My simple solution. IMHO it's the cleanest.

First create a application.yml

spring.main.allow-bean-definition-overriding: true

security:
  oauth2:
    client:
      clientId: XXX
      clientSecret: XXX
      accessTokenUri: XXX
      tokenName: access_token
      grant-type: client_credentials

Create the main class: Main

@SpringBootApplication
@EnableOAuth2Client
public class Main extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/").permitAll();
    }

    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);
    }

    @Bean
    public OAuth2RestTemplate oauth2RestTemplate(ClientCredentialsResourceDetails details) {
        return new OAuth2RestTemplate(details);
    }

}

Then Create the controller class: Controller

@RestController
class OfferController {

    @Autowired
    private OAuth2RestOperations restOperations;

    @RequestMapping(value = "/<your url>"
            , method = RequestMethod.GET
            , produces = "application/json")
    public String foo() {
        ResponseEntity<String> responseEntity = restOperations.getForEntity(<the url you want to call on the server>, String.class);
        return responseEntity.getBody();
    }
}

The problem is that the META-INF folder won't get filtered so multiple entries of NOTICE or LICENSE cause duplicates when building and it is tryed to copy them together.

Dirty Quick Fix:

Open the .jar file in your .gradle/caches/... folder (with a zip compatible tool) and remove or rename the files in the META-INF folder that cause the error (usally NOTICE or LICENSE). (I know thats also in the OP, but for me it was not really clear until I read the google forum)

EDIT:

This was fixed in 0.7.1. Just add the confilcting files to exclude.

android {
    packagingOptions {
        exclude 'META-INF/LICENSE'
    }
}

for me one solution for this problem was to add in sql.Open ... sslmode=disable

Try the following query:

;WITH CTE_DocTotal
 AS
 (
   SELECT SUM(Sale + VAT) AS DocTotal_1
   FROM PEDI_InvoiceDetail
   GROUP BY InvoiceNumber
 )

UPDATE CTE_DocTotal
SET DocTotal = CTE_DocTotal.DocTotal_1

Thank you so much! <%Response.Buffer = False%> worked like a charm! My asp/HTML table that was returning a blank page at about 2700 records. The following debugging lines helped expose the buffering problem: I replace the Do While loop as follows and played with my limit numbers to see what was happening:

Replace

Do While not rs.EOF

'etc .... your block of code that writes the table rows

rs.moveNext

Loop

with

Do While reccount < 2500

if rs.EOF then recount = 2501

'etc .... your block of code that writes the table rows

rs.moveNext

Loop

response.write "recount = " & recount

raise or lower the 2500 and 2501 to see if it is a buffer problem. for my record set, I could see that the blank page return, blank table, was happening at about 2700 records, good luck to all and thank you again for solving this problem! Such a simple great solution!

In SQL Server Management Studio of Any Version, Use BIT as Data Type

which will provide you with True or False Value options. in case you want to use Only 1 or 0 then you can use this method:

CREATE TABLE SampleBit(
    bar int NOT NULL CONSTRAINT CK_foo_bar CHECK (bar IN (-1, 0, 1))
)

But I will strictly advise BIT as The BEST Option. Hope fully it's help someone.

Put in your js file

                var url = window.location.href;
                console.log(url);
                console.log(~url.indexOf("#product-consulation"));
                if (~url.indexOf("#product-consulation")) {
                    console.log('YES');
                    // $('html, body').animate({
                    //     scrollTop: $('#header').offset().top - 80
                    // }, 1000);
                } else {
                    console.log('NOPE');
                }

Try this:

SELECT to_char(sysdate - (2 / 24), 'MM-DD-YYYY HH24') FROM DUAL

To test it using a new date instance:

SELECT to_char(TO_DATE('11/06/2015 00:00','dd/mm/yyyy HH24:MI') - (2 / 24), 'MM-DD-YYYY HH24:MI') FROM DUAL

Output is: 06-10-2015 22:00, which is the previous day.

I prefer to use border-spacing as it allows more flexibility. For instance, you could do

table {
  border-spacing: 0 2px;
}

Which would only collapse the vertical borders and leave the horizontal ones in tact, which is what it sounds like the OP was actually looking for.

Note that border-spacing: 0 is not the same as border-collapse: collapse. You will need to use the latter if you want to add your own border to a tr as seen here.

If you're using Apache POI 4.x, you can do that with:

 Cell c = row.getCell(3);
 if (c == null || c.getCellType() == CellType.Blank) {
    // This cell is empty
 }

For older Apache POI 3.x versions, which predate the move to the CellType enum, it's:

 Cell c = row.getCell(3);
 if (c == null || c.getCellType() == Cell.CELL_TYPE_BLANK) {
    // This cell is empty
 }

Don't forget to check if the Row is null though - if the row has never been used with no cells ever used or styled, the row itself might be null!

I do not think you can declare a string like that in c. You may only do that for const char* and of course you can not modify a const char * as it is const.

You may use dynamic char array but you will have to take care of the reallocation.

EDIT: in fact this syntax compiles correctly. Still you can should not modify what str points to if it is initialized in the way you do it (from string literal)

You can try using Putty (freeware). It is mainly known as a SSH client, but you can use for Telnet login as well

Which OS you are using ? For Windows : Go to Command Prompt

set path to www/{ur project}

For me : www/laravel5

Then type this command : composer install

It will automatically install all dependency in vendor/

jsonData = """{"from": {"id": "8", "name": "Mary Pinter"}, "message": "How ARE you?", "comments": {"count": 0}, "updated_time": "2012-05-01", "created_time": "2012-05-01", "to": {"data": [{"id": "1543", "name": "Honey Pinter"}, {"name": "Joe Schmoe"}]}, "type": "status", "id": "id_7"}"""

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        print("to_id:", dest.get('id', 'null'))

Try it:

>>> getTargetIds(jsonData)
to_id: 1543
to_id: null

Or, if you just want to skip over values missing ids instead of printing 'null':

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        if 'id' in to_id:
            print("to_id:", dest['id'])

So:

>>> getTargetIds(jsonData)
to_id: 1543

Of course in real life, you probably don't want to print each id, but to store them and do something with them, but that's another issue.

First, the class must implements the click listenener :

implements OnItemClickListener

Then set a listener to the ListView

yourList.setOnItemclickListener(this);

And finally, create the clic method:

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(MainActivity.this, "You Clicked at ",   
 Toast.LENGTH_SHORT).show();
}

Old style classes are still marginally faster for attribute lookup. This is not usually important, but it may be useful in performance-sensitive Python 2.x code:

In [3]: class A:
   ...:     def __init__(self):
   ...:         self.a = 'hi there'
   ...:

In [4]: class B(object):
   ...:     def __init__(self):
   ...:         self.a = 'hi there'
   ...:

In [6]: aobj = A()
In [7]: bobj = B()

In [8]: %timeit aobj.a
10000000 loops, best of 3: 78.7 ns per loop

In [10]: %timeit bobj.a
10000000 loops, best of 3: 86.9 ns per loop

[Update]

More recently, there is Amazon AWS ECR (Elastic Container Registry), which provides a Docker image registry to which you can control access by means of the AWS IAM access management service. ECR can also run a CVE (vulnerabilities) check on your image when you push it.

Once you create your ECR, and obtain the "URL" you can push and pull as required, subject to the permissions you create: hence making it private or public as you wish.

Pricing is by amount of data stored, and data transfer costs.

https://aws.amazon.com/ecr/

[Original answer]

If you do not want to use the Docker Hub itself, you can host your own Docker repository under Artifactory by JFrog:

https://www.jfrog.com/confluence/display/RTF/Docker+Repositories

which will then run on your own server(s).

Other hosting suppliers are available, eg CoreOS:

http://www.theregister.co.uk/2014/10/30/coreos_enterprise_registry/

which bought quay.io

All of these three solutions give the same results if the input is a string:

1.

def reverse(text):
    result = ""
    for i in range(len(text),0,-1):
        result += text[i-1]
    return (result)

2.

text[::-1]

3.

"".join(reversed(text))

Not sure if this is the answer you were looking for, but it worked for me. After spinning my wheels in Windows Firewall, I went back into SQL Server Configuration Manager, checked SQL Server Network Configuration, in the protocols for the instance I was working with look at TCP/IP. By default it seems mine was set to disabled, which allowed for instance connections on the local machine but not using SSMS on another machine. Enabling TCP/IP did the trick for me.

It really doesn't matter. Just make sure you name your variables and functions descriptively. Also be consistent.

Nowt worse than seeing code like this:

int anInt;                  // Great name for a variable there ...
int myVar = Func( anInt );  // And on this line a great name for a function and myVar
                            // lacks the consistency already, poorly, laid out! 

Edit: As pointed out by my commenter that consistency needs to be maintained across an entire team. As such it doesn't matter WHAT method you chose, as long as that consistency is maintained. There is no right or wrong method, however. Every team I've worked in has had different ideas and I've adapted to those.

It appears that at least one of your predictors ,x1, x2, or x3, has only one factor level and hence is a constant.

Have a look at

lapply(dataframe.df[c("x1", "x2", "x3")], unique)

to find the different values.

<offline> false </offline>

<localRepository>${user.home}/.m2/repository</localRepository>

to

<offline> true <offline>

<localRepository>${user.home}/.m2/repository</localRepository>

Change the offline tag from false to true .

I love how this is explained in the article Cool performance features of EclipseLink 2.5

Indexing Foreign Keys

The first feature is auto indexing of foreign keys. Most people incorrectly assume that databases index foreign keys by default. Well, they don't. Primary keys are auto indexed, but foreign keys are not. This means any query based on the foreign key will be doing full table scans. This is any OneToMany, ManyToMany or ElementCollection relationship, as well as many OneToOne relationships, and most queries on any relationship involving joins or object comparisons. This can be a major perform issue, and you should always index your foreign keys fields.

Using the code example below will return to you the bitmap :

BitmapFactory.decodeStream(getContentResolver().openInputStream(Uri.parse("content://com.whatsapp.provider.media/item/128752")))

After that you all know what you have to do.

A very important place where it is REQUIRED to use the key => value pair in foreach loop is to be mentioned. Suppose you would want to add a new/sub-element to an existing item (in another key) in the $features array. You should do the following:

foreach($features as $key => $feature) {
    $features[$key]['new_key'] = 'new value';  
} 

Instead of this:

foreach($features as $feature) {
    $feature['new_key'] = 'new value';  
} 

The big difference here is that, in the first case you are accessing the array's sub-value via the main array itself with a key to the element which is currently being pointed to by the array pointer.

While in the second (which doesn't work for this purpose) you are assigning the sub-value in the array to a temporary variable $feature which is unset after each loop iteration.

I have faced the same problem once:

Pattern ptr = Pattern.compile("^[a-zA-Z][\\']?[a-zA-Z\\s]+$");

The above failed!

Pattern ptr = Pattern.compile("(^[a-zA-Z][\\']?[a-zA-Z\\s]+$)");

The above worked with pattern within ( and ).

Use List<T>.Insert(0, item) or a LinkedList<T>.AddFirst().

You can actually write to a named pipe using its name, btw.

Open a command shell as Administrator to get around the default "Access is denied" error:

echo Hello > \\.\pipe\PipeName

Try this...

<a href="/path/to/image" download>
    <img src="/path/to/image" />
 </a>

Here is an option in bash scripts:

#!/bin/bash

GO_OS=${GO_OS:-"linux"}

function detect_os {
    # Detect the OS name
    case "$(uname -s)" in
      Darwin)
        host_os=darwin
        ;;
      Linux)
        host_os=linux
        ;;
      *)
        echo "Unsupported host OS. Must be Linux or Mac OS X." >&2
        exit 1
        ;;
    esac

   GO_OS="${host_os}"
}

detect_os

if [ "${GO_OS}" == "darwin" ]; then
    sed -i '' -e ...
else
    sed -i -e ...
fi

I wrote small js-utility to crop and resize image on front-end. Here is link on GitHub project. Also you can get blob from final image to send it.

import imageSqResizer from './image-square-resizer.js'

let resizer = new imageSqResizer(
    'image-input',
    300,
    (dataUrl) => 
        document.getElementById('image-output').src = dataUrl;
);
//Get blob
let formData = new FormData();
formData.append('files[0]', resizer.blob);

//get dataUrl
document.getElementById('image-output').src = resizer.dataUrl;

Another way to get to the deleted commit is with the git fsck command.

git fsck --lost-found

This will output something like at the last line:

dangling commit xyz

We can check that it is the same commit using reflog as suggested in other answers. Now we can do a git merge

git merge xyz

Note:
We cannot get the commit back with fsck if we have already run a git gc command which will remove the reference to the dangling commit.

Since x!=x returns the same boolean array with np.isnan(x) (because np.nan!=np.nan would return True), you could also write:

np.argwhere(x!=x)

However, I still recommend writing np.argwhere(np.isnan(x)) since it is more readable. I just try to provide another way to write the code in this answer.

Yeah, you'd need to have a javascript function triggered by an onclick that does an AJAX load of a page and then returns false, that way they won't be redirected in the browser. You could use the following in jQuery, if that's acceptable for your project:

<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript">
function doSomething() {
    $.get("somepage.php");
    return false;
}
</script>

<a href="#" onclick="doSomething();">Click Me!</a>

You could also do a post-back if you need to use form values (use the $.post() method).

Well System.Reflection.MethodBase.GetCurrentMethod().Name is not a very good choice 'cause it will just display the method name without additional information.

Like for string MyMethod(string str) the above property will return just MyMethod which is hardly adequate.

It is better to use System.Reflection.MethodBase.GetCurrentMethod().ToString() which will return the entire method signature...

A bit manual searching but its an alternative way...
Find the Oracle home or where the installation files for Oracle is installed on your linux server.

cd / <-- Goto root directory
find . -print| grep -i dbm*.sql

Result varies on how you installed Oracle but mine displays this

/db/oracle

Goto the folder

less /db/oracle/db1/sqlplus/doc/README.htm

scroll down and you should see something like this

SQL*Plus Release Notes - Release 11.2.0.2

A good question. In ZSH you can use the globbing modifier (D), which stands for "dotfiles". Compare:

ls $HOME/*

and

ls $HOME/*(D)

This correctly excludes the special directory entries . and ... In Bash you can use .* to include the dotfiles explicitly:

ls $HOME/* $HOME/.*

But that includes . and .. as well, so it's not what you were looking for. I'm sure there's some way to make * match dotfiles in bash, too.

You have stumbled over the general problem with encodings: How can I tell in which encoding a file is?

Answer: You can't unless the file format provides for this. XML, for example, begins with:

<?xml encoding="utf-8"?>

This header was carefully chosen so that it can be read no matter the encoding. In your case, there is no such hint, hence neither your editor nor Python has any idea what is going on. Therefore, you must use the codecs module and use codecs.open(path,mode,encoding) which provides the missing bit in Python.

As for your editor, you must check if it offers some way to set the encoding of a file.

The point of UTF-8 is to be able to encode 21-bit characters (Unicode) as an 8-bit data stream (because that's the only thing all computers in the world can handle). But since most OSs predate the Unicode era, they don't have suitable tools to attach the encoding information to files on the hard disk.

The next issue is the representation in Python. This is explained perfectly in the comment by heikogerlach. You must understand that your console can only display ASCII. In order to display Unicode or anything >= charcode 128, it must use some means of escaping. In your editor, you must not type the escaped display string but what the string means (in this case, you must enter the umlaut and save the file).

That said, you can use the Python function eval() to turn an escaped string into a string:

>>> x = eval("'Capit\\xc3\\xa1n\\n'")
>>> x
'Capit\xc3\xa1n\n'
>>> x[5]
'\xc3'
>>> len(x[5])
1

As you can see, the string "\xc3" has been turned into a single character. This is now an 8-bit string, UTF-8 encoded. To get Unicode:

>>> x.decode('utf-8')
u'Capit\xe1n\n'

Gregg Lind asked: I think there are some pieces missing here: the file f2 contains: hex:

0000000: 4361 7069 745c 7863 335c 7861 316e  Capit\xc3\xa1n

codecs.open('f2','rb', 'utf-8'), for example, reads them all in a separate chars (expected) Is there any way to write to a file in ASCII that would work?

Answer: That depends on what you mean. ASCII can't represent characters > 127. So you need some way to say "the next few characters mean something special" which is what the sequence "\x" does. It says: The next two characters are the code of a single character. "\u" does the same using four characters to encode Unicode up to 0xFFFF (65535).

So you can't directly write Unicode to ASCII (because ASCII simply doesn't contain the same characters). You can write it as string escapes (as in f2); in this case, the file can be represented as ASCII. Or you can write it as UTF-8, in which case, you need an 8-bit safe stream.

Your solution using decode('string-escape') does work, but you must be aware how much memory you use: Three times the amount of using codecs.open().

Remember that a file is just a sequence of bytes with 8 bits. Neither the bits nor the bytes have a meaning. It's you who says "65 means 'A'". Since \xc3\xa1 should become "à" but the computer has no means to know, you must tell it by specifying the encoding which was used when writing the file.

I know this is an old question, however here is a simple one-liner to switch it on or off depending on its current state:

set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'  -name ProxyEnable -value (-not ([bool](get-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'  -name ProxyEnable).proxyenable))

You can use a StringWriter to write values to a string. It provides a stream-like syntax (though does not derive from Stream) which works with an underlying StringBuilder.

The file extension may be case sentive...but the code works.

Set objFSO = CreateObject("Scripting.FileSystemObject")
  objStartFolder = "C:\Dev\"

  Set objFolder = objFSO.GetFolder(objStartFolder)
  Wscript.Echo objFolder.Path

  Set colFiles = objFolder.Files

  For Each objFile in colFiles
  strFileName = objFile.Name

  If objFSO.GetExtensionName(strFileName) = "pdf" Then
      Wscript.Echo objFile.Name
  End If

  Next
  Wscript.Echo

  ShowSubfolders objFSO.GetFolder(objStartFolder)

  Sub ShowSubFolders(Folder)
     For Each Subfolder in Folder.SubFolders
          Wscript.Echo Subfolder.Path
          Set objFolder = objFSO.GetFolder(Subfolder.Path)
          Set colFiles = objFolder.Files
          For Each objFile in colFiles
              Wscript.Echo objFile.Name
          Next
          Wscript.Echo
          ShowSubFolders Subfolder
      Next
  End Sub

The above answers are correct but I calling spyder within my virtualenv would still use my PATH to look up the version of spyder in my default anaconda env. I found this answer which gave the following workaround:

source activate my_env            # activate your target env with spyder installed
conda info -e                     # look up the directory of your conda env
find /path/to/my/env -name spyder # search for the spyder executable in your env
/path/to/my/env/then/to/spyder    # run that executable directly

I chose this over modifying PATH or adding a link to the executable at a higher priority in PATH since I felt this was less likely to break other programs. However, I did add an alias to the executable in ~/.bash_aliases.

If you want to to know how to return a value from stored procedure to Visual Basic.NET. Please read this tutorial: How to return a value from stored procedure

I used the following stored procedure to return the value.

CREATE PROCEDURE usp_get_count

AS
BEGIN
 DECLARE @VALUE int;

 SET @VALUE=(SELECT COUNT(*) FROM tblCar);

 RETURN @VALUE;

END
GO

This command:

iconv -f utf-8 -t utf-8 -c file.txt

will clean up your UTF-8 file, skipping all the invalid characters.

-f is the source format
-t the target format
-c skips any invalid sequence

Here is how I made it work with pytest 3.7.2 (installed via pip) and pycharms 2017.3:

1. Go to edit configurations

2. Add a new run config and select py.test

3. In the run config details, you need to set target=python and the unnamed field below to tests. It looks like this is the name of your test folder. Not too sure tough. I also recommend the -s argument so that if you debug your tests, the console will behave properly. Without the argument pytest captures the output and makes the debug console buggy.

4. My tests folder looks like that. This is just below the root of my project (my_project/tests).

5. My foobar_test.py file: (no imports needed):

def test_foobar():
    print("hello pytest")
    assert True

6. Run it with the normal run command

It does depend on the HTTP headers sent with the CSS files as both of the previous answers state - as long as you don't append any cachebusting stuff to the href. e.g.

<link href="/stylesheets/mycss.css?some_var_to_bust_cache=24312345" rel="stylesheet" type="text/css" />

Some frameworks (e.g. rails) put these in by default.

However If you get something like firebug or fiddler, you can see exactly what your browser is downloading on each request - which is expecially useful for finding out what your browser is doing, as opposed to just what it should be doing.

# it installs php7.3-gd for the moment
# and restarts PHP 7.3 FastCGI Process Manager: php-fpm7.3.
sudo apt-get install php-gd

# after I've restarted Nginx
sudo /etc/init.d/nginx restart

Works!

tl;dr

java.time.Instant                    // Represent a moment as seen in UTC. Internally, a count of nanoseconds since 1970-01-01T00:00Z.
.ofEpochSecond( 1_220_227_200L )     // Pass a count of whole seconds since the same epoch reference of 1970-01-01T00:00Z.

Know Your Data

People use various precisions in tracking time as a number since an epoch. So when you obtain some numbers to be interpreted as a count since an epoch, you must determine:

• What epoch?
  Many epochs dates have been used in various systems. Commonly used is POSIX/Unix time, where the epoch is the first moment of 1970 in UTC. But you should not assume this epoch.
• What precision?
  Are we talking seconds, milliseconds, microseconds, or nanoseconds since the epoch?
• What time zone?
  Usually a count since epoch is in UTC/GMT time zone, that is, has no time zone offset at all. But sometimes, when involving inexperienced or date-time ignorant programmers, there may be an implied time zone.

In your case, as others noted, you seem to have been given seconds since the Unix epoch. But you are passing those seconds to a constructor that expects milliseconds. So the solution is to multiply by 1,000.

Lessons learned:

• Determine, don't assume, the meaning of received data.
• Read the doc.

Your Data

Your data seems to be in whole seconds. If we assume an epoch of the beginning of 1970, and if we assume UTC time zone, then 1,220,227,200 is the first moment of the first day of September 2008.

Joda-Time

The java.util.Date and .Calendar classes bundled with Java are notoriously troublesome. Avoid them. Use instead either the Joda-Time library or the new java.time package bundled in Java 8 (and inspired by Joda-Time).

Note that unlike j.u.Date, a DateTime in Joda-Time truly knows its own assigned time zone. So in the example Joda-Time 2.4 code seen below, note that we first parse the milliseconds using the default assumption of UTC. Then, secondly, we assign a time zone of Paris to adjust. Same moment in the timeline of the Universe, but different wall-clock time. For demonstration, we adjust again, to UTC. Almost always better to explicitly specify your desired/expected time zone rather than rely on an implicit default (often the cause of trouble in date-time work).

We need milliseconds to construct a DateTime. So take your input of seconds, and multiply by a thousand. Note that the result must be a 64-bit long as we would overflow a 32-bit int.

long input = 1_220_227_200L;  // Note the "L" appended to long integer literals.
long milliseconds = ( input * 1_000L ); // Use a "long", not the usual "int". Note the appended "L".

Feed that count of milliseconds to constructor. That particular constructor assumes the count is from the Unix epoch of 1970. So adjust time zone as desired, after construction.

Use proper time zone names, a combination of continent and city/region. Never use 3 or 4 letter codes such as EST as they are neither standardized not unique.

DateTime dateTimeParis = new DateTime( milliseconds ).withZone( DateTimeZone.forID( "Europe/Paris" ) );

For demonstration, adjust the time zone again.

DateTime dateTimeUtc = dateTimeParis.withZone( DateTimeZone.UTC );
DateTime dateTimeMontréal = dateTimeParis.withZone( DateTimeZone.forID( "America/Montreal" ) );

Dump to console. Note how the date is different in Montréal, as the new day has begun in Europe but not yet in America.

System.out.println( "dateTimeParis: " + dateTimeParis );
System.out.println( "dateTimeUTC: " + dateTimeUtc );
System.out.println( "dateTimeMontréal: " + dateTimeMontréal );

When run.

dateTimeParis: 2008-09-01T02:00:00.000+02:00
dateTimeUTC: 2008-09-01T00:00:00.000Z
dateTimeMontréal: 2008-08-31T20:00:00.000-04:00

java.time

The makers of Joda-Time have asked us to migrate to its replacement, the java.time framework as soon as is convenient. While Joda-Time continues to be actively supported, all future development will be done on the java.time classes and their extensions in the ThreeTen-Extra project.

The java-time framework is defined by JSR 310 and built into Java 8 and later. The java.time classes have been back-ported to Java 6 & 7 on the ThreeTen-Backport project and to Android in the ThreeTenABP project.

An Instant is a moment on the timeline in UTC with a resolution of nanoseconds. Its epoch is the first moment of 1970 in UTC.

Instant instant = Instant.ofEpochSecond( 1_220_227_200L );

Apply an offset-from-UTC ZoneOffset to get an OffsetDateTime.

Better yet, if known, apply a time zone ZoneId to get a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

I found that none of the answers provided actually worked for me; what actually worked for me is to do:

git push --set-upstream origin *BRANCHNAME*

After creating a new branch, then it gets tracked properly. (I have Git 2.7.4)

I had taken .svn folder from my fellow developer and replaced my .svn folder with this. It worked for me. Don't know what may be other consequences!

I spent the entire morning solving a similar problem after having landed on this stack question. I used Dan's first solution in the answer above as the jump off point.

Problem

I have a dev (this is on my local machine), staging, and production environment. My staging and production environments live on the same server.

The app is deployed to staging via acmeserver/~staging/note-taking-app and the production version lives at acmeserver/note-taking-app (blame IT).

All the media files such as fonts were loading perfectly fine on dev (i.e., react-scripts start).

However, when I created and uploaded staging and production builds, while the .css and .js files were loading properly, fonts were not. The compiled .css file looked to have a correct path but the browser http request was getting some very wrong pathing (shown below).

The compiled main.fc70b10f.chunk.css file:

@font-face {
  font-family: SairaStencilOne-Regular;
  src: url(note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf) ("truetype");
}

The browser http request is shown below. Note how it is adding in /static/css/ when the font file just lives in /static/media/ as well as duplicating the destination folder. I ruled out the server config being the culprit.

The Referer is partly at fault too.

GET /~staging/note-taking-app/static/css/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf HTTP/1.1
Host: acmeserver
Origin: http://acmeserver
Referer: http://acmeserver/~staging/note-taking-app/static/css/main.fc70b10f.chunk.css

The package.json file had the homepage property set to ./note-taking-app. This was causing the problem.

{
  "name": "note-taking-app",
  "version": "0.1.0",
  "private": true,
  "homepage": "./note-taking-app",
  "scripts": {
    "start": "env-cmd -e development react-scripts start",
    "build": "react-scripts build",
    "build:staging": "env-cmd -e staging npm run build",
    "build:production": "env-cmd -e production npm run build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }
  //...
}

Solution

That was long winded — but the solution is to:

1. change the PUBLIC_URL env variable depending on the environment
2. remove the homepage property from the package.json file

Below is my .env-cmdrc file. I use .env-cmdrc over regular .env because it keeps everything together in one file.

{
  "development": {
    "PUBLIC_URL": "",
    "REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
  },
  "staging": {
    "PUBLIC_URL": "/~staging/note-taking-app",
    "REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
  },
  "production": {
    "PUBLIC_URL": "/note-taking-app",
    "REACT_APP_API": "http://acmeserver/note-taking-app/api"
  }
}

Routing via react-router-dom works fine too — simply use the PUBLIC_URL env variable as the basename property.

import React from "react";
import { BrowserRouter } from "react-router-dom";

const createRouter = RootComponent => (
  <BrowserRouter basename={process.env.PUBLIC_URL}>
    <RootComponent />
  </BrowserRouter>
);

export { createRouter };

The server config is set to route all requests to the ./index.html file.

Finally, here is what the compiled main.fc70b10f.chunk.css file looks like after the discussed changes were implemented.

@font-face {
  font-family: SairaStencilOne-Regular;
  src: url(/~staging/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf)
    format("truetype");
}

    Create React App assumes your application is hosted at the serving web server's root or a subpath as specified in package.json (homepage). Normally, Create React App ignores the hostname. You may use this variable to force assets to be referenced verbatim to the url you provide (hostname included). This may be particularly useful when using a CDN to host your application.

This can actually be done in CSS and very minimal JS just by adding a CSS class (don't set styles directly in JS!) with e.g. a ng-clickevent. The principle is that one can't animate height: 0; to height: auto; but this can be tricked by animating the max-height property. The container will expand to it's "auto-height" value when .foo-open is set - no need for fixed height or positioning.

.foo {
    max-height: 0;
}

.foo--open {
    max-height: 1000px; /* some arbitrary big value */
    transition: ...
}

see this fiddle by the excellent Lea Verou

As a concern raised in the comments, note that while this animation works perfectly with linear easing, any exponential easing will produce a behaviour different from what could be expected - due to the fact that the animated property is max-height and not height itself; specifically, only the height fraction of the easing curve of max-height will be displayed.

Aggregate in a subquery derived table and then join to it.

 Select Date, User, Status, Notes 
    from [SOMETABLE]
    inner join 
    (
        Select max(Date) as LatestDate, [User]
        from [SOMETABLE]
        Group by User
    ) SubMax 
    on [SOMETABLE].Date = SubMax.LatestDate
    and [SOMETABLE].User = SubMax.User 

The simplest way of doing this would be to add

include_directories(${CMAKE_SOURCE_DIR}/inc)
link_directories(${CMAKE_SOURCE_DIR}/lib)

add_executable(foo ${FOO_SRCS})
target_link_libraries(foo bar) # libbar.so is found in ${CMAKE_SOURCE_DIR}/lib

The modern CMake version that doesn't add the -I and -L flags to every compiler invocation would be to use imported libraries:

add_library(bar SHARED IMPORTED) # or STATIC instead of SHARED
set_target_properties(bar PROPERTIES
  IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/lib/libbar.so"
  INTERFACE_INCLUDE_DIRECTORIES "${CMAKE_SOURCE_DIR}/include/libbar"
)

set(FOO_SRCS "foo.cpp")
add_executable(foo ${FOO_SRCS})
target_link_libraries(foo bar) # also adds the required include path

If setting the INTERFACE_INCLUDE_DIRECTORIES doesn't add the path, older versions of CMake also allow you to use target_include_directories(bar PUBLIC /path/to/include). However, this no longer works with CMake 3.6 or newer.

I was looking for the answer of the same question but for a while I found my own solution and I wanted to share it for other people who will need those codes in the future. Here is another solution without function.

Dim control As Boolean
Dim controlval As String
Dim resultval As String
Dim i as Integer

controlval = "A1B2C3D4"

For i = 1 To Len(controlval)
control = IsNumeric(Mid(controlval, i, 1))
If control = True Then resultval = resultval & Mid(controlval, i, 1)
Next i

resultval = 1234

Another option is using command line:

code -d left.txt right.txt

Note: You may need to add code to your path first. See: How to call VS Code Editor from command line

I see you have all the settings right. You just need to end the local web server and start it again with

php artisan serve

Everytime you change your .env file, you need tor restart the server for the new options to take effect.

Or clear and cache your configuration with

php artisan config:cache

When you typed in sudo sendmailconfig, you should have been prompted to configure sendmail.

For reference, the files that are updated during configuration are located at the following (in case you want to update them manually):

/etc/mail/sendmail.conf
/etc/cron.d/sendmail
/etc/mail/sendmail.mc

You can test sendmail to see if it is properly configured and setup by typing the following into the command line:

$ echo "My test email being sent from sendmail" | /usr/sbin/sendmail [email protected]

The following will allow you to add smtp relay to sendmail:

#Change to your mail config directory:
cd /etc/mail

#Make a auth subdirectory
mkdir auth
chmod 700 auth

#Create a file with your auth information to the smtp server
cd auth
touch client-info

#In the file, put the following, matching up to your smtp server:
AuthInfo:your.isp.net "U:root" "I:user" "P:password"

#Generate the Authentication database, make both files readable only by root
makemap hash client-info < client-info
chmod 600 client-info
cd ..

Add the following lines to sendmail.mc, but before the MAILERDEFINITIONS. Make sure you update your smtp server.

define(`SMART_HOST',`your.isp.net')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash -o /etc/mail/auth/client-info.db')dnl

Invoke creation sendmail.cf (alternatively run make -C /etc/mail):

m4 sendmail.mc > sendmail.cf

Restart the sendmail daemon:

service sendmail restart

Replace [ with nothing, then ] with nothing.

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

I'd say export your server config in IIS manager:

1. In IIS manager, click the Server node
2. Go to Shared Configuration under "Management"
3. Click “Export Configuration”. (You can use a password if you are sending them across the internet, if you are just gonna move them via a USB key then don't sweat it.)

4. Move these files to your new server

   administration.config
   applicationHost.config
   configEncKey.key 
   

5. On the new server, go back to the “Shared Configuration” section and check “Enable shared configuration.” Enter the location in physical path to these files and apply them.

6. It should prompt for the encryption password(if you set it) and reset IIS.

BAM! Go have a beer!

This is arguably not the best way for most circumstances, but it's not been mentioned yet so perhaps it will help someone.

1. Bind mount host volume

   Host folder FOOBAR is mounted in container /volume/FOOBAR

2. Modify your container's startup script to find GID of the volume you're interested in

   $ TARGET_GID=$(stat -c "%g" /volume/FOOBAR)

3. Ensure your user belongs to a group with this GID (you may have to create a new group). For this example I'll pretend my software runs as the nobody user when inside the container, so I want to ensure nobody belongs to a group with a group id equal to TARGET_GID

  EXISTS=$(cat /etc/group | grep $TARGET_GID | wc -l)

  # Create new group using target GID and add nobody user
  if [ $EXISTS == "0" ]; then
    groupadd -g $TARGET_GID tempgroup
    usermod -a -G tempgroup nobody
  else
    # GID exists, find group name and add
    GROUP=$(getent group $TARGET_GID | cut -d: -f1)
    usermod -a -G $GROUP nobody
  fi

I like this because I can easily modify group permissions on my host volumes and know that those updated permissions apply inside the docker container. This happens without any permission or ownership modifications to my host folders/files, which makes me happy.

I don't like this because it assumes there's no danger in adding yourself to an arbitrary groups inside the container that happen to be using a GID you want. It cannot be used with a USER clause in a Dockerfile (unless that user has root privileges I suppose). Also, it screams hack job ;-)

If you want to be hardcore you can obviously extend this in many ways - e.g. search for all groups on any subfiles, multiple volumes, etc.

=TEXT(A1,"0000")

However the TEXT function is able to do other fancy stuff like date formating, aswell.

A simple alternative is to use the new sessionStorage object. Per the comments, if you have 'continue where I left off' checked, sessionStorage will persist between restarts.

You can also use LINQ to iterate over the array. or you can use the Find method which takes a delegate to search for it. However I think the find method is a bit more expensive then just looping through.

The following code worked for me:-

.nav-pills .nav-link.active, .nav-pills .show>.nav-link {
    color: #fff;
    background-color: rgba(0,123,255,.5);
}

Note:- This worked for me using Bootstrap 4

I want to add a point that you can also (and should if what you are writing is complex) add a test variable to rollback if you are in test mode. Then you can execute the whole thing at once. Often I also add code to see the before and after results of various operations especially if it is a complex script.

Example below:

USE AdventureWorks;
GO
DECLARE @TEST INT = 1--1 is test mode, use zero when you are ready to execute
BEGIN TRANSACTION;

BEGIN TRY
     IF @TEST= 1
        BEGIN
            SELECT *FROM Production.Product
                WHERE ProductID = 980;
        END    
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;

     IF @TEST= 1
        BEGIN
            SELECT *FROM Production.Product
                WHERE ProductID = 980;
            IF @@TRANCOUNT > 0
                ROLLBACK TRANSACTION;
        END    
END TRY

BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0 AND @TEST = 0
    COMMIT TRANSACTION;

When you need padding inside the JPanel generally you add padding with the layout manager you are using. There are cases that you can just expand the border of the JPanel.

The solution is the /Y switch:

xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y

I used a two query approach:

• first one to get count, min, max and avg
• second one (prepared statement) with a "LIMIT @count/2, 1" and "ORDER BY .." clauses to get the median value

These are wrapped in a function defn, so all values can be returned from one call.

If your ranges are static and your data does not change often, it might be more efficient to precompute/store these values and use the stored values instead of querying from scratch every time.

Send your file as a base64 string.

 var element = angular.element('<a/>');
                         element.attr({
                             href: 'data:attachment/csv;charset=utf-8,' + encodeURI(atob(response.payload)),
                             target: '_blank',
                             download: fname
                         })[0].click();

If attr method not working in Firefox You can also use javaScript setAttribute method

Here is a much faster solution based on hari's answer. The basic difference is that we keep a set of possible values for cells that don't have a value assigned. So when we try a new value, we only try valid values and we also propagate what this choice means for the rest of the sudoku. In the propagation step, we remove from the set of valid values for each cell the values that already appear in the row, column, or the same block. If only one number is left in the set, we know that the position (cell) has to have that value.

This method is known as forward checking and look ahead (http://ktiml.mff.cuni.cz/~bartak/constraints/propagation.html).

The implementation below needs one iteration (calls of solve) while hari's implementation needs 487. Of course my code is a bit longer. The propagate method is also not optimal.

For SQL Server 2008, the best and index friendly way is

DELETE from Table WHERE Date > CAST(GETDATE() as DATE);

For prior SQL Server versions, date maths will work faster than a convert to varchar. Even converting to varchar can give you the wrong result, because of regional settings.

DELETE from Table WHERE Date > DATEDIFF(d, 0, GETDATE());

_{Note: it is unnecessary to wrap the DATEDIFF with another DATEADD}

I Found this the most useful and easy to use https://wiki.python.org/moin/ConfigParserExamples

You just create a "myfile.ini" like:

[SectionOne]
Status: Single
Name: Derek
Value: Yes
Age: 30
Single: True

[SectionTwo]
FavoriteColor=Green
[SectionThree]
FamilyName: Johnson

[Others]
Route: 66

And retrieve the data like:

>>> import ConfigParser
>>> Config = ConfigParser.ConfigParser()
>>> Config
<ConfigParser.ConfigParser instance at 0x00BA9B20>
>>> Config.read("myfile.ini")
['c:\\tomorrow.ini']
>>> Config.sections()
['Others', 'SectionThree', 'SectionOne', 'SectionTwo']
>>> Config.options('SectionOne')
['Status', 'Name', 'Value', 'Age', 'Single']
>>> Config.get('SectionOne', 'Status')
'Single'

Some useful extensions:

extension String {
    func substring(from: Int, to: Int) -> String {
        let start = index(startIndex, offsetBy: from)
        let end = index(start, offsetBy: to - from)
        return String(self[start ..< end])
    }

    func substring(range: NSRange) -> String {
        return substring(from: range.lowerBound, to: range.upperBound)
    }
}

How to Use URIPathHelper class to get path from URI

val filePath = uriPathHelper.getPath(this, YOUR_URI_OBJECT)

Agree it is probably due to a problem in resources that is preventing build of R.Java in gen. In my case a cut n paste had given a duplicate app name in string. Sort the fault, delete gen directory and clean.

You can change the port number:

Open the server tab in eclipse -> right click open click on open---->you can change the port number.

Run the application with http://localhost:8080/Applicationname it will give output and also check http://localhost:8080/Applicationname/index.jsp

Yeah think of signing data as giving it your own wax stamp that nobody else has. It is done to achieve integrity and non-repudiation. Encryption is so no-one else can see the data. This is done to achieve confidentiality. See wikipedia http://en.wikipedia.org/wiki/Information_security#Key_concepts

A signature is a hash of your message signed using your private key.

Normally set does not keep the order, such as HashSet in order to quickly find a emelent, but you can try LinkedHashSet it will keep the order which you put in.

I found an easy way to get the dictionary value, and its name as well! I'm not sure yet about reading it back, I'm going to continue to do research and see if I can figure that out.

Here is the code:

your_dict = {'one': 1, 'two': 2}

variables = [var for var in dir() if var[0:2] != "__" and var[-1:-2] != "__"]

file = open("your_file","w")
for var in variables:
     if isinstance(locals()[var], dict):
          file.write(str(var) + " = " + str(locals()[var]) + "\n")
file.close()

Only problem here is this will output every dictionary in your namespace to the file, maybe you can sort them out by values? locals()[var] == your_dict for reference.

You can also remove if isinstance(locals()[var], dict): to output EVERY variable in your namespace, regardless of type. Your output looks exactly like your decleration your_dict = {'one': 1, 'two': 2}.

Hopefully this gets you one step closer! I'll make an edit if I can figure out how to read them back into the namespace :)

---EDIT---

Got it! I've added a few variables (and variable types) for proof of concept. Here is what my "testfile.txt" looks like:

string_test = Hello World
integer_test = 42
your_dict = {'one': 1, 'two': 2}

And here is the code the processes it:

import ast

file = open("testfile.txt", "r")
data = file.readlines()
file.close()

for line in data:
    var_name, var_val = line.split(" = ")
    for possible_num_types in range(3):  # Range is the == number of types we will try casting to
        try:
            var_val = int(var_val)
            break
        except (TypeError, ValueError):
            try:
                var_val = ast.literal_eval(var_val)
                break
            except (TypeError, ValueError, SyntaxError):
                var_val = str(var_val).replace("\n","")
                break
    locals()[var_name] = var_val


print("string_test =", string_test, " :  Type =", type(string_test))
print("integer_test =", integer_test, " :  Type =", type(integer_test))
print("your_dict =", your_dict, " :  Type =", type(your_dict))

This is what that outputs:

string_test = Hello World  :  Type = <class 'str'>
integer_test = 42  :  Type = <class 'int'>
your_dict = {'two': 2, 'one': 1}  :  Type = <class 'dict'>

I really don't like how the casting here works, the try-except block is bulky and ugly. Even worse, you cannot accept just any type! You have to know what you are expecting to take in. This wouldn't be nearly as bad if you only cared about dictionaries, but I really wanted something a bit more universal.

If anybody knows how to better cast these input vars I would LOVE to hear about it!

Regardless, this should still get you there :D I hope I've helped out!

I had the same thing on Windows 7 where I had the device properly set and the driver installed, and I was routinely running on the device. Then suddenly I started getting this error every time. I opened the Edit Configurations dialog as described above, switched to an emulator, tried one run, then went to the same dialog and changed back to USB. Then if worked again.

'a' in x

and a quick search reveals some nice information about it: http://docs.python.org/3/tutorial/datastructures.html#dictionaries

If you would use data.table package for the operations on data.frame then the problem is not present.

library(data.table)
dt = data.table(col1 = c("a","b","c"), col2 = 1:3)
sapply(dt, class)
#       col1        col2 
#"character"   "integer" 

If you have a factor columns in you dataset already and you want to convert them to character you can do the following.

library(data.table)
dt = data.table(col1 = factor(c("a","b","c")), col2 = 1:3)
sapply(dt, class)
#     col1      col2 
# "factor" "integer" 
upd.cols = sapply(dt, is.factor)
dt[, names(dt)[upd.cols] := lapply(.SD, as.character), .SDcols = upd.cols]
sapply(dt, class)
#       col1        col2 
#"character"   "integer" 

Not sure what you are trying to accomplish on your first few lines but you can try this:

$(document).ready(function()
{
    $("#ms_num").attr('maxlength','6');
});

import sys
sys.modules.keys()

An approximation of getting all imports for the current module only would be to inspect globals() for modules:

import types
def imports():
    for name, val in globals().items():
        if isinstance(val, types.ModuleType):
            yield val.__name__

This won't return local imports, or non-module imports like from x import y. Note that this returns val.__name__ so you get the original module name if you used import module as alias; yield name instead if you want the alias.

If you are using Notepad++ editor (like the tag of the question suggests), you can use the great "Find in Files" functionality.

Go to Search > Find in Files (Ctrl+Shift+F for the keyboard addicted) and enter:

• Find What = (test1|test2)
• Filters = *.txt
• Directory = enter the path of the directory you want to search in. You can check Follow current doc. to have the path of the current file to be filled.
• Search mode = Regular Expression

The simplest validation is as follows:

<form name="ff1" method="post">
  <input type="email" name="email" id="fremail" placeholder="[email protected]" />
  <input type="text" pattern="[a-z0-9. -]+" title="Please enter only alphanumeric characters." name="title" id="frtitle" placeholder="Title" />
  <input type="url" name="url" id="frurl" placeholder="http://yourwebsite.com/" />
  <input type="submit" name="Submit" value="Continue" />
</form>

It uses HTML5 attributes (like as pattern).

JavaScript: none.

Follow the steps given below as I also had the same problem:

$ git pull origin master --allow-unrelated-histories 

(To see if local branch can be easily merged with remote one)

$ git push -u origin master 

(Now push entire content of local git repository to your online repository)

You can get the nested value by repeating .get(), but with deeply nested maps you have to do a lot of casting into Map. An easier way is to use a generic method for getting a nested value.

Implementation

public static <T> T getNestedValue(Map map, String... keys) {
    Object value = map;

    for (String key : keys) {
        value = ((Map) value).get(key);
    }

    return (T) value;
}

Usage

// Map contents with string and even a list:
{
  "data": {
    "vehicles": {
      "list": [
        {
          "registration": {
            "owner": {
              "id": "3643619"
            }
          }
        }
      ]
    }
  }
}

List<Map> list = getNestedValue(mapContents, "data", "vehicles", "list");
Map first = list.get(0);
String id = getNestedValue(first, "registration", "owner", "id");

If the string was constructed in the same program, I would recommend using this:

String newline = System.getProperty("line.separator");
boolean hasNewline = word.contains(newline);

But if you are specced to use \n, this driver illustrates what to do:

class NewLineTest {
    public static void main(String[] args) {
        String hasNewline = "this has a newline\n.";
        String noNewline = "this doesn't";

        System.out.println(hasNewline.contains("\n"));
        System.out.println(hasNewline.contains("\\n"));
        System.out.println(noNewline.contains("\n"));
        System.out.println(noNewline.contains("\\n"));

    }

}

Resulted in

true
false
false
false

In reponse to your comment:

class NewLineTest {
    public static void main(String[] args) {
        String word = "test\n.";
        System.out.println(word.length());
        System.out.println(word);
        word = word.replace("\n","\n ");
        System.out.println(word.length());
        System.out.println(word);

    }

}

Results in

6
test
.
7
test
 .

Code here:

        $temp_arr = [];
        foreach ($a as $k => $v) {
            if(!is_null($v)) {
                $sum = isset($temp_arr[$v[0]]) ? ((int)$v[5] + $sum) : (int)$v[5];
                $temp_arr[$v[0]] = $sum;
            }
        }
        return $temp_arr;

Result:

{SEQ_OK: 1328,SEQ_ERROR: 561}

In my case, I don't got tmp folder setting up right. What I end up with these steps:

1. cd /

2. ln -s private/tmp /tmp

Adding a class with a width of 90% to your input element and adding the following input-icon class to your span would achieve what you want I think.

.input { width: 90%; }
.input-icon {
    display: inline-block;
    height: 22px;
    width: 22px;
    line-height: 22px;
    text-align: center;
    color: #000;
    font-size: 12px;
    font-weight: bold;
    margin-left: 4px;
}

EDIT Per dan's suggestion, it would not be wise to use .input as the class name, some more specific would be advised. I was simply using .input as a generic placeholder for your css

You need to transform your data to long format and shouldn't use $ inside aes:

DF <- read.table(text="Rank F1     F2     F3
1    500    250    50
2    400    100    30
3    300    155    100
4    200    90     10", header=TRUE)

library(reshape2)
DF1 <- melt(DF, id.var="Rank")

library(ggplot2)
ggplot(DF1, aes(x = Rank, y = value, fill = variable)) + 
  geom_bar(stat = "identity")

Seems that currently SWIG is best solution for this:

http://www.swig.org/Doc2.0/Go.html

It supports inheritance and even allows to subclass C++ class with Go struct so when overridden methods are called in C++ code, Go code is fired.

Section about C++ in Go FAQ is updated and now mentions SWIG and no longer says "because Go is garbage-collected it will be unwise to do so, at least naively".

The first answer is correct but you say that you are using cv2 which inherently uses numpy arrays. So, to make a complete different copy of say "myImage":

newImage = myImage.copy()

The above is enough. No need to import numpy.

Add below alias to your ~/.bash_profile, then run, source ~/.bash_profile; now anytime you need to see the updated files in the last commit, run, showfiles from your git repository.

alias showfiles='git show --pretty="format:" --name-only'

There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2

• With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.

  mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.html
  

• With the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).

  ## Prepare a temporary script that will serve as an editor.
  
  ## This script will be passed to ed.
  temp_script=$(mktemp)
  cat <<'EOF' >>"$temp_script"
  1a
  Content-Type: text/html
  .
  $r test.html
  w
  q
  EOF
  ## Call mailx, and tell it to invoke the editor script
  EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF
  ~e
  .
  EOF
  rm -f "$temp_script"
  

• With a general POSIX mailx, I don't know how to get at headers.

If you're going to use any mail or mailx, keep in mind that

• This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.

• When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.

If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.

mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html

Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.

cat <<'EOF' - test.html | /usr/sbin/sendmail -t
To: to@address
Subject: hello
Content-Type: text/html

EOF

Did you check your php.ini (check for the correct location with phpinfo()) if MySQL and the driver is installed correctly?

If you're using Eclipse, just have your WSDL in a .wsdl file, eclipse will validate it automatically.

From the Doc

The WSDL validator handles validation according to the 4 step process defined above. Steps 1 and 2 are both delegated to Apache Xerces (and XML parser). Step 3 is handled by the WSDL validator and any extension namespace validators (more on extensions below). Step 4 is handled by any declared custom validators (more on this below as well). Each step must pass in order for the next step to run.

DECLARE @date nvarchar(20)
SET @date ='2012-02-09 00:00:00'
SELECT DATEDIFF(day,cast(replace(cast(YEAR(@date) as char)+'-'+cast(MONTH(@date) as char)+'-01',' ','')+' 00:00:00' as datetime),dateadd(month,1,cast(replace(cast(YEAR(@date) as char)+'-'+cast(MONTH(@date) as char)+'-01',' ','')+' 00:00:00' as datetime)))

await blob.arrayBuffer() is good.

The problem is when iOS / Safari support is needed.. for that one would need this:

Blob.prototype.arrayBuffer ??=function(){ return new Response(this).arrayBuffer() }

Call To the following function with argument as you file path:

private String getFileContent(String targetFilePath){
           File file = new File(targetFilePath);
           try {
                    fileInputStream = new FileInputStream(file);
           }
           } catch (FileNotFoundException e) {
                  // TODO Auto-generated catch block
                  Log.e("",""+e.printStackTrace());
           }
           StringBuilder sb;
           while(fileInputStream.available() > 0) {

                 if(null== sb)  sb = new StringBuilder();

            sb.append((char)fileInputStream.read());
           }
       String fileContent;
       if(null!=sb){
            fileContent= sb.toString();
            // This is your fileContent in String.


       }
       try {
          fileInputStream.close();
       }
       catch(Exception e){
           // TODO Auto-generated catch block
           Log.e("",""+e.printStackTrace());
       }
           return fileContent;
}

The FormData class does work, however in iOS Safari (on the iPhone at least) I wasn't able to use Raphael Schweikert's solution as is.

Mozilla Dev has a nice page on manipulating FormData objects.

So, add an empty form somewhere in your page, specifying the enctype:

<form enctype="multipart/form-data" method="post" name="fileinfo" id="fileinfo"></form>

Then, create FormData object as:

var data = new FormData($("#fileinfo"));

and proceed as in Raphael's code.

You have to convert the type of your return value of the method to the Generic type which you pass to the method during calling.

    public static T values<T>()
    {
        Random random = new Random();
        int number = random.Next(1, 4);
        return (T)Convert.ChangeType(number, typeof(T));
    }

You need pass a type that is type casteable for the value you return through that method.

If you would want to return a value which is not type casteable to the generic type you pass, you might have to alter the code or make sure you pass a type that is casteable for the return value of method. So, this approach is not reccomended.

A good start would be validating the input. In other words, you can make sure that the user has indeed typed a correct path for a real existing file, like this:

import os
fileName = input("Please enter the name of the file you'd like to use.")
while not os.path.isfile(fileName):
    fileName = input("Whoops! No such file! Please enter the name of the file you'd like to use.")

This is with a little help from the built in module os, That is a part of the Standard Python Library.

A possible reason for an empty $_POST is that the request is not POST, or not POST anymore... It may have started out as post, but encountered a 301 or 302 redirect somewhere, which is switched to GET!

Inspect $_SERVER['REQUEST_METHOD'] to check if this is the case.

See https://stackoverflow.com/a/19422232/109787 for a good discussion of why this should not happen but still does.

I'd like to present a compact solution using a call by reference (yes, "batch" has pointers too!) to a function, and a "subfunction":

  @ECHO OFF
  SETLOCAL ENABLEDELAYEDEXPANSION

  SET /p NAME=- NAME ? 
  ECHO "%NAME%"
  CALL :TRIM NAME
  ECHO "%NAME%"
  GOTO :EOF

  :TRIM
  SetLocal EnableDelayedExpansion
  Call :TRIMSUB %%%1%%
  EndLocal & set %1=%tempvar%
  GOTO :EOF

  :TRIMSUB
  set tempvar=%*
  GOTO :EOF

According to this SO answer, it occurs due to an AWS SDK bug that appears to be solved in version 2.6.30 of the SDK, so updating the version to a newer, can help you fixing the problem.

Solution using React functional components.

import React, { useState, useRef, useEffect } from 'react'

const Modal = ({ title, show, onButtonClick }) => {

    const dialog = useRef({})

    useEffect(() => { $(dialog.current).modal(show ? 'show' : 'hide') }, [show])
    useEffect(() => { $(dialog.current).on('hide.bs.modal', () =>

There is a simpler answer to this than the answer given by the op in the question (the approach is the same):

Define the key in the web.config:

<add key="VersionNumber" value="06032014"/>

Make the call to appsettings directly from the aspx page:

<link href="styles/navigation.css?v=<%=ConfigurationManager.AppSettings["VersionNumber"]%>" rel="stylesheet" type="text/css" />

try table.Rows.add(row); after your for statement.

You need to decode it to convert it to a string. Check the answer here about bytes literal in python3.

In [1]: b'I posted a new photo to Facebook'.decode('utf-8')
Out[1]: 'I posted a new photo to Facebook'

Just grep through the working directory and send the output through the xargs command:

grep -lr '<<<<<<<' . | xargs git checkout --ours

or

grep -lr '<<<<<<<' . | xargs git checkout --theirs

How this works: grep will search through every file in the current directory (the .) and subdirectories recursively (the -r flag) looking for conflict markers (the string '<<<<<<<')

the -l or --files-with-matches flag causes grep to output only the filename where the string was found. Scanning stops after first match, so each matched file is only output once.

The matched file names are then piped to xargs, a utility that breaks up the piped input stream into individual arguments for git checkout --ours or --theirs

More at this link.

Since it would be very inconvenient to have to type this every time at the command line, if you do find yourself using it a lot, it might not be a bad idea to create an alias for your shell of choice: Bash is the usual one.

This method should work through at least Git versions 2.4.x

If you are using JPA to hibernate make sure the Entity has the correct data type for a field defined against a date column like use java.util.Date instead of String.

For an uglier version of unshift use splice:

TheArray.splice(0, 0, TheNewObject);

To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.

To install OpenSSL development package on Debian, Ubuntu or their derivatives:

$ sudo apt-get install libssl-dev

To install OpenSSL development package on Fedora, CentOS or RHEL:

$ sudo yum install openssl-devel 

Edit : As @isapir has pointed out, for Fedora version>=22 use the DNF package manager :

dnf install openssl-devel

Like all enum instances, Java instantiates each object when the class is loaded, with some guarantee that it's instantiated exactly once per JVM. Think of the INSTANCE declaration as a public static final field: Java will instantiate the object the first time the class is referred to.

The instances are created during static initialization, which is defined in the Java Language Specification, section 12.4.

For what it's worth, Joshua Bloch describes this pattern in detail as item 3 of Effective Java Second Edition.

You can use querySelectorAll:

    document.querySelectorAll('span[property=name]');

please try these

<form action="Delegate_update.php" method="post">
Name
<input type="text" name= "Name" value= "<?php echo $row['Name']; ?> "size=10>
Username
<input type="text" name= "User_name" value= "<?php echo $row['User_name']; ?> "size=10>
Password
<input type="text" name= "User_password" value= "<?php echo $row['User_password']; ?>" size=17>
<input type="submit" name= "submit" value="Update">
</form>

The first example nearly always wins in my book:

if(foo)
{
}

It's shorter and more concise. Why add an extra check to something when it's absolutely not needed? Just wasting cycles...

I do agree, though, that sometimes the more verbose syntax makes things more readable (which is ultimately more important as long as performance is acceptable) in situations where variables are poorly named.

If you're using bootstrap 3 date time picker, try this:

$('.selector').datetimepicker({ maxDate: $.now() });

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.* function are thin wrappers that basically do gca().*.

plt.subplot returns an axes object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.

import matplotlib.pyplot as plt

ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])


ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])

and so on for as many axes as you want.

or better, wrap it all up in a loop:

import matplotlib.pyplot as plt

DATA_x = ([1, 2],
          [2, 3],
          [3, 4])

DATA_y = DATA_x[::-1]

XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3

for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
    ax = plt.subplot(1, 3, j + 1)
    ax.scatter(x, y)
    ax.set_xlim(xlim)
    ax.set_ylim(ylim)

Java beans are special type of POJOs.

If you don't want to use external libs, then one solution is to recreate the reload method from python 2 for python 3 as below. Use this in the top of the module (assumes python 3.4+).

import sys
if(sys.version_info.major>=3):
    def reload(MODULE):        
        import importlib
        importlib.reload(MODULE)

BTW reload is very much required if you use python files as config files and want to avoid restarts of the application.....

I found an even elegant and simple solution to clearing cache

WebView obj;
obj.clearCache(true);

http://developer.android.com/reference/android/webkit/WebView.html#clearCache%28boolean%29

I have been trying to figure out the way to clear the cache, but all we could do from the above mentioned methods was remove the local files, but it never clean the RAM.

The API clearCache, frees up the RAM used by the webview and hence mandates that the webpage be loaded again.

I think no one actually has answered to the first question:

Why did they create those variables?

Those variables aren't strictly necessary. It's true. You can perfectly do something like this:

MONTH_CHOICES = (
    ("JANUARY", "January"),
    ("FEBRUARY", "February"),
    ("MARCH", "March"),
    # ....
    ("DECEMBER", "December"),
)

month = models.CharField(max_length=9,
                  choices=MONTH_CHOICES,
                  default="JANUARY")

Why using variables is better? Error prevention and logic separation.

JAN = "JANUARY"
FEB = "FEBRUARY"
MAR = "MAR"
# (...)

MONTH_CHOICES = (
    (JAN, "January"),
    (FEB, "February"),
    (MAR, "March"),
    # ....
    (DEC, "December"),
)

Now, imagine you have a view where you create a new Model instance. Instead of doing this:

new_instance = MyModel(month='JANUARY')

You'll do this:

new_instance = MyModel(month=MyModel.JAN)

In the first option you are hardcoding the value. If there is a set of values you can input, you should limit those options when coding. Also, if you eventually need to change the code at the Model layer, now you don't need to make any change in the Views layer.

If you have access to PHP 5.3, the intl extension is very nice for doing things like this.

Here's an example from the manual:

$fmt = new IntlDateFormatter( "en_US" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
    'America/Los_Angeles',IntlDateFormatter::GREGORIAN  );
$fmt->format(0); //0 for current time/date

In your case, you can do:

$fmt = new IntlDateFormatter( "en_US" ,IntlDateFormatter::FULL, IntlDateFormatter::FULL,
        'America/New_York');
 $fmt->format($datetime); //where $datetime may be a DateTime object, an integer representing a Unix timestamp value (seconds since epoch, UTC) or an array in the format output by localtime(). 

As you can set a Timezone such as America/New_York, this is much better than using a GMT or UTC offset, as this takes into account the day light savings periods as well.

Finaly, as the intl extension uses ICU data, which contains a lot of very useful features when it comes to creating your own date/time formats.

My solution is a quite simple approach in the way of using mostly given APIs. We use the feature of Map to export its content as Set via entrySet() method. We now have a Set containing Map.Entry objects.

Okay, a Set does not carry an order, but we can take the content an put it into an ArrayList. It now has an random order, but we will sort it anyway.

As ArrayList is a Collection, we now use the Collections.sort() method to bring order to chaos. Because our Map.Entry objects do not realize the kind of comparison we need, we provide a custom Comparator.

public static void main(String[] args) {
    HashMap<String, String> map = new HashMap<>();
    map.put("Z", "E");
    map.put("G", "A");
    map.put("D", "C");
    map.put("E", null);
    map.put("O", "C");
    map.put("L", "D");
    map.put("Q", "B");
    map.put("A", "F");
    map.put(null, "X");
    MapEntryComparator mapEntryComparator = new MapEntryComparator();

    List<Entry<String,String>> entryList = new ArrayList<>(map.entrySet());
    Collections.sort(entryList, mapEntryComparator);

    for (Entry<String, String> entry : entryList) {
        System.out.println(entry.getKey() + " : " + entry.getValue());
    }

}

Just to make a proper answer from the @Eddy Hernandez's comment and which is very correct since Alpine comes with ash not bash.

The question now referes to Starting a shell in the Docker Alpine container which implies using sh or ash or /bin/sh or /bin/ash/.

Based on the OP's question:

docker run image sh -c "cd /path/to/somewhere && python a.py"

• Make a project to put the files in.
  • File -> New -> Java Project
  • Make note of where that project was created (where your "workspace" is)
• Move your java files into the src folder which is immediately inside the project's folder.
  • Find the project INSIDE Eclipse's Package Explorer (Window -> Show View -> Package Explorer)
  • Double-click on the project, then double-click on the 'src' folder, and finally double-click on one of the java files inside the 'src' folder (they should look familiar!)
• Now you can run the files as expected.

Note the hollow 'J' in the image. That indicates that the file is not part of a project.

Override onDestroy of the Activity and Dismiss your Dialog & make it null

protected void onDestroy ()
    {
        if(mProgressDialog != null)
            if(mProgressDialog.isShowing())
                mProgressDialog.dismiss();
        mProgressDialog= null;
    }

OutputDebugString function will do it.

example code

    void CClass::Output(const char* szFormat, ...)
{

You need to add a name attribute to your dropdown list, then you need to add a required attribute, and then you can reference the error using myForm.[input name].$error.required:

HTML:

        <form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
        <input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
          <select name="service_id" class="Sitedropdown" style="width: 220px;"          
                  ng-model="ServiceID" 
                  ng-options="service.ServiceID as service.ServiceName for service in services"
                  required> 
            <option value="">Select Service</option> 
          </select> 
          <span ng-show="myForm.service_id.$error.required">Select service</span>

        </form>

    Controller:

        function Ctrl($scope) {
          $scope.services = [
            {ServiceID: 1, ServiceName: 'Service1'},
            {ServiceID: 2, ServiceName: 'Service2'},
            {ServiceID: 3, ServiceName: 'Service3'}
          ];

    $scope.save = function(myForm) {
    console.log('Selected Value: '+ myForm.service_id.$modelValue);
    alert('Data Saved! without validate');
    };
        }

Here's a working plunker.

This might be a late answer but this is the best around: https://github.com/eKoopmans/html2pdf

Pure javascript implementation. Allows you to specify just a single element by ID and convert it.

For sorting narrow range of integers try Counting sort, which has a complexity of O(range + n), where n is number of items to be sorted. If you'd like to sort something not discrete use optimal n*log(n) algorithms (quicksort, heapsort, mergesort). Merge sort is also used in a method already mentioned by other responses Arrays.sort. There is no simple way how to recommend some algorithm or function call, because there are dozens of special cases, where you would use some sort, but not the other.

So please specify the exact purpose of your application (to learn something (well - start with the insertion sort or bubble sort), effectivity for integers (use counting sort), effectivity and reusability for structures (use n*log(n) algorithms), or zou just want it to be somehow sorted - use Arrays.sort :-)). If you'd like to sort string representations of integers, than u might be interrested in radix sort....

Here's a little hack that switched from data-hover to data-toggle depending the screen width:

/**
 * Bootstrap nav menu hack
 */
$(window).on('load', function () {
    // On page load
    if ($(window).width() < 768) {
        $('.navbar-nav > li > .dropdown-toggle').removeAttr('data-hover').attr('data-toggle', 'dropdown');
    }

    // On window resize
    $(window).resize(function () {
        if ($(window).width() < 768) {
            $('.navbar-nav > li > .dropdown-toggle').removeAttr('data-hover').attr('data-toggle', 'dropdown');
        } else {
            $('.navbar-nav > li > .dropdown-toggle').removeAttr('data-toggle').attr('data-hover', 'dropdown');
        }
    });
});

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

Use a loop

for(var i = 0; i < obj.length; ++i){
   //do something with obj[i]
   for(var ind in obj[i]) {
        console.log(ind);
        for(var vals in obj[i][ind]){
            console.log(vals, obj[i][ind][vals]);
        }
   }
}

So basically I just made another div to wrap the pink and yellow, and I make that div have a float:left on it. The blue div has a float:right on it.

(so Windows releases it's hold on the file)

Instead, do Ctrl+Alt+Del right after the Stop of the service and kill the .exe of the service. Than, you can uninstall the service without rebooting. This happened to me in the past and it solves the part that you need to reboot.

What everyone is forgeting is explaining WHY this happens.

A Char, is basically an integer, but with a pointer in the ASCII table. All characters have a corresponding integer value as you can clearly see when trying to parse it.

Pranay has clearly a different character set, thats why HIS code doesnt work. the only way is

int val = '1' - '0';

because this looks up the integer value in the table of '0' which is then the 'base value' subtracting your number in char format from this will give you the original number.

Pretty late but this might help someone. The current answers assumes you are using the same file for your connections and models.

In real life, there is a high chance that you are splitting your models into different files. You can use something like this in your main file:

mongoose.connect('mongodb://localhost/default');

const db = mongoose.connection;

db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', () => {
  console.log('connected');
});

which is just how it is described in the docs. And then in your model files, do something like the following:

import mongoose, { Schema } from 'mongoose';

const userInfoSchema = new Schema({
  createdAt: {
    type: Date,
    required: true,
    default: new Date(),
  },
  // ...other fields
});

const myDB = mongoose.connection.useDb('myDB');

const UserInfo = myDB.model('userInfo', userInfoSchema);

export default UserInfo;

Where myDB is your database name.

Try setting 'clientCredentialType' to 'Windows' instead of 'Ntlm'.

I think that this is what the server is expecting - i.e. when it says the server expects "Negotiate,NTLM", that actually means Windows Auth, where it will try to use Kerberos if available, or fall back to NTLM if not (hence the 'negotiate')

I'm basing this on somewhat reading between the lines of: Selecting a Credential Type

// Use parse_url() function to parse the URL

This worked for me. I hope, it will also help you :)

A panel expands to a span (or a div), with it's content within it. A placeholder is just that, a placeholder that's replaced by whatever you put in it.

const int* ptr; 

declares ptr a pointer to const int type. You can modify ptr itself but the object pointed to by ptr shall not be modified.

const int a = 10;
const int* ptr = &a;  
*ptr = 5; // wrong
ptr++;    // right  

While

int * const ptr;  

declares ptr a const pointer to int type. You are not allowed to modify ptr but the object pointed to by ptr can be modified.

int a = 10;
int *const ptr = &a;  
*ptr = 5; // right
ptr++;    // wrong

Generally I would prefer the declaration like this which make it easy to read and understand (read from right to left):

int const  *ptr; // ptr is a pointer to constant int 
int *const ptr;  // ptr is a constant pointer to int

The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).

If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:

• Disaster Recovery: What to do when the SA account password is lost in SQL Server 2005
• Is there a way I can retrieve sa password in sql server 2005
• How to recover SA password on Microsoft SQL Server 2008 R2

Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.

You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).

As an aside, the login properties for sa would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.

I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):

• Recover access to a SQL Server instance
• More on Recovering Access to a SQL Server Instance

And some other resources:

• Connect to SQL Server When System Administrators Are Locked Out

• Leveraging Service SIDs to Logon to SQL Server Instances with Sysadmin Privileges

They JKS file is just a container for certificates and key pairs. In a client-side authentication scenario, the various parts of the keys will be located here:

• The client's store will contain the client's private and public key pair. It is called a keystore.
• The server's store will contain the client's public key. It is called a truststore.

The separation of truststore and keystore is not mandatory but recommended. They can be the same physical file.

To set the filesystem locations of the two stores, use the following system properties:

-Djavax.net.ssl.keyStore=clientsidestore.jks

and on the server:

-Djavax.net.ssl.trustStore=serversidestore.jks

To export the client's certificate (public key) to a file, so you can copy it to the server, use

keytool -export -alias MYKEY -file publicclientkey.cer -store clientsidestore.jks

To import the client's public key into the server's keystore, use (as the the poster mentioned, this has already been done by the server admins)

keytool -import -file publicclientkey.cer -store serversidestore.jks

Using sort -u does less I/O than sort | uniq, but the end result is the same. In particular, if the file is big enough that sort has to create intermediate files, there's a decent chance that sort -u will use slightly fewer or slightly smaller intermediate files as it could eliminate duplicates as it is sorting each set. If the data is highly duplicative, this could be beneficial; if there are few duplicates in fact, it won't make much difference (definitely a second order performance effect, compared to the first order effect of the pipe).

Note that there times when the piping is appropriate. For example:

sort FILE | uniq -c | sort -n

This sorts the file into order of the number of occurrences of each line in the file, with the most repeated lines appearing last. (It wouldn't surprise me to find that this combination, which is idiomatic for Unix or POSIX, can be squished into one complex 'sort' command with GNU sort.)

There are times when not using the pipe is important. For example:

sort -u -o FILE FILE

This sorts the file 'in situ'; that is, the output file is specified by -o FILE, and this operation is guaranteed safe (the file is read before being overwritten for output).

2019: I had to enter the password like 40 times... must be a bug... but it worked

Also with Kotlin:

fun SharedPreferences.Editor.putIntegerArrayList(key: String, list: ArrayList<Int>?): SharedPreferences.Editor {
    putString(key, list?.joinToString(",") ?: "")
    return this
}

fun SharedPreferences.getIntegerArrayList(key: String, defValue: ArrayList<Int>?): ArrayList<Int>? {
    val value = getString(key, null)
    if (value.isNullOrBlank())
        return defValue
    return ArrayList (value.split(",").map { it.toInt() }) 
}

Javascript is duck typed, so you can create a small structure.

function myFunction(value1,value2,value3)
{         
     var myObject = new Object();
     myObject.value2 = somevalue2;
     myObject.value3 = somevalue3;
     return myObject;
}


var value = myFunction("1",value2,value3);

if(value.value2  && value.value3)
{
//Do some stuff
}

If you are dealing with calculation, there are laws on how you should calculate and what precision you should use. If you fail that you will be doing something illegal. The only real reason is that the bit representation of decimal cases are not precise. As Basil simply put, an example is the best explanation. Just to complement his example, here's what happens:

static void theDoubleProblem1() {
    double d1 = 0.3;
    double d2 = 0.2;
    System.out.println("Double:\t 0,3 - 0,2 = " + (d1 - d2));

    float f1 = 0.3f;
    float f2 = 0.2f;
    System.out.println("Float:\t 0,3 - 0,2 = " + (f1 - f2));

    BigDecimal bd1 = new BigDecimal("0.3");
    BigDecimal bd2 = new BigDecimal("0.2");
    System.out.println("BigDec:\t 0,3 - 0,2 = " + (bd1.subtract(bd2)));
}

Output:

Double:  0,3 - 0,2 = 0.09999999999999998
Float:   0,3 - 0,2 = 0.10000001
BigDec:  0,3 - 0,2 = 0.1

Also we have that:

static void theDoubleProblem2() {
    double d1 = 10;
    double d2 = 3;
    System.out.println("Double:\t 10 / 3 = " + (d1 / d2));

    float f1 = 10f;
    float f2 = 3f;
    System.out.println("Float:\t 10 / 3 = " + (f1 / f2));

    // Exception! 
    BigDecimal bd3 = new BigDecimal("10");
    BigDecimal bd4 = new BigDecimal("3");
    System.out.println("BigDec:\t 10 / 3 = " + (bd3.divide(bd4)));
}

Gives us the output:

Double:  10 / 3 = 3.3333333333333335
Float:   10 / 3 = 3.3333333
Exception in thread "main" java.lang.ArithmeticException: Non-terminating decimal expansion

But:

static void theDoubleProblem2() {
    BigDecimal bd3 = new BigDecimal("10");
    BigDecimal bd4 = new BigDecimal("3");
    System.out.println("BigDec:\t 10 / 3 = " + (bd3.divide(bd4, 4, BigDecimal.ROUND_HALF_UP)));
}

Has the output:

BigDec:  10 / 3 = 3.3333 

You can use "find" for remove all files in the /objects directory with 0 in size with the command:

find .git/objects/ -size 0 -delete

Backup is recommended.

In case you want to get parts of an URL that you have stored in a variable, I can recommend URL-Parse

const Url = require('url-parse');
const url = new Url('https://github.com/foo/bar');

According to the documentation, it extracts the following parts:

The returned url instance contains the following properties:

protocol: The protocol scheme of the URL (e.g. http:). slashes: A boolean which indicates whether the protocol is followed by two forward slashes (//). auth: Authentication information portion (e.g. username:password). username: Username of basic authentication. password: Password of basic authentication. host: Host name with port number. hostname: Host name without port number. port: Optional port number. pathname: URL path. query: Parsed object containing query string, unless parsing is set to false. hash: The "fragment" portion of the URL including the pound-sign (#). href: The full URL. origin: The origin of the URL.

The 2nd document quoted by Peter Mortensen in his comment on the answer of Codesmith made things much clearer for me. That document was written by windowsinspired.com. The link repeated: A Better Way To Understand Quoting and Escaping of Windows Command Line Arguments.

Some further trial and error leads to the following guideline:

Escape every double quote " with a caret ^. If you want other characters with special meaning to the Windows command shell (e.g., <, >, |, &) to be interpreted as regular characters instead, then escape them with a caret, too.

If you want your program foo to receive the command line text "a\"b c" > d and redirect its output to file out.txt, then start your program as follows from the Windows command shell:

foo ^"a\^"b c^" ^> d > out.txt

If foo interprets \" as a literal double quote and expects unescaped double quotes to delimit arguments that include whitespace, then foo interprets the command as specifying one argument a"b c, one argument >, and one argument d.

If instead foo interprets a doubled double quote "" as a literal double quote, then start your program as

foo ^"a^"^"b c^" ^> d > out.txt

The key insight from the quoted document is that, to the Windows command shell, an unescaped double quote triggers switching between two possible states.

Some further trial and error implies that in the initial state, redirection (to a file or pipe) is recognized and a caret ^ escapes a double quote and the caret is removed from the input. In the other state, redirection is not recognized and a caret does not escape a double quote and isn't removed. Let's refer to these states as 'outside' and 'inside', respectively.

If you want to redirect the output of your command, then the command shell must be in the outside state when it reaches the redirection, so there must be an even number of unescaped (by caret) double quotes preceding the redirection. foo "a\"b " > out.txt won't work -- the command shell passes the entire "a\"b " > out.txt to foo as its combined command line arguments, instead of passing only "a\"b " and redirecting the output to out.txt.

foo "a\^"b " > out.txt won't work, either, because the caret ^ is encountered in the inside state where it is an ordinary character and not an escape character, so "a\^"b " > out.txt gets passed to foo.

The only way that (hopefully) always works is to keep the command shell always in the outside state, because then redirection works.

If you don't need redirection (or other characters with special meaning to the command shell), then you can do without the carets. If foo interprets \" as a literal double quote, then you can call it as

foo "a\"b c"

Then foo receives "a\"b c" as its combined arguments text and can interpret it as a single argument equal to a"b c.

Now -- finally -- to the original question. myscript '"test"' called from the Windows command shell passes '"test"' to myscript. Apparently myscript interprets the single and double quotes as argument delimiters and removes them. You need to figure out what myscript accepts as a literal double quote and then specify that in your command, using ^ to escape any characters that have special meaning to the Windows command shell. Given that myscript is also available on Unix, perhaps \" does the trick. Try

myscript \^"test\^"

or, if you don't need redirection,

myscript \"test\"

Try this formula in B2 cell

=IFERROR(INDEX($A$2:$A$7,MATCH(0,COUNTIF(B$1:$B1,$A$2:$A$7),0),1),"")

After click F2 and press Ctrl + Shift + Enter

First of all, this what is written in documentation. I think it is one of your class fields, not the main one - and how you want deserialiser to construct it back w/o parameterless construction ?

I think there is a workaround to make constructor private.

How do I create a new column with Groupby().Sum()?

There are two ways - one straightforward and the other slightly more interesting.

Everybody's Favorite: GroupBy.transform() with 'sum'

@Ed Chum's answer can be simplified, a bit. Call DataFrame.groupby rather than Series.groupby. This results in simpler syntax.

df.groupby('Date')['Data3'].transform('sum')

0     55

It's a tad faster,

df2 = pd.concat([df] * 12345)

%timeit df2['Data3'].groupby(df['Date']).transform('sum')
%timeit df2.groupby('Date')['Data3'].transform('sum')

10.4 ms ± 367 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
8.58 ms ± 559 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Unconventional, but Worth your Consideration: GroupBy.sum() + Series.map()

I stumbled upon an interesting idiosyncrasy in the API. From what I tell, you can reproduce this on any major version over 0.20 (I tested this on 0.23 and 0.24). It seems like you consistently can shave off a few milliseconds of the time taken by transform if you instead use a direct function of GroupBy and broadcast it using map:

df.Date.map(df.groupby('Date')['Data3'].sum())

0     55
1    108
2     66
3    121
4     55
5    108
6     66
7    121
Name: Date, dtype: int64

Compare with

df.groupby('Date')['Data3'].transform('sum')

0     55
1    108
2     66
3    121
4     55
5    108
6     66
7    121
Name: Data3, dtype: int64

My tests show that map is a bit faster if you can afford to use the direct GroupBy function (such as mean, min, max, first, etc). It is more or less faster for most general situations upto around ~200 thousand records. After that, the performance really depends on the data.

(Left: v0.23, Right: v0.24)

Nice alternative to know, and better if you have smaller frames with smaller numbers of groups. . . but I would recommend transform as a first choice. Thought this was worth sharing anyway.

Benchmarking code, for reference:

import perfplot

perfplot.show(
    setup=lambda n: pd.DataFrame({'A': np.random.choice(n//10, n), 'B': np.ones(n)}),
    kernels=[
        lambda df: df.groupby('A')['B'].transform('sum'),
        lambda df:  df.A.map(df.groupby('A')['B'].sum()),
    ],
    labels=['GroupBy.transform', 'GroupBy.sum + map'],
    n_range=[2**k for k in range(5, 20)],
    xlabel='N',
    logy=True,
    logx=True
)

Try

console.log(_x000D_
  new Date().toLocaleString().slice(9, -3)_x000D_
  , new Date().toString().slice(16, -15)_x000D_
);

After reviewing Microsoft's TechNet article "Azure Active Directory Cmdlets" -> section "Install the Azure AD Module", it seems that this process has been drastically simplified, thankfully.

As of 2016/06/30, in order to successfully execute the PowerShell commands Import-Module MSOnline and Connect-MsolService, you will need to install the following applications (64-bit only):

1. Applicable Operating Systems: Windows 7 to 10
   Name: "Microsoft Online Services Sign-in Assistant for IT Professionals RTW"
   Version: 7.250.4556.0 (latest)
   Installer URL: https://www.microsoft.com/en-us/download/details.aspx?id=41950
   Installer file name: msoidcli_64.msi
2. Applicable Operating Systems: Windows 7 to 10
   Name: "Windows Azure Active Directory Module for Windows PowerShell"
   Version: Unknown but the latest installer file's SHA-256 hash is D077CF49077EE133523C1D3AE9A4BF437D220B16D651005BBC12F7BDAD1BF313
   Installer URL: https://technet.microsoft.com/en-us/library/dn975125.aspx
   Installer file name: AdministrationConfig-en.msi
3. Applicable Operating Systems: Windows 7 only

If you want to return two objects you usually want to return a single object that encapsulates the two objects instead.

You could return a List of NamedObject objects like this:

public class NamedObject<T> {
  public final String name;
  public final T object;

  public NamedObject(String name, T object) {
    this.name = name;
    this.object = object;
  }
}

Then you can easily return a List<NamedObject<WhateverTypeYouWant>>.

Also: Why would you want to return a comma-separated list of names instead of a List<String>? Or better yet, return a Map<String,TheObjectType> with the keys being the names and the values the objects (unless your objects have specified order, in which case a NavigableMap might be what you want.

I know you don't want to obfuscate, but maybe you should check out dotfuscator, it will take your compiled assemblies and obfuscate them for you. I think it can even encrypt them.

Try below code to set view on specific location :-

            TextView textView = new TextView(getActivity());
            textView.setId(R.id.overflowCount);
            textView.setText(count + "");
            textView.setGravity(Gravity.CENTER);
            textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 12);
            textView.setTextColor(getActivity().getResources().getColor(R.color.white));
            textView.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    // to handle click 
                }
            });
            // set background 
            textView.setBackgroundResource(R.drawable.overflow_menu_badge_bg);

            // set apear

            textView.animate()
                    .scaleXBy(.15f)
                    .scaleYBy(.15f)
                    .setDuration(700)
                    .alpha(1)
                    .setInterpolator(new BounceInterpolator()).start();
            FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(
                    FrameLayout.LayoutParams.WRAP_CONTENT,
                    FrameLayout.LayoutParams.WRAP_CONTENT);
            layoutParams.topMargin = 100; // margin in pixels, not dps
            layoutParams.leftMargin = 100; // margin in pixels, not dps
            textView.setLayoutParams(layoutParams);

            // add into my parent view
            mainFrameLaout.addView(textView);

No one here posted an answer with all of the correct CSS variations, so here it is:

-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;

I wrote a directive you can use to bind an ng-model to any expression you want. Whenever the expression changes the model is set to the new value.

 module.directive('boundModel', function() {
      return {
        require: 'ngModel',
        link: function(scope, elem, attrs, ngModel) {
          var boundModel$watcher = scope.$watch(attrs.boundModel, function(newValue, oldValue) {
            if(newValue != oldValue) {
              ngModel.$setViewValue(newValue);
              ngModel.$render();
            }
          });

          // When $destroy is fired stop watching the change.
          // If you don't, and you come back on your state
          // you'll have two watcher watching the same properties
          scope.$on('$destroy', function() {
              boundModel$watcher();
          });
        }
    });

You can use it in your templates like this:

 <li>Total<input type="text" ng-model="total" bound-model="one * two"></li>      

Intel has been doing some open-source research on multithreading in Javascript, it was showcased recently on GDC 2012. Here is the link for the video. The research group used OpenCL which primarily focuses on Intel Chip sets and Windows OS. The project is code-named RiverTrail and the code is available on GitHub

I would generally prefer something a bit simpler, like activate/deactivate sub-resource (linked by a Link header with rel=service).

POST /groups/api/v1/groups/{group id}/activate

or

POST /groups/api/v1/groups/{group id}/deactivate

For the consumer, this interface is dead-simple, and it follows REST principles without bogging you down in conceptualizing "activations" as individual resources.

To summarize what was mentioned by Breno above

Say you have a variable with a path to a file

path = '/home/User/Desktop/myfile.py'

os.path.basename(path) returns the string 'myfile.py'

and

os.path.dirname(path) returns the string '/home/User/Desktop' (without a trailing slash '/')

These functions are used when you have to get the filename/directory name given a full path name.

In case the file path is just the file name (e.g. instead of path = '/home/User/Desktop/myfile.py' you just have myfile.py), os.path.dirname(path) returns an empty string.

I tried following with ASP.NET MVC 5, its works for me

var sessionData = "@Session["SessionName"]";

the window.onload event will fire when everything is loaded, including images etc.

You would want to check the DOM ready status if you wanted your js code to execute as early as possible, but you still need to access DOM elements.

Yes it is the correct way, but the synchronised block is required if you want all the removals together to be safe - unless the queue is empty no removals allowed. My guess is that you just want safe queue and dequeue operations, so you can remove the synchronised block.

However, there are far advanced concurrent queues in Java such as ConcurrentLinkedQueue

Use INSERT ... SELECT:

insert into your_table (c1, c2, ...)
select c1, c2, ...
from your_table
where id = 1

where c1, c2, ... are all the columns except id. If you want to explicitly insert with an id of 2 then include that in your INSERT column list and your SELECT:

insert into your_table (id, c1, c2, ...)
select 2, c1, c2, ...
from your_table
where id = 1

You'll have to take care of a possible duplicate id of 2 in the second case of course.

In this moment with the last version of the C# driver (2.3.0) the only way I found to get the database name specified in connection string is this:

var connectionString = @"mongodb://usr:[email protected],srv2.acme.net,srv3.acme.net/dbName?replicaSet=rset";
var mongoUrl = new MongoUrl(connectionString);
var dbname = mongoUrl.DatabaseName;
var db = new MongoClient(mongoUrl).GetDatabase(dbname);
db.GetCollection<MyType>("myCollectionName");

A concise way to do this is:

Map<Character,Integer> frequencies = new HashMap<>();
for (char ch : input.toCharArray()) 
   frequencies.put(ch, frequencies.getOrDefault(ch, 0) + 1);

We use a for-each to loop through every character. The frequencies.getOrDefault() gets value if key is present or returns(as default) its second argument.

Adding my solution here, as this is the thread that comes in google search. This is to get the next date of month, fixing any skips, keeping the next date within next month.

PHP adds current months total number of days to current date, if you do +1 month for example.

So applying +1 month to 30-01-2016 will return 02-03-2016. (Adding 31 days)

For my case, I needed to get 28-02-2016, so as to keep it within next month. In such cases you can use the solution below.

This code will identify if the given date's day is greater than next month's total days. If so It will subtract the days smartly and return the date within the month range.

Do note the return value is in timestamp format.

function getExactDateAfterMonths($timestamp, $months){
    $day_current_date            = date('d', $timestamp);
    $first_date_of_current_month = date('01-m-Y', $timestamp);
    // 't' gives last day of month, which is equal to no of days
    $days_in_next_month          = date('t',  strtotime("+".$months." months", strtotime($first_date_of_current_month)));

    $days_to_substract = 0;
    if($day_current_date > $days_in_next_month)
         $days_to_substract = $day_current_date - $days_in_next_month;

    $php_date_after_months   = strtotime("+".$months." months", $timestamp);
    $exact_date_after_months = strtotime("-".$days_to_substract." days", $php_date_after_months);

    return $exact_date_after_months;
}

getExactDateAfterMonths(strtotime('30-01-2016'), 1);
// $php_date_after_months   => 02-03-2016
// $exact_date_after_months => 28-02-2016

If you are using the portable XAMPP installation and Windows 7, and, like me have the version after they removed the XAMPP shell from the control panel none of the suggested answers here will do you much good as the packages will not install.

The problem is with the config file. I found the correct settings after a lot of trial and error.

Simply pull up a command window in the \xampp\php directory and run

pear config-set doc_dir :\xampp\php\docs\PEAR
pear config-set cfg_dir :\xampp\php\cfg
pear config-set data_dir :\xampp\php\data\PEAR
pear config-set test_dir :\xampp\php\tests
pear config-set www_dir :\xampp\php\www

you will want to replace the ':' with the actual drive letter that your portable drive is running on at the moment. Unfortunately, this needs to be done any time this drive letter changes, but it did get the module I needed installed.

Using react hooks, you can do following way

const [countryList, setCountries] = useState([]);


setCountries((countryList) => [
        ...countryList,
        "India",
      ]);

A possible soluttion that requires tweaking, but is very flexible is to use one of \big, \Big, \bigg,\Bigg in front of your division sign - these will make it progressively larger. For your formula, I think

  $\frac{a_1}{a_2} \Big/ \frac{b_1}{b_2}$

looks nicer than \middle\ which is automatically sized and IMHO is a bit too large.

This might be your script-free solution: http://davidwalsh.name/css-transform-rotate

It's supported in all browsers prefixed and, in IE10-11 and all still-used Firefox versions, unprefixed.

That means that if you don't care for old IEs (the bane of web designers) you can skip the -ms- and -moz- prefixes to economize space.

However, the Webkit browsers (Chrome, Safari, most mobile navigators) still need -webkit-, and there's a still-big cult following of pre-Next Opera and using -o- is sensate.

If we are talking about inexpensive implementation of the skip-list, I wonder in term of big O, what the cost of this operation is:

YourType[] array = someSet.toArray(new YourType[yourSet.size()]);

I mean it is always get stuck into a whole array creation, so it is O(n):

java.util.Arrays#copyOf

Here is what I use.

First day of the month:

date('Y-m-01');

Last day of the month:

date('Y-m-t');

Just Close() all active/existing forms and the application should exit.

I trained a neural network in Keras to perform non linear regression on some data. This is some part of my code for testing on new data using previously saved model configuration and weights.

fname = r"C:\Users\tauseef\Desktop\keras\tutorials\BestWeights.hdf5"
modelConfig = joblib.load('modelConfig.pkl')
recreatedModel = Sequential.from_config(modelConfig)
recreatedModel.load_weights(fname)
unseenTestData = np.genfromtxt(r"C:\Users\tauseef\Desktop\keras\arrayOf100Rows257Columns.txt",delimiter=" ")
X_test = unseenTestData
standard_scalerX = StandardScaler()
standard_scalerX.fit(X_test)
X_test_std = standard_scalerX.transform(X_test)
X_test_std = X_test_std.astype('float32')
unseenData_predictions = recreatedModel.predict(X_test_std)

This bizarre message means that the trustStore you specified was:

I think it's quite late for this answer. Anyway hope this will help somebody in the future. I faced the problem positioning the cards in angular. There are cards displayed for array of events. If image width of the event is big for card, the image should be shown by cropping from two sides and height of 100 %. If image height is long, images' bottom part is cropped and width is 100 %. Here is my pure css solution for this:

HTML:

 <span class="block clear img-card b-b b-light text-center" [ngStyle]="{'background-image' : 'url('+event.image+')'}"></span>

CSS

.img-card {
background-repeat: no-repeat;
background-size: cover;
background-position: 50% 50%;
width: 100%;
overflow: hidden;
}
