The following javascript and python scripts give identical outputs. I think it's what you are looking for.

JavaScript

new Date().toISOString()

Python

from datetime import datetime

datetime.utcnow().isoformat()[:-3]+'Z'

The output they give is the utc (zelda) time formatted as an ISO string with a 3 millisecond significant digit and appended with a Z.

The issue arises when the image is not present on the cluster and k8s engine is going to pull the respective registry. k8s Engine enables 3 types of ImagePullPolicy mentioned :

1. Always : It always pull the image in container irrespective of changes in the image
2. Never : It will never pull the new image on the container
3. IfNotPresent : It will pull the new image in cluster if the image is not present.

Best Practices : It is always recommended to tag the new image in both docker file as well as k8s deployment file. So That it can pull the new image in container.

I would like to add a standard library option (i.e. cross-platform) how to generate exception backtraces, which has become available with C++11:

Use std::nested_exception and std::throw_with_nested

This won't give you a stack unwind, but in my opinion the next best thing. It is described on StackOverflow here and here, how you can get a backtrace on your exceptions inside your code without need for a debugger or cumbersome logging, by simply writing a proper exception handler which will rethrow nested exceptions.

Since you can do this with any derived exception class, you can add a lot of information to such a backtrace! You may also take a look at my MWE on GitHub, where a backtrace would look something like this:

Library API: Exception caught in function 'api_function'
Backtrace:
~/Git/mwe-cpp-exception/src/detail/Library.cpp:17 : library_function failed
~/Git/mwe-cpp-exception/src/detail/Library.cpp:13 : could not open file "nonexistent.txt"

I use a slightly more concise version:

expect(() => {
  // Code block that should throw error
}).toThrow(TypeError) // Or .toThrow('expectedErrorMessage')

My way of doing this, based on the log view, only needs to modify the file app/Providers/AppServiceProvider.php:

1. Add this code into app/Providers/AppServiceProvider.php

/**
 * Bootstrap any application services.
 *
 * @return void
 */
public function boot()
{
    //
    DB::listen(function ($query) {
        $querySql = str_replace(['?'], ['\'%s\''], $query->sql);
        $queryRawSql = vsprintf($querySql, $query->bindings);
        Log::debug('[SQL EXEC]', [
                "raw sql"  => $queryRawSql,
                "time" => $query->time,
            ]
        );
    });
}

2. My sql handle code :

$users = DB::table('users')
    ->select(DB::raw('count(*) as user_count, username '))
    ->where('uid', '>=', 10)
    ->limit(100)
    ->groupBy('username')
    ->get()
;
dd($users);

3. See log storage/logs/laravel-2019-10-27.log :

[2019-10-27 17:39:17] local.DEBUG: [SQL EXEC] {"raw sql":"select count(*) as user_count, username  from `users` where `uid` >= '10' group by `username` limit 100","time":304.21} 

For me, other answers didn't work. I had to go to open Files and do Invalidate caches and restart on Intellij. After that, everything worked fine again.

I was able to fix this by: 1) Sign in as the old user. 2) Sign out. 3) Sign in as new user.

In my case, it appears that it wanted to verify my license on the old account first, before it would let me switch to a new one.

Much simpler approach is to use OdeToCode.UseNodeModules Nuget package. I just tested it with .Net Core 3.0. All you need to do is add the package to the solution and reference it in the Configure method of the Startup class:

app.UseNodeModules();

I learned about it from the excellent Building a Web App with ASP.NET Core, MVC, Entity Framework Core, Bootstrap, and Angular Pluralsight course by Shawn Wildermuth.

jdk 6 comes with wsimport that u can use to create Java-classes from a WSDL. It also creates a Service-class.

http://docs.oracle.com/javase/6/docs/technotes/tools/share/wsimport.html

If you are using Underscore.js or Lodash, there is a function 'omit' that will do it.
http://underscorejs.org/#omit

var thisIsObject= {
    'Cow' : 'Moo',
    'Cat' : 'Meow',
    'Dog' : 'Bark'
};
_.omit(thisIsObject,'Cow'); //It will return a new object

=> {'Cat' : 'Meow', 'Dog' : 'Bark'}  //result

If you want to modify the current object, assign the returning object to the current object.

thisIsObject = _.omit(thisIsObject,'Cow');

With pure JavaScript, use:

delete thisIsObject['Cow'];

Another option with pure JavaScript.

thisIsObject.cow = undefined;

thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

The recommended way in Python 3.5 and above is to use subprocess.run():

from subprocess import run
output = run("pwd", capture_output=True).stdout

In my app, user experience is better if more memory is used, so I have to decide if I really should free all the memory I can in didReceiveMemoryWarning. Based on Split's and Jasper Pol's answer, using a maximum of 45% of the total device memory appears to be a safe threshold (thanks guys).

In case someone wants to look at my actual implementation:

#import "mach/mach.h"

- (void)didReceiveMemoryWarning
{
    // Remember to call super
    [super didReceiveMemoryWarning];

    // If we are using more than 45% of the memory, free even important resources,
    // because the app might be killed by the OS if we don't
    if ([self __getMemoryUsedPer1] > 0.45)
    {
        // Free important resources here
    }

    // Free regular unimportant resources always here
}

- (float)__getMemoryUsedPer1
{
    struct mach_task_basic_info info;
    mach_msg_type_number_t size = sizeof(info);
    kern_return_t kerr = task_info(mach_task_self(), MACH_TASK_BASIC_INFO, (task_info_t)&info, &size);
    if (kerr == KERN_SUCCESS)
    {
        float used_bytes = info.resident_size;
        float total_bytes = [NSProcessInfo processInfo].physicalMemory;
        //NSLog(@"Used: %f MB out of %f MB (%f%%)", used_bytes / 1024.0f / 1024.0f, total_bytes / 1024.0f / 1024.0f, used_bytes * 100.0f / total_bytes);
        return used_bytes / total_bytes;
    }
    return 1;
}

Swift (based on this answer):

func __getMemoryUsedPer1() -> Float
{
    let MACH_TASK_BASIC_INFO_COUNT = (sizeof(mach_task_basic_info_data_t) / sizeof(natural_t))
    let name = mach_task_self_
    let flavor = task_flavor_t(MACH_TASK_BASIC_INFO)
    var size = mach_msg_type_number_t(MACH_TASK_BASIC_INFO_COUNT)
    var infoPointer = UnsafeMutablePointer<mach_task_basic_info>.alloc(1)
    let kerr = task_info(name, flavor, UnsafeMutablePointer(infoPointer), &size)
    let info = infoPointer.move()
    infoPointer.dealloc(1)
    if kerr == KERN_SUCCESS
    {
        var used_bytes: Float = Float(info.resident_size)
        var total_bytes: Float = Float(NSProcessInfo.processInfo().physicalMemory)
        println("Used: \(used_bytes / 1024.0 / 1024.0) MB out of \(total_bytes / 1024.0 / 1024.0) MB (\(used_bytes * 100.0 / total_bytes)%%)")
        return used_bytes / total_bytes
    }
    return 1
}

If you want to check if some string is present in another string, use something like String.contains

If you want to check if some pattern is present in a string, append and prepend the pattern with '.*'. The result will accept strings that contain the pattern.

Example: Suppose you have some regex a(b|c) that checks if a string matches ab or ac
.*(a(b|c)).* will check if a string contains a ab or ac.

A disadvantage of this method is that it will not give you the location of the match.

Incase someone is still trying to figure this out. This is how you get the center X and Y of the view.

    int pos[] = new int[2];
    view.getLocationOnScreen(pos);
    int centerX = pos[0] + view.getMeasuredWidth() / 2;
    int centerY = pos[1] + view.getMeasuredHeight() / 2;

You can and should never assume that $_SERVER['HTTP_REFERER'] will be present.

If you control the previous page, you can pass the URL as a parameter "site.com/page2.php?prevUrl=".urlencode("site.com/page1.php").

If you don't control the page, then there is nothing you can do.

I recently came across Python 3 interpreter at CompileOnline.

It depends where exactly you want to get the information from. You have a bunch of options:

• If you have a copy of the .apk, it's just a case of opening it as a zip file and looking at the AndroidManifest.xml file. The top level <manifest> element will have a package attribute.
• If you have the app installed on a device and can connect using adb, you can launch adb shell and execute pm list packages -f, which shows the package name for each installed apk.
• If you just want to manually find a couple of package names, you can search for the app on http://www.cyrket.com/m/android/, and the package name is shown in the URL
• You can also do it progmatically from an Android app using the PackageManager

Once you've got the package name, you simply link to market://search?q=pname:<package_name> or http://market.android.com/search?q=pname:<package_name>. Both will open the market on an Android device; the latter obviously has the potential to work on other hardware as well (it doesn't at the minute).

Does it have to be a string[] ? A List<String> would give you what you need.

List<String> testing = new List<String>();
testing.Add("One");
testing.Add("Two");
testing.Add("Three");
testing.Add("Mouse");
bool inList = testing.Contains("Mouse");

The error message indicates that you have not installed bash, or it is not in your PATH.

The top Google hit is http://win-bash.sourceforge.net/ but you also need to understand that most Bash scripts expect a Unix-like environment; so just installing Bash is probably unlikely to allow you to run a script you found on the net, unless it was specifically designed for this particular usage scenario. The usual solution to that is https://www.cygwin.com/ but there are many possible alternatives, depending on what exactly it is that you want to accomplish.

If Windows is not central to your usage scenario, installing a free OS (perhaps virtualized) might be the simplest way forward.

The second error message is due to the fact that Windows nominally accepts forward slash as a directory separator, but in this context, it is being interpreted as a switch separator. In other words, Windows parses your command line as app /build /build.sh (or, to paraphrase with Unix option conventions, app --build --build.sh). You could try app\build\build.sh but it is unlikely to work, because of the circumstances outlined above.

You need to remove the /var/lib/mysql folder. Also, purge when you remove the packages (I'm told this helps).

sudo apt-get remove --purge mysql-server mysql-client mysql-common

sudo rm -rf /var/lib/mysql

I was encountering similar issues. The second line got rid of my issues and allowed me to set up MySql from scratch. Hopefully it helps you too!

For cross origin sharing, set header: 'Access-Control-Allow-Origin':'*';

Php: header('Access-Control-Allow-Origin':'*');

Node: app.use('Access-Control-Allow-Origin':'*');

This will allow to share content for different domain.

Python >= 3.5 alternative: unpack into a list literal [*newdict]

New unpacking generalizations (PEP 448) were introduced with Python 3.5 allowing you to now easily do:

>>> newdict = {1:0, 2:0, 3:0}
>>> [*newdict]
[1, 2, 3]

Unpacking with * works with any object that is iterable and, since dictionaries return their keys when iterated through, you can easily create a list by using it within a list literal.

Adding .keys() i.e [*newdict.keys()] might help in making your intent a bit more explicit though it will cost you a function look-up and invocation. (which, in all honesty, isn't something you should really be worried about).

_{The *iterable syntax is similar to doing list(iterable) and its behaviour was initially documented in the Calls section of the Python Reference manual. With PEP 448 the restriction on where *iterable could appear was loosened allowing it to also be placed in list, set and tuple literals, the reference manual on Expression lists was also updated to state this.}

Though equivalent to list(newdict) with the difference that it's faster (at least for small dictionaries) because no function call is actually performed:

%timeit [*newdict]
1000000 loops, best of 3: 249 ns per loop

%timeit list(newdict)
1000000 loops, best of 3: 508 ns per loop

%timeit [k for k in newdict]
1000000 loops, best of 3: 574 ns per loop

with larger dictionaries the speed is pretty much the same (the overhead of iterating through a large collection trumps the small cost of a function call).

In a similar fashion, you can create tuples and sets of dictionary keys:

>>> *newdict,
(1, 2, 3)
>>> {*newdict}
{1, 2, 3}

beware of the trailing comma in the tuple case!

Alternatively, you can add it to the URL and let the scripting language (PHP, Perl, ASP, Python, Ruby, whatever) handle it on the other side. Something like:

var x = 10;
window.open('mypage.php?x='+x);

Simply put list(yourQuerySet).

To answer the question of going from an existing python datetime to a pandas Timestamp do the following:

    import time, calendar, pandas as pd
    from datetime import datetime
    
    def to_posix_ts(d: datetime, utc:bool=True) -> float:
        tt=d.timetuple()
        return (calendar.timegm(tt) if utc else time.mktime(tt)) + round(d.microsecond/1000000, 0)
    
    def pd_timestamp_from_datetime(d: datetime) -> pd.Timestamp:
        return pd.to_datetime(to_posix_ts(d), unit='s')
    
    dt = pd_timestamp_from_datetime(datetime.now())
    print('({}) {}'.format(type(dt), dt))

Output:

(<class 'pandas._libs.tslibs.timestamps.Timestamp'>) 2020-09-05 23:38:55

I was hoping for a more elegant way to do this but the to_posix_ts is already in my standard tool chain so I'm moving on.

from openpyxl import load_workbook

sheets = load_workbook(excel_file, read_only=True).sheetnames

For a 5MB Excel file I'm working with, load_workbook without the read_only flag took 8.24s. With the read_only flag it only took 39.6 ms. If you still want to use an Excel library and not drop to an xml solution, that's much faster than the methods that parse the whole file.

You can stub a static void method like this:

PowerMockito.doNothing().when(StaticResource.class, "getResource", anyString());

Although I'm not sure why you would bother, because when you call mockStatic(StaticResource.class) all static methods in StaticResource are by default stubbed

More useful, you can capture the value passed to StaticResource.getResource() like this:

ArgumentCaptor<String> captor = ArgumentCaptor.forClass(String.class);
PowerMockito.doNothing().when(
               StaticResource.class, "getResource", captor.capture());

Then you can evaluate the String that was passed to StaticResource.getResource like this:

String resourceName = captor.getValue();

To initialize 2d array with zero use the below method: int arr[n][m] = {};

NOTE : The above method will only work to initialize with 0;

Just use the plain ol' class selector.

$('#my_id .my_class')

It doesn't matter if the element also has other classes. It has the .my_class class, and it's somewhere inside #my_id, so it will match that selector.

Regarding performance

According to the jQuery selector performance documentation, it's faster to use the two selectors separately, like this:

$('#my_id').find('.my_class')

Here's the relevant part of the documentation:

ID-Based Selectors

// Fast:
$( "#container div.robotarm" );

// Super-fast:
$( "#container" ).find( "div.robotarm" );

The .find() approach is faster because the first selection is handled without going through the Sizzle selector engine – ID-only selections are handled using document.getElementById(), which is extremely fast because it is native to the browser.

Selecting by ID or by class alone (among other things) invokes browser-supplied functions like document.getElementById() which are quite rapid, whereas using a descendent selector invokes the Sizzle engine as mentioned which, although fast, is slower than the suggested alternative.

The keyword you need is flatten an array. Modern javascript array comes with a flat method. You can use third party libraries like underscorejs in case you need to support older browsers.

Native Ex:

var response=[1,2,3,4[12,15],[20,21]];
var data=response.flat(); //data=[1,2,3,4,12,15,20,21]

Underscore Ex:

var response=[1,2,3,4[12,15],[20,21]];
var data=_.flatten(response);

i used following instructions, its so easy to increase virtual box disk size

http://blog.bhupen.me/1/post/2011/09/increase-virtualbox-disk-size.html

I know that this is an old question but I am just going to place this here:

To prevent skype from using port 80 and port 443, open the Skype window, then click on the Tools menu and select Options.
Click on the Advanced tab, and go to the Connection sub-tab.
Uncheck the checkbox for Use port 80 and 443 as an alternative for additional incoming connections option.
Click on the Save button and then restart Skype.
After you restart skype, skype wont use port 88 or 443 anymore.

Hope this might help someone.

If you want to declare the dictionary once and never change it then declare it as readonly:

private static readonly Dictionary<string, string> ErrorCodes
    = new Dictionary<string, string>
{
    { "1", "Error One" },
    { "2", "Error Two" }
};

If you want to dictionary items to be readonly (not just the reference but also the items in the collection) then you will have to create a readonly dictionary class that implements IDictionary.

Check out ReadOnlyCollection for reference.

BTW const can only be used when declaring scalar values inline.

There are three formats with a reasonable level of support: H.264 (MPEG-4 AVC), OGG Theora (VP3) and WebM (VP8). See the wiki linked by Sam for which browsers support which; you will typically need at least one of those plus Flash fallback.

Whilst most browsers won't touch AVI, there are some browser builds that expose all the multimedia capabilities of the underlying OS to <video>. These browser will indeed be able to play AVI, as long as they have matching codecs installed (AVI can contain about a million different video and audio formats). In particular Safari on OS X with QuickTime, or Konqi with GStreamer.

Personally I think this is an absolutely disastrous idea, as it exposes a very large codec codebase to the net, a codebase that was mostly not written to be resistant to network attacks. One of the worst drawbacks of media player plugins was the huge number of security holes they made available to every web page exploit. Let's not make this mistake again.

You say your website is in http://localhost/mywebsite, and let's say that your image is inside a subfolder named pictures/:

Absolute path

If you use an absolute path, / would point to the root of the site, not the root of the document: localhost in your case. That's why you need to specify your document's folder in order to access the pictures folder:

"/mywebsite/pictures/picture.png"

And it would be the same as:

"http://localhost/mywebsite/pictures/picture.png"

Relative path

A relative path is always relative to the root of the document, so if your html is at the same level of the directory, you'd need to start the path directly with your picture's directory name:

"pictures/picture.png"

But there are other perks with relative paths:

dot-slash (./)

Dot (.) points to the same directory and the slash (/) gives access to it:

So this:

"pictures/picture.png"

Would be the same as this:

"./pictures/picture.png"

Double-dot-slash (../)

In this case, a double dot (..) points to the upper directory and likewise, the slash (/) gives you access to it. So if you wanted to access a picture that is on a directory one level above of the current directory your document is, your URL would look like this:

"../picture.png"

You can play around with them as much as you want, a little example would be this:

Let's say you're on directory A, and you want to access directory X.

- root
   |- a
      |- A
   |- b
   |- x
      |- X

Your URL would look either:

Absolute path

"/x/X/picture.png"

Or:

Relative path

"./../x/X/picture.png"

One of the simplest way is to use flatten(), like this example :

 import numpy as np

 batch_y =train_output.iloc[sample, :]
 batch_y = np.array(batch_y).flatten()

My array it was like this :

    0
0   6
1   6
2   5
3   4
4   3
.
.
.

After using flatten():

array([6, 6, 5, ..., 5, 3, 6])

It's also the solution of errors of this type :

Cannot feed value of shape (100, 1) for Tensor 'input/Y:0', which has shape '(?,)' 

if is there only one Top-Level Container then last lines in GUI constructor would be for example

.
.
.
myFrame.setVisible(true);
EventQueue.invokeLater(new Runnable() {

   @Override
     public void run() {
         myComponent.grabFocus();
         myComponent.requestFocus();//or inWindow
     }
});

But still, the memory address for each letter in this address is different.

Memory address is different but as its array of characters they are sequential. When you pass address of first element and use %s, printf will print all characters starting from given address until it finds '\0'.

You have to pass a function to expect. Like this:

expect(model.get.bind(model, 'z')).to.throw('Property does not exist in model schema.');
expect(model.get.bind(model, 'z')).to.throw(new Error('Property does not exist in model schema.'));

The way you are doing it, you are passing to expect the result of calling model.get('z'). But to test whether something is thrown, you have to pass a function to expect, which expect will call itself. The bind method used above creates a new function which when called will call model.get with this set to the value of model and the first argument set to 'z'.

A good explanation of bind can be found here.

?? should be preferred to || because it checks only for nulls and undefined.

All The expressions below are true:

(null || 'x') === 'x' ;
(undefined || 'x') === 'x' ;
//Most of the times you don't want the result below
('' || 'x') === 'x'  ;
(0 || 'x') === 'x' ;
(false || 'x') === 'x' ;
//-----

//Using ?? is preferred
(null ?? 'x') === 'x' ;
(undefined ?? 'x') === 'x' ;
//?? works only for null and undefined, which is in general safer
('' ?? 'x') === '' ;
(0 ?? 'x') === 0 ;
(false ?? 'x') === false ;

Bottom line:

int j=i ?? 10; is perfectly fine to use in javascript also. Just replace int with let.

Asterisk: Check browser compatibility and if you really need to support these other browsers use babel.

Within Spring Boot 2.4 it is

Mikepenz's Alternative Answer needed some changes in my case. https://stackoverflow.com/a/22345538/12021422 Major Credits to Mikepenz's Answer which I could modify.

Here is the Plug and Play static function that worked for me.

Just pass the Context of Application and this function will handle the restart.

    public static void doRestart(Context c) {
        try {
            // check if the context is given
            if (c != null) {
                // fetch the package manager so we can get the default launch activity
                // (you can replace this intent with any other activity if you want
                PackageManager pm = c.getPackageManager();
                // check if we got the PackageManager
                if (pm != null) {
                    // create the intent with the default start activity for your application

            e.printStackTrace();
            Log.e("restart", "Could not Restart");

There is better solution for Oracle instead of using dbms_random.value, while it requires full scan to order rows by dbms_random.value and it is quite slow for large tables.

Use this instead:

SELECT *
FROM employee sample(1)
WHERE rownum=1

It may appear to be overly awkward, but you're probably better off unsetting one element at a time rather than the entire $_POST array. Here's why: If you're using object-oriented programming, you may have one class use $_POST['alpha'] and another class use $_POST['beta'], and if you unset the array after first use, it will void its use in other classes. To be safe and not shoot yourself in the foot, just drop in a little method that will unset the elements that you've just used: For example:

private function doUnset()
{
    unset($_POST['alpha']);
    unset($_POST['gamma']);
    unset($_POST['delta']);
    unset($_GET['eta']);
    unset($_GET['zeta']);
}

Just call the method and unset just those superglobal elements that have been passed to a variable or argument. Then, the other classes that may need a superglobal element can still use them.

However, you are wise to unset the superglobals as soon as they have been passed to an encapsulated object.

var wrapper = $(document.body);

    ], function(key, value) {
        $("<span>" + value + "</span>").appendTo(wrapper);
    }); 
});

myList[1] is an element of myList and it's type is string.

myList[1] is str, you can not append to it. myList is a list, you should have been appending to it.

>>> myList[2]
[1, 2]

Migration files must match the pattern *_*.php, or else they won't be found. Since users.php does not match this pattern (it has no underscore), this file will not be found by the migrator.

Ideally, you should be creating your migration files using artisan:

php artisan make:migration create_users_table

This will create the file with the appropriate name, which you can then edit to flesh out your migration. The name will also include the timestamp, to help the migrator determine the order of migrations.

You can also use the --create or --table switches to add a little bit more boilerplate to help get you started:

php artisan make:migration create_users_table --create=users

The documentation on migrations can be found here.

Here's a macro that allows you to shuffle selected cells in a column:

Option Explicit

Sub ShuffleSelectedCells()
  'Do nothing if selecting only one cell
  If Selection.Cells.Count = 1 Then Exit Sub
  'Save selected cells to array
  Dim CellData() As Variant
  CellData = Selection.Value
  'Shuffle the array
  ShuffleArrayInPlace CellData
  'Output array to spreadsheet
  Selection.Value = CellData
End Sub

Sub ShuffleArrayInPlace(InArray() As Variant)
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' ShuffleArrayInPlace
' This shuffles InArray to random order, randomized in place.
' Source: http://www.cpearson.com/excel/ShuffleArray.aspx
' Modified by Tom Doan to work with Selection.Value two-dimensional arrays.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
  Dim J As Long, _
    N As Long, _
    Temp As Variant
  'Randomize
  For N = LBound(InArray) To UBound(InArray)
    J = CLng(((UBound(InArray) - N) * Rnd) + N)
    If J <> N Then
      Temp = InArray(N, 1)
      InArray(N, 1) = InArray(J, 1)
      InArray(J, 1) = Temp
    End If
  Next N
End Sub

You can read the comments to see what the macro is doing. Here's how to install the macro:

1. Open the VBA editor (Alt + F11).
2. Right-click on "ThisWorkbook" under your currently open spreadsheet (listed in parentheses after "VBAProject") and select Insert / Module.
3. Paste the code above and save the spreadsheet.

Now you can assign the "ShuffleSelectedCells" macro to an icon or hotkey to quickly randomize your selected rows (keep in mind that you can only select one column of rows).

I faced multiple time the same issue that I add device info to portal so I can publish build to fabric testing but device is still missing due to how Xcode is not updating team provisioning profile.

So based on other answers and my own experience, the best and quickest way is to remove all Provisioning profiles manually by command line while automatic signing will download them again with updated devices.

If this can lead to some unknown issues I don't know and highly doubt, but it works for me just fine.

So just:

cd ~/Library/MobileDevice/Provisioning\ Profiles/
rm *

And try again...

<table style="width: auto;" ... works fine. Tested in Chrome 38 , IE 11 and Firefox 34.

jsfiddle : http://jsfiddle.net/rpaul/taqodr8o/

What worked for me was

git reset HEAD app/views/data/landingpage.js.erb
git restore app/views/data/landingpage.js.erb

where the file I wanted to restore was app/views/data/landingpage.js.erb

I really like stackPusher's ConvertToLetter function as a solution. However, in working with it I noticed several errors occurring at very specific inputs due to some flaws in the math. For example, inputting 392 returns 'N\', 418 returns 'O\', 444 returns 'P\', etc.

I reworked the function and the result produces the correct output for all input up to 703 (which is the first triple-letter column index, AAA).

Function ConvertToLetter2(iCol As Integer) As String
    Dim First As Integer
    Dim Second As Integer
    Dim FirstChar As String
    Dim SecondChar As String

    First = Int(iCol / 26)
    If First = iCol / 26 Then
        First = First - 1
    End If
    If First = 0 Then
        FirstChar = ""
    Else
        FirstChar = Chr(First + 64)
    End If

    Second = iCol Mod 26
    If Second = 0 Then
        SecondChar = Chr(26 + 64)
    Else
        SecondChar = Chr(Second + 64)
    End If

    ConvertToLetter2 = FirstChar & SecondChar

End Function

With Bootstrap 4.1 I found a width solution by percentage:

This is because the shell script is formatted in windows we need to change to unix format. You can run the dos2unix command on any Linux system.

dos2unix your-file.sh

If you don’t have access to a Linux system, you may use the Git Bash for Windows which comes with a dos2unix.exe

dos2unix.exe your-file.sh 

You are looking for a simple code, like this:

    List<string> tagList = new List<string>(new[]
    {
         "A"
        ,"B"
        ,"C"
        ,"D"
        ,"E"
    });

I installed Visual Studio 2012 and installed Visual Studio 2010 service package 1 and tried installing the SDK again, and it worked. I don't know which of them solved the problem.

I had the same issue, although the module that it was downloading was different. The only resolution to the problem is run the below command again:

npm install

import datetime
def today_date():
    '''
    utils:
    get the datetime of today
    '''
    date=datetime.datetime.now().date()
    date=pd.to_datetime(date)
    return date
Df['Date'] = today_date()

this could be safely used in pandas dataframes.

There are many options how to write a regex pattern for that

• ^(?:(?!0)\d{1,2}|100)$
• ^(?:[1-9]\d?|100)$
• ^(?!0)(?=100$|..$|.$)\d+$

If you have already created a localhost connection and its still showing can not connect then goto taskbar and find the MySQL notifier icon. Click on that and check whether your connection name is running or stopped. If its stopped then start or restart. I was facing the same issue but it fixed my problem.

use android:layout_gravity instead of android:gravity

android:gravity sets the gravity of the content of the View its used on. android:layout_gravity sets the gravity of the View or Layout in its parent.

I've been integrating a lot of stuff into Python lately, including Java. The most robust method I've found is to use IKVM and a C# wrapper.

IKVM has a neat little application that allows you to take any Java JAR, and convert it directly to .Net DLL. It simply translates the JVM bytecode to CLR bytecode. See http://sourceforge.net/p/ikvm/wiki/Ikvmc/ for details.

The converted library behaves just like a native C# library, and you can use it without needing the JVM. You can then create a C# DLL wrapper project, and add a reference to the converted DLL.

You can now create some wrapper stubs that call the methods that you want to expose, and mark those methods as DllEport. See https://stackoverflow.com/a/29854281/1977538 for details.

The wrapper DLL acts just like a native C library, with the exported methods looking just like exported C methods. You can connect to them using ctype as usual.

I've tried it with Python 2.7, but it should work with 3.0 as well. Works on Windows and the Linuxes

If you happen to use C#, then this is probably the best approach to try when integrating almost anything into python.

FYI, when you define a rule like you did above, with two selectors chained together:

.area1.item
{
    color:red;
}

It means:

Apply this style to any element that has both the class "area1" and "item".

Such as:

<div class="area1 item">

Sadly it doesn't work in IE6, but that's what it means.

Faster way of doing this:

WHERE interests LIKE '%sports%' OR interests LIKE '%pub%'

is this:

WHERE interests REGEXP 'sports|pub'

Found this solution here: http://forums.mysql.com/read.php?10,392332,392950#msg-392950

Looks like some changes to SASS have made possible what you've initially tried doing:

@import "../subdir/common";

We even got this to work for some totally unrelated folder located in c:\projects\sass:

@import "../../../../../../../../../../projects/sass/common";

Just add enough ../ to be sure you'll end up at the drive root and you're good to go.

Of course, this solution is far from pretty, but I couldn't get an import from a totally different folder to work, neither using I c:\projects\sass nor setting the environment variable SASS_PATH (from: :load_paths reference) to that same value.

In playSound(), instead of

for i in range(myList):

try

for i in myList:

This will iterate over the contents of myList, which I believe is what you want. range(myList) doesn't make any sense.

VBA is not VB/VB.NET

The correct reference to use is Do..Loop Statement (VBA). Also see the article Excel VBA For, Do While, and Do Until. One way to write this is:

Do While counter < 20
    counter = counter + 1
Loop

(But a For..Next might be more appropriate here.)

Happy coding.

Even better then @Tanjim Rahman answer you can using Spring Data JPA use the method T getOne(ID id)

Customer customerToUpdate = customerRepository.getOne(id);
customerToUpdate.setName(customerDto.getName);
customerRepository.save(customerToUpdate);

Is's better because getOne(ID id) gets you only a reference (proxy) object and does not fetch it from the DB. On this reference you can set what you want and on save() it will do just an SQL UPDATE statement like you expect it. In comparsion when you call find() like in @Tanjim Rahmans answer spring data JPA will do an SQL SELECT to physically fetch the entity from the DB, which you dont need, when you are just updating.

#define GENERAL__GET_BITS_FROM_U8(source,lsb,msb) \
    ((uint8_t)((source) & \
        ((uint8_t)(((uint8_t)(0xFF >> ((uint8_t)(7-((uint8_t)(msb) & 7))))) & \
             ((uint8_t)(0xFF << ((uint8_t)(lsb) & 7)))))))

#define GENERAL__GET_BITS_FROM_U16(source,lsb,msb) \
    ((uint16_t)((source) & \
        ((uint16_t)(((uint16_t)(0xFFFF >> ((uint8_t)(15-((uint8_t)(msb) & 15))))) & \
            ((uint16_t)(0xFFFF << ((uint8_t)(lsb) & 15)))))))

#define GENERAL__GET_BITS_FROM_U32(source,lsb,msb) \
    ((uint32_t)((source) & \
        ((uint32_t)(((uint32_t)(0xFFFFFFFF >> ((uint8_t)(31-((uint8_t)(msb) & 31))))) & \
            ((uint32_t)(0xFFFFFFFF << ((uint8_t)(lsb) & 31)))))))

There are two ways for this:

If you are using ui-router or $stateProvider, do it as:

$state.go('stateName'); //remember to add $state service in the controller

if you are using angular-router or $routeProvider, do it as:

$location.path('routeName'); //similarily include $location service in your controller

Java:

int offset = TimeZone.getDefault().getRawOffset() + TimeZone.getDefault().getDSTSavings();
long now = System.currentTimeMillis() - offset;

Kotlin:

Int offset = TimeZone.getDefault()rawOffset + TimeZone.getDefault().dstSavings
Long now = System.currentTimeMillis() - offset

sqlite>  insert into t2 select * from t;

CREATE TABLE t(id integer, col2 varchar(32), col3 varchar(8));
CREATE TABLE t2(id integer primary key, col2 varchar(32), col3 varchar(8));
sqlite> drop table t;
sqlite> alter table t2 rename to t;
sqlite> .schema
CREATE TABLE IF NOT EXISTS "t"(id integer primary key, col2 varchar(32), col3 varchar(8));

A VirtualHost would also work for this and may work better for you as you can host several projects without the need for subdirectories. Here's how you do it:

httpd.conf (or extra\httpd-vhosts.conf relative to httpd.conf. Trailing slashes "\" might cause it not to work):

NameVirtualHost *:80
# ...
<VirtualHost *:80>  
    DocumentRoot C:\projects\transitCalculator\trunk\
    ServerName transitcalculator.localhost
    <Directory C:\projects\transitCalculator\trunk\>  
        Order allow,deny  
        Allow from all  
    </Directory>
</VirtualHost> 

HOSTS file (c:\windows\system32\drivers\etc\hosts usually):

# localhost entries
127.0.0.1 localhost transitcalculator.localhost

Now restart XAMPP and you should be able to access http://transitcalculator.localhost/ and it will map straight to that directory.

This can be helpful if you're trying to replicate a production environment where you're developing a site that will sit on the root of a domain name. You can, for example, point to files with absolute paths that will carry over to the server:

<img src="/images/logo.png" alt="My Logo" />

whereas in an environment using aliases or subdirectories, you'd need keep track of exactly where the "images" directory was relative to the current file.

Could you not have simply added:

align-items:center;

to a new class in your row div. Essentially:

<div class="row align_center">

.align_center { align-items:center; }

 select  CONCAT(UCASE(LEFT('CHRIS', 1)),SUBSTRING(lower('CHRIS'),2));

Above statement can be used for first letter CAPS and rest as lower case.

The right place to download the JDK for Java 7 is Java SE Downloads.

All the other links provided above, as far as I can tell, either provide the JRE or Java 6 downloads (incidentally, if you want to run Eclipse or other IDEs, like IntelliJ IDEA, you will need the JDK, not the JRE).

Regarding IntelliJ IDEA - that will still ask you to install Java 6 as it apparently needs an older class loader or something: just follow the instructions when the dialog pop-up appears and it will install the JDK 6 in the right place.

Afterwards, you will need to do the sudo ln -snf mentioned in the answer above:

sudo ln -nsf /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents \
    /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

(copied here as it was mentioned that "above" may eventually not make sense as answers are re-sorted).

I also set my JAVA_HOME to point to where jdk_1.7.0_xx.jdk was installed:

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home"

Then add that to your PATH:

export PATH=$JAVA_HOME/bin:$PATH

The alternative is to fuzz around with Apple's insane maze of hyperlinks, but honestly life is too short to bother.

Django database objects use the same save() method for creating and changing objects.

obj = Product.objects.get(pk=pk)
obj.name = "some_new_value"
obj.save()

How Django knows to UPDATE vs. INSERT
If the object’s primary key attribute is set to a value that evaluates to True (i.e., a value other than None or the empty string), Django executes an UPDATE. If the object’s primary key attribute is not set or if the UPDATE didn’t update anything, Django executes an INSERT.

You have to add repositories to your build file. For maven repositories you have to prefix repository name with maven{}

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "http://maven.restlet.org" }
  mavenCentral()
}

There are 3 different ways you may wish to set this up:

1. Thrower inside of Catcher
2. Catcher inside of Thrower
3. Thrower and Catcher inside of another class in this example Test

THE WORKING GITHUB EXAMPLE I AM CITING Defaults to Option 3, to try the others simply uncomment the "Optional" code block of the class you want to be main, and set that class as the ${Main-Class} variable in the build.xml file:

4 Things needed on throwing side code:

import java.util.*;//import of java.util.event

//Declaration of the event's interface type, OR import of the interface,
//OR declared somewhere else in the package
interface ThrowListener {
    public void Catch();
}
/*_____________________________________________________________*/class Thrower {
//list of catchers & corresponding function to add/remove them in the list
    List<ThrowListener> listeners = new ArrayList<ThrowListener>();
    public void addThrowListener(ThrowListener toAdd){ listeners.add(toAdd); }
    //Set of functions that Throw Events.
        public void Throw(){ for (ThrowListener hl : listeners) hl.Catch();
            System.out.println("Something thrown");
        }
////Optional: 2 things to send events to a class that is a member of the current class
. . . go to github link to see this code . . .
}

2 Things needed in a class file to receive events from a class

/*_______________________________________________________________*/class Catcher
implements ThrowListener {//implement added to class
//Set of @Override functions that Catch Events
    @Override public void Catch() {
        System.out.println("I caught something!!");
    }
////Optional: 2 things to receive events from a class that is a member of the current class
. . . go to github link to see this code . . .
}

We can write directly too...

DECLARE @SearchLetter CHAR(1) 

SET @SearchLetter = 'A' 

SELECT * 
FROM   CUSTOMERS 
WHERE  CONTACTNAME LIKE @SearchLetter + '%' 
       AND REGION = 'WY' 

or the following way as well if we have to append all the search characters then,

DECLARE @SearchLetter CHAR(1) 

SET @SearchLetter = 'A' + '%' 

SELECT * 
FROM   CUSTOMERS 
WHERE  CONTACTNAME LIKE @SearchLetter 
       AND REGION = 'WY' 

Both these will work

AndroidStudio is alpha version for now. So you have to edit gradle build script files by yourself. Add next lines to your build.gradle

android {

    signingConfigs {

        release {

            storeFile file('android.keystore')
            storePassword "pwd"
            keyAlias "alias"
            keyPassword "pwd"
        }
    }

    buildTypes {

       release {

           signingConfig signingConfigs.release
       }
    }
}

To actually run your application at emulator or device run gradle installDebug or gradle installRelease.

You can create helloworld project from AndroidStudio wizard to see what structure of gradle files is needed. Or export gradle files from working eclipse project. Also this series of articles are helpfull http://blog.stylingandroid.com/archives/1872#more-1872

There are two common "security" implications to using GET. Since data appears in the URL string its possible someone looking over your shoulder at Address Bar/URL may be able to view something they should not be privy to such as a session cookie that could potentially be used to hijack your session. Keep in mind everyone has camera phones.

The other security implication of GET has to do with GET variables being logged to most web servers access log as part of the requesting URL. Depending on the situation, regulatory climate and general sensitivity of the data this can potentially raise concerns.

Some clients/firewalls/IDS systems may frown upon GET requests containing an excessive amount of data and may therefore provide unreliable results.

POST supports advanced functionality such as support for multi-part binary input used for file uploads to web servers.

POST requires a content-length header which may increase the complexity of an application specific client implementation as the size of data submitted must be known in advance preventing a client request from being formed in an exclusively single-pass incremental mode. Perhaps a minor issue for those choosing to abuse HTTP by using it as an RPC (Remote Procedure Call) transport.

Others have already done a good job in covering the semantic differences and the "when" part of this question.

As far as I can tell there is no upper limit in 2008.

In SQL Server 2005 the code in your question fails on the assignment to the @GGMMsg variable with

Attempting to grow LOB beyond maximum allowed size of 2,147,483,647 bytes.

the code below fails with

REPLICATE: The length of the result exceeds the length limit (2GB) of the target large type.

However it appears these limitations have quietly been lifted. On 2008

DECLARE @y VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),92681); 

SET @y = REPLICATE(@y,92681);

SELECT LEN(@y) 

Returns

8589767761

I ran this on my 32 bit desktop machine so this 8GB string is way in excess of addressable memory

Running

select internal_objects_alloc_page_count
from sys.dm_db_task_space_usage
WHERE session_id = @@spid

Returned

internal_objects_alloc_page_co 
------------------------------ 
2144456    

so I presume this all just gets stored in LOB pages in tempdb with no validation on length. The page count growth was all associated with the SET @y = REPLICATE(@y,92681); statement. The initial variable assignment to @y and the LEN calculation did not increase this.

The reason for mentioning this is because the page count is hugely more than I was expecting. Assuming an 8KB page then this works out at 16.36 GB which is obviously more or less double what would seem to be necessary. I speculate that this is likely due to the inefficiency of the string concatenation operation needing to copy the entire huge string and append a chunk on to the end rather than being able to add to the end of the existing string. Unfortunately at the moment the .WRITE method isn't supported for varchar(max) variables.

Addition

I've also tested the behaviour with concatenating nvarchar(max) + nvarchar(max) and nvarchar(max) + varchar(max). Both of these allow the 2GB limit to be exceeded. Trying to then store the results of this in a table then fails however with the error message Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. again. The script for that is below (may take a long time to run).

DECLARE @y1 VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),2147483647); 
SET @y1 = @y1 + @y1;
SELECT LEN(@y1), DATALENGTH(@y1)  /*4294967294, 4294967292*/


DECLARE @y2 NVARCHAR(MAX) = REPLICATE(CAST('X' AS NVARCHAR(MAX)),1073741823); 
SET @y2 = @y2 + @y2;

The "SNAPSHOT" term means that the build is a snapshot of your code at a given time.

It usually means that this version is still under heavy development.

When the code is ready and it is time to release it, you will want to change the version listed in the POM. Then instead of having a "SNAPSHOT" you would use a label like "1.0".

For some help with versioning, check out the Semantic Versioning specification.

It'll reset the CSS effectively, getting rid of the padding and margins.

$(".testClick").click(function () {
         var value = $(this).attr("href");
         alert(value );     
}); 

When you use $(".className") you are getting the set of all elements that have that class. Then when you call attr it simply returns the value of the first item in the collection.

If you have GNU parallel you could convert all .avi files below vid_dir to mp4 in parallel, using all except one of your CPU cores with

find vid_dir -type f -name '*.avi' -not -empty -print0 |
    parallel -0 -j -1 ffmpeg -loglevel fatal -i {} {.}.mp4

To convert from/to different formats, change '*.avi' or .mp4 as needed. GNU parallel is listed in most Linux distributions' repositories in a package which is usually called parallel.

I simply hadn't referenced my class library that contained the EDMX file.

But an error occurred which says java.lang.NullPointerException.

Thats because, you never initialized your MainActivity. you should initialize your object before you call its methods.

MainActivity mActivity = new MainActivity();//make sure that you pass the appropriate arguments if you have an args constructor
mActivity.startChronometer();

This particular commands worked for me. sudo apt-get remove --purge nginx nginx-full nginx-common

and sudo apt-get install nginx

Instead of [(ngModel)] you can use:

// view
<input type="date" #myDate [value]="demoUser.date | date:'yyyy-MM-dd'" (input)="demoUser.date=parseDate($event.target.value)" />

// controller
parseDate(dateString: string): Date {
    if (dateString) {
        return new Date(dateString);
    }
    return null;
}

You can also choose not to use parseDate function. In this case the date will be saved as string format like "2016-10-06" instead of Date type (I haven't tried whether this has negative consequences when manipulating the data or saving to database for example).

As cartman pointed out, you can use any kind of hash value for finding exact duplicates.

One starting point for finding close images could be here. This is a tool used by CG companies to check if revamped images are still showing essentially the same scene.

INSTALL_FAILED_NO_MATCHING_ABIS is when you are trying to install an app that has native libraries and it doesn't have a native library for your cpu architecture. For example if you compiled an app for armv7 and are trying to install it on an emulator that uses the Intel architecture instead it will not work.

Using Xamarin on Visual Studio 2015. Fix this issue by:

1. Open your xamarin .sln
2. Right click your android project
3. Click properties
4. Click Android Options
5. Click the 'Advanced' tab

6. Under "Supported architectures" make the following checked:

   1. armeabi-v7a
   2. x86

7. save

8. F5 (build)

Edit: This solution has been reported as working on Visual Studio 2017 as well.

Edit 2: This solution has been reported as working on Visual Studio 2017 for Mac as well.

Try this:

USE master;

GO;
 
GRANT ADMINISTER BULK OPERATIONS TO shira;

Rounding a decimal to the nearest integer

decimal a ;
int b = (int)(a + 0.5m);

when a = 49.9, then b = 50

when a = 49.5, then b = 50

when a = 49.4, then b = 49 etc.

You could add the following mapping to your .vimrc

vnoremap <silent> # :s/^/#/<cr>:noh<cr>
vnoremap <silent> -# :s/^#//<cr>:noh<cr>

Highlight your block with:

Shift+v

# to comment your lines from the first column.

-# to uncomment the same way.

you can achieve this by using flutter_launcher_icons in pubspec.yaml

another way is to use one for android and another one for iOS

According to this SO thread, the solution is to use the non-primitive wrapper types; e.g., Integer instead of int.

This doesn't seem to be relevant in this case, but in case others face this problem --- make sure that if you installed 32 bit version of Eclipse, you also installed 32 bit version of JRE. Similarly, if you installed 64 bit version of Eclipse, you need 64 bit version of JRE in your Windows. Otherwise you will see the above error message as well.

Just use ansible_ssh_host variable

playbook_example.yml

- hosts: host1
  tasks:
  - name: Show host's ip
    debug:
      msg: "{{ ansible_ssh_host }}"

hosts.yml

[hosts]
host1   ansible_host=1.2.3.4

Result

TASK [Show host's ip] *********************************************************************************************************************************************************************************************
ok: [host1] => {
     "msg": "1.2.3.4"
}

When this happened to me (out of nowhere) I was about to dive into the top answer above, and then I figured I'd close the project, close Visual Studio, and then re-open everything. Problem solved. VS bug?

Just to note that nginx has now support for Websockets on the release 1.3.13. Example of use:

location /websocket/ {

    proxy_pass ?http://backend_host;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_read_timeout 86400;

}

You can also check the nginx changelog and the WebSocket proxying documentation.

I found that after much struggle, trial and error, the best solution for me on jsfiddle. Link to inspiration on jsfiddle.net. I am using bootstrap's navbar navbar-fixed-top with collapse and hamburger toggle. Here is my version on jsfiddle: jsfiddle Scrollspy navbar. I was only getting basic functionality using the instructions on getbootsrap.com. For me, the problem was mostly in the vague directions and js recommended by the getbootstrap site. The best part was that adding this extra bit of js (which does include some of what is mentioned in the above threads) solved several Scrollspy issues for me including:

1. Collapsed/toggled nav menu hides when nav "section" (e.g. href="#foobar") is clicked (issue addressing this thread).
2. Active "section" was successfully highlighted (ie. js successfully created class="active")
3. Annoying vertical scroll bar found on collapsed nav (only on small screens) was eliminated.

NOTE: In the js code shown below (from the second jsfiddle link in my post):

topMenu = $("#myScrollspy"),

...the value "myScrollspy" must match it the id="" in your HTML like so...

<nav id="myScrollspy" class="navbar navbar-default navbar-fixed-top">

Of course you can change that value to whatever value you like.

I'm not sure I understand the problem.

I you want to change the status bar color programmatically (and provided the device has Android 5.0) then you can use Window.setStatusBarColor(). It shouldn't make a difference whether the activity is derived from Activity or ActionBarActivity.

Just try doing:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    Window window = getWindow();
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    window.setStatusBarColor(Color.BLUE);
}

Just tested this with ActionBarActivity and it works alright.

Note: Setting the FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag programmatically is not necessary if your values-v21 styles file has it set already, via:

    <item name="android:windowDrawsSystemBarBackgrounds">true</item>

I had to start Workbench as Administrator. Apparently it didn't have the required permissions to connect to my localhost database server process.

Right-click the Workbench shortcut and select Run as Administrator. In the shortcut's Properties window, you can click on "Advanced" and tick the box next to "Run as Administrator" to always run the Workbench with Admin privileges.

We don't need a LabelEncoder.

You can convert the columns to categoricals and then get their codes. I used a dictionary comprehension below to apply this process to every column and wrap the result back into a dataframe of the same shape with identical indices and column names.

>>> pd.DataFrame({col: df[col].astype('category').cat.codes for col in df}, index=df.index)
   location  owner  pets
0         1      1     0
1         0      2     1
2         0      0     0
3         1      1     2
4         1      3     1
5         0      2     1

To create a mapping dictionary, you can just enumerate the categories using a dictionary comprehension:

>>> {col: {n: cat for n, cat in enumerate(df[col].astype('category').cat.categories)} 
     for col in df}

{'location': {0: 'New_York', 1: 'San_Diego'},
 'owner': {0: 'Brick', 1: 'Champ', 2: 'Ron', 3: 'Veronica'},
 'pets': {0: 'cat', 1: 'dog', 2: 'monkey'}}

On MacOS you may also just stop Dropbox, make your changes and then relaunch Dropbox. I am using the following combination and am quite happy with it:

In both (your local git managed project directory and your remote git repository located on Dropbox) run the following command to disable auto-packing (which is the main problem with dropbox syncing)

git config --global gc.auto 0

Then from time to time, compress the repositories with dropbox disabled. For example I do the following in my bash-build-script whenever I make new releases of my apps.

osascript -e "tell application \"Dropbox\" to quit"

# Compress local
git gc --prune=now; git repack -a -d

# Compress remote
REPOS_DIR_REMOTE=`git remote get-url --push origin`
cd "${REPOS_DIR_REMOTE}"
git gc --prune=now; git repack -a -d

osascript -e "tell application \"Dropbox\" to launch"
osascript -e "display notification with title \"Compress Done\""

add some css:

td, th {
   border:none;
}

Yes - just do it this way:

WITH DependencedIncidents AS
(
  ....
),  
lalala AS
(
  ....
)

You don't need to repeat the WITH keyword

i used this script to add alternative image

function imgError()
{
alert('The image could not be loaded.');
}

HTML:

<img src="image.gif" onerror="imgError()" />

http://wap.w3schools.com/jsref/event_onerror.asp

this is to disable dropdown2 , dropdown 3 if you select the option from dropdown1 that has the value 15

$("#dropdown1").change(function(){
            if ( $(this).val()!= "15" ) {
                $("#dropdown2").attr("disabled",true);
                $("#dropdown13").attr("disabled",true);

            }

Use SHOW OPEN TABLES: http://dev.mysql.com/doc/refman/5.1/en/show-open-tables.html

You can do something like this

SHOW OPEN TABLES WHERE `Table` LIKE '%[TABLE_NAME]%' AND `Database` LIKE '[DBNAME]' AND In_use > 0;

to check any locked tables in a database.

I also had problem understanding next() , but this helped

var app = require("express")();

app.get("/", function(httpRequest, httpResponse, next){
    httpResponse.write("Hello");
    next(); //remove this and see what happens 
});

app.get("/", function(httpRequest, httpResponse, next){
    httpResponse.write(" World !!!");
    httpResponse.end();
});

app.listen(8080);

TempData is also a dictionary object that stays for the time of an HTTP Request. So, TempData can be used to maintain data between one controller action to the other controller action.

TempData is used to check the null values each time. TempData contain two method keep() and peek() for maintain data state from one controller action to others.

When TempDataDictionary object is read, At the end of request marks as deletion to current read object.

The keep() and peek() method is used to read the data without deletion the current read object.

You can use Peek() when you always want to hold/prevent the value for another request. You can use Keep() when prevent/hold the value depends on additional logic.

Overloading in TempData.Peek() & TempData.Keep() as given below.

TempData.Keep() have 2 overloaded methods.

1. void keep() : That menace all the data not deleted on current request completion.

2. void keep(string key) : persist the specific item in TempData with help of name.

TempData.Peek() no overloaded methods.

1. object peek(string key) : return an object that contain items with specific key without making key for deletion.

Example for return type of TempData.Keep() & TempData.Peek() methods as given below.

public void Keep(string key) { _retainedKeys.Add(key); }

public object Peek(string key) { object value = values; return value; }

I often use the following:

c := b
if a > b {
    c = a
}

basically the same as @Not_a_Golfer's but using type inference.

In PHP 7 you can write it even shorter:

$age = $_GET['age'] ?? 27;

This means that the $age variable will be set to the age parameter if it is provided in the URL, or it will default to 27.

See all new features of PHP 7.

import random
result=[]
for i in range(1,50):
    rng=random.randint(1,20)
    result.append(rng)

The problem with merge sort is the merge, if you don't actually need to implement the merge, then it is pretty simple (for a vector of ints):

#include <algorithm>
#include <vector>
using namespace std;

typedef vector<int>::iterator iter;

void mergesort(iter b, iter e) {
    if (e -b > 1) {
        iter m = b + (e -b) / 2;
        mergesort(b, m);
        mergesort(m, e);
        inplace_merge(b, m, e);
    }
}

I had a similar situation. On top of what you did, I wanted to center my columns in the container while not allowing empty columns to for them left or right:

.grid { 
    display: grid;
    grid-gap: 10px;
    justify-content: center;
    grid-template-columns: repeat(auto-fit, minmax(200px, auto));
}

List<T>.ForEach doesn't play particularly well with async (neither does LINQ-to-objects, for the same reasons).

In this case, I recommend projecting each element into an asynchronous operation, and you can then (asynchronously) wait for them all to complete.

using (DataContext db = new DataLayer.DataContext())
{
    var tasks = db.Groups.ToList().Select(i => GetAdminsFromGroupAsync(i.Gid));
    var results = await Task.WhenAll(tasks);
}

The benefits of this approach over giving an async delegate to ForEach are:

1. Error handling is more proper. Exceptions from async void cannot be caught with catch; this approach will propagate exceptions at the await Task.WhenAll line, allowing natural exception handling.
2. You know that the tasks are complete at the end of this method, since it does an await Task.WhenAll. If you use async void, you cannot easily tell when the operations have completed.
3. This approach has a natural syntax for retrieving the results. GetAdminsFromGroupAsync sounds like it's an operation that produces a result (the admins), and such code is more natural if such operations can return their results rather than setting a value as a side effect.

Simple plot,

you can use:

df.plot(x='Date',y='adj_close')

Or you can set the index to be Date beforehand, then it's easy to plot the column you want:

df.set_index('Date', inplace=True)
df['adj_close'].plot()

If you want a chart with one series by ticker on it

You need to groupby before:

df.set_index('Date', inplace=True)
df.groupby('ticker')['adj_close'].plot(legend=True)

If you want a chart with individual subplots:

grouped = df.groupby('ticker')

ncols=2
nrows = int(np.ceil(grouped.ngroups/ncols))

fig, axes = plt.subplots(nrows=nrows, ncols=ncols, figsize=(12,4), sharey=True)

for (key, ax) in zip(grouped.groups.keys(), axes.flatten()):
    grouped.get_group(key).plot(ax=ax)

ax.legend()
plt.show()

Since you imported the project as a General Project, it does not have the java nature and that is the problem.

Add the below lines in the .project file of your workspace and refresh.

<natures>
      <nature>org.eclipse.jdt.core.javanature</nature>
</natures>

UPDATE: The Android Studio with NDK support is out now: http://tools.android.com/tech-docs/android-ndk-preview

For building with a script the gradle solution below should work:

I am using my build script and added to my file (Seems to work for 0.8+): This seems to be equivalent to the solution below (but looks nicer in the gradle file):

 android {
    sourceSets {
        main {
            jniLibs.srcDirs = ['native-libs']
            jni.srcDirs = [] //disable automatic ndk-build
        }
    }
 }

The build unfortunately does not fail if the directory is not present or contains no .so files.

You can use the infoDictionary which gets the version details from info.plist of you app. This code works for swift 3. Just call this method and display the version in any preferred UI element.

Swift-3  

func getVersion() -> String {
    let dictionary = Bundle.main.infoDictionary!
    let version = dictionary["CFBundleShortVersionString"] as! String
    let build = dictionary["CFBundleVersion"] as! String
    return "v\(version).\(build)"
}

I use this code String result = args[0].replace("\\n", "\n");

public class HelloWorld {

    public static void main(String[] args) {
        String result = args[0].replace("\\n", "\n");
        System.out.println(result);
    }
}

with terminal I can use arg I\\nam\\na\\boy to make System.out.println print out

I
am
a
boy

I'm not sure this is a right way but I solved it by adding display: inline-block; to the wrapper div.

#wrapper{
    display: inline-block;
    /*border: 1px black solid;*/
    width: 75%;
    min-width: 800px;
}

.content{
    text-align: justify; 
    float: right; 
    width: 90%;
}

.lbar{
    text-align: justify; 
    float: left; 
    width: 10%;
}

This is how I do it.

import numpy as np

def dt2cal(dt):
    """

        numpy.ndarray of datetimes of arbitrary shape

    # allocate output 
    out = np.empty(dt.shape + (7,), dtype="u4")
    # decompose calendar floors
    Y, M, D, h, m, s = [dt.astype(f"M8[{x}]") for x in "YMDhms"]
    out[..., 0] = Y + 1970 # Gregorian Year
    out[..., 1] = (M - Y) + 1 # month
    out[..., 2] = (D - M) + 1 # dat
    out[..., 3] = (dt - D).astype("m8[h]") # hour

    return out

It's vectorized across arbitrary input dimensions, it's fast, its intuitive, it works on numpy v1.15.4, it doesn't use pandas.

I really wish numpy supported this functionality, it's required all the time in application development. I always get super nervous when I have to roll my own stuff like this, I always feel like I'm missing an edge case.

Your question title mentions Blocking Queues. However, ConcurrentLinkedQueue is not a blocking queue.

The BlockingQueues are ArrayBlockingQueue, DelayQueue, LinkedBlockingDeque, LinkedBlockingQueue, PriorityBlockingQueue, and SynchronousQueue.

Some of these are clearly not fit for your purpose (DelayQueue, PriorityBlockingQueue, and SynchronousQueue). LinkedBlockingQueue and LinkedBlockingDeque are identical, except that the latter is a double-ended Queue (it implements the Deque interface).

Since ArrayBlockingQueue is only useful if you want to limit the number of elements, I'd stick to LinkedBlockingQueue.

Here's a hack I discovered that might work for you, although its not pretty and I'd personally be embarrassed to use such a line of code:

ng-click="profileForm.$valid ? updateMyProfile() : alert('failed')"

Now, you must be thinking 'but I don't want it to alert("failed") if my profileForm isn't valid. Well that's the ugly part. For me, no matter what I put in the else clause of this ternary statement doesn't get executed ever.

Yet if its removed an error is thrown. So you can just stuff it with a pointless alert.
I told you it was ugly... but I don't even get any errors when I do something like this.
The proper way to do this is as Chen-Tsu mentioned, but to each their own.

I accidentally encoded a file in UTF-7 and had a similar issue. When I typed file -i name.file I would get charset=us-ascii.

iconv -f us-ascii -t utf-9//translit name.file would not work since I've gathered UTF-7 is a subset of US ASCII, as is UTF-8.

To solve this, I entered

iconv -f UTF-7 -t UTF-8//TRANSLIT name.file -o output.file

I'm not sure how to determine the encoding other than what others have suggested here.

seeing it in digital circuit domain

1. A Wire will create a wire output which can only be assigned any input by using assign statement as assign statement creates a port/pin connection and wire can be joined to the port/pin
2. A reg will create a register(D FLIP FLOP ) which gets or recieve inputs on basis of sensitivity list either it can be clock (rising or falling ) or combinational edge .

so it completely depends on your use whether you need to create a register and tick it according to sensitivity list or you want to create a port/pin assignment

For setting Top Border and Bottom Border for a UIView in Swift.

let topBorder = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 1))
topBorder.backgroundColor = UIColor.black
myView.addSubview(topBorder)

let bottomBorder = UIView(frame: CGRect(x: 0, y: myView.frame.size.height - 1, width: 10, height: 1))
bottomBorder.backgroundColor = UIColor.black
myView.addSubview(bottomBorder)

From cppreference, one of the std::unique_ptr constructors is

explicit unique_ptr( pointer p ) noexcept;

So to create a new std::unique_ptr is to pass a pointer to its constructor.

unique_ptr<int> uptr (new int(3));

Or it is the same as

int *int_ptr = new int(3);
std::unique_ptr<int> uptr (int_ptr);

The different is you don't have to clean up after using it. If you don't use std::unique_ptr (smart pointer), you will have to delete it like this

delete int_ptr;

when you no longer need it or it will cause a memory leak.

>>> item = set([0,1,2,3,4,5,6,7,8,9])
>>> z = set([2,3,4])
>>> print item - z
set([0, 1, 5, 6, 7, 8, 9])

In short, place black behind the image, and lower the opactiy. You can do this by wrapping the image within a div, and then lowering the opacity of the image.

For example:

<!DOCTYPE html>

<style>
    .img-wrap {
        background: black;
        display: inline-block;
        line-height: 0;
    }
        .img-wrap > img {
            opacity: 0.8;
        }
</style>

<div class="img-wrap">
    <img src="http://mikecane.files.wordpress.com/2007/03/kitten.jpg" />
</div>

Here is a JSFiddle.

Seems like you forgot the ["value"] or ->value:

echo $data[0]->weather->weatherIconUrl[0]->value;

Once I ran into a similar error. Let me describe it.

Edit.js

   // components returns edit form 
   
   function EditVideo({id}) {
   .....
   
   // onChange event listener 
    const handleChange = (e) => {
       setTextData({
           ...textData,
           [e.target.name]: e.target.value.trim()
        });
     }
  
   ....
   ...
   }
)

ImportEdit.js

   import Edit from './Edit';
   
    function ImportEdit() {
    ......
     ...
    return (
        <div>
            <EditVideo id={id}/>
        </div>
       )
    }

    export default ImportEdit

The Problem was: I was unable to use spacebar (i.e. if i press spacekey, i didn't see space input)

The Bug: .trim()

.trim() method was trimming all the white space i typed

Note: Edit.js worked fine when used sepeartely without import

Try this CSS:

h1 {

Open a terminal and run the keytool utility provided with Java to get the SHA-1 fingerprint of the certificate. You should get both the release and debug certificate fingerprints.

To get the release certificate fingerprint: keytool -exportcert -list -v \ -alias -keystore

This might be what you are after, although depending on how many style_id's there are, it would be tricky to implement (not sure if those style_id's are static or not). If this is the case, then it is not really possible what you are wanting as the WHERE clause works on a row to row basis.

WITH cte as (
  SELECT
    image_id,
    max(decode(style_id,24,style_value)) AS style_colour,
    max(decode(style_id,25,style_value)) AS style_size,
    max(decode(style_id,27,style_value)) AS style_shape
  FROM
    list
  GROUP BY
    image_id
)
SELECT
  image_id
FROM
  cte
WHERE
  style_colour = 'red'
  and style_size = 'big'
  and style_shape = 'round'

Your target domain might refuse to send you information. This can work as a filter based on browser agent or any other header information. This is a defense against bots, crawlers or any unwanted applications.

The ASIDE has since been modified to include secondary content as well.

HTML5 Doctor has a great writeup on it here: http://html5doctor.com/aside-revisited/

Excerpt:

With the new definition of aside, it’s crucial to remain aware of its context. >When used within an article element, the contents should be specifically related >to that article (e.g., a glossary). When used outside of an article element, the >contents should be related to the site (e.g., a blogroll, groups of additional >navigation, and even advertising if that content is related to the page).

When you call another .bat file, I think you need "call" in front of the call:

The // operator returns the floor of the division. Since dividing by 1 doesn't change your number, this is equivalent to floor but no import is needed. Notes:

1. This returns a float
2. This rounds towards -8

Just call getArguments() in your Frag2's onCreateView() method:

public class Frag2 extends Fragment {

     public View onCreateView(LayoutInflater inflater,
         ViewGroup containerObject,
         Bundle savedInstanceState){
         //here is your arguments
         Bundle bundle=getArguments(); 

        //here is your list array 
        String[] myStrings=bundle.getStringArray("elist");   
     }
}

The easiest is:

Use table style Border-collapse at the table level

you can use the following to check your free (swap) memory

free -m

total used free shared buffers cached

To enable the swap you can use for example:

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1

I would query the information_schema - this has views that are much more readable than the underlying tables.

This is what i have been facing for long time.

This happened last time and figured out that one case could be a bad war deployment, which came after i update library/maven dependencies on pom and re installed it.

SOLUTION:

right click on the server >  remove the war and 
right click on the server again > clean
make sure the maven dependencies are added to deployment assembly
right click on the project > Run As > maven clean
right click on the project again > Run As > maven install 
and finally deploy the project on to the server. This helped me to solve the issue  

I think I read the entire internet to figure out how to get sitemesh to handle my html paths without extension + API paths without extension. I was wrapped up in a straight jacket figuring this out, every turn seemed to break something else. Then I finally came upon this post.

In C# 3, you can do:

IList<string> l = new List<string> { "test1", "test2", "test3" };

This uses the new collection initializer syntax in C# 3.

In C# 2, I would just use your second option.

Files related for deployment (and others temporary items) are created in standalone/tmp/vfs (Virtual File System). You may add a policy at startup for evicting temporary files :

-Djboss.vfs.cache=org.jboss.virtual.plugins.cache.IterableTimedVFSCache 
-Djboss.vfs.cache.TimedPolicyCaching.lifetime=1440

On my machine:

C:\Program Files (x86)\OpenERP 6.1-20121026-233219\PostgreSQL\data

Try this

sudo -u hdfs hdfs dfsadmin -safemode leave

check status of safemode

sudo -u hdfs hdfs dfsadmin -safemode get

If it is still in safemode ,then one of the reason would be not enough space in your node, you can check your node disk usage using :

df -h

if root partition is full, delete files or add space in your root partition and retry first step.

With using guard our intension is clear. we do not want to execute rest of the code if that particular condition is not satisfied. here we are able to extending chain too, please have a look at below code:

 // do stuff here

Check out also the --sig-proxy option:

docker attach --sig-proxy=false 304f5db405ec

Then use CTRL+c to detach

The proper way to do this is to use multiple tables and JOIN them in your queries.

For example:

CREATE TABLE person (
`id` INT NOT NULL PRIMARY KEY,
`name` VARCHAR(50)
);

CREATE TABLE fruits (
`fruit_name` VARCHAR(20) NOT NULL PRIMARY KEY,
`color` VARCHAR(20),
`price` INT
);

CREATE TABLE person_fruit (
`person_id` INT NOT NULL,
`fruit_name` VARCHAR(20) NOT NULL,
PRIMARY KEY(`person_id`, `fruit_name`)
);

The person_fruit table contains one row for each fruit a person is associated with and effectively links the person and fruits tables together, I.E.

1 | "banana"
1 | "apple"
1 | "orange"
2 | "straberry"
2 | "banana"
2 | "apple"

When you want to retrieve a person and all of their fruit you can do something like this:

SELECT p.*, f.*
FROM person p
INNER JOIN person_fruit pf
ON pf.person_id = p.id
INNER JOIN fruits f
ON f.fruit_name = pf.fruit_name

As all of these comments are true, you should note that as far as ICANN approved Arabic (Persian) and Chinese characters to be registered as Domain Name, all of the browser-making companies (Microsoft, Mozilla, Apple, etc.) have to support Unicode in URLs without any encoding, and those should be searchable by Google, etc.

So this issue will resolve ASAP.

Look at how Runtime.getRuntime().exec() passes the String command to the ProcessBuilder. It uses a tokenizer and explodes the command into individual tokens, then invokes exec(String[] cmdarray, ......) which constructs a ProcessBuilder.

If you construct the ProcessBuilder with an array of strings instead of a single one, you'll get to the same result.

The ProcessBuilder constructor takes a String... vararg, so passing the whole command as a single String has the same effect as invoking that command in quotes in a terminal:

shell$ "command with args"

To align one flex child to the right set it withmargin-left: auto;

From the flex spec:

One use of auto margins in the main axis is to separate flex items into distinct "groups". The following example shows how to use this to reproduce a common UI pattern - a single bar of actions with some aligned on the left and others aligned on the right.

.wrap div:last-child {
  margin-left: auto;
}

Note:

You could achieve a similar effect by setting flex-grow:1 on the middle flex item (or shorthand flex:1) which would push the last item all the way to the right. (Demo)

The obvious difference however is that the middle item becomes bigger than it may need to be. Add a border to the flex items to see the difference.

C99 quotes

This answer aims to quote and explain the relevant parts of the C99 N1256 standard draft.

Definition of declarator

The term declarator will come up a lot, so let's understand it.

From the language grammar, we find that the following underline characters are declarators:

int f(int x, int y);
    ^^^^^^^^^^^^^^^

int f(int x, int y) { return x + y; }
    ^^^^^^^^^^^^^^^

int f();
    ^^^

int f(x, y) int x; int y; { return x + y; }
    ^^^^^^^

Declarators are part of both function declarations and definitions.

There are 2 types of declarators:

• parameter type list
• identifier list

Parameter type list

Declarations look like:

int f(int x, int y);

Definitions look like:

int f(int x, int y) { return x + y; }

It is called parameter type list because we must give the type of each parameter.

Identifier list

Definitions look like:

int f(x, y)
    int x;
    int y;
{ return x + y; }

Declarations look like:

int g();

We cannot declare a function with a non-empty identifier list:

int g(x, y);

because 6.7.5.3 "Function declarators (including prototypes)" says:

3 An identifier list in a function declarator that is not part of a definition of that function shall be empty.

It is called identifier list because we only give the identifiers x and y on f(x, y), types come after.

This is an older method, and shouldn't be used anymore. 6.11.6 Function declarators says:

1 The use of function declarators with empty parentheses (not prototype-format parameter type declarators) is an obsolescent feature.

and the Introduction explains what is an obsolescent feature:

Certain features are obsolescent, which means that they may be considered for withdrawal in future revisions of this International Standard. They are retained because of their widespread use, but their use in new implementations (for implementation features) or new programs (for language [6.11] or library features [7.26]) is discouraged

f() vs f(void) for declarations

When you write just:

void f();

it is necessarily an identifier list declaration, because 6.7.5 "Declarators" says defines the grammar as:

direct-declarator:
    [...]
    direct-declarator ( parameter-type-list )
    direct-declarator ( identifier-list_opt )

so only the identifier-list version can be empty because it is optional (_opt).

direct-declarator is the only grammar node that defines the parenthesis (...) part of the declarator.

So how do we disambiguate and use the better parameter type list without parameters? 6.7.5.3 Function declarators (including prototypes) says:

10 The special case of an unnamed parameter of type void as the only item in the list specifies that the function has no parameters.

So:

void f(void);

is the way.

This is a magic syntax explicitly allowed, since we cannot use a void type argument in any other way:

void f(void v);
void f(int i, void);
void f(void, int);

What can happen if I use an f() declaration?

Maybe the code will compile just fine: 6.7.5.3 Function declarators (including prototypes):

14 The empty list in a function declarator that is not part of a definition of that function specifies that no information about the number or types of the parameters is supplied.

So you can get away with:

void f();
void f(int x) {}

Other times, UB can creep up (and if you are lucky the compiler will tell you), and you will have a hard time figuring out why:

void f();
void f(float x) {}

See: Why does an empty declaration work for definitions with int arguments but not for float arguments?

f() and f(void) for definitions

f() {}

vs

f(void) {}

are similar, but not identical.

6.7.5.3 Function declarators (including prototypes) says:

14 An empty list in a function declarator that is part of a definition of that function specifies that the function has no parameters.

which looks similar to the description of f(void).

But still... it seems that:

int f() { return 0; }
int main(void) { f(1); }

is conforming undefined behavior, while:

int f(void) { return 0; }
int main(void) { f(1); }

is non conforming as discussed at: Why does gcc allow arguments to be passed to a function defined to be with no arguments?

TODO understand exactly why. Has to do with being a prototype or not. Define prototype.

This works for me on OSX:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n'

It returns the list one per line:

1.1.0rc1
1.1.0rc2
1.1.0
1.2.0rc1
1.2.0rc2
1.2.0rc3
1.2.0rc4
1.2.0
1.3.0rc1

1.10.0rc1
1.10.0rc2

Or to get the latest version available:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n' \
| gsort -r -V \
| head -1

1.10.0rc2

Keep in mind gsort has to be installed (on OSX) to parse the versions. You can install it with brew install coreutils

$update = \DB::table('student') ->where('id', $data['id']) ->limit(1) ->update( [ 'name' => $data['name'], 'address' => $data['address'], 'email' => $data['email'], 'contactno' => $data['contactno'] ]); 

Or:

SELECT SUM(foo), DATE(mydate) mydate FROM a_table GROUP BY mydate;

More efficient (I think.) Because you don't have to cast mydate twice per row.

It's the part of the .NET Framework that isn't contained within the Client Profile. See MSDN for more info; specifically:

The .NET Framework is made up of the .NET Framework 4 Client Profile and .NET Framework 4 Extended components that exist separately in Programs and Features.

Assuming the first answer is referring to the C-like syntax (char *)(0x135700 +0xec1a04f) then the answer to do rwatch *0x135700+0xec1a04f is incorrect. The correct syntax is rwatch *(0x135700+0xec1a04f).

The lack of ()s there caused me a great deal of pain trying to use watchpoints myself.

Only Visual Studio 2015 Enterprise has code coverage built-in. See the feature matrix for details.

You can use the OpenCover.UI extension for code coverage check inside Visual Studio. It supports MSTest, nUnit, and xUnit.

The new version can be downloaded from here (release notes).

Other answers posted here for this question did not work for me using the latest Visual Studio 2017 Enterprise edition (as of 2018-09-18).

Instead, I used this method:

1. Close all but one instance of Visual Studio.
2. In the running instance, access the menu Tools->Extensions and Updates.
3. In that dialog, choose Online->Visual Studio Marketplace->Tools->Setup & Deployment.
4. From the list that appears, select Microsoft Visual Studio 2017 Installer Projects.

Once installed, close and restart Visual Studio. Go to File->New Project and search for the word Installer. You'll know you have the correct templates installed if you see a list that looks something like this:

select unique is not valid syntax for what you are trying to do

you want to use either select distinct or select distinctrow

And actually, you don't even need distinct/distinctrow in what you are trying to do. You can eliminate duplicates by choosing the appropriate union statement parameters.

the below query by itself will only provide distinct values

select col from table1 
union 
select col from table2

if you did want duplicates you would have to do

select col from table1 
union all
select col from table2

As far as I can see, you just added heredoc by mistake
No need to use ugly heredoc syntax here.
Just remove it and everything will work:

<p>Hello</p>
<p><?= _("World"); ?></p>

It operates on the whole IIS process tree, as opposed to just your application pools.

C:\>iisreset /?

                        on the local system.

A shell convention is that a successful executable should exit with the value 0. Anything else can be interpreted as a failure of some sort, on part of bash or the executable you that just ran. See also $PIPESTATUS and the EXIT STATUS section of the bash man page:

   For  the shell’s purposes, a command which exits with a zero exit status has succeeded.  An exit status
   of zero indicates success.  A non-zero exit status indicates failure.  When a command terminates  on  a
   fatal signal N, bash uses the value of 128+N as the exit status.

   If  a command is not found, the child process created to execute it returns a status of 127.  If a com-
   mand is found but is not executable, the return status is 126.

   If a command fails because of an error during expansion or redirection, the exit status is greater than
   zero.

   Shell  builtin  commands  return  a  status of 0 (true) if successful, and non-zero (false) if an error
   occurs while they execute.  All builtins return an exit status of 2 to indicate incorrect usage.

   Bash itself returns the exit status of the last command executed, unless  a  syntax  error  occurs,  in
   which case it exits with a non-zero value.  See also the exit builtin command below.

Some platforms may support width and precision specification between % and the letter (such as 'd' for day of month), according to http://docs.python.org/library/time.html -- but it's definitely a non-portable solution (e.g. doesn't work on my Mac;-). Maybe you can use a string replace (or RE, for really nasty format) after the strftime to remedy that? e.g.:

>>> y
(2009, 5, 7, 17, 17, 17, 3, 127, 1)
>>> time.strftime('%Y %m %d', y)
'2009 05 07'
>>> time.strftime('%Y %m %d', y).replace(' 0', ' ')
'2009 5 7'

$this->where('email', $email)->where('password', $password) 

is returning a Builder object which you could use to append more where filters etc.

To get the result you need:

$userRecord = $this->where('email', $email)->where('password', $password)->first();

Whoa. You're really over-complicating it by a very long distance. Try:

>>> print hex(0x12ef ^ 0xabcd)
0xb922

You seem to be ignoring these handy facts, at least:

• Python has native support for hexadecimal integer literals, with the 0x prefix.
• "Hexadecimal" is just a presentation detail; the arithmetic is done in binary, and then the result is printed as hex.
• There is no connection between the format of the inputs (the hexadecimal literals) and the output, there is no such thing as a "hexadecimal number" in a Python variable.
• The hex() function can be used to convert any number into a hexadecimal string for display.

If you already have the numbers as strings, you can use the int() function to convert to numbers, by providing the expected base (16 for hexadecimal numbers):

>>> print int("12ef", 16)
4874

So you can do two conversions, perform the XOR, and then convert back to hex:

>>> print hex(int("12ef", 16) ^ int("abcd", 16))
0xb922

when you create an object using predefine class, at first you want to create a variable for storing that object. Then you can create object and store variable that you created.

class Student:
     def __init__(self):

# creating an object....

   student1=Student()

Actually this init method is the constructor of class.you can initialize that method using some attributes.. In that point , when you creating an object , you will have to pass some values for particular attributes..

class Student:
      def __init__(self,name,age):
            self.name=value
            self.age=value

 # creating an object.......

     student2=Student("smith",25)

Let's assume this is your class:

class Test
{
    private $baz = 1;

    public function foo() { ... }

    public function bar() 
    {
        printf("baz = %d\n", $this->baz);
    }

    public static function staticMethod() { echo "static method\n"; }
}

From within the foo() method, let's look at the different options:

$this->staticMethod();

So that calls staticMethod() as an instance method, right? It does not. This is because the method is declared as public static the interpreter will call it as a static method, so it will work as expected. It could be argued that doing so makes it less obvious from the code that a static method call is taking place.

$this::staticMethod();

Since PHP 5.3 you can use $var::method() to mean <class-of-$var>::; this is quite convenient, though the above use-case is still quite unconventional. So that brings us to the most common way of calling a static method:

self::staticMethod();

Now, before you start thinking that the :: is the static call operator, let me give you another example:

self::bar();

This will print baz = 1, which means that $this->bar() and self::bar() do exactly the same thing; that's because :: is just a scope resolution operator. It's there to make parent::, self:: and static:: work and give you access to static variables; how a method is called depends on its signature and how the caller was called.

To see all of this in action, see this 3v4l.org output.

Have you tried adding a configsection handler to your app.config? e.g.

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>

If you need a PEM file without any password you can use this solution.

Just copy and paste the private key and the certificate to the same file and save as .pem.

The file will look like:

-----BEGIN PRIVATE KEY-----
............................
............................
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...........................
...........................
-----END CERTIFICATE-----

That's the only way I found to upload certificates to Cisco devices for HTTPS.

The individual alphabets or symbols residing in a single cell can be inserted into different cells in different columns by the following code:

For i = 1 To Len(Cells(1, 1))
Cells(2, i) = Mid(Cells(1, 1), i, 1)
Next

If you do not want the symbols like colon to be inserted put an if condition in the loop.

I installed Astro file manager and searched for a previous version of the apk-file, found one on the sdcard and deleted the apk-file using Astro file manager.

Use onchage function

<input type="radio" name="bedStatus" id="allot" checked="checked" value="allot" onchange="my_function('allot')">Allot
<input type="radio" name="bedStatus" id="transfer" value="transfer" onchange="my_function('transfer')">Transfer

<script>
 function my_function(val){
    alert(val);
 }
</script>

The same can be achieved from ssms client itself. Just open the ssms, insert the server name and then from options under heading connection properties make sure Trust server certificate is checked.

You can use =A4, in case A4 is having long formula

Taken from the Multimarkdown Users Guide (thanks to @MultiMarkdown on Twitter for pointing it out)

[Some Text][]will link to a header named “Some Text”
e.g.

### Some Text ###

An optional label of your choosing to help disambiguate cases where multiple headers have the same title:

### Overview [MultiMarkdownOverview] ##

This allows you to use [MultiMarkdownOverview] to refer to this section specifically, and not another section named Overview. This works with atx- or settext-style headers.

If you have already defined an anchor using the same id that is used by a header, then the defined anchor takes precedence.

In addition to headers within the document, you can provide labels for images and tables which can then be used for cross-references as well.

If your problem is retaining the Console Window within Visual Studio without modifying your application (c-code) and are running it with Ctrl+F5 (when running Ctrl+F5) but the window is still closing the principal hint is to set the /SUBSYSTEM:CONSOLE linker option in your Visual Studio project.

as explained by DJMooreTX in http://social.msdn.microsoft.com/Forums/en-US/vcprerelease/thread/21073093-516c-49d2-81c7-d960f6dc2ac6

1) Open up your project, and go to the Solution Explorer. If you're following along with me in K&R, your "Solution" will be 'hello' with 1 project under it, also 'hello' in bold.

2. Right click on the 'hello" (or whatever your project name is.)

3. Choose "Properties" from the context menu.

4. Choose Configuration Properties>Linker>System.

5. For the "Subsystem" property in the right-hand pane, click the drop-down box in the right hand column.

6. Choose "Console (/SUBSYSTEM:CONSOLE)"

7. Click Apply, wait for it to finish doing whatever it does, then click OK. (If "Apply" is grayed out, choose some other subsystem option, click Apply, then go back and apply the console option. My experience is that OK by itself won't work.)

Now do Boris' CTRL-F5, wait for your program to compile and link, find the console window under all the other junk on your desktop, and read your program's output, followed by the beloved "Press any key to continue...." prompt.

Again, CTRL-F5 and the subsystem hints work together; they are not separate options.

This is not directly related to the initial issue, but probably will help somebody.

I faced same issue when was trying to send similar request using domain account. So mine issue was in not escaped character in login name.

Bad example:

'ABC\username'

Good example:

'ABC\\username'

writing data in tables declared declare @tb and after joining with other tables, I realized that the response time compared to temporary tables tempdb .. # tb is much higher.

When I join them with @tb the time is much longer to return the result, unlike #tm, the return is almost instantaneous.

I did tests with a 10,000 rows join and join with 5 other tables

All of the other answers are basically right but I don't think anyone's directly answered your original question.

Assuming that "date_and_time" in your example is a column with type DATE or TIMESTAMP, I think you just need to change this:

to_char(date_and_time + (.000694 * 31))

to this:

to_char(date_and_time + (.000694 * 31), 'DD-MON-YYYY HH24:MI')

It sounds like your default date format uses the "HH" code for the hour, not "HH24".

Also, I think your constant term is both confusing and imprecise. I guess what you did is calculate that (.000694) is about the value of a minute, and you are multiplying it by the number of minutes you want to add (31 in the example, although you said 30 in the text).

I would also start with a day and divide it into the units you want within your code. In this case, (1/48) would be 30 minutes; or if you wanted to break it up for clarity, you could write ( (1/24) * (1/2) ).

This would avoid rounding errors (except for those inherent in floating point which should be meaningless here) and is clearer, at least to me.

set /a countfiles-=%countfiles%

This will set countfiles to 0. I think you want to decrease it by 1, so use this instead:

set /a countfiles-=1

I'm not sure if the for loop will work, better try something like this:

:loop
cscript /nologo c:\deletefile.vbs %BACKUPDIR%
set /a countfiles-=1
if %countfiles% GTR 21 goto loop

import requests
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
data = requests.get(url).json

maybe?

if you are trying to send a file

files = {'request_file': open('request.json', 'rb')}
r = requests.post(url, files=files)
print r.text, print r.json

ahh thanks @LukasGraf now i better understand what his original code is doing

import requests,json
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
my_json_data = json.load(open("request.json"))
req = requests.post(url,data=my_json_data)
print req.text
print 
print req.json # maybe? 

If you can use jQuery, you can try BgSwitcher plugin to switch the background-image with effects, it's very easy to use.

For example :

$('.bgSwitch').bgswitcher({
        images: ["style/img/bg0.jpg","style/img/bg1.jpg","style/img/bg2.jpg"],
        effect: "fade",
        interval: 10000
});

And add your own effect, see adding an effect types

Listing and Switching Databases in PostgreSQL When you need to change between databases, you’ll use the \connect command, or \c followed by the database name as shown below:

postgres=# \connect database_name
postgres=# \c database_name

Check the database you are currently connected to.

SELECT current_database();

PostgreSQL List Databases

postgres=# \l
 postgres=# \list

This is an old post but I was looking for an answer and I found this: https://gifs.com. Just upload the video, then it creates a gif we can add easily in a github markdown. I tried it, the quality of the gif is a good one.
