Just follow these steps to transfer the apk onto the real device(with debugger key) and which is just for testing purpose. (Note: For proper distribution to the market you may need to sign your app with your keys and follow all the steps.)

1. Install your app onto the emulator.
2. Once it is installed goto DDMS, select the current running app under the devices window. This will then show all the files related to it under the file explorer.
3. Under file explorer go to data->app and select your APK (which is the package name of the app).
4. Select it and click on 'Pull a file from the device' button (the one with the save symbol).
5. This copies the APK to your system. From there you can copy the file to your real device, install and test it.

Good luck !

Actually Shay levy's answer is almost correct but i got an weird issue as i mentioned in his comment column. So i split the command into two lines and it works fine.

$Ipaddress= Read-Host "Enter the IP address:"
$Port= Read-host "Enter the port number to access:"

$t = New-Object Net.Sockets.TcpClient
$t.Connect($Ipaddress,$Port)
    if($t.Connected)
    {
        "Port $Port is operational"
    }
    else
    {
        "Port $Port is closed, You may need to contact your IT team to open it. "
    }

The fastest way if your keys are in an SSH agent:

$ ssh-add -L | ssh-keygen -E md5 -lf /dev/stdin

Each key in the agent will be printed as:

4096 MD5:8f:c9:dc:40:ec:9e:dc:65:74:f7:20:c1:29:d1:e8:5a /Users/cmcginty/.ssh/id_rsa (RSA)

Change your syntax from {{ }} to {!! !!}.

As The Alpha said in a comment above (not an answer so I thought I'd post), in Laravel 5, the {{ }} (previously non-escaped output syntax) has changed to {!! !!}. Replace {{ }} with {!! !!} and it should work.

You simply misspelled $stateParam, it should be $stateParams (with an s). That's why you get undefined ;)

In datasets having large number of columns its even better to see how many columns contain null values and how many don't.

print("No. of columns containing null values")
print(len(df.columns[df.isna().any()]))

print("No. of columns not containing null values")
print(len(df.columns[df.notna().all()]))

print("Total no. of columns in the dataframe")
print(len(df.columns))

For example in my dataframe it contained 82 columns, of which 19 contained at least one null value.

Further you can also automatically remove cols and rows depending on which has more null values
Here is the code which does this intelligently:

df = df.drop(df.columns[df.isna().sum()>len(df.columns)],axis = 1)
df = df.dropna(axis = 0).reset_index(drop=True)

Note: Above code removes all of your null values. If you want null values, process them before.

Use the backslash to escape a character. For example:

/\\d/

This will match \d instead of a numeric character

For those who are using Oracle 12.1.0 for development purposes:
I found that the above methods would have no effect on the db user: "system", because the account_status would remain in the expired-grace period.

The easiest solution was for me to use SQL Developer:
within SQL Developer, I had to go to: View / DBA / Security and then Users / System and then on the right side: Actions / Expire pw and then: Actions / Edit and I could untick the option for expired.

This cleared the account_status, it shows OPEN again, and the SQL Developer is no longer showing the ORA-28002 message.

No, you can't edit the connection string in the designer. The connection string is not part of the EDMX file it is just referenced value from the configuration file and probably because of that it is just readonly in the properties window.

Modifying configuration file is common task because you sometimes wants to make change without rebuilding the application. That is the reason why configuration files exist.

It's a shorthand for this:

<?php echo $a; ?>

They're called short tags; see example #2 in the documentation.

Why not just:

import seaborn as sns

sns.barplot(list(D.keys()), list(D.values()))

Here is some code that will manage your MongoDB connections.

var MongoClient = require('mongodb').MongoClient;
var url = require("../config.json")["MongoDBURL"]

var option = {
  db:{
    numberOfRetries : 5
  },
  server: {
    auto_reconnect: true,
    poolSize : 40,
    socketOptions: {
        connectTimeoutMS: 500
    }
  },
  replSet: {},
  mongos: {}
};

function MongoPool(){}

var p_db;

function initPool(cb){
  MongoClient.connect(url, option, function(err, db) {
    if (err) throw err;

    p_db = db;
    if(cb && typeof(cb) == 'function')
        cb(p_db);
  });
  return MongoPool;
}

MongoPool.initPool = initPool;

function getInstance(cb){
  if(!p_db){
    initPool(cb)
  }
  else{
    if(cb && typeof(cb) == 'function')
      cb(p_db);
  }
}
MongoPool.getInstance = getInstance;

module.exports = MongoPool;

When you start the server, call initPool

require("mongo-pool").initPool();

Then in any other module you can do the following:

var MongoPool = require("mongo-pool");
MongoPool.getInstance(function (db){
    // Query your MongoDB database.
});

This is based on MongoDB documentation. Take a look at it.

To check if a grammar is LL(1), one option is to construct the LL(1) parsing table and check for any conflicts. These conflicts can be

• FIRST/FIRST conflicts, where two different productions would have to be predicted for a nonterminal/terminal pair.
• FIRST/FOLLOW conflicts, where two different productions are predicted, one representing that some production should be taken and expands out to a nonzero number of symbols, and one representing that a production should be used indicating that some nonterminal should be ultimately expanded out to the empty string.
• FOLLOW/FOLLOW conflicts, where two productions indicating that a nonterminal should ultimately be expanded to the empty string conflict with one another.

Let's try this on your grammar by building the FIRST and FOLLOW sets for each of the nonterminals. Here, we get that

FIRST(X) = {a, b, z}
FIRST(Y) = {b, epsilon}
FIRST(Z) = {epsilon} 

We also have that the FOLLOW sets are

FOLLOW(X) = {$}
FOLLOW(Y) = {z}
FOLLOW(Z) = {z}

From this, we can build the following LL(1) parsing table:

    a    b    z   $
X   a    Yz   Yz  
Y        bZ   eps
Z             eps

Since we can build this parsing table with no conflicts, the grammar is LL(1).

To check if a grammar is LR(0) or SLR(1), we begin by building up all of the LR(0) configurating sets for the grammar. In this case, assuming that X is your start symbol, we get the following:

(1)
X' -> .X
X -> .Yz
X -> .a
Y -> .
Y -> .bZ

(2)
X' -> X.

(3)
X -> Y.z

(4)
X -> Yz.

(5)
X -> a.

(6)
Y -> b.Z
Z -> .

(7)
Y -> bZ.

From this, we can see that the grammar is not LR(0) because there are shift/reduce conflicts in states (1) and (6). Specifically, because we have the reduce items Z → . and Y → ., we can't tell whether to reduce the empty string to these symbols or to shift some other symbol. More generally, no grammar with ε-productions is LR(0).

However, this grammar might be SLR(1). To see this, we augment each reduction with the lookahead set for the particular nonterminals. This gives back this set of SLR(1) configurating sets:

(1)
X' -> .X
X -> .Yz [$]
X -> .a  [$]
Y -> .   [z]
Y -> .bZ [z]

(2)
X' -> X.

(3)
X -> Y.z [$]

(4)
X -> Yz. [$]

(5)
X -> a.  [$]

(6)
Y -> b.Z [z]
Z -> .   [z]

(7)
Y -> bZ. [z]

Now, we don't have any more shift-reduce conflicts. The conflict in state (1) has been eliminated because we only reduce when the lookahead is z, which doesn't conflict with any of the other items. Similarly, the conflict in (6) is gone for the same reason.

Hope this helps!

If you want to remove/clean all the values from local storage than use

localStorage.clear();

And if you want to remove the specific item from local storage than use the following code

localStorage.removeItem(key);

I just built a sandbox environment with your code and it worked for me. Here is what I used:

<html>
  <head>
    <title>test</title>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
  </head>
  <body>
    <form id="chatTickets" method="post" action="/admin/index.cfm/">
      <input id="ticketID1" type="radio" checked="checked" value="myvalue1" name="ticketID"/>
      <input id="ticketID2" type="radio" checked="checked" value="myvalue2" name="ticketID"/>
    </form>
    <a href="#" title="Load ActiveChat" id="loadActive">Load Active</a>

    <script>
      jQuery("#loadActive").click(function() {
        //I have other code in here that runs before this function call
        writeData();
      });
      function writeData() {
        jQuery("input[name='ticketID']").each(function(i) {
            jQuery(this).attr('disabled', 'disabled');
        });
      }
    </script>
  </body>
</html>

I tested in FF3.5, moving to IE8 now. And it works fine in IE8 too. What browser are you using?

Add the following css to your html and try changing the top, right, bottom, left values.

.modal {
   position: absolute;
   top: 10px;
   right: 100px;
   bottom: 0;
   left: 0;
   z-index: 10040;
   overflow: auto;
   overflow-y: auto;
}

Reposting the answer from our forum to help others with a similar issue:

@connection = ActiveRecord::Base.connection
result = @connection.exec_query('select tablename from system.tables')
result.each do |row|
puts row
end

One Idea:

UPDATE tbl_ClientNotes
SET ordering=ISNULL(@ordering, ordering), 
    title=ISNULL(@title, title),  
    content=ISNULL(@content, content)
WHERE id=@id

What about something like:

Alter Table Products
Add LastUpdate varchar(200) null

Do you need something more complex than this?

You can adjust the width of the popover with methods indicated above, but the best thing to do is to define the width of the content before Bootstrap sees is and does its math. For instance, I had a table, I defined it's width, then bootstrap built a popover to suit it. (Sometimes Bootstrap has trouble determining the width, and you need to step in and hold its hand)

I came here with the same Error, though one with a different origin.

It is caused by unsupported float index in 1.12.0 and newer numpy versions even if the code should be considered as valid.

An int type is expected, not a np.float64

Solution: Try to install numpy 1.11.0

sudo pip install -U numpy==1.11.0.

You need to edit the Tomcat/conf/server.xml and change the connector port. The connector setting should look something like this:

<Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

Just change the connector port from default 8080 to another valid port number.

1.open your xampp dir ( c:/xampp )

2.to phpMyadmin dir [C:\xampp\phpMyAdmin]

3.open [ config.inc.php ] file with any text editor

$cfg['Servers'][$i]['auth_type'] = 'config'; //replace 'config' to ‘cookie’
$cfg['Servers'][$i]['AllowNoPassword'] = true; //change ‘true’ to ‘false’.

last : save the file .

What exactly is OAuth (Open Authorization)?

OAuth allows notifying a resource provider (e.g. Facebook) that the resource owner (e.g. you) grants permission to a third-party (e.g. a Facebook Application) access to their information (e.g. the list of your friends).

If you read it stated as plainly, I would understand your confusion. So let's go with a concrete example: joining yet another social network!

Say you have an existing GMail account. You decide to join LinkedIn. Adding all of your many, many friends manually is tiresome and error-prone. You might get fed up half-way or insert typos in their e-mail address for invitation. So you might be tempted not to create an account after all.

Facing this situation, LinkedIn has the Good Idea(TM) to write a program that adds your list of friends automatically because computers are far more efficient and effective at tiresome and error prone tasks. Since joining the network is now so easy, there is no way you would refuse such an offer, now would you?

Without an API for exchanging this list of contacts, you would have to give LinkedIn the username and password to your GMail account, thereby giving them too much power.

This is where OAuth comes in. If your GMail supports the OAuth protocol, then LinkedIn can ask you to authorize them to access your GMail list of contacts.

OAuth allows for:

1. Different access levels: read-only VS read-write. This allows you to grant access to your user list or a bi-directional access to automatically synchronize your new LinkedIn friends to your GMail contacts.
2. Access granularity: you can decide to grant access to only your contact information (username, e-mail, date of birth, etc.) or to your entire list of friends, calendar and what not.
3. It allows you to manage access from the resource provider's application. If the third-party application does not provide mechanism for cancelling access, you would be stuck with them having access to your information. With OAuth, there is provision for revoking access at any time.

Will it become a de facto (standard?) in near future?

Well, although OAuth is a significant step forward, it doesn't solve problems if people don't use it correctly. For instance, if a resource provider gives only a single read-write access level to all your resources at once and doesn't provide mechanism for managing access, then there is no point to it. In other words, OAuth is a framework to provide authorization functionality and not just authentication.

In practice, it fits the social network model very well. It is especially popular for those social networks that want to allow third-party "plugins". This is an area where access to the resources is inherently necessary and is also inherently unreliable (i.e. you have little or no quality control over those applications).

I haven't seen so many other uses out in the wild. I mean, I don't know of an online financial advice firm that will access your bank records automatically, although it could technically be used that way.

This will help you. DateFormat df = new SimpleDateFormat("dd/MM/yyyy"); print (df.format(new Date());

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

For me the problem was that changing the value for this field didn`t work:

$('#cardNumber').val(maskNumber);

None of the solutions above worked for me so I investigated further and found:

According to DOM Level 2 Event Specification: The change event occurs when a control loses the input focus and its value has been modified since gaining focus. That means that change event is designed to fire on change by user interaction. Programmatic changes do not cause this event to be fired.

The solution was to add the trigger function and cause it to trigger change event like this:

$('#cardNumber').val(maskNumber).trigger('change');

The answer from @Mark Byers is best, but if you are on a version of Python < 2.7 (but at least 2.5, which is pretty old these days), you can replicate the Counter class functionality very simply via defaultdict (otherwise, for python < 2.5, three extra lines of code are needed before d[i] +=1, as in @Johnnysweb's answer).

from collections import defaultdict
class Counter():
    ITEMS = []
    def __init__(self, items):
        d = defaultdict(int)
        for i in items:
            d[i] += 1
        self.ITEMS = sorted(d.iteritems(), reverse=True, key=lambda i: i[1])
    def most_common(self, n):
        return self.ITEMS[:n]

Then, you use the class exactly as in Mark Byers's answer, i.e.:

words_to_count = (word for word in word_list if word[:1].isupper())
c = Counter(words_to_count)
print c.most_common(3)

Use directions service of Google Maps API v3. It's basically the same as directions API, but nicely packed in Google Maps API which also provides convenient way to easily render the route on the map.

Information and examples about rendering the directions route on the map can be found in rendering directions section of Google Maps API v3 documentation.

If you mean VBA, then you can use FullName, for example:

strFileFullName = ThisWorkbook.FullName

(updated as considered by the comments: the former used ActiveWorkbook.FullName could more likely be wrong, if other office files may be open(ed) and active. But in case you stored the macro in another file, as mentioned by user @user7296559 here, and really want the file name of the macro-using file, ActiveWorkbook could be the correct choice, if it is guaranteed to be active at execution time.)

Looking, it turns out on my system there is an envsubst command which is part of the gettext-base package.

So, this makes it easy:

envsubst < "source.txt" > "destination.txt"

Note if you want to use the same file for both, you'll have to use something like moreutil's sponge, as suggested by Johnny Utahh: envsubst < "source.txt" | sponge "source.txt". (Because the shell redirect will otherwise empty the file before its read.)

If l is your list and X is your value:

for i in range(len(l) + 1):
    print l[:i] + [X] + l[i:]

With the caveat of it not working in IE and some older mobile browsers, a simple object-fit: cover; is often the best option.

.cropper {
  position: relative;
  width: 100px;
  height: 100px;
  overflow: hidden;
}
.cropper img {
  position: absolute;
  width: 100%;
  height: 100%;
  object-fit: cover;
}

Without the object-fit: cover support, the image will be stretched oddly to fit the box so, if support for IE is needed, I'd recommend using one of the other answers' approach with -100% top, left, right and bottom values as a fallback.

Simply create a new external tool configuration (from Eclipse Run -> External Tools)

for example - To open Cygwin terminal on the current resource directory:

Location:

C:\cygwin\bin\mintty.exe

Working Directory:

${container_loc}

Arguments:

-i /Cygwin-Terminal.ico  
-"cygpath -p '${container_loc}' | xargs cd"

divs  = $('.testimonial')
for(ind in divs){
  div = divs[ind];
  //do whatever you want
}

here's a pure Javascript alternative:

var mydiv = document.getElementById("myDiv");
var aTag = document.createElement('a');
aTag.setAttribute('href',"yourlink.htm");
aTag.innerText = "link text";
mydiv.appendChild(aTag);

As I was searching for Scala version, all I could find was McDowell's JNA code above. I include my Scala port here, as there currently isn't anywhere more appropriate.

import com.sun.jna.platform.win32._
object jna {
    def getHome: java.io.File = {
        if (!com.sun.jna.Platform.isWindows()) {
            new java.io.File(System.getProperty("user.home"))
        }
        else {
            val pszPath: Array[Char] = new Array[Char](WinDef.MAX_PATH)
            new java.io.File(Shell32.INSTANCE.SHGetSpecialFolderPath(null, pszPath, ShlObj.CSIDL_MYDOCUMENTS, false) match {
                case true => new String(pszPath.takeWhile(c => c != '\0'))
                case _    => System.getProperty("user.home")
            })
        }
    }
}

As with the Java version, you will need to add Java Native Access, including both jar files, to your referenced libraries.

It's nice to see that JNA now makes this much easier than when the original code was posted.

Login as a superuser so that you can check all the databases and their schemas:-

sudo su - postgres

Then we can get to postgresql shell by using following command:-

psql

You can now check all the databases list by using the following command:-

\l

If you would like to check the sizes of the databases as well use:-

\l+

Press q to go back.

Once you have found your database now you can connect to that database using the following command:-

\c database_name

Once connected you can check the database tables or schema by:-

\d

Now to return back to the shell use:-

q

Now to further see the details of a certain table use:-

\d table_name

To go back to postgresql_shell press \q.

And to return back to terminal press exit.

The use of IDE is your personal preference. But personally if I had to choose, Eclipse is a widely known, trusted and certainly offers more features then Android Studio. Android Studio is a little new right now. May be it's upcoming versions keep up to Eclipse level soon.

This worked for me. Pseudocode:

// screen width and height
scr = {w:document.documentElement.clientWidth,h:document.documentElement.clientHeight}
canvas.width = scr.w
canvas.height = scr.h

Also, like devyn said, you can replace "document.documentElement.client" with "inner" for both the width and height:

**document.documentElement.client**Width
**inner**Width
**document.documentElement.client**Height
**inner**Height

and it still works.

Add this class in .css class

.scrol  { 
font: bold 14px Arial; 
border:1px solid black; 
width:100% ; 
color:#616D7E; 
height:20px; 
overflow:scroll; 
overflow-y:scroll;
overflow-x:hidden;
}

and use the class in div. like here.

<div> <p class = "scrol" id = "title">-</p></div>

I have attached image , you see the out put of the above code

I have used this:

document.onkeydown = keyboardDown;
document.onkeyup = keyboardUp;
document.oncontextmenu = function(e){
 var evt = new Object({keyCode:93});
 stopEvent(e);
 keyboardUp(evt);
}
function stopEvent(event){
 if(event.preventDefault != undefined)
  event.preventDefault();
 if(event.stopPropagation != undefined)
  event.stopPropagation();
}
function keyboardDown(e){
 ...
}
function keyboardUp(e){
 ...
}

Then I catch e.keyCode property in those two last functions - if e.keyCode == 93, I know that the user either released the right mouse button or pressed/released the Context Menu key.

Hope it helps.

What about just defining multiple patterns? They might come from a config file containing known patterns, hard coded it reads like:

List<SimpleDateFormat> knownPatterns = new ArrayList<SimpleDateFormat>();
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm.ss'Z'"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd' 'HH:mm:ss"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX"));

for (SimpleDateFormat pattern : knownPatterns) {
    try {
        // Take a try
        return new Date(pattern.parse(candidate).getTime());

    } catch (ParseException pe) {
        // Loop on
    }
}
System.err.println("No known Date format found: " + candidate);
return null;

Your method showFile() declares that it can throw an IOException. Since this is a checked exception, any call to showFile() method must handle the exception somehow. One option is to wrap the call to showFile() in a try-catch block.

 try {
     showFile();
 }
 catch(IOException e) {
    // Code to handle an IOException here
 }

It sounds to me like you want to be able to easily pass a string created using printf-style formatting to the function you already have that takes a simple string. You can create a wrapper function using stdarg.h facilities and vsnprintf() (which may not be readily available, depending on your compiler/platform):

#include <stdarg.h>
#include <stdio.h>

// a function that accepts a string:

void foo( char* s);

// You'd like to call a function that takes a format string 
//  and then calls foo():

void foofmt( char* fmt, ...)
{
    char buf[100];     // this should really be sized appropriately
                       // possibly in response to a call to vsnprintf()
    va_list vl;
    va_start(vl, fmt);

    vsnprintf( buf, sizeof( buf), fmt, vl);

    va_end( vl);

    foo( buf);
}



int main()
{
    int val = 42;

    foofmt( "Some value: %d\n", val);
    return 0;
}

For platforms that don't provide a good implementation (or any implementation) of the snprintf() family of routines, I've successfully used a nearly public domain snprintf() from Holger Weiss.

If you are including a library which depends on another library, then the order of inclusion is also important:

g++ -o MyApp MyMain.o -lMyLib1 -lMyLib2

In this case, it is okay if MyLib1 depends on MyLib2. However, if there reverse is true, you will get undefined references.

I have an answer that might be a bit less confusing for newbies like myself. You can just use map within the components render method.

render () {
   return (
       <div>
           {stations.map(station => <div key={station}> {station} </div>)} 
       </div>
   );
}

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

Verified: it works well in Docker 1.7.0.

Don't specify --pull=true when running the docker build command

From this thread on reference locally-built image using FROM at dockerfile:

If you want use the local image as the base image, pass without the option --pull=true
--pull=true will always attempt to pull a newer version of the image.

This is not possible with native HTML input elements. You can use webshim polyfill, which gives you this option by using this markup.

<input type="date" data-date-inline-picker="true" />

Here is a small demo

Here a solution, working if you want to print output while process is running or not.

I added the current working directory also, it was useful to me more than once.

Hoping the solution will help someone :).

import subprocess

def run_command(cmd_and_args, print_constantly=False, cwd=None):
"""Runs a system command.

:param cmd_and_args: the command to run with or without a Pipe (|).
:param print_constantly: If True then the output is logged in continuous until the command ended.
:param cwd: the current working directory (the directory from which you will like to execute the command)
:return: - a tuple containing the return code, the stdout and the stderr of the command
"""
output = []

process = subprocess.Popen(cmd_and_args, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, cwd=cwd)

while True:
    next_line = process.stdout.readline()
    if next_line:
        output.append(str(next_line))
        if print_constantly:
            print(next_line)
    elif not process.poll():
        break

error = process.communicate()[1]

return process.returncode, '\n'.join(output), error

The method Class.forName() is used to register the JDBC driver. A connection string is used to retrieve the connection to the database.

The way to retrieve the connection to the database is shown below. Ideally since you do not want to create multiple connections to the database, limit the connections to one and re-use the same connection. Therefore use the singleton pattern here when handling connections to the database.

Shown Below shows a connection string with the retrieval of the connection:

public class Database {
   
    private String URL = "jdbc:mysql://localhost:3306/your_db_name"; //database url
    private String username = ""; //database username
    private String password = ""; //database password
    private static Database theDatabase = new Database(); 
    private Connection theConnection;
    
    private Database(){
        try{
              Class.forName("com.mysql.jdbc.Driver"); //setting classname of JDBC Driver
              this.theConnection = DriverManager.getConnection(URL, username, password);
        } catch(Exception ex){
            System.out.println("Error Connecting to Database: "+ex);
        }
    }

    public static Database getDatabaseInstance(){
        return theDatabase;
    }
    
    public Connection getTheConnectionObject(){
        return theConnection;
    }
}

To increment versionCode only in release version do it:

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    def versionPropsFile = file('version.properties')
    def code = 1;
    if (versionPropsFile.canRead()) {
        def Properties versionProps = new Properties()

        versionProps.load(new FileInputStream(versionPropsFile))
        List<String> runTasks = gradle.startParameter.getTaskNames();
        def value = 0
        for (String item : runTasks)
        if ( item.contains("assembleRelease")) {
            value = 1;
        }
        code = Integer.parseInt(versionProps['VERSION_CODE']).intValue() + value
        versionProps['VERSION_CODE']=code.toString()
        versionProps.store(versionPropsFile.newWriter(), null)
    }
    else {
        throw new GradleException("Could not read version.properties!")
    }

    defaultConfig {
        applicationId "com.pack"
        minSdkVersion 14
        targetSdkVersion 21
        versionName "1.0."+ code
        versionCode code
    }

expects an existing c://YourProject/app/version.properties file, which you would create by hand before the first build to have VERSION_CODE=8

File version.properties:

VERSION_CODE=8

Also, to complete what @claudio said, when cherry-picking you can also use a merging strategy.

So you could something like this git cherry-pick --strategy=recursive -X theirs commit or git cherry-pick --strategy=recursive -X ours commit

The equivalent of lsof -p pid is the combined output from sysinternals handle and listdlls, ie

handle -p pid
listdlls -p pid

you can find out pid with sysinternals pslist.

private boolean isOnlyLetters(String s){
    char c=' ';
    boolean isGood=false, safe=isGood;
    int failCount=0;
    for(int i=0;i<s.length();i++){
        c = s.charAt(i);
        if(Character.isLetter(c))
            isGood=true;
        else{
            isGood=false;
            failCount+=1;
        }
    }
    if(failCount==0 && s.length()>0)
        safe=true;
    else
        safe=false;
    return safe;
}

I know it's a bit crowded. I was using it with my program and felt the desire to share it with people. It can tell if any character in a string is not a letter or not. Use it if you want something easy to clarify and look back on.

Both FetchType.LAZY and FetchType.EAGER are used to define the default fetch plan.

Unfortunately, you can only override the default fetch plan for LAZY fetching. EAGER fetching is less flexible and can lead to many performance issues.

My advice is to restrain the urge of making your associations EAGER because fetching is a query-time responsibility. So all your queries should use the fetch directive to only retrieve what's necessary for the current business case.

You have to add your jquery script to your chrome-extension project and to the background section of your manifest.json like this :

  "background":
    {
        "scripts": ["thirdParty/jquery-2.0.3.js", "background.js"]
    }

If you need jquery in a content_scripts, you have to add it in the manifest too:

"content_scripts": 
    [
        {
            "matches":["http://website*"],
            "js":["thirdParty/jquery.1.10.2.min.js", "script.js"],
            "css": ["css/style.css"],
            "run_at": "document_end"
        }
    ]

This is what I did.

Also, if I recall correctly, the background scripts are executed in a background window that you can open via chrome://extensions.

In my case, this was happening because the android/gradlew file did not have execute permission. Once granted, this worked fine

If a program forgets to free a few Megabytes before it exits the operating system will free them. But if your program runs for weeks at a time and a loop inside the program forgets to free a few bytes in each iteration you will have a mighty memory leak that will eat up all the available memory in your computer unless you reboot it on a regular basis => even small memory leaks might be bad if the program is used for a seriously big task even if it originally wasn't designed for one.

private List<GameObject> ShuffleList(List<GameObject> ActualList) {


    List<GameObject> newList = ActualList;
    List<GameObject> outList = new List<GameObject>();

    int count = newList.Count;

    while (newList.Count > 0) {

        int rando = Random.Range(0, newList.Count);

        outList.Add(newList[rando]);

        newList.RemoveAt(rando);

     

    }

    return (outList);

}

usage :

List<GameObject> GetShuffle = ShuffleList(ActualList);

T-SQL and others;

select * from t where year(Columnx) = 2010

(This was a comment to dilettante's answer but it got too long...hehe)

Of course a static is not needed here. You could use SharedPreferences to save, instead of static. Either way, the reason is to save the current progress so that its not too slow for complicated layouts. Because, in fact, after its used once, it will be rather fast later. However, I dont feel this is a good way to do it because if you have to rebuild your screen again (say onCreate gets called again), then you probably want to start over from the beginning anyhow, eliminating the need for static. Therefore, just make it an instance variable instead of static.

Here is a smaller version that runs a bit faster and might be easier to read:

int fID = 0;

public int findUnusedId() {
    while( findViewById(++fID) != null );
    return fID;
}

This above function should be sufficient. Because, as far as I can tell, android-generated IDs are in the billions, so this will probably return 1 the first time and always be quite fast. Because, it wont actually be looping past the used IDs to find an unused one. However, the loop is there should it actually find a used ID.

However, if you still want the progress saved between subsequent recreations of your app, and want to avoid using static. Here is the SharedPreferences version:

SharedPreferences sp = getSharedPreferences("your_pref_name", MODE_PRIVATE);

public int findUnusedId() {
    int fID = sp.getInt("find_unused_id", 0);
    while( findViewById(++fID) != null );
    SharedPreferences.Editor spe = sp.edit();
    spe.putInt("find_unused_id", fID);
    spe.commit();
    return fID;
}

This answer to a similar question should tell you everything you need to know about IDs with android: https://stackoverflow.com/a/13241629/693927

EDIT/FIX: Just realized I totally goofed up the save. I must have been drunk.

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

For those of us using non-ISO standard date formats, like civilian vernacular 01/01/2001 (mm/dd/YYYY), including time in a 12hour date format with am/pm marks, the following function will return a valid Date object:

function convertDate(date) {

    // # valid js Date and time object format (YYYY-MM-DDTHH:MM:SS)
    var dateTimeParts = date.split(' ');

    // # this assumes time format has NO SPACE between time and am/pm marks.
    if (dateTimeParts[1].indexOf(' ') == -1 && dateTimeParts[2] === undefined) {

        var theTime = dateTimeParts[1];

        // # strip out all except numbers and colon
        var ampm = theTime.replace(/[0-9:]/g, '');

        // # strip out all except letters (for AM/PM)
        var time = theTime.replace(/[[^a-zA-Z]/g, '');

        if (ampm == 'pm') {

            time = time.split(':');

            // # if time is 12:00, don't add 12
            if (time[0] == 12) {
                time = parseInt(time[0]) + ':' + time[1] + ':00';
            } else {
                time = parseInt(time[0]) + 12 + ':' + time[1] + ':00';
            }

        } else { // if AM

            time = time.split(':');

            // # if AM is less than 10 o'clock, add leading zero
            if (time[0] < 10) {
                time = '0' + time[0] + ':' + time[1] + ':00';
            } else {
                time = time[0] + ':' + time[1] + ':00';
            }
        }
    }
    // # create a new date object from only the date part
    var dateObj = new Date(dateTimeParts[0]);

    // # add leading zero to date of the month if less than 10
    var dayOfMonth = (dateObj.getDate() < 10 ? ("0" + dateObj.getDate()) : dateObj.getDate());

    // # parse each date object part and put all parts together
    var yearMoDay = dateObj.getFullYear() + '-' + (dateObj.getMonth() + 1) + '-' + dayOfMonth;

    // # finally combine re-formatted date and re-formatted time!
    var date = new Date(yearMoDay + 'T' + time);

    return date;
}

Usage:

date = convertDate('11/15/2016 2:00pm');

You could follow maven's standard project layout. You don't have to actually use maven, but it would make the transition easier in the future (if necessary). Plus, other developers will be used to seeing that layout, since many open source projects are layed out this way,

I use Xerces:

http://xerces.apache.org/xerces-c/

You can also add hash when page is loading:

location.hash = "noBack";

Then just handle location hash change to add another hash:

$(window).on('hashchange', function() {
    location.hash = "noBack";
});

That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.

With a non-US keyboard layout the default shortcut Ctrl+/ (Win/Linux) does not work.

I managed to change it into Ctrl+1 as per Robert's comment by writing

[
{
    "keys": ["ctrl+1"],
    "command": "toggle_comment",
    "args": { "block": false } 
}
,
{   "keys": ["ctrl+shift+1"],
    "command": "toggle_comment",
    "args": { "block": true }
}
]

to Preferences -> Key Bindings (on the right half, the user keymap).

Note that there should be only one set of brackets ('[]') at the right side; if you had there something already, copy paste this between the brackets and keep only the outermost brackets.

To check if this extensions are enabled or not, you can create a php file i.e. info.php and write the following code there:

<?php 
echo "GD: ", extension_loaded('gd') ? 'OK' : 'MISSING', '<br>';
echo "XML: ", extension_loaded('xml') ? 'OK' : 'MISSING', '<br>';
echo "zip: ", extension_loaded('zip') ? 'OK' : 'MISSING', '<br>';
?>

That's it.

Adding to All of these good answer a summary to how to initialize a structure (union and Array) in C, focused especially on the Designed Initializer.

Standard Initialization

struct point 
{
    double x;
    double y;
    double z;
}

p = {1.2, 1.3}; 

Designed Initializer

The Designed Initializer came up since the ISO C99 and is a different and more dynamic way to initialize in C when initializing struct, union or an array.

The biggest difference to standard initialization is that you don't have to declare the elements in a fixed order and you can also omit element.

From The GNU Guide:

Standard C90 requires the elements of an initializer to appear in a fixed order, the same as the order of the elements in the array or structure being initialized.

In ISO C99 you can give the elements in random order, specifying the array indices or structure field names they apply to, and GNU C allows this as an extension in C90 mode as well

Examples

1. Array Index

Standard Initialization

  int a[6] = { 0, 0, 15, 0, 29, 0 };

Designed Initialization

  int a[6] = {[4] = 29, [2] = 15 }; // or
  int a[6] = {[4]29 , [2]15 }; // or
  int widths[] = { [0 ... 9] = 1, [10 ... 99] = 2, [100] = 3 };

2. Struct or union:

Standard Initialization

struct point { int x, y; };

Designed Initialization

 struct point p = { .y = 2, .x = 3 }; or
 struct point p = { y: 2, x: 3 };

3. Combine naming elements with ordinary C initialization of successive elements:

Standard Initialization

int a[6] = { 0, v1, v2, 0, v4, 0 };

Designed Initialization

int a[6] = { [1] = v1, v2, [4] = v4 };

4. Others:

Labeling the elements of an array initializer

int whitespace[256] = { [' '] = 1, ['\t'] = 1, ['\h'] = 1,
                        ['\f'] = 1, ['\n'] = 1, ['\r'] = 1 };

write a series of ‘.fieldname’ and ‘[index]’ designators before an ‘=’ to specify a nested subobject to initialize

struct point ptarray[10] = { [2].y = yv2, [2].x = xv2, [0].x = xv0 };

I am using angular 6x and I've ended up by using below snippet. I've a scenerio where I've to find user from a task object. it contains array of users but I've to pick assigned user.

<ng-container *ngTemplateOutlet="memberTemplate; context:{o: getAssignee(task) }">
</ng-container>
<ng-template #memberTemplate let-user="o">
  <ng-container *ngIf="user">
    <div class="d-flex flex-row-reverse">
      <span class="image-block">
        <ngx-avatar placement="left" ngbTooltip="{{user.firstName}} {{user.lastName}}" class="task-assigned" value="28%" [src]="user.googleId" size="32"></ngx-avatar>
      </span>
    </div>
  </ng-container>
</ng-template>

 SELECT name, city, count(*) as qty 
 FROM stuff 
 GROUP BY name, city HAVING count(*)> 1

Will something like this work for you? What this does is query the content resolver to find the file path data that is stored for that content entry

public static String getRealPathFromUri(Context context, Uri contentUri) {
    Cursor cursor = null;
    try {
        String[] proj = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
}

This will end up giving you an absolute file path that you can construct a file uri from

Have you tried gradle cleanBuildCache?

https://developer.android.com/studio/build/build-cache.html#clear_the_build_cache

You can also login to the redis-cli and use the MONITOR command to see what queries are happening against Redis.

You can do also this:

class Program
  {
    static void Main(string[] args)
    {
      long numberToTest = 350124;
      bool isPrime = NumberIsPrime(numberToTest);
      Console.WriteLine(string.Format("Number {0} is prime? {1}", numberToTest, isPrime));
      Console.ReadLine();
    }

    private static bool NumberIsPrime(long n)
    {
      bool retVal = true;

      if (n <= 3)
      {
        retVal = n > 1;
      } else if (n % 2 == 0 || n % 3 == 0)
      {
        retVal = false;
      }

      int i = 5;

      while (i * i <= n)
      {
        if (n % i == 0 || n % (i + 2) == 0)
        {
          retVal = false;
        }
        i += 6;
      }

      return retVal;
    }
  }

If you're having troubles specifying the SDK target to Google APIs instead of the base Platform SDK just change the compileSdkVersion 19 to compileSdkVersion "Google Inc.:Google APIs:19"

First of all, I think it's usually \r\n, second of all, those are not the same on all systems. That will only work on windows. It's kind-of annoying trying to figure out how to replace new lines because different systems treat them differently (see here). You might have better luck with just \n.

Another method for Swift (without using NSString):

let percentage = 33.3333
let text = String.localizedStringWithFormat("%.02f %@", percentage, "%")

P.S. this solution is not working with CGFloat type only tested with Float & Double

since the problem is still there I though I throw in another solution. My case was that I wanted to auto deploy all pull requests to s3 for testing before merge making them accessible on [mydomain]/pull-requests/[pr number]/
(ex. www.example.com/pull-requests/822/)

To the best of my knowledge non of s3 rules scenarios would allow to have multiple projects in one bucket using html5 routing so while above most voted suggestion works for a project in root folder, it doesn't for multiple projects in own subfolders.

So I pointed my domain to my server where following nginx config did the job

location /pull-requests/ {
    try_files $uri @get_files;
}
location @get_files {
    rewrite ^\/pull-requests\/(.*) /$1 break;
    proxy_pass http://<your-amazon-bucket-url>;
    proxy_intercept_errors on;
    recursive_error_pages on;
    error_page 404 = @get_routes;
}

location @get_routes {
    rewrite ^\/(\w+)\/(.+) /$1/ break;
    proxy_pass http://<your-amazon-bucket-url>;
    proxy_intercept_errors on;
    recursive_error_pages on;
    error_page 404 = @not_found;
}

location @not_found {
    return 404;
}

it tries to get the file and if not found assumes it is html5 route and tries that. If you have a 404 angular page for not found routes you will never get to @not_found and get you angular 404 page returned instead of not found files, which could be fixed with some if rule in @get_routes or something.

I have to say I don't feel too comfortable in area of nginx config and using regex for that matter, I got this working with some trial and error so while this works I am sure there is room for improvement and please do share your thoughts.

Note: remove s3 redirection rules if you had them in S3 config.

and btw works in Safari

The key distinction is repeating a captured group instead of capturing a repeated group.

As you have already found out, the difference is that repeating a captured group captures only the last iteration. Capturing a repeated group captures all iterations.

In PCRE (PHP):

((?:\w+)+),?

Match 1, Group 1.    0-5      HELLO
Match 2, Group 1.    6-11     THERE
Match 3, Group 1.    12-20    BRUTALLY
Match 4, Group 1.    21-26    CRUEL
Match 5, Group 1.    27-32    WORLD

Since all captures are in Group 1, you only need $1 for substitution.

I used the following general form of this regular expression:

((?:{{RE}})+)

Example at regex101

For Swift 3.0+

extension String {
    func SizeOf_String( font: UIFont) -> CGSize {
        let fontAttribute = [NSFontAttributeName: font]
        let size = self.size(attributes: fontAttribute)  // for Single Line
       return size;
   }
}

Use it like...

        let Str = "ABCDEF"
        let Font =  UIFont.systemFontOfSize(19.0)
        let SizeOfString = Str.SizeOfString(font: Font!)

Use Simple math to resize the image . either you can resize ImageView or you can resize drawable image than set on ImageView . find the width and height of your bitmap which you want to set on ImageView and call the desired method. suppose your width 500 is greater than height than call method

//250 is the width you want after resize bitmap
Bitmat bmp = BitmapScaler.scaleToFitWidth(bitmap, 250) ;
ImageView image = (ImageView) findViewById(R.id.picture);
image.setImageBitmap(bmp);

You use this class for resize bitmap.

public class BitmapScaler{
// Scale and maintain aspect ratio given a desired width
// BitmapScaler.scaleToFitWidth(bitmap, 100);
 public static Bitmap scaleToFitWidth(Bitmap b, int width)
  {
    float factor = width / (float) b.getWidth();
    return Bitmap.createScaledBitmap(b, width, (int) (b.getHeight() * factor), true);
  }


  // Scale and maintain aspect ratio given a desired height
  // BitmapScaler.scaleToFitHeight(bitmap, 100);
  public static Bitmap scaleToFitHeight(Bitmap b, int height)
  {
    float factor = height / (float) b.getHeight();
    return Bitmap.createScaledBitmap(b, (int) (b.getWidth() * factor), height, true);
   }
 }

xml code is

<ImageView
android:id="@+id/picture"
android:layout_width="250dp"
android:layout_height="250dp"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp"

android:scaleType="fitcenter" />

In IntelliJ you can specify default settings for each run configuration. In Run/Debug configuration dialog (the one you use to configure heap per test) click on Defaults and JUnit. These settings will be automatically applied to each new JUnit test configuration. I guess similar setting exists for Eclipse.

However there is no simple option to transfer such settings (at least in IntelliJ) across environments. You can commit IntelliJ project files to your repository: it might work, but I do not recommend it.

You know how to set these for maven-surefire-plugin. Good. This is the most portable way (see Ptomli's answer for an example).

For the rest - you must remember that JUnit test cases are just a bunch of Java classes, not a standalone program. It is up to the runner (let it be a standalone JUnit runner, your IDE, maven-surefire-plugin to set those options. That being said there is no "portable" way to set them, so that memory settings are applied irrespective to the runner.

To give you an example: you cannot define Xmx parameter when developing a servlet - it is up to the container to define that. You can't say: "this servlet should always be run with Xmx=1G.

I totally agree with both the question and Martin's answer :). Even in Java, reading javadoc with generics is much harder than it should be due to the extra noise. This is compounded in Scala where implicit parameters are used as in the questions's example code (while the implicits do very useful collection-morphing stuff).

I don't think its a problem with the language per se - I think its more a tooling issue. And while I agree with what Jörg W Mittag says, I think looking at scaladoc (or the documentation of a type in your IDE) - it should require as little brain power as possible to grok what a method is, what it takes and returns. There shouldn't be a need to hack up a bit of algebra on a bit of paper to get it :)

For sure IDEs need a nice way to show all the methods for any variable/expression/type (which as with Martin's example can have all the generics inlined so its nice and easy to grok). I like Martin's idea of hiding the implicits by default too.

To take the example in scaladoc...

def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That

When looking at this in scaladoc I'd like the generic block [B, That] to be hidden by default as well as the implicit parameter (maybe they show if you hover a little icon with the mouse) - as its extra stuff to grok reading it which usually isn't that relevant. e.g. imagine if this looked like...

def map(f: A => B): That

nice and clear and obvious what it does. You might wonder what 'That' is, if you mouse over or click it it could expand the [B, That] text highlighting the 'That' for example.

Maybe a little icon could be used for the [] declaration and (implicit...) block so its clear there are little bits of the statement collapsed? Its hard to use a token for it, but I'll use a . for now...

def map.(f: A => B).: That

So by default the 'noise' of the type system is hidden from the main 80% of what folks need to look at - the method name, its parameter types and its return type in nice simple concise way - with little expandable links to the detail if you really care that much.

Mostly folks are reading scaladoc to find out what methods they can call on a type and what parameters they can pass. We're kinda overloading users with way too much detail right how IMHO.

Here's another example...

def orElse[A1 <: A, B1 >: B](that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Now if we hid the generics declaration its easier to read

def orElse(that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Then if folks hover over, say, A1 we could show the declaration of A1 being A1 <: A. Covariant and contravariant types in generics add lots of noise too which can be rendered in a much easier to grok way to users I think.

Response.Redirect: tells the browser that the requested page can be found at a new location. The browser then initiates another request to the new page loading its contents in the browser. This results in two requests by the browser.

Server.Transfer: It transfers execution from the first page to the second page on the server. As far as the browser client is concerned, it made one request and the initial page is the one responding with content. The benefit of this approach is one less round trip to the server from the client browser. Also, any posted form variables and query string parameters are available to the second page as well.

Find the folder containing the shared library libopencv_core.so.2.4 using the following command line.

sudo find / -name "libopencv_core.so.2.4*"

Then I got the result:

 /usr/local/lib/libopencv_core.so.2.4.

Create a file called /etc/ld.so.conf.d/opencv.conf and write to it the path to the folder where the binary is stored.For example, I wrote /usr/local/lib/ to my opencv.conf file. Run the command line as follows.

sudo ldconfig -v

Try to run the command again.

Why can't it just use AND in the ON clause? For example:

SELECT *
FROM flights
INNER JOIN airports
   ON ((airports.code = flights.fairport)
       AND (airports.code = flights.tairport))

Even same issue I faced, in browser it was showing compiled code. I have made below changes in webpack config file and it is working fine now.

 devtool: '#inline-source-map',
 debug: true,

and in loaders I kept babel-loader as first option

loaders: [
  {
    loader: "babel-loader",
    include: [path.resolve(__dirname, "src")]
  },
  { test: /\.js$/, exclude: [/app\/lib/, /node_modules/], loader: 'ng-annotate!babel' },
  { test: /\.html$/, loader: 'raw' },
  {
    test: /\.(jpe?g|png|gif|svg)$/i,
    loaders: [
      'file?hash=sha512&digest=hex&name=[hash].[ext]',
      'image-webpack?bypassOnDebug&optimizationLevel=7&interlaced=false'
    ]
  },
  {test: /\.less$/, loader: "style!css!less"},
  { test: /\.styl$/, loader: 'style!css!stylus' },
  { test: /\.css$/, loader: 'style!css' }
]

You can use fetch to do that:

fetch('some_url')
    .then(function (response) {
        switch (response.status) {
            // status "OK"
            case 200:
                return response.text();
            // status "Not Found"
            case 404:
                throw response;
        }
    })
    .then(function (template) {
        console.log(template);
    })
    .catch(function (response) {
        // "Not Found"
        console.log(response.statusText);
    });

Asynchronous with arrow function version:

(async () => {
    var response = await fetch('some_url');
    switch (response.status) {
        // status "OK"
        case 200:
            var template = await response.text();

            console.log(template);
            break;
        // status "Not Found"
        case 404:
            console.log('Not Found');
            break;
    }
})();

using jquery, you may want to get only to those with a '#'

$('a[href=#]').click(function(){return false;});

if you use the newest jquery (1.3.x), there's no need to bind it again when the page changes:

$('a[href=#]').live('click', function(){return false;});

Generic types is a compile time abstraction. At runtime all maps will have the same type Map<Object, Object>. So if you are sure that values are strings, you can cheat on java compiler:

Map<String, Object> m1 = new HashMap<String, Object>();
Map<String, String> m2 = (Map) m1;

Copying keys and values from one collection to another is redundant. But this approach is still not good, because it violates generics type safety. May be you should reconsider your code to avoid such things.

Here is what I do for any action and it works in Firefox, IE, Opera, and Safari.

<script type="text/javascript">
  $(document).ready(function(){
    doMethod();
  });
  function actionIframe(iframe)
  {
    ... do what ever ...
  }
  function doMethod()
  {   
    var iFrames = document.getElementsByTagName('iframe');

    // what ever action you want.
    function iAction()
    {
      // Iterate through all iframes in the page.
      for (var i = 0, j = iFrames.length; i < j; i++)
      {
        actionIframe(iFrames[i]);
      }
    }

    // Check if browser is Safari or Opera.
    if ($.browser.safari || $.browser.opera)
    {
      // Start timer when loaded.
      $('iframe').load(function()
      {
        setTimeout(iAction, 0);
      }
      );

      // Safari and Opera need something to force a load.
      for (var i = 0, j = iFrames.length; i < j; i++)
      {
         var iSource = iFrames[i].src;
         iFrames[i].src = '';
         iFrames[i].src = iSource;
      }
    }
    else
    {
      // For other good browsers.
      $('iframe').load(function()
      {
        actionIframe(this);
      }
      );
    }
  }
</script>

'SET' is forgotten

ALTER TABLE ONLY users ALTER COLUMN lang SET DEFAULT 'en_GB';

Here's a simple one written in VB for an ASPX page:

                If myVar > 1 Then
                    response.write("Greater than 1")
                else
                    response.write("Not!")
                End If

This will give you the difference between two dates, in milliseconds

var diff = Math.abs(date1 - date2);

In your example, it'd be

var diff = Math.abs(new Date() - compareDate);

You need to make sure that compareDate is a valid Date object.

Something like this will probably work for you

var diff = Math.abs(new Date() - new Date(dateStr.replace(/-/g,'/')));

i.e. turning "2011-02-07 15:13:06" into new Date('2011/02/07 15:13:06'), which is a format the Date constructor can comprehend.

One typical usage:

| is used to set a certain bit to 1

& is used to test or clear a certain bit

• Set a bit (where n is the bit number, and 0 is the least significant bit):

  unsigned char a |= (1 << n);

• Clear a bit:

  unsigned char b &= ~(1 << n);

• Toggle a bit:

  unsigned char c ^= (1 << n);

• Test a bit:

  unsigned char e = d & (1 << n);

Take the case of your list for example:

x | 2 is used to set bit 1 of x to 1

x & 1 is used to test if bit 0 of x is 1 or 0

SDK represents to software development kit, and IDE represents to integrated development environment. The IDE is the software or the program is used to write, compile, run, and debug such as Xcode. The SDK is the underlying engine of the IDE, includes all the platform's libraries an app needs to access. It's more basic than an IDE because it doesn't usually have graphical tools.

It may work with any character from the HTML Escape character list, but I had the same problem with a Java project. I used StringEscapeUtils.escapeHTML("Testing \" <br> <p>") and the title was <a href=".." title="Test&quot; &lt;br&gt; &lt;p&gt;">Testing</a>.

It only worked for me when I changed the StringEscapeUtils to StringEscapeUtils.escapeJavascript("Testing \" <br> <p>") and it worked in every browser.

Suppose you have a function that returns a substantial object:

Matrix multiply(const Matrix &a, const Matrix &b);

When you write code like this:

Matrix r = multiply(a, b);

then an ordinary C++ compiler will create a temporary object for the result of multiply(), call the copy constructor to initialise r, and then destruct the temporary return value. Move semantics in C++0x allow the "move constructor" to be called to initialise r by copying its contents, and then discard the temporary value without having to destruct it.

This is especially important if (like perhaps the Matrix example above), the object being copied allocates extra memory on the heap to store its internal representation. A copy constructor would have to either make a full copy of the internal representation, or use reference counting and copy-on-write semantics interally. A move constructor would leave the heap memory alone and just copy the pointer inside the Matrix object.

It seems like Github has changed their layout since you posted this question. I just created a repository and it used to give you instructions on screen. It appears they have changed that approach.

Here is the information they used to give on repo creation:

Use an AppDomain

It is safer and more flexible to load the assembly into its own AppDomain first.

So instead of the answer given previously:

var asm = Assembly.LoadFile(@"C:\myDll.dll");
var type = asm.GetType("TestRunner");
var runnable = Activator.CreateInstance(type) as IRunnable;
if (runnable == null) throw new Exception("broke");
runnable.Run();

I would suggest the following (adapted from this answer to a related question):

var domain = AppDomain.CreateDomain("NewDomainName");
var t = typeof(TypeIWantToLoad);
var runnable = domain.CreateInstanceFromAndUnwrap(@"C:\myDll.dll", t.Name) as IRunnable;
if (runnable == null) throw new Exception("broke");
runnable.Run();

Now you can unload the assembly and have different security settings.

If you want even more flexibility and power for dynamic loading and unloading of assemblies, you should look at the Managed Add-ins Framework (i.e. the System.AddIn namespace). For more information, see this article on Add-ins and Extensibility on MSDN.

Basically unmanaged code is code which does not run under the .NET CLR (aka not VB.NET, C#, etc.). My guess is that NUnit has a runner/wrapper which is not .NET code (aka C++).

React is not passing you the kind of events you might think. Rather, it is passing synthetic events.

In a brief test, event.keyCode == 0 is always true. What you want is event.charCode

Sorry, should have asked for your css as well. As is, basically what you need to look at is giving your container div the style .container { width: 100%; } in your css and then the enclosed divs will inherit this as long as you don't give them their own width. You were also missing a few closing tags, and the </center> closes a <center> without it ever being open, at least in this section of code. I wasn't sure if you wanted the image in the same div that contains your content or separate, so I created two examples. I changed the width of the img to 100px simply because jsfiddle offers a small viewing area. Let me know if it's not what you're looking for.

content and image separate: http://jsfiddle.net/QvqKS/2/

content and image in same div (img floated left): http://jsfiddle.net/QvqKS/3/

My solution (vb.net):

Private Function ConvertToBoolean(p1 As Object) As Boolean
    If p1 Is Nothing Then Return False
    If IsDBNull(p1) Then Return False
    If p1.ToString = "1" Then Return True
    If p1.ToString.ToLower = "true" Then Return True
    Return False
End Function

    var X = 0.0;
    var Y = 0.0;
    var Z = 0.0;

    for(i = 0; i < data.length; i++){
        var lat = data[i][0] * Math.PI / 180;
        var lon = data[i][1] * Math.PI / 180;

        var b = Math.cos(lat) * Math.sin(lon);
        var c = Math.sin(lat);

        X += a;
        Y += b;
        Z += c;
    }

    X /= num_coords;
    Y /= num_coords;
    Z /= num_coords;

    var lon = Math.atan2(Y, X);
    var hyp = Math.sqrt(X * X + Y * Y);
    var lat = Math.atan2(Z, hyp);

    var newY = (lon * 180 / Math.PI);

I am not an expert, but this is what I know:

1. Function is C language term, it refers to a piece of code and the function name will be the identifier to use this function.

2. Method is the OO term, typically it has a this pointer in the function parameter. You can not invoke this piece of code like C, you need to use object to invoke it.

3. The invoke methods are also different. Here invoke meaning to find the address of this piece of code. C/C++, the linking time will use the function symbol to locate.

4. Objecive-C is different. Invoke meaning a C function to use data structure to find the address. It means everything is known at run time.

The non-recursive version of the function is not too hard - here it is for integers:

long powi(long x, unsigned n)
{
    long p = x;
    long r = 1;

    while (n > 0)
    {
        if (n % 2 == 1)
            r *= p;
        p *= p;
        n /= 2;
    }

    return(r);
}

(Hacked out of code for raising a double value to an integer power - had to remove the code to deal with reciprocals, for example.)

Using flexbox:

HTML:

<div class="wrapper">
    <img src="pikachu.gif"/>
</div>

CSS:

.wrapper {
    height: 300px;
    width: 300px;
    display: flex;
    align-items: flex-end;
}

As requested in some comments on another answer, the image can also be horizontally centred with justify-content: center;

Tomalak's answer worked great for me (+1)

I only needed to make alter it slightly for my purposes, and I didn't need a password - it's for corporate domain:

Option Explicit
Dim l: l = "Z:"
Dim s: s = "\\10.10.10.1\share"
Dim Network: Set Network = CreateObject("WScript.Network")
Dim CheckDrive: Set CheckDrive = Network.EnumNetworkDrives()
Dim DriveExists: DriveExists = False
Dim i

For i = 0 to CheckDrive.Count - 1
  If CheckDrive.Item(i) = l Then
    DriveExists = True
  End If
Next

If DriveExists = False Then
  Network.MapNetworkDrive l, s, False
Else
  MsgBox l + " Drive already mapped"
End If

Or if you want to disconnect the drive:

For i = 0 to CheckDrive.Count - 1
  If CheckDrive.Item(i) = l Then 
    WshNetwork.RemoveNetworkDrive CheckDrive.Item(i)
  End If
Next

Angular routing : Manual navigation

First you need to import the angular router :

import {Router} from "@angular/router"

Then inject it in your component constructor :

constructor(private router: Router) { }

And finally call the .navigate method anywhere you need to "redirect" :

this.router.navigate(['/your-path'])

You can also put some parameters on your route, like user/5 :

this.router.navigate(['/user', 5])

use this and it works on both the static arrays and dynamically generated arrays.

var array = [12,2,23,324,23,123,4,23,132,23];
var getMaxValue = Math.max.apply(Math, array );

I had the issue when I use trying to find max value from code below

$('#myTabs').find('li.active').prevAll().andSelf().each(function () {
            newGetWidthOfEachTab.push(parseInt($(this).outerWidth()));
        });

        for (var i = 0; i < newGetWidthOfEachTab.length; i++) {
            newWidthOfEachTabTotal += newGetWidthOfEachTab[i];
            newGetWidthOfEachTabArr.push(parseInt(newWidthOfEachTabTotal));
        }

        getMaxValue = Math.max.apply(Math, array);

I was getting 'NAN' when I use

    var max_value = Math.max(12, 21, 23, 2323, 23);

download the opencv 2.2 version from https://sourceforge.net/projects/opencvlibrary/files/opencv-win/

install package.

then Copy cv2.pyd to C:/Python27/lib/site-packeges.

and it should work:

import cv2

The simplest way:

td:nth-child(2) {
    padding-right: 20px;
}?

But that won't work if you need to work with background color or images in your table. In that case, here is a slightly more advanced solution (CSS3):

td:nth-child(2) {
    border-right: 10px solid transparent;
    -webkit-background-clip: padding;
    -moz-background-clip: padding;
    background-clip: padding-box;
}

It places a transparent border to the right of the cell and pulls the background color/image away from the border, creating the illusion of spacing between the cells.

Note: For this to work, the parent table must have border-collapse: separate. If you have to work with border-collapse: collapse then you have to apply the same border style to the next table cell, but on the left side, to accomplish the same results.

You can try something like this:

int val = Convert.ToInt32("" + '1');

Command Should be hadoop fs -du -s -h \dirPath

• -du [-s] [-h] ... : Show the amount of space, in bytes, used by the files that match the specified file pattern.

• -s : Rather than showing the size of each individual file that matches the
  pattern, shows the total (summary) size.

• -h : Formats the sizes of files in a human-readable fashion rather than a number of bytes. (Ex MB/GB/TB etc)

  Note that, even without the -s option, this only shows size summaries one level deep into a directory.

  The output is in the form size name(full path)

window.location sets the URL of your current window. To open a new window, you need to use window.open. This should work:

function ToKey(){
    var key = document.tokey.key.value.toLowerCase();
    if (key == "smk") {
        window.open('http://www.smkproduction.eu5.org', '_blank');
    } else {
        alert("Kodi nuk është valid!");
    }
}

Notice that this doesn't work in Windows.
The module pxssh does exactly what you want:
For example, to run 'ls -l' and to print the output, you need to do something like that :

from pexpect import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.sendline ('ls -l')
    s.prompt()         # match the prompt
    print s.before     # print everything before the prompt.
    s.logout()

In my case reload() doesn't work because the asp.net controls behavior. So, to solve this issue I've used this approach, despite seems a work around.

self.clear = function () {
    //location.reload(true); Doesn't work to IE neither Firefox;
    //also, hash tags must be removed or no postback will occur.
    window.location.href = window.location.href.replace(/#.*$/, '');
};

int index = dt.Rows.IndexOf(row);

But you're probably better off using a for loop instead of foreach.

Webdriver doesn't contain an API to do it. See issue 141 from Selenium tracker for more info. The title of the issue says that it's about response headers but it was decided that Selenium won't contain API for request headers in scope of this issue. Several issues about adding API to set request headers have been marked as duplicates: first, second, third.

Here are a couple of possibilities that I can propose:

1. Use another driver/library instead of selenium
2. Write a browser-specific plugin (or find an existing one) that allows you to add header for request.
3. Use browsermob-proxy or some other proxy.

I'd go with option 3 in most of cases. It's not hard.

Note that Ghostdriver has an API for it but it's not supported by other drivers.

They are access modifiers and help us implement Encapsulation (or information hiding). They tell the compiler which other classes should have access to the field or method being defined.

protected - Only the current class and subclasses (and sometimes also same-package classes) of this class will have access to the field or method.

public - Any class can refer to the field or call the method.

This assumes these keywords are used as part of a field or method declaration within a class definition.

General purpose normalisation function to format any timestamp from any timezone to other. Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')

/**
 * Convert Datetime from any given olsonzone to other.
 * @return datetime in user specified format
 */

function datetimeconv($datetime, $from, $to)
{
    try {
        if ($from['localeFormat'] != 'Y-m-d H:i:s') {
            $datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
        }
        $datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
        $datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
        return $datetime->format($to['localeFormat']);
    } catch (\Exception $e) {
        return null;
    }
}

Usage:

$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta'];

$to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC'];

datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"

I find the adding <br> does what is wanted.

A good reference for finding any symbol in LaTeX is http://detexify.kirelabs.org/classify.html - just draw what you want to find, and it will show you a list of potential symbols.

You need to use css-loader when creating bundle with webpack.

Install it:

npm install css-loader --save-dev

And add it to loaders in your webpack configs:

module.exports = {
  module: {
    loaders: [
      { test: /\.css$/, loader: "style-loader!css-loader" },
      // ...
    ]
  }
};

After this, you will be able to include css files in js.

You can use this extension method.

public static class StreamExtensions
{
    public static byte[] ToByteArray(this Stream stream)
    {
        var bytes = new List<byte>();

        int b;
        while ((b = stream.ReadByte()) != -1)
            bytes.Add((byte)b);

        return bytes.ToArray();
    }
}

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)

1  4  5  6
2  7  8  9

import java.util.Scanner;
public class CapitolizeOneString {

    public static void main(String[] args)
    {
        Scanner  scan = new Scanner(System.in);
        System.out.print(" Please enter Your word      = ");
        String str=scan.nextLine();

        printCapitalized( str );
    }  // end main()

    static void printCapitalized( String str ) {
        // Print a copy of str to standard output, with the
        // first letter of each word in upper case.
        char ch;       // One of the characters in str.
        char prevCh;   // The character that comes before ch in the string.
        int i;         // A position in str, from 0 to str.length()-1.
        prevCh = '.';  // Prime the loop with any non-letter character.
        for ( i = 0;  i < str.length();  i++ ) {
            ch = str.charAt(i);
            if ( Character.isLetter(ch)  &&  ! Character.isLetter(prevCh) )
                System.out.print( Character.toUpperCase(ch) );
            else
                System.out.print( ch );
            prevCh = ch;  // prevCh for next iteration is ch.
        }
        System.out.println();
    }   
}  // end class

Look at the google gson library. It provides a rich api for dealing with this and is very straightforward to use.

Take a look at Generic Lists.

The pure javascript selectedIndex attribute is the right way to go because,it's pure javascript and works cross-browser:

$('#selectBox')[0].selectedIndex=4;

Here is a jsfiddle demo with two dropdowns using one to set the other:

<select onchange="$('#selectBox')[0].selectedIndex=this.selectedIndex">
  <option>0</option>
  <option>1</option>
  <option>2</option>
</select>

<select id="selectBox">
  <option value="0">Number 0</option>
  <option value="1">Number 1</option>
  <option value="2">Number 2</option>
</select>

You can also call this before changing the selectedIndex if what you want is the "selected" attribute on the option tag (here is the fiddle):

$('#selectBox option').removeAttr('selected')
   .eq(this.selectedIndex).attr('selected','selected');

_{Note: This is not a duplicate, because the OP is aware that the image from cv2.imread is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)}

To illustrate, I've opened up this same color JPEG image:

once using the conversion

img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

and another by loading it in gray scale mode

img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom

I've summed up the diff too to see

import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image

I tried all cv2.imread() modes

Among all the IMREAD_ modes for cv2.imread(), only IMREAD_COLOR and IMREAD_ANYCOLOR can be converted using COLOR_BGR2GRAY, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE

The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)

Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.

In brief, let's not mix the versions and types in the processing pipeline.

So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Update: a better idea, set the "AppendDataBoundItems" property to true, then declare the "Choose item" declaratively. The databinding operation will add to the statically declared item.

<asp:DropDownList ID="ddl" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="Please choose..."></asp:ListItem>
</asp:DropDownList>

If you also want it to be a command you can reference without remembering the arguments, you could simply alias it:

alias df-gb='df -BG'

So if you type:

df-gb

into a terminal, you'll get your intended output of the disk usage in GB.

EDIT: or even use just df -h to get it in a standard, human readable format.

A more thorough solution

The core of this is the replace call. So far, I don't think any of the proposed solutions handle all of the following cases:

• Integers: 1000 => '1,000'
• Strings: '1000' => '1,000'
• For strings:
  • Preserves zeros after decimal: 10000.00 => '10,000.00'
  • Discards leading zeros before decimal: '01000.00 => '1,000.00'
  • Does not add commas after decimal: '1000.00000' => '1,000.00000'
  • Preserves leading - or +: '-1000.0000' => '-1,000.000'
  • Returns, unmodified, strings containing non-digits: '1000k' => '1000k'

The following function does all of the above.

addCommas = function(input){
  // If the regex doesn't match, `replace` returns the string unmodified
  return (input.toString()).replace(
    // Each parentheses group (or 'capture') in this regex becomes an argument 
    // to the function; in this case, every argument after 'match'
    /^([-+]?)(0?)(\d+)(.?)(\d+)$/g, function(match, sign, zeros, before, decimal, after) {

      // Less obtrusive than adding 'reverse' method on all strings
      var reverseString = function(string) { return string.split('').reverse().join(''); };

      // Insert commas every three characters from the right
      var insertCommas  = function(string) { 

        // Reverse, because it's easier to do things from the left
        var reversed           = reverseString(string);

        // Add commas every three characters
        var reversedWithCommas = reversed.match(/.{1,3}/g).join(',');

        // Reverse again (back to normal)
        return reverseString(reversedWithCommas);
      };

      // If there was no decimal, the last capture grabs the final digit, so
      // we have to put it back together with the 'before' substring
      return sign + (decimal ? insertCommas(before) + decimal + after : insertCommas(before + after));
    }
  );
};

You could use it in a jQuery plugin like this:

$.fn.addCommas = function() {
  $(this).each(function(){
    $(this).text(addCommas($(this).text()));
  });
};

Here is the simplest way to do this

static void Main(string[] args)
{
    Task t = MainAsync(args);
    t.Wait();
}

static async Task MainAsync(string[] args)
{
    await ...
}

Try using scrollTo method More Info

Don't put a name for target window when you use window.open("","NAME",....)

If you do it you can only open it once. Use _blank, etc instead of.

I'm "old school" I define efficiency in lowest latency, processor time and memory usage, our nemesis are the bloated libraries. So there is exactly one right way:

    def rotatel(nums):
        back = nums.pop(0)
        nums.append(back)
        return nums

var charCount = "string with periods...".Count(x => '.' == x);

This will handle paths with spaces:

find ./ -type f -name "*.php" -o -name "*.html" -exec tar uvf myarchives.tar {} +

You should use TryParse method which Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the conversion succeeded.

    int intParsed;
    if(int.TryParse(txtMyText.Text.Trim(),out intParsed))
    {
        // perform your code
    }

For the specific question of generating a reverse IntStream, try something like this:

static IntStream revRange(int from, int to) {
    return IntStream.range(from, to)
                    .map(i -> to - i + from - 1);
}

This avoids boxing and sorting.

For the general question of how to reverse a stream of any type, I don't know of there's a "proper" way. There are a couple ways I can think of. Both end up storing the stream elements. I don't know of a way to reverse a stream without storing the elements.

This first way stores the elements into an array and reads them out to a stream in reverse order. Note that since we don't know the runtime type of the stream elements, we can't type the array properly, requiring an unchecked cast.

@SuppressWarnings("unchecked")
static <T> Stream<T> reverse(Stream<T> input) {
    Object[] temp = input.toArray();
    return (Stream<T>) IntStream.range(0, temp.length)
                                .mapToObj(i -> temp[temp.length - i - 1]);
}

Another technique uses collectors to accumulate the items into a reversed list. This does lots of insertions at the front of ArrayList objects, so there's lots of copying going on.

Stream<T> input = ... ;
List<T> output =
    input.collect(ArrayList::new,
                  (list, e) -> list.add(0, e),
                  (list1, list2) -> list1.addAll(0, list2));

It's probably possible to write a much more efficient reversing collector using some kind of customized data structure.

UPDATE 2016-01-29

Since this question has gotten a bit of attention recently, I figure I should update my answer to solve the problem with inserting at the front of ArrayList. This will be horribly inefficient with a large number of elements, requiring O(N^2) copying.

It's preferable to use an ArrayDeque instead, which efficiently supports insertion at the front. A small wrinkle is that we can't use the three-arg form of Stream.collect(); it requires the contents of the second arg be merged into the first arg, and there's no "add-all-at-front" bulk operation on Deque. Instead, we use addAll() to append the contents of the first arg to the end of the second, and then we return the second. This requires using the Collector.of() factory method.

The complete code is this:

Deque<String> output =
    input.collect(Collector.of(
        ArrayDeque::new,
        (deq, t) -> deq.addFirst(t),
        (d1, d2) -> { d2.addAll(d1); return d2; }));

The result is a Deque instead of a List, but that shouldn't be much of an issue, as it can easily be iterated or streamed in the now-reversed order.

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))
#      x y
# 2 G459 2

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

I used this FileSaver.js. In my case with csv files, i did this (in coffescript):

  $.ajax
    url: "url-to-server"
    data: "data-to-send"
    success: (csvData)->
      blob = new Blob([csvData], { type: 'text/csv' })
      saveAs(blob, "filename.csv")

I think for most complicated case, the data must be processed properly. Under the hood FileSaver.js implement the same approach of the answer of Jonathan Amend.

Below are provided steps to fix your issue.

1. Open your IIS
2. Go to "Sites" option.

use bytea (or Large Objects if you absolutely have to)

Try this one,

var timestamp = firebase.firestore.FieldValue.serverTimestamp()
var timestamp2 = new Date(timestamp.toDate()).toUTCString()

Like this :

var id = $('div.foo').attr('id');

1. get actual ID
2. put actuel ID and add the new one

There is another point must be noted before regenerating keys that resolve 90% issue.

for example your xampp directory is C:\xampp

and htdocs folder is C:\xampp\htdocs

we want to open page called: example-cap.html and page is showing error "invalid domain for site key"

USE YOUR LOCALHOST ADDRESS in browser address like:

localhost/example-cap.html

this will resolve your issue

DONOT USE ADDRESS c:\xampp\htdocs\example-cap.html this will generate error

The isdigit method of the str type returns True iff the given string is nothing but one or more digits. If it's not, you know the string should be treated as just a string.

An ftl file could just have a series of html tags just as a JSP page or it can have freemarker template coding for representing the objects passed on from a controller java file.
But, its actual ability is to combine the contents of a java class and view/client side stuff(html/ JQuery/ javascript etc). It is quite similar to velocity. You could map a method or object of a class to a freemarker (.ftl) page and use it as if it is a variable or a functionality created in the very page.

Now I see what you are doing. You cannot send output to the screen then change the headers. If you are trying to create an XML file of map marker and download them to display, they should be in separate files.

Take this

<?php
require("database.php");
function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','&lt;',$htmlStr);
$xmlStr=str_replace('>','&gt;',$xmlStr);
$xmlStr=str_replace('"','&quot;',$xmlStr);
$xmlStr=str_replace("'",'&#39;',$xmlStr);
$xmlStr=str_replace("&",'&amp;',$xmlStr);
return $xmlStr;
}
// Opens a connection to a MySQL server
$connection=mysql_connect (localhost, $username, $password);
if (!$connection) {
  die('Not connected : ' . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
  die('Invalid query: ' . mysql_error());
}
header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';
// Iterate through the rows, printing XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  echo '<marker ';
  echo 'name="' . parseToXML($row['name']) . '" ';
  echo 'address="' . parseToXML($row['address']) . '" ';
  echo 'lat="' . $row['lat'] . '" ';
  echo 'lng="' . $row['lng'] . '" ';
  echo 'type="' . $row['type'] . '" ';
  echo '/>';
}
// End XML file
echo '</markers>';
?>

and place it in phpsqlajax_genxml.php so your javascript can download the XML file. You are trying to do too many things in the same file.

The best solution (works and is short) for me is:

    $(document).on('input', 'textarea', function () {
        $(this).outerHeight(38).outerHeight(this.scrollHeight); // 38 or '1em' -min-height
    }); 

It works like a charm without any blinking with paste (with mouse also), cut, entering and it shrinks to the right size.

Please take a look at jsFiddle.

python -c "import xml.etree.ElementTree as ET; \
  print(ET.parse(open('pom.xml')).getroot().find( \
  '{http://maven.apache.org/POM/4.0.0}version').text)"

As long as you have python 2.5 or greater, this should work. If you have a lower version than that, install python-lxml and change the import to lxml.etree. This method is quick and doesn't require downloading any extra plugins. It also works on malformed pom.xml files that don't validate with xmllint, like the ones I need to parse. Tested on Mac and Linux.

About int() and Swift 2.x: if you get a nil value after conversion check if you try to convert a string with a big number (for example: 1073741824), in this case try:

let bytesInternet : Int64 = Int64(bytesInternetString)!

Me, I'd do ('%f' % x).rstrip('0').rstrip('.') -- guarantees fixed-point formatting rather than scientific notation, etc etc. Yeah, not as slick and elegant as %g, but, it works (and I don't know how to force %g to never use scientific notation;-).

In addition to the above answers, there is always the scorched earth method.

rm -R <folder>

in Windows shell the command is:

rd /s <folder>

Then you can just checkout the project again:

git clone -v <repository URL> 

This will definitely remove any local changes and pull the latest from the remote repository. Be careful with rm -R as it will delete your good data if you put the wrong path. For instance, definitely do not do:

rm -R /

edit: To fix spelling and add emphasis.

Here's a function that is also based on cloneNode, but with an option to clone only the parent node and move all the children (to preserve their event listeners):

function recreateNode(el, withChildren) {
  if (withChildren) {
    el.parentNode.replaceChild(el.cloneNode(true), el);
  }
  else {
    var newEl = el.cloneNode(false);
    while (el.hasChildNodes()) newEl.appendChild(el.firstChild);
    el.parentNode.replaceChild(newEl, el);
  }
}

Remove event listeners on one element:

recreateNode(document.getElementById("btn"));

Remove event listeners on an element and all of its children:

recreateNode(document.getElementById("list"), true);

If you need to keep the object itself and therefore can't use cloneNode, then you have to wrap the addEventListener function and track the listener list by yourself, like in this answer.

Try the maven-exec-plugin. From there:

mvn exec:java -Dexec.mainClass="com.example.Main"

This will run your class in the JVM. You can use -Dexec.args="arg0 arg1" to pass arguments.

If you're on Windows, apply quotes for exec.mainClass and exec.args:

mvn exec:java -D"exec.mainClass"="com.example.Main"

If you're doing this regularly, you can add the parameters into the pom.xml as well:

$elapsed = '2592000';
// Time in the past
$time_past = '2014-07-16 11:35:33';
$time_past = strtotime($time_past);

// Add a month to that time
$time_past = $time_past + $elapsed;

// Time NOW
$time_now = time();

// Check if its been a month since time past
if($time_past > $time_now){
    echo 'Hasnt been a month';    
}else{
    echo 'Been longer than a month';
}

If it is safe to assume only one set of spaces in column two (which is the original example):

awk '{print $1$2}' /tmp/input.txt

Adding another field, e.g. awk '{print $1$2$3}' /tmp/input.txt will catch two sets of spaces (up to three words in column two), and won't break if there are fewer.

If you have an indeterminate (large) number of space delimited words, I'd use one of the previous suggestions, otherwise this solution is the easiest you'll find using awk.

I would start by turning off TCP offloading. There have been a few things that cause intermittent connectivity issues and this is the one that is usually the culprit.

The ::after pseudo-element rocks :)

If you play a bit you can even set your resized border element to appear centered or to appear only if there is another element next to it (like in menus). Here is an example with a menu:

    padding: 0 10px;
}

#menu > ul > li + li::after {
    content:"";

    height: 50%;
    width: 1px;
}

#menu > ul > li {
  position: relative;
  float: left;
  padding: 0 10px;
  list-style: none;
}
#menu > ul > li + li::after {
  content: "";

         }

         System.IO.File.Copy(DllName, @destinationfilename);
     }
        // use dll-> XSD
     var returnVal = await DoProcess(
            @helperRoot + "xsd.exe", "\"" + @destinationfilename + "\"");

     destinationfilename = destinationfilename.Replace(".dll", ".xsd");

     if (System.IO.File.Exists(@destinationfilename))
     {
          // now use XSD
          returnVal =
            await DoProcess(
              @helperRoot + "xsd.exe", "/c /namespace:RuleBook /language:CS " + "\"" + @destinationfilename + "\"");

            if (System.IO.File.Exists(@destinationfilename.Replace(".xsd", ".cs")))
            {
                string getXSD = System.IO.File.ReadAllText(@destinationfilename.Replace(".xsd", ".cs"));
           
            }
        }
}

In the adapter you can set the first item as disabled. Below is the sample code

@Override
public boolean isEnabled(int position) {
    if (position == 0) {
        // Disable the first item from Spinner
        // First item will be use for hint
        return false;
    } else {
        return true;
    }
}

And set the first item to grey color.

@Override
public View getDropDownView(int position, View convertView,
                                    ViewGroup parent) {
    View view = super.getDropDownView(position, convertView, parent);
    TextView tv = (TextView) view;
    if (position == 0) {
        // Set the hint text color gray
        tv.setTextColor(Color.GRAY);
    } else {
        tv.setTextColor(Color.BLACK);
    }
    return view;
}

And if the user selects the first item then do nothing.

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    String selectedItemText = (String) parent.getItemAtPosition(position);
    // If user change the default selection
    // First item is disable and it is used for hint
    if (position > 0) {
        // Notify the selected item text
        Toast.makeText(getApplicationContext(), "Selected : " + selectedItemText, Toast.LENGTH_SHORT).show();
    }
}

How to add a hint to Spinner in Android

Quick & dirty:

function getObjName(obj) {
  return (wrap={obj}) && eval('for(p in obj){p}') && (wrap=null);
}

3 files have to changed appsettings.json (see the last section - kestrel ), launchsettings.json - applicationurl commented out, and a 2 lines change in Startup.cs

Add below code in appsettings.json file and port to any as you wish.

  },

 "Kestrel": {

   "Endpoints": {

     "Http": {

       "Url": "http://localhost:5003"

     }

   }

 }

 }

Modify Startup.cs with below lines.

using Microsoft.AspNetCore.Server.Kestrel.Core;

services.Configure<KestrelServerOptions>(Configuration.GetSection("Kestrel"));

You need to convert Array to string :

//arrayOfValues = [1, 2, 3];  
$.get('/controller/MyAction', { arrayOfValues: "1, 2, 3" }, function (data) {...

this works even in form of int, long or string

public ActionResult MyAction(int[] arrayOfValues )

For anyone who may stumble across this old question ...

There is one thing that I think needs to be addressed.

~/.nanorc is used to apply your user specific settings to nano, so if you are editing files that require the use of sudo nano for permissions then this is not going to work.

When using sudo your custom user configuration files will not be loaded when opening a program, as you are not running the program from your account so none of your configuration changes in ~/.nanorc will be applied.

If this is the situation you find yourself in (wanting to run sudo nano and use your own config settings) then you have three options :

• using command line flags when running sudo nano
• editing the /root/.nanorc file
• editing the /etc/nanorc global config file

Keep in mind that /etc/nanorc is a global configuration file and as such it affects all users, which may or may not be a problem depending on whether you have a multi-user system.

Also, user config files will override the global one, so if you were to edit /etc/nanorc and ~/.nanorc with different settings, when you run nano it will load the settings from ~/.nanorc but if you run sudo nano then it will load the settings from /etc/nanorc.

Same goes for /root/.nanorc this will override /etc/nanorc when running sudo nano

Using flags is probably the best option unless you have a lot of options.

select * 
from emp 
where rownum <= &upperlimit 
minus 
select * 
from emp 
where rownum <= &lower limit ;

Try this example

CREATE PROCEDURE MyProc
BEGIN
    --Stored Procedure variables
    Declare @maxOr int; 
    Declare @maxCa int; 

    --Getting query result in the variable (first variant of syntax)
    SET @maxOr = (SELECT MAX(orId) FROM [order]); 

    --Another variant of seting variable from query
    SELECT @maxCa=MAX(caId) FROM [cart]; 

    --Updating record through the variable
    INSERT INTO [order_cart] (orId,caId)
    VALUES(@maxOr, @maxCa); 

    --return values to the program as dataset
    SELECT
       @maxOr AS maxOr,
       @maxCa AS maxCa

    -- return one int value as "return value"
    RETURN @maxOr
END
GO

The <=> ("Spaceship") operator will offer combined comparison in that it will :

Return 0 if values on either side are equal
Return 1 if the value on the left is greater
Return -1 if the value on the right is greater

The rules used by the combined comparison operator are the same as the currently used comparison operators by PHP viz. <, <=, ==, >= and >. Those who are from Perl or Ruby programming background may already be familiar with this new operator proposed for PHP7.

   //Comparing Integers

    echo 1 <=> 1; //output  0
    echo 3 <=> 4; //output -1
    echo 4 <=> 3; //output  1

    //String Comparison

    echo "x" <=> "x"; //output  0
    echo "x" <=> "y"; //output -1
    echo "y" <=> "x"; //output  1

SQL Server 2012 version above,

SELECT  format(Closing_Date,'yyyy-MM') as ClosingMonth,
        Category,  
        COUNT(Status) TotalCount 
FROM    MyTable
WHERE   Closing_Date >= '2012-02-01' 
AND     Closing_Date <= '2012-12-31'
AND     Defect_Status1 IS NOT NULL
GROUP BY format(Closing_Date,'yyyy-MM'), Category;

Most of the time your background color is different from the background of your table. Since there are spaces between the cells, those spaces will create the illusion of lines with the color of the background behind the table.

The solution is to get rid of those spaces.

Inside the table tag write:

cellspacing="0"

you can use command

date | awk '{print $4}'| cut -d ':' -f3

as you mentioned using only the date|awk '{print $4}' pipeline gives you something like this

20:18:19

so as we can see if we want to extract some part of this string then we need a delimiter , for our case it is :, so we decide to chop on the basis of :. Now this delimiter will chop the string into three parts i.e. 20 ,18 and 19 , as we want the second one we use -f2 in our command. to sum up ,

cut : chops some string based on delimeter.

-d : delimeter (here :)

-f2 : the chopped off token that we want.

You can use this:

$("#id").click(function()
{
   $(this).data('clicked', true);
});

Now check it via an if statement:

if($("#id").data('clicked'))
{
   // code here 
}

For more information you can visit the jQuery website on the .data() function.

It is the $sce service that blocks URLs with external domains, it is a service that provides Strict Contextual Escaping services to AngularJS, to prevent security vulnerabilities such as XSS, clickjacking, etc. it's enabled by default in Angular 1.2.

You can disable it completely, but it's not recommended

angular.module('myAppWithSceDisabledmyApp', [])
   .config(function($sceProvider) {
       $sceProvider.enabled(false);
   });

I am using Windows 7 with Docker Toolbox and to fix it just open Docker Quickstart Terminal.

$ docker version Client: Version: 17.05.0-ce API version: 1.29 Go version: go1.7.5 Git commit: 89658be Built: Fri May 5 15:36:11 2017 OS/Arch: windows/amd64

You can also write these lines of code in the direct parent layout of the .xml layout file in which you have the "problem":

android:focusable="true"
android:focusableInTouchMode="true"

For example:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    ...
    android:focusable="true"
    android:focusableInTouchMode="true" >

    <EditText
        android:id="@+id/myEditText"
        ...
        android:hint="@string/write_here" />

    <Button
        android:id="@+id/button_ok"
        ...
        android:text="@string/ok" />
</LinearLayout>

EDIT :

Example if the EditText is contained in another layout:

<?xml version="1.0" encoding="utf-8"?>
<ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    ... >                                            <!--not here-->

    ...    <!--other elements-->

    <LinearLayout
        android:id="@+id/theDirectParent"
        ...
        android:focusable="true"
        android:focusableInTouchMode="true" >        <!--here-->

        <EditText
            android:id="@+id/myEditText"
            ...
            android:hint="@string/write_here" />

        <Button
            android:id="@+id/button_ok"
            ...
            android:text="@string/ok" />
    </LinearLayout>

</ConstraintLayout>

The key is to make sure that the EditText is not directly focusable.
Bye! ;-)

There appear to be several ways to launch the SDK Manager:

1. SDK Manager.exe in the root of the Android SDK.
2. SDK Manager.exe in sdk\tools\lib of the Android SDK.
3. Window -> Android SDK Manager menu in Eclipse
4. android.bat in sdk\tools of the Android SDK.

In my case, it looks like android.bat fails on the line:

for /f %%a in ('%java_exe% -jar lib\archquery.jar') do set swt_path=lib\%%a

As far as what that line is doing... if I manually run: "[path_to_java]java" -jar lib\archquery.jar

It successfully returns: x86_64

But when the batch file runs that same command, I don't know why but it fails with the error message:

Unable to access jarfile lib\archquery.jar

So the variable swt_path gets set to an empty string. Everything breaks down from there.

The batch file sets the correct value for the variable java_exe. Others have commonly reported this as a problem, but those workarounds weren't relevant in my case.

People have recommended commenting out the problem line by adding REM to the beginning of it, and adding a line to manually set the swt_path variable, which is a valid workaround:

REM for /f %%a in ('%java_exe% -jar lib\archquery.jar') do set swt_path=lib\%%a
set swt_path=lib\x86

BUT, the critical issue in my case is that it's choosing to load a jar file from either the lib\x86 or the lib\x86_64 folder here. At some point, things were getting confused between the BAT file error, a 32-bit JDK, and a 64-bit Android SDK.

SO, the workaround in my case was to:

1. Uninstall ALL versions of Java
2. Install the JDK
   • You can either use the 32-bit Android SDK and install the 32-bit JDK
   • Or use the 64-bit Android SDK and install the 64-bit JDK
   • But the "bitness" of the JDK should match the Android SDK. It appears that either of the 32-bit or the 64-bit will work on a 64-bit computer, AS LONG AS the JDK bitness matches the Android SDK bitness.

3. Edit "android.bat"

   • If using the 32-bit Android SDK/JDK, use lib\x86:

     REM for /f %%a in ('%java_exe% -jar lib\archquery.jar') do set swt_path=lib\%%a
     set swt_path=lib\x86
     

   • If using the 64-bit Android SDK/JDK, use lib\x86_64:

     REM for /f %%a in ('%java_exe% -jar lib\archquery.jar') do set swt_path=lib\%%a
     set swt_path=lib\x86_64
     

After doing this, I can successfully run the SDK Manager by running android.bat, or from the Eclipse menu (but still not by running either of the SDK Manager.exe files directly).

First of all, thanks for guiding me and closing this issue. I found a way to fix this issue from your discussions. Yeah, Let's come to the point. The thing is I'm Using GoogleMapHelper v3 helper in CakePHP3. When i tried to open bootstrap modal popup, I got struck with the grey box issue over the map. It's been extended for 2 days. Finally i got a fix over this.

We need to Update the GoogleMapHelper to fix the issue

Need to add the below script in setCenterMap function

google.maps.event.trigger({$id}, \"resize\");

And need the include below code in JavaScript

google.maps.event.addListenerOnce({$id}, 'idle', function(){
   setCenterMap(new google.maps.LatLng({$this->defaultLatitude}, 
   {$this->defaultLongitude}));
});

In this case, the name of the selector is wrong. The colon here is part of the method signature; it means that the method takes one argument. I believe that you want

SEL sel = @selector(lowercaseString);

I've read all the answers, the answers of similar questions and the complexity of the most "good" solutions didn't satisfy me. I don't want to put a huge round function set, or a small one but fails on scientific notation. So, I came up with this function. It may help someone in my situation:

function round(num, dec) {
   const [sv, ev] = num.toString().split('e');
   return Number(Number(Math.round(parseFloat(sv + 'e' + dec)) + 'e-' + dec) + 'e' + (ev || 0));
}

I didn't run any performance test because I will call this just to update the UI of my application. The function gives the following results for a quick test:

// 1/3563143 = 2.806510993243886e-7
round(1/3563143, 2)  // returns `2.81e-7`

round(1.31645, 4)    // returns 1.3165

round(-17.3954, 2)   // returns -17.4

This is enough for me.

type C:\temp\test.bat>C:\temp\test.log

Mockito [3.4.0] can mock static methods!

1. Replace mockito-core dependency with mockito-inline:3.4.0.

2. Class with static method:

   class Buddy {
     static String name() {
       return "John";
     }
   }
   

3. Use new method Mockito.mockStatic():

   @Test
   void lookMomICanMockStaticMethods() {
     assertThat(Buddy.name()).isEqualTo("John");
   
     try (MockedStatic<Buddy> theMock = Mockito.mockStatic(Buddy.class)) {
       theMock.when(Buddy::name).thenReturn("Rafael");
       assertThat(Buddy.name()).isEqualTo("Rafael");
     }
   
     assertThat(Buddy.name()).isEqualTo("John");
   }
   

   Mockito replaces the static method within the try block only.

You are loading an entire HTML page into your div, including the html, head and body tags. What happens if you do the load and just have the opening script, closing script, and JavaScript code in the HTML that you load?

Here is the driver page:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

        <script type="text/javascript" src="http://www.google.com/jsapi"></script>
        <script type="text/javascript">
            google.load("jquery", "1.3.2");
        </script>
        <script type="text/javascript">
            $(document).ready(function(){
                $("#myButton").click(function() {
                    $("#myDiv").load("trackingCode.html");
                });
             });
         </script>
    </head>
    <body>
        <button id="myButton">Click Me</button>
        <div id="myDiv"></div>
    </body>
</html>

Here is the contents of trackingCode.html:

<script type="text/javascript">
    alert("Outside the jQuery ready");
    $(function() {
        alert("Inside the jQuery ready");
    });
 </script>

This works for me in Safari 4.

Update: Added DOCTYPE and html namespace to match the code on my test environment. Tested with Firefox 3.6.13 and example code works.

Bootstrap 3 has its own class for this called:

hidden-print

It is defined like this:

@media print {
  .hidden-print {
    display: none !important;
  }
}

You do not have to define it on your own.

In Bootstrap 4 this has changed to:

.d-print-none

Under the "Goto" menu, Control + M is Jump to Matching Bracket. Works for parentheses as well.
