First, it usually does not matter that much in practice. Most hash functions are "good enough".

But if you really care, you should know that it is a research subject by itself. There are thousand of papers about that. You can still get a PhD today by studying & designing hashing algorithms.

Your second hash function might be slightly better, because it probably should separate the string "ab" from the string "ba". On the other hand, it is probably less quick than the first hash function. It may, or may not, be relevant for your application.

I'll guess that hash functions used for genome strings are quite different than those used to hash family names in telephone databases. Perhaps even some string hash functions are better suited for German, than for English or French words.

Many software libraries give you good enough hash functions, e.g. Qt has qhash, and C++11 has std::hash in <functional>, Glib has several hash functions in C, and POCO has some hash function.

I quite often have hashing functions involving primes (see Bézout's identity) and xor, like e.g.

#define A 54059 /* a prime */
#define B 76963 /* another prime */
#define C 86969 /* yet another prime */
#define FIRSTH 37 /* also prime */
unsigned hash_str(const char* s)
{
   unsigned h = FIRSTH;
   while (*s) {
     h = (h * A) ^ (s[0] * B);
     s++;
   }
   return h; // or return h % C;
}

But I don't claim to be an hash expert. Of course, the values of A, B, C, FIRSTH should preferably be primes, but you could have chosen other prime numbers.

Look at some MD5 implementation to get a feeling of what hash functions can be.

Most good books on algorithmics have at least a whole chapter dedicated to hashing. Start with wikipages on hash function & hash table.

Got the error (in the function init) with the following code ;

"use strict" ;

var hdr ;

function init(){ // called on load
    hdr = document.getElementById("hdr");
}

... while using the stock browser on a Samsung galaxy Fame ( crap phone which makes it a good tester ) - userAgent ; Mozilla/5.0 (Linux; U; Android 4.1.2; en-gb; GT-S6810P Build/JZO54K) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30

The same code works everywhere else I tried including the stock browser on an older HTC phone - userAgent ; Mozilla/5.0 (Linux; U; Android 2.3.5; en-gb; HTC_WildfireS_A510e Build/GRJ90) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

The fix for this was to change

var hdr ;

to

var hdr = null ;

Try this:

<div id="wrapper">
    <div class="float left">left</div>
    <div class="float right">right</div>
</div>

#wrapper {
   width:500px; 
   height:300px; 
   position:relative;
}

.float {
   background-color:black; 
   height:300px; 
   margin:0; 
   padding:0; 
   color:white;
}

.left {

}

.right {

Due to https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html#option_mysqldump_lock-tables :

Some options, such as --opt (which is enabled by default), automatically enable --lock-tables. If you want to override this, use --skip-lock-tables at the end of the option list.

If you work with UIScrollView and UIPageControl, this method will also change the PageControl's page view.

  func scrollViewWillEndDragging(scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {

    let targetOffset = targetContentOffset.memory.x
    let widthPerPage = scrollView.contentSize.width / CGFloat(pageControl.numberOfPages)

    let currentPage = targetOffset / widthPerPage
    pageControl.currentPage = Int(currentPage)
}

Thanks @Esq 's Swift code.

Although there is clearly some kind of network instability or something interfering with your connection (15 minutes is possible that you could be crossing a NAT boundary or something in your network is dropping the session), I would think you want such a simple?) query to return well within any anticipated timeoue (like 1s).

I would talk to your DBA and get an index created on the underlying tables on MemberType, Status. If there isn't a single underlying table or these are more complex and created by the view or UDF, and you are running SQL Server 2005 or above, have him consider indexing the view (basically materializing the view in an indexed fashion).

Have you tried the following:

SELECT ID, COUNT(*), max(date)
FROM table 
GROUP BY ID;

The SQL you need is:

Update table set table_column = "test";

The SQL you posted creates a new row rather than updating existing rows.

You could also use tools provided by the base JRE:

String msg = "<message>HELLO!</message>";
DocumentBuilder newDocumentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document parse = newDocumentBuilder.parse(new ByteArrayInputStream(msg.getBytes()));
System.out.println(parse.getFirstChild().getTextContent());

As pointed out by Martijn, glob can only do this through the **operator introduced in Python 3.5. Since the OP explicitly asked for the glob module, the following will return a lazy evaluation iterator that behaves similarly

import os, glob, itertools

configfiles = itertools.chain.from_iterable(glob.iglob(os.path.join(root,'*.txt'))
                         for root, dirs, files in os.walk('C:/Users/sam/Desktop/file1/'))

Note that you can only iterate once over configfiles in this approach though. If you require a real list of configfiles that can be used in multiple operations you would have to create this explicitly by using list(configfiles).

There's yet another way to do it using Shared Connections, ie: somebody initiates the connection, using a password, and every subsequent connection will multiplex over the same channel, negating the need for re-authentication. ( And its faster too )

# ~/.ssh/config 
ControlMaster auto
ControlPath ~/.ssh/pool/%r@%h

then you just have to log in, and as long as you are logged in, the bash script will be able to open ssh connections.

You can then stop your script from working when somebody has not already opened the channel by:

ssh ... -o KbdInteractiveAuthentication=no ....

Fixing pip

For this error:

~/Library/Python/2.7/bin/pip: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory`

The source of this problem is a bad python path hardcoded in pip (which means it won't be fixed by e.g. changing your $PATH). That path is no longer hardcoded in the lastest version of pip, so a solution which should work is:

pip install --upgrade pip

But of course, this command uses pip, so it fails with the same error.

The way to bootstrap yourself out of this mess:

1. Run which pip
2. Open that file in a text editor
3. Change the first line from #!/usr/local/opt/python/bin/python2.7 to e.g. #!/usr/local/opt/python2/bin/python2.7 (note the python2 in the path), or any path to a working python interpreter on your machine.
4. Now, pip install --upgrade pip (this overwrites your hack and gets pip working at the latest version, where the interpreter issue should be fixed)

Fixing virtualenv

For me, I found this issue by first having the identical issue from virtualenv:

~/Library/Python/2.7/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory`

The solution here is to run

pip uninstall virtualenv
pip install virtualenv

If running that command gives the same error from pip, see above.

npm install -g increase-memory-limit

increase-memory-limit

OR

1. Navigate to %appdata% -> npm folder or C:\Users\{user_name}\AppData\Roaming\npm
2. Open ng.cmd in your favorite editor
3. Add --max_old_space_size=8192 to the IF and ELSE block

now ng.cmd file looks like this after the change:

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" "--max_old_space_size=8192" "%~dp0\node_modules\@angular\cli\bin\ng" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node "--max_old_space_size=8192" "%~dp0\node_modules\@angular\cli\bin\ng" %*
)

I prefere this one:

private ResourceLoader resourceLoader = new DefaultResourceLoader();

@ResponseBody
@RequestMapping(value = "/{id}",  produces = "image/bmp")
public Resource texture(@PathVariable("id") String id) {
    return resourceLoader.getResource("classpath:images/" + id + ".bmp");
}

Change the media type to what ever image format you have.

Just so you know...

Adding to the litany of woes with these classes, there is a rather interesting bug that's worth sharing.

I'm using a ViewPager to navigate a tree of items (select an item and the view pager animates scrolling to the right, and the next branch appears, navigate back, and the ViewPager scrolls in the opposite direction to return to the previous node).

The problem arises when I push and pop fragments off the end of the FragmentStatePagerAdapter. It's smart enough to notice that the items change, and smart enough to create and replace a fragment when the item has changed. But not smart enough to discard the fragment state, or smart enough to trim the internally saved fragment states when the adapter size changes. So when you pop an item, and push a new one onto the end, the fragment for the new item gets the saved state of the fragment for the old item, which caused absolute havoc in my code. My fragments carry data that may require a lot of work to refetch from the internet, so not saving state really wasn't an option.

I don't have a clean workaround. I used something like this:

  public void onSaveInstanceState(Bundle outState) {
    IFragmentListener listener = (IFragmentListener)getActivity();
    if (listener!= null)
    {
        if (!listener.isStillInTheAdapter(this.getAdapterItem()))
        {
            return; // return empty state.
        }

    }
    super.onSaveInstanceState(outState);

    // normal saving of state for flips and 
    // paging out of the activity follows
    ....
  }

An imperfect solution because the new fragment instance still gets a savedState Bundle, but at least it doesn't carry stale data.

I just installed oracle11g

ORA-65096: invalid common user or role name in oracle

No, you have installed Oracle 12c. That error could only be on 12c, and cannot be on 11g.

Always check your database version up to 4 decimal places:

SELECT banner FROM v$version WHERE ROWNUM = 1;

Oracle 12c multitenant container database has:

• a root container(CDB)
• and/or zero, one or many pluggable databases(PDB).

You must have created the database as a container database. While, you are trying to create user in the container, i.e. CDB$ROOT, however, you should create the user in the PLUGGABLE database.

You are not supposed to create application-related objects in the container, the container holds the metadata for the pluggable databases. You should use the pluggable database for you general database operations. Else, do not create it as container, and not use multi-tenancy. However, 12cR2 onward you cannot create a non-container database anyway.

And most probably, the sample schemas might have been already installed, you just need to unlock them in the pluggable database.

For example, if you created pluggable database as pdborcl:

sqlplus SYS/password@PDBORCL AS SYSDBA

SQL> ALTER USER scott ACCOUNT UNLOCK IDENTIFIED BY tiger;

sqlplus scott/tiger@pdborcl

SQL> show user;
USER is "SCOTT"

To show the PDBs and connect to a pluggable database from root container:

SQL> show con_name

CON_NAME
------------------------------
CDB$ROOT

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 ORCLPDB                        READ WRITE NO

SQL> alter session set container = ORCLPDB;

Session altered.

SQL> show con_name;

CON_NAME
------------------------------
ORCLPDB

try chmod a+x /path/to/tomcat/bin/catalina.sh if you run it in intelliJ

I found this to occur when you mix ggplot charts with plot charts in the same session. Using the 'dev.off' solution suggested by Paul solves the issue.

I figured out the issue. The linked server was created correctly. However, after the server was upgraded and switched the server name in sys.servers still had the old server name.

I had to drop the old server name and add the new server name to sys.servers on the new server

sp_dropserver 'Server_A'
GO
sp_addserver  'Server',local
GO

I was fighting this issue recently and found a much better answer available in Spring 3.1:

@RequestMapping(value = "ajax/gethelp", produces = "text/plain")

So, as easy as JAX-RS just like all the comments indicated it could/should be.

Make sure your id_rsa file doesn't have any extension like .txt or .rtf. Rich Text Format adds additional characters to your file and those gets added to byte array. Which eventually causes invalid private key error. Long story short, Copy the file, not content.

If you are grouping by some other value, then instead of what you have,

write it as

Sum(CASE WHEN col1 > col2 THEN SUM(col3*col4) ELSE 0 END) as SumSomeProduct

If, otoh, you want to group By the internal expression, (col3*col4) then

write the group By to match the expression w/o the SUM...

Select Sum(Case When col1 > col2 Then col3*col4 Else 0 End) as SumSomeProduct
From ...

Group By Case When col1 > col2 Then col3*col4 Else 0 End 

Finally, if you want to group By the actual aggregate

Select SumSomeProduct, Count(*), <other aggregate functions>
From (Select <other columns you are grouping By>, 
      Sum(Case When col1 > col2 
          Then col3*col4 Else 0 End) as SumSomeProduct
      From Table
      Group By <Other Columns> ) As Z
Group by SumSomeProduct

You can create a batch by PreparedStatement#addBatch() and execute it by PreparedStatement#executeBatch().

Here's a kickoff example:

public void save(List<Entity> entities) throws SQLException {
    try (
        Connection connection = database.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL_INSERT);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setString(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

It's executed every 1000 items because some JDBC drivers and/or DBs may have a limitation on batch length.

Yes, take a look at this thread which talks about the differences between platforms.

How to detect right-click event for Mac OS

BUTTON3 is the same across all platforms, being equal to the right mouse button. BUTTON2 is simply ignored if the middle button does not exist.

My situation was solved by specifing the VM argument to the JAVA program being debugged, I assume you can also set this in `eclipse.ini file aswell:

hibernate3.HibernateQueryException: Books is not mapped [SELECT COUNT(*) FROM Books];

Hibernate is trying to say that it does not know an entity named "Books". Let's look at your entity:

@javax.persistence.Entity
@javax.persistence.Table(name = "Books")
public class Book {

Right. The table name for Book has been renamed to "Books" but the entity name is still "Book" from the class name. If you want to set the entity name, you should use the @Entity annotation's name instead:

// this allows you to use the entity Books in HQL queries
@javax.persistence.Entity(name = "Books")
public class Book {

That sets both the entity name and the table name.

The opposite problem happened to me when I was migrating from the Person.hbm.xml file to using the Java annotations to describe the hibernate fields. My old XML file had:

<hibernate-mapping package="...">
    <class name="Person" table="persons" lazy="true">
       ...
</hibernate-mapping>

And my new entity had a @Entity(name=...) which I needed to set the name of the table.

// this renames the entity and sets the table name
@javax.persistence.Entity(name = "persons")
public class Person {
    ...

What I then was seeing was HQL errors like:

QuerySyntaxException: Person is not mapped
     [SELECT id FROM Person WHERE id in (:ids)]

The problem with this was that the entity name was being renamed to persons as well. I should have set the table name using:

// no name = here so the entity can be used as Person
@javax.persistence.Entity
// table name specified here
@javax.persistence.Table(name = "persons")
public class Person extends BaseGeneratedId {

Hope this helps others.

I had the same problem. For me the solution is to delete the remote file and let rsync create again.

Open Terminal:

sudo gem update --system 

It works!

Old thread, I know. I needed also something to monitor events and wrote this very handy (excellent) solution. You can monitor all events with this hook (in windows programming this is called a hook). This hook does not affects the operation of your software/program.

In the console log you can see something like this:

Explanation of what you see:

In the console log you will see all events you select (see below "how to use") and shows the object-type, classname(s), id, <:name of function>, <:eventname>. The formatting of the objects is css-like.

When you click a button or whatever binded event, you will see it in the console log.

The code I wrote:

function setJQueryEventHandlersDebugHooks(bMonTrigger, bMonOn, bMonOff)
{
   jQuery.fn.___getHookName___ = function()    
       {
          // First, get object name
         var sName = new String( this[0].constructor ),
         i = sName.indexOf(' ');
         sName = sName.substr( i, sName.indexOf('(')-i );    

         // Classname can be more than one, add class points to all
         if( typeof this[0].className === 'string' )
         {
           var sClasses = this[0].className.split(' ');
           sClasses[0]='.'+sClasses[0];
           sClasses = sClasses.join('.');
           sName+=sClasses;
         }
         // Get id if there is one
         sName+=(this[0].id)?('#'+this[0].id):'';
         return sName;
       };

   var bTrigger        = (typeof bMonTrigger !== "undefined")?bMonTrigger:true,
       bOn             = (typeof bMonOn !== "undefined")?bMonOn:true,
       bOff            = (typeof bMonOff !== "undefined")?bMonOff:true,
       fTriggerInherited = jQuery.fn.trigger,
       fOnInherited    = jQuery.fn.on,
       fOffInherited   = jQuery.fn.off;

   if( bTrigger )
   {
    jQuery.fn.trigger = function()
    {
     console.log( this.___getHookName___()+':trigger('+arguments[0]+')' );
     return fTriggerInherited.apply(this,arguments);
    };
   }

   if( bOn )
   {
    jQuery.fn.on = function()
    {
     if( !this[0].__hooked__ ) 
     {
       this[0].__hooked__ = true; // avoids infinite loop!
       console.log( this.___getHookName___()+':on('+arguments[0]+') - binded' );
       $(this).on( arguments[0], function(e)
       {
         console.log( $(this).___getHookName___()+':'+e.type );
       });
     }
     var uResult = fOnInherited.apply(this,arguments);
     this[0].__hooked__ = false; // reset for another event
     return uResult;
    };
   }

   if( bOff )
   {
    jQuery.fn.off = function()
    {
     if( !this[0].__unhooked__ ) 
     {
       this[0].__unhooked__ = true; // avoids infinite loop!
       console.log( this.___getHookName___()+':off('+arguments[0]+') - unbinded' );
       $(this).off( arguments[0] );
     }

     var uResult = fOffInherited.apply(this,arguments);
     this[0].__unhooked__ = false; // reset for another event
     return uResult;
    };
   }
}

Examples how to use it:

Monitor all events:

setJQueryEventHandlersDebugHooks();

Monitor all triggers only:

setJQueryEventHandlersDebugHooks(true,false,false);

Monitor all ON events only:

setJQueryEventHandlersDebugHooks(false,true,false);

Monitor all OFF unbinds only:

setJQueryEventHandlersDebugHooks(false,false,true);

Remarks/Notice:

• Use this for debugging only, turn it off when using in product final version
• If you want to see all events, you have to call this function directly after jQuery is loaded
• If you want to see only less events, you can call the function on the time you need it
• If you want to auto execute it, place ( )(); around function

Hope it helps! ;-)

I wasn't satisfied with the accepted answer so I created some scripts to do this for you available on Github. These should help anyone who wants to use git svn clone but doesn't want to clone the entire repository and doesn't want to hunt for a specific revision to clone from in the middle of the history (maybe you're cloning a bunch of repos). Here we can just clone the last N revisions:

Use git svn clone to clone the last 50 revisions

# -u    The SVN URL to clone
# -l    The limit of revisions
# -o    The output directory

./git-svn-cloneback.sh -u https://server/project/trunk -l 50 -o myproj --authors-file=svn-authors.txt

Find the previous N revision from an SVN repo

Draw 2 texts: one gray (it will be the shadow) and on top of it draw the second text (y coordinate 1px more then shadow text).

To add to add to the previous answer, there is even a fourth way that can be used

import codecs
encoded4 = codecs.encode(original, 'utf-8')
print(encoded4)

Although other solutions are useful for a single function, I recommend the following piece of code where is more general and effective:

Rprof(tf <- "log.log", memory.profiling = TRUE)
# the code you want to profile must be in between
Rprof (NULL) ; print(summaryRprof(tf))

I found another reason for this type of error: in my case, someone set the conf/catalina.properties setting tomcat.util.scan.StandardJarScanFilter.jarsToSkip property to * to avoid log warning messages, thereby skipping the necessary scan by Tomcat. Changing this back to the Tomcat default and adding an appropriate list of jars to skip (not including jstl-1.2 or spring-webmvc) solved the problem.

HTML is in its basic form just XML. You could Parse your text in an XmlDocument object, and on the root element call InnerText to extract the text. This will strip all HTML tages in any form and also deal with special characters like &lt; &nbsp; all in one go.

The size attribute works, as well

<input size="25" type="text">

my_module is a folder not a module and you can't import a folder, try moving my_mod.py to the same folder as the cool_script.py and then doimport my_mod as mm. This is because python only looks in the current directory and sys.path, and so wont find my_mod.py unless it's in the same directory

Or you can look here for an answer telling you how to import from other directories.

As to your other questions, I do not know as I do not use PyCharm.

I'm a newbie in Ansible, but I would suggest next solution:

playbook.yml

...
vars:
  command_output_full:
    stdout: will be overriden below
  command_output: {{ command_output_full.stdout }}
...
...
...
tasks:
  - name: Create variable from command
    command: "echo Hello"
    register: command_output_full
  - debug: msg="{{ command_output }}"

It should work (and works for me) because Ansible uses lazy evaluation. But it seems it checks validity before the launch, so I have to define command_output_full.stdout in vars.

And, of course, if it is too many such vars in vars section, it will look ugly.

In the server, do something like this:

Suppose

String data = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAPAAAADwCAYAAAA+VemSAAAgAEl...=='

Then:

String base64Image = data.split(",")[1];
byte[] imageBytes = javax.xml.bind.DatatypeConverter.parseBase64Binary(base64Image);

Then you can do whatever you like with the bytes like:

BufferedImage img = ImageIO.read(new ByteArrayInputStream(imageBytes));

You'll need to create an Action on your Controller that returns the rendered result of the "UserDetails" partial view or control. Then just use an Http Get or Post from jQuery to call the Action to get the rendered html to be displayed.

In some cases, you may run into a problem of synchronization with this method. I wrote the callback call inside a setTimeout function, and it worked synchronously just fine =)

E.G:

function obterJson(callback) {


    jqxhr = $.getJSON(window.location.href + "js/data.json", function(data) {

    setTimeout(function(){
        callback(data);
    },0);
}

I realize this is an old question, but it took me several hours to find a good solution and thought I'd pass on what I learned here and save someone else the trouble. Try, for example,

SELECT * FROM some_table WHERE id_column = ANY(@id_list)

where @id_list is bound to an int[] parameter by way of

command.Parameters.Add("@id_list", NpgsqlDbType.Array | NpgsqlDbType.Integer).Value = my_id_list;

where command is a NpgsqlCommand (using C# and Npgsql in Visual Studio).

One can also checkout all files from the other branch into master:

git checkout master
git checkout better_branch -- .

and then commit all changes.

When you are selecting INTO a variable and there are no records returned you should get a NO DATA FOUND error. I believe the correct way to write the above code would be to wrap the SELECT statement with it's own BEGIN/EXCEPTION/END block. Example:

...
v_final_grade NUMBER;
v_letter_grade CHAR(1);
BEGIN

    BEGIN
    SELECT final_grade
      INTO v_final_grade
      FROM enrollment
     WHERE student_id = v_student_id
       AND section_id = v_section_id;

    EXCEPTION
      WHEN NO_DATA_FOUND THEN
        v_final_grade := NULL;
    END;

    CASE -- outer CASE
      WHEN v_final_grade IS NULL THEN
      ...

Hows about this:

$json=Get-Content -Raw -Path 'my.json' | Out-String | ConvertFrom-Json
$foo="TheVariableYourUsingToSelectSomething"
$json.SomePathYouKnow.psobject.properties.Where({$_.name -eq $foo}).value

which would select from json structured

{"SomePathYouKnow":{"TheVariableYourUsingToSelectSomething": "Tada!"}

This is based on this accessing values in powershell SO question . Isn't powershell fabulous!

I want to know the time to brute force for when the password is a dictionary word and also when it is not a dictionary word.

Dictionary password

Ballpark figure: there are about 1,000,000 English words, and if a hacker can compute about 10,000 SHA-512 hashes a second (update: see comment by CodesInChaos, this estimate is very low), 1,000,000 / 10,000 = 100 seconds. So it would take just over a minute to crack a single-word dictionary password for a single user. If the user concatenates two dictionary words, you're in the area of a few days, but still very possible if the attacker is cares enough. More than that and it starts getting tough.

Random password

If the password is a truly random sequence of alpha-numeric characters, upper and lower case, then the number of possible passwords of length N is 60^N (there are 60 possible characters). We'll do the calculation the other direction this time; we'll ask: What length of password could we crack given a specific length of time? Just use this formula:

N = Log60(t * 10,000) where t is the time spent calculating hashes in seconds (again assuming 10,000 hashes a second).

1 minute:    3.2
5 minute:    3.6
30 minutes:  4.1
2 hours:     4.4
3 days:      5.2

So given a 3 days we'd be able to crack the password if it's 5 characters long.

This is all very ball-park, but you get the idea. Update: see comment below, it's actually possible to crack much longer passwords than this.

What's going on here?

Let's clear up some misconceptions:

• The salt doesn't make it slower to calculate hashes, it just means they have to crack each user's password individually, and pre-computed hash tables (buzz-word: rainbow tables) are made completely useless. If you don't have a precomputed hash-table, and you're only cracking one password hash, salting doesn't make any difference.

• SHA-512 isn't designed to be hard to brute-force. Better hashing algorithms like BCrypt, PBKDF2 or SCrypt can be configured to take much longer to compute, and an average computer might only be able to compute 10-20 hashes a second. Read This excellent answer about password hashing if you haven't already.

• update: As written in the comment by CodesInChaos, even high entropy passwords (around 10 characters) could be bruteforced if using the right hardware to calculate SHA-512 hashes.

Notes on accepted answer:

The accepted answer as of September 2014 is incorrect and dangerously wrong:

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack)... Finding a collision using a birthday attack takes O(2^n/2) time, where n is the output length of the hash function in bits.

The birthday attack is completely irrelevant to cracking a given hash. And this is in fact a perfect example of a preimage attack. That formula and the next couple of paragraphs result in dangerously high and completely meaningless values for an attack time. As demonstrated above it's perfectly possible to crack salted dictionary passwords in minutes.

The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords...

That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5...

Yes, please use an algorithm that is slow to compute, but what is "entropy-enducing"? Putting a low entropy password through a hash doesn't increase entropy. It should preserve entropy, but you can't make a rubbish password better with a hash, it doesn't work like that. A weak password put through PBKDF2 is still a weak password.

I like Seaborn's regplot or lmplot for this:

Java supports closures just fine. It just doesn't support functions, so the syntax you're used to for closures is much more awkward and bulky: you have to wrap everything up in a class with a method. For example,

public Runnable foo(final int x) {
  return new Runnable() {
    public void run() {
      System.out.println(x);
    }
  };
}

Will return a Runnable object whose run() method "closes over" the x passed in, just like in any language that supports first-class functions and closures.

You want:

DECLARE @times int

SELECT @times =  COUNT(DidWin)
FROM thetable
WHERE DidWin = 1 AND Playername='Me'

You also don't need the 'as' clause.

import UIKit

class TabbarViewController: UITabBarController,UITabBarControllerDelegate {

//MARK:- View Life Cycle

override func viewDidLoad() {
    super.viewDidLoad()

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()

}

//Tabbar delegate method
override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
    let yourView = self.viewControllers![self.selectedIndex] as! UINavigationController
    yourView.popToRootViewController(animated:false)
}



}

You can simplify things quite a bit by creating a class that derives from WebClient, overriding its GetWebRequest method and setting a CookieContainer object on it. If you always set the same CookieContainer instance, then cookie management will be handled automatically for you.

But the only way to get at the HttpWebRequest before it is sent is to inherit from WebClient and override that method.

public class CookieAwareWebClient : WebClient
{
    private CookieContainer cookie = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest request = base.GetWebRequest(address);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).CookieContainer = cookie;
        }
        return request;
    }
}

var client = new CookieAwareWebClient();
client.BaseAddress = @"https://www.site.com/any/base/url/";
var loginData = new NameValueCollection();
loginData.Add("login", "YourLogin");
loginData.Add("password", "YourPassword");
client.UploadValues("login.php", "POST", loginData);

//Now you are logged in and can request pages    
string htmlSource = client.DownloadString("index.php");

System.Text.ASCIIEncoding.Unicode.GetByteCount(yourString);

Or

System.Text.ASCIIEncoding.ASCII.GetByteCount(yourString);

You could also just change the @RequestParam default required status to false so that HTTP response status code 400 is not generated. This will allow you to place the Annotations in any order you feel like.

@RequestParam(required = false)String name

While it is true that exporting an excel file that contains special characters to csv can be a pain in the ass, there is however a simple work around: simply copy/paste the cells into a google docs and then save from there.

We all know that programming have endless possibilities.There are numbers of solutions available for a single problem so i think all of the above solutions are perfect and may be helpful for someone but for me this one save my day..

So Code goes like this

  private void getWebsite() {
    new Thread(new Runnable() {
      @Override
      public void run() {
        final StringBuilder builder = new StringBuilder();

        try {
          Document doc = Jsoup.connect("http://www.ssaurel.com/blog").get();
          String title = doc.title();
          Elements links = doc.select("a[href]");

          builder.append(title).append("\n");

          for (Element link : links) {
            builder.append("\n").append("Link : ").append(link.attr("href"))
            .append("\n").append("Text : ").append(link.text());
          }
        } catch (IOException e) {
          builder.append("Error : ").append(e.getMessage()).append("\n");
        }

        runOnUiThread(new Runnable() {
          @Override
          public void run() {
            result.setText(builder.toString());
          }
        });
      }
    }).start();
  }

You just have to call the above function in onCreate Method of your MainActivity

I hope this one is also helpful for you guys.

Also read the original blog at Medium

i am using v3.1.3 and i had to use data('DateTimePicker') like this

var fromE = $( "#" + fromInput );
var toE = $( "#" + toInput );
$('.form-datepicker').datetimepicker(dtOpts);

$('.form-datepicker').on('change', function(e){
   var isTo = $(this).attr('name') === 'to';

   $( "#" + ( isTo ? fromInput : toInput  ) )
      .data('DateTimePicker')[ isTo ? 'setMaxDate' : 'setMinDate' ](moment($(this).val(), 'DD/MM/YYYY'))
});

you can easily wrap a button with a link like so <a href="#"> <button>my button </button> </a>

Since List<> uses arrays internally, the basic performance should be the same. Two reasons, why the List might be slightly slower:

• To look up a element in the list, a method of List is called, which does the look up in the underlying array. So you need an additional method call there. On the other hand the compiler might recognize this and optimize the "unnecessary" call away.
• The compiler might do some special optimizations if it knows the size of the array, that it can't do for a list of unknown length. This might bring some performance improvement if you only have a few elements in your list.

To check if it makes any difference for you, it's probably best adjust the posted timing functions to a list of the size you're planning to use and see how the results for your special case are.

If you are using Spring4/SpringBoot 1.x, then it's worth mentioning that you can add "text" (json) parts as well . This can be done via MockMvcRequestBuilders.fileUpload().file(MockMultipartFile file) (which is needed as method .multipart() is not available in this version):

@Test
public void test() throws Exception {

   mockMvc.perform( 
       MockMvcRequestBuilders.fileUpload("/files")
         // file-part
         .file(makeMultipartFile( "file-part" "some/path/to/file.bin", "application/octet-stream"))
        // text part
         .file(makeMultipartTextPart("json-part", "{ \"foo\" : \"bar\" }", "application/json"))
       .andExpect(status().isOk())));

   }

   private MockMultipartFile(String requestPartName, String filename, 
       String contentType, String pathOnClassPath) {

       return new MockMultipartFile(requestPartName, filename, 
          contentType, readResourceFile(pathOnClasspath);
   }

   // make text-part using MockMultipartFile
   private MockMultipartFile makeMultipartTextPart(String requestPartName, 
       String value, String contentType) throws Exception {

       return new MockMultipartFile(requestPartName, "", contentType,
               value.getBytes(Charset.forName("UTF-8")));   
   }


   private byte[] readResourceFile(String pathOnClassPath) throws Exception {
      return Files.readAllBytes(Paths.get(Thread.currentThread().getContextClassLoader()
         .getResource(pathOnClassPath).toUri()));
   }

}

Surely using your own panel or form would be by far the simplest approach if a little more heavy on the background (designer) code. It gives all the control in terms of centring and manipulation without writing all that custom code.

For my case I'm facing it on iOS, and I've tried to reset and clear all cache using below command but failed too, despite many comments saying that the root cause is there is react packager running somewhere accidentally, I've restarted my mac and the problem still remained.

watchman watch-del-all && rm -rf node_modules/ && yarn cache clean && yarn install && yarn start --reset-cache

The solution is, to delete the build folder @ /ios/build, then execute react-native run-ios solved it

In addition to the steps you have already taken, you will need to set the recovery mode to simple before you can shrink the log.

THIS IS NOT A RECOMMENDED PRACTICE for production systems... You will lose your ability to recover to a point in time from previous backups/log files.

See example B on this DBCC SHRINKFILE (Transact-SQL) msdn page for an example, and explanation.

But this is obviously performing a 'string' comparison

No. The string will be automatically cast into a DATETIME value.

See 11.2. Type Conversion in Expression Evaluation.

When an operator is used with operands of different types, type conversion occurs to make the operands compatible. Some conversions occur implicitly. For example, MySQL automatically converts numbers to strings as necessary, and vice versa.

Here is my solution changing the Mysql configuration through the phpmyadmin dashboard:

In order to fix "this is incompatible with sql_mode=only_full_group_by": Open phpmyadmin and goto Home Page and select 'Variables' submenu. Scroll down to find sql mode. Edit sql mode and remove 'ONLY_FULL_GROUP_BY' Save it.

I used conda-forge to install pillow version 5, and that seemed to work for me:

conda install --channel conda-forge pillow=5

the normal conda install pillow did NOT work for me.

    first_list = [1, 2, 2, 5]
    second_list = [2, 5, 7, 9]

    newList=[]
    for i in first_list:
        newList.append(i)
    for z in second_list:
        if z not in newList:
            newList.append(z)
    newList.sort()
    print newList

[1, 2, 2, 5, 7, 9]

There's no easy way to do this, but something like this will work:

SELECT ET.TrainingID, 
  ET.CompletedDate, 
  ET.Notes
FROM 
HR_EmployeeTrainings ET
inner join
(
  select TrainingID, Max(CompletedDate) as CompletedDate
  FROM HR_EmployeeTrainings
  WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID)
  GROUP BY AvantiRecID, TrainingID  
) ET2 
  on ET.TrainingID = ET2.TrainingID
  and ET.CompletedDate = ET2.CompletedDate

At first glance, I figured divmod would be faster since it's a single statement and a built-in function, but timeit seems to show otherwise. Consider this little example I came up with when I was trying to figure out the fastest method for use in a loop that continuously runs in a gobject idle_add splitting a seconds counter into a human readable time for updating a progress bar label.

import timeit

def test1(x,y, dropy):
    while x > 0:
        y -= dropy
        x -= 1

        # the test
        minutes = (y-x) / 60
        seconds = (y-x) % 60.0

def test2(x,y, dropy):
    while x > 0:
        y -= dropy
        x -= 1

        # the test
        minutes, seconds = divmod((y-x), 60)

x = 55     # litte number, also number of tests
y = 10000  # make y > x by factor of drop
dropy = 7 # y is reduced this much each iteration, for variation

print "division and modulus:", timeit.timeit( lambda: test1(x,y,dropy) )
print "divmod function:",      timeit.timeit( lambda: test2(x,y,dropy) )

The built-in divmod function seems incredibly slower compared to using the simple division and modulus.

division and modulus: 12.5737669468
divmod function: 17.2861430645

If anyone wants to use purely Java configuration instead of xml configuration of hibernate, use this:

You can configure Hibernate without using persistence.xml at all in Spring like like this:

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean()
{
Map<String, Object> properties = new Hashtable<>();
properties.put("javax.persistence.schema-generation.database.action",
"none");
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect"); //you can change this if you have a different DB
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(adapter);
factory.setDataSource(this.springJpaDataSource());
factory.setPackagesToScan("package name");
factory.setSharedCacheMode(SharedCacheMode.ENABLE_SELECTIVE);
factory.setValidationMode(ValidationMode.NONE);
factory.setJpaPropertyMap(properties);
return factory;
}

Since you are not using persistence.xml, you should create a bean that returns DataSource which you specify in the above method that sets the data source:

@Bean
public DataSource springJpaDataSource()
{
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl("jdbc:mysql://localhost/SpringJpa");
dataSource.setUsername("tomcatUser");
dataSource.setPassword("password1234");
return dataSource;
}

Then you use @EnableTransactionManagement annotation over this configuration file. Now when you put that annotation, you have to create one last bean:

@Bean
public PlatformTransactionManager jpaTransactionManager()
{
return new JpaTransactionManager(
this.entityManagerFactoryBean().getObject());
}

Now, don't forget to use @Transactional Annotation over those method that deal with DB.

Lastly, don't forget to inject EntityManager in your repository (This repository class should have @Repository annotation over it).

select column_name, data_type, character_maximum_length    
from INFORMATION_SCHEMA.COLUMNS
where table_name = 'Table1'

Since AngularJS 1.5 we should use $onInit which is available on any AngularJS component. Taken from the component lifecycle documentation since v1.5 its the preffered way:

$onInit() - Called on each controller after all the controllers on an element have been constructed and had their bindings initialized (and before the pre & post linking functions for the directives on this element). This is a good place to put initialization code for your controller.

var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function ($scope) {

    //default state
    $scope.name = '';

    //all your init controller goodness in here
    this.$onInit = function () {
      $scope.name = 'Superhero';
    }
});

>> Fiddle Demo

An advanced example of using component lifecycle:

The component lifecycle gives us the ability to handle component stuff in a good way. It allows us to create events for e.g. "init", "change" or "destroy" of an component. In that way we are able to manage stuff which is depending on the lifecycle of an component. This little example shows to register & unregister an $rootScope event listener $on. By knowing, that an event $on binded on $rootScope will not be undinded when the controller loses its reference in the view or getting destroyed we need to destroy a $rootScope.$on listener manually. A good place to put that stuff is $onDestroy lifecycle function of an component:

var myApp = angular.module('myApp',[]);

myApp.controller('MyCtrl', function ($scope, $rootScope) {

  var registerScope = null;

  this.$onInit = function () {
    //register rootScope event
    registerScope = $rootScope.$on('someEvent', function(event) {
        console.log("fired");
    });
  }

  this.$onDestroy = function () {
    //unregister rootScope event by calling the return function
    registerScope();
  }
});

I think you can use MDC to change logging level programmatically. The code below is an example to change logging level on current thread. This approach does not create dependency to logback implementation (SLF4J API contains MDC).

<configuration>
  <turboFilter class="ch.qos.logback.classic.turbo.DynamicThresholdFilter">
    <Key>LOG_LEVEL</Key>
    <DefaultThreshold>DEBUG</DefaultThreshold>
    <MDCValueLevelPair>
      <value>TRACE</value>
      <level>TRACE</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>DEBUG</value>
      <level>DEBUG</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>INFO</value>
      <level>INFO</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>WARN</value>
      <level>WARN</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>ERROR</value>
      <level>ERROR</level>
    </MDCValueLevelPair>
  </turboFilter>
  ......
</configuration>

MDC.put("LOG_LEVEL", "INFO");

1. Parse the file into a python list using file.readlines() or file.read().split('\n')
2. Identify the position where you have to insert a new line, according to your criteria.
3. Insert a new list element there using list.insert().
4. Write the result to the file.

Yes, you would have to change the window.location.href to the url of the file you would want to download.

window.location.href = 'http://www.com/path/to/file';

The problem with other proposed solutions is that they will either drop characters that cannot be directly mapped to ASCII, or replace them with a marker character like ?.

You might desire to have for example accented characters converted to that same character without the accent. There are a couple of tricks to do this (including building a static mapping table yourself or leveraging existing 'normalization' defined for unicode), but those methods are far from complete.

Your best bet is using the junidecode library, which cannot be complete either but incorporates a lot of experience in the most sane way of transliterating Unicode to ASCII.

One cheeky solution :

  function printDiv(divID) {
        //Get the HTML of div
        var divElements = document.getElementById(divID).innerHTML;
        //Get the HTML of whole page
        var oldPage = document.body.innerHTML;
        //Reset the page's HTML with div's HTML only
        document.body.innerHTML = 
          "<html><head><title></title></head><body>" + 
          divElements + "</body>";
        //Print Page
        window.print();
        //Restore orignal HTML
        document.body.innerHTML = oldPage;

    }

HTML :

<form id="form1" runat="server">
    <div id="printablediv" style="width: 100%; background-color: Blue; height: 200px">
        Print me I am in 1st Div
    </div>
    <div id="donotprintdiv" style="width: 100%; background-color: Gray; height: 200px">
        I am not going to print
    </div>
    <input type="button" value="Print 1st Div" onclick="javascript:printDiv('printablediv')" />
</form>

Integer is only there for the sql standard ie deprecated by Oracle.

You should use Number instead.

Integers get stored as Number anyway by Oracle behind the scenes.

Most commonly when ints are stored for IDs and such they are defined with no params - so in theory you could look at the scale and precision columns of the metadata views to see of no decimal values can be stored - however 99% of the time this will not help.

As was commented above you could look for number(38,0) columns or similar (ie columns with no decimal points allowed) but this will only tell you which columns cannot take decimals, and not what columns were defined so that INTS can be stored.

Suggestion: do a data profile on the number columns. Something like this:

 select max( case when trunc(column_name,0)=column_name then 0 else 1 end ) as has_dec_vals
 from table_name

Answer to your question is NO.

Correct is MyString[position of character]. For your case MyString[0], 0 is the FIRST character of any string.

A character value is designated with ' (single quote), like this x character value is written as 'x'.

A string value is designated with " ( double quote), like this x string value is written as "x".

So Substring() method is also does not return a character, Substring() method returns a string!!!

A string is an array of characters, and last character must be '\0' (null) character. Thats the difference between character array and string ( which is an array of characters with last character as "end of string marker" '\0' null.

And also notice that 'x' IS NOT EQUAL to "x". Because "x" is actually 'x'+'\0'.

In this simple example you can just put synchronized as a modifier after public in both method signatures.

More complex scenarios require other stuff.

According to the React Documentation it's perfectly OK to call setState() from within the componentDidMount() function.

It will cause render() to be called twice, which is less efficient than only calling it once, but other than that it's perfectly fine.

You can find the documentation here:

https://reactjs.org/docs/react-component.html#componentdidmount

Here is the excerpt from the documentation:

You may call setState() immediately in componentDidMount(). It will trigger an extra rendering, but it will happen before the browser updates the screen. This guarantees that even though the render() will be called twice in this case, the user won’t see the intermediate state. Use this pattern with caution because it often causes performance issues...

You can put your test specific properties into src/test/resources/config/application.properties.

The properties defined in this file will override those defined in src/main/resources/application.properties during testing.

For more information on why this works have a look at Spring Boots docs.

You cannot trust g++ 4.6.3 here with 64 bit integers on a 32 bit intel platform. a/b is computed by a call to divdi3 and a%b is computed by a call to moddi3. I can even come up with an example that computes a/b and a-b*(a/b) with these calls. So I use c=a/b and a-b*c.

The div method gives a call to a function which computes the div structure, but a function call seems inefficient on platforms which have hardware support for the integral type (i.e. 64 bit integers on 64 bit intel/amd platforms).

You can use GNU date, for example,

$ sec=1267619929
$ date -d "UTC 1970-01-01 $sec secs"

or

$ date -ud @1267619929

See doco for setText() in TextView http://developer.android.com/reference/android/widget/TextView.html

To style your strings, attach android.text.style.* objects to a SpannableString, or see the Available Resource Types documentation for an example of setting formatted text in the XML resource file.

You can use "strings" to extract strings from a binary file, for example

strings binary.file | grep foo

Try

$sqlupdate1 = "UPDATE table SET commodity_quantity=$qty WHERE user={$rows['user']} ";

You need curly brackets for array access in double quoted strings.

No you can't they are different. When the app was deployed your controller mappings would be borked for example.

Why do you want to anyway, a controller is not a service, and vice versa.

Can you post the signature of your method that is supposed to accept this post?

Additionally I get the same error message, possibly for a different reason. My YSOD talked about the dictionary not containing a value for the non-nullable value. The way I got the YSOD information was to put a breakpoint in the $.ajax function that handled an error return as follows:

<script type="text/javascript" language="javascript">
function SubmitAjax(url, message, successFunc, errorFunc) {
    $.ajax({
        type:'POST',
        url:url,
        data:message,
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        success:successFunc,
        error:errorFunc
        });

};

Then my errorFunc javascript is like this:

function(request, textStatus, errorThrown) {
        $("#install").text("Error doing auto-installer search, proceed with ticket submission\n"
        +request.statusText); }

Using IE I went to view menu -> script debugger -> break at next statement. Then went to trigger the code that would launch my post. This usually took me somewhere deep inside jQuery's library instead of where I wanted, because the select drop down opening triggered jQuery. So I hit StepOver, then the actual next line also would break, which was where I wanted to be. Then VS goes into client side(dynamic) mode for that page, and I put in a break on the $("#install") line so I could see (using mouse over debugging) what was in request, textStatus, errorThrown. request. In request.ResponseText there was an html message where I saw:

<title>The parameters dictionary contains a null entry for parameter 'appId' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ContentResult CheckForInstaller(Int32)' in 'HLIT_TicketingMVC.Controllers.TicketController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.<br>Parameter name: parameters</title>

so check all that, and post your controller method signature in case that's part of the issue

You can use the built-in Dir function or the FileSystemObject.

• Dir Function: VBA: Dir Function

• FileSystemObject: VBA: FileSystemObject - Files Collection

They each have their own strengths and weaknesses.

Dir Function

The Dir Function is a built-in, lightweight method to get a list of files. The benefits for using it are:

• Easy to Use
• Good performance (it's fast)
• Wildcard support

The trick is to understand the difference between calling it with or without a parameter. Here is a very simple example to demonstrate:

Public Sub ListFilesDir(ByVal sPath As String, Optional ByVal sFilter As String)

    Dim sFile As String

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file name
    sFile = Dir(sPath & sFilter)

   'call it again until there are no more files
    Do Until sFile = ""

        Debug.Print sFile

        'subsequent calls without param return next file name
        sFile = Dir

    Loop

End Sub

If you alter any of the files inside the loop, you will get unpredictable results. It is better to read all the names into an array of strings before doing any operations on the files. Here is an example which builds on the previous one. This is a Function that returns a String Array:

Public Function GetFilesDir(ByVal sPath As String, _
    Optional ByVal sFilter As String) As String()

    'dynamic array for names
    Dim aFileNames() As String
    ReDim aFileNames(0)

    Dim sFile As String
    Dim nCounter As Long

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file
    sFile = Dir(sPath & sFilter)

    'call it until there is no filename returned
    Do While sFile <> ""

        'store the file name in the array
        aFileNames(nCounter) = sFile

        'subsequent calls without param return next file
        sFile = Dir

        'make sure your array is large enough for another
        nCounter = nCounter + 1
        If nCounter > UBound(aFileNames) Then
            'preserve the values and grow by reasonable amount for performance
            ReDim Preserve aFileNames(UBound(aFileNames) + 255)
        End If

    Loop

    'truncate the array to correct size
    If nCounter < UBound(aFileNames) Then
        ReDim Preserve aFileNames(0 To nCounter - 1)
    End If

    'return the array of file names
    GetFilesDir = aFileNames()

End Function

File System Object

The File System Object is a library for IO operations which supports an object-model for manipulating files. Pros for this approach:

• Intellisense
• Robust object-model

You can add a reference to to "Windows Script Host Object Model" (or "Windows Scripting Runtime") and declare your objects like so:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As FileSystemObject
    Dim oFolder As Folder
    Dim oFile As File

    Set oFSO = New FileSystemObject
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

If you don't want intellisense you can do like so without setting a reference:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As Object
    Dim oFolder As Object
    Dim oFile As Object

    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

As David Olsson has said, you can use HTML in your string resources:

<resource>
    <string name="my_string">A string with <i>actual</i> <b>formatting</b>!</string>
</resources>

Then if you use getText(R.string.my_string) rather than getString(R.string.my_string) you get back a CharSequence rather than a String that contains the formatting embedded.

Starting with SQL Server 2012:

SELECT DATEADD(DAY,1,EOMONTH(@mydate,-1))

Just put this code in KeyTyped event:

    if ((jtextField.getText() + evt.getKeyChar()).length() > 20) {
        evt.consume();
    }

Where "20" is the maximum number of characters that you want.

Fake IE10 to install Visual Studio 2013

Visual Studio 2013 requires Internet Explorer 10. If you try to install it on Windows 7 with IE8 you get the following error This version of Visual Studio requires Internet Explorer 10”. The value that the VS 2013 installer checks is svcVersion in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorerkey on 32-bit Windows and HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer on 64-bit Windows. Any value >= 10.0.0.0 makes the installer happy.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer]
"svcVersion"="10.0.0.0"

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer]
"svcVersion"="10.0.0.0"

How I account for my site being behind an Amazon AWS Elastic Load Balancer (ELB):

public class GetPublicIp {

    /// <summary>
    /// account for possbility of ELB sheilding the public IP address
    /// </summary>
    /// <returns></returns>
    public static string Execute() {
        try {
            Console.WriteLine(string.Join("|", new List<object> {
                    HttpContext.Current.Request.UserHostAddress,
                    HttpContext.Current.Request.Headers["X-Forwarded-For"],
                    HttpContext.Current.Request.Headers["REMOTE_ADDR"]
                })
            );

            var ip = HttpContext.Current.Request.UserHostAddress;
            if (HttpContext.Current.Request.Headers["X-Forwarded-For"] != null) {
                ip = HttpContext.Current.Request.Headers["X-Forwarded-For"];
                Console.WriteLine(ip + "|X-Forwarded-For");
            }
            else if (HttpContext.Current.Request.Headers["REMOTE_ADDR"] != null) {
                ip = HttpContext.Current.Request.Headers["REMOTE_ADDR"];
                Console.WriteLine(ip + "|REMOTE_ADDR");
            }
            return ip;
        }
        catch (Exception ex) {
            Console.Error.WriteLine(ex.Message);
        }
        return null;
    }
}

The recommended way to create random integers with NumPy these days is to use numpy.random.Generator.integers. (documentation)

import numpy as np
import pandas as pd

rng = np.random.default_rng()
df = pd.DataFrame(rng.integers(0, 100, size=(100, 4)), columns=list('ABCD'))
df
----------------------
      A    B    C    D
 0   58   96   82   24
 1   21    3   35   36
 2   67   79   22   78
 3   81   65   77   94
 4   73    6   70   96
... ...  ...  ...  ...
95   76   32   28   51
96   33   68   54   77
97   76   43   57   43
98   34   64   12   57
99   81   77   32   50
100 rows × 4 columns

To copy all files, including hidden files use:

cp -r /home/server/folder/test/. /home/server/

This is an example that will clear the contents of cell "A1" (or more if the selection type is xllastcell, etc.). All done without having to select the cells.

Application.GoTo Reference:=Workbook(WorkbookName).Worksheets(WorksheetName).Range("A1")
Range(Selection,selection(selectiontype)).clearcontents 

I am guessing there is a fundamental reason for the change, it isn't merely cosmetic to make the old interpretation clearer: that reason is concurrency. Unspecified order of elaboration is merely selection of one of several possible serial orderings, this is quite different to before and after orderings, because if there is no specified ordering, concurrent evaluation is possible: not so with the old rules. For example in:

f (a,b)

previously either a then b, or, b then a. Now, a and b can be evaluated with instructions interleaved or even on different cores.

On the HTTP Response where you are returning the PDF file, ensure the content disposition header looks like:

Content-Disposition: attachment; filename=quot.pdf;

See content-disposition on the wikipedia MIME page.

Parallel.ForEach will optimize(may not even start new threads) and block until the loop is finished, and Task.Factory will explicitly create a new task instance for each item, and return before they are finished (asynchronous tasks). Parallel.Foreach is much more efficient.

The project facets should be derived automagically by the M2Eclipse plugin from the POM configuration. If you make some changes to the POM and need Eclipse to take them into account, right-click on your project, then go to Maven > Update Project Configuration. You should not set project facets manually.

<div class="info">
   <h2>Takvim</h2>
   <a href="item-list.php"> Click Me !</a>
</div>


$(document).delegate("div.info", "click", function() {
   window.location = $(this).find("a").attr("href");
});

Use this function:

function repeatElement(element, count) {
    return Array(count).fill(element)
}

>>> repeatElement('#', 5).join('')
"#####"

Or for a more compact version:

const repeatElement = (element, count) =>
    Array(count).fill(element)

>>> repeatElement('#', 5).join('')
"#####"

Or for a curry-able version:

const repeatElement = element => count =>
    Array(count).fill(element)

>>> repeatElement('#')(5).join('')
"#####"

You can use this function with a list:

const repeatElement = (element, count) =>
    Array(count).fill(element)

>>> ['a', 'b', ...repeatElement('c', 5)]
['a', 'b', 'c', 'c', 'c', 'c', 'c']

public static void hanoi(int number, String source, String aux, String dest)
{
    if (number == 1)
    {
        System.out.println(source + " - > "+dest);
    }
    else{
        hanoi(number -1, source, dest, aux);
        hanoi(1, source, aux, dest);
        hanoi(number -1, aux, source, dest);
    }
}

You need to create a CustomListAdapter.

public class CustomListAdapter extends ArrayAdapter <String> {

    private Context mContext;
    private int id;
    private List <String>items ;

    public CustomListAdapter(Context context, int textViewResourceId , List<String> list ) 
    {
        super(context, textViewResourceId, list);           
        mContext = context;
        id = textViewResourceId;
        items = list ;
    }

    @Override
    public View getView(int position, View v, ViewGroup parent)
    {
        View mView = v ;
        if(mView == null){
            LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            mView = vi.inflate(id, null);
        }

        TextView text = (TextView) mView.findViewById(R.id.textView);

        if(items.get(position) != null )
        {
            text.setTextColor(Color.WHITE);
            text.setText(items.get(position));
            text.setBackgroundColor(Color.RED); 
            int color = Color.argb( 200, 255, 64, 64 );
                text.setBackgroundColor( color );

        }

        return mView;
    }

}

The list item looks like this (custom_list.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content">
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/textView"
    android:textSize="20px" android:paddingTop="10dip" android:paddingBottom="10dip"/>
</LinearLayout>

Use the TextView api's to decorate your text to your liking

and you will be using it like this

listAdapter = new CustomListAdapter(YourActivity.this , R.layout.custom_list , mList);
mListView.setAdapter(listAdapter);

If you only want to ssh a few times, such as on a borrowed or shared computer, try:

ssh buck@hostname

or

ssh -l buck hostname

SELECT COUNT(*) FROM information_schema.tables

You could also use the CountDownLatch object like explained here.

I have to mention the path.py library, which I use very often.

Fetching the immediate subdirectories become as simple as that:

my_dir.dirs()

The full working example is:

from path import Path

my_directory = Path("path/to/my/directory")

subdirs = my_directory.dirs()

NB: my_directory still can be manipulated as a string, since Path is a subclass of string, but providing a bunch of useful methods for manipulating paths

href in an attribute, so you can change it using pure JavaScript, but if you already have jQuery injected in your page, don't worry, I will show it both ways:

Imagine you have this href below:

<a id="ali" alt="Ali" href="http://dezfoolian.com.au">Alireza Dezfoolian</a>

And you like to change it the link...

Using pure JavaScript without any library you can do:

document.getElementById("ali").setAttribute("href", "https://stackoverflow.com");

But also in jQuery you can do:

$("#ali").attr("href", "https://stackoverflow.com");

or

$("#ali").prop("href", "https://stackoverflow.com");

In this case, if you already have jQuery injected, probably jQuery one look shorter and more cross-browser...but other than that I go with the JS one...

Default Export (export default)

// MyClass.ts -- using default export
export default class MyClass { /* ... */ }

The main difference is that you can only have one default export per file and you import it like so:

import MyClass from "./MyClass";

You can give it any name you like. For example this works fine:

import MyClassAlias from "./MyClass";

Named Export (export)

// MyClass.ts -- using named exports
export class MyClass { /* ... */ }
export class MyOtherClass { /* ... */ }

When you use a named export, you can have multiple exports per file and you need to import the exports surrounded in braces:

import { MyClass } from "./MyClass";

Note: Adding the braces will fix the error you're describing in your question and the name specified in the braces needs to match the name of the export.

Or say your file exported multiple classes, then you could import both like so:

import { MyClass, MyOtherClass } from "./MyClass";
// use MyClass and MyOtherClass

Or you could give either of them a different name in this file:

import { MyClass, MyOtherClass as MyOtherClassAlias } from "./MyClass";
// use MyClass and MyOtherClassAlias

Or you could import everything that's exported by using * as:

import * as MyClasses from "./MyClass";
// use MyClasses.MyClass and MyClasses.MyOtherClass here

Which to use?

In ES6, default exports are concise because their use case is more common; however, when I am working on code internal to a project in TypeScript, I prefer to use named exports instead of default exports almost all the time because it works very well with code refactoring. For example, if you default export a class and rename that class, it will only rename the class in that file and not any of the other references in other files. With named exports it will rename the class and all the references to that class in all the other files.

It also plays very nicely with barrel files (files that use namespace exports—export *—to export other files). An example of this is shown in the "example" section of this answer.

Note that my opinion on using named exports even when there is only one export is contrary to the TypeScript Handbook—see the "Red Flags" section. I believe this recommendation only applies when you are creating an API for other people to use and the code is not internal to your project. When I'm designing an API for people to use, I'll use a default export so people can do import myLibraryDefaultExport from "my-library-name";. If you disagree with me about doing this, I would love to hear your reasoning.

That said, find what you prefer! You could use one, the other, or both at the same time.

Additional Points

A default export is actually a named export with the name default, so if the file has a default export then you can also import by doing:

import { default as MyClass } from "./MyClass";

And take note these other ways to import exist: 

import MyDefaultExportedClass, { Class1, Class2 } from "./SomeFile";
import MyDefaultExportedClass, * as Classes from "./SomeFile";
import "./SomeFile"; // runs SomeFile.js without importing any exports

On Spanish (Spain) keyboard with VS2012 is Ctrl + ¡ as stated by @Keith but if you use Ctrl + ¿ (typed as Ctrl + Shift + ¡) then goes to Matching Brace plus selects all the code within the two braces and then you can't go again to the other brace.

I have also met this issue and wasted a lot of time debugging it.

First, make sure that the path you provide is valid, i.e., there is an image in that path.

Next, you should be aware that Opencv doesn't support image paths which contain unicode characters (see ref). If your image path contains Unicode characters, you can use the following code to read the image:

import numpy as np
import cv2

# img is in BGR format if the underlying image is a color image
img = cv2.imdecode(np.fromfile(im_path, dtype=np.uint8), cv2.IMREAD_UNCHANGED)

We are seeing 404 errors in our logs when using //somedomain.com as references to JS files.

The references that cause the 404s come out looking like this: ref:

<script src="//somedomain.com/somescript.js" />

404 request:

http://mydomain.com//somedomain.com/somescript.js

With these showing up regularly in our web server logs, it is safe to say that: All browsers and Bots DO NOT honor RFC 3986 section 4.2. The safest bet is to include the protocol whenever possible.

To draw text directly on canvas do the following:

1. Create a member Paint object in myImageView constructor

   Paint mTextPaint = new Paint();
   

2. Use canvas.drawText in your myImageView.onDraw() method:

   canvas.drawText("My fancy text", xpos, ypos, mTextPaint);
   

Explore Paint and Canvas class documentation to add fancy effects.

The localStorage and sessionStorage can only handle strings. You can extend the default storage-objects to handle arrays and objects. Just include this script and use the new methods:

Storage.prototype.setObj = function(key, obj) {
    return this.setItem(key, JSON.stringify(obj))
}
Storage.prototype.getObj = function(key) {
    return JSON.parse(this.getItem(key))
}

Use localStorage.setObj(key, value) to save an array or object and localStorage.getObj(key) to retrieve it. The same methods work with the sessionStorage object.

If you just use the new methods to access the storage, every value will be converted to a JSON-string before saving and parsed before it is returned by the getter.

Just logged in to the server and type below command

locate catalina.out

It will show all the locations where catalina file exist within this server.

Look at the open function in Perl - especially the variants using a '|' (pipe) in the arguments. Done correctly, you'll get a file handle that you can use to read the output of the command. The back tick operators also do this.

You might also want to review whether Perl has access to the C functions that the command itself uses. For example, for ls -a, you could use the opendir function, and then read the file names with the readdir function, and finally close the directory with (surprise) the closedir function. This has a number of benefits - precision probably being more important than speed. Using these functions, you can get the correct data even if the file names contain odd characters like newline.

One solution I adopted--for use with java code, but the concept is the same with mexFunctions, just messier--is to return a FutureValue and then loop while FutureValue.finished() or whatever returns true. The actual code executes in another thread/process. Wrapping a try,catch around that and a FutureValue.cancel() in the catch block works for me.

In the case of mex functions, you will need to return somesort of pointer (as an int) that points to a struct/object that has all the data you need (native thread handler, bool for complete etc). In the case of a built in mexFunction, your mexFunction will most likely need to call that mexFunction in the separate thread. Mex functions are just DLLs/shared objects after all.

PseudoCode

FV = mexLongProcessInAnotherThread();
try
  while ~mexIsDone(FV);
    java.lang.Thread.sleep(100); %pause has a memory leak
    drawnow; %allow stdout/err from mex to display in command window
  end
catch
  mexCancel(FV);
end

This error happened to me because I had @@model instead of @model... copy & paste error in my case. Changing to @model fixed it for me.

You are trying to execute an asynchronous function in a synchronous way, which is unfortunately not possible in Javascript.

As you guessed correctly, the roomId=results.... is executed when the loading from the DB completes, which is done asynchronously, so AFTER the resto of your code is completed.

Look at this article, it talks about .insert and not .find, but the idea is the same : http://metaduck.com/01-asynchronous-iteration-patterns.html

for the sake of completeness, you could use:

(DT_STR,8, 1252) (YEAR(GetDate()) * 10000 + MONTH(GetDate()) * 100 + DAY(GetDate()))

for YYYYMMDD or

RIGHT("000000" + (DT_STR,8, 1252) (DAY(GetDate()) * 1000000 + MONTH(GetDate()) * 10000 + YEAR(GetDate())), 8)

for DDMMYYYY (without hyphens). If you want / need the date as integer (e.g. for _key-columns in DWHs), just remove the DT_STR / RIGTH function and do just the math.

How are you loading this page? Is it getting anything on POST to load? If it's not, then the $name = $_POST['Name']; assignation doesn't have any 'Name' on POST.

I have found better option,

<style type="text/css">
    .form {
        margin: 0 auto;
        width: 210px;
    }
    .form label{
        display: inline-block;
        text-align: right;
        float: left;
    }
    .form input{
        display: inline-block;
        text-align: left;
        float: right;
    }
</style>

For Angular9+, according to this, you can use:

.mat-select-panel {
    background: red;
    ....
}

Demo

1. Use ::ng-deep:

Use the /deep/ shadow-piercing descendant combinator to force a style down through the child component tree into all the child component views. The /deep/ combinator works to any depth of nested components, and it applies to both the view children and content children of the component. Use /deep/, >>> and ::ng-deep only with emulated view encapsulation. Emulated is the default and most commonly used view encapsulation. For more information, see the Controlling view encapsulation section. The shadow-piercing descendant combinator is deprecated and support is being removed from major browsers and tools. As such we plan to drop support in Angular (for all 3 of /deep/, >>> and ::ng-deep). Until then ::ng-deep should be preferred for a broader compatibility with the tools.

CSS:

::ng-deep .mat-select-content{
    width:2000px;
    background-color: red;
    font-size: 10px;   
}

DEMO

2. Use ViewEncapsulation

... component CSS styles are encapsulated into the component's view and don't affect the rest of the application. To control how this encapsulation happens on a per component basis, you can set the view encapsulation mode in the component metadata. Choose from the following modes: .... None means that Angular does no view encapsulation. Angular adds the CSS to the global styles. The scoping rules, isolations, and protections discussed earlier don't apply. This is essentially the same as pasting the component's styles into the HTML.

None value is what you will need to break the encapsulation and set material style from your component. So can set on the component's selector:

Typscript:

  import {ViewEncapsulation } from '@angular/core';
  ....
  @Component({
        ....
        encapsulation: ViewEncapsulation.None
 })  

CSS

.mat-select-content{
    width:2000px;
    background-color: red;
    font-size: 10px;
}

DEMO

3. Set class style in style.css

This time you have to 'force' styles with !important too.

style.css

 .mat-select-content{
   width:2000px !important;
   background-color: red !important;
   font-size: 10px !important;
 } 

DEMO

4. Use inline style

<mat-option style="width:2000px; background-color: red; font-size: 10px;" ...>

DEMO

Try:

name = "^aH^ai"
name = name:gsub("%^a", "")

I have the same issue with you and I have change something in my server

you might try this

const root = require("path").join(__dirname, "./build");
app.use(express.static(root));
app.get("*", (req, res) => {
  res.sendFile("index.html", { root });
});

Below can be 2 reasons for this issue:

1. Backup taken on SQL 2012 and Restore Headeronly was done in SQL 2008 R2

2. Backup media is corrupted.

If we run below command, we can find actual error always:

restore headeronly
from disk = 'C:\Users\Public\Database.bak'

Editted:

In order to flex only the center text, a different approach can be taken - Unflex the other views.

• Let flexDirection remain at 'column'
• remove the alignItems : 'center' from container
• add alignSelf:'center' to the textviews that you don't want to flex

You can wrap the Text component in a View component and give the View a flex of 1.

The flex will give :

100% width if the flexDirection:'row' in styles.container

100% height if the flexDirection:'column' in styles.container

Don't know if anyone is still looking here, but you can do this by going to Window menu > Preferences, then open the General list, choose keys. Scroll down the list of keys until you see "Shift Left". Click that. Below that you'll see some boxes, one of which lets you bind a key. It won't accept Shift-Tab, so I bound it to Shift-`. Apply-and-close and you're all set.

I am able to read both the IMEI's from OnePlus 2 Phone

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                TelephonyManager manager = (TelephonyManager) getActivity().getSystemService(Context.TELEPHONY_SERVICE);
                Log.i(TAG, "Single or Dual Sim " + manager.getPhoneCount());
                Log.i(TAG, "Default device ID " + manager.getDeviceId());
                Log.i(TAG, "Single 1 " + manager.getDeviceId(0));
                Log.i(TAG, "Single 2 " + manager.getDeviceId(1));
            }

I usually use set_time_limit(30) within the main loop (so each loop iteration is limited to 30 seconds rather than the whole script).

I do this in multiple database update scripts, which routinely take several minutes to complete but less than a second for each iteration - keeping the 30 second limit means the script won't get stuck in an infinite loop if I am stupid enough to create one.

I must admit that my choice of 30 seconds for the limit is somewhat arbitrary - my scripts could actually get away with 2 seconds instead, but I feel more comfortable with 30 seconds given the actual application - of course you could use whatever value you feel is suitable.

Hope this helps!

Using the suggested Maven properties plugin I was able to read in a buildNumber.properties file that I use to version my builds.

If anyone wonders for the Array version, it goes like this:

int i = Array.FindIndex(yourArray, x => x == itemYouWant);

I resolved it by changing X64 to : Right click on project -> Properties -> Build -> Platform target -> Any CPU

A tail recursion is a recursive function where the function calls itself at the end ("tail") of the function in which no computation is done after the return of recursive call. Many compilers optimize to change a recursive call to a tail recursive or an iterative call.

Consider the problem of computing factorial of a number.

A straightforward approach would be:

  factorial(n):

    if n==0 then 1

    else n*factorial(n-1)

Suppose you call factorial(4). The recursion tree would be:

       factorial(4)
       /        \
      4      factorial(3)
     /             \
    3          factorial(2)
   /                  \
  2                factorial(1)
 /                       \
1                       factorial(0)
                            \
                             1    

The maximum recursion depth in the above case is O(n).

However, consider the following example:

factAux(m,n):
if n==0  then m;
else     factAux(m*n,n-1);

factTail(n):
   return factAux(1,n);

Recursion tree for factTail(4) would be:

factTail(4)
   |
factAux(1,4)
   |
factAux(4,3)
   |
factAux(12,2)
   |
factAux(24,1)
   |
factAux(24,0)
   |
  24

Here also, maximum recursion depth is O(n) but none of the calls adds any extra variable to the stack. Hence the compiler can do away with a stack.

There is no "standard" library function to do this. The standard (perhaps surprisingly) does not actually recognise the concept of a "keyboard", albeit it does have a standard for "console input".

There are various ways to achieve it on different operating systems (see herohuyongtao's solution) but it is not portable across all platforms that support keyboard input.

Remember that C++ (and C) are devised to be languages that can run on embedded systems that do not have keyboards. (Having said that, an embedded system might not have various other devices that the standard library supports).

This matter has been debated for a long time.

For anyone else getting

Nginx 403 error: directory index of [folder] is forbidden

when using index.php while index.html works perfectly and having included index.php in the index in the server block of their site config in sites-enabled

server {
    listen 80;

    # this path MUST be exactly as docker-compose php volumes
    root /usr/share/nginx/html;

    index index.php

    ...
}

Make sure your nginx.conf file at /etc/nginx/nginx.conf actually loads your site config in the http block...

http {

    ...

    include /etc/nginx/conf.d/*.conf;

    # Load our websites config 
    include /etc/nginx/sites-enabled/*;
}

The first ten lowercase letters are string.lowercase[:10] (if you have imported the standard library module string previously, of course;-).

Other ways to "make a string of 10 characters": 'x'*10 (all the ten characters will be lowercase xs;-), ''.join(chr(ord('a')+i) for i in xrange(10)) (the first ten lowercase letters again), etc, etc;-).

"Dangerous" and "Security risk" are not the first things that spring to mind when people mention iframes … but they can be used in clickjacking attacks.

If you have php 5.3+, you can use an anonymous function like so:

add_filter( 'login_redirect', function() { return site_url('news'); } );

It's part of the ES6 module system, described here. There is a helpful example in that documentation, also:

If a module defines a default export:

export default function() { console.log("hello!") }

then you can import that default export by omitting the curly braces:

import foo from "foo";
foo(); // hello!

Update: As of June 2015, the module system is defined in §15.2 and the export syntax in particular is defined in §15.2.3 of the ECMAScript 2015 specification.

I Think that the problem is about encoding. That's why removing first line(with encoding byte) might solve the problem.

My solution for Data at the root level is invalid. Line 1, position 1. in XDocument.Parse(xmlString) was replacing it with XDocument.Load( new MemoryStream( xmlContentInBytes ) );

I've noticed that my xml string looked ok:

<?xml version="1.0" encoding="utf-8"?>

but in different text editor encoding it looked like this:

?<?xml version="1.0" encoding="utf-8"?>

At the end i did not need the xml string but xml byte[]. If you need to use the string you should look for "invisible" bytes in your string and play with encodings to adjust the xml content for parsing or loading.

Hope it will help

Just do it like this:

if(!document.getElementById("someId") { /Some code. Note the NOT (!) in the expresion/ };

If element with id "someId" does not exist expresion will return TRUE (NOT FALSE === TRUE) or !false === true;

try this code:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <meta name="format-detection" content="telephone-no">
        <meta name="viewport" content="user-scalable=no, initial-scale=1, minimum-scale=1, maximum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi">
        <title>Test</title>
    </head>
    <body>
      <script>
var createPerson = function (name) {
    var person;
    if (!document.getElementById(name)) {
        alert("Element does not exist. Let's create it.");
      person = document.createElement("div");
//add argument name as the ID of the element
      person.id = name;
//append element to the body of the document
      document.body.appendChild(person);
    } else {
        alert("Element exists. Lets get it by ID!");
      person = document.getElementById(name);
    }
    person.innerHTML = "HI THERE!";

};
//run the function.
createPerson("someid");
          </script>
       </body>
</html>

Try this in your browser and it should alert "Element does not exist. Let's create it."

Now add

<div id="someid"></div>

to the body of the page and try again. Voila! :)

This is good for taking multiple line input

import java.util.Scanner;
public class JavaApp {
    public static void main(String[] args){
        Scanner scanner = new Scanner(System.in);
        String line;
        while(true){
            line = scanner.nextLine();
            System.out.println(line);
            if(line.equals("")){
                break;
            }
        }
    }  
}

My guess is that $_.Name does not exist.

If I were you, I'd bring the script into the ISE and run it line for line till you get there then take a look at the value of $_

Check if the deployment target in the General section of the project settings, is greater than that of your device's iOS version.

If yes then you need to update the version of your device to at least the deployment target version. in order for you to be able to install the application on your device.

You probably would have specified a wrong package and the package hierarchy would not be right. Look below

The ide would highlight the wrong path in that case.

One issue with REPLACE will be where city names contain the district name. You can use something like.

SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM   dbo.tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004' 

I came up with a slightly different solution. It's a bit hack-ish, but here is the mapping:

<servlet-mapping>   
    <servlet-name>default</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.jpg</url-pattern>
</servlet-mapping>
<servlet-mapping>
 <servlet-name>default</servlet-name>
    <url-pattern>*.png</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.css</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>myAppServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

This basically just maps all content files by extension to the default servlet, and everything else to "myAppServlet".

It works in both Jetty and Tomcat.

Extract private method to another class, test on that class; read more about SRP principle (Single Responsibility Principle)

It seem that you need extract to the private method to another class; in this should be public. Instead of trying to test on the private method, you should test public method of this another class.

We has the following scenario:

Class A
+ outputFile: Stream
- _someLogic(arg1, arg2) 

We need to test the logic of _someLogic; but it seem that Class A take more role than it need(violate the SRP principle); just refactor into two classes

Class A1
    + A1(logicHandler: A2) # take A2 for handle logic
    + outputFile: Stream
Class A2
    + someLogic(arg1, arg2) 

In this way someLogic could be test on A2; in A1 just create some fake A2 then inject to constructor to test that A2 is called to the function named someLogic.

This will give you one last document for a collection

db.collectionName.findOne({}, {sort:{$natural:-1}})

$natural:-1 means order opposite of the one that records are inserted in.

Edit: For all the downvoters, above is a Mongoose syntax, mongo CLI syntax is: db.collectionName.find({}).sort({$natural:-1}).limit(1)

(copy-paste/adapted from https://stackoverflow.com/a/24048772/1733117).

First you can subclass urllib2.BaseHandler or urllib2.HTTPBasicAuthHandler, and implement http_request so that each request has the appropriate Authorization header.

import urllib2
import base64

class PreemptiveBasicAuthHandler(urllib2.HTTPBasicAuthHandler):
    '''Preemptive basic auth.

    Instead of waiting for a 403 to then retry with the credentials,
    send the credentials if the url is handled by the password manager.
    Note: please use realm=None when calling add_password.'''
    def http_request(self, req):
        url = req.get_full_url()
        realm = None
        # this is very similar to the code from retry_http_basic_auth()
        # but returns a request object.
        user, pw = self.passwd.find_user_password(realm, url)
        if pw:
            raw = "%s:%s" % (user, pw)
            auth = 'Basic %s' % base64.b64encode(raw).strip()
            req.add_unredirected_header(self.auth_header, auth)
        return req

    https_request = http_request

Then if you are lazy like me, install the handler globally

api_url = "http://api.foursquare.com/"
api_username = "johndoe"
api_password = "some-cryptic-value"

auth_handler = PreemptiveBasicAuthHandler()
auth_handler.add_password(
    realm=None, # default realm.
    uri=api_url,
    user=api_username,
    passwd=api_password)
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)

I would follow official projects like tar as an example. In my opinion help msg. needs to be simple and descriptive as possible. Examples of use are good too. There is no real need for "standard help".

PHPmyadmin also accepts compressed files in gzip format, so you can gzip the file (Use 7Zip if you don't have any) and upload the zipped file. Since its a text file, it will have a good compress ratio.

Yet another approach.

The following is now possible thanks to the recent PHP 7 version.

$theStdClass = (object) [
  'a' => 'Alpha',
  'b' => 'Bravo',
  'c' => 'Charlie',
  'd' => 'Delta',
];

$foo = new class($theStdClass)  {
  public function __construct($data) {
    if (!is_array($data)) {
      $data = (array) $data;
    }

    foreach ($data as $prop => $value) {
      $this->{$prop} = $value;
    }
  }
  public function word4Letter($letter) {
    return $this->{$letter};
  }
};

print $foo->word4Letter('a') . PHP_EOL; // Alpha
print $foo->word4Letter('b') . PHP_EOL; // Bravo
print $foo->word4Letter('c') . PHP_EOL; // Charlie
print $foo->word4Letter('d') . PHP_EOL; // Delta
print $foo->word4Letter('e') . PHP_EOL; // PHP Notice:  Undefined property

In this example, $foo is being initialized as an anonymous class that takes one array or stdClass as only parameter for the constructor.

Eventually, we loop through the each items contained in the passed object and dynamically assign then to an object's property.

To make this approch event more generic, you can write an interface or a Trait that you will implement in any class where you want to be able to cast an stdClass.

I think is better to change the logical function in the plugin. Around row 552 i change this:

            var zIndex = parseInt(this.element.parents().filter(function(){
                return $(this).css('z-index') !== 'auto';
            }).first().css('z-index'))+10;

into this:

            var zIndex = parseInt(this.element.parents().filter(function(){
                return $(this).css('z-index') !== 'auto';
            }).first().css('z-index')) + 10 * 1000; //think is enought

Use the flex-grow property to make a flex item consume free space on the main axis.

This property will expand the item as much as possible, adjusting the length to dynamic environments, such as screen re-sizing or the addition / removal of other items.

A common example is flex-grow: 1 or, using the shorthand property, flex: 1.

Hence, instead of width: 96% on your div, use flex: 1.

You wrote:

So at the moment, it's set to 96% which looks OK until you really squash the screen - then the right hand div gets a bit starved of the space it needs.

The squashing of the fixed-width div is related to another flex property: flex-shrink

By default, flex items are set to flex-shrink: 1 which enables them to shrink in order to prevent overflow of the container.

To disable this feature use flex-shrink: 0.

For more details see The flex-shrink factor section in the answer here:

• What are the differences between flex-basis and width?

Learn more about flex alignment along the main axis here:

• In CSS Flexbox, why are there no "justify-items" and "justify-self" properties?

Learn more about flex alignment along the cross axis here:

• How does flex-wrap work with align-self, align-items and align-content?

Here's what I've found. If you want an app to open on your secondary monitor by default do the following:

1. Open the application.
2. Re-size the window so that it is not maximized or minimized.
3. Move the window to the monitor you want it to open on by default.
4. Close the application.  Do not re-size prior to closing.
5. Open the application.
   It should open on the monitor you just moved it to and closed it on.
6. Maximize the window.

The application will now open on this monitor by default. If you want to change it to another monitor, just follow steps 1-6 again.

here is a short one liner to accomplish this:

request.META.get('HTTP_X_FORWARDED_FOR', request.META.get('REMOTE_ADDR', '')).split(',')[0].strip()

I try this clipboard 0.0.4 and it works well.

https://pypi.python.org/pypi/clipboard/0.0.4

import clipboard
clipboard.copy("abc")  # now the clipboard content will be string "abc"
text = clipboard.paste()  # text will have the content of clipboard

The backgroundTint attribute will help you to add a tint(shade) to the background. You can provide a color value for the same in the form of - "#rgb", "#argb", "#rrggbb", or "#aarrggbb".

The backgroundTintMode on the other hand will help you to apply the background tint. It must have constant values like src_over, src_in, src_atop, etc.

Refer this to get a clear idea of the the constant values that can be used. Search for the backgroundTint attribute and the description along with various attributes will be available.

You can do this with transition events, so you build two CSS classes for the transition, one holding the animation other, holding the display none state. And you switch them after the animation is ended? In my case I can display the divs again if I press a button, and remove both classes.

Try the snippet below...

$(document).ready(function() {_x000D_
  // Assign transition event_x000D_
  $("table").on("animationend webkitAnimationEnd", ".visibility_switch_off", function(event) {_x000D_
    // We check if this is the same animation we want_x000D_
    if (event.originalEvent.animationName == "col_hide_anim") {_x000D_
      // After the animation we assign this new class that basically hides the elements._x000D_
      $(this).addClass("animation-helper-display-none");_x000D_
    }_x000D_
_x000D_
  });_x000D_
_x000D_
  $("button").click(function(event) {_x000D_
_x000D_
    $("table tr .hide-col").toggleClass(function() {_x000D_
      // We switch the animation class in a toggle fashion..._x000D_
      // and we know in that after the animation end, there_x000D_
      // is will the animation-helper-display-none extra_x000D_
      // class, that we nee to remove, when we want to_x000D_
      // show the elements again, depending on the toggle_x000D_
      // state, so we create a relation between them._x000D_
      if ($(this).is(".animation-helper-display-none")) {_x000D_
        // I'm toggling and there is already the above class, then_x000D_
        // what we want it to show the elements , so we remove_x000D_
        // both classes..._x000D_
        return "visibility_switch_off animation-helper-display-none";_x000D_
      }_x000D_
      else {_x000D_
        // Here we just want to hide the elements, so we just_x000D_
        // add the animation class, the other will be added_x000D_

It usually happens when the certificate does not match with the host name.

The solution would be to contact the host and ask it to fix its certificate.
Otherwise you can turn off cURL's verification of the certificate, use the -k (or --insecure) option.
Please note that as the option said, it is insecure. You shouldn't use this option because it allows man-in-the-middle attacks and defeats the purpose of HTTPS.

What is that BasePagerAdapter? You should use one of the standard pager adapters -- either FragmentPagerAdapter or FragmentStatePagerAdapter, depending on whether you want Fragments that are no longer needed by the ViewPager to either be kept around (the former) or have their state saved (the latter) and re-created if needed again.

Sample code for using ViewPager can be found here

It is true that the management of fragments in a view pager across activity instances is a little complicated, because the FragmentManager in the framework takes care of saving the state and restoring any active fragments that the pager has made. All this really means is that the adapter when initializing needs to make sure it re-connects with whatever restored fragments there are. You can look at the code for FragmentPagerAdapter or FragmentStatePagerAdapter to see how this is done.

Your question as I understand it is divided in two parts, part one being you need a better understanding of the Naive Bayes classifier & part two being the confusion surrounding Training set.

In general all of Machine Learning Algorithms need to be trained for supervised learning tasks like classification, prediction etc. or for unsupervised learning tasks like clustering.

During the training step, the algorithms are taught with a particular input dataset (training set) so that later on we may test them for unknown inputs (which they have never seen before) for which they may classify or predict etc (in case of supervised learning) based on their learning. This is what most of the Machine Learning techniques like Neural Networks, SVM, Bayesian etc. are based upon.

So in a general Machine Learning project basically you have to divide your input set to a Development Set (Training Set + Dev-Test Set) & a Test Set (or Evaluation set). Remember your basic objective would be that your system learns and classifies new inputs which they have never seen before in either Dev set or test set.

The test set typically has the same format as the training set. However, it is very important that the test set be distinct from the training corpus: if we simply reused the training set as the test set, then a model that simply memorized its input, without learning how to generalize to new examples, would receive misleadingly high scores.

In general, for an example, 70% of our data can be used as training set cases. Also remember to partition the original set into the training and test sets randomly.

Now I come to your other question about Naive Bayes.

To demonstrate the concept of Naïve Bayes Classification, consider the example given below:

As indicated, the objects can be classified as either GREEN or RED. Our task is to classify new cases as they arrive, i.e., decide to which class label they belong, based on the currently existing objects.

Since there are twice as many GREEN objects as RED, it is reasonable to believe that a new case (which hasn't been observed yet) is twice as likely to have membership GREEN rather than RED. In the Bayesian analysis, this belief is known as the prior probability. Prior probabilities are based on previous experience, in this case the percentage of GREEN and RED objects, and often used to predict outcomes before they actually happen.

Thus, we can write:

Prior Probability of GREEN: number of GREEN objects / total number of objects

Prior Probability of RED: number of RED objects / total number of objects

Since there is a total of 60 objects, 40 of which are GREEN and 20 RED, our prior probabilities for class membership are:

Prior Probability for GREEN: 40 / 60

Prior Probability for RED: 20 / 60

Having formulated our prior probability, we are now ready to classify a new object (WHITE circle in the diagram below). Since the objects are well clustered, it is reasonable to assume that the more GREEN (or RED) objects in the vicinity of X, the more likely that the new cases belong to that particular color. To measure this likelihood, we draw a circle around X which encompasses a number (to be chosen a priori) of points irrespective of their class labels. Then we calculate the number of points in the circle belonging to each class label. From this we calculate the likelihood:

From the illustration above, it is clear that Likelihood of X given GREEN is smaller than Likelihood of X given RED, since the circle encompasses 1 GREEN object and 3 RED ones. Thus:

Although the prior probabilities indicate that X may belong to GREEN (given that there are twice as many GREEN compared to RED) the likelihood indicates otherwise; that the class membership of X is RED (given that there are more RED objects in the vicinity of X than GREEN). In the Bayesian analysis, the final classification is produced by combining both sources of information, i.e., the prior and the likelihood, to form a posterior probability using the so-called Bayes' rule (named after Rev. Thomas Bayes 1702-1761).

Finally, we classify X as RED since its class membership achieves the largest posterior probability.

You simply need to enclose your SELECT statements in parentheses to indicate that they are subqueries:

SET cityLat = (SELECT cities.lat FROM cities WHERE cities.id = cityID);

Alternatively, you can use MySQL's SELECT ... INTO syntax. One advantage of this approach is that both cityLat and cityLng can be assigned from a single table-access:

SELECT lat, lng INTO cityLat, cityLng FROM cities WHERE id = cityID;

However, the entire procedure can be replaced with a single self-joined SELECT statement:

SELECT   b.*, HAVERSINE(a.lat, a.lng, b.lat, b.lng) AS dist
FROM     cities AS a, cities AS b
WHERE    a.id = cityID
ORDER BY dist
LIMIT    10;

I had the following problem where I was fetching data from a database and wanted to display a string containing \n. None of the solutions above worked for me and I finally came up with a solution: https://stackoverflow.com/a/61484190/7251208

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?

Basically, you use the /B and /C options:

START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1

I used @LiorH's example and expanded it to:

@XmlRootElement(name="List")
public class JaxbList<T>{
    protected List<T> list;

    public JaxbList(){}

    public JaxbList(List<T> list){
        this.list=list;
    }

    @XmlElement(name="Item")
    public List<T> getList(){
        return list;
    }
}

Note, that it uses generics so you can use it with other classes than String. Now, the application code is simply:

    @GET
    @Path("/test2")
    public JaxbList test2(){
        List list=new Vector();
        list.add("a");
        list.add("b");
        return new JaxbList(list);
    }

Why doesn't this simple class exist in the JAXB package? Anyone see anything like it elsewhere?

Kotlin solution using context extension

fun Context.applyNewLocale(locale: Locale): Context {
    val config = this.resources.configuration
    val sysLocale = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        config.locales.get(0)
    } else {
        //Legacy
        config.locale
    }
    if (sysLocale.language != locale.language) {
        Locale.setDefault(locale)
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            config.setLocale(locale)
        } else {
            //Legacy
            config.locale = locale
        }
        resources.updateConfiguration(config, resources.displayMetrics)
    }
    return this
}

Usage

override fun attachBaseContext(newBase: Context?) {
    super.attachBaseContext(newBase?.applyNewLocale(Locale("es", "MX")))
}

Update - the answer below was written before C# 6 came along. In C# 6 you can write:

public class Foo
{
    public string Bar { get; set; } = "bar";
}

You can also write read-only automatically-implemented properties, which are only writable in the constructor (but can also be given a default initial value):

public class Foo
{
    public string Bar { get; }

    public Foo(string bar)
    {
        Bar = bar;
    }
}

It's unfortunate that there's no way of doing this right now. You have to set the value in the constructor. (Using constructor chaining can help to avoid duplication.)

Automatically implemented properties are handy right now, but could certainly be nicer. I don't find myself wanting this sort of initialization as often as a read-only automatically implemented property which could only be set in the constructor and would be backed by a read-only field.

This hasn't happened up until and including C# 5, but is being planned for C# 6 - both in terms of allowing initialization at the point of declaration, and allowing for read-only automatically implemented properties to be initialized in a constructor body.

Try using the non-breaking hyphen ‑. I've replaced the dash with that character in your jsfiddle, shrunk the frame down as small as it can go, and the line doesn't split there any more.

The accepted answer changes shape for 2d arrays. I present a solution here, using the Pandas dropna() functionality. It works for 1D and 2D arrays. In the 2D case you can choose weather to drop the row or column containing np.nan.

import pandas as pd
import numpy as np

def dropna(arr, *args, **kwarg):
    assert isinstance(arr, np.ndarray)
    dropped=pd.DataFrame(arr).dropna(*args, **kwarg).values
    if arr.ndim==1:
        dropped=dropped.flatten()
    return dropped

x = np.array([1400, 1500, 1600, np.nan, np.nan, np.nan ,1700])
y = np.array([[1400, 1500, 1600], [np.nan, 0, np.nan] ,[1700,1800,np.nan]] )


print('='*20+' 1D Case: ' +'='*20+'\nInput:\n',x,sep='')
print('\ndropna:\n',dropna(x),sep='')

print('\n\n'+'='*20+' 2D Case: ' +'='*20+'\nInput:\n',y,sep='')
print('\ndropna (rows):\n',dropna(y),sep='')
print('\ndropna (columns):\n',dropna(y,axis=1),sep='')

print('\n\n'+'='*20+' x[np.logical_not(np.isnan(x))] for 2D: ' +'='*20+'\nInput:\n',y,sep='')
print('\ndropna:\n',x[np.logical_not(np.isnan(x))],sep='')

Result:

==================== 1D Case: ====================
Input:
[1400. 1500. 1600.   nan   nan   nan 1700.]

dropna:
[1400. 1500. 1600. 1700.]


==================== 2D Case: ====================
Input:
[[1400. 1500. 1600.]
 [  nan    0.   nan]
 [1700. 1800.   nan]]

dropna (rows):
[[1400. 1500. 1600.]]

dropna (columns):
[[1500.]
 [   0.]
 [1800.]]


==================== x[np.logical_not(np.isnan(x))] for 2D: ====================
Input:
[[1400. 1500. 1600.]
 [  nan    0.   nan]
 [1700. 1800.   nan]]

dropna:
[1400. 1500. 1600. 1700.]

Starting with the code from the other question:

class MyClass {
  private static MyClass myClass = new MyClass();
  private static final Object obj = new Object();
  public MyClass() {
    System.out.println(obj); // will print null once
  }
}

A reference to this class will start initialization. First, the class will be marked as initialized. Then the first static field will be initialized with a new instance of MyClass(). Note that myClass is immediately given a reference to a blank MyClass instance. The space is there, but all values are null. The constructor is now executed and prints obj, which is null.

Now back to initializing the class: obj is made a reference to a new real object, and we're done.

If this was set off by a statement like: MyClass mc = new MyClass(); space for a new MyClass instance is again allocated (and the reference placed in mc). The constructor is again executed and again prints obj, which now is not null.

The real trick here is that when you use new, as in WhatEverItIs weii = new WhatEverItIs( p1, p2 ); weii is immediately given a reference to a bit of nulled memory. The JVM will then go on to initialize values and run the constructor. But if you somehow reference weii before it does so--by referencing it from another thread or or by referencing from the class initialization, for instance--you are looking at a class instance filled with null values.

Function ListRowCount(ByVal FirstCellName as String) as Long
    With thisworkbook.Names(FirstCellName).RefersToRange
        If isempty(.Offset(1,0).value) Then 
            ListRowCount = 1
        Else
            ListRowCount = .End(xlDown).row - .row + 1
        End If
    End With
End Function

But if you are damn sure there's nothing around the list, then just thisworkbook.Names(FirstCellName).RefersToRange.CurrentRegion.rows.count

In addition to Gilson PJ answer:

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

with

"scripts": {
    "build": "NODE_ENV=production webpack -p --config ./webpack.production.config.js"
},

cause that the it tries to uglify your code twice. See https://webpack.github.io/docs/cli.html#production-shortcut-p for more information.

You can fix this by removing the UglifyJsPlugin from plugins-array or add the OccurrenceOrderPlugin and remove the "-p"-flag. so one possible solution would be

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.OccurrenceOrderPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

and

"scripts": {
    "build": "NODE_ENV=production webpack --config ./webpack.production.config.js"
},

Just adding on to @Mitch Dempsy answer since I don't have enough rep to comment yet.

svn export -r <REV> svn://host/path/to/file/on/repos --force

Adding the --force will overwrite the local copy with the export and then you can do an svn commit to push it to the repository.

Get the difference between the two dates and then get the days from:

int total_days = (EndDate - StartDate).TotalDays

you just add this style in your style.xml file which is in your values folder

<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
</style>

After that set this style to your activity class in your AndroidManifest.xml file

android:theme="@style/AppTheme.NoActionBar"

Edit:- If you are going with programmatic way to hide ActionBar then use below code in your activity onCreate() method.

if(getSupportedActionbar()!=null)    
     this.getSupportedActionBar().hide();

and if you want to hide ActionBar from Fragment then

getActivity().getSupportedActionBar().hide();

AppCompat v7:- Use following theme in your Activities where you don't want actiobBar Theme.AppComat.NoActionBar or Theme.AppCompat.Light.NoActionBar or if you want to hide in whole app then set this theme in your <application... /> in your AndroidManifest.

In Kotlin:

add this line of code in your onCreate() method or you can use above theme.

if (supportActionBar != null)
        supportActionBar?.hide()

i hope this will help you more.

A Stack allows you to stack elements on top of each other, with the last element in the array taking the highest priority. You can use Align, Positioned, or Container to position the children of a stack.

Align

Widgets are moved by setting the alignment with Alignment, which has static properties like topCenter, bottomRight, and so on. Or you can take full control and set Alignment(1.0, -1.0), which takes x,y values ranging from 1.0 to -1.0, with (0,0) being the center of the screen.

  Stack(
      children: [
        Align(
          alignment: Alignment.topCenter,
          child: Container(
              height: 80,
              width: 80, color: Colors.blueAccent
          ),
        ),
        Align(
          alignment: Alignment.center,
          child: Container(
              height: 80,
              width: 80, color: Colors.deepPurple
          ),
        ),
        Container(
          alignment: Alignment.bottomCenter,
          // alignment: Alignment(1.0, -1.0),
          child: Container(
              height: 80,
              width: 80, color: Colors.amber
          ),
        )
      ]
  )

I threw together a small library for this since I do think there are valid use cases for manipulating stylesheets in JS. Reasons being:

• Setting styles that must be calculated or retrieved - for example setting the user's preferred font-size from a cookie.
• Setting behavioural (not aesthetic) styles, especially for UI widget/plugin developers. Tabs, carousels, etc, often require some basic CSS simply to function - shouldn't demand a stylesheet for the core function.
• Better than inline styles since CSS rules apply to all current and future elements, and don't clutter the HTML when viewing in Firebug / Developer Tools.

with pygame:

dy = p1.y - p2.y
dX = p2.x - p1.x

rads = atan2(dy,dx)
degs = degrees(rads)
if degs < 0 :
   degs +=90

it work for me

After making no changes to a production server we began receiving this error. After trying several different things and thinking that perhaps there were DNS issues, restarting IIS fixed the issue (restarting only the site did not fix the issue). It likely won't work for everyone but if we tried that first it would have saved a lot of time.

Take the string Hello and run it through recursively.

So the first call will return:

return reverse(ello) + H

Second

return reverse(llo) + e

Which will eventually return olleH
