In JUnit 4, another option for you may be to create an annotation to denote that the test needs to meet your custom criteria, then extend the default runner with your own and using reflection, base your decision on the custom criteria. It may look something like this:

public class CustomRunner extends BlockJUnit4ClassRunner {
    public CTRunner(Class<?> klass) throws initializationError {
        super(klass);
    }

    @Override
    protected boolean isIgnored(FrameworkMethod child) {
        if(shouldIgnore()) {
            return true;
        }
        return super.isIgnored(child);
    }

    private boolean shouldIgnore(class) {
        /* some custom criteria */
    }
}

You have to install git-extras for this. You can install it in Ubuntu using apt-get,

$ sudo apt-get install git-extras

Then you can use the git ignore command.

$ git ignore file_name

Adding to Greg Hewgill answer (of using core.fileMode config variable):

You can use --chmod=(-|+)x option of git update-index (low-level version of "git add") to change execute permissions in the index, from where it would be picked up if you use "git commit" (and not "git commit -a").

For end of line use:

git diff --ignore-space-at-eol

Instead of what are you using currently:

git diff -w (--ignore-all-space)

For start of line... you are out of luck if you want a built in solution.

However, if you don't mind getting your hands dirty there's a rather old patch floating out there somewhere that adds support for "--ignore-space-at-sol".

If your repo doesn't already have a .gitignore file, then a simple solution is to create a .gitignore file, and in it add .gitignore to the list of files to be ignored.

Docker Solution

• Disable ALL warnings before running the python application
  • You can disable your dockerized tests as well

ENV PYTHONWARNINGS="ignore::DeprecationWarning"

In linux you can use this commande :

for exemple i want to delete "*.py~" so my command should be ==>

find . -name "*.py~" -exec rm -f {} \;

Ignore is exactly what the name implies.

It doesn't "throw away" something you don't need instead, it ignores the amount of characters you specify when you call it, up to the char you specify as a breakpoint.

It works with both input and output buffers.

Essentially, for std::cin statements you use ignore before you do a getline call, because when a user inputs something with std::cin, they hit enter and a '\n' char gets into the cin buffer. Then if you use getline, it gets the newline char instead of the string you want. So you do a std::cin.ignore(1000,'\n') and that should clear the buffer up to the string that you want. (The 1000 is put there to skip over a specific amount of chars before the specified break point, in this case, the \n newline character.)

For ignoring subfolders but not main folder I could only get this to work in Visual Studio Code by placing a dummy readme.txt in the main folder. Only then /*/ checked in the main folder (and no subfolders).

You could use .gitignore to keep the config.xml out of the repository, and then use a post commit hook to upload the appropriate config.xml file to the server.

The name of the swap file is normally the same as the file you are editing, with the extension ".swp".

• On Unix, a '.' is prepended to swap file names in the same directory as the edited file. This avoids that the swap file shows up in a directory listing.
• On MS-DOS machines and when the 'shortname' option is on, any '.' in the original file name is replaced with '_'.
• If this file already exists (e.g., when you are recovering from a crash) a warning is given and another extension is used, ".swo", ".swn", etc.
• An existing file will never be overwritten.
• The swap file is deleted as soon as Vim stops editing the file.

The replacement of '.' with '_' is done to avoid problems with MS-DOS compatible filesystems (e.g., crossdos, multidos).

While generally correct your solution does not work in all circumstances. Assume a repo dir like this:

# ls **/*                                                                                                       
doc/index.html  README.txt  tmp/dir0/file0  tmp/file1  tmp/file2

doc:
index.html

tmp:
dir0  file1  file2

tmp/dir0:
file0

and a .gitignore like this:

# cat .gitignore
doc
tmp/*

This ignores the doc directory and all files below tmp. Git works as expected, but the given command for listing the ignored files does not. Lets have a look at what git has to say:

# git ls-files --others --ignored --exclude-standard                                                            
tmp/file1
tmp/file2

Notice that doc is missing from the listing. You can get it with:

# git ls-files --others --ignored --exclude-standard --directory                                                
doc/

Notice the additional --directory option.

From my knowledge there is no one command to list all ignored files at once. But I don't know why tmp/dir0 does not show up at all.

I think if you need to develop something quick with no Strange things in the middle, and you need the facility to have entities representing your tables:

Linq2Sql can be a good allied, using it with LinQ unleashes a great developing timing.

MSK,

Have you tried setting a namespace declaration to your member variables like this? :

@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;

@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;

For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.

I have also used following link as others have suggested you for bluetooth communication.

http://developer.android.com/guide/topics/connectivity/bluetooth.html

The thing is all you need is a class BluetoothChatService.java

this class has following threads:

1. Accept
2. Connecting
3. Connected

Now when you call start function of the BluetoothChatService like:

mChatService.start();

It starts accept thread which means it will start looking for connection.

Now when you call

mChatService.connect(<deviceObject>,false/true);

Here first argument is device object that you can get from paired devices list or when you scan for devices you will get all the devices in range you can pass that object to this function and 2nd argument is a boolean to make secure or insecure connection.

connect function will start connecting thread which will look for any device which is running accept thread.

When such a device is found both accept thread and connecting thread will call connected function in BluetoothChatService:

connected(mmSocket, mmDevice, mSocketType);

this method starts connected thread in both the devices: Using this socket object connected thread obtains the input and output stream to the other device. And calls read function on inputstream in a while loop so that it's always trying read from other device so that whenever other device send a message this read function returns that message.

BluetoothChatService also has a write method which takes byte[] as input and calls write method on connected thread.

mChatService.write("your message".getByte());

write method in connected thread just write this byte data to outputsream of the other device.

public void write(byte[] buffer) {
   try {
       mmOutStream.write(buffer);
    // Share the sent message back to the UI Activity
    // mHandler.obtainMessage(
    // BluetoothGameSetupActivity.MESSAGE_WRITE, -1, -1,
    // buffer).sendToTarget();
    } catch (IOException e) {
    Log.e(TAG, "Exception during write", e);
     }
}

Now to communicate between two devices just call write function on mChatService and handle the message that you will receive on the other device.

I think you need a service that handle the authentication process (and its storage).

In this service you'll need some basic methods :

• isAuthenticated()
• login()
• logout()
• etc ...

This service should be injected in your controllers of each module :

• In your dashboard section, use this service to check if user is authenticated (service.isAuthenticated() method) . if not, redirect to /login
• In your login section, just use the form data to authenticate the user through your service.login() method

A good and robust example for this behavior is the project angular-app and specifically its security module which is based over the awesome HTTP Auth Interceptor Module

Hope this helps

This is one of those things that can be difficult to search for if you don't already know where to look.

[ is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.

There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.

[ is equivalent to the test command, except that [ requires ] as its last argument, and test does not.

Assuming the bash documentation is installed on your system, if you type info bash and search for 'test' or '[' (the apostrophes are part of the search), you'll find the documentation for the [ command, also known as the test command. If you use man bash instead of info bash, search for ^ *test (the word test at the beginning of a line, following some number of spaces).

Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, != is the string inequality operator.

You can also find bash documentation on the web.

• Bash reference
• Bourne shell builtins (including test and [)
• Bash Conditional Expressions -- (Scroll to the bottom; -ne is under "arg1 OP arg2")
• POSIX documentation for test

The official definition of the test command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).

You have to modify the php.ini files in your xampp folder. Three files in three different places need to be changed.

Follow the following steps to enable curl library with XAMPP in Windows:

Step 1:

Browse and open the following 3 files

C:\Program Files\xampp\apache\bin\php.ini
C:\Program Files\xampp\php\php.ini
C:\Program Files\xampp\php\php4\php.ini

Step 2:

Uncomment the following line in your php.ini file by removing the semicolon (;).

;extension=php_curl.dll

After that it will look something like something below-

extension=php_curl.dll

Step 3:

Restart your Apache server.

Step 4:

Check your phpinfo() to see whether curl has properly enabled or not.

Enjoy using curl() library.

I have Written a small script to download the live youtube video, you may use as single command as well. script it can be invoked simply as,

~/ytdl_lv.sh <URL> <output file name>

e.g.

~/ytdl_lv.sh https://www.youtube.com/watch?v=BLIGxsYLyjc myfile.mp4

script is as simple as below,

#!/bin/bash 

# ytdl_lv.sh
# Author Prashant
# 

URL=$1 
OUTNAME=$2
streamlink --hls-live-restart -o ${OUTNAME} ${URL} best

here the best is the stream quality, it also can be 144p (worst), 240p, 360p, 480p, 720p (best)

You should also ensure you set a reference to WindowsBase. This is required to use the SDK as it handles System.IO.Packaging (which is used for unzipping and opening the compressed .docx/.xlsx/.pptx as an OPC document).

I have used the same instructions Stefan used, taken from Tortoise website.

But it's important to click COMMIT right after. I was getting crazy until I realized that.

If you need to make an older revision your head revision do the following:

1. Select the file or folder in which you need to revert the changes. If you want to revert all changes, this should be the top level folder.

2. Select TortoiseSVN ? Show Log to display a list of revisions. You may need to use Show All or Next 100 to show the revision(s) you are interested in.

3. Right click on the selected revision, then select Context Menu ? Revert to this revision. This will discard all changes after the selected revision.

4. Make a commit.

You need to declare @font-face like this in your stylesheet

@font-face {
  font-family: 'Awesome-Font';
  font-style: normal;
  font-weight: 400;
  src: local('Awesome-Font'), local('Awesome-Font-Regular'), url(path/Awesome-Font.woff) format('woff');
}

Now if you want to apply this font to a paragraph simply use it like this..

p {
font-family: 'Awesome-Font', Arial;
}

Using a decorator for measuring execution time for functions can be handy. There is an example at http://www.zopyx.com/blog/a-python-decorator-for-measuring-the-execution-time-of-methods.

Below I've shamelessly pasted the code from the site mentioned above so that the example exists at SO in case the site is wiped off the net.

import time                                                

def timeit(method):

    def timed(*args, **kw):
        ts = time.time()
        result = method(*args, **kw)
        te = time.time()

        print '%r (%r, %r) %2.2f sec' % \
              (method.__name__, args, kw, te-ts)
        return result

    return timed

class Foo(object):

    @timeit
    def foo(self, a=2, b=3):
        time.sleep(0.2)

@timeit
def f1():
    time.sleep(1)
    print 'f1'

@timeit
def f2(a):
    time.sleep(2)
    print 'f2',a

@timeit
def f3(a, *args, **kw):
    time.sleep(0.3)
    print 'f3', args, kw

f1()
f2(42)
f3(42, 43, foo=2)
Foo().foo()

ctrl != super on windows and linux machines.

If the F12 version of "Goto Definition" produces results of several files, the "ctrl + shift + click" version might not work well. I found that bug when viewing golang project with GoSublime package.

Example Code

public class Person {
    public String firstName { get; set; }
    public String lastName { get; set; }
}

// Instantiate Person
var person = new Person { firstName = "Albert", lastName = "Einstein" };

// We can print fullname of the above person as follows
Console.WriteLine("Full-Name - " + person.firstName + " " + person.lastName);
Console.WriteLine("Full-Name - {0} {1}", person.firstName, person.lastName);
Console.WriteLine($"Full-Name - {person.firstName} {person.lastName}");

Output

Full-Name - Albert Einstein
Full-Name - Albert Einstein
Full-Name - Albert Einstein

It is Interpolated Strings. You can use an interpolated string anywhere you can use a string literal. When running your program would execute the code with the interpolated string literal, the code computes a new string literal by evaluating the interpolation expressions. This computation occurs each time the code with the interpolated string executes.

Following example produces a string value where all the string interpolation values have been computed. It is the final result and has type string. All occurrences of double curly braces (“{{“ and “}}”) are converted to a single curly brace.

string text = "World";
var message = $"Hello, {text}";

After executing above 2 lines, variable message contains "Hello, World".

Console.WriteLine(message); // Prints Hello, World

The model has a save method, which saves all the details necessary to reconstitute the model. An example from the keras documentation:

from keras.models import load_model

model.save('my_model.h5')  # creates a HDF5 file 'my_model.h5'
del model  # deletes the existing model

# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')

Maybe this will help:

<select onchange="location = this.value;">
 <option value="home.html">Home</option>
 <option value="contact.html">Contact</option>
 <option value="about.html">About</option>
</select>

Yes, it's "not equal".

I think what you are looking for is:

list(im.getdata())

or, if the image is too big to load entirely into memory, so something like that:

for pixel in iter(im.getdata()):
    print pixel

from PIL documentation:

getdata

im.getdata() => sequence

Returns the contents of an image as a sequence object containing pixel values. The sequence object is flattened, so that values for line one follow directly after the values of line zero, and so on.

Note that the sequence object returned by this method is an internal PIL data type, which only supports certain sequence operations, including iteration and basic sequence access. To convert it to an ordinary sequence (e.g. for printing), use list(im.getdata()).

If you're using GNU find,

find . -mtime 1 -exec cp -t ~/test/ {} +

This works as well as piping the output into xargs while avoiding the pitfalls of doing so (it handles embedded spaces and newlines without having to use find ... -print0 | xargs -0 ...).

A little late to the party, but this is how I did it for an insert:

DECLARE @ManagerID AS Varchar (25) = 'NA'
DECLARE @ManagerEmail AS Varchar (50) = 'NA'
Declare @RecordCount AS int = 0

SET @ManagerID = ?
SET @ManagerEmail = ?
SET @RecordCount = ?

INSERT INTO...

I figured it out!

With almost 2 hours worth of trial and error, i figured it out.

This WORKS and is what you do to pass variables to remote job:

    def handle = triggerRemoteJob(remoteJenkinsName: 'remoteJenkins', job: 'RemoteJob' paramters: "param1=${env.PARAM1}\nparam2=${env.param2}")

Use \n to separate two parameters, no spaces..

As opposed to parameters: '''someparams'''

we use paramters: "someparams"

the " ... " is what gets us the values of the desired variables. (These are double quotes, not two single quotes)

the ''' ... ''' or ' ... ' will not get us those values. (Three single quotes or just single quotes)

All parameters here are defined in environment{} block at the start of the pipeline and are modified in stages>steps>scripts wherever necessary.

I also tested and found that when you use " ... " you cannot use something like ''' ... "..." ''' or "... '..'..." or any combination of it...

The catch here is that when you are using "..." in parameters section, you cannot pass a string parameter; for example This WILL NOT WORK:

    def handle = triggerRemoteJob(remoteJenkinsName: 'remoteJenkins', job: 'RemoteJob' paramters: "param1=${env.PARAM1}\nparam2='param2'")

if you want to pass something like the one above, you will need to set an environment variable param2='param2' and then use ${env.param2} in the parameters section of remote trigger plugin step

While other answers provide detailed solutions for various setups, this might help someone who is just looking for a general answer.

There are three general options, pick one or more:

1. On the client side, delete the cookie from the browser using javascript.

2. On the server side, set the cookie value to an empty string or something useless (for example "deleted"), and set the cookie expiration time to a time in the past.

3. On the server side, update the refreshtoken stored in your database. Use this option to log out the user from all devices where they are logged in (their refreshtokens will become invalid and they have to log in again).

This works perfectly

the name "row.names" or the number 0 specifies the row names.

Unfortunately, it seems that proxy information must be set on each call to http.request. Node does not include a mechanism for global proxy settings.

The global-tunnel-ng module on NPM appears to handle this, however:

var globalTunnel = require('global-tunnel-ng');

globalTunnel.initialize({
  host: '10.0.0.10',
  port: 8080,
  proxyAuth: 'userId:password', // optional authentication
  sockets: 50 // optional pool size for each http and https
});

After the global settings are establish with a call to initialize, both http.request and the request library will use the proxy information.

The module can also use the http_proxy environment variable:

process.env.http_proxy = 'http://proxy.example.com:3129';
globalTunnel.initialize();

JSON regulates key type to be string. The purpose is to support the dot notation to access the members of the object.

For example, person = {"height":170, "weight":60, "age":32}. You can access members by person.height, person.weight, etc. If JSON supports value keys, then it would look like person.0, person.1, person.2.

I had the same issue recently.

It means that the port is already being used by another application (express or other software)

In my case, I had accidentally run express on 2 terminals, so exiting the terminal using 'Ctrl + C' fixed things for me. (Run server from only one terminal)

Hope it helps others.

Look at rsync based Windows tool NASBackup. It will be a bonus if you are acquainted with rsync commands.

macOS & Linux

BSD's find implementation on macOS is different from GNU find - this is compatible with both BSD and GNU find. Start with a globbing implementation, using -name and the -o for or - Put this function in your .bashrc file:

pyclean () {
    find . -type f -name '*.py[co]' -delete -o -type d -name __pycache__ -delete
}

Then cd to the directory you want to recursively clean, and type pyclean.

GNU find-only

This is a GNU find, only (i.e. Linux) solution, but I feel it's a little nicer with the regex:

pyclean () {
    find . -regex '^.*\(__pycache__\|\.py[co]\)$' -delete
}

Any platform, using Python 3

On Windows, you probably don't even have find. You do, however, probably have Python 3, which starting in 3.4 has the convenient pathlib module:

python3 -Bc "import pathlib; [p.unlink() for p in pathlib.Path('.').rglob('*.py[co]')]"
python3 -Bc "import pathlib; [p.rmdir() for p in pathlib.Path('.').rglob('__pycache__')]"

The -B flag tells Python not to write .pyc files. (See also the PYTHONDONTWRITEBYTECODE environment variable.)

The above abuses list comprehensions for looping, but when using python -c, style is rather a secondary concern. Alternatively we could abuse (for example) __import__:

python3 -Bc "for p in __import__('pathlib').Path('.').rglob('*.py[co]'): p.unlink()"
python3 -Bc "for p in __import__('pathlib').Path('.').rglob('__pycache__'): p.rmdir()"

Critique of an answer

The top answer used to say:

find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf

This would seem to be less efficient because it uses three processes. find takes a regular expression, so we don't need a separate invocation of grep. Similarly, it has -delete, so we don't need a separate invocation of rm —and contrary to a comment here, it will delete non-empty directories so long as they get emptied by virtue of the regular expression match.

From the xargs man page:

find /tmp -depth -name core -type f -delete

Find files named core in or below the directory /tmp and delete them, but more efficiently than in the previous example (because we avoid the need to use fork(2) and exec(2) to launch rm and we don't need the extra xargs process).

The pyplot functions you are calling, axhline() and axvline() draw lines that span a portion of the axis range, regardless of coordinates. The parameters xmin or ymin use value 0.0 as the minimum of the axis and 1.0 as the maximum of the axis.

Instead, use plt.plot((x1, x2), (y1, y2), 'k-') to draw a line from the point (x1, y1) to the point (x2, y2) in color k. See pyplot.plot.

A static variable can get an initial value only one time. This means that if you have code such as "static int a=0" in a sample function, and this code is executed in a first call of this function, but not executed in a subsequent call of the function; variable (a) will still have its current value (for example, a current value of 5), because the static variable gets an initial value only one time.

A constant variable has its value constant in whole of the code. For example, if you set the constant variable like "const int a=5", then this value for "a" will be constant in whole of your program.

I would use Celery to handle the asynchronous task for you. You'll need to install a broker to serve as your task queue (RabbitMQ and Redis are recommended).

app.py:

from flask import Flask
from celery import Celery

broker_url = 'amqp://guest@localhost'          # Broker URL for RabbitMQ task queue

app = Flask(__name__)    
celery = Celery(app.name, broker=broker_url)
celery.config_from_object('celeryconfig')      # Your celery configurations in a celeryconfig.py

@celery.task(bind=True)
def some_long_task(self, x, y):
    # Do some long task
    ...

@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
    ...
    data = json.loads(request.data)
    text_list = data.get('text_list')
    final_file = audio_class.render_audio(data=text_list)
    some_long_task.delay(x, y)                 # Call your async task and pass whatever necessary variables
    return Response(
        mimetype='application/json',
        status=200
    )

Run your Flask app, and start another process to run your celery worker.

$ celery worker -A app.celery --loglevel=debug

I would also refer to Miguel Gringberg's write up for a more in depth guide to using Celery with Flask.

Wget currently only supports x-www-form-urlencoded data. --post-file is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example.

--post-data and --post-file work the same way: the only difference is that --post-data allows you to specify the data in the command line, while --post-file allows you to specify the path of the file that contain the data to send.

Here's the documentation:

 --post-data=string
       --post-file=file
           Use POST as the method for all HTTP requests and send the specified data
           in the request body.  --post-data sends string as data, whereas
           --post-file sends the contents of file.  Other than that, they work in
           exactly the same way. In particular, they both expect content of the
           form "key1=value1&key2=value2", with percent-encoding for special
           characters; the only difference is that one expects its content as a
           command-line parameter and the other accepts its content from a file. In
           particular, --post-file is not for transmitting files as form
           attachments: those must appear as "key=value" data (with appropriate
           percent-coding) just like everything else. Wget does not currently
           support "multipart/form-data" for transmitting POST data; only
           "application/x-www-form-urlencoded". Only one of --post-data and
           --post-file should be specified.

Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.

Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN.

wget --post-data 'user=foo&password=bar' http://example.com/auth.php

Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

Postgres process query different from other RDMS. Put schema name in double quote before your table name like this, "SCHEMA_NAME"."SF_Bands"

I coded a C# version based on JAVA ANPR, but I changed the awt library functions with OpenCV. You can check it at http://anprmx.codeplex.com

another way would be to use dplyr package:

x = c(1,1,2,3,4,4,4)
dplyr::distinct(as.data.frame(x))

You can use a combination of pwd and basename. E.g.

#!/bin/bash

CURRENT=`pwd`
BASENAME=`basename "$CURRENT"`

echo "$BASENAME"

exit;

Try:

var selectedVal;

for( i = 0; i < document.form_name.gender.length; i++ )
{
  if(document.form_name.gender[i].checked)
    selectedVal = document.form_name.gender[i].value; //male or female
    break;
  }
}

Another solution:

If you have a static subclass in a non-static outer class, you can access the resources from within the subclass via static variables in the outer class, which you initialise on creation of the outer class. Like

public class Outerclass {

    static String resource1

    public onCreate() {
        resource1 = getString(R.string.text);
    }

    public static class Innerclass {

        public StringGetter (int num) {
            return resource1; 
        }
    }
}

I used it for the getPageTitle(int position) Function of the static FragmentPagerAdapter within my FragmentActivity which is useful because of I8N.

In one of my jobs in the early 90's, we used .cc and .hh for source and header files respectively. I still prefer it over all the alternatives, probably because it's easiest to type.

If you want this to be handled by UILabel and not UITextView, you can make UILabel subclass, like this one:

class LinkedLabel: UILabel {

fileprivate let layoutManager = NSLayoutManager()
fileprivate let textContainer = NSTextContainer(size: CGSize.zero)
fileprivate var textStorage: NSTextStorage?


override init(frame aRect:CGRect){
    super.init(frame: aRect)
    self.initialize()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    self.initialize()
}

func initialize(){

    let tap = UITapGestureRecognizer(target: self, action: #selector(LinkedLabel.handleTapOnLabel))
    self.isUserInteractionEnabled = true
    self.addGestureRecognizer(tap)
}

override var attributedText: NSAttributedString?{
    didSet{
        if let _attributedText = attributedText{
            self.textStorage = NSTextStorage(attributedString: _attributedText)

            self.layoutManager.addTextContainer(self.textContainer)
            self.textStorage?.addLayoutManager(self.layoutManager)

            self.textContainer.lineFragmentPadding = 0.0;
            self.textContainer.lineBreakMode = self.lineBreakMode;
            self.textContainer.maximumNumberOfLines = self.numberOfLines;
        }

    }
}

func handleTapOnLabel(tapGesture:UITapGestureRecognizer){

    let locationOfTouchInLabel = tapGesture.location(in: tapGesture.view)
    let labelSize = tapGesture.view?.bounds.size
    let textBoundingBox = self.layoutManager.usedRect(for: self.textContainer)
    let textContainerOffset = CGPoint(x: ((labelSize?.width)! - textBoundingBox.size.width) * 0.5 - textBoundingBox.origin.x, y: ((labelSize?.height)! - textBoundingBox.size.height) * 0.5 - textBoundingBox.origin.y)

    let locationOfTouchInTextContainer = CGPoint(x: locationOfTouchInLabel.x - textContainerOffset.x, y: locationOfTouchInLabel.y - textContainerOffset.y)
    let indexOfCharacter = self.layoutManager.characterIndex(for: locationOfTouchInTextContainer, in: self.textContainer, fractionOfDistanceBetweenInsertionPoints: nil)


    self.attributedText?.enumerateAttribute(NSLinkAttributeName, in: NSMakeRange(0, (self.attributedText?.length)!), options: NSAttributedString.EnumerationOptions(rawValue: UInt(0)), using:{
        (attrs: Any?, range: NSRange, stop: UnsafeMutablePointer<ObjCBool>) in

        if NSLocationInRange(indexOfCharacter, range){
            if let _attrs = attrs{

                UIApplication.shared.openURL(URL(string: _attrs as! String)!)
            }
        }
    })

}}

DECLARE @INPUT VARCHAR(5) = '0.12',@INPUT_1 VARCHAR(5)='0.12x';
select CONVERT(float, @INPUT) YOUR_QUERY ,
case when isnumeric(@INPUT_1)=1 THEN CONVERT(float, @INPUT_1) ELSE 0 END AS YOUR_QUERY_ANSWERED

above will return values

however below query wont work

DECLARE @INPUT VARCHAR(5) = '0.12',@INPUT_1 VARCHAR(5)='0.12x';
select CONVERT(float, @INPUT) YOUR_QUERY ,
case when isnumeric(@INPUT_1)=1 THEN CONVERT(float, @INPUT_1) ELSE **@INPUT_1** END AS YOUR_QUERY_ANSWERED

as @INPUT_1 actually has varchar in it.

So your output column must have a varchar in it.

Most answers suggest this is because of different platforms, but there is more to it. From the documentation of object.__hash__(self):

By default, the __hash__() values of str, bytes and datetime objects are “salted” with an unpredictable random value. Although they remain constant within an individual Python process, they are not predictable between repeated invocations of Python.

This is intended to provide protection against a denial-of-service caused by carefully-chosen inputs that exploit the worst case performance of a dict insertion, O(n²) complexity. See http://www.ocert.org/advisories/ocert-2011-003.html for details.

Changing hash values affects the iteration order of dicts, sets and other mappings. Python has never made guarantees about this ordering (and it typically varies between 32-bit and 64-bit builds).

Even running on the same machine will yield varying results across invocations:

$ python -c "print(hash('http://stackoverflow.com'))"
-3455286212422042986
$ python -c "print(hash('http://stackoverflow.com'))"
-6940441840934557333

While:

$ python -c "print(hash((1,2,3)))"
2528502973977326415
$ python -c "print(hash((1,2,3)))"
2528502973977326415

See also the environment variable PYTHONHASHSEED:

If this variable is not set or set to random, a random value is used to seed the hashes of str, bytes and datetime objects.

If PYTHONHASHSEED is set to an integer value, it is used as a fixed seed for generating the hash() of the types covered by the hash randomization.

Its purpose is to allow repeatable hashing, such as for selftests for the interpreter itself, or to allow a cluster of python processes to share hash values.

The integer must be a decimal number in the range [0, 4294967295]. Specifying the value 0 will disable hash randomization.

For example:

$ export PYTHONHASHSEED=0                            
$ python -c "print(hash('http://stackoverflow.com'))"
-5843046192888932305
$ python -c "print(hash('http://stackoverflow.com'))"
-5843046192888932305

I'm sticking to the question as the title states and not the discussion. Which view is top visible on any given point?

@implementation UIView (Extra)

- (UIView *)findTopMostViewForPoint:(CGPoint)point
{
    for(int i = self.subviews.count - 1; i >= 0; i--)
    {
        UIView *subview = [self.subviews objectAtIndex:i];
        if(!subview.hidden && CGRectContainsPoint(subview.frame, point))
        {
            CGPoint pointConverted = [self convertPoint:point toView:subview];
            return [subview findTopMostViewForPoint:pointConverted];
        }
    }

    return self;
}

- (UIWindow *)topmostWindow
{
    UIWindow *topWindow = [[[UIApplication sharedApplication].windows sortedArrayUsingComparator:^NSComparisonResult(UIWindow *win1, UIWindow *win2) {
        return win1.windowLevel - win2.windowLevel;
    }] lastObject];
    return topWindow;
}

@end

Can be used directly with any UIWindow as receiver or any UIView as receiver.

I wasn't completely happy by the --allow-file-access-from-files solution, because I'm using Chrome as my primary browser, and wasn't really happy with this breach I was opening.

Now I'm using Canary ( the chrome beta version ) for my development with the flag on. And the mere Chrome version for my real blogging : the two browser don't share the flag !

To allow you to define variables that you don't want to serialize.

In an object you may have information that you don't want to serialize/persist (perhaps a reference to a parent factory object), or perhaps it doesn't make sense to serialize. Marking these as 'transient' means the serialization mechanism will ignore these fields.

If mipadi's suggestion doesn't work, add this to config/environment.rb

# force Rails into production mode when                          
# you don't control web/app server and can't set it the proper way                  
ENV['RAILS_ENV'] ||= 'production'

I had a similar issue.

The command I used was as follows:

wget -qO https://download.jitsi.org/jitsi-key.gpg.key |  apt-key add -

I forgot a hyphen between the flags and the URL, which is why wget threw an error.

This is the command that finally worked for me:

wget -qO - https://download.jitsi.org/jitsi-key.gpg.key |  apt-key add -

I was using python interpolation and forgot the ending s character:

a = dict(foo='bar')
print("What comes after foo? %(foo)" % a) # Should be %(foo)s

Watch those typos.

You can use the clear method

List<string> test = new List<string>();
test.Clear();

Adding export PATH="$PATH:~/.composer/vendor/bin" to ~/.bashrc works in your case because you only need it when you run the terminal.
For the sake of completeness, appending it to PATH in /etc/environment (sudo gedit /etc/environment and adding ~/.composer/vendor/bin in PATH) will also work even if it is called by other programs because it is system-wide environment variable.

Compress and Send Bitmap

The accepted answer will crash when the Bitmap is too large. I believe it's a 1MB limit. The Bitmap must be compressed into a different file format such as a JPG represented by a ByteArray, then it can be safely passed via an Intent.

Implementation

The function is contained in a separate thread using Kotlin Coroutines because the Bitmap compression is chained after the Bitmap is created from an url String. The Bitmap creation requires a separate thread in order to avoid Application Not Responding (ANR) errors.

Concepts Used

• Kotlin Coroutines notes.
• The Loading, Content, Error (LCE) pattern is used below. If interested you can learn more about it in this talk and video.
• LiveData is used to return the data. I've compiled my favorite LiveData resource in these notes.
• In Step 3, toBitmap() is a Kotlin extension function requiring that library to be added to the app dependencies.

Code

1. Compress Bitmap to JPG ByteArray after it has been created.

Repository.kt

suspend fun bitmapToByteArray(url: String) = withContext(Dispatchers.IO) {
    MutableLiveData<Lce<ContentResult.ContentBitmap>>().apply {
        postValue(Lce.Loading())
        postValue(Lce.Content(ContentResult.ContentBitmap(
            ByteArrayOutputStream().apply {
                try {                     
                    BitmapFactory.decodeStream(URL(url).openConnection().apply {
                        doInput = true
                        connect()
                    }.getInputStream())
                } catch (e: IOException) {
                   postValue(Lce.Error(ContentResult.ContentBitmap(ByteArray(0), "bitmapToByteArray error or null - ${e.localizedMessage}")))
                   null
                }?.compress(CompressFormat.JPEG, BITMAP_COMPRESSION_QUALITY, this)
           }.toByteArray(), "")))
        }
    }

ViewModel.kt

//Calls bitmapToByteArray from the Repository
private fun bitmapToByteArray(url: String) = liveData {
    emitSource(switchMap(repository.bitmapToByteArray(url)) { lce ->
        when (lce) {
            is Lce.Loading -> liveData {}
            is Lce.Content -> liveData {
                emit(Event(ContentResult.ContentBitmap(lce.packet.image, lce.packet.errorMessage)))
            }
            is Lce.Error -> liveData {
                Crashlytics.log(Log.WARN, LOG_TAG,
                        "bitmapToByteArray error or null - ${lce.packet.errorMessage}")
            }
        }
    })
}

2. Pass image as ByteArray via an Intent.

In this sample it's passed from a Fragment to a Service. It's the same concept if being shared between two Activities.

Fragment.kt

ContextCompat.startForegroundService(
    context!!,
    Intent(context, AudioService::class.java).apply {
        action = CONTENT_SELECTED_ACTION
        putExtra(CONTENT_SELECTED_BITMAP_KEY, contentPlayer.image)
    })

3. Convert ByteArray back to Bitmap.

Utils.kt

fun ByteArray.byteArrayToBitmap(context: Context) =
    run {
        BitmapFactory.decodeByteArray(this, BITMAP_OFFSET, size).run {
            if (this != null) this
            // In case the Bitmap loaded was empty or there is an error I have a default Bitmap to return.
            else AppCompatResources.getDrawable(context, ic_coinverse_48dp)?.toBitmap()
        }
    }

Search till the seconds for the timestamp column in postgress

select * from "TableName" e
    where timestamp >= '2020-08-08T13:00:00' and timestamp < '2020-08-08T17:00:00';

I believe you're using \w (word character) where you ought to be using \s (whitespace). Word characters typically consist of [A-Za-z0-9_], so that excludes your space, which then further fails to match on the optional minus sign or a digit.

If you know how PDF files are structured (or are willing to spend a little while reading the spec), you can do it this way.

Use the Named Action "Print" in the OpenAction field of the Catalog object; the "Print" action is undocumented, but Acrobat Reader and most of the other major readers understand it. A nice benefit of this approach is that you don't get any JavaScript warnings. See here for details: http://www.gnostice.com/nl_article.asp?id=157

To make it even shinier, I added a second Action, URI, directing the reader to go back to the page that originated the request. Then I attached this Action to the first Named action using its Next field. With content disposition set to "inline", this makes it so that when the user clicks on the print link:

1. It opens up Adobe Reader in the same tab and loads the file
2. It immediately shows the print dialog
3. As soon as the Print dialog is closed (whether they hit "OK" or "cancel"), the browser tab goes back to the webpage

I was able to do all these changes in Ruby easily enough using only the File and IO modules; I opened the PDF I had generated with an external tool, followed the xref to the existing Catalog section, then appended a new section onto the PDF with an updated Catalog object containing my special OpenAction line, and also the new Action objects.

Because of PDF's incremental revision features, you don't have to make any changes to the existing data to do this, just append an additional section to the end.

Here is an even shorter way of achieving this:

1) using Negative character class pattern matching

irb(main)> "((String1))"[/[^()]+/]
=> "String1"

^ - Matches anything NOT in the character class. Inside the charachter class, we have ( and )

Or with global substitution "AKA: gsub" like others have mentioned.

irb(main)> "((String1))".gsub(/[)(]/, '')
=> "String1"

A little more information on XOR operation.

• XOR a number with itself odd number of times the result is number itself.
• XOR a number even number of times with itself, the result is 0.
• Also XOR with 0 is always the number itself.

Earlier it used to be android:capitalize="words", which is now deprecated. The recommended alternative is to use android:inputType="textCapWords"

Please note that this will only work if your device keyboard Auto Capitalize Setting enabled.

To do this programatically, use the following method:

setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_CAP_WORDS);

Easiest way to do this as shown here, using the standard library class bitset.

To emulate the C# feature in a type-safe way, you'd have to write a template wrapper around the bitset, replacing the int arguments with an enum given as a type parameter to the template. Something like:

    template <class T, int N>
class FlagSet
{

    bitset<N> bits;

    FlagSet(T enumVal)
    {
        bits.set(enumVal);
    }

    // etc.
};

enum MyFlags
{
    FLAG_ONE,
    FLAG_TWO
};

FlagSet<MyFlags, 2> myFlag;

My code below might be a useful implementation, highlighting the main difference between do-while vs while as I understand it.

So in this one case, you always go through the loop at least once.

first_pass = True
while first_pass or condition:
    first_pass = False
    do_stuff()

What is the value range? Is it 0 through 10? If so, then try:

SELECT REPLICATE('0',2-LEN(@t)) + CAST(@t AS VARCHAR)

That handles 0 through 9 as well as 10 through 99.

Now, tinyint can go up to the value of 255. If you want to handle > 99 through 255, then try this solution:

declare @t  TINYINT
set @t =233
SELECT ISNULL(REPLICATE('0',2-LEN(@t)),'') + CAST(@t AS VARCHAR)

To understand the solution, the expression to the left of the + calculates the number of zeros to prefix to the string.

In case of the value 3, the length is 1. 2 - 1 is 1. REPLICATE Adds one zero. In case of the value 10, the length is 2. 2 - 2 is 0. REPLICATE Adds nothing. In the case of the value 100, the length is -1 which produces a NULL. However, the null value is handled and set to an empty string.

Now if you decide that because tinyint can contain up to 255 and you want your formatting as three characters, just change the 2-LEN to 3-LEN in the left expression and you're set.

Try this code

 var vm = new Vue({
     created()
     {
       let urlParams = new URLSearchParams(window.location.search);
           console.log(urlParams.has('yourParam')); // true
           console.log(urlParams.get('yourParam')); // "MyParam"
     },

As Dhruv Gairola answered, you can save the state of the application by using Bundle savedInstanceState. I am trying to give a very simple example that new learners like me can understand easily.

Suppose, you have a simple fragment with a TextView and a Button. Each time you clicked the button the text changes. Now, change the orientation of you device/emulator and notice that you lost the data (means the changed data after clicking you got) and fragment starts as the first time again. By using Bundle savedInstanceState we can get rid of this. If you take a look into the life cyle of the fragment.Fragment Lifecylce you will get that a method "onSaveInstanceState" is called when the fragment is about to destroyed.

So, we can save the state means the changed text value into that bundle like this

 int counter  = 0;
 @Override
 public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("value",counter);
 }

After you make the orientation the "onCreate" method will be called right? so we can just do this

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if(savedInstanceState == null){
        //it is the first time the fragment is being called
        counter = 0;
    }else{
        //not the first time so we will check SavedInstanceState bundle
        counter = savedInstanceState.getInt("value",0); //here zero is the default value
    }
}

Now, you won't lose your value after the orientation. The modified value always will be displayed.

To select and element where you know only the attribute value you can use the below jQuery script

var src = $('.conversation_img[alt="example"]').attr('src');

Please refer the jQuery Documentation for attribute equals selectors

Please also refer to the example in Demo

Following is the code incase you are not able to access the demo..

HTML

<div>
    <img alt="example" src="\images\show.jpg" />
    <img  alt="exampleAll" src="\images\showAll.jpg" />  

</div>

SCRIPT JQUERY

var src = $('img[alt="example"]').attr('src');
alert("source of image with alternate text = example - " + src);


var srcAll = $('img[alt="exampleAll"]').attr('src');
alert("source of image with alternate text = exampleAll - " + srcAll );

Output will be

Two Alert messages each having values

1. source of image with alternate text = example - \images\show.jpg
2. source of image with alternate text = exampleAll - \images\showAll.jpg

With the reference of Biswajit Roy: Dynamic Programming firstly plans then Go. and Greedy algorithm uses greedy choice, it firstly Go then continuously Plans.

If all you want to do is read the same information more than once, and the input data is small enough to fit into memory, you can copy the data from your InputStream to a ByteArrayOutputStream.

Then you can obtain the associated array of bytes and open as many "cloned" ByteArrayInputStreams as you like.

ByteArrayOutputStream baos = new ByteArrayOutputStream();

// Code simulating the copy
// You could alternatively use NIO
// And please, unlike me, do something about the Exceptions :D
byte[] buffer = new byte[1024];
int len;
while ((len = input.read(buffer)) > -1 ) {
    baos.write(buffer, 0, len);
}
baos.flush();
    
// Open new InputStreams using recorded bytes
// Can be repeated as many times as you wish
InputStream is1 = new ByteArrayInputStream(baos.toByteArray()); 
InputStream is2 = new ByteArrayInputStream(baos.toByteArray()); 

But if you really need to keep the original stream open to receive new data, then you will need to track the external call to close(). You will need to prevent close() from being called somehow.

UPDATE (2019):

Since Java 9 the the middle bits can be replaced with InputStream.transferTo:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
input.transferTo(baos);
InputStream firstClone = new ByteArrayInputStream(baos.toByteArray()); 
InputStream secondClone = new ByteArrayInputStream(baos.toByteArray()); 

val df = Seq(
  ("1001", "1007"),
  ("1002", null),
  ("1003", "1005"),
  (null, "1006")
).toDF("user_id", "friend_id")

Data is:

+-------+---------+
|user_id|friend_id|
+-------+---------+
|   1001|     1007|
|   1002|     null|
|   1003|     1005|
|   null|     1006|
+-------+---------+

Drop rows containing any null or NaN values in the specified columns of the Seq:

df.na.drop(Seq("friend_id"))
  .show()

Output:

+-------+---------+
|user_id|friend_id|
+-------+---------+
|   1001|     1007|
|   1003|     1005|
|   null|     1006|
+-------+---------+

If do not specify columns, drop row as long as any column of a row contains null or NaN values:

df.na.drop()
  .show()

Output:

+-------+---------+
|user_id|friend_id|
+-------+---------+
|   1001|     1007|
|   1003|     1005|
+-------+---------+

The most simple way of changing the foreground and background colour of a progress bar is

<ProgressBar
                        style="@android:style/Widget.ProgressBar.Horizontal"
                        android:id="@+id/pb_main"
                        android:layout_width="match_parent"
                        android:layout_height="8dp"
                        android:progress="30"
                        android:progressTint="#82e9de"
                        android:progressBackgroundTint="#82e9de"
                        />

just add

                        android:progressTint="#82e9de" //for foreground colour
                        android:progressBackgroundTint="#82e9de" //for background colour

Simplest solution would be to use tool which allows you to directly specify ranges, like gnu shuf

shuf -i1-10 -n1

If you want to use $RANDOM, it would be more precise to throw out the last 8 numbers in 0...32767, and just treat it as 0...32759, since taking 0...32767 mod 10 you get the following distribution

0-8 each: 3277 
8-9 each: 3276

So, slightly slower but more precise would be

while :; do ran=$RANDOM; ((ran < 32760)) && echo $(((ran%10)+1)) && break; done 

A safe and long way:

1. git branch todelete
2. git checkout todelete
3. git add .
4. git commit -m "I did a bad thing, sorry"
5. git checkout develop
6. git branch -D todelete

I had to run the following on AWS EC2 Linux instance (PHP Version 7.3):

sudo yum install php73-php-pdo php73-php-mysqlnd

// Swift 2

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    let orientation: UIInterfaceOrientationMask =
    [UIInterfaceOrientationMask.Portrait, UIInterfaceOrientationMask.PortraitUpsideDown]
    return orientation
}

I have had a similar question and I was using signal:

import signal

def signal_handler(signal_number, frame):
    print "Proceed ..."

signal.signal(signal.SIGINT, signal_handler)
signal.pause()

So you register a handler for the signal SIGINT and pause waiting for any signal. Now from outside your program (e.g. in bash), you can run kill -2 <python_pid>, which will send signal 2 (i.e. SIGINT) to your python program. Your program will call your registered handler and proceed running.

I agree with the second part of Patrick's answer. Even if in some tests it seems to keep insertion order, the documentation (and normal behavior for dictionaries and hashes) explicitly states the ordering is unspecified.

You're just asking for trouble depending on the ordering of the keys. Add your own bookkeeping (as Patrick said, just a single variable for the last added key) to be sure. Also, don't be tempted by all the methods such as Last and Max on the dictionary as those are probably in relation to the key comparator (I'm not sure about that).

The Problem

Indexes visible in a web browser for directories that do not contain an index.html or index.php file.

I had a lot of trouble with the configuration on Scientific Linux's httpd web server to stop showing these indexes.

The Configuration that did not work

httpd.conf virtual host directory directives:

<Directory /home/mydomain.com/htdocs>
    Options FollowSymLinks
    AllowOverride all
    Require all granted
</Directory>

and the addition of the following line to .htaccess:

Options -Indexes

Directory indexes were still showing up. .htaccess settings weren't working!

How could that be, other settings in .htaccess were working, so why not this one? What's going? It should be working! %#$&^$%@# !!

The Fix

Change httpd.conf's Options line to:

Options +FollowSymLinks

and restart the webserver.

From Apache's core mod page: ( https://httpd.apache.org/docs/2.4/mod/core.html#options )

Mixing Options with a + or - with those without is not valid syntax and will be rejected during server startup by the syntax check with an abort.

Voilà directory indexes were no longer showing up for directories that did not contain an index.html or index.php file.

Now What! A New Wrinkle

New entries started to show up in the 'error_log' when such a directory access was attempted:

[Fri Aug 19 02:57:39.922872 2016] [autoindex:error] [pid 12479] [client aaa.bbb.ccc.ddd:xxxxx] AH01276: Cannot serve directory /home/mydomain.com/htdocs/dir-without-index-file/: No matching DirectoryIndex (index.html,index.php) found, and server-generated directory index forbidden by Options directive

This entry is from the Apache module 'autoindex' with a LogLevel of 'error' as indicated by [autoindex:error] of the error message---the format is [module_name:loglevel].

To stop these new entries from being logged, the LogLevel needs to be changed to a higher level (e.g. 'crit') to log fewer---only more serious error messages.

Apache 2.4 LogLevels

See Apache 2.4's core directives for LogLevel.

emerg, alert, crit, error, warn, notice, info, debug, trace1, trace2, trace3, tracr4, trace5, trace6, trace7, trace8

Each level deeper into the list logs all the messages of any previous level(s).

Apache 2.4's default level is 'warn'. Therefore, all messages classified as emerg, alert, crit, error, and warn are written to error_log.

Additional Fix to Stop New error_log Entries

Added the following line inside the <Directory>..</Directory> section of httpd.conf:

LogLevel crit

The Solution 1

My virtual host's httpd.conf <Directory>..</Directory> configuration:

<Directory /home/mydomain.com/htdocs>
    Options +FollowSymLinks
    AllowOverride all
    Require all granted
    LogLevel crit
</Directory>

and adding to /home/mydomain.com/htdocs/.htaccess, the root directory of your website's .htaccess file:

Options -Indexes

If you don't mind the 'error' level messages, omit

LogLevel crit

Scientific Linux - Solution 2 - Disables mod_autoindex

No more autoindex'ing of directories inside your web space. No changes to .htaccess. But, need access to the httpd configuration files in /etc/httpd

1. Edit /etc/httpd/conf.modules.d/00-base.conf and comment the line:

   LoadModule autoindex_module modules/mod_autoindex.so
   

   by adding a # in front of it then save the file.

2. In the directory /etc/httpd/conf.d rename (mv)

   sudo mv autoindex.conf autoindex.conf.<something_else>
   

3. Restart httpd:

   sudo httpd -k restart
   

   or

   sudo apachectl restart
   

The autoindex_mod is now disabled.

Linux distros with ap2dismod/ap2enmod Commands

Disable autoindex module enter the command

    sudo a2dismod autoindex

to enable autoindex module enter

    sudo a2enmod autoindex

I tried this it works

open

vendor\guzzlehttp\guzzle\src\Handler\CurlFactory.php

and change this

 $conf[CURLOPT_SSL_VERIFYHOST] = 2;
 `enter code here`$conf[CURLOPT_SSL_VERIFYPEER] = true;

to this

$conf[CURLOPT_SSL_VERIFYHOST] = 0;
$conf[CURLOPT_SSL_VERIFYPEER] = FALSE;

I think you could just use the String#length method...

http://ruby-doc.org/core-1.9.3/String.html#method-i-length

Example:

text = 'The quick brown fox jumps over the lazy dog.'
puts text.length > 25 ? 'Too many characters' : 'Accepted'

open() will be called at the end of each of the fopen() family functions. open() is a system call and fopen() are provided by libraries as a wrapper functions for user easy of use

There not a method with the name 'ConvertToPlainText' in the HtmlAgilityPack but you can convert a html string to CLEAR string with :

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(htmlString);
var textString = doc.DocumentNode.InnerText;
Regex.Replace(textString , @"<(.|n)*?>", string.Empty).Replace("&nbsp", "");

Thats works for me. BUT I DONT FIND A METHOD WITH NAME 'ConvertToPlainText' IN 'HtmlAgilityPack'.

I have experienced the same situation I did the below as this much easier. By passing commit-Id you can reach to the particular commit you want to go:

git reset --hard {commit-id}

As you want to remove your last commit so you need to pass the commit-Id where you need to move your pointer:

git reset --hard db0c078d5286b837532ff5e276dcf91885df2296

If you dont need a feedback about the requested data and also dont need any interactivity between the opener and the popup, you can post a hidden form into the popup:

Example:

<form method="post" target="popup" id="formID" style="display:none" action="https://example.com/barcode/generate" >
  <input type="hidden" name="packing_slip" value="35592" />
  <input type="hidden" name="reference" value="0018439" />
  <input type="hidden" name="total_boxes" value="1" />
</form>
<script type="text/javascript">
window.open('about:blank','popup','width=300,height=200')
document.getElementById('formID').submit();
</script>

Otherwise you could use jsonp. But this works only, if you have access to the other Server, because you have to modify the response.

To clarify one point in @EdChum's answer, per the documentation, you can include the object columns by using df.describe(include='all'). It won't provide many statistics, but will provide a few pieces of info, including count, number of unique values, top value. This may be a new feature, I don't know as I am a relatively new user.

Hack grep's color function, and count how many color tags it prints out:

echo -e "a\nb  b b\nc\ndef\nb e brb\nr" \
| GREP_COLOR="033" grep --color=always  b \
| perl -e 'undef $/; $_=<>; s/\n//g; s/\x1b\x5b\x30\x33\x33/\n/g; print $_' \
| wc -l

Ideally, there should only be two scenarios of when an iOS application would need to accept an un-trusted certificate.

Scenario A: You are connected to a test environment which is using a self-signed certificate.

Scenario B: You are Proxying HTTPS traffic using a MITM Proxy like Burp Suite, Fiddler, OWASP ZAP, etc. The Proxies will return a certificate signed by a self-signed CA so that the proxy is able to capture HTTPS traffic.

Production hosts should never use un-trusted certificates for obvious reasons.

If you need to have the iOS simulator accept an un-trusted certificate for testing purposes it is highly recommended that you do not change application logic in order disable the built in certificate validation provided by the NSURLConnection APIs. If the application is released to the public without removing this logic, it will be susceptible to man-in-the-middle attacks.

The recommended way to accept un-trusted certificates for testing purposes is to import the Certificate Authority(CA) certificate which signed the certificate onto your iOS Simulator or iOS device. I wrote up a quick blog post which demonstrates how to do this which an iOS Simulator at:

accepting untrusted certificates using the ios simulator

I too faced this issue. I've tried the solutions mentioned here. The issue seems not with the source folder.

For me the issue occurred when I installed a new version of IntelliJ, was using 2019 version moved to 2020 version. The project got opened in the new version but the declarations were missing.

I fixed this by :

 - File>Project Structure.  
 - Under Project Settings go to Modules. Here you should see the different project folders, for me it was not there. 
 - Click the + button on top and click Import Module.
 - Select the root pom.xml and wait for the indexing to complete.

After the indexing is done all the declarations were working.

You can store the output of another query in a variable and latter you can use the same in your code:

set var=select count(*) from My_table;
${hiveconf:var};

If you don't have DBA rights then you can use user_segments table:

select bytes/1024/1024 MB from user_segments where segment_name='Table_name'

app.component.ts

behaviourService.setName("behaviour");

behaviour.service.ts

private name = new BehaviorSubject("");
getName = this.name.asObservable();`

constructor() {}

setName(data) {
    this.name.next(data);
}

custom.component.ts

behaviourService.subscribe(response=>{
    console.log(response);    //output: behaviour
});

You can use one of the following technique to remove the last comma(,)

Solution1:

$string = "'name', 'name2', 'name3',";  // this is the full string or text.
$string = chop($string,",");            // remove the last character (,) and store the updated value in $string variable.
echo $string;                           // to print update string.

Solution 2:

$string = '10,20,30,';              // this is the full string or text.
$string = rtrim($string,',');
echo $string;                       // to print update string.

Solution 3:

 $string = "'name', 'name2', 'name3',";  // this is the full string or text.
 $string = substr($string , 0, -1);
 echo $string;  

Using the gedit text editor (3.18.3)

1. Click Search
2. Click Find and Replace...
3. Enter \n\s into Find field
4. Leave Replace with blank (nothing)
5. Check Regular expression box
6. Click the Find button

Note: this doesn't exactly address the OP's original, 7 year old problem but should help some noob linux users (like me) who find their way here from the SE's with similar "how do I get my text all on one line" questions.

you can use "__range" for example :

from datetime import datetime
start_date=datetime(2009, 12, 30)
end_end=datetime(2020,12,30)
Sample.objects.filter(date__range=[start_date,end_date])

Slightly more than just displaying the function, how about getting the edit in-place facility as well.

\ef <function_name> is very handy. It will open the source code of the function in editable format. You will not only be able to view it, you can edit and execute it as well.

Just \ef without function_name will open editable CREATE FUNCTION template.

For further reference -> https://www.postgresql.org/docs/9.6/static/app-psql.html

$ PATH=$PATH:/Library/PostgreSQL/9.1/bin sudo gem install pg

replace the 9.1 for the version installed on your system.

This might work for you (GNU sed):

sed 'y/:/\n/' file

or perhaps:

sed y/:/$"\n"/ file

For ViewPager2,

viewPager.registerOnPageChangeCallback(object : ViewPager2.OnPageChangeCallback() {
  override fun onPageSelected(position: Int) {
    super.onPageSelected(position)
  }
})

where OnPageChangeCallback is a static class with three methods:

onPageScrolled(int position, float positionOffset, @Px int positionOffsetPixels),
onPageSelected(int position), 
onPageScrollStateChanged(@ScrollState int state)

Simulating a mouse click

My guess is that the webpage is listening to mousedown rather than click (which is bad for accessibility because when a user uses the keyboard, only focus and click are fired, not mousedown). So you should simulate mousedown, click, and mouseup (which, by the way, is what the iPhone, iPod Touch, and iPad do on tap events).

To simulate the mouse events, you can use this snippet for browsers that support DOM 2 Events. For a more foolproof simulation, fill in the mouse position using initMouseEvent instead.

// DOM 2 Events
var dispatchMouseEvent = function(target, var_args) {
  var e = document.createEvent("MouseEvents");
  // If you need clientX, clientY, etc., you can call
  // initMouseEvent instead of initEvent
  e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
dispatchMouseEvent(element, 'mouseover', true, true);
dispatchMouseEvent(element, 'mousedown', true, true);
dispatchMouseEvent(element, 'click', true, true);
dispatchMouseEvent(element, 'mouseup', true, true);

When you fire a simulated click event, the browser will actually fire the default action (e.g. navigate to the link's href, or submit a form).

In IE, the equivalent snippet is this (unverified since I don't have IE). I don't think you can give the event handler mouse positions.

// IE 5.5+
element.fireEvent("onmouseover");
element.fireEvent("onmousedown");
element.fireEvent("onclick");  // or element.click()
element.fireEvent("onmouseup");

Simulating keydown and keypress

You can simulate keydown and keypress events, but unfortunately in Chrome they only fire the event handlers and don't perform any of the default actions. I think this is because the DOM 3 Events working draft describes this funky order of key events:

1. keydown (often has default action such as fire click, submit, or textInput events)
2. keypress (if the key isn't just a modifier key like Shift or Ctrl)
3. (keydown, keypress) with repeat=true if the user holds down the button
4. default actions of keydown!!
5. keyup

This means that you have to (while combing the HTML5 and DOM 3 Events drafts) simulate a large amount of what the browser would otherwise do. I hate it when I have to do that. For example, this is roughly how to simulate a key press on an input or textarea.

// DOM 3 Events
var dispatchKeyboardEvent = function(target, initKeyboradEvent_args) {
  var e = document.createEvent("KeyboardEvents");
  e.initKeyboardEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
var dispatchTextEvent = function(target, initTextEvent_args) {
  var e = document.createEvent("TextEvent");
  e.initTextEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};
var dispatchSimpleEvent = function(target, type, canBubble, cancelable) {
  var e = document.createEvent("Event");
  e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
  target.dispatchEvent(e);
};

var canceled = !dispatchKeyboardEvent(element,
    'keydown', true, true,  // type, bubbles, cancelable
    null,  // window
    'h',  // key
    0, // location: 0=standard, 1=left, 2=right, 3=numpad, 4=mobile, 5=joystick
    '');  // space-sparated Shift, Control, Alt, etc.
dispatchKeyboardEvent(
    element, 'keypress', true, true, null, 'h', 0, '');
if (!canceled) {
  if (dispatchTextEvent(element, 'textInput', true, true, null, 'h', 0)) {
    element.value += 'h';
    dispatchSimpleEvent(element, 'input', false, false);
    // not supported in Chrome yet
    // if (element.form) element.form.dispatchFormInput();
    dispatchSimpleEvent(element, 'change', false, false);
    // not supported in Chrome yet
    // if (element.form) element.form.dispatchFormChange();
  }
}
dispatchKeyboardEvent(
    element, 'keyup', true, true, null, 'h', 0, '');

I don't think it is possible to simulate key events in IE.

Check out javax.imageio, especially ImageReader and ImageWriter as an abstraction for reading and writing image files.

BufferedImage.getRGB(int x, int y) than allows you to get RGB values on the given pixel, which can be chunked into bytes.

Note: I think you don't want to read the raw bytes, because then you have to deal with all the compression/decompression.

This is the functional programming method. It lifts the tuple expansion feature out of syntax sugar:

apply_tuple = lambda f, t: f(*t)

Redefine apply_tuple via curry to save a lot of partial calls in the long run:

from toolz import curry
apply_tuple = curry(apply_tuple)

Example usage:

from operator import add, eq
from toolz import thread_last

thread_last(
    [(1,2), (3,4)],
    (map, apply_tuple(add)),
    list,
    (eq, [3, 7])
)
# Prints 'True'

You could replace the original jQuery addClass and removeClass functions with your own that would call the original functions and then trigger a custom event. (Using a self-invoking anonymous function to contain the original function reference)

(function( func ) {
    $.fn.addClass = function() { // replace the existing function on $.fn
        func.apply( this, arguments ); // invoke the original function
        this.trigger('classChanged'); // trigger the custom event
        return this; // retain jQuery chainability
    }
})($.fn.addClass); // pass the original function as an argument

(function( func ) {
    $.fn.removeClass = function() {
        func.apply( this, arguments );
        this.trigger('classChanged');
        return this;
    }
})($.fn.removeClass);

Then the rest of your code would be as simple as you'd expect.

$(selector).on('classChanged', function(){ /*...*/ });

Update:

This approach does make the assumption that the classes will only be changed via the jQuery addClass and removeClass methods. If classes are modified in other ways (such as direct manipulation of the class attribute through the DOM element) use of something like MutationObservers as explained in the accepted answer here would be necessary.

Also as a couple improvements to these methods:

• Trigger an event for each class being added (classAdded) or removed (classRemoved) with the specific class passed as an argument to the callback function and only triggered if the particular class was actually added (not present previously) or removed (was present previously)

• Only trigger classChanged if any classes are actually changed

  (function( func ) {
      $.fn.addClass = function(n) { // replace the existing function on $.fn
          this.each(function(i) { // for each element in the collection
              var $this = $(this); // 'this' is DOM element in this context
              var prevClasses = this.getAttribute('class'); // note its original classes
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString(); // retain function-type argument support
              $.each(classNames.split(/\s+/), function(index, className) { // allow for multiple classes being added
                  if( !$this.hasClass(className) ) { // only when the class is not already present
                      func.call( $this, className ); // invoke the original function to add the class
                      $this.trigger('classAdded', className); // trigger a classAdded event
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged'); // trigger the classChanged event
          });
          return this; // retain jQuery chainability
      }
  })($.fn.addClass); // pass the original function as an argument
  
  (function( func ) {
      $.fn.removeClass = function(n) {
          this.each(function(i) {
              var $this = $(this);
              var prevClasses = this.getAttribute('class');
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString();
              $.each(classNames.split(/\s+/), function(index, className) {
                  if( $this.hasClass(className) ) {
                      func.call( $this, className );
                      $this.trigger('classRemoved', className);
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged');
          });
          return this;
      }
  })($.fn.removeClass);
  

With these replacement functions you can then handle any class changed via classChanged or specific classes being added or removed by checking the argument to the callback function:

$(document).on('classAdded', '#myElement', function(event, className) {
    if(className == "something") { /* do something */ }
});

Docker hub plans have restrictions on number of private repositories that a namespace can use. For instance, the free plan will only allow you to use one private repository at any point in time for an account.

If you are under your plan limits, then your push will succeed. Otherwise, an empty repository with an appropriate tag will be created but the image itself wont be pushed.

In my case, I created the repositories as public using the web console prior to pushing the images.

There is no space allocated for the strings. use array (or) pointers with malloc() and free()

Other than that

#import <stdio.h>
#import <string.h>

should be

#include <stdio.h>
#include <string.h>

NOTE:

• anything that is malloc()ed must be free()'ed
• you need to allocate n + 1 bytes for a string which is of length n (the last byte is for \0)

Please you the following code as a reference

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char *argv[])
{
    //char *str1 = "First string";
    char *str1 = "First string is a big string";
    char *str2 = NULL;

    if ((str2 = (char *) malloc(sizeof(char) * strlen(str1) + 1)) == NULL) {
        printf("unable to allocate memory \n");
        return -1; 
    }   

    strcpy(str2, str1);

    printf("str1 : %s \n", str1);
    printf("str2 : %s \n", str2);

    free(str2);
    return 0;
}

run init after AdamOptimizer,and without define init before or run init

How about:

if (regexMatcher.find()) {
    resultString = regexMatcher.replaceAll(
            String.valueOf(3 * Integer.parseInt(regexMatcher.group(1))));
}

To get the first match, use #find(). After that, you can use #group(1) to refer to this first match, and replace all matches by the first maches value multiplied by 3.

And in case you want to replace each match with that match's value multiplied by 3:

    Pattern p = Pattern.compile("(\\d{1,2})");
    Matcher m = p.matcher("12 54 1 65");
    StringBuffer s = new StringBuffer();
    while (m.find())
        m.appendReplacement(s, String.valueOf(3 * Integer.parseInt(m.group(1))));
    System.out.println(s.toString());

You may want to look through Matcher's documentation, where this and a lot more stuff is covered in detail.

Suppose you want to display some live feed content (say livefeed.txt) on you web page without any page refresh then the following simplified example is for you.

In the below html file, the live data gets updated on the div element of id "liveData"

index.html

<!DOCTYPE html>
<html>
<head>
    <title>Live Update</title>
    <meta charset="UTF-8">
    <script type="text/javascript" src="autoUpdate.js"></script>
</head>
<div id="liveData">
    <p>Loading Data...</p>
</div>
</body>
</html>

Below autoUpdate.js reads the live data using XMLHttpRequest object and updates the html div element on every 1 second. I have given comments on most part of the code for better understanding.

autoUpdate.js

window.addEventListener('load', function()
{
    var xhr = null;

    getXmlHttpRequestObject = function()
    {
        if(!xhr)
        {               
            // Create a new XMLHttpRequest object 
            xhr = new XMLHttpRequest();
        }
        return xhr;
    };

    updateLiveData = function()
    {
        var now = new Date();
        // Date string is appended as a query with live data 
        // for not to use the cached version 
        var url = 'livefeed.txt?' + now.getTime();
        xhr = getXmlHttpRequestObject();
        xhr.onreadystatechange = evenHandler;
        // asynchronous requests
        xhr.open("GET", url, true);
        // Send the request over the network
        xhr.send(null);
    };

    updateLiveData();

    function evenHandler()
    {
        // Check response is ready or not
        if(xhr.readyState == 4 && xhr.status == 200)
        {
            dataDiv = document.getElementById('liveData');
            // Set current data text
            dataDiv.innerHTML = xhr.responseText;
            // Update the live data every 1 sec
            setTimeout(updateLiveData(), 1000);
        }
    }
});

For testing purpose: Just write some thing in the livefeed.txt - You will get updated the same in index.html without any refresh.

livefeed.txt

Hello
World
blah..
blah..

Note: You need to run the above code on the web server (ex: http://localhost:1234/index.html) not as a client html file (ex: file:///C:/index.html).

What I tend to do, and I believe this is what Google intended for developers to do too, is to still get the extras from an Intent in an Activity and then pass any extra data to fragments by instantiating them with arguments.

There's actually an example on the Android dev blog that illustrates this concept, and you'll see this in several of the API demos too. Although this specific example is given for API 3.0+ fragments, the same flow applies when using FragmentActivity and Fragment from the support library.

You first retrieve the intent extras as usual in your activity and pass them on as arguments to the fragment:

public static class DetailsActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // (omitted some other stuff)

        if (savedInstanceState == null) {
            // During initial setup, plug in the details fragment.
            DetailsFragment details = new DetailsFragment();
            details.setArguments(getIntent().getExtras());
            getSupportFragmentManager().beginTransaction().add(
                    android.R.id.content, details).commit();
        }
    }
}

In stead of directly invoking the constructor, it's probably easier to use a static method that plugs the arguments into the fragment for you. Such a method is often called newInstance in the examples given by Google. There actually is a newInstance method in DetailsFragment, so I'm unsure why it isn't used in the snippet above...

Anyways, all extras provided as argument upon creating the fragment, will be available by calling getArguments(). Since this returns a Bundle, its usage is similar to that of the extras in an Activity.

public static class DetailsFragment extends Fragment {
    /**
     * Create a new instance of DetailsFragment, initialized to
     * show the text at 'index'.
     */
    public static DetailsFragment newInstance(int index) {
        DetailsFragment f = new DetailsFragment();

        // Supply index input as an argument.
        Bundle args = new Bundle();
        args.putInt("index", index);
        f.setArguments(args);

        return f;
    }

    public int getShownIndex() {
        return getArguments().getInt("index", 0);
    }

    // (other stuff omitted)

}

Toolbear74 is right log4j.XML is required. In order to get the XML to validate the <param> tags need to be BEFORE the <rollingPolicy> I suggest setting a logging threshold <param name="threshold" value="info"/>

When Creating a Log4j.xml file don't forget to to copy the log4j.dtd into the same location.

Here is an example:

<?xml version="1.0" encoding="windows-1252"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd" >
<log4j:configuration>
<!-- Daily Rolling File Appender that compresses old files -->
  <appender name="file" class="org.apache.log4j.rolling.RollingFileAppender" >
     <param name="threshold" value="info"/>
     <rollingPolicy name="file"  
                      class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
        <param name="FileNamePattern" 
               value="${catalina.base}/logs/myapp.log.%d{yyyy-MM-dd}.gz"/>
        <param name="ActiveFileName" value="${catalina.base}/logs/myapp.log"/>
     </rollingPolicy>
     <layout class="org.apache.log4j.EnhancedPatternLayout" >
        <param name="ConversionPattern" 
               value="%d{ISO8601} %-5p - %-26.26c{1} - %m%n" />
    </layout>
  </appender>

  <root>
    <priority value="debug"></priority>
    <appender-ref ref="file" />
  </root>
</log4j:configuration>

Considering that your setting a FileNamePattern and an ActiveFileName I think that setting a File property is redundant and possibly even erroneous

Try renaming your log4j.properties and dropping in a log4j.xml similar to my example and see what happens.

As this is the first result on google and there's no C++20 answer yet, here's how to use std::chrono to do this:

#include <chrono>

//...

using namespace std::chrono;
int64_t timestamp = duration_cast<milliseconds>(system_clock::now().time_since_epoch()).count();

In versions of C++ before 20, system_clock's epoch being Unix epoch is a de-facto convention, but it's not standardized. If you're not on C++20, use at your own risk.

You can create GitHub repositories via the command line using their Repositories API (http://develop.github.com/p/repo.html)

Check Creating github repositories with command line | Do it yourself Android for example usage.

It's very easy:

numb = raw_input('Input Line: ')
fiIn = open('file.txt').readlines()
for lines in fiIn:
   if numb == lines[0]:
      print lines

Nobody mentioned this, but in some cases the other method fails to recognize the datetime...

You can try this instead, which will convert the specified string representation of a date and time to an equivalent date and time value

string iDate = "05/05/2005";
DateTime oDate = Convert.ToDateTime(iDate);
MessageBox.Show(oDate.Day + " " + oDate.Month + "  " + oDate.Year );

You can either set with ngModel either with [checked] attribute. ngModel binded property should be set to 'true':

1.

  <mat-checkbox class = "example-margin" [(ngModel)] = "myModel"> 
    <label>Printer </label> 
  </mat-checkbox>

2.

<mat-checkbox [checked]= "myModel" class = "example-margin" > 
    <label>Printer </label> 
</mat-checkbox>

3.

<mat-checkbox [ngModel]="myModel" class="example-margin">
    <label>Printer </label> 
</mat-checkbox>

For my layout, I didn't want a hack (no width increasing, no on click with auto and then coming to original). It broke my existing layout. I just wanted it to work normally like other browsers.

I found this to be exactly like that :-

http://www.jquerybyexample.net/2012/05/fix-for-ie-select-dropdown-with-fixed.html

dict.update() looks like it will do what you want...

>> orig.update(extra)
>>> orig
{'A': 1, 'C': 3, 'B': 2, 'E': 5, 'D': 4}
>>> 

Perhaps, though, you don't want to update your original dictionary, but work on a copy:

>>> dest = orig.copy()
>>> dest.update(extra)
>>> orig
{'A': 1, 'C': 3, 'B': 2}
>>> dest
{'A': 1, 'C': 3, 'B': 2, 'E': 5, 'D': 4}

Your requirements are all over the place, but this is the solution to my understanding of them:

To group by Reference property:

var refGroupQuery = (from m in context.Measurements
            group m by m.Reference into refGroup
            select refGroup);

Now you say you want to limit results by "most recent numOfEntries" - I take this to mean you want to limit the returned Measurements... in that case:

var limitedQuery = from g in refGroupQuery
                   select new
                   {
                       Reference = g.Key,
                       RecentMeasurements = g.OrderByDescending( p => p.CreationTime ).Take( numOfEntries )
                   }

To order groups by first Measurement creation time (note you should order the measurements; if you want the earliest CreationTime value, substitue "g.SomeProperty" with "g.CreationTime"):

var refGroupsOrderedByFirstCreationTimeQuery = limitedQuery.OrderBy( lq => lq.RecentMeasurements.OrderBy( g => g.SomeProperty ).First().CreationTime );

To order groups by average CreationTime, use the Ticks property of the DateTime struct:

var refGroupsOrderedByAvgCreationTimeQuery = limitedQuery.OrderBy( lq => lq.RecentMeasurements.Average( g => g.CreationTime.Ticks ) );

I needed to read a huge ResultSet and update some records in the table. I tried to use chunks as suggested in Drew Noakes's answer.

Unfortunately after 50000 records I've got OutofMemoryException. The answer Entity framework large data set, out of memory exception explains, that

EF creates second copy of data which uses for change detection (so that it can persist changes to the database). EF holds this second set for the lifetime of the context and its this set thats running you out of memory.

The recommendation is to re-create your context for each batch.

So I've retrieved Minimal and Maximum values of the primary key- the tables have primary keys as auto incremental integers.Then I retrieved from the database chunks of records by opening context for each chunk. After processing the chunk context closes and releases the memory. It insures that memory usage is not growing.

Below is a snippet from my code:

  public void ProcessContextByChunks ()
  {
        var tableName = "MyTable";
         var startTime = DateTime.Now;
        int i = 0;
         var minMaxIds = GetMinMaxIds();
        for (int fromKeyID= minMaxIds.From; fromKeyID <= minMaxIds.To; fromKeyID = fromKeyID+_chunkSize)
        {
            try
            {
                using (var context = InitContext())
                {   
                    var chunk = GetMyTableQuery(context).Where(r => (r.KeyID >= fromKeyID) && (r.KeyID < fromKeyID+ _chunkSize));
                    try
                    {
                        foreach (var row in chunk)
                        {
                            foundCount = UpdateRowIfNeeded(++i, row);
                        }
                        context.SaveChanges();
                    }
                    catch (Exception exc)
                    {
                        LogChunkException(i, exc);
                    }
                }
            }
            catch (Exception exc)
            {
                LogChunkException(i, exc);
            }
        }
        LogSummaryLine(tableName, i, foundCount, startTime);
    }

    private FromToRange<int> GetminMaxIds()
    {
        var minMaxIds = new FromToRange<int>();
        using (var context = InitContext())
        {
            var allRows = GetMyTableQuery(context);
            minMaxIds.From = allRows.Min(n => (int?)n.KeyID ?? 0);  
            minMaxIds.To = allRows.Max(n => (int?)n.KeyID ?? 0);
        }
        return minMaxIds;
    }

    private IQueryable<MyTable> GetMyTableQuery(MyEFContext context)
    {
        return context.MyTable;
    }

    private  MyEFContext InitContext()
    {
        var context = new MyEFContext();
        context.Database.Connection.ConnectionString = _connectionString;
        //context.Database.Log = SqlLog;
        return context;
    }

FromToRange is a simple structure with From and To properties.

There really isn't a single "answer" to this question, but there are definitely some helpful concepts that can help you to come to a decision.

The first question that needs to be answered in your use case is "Do I want to use the system Python?" If you want to use the Python distributed with your operating system, then using the apt-get install method may be just fine. Depending on the operating system distribution method though, you still have to ask some more questions, such as "Do I want to install multiple versions of this package?" If the answer is yes, then it is probably not a good idea to use something like apt. Dpkg pretty much will just untar an archive at the root of the filesystem, so it is up to the package maintainer to make sure the package installs safely under very little assumptions. In the case of most debian packages, I would assume (someone can feel free to correct me here) that they simply untar and provide a top level package.

For example, say the package is "virtualenv", you'd end up with /usr/lib/python2.x/site-packages/virtualenv. If you install it with easy_install you'd get something like /usr/lib/python2.x/site-packages/virtualenv.egg-link that might point to /usr/lib/python2.x/site-packages/virtualenv-1.2-2.x.egg which may be a directory or zipped egg. Pip does something similar although it doesn't use eggs and instead will place the top level package directly in the lib directory.

I might be off on the paths, but the point is that each method takes into account different needs. This is why tools like virtualenv are helpful as they allow you to sandbox your Python libraries such that you can have any combination you need of libraries and versions.

Setuptools also allows installing packages as multiversion which means there is not a singular module_name.egg-link created. To import those packages you need to use pkg_resources and the __import__ function.

Going back to your original question, if you are happy with the system python and plan on using virtualenv and pip to build environments for different applications, then installing virtualenv and / or pip at the system level using apt-get seems totally appropriate. One word of caution though is that if you plan on upgrading your distributions Python, that may have a ripple effect through your virtualenvs if you linked back to your system site packages.

I should also mention that none of these options is inherently better than the others. They simply take different approaches. Using the system version is an excellent way to install Python applications, yet it can be a very difficult way to develop with Python. Easy install and setuptools is very convenient in a world without virtualenv, but if you need to use different versions of the same library, then it also become rather unwieldy. Pip and virtualenv really act more like a virtual machine. Instead of taking care to install things side by side, you just create an whole new environment. The downside here is that 30+ virtualenvs later you might have used up quite bit of diskspace and cluttered up your filesystem.

As you can see, with the many options it is difficult to say which method to use, but with a little investigation into your use cases, you should be able to find a method that works.

A pop-up is a child of the parent window, but it is not a child of the parent DOCUMENT. It is its own independent browser window and is not contained by the parent.

Use an absolutely-positioned DIV and a translucent overlay instead.

EDIT - example

You need jQuery for this:

<style>
html, body {
    height:100%
}


#overlay { 
    position:absolute;
    z-index:10;
    width:100%;
    height:100%;
    top:0;
    left:0;
    background-color:#f00;
    filter:alpha(opacity=10);
    -moz-opacity:0.1;
    opacity:0.1;
    cursor:pointer;

} 

.dialog {
    position:absolute;
    border:2px solid #3366CC;
    width:250px;
    height:120px;
    background-color:#ffffff;
    z-index:12;
}

</style>
<script type="text/javascript">
$(document).ready(function() { init() })

function init() {
    $('#overlay').click(function() { closeDialog(); })
}

function openDialog(element) {
    //this is the general dialog handler.
    //pass the element name and this will copy
    //the contents of the element to the dialog box

    $('#overlay').css('height', $(document.body).height() + 'px')
    $('#overlay').show()
    $('#dialog').html($(element).html())
    centerMe('#dialog')
    $('#dialog').show();
}

function closeDialog() {
    $('#overlay').hide();
    $('#dialog').hide().html('');
}

function centerMe(element) {
    //pass element name to be centered on screen
    var pWidth = $(window).width();
    var pTop = $(window).scrollTop()
    var eWidth = $(element).width()
    var height = $(element).height()
    $(element).css('top', '130px')
    //$(element).css('top',pTop+100+'px')
    $(element).css('left', parseInt((pWidth / 2) - (eWidth / 2)) + 'px')
}


</script>


<a href="javascript:;//close me" onclick="openDialog($('#content'))">show dialog A</a>

I have managed to get my PDA working properly with Windows 10.

For transparency when I posted the original question I had upgraded a Windows 8.1 PC to Windows 10, I have since moved to using a different PC that had a clean Windows 10 installation.

These are the steps I followed to solve the problem:

• First of all I installed Visual Studio 2008.
• Then I installed Microsoft Windows Mobile Device Center 6.1
  • http://www.microsoft.com/en-us/download/details.aspx?id=3182
• Then Windows Mobile 6 Professional and Standard Software Development Kits Refresh
  • http://www.microsoft.com/en-us/download/details.aspx?id=6135
• Then Windows Mobile 6.5 Developer Tool Kit
  • http://www.microsoft.com/en-us/download/details.aspx?id=17284
• Finally I opened up the Mobile Device Center, went to Mobile Device Settings -> Connection Settings and made sure DMA was selected under "Allow connections to one of the following"

Deleting client ID and creating new one a couple of times worked for me.

Using TempData

Represents a set of data that persists only from one request to the next

[HttpPost]
public ActionResult FillStudent(Student student1)
{
    TempData["student"]= new Student();
    return RedirectToAction("GetStudent","Student");
}

[HttpGet]
public ActionResult GetStudent(Student passedStd)
{
    Student std=(Student)TempData["student"];
    return View();
}

Alternative way Pass the data using Query string

return RedirectToAction("GetStudent","Student", new {Name="John", Class="clsz"});

This will generate a GET Request like Student/GetStudent?Name=John & Class=clsz

Ensure the method you want to redirect to is decorated with [HttpGet] as the above RedirectToAction will issue GET Request with http status code 302 Found (common way of performing url redirect)

As Pax rightly said, measure, don't guess. That what I did for DNSwitness and the results were suprising: the ideal number of threads was much higher than I thought, something like 15,000 threads to get the fastest results.

Of course, it depends on many things, that's why you must measure yourself.

Complete measures (in French only) in Combien de fils d'exécution ?.

Check this: http://jsfiddle.net/h7kRt/1/,

you should change in jsfiddle on top-left to No-wrap in <head>

Your code looks good and it will work inside a normal page. In jsfiddle your function was being defined inside a load handler and thus is in a different scope. By changing to No-wrap you have it in the global scope and can use it as you wanted.

One way I like to use is Vanilla JavaScript with template literal:

var templateLiteral = [`
    <!-- HTML_CODE_COMES_HERE -->
`]

var head = document.querySelector("head");
head.innerHTML = templateLiteral;

The main use of -f is to force the removal of files that would not be removed using rm by itself (as a special case, it "removes" non-existent files, thus suppressing the error message).

You can also just redirect the error message using

$ rm file.txt 2> /dev/null

(or your operating system's equivalent). You can check the value of $? immediately after calling rm to see if a file was actually removed or not.

Here is a better version with better output formatting and C++ 11 features:

void subset_sum_rec(std::vector<int> & nums, const int & target, std::vector<int> & partialNums) 
{

Using linq:

prods.Remove( prods.Single( s => s.ID == 1 ) );

Maybe you even want to use SingleOrDefault() and check if the element exists at all ...

EDIT:
Since stuff is a struct, SingleOrDefault() will not return null. But it will return default( stuff ), which will have an ID of 0. When you don't have an ID of 0 for your normal stuff-objects you can query for this ID:

var stuffToRemove = prods.SingleOrDefault( s => s.ID == 1 )
if( stuffToRemove.ID != 0 )
{
    prods.Remove( stuffToRemove );
}

According to the error message, you declared myLoc as a pointer to an NSInteger (NSInteger *myLoc) rather than an actual NSInteger (NSInteger myLoc). It needs to be the latter.

1) Requires .NET framework 4 updated to at least 4.0.2. If you have 4.0.2, then you should have

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319\SKUs\.NETFramework,Version=v4.0.2

If you have installed latest VS 2012 chances are that you already have 4.0.2. Just verify first.

2) Next you need to have an instance of LocalDb. By default you have an instance whose name is a single v character followed by the LocalDB release version number in the format xx.x. For example, v11.0 represents SQL Server 2012. Automatic instances are public by default. You can also have named instances which are private. Named instances provide isolation from other instances and can improve performance by reducing resource contention with other database users. You can check the status of instances using the SqlLocalDb.exe utility (run it from command line).

3) Next your connection string should look like:

"Server=(localdb)\\v11.0;Integrated Security=true;"

or

"Data Source=(localdb)\\test;Integrated Security=true;"

from your code. They both are the same. Notice the two \\ required because \v and \t means special characters. Also note that what appears after (localdb)\\ is the name of your LocalDb instance. v11.0 is the default public instance, test is something I have created manually which is private.

1. If you have a database (.mdf file) already:

   "Server=(localdb)\\Test;Integrated Security=true;AttachDbFileName= myDbFile;"
   

2. If you don't have a Sql Server database:

   "Server=(localdb)\\v11.0;Integrated Security=true;"
   

And you can create your own database programmatically:

a) to save it in the default location with default setting:

var query = "CREATE DATABASE myDbName;";

b) To save it in a specific location with your own custom settings:

// your db name
string dbName = "myDbName";

// path to your db files:
// ensure that the directory exists and you have read write permission.
string[] files = { Path.Combine(Application.StartupPath, dbName + ".mdf"), 
                   Path.Combine(Application.StartupPath, dbName + ".ldf") };

// db creation query:
// note that the data file and log file have different logical names
var query = "CREATE DATABASE " + dbName +
    " ON PRIMARY" +
    " (NAME = " + dbName + "_data," +
    " FILENAME = '" + files[0] + "'," +
    " SIZE = 3MB," +
    " MAXSIZE = 10MB," +
    " FILEGROWTH = 10%)" +

    " LOG ON" +
    " (NAME = " + dbName + "_log," +
    " FILENAME = '" + files[1] + "'," +
    " SIZE = 1MB," +
    " MAXSIZE = 5MB," +
    " FILEGROWTH = 10%)" +
    ";";

And execute!

A sample table can be loaded into the database with something like:

 @"CREATE TABLE supportContacts 
    (
        id int identity primary key, 
        type varchar(20), 
        details varchar(30)
    );
   INSERT INTO supportContacts
   (type, details)
   VALUES
   ('Email', '[email protected]'),
   ('Twitter', '@sqlfiddle');";

Note that SqlLocalDb.exe utility doesnt give you access to databases, you separately need sqlcmd utility which is sad..

EDIT: moved position of semicolon otherwise error would occur if code was copy/pasted

I have tried the following, with socat:

socat TCP-L:8080,fork,reuseaddr -

And even though I have not made a connection to the socket, I cannot listen twice on the same port, in spite of the reuseaddr option.

I get this message (which I expected before):

2016/02/23 09:56:49 socat[2667] E bind(5, {AF=2 0.0.0.0:8080}, 16): Address already in use

I think you need an additionally query because the charset option in the DSN is actually ignored. see link posted in the comment of the other answer.

Looking at how Drupal 7 is doing it in http://api.drupal.org/api/drupal/includes--database--mysql--database.inc/function/DatabaseConnection_mysql%3A%3A__construct/7:

// Force MySQL to use the UTF-8 character set. Also set the collation, if a
// certain one has been set; otherwise, MySQL defaults to 'utf8_general_ci'
// for UTF-8.
if (!empty($connection_options['collation'])) {
  $this->exec('SET NAMES utf8 COLLATE ' . $connection_options['collation']);
}
else {
  $this->exec('SET NAMES utf8');
}

Okay: weird syntax!

var el: HTMLElement = document.getElementById('content');

fixes the problem. I wonder why the example didn't do this in the first place?

complete code:

class Greeter {
    element: HTMLElement;
    span: HTMLElement;
    timerToken: number;

    constructor (element: HTMLElement) { 
        this.element = element;
        this.element.innerText += "The time is: ";
        this.span = document.createElement('span');
        this.element.appendChild(this.span);
        this.span.innerText = new Date().toUTCString();
    }

    start() {
        this.timerToken = setInterval(() => this.span.innerText = new Date().toUTCString(), 500);
    }

    stop() {
        clearTimeout(this.timerToken);
    }

}

window.onload = () => {
    var el: HTMLElement = document.getElementById('content');
    var greeter = new Greeter(el);
    greeter.start();
};

Why cant you use the finally block?

Like

try {

} catch (Exception e) {

  // THIS WILL EXECUTE IF THERE IS AN EXCEPTION IS THROWN IN THE TRY BLOCK

} finally { 

 // THIS WILL EXECUTE IRRESPECTIVE OF WHETHER AN EXCEPTION IS THROWN WITHIN THE TRY CATCH OR NOT

}

EDIT after question amended:

You can do:

int? returnFromFunction2 = null;
    try {
        returnFromFunction2 = function2();
        return returnFromFunction2.value;
        } catch (Exception e) {

          // THIS WILL EXECUTE IF THERE IS AN EXCEPTION IS THROWN IN THE TRY BLOCK

        } finally { 

        if (returnFromFunction2.HasValue) { // do something with value }

         // THIS WILL EXECUTE IRRESPECTIVE OF WHETHER AN EXCEPTION IS THROWN WITHIN THE TRY CATCH OR NOT

        }

I used jQuery .scroll() function to track the event of the toolbar scroll value using scrollTop. I then used a conditional to determine if it was greater than the value on what I wanted to replace. In the below example it was "Results". If the value was true then the results-label added a class 'fixedSimilarLabel' and the new styles were then taken into account.

    $('.toolbar').scroll(function (e) {
//console.info(e.currentTarget.scrollTop);
    if (e.currentTarget.scrollTop >= 130) {
        $('.results-label').addClass('fixedSimilarLabel');
    }
    else {      
        $('.results-label').removeClass('fixedSimilarLabel');
    }
});

        var orderedCache = new List<TabPage>();
        var orderedEnumerator = container.TabPages.GetEnumerator();
        while (orderedEnumerator.MoveNext()) {
            var current = orderedEnumerator.Current as TabPage;
            if (current != null) {
                orderedCache.Add(current);
            }
        }

                }
            }
        };
    }

Used like this:

    var showOnly = this.TabContainer1.GetTabHider();
    showOnly((tab) => tab.Text != "tabPage1");

Original ordering is retained by retaining a reference to the anonymous function instance.

If you're using oh-my-zsh

Type omz update in the terminal

Note: upgrade_oh_my_zsh is deprecated

you can use -clean parameter while starting eclipse like

C:\eclipse\eclipse.exe -vm "C:\Program Files\Java\jdk1.6.0_24\bin" -clean

You can use sprintf: http://php.net/manual/en/function.sprintf.php

<?php
$num = 4;
$num_padded = sprintf("%02d", $num);
echo $num_padded; // returns 04
?>

It will only add the zero if it's less than the required number of characters.

Edit: As pointed out by @FelipeAls:

When working with numbers, you should use %d (rather than %s), especially when there is the potential for negative numbers. If you're only using positive numbers, either option works fine.

For example:

sprintf("%04s", 10); returns 0010
sprintf("%04s", -10); returns 0-10

Where as:

sprintf("%04d", 10); returns 0010
sprintf("%04d", -10); returns -010

If you look at your XAMPP Control Panel, it's clearly stated that the port to the MySQL server is 3306 - you provided 3360. The 3306 is default, and thus doesn't need to be specified. Even so, the 5th parameter of mysqli_connect() is the port, which is where it should be specified.

You could just remove the port specification altogether, as you're using the default port, making it

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db     = 'test_db13';

There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:

• Add a pause to the batch file so that you can see what is happening before it exits.
  1. Right click on one of the .bat files and select "edit". This will open the file in notepad.
  2. Go to the very end of the file and add a new line by pressing "enter".
  3. type pause.
  4. Save the file.
  5. Run the file again using the same method you did before.

- OR -

• Run the batch file from a static command prompt so the window does not close.
  1. In the folder where the .bat files are located, hold down the "shift" key and right click in the white space.
  2. Select "Open Command Window Here".
  3. You will now see a new command prompt. Type in the name of the batch file and press enter.

Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.

How is the rectangle represented? Three points? Four points? Point, sides and angle? Two points and a side? Something else? Without knowing that, any attempts to answer your question will have only purely academic value.

In any case, for any convex polygon (including rectangle) the test is very simple: check each edge of the polygon, assuming each edge is oriented in counterclockwise direction, and test whether the point lies to the left of the edge (in the left-hand half-plane). If all edges pass the test - the point is inside. If at least one fails - the point is outside.

In order to test whether the point (xp, yp) lies on the left-hand side of the edge (x1, y1) - (x2, y2), you just need to calculate

D = (x2 - x1) * (yp - y1) - (xp - x1) * (y2 - y1)

If D > 0, the point is on the left-hand side. If D < 0, the point is on the right-hand side. If D = 0, the point is on the line.

The previous version of this answer described a seemingly different version of left-hand side test (see below). But it can be easily shown that it calculates the same value.

... In order to test whether the point (xp, yp) lies on the left-hand side of the edge (x1, y1) - (x2, y2), you need to build the line equation for the line containing the edge. The equation is as follows

A * x + B * y + C = 0

where

A = -(y2 - y1)
B = x2 - x1
C = -(A * x1 + B * y1)

Now all you need to do is to calculate

D = A * xp + B * yp + C

If D > 0, the point is on the left-hand side. If D < 0, the point is on the right-hand side. If D = 0, the point is on the line.

However, this test, again, works for any convex polygon, meaning that it might be too generic for a rectangle. A rectangle might allow a simpler test... For example, in a rectangle (or in any other parallelogram) the values of A and B have the same magnitude but different signs for opposing (i.e. parallel) edges, which can be exploited to simplify the test.

The ideal datatype for storing Lat Long values in SQL Server is decimal(9,6)

As others have said, this is at approximately 10cm precision, whilst only using 5 bytes of storage.

e.g. CAST(123.456789 as decimal(9,6)) as [LatOrLong]

Instead of Googling for %02d you should have been searching for sprintf() function.

%02d means "format the integer with 2 digits, left padding it with zeroes", so:

Format  Data   Result
%02d    1      01
%02d    11     11

You can truncate the date part:

select * from table1 where trunc(field1) = to_date('2012-01-01', 'YYYY-MM-DD')

The trouble with this approach is that any index on field1 wouldn't be used due to the function call.

Alternatively (and more index friendly)

select * from table1 
 where field1 >= to_timestamp('2012-01-01', 'YYYY-MM-DD') 
   and field1 < to_timestamp('2012-01-02', 'YYYY-MM-DD')

You can peek into the information_schema schema. It has a list of all tables and all fields that are in a table. You can then run queries using the information that you have gotten from this table.

The tables involved are SCHEMATA, TABLES and COLUMNS. There are foreign keys such that you can build up exactly how the tables are created in a schema.

DateTime.now.new_offset(0)

will work in standard Ruby (i.e. without ActiveSupport).

A var cannot be set to null since it needs to be statically typed.

var foo = null;
// compiler goes: "Huh, what's that type of foo?"

However, you can use this construct to work around the issue:

var foo = (string)null;
// compiler goes: "Ah, it's a string. Nice."

I don't know for sure, but from what I heard you can also use dynamic instead of var. This does not require static typing.

dynamic foo = null;
foo = "hi";

Also, since it was not clear to me from the question if you meant the varkeyword or variables in general: Only references (to classes) and nullable types can be set to null. For instance, you can do this:

string s = null; // reference
SomeClass c = null; // reference
int? i = null; // nullable

But you cannot do this:

int i = null; // integers cannot contain null

With java 8 you can try this:

import org.json.JSONException;
import org.json.JSONObject;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

public class JSONUtil {

    public static JSONObject parseJSONFile(String filename) throws JSONException, IOException {
        String content = new String(Files.readAllBytes(Paths.get(filename)));
        return new JSONObject(content);
    }

    public static void main(String[] args) throws IOException, JSONException {
        String filename = "path/to/file/abc.json";
        JSONObject jsonObject = parseJSONFile(filename);

        //do anything you want with jsonObject
    }
}

Is there are more correct way?

Yes, there is.

LocalDate.now( 
    ZoneId.of( "America/Montreal" ) 
).atStartOfDay(
    ZoneId.of( "America/Montreal" )
)

java.time

Java 8 and later now has the new java.time framework built-in. See Tutorial. Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.

Examples

Some examples follow, using java.time. Note how they specify a time zone. If omitted, your JVM’s current default time zone. That default can vary, even changing at any moment during runtime, so I suggest you specify a time zone explicitly rather than rely implicitly on the default.

Here is an example of date-only, without time-of-day nor time zone.

ZoneId zonedId = ZoneId.of( "America/Montreal" );
LocalDate today = LocalDate.now( zonedId );
System.out.println( "today : " + today );

today : 2015-10-19

Here is an example of getting current date-time.

ZoneId zonedId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.now( zonedId );
System.out.println( "zdt : " + zdt );

When run:

zdt : 2015-10-19T18:07:02.910-04:00[America/Montreal]

First Moment Of The Day

The Question asks for the date-time where the time is set to zero. This assumes the first moment of the day is always the time 00:00:00.0 but that is not always the case. Daylight Saving Time (DST) and perhaps other anomalies mean the day may begin at a different time such as 01:00.0.

Fortunately, java.time has a facility to determine the first moment of a day appropriate to a particular time zone, LocalDate::atStartOfDay. Let's see some code using the LocalDate named today and the ZoneId named zoneId from code above.

ZonedDateTime todayStart = today.atStartOfDay( zoneId );

zdt : 2015-10-19T00:00:00-04:00[America/Montreal]

Interoperability

If you must have a java.util.Date for use with classes not yet updated to work with the java.time types, convert. Call the java.util.Date.from( Instant instant ) method.

java.util.Date date = java.util.Date.from( zdt.toInstant() );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

For me it happened after upgrade nuget packages from one PostSharp version to next one in a big solution (~80 project). I've got compiler errors for projects that have commands in PreBuild events.

'cmd' is not recognized as an internal or external command, operable program or batch file. C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets(1249,5): error MSB3073: The command "cmd /c C:\GitRepos\main\ServiceInterfaces\DEV.Config\PreBuild.cmd ServiceInterfaces" exited with code 9009.

PATH variable was corrupted becoming too long with multiple repeated paths related to PostSharp.Patterns.Diagnostics. When I closed Visual Studio and opened it again, the problem was fixed.

First, you should disable selinux, edit file /etc/sysconfig/selinux so it looks like this:

SELINUX=disabled
SELINUXTYPE=targeted

Save file and restart system.

Then you can add the new rule to iptables:

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

and restart iptables with /etc/init.d/iptables restart

If it doesn't work you should check other network settings.

THERE ARE THREE STEPS:

1) Just use this code segment into your OnCreate method

  // FullScreen
  getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, 
  WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

If you’re working on Fragment, you should put this code segment in your activity’s OnCreate method.

2) Be sure to also set the transparency in /res/values-v21/styles.xml:

<item name="android:statusBarColor">@android:color/transparent</item>

Or you can set the transparency programmatically:

getWindow().setStatusBarColor(Color.TRANSPARENT);

3) In anyway you should add the code segment in styles.xml

<item name="android:windowTranslucentStatus">true</item>

NOTE: This method just works on API 21 and above.

Use:

$ cp -R SRCFOLDER DESTFOLDER/

There are two ways to do it. The direct approach would be to simply call (and print) the strftime() method in your template, for example

{{ car.date_of_manufacture.strftime('%Y-%m-%d') }}

Another, sightly better approach would be to define your own filter, e.g.:

from flask import Flask
import babel

app = Flask(__name__)

@app.template_filter()
def format_datetime(value, format='medium'):
    if format == 'full':
        format="EEEE, d. MMMM y 'at' HH:mm"
    elif format == 'medium':
        format="EE dd.MM.y HH:mm"
    return babel.dates.format_datetime(value, format)

(This filter is based on babel for reasons regarding i18n, but you can use strftime too). The advantage of the filter is, that you can write

{{ car.date_of_manufacture|datetime }}
{{ car.date_of_manufacture|datetime('full') }}

which looks nicer and is more maintainable. Another common filter is also the "timedelta" filter, which evaluates to something like "written 8 minutes ago". You can use babel.dates.format_timedelta for that, and register it as filter similar to the datetime example given here.

It looks like you are calling a non static member (a property or method, specifically setTextboxText) from a static method (specifically SumData). You will need to either:

1. Make the called member static also:

   static void setTextboxText(int result)
   {
       // Write static logic for setTextboxText.  
       // This may require a static singleton instance of Form1.
   }
   

2. Create an instance of Form1 within the calling method:

   private static void SumData(object state)
   {
       int result = 0;
       //int[] icount = (int[])state;
       int icount = (int)state;
   
       for (int i = icount; i > 0; i--)
       {
           result += i;
           System.Threading.Thread.Sleep(1000);
       }
       Form1 frm1 = new Form1();
       frm1.setTextboxText(result);
   }
   

   Passing in an instance of Form1 would be an option also.

3. Make the calling method a non-static instance method (of Form1):

   private void SumData(object state)
   {
       int result = 0;
       //int[] icount = (int[])state;
       int icount = (int)state;
   
       for (int i = icount; i > 0; i--)
       {
           result += i;
           System.Threading.Thread.Sleep(1000);
       }
       setTextboxText(result);
   }
   

More info about this error can be found on MSDN.

For SQL Server 2000, this should tell you only the #temp tables in your session. (Adapted from my example for more modern versions of SQL Server here.) This assumes you don't name your tables with three consecutive underscores, like CREATE TABLE #foo___bar:

SELECT 
  name = SUBSTRING(t.name, 1, CHARINDEX('___', t.name)-1),
  t.id
FROM tempdb..sysobjects AS t
WHERE t.name LIKE '#%[_][_][_]%'
AND t.id = 
  OBJECT_ID('tempdb..' + SUBSTRING(t.name, 1, CHARINDEX('___', t.name)-1));

Actually, you CAN get the whole Bitcoin trades history from Bitcoincharts in CSV format here : http://api.bitcoincharts.com/v1/csv/

it is updated twice a day for active exchanges, and there is a few dead exchanges, too.

EDIT: Since there are no column headers in the CSVs, here's what they are : column 1) the trade's timestamp, column 2) the price, column 3) the volume of the trade

Try sprintf():

char str[12];
int num = 3;
sprintf(str, "%d", num); // str now contains "3"

sprintf() is like printf() but outputs to a string.

Also, as Parappa mentioned in the comments, you might want to use snprintf() to stop a buffer overflow from occuring (where the number you're converting doesn't fit the size of your string.) It works like this:

snprintf(str, sizeof(str), "%d", num);

You could create another object that dispatches calls to magic methods to the underlying objects. Here's how you'd handle __get, but to get it working fully you'd have to override all the relevant magic methods. You'll probably find syntax errors since I just entered it off the top of my head.

class Compositor {
  private $obj_a;
  private $obj_b;

  public function __construct($obj_a, $obj_b) {
    $this->obj_a = $obj_a;
    $this->obj_b = $obj_b;
  }

  public function __get($attrib_name) {
    if ($this->obj_a->$attrib_name) {
       return $this->obj_a->$attrib_name;
    } else {
       return $this->obj_b->$attrib_name;
    }
  }
}

Good luck.

The word "read" is vague, but here is an example which reads a jpeg file using the Image class, and prints information about it.

from PIL import Image
jpgfile = Image.open("picture.jpg")

print(jpgfile.bits, jpgfile.size, jpgfile.format)

It sounds like you have a form tag in a Master Page and in the Page that is throwing the error.

You can have only one.

Another reason could be because the filepath is empty where you are trying to write which is why it can't find it. just another reason why this error occurs.

Build a new list with a list comprehension:

new_items = [x if x % 2 else None for x in items]

You can modify the original list in-place if you want, but it doesn't actually save time:

items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
for index, item in enumerate(items):
    if not (item % 2):
        items[index] = None

Here are (Python 3.6.3) timings demonstrating the non-timesave:

In [1]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: for index, item in enumerate(items):
   ...:     if not (item % 2):
   ...:         items[index] = None
   ...:
1.06 µs ± 33.7 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [2]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: new_items = [x if x % 2 else None for x in items]
   ...:
891 ns ± 13.6 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

And Python 2.7.6 timings:

In [1]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: for index, item in enumerate(items):
   ...:     if not (item % 2):
   ...:         items[index] = None
   ...: 
1000000 loops, best of 3: 1.27 µs per loop
In [2]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: new_items = [x if x % 2 else None for x in items]
   ...: 
1000000 loops, best of 3: 1.14 µs per loop

You can look for regular expression

Regex.IsMatch(str, @"^[a-zA-Z]+$");

Somewhat of an old thread but, this seems to be a faster method using the latest version of matplotlib:

set the major formatter for the x-axis

ax.xaxis.set_major_formatter(plt.NullFormatter())

Just came up with this solution, no VBA needed;

Find the last occurance of "_" in my example;

=IFERROR(FIND(CHAR(1);SUBSTITUTE(A1;"_";CHAR(1);LEN(A1)-LEN(SUBSTITUTE(A1;"_";"")));0)

Explained inside out;

SUBSTITUTE(A1;"_";"") => replace "_" by spaces
LEN( *above* ) => count the chars
LEN(A1)- *above*  => indicates amount of chars replaced (= occurrences of "_")
SUBSTITUTE(A1;"_";CHAR(1); *above* ) => replace the Nth occurence of "_" by CHAR(1) (Nth = amount of chars replaced = the last one)
FIND(CHAR(1); *above* ) => Find the CHAR(1), being the last (replaced) occurance of "_" in our case
IFERROR( *above* ;"0") => in case no chars were found, return "0"

Hope this was helpful.

No, this is not working. And it's not just for you, in case you spent the last hour trying to find an answer for having your embeded videos open in HD.

Question: Oh, but how do you know this is not working anymore and there is no other alternative to make embeded videos open in a different quality?

Answer: Just went to Google's official documentation regarding Youtube's player parameters and there is not a single parameter that allows you to change its quality.

Also, hd=1 doesn't work either. More info here.

Apparently Youtube analyses the width and height of the user's window (or iframe) and automatically sets the quality based on this.

UPDATE:

As of 10 of April of 2018 it still doesn't work (see my comment on the accepted answer for more details).

What I can see from comments is that it MAY work sometimes, but some others it doesn't. The accepted answer states that "it measures the network speed and the screen and player sizes". So, by that, we can understand that I CANNOT force HD as YouTube will still do whatever it wants in case of low network speed/screen resolution. From my perspective everyone saying it works just have false positives on their hands and on the occasion they tested it worked for some random reason not related to the vq parameter. If it was a valid parameter, Google would document it somewhere, and vq isn't documented anywhere.

I converted the code in Anomie's answer here (copy-pasted above by suvish valsan) into Swift:

func fixOrientation() -> UIImage {
    if self.imageOrientation == UIImageOrientation.Up {
        return self
    }

    var transform = CGAffineTransformIdentity

    switch self.imageOrientation {
    case .Down, .DownMirrored:
        transform = CGAffineTransformTranslate(transform, self.size.width, self.size.height)
        transform = CGAffineTransformRotate(transform, CGFloat(M_PI));

    case .Left, .LeftMirrored:
        transform = CGAffineTransformTranslate(transform, self.size.width, 0);
        transform = CGAffineTransformRotate(transform, CGFloat(M_PI_2));

    case .Right, .RightMirrored:
        transform = CGAffineTransformTranslate(transform, 0, self.size.height);
        transform = CGAffineTransformRotate(transform, CGFloat(-M_PI_2));

    case .Up, .UpMirrored:
        break
    }

    switch self.imageOrientation {

    case .UpMirrored, .DownMirrored:
        transform = CGAffineTransformTranslate(transform, self.size.width, 0)
        transform = CGAffineTransformScale(transform, -1, 1)

    case .LeftMirrored, .RightMirrored:
        transform = CGAffineTransformTranslate(transform, self.size.height, 0)
        transform = CGAffineTransformScale(transform, -1, 1);

    default:
        break;
    }

    // Now we draw the underlying CGImage into a new context, applying the transform
    // calculated above.
    let ctx = CGBitmapContextCreate(
        nil,
        Int(self.size.width),
        Int(self.size.height),
        CGImageGetBitsPerComponent(self.CGImage),
        0,
        CGImageGetColorSpace(self.CGImage),
        UInt32(CGImageGetBitmapInfo(self.CGImage).rawValue)
    )

    CGContextConcatCTM(ctx, transform);

    switch self.imageOrientation {
    case .Left, .LeftMirrored, .Right, .RightMirrored:
        // Grr...
        CGContextDrawImage(ctx, CGRectMake(0, 0, self.size.height,self.size.width), self.CGImage);

    default:
        CGContextDrawImage(ctx, CGRectMake(0, 0, self.size.width,self.size.height), self.CGImage);
        break;
    }

    // And now we just create a new UIImage from the drawing context
    let cgimg = CGBitmapContextCreateImage(ctx)

    let img = UIImage(CGImage: cgimg!)

    return img;
}

(I replaced all occurencies of the parameter image with self, because my code is an extension on UIImage).

EDIT: Swift 3 version.

The method returns an optional, because many of the intermediate calls can fail and I don't like to use !.

func fixOrientation() -> UIImage? {

    guard let cgImage = self.cgImage else {
        return nil
    }

    if self.imageOrientation == UIImageOrientation.up {
        return self
    }

    let width  = self.size.width
    let height = self.size.height

    var transform = CGAffineTransform.identity

    switch self.imageOrientation {
    case .down, .downMirrored:
        transform = transform.translatedBy(x: width, y: height)
        transform = transform.rotated(by: CGFloat.pi)

    case .left, .leftMirrored:
        transform = transform.translatedBy(x: width, y: 0)
        transform = transform.rotated(by: 0.5*CGFloat.pi)

    case .right, .rightMirrored:
        transform = transform.translatedBy(x: 0, y: height)
        transform = transform.rotated(by: -0.5*CGFloat.pi)

    case .up, .upMirrored:
        break
    }

    switch self.imageOrientation {
    case .upMirrored, .downMirrored:
        transform = transform.translatedBy(x: width, y: 0)
        transform = transform.scaledBy(x: -1, y: 1)

    case .leftMirrored, .rightMirrored:
        transform = transform.translatedBy(x: height, y: 0)
        transform = transform.scaledBy(x: -1, y: 1)

    default:
        break;
    }

    // Now we draw the underlying CGImage into a new context, applying the transform
    // calculated above.
    guard let colorSpace = cgImage.colorSpace else {
        return nil
    }

    guard let context = CGContext(
        data: nil,
        width: Int(width),
        height: Int(height),
        bitsPerComponent: cgImage.bitsPerComponent,
        bytesPerRow: 0,
        space: colorSpace,
        bitmapInfo: UInt32(cgImage.bitmapInfo.rawValue)
        ) else {
            return nil
    }

    context.concatenate(transform);

    switch self.imageOrientation {

    case .left, .leftMirrored, .right, .rightMirrored:
        // Grr...
        context.draw(cgImage, in: CGRect(x: 0, y: 0, width: height, height: width))

    default:
        context.draw(cgImage, in: CGRect(x: 0, y: 0, width: width, height: height))
    }

    // And now we just create a new UIImage from the drawing context
    guard let newCGImg = context.makeImage() else {
        return nil
    }

    let img = UIImage(cgImage: newCGImg)

    return img;
}

(Note: Swift 3 version odes compile under Xcode 8.1, but haven't tested it actually works. There might be a typo somewhere, mixed up width/height, etc. Feel free to point/fix any errors).

There are already a lot of answers here, but I am surprised no one seems to have suggested using arrays... So here's what I did - this might be useful to some in the future.

n=10 # run 10 jobs
c=0
PIDS=()

while true

    my_function_or_command &
    PID=$!
    echo "Launched job as PID=$PID"
    PIDS+=($PID)

    (( c+=1 ))

    # required to prevent any exit due to error
    # caused by additional commands run which you
    # may add when modifying this example
    true

do

    if (( c < n ))
    then
        continue
    else
        break
    fi
done 


# collect launched jobs

for pid in "${PIDS[@]}"
do
    wait $pid || echo "failed job PID=$pid"
done

In classic sh, you have to do something like:

s=test1
s="${s}test2"

(there are lots of variations on that theme, like s="$s""test2")

In bash, you can use +=:

s=test1
s+=test2

An excellent explanation of the uses of the underscore is Scala _ [underscore] magic.

Examples:

 def matchTest(x: Int): String = x match {
     case 1 => "one"
     case 2 => "two"
     case _ => "anything other than one and two"
 }

 expr match {
     case List(1,_,_) => " a list with three element and the first element is 1"
     case List(_*)  => " a list with zero or more elements "
     case Map[_,_] => " matches a map with any key type and any value type "
     case _ =>
 }

 List(1,2,3,4,5).foreach(print(_))
 // Doing the same without underscore: 
 List(1,2,3,4,5).foreach( a => print(a))

In Scala, _ acts similar to * in Java while importing packages.

// Imports all the classes in the package matching
import scala.util.matching._

// Imports all the members of the object Fun (static import in Java).
import com.test.Fun._

// Imports all the members of the object Fun but renames Foo to Bar
import com.test.Fun.{ Foo => Bar , _ }

// Imports all the members except Foo. To exclude a member rename it to _
import com.test.Fun.{ Foo => _ , _ }

In Scala, a getter and setter will be implicitly defined for all non-private vars in a object. The getter name is same as the variable name and _= is added for the setter name.

class Test {
    private var a = 0
    def age = a
    def age_=(n:Int) = {
            require(n>0)
            a = n
    }
}

Usage:

val t = new Test
t.age = 5
println(t.age)

If you try to assign a function to a new variable, the function will be invoked and the result will be assigned to the variable. This confusion occurs due to the optional braces for method invocation. We should use _ after the function name to assign it to another variable.

class Test {
    def fun = {
        // Some code
    }
    val funLike = fun _
}

Thanks for that info on the ControlToValidate LukeH!

What I was trying to do in my code was to only ensure that some text field A has some text in the field when text field B has a particular value. Otherwise, A can be blank or whatever else. Getting rid of the ControlToValidate="A" in my mark up fixed the issue for me.

Cheers!

If you need special behaviors like nested object extension or array replacement you can use Node.js's extendify.

var extendify = require('extendify');

_.extend = extendify({
    inPlace: false,
    arrays : 'replace',
    isDeep: true
});

obj1 = {
    a:{
        arr: [1,2]
    },
    b: 4
};

obj2 = {
    a:{
        arr: [3]
    }
};

res = _.extend(obj1,obj2);
console.log(JSON.stringify(res)); //{'a':{'arr':[3]},'b':4}

You can use the DataFrame method .apply() to operate on the values in Mycol:

>>> df = pd.DataFrame(['05SEP2014:00:00:00.000'],columns=['Mycol'])
>>> df
                    Mycol
0  05SEP2014:00:00:00.000
>>> import datetime as dt
>>> df['Mycol'] = df['Mycol'].apply(lambda x: 
                                    dt.datetime.strptime(x,'%d%b%Y:%H:%M:%S.%f'))
>>> df
       Mycol

Is this a simple eclipse java project without maven etc? In that case you will need to put the log4j2.xml file under src folder in order to be able to find it on the classpath. If you use maven put it under src/main/resources or src/test/resources

The best and the easiest way, for me was this..

->Simply create a thread with Handler containing sleep().

private ImageView myImageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_shape_count); myImageView= (ImageView)findViewById(R.id.shape1);
    Animation myFadeInAnimation = AnimationUtils.loadAnimation(this, R.anim.fadein);
    myImageView.startAnimation(myFadeInAnimation);

    new Thread(new Runnable() {
        private Handler handler = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                Log.w("hendler", "recived");
                    Animation myFadeOutAnimation = AnimationUtils.loadAnimation(getBaseContext(), R.anim.fadeout);
                    myImageView.startAnimation(myFadeOutAnimation);
                    myImageView.setVisibility(View.INVISIBLE);
            }
        };

        @Override
        public void run() {
            try{
                Thread.sleep(2000); // your fadein duration
            }catch (Exception e){
            }
            handler.sendEmptyMessage(1);

        }
    }).start();
}

Use fileReader.readAsDataURL( fileObject ), this will encode it to base64, which you can safely upload to your server.

The significant differences between the two methods are the class of the objects they return when used for extraction and whether they may accept a range of values, or just a single value during assignment.

Consider the case of data extraction on the following list:

foo <- list( str='R', vec=c(1,2,3), bool=TRUE )

Say we would like to extract the value stored by bool from foo and use it inside an if() statement. This will illustrate the differences between the return values of [] and [[]] when they are used for data extraction. The [] method returns objects of class list (or data.frame if foo was a data.frame) while the [[]] method returns objects whose class is determined by the type of their values.

So, using the [] method results in the following:

if( foo[ 'bool' ] ){ print("Hi!") }
Error in if (foo["bool"]) { : argument is not interpretable as logical

class( foo[ 'bool' ] )
[1] "list"

This is because the [] method returned a list and a list is not valid object to pass directly into an if() statement. In this case we need to use [[]] because it will return the "bare" object stored in 'bool' which will have the appropriate class:

if( foo[[ 'bool' ]] ){ print("Hi!") }
[1] "Hi!"

class( foo[[ 'bool' ]] )
[1] "logical"

The second difference is that the [] operator may be used to access a range of slots in a list or columns in a data frame while the [[]] operator is limited to accessing a single slot or column. Consider the case of value assignment using a second list, bar():

bar <- list( mat=matrix(0,nrow=2,ncol=2), rand=rnorm(1) )

Say we want to overwrite the last two slots of foo with the data contained in bar. If we try to use the [[]] operator, this is what happens:

foo[[ 2:3 ]] <- bar
Error in foo[[2:3]] <- bar : 
more elements supplied than there are to replace

This is because [[]] is limited to accessing a single element. We need to use []:

foo[ 2:3 ] <- bar
print( foo )

$str
[1] "R"

$vec
     [,1] [,2]
[1,]    0    0
[2,]    0    0

$bool
[1] -0.6291121

Note that while the assignment was successful, the slots in foo kept their original names.

Go to wherever you installed Android Studio (for me it's under C:\Users\username\AppData\Local\Android\android-studio\) and open sdk\tools, then run android.bat. From here, update and download any missing build-tools and make sure you update the Android Support Repository and Android Support Library under Extras. Restart Android Studio after the SDK Manager finishes.

It seems that Android Studio completely ignores any installed Android SDK files and keeps a copy of its own. After running an update, everything compiled successfully for me using compile com.android.support:appcompat-v7:18.0.+

I'd venture that the safest is to use String.Equals to mitigate against the possibility that val is null.

You can easily use .replace() as also previously described. But it is also important to keep in mind that strings are immutable. Hence if you do not assign the change you are making to a variable, then you will not see any change. Let me explain by;

    >>stuff = "bin and small"
    >>stuff.replace('and', ',')
    >>print(stuff)
    "big and small" #no change

To observe the change you want to apply, you can assign same or another variable;

    >>stuff = "big and small"
    >>stuff = stuff.replace("and", ",")   
    >>print(stuff)
    'big, small'

Try this query (replace t.eventsDate with e.eventsDate):

SELECT e FROM Events e WHERE e.eventsDate BETWEEN :startDate AND :endDate

• The try block will execute a sensitive code which can throw exceptions
• The catch block will be used whenever an exception (of the type caught) is thrown in the try block
• The finally block is called in every case after the try/catch blocks. Even if the exception isn't caught or if your previous blocks break the execution flow.
• The throw keyword will allow you to throw an exception (which will break the execution flow and can be caught in a catch block).
• The throws keyword in the method prototype is used to specify that your method might throw exceptions of the specified type. It's useful when you have checked exception (exception that you have to handle) that you don't want to catch in your current method.
