Programs & Examples On #Table per hierarchy

I tried everything suggested on whole Stackoverflow. Nothing including -a or -am or anything helped.

If you are the same, do this.

So, the problem is, git thinks some of your subdirectory is sub-project in your root-project. At least, in my case it wasn't like that. It was just regular sub-directory. Not individual project.

Move that regular sub-directory which is not being pushed at some temporary location.

Remove the hidden .git folder from that directory.

cd to the root directory.

git init again.

git add . again.

git commit -m "removed notPushableDirectory temporarily"

git push -f origin master

We will have to force it as the git will see the conflict between remote git and your local structure. Remember, we created this conflict. So, don't worry about forcing it.

Now, it will push that sub-directory as sub-directory and not as sub-module or sub-project inside your root-project.

Use a CASE statement instead of IF.

To do this without any headache:

1. Check out what's the current branch in the gitrepo1 with git status, let's say branch "development".
2. Change directory to the newrepo, then git clone the project from repository.
3. Switch branch in newrepo to the previous one: git checkout development.
4. Syncronize newrepo with the older one, gitrepo1 using rsync, excluding .git folder: rsync -azv --exclude '.git' gitrepo1 newrepo/gitrepo1. You don't have to do this with rsync of course, but it does it so smooth.

The benefit of this approach: you are good to continue exactly where you left off: your older branch, unstaged changes, etc.

It's been a while, but last time I had something similar:

ROLLBACK TRAN

or trying to

COMMIT

what had allready been done free'd everything up so I was able to clear things out and start again.

Try the vim-way:

ex -s +"g/foo/d" -cwq file.txt

I've got a simple method without splitting:

a = "Lorem   Ipsum Darum     Diesrum!"
while True:
    count = a.find("  ")
    if count > 0:
        a = a.replace("  ", " ")
        count = a.find("  ")
        continue
    else:
        break

print(a)

The common method for doing what you're looking to do is to run them side by side, and either proxy requests from apache to node.js based on domain / url, or simply have your node.js content be pulled from the node.js port. This later method works very well for having things like socket.io powered widgets on your site and such.

If you're going to be doing all of your dynamic content generation in node however, you might as well just use node.js as your primary webserver too, it does a very good job at serving both static and dynamic http requests.

See:

http://expressjs.com/

https://github.com/joyent/node/wiki/modules

$('#link1').text("Replacement text");

The .text() method drops the text you pass it into the element content. Unlike using .html(), .text() implicitly ignores any embedded HTML markup, so if you need to embed some inline <span>, <i>, or whatever other similar elements, use .html() instead.

Making Node.js code sync is essential in few aspects such as database. But actual advantage of Node.js lies in async code. As it is single thread non-blocking.

we can sync it using important functionality Fiber() Use await() and defer () we call all methods using await(). then replace the callback functions with defer().

Normal Async code.This uses CallBack functions.

function add (var a, var b, function(err,res){
       console.log(res);
});

 function sub (var res2, var b, function(err,res1){
           console.log(res);
    });

 function div (var res2, var b, function(err,res3){
           console.log(res3);
    });

Sync the above code using Fiber(), await() and defer()

fiber(function(){
     var obj1 = await(function add(var a, var b,defer()));
     var obj2 = await(function sub(var obj1, var b, defer()));
     var obj3 = await(function sub(var obj2, var b, defer()));

});

I hope this will help. Thank You

The problem with Yahoo and Google data is that it violates terms of service if you're using it for commercial use. When your site/app is still small it's not biggie, but as soon as you grow a little you start getting cease and desists from the exchanges. A licensed solution example is FinancialContent: http://www.financialcontent.com/json.php or Xignite

Use -t on ls. e.g:.

ls -tr

or

ls -ltr

UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')
WHERE number like 'KIT%'

• SQLFiddle Demo

or simply this if you are sure that you have no values like this CKIT002

UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')

• SQLFiddle Demo

Here's a sample code:

Exec sp_add_schedule
    @schedule_name = N'SchedulName' 
    @freq_type = 1
    @active_start_time = 08300

Just loop...

foreach(var table in DataSet1.Tables) {
    foreach(var col in table.Columns) {
       ...
    }
    foreach(var row in table.Rows) {
        object[] values = row.ItemArray;
        ...
    }
}

You can not alter constraints ever but you can drop them and then recreate.

Have look on this

ALTER TABLE your_table DROP CONSTRAINT ACTIVEPROG_FKEY1;

and then recreate it with ON DELETE CASCADE like this

ALTER TABLE your_table
add CONSTRAINT ACTIVEPROG_FKEY1 FOREIGN KEY(ActiveProgCode) REFERENCES PROGRAM(ActiveProgCode)
    ON DELETE CASCADE;

hope this help

Here is an example using PREPARE statements. You still can't use ?, but you can use $n notation:

PREPARE foo(integer) AS
    SELECT  *
    FROM    somewhere
    WHERE   something = $1;
EXECUTE foo(5);
DEALLOCATE foo;

Sometimes you want to filter the list based on public/private vars. E.g.

def pub_vars(self):
    """Gives the variable names of our instance we want to expose
    """
    return [k for k in vars(self) if not k.startswith('_')]

Select ColumnB and as two CF formula rules apply:

Green: =AND(B1048576="X",B1="Y")

Red: =AND(B1048576="X",B1="W")

add this to your package.json file

scripts {
"dev": "nodemon --watch '**/*.ts' --exec 'ts-node' index.ts"
}

and to make this work you also need to install ts-node as dev-dependency

yarn add ts-node -D

run yarn dev to start the dev server

Whatever Apple ships as the default gcc in xcode (4.2.1 on 10.6, 4.0.1 before) is well tested (and maintained) by the apple guys and the "standard" to build software with on OS X. Everything else is not, so think twice if you want to develop software, or be gcc/OS X beta tester.

If you want to log a stacktrace without involving an exception just do this:

String message = "";

for(StackTraceElement stackTraceElement : Thread.currentThread().getStackTrace()) {                         
    message = message + System.lineSeparator() + stackTraceElement.toString();
}   
log.warn("Something weird happened. I will print the the complete stacktrace even if we have no exception just to help you find the cause" + message);

I figured out a way using https://github.com/springfox/springfox and https://github.com/RobWin/swagger2markup

Used Swagger 2 to implement documentation.

I think git fetch is what your looking for.

It will pull the changes and objects without committing them to your local repo's index.

They can be merged later with git merge.

Man Page

Edit: Further Explination

Straight from the Git- SVN Crash Course link

Now, how do you get any new changes from a remote repository? You fetch them:

git fetch http://host.xz/path/to/repo.git/ 

At this point they are in your repository and you can examine them using:

git log origin 

You can also diff the changes. You can also use git log HEAD..origin to see just the changes you don't have in your branch. Then if would like to merge them - just do:

git merge origin

Note that if you don't specify a branch to fetch, it will conveniently default to the tracking remote.

Reading the man page is honestly going to give you the best understanding of options and how to use it.

I'm just trying to do this by examples and memory, I don't currently have a box to test out on. You should look at:

git log -p //log with diff

A fetch can be undone with git reset --hard (link) , however all uncommitted changes in your tree will be lost as well as the changes you've fetched.

The following syntax can also be used if the array is not named (just the array is passed to the template):

  <ul id="luke_should_be_here">
  {{this.1.name}}
  </ul>

Got it to work go to the local.properties file under your build.gradle files to find out the PATH to your SDK, from the SDK location go into the platform-tools folder and look and see if you have adb.exe. If not go to http://adbshell.com/downloads and download ADB KITS. Copy the zip folder's contents into the platform-tools folder and re-make your project.

I didn't need to update the PATH in the Extended Controls Settings section on the emulator, I left Use detected ADB location settings on. Hope this makes this faster for you !

In your Controller

public function updtitle() 
{   
    $data = array(
        'table_name' => 'your_table_name_to_update', // pass the real table name
        'id' => $this->input->post('id'),
        'title' => $this->input->post('title')
    );

    $this->load->model('Updmodel'); // load the model first
    if($this->Updmodel->upddata($data)) // call the method from the model
    {
        // update successful
    }
    else
    {
        // update not successful
    }

}

In Your Model

public function upddata($data) {
    extract($data);
    $this->db->where('emp_no', $id);
    $this->db->update($table_name, array('title' => $title));
    return true;
}

The active record query is similar to

"update $table_name set title='$title' where emp_no=$id"

Include the jQuery file first:

 <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
 <script type="text/javascript" src="./javascript.js"></script>
    <script
        src="http://maps.googleapis.com/maps/api/js?key=AIzaSyCJnj2nWoM86eU8Bq2G4lSNz3udIkZT4YY&sensor=false">
    </script>

Doing

select count(j1.job_number), j1.job_number, j1.id, j2.id
from   jobs j1 join jobs j2 on (j1.job_numer = j2.job_number)
where  j1.id != j2.id
group by j1.job_number

will give you the duplicated rows' ids.

You can rename your Conda env by just renaming the env folder. Here is the proof:

You can find your Conda env folder inside of C:\ProgramData\Anaconda3\envs or you can enter conda env list to see the list of conda envs and its location.

First things first ,

they are not always equal

    select 'Hello' from dual where 'Hello  ' like 'Hello';

    select 'Hello' from dual where 'Hello  ' =  'Hello';

when things are not always equal , talking about their performance isn't that relevant.

If you are working on strings and only char variables , then you can talk about performance . But don't use like and "=" as being generally interchangeable .

As you would have seen in many posts ( above and other questions) , in cases when they are equal the performance of like is slower owing to pattern matching (collation)

Avoid using strcat in C code. The cleanest and, most importantly, the safest way is to use snprintf:

char buf[256];
snprintf(buf, sizeof buf, "%s%s%s%s", str1, str2, str3, str4);

Some commenters raised an issue that the number of arguments may not match the format string and the code will still compile, but most compilers already issue a warning if this is the case.

Private Sub YourWebPage_PreRenderComplete(sender As Object, e As EventArgs) Handles Me.PreRenderComplete

     If Not IsPostBack Then
     DropDownList1.Items.Insert(0, "Select")
     End If

End Sub

Another difference between them is the size of the file:

• Mustache.js has 9kb,
• Handlebars.js has 86kb, or 18kb if using precompiled templates.

To see the performance benefits of Handlebars.js we must use precompiled templates.

Try adding the button to the navigationItem of the view controller that is going to be pushed onto this PropertyViewController class you have created.

That is:

MainViewController *vc = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil];
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
[infoButton addTarget:self action:@selector(showInfo) forControlEvents:UIControlEventTouchUpInside];
vc.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:infoButton] autorelease];

PropertyViewController *navController = [[PropertyViewController alloc] initWithRootViewController:vc];

Now, this infoButton that has been created programatically will show up in the navigation bar. The idea is that the navigation controller picks up its display information (title, buttons, etc) from the UIViewController that it is about to display. You don't actually add buttons and such directly to the UINavigationController.

<select name="flowers" size="5" style="height:200px">
 <option value="1">Rose</option>
 <option value="2">Tulip</option>
</select>

This simple solution allows to obtain visually a list of options, but to be able to select only one.

I believe that sorting by the column you want to get the MAX of and then grabbing the first should work. However, if there are multiple objects with the same MAX value, only one will be grabbed:

private void Test()
{
    test v1 = new test();
    v1.Id = 12;

    test v2 = new test();
    v2.Id = 12;

    test v3 = new test();
    v3.Id = 12;

    List<test> arr = new List<test>();
    arr.Add(v1);
    arr.Add(v2);
    arr.Add(v3);

    test max = arr.OrderByDescending(t => t.Id).First();
}

class test
{
    public int Id { get; set; }
}

Kind of an embarrassing occurrence of this error for me, but if it helps the cause...

Make sure you have Ubuntu for desktop, part 1 of this wikihow:

http://www.wikihow.com/Install-Ubuntu-on-VirtualBox

A part I may or may not have skipped, along with part 4 (selecting the Ubuntu ISO as the CD Load)

Nobody's perfect :)

An entity manager can only be injected in classes running inside a transaction. In other words, it can only be injected in a EJB. Other classe must use an EntityManagerFactory to create and destroy an EntityManager.

Since your TestService is not an EJB, the annotation @PersistenceContext is simply ignored. Not only that, in JavaEE 5, it's not possible to inject an EntityManager nor an EntityManagerFactory in a JAX-RS Service. You have to go with a JavaEE 6 server (JBoss 6, Glassfish 3, etc).

Here's an example of injecting an EntityManagerFactory:

package com.test.service;

import java.util.*;
import javax.persistence.*;
import javax.ws.rs.*;

@Path("/service")
public class TestService {

    @PersistenceUnit(unitName = "test")
    private EntityManagerFactory entityManagerFactory;

    @GET
    @Path("/get")
    @Produces("application/json")
    public List get() {
        EntityManager entityManager = entityManagerFactory.createEntityManager();
        try {
            return entityManager.createQuery("from TestEntity").getResultList();
        } finally {
            entityManager.close();
        }
    }
}

The easiest way to go here is to declare your service as a EJB 3.1, assuming you're using a JavaEE 6 server.

Related question: Inject an EJB into JAX-RS (RESTful service)

To read the data line-by-line into a Bash array you can do this:

while read -a row
do
    echo "..${row[0]}..${row[1]}..${row[2]}.."
done < <(echo "SELECT A, B, C FROM table_a" | mysql database -u $user -p $password)

Or into individual variables:

while read a b c
do
    echo "..${a}..${b}..${c}.."
done < <(echo "SELECT A, B, C FROM table_a" | mysql database -u $user -p $password)

None of the about answers works for my case. I got the answer from here, and my SQL is:

INSERT INTO product (id, catalog_id, status_id, name, measure_unit_id, description, create_time)
VALUES (
  (SELECT id FROM (SELECT COALESCE(MAX(id),0)+1 AS id FROM product) AS temp),
  (SELECT id FROM product_catalog WHERE name="AppSys1"),
  (SELECT id FROM product_status WHERE name ="active"),
  "prod_name_x",
  (SELECT id FROM measure_unit WHERE name ="unit"),
  "prod_description_y",
  UNIX_TIMESTAMP(NOW())
)

Alternative approach would be

Controller

use Session;
       
Session::flash('message', "Special message goes here");
return Redirect::back();

View

@if (Session::has('message'))
   <div class="alert alert-info">{{ Session::get('message') }}</div>
@endif

int[] arr = new int[5] {1,2,3,4,5};

You can use Linq for it

String arrTostr = arr.Select(a => a.ToString()).Aggregate((i, j) => i + "," + j);

Try

//*[text()='qwerty'] because . is your current element

I added a "Height" to my ListBox and it added the scrollbar nicely.

You can always use Request.QueryString collection like Web forms, but you can also make MVC handle them and pass them as parameters. This is the suggested way as it's easier and it will validate input data type automatically.

I just had the same problem. I'd say it has nothing to do with the apache.conf.

a2ensite must have changed - line 532 is the line that enforces the .conf suffix:

else {
    $dir    = 'sites';
    $sffx   = '.conf';
    $reload = 'reload';
}

If you change it to:

else {
    $dir    = 'sites';
    #$sffx   = '.conf';
    $sffx   = '';
    $reload = 'reload';
}

...it will work without any suffix.

Of course you wouldn't want to change the a2ensite script, but changing the conf file's suffix is the correct way.

It's probably just a way of enforcing the ".conf"-suffix.

You can use CSS to set the opacity, and than use javascript to apply the styles to a certain element in the DOM.

.opClass {
    opacity:0.4;
    filter:alpha(opacity=40); /* For IE8 and earlier */
}

Than use (for example) jQuery to change the style:

$('#element_id').addClass('opClass');

Or with plain javascript, like this:

document.getElementById("element_id").className = "opClass";

Here is a Github link to a lightweight and very easy to integrate library that enables you to play with borders as you want for any widget you want, simply based on a FrameLayout widget.

Here is a quick sample code for you to see how easy it is, but you will find more information on the link.

<com.khandelwal.library.view.BorderFrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:leftBorderColor="#00F0F0"
            app:leftBorderWidth="10dp"
            app:topBorderColor="#F0F000"
            app:topBorderWidth="15dp"
            app:rightBorderColor="#F000F0"
            app:rightBorderWidth="20dp"
            app:bottomBorderColor="#000000"
            app:bottomBorderWidth="25dp" >
    </com.khandelwal.library.view.BorderFrameLayout>

So, if you don't want borders on bottom, delete the two lines about bottom in this custom widget, and that's done.

And no, I'm neither the author of this library nor one of his friend ;-)

you should use action instead of actionListener:

<h:commandLink id="close" action="#{bean.close}" value="Close" immediate="true" 
                                   />

and in close method you right something like:

public String close() {
   return "index?faces-redirect=true";
}

where index is one of your pages(index.xhtml)

Of course, all this staff should be written in our original page, not in the intermediate. And inside the close() method you can use the parameters to dynamically choose where to redirect.

.slice() isn't always better. In my case, with jQuery 1.7 in Chrome 36, .slice(0, 20) failed with error:

RangeError: Maximum call stack size exceeded

I found that :lt(20) worked without error in this case. I had probably tens of thousands of matching elements.

I use 3 lines to do this job, so consider $s as your "stuff"...

$s=str_replace(chr(10),'',$s);
$s=str_replace(chr(13),'',$s);
$s=str_replace("\r\n"),'',$s);

Please use regex to remove anything before |

example

dsfdf | fdfsfsf
dsdss|gfghhghg
dsdsds |dfdsfsds

Use find and replace in notepad++

find: .+(\|) replace: \1

output

| fdfsfsf
|gfghhghg
|dfdsfsds

ld is trying to find libcrypto.sowhich is not present as seen in your locate output. You can make a copy of the libcrypto.so.0.9.8 and name it as libcrypto.so. Put this is your ld path. ( If you do not have root access then you can put it in a local path and specify the path manually )

Changing the target framework from .NET Framework 4 Client Profile to .NET Framework 4 fixed this problem for me.

So in your example: set the target framework on MyWebProject1 to .NET Framework 4

Solutions until now only deal with lists, and most are copying the list. In my experience a lot of times that isn't possible.

Also, they don't deal with the fact that you can have repeated elements in the list.

The title of your question says "Previous and next values inside a loop", but if you run most answers here inside a loop, you'll end up iterating over the entire list again on each element to find it.

So I've just created a function that. using the itertools module, splits and slices the iterable, and generates tuples with the previous and next elements together. Not exactly what your code does, but it is worth taking a look, because it can probably solve your problem.

from itertools import tee, islice, chain, izip

def previous_and_next(some_iterable):
    prevs, items, nexts = tee(some_iterable, 3)
    prevs = chain([None], prevs)
    nexts = chain(islice(nexts, 1, None), [None])
    return izip(prevs, items, nexts)

Then use it in a loop, and you'll have previous and next items in it:

mylist = ['banana', 'orange', 'apple', 'kiwi', 'tomato']

for previous, item, nxt in previous_and_next(mylist):
    print "Item is now", item, "next is", nxt, "previous is", previous

The results:

Item is now banana next is orange previous is None
Item is now orange next is apple previous is banana
Item is now apple next is kiwi previous is orange
Item is now kiwi next is tomato previous is apple
Item is now tomato next is None previous is kiwi

It'll work with any size list (because it doesn't copy the list), and with any iterable (files, sets, etc). This way you can just iterate over the sequence, and have the previous and next items available inside the loop. No need to search again for the item in the sequence.

A short explanation of the code:

• tee is used to efficiently create 3 independent iterators over the input sequence
• chain links two sequences into one; it's used here to append a single-element sequence [None] to prevs
• islice is used to make a sequence of all elements except the first, then chain is used to append a None to its end
• There are now 3 independent sequences based on some_iterable that look like:
  • prevs: None, A, B, C, D, E
  • items: A, B, C, D, E
  • nexts: B, C, D, E, None
• finally izip is used to change 3 sequences into one sequence of triplets.

Note that izip stops when any input sequence gets exhausted, so the last element of prevs will be ignored, which is correct - there's no such element that the last element would be its prev. We could try to strip off the last elements from prevs but izip's behaviour makes that redundant

Also note that tee, izip, islice and chain come from the itertools module; they operate on their input sequences on-the-fly (lazily), which makes them efficient and doesn't introduce the need of having the whole sequence in memory at once at any time.

In python 3, it will show an error while importing izip,you can use zip instead of izip. No need to import zip, it is predefined in python 3 - source

You actually don't need to pass a body to match_all, it can be done with a GET request to the following URL. This is the simplest form.

http://localhost:9200/foo/_search

You need to call the

$.parseJSON();

For example:

...
success: function(data){
       var json = $.parseJSON(data); // create an object with the key of the array
       alert(json.html); // where html is the key of array that you want, $response['html'] = "<a>something..</a>";
    },
    error: function(data){
       var json = $.parseJSON(data);
       alert(json.error);
    } ...

see this in http://api.jquery.com/jQuery.parseJSON/

if you still have the problem of slashes: search for security.magicquotes.disabling.php or: function.stripslashes.php

Note:

This answer here is for those who try to use $.ajax with the dataType property set to json and even that got the wrong response type. Defining the header('Content-type: application/json'); in the server may correct the problem, but if you are returning text/html or any other type, the $.ajax method should convert it to json. I make a test with older versions of jQuery and only after version 1.4.4 the $.ajax force to convert any content-type to the dataType passed. So if you have this problem, try to update your jQuery version.

Pros and cons between #defines, consts and (what you have forgot) enums, depending on usage:

1. enums:

   • only possible for integer values
   • properly scoped / identifier clash issues handled nicely, particularly in C++11 enum classes where the enumerations for enum class X are disambiguated by the scope X::
   • strongly typed, but to a big-enough signed-or-unsigned int size over which you have no control in C++03 (though you can specify a bit field into which they should be packed if the enum is a member of struct/class/union), while C++11 defaults to int but can be explicitly set by the programmer
   • can't take the address - there isn't one as the enumeration values are effectively substituted inline at the points of usage
   • stronger usage restraints (e.g. incrementing - template <typename T> void f(T t) { cout << ++t; } won't compile, though you can wrap an enum into a class with implicit constructor, casting operator and user-defined operators)
   • each constant's type taken from the enclosing enum, so template <typename T> void f(T) get a distinct instantiation when passed the same numeric value from different enums, all of which are distinct from any actual f(int) instantiation. Each function's object code could be identical (ignoring address offsets), but I wouldn't expect a compiler/linker to eliminate the unnecessary copies, though you could check your compiler/linker if you care.
   • even with typeof/decltype, can't expect numeric_limits to provide useful insight into the set of meaningful values and combinations (indeed, "legal" combinations aren't even notated in the source code, consider enum { A = 1, B = 2 } - is A|B "legal" from a program logic perspective?)
   • the enum's typename may appear in various places in RTTI, compiler messages etc. - possibly useful, possibly obfuscation
   • you can't use an enumeration without the translation unit actually seeing the value, which means enums in library APIs need the values exposed in the header, and make and other timestamp-based recompilation tools will trigger client recompilation when they're changed (bad!)

2. consts:

   • properly scoped / identifier clash issues handled nicely
   • strong, single, user-specified type
     • you might try to "type" a #define ala #define S std::string("abc"), but the constant avoids repeated construction of distinct temporaries at each point of use
   • One Definition Rule complications
   • can take address, create const references to them etc.
   • most similar to a non-const value, which minimises work and impact if switching between the two
   • value can be placed inside the implementation file, allowing a localised recompile and just client links to pick up the change

3. #defines:

   • "global" scope / more prone to conflicting usages, which can produce hard-to-resolve compilation issues and unexpected run-time results rather than sane error messages; mitigating this requires:
     • long, obscure and/or centrally coordinated identifiers, and access to them can't benefit from implicitly matching used/current/Koenig-looked-up namespace, namespace aliases etc.
     • while the trumping best-practice allows template parameter identifiers to be single-character uppercase letters (possibly followed by a number), other use of identifiers without lowercase letters is conventionally reserved for and expected of preprocessor defines (outside the OS and C/C++ library headers). This is important for enterprise scale preprocessor usage to remain manageable. 3rd party libraries can be expected to comply. Observing this implies migration of existing consts or enums to/from defines involves a change in capitalisation, and hence requires edits to client source code rather than a "simple" recompile. (Personally, I capitalise the first letter of enumerations but not consts, so I'd be hit migrating between those two too - maybe time to rethink that.)
   • more compile-time operations possible: string literal concatenation, stringification (taking size thereof), concatenation into identifiers
     • downside is that given #define X "x" and some client usage ala "pre" X "post", if you want or need to make X a runtime-changeable variable rather than a constant you force edits to client code (rather than just recompilation), whereas that transition is easier from a const char* or const std::string given they already force the user to incorporate concatenation operations (e.g. "pre" + X + "post" for string)
   • can't use sizeof directly on a defined numeric literal
   • untyped (GCC doesn't warn if compared to unsigned)
   • some compiler/linker/debugger chains may not present the identifier, so you'll be reduced to looking at "magic numbers" (strings, whatever...)
   • can't take the address
   • the substituted value need not be legal (or discrete) in the context where the #define is created, as it's evaluated at each point of use, so you can reference not-yet-declared objects, depend on "implementation" that needn't be pre-included, create "constants" such as { 1, 2 } that can be used to initialise arrays, or #define MICROSECONDS *1E-6 etc. (definitely not recommending this!)
   • some special things like __FILE__ and __LINE__ can be incorporated into the macro substitution
   • you can test for existence and value in #if statements for conditionally including code (more powerful than a post-preprocessing "if" as the code need not be compilable if not selected by the preprocessor), use #undef-ine, redefine etc.
   • substituted text has to be exposed:
     • in the translation unit it's used by, which means macros in libraries for client use must be in the header, so make and other timestamp-based recompilation tools will trigger client recompilation when they're changed (bad!)
     • or on the command line, where even more care is needed to make sure client code is recompiled (e.g. the Makefile or script supplying the definition should be listed as a dependency)

My personal opinion:

As a general rule, I use consts and consider them the most professional option for general usage (though the others have a simplicity appealing to this old lazy programmer).

Here's another way to think about it. Suppose there were a name() function that returned the name of its argument. Given the following code:

def f(a):
    return a

b = "x"
c = b
d = f(c)

e = [f(b), f(c), f(d)]

What should name(e[2]) return, and why?

There are many formats supported by SQL Server - see the MSDN Books Online on CAST and CONVERT. Most of those formats are dependent on what settings you have - therefore, these settings might work some times - and sometimes not.

The way to solve this is to use the (slightly adapted) ISO-8601 date format that is supported by SQL Server - this format works always - regardless of your SQL Server language and dateformat settings.

The ISO-8601 format is supported by SQL Server comes in two flavors:

• YYYYMMDD for just dates (no time portion); note here: no dashes!, that's very important! YYYY-MM-DD is NOT independent of the dateformat settings in your SQL Server and will NOT work in all situations!

or:

• YYYY-MM-DDTHH:MM:SS for dates and times - note here: this format has dashes (but they can be omitted), and a fixed T as delimiter between the date and time portion of your DATETIME.

This is valid for SQL Server 2000 and newer.

So in your concrete case - use these strings:

insert into table1 values('2012-02-21T18:10:00', '2012-01-01T00:00:00');

and you should be fine (note: you need to use the international 24-hour format rather than 12-hour AM/PM format for this).

Alternatively: if you're on SQL Server 2008 or newer, you could also use the DATETIME2 datatype (instead of plain DATETIME) and your current INSERT would just work without any problems! :-) DATETIME2 is a lot better and a lot less picky on conversions - and it's the recommend date/time data types for SQL Server 2008 or newer anyway.

SELECT
   CAST('02-21-2012 6:10:00 PM' AS DATETIME2),     -- works just fine
   CAST('01-01-2012 12:00:00 AM' AS DATETIME2)   -- works just fine  

Don't ask me why this whole topic is so tricky and somewhat confusing - that's just the way it is. But with the YYYYMMDD format, you should be fine for any version of SQL Server and for any language and dateformat setting in your SQL Server.

This answer applies to using gVim on Windows 10. I cannot guarantee the same results for other operating systems.

Add:

set nobackup
set noswapfile
set noundofile

To your _vimrc file.

Note: This is the direct answer to the question (for Windows 10) and probably not the safest thing to do (read the other answers), but this is the fastest solution in my case.

With a small change, it worked fine for me

$qb=$this->dm->createQueryBuilder('AppBundle:CSSDInstrument')
               ->update()
               ->field('status')->set($status)
               ->field('id')->equals($instrumentId)
               ->getQuery()
               ->execute();

You need to add two jars into the WEB-INF/lib directory or your webapp (or lib directory of the server):

• mail.jar - contains the actual smtp implmentation
• activation.jar - needed by mail.jar

I think atompub REST API is a great example of a restful service. See the snippet below from the atompub spec:

The Entry created and returned by the Collection might not match the Entry POSTed by the client. A server MAY change the values of various elements in the Entry, such as the atom:id, atom:updated, and atom:author values, and MAY choose to remove or add other elements and attributes, or change element content and attribute values.

A list in a flask can be easily jsonify using jsonify like:

from flask import Flask,jsonify
app = Flask(__name__)

tasks = [
    {
        'id':1,
        'task':'this is first task'
    },
    {
        'id':2,
        'task':'this is another task'
    }
]

@app.route('/app-name/api/v0.1/tasks',methods=['GET'])
def get_tasks():
    return jsonify({'tasks':tasks})  #will return the json

if(__name__ == '__main__'):
    app.run(debug = True)

Link to JavaDoc

I believe this will surely help you.

javadoc -d C:/javadoc/test com.mypackage

Try this more succinct code:

Sub LoopOverEachColumn()
    Dim WS As Worksheet
    For Each WS In ThisWorkbook.Worksheets
        ResizeColumns WS
    Next WS
End Sub

Private Sub ResizeColumns(WS As Worksheet)
    Dim StrSize As String
    Dim ColIter As Long
    StrSize = "20.14;9.71;35.86;30.57;23.57;21.43;18.43;23.86;27.43;36.71;30.29;31.14;31;41.14;33.86"
    For ColIter = 1 To 15
        WS.Columns(ColIter).ColumnWidth = Split(StrSize, ";")(ColIter - 1)
    Next ColIter
End Sub

If you want additional columns, just change 1 to 15 to 1 to X where X is the column index of the column you want, and append the column size you want to StrSize.

For example, if you want P:P to have a width of 25, just add ;25 to StrSize and change ColIter... to ColIter = 1 to 16.

Hope this helps.

Example how to run program and write stdout and stderr to file with timestamp:

cmd /c ""C:\Program Files (x86)\program.exe" -param fooo >> "c:\dir space\Log_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt" 2>&1"

Key part is to double quote whole part behind cmd /c and inside it use double quotes as usual. Also note that date is locale dependent, this example works using US locale.

The best solution I've come up with at on the spot (though most likely crude) would be:

String.prototype.getBytes = function() {
    var bytes = [];
    for (var i = 0; i < this.length; i++) {
        var charCode = this.charCodeAt(i);
        var cLen = Math.ceil(Math.log(charCode)/Math.log(256));
        for (var j = 0; j < cLen; j++) {
            bytes.push((charCode << (j*8)) & 0xFF);
        }
    }
    return bytes;
}

Though I notice this question has been here for over a year.

If you don't know which option to enter the params. Just want to keep the default value like on_delete=None before migration:

on_delete=models.CASCADE

This is a code snippet in the old version:

if on_delete is None:
    warnings.warn(
        "on_delete will be a required arg for %s in Django 2.0. Set "
        "it to models.CASCADE on models and in existing migrations "
        "if you want to maintain the current default behavior. "
        "See https://docs.djangoproject.com/en/%s/ref/models/fields/"
        "#django.db.models.ForeignKey.on_delete" % (
            self.__class__.__name__,
            get_docs_version(),
        ),
        RemovedInDjango20Warning, 2)
    on_delete = CASCADE

• On Unix, it's in $HOME/.subversion/auth.

• On Windows, I think it's: %APPDATA%\Subversion\auth.

I used apt-cache depends package to get all required packages in any case if the are already installed on system or not. So it will work always correct.
Because the command apt-cache works different, depending on language, you have to try this command on your system and adapt the command. apt-cache depends yourpackage
On an englisch system you get:

$ apt-cache depends yourpackage
node
  Depends: libax25
  Depends: libc6

On an german system you get: node

  Hängt ab von: libax25
  Hängt ab von: libc6

The englisch version with the term:
"Depends:"
You have to change the term "yourpackage" to your wish twice in this command, take care of this!

$ sudo apt-get --print-uris --yes -d --reinstall install yourpackage $(apt-cache depends yourpackage | grep "  Depends:" |  sed 's/  Depends://' | sed ':a;N;$!ba;s/\n//g') | grep ^\' | cut -d\' -f2 >downloads.list

And the german version with the term:
"Hängt ab von:"
You have to change the term "yourpackage" to your wish twice in this command, take care of this!
This text is used twice in this command, if you want to adapt it to your language take care of this!

$ sudo apt-get --print-uris --yes -d --reinstall install yourpackage $(apt-cache depends yourpackage | grep "Hängt ab von:" |  sed 's/  Hängt ab von://' | sed ':a;N;$!ba;s/\n//g') | grep ^\' | cut -d\' -f2 >downloads.list

You get the list of links in downloads.list
Check the list, go to your folder and run the list:

$ cd yourpathToYourFolder

$ wget --input-file downloads.list

All your required packages are in:

$ ls yourpathToYourFolder

Update @Paul Grimshaw answer, use includes insteed of indexOf for more readable

let found = arr1.some(r=> arr2.indexOf(r) >= 0)
let found = arr1.some(r=> arr2.includes(r))

Yes, you can.

this.formGroup.get('name of you control').value

Use a lookup table, like:

char *table[16] = {"0000", "0001", .... "1111"};

then print each nibble like this

printf("%s%s", table[a / 0x10], table[a % 0x10]);

Surely you can use just one table, but it will be marginally faster and too big.

You're using port 3000 on the client-side. I'd hazard a guess that's the Angular port and not the server port? It should be connecting to the server port.

@Dave an updated snippet from http://www.php.net/manual/en/function.strpos.php#107351

function strposa($haystack, $needles=array(), $offset=0) {
        $chr = array();
        foreach($needles as $needle) {
                $res = strpos($haystack, $needle, $offset);
                if ($res !== false) $chr[$needle] = $res;
        }
        if(empty($chr)) return false;
        return min($chr);
}

How to use:

$string = 'Whis string contains word "cheese" and "tea".';
$array  = array('burger', 'melon', 'cheese', 'milk');

if (strposa($string, $array, 1)) {
    echo 'true';
} else {
    echo 'false';
}

will return true, because of array "cheese".

Update: Improved code with stop when the first of the needles is found:

function strposa($haystack, $needle, $offset=0) {
    if(!is_array($needle)) $needle = array($needle);
    foreach($needle as $query) {
        if(strpos($haystack, $query, $offset) !== false) return true; // stop on first true result
    }
    return false;
}
$string = 'Whis string contains word "cheese" and "tea".';
$array  = array('burger', 'melon', 'cheese', 'milk');
var_dump(strposa($string, $array)); // will return true, since "cheese" has been found

Not an official name per se, but I've heard vertical ellipsis referred to as "snowman" in SAS community.

But from what I understand xs:choice still only allows single element selection. Hence setting the MaxOccurs to unbounded like this should only mean that "any one" of the child elements can appear multiple times. Is this accurate?

No. The choice happens individually for every "repetition" of xs:choice that occurs due to maxOccurs="unbounded". Therefore, the code that you have posted is correct, and will actually do what you want as written.

I know this is old question, but I wanted to do the same. Update a file in zip archive. And none of the above answers really helped me.

Here is what I did. Created temp directory abc. Copied file.zip to abc and extracted the file in that directory. I edited the file I wanted to edit. Then while being in abc, ran the following command

user@host ~/temp/abc $ zip -u file.zip
updating: content/js/ (stored 0%)
updating: content/js/moduleConfig.js (deflated 69%)

-u switch will look for changed/new files and will add to the zip archive.

If you are using Swift:

let controller = self.storyboard!.instantiateViewControllerWithIdentifier("controllerID")
self.navigationController!.pushViewController(controller, animated: true)

If you want to get the form data directly from Http request, without any model bindings or FormCollection you can use this:

[HttpPost] 
public ActionResult SubmitAction() {

    // This will return an string array of all keys in the form.
    // NOTE: you specify the keys in form by the name attributes e.g:
    // <input name="this is the key" value="some value" type="test" />
    var keys = Request.Form.AllKeys;

    // This will return the value for the keys.
    var value1 = Request.Form.Get(keys[0]);
    var value2 = Request.Form.Get(keys[1]);
}

The server at x3.chatforyoursite.com needs to output the following header:

Access-Control-Allow-Origin: http://www.example.com

Where http://www.example.com is your website address. You should check your settings on chatforyoursite.com to see if you can enable this - if not their technical support would probably be the best way to resolve this. However to answer your question, you need the remote site to allow your site to access AJAX responses client side.

In Java its Webelement.getText() . Not sure about python.

Try this

hasName = name ? 'Y' : 'N';

It's fatal. The remote server has sent you a RST packet, which indicates an immediate dropping of the connection, rather than the usual handshake. This bypasses the normal half-closed state transition. I like this description:

"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur.

Here is a quick summary of the order characteristics of the standard Set implementations available in Java:

1. keep the insertion order: LinkedHashSet and CopyOnWriteArraySet (thread-safe)
2. keep the items sorted within the set: TreeSet, EnumSet (specific to enums) and ConcurrentSkipListSet (thread-safe)
3. does not keep the items in any specific order: HashSet (the one you tried)

For your specific case, you can either sort the items first and then use any of 1 or 2 (most likely LinkedHashSet or TreeSet). Or alternatively and more efficiently, you can just add unsorted data to a TreeSet which will take care of the sorting automatically for you.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

As it may happens that the default branch of your submodules are not master (which happens a lot in my case), this is how I automate the full Git submodules upgrades:

git submodule init
git submodule update
git submodule foreach 'git fetch origin; git checkout $(git rev-parse --abbrev-ref HEAD); git reset --hard origin/$(git rev-parse --abbrev-ref HEAD); git submodule update --recursive; git clean -dfx'

Here's a 2020 answer with a Hook:

function useDragging() {
  const [isDragging, setIsDragging] = useState(false);
  const [pos, setPos] = useState({ x: 0, y: 0 });
  const ref = useRef(null);

  function onMouseMove(e) {
    if (!isDragging) return;
    setPos({
      x: e.x - ref.current.offsetWidth / 2,
      y: e.y - ref.current.offsetHeight / 2,
    });
    e.stopPropagation();
    e.preventDefault();
  }

  function onMouseUp(e) {
    setIsDragging(false);
    e.stopPropagation();
    e.preventDefault();
  }

  function onMouseDown(e) {
    if (e.button !== 0) return;
    setIsDragging(true);

    setPos({
      x: e.x - ref.current.offsetWidth / 2,
      y: e.y - ref.current.offsetHeight / 2,
    });

    e.stopPropagation();
    e.preventDefault();
  }

  // When the element mounts, attach an mousedown listener
  useEffect(() => {
    ref.current.addEventListener("mousedown", onMouseDown);

    return () => {
      ref.current.removeEventListener("mousedown", onMouseDown);
    };
  }, [ref.current]);

  // Everytime the isDragging state changes, assign or remove
  // the corresponding mousemove and mouseup handlers
  useEffect(() => {
    if (isDragging) {
      document.addEventListener("mouseup", onMouseUp);
      document.addEventListener("mousemove", onMouseMove);
    } else {
      document.removeEventListener("mouseup", onMouseUp);
      document.removeEventListener("mousemove", onMouseMove);
    }
    return () => {
      document.removeEventListener("mouseup", onMouseUp);
      document.removeEventListener("mousemove", onMouseMove);
    };
  }, [isDragging]);

  return [ref, pos.x, pos.y, isDragging];
}

Then a component that uses the hook:

function Draggable() {
  const [ref, x, y, isDragging] = useDragging();

  return (
    <div
      ref={ref}
      style={{
        position: "absolute",
        width: 50,
        height: 50,
        background: isDragging ? "blue" : "gray",
        left: x,
        top: y,
      }}
    ></div>
  );
}

Your class's constructor method should be called __construct(), not __constructor():

public function __construct(EntityManager $entityManager)
{
    $this->em = $entityManager;
}

This excellent answer to a similar question (that I could not find before, unfortunately) helped me solve the problem.

Copying Content from referenced answer :

SQL Developer will look in the following location in this order for a tnsnames.ora file

$HOME/.tnsnames.ora
$TNS_ADMIN/tnsnames.ora
TNS_ADMIN lookup key in the registry
/etc/tnsnames.ora ( non-windows )
$ORACLE_HOME/network/admin/tnsnames.ora
LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME_KEY
LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME

If your tnsnames.ora file is not getting recognized, use the following procedure:

Define an environmental variable called TNS_ADMIN to point to the folder that contains your tnsnames.ora file.

In Windows, this is done by navigating to Control Panel > System > Advanced system settings > Environment Variables...
In Linux, define the TNS_ADMIN variable in the .profile file in your home directory.

Confirm the os is recognizing this environmental variable

From the Windows command line: echo %TNS_ADMIN%

From linux: echo $TNS_ADMIN

Restart SQL Developer Now in SQL Developer right click on Connections and select New Connection.... Select TNS as connection type in the drop down box. Your entries from tnsnames.ora should now display here.

Exponential is worse than polynomial.

O(n^2) falls into the quadratic category, which is a type of polynomial (the special case of the exponent being equal to 2) and better than exponential.

Exponential is much worse than polynomial. Look at how the functions grow

n    = 10    |     100   |      1000

n^2  = 100   |   10000   |   1000000 

k^n  = k^10  |   k^100   |    k^1000

k^1000 is exceptionally huge unless k is smaller than something like 1.1. Like, something like every particle in the universe would have to do 100 billion billion billion operations per second for trillions of billions of billions of years to get that done.

I didn't calculate it out, but ITS THAT BIG.

l =['abc' , 'cd' , 'xy' , 'ba' , 'dc']
l.sort()
print(l1)

Result

['abc', 'ba', 'cd', 'dc', 'xy']

1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.

2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error¹.

3. first() returns the first record found in the database. If no matching model exist, it returns null.

4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error¹.

5. get() returns a collection of models matching the query.

6. pluck($column) returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists.

7. toArray() converts the model/collection into a simple PHP array.

Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.

Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach loop is ok, put passing it to array_map is not. Similarly, if you type-hint an argument as array, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable typehint, which can be used to accept both arrays and collections.

If you ever want to get a plain array from a collection, call its all() method.

¹ The error thrown by the findOrFail and firstOrFail methods is a ModelNotFoundException. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.

jeues answer helped me nothing :-( after hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

after that everything worked very well, even without any "-extension RANDR" switch.

have you tried doing it without the JSON object and just passed two basicnamevaluepairs? also, it might have something to do with your serversettings

Update: this is a piece of code I use:

InputStream is = null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("lastupdate", lastupdate)); 

try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(connection);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
        Log.d("HTTP", "HTTP: OK");
    } catch (Exception e) {
        Log.e("HTTP", "Error in http connection " + e.toString());
    }

Assuming you have some level of control over the protocol, I'm a big fan of sending heartbeats to verify that a connection is active. It's proven to be the most fail proof method and will often give you the quickest notification when a connection has been broken.

TCP keepalives will work, but what if the remote host is suddenly powered off? TCP can take a long time to timeout. On the other hand, if you have logic in your app that expects a heartbeat reply every x seconds, the first time you don't get them you know the connection no longer works, either by a network or a server issue on the remote side.

See Do I need to heartbeat to keep a TCP connection open? for more discussion.

SHOW CREATE PROCEDURE <name>

Returns the text of a previously defined stored procedure that was created using the CREATE PROCEDURE statement. Swap PROCEDURE for FUNCTION for a stored function.

One-to-many and Many-to-one relationship is talking about the same logical relationship, eg an Owner may have many Homes, but a Home can only have one Owner.

So in this example Owner is the One, and Homes are the Many. Each Home always has an owner_id (eg the Foreign Key) as an extra column.

The difference in implementation between these two, is which table defines the relationship. In One-to-Many, the Owner is where the relationship is defined. Eg, owner1.homes lists all the homes with owner1's owner_id In Many-to-One, the Home is where the relationship is defined. Eg, home1.owner lists owner1's owner_id.

I dont actually know in what instance you would implement the many-to-one arrangement, because it seems a bit redundant as you already know the owner_id. Perhaps its related to cleanness of deletions and changes.

date.toJSON() prints the UTC-Date into a String formatted (So adds the offset with it when converts it to JSON format).

date = new Date();
new Date(date.getTime() - (date.getTimezoneOffset() * 60000)).toJSON();

A corresponding cross for ✓ ✓ would be ✗ ✗ I think (Dingbats).

Finally with the latest release of Android Studio 4 and his new Emulator update 10/23/2019 it become easier. Start your emulator and go to emulator parameters ... > in "Routes" tab you can choose two points on the map from/to and start a new route with an adjustable playback speed that can go to more than 1000km/h!

Use formaction attribute inside the button

PS! It only works if your button type="submit"

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

If you want to use the new current standard, you can do so:

sub.emplace_back ("Math", 70, 0);

or

sub.push_back ({"Math", 70, 0});

These don't require default construction of subject.

thread2 = Thread(target=thread2, args=("Thread-2",))

If the timing were right, the a += 100 operation would be skipped:

Processor executes at T a+100 and gets 104. But it stops, and jumps to next thread Here, At T+1 executes a+1 with old value of a, a == 4. So it computes 5. Jump back (at T+2), thread 1, and write a=104 in memory. Now back at thread 2, time is T+3 and write a=5 in memory. Voila! The next print instruction will print 5 instead of 104.

VERY nasty bug to be reproduced and caught.

I guess this is what you want:

l  = range(100)  
index = 0                       
for i in l:                         
    print i,              
    try:
        print l.pop(index+1),                  
        print l.pop(index+1)
    except:
        pass
    index += 1

It is quite handy to code when the number of item to be popped is a run time decision. But it runs with very a bad efficiency and the code is hard to maintain.

One advantage that the aforementioned copy-webpack-plugin brings that hasn't been explained before is that all the other methods mentioned here still bundle the resources into your bundle files (and require you to "require" or "import" them somewhere). If I just want to move some images around or some template partials, I don't want to clutter up my javascript bundle file with useless references to them, I just want the files emitted in the right place. I haven't found any other way to do this in webpack. Admittedly it's not what webpack originally was designed for, but it's definitely a current use case. (@BreakDS I hope this answers your question - it's only a benefit if you want it)

Set the CSS position: relative; on the box. This causes all absolute positions of objects inside to be relative to the corners of that box. Then set the following CSS on the "Bet 5 days ago" line:

position: absolute;
bottom: 0;
right: 0;

If you need to space the text farther away from the edge, you could change 0 to 2px or similar.

Explicitly Target IE versions without hacks using HTML and CSS

Use this approach if you don't want hacks in your CSS. Add a browser-unique class to the <html> element so you can select based on browser later.

Example

<!doctype html>
<!--[if IE]><![endif]-->
<!--[if lt IE 7 ]> <html lang="en" class="ie6">    <![endif]-->
<!--[if IE 7 ]>    <html lang="en" class="ie7">    <![endif]-->
<!--[if IE 8 ]>    <html lang="en" class="ie8">    <![endif]-->
<!--[if IE 9 ]>    <html lang="en" class="ie9">    <![endif]-->
<!--[if (gt IE 9)|!(IE)]><!--><html lang="en"><!--<![endif]-->
    <head></head>
    <body></body>
</html>

Then in your CSS you can very strictly access your target browser.

Example

.ie6 body { 
    border:1px solid red;
}
.ie7 body { 
    border:1px solid blue;
}

For more information check out http://html5boilerplate.com/

Target IE versions with CSS "Hacks"

More to your point, here are the hacks that let you target IE versions.

Use "\9" to target IE8 and below.
Use "*" to target IE7 and below.
Use "_" to target IE6.

Example:

body { 
border:1px solid red; /* standard */
border:1px solid blue\9; /* IE8 and below */
*border:1px solid orange; /* IE7 and below */
_border:1px solid blue; /* IE6 */
}

Update: Target IE10

IE10 does not recognize the conditional statements so you can use this to apply an "ie10" class to the <html> element

<!doctype html>
    <html lang="en">
    <!--[if !IE]><!--><script>if (/*@cc_on!@*/false) {document.documentElement.className+=' ie10';}</script><!--<![endif]-->
        <head></head>
        <body></body>
</html>

One more thing - TemplateBindings don't allow value converting. They don't allow you to pass a Converter and don't automatically convert int to string for example (which is normal for a Binding).

You do not really need jQuery for such tasks. In the ES6 specification they already have out of the box methods startsWith and endsWith.

var str = "To be, or not to be, that is the question.";
alert(str.startsWith("To be"));         // true
alert(str.startsWith("not to be"));     // false
alert(str.startsWith("not to be", 10)); // true

var str = "To be, or not to be, that is the question.";
alert( str.endsWith("question.") );  // true
alert( str.endsWith("to be") );      // false
alert( str.endsWith("to be", 19) );  // true

Currently available in FF and Chrome. For old browsers you can use their polyfills or substr

I had trouble with a .pfx file with openconnect. Renaming didn't solve the problem. I used keytool to convert it to .p12 and it worked.

keytool -importkeystore -destkeystore new.p12 -deststoretype pkcs12 -srckeystore original.pfx

In my case the password for the new file (new.p12) had to be the same as the password for the .pfx file.

if you are just using the simulator and just upgraded then this solved the issue for me: go to menu->project-edit project setting. find code signing section (you can type 'code' in the quick search) in the code signing identity select 'any sdk' and set the value to 'Don't Code Sign'

URL-encoded payload must be provided on the body parameter of the http.NewRequest(method, urlStr string, body io.Reader) method, as a type that implements io.Reader interface.

Based on the sample code:

package main

import (
    "fmt"
    "net/http"
    "net/url"
    "strconv"
    "strings"
)

func main() {
    apiUrl := "https://api.com"
    resource := "/user/"
    data := url.Values{}
    data.Set("name", "foo")
    data.Set("surname", "bar")

    u, _ := url.ParseRequestURI(apiUrl)
    u.Path = resource
    urlStr := u.String() // "https://api.com/user/"

    client := &http.Client{}
    r, _ := http.NewRequest(http.MethodPost, urlStr, strings.NewReader(data.Encode())) // URL-encoded payload
    r.Header.Add("Authorization", "auth_token=\"XXXXXXX\"")
    r.Header.Add("Content-Type", "application/x-www-form-urlencoded")
    r.Header.Add("Content-Length", strconv.Itoa(len(data.Encode())))

    resp, _ := client.Do(r)
    fmt.Println(resp.Status)
}

resp.Status is 200 OK this way.

What about providing a custom N-Factor authentication mechanism?

Before combining available methods, let's assume we can perform the following:

1) Hard-code inside the Java program

2) Store in a .properties file

3) Ask user to type password from command line

4) Ask user to type password from a form

5) Ask user to load a password-file from command line or a form

6) Provide the password through network

7) many alternatives (eg Draw A Secret, Fingerprint, IP-specific, bla bla bla)

1st option: We could make things more complicated for an attacker by using obfuscation, but this is not considered a good countermeasure. A good coder can easily understand how it works if he/she can access the file. We could even export a per-user binary (or just the obfuscation part or key-part), so an attacker must have access to this user-specific file, not another distro. Again, we should find a way to change passwords, eg by recompiling or using reflection to on-the-fly change class behavior.

2nd option: We can store the password in the .properties file in an encrypted format, so it's not directly visible from an attacker (just like jasypt does). If we need a password manager we'll need a master password too which again should be stored somewhere - inside a .class file, the keystore, kernel, another file or even in memory - all have their pros and cons.
But, now users will just edit the .properties file for password change.

3rd option: type the password when running from command line e.g. java -jar /myprogram.jar -p sdflhjkiweHIUHIU8976hyd.

This doesn't require the password to be stored and will stay in memory. However, history commands and OS logs, may be your worst enemy here. To change passwords on-the-fly, you will need to implement some methods (eg listen for console inputs, RMI, sockets, REST bla bla bla), but the password will always stay in memory.

One can even temporarily decrypt it only when required -> then delete the decrypted, but always keep the encrypted password in memory. Unfortunately, the aforementioned method does not increase security against unauthorized in-memory access, because the person who achieves that, will probably have access to the algorithm, salt and any other secrets being used.

4th option: provide the password from a custom form, rather than the command line. This will circumvent the problem of logging exposure.

5th option: provide a file as a password stored previously on a another medium -> then hard delete file. This will again circumvent the problem of logging exposure, plus no typing is required that could be shoulder-surfing stolen. When a change is required, provide another file, then delete again.

6th option: again to avoid shoulder-surfing, one can implement an RMI method call, to provide the password (through an encrypted channel) from another device, eg via a mobile phone. However, you now need to protect your network channel and access to the other device.

I would choose a combination of the above methods to achieve maximum security so one would have to access the .class files, the property file, logs, network channel, shoulder surfing, man in the middle, other files bla bla bla. This can be easily implemented using a XOR operation between all sub_passwords to produce the actual password.

We can't be protected from unauthorized in-memory access though, this can only be achieved by using some access-restricted hardware (eg smartcards, HSMs, SGX), where everything is computed into them, without anyone, even the legitimate owner being able to access decryption keys or algorithms. Again, one can steal this hardware too, there are reported side-channel attacks that may help attackers in key extraction and in some cases you need to trust another party (eg with SGX you trust Intel). Of course, situation may worsen when secure-enclave cloning (de-assembling) will be possible, but I guess this will take some years to be practical.

Also, one may consider a key sharing solution where the full key is split between different servers. However, upon reconstruction, the full key can be stolen. The only way to mitigate the aforementioned issue is by secure multiparty computation.

We should always keep in mind that whatever the input method, we need to ensure we are not vulnerable from network sniffing (MITM attacks) and/or key-loggers.

The problem:

java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer

indicates that you try to use the Jersey 2.x servlet, but you are supplying the Jersey 1.x libs.

For Jersey 1.x you have to do it like this:

<servlet>
  <servlet-name>Jersey REST Service</servlet-name>
<servlet-class>
  com.sun.jersey.spi.container.servlet.ServletContainer
</servlet-class>
  <init-param>
    <param-name>com.sun.jersey.config.property.packages</param-name>
    <param-value>sample.hello.resources</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>Jersey REST Service</servlet-name>
  <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

For more information check the Jersey 1.x documentation.

If you instead want to use Jersey 2.x then you'll have to supply the Jersey 2.x libs. In a maven based project you can use the following:

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.xx</version>
</dependency>
<!-- if you are using Jersey client specific features without the server side -->
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.xx</version>
</dependency>

For Jersey 2.x you don't need to setup anything in your web.xml, it is sufficient to supply a class similar to this:

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("rest")
public class ApplicationConfig extends Application {

}

For more information, check the Jersey documentation.

The most straight-forward approach is to do a second if-test but with the condition inverted. This technique is shorter, easier on the eyes, and easier to get right than a choose-when-otherwise nested block:

<xsl:variable name="CreatedDate" select="@createDate"/>
     <xsl:variable name="IDAppendedDate" select="2012-01-01" />
     <b>date: <xsl:value-of select="$CreatedDate"/></b> 
     <xsl:if test="$CreatedDate &gt; $IDAppendedDate">
        <h2> mooooooooooooo </h2>
     </xsl:if>
     <xsl:if test="$CreatedDate &lt;= $IDAppendedDate">
        <h2> dooooooooooooo </h2>
     </xsl:if>

You can use git show with a path from the root of the repository (./ or ../ for relative pathing):

$ git show REVISION:path/to/file

Replace REVISION with your actual revision (could be a Git commit SHA, a tag name, a branch name, a relative commit name, or any other way of identifying a commit in Git)

For example, to view the version of file <repository-root>/src/main.c from 4 commits ago, use:

$ git show HEAD~4:src/main.c

Git for Windows requires forward slashes even in paths relative to the current directory. For more information, check out the man page for git-show.

So I had a problem I needed solved. I had an array object with values. One of those values I needed to update if the value == X.I needed X value to be updated to the Y value. Looking over examples here none of them worked for what I needed or wanted. I finally figured out a simple solution to the problem and was actually surprised it worked. Now normally I like to put the full code solution into these answers but due to its complexity I wont do that here. If anyone finds they cant make this solution work or need more code let me know and I will attempt to update this at some later date to help. For the most part if the array object has named values this solution should work.

To increase the memory or CPU count when using Vagrant 2, add this to your Vagrantfile

Vagrant.configure("2") do |config|

    config.vm.provider "virtualbox" do |v|
        v.memory = 1024
        v.cpus = 2

Try this:

var i, j;

for (i = 0; i < cubes.length; i++) {
    for (j = 0; j < cubes[i].length; j++) {
       do whatever with cubes[i][j];
    }
}

The accepted answer correctly describes how the list should be declared and is highly recommended for most scenarios.

But I came across a different scenario, which also covers the question asked. What if you have to use an existing object list, like ViewData["htmlAttributes"] in MVC? How can you access its properties (they are usually created via new { @style="width: 100px", ... })?

For this slightly different scenario I want to share with you what I found out. In the solutions below, I am assuming the following declaration for nodes:

List<object> nodes = new List<object>();

nodes.Add(
new
{
    Checked = false,
    depth = 1,
    id = "div_1" 
});

1. Solution with dynamic

In C# 4.0 and higher versions, you can simply cast to dynamic and write:

if (nodes.Any(n => ((dynamic)n).Checked == false))
    Console.WriteLine("found a  not checked  element!");

Note: This is using late binding, which means it will recognize only at runtime if the object doesn't have a Checked property and throws a RuntimeBinderException in this case - so if you try to use a non-existing Checked2 property you would get the following message at runtime: "'<>f__AnonymousType0<bool,int,string>' does not contain a definition for 'Checked2'".

2. Solution with reflection

The solution with reflection works both with old and new C# compiler versions. For old C# versions please regard the hint at the end of this answer.

Background

As a starting point, I found a good answer here. The idea is to convert the anonymous data type into a dictionary by using reflection. The dictionary makes it easy to access the properties, since their names are stored as keys (you can access them like myDict["myProperty"]).

Inspired by the code in the link above, I created an extension class providing GetProp, UnanonymizeProperties and UnanonymizeListItems as extension methods, which simplify access to anonymous properties. With this class you can simply do the query as follows:

if (nodes.UnanonymizeListItems().Any(n => (bool)n["Checked"] == false))
{
    Console.WriteLine("found a  not checked  element!");
}

or you can use the expression nodes.UnanonymizeListItems(x => (bool)x["Checked"] == false).Any() as if condition, which filters implicitly and then checks if there are any elements returned.

To get the first object containing "Checked" property and return its property "depth", you can use:

var depth = nodes.UnanonymizeListItems()
             ?.FirstOrDefault(n => n.Contains("Checked")).GetProp("depth");

or shorter: nodes.UnanonymizeListItems()?.FirstOrDefault(n => n.Contains("Checked"))?["depth"];

Note: If you have a list of objects which don't necessarily contain all properties (for example, some do not contain the "Checked" property), and you still want to build up a query based on "Checked" values, you can do this:

if (nodes.UnanonymizeListItems(x => { var y = ((bool?)x.GetProp("Checked", true)); 
                                      return y.HasValue && y.Value == false;}).Any())
{
    Console.WriteLine("found a  not checked   element!");
}

This prevents, that a KeyNotFoundException occurs if the "Checked" property does not exist.

The class below contains the following extension methods:

• UnanonymizeProperties: Is used to de-anonymize the properties contained in an object. This method uses reflection. It converts the object into a dictionary containing the properties and its values.
• UnanonymizeListItems: Is used to convert a list of objects into a list of dictionaries containing the properties. It may optionally contain a lambda expression to filter beforehand.
• GetProp: Is used to return a single value matching the given property name. Allows to treat not-existing properties as null values (true) rather than as KeyNotFoundException (false)

For the examples above, all that is required is that you add the extension class below:

public static class AnonymousTypeExtensions
{
    // makes properties of object accessible 
    public static IDictionary UnanonymizeProperties(this object obj)
    {
        Type type = obj?.GetType();
        var properties = type?.GetProperties()
               ?.Select(n => n.Name)
               ?.ToDictionary(k => k, k => type.GetProperty(k).GetValue(obj, null));
        return properties;
    }
    
    // converts object list into list of properties that meet the filterCriteria
    public static List<IDictionary> UnanonymizeListItems(this List<object> objectList, 
                    Func<IDictionary<string, object>, bool> filterCriteria=default)
    {
        var accessibleList = new List<IDictionary>();
        foreach (object obj in objectList)
        {
            var props = obj.UnanonymizeProperties();
            if (filterCriteria == default
               || filterCriteria((IDictionary<string, object>)props) == true)
            { accessibleList.Add(props); }
        }
        return accessibleList;
    }

    // returns specific property, i.e. obj.GetProp(propertyName)
    // requires prior usage of AccessListItems and selection of one element, because
    // object needs to be a IDictionary<string, object>
    public static object GetProp(this object obj, string propertyName, 
                                 bool treatNotFoundAsNull = false)
    {
        try 
        {
            return ((System.Collections.Generic.IDictionary<string, object>)obj)
                   ?[propertyName];
        }
        catch (KeyNotFoundException)
        {
            if (treatNotFoundAsNull) return default(object); else throw;
        }
    }
}

Hint: The code above is using the null-conditional operators, available since C# version 6.0 - if you're working with older C# compilers (e.g. C# 3.0), simply replace ?. by . and ?[ by [ everywhere (and do the null-handling traditionally by using if statements or catch NullReferenceExceptions), e.g.

var depth = nodes.UnanonymizeListItems()
            .FirstOrDefault(n => n.Contains("Checked"))["depth"];

As you can see, the null-handling without the null-conditional operators would be cumbersome here, because everywhere you removed them you have to add a null check - or use catch statements where it is not so easy to find the root cause of the exception resulting in much more - and hard to read - code.

If you're not forced to use an older C# compiler, keep it as is, because using null-conditionals makes null handling much easier.

Note: Like the other solution with dynamic, this solution is also using late binding, but in this case you're not getting an exception - it will simply not find the element if you're referring to a non-existing property, as long as you keep the null-conditional operators.

What might be useful for some applications is that the property is referred to via a string in solution 2, hence it can be parameterized.

Check in the folder structure of the project the files within the /gradle/wrapper/ The gradle-wrapper.jar version should be the one specified in the gradle-wrapper.properties

textAlignVertical: "center"

is the real magic.

Take a look at the Dictionary class in System::Collections::Generic.

Dictionary<myComplex, int> myMap = new Dictionary<myComplex, int>();

I use a very simple but efficient technique in my app.js ( my entry point ) I define a variable like

let authUser = {};

Then I assign to it from my route page ( like after successful login )

authUser = matchedUser

It May be not the best approach but it fits my needs.

Adding further...

Every process has same virtual address space (If randomization of virtual address is stopped by using a flag in linux OS) (For more details Disable and re-enable address space layout randomization only for myself)

So if its one exe with no shared linking (Hypothetical scenario), then we can always give same virtual address to same asm instruction without any harm.

But when we want to link shared object to the exe, then we are not sure of the start address assigned to shared object as it will depend upon the order the shared objects were linked.That being said, asm instruction inside .so will always have different virtual address depending upon the process its linking to.

So one process can give start address to .so as 0x45678910 in its own virtual space and other process at the same time can give start address of 0x12131415 and if they do not use relative addressing, .so will not work at all.

So they always have to use the relative addressing mode and hence fpic option.

1) Nowadays, pretty much never. If it's a good idea to inline a function, the compiler will do it without your help.

2) Always. See #1.

Useful link here: Access Tomcat Manager App from different host

From Tomcat version 8 onward's, manager/html url won't be accessible to anyone except localhost.

In order to access /manager/html url, you need to do below change in context.xml of manager app. 1. Go to /apache-tomcat-8.5.23/webapps/manager/META-INF location, then edit context.xml

<Context antiResourceLocking="false" privileged="true" >
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="^.*$" />
 ......
</Context>

2. Restart the server.

The :query_string_normalizer option is also available, which will override the default normalizer HashConversions.to_params(query)

query_string_normalizer: ->(query){query.to_json}

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

This should help you start your mongod server with custom path and port.

You can also use astyle. I found it quite useful and it has several options too:

Tab and Bracket Options:
   If  no  indentation  option is set, the default option of 4 spaces will be used. Equivalent to -s4 --indent=spaces=4.  If no brackets option is set, the
   brackets will not be changed.

   --indent=spaces, --indent=spaces=#, -s, -s#
          Indent using # spaces per indent. Between 1 to 20.  Not specifying # will result in a default of 4 spaces per indent.

   --indent=tab, --indent=tab=#, -t, -t#
          Indent using tab characters, assuming that each tab is # spaces long.  Between 1 and 20. Not specifying # will result in a default assumption  of
          4 spaces per tab.`

This can be the message you receive even when custom errors is turned off in web.config file. It can mean you have run out of free space on the drive that hosts the application. Clean your log files if you have no other space to gain on the drive.

This works:

int pixels = (int)((dp) * Resources.System.DisplayMetrics.Density + 0.5f);

I had remaining private keys from certificates I had revoked, certificates were gone but not the private keys. Deleting them solved the problem.

To find them:

1. Open Keychain access
2. Click "Keys" under category on the side left menu
3. Look for iOS Developer: ..." keys that do not have a certificate tied to them
4. I deleted them and problem went away

The highlighted key in the picture is a sample private key without a certificate.

AssemblyVersion pretty much stays internal to .NET, while AssemblyFileVersion is what Windows sees. If you go to the properties of an assembly sitting in a directory and switch to the version tab, the AssemblyFileVersion is what you'll see up top. If you sort files by version, this is what's used by Explorer.

The AssemblyInformationalVersion maps to the "Product Version" and is meant to be purely "human-used".

AssemblyVersion is certainly the most important, but I wouldn't skip AssemblyFileVersion, either. If you don't provide AssemblyInformationalVersion, the compiler adds it for you by stripping off the "revision" piece of your version number and leaving the major.minor.build.

You have to use parseInt() to convert

For eg.

  var z = parseInt(x) + parseInt(y);

use parseFloat() if you want to handle float value.

Try docker rmi node. That should work.

Seeing all created containers is as simple as docker ps -a.

To remove all existing containers (not images!) run docker rm $(docker ps -aq)

Looking at the AndroidManifest.xml (link), on line 9:

<activity android:screenOrientation="landscape" android:configChanges="orientation|keyboardHidden" android:name="VncCanvasActivity">

This line specifies the screenOrientation as landscape, but author goes further in overriding any screen orientation changes with configChanges="orientation|keyboardHidden". This points to a overridden function in VncCanvasActivity.java.

If you look at VncCanvasActivity, on line 109 is the overrided function:

@Override
public void onConfigurationChanged(Configuration newConfig) {
  // ignore orientation/keyboard change
  super.onConfigurationChanged(newConfig);
}

The author specifically put a comment to ignore any keyboard or orientation changes.

If you want to change this, you can go back to the AndroidManifest.xml file shown above, and change the line to:

<activity android:screenOrientation="sensor" android:name="VncCanvasActivity">

This should change the program to switch from portrait to landscape when the user rotates the device.

This may work, but might mess up how the GUI looks, depending on how the layout were created. You will have to account for that. Also, depending on how the activities are coded, you may notice that when screen orientation is changed, the values that were filled into any input boxes disappear. This also may have to be handled.

In simple term,

• "" is an empty String

• null is an empty String Variable.

Very simple answer for this problem that seems to catch a lot of people:

<img src="url-to-image">
<p>Nullam id dolor id nibh ultricies vehicula ut id elit.</p>

    img {
        float: left;
    }
    p {
        overflow: hidden;
    }

See example: http://jsfiddle.net/vandigroup/upKGe/132/

I think the answer is here (possibly duplicate):

How to test if a file is a directory in a batch script?

IF EXIST %VAR%\NUL ECHO It's a directory

Replace %VAR% with your directory. Please read the original answer because includes details about handling white spaces in the folder name.

As foxidrive said, this might not be reliable on NT class windows. It works for me, but I know it has some limitations (which you can find in the referenced question)

if exist "c:\folder\" echo folder exists 

should be enough for modern windows.

Instead of relying only on <c:out />, an antixss library should also be used, which will not only encode but also sanitize malicious script in input. One of the best library available is OWASP Antisamy, it's highly flexible and can be configured(using xml policy files) as per requirement.

For e.g. if an application supports only text input then most generic policy file provided by OWASP can be used which sanitizes and removes most of the html tags. Similarly if application support html editors(such as tinymce) which need all kind of html tags, a more flexible policy can be use such as ebay policy file

This is something I need all the time so I created a bash function for it. It's based on glenn jackman's answer.

Definition

Add this to your .bash_profile etc.

function regex { gawk 'match($0,/'$1'/, ary) {print ary['${2:-'0'}']}'; }

Usage

Capture regex for each line in file

$ cat filename | regex '.*'

Capture 1st regex capture group for each line in file

$ cat filename | regex '(.*)' 1

This way you check if the string is not null and not empty, also considering the empty spaces:

boolean isEmpty = str == null || str.trim().length() == 0;
if (isEmpty) {
    // handle the validation
}

This works for me. It should be in your onOptionsItemSelected(MenuItem item) method item.setIcon(R.drawable.your_icon);

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

Modal Window using ExtJS approach.

In Main Window

<html>
<link rel="stylesheet" href="ext.css" type="text/css">
<head>    
<script type="text/javascript" src="ext-all.js"></script>

function openModalDialog() {
    Ext.onReady(function() {
        Ext.create('Ext.window.Window', {
        title: 'Hello',
        height: Ext.getBody().getViewSize().height*0.8,
        width: Ext.getBody().getViewSize().width*0.8,
        minWidth:'730',
        minHeight:'450',
        layout: 'fit',
        itemId : 'popUpWin',        
        modal:true,
        shadow:false,
        resizable:true,
        constrainHeader:true,
        items: [{
            xtype: 'box',
            autoEl: {
                     tag: 'iframe',
                     src: '2.html',
                     frameBorder:'0'
            }
        }]
        }).show();
  });
}
function closeExtWin(isSubmit) {
     Ext.ComponentQuery.query('#popUpWin')[0].close();
     if (isSubmit) {
          document.forms[0].userAction.value = "refresh";
          document.forms[0].submit();
    }
}
</head>
<body>
   <form action="abc.jsp">
   <a href="javascript:openModalDialog()"> Click to open dialog </a>
   </form>
</body>
</html>

In popupWindow 2.html

<html>
<head>
<script type="text\javascript">
function doSubmit(action) {
     if (action == 'save') {
         window.parent.closeExtWin(true);
     } else {
         window.parent.closeExtWin(false);
     }   
}
</script>
</head>
<body>
    <a href="javascript:doSubmit('save');" title="Save">Save</a>
    <a href="javascript:doSubmit('cancel');" title="Cancel">Cancel</a>
</body>
</html>

There are two options here.

1. a hidden field within the form, or
2. Add it to the route values parameter in the begin form method.

Edit

@Html.Hidden("clubid", ViewBag.Club.id)

or

 @using(Html.BeginForm("action", "controller",
                       new { clubid = @Viewbag.Club.id }, FormMethod.Post, null)

You should use

<div class="row fluid-img">
  <img class="col-lg-12 col-xs-12" src="src.png">
</div>

.fluid-img {
    margin: 60px auto;
}

@media( min-width: 768px ){
        .fluid-img {
            max-width: 768px;
        }
}
@media screen and (min-width: 768px) {
        .fluid-img {
            padding-left: 0;
            padding-right: 0;
        }
}

To summarize the information found after the link: The JVM allocates the amount specified by -Xms but the OS usually does not allocate real pages until they are needed. So the JVM allocates virtual memory as specified by Xms but only allocates physical memory as is needed.

You can see this by using Process Explorer by Sysinternals instead of task manager on windows.

So there is a real difference between using -Xms64M and -Xms512M. But I think the most important difference is the one you already pointed out: the garbage collector will run more often if you really need the 512MB but only started with 64MB.

If you really want a String.EMPTY constant, you can create an utility static final class named "Constants" (for example) in your project. This class will maintain your constants, including the empty String...

In the same idea, you can create ZERO, ONE int constants... that don't exist in the Integer class, but like I commented, it would be a pain to write and to read :

for(int i=Constants.ZERO; ...) {
    if(myArray.length > Constants.ONE) {
        System.out.println("More than one element");
    }
}

Etc.

Yes, Java bytecode (and source code) is platform independent, assuming you use platform independent libraries. 32 vs. 64 bit shouldn't matter.

You can call a controller function with AJAX on your view. In this case, I'm using the jQuery library to make the call.

<script type="text/javascript">
    $.ajax({
            url: "<?=site_url("controller/function")?>",
            type: "post", // To protect sensitive data
            data: {
               ajax:true,
               variableX: "string",
               variableY: 25
               //and any other variables you want to pass via POST
                   },
            success:function(response){
            // Handle the response object
            }
        });
</script>

This way you can create portions of code (modules) and reload them the AJAX method in a HTML container.

This is a good example where you want to get count of Pincode which stored in the last of address field

SELECT DISTINCT
    RIGHT (address, 6),
    count(*) AS count
FROM
    datafile
WHERE
    address IS NOT NULL
GROUP BY
    RIGHT (address, 6)

I know this question is almost 3 years old, but I asked myself the very same question and did not found any ready made solution. So, I created a custom git command shell script my self.

Here it goes, the git-ffwd-update script does the following...

1. it issues a git remote update to fetch the lates revs
2. then uses git remote show to get a list of local branches that track a remote branch (e.g. branches that can be used with git pull)
3. then it checks with git rev-list --count <REMOTE_BRANCH>..<LOCAL_BRANCH> how many commit the local branch is behind the remote (and ahead vice versa)
4. if the local branch is 1 or more commits ahead, it can NOT be fast-forwarded and needs to be merged or rebased by hand
5. if the local branch is 0 commits ahead and 1 or more commits behind, it can be fast-forwarded by git branch -f <LOCAL_BRANCH> -t <REMOTE_BRANCH>

the script can be called like:

$ git ffwd-update
Fetching origin
 branch bigcouch was 10 commit(s) behind of origin/bigcouch. resetting local branch to remote
 branch develop was 3 commit(s) behind of origin/develop. resetting local branch to remote
 branch master is 6 commit(s) behind and 1 commit(s) ahead of origin/master. could not be fast-forwarded

The full script, should be saved as git-ffwd-update and needs to be on the PATH.

#!/bin/bash

main() {
  REMOTES="$@";
  if [ -z "$REMOTES" ]; then
    REMOTES=$(git remote);
  fi
  REMOTES=$(echo "$REMOTES" | xargs -n1 echo)
  CLB=$(git rev-parse --abbrev-ref HEAD);
  echo "$REMOTES" | while read REMOTE; do
    git remote update $REMOTE
    git remote show $REMOTE -n \
    | awk '/merges with remote/{print $5" "$1}' \
    | while read RB LB; do
      ARB="refs/remotes/$REMOTE/$RB";
      ALB="refs/heads/$LB";
      NBEHIND=$(( $(git rev-list --count $ALB..$ARB 2>/dev/null) +0));
      NAHEAD=$(( $(git rev-list --count $ARB..$ALB 2>/dev/null) +0));
      if [ "$NBEHIND" -gt 0 ]; then
        if [ "$NAHEAD" -gt 0 ]; then
          echo " branch $LB is $NBEHIND commit(s) behind and $NAHEAD commit(s) ahead of $REMOTE/$RB. could not be fast-forwarded";
        elif [ "$LB" = "$CLB" ]; then
          echo " branch $LB was $NBEHIND commit(s) behind of $REMOTE/$RB. fast-forward merge";
          git merge -q $ARB;
        else
          echo " branch $LB was $NBEHIND commit(s) behind of $REMOTE/$RB. resetting local branch to remote";
          git branch -f $LB -t $ARB >/dev/null;
        fi
      fi
    done
  done
}

Basic rule says that :

For Entities with generated identifier :

save() : It returns an entity's identifier immediately in addition to making the object persistent. So an insert query is fired immediately.

persist() : It returns the persistent object. It does not have any compulsion of returning the identifier immediately so it does not guarantee that insert will be fired immediately. It may fire an insert immediately but it is not guaranteed. In some cases, the query may be fired immediately while in others it may be fired at session flush time.

For Entities with assigned identifier :

save(): It returns an entity's identifier immediately. Since the identifier is already assigned to entity before calling save, so insert is not fired immediately. It is fired at session flush time.

persist() : same as save. It also fire insert at flush time.

Suppose we have an entity which uses a generated identifier as follows :

@Entity
@Table(name="USER_DETAILS")
public class UserDetails {
    @Id
    @Column(name = "USER_ID")
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int userId;

    @Column(name = "USER_NAME")
    private String userName;

    public int getUserId() {
        return userId;
    }
    public void setUserId(int userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
}

save() :

    Session session = sessionFactory.openSession();
    session.beginTransaction();
    UserDetails user = new UserDetails();
    user.setUserName("Gaurav");
    session.save(user); // Query is fired immediately as this statement is executed.
    session.getTransaction().commit();
    session.close();

persist() :

    Session session = sessionFactory.openSession();
    session.beginTransaction();
    UserDetails user = new UserDetails();
    user.setUserName("Gaurav");
    session.persist(user); // Query is not guaranteed to be fired immediately. It may get fired here.
    session.getTransaction().commit(); // If it not executed in last statement then It is fired here.
    session.close();

Now suppose we have the same entity defined as follows without the id field having generated annotation i.e. ID will be assigned manually.

@Entity
@Table(name="USER_DETAILS")
public class UserDetails {
    @Id
    @Column(name = "USER_ID")
    private int userId;

    @Column(name = "USER_NAME")
    private String userName;

    public int getUserId() {
        return userId;
    }
    public void setUserId(int userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
}

for save() :

Session session = sessionFactory.openSession();
session.beginTransaction();
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("Gaurav");
session.save(user); // Query is not fired here since id for object being referred by user is already available. No query need to be fired to find it. Data for user now available in first level cache but not in db.
session.getTransaction().commit();// Query will be fired at this point and data for user will now also be available in DB
session.close();

for persist() :

Session session = sessionFactory.openSession();
session.beginTransaction();
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("Gaurav");
session.persist(user); // Query is not fired here.Object is made persistent. Data for user now available in first level cache but not in db.
session.getTransaction().commit();// Query will be fired at this point and data for user will now also be available in DB
session.close();

The above cases were true when the save or persist were called from within a transaction.

The other points of difference between save and persist are :

1. save() can be called outside a transaction. If assigned identifier is used then since id is already available, so no insert query is immediately fired. The query is only fired when the session is flushed.

2. If generated identifier is used , then since id need to generated, insert is immediately fired. But it only saves the primary entity. If the entity has some cascaded entities then those will not be saved in db at this point. They will be saved when the session is flushed.

3. If persist() is outside a transaction then insert is fired only when session is flushed no matter what kind of identifier (generated or assigned) is used.

4. If save is called over a persistent object, then the entity is saved using update query.

someList.First(); // exception if collection is empty.
someList.FirstOrDefault(); // first item or default(Type)

Which one to use? It should be decided by the business logic, and not the fear of exception/programm failure.

For instance, If business logic says that we can not have zero transactions on any working day (Just assume). Then you should not try to handle this scenario with some smart programming. I will always use First() over such collection, and let the program fail if something else screwed up the business logic.

Code:

var transactionsOnWorkingDay = GetTransactionOnLatestWorkingDay();
var justNeedOneToProcess = transactionsOnWorkingDay.First(): //Not FirstOrDefault()

I would like to see others comments over this.

Task are being executed on the ThreadPool (at least, if you are using the default factory), so aborting the thread cannot affect the tasks. For aborting tasks, see Task Cancellation on msdn.

days, hours, minutes = td.days, td.seconds // 3600, td.seconds // 60 % 60

As for DST, I think the best thing is to convert both datetime objects to seconds. This way the system calculates DST for you.

>>> m13 = datetime(2010, 3, 13, 8, 0, 0)  # 2010 March 13 8:00 AM
>>> m14 = datetime(2010, 3, 14, 8, 0, 0)  # DST starts on this day, in my time zone
>>> mktime(m14.timetuple()) - mktime(m13.timetuple())     # difference in seconds
82800.0
>>> _/3600                                                # convert to hours
23.0

If you change your time column into row names, then you can use as.data.frame(as.table(mat)) for simple cases like this.

Example:

data <- c(0.1, 0.2, 0.3, 0.3, 0.4, 0.5)
dimnames <- list(time=c(0, 0.5, 1), name=c("C_0", "C_1"))
mat <- matrix(data, ncol=2, nrow=3, dimnames=dimnames)
as.data.frame(as.table(mat))
  time name Freq
1    0  C_0  0.1
2  0.5  C_0  0.2
3    1  C_0  0.3
4    0  C_1  0.3
5  0.5  C_1  0.4
6    1  C_1  0.5

In this case time and name are both factors. You may want to convert time back to numeric, or it may not matter.

Using the query parameter won't work, Google will try to approximate the location.

The location I want : http://maps.google.com/maps?ll=43.7920533400153,6.37761393942265

The approximate location (west of the actual location) : http://maps.google.com/?q=43.7920533400153,6.37761393942265

JPA is a specification to standardize ORM-APIs. Hibernate is a vendor of a JPA implementation. So if you use JPA with hibernate, you can use the standard JPA API, hibernate will be under the hood, offering some more non standard functions. See http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html_single/ and http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/

Give all the rows you want to hide a class name that you can use for hiding. Use javascript to add/remove this class from the different rows.

<table>
<tr><th>Test Table</th><tr>
<tr class="toHide"><td>123456789</td><tr>
<tr class="toHide"><td>123456789</td><tr>
<tr class="toHide"><td>123456789</td><tr>
</table>

CSS:

.toHide
{
 display: none;
}

Have the style for the parent div and the child divs' set as following. It worked for my case, hope it helps you as well..

<div id="parentDiv">
  <div id="backdrop"><img alt="" src='/backdrop.png' /></div>
  <div id="curtain" style="background-image:url(/curtain.png);background-position:100px 200px; height:250px; width:500px;">&nbsp;</div>
</div>

in your JS:

document.getElementById('parentDiv').style.position = 'relative';
document.getElementById('backdrop').style.position = 'absolute';
document.getElementById('curtain').style.position = 'absolute';
document.getElementById('curtain').style.zIndex= '2';//this number has to be greater than the zIndex of 'backdrop' if you are setting any

or in your CSS as in this working example:::

#parentDiv{_x000D_
  background: yellow;_x000D_
  height: 500px;_x000D_
  width: 500px;_x000D_
  position: relative;_x000D_
}_x000D_
#backdrop{_x000D_
  background: red;_x000D_
  height: 300px;_x000D_
  width: 300px;_x000D_
  position: absolute;_x000D_
}_x000D_
#curtain{_x000D_
  background: green;_x000D_
  height: 100px;_x000D_
  width: 100px;_x000D_
  position: absolute;_x000D_
  z-index: 2;_x000D_
  margin: 100px 0px 150px 100px;_x000D_
}

<div id="parentDiv"><h2>_x000D_
  THIS IS PARENT DIV_x000D_
  </h2>_x000D_
  <div id="backdrop"><h4>_x000D_
  THIS IS BACKDROP DIV_x000D_
  </h4></div>_x000D_
  <div id="curtain"><h6>_x000D_
  THIS IS CURTAIN DIV_x000D_
  </h6></div>_x000D_
</div>

Yes right the static array is created at the compile time where as the dynamic array is created on the run time. Where as the difference as far is concerned with their memory locations the static are located on the stack and the dynamic are created on the heap. Everything which gets located on heap needs the memory management until and unless garbage collector as in the case of .net framework is present otherwise there is a risk of memory leak.

You can use validDate.setTime(strDate) Have a look at the javadoc at http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html

In case anyone was curious, I was able to figure this out based on all of your responses combined!

This is in the Facelet:

<h:form id="myform">
  <h:inputSecret value="#{createNewPassword.newPassword1}" id="newPassword1" />
  <h:message class="error" for="newPassword1" id="newPassword1Error" />
  <h:inputSecret value="#{createNewPassword.newPassword2}" id="newPassword2" />
  <h:message class="error" for="newPassword2" id="newPassword2Error" />
  <h:commandButton value="Continue" action="#{createNewPassword.continueButton}" />
</h:form>

This is in the continueButton() method:

FacesContext.getCurrentInstance().addMessage("myForm:newPassword1", new FacesMessage(PASSWORDS_DONT_MATCH, PASSWORDS_DONT_MATCH));

And it works! Thanks for the help!

// Search string exist in employee name finding.
var empName:NSString! = employeeDetails[filterKeyString] as NSString

Case sensitve search.
let rangeOfSearchString:NSRange! = empName.rangeOfString(searchString, options: NSStringCompareOptions.CaseInsensitiveSearch)

// Not found.
if rangeOfSearchString.location != Foundation.NSNotFound
{
    // search string not found in employee name.
}
// Found
else
{
    // search string found in employee name.
}

        //returns System Clipboard
        final Clipboard clipboard = Clipboard.getSystemClipboard();
        // ClipboardContent provides flexibility to store data in different formats
        final ClipboardContent content = new ClipboardContent();
        content.putString("Some text");
        content.putHtml("<b>Some</b> text");
        //this will be replaced by previous putString
        content.putString("Some different text");
        //set the content to clipboard
        clipboard.setContent(content);
       // validate before retrieving it
        if(clipboard.hasContent(DataFormat.HTML)){
            System.out.println(clipboard.getHtml());
        }
        if(clipboard.hasString()){
            System.out.println(clipboard.getString());
        }

ClipboardContent can save multiple data in several data formats like(html,url,plain text,image).

The new(ish) string format method lets you do some fun stuff with nested keyword arguments. The simplest case:

>>> '{message: <16}'.format(message='Hi')
'Hi             '

If you want to pass in 16 as a variable:

>>> '{message: <{width}}'.format(message='Hi', width=16)
'Hi              '

If you want to pass in variables for the whole kit and kaboodle:

'{message:{fill}{align}{width}}'.format(
   message='Hi',
   fill=' ',
   align='<',
   width=16,
)

Which results in (you guessed it):

'Hi              '

And for all these, you can use python 3.6 f-strings:

message = 'Hi'
fill = ' '
align = '<'
width = 16
f'{message:{fill}{align}{width}}'

And of course the result:

'Hi              '

var y = [1,2,3,4,5,6,7,8,9,10];_x000D_
_x000D_
console.log(y.slice((y.length - 5), y.length))

you can do this!

From Python Documentation:

An except clause may name multiple exceptions as a parenthesized tuple, for example

except (IDontLikeYouException, YouAreBeingMeanException) as e:
    pass

Or, for Python 2 only:

except (IDontLikeYouException, YouAreBeingMeanException), e:
    pass

Separating the exception from the variable with a comma will still work in Python 2.6 and 2.7, but is now deprecated and does not work in Python 3; now you should be using as.

Your Maven is reading Java version as 1.6.0_65, Where as the pom.xml says the version is 1.7.

Try installing the required verison.

If already installed check your $JAVA_HOME environment variable, it should contain the path of Java JDK 7. If you dont find it, fix your environment variable.

also remove the lines

 <fork>true</fork>
     <executable>${JAVA_1_7_HOME}/bin/javac</executable>

from the pom.xml

Dump all custom variables:

<h1>Variables passed to the view:</h1>
{% for key, value in _context %}
    {% if key starts with '_' %}
    {% else %}
        <pre style="background: #eee">{{ key }}</pre>
        {{ dump(value) }}
    {% endif %}
{% endfor %}

You can use my plugin which will do that for you (an will nicely format the output):

In Linux, you can issue kill -TSTP <pid> to the background and stop a process. So, it's there, but not consuming CPU time.

Then later, kill -CONT <pid> and it's off and running again.

To get the Color from Hex.

using System.Windows.Media;

Color color = (Color)ColorConverter.ConvertFromString("#FFDFD991");

and then set the foreground

textBlock.Foreground = new System.Windows.Media.SolidColorBrush(color); 

Yes, they can. If you do not have a rooted phone/tablet, then you could download c4droid here to compile your apps. Then, you could download Kevin Boone's KBOX here to run the program.

I was not getting the RSA fingerprint pop up on my phone.

I had to delete the C:\Users\<userName>\.android\adbkey and adbkey.pub files and then do kill and restart of adb server.

adb kill-server
adb start-server

I had to stop and restart the debugger and connecting as USB in PTP mode.

Because the RSA authorisation key was getting stored in this path, killing and restarting the adb server didn't help.
