    input[len - 2] = '\0';//Replace the last char with a null termination
  return input;
}


//...
//Call it like so
char str[512];
strcpy(str, "hello world");
char *pMod = getAllButFirstAndLast(str);

The safest way:

void getAllButFirstAndLast(const char *input, char *output)
{
  int len = strlen(input);
  if(len > 0)
    strcpy(output, ++input);
  if(len > 1)
    output[len - 2] = '\0';
}


//...
//Call it like so
char mod[512];
getAllButFirstAndLast("hello world", mod);

The second way is less efficient but it is safer because you can pass in string literals into input. You could also use strdup for the second way if you didn't want to implement it yourself.

Converting Milliseconds to Minutes and Seconds?

I would suggest using TimeUnit. You can use it like this:

long minutes = TimeUnit.MILLISECONDS.toMinutes(millis);
long seconds = TimeUnit.MILLISECONDS.toSeconds(millis);

Can I fade in a background image (CSS: background-image) with jQuery?

I know i'm late, but I found a way using jquery which works on every browser(i tested it on chrome, firefox and Ie 9)and th fore-ground elements are always displayed instead of css3 transition property.

create 2 absolute wrapper and using z-index.

First set the elements that have to be in the fore-ground with the highest z-index property value, and the other elemets(all included in the body, so: body{}) with a lower z-index property value than the fore-ground elements'one , at least of 2 number lower.

HTML part:

         <div class="wrapper" id="wrapper1"></div>
         <div class="wrapper" id="wrapper2"></div>

css part:

        .fore-groundElements{              //select all fore-ground elements
                  z-index:0;               //>=0
        }
       .wrapper{
                  background-size: cover;
                  width:100%;
                  height:100%;
                  background-size: 100% 100%;
                  position:absolute;
         }

        #wrapper1{
               z-index:-1; 
        }


        #wrapper2{
                 z-index:-2;
         }
         body{

              height:100%;
              width:100%;
              margin:0px;   
              display:cover;
              z-index:-3                          //<=-3
         }

than the javascript/jquery one:

i needed to change the background image every three second so i used a set timeout.

this is the code:

  $(document).ready(main);

  var main = function(){

             var imgPath=[imagesPath1,..,...];                 // the array in which store the image paths

             var newWrapper;                     // the wrapper to display 
             var currentWrapper;                 //the current displayed wrapper which has to be faded
             var l=2;                             // the next image index  to be displayed, it is set to 2 because the first two position of the array(first two images) start already setted up
             var imgNumber= imgPath.length;        //to know when the images are over and restart the carousel
             var currentImg;                       //the next image path to be displayed


             $('#wrapper1').css("background-image", 'url'+imgPath[0]);         //pre set the first wrapper background images
             $('#wrapper2').css("background-image", 'url'+imgPath[1]);          //pre set the first wrapper background images   

             setInterval(myfunction,3000);                //refresh the background image every three seconds

             function myfunction(){
                    if(l===imgNumber-1){               //restart the carousel if every single image has already been displayed                  
                         l=0;
                     };

             if(l%2==0||l%2==2){                    //set the wrapper that will be displaied after the fadeOut callback function
                  currentWrapper='#wrapper1';         
                  newWrapper='#wrapper2';
             }else{
                  currentWrapper='#wrapper2';
                  newWrapper='#wrapper1';
             };
             currentImg=imgPath[l];
            $(currentWrapper).fadeOut(1000,function(){               //fade out the current wrapper, so now the back-ground wrapper is fully displayed
                  $(newWrapper).css("z-index", "-1");                //move the shown wrapper in the fore-ground
                  $(currentWrapper).css("z-index","-2");             //move the hidden wrapper in the back ground
                  $(currentWrapper).css("background-image",'url'+currentImg);                   // sets up the next image that is now shown in the actually hidden background wrapper
                  $(currentWrapper).show();          //shows the background wrapper, which is not visible yet, and it will be shown the next time the setInterval event will be triggered
                  l++;                         //set the next image index that will be set the next time the setInterval event will be triggered 
             });


         };                   //end of myFunction
  }                          //end of main

How to split() a delimited string to a List<String>

List<string> stringList = line.Split(',').ToList(); 

z-index not working with position absolute

Old question but this answer might help someone.

If you are trying to display the contents of the container outside of the boundaries of the container, make sure that it doesn't have overflow:hidden, otherwise anything outside of it will be cut off.

Where do I find the definition of size_t?

size_t is the unsigned integer type of the result of the sizeof operator (ISO C99 Section 7.17.)

The sizeof operator yields the size (in bytes) of its operand, which may be an expression or the parenthesized name of a type. The size is determined from the type of the operand. The result is an integer. The value of the result is implementation-de?ned, and its type (an unsigned integer type) is size_t (ISO C99 Section 6.5.3.4.)

SQLite: How do I save the result of a query as a CSV file?

Good answers from gdw2 and d5e5. To make it a little simpler here are the recommendations pulled together in a single series of commands:

sqlite> select * from tbl1;
sqlite> .output stdout

How to make sure docker's time syncs with that of the host?

The source for this answer is the comment to the answer at: Will docker container auto sync time with the host machine?

After looking at the answer, I realized that there is no way a clock drift will occur on the docker container. Docker uses the same clock as the host and the docker cannot change it. It means that doing an ntpdate inside the docker does not work.

The correct thing to do is to update the host time using ntpdate

As far as syncing timezones is concerned, -v /etc/localtime:/etc/localtime:ro works.

Difference between getAttribute() and getParameter()

-getParameter() :

<html>
<body>
<form name="testForm" method="post" action="testJSP.jsp">
<input type="text" name="testParam" value="ClientParam">
<input type="submit">
</form>
</body>
</html>

    <html>
    <body>
    <%
    String sValue = request.getParameter("testParam");
    %>
    <%= sValue %>
    </body>
    </html>

request.getParameter("testParam") will get the value from the posted form of the input box named "testParam" which is "Client param". It will then print it out, so you should see "Client Param" on the screen. So request.getParameter() will retrieve a value that the client has submitted. You will get the value on the server side.

-getAttribute() : request.getAttribute(), this is all done server side. YOU add the attribute to the request and YOU submit the request to another resource, the client does not know about this. So all the code handling this would typically be in servlets.getAttribute always return object.

How to draw interactive Polyline on route google maps v2 android

You can use this method to draw polyline on googleMap

// Draw polyline on map
public void drawPolyLineOnMap(List<LatLng> list) {
    PolylineOptions polyOptions = new PolylineOptions();
    polyOptions.color(Color.RED);
    polyOptions.width(5);
    polyOptions.addAll(list);

    googleMap.clear();
    googleMap.addPolyline(polyOptions);

    LatLngBounds.Builder builder = new LatLngBounds.Builder();
    for (LatLng latLng : list) {
        builder.include(latLng);
    }

    final LatLngBounds bounds = builder.build();

    //BOUND_PADDING is an int to specify padding of bound.. try 100.
    CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, BOUND_PADDING);
    googleMap.animateCamera(cu);
}

You need to add this line in your gradle in case you haven't.

compile 'com.google.android.gms:play-services-maps:8.4.0'

Regex not operator

Not quite, although generally you can usually use some workaround on one of the forms

  • [^abc], which is character by character not a or b or c,
  • or negative lookahead: a(?!b), which is a not followed by b
  • or negative lookbehind: (?<!a)b, which is b not preceeded by a

Parse (split) a string in C++ using string delimiter (standard C++)

You can also use regex for this:

std::vector<std::string> split(const std::string str, const std::string regex_str)
{
    std::regex regexz(regex_str);
    std::vector<std::string> list(std::sregex_token_iterator(str.begin(), str.end(), regexz, -1),
                                  std::sregex_token_iterator());
    return list;
}

which is equivalent to :

std::vector<std::string> split(const std::string str, const std::string regex_str)
{
    std::sregex_token_iterator token_iter(str.begin(), str.end(), regexz, -1);
    std::sregex_token_iterator end;
    std::vector<std::string> list;
    while (token_iter != end)
    {
        list.emplace_back(*token_iter++);
    }
    return list;
}

and use it like this :

#include <iostream>
#include <string>
#include <regex>

std::vector<std::string> split(const std::string str, const std::string regex_str)
{   // a yet more concise form!
    return { std::sregex_token_iterator(str.begin(), str.end(), std::regex(regex_str), -1), std::sregex_token_iterator() };
}

int main()
{
    std::string input_str = "lets split this";
    std::string regex_str = " "; 
    auto tokens = split(input_str, regex_str);
    for (auto& item: tokens)
    {
        std::cout<<item <<std::endl;
    }
}

play with it online! http://cpp.sh/9sumb

you can simply use substrings, characters, etc like normal, or use actual regular expressions to do the splitting.
its also concise and C++11!

How do I see all foreign keys to a table or column?

For a Table:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>';

For a Column:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>' AND
  REFERENCED_COLUMN_NAME = '<column>';

Basically, we changed REFERENCED_TABLE_NAME with REFERENCED_COLUMN_NAME in the where clause.

Technically what is the main difference between Oracle JDK and OpenJDK?

Technical differences are a consequence of the goal of each one (OpenJDK is meant to be the reference implementation, open to the community, while Oracle is meant to be a commercial one)

They both have "almost" the same code of the classes in the Java API; but the code for the virtual machine itself is actually different, and when it comes to libraries, OpenJDK tends to use open libraries while Oracle tends to use closed ones; for instance, the font library.

How to list all tags along with the full message in git?

How can I fill out a Python string with spaces?

You can do this with str.ljust(width[, fillchar]):

Return the string left justified in a string of length width. Padding is done using the specified fillchar (default is a space). The original string is returned if width is less than len(s).

>>> 'hi'.ljust(10)
'hi        '

How to use PHP's password_hash to hash and verify passwords

Yes you understood it correctly, the function password_hash() will generate a salt on its own, and includes it in the resulting hash-value. Storing the salt in the database is absolutely correct, it does its job even if known.

// Hash a new password for storing in the database.
// The function automatically generates a cryptographically safe salt.
$hashToStoreInDb = password_hash($_POST['password'], PASSWORD_DEFAULT);

// Check if the hash of the entered login password, matches the stored hash.
// The salt and the cost factor will be extracted from $existingHashFromDb.
$isPasswordCorrect = password_verify($_POST['password'], $existingHashFromDb);

The second salt you mentioned (the one stored in a file), is actually a pepper or a server side key. If you add it before hashing (like the salt), then you add a pepper. There is a better way though, you could first calculate the hash, and afterwards encrypt (two-way) the hash with a server-side key. This gives you the possibility to change the key when necessary.

In contrast to the salt, this key should be kept secret. People often mix it up and try to hide the salt, but it is better to let the salt do its job and add the secret with a key.

Blockquote Adding libxml2 in Xcode 4.3.x

Adding libxml2 is a big, fat, finicky pain in the ass. If you're going to do it do it before you get too far in building your project.

Here's how.

Target settings

Click on your target (not your project) and select "Build Phases". Click on the reveal triangle titled "Link Binary With Libraries". Click on the "+" to add a library. Scroll to the bottom of the list and select "libxml2.dylib". That adds the libxml2 library 2 your project… but wait.

Project settings

Now you have to tell your project where to look for it three more times.

Select the "Build Settings tab". Scroll down to the "Linking" section. Under your project's columns double click on the "Other Linker Flags" row. Click the "+" and add "-lxml2" to the list.

Still more.

In the same tab, scroll down to the "Search Paths" section. Under your project's column in the "Framework Search Paths" row add "/usr/lib/libxml2.dylib".

In the "Header Search Paths" AND the "User Header Search Paths" row add "$(SDKROOT)/usr/include/libxml2". In those last two cases make sure that path is entered in Debug AND Release.

Then. Under the "Product" Menu select "Clean".

This is working and for Xcode5 too! Thank you!

ES6 export default with multiple functions referring to each other

The export default {...} construction is just a shortcut for something like this:

const funcs = {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { foo(); bar() }
}

export default funcs

It must become obvious now that there are no foo, bar or baz functions in the module's scope. But there is an object named funcs (though in reality it has no name) that contains these functions as its properties and which will become the module's default export.

So, to fix your code, re-write it without using the shortcut and refer to foo and bar as properties of funcs:

const funcs = {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { funcs.foo(); funcs.bar() } // here is the fix
}

export default funcs

Another option is to use this keyword to refer to funcs object without having to declare it explicitly, as @pawel has pointed out.

Yet another option (and the one which I generally prefer) is to declare these functions in the module scope. This allows to refer to them directly:

function foo() { console.log('foo') }
function bar() { console.log('bar') }
function baz() { foo(); bar() }

export default {foo, bar, baz}

And if you want the convenience of default export and ability to import items individually, you can also export all functions individually:

// util.js

export function foo() { console.log('foo') }
export function bar() { console.log('bar') }
export function baz() { foo(); bar() }

export default {foo, bar, baz}

// a.js, using default export

import util from './util'
util.foo()

// b.js, using named exports

import {bar} from './util'
bar()

Or, as @loganfsmyth suggested, you can do without default export and just use import * as util from './util' to get all named exports in one object.

document.getElementById vs jQuery $()

No.

Calling document.getElementById('id') will return a raw DOM object.

Calling $('#id') will return a jQuery object that wraps the DOM object and provides jQuery methods.

Thus, you can only call jQuery methods like css() or animate() on the $() call.

You can also write $(document.getElementById('id')), which will return a jQuery object and is equivalent to $('#id').

You can get the underlying DOM object from a jQuery object by writing $('#id')[0].

How to add onload event to a div element

As all said, you cannot use onLoad event on a DIV instead but it before body tag.

but in case you have one footer file and include it in many pages. it's better to check first if the div you want is on that page displayed, so the code doesn't executed in the pages that doesn't contain that DIV to make it load faster and save some time for your application.

so you will need to give that DIV an ID and do:

var myElem = document.getElementById('myElementId');
if (myElem !== null){ put your code here}

Best Python IDE on Linux

I haven't played around with it much but eclipse/pydev feels nice.

Vertical alignment of text and icon in button

Just wrap the button label in an extra span and add class="align-middle" to both (the icon and the label). This will center your icon with text vertical.

<button id="edit-listing-form-house_Continue" 
    class="btn btn-large btn-primary"
    style=""
    value=""
    name="Continue"
    type="submit">
<span class="align-middle">Continue</span>
<i class="icon-ok align-middle" style="font-size:40px;"></i>

Is it possible to reference one CSS rule within another?

No, you cannot reference one rule-set from another.

You can, however, reuse selectors on multiple rule-sets within a stylesheet and use multiple selectors on a single rule-set (by separating them with a comma).

.opacity, .someDiv {
    filter:alpha(opacity=60);
    -moz-opacity:0.6;
    -khtml-opacity: 0.6;
    opacity: 0.6; 
}
.radius, .someDiv {
    border-top-left-radius: 15px;
    border-top-right-radius: 5px;
    -moz-border-radius-topleft: 10px;
    -moz-border-radius-topright: 10px;    
}

You can also apply multiple classes to a single HTML element (the class attribute takes a space separated list).

<div class="opacity radius">

Either of those approaches should solve your problem.

It would probably help if you used class names that described why an element should be styled instead of how it should be styled. Leave the how in the stylesheet.

How to do a scatter plot with empty circles in Python?

Here's another way: this adds a circle to the current axes, plot or image or whatever :

from matplotlib.patches import Circle  # $matplotlib/patches.py

def circle( xy, radius, color="lightsteelblue", facecolor="none", alpha=1, ax=None ):
    """ add a circle to ax= or current axes
    """
        # from .../pylab_examples/ellipse_demo.py
    e = Circle( xy=xy, radius=radius )
    if ax is None:
        ax = pl.gca()  # ax = subplot( 1,1,1 )
    ax.add_artist(e)
    e.set_clip_box(ax.bbox)
    e.set_edgecolor( color )
    e.set_facecolor( facecolor )  # "none" not None
    e.set_alpha( alpha )

alt text

(The circles in the picture get squashed to ellipses because imshow aspect="auto" ).

Understanding repr( ) function in Python

>>> x = 'foo'
>>> x
'foo'

So the name x is attached to 'foo' string. When you call for example repr(x) the interpreter puts 'foo' instead of x and then calls repr('foo').

>>> repr(x)
"'foo'"
>>> x.__repr__()
"'foo'"

repr actually calls a magic method __repr__ of x, which gives the string containing the representation of the value 'foo' assigned to x. So it returns 'foo' inside the string "" resulting in "'foo'". The idea of repr is to give a string which contains a series of symbols which we can type in the interpreter and get the same value which was sent as an argument to repr.

>>> eval("'foo'")
'foo'

When we call eval("'foo'"), it's the same as we type 'foo' in the interpreter. It's as we directly type the contents of the outer string "" in the interpreter.

>>> eval('foo')

Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    eval('foo')
  File "<string>", line 1, in <module>
NameError: name 'foo' is not defined

If we call eval('foo'), it's the same as we type foo in the interpreter. But there is no foo variable available and an exception is raised.

>>> str(x)
'foo'
>>> x.__str__()
'foo'
>>> 

str is just the string representation of the object (remember, x variable refers to 'foo'), so this function returns string.

>>> str(5)
'5'

String representation of integer 5 is '5'.

>>> str('foo')
'foo'

And string representation of string 'foo' is the same string 'foo'.

How to search by key=>value in a multidimensional array in PHP

And another version that returns the key value from the array element in which the value is found (no recursion, optimized for speed):

// if the array is 
$arr['apples'] = array('id' => 1);
$arr['oranges'] = array('id' => 2);

//then 
print_r(search_array($arr, 'id', 2);
// returns Array ( [oranges] => Array ( [id] => 2 ) ) 
// instead of Array ( [0] => Array ( [id] => 2 ) )

// search array for specific key = value
function search_array($array, $key, $value) {
  $return = array();   
  foreach ($array as $k=>$subarray){  
    if (isset($subarray[$key]) && $subarray[$key] == $value) {
      $return[$k] = $subarray;
      return $return;
    } 
  }
}

How to get GET (query string) variables in Express.js on Node.js?

If you are using ES6 and Express, try this destructuring approach:

const {id, since, fields, anotherField} = request.query;

In context:

const express = require('express');
const app = express();

app.get('/', function(req, res){
   const {id, since, fields, anotherField} = req.query;
});

app.listen(3000);

You can use default values with destructuring too:

_x000D_
_x000D_
// sample request for testing_x000D_
const req = {_x000D_
  query: {_x000D_
    id: '123',_x000D_
    fields: ['a', 'b', 'c']_x000D_
  }_x000D_
}_x000D_
_x000D_
const {_x000D_
  id,_x000D_
  since = new Date().toString(),_x000D_
  fields = ['x'],_x000D_
  anotherField = 'default'_x000D_
} = req.query;_x000D_
_x000D_
console.log(id, since, fields, anotherField)
_x000D_
_x000D_
_x000D_

Change default global installation directory for node.js modules in Windows?

(git bash) npm config --global set prefix </path/you/want/to/use>/npm

(cmd/git-cmd) npm config --global set prefix <drive:\path\you\want\to\use>\npm

You may also consider the npm-cache location right next to it. (as would be in a normal nodejs installation on windows)

(git bash) npm config --global set cache </path/you/want/to/use>/npm-cache

(cmd/git-cmd) npm config --global set cache <drive:\path\you\want\to\use>\npm-cache

Import CSV to SQLite

I had exactly same problem (on OS X Maverics 10.9.1 with SQLite3 3.7.13, but I don't think SQLite is related to the cause). I tried to import csv data saved from MS Excel 2011, which btw. uses ';' as columns separator. I found out that csv file from Excel still uses newline character from Mac OS 9 times, changing it to unix newline solved the problem. AFAIR BBEdit has a command for this, as well as Sublime Text 2.

Why is using onClick() in HTML a bad practice?

Two more reasons not to use inline handlers:

They can require tedious quote escaping issues

Given an arbitrary string, if you want to be able to construct an inline handler that calls a function with that string, for the general solution, you'll have to escape the attribute delimiters (with the associated HTML entity), and you'll have to escape the delimiter used for the string inside the attribute, like the following:

_x000D_
_x000D_
const str = prompt('What string to display on click?', 'foo\'"bar');
const escapedStr = str
  // since the attribute value is going to be using " delimiters,
  // replace "s with their corresponding HTML entity:
  .replace(/"/g, '&quot;')
  // since the string literal inside the attribute is going to delimited with 's,
  // escape 's:
  .replace(/'/g, "\\'");
  
document.body.insertAdjacentHTML(
  'beforeend',
  '<button onclick="alert(\'' + escapedStr + '\')">click</button>'
);
_x000D_
_x000D_
_x000D_

That's incredibly ugly. From the above example, if you didn't replace the 's, a SyntaxError would result, because alert('foo'"bar') is not valid syntax. If you didn't replace the "s, then the browser would interpret it as an end to the onclick attribute (delimited with "s above), which would also be incorrect.

If one habitually uses inline handlers, one would have to make sure to remember do something similar to the above (and do it right) every time, which is tedious and hard to understand at a glance. Better to avoid inline handlers entirely so that the arbitrary string can be used in a simple closure:

_x000D_
_x000D_
const str = prompt('What string to display on click?', 'foo\'"bar');
const button = document.body.appendChild(document.createElement('button'));
button.textContent = 'click';
button.onclick = () => alert(str);
_x000D_
_x000D_
_x000D_

Isn't that so much nicer?


The scope chain of an inline handler is extremely peculiar

What do you think the following code will log?

_x000D_
_x000D_
let disabled = true;
_x000D_
<form>
  <button onclick="console.log(disabled);">click</button>
</form>
_x000D_
_x000D_
_x000D_

Try it, run the snippet. It's probably not what you were expecting. Why does it produce what it does? Because inline handlers run inside with blocks. The above code is inside three with blocks: one for the document, one for the <form>, and one for the <button>:

_x000D_
_x000D_
let disabled = true;
_x000D_
<form>
  <button onclick="console.log(disabled);">click</button>
</form>
_x000D_
_x000D_
_x000D_

enter image description here

Since disabled is a property of the button, referencing disabled inside the inline handler refers to the button's property, not the outer disabled variable. This is quite counter-intuitive. with has many problems: it can be the source of confusing bugs and significantly slows down code. It isn't even permitted at all in strict mode. But with inline handlers, you're forced to run the code through withs - and not just through one with, but through multiple nested withs. It's crazy.

with should never be used in code. Because inline handlers implicitly require with along with all its confusing behavior, inline handlers should be avoided as well.

JavaScript closures vs. anonymous functions

According to the closure definition:

A "closure" is an expression (typically a function) that can have free variables together with an environment that binds those variables (that "closes" the expression).

You are using closure if you define a function which use a variable which is defined outside of the function. (we call the variable a free variable).
They all use closure(even in the 1st example).

How to copy multiple files in one layer using a Dockerfile?

It might be worth mentioning that you can also create a .dockerignore file, to exclude the files that you don't want to copy:

https://docs.docker.com/engine/reference/builder/#dockerignore-file

Before the docker CLI sends the context to the docker daemon, it looks for a file named .dockerignore in the root directory of the context. If this file exists, the CLI modifies the context to exclude files and directories that match patterns in it. This helps to avoid unnecessarily sending large or sensitive files and directories to the daemon and potentially adding them to images using ADD or COPY.

Java 8: How do I work with exception throwing methods in streams?

You might want to do one of the following:

  • propagate checked exception,
  • wrap it and propagate unchecked exception, or
  • catch the exception and stop propagation.

Several libraries let you do that easily. Example below is written using my NoException library.

// Propagate checked exception
as.forEach(Exceptions.sneak().consumer(A::foo));

// Wrap and propagate unchecked exception
as.forEach(Exceptions.wrap().consumer(A::foo));
as.forEach(Exceptions.wrap(MyUncheckedException::new).consumer(A::foo));

Measuring text height to be drawn on Canvas ( Android )

You must use Rect.width() and Rect.Height() which returned from getTextBounds() instead. That works for me.

How can I get the current page's full URL on a Windows/IIS server?

Everyone forgot http_build_url?

http_build_url($_SERVER['REQUEST_URI']);

When no parameters are passed to http_build_url it will automatically assume the current URL. I would expect REQUEST_URI to be included as well, though it seems to be required in order to include the GET parameters.

The above example will return full URL.

How can I call the 'base implementation' of an overridden virtual method?

I konow it's history question now. But for other googlers: you could write something like this. But this requires change in base class what makes it useless with external libraries.

class A
{
  void protoX() { Console.WriteLine("x"); }
  virtual void X() { protoX(); }
}

class B : A
{
  override void X() { Console.WriteLine("y"); }
}

class Program
{
  static void Main()
  {
    A b = new B();
    // Call A.X somehow, not B.X...
    b.protoX();

Insert json file into mongodb

the following two ways work well:

C:\>mongodb\bin\mongoimport --jsonArray -d test -c docs --file example2.json
C:\>mongodb\bin\mongoimport --jsonArray -d test -c docs < example2.json

if the collections are under a specific user, you can use -u -p --authenticationDatabase

Setting up MySQL and importing dump within Dockerfile

The latest version of the official mysql docker image allows you to import data on startup. Here is my docker-compose.yml

data:
  build: docker/data/.
mysql:
  image: mysql
  ports:
    - "3307:3306"
  environment:
    MYSQL_ROOT_PASSWORD: 1234
  volumes:
    - ./docker/data:/docker-entrypoint-initdb.d
  volumes_from:
    - data

Here, I have my data-dump.sql under docker/data which is relative to the folder the docker-compose is running from. I am mounting that sql file into this directory /docker-entrypoint-initdb.d on the container.

If you are interested to see how this works, have a look at their docker-entrypoint.sh in GitHub. They have added this block to allow importing data

    echo
    for f in /docker-entrypoint-initdb.d/*; do
        case "$f" in
            *.sh)  echo "$0: running $f"; . "$f" ;;
            *.sql) echo "$0: running $f"; "${mysql[@]}" < "$f" && echo ;;
            *)     echo "$0: ignoring $f" ;;
        esac
        echo
    done

An additional note, if you want the data to be persisted even after the mysql container is stopped and removed, you need to have a separate data container as you see in the docker-compose.yml. The contents of the data container Dockerfile are very simple.

FROM n3ziniuka5/ubuntu-oracle-jdk:14.04-JDK8

VOLUME /var/lib/mysql

CMD ["true"]

The data container doesn't even have to be in start state for persistence.

How to center form in bootstrap 3

The total columns in a row has to add up to 12. So you can do col-md-4 col-md-offset-4. So your breaking up your columns into 3 groups of 4 columns each. Right now you have a 4 column form with an offset by 6 so you are only getting 2 columns to the right side of your form. You can also do col-md-8 col-md-offset-2 which would give you a 8 column form with 2 columns each of space left and right or col-md-6 col-md-offset-3 (6 column form with 3 columns space on each side), etc.

Cannot invoke an expression whose type lacks a call signature

TypeScript supports structural typing (also called duck typing), meaning that types are compatible when they share the same members. Your problem is that Apple and Pear don't share all their members, which means that they are not compatible. They are however compatible to another type that has only the isDecayed: boolean member. Because of structural typing, you don' need to inherit Apple and Pear from such an interface.

There are different ways to assign such a compatible type:

Assign type during variable declaration

This statement is implicitly typed to Apple[] | Pear[]:

const fruits = fruitBasket[key];

You can simply use a compatible type explicitly in in your variable declaration:

const fruits: { isDecayed: boolean }[] = fruitBasket[key];

For additional reusability, you can also define the type first and then use it in your declaration (note that the Apple and Pear interfaces don't need to be changed):

type Fruit = { isDecayed: boolean };
const fruits: Fruit[] = fruitBasket[key];

Cast to compatible type for the operation

The problem with the given solution is that it changes the type of the fruits variable. This might not be what you want. To avoid this, you can narrow the array down to a compatible type before the operation and then set the type back to the same type as fruits:

const fruits: fruitBasket[key];
const freshFruits = (fruits as { isDecayed: boolean }[]).filter(fruit => !fruit.isDecayed) as typeof fruits;

Or with the reusable Fruit type:

type Fruit = { isDecayed: boolean };
const fruits: fruitBasket[key];
const freshFruits = (fruits as Fruit[]).filter(fruit => !fruit.isDecayed) as typeof fruits;

The advantage of this solution is that both, fruits and freshFruits will be of type Apple[] | Pear[].

Missing Microsoft RDLC Report Designer in Visual Studio

Open Control Panel > Programs > Programs and Features

  • Select the entry for your version of Microsoft Visual Studio 2015. In our case, it was Microsoft Visual Studio Enterprise 2015.

  • Click the "Change" button on the top bar above the program list. After the splash screen, a window will open.

  • Press the "Modify" button.

  • Select Windows and Web Development > Microsoft SQL Server Data Tools, and check the box next to it.

  • Press the "Update" button on the lower-right hand side of the window.

Once the installation is complete, open your version of Visual Studio. After the new .dll files are loaded, Reporting functionality should be reimplemented, and you should be able to access all related forms, controls, and objects.

How to keep onItemSelected from firing off on a newly instantiated Spinner?

Unfortunately it seems that the two most commonly suggested solutions to this issue, namely counting callback occurrences and posting a Runnable to set the callback at a later time can both fail when for example accessibility options are enabled. Here's a helper class that works around these issues. Further explenation is in the comment block.

import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.Spinner;
import android.widget.SpinnerAdapter;

/**
 * Spinner Helper class that works around some common issues 
 * with the stock Android Spinner
 * 
 * A Spinner will normally call it's OnItemSelectedListener
 * when you use setSelection(...) in your initialization code. 
 * This is usually unwanted behavior, and a common work-around 
 * is to use spinner.post(...) with a Runnable to assign the 
 * OnItemSelectedListener after layout.
 * 
 * If you do not call setSelection(...) manually, the callback
 * may be called with the first item in the adapter you have 
 * set. The common work-around for that is to count callbacks.
 * 
 * While these workarounds usually *seem* to work, the callback
 * may still be called repeatedly for other reasons while the 
 * selection hasn't actually changed. This will happen for 
 * example, if the user has accessibility options enabled - 
 * which is more common than you might think as several apps 
 * use this for different purposes, like detecting which 
 * notifications are active.
 * 
 * Ideally, your OnItemSelectedListener callback should be
 * coded defensively so that no problem would occur even
 * if the callback was called repeatedly with the same values
 * without any user interaction, so no workarounds are needed.
 * 
 * This class does that for you. It keeps track of the values
 * you have set with the setSelection(...) methods, and 
 * proxies the OnItemSelectedListener callback so your callback
 * only gets called if the selected item's position differs 
 * from the one you have set by code, or the first item if you
 * did not set it.
 * 
 * This also means that if the user actually clicks the item
 * that was previously selected by code (or the first item
 * if you didn't set a selection by code), the callback will 
 * not fire.
 * 
 * To implement, replace current occurrences of:
 * 
 *     Spinner spinner = 
 *         (Spinner)findViewById(R.id.xxx);
 *     
 * with:
 * 
 *     SpinnerHelper spinner = 
 *         new SpinnerHelper(findViewById(R.id.xxx))
 *         
 * SpinnerHelper proxies the (my) most used calls to Spinner
 * but not all of them. Should a method not be available, use: 
 * 
 *      spinner.getSpinner().someMethod(...)
 *
 * Or just add the proxy method yourself :)
 * 
 * (Quickly) Tested on devices from 2.3.6 through 4.2.2

How to pass parameter to a promise function

PHP - Extracting a property from an array of objects

The solution depends on the PHP version you are using. At least there are 2 solutions:

First (Newer PHP versions)

As @JosepAlsina said before the best and also shortest solution is to use array_column as following:

$catIds = array_column($objects, 'id');

Notice: For iterating an array containing \stdClasses as used in the question it is only possible with PHP versions >= 7.0. But when using an array containing arrays you can do the same since PHP >= 5.5.

Second (Older PHP versions)

@Greg said in older PHP versions it is possible to do following:

$catIds = array_map(create_function('$o', 'return $o->id;'), $objects);

But beware: In newer PHP versions >= 5.3.0 it is better to use Closures, like followed:

$catIds = array_map(function($o) { return $o->id; }, $objects);


The difference

First solution creates a new function and puts it into your RAM. The garbage collector does not delete the already created and already called function instance out of memory for some reason. And that regardless of the fact, that the created function instance can never be called again, because we have no pointer for it. And the next time when this code is called, the same function will be created again. This behavior slowly fills your memory...

Both examples with memory output to compare them:

BAD

while (true)
{
    $objects = array_map(create_function('$o', 'return $o->id;'), $objects);

    echo memory_get_usage() . "\n";

    sleep(1);
}

// the output
4235616
4236600
4237560
4238520
...

GOOD

while (true)
{
    $objects = array_map(function($o) { return $o->id; }, $objects);

    echo memory_get_usage() . "\n";

    sleep(1);
}

// the output
4235136
4235168
4235168
4235168
...

SQL statement to select all rows from previous day

It's seems the obvious answer was missing. To get all data from a table (Ttable) where the column (DatetimeColumn) is a datetime with a timestamp the following query can be used:

SELECT * FROM Ttable
WHERE DATEDIFF(day,Ttable.DatetimeColumn ,GETDATE()) = 1 -- yesterday

This can easily be changed to today, last month, last year, etc.

How to programmatically disable page scrolling with jQuery

This may or may not work for your purposes, but you can extend jScrollPane to fire other functionality before it does its scrolling. I've only just tested this a little bit, but I can confirm that you can jump in and prevent the scrolling entirely. All I did was:

  • Download the demo zip: http://github.com/vitch/jScrollPane/archives/master
  • Open the "Events" demo (events.html)
  • Edit it to use the non-minified script source: <script type="text/javascript" src="script/jquery.jscrollpane.js"></script>
  • Within jquery.jscrollpane.js, insert a "return;" at line 666 (auspicious line number! but in case your version differs slightly, this is the first line of the positionDragY(destY, animate) function

Fire up events.html, and you'll see a normally scrolling box which due to your coding intervention won't scroll.

You can control the entire browser's scrollbars this way (see fullpage_scroll.html).

So, presumably the next step is to add a call to some other function that goes off and does your anchoring magic, then decides whether to continue with the scroll or not. You've also got API calls to set scrollTop and scrollLeft.

If you want more help, post where you get up to!

Hope this has helped.

Change the bullet color of list

I would recommend you to use background-image instead of default list.

.listStyle {
    list-style: none;
    background: url(image_path.jpg) no-repeat left center;
    padding-left: 30px;
    width: 20px;
    height: 20px;
}

Or, if you don't want to use background-image as bullet, there is an option to do it with pseudo element:

.liststyle{
    list-style: none;
    margin: 0;
    padding: 0;
}
.liststyle:before {
    content: "• ";
    color: red; /* or whatever color you prefer */
    font-size: 20px;/* or whatever the bullet size you prefer */
}

POST Content-Length exceeds the limit

8388608 bytes is 8M, the default limit in PHP. Those changes to php.ini should indeed solve the problem (make sure your restart your Apache server after making them).

Memory limit shouldn't need to be changed here.

Convert char* to string C++

std::string str(buffer, buffer + length);

Or, if the string already exists:

str.assign(buffer, buffer + length);

Edit: I'm still not completely sure I understand the question. But if it's something like what JoshG is suggesting, that you want up to length characters, or until a null terminator, whichever comes first, then you can use this:

std::string str(buffer, std::find(buffer, buffer + length, '\0'));

Should have subtitle controller already set Mediaplayer error Android

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

In ASP.NET, when should I use Session.Clear() rather than Session.Abandon()?

Session.Abandon destroys the session as stated above so you should use this when logging someone out. I think a good use of Session.Clear would be for a shopping basket on an ecommerce website. That way the basket gets cleared without logging out the user.

How to get HttpRequestMessage data

From this answer:

[HttpPost]
public void Confirmation(HttpRequestMessage request)
{
    var content = request.Content;
    string jsonContent = content.ReadAsStringAsync().Result;
}

Note: As seen in the comments, this code could cause a deadlock and should not be used. See this blog post for more detail.

Get model's fields in Django

If you need this for your admin site, there is also the ModelAdmin.get_fields method (docs), which returns a list of field name strings.

For example:

class MyModelAdmin(admin.ModelAdmin):
    # extending change_view, just as an example
    def change_view(self, request, object_id=None, form_url='', extra_context=None):
        # get the model field names
        field_names = self.get_fields(request)
        # use the field names

        'user' : {
          'username': username,
          'address': email,
          'password': password
       }
    };

    return http.post(
      url, 
      body: json.encode(body),
      headers: {
        "Content-Type": "application/json"
      },
      encoding: Encoding.getByName("utf-8")
    );
  }

boto3 client NoRegionError: You must specify a region error only sometimes

For those using CloudFormation template. You can set AWS_DEFAULT_REGION environment variable using UserData and AWS::Region. For example,

MyInstance1:
    Type: AWS::EC2::Instance                
    Properties:                           
        ImageId: ami-04b9e92b5572fa0d1 #ubuntu
        InstanceType: t2.micro
        UserData: 
            Fn::Base64: !Sub |
                    #!/bin/bash -x

                    echo "export AWS_DEFAULT_REGION=${AWS::Region}" >> /etc/profile

How can I perform a short delay in C# without using sleep?

You can probably use timers : http://msdn.microsoft.com/en-us/library/system.timers.timer.aspx

Timers can provide you a precision up to 1 millisecond. Depending on the tick interval an event will be generated. Do your stuff inside the tick event.

Get random integer in range (x, y]?

Just add one to the result. That turns [0, 10) into (0,10] (for integers). [0, 10) is just a more confusing way to say [0, 9], and (0,10] is [1,10] (for integers).

What is the easiest way to disable/enable buttons and links (jQuery + Bootstrap)

Suppose you have these buttons on page like :

<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit"value="Enable All" onclick="change()"/>

The js code:

function change(){

How to add multiple files to Git at the same time

If you want to add multiple files in a given folder you can split them using {,}. This is awesome for not repeating long paths, e.g.

git add long/path/{file1,file2,...,filen}

Beware not to put spaces between the ,.

How can I replace a regex substring match in Javascript?

I would get the part before and after what you want to replace and put them either side.

Like:

var str   = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;

var matches = str.match(regex);

var result = matches[1] + "1" + matches[2];

// With ES6:
var result = `${matches[1]}1${matches[2]}`;

How to initialize a list with constructor?

How to open a second activity on click of button in android app

Button btn = (Button) findViewById(R.id.button1);

btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent myIntent = new Intent(MainActivity.this, MainActivity2.class);
        MainActivity.this.startActivity(myIntent);       
    }  
});

The answer for the complete noob from a complete noob: MainActivity is the name of the first activity. MainActivity2 is the name of the second activity. button1 is the I.D of the button in xml for MainActivity Activity.

Jquery, set value of td in a table?

From:

it could be:

.html()

In an HTML document, .html() can be used to get the contents of any element.

.text()

Unlike the .html() method, .text() can be used in both XML and HTML documents. The result of the .text() method is a string containing the combined text of all matched elements.

.val()

The .val() method is primarily used to get the values of form elements such as input, select and textarea. When called on an empty collection, it returns undefined.

Finding the indices of matching elements in list in Python

if you're doing a lot of this kind of thing you should consider using numpy.

In [56]: import random, numpy

In [57]: lst = numpy.array([random.uniform(0, 5) for _ in range(1000)]) # example list

In [58]: a, b = 1, 3

In [59]: numpy.flatnonzero((lst > a) & (lst < b))[:10]
Out[59]: array([ 0, 12, 13, 15, 18, 19, 23, 24, 26, 29])

In response to Seanny123's question, I used this timing code:

import numpy, timeit, random

a, b = 1, 3

lst = numpy.array([random.uniform(0, 5) for _ in range(1000)])

def numpy_way():
    numpy.flatnonzero((lst > 1) & (lst < 3))[:10]

def list_comprehension():
    [e for e in lst if 1 < e < 3][:10]

print timeit.timeit(numpy_way)
print timeit.timeit(list_comprehension)

The numpy version is over 60 times faster.

Efficient thresholding filter of an array with numpy

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py
0:00:00.028000
0:00:02.461000

Java 8: merge lists with stream API

I think flatMap() is what you're looking for.

For example:

 List<AClass> allTheObjects = map.values()
         .stream()
         .flatMap(listContainer -> listContainer.lst.stream())
         .collect(Collectors.toList());

Comments in Android Layout xml

XML comments start with <!-- and end with -->.

How to turn off INFO logging in Spark?

This below code snippet for scala users :

Option 1 :

Below snippet you can add at the file level

import org.apache.log4j.{Level, Logger}
Logger.getLogger("org").setLevel(Level.WARN)

Option 2 :

Note : which will be applicable for all the application which is using spark session.

import org.apache.spark.sql.SparkSession

  private[this] implicit val spark = SparkSession.builder().master("local[*]").getOrCreate()

spark.sparkContext.setLogLevel("WARN")

Option 3 :

Note : This configuration should be added to your log4j.properties.. (could be like /etc/spark/conf/log4j.properties (where the spark installation is there) or your project folder level log4j.properties) since you are changing at module level. This will be applicable for all the application.

log4j.rootCategory=ERROR, console

IMHO, Option 1 is wise way since it can be switched off at file level.

How to control size of list-style-type disc in CSS?

try to use diffrent font-size for li and a

.farParentDiv ul li {
   list-style-type: disc;
   font-size:20px;
}

.farParentDiv ul li a {
   font-size:10px;
}

this saved me from using images

TypeError: got multiple values for argument

This happens when a keyword argument is specified that overwrites a positional argument. For example, let's imagine a function that draws a colored box. The function selects the color to be used and delegates the drawing of the box to another function, relaying all extra arguments.

def color_box(color, *args, **kwargs):
    painter.select_color(color)
    painter.draw_box(*args, **kwargs)

Then the call

color_box("blellow", color="green", height=20, width=30)

will fail because two values are assigned to color: "blellow" as positional and "green" as keyword. (painter.draw_box is supposed to accept the height and width arguments).

This is easy to see in the example, but of course if one mixes up the arguments at call, it may not be easy to debug:

# misplaced height and width
color_box(20, 30, color="green")

Here, color is assigned 20, then args=[30] and color is again assigned "green".

Android: how to create Switch case from this?

You can do this:

@Override
protected Dialog onCreateDialog(int id) {
    String messageDialog;
    String valueOK;
    String valueCancel;
    String titleDialog;
    switch (id) {

    case id:
        titleDialog = itemTitle;
        messageDialog = itemDescription
        valueOK = "OK";            
        return new AlertDialog.Builder(HomeView.this).setTitle(titleDialog).setPositiveButton(valueOK, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                Log.d(this.getClass().getName(), "AlertItem");
            }
        }).setMessage(messageDialog).create(); 

and then call to

showDialog(numbreOfItem);

Adding attributes to an XML node

You can use the Class XmlAttribute.

attr.Value = "Tushar";

node.Attributes.Append(attr);

React - uncaught TypeError: Cannot read property 'setState' of undefined

This error can be resolved by various methods-

  • If you are using ES5 syntax, then as per React js Documentation you have to use bind method.

    Something like this for the above example:

    this.delta = this.delta.bind(this)

  • If you are using ES6 syntax,then you need not use bind method,you can do it with something like this:

    delta=()=>{ this.setState({ count : this.state.count++ }); }

Laravel-5 how to populate select box from database with id value and name value

Laravel provides a Query Builder with lists() function

In your case, you can replace your code

$items = Items::all(['id', 'name']);

with

$items = Items::lists('name', 'id');

Also, you can chain it with other Query Builder as well.

$items = Items::where('active', true)->orderBy('name')->lists('name', 'id');

source: http://laravel.com/docs/5.0/queries#selects


Update for Laravel 5.2

Thank you very much @jarry. As you mentioned, the function for Laravel 5.2 should be

$items = Items::pluck('name', 'id');

or

$items = Items::where('active', true)->orderBy('name')->pluck('name', 'id');

Docker-Compose persistent data MySQL

The data container is a superfluous workaround. Data-volumes would do the trick for you. Alter your docker-compose.yml to:

version: '2'
services:
  mysql:
    container_name: flask_mysql
    restart: always
    image: mysql:latest
    environment:
      MYSQL_ROOT_PASSWORD: 'test_pass' # TODO: Change this
      MYSQL_USER: 'test'
      MYSQL_PASS: 'pass'
    volumes:
      - my-datavolume:/var/lib/mysql
volumes:
  my-datavolume:

Docker will create the volume for you in the /var/lib/docker/volumes folder. This volume persist as long as you are not typing docker-compose down -v

How to Create a circular progressbar in Android which rotates on it?

Good news is that now material design library supports determinate circular progress bars too:

SQL How to Select the most recent date item

Assuming your RDBMS know window functions and CTE and USER_ID is the patient's id:

WITH TT AS (
    SELECT *, ROW_NUMBER() OVER(PARTITION BY USER_ID ORDER BY DOCUMENT_DATE DESC) AS N
    FROM test_table
)
SELECT *
FROM TT
WHERE N = 1;

I assumed you wanted to sort by DOCUMENT_DATE, you can easily change that if wanted. If your RDBMS doesn't know window functions, you'll have to do a join :

SELECT *
FROM test_table T1
INNER JOIN (SELECT USER_ID, MAX(DOCUMENT_DATE) AS maxDate
            FROM test_table
            GROUP BY USER_ID) T2
    ON T1.USER_ID = T2.USER_ID
        AND T1.DOCUMENT_DATE = T2.maxDate;

It would be good to tell us what your RDBMS is though. And this query selects the most recent date for every patient, you can add a condition for a given patient.

Compute a confidence interval from sample data

Starting Python 3.8, the standard library provides the NormalDist object as part of the statistics module:

from statistics import NormalDist

def confidence_interval(data, confidence=0.95):
  dist = NormalDist.from_samples(data)
  z = NormalDist().inv_cdf((1 + confidence) / 2.)
  h = dist.stdev * z / ((len(data) - 1) ** .5)
  return dist.mean - h, dist.mean + h

This:

  • Creates a NormalDist object from the data sample (NormalDist.from_samples(data), which gives us access to the sample's mean and standard deviation via NormalDist.mean and NormalDist.stdev.

  • Compute the Z-score based on the standard normal distribution (represented by NormalDist()) for the given confidence using the inverse of the cumulative distribution function (inv_cdf).

  • Produces the confidence interval based on the sample's standard deviation and mean.


This assumes the sample size is big enough (let's say more than ~100 points) in order to use the standard normal distribution rather than the student's t distribution to compute the z value.

How to split a string in Java

Use:

String[] result = yourString.split("-");
if (result.length != 2) 
     throw new IllegalArgumentException("String not in correct format");

This will split your string into two parts. The first element in the array will be the part containing the stuff before the -, and the second element in the array will contain the part of your string after the -.

If the array length is not 2, then the string was not in the format: string-string.

Check out the split() method in the String class.

How to change the color of a SwitchCompat from AppCompat library

AppCompat tinting attributs:

First, you should take a look to appCompat lib article there and to different attributs you can set:

colorPrimary: The primary branding color for the app. By default, this is the color applied to the action bar background.

colorPrimaryDark: Dark variant of the primary branding color. By default, this is the color applied to the status bar (via statusBarColor) and navigation bar (via navigationBarColor).

colorAccent: Bright complement to the primary branding color. By default, this is the color applied to framework controls (via colorControlActivated).

colorControlNormal: The color applied to framework controls in their normal state.

colorControlActivated: The color applied to framework controls in their activated (ex. checked, switch on) state.

colorControlHighlight: The color applied to framework control highlights (ex. ripples, list selectors).

colorButtonNormal: The color applied to framework buttons in their normal state.

colorSwitchThumbNormal: The color applied to framework switch thumbs in their normal state. (switch off)


If all custom switches are the same in a single activity:

With previous attributes you can define your own theme for each activity:

<style name="Theme.MyActivityTheme" parent="Theme.AppCompat.Light">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/my_awesome_color</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/my_awesome_darker_color</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
         which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight, and colorSwitchThumbNormal. -->

</style>

and :

<manifest>
...
    <activity
        android:name=".MainActivity" 
        android:theme="@style/Theme.MyActivityTheme">
    </activity>
...
</manifest>

If you want to have differents custom switches in a single activity:

As widget tinting in appcompat works by intercepting any layout inflation and inserting a special tint-aware version of the widget in its place (See Chris Banes post about it) you can not apply a custom style to each switch of your layout xml file. You have to set a custom Context that will tint switch with right colors.

--

To do so for pre-5.0 you need to create a Context that overlays global theme with customs attributs and then create your switches programmatically:

ContextThemeWrapper ctw = ContextThemeWrapper(getActivity(), R.style.Color1SwitchStyle); 
SwitchCompat sc = new SwitchCompat(ctw)

As of AppCompat v22.1 you can use the following XML to apply a theme to the switch widget:

<RelativeLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    ...>

    <android.support.v7.widget.SwitchCompat
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:theme="@style/Color1SwitchStyle"/>

Your custom switch theme:

<style name="Color1SwitchStyle">
    <item name="colorControlActivated">@color/my_awesome_color</item>
</style>

--

On Android 5.0 it looks like a new view attribut comes to life : android:theme (same as one use for activity declaration in manifest). Based on another Chris Banes post, with the latter you should be able to define a custom theme directly on a view from your layout xml:

<android.support.v7.widget.SwitchCompat
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/Color1SwitchStyle"/>

Converting rows into columns and columns into rows using R

Simply use the base transpose function t, wrapped with as.data.frame:

final_df <- as.data.frame(t(starting_df))
final_df
     A    B    C    D
a    1    2    3    4
b 0.02 0.04 0.06 0.08
c Aaaa Bbbb Cccc Dddd

Above updated. As docendo discimus pointed out, t returns a matrix. As Mark suggested wrapping it with as.data.frame gets back a data frame instead of a matrix. Thanks!

How to export non-exportable private key from store

Gentil Kiwi's answer is correct. He developed this mimikatz tool that is able to retrieve non-exportable private keys.

However, his instructions are outdated. You need:

  1. Download the lastest release from https://github.com/gentilkiwi/mimikatz/releases

  2. Run the cmd with admin rights in the same machine where the certificate was requested

  3. Change to the mimikatz bin directory (Win32 or x64 version)

  4. Run mimikatz

  5. Follow the wiki instructions and the .pfx file (protected with password mimikatz) will be placed in the same folder of the mimikatz bin

What is an attribute in Java?

An abstract class is a type of class that can only be used as a base class for another class; such thus cannot be instantiated. To make a class abstract, the keyword abstract is used. Abstract classes may have one or more abstract methods that only have a header line (no method body). The method header line ends with a semicolon (;). Any class that is derived from the base class can define the method body in a way that is consistent with the header line using all the designated parameters and returning the correct data type (if the return type is not void). An abstract method acts as a place holder; all derived classes are expected to override and complete the method.

Example in Java

abstract public class Shape

{

double area;

public abstract double getArea();

}

Merge PDF files with PHP

myokyawhtun's solution worked best for me (using PHP 5.4)

You will still get an error though - I resolved using the following:

Line 269 of fpdf_tpl.php - changed the function parameters to:

function Image($file, $x=null, $y=null, $w=0, $h=0, $type='', $link='',$align='', $resize=false, $dpi=300, $palign='', $ismask=false, $imgmask=false, $border=0) { 

I also made this same change on line 898 of fpdf.php

How to add number of days to today's date?

You could extend the javascript Date object like this

Date.prototype.addDays = function(days) {
    this.setDate(this.getDate() + parseInt(days));
    return this;
};

and in your javascript code you could call

var currentDate = new Date();
// to add 4 days to current date
currentDate.addDays(4);

javascript how to create a validation error message without using alert

You need to stop the submission if an error occured:

HTML

<form name ="myform" onsubmit="return validation();"> 

JS

if (document.myform.username.value == "") {
     document.getElementById('errors').innerHTML="*Please enter a username*";
     return false;
}

Directly assigning values to C Pointers

The problem is that you're not initializing the pointer. You've created a pointer to "anywhere you want"—which could be the address of some other variable, or the middle of your code, or some memory that isn't mapped at all.

You need to create an int variable somewhere in memory for the int * variable to point at.

Your second example does this, but it does other things that aren't relevant here. Here's the simplest thing you need to do:

int main(){
    int variable;
    int *ptr = &variable;
    *ptr = 20;
    printf("%d", *ptr);
    return 0;
}

Here, the int variable isn't initialized—but that's fine, because you're just going to replace whatever value was there with 20. The key is that the pointer is initialized to point to the variable. In fact, you could just allocate some raw memory to point to, if you want:

int main(){
    void *memory = malloc(sizeof(int));
    int *ptr = (int *)memory;
    *ptr = 20;
    printf("%d", *ptr);
    free(memory);
    return 0;
}

ASP.NET MVC 404 Error Handling

Yet another solution.

Add ErrorControllers or static page to with 404 error information.

Modify your web.config (in case of controller).

<system.web>
    <customErrors mode="On" >
       <error statusCode="404" redirect="~/Errors/Error404" />
    </customErrors>
</system.web>

Or in case of static page

<system.web>
    <customErrors mode="On" >
        <error statusCode="404" redirect="~/Static404.html" />
    </customErrors>
</system.web>

This will handle both missed routes and missed actions.

Javascript Append Child AFTER Element

You can use:

if (parentGuest.nextSibling) {
  parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);
}
else {
  parentGuest.parentNode.appendChild(childGuest);
}

But as Pavel pointed out, the referenceElement can be null/undefined, and if so, insertBefore behaves just like appendChild. So the following is equivalent to the above:

parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);

How do I connect to a specific Wi-Fi network in Android programmatically?

The earlier answer works, but the solution can actually be simpler. Looping through the configured networks list is not required as you get the network id when you add the network through the WifiManager.

So the complete, simplified solution would look something like this:

WifiConfiguration wifiConfig = new WifiConfiguration();
wifiConfig.SSID = String.format("\"%s\"", ssid);
wifiConfig.preSharedKey = String.format("\"%s\"", key);

WifiManager wifiManager = (WifiManager)getSystemService(WIFI_SERVICE);
//remember id
int netId = wifiManager.addNetwork(wifiConfig);
wifiManager.disconnect();
wifiManager.enableNetwork(netId, true);
wifiManager.reconnect();

  07:30:00    17:00:00          1.5                 8  [=((A2-A1)*24)-A3]

If you subtract one time value from another the result you get will represent the fraction of 24 hours, so if you multiply the result with 24 you get the value represented in hours.

In other words: the operation is mutiply, but the meaning is to change the format of the number (from days to hours).

Why are there no ++ and --? operators in Python?

Clarity!

Python is a lot about clarity and no programmer is likely to correctly guess the meaning of --a unless s/he's learned a language having that construct.

Python is also a lot about avoiding constructs that invite mistakes and the ++ operators are known to be rich sources of defects. These two reasons are enough not to have those operators in Python.

The decision that Python uses indentation to mark blocks rather than syntactical means such as some form of begin/end bracketing or mandatory end marking is based largely on the same considerations.

For illustration, have a look at the discussion around introducing a conditional operator (in C: cond ? resultif : resultelse) into Python in 2005. Read at least the first message and the decision message of that discussion (which had several precursors on the same topic previously).

Trivia: The PEP frequently mentioned therein is the "Python Extension Proposal" PEP 308. LC means list comprehension, GE means generator expression (and don't worry if those confuse you, they are none of the few complicated spots of Python).

Convert string to JSON array

It's a very simple way to convert:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import com.google.gson.Gson;
import com.google.gson.JsonArray;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;


class Usuario {
private String username;
private String email;
private Integer credits;
private String twitter_username;

public String getUsername() {
    return username;
}

public void setUsername(String username) {
    this.username = username;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public Integer getCredits() {
    return credits;
}

public void setCredits(Integer credits) {
    this.credits = credits;
}

public String getTwitter_username() {
    return twitter_username;
}

public void setTwitter_username(String twitter_username) {
    this.twitter_username = twitter_username;
}

@Override
public String toString() {
    return "UserName: " + this.getUsername() + " Email: " + this.getEmail();
}

}

/*

How to break long string to multiple lines

If the long string to multiple lines confuses you. Then you may install mz-tools addin which is a freeware and has the utility which splits the line for you.

Download Mz-tools

If your string looks like below

SqlQueryString = "Insert into Employee values(" & txtEmployeeNo.Value & "','" & txtContractStartDate.Value & "','" & txtSeatNo.Value & "','" & txtFloor.Value & "','" & txtLeaves.Value & "')"

Simply select the string > right click on VBA IDE > Select MZ-tools > Split Lines

Execute Immediate within a stored procedure keeps giving insufficient priviliges error

Oracle's security model is such that when executing dynamic SQL using Execute Immediate (inside the context of a PL/SQL block or procedure), the user does not have privileges to objects or commands that are granted via role membership. Your user likely has "DBA" role or something similar. You must explicitly grant "drop table" permissions to this user. The same would apply if you were trying to select from tables in another schema (such as sys or system) - you would need to grant explicit SELECT privileges on that table to this user.

How to fix "namespace x already contains a definition for x" error? Happened after converting to VS2010

If you copy&paste your pages don't forget to rename class names. Otherwise you get this error also with "Type already defines a member called 'OnGet' with the same parameter types"

Why are iframes considered dangerous and a security risk?

The IFRAME element may be a security risk if your site is embedded inside an IFRAME on hostile site. Google "clickjacking" for more details. Note that it does not matter if you use <iframe> or not. The only real protection from this attack is to add HTTP header X-Frame-Options: DENY and hope that the browser knows its job.

In addition, IFRAME element may be a security risk if any page on your site contains an XSS vulnerability which can be exploited. In that case the attacker can expand the XSS attack to any page within the same domain that can be persuaded to load within an <iframe> on the page with XSS vulnerability. This is because content from the same origin (same domain) is allowed to access the parent content DOM (practically execute JavaScript in the "host" document). The only real protection methods from this attack is to add HTTP header X-Frame-Options: DENY and/or always correctly encode all user submitted data (that is, never have an XSS vulnerability on your site - easier said than done).

That's the technical side of the issue. In addition, there's the issue of user interface. If you teach your users to trust that URL bar is supposed to not change when they click links (e.g. your site uses a big iframe with all the actual content), then the users will not notice anything in the future either in case of actual security vulnerability. For example, you could have an XSS vulnerability within your site that allows the attacker to load content from hostile source within your iframe. Nobody could tell the difference because the URL bar still looks identical to previous behavior (never changes) and the content "looks" valid even though it's from hostile domain requesting user credentials.

If somebody claims that using an <iframe> element on your site is dangerous and causes a security risk, he does not understand what <iframe> element does, or he is speaking about possibility of <iframe> related vulnerabilities in browsers. Security of <iframe src="..."> tag is equal to <img src="..." or <a href="..."> as long there are no vulnerabilities in the browser. And if there's a suitable vulnerability, it might be possible to trigger it even without using <iframe>, <img> or <a> element, so it's not worth considering for this issue.

However, be warned that content from <iframe> can initiate top level navigation by default. That is, content within the <iframe> is allowed to automatically open a link over current page location (the new location will be visible in the address bar). The only way to avoid that is to add sandbox attribute without value allow-top-navigation. For example, <iframe sandbox="allow-forms allow-scripts" ...>. Unfortunately, sandbox also disables all plugins, always. For example, Youtube content cannot be sandboxed because Flash player is still required to view all Youtube content. No browser supports using plugins and disallowing top level navigation at the same time.

Note that X-Frame-Options: DENY also protects from rendering performance side-channel attack that can read content cross-origin (also known as "Pixel perfect Timing Attacks").
