There are many possibilities to do this in R. Here are some of them:

df <- read.table(header = TRUE, text = 'Gene   Value
A      12
A      10
B      3
B      5
B      6
C      1
D      3
D      4')

# aggregate
aggregate(df$Value, by = list(df$Gene), max)
aggregate(Value ~ Gene, data = df, max)

# tapply
tapply(df$Value, df$Gene, max)

# split + lapply
lapply(split(df, df$Gene), function(y) max(y$Value))

# plyr
require(plyr)
ddply(df, .(Gene), summarise, Value = max(Value))

# dplyr
require(dplyr)
df %>% group_by(Gene) %>% summarise(Value = max(Value))

# data.table
require(data.table)
dt <- data.table(df)
dt[ , max(Value), by = Gene]

# doBy
require(doBy)
summaryBy(Value~Gene, data = df, FUN = max)

# sqldf
require(sqldf)
sqldf("select Gene, max(Value) as Value from df group by Gene", drv = 'SQLite')

# ave
df[as.logical(ave(df$Value, df$Gene, FUN = function(x) x == max(x))),]

Here's my example crontab I always use as a template:

    # Use the hash sign to prefix a comment
    # +---------------- minute (0 - 59)
    # |  +------------- hour (0 - 23)
    # |  |  +---------- day of month (1 - 31)
    # |  |  |  +------- month (1 - 12)
    # |  |  |  |  +---- day of week (0 - 7) (Sunday=0 or 7)
    # |  |  |  |  |
    # *  *  *  *  *  command to be executed
    #--------------------------------------------------------------------------

To run my cron job every Monday, Wednesady and Friday at 7:00PM, the result will be:

      0 19 * * 1,3,5 nohup /home/lathonez/script.sh > /tmp/script.log 2>&1

java -cp CLASSPATH is necesssary if you wish to specify all code in the classpath. This is useful for debugging code.

The jarred executable format: java -jar JarFile can be used if you wish to start the app with a single short command. You can specify additional dependent jar files in your MANIFEST using space separated jars in a Class-Path entry, e.g.:

Class-Path: mysql.jar infobus.jar acme/beans.jar

Both are comparable in terms of performance.

In addition, there is something I find very useful. Use environment variables for your boost paths. (How to set environment variables in windows, link at bottom for 7,8,10) The BOOST_ROOT variable seems to be common place anymore and is set to the root path where you unzip boost.

Then in Properties, c++, general, Additional Include Directories use $(BOOST_ROOT). Then if/when you move to a newer version of the boost library you can update your environment variable to point to this newer version. As more of your projects, use boost you will not have to update the 'Additional Include Directories' for all of them.

You may also create a BOOST_LIB variable and point it to where the libs are staged. So likewise for the Linker->Additional Library Directories, you won't have to update projects. I have some old stuff built with vs10 and new stuff with vs14 so built both flavors of the boost lib to the same folder. So if I move a project from vs10 to vs14 I don't have to change the boost paths.

NOTE: If you change an environment variable it will not suddenly work in an open VS project. VS loads variables on startup. So you will have to close VS and reopen it.

x is used to print t pointer argument in hexadecimal.

A typical address when printed using %x would look like bfffc6e4 and the sane address printed using %p would be 0xbfffc6e4

Working example:

git mv ./src/images/poster_video.PNG ./src/images/poster_video.png

Run this command:

rvm get stable --auto-dotfiles

and make sure to read all the output. RVM will tell you if something is wrong, which in your case might be because GEM_HOME is set to something different then PATH.

This might not be the best method, but you can ignore the conversion error if all else fails. Mine was an issue of nulls not converting properly, so I just ignored the error and the dates came in as dates and the nulls came in as nulls, so no data quality issues--not that this would always be the case. To do this, right click on your source, click Edit, then Error Output. Go to the column that's giving you grief and under Error change it to Ignore Failure.

 WebClient client = new WebClient();
            using (Stream data = client.OpenRead(Text))
            {
                using (StreamReader reader = new StreamReader(data))
                {
                    string content = reader.ReadToEnd();
                    string pattern = @"((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\))+[\w\d:#@%/;$()~_?\+-=\\\.&]*)";
                    MatchCollection matches = Regex.Matches(content,pattern);
                    List<string> urls = new List<string>();
                    foreach (Match match in matches)
                    {
                            urls.Add(match.Value);
                    }

              }

.NetCore is a fine release from Microsoft and Visual Studio's latest version is also available for mac but there is still some limitation. Like for creating GUI based application on .net core you have to write code manually for everything. Like in older version of VS we just drag and drop the things and magic happens. But in VS latest version for mac every code has to be written manually. However you can make web application and console application easily on VS for mac.

You'll want to use either JavaScript or a server-side language like PHP, ASP...etc

(supposedly can be done with HTML <embed> tag, which makes sense, but I haven't used, since PHP...etc is so simple/common)

Javascript can work: Here's a link to someone doing something similar via javascript on stackoverflow: How do I load the contents of a text file into a javascript variable?

PHP (as example of server-side language) is the easiest way to go though:

<div><p><?php include('myFile.txt'); ?></p></div>

To use this (if you're unfamiliar with PHP), you can:

1) check if you have php on your server

2) change the file extension of your .html file to .php

3) paste the code from my PHP example somewhere in the body of your newly-renamed PHP file

You can convert type of plaintext to string:

f.write(str(plaintext) + '\n')

Use a div for your divider. It will always be centered vertically regardless to whether left and right divs are equal in height. You can reuse it anywhere on your site.

.divider{
    position:absolute;
    left:50%;
    top:10%;
    bottom:10%;
    border-left:1px solid white;
}

Check working example at http://jsfiddle.net/gtKBs/

No need to use third-party apps such as Platypus.

Just create an Apple Script with Script Editor and use the command do shell script "shell commands" for direct command calls or executable shell script files, keep the editable script file safe somewhere then export it to create an Application script. the app script is launch-able by double click or selection in bar folder.

As you state in one of your comments that the table in question is in a different database, then ownership chaining applies. I suspect there is a break in the chain somewhere - check that link for full details.

You can use File.WriteAllBytes

Yes you can change it. but in api 22 and above, using NotificationCompat.Builder and setColorized(true) :

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, context.getPackageName())
                .setContentTitle(title)
                .setContentText(message)
                .setSmallIcon(icon, level)
                .setLargeIcon(largeIcon)
                .setContentIntent(intent)
                .setColorized(true)
                .setDefaults(0)
                .setCategory(Notification.CATEGORY_SERVICE)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setPriority(NotificationCompat.PRIORITY_HIGH);

Please note that Arrays.stream(arr) create a LongStream (or IntStream, ...) instead of Stream so the map function cannot be used to modify the type. This is why .mapToLong, mapToObject, ... functions are provided.

Take a look at why-cant-i-map-integers-to-strings-when-streaming-from-an-array

This looks like Dijstra's algorithm. In any case, the time taken to run will depend on N. If it takes more than 3 seconds there isn't any way I can see of speeding it up, as all the calculations that it is doing need to be done.

Depending on what problem you're trying to solve, there might be a faster algorithm.

In JavaScript, primitive types such as integers and strings are passed by value whereas objects are passed by reference. So in order to achieve this you need to use an object:

// declare an object with property x
var obj = { x: 1 };
var aliasToObj = obj;
aliasToObj.x ++;
alert( obj.x ); // displays 2

You need to populate the empty indexes with nulls.

while (arraylist.size() < position)
{
     arraylist.add(null);
}

arraylist.add(position, object);

Use Hosts Commander. It's simple and powerful. Translated description (from russian) here.

Examples of using

hosts add another.dev 192.168.1.1 # Remote host
hosts add test.local # 127.0.0.1 used by default
hosts set myhost.dev # new comment
hosts rem *.local
hosts enable local*
hosts disable localhost

...and many others...

Or use this for different types of errors

function isError(val) {

The App_Data folder is a folder, which your asp.net worker process has files sytem rights too, but isn't published through the web server.

For example we use it to update a local CSV of a contact us form. If the preferred method of emails fails or any querying of the data source is required, the App_Data files are there.

It's not ideal, but it it's a good fall-back.

Trim just removes the trailing and leading whitespace. Use .replace(/ /g, "") if there are just spaces to be replaced.

this.maintabinfo = this.inner_view_data.replace(/ /g, "").toLowerCase();

Commons Lang has it. Or you could throw an UnsupportedOperationException.

Something I recently discovered for styling Radio Buttons AND Checkboxes. Before, I had to use jQuery and other things. But this is stupidly simple.

input[type=radio] {
    padding-left:5px;
    padding-right:5px;
    border-radius:15px;

    -webkit-appearance:button;

    border: double 2px #00F;

    background-color:#0b0095;
    color:#FFF;
    white-space: nowrap;
    overflow:hidden;

    width:15px;
    height:15px;
}

input[type=radio]:checked {
    background-color:#000;
    border-left-color:#06F;
    border-right-color:#06F;
}

input[type=radio]:hover {
    box-shadow:0px 0px 10px #1300ff;
}

You can do the same for a checkbox, obviously change the input[type=radio] to input[type=checkbox] and change border-radius:15px; to border-radius:4px;.

Hope this is somewhat useful to you.

Type in browser localhost:80//test5.php[where 80 is your port and test.php is your file name] instead of c://xampp/htdocs/test.php.

Can you change the if condition to this:

if (!is.na(comments[l])) print(comments[l]);

You can only check for NA values with is.na().

As many know, there is no need for a gem.

Steps to take:

1. Download Bootstrap
   • Direct download link Bootstrap 3.1.1
   • Or got to http://getbootstrap.com/

2. Copy

   bootstrap/dist/css/bootstrap.css
   bootstrap/dist/css/bootstrap.min.css 
   

   to: app/assets/stylesheets

3. Copy

   bootstrap/dist/js/bootstrap.js
   bootstrap/dist/js/bootstrap.min.js 
   

   to: app/assets/javascripts

4. Append to: app/assets/stylesheets/application.css

   *= require bootstrap

5. Append to: app/assets/javascripts/application.js

   //= require bootstrap

That is all. You are ready to add a new cool Bootstrap template.

Why app/ instead of vendor/?

It is important to add the files to app/assets, so in the future you'll be able to overwrite Bootstrap styles.

If later you want to add a custom.css.scss file with custom styles. You'll have something similar to this in application.css:

 *= require bootstrap                                                            
 *= require custom  

If you placed the bootstrap files in app/assets, everything works as expected. But, if you placed them in vendor/assets, the Bootstrap files will be loaded last. Like this:

<link href="/assets/custom.css?body=1" media="screen" rel="stylesheet">
<link href="/assets/bootstrap.css?body=1" media="screen" rel="stylesheet">

So, some of your customizations won't be used as the Bootstrap styles will override them.

Reason behind this

Rails will search for assets in many locations; to get a list of this locations you can do this:

$ rails console
> Rails.application.config.assets.paths

In the output you'll see that app/assets takes precedence, thus loading it first.

one more solution for this Automatically close or fade away the bootstrap alert message after 5 seconds:

This is the HTML code used to display the message:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>_x000D_
_x000D_
<div class="alert alert-danger">_x000D_
This is an example message..._x000D_
</div>_x000D_
_x000D_
_x000D_
<script type="text/javascript">_x000D_
_x000D_
$(document).ready(function () {_x000D_
 _x000D_
window.setTimeout(function() {_x000D_
    $(".alert").fadeTo(1000, 0).slideUp(1000, function(){_x000D_
        $(this).remove(); _x000D_
    });_x000D_
}, 5000);_x000D_
 _x000D_
});_x000D_
</script>

return can increase code readability:

foo <- function() {
    if (a) return(a)       
    b     
}

This worked. The first row had column names in it.

COPY wheat FROM 'wheat_crop_data.csv' DELIMITER ';' CSV HEADER

I had this exact problem and I solved it this way:

library(openxlsx) # loads library and doesn't require Java installed

your_df_list <- c("df1", "df2", ..., "dfn")

for(name in your_df_list){
  write.xlsx(x = get(name), 
             file = "your_spreadsheet_name.xlsx", 
             sheetName = name)
}

That way you won't have to create a very long list manually if you have tons of dataframes to write to Excel.

As with everything in git there are multiple ways of doing it. The two commands you used are one way of doing it. Another thing you could have done is simply stash them with git stash -u. The -u makes sure that newly added files (untracked) are also included.

The handy thing about git stash -u is that

1. it is probably the simplest (only?) single command to accomplish your goal
2. if you change your mind afterwards you get all your work back with git stash pop (it's like deleting an email in gmail where you can just undo if you change your mind afterwards)

As of your other question git reset --hard won't remove the untracked files so you would still need the git clean -f. But a git stash -u might be the most convenient.

There is something fishy going on. Probably a github bug that is not consistent (A/B testing?)

I am on windows10, using firefox. I have just copied a checkout URL and got an extra character. But only the first time. A second time it wasn't there. I had to look at my history file to see it!

here is my history:

git clone --recursive https://github.com/amzeratul/halley-template
git clone --recursive http://github.com/amzeratul/halley-template
git clone --recursive github.com/amzeratul/halley-template
git clone --recursive https://github.com/amzeratul/halley-template

the history command doesn't show the extra char. Just like it wasn't rendered when i was copy-pasting it into the terminal. You can see how i tried to remove the 's' and then the entire protocol? I was only triggered to investigate further when the backspace key moved one less character than i was expecting!

I saved my shell history file onto a machine with an hex editor and:

There i a c2 96 char inserted before the url. No idea what that is. Is it not extended ASCII (where it would be –) and it was hidden from almost every place i pasted while it was on the clipboard. The closest i've found with this hex value would be https://www.fileformat.info/info/unicode/char/c298/index.htm but i didn't see the utf prefix anywhere (again, might have been lost)

This all might be misleading as I lost the page/clipboard and am working exclusively from the saved shell history file, which might very well be missing data from the original bug/malicious injection.

Simple way to initiate the message on startup:

bot.on('ready', () => {
    bot.user.setStatus('available')
    bot.user.setPresence({
        game: {
            name: 'with depression',
            type: "STREAMING",
            url: "https://www.twitch.tv/monstercat"
        }
    });
});

You can also just declare it elsewhere after startup, to change the message as needed:

bot.user.setPresence({ game: { name: 'with depression', type: "streaming", url: "https://www.twitch.tv/monstercat"}}); 

Rxjs v 6.*

It got simplified with newer version of rxjs .

1) Operators

import {map} from 'rxjs/operators';

2) Others

import {Observable,of, from } from 'rxjs';

Instead of chaining we need to pipe . For example

Old syntax :

source.map().switchMap().subscribe()

New Syntax:

source.pipe(map(), switchMap()).subscribe()

Note: Some operators have a name change due to name collisions with JavaScript reserved words! These include:

do -> tap,

catch -> catchError

switch -> switchAll

finally -> finalize

Rxjs v 5.*

I am writing this answer partly to help myself as I keep checking docs everytime I need to import an operator . Let me know if something can be done better way.

1) import { Rx } from 'rxjs/Rx';

This imports the entire library. Then you don't need to worry about loading each operator . But you need to append Rx. I hope tree-shaking will optimize and pick only needed funcionts( need to verify ) As mentioned in comments , tree-shaking can not help. So this is not optimized way.

public cache = new Rx.BehaviorSubject('');

Or you can import individual operators .

This will Optimize your app to use only those files :

2) import { _______ } from 'rxjs/_________';

This syntax usually used for main Object like Rx itself or Observable etc.,

Keywords which can be imported with this syntax

 Observable, Observer, BehaviorSubject, Subject, ReplaySubject

3) import 'rxjs/add/observable/__________';

Update for Angular 5

With Angular 5, which uses rxjs 5.5.2+

import { empty } from 'rxjs/observable/empty';
import { concat} from 'rxjs/observable/concat';

These are usually accompanied with Observable directly. For example

Observable.from()
Observable.of()

Other such keywords which can be imported using this syntax:

concat, defer, empty, forkJoin, from, fromPromise, if, interval, merge, of, 
range, throw, timer, using, zip

4) import 'rxjs/add/operator/_________';

Update for Angular 5

With Angular 5, which uses rxjs 5.5.2+

import { filter } from 'rxjs/operators/filter';
import { map } from 'rxjs/operators/map';

These usually come in the stream after the Observable is created. Like flatMap in this code snippet:

Observable.of([1,2,3,4])
          .flatMap(arr => Observable.from(arr));

Other such keywords using this syntax:

audit, buffer, catch, combineAll, combineLatest, concat, count, debounce, delay, 
distinct, do, every, expand, filter, finally, find , first, groupBy,
ignoreElements, isEmpty, last, let, map, max, merge, mergeMap, min, pluck, 
publish, race, reduce, repeat, scan, skip, startWith, switch, switchMap, take, 
takeUntil, throttle, timeout, toArray, toPromise, withLatestFrom, zip

FlatMap: flatMap is alias to mergeMap so we need to import mergeMap to use flatMap.

Note for /add imports :

We only need to import once in whole project. So its advised to do it at a single place. If they are included in multiple files, and one of them is deleted, the build will fail for wrong reasons.

I used https://iconifier.net I uploaded my image, downloaded images zip file, added images to my server, followed the directions on the site including adding the links to my index.html and it worked. My favicon now shows on my iPhone in Safari when 'Add to home screen'

Worked for me only when path was set, i.e.:

$.cookie('name', null, {path:'/'})

You can use getDimensionPixelOffset() instead of getDimension, so you didn't have to cast to int.

int valueInPixels = getResources().getDimensionPixelOffset(R.dimen.test)

To set the disabled property to true or false use

<button [disabled]="!nextLibAvailable" (click)="showNext('library')" class=" btn btn-info btn-xs" title="Next Lib"> {{libraries.name}}">
    <i class="fa fa-chevron-right fa-fw"></i>
</button>

If the schema of id is not of type ObjectId you cannot operate with function : findbyId()

Add the python bin directory to your computer's PATH variable. Its listed under Environment Variables in Computer Properties -> Advanced Settings in Windows 7. It should be the same for Windows 8.

(Copied from this question)

In cases where I have not had control over the incoming JSON (and so cannot ensure that it includes a $type property) I have written a custom converter that just allows you to explicitly specify the concrete type:

public class Model
{
    [JsonConverter(typeof(ConcreteTypeConverter<Something>))]
    public ISomething TheThing { get; set; }
}

This just uses the default serializer implementation from Json.Net whilst explicitly specifying the concrete type.

An overview are available on this blog post. Source code is below:

public class ConcreteTypeConverter<TConcrete> : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        //assume we can convert to anything for now
        return true;
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        //explicitly specify the concrete type we want to create
        return serializer.Deserialize<TConcrete>(reader);
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        //use the default serialization - it works fine
        serializer.Serialize(writer, value);
    }
}

Taken from the angular docs v9 (https://angular.io/guide/workspace-config#alternate-build-configurations):

By default, a production configuration is defined, and the ng build command has --prod option that builds using this configuration. The production configuration sets defaults that optimize the app in a number of ways, such as bundling files, minimizing excess whitespace, removing comments and dead code, and rewriting code to use short, cryptic names ("minification").

Additionally you can compress all your deployables with @angular-builders/custom-webpack:browser builder where your custom webpack.config.js looks like that:

module.exports = {
  entry: {
  },
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: '[name].[hash].js'
  },
  plugins: [
    new CompressionPlugin({
      deleteOriginalAssets: true,
    })
  ]
};

Afterwards you will have to configure your web server to serve compressed content e.g. with nginx you have to add to your nginx.conf:

server {
    gzip on;
    gzip_types      text/plain application/xml;
    gzip_proxied    no-cache no-store private expired auth;
    gzip_min_length 1000;
    ...
}

In my case the dist folder shrank from 25 to 5 mb after just using the --prod in ng build and then further shrank to 1.5mb after compression.

As Henrik wrote you can use dblink to connect remote database and fetch result. For example:

psql dbtest
CREATE TABLE tblB (id serial, time integer);
INSERT INTO tblB (time) VALUES (5000), (2000);

psql postgres
CREATE TABLE tblA (id serial, time integer);

INSERT INTO tblA
    SELECT id, time 
    FROM dblink('dbname=dbtest', 'SELECT id, time FROM tblB')
    AS t(id integer, time integer)
    WHERE time > 1000;

TABLE tblA;
 id | time 
----+------
  1 | 5000
  2 | 2000
(2 rows)

PostgreSQL has record pseudo-type (only for function's argument or result type), which allows you query data from another (unknown) table.

Edit:

You can make it as prepared statement if you want and it works as well:

PREPARE migrate_data (integer) AS
INSERT INTO tblA
    SELECT id, time
    FROM dblink('dbname=dbtest', 'SELECT id, time FROM tblB')
    AS t(id integer, time integer)
    WHERE time > $1;

EXECUTE migrate_data(1000);
-- DEALLOCATE migrate_data;

Edit (yeah, another):

I just saw your revised question (closed as duplicate, or just very similar to this).

If my understanding is correct (postgres has tbla and dbtest has tblb and you want remote insert with local select, not remote select with local insert as above):

psql dbtest

SELECT dblink_exec
(
    'dbname=postgres',
    'INSERT INTO tbla
        SELECT id, time
        FROM dblink
        (
            ''dbname=dbtest'',
            ''SELECT id, time FROM tblb''
        )
        AS t(id integer, time integer)
        WHERE time > 1000;'
);

I don't like that nested dblink, but AFAIK I can't reference to tblB in dblink_exec body. Use LIMIT to specify top 20 rows, but I think you need to sort them using ORDER BY clause first.

You've only got a forward declaration for student in the header file; you need to place the struct declaration in the header file, not the .cpp. The method definitions will be in the .cpp (assuming you have any).

Actually there is neither ref nor out keyword equivalent in Java language as far as I know. However I've just transformed a C# code into Java that uses out parameter and will advise what I've just done. You should wrap whatever object into a wrapper class and pass the values wrapped in wrapper object instance as follows;

A Simple Example For Using Wrapper

Here is the Wrapper Class;

public class Wrapper {
    public Object ref1; // use this as ref
    public Object ref2; // use this as out

    public Wrapper(Object ref1) {
        this.ref1 = ref1;
    }
}

And here is the test code;

public class Test {

    public static void main(String[] args) {
        String abc = "abc";
        changeString(abc);
        System.out.println("Initial object: " + abc); //wont print "def"

        Wrapper w = new Wrapper(abc);
        changeStringWithWrapper(w);
        System.out.println("Updated object: " + w.ref1);
        System.out.println("Out     object: " + w.ref2);
    }

    // This won't work
    public static void changeString(String str) {
        str = "def";
    }

    // This will work
    public static void changeStringWithWrapper(Wrapper w) {
        w.ref1 = "def";
        w.ref2 = "And this should be used as out!";
    }

}

A Real World Example

A C#.NET method using out parameter

Here there is a C#.NET method that is using out keyword;

public bool Contains(T value)
{
    BinaryTreeNode<T> parent;
    return FindWithParent(value, out parent) != null;
}

private BinaryTreeNode<T> FindWithParent(T value, out BinaryTreeNode<T> parent)
{
    BinaryTreeNode<T> current = _head;
    parent = null;

    while(current != null)
    {
        int result = current.CompareTo(value);

        if (result > 0)
        {
            parent = current;
            current = current.Left;
        }
        else if (result < 0)
        {
            parent = current;
            current = current.Right;
        }
        else
        {
            break;
        }
    }

    return current;
}

Java Equivalent of the C# code that is using the out parameter

And the Java equivalent of this method with the help of wrapper class is as follows;

public boolean contains(T value) {
    BinaryTreeNodeGeneration<T> result = findWithParent(value);

    return (result != null);
}

private BinaryTreeNodeGeneration<T> findWithParent(T value) {
    BinaryTreeNode<T> current = head;
    BinaryTreeNode<T> parent = null;
    BinaryTreeNodeGeneration<T> resultGeneration = new BinaryTreeNodeGeneration<T>();
    resultGeneration.setParentNode(null);

    while(current != null) {
        int result = current.compareTo(value);

        if(result >0) {
            parent = current;
            current = current.left;
        } else if(result < 0) {
            parent = current;
            current = current.right;
        } else {
            break;
        }
    }

    resultGeneration.setChildNode(current);
    resultGeneration.setParentNode(parent);

    return resultGeneration;
}

Wrapper Class

And the wrapper class used in this Java code is as below;

public class BinaryTreeNodeGeneration<TNode extends Comparable<TNode>>  {

    private BinaryTreeNode<TNode>   parentNode;
    private BinaryTreeNode<TNode>   childNode;

    public BinaryTreeNodeGeneration() {
        this.parentNode = null;
        this.childNode = null;
    }

    public BinaryTreeNode<TNode> getParentNode() {
        return parentNode;
    }

    public void setParentNode(BinaryTreeNode<TNode> parentNode) {
        this.parentNode = parentNode;
    }

    public BinaryTreeNode<TNode> getChildNode() {
        return childNode;
    }

    public void setChildNode(BinaryTreeNode<TNode> childNode) {
        this.childNode = childNode;
    }

}

Use jQuery.data and jQuery.attr.

I'm showing them to you separately for the sake of understanding.

Alternate solution of the values check

//Duplicate Title Entry 
    $.each(ar , function (i, val) {
        if ( jQuery("input:first").val()== val) alert('VALUE FOUND'+Valuecheck);
  });

The string object has methods like startsWith, endsWith and includes methods.

• StartsWith checks whether the given string starts at the beginning or not.

• endsWith checks whether the given string is at the end or not.

• includes checks whether the given string is present at any part or not.

You can find the complete difference between these three in the bellow youtube video

https://www.youtube.com/watch?v=E-hyeSwg0PA

I think that in answer should be pointed which type of object do you get in all methods suggested above: is it Series or DataFrame.

When you get column by w.female. or w[[2]] (where, suppose, 2 is number of your column) you'll get back DataFrame. So in this case you can use DataFrame methods like .replace.

When you use .loc or iloc you get back Series, and Series don't have .replace method, so you should use methods like apply, map and so on.

There's nothing wrong with either version of your code. Whatever is causing this, that's not it.

Have you triple checked your locator? Your element definitely has name=submit not id=submit?

Another solution.

const frame = document.getElementById("my-iframe");

frame.parentNode.replaceChild(frame.cloneNode(), frame);

The principle of subqueries is not at all bad, but I don't think that you should use it in your example. If I understand correctly you want to get the maximum score for each date. In this case you should use a GROUP BY.

You can use UNION in this case

select id, name, games, goals from tblMadrid
union
select id, name, games, goals from tblBarcelona

you jsut have to maintain order of selected columns ie id, name, games, goals in both SQLs

Support for single character marker labels was added to Google Maps in version 3.21 (Aug 2015). See the new marker label API.

You can now create your label marker like this:

var marker = new google.maps.Marker({
  position: new google.maps.LatLng(result.latitude, result.longitude), 
  icon: markerIcon,
  label: {
    text: 'A'
  }
});

If you would like to see the 1 character restriction removed, please vote for this issue.

Update October 2016:

This issue was fixed and as of version 3.26.10, Google Maps natively supports multiple character labels in combination with custom icons using MarkerLabels.

This is old and will probably get buried, but this is my attempt.

I had an issue similar to @Ryan. In some cases, I needed to only check if at least 1 key was in an array, and in some cases, all needed to be present.

So I wrote this function:

/**
 * A key check of an array of keys
 * @param array $keys_to_check An array of keys to check
 * @param array $array_to_check The array to check against
 * @param bool $strict Checks that all $keys_to_check are in $array_to_check | Default: false
 * @return bool
 */
function array_keys_exist(array $keys_to_check, array $array_to_check, $strict = false) {
    // Results to pass back //
    $results = false;

    // If all keys are expected //
    if ($strict) {
        // Strict check //

        // Keys to check count //
        $ktc = count($keys_to_check);
        // Array to check count //
        $atc = count(array_intersect($keys_to_check, array_keys($array_to_check)));

        // Compare all //
        if ($ktc === $atc) {
            $results = true;
        }
    } else {
        // Loose check - to see if some keys exist //

        // Loop through all keys to check //
        foreach ($keys_to_check as $ktc) {
            // Check if key exists in array to check //
            if (array_key_exists($ktc, $array_to_check)) {
                $results = true;
                // We found at least one, break loop //
                break;
            }
        }
    }

    return $results;
}

This was a lot easier than having to write multiple || and && blocks.

does R stop no matter the N value you use? try to use small values and see if it's the mvrnorm function that is the issue or you could simply loop it on subsets. Insert the gc() function in the loop to free some RAM continuously

UAParser is one of the lightweight JavaScript Library to identify browser, engine, OS, CPU, and device type/model from userAgent string.

There's an CDN available. Here, I have included a example code to detect browser using UAParser.

<!doctype html>
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/ua-parser-js@0/dist/ua-parser.min.js"></script>
<script type="text/javascript">
    var parser = new UAParser();
    var result = parser.getResult();
    console.log(result.browser);     // {name: "Chromium", version: "15.0.874.106"}
</script>
</head>
<body>
</body>
</html>

Now you can use the value of result.browser to conditionally program your page.

Source Tutorial: How to detect browser, engine, OS, CPU, and device using JavaScript?

You could also use the RANK function

=RANK(C2,$C$2:$C$7,0)

It would return data like your example:

  | A       | B        | C
1 | name    | position | points
2 | person1 | 1        | 10
3 | person2 | 2        | 9
4 | person3 | 2        | 9
5 | person4 | 2        | 9
6 | person5 | 5        | 8
7 | person6 | 6        | 7

The 'Points' column needs to be sorted into descending order.

Thank you very much for all your answers:

• It was a bit surprising to find people who also think (like I do) that 5 parameters is a good limit for the sanity of the code.

• Generally, people tend to agree that a limit between 3 and 4 is good rule of thumb. This is reasonable as people usually have a bad time counting more than 4 things.

• As Milan points, on average people can keep more or less 7 things in their head at a time. But I think that you can't forget that, when you are designing/maintaining/studying a routine, you have to keep in mind more things than just the parameters.

• Some people consider that a routine should have as many arguments as it needs to. I agree, but only for a few specific cases (calls to OS APIs, routines where optimization is important, etc). I suggest to hide the complexity of these routines by adding a layer of abstraction just above these calls whenever possible.

• Nick has some interesting thoughts on this. If you don't want to read his comments, I summarize for you: in a nutshell, it depends:

  I hate making hard and fast rules like this because the answer changes not only depending on the size and scope of your project, but I think it changes even down to the module level. Depending on what your method is doing, or what the class is supposed to represent, it's quite possible that 2 arguments is too many and is a symptom of too much coupling.

  The moral here is don't be afraid of showing your code to your peers, discuss with them and try to "identify areas where you have low cohesion and tight coupling".

• Finally, I think wnoise much agrees with Nick, and concludes his satirical contribution with this poetical vision (see comments below) of the art of programming:

  Programming is not engineering. Organization of code is an art because it depends on human factors, which depend too much on context for any hard rule.

This version has all of the vbs code correctly escaped in the batch file. It's also created into a sub-routine, which can be called with a single line from anywhere in your batch script:

:: === Main code:

call :ZipUp "C:\Some\Path" "C:\Archive.zip"


:: === SubRoutines:

:ZipUp
::Arguments: Source_folder, destination_zip
(
    echo:Set fso = CreateObject^("Scripting.FileSystemObject"^)
    echo:InputFolder = fso.GetAbsolutePathName^(WScript.Arguments.Item^(0^)^)
    echo:ZipFile = fso.GetAbsolutePathName^(WScript.Arguments.Item^(1^)^)
    echo:
    echo:' Create empty ZIP file.
    echo:CreateObject^("Scripting.FileSystemObject"^).CreateTextFile^(ZipFile, True^).Write "PK" ^& Chr^(5^) ^& Chr^(6^) ^& String^(18, vbNullChar^)

I had faced the similar error, it is basically caused when use the ad blockers.Turn them off, and you run it easily.

Use the php's OR (||) logical operator for php isset() with multiple operator e.g

if (isset($_POST['room']) || ($_POST['cottage']) || ($_POST['villa'])) {

}

Just treat the ES6 class name the same as you would have treated the constructor name in the ES5 way. They are one and the same.

The ES6 syntax is just syntactic sugar and creates exactly the same underlying prototype, constructor function and objects.

So, in your ES6 example with:

// animal.js
class Animal {
    ...
}

var a = new Animal();

module.exports = {Animal: Animal};

You can just treat Animal like the constructor of your object (the same as you would have done in ES5). You can export the constructor. You can call the constructor with new Animal(). Everything is the same for using it. Only the declaration syntax is different. There's even still an Animal.prototype that has all your methods on it. The ES6 way really does create the same coding result, just with fancier/nicer syntax.

On the import side, this would then be used like this:

const Animal = require('./animal.js').Animal;

let a = new Animal();

This scheme exports the Animal constructor as the .Animal property which allows you to export more than one thing from that module.

If you don't need to export more than one thing, you can do this:

// animal.js
class Animal {
    ...
}

module.exports = Animal;

And, then import it with:

const Animal = require('./animal.js');

let a = new Animal();

Even you don't need to run the loop for that.

You can delete all the node_modules by using the only single command:-

npm uninstall `ls -1 node_modules | tr '/\n' ' '`

For node_modules you have to follow the below steps

1) In Command prompt -> Goto your project directory.

2) Command :npm init

3) It asks you to set up your package.json file

4) Command: npm install or npm update

you could add the following:

public float getAngle(Point target) {
    float angle = (float) Math.toDegrees(Math.atan2(target.y - y, target.x - x));

    if(angle < 0){
        angle += 360;
    }

    return angle;
}

by the way, why do you want to not use a double here?

• Add import sys as the new topline
• You misspelled "executables" on the last line.
• Remove script = on last line.

The code should now look like:

import sys
from cx_Freeze import setup, Executable

setup(
    name = "On Dijkstra's Algorithm",
    version = "3.1",
    description = "A Dijkstra's Algorithm help tool.",
    executables = [Executable("Main.py", base = "Win32GUI")])

Use the command prompt (cmd) to run python setup.py build. (Run this command from the folder containing setup.py.) Notice the build parameter we added at the end of the script call.

Dim q = From c In TableA
Select c.TableA

ObjectDumper.Write(q)

In addtion to Sinan Ünür comprehensive listing of string comparison operators, Perl 5.10 adds the smart match operator.

The smart match operator compares two items based on their type. See the chart below for the 5.10 behavior (I believe this behavior is changing slightly in 5.10.1):

perldoc perlsyn "Smart matching in detail":

The behaviour of a smart match depends on what type of thing its arguments are. It is always commutative, i.e. $a ~~ $b behaves the same as $b ~~ $a . The behaviour is determined by the following table: the first row that applies, in either order, determines the match behaviour.

  $a      $b        Type of Match Implied    Matching Code
  ======  =====     =====================    =============
  (overloading trumps everything)

  Code[+] Code[+]   referential equality     $a == $b   
  Any     Code[+]   scalar sub truth         $b->($a)   

  Hash    Hash      hash keys identical      [sort keys %$a]~~[sort keys %$b]
  Hash    Array     hash slice existence     grep {exists $a->{$_}} @$b
  Hash    Regex     hash key grep            grep /$b/, keys %$a
  Hash    Any       hash entry existence     exists $a->{$b}

  Array   Array     arrays are identical[*]

  Array   Any       array contains string    grep $_ eq $b, @$a 

  Any     undef     undefined                !defined $a

  Any     Num       numeric equality         $a == $b   

  Any     Any       string equality          $a eq $b   

+ - this must be a code reference whose prototype (if present) is not ""
(subs with a "" prototype are dealt with by the 'Code()' entry lower down) 
* - that is, each element matches the element of same index in the other
array. If a circular reference is found, we fall back to referential 
equality.   
! - either a real number, or a string that looks like a number

The "matching code" doesn't represent the real matching code, of course: it's just there to explain the intended meaning. Unlike grep, the smart match operator will short-circuit whenever it can.

Custom matching via overloading You can change the way that an object is matched by overloading the ~~ operator. This trumps the usual smart match semantics. See overload.

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process.Start("C:\\");
    }
}

If your application needs cmd arguments, use something like this:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        LaunchCommandLineApp();
    }

    /// <summary>
    /// Launch the application with some options set.
    /// </summary>
    static void LaunchCommandLineApp()
    {
        // For the example
        const string ex1 = "C:\\";
        const string ex2 = "C:\\Dir";

        // Use ProcessStartInfo class
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.FileName = "dcm2jpg.exe";
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

        try
        {
            // Start the process with the info we specified.
            // Call WaitForExit and then the using statement will close.
            using (Process exeProcess = Process.Start(startInfo))
            {
                exeProcess.WaitForExit();
            }
        }
        catch
        {
             // Log error.
        }
    }
}

For me nothing worked from suggested above, I use git pull from jenkins shell script and apparently it takes wrong user name. I spent ages before I found a way to fix it without switching to SSH.

In your the user's folder create .gitconfig file (if you don't have it already) and put your credentials in following format: https://user:[email protected], more info. After your .gitconfig file link to those credentials, in my case it was:

[credential] helper = store --file /Users/admin/.git-credentials

Now git will always use those credentials no matter what. I hope it will help someone, like it helped me.

What you appear to be looking for is not just a database program, but a database with forms, reports, etc (basically an IDE of sorts). I would recommend trying OpenOffice.org Base, which comes with the office suite. It's free and open source. It's nowhere near as polished as access, but it does pretty much the same things.

Plus, if you know access, it will be at least somewhat familiar.

http://www.openoffice.org/

EDIT: Sorry, failed to read that you are considering OpenOffice.org. With regard to stability, I've had it crash and do some "odd" things when I played with it, but Access has done the same thing. The best way to find out is to play with it a bit and see if it suits you.

I would use one repository per project. That way, the history becomes easier to browse through.

I would also check the version of the third party library I'm using, into the repository of the project using it.

Does this not work?

alias whatever='gnome-screensaver ; gnome-screensaver-command --lock'

The error is due to that you're only allowed to use pipeline steps inside the steps directive. One workaround that I know is to use the script step and wrap arbitrary pipeline script inside of it and save the result in the environment variable so that it can be used later.

So in your case:

pipeline {
    agent any
    stages {
        stage("foo") {
            steps {
                script {
                    env.FILENAME = readFile 'output.txt'
                }
                echo "${env.FILENAME}"
            }
        }
    }
}

You have to use the following code:

response.writeHead(302 , {
           'Location' : '/view/index.html' // This is your url which you want
        });
response.end();

press Ctrl + H . Then choose "File Search" tab.

additional search options

search for resources: Ctrl + Shift + R

search for Java types: Ctrl + Shift + T

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

To answer the question, getApplication() returns an Application object and getApplicationContext() returns a Context object. Based on your own observations, I would assume that the Context of both are identical (i.e. behind the scenes the Application class calls the latter function to populate the Context portion of the base class or some equivalent action takes place). It shouldn't really matter which function you call if you just need a Context.

The best solution

string PjFolder1 =
    Directory.GetParent(AppDomain.CurrentDomain.BaseDirectory).
        Parent.Parent.FullName;

Other solution

string pjFolder2 = Path.GetDirectoryName(Path.GetDirectoryName(Path.GetDirectoryName(
                System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase)));

Test it, AppDomain.CurrentDomain.BaseDirectory worked for me on past project, now I get debug folder .... the selected GOOD answer just NOT WORK!.

//Project DEBUG folder, but STILL PROJECT FOLDER
string pjDebugFolder = AppDomain.CurrentDomain.BaseDirectory;

//Visual studio folder, NOT PROJECT FOLDER
//This solutions just not work
string vsFolder = Directory.GetCurrentDirectory();
string vsFolder2 = Environment.CurrentDirectory;
string vsFolder3 = Path.GetFullPath(".\\");   

//Current PROJECT FOLDER
string ProjectFolder = 
    //Get Debug Folder object from BaseDirectory ( the same with end slash)
    Directory.GetParent(pjDebugFolder).
    Parent.//Bin Folder object
    Parent. //Project Folder object
    FullName;//Project Folder complete path

You probably mean the difference between Http Only cookies and their counter part?

Http Only cookies cannot be accessed (read from or written to) in client side JavaScript, only server side. If the Http Only flag is not set, or the cookie is created in (client side) JavaScript, the cookie can be read from and written to in (client side) JavaScript as well as server side.

I totally missed the export button at the bottom of each visualization. As for read only access...Shield from Elasticsearch might be worth exploring.

If you do run() in main method, the thread of main method will invoke the run method instead of the thread you require to run.

The start() method creates new thread and for which the run() method has to be done

Another yet simple solution is to paste these line into the build.gradle file

dependencies {

    //import of gridlayout
    compile 'com.android.support:gridlayout-v7:19.0.0'
    compile 'com.android.support:appcompat-v7:+'
}

I used to mainly deal with C++ and that is what lead me to the search of a destructor as well. I am using JAVA a lot now. What I did, and it may not be the best case for everyone, but I implemented my own destructor by reseting all the values to either 0 or there default through a function.

Example:

public myDestructor() {

variableA = 0; //INT
variableB = 0.0; //DOUBLE & FLOAT
variableC = "NO NAME ENTERED"; //TEXT & STRING
variableD = false; //BOOL

}

Ideally this won't work for all situations, but where there are global variables it will work as long as you don't have a ton of them.

I know I am not the best Java programmer, but it seems to be working for me.

Check what your environment variable DISPLAY's value is. Try running a simple X application from the command line. If it works, check DISPLAY's value for the right value.

You can experiment with different values of and environment variable on a per invocation basis by doing the following on the command line:

DISPLAY=:0.0 <your-java-executable-here>

How are you calling your program?

Starting with 1.6.4, Arduino IDE can be used to program and upload the NodeMCU board by installing the ESP8266 third-party platform package (refer https://github.com/esp8266/Arduino):

• Start Arduino, go to File > Preferences
• Add the following link to the Additional Boards Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json and press OK button
• Click Tools > Boards menu > Boards Manager, search for ESP8266 and install ESP8266 platform from ESP8266 community (and don't forget to select your ESP8266 boards from Tools > Boards menu after installation)

To install additional ESP8266WiFi library:

• Click Sketch > Include Library > Manage Libraries, search for ESP8266WiFi and then install with the latest version.

After above steps, you should compile the sketch normally.

According to the docker-compose reference,

Ports is defined as:

Expose ports. Either specify both ports (HOST:CONTAINER), or just the container port (a random host port will be chosen).

• Ports mentioned in docker-compose.yml will be shared among different services started by the docker-compose.
• Ports will be exposed to the host machine to a random port or a given port.

My docker-compose.yml looks like:

mysql:
  image: mysql:5.7
  ports:
    - "3306"

If I do docker-compose ps, it will look like:

  Name                     Command               State            Ports
-------------------------------------------------------------------------------------
  mysql_1       docker-entrypoint.sh mysqld      Up      0.0.0.0:32769->3306/tcp

Expose is defined as:

Expose ports without publishing them to the host machine - they’ll only be accessible to linked services. Only the internal port can be specified.

Ports are not exposed to host machines, only exposed to other services.

mysql:
  image: mysql:5.7
  expose:
    - "3306"

If I do docker-compose ps, it will look like:

  Name                  Command             State    Ports
---------------------------------------------------------------
 mysql_1      docker-entrypoint.sh mysqld   Up      3306/tcp

Edit

In recent versions of Docker, expose doesn't have any operational impact anymore, it is just informative. (see also)

Conceptual Schema - covers entities and relationships. Should be created first. Contrary to some of the other answers; tables are not defined here. For example a 'many to many' table is not included in a conceptual data model but is defined as a 'many to many' relationship between entities.

Logical Schema - Covers tables, attributes, keys, mandatory role constraints, and referential integrity with no regards to the physical implementation. Things like indexes are not defined, attribute types should be kept logical, e.g. text instead of varchar2. Should be created based on the conceptual schema.

Hashes are indexed using the square brackets ([]). Just as arrays. But instead of indexing with the numerical index, hashes are indexed using either the string literal you used for the key, or the symbol. So if your hash is similar to

hash = { "key1" => "value1", "key2" => "value2" }

you can access the value with

hash["key1"]

or for

hash = { :key1 => "value1", :key2 => "value2"}

or the new format supported in Ruby 1.9

hash = { key1: "value1", key2: "value2" }

you can access the value with

hash[:key1]

Best, Fastest way is

function arrayLookup(array, prop, val) {
    for (var i = 0, len = array.length; i < len; i++) {
        if (array[i].hasOwnProperty(prop) && array[i][prop] === val) {
            return array[i];
        }
    }
    return null;
}

final Properties properties = new Properties();
try (final InputStream stream =
           this.getClass().getResourceAsStream("foo.properties")) {
    properties.load(stream);
    /* or properties.loadFromXML(...) */
}

I was facing this issue, too.

The target table is a relation table, wiring two IDs from different tables. I have a UNIQUE constraint on the value combination, replacing the PK. When updating one of the values of a tuple, this error occured.

This is how the table looks like (MySQL):

CREATE TABLE my_relation_table (
  mrt_left_id BIGINT NOT NULL,
  mrt_right_id BIGINT NOT NULL,
  UNIQUE KEY uix_my_relation_table (mrt_left_id, mrt_right_id),
  FOREIGN KEY (mrt_left_id)
    REFERENCES left_table(lef_id),
  FOREIGN KEY (mrt_right_id)
    REFERENCES right_table(rig_id)
);

The Entity class for the RelationWithUnique entity looks basically like this:

@Entity
@IdClass(RelationWithUnique.class)
@Table(name = "my_relation_table")
public class RelationWithUnique implements Serializable {

  ...

  @Id
  @ManyToOne
  @JoinColumn(name = "mrt_left_id", referencedColumnName = "left_table.lef_id")
  private LeftTableEntity leftId;

  @Id
  @ManyToOne
  @JoinColumn(name = "mrt_right_id", referencedColumnName = "right_table.rig_id")
  private RightTableEntity rightId;

  ...

I fixed it by

// usually, we need to detach the object as we are updating the PK
// (rightId being part of the UNIQUE constraint) => PK
// but this would produce a duplicate entry, 
// therefore, we simply delete the old tuple and add the new one
final RelationWithUnique newRelation = new RelationWithUnique();
newRelation.setLeftId(oldRelation.getLeftId());
newRelation.setRightId(rightId);  // here, the value is updated actually
entityManager.remove(oldRelation);
entityManager.persist(newRelation);

Thanks a lot for the hint of the PK, I just missed it.

The “Prompt for workspace at startup” checkbox did not working. You can setting default workspace, Look for the folder named “configuration” in the Eclipse installation directory, and open up the “config.ini” file. You’ll edit the "osgi.instance.area.default" to supply your desired default workspace.

This is a fundamental understanding in Java, but can be a little tricky to new programmers. Do a little research on the difference between a static and instance method. The basic difference is the instance method do() is only accessible to a instance of the class foo.

You must instantiate (create an instance of) the class, creating an object, that you use to call the instance method.

I have included your example with a couple comments and example.

public class SomeName {

//this is a static method and cannot call an instance method without a object
public static void main(String[] args){

    // can't do this from this static method, no object reference
    // someMethod();

    //create instance of object
    SomeName thisObj = new SomeName();
    //call instance method using object
    thisObj.someMethod();
}

//instance method
public void someMethod(){
    System.out.print("some message...");
}

}// end class SomeName

android:gravity is used to specify how to place the content of the object within the object itself. In another word, android:gravity is used to specify the gravity of the content of the view.

android:layout_gravity is an attribution the child can supply to its parent, to specify the gravity the view within its parents.

Get the XML using Ajax call, find the main element, loop through all the element and append data in table.

Sample code

 //ajax call to load XML and parse it
        $.ajax({
            type: 'GET',
            url: 'https://res.cloudinary.com/dmsxwwfb5/raw/upload/v1591716537/book.xml',           // The file path.
            dataType: 'xml',    
            success: function(xml) {
               //find all book tags, loop them and append to table body
                $(xml).find('book').each(function() {
                    
                    // Append new data to the tbody element.
                    $('#tableBody').append(
                        '<tr>' +
                            '<td>' +
                                $(this).find('author').text() + '</td> ' +
                            '<td>' +
                                $(this).find('title').text() + '</td> ' +
                            '<td>' +
                                $(this).find('genre').text() + '</td> ' +

You can try this method also : example of removing last n number of lines.

a=0 ; while [ $a -lt 4 ];do sed -i '$ d' output.txt; a=expr $a + 1;done

Removing last 4 lines from file(output.txt).

Static classes can be useful in certain situations, but there is a potential to abuse and/or overuse them, like most language features.

As Dylan Smith already mentioned, the most obvious case for using a static class is if you have a class with only static methods. There is no point in allowing developers to instantiate such a class.

The caveat is that an overabundance of static methods may itself indicate a flaw in your design strategy. I find that when you are creating a static function, its a good to ask yourself -- would it be better suited as either a) an instance method, or b) an extension method to an interface. The idea here is that object behaviors are usually associated with object state, meaning the behavior should belong to the object. By using a static function you are implying that the behavior shouldn't belong to any particular object.

Polymorphic and interface driven design are hindered by overusing static functions -- they cannot be overriden in derived classes nor can they be attached to an interface. Its usually better to have your 'helper' functions tied to an interface via an extension method such that all instances of the interface have access to that shared 'helper' functionality.

One situation where static functions are definitely useful, in my opinion, is in creating a .Create() or .New() method to implement logic for object creation, for instance when you want to proxy the object being created,

public class Foo
{
    public static Foo New(string fooString)
    {
        ProxyGenerator generator = new ProxyGenerator();

        return (Foo)generator.CreateClassProxy
             (typeof(Foo), new object[] { fooString }, new Interceptor()); 
    }

This can be used with a proxying framework (like Castle Dynamic Proxy) where you want to intercept / inject functionality into an object, based on say, certain attributes assigned to its methods. The overall idea is that you need a special constructor because technically you are creating a copy of the original instance with special added functionality.

Image size is not depend on div height and width,

use img element in css

Here is css code that help you

div img{
         width: 100px;
         height:100px;
 }

if you want to set size by div

use this

div {
    width:100px;
    height:100px;
    overflow:hidden;
}

by this code your image show in original size but show first 100x100px overflow will hide

If you mean you want to see them like this:

WORKPLACEID NAME       ADDRESS        TELEPHONE
----------- ---------- -------------- ---------
          1 HSBC       Nugegoda Road      43434
          2 HNB Bank   Colombo Road      223423

then in SQL Plus you can set the column widths like this (for example):

column name format a10
column address format a20
column telephone format 999999999

You can also specify the line size and page size if necessary like this:

set linesize 100 pagesize 50

You do this by typing those commands into SQL Plus before running the query. Or you can put these commands and the query into a script file e.g. myscript.sql and run that. For example:

column name format a10
column address format a20
column telephone format 999999999

select name, address, telephone
from mytable;

Here is an update on your fiddle. https://jsfiddle.net/orax9d9u/1/

answer shouldn't be a pointer, the intent is obviously to hold a character. scanf takes the address of this character, so it should be called as

char answer;
scanf(" %c", &answer);

Next, your "or" statement is formed incorrectly.

if (answer == 'Y' || answer == 'y')

What you wrote originally asks to compare answer with the result of 'Y' || 'y', which I'm guessing isn't quite what you wanted to do.

I prefer to use:

string result = "myFile_" + DateTime.Now.ToFileTime() + ".txt";

What does ToFileTime() do?

Converts the value of the current DateTime object to a Windows file time.

public long ToFileTime()

A Windows file time is a 64-bit value that represents the number of 100-nanosecond intervals that have elapsed since 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC). Windows uses a file time to record when an application creates, accesses, or writes to a file.

Source: MSDN documentation - DateTime.ToFileTime Method

You have to change androidx.constraintlayout.widget.ConstraintLayout to RelativeLayout.

Sometimes npm uninstall -g packageName doesn’t work.

In this case you can delete package manually.

On Mac, go to folder /usr/local/lib/node_modules and delete the folder with the package you want. That's it. Check your list of globally installed packages with this command:

npm list -g --depth=0

I found none of these suggestions works if the onClick method doesn't return immediately. The touch event is queued by Android and the next onClick is called only after the first one is finished. (Since this is done on the one UI thread this is really normal.) I needed to use the time when the the onClick function is finished + one boolean variable to mark whether the given onClick is running. Both these marker attributes are static to avoid any onClickListener to run at the same time. (If user clicks on another button) You can simple replace your OnClickListener to this class and instead of implementing the onClick method you need to implement the abstract oneClick() method.

    abstract public class OneClickListener implements OnClickListener {

    private static boolean started = false;
    private static long lastClickEndTime = 0;

    /* (non-Javadoc)
     * @see android.view.View.OnClickListener#onClick(android.view.View)
     */
    @Override
    final public void onClick(final View v) {
        if(started || SystemClock.elapsedRealtime()-lastClickEndTime <1000 ){
            Log.d(OneClickListener.class.toString(), "Rejected double click, " + new Date().toString() );
            return; 
        }
        Log.d(OneClickListener.class.toString(), "One click, start: " + new Date().toString() );
        try{
            started = true;
            oneClick(v);
        }finally{
            started = false;
            lastClickEndTime = SystemClock.elapsedRealtime();
            Log.d(OneClickListener.class.toString(), "One click, end: " + new Date().toString() );
        }
    }

    abstract protected void oneClick(View v);
}

Along the same lines as some of the suggestions you would need to do at least the following:

• Load some CSS dynamically through JavaScript
• Craft some print-specific CSS rules
• Apply your fancy CSS rules through JavaScript

An example CSS could be as simple as this:

@media print {
  body * {
    display:none;
  }

  body .printable {
    display:block;
  }
}

Your JavaScript would then only need to apply the "printable" class to your target div and it will be the only thing visible (as long as there are no other conflicting CSS rules -- a separate exercise) when printing happens.

<script type="text/javascript">
  function divPrint() {
    // Some logic determines which div should be printed...
    // This example uses div3.
    $("#div3").addClass("printable");
    window.print();
  }
</script>

You may want to optionally remove the class from the target after printing has occurred, and / or remove the dynamically-added CSS after printing has occurred.

Below is a full working example, the only difference is that the print CSS is not loaded dynamically. If you want it to really be unobtrusive then you will need to load the CSS dynamically like in this answer.

string.replace(/^\s+|\s+$/g, "");

For the replacement string and the replacement pattern as specified by $. here a resume:

link to doc : here

"hello _there_".replace(/_(.*?)_/g, "<div>$1</div>")

Note:

If you want to have a $ in the replacement string use $$. Same as with vscode snippet system.

You can readily do this this with the input format U.u.

$now = DateTime::createFromFormat('U.u', microtime(true));
echo $now->format("m-d-Y H:i:s.u");

This produces the following output:

04-13-2015 05:56:22.082300

From the PHP manual page for date formats:

• U = Seconds since the Unix Epoch
• u = Microseconds

http://php.net/manual/en/function.date.php

Thanks goes to giggsey for pointing out a flaw in my original answer, adding number_format() to the line should fix the case of the exact second. Too bad it doesn't feel quite as elegant any more...

$now = DateTime::createFromFormat('U.u', number_format(microtime(true), 6, '.', ''));

http://php.net/manual/en/function.number-format.php

A note on time zones in response to DaVe.

Normally the createFromFormat() method will use the local time zone if one is not specified.

http://php.net/manual/en/datetime.createfromformat.php

However, the technique described here is initialising the DateTime object using microtime() which returns the number of seconds elapsed since the Unix Epoch (01 Jan 1970 00:00:00 GMT).

http://php.net/manual/en/function.microtime.php

This means that the DateTime object is implicitly initialised to UTC, which is fine for server internal tasks that just want to track elapsed time.

If you need to display the time for a particular time zone then you need to set it accordingly. However, this should be done as a separate step after the initialisation (not using the third parameter of createFromFormat()) because of the reasons discussed above.

The setTimeZone() method can be used to accomplish this requirement.

http://php.net/manual/en/datetime.settimezone.php

As an example:

$now = DateTime::createFromFormat('U.u', number_format(microtime(true), 6, '.', ''));
echo $now->format("m-d-Y H:i:s.u") . '<br>';

$local = $now->setTimeZone(new DateTimeZone('Australia/Canberra'));
echo $local->format("m-d-Y H:i:s.u") . '<br>';

Produces the following output:

10-29-2015 00:40:09.433818
10-29-2015 11:40:09.433818

Note that if you want to input into mysql, the time format needs to be:

format("Y-m-d H:i:s.u")

Adding my solution for Net Framework and NetCore.

I used this for my Net Framework implementation:

public static class EnumerationExtension
{
    public static string Description( this Enum value )
    {
        // get attributes  
        var field = value.GetType().GetField( value.ToString() );
        var attributes = field.GetCustomAttributes( typeof( DescriptionAttribute ), false );

        // return description
        return attributes.Any() ? ( (DescriptionAttribute)attributes.ElementAt( 0 ) ).Description : "Description Not Found";
    }
}

This doesn't work for NetCore so I modified it to do this:

public static class EnumerationExtension
{
    public static string Description( this Enum value )
    {
        // get attributes  
        var field = value.GetType().GetField( value.ToString() );
        var attributes = field.GetCustomAttributes( false );

        // Description is in a hidden Attribute class called DisplayAttribute
        // Not to be confused with DisplayNameAttribute
        dynamic displayAttribute = null;

        if (attributes.Any())
        {
            displayAttribute = attributes.ElementAt( 0 );
        }

        // return description
        return displayAttribute?.Description ?? "Description Not Found";
    }
}

Enumeration Example:

public enum ExportTypes
{
    [Display( Name = "csv", Description = "text/csv" )]
    CSV = 0
}

Sample Usage for either static added:

var myDescription = myEnum.Description();

Is this what you're looking for? You place you CSS between style tags in the HTML document header. I'm guessing for iPhone it's webkit so it should work.

<html>
<head>
    <style type="text/css">
    .title { color: blue; text-decoration: bold; text-size: 1em; }
    .author { color: gray; }
    </style>
</head>
<body>
    <p>
    <span class="title">La super bonne</span>
    <span class="author">proposée par Jérém</span>
    </p>
</body>
</html>

Your onCreate() method has several huge flaws:

1) onCreate prepares your Activity - so nothing that you do here will be made visible to the user until this method finishes! For example - you will never be able to alter a TextView's text here more than ONE time as only the last change will be drawn and thus visible to the user!

2) Keep in mind that an Android program will - by default - run in ONE thread only! Thus: never use Thread.sleep() or Thread.wait() in your main thread which is responsible for your UI! (read "Keep your App Responsive" for further information!)

What your initialization of your Activity does is:

• for no reason you create a new TextView object t!
• you pick your layout's TextView in the variable t later.
• you set the text of t (but keep in mind: it will be displayed only after onCreate() finishes and the main event loop of your application runs!)
• you wait for 10 seconds within your onCreate method - this must never be done as it stops all UI activity and will definitely force an ANR (Application Not Responding, see link above!)
• then you set another text - this one will be displayed as soon as your onCreate() method finishes and several other Activity lifecycle methods have been processed!

The solution:

1. Set text only once in onCreate() - this must be the first text that should be visible.

2. Create a Runnable and a Handler

   private final Runnable mUpdateUITimerTask = new Runnable() {
       public void run() {
           // do whatever you want to change here, like:
           t.setText("Second text to display!");
       }
   };
   private final Handler mHandler = new Handler();
   

3. install this runnable as a handler, possible in onCreate() (but read my advice below):

   // run the mUpdateUITimerTask's run() method in 10 seconds from now
   mHandler.postDelayed(mUpdateUITimerTask, 10 * 1000);
   

Advice: be sure you know an Activity's lifecycle! If you do stuff like that in onCreate()this will only happen when your Activity is created the first time! Android will possibly keep your Activity alive for a longer period of time, even if it's not visible! When a user "starts" it again - and it is still existing - you will not see your first text anymore!

=> Always install handlers in onResume() and disable them in onPause()! Otherwise you will get "updates" when your Activity is not visible at all! In your case, if you want to see your first text again when it is re-activated, you must set it in onResume(), not onCreate()!

Problem seems that you are not handling GET requests appropriately or directly posting the data without first getting the form.

When you first access the page, client will send GET request, in that case you should send html with appropriate form.

Later, user fills up the form and sends POST request with form data.

Your view should be:

def deposit(request,account_num):
   if request.method == 'POST':
      form_=AccountForm(request.POST or None, instance=account)
      if form.is_valid(): 
          #handle form data
          return HttpResponseRedirect("/history/" + account_num + "/")
      else:
         #handle when form not valid
    else:
       #handle when request is GET (or not POST)
       form_=AccountForm(instance=account)

    return render_to_response('history.html',
                          {'account_form': form},
                          context_instance=RequestContext(request))

Just read the docs:

This exception is thrown when no initial context implementation can be created. The policy of how an initial context implementation is selected is described in the documentation of the InitialContext class.

This exception can be thrown during any interaction with the InitialContext, not only when the InitialContext is constructed. For example, the implementation of the initial context might lazily retrieve the context only when actual methods are invoked on it. The application should not have any dependency on when the existence of an initial context is determined.

But this is explained much better in the docs for InitialContext

What is the difference between Attribute and Property?
What is the difference between Feature and Function? What is the difference between Characteristic and Character? What is the difference between Act and Behavior?

Its just a change in context.

Object,Product,Personality,Person

A Person Acts in a Behavior. A Personality has Characteristics of a given Character. A Product has Feature that derive Functionality. An Object had Attributes that give it Properties.

To set all FormGroup values use, setValue:

this.myFormGroup.setValue({
  formControlName1: myValue1, 
  formControlName2: myValue2
});

To set only some values, use patchValue:

this.myFormGroup.patchValue({
  formControlName1: myValue1, 
  // formControlName2: myValue2 (can be omitted)
});

With this second technique, not all values need to be supplied and fields whos values were not set will not be affected.

I used

View.inflate(getContext(), R.layout.whatever, null)

The using of View.inflate prevents the warning of using null at getLayoutInflater().inflate().

Here is how I check if string is blank. By 'blank' I mean a string that is either empty or contains only space/newline characters.

struct MyString {
  static func blank(text: String) -> Bool {
    let trimmed = text.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines)
    return trimmed.isEmpty
  }
}

How to use:

MyString.blank(" ") // true

You can use like this:

@Transactional(propagation = Propagation.REQUIRES_NEW)
public EventMessage<ModificaOperativitaRapporto> activate(EventMessage<ModificaOperativitaRapporto> eventMessage) {
//here some transaction related code
}

You can use this thing also:

public interface TransactionStatus extends SavepointManager {
    boolean isNewTransaction();
    boolean hasSavepoint();
    void setRollbackOnly();
    boolean isRollbackOnly();
    void flush();
    boolean isCompleted();
}

You can always use Hash#key? to check if the key is present in a hash or not.

If not it will return you false

hash =  { one: 1, two:2 }

hash.key?(:one)
#=> true

hash.key?(:four)
#=> false

Generating the Gradle Wrapper

Project build gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

// Running 'gradle wrapper' will generate gradlew - Getting gradle wrapper working and using it will save you a lot of pain.
task wrapper(type: Wrapper) {
    gradleVersion = '2.2' 
}

// Look Google doesn't use Maven Central, they use jcenter now.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Then at the command-line run

gradle wrapper

If you're missing gradle on your system install it or the above won't work. On a Mac it is best to install via Homebrew.

brew install gradle

After you have successfully run the wrapper task and generated gradlew, don't use your system gradle. It will save you a lot of headaches.

./gradlew assemble

What about the gradle plugin seen above?

com.android.tools.build:gradle:1.0.1

You should set the version to be the latest and you can check the tools page and edit the version accordingly.

See what Android Studio generates

The addition of gradle and the newest Android Studio have changed project layout dramatically. If you have an older project I highly recommend creating a clean one with the latest Android Studio and see what Google considers the standard project.

Android Studio has facilities for importing older projects which can also help.

GetThreadId returns the ID of a given native thread. There are ways to make it work with managed threads, I'm sure, all you need to find is the thread handle and pass it to that function.

GetCurrentThreadId returns the ID of the current thread.

GetCurrentThreadId has been deprecated as of .NET 2.0: the recommended way is the Thread.CurrentThread.ManagedThreadId property.

A png is a bitmap image style and an SVG is a vector-based graphics design which supports bitmaps so it's not as if it would convert the image to vectors, just an image embedded in a vector-based format. You could do this using http://www.inkscape.org/ which is free. It would embed it, however it also has a Live Trace like engine which will try to convert it to paths if you wish (using potrace). See live trace in adobe illustrator (commericial) is an example:

A comparison between a number and a string use to be false, so, cast you selected value to a string within ngOnInit and it will work.

I had same issue, I filled the mat-select with an enum, using

Object.keys(MyAwesomeEnum).filter(k => !isNaN(Number(k)));

and I had the enum value I wanted to select...

I spent few hours struggling my mind trying to identify why it wasn't working. And I did it just after rendering all the variables being used in the mat-select, the keys collection and the selected... if you have ["0","1","2"] and you want to select 1 (which is a number) 1=="1" is false and because of that nothing is selected.

so, the solution is to cast you selected value to a string within ngOnInit and it will work.

DO NOT USE THIS ANSWER. The URL is pointing at jQuery 1.11 (and always will).

Credits to Basic for above snippet

http://code.jquery.com/jquery-latest.min.js is the minified version, always up-to-date.

My solution inspired here goes as follows:

<form>
    <input type="text" style="position: absolute !important; left: -10000px !important; top: -10000px !important;">
    <input type="password" style="position: absolute !important; left: -10000px !important; top: -10000px !important;">
    Username: <input type="text">
    Password: <input type="password">
    <input type="submit">
</form>

It sure is ugly, feels misplaced in 2017, but it works and protects the username and password field from autofilling. Note that in Firefox (version 51 at the time of writing) it does not matter a bit what combination of name, id or autocomplete is used, be it on form or input fields. Without the first two dummy fields, autofilling will take place any time domain is matched and it will ruin your day.

I had a requirement where multiple instances of a console application needed to get an unique integer ID. It is used to identify the instance and assigned at startup. Because the .exe is started by hands, I settled on a solution using the ticks of the start time.

My reasoning was that it would be nearly impossible for the user to start two .exe in the same millisecond. This behavior is deterministic: if you have a collision, you know that the problem was that two instances were started at the same time. Methods depending on hashcode, GUID or random numbers might fail in unpredictable ways.

I set the date to 0001-01-01, add the current time and divide the ticks by 10000 (because I don't set the microseconds) to get a number that is small enough to fit into an integer.

 var now = DateTime.Now;
 var zeroDate = DateTime.MinValue.AddHours(now.Hour).AddMinutes(now.Minute).AddSeconds(now.Second).AddMilliseconds(now.Millisecond);
 int uniqueId = (int)(zeroDate.Ticks / 10000);

EDIT: There are some caveats. To make collisions unlikely, make sure that:

• The instances are started manually (more than one millisecond apart)
• The ID is generated once per instance, at startup
• The ID must only be unique in regard to other instances that are currently running
• Only a small number of IDs will ever be needed

Here is the solution using the master theorem, with readable LaTeX.

For each recurrence in the recurrence relation for binary search, we convert the problem into one subproblem, with runtime T(N/2). Therefore:

Substituting into the master theorem, we get:

Now, because is 0 and f(n) is 1, we can use the second case of the master theorem because:

This means that:

The content of the Manifest file in a JAR file created with version 1.0 of the Java Development Kit is the following.

Manifest-Version: 1.0

All the entries are as name-value pairs. The name of a header is separated from its value by a colon. The default manifest shows that it conforms to version 1.0 of the manifest specification. The manifest can also contain information about the other files that are packaged in the archive. Exactly what file information is recorded in the manifest will depend on the intended use for the JAR file. The default manifest file makes no assumptions about what information it should record about other files, so its single line contains data only about itself. Special-Purpose Manifest Headers

Depending on the intended role of the JAR file, the default manifest may have to be modified. If the JAR file is created only for the purpose of archival, then the MANIFEST.MF file is of no purpose. Most uses of JAR files go beyond simple archiving and compression and require special information to be in the manifest file. Summarized below are brief descriptions of the headers that are required for some special-purpose JAR-file functions

Applications Bundled as JAR Files: If an application is bundled in a JAR file, the Java Virtual Machine needs to be told what the entry point to the application is. An entry point is any class with a public static void main(String[] args) method. This information is provided in the Main-Class header, which has the general form:

Main-Class: classname

The value classname is to be replaced with the application's entry point.

Download Extensions: Download extensions are JAR files that are referenced by the manifest files of other JAR files. In a typical situation, an applet will be bundled in a JAR file whose manifest references a JAR file (or several JAR files) that will serve as an extension for the purposes of that applet. Extensions may reference each other in the same way. Download extensions are specified in the Class-Path header field in the manifest file of an applet, application, or another extension. A Class-Path header might look like this, for example:

Class-Path: servlet.jar infobus.jar acme/beans.jar

With this header, the classes in the files servlet.jar, infobus.jar, and acme/beans.jar will serve as extensions for purposes of the applet or application. The URLs in the Class-Path header are given relative to the URL of the JAR file of the applet or application.

Package Sealing: A package within a JAR file can be optionally sealed, which means that all classes defined in that package must be archived in the same JAR file. A package might be sealed to ensure version consistency among the classes in your software or as a security measure. To seal a package, a Name header needs to be added for the package, followed by a Sealed header, similar to this:

Name: myCompany/myPackage/
Sealed: true

The Name header's value is the package's relative pathname. Note that it ends with a '/' to distinguish it from a filename. Any headers following a Name header, without any intervening blank lines, apply to the file or package specified in the Name header. In the above example, because the Sealed header occurs after the Name: myCompany/myPackage header, with no blank lines between, the Sealed header will be interpreted as applying (only) to the package myCompany/myPackage.

Package Versioning: The Package Versioning specification defines several manifest headers to hold versioning information. One set of such headers can be assigned to each package. The versioning headers should appear directly beneath the Name header for the package. This example shows all the versioning headers:

Name: java/util/
Specification-Title: "Java Utility Classes" 
Specification-Version: "1.2"
Specification-Vendor: "Sun Microsystems, Inc.".
Implementation-Title: "java.util" 
Implementation-Version: "build57"
Implementation-Vendor: "Sun Microsystems, Inc."

This function does the trick

df <- stacomirtools::killfactor(df)

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

For AWS users who work with Amazon SES in conjunction with PHPMailer, this error also appears when your "from" mail sender isn't a verified sender.

To add a verified sender:

1. Log in to your Amazon AWS console: https://console.aws.amazon.com

2. Select "Amazon SES" from your list of available AWS applications

3. Select, under "Verified Senders", the "Email Addresses" --> "Verify a new email address"

4. Navigate to that new sender's email, click the confirmation e-mail's link.

And you're all set.

PDFsharp seems to allow merging multiple PDF documents into one.

And the same is also possible with ITextSharp.

You should use 'tag_name' outside of quotes; then its interpreted as a field of the record. Concatenate using '||' with the literal percent signs:

SELECT id FROM TAG_TABLE WHERE 'aaaaaaaa' LIKE '%' || tag_name || '%';

Go to File->Settings->Version Control->Subversion enter the path for your SVN executable in the General tab under Subversion configuration directory. Also, you can download a latest SVN client such as VisualSVN and point the path to the executable as mentioned above. That will most likely solve your problem.

Given returned json from your://site.com:

[{text:"Text1", val:"Value1"},
{text:"Text2", val:"Value2"},
{text:"Text3", val:"Value3"}]

Use this:

    $.getJSON("your://site.com", function(json){
            $('#select').empty();
            $('#select').append($('<option>').text("Select"));
            $.each(json, function(i, obj){
                    $('#select').append($('<option>').text(obj.text).attr('value', obj.val));
            });
    });

Also, it can be done dynamically like so...

<input [id]="input.id" [type]="input.type" [autofocus]="input.autofocus" />

Where input is

const input = {
  id: "my-input",
  type: "text",
  autofocus: true
};

Depends on what you mean by better. This works if your goal is removal of redundancy.

s='foo'
string='%s bar baz %s bar baz %s bar baz' % (3*(s,))

On my server, the nginx cache folder is at /data/nginx/cache/

So I removed it only: sudo rm -rf /data/nginx/cache/

Hope this will help anyone.

From Avinash Kumar Pankaj's example

View v;

then at oncreate method

v = new View(getActivity());

and then onlistitemclick method i wrote

public void onListItemClick(ListView listView, View view, int position,
       long id) {
   v.setBackgroundResource(0);
   view.setBackgroundResource(R.color.green);
   v = view;
}

It worked for me. Thank you.

I replaced

v = new View(getActivity());

to

v = new View(this);

and the code worked well.

It is necessary the xml files 'colors' and 'bg_key' from previous examples too, as well as ListView attribute android:background="@drawable/bg_key"

$('#dropdownid').empty();

That will remove all <option> elements underneath the dropdown element.

If you want to unselect selected items, go with the code from Russ.

OK, I discovered that you need to either avoid checking the "Git Credential Manager" checkbox during the Git for Windows installer, or (after installation) run the Bash shell as Administrator and use git config --edit --system to remove the helper = manager line so that it is no longer registered as a credential helper.

For bonus points, use git config --edit --global and insert:

Fact 1: Projects and Repositories were always synonyms on GitHub.

Fact 2: This is no longer the case.

There is a lot of confusion about Repositories and Projects. In the past both terms were used pretty much interchangeably by the users and the GitHub's very own documentation. This is reflected by some of the answers and comments here that explain the subtle differences between those terms and when the one was preferred over the other. The difference were always subtle, e.g. like the issue tracker being part of the project but not part of the repository which might be thought of as a strictly git thing etc.

Not any more.

Currently repos and projects refer to a different kinds of entities that have separate APIs:

• https://developer.github.com/v3/repos/
• https://developer.github.com/v3/projects/

Since then it is no longer correct to call the repo a project or vice versa. Note that it is often confused in the official documentation and it is unfortunate that a term that was already widely used has been chosen as the name of the new entity but this is the case and we have to live with that.

The consequence is that repos and projects are usually confused and every time you read about GitHub projects you have to wonder if it's really about the projects or about repos. Had they chosen some other name or an abbreviation like "proj" then we could know that what is discussed is the new type of entity, a precise object with concrete properties, or a general speaking repo-like projectish kind of thingy.

The term that is usually unambiguous is "project board".

What can we learn from the API

The first endpoint in the documentation of the Projects API:

• https://developer.github.com/v3/projects/#list-repository-projects

is described as: List repository projects. It means that a repository can have many projects. So those two cannot mean the same thing. It includes Response if projects are disabled:

{
  "message": "Projects are disabled for this repo",
  "documentation_url": "https://developer.github.com/v3"
}

which means that some repos can have projects disabled. Again, those cannot be the same thing when a repo can have projects disabled.

There are some other interesting endpoints:

• Create a repository project - POST /repos/:owner/:repo/projects
• Create an organization project - POST /orgs/:org/projects

but there is no:

• Create a user's project - POST /users/:user/projects

Which leads us to another difference:

1. Repositories can belong to users or organizations
2. Projects can belong to repositories or organizations

or, more importantly:

1. Projects can belong to repositories but not the other way around
2. Projects can belong to organizations but not to users
3. Repositories can belong to organizations and to users

See also:

• https://help.github.com/articles/about-project-boards/

I know it's confusing. I tried to explain it as precisely as I could.

That's not a good solution because you're relying on exceptions for control flow. In your solution it's normal to get exceptions, it's normal to have them in the log.

public String test() {
    String sql = "select ID_NMB_SRZ from codb_owner.TR_LTM_SLS_RTN where id_str_rt = '999' and ID_NMB_SRZ = '60230009999999'";
    List<String> certs = jdbc.queryForList(sql, String.class); 
    if (certs.isEmpty()) {
        return null;
    } else {
        return certs.get(0);
    }
}

I guess you want to do this in i line. It is possible (a bit of juggling though =^)

new StringBuilder(new StringBuilder("Düsseldorf - Zentrum - Günnewig Uebachs").reverse().toString().split(" - ")[0]).reverse()

tadaa, one line -> the result you want (if you split on " - " (space minus space) instead of only "-" (minus) you will loose the annoying space before the partition too =^) so "Günnewig Uebachs" instead of " Günnewig Uebachs" (with a space as first character)

Nice extra -> no need for extra JAR files in the lib folder so you can keep your application light weight.

See BigDecimal#intValue()

I would suggest adding a prepend() method to this pure Python ActiveState recipe or deriving a subclass from it. The code to do so could be a fairly efficient given that the underlying data structure for ordering is a linked-list.

Update

To prove this approach is feasible, below is code that does what's suggested. As a bonus, I also made a few additional minor changes to get to work in both Python 2.7.15 and 3.7.1.

A prepend() method has been added to the class in the recipe and has been implemented in terms of another method that's been added named move_to_end(), which was added to OrderedDict in Python 3.2.

prepend() can also be implemented directly, almost exactly as shown at the beginning of @Ashwini Chaudhary's answer—and doing so would likely result in it being slightly faster, but that's been left as an exercise for the motivated reader...

You can find the codes in the DB2 Information Center. Here's a definition of the -302 from the z/OS Information Center:

THE VALUE OF INPUT VARIABLE OR PARAMETER NUMBER position-number IS INVALID OR TOO LARGE FOR THE TARGET COLUMN OR THE TARGET VALUE

On Linux/Unix/Windows DB2, you'll look under SQL Messages to find your error message. If the code is positive, you'll look for SQLxxxxW, if it's negative, you'll look for SQLxxxxN, where xxxx is the code you're looking up.

I've colour coded this figure to ease the process.

import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)

You can have full control over the figure using these commands, to complete the answer I've add also the control over the splines:

ax.spines['top'].set_visible(False)
ax.spines['right'].set_visible(False)

# X AXIS -BORDER
ax.spines['bottom'].set_visible(False)
# BLUE
ax.set_xticklabels([])
# RED
ax.set_xticks([])
# RED AND BLUE TOGETHER
ax.axes.get_xaxis().set_visible(False)

# Y AXIS -BORDER

Article and Section are both semantic elements of HTML5. Section is block level generic section of a webpage, but relevant to our webpage content. Article is also block level, but article refers to an individual blog post, a comment, of a webpage.

Both Article and Section should include an heading elements h2-h6.

For a blog post, use following syntax for article and section.

<article role="main">
         <h1>Heading 1</h1>
         <p>Article Description</p>
         <section id="sec1">
                <h2>Section Heading</h2>
                <p>Section Description</p>
         </section>
         <section id="sec2">
                <h2>Section Heading</h2>
                <p>Section Description</p>
         </section>

Just simplifying the accepted answer, copy past the below in a Cygwin terminal and you are done:

cat <<EOF >> /bin/sudo
#!/usr/bin/bash
cygstart --action=runas "\$@"
EOF
chmod +X /bin/sudo

I figured this might come in handy for others as well :

find:

• ([A-Z])(.*)

replace:

• \L$1$2 --> will convert all letters in $1 and $2 to lowercase
  BUT
• \l$1$2 --> will only convert the first letter of $1 to lowercase and leave everything else as is

The same goes for uppercase with \U and \u

I am referring to these variables only from the C perspective.

From the perspective of the C language, all that matters is extent, scope, linkage, and access; exactly how items are mapped to different memory segments is up to the individual implementation, and that will vary. The language standard doesn't talk about memory segments at all. Most modern architectures act mostly the same way; block-scope variables and function arguments will be allocated from the stack, file-scope and static variables will be allocated from a data or code segment, dynamic memory will be allocated from a heap, some constant data will be stored in read-only segments, etc.

From the ansible docs: If a required variable has not been set, you can skip or fail using Jinja2’s defined test. For example:

tasks:

- shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
  when: foo is defined

- fail: msg="Bailing out. this play requires 'bar'"
  when: bar is not defined

So in your case, when: deployed_revision is not defined should work

There is small and useful library designed for this purposes:

dependencies {
    compile 'com.shamanland:fonticon:0.1.9'
}

Get demo on Google Play.

You can easily add font-based icon in your layout:

<com.shamanland.fonticon.FontIconView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/ic_android"
    android:textSize="@dimen/icon_size"
    android:textColor="@color/icon_color"
    />

You can inflate font-icon as Drawable from xml:

<?xml version="1.0" encoding="utf-8"?>
<font-icon
    xmlns:android="http://schemas.android.com/apk/res-auto"
    android:text="@string/ic_android"
    android:textSize="@dimen/big_icon_size"
    android:textColor="@color/green_170"
    />

Java code:

Drawable icon = FontIconDrawable.inflate(getResources(), R.xml.ic_android);

Well, there are more OS's than Unix and Windows (Portable devices, etc), and Java is known for its portability. The best practice is to use it, so the JVM could determine which one is the best for that OS.

I also faced the similar problem. I googled but couldn't find the solution. So I tried on my own and here is my solution.

Open you solution file in notepad. Make 2 changes

1. Replace "Format Version 12.00" with "Format Version 11.00" (without quotes.)
2. Replace "# Visual Studio 2012" with "# Visual Studio 2010" (without quotes.)

Hope this helps u as well..........

Dmitry's answer works fine. I just made a simple example using the same technique.

jsfiddle: http://jsfiddle.net/o895a8n8/5/

<button onclick="call()">Call Controller's method from outside</button>
<div  id="container" ng-app="" ng-controller="testController">
</div>

.

function call() {
    var scope = angular.element(document.getElementById('container')).scope();
      scope.$apply(function(){
        scope.msg = scope.msg + ' I am the newly addded message from the outside of the controller.';
    })
    alert(scope.returnHello());
}

function testController($scope) {
    $scope.msg = "Hello from a controller method.";
    $scope.returnHello = function() {
        return $scope.msg ; 
    }
}

Also make sure you using the ssh github url and not the https

Please use below code

app.use(fileUpload());

Best practices on internal and external temporary files:

Internal Cache

If you'd like to cache some data, rather than store it persistently, you should use getCacheDir() to open a File that represents the internal directory where your application should save temporary cache files.

When the device is low on internal storage space, Android may delete these cache files to recover space. However, you should not rely on the system to clean up these files for you. You should always maintain the cache files yourself and stay within a reasonable limit of space consumed, such as 1MB. When the user uninstalls your application, these files are removed.

External Cache

To open a File that represents the external storage directory where you should save cache files, call getExternalCacheDir(). If the user uninstalls your application, these files will be automatically deleted.

Similar to ContextCompat.getExternalFilesDirs(), mentioned above, you can also access a cache directory on a secondary external storage (if available) by calling ContextCompat.getExternalCacheDirs().

Tip: To preserve file space and maintain your app's performance, it's important that you carefully manage your cache files and remove those that aren't needed anymore throughout your app's lifecycle.

Problems with other answers:

• unsafe JSON.parse
• no response code checking

All of the answers here use JSON.parse() in an unsafe way. You should always put all calls to JSON.parse() in a try/catch block especially when you parse JSON coming from an external source, like you do here.

You can use request to parse the JSON automatically which wasn't mentioned here in other answers. There is already an answer using request module but it uses JSON.parse() to manually parse JSON - which should always be run inside a try {} catch {} block to handle errors of incorrect JSON or otherwise the entire app will crash. And incorrect JSON happens, trust me.

Other answers that use http also use JSON.parse() without checking for exceptions that can happen and crash your application.

Below I'll show few ways to handle it safely.

All examples use a public GitHub API so everyone can try that code safely.

Example with request

Here's a working example with request that automatically parses JSON:

'use strict';
var request = require('request');

var url = 'https://api.github.com/users/rsp';

request.get({
    url: url,
    json: true,
    headers: {'User-Agent': 'request'}
  }, (err, res, data) => {
    if (err) {
      console.log('Error:', err);
    } else if (res.statusCode !== 200) {
      console.log('Status:', res.statusCode);
    } else {
      // data is already parsed as JSON:
      console.log(data.html_url);
    }
});

Example with http and try/catch

This uses https - just change https to http if you want HTTP connections:

'use strict';
var https = require('https');

var options = {
    host: 'api.github.com',
    path: '/users/rsp',
    headers: {'User-Agent': 'request'}
};

https.get(options, function (res) {
    var json = '';
    res.on('data', function (chunk) {
        json += chunk;
    });
    res.on('end', function () {
        if (res.statusCode === 200) {
            try {
                var data = JSON.parse(json);
                // data is available here:
                console.log(data.html_url);
            } catch (e) {
                console.log('Error parsing JSON!');
            }
        } else {
            console.log('Status:', res.statusCode);
        }
    });
}).on('error', function (err) {
      console.log('Error:', err);
});

Example with http and tryjson

This example is similar to the above but uses the tryjson module. (Disclaimer: I am the author of that module.)

'use strict';
var https = require('https');
var tryjson = require('tryjson');

var options = {
    host: 'api.github.com',
    path: '/users/rsp',
    headers: {'User-Agent': 'request'}
};

https.get(options, function (res) {
    var json = '';

    res.on('data', function (chunk) {
        json += chunk;
    });

    res.on('end', function () {
        if (res.statusCode === 200) {
            var data = tryjson.parse(json);
            console.log(data ? data.html_url : 'Error parsing JSON!');
        } else {
            console.log('Status:', res.statusCode);
        }
    });
}).on('error', function (err) {
      console.log('Error:', err);
});

Summary

The example that uses request is the simplest. But if for some reason you don't want to use it then remember to always check the response code and to parse JSON safely.

If:

• you want multiple, but not all, worksheets, and
• you want a single df as an output

Then, you can pass a list of worksheet names. Which you could populate manually:

import pandas as pd
    
path = "C:\\Path\\To\\Your\\Data\\"
file = "data.xlsx"
sheet_lst_wanted = ["01_SomeName","05_SomeName","12_SomeName"] # tab names from Excel

### import and compile data ###
    
# read all sheets from list into an ordered dictionary    
dict_temp = pd.read_excel(path+file, sheet_name= sheet_lst_wanted)

# concatenate the ordered dict items into a dataframe
df = pd.concat(dict_temp, axis=0, ignore_index=True)

OR

A bit of automation is possible if your desired worksheets have a common naming convention that also allows you to differentiate from unwanted sheets:

# substitute following block for the sheet_lst_wanted line in above block

import xlrd

# string common to only worksheets you want
str_like = "SomeName" 
    
### create list of sheet names in Excel file ###
xls = xlrd.open_workbook(path+file, on_demand=True)
sheet_lst = xls.sheet_names()
    
### create list of sheets meeting criteria  ###
sheet_lst_wanted = []
    
for s in sheet_lst:
    # note: following conditional statement based on my sheets ending with the string defined in sheet_like
    if s[-len(str_like):] == str_like:
        sheet_lst_wanted.append(s)
    else:
        pass

They work at different levels.

The simplest way to view the difference, from a beginner perspective is that jQuery is essentially an abstract of JavaScript, so the way we design a page for JavaScript is pretty much how we will do it for jQuery. Start with the DOM then build a behavior layer on top of that. Not so with Angular.Js. The process really begins from the ground up, so the end result is the desired view.

With jQuery you do dom-manipulations, with Angular.Js you create whole web-applications.

jQuery was built to abstract away the various browser idiosyncracies, and work with the DOM without having to add IE6 checks and so on. Over time, it developed a nice, robust API which allowed us to do a lot of things, but at its core, it is meant for dealing with the DOM, finding elements, changing UI, and so on. Think of it as working directly with nuts and bolts.

Angular.Js was built as a layer on top of jQuery, to add MVC concepts to front end engineering. Instead of giving you APIs to work with DOM, Angular.Js gives you data-binding, templating, custom components (similar to jQuery UI, but declarative instead of triggering through JS) and a whole lot more. Think of it as working at a higher level, with components that you can hook together, instead of directly at the nuts and bolts level.

Additionally, Angular.Js gives you structures and concepts that apply to various projects, like Controllers, Services, and Directives. jQuery itself can be used in multiple (gazillion) ways to do the same thing. Thankfully, that is way less with Angular.Js, which makes it easier to get into and out of projects. It offers a sane way for multiple people to contribute to the same project, without having to relearn a system from scratch.

A short comparison can be this-

jQuery

• Can be easily used by those who have proper knowledge on CSS selectors
• It is a library used for DOM Manipulations
• Has nothing to do with models
• Easily manipulate the contents of a webpage
• Apply styles to make UI more attractive
• Easy DOM traversal
• Effects and animation
• Simple to make AJAX calls and
• Utilities usability
• don't have a two-way binding feature
• becomes complex and difficult to maintain when the size of a project increases
• Sometimes you have to write more code to achieve the same functionality as in Angular.Js

Angular.Js

• It is an MVVM Framework
• Used for creating SPA (Single Page Applications)
• It has key features like routing, directives, two-way data binding, models, dependency injection, unit tests etc
• is modular
• Maintainable, when project size increases
• is Fast
• Two-Way data binding REST friendly MVC-based Pattern
• Deep Linking
• Templating
• Build-in form Validation
• Dependency Injection
• Localization
• Full Testing Environment
• Server Communication

And much more

Think this helps.

Optimist (node-optimist)

Check out optimist library, it is much better than parsing command line options by hand.

Update

Optimist is deprecated. Try yargs which is an active fork of optimist.

You have to use the FormulaEvaluator, as shown here. This will return a value that is either the value present in the cell or the result of the formula if the cell contains such a formula :

FileInputStream fis = new FileInputStream("/somepath/test.xls");
Workbook wb = new HSSFWorkbook(fis); //or new XSSFWorkbook("/somepath/test.xls")
Sheet sheet = wb.getSheetAt(0);
FormulaEvaluator evaluator = wb.getCreationHelper().createFormulaEvaluator();

// suppose your formula is in B3
CellReference cellReference = new CellReference("B3"); 
Row row = sheet.getRow(cellReference.getRow());
Cell cell = row.getCell(cellReference.getCol()); 

if (cell!=null) {
    switch (evaluator.evaluateFormulaCell(cell)) {
        case Cell.CELL_TYPE_BOOLEAN:
            System.out.println(cell.getBooleanCellValue());
            break;
        case Cell.CELL_TYPE_NUMERIC:
            System.out.println(cell.getNumericCellValue());
            break;
        case Cell.CELL_TYPE_STRING:
            System.out.println(cell.getStringCellValue());
            break;
        case Cell.CELL_TYPE_BLANK:
            break;
        case Cell.CELL_TYPE_ERROR:
            System.out.println(cell.getErrorCellValue());
            break;

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

if you need the exact contant (ie the formla if the cell contains a formula), then this is shown here.

Edit : Added a few example to help you.

first you get the cell (just an example)

Row row = sheet.getRow(rowIndex+2);    
Cell cell = row.getCell(1);   

If you just want to set the value into the cell using the formula (without knowing the result) :

 String formula ="ABS((1-E"+(rowIndex + 2)+"/D"+(rowIndex + 2)+")*100)";    
 cell.setCellFormula(formula);    
 cell.setCellStyle(this.valueRightAlignStyleLightBlueBackground);

if you want to change the message if there is an error in the cell, you have to change the formula to do so, something like

IF(ISERR(ABS((1-E3/D3)*100));"N/A"; ABS((1-E3/D3)*100))

(this formula check if the evaluation return an error and then display the string "N/A", or the evaluation if this is not an error).

if you want to get the value corresponding to the formula, then you have to use the evaluator.

Hope this help,
Guillaume

    <img src="save.gif" alt="Save icon"/>        
    <br/>        
    save        
    </a>        
    </form>        

note: you can use and action and method of your choice and Id and any text starting from href="javascript: and ending to ()" but make sure that when I type the same things such as id and some text you type in your replacement in the same places(java script and HTML code).

java script code:

    var form=document.getElementById("form");        
    function submitForm()        
    {        
    form.submit();       
    }         

This is the same answer I gave over on the related: Display: Inline block - What is that space?

There’s actually a really simple way to remove whitespace from inline-block that’s both easy and semantic. It’s called a custom font with zero-width spaces, which allows you to collapse the whitespace (added by the browser for inline elements when they're on separate lines) at the font level using a very tiny font. Once you declare the font, you just change the font-family on the container and back again on the children, and voila. Like this:

@font-face{ 
    font-family: 'NoSpace';
    src: url('../Fonts/zerowidthspaces.eot');
    src: url('../Fonts/zerowidthspaces.eot?#iefix') format('embedded-opentype'),
         url('../Fonts/zerowidthspaces.woff') format('woff'),
         url('../Fonts/zerowidthspaces.ttf') format('truetype'),
         url('../Fonts/zerowidthspaces.svg#NoSpace') format('svg');
}

body {
    font-face: 'OpenSans', sans-serif;
}

.inline-container {
    font-face: 'NoSpace';
}

.inline-container > * {
    display: inline-block;
    font-face: 'OpenSans', sans-serif;
}

Suit to taste. Here’s a download to the font I just cooked up in font-forge and converted with FontSquirrel webfont generator. Took me all of 5 minutes. The css @font-face declaration is included: zipped zero-width space font. It's in Google Drive so you'll need to click File > Download to save it to your computer. You'll probably need to change the font paths as well if you copy the declaration to your main css file.

Here's what you can do using font-awesome library.

  font-family: fontAwesome;_x000D_

Fiddle here.

for Bootstrap 4, this should work for you

 $('.modal').remove();
 $('.modal-backdrop').remove();

Assuming AdvancedFormat is a bool, you need to declare and use a BooleanToVisibilityConverter:

<!-- In your resources section of the XAML -->
<BooleanToVisibilityConverter x:Key="BoolToVis" />

<!-- In your Button declaration -->
<Button
 Height="50" Width="50"
 Style="{StaticResource MyButtonStyle}"
 Command="{Binding SmallDisp}" CommandParameter="{Binding}" 
Cursor="Hand" Visibility="{Binding Path=AdvancedFormat, Converter={StaticResource BoolToVis}}"/>

Note the added Converter={StaticResource BoolToVis}.

This is a very common pattern when working with MVVM. In theory you could do the conversion yourself on the ViewModel property (i.e. just make the property itself of type Visibility) though I would prefer not to do that, since now you are messing with the separation of concerns. An item's visbility should really be up to the View.

Just to augment the accepted answer with a brief newbie-friendly short answer, you probably don't need exec.

If you're still here, the following discussion should hopefully reveal why. When you run, say,

sh -c 'command'

you run a sh instance, then start command as a child of that sh instance. When command finishes, the sh instance also finishes.

sh -c 'exec command'

runs a sh instance, then replaces that sh instance with the command binary, and runs that instead.

Of course, both of these are useless in this limited context; you simply want

command

There are some fringe situations where you want the shell to read its configuration file or somehow otherwise set up the environment as a preparation for running command. This is pretty much the sole situation where exec command is useful.

#!/bin/sh
ENVIRONMENT=$(some complex task)
exec command

This does some stuff to prepare the environment so that it contains what is needed. Once that's done, the sh instance is no longer necessary, and so it's a (minor) optimization to simply replace the sh instance with the command process, rather than have sh run it as a child process and wait for it, then exit as soon as it finishes.

Similarly, if you want to free up as much resources as possible for a heavyish command at the end of a shell script, you might want to exec that command as an optimization.

If something forces you to run sh but you really wanted to run something else, exec something else is of course a workaround to replace the undesired sh instance (like for example if you really wanted to run your own spiffy gosh instead of sh but yours isn't listed in /etc/shells so you can't specify it as your login shell).

The second use of exec to manipulate file descriptors is a separate topic. The accepted answer covers that nicely; to keep this self-contained, I'll just defer to the manual for anything where exec is followed by a redirect instead of a command name.

Got it working! I should have been building a JSONArray of JSONObjects and then add the array to a final "Addresses" JSONObject. Observe the following:

JSONObject json      = new JSONObject();
JSONArray  addresses = new JSONArray();
JSONObject address;
try
{
   int count = 15;

   for (int i=0 ; i<count ; i++)
   {
       address = new JSONObject();
       address.put("CustomerName"     , "Decepticons" + i);
       address.put("AccountId"        , "1999" + i);
       address.put("SiteId"           , "1888" + i);
       address.put("Number"            , "7" + i);
       address.put("Building"          , "StarScream Skyscraper" + i);
       address.put("Street"            , "Devestator Avenue" + i);
       address.put("City"              , "Megatron City" + i);
       address.put("ZipCode"          , "ZZ00 XX1" + i);
       address.put("Country"           , "CyberTron" + i);
       addresses.add(address);
   }
   json.put("Addresses", addresses);
}
catch (JSONException jse)
{ 

}
response.setContentType("application/json");
response.getWriter().write(json.toString());

This worked and returned valid and parse-able JSON. Hopefully this helps someone else in the future. Thanks for your help Marcel

Let's assume that You have a List<int> intList = new List<int>{1,2,3} if You want to get a max value You could do

int maxValue = intList.Max();
