@Tomas Petricek as you mentioned

A weaker invariant that is also true is that i >= 0 && i < 10 (because this is the continuation condition!)"

How it's a loop invariant?

I hope I am not wrong, as far as I understand^[1], Loop invariant will be true at the beginning of the loop (Initialization), it will be true before and after each iteration (Maintenance) and it will also be true after the termination of the loop (Termination). But after the last iteration i becomes 10. So, the condition i >= 0 && i < 10 becomes false and terminates the loop. It violates the third property (Termination) of loop invariant.

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

This is from an interview with Gosling and others, about simplicity:

Gosling: For me as a language designer, which I don't really count myself as these days, what "simple" really ended up meaning was could I expect J. Random Developer to hold the spec in his head. That definition says that, for instance, Java isn't -- and in fact a lot of these languages end up with a lot of corner cases, things that nobody really understands. Quiz any C developer about unsigned, and pretty soon you discover that almost no C developers actually understand what goes on with unsigned, what unsigned arithmetic is. Things like that made C complex. The language part of Java is, I think, pretty simple. The libraries you have to look up.

In Java, Regex constructor has

Regex(String pattern, RegexOption option)

So to ignore cases, use

option = RegexOption.IGNORE_CASE

Tensorflow 2.0 Compatible Answer: In Tensorflow Version >= 2.0, the command for Initializing all the Variables if we use Graph Mode, to fix the FailedPreconditionError is shown below:

tf.compat.v1.global_variables_initializer

This is just a shortcut for variables_initializer(global_variables())

It returns an Op that initializes global variables in the graph.

If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:

CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();

it should be slightly faster since it doesn't need to parse an input format.

I got the same error with something like:

Set rs = dbs.OpenRecordset _
( _
  "SELECT Field1, Field2, FieldN " _
  & "FROM Query1 " _
  & "WHERE Query2.Field1 = """ & Value1 & """;" _
, dbOpenSnapshot _
)

I fixed the error by replacing "Query1" with "Query2"

You can manually create the subplots with matplotlib, and then plot the dataframes on a specific subplot using the ax keyword. For example for 4 subplots (2x2):

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=2, ncols=2)

df1.plot(ax=axes[0,0])
df2.plot(ax=axes[0,1])
...

Here axes is an array which holds the different subplot axes, and you can access one just by indexing axes.
If you want a shared x-axis, then you can provide sharex=True to plt.subplots.

The code below will produce this plot:

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
import numpy as np

CorrMtx(df, dropDuplicates = False)

I put this together after it was announced that the outstanding seaborn corrplot was to be deprecated. The snippet above makes a resembling correlation plot based on seaborn heatmap. You can also specify the color range and select whether or not to drop duplicate correlations. Notice that I've used the same numbers as you, but that I've put them in a pandas dataframe. Regarding the choice of colors you can have a look at the documents for sns.diverging_palette. You asked for blue, but that falls out of this particular range of the color scale with your sample data. For both observations of 0.95173379, try changing to -0.95173379 and you'll get this:

That’s a typo. You’ve accidently set user.mail with no e. Fix it by setting user.email in the global configuration with

git config --global user.email "[email protected]"

Why not a/b/(c|d|e)? I just tried with Saxon XML library (wrapped up nicely with some Clojure goodness), and it seems to work. abc.xml is the doc described by OP.

(require '[saxon :as xml])
(def abc-doc (xml/compile-xml (slurp "abc.xml")))
(xml/query "a/b/(c|d|e)" abc-doc)

Updated Feb 2018: OpenBrace Limited has closed down, and its ObMimic product is no longer supported.

Here's another alternative, using OpenBrace's ObMimic library of Servlet API test-doubles (disclosure: I'm its developer).

            response.getMimicState().getBodyContentAsString());

    }

}

Notes:

• Each "mimic" has a "mimicState" object for its logical state. This provides a clear distinction between the Servlet API methods and the configuration and inspection of the mimic's internal state.

• You might be surprised that the check of Content-Type includes "charset=ISO-8859-1". However, for the given "doPost" code this is as per the Servlet API Javadoc, and the HttpServletResponse's own getContentType method, and the actual Content-Type header produced on e.g. Glassfish 3. You might not realise this if using normal mock objects and your own expectations of the API's behaviour. In this case it probably doesn't matter, but in more complex cases this is the sort of unanticipated API behaviour that can make a bit of a mockery of mocks!

• I've used response.getMimicState().getContentType() as the simplest way to check Content-Type and illustrate the above point, but you could indeed check for "text/html" on its own if you wanted (using response.getMimicState().getContentTypeMimeType()). Checking the Content-Type header the same way as for the Cache-Control header also works.

• For this example the response content is checked as character data (with this using the Writer's encoding). We could also check that the response's Writer was used rather than its OutputStream (using response.getMimicState().isWritingCharacterContent()), but I've taken it that we're only concerned with the resulting output, and don't care what API calls produced it (though that could be checked too...). It's also possible to retrieve the response's body content as bytes, examine the detailed state of the Writer/OutputStream etc.

There are full details of ObMimic and a free download at the OpenBrace website. Or you can contact me if you have any questions (contact details are on the website).

While SimpleDateFormat will indeed work for your needs, additionally you might want to check out Joda Time, which is apparently the basis for the redone Date library in Java 7. While I haven't used it a lot, I've heard nothing but good things about it and if your manipulating dates extensively in your projects it would probably be worth looking into.

I am quite sure that Xcode wants us to be logged in with our "normal" account to the App Store app when it tries to upload an app to the Mac App Store (MAS) via the Organizer window.

Usually, we developers all test our apps using our MAS test account. This seems to switch the logged App Store user, too. For me, this always works fine:

1. Log in to the App Store app with your normal account.
2. Retry the upload via the Xcode Organizer. Should then work like expected.

I had the same problems and it seems that they removed the destroy command from the CLI and you need to do it manually by deleting or renaming the according folders/files and imports, which is really a laborious task.

My answer is based on comment uniqid user comment but it uses openssl_random_pseudo_bytes function to generate random string instead of reading from /dev/urandom

function guid()
{
    $randomString = openssl_random_pseudo_bytes(16);
    $time_low = bin2hex(substr($randomString, 0, 4));
    $time_mid = bin2hex(substr($randomString, 4, 2));
    $time_hi_and_version = bin2hex(substr($randomString, 6, 2));
    $clock_seq_hi_and_reserved = bin2hex(substr($randomString, 8, 2));
    $node = bin2hex(substr($randomString, 10, 6));

    /**
     * Set the four most significant bits (bits 12 through 15) of the

     * @see http://tools.ietf.org/html/rfc4122#section-4.1.3
    */
    $time_hi_and_version = hexdec($time_hi_and_version);
    $time_hi_and_version = $time_hi_and_version >> 4;
    $time_hi_and_version = $time_hi_and_version | 0x4000;

    /**
     * Set the two most significant bits (bits 6 and 7) of the

     */
    $clock_seq_hi_and_reserved = hexdec($clock_seq_hi_and_reserved);
    $clock_seq_hi_and_reserved = $clock_seq_hi_and_reserved >> 2;
    $clock_seq_hi_and_reserved = $clock_seq_hi_and_reserved | 0x8000;

    return sprintf('%08s-%04s-%04x-%04x-%012s', $time_low, $time_mid, $time_hi_and_version, $clock_seq_hi_and_reserved, $node);
} // guid

Just use

int listCount = data.size();

That tells you how many lists there are (assuming none are null). If you want to find out how many strings there are, you'll need to iterate:

int total = 0;
for (List<String> sublist : data) {
    // TODO: Null checking
    total += sublist.size();
}
// total is now the total number of strings

basicaly 2 blocks of code that do the same thing. maybe it's a bit weird example but it proves the point. SQL Server 2005:

SELECT * INTO #temp FROM master..spt_values
DECLARE @startTime DATETIME

BEGIN TRAN 

SELECT @startTime = GETDATE()
UPDATE #temp
SET number = 0
select DATEDIFF(ms, @startTime, GETDATE())

ROLLBACK 

BEGIN TRAN 
DECLARE @name VARCHAR

DECLARE tempCursor CURSOR
    FOR SELECT name FROM #temp

OPEN tempCursor

FETCH NEXT FROM tempCursor 
INTO @name

SELECT @startTime = GETDATE()
WHILE @@FETCH_STATUS = 0
BEGIN

    UPDATE #temp SET number = 0 WHERE NAME = @name
    FETCH NEXT FROM tempCursor 
    INTO @name

END 
select DATEDIFF(ms, @startTime, GETDATE())
CLOSE tempCursor
DEALLOCATE tempCursor

ROLLBACK 
DROP TABLE #temp

the single update takes 156 ms while the cursor takes 2016 ms.

You can't do it with pure html/javascript. This is because you have a seperate connection to the webserver to retrieve a separate file (the image) and a normal webserver will serve the file with content headers set so that the browser reading the content type will decide that the type can be handled internally.

The way to force the browser not to handle the file internally is to change the headers (content-disposition prefereably, or content-type) so the browser will not try to handle the file internally. You can either do this by writing a script on the webserver that dynamically sets the headers (i.e. download.php) or by configuring the webserver to return different headers for the file you want to download. You can do this on a per-directory basis on the webserver, which would allow you to get away without writing any php or javascript - simply have all your download images in that one location.

It should be noted as well that this will of course only find all those subclasses that exist on your current classpath. Presumably this is OK for what you are currently looking at, and chances are you did consider this, but if you have at any point released a non-final class into the wild (for varying levels of "wild") then it is entirely feasible that someone else has written their own subclass that you will not know about.

Thus if you happened to be wanting to see all subclasses because you want to make a change and are going to see how it affects subclasses' behaviour - then bear in mind the subclasses that you can't see. Ideally all of your non-private methods, and the class itself should be well-documented; make changes according to this documentation without changing the semantics of methods/non-private fields and your changes should be backwards-compatible, for any subclass that followed your definition of the superclass at least.

In Apple's Developer's portal, add a new certificate, and when asked "What type of certificate do you need?" choose "WorldWide developer relations certificate". Generate the new certificate, download and install. The moment you do that, you will no longer see the message you have described.

Edit:
The certificate can be downloaded from the following page: https://www.apple.com/certificateauthority/ You can choose one of the following two certificates: "WWDR Certificate (Expiring 02/07/23)" or "WWDR Certificate (Expiring 02/14/16)"

If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer.

function myFn() {console.log('idle');}

var myTimer = setInterval(myFn, 4000);

// Then, later at some future time, 
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);

You could also use a little timer object that offers a reset feature:

function Timer(fn, t) {
    var timerObj = setInterval(fn, t);

    this.stop = function() {
        if (timerObj) {
            clearInterval(timerObj);
            timerObj = null;
        }
        return this;
    }

    // start timer using current settings (if it's not already running)
    this.start = function() {
        if (!timerObj) {
            this.stop();
            timerObj = setInterval(fn, t);
        }
        return this;
    }

    // start with new or original interval, stop current interval
    this.reset = function(newT = t) {
        t = newT;
        return this.stop().start();
    }
}

Usage:

var timer = new Timer(function() {
    // your function here
}, 5000);


// switch interval to 10 seconds
timer.reset(10000);

// stop the timer
timer.stop();

// start the timer
timer.start();

You are probably using the HotSpot JVM (originally by Sun Microsystems, later bought by Oracle, part of the OpenJDK), which performs a lot of optimization. To get the stack traces back, you need to pass the option -XX:-OmitStackTraceInFastThrow to the JVM.

The optimization is that when an exception (typically a NullPointerException) occurs for the first time, the full stack trace is printed and the JVM remembers the stack trace (or maybe just the location of the code). When that exception occurs often enough, the stack trace is not printed anymore, both to achieve better performance and not to flood the log with identical stack traces.

To see how this is implemented in the HotSpot JVM, grab a copy of it and search for the global variable OmitStackTraceInFastThrow. Last time I looked at the code (in 2019), it was in the file graphKit.cpp.

Just use the formula

=A8*60*24

I tried the following solution with the UITextArea and I expect this will work with UIButton as well.

First of all import this in your .m file -

#import <QuartzCore/QuartzCore.h>

and then in your loadView method add following lines

    yourButton.layer.cornerRadius = 10; // this value vary as per your desire
    yourButton.clipsToBounds = YES;

Your regex says the following:

/^         - if the line starts with
(          - start a capture group
Clinton|   - "Clinton" 
|          - or
[^Bush]    - Any single character except "B", "u", "s" or "h"
|          - or
Reagan)   - "Reagan". End capture group.
/i         - Make matches case-insensitive 

So, in other words, your middle part of the regex is screwing you up. As it is a "catch-all" kind of group, it will allow any line that does not begin with any of the upper or lower case letters in "Bush". For example, these lines would match your regex:

Our president, George Bush
In the news today, pigs can fly
012-3123 33

You either make a negative look-ahead, as suggested earlier, or you simply make two regexes:

if( ($string =~ m/^(Clinton|Reagan)/i) and
    ($string !~ m/^Bush/i) ) {
   print "$string\n";
}

As mirod has pointed out in the comments, the second check is quite unnecessary when using the caret (^) to match only beginning of lines, as lines that begin with "Clinton" or "Reagan" could never begin with "Bush".

However, it would be valid without the carets.

Wildcard works for me also, but I'd like to give a side note for those using directory variables. Always use slash for folder tree (not backslash), otherwise it will fail:

BASEDIR = ../..
SRCDIR = $(BASEDIR)/src
INSTALLDIR = $(BASEDIR)/lib

MODULES = $(wildcard $(SRCDIR)/*.cpp)
OBJS = $(wildcard *.o)

Here is a safe and reusable function for adding script to head section if its not already exist there.

see working example here: Example

<!DOCTYPE html>
<html>
  <head>
    <base href="/"/>
    <style>
    </style>
  </head>
  <body>
    <input type="button" id="" style='width:250px;height:50px;font-size:1.5em;' value="Add Script" onClick="addScript('myscript')"/>
    <script>
      function addScript(filename)
      {
        // house-keeping: if script is allready exist do nothing
        if(document.getElementsByTagName('head')[0].innerHTML.toString().includes(filename + ".js"))
        {
          alert("script is allready exist in head tag!")
        }
        else
        {
          // add the script
          loadScript('/',filename + ".js");
        }
      }
      function loadScript(baseurl,filename)
      {
        var node = document.createElement('script');
        node.src = baseurl + filename;
        document.getElementsByTagName('head')[0].appendChild(node);
        alert("script added");
      }
    </script>
  </body>
</html>

In a shell, & is a special character, advising the shell to start everything up to the & as a process in the background. To avoid this behavior, you can put the URL in quotes. See the youtube-dl FAQ for more information.

Also beware of -citk. With the exception of -i, these options make little sense. See the youtube-dl FAQ for more information. Even -f mp4 looks very strange.

So what you want is:

youtube-dl -i -f mp4 --yes-playlist 'https://www.youtube.com/watch?v=7Vy8970q0Xc&list=PLwJ2VKmefmxpUJEGB1ff6yUZ5Zd7Gegn2'

Alternatively, you can just use the playlist ID:

youtube-dl -i PLwJ2VKmefmxpUJEGB1ff6yUZ5Zd7Gegn2

I also experienced that for example:

This code doesnt work and get the intended block error.

class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()

def __unicode__(self):
return self.title

However, when i press tab before typing return self.title statement, the code works.

class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()

def __unicode__(self):
    return self.title

Hope, this will help others.

Then NumPy sum function takes an optional axis argument that specifies along which axis you would like the sum performed:

>>> a = numpy.arange(12).reshape(4,3)
>>> a.sum(0)
array([18, 22, 26])

Or, equivalently:

>>> numpy.sum(a, 0)
array([18, 22, 26])

Posting this as an equally viable alternative to @Binil Thomas's answer - tried to add it as a comment, but was not convinced of the readability of it all.

int index = 0;

for (Object key : map.keySet()) {
   Object value = map.get(key);
   ++index;
}

Probably doesn't help the original question poster since this is the literal situation they were trying to avoid, but may aid others searching for an easy answer.

A rather inexpensive option would be to use the ipdata.co API, it's free upto 1500 requests a day.

This answer uses a 'test' API Key that is very limited and only meant for testing a few calls. Signup for your own Free API Key and get up to 1500 requests daily for development.

I also faced this problem, at first I just wanted to specialize the responses in my http handler. My first approach was creating a package that copies the information of a struct to another struct and then marshal that second struct. I did that package using reflection, so, never liked that approach and also I wasn't dynamically.

So I decided to modify the encoding/json package to do this. The functions Marshal, MarshalIndent and (Encoder) Encode additionally receives a

type F map[string]F

I wanted to simulate a JSON of the fields that are needed to marshal, so it only marshals the fields that are in the map.

Is the Canvas crucial in your window? If not, try removing it and keep the Grid as the main panel. Canvas has no size unless specified, while a Grid normally takes up all available space. Inside the Canvas, the Grid will have no available space.

Give the submit buttons for both forms different names and use PHP to check which button has submitted data.

Form one button - btn1 Form two button -btn2

PHP Code:

if($_POST['btn1']){
    //Login
}elseif($_POST['btn2']){
    //Register
}

What about performance?

1. Always debounce events to reduce calculations
2. Use scope.applyAsync to reduce overall digest cycles count

function debounce(func, wait) {
    var timeout;
    return function () {
        var context = this, args = arguments;
        var later = function () {
            timeout = null;
            func.apply(context, args);
        };

        if (!timeout) func.apply(context, args);
        clearTimeout(timeout);
        timeout = setTimeout(later, wait);
    };
}

angular.module('app.layout')
  .directive('classScroll', function ($window) {    
    return {
        restrict: 'A',
        link: function (scope, element) {    
            function toggle() {
                angular.element(element)
                  .toggleClass('class-scroll--scrolled', 
                    window.pageYOffset > 0);
                scope.$applyAsync();
            }    
            angular.element($window)
              .on('scroll', debounce(toggle, 50));

            toggle();
        }
    };
});

3. If you don't need to trigger watchers/digests at all then use compile

.directive('classScroll', function ($window, utils) {
    return {
        restrict: 'A',
        compile: function (element, attributes) {
            function toggle() {
                angular.element(element)
                  .toggleClass(attributes.classScroll,
                    window.pageYOffset > 0);
            }

            angular.element($window)
              .on('scroll', utils.debounce(toggle, 50));
            toggle();
        }
    };
  });

And you can use it like <header class-scroll="header--scrolled">

OPTIONS method returns info about API (methods/content type)

HEAD method returns info about resource (version/length/type)

Server response

OPTIONS

HTTP/1.1 200 OK
Allow: GET,HEAD,POST,OPTIONS,TRACE
Content-Type: text/html; charset=UTF-8
Date: Wed, 08 May 2013 10:24:43 GMT

HEAD

HTTP/1.1 200 OK
Accept-Ranges: bytes

• OPTIONS Identifying which HTTP methods a resource supports, e.g. can we DELETE it or update it via a PUT?
• HEAD Checking whether a resource has changed. This is useful when maintaining a cached version of a resource
• HEAD Retrieving metadata about the resource, e.g. its media type or its size, before making a possibly costly retrieval
• HEAD, OPTIONS Testing whether a resource exists and is accessible. For example, validating user-submitted links in an application

Here is nice and concise article about how HEAD and OPTIONS fit into RESTful architecture.

With formatting

require 'json'
tempHash = {
    "key_a" => "val_a",
    "key_b" => "val_b"
}
File.open("public/temp.json","w") do |f|
  f.write(JSON.pretty_generate(tempHash))
end

Output

{
    "key_a":"val_a",
    "key_b":"val_b"
}

If you want to copy something from one directory into the current directory, do this:

cp dir1/* .

This assumes you're not trying to copy hidden files.

As a practical matter, the advantage of synchronized methods over synchronized blocks is that they are more idiot-resistant; because you can't choose an arbitrary object to lock on, you can't misuse the synchronized method syntax to do stupid things like locking on a string literal or locking on the contents of a mutable field that gets changed out from under the threads.

On the other hand, with synchronized methods you can't protect the lock from getting acquired by any thread that can get a reference to the object.

So using synchronized as a modifier on methods is better at protecting your cow-orkers from hurting themselves, while using synchronized blocks in conjunction with private final lock objects is better at protecting your own code from the cow-orkers.

Being impatient, I created a new App Pool with the same settings and used that.

After looking around, the solution was to remove the NDK designation from my preferences.

Android Studio ? Preferences ? System Settings ? Android SDK ? SDK Tools ? Unselect NDK ? Apply button.

Project and Gradle compiled fine after that and I was able to move on with my project work.

As far as why this is happening, I do not know but for more info on NDK check out:

This is bad style, but I'll assume you have a good reason for doing something similar.

<html>
<body>
    <input type="text" id="userInput">give me input</input>
    <button id="submitter">Submit</button>
    <div id="output"></div>
    <script>
        var didClickIt = false;
        document.getElementById("submitter").addEventListener("click",function(){
            // same as onclick, keeps the JS and HTML separate
            didClickIt = true;
        });

        setInterval(function(){
            // this is the closest you get to an infinite loop in JavaScript
            if( didClickIt ) {
                didClickIt = false;
                // document.write causes silly problems, do this instead (or better yet, use a library like jQuery to do this stuff for you)
                var o=document.getElementById("output"),v=document.getElementById("userInput").value;
                if(o.textContent!==undefined){
                    o.textContent=v;
                }else{
                    o.innerText=v;
                }
            }
        },500);
    </script>
</body>
</html>

You need to add uppercase L at the end like so

long i = 12345678910L;

Same goes true for float with 3.0f

Which should answer both of your questions

A great way to import the RecyclerView into your project is the RecyclerViewLib. This is an open source library which pulled out the RecyclerView to make it safe and easy implement. You can read the author's blog post here.

Add the following line as a gradle dependency in your code:

dependencies {
    compile 'com.twotoasters.RecyclerViewLib:library:1.0.+@aar'
}

More info for how to bring in gradle dependencies:

Bosnia you're right about that being annoying. Gradle may seem complicated but it is extremely powerful and flexible. Everything is done in the language groovy and learning the gradle system is learning another language just so you can build your Android app. It hurts now, but in the long run you'll love it.

Check out the build.gradle for the same app. https://github.com/twotoasters/RecyclerViewLib/blob/master/sample/build.gradle Where it does the following is where it brings the lib into the module (aka the sample app)

compile (project (':library')) {
    exclude group: 'com.android.support', module: 'support-v4' 
}

Pay attention to the location of this file. This is not the top level build.gradle

Because the lib source is in the same project it is able to do this with the simple ':library'. The exclude tells the lib to use the sample app's support v4. That isn't necessary but is a good idea. You don't have or want to have the lib's source in your project, so you have to point to the internet for it. In your module's/app's build.gradle you would put that line from the beginning of this answer in the same location. Or, if following the samples example, you could replace ':library' with ' com.twotoasters.RecyclerViewLib:library:1.0.+@aar ' and use the excludes.

I was looking for a resolution to this issue in Windows, and it seems to be that if you don't have the environments vars ok, you need to put the complete directory. For eg. with a file in the same directory than PHP:

F:\myfolder\php\php.exe -f F:\myfolder\php\script.php

We managed to solve the error under Windows Server 2012 by:

1. Removing from "Remove Roles and Features Wizard" .NET Framework 4.5 Features/ASP.NET 4.5 and all its dependent features
2. Re-installing the removed features.

It seems the order of installation is the cause.

Also, make sure you have HTTP Activation installed under WCF Services.

Simply subtract them:

SELECT ('2015-01-12'::date - '2015-01-01'::date) AS days;

The result:

 days
------
   11

You can simply make use of the DateTime class , OOP Style.

<?php
$date = new DateTime('1:00:00');
$date->add(new DateInterval('PT10H'));
echo $date->format('H:i:s a'); //"prints" 11:00:00 a.m

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

In the manifest file Change:

    android:theme="@style/AppTheme" >
    android:theme="@style/Theme.AppCompat.NoActionBar"

tl;dr

Yes, you can... If a then a, else if b then if c then c(b), else b, else null

a ? a : (b ? (c ? c(b) : b) : null)

a
  ? a
  : b
      ? c
        ? c(b)
        : b
      : null

Ternary operator ?: used as inline if-else is right associative. In short this means that the rightmost ? gets fed first and it takes exactly one closest operand on the left and two, with a :, on the right.

Practically speaking, consider the following statement (same as above):

a ? a : b ? c ? c(b) : b : null

The rightmost ? gets fed first, so find it and its surrounding three arguments and consecutively expand to the left to another ?.

   a ? a : b ? c ? c(b) : b : null
                 ^                  <---- RTL
1.            |1-?-2----:-3|
             ^ <-
2.        |1-?|--2---------|:-3---|
     ^ <-
3.|1-?-2-:|--3--------------------|

result: a ? a : (b ? (c ? c(b) : b) : null)

This is how computers read it:

1. Term a is read.
   Node: a
2. Nonterminal ? is read.
   Node: a ?
3. Term a is read.
   Node: a ? a
4. Nonterminal : is read.
   Node: a ? a :
5. Term b is read.
   Node: a ? a : b
6. Nonterminal ? is read, triggering the right-associativity rule. Associativity decides:
   node: a ? a : (b ?
7. Term c is read.
   Node: a ? a : (b ? c
8. Nonterminal ? is read, re-applying the right-associativity rule.
   Node: a ? a : (b ? (c ?
9. Term c(b) is read.
   Node: a ? a : (b ? (c ? c(b)
10. Nonterminal : is read.
    Node: a ? a : (b ? (c ? c(b) :
11. Term b is read.
    Node: a ? a : (b ? (c ? c(b) : b
12. Nonterminal : is read. The ternary operator ?: from previous scope is satisfied and the scope is closed.
    Node: a ? a : (b ? (c ? c(b) : b) :
13. Term null is read.
    Node: a ? a : (b ? (c ? c(b) : b) : null
14. No tokens to read. Close remaining open parenthesis.
    #Result is: a ? a : (b ? (c ? c(b) : b) : null)

Better readability

The ugly oneliner from above could (and should) be rewritten for readability as:
(Note that the indentation does not implicitly define correct closures as brackets () do.)

a
  ? a
  : b
      ? c
        ? c(b)
        : b
      : null

for example

return a + some_lengthy_variable_name > another_variable
        ? "yep"
        : "nop"

You should use small caps "or" and "and" instead of OR and AND.

And beware also the spaces/tabs between keywords and arguments (you need at least two spaces).

Here is a code sample with your three keywords working fine:

Here is the file ts.txt:

  *** test cases ***
  mytest
    ${color} =  set variable  Red
    Run Keyword If  '${color}' == 'Red'  log to console  \nexecuted with single condition
    Run Keyword If  '${color}' == 'Red' or '${color}' == 'Blue' or '${color}' == 'Pink'  log to console  \nexecuted with multiple or

    ${color} =  set variable  Blue
    ${Size} =  set variable  Small
    ${Simple} =  set variable  Simple
    ${Design} =  set variable  Simple
    Run Keyword If  '${color}' == 'Blue' and '${Size}' == 'Small' and '${Design}' != '${Simple}'  log to console  \nexecuted with multiple and

    ${Size} =  set variable  XL
    ${Design} =  set variable  Complicated
    Run Keyword Unless  '${color}' == 'Black' or '${Size}' == 'Small' or '${Design}' == 'Simple'  log to console  \nexecuted with unless and multiple or

and here is what I get when I execute it:

$ pybot ts.txt

Suppose a 9800GT GPU:

• it has 14 multiprocessors (SM)
• each SM has 8 thread-processors (AKA stream-processors, SP or cores)
• allows up to 512 threads per block
• warpsize is 32 (which means each of the 14x8=112 thread-processors can schedule up to 32 threads)

https://www.tutorialspoint.com/cuda/cuda_threads.htm

A block cannot have more active threads than 512 therefore __syncthreads can only synchronize limited number of threads. i.e. If you execute the following with 600 threads:

func1();
__syncthreads();
func2();
__syncthreads();

then the kernel must run twice and the order of execution will be:

1. func1 is executed for the first 512 threads
2. func2 is executed for the first 512 threads
3. func1 is executed for the remaining threads
4. func2 is executed for the remaining threads

Note:

The main point is __syncthreads is a block-wide operation and it does not synchronize all threads.

I'm not sure about the exact number of threads that __syncthreads can synchronize, since you can create a block with more than 512 threads and let the warp handle the scheduling. To my understanding it's more accurate to say: func1 is executed at least for the first 512 threads.

Before I edited this answer (back in 2010) I measured 14x8x32 threads were synchronized using __syncthreads.

I would greatly appreciate if someone test this again for a more accurate piece of information.

The problem is that when you are doing additions and multiplications of numbers all with two decimal places, you expect there will be no rounding errors, but remember the internal representation of double is in base 2, not in base 10 ! So a number like 0.1 in base 10 may be in base 2 : 0.101010101010110011... with an infinite number of decimals (the value stored in the double will be a number N with :

 0.1-Math.Pow(2,-64) < N < 0.1+Math.Pow(2,-64) 

As a consequence an operation like 12.3 + 0.1 may be not the same exact 64 bits double value as 12.4 (or 12.456 * 10 may be not the same as 124.56) because of rounding errors. For example if you store in a Database the result of 12.3 +0.1 into a table/column field of type double precision number and then SELECT WHERE xx=12.4 you may realize that you stored a number that is not exactly 12.4 and the Sql select will not return the record; So if you cannot use the decimal datatype (which has internal representation in base 10) and must use the 'double' datatype, you have to do some normalization after each addition or multiplication :

double freqMHz= freqkHz.MulRound(0.001); // freqkHz*0.001
double amountEuro= amountEuro.AddRound(delta); // amountEuro+delta


    public static double AddRound(this double d,double val)
    {
        return double.Parse(string.Format("{0:g14}", d+val));
    }
    public static double MulRound(this double d,double val)
    {
        return double.Parse(string.Format("{0:g14}", d*val));
    }

Simplest Solution:

Tools->Kotlin->Configure Kotin in Project

Upvote if found Usefull.

#include ...

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QGraphicsScene scene;
    QGraphicsView view(&scene);
    QGraphicsPixmapItem item(QPixmap("c:\\test.png"));
    scene.addItem(&item);
    view.show();
    return a.exec();
}

This should work. :) List of supported formats can be found here

Update:

As mentioned below, not all implementations support this callback (i.e. platforms like iOS). In this case, as the docs say, you can set the validator explicitly:

handler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator;

This works too for .NET Core 2.2, 3.0 and 3.1

Old answer, with more control but may throw PlatformNotSupportedException:

You can override SSL cert check on a HTTP call with the a anonymous callback function like this

using (var httpClientHandler = new HttpClientHandler())
{
   httpClientHandler.ServerCertificateCustomValidationCallback = (message, cert, chain, errors) => { return true; };
   using (var client = new HttpClient(httpClientHandler))
   {
       // Make your request...
   }
}

Additionally, I suggest to use a factory pattern for HttpClient because it is a shared object that might no be disposed immediately and therefore connections will stay open.

The below packages are also helps you,

yum install gcc glibc glibc-common gd gd-devel -y

namedtuple is a factory function for making a tuple class. With that class we can create tuples that are callable by name also.

import collections

#Create a namedtuple class with names "a" "b" "c"
Row = collections.namedtuple("Row", ["a", "b", "c"])   

row = Row(a=1,b=2,c=3) #Make a namedtuple from the Row class we created

print row    #Prints: Row(a=1, b=2, c=3)
print row.a  #Prints: 1
print row[0] #Prints: 1

row = Row._make([2, 3, 4]) #Make a namedtuple from a list of values

print row   #Prints: Row(a=2, b=3, c=4)

Modify onClick() as follows:

@Override
public void onClick(View v) {
    if(v == btn) {
        canvas=sv.getHolder().lockCanvas();
        if(canvas!=null) {
            canvas.drawBitmap(bitmap, 100, 100, null);
            sv.getHolder().unlockCanvasAndPost(canvas);
        }
    } else if(v == btn1) {
        saveBitmapToInternalStorage(bitmap);
    }
}

There are several ways to enforce that btn must be pressed before btn1 so that the bitmap is painted before you attempt to save it.

I suggest that you initially disable btn1, and that you enable it when btn is clicked, like this:

if(v == btn) {
    ...
    btn1.setEnabled(true);
}

None of the above answers were complete for me. If your field is named field, so the selector should be the following one:

IFNULL(`field`,0) AS field

For example in a SELECT query:

SELECT IFNULL(`field`,0) AS field, `otherfield` FROM `mytable`

Hope this can help someone to not waste time.

points or lines comes handy if

• y2 is generated later, or
• the new data does not have the same x but still should go into the same coordinate system.

As your ys share the same x, you can also use matplot:

matplot (x, cbind (y1, y2), pch = 19)

(without the pch matplopt will plot the column numbers of the y matrix instead of dots).

I was facing a similar issue and below line fixed the issue for me.

    <dependency>
        <groupId>org.slf4j</groupId>

Edit: I realized that I was using spring boot and the version of the dependency was getting pulled from spring-boot-starter-parent.

Since JavaScript doesn't have function overload options object can be used instead. If there are one or two required arguments, it's better to keep them separate from the options object. Here is an example on how to use options object and populated values to default value in case if value was not passed in options object.

function optionsObjectTest(x, y, opts) {
    opts = opts || {}; // default to an empty options object

    var stringValue = opts.stringValue || "string default value";
    var boolValue = !!opts.boolValue; // coerces value to boolean with a double negation pattern
    var numericValue = opts.numericValue === undefined ? 123 : opts.numericValue;

    return "{x:" + x + ", y:" + y + ", stringValue:'" + stringValue + "', boolValue:" + boolValue + ", numericValue:" + numericValue + "}";

}

here is an example on how to use options object

I created a simple extension that gives you an unsorted Array as a property of Set in Swift 4.0.

extension Set {
    var array: [Element] {
        return Array(self)
    }
}

If you want a sorted array, you can either add an additional computed property, or modify the existing one to suit your needs.

To use this, just call

let array = set.array

SELECT DISTINCT groups.id, 
       (SELECT COUNT(*) FROM group_members
        WHERE member_id = groups.id) AS memberCount
FROM groups

First, always sudo nginx -t to verify your config files are good.

I ran into the same problem. The reason I had the issue was twofold. First, I had accidentally copied a log file into my site-enabled folder. I deleted the log file and made sure that all the files in sites-enabled were proper nginx site configs. I also noticed two of my virtual hosts were listening for the same domain. So I made sure that each of my virtual hosts had unique domain names.

sudo service nginx restart

Then it worked.

High-Level Design (HLD) involves decomposing a system into modules, and representing the interfaces & invocation relationships among modules. An HLD is referred to as software architecture.

LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.

Now, HLD and LLD are actually used in traditional Approach (Function-Oriented Software Design) whereas, in OOAD, the system is seen as a set of objects interacting with each other.

As per the above definitions, a high-level design document will usually include a high-level architecture diagram depicting the components, interfaces, and networks that need to be further specified or developed. The document may also depict or otherwise refer to work flows and/or data flows between component systems.

Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module. The LLD will contain - a detailed functional logic of the module in pseudo code - database tables with all elements including their type and size - all interface details with complete API references(both requests and responses) - all dependency issues - error message listings - complete inputs and outputs for a module.

public class MyObject implements Cloneable, Serializable{   

    @Override
    @SuppressWarnings(value = "unchecked")
    protected MyObject clone(){
        ObjectOutputStream oos = null;
        ObjectInputStream ois = null;
        try {
            ByteArrayOutputStream bOs = new ByteArrayOutputStream();
            oos = new ObjectOutputStream(bOs);
            oos.writeObject(this);
            ois = new ObjectInputStream(new ByteArrayInputStream(bOs.toByteArray()));
            return  (MyObject)ois.readObject();

        } catch (Exception e) {
            //Some seriouse error :< //
            return null;
        }finally {
            if (oos != null)
                try {
                    oos.close();
                } catch (IOException e) {

                }
            if (ois != null)
                try {

                } catch (IOException e) {

                }
        }
    }
}

Remember that

log(n!) = log(1) + log(2) + ... + log(n-1) + log(n)

You can get the upper bound by

log(1) + log(2) + ... + log(n) <= log(n) + log(n) + ... + log(n)
                                = n*log(n)

And you can get the lower bound by doing a similar thing after throwing away the first half of the sum:

log(1) + ... + log(n/2) + ... + log(n) >= log(n/2) + ... + log(n) 
                                       = log(n/2) + log(n/2+1) + ... + log(n-1) + log(n)
                                       >= log(n/2) + ... + log(n/2)
                                        = n/2 * log(n/2) 

Just run

docker restart $(docker ps -q)

Update

For Docker 1.13.1 use docker restart $(docker ps -a -q) as in answer lower.

$cmd would just replace the variable with it's value to be executed on command line. eval "$cmd" does variable expansion & command substitution before executing the resulting value on command line

The 2nd method is helpful when you wanna run commands that aren't flexible eg.
for i in {$a..$b}
format loop won't work because it doesn't allow variables.
In this case, a pipe to bash or eval is a workaround.

Tested on Mac OSX 10.6.8, Bash 3.2.48

Simple Solution Solution Works Given: If your HEAD commit is in sync with remote commit.

• Create one more branch in your local workspace, and keep it in sync with your remote branch.
• Cherry pick the HEAD commit from the branch (where git commit --amend) was performed onto the newly created branch.

The cherry-picked commit will only contain your latest changes, not the old changes. You can now just rename this commit.

Use the oninput event

<input type="text" oninput="myFunction();" />

Section 6.6 of The C Programming Language presents a simple dictionary (hashtable) data structure. I don't think a useful dictionary implementation could get any simpler than this. For your convenience, I reproduce the code here.

struct nlist { /* table entry: */
    struct nlist *next; /* next entry in chain */
    char *name; /* defined name */
    char *defn; /* replacement text */
};

#define HASHSIZE 101
static struct nlist *hashtab[HASHSIZE]; /* pointer table */

/* hash: form hash value for string s */
unsigned hash(char *s)
{
    unsigned hashval;
    for (hashval = 0; *s != '\0'; s++)
      hashval = *s + 31 * hashval;
    return hashval % HASHSIZE;
}

/* lookup: look for s in hashtab */
struct nlist *lookup(char *s)
{
    struct nlist *np;
    for (np = hashtab[hash(s)]; np != NULL; np = np->next)
        if (strcmp(s, np->name) == 0)
          return np; /* found */
    return NULL; /* not found */
}

char *strdup(char *);
/* install: put (name, defn) in hashtab */
struct nlist *install(char *name, char *defn)
{
    struct nlist *np;
    unsigned hashval;
    if ((np = lookup(name)) == NULL) { /* not found */
        np = (struct nlist *) malloc(sizeof(*np));
        if (np == NULL || (np->name = strdup(name)) == NULL)
          return NULL;
        hashval = hash(name);
        np->next = hashtab[hashval];
        hashtab[hashval] = np;
    } else /* already there */
        free((void *) np->defn); /*free previous defn */
    if ((np->defn = strdup(defn)) == NULL)
       return NULL;
    return np;
}

char *strdup(char *s) /* make a duplicate of s */
{
    char *p;
    p = (char *) malloc(strlen(s)+1); /* +1 for ’\0’ */
    if (p != NULL)
       strcpy(p, s);
    return p;
}

Note that if the hashes of two strings collide, it may lead to an O(n) lookup time. You can reduce the likelihood of collisions by increasing the value of HASHSIZE. For a complete discussion of the data structure, please consult the book.

I think a combination of xdg-open as described by shellholic and - if it fails - the solution to finding a browser using the which command as described here is probably the best solution.

Update 2020 with Visual Studio Community 2019 and Unity 2019.3:

1. Open Visual Studio Installer as Administrator, select to modify your current installation and add "Game development for Unity"

2. If you add a new c# script in Unity now, and open it (automatically) with Visual Studio, it is not described as "Miscellaneous" at the top of the window but with "Assembly-CSharp", and the autocomplete works.

public byte[] longToBytes(long x) {
    ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
    buffer.putLong(x);
    return buffer.array();
}

public long bytesToLong(byte[] bytes) {
    ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);
    buffer.put(bytes);
    buffer.flip();//need flip 
    return buffer.getLong();
}

Or wrapped in a class to avoid repeatedly creating ByteBuffers:

public class ByteUtils {
    private static ByteBuffer buffer = ByteBuffer.allocate(Long.BYTES);    

    public static byte[] longToBytes(long x) {
        buffer.putLong(0, x);
        return buffer.array();
    }

    public static long bytesToLong(byte[] bytes) {
        buffer.put(bytes, 0, bytes.length);
        buffer.flip();//need flip 
        return buffer.getLong();
    }
}

Since this is getting so popular, I just want to mention that I think you're better off using a library like Guava in the vast majority of cases. And if you have some strange opposition to libraries, you should probably consider this answer first for native java solutions. I think the main thing my answer really has going for it is that you don't have to worry about the endian-ness of the system yourself.

You cannot play two animations since the attribute can be defined only once. Rather why don't you include the second animation in the first and adjust the keyframes to get the timing right?

For add environment variable please add \ after bin like below

C:\Program Files\MongoDB\Server\3.2\bin\

Then try below code in command prompt to run mongo server from parent folder of data folder.

mongod -dbpath ./data

For my case I am unable to run mongo from command prompt(normal mode). You should run as administrator. It also works on git bash.

I was recently working with IPFS and worked this out. A curl example for IPFS to upload a file looks like this:

curl -i -H "Content-Type: multipart/form-data; boundary=CUSTOM" -d $'--CUSTOM\r\nContent-Type: multipart/octet-stream\r\nContent-Disposition: file; filename="test"\r\n\r\nHello World!\n--CUSTOM--' "http://localhost:5001/api/v0/add"

The basic idea is that each part (split by string in boundary with --) has it's own headers (Content-Type in the second part, for example.) The FormData object manages all this for you, so it's a better way to accomplish our goals.

This translates to fetch API like this:

const formData = new FormData()
formData.append('blob', new Blob(['Hello World!\n']), 'test')

fetch('http://localhost:5001/api/v0/add', {
  method: 'POST',

Note, that Dijkstra works even for negative weights, if the Graph has no negative cycles, i.e. cycles whose summed up weight is less than zero.

Of course one might ask, why in the example made by templatetypedef Dijkstra fails even though there are no negative cycles, infact not even cycles. That is because he is using another stop criterion, that holds the algorithm as soon as the target node is reached (or all nodes have been settled once, he did not specify that exactly). In a graph without negative weights this works fine.

If one is using the alternative stop criterion, which stops the algorithm when the priority-queue (heap) runs empty (this stop criterion was also used in the question), then dijkstra will find the correct distance even for graphs with negative weights but without negative cycles.

However, in this case, the asymptotic time bound of dijkstra for graphs without negative cycles is lost. This is because a previously settled node can be reinserted into the heap when a better distance is found due to negative weights. This property is called label correcting.

I modified "Jannich Brendle" version to 1000 instead 500. And list the result of euler12.bin, euler12.erl, p12dist.erl. Both erl codes use '+native' to compile.

Trying to access an undefined variable will throw you a ReferenceError.

A solution to this is to use typeof:

if (typeof window === "undefined") {
  console.log("Oops, `window` is not defined")
}

or a try catch:

try { window } catch (err) {
  console.log("Oops, `window` is not defined")
}

While typeof window is probably the cleanest of the two, the try catch can still be useful in some cases.

Try this (update, not after update)

CREATE TRIGGER [dbo].[xxx_update] ON [dbo].[MYTABLE]
    FOR UPDATE
    AS
    BEGIN

        UPDATE MYTABLE
        SET mytable.CHANGED_ON = GETDATE()
            ,CHANGED_BY = USER_NAME(USER_ID())
        FROM inserted
        WHERE MYTABLE.ID = inserted.ID

    END

Purely on the basis of inheritance, you would use an Abstract where you're defining clearly descendant, abstract relationships (i.e. animal->cat) and/or require inheritance of virtual or non-public properties, especially shared state (which Interfaces cannot support).

You should try and favour composition (via dependency injection) over inheritance where you can though, and note that Interfaces being contracts support unit-testing, separation of concerns and (language varying) multiple inheritance in a way Abstracts cannot.

This works for me:

var table = new DataTable();
table.Rows.Add();

First Program with comments

#include <stdio.h>

int main(){
    int *ptr;             //Create a pointer that points to random memory address

    *ptr = 20;            //Dereference that pointer, 
                          // and assign a value to random memory address.
                          //Depending on external (not inside your program) state
                          // this will either crash or SILENTLY CORRUPT another 
                          // data structure in your program.  

    printf("%d", *ptr);   //Print contents of same random memory address
                          // May or may not crash, depending on who owns this address

    return 0;             
}

Second Program with comments

#include <stdio.h>

int main(){
    int *ptr;              //Create pointer to random memory address

    int q = 50;            //Create local variable with contents int 50

    ptr = &q;              //Update address targeted by above created pointer to point
                           // to local variable your program properly created

    printf("%d", *ptr);    //Happily print the contents of said local variable (q)
    return 0;
}

The key is you cannot use a pointer until you know it is assigned to an address that you yourself have managed, either by pointing it at another variable you created or to the result of a malloc call.

Using it before is creating code that depends on uninitialized memory which will at best crash but at worst work sometimes, because the random memory address happens to be inside the memory space your program already owns. God help you if it overwrites a data structure you are using elsewhere in your program.

unique_ptr doesn't have the traditional copy constructor. Instead it has a "move constructor" that uses rvalue references:

unique_ptr::unique_ptr(unique_ptr && src);

An rvalue reference (the double ampersand) will only bind to an rvalue. That's why you get an error when you try to pass an lvalue unique_ptr to a function. On the other hand, a value that is returned from a function is treated as an rvalue, so the move constructor is called automatically.

By the way, this will work correctly:

bar(unique_ptr<int>(new int(44));

The temporary unique_ptr here is an rvalue.

But here's the rub, sometimes you can't or don't want to wait. For example I want to use the new support for RubyMotion which includes RubyMotion project structure support, setup of rake files, setup of configurations that are hooked to iOS Simulator etc.

RubyMine has all of these now, IDEA does not. So I would have to generate a RubyMotion project outside of IDEA, then setup an IDEA project and hook up to that source folder etc and God knows what else.

What JetBrains should do is have a licensing model that would allow me, with the purchase of IDEA to use any of other IDEs, as opposed to just relying on IDEAs plugins.

I would be willing to pay more for that i.e. say 50 bucks more for said flexibility.

The funny thing is, I was originally a RubyMine customer that upgraded to IDEA, because I did want that polyglot setup. Now I'm contemplating paying for the upgrade of RubyMine, just because I need to do RubyMotion now. Also there are other potential areas where this out of sync issue might bite me again . For example torque box workflow / deployment support.

JetBrains has good IDEs but I guess I'm a bit annoyed.

random_state number splits the test and training datasets with a random manner. In addition to what is explained here, it is important to remember that random_state value can have significant effect on the quality of your model (by quality I essentially mean accuracy to predict). For instance, If you take a certain dataset and train a regression model with it, without specifying the random_state value, there is the potential that everytime, you will get a different accuracy result for your trained model on the test data. So it is important to find the best random_state value to provide you with the most accurate model. And then, that number will be used to reproduce your model in another occasion such as another research experiment. To do so, it is possible to split and train the model in a for-loop by assigning random numbers to random_state parameter:

for j in range(1000):

            X_train, X_test, y_train, y_test = train_test_split(X, y , random_state =j,     test_size=0.35)
            lr = LarsCV().fit(X_train, y_train)

            tr_score.append(lr.score(X_train, y_train))
            ts_score.append(lr.score(X_test, y_test))

        J = ts_score.index(np.max(ts_score))

        X_train, X_test, y_train, y_test = train_test_split(X, y , random_state =J, test_size=0.35)
        M = LarsCV().fit(X_train, y_train)
        y_pred = M.predict(X_test)`

Here's the simplest solution (Jibwa made it seem complicated in another answer), without having to generate indices yourself - just using the ShuffleSplit object to generate 1 split.

import numpy as np 
from sklearn.model_selection import ShuffleSplit # or StratifiedShuffleSplit
sss = ShuffleSplit(n_splits=1, test_size=0.1)

data_size = 100
X = np.reshape(np.random.rand(data_size*2),(data_size,2))
y = np.random.randint(2, size=data_size)

sss.get_n_splits(X, y)
train_index, test_index = next(sss.split(X, y)) 

X_train, X_test = X[train_index], X[test_index] 
y_train, y_test = y[train_index], y[test_index]

I had same error and the mistake was that I had added list and dictionary into the same list (object) and when I used to iterate over the list of dictionaries and use to hit a list (type) object then I used to get this error.

Its was a code error and made sure that I only added dictionary objects to that list and list typed object into the list, this solved my issue as well.

In Addition to @Dev Blanked answer, if you want to use an existing bean that was created by Spring the code can be modified to:

@RunWith(MockitoJUnitRunner.class)
public class DemoTest {

    @Inject
    private ApplicationContext ctx;

    @Spy
    private SomeService service;

    @InjectMocks
    private Demo demo;

    @Before
    public void setUp(){
        service = ctx.getBean(SomeService.class);
    }

    /* ... */
}

This way you don't need to change your code (add another constructor) just to make the tests work.

This will get you to an answer for your simple case, but can you expand on how you'll know which columns will need to be compared (B and C in this case) and what the initial range (A1:D5 in this case) will be? Then I can try to provide a more complete answer.

Sub setCondFormat()
    Range("B3").Select
    With Range("B3:H63")
        .FormatConditions.Add Type:=xlExpression, Formula1:= _
          "=IF($D3="""",FALSE,IF($F3>=$E3,TRUE,FALSE))"
        With .FormatConditions(.FormatConditions.Count)
            .SetFirstPriority
            With .Interior
                .PatternColorIndex = xlAutomatic
                .Color = 5287936
                .TintAndShade = 0
            End With
        End With
    End With
End Sub

Note: this is tested in Excel 2010.

Edit: Updated code based on comments.

^{Assuming you actually mean timestamp because there is no datetime in Postgres}

Cast the timestamp column to a date, that will remove the time part:

select *
from the_table
where the_timestamp_column::date = date '2015-07-15';

This will return all rows from July, 15th.

Note that the above will not use an index on the_timestamp_column. If performance is critical, you need to either create an index on that expression or use a range condition:

select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
  and the_timestamp_column < timestamp '2015-07-16 00:00:00';

Java strings are interesting. It looks like the responses have covered some of the interesting points. Here are my two cents.

strings are immutable (you can never change them)

String x = "x";
x = "Y"; 

• The first line will create a variable x which will contain the string value "x". The JVM will look in its pool of string values and see if "x" exists, if it does, it will point the variable x to it, if it does not exist, it will create it and then do the assignment
• The second line will remove the reference to "x" and see if "Y" exists in the pool of string values. If it does exist, it will assign it, if it does not, it will create it first then assignment. As the string values are used or not, the memory space in the pool of string values will be reclaimed.

string comparisons are contingent on what you are comparing

String a1 = new String("A");

String a2 = new String("A");

• a1 does not equal a2
• a1 and a2 are object references
• When string is explicitly declared, new instances are created and their references will not be the same.

I think you're on the wrong path with trying to use the caseinsensitive class. Leave the strings alone. What you really care about is how you display or compare the values. Use another class to format the string or to make comparisons.

i.e.

TextUtility.compare(string 1, string 2) 
TextUtility.compareIgnoreCase(string 1, string 2)
TextUtility.camelHump(string 1)

Since you are making up the class, you can make the compares do what you want - compare the text values.

You may use DateInterval for this purpose;

$currentDate = new \DateTime(); //creates today timestamp
$currentDate->add(new \DateInterval('P5Y')); //this means 5 Years
and you can now format it;
$currentDate->format('Y-m-d');

Both means "every item in a set of two things". The two things being "left" and "right"

Try the code below and.....

1 - change the name of the MENU as in my sample the menuitem was called 'Form7ToolStripMenuItem_Click'

2 - make SURE to paste it into an MDIFORM and not just a basic FORM

Then let me know if the CHILD form still shows OUTSIDE the parent form

Private Sub Form7ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Form7ToolStripMenuItem.Click

    Dim NewForm As System.Windows.Forms.Form
    NewForm = New System.Windows.Forms.Form
    'USE THE NEXT LINE - to add an existing CUSTOM form you already have
    'NewForm = Form7                         
    NewForm.Width = 400
    NewForm.Height = 250
    NewForm.MdiParent = Me
    NewForm.Text = "CAPTION"
    NewForm.Show()
    DockChildForm(NewForm, "left")          'dock left
    'DockChildForm(NewForm, "right")         'dock right
    'DockChildForm(NewForm, "top")           'dock top
    'DockChildForm(NewForm, "bottom")        'doc bottom
    'DockChildForm(NewForm, "full")          'fill the client area (maximise the child INSIDE the parent)
    'DockChildForm(NewForm, "Anything-Else") 'center the form

End Sub

Private Sub DockChildForm(ByRef Form2Dock As Form, ByVal Position As String)

    Dim XYpoint As Point
    Select Case Position
        Case "left"
            Form2Dock.Dock = DockStyle.Left
        Case "top"
            Form2Dock.Dock = DockStyle.Top
        Case "right"
            Form2Dock.Dock = DockStyle.Right
        Case "bottom"
            Form2Dock.Dock = DockStyle.Bottom
        Case "full"
            Form2Dock.Dock = DockStyle.Fill
        Case Else
            XYpoint = New Point
            XYpoint.X = ((Me.ClientSize.Width - Form2Dock.Width) / 2)
            XYpoint.Y = ((Me.ClientSize.Height - Form2Dock.Height) / 2)
            Form2Dock.Location = XYpoint
    End Select
End Sub

While your solution should work, it can be difficult to read depending on the skill level of your fellow programmers. Additionally, it moves functionality away from the call site. Which can make maintenance a little more difficult.

I'm not sure if your goal is to get the keys into a vector or print them to cout so I'm doing both. You may try something like this:

std::map<int, int> m;
std::vector<int> key, value;
for(std::map<int,int>::iterator it = m.begin(); it != m.end(); ++it) {
  key.push_back(it->first);
  value.push_back(it->second);
  std::cout << "Key: " << it->first << std::endl();
  std::cout << "Value: " << it->second << std::endl();
}

Or even simpler, if you are using Boost:

map<int,int> m;
pair<int,int> me; // what a map<int, int> is made of
vector<int> v;
BOOST_FOREACH(me, m) {
  v.push_back(me.first);
  cout << me.first << "\n";
}

Personally, I like the BOOST_FOREACH version because there is less typing and it is very explicit about what it is doing.

I had trouble with VS 2017 finding my UnitTest as well. It wasn't the exact problem John was asking - but this was the first result in google that I came looking for so I wanted to share my issue.

I had a legacy solution coming back from VS2010 going over VS2013, VS2015. Now in VS2017 it seems namespaces for the [TestMethod] Attribute have changed.

Before it was using

Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0

I created a new Test.dll in the project and that one used by default

Microsoft.VisualStudio.TestPlatform.TestFramework, Version=14.0.0.0

So my solution was to create a new UnitTest project from within VS2017. Maybe changing assembly references for the old test project would have worked as well. With the new reference VS2017 did discover those unit tests.

Another option: Do not float your right column; just give it a left margin to move it beyond the float. You'll need a hack or two to fix IE6, but that's the basic idea.

Use jQuery $(document) function...

$(document).ready(function(){

var margin = {top: 20, right: 20, bottom: 30, left: 40},
    width = 960 - margin.left - margin.right,
    height = 500 - margin.top - margin.bottom;

var x0 = d3.scale.ordinal()
    .rangeRoundBands([0, width], .1);

var x1 = d3.scale.ordinal();

var y = d3.scale.linear()
    .range([height, 0]);

var color = d3.scale.ordinal()
    .range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);

var xAxis = d3.svg.axis()
    .scale(x0)
    .orient("bottom");

var yAxis = d3.svg.axis()
    .scale(y)
    .orient("left")
    .tickFormat(d3.format(".2s"));

//d3.select('#chart svg')
//d3.select("body").append("svg")


    //var svg = d3.select("#chart").append("svg:svg");

    var svg = d3.select("#BarChart").append("svg:svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
    .append("g")
    .attr("transform", "translate(" + margin.left + "," + margin.top + ")");

    var updateData = function(getData){

    d3.selectAll('svg > g > *').remove();

    d3.csv(getData, function(error, data) {
      if (error) throw error;

      var ageNames = d3.keys(data[0]).filter(function(key) { return key !== "State"; });

      data.forEach(function(d) {
        d.ages = ageNames.map(function(name) { return {name: name, value: +d[name]}; });
      });

      x0.domain(data.map(function(d) { return d.State; }));
      x1.domain(ageNames).rangeRoundBands([0, x0.rangeBand()]);
      y.domain([0, d3.max(data, function(d) { return d3.max(d.ages, function(d) { return d.value; }); })]);

      svg.append("g")
          .attr("class", "x axis")
          .attr("transform", "translate(0," + height + ")")
          .call(xAxis);

      svg.append("g")
          .attr("class", "y axis")
          .call(yAxis)
        .append("text")
          .attr("transform", "rotate(-90)")
          .attr("y", 6)
          .attr("dy", ".71em")
          .style("text-anchor", "end")
          .text("Population");

      var state = svg.selectAll(".state")
          .data(data)
        .enter().append("g")
          .attr("class", "state")
          .attr("transform", function(d) { return "translate(" + x0(d.State) + ",0)"; });

      state.selectAll("rect")
          .data(function(d) { return d.ages; })
        .enter().append("rect")
          .attr("width", x1.rangeBand())
          .attr("x", function(d) { return x1(d.name); })
          .attr("y", function(d) { return y(d.value); })
          .attr("height", function(d) { return height - y(d.value); })
          .style("fill", function(d) { return color(d.name); });

      var legend = svg.selectAll(".legend")
          .data(ageNames.slice().reverse())
        .enter().append("g")
          .attr("class", "legend")
          .attr("transform", function(d, i) { return "translate(0," + i * 20 + ")"; });

      legend.append("rect")
          .attr("x", width - 18)
          .attr("width", 18)
          .attr("height", 18)
          .style("fill", color);

      legend.append("text")
          .attr("x", width - 24)
          .attr("y", 9)
          .attr("dy", ".35em")
          .style("text-anchor", "end")
          .text(function(d) { return d; });

    });

}

updateData('data1.csv');

});

You don't need to do special things in the form. You just build the comment correctly in the show action:

class ArticlesController < ActionController::Base
  ....
  def show
    @article = Article.find(params[:id])
    @new_comment = @article.comments.build
  end
  ....
end

and then make a form for it in the article view:

<% form_for @new_comment do |f| %>
   <%= f.text_area :text %>
   <%= f.submit "Post Comment" %>
<% end %>

by default, this comment will go to the create action of CommentsController, which you will then probably want to put redirect :back into so you're routed back to the Article page.

Wireshark if you want to see everything going on in the network.

Fiddler if you want to just monitor HTTP/s traffic.

Live HTTP Headers if you're in Firefox and want a quick plugin just to see the headers.

Also FireBug can get you that information too and provides a nice interface when your working on a single page during development. I've used it to monitor AJAX transactions.

int arsize(int st1[]) {
    int i = 0;
    for (i; !(st1[i] & (1 << 30)); i++);
    return i;
}

This works for me :)

Same as best answer, just in case you need to print image as i did:

In case you want to print image:

function printElem(elem)
    {
        Popup(jQuery(elem).attr('src'));
    }

    function Popup(data) 
    {
        var mywindow = window.open('', 'my div', 'height=400,width=600');
        mywindow.document.write('<html><head><title>my div</title>');
        mywindow.document.write('</head><body >');
        mywindow.document.write('<img src="'+data+'" />');
        mywindow.document.write('</body></html>');

        mywindow.print();
        mywindow.close();

        return true;
    }

You have to submit data and reload page (server side render form with data), just reloading will not preserve data. It is just your browser might be caching form data on manual refresh (not same across browsers).

i was facing same issue in beautiful soup , I solved this issue by this command , your issue will also get rectified . You are unable to install requests in python 3.4 because your python libraries are not updated . use this command apt-get install python3-requests Just run it will ask you to add 222 MB space in your hard disk , just press Y and wait for completing process, after ending up whole process . check your problem will be resolved.

Here is a properly described article and also a sample with code. JS coordinates

As per requirement. below is code which is posted at last in that article. Need to call getOffset function and pass html element which returns its top and left values.

function getOffsetSum(elem) {
  var top=0, left=0
  while(elem) {
    top = top + parseInt(elem.offsetTop)
    left = left + parseInt(elem.offsetLeft)
    elem = elem.offsetParent        
  }

  return {top: top, left: left}
}


function getOffsetRect(elem) {
    var box = elem.getBoundingClientRect()

    var body = document.body
    var docElem = document.documentElement

    var scrollTop = window.pageYOffset || docElem.scrollTop || body.scrollTop
    var scrollLeft = window.pageXOffset || docElem.scrollLeft || body.scrollLeft

    var clientTop = docElem.clientTop || body.clientTop || 0
    var clientLeft = docElem.clientLeft || body.clientLeft || 0

    var top  = box.top +  scrollTop - clientTop
    var left = box.left + scrollLeft - clientLeft

    return { top: Math.round(top), left: Math.round(left) }
}


function getOffset(elem) {
    if (elem.getBoundingClientRect) {
        return getOffsetRect(elem)
    } else {
        return getOffsetSum(elem)
    }
}

In addition @Fredrik Mörk's great answer on strings, to add localization to a form do the following:

• Set the form's property "Localizable" to true
• Change the form's Language property to the language you want (from a nice drop-down with them all in)
• Translate the controls in that form and move them about if need be (squash those really long full French sentences in!)

Edit: This MSDN article on Localizing Windows Forms is not the original one I linked ... but might shed more light if needed. (the old one has been taken away)

You can just run an interactive shell container using that image and explore whatever content that image has.

For instance:

docker run -it image_name sh

Or following for images with an entrypoint

docker run -it --entrypoint sh image_name

Or, if you want to see how the image was build, meaning the steps in its Dockerfile, you can:

docker image history --no-trunc image_name > image_history

The steps will be logged into the image_history file.

Without giving the database name the table is can't be renamed in my case, I followed the below command to rename the table.

RENAME TABLE current_db.tbl_name TO current_db.tbl_name;

By using Chrome or Opera

without any plugins, without writing any single XPath syntax character

1. right click the required element, then "inspect"
2. right click on highlighted element tag, choose Copy ? Copy XPath.

;)

The below should work for you assuming Strings is the array that you are searching within:

Arrays.binarySearch(Strings,"mykeytosearch",mysearchComparator);

where mykeytosearch is the string that you want to test for existence within the array. mysearchComparator - is a comparator that would be used to compare strings.

Refer to Arrays.binarySearch for more information.

Similar problem for me. My class name was different to my file name. The connectionstring generated had the class name and not the file name in. Solution for me was just to rename my file to match the class name.

<description><![CDATA[first line<br/>second line<br/>]]></description>

SSIS is a no-brainer for doing stuff like this and is very straight forward (and this is just the kind of thing it is for).

1. Right-click the database in SQL Management Studio
2. Go to Tasks and then Export data, you'll then see an easy to use wizard.
3. Your database will be the source, you can enter your SQL query
4. Choose Excel as the target
5. Run it at end of wizard

If you wanted, you could save the SSIS package as well (there's an option at the end of the wizard) so that you can do it on a schedule or something (and even open and modify to add more functionality if needed).

In case where pwd can't be used (e.g. calling a scripts from a different location), use realpath (with or without dirname):

$(dirname $(realpath $PATH_TO_BE_RESOLVED))

Works both when calling through (multiple) symlink(s) or when directly calling the script - from any location.

Your -vm argument seems ok BUT it's position is wrong. According to this Eclipse Wiki entry :

The -vm option must occur before the -vmargs option, since everything after -vmargs is passed directly to the JVM.

So your -vm argument is not taken into account and it fails over to your default java installation, which is probably 1.6.0_65.

Using an absolute or relative string as the filename.

name_of_file = input("What is the name of the file: ")
completeName = '/home/user/Documents'+ name_of_file + ".txt"
file1 = open(completeName , "w")
toFile = input("Write what you want into the field")
file1.write(toFile)
file1.close()

In numpy, index and dimension numbering starts with 0. So axis 0 means the 1st dimension. Also in numpy a dimension can have length (size) 0. The simplest case is:

In [435]: x = np.zeros((0,), int)
In [436]: x
Out[436]: array([], dtype=int32)
In [437]: x[0]
...
IndexError: index 0 is out of bounds for axis 0 with size 0

I also get it if x = np.zeros((0,5), int), a 2d array with 0 rows, and 5 columns.

So someplace in your code you are creating an array with a size 0 first axis.

When asking about errors, it is expected that you tell us where the error occurs.

Also when debugging problems like this, the first thing you should do is print the shape (and maybe the dtype) of the suspected variables.

Applied to pandas

• The same error can occur for those using pandas, when sending a Series or DataFrame to a numpy.array, as with the following:
  • pandas.Series.values or pandas.Series.to_numpy() or pandas.Series.array
  • pandas.DataFrame.values or pandas.DataFrame.to_numpy()

Resolving the error:

1. Use a try-except block
2. Verify the size of the array is not 0
   • if x.size != 0:

If you want to add an interval before executing the cron the next time you can add a sleep

This is what I do when I need to add months or years and don't want to import more libraries. Just create a datetime.date() object, call add_month(date) to add a month and add_year(date) to add a year.

                return True
            else:
                return False

    if date.day > next_month_days:

Remove pathlib and reinstall it. Delete the pathlib in sitepackages folder and reinstall the pathlib package by using pip command:

pip install pathlib

The easiest way would be using Substring

string str = "AM0122200204";
string substr = str.Substring(str.Length - 3);

Using the overload with one int as I put would get the substring of a string, starting from the index int. In your case being str.Length - 3, since you want to get the last three chars.

SELECT SUM(IF(your_column=3,1,0)) FROM your_table WHERE your_where_contion='something';

e.g. for you query:-

SELECT SUM(IF(num=1,1,0)) FROM your_table_name;

One thing you can also do is Extend date object to return Weekday by:

Date.prototype.getWeekDay = function() {
    var weekday = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
    return weekday[this.getDay()];
}

so, you can only call date.getWeekDay();

This is a specific issue for Windows Vista, 7, 8 (and presumably newer).

User Account Control (UAC) is a feature in Windows that can help you stay in control of your computer by informing you when a program makes a change that requires administrator-level permission. UAC works by adjusting the permission level of your user account.

This is applied mostly to C:\Program Files. You may have noticed sometimes, that some applications can see files in C:\Program Files that does not exist there. You know why? Windows now tend to have "C:\Program Files" folder customized for every user. For example, old applications store config files (like .ini) in the same folder where the executable files are stored. In the good old days all users had the same configurations for such apps. In nowadays Windows stores configs in the special folder tied to the user account. Thus, now different users may have different configs while application still think that config files are in the same folder with the executables.

XAMPP does not like to have different config for different users. In fact it is not a config file for XAMPP, it is folders where you keep your projects and databases. The idea of XAMPP is to make projects same for all users. This is a source of a conflict with Windows.

All you need is to avoid installing XAMPP into C:\Program Files. Thus XAMPP will always use the original files for all users and there would be no confusion.

I recommend to install XAMPP into the special folder in root directory like in C:\XAMPP. But before you choose the folder you need to click on this warning message.

First you to add a class then remove id

<script type="text/javascript">
$(document).ready(function(){   
 $("#page_navigation1").addClass("page_navigation");        

 $("#add").click(function(){
        $(".page_navigation").attr("id","page_navigation1");
    });     
    $("#remove").click(function(){
        $(".page_navigation").removeAttr("id");
    });     
  });
</script>

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

The best (and only) method is to set correct HTTP headers, specifically these ones: "Expires", "Last-Modified", and "Cache-Control". How to do it depends on the server software you use.

In Improving performance… look for "Optimization on server side" for general considerations and relevant links and for "Client-side cache" for the Apache-specific advice.

If you are a fan of nginx (or nginx in plain English) like I am, you can easily configure it too:

location /images {
  ...
  expires 4h;
}

In the example above any file from /images/ will be cached on the client for 4 hours.

Now when you know right words to look for (HTTP headers "Expires", "Last-Modified", and "Cache-Control"), just peruse the documentation of the web server you use.

Starting from Postman 8 you need to visit here

There are two pair of modal events, one is "show" and "shown", the other is "hide" and "hidden". As you can see from the name, hide event fires when modal is about the be close, such as clicking on the cross on the top-right corner or close button or so on. While hidden is fired after the modal is actually close. You can test these events your self. For exampel:

$( '#modal' )
   .on('hide', function() {
       console.log('hide');
   })
   .on('hidden', function(){
       console.log('hidden');
   })
   .on('show', function() {
       console.log('show');
   })
   .on('shown', function(){
      console.log('shown' )
   });

And, as for your question, I think you should listen to the 'hide' event of your modal.

For my case gulp-ignore was perfect. As option you may pass a function there:

function condition(file) {
 // do whatever with file.path
 // return boolean true if needed to exclude file 
}

And the task would look like this:

var gulpIgnore = require('gulp-ignore');

gulp.task('task', function() {
  gulp.src('./**/*.js')
    .pipe(gulpIgnore.exclude(condition))
    .pipe(gulp.dest('./dist/'));
});

You can do as:

import pandas as pd
df = pd.read_csv('file_location\filename.txt', delimiter = "\t")

(like, df = pd.read_csv('F:\Desktop\ds\text.txt', delimiter = "\t")

use the below code please :

    Properties p = new Properties(); 
    StringBuffer path = new StringBuffer("com/al/common/email/templates/");
    path.append("foo.properties");
    InputStream fs = getClass().getClassLoader()
                                    .getResourceAsStream(path.toString());

if(fs == null){
System.err.println("Unable to load the properties file");
}
else{
try{
p.load(fs);
}
catch (IOException e) {
e.printStackTrace();
}
}

You guys should also make sure that when you override onLayout you HAVE to call super.onLayout with all of the properties, or the view will not be inflated!

Given that canvas is a canvas element,

const context = canvas.getContext('2d');

context.clearRect(0, 0, canvas.width, canvas.height);

I'm supposing you're using integer math for a reason. If so, you can get a result that's functionally nearly the same as POSITIVE_INFINITY by using the MAX_VALUE field of the Integer class:

Integer myInf = Integer.MAX_VALUE;

(And for NEGATIVE_INFINITY you could use MIN_VALUE.) There will of course be some functional differences, e.g., when comparing myInf to a value that happens to be MAX_VALUE: clearly this number isn't less than myInf. Also, as noted in the comments below, incrementing positive infinity will wrap you back around to negative numbers (and decrementing negative infinity will wrap you back to positive).

There's also a library that actually has fields POSITIVE_INFINITY and NEGATIVE_INFINITY, but they are really just new names for MAX_VALUE and MIN_VALUE.

I did a similar thing a few months ago, and it turned out this simple format was enough for Hudson to accept it as a test protocol:

<testsuite tests="3">
    <testcase classname="foo1" name="ASuccessfulTest"/>
    <testcase classname="foo2" name="AnotherSuccessfulTest"/>
    <testcase classname="foo3" name="AFailingTest">
        <failure type="NotEnoughFoo"> details about failure </failure>
    </testcase>
</testsuite>

This question has answers with more details: Spec. for JUnit XML Output

You can use the path module to join the path of the directory in which helper1.js lives to the relative path of foobar.json. This will give you the absolute path to foobar.json.

var fs = require('fs');
var path = require('path');

var jsonPath = path.join(__dirname, '..', 'config', 'dev', 'foobar.json');
var jsonString = fs.readFileSync(jsonPath, 'utf8');

This should work on Linux, OSX, and Windows assuming a UTF8 encoding.

If the problem is a serious-enough annoyance to you, you might consider virtualenv. It allows you to create an environment that encapsulates python libraries. You install packages there rather than in the global site-packages directory. Any scripts you run in that environment have access to those packages (and optionally, your global ones as well). I use this a lot when evaluating packages that I am not sure I want/need to install globally. If you decide you don't need the package, it's easy enough to just blow that virtual environment away. It's pretty easy to use. Make a new env:

$>virtualenv /path/to/your/new/ENV

virtual_envt installs setuptools for you in the new environment, so you can do:

$>ENV/bin/easy_install

You can even create your own boostrap scripts that setup your new environment. So, with one command, you can create a new virtual env with, say, python 2.6, psycopg2 and django installed by default (you can can install an env-specific version of python if you want).

The filter option filters only the first level subkey below ansible_facts

You can also pass arguments to getters by returning a function. This is particularly useful when you want to query an array in the store:

getters: {
  // ...
  getTodoById: (state) => (id) => {
    return state.todos.find(todo => todo.id === id)
  }
}
store.getters.getTodoById(2) // -> { id: 2, text: '...', done: false }

Note that getters accessed via methods will run each time you call them, and the result is not cached.

That is called Method-Style Access and it is documented on the Vue.js docs.

Sorry, don't have enough rep, or would have commented on CraigTP's answer.

I found the solution from the 1st link - C# Editable ListView, quite easy to use. The general idea is to:

• identify the SubItem that was selected and overlay a TextBox with the SubItem's text over the SubItem
• give this TextBox focus
• change SubItem's text to that of TextBox's when TextBox loses focus

What a workaround for a seemingly simple operation :-|

In my case, the error was just fatal: refusing to merge unrelated histories on every try, especially the first pull request after remotely adding a Git repository.

Using the --allow-unrelated-histories flag worked with a pull request in this way:

git pull origin branchname --allow-unrelated-histories

Parameters and Arguments

All the different terms that have to do with parameters and arguments can be confusing. However, if you keep a few simple points in mind, you will be able to easily handle these terms.

1. The formal parameters for a function are listed in the function declaration and are used in the body of the function definition. A formal parameter (of any sort) is a kind of blank or placeholder that is filled in with something when the function is called.
2. An argument is something that is used to fill in a formal parameter. When you write down a function call, the arguments are listed in parentheses after the function name. When the function call is executed, the arguments are plugged in for the formal parameters.
3. The terms call-by-value and call-by-reference refer to the mechanism that is used in the plugging-in process. In the call-by-value method only the value of the argument is used. In this call-by-value mechanism, the formal parameter is a local variable that is initialized to the value of the corresponding argument. In the call-by-reference mechanism the argument is a variable and the entire variable is used. In the call- by-reference mechanism the argument variable is substituted for the formal parameter so that any change that is made to the formal parameter is actually made to the argument variable.

That is,

If you want to know the number of physical cores (not virtual hyperthreaded cores), here is a platform independent solution:

psutil.cpu_count(logical=False)

https://github.com/giampaolo/psutil/blob/master/INSTALL.rst

Note that the default value for logical is True, so if you do want to include hyperthreaded cores you can use:

psutil.cpu_count()

This will give the same number as os.cpu_count() and multiprocessing.cpu_count(), neither of which have the logical keyword argument.

If you're looking for a int variable, one that increments as the code loops, you can use something like this:

@{
  int counter = 1;

  foreach (var item in Model.Stuff) {
    ... some code ...
    counter = counter + 1;
  }
} 

This is more or less a summary of three answers (by Sara Inés Calderón, klaxon and Gothburz), but as they all added something important, I consider it worth joining the solutions and adding some more explanation.

Considering your example, you can do calculations in your template using:

{{ 100 * (count/total) }}

However, this may result in a whole lot of decimal places, so using filters is a good way to go:

{{ 100 * (count/total) | number }}

By default, the number filter will leave up to three fractional digits, this is where the fractionSize argument comes in quite handy ({{ 100 * (count/total) | number:fractionSize }}), which in your case would be:

{{ 100 * (count/total) | number:0 }}

This will also round the result already:

angular.module('numberFilterExample', [])_x000D_
  .controller('ExampleController', ['$scope',_x000D_
    function($scope) {_x000D_
      $scope.val = 1234.56789;_x000D_
    }_x000D_
  ]);

        <td>No formatting:</td>_x000D_
        <td>_x000D_
          <span>{{ val }}</span>_x000D_
        </td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>3 Decimal places:</td>_x000D_
        <td>_x000D_
          <span>{{ val | number }}</span> (default)_x000D_
        </td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>2 Decimal places:</td>_x000D_
        <td><span>{{ val | number:2 }}</span></td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>No fractions: </td>_x000D_
        <td><span>{{ val | number:0 }}</span> (rounded)</td>_x000D_
      </tr>_x000D_
    </table>_x000D_
  </body>_x000D_
</html>

Last thing to mention, if you rely on an external data source, it probably is good practise to provide a proper fallback value (otherwise you may see NaN or nothing on your site):

{{ (100 * (count/total) | number:0) || 0 }}

Sidenote: Depending on your specifications, you may even be able to be more precise with your fallbacks/define fallbacks on lower levels already (e.g. {{(100 * (count || 10)/ (total || 100) | number:2)}}). Though, this may not not always make sense..

The notion of complex numbers was introduced in mathematics, from the need of calculating negative quadratic roots. Complex number concept was taken by a variety of engineering fields.

Today that complex numbers are widely used in advanced engineering domains such as physics, electronics, mechanics, astronomy, etc...

Real and imaginary part, of a negative square root example:

#include <stdio.h>   
#include <complex.h>

int main() 
{
    int negNum;

    printf("Calculate negative square roots:\n"
           "Enter negative number:");

    scanf("%d", &negNum);

    double complex negSqrt = csqrt(negNum);

    double pReal = creal(negSqrt);
    double pImag = cimag(negSqrt);

    printf("\nReal part %f, imaginary part %f"
           ", for negative square root.(%d)",
           pReal, pImag, negNum);

    return 0;
}

I think I've found it....from http://www-cs-students.stanford.edu/~blynn/gitmagic/ch02.html

Sometimes you just want to go back and forget about every change past a certain point because they're all wrong.

Start with:

$ git log

which shows you a list of recent commits, and their SHA1 hashes.

Next, type:

$ git reset --hard SHA1_HASH

to restore the state to a given commit and erase all newer commits from the record permanently.

This need is exactly why createInsecureRfcommSocketToServiceRecord() was added to BluetoothDevice starting in Android 2.3.3 (API Level 10) (SDK Docs)...before that there was no SDK support for this. It was designed to allow Android to connect to devices without user interfaces for entering a PIN code (like an embedded device), but it just as usable for setting up a connection between two devices without user PIN entry.

The corollary method listenUsingInsecureRfcommWithServiceRecord() in BluetoothAdapter is used to accept these types of connections. It's not a security breach because the methods must be used as a pair. You cannot use this to simply attempt to pair with any old Bluetooth device.

You can also do short range communications over NFC, but that hardware is less prominent on Android devices. Definitely pick one, and don't try to create a solution that uses both.

Hope that Helps!

P.S. There are also ways to do this on many devices prior to 2.3 using reflection, because the code did exist...but I wouldn't necessarily recommend this for mass-distributed production applications. See this StackOverflow.

For Intel graphics and AMD/ATI opensource graphics drivers

Find the "Device" section of /etc/X11/xorg.conf which contains one of the following directives:

• Driver "intel"
• Driver "radeon"
• Driver "fglrx"

And add the following line to that section:

Option     "SwapbuffersWait"       "false"

And run your application with vblank_mode environment variable set to 0:

$ vblank_mode=0 glxgears

For Nvidia graphics with the proprietary Nvidia driver

$ echo "0/SyncToVBlank=0" >> ~/.nvidia-settings-rc

The same change can be made in the nvidia-settings GUI by unchecking the option at X Screen 0 / OpenGL Settings / Sync to VBlank. Or, if you'd like to just test the setting without modifying your ~/.nvidia-settings-rc file you can do something like:

$ nvidia-settings --load-config-only --assign="SyncToVBlank=0"  # disable vertical sync
$ glxgears  # test it out
$ nvidia-settings --load-config-only  # restore your original vertical sync setting

the split() method takes a regular expression as an argument

The class which implements KeyListener interface becomes our custom key event listener. This listener can not directly listen the key events. It can only listen the key events through intermediate objects such as JFrame. So

1. Make one Key listener class as

   class MyListener implements KeyListener{
   
      // override all the methods of KeyListener interface.
   }
   

2. Now our class MyKeyListener is ready to listen the key events. But it can not directly do so.

3. Create any object like JFrame object through which MyListener can listen the key events. for that you need to add MyListener object to the JFrame object.

   JFrame f=new JFrame();
   f.addKeyListener(new MyKeyListener);
   

Try These steps if you have tried everything mentioned in above solutions:

1. Create File in android/app/src/main/assets
2. Run the following command :

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

3. Now run your command to build for e.g. react-native run-android

You can use:ls -lh, then you will get a list of file information

You could try this command, it should build and run the app (so .apk should be created) :

phonegap local run android

See: Multiple-line-syntax

It also support variables in multiline string, for example:

String name="zzg";
String lines = ""/**~!{
    SELECT * 
        FROM user
        WHERE name="$name"
}*/;
System.out.println(lines);

Output:

SELECT * 
    FROM user
    WHERE name="zzg"

You are close already. Just make sure to hide the checkbox and associate it with a label you style via input[checkbox] + label

You can view the filesystem of the container at

/var/lib/docker/devicemapper/mnt/$CONTAINER_ID/rootfs/

and you can just

tail -f mylogfile.log

Another alternative is to use a markdown editor like StackEdit. It converts html (or text) into markdown in a WYSIWYG editor. You can create indents, titles, lists in the editor, and it will show you the corresponding text in markdown format. You can then save, publish, share, or download the file. You can access it on their website - no downloads required!

Performance: No impact on performance as byte code is same. though it will lead to some compile overheads.

Compilation: on my personal machine, Compiling a blank class without importing anything takes 100 ms but same class when import java.* takes 170 ms.

How about this?

Date.prototype.withoutTime = function () {
    var d = new Date(this);
    d.setHours(0, 0, 0, 0);
    return d;
}

It allows you to compare the date part of the date like this without affecting the value of your variable:

var date1 = new Date(2014,1,1);
new Date().withoutTime() > date1.withoutTime(); // true

When you perform operations on Background thread and you want to update UI, you can not call or set anything from background thread. In case of WPF you need Dispatcher.BeginInvoke and in case of WinForms you need Invoke method.

WPF:

// assuming "this" is the window containing your progress bar..
// following code runs in background worker thread...
for(int i=0;i<count;i++)
{
    DoSomething();
    this.Dispatcher.BeginInvoke((Action)delegate(){
         this.progressBar.Value = (int)((100*i)/count);
    });
}

WinForms:

// assuming "this" is the window containing your progress bar..
// following code runs in background worker thread...
for(int i=0;i<count;i++)
{
    DoSomething();
    this.Invoke(delegate(){
         this.progressBar.Value = (int)((100*i)/count);
    });
}

for WinForms delegate may require some casting or you may need little help there, dont remember the exact syntax now.

'@icon sushi' is a portable utility that can create multiple icon ico file for free.

Drag & drop the different icon sizes, select them all and choose file -> create multiple icon.

You can download if from http://www.towofu.net/soft/e-aicon.php

from sysinternals.com with du.exe or du64.exe -l 1 . or 2 levels down: **du -l 2 c:**

Much shorter than Linux though ;)

I recommend doing it with webpack (assumes you're using webpack).

Defining constants is as simple as setting the webpack config file:

var webpack = require('webpack');
module.exports = {
    plugins: [
        new webpack.DefinePlugin({
            'APP_ENV': '"dev"',
            'process.env': {
                'NODE_ENV': '"development"'
            }
        })
    ],    
};

This way you define them outside your source, and they will be available in all your files.

This should work for you:

    $('.SeeMore2').click(function(){
        var $this = $(this);
        $this.toggleClass('SeeMore2');
        if($this.hasClass('SeeMore2')){
            $this.text('See More');         
        } else {
            $this.text('See Less');
        }
});

Your first problem is that you are passing -3 to the 2nd parameter of Columns.Add. It needs to be -2 for it to auto-size the column. Source: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columns.aspx (look at the comments on the code example at the bottom)

private void initListView()
{
    // Add columns
    lvRegAnimals.Columns.Add("Id", -2,HorizontalAlignment.Left);
    lvRegAnimals.Columns.Add("Name", -2, HorizontalAlignment.Left);
    lvRegAnimals.Columns.Add("Age", -2, HorizontalAlignment.Left);
}

You can also use the other overload, Add(string). E.g:

lvRegAnimals.Columns.Add("Id");
lvRegAnimals.Columns.Add("Name");
lvRegAnimals.Columns.Add("Age");

Reference for more overloads: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columnheadercollection.aspx

Second, to add items to the ListView, you need to create instances of ListViewItem and add them to the listView's Items collection. You will need to use the string[] constructor.

var item1 = new ListViewItem(new[] {"id123", "Tom", "24"});
var item2 = new ListViewItem(new[] {person.Id, person.Name, person.Age});
lvRegAnimals.Items.Add(item1);
lvRegAnimals.Items.Add(item2);

You can also store objects in the item's Tag property.

item2.Tag = person;

And then you can extract it

var person = item2.Tag as Person;

Let me know if you have any questions and I hope this helps!

I found that if you add the command to unload, he keeps down the page, ie the page that move! Hope it works with you too!

window.addEventListener("load", function() { window.scrollTo(0, 1); });
window.addEventListener("unload", function() { window.scrollTo(0, 1); });

Using a 7-inch tablet with android, www.kupsoft.com visit my website and check how it behaves page, I use this command in my portal.

You can use the root.configure(background='your colour') example:- import tkinter root=tkiner.Tk() root.configure(background='pink')

A database is the main container, it contains the data and log files, and all the schemas within it. You always back up a database, it is a discrete unit on its own.

Schemas are like folders within a database, and are mainly used to group logical objects together, which leads to ease of setting permissions by schema.

EDIT for additional question

drop schema test1

Msg 3729, Level 16, State 1, Line 1
Cannot drop schema 'test1' because it is being referenced by object 'copyme'.

You cannot drop a schema when it is in use. You have to first remove all objects from the schema.

In Firefox and Chrome (and possibly more) we can insert the string ‘( .... )’ into the alt text of an image that hasn’t loaded.

img {_x000D_
  font-style: italic;_x000D_
  color: #c00;_x000D_
}_x000D_
_x000D_
img:after {_x000D_
  content: " (Image - Right click to reload if not loaded)";_x000D_
}_x000D_
_x000D_
img::after {_x000D_
  content: " (Image - Right click to reload if not loaded)";_x000D_
}

<img alt="Alt text - " />

You could try this:

git reset --hard HEAD
git pull

(from How do I force "git pull" to overwrite local files?)

Another idea would be to delete the entire git and make a new clone.

DateTime dt = this.dateTimePicker1.Value.Date;

Quick-to-write alterantive

Even though is not the fastest choice, if performance is not an issue you can use:

sum(~np.isnan(data)).

Performance:

In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop

In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop

In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop

Here is two examples, one print the logs (stdout) the other write the logs to a file:

import logging
import sys

logger = logging.getLogger()
logger.setLevel(logging.INFO)
formatter = logging.Formatter('%(asctime)s | %(levelname)s | %(message)s')

stdout_handler = logging.StreamHandler(sys.stdout)
stdout_handler.setLevel(logging.DEBUG)
stdout_handler.setFormatter(formatter)

file_handler = logging.FileHandler('logs.log')
file_handler.setLevel(logging.DEBUG)
file_handler.setFormatter(formatter)


logger.addHandler(file_handler)
logger.addHandler(stdout_handler)

With this example, all logs will be printed and also be written to a file named logs.log

Use example:

logger.info('This is a log message!')
logger.error('This is an error message.')

I've had issues using AddDays(-1).

My solution is TimeSpan.

What bout this query (based on the description from manual)?

SELECT table_name
  FROM information_schema.tables
 WHERE table_schema='public'
   AND table_type='BASE TABLE';

Try to use this command :

date | cut -d " " -f2-4 | tr " " "-" 

The output would be like: 21-Feb-2021

If you're more comfortable working inside Excel/VBA, use the open event and test the environment: either have a signal file, a registry entry or an environment variable that controls what the open event does.

You can create the file/setting outside and test inside (use GetEnviromentVariable for env-vars) and test easily. I've written VBScript but the similarities to VBA cause me more angst than ease..

As I understand the problem, you want to use a spreadsheet normally most/some of the time yet have it run in batch and do something extra/different. You can open the sheet from the excel.exe command line but you can't control what it does unless it knows where it is. Using an environment variable is relatively simple and makes testing the spreadsheet easy.

To clarify, use the function below to examine the environment. In a module declare:

Private Declare Function GetEnvVar Lib "kernel32" Alias "GetEnvironmentVariableA" _
    (ByVal lpName As String, ByVal lpBuffer As String, ByVal nSize As Long) As Long

Function GetEnvironmentVariable(var As String) As String
Dim numChars As Long

    GetEnvironmentVariable = String(255, " ")

    numChars = GetEnvVar(var, GetEnvironmentVariable, 255)

End Function

In the Workbook open event (as others):

Private Sub Workbook_Open()
    If GetEnvironmentVariable("InBatch") = "TRUE" Then
        Debug.Print "Batch"
    Else
        Debug.Print "Normal"
    End If
End Sub

Add in active code as applicable. In the batch file, use

set InBatch=TRUE

Quick review,

• DB - Define Byte. 8 bits
• DW - Define Word. Generally 2 bytes on a typical x86 32-bit system
• DD - Define double word. Generally 4 bytes on a typical x86 32-bit system

From x86 assembly tutorial,

The pop instruction removes the 4-byte data element from the top of the hardware-supported stack into the specified operand (i.e. register or memory location). It first moves the 4 bytes located at memory location [SP] into the specified register or memory location, and then increments SP by 4.

Your num is 1 byte. Try declaring it with DD so that it becomes 4 bytes and matches with pop semantics.
