Programs & Examples On #Scheduling

I am using kue: https://github.com/learnboost/kue . It is pretty nice.

The official features and my comments:

1. delayed jobs.
   • If you want to let the job run at a specific time, calculate the milliseconds between that time and now. Call job.delay(milliseconds) (The doc says minutes, which is wrong.) Don't forget to add "jobs.promote();" when you init jobs.
2. job event and progress pubsub.
   • I don't understand it.
3. rich integrated UI.
   • Very useful. You can check the job status (done, running, delayed) in integrated UI and don't need to write any code. And you can delete old records in UI.
4. infinite scrolling
   • Sometimes not working. Have to refresh.
5. UI progress indication
   • Good for the time-consuming jobs.
6. job specific logging
   • Because they are delayed jobs, you should log useful info in the job and check later through UI.
7. powered by Redis
   • Very useful. When you restart your node.js app, all job records are still there and the scheduled jobs will execute too!
8. optional retries
   • Nice.
9. full-text search capabilities
   • Good.
10. RESTful JSON API
    • Sound good, but I never use it.

Edit:

1. kue is not a cron like library.
2. By default kue does not supports job which runs repeatedly (e.g. every Sunday).

Zcron is available free for personal use.

Gantt chart is wrong... First process P3 has arrived so it will execute first. Since the burst time of P3 is 3sec after the completion of P3, processes P2,P4, and P5 has been arrived. Among P2,P4, and P5 the shortest burst time is 1sec for P2, so P2 will execute next. Then P4 and P5. At last P1 will be executed.

Gantt chart for this ques will be:

| P3 | P2 | P4 | P5 | P1 |

1    4    5    7   11   14

Average waiting time=(0+2+2+3+3)/5=2

Average Turnaround time=(3+3+4+7+6)/5=4.6

A daily task? Sounds like it should just be a scheduled task (control panel) - no need for a service here.

The Linux Kernel does not automatically change the IO Scheduler at run-time. By this I mean, the Linux kernel, as of today, is not able to automatically choose an "optimal" scheduler depending on the type of secondary storage devise. During start-up, or during run-time, it is possible to change the IO scheduler manually.

The default scheduler is chosen at start-up based on the contents in the file located at /linux-2.6 /block/Kconfig.iosched. However, it is possible to change the IO scheduler during run-time by echoing a valid scheduler name into the file located at /sys/block/[DEV]/queue/scheduler. For example, echo deadline > /sys/block/hda/queue/scheduler

If it's available to you, then it's difficult to think of a reason not to use the Java 5 executor framework. Calling:

ScheduledExecutorService ex = Executors.newSingleThreadScheduledExecutor();

will give you a ScheduledExecutorService with similar functionality to Timer (i.e. it will be single-threaded) but whose access may be slightly more scalable (under the hood, it uses concurrent structures rather than complete synchronization as with the Timer class). Using a ScheduledExecutorService also gives you advantages such as:

• You can customize it if need be (see the newScheduledThreadPoolExecutor() or the ScheduledThreadPoolExecutor class)
• The 'one off' executions can return results

About the only reasons for sticking to Timer I can think of are:

• It is available pre Java 5
• A similar class is provided in J2ME, which could make porting your application easier (but it wouldn't be terribly difficult to add a common layer of abstraction in this case)

In Workbook events:

Private Sub Workbook_Open()
    RunEveryTwoMinutes
End Sub

In a module:

Sub RunEveryTwoMinutes()
    //Add code here for whatever you want to happen
    Application.OnTime Now + TimeValue("00:02:00"), "RunEveryTwoMinutes"
End Sub

If you only want the first piece of code to execute after the workbook opens then just add a delay of 2 minutes into the Workbook_Open event

These days, you can leverage the .NET library from VBA. The following works for me in Excel 2016. Returns the hash as uppercase hex.

Public Function SHA1(ByVal s As String) As String
    Dim Enc As Object, Prov As Object
    Dim Hash() As Byte, i As Integer

    Set Enc = CreateObject("System.Text.UTF8Encoding")
    Set Prov = CreateObject("System.Security.Cryptography.SHA1CryptoServiceProvider")

    Hash = Prov.ComputeHash_2(Enc.GetBytes_4(s))

    SHA1 = ""
    For i = LBound(Hash) To UBound(Hash)
        SHA1 = SHA1 & Hex(Hash(i) \ 16) & Hex(Hash(i) Mod 16)
    Next
End Function

If you are not limited to using ftplib you can also give wget module a try. Here, is the snippet

import wget
file_loc = 'http://www.website.com/foo.zip'
wget.download(file_loc)

The display:table family of CSS properties is mostly there so that HTML tables can be defined in terms of them. Because they're so intimately linked to a specific tag structure, they don't see much use beyond that.

If you were going to use these properties in your page, you would need a tag structure that closely mimicked that of tables, even though you weren't actually using the <table> family of tags. A minimal version would be a single container element (display:table), with direct children that can all be represented as rows (display:table-row), which themselves have direct children that can all be represented as cells (display:table-cell). There are other properties that let you mimic other tags in the table family, but they require analogous structures in the HTML. Without this, it's going to be very hard (if not impossible) to make good use of these properties.

var x = document.getElementsByClassName("class name");
if (x[0]) {
alert('has');
} else {
alert('no has');
}

Try this one:

class test {
     public function newTest(){
          $this->bigTest();
          $this->smallTest();
     }

     private function bigTest(){
          //Big Test Here
     }

     private function smallTest(){
          //Small Test Here
     }

     public function scoreTest(){
          //Scoring code here;
     }
}

$testObject = new test();

$testObject->newTest();

$testObject->scoreTest();

If you want a default notification sound to be played, then you can use setDefaults(int) method of NotificationCompat.Builder class:

NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_notification)
                .setContentTitle(getString(R.string.app_name))
                .setContentText(someText)
                .setDefaults(Notification.DEFAULT_SOUND)
                .setAutoCancel(true);

I believe that's the easiest way to accomplish your task.

Here is my method to cast an object but not to a generic type variable, rather to a System.Type dynamically:

I create a lambda expression at run-time using System.Linq.Expressions, of type Func<object, object>, that unboxes its input, performs the desired type conversion then gives the result boxed. A new one is needed not only for all types that get casted to, but also for the types that get casted (because of the unboxing step). Creating these expressions is highly time consuming, because of the reflection, the compilation and the dynamic method building that is done under the hood. Luckily once created, the expressions can be invoked repeatedly and without high overhead, so I cache each one.

private static Func<object, object> MakeCastDelegate(Type from, Type to)
{
    var p = Expression.Parameter(typeof(object)); //do not inline
    return Expression.Lambda<Func<object, object>>(
        Expression.Convert(Expression.ConvertChecked(Expression.Convert(p, from), to), typeof(object)),
        p).Compile();
}

private static readonly Dictionary<Tuple<Type, Type>, Func<object, object>> CastCache
= new Dictionary<Tuple<Type, Type>, Func<object, object>>();

public static Func<object, object> GetCastDelegate(Type from, Type to)
{
    lock (CastCache)
    {
        var key = new Tuple<Type, Type>(from, to);
        Func<object, object> cast_delegate;
        if (!CastCache.TryGetValue(key, out cast_delegate))
        {
            cast_delegate = MakeCastDelegate(from, to);
            CastCache.Add(key, cast_delegate);
        }
        return cast_delegate;
    }
}

public static object Cast(Type t, object o)
{
    return GetCastDelegate(o.GetType(), t).Invoke(o);
}

Note that this isn't magic. Casting doesn't occur in code, as it does with the dynamic keyword, only the underlying data of the object gets converted. At compile-time we are still left to painstakingly figure out exactly what type our object might be, making this solution impractical. I wrote this as a hack to invoke conversion operators defined by arbitrary types, but maybe somebody out there can find a better use case.

This is not shorter, but it deals with detached branches as well:

git branch | awk -v FS=' ' '/\*/{print $NF}' | sed 's|[()]||g'

The answer is "no, you probably can't".

While there is stuff in there that might say who created a given object, there are a lot of "ifs" behind them. A quick (and not necessarily complete) review:

sys.objects (and thus sys.tables, sys.procedures, sys.views, etc.) has column principal_id. This value is a foreign key that relates to the list of database users, which in turn can be joined with the list of SQL (instance) logins. (All of this info can be found in further system views.)

But.

A quick check on our setup here and a cursory review of BOL indicates that this value is only set (i.e. not null) if it is "different from the schema owner". In our development system, and we've got dbo + two other schemas, everything comes up as NULL. This is probably because everyone has dbo rights within these databases.

This is using NT authentication. SQL authentication probably works much the same. Also, does everyone have and use a unique login, or are they shared? If you have employee turnover and domain (or SQL) logins get dropped, once again the data may not be there or may be incomplete.

You can look this data over (select * from sys.objects), but if principal_id is null, you are probably out of luck.

You can also user java Regular Expression. String.split() also uses the expression internally. Refer http://download.oracle.com/javase/1.4.2/docs/api/java/util/regex/Pattern.html

At first install Pillow with

pip install Pillow

or as follows

c:\Python35>python -m pip install Pillow

Then in python code you may call

from PIL import Image

"Pillow is a fork of PIL, the Python Imaging Library, which is no longer maintained. However, to maintain backwards compatibility, the old module name is used." From pillow installed, but "no module named pillow" - python2.7 - Windows 7 - python -m install pillow

If a variable is not set then it is NULL and if you try to divide something by null you will get a divides by zero error

There is a rails plugin called Annotate models, that will generate your model attributes on the top of your model files here is the link:

https://github.com/ctran/annotate_models

to keep the annotation in sync, you can write a task to re-generate annotate models after each deploy.

Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.

UPD 19.03.2019 Here is a version for browser on GitHub.

I hunted around for ages to find a decent easy solution to this and in the end found some ridiculously complicated CLR solutions so decided to write my own simple VB one. Simply create a new VB CLR project from the Database tab under Installed Templates, and then add a new SQL CLR VB User Defined Function. I renamed it to CLRGetFilesInDir.vb. Here's the code inside it...

Imports System
Imports System.Data
Imports System.Data.Sql
Imports System.Data.SqlTypes
Imports Microsoft.SqlServer.Server
Imports System.IO
-----------------------------------------------------------------------------
Public Class CLRFilesInDir
-----------------------------------------------------------------------------
<SqlFunction(FillRowMethodName:="FillRowFiles", IsDeterministic:=True, IsPrecise:=True, TableDefinition:="FilePath nvarchar(4000)")> _
Public Shared Function GetFiles(PathName As SqlString, Pattern As SqlString) As IEnumerable
    Dim FileNames As String()

    Try
    FileNames = Directory.GetFiles(PathName, Pattern, SearchOption.TopDirectoryOnly)
    Catch
        FileNames = Nothing
    End Try

    Return FileNames

End Function
-----------------------------------------------------------------------------
Public Shared Sub FillRowFiles(ByVal obj As Object, ByRef Val As SqlString)
    Val = CType(obj, String).ToString
End Sub

End Class

I also changed the Assembly Name in the Project Properties window to CLRExcelFiles, and the Default Namespace to CLRGetExcelFiles.

NOTE: Set the target framework to 3.5 if you are using anything less that SQL Server 2012.

Compile the project and then copy the CLRExcelFiles.dll from \bin\release to somewhere like C:\temp on the SQL Server machine, not your own.

In SSMS:-

CREATE ASSEMBLY <your assembly name in here - anything you like>
FROM 'C:\temp\CLRExcelFiles.dll';

CREATE FUNCTION dbo.fnGetFiles
(
@PathName NVARCHAR(MAX),
@Pattern NVARCHAR(MAX)
)
RETURNS TABLE (Val NVARCHAR(100))
AS
EXTERNAL NAME <your assembly name>."CLRGetExcelFiles.CLRFilesInDir".GetFiles;
GO

then call it

SELECT * FROM dbo.fnGetFiles('\\<SERVERNAME>\<$SHARE>\<folder>\' , '*.xls')

NOTE: Even though I changed the Permission Level to EXTERNAL_ACCESS on the SQLCLR tab under Project Properties, I still needed to run this every time I (re)created it.

ALTER ASSEMBLY [CLRFilesInDirAssembly] 
WITH PERMISSION_SET = EXTERNAL_ACCESS 
GO

and wullah! that should work.

Add a label control to your Repeater's ItemTemplate. Handle OnItemCreated event.

ASPX

<asp:Repeater ID="rptr" runat="server" OnItemCreated="RepeaterItemCreated">
    <ItemTemplate>
        <div id="width:50%;height:30px;background:#0f0a0f;">
            <asp:Label ID="lblSr" runat="server" 
               style="width:30%;float:left;text-align:right;text-indent:-2px;" />
            <span 
               style="width:65%;float:right;text-align:left;text-indent:-2px;" >
            <%# Eval("Item") %>
            </span>
        </div>
    </ItemTemplate>
</asp:Repeater>

Code Behind:

    protected void RepeaterItemCreated(object sender, RepeaterItemEventArgs e)
    {
        Label l = e.Item.FindControl("lblSr") as Label;
        if (l != null)
            l.Text = e.Item.ItemIndex + 1+"";
    }

You can use the pgrep command like in the following example

$ pgrep Keychain\ Access
44186

You can also use -S, -D or -P which are equivalent of saving the package to an app dependency, a dev dependency or prod dependency. See more NPM shortcuts below:

-v: --version
-h, -?, --help, -H: --usage
-s, --silent: --loglevel silent
-q, --quiet: --loglevel warn
-d: --loglevel info
-dd, --verbose: --loglevel verbose
-ddd: --loglevel silly
-g: --global
-C: --prefix
-l: --long
-m: --message
-p, --porcelain: --parseable
-reg: --registry
-f: --force
-desc: --description
-S: --save
-P: --save-prod
-D: --save-dev
-O: --save-optional
-B: --save-bundle
-E: --save-exact
-y: --yes
-n: --yes false
ll and la commands: ls --long

This list of shortcuts can be obtained by running the following command:

$ npm help 7 config

For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.

The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)

Using this regex:

^(?!.*function).*(\&\$)

it is possible to search project-wide for the occurrence of &$ only in lines that are not a function definition.

This still turns up a lot of false positives, but it does make the job easier.

VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.

In my case, the file ~/.curlrc had a wrong proxy configured.

Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.

However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown event to block key input before it displays on the screen.

Font.Name, Font.XYZProperty, etc are readonly as Font is an immutable object, so you need to specify a new Font object to replace it:

mainForm.lblName.Font = new Font("Arial", mainForm.lblName.Font.Size);

Check the constructor of the Font class for further options.

If you want a way to iterate the item pairs of a dictionary that works with both Python 2 and 3, try something like this:

DICT_ITER_ITEMS = (lambda d: d.iteritems()) if hasattr(dict, 'iteritems') else (lambda d: iter(d.items()))

Use it like this:

for key, value in DICT_ITER_ITEMS(myDict):
    # Do something with 'key' and/or 'value'.

Simple solution: In AndroidManifest in Activity tag use

android:windowSoftInputMode="stateAlwaysHidden"

WRITING TO BUFFER

if you write to a 4 byte buffer, symbol ? with UTF8 encoding, your binary will look like this:

00000000 11100011 10000001 10000010

if you write to a 4 byte buffer, symbol ? with UTF16 encoding, your binary will look like this:

00000000 00000000 00110000 01000010

As you can see, depending on what language you would use in your content this will effect your memory accordingly.

e.g. For this particular symbol: ? UTF16 encoding is more efficient since we have 2 spare bytes to use for the next symbol. But it doesn't mean that you must use UTF16 for Japan alphabet.

READING FROM BUFFER

Now if you want to read the above bytes, you have to know in what encoding it was written to and decode it back correctly.

e.g. If you decode this : 00000000 11100011 10000001 10000010 into UTF16 encoding, you will end up with ? not ?

Note: Encoding and Unicode are two different things. Unicode is the big (table) with each symbol mapped to a unique code point. e.g. ? symbol (letter) has a (code point): 30 42 (hex). Encoding on the other hand, is an algorithm that converts symbols to more appropriate way, when storing to hardware.

30 42 (hex) - > UTF8 encoding - > E3 81 82 (hex), which is above result in binary.

30 42 (hex) - > UTF16 encoding - > 30 42 (hex), which is above result in binary.

It does this by default, you just need to look into the project's /dist folder.

VBA functions treat the function name itself as a sort of variable. So instead of using a "return" statement, you would just say:

test = 1

Notice, though, that this does not break out of the function. Any code after this statement will also be executed. Thus, you can have many assignment statements that assign different values to test, and whatever the value is when you reach the end of the function will be the value returned.

You have to use escaping of characters. It's a solution of this chicken-and-egg problem: how do I write a ", if I need it to terminate a string literal? So, the C creators decided to use a special character that changes treatment of the next char:

printf("this is a \"quoted string\"");

Also you can use '\' to input special symbols like "\n", "\t", "\a", to input '\' itself: "\\" and so on.

This is jQuery Email Validation using Regex Expression. you can also use the same concept for AngularJS if you have idea of AngularJS.

var expression = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/;

This minimal CMakeLists.txt file compiles a simple shared library:

cmake_minimum_required(VERSION 2.8)

project (test)
set(CMAKE_BUILD_TYPE Release)

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
add_library(test SHARED src/test.cpp)

However, I have no experience copying files to a different destination with CMake. The file command with the COPY/INSTALL signature looks like it might be useful.

This is something I have done in the past. Create a list of objects, and you can then have objects delete themselves with the list.remove() method.

bullet_list = []

class Bullet:
    def kill_self(self):
        bullet_list.remove(self)

bullet_list += [Bullet()]

The second is preferred because it is far less likely to result in an accidental cross join by forgetting to put inthe where clause. A join with no on clause will fail the syntax check, an old style join with no where clause will not fail, it will do a cross join.

Additionally when you later have to a left join, it is helpful for maintenance that they all be in the same structure. And the old syntax has been out of date since 1992, it is well past time to stop using it.

Plus I have found that many people who exclusively use the first syntax don't really understand joins and understanding joins is critical to getting correct results when querying.

Your question is a little unclear. If you're generating hostDict in a loop:

with open('data.txt', 'a') as outfile:
    for hostDict in ....:
        json.dump(hostDict, outfile)
        outfile.write('\n')

If you mean you want each variable within hostDict to be on a new line:

with open('data.txt', 'a') as outfile:
    json.dump(hostDict, outfile, indent=2)

When the indent keyword argument is set it automatically adds newlines.

['class' => 'yii\db\Connection',
    'dsn' => 'mysql:host=localhost:3306;dbname=testdb',
    'username' => 'user',
    'password' => 'password',
    'charset' => 'utf8',]

It's simple: Just provide the port number along with the host name and set default sock path to your mysql.sock file path in php.ini which the server is running on.

Not bad variant too)

var arr = [{id: 1, name: "Person 1"}, {id: 2, name: "Person 2"}];

var id = 1; //id to find

arr[_.find(arr, {id: id})].name = 'New Person';

Is it also possible to access the management port in a similar way, e.g.:

  @SpringBootTest(classes = {Application.class}, webEnvironment = WebEnvironment.RANDOM_PORT)
  public class MyTest {

    @LocalServerPort
    int randomServerPort;

    @LocalManagementPort
    int randomManagementPort;

A simple solution:

using (Form2 f2 = new Form2())
{
    f2.Show();
    f2.Update();

    System.Threading.Thread.Sleep(2500);
} // f2 is closed and disposed here

And then substitute your Loading for the Sleep.
This blocks the UI thread, on purpose.

You use the String.format() method.

Merging several answers from above into an easy to use function

function GetScriptIfNotLoaded(scriptLocationAndName)
{
  var len = $('script[src*="' + scriptLocationAndName +'"]').length;

  //script already loaded!
  if (len > 0)
      return;

  var head = document.getElementsByTagName('head')[0];
  var script = document.createElement('script');
  script.type = 'text/javascript';
  script.src = scriptLocationAndName;
  head.appendChild(script);
}

In the rare cases I have wanted to test private functions, I have usually modified them to be protected instead, and the I have written a subclass with a public wrapper function.

The Class:

...

protected void APrivateFunction()
{
    ...
}

...

Subclass for testing:

...

[Test]
public void TestAPrivateFunction()
{
    APrivateFunction();
    //or whatever testing code you want here
}

...

use colspan="100%" in table cell and it's working fine.

colspan="100%"

A solution that:

• outside of virtualenv - provides the path of global site-packages,
• insidue a virtualenv - provides the virtualenv's site-packages

...is this one-liner:

python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())"

Formatted for readability (rather than use as a one-liner), that looks like the following:

from distutils.sysconfig import get_python_lib
print(get_python_lib())

You may need to clear the plugin column for your root account. On my fresh install, all of the root user accounts had unix_socket set in the plugin column. This was causing the root sql account to be locked only to the root unix account, since only system root could login via socket.

If you update user set plugin='' where User='root';flush privileges;, you should now be able to login to the root account from any localhost unix account (with a password).

See this AskUbuntu question and answer for more details.

Use CAST with following parameters:

Date

select Cast('2017-10-11 14:38:50.440' as date)

Output: 2017-10-11

Datetime

select Cast('2017-10-11 14:38:50.440' as datetime)

Output: 2017-10-11 14:38:50.440

SmallDatetime

select Cast('2017-10-11 14:38:50.440' as smalldatetime)

Output: 2017-10-11 14:39:00

DatetimeOffset

select Cast('2017-10-11 14:38:50.440' as datetimeoffset)

Output: 2017-10-11 14:38:50.4400000 +00:00

Datetime2

select Cast('2017-10-11 14:38:50.440' as datetime2)

Output: 2017-10-11 14:38:50.4400000

I could not make @Clockwork-Muse work actually. But I could make this variation work:

WITH Tmp AS (SELECT * FROM (VALUES (id1, newsPosX1, newPosY1), 
                                   (id2, newsPosX2, newPosY2),
                                   ......................... ,
                                   (idN, newsPosXN, newPosYN)) d(id, px, py))

UPDATE t

SET posX = (SELECT px FROM Tmp WHERE t.id = Tmp.id),
    posY = (SELECT py FROM Tmp WHERE t.id = Tmp.id)

FROM TableToUpdate t

I hope this works for you too!

Adding a branch option in .gitmodule is NOT related to the detached behavior of submodules at all. The old answer from @mkungla is incorrect, or obsolete.

From git submodule --help, HEAD detached is the default behavior of git submodule update --remote.

First, there's no need to specify a branch to be tracked. origin/master is the default branch to be tracked.

--remote

Instead of using the superproject's recorded SHA-1 to update the submodule, use the status of the submodule's remote-tracking branch. The remote used is branch's remote (branch.<name>.remote), defaulting to origin. The remote branch used defaults to master.

Why

So why is HEAD detached after update? This is caused by the default module update behavior: checkout.

--checkout

Checkout the commit recorded in the superproject on a detached HEAD in the submodule. This is the default behavior, the main use of this option is to override submodule.$name.update when set to a value other than checkout.

To explain this weird update behavior, we need to understand how do submodules work?

Quote from Starting with Submodules in book Pro Git

Although sbmodule DbConnector is a subdirectory in your working directory, Git sees it as a submodule and doesn’t track its contents when you’re not in that directory. Instead, Git sees it as a particular commit from that repository.

The main repo tracks the submodule with its state at a specific point, the commit id. So when you update modules, you're updating the commit id to a new one.

How

If you want the submodule merged with remote branch automatically, use --merge or --rebase.

--merge

This option is only valid for the update command. Merge the commit recorded in the superproject into the current branch of the submodule. If this option is given, the submodule's HEAD will not be detached.

--rebase

Rebase the current branch onto the commit recorded in the superproject. If this option is given, the submodule's HEAD will not be detached.

All you need to do is,

git submodule update --remote --merge
# or
git submodule update --remote --rebase

Recommended alias:

git config alias.supdate 'submodule update --remote --merge'

# do submodule update with
git supdate

There's also an option to make --merge or --rebase as the default behavior of git submodule update, by setting submodule.$name.update to merge or rebase.

Here's an example about how to config the default update behavior of submodule update in .gitmodule.

[submodule "bash/plugins/dircolors-solarized"]
    path = bash/plugins/dircolors-solarized
    url = https://github.com/seebi/dircolors-solarized.git
    update = merge # <-- this is what you need to add

Or configure it in command line,

# replace $name with a real submodule name
git config -f .gitmodules submodule.$name.update merge

This question has been answered already several times, I'll short summary for each of them, an example and insights as of September 2019:

• Normalize.css - as the name suggests, it normalizes styles in the browsers for their user agents, i.e. makes them the same across all browsers due to the reason by default they're slightly different.

Example: <h1> tag inside <section> by default Google Chrome will make smaller than the "expected" size of <h1> tag. Microsoft Edge on the other hand is making the "expected" size of <h1> tag. Normalize.css will make it consistent.

Current status: the npm repository shows that normalize.css package has currently more than 500k downloads per week. GitHub stars in the project of the repository are more than 36k.

• Reset CSS - as the name suggests, it resets all styles, i.e. it removes all browser's user agent styles.

Example: it would do something like that below:

html, body, div, span, ..., audio, video {  
   margin: 0;  
   padding: 0;  
   border: 0;  
   font-size: 100%;  
   font: inherit;  
   vertical-align: baseline; 
}

Current status: it's much less popular than Normalize.css, the reset-css package shows it's something around 26k downloads per week. GitHub stars are only 200, as it can be noticed from the project's repository.

Short answer: Don't do it.

Longer answer: Use WCF. It's here to replace Asmx.

see this answer for example, or the first comment on this one.

John Saunders: ASMX is a legacy technology, and should not be used for new development. WCF or ASP.NET Web API should be used for all new development of web service clients and servers. One hint: Microsoft has retired the ASMX Forum on MSDN.

As for comment ... well, if you have to, you have to. I'll leave you in the competent hands of the other answers then. (Even though it's funny it has issues, and if it does, why are you doing it in VS2013 to begin with ?)

this should work:

setw -g mode-mouse on

then resource then config file

tmux source-file ~/.tmux.conf

or kill the server

You might want to take a look at the timeit module:

http://docs.python.org/library/timeit.html

or the profile module:

http://docs.python.org/library/profile.html

There are some additionally some nice tutorials here:

http://www.doughellmann.com/PyMOTW/profile/index.html

http://www.doughellmann.com/PyMOTW/timeit/index.html

And the time module also might come in handy, although I prefer the later two recommendations for benchmarking and profiling code performance:

Python string parsing walkthrough

Split a string on space, get a list, show its type, print it out:

el@apollo:~/foo$ python
>>> mystring = "What does the fox say?"

>>> mylist = mystring.split(" ")

>>> print type(mylist)
<type 'list'>

>>> print mylist
['What', 'does', 'the', 'fox', 'say?']

If you have two delimiters next to each other, empty string is assumed:

el@apollo:~/foo$ python
>>> mystring = "its  so   fluffy   im gonna    DIE!!!"

>>> print mystring.split(" ")
['its', '', 'so', '', '', 'fluffy', '', '', 'im', 'gonna', '', '', '', 'DIE!!!']

Split a string on underscore and grab the 5th item in the list:

el@apollo:~/foo$ python
>>> mystring = "Time_to_fire_up_Kowalski's_Nuclear_reactor."

>>> mystring.split("_")[4]
"Kowalski's"

Collapse multiple spaces into one

el@apollo:~/foo$ python
>>> mystring = 'collapse    these       spaces'

>>> mycollapsedstring = ' '.join(mystring.split())

>>> print mycollapsedstring.split(' ')
['collapse', 'these', 'spaces']

When you pass no parameter to Python's split method, the documentation states: "runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace".

Hold onto your hats boys, parse on a regular expression:

el@apollo:~/foo$ python
>>> mystring = 'zzzzzzabczzzzzzdefzzzzzzzzzghizzzzzzzzzzzz'
>>> import re
>>> mylist = re.split("[a-m]+", mystring)
>>> print mylist
['zzzzzz', 'zzzzzz', 'zzzzzzzzz', 'zzzzzzzzzzzz']

The regular expression "[a-m]+" means the lowercase letters a through m that occur one or more times are matched as a delimiter. re is a library to be imported.

Or if you want to chomp the items one at a time:

el@apollo:~/foo$ python
>>> mystring = "theres coffee in that nebula"

>>> mytuple = mystring.partition(" ")

>>> print type(mytuple)
<type 'tuple'>

>>> print mytuple
('theres', ' ', 'coffee in that nebula')

>>> print mytuple[0]
theres

>>> print mytuple[2]
coffee in that nebula

I often use this workaround in CLI where instead of configuring my .gitignore, I create a separate .include file where I define the (sub)directories I want included in spite of directories directly or recursively ignored by .gitignore.

Thus, I additionally use

git add `cat .include`

during staging, before committing.

To the OP, I suggest using a .include which has these lines:

<parent_folder_path>/application/language/gr/*

NOTE: Using cat does not allow usage of aliases (within .include) for specifying $HOME (or any other specific directory). This is because the line homedir/app1/* when passed to git add using the above command appears as git add 'homedir/app1/*', and enclosing characters in single quotes ('') preserves the literal value of each character within the quotes, thus preventing aliases (such as homedir) from functioning (see Bash Single Quotes).

Here is an example of a .include file I use in my repo here.

/home/abhirup/token.txt
/home/abhirup/.include
/home/abhirup/.vim/*
/home/abhirup/.viminfo
/home/abhirup/.bashrc
/home/abhirup/.vimrc
/home/abhirup/.condarc

My worry is if I say delete evertything with an ID (>79 AND < 296) then it may literally wipe the whole table...

That wont happen because you will have a where clause. What happens is that, if you have a statement like delete * from Table1 where id between 70 and 1296 , the first thing that sql query processor will do is to scan the table and look for those records in that range and then apply a delete.

For Finding All the ChildNodes you can use the below Snippet

List<WebElement> childs = MyCurrentWebElement.findElements(By.xpath("./child::*"));

        for (WebElement e  : childs)
        {
            System.out.println(e.getTagName());
        }

Note that this will give all the Child Nodes at same level -> Like if you have structure like this :

<Html> 
<body> 
 <div> ---suppose this is current WebElement 
   <a>
   <a>
      <img>
          <a>
      <img>
   <a>

It will give me tag names of 3 anchor tags here only . If you want all the child Elements recursively , you can replace the above code with MyCurrentWebElement.findElements(By.xpath(".//*"));

Hope That Helps !!

Well you seem to have mistaken them both for what they do.

$(window).height() gets you an unit-less pixel value of the height of the (browser) window aka viewport. With respect to the web browsers the viewport here is visible portion of the canvas(which often is smaller than the document being rendered).

$(document).height() returns an unit-less pixel value of the height of the document being rendered. However, if the actual document’s body height is less than the viewport height then it will return the viewport height instead.

Hope that clears things a little.

generateNumbers() expects a parameter and you aren't passing one in!

generateNumbers() also returns after it has set the first random number - seems to be some confusion about what it is trying to do.

You could simply add some random number with the CSS and JavaScript URL like

example.css?randomNo = Math.random()

struct node{
    int position;
    char name[30];
    struct node * next;
};

void free_list(node * list){
    node* next_node;

    printf("\n\n Freeing List: \n");
    while(list != NULL)
    {
        next_node = list->next;
        printf("clear mem for: %s",list->name);
        free(list);
        list = next_node;
        printf("->");
    }
}

Since you have updated your label client side, you'll need a post-back in order for you're server side code to reflect the changes.

If you do not know how to do this, here is how I've gone about it in the past.

Create a hidden field:

<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />

Create a button that has both client side and server side functions attached to it. You're client side function will populate your hidden field, and the server side will read it. Be sure you're client side is being called first.

<asp:Button ID="_Submit" runat="server" Text="Submit Button" OnClientClick="TestSubmit();" OnClick="_Submit_Click" />

Javascript Client Side Function:

function TestSubmit() {
              try {

             var message = "Message to Pass";
             document.getElementById('__EVENTTARGET').value = message;

           } catch (err) {
              alert(err.message);

          }

      }

C# Server Side Function

protected void _Submit_Click(object sender, EventArgs e)
{
     // Hidden Value after postback
     string hiddenVal= Request.Form["__EVENTTARGET"];
}

Hope this helps!

i don't know what mistakes i did while implementing the above solutions, bt they were unsuccessful for me

txtDeck.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override       
    public void onFocusChange(View v, boolean hasFocus) {
        txtDeck.setText("");
    }
});

This works for me,

I use a function to echo and run the command:

#!/bin/bash
# Function to display commands
exe() { echo "\$ $@" ; "$@" ; }

exe echo hello world

Which outputs

$ echo hello world
hello world

For more complicated commands pipes, etc., you can use eval:

#!/bin/bash
# Function to display commands
exe() { echo "\$ ${@/eval/}" ; "$@" ; }

exe eval "echo 'Hello, World!' | cut -d ' ' -f1"

Which outputs

$  echo 'Hello, World!' | cut -d ' ' -f1
Hello

This seems issue with my node upgrade. How ever I solved it with the following approach.

First uninstall the cli, clear cashe, and reinstall with these commands

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli

Then install node-pre-gyp

npm install -g node-pre-gyp

Restart your terminal and see if the issue is solved.

If your jar file already has an absolute pathname as shown, it is particularly easy:

cd /where/you/want/it; jar xf /path/to/jarfile.jar

That is, you have the shell executed by Python change directory for you and then run the extraction.

If your jar file does not already have an absolute pathname, then you have to convert the relative name to absolute (by prefixing it with the path of the current directory) so that jar can find it after the change of directory.

The only issues left to worry about are things like blanks in the path names.

public static class Employee
{
    public static string SomeSetting
    {
        get 
        {
            return ConfigurationManager.AppSettings["SomeSetting"];    
        }
    }
}

Declare the property as static, as well. Also, Don't bother storing a private reference to ConfigurationManager.AppSettings. ConfigurationManager is already a static class.

If you feel that you must store a reference to appsettings, try

public static class Employee
{
    private static NameValueCollection _appSettings=ConfigurationManager.AppSettings;

    public static NameValueCollection AppSettings { get { return _appSettings; } }

}

It's good form to always give an explicit access specifier (private, public, etc) even though the default is private.

Once you have both branches in one repository you can do a git diff. And getting them in one repository is as easy as

git fetch /the/other/repo/.git refs/heads/*:refs/remotes/other/*

If you have query like:

SELECT * FROM user WHERE id IN (1, 2, 3, 4 -- and thousands of another keys)

you may increase performace if rewrite your query like:

SELECT * FROM user WHERE id = ANY(VALUES (1), (2), (3), (4) -- and thousands of another keys)

Refer to here

write query with named parameter, use simple ListPreparedStatementSetter with all parameters in sequence. Just add below snippet to convert the query in traditional form based to available parameters,

ParsedSql parsedSql = NamedParameterUtils.parseSqlStatement(namedSql);

List<Integer> parameters = new ArrayList<Integer>();
for (A a : paramBeans)
    parameters.add(a.getId());

MapSqlParameterSource parameterSource = new MapSqlParameterSource();
parameterSource.addValue("placeholder1", parameters);
// create SQL with ?'s
String sql = NamedParameterUtils.substituteNamedParameters(parsedSql, parameterSource);     
return sql;

Left shift <<

This is somehow easy and whenever you use the shift operator, it is always a bit-wise operation, so we can't use it with a double and float operation. Whenever we left shift one zero, it is always added to the least significant bit (LSB).

But in right shift >> we have to follow one additional rule and that rule is called "sign bit copy". Meaning of "sign bit copy" is if the most significant bit (MSB) is set then after a right shift again the MSB will be set if it was reset then it is again reset, means if the previous value was zero then after shifting again, the bit is zero if the previous bit was one then after the shift it is again one. This rule is not applicable for a left shift.

The most important example on right shift if you shift any negative number to right shift, then after some shifting the value finally reach to zero and then after this if shift this -1 any number of times the value will remain same. Please check.

I think you meant to do url[i] <- paste(...

instead of url[i] = paste(.... If so replace = with <-.

There are several ways. One way is to use save() to save the exact object. e.g. for data frame foo:

save(foo,file="data.Rda")

Then load it with:

load("data.Rda")

You could also use write.table() or something like that to save the table in plain text, or dput() to obtain R code to reproduce the table.

For start Activity 2 from Activity 1 and get result, you could use startActivityForResult and implement onActivityResult in Activity 1 and use setResult in Activity2.

Intent intent = new Intent(this, Activity2.class);
intent.putExtra(NUMERO1, numero1);
intent.putExtra(NUMERO2, numero2);
//startActivity(intent);
startActivityForResult(intent, MI_REQUEST_CODE);

Correción: 3-LEN

declare @t  TINYINT 
set @t =233
SELECT ISNULL(REPLICATE('0',3-LEN(@t)),'') + CAST(@t AS VARCHAR) 

This is very straightforward with boolean arrays:

p31 = numpy.asarray(o31)
za = (p31 < 200).sum() # p31<200 is a boolean array, so `sum` counts the number of True elements

I've resolved wiping data from AVD Manager

You have to wait for TypeScript 2.0 with async/await for ES5 support as it now supported only for TS to ES6 compilation.

You would be able to create delay function with async:

function delay(ms: number) {
    return new Promise( resolve => setTimeout(resolve, ms) );
}

And call it

await delay(300);

Please note, that you can use await only inside async function.

If you can't (let's say you are building nodejs application), just place your code in the anonymous async function. Here is an example:

    (async () => { 
        // Do something before delay
        console.log('before delay')

        await delay(1000);

        // Do something after
        console.log('after delay')
    })();

Example TS Application: https://github.com/v-andrew/ts-template

In OLD JS you have to use

setTimeout(YourFunctionName, Milliseconds);

or

setTimeout( () => { /*Your Code*/ }, Milliseconds );

However with every major browser supporting async/await it less useful.

Update: TypeScript 2.1 is here with async/await.

Just do not forget that you need Promise implementation when you compile to ES5, where Promise is not natively available.

PS

You have to export the function if you want to use it outside of the original file.

EDIT

another way to deal with duplicate is you can do like this

var dic = slist.Select((element, index)=> new{element,index} )
            .ToDictionary(ele=>ele.index.ToString(), ele=>ele.element);

or

easy way to do is

var res = list.ToDictionary(str => str, str=> str); 

but make sure that there is no string is repeating...again otherewise above code will not work for you

if there is string is repeating than its better to do like this

Dictionary<string,string> dic= new Dictionary<string,string> ();

    foreach(string s in Stringlist)
    {
       if(!dic.ContainsKey(s))
       {
        //  dic.Add( value to dictionary
      }
    }

Okay I fixed this thing. Had to first convert the projects to Maven Projects, then remove them from the Eclipse workspace, and then re-import them.

Yes, we can use jQuery in ReactJs. Here I will tell how we can use it using npm.

step 1: Go to your project folder where the package.json file is present via using terminal using cd command.

step 2: Write the following command to install jquery using npm : npm install jquery --save

step 3: Now, import $ from jquery into your jsx file where you need to use.

Example:

write the below in index.jsx

import React from 'react';
import ReactDOM from 'react-dom';
import $ from 'jquery';


//   react code here


$("button").click(function(){
    $.get("demo_test.asp", function(data, status){
        alert("Data: " + data + "\nStatus: " + status);
    });
});

// react code here

write the below in index.html

<!DOCTYPE html>
<html>
<head>
    <script src="index.jsx"></script>
    <!-- other scripting files -->
</head>
<body>
    <!-- other useful tags -->
    <div id="div1">
        <h2>Let jQuery AJAX Change This Text</h2>
    </div>
    <button>Get External Content</button>
</body>
</html>

This code is working for me either paste from right click or direct copy paste

   $('.textbox').on('paste input propertychange', function (e) {
        $(this).val( $(this).val().replace(/[^0-9.]/g, '') );
    })

When i paste Section 1: Labour Cost it becomes 1 in text box.

To allow only float value i use this code

 //only decimal
    $('.textbox').keypress(function(e) {
        if(e.which == 46 && $(this).val().indexOf('.') != -1) {
            e.preventDefault();
        } 
       if (e.which == 8 || e.which == 46) {
            return true;
       } else if ( e.which < 48 || e.which > 57) {
            e.preventDefault();
      }
    });

You can try something like this.

<button class="button" ng-disabled="(!data.var1 && !data.var2) ? false : true">
</button>

Its working fine for me.

According to Harry's linear-gradient solution (answered Oct 14 '15 at 9:55), it says that opacity background isn't possible, I tried it and yep, it isn't.

But! I found a workaround. No it's not super optimised, but it worked. So here's my solution. Since Harry doesn't use pseudo element, we can achieve this by creating one.

Set position relative to the container and create a pseudo element with the same linear-gradient properties. In other words, just clone it. Then put a transparent background for the container, and lets say a black background for the clone. Put a position absolute on it, a z-index of -1 and an opacity value (ie. 50%). It will do the job. Again it's a workaround and it's not perfect but it works just fine.

Deploying Angular 2 in azure is easy

1. Run ng build --prod , which will generate a dist folder with everything bundled inside few files including index.html.

2. Create a resource group and a web app inside it.

3. Place your dist folders files using FTP. In azure it will look for index.html to the run the application.

That's it. Your app is running !

If you're using Homebrew /usr/local/bin should already be at the front of $PATH or at least come before /usr/bin. If you now run brew link --force openssl in your terminal window, open a new one and run which openssl in it. It should now show openssl under /usr/local/bin.

This is an ancient question, but both module private (one underscore) and class-private (two underscores) mangled variables are now covered in the standard documentation:

The Python Tutorial » Classes » Private Variables

Usually a video stream is somewhat fault tolerant. So if some packages get lost (due to some router along the way being overloaded, for example), then it will still be able to display the content, but with reduced quality.

If your live stream was using TCP/IP, then it would be forced to wait for those dropped packages before it could continue processing newer data.

That's doubly bad:

• old data be re-transmitted (that's probably for a frame that was already displayed and therefore worthless) and
• new data can't arrive until after old data was re-transmitted

If your goal is to display as up-to-date information as possible (and for a live-stream you usually want to be up-to-date, even if your frames look a bit worse), then TCP will work against you.

For a recorded stream the situation is slightly different: you'll probably be buffering a lot more (possibly several minutes!) and would rather have data re-transmitted than have some artifacts due to lost packages. In this case TCP is a good match (this could still be implemented in UDP, of course, but TCP doesn't have as much drawbacks as for the live stream case).

Can't think of a only css solution, but couldn't you just had a div between those 2 and set in the css the properties to look like a line like shown in the image? If you are using divs as they were table cells this is a pretty simple solution to the problem

You can't.

The only way to get a list of all event listeners attached to a node is to intercept the listener attachment call.

DOM4 addEventListener

Says

Append an event listener to the associated list of event listeners with type set to type, listener set to listener, and capture set to capture, unless there already is an event listener in that list with the same type, listener, and capture.

Meaning that an event listener is added to the "list of event listeners". That's all. There is no notion of what this list should be nor how you should access it.

Many different ways have already been described by the other answers. However, many of them either involved ShowDialog() or that form1 stay open but hidden. The best and most intuitive way in my opinion is to simply close form1 and then create form2 from an outside location (i.e. not from within either of those forms). In the case where form1 was created in Main, form2 can simply be created using Application.Run just like form1 before. Here's an example scenario:

I need the user to enter their credentials in order for me to authenticate them somehow. Afterwards, if authentication was successful, I want to show the main application to the user. In order to accomplish this, I'm using two forms: LogingForm and MainForm. The LoginForm has a flag that determines whether authentication was successful or not. This flag is then used to decide whether to create the MainForm instance or not. Neither of these forms need to know about the other and both forms can be opened and closed gracefully. Here's the code for this:

class LoginForm : Form
{
    public bool UserSuccessfullyAuthenticated { get; private set; }

    void LoginButton_Click(object s, EventArgs e)
    {
        if(AuthenticateUser(/* ... */))
        {
            UserSuccessfullyAuthenticated = true;
            Close();
        }
    }
}

static class Program
{
    [STAThread]
    static void Main()
    {
        LoginForm loginForm = new LoginForm();
        Application.Run(loginForm);

        if(loginForm.UserSuccessfullyAuthenticated)
        {
            // MainForm is defined elsewhere
            Application.Run(new MainForm());
        }
    }
}

Just another approach if you are fine using temp tables.I have personally tested this and it will not cause any exception (even if temp table does not have any data.)

CREATE TABLE #TempTable
(
    ROWID int identity(1,1) primary key,
    HIERARCHY_ID_TO_UPDATE int,
)

--create some testing data
--INSERT INTO #TempTable VALUES(1)
--INSERT INTO #TempTable VALUES(2)
--INSERT INTO #TempTable VALUES(4)
--INSERT INTO #TempTable VALUES(6)
--INSERT INTO #TempTable VALUES(8)

DECLARE @MAXID INT, @Counter INT

SET @COUNTER = 1
SELECT @MAXID = COUNT(*) FROM #TempTable

WHILE (@COUNTER <= @MAXID)
BEGIN
    --DO THE PROCESSING HERE 
    SELECT @HIERARCHY_ID_TO_UPDATE = PT.HIERARCHY_ID_TO_UPDATE
    FROM #TempTable AS PT
    WHERE ROWID = @COUNTER

    SET @COUNTER = @COUNTER + 1
END


IF (OBJECT_ID('tempdb..#TempTable') IS NOT NULL)
BEGIN
    DROP TABLE #TempTable
END

The error message the OP is encountering is just an Eclipse feature. If you are willing to tie your code to a specific maker (and even version) of the JVM, you can effectively use method sun.reflect.Reflection.getCallerClass(). You can then compile the code outside of Eclipse or configure it not to consider this diagnostic an error.

The worse Eclipse configuration is to disable all occurrences of the error by:

Project Properties / Java Compiler / Errors/Warnings / Enable project specific settings set to checked / Deprecated and restrited API / Forbidden reference (access rules) set to Warning or Ignore.

The better Eclipse configuration is to disable a specific occurrence of the error by:

Project Properties / Java Build Path / Libraries / JRE System Library expand / Access rules: select / Edit... / Add... / Resolution: set to Discouraged or Accessible / Rule Pattern set to sun/reflect/Reflection.

Source (Py v2.7.3) for traceback.format_exception() and called/related functions helps greatly. Embarrassingly, I always forget to Read the Source. I only did so for this after searching for similar details in vain. A simple question, "How to recreate the same output as Python for an exception, with all the same details?" This would get anybody 90+% to whatever they're looking for. Frustrated, I came up with this example. I hope it helps others. (It sure helped me! ;-)

import sys, traceback

traceback_template = '''Traceback (most recent call last):
  File "%(filename)s", line %(lineno)s, in %(name)s
%(type)s: %(message)s\n''' # Skipping the "actual line" item

# Also note: we don't walk all the way through the frame stack in this example
# see hg.python.org/cpython/file/8dffb76faacc/Lib/traceback.py#l280
# (Imagine if the 1/0, below, were replaced by a call to test() which did 1/0.)

try:
    1/0
except:
    # http://docs.python.org/2/library/sys.html#sys.exc_info
    exc_type, exc_value, exc_traceback = sys.exc_info() # most recent (if any) by default

    '''
    Reason this _can_ be bad: If an (unhandled) exception happens AFTER this,
    or if we do not delete the labels on (not much) older versions of Py, the
    reference we created can linger.

    traceback.format_exc/print_exc do this very thing, BUT note this creates a
    temp scope within the function.
    '''

    traceback_details = {
                         'filename': exc_traceback.tb_frame.f_code.co_filename,
                         'lineno'  : exc_traceback.tb_lineno,
                         'name'    : exc_traceback.tb_frame.f_code.co_name,

    del(exc_type, exc_value, exc_traceback) # So we don't leave our local labels/objects dangling
    # This still isn't "completely safe", though!
    # "Best (recommended) practice: replace all exc_type, exc_value, exc_traceback

You can pass a C# Guid value directly to a SQL Stored Procedure by specifying SqlDbType.UniqueIdentifier.

Your method may look like this (provided that your only parameter is the Guid):

public static void StoreGuid(Guid guid)
{
    using (var cnx = new SqlConnection("YourDataBaseConnectionString"))
    using (var cmd = new SqlCommand {
        Connection = cnx,
        CommandType = CommandType.StoredProcedure,
        CommandText = "StoreGuid",
        Parameters = {
            new SqlParameter {
                ParameterName = "@guid",
                SqlDbType = SqlDbType.UniqueIdentifier, // right here
                Value = guid
            }
        }
    })
    {
        cnx.Open();
        cmd.ExecuteNonQuery();
    }
}

I had toolbar added in my xml. Then in my activity i was adding this statement:

setSupportActionBar(toolbar);

Removing this worked for me. I hope it helps someone.

New-style classes inherit from object and must be written as such in Python 2.2 onwards (i.e. class Classname(object): instead of class Classname:). The core change is to unify types and classes, and the nice side-effect of this is that it allows you to inherit from built-in types.

Read descrintro for more details.

Can you place the #ulId in the document prior to the ajax load (with css display: none;), or wrap it in a containing div (with css display: none;), then just load the inner html during ajax page load, that way the scroll event will be linked to the div that is already there prior to the ajax?

Then you can use:

$('#ulId').on('scroll',function(){ console.log('Event Fired'); })

obviously replacing ulId with whatever the actual id of the scrollable div is.

Then set css display: block; on the #ulId (or containing div) upon load?

Had issues using the code in the answer provided by @haynar above (wouldn't play on Chrome), and it seems that one of the more modern ways to ensure it plays is to use the video tag

Example:

<video controls="controls" width="800" height="600" 
       name="Video Name" src="http://www.myserver.com/myvideo.mov"></video>

This worked like a champ for my .mov file (generated from Keynote) in both Safari and Chrome, and is listed as supported in most modern browsers (The video tag is supported in Internet Explorer 9+, Firefox, Opera, Chrome, and Safari.)

Note: Will work in IE / etc.. if you use MP4 (Mov is not officially supported by those guys)

When you do your #includes in main.c, put the #include reference to the file that contains the referenced function at the top of the include list. e.g. Say this is main.c and your referenced function is in "SSD1306_LCD.h"

#include "SSD1306_LCD.h"    
#include "system.h"        #include <stdio.h>
#include <stdlib.h>
#include <xc.h>
#include <string.h>
#include <math.h>
#include <libpic30.h>       // http://microchip.wikidot.com/faq:74
#include <stdint.h>
#include <stdbool.h>
#include "GenericTypeDefs.h"  // This has the 'BYTE' type definition

The above will not generate the "implicit declaration of function" error, but below will-

#include "system.h"        
#include <stdio.h>
#include <stdlib.h>
#include <xc.h>
#include <string.h>
#include <math.h>
#include <libpic30.h>       // http://microchip.wikidot.com/faq:74
#include <stdint.h>
#include <stdbool.h>
#include "GenericTypeDefs.h"     // This has the 'BYTE' type definition
#include "SSD1306_LCD.h"    

Exactly the same #include list, just different order.

Well, it did for me.

You can just use Scanner to read word by word, Scanner.next() reads the next word

try {
  Scanner s = new Scanner(new File(filename));

  while (s.hasNext()) {
    System.out.println("word:" + s.next());
  }
} catch (IOException e) {
  System.out.println("Error accessing input file!");
}

After several strange errors with relative paths in connectionstring I felt the need to post this here.

When using "|DataDirectory|" or "~" you are not allowed to step up and out using "../" !

Example is using several projects accessing the same localdb file placed in one of the projects.

" ~/../other" and " |DataDirectory|/../other" will fail

Even if it is clearly written at MSDN here the errors it gave where a bit unclear so hard to find and could not find it here at SO.

Try this

#include <stdio.h>

struct context;

struct funcptrs{
  void (*func0)(struct context *ctx);
  void (*func1)(void);
};

struct context{
    struct funcptrs fps;
}; 

void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }

void getContext(struct context *con){
    con->fps.func0 = func0;  
    con->fps.func1 = func1;  
}

int main(int argc, char *argv[]){
 struct context c;
   c.fps.func0 = func0;
   c.fps.func1 = func1;
   getContext(&c);
   c.fps.func0(&c);
   getchar();
   return 0;
}

Using all built-ins..

tuple(map(sum, zip(a, b)))

Promises don't "return" values, they pass them to a callback (which you supply with .then()).

It's probably trying to say that you're supposed to do resolve(someObject); inside the promise implementation.

Then in your then code you can reference someObject to do what you want.

This is a late answer, but for completeness: it is difficult to get even close to fetching 90% all favicons.

A while ago I wrote a WordPress plugin which attempts to get closer to 100%.

This is how it works:

1. It starts by searching existing favicon repositories such as Google favicons and GetFavicons for the favicon.

2. If none of them returns an icon, the plugin attempts to get the icon itself. This involves traversing several pages on the domain.

3. The plugin then inspects the physical image file, because on some servers files get returned with the incorrect mime types.

The code is still not perfect because in the details you will find many weird situations: people have wrongly coded paths, e.g. img/favicon.ico where img is not in the root, duplicate headers in HTML output, different server responses from the head and body etc.

The core of the fetching part is here so you can reverse-engineer it, but be aware that validating the response should be done (checking image filetype, mime etc.).

I have used POI.

If you use that, keep on eye those cell formatters: create one and use it several times instead of creating each time for cell, it isa huge memory consumption difference or large data.

<%= controller.controller_name %>
#=> 'users'

#to get action name, it is the method:

# or display nicely

The characters you are reading on your screen now each have a numerical value. In the ASCII format, for example, the letter 'A' is 65, 'B' is 66, and so on. If you look at a table of characters available in ASCII you will see that it isn't much use for someone who wishes to write something in Mandarin, Arabic, or Japanese. For characters / words from those languages to be displayed we needed another system of encoding them to and from numbers stored in computer memory.

UTF-8 is just one of the encoding methods that were invented to implement this requirement. It lets you write text in all kinds of languages, so French accents will appear perfectly fine, as will text like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

If you copy and paste the above text into notepad and then try to save the file as ANSI (another format) you will receive a warning that saving in this format will lose some of the formatting. Accept it, then re-load the text file and you'll see something like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

You mean fast enumeration? You question is very unclear.

A normal for loop would look a bit like this:

unsigned int i, cnt = [someArray count];
for(i = 0; i < cnt; i++)
{ 
   // do loop stuff
   id someObject = [someArray objectAtIndex:i];
}

And a loop with fast enumeration, which is optimized by the compiler, would look like this:

for(id someObject in someArray)
{
   // do stuff with object
}

Keep in mind that you cannot change the array you are using in fast enumeration, thus no deleting nor adding when using fast enumeration

Not only can you add raw strings to matplotlib but you can also specify the font in matplotlibrc or locally with:

from matplotlib import rc

rc('font', **{'family':'serif','serif':['Palatino']})
rc('text', usetex=True)

This would change your serif latex font. You can also specify the sans-serif Helvetica like so

rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})

Other options are cursive and monospace with their respective font names. Your label would then be

fig.gca().set_xlabel(r'wavelength $5000 \AA$')

If the font doesn't supply an Angstrom symbol you can try using \mathring{A}

the ordinary way (pun intended):

String[] myStringArray=new String[EMyEnum.values().length];
for(EMyEnum e:EMyEnum.values())myStringArray[e.ordinal()]=e.toString();

Try wrapping your entire select in brackets, then running a count(*) on that

select count(*)
from
(
   select m.id
   from Monitor as m 
    inner join Monitor_Request as mr 
       on mr.Company_ID=m.Company_id   group by m.Company_id
    having COUNT(m.Monitor_id)>=5
) myNewTable

Hasan Badshah's answer worked for me, but the method is slated to be deprecated and may be problematic for others going forward. Following the MDN web docs on alternative methods, I landed here: PerformanceNavigationTiming.type

if (performance.getEntriesByType("navigation")[0].type === 'back_forward') {
  // back or forward button functionality
}

This doesn't directly solve for back button over the forward button, but was good enough for what I needed. In the docs they detail the available event data that may be helpful with solving your specific needs:

function print_nav_timing_data() {
  // Use getEntriesByType() to just get the "navigation" events
  var perfEntries = performance.getEntriesByType("navigation");

  for (var i=0; i < perfEntries.length; i++) {
    console.log("= Navigation entry[" + i + "]");
    var p = perfEntries[i];
    // dom Properties
    console.log("DOM content loaded = " + (p.domContentLoadedEventEnd - 
    p.domContentLoadedEventStart));
    console.log("DOM complete = " + p.domComplete);
    console.log("DOM interactive = " + p.interactive);

    // document load and unload time
    console.log("document load = " + (p.loadEventEnd - p.loadEventStart));
    console.log("document unload = " + (p.unloadEventEnd - 
    p.unloadEventStart));

    // other properties
    console.log("type = " + p.type);
    console.log("redirectCount = " + p.redirectCount);
  }
}

According to the Docs at the time of this post it is still in a working draft state and is not supported in IE or Safari, but that may change by the time it is finished. Check the Docs for updates.

playing with globals() makes it possible:

import random

alphabet = tuple('abcdefghijklmnopqrstuvwxyz')


print '\n'.join(repr(u) for u in globals() if not u.startswith('__'))

for i in xrange(8):
    globals()[''.join(random.sample(alphabet,random.randint(3,26)))] = random.choice(alphabet)

print

print '\n'.join(repr((u,globals()[u])) for u in globals() if not u.startswith('__'))

one result:

'alphabet'
'random'

('hadmgoixzkcptsbwjfyrelvnqu', 'h')
('nzklv', 'o')
('alphabet', ('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'))
('random', <module 'random' from 'G:\Python27\lib\random.pyc'>)

('isjckyngxvaofdbeqwutl', 'n')
('wmt', 'g')
('aesyhvmw', 'q')

I used random because you don't explain which names of "variables" to give, and which values to create. Because i don't think it's possible to create a name without making it binded to an object.

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

If I'm not using any category then how can I use this code? Actually, I want to use this code for custom post type.

Try this snippet of code

private static boolean isStringInt(String s){
    Scanner in=new Scanner(s);
    return in.hasNextInt();
}

As you can see by reading the other answers, there are a lot of options available. If you are just doing < 10k rows you should go with the second option.

In short, for approx > 10k all the way to say a <100k. It is kind of a gray area. A lot of old geezers will bark at big rollback segments. But honestly hardware and software have made amazing progress to where you may be able to get away with option 2 for a lot of records if you only run the code a few times. Otherwise you should probably commit every 1k-10k or so rows. Here is a snippet that I use. I like it because it is short and I don't have to declare a cursor. Plus it has the benefits of bulk collect and forall.

begin
    for r in (select rownum rn, t.* from foo t) loop
        insert into bar (A,B,C) values (r.A,r.B,r.C);
        if mod(rn,1000)=0 then
            commit;
        end if;
    end;
    commit;
end;

I found this link from the oracle site that illustrates the options in more detail.

Vlookup is good if the reference values (column A, sheet 1) are in ascending order. Another option is Index and Match, which can be used no matter the order (As long as the values in column a, sheet 1 are unique)

This is what you would put in column B on sheet 2

=INDEX(Sheet1!A$1:B$6,MATCH(A1,Sheet1!A$1:A$6),2)

Setting Sheet1!A$1:B$6 and Sheet1!A$1:A$6 as named ranges makes it a little more user friendly.

Instead of using width (which is a suggestion when using flexbox), you could use flex: 0 0 230px; which means:

• 0 = don't grow (shorthand for flex-grow)
• 0 = don't shrink (shorthand for flex-shrink)
• 230px = start at 230px (shorthand for flex-basis)

which means: always be 230px.

See fiddle, thanks @TylerH

Oh, and you don't need the justify-content and align-items here.

img {
    max-width: 100%;
}
#container {
    display: flex;
    x-justify-content: space-around;
    x-align-items: stretch;
    max-width: 1200px;
}
.column.left {
    width: 230px;
    flex: 0 0 230px;
}
.column.right {
    width: 230px;
    flex: 0 0 230px;
    border-left: 1px solid #eee;
}
.column.center {

If other whitespace characters are possible, then you'd want:

testString.split("\\s+");

Set following php parameters to same value in seconds:

session.cookie_lifetime
session.gc_maxlifetime

in php.ini, .htaccess or for example with

ini_set('session.cookie_lifetime', 86400);
ini_set('session.gc_maxlifetime', 86400);

for a day.

This is not a bug in your code. It is coming from .Net's Socket implementation. If you use the overloaded implementation of EndReceive as below you will not get this exception.

    SocketError errorCode;
    int nBytesRec = socket.EndReceive(ar, out errorCode);
    if (errorCode != SocketError.Success)
    {
        nBytesRec = 0;
    }

Adding manifest.file=manifest.mf into project.properties and creating manifest.mf file in the project directory works fine in NB 6.9 and should work also in NB 6.8.

If you're traversing an actual JSON string then you can use a reviver function.

function traverse (json, callback) {
  JSON.parse(json, function (key, value) {
    if (key !== '') {
      callback.call(this, key, value)
    }
    return value
  })
}

traverse('{"a":{"b":{"c":{"d":1}},"e":{"f":2}}}', function (key, value) {
  console.log(arguments)
})

When traversing an object:

function traverse (obj, callback, trail) {
  trail = trail || []

  Object.keys(obj).forEach(function (key) {
    var value = obj[key]

    if (Object.getPrototypeOf(value) === Object.prototype) {
      traverse(value, callback, trail.concat(key))
    } else {
      callback.call(obj, key, value, trail)
    }
  })
}

traverse({a: {b: {c: {d: 1}}, e: {f: 2}}}, function (key, value, trail) {
  console.log(arguments)
})

Technically you could do it with a straight TCP socket. I wouldn't recommend it however. I would highly recommend you use Apache HttpClient instead. In its simplest form:

GetMethod get = new GetMethod("http://httpcomponents.apache.org");
// execute method and handle any error responses.
...
InputStream in = get.getResponseBodyAsStream();
// Process the data from the input stream.
get.releaseConnection();

and here is a more complete example.

You can't use PHP to prevent a timeout issued by nginx.

To configure nginx to allow more time see the proxy_read_timeout directive.

Your condition id !== 0 will always be different that zero because you are assigning a string value. On pages where the element with id views_slideshow_controls_text_next_slideshow-block is not found, you will still try to append the img element, which causes the Cannot read property 'appendChild' of null error.

Instead of assigning a string value, you can assign the DOM element and verify if it exists within the page.

window.onload = function loadContIcons() {
    var elem = document.createElement("img");
    elem.src = "http://arno.agnian.com/sites/all/themes/agnian/images/up.png";
    elem.setAttribute("class", "up_icon");

    var container = document.getElementById("views_slideshow_controls_text_next_slideshow-block");
    if (container !== null) {
        container.appendChild(elem);
    } else console.log("aaaaa");

    var elem1 = document.createElement("img");
    elem1.src = "http://arno.agnian.com/sites/all/themes/agnian/images/down.png";
    elem1.setAttribute("class", "down_icon");

    container = document.getElementById("views_slideshow_controls_text_previous_slideshow-block");
    if (container !== null) {
        container.appendChild(elem1);
    } else console.log("aaaaa");
}

Check out this blog post from Nemikor, which should do what you want.

http://blog.nemikor.com/2009/04/18/loading-a-page-into-a-dialog/

Basically, before calling 'open', you 'load' the content from the other page first.

jQuery('#dialog').load('path to my page').dialog('open'); 

The above answer is useful but in graphs, it is difficult to distinguish between darker gradients of black. One alternative I found is to use gradients of gray colors as follows

palette(gray.colors(10, 0.9, 0.4))
plot(rep(1,10),col=1:10,pch=19,cex=3))

More info on gray scale here.

Added

When I used the code above for different colours like blue and black, the gradients were not that clear. heat.colors() seems more useful.

from datetime import timedelta
try:
    next = (x.replace(day=1) + timedelta(days=31)).replace(day=x.day)
except ValueError:  # January 31 will return last day of February.
    next = (x + timedelta(days=31)).replace(day=1) - timedelta(days=1)

If you simply want the first day of the next month:

next = (x.replace(day=1) + timedelta(days=31)).replace(day=1)

Add this method to a static class:

 public static Rect GetAbsolutePlacement(this FrameworkElement element, bool relativeToScreen = false)
    {
        var absolutePos = element.PointToScreen(new System.Windows.Point(0, 0));
        if (relativeToScreen)
        {
            return new Rect(absolutePos.X, absolutePos.Y, element.ActualWidth, element.ActualHeight);
        }
        var posMW = Application.Current.MainWindow.PointToScreen(new System.Windows.Point(0, 0));
        absolutePos = new System.Windows.Point(absolutePos.X - posMW.X, absolutePos.Y - posMW.Y);
        return new Rect(absolutePos.X, absolutePos.Y, element.ActualWidth, element.ActualHeight);
    }

Set relativeToScreen paramater to true for placement from top left corner of whole screen or to false for placement from top left corner of application window.

If you deleted multiple files locally and did not commit the changes, go to your local repository path, open the git shell and type.

$ git checkout HEAD .

All the deleted files before the last commit will be recovered.

Adding "." will recover all the deleted the files in the current repository, to their respective paths.

For more details checkout the documentation.

It's as easy as using select:

Get-Content file.txt | Select -Index (line - 1)

E.g. to get line 5

Get-Content file.txt | Select -Index 4

Or you can use:

(Get-Content file.txt)[4]

If you have Python installed, you can do

python -c "import datetime;print(datetime.date.today().strftime('%Y-%m-%d'))"

You can easily adapt the format string to your needs.

The user "geoand" is right in pointing out the reasons here and giving a solution. But a better approach is to encapsulate your configuration into a separate class, say SystemContiguration java class and then inject this class into what ever services you want to use those fields.

Your current way(@grahamrb) of reading config values directly into services is error prone and would cause refactoring headaches if config setting name is changed.

If you know the count of your columns (f.e. it's equal to a collection list). You can simply use this one liner to adjust all columns of one sheet (if you use at least java 8):

IntStream.range(0, columnCount).forEach((columnIndex) -> sheet.autoSizeColumn(columnIndex));

Type the following command to import sql data file:

$ mysql -u username -p -h localhost DATA-BASE-NAME < data.sql

In this example, import 'data.sql' file into 'blog' database using vivek as username:

$ mysql -u vivek -p -h localhost blog < data.sql

If you have a dedicated database server, replace localhost hostname with with actual server name or IP address as follows:

$ mysql -u username -p -h 202.54.1.10 databasename < data.sql

To export a database, use the following:

mysqldump -u username -p databasename > filename.sql

Note the < and > symbols in each case.

For windows, unix, or Mac? On the Mac or *nix you can use command line or GUI versions of emacs or vim.

For the Mac: TextWrangler to handle big files well. I'm not versed enough on the Windows landscape to help out there.

Pass the id that you want to remove from the array to the given function 

from the controller( Function can be in the same controller but prefer to keep it in a service)

    function removeInfo(id) {
    let item = bdays.filter(function(item) {
      return bdays.id=== id;
    })[0];
    let index = bdays.indexOf(item);
    data.device.splice(indexOfTabDetails, 1);
  }

I suspect that this occurs after an attempt to undeploy your app. Do you ever kill off that thread that you've initialised during the init() process ? I would do this in the corresponding destroy() method.

i found an easy solution, export the database, edit it what you want to edit in a text editor, then import it. Done

You need to be aware that month is zero based so when you do the getMonth you will need to add 1. In the example below we have to add 1 to Januaray as 1 and not 0

    Calendar c = Calendar.getInstance();
    c.set(2011, 2, 1);
    c.add(Calendar.MONTH, -1);
    int month = c.get(Calendar.MONTH) + 1;
    assertEquals(1, month);

Add following codesnippet in your cofig file

In addition of github/hub, which acts as a proxy to Git, you now (February 2020) have cli/cli:

See "Supercharge your command line experience: GitHub CLI is now in beta"

Create a pull request

Create a branch, make several commits to fix the bug described in the issue, and use gh to create a pull request to share your contribution.

By using GitHub CLI to create pull requests, it also automatically creates a fork when you don’t already have one, and it pushes your branch and creates your pull request to get your change merged.

And in April 2020: "GitHub CLI now supports autofilling pull requests and custom configuration"

GitHub CLI 0.7 is out with several of the most highly requested enhancements from the feedback our beta users have provided.
Since the last minor release, 0.6, there are three main features:

• Configure gh to use your preferred editor with gh config set editor [editor].
• Configure gh to default to SSH with gh config set git_protocol ssh.
  The default Git protocol is HTTPS.
• Autofill the title and body of a pull request from your commits with gh pr create --fill.

So:

gh pr create --fill

Do not include bin in your JAVA_HOME env variable

You can do this in jEdit, by using the "Return value of a BeanShell snippet" option in jEdit's find and replace dialog. Just search for " [a-z]" and replace it by " _0.toUpperCase()" (without quotes)

In my case, this happen because of I deleted the Main.storyboard and in general tab Main Interface property cleared and added custom one as Start. After I Change the Main Interface to Start.storyboard except Start it's working.

remove the range.

for i in myList

range takes in an integer. you want for each element in the list.

Most of the answers here are more or less related to application programming. Here is an example from embedded systems programming. For example below is an excerpt from the reference manual of NXP's Kinetis KL13 series microcontroller, this code snippet is used to run bootloader, which resides in ROM, from firmware:

" To get the address of the entry point, the user application reads the word containing the pointer to the bootloader API tree at offset 0x1C of the bootloader's vector table. The vector table is placed at the base of the bootloader's address range, which for the ROM is 0x1C00_0000. Thus, the API tree pointer is at address 0x1C00_001C.

The bootloader API tree is a structure that contains pointers to other structures, which have the function and data addresses for the bootloader. The bootloader entry point is always the first word of the API tree. "

uint32_t runBootloaderAddress;
void (*runBootloader)(void * arg);
// Read the function address from the ROM API tree.
runBootloaderAddress = **(uint32_t **)(0x1c00001c);
runBootloader = (void (*)(void * arg))runBootloaderAddress;
// Start the bootloader.
runBootloader(NULL);

bool exists = arr.Contains("One");

If using Vagrant try reloading your box. This solved my issue.

http://developer.android.com/reference/android/location/Location.html

Look into distanceTo or distanceBetween. You can create a Location object from a latitude and longitude:

Location location = new Location("");
location.setLatitude(lat);
location.setLongitude(lon);

setTimeout(expression, timeout); runs the code/function once after the timeout.

setInterval(expression, timeout); runs the code/function in intervals, with the length of the timeout between them.

Example:

var intervalID = setInterval(alert, 1000); // Will alert every second.
// clearInterval(intervalID); // Will clear the timer.

setTimeout(alert, 1000); // Will alert once, after a second.

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:

Since I can't comment on answer, beware to use following solution:

$db = new PDO($dsn, $user, $password);

$sql = file_get_contents('file.sql');

$qr = $db->exec($sql);

There is a bug in PHP PDO https://bugs.php.net/bug.php?id=61613

db->exec('SELECT 1; invalidstatement; SELECT 2');

won't error out or return false (tested on PHP 5.5.14).

If you really need to check then it's better to use abstract base classes rather than concrete classes. For an integer that would mean:

>>> import numbers
>>> isinstance(3, numbers.Integral)
True

This doesn't restrict the check to just int, or just int and long, but also allows other user-defined types that behave as integers to work.

Here is the code to read the excel data by column.

If it were about committed changes, you should have a look at git-rebase, but as pointed out in comment by VonC, as you're talking about local changes, git-stash would certainly be the good way to do this.

Building on @Tim's example to make a self-contained method:

import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.util.ArrayList;

public class Shell {

    /** Returns null if it failed for some reason.
     */
    public static ArrayList<String> command(final String cmdline,
    final String directory) {
        try {
            Process process = 
                new ProcessBuilder(new String[] {"bash", "-c", cmdline})
                    .redirectErrorStream(true)
                    .directory(new File(directory))
                    .start();

            ArrayList<String> output = new ArrayList<String>();
            BufferedReader br = new BufferedReader(
                new InputStreamReader(process.getInputStream()));
            String line = null;
            while ( (line = br.readLine()) != null )
                output.add(line);

            //There should really be a timeout here.
            if (0 != process.waitFor())
                return null;

            return output;

        } catch (Exception e) {
            //Warning: doing this is no good in high quality applications.
            //Instead, present appropriate error messages to the user.
            //But it's perfectly fine for prototyping.

            return null;
        }
    }

    public static void main(String[] args) {
        test("which bash");

        test("find . -type f -printf '%T@\\\\t%p\\\\n' "
            + "| sort -n | cut -f 2- | "
            + "sed -e 's/ /\\\\\\\\ /g' | xargs ls -halt");

    }

    static void test(String cmdline) {
        ArrayList<String> output = command(cmdline, ".");
        if (null == output)
            System.out.println("\n\n\t\tCOMMAND FAILED: " + cmdline);
        else
            for (String line : output)
                System.out.println(line);

    }
}

(The test example is a command that lists all files in a directory and its subdirectories, recursively, in chronological order.)

By the way, if somebody can tell me why I need four and eight backslashes there, instead of two and four, I can learn something. There is one more level of unescaping happening than what I am counting.

Edit: Just tried this same code on Linux, and there it turns out that I need half as many backslashes in the test command! (That is: the expected number of two and four.) Now it's no longer just weird, it's a portability problem.

If you are locked out and WiFi is turned off in your Androud device then one solution is to connect your phone to a PC (connected to internet) and try to login with your google account. - it worked for me.

Sounds like you probably want a simple method like this:

public String getValueOrDefault(String value, String defaultValue) {
    return isNotNullOrEmpty(value) ? value : defaultValue;
}

Then:

String result = getValueOrDefault(System.getProperty("XYZ"), "default");

At this point, you don't need temp... you've effectively used the method parameter as a way of initializing the temporary variable.

If you really want temp and you don't want an extra method, you can do it in one statement, but I really wouldn't:

public class Test {
    public static void main(String[] args) {
        String temp, result = isNotNullOrEmpty(temp = System.getProperty("XYZ")) ? temp : "default";
        System.out.println("result: " + result);
        System.out.println("temp: " + temp);
    }

    private static boolean isNotNullOrEmpty(String str) {
        return str != null && !str.isEmpty();
    }
}

Here's a decent explanation of clone() if you end up needing it...

Here: clone (Java method)

Use tabs, they work when inputting file paths in vim escape mode!

if you want your datetime.now() precise till the minute , you can use

datetime.strptime(datetime.now().strftime('%Y-%m-%d %H:%M'), '%Y-%m-%d %H:%M')

similarly for hour it will be

datetime.strptime(datetime.now().strftime('%Y-%m-%d %H'), '%Y-%m-%d %H')

It is kind of a hack, if someone has a better solution, I am all ears

Sounds like you might want a light box,and since you didnt tag your question with jQuery included is a pure JS example of how to make one.

JS

var opener = document.getElementById("opener");

opener.onclick = function(){

    var lightbox = document.getElementById("lightbox"),
        dimmer = document.createElement("div");

    dimmer.style.width =  window.innerWidth + 'px';
    dimmer.style.height = window.innerHeight + 'px';
    dimmer.className = 'dimmer';

    dimmer.onclick = function(){
        document.body.removeChild(this);   
        lightbox.style.visibility = 'hidden';
    }

    document.body.appendChild(dimmer);

    lightbox.style.visibility = 'visible';
    lightbox.style.top = window.innerHeight/2 - 50 + 'px';
    lightbox.style.left = window.innerWidth/2 - 100 + 'px';
    return false;
}

Markup

<div id="lightbox">Testing out the lightbox</div>
<a href="#" id="opener">Click me</a>

CSS

#lightbox{
    visibility:hidden;
    position:absolute;
    background:red;
    border:2px solid #3c3c3c;
    color:white;
    z-index:100;
    width: 200px;
    height:100px;
    padding:20px;
}

.dimmer{
    background: #000;
    position: absolute;
    opacity: .5;
    top: 0;
    z-index:99;
}

In my case above mentioned methods work fine with php but when i try to upload files with these methods in node.js then i have some problem. So instead of using $http({..,..,...}) use the normal jquery ajax.

For select file use this

<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this)"/>

And in controller

$scope.uploadFile = function(element) {   
var data = new FormData();
data.append('file', $(element)[0].files[0]);
jQuery.ajax({
      url: 'brand/upload',
      type:'post',
      data: data,
      contentType: false,
      processData: false,
      success: function(response) {
      console.log(response);
      },
      error: function(jqXHR, textStatus, errorMessage) {
      alert('Error uploading: ' + errorMessage);
      }
 });   
};

If you are allowing anonymous users as well as those logged in with email you can use firebase.auth().currentUser.isAnonymous, which will return either true or false.

@Before(JUnit4) -> @BeforeEach(JUnit5) - method is called before every test

@After(JUnit4) -> @AfterEach(JUnit5) - method is called after every test

@BeforeClass(JUnit4) -> @BeforeAll(JUnit5) - static method is called before executing all tests in this class. It can be a large task as starting server, read file, making db connection...

@AfterClass(JUnit4) -> @AfterAll(JUnit5) - static method is called after executing all tests in this class.

J(2)EE, strictly speaking, is a set of APIs (as the current top answer has it) which enable a programmer to build distributed, transactional systems. The idea was to abstract away the complicated distributed, transactional bits (which would be implemented by a Container such as WebSphere or Weblogic), leaving the programmer to develop business logic free from worries about storage mechanisms and synchronization.

In reality, it was a cobbled-together, design-by-committee mish-mash, which was pushed pretty much for the benefit of vendors like IBM, Oracle and BEA so they could sell ridicously over-complicated, over-engineered, over-useless products. Which didn't have the most basic features (such as scheduling)!

J2EE was a marketing construct.

Another option is to use diffutil . It will compare the original list against the new list and use the new list as the update if there is a change.

Basically, we can use DiffUtil to compare the old data vs new data and let it call notifyItemRangeRemoved, and notifyItemRangeChanged and notifyItemRangeInserted on your behalf.

A quick example of using diffUtil instead of notifyDataSetChanged:

DiffResult diffResult = DiffUtil
                .calculateDiff(new MyDiffUtilCB(getItems(), items));

//any clear up on memory here and then
diffResult.dispatchUpdatesTo(this);

//and then, if necessary
items.clear()
items.addAll(newItems)

I do the calculateDiff work off the main thread in case it's a big list.

I wrote a program with wpf and used Database for showing images and this is my code:

SqlConnection con = new SqlConnection(@"Data Source=HITMAN-PC\MYSQL;
                                      Initial Catalog=Payam;
                                      Integrated Security=True");

SqlDataAdapter da = new SqlDataAdapter("select * from news", con);

DataTable dt = new DataTable();
da.Fill(dt);

string adress = dt.Rows[i]["ImgLink"].ToString();
ImageSource imgsr = new BitmapImage(new Uri(adress));
PnlImg.Source = imgsr;

Try SELECT CAST(field1 AS DECIMAL(10,2)) field1 and replace 10,2 with whatever precision you need.

You can simply use the jQuery Validate plugin as follows.

jQuery:

$(document).ready(function () {

    $('#myform').validate({ // initialize the plugin
        rules: {
            field1: {
                required: true,
                email: true
            },
            field2: {
                required: true,
                minlength: 5
            }
        }
    });

});

HTML:

<form id="myform">
    <input type="text" name="field1" />
    <input type="text" name="field2" />
    <input type="submit" />
</form>

    // Check connection
    if (mysqli_connect_errno())
      {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }

    $result = mysqli_query($con,"SELECT * FROM employee");

    while($row = mysqli_fetch_array($result))

You can similarly echo it inside your table

<?php
 echo "<table>";
 while($row = mysqli_fetch_array($result))
          {
          echo "<tr><td>" . $row['FirstName'] . "</td><td> " . $row['LastName'] . "</td></tr>"; //these are the fields that you have stored in your database table employee
          }
 echo "</table>";
 mysqli_close($con);
?>

In the Android Studio go to File then Close Project. Then take the folder (in the workspace folder) of the project and copy it to a flash memory or whatever. Then when you get comfortable at home, copy this folder in the workspace folder you've already created, open the Android Studio and go to File then Open and import this project into your workspace.

The problem you have with this is that you're searching for the wrong term here, because in Android, exporting a project means compiling it to .apk file (not exporting the project). Import/Export is used for the .apk management, what you need is Open/Close project, the other thing is just copy/paste.

This is the code with two bug fixes. The first bug fix was mentioned by Royi Namir in the comment on the accepted answer to this question. The bug is described on StackOverflow at Bug in Trigger Code. The second one was found by @Fandango68 and fixes columns with multiples words for their names.

You can use:

ls -lh

Using this command you'll see the apparent space of the directory and true space of the files and in details the names of the files displayed, besides the size and creation date of each.

It would be too tedious to alter function usages in all html pages to return false.

So here is a tested solution that patches only the function itself:

function callmymethod(myVal) {
    // doing custom things with myVal

    // cancel default event action
    var event = window.event || callmymethod.caller.arguments[0];
    event.preventDefault ? event.preventDefault() : (event.returnValue = false);

    return false;
}    

This correctly prevents IE6, IE11 and latest Chrome from visiting href="#" after onclick event handler completes.

(I presume you are aware that using UDP(User Datagram Protocol) does not guarantee delivery, checks for duplicates and congestion control and will just answer your question).

In your server this line:

var data = udpServer.Receive(ref groupEP);

re-assigns groupEP from what you had to a the address you receive something on.

This line:

udpServer.Send(new byte[] { 1 }, 1); 

Will not work since you have not specified who to send the data to. (It works on your client because you called connect which means send will always be sent to the end point you connected to, of course we don't want that on the server as we could have many clients). I would:

UdpClient udpServer = new UdpClient(UDP_LISTEN_PORT);

while (true)
{
    var remoteEP = new IPEndPoint(IPAddress.Any, 11000);
    var data = udpServer.Receive(ref remoteEP);
    udpServer.Send(new byte[] { 1 }, 1, remoteEP); // if data is received reply letting the client know that we got his data          
}

Also if you have server and client on the same machine you should have them on different ports.

I don't think this point has been added and since I just spent some time hunting this down I hope it can help.

I am working with IIS 7 and using the ASP.NET v4 Framework.
In my case it was important that an entry be added to both the and section of the entry in the web.config file.

My web.config file has a lot of handlers and in my case it was easiest to add the ScriptResources entry to the top of the handlers section. Most importantly, it needs to be placed before any entry that will act as a wildcard and capture the request. Adding it after a wildcard entry will cause it to be ignored and the error will still appear.

The module can be added to the top or bottom of the section.

Web.config Sample:

<system.webServer>
    <handlers>
      <clear />
      <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
      <!-- Make sure wildcard rules are below the ScriptResource tag -->
    </handlers>
    <modules>
      <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <!-- Other modules are added here -->
    </modules>
  </system.webServer>

BrenBarn is correct. The error means you tried to do something like None[5]. In the backtrace, it says self.imageDef=self.values[2], which means that your self.values is None.

You should go through all the functions that update self.values and make sure you account for all the corner cases.

Here is a version that uses a sequence or numbers table rather than a loop. You can modify the WHERE clause to suite your personal rules for when to convert a character to upper case. I have just included a simple set that will upper case any letter that is proceeded by a non-letter with the exception of apostrophes. This does how ever mean that 123apple would have a match on the "a" because "3" is not a letter. If you want just white-space (space, tab, carriage-return, line-feed), you can replace the pattern '[^a-z]' with '[' + Char(32) + Char(9) + Char(13) + Char(10) + ']'.

CREATE FUNCTION String.InitCap( @string nvarchar(4000) ) RETURNS nvarchar(4000) AS
BEGIN

-- 1. Convert all letters to lower case
    DECLARE @InitCap nvarchar(4000); SET @InitCap = Lower(@string);

-- 2. Using a Sequence, replace the letters that should be upper case with their upper case version
    SELECT @InitCap = Stuff( @InitCap, n, 1, Upper( SubString( @InitCap, n, 1 ) ) )

Use time

Let's say you have the initial dates as strings like these:
date1 = "31/12/2015"
date2 = "01/01/2016"

You can do the following:
newdate1 = time.strptime(date1, "%d/%m/%Y") and newdate2 = time.strptime(date2, "%d/%m/%Y") to convert them to python's date format. Then, the comparison is obvious:

newdate1 > newdate2 will return False
newdate1 < newdate2 will return True

I have found a bug in solgraph that it is utilizing older version of solidity-parser that does not seem to be intelligent enough to capture new enhancement done for solidity programming language itself e.g. emit keyword for Event

After two dozens of comments to understand the situation, it was found that the libhdf5.so.7 was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.

For future reference: other than checking LD_LIBRARY_PATH, it's always a good idea to check a library with nm -D to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum revealed that the files were actually different.

size_t is the size of a pointer.

So in 32 bits or the common ILP32 (integer, long, pointer) model size_t is 32 bits. and in 64 bits or the common LP64 (long, pointer) model size_t is 64 bits (integers are still 32 bits).

There are other models but these are the ones that g++ use (at least by default)

If you have a <script> tag anywhere on your page (even in the HTML, even if it is an empty tag with a src), then a transition must be activated by some event (it won't fire automatically when the page loads).

If you are using TextEditingController then set the text to it, like below

TextEditingController _controller = new TextEditingController();


_controller.text = 'your initial text';

final your_text_name = TextFormField(
      autofocus: false,
      controller: _controller,
      decoration: InputDecoration(
        hintText: 'Hint Value',
      ),
    );

and if you are not using any TextEditingController then you can directly use initialValue like below

final last_name = TextFormField(
      autofocus: false,
      initialValue: 'your initial text',
      decoration: InputDecoration(
        hintText: 'Last Name',
      ),
    );

I faced the same issue. String.Replace('\\.','') is not valid statement and throws the same error. Thanks to C# we can use double quotes instead of single quotes and following works String.Replace("\\.","")

You cannot directly see the query result using mysql_query its only fires the query in mysql nothing else.

For getting the result you have to add a lil things in your script like

require_once('db.php');  
 $sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )  FROM  modul1open) ORDER BY idM1O LIMIT 1";

 $result = mysql_query($sql);
 //echo [$result];
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
    print_r($row);
}

This will give you result;

Do a git status to find out if your file is actually in your index or the commit.

It is easy as a beginner to misunderstand the index/staging area.

I view it as a 'progress pinboard'. I therefore have to add the file to the pinboard before I can commit it (i.e. a copy of the complete pinboard), I have to update the pinboard when required, and I also have to deliberately remove files from it when I've finished with them - simply creating, editing or deleting a file doesn't affect the pinboard. It's like 'storyboarding'.

Edit: As others noted, You should do the edits locally and then push the updated repo, rather than attempt to edit directly on github.

There are a number of tools available which help debugging segmentation faults and I would like to add my favorite tool to the list: Address Sanitizers (often abbreviated ASAN).

Modern¹ compilers come with the handy -fsanitize=address flag, adding some compile time and run time overhead which does more error checking.

According to the documentation these checks include catching segmentation faults by default. The advantage here is that you get a stack trace similar to gdb's output, but without running the program inside a debugger. An example:

int main() {
  volatile int *ptr = (int*)0;
  *ptr = 0;
}

$ gcc -g -fsanitize=address main.c
$ ./a.out
AddressSanitizer:DEADLYSIGNAL

The output is slightly more complicated than what gdb would output but there are upsides:

• There is no need to reproduce the problem to receive a stack trace. Simply enabling the flag during development is enough.

• ASANs catch a lot more than just segmentation faults. Many out of bounds accesses will be caught even if that memory area was accessible to the process.

¹ That is Clang 3.1+ and GCC 4.8+.
