BCL provided Convert.ToString(n, 2) is good, but in case you need an alternate implementation which is few ticks faster than BCL provided one.

Following custom implementation works for all integers(-ve and +ve). Original source taken from https://davidsekar.com/algorithms/csharp-program-to-convert-decimal-to-binary

static string ToBinary(int n)
{
    int j = 0;
    char[] output = new char[32];

    if (n == 0)
        output[j++] = '0';
    else
    {
        int checkBit = 1 << 30;
        bool skipInitialZeros = true;
        // Check the sign bit separately, as 1<<31 will cause
        // +ve integer overflow
        if ((n & int.MinValue) == int.MinValue)
        {
            output[j++] = '1';
            skipInitialZeros = false;
        }

        for (int i = 0; i < 31; i++, checkBit >>= 1)
        {
            if ((n & checkBit) == 0)
            {
                if (skipInitialZeros)
                    continue;
                else
                    output[j++] = '0';
            }
            else
            {
                skipInitialZeros = false;
                output[j++] = '1';
            }
        }
    }

    return new string(output, 0, j);
}

Above code is my implementation. So, I'm eager to hear any feedback :)

In Windows PowerShell version 1 or later to stop a process on port 3000 type:

Stop-Process (,(netstat -ano | findstr :3000).split() | foreach {$[$.length-1]}) -Force

As suggested by @morganpdx here`s a more PowerShell-ish, better version:

Stop-Process -Id (Get-NetTCPConnection -LocalPort 3000).OwningProcess -Force

BE CAREFUL

In some browsers:

flex:1; does not equal flex:1 1 0;

flex:1; = flex:1 1 0n; (where n is a length unit).

• flex-grow: A number specifying how much the item will grow relative to the rest of the flexible items.
• flex-shrink A number specifying how much the item will shrink relative to the rest of the flexible items
• flex-basis The length of the item. Legal values: "auto", "inherit", or a number followed by "%", "px", "em" or any other length unit.

The key point here is that flex-basis requires a length unit.

In Chrome for example flex:1 and flex:1 1 0 produce different results. In most circumstances it may appear that flex:1 1 0; is working but let's examine what really happens:

EXAMPLE

Flex basis is ignored and only flex-grow and flex-shrink are applied.

flex:1 1 0; = flex:1 1; = flex:1;

This may at first glance appear ok however if the applied unit of the container is nested; expect the unexpected!

Try this example in CHROME

.Wrap{_x000D_
  padding:10px;_x000D_
  background: #333;_x000D_
}_x000D_
.Flex110x, .Flex1, .Flex110, .Wrap {_x000D_

}

    <input type="submit" name="test3" value="TEST 3">_x000D_
  </div>_x000D_
</div>

COMPATIBILITY

It should be noted that this fails because some browsers have failed to adhere to the specification.

Browsers that use the full flex specification:

• Firefox - ?
• Edge - ? (I know, I was shocked too.)
• Chrome - x
• Brave - x
• Opera - x
• IE - (lol, it works without length unit but not with one.)

UPDATE 2019

Latest versions of Chrome seem to have finally rectified this issue but other browsers still have not.

Tested and working in Chrome Ver 74.

Here is one simple PHP Script which gets exchange rate between GBP and USD

<?php
$amount = urlencode("1");
$from_GBP0 = urlencode("GBP");
$to_usd= urlencode("USD");
$Dallor = "hl=en&q=$amount$from_GBP0%3D%3F$to_usd";
$US_Rate = file_get_contents("http://google.com/ig/calculator?".$Dallor);
$US_data = explode('"', $US_Rate);
$US_data = explode(' ', $US_data['3']);
$var_USD = $US_data['0'];
echo $to_usd;
echo $var_USD;
echo '<br/>'; 
?>

You can filter all 'invalid' chars with a custom FilterReader class:

public class InvalidXmlCharacterFilter extends FilterReader {

    protected InvalidXmlCharacterFilter(Reader in) {
        super(in);
    }

    @Override
    public int read(char[] cbuf, int off, int len) throws IOException {
        int read = super.read(cbuf, off, len);
        if (read == -1) return read;

        for (int i = off; i < off + read; i++) {
            if (!XMLChar.isValid(cbuf[i])) cbuf[i] = '?';
        }
        return read;
    }
}

And run it like this:

InputStream fileStream = new FileInputStream(xmlFile);
Reader reader = new BufferedReader(new InputStreamReader(fileStream, charset));
InvalidXmlCharacterFilter filter = new InvalidXmlCharacterFilter(reader);
InputSource is = new InputSource(filter);
xmlReader.parse(is);

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()
}

To augment T.J.'s answer, exceeding the min/max values generates an Invalid Date.

let maxDate = new Date(8640000000000000);_x000D_
let minDate = new Date(-8640000000000000);_x000D_
_x000D_
console.log(new Date(maxDate.getTime()).toString());_x000D_
console.log(new Date(maxDate.getTime() - 1).toString());_x000D_
console.log(new Date(maxDate.getTime() + 1).toString()); // Invalid Date_x000D_
_x000D_
console.log(new Date(minDate.getTime()).toString());_x000D_
console.log(new Date(minDate.getTime() + 1).toString());_x000D_
console.log(new Date(minDate.getTime() - 1).toString()); // Invalid Date

To declare a variable as a Decimal, first declare it as a Variant and then convert to Decimal with CDec. The type would be Variant/Decimal in the watch window:

Considering that programming floating point arithmetic is not what one has studied during Maths classes at school, one should always try to avoid common pitfalls by converting to decimal whenever possible.

In the example below, we see that the expression:

0.1 + 0.11 = 0.21

is either True or False, depending on whether the collectibles (0.1,0.11) are declared as Double or as Decimal:

Public Sub TestMe()

    Dim preciseA As Variant: preciseA = CDec(0.1)
    Dim preciseB As Variant: preciseB = CDec(0.11)

    Dim notPreciseA As Double: notPreciseA = 0.1
    Dim notPreciseB As Double: notPreciseB = 0.11

    Debug.Print preciseA + preciseB
    Debug.Print preciseA + preciseB = 0.21 'True

    Debug.Print notPreciseA + notPreciseB
    Debug.Print notPreciseA + notPreciseB = 0.21 'False

End Sub

CSS
select{
  color:red;
 }

HTML
<select id="sel" onclick="document.getElementById('sel').style.color='green';">
 <option>Select Your Option</option>
 <option value="">INDIA</option>
 <option value="">USA</option>
</select>

The above code will change the colour of text on click of the select box.

and if you want every option different colour, give separate class or id to all options.

Also check out include-what-you-use, which solves a similar problem.

    try {
        InputStream connInputStream = connection.getInputStream();
    } catch (IOException e) {
        e.printStackTrace();
    }

    int size = connInputStream.available();

int available () Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream. The next invocation might be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes.

The cleanest way to work with it. Assuming your table is a list of integers called "dbo.tvp_Int" (Customize for your own table type)

Create this extension method...

public static void AddWithValue_Tvp_Int(this SqlParameterCollection paramCollection, string parameterName, List<int> data)
{
   if(paramCollection != null)
   {
       var p = paramCollection.Add(parameterName, SqlDbType.Structured);
       p.TypeName = "dbo.tvp_Int";
       DataTable _dt = new DataTable() {Columns = {"Value"}};
       data.ForEach(value => _dt.Rows.Add(value));
       p.Value = _dt;
   }
}

Now you can add a table valued parameter in one line anywhere simply by doing this:

cmd.Parameters.AddWithValueFor_Tvp_Int("@IDValues", listOfIds);

Demo: http://jsfiddle.net/sunnycpp/u4vjR/2/

Here I have created handle-destroy directive.

ctrl.directive('handleDestroy', function() {
    return function(scope, tElement, attributes) {        
        scope.$on('$destroy', function() {
            alert("In destroy of:" + scope.todo.text);
        });
    };
});

One octet is 8 bits. Content-length is the number of octets that the message body represents.

Go to values> strings inside add string

use "\n" to add new line

then add the string name inside the text view

android:text="@string/category"

You can always simply add an alert() prompt anywhere in a function. Especially useful for knowing if a function was called, if a function completed or where a function fails.

alert('start of function x');
alert('end of function y');
alert('about to call function a');
alert('returned from function b');

You get the idea.

SQL Server 2008 And Up

Just filter a unique index:

CREATE UNIQUE NONCLUSTERED INDEX UQ_Party_SamAccountName
ON dbo.Party(SamAccountName)
WHERE SamAccountName IS NOT NULL;

In Lower Versions, A Materialized View Is Still Not Required

For SQL Server 2005 and earlier, you can do it without a view. I just added a unique constraint like you're asking for to one of my tables. Given that I want uniqueness in column SamAccountName, but I want to allow multiple NULLs, I used a materialized column rather than a materialized view:

ALTER TABLE dbo.Party ADD SamAccountNameUnique
   AS (Coalesce(SamAccountName, Convert(varchar(11), PartyID)))
ALTER TABLE dbo.Party ADD CONSTRAINT UQ_Party_SamAccountName
   UNIQUE (SamAccountNameUnique)

You simply have to put something in the computed column that will be guaranteed unique across the whole table when the actual desired unique column is NULL. In this case, PartyID is an identity column and being numeric will never match any SamAccountName, so it worked for me. You can try your own method—be sure you understand the domain of your data so that there is no possibility of intersection with real data. That could be as simple as prepending a differentiator character like this:

Coalesce('n' + SamAccountName, 'p' + Convert(varchar(11), PartyID))

Even if PartyID became non-numeric someday and could coincide with a SamAccountName, now it won't matter.

Note that the presence of an index including the computed column implicitly causes each expression result to be saved to disk with the other data in the table, which DOES take additional disk space.

Note that if you don't want an index, you can still save CPU by making the expression be precalculated to disk by adding the keyword PERSISTED to the end of the column expression definition.

In SQL Server 2008 and up, definitely use the filtered solution instead if you possibly can!

Controversy

Please note that some database professionals will see this as a case of "surrogate NULLs", which definitely have problems (mostly due to issues around trying to determine when something is a real value or a surrogate value for missing data; there can also be issues with the number of non-NULL surrogate values multiplying like crazy).

However, I believe this case is different. The computed column I'm adding will never be used to determine anything. It has no meaning of itself, and encodes no information that isn't already found separately in other, properly defined columns. It should never be selected or used.

So, my story is that this is not a surrogate NULL, and I'm sticking to it! Since we don't actually want the non-NULL value for any purpose other than to trick the UNIQUE index to ignore NULLs, our use case has none of the problems that arise with normal surrogate NULL creation.

All that said, I have no problem with using an indexed view instead—but it brings some issues with it such as the requirement of using SCHEMABINDING. Have fun adding a new column to your base table (you'll at minimum have to drop the index, and then drop the view or alter the view to not be schema bound). See the full (long) list of requirements for creating an indexed view in SQL Server (2005) (also later versions), (2000).

Update

If your column is numeric, there may be the challenge of ensuring that the unique constraint using Coalesce does not result in collisions. In that case, there are some options. One might be to use a negative number, to put the "surrogate NULLs" only in the negative range, and the "real values" only in the positive range. Alternately, the following pattern could be used. In table Issue (where IssueID is the PRIMARY KEY), there may or may not be a TicketID, but if there is one, it must be unique.

ALTER TABLE dbo.Issue ADD TicketUnique
   AS (CASE WHEN TicketID IS NULL THEN IssueID END);
ALTER TABLE dbo.Issue ADD CONSTRAINT UQ_Issue_Ticket_AllowNull
   UNIQUE (TicketID, TicketUnique);

If IssueID 1 has ticket 123, the UNIQUE constraint will be on values (123, NULL). If IssueID 2 has no ticket, it will be on (NULL, 2). Some thought will show that this constraint cannot be duplicated for any row in the table, and still allows multiple NULLs.

Simple way to compare time is :

$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
     // your code
}

see 15.22.2 of the JLS. For boolean operands, the & operator is boolean, not bitwise. The only difference between && and & for boolean operands is that for && it is short circuited (meaning that the second operand isn't evaluated if the first operand evaluates to false).

So in your case, if b is a primitive, a = a && b, a = a & b, and a &= b all do the same thing.

If you're using jQuery Cookie (https://plugins.jquery.com/cookie/), you can use decimal point or fractions.

As one day is 1, one minute would be 1 / 1440 (there's 1440 minutes in a day).

So 30 minutes is 30 / 1440 = 0.02083333.

Final code:

$.cookie("example", "foo", { expires: 30 / 1440, path: '/' });

I've added path: '/' so that you don't forget that the cookie is set on the current path. If you're on /my-directory/ the cookie is only set for this very directory.

Generally you would use the exit() method with an appropriate exit status.

Zero would mean a successful run. A non-zero status indicates some sort of problem has occurred. This exit code is used by parent processes (e.g. shell scripts) to determine if a process has run successfully.

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

I think

from io import open

should do.

You can just try to download data, and if connection fail you will know that somethings with connection isn't fine.

Basically you can't check if computer is connected to internet. There can be many reasons for failure, like wrong DNS configuration, firewalls, NAT. So even if you make some tests, you can't have guaranteed that you will have connection with your API until you try.

You are comparing a jQuery object (jQuery('input:first')) to strings (the elements of the array).
Change the code in order to compare the input's value (wich is a string) to the array elements:

if (jQuery.inArray(jQuery("input:first").val(), ar) != -1)

The inArray method returns -1 if the element wasn't found in the array, so as your bonus answer to how to determine if an element is not in an array, use this :

if(jQuery.inArray(el,arr) == -1){
    // the element is not in the array
};

The way I fixed similar issue was by adding Month to my SELECT portion

Month DATEADD(day,Created_Date,'1971/12/31') As Month

and than I added WHERE statement

Month DATEADD(day,Created_Date,'1971/12/31') = month(getdate())-1

UPDATE:

onActivityCreated() is deprecated from API Level 28.

onCreate():

The onCreate() method in a Fragment is called after the Activity's onAttachFragment() but before that Fragment's onCreateView().
In this method, you can assign variables, get Intent extras, and anything else that doesn't involve the View hierarchy (i.e. non-graphical initialisations). This is because this method can be called when the Activity's onCreate() is not finished, and so trying to access the View hierarchy here may result in a crash.

onCreateView():

After the onCreate() is called (in the Fragment), the Fragment's onCreateView() is called. You can assign your View variables and do any graphical initialisations. You are expected to return a View from this method, and this is the main UI view, but if your Fragment does not use any layouts or graphics, you can return null (happens by default if you don't override).

onActivityCreated():

As the name states, this is called after the Activity's onCreate() has completed. It is called after onCreateView(), and is mainly used for final initialisations (for example, modifying UI elements). This is deprecated from API level 28.

To sum up...
... they are all called in the Fragment but are called at different times.
The onCreate() is called first, for doing any non-graphical initialisations. Next, you can assign and declare any View variables you want to use in onCreateView(). Afterwards, use onActivityCreated() to do any final initialisations you want to do once everything has completed.

If you want to view the official Android documentation, it can be found here:

• onCreate()
• onCreateView()
• onActivityCreated()_

There are also some slightly different, but less developed questions/answers here on Stack Overflow:

• onCreate() vs onCreateView()
• onCreateView() vs onActivityCreated()

If you manually write out the query with static date values (e.g. '2009-10-29 13:13:07.440') do you get any rows?

So, you are saying that the following two queries produce correct results:

SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat 
    INNER JOIN PubAdvertiser AS pa 
        ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > '2009-10-29 13:13:07.440') AND (pa.AdvertiserID = 12345))

DECLARE @sp_Date DATETIME
SET @sp_Date = '2009-10-29 13:13:07.440'

SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat 
    INNER JOIN PubAdvertiser AS pa 
        ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > @sp_Date) AND (pa.AdvertiserID = 12345))

Which version of Firefox on which platform is your client using?

The are people having the same problem as documented here in the Support Forum for Firefox. I hope you can find a solution there. Good luck!

Update:

Let your client check the settings in Firefox: On "Advanced" - "Encryption" there is a button "View Certificates". Look for "Comodo CA Limited" in the list. I saw that Comodo is the issuer of the certificate of that domain name/server. On two of my machines (FF 3.0.3 on Vista and Mac) the entry is in the list (by default/Mozilla).

2018, without JQuery

I know the question is about JQuery: this answer is just FYI.

document.getElementById('edit').addEventListener(event => {
    event.preventDefault();
    [...document.querySelectorAll('.inputDisabled')].map(e => e.disabled = false);
}); 

Symfony is smart and knows how to make the find() by itself :

public function deleteGuestAction(Guest $guest)
{
    if (!$guest) {
        throw $this->createNotFoundException('No guest found');
    }

    $em = $this->getDoctrine()->getEntityManager();
    $em->remove($guest);
    $em->flush();

    return $this->redirect($this->generateUrl('GuestBundle:Page:viewGuests.html.twig'));
}

To send the id in your controller, use {{ path('your_route', {'id': guest.id}) }}

You need to point to the directory instead. You must not specify the dockerfile.

docker build -t ubuntu-test:latest . does work.

docker build -t ubuntu-test:latest ./Dockerfile does not work.

There is a Firebug-like tool already built into Chrome. Just right click anywhere on a page and choose "Inspect element" from the menu. Chrome has a graphical tool for debugging (like in Firebug), so you can debug JavaScript. It also does CSS inspection well and can even change CSS rendering on the fly.

For more information, see https://developers.google.com/chrome-developer-tools/

To color each cell based on its current integer value, the following should work, if you have a recent version of Excel. (Older versions don't handle rgb as well)

Sub Colourise()
'
' Colourise Macro
'
' Colours all selected cells, based on their current integer rgb value
' For e.g. (it's a bit backward from what you might expect)
' 255 = #ff0000 = red
' 256*255 = #00ff00 = green
' 256*256*255 #0000ff = blue
' 255 + 256*256*255 #ff00ff = magenta
' and so on...
'
' Keyboard Shortcut: Ctrl+Shift+C (or whatever you want to set it to)
'
  For Each cell In Selection
    If WorksheetFunction.IsNumber(cell) Then
      cell.Interior.Color = cell.Value
    End If
  Next cell
End Sub

If instead of a number you have a string then you can split the string into three numbers and combine them using rgb().

I`ve added

initSelection: function (element, callback) {

      callback({ id: 1, text: 'Text' });
}

BUT also

.select2('val', []);

at the end.

This solved my issue.

try to add #include "stdafx.h" before #include "iostream"

i had this problem yesterday. can you folow the local path in windows explorer?

(C:\users\..\AndroidStudioProjects\SharedPreferencesDemoProject\SharedPreferencesDemo\build\apk\) 

i had to manually create the 'apk' directory in '\build', then the problem was fixed

So the solution to the original problem is that you don't need both the "@see" and the "{@link...}" references on the same line. The "@link" tag is self-sufficient and, as noted, you can put it anywhere in the javadoc block. So you can mix the two approaches:

/**
 * some javadoc stuff
 * {@link com.my.package.Class#method()}
 * more stuff
 * @see com.my.package.AnotherClass
 */

The entity   produces a non-breaking space, which is used when you don't want an automatic line break at that position. The regular space has the character code 32, while the non-breaking space has the character code 160.

For example when you display numbers with space as thousands separator: 1 234 567, then you use non-breaking spaces so that the number can't be split on separate lines. If you display currency and there is a space between the amount and the currency: 42 SEK, then you use a non-breaking space so that you don't get the amount on one line and the currency on the next.

If you want to make it fast, you could use a lookup table like in Bit Twiddling Hacks (integer log2 only).

uint32_t v; // find the log base 2 of 32-bit v
int r;      // result goes here

static const int MultiplyDeBruijnBitPosition[32] = 
{
  0, 9, 1, 10, 13, 21, 2, 29, 11, 14, 16, 18, 22, 25, 3, 30,
  8, 12, 20, 28, 15, 17, 24, 7, 19, 27, 23, 6, 26, 5, 4, 31
};

v |= v >> 1; // first round down to one less than a power of 2 
v |= v >> 2;
v |= v >> 4;
v |= v >> 8;
v |= v >> 16;

r = MultiplyDeBruijnBitPosition[(uint32_t)(v * 0x07C4ACDDU) >> 27];

In addition you should take a look at your compilers builtin methods like _BitScanReverse which could be faster because it may entirely computed in hardware.

Take also a look at possible duplicate How to do an integer log2() in C++?

Delete your package-lock.json file and node_modules folder. Then do npm cache clean

npm cache clean --force

do npm install

again and run

It looks like the machine you're trying to run this on has only 256 MB memory.

Maybe the JVM tries to allocate a large, contiguous block of 64 MB memory. The 192 MB that you have free might be fragmented into smaller pieces, so that there is no contiguous block of 64 MB free to allocate.

Try starting your Java program with a smaller heap size, for example:

java -Xms16m ...

For your specific case, the body is for creating a variable, and switching to IEnumerable will force all the operations to be processed on client-side, I propose the following solution.

Obj[] myArray = objects
.Select(o => new
{
    SomeLocalVar = o.someVar, // You can even use any LINQ statement here
    Info = o,
}).Select(o => new Obj()
{
    Var1 = o.SomeLocalVar,
    Var2 = o.Info.var2,
    Var3 = o.SomeLocalVar.SubValue1,
    Var4 = o.SomeLocalVar.SubValue2,
}).ToArray();

Refer to Section 8.3 of this SAML core pdf of oasis SAML specification.

SP and IdP usually communicate each other about a subject. That subject should be identified through a NAME-IDentifier , which should be in some format so that It is easy for the other party to identify it based on the Format.

All these

1.urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified [default]

2.urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress

3.urn:oasis:names:tc:SAML:2.0:nameid-format:persistent

4.urn:oasis:names:tc:SAML:2.0:nameid-format:transient

are format for the Name Identifiers.

The name format for a transient ID in SAML 1 is urn:mace:shibboleth:1.0:nameIdentifier and in SAML 2 is urn:oasis:names:tc:SAML:2.0:nameid-format:transient

Transient is for [section 8.3.8 of SAML Core]

Indicates that the content of the element is an identifier with transient semantics and SHOULD be treated as an opaque and temporary value by the relying party.

Unspecified can be used and it purely depends on the entities implementation on their own wish.

C# Test Coverage Tool has very low overhead, handles huge systems of files, intuitive GUI showing coverage on specific files, and generated report with coverage breakdown at method, class, and package levels.

If you've tried ssh-add and you're still prompted to enter your passphrase then try using ssh-add -K. This adds your passphrase to your keychain.

Update: if you're using macOS Sierra then you likely need to do another step as the above might no longer work. Add the following to your ~/.ssh/config:

Host *
  UseKeychain yes

I had similar situation and here is my approach which is somewhat different:

 HADOOP_USER_NAME=hdfs hdfs dfs -put /root/MyHadoop/file1.txt /

What you actually do is you read local file in accordance to your local permissions but when placing file on HDFS you are authenticated like user hdfs. You can do this with other ID (beware of real auth schemes configuration but this is usually not a case).

Advantages:

1. Permissions are kept on HDFS.
2. You don't need sudo.
3. You don't need actually appropriate local user 'hdfs' at all.
4. You don't need to copy anything or change permissions because of previous points.

An easy way to install Java 7 on a Mac is by using Homebrew, thanks to the Homebrew Cask plugin (which is now installed by default).

Run this command to install Java 7:

brew cask install caskroom/versions/java7

you can include @ in a 'scriptBlock' like this:

@(
  echo don't echoed
  hostname
)
echo echoed

and especially do not do that :)

for %%a in ("@") do %%~aecho %%~a

this is how I implement it .

Mike Nereson has this to say on his blog at:

http://blog.codehangover.com/load-multiple-contexts-into-spring/

There are a couple of ways to do this.

1. web.xml contextConfigLocation

Your first option is to load them all into your Web application context via the ContextConfigLocation element. You’re already going to have your primary applicationContext here, assuming you’re writing a web application. All you need to do is put some white space between the declaration of the next context.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value>
          applicationContext1.xml
          applicationContext2.xml
      </param-value>
  </context-param>

  <listener>
      <listener-class>
          org.springframework.web.context.ContextLoaderListener
      </listener-class>
  </listener>

The above uses carriage returns. Alternatively, yo could just put in a space.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value> applicationContext1.xml applicationContext2.xml </param-value>
  </context-param>

  <listener>
      <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class>
  </listener>

2. applicationContext.xml import resource

Your other option is to just add your primary applicationContext.xml to the web.xml and then use import statements in that primary context.

In applicationContext.xml you might have…

  <!-- hibernate configuration and mappings -->
  <import resource="applicationContext-hibernate.xml"/>

  <!-- ldap -->
  <import resource="applicationContext-ldap.xml"/>

  <!-- aspects -->
  <import resource="applicationContext-aspects.xml"/>

Which strategy should you use?

1. I always prefer to load up via web.xml.

Because , this allows me to keep all contexts isolated from each other. With tests, we can load just the contexts that we need to run those tests. This makes development more modular too as components stay loosely coupled, so that in the future I can extract a package or vertical layer and move it to its own module.

2. If you are loading contexts into a non-web application, I would use the import resource.

Available in most UNIX system, ksh is standard-comliant, clearly designed, well-rounded. I think books,helps in ksh is enough and clear, especially the O'Reilly book. Bash is a mass. I keep it as root login shell for Linux at home only.

For interactive use, I prefer zsh on Linux/UNIX. I run scripts in zsh, but I'll test most of my scripts, functions in AIX ksh though.

The problem is that --exclude="*" says to exclude (for example) the 1260000000/ directory, so rsync never examines the contents of that directory, so never notices that the directory contains files that would have been matched by your --include.

I think the closest thing to what you want is this:

rsync -nrv --include="*/" --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/

(which will include all directories, and all files matching file_11*.jpg, but no other files), or maybe this:

rsync -nrv --include="/[0-9][0-9][0-9]0000000/" --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/

(same concept, but much pickier about the directories it will include).

There is an interesting discussion here: http://social.msdn.microsoft.com/Forums/en-US/vcgeneral/thread/307d658a-f677-40f2-bdef-e6352b0bfe9e/ My understanding of this thread is that freeing small allocations are not reflected in Private Bytes or Working Set.

Long story short:

if I call

p=malloc(1000);
free(p);

then the Private Bytes reflect only the allocation, not the deallocation.

if I call

p=malloc(>512k);
free(p);

then the Private Bytes correctly reflect the allocation and the deallocation.

start all daemons and run the command as "hadoop namenode -recover -force" stop the daemons and start again.. wait some time to recover data.

protected void TestSubmit_ServerClick(object sender, EventArgs e)
{
    using (StreamWriter w = new StreamWriter(Server.MapPath("~/data.txt"), true))
    {
        w.WriteLine(TextBox1.Text); // Write the text
    }
}

As far as I understand it, the HTML5 input type="number always returns input.value as a string.

Apparently, input.valueAsNumber returns the current value as a floating point number. You could use this to return a value you want.

See http://diveintohtml5.info/forms.html#type-number

You can put the Link component inside the Router componet. Something like this:

 <Router>
        <Route path='/complete-profiles' component={Profiles} />
        <Link to='/complete-profiles'>
          <div>Completed Profiles</div>
        </Link>
      </Router>

It seems that with ASP.NET Core 2, you can again inherit AuthorizeAttribute, you just need to also implement IAuthorizationFilter (or IAsyncAuthorizationFilter):

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class CustomAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    private readonly string _someFilterParameter;

    public CustomAuthorizeAttribute(string someFilterParameter)
    {
        _someFilterParameter = someFilterParameter;
    }

    public void OnAuthorization(AuthorizationFilterContext context)
    {
        var user = context.HttpContext.User;

        if (!user.Identity.IsAuthenticated)
        {
            // it isn't needed to set unauthorized result 
            // as the base class already requires the user to be authenticated
            // this also makes redirect to a login page work properly
            // context.Result = new UnauthorizedResult();
            return;
        }

        // you can also use registered services
        var someService = context.HttpContext.RequestServices.GetService<ISomeService>();

        var isAuthorized = someService.IsUserAuthorized(user.Identity.Name, _someFilterParameter);
        if (!isAuthorized)
        {
            context.Result = new StatusCodeResult((int)System.Net.HttpStatusCode.Forbidden);
            return;
        }
    }
}

Pfft! Microseconds! Never solve a problem in microseconds that can be solved in nanoseconds.

Note that the accepted answer:

• iterates over the whole data, regardless of whether a nan is found
• creates a temporary array of size N, which is redundant.

A better solution is to return True immediately when NAN is found:

import numba
import numpy as np

NAN = float("nan")

@numba.njit(nogil=True)
def _any_nans(a):
    for x in a:
        if np.isnan(x): return True
    return False

@numba.jit
def any_nans(a):
    if not a.dtype.kind=='f': return False
    return _any_nans(a.flat)

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 573us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 774ns  (!nanoseconds)

and works for n-dimensions:

array1M_nd = array1M.reshape((len(array1M)/2, 2))
assert any_nans(array1M_nd)==True
%timeit any_nans(array1M_nd)  # 774ns

Compare this to the numpy native solution:

def any_nans(a):
    if not a.dtype.kind=='f': return False
    return np.isnan(a).any()

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 456us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 470us

%timeit np.isnan(array1M).any()  # 532us

The early-exit method is 3 orders or magnitude speedup (in some cases). Not too shabby for a simple annotation.

Try something like:

$("#photo").load(function() {
    alert("Hello from Image");
});

Try this

XElement root = XDocument.Load(fStream).Root;

anytree

I recommend https://pypi.python.org/pypi/anytree

Example

from anytree import Node, RenderTree

udo = Node("Udo")
marc = Node("Marc", parent=udo)
lian = Node("Lian", parent=marc)
dan = Node("Dan", parent=udo)
jet = Node("Jet", parent=dan)
jan = Node("Jan", parent=dan)
joe = Node("Joe", parent=dan)

print(udo)
Node('/Udo')
print(joe)
Node('/Udo/Dan/Joe')

for pre, fill, node in RenderTree(udo):
    print("%s%s" % (pre, node.name))
Udo
+-- Marc
¦   +-- Lian
+-- Dan
    +-- Jet
    +-- Jan
    +-- Joe

print(dan.children)
(Node('/Udo/Dan/Jet'), Node('/Udo/Dan/Jan'), Node('/Udo/Dan/Joe'))

Features

anytree has also a powerful API with:

• simple tree creation
• simple tree modification
• pre-order tree iteration
• post-order tree iteration
• resolve relative and absolute node paths
• walking from one node to an other.
• tree rendering (see example above)
• node attach/detach hookups

If you want to apply an extra small class in Bootstrap 4,you need to use col-. important thing to know is that col-xs- is dropped in Bootstrap4

If table1 is large and you don't want to lock it for the duration of the copy process, you can do a dump-and-load instead:

CREATE TABLE table2 LIKE table1;

SELECT * INTO OUTFILE '/tmp/table1.txt' FROM table1;
LOAD DATA INFILE '/tmp/table1.txt' INTO TABLE table2;

1. Configure PHP build to produce xml junit report

   <phpunit bootstrap="tests/bootstrap.php" colors="true" >
      <logging>
          <log type="junit" target="build/junit.xml" 
              logIncompleteSkipped="false" title="Test Results"/>
      </logging>
   
      ....
   
    </phpunit>
   

2. Finish build script with status 0

   ...
   exit 0;
   

3. Add post-build action Publish JUnit test result report for Test report XMLs. This plugin will change Stable build to Unstable when test are failing.

   **/build/junit.xml
   

4. Add Jenkins Text Finder plugin with console output scanning and unchecked options. This plugin fail whole build on fatal error.

   PHP Fatal error:
   

Explanation of command that i am going to write:-

. means any character, digit can come in place of .

* means zero or more occurrences of thing written just previous to it.

| means 'or'.

So,

james.*jack

would search james , then any number of character until jack comes.

Since you want either jack.*james or james.*jack

Hence Command:

jack.*james|james.*jack

While jm-'s answer is the best way to handle this case, for future reference it is possible to access child scopes using a scope's $$childHead, $$childTail, $$nextSibling and $$prevSibling members. These aren't documented so they might change without notice, but they're there if you really need to traverse scopes.

// get $$childHead first and then iterate that scope's $$nextSiblings
for(var cs = scope.$$childHead; cs; cs = cs.$$nextSibling) {
    // cs is child scope
}

Fiddle

With the standard library

Use the subprocess module (Python 3):

import subprocess
subprocess.run(['ls', '-l'])

It is the recommended standard way. However, more complicated tasks (pipes, output, input, etc.) can be tedious to construct and write.

Note on Python version: If you are still using Python 2, subprocess.call works in a similar way.

ProTip: shlex.split can help you to parse the command for run, call, and other subprocess functions in case you don't want (or you can't!) provide them in form of lists:

import shlex
import subprocess
subprocess.run(shlex.split('ls -l'))

With external dependencies

If you do not mind external dependencies, use plumbum:

from plumbum.cmd import ifconfig
print(ifconfig['wlan0']())

It is the best subprocess wrapper. It's cross-platform, i.e. it works on both Windows and Unix-like systems. Install by pip install plumbum.

Another popular library is sh:

from sh import ifconfig

However, sh dropped Windows support, so it's not as awesome as it used to be. Install by pip install sh.

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

You cannot prevent people from copying text from your page. If you are trying to satisfy a "requirement" this may work for you:

<body oncopy="return false" oncut="return false" onpaste="return false">

How to disable Ctrl C/V using javascript for both internet explorer and firefox browsers

A more advanced aproach:

How to detect Ctrl+V, Ctrl+C using JavaScript?

Edit: I just want to emphasise that disabling copy/paste is annoying, won't prevent copying and is 99% likely a bad idea.

I had trouble getting this to work and added another solution for anyone wanting/ needing to use FromCollection.

Instead of:

@Html.CheckBoxFor(model => true, item.TemplateId) 

Format html helper like so:

@Html.CheckBoxFor(model => model.SomeProperty, new { @class = "form-control", Name = "SomeProperty"})

Then in the viewmodel/model wherever your logic is:

public void Save(FormCollection frm)
{   
    // to do instantiate object.

    instantiatedItem.SomeProperty = (frm["SomeProperty"] ?? "").Equals("true", StringComparison.CurrentCultureIgnoreCase);

    // to do and save changes in database.
}

Passing data from PHP is easy, you can generate JavaScript with it. The other way is a bit harder - you have to invoke the PHP script by a Javascript request.

An example (using traditional event registration model for simplicity):

<!-- headers etc. omitted -->
<script>
function callPHP(params) {
    var httpc = new XMLHttpRequest(); // simplified for clarity
    var url = "get_data.php";
    httpc.open("POST", url, true); // sending as POST

    httpc.onreadystatechange = function() { //Call a function when the state changes.
        if(httpc.readyState == 4 && httpc.status == 200) { // complete and no errors
            alert(httpc.responseText); // some processing here, or whatever you want to do with the response
        }
    };
    httpc.send(params);
}
</script>
<a href="#" onclick="callPHP('lorem=ipsum&foo=bar')">call PHP script</a>
<!-- rest of document omitted -->

Whatever get_data.php produces, that will appear in httpc.responseText. Error handling, event registration and cross-browser XMLHttpRequest compatibility are left as simple exercises to the reader ;)

Try this code. You can use $.get instead of $.ajax

$( "input.suggest-user" ).autocomplete({
    source: function( request, response ) {
        $.ajax({
            dataType: "json",
            type : 'Get',
            url: 'yourURL',
            success: function(data) {
                $('input.suggest-user').removeClass('ui-autocomplete-loading');  
                // hide loading image

                response( $.map( data, function(item) {
                    // your operation on data
                }));
            },
            error: function(data) {
                $('input.suggest-user').removeClass('ui-autocomplete-loading');  
            }
        });
    },
    minLength: 3,
    open: function() {},
    close: function() {},
    focus: function(event,ui) {},
    select: function(event, ui) {}
});

It's possible to "natively" select by value:

dropdownlist.select(1);

I think you can use the Application class for many things, but they are all tied to your need to do some stuff BEFORE any of your Activities or Services are started. For instance, in my application I use custom fonts. Instead of calling

Typeface.createFromAsset()

from every Activity to get references for my fonts from the Assets folder (this is bad because it will result in memory leak as you are keeping a reference to assets every time you call that method), I do this from the onCreate() method in my Application class:

private App appInstance;
Typeface quickSandRegular;
...
public void onCreate() {
    super.onCreate();

    appInstance = this;
    quicksandRegular = Typeface.createFromAsset(getApplicationContext().getAssets(),
                       "fonts/Quicksand-Regular.otf");
   ...
   }

Now, I also have a method defined like this:

public static App getAppInstance() {
    return appInstance;
}

and this:

public Typeface getQuickSandRegular() {
    return quicksandRegular;
}

So, from anywhere in my application, all I have to do is:

App.getAppInstance().getQuickSandRegular()

Another use for the Application class for me is to check if the device is connected to the Internet BEFORE activities and services that require a connection actually start and take necessary action.

This workaround also works with 15.04 (64bit). Since there isn't (yet?) lib32bz2-1.0 for vivid:

http://packages.ubuntu.com/search?keywords=lib32bz2-1.0

I installed the one from Utopic.

import os
os.listdir("path") # returns list

To add .pch file-

1) Add new .pch file to your project->New file->other->PCH file

2) Goto your project's build setting.

3) Search "prefix header". You can find that under Apple LLVM.

4) Paste this in the field $(SRCROOT)/yourPrefixHeaderFileName.pch

5) Clean and build the project. That's it!!!

To inactivate the non-desktop styles you just have to change 4 lines of code in the variables.less file. Set the screen width breakpoints in the variables.less file like this:

// Media queries breakpoints
// --------------------------------------------------

// Extra small screen / phone
// Note: Deprecated @screen-xs and @screen-phone as of v3.0.1
@screen-xs:                  1px;
@screen-xs-min:              @screen-xs;
@screen-phone:               @screen-xs-min;

// Small screen / tablet
// Note: Deprecated @screen-sm and @screen-tablet as of v3.0.1
@screen-sm:                  2px;
@screen-sm-min:              @screen-sm;
@screen-tablet:              @screen-sm-min;

// Medium screen / desktop
// Note: Deprecated @screen-md and @screen-desktop as of v3.0.1
@screen-md:                  3px;
@screen-md-min:              @screen-md;
@screen-desktop:             @screen-md-min;

// Large screen / wide desktop
// Note: Deprecated @screen-lg and @screen-lg-desktop as of v3.0.1
@screen-lg:                  9999px;
@screen-lg-min:              @screen-lg;
@screen-lg-desktop:          @screen-lg-min;

This sets the min-width on the desktop style media query lower so that it applies to all screen widths. Thanks to 2calledchaos for the improvement! Some base styles are defined in the mobile styles, so we need to be sure to include them.

Edit: chris notes that you can set these variables in the online less compiler on the bootstrap site

There are some kind of misunderstanding about lazy collections in JPA-Hibernate. First of all let's clear that why trying to read a lazy collection throws exceptions and not just simply returns NULL for converting or further use cases?.

That's because Null fields in Databases especially in joined columns have meaning and not simply not-presented state, like programming languages. when you're trying to interpret a lazy collection to Null value it means (on Datastore-side) there is no relations between these entities and it's not true. so throwing exception is some kind of best-practice and you have to deal with that not the Hibernate.

So as mentioned above I recommend to :

1. Detach the desired object before modifying it or using stateless session for querying
2. Manipulate lazy fields to desired values (zero,null,etc.)

also as described in other answers there are plenty of approaches(eager fetch, joining etc.) or libraries and methods for doing that, but you have to setting up your view of what's happening before dealing with the problem and solving it.

If you're using AD you can use serverless binding to locate a domain controller for the default domain, then use LDAP://rootDSE to get information about the directory server, as described in the linked article.

You can also use := construct to assign and decide on action in one step. Consider following example:

# Example of setting default server and reporting it's status

server=$1
if [[ ${server:=localhost} =~ [a-z] ]]      # 'localhost' assigned here to $server
then    echo "server is localhost"          # echo is triggered since letters were found in $server
else
        echo "server was set" # numbers were passed
fi

If $1 is not empty, localhost will be assigned to server in the if condition field, trigger match and report match result. In this way you can assign on the fly and trigger appropriate action.

You could use:

import os
path = 'the path you want'
os.environ['PATH'] += ':'+path

request.getAttribute("servletName") method will return Object that you need to cast to ArrayList

ArrayList<Category> list =new ArrayList<Category>();
//storing passed value from jsp
list = (ArrayList<Category>)request.getAttribute("servletName");

Very late, but it may help others:

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

I had the issue the imports for the routing module must come after the child module, this might not be directly related to this post but it would have helped me if I read this:

https://angular.io/guide/router#module-import-order-matters

imports: [
  BrowserModule,
  FormsModule,
  ChildModule,
  AppRoutingModule
],

With HTML5, you can do this natively with: <input name="first_name" placeholder="First Name">

This is not supported with all browsers though (IE)

This may work:

<input type="first_name" value="First Name" onfocus="this.value==this.defaultValue?this.value='':null">

Otherwise, if you are using jQuery, you can use .focus and .css to change the color.

I might be late to the party, but there is a cool website where you can search for the packages and it will list the necessary command to install the stuff. BrewInstall is the website.

However you can install wget with the following command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install wget

Hope this helps :)

When you set null=true it will set null in your database if the field is not filled. If you set blank='true it will not set any value to the field.

Whenever I do a merge, I get into the branch I want to merge into (e.g. "git checkout branch-i-am-working-in") and then do the following:

git merge origin/branch-i-want-to-merge-from

select 
  id,
  case 
    when report_type = 'P' 
    then amount 
    when report_type = 'N' 
    then -amount 
    else null 
  end
from table

This is what helped me:

sudo apachectl stop

This command killed Apache server that was pre-installed on MAC OS X.

SELECT firstName, Lastname, MAX(id) as max WHERE YOUR_CONDITIONS_HERE HAVING id=max(id) 

Error messages usually mean precisely what they say. So they must be read very carefully. When you do that, you'll see that this one is not actually complaining, as you seem to have assumed, about what sort of object your list contains, but rather about what sort of object it is. It's not saying it wants your list to contain integers (plural)—instead, it seems to want your list to be an integer (singular) rather than a list of anything. And since you can't convert a list into a single integer (at least, not in a way that is meaningful in this context) you shouldn't be trying.

So the question is: why does the interpreter seem to want to interpret your list as an integer? The answer is that you are passing your list as the input argument to range, which expects an integer. Don't do that. Say for i in myList instead.

Well you can have

class MyClass
{
    public:
        static vector<char> a;

        static class _init
        {
          public:
            _init() { for(char i='a'; i<='z'; i++) a.push_back(i); }
        } _initializer;
};

Don't forget (in the .cpp) this:

vector<char> MyClass::a;
MyClass::_init MyClass::_initializer;

The program will still link without the second line, but the initializer will not be executed.

This addresses the different question, how to get images in gist (as opposed to github) markdown in the first place ?

1. Make a gist, say Mygist.md (and optionally more files)
2. Go to the "Write Comment" box at the end
3. Click "Attach files ... by selecting them"; select your local image file
4. GitHub echos a long long string where it put the image, e.g. 
5. Cut-paste that by hand into your Mygist.md.

But: GitHub people may change this behavior tomorrow, without documenting it.

If your project's source code has import statements that reference classes that are in widget.jar, you should add the jar to your projects Compile-time Libraries. (The jar widget.jar will automatically be added to your project's Run-time Libraries). That corresponds to (1).

If your source code has imports for classes in some other jar and the source code for those classes has import statements that reference classes in widget.jar, you should add widget.jar to the Run-time libraries list. That corresponds to (2).

You can add the jars directly to the Libraries list in the project properties. You can also create a Library that contains the jar file and then include that Library in the Compile-time or Run-time Libraries list.

If you create a NetBeans Library for widget.jar, you can also associate source code for the jar's content and Javadoc for the APIs defined in widget.jar. This additional information about widget.jar will be used by NetBeans as you debug code. It will also be used to provide addition information when you use code completion in the editor.

You should avoid using Tools >> Java Platform to add a jar to a project. That dialog allows you to modify the classpath that is used to compile and run all projects that use the Java Platform that you create. That may be useful at times but hides your project's dependency on widget.jar almost completely.

It can be added by using:

$psql -d databaseName -c "CREATE EXTENSION dblink"

        DateTimeFormatter.ofPattern( "M/d/uuuu" )   // Specify a formatting pattern by which to parse the input string.
    )                                               // Returns a `LocalDate` object.

YearMonth

The YearMonth class makes this easy. The atEndOfMonth method returns a LocalDate. Leap year in February is accounted for.

First define a formatting pattern to match your string input.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "M/d/uuuu" ) ;

Use that formatter to get a LocalDate from the string input.

String s = "1/13/2012" ;
LocalDate ld = LocalDate.parse( "1/13/2012" , f ) ;

Then extract a YearMonth object.

YearMonth ym = YearMonth.from( ld ) ;

Ask that YearMonth to determine the last day of its month in that year, accounting for Leap Year in February.

LocalDate endOfMonth = ym.atEndOfMonth() ;

Generate text representing that date, in standard ISO 8601 format.

String output = endOfMonth.toString() ;  

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

using flex

 <View style={{ flexDirection: 'row',}}>
                  <Text style={{fontSize: 12, lineHeight: 30, color:'#9394B3' }}>left</Text>
                  <Text style={{ flex:1, fontSize: 16, lineHeight: 30, color:'#1D2359', textAlign:'right' }}>right</Text>
               </View>

If you highlight the method Assert.assertEquals(val1, val2) and hit Ctrl + Shift + M (Add Import), it will add it as a static import, at least in Eclipse 3.4.

new Handler().postDelayed(new Runnable() {
    public void run() {
        // do something...              
    }
}, 100);

I had the same problem. I'm very new to iphone development and it was my first time trying to load my program onto my iphone. The message is correct, you need to create a certificate in the keychain. The best walkthrough is here:

http://developer.apple.com/ios/manage/overview/index.action

You of course need to have a developer account (need to have paid the $100 yearly fee).

I hope this helps.

If you want a straight redirect of all output to a file, try using *>>:

# You'll receive standard output for the first command, and an error from the second command.
mkdir c:\temp -force *>> c:\my.log ;
mkdir c:\temp *>> c:\my.log ;

Since this is a straight redirect to file, it won't output to the console (often helpful). If you desire the console output, combined all output with *&>1, and then pipe with Tee-Object:

mkdir c:\temp -force *>&1 | Tee-Object -Append -FilePath c:\my.log ;
mkdir c:\temp *>&1 | Tee-Object -Append -FilePath c:\my.log ;

# Shorter aliased version
mkdir c:\temp *>&1 | tee -Append c:\my.log ;

I believe these techniques are supported in PowerShell 3.0 or later; I'm testing on PowerShell 5.0.

Configurations above didn't work for me. I tried a lot of combinations of keys, this one work fine:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>mydomain.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>

It's probably because you are directly or indirectly through a library call accessing a NULL pointer. In this particular case, it looks like you've jumped to a NULL address, which is a b bit hairier.

In my experience, the easiest way to track these down are to run it with a debugger, and dump a stack trace.

Alternatively, you can do it "by hand" and add lots of logging until you can track down exactly which function (and possibly LOC) this violation occurred in.

Take a look at Stack Tracer, which might help you improve your debugging.

If you want to call the "inner" function with the "outer" function, you can do this:

function outer() { 
     function inner() {
          alert("hi");
     }
     return { inner };
}

And on "onclick" event you call the function like this:

<input type="button" onclick="outer().inner();" value="ACTION">?

I just benchmarked these two approaches on data frame with 663,552 rows using the following code:

system.time(
  resultsByLevel$subject <- sapply(resultsByLevel$variable, function(x) {
    s <- strsplit(x, ".", fixed=TRUE)[[1]]
    s[length(s)]
  })
  )

 user  system elapsed 
  3.722   0.000   3.594 

and

system.time(
  resultsByLevel$subject <- sapply(resultsByLevel$variable, function(x) {
    s <- strsplit(x, ".", fixed=TRUE)[[1]]
    tail(s, n=1)
  })
  )

   user  system elapsed 
 28.174   0.000  27.662 

So, assuming you're working with vectors, accessing the length position is significantly faster.

My kotlin entension function for this purpose

fun Context.canPerformIntent(intent: Intent): Boolean {
        val mgr = this.packageManager
        val list = mgr.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
        return list.size > 0
    }

And in your activity

val uri = if (canPerformIntent(Intent(Intent.ACTION_VIEW, Uri.parse("market://")))) {
            Uri.parse("market://details?id=" + appPackageName)
        } else {
            Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)
        }
        startActivity(Intent(Intent.ACTION_VIEW, uri))

You can use like this:

public static String executeHttpPost1(String url,
            HashMap<String, String> postParameters) throws UnsupportedEncodingException {
        // TODO Auto-generated method stub

        HttpClient client = getNewHttpClient();

        try{
        request = new HttpPost(url);

        }
        catch(Exception e){
            e.printStackTrace();
        }


        if(postParameters!=null && postParameters.isEmpty()==false){

            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(postParameters.size());
            String k, v;
            Iterator<String> itKeys = postParameters.keySet().iterator();
            while (itKeys.hasNext()) 
            {
                k = itKeys.next();
                v = postParameters.get(k);
                nameValuePairs.add(new BasicNameValuePair(k, v));
            }     

            UrlEncodedFormEntity urlEntity  = new  UrlEncodedFormEntity(nameValuePairs);
            request.setEntity(urlEntity);

        }
        try {


            Response = client.execute(request,localContext);
            HttpEntity entity = Response.getEntity();
            int statusCode = Response.getStatusLine().getStatusCode();
            Log.i(TAG, ""+statusCode);


            Log.i(TAG, "------------------------------------------------");

Functional solution with sub-directories:

from fnmatch import filter
from functools import partial
from itertools import chain
from os import path, walk

print(*chain(*(map(partial(path.join, root), filter(filenames, "*.txt")) for root, _, filenames in walk("mydir"))))

There is also EXISTS:

SELECT count(*) AS post_ct
FROM   posts p
WHERE  EXISTS (SELECT FROM votes v WHERE v.post_id = p.id);

In Postgres and with multiple entries on the n-side like you probably have, it's generally faster than count(DISTINCT post_id):

SELECT count(DISTINCT p.id) AS post_ct
FROM   posts p
JOIN   votes v ON v.post_id = p.id;

The more rows per post there are in votes, the bigger the difference in performance. Test with EXPLAIN ANALYZE.

count(DISTINCT post_id) has to read all rows, sort or hash them, and then only consider the first per identical set. EXISTS will only scan votes (or, preferably, an index on post_id) until the first match is found.

If every post_id in votes is guaranteed to be present in the table posts (referential integrity enforced with a foreign key constraint), this short form is equivalent to the longer form:

SELECT count(DISTINCT post_id) AS post_ct
FROM   votes;

May actually be faster than the EXISTS query with no or few entries per post.

The query you had works in simpler form, too:

SELECT count(*) AS post_ct
FROM  (
    SELECT FROM posts 
    JOIN   votes ON votes.post_id = posts.id 
    GROUP  BY posts.id
    ) sub;

Benchmark

To verify my claims I ran a benchmark on my test server with limited resources. All in a separate schema:

Test setup

Fake a typical post / vote situation:

CREATE SCHEMA y;
SET search_path = y;

CREATE TABLE posts (
  id   int PRIMARY KEY
, post text
);

INSERT INTO posts
SELECT g, repeat(chr(g%100 + 32), (random()* 500)::int)  -- random text
FROM   generate_series(1,10000) g;

DELETE FROM posts WHERE random() > 0.9;  -- create ~ 10 % dead tuples

CREATE TABLE votes (
  vote_id serial PRIMARY KEY
, post_id int REFERENCES posts(id)
, up_down bool
);

INSERT INTO votes (post_id, up_down)
SELECT g.* 
FROM  (
   SELECT ((random()* 21)^3)::int + 1111 AS post_id  -- uneven distribution
        , random()::int::bool AS up_down
   FROM   generate_series(1,70000)
   ) g
JOIN   posts p ON p.id = g.post_id;

All of the following queries returned the same result (8093 of 9107 posts had votes).
I ran 4 tests with EXPLAIN ANALYZE ant took the best of five on Postgres 9.1.4 with each of the three queries and appended the resulting total runtimes.

1. As is.

2. After ..

   ANALYZE posts;
   ANALYZE votes;
   

3. After ..

   CREATE INDEX foo on votes(post_id);
   

4. After ..

   VACUUM FULL ANALYZE posts;
   CLUSTER votes using foo;
   

count(*) ... WHERE EXISTS

1. 253 ms
2. 220 ms
3. 85 ms -- winner (seq scan on posts, index scan on votes, nested loop)
4. 85 ms

count(DISTINCT x) - long form with join

1. 354 ms
2. 358 ms
3. 373 ms -- (index scan on posts, index scan on votes, merge join)
4. 330 ms

count(DISTINCT x) - short form without join

1. 164 ms
2. 164 ms
3. 164 ms -- (always seq scan)
4. 142 ms

Best time for original query in question:

• 353 ms

For simplified version:

• 348 ms

@wildplasser's query with a CTE uses the same plan as the long form (index scan on posts, index scan on votes, merge join) plus a little overhead for the CTE. Best time:

• 366 ms

Index-only scans in the upcoming PostgreSQL 9.2 can improve the result for each of these queries, most of all for EXISTS.

Related, more detailed benchmark for Postgres 9.5 (actually retrieving distinct rows, not just counting):

• Select first row in each GROUP BY group?

yum install php-mcrypt.x86_64

worked for me instead of

yum install php-mcrypt

NOTE: This one is just an alternative for the previous provided .NET framework 3.5 and above

You can send it as raw xml

<test>or like this</test>

If you declare the paramater2 as XElement data type

Problem solved! I'm using Ctrl + Alt + E to open Exception Window, and I checked all throw checkbox. So the debuger can stop at the exactly the error code.

foreach($array as $item=>$values){
     echo $values->filepath;
    }

Wrap the content in a <pre> (pre-formatted text) tag

<pre>hello ,
my name is x.</pre>

The asterisk (*) means "zero or more of the previous item".

If you want to match any single character use

sed -i 's/string-./string-0/g' file.txt

If you want to match any string (i.e. any single character zero or more times) use

sed -i 's/string-.*/string-0/g' file.txt

You have multiple oddities happening. The first has been edited in your post, but it had to do with the order that the methods were being called.

.format returns a string. String does not have a subtract method.

The second issue is that you are subtracting the day, but not actually saving that as a variable.

Your code, then, should look like:

var startdate = moment();
startdate = startdate.subtract(1, "days");
startdate = startdate.format("DD-MM-YYYY");

However, you can chain this together; this would look like:

var startdate = moment().subtract(1, "days").format("DD-MM-YYYY");

The difference is that we're setting startdate to the changes that you're doing on startdate, because moment is destructive.

#php -i | grep php.ini also will work too!

Sometimes the problem is in the composer memory limit. In my case, I tried increasing the php memory limit but still got the error. You can use COMPOSER_MEMORY_LIMIT=-1 to get around that. Use it as a prefix:

COMPOSER_MEMORY_LIMIT=-1 composer require the/library

You have to prefix it again in the future.

Hope this helps.

awk -F " " '($1=="A1") {print $NF}' FILE | tail -n 1

Use awk with field separator -F set to a space " ".

Use the pattern $1=="A1" and action {print $NF}, this will print the last field in every record where the first field is "A1". Pipe the result into tail and use the -n 1 option to only show the last line.

From the command line it would be just:

svn update

(in the directory you've got a copy of a SVN project).

Without your seeing your data (you can use the output of dput(head(survey)) to show us) this is a shot in the dark:

survey <- data.frame(date=c("2012/07/26","2012/07/25"),tx_start=c("2012/01/01","2012/01/01"))

survey$date_diff <- as.Date(as.character(survey$date), format="%Y/%m/%d")-
                  as.Date(as.character(survey$tx_start), format="%Y/%m/%d")
survey
       date   tx_start date_diff
1 2012/07/26 2012/01/01  207 days
2 2012/07/25 2012/01/01  206 days

There could be a few things happening here. Start by first figuring out your library location:

Sys.getenv("R_LIBS_USER")

or

.libPaths()

We already know yours from the info you gave: C:\Program Files\R\R-3.0.1\library

I believe you have a file in there called: 00LOCK. From ?install.packages:

Note that it is possible for the package installation to fail so badly that the lock directory is not removed: this inhibits any further installs to the library directory (or for --pkglock, of the package) until the lock directory is removed manually.

You need to delete that file. If you had the pacman package installed you could have simply used p_unlock() and the 00LOCK file is removed. You can't install pacman now until the 00LOCK file is removed.

To install pacman use:

install.packages("pacman")

There may be a second issue. This is where you somehow corrupted MASS. This can occur, in my experience, if you try to update a package while it is in use in another R session. I'm sure there's other ways to cause this as well. To solve this problem try:

1. Close out of all R sessions (use task manager to ensure you're truly R session free) Ctrl + Alt + Delete
2. Go to your library location Sys.getenv("R_LIBS_USER"). In your case this is: C:\Program Files\R\R-3.0.1\library
3. Manually delete the MASS package
4. Fire up a vanilla session of R
5. Install MASS via install.packages("MASS")

If any of this works please let me know what worked.

Try bellow code. This is help your code.

  $("#btnUpdate").on("click", function () {
            //alert("Alert Test");
            var url = 'http://cooktv.sndimg.com/webcook/sandbox/perf/topics.json';
            $.ajax({
                type: "GET",
                url: url,
                data: "{}",
                dataType: "json",
                contentType: "application/json; charset=utf-8",
                success: function (result) {
                    debugger;

                    $.each(result.callback, function (index, value) {
                        alert(index + ': ' + value.Name);
                    });
                },
                failure: function (result) { alert('Fail'); }
            });
        });

I could not access your url. Bellow error is shows

(SELECT ename FROM EMP WHERE empno = mgr)

There are no records in EMP that meet this criteria.

You need to self-join to get this relation.

SELECT e.ename AS Employee, e.empno, m.ename AS Manager, m.empno
FROM EMP AS e LEFT OUTER JOIN EMP AS m
ON e.mgr =m.empno;

EDIT:

The answer you selected will not list your president because it's an inner join. I'm thinking you'll be back when you discover your output isn't what your (I suspect) homework assignment required. Here's the actual test case:

> select * from emp;

 empno | ename |    job    | deptno | mgr  
-------+-------+-----------+--------+------
  7839 | king  | president |     10 |     
  7698 | blake | manager   |     30 | 7839
(2 rows)

> SELECT e.ename employee, e.empno, m.ename manager, m.empno
FROM emp AS e LEFT OUTER JOIN emp AS m
ON e.mgr =m.empno;

 employee | empno | manager | empno 
----------+-------+---------+-------
 king     |  7839 |         |      
 blake    |  7698 | king    |  7839
(2 rows)

The difference is that an outer join returns all the rows. An inner join will produce the following:

> SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM emp e, emp m
WHERE e.mgr = m.empno;

 ename | empno | manager | mgr  
-------+-------+---------+------
 blake |  7698 | king    | 7839
(1 row)

If you read the link you shared, the accepted answer is:

Hopefully you have some luck here.

I tried all these method but none worked for me. I removed .git file using rm -rf .git form the local repository and then again did git init and git add and routine commands. It worked.

Just do this. Then invalidate IntelliJ caches (File -> Invalidate Caches)

I solved it in XAMPP by uncommenting ;extension=php_openssl.dll in /apache/bin/php.ini despite phpinfo() telling me /php/php.ini was the loaded ini file.

EDIT: I guess Ezra answer is the best solution directly adding the extension line to the appropriate ini file.

(This is not a philosophical answer but more of a practical one). The requirement for static modifier is obvious which has been answered by others. Basically, since the interfaces cannot be instantiated, the only way to access its fields are to make them a class field -- static.

The reason behind the interface fields automatically becoming final (constant) is to prevent different implementations accidentally changing the value of interface variable which can inadvertently affect the behavior of the other implementations. Imagine the scenario below where an interface property did not explicitly become final by Java:

public interface Actionable {
    public static boolean isActionable = false;

    public void performAction();
}

public NuclearAction implements Actionable {

    public void performAction() {
        // Code that depends on isActionable variable
        if (isActionable) {
            // Launch nuclear weapon!!!
        }
    }
}

Now, just think what would happen if another class that implements Actionable alters the state of the interface variable:

public CleanAction implements Actionable  {

    public void performAction() {
        // Code that can alter isActionable state since it is not constant
        isActionable = true;
    }
}

If these classes are loaded within a single JVM by a classloader, then the behavior of NuclearAction can be affected by another class, CleanAction, when its performAction() is invoke after CleanAction's is executed (in the same thread or otherwise), which in this case can be disastrous (semantically that is).

Since we do not know how each implementation of an interface is going to use these variables, they must implicitly be final.

Here's the solution that works fine for me.

I just Saved the Excel file as an Excel 97-2003 Version.

Most suggestions will fail if there so much as a single leading or trailing space, which would matter if the file is being edited by hand. This would make it less susceptible in that case:

grep '^[[:blank:]]*ABB\.log[[:blank:]]*$' a.tmp

A simple while-read loop in shell would do this implicitly:

while read file
do 
  case $file in
    (ABB.log) printf "%s\n" "$file"
  esac
done < a.tmp

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

You can read the full documentation here.

To complement what @kieste has posted, which I think is the best way to have Maven build informations available in your code if you're using Spring-boot: the documentation at http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#production-ready-application-info is very useful.

You just need to activate actuators, and add the properties you need in your application.properties or application.yml

Automatic property expansion using Maven

You can automatically expand info properties from the Maven project using resource filtering. If you use the spring-boot-starter-parent you can then refer to your Maven ‘project properties’ via @..@ placeholders, e.g.

project.artifactId=myproject
project.name=Demo
project.version=X.X.X.X
project.description=Demo project for info endpoint

Just want to reiterate this will work in pandas >= 0.9.1:

In [2]: read_csv('sample.csv', dtype={'ID': object})
Out[2]: 
                           ID
0  00013007854817840016671868
1  00013007854817840016749251
2  00013007854817840016754630
3  00013007854817840016781876
4  00013007854817840017028824
5  00013007854817840017963235
6  00013007854817840018860166

I'm creating an issue about detecting integer overflows also.

EDIT: See resolution here: https://github.com/pydata/pandas/issues/2247

Update as it helps others:

To have all columns as str, one can do this (from the comment):

pd.read_csv('sample.csv', dtype = str)

To have most or selective columns as str, one can do this:

# lst of column names which needs to be string
lst_str_cols = ['prefix', 'serial']
# use dictionary comprehension to make dict of dtypes
dict_dtypes = {x : 'str'  for x in lst_str_cols}
# use dict on dtypes
pd.read_csv('sample.csv', dtype=dict_dtypes)

You have to use execute immediate (dynamic sql).

DECLARE 
v_owner varchar2(40); 
v_table_name varchar2(40); 
cursor get_tables is 
select distinct table_name,user 
from user_tables 
where lower(user) = 'schema_name'; 
begin 
open get_tables; 
loop
    fetch get_tables into v_table_name,v_owner; 
    EXIT WHEN get_tables%NOTFOUND;
    execute immediate 'INSERT INTO STATS_TABLE(TABLE_NAME,SCHEMA_NAME,RECORD_COUNT,CREATED) 
    SELECT ''' || v_table_name || ''' , ''' || v_owner ||''',COUNT(*),TO_DATE(SYSDATE,''DD-MON-YY'')     FROM ' || v_table_name; 
end loop;
CLOSE get_tables; 
END; 

This is what has worked for me in order to disable CORS between Spring boot and React

@Configuration
public class CorsConfig implements WebMvcConfigurer {

    /**
     * Overriding the CORS configuration to exposed required header for ussd to work
     *
     * @param registry CorsRegistry
     */

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedMethods("*")
                .allowedHeaders("*")
                .allowCredentials(true)
                .maxAge(4800);
    }
}

I had to modify the Security configuration also like below:

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().disable()
                    .cors().configurationSource(new CorsConfigurationSource() {

                @Override
                public CorsConfiguration getCorsConfiguration(HttpServletRequest request) {
                    CorsConfiguration config = new CorsConfiguration();
                    config.setAllowedHeaders(Collections.singletonList("*"));
                    config.setAllowedMethods(Collections.singletonList("*"));
                    config.addAllowedOrigin("*");
                    config.setAllowCredentials(true);
                    return config;
                }
            }).and()
                    .antMatcher("/api/**")
                    .authorizeRequests()
                    .anyRequest().authenticated()
                    .and().httpBasic()
                    .and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                    .and().exceptionHandling().accessDeniedHandler(apiAccessDeniedHandler());
        }

I would remove them. In my book, dead code like that should be considered errors because it makes you do a double-take and ask yourself "How would I ever execute that line?"

I wasn't satisfied with the rounded top and bottom to the shadow present in Deefour's solution so created my own.

inset box-shadow creates a nice uniform shadow with the top and bottom cut off.

To use this effect on the sides of your element, create two pseudo elements :before and :after positioned absolutely on the sides of the original element.

div:before, div:after {
  content: " ";
  height: 100%;
  position: absolute;
  top: 0;
  width: 15px;
}
div:before {
  box-shadow: -15px 0 15px -15px inset;
  left: -15px;
}
div:after {
  box-shadow: 15px 0 15px -15px inset;
  right: -15px;
}

div {
  background: #EEEEEE;
  height: 100px;
  margin: 0 50px;
  width: 100px;
  position: relative;
}

<div></div>

Edit

Depending on your design, you may be able to use clip-path, as shown in @Luke's answer. However, note that in many cases this still results in the shadow tapering off at the top and bottom as you can see in this example:

div {
  width: 100px;
  height: 100px;
  background: #EEE;
  box-shadow: 0 0 15px 0px #000;
  clip-path: inset(0px -15px 0px -15px);
  position: relative;
  margin: 0 50px;
}

<div></div>

I got same error. Because i used v4 alpha class names like carousel-control-next When i changed with v3, problem solved.

You might not have created the jar file properly:

ex: missing option m in jar creation

The following works:

jar -cvfm MyJar.jar Manifest.txt *.class

Here is my simple understanding.

Problem: The value 0.45 cannot be accurately be represented by a float and is rounded up to 0.450000018. Why is that?

Answer: An int value of 45 is represented by the binary value 101101. In order to make the value 0.45 it would be accurate if it you could take 45 x 10^-2 (= 45 / 10^2.) But that’s impossible because you must use the base 2 instead of 10.

So the closest to 10^2 = 100 would be 128 = 2^7. The total number of bits you need is 9 : 6 for the value 45 (101101) + 3 bits for the value 7 (111). Then the value 45 x 2^-7 = 0.3515625. Now you have a serious inaccuracy problem. 0.3515625 is not nearly close to 0.45.

How do we improve this inaccuracy? Well we could change the value 45 and 7 to something else.

How about 460 x 2^-10 = 0.44921875. You are now using 9 bits for 460 and 4 bits for 10. Then it’s a bit closer but still not that close. However if your initial desired value was 0.44921875 then you would get an exact match with no approximation.

So the formula for your value would be X = A x 2^B. Where A and B are integer values positive or negative. Obviously the higher the numbers can be the higher would your accuracy become however as you know the number of bits to represent the values A and B are limited. For float you have a total number of 32. Double has 64 and Decimal has 128.

Just loop...

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

This is my solution, wish useful for you:

public class Sheet : Grid
{

a demo:

Strive to make your recursive call Tail Recursion (recursion where the last statement is the recursive call). Once you have that, converting it to iteration is generally pretty easy.

I use the following directive that makes me and most users very happy! It uses moment for parsing and formatting. It looks a little bit like the one by SunnyShah, mentioned earlier.

angular.module('app.directives')

.directive('appDatetime', function ($window) {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function (scope, element, attrs, ngModel) {
            var moment = $window.moment;

            ngModel.$formatters.push(formatter);
            ngModel.$parsers.push(parser);

            element.on('change', function (e) {
                var element = e.target;
                element.value = formatter(ngModel.$modelValue);
            });

            function parser(value) {
                var m = moment(value);
                var valid = m.isValid();
                ngModel.$setValidity('datetime', valid);
                if (valid) return m.valueOf();
                else return value;
            }

            function formatter(value) {
                var m = moment(value);
                var valid = m.isValid();
                if (valid) return m.format("LLLL");
                else return value;

            }

        } //link
    };

}); //appDatetime

In my form i use it like this:

<label>begin: <input type="text" ng-model="doc.begin" app-datetime required /></label>
<label>end: <input type="text" ng-model="doc.end" app-datetime required /></label>

This will bind a timestamp (milliseconds since 1970) to doc.begin and doc.end.

I saw a good article which helped me out at the last moment .. I was trying to insert few rows in a table which had identity column but did it wrongly and have to delete back. Once I deleted the rows then my identity column got changed . I was trying to find an way to update the column which was inserted but - no luck. So, while searching on google found a link ..

1. Deleted the columns which was wrongly inserted
2. Use force insert using identity on/off (explained below)

http://beyondrelational.com/modules/2/blogs/28/posts/10337/sql-server-how-do-i-insert-an-explicit-value-into-an-identity-column-how-do-i-update-the-value-of-an.aspx

If you're using jQuery, it's as simple as this:

$('form').attr('action', 'myNewActionTarget.html');

In my case I don't have issues with ~/.composer.
So being inside Laravel app root folder, I did sudo chown -R $USER composer.lock and it was helpful.

Use the DATE function:

SELECT DATE(orders.date_purchased) AS date

Well, Instead of doing manual lint settings we can include all the lint settings at the top of our JS file itself e.g.

Declare all the global var in that file like:

/*global require,dojo,dojoConfig,alert */

Declare all the lint settings like:

/*jslint browser:true,sloppy:true,nomen:true,unparam:true,plusplus:true,indent:4 */

Hope this will help you :)

Let's do some examples, from simpler to more difficult.

1. The view method returns a tensor with the same data as the self tensor (which means that the returned tensor has the same number of elements), but with a different shape. For example:

   a = torch.arange(1, 17)  # a's shape is (16,)
   
   a.view(4, 4) # output below
     1   2   3   4
     5   6   7   8
     9  10  11  12
    13  14  15  16
   [torch.FloatTensor of size 4x4]
   
   a.view(2, 2, 4) # output below
   (0 ,.,.) = 
   1   2   3   4
   5   6   7   8
   
   (1 ,.,.) = 
    9  10  11  12
   13  14  15  16
   [torch.FloatTensor of size 2x2x4]
   

2. Assuming that -1 is not one of the parameters, when you multiply them together, the result must be equal to the number of elements in the tensor. If you do: a.view(3, 3), it will raise a RuntimeError because shape (3 x 3) is invalid for input with 16 elements. In other words: 3 x 3 does not equal 16 but 9.

3. You can use -1 as one of the parameters that you pass to the function, but only once. All that happens is that the method will do the math for you on how to fill that dimension. For example a.view(2, -1, 4) is equivalent to a.view(2, 2, 4). [16 / (2 x 4) = 2]

4. Notice that the returned tensor shares the same data. If you make a change in the "view" you are changing the original tensor's data:

   b = a.view(4, 4)
   b[0, 2] = 2
   a[2] == 3.0
   False
   

5. Now, for a more complex use case. The documentation says that each new view dimension must either be a subspace of an original dimension, or only span d, d + 1, ..., d + k that satisfy the following contiguity-like condition that for all i = 0, ..., k - 1, stride[i] = stride[i + 1] x size[i + 1]. Otherwise, contiguous() needs to be called before the tensor can be viewed. For example:

   a = torch.rand(5, 4, 3, 2) # size (5, 4, 3, 2)
   a_t = a.permute(0, 2, 3, 1) # size (5, 3, 2, 4)
   
   # The commented line below will raise a RuntimeError, because one dimension
   # spans across two contiguous subspaces
   # a_t.view(-1, 4)
   
   # instead do:
   a_t.contiguous().view(-1, 4)
   
   # To see why the first one does not work and the second does,
   # compare a.stride() and a_t.stride()
   a.stride() # (24, 6, 2, 1)
   a_t.stride() # (24, 2, 1, 6)
   

   Notice that for a_t, stride[0] != stride[1] x size[1] since 24 != 2 x 3

If you don't mind getting a new data frame object returned as opposed to updating the original Pandas .assign() will avoid SettingWithCopyWarning. Your example:

df = df.assign(B=df1['E'])

One liner answer to the above question is :-

let the two lists be list1 and list2, and your requirement is to ensure whether two lists have the same elements, then as per me, following will be the best approach :-

if ((len(list1) == len(list2)) and
   (all(i in list2 for i in list1))):
    print 'True'
else:
    print 'False'

The above piece of code will work per your need i.e. whether all the elements of list1 are in list2 and vice-verse.

But if you want to just check whether all elements of list1 are present in list2 or not, then you need to use the below code piece only :-

if all(i in list2 for i in list1):
    print 'True'
else:
    print 'False'

The difference is, the later will print True, if list2 contains some extra elements along with all the elements of list1. In simple words, it will ensure that all the elements of list1 should be present in list2, regardless of whether list2 has some extra elements or not.

In PowerShell v3, have a look at the Invoke-WebRequest and Invoke-RestMethod e.g.:

$msg = Read-Host -Prompt "Enter message"
$encmsg = [System.Web.HttpUtility]::UrlEncode($msg)
Invoke-WebRequest -Uri "http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$encmsg&encoding=windows-1255"

This is how I handle this case:

On the machine where I have access to Internet:

mkdir keystone-deps
pip download python-keystoneclient -d "/home/aviuser/keystone-deps"
tar cvfz keystone-deps.tgz keystone-deps

Then move the tar file to the destination machine that does not have Internet access and perform the following:

tar xvfz keystone-deps.tgz
cd keystone-deps
pip install python_keystoneclient-2.3.1-py2.py3-none-any.whl -f ./ --no-index

You may need to add --no-deps to the command as follows:

pip install python_keystoneclient-2.3.1-py2.py3-none-any.whl -f ./ --no-index --no-deps

I needed to rename features for XGBoost, and it didn't like any of these:

import re
regex = r"[!\"#$%&'()*+,\-.\/:;<=>?@[\\\]^_`{|}~ ]+"
X_trn.columns = X_trn.columns.str.replace(regex, '_', regex=True)
X_tst.columns = X_tst.columns.str.replace(regex, '_', regex=True)

This question is old, but still relevant.

If you want to compare two maps by their values matching their keys, you can do as follows:

public static <K, V> boolean mapEquals(Map<K, V> leftMap, Map<K, V> rightMap) {
    if (leftMap == rightMap) return true;
    if (leftMap == null || rightMap == null || leftMap.size() != rightMap.size()) return false;
    for (K key : leftMap.keySet()) {
        V value1 = leftMap.get(key);
        V value2 = rightMap.get(key);
        if (value1 == null && value2 == null)
            continue;
        else if (value1 == null || value2 == null)
            return false;
        if (!value1.equals(value2))
            return false;
    }
    return true;
}

... or just resultlist.RemoveAt(1) if you know exactly the index.

Private Function GetIPv4Address() As String
    GetIPv4Address = String.Empty
    Dim strHostName As String = System.Net.Dns.GetHostName()
    Dim iphe As System.Net.IPHostEntry = System.Net.Dns.GetHostEntry(strHostName)

    For Each ipheal As System.Net.IPAddress In iphe.AddressList
        If ipheal.AddressFamily = System.Net.Sockets.AddressFamily.InterNetwork Then
            GetIPv4Address = ipheal.ToString()
        End If
    Next

End Function

You can use the name property for that particular element. For example to set a border of 2px around an input element with name xyz, you can use;

$(function() {
    $("input[name = 'xyz']").css("border","2px solid red");
})

DEMO

I ran into the same problem. Placing a forward slash after the folder name worked for me.

ex: git add foldername/

$('input[name="mygroup"]').val([5])

I had the same problem on my Ubuntu 14.04 when tried to install TopTracker. I got such errors:

/usr/share/toptracker/bin/TopTracker: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version 'CXXABI_1.3.8' not found (required by /usr/share/toptracker/bin/TopTracker) /usr/share/toptracker/bin/TopTracker: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.21' not found (required by /usr/share/toptracker/bin/TopTracker) /usr/share/toptracker/bin/TopTracker: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version 'CXXABI_1.3.9' not found (required by /usr/share/toptracker/bin/TopTracker)

But I then installed gcc 4.9 version and problem gone:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9

String str = "abcdef";
char[] ch  = str.toCharArray();
for(char c : ch){
    int temp = (int)c;
    int temp_integer = 96; //for lower case
    if(temp<=122 & temp>=97)
        System.out.print(temp-temp_integer);
}

Output:

123456

@Shiki for Capital/UpperCase letters use the following code:

String str = "DEFGHI";
char[] ch  = str.toCharArray();
for(char c : ch){
    int temp = (int)c;
    int temp_integer = 64; //for upper case
    if(temp<=90 & temp>=65)
        System.out.print(temp-temp_integer);
}

Output:

456789

Type 3, in order to work would have to look like this:

(function($){
    //Attach this new method to jQuery
    $.fn.extend({     
        //This is where you write your plugin's name
        'pluginname': function(_options) {
            // Put defaults inline, no need for another variable...
            var options =  $.extend({
                'defaults': "go here..."
            }, _options);

            //Iterate over the current set of matched elements
            return this.each(function() {

                //code to be inserted here

            });
        }
    }); 
})(jQuery);

I am unsure why someone would use extend over just directly setting the property in the jQuery prototype, it is doing the same exact thing only in more operations and more clutter.

I wanted a solution to copy files modified after a certain date and time which mean't I need to use Get-ChildItem piped through a filter. Below is what I came up with:

$SourceFolder = "C:\Users\RCoode\Documents\Visual Studio 2010\Projects\MyProject"
$ArchiveFolder = "J:\Temp\Robin\Deploy\MyProject"
$ChangesStarted = New-Object System.DateTime(2013,10,16,11,0,0)
$IncludeFiles = ("*.vb","*.cs","*.aspx","*.js","*.css")

Get-ChildItem $SourceFolder -Recurse -Include $IncludeFiles | Where-Object {$_.LastWriteTime -gt $ChangesStarted} | ForEach-Object {
    $PathArray = $_.FullName.Replace($SourceFolder,"").ToString().Split('\') 

    $Folder = $ArchiveFolder

    for ($i=1; $i -lt $PathArray.length-1; $i++) {
        $Folder += "\" + $PathArray[$i]
        if (!(Test-Path $Folder)) {
            New-Item -ItemType directory -Path $Folder
        }
    }   
    $NewPath = Join-Path $ArchiveFolder $_.FullName.Replace($SourceFolder,"")

    Copy-Item $_.FullName -Destination $NewPath  
}

# mysqladmin -u root -p status

Output:

Enter password:
Uptime: 4  Threads: 1  Questions: 62  Slow queries: 0  Opens: 51  Flush tables: 1  Open tables: 45  Queries per second avg: 15.500

It means MySQL serer is running

If server is not running then it will dump error as follows

# mysqladmin -u root -p status

Output :

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

So Under Debian Linux you can type following command

# /etc/init.d/mysql status

Approach with React Native and Hooks:

You can wrap the TextInput into a new one that watches if the value changed and trigger the onChange function if it does.

import React, { useState, useEffect } from 'react';
import { View, TextInput as RNTextInput, Button } from 'react-native';

// New TextInput that triggers onChange when value changes.
// You can add more TextInput methods as props to it.
const TextInput = ({ onChange, value, placeholder }) => {

  // When value changes, you can do whatever you want or just to trigger the onChange function
  useEffect(() => {
    onChange(value);
  }, [value]);

  return (
    <RNTextInput
      onChange={onChange}
      value={value}
      placeholder={placeholder}
    />
  );
};

const Main = () => {

  const [myValue, setMyValue] = useState('');

  const handleChange = (value) => {
    setMyValue(value);
    console.log("Handling value");
  };

  const randomLetters = [...Array(15)].map(() => Math.random().toString(36)[2]).join('');

  return (
    <View>
      <TextInput
        placeholder="Write something here"
        onChange={handleChange}
        value={myValue}
      />
      <Button
        title='Change value with state'
        onPress={() => setMyValue(randomLetters)}
      />
    </View>
  );
};

export default Main;

For a super succinct with jQuery approach try:

<div onclick="$(this).toggleClass('newclass')">click me</div>

Or pure JS:

<div onclick="this.classList.toggle('newclass');">click me</div>

You really just need a single struct, and as mentioned in the comments the correct annotations on the field will yield the desired results. JSON is not some extremely variant data format, it is well defined and any piece of json, no matter how complicated and confusing it might be to you can be represented fairly easily and with 100% accuracy both by a schema and in objects in Go and most other OO programming languages. Here's an example;

package main

import (
    "fmt"
    "encoding/json"
)

type Data struct {
    Votes *Votes `json:"votes"`
    Count string `json:"count,omitempty"`
}

type Votes struct {
    OptionA string `json:"option_A"`
}

func main() {
    s := `{ "votes": { "option_A": "3" } }`
    data := &Data{
        Votes: &Votes{},
    }
    err := json.Unmarshal([]byte(s), data)
    fmt.Println(err)
    fmt.Println(data.Votes)
    s2, _ := json.Marshal(data)
    fmt.Println(string(s2))
    data.Count = "2"
    s3, _ := json.Marshal(data)
    fmt.Println(string(s3))
}

https://play.golang.org/p/ScuxESTW5i

Based on your most recent comment you could address that by using an interface{} to represent data besides the count, making the count a string and having the rest of the blob shoved into the interface{} which will accept essentially anything. That being said, Go is a statically typed language with a fairly strict type system and to reiterate, your comments stating 'it can be anything' are not true. JSON cannot be anything. For any piece of JSON there is schema and a single schema can define many many variations of JSON. I advise you take the time to understand the structure of your data rather than hacking something together under the notion that it cannot be defined when it absolutely can and is probably quite easy for someone who knows what they're doing.

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

Some of the comments mention this as well, but asp net core does all this work for you.

If you have a query string that matches the name it will be available in the controller.

https://myapi/some-endpoint/123?someQueryString=YayThisWorks

[HttpPost]
[Route("some-endpoint/{someValue}")]
public IActionResult SomeEndpointMethod(int someValue, string someQueryString)
    {
        Debug.WriteLine(someValue);
        Debug.WriteLine(someQueryString);
        return Ok();
    }

Ouputs:

123

YayThisWorks

Just change few snippet(use array_merge function):-

  $options['inputs']=array_merge($options['inputs'], $new_input);

first you have to import: import javax.swing.JOptionPane; then you can call it using this:

JOptionPane.showMessageDialog(null, 
                              "ALERT MESSAGE", 
                              "TITLE", 
                              JOptionPane.WARNING_MESSAGE);

the null puts it in the middle of the screen. put whatever in quotes under alert message. Title is obviously title and the last part will format it like an error message. if you want a regular message just replace it with PLAIN_MESSAGE. it works pretty well in a lot of ways mostly for errors.

Extension of @Vincent 's answer:

For lm() generated models:

summary(fit)$coefficients[,4]   ##P-values 
summary(fit)$r.squared          ##R squared values

For gls() generated models:

summary(fit)$tTable[,4]         ##P-values
##R-squared values are not generated b/c gls uses max-likelihood not Sums of Squares

To isolate an individual p-value itself, you'd add a row number to the code:

For example to access the p-value of the intercept in both model summaries:

summary(fit)$coefficients[1,4]
summary(fit)$tTable[1,4]  

• Note, you can replace the column number with the column name in each of the above instances:

  summary(fit)$coefficients[1,"Pr(>|t|)"]  ##lm 
  summary(fit)$tTable[1,"p-value"]         ##gls 
  

If you're still unsure of how to access a value form the summary table use str() to figure out the structure of the summary table:

str(summary(fit))

If someone is facing issue using texttocolumns function in UFT. Please try using below function.

myxl.Workbooks.Open myexcel.xls
myxl.Application.Visible = false `enter code here`
set mysheet = myxl.ActiveWorkbook.Worksheets(1)
Set objRange = myxl.Range("A1").EntireColumn
Set objRange2 = mysheet.Range("A1")
objRange.TextToColumns objRange2,1,1, , , , true

Here we are using coma(,) as delimiter.

Try this:

DateTime Date = DateTime.Now.AddHours(-DateTime.Now.Hour).AddMinutes(-DateTime.Now.Minute)
   .AddSeconds(-DateTime.Now.Second);

Output will be like:

07/29/2015 00:00:00

Libraries exist to do this, but the simplest plain Java way is to create a Map of List like this:

Map<Object,ArrayList<Object>> multiMap = new HashMap<>();

fstream are great but I will go a little deeper and tell you about RAII.

The problem with a classic example is that you are forced to close the file by yourself, meaning that you will have to bend your architecture to this need. RAII makes use of the automatic destructor call in C++ to close the file for you.

Update: seems that std::fstream already implements RAII so the code below is useless. I'll keep it here for posterity and as an example of RAII.

class FileOpener
{
public:
    FileOpener(std::fstream& file, const char* fileName): m_file(file)
    { 
        m_file.open(fileName); 
    }
    ~FileOpeneer()
    { 
        file.close(); 
    }

private:
    std::fstream& m_file;
};

You can now use this class in your code like this:

int nsize = 10;
char *somedata;
ifstream myfile;
FileOpener opener(myfile, "<path to file>");
myfile.read(somedata,nsize);
// myfile is closed automatically when opener destructor is called

Learning how RAII works can save you some headaches and some major memory management bugs.

Just change the "application/json" to "text/plain" and do not forget the JSON.stringify(request):

var request = {Company: sapws.dbName, UserName: username, Password: userpass};
    console.log(request);
    $.ajax({
        type: "POST",
        url: this.wsUrl + "/Login",
        contentType: "text/plain",
        data: JSON.stringify(request),

        crossDomain: true,
    });

var is not a member of inner class.

To access var, a pointer or reference to an outer class instance should be used. e.g. pOuter->var will work if the inner class is a friend of outer, or, var is public, if one follows C++ standard strictly.

Some compilers treat inner classes as the friend of the outer, but some may not. See this document for IBM compiler:

"A nested class is declared within the scope of another class. The name of a nested class is local to its enclosing class. Unless you use explicit pointers, references, or object names, declarations in a nested class can only use visible constructs, including type names, static members, and enumerators from the enclosing class and global variables.

Member functions of a nested class follow regular access rules and have no special access privileges to members of their enclosing classes. Member functions of the enclosing class have no special access to members of a nested class."

I was facing the same problem with my project.

My project was not able to find this archive: -

C:\Users\rakeshnarang\.m2\repository\org\hibernate\hibernate-core\5.3.7.Final

I went to this directory and deleted this folder.

Went back to eclipse and hit ALT + F5 to update the project.

The jar file was downloaded again and the problem was solved.

You should try this.

On OSX (Yosemite), I was having the same issue. After trying several of the other answers, I changed the install directory files to be owned by me:

cd /Applications/android-sdk-mac_x86

chown -R *

Where is my user account.

The problem I had with doing the root install is that some files were ending up in the root account home directory and others in mine once I started using Android Studio.

try {
    File img = new File("somefile.png");
    BufferedImage image = ImageIO.read(img ); 
    System.out.println(image);
} catch (IOException e) { 
    e.printStackTrace(); 
}

Example output for my image file:

BufferedImage@5d391d: type = 5 ColorModel: #pixelBits = 24 
numComponents = 3 color 
space = java.awt.color.ICC_ColorSpace@50a649 
transparency = 1 
has alpha = false 
isAlphaPre = false 
ByteInterleavedRaster: 
width = 800 
height = 600 
#numDataElements 3 
dataOff[0] = 2

You can run System.out.println(object); on just about any object and get some information about it.

Applying a rotation animation (without duration, thus no animation effect) is a simpler solution than either calling View.setRotation() or override View.onDraw method.

// substitude deltaDegrees for whatever you want
RotateAnimation rotate = new RotateAnimation(0f, deltaDegrees, 
    Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);  

// prevents View from restoring to original direction. 
rotate.setFillAfter(true); 

someButton.startAnimation(rotate);

Work 100% sure try this code for the get all hashmap key and value

static HashMap<String, String> map = new HashMap<>();

map.put("one"  " a " );
map.put("two"  " b " );
map.put("three"  " c " );
map.put("four"  " d " );

just call this method whenever you want to show the HashMap value

 private void ShowHashMapValue() {

        /**
         * get the Set Of keys from HashMap
         */
        Set setOfKeys = map.keySet();

/**
 * get the Iterator instance from Set
 */
        Iterator iterator = setOfKeys.iterator();

/**
 * Loop the iterator until we reach the last element of the HashMap
 */
        while (iterator.hasNext()) {
/**
 * next() method returns the next key from Iterator instance.
 * return type of next() method is Object so we need to do DownCasting to String
 */
            String key = (String) iterator.next();

/**
 * once we know the 'key', we can get the value from the HashMap
