CKEDITOR.config.enterMode = CKEDITOR.ENTER_BR; - this works perfectly for me. Have you tried clearing your browser cache - this is an issue sometimes.
You can also check it out with the jQuery adapter:

<script type="text/javascript" src="/js/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="/js/ckeditor/adapters/jquery.js"></script>
<script type="text/javascript">
$(function() {
    $('#your_textarea').ckeditor({
        toolbar: 'Full',
        enterMode : CKEDITOR.ENTER_BR,
        shiftEnterMode: CKEDITOR.ENTER_P
    });
});
</script>

UPDATE according to @Tomkay's comment:

Since version 3.6 of CKEditor you can configure if you want inline content to be automatically wrapped with tags like <p></p>. This is the correct setting:

CKEDITOR.config.autoParagraph = false;

Source: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.autoParagraph

Another option is to use the Decimal.Round Method

You can also do it this way

private static string GetPaddingSequence(int padding)
{
      StringBuilder SB = new StringBuilder();
      for (int i = 0; i < padding; i++)
      {
           SB.Append("0");
      }

      return SB.ToString();
  }

public static string FormatNumber(int number, int padding)
{
    return number.ToString(GetPaddingSequence(padding));
}

Finally call the function FormatNumber

string x = FormatNumber(1,2);

Output will be 01 which is based on your padding parameter. Increasing it will increase the number of 0s

public static long randomLong(long min, long max)
{
    try
    {
        Random  random  = new Random();
        long    result  = min + (long) (random.nextDouble() * (max - min));
        return  result;
    }
    catch (Throwable t) {t.printStackTrace();}
    return 0L;
}

With jQuery:

$.post("test.php", { json_string:JSON.stringify({name:"John", time:"2pm"}) });

Without jQuery:

var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
xmlhttp.open("POST", "/json-handler");
xmlhttp.setRequestHeader("Content-Type", "application/json");
xmlhttp.send(JSON.stringify({name:"John Rambo", time:"2pm"}));

I can't assign a null to a String?

No. std::string is not a pointer type; it cannot be made "null." It cannot represent the absence of a value, which is what a null pointer is used to represent.

It can be made empty, by assigning an empty string to it (s = "" or s = std::string()) or by clearing it (s.clear()).

I found very nice solution, that SOLVED my problem. The trick is to edit the svn DB (wc.db).

The solution is described on this page : http://www.exchangeconcept.com/2015/01/svn-e155037-previous-operation-has-not-finished-run-cleanup-if-it-was-interrupted/

If link is down, just look and follow this instructions:

I used sqlite tool from http://sqlitebrowser.org/.

.Click() - Perform only click operation as like mouse click.

.Submit() - Perform Enter operation as like keyboard Enter event.

For Example. Consider a login page where it contains username and password and submit button.

On filling password if we want to login without clicking login button. we need to user .submit button on password where .click() operation does not work.[to login into application]

Brif.

driver.get("https:// anyURL"); 
driver.manage().window().maximize(); 
driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS); 
driver.findElement(By.id("txtUserId")).sendKeys("[email protected]"); 
WebElement text = driver.findElement(By.id("txtPassword")); text.sendKeys("password"); 
Thread.sleep(1000); 
text.click();   //This will not work - it will on perform click operation not submit operation
text.submit(); //This will perform submit operation has enter key 

To make use of the Room without abuse of the @Query annotation first use @Query to select all rows and put them in a list, for example:

@Query("SELECT * FROM your_class_table")

List`<`your_class`>` load_all_your_class();

Put his list into the delete annotation, for example:

@Delete

void deleteAllOfYourTable(List`<`your_class`>` your_class_list);

Let me propose an improved method when the values of the dictionnary are lists with the same lenght :

import numpy

def dctToNdarray (dd, szFormat = 'f8'):
    '''
    Convert a 'rectangular' dictionnary to numpy NdArray
    entry 
        dd : dictionnary (same len of list 
    retrun
        data : numpy NdArray 
    '''
    names = dd.keys()
    firstKey = dd.keys()[0]
    formats = [szFormat]*len(names)
    dtype = dict(names = names, formats=formats)
    values = [tuple(dd[k][0] for k in dd.keys())]
    data = numpy.array(values, dtype=dtype)
    for i in range(1,len(dd[firstKey])) :
        values = [tuple(dd[k][i] for k in dd.keys())]
        data_tmp = numpy.array(values, dtype=dtype)
        data = numpy.concatenate((data,data_tmp))
    return data

dd = {'a':[1,2.05,25.48],'b':[2,1.07,9],'c':[3,3.01,6.14]}
data = dctToNdarray(dd)
print data.dtype.names
print data

I think it's asking you to do this:

SELECT ID
FROM (SELECT ID,
             msisdn 
      FROM (SELECT * FROM TT2) as myalias
     ) as anotheralias;

But why would you write this query in the first place?

my experience

1. get your php version

   php --version

2. Instal package for your php version

   sudo apt-get install php7.4-xml

3. Restart apache

   sudo systemctl reload apache2

Use this code it works perfectly for odd or even list sizes. Hope it help somebody .

 int listSize = listOfArtist.size();
 int mid = 0;
 if (listSize % 2 == 0) {
    mid = listSize / 2;
    Log.e("Parting", "You entered an even number. mid " + mid
                    + " size is " + listSize);
 } else {
    mid = (listSize + 1) / 2;
    Log.e("Parting", "You entered an odd number. mid " + mid
                    + " size is " + listSize);
 }
 //sublist returns List convert it into arraylist * very important
 leftArray = new ArrayList<ArtistModel>(listOfArtist.subList(0, mid));
 rightArray = new ArrayList<ArtistModel>(listOfArtist.subList(mid,
                listSize));

I've written a small Class to capitalize all the words in a String.

Optional multiple delimiters, each one with its behavior (capitalize before, after, or both, to handle cases like O'Brian);

Optional Locale;

Don't breaks with Surrogate Pairs.

To play a notification sound using python, call a music player, such as vlc. VLC prompted me to use its commandline version, cvlc, instead.

from subprocess import call
call(["cvlc", "--play-and-exit", "myNotificationTone.mp3"])

It requires vlc to be preinstalled on the device. Tested on Linux(Ubuntu 16.04 LTS); Running Python 3.5.

you can use String format to include variables within strings

i use this code to include 2 variable in string:

String myString = String.format("this is my string %s %2d", variable1Name, variable2Name);

As Bakkal explained, for the keyboard shortcuts, in netbeans you can go to tools->options->editor->code templates and add or edit your own shortcuts.

In Eclipse it's on templates.

If the problem is 100% here

EffectSelectorForm effectSelectorForm = new EffectSelectorForm(Effects);

There's only one possible explanation: property/variable "Effects" is not initialized properly... Debug your code to see what you pass to your objects.

EDIT after several hours

There were some problems:

• MEF attribute [Import] didn't work as expected, so we replaced it for the time being with a manually populated List<>. While the collection was null, it was causing exceptions later in the code, when the method tried to get the type of the selected item and there was none.

• several event handlers weren't wired up to control events

Some problems are still present, but I believe OP's original problem has been fixed. Other problems are not related to this one.

One more reason for this error (assuming that gradle properly setup) is incompatibility between andorid.gradle tools and gradle itself - check out this answer for the complete compatibility table.

In my case the error was the same as in the question and the stacktrace as following:

java.lang.NullPointerException
    at java.util.Objects.requireNonNull(Objects.java:203)
    at com.android.build.gradle.BasePlugin.lambda$configureProject$1(BasePlugin.java:436)

    at org.gradle.internal.dispatch.ReflectionDispatch.dispatch(ReflectionDispatch.java:24)
    at org.gradle.internal.event.AbstractBroadcastDispatch.dispatch(AbstractBroadcastDispatch.java:42)
    ...

I've fixed that by upgrading com.android.tools.build:gradle to the current latest 3.1.4

buildscript {
    repositories {
        ...
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
    }
}

Gradle version is 4.6

You can use reduce instead of loops to appear clever, but at the risk of having your fellow developers think of you as a smart-ass.

function isArrayContentSame(a, b) {
  if (Array.isArray(a) && Array.isArray(b) && a.length == b.length) {
    a = a.concat().sort()
    b = b.concat().sort()
    return a.reduce((acc,e,i) => acc && e === b[i], true)
  } else {
    return false;
  }
}

IOW, extern is redundant, and does nothing.

That is why, 10 years later:

• A code transformation tool like Coccinelle will tend to flag extern in function declaration for removal;
• a codebase like git/git follows that conclusion and removes extern from its code (for Git 2.22, Q2 2019).

*.[ch]: remove extern from function declarations using spatch

There has been a push to remove extern from function declarations.

Remove some instances of "extern" for function declarations which are caught by Coccinelle.
Note that Coccinelle has some difficulty with processing functions with __attribute__ or varargs so some extern declarations are left behind to be dealt with in a future patch.

This was the Coccinelle patch used:

  @@
    type T;
    identifier f;
    @@
    - extern
    T f(...);

and it was run with:

  $ git ls-files \*.{c,h} |
    grep -v ^compat/ |
    xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place

This is not always straightforward though:

compat/*.[ch]: remove extern from function declarations using spatch

In 5545442 (*.[ch]: remove extern from function declarations using spatch, 2019-04-29, Git v2.22.0-rc0), we removed externs from function declarations using spatch but we intentionally excluded files under compat/ since some are directly copied from an upstream and we should avoid churning them so that manually merging future updates will be simpler.

In the last commit, we determined the files which taken from an upstream so we can exclude them and run spatch on the remainder.

This was the Coccinelle patch used:

@@
type T;
identifier f;
@@
- extern
  T f(...);

and it was run with:

$ git ls-files compat/\*\*.{c,h} |
    xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place
$ git checkout -- \
    compat/regex/ \
    compat/inet_ntop.c \
    compat/inet_pton.c \
    compat/nedmalloc/ \
    compat/obstack.{c,h} \
    compat/poll/

Coccinelle has some trouble dealing with __attribute__ and varargs so we ran the following to ensure that no remaining changes were left behind:

$ git ls-files compat/\*\*.{c,h} |
    xargs sed -i'' -e 's/^\(\s*\)extern \([^(]*([^*]\)/\1\2/'
$ git checkout -- \
    compat/regex/ \
    compat/inet_ntop.c \
    compat/inet_pton.c \
    compat/nedmalloc/ \
    compat/obstack.{c,h} \
    compat/poll/

Note that with Git 2.24 (Q4 2019), any spurious extern is dropped.

promisor-remote.h: drop extern from function declaration

During the creation of this file, each time a new function declaration was introduced, it included an extern.
However, starting from 5545442 (*.[ch]: remove extern from function declarations using spatch, 2019-04-29, Git v2.22.0-rc0), we've been actively trying to prevent externs from being used in function declarations because they're unnecessary.

Remove these spurious externs.

The file should be located in the WEB-INF/classes directory. This directory structure should be packaged within the war file.

As Joshua M pointed out, the zoom function isn't supported only in Firefox, but you can simply fix this as shown:

div.zoom {
  zoom: 2; /* all browsers */
 -moz-transform: scale(2);  /* Firefox */
}

To binary:

bin(byte)[2:].zfill(8)

I also wanted to load any iframe inside modal window. What I did was, Created an iframe inside Modal and passing the source of target iframe to the iframe inside the modal.

  var modalWindow = document.getElementById('iframeModalWindow');_x000D_
  modalWindow.src = "";_x000D_

This may also occur if you are trying to invoke an xml file instead of the exe application.

If it's a list of constants then you can use Select Case as follows:

Dim Item$: Item = "A"

Select Case Item
  Case "A", "B", "C"
    ' If 'Item' is in the list then do something.
  Case Else
    ' Otherwise do something else.
End Select

Refering to MySql documentation,

CREATE DATABASE creates a database with the given name. To use this statement, you need the CREATE privilege for the database. CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.

This worked for me. It looks like a button and behaves like a link. You can bookmark it for example.

<a href="mypage.aspx?param1=1" style="text-decoration:none;">
    <asp:Button PostBackUrl="mypage.aspx?param1=1" Text="my button-like link" runat="server" />
</a>

As a complementary, to produce patch for only one specific commit, use:

git format-patch -1 <sha>

When the patch file is generated, make sure your other repo knows where it is when you use git am ${patch-name}

Before adding the patch, use git apply --check ${patch-name} to make sure that there is no confict.

Executing seq(1, 10, 1) does what 1:10 does. You can change the last parameter of seq, i.e. by, to be the step of whatever size you like.

> #a vector of even numbers
> seq(0, 10, by=2) # Explicitly specifying "by" only to increase readability 
> [1]  0  2  4  6  8 10

They are slightly different - the ETag does not have any information that the client can use to determine whether or not to make a request for that file again in the future. If ETag is all it has, it will always have to make a request. However, when the server reads the ETag from the client request, the server can then determine whether to send the file (HTTP 200) or tell the client to just use their local copy (HTTP 304). An ETag is basically just a checksum for a file that semantically changes when the content of the file changes.

The Expires header is used by the client (and proxies/caches) to determine whether or not it even needs to make a request to the server at all. The closer you are to the Expires date, the more likely it is the client (or proxy) will make an HTTP request for that file from the server.

So really what you want to do is use BOTH headers - set the Expires header to a reasonable value based on how often the content changes. Then configure ETags to be sent so that when clients DO send a request to the server, it can more easily determine whether or not to send the file back.

One last note about ETag - if you are using a load-balanced server setup with multiple machines running Apache you will probably want to turn off ETag generation. This is because inodes are used as part of the ETag hash algorithm which will be different between the servers. You can configure Apache to not use inodes as part of the calculation but then you'd want to make sure the timestamps on the files are exactly the same, to ensure the same ETag gets generated for all servers.

Indeed, there is no defined standard. To support that information, have a look at wikipedia, in the Query String chapter. There is the following comment:

While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field.[3][4]

Furthermore, when you take a look at the RFC 3986, in section 3.4 Query, there is no definition for parameters with multiple values.

Most applications use the first option you have shown: http://server/action?id=a&id=b. To support that information, take a look at this Stackoverflow link, and this MSDN link regarding ASP.NET applications, which use the same standard for parameters with multiple values.

However, since you are developing the APIs, I suggest you to do what is the easiest for you, since the caller of the API will not have much trouble creating the query string.

After discussion posting updated answer:

Option Explicit
Sub test()

    Dim wk As String, yr As String
    Dim fname As String, fpath As String
    Dim owb As Workbook

    With Application
        .DisplayAlerts = False
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    wk = ComboBox1.Value
    yr = ComboBox2.Value
    fname = yr & "W" & wk
    fpath = "C:\Documents and Settings\jammil\Desktop\AutoFinance\ProjectControl\Data"

    On Error GoTo ErrorHandler
    Set owb = Application.Workbooks.Open(fpath & "\" & fname)

    'Do Some Stuff

    With owb
        .SaveAs fpath & Format(Date, "yyyymm") & "DB" & ".xlsx", 51

Else: Call Clear

End Sub

Error Handling:

You could try something like this to catch a specific error:

    On Error Resume Next
    Set owb = Application.Workbooks.Open(fpath & "\" & fname)
    If Err.Number = 1004 Then
    GoTo FileNotFound
    Else
    End If

    ...
    Exit Sub
    FileNotFound: If MsgBox("This File Does Not Exist!", vbRetryCancel) = vbCancel Then

    Else: Call Clear

It's a shorthand for <?php echo $a; ?>.

The best one by far is

bool(re.search('ba[rzd]', 'foobarrrr'))

Returns True

Use the title attribute while alt is important for SEO stuff.

On the replacement side, you must use $1, not \1.

And you can only do what you want by making replace an evalable expression that gives the result you want and telling s/// to eval it with the /ee modifier like so:

$find="start (.*) end";
$replace='"foo $1 bar"';

$var = "start middle end";
$var =~ s/$find/$replace/ee;

print "var: $var\n";

To see why the "" and double /e are needed, see the effect of the double eval here:

$ perl
$foo = "middle";
$replace='"foo $foo bar"';
print eval('$replace'), "\n";
print eval(eval('$replace')), "\n";
__END__
"foo $foo bar"
foo middle bar

(Though as ikegami notes, a single /e or the first /e of a double e isn't really an eval(); rather, it tells the compiler that the substitution is code to compile, not a string. Nonetheless, eval(eval(...)) still demonstrates why you need to do what you need to do to get /ee to work as desired.)

You are in project C, project C is submodule of B and B is submodule of A. You try to reach module D's src/test/config/etc directory from project C. D is also submodule of A. The following expression makes this possible to get the URI path:

heres a step by step procedure (assuming you've already installed python):

1. first install chocolatey:

open terminal (Run as Administrator) and type in the command line:

C:/> @powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

it will take some time to get chocolatey installed on your machine. sit back n relax...

2. now install pip. type in terminal cinst easy.install pip

3. now type in terminal: pip install flask

YOU'RE DONE !!! Tested on Win 8.1 with Python 2.7

Actually this error occurs when server makes connection but can't build due to failure in identifying connection function identifier. This problem can be solved by typing connection function in code. For this I take a simple example. In this case function is con your may be different.

SqlCommand cmd = new SqlCommand("insert into ptb(pword,rpword) values(@a,@b)",con);

Start by get the content from file and trim the white spaces if any found in each line of the text document. That becomes the object passed to the where-object to go through the array looking at each member of the array with string length greater then 0. That object is passed to replace the content of the file you started with. It would probably be better to make a new file... Last thing to do is reads back the newly made file's content and see your awesomeness.

The best video playback/encoding library I have ever seen is ffmpeg. It plays everything you throw at it. (It is used by MPlayer.) It is written in C but I found some Java wrappers.

• FFMPEG-Java: A Java wrapper around ffmpeg using JNA.
• jffmpeg: This one integrates to JMF.

If you need to convert the instance of System.Xml.Linq.XDocument into the instance of the System.Xml.XmlDocument this extension method will help you to do not lose the XML declaration in the resulting XmlDocument instance:

using System.Xml; 
using System.Xml.Linq;

namespace www.dimaka.com
{ 
    internal static class LinqHelper 
    { 
        public static XmlDocument ToXmlDocument(this XDocument xDocument) 
        { 
            var xmlDocument = new XmlDocument(); 
            using (var reader = xDocument.CreateReader()) 
            { 
                xmlDocument.Load(reader); 
            }

            var xDeclaration = xDocument.Declaration; 
            if (xDeclaration != null) 
            { 
                var xmlDeclaration = xmlDocument.CreateXmlDeclaration( 
                    xDeclaration.Version, 
                    xDeclaration.Encoding, 
                    xDeclaration.Standalone);

                xmlDocument.InsertBefore(xmlDeclaration, xmlDocument.FirstChild); 
            }

            return xmlDocument; 
        } 
    } 
}

Hope that helps!

I think that would depend on what browser implementation you are refering to.

Every browser type has it's own javascript engine implementation, so it depends. You could check the sourcecode repos for Mozilla and Webkit/Khtml for different implementations.

IE is closed source however, so you may have to ask somebody at microsoft.

You should be using below

return Observable.throw(error || 'Internal Server error');

Import the throw operator using the below line

import 'rxjs/add/observable/throw';

Iterative solution as an alternative:

def traverse_nested_dict(d):
    iters = [d.iteritems()]

    while iters:
        it = iters.pop()
        try:
            k, v = it.next()
        except StopIteration:
            continue

        iters.append(it)

        if isinstance(v, dict):
            iters.append(v.iteritems())
        else:
            yield k, v


d = {"a": 1, "b": 2, "c": {"d": 3, "e": {"f": 4}}}
for k, v in traverse_nested_dict(d):
    print k, v

You can convert the list of passed values into a table valued parameter and then select against this list

DECLARE @list NVARCHAR(MAX)
SET @list = '1,2,5,7,10';

DECLARE @pos INT
DECLARE @nextpos INT
DECLARE @valuelen INT
DECLARE @tbl TABLE (number int NOT NULL)

SELECT @pos = 0, @nextpos = 1;

WHILE @nextpos > 0
BEGIN
    SELECT @nextpos = charindex(',', @list, @pos + 1)
    SELECT @valuelen = CASE WHEN @nextpos > 0
                            THEN @nextpos
                            ELSE len(@list) + 1
                        END - @pos - 1
    INSERT @tbl (number)
        VALUES (convert(int, substring(@list, @pos + 1, @valuelen)))
    SELECT @pos = @nextpos;
END

SELECT * FROM DBTable WHERE id IN (SELECT number FROM @tbl);

In this example the string passed in '1,2,5,7,10' is split by the commas and each value is added as a new row within the @tbl table variable. This can then be selected against using standard SQL.

If you intend to reuse this functionality you could go further and convert this into a function.

[System.Security.Principal.WindowsIdentity]::GetCurrent().Name

When the propagation setting is PROPAGATION_REQUIRED, a logical transaction scope is created for each method upon which the setting is applied. Each such logical transaction scope can determine rollback-only status individually, with an outer transaction scope being logically independent from the inner transaction scope. Of course, in case of standard PROPAGATION_REQUIRED behavior, all these scopes will be mapped to the same physical transaction. So a rollback-only marker set in the inner transaction scope does affect the outer transaction's chance to actually commit (as you would expect it to).

http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/transaction.html

This should work in Bootstrap 4:

$("#my-popover-trigger").popover({_x000D_
  template: '<div class="popover my-popover-content" role="tooltip"><div class="arrow"></div><div class="popover-body"></div></div>',_x000D_
  trigger: "manual"_x000D_
})_x000D_
_x000D_
$(document).click(function(e) {_x000D_
  if ($(e.target).closest($("#my-popover-trigger")).length > 0) {_x000D_
    $("#my-popover-trigger").popover("toggle")_x000D_
  } else if (!$(e.target).closest($(".my-popover-content")).length > 0) {_x000D_
    $("#my-popover-trigger").popover("hide")_x000D_
  }_x000D_
})

Explanation:

• The first section inits the popover as per the docs: https://getbootstrap.com/docs/4.0/components/popovers/
• The first "if" in the second section checks whether the clicked element is a descendant of #my-popover-trigger. If that is true, it toggles the popover (it handles the click on the trigger).
• The second "if" in the second section checks whether the clicked element is a descendant of the popover content class which was defined in the init template. If it is not this means that the click was not inside the popover content, and the popover can be hidden.

For me the following solution worked:

1] Going to BIOS setting and enabling Virtualization.

Here you can find a working example, with some more suggestions about dynamic resizing of the list.

I've used display:inline-block and a percentage padding so that the parent list can dynamically change size:

display:inline-block;
padding:10px 1%;
width: 30%

plus two more rules to remove padding for the first and last items.

ul#menuItems li:first-child{padding-left:0;}
ul#menuItems li:last-child{padding-right:0;}

I wanted it simple just to be able to call gradle bootRunDev like you without having to do any extra typing..

This worked for me - by first configuring it the bootRun in my task and then right after it running bootRun which worked fine for me :)

task bootRunDev {
    bootRun.configure {
        systemProperty "spring.profiles.active", 'Dev'
    }
}

bootRunDev.finalizedBy bootRun

Consider you need to develop a program through which you need to pass two arguments. First of all, you need to open Program.cs class and add arguments in the Main method as like below and pass these arguments to the constructor of the Windows form.

static class Program
{    
   [STAThread]
   static void Main(string[] args)
   {            
       Application.EnableVisualStyles();
       Application.SetCompatibleTextRenderingDefault(false);
       Application.Run(new Form1(args[0], Convert.ToInt32(args[1])));           
   }
}

In windows form class, add a parameterized constructor which accepts the input values from Program class as like below.

public Form1(string s, int i)
{
    if (s != null && i > 0)
       MessageBox.Show(s + " " + i);
}

To test this, you can open command prompt and go to the location where this exe is placed. Give the file name then parmeter1 parameter2. For example, see below

C:\MyApplication>Yourexename p10 5

From the C# code above, it will prompt a Messagebox with value p10 5.

If you want to remove the glow from buttons in Bootstrap (which is not necessarily bad UX in my opinion), you'll need the following code:

.btn:focus, .btn:active:focus, .btn.active:focus{
  outline-color: transparent;
  outline-style: none;
}

You probably need to chdir to the correct directory before calling the script. This way you can ensure what directory your script is "in" before calling the shell command.

$old_path = getcwd();
chdir('/my/path/');
$output = shell_exec('./script.sh var1 var2');
chdir($old_path);

I know this is old, but thought it would be a good idea to update. If an accurate count is needed, then column ECID should probably be filtered as well. A SPID with parallel threads can show up multiple times in sysprocesses and filtering ECID=0 will return the primary thread for each SPID.

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses with (nolock)
WHERE 
    dbid > 0
    and ecid=0
GROUP BY 
    dbid, loginame

char originalString[] = "THESTRINGHASNOSPACES";

    char aux[5];
    int j=0;
    for(int i=0;i<strlen(originalString);i++){
        aux[j] = originalString[i];
        if(j==3){
            aux[j+1]='\0'; 
            printf("%s\n",aux);
            j=0;
        }else{
            j++;
        }
    }

if you use

angularjs

you have just to write the right css in order to frame you div html code

<div 
style="height:51px;width:111px;margin-left:203px;" 
ng-click="nextDetail()">
</div>

JS Code(in your controller):

$scope.nextDetail = function()
{
....
}

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

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

Definitely not the ideal solution, but it's easier for me to understand if I convert the list into tuples and then sort it.

mylist = [[1,2,3,4],[4,5,6,7]]
mylist2 = []
for thing in mylist:
    thing = tuple(thing)
    mylist2.append(thing)
set(mylist2)

I got the same error when I added the applicationinitialization module with lots of initializationpages and deployed it on Azure app. The issue turned out to be duplicate entries in my applicationinitialization module. I din't see any errors in the logs so it was hard to troubleshoot. Below is an example of the error code:

  <configuration>
  <system.webServer>
    <applicationInitialization doAppInitAfterRestart="true" skipManagedModules="true">
      <add initializationPage="/init1.aspx?call=2"/>
      <add initializationPage="/init1.aspx?call=2" />
    </applicationInitialization>
  </system.webServer>

Make sure there are no duplicate entries because those will be treated as duplicate keys which are not allowed and will result in "Cannot add duplicate collection entry" error for web.config.

Here's what I've done:

.resize {
    width: 400px;
    height: auto;
}

.resize {
    width: 300px;
    height: auto;
}

<img class="resize" src="example.jpg"/>

This will keep the image aspect ratio the same.

This is because the className value which you are passing as argument for
forName(String className) method is not found or doesn't exists, or you a re passing the wrong value as the class name. Here is also a link which could help you.

Update

Module not specified

According to the snapshot you have provided this problem is because you have not determined the app module of your project, so I suggest you to choose the app module from configuration. For example:

In JavaScript everything is either a primitive type or an object. Functions are objects — (key value pairs).

When you create a function you create two objects. One object that represents the function itself and the other that represents the prototype of the function.

Function is basically in that sense an object with the properties:

function name, 
arguments length 
and the functional prototype.

So where to set the static property: Two places, either inside the function object or inside the function prototype object.

Here is a snippet that creates that end even instantiates two instances, using the new JavaScript keyword.

function C () { // function_x000D_
  var privateProperty = "42";  _x000D_
  this.publicProperty = "39";  _x000D_
  _x000D_
  this.privateMethod = function(){ _x000D_
   console.log(privateProperty);_x000D_
  };_x000D_
}_x000D_
_x000D_
C.prototype.publicMethod = function () {    _x000D_
  console.log(this.publicProperty);_x000D_
};_x000D_
_x000D_
C.prototype.staticPrototypeProperty = "4";_x000D_
C.staticProperty = "3";_x000D_
_x000D_
_x000D_
var i1 = new C(); // instance 1_x000D_
var i2 = new C(); // instance 2_x000D_
_x000D_
i1.privateMethod();_x000D_
i1.publicMethod();_x000D_
_x000D_
console.log(i1.__proto__.staticPrototypeProperty);_x000D_
i1.__proto__.staticPrototypeProperty = "2";_x000D_
console.log(i2.__proto__.staticPrototypeProperty);_x000D_
_x000D_
console.log(i1.__proto__.constructor.staticProperty);_x000D_
i1.__proto__.constructor.staticProperty = "9";_x000D_
console.log(i2.__proto__.constructor.staticProperty);

The main idea is that instances i1 and i2 are using the same static properties.

You want to use postgresql's replace function:

replace(string text, from text, to text)

for instance :

UPDATE <table> SET <field> = replace(<field>, 'cat', 'dog')

Be aware, though, that this will be a string-to-string replacement, so 'category' will become 'dogegory'. the regexp_replace function may help you define a stricter match pattern for what you want to replace.

A Fibbonacci sequence is one that sums the result of a number when added to the previous result starting with 1.

      so.. 1 + 1 = 2
           2 + 3 = 5
           3 + 5 = 8
           5 + 8 = 13
           8 + 13 = 21

Once we understand what Fibbonacci is, we can begin to break down the code.

public int fibonacci(int n)  {
    if(n == 0)
        return 0;
    else if(n == 1)
      return 1;
   else
      return fibonacci(n - 1) + fibonacci(n - 2);
}

The first if statment checks for a base case, where the loop can break out. The else if statement below that is doing the same, but it could be re-written like so...

    public int fibonacci(int n)  {
        if(n < 2)
             return n;

        return fibonacci(n - 1) + fibonacci(n - 2);
    }

Now that a base case is establish we have to understand the call stack.Your first call to "fibonacci" will be the last to resolve on the stack (sequence of calls) as they resolve in the reverse order from which they were called. The last method called resolves first, then the last to be called before that one and so on...

So, all the calls are made first before anything is "calculated" with those results. With an input of 8 we expect an output of 21 (see table above).

fibonacci(n - 1) keeps being called until it reaches the base case, then fibonacci(n - 2) is called until it reaches the base case. When the stack starts summing the result in reverse order, the result will be like so...

1 + 1 = 1        ---- last call of the stack (hits a base case).
2 + 1 = 3        ---- Next level of the stack (resolving backwards).
2 + 3 = 5        ---- Next level of the stack (continuing to resolve).

They keep bubbling (resolving backwards) up until the correct sum is returned to the first call in the stack and that's how you get your answer.

Having said that, this algorithm is very inefficient because it calculates the same result for each branch the code splits into. A much better approach is a "bottom up" one where no Memoization (caching) or recursion (deep call stack) is required.

Like so...

        static int BottomUpFib(int current)
        {
            if (current < 2) return current;

            int fib = 1;
            int last = 1;

            for (int i = 2; i < current; i++)
            {
                int temp = fib;
                fib += last;
                last = temp;
            }

            return fib;
        }

Hi i am placing here a summary from many sources online for various solutions to "access is denied" : most information can be found here (including requirements needed) - sysinternal help

1. as someone mentioned add this reg key, and then restart the computer :

   reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f

   Read this knowledge base article to learn what this does and why it is needed

2. Disable firewall (note - this will leave you with out any firewall protection)

   netsh advfirewall set allprofiles state off

3. if target user has a blank PW and you dont want to add one, run on target:

   [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa] "LimitBlankPasswordUse"=dword:00000000

4. This didnt work for me, but i have read it did for others in a few places, on target execute:

   Start -> Run -> secpol.msc -> Local Policies -> Security Options -> Network Access: Sharing > and security model for local accounts > Classic – local users authenticate as themselves

   if already in 'Classic':

   move to "Guest only - .." run from elevated command prompt gpupdate \force move back to 'Classic - .." again run from elevated command prompt gpupdate \force

5. This one solved my issue:

   run on target from elevated command prompt "net use" look at ouput chart and for shares listed in remote column there (i only deleted the disconnected ones - you can try them all) run "net use [remote path from before list] /delete" then run 'net use \target\Admin$ /user:[user name]' enter prompt password request (if empty PW just press enter), viola should work.

good luck, hope this saves someones time.

You can do this in Javascript.

var time = new Date();
console.log(time.getHours() + ":" + time.getMinutes() + ":" + time.getSeconds());

At present it returns 15:5:18. Note that if any of the values are less than 10, they will display using only one digit, not two.

Check this in JSFiddle

Updates:
For prefixed 0's try

var time = new Date();
console.log(
    ("0" + time.getHours()).slice(-2)   + ":" + 
    ("0" + time.getMinutes()).slice(-2) + ":" + 
    ("0" + time.getSeconds()).slice(-2));

AssertJ 3.9.1 supports direct predicate usage in anyMatch method.

assertThat(collection).anyMatch(element -> element.someProperty.satisfiesSomeCondition())

This is generally suitable use case for arbitrarily complex condition.

For simple conditions I prefer using extracting method (see above) because resulting iterable-under-test might support value verification with better readability. Example: it can provide specialized API such as contains method in Frank Neblung's answer. Or you can call anyMatch on it later anyway and use method reference such as "searchedvalue"::equals. Also multiple extractors can be put into extracting method, result subsequently verified using tuple().

this is Postgres UPDATE JOIN format:

UPDATE address 
SET cid = customers.id
FROM customers 
WHERE customers.id = address.id

Here's the other variations: http://mssql-to-postgresql.blogspot.com/2007/12/updates-in-postgresql-ms-sql-mysql.html

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.

Example:

INSERT INTO tbl_name
    (a,b,c)
VALUES
    (1,2,3),
    (4,5,6),
    (7,8,9);

I tried to implement the result of Nick which is:

$('.selectorUsedToCreateTheDialog').dialog('option', 'title', 'My New title');

But that didn't work for me because i had multiple dialogs on 1 page. In such a situation it will only set the title correct the first time. Trying to staple commands did not work:

    $("#modal_popup").html(data);
    $("#modal_popup").dialog('option', 'title', 'My New Title');
    $("#modal_popup").dialog({ width: 950, height: 550);

I fixed this by adding the title to the javascript function arguments of each dialog on the page:

function show_popup1() {
    $("#modal_popup").html(data);
    $("#modal_popup").dialog({ width: 950, height: 550, title: 'Popup Title of my First Dialog'});
}

function show_popup2() {
    $("#modal_popup").html(data);
    $("#modal_popup").dialog({ width: 950, height: 550, title: 'Popup Title of my Other Dialog'});
}

The syntax for index hints is documented here:
http://dev.mysql.com/doc/refman/5.6/en/index-hints.html

FORCE INDEX goes right after the table reference:

SELECT * FROM (
    SELECT owner_id,
           product_id,
           start_time,
           price,
           currency,
           name,
           closed,
           active,
           approved,
           deleted,
           creation_in_progress
    FROM db_products FORCE INDEX (products_start_time)
    ORDER BY start_time DESC
) as resultstable
WHERE resultstable.closed = 0
      AND resultstable.active = 1
      AND resultstable.approved = 1
      AND resultstable.deleted = 0
      AND resultstable.creation_in_progress = 0
GROUP BY resultstable.owner_id
ORDER BY start_time DESC

WARNING:

If you're using ORDER BY before GROUP BY to get the latest entry per owner_id, you're using a nonstandard and undocumented behavior of MySQL to do that.

There's no guarantee that it'll continue to work in future versions of MySQL, and the query is likely to be an error in any other RDBMS.

Search the greatest-n-per-group tag for many explanations of better solutions for this type of query.

The library PCAmixdata has functon splitmix that splits quantitative(Numerical data) and qualitative (Categorical data) of a given dataframe "YourDataframe" as shown below:

install.packages("PCAmixdata")
library(PCAmixdata)
split <- splitmix(YourDataframe)
X1 <- split$X.quanti(Gives numerical columns in the dataset) 
X2 <- split$X.quali (Gives categorical columns in the dataset)

One simplest way to encounter this is to use font awesome for example

 <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
       <span><i class="fas fa-bars"></i></span>
</button>

Then u can change the i element like you change any other ielement.

Since I have recently developed an Android application using gyroscope data (steady compass), I tried to collect a list with such devices. This is not an exhaustive list at all, but it is what I have so far:

*** Phones:

• HTC Sensation
• HTC Sensation XL
• HTC Evo 3D
• HTC One S
• HTC One X
• Huawei Ascend P1
• Huawei Ascend X (U9000)
• Huawei Honor (U8860)
• LG Nitro HD (P930)
• LG Optimus 2x (P990)
• LG Optimus Black (P970)
• LG Optimus 3D (P920)
• Samsung Galaxy S II (i9100)
• Samsung Galaxy S III (i9300)
• Samsung Galaxy R (i9103)
• Samsung Google Nexus S (i9020)
• Samsung Galaxy Nexus (i9250)
• Samsung Galaxy J3 (2017) model
• Samsung Galaxy Note (n7000)
• Sony Xperia P (LT22i)
• Sony Xperia S (LT26i)

*** Tablets:

• Acer Iconia Tab A100 (7")
• Acer Iconia Tab A500 (10.1")
• Asus Eee Pad Transformer (TF101)
• Asus Eee Pad Transformer Prime (TF201)
• Motorola Xoom (mz604)
• Samsung Galaxy Tab (p1000)
• Samsung Galaxy Tab 7 plus (p6200)
• Samsung Galaxy Tab 10.1 (p7100)
• Sony Tablet P
• Sony Tablet S
• Toshiba Thrive 7"
• Toshiba Trhive 10"

Hope the list keeps growing and hope that gyros will be soon available on mid and low price smartphones.

I have seen two reasons behind this issue

1) access key does not have the right permission. pem keys with default permission are not allowed to make a secure connection. You just have to change the permission:

chmod 400 xyz.pem

2) Also check whether you have logged-in with proper user credentials. Otherwise, use sudo while connecting

sudo ssh -i {keyfile} ec2-user@{ip address of remote host}

You can use it via LINQ

     var selectedEditionIds = input.SelectedEditionIds.Split(",").ToArray()
                            .Where(i => !string.IsNullOrWhiteSpace(i) 
                             && int.TryParse(i,out int validNumber))
                            .Select(x=>int.Parse(x)).ToList();

enter code hereCreate script file with below gradle and adb command, Execute script file

./gradlew clean

./gradlew assembleDebug ./gradlew installDebug

adb shell am start -n applicationID/full path of launcher activity

Use a list comprehension:

res_list = [x[0] for x in rows]

Below is a demonstration:

>>> rows = [(1, 2), (3, 4), (5, 6)]
>>> [x[0] for x in rows]
[1, 3, 5]
>>>

Alternately, you could use unpacking instead of x[0]:

res_list = [x for x,_ in rows]

Below is a demonstration:

>>> lst = [(1, 2), (3, 4), (5, 6)]
>>> [x for x,_ in lst]
[1, 3, 5]
>>>

Both methods practically do the same thing, so you can choose whichever you like.

You can achieve that by using positioning.

Try

position: absolute;

to get the 100% height.

Here's the filter that I ended up using for strftime in Jinja2 and Flask

@app.template_filter('strftime')
def _jinja2_filter_datetime(date, fmt=None):
    date = dateutil.parser.parse(date)
    native = date.replace(tzinfo=None)
    format='%b %d, %Y'
    return native.strftime(format) 

And then you use the filter like so:

{{car.date_of_manufacture|strftime}}

You can try this

var lastPostDate = reader[3] == DBNull.Value ?
                                default(DateTime?): 
                                Convert.ToDateTime(reader[3]);

To check if any module in a project is 'old':

npm outdated

'outdated' will check every module defined in package.json and see if there is a newer version in the NPM registry.

For example, say xml2js 0.2.6 (located in node_modules in the current project) is outdated because a newer version exists (0.2.7). You would see:

[email protected] node_modules/xml2js current=0.2.6

To update all dependencies, if you are confident this is desirable:

npm update

Or, to update a single dependency such as xml2js:

npm update xml2js

No offence, but none of the other answers (so far) has it quite right.

break is used to immediately terminate a for loop, a while loop or a switch statement. You can not break from an if block.

return is used the terminate a method (and possibly return a value).

A return within any loop or block will of course also immediately terminate that loop/block.

java.io.DataInput.readUTF() and java.io.DataOutput.writeUTF(String) say that a String object is represented by two bytes of length information and the modified UTF-8 representation of every character in the string. This concludes that the length of String is limited by the number of bytes of the modified UTF-8 representation of the string when used with DataInput and DataOutput.

In addition, The specification of CONSTANT_Utf8_info found in the Java virtual machine specification defines the structure as follows.

CONSTANT_Utf8_info {
    u1 tag;
    u2 length;
    u1 bytes[length];
}

You can find that the size of 'length' is two bytes.

That the return type of a certain method (e.g. String.length()) is int does not always mean that its allowed maximum value is Integer.MAX_VALUE. Instead, in most cases, int is chosen just for performance reasons. The Java language specification says that integers whose size is smaller than that of int are converted to int before calculation (if my memory serves me correctly) and it is one reason to choose int when there is no special reason.

The maximum length at compilation time is at most 65536. Note again that the length is the number of bytes of the modified UTF-8 representation, not the number of characters in a String object.

String objects may be able to have much more characters at runtime. However, if you want to use String objects with DataInput and DataOutput interfaces, it is better to avoid using too long String objects. I found this limitation when I implemented Objective-C equivalents of DataInput.readUTF() and DataOutput.writeUTF(String).

<?php
$a= array("1","2","3");
print_r($a);
$b=serialize($a);

Run this program its echo the output

a:3:{i:0;s:1:"1";i:1;s:1:"2";i:2;s:1:"3";}

you can use serialize to store array of data in database
and can retrieve and UN-serialize data to use.

Basically you have two options

scale_x_continuous(limits = c(-5000, 5000))

or

coord_cartesian(xlim = c(-5000, 5000)) 

Where the first removes all data points outside the given range and the second only adjusts the visible area. In most cases you would not see the difference, but if you fit anything to the data it would probably change the fitted values.

You can also use the shorthand function xlim (or ylim), which like the first option removes data points outside of the given range:

+ xlim(-5000, 5000)

For more information check the description of coord_cartesian.

The RStudio cheatsheet for ggplot2 makes this quite clear visually. Here is a small section of that cheatsheet:

One way would be to first flatten the list with a SelectMany:

subList.SelectMany(m => m).Where(k => k.Key.Equals("valueTitle"));

This is the way i calculated the slope: Source: http://classroom.synonym.com/calculate-trendline-2709.html

class Program
    {
        public double CalculateTrendlineSlope(List<Point> graph)
        {

            double c = 0;
            double d = 0;
            double slope = 0;

            foreach (Point point in graph)
            {
                a += point.x * point.y;
                bx = point.x;
                by = point.y;
                c += Math.Pow(point.x, 2);

I found the information found at http://help.infragistics.com/Help/NetAdvantage/jQuery/2013.1/CLR4.0/html/igOlapXmlaDataSource_Configuring_IIS_for_Cross_Domain_OLAP_Data.html to be very helpful in setting up HTTP OPTIONS for a WCF service in IIS 7.

I added the following to my web.config and then moved the OPTIONSVerbHandler in the IIS 7 'hander mappings' list to the top of the list. I also gave the OPTIONSVerbHander read access by double clicking the hander in the handler mappings section then on 'Request Restrictions' and then clicking on the access tab.

Unfortunately I quickly found that IE doesn't seem to support adding headers to their XDomainRequest object (setting the Content-Type to text/xml and adding a SOAPAction header).

Just wanted to share this as I spent the better part of a day looking for how to handle it.

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <add name="Access-Control-Allow-Origin" value="*" />
            <add name="Access-Control-Allow-Methods" value="GET,POST,OPTIONS" />
            <add name="Access-Control-Allow-Headers" value="Content-Type, soapaction" />
        </customHeaders>
    </httpProtocol>
</system.webServer>

eg. you can use

android:maxLength="13"

this will restrict texview length to 13 but problem is if you try to add 3 dots(...), it wont display it, as it will be part of textview length.

     String userName;
     if (data.length() >= 13) {
            userName = data.substring(0, 13)+ "...";

     } else {

            userName = data;

    }
        textView.setText(userName);

apart from this you have to use

 android:maxLines="1"

If you're using PHP5.3 or above, you can use numfmt_parse to do "a reversed number_format". If you're not, you stuck with replacing the occurrances with preg_replace/str_replace.

When filtering a DataFrame with string values, I find that the pyspark.sql.functions lower and upper come in handy, if your data could have column entries like "foo" and "Foo":

import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))

Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.

ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.

The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).

A better option

Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses (and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.

As mentioned, for efficiency reasons sequential spaces are consolidated into one space the browser actually displays. Remember what the ML in HTML stand for. It's a Mark-up Language, designed to control how text is displayed.. not whitespace :p

Still, you can pretend the browser respects tabs since all the TAB does is prepend 4 spaces, and that's easy with CSS. either in line like ...

 <div style="padding-left:4.00em;">Indenented text </div>

Or as a regular class in a style sheet

.tabbed {padding-left:4.00em;}

Then the HTML might look like

<p>regular paragraph regular paragraph regular paragraph</p>
<p class="tabbed">Indented text Indented text Indented text</p>
<p>regular paragraph regular paragraph regular paragraph</p>

I found it easier without Visual Tree Helpers:

foreach (UIElement element in MainWindow.Children) {
    if (element is TextBox) { 
        if ((element as TextBox).Text != "")
        {
            //Do something
        }
    }
};

@gerrit_hoekstra wrote: "However, the value of an auto-increment field is only available to an "AFTER-INSERT" trigger - it defaults to 0 in the BEFORE-case."

That is correct but you can select the auto-increment field value that will be inserted by the subsequent INSERT quite easily. This is an example that works:

CREATE DEFINER = CURRENT_USER TRIGGER `lgffin`.`variable_BEFORE_INSERT` BEFORE INSERT 
ON `variable` FOR EACH ROW
BEGIN
    SET NEW.prefixed_id = CONCAT(NEW.fixed_variable, (SELECT `AUTO_INCREMENT`
                                                FROM  INFORMATION_SCHEMA.TABLES
                                                WHERE TABLE_SCHEMA = 'lgffin'
                                                AND   TABLE_NAME   = 'variable'));      
END

There's also workaround doing disjunction of your array, worked for me as other solutions were hard to implement using some old framework.

select * from tableA where id = 1 or id = 2 or id = 3 ...

But for better perfo, I would use Nikolai Nechai's solution with unions, if possible.

Just put your Images in Public Directory (public/...folder or direct images).
Public directory is by default rendered by laravel application.
Let's suppose I stored images in public/images/myimage.jpg.
Then in your HTML view, page like: (image.blade.php)

<img src="{{url('/images/myimage.jpg')}}" alt="Image"/>

Without knowing more about the problem domain, it's hard to answer your question. Unless you are certain that you need to do something more, the pythonic way to initialize a list is:

verts = []

Are you actually seeing a performance problem? If so, what is the performance bottleneck? Don't try to solve a problem that you don't have. It's likely that performance cost to dynamically fill an array to 1000 elements is completely irrelevant to the program that you're really trying to write.

The array class is useful if the things in your list are always going to be a specific primitive fixed-length type (e.g. char, int, float). But, it doesn't require pre-initialization either.

git rev-parse Also works for getting the current branch name using the --abbrev-ref flag like:

git rev-parse --abbrev-ref HEAD

You can also do this:

wget -O - https://raw.github.com/luismartingil/commands/master/101_remote2local_wireshark.sh | bash

Toastr is a very nice component, and you can show messages with theses commands:

// for success - green box
toastr.success('Success messages');

// for errors - red box
toastr.error('errors messages');

// for warning - orange box
toastr.warning('warning messages');

// for info - blue box
toastr.info('info messages');

If you want to provide a title on the toastr message, just add a second argument:

// for info - blue box
toastr.success('The process has been saved.', 'Success');

you also can change the default behaviour using something like this:

toastr.options.timeOut = 3000; // 3s

See more on the github of the project.

Edits

A sample of use:

$(document).ready(function() {

    // show when page load
    toastr.info('Page Loaded!');

    $('#linkButton').click(function() {
       // show when the button is clicked
       toastr.success('Click Button');

    });

});

and a html:

<a id='linkButton'>Show Message</a>

This will give you one last document for a collection

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

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

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

You dont have a function named assign(), but a method with this name. PHP is not Java and in PHP you have to make clear, if you want to call a function

assign()

or a method

$object->assign()

In your case the call to the function resides inside another method. $this always refers to the object, in which a method exists, itself.

$this->assign()

navigate to the folder where you have installed your kibana if you have used yum to install kibana it will be placed in following location by default

/usr/share/kibana

then use the following command

bin/kibana --version

There's a nice example of try-else in PEP 380. Basically, it comes down to doing different exception handling in different parts of the algorithm.

It's something like this:

try:
    do_init_stuff()
except:
    handle_init_suff_execption()
else:
    try:
        do_middle_stuff()
    except:
        handle_middle_stuff_exception()

This allows you to write the exception handling code nearer to where the exception occurs.

var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?foo=bar';
window.history.pushState({path:newurl},'',newurl);

Old post I know. Whatever the orientation may be or is swapped etc. I designed this function that is used to set the device in the right orientation without the need to know how the portrait and landscape features are organised on the device.

   private void initActivityScreenOrientPortrait()
    {
        // Avoid screen rotations (use the manifests android:screenOrientation setting)
        // Set this to nosensor or potrait

        // Set window fullscreen
        this.activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        DisplayMetrics metrics = new DisplayMetrics();
        this.activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

         // Test if it is VISUAL in portrait mode by simply checking it's size
        boolean bIsVisualPortrait = ( metrics.heightPixels >= metrics.widthPixels ); 

        if( !bIsVisualPortrait )
        { 
            // Swap the orientation to match the VISUAL portrait mode
            if( this.activity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT )
             { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); }
            else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT ); }
        }
        else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); }

    }

Works like a charm!

The url portion of a request (GET and POST) can be limited by both the browser and the server - generally the safe size is 2KB as there are almost no browsers or servers that use a smaller limit.

The body of a request (POST) is normally* limited by the server on a byte size basis in order to prevent a type of DoS attack (note that this means character escaping can increase the byte size of the body). The most common server setting is 10MB, though all popular servers allow this to be increased or decreased via a setting file or panel.

*Some exceptions exist with older cell phone or other small device browsers - in those cases it is more a function of heap space reserved for this purpose on the device then anything else.

You have mixed indentation formatting (spaces and tabs)

On Notepad++

Change Tab Settings to 4 spaces

Go to Settings -> Preferences -> Tab Settings -> Replace by spaces

Fix the current file mixed indentations

Select everything CTRL+A

Click TAB once, to add an indentation everywhere

Run SHIFT + TAB to remove the extra indentation, it will replace all TAB characters to 4 spaces.

You can also split a string at every n-th character and put them each, in each index of a List :

Here I made a list of Strings named Sequence :

List < String > Sequence

Then I'm basically splitting the String "KILOSO" by every 2 words. So 'KI' 'LO' 'SO' would be incorporate in separate index of the List called Sequence.

String S = KILOSO

Sequence = Arrays.asList(S.split("(?<=\G..)"));

So when I'm doing :

System.out.print(Sequence)

It should print :

[KI, LO, SO]

to verify I can write :

System.out.print(Sequence.get(1))

it will print :

LO

If your components are global you can simply do:

var nameOfComponent = "SomeComponent";_x000D_
React.createElement(window[nameOfComponent], {});

Just cast the int to the enumeration type:

EnumDisplayStatus status = (EnumDisplayStatus) statusFromDatabase;
string statusString = status.ToString();

Updating NodeJS solves this problem. But, after running sudo npm install -g n you might get following error:

npm: relocation error: npm: symbol SSL_set_cert_cb, version libssl.so.10 not defined in file libssl.so.10 with link time reference

In order to overcome this error, try upgrading openssl using the below command:

sudo yum update openssl

You are making it complicated. string is already nullable. You don't need to make it more nullable. Take out the ? on the property type.

As stated by Taylor L, you can't just "stop" a thread (by calling a simple method) due to the fact that it could leave your system in an unstable state as the external calling thread may not know what is going on inside your thread.

With this said, the best way to "stop" a thread is to have the thread keep an eye on itself and to have it know and understand when it should stop.

Try quoting the argument list:

Start-Process -FilePath "C:\Program Files\MSBuild\test.exe" -ArgumentList "/genmsi/f $MySourceDirectory\src\Deployment\Installations.xml"

You can also provide the argument list as an array (comma separated args) but using a string is usually easier.

Your code as it stands is correct but I am having a hard time figuring out how it could/would be used in a real world scenario. With that said, please be aware of a few caveats when returning pointers from functions:

• When you create an array with syntax int arr[5];, it's allocated on the stack and is local to the function.
• C++ allows you to return a pointer to this array, but it is undefined behavior to use the memory pointed to by this pointer outside of its local scope. Read this great answer using a real world analogy to get a much clear understanding than what I could ever explain.
• You can still use the array outside the scope if you can guarantee that memory of the array has not be purged. In your case this is true when you pass arr to test().
• If you want to pass around pointers to a dynamically allocated array without worrying about memory leaks, you should do some reading on std::unique_ptr/std::shared_ptr<>.

Edit - to answer the use-case of matrix multiplication

You have two options. The naive way is to use std::unique_ptr/std::shared_ptr<>. The Modern C++ way is to have a Matrix class where you overload operator * and you absolutely must use the new rvalue references if you want to avoid copying the result of the multiplication to get it out of the function. In addition to having your copy constructor, operator = and destructor, you also need to have move constructor and move assignment operator. Go through the questions and answers of this search to gain more insight on how to achieve this.

Edit 2 - answer to appended question

int* test (int a[5], int b[5]) {
    int *c = new int[5];
    for (int i = 0; i < 5; i++) c[i] = a[i]+b[i];
    return c;
}

If you are using this as int *res = test(a,b);, then sometime later in your code, you should call delete []res to free the memory allocated in the test() function. You see now the problem is it is extremely hard to manually keep track of when to make the call to delete. Hence the approaches on how to deal with it where outlined in the answer.

for i in range(len(list)): list[i]=float(list[i])

Had same issue this end of week, only Firefox will not accept certificate... The solution for me has been to add, in the apache configuration of the website, the intermediate certificate with the following line :

SSLCACertificateFile /your/path/to/ssl_ca_certs.pem

Find more infomration on https://httpd.apache.org/docs/2.4/fr/mod/mod_ssl.html

Another gotcha I recently came across is that in IE 8, "abcd".substr(-1) erroneously returns "abcd", whereas Firefox 3.6 returns "d" as it should. slice works correctly on both.

More on this topic can be found here.

Its a little tricky one, check this whether it is working for you

select a.id,if(a.parent = 0,@varw:=concat(a.id,','),@varw:=concat(a.id,',',@varw)) as list from (select * from recursivejoin order by if(parent=0,id,parent) asc) a left join recursivejoin b on (a.id = b.parent),(select @varw:='') as c  having list like '%19,%';

Replace with your field and table name appropriately.

The selected answer doesn't always ensure that HTML is stripped, as it's still possible to construct an invalid HTML string through it by crafting a string like the following.

  "<<h1>h1>foo<<//</h1>h1/>"

This input will ensure that the stripping assembles a set of tags for you and will result in:

  "<h1>foo</h1>"

additionally jquery's text function will strip text not surrounded by tags.

Here's a function that uses jQuery but should be more robust against both of these cases:

var stripHTML = function(s) {
    var lastString;

    do {            
        s = $('<div>').html(lastString = s).text();
    } while(lastString !== s) 

    return s;
};

You can sort a map by value as below, more example here

//Sort a Map by their Value.
Map<Integer, String> random = new HashMap<Integer, String>();

random.put(1,"z");
random.put(6,"k");
random.put(5,"a");
random.put(3,"f");
random.put(9,"c");

Map<Integer, String> sortedMap =
        random.entrySet().stream()
                .sorted(Map.Entry.comparingByValue())
                .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue,
                        (e1, e2) -> e2, LinkedHashMap::new));
System.out.println("Sorted Map: " + Arrays.toString(sortedMap.entrySet().toArray()));

Why don't use GUID?

Guid guid = Guid.NewGuid();
string str = guid.ToString();

Highlight the lines and use:

• Windows: Ctrl+Shift+L
• Mac: Cmd ?+Shift+L

You can then move the cursor to your heart's content and edit all lines at once.

It's also called "Split into Lines" in the "Selection" menu.

<meta charset='utf-8'> overrides the apache default charset (cf /etc/apache2/conf.d/charset)

If this is not enough, then you probably created your original file with iso-8859-1 encoding character set. You have to convert it to the proper character set:

iconv -f ISO-8859-1 -t UTF-8 source_file.php -o new file.php

A general answer that I composed from your answers and from other links and it worked for me and I wrote it in a comment is:

 UPDATE FOO set FIELD2 = TRIM(Replace(Replace(Replace(FIELD2,'\t',''),'\n',''),'\r',''));

etc.

Because trim() doesn't remove all the white spaces so it's better to replace all the white spaces u want and than trim it.

Hope I could help you with sharing my answer :)

Using ints.sum() has two problems:

• The variable is called customerssalary, not ints
• C# is case sensitive - the method is called Sum(), not sum().

Additionally, you'll need a using directive of

using System.Linq;

Once you've got the sum, you can just divide by the length of the array to get the average - you don't need to use Average() which will iterate over the array again.

int sum = customerssalary.Sum();
int average = sum / customerssalary.Length;

or as a double:

double average = ((double) sum) / customerssalary.Length;

Correct, when you drag a view controller object onto your storyboard in order to create a new scene, it doesn't automatically make the new class for you, too.

Having added a new view controller scene to your storyboard, you then have to:

1. Create a UIViewController subclass. For example, go to your target's folder in the project navigator panel on the left and then control-click and choose "New File...". Choose a "Cocoa Touch Class":

   

   And then select a unique name for the new view controller subclass:

   

2. Specify this new subclass as the base class for the scene you just added to the storyboard.

   

3. Now hook up any IBOutlet and IBAction references for this new scene with the new view controller subclass.

For Chart.js 2.*, the option for the scale to begin at zero is listed under the configuration options of the linear scale. This is used for numerical data, which should most probably be the case for your y-axis. So, you need to use this:

options: {
    scales: {
        yAxes: [{
            ticks: {
                beginAtZero: true
            }
        }]
    }
}

A sample line chart is also available here where the option is used for the y-axis. If your numerical data is on the x-axis, use xAxes instead of yAxes. Note that an array (and plural) is used for yAxes (or xAxes), because you may as well have multiple axes.

As Jeppe Stig Nielsen said, this thread already has great answers, but I thought this rather obvious subtlety was worth mentioning too.

using directives specified inside namespaces can make for shorter code since they don't need to be fully qualified as when they're specified on the outside.

The following example works because the types Foo and Bar are both in the same global namespace, Outer.

Presume the code file Foo.cs:

namespace Outer.Inner
{
    class Foo { }
}

And Bar.cs:

namespace Outer
{
    using Outer.Inner;

    class Bar
    {
        public Foo foo;
    }
}

That may omit the outer namespace in the using directive, for short:

namespace Outer
{
    using Inner;

    class Bar
    {
        public Foo foo;
    }
}

Java is supposed to clear the heap space for you when all of the objects are no longer referenced. It won't generally release it back to the OS though, it will keep that memory for it's own internal reuse. Maybe check to see if you have some arrays which are not being cleared or something.

This is about recent additions to AngularJS, to serve as future answer (also for another question).

Angular newer versions (now in 1.3 beta), AngularJS natively supports this option, using ngModelOptions, like

ng-model-options="{ updateOn: 'default blur', debounce: { default: 500, blur: 0 } }"

NgModelOptions docs

Example:

<input type="text" name="username"
       ng-model="user.name"
       ng-model-options="{updateOn: 'default blur', debounce: {default: 500, blur: 0} }" />

This error also occurs when using an IDependencyResolver, such as when using an IoC container, and the dependency resolver returns null. In this case ASP.NET MVC 3 defaults to using the DefaultControllerActivator to create the object. If the object being created does not have a public no-args constructor an exception will then be thrown any time the provided dependency resolver has returned null.

Here's one such stack trace:

Simply add style="line-height:0" to each cell. This works in IE because it sets the line-height of both existant and non-existant text to about 19px and that forces the cells to expand vertically in most versions of IE. Regardless of whether or not you have text this needs to be done for IE to correctly display rows less than 20px high.

No, abstract class can never be instantiated.

Another option is the CONCAT command:

SELECT CONCAT(MyTable.TextColumn, 'Text') FROM MyTable

Having Clause is the easiest way to find duplicate entry in Oracle and using rowid we can remove duplicate data..

DELETE FROM products WHERE rowid IN (
  SELECT MAX(sl) FROM (
  SELECT itemcode, (rowid) sl FROM products WHERE itemcode IN (
  SELECT itemcode FROM products GROUP BY itemcode HAVING COUNT(itemcode)>1
)) GROUP BY itemcode);

The date filter always formats the dates using the local timezone. You'll have to write your own filter, based on the getUTCXxx() methods of Date, or on a library like moment.js.

Do configure --help and see what other options are available.

It is very common to provide different options to override different locations. By standard, --prefix overrides all of them, so you need to override config location after specifying the prefix. This course of actions usually works for every automake-based project.

The worse case scenario is when you need to modify the configure script, or even worse, generated makefiles and config.h headers. But yeah, for Xfce you can try something like this:

./configure --prefix=/home/me/somefolder/mybuild/output/target --sysconfdir=/etc 

I believe that should do it.

I had 2 model properties like this

public int LinkId {get;set;}
public int LinkID {get;set;}

it is strange that it threw this error for these 2 haha..

(can't comment or I would just do that) I believe the suggestion to check locals above is not quite right. It should be:

foo = foo if 'foo' in locals() or 'foo' in globals() else 'default'

to be correct in all contexts.

However, despite its upvotes, I don't think even that is a good analog to the Ruby operator. Since the Ruby operator allows more than just a simple name on the left:

foo[12] ||= something
foo.bar ||= something

The exception method is probably closest analog.

For example, let's say that you want to create a random number between 50 and 60, you can use one of the following methods.

new Random().nextInt()%6 +55

new Random().nextInt()%6 returns a value between -5 and 5. and when you add it to 55 you can get values between 50 and 60

Second method:

Math.abs(new Random().nextInt()%11) +50

Math.abs(new Random().nextInt()%11) creates a value between 0 and 10. Later you can add 50 which in the will give you a value between 50 and 60

Analytics! This avoids having to access the table twice:

SELECT DISTINCT
       FIRST_VALUE(date_col)  OVER (ORDER BY value_col DESC, date_col ASC),
       FIRST_VALUE(value_col) OVER (ORDER BY value_col DESC, date_col ASC)
FROM   mytable;

Just simply use this:

String primary_sd = System.getenv("EXTERNAL_STORAGE");
if(primary_sd != null)
    Log.i("EXTERNAL_STORAGE", primary_sd);
String secondary_sd = System.getenv("SECONDARY_STORAGE");
if(secondary_sd != null)
    Log.i("SECONDARY_STORAGE", secondary_sd)

Maybe you can try the following :

var i = 0;
function AjaxSendForm(url, placeholder, form, append) {
var data = $(form).serialize();
append = (append === undefined ? false : true); // whatever, it will evaluate to true or false only
$.ajax({
    type: 'POST',
    url: url,
    data: data,
    beforeSend: function() {
        // setting a timeout
        $(placeholder).addClass('loading');
        i++;
    },
    success: function(data) {
        if (append) {
            $(placeholder).append(data);
        } else {
            $(placeholder).html(data);
        }
    },
    error: function(xhr) { // if error occured
        alert("Error occured.please try again");
        $(placeholder).append(xhr.statusText + xhr.responseText);
        $(placeholder).removeClass('loading');
    },
    complete: function() {
        i--;
        if (i <= 0) {
            $(placeholder).removeClass('loading');
        }
    },
    dataType: 'html'
});
}

This way, if the beforeSend statement is called before the complete statement i will be greater than 0 so it will not remove the class. Then only the last call will be able to remove it.

I cannot test it, let me know if it works or not.

I have encountered similar problem. The root cause is that (use your scenario for my case), in the #temp table, there is no record for
a. CLASS=RICE and STATE=TX
b. CLASS=VEGIE and (STATE=AZ or STATE=CA)
So, when MSSQL does pivot for no record, MSSQL always shows NULL for MAX, SUM, ... (aggregate functions)

None of above solutions (IsNull([AZ], 0)) works for me. But I do get ideas from these solutions. Thanks.

Sorry, it really depends on the #TEMP table. I can only provide some suggestions.
1. Make sure #TEMP table have records for below condition, even Data is null.
a. CLASS=RICE and STATE=TX
b. CLASS=VEGIE and (STATE=AZ or STATE=CA) You may need to use cartesian product: select A.*, B.* from A, B 2. In the select query for #temp, if you need to join any table with WHERE, then would better put where inside another sub select query. (Goal is 1.)
3. Use isnull(DATA, 0) in #TEMP table.
4. Before pivot, make sure you have achieved Goal 1.

I can't give an answer to the orginal question, since there is no enough info for #temp table. I have pasted my code as example here, hope this will help others.

SELECT * FROM (_x000D_
   SELECT eeee.id as enterprise_id_x000D_
   , eeee.name AS enterprise_name_x000D_
   , eeee.indicator_name_x000D_
   , CONVERT(varchar(12) , isnull(eid.[date],'2019-12-01') , 23) AS data_date_x000D_
   , isnull(eid.value,0) AS indicator_value_x000D_
   FROM (select ei.id as indicator_id, ei.name as indicator_name, e.* FROM tbl_enterprise_indicator ei, tbl_enterprise e) eeee            _x000D_
   LEFT JOIN  (select * from tbl_enterprise_indicator_data WHERE [date]='2020-01-01') eid_x000D_
     ON  eeee.id = eid.enterprise_id and eeee.indicator_id = enterprise_indicator_id_x000D_
  ) AS P _x000D_
  PIVOT _x000D_
  (_x000D_
   SUM(P.indicator_value) FOR P.indicator_name IN(TX,CA)_x000D_
  ) AS T 

You can drop the database and then recreate it with the below:-

mysql> drop database [database name];
mysql> create database [database name];

How to remove NaN (float) item(s) from a list of mixed data types

If you have mixed types in an iterable, here is a solution that does not use numpy:

from math import isnan

Z = ['a','b', float('NaN'), 'd', float('1.1024')]

[x for x in Z if not (
                      type(x) == float # let's drop all float values…
                      and isnan(x) # … but only if they are nan
                      )]

['a', 'b', 'd', 1.1024]

Short-circuit evaluation means that isnan will not be called on values that are not of type 'float', as False and (…) quickly evaluates to False without having to evaluate the right-hand side.

If you do not want changes in one list to effect another list try this.It worked for me
Hope this helps.

  public class MainClass {
  public static void main(String[] a) {

    List list = new ArrayList();
    list.add("A");

    List list2 = ((List) ((ArrayList) list).clone());

    System.out.println(list);
    System.out.println(list2);

    list.clear();

    System.out.println(list);
    System.out.println(list2);
  }

sudo sh -c "echo MY_GLOBAL_ENV_TO_MY_CURRENT_DIR=$(pwd)" >> /etc/environment"

• Add scheduled job to start a script

If you want all packages in that repository, use ... to signify that, like:

go get code.google.com/p/go.text/...

Your convention seems to be reasonable. If I were searching for your framework in the Maven repo, I would look for awesome-inhouse-framework-x.y.jar in com.mycompany.awesomeinhouseframework group directory. And I would find it there according to your convention.

Two simple rules work for me:

• reverse-domain-packages for groupId (since such are quite unique) with all the constrains regarding Java packages names
• project name as artifactId (keeping in mind that it should be jar-name friendly i.e. not contain characters that maybe invalid for a file name or just look weird)

I needed to do the following...

def delete_bucket
  s3 = init_amazon_s3
  s3.buckets['BUCKET-NAME'].objects.each do |obj|
    obj.delete
  end
end

def init_amazon_s3
  config = YAML.load_file("#{Rails.root}/config/s3.yml")
  AWS.config(:access_key_id => config['access_key_id'],:secret_access_key => config['secret_access_key'])
  s3 = AWS::S3.new
end

While this isn't exactly specific to jQuery selectors/objects, in FireFox Quantum 58.x, you can find event handlers on an element using the Dev tools:

1. Right-click the element
2. In the context menu, Click 'Inspect Element'
3. If there is an 'ev' icon next to the element (yellow box), click on 'ev' icon
4. Displays all events for that element and event handler

Though this is an old thread, i thought if someone is still searching for solution in the future.

HttpCookie mycookie = new HttpCookie("aa");
mycookie.Expires = DateTime.Now.AddDays(-1d);
Response.Cookies.Add(mycookie1);

Thats what did the trick for me.

None of the answers at this time are reasonable. Sounds like there is enough demand that a real solution should be proposed: https://github.com/git/git/blob/master/Documentation/SubmittingPatches

git --uncommit <file name>

would be nice. I get that we do not want to modify history, but if I am local and accidentally added local "hack" file and want to remove it from the commit this would be super helpful.

Buttons like <button>Click to do something</button> are submit buttons.

Set type="button" to change that. type="submit" is the default (as specified by the HTML recommendation).

Be aware that there is org.codehaus.jackson.annotate.JsonProperty in Jackson 1.x and com.fasterxml.jackson.annotation.JsonProperty in Jackson 2.x. Check which ObjectMapper you are using (from which version), and make sure you use the proper annotation.

$lookup (aggregation)

Performs a left outer join to an unsharded collection in the same database to filter in documents from the “joined” collection for processing. To each input document, the $lookup stage adds a new array field whose elements are the matching documents from the “joined” collection. The $lookup stage passes these reshaped documents to the next stage. The $lookup stage has the following syntaxes:

Equality Match

To perform an equality match between a field from the input documents with a field from the documents of the “joined” collection, the $lookup stage has the following syntax:

{
   $lookup:
     {
       from: <collection to join>,
       localField: <field from the input documents>,
       foreignField: <field from the documents of the "from" collection>,
       as: <output array field>
     }
}

The operation would correspond to the following pseudo-SQL statement:

SELECT *, <output array field>
FROM collection
WHERE <output array field> IN (SELECT <documents as determined from the pipeline>
                               FROM <collection to join>
                               WHERE <pipeline> );

Mongo URL

background-image takes an url as a value. Use either

background-image: url ('/image/btn.png');

or

background: url ('/image/btn.png') no-repeat;

which is a shorthand for

background-image: url ('/image/btn.png');
background-repeat: no-repeat;

Also, you might want to look at the button HTML element for fancy submit buttons.

Hope this helps.

mTitleView.setOnClickListener(null) should do the trick.

A better design might be to do a check of the status in the OnClickListener and then determine whether or not the click should do something vs adding and clearing click listeners.

If you use as following, your code can be more effective than you wrote. You should add another feature.

.abc, .xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a.abc, a.xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a {
margin-left:20px;
width: 100px;
height: 100px;
} 

Swap should take place on the Instance Storage (ephemeral) disk and not an EBS device. Swapping will cause a lot of IO and will increase cost on EBS. EBS is also slower than the Instance Store and the Instance Store comes free with certain types of EC2 Instances.

It will usually be mounted to /mnt but if not run

sudo mount /dev/xvda2 /mnt

To then create a swap file on this device do the following for a 4GB swapfile

sudo dd if=/dev/zero of=/mnt/swapfile bs=1M count=4096

Make sure no other user can view the swap file

sudo chown root:root /mnt/swapfile
sudo chmod 600 /mnt/swapfile

Make and Flag as swap

sudo mkswap /mnt/swapfile
sudo swapon /mnt/swapfile

Add/Make sure the following are in your /etc/fstab

/dev/xvda2      /mnt    auto    defaults,nobootwait,comment=cloudconfig 0   2
/mnt/swapfile swap swap defaults 0 0

lastly enable swap

sudo swapon -a

Maybe it is not quite as elegant, but the following might also work. I suspect asynchronously this would not be a good solution.

$p = Start-Process myjob.bat -redirectstandardoutput $logtempfile -redirecterroroutput $logtempfile -wait
add-content $logfile (get-content $logtempfile)

For example, if you want to replace search1 with replace1 and search2 with replace2 then following code will work:

print str_replace(
    array("search1","search2"),
    array("replace1", "replace2"),
    "search1 search2"
);

// Output: replace1 replace2

Instead of creating the PowerPoint presentation in a MemoryStream write it directly to the Response.OutputStream. This way you don't need to be wasting any memory on the sever as the component will be directly streaming the output to the network socket stream. So instead of passing a MemoryStream to the function that is generating this presentation simply pass the Response.OutputStream.

You probably have two options, as SQL Server doesn't support table backups. Both would start with scripting the table creation. Then you can either use the Script Table - INSERT option which will generate a lot of insert statements, or you can use Integration services (DTS with 2000) or similar to export the data as CSV or similar.

With the dplyr package, you can use summarise_all, summarise_at or summarise_if functions to aggregate multiple variables simultaneously. For the example dataset you can do this as follows:

library(dplyr)
# summarising all non-grouping variables
df2 <- df1 %>% group_by(year, month) %>% summarise_all(sum)

# summarising a specific set of non-grouping variables
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(x1, x2), sum)
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(-date), sum)

# summarising a specific set of non-grouping variables using select_helpers
# see ?select_helpers for more options
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(starts_with('x')), sum)
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(matches('.*[0-9]')), sum)

# summarising a specific set of non-grouping variables based on condition (class)
df2 <- df1 %>% group_by(year, month) %>% summarise_if(is.numeric, sum)

The result of the latter two options:

    year month        x1         x2
   <dbl> <dbl>     <dbl>      <dbl>
1   2000     1 -73.58134  -92.78595
2   2000     2 -57.81334 -152.36983
3   2000     3 122.68758  153.55243
4   2000     4 450.24980  285.56374
5   2000     5 678.37867  384.42888
6   2000     6 792.68696  530.28694
7   2000     7 908.58795  452.31222
8   2000     8 710.69928  719.35225
9   2000     9 725.06079  914.93687
10  2000    10 770.60304  863.39337
# ... with 14 more rows

Note: summarise_each is deprecated in favor of summarise_all, summarise_at and summarise_if.

As mentioned in my comment above, you can also use the recast function from the reshape2-package:

library(reshape2)
recast(df1, year + month ~ variable, sum, id.var = c("date", "year", "month"))

which will give you the same result.

NullPointerExceptions are among the easier exceptions to diagnose, frequently. Whenever you get an exception in Java and you see the stack trace ( that's what your second quote-block is called, by the way ), you read from top to bottom. Often, you will see exceptions that start in Java library code or in native implementations methods, for diagnosis you can just skip past those until you see a code file that you wrote.

Then you like at the line indicated and look at each of the objects ( instantiated classes ) on that line -- one of them was not created and you tried to use it. You can start by looking up in your code to see if you called the constructor on that object. If you didn't, then that's your problem, you need to instantiate that object by calling new Classname( arguments ). Another frequent cause of NullPointerExceptions is accidentally declaring an object with local scope when there is an instance variable with the same name.

In your case, the exception occurred in your constructor for Workshop on line 75. <init> means the constructor for a class. If you look on that line in your code, you'll see the line

denimjeansButton.addItemListener(this);

There are fairly clearly two objects on this line: denimjeansButton and this. this is synonymous with the class instance you are currently in and you're in the constructor, so it can't be this. denimjeansButton is your culprit. You never instantiated that object. Either remove the reference to the instance variable denimjeansButton or instantiate it.

Create a UITextView inside of a tableViewController. I used function: textViewDidChange and then checked for return-key-input. then if it detected return-key-input, delete the input of return key and dismiss keyboard.

func textViewDidChange(_ textView: UITextView) {
    tableView.beginUpdates()
    if textView.text.contains("\n"){
        textView.text.remove(at: textView.text.index(before: textView.text.endIndex))
        textView.resignFirstResponder()
    }
    tableView.endUpdates()
}

SELECT (sub)queries return result sets. So you need to use IN, not = in your WHERE clause.

Additionally, as shown in this answer you cannot modify the same table from a subquery within the same query. However, you can either SELECT then DELETE in separate queries, or nest another subquery and alias the inner subquery result (looks rather hacky, though):

DELETE FROM posts WHERE id IN (
    SELECT * FROM (
        SELECT id FROM posts GROUP BY id HAVING ( COUNT(id) > 1 )
    ) AS p
)

Or use joins as suggested by Mchl.

You can use DateTime

import org.joda.time.DateTime

Option 1 : with yyyyMMddHHmmss

DateTime.now().toString("yyyyMMddHHmmss")

Will give 20190205214430

Option 2 : yyyy-dd-M--HH-mm-ss

   DateTime.now().toString("yyyy-dd-M--HH-mm-ss")

will give 2019-05-2--21-43-32

React Router v4

There's a couple of things that I needed to get this working smoothly.

The doc page on auth workflow has quite a lot of what is required.

However I had three issues

1. Where does the props.history come from?
2. How do I pass it through to my component which isn't directly inside the Route component
3. What if I want other props?

I ended up using:

1. option 2 from an answer on 'Programmatically navigate using react router' - i.e. to use <Route render> which gets you props.history which can then be passed down to the children.
2. Use the render={routeProps => <MyComponent {...props} {routeProps} />} to combine other props from this answer on 'react-router - pass props to handler component'

N.B. With the render method you have to pass through the props from the Route component explicitly. You also want to use render and not component for performance reasons (component forces a reload every time).

const App = (props) => (
    <Route 
        path="/home" 
        render={routeProps => <MyComponent {...props} {...routeProps}>}
    />
)

const MyComponent = (props) => (
    /**
     * @link https://reacttraining.com/react-router/web/example/auth-workflow
     * N.B. I use `props.history` instead of `history`
     */
    <button onClick={() => {
        fakeAuth.signout(() => props.history.push('/foo'))
    }}>Sign out</button>
)

One of the confusing things I found is that in quite a few of the React Router v4 docs they use MyComponent = ({ match }) i.e. Object destructuring, which meant initially I didn't realise that Route passes down three props, match, location and history

I think some of the other answers here are assuming that everything is done via JavaScript classes.

Here's an example, plus if you don't need to pass any props through you can just use component

class App extends React.Component {
    render () {
        <Route 
            path="/home" 
            component={MyComponent}
        />
    }
}

class MyComponent extends React.Component {
    render () {
        /**
         * @link https://reacttraining.com/react-router/web/example/auth-workflow
         * N.B. I use `props.history` instead of `history`
         */
        <button onClick={() => {
            this.fakeAuth.signout(() => this.props.history.push('/foo'))
        }}>Sign out</button>
    }
}

printf already crops the trailing newline for you:

$ printf '%s' $(wc -l < log.txt)

Detail:

• printf will print your content in place of the %s string place holder.
• If you do not tell it to print a newline (%s\n), it won't.

You can simplify Joe Kington's code using the axparameter of figure.colorbar() with a list of axes. From the documentation:

ax

None | parent axes object(s) from which space for a new colorbar axes will be stolen. If a list of axes is given they will all be resized to make room for the colorbar axes.

import numpy as np
import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=2, ncols=2)
for ax in axes.flat:
    im = ax.imshow(np.random.random((10,10)), vmin=0, vmax=1)

fig.colorbar(im, ax=axes.ravel().tolist())

plt.show()

The :nth-child(n) selector matches every element that is the nth child, regardless of type, of its parent. Odd and even are keywords that can be used to match child elements whose index is odd or even (the index of the first child is 1).

this is what you want:

<html>
    <head>
        <style>
            li { color: blue }<br>
            li:nth-child(even) { color:red }
            li:nth-child(odd) { color:green}
        </style>
    </head>
    <body>
        <ul>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
        </ul>
    </body>
</html>

You can get all post data into this function :-

$postData = $request->post();

and if you want specific filed then use it :-

$request->post('current-password');

Wait and await - while similar conceptually - are actually completely different.

Wait will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async all the way down"; that is, don't block on async code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.

await will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await expression completes, the remainder of the method is scheduled as a continuation.

You also mentioned a "cooperative block", by which I assume you mean a task that you're Waiting on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait cannot execute the Delay task inline because there's no code for it).

You may find my async / await intro helpful.
