static variable

• It is a variable which belongs to the class and not to object(instance)
• Static variables are initialized only once , at the start of the execution(when the Classloader load the class for the first time) .
• These variables will be initialized first, before the initialization of any instance variables
• A single copy to be shared by all instances of the class
• A static variable can be accessed directly by the class name and doesn’t need any object

According to RFC 4329 the correct MIME type for JavaScript should be application/javascript. Howerver, older IE versions choke on this since they expect text/javascript.

You can also use Sugar.

Date.create().reset().set({seconds: 180}).format('{mm}:{ss}');

This example returns '03:00'.

I will make it simple,

• Import and Export are ES6 features(Next gen JS).
• Require is old school method of importing code from other files

Major difference is in require, entire JS file is called or imported. Even if you don't need some part of it.

var myObject = require('./otherFile.js'); //This JS file will be imported fully.

Whereas in import you can extract only objects/functions/variables which are required.

import { getDate }from './utils.js'; 
//Here I am only pulling getDate method from the file instead of importing full file

Another major difference is you can use require anywhere in the program where as import should always be at the top of file

If the data comes from an external library you might need to run the data upate statement within zone.run(...). Inject zone: NgZone for this. If you can run the instantiation of the external library within zone.run() already, then you might not need zone.run() later.

Improving the @Derek Springer post with fill length function:

public static String getFileWithDate(String fileName, String fileSaperator, String dateFormat) {
    String FileNamePrefix = fileName.substring(0, fileName.lastIndexOf(fileSaperator));
    String FileNameSuffix = fileName.substring(fileName.lastIndexOf(fileSaperator)+1, fileName.length());
    //System.out.println("File= Prefix~Suffix:"+FileNamePrefix +"~"+FileNameSuffix);
    
    String newFileName = new SimpleDateFormat("'"+FileNamePrefix+"_'"+dateFormat+"'"+fileSaperator+FileNameSuffix+"'").format(new Date());
    System.out.println("New File:"+newFileName);
    return newFileName;
}

Using the funciton and its Output:

String fileSaperator = ".", format = "yyyyMMMdd_HHmm";
getFileWithDate("Text1.txt", fileSaperator, format);
getFileWithDate("Text1.doc", fileSaperator, format);
getFileWithDate("Text1.txt.json", fileSaperator, format);

Output:

Old File:Text1.txt   New File:Text1_2020Nov11_1807.txt
Old File:Text1.doc   New File:Text1_2020Nov11_1807.doc
Old File:Text1.txt.json  New File:Text1.txt_2020Nov11_1807.json

In case someone is looking for list of files changed including staged files

git diff HEAD --name-only --relative --diff-filter=AMCR

git diff HEAD --name-only --relative --diff-filter=AMCR sha-1 sha-2

Remove --relative if you want absolute paths.

Visual Studio's search in folders is by far the fastest I've found.

I believe it intelligently searches only text (non-binary) files, and subsequent searches in the same folder are extremely fast, unlike with the other tools (likely the text files fit in the windows disk cache).

VS2010 on a regular hard drive, no SSD, takes 1 minute to search a 20GB folder with 26k files, source code and binaries mixed up. 15k files are searched - the rest are likely skipped due to being binary files. Subsequent searches in the same folder are on the order of seconds (until stuff gets evicted form the cache).

The next closest I've found for the same folder was grepWin. Around 3 minutes. I excluded files larger than 2000KB (default). The "Include binary files" setting seems to do nothing in terms of speeding up the search, it looks like binary files are still touched (bug?), but they don't show up in the search results. Subsequent searches all take the same 3 minutes - can't take advantage of hard drive cache. If I restrict to files smaller than 200k, the initial search is 2.5min and subsequent searches are on the order of seconds, about as fast as VS - in the cache.

Agent Ransack and FileSeek are both very slow on that folder, around 20min, due to searching through everything, including giant multi-gigabyte binary files. They search at about 10-20MB per second according to Resource Monitor.

UPDATE: Agent Ransack can be set to search files of certain sizes, and using the <200KB cutoff it's 1:15min for a fresh search and 5s for subsequent searches. Faster than grepWin and as fast as VS overall. It's actually pretty nice if you want to keep several searches in tabs and you don't want to pollute the VS recently searched folders list, and you want to keep the ability to search binaries, which VS doesn't seem to wanna do. Agent Ransack also creates an explorer context menu entry, so it's easy to launch from a folder. Same as grepWin but nicer UI and faster.

My new search setup is Agent Ransack for contents and Everything for file names (awesome tool, instant results!).

If you are in a submodule, don't forget to declare the module in main app. ie :

<scrip>
angular.module('mainApp', ['subModule1', 'subModule2']);

angular.module('subModule1')
   .controller('MyController', ['$scope', function($scope) {
      $scope.moduleName = 'subModule1';
   }]);
</script>
...
<div ng-app="mainApp">
   <div ng-controller="MyController">
   <span ng-bind="moduleName"></span>
</div>

If you don't declare subModule1 in mainApp, you will got a "[ng:areq] Argument "MyController" is not a function, got undefined.

Try:

$id =101;
$comments = EmailArchive::model()->findAll(
array("condition"=>"email_id =  $id","order"=>"id"));

OR

$id =101;
$criteria = new CDbCriteria();
$criteria->addCondition("email_id=:email_id");
$criteria->params = array(':email_id' => $id);
$comments = EmailArchive::model()->findAll($criteria);

OR

$Criteria = new CDbCriteria();
$Criteria->condition = "email_id = $id";
$Products = Product::model()->findAll($Criteria);

All those answer are good, but it somehow confuses newbie like me as it does not clarify compile check and runtime check. Preprocessor are before compile time, but we should make it clearer

This blog article shows How to detect the iPhone simulator? clearly

Runtime

First of all, let’s shortly discuss. UIDevice provides you already information about the device

[[UIDevice currentDevice] model]

will return you “iPhone Simulator” or “iPhone” according to where the app is running.

Compile time

However what you want is to use compile time defines. Why? Because you compile your app strictly to be run either inside the Simulator or on the device. Apple makes a define called TARGET_IPHONE_SIMULATOR. So let’s look at the code :

#if TARGET_IPHONE_SIMULATOR

NSLog(@"Running in Simulator - no app store or giro");

#endif

You are correct in guessing that the aim of using string builder is not achieved, at least not to its full extent.

However, when the compiler sees the expression "select id1, " + " id2 " + " from " + " table" it emits code which actually creates a StringBuilder behind the scenes and appends to it, so the end result is not that bad afterall.

But of course anyone looking at that code is bound to think that it is kind of retarded.

Probably you can implement generic static lookup method.

Like so

public class LookupUtil {
   public static <E extends Enum<E>> E lookup(Class<E> e, String id) {   
      try {          
         E result = Enum.valueOf(e, id);
      } catch (IllegalArgumentException e) {
         // log error or something here

         throw new RuntimeException(
           "Invalid value for enum " + e.getSimpleName() + ": " + id);
      }

      return result;
   }
}

Then you can

public enum MyEnum {
   static public MyEnum lookup(String id) {
       return LookupUtil.lookup(MyEnum.class, id);
   }
}

or call explicitly utility class lookup method.

Please check this: https://jsfiddle.net/wazb1jks/3/

navigator.getUserMedia(mediaConstraints, function(stream) {_x000D_
    window.streamReference = stream;_x000D_
}, onMediaError);

Stop Recording

function stopStream() {_x000D_
    if (!window.streamReference) return;_x000D_
_x000D_
    window.streamReference.getAudioTracks().forEach(function(track) {_x000D_
        track.stop();_x000D_
    });_x000D_
_x000D_
    window.streamReference.getVideoTracks().forEach(function(track) {_x000D_
        track.stop();_x000D_
    });_x000D_
_x000D_
    window.streamReference = null;_x000D_
}

Even when the question is regarding Java 7, I think it adds value to know that from Java 11 onward, there is a static method in Path class that allows to do this straight away:

With all the path in one String:

Path.of("/tmp/foo");

With the path broken down in several Strings:

Path.of("/tmp","foo");

As mentioned by Seeker, the problem could have been that you setup the click() function too soon. From your code snippet, we cannot know where you placed the script and whether it gets run at the right time.

An important point is to run such scripts after the document is ready. This is done by placing the click() initialization within that other function as in:

jQuery(document).ready(function()
  {
    jQuery("body").click(function()
      {
        // ... your click code here ...
      });
  });

This is usually the best method, especially if you include your JavaScript code in your <head> tag. If you include it at the very bottom of the page, then the ready() function is less important, but it may still be useful.

It's extremely unlikely that an if/else or a switch is going to be the source of your performance woes. If you're having performance problems, you should do a performance profiling analysis first to determine where the slow spots are. Premature optimization is the root of all evil!

Nevertheless, it's possible to talk about the relative performance of switch vs. if/else with the Java compiler optimizations. First note that in Java, switch statements operate on a very limited domain -- integers. In general, you can view a switch statement as follows:

switch (<condition>) {
   case c_0: ...
   case c_1: ...
   ...
   case c_n: ...
   default: ...
}

where c_0, c_1, ..., and c_N are integral numbers that are targets of the switch statement, and <condition> must resolve to an integer expression.

• If this set is "dense" -- that is, (max(c_i) + 1 - min(c_i)) / n > α, where 0 < k < α < 1, where k is larger than some empirical value, a jump table can be generated, which is highly efficient.

• If this set is not very dense, but n >= β, a binary search tree can find the target in O(2 * log(n)) which is still efficient too.

For all other cases, a switch statement is exactly as efficient as the equivalent series of if/else statements. The precise values of α and β depend on a number of factors and are determined by the compiler's code-optimization module.

Finally, of course, if the domain of <condition> is not the integers, a switch statement is completely useless.

If you want to format the JSON and also do some syntax highlighting, you can use the ng-prettyjson directive. See the npm package.

Here is how to use it: <pre pretty-json="jsonObject"></pre>

This can work as well.

if (tabControl.SelectedTab.Text == "tabText" )
{
    .. do stuff
}

If your deployment descriptor tab is disabled, then click on update libraries it will also do your work. It will create. Xml file in Web content

You can directly run the second query if you know the owner name.

--First you can select what all OWNERS there exist:

SELECT DISTINCT(owner) from SYS.ALL_TABLES;

--Then you can see the tables under by that owner:

SELECT table_name, owner from all_tables where owner like ('%XYZ%');

The difference is the implicit conversion when using AddWithValue. If you know that your executing SQL query (stored procedure) is accepting a value of type int, nvarchar, etc, there's no reason in re-declaring it in your code.

For complex type scenarios (example would be DateTime, float), I'll probably use Add since it's more explicit but AddWithValue for more straight-forward type scenarios (Int to Int).

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

There are two strategies:

1. Use Database-generated ID (int or GUID)

   Cons:

   You should perform SaveChanges() to get the ID for just saved entities.

   Pros:

   Can use int identity.

2. Use client generated ID - GUID only.

   Pros: Minification of SaveChanges operations. Able to insert a big graph of new objects per one operation.

   Cons:

   Allowed only for GUID

You can use:

You should chain your Lambda functions via SNS. This approach provides good performance, latency and scalability for minimal effort.

Your first Lambda publishes messages to your SNS Topic and the second Lambda is subscribed to this topic. As soon as messages arrive in the topic, second Lambda gets executed with the message as it's input parameter.

See Invoking Lambda functions using Amazon SNS notifications.

You can also use this approach to Invoke cross-account Lambda functions via SNS.

I stumbled here via Google and got my answer that Java is big endian.

Reading through the responses I'd like to point out that bytes do indeed have an endian order, although mercifully, if you've only dealt with “mainstream” microprocessors you are unlikely to have ever encountered it as Intel, Motorola, and Zilog all agreed on the shift direction of their UART chips and that MSB of a byte would be 2**7 and LSB would be 2**0 in their CPUs (I used the FORTRAN power notation to emphasize how old this stuff is :) ).

I ran into this issue with some Space Shuttle bit serial downlink data 20+ years ago when we replaced a $10K interface hardware with a Mac computer. There is a NASA Tech brief published about it long ago. I simply used a 256 element look up table with the bits reversed (table[0x01]=0x80 etc.) after each byte was shifted in from the bit stream.

It might be that the package "Combinations" is not updated anymore and does not work with a recent version of R (I was also unable to install it on R 2.13.1 on windows). The package "combinat" installs without problem for me and might be a solution for you depending on what exactly you're trying to do.

Difference between install, update and require

Assume the following scenario:

composer.json

"parsecsv/php-parsecsv": "0.*"

composer.lock file

  "name": "parsecsv/php-parsecsv",
            "version": "0.1.4",

Latest release is 1.1.0. The latest 0.* release is 0.3.2

install: composer install parsecsv/php-parsecsv

This will install version 0.1.4 as specified in the lock file

update: composer update parsecsv/php-parsecsv

This will update the package to 0.3.2. The highest version with respect to your composer.json. The entry in composer.lock will be updated.

require: composer require parsecsv/php-parsecsv

This will update or install the newest version 1.1.0. Your composer.lock file and composer.json file will be updated as well.

Create the classLoader instance of the class you need, then you can access the files or resources easily. now you access path using getPath() method of that class.

 ClassLoader classLoader = getClass().getClassLoader();
 String path  = classLoader.getResource("chromedriver.exe").getPath();
 System.out.println(path);

In a couple of lines, Cygwin and PowerShell are different tools however if you have Cygwin installed you can run the Cygwin executables within a PowerShell session. I've gotten so used to PowerShell that now I no longer use grep, sort, awk, etc. There are pretty much built-in alternatives in PowerShell, and if not you can find a cmdlet out there.

The main tool I find myself using is ssh.exe, but within a PowerShell session.

It works great.

:hover is a selector, and not a style. What you're doing in your example is adding inline styles to an element, and a selector equivalent for that obviously doesn't make much sense.

You can add a class to your link: hlRow.CssClass = 'abc'; And define your class as such:

a.abc:hover {
    ...
}

Append a semicolon to the following line to fix the issue.

   }
})

I hope this help.

I got the same message ("repository element was not specified in the POM inside distributionManagement element"). I checked /target/checkout/pom.xml and as per another answer and it really lacked <distributionManagement>.

It turned out that the problem was that <distributionManagement> was missing in pom.xml in my master branch (using git).

After cleaning up (mvn release:rollback, mvn clean, mvn release:clean, git tag -d v1.0.0) I run mvn release again and it worked.

As paxdiablo said make -f pax.mk would execute the pax.mk makefile, if you directly execute it by typing ./pax.mk, then you would get syntax error.

Also you can just type make if your file name is makefile/Makefile.

Suppose you have two files named makefile and Makefile in the same directory then makefile is executed if make alone is given. You can even pass arguments to makefile.

Check out more about makefile at this Tutorial : Basic understanding of Makefile

You can do this:

To show the dots instead of the password set the PasswordTransformationMethod:

yourEditText.setTransformationMethod(new PasswordTransformationMethod());

of course you can set this by default in your edittext element in the xml layout with

android:password

To re-show the readable password, just pass null as transformation method:

yourEditText.setTransformationMethod(null);

A key is just a normal index. A way over simplification is to think of it like a card catalog at a library. It points MySQL in the right direction.

A unique key is also used for improved searching speed, but it has the constraint that there can be no duplicated items (there are no two x and y where x is not y and x == y).

The manual explains it as follows:

A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. This constraint does not apply to NULL values except for the BDB storage engine. For other engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL. If you specify a prefix value for a column in a UNIQUE index, the column values must be unique within the prefix.

A primary key is a 'special' unique key. It basically is a unique key, except that it's used to identify something.

The manual explains how indexes are used in general: here.

In MSSQL, the concepts are similar. There are indexes, unique constraints and primary keys.

Untested, but I believe the MSSQL equivalent is:

CREATE TABLE tmp (
  id int NOT NULL PRIMARY KEY IDENTITY,
  uid varchar(255) NOT NULL CONSTRAINT uid_unique UNIQUE,
  name varchar(255) NOT NULL,
  tag int NOT NULL DEFAULT 0,
  description varchar(255),
);

CREATE INDEX idx_name ON tmp (name);
CREATE INDEX idx_tag ON tmp (tag);

Edit: the code above is tested to be correct; however, I suspect that there's a much better syntax for doing it. Been a while since I've used SQL server, and apparently I've forgotten quite a bit :).

This solution will do the trick in Chrome and Opera by setting margin to 0 in a css @page directive. It will not (currently) work for other browsers though...

In some cases, I could prevent Eclipse from crashing during startup by deleting a .snap file in your workspace meta-data (.metadata/.plugins/org.eclipse.core.resources/.snap).

Django 1.10 no longer allows you to specify views as a string (e.g. 'myapp.views.home') in your URL patterns.

The solution is to update your urls.py to include the view callable. This means that you have to import the view in your urls.py. If your URL patterns don't have names, then now is a good time to add one, because reversing with the dotted python path no longer works.

from django.conf.urls import include, url

from django.contrib.auth.views import login
from myapp.views import home, contact

urlpatterns = [
    url(r'^$', home, name='home'),
    url(r'^contact/$', contact, name='contact'),
    url(r'^login/$', login, name='login'),
]

If there are many views, then importing them individually can be inconvenient. An alternative is to import the views module from your app.

from django.conf.urls import include, url

from django.contrib.auth import views as auth_views
from myapp import views as myapp_views

urlpatterns = [
    url(r'^$', myapp_views.home, name='home'),
    url(r'^contact/$', myapp_views.contact, name='contact'),
    url(r'^login/$', auth_views.login, name='login'),
]

Note that we have used as myapp_views and as auth_views, which allows us to import the views.py from multiple apps without them clashing.

See the Django URL dispatcher docs for more information about urlpatterns.

None of these methods worked for me in .NET Core 2.2 but I was able to adapt some code I had for defining a different primary key to work for this purpose.

In the instance below I want to ensure the OutletRef field is unique:

public class ApplicationDbContext : IdentityDbContext
    {
        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<Outlet>()
                .HasIndex(o => new { o.OutletRef });
        }
    }

This adds the required unique index in the database. What it doesn't do though is provide the ability to specify a custom error message.

Also make sure your code doesn't have true for setBlockNetworkLoads

webView.getSettings().setBlockNetworkLoads (false);

The MDN documentation shows how the getItem method is implementated:

Object.defineProperty(oStorage, "getItem", {
      value: function (sKey) { return sKey ? this[sKey] : null; },
      writable: false,
      configurable: false,
      enumerable: false
    });

If the value isn't set, it returns null. You are testing to see if it is undefined. Check to see if it is null instead.

if(localStorage.getItem("username") === null){

Thanks for all the helpful suggestions. I finally made sure that there are no warnings in my code, but again was getting this warning from sqlite3:

Assuming signed overflow does not occur when assuming that (X - c) <= X is always true

which I fixed by adding the following CFLAG:

-fno-strict-overflow

Assuming you are using Python 3.x:

print(*myList, sep='\n')

You can get the same behavior on Python 2.x using from __future__ import print_function, as noted by mgilson in comments.

With the print statement on Python 2.x you will need iteration of some kind, regarding your question about print(p) for p in myList not working, you can just use the following which does the same thing and is still one line:

for p in myList: print p

For a solution that uses '\n'.join(), I prefer list comprehensions and generators over map() so I would probably use the following:

print '\n'.join(str(p) for p in myList) 

OS independent algorithm "Creating GUI applications in C++ in three steps":

1. Install Qt Creator

   

2. Create new project (Qt Widgets Application)

   

3. Build it.

Congratulations, you've got your first GUI in C++.

Now you're ready to read a lot of documentation to create something more complicate than "Hello world" GUI application.

adjustcolor("blanchedalmond",alpha.f = 0.3)

The above function provides a color code which corresponds to a transparent version of the input color (In this case the input color is "blanchedalmond.").

Input alpha values range on a scale of 0 to 1, 0 being completely transparent and 1 being completely opaque. (In this case, the code for the translucent shad of "blanchedalmond" given an alpha of .3 is "#FFEBCD4D." Be sure to include the hashtag symbol). You can make the new translucent color into the background color by using this function provided by joran earlier in this thread:

rect(par("usr")[1],par("usr")[3],par("usr")[2],par("usr")[4],col = "blanchedalmond")

By using a translucent color, you can be sure that the graph's data can still be seen underneath after the background color is applied. Hope this helps!

You can also use unlist(), which is often useful for handling lists:

> mylist <- list(A = c(1:3), B = c(4:6), C = c(7:9))

> mylist
$A
[1] 1 2 3

$B
[1] 4 5 6

$C
[1] 7 8 9

> unlist(mylist)
A1 A2 A3 B1 B2 B3 C1 C2 C3 
 1  2  3  4  5  6  7  8  9 

> length(unlist(mylist))
[1] 9

unlist() is a simple way of executing other functions on lists as well, such as:

> sum(mylist)
Error in sum(mylist) : invalid 'type' (list) of argument

> sum(unlist(mylist))
[1] 45

An Int (or TinyInt) aligned to an Enum field would be my methodology.

First, if you have a single bit field in a database, the row will still use a full byte, so as far as space savings, it only pays off if you have multiple bit fields.

Second, strings/chars have a "magic value" feel to them, regardless of how obvious they may seem at design time. Not to mention, it lets people store just about any value they would not necessarily map to anything obvious.

Third, a numeric value is much easier (and better practice) to create a lookup table for, in order to enforce referential integrity, and can correlate 1-to-1 with an enum, so there is parity in storing the value in memory within the application or in the database.

Try using the Worksheet.Protect method, like so:

Sub ProtectActiveSheet()
    Dim ws As Worksheet
    Set ws = ActiveSheet
    ws.Protect DrawingObjects:=True, Contents:=True, _
        Scenarios:=True, Password="SamplePassword"
End Sub

You should, however, be concerned about including the password in your VBA code. You don't necessarily need a password if you're only trying to put up a simple barrier that keeps a user from making small mistakes like deleting formulas, etc.

Also, if you want to see how to do certain things in VBA in Excel, try recording a Macro and looking at the code it generates. That's a good way to get started in VBA.

In Insert mode 
<C-A>   - Increments the number under cursor 
<C-X>   - Decrements the number under cursor

It will be very useful if we want to generate sequential numbers in vim
Lets say if we want to insert lines 1-10 with numbers from 1 to 10 [like "1" on 1st line,"2" on 2nd line..]
insert "0" on the first line and copy the line and past 9 times So that all lines will show "0".

Run the following Ex command

:g/^/exe "norm " . line(".") . "\<C-A>"

The Print statement in TSQL is a misunderstood creature, probably because of its name. It actually sends a message to the error/message-handling mechanism that then transfers it to the calling application. PRINT is pretty dumb. You can only send 8000 characters (4000 unicode chars). You can send a literal string, a string variable (varchar or char) or a string expression. If you use RAISERROR, then you are limited to a string of just 2,044 characters. However, it is much easier to use it to send information to the calling application since it calls a formatting function similar to the old printf in the standard C library. RAISERROR can also specify an error number, a severity, and a state code in addition to the text message, and it can also be used to return user-defined messages created using the sp_addmessage system stored procedure. You can also force the messages to be logged.

Your error-handling routines won’t be any good for receiving messages, despite messages and errors being so similar. The technique varies, of course, according to the actual way you connect to the database (OLBC, OLEDB etc). In order to receive and deal with messages from the SQL Server Database Engine, when you’re using System.Data.SQLClient, you’ll need to create a SqlInfoMessageEventHandler delegate, identifying the method that handles the event, to listen for the InfoMessage event on the SqlConnection class. You’ll find that message-context information such as severity and state are passed as arguments to the callback, because from the system perspective, these messages are just like errors.

It is always a good idea to have a way of getting these messages in your application, even if you are just spooling to a file, because there is always going to be a use for them when you are trying to chase a really obscure problem. However, I can’t think I’d want the end users to ever see them unless you can reserve an informational level that displays stuff in the application.

I had the same error. The cause was that I had created a table with wrong schema(it ought to be [dbo]). I did the following steps:

1. I dropped all tables which does not have a prefix "dbo."

2. I created and run this query:

CREATE TABLE dbo.Cars(IDCar int PRIMARY KEY NOT NULL,Name varchar(25) NOT NULL,    
CarDescription text NULL)
GO

finish() method is used to finish the activity and remove it from back stack. You can call it in any method in activity. But make sure you close all the Database connections, all reference variables null to prevent any memory leaks.

In MAC OS Catalina, this are the steps that worked for me, all the above solutions did help but didn't solve my problem.

1. check node --version, still the old one in use.
2. cd ~/
3. atom .bash_profile
4. Remove the $PATH pointing to old node version, in my case it was /usr/local/bin/node/@node8
5. Add & save this to $PATH instead "export PATH=$PATH:/usr/local/git/bin:/usr/local/bin"
6. Close all applications using node (terminal, simulator, browser expo etc)
7. restart terminal and check node --version

It appears the proper way to resolve this issue is to run

 pip install --upgrade virtualenv

after you have upgraded python with Homebrew.

This should be a general procedure for any formula that installs something like python, which has it's own package management system. When you install brew install python, you install python and pip and easy_install and virtualenv and so on. So, if those tools can be self-updated, it's best to try to do so before looking to Homebrew as the source of problems.

For large text, the full text index is much faster. But you can full text index varchar(max)as well.

My example

private options = new RequestOptions({headers: new Headers({'Content-Type': 'application/json'})});

My method

  getUserByName(name: string): Observable<MyObject[]> {
    //set request params
    let params: URLSearchParams = new URLSearchParams();
    params.set("name", name);
    //params.set("surname", surname); for more params
    this.options.search = params;

    let url = "http://localhost:8080/test/user/";
    console.log("url: ", url);

    return this.http.get(url, this.options)
      .map((resp: Response) => resp.json() as MyObject[])
      .catch(this.handleError);
  }

  private handleError(err) {
    console.log(err);
    return Observable.throw(err || 'Server error');
  }

in my component

  userList: User[] = [];
  this.userService.getUserByName(this.userName).subscribe(users => {
      this.userList = users;
    });

By postman

http://localhost:8080/test/user/?name=Ethem

I was searching how to do something similar in WPF and I got this solution:

<ItemsControl ItemsSource="{Binding MyItems,Mode=OneWay}">
<ItemsControl.ItemsPanel>
    <ItemsPanelTemplate>
        <StackPanel Orientation="Vertical" />
    </ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
    <DataTemplate>
        <RadioButton 
            Content="{Binding}" 
            Command="{Binding Path=DataContext.CustomCommand, 
                        RelativeSource={RelativeSource Mode=FindAncestor,      
                        AncestorType={x:Type ItemsControl}} }"
            CommandParameter="{Binding}" />
    </DataTemplate>
</ItemsControl.ItemTemplate>

I hope this works for somebody else. I have a data context which is set automatically to the ItemsControls, and this data context has two properties: MyItems -which is a collection-, and one command 'CustomCommand'. Because of the ItemTemplate is using a DataTemplate, the DataContext of upper levels is not directly accessible. Then the workaround to get the DC of the parent is use a relative path and filter by ItemsControl type.

<a href="javascript:alert('Hello');"></a>

is just shorthand for:

<a href="" onclick="alert('Hello'); return false;"></a>

You may also find a global .gitignore directly at the ~ path if you haven't created it in your folder project. This file is taken into account by all your .git projects.

Exit code at one point. That provides better readability to code. Adding return statements (Multiple exits) in between will make debugging difficult .

\tag also works in align*. Example:

\begin{align*}
  a(x)^{2} &= bx\tag{1}\\ 
  a(x)^{2} &= b\tag{2}\\ 
  ax &= b\tag{3}\\ 
  a(x)^{2}+bx &= c\tag{4}\\ 
  a(x)^{2}+c &= bx\tag{5}\\ 
  a(x)^{2} &= bx+c\tag{6}\\ \\ 
  Where\quad a, b, c \, \in N
\end{align*}

Output:

I had a similar issue recently while working on recursion and nested lists. I declared:

print(r_sum([1,2,3[1,2,3],]))

instead of

print(r_sum([1,2,3,[1,2,3],]))

Note the comma after the number 3

It sounds like you may be having trouble with SSH-Agent itself. I would try troubleshooting that.

1) Did you do ssh-add to add your key to SSH?

2) Are you closing the terminal window between uses, because if you close the window you will have to enter the password again when you reopen it.

I tried so many different things and finally found what worked best for me was simply adding in padding-right: 28px;

I played around with the padding to get the right amount to evenly space the items.

isinstance(o, str)

Link to docs

Overload a function:

unsigned int rotate_right(unsigned int x)
{
 return (x>>1 | (x&1?0x80000000:0))
}

unsigned short rotate_right(unsigned short x) { /* etc. */ }

I tried the above solutions and I was still having difficulties. I had other files staged with two files that were deleted accidentally.

To undo the two deleted files I had to unstage all of the files:

git reset HEAD .

At that point I was able to do the checkout of the deleted items:

git checkout -- WorkingFolder/FileName.ext

Finally I was able to restage the rest of the files and continue with my commit.

360 degrees is 2*PI radians

You can find the conversion formulas at: http://en.wikipedia.org/wiki/Radian#Conversion_between_radians_and_degrees.

Run this Query to get the name

SELECT @@SERVERNAME

font-size:35px;

So like this:

<html>
  <tr>
  <td style="padding-left:5px;padding-bottom:3px;"> 
    <strong style="font-size:35px;">Datum:</strong>
    <br/>
    November 2010 
  </td>
  </tr>
</html>

Although inline styles are a bad practice and you should class things. Also you should use a <strong></strong> tag instead of <b></b>

Update

As of jQuery 3.0, the new syntax is just .on:

see this answer here and the code:

$('iframe').on('load', function() {
    // do stuff 
});

GROUP BY DATE_FORMAT(record_date, '%Y%m')

Note (primarily, to potential downvoters). Presently, this may not be as efficient as other suggestions. Still, I leave it as an alternative, and a one, too, that can serve in seeing how faster other solutions are. (For you can't really tell fast from slow until you see the difference.) Also, as time goes on, changes could be made to MySQL's engine with regard to optimisation so as to make this solution, at some (perhaps, not so distant) point in future, to become quite comparable in efficiency with most others.

I'm very thoroughly investigating the matter of accuracy/rssi/proximity with iBeacons and I really really think that all the resources in the Internet (blogs, posts in StackOverflow) get it wrong.

davidgyoung (accepted answer, > 100 upvotes) says:

Note that the term "accuracy" here is iOS speak for distance in meters.

Actually, most people say this but I have no idea why! Documentation makes it very very clear that CLBeacon.proximity:

Indicates the one sigma horizontal accuracy in meters. Use this property to differentiate between beacons with the same proximity value. Do not use it to identify a precise location for the beacon. Accuracy values may fluctuate due to RF interference.

Let me repeat: one sigma accuracy in meters. All 10 top pages in google on the subject has term "one sigma" only in quotation from docs, but none of them analyses the term, which is core to understand this.

Very important is to explain what is actually one sigma accuracy. Following URLs to start with: http://en.wikipedia.org/wiki/Standard_error, http://en.wikipedia.org/wiki/Uncertainty

In physical world, when you make some measurement, you always get different results (because of noise, distortion, etc) and very often results form Gaussian distribution. There are two main parameters describing Gaussian curve:

1. mean (which is easy to understand, it's value for which peak of the curve occurs).
2. standard deviation, which says how wide or narrow the curve is. The narrower curve, the better accuracy, because all results are close to each other. If curve is wide and not steep, then it means that measurements of the same phenomenon differ very much from each other, so measurement has a bad quality.

one sigma is another way to describe how narrow/wide is gaussian curve.
It simply says that if mean of measurement is X, and one sigma is s, then 68% of all measurements will be between X - s and X + s.

Example. We measure distance and get a gaussian distribution as a result. The mean is 10m. If s is 4m, then it means that 68% of measurements were between 6m and 14m.

When we measure distance with beacons, we get RSSI and 1-meter calibration value, which allow us to measure distance in meters. But every measurement gives different values, which form gaussian curve. And one sigma (and accuracy) is accuracy of the measurement, not distance!

It may be misleading, because when we move beacon further away, one sigma actually increases because signal is worse. But with different beacon power-levels we can get totally different accuracy values without actually changing distance. The higher power, the less error.

There is a blog post which thoroughly analyses the matter: http://blog.shinetech.com/2014/02/17/the-beacon-experiments-low-energy-bluetooth-devices-in-action/

Author has a hypothesis that accuracy is actually distance. He claims that beacons from Kontakt.io are faulty beacuse when he increased power to the max value, accuracy value was very small for 1, 5 and even 15 meters. Before increasing power, accuracy was quite close to the distance values. I personally think that it's correct, because the higher power level, the less impact of interference. And it's strange why Estimote beacons don't behave this way.

I'm not saying I'm 100% right, but apart from being iOS developer I have degree in wireless electronics and I think that we shouldn't ignore "one sigma" term from docs and I would like to start discussion about it.

It may be possible that Apple's algorithm for accuracy just collects recent measurements and analyses the gaussian distribution of them. And that's how it sets accuracy. I wouldn't exclude possibility that they use info form accelerometer to detect whether user is moving (and how fast) in order to reset the previous distribution distance values because they have certainly changed.

UPDATE: Turned my solution into a stand-alone python script.

This solution has saved me more than once. Hopefully others find it useful. This python script will find any jupyter kernel using more than cpu_threshold CPU and prompts the user to send a SIGINT to the kernel (KeyboardInterrupt). It will keep sending SIGINT until the kernel's cpu usage goes below cpu_threshold. If there are multiple misbehaving kernels it will prompt the user to interrupt each of them (ordered by highest CPU usage to lowest). A big thanks goes to gcbeltramini for writing code to find the name of a jupyter kernel using the jupyter api. This script was tested on MACOS with python3 and requires jupyter notebook, requests, json and psutil.

Put the script in your home directory and then usage looks like:

python ~/interrupt_bad_kernels.py
Interrupt kernel chews cpu.ipynb; PID: 57588; CPU: 2.3%? (y/n) y

Script code below:

from os import getpid, kill

The standard Pinterest button code (which you can generate here), is an <a> tag wrapping an <img> of the Pinterest button.

If you don't include the pinit.js script on your page, this <a> tag will work "as-is". You could improve the experience by registering your own click handler on these tags that opens a new window with appropriate dimensions, or at least adding target="_blank" to the tag to make it open clicks in a new window.

The tag syntax would look like:

<a href="http://pinterest.com/pin/create/button/?url={URI-encoded URL of the page to pin}&media={URI-encoded URL of the image to pin}&description={optional URI-encoded description}" class="pin-it-button" count-layout="horizontal">
    <img border="0" src="//assets.pinterest.com/images/PinExt.png" title="Pin It" />
</a>

If using the JavaScript versions of sharing buttons are ruining your page load times, you can improve your site by using asynchronous loading methods. For an example of doing this with the Pinterest button, check out my GitHub Pinterest button project with an improved HTML5 syntax.

I like to use a rolling file appender to write the logging info to a file. My log4j properties file typically looks something like this. I prefer this way since I like to make package specific logging in case I need varying degrees of logging for different packages. Only one package is mentioned in the example.

log4j.rootLogger=warn
#Define package specific logging

You have an incompatibility between the version of ASM required by Hibernate (asm-1.5.3.jar) and the one required by Spring. But, actually, I wonder why you have asm-2.2.3.jar on your classpath (ASM is bundled in spring.jar and spring-core.jar to avoid such problems AFAIK). See HHH-2222.

if you have numbers in list, you can use map to apply str to each element:

I've just found a great tool for that need, it is called tabulate.

It prints tabular data and works with DataFrame.

from tabulate import tabulate
import pandas as pd

df = pd.DataFrame({'col_two' : [0.0001, 1e-005 , 1e-006, 1e-007],
                   'column_3' : ['ABCD', 'ABCD', 'long string', 'ABCD']})
print(tabulate(df, headers='keys', tablefmt='psql'))

+----+-----------+-------------+
|    |   col_two | column_3    |
|----+-----------+-------------|
|  0 |    0.0001 | ABCD        |
|  1 |    1e-05  | ABCD        |
|  2 |    1e-06  | long string |
|  3 |    1e-07  | ABCD        |

Note:

To suppress row indices for all types of data, pass showindex="never" or showindex=False.

I'll assume you need it for one-off things. I'll assume you're a PC developer.

Use the Stack, Luke. Use it everywhere. Don't use malloc / free for small allocations, ever.

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

#define STR_SIZE 10000

int main()
{
  char s1[] = "oppa";
  char s2[] = "gangnam";
  char s3[] = "style";

  {
    char result[STR_SIZE] = {0};
    snprintf(result, sizeof(result), "%s %s %s", s1, s2, s3);
    printf("%s\n", result);
  }
}

If 10 KB per string won't be enough, add a zero to the size and don't bother, - they'll release their stack memory at the end of the scopes anyway.

someOtherKey=someOtherValue

You can import that into webpack by a npm module called properties-reader

I found this really helpful since I'm integrating react with Java Spring framework where there is already an application.properties file. This helps me to keep all config together in one place.

1. Import that from dependencies section in package.json

"properties-reader": "0.0.16"

2. Import this module into webpack.config.js on top

const PropertiesReader = require('properties-reader');

3. Read the properties file

const appProperties = PropertiesReader('Path/to/your/properties.file')._properties;

4. Import this constant as config

externals: { 'Config': JSON.stringify(appProperties) }

5. Use it as the same way as mentioned in the accepted answer

var Config = require('Config') fetchData(Config.serverUrl + '/Enterprises/...')

Maybe my response quite late, but it covers API below and above 21 level.

To add headers we should intercept every request and create new one with required headers.

So we need to override shouldInterceptRequest method called in both cases: 1. for API until level 21; 2. for API level 21+

    webView.setWebViewClient(new WebViewClient() {

        // Handle API until level 21
        @SuppressWarnings("deprecation")
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, String url) {

            return getNewResponse(url);
        }

        // Handle API 21+
        @TargetApi(Build.VERSION_CODES.LOLLIPOP)
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {

            String url = request.getUrl().toString();

            return getNewResponse(url);
        }

        private WebResourceResponse getNewResponse(String url) {

            try {
                OkHttpClient httpClient = new OkHttpClient();

                Request request = new Request.Builder()
                        .url(url.trim())
                        .addHeader("Authorization", "YOU_AUTH_KEY") // Example header
                        .addHeader("api-key", "YOUR_API_KEY") // Example header
                        .build();

                Response response = httpClient.newCall(request).execute();

                return new WebResourceResponse(
                        null,
                        response.header("content-encoding", "utf-8"),
                        response.body().byteStream()
                );

            } catch (Exception e) {
                return null;
            }

        }
   });

If response type should be processed you could change

        return new WebResourceResponse(
                null, // <- Change here
                response.header("content-encoding", "utf-8"),
                response.body().byteStream()
        );

to

        return new WebResourceResponse(
                getMimeType(url), // <- Change here
                response.header("content-encoding", "utf-8"),
                response.body().byteStream()
        );

and add method

        private String getMimeType(String url) {
            String type = null;
            String extension = MimeTypeMap.getFileExtensionFromUrl(url);

            if (extension != null) {

                switch (extension) {
                    case "js":
                        return "text/javascript";
                    case "woff":
                        return "application/font-woff";
                    case "woff2":
                        return "application/font-woff2";
                    case "ttf":
                        return "application/x-font-ttf";
                    case "eot":
                        return "application/vnd.ms-fontobject";
                    case "svg":
                        return "image/svg+xml";
                }

                type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
            }

            return type;
        }

as much as everyone hates tables for layout, they do help with stuff like this, either using explicit table tags or using display:table-cell

<div style="width:300px; display:table">
    <label for="MyInput" style="display:table-cell; width:1px">label&nbsp;text</label>
    <input type="text" id="MyInput" style="display:table-cell; width:100%" />
</div>

I think this is worthy of a separate answer: although internally unicode data is stored as UTF-16 in Sql Server this is the Little Endian flavour, so if you're calling the database from an external system, you probably need to specify UTF-16LE.

updated() should be what you're looking for:

Called after a data change causes the virtual DOM to be re-rendered and patched.

The component’s DOM will have been updated when this hook is called, so you can perform DOM-dependent operations here.

Since the original solution is:

temp = x; y = x; x = temp;

You can make it a two liner by using:

temp = x; y = y + temp -(x=y);

Then make it a one liner by using:

x = x + y -(y=x);

Both styles are used within the Go's standard libraries.

if len(s) > 0 { ... }

can be found in the strconv package: http://golang.org/src/pkg/strconv/atoi.go

if s != "" { ... }

can be found in the encoding/json package: http://golang.org/src/pkg/encoding/json/encode.go

Both are idiomatic and are clear enough. It is more a matter of personal taste and about clarity.

Russ Cox writes in a golang-nuts thread:

The one that makes the code clear.
If I'm about to look at element x I typically write
len(s) > x, even for x == 0, but if I care about
"is it this specific string" I tend to write s == "".

It's reasonable to assume that a mature compiler will compile
len(s) == 0 and s == "" into the same, efficient code.
...

Make the code clear.

As pointed out in Timmmm's answer, the Go compiler does generate identical code in both cases.

Sets require their items to be hashable. Out of types predefined by Python only the immutable ones, such as strings, numbers, and tuples, are hashable. Mutable types, such as lists and dicts, are not hashable because a change of their contents would change the hash and break the lookup code.

Since you're sorting the list anyway, just place the duplicate removal after the list is already sorted. This is easy to implement, doesn't increase algorithmic complexity of the operation, and doesn't require changing sublists to tuples:

def uniq(lst):
    last = object()
    for item in lst:
        if item == last:
            continue
        yield item
        last = item

def sort_and_deduplicate(l):
    return list(uniq(sorted(l, reverse=True)))

While I strongly disagree with the idea of running a laravel app on shared hosting (a bad idea all around), this package would likely solve your problem. It is a package that allows you to run some artisan commands from the web. It's far from perfect, but can work for some usecases.

https://github.com/recca0120/laravel-terminal

There is no way to do this in single query. You have to search the document in first query:

If document exists:

db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } , 
                {$inc : {"items.$.price" : 1} } , 
                false , 
                true);

Else

db.bar.update( {user_id : 123456 } , 
                {$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
                false , 
                true);

No need to add condition {$ne : "my_item_two" }.

Also in multithreaded enviourment you have to be careful that only one thread can execute the second (insert case, if document did not found) at a time, otherwise duplicate embed documents will be inserted.

As said Will Wagner, in old version of jsp you should always use c:out to output dynamic text.

Moreover, using this syntax:

<c:out value="${person.name}">No name</c:out>

you can display the text "No name" when name is null.

Using str.format:

>>> array_alpha = [ 133, 53, 234, 241 ]
>>> print ''.join('{:02x}'.format(x) for x in array_alpha)
8535eaf1

or using format

>>> print ''.join(format(x, '02x') for x in array_alpha)
8535eaf1

Note: In the format statements, the 02 means it will pad with up to 2 leading 0s if necessary. This is important since [0x1, 0x1, 0x1] i.e. (0x010101) would be formatted to "111" instead of "010101"

or using bytearray with binascii.hexlify:

>>> import binascii
>>> binascii.hexlify(bytearray(array_alpha))
'8535eaf1'

Here is a benchmark of above methods in Python 3.6.1:

from timeit import timeit
import binascii

number = 10000

def using_str_format() -> str:
    return "".join("{:02x}".format(x) for x in test_obj)

def using_format() -> str:
    return "".join(format(x, "02x") for x in test_obj)

def using_hexlify() -> str:
    return binascii.hexlify(bytearray(test_obj)).decode('ascii')

def do_test():
    print("Testing with {}-byte {}:".format(len(test_obj), test_obj.__class__.__name__))
    if using_str_format() != using_format() != using_hexlify():
        raise RuntimeError("Results are not the same")

    print("Using str.format       -> " + str(timeit(using_str_format, number=number)))
    print("Using format           -> " + str(timeit(using_format, number=number)))
    print("Using binascii.hexlify -> " + str(timeit(using_hexlify, number=number)))

test_obj = bytes([i for i in range(255)])
do_test()

test_obj = bytearray([i for i in range(255)])
do_test()

Result:

Testing with 255-byte bytes:
Using str.format       -> 1.459474583090427
Using format           -> 1.5809937679100738
Using binascii.hexlify -> 0.014521426401399307
Testing with 255-byte bytearray:
Using str.format       -> 1.443447684109402
Using format           -> 1.5608712609513171
Using binascii.hexlify -> 0.014114164661833684

Methods using format do provide additional formatting options, as example separating numbers with spaces " ".join, commas ", ".join, upper-case printing "{:02X}".format(x)/format(x, "02X"), etc., but at a cost of great performance impact.

The solution above does not work in all InputBox-Cancel cases. Most notably, it does not work if you have to InputBox a Range.

For example, try the following InputBox for defining a custom range ('sRange', type:=8, requires Set + Application.InputBox) and you will get an error upon pressing Cancel:

Sub Cancel_Handler_WRONG()
Set sRange = Application.InputBox("Input custom range", _
    "Cancel-press test", Selection.Address, Type:=8)
If StrPtr(sRange) = 0 Then  'I also tried with sRange.address and vbNullString
    MsgBox ("Cancel pressed!")
    Exit Sub
End If
    MsgBox ("Your custom range is " & sRange.Address)
End Sub

The only thing that works, in this case, is an "On Error GoTo ErrorHandler" statement before the InputBox + ErrorHandler at the end:

Sub Cancel_Handler_OK()
On Error GoTo ErrorHandler
Set sRange = Application.InputBox("Input custom range", _
    "Cancel-press test", Selection.Address, Type:=8)
MsgBox ("Your custom range is " & sRange.Address)
Exit Sub
ErrorHandler:
    MsgBox ("Cancel pressed")
End Sub

So, the question is how to detect either an error or StrPtr()=0 with an If statement?

Seems like getTime is not function on above answer.

Date.parse(currentDate)/1000

Depending on the Tkinter activity, and especially when using Tkinter.after, stopping this activity with destroy() -- even by using protocol(), a button, etc. -- will disturb this activity ("while executing" error) rather than just terminate it. The best solution in almost every case is to use a flag. Here is a simple, silly example of how to use it (although I am certain that most of you don't need it! :)

from Tkinter import *

def close_window():
  global running
  running = False  # turn off while loop
  print( "Window closed")

root = Tk()
root.protocol("WM_DELETE_WINDOW", close_window)
cv = Canvas(root, width=200, height=200)
cv.pack()

running = True;
# This is an endless loop stopped only by setting 'running' to 'False'
while running: 
  for i in range(200): 
    if not running: 
        break
    cv.create_oval(i, i, i+1, i+1)
    root.update() 

This terminates graphics activity nicely. You only need to check running at the right place(s).

Not with an iterator.

For org.json.JSONArray, you can do:

for (int i = 0; i < arr.length(); i++) {
  arr.getJSONObject(i);
}

For javax.json.JsonArray, you can do:

for (int i = 0; i < arr.size(); i++) {
  arr.getJsonObject(i);
}

>>> () is ()
True
>>> 1 is 1
True
>>> (1,) == (1,)
True
>>> (1,) is (1,)
False
>>> a = (1,)
>>> b = a
>>> a is b
True

Some objects are singletons, and thus is with them is equivalent to ==. Most are not.

First of all, you should be aware of the fact that CUDA will not automagically make computations faster. On the one hand, because GPU programming is an art, and it can be very, very challenging to get it right. On the other hand, because GPUs are well-suited only for certain kinds of computations.

This may sound confusing, because you can basically compute anything on the GPU. The key point is, of course, whether you will achieve a good speedup or not. The most important classification here is whether a problem is task parallel or data parallel. The first one refers, roughly speaking, to problems where several threads are working on their own tasks, more or less independently. The second one refers to problems where many threads are all doing the same - but on different parts of the data.

The latter is the kind of problem that GPUs are good at: They have many cores, and all the cores do the same, but operate on different parts of the input data.

You mentioned that you have "simple math but with huge amount of data". Although this may sound like a perfectly data-parallel problem and thus like it was well-suited for a GPU, there is another aspect to consider: GPUs are ridiculously fast in terms of theoretical computational power (FLOPS, Floating Point Operations Per Second). But they are often throttled down by the memory bandwidth.

This leads to another classification of problems. Namely whether problems are memory bound or compute bound.

The first one refers to problems where the number of instructions that are done for each data element is low. For example, consider a parallel vector addition: You'll have to read two data elements, then perform a single addition, and then write the sum into the result vector. You will not see a speedup when doing this on the GPU, because the single addition does not compensate for the efforts of reading/writing the memory.

The second term, "compute bound", refers to problems where the number of instructions is high compared to the number of memory reads/writes. For example, consider a matrix multiplication: The number of instructions will be O(n^3) when n is the size of the matrix. In this case, one can expect that the GPU will outperform a CPU at a certain matrix size. Another example could be when many complex trigonometric computations (sine/cosine etc) are performed on "few" data elements.

As a rule of thumb: You can assume that reading/writing one data element from the "main" GPU memory has a latency of about 500 instructions....

Therefore, another key point for the performance of GPUs is data locality: If you have to read or write data (and in most cases, you will have to ;-)), then you should make sure that the data is kept as close as possible to the GPU cores. GPUs thus have certain memory areas (referred to as "local memory" or "shared memory") that usually is only a few KB in size, but particularly efficient for data that is about to be involved in a computation.

So to emphasize this again: GPU programming is an art, that is only remotely related to parallel programming on the CPU. Things like Threads in Java, with all the concurrency infrastructure like ThreadPoolExecutors, ForkJoinPools etc. might give the impression that you just have to split your work somehow and distribute it among several processors. On the GPU, you may encounter challenges on a much lower level: Occupancy, register pressure, shared memory pressure, memory coalescing ... just to name a few.

However, when you have a data-parallel, compute-bound problem to solve, the GPU is the way to go.

A general remark: Your specifically asked for CUDA. But I'd strongly recommend you to also have a look at OpenCL. It has several advantages. First of all, it's an vendor-independent, open industry standard, and there are implementations of OpenCL by AMD, Apple, Intel and NVIDIA. Additionally, there is a much broader support for OpenCL in the Java world. The only case where I'd rather settle for CUDA is when you want to use the CUDA runtime libraries, like CUFFT for FFT or CUBLAS for BLAS (Matrix/Vector operations). Although there are approaches for providing similar libraries for OpenCL, they can not directly be used from Java side, unless you create your own JNI bindings for these libraries.

You might also find it interesting to hear that in October 2012, the OpenJDK HotSpot group started the project "Sumatra": http://openjdk.java.net/projects/sumatra/ . The goal of this project is to provide GPU support directly in the JVM, with support from the JIT. The current status and first results can be seen in their mailing list at http://mail.openjdk.java.net/mailman/listinfo/sumatra-dev

However, a while ago, I collected some resources related to "Java on the GPU" in general. I'll summarize these again here, in no particular order.

(Byte)code translation and OpenCL code generation:

https://github.com/aparapi/aparapi : An open-source library that is created and actively maintained by AMD. In a special "Kernel" class, one can override a specific method which should be executed in parallel. The byte code of this method is loaded at runtime using an own bytecode reader. The code is translated into OpenCL code, which is then compiled using the OpenCL compiler. The result can then be executed on the OpenCL device, which may be a GPU or a CPU. If the compilation into OpenCL is not possible (or no OpenCL is available), the code will still be executed in parallel, using a Thread Pool.

https://github.com/pcpratts/rootbeer1 : An open-source library for converting parts of Java into CUDA programs. It offers dedicated interfaces that may be implemented to indicate that a certain class should be executed on the GPU. In contrast to Aparapi, it tries to automatically serialize the "relevant" data (that is, the complete relevant part of the object graph!) into a representation that is suitable for the GPU.

https://code.google.com/archive/p/java-gpu/ : A library for translating annotated Java code (with some limitations) into CUDA code, which is then compiled into a library that executes the code on the GPU. The Library was developed in the context of a PhD thesis, which contains profound background information about the translation process.

https://github.com/ochafik/ScalaCL : Scala bindings for OpenCL. Allows special Scala collections to be processed in parallel with OpenCL. The functions that are called on the elements of the collections can be usual Scala functions (with some limitations) which are then translated into OpenCL kernels.

Language extensions

http://www.ateji.com/px/index.html : A language extension for Java that allows parallel constructs (e.g. parallel for loops, OpenMP style) which are then executed on the GPU with OpenCL. Unfortunately, this very promising project is no longer maintained.

http://www.habanero.rice.edu/Publications.html (JCUDA) : A library that can translate special Java Code (called JCUDA code) into Java- and CUDA-C code, which can then be compiled and executed on the GPU. However, the library does not seem to be publicly available.

File file = new File(getFilePath(imageUri.getValue())); 
boolean b = file.delete();

is not working in my case.

boolean b = file.delete();                 // returns false
boolean b = file.getAbsolutePath.delete(); // returns false 

always returns false.

The issue has been resolved by using the code below:

ContentResolver contentResolver = getContentResolver();
contentResolver.delete(uriDelete, null, null);

It's called an initialization list. It initializes members before the body of the constructor executes.

I think refilling the same adapter with different data would be more or most better technique. Put this method in your Adapter class with right argument (the data list you want to display as names in my case) Call this where u update the data of list with updated list (names in my case)

public void refill(ArrayList<BeanDatabase> names) {
    list.clear();
    list.addAll(names);
    list.notifyDataSetChanged();
}

If you change the adapter or set the adapter again and again on when the list updates, then force close error would surely cause problems at some point. (Error:List data been updated but adapter doesn't notify the List View)

You do realize this is the default behavior, right? if you add /something the results would be different.

you can do a number of things to prevent default behavior.

href="#":

Will do nothing but anchor - not the best solution since it may jump to page top.

<a href="#">

href="javascript:void(0);"

Will do nothing at all and is perfectly legit.

<a href="javascript:void(0);"></a>

href="your-actual-intended-link" (Best)

obviously the best.

<a href="<your-actual-intended-link>"></a>

If you don't want an a tag to go somewhere, why use an a tag at all?

Another point to keep in mind, be sure the referenced dlls are not installed in the GAC. After testing, I installed my dlls into the GAC to do system level testing. Later, when I had to debug my code again, I couldn't step into the referenced assemblies until I deleted them from the GAC.

in your setChilds, you might want to try looping thru the list and doing something like

child.parent = this;

you also should set up the cascade on the parent to the appropriate values.

what about es6 way?

arr2 = [...arr1];

Assertions are not necessary for this. \S should work by itself as it matches any non-whitespace.

after 5 long years I'm sure not much attention is going to be received for this answer, But still to make all options complete, here is the one with data.table

library(data.table)
setDT(df)[ , list(mean_gr = mean(dt), sum_gr = sum(dt)) , by = .(group)]
#   group mean_gr sum_gr
#1:     A      61    244
#2:     B      66    396
#3:     C      68    408
#4:     D      61    488

I just replaced the swt.jar in my package with the 64bit version and it worked straight away. No need to recompile the whole package, just replace the swt.jar file and make sure your application manifest includes it.

There would be another way to do this:

var begin = moment().format("YYYY-MM-01");
var end = moment().format("YYYY-MM-") + moment().daysInMonth();

Please try the following code

Uri.fromFile(new File("/sdcard/sample.jpg"))

Class<?> cls = Class.forName(className);

But your className should be fully-qualified - i.e. com.mycompany.MyClass

I know this is, very, old question, and I have similar situation few days ago.

Problem was, in my table are approx. 10000 rows, so looping trough DataTable rows was very slow.

Finally, I found much faster solution, where I make copy of source DataTable with desired results, clear source DataTable and merge results from temporary DataTable into source one.

note : instead search for Joe in DataRow called name You have to search for all records whose not have name Joe (little opposite way of searching)

There is example (vb.net) :

'Copy all rows into tmpTable whose not contain Joe in name DataRow
Dim tmpTable As DataTable = drPerson.Select("name<>'Joe'").CopyToTable
'Clear source DataTable, in Your case dtPerson
dtPerson.Clear()
'merge tmpTable into dtPerson (rows whose name not contain Joe)
dtPerson.Merge(tmpTable)
tmpTable = Nothing

I hope so this shorter solution will help someone.

There is c# code (not sure is it correct because I used online converter :( ):

//Copy all rows into tmpTable whose not contain Joe in name DataRow
DataTable tmpTable = drPerson.Select("name<>'Joe'").CopyToTable;
//Clear source DataTable, in Your case dtPerson
dtPerson.Clear();
//merge tmpTable into dtPerson (rows whose name not contain Joe)
dtPerson.Merge(tmpTable);
tmpTable = null;

Of course, I used Try/Catch in case if there is no result (for example, if Your dtPerson don't contain name Joe it will throw exception), so You do nothing with Your table, it stays unchanged.

You just need to bind a variable into the directive "ng-class" and change it from the controller. Here is an example of how to do this:

var app = angular.module("ap",[]);_x000D_
_x000D_
app.controller("con",function($scope){_x000D_
  $scope.class = "red";_x000D_
  $scope.changeClass = function(){_x000D_
    if ($scope.class === "red")_x000D_
      $scope.class = "blue";_x000D_
    else_x000D_
      $scope.class = "red";_x000D_
  };_x000D_
});

.red{_x000D_
  color:red;_x000D_
}_x000D_
_x000D_
.blue{_x000D_
  color:blue;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
<body ng-app="ap" ng-controller="con">_x000D_
  <div ng-class="class">{{class}}</div>_x000D_
  <button ng-click="changeClass()">Change Class</button>    _x000D_
</body>

Here is the example working on jsFiddle

I wrote a little method to test out the basic color modes, based on answers by Erik Skoglund and others.

#outputs color table to console, regular and bold modes
def colortable
  names = %w(black red green yellow blue pink cyan white default)
  fgcodes = (30..39).to_a - [38]

  s = ''
  reg  = "\e[%d;%dm%s\e[0m"
  bold = "\e[1;%d;%dm%s\e[0m"
  puts '                       color table with these background codes:'
  puts '          40       41       42       43       44       45       46       47       49'
  names.zip(fgcodes).each {|name,fg|
    s = "#{fg}"
    puts "%7s "%name + "#{reg}  #{bold}   "*9 % [fg,40,s,fg,40,s,  fg,41,s,fg,41,s,  fg,42,s,fg,42,s,  fg,43,s,fg,43,s,  
      fg,44,s,fg,44,s,  fg,45,s,fg,45,s,  fg,46,s,fg,46,s,  fg,47,s,fg,47,s,  fg,49,s,fg,49,s ]
  }
end

example output:

You are exceeding the length of int datatype. You can use UNSIGNED attribute to support that value.

SIGNED INT can support till 2147483647 and with UNSIGNED INT allows double than this. After this you still want to save data than use CHAR or VARCHAR with length 10

you can use

df.describe() 

you will get basic statistics of the dataframe and to get mean of specific column you can use

df["columnname"].mean()

mToolbar.setNavigationIcon(R.mipmap.ic_launcher);
mToolbar.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.ic_menu));

Semver

<major>.<minor>.<patch>-beta.<beta> == 1.2.3-beta.2

• Use npm semver calculator for testing. Although the explanations for ^ (include everything greater than a particular version in the same major range) and ~ (include everything greater than a particular version in the same minor range) aren't a 100% correct, the calculator seems to work fine.
• Alternatively, use SemVer Check instead, which doesn't require you to pick a package and also offers explanations.

Allow or disallow changes

• Pin version: 1.2.3.
• Use ^ (like head). Allows updates at the second non-zero level from the left: ^0.2.3 means 0.2.3 <= v < 0.3.
• Use ~ (like tail). Generally freeze right-most level or set zero if omitted:
• ~1 means 1.0.0 <= v < 2.0.0
• ~1.2 means 1.2.0 <= v < 1.3.0.
• ~1.2.4 means 1.2.4 <= v < 1.3.0.
• Ommit right-most level: 0.2 means 0.2 <= v < 1. Differs from ~ because:
  • Starting omitted level version is always 0
  • You can set starting major version without specifying sublevels.

All (hopefully) possibilities

Set starting major-level and allow updates upward

*  or "(empty string)   any version
1                         v >= 1

Freeze major-level

~0 (0)            0.0 <= v < 1
0.2               0.2 <= v < 1          // Can't do that with ^ or ~ 
~1 (1, ^1)        1 <= v < 2
^1.2              1.2 <= v < 2
^1.2.3            1.2.3 <= v < 2
^1.2.3-beta.4     1.2.3-beta.4 <= v < 2

Freeze minor-level

^0.0 (0.0)        0 <= v < 0.1
~0.2              0.2 <= v < 0.3
~1.2              1.2 <= v < 1.3
~0.2.3 (^0.2.3)   0.2.3 <= v < 0.3
~1.2.3            1.2.3 <= v < 1.3

Freeze patch-level

~1.2.3-beta.4     1.2.3-beta.4 <= v < 1.2.4 (only beta or pr allowed)
^0.0.3-beta       0.0.3-beta.0 <= v < 0.0.4 or 0.0.3-pr.0 <= v < 0.0.4 (only beta or pr allowed)
^0.0.3-beta.4     0.0.3-beta.4 <= v < 0.0.4 or 0.0.3-pr.4 <= v < 0.0.4 (only beta or pr allowed)

Disallow updates

1.2.3             1.2.3
^0.0.3 (0.0.3)    0.0.3

Notice: Missing major, minor, patch or specifying beta without number, is the same as any for the missing level.

Notice: When you install a package which has 0 as major level, the update will only install new beta/pr level version! That's because npm sets ^ as default in package.json and when installed version is like 0.1.3, it freezes all major/minor/patch levels.

I've frequently used this pattern to extend the core behavior of Ruby to make it easier to deal with converting arbitrary data types to boolean values, which makes it really easy to deal with varying URL parameters, etc.

class String
  def to_boolean
    ActiveRecord::Type::Boolean.new.cast(self)
  end
end

class NilClass
  def to_boolean
    false
  end
end

class TrueClass
  def to_boolean
    true
  end

  def to_i
    1
  end
end

class FalseClass
  def to_boolean
    false
  end

  def to_i
    0
  end
end

class Integer
  def to_boolean
    to_s.to_boolean
  end
end

So let's say you have a parameter foo which can be:

• an integer (0 is false, all others are true)
• a true boolean (true/false)
• a string ("true", "false", "0", "1", "TRUE", "FALSE")
• nil

Instead of using a bunch of conditionals, you can just call foo.to_boolean and it will do the rest of the magic for you.

In Rails, I add this to an initializer named core_ext.rb in nearly all of my projects since this pattern is so common.

## EXAMPLES

nil.to_boolean     == false
true.to_boolean    == true
false.to_boolean   == false
0.to_boolean       == false
1.to_boolean       == true
99.to_boolean      == true
"true".to_boolean  == true
"foo".to_boolean   == true
"false".to_boolean == false
"TRUE".to_boolean  == true
"FALSE".to_boolean == false
"0".to_boolean     == false
"1".to_boolean     == true
true.to_i          == 1
false.to_i         == 0

You can do this:

var $html = $('<iframe width="854" height="480" src="http://www.youtube.com/embed/gYKqrjq5IjU?feature=oembed" frameborder="0" allowfullscreen></iframe>');    _x000D_
var str = $html.prop('outerHTML');_x000D_
console.log(str);

FIDDLE DEMO

$a | sort -unique

This works with case-insensitive, therefore removing duplicates strings with differing cases. Solved my problem.

$ServerList = @(
    "FS3",
    "HQ2",
    "hq2"
) | sort -Unique

$ServerList

The above outputs:

FS3
HQ2

dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells;
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.NotSet;
}

When you use Acrobat 8, or 9, select "enable usage rights" from the Advanced menu. This adds about 20 kb to the pdf.

The other possibility is to use CutePDF Pro, add a submit button and have the XFDF data submitted to your self as an email or to a web server. The XFDF data can then reload the original PDF with your data.

If you're using a module, that means you're bringing all the methods into your class. If you extend a class with a module, that means you're "bringing in" the module's methods as class methods. If you include a class with a module, that means you're "bringing in" the module's methods as instance methods.

EX:

 module A
   def say
     puts "this is module A"
   end
 end

 class B
   include A
 end

 class C
   extend A
 end

B.say => undefined method 'say' for B:Class

B.new.say => this is module A

C.say => this is module A

C.new.say => undefined method 'say' for C:Class

I finally managed to create a query that does exactly what i wanted to have:

}

In pseudo-SQL:

SELECT * FROM /test/object
WHERE 
    ((name=foo AND name=bar) OR (info=foo AND info=bar))
AND state=1

Please keep in mind that it depends on your document field analysis and mappings how name=foo is internally handled. This can vary from a fuzzy to strict behavior.

"minimum_should_match": 1 says, that at least one of the should statements must be true.

This statements means that whenever there is a document in the resultset that contains has_image:1 it is boosted by factor 100. This changes result ordering.

"should": [
  {
    "match": {
      "has_image": {
        "query": 1,
        "boost": 100
      }
    }
   }
 ]

Have fun guys :)

this command enables you to look all stashed changes.

git stash list

Here is the following command use it to clear all of your stashed Changes

git stash clear

Now if you want to delete one of the stashed changes from stash area

git stash drop stash@{index}   // here index will be shown after getting stash list.

Note : git stash list enables you to get index from stash area of git.

showInventory(player); is passing a type as parameter. That's illegal, you need to pass an object.

For example, something like:

player p;
showInventory(p);  

I'm guessing you have something like this:

int main()
{
   player player;
   toDo();
}

which is awful. First, don't name the object the same as your type. Second, in order for the object to be visible inside the function, you'll need to pass it as parameter:

int main()
{
   player p;
   toDo(p);
}

and

std::string toDo(player& p) 
{
    //....
    showInventory(p);
    //....
}

I had a similar problem with another library and the reason why it didn't found it, was that I didn't run the make install (after running ./configure and make) for that library. The make install may require root privileges (in this case use: sudo make install). After running the make install you should have the so files in the correct folder, i.e. here /usr/local/lib and not in the folder mentioned by you.

First of all, I don't think that your intention is to actually use punctuation as delimiters in the split functions. Your description suggests that you simply want to eliminate punctuation from the resultant strings.

I come across this pretty frequently, and my usual solution doesn't require re.

One-liner lambda function w/ list comprehension:

(requires import string):

split_without_punc = lambda text : [word.strip(string.punctuation) for word in 
    text.split() if word.strip(string.punctuation) != '']

# Call function
split_without_punc("Hey, you -- what are you doing?!")
# returns ['Hey', 'you', 'what', 'are', 'you', 'doing']

Function (traditional)

As a traditional function, this is still only two lines with a list comprehension (in addition to import string):

def split_without_punctuation2(text):

    # Split by whitespace
    words = text.split()

    # Strip punctuation from each word
    return [word.strip(ignore) for word in words if word.strip(ignore) != '']

split_without_punctuation2("Hey, you -- what are you doing?!")
# returns ['Hey', 'you', 'what', 'are', 'you', 'doing']

It will also naturally leave contractions and hyphenated words intact. You can always use text.replace("-", " ") to turn hyphens into spaces before the split.

General Function w/o Lambda or List Comprehension

For a more general solution (where you can specify the characters to eliminate), and without a list comprehension, you get:

def split_without(text: str, ignore: str) -> list:

    # Split by whitespace
    split_string = text.split()

    # Strip any characters in the ignore string, and ignore empty strings
    words = []
    for word in split_string:
        word = word.strip(ignore)
        if word != '':
            words.append(word)

    return words

# Situation-specific call to general function
import string
final_text = split_without("Hey, you - what are you doing?!", string.punctuation)
# returns ['Hey', 'you', 'what', 'are', 'you', 'doing']

Of course, you can always generalize the lambda function to any specified string of characters as well.

I solved this by putting two CardViews in a RelativeLayout. One with background of the border color and the other one with the image. (or whatever you wish to use)

Note the margin added to top and start for the second CardView. In my case I decided to use a 2dp thick border.

            <android.support.v7.widget.CardView
            android:id="@+id/user_thumb_rounded_background"
            android:layout_width="36dp"
            android:layout_height="36dp"
            app:cardCornerRadius="18dp"
            android:layout_marginEnd="6dp">

            <ImageView
                android:id="@+id/user_thumb_background"
                android:background="@color/colorPrimaryDark"
                android:layout_width="36dp"
                android:layout_height="36dp" />

        </android.support.v7.widget.CardView>

        <android.support.v7.widget.CardView
            android:id="@+id/user_thumb_rounded"
            android:layout_width="32dp"

            app:cardCornerRadius="16dp"
            android:layout_marginTop="2dp"
            android:layout_marginStart="2dp"
            android:layout_marginEnd="6dp">

        <ImageView
            android:id="@+id/user_thumb"
            android:src="@drawable/default_profile"
            android:layout_width="32dp"

If you just need to make a simple call to a REST service from java you use something along these line

import java.io.*;

public class Rest {

        URL url = new URL(INSERT_HERE_YOUR_URL);
        String query = INSERT_HERE_YOUR_URL_PARAMETERS;

        //make connection
        URLConnection urlc = url.openConnection();

        //use post mode
        urlc.setDoOutput(true);

        //send query
        PrintStream ps = new PrintStream(urlc.getOutputStream());

Using an element-wise logical or and setting the take_last argument of the pandas duplicated method to both True and False you can obtain a set from your dataframe that includes all of the duplicates.

df_bigdata_duplicates = 
    df_bigdata[df_bigdata.duplicated(cols='ID', take_last=False) |
               df_bigdata.duplicated(cols='ID', take_last=True)
              ]

You need to add some arguments. Also, instancing and opening can be put in one line:

fstream file("test.txt", fstream::in | fstream::out | fstream::trunc);

SELECT  CASE WHEN SERVERPROPERTY('EditionID') = -1253826760 THEN 'Desktop'
         WHEN SERVERPROPERTY('EditionID') = -1592396055 THEN 'Express'
         WHEN SERVERPROPERTY('EditionID') = -1534726760 THEN 'Standard'
         WHEN SERVERPROPERTY('EditionID') = 1333529388 THEN 'Workgroup'
         WHEN SERVERPROPERTY('EditionID') = 1804890536 THEN 'Enterprise'
         WHEN SERVERPROPERTY('EditionID') = -323382091 THEN 'Personal'
         WHEN SERVERPROPERTY('EditionID') = -2117995310  THEN 'Developer'
         WHEN SERVERPROPERTY('EditionID') = 610778273  THEN 'Windows Embedded SQL'
         WHEN SERVERPROPERTY('EditionID') = 4161255391   THEN 'Express with Advanced Services'
    END AS 'Edition'; 

I knew that SQL was bad at string manipulation, but I didn't think it would be this difficult. Here's a simple function to strip out all the numbers from a string. There would be better ways to do this, but this is a start.

My challenge to readers: Can you make this more efficient? What about using recursion?

The simple solution is to avoid creating an array before piping to Out-File. Rule #1 of PowerShell is that the comma is a special delimiter, and the default behavior is to create an array. Concatenation is done like this.

$computer + "," + $Speed + "," + $Regcheck | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200

This creates an array of three items.

$computer,$Speed,$Regcheck
FYKJ
100
YES

vs. concatenation of three items separated by commas.

$computer + "," + $Speed + "," + $Regcheck
FYKJ,100,YES

The best solution I have found is in the blog post Using Newer Version(s) of .NET with PowerShell. This allows powershell.exe to run with .NET 4 assemblies.

Simply modify (or create) $pshome\powershell.exe.config so that it contains the following:

<?xml version="1.0"?> 
<configuration> 
    <startup useLegacyV2RuntimeActivationPolicy="true"> 
        <supportedRuntime version="v4.0.30319"/> 
        <supportedRuntime version="v2.0.50727"/> 
    </startup> 
</configuration> 

Additional, quick setup notes:

Locations and files are somewhat platform dependent; however will give you an inline gist of how to make the solution work for you.

• You can find PowerShell's location on your computer by executing cd $pshome in the Powershell window (doesn't work from DOS prompt).
  • Path will be something like (example) C:\Windows\System32\WindowsPowerShell\v1.0\
• The filename to put configuration in is: powershell.exe.config if your PowerShell.exe is being executed (create the config file if need be).
  • If PowerShellISE.Exe is running then you need to create its companion config file as PowerShellISE.Exe.config

This would be work very fine

<a href="<%:Url.Action("Edit","Account",new {  id=item.UserId }) %>"><img src="../../Content/ThemeNew/images/edit_notes_delete11.png" alt="Edit" width="25px" height="25px" /></a>

You must be prompted in your s4 screen to authorize that computer. You can tell it to remember it. This is for security reasons, occurring in Android 4.4+

any():

if any(t < 0 for t in x):
    # do something

Also, if you're going to use "True in ...", make it a generator expression so it doesn't take O(n) memory:

if True in (t < 0 for t in x):

Just another way to fix this up on Heroku: Make sure your Rakefile is committed and pushed.

To expand on Ryan's answer, when you are declaring variables (using Dim) you can cheat a little bit by using the predictive text feature in the VBE, as in the image below.

If it shows up in that list, then you can assign an object of that type to a variable. So not just a Worksheet, as Ryan pointed out, but also a Chart, Range, Workbook, Series and on and on.

You set that variable equal to the object you want to manipulate and then you can call methods, pass it to functions, etc, just like Ryan pointed out for this example. You might run into a couple snags when it comes to collections vs objects (Chart or Charts, Range or Ranges, etc) but with trial and error you'll get it for sure.

Use the following steps to load .CSS file its very simple.

<link rel="stylesheet" href="path_here.css">

note: 1--> don't forget to write "stylesheet" in rel attribute. 2--> use correct path e.g: D:\folder1\forlder2\folder3\file.css"

Now where ever directory you are in, you can load your .css file exactly path you mention.

In order to stay on the same page on submit you can leave action empty (action="") into the form tag, or leave it out altogether.

For the message, create a variable ($message = "Success! You entered: ".$input;") and then echo the variable at the place in the page where you want the message to appear with <?php echo $message; ?>.

Like this:

<?php
$message = "";
if(isset($_POST['SubmitButton'])){ //check if form was submitted
  $input = $_POST['inputText']; //get input text
  $message = "Success! You entered: ".$input;
}    
?>

<html>
<body>    
<form action="" method="post">
<?php echo $message; ?>
  <input type="text" name="inputText"/>
  <input type="submit" name="SubmitButton"/>
</form>    
</body>
</html>

I wrote an updated version of Kees C. Bakker's answer:

const hasVerticalScroll = (node) => {
  if (!node) {
    if (window.innerHeight) {
      return document.body.offsetHeight > window.innerHeight
    }
    return (document.documentElement.scrollHeight > document.documentElement.offsetHeight)
      || (document.body.scrollHeight > document.body.offsetHeight)
  }
  return node.scrollHeight > node.offsetHeight
}

if (hasVerticalScroll(document.querySelector('body'))) {
  this.props.handleDisableDownScrollerButton()
}

The function returns true or false depending whether the page has a vertical scrollbar or not.

For example:

const hasVScroll = hasVerticalScroll(document.querySelector('body'))

if (hasVScroll) {
  console.log('HAS SCROLL', hasVScroll)
}

Your PATH might not setup. Go to terminal and type:

echo 'export PATH="/usr/local/mysql/bin:$PATH"' >> ~/.bash_profile

Essentially, this allows you to access mysql from anywhere.

Type cat .bash_profile to check the PATH has been setup.

Check mysql version now: mysql --version

If this still doesn't work, close the terminal and reopen. Check the version now, it should work. Good luck!

I think you should be able to develop applications using the visual studio development web server: Start a new FaceBook application on: http://www.facebook.com/developers/. Then set the settings for the site Url and the canvas url to the running instance of your website for example:http://localhost:1062/

Here are a couple of links that should help you out on starting with FaceBook:

1. http://thinkdiff.net/facebook/graph-api-iframe-base-facebook-application-development/,
2. http://nagbaba.blogspot.com/2010/05/experiencing-facebook-javascript-sdk.html,

Hope this helps.

This indicates the linux has delivered a SIGTERM to your process. This is usually at the request of some other process (via kill()) but could also be sent by your process to itself (using raise()). This signal requests an orderly shutdown of your process.

If you need a quick cheatsheet of signal numbers, open a bash shell and:

$ kill -l
 1) SIGHUP   2) SIGINT   3) SIGQUIT  4) SIGILL
 5) SIGTRAP  6) SIGABRT  7) SIGBUS   8) SIGFPE
 9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2
13) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT
17) SIGCHLD 18) SIGCONT 19) SIGSTOP 20) SIGTSTP
21) SIGTTIN 22) SIGTTOU 23) SIGURG  24) SIGXCPU
25) SIGXFSZ 26) SIGVTALRM   27) SIGPROF 28) SIGWINCH
29) SIGIO   30) SIGPWR  31) SIGSYS  34) SIGRTMIN
35) SIGRTMIN+1  36) SIGRTMIN+2  37) SIGRTMIN+3  38) SIGRTMIN+4
39) SIGRTMIN+5  40) SIGRTMIN+6  41) SIGRTMIN+7  42) SIGRTMIN+8
43) SIGRTMIN+9  44) SIGRTMIN+10 45) SIGRTMIN+11 46) SIGRTMIN+12
47) SIGRTMIN+13 48) SIGRTMIN+14 49) SIGRTMIN+15 50) SIGRTMAX-14
51) SIGRTMAX-13 52) SIGRTMAX-12 53) SIGRTMAX-11 54) SIGRTMAX-10
55) SIGRTMAX-9  56) SIGRTMAX-8  57) SIGRTMAX-7  58) SIGRTMAX-6
59) SIGRTMAX-5  60) SIGRTMAX-4  61) SIGRTMAX-3  62) SIGRTMAX-2
63) SIGRTMAX-1  64) SIGRTMAX    

You can determine the sender by using an appropriate signal handler like:

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

void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
  fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
      info->si_pid);
  exit(0);
}

int main (void)
{
  struct sigaction action = {
    .sa_handler = NULL,
    .sa_sigaction = sigterm_handler,
    .sa_mask = 0,
    .sa_flags = SA_SIGINFO,
    .sa_restorer = NULL
  };

  sigaction(SIGTERM, &action, NULL);
  sleep(60);

  return 0;
}

Notice that the signal handler also includes a call to exit(). It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

console.log('Hello, \n' + 
            'Text under your Header\n' + 
            '-------------------------\n' + 
            'More Text\n' +
            'Moree Text\n' +
            'Moooooer Text\n' );

This works great for me for text only, and easy on the eye.

in Swift 3.0

yourView.backgroundColor = UIColor.black.withAlphaComponent(0.5)

This works for me in xcode 8.2.

It may helps you.

getResourceAsStream() look inside of your resource folder. So the fil shold be placed inside of the defined resource-folder i.e if the file reside in /src/main/resources/properties --> then the path should be /properties/yourFilename.

getClass.getResourceAsStream(/properties/yourFilename)

Following the useful comments, I've completely rebuilt the date formatter. Usage is supposed to:

• Be short (one liner)
• Represent disposable objects (time zone, format) as Strings
• Support useful, sortable ISO formats and the legacy format from the box

If you consider this code useful, I may publish the source and a JAR in github.

Usage

// The problem - not UTC
Date.toString()                      
"Tue Jul 03 14:54:24 IDT 2012"

// ISO format, now
PrettyDate.now()        
"2012-07-03T11:54:24.256 UTC"

// ISO format, specific date
PrettyDate.toString(new Date())         
"2012-07-03T11:54:24.256 UTC"

// Legacy format, specific date
PrettyDate.toLegacyString(new Date())   
"Tue Jul 03 11:54:24 UTC 2012"

// ISO, specific date and time zone
PrettyDate.toString(moonLandingDate, "yyyy-MM-dd hh:mm:ss zzz", "CST") 
"1969-07-20 03:17:40 CDT"

// Specific format and date
PrettyDate.toString(moonLandingDate, "yyyy-MM-dd")
"1969-07-20"

// ISO, specific date
PrettyDate.toString(moonLandingDate)
"1969-07-20T20:17:40.234 UTC"

// Legacy, specific date
PrettyDate.toLegacyString(moonLandingDate)
"Wed Jul 20 08:17:40 UTC 1969"

The PHP5 version do not support in Ubuntu 18.04+ versions, so you have to do that configure manually from the source files. If you are using php-5.3.29,

# cd /usr/local/src/php-5.3.29
# ./configure --with-apxs2=/usr/local/apache/bin/apxs --with-mysql=MySQL_LOCATION/mysql --prefix=/usr/local/apache/php --with-config-file-path=/usr/local/apache/php --disable-cgi --with-zlib --with-gettext --with-gdbm --with-curl --enable-zip --with-xml --with-json --enable-shmop
# make
# make install

HTML5 has a built-in combo box. You create a text input and a datalist. Then you add a list attribute to the input, with a value of the id of the datalist.

Update: As of March 2019 all major browsers (now including Safari 12.1 and iOS Safari 12.3) support datalist to the level needed for this functionality. See caniuse for detailed browser support.

It looks like this:

<input type="text" list="cars" />_x000D_
<datalist id="cars">_x000D_
  <option>Volvo</option>_x000D_
  <option>Saab</option>_x000D_
  <option>Mercedes</option>_x000D_
  <option>Audi</option>_x000D_
</datalist>

The short answer is, use:

(SomeEnum[])Enum.GetValues(typeof(SomeEnum))

If you need that for a local variable, it's var allSomeEnumValues = (SomeEnum[])Enum.GetValues(typeof(SomeEnum));.

Why is the syntax like this?!

The static method GetValues was introduced back in the old .NET 1.0 days. It returns a one-dimensional array of runtime type SomeEnum[]. But since it's a non-generic method (generics was not introduced until .NET 2.0), it can't declare its return type (compile-time return type) as such.

.NET arrays do have a kind of covariance, but because SomeEnum will be a value type, and because array type covariance does not work with value types, they couldn't even declare the return type as an object[] or Enum[]. (This is different from e.g. this overload of GetCustomAttributes from .NET 1.0 which has compile-time return type object[] but actually returns an array of type SomeAttribute[] where SomeAttribute is necessarily a reference type.)

Because of this, the .NET 1.0 method had to declare its return type as System.Array. But I guarantee you it is a SomeEnum[].

Everytime you call GetValues again with the same enum type, it will have to allocate a new array and copy the values into the new array. That's because arrays might be written to (modified) by the "consumer" of the method, so they have to make a new array to be sure the values are unchanged. .NET 1.0 didn't have good read-only collections.

If you need the list of all values many different places, consider calling GetValues just once and cache the result in read-only wrapper, for example like this:

public static readonly ReadOnlyCollection<SomeEnum> AllSomeEnumValues
    = Array.AsReadOnly((SomeEnum[])Enum.GetValues(typeof(SomeEnum)));

Then you can use AllSomeEnumValues many times, and the same collection can be safely reused.

Why is it bad to use .Cast<SomeEnum>()?

A lot of other answers use .Cast<SomeEnum>(). The problem with this is that it uses the non-generic IEnumerable implementation of the Array class. This should have involved boxing each of the values into an System.Object box, and then using the Cast<> method to unbox all those values again. Luckily the .Cast<> method seems to check the runtime type of its IEnumerable parameter (the this parameter) before it starts iterating through the collection, so it isn't that bad after all. It turns out .Cast<> lets the same array instance through.

If you follow it by .ToArray() or .ToList(), as in:

Enum.GetValues(typeof(SomeEnum)).Cast<SomeEnum>().ToList() // DON'T do this

you have another problem: You create a new collection (array) when you call GetValues and then create yet a new collection (List<>) with the .ToList() call. So that's one (extra) redundant allocation of an entire collection to hold the values.

No, there isn't.

I'm pretty sure there is no way to intercept a click on the refresh button from JS, and even if there was, JS can be turned off.

You should probably step back from your X (preventing refreshing) and find a different solution to Y (whatever that might be).

Intrinsic Content Size - Pretty self-explanatory, but views with variable content are aware of how big their content is and describe their content's size through this property. Some obvious examples of views that have intrinsic content sizes are UIImageViews, UILabels, UIButtons.

Content Hugging Priority - The higher this priority is, the more a view resists growing larger than its intrinsic content size.

Content Compression Resistance Priority - The higher this priority is, the more a view resists shrinking smaller than its intrinsic content size.

Check here for more explanation: AUTO LAYOUT MAGIC: CONTENT SIZING PRIORITIES

Remember to set your filters so you are not overwhelmed by the chatty file system traffic.

Added: Filemon does not work with newer Windows versions, so you might have to use Process Monitor.

Put the entire script into a template string, with {SERVERNAME} placeholders. Then edit the string using:

SET @SQL_SCRIPT = REPLACE(@TEMPLATE, '{SERVERNAME}', @DBNAME)

and then run it with

EXECUTE (@SQL_SCRIPT)

It's hard to believe that, in the course of three years, nobody noticed that my code doesn't work!

You can't EXEC multiple batches. GO is a batch separator, not a T-SQL statement. It's necessary to build three separate strings, and then to EXEC each one after substitution.

I suppose one could do something "clever" by breaking the single template string into multiple rows by splitting on GO; I've done that in ADO.NET code.

And where did I get the word "SERVERNAME" from?

Here's some code that I just tested (and which works):

DECLARE @DBNAME VARCHAR(255)
SET @DBNAME = 'TestDB'

DECLARE @CREATE_TEMPLATE VARCHAR(MAX)
DECLARE @COMPAT_TEMPLATE VARCHAR(MAX)
DECLARE @RECOVERY_TEMPLATE VARCHAR(MAX)

SET @CREATE_TEMPLATE = 'CREATE DATABASE {DBNAME}'
SET @COMPAT_TEMPLATE='ALTER DATABASE {DBNAME} SET COMPATIBILITY_LEVEL = 90'
SET @RECOVERY_TEMPLATE='ALTER DATABASE {DBNAME} SET RECOVERY SIMPLE'

DECLARE @SQL_SCRIPT VARCHAR(MAX)

SET @SQL_SCRIPT = REPLACE(@CREATE_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@COMPAT_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@RECOVERY_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

I know the accepted answer is quite old, but there is a way to control formatting with AutoGeneratColumns :

First create a function that will trigger when a column is generated :

<DataGrid x:Name="dataGrid" AutoGeneratedColumns="dataGrid_AutoGeneratedColumns" Margin="116,62,10,10"/>

Then check if the type of the column generated is a DateTime and just change its String format to "d" to remove the time part :

private void DataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
        {
            if(YourColumn == typeof(DateTime))
            {
                e.Column.ClipboardContentBinding.StringFormat = "d";
            }
        }

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

set nocount on

create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)

insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)

declare @PersonID int
set @PersonID = 1

IF EXISTS    
    (
    SELECT 1    
    FROM Timesheet_Hours    
    WHERE Posted_Flag = 1    
        AND Staff_Id = @PersonID    
    )    
    BEGIN
        RAISERROR('Timesheets have already been posted!', 16, 1)
        ROLLBACK TRAN
    END
ELSE
    IF NOT EXISTS
        (
        SELECT 1
        FROM Timesheet_Hours
        WHERE Staff_Id = @PersonID
        )
        BEGIN
            RAISERROR('Default list has not been loaded!', 16, 1)
            ROLLBACK TRAN
        END
    ELSE
        print 'No problems here'

drop table Timesheet_Hours

If you are using the two formulas at the same time, it will not work... Here is a simple spreadsheet with it working: https://docs.google.com/spreadsheet/ccc?key=0AiOy0YDBXjt4dDJSQWg1Qlp6TEw5SzNqZENGOWgwbGc If you are still getting problems I would need to know what type of erroneous result you are getting.

For me it was a simple case of specifying the path to the 'sdk' subfolder rather than the top level folder.

In my case I needed to input

/Users/Myusername/Documents/adt-bundle-mac-x86_64-20140321/sdk

instead of

strcpy is only for C strings. For std::string you copy it like any C++ object.

std::string a = "text";
std::string b = a; // copy a into b

If you want to concatenate strings you can use the + operator:

std::string a = "text";
std::string b = "image";
a = a + b; // or a += b;

You can even do many at once:

std::string c = a + " " + b + "hello";

Although "hello" + " world" doesn't work as you might expect. You need an explicit std::string to be in there: std::string("Hello") + "world"

Unless you can get PHP to label that element with a class you are better to use jQuery.

jQuery(document).ready(function () {
  $count =  jQuery("ul li").size() - 1;
  alert($count);
  jQuery("ul li:nth-child("+$count+")").css("color","red");
});

System.IO.StreamReader myFile =
   new System.IO.StreamReader("c:\\test.txt");
string myString = myFile.ReadToEnd();

Unit testing is meant for testing the very basic functionality (the lowest level functions of the application) to be sure that your application building blocks work correctly. There is probably no formal definition of what does that exactly mean, but you should consider other kinds of testing for the bigger functionality -- see Integration testing. The unit testing framework may not be ideal for the purpose.

At first glance one really wants to use New-PSDrive supplying it credentials.

> New-PSDrive -Name P -PSProvider FileSystem -Root \\server\share -Credential domain\user

Fails!

New-PSDrive : Cannot retrieve the dynamic parameters for the cmdlet. Dynamic parameters for NewDrive cannot be retrieved for the 'FileSystem' provider. The provider does not support the use of credentials. Please perform the operation again without specifying credentials.

The documentation states that you can provide a PSCredential object but if you look closer the cmdlet does not support this yet. Maybe in the next version I guess.

Therefore you can either use net use or the WScript.Network object, calling the MapNetworkDrive function:

$net = new-object -ComObject WScript.Network
$net.MapNetworkDrive("u:", "\\server\share", $false, "domain\user", "password")

Edit for New-PSDrive in PowerShell 3.0

Apparently with newer versions of PowerShell, the New-PSDrive cmdlet works to map network shares with credentials!

New-PSDrive -Name P -PSProvider FileSystem -Root \\Server01\Public -Credential user\domain -Persist
