before start make sure of installation:

yum install -y xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps

1. start xming or cygwin
2. make connection with X11 forwarding (in putty don't forget to set localhost:0.0 for X display location)
3. edit sshd.cong and restart

     cat /etc/ssh/sshd_config | grep X
                             X11Forwarding yes
                             X11DisplayOffset 10
AddressFamily inet

4. Without the X11 forwarding, you are subjected to the X11 SECURITY and then you must: authorize the remote server to make a connection with the local X Server using a method (for instance, the xhost command) set the display environment variable to redirect the output to the X server of your local computer. In this example: 192.168.2.223 is the IP of the server 192.168.2.2 is the IP of the local computer where the x server is installed. localhost can also be used.

blablaco@blablaco01 ~
$ xhost 192.168.2.223
192.168.2.223 being added to access control list

blablaco@blablaco01 ~
$ ssh -l root 192.168.2.223
[email protected] password:
Last login: Sat May 22 18:59:04 2010 from etcetc
[root@oel5u5 ~]# export DISPLAY=192.168.2.2:0.0
[root@oel5u5 ~]# echo $DISPLAY
192.168.2.2:0.0
[root@oel5u5 ~]# xclock&

Then the xclock application must launch.

Check it on putty or mobaxterm and don't check in remote desktop Manager software. Be careful for user that sudo in.

For me, the problem was that xorg-x11-xauth wasn't installed. I installed it and then it worked.

The packages that I have now are:

• libX11-common-1.6.3-2.el6.noarch
• libX11-1.6.3-2.el6.i686
• libX11-1.6.3-2.el6.x86_64
• xorg-x11-drv-ati-firware-7.6.1-2.el6.noarch
• xorg-x11-xauth-1.0.9-1.el6.x86_64

Yet another answer in case you already built the image:

1. invoke docker w/o sudo (How to fix docker: Got permission denied issue)

2. share the same USER & home & passwd between host and container share (tips: use user id instead of user name)

3. the dev folder for driver dependent libs to work well

4. plus X11 forward.

    docker run --name=CONTAINER_NAME --network=host --privileged \
      -v /dev:/dev \
      -v `echo ~`:/home/${USER} \
      -p 8080:80 \
      --user=`id -u ${USER}` \
      --env="DISPLAY" \
      --volume="/etc/group:/etc/group:ro" \
      --volume="/etc/passwd:/etc/passwd:ro" \
      --volume="/etc/shadow:/etc/shadow:ro" \
      --volume="/etc/sudoers.d:/etc/sudoers.d:ro" \
      --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" \
      -it REPO:TAG /bin/bash

you may ask, whats the point to use docker if so many things are the same? well, one reason I can think of is to overcome the package depency hell (https://en.wikipedia.org/wiki/Dependency_hell).

So this type of usage is more suitable for developer I think.

First off, Xvfb doesn't read configuration from xorg.conf. Xvfb is a variant of the KDrive X servers and like all members of that family gets its configuration from the command line.

It is true that XRandR and Xinerama are mutually exclusive, but in the case of Xvfb there's no Xinerama in the first place. You can enable the XRandR extension by starting Xvfb using at least the following command line options

Xvfb +extension RANDR [further options]

The D-Bus error can be fixed with dbus-launch :

dbus-launch command

you must enable X11 forwarding in you PuTTy

to do so open PuTTy, go to Connection => SSH => Tunnels and check mark the Enable X11 forwarding

Also sudo to server and export the below variable here IP is your local machine's IP

export DISPLAY=10.75.75.75:0.0

The way that X works is the same as the way any network program works. You have a server of some description (in this case, the X display server) which runs on a specific machine, and you have X clients (like firefox) that try to connect to that server to get their information displayed.

Often (on "home" machines), the client and server run on the same box and there's only one server, but X is powerful enough that this doesn't need to happen. It was built with the server/client separation built in from the start.

This allows you to do such wondrous things such as log on to your box (in text mode) halfway around the planet, tell it that the display server is the box you're currently on and, voila, the windows suddenly start appearing locally.

In order for a client to interact with a user, it needs to know how to find the server. There are a number of ways to do this. Many clients allow the -display or --displayoption to specify it:

xeyes -display paxbox1.paxco.com:0.0

Many will use the DISPLAY environment variable if a display isn't specifically given. You can set this variable like any other:

DISPLAY=paxbox1.paxco.com:0.0; export DISPLAY # in .profile
export DISPLAY=paxbox1.paxco.com:0.0 # in your shell
DISPLAY=paxbox1.paxco.com:0.0 firefox & # for that command (shell permitting)

The first part of the DISPLAY variable is just the address of the display server machine. It follows the same rule as any other IP address; it can be a resolvable DNS name (including localhost) or a specific IP address (such as 192.168.10.55).

The second part is X-specific. It gives the X "display" (X server) number and screen number to use. The first (display number) generally refers to a group of devices containing one or more screens but with a single keyboard and mouse (i.e., one input stream). The screen number generally gives the specific screen within that group.

An example would be:

+----------------------------------------+
|paxbox1.paxco.com|                      |
+-----------------+                      |
|                                        |
|  +----------+----+  +----------+----+  |
|  |Display :0|    |  |Display :1|    |  |
|  +----------+    |  +----------+    |  |
|  |               |  |               |  |
|  | +-----------+ |  |               |  |
|  | |Screen :0.0| |  |               |  |
|  | +-----------+ |  |               |  |
|  | +-----------+ |  |               |  |
|  | |Screen :0.1| |  |               |  |
|  | +-----------+ |  |               |  |

|  | |Screen :0.2| |  | |Screen :1.0| |  |

+----------------------------------------+

Here you have a single machine (paxbox1.paxco.com) with two display servers. The first has four screens and the second has two. The possibilities are then:

DISPLAY=paxbox1.paxco.com:0.0
DISPLAY=paxbox1.paxco.com:0.1
DISPLAY=paxbox1.paxco.com:0.2
DISPLAY=paxbox1.paxco.com:0.3
DISPLAY=paxbox1.paxco.com:1.0
DISPLAY=paxbox1.paxco.com:1.1

depending on where you want your actual windows to appear and which input devices you want to use.

The bash script solution:

if ! xset q &>/dev/null; then
    echo "No X server at \$DISPLAY [$DISPLAY]" >&2
    exit 1
fi

Doesn't work if you login from another console (Ctrl+Alt+F?) or ssh. For me this solution works in my Archlinux:

#!/bin/sh
ps aux|grep -v grep|grep "/usr/lib/Xorg"
EXITSTATUS=$?
if [ $EXITSTATUS -eq 0 ]; then
  echo "X server running"
  exit 1
fi

You can change /usr/lib/Xorg for only Xorg or the proper command on your system.

Don't know if you resolved this problem, but I have just resolved the same issue from the other side.

It appears Selenium and Firefox have difficulty talking to each other - I suspect Firefox 'evolve' changes over a number of releases, so backward and forward compatibility are not always guaranteed, and incompatibility always seems to generate the same error.

My problem started when I moved from FF 15 to FF 16. Running on Ubuntu, this happens auto magically along with other upgrades but I believe this was the critical change.

The problem was resolved by moving from Selenium 2.24.1 to Selenium 2.25.0

As the selenium change is just download the jar file and run it instead of the old one,it's worth trying this as a quick and easy troubleshooter - if it doesn't help, just switch back. In your case, I'm not sure which version of Selenium to try, but I think 2.24 should work with FF 10.

Another issue I have found in the past is that Firefox would not run as root on Ubuntu. This happens if Selenium is running as a service, or possibly if it is fired up from a bash script or cron job. This may explain why it runs for you but not for Jenkins.

Here is an SQL request to do that:

select column_name, count(1)
from table
group by column_name
having count (column_name) > 1;

I think a C++ DLL is a machine code file. Therefore decompiling will only result in assembler code. If you can read that and create C++ from that you're good to go.

setting pk to None is better, sinse Django can correctly create a pk for you

object_copy = MyObject.objects.get(pk=...)
object_copy.pk = None
object_copy.save()

This is what I do.

SELECT FullName
FROM
(
  SELECT LastName + ', ' + FirstName AS FullName
  FROM customers
) as sub
GROUP BY FullName

This technique applies in a straightforward way to your "edit" scenario:

SELECT FullName
FROM
(
  SELECT
     CASE
       WHEN LastName IS NULL THEN FirstName
       WHEN LastName IS NOT NULL THEN LastName + ', ' + FirstName
     END AS FullName
  FROM customers
) as sub
GROUP BY FullName

Use @RequestParam

@RequestMapping(value="user", method = RequestMethod.GET)
public @ResponseBody Item getItem(@RequestParam("data") String itemid){

    Item i = itemDao.findOne(itemid);              
    String itemName = i.getItemName();
    String price = i.getPrice();
    return i;
}

You want to do the following:

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS 
BEGIN
SET NOCOUNT ON;

    IF (UPDATE(QtyToRepair))
    BEGIN
        UPDATE SCHEDULE SET modified = GETDATE()
            , ModifiedUser = SUSER_NAME()
            , ModifiedHost = HOST_NAME()
        FROM SCHEDULE S
        INNER JOIN Inserted I ON S.OrderNo = I.OrderNo AND S.PartNumber = I.PartNumber
        WHERE S.QtyToRepair <> I.QtyToRepair
    END
END

Please note that this trigger will fire each time you update the column no matter if the value is the same or not.

You can switch to manual build so can control when this is done. Just make sure that Project > Build Automatically from the main menu is unchecked.

Generally speaking, this is better accomplished with an object instead since JavaScript doesn't really have associative arrays:

var foo = { bar: 0 };

Then use in to check for a key:

if ( !( 'bar' in foo ) ) {
    foo['bar'] = 42;
}

As was rightly pointed out in the comments below, this method is useful only when your keys will be strings, or items that can be represented as strings (such as numbers).

SQL Server databases use two files - an MDF file, known as the primary database file, which contains the schema and data, and a LDF file, which contains the logs. See wikipedia. A database may also use secondary database file, which normally uses a .ndf extension.

As John S. indicates, these file extensions are purely convention - you can use whatever you want, although I can't think of a good reason to do that.

More info on MSDN here and in Beginning SQL Server 2005 Administation (Google Books) here.

Give in the xml file of your layout android:scaleType="fitXY"
P.S : this applies to when the image is set with android:src="..." rather than android:background="..." as backgrounds are set by default to stretch and fit to the View.

I'm new to Python, but found a way to convert

2017-05-27T07:20:18.000-04:00 to

2017-05-27T07:20:18 without downloading new utilities.

from datetime import datetime, timedelta

time_zone1 = int("2017-05-27T07:20:18.000-04:00"[-6:][:3])
>>returns -04

item_date = datetime.strptime("2017-05-27T07:20:18.000-04:00".replace(".000", "")[:-6], "%Y-%m-%dT%H:%M:%S") + timedelta(hours=-time_zone1)

I'm sure there are better ways to do this without slicing up the string so much, but this got the job done.

It could be done purely by CSS using vh:

#page {
    display:block; 
    width:100%; 
    height:95vh !important; 
    overflow:hidden;
}

#tdcontent {
    float:left; 
    width:100%; 
    display:block;
}

#content {      
    float:left; 
    width:100%; 
    height:100%; 
    display:block; 
    overflow:scroll;
}

and the HTML

<div id="page">

   <div id="tdcontent"></div>
   <div id="content"></div>

</div>

I checked it, It works in all major browsers: Chrome, IE, and FireFox

Ensure position is on your element and set the z-index to a value higher than the elements you want to cover.

element {
    position: fixed;
    z-index: 999;
}

div {
    position: relative;
    z-index: 99;
}

It will probably require some more work than that but it's a start since you didn't post any code.

It is a clever means of encoding negative integers in such a way that approximately half of the combination of bits of a data type are reserved for negative integers, and the addition of most of the negative integers with their corresponding positive integers results in a carry overflow that leaves the result to be binary zero.

So, in 2's complement if one is 0x0001 then -1 is 0x1111, because that will result in a combined sum of 0x0000 (with an overflow of 1).

You need to access a geocoding service (i.e. from Google), there is no simple formula to transfer addresses to geo coordinates.

If you created your database following this tutorial: https://msdn.microsoft.com/en-au/data/jj193542.aspx

... then this might work:

1. Delete all .mdf and .ldf files in your project directory
2. Go to View / SQL Server Object Explorer and delete the database from the (localdb)\v11.0 subnode. See also https://stackoverflow.com/a/15832184/2279059

I think this is a much more cleaner solution when copying text:

copyToClipboard(item) {
    document.addEventListener('copy', (e: ClipboardEvent) => {
      e.clipboardData.setData('text/plain', (item));
      e.preventDefault();
      document.removeEventListener('copy', null);
    });
    document.execCommand('copy');
  }

And then just call copyToClipboard on click event in html. (click)="copyToClipboard('texttocopy')"

Try the SetField method:

table.Rows[i].SetField(column, value);
table.Rows[i].SetField(columnIndex, value);
table.Rows[i].SetField(columnName, value);

This should get the job done and is a bit "cleaner" than using Rows[i][j].

echo date("l M j, Y",$res1['timep']);
This is really good for converting a unix timestamp to a readable date along with day. Example: Thursday Jul 7, 2016

Platform-dependent, toolchain-dependent, ulimit-dependent, parameter-dependent.... It is not at all specified, and there are many static and dynamic properties that can influence it.

What about this :

substr($mystring.'/', 0, strpos($mystring, '/'))

Simply add a '/' to the end of mystring so you can be sure there is at least one ;)

The Port is not open. Thats why the machine refuses communication

u can use Dark theme Plugin

You didn't create your project as "Dynamic Web Project", so Eclipse doesn't recognize it like a web project. Create a new "Dynamic Web Project" or go to Properties ? Projects Facets and check Dynamic Web Module.

sed s/^M//g file1.txt > file2.txt

where ^M is typed by simultaneously pressing the 3 keys, ctrl + v + m

My proposition for the Which function:

function which($cmd) { get-command $cmd | % { $_.Path } }

PS C:\> which devcon

C:\local\code\bin\devcon.exe

As of data.table v1.13.0 you can use the function fcase() (fast-case) to do SQL-like CASE operations (also similar to dplyr::case_when()):

require(data.table)

dt <- data.table(name = c('cow','pig','eagle','pigeon','cow','eagle'))
dt[ , category := fcase(name %in% c('cow', 'pig'), 'mammal',
                        name %in% c('eagle', 'pigeon'), 'bird') ]

You should enable the unicode strings feature, and this is the default if you use v5.14;

You should not really use unicode identifiers esp. for foreign code via utf8 as they are insecure in perl5, only cperl got that right. See e.g. http://perl11.org/blog/unicode-identifiers.html

Regarding utf8 for your filehandles/streams: You need decide by yourself the encoding of your external data. A library cannot know that, and since not even libc supports utf8, proper utf8 data is rare. There's more wtf8, the windows aberration of utf8 around.

BTW: Moose is not really "Modern Perl", they just hijacked the name. Moose is perfect Larry Wall-style postmodern perl mixed with Bjarne Stroustrup-style everything goes, with an eclectic aberration of proper perl6 syntax, e.g. using strings for variable names, horrible fields syntax, and a very immature naive implementation which is 10x slower than a proper implementation. cperl and perl6 are the true modern perls, where form follows function, and the implementation is reduced and optimized.

you can use

<a href="\\computername\folder">Open folder</a>

in Internet Explorer

To call the method, you need to qualify function with self.. In addition to that, if you want to pass a filename, add a filename parameter (or other name you want).

class MyHandler(FileSystemEventHandler):

    def on_any_event(self, event):
        srcpath = event.src_path
        print (srcpath, 'has been ',event.event_type)
        print (datetime.datetime.now())
        filename = srcpath[12:]
        self.dropbox_fn(filename) # <----

    def dropbox_fn(self, filename):  # <-----
        print('In dropbox_fn:', filename)

You can simply delete this folder

/Library/Developer/CommandLineTools

Please note: This is the root /Library, not user's ~/Library).

With *nix, usually, you don't need a software to view an .img file. You can use the loop device to mount it and then every file manager to navigate it. Here you can find how. Sometime you need to install some package to manage strange filesystem like squashfs.

As others have mentioned, try stopPropagation().

And there is a second handler to try: event.cancelBubble = true; It's a IE specific handler, but it is supported in at least FF. Don't really know much about it, as I haven't used it myself, but it might be worth a shot, if all else fails.

When your form is maximized, set its minimum size = max size, so user cannot resize it.

    this.WindowState = FormWindowState.Maximized;
    this.MinimumSize = this.Size;
    this.MaximumSize = this.Size;

throw is for rethrowing a caught exception. This can be useful if you want to do something with the exception before passing it up the call chain.

Using throw without any arguments preserves the call stack for debugging purposes.

You should use the Time.IsZero() function instead:

func (Time) IsZero

func (t Time) IsZero() bool
IsZero reports whether t represents the zero time instant, January 1, year 1, 00:00:00 UTC.

Login into your server using a shell program like putty.

Type in the following command on the command line

zcat DB_File_Name.sql.gz | mysql -u username -p Target_DB_Name

where

DB_File_Name.sql.gz = full path of the sql.gz file to be imported

username = your mysql username

Target_DB_Name = database name where you want to import the database

When you hit enter in the command line, it will prompt for password. Enter your MySQL password.

You are done!

cast the integers to doubles.

It is stated in many places (adding custom functions into Array.prototype) playing with the Array prototype could be a bad idea, anyway I combined the best from various posts, I came with this, using modern Javascript:

    Object.defineProperty(Array.prototype, 'immutableMove', {
        enumerable: false,
        value: function (old_index, new_index) {
            var copy = Object.assign([], this)
            if (new_index >= copy.length) {
                var k = new_index - copy.length;
                while ((k--) + 1) { copy.push(undefined); }
            }
            copy.splice(new_index, 0, copy.splice(old_index, 1)[0]);
            return copy
        }
    });

    //how to use it
    myArray=[0, 1, 2, 3, 4];
    myArray=myArray.immutableMove(2, 4);
    console.log(myArray);
    //result: 0, 1, 3, 4, 2

Hope can be useful to anyone

For cases of appending to end of existing string:

string = "Sec_"
string += "C_type"
print(string)

results in

Sec_C_type

It is as simple as that ... C++ is providing you a function in STL (Standard Template Library) called sort which runs 20% to 50% faster than the hand-coded quick-sort.

Here is the sample code for it's usage:

std::sort(arr, arr + size);

Only redirection won't work, since there's nothing to connect the now-open file descriptors. So no, there is no way like this.

In your code you don't get the HttpResponse, so you won't see what the server side sends you back.

you need to get the Response similar to the way you get (make) the Request. So

public static bool SendAnSMSMessage(string message)
{
  var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
  httpWebRequest.ContentType = "text/json";
  httpWebRequest.Method = "POST";

  using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
  {
    string json = "{ \"method\": \"send\", " +
                      "  \"params\": [ " +
                      "             \"IPutAGuidHere\", " +
                      "             \"[email protected]\", " +
                      "             \"MyTenDigitNumberWasHere\", " +
                      "             \"" + message + "\" " +
                      "             ] " +
                      "}";

    streamWriter.Write(json);
  }
  var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
  using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
  {
    var responseText = streamReader.ReadToEnd();
    //Now you have your response.
    //or false depending on information in the response
    return true;        
  }
}

I also notice in the pennysms documentation that they expect a content type of "text/json" and not "application/json". That may not make a difference, but it's worth trying in case it doesn't work.

I found a post suggesting a solution for that. It's about to run:

svn resolve --accept working <YourPath>

which will claim the local version files as OK.
You can run it for single file or entire project catalogues.

A generic solution that will work with any testing framework (if your class is non-final) is to manually create your own mock.

1. Change your private method to protected.
2. In your test class extend the class
3. override the previously-private method to return whatever constant you want

This doesn't use any framework so its not as elegant but it will always work: even without PowerMock. Alternatively, you can use Mockito to do steps #2 & #3 for you, if you've done step #1 already.

To mock a private method directly, you'll need to use PowerMock as shown in the other answer.

You can get headers using below code

let main_headers = {}
this.http.post(url,
  {email: this.username, password: this.password},
  {'headers' : new HttpHeaders ({'Content-Type' : 'application/json'}), 'responseType': 'text', observe:'response'})
  .subscribe(response => {
    const keys = response.headers.keys();
    let headers = keys.map(key => {
      `${key}: ${response.headers.get(key)}`
        main_headers[key] = response.headers.get(key)
       }
      );
  });

later we can get the required header form the json object.

If you submit the form via Javascript (i.e. formElement.submit() or anything equivalent), then none of the submit buttons are considered successful and none of their values are included in the submitted data. (Note that if you submit the form by using submitElement.click() then the submit that you had a reference to is considered active; this doesn't really fall under the remit of your question since here the submit button is unambiguous but I thought I'd include it for people who read the first part and wonder how to make a submit button successful via JS form submission. Of course, the form's onsubmit handlers will still fire this way whereas they wouldn't via form.submit() so that's another kettle of fish...)

If the form is submitted by hitting Enter while in a non-textarea field, then it's actually down to the user agent to decide what it wants here. The specs don't say anything about submitting a form using the enter key while in a text entry field (if you tab to a button and activate it using space or whatever, then there's no problem as that specific submit button is unambiguously used). All it says is that a form must be submitted when a submit button is activated, it's not even a requirement that hitting enter in e.g. a text input will submit the form.

I believe that Internet Explorer chooses the submit button that appears first in the source; I have a feeling that Firefox and Opera choose the button with the lowest tabindex, falling back to the first defined if nothing else is defined. There's also some complications regarding whether the submits have a non-default value attribute IIRC.

The point to take away is that there is no defined standard for what happens here and it's entirely at the whim of the browser - so as far as possible in whatever you're doing, try to avoid relying on any particular behaviour. If you really must know, you can probably find out the behaviour of the various browser versions but when I investigated this a while back there were some quite convoluted conditions (which of course are subject to change with new browser versions) and I'd advise you to avoid it if possible!

For .NET DLLs you can use ildasm

    return response _x000D_

As of CMake 3.1+ the developers strongly discourage users from using file(GLOB or file(GLOB_RECURSE to collect lists of source files.

Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.

See the documentation here.

There are two goods answers ([1], [2]) here on SO detailing the reasons to manually list source files.

It is possible. E.g. with file(GLOB:

cmake_minimum_required(VERSION 2.8)

file(GLOB helloworld_SRC
     "*.h"
     "*.cpp"
)

add_executable(helloworld ${helloworld_SRC})

Note that this requires manual re-running of cmake if a source file is added or removed, since the generated build system does not know when to ask CMake to regenerate, and doing it at every build would increase the build time.

As of CMake 3.12, you can pass the CONFIGURE_DEPENDS flag to file(GLOB to automatically check and reset the file lists any time the build is invoked. You would write:

cmake_minimum_required(VERSION 3.12)

file(GLOB helloworld_SRC CONFIGURE_DEPENDS "*.h" "*.cpp")

This at least lets you avoid manually re-running CMake every time a file is added.

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

File object docs (for Python 2) here.

See Apple's guide to Using Swift with Cocoa and Objective-C. This guide covers how to use Objective-C and C code from Swift and vice versa and has recommendations for how to convert a project or mix and match Objective-C/C and Swift parts in an existing project.

The compiler automatically generates Swift syntax for calling C functions and Objective-C methods. As seen in the documentation, this Objective-C:

UITableView *myTableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStyleGrouped];

turns into this Swift code:

let myTableView: UITableView = UITableView(frame: CGRectZero, style: .Grouped)

Xcode also does this translation on the fly — you can use Open Quickly while editing a Swift file and type an Objective-C class name, and it'll take you to a Swift-ified version of the class header. (You can also get this by cmd-clicking on an API symbol in a Swift file.) And all the API reference documentation in the iOS 8 and OS X v10.10 (Yosemite) developer libraries is visible in both Objective-C and Swift forms (e.g. UIView).

By default TortoiseSVN always has a GUI (Graphical User Interface) associated with it. But on the installer (of version 1.7 and later) you can select the "command line client tools" option so you can call svn commands (like svn commit and svn update) from the command line.

Here's a screenshot of the "command line client tools" option in the installer, you need to make sure you select it:

openjdk-6 is a Java runtime, not a JDK (development kit which contains javac, for example). Install openjdk-6-jdk.

Maven also needs the JDK.

[EDIT] When the JDK is installed, use /usr/lib/jvm/java-6-openjdk for JAVA_HOME (i.e. without the jre part).

Perhaps:

Sub dateCNV()
    Dim N As Long, r As Range, s As String
    N = Cells(Rows.Count, "A").End(xlUp).Row
    For i = 1 To N
        Set r = Cells(i, "A")
        s = r.Text
        r.Clear
        r.Value = DateSerial(Left(s, 4), Mid(s, 6, 2), Right(s, 2))
    Next i
End Sub

This assumes that column A contains text values like 2013-12-25 with no header cell.

Take a look at this post on Java Ranch:

http://www.coderanch.com/t/300287/JDBC/java/Io-Exception-Network-Adapter-could

The simplest way to get equal height columns, without the ugly side effects that come along with absolute positioning, is to use the display: table properties:

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  display: table;
}

.div2, .div3 {
  display: table-cell;
}
.div2 {
  width:150px;
  height:auto;
  background-color: #F4A460;  

}
.div3 {
  width:150px;
  height:auto;
  background-color: #FFFFE0;  
}

http://jsfiddle.net/E4Zgj/21/

Now, if your goal is to have .div2 so that it is only as tall as it needs to be to contain its content while .div3 is at least as tall as .div2 but still able to expand if its content makes it taller than .div2, then you need to use flexbox. Flexbox support isn't quite there yet (IE10, Opera, Chrome. Firefox follows an old spec, but is following the current spec soon).

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  display: flex;
  align-items: flex-start;
}

.div2 {
  width:150px;
  background-color: #F4A460;
}

.div3 {
  width:150px;
  background-color: #FFFFE0;
  align-self: stretch;
}

The following categories of variables are classified as initially unassigned:

• Instance variables of initially unassigned struct variables.
• Output parameters, including the this variable of struct instance constructors.
• Local variables , except those declared in a catch clause or a foreach statement.

The following categories of variables are classified as initially assigned:

• Static variables.

Did you try D3.js? Here is a good example.

You can also have a look at this related question. That user reported that using a join provided better performance than using a sub query.

You can list breakpoints with:

info break

This will list all breakpoints. Then a breakpoint can be deleted by its corresponding number:

del 3

For example:

 (gdb) info b
 Num     Type           Disp Enb Address    What
  3      breakpoint     keep y   0x004018c3 in timeCorrect at my3.c:215
  4      breakpoint     keep y   0x004295b0 in avi_write_packet atlibavformat/avienc.c:513
 (gdb) del 3
 (gdb) info b

If you installed ES using the RPM/DEB packages as provided (as you seem to have), you can adjust this by editing the init script (/etc/init.d/elasticsearch on RHEL/CentOS). If you have a look in the file you'll see a block with the following:

export ES_HEAP_SIZE
export ES_HEAP_NEWSIZE
export ES_DIRECT_SIZE
export ES_JAVA_OPTS
export JAVA_HOME

To adjust the size, simply change the ES_HEAP_SIZE line to the following:

export ES_HEAP_SIZE=xM/xG

(where x is the number of MB/GB of RAM that you would like to allocate)

Example:

export ES_HEAP_SIZE=1G

Would allocate 1GB.

Once you have edited the script, save and exit, then restart the service. You can check if it has been correctly set by running the following:

ps aux | grep elasticsearch

And checking for the -Xms and -Xmx flags in the java process that returns:

/usr/bin/java -Xms1G -Xmx1G

Hope this helps :)

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

Simplest solution

Use numpy.dot or a.dot(b). See the documentation here.

>>> a = np.array([[ 5, 1 ,3], 
                  [ 1, 1 ,1], 
                  [ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])

This occurs because numpy arrays are not matrices, and the standard operations *, +, -, / work element-wise on arrays. Instead, you could try using numpy.matrix, and * will be treated like matrix multiplication.

Other Solutions

Also know there are other options:

• As noted below, if using python3.5+ the @ operator works as you'd expect:

  >>> print(a @ b)
  array([16, 6, 8])
  

• If you want overkill, you can use numpy.einsum. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.

  >>> np.einsum('ji,i->j', a, b)
  array([16, 6, 8])
  

• As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul, which works like numpy.dot with two major exceptions: no scalar multiplication but it works with stacks of matrices.

  >>> np.matmul(a, b)
  array([16, 6, 8])
  

• numpy.inner functions the same way as numpy.dot for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).

  >>> np.inner(a, b)
  array([16, 6, 8])
  
  # Beware using for matrix-matrix multiplication though!
  >>> b = a.T
  >>> np.dot(a, b)
  array([[35,  9, 10],
         [ 9,  3,  4],
         [10,  4,  6]])
  >>> np.inner(a, b) 
  array([[29, 12, 19],
         [ 7,  4,  5],
         [ 8,  5,  6]])
  

Rarer options for edge cases

• If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot with the optional argument axes=1:

  >>> np.tensordot(a, b, axes=1)
  array([16,  6,  8])
  

• Don't use numpy.vdot if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m vs n).

You can put df_try inside a list and then do what you have in mind:

>>> df.append([df_try]*5,ignore_index=True)

And there is another possibility (not in this case) when working with ajax(XMLhttpRequest), while sending information back to the client end you should use res.send(responsetext) instead of res.end(responsetext)

I changed my website and app bindings to a new port and it worked for me. This error might occur because the port the website uses is not available. Hence sometimes the problem is solved by simply restarting the machine

-Edit-

Alternative (and easier) solution:reference

1. Get PID of process which is using the port CMD command- netstat -aon | findstr 0.0:80

2. Use the PID to get process name -

tasklist /FI "PID eq "

3. Open task manager, find this process and stop it.

(Note- Make sure you do not stop Net.tcp services)

A very simple solution: replace https:// with git://

Use git://the.repository instead of https://the.repository and will work.

I've had this problem on Windows with TortoiseGit and this solved it.

hymloth and sven's answers work, but they do not modify the list (the create a new one). If you need the object modification you need to assign to a slice:

x[:] = [value for value in x if len(value)==2]

However, for large lists in which you need to remove few elements, this is memory consuming, but it runs in O(n).

glglgl's answer suffers from O(n²) complexity, because list.remove is O(n).

Depending on the structure of your data, you may prefer noting the indexes of the elements to remove and using the del keywork to remove by index:

to_remove = [i for i, val in enumerate(x) if len(val)==2]
for index in reversed(to_remove): # start at the end to avoid recomputing offsets
    del x[index]

Now del x[i] is also O(n) because you need to copy all elements after index i (a list is a vector), so you'll need to test this against your data. Still this should be faster than using remove because you don't pay for the cost of the search step of remove, and the copy step cost is the same in both cases.

[edit] Very nice in-place, O(n) version with limited memory requirements, courtesy of @Sven Marnach. It uses itertools.compress which was introduced in python 2.7:

from itertools import compress

selectors = (len(s) == 2 for s in x)
for i, s in enumerate(compress(x, selectors)): # enumerate elements of length 2
    x[i] = s # move found element to beginning of the list, without resizing
del x[i+1:]  # trim the end of the list

Some clarifications (not really an answer)

In kubernetes, every pod gets assigned an IP address, and every container in the pod gets assigned that same IP address. Thus, as Alex Robinson stated in his answer, you can just use hostname -i inside your container to get the pod IP address.

I tested with a pod running two dumb containers, and indeed hostname -i was outputting the same IP address inside both containers. Furthermore, that IP was equivalent to the one obtained using kubectl describe pod from outside, which validates the whole thing IMO.

However, PiersyP's answer seems more clean to me.

Sources

From kubernetes docs:

The applications in a pod all use the same network namespace (same IP and port space), and can thus “find” each other and communicate using localhost. Because of this, applications in a pod must coordinate their usage of ports. Each pod has an IP address in a flat shared networking space that has full communication with other physical computers and pods across the network.

Another piece from kubernetes docs:

Until now this document has talked about containers. In reality, Kubernetes applies IP addresses at the Pod scope - containers within a Pod share their network namespaces - including their IP address. This means that containers within a Pod can all reach each other’s ports on localhost.

You can use the apply function of the Series object:

>>> df = pd.DataFrame([['  a  ', 10], ['  c  ', 5]])
>>> df[0][0]
'  a  '
>>> df[0] = df[0].apply(lambda x: x.strip())
>>> df[0][0]
'a'

Note the usage of strip and not the regex which is much faster

Another option - use the apply function of the DataFrame object:

>>> df = pd.DataFrame([['  a  ', 10], ['  c  ', 5]])
>>> df.apply(lambda x: x.apply(lambda y: y.strip() if type(y) == type('') else y), axis=0)

   0   1
0  a  10
1  c   5

IF OBJECT_ID('master..test') is not null Drop table test

CREATE TABLE test (ID INTEGER, NAME VARCHAR (50), VALUE INTEGER );
INSERT INTO test VALUES (1, 'A', 4);
INSERT INTO test VALUES (1, 'A', 5);
INSERT INTO test VALUES (1, 'B', 8);
INSERT INTO test VALUES (2, 'C', 9);

select distinct NAME , LIST = Replace(Replace(Stuff((select ',', +Value from test where name = _a.name for xml path('')), 1,1,''),'<Value>', ''),'</Value>','') from test _a order by 1 desc

My table name is test , and for concatination I use the For XML Path('') syntax. The stuff function inserts a string into another string. It deletes a specified length of characters in the first string at the start position and then inserts the second string into the first string at the start position.

STUFF functions looks like this : STUFF (character_expression , start , length ,character_expression )

character_expression Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data.

start Is an integer value that specifies the location to start deletion and insertion. If start or length is negative, a null string is returned. If start is longer than the first character_expression, a null string is returned. start can be of type bigint.

length Is an integer that specifies the number of characters to delete. If length is longer than the first character_expression, deletion occurs up to the last character in the last character_expression. length can be of type bigint.

I had the same problem, and finally I found that I forgot to add the selenium-server-standalone-version.jar. I had only added the client jar, selenium-java-version.jar.

Using !important is generally not a good idea in the code itself, but it can be useful in various overrides.

I use Firefox and a dotjs plugin which essentially can run your own custom JS or CSS code on specified websites automatically.

Here's the code for it I use on Twitter that makes the tweet input field always stay on my screen no matter how far I scroll, and for the hyperlinks to always remain the same color.

a, a * {
  color: rgb(34, 136, 85) !important;  
}

.count-inner {
 color: white !important;   
}

.timeline-tweet-box {
 z-index: 99 !important;
position: fixed !important;
left: 5% !important;   
}

Since, thankfully, Twitter developers don't use !important properties much, I can use it to guarantee that the specified styles will be definitely overridden, because without !important they were not overridden sometimes. It really came in handy for me there.

Here is the good function for pre PHP 5: I added GMT difference at the end, it's not hardcoded.

function iso8601($time=false) {
    if ($time === false) $time = time();
    $date = date('Y-m-d\TH:i:sO', $time);
    return (substr($date, 0, strlen($date)-2).':'.substr($date, -2));
}

Another way would be to use .Net parser for HttpRequest. To do that you need to use a bit of reflection and simple class for WorkerRequest.

First create class that derives from HttpWorkerRequest (for simplicity you can use SimpleWorkerRequest):

public class MyWorkerRequest : SimpleWorkerRequest
{
    private readonly string _size;
    private readonly Stream _data;
    private string _contentType;

    public MyWorkerRequest(Stream data, string size, string contentType)
        : base("/app", @"c:\", "aa", "", null)
    {
        _size = size ?? data.Length.ToString(CultureInfo.InvariantCulture);
        _data = data;
        _contentType = contentType;
    }

    public override string GetKnownRequestHeader(int index)
    {
        switch (index)
        {
            case (int)HttpRequestHeader.ContentLength:
                return _size;
            case (int)HttpRequestHeader.ContentType:
                return _contentType;
        }
        return base.GetKnownRequestHeader(index);
    }

    public override int ReadEntityBody(byte[] buffer, int offset, int size)
    {
        return _data.Read(buffer, offset, size);
    }

    public override int ReadEntityBody(byte[] buffer, int size)
    {
        return ReadEntityBody(buffer, 0, size);
    }
}

Then wherever you have you message stream create and instance of this class. I'm doing it like that in WCF Service:

[WebInvoke(Method = "POST",
               ResponseFormat = WebMessageFormat.Json,
               BodyStyle = WebMessageBodyStyle.Bare)]
    public string Upload(Stream data)
    {
        HttpWorkerRequest workerRequest =
            new MyWorkerRequest(data,
                                WebOperationContext.Current.IncomingRequest.ContentLength.
                                    ToString(CultureInfo.InvariantCulture),
                                WebOperationContext.Current.IncomingRequest.ContentType
                );

And then create HttpRequest using activator and non public constructor

var r = (HttpRequest)Activator.CreateInstance(
            typeof(HttpRequest),
            BindingFlags.Instance | BindingFlags.NonPublic,
            null,

After that in r.Files you will have files from your stream.

The problem is the padding of the font on the textview. Just add to your textview:

android:includeFontPadding="false"

If the problem is 100% here

EffectSelectorForm effectSelectorForm = new EffectSelectorForm(Effects);

There's only one possible explanation: property/variable "Effects" is not initialized properly... Debug your code to see what you pass to your objects.

EDIT after several hours

There were some problems:

• MEF attribute [Import] didn't work as expected, so we replaced it for the time being with a manually populated List<>. While the collection was null, it was causing exceptions later in the code, when the method tried to get the type of the selected item and there was none.

• several event handlers weren't wired up to control events

Some problems are still present, but I believe OP's original problem has been fixed. Other problems are not related to this one.

Use -d (full list of file tests)

if (-d "cgi-bin") {
    # directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
    # cgi-bin exists but is not a directory
}
else {
    # nothing called cgi-bin exists
}

As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.

Bootstrap provide us with .disabled class. Please use it.

But .disabled class only works when the 'a' tag already has class 'btn'. It doesn' t work on any old 'a' tag. The btn class may not be appropriate in some context as it has style connotations. Under the covers, the .disabled class sets pointer-events to none, so you can make CSS to do the same thing as Saroj Aryal and Vitrilo have sugested. (Thank you, Les Nightingill for this advice).

I guess problem is in width attributes in table and td remove 'px' for example

<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">

Should be

<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">

I ran into this problem with my new Nexus 4 and an APK built with Adobe AIR. I already had android:installLocation="preferExternal" in my manifest. I noticed I was also calling adb install with the -s option (Install package on the shared mass storage such as sdcard.) which seemed like overkill.

Removing the -s flag from adb install fixed the issue for me.

Simple working camera app avoiding the null intent problem

- all changed code included in this reply; close to android tutorial

I've been spending plenty of time on this issue, so I decided to create an account and share my outcomes with you.

The official android tutorial "Taking Photos Simply" turned out to not quite hold what it promised. The code provided there did not work on my device: a Samsung Galaxy S4 Mini GT-I9195 running android version 4.4.2 / KitKat / API Level 19.

I figured out that the main problem was the following line in the method invoked when capturing the photo (dispatchTakePictureIntent in the tutorial):

takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);

It resulted in the intent subsequently catched by onActivityResult being null.

To solve this problem, I pulled much inspiration out of earlier replies here and some helpful posts on github (mostly this one by deepwinter - big thanks to him; you might want to check out his reply on a closely related post as well).

Following these pleasant pieces of advice, I chose the strategy of deleting the mentioned putExtra line and doing the corresponding thing of getting back the taken picture from the camera within the onActivityResult() method instead. The decisive lines of code to get back the bitmap associated with the picture are:

        Uri uri = intent.getData();
        Bitmap bitmap = null;
        try {
            bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
        } catch (IOException e) {
            e.printStackTrace();
        }

I created an exemplary app which just has the ability to take a picture, save it on the SD card and display it. I think this might be helpful to people in the same situation as me when I stumbled on this issue, since the current help suggestions mostly refer to rather extensive github posts which do the thing in question but aren't too easy to oversee for newbies like me. With respect to the file system Android Studio creates per default when creating a new project, I just had to change three files for my purpose:

activity_main.xml :

<?xml version="1.0" encoding="utf-8"?>

</manifest>

Note that the solution I found for the problem also led to a simplification of the android manifest file: the changes suggested by the android tutorial in terms of adding a provider are no longer needed since I am not making use of any in my java code. Hence, only few standard lines -mostly regarding permissions- had to be added to the manifest file.

It might additionally be valuable to point out that Android Studio's autoimport may not be capable of handling java.text.SimpleDateFormat and java.util.Date. I had to import both of them manually.

The sender is of type ListView not ListViewItem.

    private void listViewTriggers_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        ListView triggerView = sender as ListView;
        if (triggerView != null)
        {

I have open-sourced a UIButton subclass, STAButton, to fill in this gaping functionality hole. Available under the MIT license. Works for iOS 7+ (I have not tested with older iOS versions).

have you checked RSE (Remote System Explorer) ? I think it's pretty close to what you want to achieve.

a blog post about it, with screenshots

The selected answer works, but it could use some improvement.

• The options should probably be initialized to default values.
• It would be nice to preserve %0 as well as the required args %1 and %2.
• It becomes a pain to have an IF block for every option, especially as the number of options grows.
• It would be nice to have a simple and concise way to quickly define all options and defaults in one place.
• It would be good to support stand-alone options that serve as flags (no value following the option).
• We don't know if an arg is enclosed in quotes. Nor do we know if an arg value was passed using escaped characters. Better to access an arg using %~1 and enclose the assignment within quotes. Then the batch can rely on the absence of enclosing quotes, but special characters are still generally safe without escaping. (This is not bullet proof, but it handles most situations)

My solution relies on the creation of an OPTIONS variable that defines all of the options and their defaults. OPTIONS is also used to test whether a supplied option is valid. A tremendous amount of code is saved by simply storing the option values in variables named the same as the option. The amount of code is constant regardless of how many options are defined; only the OPTIONS definition has to change.

EDIT - Also, the :loop code must change if the number of mandatory positional arguments changes. For example, often times all arguments are named, in which case you want to parse arguments beginning at position 1 instead of 3. So within the :loop, all 3 become 1, and 4 becomes 2.

There really isn't that much code. Most of the code above is comments. Here is the exact same code, without the comments.

This solution provides Unix style arguments within a Windows batch. This is not the norm for Windows - batch usually has the options preceding the required arguments and the options are prefixed with /.

The techniques used in this solution are easily adapted for a Windows style of options.

• The parsing loop always looks for an option at %1, and it continues until arg 1 does not begin with /
• Note that SET assignments must be enclosed within quotes if the name begins with /.
  SET /VAR=VALUE fails
  SET "/VAR=VALUE" works. I am already doing this in my solution anyway.
• The standard Windows style precludes the possibility of the first required argument value starting with /. This limitation can be eliminated by employing an implicitly defined // option that serves as a signal to exit the option parsing loop. Nothing would be stored for the // "option".
  
  

Update 2015-12-28: Support for ! in option values

In the code above, each argument is expanded while delayed expansion is enabled, which means that ! are most likely stripped, or else something like !var! is expanded. In addition, ^ can also be stripped if ! is present. The following small modification to the un-commented code removes the limitation such that ! and ^ are preserved in option values.

you can get List value without using Type object.

EvalClassName[] evalClassName;
ArrayList<EvalClassName> list;
evalClassName= new Gson().fromJson(JSONArrayValue.toString(),EvalClassName[].class);
list = new ArrayList<>(Arrays.asList(evalClassName));

I have tested it and it is working.

To make sure you're always on the safe side, without getting all kinds of unwanted code insertion use FILTERS:

echo filter_input(INPUT_GET,"link",FILTER_SANITIZE_STRING);

More reading on php.net function filter_input, or check out the description of the different filters

No, you don't cast the result of malloc().

In general, you don't cast to or from void *.

A typical reason given for not doing so is that failure to #include <stdlib.h> could go unnoticed. This isn't an issue anymore for a long time now as C99 made implicit function declarations illegal, so if your compiler conforms to at least C99, you will get a diagnostic message.

But there's a much stronger reason not to introduce unnecessary pointer casts:

In C, a pointer cast is almost always an error. This is because of the following rule (§6.5 p7 in N1570, the latest draft for C11):

An object shall have its stored value accessed only by an lvalue expression that has one of the following types:
— a type compatible with the effective type of the object,
— a qualified version of a type compatible with the effective type of the object,
— a type that is the signed or unsigned type corresponding to the effective type of the object,
— a type that is the signed or unsigned type corresponding to a qualified version of the effective type of the object,
— an aggregate or union type that includes one of the aforementioned types among its members (including, recursively, a member of a subaggregate or contained union), or
— a character type.

This is also known as the strict aliasing rule. So the following code is undefined behavior:

long x = 5;
double *p = (double *)&x;
double y = *p;

And, sometimes surprisingly, the following is as well:

struct foo { int x; };
struct bar { int x; int y; };
struct bar b = { 1, 2};
struct foo *p = (struct foo *)&b;
int z = p->x;

Sometimes, you do need to cast pointers, but given the strict aliasing rule, you have to be very careful with it. So, any occurrence of a pointer cast in your code is a place you have to double-check for its validity. Therefore, you never write an unnecessary pointer cast.

tl;dr

In a nutshell: Because in C, any occurrence of a pointer cast should raise a red flag for code requiring special attention, you should never write unnecessary pointer casts.

Side notes:

• There are cases where you actually need a cast to void *, e.g. if you want to print a pointer:

  int x = 5;
  printf("%p\n", (void *)&x);
  

  The cast is necessary here, because printf() is a variadic function, so implicit conversions don't work.

• In C++, the situation is different. Casting pointer types is somewhat common (and correct) when dealing with objects of derived classes. Therefore, it makes sense that in C++, the conversion to and from void * is not implicit. C++ has a whole set of different flavors of casting.

I've had this problem too, I had just forgotten to type workon myproject in the terminal before executing my program.

The thread is old, but maybe someone is still interested. The shortest form I found is further improvement on the example from ?lex and bmargulies. The execution tag will look like:

<execution>
    <id>TheNameOfTheRelevantExecution</id>
    <phase/>
</execution>

2 points I want to highlight:

1. phase is set to nothing, which looks less hacky than 'none', though still a hack.
2. id must be the same as execution you want to override. If you don't specify id for execution, Maven will do it implicitly (in a way not expected intuitively by you).

That what manual says about setOnClickListener method is:

public void setOnClickListener (View.OnClickListener l)

Added in API level 1 Register a callback to be invoked when this view is clicked. If this view is not clickable, it becomes clickable.

Parameters

l View.OnClickListener: The callback that will run

And normally you have to use it like this

public class ExampleActivity extends Activity implements OnClickListener {
    protected void onCreate(Bundle savedValues) {
        ...
        Button button = (Button)findViewById(R.id.corky);
        button.setOnClickListener(this);
    }

    // Implement the OnClickListener callback
    public void onClick(View v) {
      // do something when the button is clicked
    }
    ...
}

• If one wants to have multiple number of instances of the same class, but only if the args or kwargs are different, one can use the third-party python package Handy Decorators (package decorators).
• Ex.
  1. If you have a class handling serial communication, and to create an instance you want to send the serial port as an argument, then with traditional approach won't work
  2. Using the above mentioned decorators, one can create multiple instances of the class if the args are different.
  3. For same args, the decorator will return the same instance which is already been created.

>>> from decorators import singleton
>>>
>>> @singleton
... class A:
...     def __init__(self, *args, **kwargs):
...         pass
...
>>>
>>> a = A(name='Siddhesh')
>>> b = A(name='Siddhesh', lname='Sathe')
>>> c = A(name='Siddhesh', lname='Sathe')
>>> a is b  # has to be different
False
>>> b is c  # has to be same
True
>>>

How to write a compound statement with if?

You can write a compound statement in an if block using parenthesis. The first parenthesis must come on the line with the if and the second on a line by itself.

if %ERRORLEVEL% == 0 (
    echo ErrorLevel is zero
    echo A second statement
) else if %ERRORLEVEL% == 1 (
    echo ErrorLevel is one
    echo A second statement
) else (
   echo ErrorLevel is > 1
   echo A second statement

I installed WAMPServer 2.5 (32-bit) and also encountered an oci_connect error. I also had Oracle 11g client (32-bit) installed. The common fix I read in other posts was to alter the php.ini file in your C:\wamp\bin\php\php5.5.12 directory, however this never worked for me. Maybe I misunderstood, but I found that if you alter the php.ini file in the C:\wamp\bin\apache\apache2.4.9 directory instead, you will get the results you want. The only thing I altered in the apache php.ini file was remove the semicolon to extension=php_oci8_11g.dll in order to enable it. I then restarted all the services and it now works! I hope this works for you.

The "overhead" with cursors is merely part of the API. Cursors are how parts of the RDBMS work under the hood. Often CREATE TABLE and INSERT have SELECT statements, and the implementation is the obvious internal cursor implementation.

Using higher-level "set-based operators" bundles the cursor results into a single result set, meaning less API back-and-forth.

Cursors predate modern languages that provide first-class collections. Old C, COBOL, Fortran, etc., had to process rows one at a time because there was no notion of "collection" that could be used widely. Java, C#, Python, etc., have first-class list structures to contain result sets.

The Slow Issue

In some circles, the relational joins are a mystery, and folks will write nested cursors rather than a simple join. I've seen truly epic nested loop operations written out as lots and lots of cursors. Defeating an RDBMS optimization. And running really slowly.

Simple SQL rewrites to replace nested cursor loops with joins and a single, flat cursor loop can make programs run in 100th the time. [They thought I was the god of optimization. All I did was replace nested loops with joins. Still used cursors.]

This confusion often leads to an indictment of cursors. However, it isn't the cursor, it's the misuse of the cursor that's the problem.

The Size Issue

For really epic result sets (i.e., dumping a table to a file), cursors are essential. The set-based operations can't materialize really large result sets as a single collection in memory.

Alternatives

I try to use an ORM layer as much as possible. But that has two purposes. First, the cursors are managed by the ORM component. Second, the SQL is separated from the application into a configuration file. It's not that the cursors are bad. It's that coding all those opens, closes and fetches is not value-add programming.

PHP and references are somewhat unintuitive. If used appropriately references in the right places can provide large performance improvements or avoid very ugly workarounds and unusual code.

The following will produce an error:

 function f(&$v){$v = true;}
 f(&$v);

 function f($v){$v = true;}
 f(&$v);

None of these have to fail as they could follow the rules below but have no doubt been removed or disabled to prevent a lot of legacy confusion.

If they did work, both involve a redundant conversion to reference and the second also involves a redundant conversion back to a scoped contained variable.

The second one used to be possible allowing a reference to be passed to code that wasn't intended to work with references. This is extremely ugly for maintainability.

This will do nothing:

 function f($v){$v = true;}
 $r = &$v;
 f($r);

More specifically, it turns the reference back into a normal variable as you have not asked for a reference.

This will work:

 function f(&$v){$v = true;}
 f($v);

This sees that you are passing a non-reference but want a reference so turns it into a reference.

What this means is that you can't pass a reference to a function where a reference is not explicitly asked for making it one of the few areas where PHP is strict on passing types or in this case more of a meta type.

If you need more dynamic behaviour this will work:

 function f(&$v){$v = true;}
 $v = array(false,false,false);
 $r = &$v[1];
 f($r);

Here it sees that you want a reference and already have a reference so leaves it alone. It may also chain the reference but I doubt this.

You use INNER JOIN to return all rows from both tables where there is a match. i.e. In the resulting table all the rows and columns will have values.

In OUTER JOIN the resulting table may have empty columns. Outer join may be either LEFT or RIGHT.

LEFT OUTER JOIN returns all the rows from the first table, even if there are no matches in the second table.

RIGHT OUTER JOIN returns all the rows from the second table, even if there are no matches in the first table.

copy module creates the directory if it's not there. In this case it created the resolved.conf.d directory

- name: put fallback_dns.conf in place                                                                 
  copy:

You can use array.slice(0,1) // First index is removed and array is returned.

@Boris's solution is VERY good but the view can sometimes be corrupted.

For the perfect alignment, use the below code

override func viewDidLoad() {
super.viewDidLoad()            
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)}

Functions:

@objc func keyboardWillShow(notification: NSNotification) {        
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
    if self.view.frame.origin.y == 0{
        self.view.frame.origin.y -= keyboardSize.height
    }
}}    

And,

@objc func keyboardWillHide(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
    if self.view.frame.origin.y != 0{
        self.view.frame.origin.y = 0 
    }
} }

Use jQuery's IsNumeric method.

http://api.jquery.com/jQuery.isNumeric/

if ($.isNumeric(id)) {
   //it's numeric
}

CORRECTION: that would not ensure an integer. This would:

if ( (id+"").match(/^\d+$/) ) {
   //it's all digits
}

That, of course, doesn't use jQuery, but I assume jQuery isn't actually mandatory as long as the solution works

This is what worked for me:

sc.exe create MongoDB binPath= "d:\MongoDB\bin\mongod.exe --service --config=d:\MongoDB\bin\mongod.config" displayname= "MongoDB 2.6 Standard" start= "auto"

escaping the binPath was failing for me as described in the Mongo documentation

Failed:

sc.exe create MongoDB binPath= "\"C:\Program Files\MongoDB 2.6 Standard\bin\mongod.exe\" --service --config=\"C:\Program Files\MongoDB 2.6 Standard\mongod.cfg\"" DisplayName= "MongoDB 2.6 Standard" start= "auto"

Realizing I had a detached head without knowing how I managed to get it (like three commits away), I also found out that trying to merge, rebase or cherry-pick triggered hundreds of merge-conflicts, so I took a different approach:

1. (Assuming everything is committed (working tree is "clean"))

2. Save my commit messages: git log > /tmp/log

3. Save my working tree: mkdir /tmp/backup && cp -a all_my files_and_directories /tmp/backup

4. Revert to master: git checkout master

5. Remove all the working files and directories: rm ...

6. Use the backup: cp -a /tmp/backup/. .

7. git add and git commit using messages from saved /tmp/log, maybe repeating it with different sub-sets of files...

The disadvantage is that you loose your commit history if one file was changed multiple times since master, but in the end I had a clean master.

use this class inside nav tag

class="navbar navbar-expand-lg navbar-light bg-light sticky-top"

For bootstrap 4

from collections import Counter

n = int(input())
data = sorted([int(i) for i in input().split()])

sorted(sorted(Counter(data).items()), key = lambda x: x[1], reverse = True)[0][0]

print(Mean)

The Counter(data) counts the frequency and returns a defaultdict. sorted(Counter(data).items()) sorts using the keys, not the frequency. Finally, need to sorted the frequency using another sorted with key = lambda x: x[1]. The reverse tells Python to sort the frequency from the largest to the smallest.

An alternative is to normalize the data. Below are three sets of data with widely varying ranges. In the top chart you can see the variation in one series clearly, in another not so clearly, and the third not at all.

In the second range, I have adjusted the series names to include the data range, using this formula in cell C15 and copying it to D15:E15

=C2&" ("&MIN(C3:C9)&" to "&MAX(C3:C9)&")"

I have normalized the values in the data range using this formula in C15 and copying it to the entire range C16:E22

=100*(C3-MIN(C$3:C$9))/(MAX(C$3:C$9)-MIN(C$3:C$9))

In the second chart, you can see a pattern: all series have a low in January, rising to a high in March, and dropping to medium-low value in June or July.

You can modify the normalizing formula however you need:

=100*C3/MAX(C$3:C$9)

=C3/MAX(C$3:C$9)

=(C3-AVERAGE(C$3:C$9))/STDEV(C$3:C$9)

etc.

Zip files have a table of contents. Every zip utility should have the ability to query just the TOC. Or you can use a command line program like 7zip -t to print the table of contents and redirect it to a text file.

The problem is that you call remove on the root of your Firebase:

ref = new Firebase("myfirebase.com")
ref.remove();

This will remove the entire Firebase through the API.

You'll typically want to remove specific child nodes under it though, which you do with:

ref.child(key).remove();

If you don't want to copy the whole tree (with subdirs etc), use or glob.glob("path/to/dir/*.*") to get a list of all the filenames, loop over the list and use shutil.copy to copy each file.

for filename in glob.glob(os.path.join(source_dir, '*.*')):
    shutil.copy(filename, dest_dir)

dat1 and dat2 are Strings in JavaScript. There is no getTime function on the String prototype. I believe you want the Date.parse() function: http://www.w3schools.com/jsref/jsref_parse.asp

You would use it like this:

var date = Date.parse(dat1);

I have been through a lot of trouble so I came up with my own solution, I created this script, just set the path inside script and db name and run it, it will do the trick

#!/bin/bash

FILES= #absolute or relative path to dump directory
DB=`db` #db name
for file in $FILES
do

    name=$(basename $file)
    collection="${name%.*}"
    echo `mongoimport --db "$DB" --file "$name" --collection "$collection"`

done

<?php
  for ($n = 0; $n <= 7; $n++) {
    echo '<p>'.($n + 1).'</p>';
    echo '<p>'.($n * 2 + 1).'</p>';
  }
?>

I don't know why everyone is using 2 copies of the same list to solve this. This uses too much RAM...

Why not just hide the elements that are not found, and simply store their index in a Set to be able to restore them later? That's much less RAM especially if your objects are quite large.

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.SampleViewHolders>{
    private List<MyObject> myObjectsList; //holds the items of type MyObject
    private Set<Integer> foundObjects; //holds the indices of the found items

    public class SampleViewHolders extends RecyclerView.ViewHolder implements View.OnClickListener
    {
        public ImageView imgImageView;
        public TextView nameTextView;

        private final CardView layout;
        private final CardView.LayoutParams hiddenLayoutParams;
        private final CardView.LayoutParams shownLayoutParams;

        
        public SampleViewHolders(View itemView)
        {
            super(itemView);
            itemView.setOnClickListener(this);
            imgImageView = (ImageView) itemView.findViewById(R.id.some_image_view);
            nameTextView = (TextView) itemView.findViewById(R.id.display_name_textview);

            layout = itemView.findViewById(R.id.card_view); //card_view is the id of my androidx.cardview.widget.CardView in my xml layout
            //prepare hidden layout params with height = 0, and visible layout params for later - see hideLayout() and showLayout()
            hiddenLayoutParams = new CardView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            hiddenLayoutParams.height = 0;
            shownLayoutParams = new CardView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
        }

        @Override

        }

        private void showLayout() {
            //show the layout
            layout.setLayoutParams(shownLayoutParams);
        }
    }
}

And I simply have an EditText as my search box:

cardsSearchTextView.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void afterTextChanged(Editable editable) {
                myViewAdapter.findObject(editable.toString().toLowerCase());
            }
        });

Result:

Since you have an object, not a jQuery wrapper, you need to use a different variant of $.each()

$.each(json, function (key, data) {
    console.log(key)
    $.each(data, function (index, data) {
        console.log('index', data)
    })
})

You can use the REGEXP_LIKE function as:

SELECT X 
FROM myTable 
WHERE REGEXP_LIKE(X, '^[[:digit:]]+$');

Sample run:

SQL> SELECT X FROM SO;

12c
123
abc
a12

SQL> SELECT X  FROM SO WHERE REGEXP_LIKE(X, '^[[:digit:]]+$');

Use DialogFragment over AlertDialog:

• Since the introduction of API level 13:

  the showDialog method from Activity is deprecated. Invoking a dialog elsewhere in code is not advisable since you will have to manage the the dialog yourself (e.g. orientation change).

• Difference DialogFragment - AlertDialog

  Are they so much different? From Android reference regarding DialogFragment:

  A DialogFragment is a fragment that displays a dialog window, floating on top of its activity's window. This fragment contains a Dialog object, which it displays as appropriate based on the fragment's state. Control of the dialog (deciding when to show, hide, dismiss it) should be done through the API here, not with direct calls on the dialog.

• Other notes

  • Fragments are a natural evolution in the Android framework due to the diversity of devices with different screen sizes.
  • DialogFragments and Fragments are made available in the support library which makes the class usable in all current used versions of Android.

When you type "java -version", you see three version numbers - the java version (on mine, that's "1.6.0_07"), the Java SE Runtime Environment version ("build 1.6.0_07-b06"), and the HotSpot version (on mine, that's "build 10.0-b23, mixed mode"). I suspect the "11.0" you are seeing is the HotSpot version.

Update: HotSpot is (or used to be, now they seem to use it to mean the whole VM) the just-in-time compiler that is built in to the Java Virtual Machine. God only knows why Sun gives it a separate version number.

By combining all the given answers, this method should work on all environments:

public static void clearConsole() {
    try {
        if (System.getProperty("os.name").contains("Windows")) {
            new ProcessBuilder("cmd", "/c", "cls").inheritIO().start().waitFor();
        }
        else {
            System.out.print("\033\143");
        }
    } catch (IOException | InterruptedException ex) {}
}

When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.

The iPython shell makes this easy: function? will give you the documentation. function?? shows also the code. BUT this only works for pure python functions.

Then you can always download the source code for the (c)Python.

If you're interested in pythonic implementations of core functionality have a look at PyPy source.

file:/// is a URI (Uniform Resource Identifier) that simply distinguishes from the standard URI that we all know of too well - http://.

It does imply an absolute path name pointing to the root directory in any environment, but in the context of Android, it's a convention to tell the Android run-time to say "Here, the directory www has a file called index.html located in the assets folder in the root of the project".

That is how assets are loaded at runtime, for example, a WebView widget would know exactly where to load the embedded resource file by specifying the file:/// URI.

Consider the code example:

WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/www/index.html");

A very easy mistake to make here is this, some would infer it to as file:///android_assets, notice the plural of assets in the URI and wonder why the embedded resource is not working!

You can of course make it a little more advanced. Non-blocking, writing bits and pieces, not writing the whole file at once:

var fs = require('fs');
var stream = fs.createWriteStream("my_file.txt");
stream.once('open', function(fd) {
  stream.write("My first row\n");
  stream.write("My second row\n");
  stream.end();
});

SOLUTION:

Here is the solution. Executing a function after the user has stopped typing for a specified amount of time:

var delay = (function(){
  var timer = 0;
  return function(callback, ms){
  clearTimeout (timer);
  timer = setTimeout(callback, ms);
 };
})();

Usage

$('input').keyup(function() {
  delay(function(){
    alert('Hi, func called');
  }, 1000 );
});

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

Otherwise go with inbuilt react native asynstorage

You should style for ::-ms-clear (http://msdn.microsoft.com/en-us/library/windows/apps/hh465740.aspx):

::-ms-clear {
   display: none;
}

And you also style for ::-ms-reveal pseudo-element for password field:

::-ms-reveal {
   display: none;
}

Another way to do this now that we have Java 8 lambda expressions.

arrayList.removeIf(item -> item == null || "".equals(item));

That is because you have an output:

?>
<?php

results in blank line output.

header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP

Combine all your PHP codes and make sure you don't have any spaces at the beginning of the file.

also after header('location: index.php'); add exit(); if you have any other scripts bellow.

Also move your redirect header after the last if.

If there is content, then you can also redirect by injecting javascript:

<?php
    echo "<script>window.location.href='target.php';</script>";
    exit;
?>

I think your document must be having enough space in the window to display its contents. That means there is no need to scroll down to see any more part of the document. In that case, document height would be equal to the window height.

just configure your log4j property file path in beginning of main method: e.g.: PropertyConfigurator.configure("D:\files\log4j.properties");

Inside your script file, put all of the commands within parentheses, like this:

(
echo start
ls -l
echo end
) | tee foo.log

I do this to create my own validation annotation and validator:

ValidCardType.java(annotation to put on methods/fields)

@Constraint(validatedBy = {CardTypeValidator.class})
@Documented
@Target( { ElementType.ANNOTATION_TYPE, ElementType.METHOD, ElementType.FIELD })
@Retention(RetentionPolicy.RUNTIME)
public @interface ValidCardType {
    String message() default "Incorrect card type, should be among: \"MasterCard\" | \"Visa\"";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}

And, the validator to trigger the check: CardTypeValidator.java:

public class CardTypeValidator implements ConstraintValidator<ValidCardType, String> {
    private static final String[] ALL_CARD_TYPES = {"MasterCard", "Visa"};

    @Override
    public void initialize(ValidCardType status) {
    }
    public boolean isValid(String value, ConstraintValidatorContext context) {
        return (Arrays.asList(ALL_CARD_TYPES).contains(value));
    }
}

You can do something very similar to check @NotNull.

A simple way of maintaining the aspect ratio, using the canvas element.

Try resizing the div below to see it in action.

For me, this approach worked best, so I am sharing it with others so they can benefit from it as well.

.cont {
  border: 5px solid blue;
  position: relative;
  width: 300px;
  padding: 0;
  margin: 5px;
  resize: horizontal;
  overflow: hidden;

Here's how you can do it with Java 8's Streams:

mySet.stream().sorted().collect(Collectors.toList());

or with a custom comparator:

mySet.stream().sorted(myComparator).collect(Collectors.toList());

use the full-featured .ajax jQuery function. compare with https://stackoverflow.com/a/3543713/1689451 for an example.

without testing, just merging your code with the referenced SO question:

target = $(this).attr('data-target');

$.ajax({
    url: $(this).attr('href'),
    type: "GET",
    timeout: 2000,
    success: function(response) { $(target).modal({
        show: true
    }); },
    error: function(x, t, m) {
        if(t==="timeout") {
            alert("got timeout");
        } else {
            alert(t);
        }
    }
});?

Your CustomValidator will only fire when the TextBox isn't empty.

If you need to ensure that it's not empty then you'll need a RequiredFieldValidator too.

Note: If the input control is empty, no validation functions are called and validation succeeds. Use a RequiredFieldValidator control to require the user to enter data in the input control.

EDIT:

If your CustomValidator specifies the ControlToValidate attribute (and your original example does) then your validation functions will only be called when the control isn't empty.

If you don't specify ControlToValidate then your validation functions will be called every time.

This opens up a second possible solution to the problem. Rather than using a separate RequiredFieldValidator, you could omit the ControlToValidate attribute from the CustomValidator and setup your validation functions to do something like this:

Client Side code (Javascript):

function TextBoxDCountyClient(sender, args) {
    var v = document.getElementById('<%=TextBoxDTownCity.ClientID%>').value;
    if (v == '') {
        args.IsValid = false;  // field is empty
    }
    else {
        // do your other validation tests here...
    }
}

Server side code (C#):

protected void TextBoxDTownCity_Validate(
    object source, ServerValidateEventArgs args)
{
    string v = TextBoxDTownCity.Text;
    if (v == string.Empty)
    {
        args.IsValid = false;  // field is empty
    }
    else
    {
        // do your other validation tests here...
    }
}

I am not sure if you got this resolved. To follow up on "CommonsWare's" comment.

That is not a valid string representation of a Uri. A Uri has a scheme, and "/external/images/media/470939" does not have a scheme.

Change

Uri uri=Uri.parse("/external/images/media/470939");

to

Uri uri=Uri.parse("content://external/images/media/470939");

in my case

Uri uri = Uri.parse("content://media/external/images/media/6562");

CultureInfo us = new CultureInfo("en-US");
TotalAmount.ToString("N", us)

Use DATE_FORMAT

select DATE_FORMAT(date,'%d') from tablename =>Date only

example:

select DATE_FORMAT(`date_column`,'%d') from `database_name`.`table_name`;

We are currently using mongodb as an file storage service for our collaboration over LAN. Also, projects like trello are using mongodb as their backend datastore. I have used couchdb earlier, but not in production capacity.

Something likes this

public void testPrintOut() {
    int val1 = 8;
    String val2 = "$951.23";
    String val3 = "$215.92";
    String val4 = "$198,301.22";
    System.out.println(String.format("%03d %7s %7s %11s", val1, val2, val3, val4));

    val1 = 9;
    val2 = "$950.19";
    val3 = "$216.95";
    val4 = "$198,084.26";
    System.out.println(String.format("%03d %7s %7s %11s", val1, val2, val3, val4));
}

If you are certain that you only need column A, then you can use an End function in VBA to get that result.

If all the cells A1:A100 are filled, then to select the next empty cell use:

Range("A1").End(xlDown).Offset(1, 0).Select

Here, End(xlDown) is the equivalent of selecting A1 and pressing Ctrl + Down Arrow.

If there are blank cells in A1:A100, then you need to start at the bottom and work your way up. You can do this by combining the use of Rows.Count and End(xlUp), like so:

Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Select

Going on even further, this can be generalized to selecting a range of cells, starting at a point of your choice (not just in column A). In the following code, assume you have values in cells C10:C100, with blank cells interspersed in between. You wish to select all the cells C10:C100, not knowing that the column ends at row 100, starting by manually selecting C10.

Range(Selection, Cells(Rows.Count, Selection.Column).End(xlUp)).Select

The above line is perhaps one of the more important lines to know as a VBA programmer, as it allows you to dynamically select ranges based on very few criteria, and not be bothered with blank cells in the middle.

Map is an interface in Java. And HashMap is an implementation of that interface (i.e. provides all of the methods specified in the interface).

By default , maven looks at these folders for java and test classes respectively - src/main/java and src/test/java

When the src is specified with the test classes under source and the scope for junit dependency in pom.xml is mentioned as test - org.unit will not be found by maven.

Hex -> decimal:

Convert.ToInt64(hexValue, 16);

Decimal -> Hex

string.format("{0:x}", decValue);

In today's JavaScript you can

Array.prototype.map.call('This is my string', (c) => c+c)

Obviously, c+c represents whatever you want to do with c.

This returns

["TT", "hh", "ii", "ss", " ", "ii", "ss", " ", "mm", "yy", " ", "ss", "tt", "rr", "ii", "nn", "gg"]

You could use a semaphore.

While the condition is not met, another thread acquires the semaphore.
Your thread would try to acquire it with acquireUninterruptibly()
or tryAcquire(int permits, long timeout, TimeUnit unit) and would be blocked.

When the condition is met, the semaphore is also released and your thread would acquire it.

You could also try using a SynchronousQueue or a CountDownLatch.

I like to create an easily visible object out of it like this.

Object.keys(localStorage).reduce(function(obj, str) { 
    obj[str] = localStorage.getItem(str); 
    return obj
}, {});

I do a similar thing with cookies as well.

document.cookie.split(';').reduce(function(obj, str){ 
    var s = str.split('='); 
    obj[s[0].trim()] = s[1];
    return obj;
}, {});

In my case, it was due to an IP address that Apache is listening to. Previously I have set it to 192.168.10.6 and recently Apache service is not running. I noticed that due to My laptop wifi changed recently and new IP is different. After fixing the wifi IP to laptop previous IP, Apache service is running again without any error.

Also if you don't want to change wifi IP then remove/comment that hardcode IP in httpd.conf file to resolve conflict.

It's more of an aesthetics thing, much easier to read code where you explicitly know why the loop will stop right in the declaration of the loop.

There was an competition on codechef.com (great site by the way, monthly programming competitions) where one was supposed to solve an unsolveable sudoku (one should come as close as possible with as few wrong collumns/rows/etc as possible).

What I would do, was to first generate a perfect sudoku and then override the fields, that have been given. From this pretty good basis on I used genetic programming to improve my solution.

I couldn't think of a deterministic approach in this case, because the sudoku was 300x300 and search would've taken too long.

Use WebRequest. From Scott Hanselman:

public static string HttpPost(string URI, string Parameters) 
{
   System.Net.WebRequest req = System.Net.WebRequest.Create(URI);
   req.Proxy = new System.Net.WebProxy(ProxyString, true);
   //Add these, as we're doing a POST
   req.ContentType = "application/x-www-form-urlencoded";
   req.Method = "POST";
   //We need to count how many bytes we're sending. 
   //Post'ed Faked Forms should be name=value&
   byte [] bytes = System.Text.Encoding.ASCII.GetBytes(Parameters);
   req.ContentLength = bytes.Length;
   System.IO.Stream os = req.GetRequestStream ();
   os.Write (bytes, 0, bytes.Length); //Push it out there
   os.Close ();
   System.Net.WebResponse resp = req.GetResponse();
   if (resp== null) return null;
   System.IO.StreamReader sr = 
         new System.IO.StreamReader(resp.GetResponseStream());
   return sr.ReadToEnd().Trim();
}

You can further simplify the accepted answer. Instead of typing out the enums as strings in xaml and doing more work in your converter than needed, you can explicitly pass in the enum value instead of a string representation, and as CrimsonX commented, errors get thrown at compile time rather than runtime:

ConverterParameter={x:Static local:YourEnumType.Enum1}

<StackPanel>
    <StackPanel.Resources>          
        <local:ComparisonConverter x:Key="ComparisonConverter" />          
    </StackPanel.Resources>
    <RadioButton IsChecked="{Binding Path=YourEnumProperty, Converter={StaticResource ComparisonConverter}, ConverterParameter={x:Static local:YourEnumType.Enum1}}" />
    <RadioButton IsChecked="{Binding Path=YourEnumProperty, Converter={StaticResource ComparisonConverter}, ConverterParameter={x:Static local:YourEnumType.Enum2}}" />
</StackPanel>

Then simplify the converter:

public class ComparisonConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return value?.Equals(parameter);
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return value?.Equals(true) == true ? parameter : Binding.DoNothing;
    }
}

Edit (Dec 16 '10):

Note - Multiple groups of RadioButtons in same container (Feb 17 '11):

Edit (Apr 5 '11):

Note - Enum type nested in a class (Apr 28 '11):

ConverterParameter={x:Static local:YourClass+YourNestedEnumType.Enum1}

Due to this Microsoft Connect Issue, however, the designer in VS2010 will no longer load stating "Type 'local:YourClass+YourNestedEnumType' was not found.", but the project does compile and run successfully. Of course, you can avoid this issue if you are able to move your enum type to the namespace directly.

Edit (Jan 27 '12):

public class EnumToBooleanConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return ((Enum)value).HasFlag((Enum)parameter);
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return value.Equals(true) ? parameter : Binding.DoNothing;
    }
}

Edit (May 7 '15):

    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if (value == null) {
            return false; // or return parameter.Equals(YourEnumType.SomeDefaultValue);
        }
        return value.Equals(parameter);
    }

Note - NullReferenceException (Oct 10 '18):

I believe the intent was to rename System32, but so many applications hard-coded for that path, that it wasn't feasible to remove it.

SysWoW64 wasn't intended for the dlls of 64-bit systems, it's actually something like "Windows on Windows64", meaning the bits you need to run 32bit apps on a 64bit windows.

This article explains a bit:

"Windows x64 has a directory System32 that contains 64-bit DLLs (sic!). Thus native processes with a bitness of 64 find “their” DLLs where they expect them: in the System32 folder. A second directory, SysWOW64, contains the 32-bit DLLs. The file system redirector does the magic of hiding the real System32 directory for 32-bit processes and showing SysWOW64 under the name of System32."

Edit: If you're talking about an installer, you really should not hard-code the path to the system folder. Instead, let Windows take care of it for you based on whether or not your installer is running on the emulation layer.

All the answers suggesting a permanent change have the same problem: They break the path registry value.

SetEnvironmentVariable turns the REG_EXPAND_SZ value %SystemRoot%\system32 into a REG_SZ value of C:\Windows\system32.

Any other variables in the path are lost as well. Adding new ones using %myNewPath% won't work any more.

Here's a script Set-PathVariable.ps1 that I use to address this problem:

 [CmdletBinding(SupportsShouldProcess=$true)]
 param(
     [parameter(Mandatory=$true)]
     [string]$NewLocation)

     $regPath = "SYSTEM\CurrentControlSet\Control\Session Manager\Environment"

     {
         $regKey = $hklm.OpenSubKey($regPath, $FALSE)
         $envpath = $regKey.GetValue("Path", "", [Microsoft.Win32.RegistryValueOptions]::DoNotExpandEnvironmentNames)
         return $envPath
     }
 }

 Process
 {
     # Win32API error codes
     $ERROR_SUCCESS = 0
     $ERROR_DUP_NAME = 34
     $ERROR_INVALID_DATA = 13

     $NewLocation = $NewLocation.Trim();

     If ($NewLocation -eq "" -or $NewLocation -eq $null)
     {
         Exit $ERROR_INVALID_DATA
     }

     [string]$oldPath = GetOldPath
     Write-Verbose "Old Path: $oldPath"

     # Check whether the new location is already in the path
     $parts = $oldPath.split(";")
     If ($parts -contains $NewLocation)
     {
         Write-Warning "The new location is already in the path"
         Exit $ERROR_DUP_NAME
     }

     # Build the new path, make sure we don't have double semicolons
     $newPath = $oldPath + ";" + $NewLocation
     $newPath = $newPath -replace ";;",""

     if ($pscmdlet.ShouldProcess("%Path%", "Add $NewLocation")){

         # Add to the current session
         $env:path += ";$NewLocation"

         # Save into registry
         $regKey = $hklm.OpenSubKey($regPath, $True)
         $regKey.SetValue("Path", $newPath, [Microsoft.Win32.RegistryValueKind]::ExpandString)
         Write-Output "The operation completed successfully."
     }

     Exit $ERROR_SUCCESS
 }

I explain the problem in more detail in a blog post.

I use strrchr(). For instance to find the extension of a file I use this function:

$string = 'filename.jpg';
$extension = strrchr( $string, '.'); //returns ".jpg"

unfortunately, with "mvim -v", ALT plus arrow windows still does not work. I have not found any way to enable it :-(

The modern way to do this is with flexbox, adding align-items: flex-end; on the container.

With this content:

<div class="Container">
  <div>one</div>
  <div>two</div>
</div>

Use this style:

.Container {
  display: flex;
  align-items: flex-end;
}

You definitely can achieve that with nbconvert using the following command:

jupyter nbconvert --to python while.ipynb 

However, having used it personally I would advise against it for several reasons:

1. It's one thing to be able to convert to simple Python code and another to have all the right abstractions, classes access and methods set up. If the whole point of you converting your notebook code to Python is getting to a state where your code and notebooks are maintainable for the long run, then nbconvert alone will not suffice. The only way to do that is by manually going through the codebase.
2. Notebooks inherently promote writing code which is not maintainable (https://docs.google.com/presentation/d/1n2RlMdmv1p25Xy5thJUhkKGvjtV-dkAIsUXP-AL4ffI/edit#slide=id.g3d7fe085e7_0_21). Using nbconvert on top might just prove to be a bandaid. Specific examples of where it promotes not-so-maintainable code are imports might be sprayed throughout, hard coded paths are not in one simple place to view, class abstractions might not be present, etc.
3. nbconvert still mixes execution code and library code.
4. Comments are still not present (probably were not in the notebook).
5. There is still a lack of unit tests etc.

So to summarize, there is not good way to out of the box convert python notebooks to maintainable, robust python modularized code, the only way is to manually do surgery.

The dropdown list appearing like that depends on what your browser is, as it is not possible to style this away for some. It looks like yours is IE9, but would look quite different in Chrome.

You could look to use something like this:

http://silviomoreto.github.io/bootstrap-select/

Which will make your selectboxes more consistent cross browser.

In addition to checking your table setup to confirm that the field is set to NOT NULL with a default of CURRENT_TIMESTAMP, you can insert date/time values from PHP by writing them in a string format compatible with MySQL.

 $timestamp = date("Y-m-d H:i:s");

This will give you the current date and time in a string format that you can insert into MySQL.

to_char(mydate, 'MONTH') will do the job.

Combining much of above here is my real practical example, selecting records based on both meterid & timestamp. I have needed this command for years. Executes really quickly.

mysqldump -uuser -ppassword main_dbo trHourly --where="MeterID =5406 AND TIMESTAMP<'2014-10-13 05:00:00'" --no-create-info --skip-extended-insert | grep  '^INSERT' > 5406.sql

I updated jsch lib latest one (0.1.55). working fine for me. no need to restart the server or no need to update java(current using java8)

It can be treated as defensive programming approach from the compiler - the variables must be assigned before it can be used.

For me it helped to add ?$query_string at the end of /index.php, like below:

location / {
        try_files $uri $uri/ /index.php?$query_string;
}

I wrote some test code to check JQueryUI drag/drop. The example shows how to drag an element from a container and drop it to another container.

I'm finding BigNumber.js meets my needs.

A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic.

It has good documentation and the author is very diligent responding to feedback.

The same author has 2 other similar libraries:

Big.js

A small, fast JavaScript library for arbitrary-precision decimal arithmetic. The little sister to bignumber.js.

and Decimal.js

An arbitrary-precision Decimal type for JavaScript.

Here's some code using BigNumber:

$(function(){_x000D_
_x000D_
  _x000D_
  var product = BigNumber(.1).times(.2);  _x000D_
  $('#product').text(product);_x000D_
_x000D_
  var sum = BigNumber(.1).plus(.2);  _x000D_
  $('#sum').text(sum);_x000D_
_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<!-- 1.4.1 is not the current version, but works for this example. -->_x000D_

You can use the Conditional Formatting to replace text and NOT effect any formulas. Simply go to the Rule's format where you will see Number, Font, Border and Fill.
Go to the Number tab and select CUSTOM. Then simply type where it says TYPE: what you want to say in QUOTES.

Example.. "OTHER"

Use unlist with use.names = FALSE argument.

unlist(myList, use.names=FALSE)

if you know the remote branch you want to check, you can find out the latest via:

Classes are like categories. Many HTML elements can belong to a class, and an HTML element can have more than one class. Classes are used to apply general styles or styles that can be applied across multiple HTML elements.

IDs are identifiers. They're unique; no one else is allowed to have that same ID. IDs are used to apply unique styles to an HTML element.

I use IDs and classes in this fashion:

<div id="header">
  <h1>I am a header!</h1>
  <p>I am subtext for a header!</p>
</div>
<div id="content">
  <div class="section">
    <p>I am a section!</p>
  </div>
  <div class="section special">
    <p>I am a section!</p>
  </div>
  <div class="section">
    <p>I am a section!</p>
  </div>
</div>

In this example, the header and content sections can be styled via #header and #content. Each section of the content can be applied a common style through #content .section. Just for kicks, I added a "special" class for the middle section. Suppose you wanted a particular section to have a special styling. This can be achieved with the .special class, yet the section still inherits the common styles from #content .section.

When I do JavaScript or CSS development, I typically use IDs to access/manipulate a very specific HTML element, and I use classes to access/apply styles to a broad range of elements.

You can create a generic style and re-use it on multiple textviews like the one below:

textView.setTextAppearance(this, R.style.MyTextStyle);

Edit: this refers to Context

Here is how you can scale it easily.

This works in 2.x with the Simulator and the iPhone.

UIImage *thumbnail = [originalImage _imageScaledToSize:CGSizeMake(40.0, 40.0) interpolationQuality:1];

It's an abbreviation of Error NO ENTry (or Error NO ENTity), and can actually be used for more than files/directories.

It's abbreviated because C compilers at the dawn of time didn't support more than 8 characters in symbols.

Just in case someone is looking for user Display Name as opposed to User Name, like me.

Here's the treat :

System.DirectoryServices.AccountManagement.UserPrincipal.Current.DisplayName.

Add Reference to System.DirectoryServices.AccountManagement in your project.

This answer is based on user3715338's answer (with a small spelling error corrected) and mixed with Michael's answer for Hibernate 3.6 - based on the accepted answer from Brian Deterling. I then extended it (for PostgreSQL) with a couple more types replacing the questionmarks:

public static String toSql(Criteria criteria)
{
    String sql = "";
    Object[] parameters = null;
    try
    {
        CriteriaImpl criteriaImpl = (CriteriaImpl) criteria;
        SessionImpl sessionImpl = (SessionImpl) criteriaImpl.getSession();
        SessionFactoryImplementor factory = sessionImpl.getSessionFactory();
        String[] implementors = factory.getImplementors(criteriaImpl.getEntityOrClassName());
        OuterJoinLoadable persister = (OuterJoinLoadable) factory.getEntityPersister(implementors[0]);
        LoadQueryInfluencers loadQueryInfluencers = new LoadQueryInfluencers();
        CriteriaLoader loader = new CriteriaLoader(persister, factory,
            criteriaImpl, implementors[0].toString(), loadQueryInfluencers);
        Field f = OuterJoinLoader.class.getDeclaredField("sql");
        f.setAccessible(true);
        sql = (String) f.get(loader);
        Field fp = CriteriaLoader.class.getDeclaredField("translator");
        fp.setAccessible(true);
        CriteriaQueryTranslator translator = (CriteriaQueryTranslator) fp.get(loader);
        parameters = translator.getQueryParameters().getPositionalParameterValues();
    }
    catch (Exception e)
    {
        throw new RuntimeException(e);
    }
    if (sql != null)
    {
        int fromPosition = sql.indexOf(" from ");
        sql = "\nSELECT * " + sql.substring(fromPosition);

        if (parameters != null && parameters.length > 0)
        {
            for (Object val : parameters)
            {
                String value = "%";
                if (val instanceof Boolean)
                {
                    value = ((Boolean) val) ? "1" : "0";
                }
                else if (val instanceof String)
                {
                    value = "'" + val + "'";
                }
                else if (val instanceof Number)
                {
                    value = val.toString();
                }
                else if (val instanceof Class)
                {
                    value = "'" + ((Class) val).getCanonicalName() + "'";
                }
                else if (val instanceof Date)
                {
                    SimpleDateFormat sdf = new SimpleDateFormat(
                        "yyyy-MM-dd HH:mm:ss.SSS");
                    value = "'" + sdf.format((Date) val) + "'";
                }
                else if (val instanceof Enum)
                {
                    value = "" + ((Enum) val).ordinal();
                }
                else
                {
                    value = val.toString();
                }
                sql = sql.replaceFirst("\\?", value);
            }
        }
    }
    return sql.replaceAll("left outer join", "\nleft outer join").replaceAll(
        " and ", "\nand ").replaceAll(" on ", "\non ").replaceAll("<>",
        "!=").replaceAll("<", " < ").replaceAll(">", " > ");
}

Also this is an example of how to print List of List using advanced for loop:

public static void main(String[] args){
        int[] a={1,3, 7, 8, 3, 9, 2, 4, 10};
        List<List<Integer>> triplets;
        triplets=sumOfThreeNaive(a, 13);
        for (List<Integer> list : triplets){
            for (int triplet: list){
                System.out.print(triplet+" ");
            }
            System.out.println();
        }
    }

The first thing to consider is that it is rare that you would only want to check whether or not a file exists. In most situations, you're trying to do something with the file if it exists. In Go, any time you try to perform some operation on a file that doesn't exist, the result should be a specific error (os.ErrNotExist) and the best thing to do is check whether the return err value (e.g. when calling a function like os.OpenFile(...)) is os.ErrNotExist.

The recommended way to do this used to be:

file, err := os.OpenFile(...)
if os.IsNotExist(err) {
    // handle the case where the file doesn't exist
}

However, since the addition of errors.Is in Go 1.13 (released in late 2019), the new recommendation is to use errors.Is:

file, err := os.OpenFile(...)
if errors.Is(err, os.ErrNotExist) {
    // handle the case where the file doesn't exist
}

It's usually best to avoid using os.Stat to check for the existence of a file before you attempt to do something with it, because it will always be possible for the file to be renamed, deleted, etc. in the window of time before you do something with it.

However, if you're OK with this caveat and you really, truly just want to check whether a file exists without then proceeding to do something useful with it (as a contrived example, let's say that you're writing a pointless CLI tool that tells you whether or not a file exists and then exits ¯\_(?)_/¯), then the recommended way to do it would be:

if _, err := os.Stat(filename); errors.Is(err, os.ErrNotExist) {
    // file does not exist
} else {
    // file exists
}

The Facebook API limit isn't really documented, but apparently it's something like: 600 calls per 600 seconds, per token & per IP. As the site is restricted, quoting the relevant part:

After some testing and discussion with the Facebook platform team, there is no official limit I'm aware of or can find in the documentation. However, I've found 600 calls per 600 seconds, per token & per IP to be about where they stop you. I've also seen some application based rate limiting but don't have any numbers.

As a general rule, one call per second should not get rate limited. On the surface this seems very restrictive but remember you can batch certain calls and use the subscription API to get changes.

As you can access the Graph API on the client side via the Javascript SDK; I think if you travel your request for photos from the client, you won't hit any application limit as it's the user (each one with unique id) who's fetching data, not your application server (unique ID).

This may mean a huge refactor if everything you do go through a server. But it seems like the best solution if you have so many request (as it'll give a breath to your server).

Else, you can try batch request, but I guess you're already going this way if you have big traffic.

If nothing of this works, according to the Facebook Platform Policy you should contact them.

If you exceed, or plan to exceed, any of the following thresholds please contact us as you may be subject to additional terms: (>5M MAU) or (>100M API calls per day) or (>50M impressions per day).

This isn't exactly what you're looking for, but it would automatically select the "active" file in the Solution Explorer:

Tools-->Options-->Projects and Solutions-->Track Active Item in Solution Explorer.

One quick comment to user306253's answer: caution with this, when you try to load something in the UIWebView yourself (i.e. even from the code), this method will prevent it to happened.

What you can do to prevent this (thanks Wade) is:

if (inType == UIWebViewNavigationTypeLinkClicked) {
    [[UIApplication sharedApplication] openURL:[inRequest URL]];
    return NO;
}

return YES;

You might also want to handle the UIWebViewNavigationTypeFormSubmitted and UIWebViewNavigationTypeFormResubmitted types.
