If you use same color for whole program , you can define printf() function.

   #include<stdio.h>
   #define ah_red "\e[31m"
   #define printf(X) printf(ah_red "%s",X);
   #int main()
   {
        printf("Bangladesh");
        printf("\n");
        return 0;
   }

Those integer types are all defined in stdint.h

You are correct in that glibc uses symbol versioning. If you are curious, the symbol versioning implementation introduced in glibc 2.1 is described here and is an extension of Sun's symbol versioning scheme described here.

One option is to statically link your binary. This is probably the easiest option.

You could also build your binary in a chroot build environment, or using a glibc-new => glibc-old cross-compiler.

According to the http://www.trevorpounds.com blog post Linking to Older Versioned Symbols (glibc), it is possible to to force any symbol to be linked against an older one so long as it is valid by using the same .symver pseudo-op that is used for defining versioned symbols in the first place. The following example is excerpted from the blog post.

The following example makes use of glibc’s realpath, but makes sure it is linked against an older 2.2.5 version.

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

__asm__(".symver realpath,realpath@GLIBC_2.2.5");
int main()
{
    const char* unresolved = "/lib64";
    char resolved[PATH_MAX+1];

    if(!realpath(unresolved, resolved))
        { return 1; }

    printf("%s\n", resolved);

    return 0;
}

x86 is rather broad range of devices.

For totally generic x86 target, an assembly block with "rep movsd" could blast out zeros to memory 32-bits at time. Try to make sure the bulk of this work is DWORD aligned.

For chips with mmx, an assembly loop with movq could hit 64bits at a time.

You might be able to get a C/C++ compiler to use a 64-bit write with a pointer to a long long or _m64. Target must be 8 byte aligned for the best performance.

for chips with sse, movaps is fast, but only if the address is 16 byte aligned, so use a movsb until aligned, and then complete your clear with a loop of movaps

Win32 has "ZeroMemory()", but I forget if thats a macro to memset, or an actual 'good' implementation.

You should use the ANSI functions for reading a line, eg. fgets. After calling you need free() in calling context, eg:

...
const char *entirecontent=readLine(myFile);
puts(entirecontent);
free(entirecontent);
...

const char *readLine(FILE *file)
{
  char *lineBuffer=calloc(1,1), line[128];

  if ( !file || !lineBuffer )
  {
    fprintf(stderr,"an ErrorNo 1: ...");
    exit(1);
  }

  for(; fgets(line,sizeof line,file) ; strcat(lineBuffer,line) )
  {
    if( strchr(line,'\n') ) *strchr(line,'\n')=0;
    lineBuffer=realloc(lineBuffer,strlen(lineBuffer)+strlen(line)+1);
    if( !lineBuffer )
    {
      fprintf(stderr,"an ErrorNo 2: ...");
      exit(2);
    }
  }
  return lineBuffer;
}

In my case , I had wrote really two times an entity of same type . So I delete it and all things work correctly

For SQL Developer

You have to execute it manually

SET SERVEROUTPUT ON 

After that if you execute any procedure with DBMS_OUTPUT.PUT_LINE('info'); or directly .

This will print the line

And please don't try to add this

 SET SERVEROUTPUT ON

inside the definition of function and procedure, it will not compile and will not work.

You might find a use for the methods method which returns an array of methods for an object. It's not the same as print_r, but still useful at times.

>> "Hello".methods.sort
=> ["%", "*", "+", "<", "<<", "<=", "<=>", "==", "===", "=~", ">", ">=", "[]", "[]=", "__id__", "__send__", "all?", "any?", "between?", "capitalize", "capitalize!", "casecmp", "center", "chomp", "chomp!", "chop", "chop!", "class", "clone", "collect", "concat", "count", "crypt", "delete", "delete!", "detect", "display", "downcase", "downcase!", "dump", "dup", "each", "each_byte", "each_line", "each_with_index", "empty?", "entries", "eql?", "equal?", "extend", "find", "find_all", "freeze", "frozen?", "grep", "gsub", "gsub!", "hash", "hex", "id", "include?", "index", "inject", "insert", "inspect", "instance_eval", "instance_of?", "instance_variable_defined?", "instance_variable_get", "instance_variable_set", "instance_variables", "intern", "is_a?", "is_binary_data?", "is_complex_yaml?", "kind_of?", "length", "ljust", "lstrip", "lstrip!", "map", "match", "max", "member?", "method", "methods", "min", "next", "next!", "nil?", "object_id", "oct", "partition", "private_methods", "protected_methods", "public_methods", "reject", "replace", "respond_to?", "reverse", "reverse!", "rindex", "rjust", "rstrip", "rstrip!", "scan", "select", "send", "singleton_methods", "size", "slice", "slice!", "sort", "sort_by", "split", "squeeze", "squeeze!", "strip", "strip!", "sub", "sub!", "succ", "succ!", "sum", "swapcase", "swapcase!", "taguri", "taguri=", "taint", "tainted?", "to_a", "to_f", "to_i", "to_s", "to_str", "to_sym", "to_yaml", "to_yaml_properties", "to_yaml_style", "tr", "tr!", "tr_s", "tr_s!", "type", "unpack", "untaint", "upcase", "upcase!", "upto", "zip"]

The quickest and easiest way to fix this is to do a find and replace on your date seperator, with the same separator. For example in this case Find "-" and Replace with "-", not sure why this works but you will find all dates are right-aligned as they should be after doing this.

Yes!

Here you have another example:

UPDATE prices
SET final_price= CASE
   WHEN currency=1 THEN 0.81*final_price
   ELSE final_price
END

This works because MySQL doesn't update the row, if there is no change, as mentioned in docs:

If you set a column to the value it currently has, MySQL notices this and does not update it.

If you want to use a command line program, but are not restricted to using SQL, you can use SchemaCrawler. SchemaCrawler is open source, and can produce files in plain text, CSV, or (X)HTML formats.

You can also use the built-in forensic log feature.

I enabled Trust Server Certificate in the Connection Properties and it worked for me

I used the below code to redirect to new page

Gmail: OAuth

• Goto the link
• Login with your gmail username password
• Click on the google menu at the top left
• Click API Manager
• Click on Credentials
• Click Create Credentials and select OAuth Client
• Select Web Application as Application type and Enter the Name-> Enter Authorised Redirect URL (Eg: http://localhost:53922/signin-google) ->Click on Create button. This will create the credentials. Pls make a note of Client ID and Secret ID. Finally click OK to close the credentials pop up.
• Next important step is to enable the Google API. Click on Overview in the left pane.
• Click on the Google API under Social APIs section.
• Click Enable.

That’s all from the Google part.

Come back to your application, open App_start/Startup.Auth.cs and uncomment the following snippet

        app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
        {
            ClientId = "",
            ClientSecret = ""
        });

Update the ClientId and ClientSecret with the values from Google API credentials which you have created already.

• Run your application
• Click Login
• You will see the Google button under ‘Use Another Section to log in’ section
• Click on the Google button
• Application will prompt you to enter the username and password
• Enter the gmail username and password and click Sign In
• This will perform the OAuth and come back to your application and prompting you to register with the Gmail id.
• Click register to register the Gmail id into your application database.
• You will see the Identity details appear in the top as normal registration
• Try logout and login again thru Gmail. This will automatically logs you into the app.

So first of all, pandas updates using the index. When an update command does not update anything, check both left-hand side and right-hand side. If you don't update the indices to follow your identification logic, you can do something along the lines of

>>> df.loc[df.filename == 'test2.dat', 'n'] = df2[df2.filename == 'test2.dat'].loc[0]['n']
>>> df
Out[331]: 
    filename   m     n
0  test0.dat  12  None
1  test2.dat  13    16

If you want to do this for the whole table, I suggest a method I believe is superior to the previously mentioned ones: since your identifier is filename, set filename as your index, and then use update() as you wanted to. Both merge and the apply() approach contain unnecessary overhead:

>>> df.set_index('filename', inplace=True)
>>> df2.set_index('filename', inplace=True)
>>> df.update(df2)
>>> df
Out[292]: 
            m     n
filename           
test0.dat  12  None
test2.dat  13    16

Using absolute as position is not responsive + mobile friendly. I would suggest using a div with a background-image and then placing text in the div will place text over the image. Depending on your html, you might need to use height with vh value

I'd like to provide an answer for the case that you do not have control over the code that opens the connection. Like I did when using the URLClassLoader to load a jar file from a password protected server.

The Authenticator solution would work but has the drawback that it first tries to reach the server without a password and only after the server asks for a password provides one. That's an unnecessary roundtrip if you already know the server would need a password.

public class MyStreamHandlerFactory implements URLStreamHandlerFactory {

    private final ServerInfo serverInfo;

    public MyStreamHandlerFactory(ServerInfo serverInfo) {
        this.serverInfo = serverInfo;
    }

    @Override
    public URLStreamHandler createURLStreamHandler(String protocol) {
        switch (protocol) {
            case "my":
                return new MyStreamHandler(serverInfo);
            default:
                return null;
        }
    }

}

public class MyStreamHandler extends URLStreamHandler {

    private final String encodedCredentials;

    public MyStreamHandler(ServerInfo serverInfo) {
        String strCredentials = serverInfo.getUsername() + ":" + serverInfo.getPassword();
        this.encodedCredentials = Base64.getEncoder().encodeToString(strCredentials.getBytes());
    }

    @Override
    protected URLConnection openConnection(URL url) throws IOException {
        String authority = url.getAuthority();
        String protocol = "http";
        URL directUrl = new URL(protocol, url.getHost(), url.getPort(), url.getFile());

        HttpURLConnection connection = (HttpURLConnection) directUrl.openConnection();
        connection.setRequestProperty("Authorization", "Basic " + encodedCredentials);

        return connection;
    }

}

This registers a new protocol my that is replaced by http when credentials are added. So when creating the new URLClassLoader just replace http with my and everything is fine. I know URLClassLoader provides a constructor that takes an URLStreamHandlerFactory but this factory is not used if the URL points to a jar file.

You can try Tsuru. Tsuru is a opensource PaaS inspired in Heroku, and it is already with some products in production at Globo.com(internet arm of the biggest Broadcast Television Company in Brazil)

It manages the entire flow of an application, since the container creation, deploy, routing(with hipache) with many nice features as docker cluster, scaling of units, segregated deploy, etc.

Take a look in our documentation bellow: http://docs.tsuru.io/

Here our post covering our environment: http://blog.tsuru.io/2014/04/04/running-tsuru-in-production-scaling-and-segregating-docker-containers/

I Have a Query With This result :

If you ever need to delete all the indexes, this may come in handy:

curl -X DELETE 'http://localhost:9200/_all'

Powershell:

Invoke-WebRequest -method DELETE http://localhost:9200/_all

I needed to get the element as a string.

jQuery("#bob").get(0).outerHTML;

Which will give you something like:

<input type="text" id="bob" value="hello world" />

...as a string rather than a DOM element.

Problems only surface when I am I trying to give the first loaded content an active state

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current');

First option (bad because of throw-catch, but MS will do work for you):

        return true;
    }
    catch {

    }
}

Visual Studio Community is same (almost) as professional edition. What differs is that VS community do not have TFS features, and the licensing is different. As stated by @Stefan.

The different versions on VS are compared here - https://www.visualstudio.com/en-us/products/compare-visual-studio-2015-products-vs

To figure out if an Integer is greater than 0, you can:

• check if compareTo(O) returns a positive number:

  if (count.compareTo(0) > 0)
       ...
  

  But that looks pretty silly, doesn't it? Better just...

• use autoboxing¹:

  if (count > 0)
      ....
  

  This is equivalent to:

  if (count.intValue() > 0)
      ...
  

  It is important to note that "==" is evaluated like this, with the Integer operand unboxed rather than the int operand boxed. Otherwise, count == 0 would return false when count was initialized as new Integer(0) (because "==" tests for reference equality).

¹Technically, the first example uses autoboxing (before Java 1.5 you couldn't pass an int to compareTo) and the second example uses unboxing. The combined feature is often simply called "autoboxing" for short, which is often then extended into calling both types of conversions "autoboxing". I apologize for my lax usage of terminology.

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

I wanted also to check if a remote file exist but with RSH. I have tried the previous solutions but they didn't work with RSH.

Finally, I did I short function which works fine:

function existRemoteFile ()
{
REMOTE=$1
FILE=$2
RESULT=$(rsh -l user $REMOTE  "test -e $FILE && echo \"0\" || echo \"1\"")
if [ $RESULT -eq 0 ]
then
    return 0
else
    return 1
fi
}

You'll find debugging errors like this a lot easier if you catch any errors thrown from the execSQL call. eg:

 try 
 {
      db.execSQL(Create_CashBook);  
 }
 catch (Exception e) 
 {
       Log.e("ERROR", e.toString());
 }

I recently discovered a couple of image tracing libraries for JavaScript that indeed are able to build an acceptable approximation to the bitmap, both size and quality. I'm developing this JavaScript library and CLI :

https://www.npmjs.com/package/svg-png-converter

Which provides unified API for all of them, supporting browser and node, non depending on DOM, and a Command line tool.

For converting logos/cartoon/like images it does excellent job. For photos / realism some tweaking is needed since the output size can grow a lot.

It has a playground although right now I'm working on a better one, easier to use, since more features has been added:

There is a Python 2 implementation by odiak.

I liked qiao's first answer very much! The only thing missing here is to mark the vertexes as visited.

Why we need to do it?
Lets imagine that there is another node number 13 connected from node 11. Now our goal is to find node 13.
After a little bit of a run the queue will look like this:

[[1, 2, 6], [1, 3, 10], [1, 4, 7], [1, 4, 8], [1, 2, 5, 9], [1, 2, 5, 10]]

Note that there are TWO paths with node number 10 at the end.
Which means that the paths from node number 10 will be checked twice. In this case it doesn't look so bad because node number 10 doesn't have any children.. But it could be really bad (even here we will check that node twice for no reason..)
Node number 13 isn't in those paths so the program won't return before reaching to the second path with node number 10 at the end..And we will recheck it..

All we are missing is a set to mark the visited nodes and not to check them again..
This is qiao's code after the modification:

graph = {
    1: [2, 3, 4],
    2: [5, 6],
    3: [10],
    4: [7, 8],
    5: [9, 10],
    7: [11, 12],
    11: [13]
}


def bfs(graph_to_search, start, end):
    queue = [[start]]
    visited = set()

    while queue:
        # Gets the first path in the queue
        path = queue.pop(0)

        # Gets the last node in the path
        vertex = path[-1]

        # Checks if we got to the end
        if vertex == end:
            return path
        # We check if the current node is already in the visited nodes set in order not to recheck it
        elif vertex not in visited:
            # enumerate all adjacent nodes, construct a new path and push it into the queue
            for current_neighbour in graph_to_search.get(vertex, []):
                new_path = list(path)
                new_path.append(current_neighbour)
                queue.append(new_path)

            # Mark the vertex as visited
            visited.add(vertex)


print bfs(graph, 1, 13)

The output of the program will be:

[1, 4, 7, 11, 13]

Without the unneccecery rechecks..

Sorry, it is a reponse to an old thread, but might still be usefull.

In addition to above reponses, This genrally happens when two columns with same name, even from different tables are included in the same query. for example if we joining two tables city and state where tables have column name e.g. city.name and state.name. when such a query is added to the dataset, ssrs removes the table name or the table alias and only keeps the name, whih eventually appears twice in the query and errors as duplicate key. The best way to avoid it is to use alias such as calling the column names city.name as c_name state.name as s_name. This will resolve the issue.

It will just sleep the thread except in the case where your application has only a single thread, in which case it will sleep the thread and effectively the process as well.

The python documentation on sleep doesn't specify this however, so I can certainly understand the confusion!

http://docs.python.org/2/library/time.html

I have a solution based on @Cherniv's answer (works on macOS for me). Two differences: I have a Main2Activity.java in the java folder that I do the same thing to, and I don't bother calling ./gradlew clean since it seems like the react-native packager does that automatically anyways.

Anyways, my solution does what Cherniv's does, except I made a bash shell script for it since I'm building multiple apps using one set of code and want to be able to easily change the package name whenever I run my npm scripts.

Here is the bash script I used. You'll need to modify the packageName you want to use, and add anything else you want to it... but here are the basics. You can create a .sh file, give permission, and then run it from the same folder you run react-native from:

rm -rf ./android/app/src/main/java


mkdir -p ./android/app/src/main/java/com/MyWebsite/MyAppName
    packageName="com.MyWebsite.MyAppName"
    sed -i '' -e "s/.*package.*/package "$packageName";/" ./android/app/src/main/javaFiles/Main2Activity.java
    sed -i '' -e "s/.*package.*/package "$packageName";/" ./android/app/src/main/javaFiles/MainActivity.java
    sed -i '' -e "s/.*package.*/package "$packageName";/" ./android/app/src/main/javaFiles/MainApplication.java
    sed -i '' -e "s/.*package=\".*/    package=\""$packageName"\"/" ./android/app/src/main/AndroidManifest.xml
    sed -i '' -e "s/.*package = '.*/  package = '"$packageName"',/" ./android/app/BUCK
    sed -i '' -e "s/.*applicationId.*/    applicationId \""$packageName"\"/" ./android/app/build.gradle

    cp -R ./android/app/src/main/javaFiles/ ./android/app/src/main/java/com/MyWebsite/MyAppName

DISCLAIMER: You'll need to edit MainApplication.java's comment near the bottom of the java file first. It has the word 'package' in the comment. Because of how the script works, it takes any line with the word 'package' in it and replaces it. Because of this, this script may not be future proofed as there might be that same word used somewhere else.

Second Disclaimer: the first 3 sed commands edit the java files from a directory called javaFiles. I created this directory myself since I want to have one set of java files that are copied from there (as I might add new packages to it in the future). You will probably want to do the same thing. So copy all the files from the java folder (go through its subfolders to find the actual java files) and put them in a new folder called javaFiles.

Third Disclaimer: You'll need to edit the packageName variable to be in line with the paths at the top of the script and bottom (com.MyWebsite.MyAppName to com/MyWebsite/MyAppName)

Use

git apply patchfile

if possible.

patch -p1 < patchfile 

has potential side-effect.

git apply also handles file adds, deletes, and renames if they're described in the git diff format, which patch won't do. Finally, git apply is an "apply all or abort all" model where either everything is applied or nothing is, whereas patch can partially apply patch files, leaving your working directory in a weird state.

There is an Extension Manager extension, that may help. It seems to allow to install a set of extensions specified in the settings.json.

You will get rejection message from apple just because the product you have registered for inApp purchase might come under category Non-renewing subscriptions and consumable products. These type of products will not automatically renewable. you need to have explicit restore button in your application.

for other type of products it will automatically restore it.

Please read following text which will clear your concept about this :

Once a transaction has been processed and removed from the queue, your application normally never sees it again. However, if your application supports product types that must be restorable, you must include an interface that allows users to restore these purchases. This interface allows a user to add the product to other devices or, if the original device was wiped, to restore the transaction on the original device.

Store Kit provides built-in functionality to restore transactions for non-consumable products, auto-renewable subscriptions and free subscriptions. To restore transactions, your application calls the payment queue’s restoreCompletedTransactions method. The payment queue sends a request to the App Store to restore the transactions. In return, the App Store generates a new restore transaction for each transaction that was previously completed. The restore transaction object’s originalTransaction property holds a copy of the original transaction. Your application processes a restore transaction by retrieving the original transaction and using it to unlock the purchased content. After Store Kit restores all the previous transactions, it notifies the payment queue observers by calling their paymentQueueRestoreCompletedTransactionsFinished: method.

If the user attempts to purchase a restorable product (instead of using the restore interface you implemented), the application receives a regular transaction for that item, not a restore transaction. However, the user is not charged again for that product. Your application should treat these transactions identically to those of the original transaction. Non-renewing subscriptions and consumable products are not automatically restored by Store Kit. Non-renewing subscriptions must be restorable, however. To restore these products, you must record transactions on your own server when they are purchased and provide your own mechanism to restore those transactions to the user’s devices

Just my 2 cents. The following command fails if called from batch file (Windows 7) placed on pendrive:

xcopy /s /e /i %cd%Ala C:\KS\Ala

But this does the job:

xcopy /s /e /i %~dp0Ala C:\KS\Ala

Swift 5: Here is a cool and easy extension to remove elements in an array, without filtering :

   extension Array where Element: Equatable {

    // Remove first collection element that is equal to the given `object`:
    mutating func remove(object: Element) {
        guard let index = firstIndex(of: object) else {return}
        remove(at: index)
    }

}

Usage :

var myArray = ["cat", "barbecue", "pancake", "frog"]
let objectToRemove = "cat"

myArray.remove(object: objectToRemove) // ["barbecue", "pancake", "frog"]

Also works with other types, such as Int since Element is a generic type:

var myArray = [4, 8, 17, 6, 2]
let objectToRemove = 17

myArray.remove(object: objectToRemove) // [4, 8, 6, 2]

Cant do this without aliasing , simply because, how are you going to reference a field in the where clause, if that field exists in the 2 or 3 tables you are joining? It will be unclear for mysql which one you are trying to reference.

Maybe your mobile view port is not set. Add following meta tag inside <head></head> to allow menu to work on mobiles.

I usually do the following:

:Check_Architecture
if /i "%processor_architecture%"=="x86" (
    IF NOT DEFINED PROCESSOR_ARCHITEW6432 (
        REM Run 32 bit command

    ) ELSE (
        REM Run 64 bit command
    )           
) else (
        REM Run 64 bit command
)

Just simply write BETWEEN '{$startDate}' AND '{$endDate}' in where condition as

->where("date BETWEEN '{$startDate}' AND '{$endDate}'")

FYI I just tested this and the stack trace reported by 'throw;' is not an entirely correct stack trace. Example:

    private void foo()
    {
        try
        {
            bar(3);
            bar(2);
            bar(1);
            bar(0);
        }
        catch(DivideByZeroException)
        {
            //log message and rethrow...
            throw;
        }
    }

    private void bar(int b)
    {
        int a = 1;
        int c = a/b;  // Generate divide by zero exception.
    }

The stack trace points to the origin of the exception correctly (reported line number) but the line number reported for foo() is the line of the throw; statement, hence you cannot tell which of the calls to bar() caused the exception.

The default collation for stored procedure parameters is utf8_general_ci and you can't mix collations, so you have four options:

Option 1: add COLLATE to your input variable:

SET @rUsername = ‘aname’ COLLATE utf8_unicode_ci; -- COLLATE added
CALL updateProductUsers(@rUsername, @rProductID, @rPerm);

Option 2: add COLLATE to the WHERE clause:

CREATE PROCEDURE updateProductUsers(
    IN rUsername VARCHAR(24),
    IN rProductID INT UNSIGNED,
    IN rPerm VARCHAR(16))
BEGIN
    UPDATE productUsers
        INNER JOIN users
        ON productUsers.userID = users.userID
        SET productUsers.permission = rPerm
        WHERE users.username = rUsername COLLATE utf8_unicode_ci -- COLLATE added
        AND productUsers.productID = rProductID;
END

Option 3: add it to the IN parameter definition:

CREATE PROCEDURE updateProductUsers(
    IN rUsername VARCHAR(24) COLLATE utf8_unicode_ci, -- COLLATE added
    IN rProductID INT UNSIGNED,
    IN rPerm VARCHAR(16))
BEGIN
    UPDATE productUsers
        INNER JOIN users
        ON productUsers.userID = users.userID
        SET productUsers.permission = rPerm
        WHERE users.username = rUsername
        AND productUsers.productID = rProductID;
END

Option 4: alter the field itself:

ALTER TABLE users CHARACTER SET utf8 COLLATE utf8_general_ci;

Unless you need to sort data in Unicode order, I would suggest altering all your tables to use utf8_general_ci collation, as it requires no code changes, and will speed sorts up slightly.

UPDATE: utf8mb4/utf8mb4_unicode_ci is now the preferred character set/collation method. utf8_general_ci is advised against, as the performance improvement is negligible. See https://stackoverflow.com/a/766996/1432614

Your function shouldn't take vector<int>*; it should take vector<int>::iterator or vector<int>::const_iterator as appropriate. Then, just pass in foo.begin() + 1.

On Edge

if(!NodeList.prototype.forEach) {
  NodeList.prototype.forEach = function(fn, scope) {
    for(var i = 0, len = this.length; i < len; ++i) {
      fn.call(scope, this[i], i, this);
    }
  }
}

The => operator is used to assign key-value pairs in an associative array. For example:

$fruits = array(
  'Apple'  => 'Red',
  'Banana' => 'Yellow'
);

It's meaning is similar in the foreach statement:

foreach ($fruits as $fruit => $color)
  echo "$fruit is $color in color.";

It's a buzzword that refers to things like the normal Web architecture with e.g., Javascript - ASP.Net - Middleware - Database layer. Each of these things is a "tier".

Initialization is not require in case of zero because default value of int in Java is zero. For values other than zero java.util.Arrays provides a number of options, simplest one is fill method.

int[] arr = new int[5];
Arrays.fill(arr, -1);
System.out.println(Arrays.toString(arr));  //[-1, -1, -1, -1, -1 ]

int [] arr = new int[5];
// fill value 1 from index 0, inclusive, to index 3, exclusive
Arrays.fill(arr, 0, 3, -1 )
System.out.println(Arrays.toString(arr)); // [-1, -1, -1, 0, 0]

We can also use Arrays.setAll() if we want to fill value on condition basis:

int[] array = new int[20];
Arrays.setAll(array, p -> p > 10 ? -1 : p);

int[] arr = new int[5];
Arrays.setAll(arr, i -> i);
System.out.println(Arrays.toString(arr));   // [0, 1, 2, 3, 4]

Use a 9-patch drawable or create a Shape drawable.

This works for me in Windows:

print chr(12)

One thing that got this working for me is to make sure that github.com is in ~jenkins/.ssh/known_hosts.

Everyone is right. You can't print an int[] object out directly, but there's also no need to not use an ArrayList of integer arrays.

Using,

Arrays.toString(arl.get(0))

means splitting the String object into a substring if you want to insert anything in between, such as commas.

Here's what I think amv was looking for from an int array viewpoint.

System.out.println("Arraylist contains: " 
    + arl.get(0)[0] + ", " 
    + arl.get(0)[1] + ", " 
    + arl.get(0)[2]);

This answer is a little late for amv but still may be useful to others.

If you have a file in your repo that it is supposed to be customized by most pullers, then rename the file to something like config.php.template and add config.php to your .gitignore.

Just check the implementation of source code by command click:

    private void initWindowDecorActionBar() {
    Window window = getWindow();

    // Initializing the window decor can change window feature flags.
    // Make sure that we have the correct set before performing the test below.
    window.getDecorView();

    if (isChild() || !window.hasFeature(Window.FEATURE_ACTION_BAR) || mActionBar != null) {
        return;
    }

    mActionBar = new WindowDecorActionBar(this);
    mActionBar.setDefaultDisplayHomeAsUpEnabled(mEnableDefaultActionBarUp);

    mWindow.setDefaultIcon(mActivityInfo.getIconResource());
    mWindow.setDefaultLogo(mActivityInfo.getLogoResource());
}

requestWindowFeature(Window.FEATURE_ACTION_BAR); Fixed my issue as I saw requestWindowFeature(Window.FEATURE_ACTION_BAR) is failing; code is open source use it !!

Using pathlib you can get the folder in which the current file is located. __file__ is the pathname of the file from which the module was loaded. Ref: docs

import pathlib

current_dir = pathlib.Path(__file__).parent
current_file = pathlib.Path(__file__)

Doc ref: link

You can create a script to switch from versions: sudo nano switch_php then type this:

#!/bin/sh
#!/bin/bash
echo "Switching to PHP$1..."
case $1 in
    "7")
        sudo a2dismod php5.6
        sudo a2enmod php7.0
        sudo service apache2 restart
        sudo ln -sfn /usr/bin/php7.0 /etc/alternatives/php;;
    "5.6")
        sudo a2dismod php7.0
        sudo a2enmod php5.6
        sudo service apache2 restart
        sudo ln -sfn /usr/bin/php5.6 /etc/alternatives/php;;
esac
echo "Current version: $( php -v | head -n 1 | cut -c-7 )"

exit and save make it executable: sudo chmod +x switch_php

To execute the script just type ./switch_php [VERSION_NUMBER] where the parameter is 7 or 5.6

That's it you can now easily switch form PHP7 to PHP 5.6!

Instead of having to create a function in the ts file you can toggle a variable from the template itself. You can then use the variable to apply a specific class to the element. Like so-

<div (click)="status=!status"  
    [ngClass]="status ? 'success' : 'danger'">                
     Some content
</div>

So when status is true the class success is applied. When it is false danger class is applied.

This will work without any additional code in the ts file.

In my case (php 5.6, Ubuntu 14.04) the following command worked for me:

sudo apt-get install php5.6-gd

According to php version we need to change the php5.x-gd

I guess this is simple way to check palindrome

String strToRevrse = "MOM";

strToRevrse.equalsIgnoreCase(new StringBuilder(strToRevrse).reverse().toString());

You would do

Person.where('name=? OR lastname=?', 'John', 'Smith')

Right now, there isn't any other OR support by the new AR3 syntax (that is without using some 3rd party gem).

The simple way is to create table as textfile and move the file to the appropriate location

CREATE EXTERNAL TABLE mytable(col1 string, col2 string)
row format delimited fields terminated by '|' stored as textfile;

Copy the file to the HDFS Location where table is created.
Hope this helps!!!

Here are some vendors you might me looking for

::-webkit-input-placeholder {color: tomato}
::-moz-placeholder          {color: tomato;} /* Firefox 19+ */
:-moz-placeholder           {color: tomato;} /* Firefox 18- */
:-ms-input-placeholder      {color: tomato;}

You can also style different states, such as focus

:focus::-webkit-input-placeholder {color: transparent}
:focus::-moz-placeholder          {color: transparent}
:focus:-moz-placeholder           {color: transparent}
:focus:-ms-input-placeholder      {color: transparent}

You can also do certain transitions on it, like

::-VENDOR-input-placeholder       {text-indent: 0px;   transition: text-indent 0.3s ease;}
:focus::-VENDOR-input-placeholder  {text-indent: 500px; transition: text-indent 0.3s ease;}

Emails require tables in order to work properly.

Inky (by foundation for emails) is a templating language that converts simple HTML tags into the complex table HTML required for emails.

Example

<html>

<head></head>

<body>
  <table align="center" class="container">
    <tbody>
      <tr>
        <td>
          <table class="row">
            <tbody>
              <tr>
                <th class="small-12 large-12 columns first last">
                  <table>
                    <tbody>
                      <tr>
                        <th>Put content in me!</th>
                        <th class="expander"></th>
                      </tr>
                    </tbody>
                  </table>
                </th>
              </tr>
            </tbody>
          </table>&zwj;
        </td>
      </tr>
    </tbody>
  </table>
</body>

According to the certification exam you should use Convert.ToXXX() whenever possible for simple conversions because it optimizes performance better than CXXX conversions.

You can flip both vertical and horizontal at the same time

    -moz-transform: scaleX(-1) scaleY(-1);
    -o-transform: scaleX(-1) scaleY(-1);
    -webkit-transform: scaleX(-1) scaleY(-1);
    transform: scaleX(-1) scaleY(-1);

And with the transition property you can get a cool flip

    -webkit-transition: transform .4s ease-out 0ms;
    -moz-transition: transform .4s ease-out 0ms;
    -o-transition: transform .4s ease-out 0ms;
    transition: transform .4s ease-out 0ms;
    transition-property: transform;
    transition-duration: .4s;
    transition-timing-function: ease-out;
    transition-delay: 0ms;

Actually it flips the whole element, not just the background-image

You can use the following regex to replace non-ASCII characters

str = str.replace(/[^A-Za-z 0-9 \.,\?""!@#\$%\^&\*\(\)-_=\+;:<>\/\\\|\}\{\[\]`~]*/g, '')

However, note that spaces, colons and commas are all valid ASCII, so the result will be

> str
"INFO] :, , ,  (Higashikurume)"

On GKE, if the pod is dead, it's best to check for the events. It will show in more detail what the error is about.

In my case, I had :

Failed to pull image "gcr.io/project/imagename@sha256:c8e91af54fc17faa1c49e2a05def5cbabf8f0a67fc558eb6cbca138061a8400a":
 rpc error: code = Unknown desc = error pulling image configuration: unknown blob

It turned out the image was damaged somehow. After repushing it and deploying with the new hash, it worked again.

Here is an answer to the literal meaning of the title rather than the body of this question:

import time
import datetime
import random

def date_to_timestamp(d) :
  return int(time.mktime(d.timetuple()))

def randomDate(start, end):
  """Get a random date between two dates"""

  stime = date_to_timestamp(start)
  etime = date_to_timestamp(end)

  ptime = stime + random.random() * (etime - stime)

  return datetime.date.fromtimestamp(ptime)

This code is based loosely on the accepted answer.

For example :

In MainActivity :

Intent intent = new Intent(this, OtherActivity.class);
intent.putExtra(OtherActivity.KEY_EXTRA, yourDataObject);
startActivity(intent);

In OtherActivity :

public static final String KEY_EXTRA = "com.example.yourapp.KEY_BOOK";

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  String yourDataObject = null;

  if (getIntent().hasExtra(KEY_EXTRA)) {
      yourDataObject = getIntent().getStringExtra(KEY_EXTRA);
  } else {
      throw new IllegalArgumentException("Activity cannot find  extras " + KEY_EXTRA);
  }
  // do stuff
}

I recently had this issue and the clean/build etc. didn't resolve it. I guessed I had an issue somewhere but wasn't sure where to look to find it (was it in the manifest, resource xml files etc?).

When something is wrong, you can find out what it is by doing a code analysis run.

From the menu at the top choose:

Analyze -> Inspect code, scan the whole project using the 'Default' profile.

Your inspection results will contain an element called 'Android'. In here you will get a list of anything that is causing issues in your resources and manifest file. The errors will open up the generated xml files from your build which will show any errors in red.

My exact issue was caused because I was using flavour based manifest files and I copied some permissions inside the <application> tag in the flavour by accident.

UPDATE: I did have an issue after where Android Studio still showed the error after the fix, even though I could now build and run perfectly fine while the error was still there. (I am running a canary build so putting it down to that for now)

After looking more, the root element has to be associated with a schema-namespace as Blaise is noting. Yet, I didnt have a package-info java. So without using the @XMLSchema annotation, I was able to correct this issue by using

@XmlRootElement (name="RetrieveMultipleSetsResponse", namespace = XMLCodeTable.NS1)
@XmlType(name = "ns0", namespace = XMLCodeTable.NS1)
@XmlAccessorType(XmlAccessType.NONE)
public class RetrieveMultipleSetsResponse {//...}

Hope this helps!

My use case was I wanted to replace foo:/Drive_Letter with foo:/bar/baz/xyz In my case I was able to do it with the following code. I was in the same directory location where there were bulk of files.

find . -name "*.library" -print0 | xargs -0 sed -i '' -e 's/foo:\/Drive_Letter:/foo:\/bar\/baz\/xyz/g'

hope that helped.

MySQL WorkBench is free software and is developed by Oracle, you can import an SQL File or specify a database and it will generate an SQL Diagram which you can move around to make it more visually appealing. It runs on GNU/Linux and Windows and it's free and has a professional look..

Previous answers got you list of torch.Size Here is how to get list of ints

Ref and event bus both has issues when your control render is affected by v-if. So, I decided to go with a simpler method.

The idea is using an array as a queue to send methods that needs to be called to the child component. Once the component got mounted, it will process this queue. It watches the queue to execute new methods.

(Borrowing some code from Desmond Lua's answer)

Parent component code:

import ChildComponent from './components/ChildComponent'

new Vue({
  el: '#app',
  data: {
    item: {},
    childMethodsQueue: [],
  },
  template: `
  <div>
     <ChildComponent :item="item" :methods-queue="childMethodsQueue" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.childMethodsQueue.push({name: ChildComponent.methods.save.name, params: {}})
    }
  },
  components: { ChildComponent },
})

This is code for ChildComponent

<template>
 ...
</template>

<script>
export default {
  name: 'ChildComponent',
  props: {
    methodsQueue: { type: Array },
  },
  watch: {
    methodsQueue: function () {
      this.processMethodsQueue()
    },
  },
  mounted() {
    this.processMethodsQueue()
  },
  methods: {
    save() {
        console.log("Child saved...")

    processMethodsQueue() {
      if (!this.methodsQueue) return
      let len = this.methodsQueue.length
      for (let i = 0; i < len; i++) {
        let method = this.methodsQueue.shift()

And there is a lot of room for improvement like moving processMethodsQueue to a mixin...

I've just solved this exact problem on my Ubuntu 14.04 with Eclipse Mars 2.

This could happen when Eclipse is not finding Tomcat's configuration files where they are expected to be. This place is in

$eclipse_workspace_folder/$version_of_your_tomcat_server_at_localhost/

(by default if you didn't changed server's name). So you have to copy all the files under your $tomcat_installation_folder/conf/* to the workspace server's folder.

But it was easier to just remove the server from your server list and add it again. Eclipse will automatically recreate all these files again into the proper folders. Like in the picture below:

In my case I've downloaded tomcat-8.0.35 from the website, so the configuration files needed are in /opt/apache-tomcat-8.0.35/conf/ filesystem.

Just delete the desired server from the Servers view (Window -> Show View -> Servers) and then go to Window -> Preferences -> Server -> Runtime Environment -> Add and add the server again.

Try

SELECT EXTRACTVALUE(xmltype(testclob), '/DCResponse/ContextData/Field[@key="Decision"]') 
FROM traptabclob;

Here is a sqlfiddle demo

Check my sample solution

<h5 style="float: left; width: 50%;">Employee: Employee Name</h5>
<h5 style="float: right; width: 50%; text-align: right;">Employee: Employee Name</h5>

This will divide your page into two and insert the two header elements to the right and left part equally.

DAO is an act like as "Persistence Manager " in 3 tier architecture as well as DAO also design pattern as you can consult "Gang of Four" book. Your application service layer just need to call the method of DAO class without knowing hidden & internal details of DAO's method.

In your servlet context listener contextDestroyed() method, manually deregister the drivers:

// This manually deregisters JDBC driver, which prevents Tomcat 7 from complaining about memory leaks wrto this class
Enumeration<Driver> drivers = DriverManager.getDrivers();
while (drivers.hasMoreElements()) {
    Driver driver = drivers.nextElement();
    try {
        DriverManager.deregisterDriver(driver);
        LOG.log(Level.INFO, String.format("deregistering jdbc driver: %s", driver));
    } catch (SQLException e) {
        LOG.log(Level.SEVERE, String.format("Error deregistering driver %s", driver), e);
    }
}

Apache shows php code instead of executing Issue fixed

1. Opened php5.6 conf or php7.x conf

# following command:

$ sudo vi /etc/apache2/mods-enabled/php5.6.conf

2. Commented following lines

3. Restarted the server

$ sudo service apache2 restart

4 Enjoy :)

Here is a simple expressjs solution if you just want to run this app locally and security is not a concern:

On your server.js or app.js file, add the following:

app.use('/local-files', express.static('/'));

That will serve your ENTIRE root directory under /local-files. Needless to say this is a really bad idea if you're planning to deploy this app anywhere other than your local machine.

Now, you can simply do:

<img src="/local-files/images/mypic.jps"/> 

note: I'm running macOS. If you're using Windows you may have to search and remove 'C:\' from the path string

UPDATE:
To answer the API Error Code: 191
The redirect_uri should be equal (or relative) to the Site URL.

Tip: Use base URLs instead of full URLs pointing to specific pages.

NOT RECOMMENDED: For example, if you use www.mydomain.com/fb/test.html as your Site URL and having www.mydomain.com/fb/secondPage.html as redirect_uri this will give you the 191 error.

RECOMMENDED: So instead have your Site URL set to a base URL like: www.mydomain.com/ OR www.mydomain.com/fb/.

I went through the Facebook Python sample application today, and I was shocked it was stating clearly that you can use http://localhost:8080/ as Site URL if you are developing locally:

Configure the Site URL, and point it to your Web Server. If you're developing locally, you can use http://localhost:8080/

While I was sure you can't do that, based on my own experience (very old test though) it seems that you actually CAN test your Facebook application locally!

So I picked up an old application of mine and edited its name, Site URL and Canvas URL: Site URL: http://localhost:80/fblocal/

I downloaded the latest Facebook PHP-SDK and threw it in my xampp/htdocs/fblocal/ folder.

But I got the same error as yours! I noticed that XAMPP is doing an automatic redirection to http://localhost/fblocal/ so I changed the setting to simply http://localhost/fblocal/ and the error was gone BUT I had to remove the application (from privacy settings) and re-install my application and here are the results:

After that, asked for the publish_stream permission, and I was able to publish to my profile (using the PHP-SDK):

$user = $facebook->getUser();
if ($user) {
    try {
        $post = $facebook->api('/me/feed', 'post', array('message'=>'Hello World, from localhost!'));
    } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
    }
}

Results:

You have to put your .exe file's path into enviroment variable path. Go to "My computer -> properties -> advanced -> environment variables -> Path" and edit path by adding .exe's directory into path.

Another solution I personally prefer is using RapidEE for a smoother variable editing.

You need to follow the following steps:

Find line that read follows

Require ip 127.0.0.1

Replace with your workstation IP address:

Require ip 10.1.3.53

Again find the following line:

Allow from 127.0.0.1

Replace as follows:

Allow from 10.1.3.53

Also find deny from all and comment it in the entire file.

Save and close the file.Restart Apache httpd server:

# service httpd restart

Just my 2 cents on setting PHPSESSID cookie issue when on localhost and under dev environment. I make the AJAX call to my REST API endpoint on the locahost. Say its address is mysite.localhost/api/member/login/ (virtal host on my dev environment).

• When I do this request on Postman, things go fine and PHPSESSID is set with the response.

• When I request this endpoint via AJAX from the Browsersync proxied page (e.g. from 122.133.1.110:3000/test/api/login.php in my browser address line, see the domain is different vs mysite.localhost) PHPSESSID does not appear among cookies.

• When I make this request directly from the page on the same domain (i.e. mysite.localhost/test/api/login.php) PHPSESSID is set just fine.

So this is a cross-origin origin request cookies issue as mentioned in @flu answer above

There's a much simpler way to convert your XmlDocument to a string; use the OuterXml property. The OuterXml property returns a string version of the xml.

public string GetXMLAsString(XmlDocument myxml)
{
    return myxml.OuterXml;
}

It depends on the web application being loaded. Try some of the approaches below:

Set higher render priority (deprecated from API 18+):

webview.getSettings().setRenderPriority(RenderPriority.HIGH);

Enable/disable hardware acceleration:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    // chromium, enable hardware acceleration
    webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
} else {
    // older android version, disable hardware acceleration
    webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}

Disable the cache (if you have problems with your content):

webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

Here's some PowerShell code that should work. You can combine most of this into fewer lines, but I wanted to keep it clear and readable.

[string]$strippedFileName = [System.IO.Path]::GetFileNameWithoutExtension($filePath);

[string]$newFileName = $strippedFileName + [DateTime]::Now.ToString("yyyyMMdd-HHmmss") + $extension;
[string]$newFilePath = [System.IO.Path]::Combine($directory, $newFileName);

Move-Item -LiteralPath $filePath -Destination $newFilePath;

This article MEM10-C. Define and use a pointer validation function says it is possible to do a check to some degree, especially under Linux OS.

Although BETWEEN is easy to read and maintain, I rarely recommend its use because it is a closed interval and as mentioned previously this can be a problem with dates - even without time components.

For example, when dealing with monthly data it is often common to compare dates BETWEEN first AND last, but in practice this is usually easier to write dt >= first AND dt < next-first (which also solves the time part issue) - since determining last usually is one step longer than determining next-first (by subtracting a day).

In addition, another gotcha is that lower and upper bounds do need to be specified in the correct order (i.e. BETWEEN low AND high).

I had the same Problem. Just rename your .CPP file to other name and try it again. It worked for me.

Jwt is a strict set of instructions for the issuing and validating of signed access tokens. The tokens contain claims that are used by an app to limit access to a user

OAuth2 on the other hand is not a protocol, its a delegated authorization framework. think very detailed guideline, for letting users and applications authorize specific permissions to other applications in both private and public settings. OpenID Connect which sits on top of OAUTH2 gives you Authentication and Authorization.it details how multiple different roles, users in your system, server side apps like an API, and clients such as websites or native mobile apps, can authenticate with each othe

Note oauth2 can work with jwt , flexible implementation, extandable to different applications

Error:function round(double precision, integer) does not exist

Solution: You need to addtype cast then it will work

Ex: round(extract(second from job_end_time_t)::integer,0)

Sometimes even the simplest things can make a difference. One of these simple items that should be part of every stored procedure is SET NOCOUNT ON. This one line of code, put at the top of a stored procedure turns off the messages that SQL Server sends back to the client after each T-SQL statement is executed. This is performed for all SELECT, INSERT, UPDATE, and DELETE statements. Having this information is handy when you run a T-SQL statement in a query window, but when stored procedures are run there is no need for this information to be passed back to the client.

By removing this extra overhead from the network it can greatly improve overall performance for your database and application.

If you still need to get the number of rows affected by the T-SQL statement that is executing you can still use the @@ROWCOUNT option. By issuing a SET NOCOUNT ON this function (@@ROWCOUNT) still works and can still be used in your stored procedures to identify how many rows were affected by the statement.

You can use set the layout_width or layout_width to 0dp (By the orientation you want to fill remaining space). Then use the layout_weight to make it fill remaining space.

You shouldn't measure time in interval function. Instead just save time when timer was started and measure difference when timer was stopped/paused. Use setInterval only to update displayed value. So there is no need to pause timer and you will get best possible accuracy in this way.

There is no built-in functions to do that in Php (shame ^^). You want to compare a date string to today, you could use a simple substr to achieve it:

if (substr($timestamp, 0, 10) === date('Y.m.d')) { today }
elseif (substr($timestamp, 0, 10) === date('Y.m.d', strtotime('-1 day')) { yesterday }

No date conversion, simple.

if you want to delete the last line of the input file itself do

sed -i '' -e '$ d' foo.txt

CASE isn't used for flow control... for this, you would need to use IF...

But, there's a set-based solution to this problem instead of the procedural approach:

UPDATE tblEmployee
SET 
  InOffice = CASE WHEN @NewStatus = 'InOffice' THEN -1 ELSE InOffice END,
  OutOffice = CASE WHEN @NewStatus = 'OutOffice' THEN -1 ELSE OutOffice END,
  Home = CASE WHEN @NewStatus = 'Home' THEN -1 ELSE Home END
WHERE EmpID = @EmpID

Note that the ELSE will preserves the original value if the @NewStatus condition isn't met.

Try to make your css more specific so that the new (green) style is more specific than the previous one, so that it worked for me!

For example, you might use in css:

button:active {/*your style here*/}

Instead of (probably not working):

.active {/*style*/} (.active is not a pseudo-class)

Hope it helps!

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"

Most browsers can decompress gzip on the fly. That might be a better option than a javascript implementation.

Seems like you are looking for the Mode value (Statistical Mode) , have a look at Apache's Docs for Statistical functions.

Declare your TextView not clickable / focusable by using android:clickable="false" and android:focusable="false" or v.setClickable(false) and v.setFocusable(false). The click events should be dispatched to the TextView's parent now.

Note:

In order to achieve this, you have to add click to its direct parent. or set android:clickable="false" and android:focusable="false" to its direct parent to pass listener to further parent.

Matplotlib can handle directly and transparently jpg if you have installed PIL. You don't need to call it, it will do it by itself. If Python cannot find PIL, it will raise an error.

The translation you are addressing has to do with Map Projection, which is how the spherical surface of our world is translated into a 2 dimensional rendering. There are multiple ways (projections) to render the world on a 2-D surface.

If your maps are using just a specific projection (Mercator being popular), you should be able to find the equations, some sample code, and/or some library (e.g. one Mercator solution - Convert Lat/Longs to X/Y Co-ordinates. If that doesn't do it, I'm sure you can find other samples - https://stackoverflow.com/search?q=mercator. If your images aren't map(s) using a Mercator projection, you'll need to determine what projection it does use to find the right translation equations.

If you are trying to support multiple map projections (you want to support many different maps that use different projections), then you definitely want to use a library like PROJ.4, but again I'm not sure what you'll find for Javascript or PHP.

The other option is .cxx where the x is supposed to be a plus rotated 45°.

Windows, Mac and Linux all support .c++ so we should just use that.

On Microsoft Windows, gvim wouldn't allow you to select non-monospaced fonts. Unfortunately Latha is a non-monospaced font.

There is a hack way to make it happen: Using FontForge (you can download Windows binary from http://www.geocities.jp/meir000/fontforge/) to edit the Latha.ttf and mark it as a monospaced font. Doing like this:

1. Load fontforge, select latha.ttf.
2. Menu: Element -> Font Info
3. Select "OS/2" from left-hand list on Font Info dialog
4. Select "Panose" tab
5. Set Proportion = Monospaced
6. Save new TTF version of this font, try it out!

Good luck!

If you just need to check if some cookie exist then simple do this:

document.cookie.split('logged=true').length == 2

if cookie logged=true exist, you will get 2, if not 1.

logged=true - change this to you cookie name=value, or just a name

And if you are using python 3.X, you may apply the sorted function on the mylist. This is just an addition to the answer that @Sven Marnach has given above.

# using *sort method*
mylist.sort(lambda x: x[1]) 

# using *sorted function*
sorted(mylist, key = lambda x: x[1]) 

Create a custom reverseIterable.

In [1]: df
Out[1]:
   data
0     1
1     2
2     3
3     4

You want to apply a function that conditionally returns a value based on the selected dataframe column.

In [2]: df['data'].apply(lambda x: 'true' if x <= 2.5 else 'false')
Out[2]:
0     true
1     true
2    false
3    false
Name: data

You can then assign that returned column to a new column in your dataframe:

In [3]: df['desired_output'] = df['data'].apply(lambda x: 'true' if x <= 2.5 else 'false')

In [4]: df
Out[4]:
   data desired_output
0     1           true
1     2           true
2     3          false
3     4          false

The difference is that miniconda is just shipping the repository management system. So when you install it there is just the management system without packages. Whereas with Anaconda, it is like a distribution with some built in packages.

Like with any Linux distribution, there are some releases which bundles lots of updates for the included packages. That is why there is a difference in version numbering. If you only decide to upgrade Anaconda, you are updating a whole system.

BalusC excellent answer covers most of the patterns for web applications.

Some application may require Chain-of-responsibility_pattern

In object-oriented design, the chain-of-responsibility pattern is a design pattern consisting of a source of command objects and a series of processing objects. Each processing object contains logic that defines the types of command objects that it can handle; the rest are passed to the next processing object in the chain.

Use case to use this pattern:

When handler to process a request(command) is unknown and this request can be sent to multiple objects. Generally you set successor to object. If current object can't handle the request or process the request partially and forward the same request to successor object.

In PySpark 1.3 sort method doesn't take ascending parameter. You can use desc method instead:

from pyspark.sql.functions import col

(group_by_dataframe
    .count()
    .filter("`count` >= 10")
    .sort(col("count").desc()))

or desc function:

from pyspark.sql.functions import desc

(group_by_dataframe
    .count()
    .filter("`count` >= 10")
    .sort(desc("count"))

Both methods can be used with with Spark >= 1.3 (including Spark 2.x).

Call decode() on a bytes instance to get the text which it encodes.

str = bytes.decode()

Let we have the following 2 tables(salary and employee)

Now i want those records from employee table which are not in salary. We can do this in 3 ways:

1. Using inner Join

select * from employee
where id not in(select e.id from employee e inner join salary s on e.id=s.id)

2. Using Left outer join

select * from employee e 
left outer join salary s on e.id=s.id  where s.id is null

3. Using Full Join

select * from employee e
full outer join salary s on e.id=s.id where e.id not in(select id from salary)

Outside of character classes, it is conventional not to escape hyphens. If I saw an escaped hyphen outside of a character class, that would suggest to me that it was written by someone who was not very comfortable with regexes.

Inside character classes, I don't think one way is conventional over the other; in my experience, it usually seems to be to put either first or last, as in [-._:] or [._:-], to avoid the backslash; but I've also often seen it escaped instead, as in [._\-:], and I wouldn't call that unconventional.

Use insertHtml() or insertText() method.

<html lang="en">
<head>
<script>
function getDateDiff(time1, time2) {
  var str1= time1.split('/');
  var str2= time2.split('/');

  //                yyyy   , mm       , dd
  var t1 = new Date(str1[2], str1[0]-1, str1[1]);
  var t2 = new Date(str2[2], str2[0]-1, str2[1]);

  var diffMS = t1 - t2;    
  console.log(diffMS + ' ms');

  var diffS = diffMS / 1000;    
  console.log(diffS + ' ');

  var diffM = diffS / 60;

  var diffH = diffM / 60;

There are may be several different problems when you move your AVD or SDK to another directory, or replace an old SDK with a new one, or somehow get the SDK corrupted.

Below I'll describe all the possible problems I know, and will give you several ways to solve them.

Of course I assume that you have any AVD created, and it is located in C:\Users\<user_name>\.android\avd (Windows) or ~/.android/avd (Linux/MacOS).

If you moved .android to another place then set the ANDROID_SDK_HOME environment variable to the path of the parent dir containing your .android and make sure the AVD Manager successfully found your Virtual Device.

Also check paths in <user_home>/.android/avd/<avd_name>.ini

Incomplete/corrupted SDK stucture

PANIC: Cannot find AVD system path. Please define ANDROID_SDK_ROOT
PANIC: Broken AVD system path. Check your ANDROID_SDK_ROOT value

These 2 errors happen if the emulator cannot find the SDK, or the SDK is broken.

So, first of all I recommend to remove the ANDROID_SDK_ROOT variable at all. It's only needed when the emulator is located outside of the SDK directory. But in general, your emulator stays inside the SDK dir. And in this case it must detect the SDK location automatically. If it doesn't, then your SDK probably has wrong filetree. Please do the following:

1. Check that the SDK directory has at least these 4 directories: emulator, platforms, platform-tools, system-images. It is very important! These directories must be present. If some of them don't exist, then just create empty dirs.

2. Go to <user_home>/.android/avd/<avd_name> and open config.ini. Find the image.sysdir.1 property. It points at the directory, inside the SDK directory, that contains the actual system image. Make sure that this directory exists and contains files like build.prop, system.img, etc. If it doesn't, then you have to open the SDK Manager and download system images your AVD requires (see below).

If everything's set up properly, when these errors about ANDROID_SDK_ROOT must be gone. If they're not, then now you may try to set up ANDROID_SDK_ROOT variable.

Required packages and HAXM are not installed

The next problem you may face is that the emulator starts to launch, but hangs up or quits immediatelly. That probably means that you don't have all the required packages installed.

Another possible error is:

Could not automatically detect an ADB binary. Some emulator functionality will not work until a custom path to ADB is added in the extended settings page.

So, to successfully launch any AVD you must be sure that at least these packages are installed:

emulator (Android Emulator)
platform-tools (Android SDK Platform-Tools)
tools (Android SDK Tools)

And as I mentioned earlier you must install system images your AVD is using, for example system-images;android-25;google_apis;x86

Note that the most recent versions on SDK don't have a standalone SDK Manager.exe. Instead of it you have either to use Android Studio, or tools\bin\sdkmanager.bat (Linux/MacOS probably have sh files).

To list all available packages use sdkmanager --list or sdkmanager --list --verbose

To install packages use sdkmanager <package1> <package2> ...

Also I recommend to install HAXM on your system manually.

Qcow2-files refer to incorrect/nonexistent base-images

The last problem I'll mention happens when you're trying to move AVD or SDK from one computer or directory to another. In this case you may get such error:

qemu-system-i386.exe: -drive if=none,overlap-check=none,cache=unsafe,index=0,id=system,file=C:\Users\<old_user_name>\.android\avd\<avd_name>.

avd\system.img.qcow2,read-only: Could not open backing file: Could not open '<old_sdk_dir>\system-images\android-22\google_apis\x86\system.img': Invalid argument

There are 2 ways to fix it:

1. If you don't care about the data the AVD contains, just delete all the qcow2 files from the AVD directory (e.g. from <user_home>/.android/avd/<avd_name>). In this case you will get a clean version of Android, like after a hard reset.

2. If the data on the emulator is important to you, then open all qcow2 files one by one using any HEX editor (I prefer HxD), find the path of a base img file, and change it to the correct one in the Overwrite mode (to preserve the file size). Then select the path and get its length in hex (e.g. 2F). 2F represents the ASCII slash /. Put it into position 13:

PS: Not sure, but there are probably some utilites like qemu-img allowing to set different base image. Well, to me it's easier to manually edit the binary.

Now you'll probably be able to successfully launch your Android Virtual Device. I hope so :)

Any reason you cannot just change it on the object directly? It is not as if javascript enforces visibility of a property on an object.

The HTML code:

<input type="radio" name="theName" value="1" id="option-1">
<input type="radio" name="theName" value="2">
<input type="radio" name="theName" value="3">

The Javascript code:

$(document).ready(function(){
    $('input[name="theName"]').change(function(){
        if($('#option-1').prop('checked')){
            alert('Option 1 is checked!');
        }else{
            alert('Option 1 is unchecked!');
        }
    });
});

In multiple radio with name "theName", detect when option 1 is checked or unchecked. Works in all situations: on click control, use the keyboard, use joystick, automatic change the values from other dinamicaly function, etc.

Using the gedit text editor (3.18.3)

1. Click Search
2. Click Find and Replace...
3. Enter \n\s into Find field
4. Leave Replace with blank (nothing)
5. Check Regular expression box
6. Click the Find button

Note: this doesn't exactly address the OP's original, 7 year old problem but should help some noob linux users (like me) who find their way here from the SE's with similar "how do I get my text all on one line" questions.

Following are the build-in constants you can use as per your requirements for getting the paths in Codeigniter:

EXT: The PHP file extension

FCPATH: Path to the front controller (this file) (root of CI)

SELF: The name of THIS file (index.php)

BASEPATH: Path to the system folder

APPPATH: The path to the “application” folder

Thanks.

You don't need to do any complex command-line stuff or edit any system code. You simply have to open Computer, showing all of your disks and open properties. From there, go to Advanced System Settings and click Environment Variables. Scroll down in the lower list box and edit Path. Do not erase anything already there. Put a ; after it and then type in your path. To test, open command prompt and do "javac", it should list around 20 programs. You would be finished at that point.

By the way, the command to compile is javac -g not just javac.

Happy coding!

You can use disabled attribute to disable the textbox.

document.getElementById('color').disabled = true;

A simple technique is to put this somewhere in your index:

<div class="font_preload" style="opacity: 0">
    <span style="font-family: 'myfontface#1font-family', Arial, sans-serif;"></span>
    <span style="font-family: 'myfontface#2font-family', Arial, sans-serif;"></span>
    ...
</div>

Tested on Chrome 34, Safari 7 and FF 29 and IE 11

I was still confused after reading the other answers and comments. But the answer now seems simpler, so here you go.

Since Pandas version 0.9 (from 2012), you can read your csv with empty cells interpreted as empty strings by simply setting keep_default_na=False:

pd.read_csv('test.csv', keep_default_na=False)

This issue is more clearly explained in

• More consistent na_values handling in read_csv · Issue #1657 · pandas-dev/pandas

That was fixed on on Aug 19, 2012 for Pandas version 0.9 in

• BUG: more consistent na_values #1657 · pandas-dev/pandas@d9abf68

Write all your code below this 2 lines:-

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

It worked for me without re-installing again.

I am an operating system that only allocates you memory in 10mb partitions.

Internal Fragmentation

• You ask for 17mb of memory
• I give you 20mb of memory

Fulfilling this request has just led to 3mb of internal fragmentation.

External Fragmentation

• You ask for 20mb of memory
• I give you 20mb of memory
• The 20mb of memory that I give you is not immediately contiguous next to another existing piece of allocated memory. In so handing you this memory, I have "split" a single unallocated space into two spaces.

Fulfilling this request has just led to external fragmentation

I recently wrote for powershell several functions for communicating with FTP, see https://github.com/AstralisSomnium/PowerShell-No-Library-Just-Functions/blob/master/FTPModule.ps1. The second function below, you can send a whole local folder to FTP. In the module are even functions for removing / adding / reading folders and files recursively.

#Add-FtpFile -ftpFilePath "ftp://myHost.com/folder/somewhere/uploaded.txt" -localFile "C:\temp\file.txt" -userName "User" -password "pw"
function Add-FtpFile($ftpFilePath, $localFile, $username, $password) {
    $ftprequest = New-FtpRequest -sourceUri $ftpFilePath -method ([System.Net.WebRequestMethods+Ftp]::UploadFile) -username $username -password $password
    Write-Host "$($ftpRequest.Method) for '$($ftpRequest.RequestUri)' complete'"
    $content = $content = [System.IO.File]::ReadAllBytes($localFile)
    $ftprequest.ContentLength = $content.Length
    $requestStream = $ftprequest.GetRequestStream()
    $requestStream.Write($content, 0, $content.Length)
    $requestStream.Close()
    $requestStream.Dispose()
}

#Add-FtpFolderWithFiles -sourceFolder "C:\temp\" -destinationFolder "ftp://myHost.com/folder/somewhere/" -userName "User" -password "pw"
function Add-FtpFolderWithFiles($sourceFolder, $destinationFolder, $userName, $password) {
    Add-FtpDirectory $destinationFolder $userName $password
    $files = Get-ChildItem $sourceFolder -File
    foreach($file in $files) {
        $uploadUrl ="$destinationFolder/$($file.Name)"
        Add-FtpFile -ftpFilePath $uploadUrl -localFile $file.FullName -username $userName -password $password
    }
}

#Add-FtpFolderWithFilesRecursive -sourceFolder "C:\temp\" -destinationFolder "ftp://myHost.com/folder/" -userName "User" -password "pw"
function Add-FtpFolderWithFilesRecursive($sourceFolder, $destinationFolder, $userName, $password) {
    Add-FtpFolderWithFiles -sourceFolder $sourceFolder -destinationFolder $destinationFolder -userName $userName -password $password
    $subDirectories = Get-ChildItem $sourceFolder -Directory
    $fromUri = new-object System.Uri($sourceFolder)
    foreach($subDirectory in $subDirectories) {
        $toUri  = new-object System.Uri($subDirectory.FullName)
        $relativeUrl = $fromUri.MakeRelativeUri($toUri)
        $relativePath = [System.Uri]::UnescapeDataString($relativeUrl.ToString())
        $lastFolder = $relativePath.Substring($relativePath.LastIndexOf("/")+1)
        Add-FtpFolderWithFilesRecursive -sourceFolder $subDirectory.FullName -destinationFolder "$destinationFolder/$lastFolder" -userName $userName -password $password
    }
}

var is_chrome = /chrome/.test( navigator.userAgent.toLowerCase() );

You can use this function, which creates a tempfile in the filesystem and returns the path to the downloaded file if everything worked fine:

function getFileContents($url)
{
    // Workaround: Save temp file
    $img = tempnam(sys_get_temp_dir(), 'pdf-');
    $img .= '.' . pathinfo($url, PATHINFO_EXTENSION);

    $fp = fopen($img, 'w+');

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FILE, $fp);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

    $result = curl_exec($ch);
    curl_close($ch);

    fclose($fp);

    return $result ? $img : false;
}

Your k^th FFT result's frequency is 2*pi*k/N.

Just to share, I've developed my own script to do it. Feel free to use it. It generates "SELECT" statements that you can then run on the tables to generate the "INSERT" statements.

A boilerplate is a unit of writing that can be reused over and over without change. By extension, the idea is sometimes applied to reusable programming, as in “boilerplate code

A Java Date is a container for the number of milliseconds since January 1, 1970, 00:00:00 GMT.

When you use something like System.out.println(date), Java uses Date.toString() to print the contents.

The only way to change it is to override Date and provide your own implementation of Date.toString(). Now before you fire up your IDE and try this, I wouldn't; it will only complicate matters. You are better off formatting the date to the format you want to use (or display).

Java 8+

LocalDateTime ldt = LocalDateTime.now().plusDays(1);
DateTimeFormatter formmat1 = DateTimeFormatter.ofPattern("yyyy-MM-dd", Locale.ENGLISH);
System.out.println(ldt);
// Output "2018-05-12T17:21:53.658"

String formatter = formmat1.format(ldt);
System.out.println(formatter);
// 2018-05-12

Prior to Java 8

You should be making use of the ThreeTen Backport

The following is maintained for historical purposes (as the original answer)

What you can do, is format the date.

Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, 1);
SimpleDateFormat format1 = new SimpleDateFormat("yyyy-MM-dd");
System.out.println(cal.getTime());
// Output "Wed Sep 26 14:23:28 EST 2012"

String formatted = format1.format(cal.getTime());
System.out.println(formatted);
// Output "2012-09-26"

System.out.println(format1.parse(formatted));
// Output "Wed Sep 26 00:00:00 EST 2012"

These are actually the same date, represented differently.

You can use setTableId((short)100). I think this was changed in Java 5 so that numeric literals assigned to byte or short and within range for the target are automatically assumed to be the target type. That latest J2ME JVMs are derived from Java 4 though.

First() is causing this if your select returns 0 rows. You either have to catch that exception, or use FirstOrDefault() which will return null in case of no elements.

No, they are identical.

default(), for any value type (DateTime is a value type) will always call the parameterless constructor.

Usually, an Alpine Linux image doesn't contain bash, Instead you can use /bin/ash, /bin/sh, ash or only sh.

/bin/ash

docker run -it --rm alpine /bin/ash

/bin/sh

docker run -it --rm alpine /bin/sh

ash

docker run -it --rm alpine ash

sh

docker run -it --rm alpine sh

I hope this information helps you.

git gc --aggressive is one way to force the prune process to take place (to be sure: git gc --aggressive --prune=now). You have other commands to clean the repo too. Don't forget though, sometimes git gc alone can increase the size of the repo!

It can be also used after a filter-branch, to mark some directories to be removed from the history (with a further gain of space); see here. But that means nobody is pulling from your public repo. filter-branch can keep backup refs in .git/refs/original, so that directory can be cleaned too.

Finally, as mentioned in this comment and this question; cleaning the reflog can help:

git reflog expire --all --expire=now
git gc --prune=now --aggressive

An even more complete, and possibly dangerous, solution is to remove unused objects from a git repository

Update Feb. 2021, eleven years later: the new git maintenance command (man page) should supersede git gc, and can be scheduled.

This should give you the result you want.

double total = 0;
int number = 0;
float percentage = number / total * 100
printf("%.2f",percentage);

Note that the first operand is a double

TL;DR Use absolute paths to your assets (including your complete hostname) by setting your output.publicPath to e.g. "http://example.com/assets/".

The problem

The problem is the way that URLs are resolved by Chrome when they're parsed from a dynamically loaded CSS blob.

When you load the page, the browser loads your Webpack bundle entry JavaScript file, which (when you're using the style-loader) also contains a Base64 encoded copy of your CSS, which gets loaded into the page.

This is what it looks like in Chrome DevTools

That's fine for all the images or fonts which are encoded into the CSS as data URIs (i.e. the content of the file is embedded in the CSS), but for assets referenced by URL, the browser has to find and fetch the file.

Now by default the file-loader (which url-loader delegates to for large files) will use relative URLs to reference assets - and that's the problem!

These are the URLs generated by file-loader by default - relative URLs

When you use relative URLs, Chrome will resolve them relative to the containing CSS file. Ordinarily that's fine, but in this case the containing file is at blob://... and any relative URLs are referenced the same way. The end result is that Chrome attempts to load them from the parent HTML file, and ends up trying to parse the HTML file as the content of the font, which obviously won't work.

The Solution

Force the file-loader to use absolute paths including the protocol ("http" or "https").

Change your webpack config to include something equivalent to:

{
  output: {
    publicPath: "http://localhost:8080/", // Development Server
    // publicPath: "http://example.com/", // Production Server
  }
}

Now the URLs that it generates will look like this:

Absolute URLs!

These URLs will be correctly parsed by Chrome and every other browser.

Using extract-text-webpack-plugin

It's worth noting that if you're extracting your CSS to a separate file, you won't have this problem because your CSS will be in a proper file and URLs will be correctly resolved.

You can use docker-compose run instead of docker-compose up and tack the arguments on the end. For example:

docker-compose run dperson/samba arg1 arg2 arg3

If you need to connect to other docker containers, use can use --service-ports option:

docker-compose run --service-ports dperson/samba arg1 arg2 arg3

For me I doing this:

import paramiko
hostname = 'my hostname or IP' 
myuser   = 'the user to ssh connect'
mySSHK   = '/path/to/sshkey.pub'
sshcon   = paramiko.SSHClient()  # will create the object
sshcon.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # no known_hosts error
sshcon.connect(hostname, username=myuser, key_filename=mySSHK) # no passwd needed

works for me pretty ok

Your updateVelocity() method is missing the explicit self parameter in its definition.

Should be something like this:

def updateVelocity(self):    
    for x in range(0,len(self.velocity)):
        self.velocity[x] = 2*random.random()*(self.pbestx[x]-self.current[x]) + 2 \
          * random.random()*(self.gbest[x]-self.current[x])

Your other methods (except for __init__) have the same problem.

glibc internal implementation

glibc 2.28 has an internal implementation:

• stdio-common/_itoa.c
• sysdeps/generic/_itoa.h

which is used in several places internally, but I could not find if it can be exposed or how.

At least that should be a robust implementation if you are willing to extract it.

This question asks how to roll your own: How to convert an int to string in C?

I found out I made a mistake. There's no need to call toObject() or toJSON() at all. The __proto__ in the question came from jquery, not mongoose. Here's my test:

UserModel.find({}, function (err, users) {
    console.log(users.save);    // { [Function] numAsyncPres: 0 }
    var json = JSON.stringify(users);
    users = users.map(function (user) {
        return user.toObject();
    }
    console.log(user.save);    // undefined
    console.log(json == JSON.stringify(users));    // true
}

doc.toObject() removes doc.prototype from a doc. But it makes no difference in JSON.stringify(doc). And it's not needed in this case.

You can store the size somewhere, or you can have a struct with a special value set that you use as a sentinel, the same way that '\0' indicates the end of a string.

Why don't you try the fadeIn() instead of using a show() with delay(). I think what you are trying to do can be done with this. Here is the jQuery code for fadeIn and FadeOut() which also has inbuilt method for delaying the process.

$(document).ready(function(){
   $('element').click(function(){
      //effects take place in 3000ms
      $('element_to_hide').fadeOut(3000);
      $('element_to_show').fadeIn(3000);
   });
}

http://en.wikipedia.org/wiki/Collation

Collation is the assembly of written information into a standard order. (...) A collation algorithm such as the Unicode collation algorithm defines an order through the process of comparing two given character strings and deciding which should come before the other.

Try this, at the end of the each loop, ids array will contain all the hexcodes.

var ids = [];

    $(document).ready(function($) {
    var $div = $("<div id='hexCodes'></div>").appendTo(document.body), code;
    $(".color_cell").each(function() {
        code = $(this).attr('id');
        ids.push(code);
        $div.append(code + "<br />");
    });



});

According to php.net the Salt option has been deprecated as of PHP 7.0.0, so you should use the salt that is generated by default and is far more simpler

Example for store the password:

$hashPassword = password_hash("password", PASSWORD_BCRYPT);

Example to verify the password:

$passwordCorrect = password_verify("password", $hashPassword);

I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

INCLUDE_DIRECTORIES(your/header/dir)
LINK_DIRECTORIES(your/library/dir)
rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)

note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them

Use the Get-ChildItem cmdlet with the -Recurse switch:

Get-ChildItem -Path V:\Myfolder -Filter CopyForbuild.bat -Recurse -ErrorAction SilentlyContinue -Force

The one I use (it is a class member):

const MAX_LEVEL = 5; // change it as needed

public function arrayToObject($a, $level=0)
{

    if(!is_array($a)) {
        throw new InvalidArgumentException(sprintf('Type %s cannot be cast, array expected', gettype($a)));
    }

    if($level > self::MAX_LEVEL) {
        throw new OverflowException(sprintf('%s stack overflow: %d exceeds max recursion level', __METHOD__, $level));
    }

    $o = new stdClass();
    foreach($a as $key => $value) {
        if(is_array($value)) { // convert value recursively
            $value = $this->arrayToObject($value, $level+1);
        }
        $o->{$key} = $value;
    }
    return $o;
}

\b matches a word boundary. I think you can use ^$ for empty string.

From your code it would appear that you are trying to measure how long a computation took (as opposed to trying to figure out what the current time is).

In that case, you need to call currentTimeMillis before and after the computation, take the difference, and divide the result by 1000 to convert milliseconds to seconds.

Enhancement: replace timestamp with date

As a small enhancement to the accepted answer that was subsequently refined by ahoffner - it is possible to use a date format rather than timestamp. The advantages are:

1. readable dates in the database
2. no issue with the years > 2038 and timestamp
3. removes need to be careful with timestamps that are based on seasonally adjusted dates i.e. in the UK 28th June starts one hour earlier than 28th December so deriving a timestamp from a date can break the recursion algorithm.

to do this, change the DB repeat_start to be stored as type 'date' and repeat_interval now hold days rather than seconds. i.e. 7 for a repeat of 7 days.

change the sql line:

WHERE (( 1370563200 - repeat_start) % repeat_interval = 0 )

to:

WHERE ( DATEDIFF( '2013-6-7', repeat_start ) % repeat_interval = 0)

everything else remains the same. Simples!

In the case you need to manually 'exit' a transaction through code (be it through an exception or simply checking an error state) you shouldn't use DB::transaction() but instead wrap your code in DB::beginTransaction and DB::commit/DB::rollback():

DB::beginTransaction();

try {
    DB::insert(...);
    DB::insert(...);
    DB::insert(...);

    DB::commit();
    // all good
} catch (\Exception $e) {
    DB::rollback();
    // something went wrong
}

See the transaction docs.

try this

Object.keys(data).length

If IE < 9, you can loop through the object yourself with a for loop

var len = 0;
var i;

for (i in data) {
    if (data.hasOwnProperty(i)) {
        len++;
    }
}

Check out this question / answer. It's more concise than @Geoff's, and also uses the builtin fputcsv function.

$result = $db_con->query('SELECT * FROM `some_table`');
if (!$result) die('Couldn\'t fetch records');
$num_fields = mysql_num_fields($result);
$headers = array();
for ($i = 0; $i < $num_fields; $i++) {
    $headers[] = mysql_field_name($result , $i);
}
$fp = fopen('php://output', 'w');
if ($fp && $result) {
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename="export.csv"');
    header('Pragma: no-cache');
    header('Expires: 0');
    fputcsv($fp, $headers);
    while ($row = $result->fetch_array(MYSQLI_NUM)) {
        fputcsv($fp, array_values($row));
    }
    die;
}

I found that on Mavericks 10.8 there wasn't a .bash_profile and my paths were located in /etc/paths

In order to have the new path (whether this is a mamp or brew install of php) take effect it needs to be above the default /usr/bin/php in this paths file. eg.

/Applications/MAMP/bin/php/php5.3.6/bin
/usr/bin 

AFter the change, open a new terminal window and run 'which php' that should now point to your updated path

I did not found any solution here that show how to pass method with parameters bound to it as a parameter of a method. Bellow is example of how you can pass a method with parameter values already bound to it.

1. Step 1: Create two interfaces one with return type, another without. Java has similar interfaces but they are of little practical use because they do not support Exception throwing.

    public interface Do {
    void run() throws Exception;
    }


    public interface Return {
        R run() throws Exception;
    }

2. Example of how we use both interfaces to wrap method call in transaction. Note that we pass method with actual parameters.

    //example - when passed method does not return any value
    public void tx(final Do func) throws Exception {
        connectionScope.beginTransaction();
        try {
            func.run();
            connectionScope.commit();
        } catch (Exception e) {
            connectionScope.rollback();
            throw e;
        } finally {
            connectionScope.close();
        }
    }

    //Invoke code above by 
    tx(() -> api.delete(6));

Another example shows how to pass a method that actually returns something

        public  R tx(final Return func) throws Exception {
    R r=null;
    connectionScope.beginTransaction();
    try {
                r=func.run();
                connectionScope.commit();
            } catch (Exception e) {
                connectionScope.rollback();
                throw e;
            } finally {
                connectionScope.close();
            }
        return r;
        }
        //Invoke code above by 
        Object x= tx(() -> api.get(id));

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

Here's a simple explanation. You need to transfer 100 bucks from account A to account B. You can either do:

accountA -= 100;
accountB += 100;

or

accountB += 100;
accountA -= 100;

If something goes wrong between the first and the second operation in the pair you have a problem - either 100 bucks have disappeared, or they have appeared out of nowhere.

A transaction is a mechanism that allows you to mark a group of operations and execute them in such a way that either they all execute (commit), or the system state will be as if they have not started to execute at all (rollback).

beginTransaction;
accountB += 100;
accountA -= 100;
commitTransaction;

will either transfer 100 bucks or leave both accounts in the initial state.

From what I know

3 one-liners

1. a = 10 if <condition>

example:

a = 10 if true # a = 10
b = 10 if false # b = nil

2. a = 10 unless <condition>

example:

a = 10 unless false # a = 10
b = 10 unless true # b = nil

3. a = <condition> ? <a> : <b>

example:

a = true ? 10 : 100 # a = 10
a = false ? 10 : 100 # a = 100

I hope it helps.

SUMIF didn't worked for me, had to use SUMIFS.

=SUMIFS(TableAmount,TableMonth,"January")

TableAmount is the table to sum the values, TableMonth the table where we search the condition and January, of course, the condition to meet.

Hope this can help someone!

Try this line:

List<string> stringList = line.Split(',').ToList(); 

An alternative in Java 8:

String[] strings = list.stream().toArray(String[]::new);

HI you can try this...

Try..

$Ad = Get-ADUser -SearchBase "OU=OUi,DC=company,DC=com"  -Filter * -Properties employeeNumber | ? {$_.employeenumber -eq ""}
$Ad | Sort-Object -Property sn, givenName | Select * | Export-Csv c:\scripts\ceridian\NoClockNumber_2013_02_12.csv -NoTypeInformation

Or

$Ad = Get-ADUser -SearchBase "OU=OUi,DC=company,DC=com"  -Filter * -Properties employeeNumber | ? {$_.employeenumber -eq $null}
$Ad | Sort-Object -Property sn, givenName | Select * | Export-Csv c:\scripts\cer

Hope it works for you.
