The answers here are outdated. Now you can easily use a CSS3 transform without hardcoding a margin. This works on all elements, including elements with no width or dynamic width.

Horizontal center:

left: 50%;
transform: translateX(-50%);

Vertical center:

top: 50%;
transform: translateY(-50%);

Both horizontal and vertical:

left: 50%;
top: 50%;
transform: translate(-50%, -50%);

Compatibility is not an issue: http://caniuse.com/#feat=transforms2d

For those still not able to set JAVA_HOME from Android Studio installation, for me the path was actually not in C:\...\Android Studio\jre

but rather in the ...\Android Studio\jre\jre.

Don't ask me why though.

There are a few places you can do versioning in a REST API:

1. As noted, in the URI. This can be tractable and even esthetically pleasing if redirects and the like are used well.

2. In the Accepts: header, so the version is in the filetype. Like 'mp3' vs 'mp4'. This will also work, though IMO it works a bit less nicely than...

3. In the resource itself. Many file formats have their version numbers embedded in them, typically in the header; this allows newer software to 'just work' by understanding all existing versions of the filetype while older software can punt if an unsupported (newer) version is specified. In the context of a REST API, it means that your URIs never have to change, just your response to the particular version of data you were handed.

I can see reasons to use all three approaches:

1. if you like doing 'clean sweep' new APIs, or for major version changes where you want such an approach.
2. if you want the client to know before it does a PUT/POST whether it's going to work or not.
3. if it's okay if the client has to do its PUT/POST to find out if it's going to work.

On the Linux system you can do following (Should be similar for other OS)

Check if mysql process is running:

sudo service mysql status

If runnning then stop the process: (Make sure you close all mysql tool)

sudo service mysql stop

If you have issue stopping then do following

Search for process: ps aux | grep mysqld Kill the process: kill -9 process_id

Now start mysql in safe mode with skip grant

sudo mysqld_safe --skip-grant-tables &

you could use an Entity:

FileEntity entity = new FileEntity(jsonFile, "application/json");
String jsonString = EntityUtils.toString(entity)

For folks that are here looking for a solution for images in particular here it is.

private Bitmap getBitmapFromUri(Uri contentUri) {
        String path = null;
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = getContentResolver().query(contentUri, projection, null, null, null);
        if (cursor.moveToFirst()) {
            int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
            path = cursor.getString(columnIndex);
        }
        cursor.close();
        Bitmap bitmap = BitmapFactory.decodeFile(path);
        return bitmap;
    }

Last month I tried to configure iptables on a LXC VM container, but every time after reboot the iptables configuration was not automatically loaded.

The only way for me to get it working was by running the following command:

yum -y install iptables-services; systemctl disable firewalld; systemctl mask firewalld; service iptables restart; service iptables save

if you are trying to use jquery in your electron app before adding jquery you should add it to your modules:

<script>
    if (typeof module === 'object') {
        window.module = module;
        module = undefined;
    }
</script>
<script src="js/jquery-3.5.1.min.js"></script>

If it's really important that you have the correct date and time; it's best to have a service on your server (which you of course have running in UTC) that returns the time. You can then create a new Date on the client and compare the values and if necessary adjust all dates with the offset from the server time.

Why do this? I've had bug reports that was hard to reproduce because I could not find the error messages in the server log, until I noticed that the bug report was mailed two days after I'd received it. You can probably trust the browser to correctly handle time-zone conversion when being sent a UTC timestamp, but you obviously cannot trust the users to have their system clock correctly set. (If the users have their timezone incorrectly set too, there is not really any solution; other than printing the current server time in "local" time)

You can use the workbook.get_worksheet_by_name() feature: https://xlsxwriter.readthedocs.io/workbook.html#get_worksheet_by_name

According to https://xlsxwriter.readthedocs.io/changes.html the feature has been added on May 13, 2016.

"Release 0.8.7 - May 13 2016

-Fix for issue when inserting read-only images on Windows. Issue #352.

-Added get_worksheet_by_name() method to allow the retrieval of a worksheet from a workbook via its name.

-Fixed issue where internal file creation and modification dates were in the local timezone instead of UTC."

You can use the following command to see if a service is running or not:

sc query [ServiceName] | findstr /i "STATE"

When I run it for my NOD32 Antivirus, I get:

STATE                       : 4 RUNNING

If it was stopped, I would get:

STATE                       : 1 STOPPED

You can use this in a variable to then determine whether you use NET START or not.

The service name should be the service name, not the display name.

Create is_number? Method.

Create a helper method:

def is_number? string
  true if Float(string) rescue false
end

And then call it like this:

my_string = '12.34'

is_number?( my_string )
# => true

Extend String Class.

If you want to be able to call is_number? directly on the string instead of passing it as a param to your helper function, then you need to define is_number? as an extension of the String class, like so:

class String
  def is_number?
    true if Float(self) rescue false
  end
end

And then you can call it with:

my_string.is_number?
# => true

For users using CoffeeScript, you can use a range comprehension:

Directive

link: (scope, element, attrs) ->
  scope.range = [1..+attrs.range]

or Controller

$scope.range = [1..+$someVariable]
$scope.range = [1..5] # Or just an integer

Template

<div ng-repeat="i in range">[ the rest of your code ]</div>

Make sure you really need to invert the matrix. This is often unnecessary and can be numerically unstable. When most people ask how to invert a matrix, they really want to know how to solve Ax = b where A is a matrix and x and b are vectors. It's more efficient and more accurate to use code that solves the equation Ax = b for x directly than to calculate A inverse then multiply the inverse by B. Even if you need to solve Ax = b for many b values, it's not a good idea to invert A. If you have to solve the system for multiple b values, save the Cholesky factorization of A, but don't invert it.

See Don't invert that matrix.

tl;dr

Import the root module with importlib.import_module and load the class by its name using getattr function:

# Standard import
import importlib
# Load "module.submodule.MyClass"
MyClass = getattr(importlib.import_module("module.submodule"), "MyClass")
# Instantiate the class (pass arguments to the constructor, if needed)
instance = MyClass()

explanations

You probably don't want to use __import__ to dynamically import a module by name, as it does not allow you to import submodules:

>>> mod = __import__("os.path")
>>> mod.join
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'join'

Here is what the python doc says about __import__:

Note: This is an advanced function that is not needed in everyday Python programming, unlike importlib.import_module().

Instead, use the standard importlib module to dynamically import a module by name. With getattr you can then instantiate a class by its name:

import importlib
my_module = importlib.import_module("module.submodule")
MyClass = getattr(my_module, "MyClass")
instance = MyClass()

You could also write:

import importlib
module_name, class_name = "module.submodule.MyClass".rsplit(".", 1)
MyClass = getattr(importlib.import_module(module_name), class_name)
instance = MyClass()

This code is valid in python = 2.7 (including python 3).

Use a JSON library to parse the string and retrieve the value.

The following very basic example uses the built-in JSON parser from Android.

String jsonString = "{ \"name\" : \"John\", \"age\" : \"20\", \"address\" : \"some address\" }";
JSONObject jsonObject = new JSONObject(jsonString);
int age = jsonObject.getInt("age");

More advanced JSON libraries, such as jackson, google-gson, json-io or genson, allow you to convert JSON objects to Java objects directly.

I'd stay with two different interfaces.

You said that 'I want to group my service executors under a common interface... It also seems overkill creating two separate interfaces for the two different service calls... A class will only implement one of these interfaces'

It's not clear what is the reason to have a single interface then. If you want to use it as a marker, you can just exploit annotations instead.

Another point is that there is a possible case that your requirements change and method(s) with another signature appears at the interface. Of course it's possible to use Adapter pattern then but it would be rather strange to see that particular class implements interface with, say, three methods where two of them trow UnsupportedOperationException. It's possible that the forth method appears etc.

Have a look at Spring framework source, it has excellent javadocs

append 0 before it by checking if the value falls between 1 and 9 by first casting it to varchar

select case when DATEPART(month, getdate()) between 1 and 9 
then '0' else '' end + cast(DATEPART(month, getdate()) as varchar(2))

well, you can very quickly test the click dispatch via jQuery like so

$('#link-id').click();

If you're still having problem with click respecting the target, you can always do this

$('#link-id').click( function( event, anchor )
{
  window.open( anchor.href, anchor.target, '' );
  event.preventDefault();
  return false;
});

Another mean to repeat an arbitrary string n times:

Pros:

• Works with POSIX shell.
• Output can be assigned to a variable.
• Repeats any string.
• Very fast even with very large repeats.

Cons:

• Requires Gnu Core Utils's yes command.

#!/usr/bin/sh
to_repeat='='
repeat_count=80
yes "$to_repeat" | tr -d '\n' | head -c "$repeat_count"

With an ANSI terminal and US-ASCII characters to repeat. You can use an ANSI CSI escape sequence. It is the fastest way to repeat a character.

#!/usr/bin/env bash

char='='
repeat_count=80
printf '%c\e[%db' "$char" "$repeat_count"

Or statically:

Print a line of 80 times =:

printf '=\e[80b\n'

Limitations:

• Not all terminals understands the repeat_char ANSI CSI sequence.
• Only US-ASCII or single-byte ISO characters can be repeated.
• Repeat stops at last column, so you can use a large value to fill a whole line regardless of terminal width.
• The repeat is only for display. Capturing output into a shell variable will not expand the repeat_char ANSI CSI sequence into the repeated character.

public class MyProp<T>
{
...
}

public class ClassThatUsesMyProp
{
public MyProp<String> SomeProperty { get; set; }
}

Here's a version that will handle a non-scalar "values" array:

import numpy as np

def find_nearest(array, values):
    indices = np.abs(np.subtract.outer(array, values)).argmin(0)
    return array[indices]

Or a version that returns a numeric type (e.g. int, float) if the input is scalar:

def find_nearest(array, values):
    values = np.atleast_1d(values)
    indices = np.abs(np.subtract.outer(array, values)).argmin(0)
    out = array[indices]
    return out if len(out) > 1 else out[0]

It seems that if

• Content-Type: application/json and
• if POST body isn't tightly bound to controller's input object class

Then MVC doesn't really bind the POST body to any particular class. Nor can you just fetch the POST body as a param of the ActionResult (suggested in another answer). Fair enough. You need to fetch it from the request stream yourself and process it.

[HttpPost]
public ActionResult Index(int? id)
{
    Stream req = Request.InputStream;
    req.Seek(0, System.IO.SeekOrigin.Begin);
    string json = new StreamReader(req).ReadToEnd();

    InputClass input = null;
    try
    {
        // assuming JSON.net/Newtonsoft library from http://json.codeplex.com/
        input = JsonConvert.DeserializeObject<InputClass>(json)
    }

    catch (Exception ex)
    {
        // Try and handle malformed POST body
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }

    //do stuff

}

Update:

for Asp.Net Core, you have to add [FromBody] attrib beside your param name in your controller action for complex JSON data types:

[HttpPost]
public ActionResult JsonAction([FromBody]Customer c)

Also, if you want to access the request body as string to parse it yourself, you shall use Request.Body instead of Request.InputStream:

Stream req = Request.Body;
req.Seek(0, System.IO.SeekOrigin.Begin);
string json = new StreamReader(req).ReadToEnd();

It happens because Build Tools revision 24.4.1 doesn't exist.

The latest version is 23.0.2.
These tools is included in the SDK package and installed in the <sdk>/build-tools/ directory.

Don't confuse the Android SDK Tools with SDK Build Tools.

Change in your build.gradle

android {
   buildToolsVersion "23.0.2"
   // ...

}

I prefer to use

<input type='date' id='hasta' value='<?php echo date('Y-m-d');?>'>

that works well

This likely goes back to the core concept that there should be one obvious way to do a task. Additional comment styles add unnecessary complications and could decrease readability.

I used AutoIt to do it.

using AutoIt;
AutoItX.MouseClick("LEFT",150,150,1,0);//1: click once, 0: Move instantaneous

1. Pro:
   • simple
   • regardless of mouse movement
2. Con:
   • since coordinate is screen-based, there should be some caution if the app scales.
   • the drive won't know when the app finish with clicking consequence actions. There should be a waiting period.

Uncheck the marked check, it will enable the grid edit

Do this :

<script type="text/javascript">
function showDetails(username)
{
   window.location = '/player_detail?username='+username;
}
</script>

<input type="button" name="theButton" value="Detail" onclick="showDetails('username');">

Here's how you can do it by using loops.

public static int[][] makeCopy(int[][] array){
    b=new int[array.length][];

    for(int row=0; row<array.length; ++row){
        b[row]=new int[array[row].length];
        for(int col=0; col<b[row].length; ++col){
            b[row][col]=array[row][col];
        }
    }
    return b;
}

See these test cases http://jsperf.com/last-item-method The most effective way is throug .pop method (in V8), but loses the last element of the array

Xcode 9 introduced new tricks with XCTWaiter

Test case waits explicitly

wait(for: [documentExpectation], timeout: 10)

Waiter instance delegates to test

XCTWaiter(delegate: self).wait(for: [documentExpectation], timeout: 10)

Waiter class returns result

let result = XCTWaiter.wait(for: [documentExpectation], timeout: 10)
switch(result) {
case .completed:
    //all expectations were fulfilled before timeout!
case .timedOut:
    //timed out before all of its expectations were fulfilled
case .incorrectOrder:
    //expectations were not fulfilled in the required order
case .invertedFulfillment:
    //an inverted expectation was fulfilled
case .interrupted:
    //waiter was interrupted before completed or timedOut
}

sample usage

Before Xcode 9

Objective C

- (void)waitForElementToAppear:(XCUIElement *)element withTimeout:(NSTimeInterval)timeout
{
    NSUInteger line = __LINE__;
    NSString *file = [NSString stringWithUTF8String:__FILE__];
    NSPredicate *existsPredicate = [NSPredicate predicateWithFormat:@"exists == true"];

    [self expectationForPredicate:existsPredicate evaluatedWithObject:element handler:nil];

    [self waitForExpectationsWithTimeout:timeout handler:^(NSError * _Nullable error) {
        if (error != nil) {
            NSString *message = [NSString stringWithFormat:@"Failed to find %@ after %f seconds",element,timeout];
            [self recordFailureWithDescription:message inFile:file atLine:line expected:YES];
        }
    }];
}

USAGE

XCUIElement *element = app.staticTexts["Name of your element"];
[self waitForElementToAppear:element withTimeout:5];

Swift

func waitForElementToAppear(element: XCUIElement, timeout: NSTimeInterval = 5,  file: String = #file, line: UInt = #line) {
        let existsPredicate = NSPredicate(format: "exists == true")

        expectationForPredicate(existsPredicate,
                evaluatedWithObject: element, handler: nil)

        waitForExpectationsWithTimeout(timeout) { (error) -> Void in
            if (error != nil) {
                let message = "Failed to find \(element) after \(timeout) seconds."
                self.recordFailureWithDescription(message, inFile: file, atLine: line, expected: true)
            }
        }
    }

USAGE

let element = app.staticTexts["Name of your element"]
self.waitForElementToAppear(element)

or

let element = app.staticTexts["Name of your element"]
self.waitForElementToAppear(element, timeout: 10)

Open your php.ini file use CNTRL+F to search for the following settings which may be the culprit:

• file_uploads
• upload_max_filesize
• post_max_size
• memory_limit
• max_input_time
• max_execution_time

Make sure to save a copy of the php.ini prior to making changes. You will want to adjust the settings to accommodate your file size, and increase input and/or execution time.

Remember to restart your services after making changes.

Warning! There may be some unforeseen drawbacks if you adjust these settings too liberally. I am not expert enough to know this for sure.

I was able to make parent window disable. However making the pop-up always keep raised didn't work. Below code works even for frame tags. Just add id and class property to frame tag and it works well there too.

In parent window use:

<head>    
<style>
.disableWin{
     pointer-events: none;
}
</style>
<script type="text/javascript">
    function openPopUp(url) {
      disableParentWin(); 
      var win = window.open(url);
      win.focus();
      checkPopUpClosed(win);
    }
    /*Function to detect pop up is closed and take action to enable parent window*/
   function checkPopUpClosed(win) {
         var timer = setInterval(function() {
              if(win.closed) {
                  clearInterval(timer);                  
                  enableParentWin();
              }
          }, 1000);
     }
     /*Function to enable parent window*/ 
     function enableParentWin() {
          window.document.getElementById('mainDiv').class="";
     }
     /*Function to enable parent window*/ 
     function disableParentWin() {
          window.document.getElementById('mainDiv').class="disableWin";
     }

Content insets solve the problem of having content that goes underneath other parts of the User Interface and yet still remains reachable using scroll bars. In other words, the purpose of the Content Inset is to make the interaction area smaller than its actual area.

Consider the case where we have three logical areas of the screen:

TOP BUTTONS

TEXT

BOTTOM TAB BAR

and we want the TEXT to never appear transparently underneath the TOP BUTTONS, but we want the Text to appear underneath the BOTTOM TAB BAR and yet still allow scrolling so we could update the text sitting transparently under the BOTTOM TAB BAR.

Then we would set the top origin to be below the TOP BUTTONS, and the height to include the bottom of BOTTOM TAB BAR. To gain access to the Text sitting underneath the BOTTOM TAB BAR content we would set the bottom inset to be the height of the BOTTOM TAB BAR.

Without the inset, the scroller would not let you scroll up the content enough to type into it. With the inset, it is as if the content had extra "BLANK CONTENT" the size of the content inset. Blank text has been "inset" into the real "content" -- that's how I remember the concept.

$.fn.scrollEnd = function(callback, timeout) {          
  $(this).scroll(function(){
    var $this = $(this);
    if ($this.data('scrollTimeout')) {
      clearTimeout($this.data('scrollTimeout'));
    }
    $this.data('scrollTimeout', setTimeout(callback,timeout));
  });
};

$(window).scroll(function(){
    $('.main').fadeOut();
});

$(window).scrollEnd(function(){
    $('.main').fadeIn();
}, 700);

That should do the Trick!

This line is your problem:

litersOfPetrol = Float.parseFloat(df.format(litersOfPetrol));

There you formatted your float to string as you wanted, but but then that string got transformed again to a float, and then what you printed in stdout was your float that got a standard formatting. Take a look at this code

import java.text.DecimalFormat;

String stringLitersOfPetrol = "123.00";
System.out.println("string liters of petrol putting in preferences is "+stringLitersOfPetrol);
Float litersOfPetrol=Float.parseFloat(stringLitersOfPetrol);
DecimalFormat df = new DecimalFormat("0.00");
df.setMaximumFractionDigits(2);
stringLitersOfPetrol = df.format(litersOfPetrol);
System.out.println("liters of petrol before putting in editor : "+stringLitersOfPetrol);

And by the way, when you want to use decimals, forget the existence of double and float as others suggested and just use BigDecimal object, it will save you a lot of headache.

I was facing the same issue. I was trying to build linux application for Cyclone V FPGA-SoC. I faced the problem as below:

Error: <application_name> uses VFP register arguments, main.o does not

I was using the toolchain arm-linux-gnueabihf-g++ provided by embedded software design tool of altera.

It is solved by exporting: mfloat-abi=hard to flags, then arm-linux-gnueabihf-g++ compiles without errors. Also include the flags in both CC & LD.

https://socket.io/docs/#What-Socket-IO-is-not (with my emphasis)

What Socket.IO is not

Socket.IO is NOT a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the packet id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server either. Please see the protocol specification here.

// WARNING: the client will NOT be able to connect!
const client = io('ws://echo.websocket.org');

While, this is not technically what you want, if you know before hand the type of object you want to handle you can use the call/apply methods of the prototype of your known object.

you can change this

alert(fooJSON.test() ); //Prints 12

to this

alert(Foo.prototype.test.call(fooJSON); //Prints 12

Splice is the best to remove element from specific index. The given example is tested on console.

card = [1, 2, 3, 4];
card.splice(1,1);  // [2]
card   // (3) [1, 3, 4]
splice(startingIndex, totalNumberOfElements)

startingIndex start from 0.

You can simply delete the /var/mail/username file to delete all emails for a specific user. Also, emails that are outgoing but have not yet been sent will be stored in /var/spool/mqueue.

You need only one line before the declaration of the class Animal for correct polymorphic serialization/deserialization:

@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@class")
public abstract class Animal {
   ...
}

This line means: add a meta-property on serialization or read a meta-property on deserialization (include = JsonTypeInfo.As.PROPERTY) called "@class" (property = "@class") that holds the fully-qualified Java class name (use = JsonTypeInfo.Id.CLASS).

So, if you create a JSON directly (without serialization) remember to add the meta-property "@class" with the desired class name for correct deserialization.

Unfortunately, it is not possible to "get" the height of an element via CSS because CSS is not a language that returns any sort of data other than rules for the browser to adjust its styling.

Your resolution can be achieved with jQuery, or alternatively, you can fake it with CSS3's transform:translateY(); rule.

The CSS Route

If we assume that your target div in this instance is 200px high - this would mean that you want the div to have a margin of 190px?

This can be achieved by using the following CSS:

.dynamic-height {
    -webkit-transform: translateY(100%); //if your div is 200px, this will move it down by 200px, if it is 100px it will down by 100px etc
    transform: translateY(100%);         //if your div is 200px, this will move it down by 200px, if it is 100px it will down by 100px etc
    margin-top: -10px;
}

In this instance, it is important to remember that translateY(100%) will move the element in question downwards by a total of it's own length.

The problem with this route is that it will not push element below it out of the way, where a margin would.

The jQuery Route

If faking it isn't going to work for you, then your next best bet would be to implement a jQuery script to add the correct CSS for you.

jQuery(document).ready(function($){ //wait for the document to load
    $('.dynamic-height').each(function(){ //loop through each element with the .dynamic-height class
        $(this).css({
            'margin-top' : $(this).outerHeight() - 10 + 'px' //adjust the css rule for margin-top to equal the element height - 10px and add the measurement unit "px" for valid CSS
        });
    });
});

use:

my_function({width:12});

Instead of:

my_function(width:12);

In order to uninstall miniconda, simply remove the miniconda folder,

rm -r ~/miniconda/

As for avoiding conflicts between different Python environments, you can use virtual environments. In particular, with Miniconda, the following workflow could be used,

$ wget https://repo.continuum.io/miniconda/Miniconda3-3.7.0-Linux-x86_64.sh -O ~/miniconda.sh
$ bash miniconda
$ conda env remove --yes -n new_env    # remove the environement new_env if it exists (optional)
$ conda create --yes -n new_env pip numpy pandas scipy matplotlib scikit-learn nltk ipython-notebook seaborn python=2
$ activate new_env
$ # pip install modules if needed, run python scripts, etc
  # everything will be installed in the new_env
  # located in ~/miniconda/envs/new_env
$ deactivate

EDIT: Reference to an updated solution by LightMan

See LightMan's solution. Until now I was using:

input.action = { [weak self] value in
    guard let this = self else { return }
    this.someCall(value) // 'this' isn't nil
}

Or:

input.action = { [weak self] value in
    self?.someCall(value) // call is done if self isn't nil
}

Usually you don't need to specify the parameter type if it's inferred.

You can omit the parameter altogether if there is none or if you refer to it as $0 in the closure:

input.action = { [weak self] in
    self?.someCall($0) // call is done if self isn't nil
}

Just for completeness; if you're passing the closure to a function and the parameter is not @escaping, you don't need a weak self:

[1,2,3,4,5].forEach { self.someCall($0) }

I manged to set the MinDate & the MaxDate programmatically like this :

    final Calendar c = Calendar.getInstance();

    int maxYear = c.get(Calendar.YEAR) - 20; // this year ( 2011 ) - 20 = 1991
    int maxMonth = c.get(Calendar.MONTH);
    int maxDay = c.get(Calendar.DAY_OF_MONTH);

    int minYear = 1960;
    int minMonth = 0; // january
    int minDay = 25;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.create_account);
        BirthDateDP = (DatePicker) findViewById(R.id.create_account_BirthDate_DatePicker);
        BirthDateDP.init(maxYear - 10, maxMonth, maxDay, new OnDateChangedListener()
        {

        @Override
        public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth)
        {
            if (year < minYear)
                view.updateDate(minYear, minMonth, minDay);

                if (monthOfYear < minMonth && year == minYear)
                view.updateDate(minYear, minMonth, minDay);

                if (dayOfMonth < minDay && year == minYear && monthOfYear == minMonth)
                view.updateDate(minYear, minMonth, minDay);


                if (year > maxYear)
                view.updateDate(maxYear, maxMonth, maxDay);

                if (monthOfYear > maxMonth && year == maxYear)
                view.updateDate(maxYear, maxMonth, maxDay);

                if (dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth)
                view.updateDate(maxYear, maxMonth, maxDay);
        }}); // BirthDateDP.init()
    } // activity

it works fine for me, enjoy :)

just setting the multiDexEnabled to true worked fine.

    defaultConfig 
    {
        multiDexEnabled true     
    }

The original idea comes from groovy. It was proposed for Java 7 as part of Project Coin: https://wiki.openjdk.java.net/display/Coin/2009+Proposals+TOC (Elvis and Other Null-Safe Operators), but hasn't been accepted yet.

The related Elvis operator ?: was proposed to make x ?: y shorthand for x != null ? x : y, especially useful when x is a complex expression.

from your query:

Select employee_id, count(*) From Employee 
Where to_char(employee_date_hired, 'DD-MON-YY') > '31-DEC-95' 

i think its not to display the number of employees that are hired after June 20, 1994. if you want show number of employees, you can use:

Select count(*) From Employee 
Where to_char(employee_date_hired, 'YYYMMMDDD') > 19940620 

I think for best practice to compare dates you can use:

employee_date_hired > TO_DATE('20-06-1994', 'DD-MM-YYYY');
or
to_char(employee_date_hired, 'YYYMMMDDD') > 19940620;

You can take the SelectedItem and cast it back to your class and access its properties.

 MessageBox.Show(((ComboboxItem)ComboBox_Countries_In_Silvers.SelectedItem).Value);

Edit You can try using DataTextField and DataValueField, I used it with DataSource.

ComboBox_Servers.DataTextField = "Text";
ComboBox_Servers.DataValueField = "Value";

Adding to above answers, I shall tell using example of an app I released on playstore.

This was the first app I developed when learning android there fore I worked only with activities There are multiple activity pages I think about 12. Most of these had content that could be reused in other pages yet I ended up with a separate activity page for almost every single click on the app. Once I learnt fragments I realised how all reusables could just be implemented and separate fragments and just be used with very few activities. My user may not see any difference, but the same can be done with lesser code besides fragments are light weight, apart from the reusability and modularity they offer.

Full disclosure, I am one of the maintainers of pdfminer.six.

Nowadays, there are multiple api's to extract text from a PDF, depending on your needs. Behind the scenes, all of these api's use the same logic for parsing and analyzing the layout.

(All the examples assume your PDF file is called example.pdf)

Commandline

If you want to extract text just once you can use the commandline tool pdf2txt.py:

$ pdf2txt.py example.pdf

High-level api

If you want to extract text with Python, you can use the high-level api. This approach is the go-to solution if you want to extract text programmatically from many PDF's.

from pdfminer.high_level import extract_text

text = extract_text('example.pdf')

Composable api

There is also a composable api that gives a lot of flexibility in handling the resulting objects. For example, you can implement your own layout algorithm using that. This method is suggested in the other answers, but I would only recommend this when you need to customize the way pdfminer.six behaves.

from io import StringIO

from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.pdfpage import PDFPage
from pdfminer.pdfparser import PDFParser

output_string = StringIO()
with open('example.pdf', 'rb') as in_file:
    parser = PDFParser(in_file)
    doc = PDFDocument(parser)
    rsrcmgr = PDFResourceManager()
    device = TextConverter(rsrcmgr, output_string, laparams=LAParams())
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    for page in PDFPage.create_pages(doc):
        interpreter.process_page(page)

print(output_string.getvalue())

Below is the easy one -

cat countvariable.sh

echo "$@" |awk '{for(i=0;i<=NF;i++); print i-1 }'

Output :

#./countvariable.sh 1 2 3 4 5 6
6
#./countvariable.sh 1 2 3 4 5 6 apple orange
8

'\r' means 'carriage return' and it is similar to '\n' which means 'line break' or more commonly 'new line'

in the old days of typewriters, you would have to move the carriage that writes back to the start of the line, and move the line down in order to write onto the next line.

in the modern computer era we still have this functionality for multiple reasons. but mostly we use only '\n' and automatically assume that we want to start writing from the start of the line, since it would not make much sense otherwise.

however, there are some times when we want to use JUST the '\r' and that would be if i want to write something to an output, and the instead of going down to a new line and writing something else, i want to write something over what i already wrote, this is how many programs in linux or in windows command line are able to have 'progress' information that changes on the same line.

nowadays most systems use only the '\n' to denote a newline. but some systems use both together.

you can see examples of this given in some of the other answers, but the most common are:

• windows ends lines with '\r\n'
• mac ends lines with '\r'
• unix/linux use '\n'

and some other programs also have specific uses for them.

for more information about the history of these characters

A "race condition" exists when multithreaded (or otherwise parallel) code that would access a shared resource could do so in such a way as to cause unexpected results.

Take this example:

for ( int i = 0; i < 10000000; i++ )
{
   x = x + 1; 
}

If you had 5 threads executing this code at once, the value of x WOULD NOT end up being 50,000,000. It would in fact vary with each run.

This is because, in order for each thread to increment the value of x, they have to do the following: (simplified, obviously)

Retrieve the value of x
Add 1 to this value
Store this value to x

Any thread can be at any step in this process at any time, and they can step on each other when a shared resource is involved. The state of x can be changed by another thread during the time between x is being read and when it is written back.

Let's say a thread retrieves the value of x, but hasn't stored it yet. Another thread can also retrieve the same value of x (because no thread has changed it yet) and then they would both be storing the same value (x+1) back in x!

Example:

Thread 1: reads x, value is 7
Thread 1: add 1 to x, value is now 8
Thread 2: reads x, value is 7
Thread 1: stores 8 in x
Thread 2: adds 1 to x, value is now 8
Thread 2: stores 8 in x

Race conditions can be avoided by employing some sort of locking mechanism before the code that accesses the shared resource:

for ( int i = 0; i < 10000000; i++ )
{
   //lock x
   x = x + 1; 
   //unlock x
}

Here, the answer comes out as 50,000,000 every time.

For more on locking, search for: mutex, semaphore, critical section, shared resource.

There are two different methods for iPad and iPhone platforms, so you need to implement both:

• selection handler and

• segue.

  NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
  [self.tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
  
  // Selection handler (for horizontal iPad)
  [self tableView:self.tableView didSelectRowAtIndexPath:indexPath];
  
  // Segue (for iPhone and vertical iPad)
  [self performSegueWithIdentifier:"showDetail" sender:self];
  

I agree with some of the other answers that the best approach is to mock HttpMessageHandler rather than wrap HttpClient. This answer is unique in that it still injects HttpClient, allowing it to be a singleton or managed with dependency injection.

HttpClient is intended to be instantiated once and re-used throughout the life of an application.

(Source).

Mocking HttpMessageHandler can be a little tricky because SendAsync is protected. Here's a complete example, using xunit and Moq.

using System;
using System.Net;
using System.Net.Http;
using System.Threading;
using System.Threading.Tasks;
using Moq;
using Moq.Protected;
using Xunit;
// Use nuget to install xunit and Moq

namespace MockHttpClient {
    class Program {
        static void Main(string[] args) {
            var analyzer = new SiteAnalyzer(Client);
            var size = analyzer.GetContentSize("http://microsoft.com").Result;
            Console.WriteLine($"Size: {size}");
        }

        private static readonly HttpClient Client = new HttpClient(); // Singleton
    }

    public class SiteAnalyzer {
        public SiteAnalyzer(HttpClient httpClient) {
            _httpClient = httpClient;
        }

        public async Task<int> GetContentSize(string uri)
        {
            var response = await _httpClient.GetAsync( uri );
            var content = await response.Content.ReadAsStringAsync();
            return content.Length;
        }

        private readonly HttpClient _httpClient;
    }

    public class SiteAnalyzerTests {
        [Fact]
        public async void GetContentSizeReturnsCorrectLength() {
            // Arrange
            const string testContent = "test content";
            var mockMessageHandler = new Mock<HttpMessageHandler>();
            mockMessageHandler.Protected()
                .Setup<Task<HttpResponseMessage>>("SendAsync", ItExpr.IsAny<HttpRequestMessage>(), ItExpr.IsAny<CancellationToken>())
                .ReturnsAsync(new HttpResponseMessage {
                    StatusCode = HttpStatusCode.OK,
                    Content = new StringContent(testContent)
                });
            var underTest = new SiteAnalyzer(new HttpClient(mockMessageHandler.Object));

            // Act
            var result = await underTest.GetContentSize("http://anyurl");

            // Assert
            Assert.Equal(testContent.Length, result);
        }
    }
}

If your looking to type up the message and then your bot will send it to the user, here is the code. It also has a role restriction on it :)

case 'dm':
  mentiondm = message.mentions.users.first();
  message.channel.bulkDelete(1);
  if (!message.member.roles.cache.some(role => role.name === "Owner")) return message.channel.send('Beep Boing: This command is way too powerful for you to use!');
  if (mentiondm == null) return message.reply('Beep Boing: No user to send message to!');
  mentionMessage = message.content.slice(3);
  mentiondm.send(mentionMessage);
  console.log('Message Sent!')
  break;

Edit 2:

Some time This Code Not worked proper

Same-origin policy

https://en.wikipedia.org/wiki/Same-origin_policy

https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1]. 

Ref : https://superuser.com/questions/773719/how-do-all-of-these-save-video-from-youtube-services-work/773998#773998

url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts              // DASH: contains video or audio stream

Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this

url  // direct HTTP link to a video
itag // code specifying the quality
s    // signature, security measure to counter downloading

Each URL will be encoded so you will need to decode them. Now the tricky part.

YouTube has at least 3 security levels for their videos

unsecured // as expected, you can download these with just the unencoded URL
s         // see below
RTMPE     // uses "rtmpe://" protocol, no known method for these

The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.

The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as

AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this

function mo(a) {
  a = a.split("");
  a = lo.rw(a, 1);
  a = lo.rw(a, 32);
  a = lo.IC(a, 1);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 44);
  return a.join("")
}

This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as

http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js

this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header

Access-Control-Allow-Origin: http://www.youtube.com

and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests

Access-Control-Allow-Origin: *

So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.

This is very simple you are trying to convert an integer to a list object !!! of course it will fail and it should ...

To demonstrate/prove this to you by using the example you provided ...just use type function for each case as below and the results will speak for itself !

>>> type(cow)
<class 'range'>
>>> 
>>> type(cow[0])
<class 'int'>
>>> 
>>> type(0)
<class 'int'>
>>> 
>>> >>> list(0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>> 

I use the following solution, it's quite simple and elegant, can be easily pasted into source, and works on Linux/Bash:

const std::string red("\033[0;31m");
const std::string green("\033[1;32m");
const std::string yellow("\033[1;33m");
const std::string cyan("\033[0;36m");
const std::string magenta("\033[0;35m");
const std::string reset("\033[0m");

std::cout << "Measured runtime: " << yellow << timer.count() << reset << std::endl;

Essentially two things you need to do are use a custom TrustStrategy that trusts all certs, and also use NoopHostnameVerifier() to disable hostname verification. Here is the code, with all the relevant imports:

import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

public RestTemplate getRestTemplate() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
    TrustStrategy acceptingTrustStrategy = new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
            return true;
        }
    };
    SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier());
    CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);
    RestTemplate restTemplate = new RestTemplate(requestFactory);
    return restTemplate;
}

I found a solution for the wiping the console in an Eclipse IDE. It uses the Robot class. Please see code below and caption for explanation:

   import java.awt.AWTException;
   import java.awt.Robot;
   import java.awt.event.KeyEvent;

   public void wipeConsole() throws AWTException{
        Robot robbie = new Robot();
        //shows the Console View
        robbie.keyPress(KeyEvent.VK_ALT);
        robbie.keyPress(KeyEvent.VK_SHIFT);
        robbie.keyPress(KeyEvent.VK_Q);
        robbie.keyRelease(KeyEvent.VK_ALT);
        robbie.keyPress(KeyEvent.VK_SHIFT);
        robbie.keyPress(KeyEvent.VK_Q);
        robbie.keyPress(KeyEvent.VK_C);
        robbie.keyRelease(KeyEvent.VK_C);

        //clears the console
        robbie.keyPress(KeyEvent.VK_SHIFT);
        robbie.keyPress(KeyEvent.VK_F10);
        robbie.keyRelease(KeyEvent.VK_SHIFT);
        robbie.keyRelease(KeyEvent.VK_F10);
        robbie.keyPress(KeyEvent.VK_R);
        robbie.keyRelease(KeyEvent.VK_R);
    }

Assuming you haven't changed the default hot key settings in Eclipse and import those java classes, this should work.

For Db2 for Linux, Unix and Windows (i.e. Db2 LUW) or for Db2 Warehouse use the SYSCAT.TABLES catalog view. E.g.

SELECT TABSCHEMA, TABNAME FROM SYSCAT.TABLES WHERE TABSCHEMA LIKE '%CUR%' AND TYPE = 'T'

Which is a SQL statement that will return all standard tables in all schema that contains the substring CUR. From a Db2 command line you could also use a CLP command e.g. db2 list tables for all | grep CUR to similar effect

This page describes the columns in SYSCAT.TABLES including the different values for the TYPE column.

A = Alias
G = Created temporary table
H = Hierarchy table
L = Detached table
N = Nickname
S = Materialized query table
T = Table (untyped)
U = Typed table
V = View (untyped)
W = Typed view

Other commonly used catalog views incude

SYSCAT.COLUMNS      Lists the columns in each table, view and nickname
SYSCAT.VIEWS        Full SQL text for view and materialized query tables
SYSCAT.KEYCOLUSE    Column that are in PK, FK or Uniuqe constraints

In Db2 LUW it is considered bad practice to use the SYSIBM catalog tables (which the SYSCAT catalog views select thier data from). They are less consistent as far as column names go, are not quite as easy to use, are not documented and are more likely to change between versions.

This page has a list of all the catalog views Road map to the catalog views

For Db2 for z/OS, use SYSIBM.TABLES which is described here. E.g.

SELECT CREATOR, NAME FROM SYSIBM.SYSTABLES WHERE OWNER LIKE '%CUR%' AND TYPE = 'T'

For Db2 for i (i.e. iSeries aka AS/400) use QSYS2.SYSTABLES which is described here

SELECT TABLE_OWNER, TABLE_NAME FROM QSYS2.SYSTABLES WHERE TABLE_SCHEMA LIKE '%CUR%' AND TABLE_TYPE = 'T'

For DB2 Server for VSE and VM use SYSTEM.SYSCATALOG which is described here DB2 Server for VSE and VM SQL Reference

SELECT CREATOR, TNAME FROM SYSTEM.SYSCATALOG WHERE TABLETYPE = 'R'

Mime type option is not best option for validating CSV file. I used this code this worked well in all browser

$type = explode(".",$_FILES['file']['name']);
if(strtolower(end($type)) == 'csv'){

}
else
{

}

A little slower, but readable I think:

>>> s, l, m
([5, 4, 3, 2, 1, 0], [0, 1, 3, 5], [0, 0, 0, 0])
>>> d = dict(zip(l, m))
>>> d  #dict is better then using two list i think
{0: 0, 1: 0, 3: 0, 5: 0}
>>> [d.get(i, j) for i, j in enumerate(s)]
[0, 0, 3, 0, 1, 0]

With python3, iterate on dic.keys() will raise the dictionary size error. You can use this alternative way:

Tested with python3, it works fine and the Error "dictionary changed size during iteration" is not raised:

my_dic = { 1:10, 2:20, 3:30 }
# Is important here to cast because ".keys()" method returns a dict_keys object.
key_list = list( my_dic.keys() )

# Iterate on the list:
for k in key_list:
    print(key_list)
    print(my_dic)
    del( my_dic[k] )


print( my_dic )
# {}

hashCode() method is not for providing a unique identifier for an object. It rather digests the object's state (i.e. values of member fields) to a single integer. This value is mostly used by some hash based data structures like maps and sets to effectively store and retrieve objects.

If you need an identifier for your objects, I recommend you to add your own method instead of overriding hashCode. For this purpose, you can create a base interface (or an abstract class) like below.

public interface IdentifiedObject<I> {
    I getId();
}

Example usage:

public class User implements IdentifiedObject<Integer> {
    private Integer studentId;

    public User(Integer studentId) {
        this.studentId = studentId;
    }

    @Override
    public Integer getId() {
        return studentId;
    }
}

Use the constructor that takes a File and a boolean

FileOutputStream(File file, boolean append) 

and set the boolean to true. That way, the data you write will be appended to the end of the file, rather than overwriting what was already there.

BeautifulSoup has a function named findNext from current element directed childern,so:

father.findNext('div',{'class':'class_value'}).findNext('div',{'id':'id_value'}).findAll('a') 

Above code can imitate the following xpath:

div[class=class_value]/div[id=id_value]

It is not that different from obj-c. First, you have to specify the protocol in your class declaration, like following:

class MyClass: NSUserNotificationCenterDelegate

The implementation will look like following:

// NSUserNotificationCenterDelegate implementation
func userNotificationCenter(center: NSUserNotificationCenter, didDeliverNotification notification: NSUserNotification) {
    //implementation
}

func userNotificationCenter(center: NSUserNotificationCenter, didActivateNotification notification: NSUserNotification) {
    //implementation
}

func userNotificationCenter(center: NSUserNotificationCenter, shouldPresentNotification notification: NSUserNotification) -> Bool {
    //implementation
    return true
}

Of course, you have to set the delegate. For example:

NSUserNotificationCenter.defaultUserNotificationCenter().delegate = self;

Java 8+

import java.nio.charset.StandardCharsets
import java.nio.file.{Files, Paths}

val path = Paths.get("file.txt")
new String(Files.readAllBytes(path), StandardCharsets.UTF_8)

Java 11+

import java.nio.charset.StandardCharsets
import java.nio.file.{Files, Path}

val path = Path.of("file.txt")
Files.readString(path, StandardCharsets.UTF_8)

These offer control over character encoding, and no resources to clean up. It's also faster than other patterns (e.g. getLines().mkString("\n")) due to more efficient allocation patterns.

I ran into this on a friend's HTML code and in his case, he was missing quotes.

For example:

<form action="formHandler.php" name="yourForm" id="theForm" method="post">    
<input type="text" name="fname" id="fname" style="width:90;font-size:10>     
<input type="submit" value="submit"/>
</form>

In this example, a missing quote on the input text fname will simply render the submit button un-usable and the form will not submit.

Of course, this is a bad example because I should be using CSS in the first place ;) but anyways, check all your single and double quotes to see that they are closing properly.

Also, if you have any tags like center, move them out of the form.

<form action="formHandler.php" name="yourForm" id="theForm" method="post">  
<center> <-- bad

As strange it may seems, it can have an impact.

You can cast the the json as follows:

Given your class:

export class Employee{
    firstname: string= '';
}

and the json:

let jsonObj = {
    "firstname": "Hesham"
};

You can cast it as follows:

let e: Employee = jsonObj as Employee;

And the output of console.log(e); is:

{ firstname: 'Hesham' }

Sorry for adding another answer to an old post but I usually get a scroll event very well by using this code (it works at least on 6.1)

element.addEventListener('scroll', function() {
    console.log(this.scrollTop);
});

// This is the magic, this gives me "live" scroll events
element.addEventListener('gesturechange', function() {});

And that works for me. Only thing it doesn't do is give a scroll event for the deceleration of the scroll (Once the deceleration is complete you get a final scroll event, do as you will with it.) but if you disable inertia with css by doing this

-webkit-overflow-scrolling: none;

You don't get inertia on your elements, for the body though you might have to do the classic

document.addEventListener('touchmove', function(e) {e.preventDefault();}, true);

This is responsive code and also open with different size in mobile view please check once.

.modal {
  text-align: center;
  padding: 0!important;
}

.modal:before {
  content: '';
  display: inline-block;
  height: 20%;

  margin-right: -4px;
}

.modal-dialog {
  display: inline-block;
  text-align: left;
  vertical-align: middle;
}

My problem and the solution

1. I have a 32 bit third party dll which I have installed in 2008 R2 machine which is 64 bit.

2. I have a wcf service created in .net 4.5 framework which calls the 32 bit third party dll for process. Now I have build property set to target 'any' cpu and deployed it to the 64 bit machine.

3. When Ii tried to invoke the wcf service got error "80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG"

4. Now Ii used ProcMon.exe to trace the com registry issue and identified that the process is looking for the registry entry at HKLM\CLSID and HKCR\CLSID where there is no entry.

5. Came to know that Microsoft will not register the 32 bit com components to the paths HKLM\CLSID, HKCR\CLSID in 64 bit machine rather it places the entry in HKLM\Wow6432Node\CLSID and HKCR\Wow6432Node\CLSID paths.

6. Now the conflict is 64 bit process trying to invoke 32 bit process in 64 bit machine which will look for the registry entry in HKLM\CLSID, HKCR\CLSID. The solution is we have to force the 64 bit process to look at the registry entry at HKLM\Wow6432Node\CLSID and HKCR\Wow6432Node\CLSID.

7. This can be achieved by configuring the wcf service project properties to target to 'X86' machine instead of 'Any'.

8. After deploying the 'X86' version to the 2008 R2 server got the issue "System.BadImageFormatException: Could not load file or assembly"

9. Solution to this badimageformatexception is setting the 'Enable32bitApplications' to 'True' in IIS Apppool properties for the right apppool.

It is an old post, but I came across this recently

Selecting a specific interval

As @aleroot already mentioned, by using

table.setRowSelectionInterval(index0, index1);

You can specify an interval, which should be selected.

Adding an interval to the existing selection

You can also keep the current selection, and simply add additional rows by using this here

table.getSelectionModel().addSelectionInterval(index0, index1);

This line of code additionally selects the specified interval. It doesn't matter if that interval already is selected, of parts of it are selected.

Use double quotation marks.

string foo = @"this ""word"" is escaped";

What you want to do is separate the content of the table from the header of the table. You want only the <th> elements to be scrolled. You can easily define this separation in HTML with the <tbody> and the <thead> elements.
Now the header and the body of the table are still connected to each other, they will still have the same width (and same scroll properties). Now to let them not 'work' as a table anymore you can set the display: block. This way <thead> and <tbody> are separated.

table tbody, table thead
{
    display: block;
}

Now you can set the scroll to the body of the table:

table tbody 
{
   overflow: auto;
   height: 100px;
}

And last, because the <thead> doesn't share the same width as the body anymore, you should set a static width to the header of the table:

th
{
    width: 72px;
}

You should also set a static width for <td>. This solves the issue of the unaligned columns.

td
{
    width: 72px;
}

<tr>
     <th>head1</th>
     <th>head2</th>
     <th>head3</th>
     <th>head4</th>
</tr>

I hope this is what you meant.

jsFiddle

Addendum

If you would like to have more control over the column widths, have them to vary in width between each other, and course keep the header and body columns aligned, you can use the following example:

    table th:nth-child(1), td:nth-child(1) { min-width: 50px;  max-width: 50px; }
    table th:nth-child(2), td:nth-child(2) { min-width: 100px; max-width: 100px; }
    table th:nth-child(3), td:nth-child(3) { min-width: 150px; max-width: 150px; }
    table th:nth-child(4), td:nth-child(4) { min-width: 200px; max-width: 200px; }

I thought .GetAwaiter().GetResult() was exactly the solution to this problem, no? eg:

string _Title;
public string Title
{
    get
    {
        if (_Title == null)
        {   
            _Title = getTitle().GetAwaiter().GetResult();
        }
        return _Title;
    }
    set
    {
        if (value != _Title)
        {
            _Title = value;
            RaisePropertyChanged("Title");
        }
    }
}

Solution of dmajkic help me at last:

For Windows users it may means: git client coudn’t find your keys. Check keys in c:\Users\UserName.ssh\ and! environment variable HOME=c:\Users\UserName\

The JavaDoc explains it very well:

With this option set to a non-zero timeout, a read() call on the InputStream associated with this Socket will block for only this amount of time. If the timeout expires, a java.net.SocketTimeoutException is raised, though the Socket is still valid. The option must be enabled prior to entering the blocking operation to have effect. The timeout must be > 0. A timeout of zero is interpreted as an infinite timeout.

SO_TIMEOUT is the timeout that a read() call will block. If the timeout is reached, a java.net.SocketTimeoutException will be thrown. If you want to block forever put this option to zero (the default value), then the read() call will block until at least 1 byte could be read.

Perform the following steps:

1. Start the Registry Editor by typing regedit in the Run window.
2. Select the following key in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\ODBC.
3. In the Security menu, click Permissions.
4. Grant Full Permission to the account which is being used for making connections.
5. Quit the Registry Editor.

1. Switch to Branch2

   git checkout Branch2
   

2. Apply the current (Branch2) changes on top of the Branch1 changes, staying in Branch2:

   git rebase Branch1
   

Which would leave you with the desired result in Branch2:

a -- b -- c                      <-- Master
           \
            d -- e               <-- Branch1
           \
            d -- e -- f' -- g'   <-- Branch2

You can delete Branch1.

I'd suggest try the change event? test to see if it has a value if it does then you can continue with your code. jQuery has

.bind("change", function(){ ... });

Or

.change(function(){ ... }); 

which are equivalents.

http://api.jquery.com/change/

for a unique selector change your name attribute to id and then jQuery("#imafile") or a general jQuery('input[type="file"]') for all the file inputs

Solution using Java 8 and Stream Api:

private static <K, V>  List<V> createListFromMapEntries (Map<K, V> map){
        return map.values().stream().collect(Collectors.toList());
    }

Usage:

  public static void main (String[] args)
    {
        Map<Integer, String> map = new HashMap<>();
        map.put(1, "one");
        map.put(2, "two");
        map.put(3, "three");

        List<String> result = createListFromMapEntries(map);
        result.forEach(System.out :: println);
    }

   canvas.addEventListener('click', function(event) {
      click++;
      if(click == 50) {
          this.removeEventListener('click',arguments.callee,false);
      }

Should do it.

Use the lag function:

SELECT value - lag(value) OVER (ORDER BY Id) FROM table

Sequences used for Ids can skip values, so Id-1 does not always work.

Here is another way of doing this by using es6 template literals dynamically at runtime.

const str = 'My name is ${name} and my age is ${age}.'_x000D_
const obj = {name:'Simon', age:'33'}_x000D_
_x000D_
_x000D_
const result = new Function('const {' + Object.keys(obj).join(',') + '} = this.obj;return `' + str + '`').call({obj})_x000D_
_x000D_
document.body.innerHTML = result

I'm currently using the CuTest unit test framework:

http://cutest.sourceforge.net/

It's ideal for embedded systems as it's very lightweight and simple. I had no problems getting it to work on the target platform as well as on the desktop. In addition to writing the unit tests, all that's required is:

• a header file included wherever you're calling the CuTest routines
• a single additional 'C' file to be compiled/linked into the image
• some simple code added to to main to set up and call the unit tests - I just have this in a special main() function that gets compiled if UNITTEST is defined during the build.

The system needs to support a heap and some stdio functionality (which not all embedded systems have). But the code is simple enough that you could probably work in alternatives to those requirements if your platform doesn't have them.

With some judicious use of extern "C"{} blocks it also supports testing C++ just fine.

IP can be any LAN or WAN IP address. But you'll want to set your firewall connection allow it.

Device connection with webserver pc can be by LAN or WAN (i.e by wifi, connectify, adhoc, cable, mypublic wifi etc)

You should follow these steps:

1. Go to the control panel

You should use parameters in your query to prevent attacks, like if someone entered '); drop table ArticlesTBL;--' as one of the values.

string query = "INSERT INTO ArticlesTBL (ArticleTitle, ArticleContent, ArticleType, ArticleImg, ArticleBrief,  ArticleDateTime, ArticleAuthor, ArticlePublished, ArticleHomeDisplay, ArticleViews)";
query += " VALUES (@ArticleTitle, @ArticleContent, @ArticleType, @ArticleImg, @ArticleBrief, @ArticleDateTime, @ArticleAuthor, @ArticlePublished, @ArticleHomeDisplay, @ArticleViews)";

SqlCommand myCommand = new SqlCommand(query, myConnection);
myCommand.Parameters.AddWithValue("@ArticleTitle", ArticleTitleTextBox.Text);
myCommand.Parameters.AddWithValue("@ArticleContent", ArticleContentTextBox.Text);
// ... other parameters
myCommand.ExecuteNonQuery();

Command to remove Cordova and ionic

• For Window system

  • npm uninstall -g ionic
  • npm uninstall -g cordova

• For Mac system

  • sudo npm uninstall -g ionic
  • sudo npm uninstall -g cordova

• For install cordova and ionic

  • npm install -g cordova
  • npm install -g ionic

Note:

• If you want to install in MAC System use before npm use sudo only.
• And plan to install specific version of ionic and cordova then use @(version no.).

eg.

sudo npm install -g [email protected]

sudo npm install -g [email protected]

You can comma-separate shadows:

box-shadow: inset 0 2px 0px #dcffa6, 0 2px 5px #000;

At a guess, you used Code::Blocks to create a Console Application project. Such a project does not link in the GDI stuff, because console applications are generally not intended to do graphics, and TextOut is a graphics function. If you want to use the features of the GDI, you should create a Win32 Gui Project, which will be set up to link in the GDI for you.

$value = ( array_key_exists($key, $array) && !empty($array[$key]) ) 
         ? $array[$key] 
         : 'non-existant or empty value key';

I am using XAMPP and came across the same error. I had done all those steps, added environmental variables path, copied the dll's every directory possible, to /php, /apache/bin, /system32, /syswow64, etc.. but still got this error.

Then after checking the apache error log, I noticed the issue with using brackets in path.

PHP: syntax error, unexpected '(' in C:\Program Files (other)\xampp\php\php.ini on line 707 0 server certificate does NOT include an ID which matches the server name

If you have installed the server in "Program Files (x86)" directory, the same error might occur due to the non-escaped brackets.

To fix this, open php.ini file and locate the line containing "include_path" and enclose the path with double quotes to fix this error.

include_path="C:\Program Files (other)\xampp\php\PEAR"

Try adding in webpack, it solved the similar issue in my project. Specially the "presets" part.

module: {
    loaders: [
        {
            test: /\.jsx?/,
            include: APP_DIR,
            loader: 'babel',
            query  :{
                presets:['react','es2015']
            }
        },

This is for create a text file

For i = 1 to 10
    createFile( i )
Next

Public Sub createFile(a)

    Dim fso,MyFile
    filePath = "C:\file_name" & a & ".txt"
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set MyFile = fso.CreateTextFile(filePath)
    MyFile.WriteLine("This is a separate file")
    MyFile.close

End Sub

And this for read a text file

Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
Set dict = CreateObject("Scripting.Dictionary")
Set file = fso.OpenTextFile ("test.txt", 1)
row = 0
Do Until file.AtEndOfStream
  line = file.Readline
  dict.Add row, line
  row = row + 1
Loop

file.Close

For Each line in dict.Items
  WScript.Echo line
  WScript.Sleep 1000
Next

:goto 21490 will take you to the 21490th byte in the buffer.

Recent I have met several times of stop abnormal. Although shutdown.sh provides some information, The situations are:

• result of the command ps -ef| grep java is Null.
• result of the command ps -ef| grep java is not null.

My opinion is just kill the process of Catalina and remove the pid file (In your situation is /opt/tomcat/work/catalina.pid.)

The result seems not so seriously to influence others.

select <column list> into <dest. table> from <source table>;

You could do this way.

SELECT windows_release, windows_service_pack_level, 
       windows_sku, os_language_version
into   new_table_name
FROM   sys.dm_os_windows_info OPTION (RECOMPILE);

This might not be the simplest answer as compared to using array_values().

Try this

$array = array( 0 => 'string1', 2 => 'string2', 4 => 'string3', 5 => 'string4');
$arrays =$array;
print_r($array);
$array=array();
$i=0;
    foreach($arrays as $k => $item)
    {
    $array[$i]=$item;
        unset($arrays[$k]);
        $i++;

    }

print_r($array);

mysql datetime -> GregorianCalendar

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = format.parse("2012-12-13 14:54:30"); // mysql datetime format
GregorianCalendar calendar = new GregorianCalendar();
calendar.setTime(date);
System.out.println(calendar.getTime());

GregorianCalendar -> mysql datetime

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String string = format.format(calendar.getTime());
System.out.println(string);

If that number represents milliseconds, use the Date's constructor :

var myDate = new Date(1238540400000);

ravgs = [sum(data[i:i+5])/5. for i in range(len(data)-4)]

This isn't the most efficient approach but it will give your answer and I'm unclear if your window is 5 points or 10. If its 10, replace each 5 with 10 and the 4 with 9.

Using an Array:

String[] fruits = new String[3]; // make a 3 element array
fruits[0]="apple";
fruits[1]="banana";
fruits[2]="orange";
System.out.println(fruits[1]); // output the second element

Using a List

ArrayList<String> fruits = new ArrayList<String>();
fruits.add("apple");
fruits.add("banana");
fruits.add("orange");
System.out.println(fruits.get(1));

I had today the same problem, but only when working with a stored procedure. This make the query behave like a multi query, so you need to "consume" other results available before make another query.

while($this->mysql->more_results()){
    $this->mysql->next_result();
    $this->mysql->use_result();
}

It is proper to use reduce as in Antonio Laguna's answer.

Apologies for the brevity...

The accepted answer was at the time it was offered thought to be correct. As it turns out, there is no substitute for callable(), which is back in Python 3.2: Specifically, callable() checks the tp_call field of the object being tested. There is no plain Python equivalent. Most of the suggested tests are correct most of the time:

>>> class Spam(object):
...     def __call__(self):
...         return 'OK'
>>> can_o_spam = Spam()


>>> can_o_spam()
'OK'
>>> callable(can_o_spam)
True
>>> hasattr(can_o_spam, '__call__')
True
>>> import collections
>>> isinstance(can_o_spam, collections.Callable)
True

We can throw a monkey-wrench into this by removing the __call__ from the class. And just to keep things extra exciting, add a fake __call__ to the instance!

>>> del Spam.__call__
>>> can_o_spam.__call__ = lambda *args: 'OK?'

Notice this really isn't callable:

>>> can_o_spam()
Traceback (most recent call last):
  ...
TypeError: 'Spam' object is not callable

callable() returns the correct result:

>>> callable(can_o_spam)
False

But hasattr is wrong:

>>> hasattr(can_o_spam, '__call__')
True

can_o_spam does have that attribute after all; it's just not used when calling the instance.

Even more subtle, isinstance() also gets this wrong:

>>> isinstance(can_o_spam, collections.Callable)
True

Because we used this check earlier and later deleted the method, abc.ABCMeta caches the result. Arguably this is a bug in abc.ABCMeta. That said, there's really no possible way it could produce a more accurate result than the result than by using callable() itself, since the typeobject->tp_call slot method is not accessible in any other way.

Just use callable()

The easiest way to add a text to a JFrame:

JFrame window = new JFrame("JFrame with text"); 
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setLayout(new BorderLayout());
window.add(new JLabel("Hello World"), BorderLayout.CENTER);
window.pack();
window.setVisible(true);
window.setLocationRelativeTo(null);

Nto sure which RDBMS you are using, but if it is SQL Server you could look at rather using a CASE statement

Evaluates a list of conditions and returns one of multiple possible result expressions.

The CASE expression has two formats:

The simple CASE expression compares an expression to a set of simple expressions to determine the result.

The searched CASE expression evaluates a set of Boolean expressions to determine the result.

Both formats support an optional ELSE argument.

• Ruby require is more like "include" in other languages (such as C). It tells Ruby that you want to bring in the contents of another file. Similar mechanisms in other languages are:

  • using <namespace> directive in C#.
  • import <package> in Java.

• Ruby include is an object-oriented inheritance mechanism used for mixins.

There is a good explanation here:

[The] simple answer is that require and include are essentially unrelated.

"require" is similar to the C include, which may cause newbie confusion. (One notable difference is that locals inside the required file "evaporate" when the require is done.)

The Ruby include is nothing like the C include. The include statement "mixes in" a module into a class. It's a limited form of multiple inheritance. An included module literally bestows an "is-a" relationship on the thing including it.

Emphasis added.

There's no built-in JavaScript function to do this, but you can write your own fairly easily:

function pad(n) {
    return (n < 10) ? ("0" + n) : n;
}

EDIT:

Meanwhile there is a native JS function that does that. See String#padStart

console.log(String(5).padStart(2, '0'));

list has a count method:

>>> [True,True,False].count(True)
2

This is actually more efficient than sum, as well as being more explicit about the intent, so there's no reason to use sum:

In [1]: import random

In [2]: x = [random.choice([True, False]) for i in range(100)]

In [3]: %timeit x.count(True)
970 ns ± 41.1 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [4]: %timeit sum(x)
1.72 µs ± 161 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

I like Alex FTPS Client which is written by a Microsoft MVP name Alex Pilotti. It's a C# library you can use in Console apps, Windows Forms, PowerShell, ASP.NET (in any .NET language). If you have a multithreaded app you will have to configure the library to run syncronously, but overall a good client that will most likely get you what you need.

before for loop :

$data = array();

then in your loop:

$data[] = array($catagory => $question);

Employee emp1 = new Employee() { ID = 1, Name = "Narendra1", Salary = 11111, Experience = 3, Age = 30 };Employee emp2 = new Employee() { ID = 2, Name = "Narendra2", Salary = 21111, Experience = 10, Age = 38 };
Employee emp3 = new Employee() { ID = 3, Name = "Narendra3", Salary = 31111, Experience = 4, Age = 33 };
Employee emp4 = new Employee() { ID = 3, Name = "Narendra4", Salary = 41111, Experience = 7, Age = 33 };

List<Employee> lstEmployee = new List<Employee>();

lstEmployee.Add(emp1);
lstEmployee.Add(emp2);
lstEmployee.Add(emp3);
lstEmployee.Add(emp4);

var eemmppss=lstEmployee.Select(cc=>new {cc.ID,cc.Age}).Distinct();

Yes. It calls the render() method every time we call setState only except when "shouldComponentUpdate" returns false.

For resolving a single parameter (I guess what's most commonly needed), this is the simplest I found:

build.buildVariableResolver.resolve("myparameter")

in your Groovy System script build step.

Probably the cleanest way to do it in Java 8:

private int[] randomIntArray() {
   Random rand = new Random();
   return IntStream.range(0, 23).map(i -> rand.nextInt()).toArray();
}

When using the highest voted answer above, first example, i was getting individual characters for string lengths greater than 1. Below is my solution for that problem.

var stringObject = ["", "some string yay", "", "", "Other string yay"];
stringObject = stringObject.filter(function(n){ return n.length > 0});

Instead of not returning if undefined, we return if length is greater than 0. Hope that helps somebody out there.

Returns

["some string yay", "Other string yay"]

Simple Css work for me

.modal-dialog { 
max-width : 100% ;
}

 $(document).ready(function(){
    $("#select_all").click(function(){
      var checked_status = this.checked;
      $("input[name='select[]']").each(function(){
        this.checked = checked_status;
      });
    });
  });

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

SELECT "Gc_Staff_Number",
       "Start_Date",
       (SELECT "End_Date"
        FROM   "Employment_History"
        WHERE  "Current_Flag" != 'Y'
               AND ROWNUM = 1
               AND "Employee_Number" = "Employment_History"."Employee_Number"
        ORDER  BY "End_Date" ASC)
FROM   "Employment_History"
WHERE  "Current_Flag" = 'Y'

FYI, the ROWNUM = 1 gets evaluated before the ORDER BY in this case, so that inner query will sort a grand total of (at most) one record.

If you really are looking for the earliest end_date for a given employee (where current_flag <> 'Y') is this what you're looking for?

SELECT "Gc_Staff_Number",
       "Start_Date",
       eh.end_date
  FROM "Employment_History" eh
       LEFT OUTER JOIN -- in case the current record is the only record...
       (SELECT "Employee_Number"
             , MIN("End_Date") as end_date
          FROM "Employment_History"
         WHERE "Current_Flag" != 'Y'
         GROUP BY "Employee_Number" 
       ) emp_end_date
          ON eh."Employee_Number" = emp_end_date."Employee_Number"
 WHERE eh."Current_Flag" = 'Y'

You need a new version of notepad++. Looks like old versions don't support |.

Note: egrep "CAT|TOWN" will search for lines containing CATOWN. (CAT)|(TOWN) is the proper or extension (matching 1,3,4). Strangely you wrote and which is btw (CAT.*TOWN)|(TOWN.*CAT)

Consider using System.Collections.Specialized.OrderedDictionary, though it is not generic, or implement your own (example).

OrderedDictionary does not support IndexOf, but it's easy to implement:

public static class OrderedDictionaryExtensions
{
    public static int IndexOf(this OrderedDictionary dictionary, object value)
    {
        for(int i = 0; i < dictionary.Count; ++i)
        {
            if(dictionary[i] == value) return i;
        }
        return -1;
    }
}

I was having this issue and fixed it by going to: C:\Dev-Cpp\libexec\gcc\mingw32\3.4.2 , then deleting collect2.exe

Again if using IOS on Xamarin there is a new component called BTProgressHUD in the component store

curl is a command in linux (and a library in php). Curl typically makes an HTTP request.

What you really want to do is make an HTTP (or XHR) request from javascript.

Using this vocab you'll find a bunch of examples, for starters: Sending authorization headers with jquery and ajax

Essentially you will want to call $.ajax with a few options for the header, etc.

$.ajax({
        url: 'https://api.wit.ai/message?v=20140826&q=',
        beforeSend: function(xhr) {
             xhr.setRequestHeader("Authorization", "Bearer 6QXNMEMFHNY4FJ5ELNFMP5KRW52WFXN5")
        }, success: function(data){
            alert(data);
            //process the JSON data etc
        }
})

As explained above not just the db datatype it will also affect the view that will be generated if you are scaffolding. string will generate a text_field text will generate a text_area

Best Optimized code for multi line files having no newline('\n') character at EOF.

/**

jquery will execute both handler since it allows multiple event handlers. I have created sample code. You can try it

demo

**difference between text()&& html() && val()...?
#Html code..
<select id="d">
<option>Hello</option>
<option>Welcome</option>
</select>
# jquery code..
$(document).ready(function(){
   $("#d").html();
   $("#d").text();
   $("#d").val();

});

Use the vector constructor that takes two iterators, note that pointers are valid iterators, and use the implicit conversion from arrays to pointers:

int x[3] = {1, 2, 3};
std::vector<int> v(x, x + sizeof x / sizeof x[0]);
test(v);

or

test(std::vector<int>(x, x + sizeof x / sizeof x[0]));

where sizeof x / sizeof x[0] is obviously 3 in this context; it's the generic way of getting the number of elements in an array. Note that x + sizeof x / sizeof x[0] points one element beyond the last element.

For GitHub users without Git installed:

If you want to restore it from GitHub website, you can use their API to get a list of repo-related events:

First

• find those SHAs (commit hashes):

  curl -i https://api.github.com/repos/PublicUser/PublicRepo/events

  ... or for private repos:

  curl -su YourUserName https://api.github.com/repos/YourUserName/YourProject/events

  (will be prompted for GitHub password)

  • (If the repo rquires two-factor auth, see the comments on this answer below.)

Next

• go to GitHub and create a new temporary branch which will be deleted for ever (Chrome is preferable).

   •  Go to branches and delete that one.

   •  On the same page, without reloading, open DevTools, Network panel. Now prepare...

   •  Click restore. You will notice a new "line". Right-click on it and select "Copy as cURL" and save this text in some editor.

   •  Append to the end of the copied line of code, this one: -H "Cookie=".

You should now get something like:

    curl 'https://github.com/UserName/ProjectName/branches?branch=BranchSHA&name=BranchName' -H 'Cookie:' -H 'Origin: https://github.com' -H 'Accept-Encoding: gzip, deflate, br' -H 'Accept-Language: en-US' -H 'User-Agent: User-Agent' -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' -H 'Accept: */*' -H 'Referer: https://github.com/UserName/ProjectName/branches' -H 'X-Requested-With: XMLHttpRequest' -H 'Connection: keep-alive' --data 'utf8=%E2%9C%93&authenticity_token=token' --compressed

Final step

• replace "BranchSHA" with your SHA-hash and BranchName with desired name (BTW, it is great hack to rename branch from web). If you were not too slow, you need to make this request anyhow. For example, just copy-paste to a terminal.

P.S.

I realize this may not be the "simplest solution" or the "right" solution, but it is offered in case someone finds it useful.

Because in 2nd case you adding same reference twice and HashSet have check against this in HashMap.put() on which HashSet is based:

        if (e.hash == hash && ((k = e.key) == key || key.equals(k))) {
            V oldValue = e.value;
            e.value = value;
            e.recordAccess(this);
            return oldValue;
        }

As you can see, equals will be called only if hash of key being added equals to the key already present in set and references of these two are different.

It seems to work when I replace the

Runtime.getRuntime().exec("rmiregistry 2020");

by

LocateRegistry.createRegistry(2020);

anyone an idea why? What's the difference?

/^[a-zA-Z]*$/

Change the * to + if you don't want to allow empty matches.

References:

Character classes ([...]), Anchors (^ and $), Repetition (+, *)

The / are just delimiters, it denotes the start and the end of the regex. One use of this is now you can use modifiers on it.

Encapsulation is important in any OO language, popularity has nothing to do with it. In dynamically typed languages, like PHP, it is especially useful because there is little ways to ensure a property is of a specific type without using setters.

In PHP, this works:

class Foo {
   public $bar; // should be an integer
}
$foo = new Foo;
$foo->bar = "string";

In Java, it doesn't:

class Foo {
   public int bar;
}
Foo myFoo = new Foo();
myFoo.bar = "string"; // error

Using magic methods (__get and __set) also works, but only when accessing a property that has lower visibility than the current scope can access. It can easily give you headaches when trying to debug, if it is not used properly.

As per the other answers, add the following to someFile.js

module.exports.someFunction = function () {
  console.log('hi');
};

You can then add the following to package.json

"scripts": {
   "myScript": "node -e 'require(\"./someFile\").someFunction()'"
}

From the terminal, you can then call

npm run myScript

I find this a much easier way to remember the commands and use them

. given a path, how can we recursively create all the folders necessary to create the file .. for that path

Creates all directories and subdirectories as specified by path.

Directory.CreateDirectory(path);

then you may create a file.

To solve the problem I use ${string_prompt} variable. It shows a input dialog when application runs. I can set the date/time manually at that dialog.

1. Move cursor at the end of file path.

2. Click variables and select string_prompt

3. Select Apply and Run

I hope this help. Haven't tried it out yet, will post again once I tested it.

While jkp's solution works, the newer way of doing things (and the way the documentation recommends) is to use the subprocess module. For simple commands its equivalent, but it offers more options if you want to do something complicated.

Example for your case:

import subprocess
subprocess.Popen(["rm","-r","some.file"])

This will run rm -r some.file in the background. Note that calling .communicate() on the object returned from Popen will block until it completes, so don't do that if you want it to run in the background:

import subprocess
ls_output=subprocess.Popen(["sleep", "30"])
ls_output.communicate()  # Will block for 30 seconds

See the documentation here.

Also, a point of clarification: "Background" as you use it here is purely a shell concept; technically, what you mean is that you want to spawn a process without blocking while you wait for it to complete. However, I've used "background" here to refer to shell-background-like behavior.

I had the same problem. I changed the order of the scripts in the head part, and it worked for me. Every script the plugin needs - needs to stay close.

For example:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript" src="http://cloud.github.com/downloads/malsup/cycle/jquery.cycle.all.latest.js"></script>
<script type="text/javascript"> 
$(document).ready(function() {
    $('#slider').cycle({
            fx: 'fade' 
        });
    });
</script>

Linking the scrollers worked, but in the way it's written it creates a loop which makes scrolling slow in most browsers if you click on the part of the lighter scrollbar and hold it (not when dragging the scroller).

I fixed it with a flag:

$(function() {
    x = 1;
    $(".wrapper1").scroll(function() {
        if (x == 1) {
            x = 0;
            $(".wrapper2")
                .scrollLeft($(".wrapper1").scrollLeft());
        } else {
            x = 1;
        }
    });


    $(".wrapper2").scroll(function() {
        if (x == 1) {
            x = 0;
            $(".wrapper1")
                .scrollLeft($(".wrapper2").scrollLeft());
        } else {
            x = 1;
        }
    });
});

You should check that fractional part of the number is 0. Use

x==Math.ceil(x)

or

x==Math.round(x)

or something like that

function valid(id)
    {
        var textVal=document.getElementById(id).value;
        if (!textVal.match("Tryit") 
        {
            alert("Field says Tryit");
            return false;
        } 
        else 
        {
            return true;
        }
     }

Use this for expressing things

Definitely EditPad Lite !

It's extremely fast not just while opening files, but also functions like "Replace All", trimming of leading/trailing whitespaces or converting content to lowercase are very fast.

And it is also very similar to Notepad++ ;)

Here's a great reason to use objectForKey: wherever possible instead of valueForKey: - valueForKey: with an unknown key will throw NSUnknownKeyException saying "this class is not key value coding-compliant for the key ".

vector<string> getseq(char * db_file)

And if you want to print it on main() you should do it in a loop.

int main() {
     vector<string> str_vec = getseq(argv[1]);
     for(vector<string>::iterator it = str_vec.begin(); it != str_vec.end(); it++) {
         cout << *it << endl;
     }
}

I think you want

listb.pop()[0]

The expression listb.pop is a valid python expression which results in a reference to the pop method, but doesn't actually call that method. You need to add the open and close parentheses to call the method.

A litle bit complete answer is here with all ready for use:

    $sql = "SELECT `username` FROM `users` WHERE `id` = :id";
    $q = $dbh->prepare($sql);
    $q->execute(array(':id' => "4"));
    $done= $q->fetch();

 echo $done[0];

Here $dbh is PDO db connecter, and based on id from table users we've get the username using fetch();

I hope this help someone, Enjoy!

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

I met with the same problem when I did MSI install of MySQL and there were no my-medium.ini files too when I tried the above steps. Only installing the ZIP file of MySQL helped me. So, I suggest you to uninstall the MSI installed folder and reinstall using the ZIP file.

Middleware is a general term for software that serves to "glue together" separate, often complex and already existing, programs. Some software components that are frequently connected with middleware include enterprise applications and Web services.

The best thing would be to set your own error and exception handlers which will do something usefull like logging it in a file or emailing critical ones. http://www.php.net/set_error_handler

In this code:

class Cat:
    def __init__(self, name):
        self.name = name
    def info(self):
        print 'I am a cat and I am called', self.name

Here __init__ acts as a constructor for the class and when an object is instantiated, this function is called. self represents the instantiating object.

c = Cat('Kitty')
c.info()

The result of the above statements will be as follows:

I am a cat and I am called Kitty

You can obfuscate it, but there's no way of protecting it completely.

example obfuscator: https://obfuscator.io

The HTTP/CGI way to do this would be for your program to return an HTTP status code of 204 (No Content).

Following this resource page, if the length of x is varying, we can use:

', '.join(['%.2f']*len(x))

to create a place holder for each element from the list x. Here is the example:

x = [1/3.0, 1/6.0, 0.678]
s = ("elements in the list are ["+', '.join(['%.2f']*len(x))+"]") % tuple(x)
print s
>>> elements in the list are [0.33, 0.17, 0.68]

Do you really want to style the <div>? Or do you want to style the <input type="button">? You should use the correct selector if you want the latter:

input[type=button] {
    color:#08233e;
    font:2.4em Futura, ‘Century Gothic’, AppleGothic, sans-serif;
    font-size:70%;
    /* ... other rules ... */
    cursor:pointer;
}

input[type=button]:hover {
    background-color:rgba(255,204,0,0.8);
}

StarUML does just that and it is free. Unfortunately it hasn't been updated for a while. There were a couple of offshoot projects (as the project admins wouldn't allow it to be taken over) but they too have died a death.

We can count from many ways for the occurrence of substring:-

public class Test1 {
public static void main(String args[]) {
    String st = "abcdsfgh yfhf hghj gjgjhbn hgkhmn abc hadslfahsd abcioh abc  a ";
    count(st, 0, "a".length());

}

public static void count(String trim, int i, int length) {
    if (trim.contains("a")) {
        trim = trim.substring(trim.indexOf("a") + length);
        count(trim, i + 1, length);
    } else {
        System.out.println(i);
    }
}

public static void countMethod2() {
    int index = 0, count = 0;
    String inputString = "mynameiskhanMYlaptopnameishclMYsirnameisjasaiwalmyfrontnameisvishal".toLowerCase();
    String subString = "my".toLowerCase();

    while (index != -1) {
        index = inputString.indexOf(subString, index);
        if (index != -1) {
            count++;
            index += subString.length();
        }
    }
    System.out.print(count);
}}

I had this problem, the solution was to look at the commit graph (using gitk) and see that I had the following:

*   commit I want to cherry-pick (x)
|\  
| * branch I want to cherry-pick to (y)
* | 
|/  
* common parent (x)

I understand now that I want to do

git cherry-pick -m 2 mycommitsha

This is because -m 1 would merge based on the common parent where as -m 2 merges based on branch y, that is the one I want to cherry-pick to.

Just to kick a long-dead horse, because I've had to implement an optional argument in the middle of two or more required arguments. Use the arguments array and use the last one as the required non-optional argument.

my_function() {
  var options = arguments[argument.length - 1];
  var content = arguments.length > 1 ? arguments[0] : null;
}

Unless somefunction is a very bad coded legacy function, you shouldn't need what you're asking.

Use multiple except clause to handle in different ways different exceptions:

try:
    someFunction()
except ValueError:
    # do something
except ZeroDivision:
    # do something else

The main point is that you shouldn't catch generic exception, but only the ones that you need to. I'm sure that you don't want to shadow unexpected errors or bugs.

I would also recommend to use Notepad++ with json-view extension. You get the extension here: https://sourceforge.net/projects/nppjsonviewer/ Install and restart Notepad++. Then open json-file in Notepad and go to "extensions -> Json-Viewer - > Format JSON. Then you habe the hierarchical view of json.

You can also use one of the online-viewers (http://jsonviewer.stack.hu/ , https://jsoneditoronline.org/) which look nice, but I wouldn't recommend this if your data are sensitive in terms of privacy.

You probably want to check the length of the string first and do something like this:

if (!myStr.empty())
{
    char lastChar = *myStr.rbegin();
}

For casting varchar fields/values to number format can be little hack used:

SELECT (`PROD_CODE` * 1) AS `PROD_CODE` FROM PRODUCT`

in modern browsers you can do the following...

button.addEventListener( 'click', () => {
    alert( 'only once!' );
}, { once: true } );

If libncurses is not installed then install it and try again. sudo apt-get install libncurses5:i386

or sudo apt-get install libncurses5 for 64 bit binaries

Also install the collection of libraries by using this command sudo apt-get install ia32-libs

SQL Server uses the TCP port 1433. This is probably blocked either by the VPN tunnel or by a firewall on the server.

I created a service that will do this for you.

Pass in a standard $http object, and add some extra parameters.

1) A "type" parameter. Specifying the type of file you're retrieving. Defaults to: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
2) A "fileName" parameter. This is required, and should include the extension.

Example:

httpDownloader({
  method : 'POST',
  url : '--- enter the url that returns a file here ---',
  data : ifYouHaveDataEnterItHere,
  type : 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', // this is the default
  fileName : 'YourFileName.xlsx'
}).then(res => {}).catch(e => {});

That's all you need. The file will be downloaded to the user's device without a popup.

Here's the git repo: https://github.com/stephengardner/ngHttpDownloader

Think of it as a letter. Sometimes you get a letter, say asking you to fill in a form then return the form in a pre-addressed envelope which is in the original envelope that was housing the form.

Once you have finished filling the form in, you put it in the provided return envelop and send it back.

The callbackUrl is like that return envelope. You are basically saying I am sending you this data. Once you are done with it, I am on this callbackUrl waiting for your response. So the API will process the data you have sent then look at the callback to send you the response.

This is useful because sometimes you may take ages to process some data and it makes no sense to have the caller wait for a response. For example, say your API allows users to send documents to it and virus scan them. Then you send a report after. The scan could take maybe 3minutes. The user cannot be waiting for 3minutes. So you acknowledge that you got the document and let the caller get on with other business while you do the scan then use the callbackUrl when done to tell them the result of the scan.

Maximum number of connections are impacted by certain limits on both client & server sides, albeit a little differently.

On the client side: Increase the ephermal port range, and decrease the tcp_fin_timeout

To find out the default values:

sysctl net.ipv4.ip_local_port_range
sysctl net.ipv4.tcp_fin_timeout

The ephermal port range defines the maximum number of outbound sockets a host can create from a particular I.P. address. The fin_timeout defines the minimum time these sockets will stay in TIME_WAIT state (unusable after being used once). Usual system defaults are:

• net.ipv4.ip_local_port_range = 32768 61000
• net.ipv4.tcp_fin_timeout = 60

This basically means your system cannot consistently guarantee more than (61000 - 32768) / 60 = 470 sockets per second. If you are not happy with that, you could begin with increasing the port_range. Setting the range to 15000 61000 is pretty common these days. You could further increase the availability by decreasing the fin_timeout. Suppose you do both, you should see over 1500 outbound connections per second, more readily.

To change the values:

sysctl net.ipv4.ip_local_port_range="15000 61000"
sysctl net.ipv4.tcp_fin_timeout=30

The above should not be interpreted as the factors impacting system capability for making outbound connections per second. But rather these factors affect system's ability to handle concurrent connections in a sustainable manner for large periods of "activity."

Default Sysctl values on a typical Linux box for tcp_tw_recycle & tcp_tw_reuse would be

net.ipv4.tcp_tw_recycle=0
net.ipv4.tcp_tw_reuse=0

These do not allow a connection from a "used" socket (in wait state) and force the sockets to last the complete time_wait cycle. I recommend setting:

sysctl net.ipv4.tcp_tw_recycle=1
sysctl net.ipv4.tcp_tw_reuse=1 

This allows fast cycling of sockets in time_wait state and re-using them. But before you do this change make sure that this does not conflict with the protocols that you would use for the application that needs these sockets. Make sure to read post "Coping with the TCP TIME-WAIT" from Vincent Bernat to understand the implications. The net.ipv4.tcp_tw_recycle option is quite problematic for public-facing servers as it won’t handle connections from two different computers behind the same NAT device, which is a problem hard to detect and waiting to bite you. Note that net.ipv4.tcp_tw_recycle has been removed from Linux 4.12.

On the Server Side: The net.core.somaxconn value has an important role. It limits the maximum number of requests queued to a listen socket. If you are sure of your server application's capability, bump it up from default 128 to something like 128 to 1024. Now you can take advantage of this increase by modifying the listen backlog variable in your application's listen call, to an equal or higher integer.

sysctl net.core.somaxconn=1024

txqueuelen parameter of your ethernet cards also have a role to play. Default values are 1000, so bump them up to 5000 or even more if your system can handle it.

ifconfig eth0 txqueuelen 5000
echo "/sbin/ifconfig eth0 txqueuelen 5000" >> /etc/rc.local

Similarly bump up the values for net.core.netdev_max_backlog and net.ipv4.tcp_max_syn_backlog. Their default values are 1000 and 1024 respectively.

sysctl net.core.netdev_max_backlog=2000
sysctl net.ipv4.tcp_max_syn_backlog=2048

Now remember to start both your client and server side applications by increasing the FD ulimts, in the shell.

Besides the above one more popular technique used by programmers is to reduce the number of tcp write calls. My own preference is to use a buffer wherein I push the data I wish to send to the client, and then at appropriate points I write out the buffered data into the actual socket. This technique allows me to use large data packets, reduce fragmentation, reduces my CPU utilization both in the user land and at kernel-level.

$sql = "SELECT * FROM table_name ORDER BY ID DESC LIMIT 1";
$records = mysql_query($sql);

you can change LIMIT 1 to LIMIT any number you want

This will show you the last INSERTED row first.

List<String> listA = new ArrayList<String>();

    listA.add("A");
    listA.add("B");

List<String> listB = new ArrayList<String>();

    listB.add("B");
    listB.add("C");

Set<String> newSet = new HashSet<String>(listA);

    newSet.addAll(listB);
List<String> newList = new ArrayList<String>(newSet);

System.out.println("New List :"+newList);

is giving you New List :[A, B, C]

I know this has been answered already, but I am here to offer a word of warning. We recently received a database from a client that has a cyclical foreign key reference. The SQL Server script generator refuses to generate the data for databases with cyclical references.

No, destructors are called automatically in the reverse order of construction. (Base classes last). Do not call base class destructors.

Here's an easy extension to do this:

https://gist.github.com/stevenojo/0cb8afcba721838b8dcb115b846727c3

extension Dictionary {
    func jsonString() -> NSString? {
        let jsonData = try? JSONSerialization.data(withJSONObject: self, options: [])
        guard jsonData != nil else {return nil}
        let jsonString = String(data: jsonData!, encoding: .utf8)
        guard jsonString != nil else {return nil}
        return jsonString! as NSString
    }

}

The most easiest way I came up with to send the push notification to all the devices is to subscribe them to a topic "all" and then send notification to this topic. Copy this in your main activity

FirebaseMessaging.getInstance().subscribeToTopic("all");

Now send the request as

{
   "to":"/topics/all",
   "data":
   {
      "title":"Your title",
      "message":"Your message"
      "image-url":"your_image_url"
   }
}

This might be inefficient or non-standard way, but as I mentioned above it's the easiest. Please do post if you have any better way to send a push notification to all the devices.

_{You can follow this tutorial if you're new to sending push notifications using Firebase Cloud Messaging Tutorial - Push Notifications using FCM}

To send a message to a combination of topics, specify a condition, which is a boolean expression that specifies the target topics. For example, the following condition will send messages to devices that are subscribed to TopicA and either TopicB or TopicC:

{
   "data":
   {
      "title": "Your title",
      "message": "Your message"
      "image-url": "your_image_url"
   },
   "condition": "'TopicA' in topics && ('TopicB' in topics || 'TopicC' in topics)"
}

Read more about conditions and topics here on FCM documentation

Modify to suit your specifics, or make more generic as needed:

Private Sub CopyItOver()
  Set NewBook = Workbooks.Add
  Workbooks("Whatever.xlsx").Worksheets("output").Range("A1:K10").Copy
  NewBook.Worksheets("Sheet1").Range("A1").PasteSpecial (xlPasteValues)
  NewBook.SaveAs FileName:=NewBook.Worksheets("Sheet1").Range("E3").Value
End Sub

Go to System Properties > Advanced > Enviroment Variables and look under System variables

First, create/set your JAVA_HOME variable

Even though Eclipse doesn't consult the JAVA_HOME variable, it's still a good idea to set it. See How do I run Eclipse? for more information.

If you have not created and/or do not see JAVA_HOME under the list of System variables, do the following:

1. Click New... at the very bottom
2. For Variable name, type JAVA_HOME exactly
3. For Variable value, this could be different depending on what bits your computer and java are.
   • If both your computer and java are 64-bit, type C:\Program Files\Java\jdk1.8.0_60
   • If both your computer and java are 32-bit, type C:\Program Files\Java\jdk1.8.0_60
   • If your computer is 64-bit, but your java is 32-bit, type C:\Program Files (x86)\Java\jdk1.8.0_60

If you have created and/or do see JAVA_HOME, do the following:

1. Click on the row under System variables that you see JAVA_HOME in
2. Click Edit... at the very bottom
3. For Variable value, change it to what was stated in #3 above based on java's and your computer's bits. To repeat:
   • If both your computer and java are 64-bit, change it to C:\Program Files\Java\jdk1.8.0_60
   • If both your computer and java are 32-bit, change it to C:\Program Files\Java\jdk1.8.0_60
   • If your computer is 64-bit, but your java is 32-bit, change it to C:\Program Files (x86)\Java\jdk1.8.0_60

Next, add to your PATH variable

1. Click on the row under System variables with PATH in it
2. Click Edit... at the very bottom
3. If you have a newer version of windows:
   • Click New
   • Type in C:\Program Files (x86)\Java\jdk1.8.0_60 OR C:\Program Files\Java\jdk1.8.0_60 depending on the bits of your computer and java (see above ^).
   • Press Enter and Click New again.
   • Type in C:\Program Files (x86)\Java\jdk1.8.0_60\jre OR C:\Program Files\Java\jdk1.8.0_60\jre depending on the bits of your computer and java (see above again ^).
   • Press Enter and press OK on all of the related windows
4. If you have an older version of windows
   • In the Variable value textbox (or something similar) drag the cursor all the way to the very end
   • Add a semicolon (;) if there isn't one already
   • C:\Program Files (x86)\Java\jdk1.8.0_60 OR C:\Program Files\Java\jdk1.8.0_60
   • Add another semicolon (;)
   • C:\Program Files (x86)\Java\jdk1.8.0_60\jre OR C:\Program Files\Java\jdk1.8.0_60\jre

Changing eclipse.ini

1. Find your eclipse.ini file and copy-paste it in the same directory (should be named eclipse(1).ini)
2. Rename eclipse.ini to eclipse.ini.old just in case something goes wrong
3. Rename eclipse(1).ini to eclipse.ini

4. Open your newly-renamed eclipse.ini and replace all of it with this:

   -startup
   plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
   --launcher.library
   plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
   -product
   org.eclipse.epp.package.java.product
   --launcher.defaultAction
   openFile
   --launcher.XXMaxPermSize
   256M
   -showsplash
   org.eclipse.platform
   --launcher.XXMaxPermSize
   256m
   --launcher.defaultAction
   openFile
   -vm
   C:\Program Files\Java\jdk1.8.0_60\bin\javaw.exe
   -vmargs
   -Dosgi.requiredJavaVersion=1.5
   -Xms40m
   -Xmx1024m
   

XXMaxPermSize may be deprecated, so it might not work. If eclipse still does not launch, do the following:

1. Delete the newer eclipse.ini
2. Rename eclipse.ini.old to eclipse.ini
3. Open command prompt
4. type in eclipse -vm C:\Program Files (x86)\Java\jdk1.8.0_60\bin\javaw.exe

If the problem remains

Try updating your eclipse and java to the latest version. 8u60 (1.8.0_60) is not the latest version of java. Sometimes, the latest version of java doesn't work with older versions of eclipse and vice versa. Otherwise, leave a comment if you're still having problems. You could also try a fresh reinstallation of Java.

The normal layout for a maven multi module project is:

parent
+-- pom.xml
+-- module
    +-- pom.xml

Check that you use this layout.

Additionally:

1. the relativePath looks strange. Instead of '..'

   <relativePath>..</relativePath>
   

   try '../' instead:

   <relativePath>../</relativePath>
   

   You can also remove relativePath if you use the standard layout. This is what I always do, and on the command line I can build as well the parent (and all modules) or only a single module.

2. The module path may be wrong. In the parent you define the module as:

   <module>junitcategorizer.cutdetection</module>
   

   You must specify the name of the folder of the child module, not an artifact identifier. If junitcategorizer.cutdetection is not the name of the folder than change it accordingly.

Hope that helps..

EDIT have a look at the other post, I answered there.

You can also use,

output <- as.matrix(as.data.frame(z))

The memory usage is very similar to

output <- matrix(unlist(z), ncol = 10, byrow = TRUE)

Which can be verified, with mem_changed() from library(pryr).
