HttpContext localContext = new BasicHttpContext();
localContext.setAttribute(HttpClientContext.COOKIE_STORE, cookieStore);
response = client.execute(httppost, localContext);

doesn't work in 4.5 version without

cookie.setDomain(".domain.com");
cookie.setAttribute(ClientCookie.DOMAIN_ATTR, "true");

Open a command prompt:

 Version:  java -version
 Location: where java (in Windows)
           which java (in Unix, Linux, and Mac)

To set Java home in Windows:

Right click on My computer → Properties → Advanced system settings → Environment Variable → System Variable → New. Give the name as JAVA_HOME and the value as (e.g.) c:\programfiles\jdk

Select Path and click Edit, and keep it in the beginning as: %JAVA_HOME%\bin;...remaining settings goes here

You can call the method like pump.getPumps(). By adding @classmethod decorator on the method. A class method receives the class as the implicit first argument, just like an instance method receives the instance.

class Pump:

def __init__(self):
    print ("init") # never prints

@classmethod
def getPumps(cls):
            # Open database connection
            # some stuff here that never gets executed because of error

So, simply call Pump.getPumps() .

In java, it is termed as static method.

This solution is not good every time. But i have only two columns and I want second column to take all the remaining space. This worked for me

 <tr>
    <td class="text-nowrap">A</td>
    <td class="w-100">B</td>
 </tr>

Use setDataAndType on the Intent

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(newVideoPath), "video/mp4");
startActivity(intent);

Use "video/mp4" as MIME or use "video/*" if you don't know the type.

Theres a few ways you can do this. You can either add a background to the canvas you are currently working on, which if the canvas isn't going to be redrawn every loop is fine. Otherwise you can make a second canvas underneath your main canvas and draw the background to it. The final way is to just use a standard <img> element placed under the canvas. To draw a background onto the canvas element you can do something like the following:

Live Demo

var canvas = document.getElementById("canvas"),
    ctx = canvas.getContext("2d");

canvas.width = 903;
canvas.height = 657;


var background = new Image();
background.src = "http://www.samskirrow.com/background.png";

// Make sure the image is loaded first otherwise nothing will draw.
background.onload = function(){
    ctx.drawImage(background,0,0);   
}

// Draw whatever else over top of it on the canvas.

I did use following solution to this:

findAllByStartDateLessThanEqualAndEndDateGreaterThanEqual(OffsetDateTime endDate, OffsetDateTime startDate);

A problem I was running into was that I was using the webpack-simple install for VueJS which didn't seem to include an Environment variable config folder. So I wasn't able to edit the env.test,development, and production.js config files. Creating them didn't help either.

Other answers weren't detailed enough for me, so I just "fiddled" with webpack.config.js. And the following worked just fine.

So to get Environment Variables to work, the webpack.config.js should have the following at the bottom:

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true,
      compress: {
        warnings: false
      }
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: true
    })
  ])
}

Based on the above, in production, you would be able to get the NODE_ENV variable

mounted() {
  console.log(process.env.NODE_ENV)
}

Now there may be better ways to do this, but if you want to use Environment Variables in Development you would do something like the following:

if (process.env.NODE_ENV === 'development') {

  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"development"'
      }
    })
  ]);

} 

Now if you want to add other variables with would be as simple as:

if (process.env.NODE_ENV === 'development') {

  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"development"',
        ENDPOINT: '"http://localhost:3000"',
        FOO: "'BAR'"
      }
    })
  ]);
}

I should also note that you seem to need the "''" double quotes for some reason.

So, in Development, I can now access these Environment Variables:

mounted() {
  console.log(process.env.ENDPOINT)
  console.log(process.env.FOO)
}

Here is the whole webpack.config.js just for some context:

var path = require('path')
var webpack = require('webpack')

        options: {

        }

}

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({

if (process.env.NODE_ENV === 'development') {

  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({

        ENDPOINT: '"http://localhost:3000"',
        FOO: "'BAR'"
      }
    })
  ]);

Follow these:

1. open your xampp control panel then click its "config"

2. choose the "Apache (httpd.conf)" and find this code below and change it into this one:

   # Change this to Listen on specific IP addresses as shown below to 
   # prevent Apache from glomming onto all bound IP addresses.
   #
   #Listen 0.0.0.0:80
   #Listen [::]:80
   Listen 80
   #
   # Dynamic Shared Object (DSO) Support
   

3. save it (ctrl + s)

4. after that, go back to xampp control panel and click again its config

5. choose "Apache (httpd-ssl.conf)" find this code below and change it again:

   # Note: Configurations that use IPv6 but not IPv4-mapped addresses need two
   #       Listen directives: "Listen [::]:443" and "Listen 0.0.0.0:443"
   #
   #Listen 0.0.0.0:443
   #Listen [::]:443
   Listen 443
   

6. save it (ctrl + s)

7. then, click the "config" (note: above the netstat) and click the "service and port settings" then save both of it.

8. finally, go to the "control panel" -> "Programs & Features" -> "Turn Windows On or Off".

9. Uncheck your "Internet Information Services" then click ok.

Just wait for it and your computer/laptop will be automatically restart and try to open again your xampp control panel then start your Apache.

Have you tried sc.exe?

C:\> for /f "tokens=2*" %a in ('sc query audiosrv ^| findstr STATE') do echo %b
4  RUNNING

C:\> for /f "tokens=2*" %a in ('sc query sharedaccess ^| findstr STATE') do echo %b

Note that inside a batch file you'd double each percent sign.

Use NetworkCredential

Yep, just add these two lines to your code.

var credentials = new System.Net.NetworkCredential("username", "password");

client.Credentials = credentials;

I tried using:

Range(cells(1, 1), cells(lastRow, lastColumn)).Select 

where lastRow and lastColumn are integers, but received run-time error 1004. I'm using an older VB (6.5).

What did work was to use the following:

Range(Chr(64 + firstColumn) & firstRow & ":" & Chr(64 + lastColumn) & firstColumn).Select.  

HTML Code:-

<input type="text" name="txt1" id="txt1" onkeypress="return AddKeyPress(event);" />      

<input type="button" id="btnclick">

Java Script Code

function AddKeyPress(e) { 
        // look for window.event in case event isn't passed in
        e = e || window.event;
        if (e.keyCode == 13) {
            document.getElementById('btnEmail').click();
            return false;
        }
        return true;
    }

Your Form do not have Default Submit Button

In your example it's just part of the method name. In Ruby you can also use exclamation points in method names!

Another example of question marks in Ruby would be the ternary operator.

customerName == "Fred" ? "Hello Fred" : "Who are you?"

  }
  else if (response.error) {

Addressing Steven's comment to Sam Dufel's answer

Thanks, sounds like that's the way to go. But I just realized that I only want the optional whitespace characters if they follow a newline. So for example, "c\n ats" or "ca\n ts" should match. But wouldn't want "c ats" to match if there is no newline. Any ideas on how that might be done?

This should do the trick:

/c(?:\n\s*)?a(?:\n\s*)?t(?:\n\s*)?s/

See this page for all the different variations of 'cats' that this matches.

You can also solve this using conditionals, but they are not supported in the javascript flavor of regex.

The best tool for doing layouts using grid, IMHO, is graph paper and a pencil. I know you're asking for some type of program, but it really does work. I've been doing Tk programming for a couple of decades so layout comes quite easily for me, yet I still break out graph paper when I have a complex GUI.

Another thing to think about is this: The real power of Tkinter geometry managers comes from using them together*. If you set out to use only grid, or only pack, you're doing it wrong. Instead, design your GUI on paper first, then look for patterns that are best solved by one or the other. Pack is the right choice for certain types of layouts, and grid is the right choice for others. For a very small set of problems, place is the right choice. Don't limit your thinking to using only one of the geometry managers.

* The only caveat to using both geometry managers is that you should only use one per container (a container can be any widget, but typically it will be a frame).

You only need <script></script> Tag that's it. <script type="text/javascript"></script> is not a valid HTML tag, so for best SEO practice use <script></script>

The reason that the performance of instanceof and getClass() == ... is different is that they are doing different things.

• instanceof tests whether the object reference on the left-hand side (LHS) is an instance of the type on the right-hand side (RHS) or some subtype.

• getClass() == ... tests whether the types are identical.

So the recommendation is to ignore the performance issue and use the alternative that gives you the answer that you need.

Is using the instanceOf operator bad practice ?

Not necessarily. Overuse of either instanceOf or getClass() may be "design smell". If you are not careful, you end up with a design where the addition of new subclasses results in a significant amount of code reworking. In most situations, the preferred approach is to use polymorphism.

However, there are cases where these are NOT "design smell". For example, in equals(Object) you need to test the actual type of the argument, and return false if it doesn't match. This is best done using getClass().

^{Terms like "best practice", "bad practice", "design smell", "antipattern" and so on should be used sparingly and treated with suspicion. They encourage black-or-white thinking. It is better to make your judgements in context, rather than based purely on dogma; e.g. something that someone said is "best practice". I recommend that everyone read No Best Practices if they haven't already done so.}

HEAD is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.

master is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).

origin is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.

To give the code that nstehr's answer refers to (from its source):

def timeparse(t, format):
    """Parse a time string that might contain fractions of a second.

    Fractional seconds are supported using a fragile, miserable hack.
    Given a time string like '02:03:04.234234' and a format string of
    '%H:%M:%S', time.strptime() will raise a ValueError with this
    message: 'unconverted data remains: .234234'.  If %S is in the
    format string and the ValueError matches as above, a datetime
    object will be created from the part that matches and the
    microseconds in the time string.
    """
    try:
        return datetime.datetime(*time.strptime(t, format)[0:6]).time()
    except ValueError, msg:
        if "%S" in format:
            msg = str(msg)
            mat = re.match(r"unconverted data remains:"
                           " \.([0-9]{1,6})$", msg)
            if mat is not None:
                # fractional seconds are present - this is the style
                # used by datetime's isoformat() method
                frac = "." + mat.group(1)
                t = t[:-len(frac)]
                t = datetime.datetime(*time.strptime(t, format)[0:6])
                microsecond = int(float(frac)*1e6)
                return t.replace(microsecond=microsecond)
            else:
                mat = re.match(r"unconverted data remains:"
                               " \,([0-9]{3,3})$", msg)
                if mat is not None:
                    # fractional seconds are present - this is the style
                    # used by the logging module
                    frac = "." + mat.group(1)
                    t = t[:-len(frac)]
                    t = datetime.datetime(*time.strptime(t, format)[0:6])
                    microsecond = int(float(frac)*1e6)
                    return t.replace(microsecond=microsecond)

        raise

For List:

All SwiftUI's Lists are backed by a UITableViewin iOS. so you need to change the background color of the tableView. But since Color and UIColor values are slightly different, you can get rid of the UIColor.

struct ContentView : View {
    init(){
        UITableView.appearance().backgroundColor = .clear
    }
    
    var body: some View {
        List {
            Section(header: Text("First Section")) {
                Text("First Cell")
            }
            Section(header: Text("Second Section")) {
                Text("First Cell")
            }
        }
        .background(Color.yellow)
    }
}

Now you can use Any background (including all Colors) you want

Also First look at this result:

As you can see, you can set the color of each element in the View hierarchy like this:

struct ContentView: View {
    
    init(){
        UINavigationBar.appearance().backgroundColor = .green 
        //For other NavigationBar changes, look here:(https://stackoverflow.com/a/57509555/5623035)
    }

    var body: some View {
        ZStack {
            Color.yellow
            NavigationView {
                ZStack {
                    Color.blue
                    Text("Some text")
                }
            }.background(Color.red)
        }
    }
}

And the first one is window:

window.backgroundColor = .magenta

The very common issue is we can not remove the background color of SwiftUI's HostingViewController (yet), so we can't see some of the views like navigationView through the views hierarchy. You should wait for the API or try to fake those views (not recommended).

I first used the JavaScript code, it worked amazingly until a website did not click.

So I've found this solution:

First, import ActionChains for Python & active it:

from selenium.webdriver.common.action_chains import ActionChains
actions = ActionChains(driver)

To click on a specific point in your sessions use this:

actions.move_by_offset(X coordinates, Y coordinates).click().perform()

NOTE: The code above will only work if the mouse has not been touched, to reset the mouse coordinates use this:

actions.move_to_element_with_offset(driver.find_element_by_tag_name('body'), 0,0))

In Full:

actions.move_to_element_with_offset(driver.find_element_by_tag_name('body'), 0,0)
actions.move_by_offset(X coordinates, Y coordinates).click().perform()

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

Download MSBuild with the link from @Nicodemeus answer was OK, yet the installation was broken until I've added these keys into a register:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\MSBuild\ToolsVersions\12.0]
"VCTargetsPath11"="$([MSBuild]::ValueOrDefault('$(VCTargetsPath11)','$(MSBuildExtensionsPath32)\\Microsoft.Cpp\\v4.0\\V110\\'))"
"VCTargetsPath"="$([MSBuild]::ValueOrDefault('$(VCTargetsPath)','$(MSBuildExtensionsPath32)\\Microsoft.Cpp\\v4.0\\V110\\'))" 

Use the id of the element to do the same.

document.getElementById(id).style.visibility = 'hidden';

If you're in control of the string, you could also use a 'Raw' string type:

>>> string = r"abcd\n"
>>> print(string)
abcd\n

You haven't stated where you're looking for the element. If it's within the scope of a controller, it is possible, despite the chorus you'll hear about it not being the 'Angular Way'. The chorus is right, but sometimes, in the real world, it's unavoidable. (If you disagree, get in touch—I have a challenge for you.)

If you pass $element into a controller, like you would $scope, you can use its find() function. Note that, in the jQueryLite included in Angular, find() will only locate tags by name, not attribute. However, if you include the full-blown jQuery in your project, all the functionality of find() can be used, including finding by attribute.

So, for this HTML:

<div ng-controller='MyCtrl'>
    <div>
        <div name='foo' class='myElementClass'>this one</div>
    </div>
</div>

This AngularJS code should work:

angular.module('MyClient').controller('MyCtrl', [
    '$scope',
    '$element',
    '$log',
    function ($scope, $element, $log) {

        // Find the element by its class attribute, within your controller's scope
        var myElements = $element.find('.myElementClass');

        // myElements is now an array of jQuery DOM elements

        if (myElements.length == 0) {
            // Not found. Are you sure you've included the full jQuery?
        } else {
            // There should only be one, and it will be element 0
            $log.debug(myElements[0].name); // "foo"
        }

    }
]);

If you're working in scala, a way to do this and use Future's is to create a RequestExecutor, then use the IndicesStatsRequestBuilder and the administrative client to submit your request.

import org.elasticsearch.action.{ ActionRequestBuilder, ActionListener, ActionResponse }
import scala.concurrent.{ Future, Promise, blocking }

/** Convenice wrapper for creating RequestExecutors */
object RequestExecutor {
    def apply[T <: ActionResponse](): RequestExecutor[T] = {
        new RequestExecutor[T]
    }
}

/** Wrapper to convert an ActionResponse into a scala Future
 *
 *  @see http://chris-zen.github.io/software/2015/05/10/elasticsearch-with-scala-and-akka.html
 */
class RequestExecutor[T <: ActionResponse] extends ActionListener[T] {
    private val promise = Promise[T]()

    def onResponse(response: T) {
        promise.success(response)
    }

    def onFailure(e: Throwable) {
        promise.failure(e)
    }

    def execute[RB <: ActionRequestBuilder[_, T, _, _]](request: RB): Future[T] = {
        blocking {
            request.execute(this)
            promise.future
        }
    }
}

The executor is lifted from this blog post which is definitely a good read if you're trying to query ES programmatically and not through curl. One you have this you can create a list of all indexes pretty easily like so:

def totalCountsByIndexName(): Future[List[(String, Long)]] = {
    import scala.collection.JavaConverters._
    val statsRequestBuider = new IndicesStatsRequestBuilder(client.admin().indices())
    val futureStatResponse = RequestExecutor[IndicesStatsResponse].execute(statsRequestBuider)
    futureStatResponse.map { indicesStatsResponse =>
        indicesStatsResponse.getIndices().asScala.map {
            case (k, indexStats) => {
                val indexName = indexStats.getIndex()
                val totalCount = indexStats.getTotal().getDocs().getCount()
                    (indexName, totalCount)
                }
        }.toList
    }
}

client is an instance of Client which can be a node or a transport client, whichever suits your needs. You'll also need to have an implicit ExecutionContext in scope for this request. If you try to compile this code without it then you'll get a warning from the scala compiler on how to get that if you don't have one imported already.

I needed the document count, but if you really only need the names of the indices you can pull them from the keys of the map instead of from the IndexStats:

indicesStatsResponse.getIndices().keySet()

This question shows up when you're searching for how to do this even if you're trying to do this programmatically, so I hope this helps anyone looking to do this in scala/java. Otherwise, curl users can just do as the top answer says and use

curl http://localhost:9200/_aliases

You could use the setTimeout() function:

// Your delay in milliseconds
var delay = 1000; 
setTimeout(function(){ window.location = URL; }, delay);

1. Checking for __iter__ works on sequence types, but it would fail on e.g. strings in Python 2. I would like to know the right answer too, until then, here is one possibility (which would work on strings, too):

   from __future__ import print_function
   
   try:
       some_object_iterator = iter(some_object)
   except TypeError as te:
       print(some_object, 'is not iterable')
   

   The iter built-in checks for the __iter__ method or in the case of strings the __getitem__ method.

2. Another general pythonic approach is to assume an iterable, then fail gracefully if it does not work on the given object. The Python glossary:

   Pythonic programming style that determines an object's type by inspection of its method or attribute signature rather than by explicit relationship to some type object ("If it looks like a duck and quacks like a duck, it must be a duck.") By emphasizing interfaces rather than specific types, well-designed code improves its flexibility by allowing polymorphic substitution. Duck-typing avoids tests using type() or isinstance(). Instead, it typically employs the EAFP (Easier to Ask Forgiveness than Permission) style of programming.

   ...

   try:
      _ = (e for e in my_object)
   except TypeError:
      print my_object, 'is not iterable'
   

3. The collections module provides some abstract base classes, which allow to ask classes or instances if they provide particular functionality, for example:

   from collections.abc import Iterable
   
   if isinstance(e, Iterable):
       # e is iterable
   

   However, this does not check for classes that are iterable through __getitem__.

UsedRange work fine with "virgins" cells, but if your cells are filled in the past, then UsedRange will deliver to you the old value.

For example:

"Think in a Excel sheet that have cells A1 to A5 filled with text". In this scenario, UsedRange must be implemented as:

Long SheetRows;
SheetRows = ActiveSheet.UsedRange.Rows.Count;

A watch to SheetRows variable must display a value of 5 after the execution of this couple of lines.

Q1: But, what happen if the value of A5 is deleted?

A1: The value of SheetRows would be 5

Q2: Why this?

A2: Because MSDN define UsedRange property as:

Gets a Microsoft.Office.Interop.Excel.Range object that represents all the cells that have contained a value at any time.

So, the question is: Exist some/any workaround for this behavior?

I think in 2 alternatives:

1. Avoid deleting the content of the cell, preferring deletion of the whole row (right click in the row number, then "delete row".
2. Use CurrentRegion instead of UsedRange property as follow:

Long SheetRows;
SheetRows = ActiveSheet.Range("A1").CurrentRegion.Rows.Count;

You need to use Integer.parseInt(String)

private void jTextField2MouseClicked(java.awt.event.MouseEvent evt) {
        if(evt.getSource()==jTextField2){
            int jml = Integer.parseInt(jTextField3.getText());
            jTextField1.setText(numberToWord(jml));

        }
    }

Your select count and select max should be from your table variable instead of the actual table

DECLARE @i int
DECLARE @PractitionerId int
DECLARE @numrows int
DECLARE @Practitioner TABLE (
    idx smallint Primary Key IDENTITY(1,1)
    , PractitionerId int
)

INSERT @Practitioner
SELECT distinct PractitionerId FROM Practitioner

SET @i = 1
SET @numrows = (SELECT COUNT(*) FROM @Practitioner)
IF @numrows > 0
    WHILE (@i <= (SELECT MAX(idx) FROM @Practitioner))
    BEGIN

        SET @PractitionerId = (SELECT PractitionerId FROM @Practitioner WHERE idx = @i)

        --Do something with Id here
        PRINT @PractitionerId

        SET @i = @i + 1
    END

date under Mac OSX is slightly different.

For yesterday

date -v-1d +%F

For Last week

date -v-1w +%F

range() returns a list, xrange() returns an xrange object.

xrange() is a bit faster, and a bit more memory efficient. But the gain is not very large.

The extra memory used by a list is of course not just wasted, lists have more functionality (slice, repeat, insert, ...). Exact differences can be found in the documentation. There is no bonehard rule, use what is needed.

Python 3.0 is still in development, but IIRC range() will very similar to xrange() of 2.X and list(range()) can be used to generate lists.

I always prefer let to an instance variable for a couple of reasons:

• Instance variables spring into existence when referenced. This means that if you fat finger the spelling of the instance variable, a new one will be created and initialized to nil, which can lead to subtle bugs and false positives. Since let creates a method, you'll get a NameError when you misspell it, which I find preferable. It makes it easier to refactor specs, too.
• A before(:each) hook will run before each example, even if the example doesn't use any of the instance variables defined in the hook. This isn't usually a big deal, but if the setup of the instance variable takes a long time, then you're wasting cycles. For the method defined by let, the initialization code only runs if the example calls it.
• You can refactor from a local variable in an example directly into a let without changing the referencing syntax in the example. If you refactor to an instance variable, you have to change how you reference the object in the example (e.g. add an @).
• This is a bit subjective, but as Mike Lewis pointed out, I think it makes the spec easier to read. I like the organization of defining all my dependent objects with let and keeping my it block nice and short.

A related link can be found here: http://www.betterspecs.org/#let

Guess I'm a bit late to the party, and although I agree that creating a seperate key for development (localhost) and product it is possible to do both in only 1 key.

When you use Application restrictions -> http referers -> Website restricitions you can enter wildcard urls.

However using a wildcard like .localhost/ or .localhost:{port}. (when already having .yourwebsite.com/* ) don't seem to work.

Just putting a single * does work but this basicly gives you an unlimited key which is not what you want either.

When you include the full path withhout using the wildcard * it also works, so in my case putting:

http://localhost{port}/
http://localhost:{port}/something-else/here

Makes the Google maps work both local as on www.yourwebsite.com using the same API key.

Anyway when having 2 seperate keys is also an option I would advise to do that.

I note that the o/p did not ask for a region-independent solution. My solution is for the UK though.

This is the simplest possible solution, a 1-line solution, for use in a Batch file:

FOR /F "tokens=1-3 delims=/" %%A IN ("%date%") DO (SET today=%%C-%%B-%%A)
echo %today%

Optimum buffer size is related to a number of things: file system block size, CPU cache size and cache latency.

Most file systems are configured to use block sizes of 4096 or 8192. In theory, if you configure your buffer size so you are reading a few bytes more than the disk block, the operations with the file system can be extremely inefficient (i.e. if you configured your buffer to read 4100 bytes at a time, each read would require 2 block reads by the file system). If the blocks are already in cache, then you wind up paying the price of RAM -> L3/L2 cache latency. If you are unlucky and the blocks are not in cache yet, the you pay the price of the disk->RAM latency as well.

This is why you see most buffers sized as a power of 2, and generally larger than (or equal to) the disk block size. This means that one of your stream reads could result in multiple disk block reads - but those reads will always use a full block - no wasted reads.

Now, this is offset quite a bit in a typical streaming scenario because the block that is read from disk is going to still be in memory when you hit the next read (we are doing sequential reads here, after all) - so you wind up paying the RAM -> L3/L2 cache latency price on the next read, but not the disk->RAM latency. In terms of order of magnitude, disk->RAM latency is so slow that it pretty much swamps any other latency you might be dealing with.

So, I suspect that if you ran a test with different cache sizes (haven't done this myself), you will probably find a big impact of cache size up to the size of the file system block. Above that, I suspect that things would level out pretty quickly.

There are a ton of conditions and exceptions here - the complexities of the system are actually quite staggering (just getting a handle on L3 -> L2 cache transfers is mind bogglingly complex, and it changes with every CPU type).

This leads to the 'real world' answer: If your app is like 99% out there, set the cache size to 8192 and move on (even better, choose encapsulation over performance and use BufferedInputStream to hide the details). If you are in the 1% of apps that are highly dependent on disk throughput, craft your implementation so you can swap out different disk interaction strategies, and provide the knobs and dials to allow your users to test and optimize (or come up with some self optimizing system).

Both answers were good so I moved them in to a directive so that it is reusable and a second scope variable doesn't have to be defined.

Here is the fiddle if you want to see it implemented

Below is the directive:

var uniqueItems = function (data, key) {
    var result = [];
    for (var i = 0; i < data.length; i++) {
        var value = data[i][key];
        if (result.indexOf(value) == -1) {
            result.push(value);
        }
    }
    return result;
};

myApp.filter('groupBy',
            function () {
                return function (collection, key) {
                    if (collection === null) return;
                    return uniqueItems(collection, key);
        };
    });

Then it can be used as follows:

<div ng-repeat="team in players|groupBy:'team'">
    <b>{{team}}</b>
    <li ng-repeat="player in players | filter: {team: team}">{{player.name}}</li>        
</div>

Using moment.js is as easy as:

var years = moment().diff('1981-01-01', 'years');
var days = moment().diff('1981-01-01', 'days');

For additional reference, you can read moment.js official documentation.

Another simple alternative:

for name_of_the_group, group in grouped_dataframe:
   print (name_of_the_group)
   print (group)

Compiled expression is best way! (for performance to repeatedly create instance in runtime).

static readonly Func<X> YCreator = Expression.Lambda<Func<X>>(
   Expression.New(typeof(Y).GetConstructor(Type.EmptyTypes))

AFAIK, there is no a interactive option for output to file, there is a previous SO question related with this: Printing mongodb shell output to File

However, you can log all the shell session if you invoked the shell with tee command:

$ mongo | tee file.txt
MongoDB shell version: 2.4.2
connecting to: test
> printjson({this: 'is a test'})
{ "this" : "is a test" }
> printjson({this: 'is another test'})
{ "this" : "is another test" }
> exit
bye

Then you'll get a file with this content:

MongoDB shell version: 2.4.2
connecting to: test
> printjson({this: 'is a test'})
{ "this" : "is a test" }
> printjson({this: 'is another test'})
{ "this" : "is another test" }
> exit
bye

To remove all the commands and keep only the json output, you can use a command similar to:

tail -n +3 file.txt | egrep -v "^>|^bye" > output.json

Then you'll get:

{ "this" : "is a test" }
{ "this" : "is another test" }

Join the table with itself and give it two different aliases (A and B in the following example). This allows to compare different rows of the same table.

SELECT DISTINCT A.Id
FROM
    Address A
    INNER JOIN Address B
        ON A.Id = B.Id AND A.[Adress Code] < B.[Adress Code]
WHERE
    A.Address <> B.Address

The "less than" comparison < ensures that you get 2 different addresses and you don't get the same 2 address codes twice. Using "not equal" <> instead, would yield the codes as (1, 2) and (2, 1); each one of them for the A alias and the B alias in turn.

The join clause is responsible for the pairing of the rows where as the where-clause tests additional conditions.

The query above works with any address codes. If you want to compare addresses with specific address codes, you can change the query to

SELECT A.Id
FROM
    Address A
    INNER JOIN Address B
        ON A.Id = B.Id
WHERE                     
    A.[Adress Code] = 1 AND
    B.[Adress Code] = 2 AND
    A.Address <> B.Address

I imagine that this might be useful to find customers having a billing address (Adress Code = 1 as an example) differing from the delivery address (Adress Code = 2) .

Use the global flag:

var name = name.replace(/[^a-zA-Z ]/g, "");
                                    ^

If you don't want to remove numbers, add it to the class:

var name = name.replace(/[^a-zA-Z0-9 ]/g, "");

There are two different ways of importing components in react and the recommended way is component way

1. Library way(not recommended)
2. Component way(recommended)

PFB detail explanation

Library way of importing

import { Button } from 'react-bootstrap';
import { FlatButton } from 'material-ui';

This is nice and handy but it does not only bundles Button and FlatButton (and their dependencies) but the whole libraries.

Component way of importing

One way to alleviate it is to try to only import or require what is needed, lets say the component way. Using the same example:

import Button from 'react-bootstrap/lib/Button';
import FlatButton from 'material-ui/lib/flat-button';

This will only bundle Button, FlatButton and their respective dependencies. But not the whole library. So I would try to get rid of all your library imports and use the component way instead.

If you are not using lot of components then it should reduce considerably the size of your bundled file.

In my eyes the best way to read from stdin in bash is the following one, which also lets you work on the lines before the input ends:

while read LINE; do
    echo $LINE
done < /dev/stdin

Only first part of Justin's answer is correct. Using "%.3g" will not work for all cases as .3 is not the precision, but total number of digits. Try it for numbers like 1000.123 and it breaks.

So, I would use what Justin is suggesting:

>>> ('%.4f' % 12340.123456).rstrip('0').rstrip('.')
'12340.1235'
>>> ('%.4f' % -400).rstrip('0').rstrip('.')
'-400'
>>> ('%.4f' % 0).rstrip('0').rstrip('.')
'0'
>>> ('%.4f' % .1).rstrip('0').rstrip('.')
'0.1'

You will also get this error if you have a generic declaration for both your class and your method. For example the code shown below gives this compile error.

public class Foo <T> {

    T var;

    public <T> void doSomething(Class <T> cls) throws InstantiationException, IllegalAccessException {
        this.var = cls.newInstance();
    }

}

This code does compile (note T removed from method declaration):

public class Foo <T> {

    T var;

    public void doSomething(Class <T> cls) throws InstantiationException, IllegalAccessException {
        this.var = cls.newInstance();
    }

}

Also, change this:

    SelBranchVal = SelBranchVal + "," + InvForm.SelBranch[x].value;

to

    SelBranchVal = SelBranchVal + InvForm.SelBranch[x].value+ "," ;

The reason is that for the first time the variable SelBranchVal will be empty

            headers: {'Content-Type': 'application/json'},
            body: JSON.stringify(data)
          }).then(function(response) {
            return response.blob();
          }).then(function(blob) {
            download (blob);
          })
        }
      });

An additional cause of this can be ES2015 arrow functions. They cannot be used as constructors.

const f = () => {};
new f(); // This throws "f is not a constructor"

You have to convert the "DateTime" to a "Date". Then you can easier select just one for the given date no matter the time for that date.

It is most likely a mismatch between the model class name and the table name as mentioned by 'adrift'. Make these the same or use the example below for when you want to keep the model class name different from the table name (that I did for OAuthMembership). Note that the model class name is OAuthMembership whereas the table name is webpages_OAuthMembership.

Either provide a table attribute to the Model:

[Table("webpages_OAuthMembership")]
public class OAuthMembership

OR provide the mapping by overriding DBContext OnModelCreating:

class webpages_OAuthMembershipEntities : DbContext
{
    protected override void OnModelCreating( DbModelBuilder modelBuilder )
    {
        var config = modelBuilder.Entity<OAuthMembership>();
        config.ToTable( "webpages_OAuthMembership" );            
    }
    public DbSet<OAuthMembership> OAuthMemberships { get; set; }        
}

For me, the issue was that I mistakenly placed test cases in an internal class

[TestClass]
internal class TestLib {
}

That was causing test cases not being identified.

Find the file "config.inc.php" under your phpMyAdmin directory and edit the following lines:

$cfg['Servers'][$i]['auth_type'] = 'config'; // config, http, cookie

$cfg['Servers'][$i]['user'] = 'root'; // MySQL user

$cfg['Servers'][$i]['password'] = 'TYPE_YOUR_PASSWORD_HERE'; // MySQL password

Note that the password used in the 'password' field must be the same for the MySQL root password. Also, you should check if root login is allowed in this line:

$cfg['Servers'][$i]['AllowRoot']     = TRUE;        // true = allow root login

This way you have your root password set.

Markdown doesn't have a defined syntax to underline text.

I guess this is because underlined text is hard to read, and that it's usually used for hyperlinks.

After this thread didn't work out for me for my specific need (scrolling inside a particular element, in my case a textarea) I found this out in the great beyond, which could prove helpful to someone else reading this discussion:

Since I already had a cached version of my jQuery object (the myPanel in the code below is the jQuery object), the code I added to my event handler was simply this:

myPanel.scrollTop(myPanel[0].scrollHeight - myPanel.height());

(thanks Ben)

Ofri's answer gives you everything you asked for. But.. if you don't want to remember the command you can add this to your ~/.bashrc (or equivalent):

csview()
{
local file="$1"
sed "s/,/\t/g" "$file" | less -S
}

This is exactly the same as Ofri's answer except I have wrapped it in a shell function and am using the less -S option to stop the wrapping of lines (makes less behaves more like a office/oocalc).

Open a new shell (or type source ~/.bashrc in your current shell) and run the command using:

csview <filename>

Google Places API also provides REST api including Places Autocomplete. https://developers.google.com/places/documentation/autocomplete

But the data retrieve from the service must use for a map.

I know this doesn't answer the question, but with Material Design (API 21+) we can change the color of the status bar by adding this line in the theme declaration in styles.xml:

<!-- MAIN THEME -->
<style name="AppTheme" parent="@android:style/Theme.Material.Light">
    <item name="android:actionBarStyle">@style/actionBarCustomization</item>
    <item name="android:spinnerDropDownItemStyle">@style/mySpinnerDropDownItemStyle</item>
    <item name="android:spinnerItemStyle">@style/mySpinnerItemStyle</item>
    <item name="android:colorButtonNormal">@color/myDarkBlue</item>
    <item name="android:statusBarColor">@color/black</item>
</style>

Notice the android:statusBarColor, where we can define the color, otherwise the default is used.

Following the previous example but with the new nbformat lib version :

import nbformat
from nbconvert import PythonExporter

def convertNotebook(notebookPath, modulePath):

  with open(notebookPath) as fh:
    nb = nbformat.reads(fh.read(), nbformat.NO_CONVERT)

  exporter = PythonExporter()
  source, meta = exporter.from_notebook_node(nb)

  with open(modulePath, 'w+') as fh:
    fh.writelines(source.encode('utf-8'))

if name in ("Jesse", "jesse"):

would be the correct way to do it.

Although, if you want to use or, the statement would be

if name == 'Jesse' or name == 'jesse':

>>> ("Jesse" or "jesse")
'Jesse'

evaluates to 'Jesse', so you're essentially not testing for 'jesse' when you do if name == ("Jesse" or "jesse"), since it only tests for equality to 'Jesse' and does not test for 'jesse', as you observed.

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

You can just inject the DOCUMENT token into the constructor and use the same functions on it

import { Inject }  from '@angular/core';
import { DOCUMENT } from '@angular/common'; 

@Component({...})
export class AppCmp {
   constructor(@Inject(DOCUMENT) document) {
      document.getElementById('el');
   }
}

Or if the element you want to get is in that component, you can use template references.

Python dictionaries have a key and a value, what you are asking for is what key(s) point to a given value.

You can only do this in a loop:

[k for (k, v) in i.iteritems() if v == 0]

Note that there can be more than one key per value in a dict; {'a': 0, 'b': 0} is perfectly legal.

If you want ordering you either need to use a list or a OrderedDict instance instead:

items = ['a', 'b', 'c']
items.index('a') # gives 0
items[0]         # gives 'a'

Quoted from https://developer.mozilla.org/en/DOM/element.click

The click method is intended to be used with INPUT elements of type button, checkbox, radio, reset or submit. Gecko does not implement the click method on other elements that might be expected to respond to mouse–clicks such as links (A elements), nor will it necessarily fire the click event of other elements.

Non–Gecko DOMs may behave differently.

Unfortunately it sounds like you have already discovered the best solution to your problem.

As a side note, I agree that your solution seems less than ideal, but if you encapsulate the functionality inside a method (much like JQuery would do) it is not so bad.

FWIW, git rebase interactive now has a "reword" option, which makes this much less painful!

I'm unclear about your question. From http://effbot.org/tkinterbook/entry.htm#patterns, it seems you just need to do an assignment after you called the delete. To add entry text to the widget, use the insert method. To replace the current text, you can call delete before you insert the new text.

e = Entry(master)
e.pack()

e.delete(0, END)
e.insert(0, "")

Could you post a bit more code?

I have been reading about using model concerns to skin-nize fat models as well as DRY up your model codes. Here is an explanation with examples:

1) DRYing up model codes

Consider a Article model, a Event model and a Comment model. An article or an event has many comments. A comment belongs to either Article or Event.

Traditionally, the models may look like this:

Comment Model:

class Comment < ActiveRecord::Base
  belongs_to :commentable, polymorphic: true
end

Article Model:

class Article < ActiveRecord::Base
  has_many :comments, as: :commentable 

  def find_first_comment
    comments.first(created_at DESC)
  end

  def self.least_commented
   #return the article with least number of comments
  end
end

Event Model

class Event < ActiveRecord::Base
  has_many :comments, as: :commentable 

  def find_first_comment
    comments.first(created_at DESC)
  end

  def self.least_commented
   #returns the event with least number of comments
  end
end

As we can notice, there is a significant piece of code common to both Event and Article. Using concerns we can extract this common code in a separate module Commentable.

For this create a commentable.rb file in app/models/concerns.

module Commentable
  extend ActiveSupport::Concern

  included do
    has_many :comments, as: :commentable
  end

  # for the given article/event returns the first comment
  def find_first_comment
    comments.first(created_at DESC)
  end

  module ClassMethods
    def least_commented
      #returns the article/event which has the least number of comments
    end
  end
end

And now your models look like this :

Comment Model:

class Comment < ActiveRecord::Base
  belongs_to :commentable, polymorphic: true
end

Article Model:

class Article < ActiveRecord::Base
  include Commentable
end

Event Model:

class Event < ActiveRecord::Base
  include Commentable
end

2) Skin-nizing Fat Models.

Consider a Event model. A event has many attenders and comments.

Typically, the event model might look like this

class Event < ActiveRecord::Base   
  has_many :comments
  has_many :attenders


  def find_first_comment
    # for the given article/event returns the first comment
  end

  def find_comments_with_word(word)
    # for the given event returns an array of comments which contain the given word
  end 

  def self.least_commented
    # finds the event which has the least number of comments
  end

  def self.most_attended
    # returns the event with most number of attendes
  end

  def has_attendee(attendee_id)
    # returns true if the event has the mentioned attendee
  end
end

Models with many associations and otherwise have tendency to accumulate more and more code and become unmanageable. Concerns provide a way to skin-nize fat modules making them more modularized and easy to understand.

The above model can be refactored using concerns as below: Create a attendable.rb and commentable.rb file in app/models/concerns/event folder

attendable.rb

module Attendable
  extend ActiveSupport::Concern

  included do 
    has_many :attenders
  end

  def has_attender(attender_id)
    # returns true if the event has the mentioned attendee
  end

  module ClassMethods
    def most_attended
      # returns the event with most number of attendes
    end
  end
end

commentable.rb

module Commentable
  extend ActiveSupport::Concern

  included do 
    has_many :comments
  end

  def find_first_comment
    # for the given article/event returns the first comment
  end

  def find_comments_with_word(word)
    # for the given event returns an array of comments which contain the given word
  end

  module ClassMethods
    def least_commented
      # finds the event which has the least number of comments
    end
  end
end

And now using Concerns, your Event model reduces to

class Event < ActiveRecord::Base
  include Commentable
  include Attendable
end

* While using concerns its advisable to go for 'domain' based grouping rather than 'technical' grouping. Domain Based grouping is like 'Commentable', 'Photoable', 'Attendable'. Technical grouping will mean 'ValidationMethods', 'FinderMethods' etc

db.data.update({'name': 'zero'}, {'$set': {'value': NumberInt(0)}})

You can also use NumberLong.

You might want to take a look at the cmdlet Tee-Object. You can pipe output to Tee and it will write to the pipeline and also to a file

This code will always fail.

As written, it says: "Look for a property named "Employee" on my DataContext property, and set it to the DataContext property". Clearly that isn't right.

To get your code to work, as is, change your window declaration to:

<Window x:Class="SampleApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:SampleApplication"
    Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
   <local:Employee/>
</Window.DataContext>

This declares a new XAML namespace (local) and sets the DataContext to an instance of the Employee class. This will cause your bindings to display the default data (from your constructor).

However, it is highly unlikely this is actually what you want. Instead, you should have a new class (call it MainViewModel) with an Employee property that you then bind to, like this:

public class MainViewModel
{
   public Employee MyEmployee { get; set; } //In reality this should utilize INotifyPropertyChanged!
}

Now your XAML becomes:

<Window x:Class="SampleApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:SampleApplication"
        Title="MainWindow" Height="350" Width="525">
    <Window.DataContext>
       <local:MainViewModel/>
    </Window.DataContext>
    ...
    <TextBox Grid.Column="1" Grid.Row="0" Margin="3" Text="{Binding MyEmployee.EmpID}" />
    <TextBox Grid.Column="1" Grid.Row="1" Margin="3" Text="{Binding MyEmployee.EmpName}" />

Now you can add other properties (of other types, names), etc. For more information, see Implementing the Model-View-ViewModel Pattern

Update February 2020

Since this answer got a lot of traction, I thought it would be best to update it with newer Angular optimizations:

1. As another answerer said, ng build --prod --build-optimizer is a good option for people using less than Angular v5. For newer versions, this is done by default with ng build --prod
2. Another option is to use module chunking/lazy loading to better split your application into smaller chunks
3. Ivy rendering engine comes by default in Angular 9, it offers better bundle sizes
4. Make sure your 3rd party deps are tree shakeable. If you're not using Rxjs v6 yet, you should be.
5. If all else fails, use a tool like webpack-bundle-analyzer to see what is causing bloat in your modules
6. Check if you files are gzipped

Some claims that using AOT compilation can reduce the vendor bundle size to 250kb. However, in BlackHoleGalaxy's example, he uses AOT compilation and is still left with a vendor bundle size of 2.75MB with ng build --prod --aot, 10x larger than the supposed 250kb. This is not out of the norm for angular2 applications, even if you are using v4.0. 2.75MB is still too large for anyone who really cares about performance, especially on a mobile device.

There are a few things you can do to help the performance of your application:

1) AOT & Tree Shaking (angular-cli does this out of the box). With Angular 9 AOT is by default on prod and dev environment.

2) Using Angular Universal A.K.A. server-side rendering (not in cli)

3) Web Workers (again, not in cli, but a very requested feature)
see: https://github.com/angular/angular-cli/issues/2305

4) Service Workers
see: https://github.com/angular/angular-cli/issues/4006

You may not need all of these in a single application, but these are some of the options that are currently present for optimizing Angular performance. I believe/hope Google is aware of the out of the box shortcomings in terms of performance and plans to improve this in the future.

Here is a reference that talks more in depth about some of the concepts i mentioned above:

https://medium.com/@areai51/the-4-stages-of-perf-tuning-for-your-angular2-app-922ce5c1b294

Please look here about creating a shape drawable http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape

Once you have done this, in the XML for your button set android:background="@drawable/your_button_border"

another option would be to give the span display:table; and center it via margin:0 auto;

span {
display:table;
margin:0 auto;
}

A SurfaceView is a custom view in Android that can be used to drawn inside it.

The main difference between a View and a SurfaceView is that a View is drawn in the UI Thread, which is used for all the user interaction.

If you want to update the UI rapidly enough and render a good amount of information in it, a SurfaceView is a better choice.

But there are a few technical insides to the SurfaceView:

1. They are not hardware accelerated.

2. Normal views are rendered when you call the methods invalidate or postInvalidate(), but this does not mean the view will be immediately updated (A VSYNC will be sent, and the OS decides when it gets updated. The SurfaceView can be immediately updated.

3. A SurfaceView has an allocated surface buffer, so it is more costly

You can also replace without a regular expression.

while(str.indexOf('  ')!=-1)str.replace('  ',' ');

Update: I figured this out. On my ScrollView, I needed to override the onInterceptTouchEvent method to only intercept the touch event if the Y motion is > the X motion. It seems like the default behavior of a ScrollView is to intercept the touch event whenever there is ANY Y motion. So with the fix, the ScrollView will only intercept the event if the user is deliberately scrolling in the Y direction and in that case pass off the ACTION_CANCEL to the children.

Here is the code for my Scroll View class that contains the HorizontalScrollView:

public class CustomScrollView extends ScrollView {
    private GestureDetector mGestureDetector;

    public CustomScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
        mGestureDetector = new GestureDetector(context, new YScrollDetector());
        setFadingEdgeLength(0);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return super.onInterceptTouchEvent(ev) && mGestureDetector.onTouchEvent(ev);
    }

    // Return false if we're scrolling in the x direction  
    class YScrollDetector extends SimpleOnGestureListener {
        @Override
        public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {             
            return Math.abs(distanceY) > Math.abs(distanceX);
        }
    }
}

In case that you need to add the http redirect in many sites, you could use it as a c# console program:

   class Program
{
    static int Main(string[] args)
    {
        if (args.Length < 3)
        {
            Console.WriteLine("Please enter an argument: for example insert-redirect ./web.config http://stackoverflow.com");
            return 1;
        }

        if (args.Length == 3)
        {
            if (args[0].ToLower() == "-insert-redirect")
            {
                var path = args[1];
                var value = args[2];

                if (InsertRedirect(path, value))
                    Console.WriteLine("Redirect added.");
                return 0;
            }
        }

        Console.WriteLine("Wrong parameters.");
        return 1;

    }

    static bool InsertRedirect(string path, string value)
    {
        try
        {
            XmlDocument doc = new XmlDocument();

            doc.Load(path);

            // This should find the appSettings node (should be only one):
            XmlNode nodeAppSettings = doc.SelectSingleNode("//system.webServer");

            var existNode = nodeAppSettings.SelectSingleNode("httpRedirect");
            if (existNode != null)
                return false;

            // Create new <add> node
            XmlNode nodeNewKey = doc.CreateElement("httpRedirect");

            XmlAttribute attributeEnable = doc.CreateAttribute("enabled");
            XmlAttribute attributeDestination = doc.CreateAttribute("destination");
            //XmlAttribute attributeResponseStatus = doc.CreateAttribute("httpResponseStatus");

            // Assign values to both - the key and the value attributes:

            attributeEnable.Value = "true";
            attributeDestination.Value = value;
            //attributeResponseStatus.Value = "Permanent";

            // Add both attributes to the newly created node:
            nodeNewKey.Attributes.Append(attributeEnable);
            nodeNewKey.Attributes.Append(attributeDestination);
            //nodeNewKey.Attributes.Append(attributeResponseStatus);

            // Add the node under the 
            nodeAppSettings.AppendChild(nodeNewKey);
            doc.Save(path);

            return true;
        }
        catch (Exception e)
        {
            Console.WriteLine($"Exception adding redirect: {e.Message}");
            return false;
        }
    }
}

We can use the raw_input() function in Python 2 and the input() function in Python 3. By default the input function takes an input in string format. For other data type you have to cast the user input.

In Python 2 we use the raw_input() function. It waits for the user to type some input and press return and we need to store the value in a variable by casting as our desire data type. Be careful when using type casting

x = raw_input("Enter a number: ") #String input

x = int(raw_input("Enter a number: ")) #integer input

x = float(raw_input("Enter a float number: ")) #float input

x = eval(raw_input("Enter a float number: ")) #eval input

In Python 3 we use the input() function which returns a user input value.

x = input("Enter a number: ") #String input

If you enter a string, int, float, eval it will take as string input

x = int(input("Enter a number: ")) #integer input

If you enter a string for int cast ValueError: invalid literal for int() with base 10:

x = float(input("Enter a float number: ")) #float input

If you enter a string for float cast ValueError: could not convert string to float

x = eval(input("Enter a float number: ")) #eval input

If you enter a string for eval cast NameError: name ' ' is not defined Those error also applicable for Python 2.

Here is the Angular version of LightBox. Just Awesome :)

If you leave out the brackets then PHP will assign the keys by default.

Try this:

$votes = $row['votes_up']; 
$votes = $row['votes_down']; 

write direct password into config>database.php

C# 3.0 :

char[] az = Enumerable.Range('a', 'z' - 'a' + 1).Select(i => (Char)i).ToArray();
foreach (var c in az)
{
    Console.WriteLine(c);
}

yes it does work even if the only overload of Enumerable.Range accepts int parameters ;-)

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

Video file example (HTML + Javascript):

function upload_check()
{

    var max = document.getElementById("max_id").value;

    if(upl.files[0].size > max)
    {
       alert("File too big!");
       upl.value = "";
    }
};

<form action="some_script" method="post" enctype="multipart/form-data">
    <input id="max_id" type="hidden" name="MAX_FILE_SIZE" value="250000000" />
    <input onchange="upload_check()" id="file_id" type="file" name="file_name" accept="video/*" />
    <input type="submit" value="Upload"/>

1. Go to Xcode preferences by clicking on "Xcode" in the left hand side upper corner.

2. Select "Text Editing".

3. Select "Show: Line numbers" and click on check box for enable it.

4. Close it.

Then you will see the line number in Xcode.

I had huge problems with this

First I tried .clear() then I tried .destroy() and I tried setting my chart reference to null

What finally fixed the issue for me: deleting the <canvas> element and then reappending a new <canvas> to the parent container

There's a million ways to do this:

var resetCanvas = function () {
  $('#results-graph').remove(); // this is my <canvas> element
  $('#graph-container').append('<canvas id="results-graph"><canvas>');
  canvas = document.querySelector('#results-graph'); // why use jQuery?
  ctx = canvas.getContext('2d');
  ctx.canvas.width = $('#graph').width(); // resize to parent width
  ctx.canvas.height = $('#graph').height(); // resize to parent height

  var x = canvas.width/2;
  var y = canvas.height/2;
  ctx.font = '10pt Verdana';
  ctx.textAlign = 'center';
  ctx.fillText('This text is centered on the canvas', x, y);
};

Spring Boot 1.4 introduced testing annotation called @MockBean. So now mocking and spying on Spring beans is natively supported by Spring Boot.

if you are using same date format and have select query where date in oracle :

   select count(id) from Table_name where TO_DATE(Column_date)='07-OCT-2015';

To_DATE provided by oracle

I have made a cheat-sheet I think can be useful to others. In all examples, you can remove the format_sql property if you want to keep the logged queries on a single line (no pretty printing).

Pretty print SQL queries to standard out without parameters of prepared statements and without optimizations of a logging framework:

I recently published some Excel templates for Scrum, the Product Backlog includes a Release Burndown and the Sprint Backlog includes a Sprint Burndown.

Get them here: http://www.phdesign.com.au/general/excel-templates-for-scrum-product-and-sprint-backlogs

One way is to add this to a new c# class or HtmlExtensions class

public static class HtmlExtensions
{
    public static MvcHtmlString Image(this HtmlHelper html, byte[] image)
    {
        var img = String.Format("data:image/jpg;base64,{0}", Convert.ToBase64String(image));
        return new MvcHtmlString("<img src='" + img + "' />");
    }
}

then you can do this in any view

@Html.Image(Model.ImgBytes)

When you check out a specific commit in git, you end up in a detached head state...that is, your working copy no longer reflects the state of a named reference (like "master"). This is useful for examining the past state of the repository, but not what you want if you're actually trying to revert changes.

If you have made changes to a particular file and you simply want to discard them, you can use the checkout command like this:

git checkout myfile

This will discard any uncommitted changes and revert the file to whatever state it has in the head of your current branch. If you want to discard changes that you have already committed, you may want to use the reset command. For example, this will reset the repository to the state of the previous commit, discarding any subsequent changes:

git reset --hard HEAD^

However, if you are sharing the repository with other people, a git reset can be disruptive (because it erases a portion of the repository history). If you have already shared changes with other people, you generally want to look at git revert instead, which generates an "anticommit" -- that is, it creates a new commit that "undoes" the changes in question.

The Git Book has more details.

image

Variable-length binary data from 0 through 2^31-1 (2,147,483,647) bytes. Still it IS supported to use image datatype, but be aware of:

https://docs.microsoft.com/en-us/sql/t-sql/data-types/binary-and-varbinary-transact-sql

varbinary [ ( n | max) ]

Variable-length binary data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of the data entered + 2 bytes. The data that is entered can be 0 bytes in length. The ANSI SQL synonym for varbinary is binary varying.

So both are equally in size (2GB). But be aware of:

https://docs.microsoft.com/en-us/sql/database-engine/deprecated-database-engine-features-in-sql-server-2016#features-not-supported-in-a-future-version-of-sql-server

Though the end of "image" datatype is still not determined, you should use the "future" proof equivalent.

But you have to ask yourself: why storing BLOBS in a Column?

https://docs.microsoft.com/en-us/sql/relational-databases/blob/compare-options-for-storing-blobs-sql-server

I would probably use $('.mydiv').is('#foo'); That said if you know the Id why wouldnt you just apply it to the selector in the first place?

Per the developers, this error is not an actual failure, but rather "misleading error reports". This bug is fixed in version 40, which is available on the canary and dev channels as of 25 Oct.

Patch

For sentOs, it's works for me At first stop service by sudo service jenkins stop

Than remove by sudo yum remove jenkins

The best secure method is to use the crontab. ie Save all your commands in a database say, mysql table and create a cronjob to read these mysql entreis and execute via exec() or shell_exec(). Please read this link for more detailed information.

Non textual widgets need a content description in some ways to describe textually the image so that screens readers to be able to describe the user interface. You can ignore the property xmlns:tools="http://schemas.android.com/tools"
tools:ignore="contentDescription" or define the property android:contentDescription="your description"

First check the list:-

git stash list

copy the index you wanted to pop from the stash list

git stash pop stash@{index_number}

eg.:

git stash pop stash@{1}

I prefer to hunt down and fix problems instead of suppressing logs whenever possible. After a couple days of observing this issue in my app, I realized I was setting listeners on the req.socket in an Express middleware to catch socket io errors that kept popping up. At some point, I learned that that was not necessary, but I kept the listeners around anyway. I just removed them and the error you are experiencing went away. I verified it was the cause by running requests to my server with and without the following middleware:

socketEventsHandler(req, res, next) {
        req.socket.on("error", function(err) {
            console.error('------REQ ERROR')
            console.error(err.stack)
        });
        res.socket.on("error", function(err) {
            console.error('------RES ERROR')
            console.error(err.stack)
        });
        next();
    }

Removing that middleware stopped the warning you are seeing. I would look around your code and try to find anywhere you may be setting up listeners that you don't need.

The first way is the older standard. The second method was introduced in SQL-92, http://en.wikipedia.org/wiki/SQL. The complete standard can be viewed at http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt .

It took many years before database companies adopted the SQL-92 standard.

So the reason why the second method is preferred, it is the SQL standard according the ANSI and ISO standards committee.

There is an old plugin called HEX Editor here.

According to this question on Super User it does not work on newer versions of Notepad++ and might have some stability issues, but it still could be useful depending on your needs.

typename and class are interchangeable in the basic case of specifying a template:

template<class T>
class Foo
{
};

and

template<typename T>
class Foo
{
};

are equivalent.

Having said that, there are specific cases where there is a difference between typename and class.

The first one is in the case of dependent types. typename is used to declare when you are referencing a nested type that depends on another template parameter, such as the typedef in this example:

template<typename param_t>
class Foo
{
    typedef typename param_t::baz sub_t;
};

The second one you actually show in your question, though you might not realize it:

template < template < typename, typename > class Container, typename Type >

When specifying a template template, the class keyword MUST be used as above -- it is not interchangeable with typename in this case (note: since C++17 both keywords are allowed in this case).

You also must use class when explicitly instantiating a template:

template class Foo<int>;

I'm sure that there are other cases that I've missed, but the bottom line is: these two keywords are not equivalent, and these are some common cases where you need to use one or the other.

var total = 0
grades.forEach(function (grade) {
    total += grade        
});
console.log(total / grades.length)

You could also just use the NSUUID API:

let uuid = NSUUID()

If you want to get the string value back out, you can use uuid.UUIDString.

Note that NSUUID is available from iOS 6 and up.

PHP > 5.3 use fgetcsv() or str_getcsv(). Couldn't be simpler.

First create table without auto_increment,

CREATE TABLE `members`(
    `id` int(11) NOT NULL,
    `memberid` VARCHAR( 30 ) NOT NULL ,
    `Time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ,
    `firstname` VARCHAR( 50 ) NULL ,
    `lastname` VARCHAR( 50 ) NULL
    PRIMARY KEY (memberid) 
) ENGINE = MYISAM;

after set id as index,

ALTER TABLE `members` ADD INDEX(`id`);

after set id as auto_increment,

ALTER TABLE `members` CHANGE `id` `id` INT(11) NOT NULL AUTO_INCREMENT;

Or

CREATE TABLE IF NOT EXISTS `members` (
    `id` int(11) NOT NULL,
    `memberid` VARCHAR( 30 ) NOT NULL ,
    `Time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ,
    `firstname` VARCHAR( 50 ) NULL ,
    `lastname` VARCHAR( 50 ) NULL,
      PRIMARY KEY (`memberid`),
      KEY `id` (`id`)
) ENGINE=MYISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

you can specify fields like this:

LOAD XML LOCAL INFILE '/pathtofile/file.xml' 
INTO TABLE my_tablename(personal_number, firstname, ...); 

You should be able to use the macros defined in stdint.h. In particular INTPTR_MAX is exactly the value you need.

#include <cstdint>
#if INTPTR_MAX == INT32_MAX
    #define THIS_IS_32_BIT_ENVIRONMENT
#elif INTPTR_MAX == INT64_MAX
    #define THIS_IS_64_BIT_ENVIRONMENT
#else
    #error "Environment not 32 or 64-bit."
#endif

Some (all?) versions of Microsoft's compiler don't come with stdint.h. Not sure why, since it's a standard file. Here's a version you can use: http://msinttypes.googlecode.com/svn/trunk/stdint.h

It's declared inside a closure, which means it can only be accessed there. If you want a variable accessible globally, you can remove the var:

$(function(){
    value = "10";
});
value; // "10"

This is equivalent to writing window.value = "10";.

I think this first failed because you are ordering value which is null. If Delivery is a foreign key associated table then you should include this table first, example below:

var itemList = from t in ctn.Items.Include(x=>x.Delivery)
                    where !t.Items && t.DeliverySelection
                    orderby t.Delivery.SubmissionDate descending
                    select t;

For IE

If you are using IE then go to print preview ( right click on document -> print preview ), go to settings and there is option "print background color and images", select that option and try.

Generally if the installation went smoothly, it will create the desktop icons/folders. Maybe check the installation summary log to see if there's any underlying errors.

It should be located C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log(date stamp)\

function is_json($input) {

    $input = trim($input);

    if (substr($input,0,1)!='{' OR substr($input,-1,1)!='}')
        return false;

    return is_array(@json_decode($input, true));
}

Forget float, margin and html 3/5. The mail is very obsolete. You need do all with table. One line = one table. You need margin or padding ? Do another column.

Codepen

Example : i need one line with 1 One Picture of 40*40 2 One margin of 10 px 3 One text of 400px

I start my line :

<table style=" background-repeat:no-repeat; width:450px;margin:0;" cellpadding="0" cellspacing="0" border="0">
   <tr style="height:40px; width:450px; margin:0;">
     <td style="height:40px; width:40px; margin:0;">
        <img src="" style="width=40px;height40;margin:0;display:block"
     </td>
     <td style="height:40px; width:10px; margin:0;">        
     </td>
     <td style="height:40px; width:400px; margin:0;">
     <p style=" margin:0;"> my text   </p>
     </td>
   </tr>
</table>

This is code that I have effectively used before, passing "/" as the strPath parameter.

public static Cookie eraseCookie(String strCookieName, String strPath) {
    Cookie cookie = new Cookie(strCookieName, "");
    cookie.setMaxAge(0);
    cookie.setPath(strPath);

    return cookie;
}

Without jQuery:

document.getElementById('file').onchange = function(){

  var file = this.files[0];

  var reader = new FileReader();
  reader.onload = function(progressEvent){
    // Entire file
    console.log(this.result);

    // By lines
    var lines = this.result.split('\n');
    for(var line = 0; line < lines.length; line++){
      console.log(lines[line]);
    }
  };
  reader.readAsText(file);
};

HTML:

<input type="file" name="file" id="file">

Remember to put your javascript code after the file field is rendered.

This is how I did it.

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--disable-extensions')

chrome = webdriver.Chrome(chrome_options=chrome_options)

Alternative by terminal with no permission

The pg documentation at NOTES say

The path will be interpreted relative to the working directory of the server process (normally the cluster's data directory), not the client's working directory.

So, gerally, using psql or any client, even in a local server, you have problems ... And, if you're expressing COPY command for other users, eg. at a Github README, the reader will have problems ...

The only way to express relative path with client permissions is using STDIN,

When STDIN or STDOUT is specified, data is transmitted via the connection between the client and the server.

as remembered here:

psql -h remotehost -d remote_mydb -U myuser -c \
   "copy mytable (column1, column2) from STDIN with delimiter as ','" \
   < ./relative_path/file.csv

If you have even the relative pathname (in this case it appears to be ./) you can open files relative to your script file(s). I use Perl, but the same general solution can apply: I split the directory into an array of folders, then pop off the last element (the script), then push (or for you, append) on whatever I want, and then join them together again, and BAM! I have a working pathname that points to exactly where I expect it to point, relative or absolute.

Of course, there are better solutions, as posted. I just kind of like mine.

I've been working with JetBrains dotTrace for WinForms and Console Apps (not tested on ASP.net yet), and it works quite well:

They recently also added a "Personal License" that is significantly cheaper than the corporate one. Still, if anyone else knows some cheaper or even free ones, I'd like to hear as well :-)

Provide random.choice() with a pre-weighted list:

Solution & Test:

import random

options = ['a', 'b', 'c', 'd']
weights = [1, 2, 5, 2]

weighted_options = [[opt]*wgt for opt, wgt in zip(options, weights)]
weighted_options = [opt for sublist in weighted_options for opt in sublist]
print(weighted_options)

# test

counts = {c: 0 for c in options}
for x in range(10000):
    counts[random.choice(weighted_options)] += 1

for opt, wgt in zip(options, weights):
    wgt_r = counts[opt] / 10000 * sum(weights)
    print(opt, counts[opt], wgt, wgt_r)

Output:

['a', 'b', 'b', 'c', 'c', 'c', 'c', 'c', 'd', 'd']
a 1025 1 1.025
b 1948 2 1.948
c 5019 5 5.019
d 2008 2 2.008

From my limited experience, I would say that the following two scenario could cause response status code: 0, keep in mind; their could be more, but I know of those two:

• your connection maybe responding slowly.
• or maybe the the back-end server is not available.

the thing is, status: 0 is slightly generic, and their could be more use cases that trigger an empty response body.

This is the procedure that seems simplest to me:

SharedPreferences sp = getSharedPreferences("MySharedPrefs", MODE_PRIVATE);
SharedPreferences.Editor e = sp.edit();

    if (sp.getString("sharedString", null).equals("true")
            || sp.getString("sharedString", null) == null) {
        e.putString("sharedString", "false").commit();
        // Do something
    } else {
        // Do something else
    }

Rewrite your query to:

select iu from internal_uddi iu where iu.urn....

To check for a timeout, I believe you check the value of ex.Number. If it is -2, then you have a timeout situation.

-2 is the error code for timeout, returned from DBNETLIB, the MDAC driver for SQL Server. This can be seen by downloading Reflector, and looking under System.Data.SqlClient.TdsEnums for TIMEOUT_EXPIRED.

Your code would read:

if (ex.Number == -2)
{
     //handle timeout
}

Code to demonstrate failure:

try
{
    SqlConnection sql = new SqlConnection(@"Network Library=DBMSSOCN;Data Source=YourServer,1433;Initial Catalog=YourDB;Integrated Security=SSPI;");
    sql.Open();

    SqlCommand cmd = sql.CreateCommand();
    cmd.CommandText = "DECLARE @i int WHILE EXISTS (SELECT 1 from sysobjects) BEGIN SELECT @i = 1 END";
    cmd.ExecuteNonQuery(); // This line will timeout.

    cmd.Dispose();
    sql.Close();
}
catch (SqlException ex)
{
    if (ex.Number == -2) {
        Console.WriteLine ("Timeout occurred");
    }
}

You have a selector ul on line 252 which is setting list-style: square outside none (a square bullet). You'll have to change it to list-style: none or just remove the line.

If you only want to remove the bullets from that specific instance, you can use the specific selector for that list and its items as follows:

ul#groups-list.items-list { list-style: none }

You can simply do this:

timestamps.sort(reverse=True)

The most common way to run a .sh file is using the sh command:

C:\>sh my-script-test.sh 

other good option is installing CygWin

in Windows the home is located in:

C:\cygwin64\home\[user]

for example i execute my my-script-test.sh file using the bash command as:

jorgesys@INT024P ~$ bash /home/[user]/my-script-test.sh 

You can use the HTML5 pattern attribute or use JavaScript.

The pattern could look for example like this:

<input id="groupidtext" type="text" pattern="(.){6,6}" style="width: 100px;" maxlength="6" />

But the pattern attribute will only work with HTML5 browsers. For old browsers you'll need JavaScript.

As suggested in the comments to add, this will only work as soon as a form is about to be submitted. If this input is not in a form and you need validation as a user types, use JavaScript.

A general tip , if you get confused by any of new JS syntax and how it will compile , you can check babel. For example copying your code in babel and selecting the es2015 preset will give an output like this

handleChange = function handleChange(field) {
 return function (e) {
 e.preventDefault();
  // Do something here
   };
 };

You can also destroy the old datatable by using the following code before creating the new datatable:

$("#example").dataTable().fnDestroy();

The true entry point to any application is a static method. If the Java language supported an instance method as the "entry point", then the runtime would need implement it internally as a static method which constructed an instance of the object followed by calling the instance method.

With that out of the way, I'll examine the rationale for choosing a specific one of the following three options:

1. A static void main() as we see it today.
2. An instance method void main() called on a freshly constructed object.
3. Using the constructor of a type as the entry point (e.g., if the entry class was called Program, then the execution would effectively consist of new Program()).

Breakdown:

static void main()

1. Calls the static constructor of the enclosing class.
2. Calls the static method main().

void main()

1. Calls the static constructor of the enclosing class.
2. Constructs an instance of the enclosing class by effectively calling new ClassName().
3. Calls the instance method main().

new ClassName()

1. Calls the static constructor of the enclosing class.
2. Constructs an instance of the class (then does nothing with it and simply returns).

Rationale:

I'll go in reverse order for this one.

Keep in mind that one of the design goals of Java was to emphasize (require when possible) good object-oriented programming practices. In this context, the constructor of an object initializes the object, but should not be responsible for the object's behavior. Therefore, a specification that gave an entry point of new ClassName() would confuse the situation for new Java developers by forcing an exception to the design of an "ideal" constructor on every application.

By making main() an instance method, the above problem is certainly solved. However, it creates complexity by requiring the specification to list the signature of the entry class's constructor as well as the signature of the main() method.

In summary, specifying a static void main() creates a specification with the least complexity while adhering to the principle of placing behavior into methods. Considering how straightforward it is to implement a main() method which itself constructs an instance of a class and calls an instance method, there is no real advantage to specifying main() as an instance method.

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    editString = ed.getText().toString();
    if(editString.equals("1")){

        toggle.setTextOff("TOGGLE ON");
        toggle.setChecked(true);

    }
    else if(editString.equals("0")){

        toggle.setTextOn("TOGGLE OFF");
        toggle.setChecked(false);

    }
}

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

This below-given commands worked for me.

npm cache clean --force
npm install -g webpack

Note - Run these commands as administrator. Once installed then close your command prompt and restart it to see the applied changes.

select * from table where 
(dtColumn between #3/1/2009# and #3/31/2009#) and 
(hour(dtColumn) between 6 and 22) and 
(weekday(dtColumn, 1) between 2 and 4) 

I agree with previous comment that might be best to consider a different approach. My suggest would be write a console application and use the windows scheduler:

This will:

• Reduce plumbing code that replicates scheduler behaviour
• Provide greater flexibility in terms of scheduling behaviour (e.g. only run on weekends) with all scheduling logic abstracted from application code
• Utilise the command line arguments for parameters without having to setup configuration values in config files etc
• Far easier to debug/test during development
• Allow a support user to execute by invoking the console application directly (e.g. useful during support situations)

d = document.createElement('div');
$(d).addClass(classname)
    .html(text)
    .appendTo($("#myDiv")) //main div
.click(function () {
    $(this).remove();
})
    .hide()
    .slideToggle(300)
    .delay(2500)
    .slideToggle(300)
    .queue(function () {
    $(this).remove();
});

For this you can simply use the "HttpWebRequest" and "HttpWebResponse" classes in .net.

Below is a sample console app I wrote to demonstrate how easy this is.

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            string url = "www.somewhere.com";       
            string fileName = @"C:\output.file";

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Timeout = 5000;

            try
            {
                using (WebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    using (FileStream stream = new FileStream(fileName, FileMode.Create, FileAccess.Write))
                    {
                        byte[] bytes = ReadFully(response.GetResponseStream());

                        stream.Write(bytes, 0, bytes.Length);
                    }
                }
            }
            catch (WebException)
            {
                Console.WriteLine("Error Occured");
            }
        }

        public static byte[] ReadFully(Stream input)
        {
            byte[] buffer = new byte[16 * 1024];
            using (MemoryStream ms = new MemoryStream())
            {
                int read;
                while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
                {
                    ms.Write(buffer, 0, read);
                }
                return ms.ToArray();
            }
        }
    }
}

Enjoy!

You have missed out the field name id in the second NOT LIKE. Try:

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

The AND in the where clause joins 2 full condition expressions such as id NOT LIKE '1%' and can't be used to list multiple values that the id is 'not like'.

TL;DR: Use __builtin intrinsics instead; they might happen to help.

I was able to make gcc 4.8.4 (and even 4.7.3 on gcc.godbolt.org) generate optimal code for this by using __builtin_popcountll which uses the same assembly instruction, but gets lucky and happens to make code that doesn't have an unexpectedly long loop-carried dependency because of the false dependency bug.

I am not 100% sure of my benchmarking code, but objdump output seems to share my views. I use some other tricks (++i vs i++) to make the compiler unroll loop for me without any movl instruction (strange behaviour, I must say).

according to JAVA documentation, the JDK should be installed in this path:

/Library/Java/JavaVirtualMachines/jdkmajor.minor.macro[_update].jdk

See the uninstall JDK part at https://docs.oracle.com/javase/8/docs/technotes/guides/install/mac_jdk.html

So if you can find such folder then the JDK is installed

Based on your comments in this answer, I do what you're trying to do like this:

module.exports = function (app, db) {
    var module = {};

    module.auth = function (req, res) {
        // This will be available 'outside'.
        // Authy stuff that can be used outside...
    };

    // Other stuff...
    module.pickle = function(cucumber, herbs, vinegar) {
        // This will be available 'outside'.
        // Pickling stuff...
    };

    function jarThemPickles(pickle, jar) {
        // This will be NOT available 'outside'.
        // Pickling stuff...

        return pickleJar;
    };

    return module;
};

I structure pretty much all my modules like that. Seems to work well for me.

Be advised this answer is three years old. I wrote it based mostly on a experience with .Net 4.0, and very little with 4.5 especially with async-await. Generally speaking it's a nice simple solution, but it sometimes breaks things. Please read the discussion in the comments.

.Net 4.5

Just use this:

// For Task<T>: will block until the task is completed...
var result = task.Result; 

// For Task (not Task<T>): will block until the task is completed...
task2.RunSynchronously();

See: TaskAwaiter, Task.Result, Task.RunSynchronously

.Net 4.0

Use this:

var x = (IAsyncResult)task;
task.Start();

x.AsyncWaitHandle.WaitOne();

...or this:

task.Start();
task.Wait();

Semaphore can be counted, while mutex can only count to 1.

Suppose you have a thread running which accepts client connections. This thread can handle 10 clients simultaneously. Then each new client sets the semaphore until it reaches 10. When the Semaphore has 10 flags, then your thread won't accept new connections

Mutex are usually used for guarding stuff. Suppose your 10 clients can access multiple parts of the system. Then you can protect a part of the system with a mutex so when 1 client is connected to that sub-system, no one else should have access. You can use a Semaphore for this purpose too. A mutex is a "Mutual Exclusion Semaphore".

I've used something similar to BM2ilabs's answer in the past to style the tick in checkboxes. This technique uses only a single pseudo element so it preserves the semantic HTML and there is no reason for additional HTML elements.

I found the solution for the above program, which had the goal of signing in to http://rediff.com

public class Handle_popupNAlert
{
    public static void main(String[] args ) throws InterruptedException
    {
        WebDriver driver= new FirefoxDriver(); 
        driver.get("http://www.rediff.com/");
        WebElement sign = driver.findElement(By.xpath("//html/body/div[3]/div[3]/span[4]/span/a"));
        sign.click();

        Set<String> windowId = driver.getWindowHandles();    // get  window id of current window
        Iterator<String> itererator = windowId.iterator();   

        String mainWinID = itererator.next();
        String  newAdwinID = itererator.next();

        driver.switchTo().window(newAdwinID);
        System.out.println(driver.getTitle());
        Thread.sleep(3000);
        driver.close();

        driver.switchTo().window(mainWinID);
        System.out.println(driver.getTitle());
        Thread.sleep(2000);

        WebElement email_id= driver.findElement(By.xpath("//*[@id='c_uname']"));
        email_id.sendKeys("hi");
        Thread.sleep(5000);

        driver.close();
        driver.quit();
    }  
}

This may be sufficient in many cases

stream.findAny().isPresent()

PFX files are PKCS#12 Personal Information Exchange Syntax Standard bundles. They can include arbitrary number of private keys with accompanying X.509 certificates and a certificate authority chain (set certificates).

If you want to extract client certificates, you can use OpenSSL's PKCS12 tool.

openssl pkcs12 -in input.pfx -out mycerts.crt -nokeys -clcerts

The command above will output certificate(s) in PEM format. The ".crt" file extension is handled by both macOS and Window.

You mention ".cer" extension in the question which is conventionally used for the DER encoded files. A binary encoding. Try the ".crt" file first and if it's not accepted, easy to convert from PEM to DER:

openssl x509 -inform pem -in mycerts.crt -outform der -out mycerts.cer

Basically, you need two jobs. One to check whether files changed and one to do the actual build:

Job #1

This should be triggered on changes in your Git repository. It then tests whether the path you specify ("src" here) has changes and then uses Jenkins' CLI to trigger a second job.

export JENKINS_CLI="java -jar /var/run/jenkins/war/WEB-INF/jenkins-cli.jar"
export JENKINS_URL=http://localhost:8080/
export GIT_REVISION=`git rev-parse HEAD`
export STATUSFILE=$WORKSPACE/status_$BUILD_ID.txt

# Figure out, whether "src" has changed in the last commit
git diff-tree --name-only HEAD | grep src

# Exit with success if it didn't
$? || exit 0

# Trigger second job
$JENKINS_CLI build job2 -p GIT_REVISION=$GIT_REVISION -s

Job #2

Configure this job to take a parameter GIT_REVISION like so, to make sure you're building exactly the revision the first job chose to build.

Printf is actually pretty good to use if size matters. Meaning if you are running a program where memory is an issue, then printf is actually a very good and under rater solution. Cout essentially shifts bits over to make room for the string, while printf just takes in some sort of parameters and prints it to the screen. If you were to compile a simple hello world program, printf would be able to compile it in less than 60, 000 bits as opposed to cout, it would take over 1 million bits to compile.

For your situation, id suggest using cout simply because it is much more convenient to use. Although, I would argue that printf is something good to know.

Since the actual ScrollView is encapsulated in a CoordinatorLayout with a Toolbar ...

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay"/>

    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/list"/>

</android.support.design.widget.CoordinatorLayout>

... I had to define android:layout_marginTop="?attr/actionBarSize" to make the scrolling working:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="?attr/actionBarSize">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <!-- UI elements here -->

    </android.support.constraint.ConstraintLayout>

</ScrollView>

Above also works with NestedScrollView instead of ScrollView. Defining android:fillViewport="true" is not needed for me.

MutationObserver = window.MutationObserver || window.WebKitMutationObserver;

var observer = new MutationObserver(function(mutations, observer) {
    // fired when a mutation occurs
    console.log(mutations, observer);
    // ...
});

// define what element should be observed by the observer
// and what types of mutations trigger the callback
observer.observe(document, {
  subtree: true,
  attributes: true
  //...
});

Some of the answers here suggest using setTimeout to delay the process of focusing on the target element. One of them mentions that the target is inside a modal dialog. I cannot comment further on the correctness of the setTimeoutsolution without knowing the specific details of where it was used. However, I thought I should provide an answer here to help out people who run into this thread just as I did

The simple fact of the matter is that you cannot focus on an element which is not yet visible. If you run into this problem ensure that the target is actually visible when the attempt to focus it is made. In my own case I was doing something along these lines

$('#elementid').animate({left:0,duration:'slow'});
$('#elementid').focus();

This did not work. I only realized what was going on when I executed $('#elementid').focus()` from the console which did work. The difference - in my code above the target there is no certainty that the target will infact be visible since the animation may not be complete. And there lies the clue

$('#elementid').animate({left:0,duration:'slow',complete:focusFunction});

function focusFunction(){$('#elementid').focus();}

works just as expected. I too had initially put in a setTimeout solution and it worked too. However, an arbitrarily chosen timeout is bound to break the solution sooner or later depending on how slowly the host device goes about the process of ensuring that the target element is visible.

First you need to reset VS setting (tools > option > Export Settings > Reset all settings) and click Resharper button(Option > Environment > Keyboard&Menu > Keyboard shortcuts) select item you want to use and apply scheme.

It's work for me on visual studio 2012.

Daniel answer is right on the spot. If you want to query more than one field do this:

Employee.objects.values_list('eng_name','rank')

This will return list of tuples. You cannot use named=Ture when querying more than one field.

Moreover if you know that only one field exists with that info and you know the pk id then do this:

Employee.objects.values_list('eng_name','rank').get(pk=1)

Setter: public void setCurrent(boolean val)
Getter: public boolean getCurrent()

For booleans you can also use

public boolean isCurrent()

The best solution for me is:

// Add key/value
var dict = new Dictionary<string, string>();
dict.Add("Content-Type", "application/x-www-form-urlencoded");

// Execute post method
using (var response = httpClient.PostAsync(path, new FormUrlEncodedContent(dict))){}

How can I use the binary operator alongside the date filter?

<span class="gallery-date">{{gallery.date | date:'mediumDate' || "Date Empty"}}</span>

you also try:

<span class="gallery-date">{{ gallery.date == 'NULL' ? 'mediumDate' : "gallery.date"}}</span>

Suppose you have mulitple record for same date or leave_type but different id and you want the maximum no of id for same date or leave_type as i also sucked with this issue, so Yes you can do it with the following query:

select * from tabel_name where employee_no='123' and id=(
   select max(id) from table_name where employee_no='123' and leave_type='5'
)

To send json to the server, you first have to create json

function sendData() {
    $.ajax({
        url: '/helloworld',
        type: 'POST',
        contentType: 'application/json',
        data: JSON.stringify({
            name:"Bob",
            ...
        }),
        dataType: 'json'
    });
}

This is how you would structure the ajax request to send the json as a post var.

function sendData() {
    $.ajax({
        url: '/helloworld',
        type: 'POST',
        data: { json: JSON.stringify({
            name:"Bob",
            ...
        })},
        dataType: 'json'
    });
}

The json will now be in the json post var.

BigDecimal offers a string constructor. You'll need to strip all commas from the number, via via an regex or String filteredString=inString.replaceAll(",","").

You then simply call BigDecimal myBigD=new BigDecimal(filteredString);

You can also create a NumberFormat and call setParseBigDecimal(true). Then parse( will give you a BigDecimal without worrying about manually formatting.

You could probably use an inheritance structure although the more I played with this the dirtier I felt.

Wait, are you really needing to render it using javascript?

Be aware that in HTML5 there is srcdoc, which can do that for you! (The drawback is that IE/EDGE does not support it yet https://caniuse.com/#feat=iframe-srcdoc)

See here [srcdoc]: https://www.w3schools.com/tags/att_iframe_srcdoc.asp

Another thing to note is that if you want to avoid the interference of the js code inside and outside you should consider using the sandbox mode.

See here [sandbox]: https://www.w3schools.com/tags/att_iframe_sandbox.asp

Like this?

a = [ "a", "b", "c", "d", "e" ]
a[2] +  a[0] + a[1]    #=> "cab"
a[6]                   #=> nil
a[1, 2]                #=> [ "b", "c" ]
a[1..3]                #=> [ "b", "c", "d" ]
a[4..7]                #=> [ "e" ]
a[6..10]               #=> nil
a[-3, 3]               #=> [ "c", "d", "e" ]
# special cases
a[5]                   #=> nil
a[5, 1]                #=> []
a[5..10]               #=> []

or like this?

a = [ "a", "b", "c" ]
a.index("b")   #=> 1
a.index("z")   #=> nil

If you are running Python <2.7, you need optparse, which as the doc explains will create an interface to the command line arguments that are called when your application is run.

However, in Python =2.7, optparse has been deprecated, and was replaced with the argparse as shown above. A quick example from the docs...

The following code is a Python program that takes a list of integers and produces either the sum or the max:

import argparse

parser = argparse.ArgumentParser(description='Process some integers.')
parser.add_argument('integers', metavar='N', type=int, nargs='+',
                   help='an integer for the accumulator')
parser.add_argument('--sum', dest='accumulate', action='store_const',
                   const=sum, default=max,
                   help='sum the integers (default: find the max)')

args = parser.parse_args()
print args.accumulate(args.integers)

The module not found likely means the packages aren't installed.

Debian has decided that distutils is not a core python package, so it is not included in the last versions of debian and debian-based OSes. You should be able to do

sudo apt-get install python3-distutils
sudo apt-get install python3-apt

You can edit /etc/paths. Here is mine:

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

Then add a symlink for the python version. In my case

$ cd /usr/local/bin
$ ln -s python3 python

The TableModel behind the JTable handles all of the data behind the table. In order to add and remove rows from a table, you need to use a DefaultTableModel

To create the table with this model:

JTable table = new JTable(new DefaultTableModel(new Object[]{"Column1", "Column2"}));

To add a row:

DefaultTableModel model = (DefaultTableModel) table.getModel();
model.addRow(new Object[]{"Column 1", "Column 2", "Column 3"});

You can also remove rows with this method.

Full details on the DefaultTableModel can be found here

SELECT *
FROM BOOKING_SESSION
WHERE TO_CHAR(T_SESSION_DATETIME, 'DD-MM-YYYY') ='20-03-2012';

You can't put a CLOB in the WHERE clause. From the documentation:

Large objects (LOBs) are not supported in comparison conditions. However, you can use PL/SQL programs for comparisons on CLOB data.

If your values are always less than 4k, you can use:

UPDATE IMS_TEST 
   SET TEST_Category           = 'just testing'  
 WHERE to_char(TEST_SCRIPT)    = 'something'
   AND ID                      = '10000239';

It is strange to search by a CLOB anyways.. could you not just search by the ID column?

I realize this is a belated answer, but looking through developer.android.com, it seems that the Toggle button would be ideal for your situation.

http://developer.android.com/guide/topics/ui/controls/togglebutton.html

And of course you can still use the other suggestions for having a background drawable to get a custom look you want.

<ToggleButton 
    android:id="@+id/togglebutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/custom_button_background"
    android:textOn="On"
    android:textOff="Off"
    />

Now if you want to go with your final edit and have a "halo" effect around your buttons, you can use another custom selector to do just that.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" > <!-- selected -->
        <shape>
            <solid
                android:color="@android:color/white" />
            <stroke
                android:width="3px"
                android:color="@android:color/holo_blue_bright" />
            <corners
                android:radius="5dp" />

If you use sufficiently big list not in b clause will do a linear search for each of the item in a. Why not use set? Set takes iterable as parameter to create a new set object.

>>> a = ["a", "b", "c", "d", "e"]
>>> b = ["c", "d", "f", "g"]
>>> set(a).intersection(set(b))
{'c', 'd'}

You want  win.Sleep(milliseconds), methinks.

Yeah, you definitely don't want to do a busy-wait like you describe.

SELECT word, COUNT(*) FROM words GROUP by word HAVING COUNT(*) > 1

All in all, to save symbols that require 4 bytes you need to update characher-set and collation for utf8mb4:

1. database table/column: alter table <some_table> convert to character set utf8mb4 collate utf8mb4_unicode_ci
2. database server connection (see)

On my development enviromnt for #2 I prefer to set parameters on command line when starting the server: mysqld --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

btw, pay attention to Connector/J behavior with SET NAMES 'utf8mb4':

Do not issue the query set names with Connector/J, as the driver will not detect that the character set has changed, and will continue to use the character set detected during the initial connection setup.

And avoid setting characterEncoding parameter in connection url as it will override configured server encoding:

To override the automatically detected encoding on the client side, use the characterEncoding property in the URL used to connect to the server.

Using a Neuraxle pipeline step:

1. Set up your example

import numpy as np
a = np.array([1,0,3])
b = np.array([[0,1,0,0], [1,0,0,0], [0,0,0,1]])

2. Do the actual conversion

from neuraxle.steps.numpy import OneHotEncoder
encoder = OneHotEncoder(nb_columns=4)
b_pred = encoder.transform(a)

3. Assert it works

assert b_pred == b
