I ran into a similar error, but refering to Spring Webflow in a newly created Roo project. The solution for me turned out to be (Project) / right-click / Maven / Enable Maven Dependencies (followed by some restarts and republishes to Tomcat).

It appeared that STS or m2Eclipse was failing to push all the spring webflow jars into the web app lib directory. I'm not sure why. But enabling maven dependency handling and then rebuilding seemed to fix the problem; the webflow jars finally get published and thus it can find the schema namespace references.

I investigated this by exploring the tomcat directory that the web app was published to, clicking into WEB-INF/lib/ while it was running and noticing that it was missing webflow jar files.

You can send your data like the "POST" request through the "HEADERS".

Something like this:

$.ajax({
   url: "htttp://api.com/entity/list($body)",
   type: "GET",
   headers: ['id1':1, 'id2':2, 'id3':3],
   data: "",
   contentType: "text/plain",
   dataType: "json",
   success: onSuccess,
   error: onError
});

Add this at the start of main

ApplicationContext context = new ClassPathXmlApplicationContext("path/to/applicationContext.xml");

JobLauncher launcher=(JobLauncher)context.getBean("launcher");
Job job=(Job)context.getBean("job");

//Get as many beans you want
//Now do the thing you were doing inside test method
StopWatch sw = new StopWatch();
sw.start();
launcher.run(job, jobParameters);
sw.stop();
//initialize the log same way inside main
logger.info(">>> TIME ELAPSED:" + sw.prettyPrint());

This may be the easiest method

• Right click on the project and select "Add Service Reference..."
• In the Address: box, enter the physical path (C:\test\project....) of the downloaded/Modified wsdl.
• Hit Go

For UTF-8 textual information, you should use utf8_general_ci because...

• utf8_bin: compare strings by the binary value of each character in the string

• utf8_general_ci: compare strings using general language rules and using case-insensitive comparisons

a.k.a. it will should making searching and indexing the data faster/more efficient/more useful.

Well, since neither of the given replies helped me, I had to look more, and found solution in this article.

And the answer in a nutshell is the following:

Connecting to MySQL using MySQL Workbench

Connection Method: Standard TCP/IP over SSH
SSH Hostname: <Local VM IP Address (set in PuPHPet)>
SSH Username: vagrant (the default username)
SSH Password: vagrant (the default password)
MySQL Hostname: 127.0.0.1
MySQL Server Port: 3306
Username: root
Password: <MySQL Root Password (set in PuPHPet)>

Using given approach I was able to connect to mysql database in vagrant from host Ubuntu machine using MySQL Workbench and also using Valentina Studio.

Yes, you can.

From cplusplus.com:

Because these functions are operator overloading functions, the usual way in which they are called is:

   strm >> variable;

Where strm is the identifier of a istream object and variable is an object of any type supported as right parameter. It is also possible to call a succession of extraction operations as:

   strm >> variable1 >> variable2 >> variable3; //...

which is the same as performing successive extractions from the same object strm.

Just replace strm with cin.

A NULL column is not countable, however a row that has a NULL column is. So, this should do what you're looking for:

SELECT COUNT (*) FROM TABLE WHERE COL_NAME IS NULL OR LENGTH(TRIM (COL_NAME)) = 0

Note, that there are non-printing characters that this will not address. For example U+00A0 is the non-breaking space character and a line containing that will visually appear empty, but will not be found by the tests above.

    <table>
      <thead>
        <tr><th>title</th><th>price><th>number</th></tr>
      </thead>
      <tbody>
<?php
  foreach ($shop as $row) {
    echo '<tr>';
    foreach ($row as $item) {
      echo "<td>{$item}</td>";
    }
    echo '</tr>';
  }
?>
      </tbody>
    </table>

If it outputs to stderr as well you'll want to silence that. You can do that by redirecting file descriptor 2:

# Send stdout to out.log, stderr to err.log
myprogram > out.log 2> err.log

# Send both stdout and stderr to out.log
myprogram &> out.log      # New bash syntax
myprogram > out.log 2>&1  # Older sh syntax

# Log output, hide errors.
myprogram > out.log 2> /dev/null

I had the same issue with the following conditions:

• The resource files are in the same package as the java source files, in the java source folder (src/test/java).
• I build the project with maven on the command line and the build failed on the tests with the NullPointerException.
• The command line build did not copy the resource files to the test-classes folder, which explained the build failure.
• When going to eclipse after the command line build and rerun the tests in eclipse I also got the NullPointerException in eclipse.
• When I cleaned the project (deleted the content of the target folder) and rebuild the project in Eclipse the test did run correctly. This explains why it runs when you start with a clean project.

I fixed this by placing the resource files in the resources folder in test: src/test/resources using the same package structure as the source class.

BTW I used getClass().getResource(...)

HISTTIMEFORMAT="%d/%m/%y %H:%M "

For any commands typed prior to this, it will not help since they will just get a default time of when you turned history on, but it will log the time of any further commands after this.

If you want it to log history for permanent, you should put the following line in your ~/.bashrc

export HISTTIMEFORMAT="%d/%m/%y %H:%M "

use bytea (or Large Objects if you absolutely have to)

When making many plots, it makes sense to set it globally (relevant part is the second line, three lines together are a working example):

   library('ggplot2')
   theme_update(text = element_text(size=20))
   ggplot(mpg, aes(displ, hwy, colour = class)) + geom_point()

It looks like you need a MySQL server installed, there is install packages on mysql's site, or you can install through macports (I assume from the darwin11 line). I installed mine via ports, and the socket lives in /opt/local/var/run/mysql5/.

You need to restart Sublime completely in order for a theme to fully take effect. Just changing and saving Preferences.sublime-settings or using a theme-changing plugin won't do it. You need to use ?Q or Sublime Text -> Quit, not just close the window by clicking the red dot.

You would be best off using collections.defaultdict (added in Python 2.5). This allows you to specify the default object type of a missing key (such as a list).

So instead of creating a key if it doesn't exist first and then appending to the value of the key, you cut out the middle-man and just directly append to non-existing keys to get the desired result.

A quick example using your data:

>>> from collections import defaultdict
>>> data = [(2010, 2), (2009, 4), (1989, 8), (2009, 7)]
>>> d = defaultdict(list)
>>> d
defaultdict(<type 'list'>, {})
>>> for year, month in data:
...     d[year].append(month)
... 
>>> d
defaultdict(<type 'list'>, {2009: [4, 7], 2010: [2], 1989: [8]})

This way you don't have to worry about whether you've seen a digit associated with a year or not. You just append and forget, knowing that a missing key will always be a list. If a key already exists, then it will just be appended to.

Include in the GROUP BY clause all SELECT expressions that are not group function arguments.

For those using the context menu api, the docs are not immediately clear on how to obtain tab information.

  chrome.contextMenus.onClicked.addListener(function(info, tab) {
    console.log(info);
    return console.log(tab);
  });

https://developer.chrome.com/extensions/contextMenus

I like this better than any of the previous answers. It shows how to use the YAML format and lets you use a variable to specify the bucket.

    - PolicyName: "AllowIncomingBucket"
      PolicyDocument:
        Version: "2012-10-17"
        Statement:
          - Effect: "Allow"
            Action: "s3:*"
            Resource:
              - !Ref S3BucketArn
              - !Join ["/", [!Ref S3BucketArn, '*']]

Try this

function removeElements(){
    $('#models').html("");
}

try this code :

private GoogleMap mMap;


LocationManager locationManager;


private static final String TAG = "";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(map);
    mapFragment.getMapAsync(this);

    arrayPoints = new ArrayList<LatLng>();
}

@Override
public void onMapReady(GoogleMap googleMap) {


    mMap = googleMap;


    mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);


    LatLng myPosition;


    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling
        //    ActivityCompat#requestPermissions
        // here to request the missing permissions, and then overriding
        //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
        //                                          int[] grantResults)
        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }
    googleMap.setMyLocationEnabled(true);
    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    String provider = locationManager.getBestProvider(criteria, true);
    Location location = locationManager.getLastKnownLocation(provider);


    if (location != null) {
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
        LatLng latLng = new LatLng(latitude, longitude);
        myPosition = new LatLng(latitude, longitude);


        LatLng coordinate = new LatLng(latitude, longitude);
        CameraUpdate yourLocation = CameraUpdateFactory.newLatLngZoom(coordinate, 19);
        mMap.animateCamera(yourLocation);
    }
}

}

Dont forget to add permissions on AndroidManifest.xml.

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

FuzzyFinder has been mentioned, however I love the textmate like behaviour of the FuzzyFinderTextmate plugin which extends the behaviour to include all subdirs.

Make sure you are using version 2.16 of fuzzyfinder.vim - The higher versions break the plugin.

The fact that the sort values in the OP are integers isn't relevant to the question per se. In other words, the accepted answer would work if the sort value was text. I bring this up to also point out that the sort can be modified during the sort (for example, to account for upper and lower case).

>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: x[1])
[(148, 'ABC'), (221, 'DEF'), (121, 'abc'), (231, 'def')]
>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: str.lower(x[1]))
[(121, 'abc'), (148, 'ABC'), (231, 'def'), (221, 'DEF')]

Here is the example:

var charCode = "a".charCodeAt(0);_x000D_
console.log(charCode);

Or if you have longer strings:

var string = "Some string";_x000D_
_x000D_
for (var i = 0; i < string.length; i++) {_x000D_
  console.log(string.charCodeAt(i));_x000D_
}

String.charCodeAt(x) method will return ASCII character code at a given position.

Here is another solution:

for(String serverId : serverIds) {
   sb.append(",");
   sb.append(serverId); 
}

String resultingString = "";
if ( sb.length() > 1 ) {
    resultingString = sb.substring(1);
}

You should use

$this->db->where('$accommodation >=', minvalue);
$this->db->where('$accommodation <=', maxvalue);

I'm not sure of syntax, so I beg your pardon if it's not correct.
Anyway BETWEEN is implemented using >=min && <=max.
This is the meaning of my example.

EDITED:
Looking at this link I think you could write:

$this->db->where("$accommodation BETWEEN $minvalue AND $maxvalue");

If example is not final then a simple reassignment would work:

example = new String[example.length];

This assumes you need the array to remain the same size. If that's not necessary then create an empty array:

example = new String[0];

If it is final then you could null out all the elements:

Arrays.fill( example, null );

• See: void Arrays#fill(Object[], Object)
• Consider using an ArrayList or similar collection

A bit old, but I thought sharing how I'd do it, based on chubbsondubs' answer: I use FrameLayout (see Documentation), since it is used to contain a single view, and inflate into it the view from the xml.

Code following:

public class MyView extends FrameLayout {
    public MyView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        initView();
    }

    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initView();
    }

    public MyView(Context context) {
        super(context);
        initView();
    }

    private void initView() {
        inflate(getContext(), R.layout.my_view_layout, this);
    }
}

Sure, you can use equals if you want to go along with the crowd, but if you really want to amaze your fellow programmers check for inequality like this:

if ("success" != statusCheck.intern())

intern method is part of standard Java String API.

Your constructor is expecting one parameter (data). You're not passing it in the call. I guess you wanted to initialise a field in the object. That would look like this:

class DHT:
    def __init__(self):
        self.data = {}
        self.data['one'] = '1'
        self.data['two'] = '2'
        self.data['three'] = '3'
    def showData(self):
        print(self.data)

if __name__ == '__main__':
    DHT().showData()

Or even just:

class DHT:
    def __init__(self):
        self.data = {'one': '1', 'two': '2', 'three': '3'}
    def showData(self):
        print(self.data)

Because the join() method is in the string class, instead of the list class?

I agree it looks funny.

See http://www.faqs.org/docs/diveintopython/odbchelper_join.html:

Historical note. When I first learned Python, I expected join to be a method of a list, which would take the delimiter as an argument. Lots of people feel the same way, and there’s a story behind the join method. Prior to Python 1.6, strings didn’t have all these useful methods. There was a separate string module which contained all the string functions; each function took a string as its first argument. The functions were deemed important enough to put onto the strings themselves, which made sense for functions like lower, upper, and split. But many hard-core Python programmers objected to the new join method, arguing that it should be a method of the list instead, or that it shouldn’t move at all but simply stay a part of the old string module (which still has lots of useful stuff in it). I use the new join method exclusively, but you will see code written either way, and if it really bothers you, you can use the old string.join function instead.

I typically use this approach:

declare @s varchar(50)
set @s = 'TEST         TEST'
select REPLACE(REPLACE(REPLACE(@s,' ','[o][c]'),'[c][o]',''),'[o][c]',' ')

I see you're using unsigned integers. By definition, in C (I don't know about C++), unsigned arithmetic does not overflow ... so, at least for C, your point is moot :)

With signed integers, once there has been overflow, undefined behaviour (UB) has occurred and your program can do anything (for example: render tests inconclusive). 

#include <limits.h>

int a = <something>;
int x = <something>;
a += x;              /* UB */
if (a < 0) {         /* Unreliable test */
  /* ... */
}

To create a conforming program, you need to test for overflow before generating said overflow. The method can be used with unsigned integers too:

// For addition
#include <limits.h>

int a = <something>;
int x = <something>;
if ((x > 0) && (a > INT_MAX - x)) /* `a + x` would overflow */;
if ((x < 0) && (a < INT_MIN - x)) /* `a + x` would underflow */;

// For subtraction
#include <limits.h>
int a = <something>;
int x = <something>;
if ((x < 0) && (a > INT_MAX + x)) /* `a - x` would overflow */;
if ((x > 0) && (a < INT_MIN + x)) /* `a - x` would underflow */;

// For multiplication
#include <limits.h>

int a = <something>;
int x = <something>;
// There may be a need to check for -1 for two's complement machines.
// If one number is -1 and another is INT_MIN, multiplying them we get abs(INT_MIN) which is 1 higher than INT_MAX
if ((a == -1) && (x == INT_MIN)) /* `a * x` can overflow */
if ((x == -1) && (a == INT_MIN)) /* `a * x` (or `a / x`) can overflow */
// general case
if (a > INT_MAX / x) /* `a * x` would overflow */;
if ((a < INT_MIN / x)) /* `a * x` would underflow */;

For division (except for the INT_MIN and -1 special case), there isn't any possibility of going over INT_MIN or INT_MAX.

Use beginUpdates and endUpdates to insert a new cell when the button clicked.

As @vadian said in comment, begin/endUpdates has no effect for a single insert/delete/move operation

First of all, append data in your tableview array

Yourarray.append([labeltext])  

Then update your table and insert a new row

// Update Table Data
tblname.beginUpdates()
tblname.insertRowsAtIndexPaths([
NSIndexPath(forRow: Yourarray.count-1, inSection: 0)], withRowAnimation: .Automatic)
tblname.endUpdates()

This inserts cell and doesn't need to reload the whole table but if you get any problem with this, you can also use tableview.reloadData()

Swift 3.0

tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: yourArray.count-1, section: 0)], with: .automatic)
tableView.endUpdates()

Objective-C

[self.tblname beginUpdates];
NSArray *arr = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:Yourarray.count-1 inSection:0]];
[self.tblname insertRowsAtIndexPaths:arr withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tblname endUpdates];

The rule for using spinlocks is simple: use a spinlock if and only if the real time the lock is held is bounded and sufficiently small.

Note that usually user implemented spinlocks DO NOT satisfy this requirement because they do not disable interrupts. Unless pre-emptions are disabled, a pre-emption whilst a spinlock is held violates the bounded time requirement.

Sufficiently small is a judgement call and depends on the context.

Exception: some kernel programming must use a spinlock even when the time is not bounded. In particular if a CPU has no work to do, it has no choice but to spin until some more work turns up.

Special danger: in low level programming take great care when multiple interrupt priorities exist (usually there is at least one non-maskable interrupt). In this higher priority pre-emptions can run even if interrupts at the thread priority are disabled (such as priority hardware services, often related to the virtual memory management). Provided a strict priority separation is maintained, the condition for bounded real time must be relaxed and replaced with bounded system time at that priority level. Note in this case not only can the lock holder be pre-empted but the spinner can also be interrupted; this is generally not a problem because there's nothing you can do about it.

Toad for MySQL by Quest is free for non-commercial use. I really like the interface and it's quite powerful if you have several databases to work with (for example development, test and production servers).

From the website:

Toad® for MySQL is a freeware development tool that enables you to rapidly create and execute queries, automate database object management, and develop SQL code more efficiently. It provides utilities to compare, extract, and search for objects; manage projects; import/export data; and administer the database. Toad for MySQL dramatically increases productivity and provides access to an active user community.

Keep it simple :

• if you used post so you will need the body of the request, so you will need body-parser.

• No need to install body-parser with express, but you have to use it if you will receive post request.

  app.use(bodyParser.urlencoded({ extended: false }));

  { extended: false } false meaning, you do not have nested data inside your body object.

  Note that: the request data embedded within the request as a body Object.

On my machine, because of the way I have things set up, doing:

cd ~             # /work1/jleffler
cd ~jleffler     # /u/jleffler

The first pays attention to the value of environment variable $HOME; I deliberately set my $HOME to a local file system instead of an NFS-mounted file system. The second reads from the password file (approximately; NIS complicates things a bit) and finds that the password file says my home directory is /u/jleffler and changes to that directory.

The annoying stuff is that most software behaves as above (and the POSIX specification for the shell requires this behaviour). I use some software (and I don't have much choice about using it) that treats the information from the password file as the current value of $HOME, which is wrong.

Applying this to the question - as others have pointed out, 'cd ~x' goes to the home directory of user 'x', and more generally, whenever tilde expansion is done, ~x means the home directory of user 'x' (and it is an error if user 'x' does not exist).

It might be worth mentioning that:

cd ~-       # Change to previous directory ($OLDPWD)
cd ~+       # Change to current directory ($PWD)

I can't immediately find a use for '~+', unless you do some weird stuff with moving symlinks in the path leading to the current directory.

You can also do:

cd -

That means the same as ~-.

I had the same requirement - I just use this. User enters the number of days by which he/she wants to limit the calendar range to.

  SELECT DAY, offset
    FROM (SELECT to_char(SYSDATE, 'DD-MON-YYYY') AS DAY, 0 AS offset
            FROM DUAL
          UNION ALL
          SELECT to_char(SYSDATE - rownum, 'DD-MON-YYYY'), rownum
            FROM all_objects d)
            where offset <= &No_of_days

I use the above result set as driving view in LEFT OUTER JOIN with other views involving tables which have dates.

If you want to regain the 8080 port number you do so by opening the task manager and then process tab, right click java.exe process and click on end process as shown in image attached.

The LocalLinks extension from the most popular answer didn't work for me (given, I was trying to use file:// to open a directory in windows explorer, not a file), so I looked into another workaround. I found that this "Open in IE" extension is a good workaround: https://chrome.google.com/webstore/detail/open-in-ie/iajffemldkkhodaedkcpnbpfabiglmdi

This isn't an ideal fix, as instead of clicking the link, users will have to right-click and choose Open in IE, but it at least makes the link functional.

One thing to note though, in IE10 (and IE9 after a certain update point) you will have to add the site to your Trusted Sites (Internet Options > Security > Trusted sites). If the site is not in trusted sites, the file:// link does not work in IE either.

If you run a batch file calling PowerShell as a administrator, you better run it like this, saving you all the trouble:

powershell.exe -ExecutionPolicy Bypass -Command "Path\xxx.ps1"

It is better to use Bypass...

I like to keep the original array and return a copy. This is a generic version:

public static <T> T[] reverse(T[] array) {
    T[] copy = array.clone();
    Collections.reverse(Arrays.asList(copy));
    return copy;
}

without keeping the original array:

public static <T> void reverse(T[] array) {
    Collections.reverse(Arrays.asList(array));
}

More info... Some times .swp files might be holded by vm that was running in backgroung. You may see permission denied message when try to delete the files.

Try to not use the -W parameter and leave the password in blank. Sometimes the user is created with no-password.

If that doesn't work reset the password. There are several ways to do it, but this works on many systems:

$ su root
$ su postgres
$ psql -h localhost
> ALTER USER postgres with password 'YourNewPassword';

For anyone coming across this years later:

TL;DR check your pip version (2 vs 3)

I had this same issue and it was not fixed by running pip install simplejson despite pip insisting that it was installed. Then I realized that I had both python 2 and python 3 installed.

> python -V
Python 2.7.12
> pip -V
pip 9.0.1 from /usr/local/lib/python3.5/site-packages (python 3.5)

Installing with the correct version of pip is as easy as using pip2:

> pip2 install simplejson

and then python 2 can import simplejson fine.

Why do you want a textarea to submit when you hit enter?

A "text" input will submit by default when you press enter. It is a single line input.

<input type="text" value="...">

A "textarea" will not, as it benefits from multi-line capabilities. Submitting on enter takes away some of this benefit.

<textarea name="area"></textarea>

You can add JavaScript code to detect the enter keypress and auto-submit, but you may be better off using a text input.

For me what did the trick was running the command

git config auto.crlf false

inside the folder of the project, I wanted it specifically for one project.

That command changed the file in path {project_name}/.git/config (fyi .git is a hidden folder) by adding the lines

[auto]
    crlf = false

at the end of the file. I suppose changing the file does the same trick as well.

            var anim = $('.modal-dialog').removeClass('bounceInDown').addClass('fadeOutDownBig'); // Model Come class Remove & Out effect class add
            if (timeoutHandler) clearTimeout(timeoutHandler);
            timeoutHandler = setTimeout(function() {
                $('.modal-dialog').removeClass('fadeOutDownBig').addClass('bounceInDown'); // Model Out class Remove & Come effect class add
            }, 500); // some delay for complete Animation
        });
    });
    </script>

You can simply use $_GET especially if you know the othervar's name. If you want to be on the safe side, use if (isset ($_GET ['varname'])) to test for existence.

I would guess that ISO-format is a good idea. (Wikipedia article, also with time info)

Alternatively, while in your screen session all you have to do is type exit

This will kill the shell session initiated by the screen, which effectively terminates the screen session you are on.

No need to bother with screen session id, etc.

In kruskal Algorithm we have number of edges and number of vertices on a given graph but on each edge we have some value or weight on behalf of which we can prepare a new graph which must be not cyclic or not close from any side For Example

graph like this _____________ | | | | | | |__________| | Give name to any vertex a,b,c,d,e,f .

A temporary table can have 3 kinds, the # is the most used. This is a temp table that only exists in the current session. An equivalent of this is @, a declared table variable. This has a little less "functions" (like indexes etc) and is also only used for the current session. The ## is one that is the same as the #, however, the scope is wider, so you can use it within the same session, within other stored procedures.

You can create a temp table in various ways:

declare @table table (id int)
create table #table (id int)
create table ##table (id int)
select * into #table from xyz

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

There is also another method to check Internet connection using the iPhone SDK.

Try to implement the following code for the network connection.

#import <SystemConfiguration/SystemConfiguration.h>
#include <netdb.h>

/**
     Checking for network availability. It returns
     YES if the network is available.
*/
+ (BOOL) connectedToNetwork
{

    // Create zero addy
    struct sockaddr_in zeroAddress;
    bzero(&zeroAddress, sizeof(zeroAddress));
    zeroAddress.sin_len = sizeof(zeroAddress);
    zeroAddress.sin_family = AF_INET;

    // Recover reachability flags
    SCNetworkReachabilityRef defaultRouteReachability =
        SCNetworkReachabilityCreateWithAddress(NULL, (struct sockaddr *)&zeroAddress);
    SCNetworkReachabilityFlags flags;

    BOOL didRetrieveFlags = SCNetworkReachabilityGetFlags(defaultRouteReachability, &flags);
    CFRelease(defaultRouteReachability);

    if (!didRetrieveFlags)
    {
        printf("Error. Could not recover network reachability flags\n");
        return NO;
    }

    BOOL isReachable = ((flags & kSCNetworkFlagsReachable) != 0);
    BOOL needsConnection = ((flags & kSCNetworkFlagsConnectionRequired) != 0);

    return (isReachable && !needsConnection) ? YES : NO;
}

I had a very strange bug. Apparently my launch image source was only set for debug configuration and not release. This resulted in my launch screen appearing when running debug configuration, but when I changed to release I just got a black screen.

I fixed this when I changed my build configuration to release the Launch Image Source button appeared and I had to choose Use Asset Catalog again.

For those who are curious, this is what my project.pbxproj looked like.

...
...
...
XXXXXXXXXXXXXXXXXXXXXXXX /* Release */ = {
            isa = XCBuildConfiguration;
            buildSettings = {
                ALWAYS_SEARCH_USER_PATHS = NO;
                ASSETCATALOG_COMPILER_APPICON_NAME = AppIcon;
                ASSETCATALOG_COMPILER_LAUNCHIMAGE_NAME = LaunchImage; <---THIS LINE WAS MISSING

Make sure the scp command is available on both sides - both on the client and on the server.

If this is Fedora or Red Hat Enterprise Linux and clones (CentOS), make sure this package is installed:

    yum -y install openssh-clients

If you work with Debian or Ubuntu and clones, install this package:

    apt-get install openssh-client

Again, you need to do this both on the server and the client, otherwise you can encounter "weird" error messages on your client: scp: command not found or similar although you have it locally. This already confused thousands of people, I guess :)

As Alex noted you can use jQuery offset() to get the position relative to the document flow. Use position() for its x,y coordinates relative to the parent.

EDIT: Switched document.ready for window.load because load waits for all of the elements so you get their size instead of simply preparing the DOM. In my experience, load results in fewer incorrectly Javascript positioned elements.

$(window).load(function(){ 
  // Log the position with jQuery
  var position = $('#myDivInQuestion').position();
  console.log('X: ' + position.left + ", Y: " + position.top );
});

In my notepad++ I press

Ctrl+A = To select all words

Ctrl+U = To convert lowercase

Ctrl+Shift+U = To convert uppercase

Hope to help you!

There's another solution for it if you are not using native Promises but Bluebird.

You could also try using Promise.map(), mixing the array.map and Promise.all

In you case:

  var arr = [1,2,3,4,5];

  var results: number[] = await Promise.map(arr, async (item): Promise<number> => {
    await callAsynchronousOperation(item);
    return item + 1;
  });

Most UNIX-like operating systems have a basename executable for a very similar purpose (and dirname for the path):

pax> a=/tmp/file.txt
pax> b=$(basename $a)
pax> echo $b
file.txt

That unfortunately just gives you the file name, including the extension, so you'd need to find a way to strip that off as well.

So, given you have to do that anyway, you may as well find a method that can strip off the path and the extension.

One way to do that (and this is a bash-only solution, needing no other executables):

pax> a=/tmp/xx/file.tar.gz
pax> xpath=${a%/*} 
pax> xbase=${a##*/}
pax> xfext=${xbase##*.}
pax> xpref=${xbase%.*}
pax> echo;echo path=${xpath};echo pref=${xpref};echo ext=${xfext}

path=/tmp/xx
pref=file.tar
ext=gz

That little snippet sets xpath (the file path), xpref (the file prefix, what you were specifically asking for) and xfext (the file extension).

On Postgres @Lob is breaking for byte[] as it tries to save it as oid, and for String also same problem occurs. Below code is breaking on postgres which is working fine on oracle.

@Lob
private String stringField;

and

@Lob
private byte[]   someByteStream;

In order to fix above on postgres have written below custom hibernate.dialect

public class PostgreSQLDialectCustom extends PostgreSQL82Dialect{

public PostgreSQLDialectCustom()
{
    super();
    registerColumnType(Types.BLOB, "bytea");
}

 @Override
 public SqlTypeDescriptor remapSqlTypeDescriptor(SqlTypeDescriptor sqlTypeDescriptor) {
    if (Types.CLOB == sqlTypeDescriptor.getSqlType()) {
      return LongVarcharTypeDescriptor.INSTANCE;
    }
    return super.remapSqlTypeDescriptor(sqlTypeDescriptor);
  }
}

Now configure custom dialect in hibernate

hibernate.dialect=X.Y.Z.PostgreSQLDialectCustom   

X.Y.Z is package name.

Now it working fine. NOTE- My Hibernate version - 5.2.8.Final Postgres version- 9.6.3

You can check your Network (console) and See the answer from the Server ... The "<" will be the first letter of your response. Something like "<"undefined index XY in line Z>"

This is what you need to add to make it work.

response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Allow-Methods", "GET,HEAD,OPTIONS,POST,PUT");
response.setHeader("Access-Control-Allow-Headers", "Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers");

The browser sends a preflight request (with method type OPTIONS) to check if the service hosted on the server is allowed to be accessed from the browser on a different domain. In response to the preflight request if you inject above headers the browser understands that it is ok to make further calls and i will get a valid response to my actual GET/POST call. you can constraint the domain to which access is granted by using Access-Control-Allow-Origin", "localhost, xvz.com" instead of * . ( * will grant access to all domains)

Another option would be:

SELECT * FROM [Village] WHERE PATINDEX('foo', [CastleType]) <> 0

Question has a good pagerank on google, so for anyone who's looking for answer to this question this might be helpful.

There is an extension in google chrome marketspace to do exactly that: https://chrome.google.com/webstore/detail/hccmhjmmfdfncbfpogafcbpaebclgjcp

This is not memory address This is classname@hashcode
Which is the default implementation of Object.toString()

public String toString() {
    return getClass().getName() + "@" + Integer.toHexString(hashCode());
}

where

Class name = full qualified name or absolute name (ie package name followed by class name) hashcode = hexadecimal format (System.identityHashCode(obj) or obj.hashCode() will give you hashcode in decimal format).

Hint:
The confusion root cause is that the default implementation of Object.hashCode() use the internal address of the object into an integer

This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.

And of course, some classes can override both default implementations either for toString() or hashCode()

If you need the default implementation value of hashcode() for a object which overriding it,
You can use the following method System.identityHashCode(Object x)

You have to put this as root:

GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'IP' IDENTIFIED BY 'PASSWORD' with grant option;

;

where IP is the IP you want to allow access, USERNAME is the user you use to connect, and PASSWORD is the relevant password.

If you want to allow access from any IP just put % instead of your IP

and then you only have to put

FLUSH PRIVILEGES;

Or restart mysql server and that's it.

The simplest way to create a manifest is:

Project Properties -> Security -> Click "enable ClickOnce security settings" 
(it will generate default manifest in your project Properties) -> then Click 
it again in order to uncheck that Checkbox -> open your app.maifest and edit 
it as you wish.

Also, can be done using "stringr" library:

> library(stringr)
> chars <- "test"
> value <- "es"
> str_detect(chars, value)
[1] TRUE

### For multiple value case:
> value <- c("es", "l", "est", "a", "test")
> str_detect(chars, value)
[1]  TRUE FALSE  TRUE FALSE  TRUE

The extensions methods also provide a ToDictionary extension. It is fairly simple to use, the general usage is passing a lambda selector for the key and getting the object as the value, but you can pass a lambda selector for both key and value.

class SomeObject
{
    public int ID { get; set; }
    public string Name { get; set; }
}

SomeObject[] objects = new SomeObject[]
{
    new SomeObject { ID = 1, Name = "Hello" },
    new SomeObject { ID = 2, Name = "World" }
};

Dictionary<int, string> objectDictionary = objects.ToDictionary(o => o.ID, o => o.Name);

Then objectDictionary[1] Would contain the value "Hello"

Recent progress

March 2014: Good news! Python 3.4 ships with Pip. Pip has long been Python's de-facto standard package manager. You can install a package like this:

pip install httpie

Wahey! This is the best feature of any Python release. It makes the community's wealth of libraries accessible to everyone. Newbies are no longer excluded from using community libraries by the prohibitive difficulty of setup.

However, there remains a number of outstanding frustrations with the Python packaging experience. Cumulatively, they make Python very unwelcoming for newbies. Also, the long history of neglect (ie. not shipping with a package manager for 14 years from Python 2.0 to Python 3.3) did damage to the community. I describe both below.

Outstanding frustrations

It's important to understand that while experienced users are able to work around these frustrations, they are significant barriers to people new to Python. In fact, the difficulty and general user-unfriendliness is likely to deter many of them.

PyPI website is counter-helpful

Every language with a package manager has an official (or quasi-official) repository for the community to download and publish packages. Python has the Python Package Index, PyPI. https://pypi.python.org/pypi

Let's compare its pages with those of RubyGems and Npm (the Node package manager).

1. https://rubygems.org/gems/rails RubyGems page for the package rails
2. https://www.npmjs.org/package/express Npm page for the package express
3. https://pypi.python.org/pypi/simplejson/ PyPI page for the package simplejson

You'll see the RubyGems and Npm pages both begin with a one-line description of the package, then large friendly instructions how to install it.

Meanwhile, woe to any hapless Python user who naively browses to PyPI. On https://pypi.python.org/pypi/simplejson/ , they'll find no such helpful instructions. There is however, a large green 'Download' link. It's not unreasonable to follow it. Aha, they click! Their browser downloads a .tar.gz file. Many Windows users can't even open it, but if they persevere they may eventually extract it, then run setup.py and eventually with the help of Google setup.py install. Some will give up and reinvent the wheel..

Of course, all of this is wrong. The easiest way to install a package is with a Pip command. But PyPI didn't even mention Pip. Instead, it led them down an archaic and tedious path.

Error: Unable to find vcvarsall.bat

Numpy is one of Python's most popular libraries. Try to install it with Pip, you get this cryptic error message:

Error: Unable to find vcvarsall.bat

Trying to fix that is one of the most popular questions on Stack Overflow: "error: Unable to find vcvarsall.bat"

Few people succeed.

For comparison, in the same situation, Ruby prints this message, which explains what's going on and how to fix it:

Please update your PATH to include build tools or download the DevKit from http://rubyinstaller.org/downloads and follow the instructions at http://github.com/oneclick/rubyinstaller/wiki/Development-Kit

Publishing packages is hard

Ruby and Nodejs ship with full-featured package managers, Gem (since 2007) and Npm (since 2011), and have nurtured sharing communities centred around GitHub. Npm makes publishing packages as easy as installing them, it already has 64k packages. RubyGems lists 72k packages. The venerable Python package index lists only 41k.

History

Flying in the face of its "batteries included" motto, Python shipped without a package manager until 2014.

Until Pip, the de facto standard was a command easy_install. It was woefully inadequate. The was no command to uninstall packages.

Pip was a massive improvement. It had most the features of Ruby's Gem. Unfortunately, Pip was--until recently--ironically difficult to install. In fact, the problem remains a top Python question on Stack Overflow: "How do I install pip on Windows?"

your answer is throwing errors because of this line

readings = int(readings)

1. Here you are trying to convert a string into int type which is not base-10. you can convert a string into int only if it is base-10 otherwise it will throw ValueError, stating invalid literal for int() with base 10.

I think that you had intialized a 3d array but you are trying to access an array with 4 dimension.

1. From What's this "serialization" thing all about?:

   It lets you take an object or group of objects, put them on a disk or send them through a wire or wireless transport mechanism, then later, perhaps on another computer, reverse the process: resurrect the original object(s). The basic mechanisms are to flatten object(s) into a one-dimensional stream of bits, and to turn that stream of bits back into the original object(s).

   Like the Transporter on Star Trek, it's all about taking something complicated and turning it into a flat sequence of 1s and 0s, then taking that sequence of 1s and 0s (possibly at another place, possibly at another time) and reconstructing the original complicated "something."

   So, implement the Serializable interface when you need to store a copy of the object, send them to another process which runs on the same system or over the network.

2. Because you want to store or send an object.

3. It makes storing and sending objects easy. It has nothing to do with security.

This worked for me

In JSP, to view the image

<img src="${pageContext.request.contextPath}/resources/images/slide-are.jpg">

In dispatcher-servlet.xml

<mvc:annotation-driven />
<mvc:resources mapping="/resources/**" location="/WEB-INF/resources/" />

It looks like you just want:

eventCustom.DateTimeEnd = string.IsNullOrWhiteSpace(dateTimeEnd)
    ? (DateTime?) null
    : DateTime.Parse(dateTimeEnd);

Note that this will throw an exception if dateTimeEnd isn't a valid date.

An alternative would be:

DateTime validValue;
eventCustom.DateTimeEnd = DateTime.TryParse(dateTimeEnd, out validValue)
    ? validValue
    : (DateTime?) null;

That will now set the result to null if dateTimeEnd isn't valid. Note that TryParse handles null as an input with no problems.

Or you can use

<select [(ngModel)]="Answers[''+question.Name+'']" ng-options="option for option in question.Options">
        </select>

Following is the DP based solution for Edit Distance problem which is top down. I hope it will also help in understanding the world of Dynamic Programming:

public int minDistance(String word1, String word2) {//Standard dynamic programming puzzle.
         int m = word2.length();
            int n = word1.length();


     if(m == 0) // Cannot miss the corner cases !
                return n;
        if(n == 0)
            return m;
        int[][] DP = new int[n + 1][m + 1];

        for(int j =1 ; j <= m; j++) {
            DP[0][j] = j;
        }
        for(int i =1 ; i <= n; i++) {
            DP[i][0] = i;
        }

        for(int i =1 ; i <= n; i++) {
            for(int j =1 ; j <= m; j++) {
                if(word1.charAt(i - 1) == word2.charAt(j - 1))
                    DP[i][j] = DP[i-1][j-1];
                else
                DP[i][j] = Math.min(Math.min(DP[i-1][j], DP[i][j-1]), DP[i-1][j-1]) + 1; // Main idea is this.
            }
        }

        return DP[n][m];
}

You can think of its recursive implementation at your home. It's quite good and challenging if you haven't solved something like this before.

If you renamed the folder containing your Homestead project, you'll get this error. Visit your Homestead.yaml file and update any references to point to the renamed folder, then do vagrant up (etc.) again

I'd use something like:

dim customer = (from c in xmldoc...<Customer> 
                where c.<ID>.Value=22 
                select c).SingleOrDefault 

Edit:

missed the c# tag, sorry......the example is in VB.NET

In the case of some programs, these errors are normal and should not be fixed.

I get these error messages when compiling the program phrap (for example). This program happens to contain code that modifies or replaces some built in functions, and when I include the appropriate header files to fix the warnings, GCC instead generates a bunch of errors. So fixing the warnings effectively breaks the build.

If you got the source as part of a distribution that should compile normally, the errors might be normal. Consult the documentation to be sure.

Below you have some VALID html5 example document. The type attribute in script tag is not mandatory in HTML5.

You use jquery by $ charater. Put libraries (like jquery) in <head> tag - but your script put allways at the bottom of document (<body> tag) - due this you will be sure that all libraries and html document will be loaded when your script execution starts. You can also use src attribute in bottom script tag to include you script file instead of putting direct js code like above.

<!doctype html>_x000D_
<html lang="en">_x000D_
<head>_x000D_
    <meta charset="utf-8">_x000D_
    <title>Example</title>_x000D_

In Laravel 5 simply:

$table->timestamps(); //Adds created_at and updated_at columns.

Documentation: http://laravel.com/docs/5.1/migrations#creating-columns

For php 5.3+ you can use the SplFileInfo() class

$spl = new SplFileInfo($filename); 
print_r($spl->getExtension()); //gives extension 

Also since you are checking extension for file uploads, I highly recommend using the mime type instead..

For php 5.3+ use the finfo class

$finfo = new finfo(FILEINFO_MIME);
print_r($finfo->buffer(file_get_contents($file name)); 

jQuery-CSV

It's a jQuery plugin designed to work as an end-to-end solution for parsing CSV into JavaScript data. It handles every single edge case presented in RFC 4180, as well as some that pop up for Excel/Google spreadsheet exports (i.e., mostly involving null values) that the specification is missing.

Example:

track,artist,album,year

Dangerous,'Busta Rhymes','When Disaster Strikes',1997

// Calling this
music = $.csv.toArrays(csv)

// Outputs...
[
  ["track", "artist", "album", "year"],
  ["Dangerous", "Busta Rhymes", "When Disaster Strikes", "1997"]
]

console.log(music[1][2]) // Outputs: 'When Disaster Strikes'

Update:

Oh yeah, I should also probably mention that it's completely configurable.

music = $.csv.toArrays(csv, {
  delimiter: "'", // Sets a custom value delimiter character
  separator: ';', // Sets a custom field separator character
});

Update 2:

It now works with jQuery on Node.js too. So you have the option of doing either client-side or server-side parsing with the same library.

Update 3:

Since the Google Code shutdown, jquery-csv has been migrated to GitHub.

Disclaimer: I am also the author of jQuery-CSV.

what is the exec function and its family.

The exec function family is all functions used to execute a file, such as execl, execlp, execle, execv, and execvp.They are all frontends for execve and provide different methods of calling it.

why is this function used

Exec functions are used when you want to execute (launch) a file (program).

and how does it work.

They work by overwriting the current process image with the one that you launched. They replace (by ending) the currently running process (the one that called the exec command) with the new process that has launched.

For more details: see this link.

Install this nuget package from Microsoft System.Net.Http.Json. It contains extension methods.

Then add using System.Net.Http.Json

Now, you'll be able to see these methods:

So you can now do this:

await httpClient.GetFromJsonAsync<IList<WeatherForecast>>("weatherforecast");

Typical code is to create an explicit method to add to the list, and create the ArrayList on the fly when adding. Note the synchronization so the list only gets created once!

@Override
public synchronized boolean addToList(String key, Item item) {
   Collection<Item> list = theMap.get(key);
   if (list == null)  {
      list = new ArrayList<Item>();  // or, if you prefer, some other List, a Set, etc...
      theMap.put(key, list );
   }

   return list.add(item);
}

The best way is to use simple math

>>> a = 8
>>> a**(1./3.)
2.0

EDIT

For Negative numbers

>>> a = -8
>>> -(-a)**(1./3.)
-2.0

Complete Program for all the requirements as specified

x = int(input("Enter an integer: "))
if x>0:
    ans = x**(1./3.)
    if ans ** 3 != abs(x):
        print x, 'is not a perfect cube!'
else:
    ans = -((-x)**(1./3.))
    if ans ** 3 != -abs(x):
        print x, 'is not a perfect cube!'

print 'Cube root of ' + str(x) + ' is ' + str(ans)

A solution with Gson:

Gson gson = new Gson();
JsonElement jsonElement = gson.toJsonTree(map);
MyPojo pojo = gson.fromJson(jsonElement, MyPojo.class);

If you are really worried about undefined being redefined, you can protect against this with some helper method like this:

function is_undefined(value) {
   var undefined_check; // instantiate a new variable which gets initialized to the real undefined value
   return value === undefined_check;
}

This works because when someone writes undefined = "foo" he only lets the name undefined reference to a new value, but he doesn't change the actual value of undefined.

In pandas, is inplace = True considered harmful, or not?

TLDR; Yes, yes it is.

• inplace, contrary to what the name implies, often does not prevent copies from being created, and (almost) never offers any performance benefits
• inplace does not work with method chaining
• inplace can lead to SettingWithCopyWarning if used on a DataFrame column, and may prevent the operation from going though, leading to hard-to-debug errors in code

The pain points above are common pitfalls for beginners, so removing this option will simplify the API.

I don't advise setting this parameter as it serves little purpose. See this GitHub issue which proposes the inplace argument be deprecated api-wide.

It is a common misconception that using inplace=True will lead to more efficient or optimized code. In reality, there are absolutely no performance benefits to using inplace=True. Both the in-place and out-of-place versions create a copy of the data anyway, with the in-place version automatically assigning the copy back.

inplace=True is a common pitfall for beginners. For example, it can trigger the SettingWithCopyWarning:

df = pd.DataFrame({'a': [3, 2, 1], 'b': ['x', 'y', 'z']})

df2 = df[df['a'] > 1]
df2['b'].replace({'x': 'abc'}, inplace=True)
# SettingWithCopyWarning: 
# A value is trying to be set on a copy of a slice from a DataFrame

Calling a function on a DataFrame column with inplace=True may or may not work. This is especially true when chained indexing is involved.

As if the problems described above aren't enough, inplace=True also hinders method chaining. Contrast the working of

result = df.some_function1().reset_index().some_function2()

As opposed to

temp = df.some_function1()
temp.reset_index(inplace=True)
result = temp.some_function2()

The former lends itself to better code organization and readability.

Another supporting claim is that the API for set_axis was recently changed such that inplace default value was switched from True to False. See GH27600. Great job devs!

An alternative using envsubst without losing the ability to use commands like COPY or ADD, and without using intermediate files would be to use Bash's Process Substitution:

docker build -f <(envsubst < Dockerfile) -t my-target .

I'm using a very minimal busybox system, in which there is no support for ranges in tr or POSIX character classes, so I have to do it the crappy old-fashioned way. Here's the solution with sed, stripping ALL non-printable non-ASCII characters from the file:

sed -i 's/[^a-zA-Z 0-9`~!@#$%^&*()_+\[\]\\{}|;'\'':",.\/<>?]//g' FILE

Try this

Flot

Limitations: lines, points, filled areas, bars, pie and combinations of these

From an interaction perspective, Flot by far will get you as close as possible to Flash graphing as you can get with jQuery. Whilst the graph output is pretty slick, and great looking, you can also interact with data points. What I mean by this is you can have the ability to hover over a data point and get visual feedback on the value of that point in the graph.

The trunk version of flot supports pie charts.

Flot Zoom capability.

On top of this, you also have the ability to select a chunk of the graph to get data back for a particular “zone”. As a secondary feature to this “zoning”, you can also select an area on a graph and zoom in to see the data points a little more closely. Very cool.

Sparklines

Limitations: Pie, Line, Bar, Combination

Sparklines is my favourite mini graphing tool out there. Really great for dashboard style graphs (think Google Analytics dashboard next time you login). Because they’re so tiny, they can be included in line (as in the example above). Another nice idea which can be used in all graphing plugins is the self-refresh capabilities. Their Mouse-Speed demo shows you the power of live charting at its best.

Query Chart 0.21

Limitations: Area, Line, Bar and combinations of these

jQuery Chart 0.21 isn’t the nicest looking charting plugin out there it has to be said. It’s pretty basic in functionality when it comes to the charts it can handle, however it can be flexible if you can put in some time and effort into it.

Adding values into a chart is relatively simple:

.chartAdd({

    "label"  : "Leads",
    "type"   : "Line",
    "color"  : "#008800",
    "values" : ["100","124","222","44","123","23","99"]
});

jQchart

Limitations: Bar, Line

jQchart is an odd one, they’ve built in animation transistions and drag/drop functionality into the chart, however it’s a little clunky – and seemingly pointless. It does generate nice looking charts if you get the CSS setup right, but there are better out there.

TufteGraph

Limitations: Bar and Stacked Bar

Tuftegraph sells itself as “pretty bar graphs that you would show your mother”. It comes close, Flot is prettier, but Tufte does lend itself to be very lightweight. Although with that comes restrictions – there are few options to choose from, so you get what you’re given. Check it out for a quick win bar chart.

    // Create two collections:
    LinkedList<String> listA =  new LinkedList<String>();
    ArrayList<String> listB =  new ArrayList<String>();

    // Add some elements to listA:
    listA.add("A");
    listA.add("B");
    listA.add("C");
    listA.add("D");

    // Add some elements to listB:
    listB.add("A");
    listB.add("B");
    listB.add("C");

    // use 

    List<String> common = new ArrayList<String>(listA);
    // use common.retainAll

    common.retainAll(listB);

    System.out.println("The common collection is : " + common);

To have an idea of the speed penalty, I have tested two versions, one with Array.fill and one with StringBuilder.

public static String repeat(char what, int howmany) {
    char[] chars = new char[howmany];
    Arrays.fill(chars, what);
    return new String(chars);
}

and

public static String repeatSB(char what, int howmany) {
    StringBuilder out = new StringBuilder(howmany);
    for (int i = 0; i < howmany; i++)
        out.append(what);
    return out.toString();
}

using

public static void main(String... args) {
    String res;
    long time;

    for (int j = 0; j < 1000; j++) {
        res = repeat(' ', 100000);
        res = repeatSB(' ', 100000);
    }
    time = System.nanoTime();
    res = repeat(' ', 100000);
    time = System.nanoTime() - time;
    System.out.println("elapsed repeat: " + time);

    time = System.nanoTime();
    res = repeatSB(' ', 100000);
    time = System.nanoTime() - time;
    System.out.println("elapsed repeatSB: " + time);
}

(note the loop in main function is to kick in JIT)

The results are as follows:

elapsed repeat: 65899
elapsed repeatSB: 305171

It is a huge difference

You need to make sure, when you run command (install npm -g gulp), it will create install gulp on C:\ directory.

that directory should match with whatver npm path variable set in your java path.

just run path from command prompt, and verify this. if not, change your java class path variable wherever you gulp is instaled.

It should work.

Convert without creating String object:

import java.nio.CharBuffer;
import java.nio.ByteBuffer;
import java.util.Arrays;

byte[] toBytes(char[] chars) {
  CharBuffer charBuffer = CharBuffer.wrap(chars);
  ByteBuffer byteBuffer = Charset.forName("UTF-8").encode(charBuffer);
  byte[] bytes = Arrays.copyOfRange(byteBuffer.array(),
            byteBuffer.position(), byteBuffer.limit());
  Arrays.fill(byteBuffer.array(), (byte) 0); // clear sensitive data
  return bytes;
}

Usage:

char[] chars = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};
byte[] bytes = toBytes(chars);
/* do something with chars/bytes */
Arrays.fill(chars, '\u0000'); // clear sensitive data
Arrays.fill(bytes, (byte) 0); // clear sensitive data

Solution is inspired from Swing recommendation to store passwords in char[]. (See Why is char[] preferred over String for passwords?)

Remember not to write sensitive data to logs and ensure that JVM won't hold any references to it.

The code above is correct but not effective. If you don't need performance but want security you can use it. If security also not a goal then do simply String.getBytes. Code above is not effective if you look down of implementation of encode in JDK. Besides you need to copy arrays and create buffers. Another way to convert is inline all code behind encode (example for UTF-8):

val xs: Array[Char] = "A ß € ?  ".toArray
val len = xs.length
val ys: Array[Byte] = new Array(3 * len) // worst case
var i = 0; var j = 0 // i for chars; j for bytes
while (i < len) { // fill ys with bytes
  val c = xs(i)
  if (c < 0x80) {
    ys(j) = c.toByte
    i = i + 1
    j = j + 1
  } else if (c < 0x800) {
    ys(j) = (0xc0 | (c >> 6)).toByte
    ys(j + 1) = (0x80 | (c & 0x3f)).toByte
    i = i + 1
    j = j + 2
  } else if (Character.isHighSurrogate(c)) {
    if (len - i < 2) throw new Exception("overflow")
    val d = xs(i + 1)
    val uc: Int = 
      if (Character.isLowSurrogate(d)) {
        Character.toCodePoint(c, d)
      } else {
        throw new Exception("malformed")
      }
    ys(j) = (0xf0 | ((uc >> 18))).toByte
    ys(j + 1) = (0x80 | ((uc >> 12) & 0x3f)).toByte
    ys(j + 2) = (0x80 | ((uc >>  6) & 0x3f)).toByte
    ys(j + 3) = (0x80 | (uc & 0x3f)).toByte
    i = i + 2 // 2 chars
    j = j + 4
  } else if (Character.isLowSurrogate(c)) {
    throw new Exception("malformed")
  } else {
    ys(j) = (0xe0 | (c >> 12)).toByte
    ys(j + 1) = (0x80 | ((c >> 6) & 0x3f)).toByte
    ys(j + 2) = (0x80 | (c & 0x3f)).toByte
    i = i + 1
    j = j + 3
  }
}
// check
println(new String(ys, 0, j, "UTF-8"))

Excuse me for using Scala language. If you have problems with converting this code to Java I can rewrite it. What about performance always check on real data (with JMH for example). This code looks very similar to what you can see in JDK[2] and Protobuf[3].

For windows

;extension=php_mcrypt.dll to extension=php_mcrypt.dll 
 then restart your apache server

For Redhat

sudo yum install php55-mcrypt //if php5.5
sudo yum install php-mcrypt //if less than 5.4
sudo service httpd restart //if apache 2.4
sudo /etc/init.d/httpd restart //if apache 2.2 or less

For Ubuntu

sudo apt-get install php5-mcrypt
sudo service apache2 restart //if server not reloaded automatically 

Still not working?

sudo php5enmod mcrypt && sudo service apache2 restart

I will provide a simple and general answer that works with any number of audios and srt subtitles and respects the metadata that may include the mkv container. So it will even add the images the matroska may include as attachments (though not another types AFAIK) and convert them to tracks; you will not be able to watch but they will be there (you can demux them). Ah, and if the mkv has chapters the mp4 too.

ffmpeg -i <mkv-input> -c copy -map 0 -c:s mov_text <mp4-output>

As you can see, it's all about the -map 0, that tells FFmpeg to add all the tracks, which includes metadata, chapters, attachments, etc. If there is an unrecognized "track" (mkv allows to attach any type of file), it will end with an error.

You can create a simple batch mkv2mp4.bat, if you usually do this, to create an mp4 with the same name as the mkv. It would be better with error control, a different output name, etc., but you get the point.

@ffmpeg -i %1 -c copy -map 0 -c:s mov_text "%~n1.mp4"

Now you can simply run

mkv2mp4 "Video with subtitles etc.mkv"

And it will create "Video with subtitles etc.mp4" with the maximum of information included.

The important thing about a sprint is that: within a sprint the functionality that is to be delivered is fixed.

A sprint is normally an iteration. But you can for example have a 4 week sprint, but have 4 one week "internal" iterations within that sprint.

There is a lot of discussion about the length of sprints. I think that if you do it according to the book they should all be the same length.

We have found that a short first sprint to get the development environment up and running, followed by longer basic functionality sprints, then short sprints towards the end of the project, has worked for us.

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

Setting isBodyHtml to true allows you to use HTML tags in the message body:

msg = new MailMessage("[email protected]",
                "[email protected]", "Message from PSSP System",
                "This email sent by the PSSP system<br />" +
                "<b>this is bold text!</b>");

msg.IsBodyHtml = true;

I believe you might be missing a "Grant Connect To" statement when you created the database user.

Below is the complete snippet you will need to create both a login against the SQL Server DBMS as well as a user against the database

USE [master]
GO

CREATE LOGIN [SqlServerLogin] WITH PASSWORD=N'Passwordxyz', DEFAULT_DATABASE=[master], CHECK_EXPIRATION=OFF, CHECK_POLICY=ON
GO

USE [myDatabase]
GO

CREATE USER [DatabaseUser] FOR LOGIN [SqlServerLogin] WITH DEFAULT_SCHEMA=[mySchema]
GO

GRANT CONNECT TO [DatabaseUser]
GO

-- the role membership below will allow you to run a test "select" query against the tables in your database
ALTER ROLE [db_datareader] ADD MEMBER [DatabaseUser]

Here's what I had to do to setup basic auth on Ubuntu 14.04 (didn't find a guide anywhere else)

Basic squid conf

/etc/squid3/squid.conf instead of the super bloated default config file

auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

# Choose the port you want. Below we set it to default 3128.
http_port 3128

Please note the basic_ncsa_auth program instead of the old ncsa_auth

squid 2.x

For squid 2.x you need to edit /etc/squid/squid.conf file and place:

auth_param basic program /usr/lib/squid/digest_pw_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Setting up a user

sudo htpasswd -c /etc/squid3/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid3 restart

squid 2.x

sudo htpasswd -c /etc/squid/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid restart

htdigest vs htpasswd

For the many people that asked me: the 2 tools produce different file formats:

• htdigest stores the password in plain text.
• htpasswd stores the password hashed (various hashing algos are available)

Despite this difference in format basic_ncsa_auth will still be able to parse a password file generated with htdigest. Hence you can alternatively use:

sudo htdigest -c /etc/squid3/passwords realm_you_like username_you_like

Beware that this approach is empirical, undocumented and may not be supported by future versions of Squid.

On Ubuntu 14.04 htdigest and htpasswd are both available in the [apache2-utils][1] package.

MacOS

Similar as above applies, but file paths are different.

Install squid

brew install squid

Start squid service

brew services start squid

Squid config file is stored at /usr/local/etc/squid.conf.

Comment or remove following line:

http_access allow localnet

Then similar to linux config (but with updated paths) add this:

auth_param basic program /usr/local/Cellar/squid/4.8/libexec/basic_ncsa_auth /usr/local/etc/squid_passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Note that path to basic_ncsa_auth may be different since it depends on installed version when using brew, you can verify this with ls /usr/local/Cellar/squid/. Also note that you should add the above just bellow the following section:

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

Now generate yourself a user:password basic auth credential (note: htpasswd and htdigest are also both available on MacOS)

htpasswd -c /usr/local/etc/squid_passwords username_you_like

Restart the squid service

brew services restart squid

You seem to look for the input attribute value, "the initial value of the control"?

<input type="text" value="Morlodenhof 7" />

https://developer.mozilla.org/de/docs/Web/HTML/Element/Input#attr-value

Remove Object from NSArray with this Method:

-(NSArray *) removeObjectFromArray:(NSArray *) array withIndex:(NSInteger) index {
    NSMutableArray *modifyableArray = [[NSMutableArray alloc] initWithArray:array];
    [modifyableArray removeObjectAtIndex:index];
    return [[NSArray alloc] initWithArray:modifyableArray];
}

I'm not an expert on this, but I can try and contribute a few answers:

1. NetHack and it's brethern are open source and rely heavily on procedural generation of levels (maps). Link to the downloads of it. If you are more interested in landscape/texture/cloud generation, I'd recommend you search Gamasutra and GameDev which have quite a few articles on those subjects.

2. AFAIK I don't think there is much difference between languages. Most of the code you see will be in C/CPP because it's still very much the official language of Game Developers, but you can use anything you want...

3. Well it depends if you have a project that can benefit from such technology. I saw procedural generation used in simulators for the army (which can be considered a game, although they are not very playable :)).

And a small note - my definition if procedural generation is anything generating a lot of data from a small amount of rules or patterns and lots of randomness, your results may vary :)

You can submit any form automatically on page load simply by adding a snippet of javascript code to your body tag referencing the form name like this....

<body onload="document.form1.submit()">

For newbies like me, who end up on this question: This error also happens if you attempt to call .select2() on an element retrieved using pure javascript and not using jQuery.

This fails with the "select2 is not a function" error:

document.getElementById('e9').select2();

This works:

$("#e9").select2();

How about...

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy"];

//Optionally for time zone conversions
[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"..."]];

NSString *stringFromDate = [formatter stringFromDate:myNSDateInstance];

//unless ARC is active
[formatter release];

Swift 4.2 :

func stringFromDate(_ date: Date) -> String {
    let formatter = DateFormatter()
    formatter.dateFormat = "dd MMM yyyy HH:mm" //yyyy
    return formatter.string(from: date)
}

I would say the server is running out of physical/swap memory, so PHP can't allocate enough memory.

Can you paste the output of free here?

    for (Direction  d : Direction.values()) {
       //your code here   
    }

An easy fix to this question is to add '[' in the start of your json file, and ending it with a ']'. This solved it for me.

I tried this tool and it gave me good results.

https://github.com/major/MySQLTuner-perl

don't they both keep a value for another request?

Yes they do, but when the first one is void, the second one returns and object:

public void Keep(string key)
{
    _retainedKeys.Add(key); // just adds the key to the collection for retention
}

public object Peek(string key)
{
    object value;
    _data.TryGetValue(key, out value);
    return value; // returns an object without marking it for deletion
}

string.Split() returns an array - you can convert it to a list using ToList():

listStrLineElements = line.Split(',').ToList();

Note that you need to import System.Linq to access the .ToList() function.

None of the suggestions above worked for me. The following did!

HttpContext.Current.Request.LogonUserIdentity.Name

I guess there's a wide variety of scenarios and this one worked for me. My scenario involved an AngularJS frontend and a Web API 2 backend application, both running under IIS. I had to set both applications to run exclusively under Windows Authentication.

No need to pass any user information. The browser and IIS exchange the logged on user credentials and the Web API has access to the user credentials on demand (from IIS I presume).

you can use

SELECT [column_name] 
FROM [table_name]
WHERE [column_name] LIKE '% %' 
OR [column_name] IS NULL

So i had the same error :importError bad magic number. This was on windows 10

This error was because i installed mysql-connector

So i had to; pip uninstall mysql-comnector pip uninstall mysql-connector-python

pip install mysql-connector-python

As mentioned in one of the answers you can use the Patterns class as below:

public final static boolean isValidEmail(CharSequence target) {
    if (target == null) 
        return false;

    return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
}

By chance if you are even supporting API level less than 8, then you can simply copy the Patterns.java file into your project and reference it. You can get the source code for Patterns.java from this link

sudo chmod 777 DIR_NAME
cd DIR_NAME
git clone https://github.com/mygitusername/kivy.git

should work fine

If you check Thrown for Common Language Runtime Exception in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.

This will probably give you some insight into what is going on.

The meaning of null=True and blank=True in the model also depends on how these fields were defined in the form class.

Suppose you have defined the following class:

class Client (models.Model):
    name = models.CharField (max_length=100, blank=True)
    address = models.CharField (max_length=100, blank=False)

If the form class has been defined like this:

class ClientForm (ModelForm):
    class Meta:
        model = Client
        fields = ['name', 'address']
        widgets = {
            'name': forms.TextInput (attrs = {'class': 'form-control form-control-sm'}),
            'address': forms.TextInput (attrs = {'class': 'form-control form-control-sm'})
        }

Then, the 'name' field will not be mandatory (due to the blank=True in the model) and the 'address' field will be mandatory (due to the blank=False in the model).

However, if the ClientForm class has been defined like this:

class ClientForm (ModelForm):
    class Meta:
        model = Client
        fields = ['name', 'address']

    name = forms.CharField (
        widget = forms.TextInput (attrs = {'class': 'form-control form-control-sm'}),
    )
    address = forms.CharField (
        widget = forms.TextInput (attrs = {'class': 'form-control form-control-sm'}),
    )

Then, both fields ('name' and 'address') will be mandatory, "since fields defined declaratively are left as-is" (https://docs.djangoproject.com/en/3.0/topics/forms/modelforms/), i.e. the default for the 'required' attribute of the form field is True and this will require that the fields 'name' and 'address' are filled, even if, in the model, the field has been set to blank=True.

$objPHPExcel->getActiveSheet()->getStyle("A1:".$objPHPExcel->getActiveSheet()->getHighestDataColumn()."1")->getFont()->setBold(true);

I found this to be a working solution, you can replace the two instances of 1 with the row number. The HighestDataColumn function returns for example C or Z, it gives you the last/highest column that's in the sheet containing any data. There is also getHighestColumn(), that one would include cells that are empty but have styling or are part of other functionality.

You can use killall command as well .

-o, --older-than Match only processes that are older (started before) the time specified. The time is specified as a float then a unit. The units are s,m,h,d,w,M,y for seconds, minutes, hours, days,

-e, --exact Require an exact match for very long names.

-r, --regexp Interpret process name pattern as an extended regular expression.

This worked like a charm.

The main (very interesting) difference for me is that:
"string" & Null -> "string"
while
"string" + Null -> Null

But that's probably more useful in database apps like Access.

Set an id to the option then use get element by id and disable it when x value has been selected..

example

<body>
      <select class="pull-right text-muted small" 
                 name="driveCapacity" id=driveCapacity onchange="checkRPM()">
      <option value="4000.0" id="4000">4TB</option>
      <option value="900.0" id="900">900GB</option>
      <option value="300.0" id ="300">300GB</option>
    </select>
    </body>
<script>
var perfType = document.getElementById("driveRPM").value;
if(perfType == "7200"){         
        document.getElementById("driveCapacity").value = "4000.0";
        document.getElementById("4000").disabled = false;           
    }else{          
        document.getElementById("4000").disabled = true;            
    }    
</script>

Using the reshape package you can do something like this.

library(ggplot2)
wide <- data.frame(x = rnorm(100), eps = rnorm(100, 0, .2))
wide$first <- with(wide, 3 * x + eps)
wide$second <- with(wide, 2 * x + eps)
long <- melt(wide, id.vars = c("x", "eps"))
ggplot(long, aes(x = x, y = value)) + geom_smooth() + geom_point() + facet_grid(.~ variable)

I had the very same issue running Jupyter. After chasing my tail on permissions, I found that everything cleared up after I changed ownership on the directory where I was trying to run/store my notebooks. Ex.: I was running my files out of my ~/bash dir. That was root:root; when I changed it to jim:jim....no more errors.

Enter super user mode, and cd into the directory that you are not permissioned to go into. Sudo requires administrator password.

sudo su
cd directory

Subset is a very slow function , and I personally find it useless.

I assume you have a data.frame, array, matrix called Mat with A, B, C as column names; then all you need to do is:

• In the case of one condition on one column, lets say column A

  Mat[which(Mat[,'A'] == 10), ]
  

In the case of multiple conditions on different column, you can create a dummy variable. Suppose the conditions are A = 10, B = 5, and C > 2, then we have:

    aux = which(Mat[,'A'] == 10)
    aux = aux[which(Mat[aux,'B'] == 5)]
    aux = aux[which(Mat[aux,'C'] > 2)]
    Mat[aux, ]

By testing the speed advantage with system.time, the which method is 10x faster than the subset method.

I can run on my device at last, just I enabled the "USB debugging" and "Allow mock location" options from the Debug Menu of my device.

You can try using groovy. It runs on the JVM and it comes with great support for running external processes and extracting the output:

http://groovy.codehaus.org/Executing+External+Processes+From+Groovy

You can see in this code taken from the same link how groovy makes it easy to get the status of the process:

println "return code: ${ proc.exitValue()}"
println "stderr: ${proc.err.text}"
println "stdout: ${proc.in.text}" // *out* from the external program is *in* for groovy

If you use Ubuntu or Debian, I made a tutorial easy to follow: Install LaTeX on Ubuntu or Debian. This tutorial explains how to install LaTeX and how to create your first PDF.

The $http legacy promise methods success and error have been deprecated. Use the standard then method instead. Have a look at the docs https://docs.angularjs.org/api/ng/service/$http

Now the right way to use is:

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
});

The response object has these properties:

• data – {string|Object} – The response body transformed with the transform functions.
• status – {number} – HTTP status code of the response.
• headers – {function([headerName])} – Header getter function.
• config – {Object} – The configuration object that was used to generate the request.
• statusText – {string} – HTTP status text of the response.

A response status code between 200 and 299 is considered a success status and will result in the success callback being called.

Sometimes, the minimal installation of Linux in Docker doesn't define the path and therefore it is necessary to call ping using ....

Since answers posted only allow you to query the active network, here's how to get NetworkInfo for any network, not only the active one (for example Wifi network) (sorry, Kotlin code ahead)

(getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager).run {
    allNetworks.find { getNetworkInfo(it).type == ConnectivityManager.TYPE_WIFI }?.let { network -> getNetworkInfo(network) }
//    getNetworkInfo(ConnectivityManager.TYPE_WIFI).isAvailable // This is the deprecated API pre-21
}

This requires API 21 or higher and the permission android.permission.ACCESS_NETWORK_STATE

2 Steps:

Step 1) calculate the ratio of the original width / original height of Image.

Step 2) multiply the original_width/original_height ratio by the new desired height to get the new width corresponding to the new height.

I added the start and exit which works. Without both it was not working

start C:/Anaconda3/Library/bin/pyrcc4.exe -py3 {path}/Resourses.qrc -{path}/Resourses_rc.py
exit

This is what I did in addition to @sagar-gavhane's answer

const newUser = {_id: 4, name: 'Adam'}
const users = [{_id: 1, name: 'Fred'}, {_id: 2, name: 'Ted'}, {_id: 3, name:'Bill'}]

const userExists = users.some(user => user.name === newUser.name);
if(userExists) {
    return new Error({error:'User exists'})
}
users.push(newUser)

Another DISTINCT answer, but with multiple values:

SELECT DISTINCT `field1`, `field2`, `field3` FROM `some_table`  WHERE `some_field` > 5000 ORDER BY `some_field`

You can use this function:

function str_lreplace($search, $replace, $subject)
{
    $pos = strrpos($subject, $search);

    if($pos !== false)
    {
        $subject = substr_replace($subject, $replace, $pos, strlen($search));
    }

    return $subject;
}

Raphael is not supported on pre 3.0 Android browsers, that's what your problem is. They have no support for SVG graphics. It does have support for canvas though. If you don't need to animate it, you could render the graphics with canvg:

http://code.google.com/p/canvg/

That's how we got around this issue for rendering SVG icons in the default Android browser.

I resolved it like this:

<% @user.errors.each do |attr, msg| %>
  <li>
    <%= @user.errors.full_messages_for(attr).first if @user.errors[attr].first == msg %>
  </li>
<% end %>

This way you are using the locales for the error messages.

Alternative to sp_defaultdb (which will be removed in a future version of Microsoft SQL Server) could be ALTER LOGIN:

ALTER LOGIN [my_user_name] WITH DEFAULT_DATABASE = [new_default_database]

Note: unlike the sp_defaultdb solution user and database names are provided without quotes. Brackets are needed if name had special chars (most common example will be domain user which is domain\username and won't work without brackets).

I had the same problem many times. This can be solved by using the basetag npm package. It doesn't have to be required itself, only installed as it creates a symlink inside node_modules to your base path.

const localFile = require('$/local/file')
// instead of
const localFile = require('../../local/file')

Using the $/... prefix will always reference files relative to your apps root directory.

In C# 9 Microsoft will introduce a new way to have properties set only on initialization using the init; method like so:

public class Person
{
  public string firstName { get; init; }
  public string lastName { get; init; }
}

This way, you can assign values when initializing a new object:

var person = new Person
{
  firstname = "John",
  lastName = "Doe"
}

But later on, you cannot change it:

person.lastName = "Denver"; // throws a compiler error

Here's what we do:

• Create a new connection, set the name, IP address and the appropriate port:

  

• Set up authentication, if required

  

• Optionally set up other available settings for SSL, SSH, etc.

• Save and connect

If the image is too large and you can't save&load it to the storage, you should consider just using a global static reference to the bitmap (inside the receiving activity), which will be reset to null on onDestory, only if "isChangingConfigurations" returns true.

I've converted my answer into article so more people can find this useful, MySQL: Datetime Versus Timestamp Data Types.

This is one way without using time a zone:

LocalDateTime now = LocalDateTime.now();
long epoch = (now.getLong(ChronoField.EPOCH_DAY) * 86400000) + now.getLong(ChronoField.MILLI_OF_DAY);

result = initial number + (6 - initial number % 6)

The code I'll give you works and retrieves not only keys, but a lot of data from a table in SQL Server. Is tested in SQL Server 2k5/2k8, dunno about 2k. Enjoy!

}

save

I have build a sample android studio project for this question.

output screen shots :-

Download full project source code Click here

Please note: you have to add your API key in Androidmanifest.xml

>>> '{0:08b}'.format(6)
'00000110'

Just to explain the parts of the formatting string:

• {} places a variable into a string
• 0 takes the variable at argument position 0
• : adds formatting options for this variable (otherwise it would represent decimal 6)
• 08 formats the number to eight digits zero-padded on the left
• b converts the number to its binary representation

If you're using a version of Python 3.6 or above, you can also use f-strings:

>>> f'{6:08b}'
'00000110'

I'm using Android Studio 3.0.1 and if the above answer doesn't work for you, try to change the icon type into Legacy and select Shape to None, the default one is Adaptive and Legacy.

Note: Some device has installed a launcher with automatically adding white background in icon, that's normal.

If you want it to work in browsers that don't support history.pushState and history.popState yet, the "old" way is to set the fragment identifier, which won't cause a page reload.

The basic idea is to set the window.location.hash property to a value that contains whatever state information you need, then either use the window.onhashchange event, or for older browsers that don't support onhashchange (IE < 8, Firefox < 3.6), periodically check to see if the hash has changed (using setInterval for example) and update the page. You will also need to check the hash value on page load to set up the initial content.

If you're using jQuery there's a hashchange plugin that will use whichever method the browser supports. I'm sure there are plugins for other libraries as well.

One thing to be careful of is colliding with ids on the page, because the browser will scroll to any element with a matching id.

Here's how I "automate" Dropping connected users in Oracle database:

# A shell script to Drop a Database Schema, forcing off any Connected Sessions (for example, before an Import) 
# Warning! With great power comes great responsibility.
# It is often advisable to take an Export before Dropping a Schema

if [ "$1" = "" ] 
then
    echo "Which Schema?"
    read schema
else
    echo "Are you sure? (y/n)"
    read reply
    [ ! $reply = y ] && return 1
    schema=$1
fi

sqlplus / as sysdba <<EOF
set echo on
alter user $schema account lock;
-- Exterminate all sessions!
begin     
  for x in ( select sid, serial# from v\$session where username=upper('$schema') )
  loop  
   execute immediate ( 'alter system kill session '''|| x.Sid || ',' || x.Serial# || ''' immediate' );  
  end loop;  
  dbms_lock.sleep( seconds => 2 ); -- Prevent ORA-01940: cannot drop a user that is currently connected
end;
/
drop user $schema cascade;

    /// </summary>

All of the previous answers explain what the OP 'should' do. I am explaining what the .SelectedText property is.

The .SelectedText property is not the text in the combobox. It is the text that is highlighted. It is the same as .SelectedText property for a textbox.

The following picture shows that the .SelectedText property would be equal to "ort".

Use subDays() method:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', Carbon::now()->subDays(30))
           ->get();

With OpenTURNS, I would use the BIC criteria to select the best distribution that fits such data. This is because this criteria does not give too much advantage to the distributions which have more parameters. Indeed, if a distribution has more parameters, it is easier for the fitted distribution to be closer to the data. Moreover, the Kolmogorov-Smirnov may not make sense in this case, because a small error in the measured values will have a huge impact on the p-value.

To illustrate the process, I load the El-Nino data, which contains 732 monthly temperature measurements from 1950 to 2010:

import statsmodels.api as sm
dta = sm.datasets.elnino.load_pandas().data
dta['YEAR'] = dta.YEAR.astype(int).astype(str)
dta = dta.set_index('YEAR').T.unstack()
data = dta.values

It is easy to get the 30 of built-in univariate factories of distributions with the GetContinuousUniVariateFactories static method. Once done, the BestModelBIC static method returns the best model and the corresponding BIC score.

sample = ot.Sample([[p] for p in data]) # data reshaping
tested_factories = ot.DistributionFactory.GetContinuousUniVariateFactories()
best_model, best_bic = ot.FittingTest.BestModelBIC(sample,
                                                   tested_factories)
print("Best=",best_model)

which prints:

Best= Beta(alpha = 1.64258, beta = 2.4348, a = 18.936, b = 29.254)

In order to graphically compare the fit to the histogram, I use the drawPDF methods of the best distribution.

import openturns.viewer as otv
graph = ot.HistogramFactory().build(sample).drawPDF()
bestPDF = best_model.drawPDF()
bestPDF.setColors(["blue"])
graph.add(bestPDF)
graph.setTitle("Best BIC fit")
name = best_model.getImplementation().getClassName()
graph.setLegends(["Histogram",name])
graph.setXTitle("Temperature (°C)")
otv.View(graph)

This produces:

More details on this topic are presented in the BestModelBIC doc. It would be possible to include the Scipy distribution in the SciPyDistribution or even with ChaosPy distributions with ChaosPyDistribution, but I guess that the current script fulfills most practical purposes.

First redirect stderr to stdout — the pipe; then redirect stdout to /dev/null (without changing where stderr is going):

command 2>&1 >/dev/null | grep 'something'

For the details of I/O redirection in all its variety, see the chapter on Redirections in the Bash reference manual.

Note that the sequence of I/O redirections is interpreted left-to-right, but pipes are set up before the I/O redirections are interpreted. File descriptors such as 1 and 2 are references to open file descriptions. The operation 2>&1 makes file descriptor 2 aka stderr refer to the same open file description as file descriptor 1 aka stdout is currently referring to (see dup2() and open()). The operation >/dev/null then changes file descriptor 1 so that it refers to an open file description for /dev/null, but that doesn't change the fact that file descriptor 2 refers to the open file description which file descriptor 1 was originally pointing to — namely, the pipe.

For Antlr 4 the java code generation process is below:-

java -cp antlr-4.5.3-complete.jar org.antlr.v4.Tool Exp.g

Update your jar name in classpath accordingly.

model.find({Branch:branch},function (err, docs){
  if (err) res.send(err)

  res.send(JSON.parse(JSON.stringify(docs)))
});

the root of this question is how to decode bytes to string?

this can be done with the JAVA NIO CharSet:

public final CharBuffer decode(ByteBuffer bb)

FileChannel channel = FileChannel.open(
  Paths.get("files/text-latin1.txt", StandardOpenOption.READ);
ByteBuffer buffer = ByteBuffer.allocate(1024);
channel.read(buffer);

CharSet latin1 = StandardCharsets.ISO_8859_1;
CharBuffer latin1Buffer = latin1.decode(buffer);

String result = new String(latin1Buffer.array());

• First we create a channel and read it in a buffer
• Then decode method decodes a Latin1 buffer to a char buffer
• We can then put the result, for instance, in a String

In Notepad++ v7.8.9 you can use the Tab key to increase the indention level, and use Shift + Tab to decrease the indentation level.

You can store it in a hidden field, OR store it in a javascript object (my preference) as the likely access will be via javascript.

NOTE: since you have an array, this would then be accessed as myvariable[0] for the first element (as you have it).

EDIT show example:

clip...
            success: function(msg)
            {
                LoadProviders(msg);
            },
...

var myvariable ="";

function LoadProviders(jdata)
{
  myvariable = jdata;
};
alert(myvariable[0].id);// shows "15aea3fa" in the alert

EDIT: Created this page:http://jsfiddle.net/GNyQn/ to demonstrate the above. This example makes the assumption that you have already properly returned your named string values in the array and simply need to store it per OP question. In the example, I also put the values of the first array returned (per OP example) into a div as text.

I am not sure why this has been viewed as "complex" as I see no simpler way to handle these strings in this array.

See: RFC 3092: Etymology of "Foo", D. Eastlake 3rd et al.

Quoting only the relevant definitions from that RFC for brevity:

2. Used very generally as a sample name for absolutely anything, esp. programs and files (esp. scratch files).

3. First on the standard list of metasyntactic variables used in syntax examples (bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, thud). [JARGON]

First add the new files:

svn add fileName

Then commit all new and modified files

svn ci <files_separated_by_space> -m "Commit message|ReviewID:XXXX"

If non source files are to be committed then

svn ci <files> -m "Commit msg|ReviewID:NON-SOURCE"

Here are step-by-step instructions for using Objective-C code (in this case, a framework provided by a third-party) in a Swift project:

1. Add any Objective-C file to your Swift project by choosing File -> New -> New File -> Objective-C File. Upon saving, Xcode will ask if you want to add a bridging header. Choose 'Yes'.
   _{(source: derrrick.com)}

In simple steps:

1. A prompt appears, and then click on OK... If it does not appear, then we create it manually like in the following... Create one header file from iOS source and give the name ProjectName-Bridging-Header (example: Test-Bridging-Header), and then go to build setting in the Swift compiler code -> Objective-C bridge add Objective-C bridge name ..(Test/Test-Bridging-Header.h). Yeah, that's complete.

2. Optionally, delete the Objective-C file you added (named "anything" in the GIF image above). You don't need it any more.

3. Open the bridging header file -- the filename is of the form [YourProject]-Bridging-Header.h. It includes an Xcode-provided comment. Add a line of code for the Objective-C file you want to include, such as a third-party framework. For example, to add Mixpanel to your project, you will need to add the following line of code to the bridging header file:

   #import "Mixpanel.h"

4. Now in any Swift file you can use existing Objective-C code, in the Swift syntax (in the case of this example, and you can call Mixpanel SDK methods, etc.). You need to familiarize yourself with how Xcode translates Objective-C to Swift. Apple's guide is a quick read. Or see this answer for an incomplete summary.

Example for Mixpanel:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    Mixpanel.sharedInstanceWithToken("your-token")
    return true
}

That's it!

Note: If you remove the bridging header file from your project, be sure to go into Build Settings and remove the value for "Objective-C Bridging Header" under "Swift Compiler - Code Generation".

However, if your website does not have a security certificate, it's on a shared hosting environment, and you don't want to get the "warning" when your website is being requested through https, you can't redirect it using htaccess. The reason is that the warning message gets triggered before the request even goes through to the htaccess file, so you have to fix it on the server. Go to /etc/httpd/conf.d/ssl.conf and comment out the part about the virtual server 443. But the odds are that your hosting provider won't give you that much control. So you would have to either move to a different host or buy the SSL just so the warning does not trigger before your htaccess has a chance to redirect.

var array = new Uint8Array(100);    
array[10] = 256;
array[10] === 0 // true

I verified in firefox and chrome, its really an array of bytes :

var array = new Uint8Array(1024*1024*50);  // allocates 50MBytes

Try writting the lambda with the same conditions as the delegate. like this:

  List<AnalysisObject> analysisObjects = 
    analysisObjectRepository.FindAll().Where(
    (x => 
       (x.ID == packageId)
    || (x.Parent != null && x.Parent.ID == packageId)
    || (x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)
    ).ToList();

Responding because this answer came up first for search when I was having the same issue:

[08S01][unixODBC][FreeTDS][SQL Server]Unable to connect: Adaptive Server is unavailable or does not exist

MSSQL named instances have to be configured properly without setting the port. (documentation on the freetds config says set instance or port NOT BOTH)

freetds.conf

[Name]
host = Server.com
instance = instance_name
#port = port is found automatically, don't define explicitly
tds version = 8.0
client charset = UTF-8

And in odbc.ini just because you can set Port, DON'T when you are using a named instance.

@FXML
ImageView image;

@Override
public void initialize(URL url, ResourceBundle rb) {
  image.setImage(new Image ("/about.jpg"));
}

Simply use! grep -v multiple times.

[root@server]# cat file

Exclude the line or match

[root@server]# cat file |grep -v 3

Exclude the line or match multiple

[root@server]# cat file |grep -v 3 |grep -v 5

@user187291 code works and only fails when + is not encoded.

I know this is very old post. But this worked to me.

$is_encoded = preg_match('~%[0-9A-F]{2}~i', $string);
if($is_encoded) {
 $string  = urlencode(urldecode(str_replace(['+','='], ['%2B','%3D'], $string)));
} else {
  $string = urlencode($string);
}

I think you need to push a revert commit. So pull from github again, including the commit you want to revert, then use git revert and push the result.

If you don't care about other people's clones of your github repository being broken, you can also delete and recreate the master branch on github after your reset: git push origin :master.

// this is how I always do it
for (i = n; --i >= 0;){
   ...
}
