Using the answers above, I created a quick static method that can easily be re-used. It only aims at tinting the progress color for the activated stars. The stars that are not activated remain grey.

    public static RatingBar tintRatingBar (RatingBar ratingBar, int progressColor)if (ratingBar.getProgressDrawable() instanceof LayerDrawable) {
        LayerDrawable progressDrawable = (LayerDrawable) ratingBar.getProgressDrawable();
        Drawable drawable = progressDrawable.getDrawable(2);
        Drawable compat = DrawableCompat.wrap(drawable);
        DrawableCompat.setTint(compat, progressColor);
        Drawable[] drawables = new Drawable[3];
        drawables[2] = compat;

        drawables[0] = progressDrawable.getDrawable(0);
        drawables[1] = progressDrawable.getDrawable(1);

        LayerDrawable layerDrawable = new LayerDrawable(drawables);

        ratingBar.setProgressDrawable(layerDrawable);

        return ratingBar;
    }
    else {
        Drawable progressDrawable =  ratingBar.getProgressDrawable();
        Drawable compat = DrawableCompat.wrap(progressDrawable);
        DrawableCompat.setTint(compat, progressColor);
        ratingBar.setProgressDrawable(compat);
        return ratingBar;
    }
}

Just pass your rating bar and a Color using getResources().getColor(R.color.my_rating_color)

As you can see, I use DrawableCompat so it's backward compatible.

EDIT : This method does not work on API21 (go figure why). You end up with a NullPointerException when calling setProgressBar. I ended up disabling the whole method on API >= 21.

For API >= 21, I use SupperPuccio solution.

I ended up going totally JS-free to avoid client-side render lag. To accomplish that, I generate HTML like this:

<span class="stars" title="{value as decimal}">
    <span style="width={value/5*100}%;"/>
</span>

To help with accessibility, I even add the raw rating value in the title attribute.

In general, pickling a dict will fail unless you have only simple objects in it, like strings and integers.

However, if you use a better serializer like dill or cloudpickle, then most dictionaries can be pickled:

>>> import dill
>>> pik = dill.dumps(d)

Or if you want to save your dict to a file...

>>> with open('save.pik', 'w') as f:
...   dill.dump(globals(), f)
... 

The latter example is identical to any of the other good answers posted here (which aside from neglecting the picklability of the contents of the dict are good).

In Rails 3.2 I am using:

class ApplicationController < ActionController::Base  

  before_filter :set_p3p  

  private  
    # for IE session cookies thru iframe  
    def set_p3p  
      headers['P3P'] = 'CP="ALL DSP COR CURa ADMa DEVa OUR IND COM NAV"'  
    end  
end  

I got this from: http://dot-net-web-developer-bristol.blogspot.com/2012/04/setting-p3p-header-in-rails-session.html

If you are writing portable code, the answer is "you can't tell", the good news is that you don't need to. Your protocol should involve writing the size as (eg) "8 octets, big-endian format" (Ideally with a check that the actual size fits in 8 octets.)

Don'y forget that if you are mixing grouped (ie. SUM) fields and non-grouped fields, you need to GROUP BY one of the non-grouped fields.

Try this:

SELECT SUM(something) AS fieldname
FROM tablename
ORDER BY fieldname

OR this:

SELECT Field1, SUM(something) AS Field2
FROM tablename
GROUP BY Field1
ORDER BY Field2

And you can always do a derived query like this:

SELECT
   f1, f2
FROM
    (
        SELECT SUM(x+y) as f1, foo as F2
        FROM tablename 
        GROUP BY f2
    ) as table1
ORDER BY 
    f1

Many possibilities!

I got the same error while following an old tutorial with (not old enough) AngularJS 1.4.3. By far the simplest solution is to edit angular.js source from

function $ControllerProvider() {
  var controllers = {},
      globals = false;

to

function $ControllerProvider() {
  var controllers = {},
      globals = true;

and just follow the tutorial as-is, and the deprecated global functions just work as controllers.

One of the goals of compilers is to rule out classes of errors. Some unreachable code is there by accident, it's nice that javac rules out that class of error at compile time.

For every rule that catches erroneous code, someone will want the compiler to accept it because they know what they're doing. That's the penalty of compiler checking, and getting the balance right is one of the tricker points of language design. Even with the strictest checking there's still an infinite number of programs that can be written, so things can't be that bad.

You should write your own stream manipulator

• http://www.two-sdg.demon.co.uk/curbralan/papers/WritingStreamManipulators.html

cout << multi(5) << "whatever" << "lolcat";

Just divide the number of td to 100%. Example, you have 4 td's:

<html>
<table>
<tr>
<td style="width:25%">This is a text</td>
<td style="width:25%">This is some text, this is some text</td>
<td style="width:25%">This is another text, this is another text</td>
<td style="width:25%">This is the last text, this is the last text</td>
</tr>
</table>
</html>

We use 25% in each td to maximize the 100% space of the entire table

All javascript methods are applicable with angularjs because angularjs itself is a javascript framework so you can use indexOf() inside angular directives

<li ng-repeat="select in Items">   
         <foo ng-repeat="newin select.values">
<span ng-if="newin.label.indexOf(x) !== -1">{{newin.label}}</span></foo>
</li>
//where x is your character to be found

foreach ($array as $key => $val) {
   echo $val;
}

The accepted answer does not seem quite right to me. There is no point dragging a different version of HttpMime when one can depend on the same version of it.

compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5'
compile (group: 'org.apache.httpcomponents' , name: 'httpmime' , version: '4.3.5') {
    exclude module: 'org.apache.httpcomponents:httpclient'
}

THINGS TO REMEMBER

A lot has been said about Password encryption for PHP, most of which is very good advice, but before you even start the process of using PHP for password encryption make sure you have the following implemented or ready to be implemented.

SERVER

PORTS

No matter how good your encryption is if you don't properly secure the server that runs the PHP and DB all your efforts are worthless. Most servers function relatively the same way, they have ports assigned to allow you to access them remotely either through ftp or shell. Make sure that you change the default port of which ever remote connection you have active. By not doing this you in effect have made the attacker do one less step in accessing your system.

USERNAME

For all that is good in the world do not use the username admin, root or something similar. Also if you are on a unix based system DO NOT make the root account login accessible, it should always be sudo only.

PASSWORD

You tell your users to make good passwords to avoid getting hacked, do the same. What is the point in going through all the effort of locking your front door when you have the backdoor wide open.

DATABASE

SERVER

Ideally you want your DB and APPLICATION on separate servers. This is not always possible due to cost, but it does allow for some safety as the attacker will have to go through two steps to fully access the system.

USER

Always have your application have its own account to access the DB, and only give it the privileges it will need.

Then have a separate user account for you that is not stored anywhere on the server, not even in the application.

Like always DO NOT make this root or something similar.

PASSWORD

Follow the same guidelines as with all good passwords. Also don't reuse the same password on any SERVER or DB accounts on the same system.

PHP

PASSWORD

NEVER EVER store a password in your DB, instead store the hash and unique salt, I will explain why later.

HASHING

ONE WAY HASHING!!!!!!!, Never hash a password in a way that it can be reversed, Hashes should be one way, meaning you don't reverse them and compare them to the password, you instead hash the entered password the same way and compare the two hashes. This means that even if an attacker gets access to the DB he doesn't know what the actually password is, just its resulting hash. Which means more security for your users in the worst possible scenario.

There are a lot of good hashing functions out there (password_hash, hash, etc...) but you need to select a good algorithm for the hash to be effective. (bcrypt and ones similar to it are decent algorithms.)

When hashing speed is the key, the slower the more resistant to Brute Force attacks.

One of the most common mistakes in hashing is that hashes are not unique to the users. This is mainly because salts are not uniquely generated.

SALTING

Passwords should always be salted before hashed. Salting adds a random string to the password so similar passwords don't appear the same in the DB. However if the salt is not unique to each user (ie: you use a hard coded salt) than you pretty much have made your salt worthless. Because once an attacker figures out one password salt he has the salt for all of them.

When you create a salt make sure it is unique to the password it is salting, then store both the completed hash and salt in your DB. What this will do is make it so that an attacker will have to individually crack each salt and hash before they can gain access. This means a lot more work and time for the attacker.

USERS CREATING PASSWORDS

If the user is creating a password through the frontend that means it has to be sent to the server. This opens up a security issue because that means the unencrypted password is being sent to the server and if a attacker is able to listen and access that all your security in PHP is worthless. ALWAYS transmit the data SECURELY, this is done through SSL, but be weary even SSL is not flawless (OpenSSL's Heartbleed flaw is an example of this).

Also make the user create a secure password, it is simple and should always be done, the user will be grateful for it in the end.

Finally, no matter the security measures you take nothing is 100% secure, the more advanced the technology to protect becomes the more advanced the attacks become. But following these steps will make your site more secure and far less desirable for attackers to go after.

Here is a PHP class that creates a hash and salt for a password easily

http://git.io/mSJqpw

To make it more generic of keeping both columns in df1 and df2:

import pyspark.sql.functions as F

# Keep all columns in either df1 or df2
def outter_union(df1, df2):

    # Add missing columns to df1
    left_df = df1
    for column in set(df2.columns) - set(df1.columns):
        left_df = left_df.withColumn(column, F.lit(None))

    # Add missing columns to df2
    right_df = df2
    for column in set(df1.columns) - set(df2.columns):
        right_df = right_df.withColumn(column, F.lit(None))

    # Make sure columns are ordered the same
    return left_df.union(right_df.select(left_df.columns))

I've used this. Add a script reference to jquery on the Report.aspx page. Use the following to link up JQuery to the microsoft events. Used a little bit of Eric's suggestion for setting the overflow.

$(document).ready(function () {
    if (navigator.userAgent.toLowerCase().indexOf("webkit") >= 0) {        
        Sys.Application.add_init(function () {
            var prm = Sys.WebForms.PageRequestManager.getInstance();
            if (!prm.get_isInAsyncPostBack()) {
                prm.add_endRequest(function () {
                    var divs = $('table[id*=_fixedTable] > tbody > tr:last > td:last > div')
                    divs.each(function (idx, element) {
                        $(element).css('overflow', 'visible');
                    });
                });
            }
        });
    }
});

You can also override onContentChanged() which is among others fired when setContentView() has been called.

Use html instead of append:

$.get("banner.html", function(data){
    $(this).children("div:first").html(data);
});

Live Demo

Here is an actual implementation of what you described. I rewrote your code a bit using the latest best practices to actualize is. If you resize your browser windows under 1000px, the image's left and right side will be cropped using negative margins and it will be 300px narrower.

<style>
   .container {
      position: relative;
      width: 100%;
   }

   .bg {
      position:relative;
      z-index: 1;
      height: 100%;
      min-width: 1000px;
      max-width: 1500px;
      margin: 0 auto;
   }

   .nebula {
      width: 100%;
   }

   @media screen and (max-width: 1000px) {
      .nebula {
         width: 100%;
         overflow: hidden;
         margin: 0 -150px 0 -150px;
      }
   }
</style>

<div class="container">
   <div class="bg">
      <img src="http://i.stack.imgur.com/tFshX.jpg" class="nebula">
   </div>
</div>

I recently upgraded to Mac OS X v10.10 (Yosemite) and was having difficulty building the pg gem.

The error reported was the typical:

Using config values from /usr/local/bin/pg_config
checking for libpq-fe.h... *** extconf.rb failed ***

My solution was to gem uninstall pg and then bundle update pg to replace the gem with the latest. I did run brew update; brew upgrade after the Yosemite install to get the latest versions of packages I had installed previously.

First, you may also consider making the process of getting and validating the input a function; within that function, you can just return the value if its correct, and keep spinning in the while loop if not. This essentially obviates the problem you solved, and can usually be applied in the more general case (breaking out of multiple loops). If you absolutely must keep this structure in your code, and really don't want to deal with bookkeeping booleans...

You may also use goto in the following way (using an April Fools module from here):

#import the stuff
from goto import goto, label

while True:
    #snip: print out current state
    while True:
        ok = get_input("Is this ok? (y/n)")
        if ok == "y" or ok == "Y": goto .breakall
        if ok == "n" or ok == "N": break
    #do more processing with menus and stuff
label .breakall

I know, I know, "thou shalt not use goto" and all that, but it works well in strange cases like this.

I had this issue for days looking for answers. My error log was similar to this npm just won't install node sass The only problem was the node version. Maybe it can help some of you.

I downgraded my Node.js from 9.3.0 to 6.12.2 and run:

npm update

Most of these linker errors occur because of missing libraries.

I added the libstdc++.6.dylib in my Project->Targets->Build Phases-> Link Binary With Libraries.

That solved it for me on Xcode 6.3.2 for iOS 8.3

Cheers!

If your independent variable (RHS variable) is a factor or a character taking only one value then that type of error occurs.

Example: iris data in R

(model1 <- lm(Sepal.Length ~ Sepal.Width + Species, data=iris))

# Call:
# lm(formula = Sepal.Length ~ Sepal.Width + Species, data = iris)

# Coefficients:
#       (Intercept)        Sepal.Width  Speciesversicolor   Speciesvirginica  
#            2.2514             0.8036             1.4587             1.9468  

Now, if your data consists of only one species:

(model1 <- lm(Sepal.Length ~ Sepal.Width + Species,
              data=iris[iris$Species == "setosa", ]))
# Error in `contrasts<-`(`*tmp*`, value = contr.funs[1 + isOF[nn]]) : 
#   contrasts can be applied only to factors with 2 or more levels

If the variable is numeric (Sepal.Width) but taking only a single value say 3, then the model runs but you will get NA as coefficient of that variable as follows:

(model2 <-lm(Sepal.Length ~ Sepal.Width + Species,
             data=iris[iris$Sepal.Width == 3, ]))

# Call:
# lm(formula = Sepal.Length ~ Sepal.Width + Species, 
#    data = iris[iris$Sepal.Width == 3, ])

# Coefficients:
#       (Intercept)        Sepal.Width  Speciesversicolor   Speciesvirginica  
#             4.700                 NA              1.250              2.017

Solution: There is not enough variation in dependent variable with only one value. So, you need to drop that variable, irrespective of whether that is numeric or character or factor variable.

Updated as per comments: Since you know that the error will only occur with factor/character, you can focus only on those and see whether the length of levels of those factor variables is 1 (DROP) or greater than 1 (NODROP).

To see, whether the variable is a factor or not, use the following code:

(l <- sapply(iris, function(x) is.factor(x)))
# Sepal.Length  Sepal.Width Petal.Length  Petal.Width      Species 
#        FALSE        FALSE        FALSE        FALSE         TRUE 

Then you can get the data frame of factor variables only

m <- iris[, l]

Now, find the number of levels of factor variables, if this is one you need to drop that

ifelse(n <- sapply(m, function(x) length(levels(x))) == 1, "DROP", "NODROP")

Note: If the levels of factor variable is only one then that is the variable, you have to drop.

2015-03-30: Edited - Missing information has been added

To retrieve the current directory you can use the dynamic %cd% variable that holds the current active directory

set "curpath=%cd%"

This generates a value with a ending backslash for the root directory, and without a backslash for the rest of directories. You can force and ending backslash for any directory with

for %%a in ("%cd%\") do set "curpath=%%~fa"

Or you can use another dynamic variable: %__CD__% that will return the current active directory with an ending backslash.

Also, remember the %cd% variable can have a value directly assigned. In this case, the value returned will not be the current directory, but the assigned value. You can prevent this with a reference to the current directory

for %%a in (".\") do set "curpath=%%~fa"

Up to windows XP, the %__CD__% variable has the same behaviour. It can be overwritten by the user, but at least from windows 7 (i can't test it on Vista), any change to the %__CD__% is allowed but when the variable is read, the changed value is ignored and the correct current active directory is retrieved (note: the changed value is still visible using the set command).

BUT all the previous codes will return the current active directory, not the directory where the batch file is stored.

set "curpath=%~dp0"

It will return the directory where the batch file is stored, with an ending backslash.

BUT this will fail if in the batch file the shift command has been used

shift
echo %~dp0

As the arguments to the batch file has been shifted, the %0 reference to the current batch file is lost.

To prevent this, you can retrieve the reference to the batch file before any shifting, or change the syntax to shift /1 to ensure the shift operation will start at the first argument, not affecting the reference to the batch file. If you can not use any of this options, you can retrieve the reference to the current batch file in a call to a subroutine

@echo off
    setlocal enableextensions

    rem Destroy batch file reference
    shift
    echo batch folder is "%~dp0"

    rem Call the subroutine to get the batch folder 
    call :getBatchFolder batchFolder
    echo batch folder is "%batchFolder%"

    exit /b

:getBatchFolder returnVar
    set "%~1=%~dp0" & exit /b

This approach can also be necessary if when invoked the batch file name is quoted and a full reference is not used (read here).

You can check instance of Traversable with a simple function. This would work for all this of Iterator because Iterator extends Traversable

function canLoop($mixed) {
    return is_array($mixed) || $mixed instanceof Traversable ? true : false;
}

Try: 

SELECT EXTRACT(EPOCH FROM (timestamp_B - timestamp_A))
FROM TableA

Nested if's in Excel Are ugly:

=If(G2 < 1, .1, IF(G2 < 5,.15,if(G2 < 15,.2,if(G2 < 30,.5,if(G2 < 100,.1,1.3)))))

That should cover it.

Rely on a library: https://www.npmjs.com/package/valid-url

Don't use Taylor series. Chebyshev polynomials are both faster and more accurate, as pointed out by a couple of people above. Here is an implementation (originally from the ZX Spectrum ROM): https://albertveli.wordpress.com/2015/01/10/zx-sine/

I had something similar, and here's (an edited) version of what I ended up using successfully:

ISNULL(CONVERT(VARCHAR(50),[column name goes here],[date style goes here] ),'')

Here's why this works: If you select a date which is NULL, it will show return NULL, though it is really stored as 01/01/1900. This is why an ISNULL on the date field, while you're working with any date data type will not treat this as a NULL, as it is technically not being stored as a NULL.

However, once you convert it to a new datatype, it will convert it as a NULL, and at that point, you're ISNULL will work as you expect it to work.

I hope this works out for you as well!

~Eli

Update, nearly one year later:

I had a similar situation, where I needed the output to be of the date data-type, and my aforementioned solution didn't work (it only works if you need it displayed as a date, not be of the date data type.

If you need it to be of the date data-type, there is a way around it, and this is to nest a REPLACE within an ISNULL, the following worked for me:

Select 
    ISNULL(
        REPLACE(
            [DATE COLUMN NAME],
            '1900-01-01',
            ''
        ),
    '') AS [MeaningfulAlias]

Fundamentally if you use it as part of a business then its commercial use - so its not a matter of whether the tools are directly generating income or not rather one of if they are being used in support of income generation directly or indirectly.

To take your specific example, if the purpose of the site is to sell or promote your paid services/product then its a commercial enterprise.

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

As an alternative, you can save old data and create a new table with new parameters.

In SQL Server Management Studio: "your database" => task => generatescripts => select specific database object => "your table" => advanced => types of data to script - schema and data => generate

Personally, I did so.

Just use dynamic as the argument:

var list = new List<dynamic>();

This is not an answer, but a comment, but I could not write a comment with a formatted code, so here is the comment.

Lets say there is

public static void main(String[] args) {
  try {
    // do nothing or throw a RuntimeException
    throw new RuntimeException("test");
  } catch (Exception e) {
    System.out.println(e.getMessage());
    throw e;
  }
}

The output is

test
Exception in thread "main" java.lang.RuntimeException: test
    at MyClass.main(MyClass.java:10)

That method does not declare any "throws" Exceptions, but throws them! The trick is that the thrown exceptions are RuntimeExceptions (unchecked) that are not needed to be declared on the method. It is a bit misleading for the reader of the method, since all she sees is a "throw e;" statement but no declaration of the throws exception

Now, if we have

public static void main(String[] args) throws Exception {
  try {
    throw new Exception("test");
  } catch (Exception e) {
    System.out.println(e.getMessage());
    throw e;
  }
}

We MUST declare the "throws" exceptions in the method otherwise we get a compiler error.

I tried a simple progress bar. It is not clickable just displays the actual percentage. There's a good explication and code here: http://ruwix.com/simple-javascript-html-css-slider-progress-bar/

Compiling and running a Java application on Mac OSX, or any major operating system, is very easy. Apple includes a fully-functional Java runtime and development environment out-of-the-box with OSX, so all you have to do is write a Java program and use the built-in tools to compile and run it.

Writing Your First Program

The first step is writing a simple Java program. Open up a text editor (the built-in TextEdit app works fine), type in the following code, and save the file as "HelloWorld.java" in your home directory.

public class HelloWorld {
    public static void main(String args[]) {
        System.out.println("Hello World!");
    }
}

For example, if your username is David, save it as "/Users/David/HelloWorld.java". This simple program declares a single class called HelloWorld, with a single method called main. The main method is special in Java, because it is the method the Java runtime will attempt to call when you tell it to execute your program. Think of it as a starting point for your program. The System.out.println() method will print a line of text to the screen, "Hello World!" in this example.

Using the Compiler

Now that you have written a simple Java program, you need to compile it. Run the Terminal app, which is located in "Applications/Utilities/Terminal.app". Type the following commands into the terminal:

cd ~
javac HelloWorld.java

You just compiled your first Java application, albeit a simple one, on OSX. The process of compiling will produce a single file, called "HelloWorld.class". This file contains Java byte codes, which are the instructions that the Java Virtual Machine understands.

Running Your Program

To run the program, type the following command in the terminal.

java HelloWorld

This command will start a Java Virtual Machine and attempt to load the class called HelloWorld. Once it loads that class, it will execute the main method I mentioned earlier. You should see "Hello World!" printed in the terminal window. That's all there is to it.

As a side note, TextWrangler is just a text editor for OSX and has no bearing on this situation. You can use it as your text editor in this example, but it is certainly not necessary.

DELETE FROM on_search 
WHERE search_date < UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 180 DAY))

The only thing you should do is to set optional recursive parameter to True.

Directory.Delete("C:\MyDummyDirectory", True)

Thanks to .NET. :)

At a minimum you are going to need to know the column delimiter.

Try to login via the terminal using the following command:

mysql -u root -p

It will then prompt for your password. If this fails, then definitely the username or password is incorrect. If this works, then your database's password needs to be enclosed in quotes:

database_password: "0000"

Adding android:keepScreenOn="true" in the XML of the activity(s) you want to keep the screen on is the best option. Add that line to the main layout of the activity(s).

Something like this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:keepScreenOn="true">

...

</LinearLayout>

Consider building an Add-on that has an actual button and not using the outdated method of linking an image to a script function.

In the script editor, under the Help menu >> Welcome Screen >> link to Google Sheets Add-on - will give you sample code to use.

As an alternative, since you know the hostname, resolve the database server IP via hostname from the web server.

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

This was asked some time ago now, but based on the answer that @nacho_zona3 provided, and previous experience with fragments, the issue is that the views have not been created by the time you are trying to find them with the findViewById() method in onCreate() to fix this, move the following code:

// 1. get a reference to recyclerView
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);

// 2. set layoutManger
recyclerView.setLayoutManager(new LinearLayoutManager(this));

// this is data fro recycler view
ItemData itemsData[] = { new ItemData("Indigo",R.drawable.circle),
        new ItemData("Red",R.drawable.color_ic_launcher),
        new ItemData("Blue",R.drawable.indigo),
        new ItemData("Green",R.drawable.circle),
        new ItemData("Amber",R.drawable.color_ic_launcher),
        new ItemData("Deep Orange",R.drawable.indigo)};


// 3. create an adapter
MyAdapter mAdapter = new MyAdapter(itemsData);
// 4. set adapter
recyclerView.setAdapter(mAdapter);
// 5. set item animator to DefaultAnimator
recyclerView.setItemAnimator(new DefaultItemAnimator()); 

to your fragment's onCreateView() call. A small amount of refactoring is required because all variables and methods called from this method have to be static. The final code should look like:

 public class ColorsFragment extends Fragment {

     public ColorsFragment() {}

     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container,
         Bundle savedInstanceState) {

         View rootView = inflater.inflate(R.layout.fragment_colors, container, false);
         // 1. get a reference to recyclerView
         RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.list);

         // 2. set layoutManger
         recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

         // this is data fro recycler view
         ItemData itemsData[] = {
             new ItemData("Indigo", R.drawable.circle),
                 new ItemData("Red", R.drawable.color_ic_launcher),
                 new ItemData("Blue", R.drawable.indigo),
                 new ItemData("Green", R.drawable.circle),
                 new ItemData("Amber", R.drawable.color_ic_launcher),
                 new ItemData("Deep Orange", R.drawable.indigo)
         };


         // 3. create an adapter
         MyAdapter mAdapter = new MyAdapter(itemsData);
         // 4. set adapter
         recyclerView.setAdapter(mAdapter);
         // 5. set item animator to DefaultAnimator
         recyclerView.setItemAnimator(new DefaultItemAnimator());

         return rootView;
     }
 }

So the main thing here is that anywhere you call findViewById() you will need to use rootView.findViewById()

"When to use setAttribute vs .attribute= in JavaScript?"

A general rule is to use .attribute and check if it works on the browser.

..If it works on the browser, you're good to go.

..If it doesn't, use .setAttribute(attribute, value) instead of .attribute for that attribute.

Rinse-repeat for all attributes.

Well, if you're lazy you can simply use .setAttribute. That should work fine on most browsers. (Though browsers that support .attribute can optimize it better than .setAttribute(attribute, value).)

create a script including the following; (replace the ant and jdk paths with whatever is correct for your machine)

set  PATH=%BASEPATH%
set ANT_HOME=c:\tools\apache-ant-1.9-bin
set JAVA_HOME=c:\tools\jdk7x64
set PATH=%ANT_HOME%\bin;%JAVA_HOME%\bin;%PATH%

run it in shell.

Strings don't encapsulate color information. Are you thinking of setting the color in a console or in the GUI?

One other way could be this:

        var json_arr = {};
        json_arr["name1"] = "value1";
        json_arr["name2"] = "value2";
        json_arr["name3"] = "value3";

        var json_string = JSON.stringify(json_arr);

The correct properties are

server.servlet.path

to configure the path of the DispatcherServlet

and

server.servlet.context-path

to configure the path of the applications context below that.

You have 9 fields listed, but only 8 values. Try adding the method.

You can use easy_date to make it easy:

import date_converter
my_date_string = date_converter.timestamp_to_string(1284101485, "%B %d, %Y")

We can do this using data() method. C++11 provides this method.

Code Snippet

#include<bits/stdc++.h>
using namespace std;


int main()
{
  ios::sync_with_stdio(false);

  vector<int>v = {7, 8, 9, 10, 11};
  int *arr = v.data();

  for(int i=0; i<v.size(); i++)
  {
    cout<<arr[i]<<" ";
  }

  return 0;
}

If this is something you need to do a lot in your application, or you need to chain different calls, you can create an extension method:

public static String TrimEnd(this String str, int count)
{
    return str.Substring(0, str.Length - count);
}

and call it:

string oldString = "...Hello!";
string newString = oldString.Trim(1); //returns "...Hello"

or chained:

string newString = oldString.Substring(3).Trim(1);  //returns "Hello"

A couple of things might affect the results you're seeing:

1. You're treating clock_t as a floating-point type, I don't think it is.
2. You might be expecting (1^4) to do something else than compute the bitwise XOR of 1 and 4., i.e. it's 5.
3. Since the XOR is of constants, it's probably folded by the compiler, meaning it doesn't add a lot of work at runtime.
4. Since the output is buffered (it's just formatting the string and writing it to memory), it completes very quickly indeed.

You're not specifying how fast your machine is, but it's not unreasonable for this to run very quickly on modern hardware, no.

If you have it, try adding a call to sleep() between the start/stop snapshots. Note that sleep() is POSIX though, not standard C.

Try this. (Here we use text=Lines to keep the example self contained but in reality we would replace it with the file name.)

Lines <- "2009-01  12
2009-02  310
2009-03  2379
2009-04  234
2009-05  14
2009-08  1
2009-09  34
2009-10  2386"

library(zoo)
z <- read.zoo(text = Lines, FUN = as.yearmon)
plot(z)

The X axis is not so pretty with this data but if you have more data in reality it might be ok or you can use the code for a fancy X axis shown in the examples section of ?plot.zoo .

The zoo series, z, that is created above has a "yearmon" time index and looks like this:

> z
Jan 2009 Feb 2009 Mar 2009 Apr 2009 May 2009 Aug 2009 Sep 2009 Oct 2009 
      12      310     2379      234       14        1       34     2386 

"yearmon" can be used alone as well:

> as.yearmon("2000-03")
[1] "Mar 2000"

Note:

1. "yearmon" class objects sort in calendar order.

2. This will plot the monthly points at equally spaced intervals which is likely what is wanted; however, if it were desired to plot the points at unequally spaced intervals spaced in proportion to the number of days in each month then convert the index of z to "Date" class: time(z) <- as.Date(time(z)) .

placeBets(betList, stakeAmt) is an instance method not a static method. You need to create an instance of CBetfairAPI first:

MyBetfair api = new MyBetfair();
ArrayList bets = api.placeBets(betList, stakeAmt);

Inline content leaves space at the bottom for characters that descend (j, y, q):

https://developer.mozilla.org/en-US/docs/Images,_Tables,_and_Mysterious_Gaps

There are a couple fixes:

Use display: block;

<img style="display:block;" width="100%" height="100%" src="http://dummyimage.com/68x68/000/fff" />

or use vertical-align: bottom;

<img style="vertical-align: bottom;" width="100%" height="100%" src="http://dummyimage.com/68x68/000/fff" />

MySQL makes a difference between "localhost" and "127.0.0.1".

It might be possible that 'root'@'localhost' is not allowed because there is an entry in the user table that will only allow root login from 127.0.0.1.

This could also explain why some application on your server can connect to the database and some not because there are different ways of connecting to the database. And you currently do not allow it through "localhost".

A parameter is the variable which is part of the method’s signature (method declaration). An argument is an expression used when calling the method.

Consider the following code:

void Foo(int i, float f)
{
    // Do things
}

void Bar()
{
    int anInt = 1;
    Foo(anInt, 2.0);
}

Here i and f are the parameters, and anInt and 2.0 are the arguments.

I have found another reason: different versions used for icons in toolbox and references in the project. After inserting the objects in some form, the error started.

I struggled to find the working solution with ApplicationContext and TYPE_SYSTEM_ALERT and found confusing solutions, In case you want the dialog should be opened from any activity even the dialog is a singleton you have to use getApplicationContext(), and if want the dialog should be TYPE_SYSTEM_ALERT you will need the following steps:

first get the instance of dialog with correct theme, also you need to manage the version compatibility as I did in my following snippet:

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext(), R.style.Theme_AppCompat_Light);

After setting the title, message and buttons you have to build the dialog as:

AlertDialog alert = builder.create();

Now the type plays the main roll here, since this is the reason of crash, I handled the compatibility as following:

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        alert.getWindow().setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY - 1);

    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        alert.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
    }

Note: if you are using a custom dialog with AppCompatDialog as below:

AppCompatDialog dialog = new AppCompatDialog(getApplicationContext(), R.style.Theme_AppCompat_Light);

you can directly define your type to the AppCompatDialog instance as following:

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY - 1);

    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
    }

Don't forget to add the manifest permission:

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

Here's a fairly self-contained example. It turns a button red after 5sec.

    public void SetAlarm()
    {
        final Button button = buttons[2]; // replace with a button from your own UI
        BroadcastReceiver receiver = new BroadcastReceiver() {
            @Override public void onReceive( Context context, Intent _ )
            {
                button.setBackgroundColor( Color.RED );
                context.unregisterReceiver( this ); // this == BroadcastReceiver, not Activity
            }
        };

        this.registerReceiver( receiver, new IntentFilter("com.blah.blah.somemessage") );

        PendingIntent pintent = PendingIntent.getBroadcast( this, 0, new Intent("com.blah.blah.somemessage"), 0 );
        AlarmManager manager = (AlarmManager)(this.getSystemService( Context.ALARM_SERVICE ));

        // set alarm to fire 5 sec (1000*5) from now (SystemClock.elapsedRealtime())
        manager.set( AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + 1000*5, pintent );
    }

Remember though that the AlarmManager fires even when your application is not running. If you call this function and hit the Home button, wait 5 sec, then go back into your app, the button will have turned red.

I don't know what kind of behavior you would get if your app isn't in memory at all, so be careful with what kind of state you try to preserve.

For a somewhat narrow use case, docker issue 8838 mentions this sort-of-hack:

You just stop docker daemon and change container config in /var/lib/docker/containers/[container-id]/config.json (sic)

This solution updates the environment variables without the need to delete and re-run the container, having to migrate volumes and remembering parameters to run.

However, this requires a restart of the docker daemon. And, until issue issue 2658 is addressed, this includes a restart of all containers.

sift is a powerful collection filter for operations like this and much more advanced ones. It works client side in the browser or server side in node.js.

var collection = [
    {"id":"88","name":"Lets go testing"},
    {"id":"99","name":"Have fun boys and girls"},
    {"id":"108","name":"You are awesome!"}
];
var sifted = sift({id: {$not: 88}}, collection);

It supports filters like $in, $nin, $exists, $gte, $gt, $lte, $lt, $eq, $ne, $mod, $all, $and, $or, $nor, $not, $size, $type, and $regex, and strives to be API-compatible with MongoDB collection filtering.

Worked great on CentOS 6.5

Probably you are requesting for an external resource, this case IE needs the XDomain object. See the sample code below for how to make ajax request for all browsers with cross domains:

Tork.post = function (url,data,callBack,callBackParameter){
    if (url.indexOf("?")>0){
        data = url.substring(url.indexOf("?")+1)+"&"+ data;
        url = url.substring(0,url.indexOf("?"));
    }
    data += "&randomNumberG=" + Math.random() + (Tork.debug?"&debug=1":"");
    var xmlhttp;
    if (window.XDomainRequest)
    {
        xmlhttp=new XDomainRequest();
        xmlhttp.onload = function(){callBack(xmlhttp.responseText)};
    }
    else if (window.XMLHttpRequest)
        xmlhttp=new XMLHttpRequest();
    else
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    xmlhttp.onreadystatechange=function()
    {
        if (xmlhttp.readyState==4 && xmlhttp.status==200){
            Tork.msg("Response:"+xmlhttp.responseText);
            callBack(xmlhttp.responseText,callBackParameter);
            Tork.showLoadingScreen(false);
        }
    }
    xmlhttp.open("POST",Tork.baseURL+url,true);
    xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
    xmlhttp.send(data);
}

I like a more general functional approach:

/**
* converts a trig function taking radians to degrees
* @param {function} trigFunc - eg. Math.cos, Math.sin, etc.
* @param {number} angle - in degrees
* @returns {number}
*/
const dTrig = (trigFunc, angle) => trigFunc(angle * Math.PI / 180);

or,

function dTrig(trigFunc, angle) {
  return trigFunc(angle * Math.PI / 180);
}

which can be used with any radian-taking function:

dTrig(Math.sin, 90);
  // -> 1

dTrig(Math.tan, 180);
  // -> 0

Hope this helps!

I use it everywhere. On the topic of the effort for marking methods, I let Eclipse do it for me so, it's no additional effort.

JUnit 4 does not have any out-of-the-box mechanism for a test case to get it’s own name (including during setup and teardown).

I am not getting your question properly but as per your heading, you can convert any type of object to string by using toString() function on a String Object.

If you set numberOfLines to 0 (and the label to word wrap), the label will automatically wrap and use as many of lines as needed.

If you're editing a UILabel in IB, you can enter multiple lines of text by pressing option+return to get a line break - return alone will finish editing.

If you need to perform this List.contains(Object with field value equal to x) repeatedly, a simple and efficient workaround would be:

List<field obj type> fieldOfInterestValues = new ArrayList<field obj type>;
for(Object obj : List) {
    fieldOfInterestValues.add(obj.getFieldOfInterest());
}

Then the List.contains(Object with field value equal to x) would be have the same result as fieldOfInterestValues.contains(x);

select DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-0, -1) LastDate

In my mac machine, I checked whether I installed two java versions or not. I got this error. Because i installed two java at a time.

User -> Library -> Java -> JavaVirtualMachines -> version 1.8.0 and version 11.0.1 has been installed.

I removed version 11.0.1. Now its working fine.

from the book named Decompiling Android by Godfrey Nolan

Security dictates that pointers aren’t used in Java so hackers can’t break out of an application and into the operating system. No pointers means that something else----in this case, the JVM----has to take care of the allocating and freeing memory. Memory leaks should also become a thing of the past, or so the theory goes. Some applications written in C and C++ are notorious for leaking memory like a sieve because programmers don’t pay attention to freeing up unwanted memory at the appropriate time----not that anybody reading this would be guilty of such a sin. Garbage collection should also make programmers more productive, with less time spent on debugging memory problems.

I am promoting my comment to an answer:

The easy way is:

You could draw in the original 'frame' itself instead of using gray image.

The hard way (method you were trying to implement):

backtorgb = cv2.cvtColor(gray,cv2.COLOR_GRAY2RGB) is the correct syntax.

If you want to search recursively, you can use this beautiful piece of code:

public static FileInfo GetNewestFile(DirectoryInfo directory) {
   return directory.GetFiles()
       .Union(directory.GetDirectories().Select(d => GetNewestFile(d)))
       .OrderByDescending(f => (f == null ? DateTime.MinValue : f.LastWriteTime))
       .FirstOrDefault();                        
}

Just call it the following way:

FileInfo newestFile = GetNewestFile(new DirectoryInfo(@"C:\directory\"));

and that's it. Returns a FileInfo instance or null if the directory is empty.

As all the other correct answers says, die and exit are identical/aliases.

Although I have a personal convention that when I want to end the execution of a script when it is expected and desired, I use exit;. And when I need to end the execution due to some problems (couldn't connect to db, can't write to file etc.), I use die("Something went wrong."); to "kill" the script.

When I use exit:

header( "Location: http://www.example.com/" ); /* Redirect browser */
/* Make sure that code below does not get executed when we redirect. */
exit; // I would like to end now.

When I use die:

$data = file_get_contents( "file.txt" );
if( $data === false ) {
    die( "Failure." ); // I don't want to end, but I can't continue. Die, script! Die!
}
do_something_important( $data );

This way, when I see exit at some point in my code, I know that at this point I want to exit because the logic ends here. When I see die, I know that I'd like to continue execution, but I can't or shouldn't due to error in previous execution.

Of course this only works when working on a project alone. When there is more people nobody will prevent them to use die or exit where it does not fit my conventions...

Based on what i've searched, i think this is the best answers that i've found out Android 6.0 multiple permissions

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

Another great implementation is balupton's jQuery History which will use the native onhashchange event if it is supported by the browser, if not it will use an iframe or interval appropriately for the browser to ensure all the expected functionality is successfully emulated. It also provides a nice interface to bind to certain states.

Another project worth noting as well is jQuery Ajaxy which is pretty much an extension for jQuery History to add ajax to the mix. As when you start using ajax with hashes it get's quite complicated!

For me work like this: 1. Stop mysql: systemctl stop mysqld

2. Set the mySQL environment option systemctl set-environment MYSQLD_OPTS="--skip-grant-tables"

3. Start mysql usig the options you just set systemctl start mysqld

4. Login as root mysql -u root

5. After login I use FLUSH PRIVILEGES; tell the server to reload the grant tables so that account-management statements work. If i don't do that i receive this error trying to update the password: "Can't find any matching row in the user table"

Now docker-compose supports variable substitution.

Compose uses the variable values from the shell environment in which docker-compose is run. For example, suppose the shell contains POSTGRES_VERSION=9.3 and you supply this configuration in your docker-compose.yml file:

db:
  image: "postgres:${POSTGRES_VERSION}"

When you run docker-compose up with this configuration, Compose looks for the POSTGRES_VERSION environment variable in the shell and substitutes its value in. For this example, Compose resolves the image to postgres:9.3 before running the configuration.

So because pod update SomePod touches everything in the latest versions of cocoapods, I found a workaround.

Follow the next steps:

1. Remove SomePod from the Podfile

2. Run pod install

pods will now remove SomePod from our project and from the Podfile.lock file.

3. Put back SomePod into the Podfile

4. Run pod install again

This time the latest version of our pod will be installed and saved in the Podfile.lock.

Use the find and replace command accessible through ctrl+h, make sure you are searching through the functions of the cells. You can then wildcards to accommodate any deviations of the formula. * for # wildcards, ? for charcter wildcards, and ~? or ~* to search for ? or *.

If you're more comfortable PCRE regex syntax, which

1. supports the non-greedy operator ?, as you asked in OP; and
2. doesn't require backwhacking grouping and cardinality operators (an utterly counterintuitive vim syntax requirement since you're not matching literal characters but specifying operators); and

3. you have [g]vim compiled with perl feature, test using

   :ver and inspect features; if +perl is there you're good to go)

try search/replace using

:perldo s///

Example. Swap src and alt attributes in img tag:

<p class="logo"><a href="/"><img src="/caminoglobal_en/includes/themes/camino/images/header_logo.png" alt=""></a></p>

:perldo s/(src=".*?")\s+(alt=".*?")/$2 $1/

<p class="logo"><a href="/"><img alt="" src="/caminoglobal_en/includes/themes/camino/images/header_logo.png"></a></p>

I know this is a really old topic now, but as it's the first one that came up on my google search I just wanted to add my solution to it:

I had this problem as well with an icon that was supplied by a client. It displayed in all browsers apart from IE. Adding the link or meta tags didn't work, so I started to look at the format of the icon file.
It appeared to be a valid icon file (not just a renamed image), but what fixed it in the end was to convert it to an image, save it as a GIF, and then converting it back to an icon.
Also make sure to clear the IE cache while you're testing.

You may be an administrator on the workstation, but that means nothing to SQL Server. Your login has to be a member of the sysadmin role in order to perform the actions in question. By default, the local administrators group is no longer added to the sysadmin role in SQL 2008 R2. You'll need to login with something else (sa for example) in order to grant yourself the permissions.

Since Joda is getting faded, someone might want to convert LocaltDate to LocalDateTime in Java 8. In Java 8 LocalDateTime it will give a way to create a LocalDateTime instance using a LocalDate and LocalTime. Check here.

public static LocalDateTime of(LocalDate date, LocalTime time)

Sample would be,

    // just to create a sample LocalDate
    DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyyMMdd");
    LocalDate ld = LocalDate.parse("20180306", dtf);

    // convert ld into a LocalDateTime
    // We need to specify the LocalTime component here as well, it can be any accepted value
    LocalDateTime ldt = LocalDateTime.of(ld, LocalTime.of(0,0)); // 2018-03-06T00:00

Just for reference, For getting the epoch seconds below can be used,

    ZoneId zoneId = ZoneId.systemDefault();
    long epoch = ldt.atZone(zoneId).toEpochSecond(); 

    // If you only care about UTC
    long epochUTC = ldt.toEpochSecond(ZoneOffset.UTC);

The whole git resetting business looked far to complicating for me.

So I did something along the lines to get my src folder in the state i had a few commits ago

# reset the local state
git reset <somecommit> --hard 
# copy the relevant part e.g. src (exclude is only needed if you specify .)
tar cvfz /tmp/current.tgz --exclude .git  src
# get the current state of git
git pull
# remove what you don't like anymore
rm -rf src
# restore from the tar file
tar xvfz /tmp/current.tgz
# commit everything back to git
git commit -a
# now you can properly push
git push

This way the state of affairs in the src is kept in a tar file and git is forced to accept this state without too much fiddling basically the src directory is replaced with the state it had several commits ago.

I solved the problem the following way, and it works well without any error. Consider two files a.py and b.py.

I added this to a.py and it worked.

if __name__ == "__main__":
        main ()

a.py:

import b
y = 2
def main():
    print ("a out")
    print (b.x)

if __name__ == "__main__":
    main ()

b.py:

import a
print ("b out")
x = 3 + a.y

The output I get is

>>> b out 
>>> a out 
>>> 5

Sphinx is mainly a tool for formatting docs written independently from the source code, as I understand it.

For generating API docs from Python docstrings, the leading tools are pdoc and pydoctor. Here's pydoctor's generated API docs for Twisted and Bazaar.

Of course, if you just want to have a look at the docstrings while you're working on stuff, there's the "pydoc" command line tool and as well as the help() function available in the interactive interpreter.

I was/am in the same boat as you for different reasons (partly educational, partly constraints). I had to re-write all the containers of the standard library and the containers had to conform to the standard. That means, if I swap out my container with the stl version, the code would work the same. Which also meant that I had to re-write the iterators.

Anyway, I looked at EASTL. Apart from learning a ton about containers that I never learned all this time using the stl containers or through my undergraduate courses. The main reason is that EASTL is more readable than the stl counterpart (I found this is simply because of the lack of all the macros and straight forward coding style). There are some icky things in there (like #ifdefs for exceptions) but nothing to overwhelm you.

As others mentioned, look at cplusplus.com's reference on iterators and containers.

Fresh answer 2018:

Step 1 Launch Microsoft Paint. Not Paint.Net but plain Paint

Step 2 Open the image you want to convert to icon format by clicking the “Paint” toolbar tab and selecting “Open.”

Step 3 Click the “Paint” tab, highlight the “Save As” option and select the “BMP picture” option. As 256-colored. There is a dropdown list.

Step 4 You have to open it in Paint.net now. Enter a file name for the icon and type “.ico” (without quotations) as the file extension. Select your preferred output folder for the icon and click “Save.”(still in bmp type) , exposing auto definition in saving parameters window.

This is a solution for those WHO DOESN'T WANT THE THIRD PARTY APPS TO GAIN PERMISSIONS ON THEIR COMP.
I use this simple way to create custom icons for folders on my desktop or documents.

I'll Explain how to add an image using Android studio(2.3.3). First you need to add the image into res/drawable folder in the project. Like below

Now in go to activity_main.xml (or any activity you need to add image) and select the Design view. There you can see your Palette tool box on left side. You need to drag and drop ImageView.

It will prompt you Resources dialog box. In there select Drawable under the project section you can see your image. Like below

Select the image you want press Ok you can see the image on the Design view. If you want it configure using xml it would look like below.

<ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:srcCompat="@drawable/homepage"
        tools:layout_editor_absoluteX="55dp"
        tools:layout_editor_absoluteY="130dp" />

You need to give image location using

app:srcCompat="@drawable/imagename"

try with following code. make elements with class name page-scroll and keep id name to href of corresponding links

$('a.page-scroll').bind('click', function(event) {
        var $anchor = $(this);
        $('html, body').stop().animate({
            scrollTop: ($($anchor.attr('href')).offset().top - 50)
        }, 1250, 'easeInOutExpo');
        event.preventDefault();
    });

Motivation: You want to print prettify JSON response after curl command request.

Solution: json_pp - commandline tool that converts between some input and output formats (one of them is JSON). This program was copied from json_xs and modified. The default input format is json and the default output format is json with pretty option.

Synposis: json_pp [-v] [-f from_format] [-t to_format] [-json_opt options_to_json1[,options_to_json2[,...]]]

Formula: <someCommand> | json_pp

Example:

Request

curl -X https://jsonplaceholder.typicode.com/todos/1 | json_pp 

Response

{
   "completed" : false,
   "id" : 1,
   "title" : "delectus aut autem",
   "userId" : 1
}

How to configure and troubleshoot <p:fileUpload> depends on PrimeFaces and JSF version.

All PrimeFaces versions

The below requirements apply to all PrimeFaces versions:

1. The enctype attribute of the <h:form> needs to be set to multipart/form-data. When this is absent, the ajax upload may just work, but the general browser behavior is unspecified and dependent on form composition and webbrowser make/version. Just always specify it to be on the safe side.

2. When using mode="advanced" (i.e. ajax upload, this is the default), then make sure that you've a <h:head> in the (master) template. This will ensure that the necessary JavaScript files are properly included. This is not required for mode="simple" (non-ajax upload), but this would break look'n'feel and functionality of all other PrimeFaces components, so you don't want to miss that anyway.

3. When using mode="simple" (i.e. non-ajax upload), then ajax must be disabled on any PrimeFaces command buttons/links by ajax="false", and you must use <p:fileUpload value> with <p:commandButton action> instead of <p:fileUpload listener>.

So, if you want (auto) file upload with ajax support (mind the <h:head>!):

<h:form enctype="multipart/form-data">
    <p:fileUpload listener="#{bean.upload}" auto="true" /> // For PrimeFaces version older than 8.x this should be fileUploadListener instead of listener.
</h:form>

public void upload(FileUploadEvent event) {
    UploadedFile uploadedFile = event.getFile();
    String fileName = uploadedFile.getFileName();
    String contentType = uploadedFile.getContentType();
    byte[] contents = uploadedFile.getContents(); // Or getInputStream()
    // ... Save it, now!
}

Or if you want non-ajax file upload:

<h:form enctype="multipart/form-data">
    <p:fileUpload mode="simple" value="#{bean.uploadedFile}" />
    <p:commandButton value="Upload" action="#{bean.upload}" ajax="false" />
</h:form>

private transient UploadedFile uploadedFile; // +getter+setter

public void upload() {
    String fileName = uploadedFile.getFileName();
    String contentType = uploadedFile.getContentType();
    byte[] contents = uploadedFile.getContents(); // Or getInputStream()
    // ... Save it, now!
}

Do note that ajax-related attributes such as auto, allowTypes, update, onstart, oncomplete, etc are ignored in mode="simple". So it's needless to specify them in such case.

Also note that you should read the file contents immediately inside the abovementioned methods and not in a different bean method invoked by a later HTTP request. This is because the uploaded file contents is request scoped and thus unavailable in a later/different HTTP request. Any attempt to read it in a later request will most likely end up with java.io.FileNotFoundException on the temporary file.

PrimeFaces 8.x

Configuration is identical to the 5.x version info below, but if your listener is not called, check if the method attribute is called listener and not (like with pre 8.x versions) fileUploadListener.

PrimeFaces 5.x

This does not require any additional configuration if you're using JSF 2.2 and your faces-config.xml is also declared conform JSF 2.2 version. You do not need the PrimeFaces file upload filter at all and you also do not need the primefaces.UPLOADER context parameter in web.xml. In case it's unclear to you how to properly install and configure JSF depending on the target server used, head to How to properly install and configure JSF libraries via Maven? and "Installing JSF" section of our JSF wiki page.

If you're however not using JSF 2.2 yet and you can't upgrade it (should be effortless when already on a Servlet 3.0 compatible container), then you need to manually register the below PrimeFaces file upload filter in web.xml (it will parse the multi part request and fill the regular request parameter map so that FacesServlet can continue working as usual):

<filter>
    <filter-name>primeFacesFileUploadFilter</filter-name>
    <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>primeFacesFileUploadFilter</filter-name>
    <servlet-name>facesServlet</servlet-name>
</filter-mapping>

The <servlet-name> value of facesServlet must match exactly the value in the <servlet> entry of the javax.faces.webapp.FacesServlet in the same web.xml. So if it's e.g. Faces Servlet, then you need to edit it accordingly to match.

PrimeFaces 4.x

The same story as PrimeFaces 5.x applies on 4.x as well.

There's only a potential problem in getting the uploaded file content by UploadedFile#getContents(). This will return null when native API is used instead of Apache Commons FileUpload. You need to use UploadedFile#getInputStream() instead. See also How to insert uploaded image from p:fileUpload as BLOB in MySQL?

Another potential problem with native API will manifest is when the upload component is present in a form on which a different "regular" ajax request is fired which does not process the upload component. See also File upload doesn't work with AJAX in PrimeFaces 4.0/JSF 2.2.x - javax.servlet.ServletException: The request content-type is not a multipart/form-data.

Both problems can also be solved by switching to Apache Commons FileUpload. See PrimeFaces 3.x section for detail.

PrimeFaces 3.x

This version does not support JSF 2.2 / Servlet 3.0 native file upload. You need to manually install Apache Commons FileUpload and explicitly register the file upload filter in web.xml.

You need the following libraries:

• commons-fileupload.jar
• commons-io.jar

Those must be present in the webapp's runtime classpath. When using Maven, make sure they are at least runtime scoped (default scope of compile is also good). When manually carrying around JARs, make sure they end up in /WEB-INF/lib folder.

The file upload filter registration detail can be found in PrimeFaces 5.x section here above. In case you're using PrimeFaces 4+ and you'd like to explicitly use Apache Commons FileUpload instead of JSF 2.2 / Servlet 3.0 native file upload, then you need next to the mentioned libraries and filter also the below context param in web.xml:

<context-param>
    <param-name>primefaces.UPLOADER</param-name>
    <param-value>commons</param-value><!-- Allowed values: auto, native and commons. -->
</context-param>

Troubleshooting

In case it still doesn't work, here are another possible causes unrelated to PrimeFaces configuration:

1. Only if you're using the PrimeFaces file upload filter: There's another Filter in your webapp which runs before the PrimeFaces file upload filter and has already consumed the request body by e.g. calling getParameter(), getParameterMap(), getReader(), etcetera. A request body can be parsed only once. When you call one of those methods before the file upload filter does its job, then the file upload filter will get an empty request body.

   To fix this, you'd need to put the <filter-mapping> of the file upload filter before the other filter in web.xml. If the request is not a multipart/form-data request, then the file upload filter will just continue as if nothing happened. If you use filters that are automagically added because they use annotations (e.g. PrettyFaces), you might need to add explicit ordering via web.xml. See How to define servlet filter order of execution using annotations in WAR

2. Only if you're using the PrimeFaces file upload filter: There's another Filter in your webapp which runs before the PrimeFaces file upload filter and has performed a RequestDispatcher#forward() call. Usually, URL rewrite filters such as PrettyFaces do this. This triggers the FORWARD dispatcher, but filters listen by default on REQUEST dispatcher only.

   To fix this, you'd need to either put the PrimeFaces file upload filter before the forwarding filter, or to reconfigure the PrimeFaces file upload filter to listen on FORWARD dispatcher too:

    <filter-mapping>
        <filter-name>primeFacesFileUploadFilter</filter-name>
        <servlet-name>facesServlet</servlet-name>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>
   

3. There's a nested <h:form>. This is illegal in HTML and the browser behavior is unspecified. More than often, the browser won't send the expected data on submit. Make sure that you are not nesting <h:form>. This is completely regardless of the form's enctype. Just do not nest forms at all.

If you're still having problems, well, debug the HTTP traffic. Open the webbrowser's developer toolset (press F12 in Chrome/Firebug23+/IE9+) and check the Net/Network section. If the HTTP part looks fine, then debug the JSF code. Put a breakpoint on FileUploadRenderer#decode() and advance from there.

Saving uploaded file

After you finally got it to work, your next question shall probably be like "How/where do I save the uploaded file?". Well, continue here: How to save uploaded file in JSF.

Try something like this

select Cast((SPGI09_EARLY_OVER_T – (SPGI09_OVER_WK_EARLY_ADJUST_T) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T  + SPGR99_ON_TIME_Q)) as varchar(20) + '%' as percentageAmount
from CSPGI09_OVERSHIPMENT

I presume the value is a representation in percentage - if not convert it to a valid percentage total, then add the % sign and convert the column to varchar.

It seems that there is a typo, since 1104*1104*50=60940800 and you are trying to reshape to dimensions 50,1104,104. So it seems that you need to change 104 to 1104.

If you are testing for file existence you want -e not -L. -L tests for a symlink.

Just check your php.ini file, In this file Semicolon(;) used for comment if you see then remove semicolon ;.

;extension=mysql.dll

Now your extension is enable but you need to restart appache

extension=mysql.dll

Read directly into allocated space with fgets().

Special care is need to distinguish a successful read, end-of-file, input error and out-of memory. Proper memory management needed on EOF.

This method retains a line's '\n'.

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

#define FGETS_ALLOC_N 128

char* fgets_alloc(FILE *istream) {
  char* buf = NULL;
  size_t size = 0;
  size_t used = 0;
  do {
    size += FGETS_ALLOC_N;
    char *buf_new = realloc(buf, size);
    if (buf_new == NULL) {
      // Out-of-memory
      free(buf);
      return NULL;
    }
    buf = buf_new;
    if (fgets(&buf[used], (int) (size - used), istream) == NULL) {
      // feof or ferror
      if (used == 0 || ferror(istream)) {
        free(buf);
        buf = NULL;
      }
      return buf;
    }
    size_t length = strlen(&buf[used]);
    if (length + 1 != size - used) break;
    used += length;
  } while (buf[used - 1] != '\n');
  return buf;
}

Sample usage

int main(void) {
  FILE *istream = stdin;
  char *s;
  while ((s = fgets_alloc(istream)) != NULL) {
    printf("'%s'", s);
    free(s);
    fflush(stdout);
  }
  if (ferror(istream)) {
    puts("Input error");
  } else if (feof(istream)) {
    puts("End of file");
  } else {
    puts("Out of memory");
  }
  return 0;
}

I need this so often that I created a function in my ~/.bashrc file:

chmodf() {
        find $2 -type f -exec chmod $1 {} \;
}
chmodd() {
        find $2 -type d -exec chmod $1 {} \;
}

Now I can use these shortcuts:

chmodd 0775 .
chmodf 0664 .

et.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {

            et.setHint(temp +" Characters");
        }
    });

Above answers are correct and they give great and short answer.

I got to this thread while looking for the current directory of an executing process. In .net 1.1 Microsoft introduced:

Directory.GetCurrentDirectory();

Seems to work well (but doesn't return the name of the process itself).

Delete this is legal as long as object is in heap. You would need to require object to be heap only. The only way to do that is to make the destructor protected - this way delete may be called ONLY from class , so you would need a method that would ensure deletion

As oliver writes:

add_header works as well with proxy_pass as without.

However, as Shane writes, as of Nginx 1.7.5, you must pass always in order to get add_header to work for error responses, like so:

add_header  X-Upstream  $upstream_addr always;

I know this is kind of late but this plugin should work. http://remysharp.com/2009/01/26/element-in-view-event-plugin/

$('p.inview').bind('inview', function (event, visible) {
if (visible) {
  $(this).text('You can see me!');
} else {
  $(this).text('Hidden again');
}

import datetime
mydate = datetime.datetime.now()
mydate.strftime("%B")

Returns: December

Some more info on the Python doc website

[EDIT : great comment from @GiriB] You can also use %b which returns the short notation for month name.

mydate.strftime("%b")

For the example above, it would return Dec.

As others have said, @Transient is used to mark fields which shouldn't be persisted. Consider this short example:

public enum Gender { MALE, FEMALE, UNKNOWN }

@Entity
public Person {
    private Gender g;
    private long id;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    public long getId() { return id; }
    public void setId(long id) { this.id = id; }

    public Gender getGender() { return g; }    
    public void setGender(Gender g) { this.g = g; }

    @Transient
    public boolean isMale() {
        return Gender.MALE.equals(g);
    }

    @Transient
    public boolean isFemale() {
        return Gender.FEMALE.equals(g);
    }
}

When this class is fed to the JPA, it persists the gender and id but doesn't try to persist the helper boolean methods - without @Transient the underlying system would complain that the Entity class Person is missing setMale() and setFemale() methods and thus wouldn't persist Person at all.

Looks like this will be finally supported in the SQL Server 2019! SQL Server 2019 - whats new?

From BOL:

UTF-8 support

Full support for the widely used UTF-8 character encoding as an import or export encoding, or as database-level or column-level collation for text data. UTF-8 is allowed in the CHAR and VARCHAR datatypes, and is enabled when creating or changing an object’s collation to a collation with the UTF8 suffix.

For example,LATIN1_GENERAL_100_CI_AS_SC to LATIN1_GENERAL_100_CI_AS_SC_UTF8. UTF-8 is only available to Windows collations that support supplementary characters, as introduced in SQL Server 2012. NCHAR and NVARCHAR allow UTF-16 encoding only, and remain unchanged.

This feature may provide significant storage savings, depending on the character set in use. For example, changing an existing column data type with ASCII strings from NCHAR(10) to CHAR(10) using an UTF-8 enabled collation, translates into nearly 50% reduction in storage requirements. This reduction is because NCHAR(10) requires 22 bytes for storage, whereas CHAR(10) requires 12 bytes for the same Unicode string.

2019-05-14 update:

Documentation seems to be updated now and explains our options staring in MSSQL 2019 in section "Collation and Unicode Support".

2019-07-24 update:

Article by Pedro Lopes - Senior Program Manager @ Microsoft about introducing UTF-8 support for Azure SQL Database

My case was that i was using RDS (mysql db verion 8) of AWS and was connecting my application through EC2 (my php code 5.6 was in EC2).

Here in this case since it is RDS there is no my.cnf the parameters are maintained by PARAMETER Group of AWS. Refer: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_WorkingWithParamGroups.html

so what i did was:

1. Created a new Parameter group and then edited them.

2. Searched all character-set parameters. These are blank by default. edit them individually and select utf8 from drop down list.

character_set_client, character_set_connection, character_set_database, character_set_server

3. SAVE

And then most important, Rebooted RDS instance.

This has solved my problem and connection from php5.6 to mysql 8.x was working great.

hope this helps.

Please view this image for better understanding. enter image description here

My only doubt would be how applicable this technique would be on multi-byte strings, but if that's not a consideration, then I suspect you're covered. (If in doubt, mb_substr() seems an obviously safe choice.)

However, from a big picture perspective, I have to wonder how often you need to access the 'n'th character in a string for this to be a key consideration.

I know this is not an ideal question to answer but as the OP seems to be a beginner, I'd love to share some basic knowledge with him... Hope everybody understands

OP, you can convert a string to type Boolean by using any of the methods stated below:

 string sample = "True";
 bool myBool = bool.Parse(sample);

 ///or

 bool myBool = Convert.ToBoolean(sample);

bool.Parse expects one parameter which in this case is sample, .ToBoolean also expects one parameter.

You can use TryParse which is the same as Parse but it doesn't throw any exception :)

  string sample = "false";
  Boolean myBool;

  if (Boolean.TryParse(sample , out myBool))
  {
  }

Please note that you cannot convert any type of string to type Boolean because the value of a Boolean can only be True or False

Hope you understand :)

What helped me on Windows 10 was just ticking off "Read Only" of project node_modules.

The format for HTTP headers is defined in the HTTP specification. I'm going to talk about HTTP 1.1, for which the specification is RFC 2616. In section 4.2, 'Message Headers', the general structure of a header is defined:

   message-header = field-name ":" [ field-value ]
   field-name     = token
   field-value    = *( field-content | LWS )
   field-content  = <the OCTETs making up the field-value
                    and consisting of either *TEXT or combinations
                    of token, separators, and quoted-string>

This definition rests on two main pillars, token and TEXT. Both are defined in section 2.2, 'Basic Rules'. Token is:

   token          = 1*<any CHAR except CTLs or separators>

In turn resting on CHAR, CTL and separators:

   CHAR           = <any US-ASCII character (octets 0 - 127)>

   CTL            = <any US-ASCII control character
                    (octets 0 - 31) and DEL (127)>

   separators     = "(" | ")" | "<" | ">" | "@"
                  | "," | ";" | ":" | "\" | <">
                  | "/" | "[" | "]" | "?" | "="
                  | "{" | "}" | SP | HT

TEXT is:

   TEXT           = <any OCTET except CTLs,
                    but including LWS>

Where LWS is linear white space, whose definition i won't reproduce, and OCTET is:

   OCTET          = <any 8-bit sequence of data>

There is a note accompanying the definition:

The TEXT rule is only used for descriptive field contents and values
that are not intended to be interpreted by the message parser. Words
of *TEXT MAY contain characters from character sets other than ISO-
8859-1 [22] only when encoded according to the rules of RFC 2047
[14].

So, two conclusions. Firstly, it's clear that the header name must be composed from a subset of ASCII characters - alphanumerics, some punctuation, not a lot else. Secondly, there is nothing in the definition of a header value that restricts it to ASCII or excludes 8-bit characters: it's explicitly composed of octets, with only control characters barred (note that CR and LF are considered controls). Furthermore, the comment on the TEXT production implies that the octets are to be interpreted as being in ISO-8859-1, and that there is an encoding mechanism (which is horrible, incidentally) for representing characters outside that encoding.

So, to respond to @BalusC in particular, it's quite clear that according to the specification, header values are in ISO-8859-1. I've sent high-8859-1 characters (specifically, some accented vowels as used in French) in a header out of Tomcat, and had them interpreted correctly by Firefox, so to some extent, this works in practice as well as in theory (although this was a Location header, which contains a URL, and these characters are not legal in URLs, so this was actually illegal, but under a different rule!).

That said, i wouldn't rely on ISO-8859-1 working across all servers, proxies, and clients, so i would stick to ASCII as a matter of defensive programming.

As described in Documentation Environment.getExternalStorageDirectory() :

Environment.getExternalStorageDirectory() Return the primary shared/external storage directory.

This is an example of how to use it reading an image :

String fileName = "stored_image.jpg";
 String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
 String pathDir = baseDir + "/Android/data/com.mypackage.myapplication/";

 File f = new File(pathDir + File.separator + fileName);

        if(f.exists()){
          Log.d("Application", "The file " + file.getName() + " exists!";
         }else{
          Log.d("Application", "The file no longer exists!";
         }

pip has a --no-dependencies switch. You should use that.

For more information, run pip install -h, where you'll see this line:

--no-deps, --no-dependencies
                        Ignore package dependencies

NSString *path = [[NSBundle mainBundle] pathForResource:@"document" ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];

The picture you showd in the question is actually a chart made using JavaScript. It is actually very easy to plot multi-axis chart using JavaScript with the help of 3rd party libraries like HighChart.js or D3.js. Here I propose to use the Funfun Excel add-in which allows you to use JavaScript directly in Excel so you could plot chart like you've showed easily in Excel. Here I made an example using Funfun in Excel.

You could see in this chart you have one axis of Rainfall at the left side while two axis of Temperature and Sea-pressure level at the right side. This is also a combination of line chart and bar chart for different datasets. In this example, with the help of the Funfun add-in, I used HighChart.js to plot this chart.

Funfun also has an online editor in which you could test your JavaScript code with you data. You could check the detailed code of this example on the link below.

https://www.funfun.io/1/#/edit/5a43b416b848f771fbcdee2c

Edit: The content on the previous link has been changed so I posted a new link here. The link below is the original link https://www.funfun.io/1/#/edit/5a55dc978dfd67466879eb24

If you are satisfied with the result you achieved in the online editor, you could easily load the result into you Excel using the URL above. Of couse first you need to insert the Funfun add-in from Insert - My add-ins. Here are some screenshots showing how you could do this.

Disclosure: I'm a developer of Funfun

It depends.

The web server on the other end will be set to a certain port, usually 80 and will only accept requests on that specific port. Something along the chain will need to be talking to port 80 to the website.

If you control the website, then you can change the port, or get it to accept requests on multiple ports.

If the website is already talking on a different port, you can just use the colon syntax to reference another port (eg: http://server.com:1234 for port 1234).

If you want to use a different port on your client end, but you want to talk to port 80 at the web server end, you'll need to route traffic from port x to port 80. A common way to get this up and running is to use Port Fowarding. ssh can do this for you, see here for a Unix/technical overview or here if you're on Windows.

Hope that helps.

Are you looking to do something like this http://jsfiddle.net/robert/xhHkG/

$('#transactionType').attr({
    'multiple': true,
    'size' : 10
});

Put that in a $(function() {...}) or some other onload

Edit

Reread your question, you're not really looking for a multiple select... but a dropdown box that allows you to select multiple. Yeah, probably best to use a plugin for that or write it from the ground up, it's not a "quick answer" type deal though.

Something like this should work:

<%=Html.TextBox("test", new { style="width:50px" })%>

Or better:

<%=Html.TextBox("test")%>

<style type="text/css">
    input[type="text"] { width:50px; }     
</style>

My solution is based on XML configuration using spring-boot-starter-log4j. The example is a basic example using spring-boot-starter and the two Loggers writes into different log files.

Use generic types !

  class DataExtraction<T>
{
    DateRangeReport dateRange;
    List<Predicate> predicates;
    List<string> cids;

    public DataExtraction( DateRangeReport dateRange,
                           List<Predicate> predicates,
                           List<string> cids)            

    {
        this.dateRange = dateRange;
        this.predicates = predicates;
        this.cids = cids;
    }
}

And call it like this :

  DataExtraction<AdPerformanceRow> extractor = new DataExtraction<AdPerformanceRow>(dates, predicates , cids);

You can use the following function with gcc running under x86 processors:

unsigned long long rdtsc()
{
  #define rdtsc(low, high) \
         __asm__ __volatile__("rdtsc" : "=a" (low), "=d" (high))

  unsigned int low, high;
  rdtsc(low, high);
  return ((ulonglong)high << 32) | low;
}

with Digital Mars C++:

unsigned long long rdtsc()
{
   _asm
   {
        rdtsc
   }
}

which reads the high performance timer on the chip. I use this when doing profiling.

I've solved this problem by deleting the google-services.json file and downloading it again from Firebase console.

My problem, it showed an error called "The class Form1 can be designed, but is not the first class in the file. Visual Studio requires that designers use the first class in the file. Move the class code so that it is the first class in the file and try loading the designer again. ". So I moved the Form class to the first one and it worked. :)

I suggest you to see "How do I run a bat file in the background from another bat file?"

Also, good answer (of using start command) was given in "Parallel execution of shell processes" question page here;

But my recommendation is to use PowerShell. I believe it will perfectly suit your needs.

You should be able to use reduce.

var sum = array.reduce(function(pv, cv) { return pv + cv; }, 0);

Source

And with arrow functions introduced in ES6, it's even simpler:

sum = array.reduce((pv, cv) => pv + cv, 0);

I have a label on my form receiving the sum of numbers from Column D in Sheet1. I am only interested in rows 2 to 50, you can use a row counter if your row count is dynamic. I have some blank entries as well in column D and they are ignored.

Me.lblRangeTotal = Application.WorksheetFunction.Sum(ThisWorkbook.Sheets("Sheet1").Range("D2:D50"))

this work for me :D

    function setActive() {
      aObj = document.getElementById('menu').getElementsByTagName('a');
      for(i=0;i<aObj.length;i++) {
        if(document.location.href.indexOf(aObj[i].href)>=0) {
          var activeurl = window.location;
          $('a[href="'+activeurl+'"]').parent('li').addClass('active');
        }
      }
    }

    window.onload = setActive;

The C language doesn't prohibit that kind of #include, but the resulting translation unit still has to be valid C.

I don't know what program you're using with a .prj file. If you're using something like "make" or Visual Studio or whatever, just make sure that you set its list of files to be compiled without the one that can't compile independently.

A simple solution would be to just use webView.scrollView.contentSize but I don't know if this works with JavaScript. If there is no JavaScript used this works for sure:

- (void)webViewDidFinishLoad:(UIWebView *)aWebView {
    CGSize contentSize = aWebView.scrollView.contentSize;
    NSLog(@"webView contentSize: %@", NSStringFromCGSize(contentSize));
}

To access the elements in the array, use array notation: $product['prodname']

$product->prodname is object notation, which can only be used to access object attributes and methods.

Every method needs to accept one argument: The instance itself (or the class if it is a static method).

I did try using a Monitor (code below) which appears to work but has a GOTCHA... when you have multiple threads it will give... System.Threading.SynchronizationLockException Object synchronization method was called from an unsynchronized block of code.

using System;
using System.Threading;
using System.Threading.Tasks;

namespace MyNamespace

    public class ThreadsafeFooModifier : 
    {
        private readonly object _lockObject;

        public async Task<FooResponse> ModifyFooAsync()
        {
            FooResponse result;
            Monitor.Enter(_lockObject);
            try
            {
                result = await SomeFunctionToModifyFooAsync();
            }
            finally
            {
                Monitor.Exit(_lockObject);
            }
            return result;
        }
    }
}

Prior to this I was simply doing this, but it was in an ASP.NET controller so it resulted in a deadlock.

public async Task<FooResponse> ModifyFooAsync() { lock(lockObject) { return SomeFunctionToModifyFooAsync.Result; } }

The Media Source Extensions has been proposed which would allow for Adaptive Bitrate Streaming implementations.

var firstTime = DateTime.Now;
var secondTime = DateTime.Now.AddMilliseconds(600);
var diff = secondTime.Subtract(firstTime).Milliseconds;


// var diff = DateTime.Now.AddMilliseconds(600).Subtract(DateTime.Now).Milliseconds;

Why not just use the following simple call (with any exception handling added)?

You can also install gems in your local environment (without sudo) with

gem install --user-install <gemname>

I recommend that so you don't mess with your system-level configuration even if it's a single-user computer.

You can check where the gems go by looking at gempaths with gem environment. In my case it's "~/.gem/ruby/1.8".

If you need some binaries from local installs added to your path, you can add something to your bashrc like:

if which ruby >/dev/null && which gem >/dev/null; then
    PATH="$(ruby -r rubygems -e 'puts Gem.user_dir')/bin:$PATH"
fi

It seems incredible that I could add something to this after eight years, but for the case of Java I would like to point readers to the Random.nextGaussian() method, which generates a Gaussian distribution with mean 0.0 and standard deviation 1.0 for you.

A simple addition and/or multiplication will change the mean and standard deviation to your needs.

A bit late and not exactly suited here, but I'm gonna add my solution here, because my question had been closed as a duplicate of this one, and because this solution is completely different.

I needed a general way to instruct Json.NET to prefer the most specific constructor for a user defined struct type, so I can omit the JsonConstructor attributes which would add a dependency to the project where each such struct is defined.

I've reverse engineered a bit and implemented a custom contract resolver where I've overridden the CreateObjectContract method to add my custom creation logic.

public class CustomContractResolver : DefaultContractResolver {

var json = JsonConvert.SerializeObject(new Test(1, "Test"), new JsonSerializerSettings {

var t = JsonConvert.DeserializeObject<Test>(json);
t.A.ShouldEqual(1);
t.B.ShouldEqual("Test");

I have solve this problem by configuring the build path. Here are the steps that I followed: In eclipse.

1. create a folder and save the logj4 file in it.
2. Write click in the folder created and go to Build path.
3. Click on Add folder
4. Choose the folder created.
5. Click ok and Apply and close.

Now you should be able to run

Redux author here!

Redux is not that different from Flux. Overall it has same architecture, but Redux is able to cut some complexity corners by using functional composition where Flux uses callback registration.

There is not a fundamental difference in Redux, but I find it makes certain abstractions easier, or at least possible to implement, that would be hard or impossible to implement in Flux.

Reducer Composition

Take, for example, pagination. My Flux + React Router example handles pagination, but the code for that is awful. One of the reasons it's awful is that Flux makes it unnatural to reuse functionality across stores. If two stores need to handle pagination in response to different actions, they either need to inherit from a common base store (bad! you're locking yourself into a particular design when you use inheritance), or call an externally defined function from within the event handler, which will need to somehow operate on the Flux store's private state. The whole thing is messy (although definitely in the realm of possible).

On the other hand, with Redux pagination is natural thanks to reducer composition. It's reducers all the way down, so you can write a reducer factory that generates pagination reducers and then use it in your reducer tree. The key to why it's so easy is because in Flux, stores are flat, but in Redux, reducers can be nested via functional composition, just like React components can be nested.

This pattern also enables wonderful features like no-user-code undo/redo. Can you imagine plugging Undo/Redo into a Flux app being two lines of code? Hardly. With Redux, it is—again, thanks to reducer composition pattern. I need to highlight there's nothing new about it—this is the pattern pioneered and described in detail in Elm Architecture which was itself influenced by Flux.

Server Rendering

People have been rendering on the server fine with Flux, but seeing that we have 20 Flux libraries each attempting to make server rendering “easier”, perhaps Flux has some rough edges on the server. The truth is Facebook doesn't do much server rendering, so they haven't been very concerned about it, and rely on the ecosystem to make it easier.

In traditional Flux, stores are singletons. This means it's hard to separate the data for different requests on the server. Not impossible, but hard. This is why most Flux libraries (as well as the new Flux Utils) now suggest you use classes instead of singletons, so you can instantiate stores per request.

There are still the following problems that you need to solve in Flux (either yourself or with the help of your favorite Flux library such as Flummox or Alt):

• If stores are classes, how do I create and destroy them with dispatcher per request? When do I register stores?
• How do I hydrate the data from the stores and later rehydrate it on the client? Do I need to implement special methods for this?

Admittedly Flux frameworks (not vanilla Flux) have solutions to these problems, but I find them overcomplicated. For example, Flummox asks you to implement serialize() and deserialize() in your stores. Alt solves this nicer by providing takeSnapshot() that automatically serializes your state in a JSON tree.

Redux just goes further: since there is just a single store (managed by many reducers), you don't need any special API to manage the (re)hydration. You don't need to “flush” or “hydrate” stores—there's just a single store, and you can read its current state, or create a new store with a new state. Each request gets a separate store instance. Read more about server rendering with Redux.

Again, this is a case of something possible both in Flux and Redux, but Flux libraries solve this problem by introducing a ton of API and conventions, and Redux doesn't even have to solve it because it doesn't have that problem in the first place thanks to conceptual simplicity.

Developer Experience

I didn't actually intend Redux to become a popular Flux library—I wrote it as I was working on my ReactEurope talk on hot reloading with time travel. I had one main objective: make it possible to change reducer code on the fly or even “change the past” by crossing out actions, and see the state being recalculated.

I haven't seen a single Flux library that is able to do this. React Hot Loader also doesn't let you do this—in fact it breaks if you edit Flux stores because it doesn't know what to do with them.

When Redux needs to reload the reducer code, it calls replaceReducer(), and the app runs with the new code. In Flux, data and functions are entangled in Flux stores, so you can't “just replace the functions”. Moreover, you'd have to somehow re-register the new versions with the Dispatcher—something Redux doesn't even have.

Ecosystem

Redux has a rich and fast-growing ecosystem. This is because it provides a few extension points such as middleware. It was designed with use cases such as logging, support for Promises, Observables, routing, immutability dev checks, persistence, etc, in mind. Not all of these will turn out to be useful, but it's nice to have access to a set of tools that can be easily combined to work together.

Simplicity

Redux preserves all the benefits of Flux (recording and replaying of actions, unidirectional data flow, dependent mutations) and adds new benefits (easy undo-redo, hot reloading) without introducing Dispatcher and store registration.

Keeping it simple is important because it keeps you sane while you implement higher-level abstractions.

Unlike most Flux libraries, Redux API surface is tiny. If you remove the developer warnings, comments, and sanity checks, it's 99 lines. There is no tricky async code to debug.

You can actually read it and understand all of Redux.

See also my answer on downsides of using Redux compared to Flux.

you might want to use force with push operation in this case

git push origin master --force

I believe you are looking for the query functions, isBefore, isSame, and isAfter.

But it's a bit difficult to tell exactly what you're attempting. Perhaps you are just looking to get the difference between the input time and the current time? If so, consider the difference function, diff. For example:

moment().diff(date_time, 'minutes')

A few other things:

• There's an error in the first line:

    var date_time = 2013-03-24 + 'T' + 10:15:20:12 + 'Z'
  

  That's not going to work. I think you meant:

    var date_time = '2013-03-24' + 'T' + '10:15:20:12' + 'Z';
  

  Of course, you might as well:

    var date_time = '2013-03-24T10:15:20:12Z';
  

• You're using: .tz('UTC') incorrectly. .tz belongs to moment-timezone. You don't need to use that unless you're working with other time zones, like America/Los_Angeles.

  If you want to parse a value as UTC, then use:

    moment.utc(theStringToParse)
  

  Or, if you want to parse a local value and convert it to UTC, then use:

    moment(theStringToParse).utc()
  

  Or perhaps you don't need it at all. Just because the input value is in UTC, doesn't mean you have to work in UTC throughout your function.

• You seem to be getting the "now" instance by moment(new Date()). You can instead just use moment().

Updated

Based on your edit, I think you can just do this:

var date_time = req.body.date + 'T' + req.body.time + 'Z';
var isafter = moment(date_time).isAfter('2014-03-24T01:14:00Z');

Or, if you would like to ensure that your fields are validated to be in the correct format:

var m = moment.utc(req.body.date + ' ' + req.body.time, "YYYY-MM-DD  HH:mm:ss");
var isvalid = m.isValid();
var isafter = m.isAfter('2014-03-24T01:14:00Z');

expression is your friend:

plot(1,1, main=expression('title'^2))  #superscript
plot(1,1, main=expression('title'[2])) #subscript

How you can reproduce this cryptic error on the Ubuntu terminal:

Put this in a file called Main.java:

public Main{
    public static void main(String[] args){
        System.out.println("ok");
    }
}

Then compile it like this:

user@defiant /home/user $ javac Main
error: Class names, 'Main', are only accepted if 
annotation processing is explicitly requested
1 error

It's because you didn't specify .java at the end of Main.

Do it like this, and it works:

user@defiant /home/user $ javac Main.java
user@defiant /home/user $

Slap your forehead now and grumble that the error message is so cryptic.

There's a good discussion of this issue here.

I ran into the same architectural problem: wanting a way of giving my application more organization and internal namespaces, without:

• mixing application modules with external dependencies or bothering with private npm repos for application-specific code
• using relative requires, which make refactoring and comprehension harder
• using symlinks or changing the node path, which can obscure source locations and don't play nicely with source control

In the end, I decided to organize my code using file naming conventions rather than directories. A structure would look something like:

• npm-shrinkwrap.json
• package.json
• node_modules
  • ...
• src
  • app.js
  • app.config.js
  • app.models.bar.js
  • app.models.foo.js
  • app.web.js
  • app.web.routes.js
  • ...

Then in code:

var app_config = require('./app.config');
var app_models_foo = require('./app.models.foo');

or just

var config = require('./app.config');
var foo = require('./app.models.foo');

and external dependencies are available from node_modules as usual:

var express = require('express');

In this way, all application code is hierarchically organized into modules and available to all other code relative to the application root.

The main disadvantage is of course that in a file browser, you can't expand/collapse the tree as though it was actually organized into directories. But I like that it's very explicit about where all code is coming from, and it doesn't use any 'magic'.

static inner class: can declare static & non static members but can only access static members of its parents class.

non static inner class: can declare only non static members but can access static and non static member of its parent class.

If you are running puppet it may set /proc/sys/kernel/modules_disabled to 1, inhibiting further module loading. When the machine is reboot, it gets set back to 0, allowing for changes, such as loading the iptables modules. After a certain amount of time puppet will set it back to 1 to protect the system from kernel root kits. Therefore, whatever modules that we are going to need should be loaded during or shortly after boot time.

I think you declared the Equals method like this:

public override bool Equals(BOX obj)

Since the object.Equals method takes an object, there is no method to override with this signature. You have to override it like this:

public override bool Equals(object obj)

If you want type-safe Equals, you can implement IEquatable<BOX>.

No one has explained that you can dynamically define classes. So you can have a decorator that defines (and returns) a subclass:

def addId(cls):

    class AddId(cls):

        def __init__(self, id, *args, **kargs):
            super(AddId, self).__init__(*args, **kargs)
            self.__id = id

        def getId(self):
            return self.__id

    return AddId

Which can be used in Python 2 (the comment from Blckknght which explains why you should continue to do this in 2.6+) like this:

class Foo:
    pass

FooId = addId(Foo)

And in Python 3 like this (but be careful to use super() in your classes):

@addId
class Foo:
    pass

So you can have your cake and eat it - inheritance and decorators!

This appears in the context of the Handle-Body-Idiom, also called Pimpl idiom. It allows one to keep the ABI (binary interface) of a library the same, by keeping actual data into another class object, which is merely referenced by a pointer held in an "handle" object, consisting of functions that delegate to that class "Body".

It's also useful to enable constant time and exception safe swap of two objects. For this, merely the pointer pointing to the body object has to be swapped.

I know in the question you state "I assume JavaScript is used to create this effect" but CSS can be used too, an example is below.

CSS

.fancy-link {
   color: #333333;
   text-decoration: none;
   transition: color 0.3s linear;
   -webkit-transition: color 0.3s linear;
   -moz-transition: color 0.3s linear;
}

.fancy-link:hover {
   color: #F44336;
}

HTML

<a class="fancy-link" href="#">My Link</a>

And here is a JSFIDDLE for the above code!

Marcel in one of the answers points out you can "transition multiple CSS properties" you can also use "all" to effect the element with all your :hover styles like below.

CSS

.fancy-link {
   color: #333333;
   text-decoration: none;
   transition: all 0.3s linear;
   -webkit-transition: all 0.3s linear;
   -moz-transition: all 0.3s linear;
}

.fancy-link:hover {
   color: #F44336;
   padding-left: 10px;
}

HTML

<a class="fancy-link" href="#">My Link</a>

And here is a JSFIDDLE for the "all" example!

1. If both of your fields are datetime then simply adding those will work.

   eg:

   Declare @d datetime, @t datetime
   set @d = '2009-03-12 00:00:00.000';
   set @t = '1899-12-30 12:30:00.000';
   select @d + @t
   

2. If you used Date & Time datatype then just cast the time to datetime

   eg:

   Declare @d date, @t time
   set @d = '2009-03-12';
   set @t = '12:30:00.000';
   select @d + cast(@t as datetime)
   

I just wanted to add, Apache Commons IO has stream support utilities to perform the copy. (Btw, what do you mean by placing the file into an inputstream? Can you show us your code?)

Edit:

Okay, what do you want to do with the contents of the item? There is an item.get() which returns the entire thing in a byte array.

Edit2

item.getSize() will return the uploaded file size.

in /etc/my.cnf:

[mysqld]
...

performance_schema = 0

table_cache = 0
table_definition_cache = 0
max-connect-errors = 10000

query_cache_size = 0
query_cache_limit = 0

...

Good work on server with 256MB Memory.

If you want first 2 letters and last 2 letters of a string then you can use the following code: name = "India" name[0:2]="In" names[-2:]="ia"

Typing in 0% takes you to the beginning.

100% takes you to the end.

50% takes you half way.

Lets think your response is "successData". This contains a list which you need to add as options in a dropdown menu.

success: function (successData) {
var sizeOfData = successData.length;
if (sizeOfData == 0) {
    //    NO DATA, throw an alert ...
    alert ("No Data Found");
} else {
    $.each(successData, function(val, text) {
        mySelect.append(
            $('<option></option>').val(val).html(text)
        );
    });
} }

This would work for you ....

You can also use System.lineSeparator():

String x = "Hello," + System.lineSeparator() + "there";

SELECT COUNT(*) FROM information_schema.tables

The subject of the certificate is the entity its public key is associated with (i.e. the "owner" of the certificate).

As RFC 5280 says:

The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension.

X.509 certificates have a Subject (Distinguished Name) field and can also have multiple names in the Subject Alternative Name extension.

The Subject DN is made of multiple relative distinguished names (RDNs) (themselves made of attribute assertion values) such as "CN=yourname" or "O=yourorganization".

In the context of the article you're linking to, the subject would be the user/owner of the cert.

Rather than provide you with a complete list of differences, I'll give you my view on the matter.

If you read carefully the wiki page you provide, you'll often see sentences like "Octave supports both, while MATLAB requires the first" etc. This shows that Octave's developers try to make Octave syntax "superior" to MATLAB's.

This attitude makes Octave lose its purpose completely. The idea behind Octave is (or has become, I should say, see comments below) to have an open source alternative to run m-code. If it tries to be "better", it thus tries to be different, which is not in line with the reasons most people use it for. In my experience, running stuff developed in MATLAB doesn't ever work in one go, except for the really simple, really short stuff -- For any sizable function, I always have to translate a lot of stuff before it works in Octave, if not re-write it from scratch. How this is better, I really don't see...

Also, if you learn Octave, there's a lot of syntax allowed in Octave that's not allowed in MATLAB. Meaning -- code written in Octave often does not work in MATLAB without numerous conversions. It's also not compatible the other way around!

I could go on: The MathWorks has many toolboxes for MATLAB, there's Simulink and its related products for which there really is no equivalent in Octave (yes, you'd have to pay for all that. But often your employer/school does that anyway, and well, it at least exists), proven compliance with several industry standards, testing tools, validation tools, requirement management systems, report generation, a much larger community & user base, etc. etc. etc. MATLAB is only a small part of something much larger. Octave is...just Octave.

So, my advice:

• Find out if your school will pay for MATLAB. Often they will.
• If they don't, and if you can scrape together the money, buy MATLAB and learn to use it properly. In the long run it's the better decision.
• If you really can't get the money -- use Octave, but learn MATLAB's syntax and stay away from Octave-only syntax. (see note)

Why this last point? Because in the sciences, there are often large code bases entirely written in MATLAB. There are professors, engineers, students, professional coders, lots and lots of people who know all the intricate gory details of MATLAB, and not so much of Octave.

If you get a new job, and everyone in your new office speaks Spanish, it's kind of cocky to demand of everyone that they start speaking English from then on, simply because you don't speak/like Spanish. Same with MATLAB and Octave.

NB -- if all downvoters could just leave a comment with their arguments and reasons for disagreeing with me, that'd be great :)

Note: Octave can be run in "traditional mode" (by including the --traditional flag when starting Octave) which makes it give an error when certain Octave-only syntax is used.

Use position:fixed; and set the top:0;left:0;right:0;height:100px; and you should be able to have it "stick" to the top of the page.

<div style="position:fixed;top:0;left:0;right:0;height:100px;">Some buttons</div>

Here you can access "set2" property following:

    var obj = {
        "set1": [1, 2, 3],
        "set2": [4, 5, 6, 7, 8],
        "set3": [9, 10, 11, 12]
    };

    var output = Object.keys(obj)[1];

Object.keys return all the keys of provided object as Array..

@Min and @Max are used for validating numeric fields which could be String(representing number), int, short, byte etc and their respective primitive wrappers.

@Size is used to check the length constraints on the fields.

As per documentation @Size supports String, Collection, Map and arrays while @Min and @Max supports primitives and their wrappers. See the documentation.

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

This might be impossible or at least very hard. The DLL's contents don't depend (a lot) on it being written in C++; it's all machine code. That code might have been optimized so a lot of information that was present in the original source code is simply gone.

That said, here is one article that goes through a lot of material about doing this.

INDEX is a performance optimization technique that speeds up the data retrieval process. It is a persistent data structure that associated with a Table (or View) in order to increase performance during retrieving the data from that table (or View).

Index based search is applied more particularly when your queries include WHERE filter. Otherwise, i.e, a query without WHERE-filter selects whole data and process. Searching whole table without INDEX is called Table-scan.

You will find exact information for Sql-Indexes in clear and reliable way: follow these links:

UPDATE TABLE
   SET EndDate = CAST('2017-12-31' AS DATE)
 WHERE Id = '123'

Another way around it that may/may not suit but surely the simplest:

td {
    display: table-caption;
}

Your error is caused by these:

Dim oTable As Table, oRow As Row,

These types, Table and Row are not variable types native to Excel. You can resolve this in one of two ways:

1. Include a reference to the Microsoft Word object model. Do this from Tools | References, then add reference to MS Word. While not strictly necessary, you may like to fully qualify the objects like Dim oTable as Word.Table, oRow as Word.Row. This is called early-binding.
2. Alternatively, to use late-binding method, you must declare the objects as generic Object type: Dim oTable as Object, oRow as Object. With this method, you do not need to add the reference to Word, but you also lose the intellisense assistance in the VBE.

I have not tested your code but I suspect ActiveDocument won't work in Excel with method #2, unless you properly scope it to an instance of a Word.Application object. I don't see that anywhere in the code you have provided. An example would be like:

Sub DeleteEmptyRows()
Dim wdApp as Object
Dim oTable As Object, As Object, _
TextInRow As Boolean, i As Long

Set wdApp = GetObject(,"Word.Application")

Application.ScreenUpdating = False

For Each oTable In wdApp.ActiveDocument.Tables

In HTML, SGML and XML, ⁽¹⁾ attributes cannot be repeated, and should only be defined in an element once.

So your example:

<span style="color:blue" style="font-style:italic">Test</span>

is non-conformant to the HTML standard, and will result in undefined behaviour, which explains why different browsers are rendering it differently.

Since there is no defined way to interpret this, browsers can interpret it however they want and merge them, or ignore them as they wish.

^{(1): Every article I can find states that attributes are "key/value" pairs or "attribute-value" pairs, heavily implying the keys must be unique. The best source I can find states:}

^{Attribute names (id and status in this example) are subject to the same restrictions as other names in XML; they need not be unique across the whole DTD, however, but only within the list of attributes for a given element. (Emphasis mine.)}

Best option is to disable sorting and just feed data with desired sort order (from database or other source). Try to add this to your 'datatable': "bSort": false

numpy.random.randint accepts a third argument (size) , in which you can specify the size of the output array. You can use this to create your DataFrame -

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

Here - np.random.randint(0,100,size=(100, 4)) - creates an output array of size (100,4) with random integer elements between [0,100) .

Demo -

import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

which produces:

     A   B   C   D
0   45  88  44  92
1   62  34   2  86
2   85  65  11  31
3   74  43  42  56
4   90  38  34  93
5    0  94  45  10
6   58  23  23  60

You are overwriting your object file runexp.o by running this command :

 gcc -o runexp.o scd.o data_proc.o -lm -fopenmp

In fact, the -o is for the output file. You need to run :

gcc -o runexp.out runexp.o scd.o data_proc.o -lm -fopenmp

runexp.out will be you binary file.
