How about this:

<command> > <filename.txt> & <filename.txt>

Example:

ipconfig /all > network.txt & network.txt

This will give the results in Notepad instead of the command prompt.

If you want to generate a number of random booleans you could use numpy's random module. From the documentation

np.random.randint(2, size=10)

will return 10 random uniform integers in the open interval [0,2). The size keyword specifies the number of values to generate.

CDerived::CDerived()
: CBase(...), iCount(0)  //this is the initialisation list. You can initialise member variables here too. (e.g. iCount := 0)
    {
    //construct body
    }

I encountered two issues related to the foregoing, when extracting text delimited by \ and /, and found a solution that fits both, other than using new RegExp, which requires \\\\ at the start. These findings are in Chrome and IE11.

The regular expression

/\\(.*)\//g

does not work. I think the // is interpreted as the start of a comment in spite of the escape character. The regular expression (equally valid in my case though not in general)

/\b/\\(.*)\/\b/g

does not work either. I think the second / terminates the regular expression in spite of the escape character.

What does work for me is to represent / as \x2F, which is the hexadecimal representation of /. I think that's more efficient and understandable than using new RegExp, but of course it needs a comment to identify the hex code.

Just to clarify how to unpack the arguments, and take care of missing arguments etc.

def func(**keyword_args):
  #-->keyword_args is a dictionary
  print 'func:'
  print keyword_args
  if keyword_args.has_key('b'): print keyword_args['b']
  if keyword_args.has_key('c'): print keyword_args['c']

def func2(*positional_args):
  #-->positional_args is a tuple
  print 'func2:'
  print positional_args
  if len(positional_args) > 1:
    print positional_args[1]

def func3(*positional_args, **keyword_args):
  #It is an error to switch the order ie. def func3(**keyword_args, *positional_args):
  print 'func3:'
  print positional_args
  print keyword_args

func(a='apple',b='banana')
func(c='candle')
func2('apple','banana')#It is an error to do func2(a='apple',b='banana')
func3('apple','banana',a='apple',b='banana')
func3('apple',b='banana')#It is an error to do func3(b='banana','apple')

With Java 9, we can use ProcessHandle which makes it easier to identify and control native processes:

ProcessHandle
  .allProcesses()
  .filter(p -> p.info().commandLine().map(c -> c.contains("firefox")).orElse(false))
  .findFirst()
  .ifPresent(ProcessHandle::destroy)

where "firefox" is the process to kill.

This:

• First lists all processes running on the system as a Stream<ProcessHandle>

• Lazily filters this stream to only keep processes whose launched command line contains "firefox". Both commandLine or command can be used depending on how we want to retrieve the process.

• Finds the first filtered process meeting the filtering condition.

• And if at least one process' command line contained "firefox", then kills it using destroy.

No import necessary as ProcessHandle is part of java.lang.

A public item is one that is accessible from any other class. You just have to know what object it is and you can use a dot operator to access it. Protected means that a class and its subclasses have access to the variable, but not any other classes, they need to use a getter/setter to do anything with the variable. A private means that only that class has direct access to the variable, everything else needs a method/function to access or change that data. Hope this helps.

Put the UNIQUE declaration within the column definition section; working example:

CREATE TABLE a (
    i INT,
    j INT,
    UNIQUE(i, j) ON CONFLICT REPLACE
);

You can do this pretty easily with Javascript+Jquery as below. If you want to exclude some column, just write an if statement inside the for loops to skip those columns. Hope this helps!

I think that your question is not defined well enough, for the following reason.

Answers relying on months_between have to deal with the following issue: that the function reports exactly one month between 2013-02-28 and 2013-03-31, and between 2013-01-28 and 2013-02-28, and between 2013-01-31 and 2013-02-28 (I suspect that some answerers have not used these functions in practice, or are now going to have to review some production code!)

This is documented behaviour, in which dates that are both the last in their respective months or which fall on the same day of the month are judged to be an integer number of months apart.

So, you get the same result of "1" when comparing 2013-02-28 with 2013-01-28 or with 2013-01-31, but comparing it with 2013-01-29 or 2013-01-30 gives 0.967741935484 and 0.935483870968 respectively -- so as one date approaches the other the difference reported by this function can increase.

If this is not an acceptable situation then you'll have to write a more complex function, or just rely on a calculation that assumes 30 (for example) days per month. In the latter case, how will you deal with 2013-02-28 and 2013-03-31?

You don't need a batch file, just do this from powershell :

powershell -C "gci | % {rni $_.Name ($_.Name -replace 'Vacation2010', 'December')}"

If you use ssl cert your ssl pipeline F5 settings configure.Important.

It is possible with EXISTS condition. WHERE EXISTS tests for the existence of any records in a subquery. EXISTS returns true if the subquery returns one or more records. Here is an example

UPDATE  TABLE_NAME 
SET val1=arg1 , val2=arg2
WHERE NOT EXISTS
    (SELECT FROM TABLE_NAME WHERE val1=arg1 AND val2=arg2)

The below code will work for Sql Server 2000/2005/2008

CREATE FUNCTION fnConcatVehicleCities(@VehicleId SMALLINT)
RETURNS VARCHAR(1000) AS
BEGIN
  DECLARE @csvCities VARCHAR(1000)
  SELECT @csvCities = COALESCE(@csvCities + ', ', '') + COALESCE(City,'')
  FROM Vehicles 
  WHERE VehicleId = @VehicleId 
  return @csvCities
END

-- //Once the User defined function is created then run the below sql

SELECT VehicleID
     , dbo.fnConcatVehicleCities(VehicleId) AS Locations
FROM Vehicles
GROUP BY VehicleID

Instead of using re.search use re.findall it will return you all matches in a List. Or you could also use re.finditer (which i like most to use) it will return an Iterator Object and you can just use it to iterate over all found matches.

line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
for match in re.finditer('<form>(.*?)</form>', line, re.S):
    print match.group(1)

Like this.

function printMousePos(event) {_x000D_
  document.body.textContent =_x000D_
    "clientX: " + event.clientX +_x000D_
    " - clientY: " + event.clientY;_x000D_
}_x000D_
_x000D_
document.addEventListener("click", printMousePos);

MouseEvent - MDN

MouseEvent.clientX Read only
The X coordinate of the mouse pointer in local (DOM content) coordinates.

MouseEvent.clientY Read only
The Y coordinate of the mouse pointer in local (DOM content) coordinates.

Place an asterisk(*) at the end of the destination path to skip the dispute of D and F.

Example:

xcopy "compressedOutput.xml" "../../Execute Scripts/APIAutomation/Libraries/rerunlastfailedbuild.xml*"

You can use css and the :hover pseudo-property. Here is a simple demo. It uses the following css:

a span.tooltip {display:none;}
a:hover span.tooltip {position:absolute;top:30px;left:20px;display:inline;border:2px solid green;}

Note that older browsers have limited support for :hover.

request.getContextPath()- returns root path of your application, while ../ - returns parent directory of a file.

You use request.getContextPath(), as it will always points to root of your application. If you were to move your jsp file from one directory to another, nothing needs to be changed. Now, consider the second approach. If you were to move your jsp files from one folder to another, you'd have to make changes at every location where you are referring your files.

Also, better approach of using request.getContextPath() will be to set 'request.getContextPath()' in a variable and use that variable for referring your path.

<c:set var="context" value="${pageContext.request.contextPath}" />
<script src="${context}/themes/js/jquery.js"></script>

PS- This is the one reason I can figure out. Don't know if there is any more significance to it.

According to mkdir's man page...

mkdir -m 777 dirname

iWasRobbed's answer is great, except there is an AVCaptureSession running in the background all the time. On my iPhone 4s it takes about 12% CPU power according to Instrument so my app took about 1% battery in a minute. In other words if the device is prepared for AV capture it's not cheap.

Using the code below my app requires 0.187% a minute so the battery life is more than 5x longer.

This code works just fine on any device (tested on both 3GS (no flash) and 4s). Tested on 4.3 in simulator as well.

#import <AVFoundation/AVFoundation.h>

- (void) turnTorchOn:(BOOL)on {

    Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
    if (captureDeviceClass != nil) {
        AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
        if ([device hasTorch] && [device hasFlash]){

            [device lockForConfiguration:nil];
            if (on) {
                [device setTorchMode:AVCaptureTorchModeOn];
                [device setFlashMode:AVCaptureFlashModeOn];
                torchIsOn = YES;
            } else {
                [device setTorchMode:AVCaptureTorchModeOff];
                [device setFlashMode:AVCaptureFlashModeOff];
                torchIsOn = NO;            
            }
            [device unlockForConfiguration];
        }
    }
}

As a general solution to install Python packages with binary dependencies [1] on Debian/Ubuntu:

sudo apt-get build-dep python-ldap
# installs system dependencies (but not the package itself)
pew workon my_virtualenv # enter your virtualenv
pip install python-ldap

You'll have to check the name of your Python package on Ubuntu versus PyPI. In this case they're the same.

Obviously doesn't work if the Python package is not in the Ubuntu repos.

[1] I learnt this trick when trying to pip install matplotlib on Ubuntu.

For HTML5:

Simply add to your <head>

 <meta charset="UTF-8"> 

Chrome DevTools, Safari Inspector and Firebug support getEventListeners(node).

Yep, just add the following function to your Utils class or something:

    public static string cleanForJSON(string s)
    {
        if (s == null || s.Length == 0) {
            return "";
        }

        char         c = '\0';
        int          i;
        int          len = s.Length;
        StringBuilder sb = new StringBuilder(len + 4);
        String       t;

        for (i = 0; i < len; i += 1) {
            c = s[i];
            switch (c) {
                case '\\':
                case '"':
                    sb.Append('\\');
                    sb.Append(c);
                    break;
                case '/':
                    sb.Append('\\');
                    sb.Append(c);
                    break;
                case '\b':
                    sb.Append("\\b");
                    break;
                case '\t':
                    sb.Append("\\t");
                    break;
                case '\n':
                    sb.Append("\\n");
                    break;
                case '\f':
                    sb.Append("\\f");
                    break;
                case '\r':
                    sb.Append("\\r");
                    break;
                default:
                    if (c < ' ') {
                        t = "000" + String.Format("X", c);
                        sb.Append("\\u" + t.Substring(t.Length - 4));
                    } else {
                        sb.Append(c);
                    }
                    break;
            }
        }
        return sb.ToString();
    }

There is a very simple and easy solution to your question:

var districtId = 210;

if (DistrictsEnum[districtId] != null) {

// Returns 'undefined' if the districtId not exists in the DistrictsEnum 
    model.handlingDistrictId = districtId;
}

A common use case I have is a dictionary of numpy arrays or lists where I know they're all the same length, and I just need to know one of them (e.g. I'm plotting timeseries data and each timeseries has the same number of timesteps). I often use this:

length = len(next(iter(d.values())))

Numeric precision refers to the maximum number of digits that are present in the number.

ie 1234567.89 has a precision of 9

Numeric scale refers to the maximum number of decimal places

ie 123456.789 has a scale of 3

Thus the maximum allowed value for decimal(5,2) is 999.99

I tried to change editor.tabSize to 4, but .editorConfig overrides whatever settings I had specified, so there is no need to change any configuration in user settings. You just need to edit .editorConfig file:

set indent_size = 4

C:\Program Files\Android\Android Studio\jre\bin>java -version
openjdk version "1.8.0_76-release"
OpenJDK Runtime Environment (build 1.8.0_76-release-b03)
OpenJDK 64-Bit Server VM (build 25.76-b03, mixed mode)

Somehow the Studio installer would install another version under:

C:\Program Files\Android\Android Studio\jre\jre\bin>java -version
openjdk version "1.8.0_76-release"
OpenJDK Runtime Environment (build 1.8.0_76-release-b03)
OpenJDK 64-Bit Server VM (build 25.76-b03, mixed mode)

where the latest version was installed the Java DevKit installer in:

C:\Program Files\Java\jre1.8.0_121\bin>java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

Need to clean up the Android Studio so it would use the proper latest 1.8.0 versions.

According to How to set Java SDK path in AndroidStudio? one could override with a specific JDK but when I renamed

C:\Program Files\Android\Android Studio\jre\jre\

to:

C:\Program Files\Android\Android Studio\jre\oldjre\

And restarted Android Studio, it would complain that the jre was invalid. When I tried to aecify an JDK to pick the one in C:\Program Files\Java\jre1.8.0_121\bin or:

C:\Program Files\Java\jre1.8.0_121\

It said that these folders are invalid. So I guess that the embedded version must have some special purpose.

Do it like this:

public static void main(String[] args) throws ParseException {

    String dateStr = "2016-10-19T14:15:36+08:00";
    Date date = javax.xml.bind.DatatypeConverter.parseDateTime(dateStr).getTime();

    System.out.println(date);

}

Here is the output:

I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):

        products.Columns.Add("col1", typeof(int));
        products.Columns.Add("col2", typeof(string));

        products.Rows.Add(1, "product 1");
        products.Rows.Add(2, "product 2");
        products.Rows.Add(3, "product 3");
        products.Rows.Add(4, "product 4");
        products.Rows.Add(5, "product 5");
        products.Rows.Add(6, "product 6");
        products.Rows.Add(7, "product 7");


        var grid = new GridView();
        grid.DataSource = products;
        grid.DataBind();

        Response.ClearContent();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
        Response.ContentType = "application/ms-excel";

        Response.Charset = "";
        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);

        grid.RenderControl(htw);

        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();

tl;dr

java.time.temporal.ChronoUnit.DAYS.between( 
    earlier.toLocalDate(), 
    later.toLocalDate() 
)

…or…

java.time.temporal.ChronoUnit.HOURS.between( 
    earlier.truncatedTo( ChronoUnit.HOURS )  , 
    later.truncatedTo( ChronoUnit.HOURS ) 
)

java.time

FYI, the Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

The equivalent of Joda-Time DateTime is ZonedDateTime.

ZoneId z = ZoneId.of( "Pacific/Auckland" ) ;
ZonedDateTime now = ZonedDateTime.now( z ) ;

Apparently you want to count the days by dates, meaning you want to ignore the time of day. For example, starting a minute before midnight and ending a minute after midnight should result in a single day. For this behavior, extract a LocalDate from your ZonedDateTime. The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate localDateStart = zdtStart.toLocalDate() ;
LocalDate localDateStop = zdtStop.toLocalDate() ;

Use the ChronoUnit enum to calculate elapsed days or other units.

long days = ChronoUnit.DAYS.between( localDateStart , localDateStop ) ;

Truncate

As for you asking about a more general way to do this counting where you are interested the delta of hours as hour-of-the-clock rather than complete hours as spans-of-time of sixty minutes, use the truncatedTo method.

Here is your example of 14:45 to 15:12 on same day.

ZoneId z = ZoneId.of( "America/Montreal" ); 
ZonedDateTime start = ZonedDateTime.of( 2017 , 1 , 17 , 14 , 45 , 0 , 0 , z );
ZonedDateTime stop = ZonedDateTime.of( 2017 , 1 , 17 , 15 , 12 , 0 , 0 , z );

long hours = ChronoUnit.HOURS.between( start.truncatedTo( ChronoUnit.HOURS ) , stop.truncatedTo( ChronoUnit.HOURS ) );

1

This does not work for days. Use toLocalDate() in this case.

About java.time

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

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

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

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

Where to obtain the java.time classes?

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

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

When I read in various places that hibernate didn't like you to assign to a collection, I assumed that the safest thing to do would obviously be to make it final like this:

class User {
  private final Set<Role> roles = new HashSet<>();

public void setRoles(Set<Role> roles) {
  this.roles.retainAll(roles);
  this.roles.addAll(roles);
}
}

However, this doesn't work, and you get the dreaded "no longer referenced" error, which is actually quite misleading in this case.

It turns out that hibernate calls your setRoles method AND it wants its special collection class installed here, and won't accept your collection class. This had me stumped for a LONG time, despite reading all the warnings about not assigning to your collection in your set method.

So I changed to this:

public class User {
  private Set<Role> roles = null;

  public void setRoles(Set<Role> roles) {
  if (this.roles == null) {
    this.roles = roles;
  } else {
    this.roles.retainAll(roles);
   this.roles.addAll(roles);
  }
}
}

So that on the first call, hibernate installs its special class, and on subsequent calls you can use the method yourself without wrecking everything. If you want to use your class as a bean, you probably need a working setter, and this at least seems to work.

Edit your script locally, then pipe it into ssh, e.g.

cat commands-to-execute-remotely.sh | ssh blah_server

where commands-to-execute-remotely.sh looks like your list above:

ls some_folder
./someaction.sh
pwd;

To add disabled attribute

$('#id').attr("disabled", "true");

To remove Disabled Attribute

$('#id').removeAttr('disabled');

var s = ",'first string','more','even more'";  
s.split(/'?,'?/).filter(function(v) { return v; });

Results in:

["first string", "more", "even more'"]

First split with commas possibly surrounded by single quotes,
then filter the non-truthy (empty) parts out.

I recently had the same issue on OS X Sierra with bash shell, and thanks to answers above I only had to edit the file

~/.bash_profile 

and append those lines

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

string cleanedString = System.Text.RegularExpressions.Regex.Replace(dirtyString,@"\s+"," ");

if (!$variablename) { Write-Host "variable is null" }

I hope this simple answer will is resolve the question. Source

Firebase is designed for real-time updates. It easily integrates with angular. Both are NoSQL databases. MongoDB can also do this with Angular through Socket.io integration. Meteor.js also makes use of MongoDB with an open socket connection for real-time updates.

MongoDB can be run locally, or hosted on many different cloud based providers. Firebase, in my opinion is great for smaller apps, very quick to get up and running. MongoDB is ideal for more robust larger apps, real-time integration is possible but it takes a bit more work.

You are referring to the section "2.3.5 Deploying the demo app" of this "Ruby on Rails Tutorial ":

In section 2.3.1 Planning the application, note that they did:

$ git remote add origin [email protected]:<username>/demo_app.git
$ git push origin master

That is why a simple git push worked (using here an ssh address).
Did you follow that step and made that first push?

wouldn't be a writable URI for pushing to a GitHub repo.

https://[email protected]/levelone/demo_app.git

should be more appropriate.
Check what git remote -v returns, and if you need to replace the remote address, as described in GitHub help page, use git remote --set-url.

git remote set-url origin https://[email protected]/levelone/demo_app.git

I create a common init for the designated and required. For convenience inits I delegate to init(frame:) with frame of zero.

Having zero frame is not a problem because typically the view is inside a ViewController's view; your custom view will get a good, safe chance to layout its subviews when its superview calls layoutSubviews() or updateConstraints(). These two functions are called by the system recursively throughout the view hierarchy. You can use either updateContstraints() or layoutSubviews(). updateContstraints() is called first, then layoutSubviews(). In updateConstraints() make sure to call super last. In layoutSubviews(), call super first.

Here's what I do:

@IBDesignable
class MyView: UIView {

      convenience init(args: Whatever) {
          self.init(frame: CGRect.zero)
          //assign custom vars
      }

      override init(frame: CGRect) {
           super.init(frame: frame)
           commonInit()
      }

      required init?(coder aDecoder: NSCoder) {
           super.init(coder: aDecoder)
           commonInit()
      }

      override func prepareForInterfaceBuilder() {
           super.prepareForInterfaceBuilder()
           commonInit()
      }

      private func commonInit() {
           //custom initialization
      }

      override func updateConstraints() {
           //set subview constraints here
           super.updateConstraints()
      }

      override func layoutSubviews() {
           super.layoutSubviews()
           //manually set subview frames here
      }

}

In my case junk files from editor caused the problem. I had a config as below:

#...
http {
 # ...
 include ../sites/*;
}

In the ../sites directory initially I had a default.config file. However, by mistake I saved duplicate files as default.config.save and default.config.save.1. Removing them resolved the issue.

Ya its possible to do without support of javascript..
We can use html5 auto focus attribute
For Example:

<input type="text" name="name" autofocus="autofocus" id="xax" />

If use it (autofocus="autofocus") in text field means that text field get focused when page gets loaded.. For more details:
http://www.hscripts.com/tutorials/html5/autofocus-attribute.html

My favourite UI tutorials all come from zetcode.com:

• wxWidgets (C++, cross platform)
• Win32api GUI (C, Windows)
• GTK+ (C, cross platform)
• Qt4 Tutorial (C++, cross platform)

These are tutorials I'd consider to be "starting tutorials". The example tutorial gets you up and going, but doesn't show you anything too advanced or give much explanation. Still, often, I find the big problem is "how do I start?" and these have always proved useful to me.

Take note of what is printed for x. You are trying to convert an array (basically just a list) into an int. length-1 would be an array of a single number, which I assume numpy just treats as a float. You could do this, but it's not a purely-numpy solution.

EDIT: I was involved in a post a couple of weeks back where numpy was slower an operation than I had expected and I realised I had fallen into a default mindset that numpy was always the way to go for speed. Since my answer was not as clean as ayhan's, I thought I'd use this space to show that this is another such instance to illustrate that vectorize is around 10% slower than building a list in Python. I don't know enough about numpy to explain why this is the case but perhaps someone else does?

import numpy as np
import matplotlib.pyplot as plt
import datetime

time_start = datetime.datetime.now()

# My original answer
def f(x):
    rebuilt_to_plot = []
    for num in x:
        rebuilt_to_plot.append(np.int(num))
    return rebuilt_to_plot

for t in range(10000):
    x = np.arange(1, 15.1, 0.1)
    plt.plot(x, f(x))

time_end = datetime.datetime.now()

# Answer by ayhan
def f_1(x):
    return np.int(x)

for t in range(10000):
    f2 = np.vectorize(f_1)
    x = np.arange(1, 15.1, 0.1)
    plt.plot(x, f2(x))

time_end_2 = datetime.datetime.now()

print time_end - time_start
print time_end_2 - time_end

To do this, simply type this in javascript:

function getParams(url) {
    var params = {};
    var parser = document.createElement('a');
    parser.href = url;
    var query = parser.search.substring(1);
    var vars = query.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        params[pair[0]] = decodeURIComponent(pair[1]);
    }
    return params;
};
var url = window.location.href;
getParams(url);

The default behavior of Commit PL/SQL block:

You should explicitly commit or roll back every transaction. Whether you issue the commit or rollback in your PL/SQL program or from a client program depends on the application logic. If you do not commit or roll back a transaction explicitly, the client environment determines its final state.

For example, in the SQLPlus environment, if your PL/SQL block does not include a COMMIT or ROLLBACK statement, the final state of your transaction depends on what you do after running the block. If you execute a data definition, data control, or COMMIT statement or if you issue the EXIT, DISCONNECT, or QUIT command, Oracle commits the transaction. If you execute a ROLLBACK statement or abort the SQLPlus session, Oracle rolls back the transaction.

Under Windows 10, the Task Manager can show you cumulative CPU hours. Just head to the "App history" tab and "Delete usage history". Now leave things running for an hour or two:

What this does NOT do is break down usage in browsers by tab. Quite often inactive tabs will do a tremendous amount of work, with each open tab using energy and slowing your PC.

You can use Tabindex to solve this issue. Also changing the order of the buttons would be a more efficient way to achieve this.

Change the order of the buttons and add float values to assign them the desired position you want to show in your HTML view.

Yes, you can.

@supports (-webkit-touch-callout: none) {
  /* CSS specific to iOS devices */ 
}

@supports not (-webkit-touch-callout: none) {
  /* CSS for other than iOS devices */ 
}

YMMV.

It works because only Safari Mobile implements -webkit-touch-callout: https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-touch-callout

Please note that @supports does not work in IE. IE will skip both of the above @support blocks above. To find out more see https://hacks.mozilla.org/2016/08/using-feature-queries-in-css/. It is recommended to not use @supports not because of this.

What about Chrome or Firefox on iOS? The reality is these are just skins over the WebKit rendering engine. Hence the above works everywhere on iOS as long as iOS policy does not change. See 2.5.6 in App Store Review Guidelines.

Warning: iOS may remove support for this in any new iOS release in the coming years. You SHOULD try a bit harder to not need the above CSS. An earlier version of this answer used -webkit-overflow-scrolling but a new iOS version removed it. As a commenter pointed out, there are other options to choose from: Go to Supported CSS Properties and search for "Safari on iOS".

You can use the Linux based syntax in one of your startup scripts. Just tested this on an OS X Mountain Lion box.

eg. in your ~/.bash_profile

export TERM="xterm-color" 
export PS1='\[\e[0;33m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '

This gives you a nice colored prompt. To add the colored ls output, you can add alias ls="ls -G".

To test, just run a source ~/.bash_profile to update your current terminal.

Side note about the colors: The colors are preceded by an escape sequence \e and defined by a color value, composed of [style;color+m] and wrapped in an escaped [] sequence. eg.

• red = \[\e[0;31m\]
• bold red (style 1) = \[\e[1;31m\]
• clear coloring = \[\e[0m\]

I always add a slightly modified color-scheme in the root's .bash_profile to make the username red, so I always see clearly if I'm logged in as root (handy to avoid mistakes if I have many terminal windows open).

In /root/.bash_profile:

PS1='\[\e[0;31m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '

For all my SSH accounts online I make sure to put the hostname in red, to distinguish if I'm in a local or remote terminal. Just edit the .bash_profile file in your home dir on the server.. If there is no .bash_profile file on the server, you can create it and it should be sourced upon login.

If this is not working as expected for you, please read some of the comments below since I'm not using MacOS very often..

If you want to do this on a remote server, check if the ~/.bash_profile file exists. If not, simply create it and it should be automatically sourced upon your next login.

Everything except for point 2 is correct. There are many different notations for signed ints, some implementations use the first, others use the last and yet others use something completely different. That all depends on the platform you're working with.

In Sharepoint 2013, getting data in JSON there is no format to convert date into date only format, because in that date should be in ISO format

With current HTML5 it should be possible to calculate the md5 hash of a binary file, But I think the step before that would be to convert the banary data BlobBuilder to a String, I am trying to do this step: but have not been successful.

Here is the code I tried: Converting a BlobBuilder to string, in HTML5 Javascript

I know that this is an old question but I am just going to place this here:

To prevent skype from using port 80 and port 443, open the Skype window, then click on the Tools menu and select Options.
Click on the Advanced tab, and go to the Connection sub-tab.
Uncheck the checkbox for Use port 80 and 443 as an alternative for additional incoming connections option.
Click on the Save button and then restart Skype.
After you restart skype, skype wont use port 88 or 443 anymore.

Hope this might help someone.

To make the numbers overwrite each other, you can do something like this:

for i in range(1,100):
    print "\r",i,

That should work as long as the number is printed in the first column.

EDIT: Here's a version that will work even if it isn't printed in the first column.

prev_digits = -1
for i in range(0,1000):
    print("%s%d" % ("\b"*(prev_digits + 1), i)),
    prev_digits = len(str(i))

I should note that this code was tested and works just fine in Python 2.5 on Windows, in the WIndows console. According to some others, flushing of stdout may be required to see the results. YMMV.

If you're developing an application that transfers data using AMF (fairly common in a particular set of GIS web APIs I use regularly), Fiddler does not currently provide an AMF decoder that will allow you to easily view the binary data in an easily-readable format. Charles provides this functionality.

First of all:

1. You must include tinymce jquery plugin in your page (jquery.tinymce.min.js)

2. One of the simplest and safest ways is to use getContent and setContent with triggerSave. Example:

   tinyMCE.get('editor_id').setContent(tinyMCE.get('editor_id').getContent()+_newdata);
   tinyMCE.triggerSave();
   

In java 8, it's convenient to use the new date lib and getEpochSecond method to get the timestamp (it's in second)

Instant.now().getEpochSecond();

I've used this process to attach a 3rd party Jar to an Android project in IDEA.

• Copy the Jar to your libs/ directory
• Open Project Settings (Ctrl Alt Shift S)
• Under the Project Settings panel on the left, choose Modules
• On the larger right pane, choose the Dependencies tab
• Press the Add... button on the far right of the screen (if you have a smaller screen like me, you may have to drag resize to the right in order to see it)
• From the dropdown of Add options, choose "Library". A "Choose Libraries" dialog will appear.
• Press "New Library..."
• Choose a suitable title for the library
• Press "Attach Classes..."
• Choose the Jar from your libs/ directory, and press OK to dismiss

The library should now be recognised.

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

ObservableCollection is a collection that allows code outside the collection be aware of when changes to the collection (add, move, remove) occur. It is used heavily in WPF and Silverlight but its use is not limited to there. Code can add event handlers to see when the collection has changed and then react through the event handler to do some additional processing. This may be changing a UI or performing some other operation.

The code below doesn't really do anything but demonstrates how you'd attach a handler in a class and then use the event args to react in some way to the changes. WPF already has many operations like refreshing the UI built in so you get them for free when using ObservableCollections

class Handler
{
    private ObservableCollection<string> collection;

    public Handler()
    {
        collection = new ObservableCollection<string>();
        collection.CollectionChanged += HandleChange;
    }

    private void HandleChange(object sender, NotifyCollectionChangedEventArgs e)
    {
        foreach (var x in e.NewItems)
        {
            // do something
        }

        foreach (var y in e.OldItems)
        {
            //do something
        }
        if (e.Action == NotifyCollectionChangedAction.Move)
        {
            //do something
        }
    }
}

The Android Training class, "Displaying Bitmaps Efficiently", offers some great information for understanding and dealing with the exception java.lang.OutOfMemoryError: bitmap size exceeds VM budget when loading Bitmaps.

Read Bitmap Dimensions and Type

The BitmapFactory class provides several decoding methods (decodeByteArray(), decodeFile(), decodeResource(), etc.) for creating a Bitmap from various sources. Choose the most appropriate decode method based on your image data source. These methods attempt to allocate memory for the constructed bitmap and therefore can easily result in an OutOfMemory exception. Each type of decode method has additional signatures that let you specify decoding options via the BitmapFactory.Options class. Setting the inJustDecodeBounds property to true while decoding avoids memory allocation, returning null for the bitmap object but setting outWidth, outHeight and outMimeType. This technique allows you to read the dimensions and type of the image data prior to construction (and memory allocation) of the bitmap.

BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeResource(getResources(), R.id.myimage, options);
int imageHeight = options.outHeight;
int imageWidth = options.outWidth;
String imageType = options.outMimeType;

To avoid java.lang.OutOfMemory exceptions, check the dimensions of a bitmap before decoding it, unless you absolutely trust the source to provide you with predictably sized image data that comfortably fits within the available memory.

Load a scaled down version into Memory

Now that the image dimensions are known, they can be used to decide if the full image should be loaded into memory or if a subsampled version should be loaded instead. Here are some factors to consider:

• Estimated memory usage of loading the full image in memory.
• The amount of memory you are willing to commit to loading this image given any other memory requirements of your application.
• Dimensions of the target ImageView or UI component that the image is to be loaded into.
• Screen size and density of the current device.

For example, it’s not worth loading a 1024x768 pixel image into memory if it will eventually be displayed in a 128x96 pixel thumbnail in an ImageView.

To tell the decoder to subsample the image, loading a smaller version into memory, set inSampleSize to true in your BitmapFactory.Options object. For example, an image with resolution 2048x1536 that is decoded with an inSampleSize of 4 produces a bitmap of approximately 512x384. Loading this into memory uses 0.75MB rather than 12MB for the full image (assuming a bitmap configuration of ARGB_8888). Here’s a method to calculate a sample size value that is a power of two based on a target width and height:

public static int calculateInSampleSize(
        BitmapFactory.Options options, int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        final int halfHeight = height / 2;
        final int halfWidth = width / 2;

        // Calculate the largest inSampleSize value that is a power of 2 and keeps both
        // height and width larger than the requested height and width.
        while ((halfHeight / inSampleSize) > reqHeight
                && (halfWidth / inSampleSize) > reqWidth) {
            inSampleSize *= 2;
        }
    }

    return inSampleSize;
}

Note: A power of two value is calculated because the decoder uses a final value by rounding down to the nearest power of two, as per the inSampleSize documentation.

To use this method, first decode with inJustDecodeBounds set to true, pass the options through and then decode again using the new inSampleSize value and inJustDecodeBounds set to false:

public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId,
    int reqWidth, int reqHeight) {

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    BitmapFactory.decodeResource(res, resId, options);

    // Calculate inSampleSize
    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    return BitmapFactory.decodeResource(res, resId, options);
}

This method makes it easy to load a bitmap of arbitrarily large size into an ImageView that displays a 100x100 pixel thumbnail, as shown in the following example code:

mImageView.setImageBitmap(
    decodeSampledBitmapFromResource(getResources(), R.id.myimage, 100, 100));

You can follow a similar process to decode bitmaps from other sources, by substituting the appropriate BitmapFactory.decode* method as needed.

you can simply do this..

 <img src={"http://img.example.com/test/" + this.props.url +"/1.jpg"}/>

I got stuck with the same problem and after read and try all the suggestions above I just tried to replace manually this image (which you can find it here) in the CSS after downloaded it and saved in the images folder on my app and voilá, problem solved!

here is the CSS:

.ui-state-default .ui-icon {
        background-image: url("../img/ui-icons_888888_256x240.png");
}

Don't type python test.py from inside the Python interpreter. Type it at the command prompt, like so:

If your signatures differ only in the number of arguments, using default arguments is the right way to do it. If you want to be able to pass in different kinds of argument, I would try to avoid the isinstance-based approach mentioned in another answer, and instead use keyword arguments.

If using just keyword arguments becomes unwieldy, you can combine it with classmethods (the bzrlib code likes this approach). This is just a silly example, but I hope you get the idea:

class C(object):

    def __init__(self, fd):
        # Assume fd is a file-like object.
        self.fd = fd

    @classmethod
    def fromfilename(cls, name):
        return cls(open(name, 'rb'))

# Now you can do:
c = C(fd)
# or:
c = C.fromfilename('a filename')

Notice all those classmethods still go through the same __init__, but using classmethods can be much more convenient than having to remember what combinations of keyword arguments to __init__ work.

isinstance is best avoided because Python's duck typing makes it hard to figure out what kind of object was actually passed in. For example: if you want to take either a filename or a file-like object you cannot use isinstance(arg, file), because there are many file-like objects that do not subclass file (like the ones returned from urllib, or StringIO, or...). It's usually a better idea to just have the caller tell you explicitly what kind of object was meant, by using different keyword arguments.

You can map another entity based on this class (you should use entity-name in order to distinct the two) and the second one will be kind of dto (dont forget that dto has design issues ). you should define the second one as readonly and give it a good name in order to be clear that this is not a regular entity. by the way select only few columns is called projection , so google with it will be easier.

alternative - you can create named query with the list of fields that you need (you put them in the select ) or use criteria with projection

public function randomString($length = 8)
{
    $characters = implode([
        'ABCDEFGHIJKLMNOPORRQSTUWVXYZ',
        'abcdefghijklmnoprqstuwvxyz',
        '0123456789',
        //'!@#$%^&*?'
    ]);

    $charactersLength = strlen($characters) - 1;
    $string           = '';

    while ($length) {
        $string .= $characters[mt_rand(0, $charactersLength)];
        --$length;
    }

    return $string;
}

For those how tumble here like me looking for a way to a "SQL Like" method in LINQ, I've something that is working very good.

I'm in a case where I cannot alter the Database in any way to change the column collation. So I've to find a way in my LINQ to do it.

I'm using the helper method SqlFunctions.PatIndex witch act similarly to the real SQL LIKE operator.

First I need enumerate all possible diacritics (a word that I just learned) in the search value to get something like:

déjà     => d[éèêëeÉÈÊËE]j[aàâäAÀÂÄ]
montreal => montr[éèêëeÉÈÊËE][aàâäAÀÂÄ]l
montréal => montr[éèêëeÉÈÊËE][aàâäAÀÂÄ]l

and then in LINQ for exemple:

var city = "montr[éèêëeÉÈÊËE][aàâäAÀÂÄ]l";
var data = (from loc in _context.Locations
                     where SqlFunctions.PatIndex(city, loc.City) > 0
                     select loc.City).ToList();

So for my needs I've written a Helper/Extension method

   public static class SqlServerHelper
    {

        private static readonly List<KeyValuePair<string, string>> Diacritics = new List<KeyValuePair<string, string>>()
        {
            new KeyValuePair<string, string>("A", "aàâäAÀÂÄ"),
            new KeyValuePair<string, string>("E", "éèêëeÉÈÊËE"),
            new KeyValuePair<string, string>("U", "uûüùUÛÜÙ"),
            new KeyValuePair<string, string>("C", "cçCÇ"),
            new KeyValuePair<string, string>("I", "iîïIÎÏ"),
            new KeyValuePair<string, string>("O", "ôöÔÖ"),
            new KeyValuePair<string, string>("Y", "YŸÝýyÿ")
        };

        public static string EnumarateDiacritics(this string stringToDiatritics)
        {
            if (string.IsNullOrEmpty(stringToDiatritics.Trim()))
                return stringToDiatritics;

            var diacriticChecked = string.Empty;

            foreach (var c in stringToDiatritics.ToCharArray())
            {
                var diac = Diacritics.FirstOrDefault(o => o.Value.ToCharArray().Contains(c));
                if (string.IsNullOrEmpty(diac.Key))
                    continue;

                //Prevent from doing same letter/Diacritic more than one time
                if (diacriticChecked.Contains(diac.Key))
                    continue;

                diacriticChecked += diac.Key;

                stringToDiatritics = stringToDiatritics.Replace(c.ToString(), "[" + diac.Value + "]");
            }

            stringToDiatritics = "%" + stringToDiatritics + "%";
            return stringToDiatritics;
        }
    }

If any of you have suggestion to enhance this method, I'll be please to hear you.

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

There several answers here that don't handle simple edge cases like negative step, wrong start, stop etc. Here's the version that handles many of these cases correctly giving same behaviour as native range():

def frange(start, stop=None, step=1):
  if stop is None:
    start, stop = 0, start
  steps = int((stop-start)/step)
  for i in range(steps):
    yield start
    start += step  

Note that this would error out step=0 just like native range. One difference is that native range returns object that is indexable and reversible while above doesn't.

You can play with this code and test cases here.

Suppose you have multiple project in the solution. Select the project that you want to view in browser and select 'Set as StartUp Project'. In your multiple project soln which was the main, the visual studio was unable to identify. this was the main problem.

The key is to encapsulate the expression in parentheses after the @ delimiter. You can make any compound expression work this way.

As was mentioned before, you could do something like that

public String getVal(WebElement webElement) {
    JavascriptExecutor e = (JavascriptExecutor) driver;
    return (String) e.executeScript(String.format("return $('#%s').val();", webElement.getAttribute("id")));
}

But as you can see, your element must have an id attribute, and also, jquery on your page.

Use : ' to open and ' to close.

I had this problem while trying to brew upgrade on MacOS X 10.7.5.

Unfortunately mysql was also upgraded to 5.6.10 from 5.5.14. Tried the new, did not work.

I decided to go back to my old setup and did a

brew switch mysql 5.5.14

This did not solve the problem. Elsewhere I read and did this, voila! All was back :)

cd /usr/local/var/mysql

Using jackson, you can do it as follows:

    ObjectMapper mapper = new ObjectMapper();
    String clientFilterJson = "";
    try {
        clientFilterJson = mapper.writeValueAsString(filterSaveModel);
    } catch (IOException e) {
        e.printStackTrace();
    }

If you think the performance of the query will be better using the index, how could you force the query to use the index?

First you would of course verify that the index gave a better result for returning the complete data set, right?

The index hint is the key here, but the more up to date way of specifying it is with the column naming method rather than the index naming method. In your case you would use:

select /*+ index(table_name (column_having_index)) */ *
from   table_name
where  column_having_index="some value"; 

In more complex cases you might ...

select /*+ index(t (t.column_having_index)) */ *
from   my_owner.table_name t,
       ...
where  t.column_having_index="some value"; 

With regard to composite indexes, I'm not sure that you need to specify all columns, but it seems like a good idea. See the docs here http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#autoId18 on multiple index_specs and use of index_combine for multiple indexes, and here http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#BABGFHCH for the specification of multiple columns in the index_spec.

Here is a simple explanation about how to create a temp dir using templates.

1. Creates a temporary file or directory, safely, and prints its name.
2. TEMPLATE must contain at least 3 consecutive 'X's in last component.
3. If TEMPLATE is not specified, it will use tmp.XXXXXXXXXX
4. directories created are u+rwx, minus umask restrictions.

PARENT_DIR=./temp_dirs # (optional) specify a dir for your tempdirs
mkdir $PARENT_DIR

TEMPLATE_PREFIX='tmp' # prefix of your new tempdir template
TEMPLATE_RANDOM='XXXX' # Increase the Xs for more random characters
TEMPLATE=${PARENT_DIR}/${TEMPLATE_PREFIX}.${TEMPLATE_RANDOM}

# create the tempdir using your custom $TEMPLATE, which may include
# a path such as a parent dir, and assign the new path to a var
NEW_TEMP_DIR_PATH=$(mktemp -d $TEMPLATE)
echo $NEW_TEMP_DIR_PATH

# create the tempdir in parent dir, using default template
# 'tmp.XXXXXXXXXX' and assign the new path to a var
NEW_TEMP_DIR_PATH=$(mktemp -p $PARENT_DIR)
echo $NEW_TEMP_DIR_PATH

# create a tempdir in your systems default tmp path e.g. /tmp 
# using the default template 'tmp.XXXXXXXXXX' and assign path to var
NEW_TEMP_DIR_PATH=$(mktemp -d)
echo $NEW_TEMP_DIR_PATH

# Do whatever you want with your generated temp dir and var holding its path

To state the obvious, the cup represents outerScopeVar.

Asynchronous functions be like...

Just create a data.frame with 0 length variables

eg

nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)

## 'data.frame':    0 obs. of  3 variables:
##  $ x: num 
##  $ y: int 
##  $ z: Factor w/ 0 levels: 

or to create a data.frame with 5 columns named a,b,c,d,e

nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))

In order to take advantage of the auto-incrementing capability of the column, do not supply a value for that column when inserting rows. The database will supply a value for you.

INSERT INTO test.authors (
   instance_id,host_object_id,check_type,is_raw_check,
   current_check_attempt,max_check_attempts,state,state_type,
   start_time,start_time_usec,end_time,end_time_usec,command_object_id,
   command_args,command_line,timeout,early_timeout,execution_time,
   latency,return_code,output,long_output,perfdata
) VALUES (
   '1','67','0','0','1','10','0','1','2012-01-03 12:50:49','108929',

   '','rta=2.860000m=0%;80;100;0'
);

Button butt= new Button(_context);
butt.setTextAppearance(_context, R.style.ButtonFontStyle);

and in res/values/style.xml

<resources>   
    <style name="ButtonFontStyle">
            <item name="android:textSize">12sp</item>
    </style>
</resources>

My fellows,

In January 2019 I used a code made before:

 <script type="text/javascript">   
    function imprimir() {
        var divToPrint=document.getElementById("ConsutaBPM");
        newWin= window.open("");
        newWin.document.write(divToPrint.outerHTML);
        newWin.print();
        newWin.close();
    }
</script>

To undestand: ConsutaBPM is a DIV which contains inside phrases and tables. I wanted to print ALL, titles, table, and others. The problem was when TRIED to print the TABLE...

The table mas be defined with BORDER and CELLPADDING:

<table border='1' cellpadding='1' id='Tablbpm1' >

It worked fine!!!

I tested this command:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell input keyevent 19 && adb shell input keyevent 19 && adb shell input keyevent 23

and only works on window's prompt, maybe because of some driver

The adb shell svc wifi enable|disable solution only works with root permissions.

Simple pipe trick, ||, with some .vbs used at top of your batch. It will exit regular and restart as administrator.

@AT>NUL||echo set shell=CreateObject("Shell.Application"):shell.ShellExecute "%~dpnx0",,"%CD%", "runas", 1:set shell=nothing>%~n0.vbs&start %~n0.vbs /realtime& timeout 1 /NOBREAK>nul& del /Q %~n0.vbs&cls&exit

It also del /Q the temp.vbs when it's done using it.

Weird reason I've never seen before: If you're using a "parent > child" selector outside of the media query (in Firefox 69) it could break the media query. I'm not sure why this happens, but for my scenario this did not work...

@media whatever {
    #child { display: none; }
}

But adding the parent to match some other CSS further up the page, this works...

#parent > #child { display: none; }

Seems like specifying the parent should not matter, since an id is very specific and there should be no ambiguity. Maybe it's a bug in Firefox?

s = "I have white space".delete(' ')

And to emulate PHP's trim() function:

s = "   I have leading and trailing white space   ".strip

You've specifically mentioned a "variable-length array" in your question, so neither of the existing two answers (as I write this) are quite right.

Java doesn't have any concept of a "variable-length array", but it does have Collections, which serve in this capacity. Any collection (technically any "Iterable", a supertype of Collections) can be looped over as simply as this:

Collection<Thing> things = ...;
for (Thing t : things) {
  System.out.println(t);
}

EDIT: it's possible I misunderstood what he meant by 'variable-length'. He might have just meant it's a fixed length but not every instance is the same fixed length. In which case the existing answers would be fine. I'm not sure what was meant.

If you want to connect to a MySQL database using JavaScript, you can use Node.js and a library called mysql. You can create queries, and get results as an array of registers. If you want to try it, you can use my project generator to create a backend and choose MySQL as the database to connect. Then, just expose your new REST API or GraphQL endpoint to your front and start working with your MySQL database.

OLD ANSWER LEFT BY NOSTALGIA

THEN

As I understand the question and correct me if I am wrong, it refers to the classic server model with JavaScript only on the client-side. In this classic model, with LAMP servers (Linux, Apache, MySQL, PHP) the language in contact with the database was PHP, so to request data to the database you need to write PHP scripts and echo the returning data to the client. Basically, the distribution of the languages according to physical machines was:

1. Server Side: PHP and MySQL.
2. Client Side: HTML/CSS and JavaScript.

This answered to an MVC model (Model, View, Controller) where we had the following functionality:

1. MODEL: The model is what deals with the data, in this case, the PHP scripts that manage variables or that access data stored, in this case in our MySQL database and send it as JSON data to the client.
2. VIEW: The view is what we see and it should be completely independent of the model. It just needs to show the data contained in the model, but it shouldn't have relevant data on it. In this case, the view uses HTML and CSS. HTML to create the basic structure of the view, and CSS to give the shape to this basic structure.
3. CONTROLLER: The controller is the interface between our model and our view. In this case, the language used is JavaScript and it takes the data the model send us as a JSON package and put it inside the containers that offer the HTML structure. The way the controller interacts with the model is by using AJAX. We use GET and POST methods to call PHP scripts on the server-side and to catch the returned data from the server.

For the controller, we have really interesting tools like jQuery, as "low-level" library to control the HTML structure (DOM), and then new, more high-level ones as Knockout.js that allow us to create observers that connect different DOM elements updating them when events occur. There is also Angular.js by Google that works in a similar way, but seems to be a complete environment. To help you to choose among them, here you have two excellent analyses of the two tools: Knockout vs. Angular.js and Knockout.js vs. Angular.js. I am still reading. Hope they help you.

NOW

In modern servers based in Node.js, we use JavaScript for everything. Node.js is a JavaScript environment with many libraries that work with Google V8, Chrome JavaScript engine. The way we work with these new servers is:

1. Node.js and Express: The mainframe where the server is built. We can create a server with a few lines of code or even use libraries like Express to make even easier to create the server. With Node.js and Express, we will manage the petitions to the server from the clients and will answer them with the appropriate pages.
2. Jade: To create the pages we use a templating language, in this case, Jade, that allow us to write web pages as we were writing HTML but with differences (it take a little time but is easy to learn). Then, in the code of the server to answer the client's petitions, we just need to render the Jade code into a "real" HTML code.
3. Stylus: Similar to Jade but for CSS. In this case, we use a middleware function to convert the stylus file into a real CSS file for our page.

Then we have a lot of packages we can install using the NPM (Node.js package manager) and use them directly in our Node.js server just requiring it (for those of you that want to learn Node.js, try this beginner tutorial for an overview). And among these packages, you have some of them to access databases. Using this you can use JavaScript on the server-side to access My SQL databases.

But the best you can do if you are going to work with Node.js is to use the new NoSQL databases like MongoDB, based on JSON files. Instead of storing tables like MySQL, it stores the data in JSON structures, so you can put different data inside each structure like long numeric vectors instead of creating huge tables for the size of the biggest one.

I hope this brief explanation becomes useful to you, and if you want to learn more about this, here you have some resources you can use:

• Egghead: This site is full of great short tutorials about JavaScript and its environment. It worths a try. And the make discounts from time to time.
• Code School: With a free and very interesting course about Chrome Developer tools to help you to test the client-side.
• Codecademy: With free courses about HTML, CSS, JavaScript, jQuery, and PHP that you can follow with online examples.
• 10gen Education: With everything you need to know about MongoDB in tutorials for different languages.
• W3Schools: This one has tutorials about all this and you can use it as a reference place because it has a lot of shortcode examples really useful.
• Udacity: A place with free video courses about different subjects with a few interesting ones about web development and my preferred, an amazing WebGL course for 3D graphics with JavaScript.

I hope it helps you to start.

Have fun!

A way to do this would be to set the color of the element to black, and then fade to the color of the background like this:

<style> 
p {
animation-name: example;
animation-duration: 2s;
}

@keyframes example {
from {color:black;}
to {color:white;}
}
</style>
<p>I am FADING!</p>

I hope this is what you needed!

You can use a broadcast that is called in OnResume ()

For example:

int vh = 0;   
int vw = 0;

public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.maindemo);  //<- includes the grid called "board"

      registerReceiver(new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                TableLayout tl = (TableLayout) findViewById(R.id.board);  
                tl = (TableLayout) findViewById(R.id.board);
                vh = tl.getHeight();       
                vw = tl.getWidth();               
            }
      }, new IntentFilter("Test"));
}

protected void onResume() {
        super.onResume();

        Intent it = new Intent("Test");
        sendBroadcast(it);

}

You can not get the height of a view in OnCreate (), onStart (), or even in onResume () for the reason that kcoppock responded

in your <head>

<meta id="viewport"
      name="viewport"
      content="width=1024, height=768, initial-scale=0, minimum-scale=0.25" />

somewhere in your javascript

document.getElementById("viewport").setAttribute("content",
      "initial-scale=0.5; maximum-scale=1.0; user-scalable=0;");

... but good luck with tweaking it for your device, fiddling for hours... and i'm still not there!

Assuming you are in the directory where myJar.jar file is and that myClass has a public static void main() method on it:

You use the following command line:

java -cp ./myJar.jar myClass

Where:

1. myJar.jar is in the current path, note that . isn't in the current path on most systems. A fully qualified path is preferred here as well.

2. myClass is a fully qualified package path to the class, the example assumes that myClass is in the default package which is bad practice, if it is in a nested package it would be com.mycompany.mycode.myClass.

You should be able to use the "ours" merge strategy to overwrite master with seotweaks like this:

git checkout seotweaks
git merge -s ours master
git checkout master
git merge seotweaks

The result should be your master is now essentially seotweaks.

(-s ours is short for --strategy=ours)

From the docs about the 'ours' strategy:

This resolves any number of heads, but the resulting tree of the merge is always that of the current branch head, effectively ignoring all changes from all other branches. It is meant to be used to supersede old development history of side branches. Note that this is different from the -Xours option to the recursive merge strategy.

Update from comments: If you get fatal: refusing to merge unrelated histories, then change the second line to this: git merge --allow-unrelated-histories -s ours master

Null OR an empty string?

if (!empty($user)) {}

Use empty().

After realizing that $user ~= $_POST['user'] (thanks matt):

var uservariable='<?php 
    echo ((array_key_exists('user',$_POST)) || (!empty($_POST['user']))) ? $_POST['user'] : 'Empty Username Input';
?>';

You need set the keyframes animation in you CSS. And use the keyframe with jQuery:

$('#myTest').css({"animation":"my-animation 2s infinite"});

#myTest {_x000D_
  width: 50px;_x000D_
  height: 50px;_x000D_
  background: black;_x000D_
}_x000D_
_x000D_
@keyframes my-animation {_x000D_
  0% {_x000D_
    background: red;  _x000D_
  }_x000D_
  50% {_x000D_
    background: blue;  _x000D_
  }_x000D_
  100% {_x000D_
    background: green;  _x000D_
  }_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="myTest"></div>

You can use the git show command.

To get the last commit date from git repository in a long(Unix epoch timestamp):

• Command: git show -s --format=%ct
• Result: 1605103148

Note: You can visit the git-show documentation to get a more detailed description of the options.

Your code is correct. I tested:

r = requests.get("http://www.google.com")
print(r.content)

And it returned plenty of content. Check the url, try "http://www.google.com". Cheers!

MySQL recommends using indexes for a variety of reasons including elimination of rows between conditions: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html

This makes your datetime column an excellent candidate for an index if you are going to be using it in conditions frequently in queries. If your only condition is BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 30 DAY) and you have no other index in the condition, MySQL will have to do a full table scan on every query. I'm not sure how many rows are generated in 30 days, but as long as it's less than about 1/3 of the total rows it will be more efficient to use an index on the column.

Your question about creating an efficient database is very broad. I'd say to just make sure that it's normalized and all appropriate columns are indexed (i.e. ones used in joins and where clauses).

I've never actually used this, but try view.getClass().getGenericSuperclass()

I've tried the solution presented in the accepted answer and it did not work for me. I wanted to share what DID work for me as it might help someone else. I've found this solution here.

Basically what you need to do is put your .so files inside a a folder named lib (Note: it is not libs and this is not a mistake). It should be in the same structure it should be in the APK file.

In my case it was:
Project:
|--lib:
|--|--armeabi:
|--|--|--.so files.

So I've made a lib folder and inside it an armeabi folder where I've inserted all the needed .so files. I then zipped the folder into a .zip (the structure inside the zip file is now lib/armeabi/*.so) I renamed the .zip file into armeabi.jar and added the line compile fileTree(dir: 'libs', include: '*.jar') into dependencies {} in the gradle's build file.

This solved my problem in a rather clean way.

According to the docs:

"If the onPressed callback is null, then the button will be disabled and by default will resemble a flat button in the disabledColor."

https://docs.flutter.io/flutter/material/RaisedButton-class.html

So, you might do something like this:

    RaisedButton(
      onPressed: calculateWhetherDisabledReturnsBool() ? null : () => whatToDoOnPressed,
      child: Text('Button text')
    );

This code work good to me and look more simple. Necessary to call a function with specific parameter.

var btn = document.createElement("BUTTON");  //<button> element
var t = document.createTextNode("MyButton"); // Create a text node
btn.appendChild(t);   

btn.onclick = function(){myFunction(myparameter)};  
document.getElementById("myView").appendChild(btn);//to show on myView

this worked for me!

if some_queryset.objects.all().exists(): print("this table is not empty")

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

Check that the directory the keytool executable is in is on your %PATH% environment variable.

For example, on my Windows 7 machine, it is in C:\Program Files (x86)\Java\jre6\bin, and my %PATH% variable looks like C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Program Files (x86)\Java\jre6\bin;C:\WINDOWS\System32\WindowsPowerShell\v1.0\ (and many other entries)

You can use OR() to group expressions (as well as AND()):

=IF(OR(condition1, condition2), true, false)

=IF(AND(condition1, condition2), true, false)

So if you wanted to test for "cat" and "22":

=IF(AND(SEARCH("cat",a1),SEARCH("22",a1)),"cat and 22","none")

It can't be stated enough that you can use console.debug(object) for this. This technique will save you literally hundreds of hours a year if you do this for a living :p

Following solution is better than bootbox.js, because

• It can do everything bootbox.js can do;
• The use syntax is simpler
• It allows you to elegantly control the color of your message using "error", "warning" or "info"
• Bootbox is 986 lines long, mine only 110 lines long

Install package : Microsoft.AspNet.WebApi.Cors

go to : App_Start --> WebApiConfig

Add :

var cors = new EnableCorsAttribute("http://localhost:4200", "", ""); config.EnableCors(cors);

Note : If you add '/' as end of the particular url not worked for me.

    $myarray = array_filter($myarray, 'strlen');  //removes null values but leaves "0"
    $myarray = array_filter($myarray);            //removes all null values

Despite the fact that this is a very old question and probably many of the beforementioned ideas solved many problems, I still want to share the solution with the community that fixed my problem.

I found that the problem was a function called "hasItem" which I was using to check whether or not a JSON-Array contains a specific item. In my case I checked for a value of type Long.

And this led to the problem.

Somehow, the Matchers have problems with values of type Long. (I do not use JUnit or Rest-Assured so much so idk. exactly why, but I guess that the returned JSON-data does just contain Integers.)

So what I did to actually fix the problem was the following. Instead of using:

long ID = ...;

...
.then().assertThat()
  .body("myArray", hasItem(ID));

you just have to cast to Integer. So the working code looked like this:

long ID = ...;

...
.then().assertThat()
  .body("myArray", hasItem((int) ID));

That's probably not the best solution, but I just wanted to mention that the exception can also be thrown because of wrong/unknown data types.

The answer lies in which constructors the LinkedHashSet uses to construct the base class:

public LinkedHashSet(int initialCapacity, float loadFactor) {
    super(initialCapacity, loadFactor, true);      // <-- boolean dummy argument
}

...

public LinkedHashSet(int initialCapacity) {
    super(initialCapacity, .75f, true);            // <-- boolean dummy argument
}

...

public LinkedHashSet() {
    super(16, .75f, true);                         // <-- boolean dummy argument
}

...

public LinkedHashSet(Collection<? extends E> c) {
    super(Math.max(2*c.size(), 11), .75f, true);   // <-- boolean dummy argument
    addAll(c);
}

And (one example of) a HashSet constructor that takes a boolean argument is described, and looks like this:

/**
 * Constructs a new, empty linked hash set.  (This package private
 * constructor is only used by LinkedHashSet.) The backing
 * HashMap instance is a LinkedHashMap with the specified initial
 * capacity and the specified load factor.
 *
 * @param      initialCapacity   the initial capacity of the hash map
 * @param      loadFactor        the load factor of the hash map
 * @param      dummy             ignored (distinguishes this
 *             constructor from other int, float constructor.)
 * @throws     IllegalArgumentException if the initial capacity is less
 *             than zero, or if the load factor is nonpositive
 */
HashSet(int initialCapacity, float loadFactor, boolean dummy) {
    map = new LinkedHashMap<E,Object>(initialCapacity, loadFactor);
}

I'm going to improve the answer by supporting partitioned tables:

find partition scheme and partition key using below scritps:

declare @partition_scheme varchar(100) = (
select distinct ps.Name AS PartitionScheme
from sys.indexes i  
join sys.partitions p ON i.object_id=p.object_id AND i.index_id=p.index_id  
join sys.partition_schemes ps on ps.data_space_id = i.data_space_id  
where i.object_id = object_id('your table name')
)
print @partition_scheme

declare @partition_column varchar(100) = (
select c.name 
from  sys.tables          t
join  sys.indexes         i 
      on(i.object_id = t.object_id 
  and i.index_id < 2)
join  sys.index_columns  ic 
  on(ic.partition_ordinal > 0 
  and ic.index_id = i.index_id and ic.object_id = t.object_id)
join  sys.columns         c 
  on(c.object_id = ic.object_id 
  and c.column_id = ic.column_id)
where t.object_id  = object_id('your table name')
)
print @partition_column

then change the generation query by adding below line at the right place:

+ IIF(@partition_scheme is null, '', 'ON [' + @partition_scheme + ']([' + @partition_column + '])')

You can use the following:

    /// <summary>
    /// Serializes an object.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="serializableObject"></param>
    /// <param name="fileName"></param>
    public void SerializeObject<T>(T serializableObject, string fileName)
    {
        if (serializableObject == null) { return; }

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
            using (MemoryStream stream = new MemoryStream())
            {
                serializer.Serialize(stream, serializableObject);
                stream.Position = 0;
                xmlDocument.Load(stream);
                xmlDocument.Save(fileName);
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }
    }


    /// <summary>
    /// Deserializes an xml file into an object list
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="fileName"></param>
    /// <returns></returns>
    public T DeSerializeObject<T>(string fileName)
    {
        if (string.IsNullOrEmpty(fileName)) { return default(T); }

        T objectOut = default(T);

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(fileName);
            string xmlString = xmlDocument.OuterXml;

            using (StringReader read = new StringReader(xmlString))
            {
                Type outType = typeof(T);

                XmlSerializer serializer = new XmlSerializer(outType);
                using (XmlReader reader = new XmlTextReader(read))
                {
                    objectOut = (T)serializer.Deserialize(reader);
                }
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }

        return objectOut;
    }

For completeness, on Apache2 on Ubuntu, you will find the default charset in charset.conf in conf-available.

Uncomment the line

AddDefaultCharset UTF-8

Try this:

this.TextBox3.Text = String.Format("{0: MM.dd.yyyy}",DateTime.Now);

Have to add this based on @Joseph's answer. If someone want to create image object:

var image = new Image();
image.onload = function(){
   console.log(image.width); // image is loaded and we have image width 
}
image.src = 'data:image/png;base64,iVBORw0K...';
document.body.appendChild(image);

(Edit 2016-10-12: Many Eclipse downloads from https://eclipse.org/downloads/eclipse-packages/ have M2Eclipse included already. As of Neon both the Java and the Java EE packages do - look for "Maven support")

Way 1: Maven Eclipse plugin installation step by step:

1. Open Eclipse IDE
2. Click Help -> Install New Software...
3. Click Add button at top right corner

4. At pop up: fill up Name as "M2Eclipse" and Location as "http://download.eclipse.org/technology/m2e/releases" or http://download.eclipse.org/technology/m2e/milestones/1.0

5. Now click OK

After that installation would be started.

Way 2: Another way to install Maven plug-in for Eclipse by "Eclipse Marketplace":

1. Open Eclipse
2. Go to Help -> Eclipse Marketplace
3. Search by Maven
4. Click "Install" button at "Maven Integration for Eclipse" section
5. Follow the instruction step by step

After successful installation do the followings in Eclipse:

1. Go to Window --> Preferences
   
2. Observe, Maven is enlisted at left panel

Finally,

1. Click on an existing project
2. Select Configure -> Convert to Maven Project

char p[3] = "hello" ? should be char p[6] = "hello" remember there is a '\0' char in the end of a "string" in C.

anyway, array in C is just a pointer to the first object of an adjust objects in the memory. the only different s are in semantics. while you can change the value of a pointer to point to a different location in the memory an array, after created, will always point to the same location.
also when using array the "new" and "delete" is automatically done for you.

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

Just found another reason why an element goes blurry when being transformed. I was using transform: translate3d(-5.5px, -18px, 0); to re-position an element once it had been loaded in, however that element became blurry.

I tried all the suggestions above but it turned out that it was due to me using a decimal value for one of the translate values. Whole numbers don't cause the blur, and the further away I went from the whole number the worse the blur became.

i.e. 5.5px blurs the element the most, 5.1px the least.

Just thought I'd chuck this here in case it helps anybody.

The correct answer IMO is git clone --mirror. This will fully backup your repo.

Git clone mirror will clone the entire repository, notes, heads, refs, etc. and is typically used to copy an entire repository to a new git server. This will pull down an all branches and everything, the entire repository.

git clone --mirror [email protected]/your-repo.git

• Normally cloning a repo does not include all branches, only Master.

• Copying the repo folder will only "copy" the branches that have been pulled in...so by default that is Master branch only or other branches you have checked-out previously.

• The Git bundle command is also not what you want: "The bundle command will package up everything that would normally be pushed over the wire with a git push command into a binary file that you can email to someone or put on a flash drive, then unbundle into another repository." (From What's the difference between git clone --mirror and git clone --bare)

Some examples of how to avoid select

Use Dim'd variables

Dim rng as Range

Set the variable to the required range. There are many ways to refer to a single-cell range:

Set rng = Range("A1")
Set rng = Cells(1, 1)
Set rng = Range("NamedRange")

Or a multi-cell range:

Set rng = Range("A1:B10")
Set rng = Range("A1", "B10")
Set rng = Range(Cells(1, 1), Cells(10, 2))
Set rng = Range("AnotherNamedRange")
Set rng = Range("A1").Resize(10, 2)

You can use the shortcut to the Evaluate method, but this is less efficient and should generally be avoided in production code.

Set rng = [A1]
Set rng = [A1:B10]

All the above examples refer to cells on the active sheet. Unless you specifically want to work only with the active sheet, it is better to Dim a Worksheet variable too:

Dim ws As Worksheet
Set ws = Worksheets("Sheet1")
Set rng = ws.Cells(1, 1)
With ws
    Set rng = .Range(.Cells(1, 1), .Cells(2, 10))
End With

If you do want to work with the ActiveSheet, for clarity it's best to be explicit. But take care, as some Worksheet methods change the active sheet.

Set rng = ActiveSheet.Range("A1")

Again, this refers to the active workbook. Unless you specifically want to work only with the ActiveWorkbook or ThisWorkbook, it is better to Dim a Workbook variable too.

Dim wb As Workbook
Set wb = Application.Workbooks("Book1")
Set rng = wb.Worksheets("Sheet1").Range("A1")

If you do want to work with the ActiveWorkbook, for clarity it's best to be explicit. But take care, as many WorkBook methods change the active book.

Set rng = ActiveWorkbook.Worksheets("Sheet1").Range("A1")

You can also use the ThisWorkbook object to refer to the book containing the running code.

Set rng = ThisWorkbook.Worksheets("Sheet1").Range("A1")

A common (bad) piece of code is to open a book, get some data then close again

This is bad:

Sub foo()
    Dim v as Variant
    Workbooks("Book1.xlsx").Sheets(1).Range("A1").Clear
    Workbooks.Open("C:\Path\To\SomeClosedBook.xlsx")
    v = ActiveWorkbook.Sheets(1).Range("A1").Value
    Workbooks("SomeAlreadyOpenBook.xlsx").Activate
    ActiveWorkbook.Sheets("SomeSheet").Range("A1").Value = v
    Workbooks(2).Activate
    ActiveWorkbook.Close()
End Sub

And it would be better like:

Sub foo()
    Dim v as Variant
    Dim wb1 as Workbook
    Dim  wb2 as Workbook
    Set wb1 = Workbooks("SomeAlreadyOpenBook.xlsx")
    Set wb2 = Workbooks.Open("C:\Path\To\SomeClosedBook.xlsx")
    v = wb2.Sheets("SomeSheet").Range("A1").Value
    wb1.Sheets("SomeOtherSheet").Range("A1").Value = v
    wb2.Close()
End Sub

Pass ranges to your Subs and Functions as Range variables:

Sub ClearRange(r as Range)
    r.ClearContents
    '....
End Sub

Sub MyMacro()
    Dim rng as Range
    Set rng = ThisWorkbook.Worksheets("SomeSheet").Range("A1:B10")
    ClearRange rng
End Sub

You should also apply Methods (such as Find and Copy) to variables:

Dim rng1 As Range
Dim rng2 As Range
Set rng1 = ThisWorkbook.Worksheets("SomeSheet").Range("A1:A10")
Set rng2 = ThisWorkbook.Worksheets("SomeSheet").Range("B1:B10")
rng1.Copy rng2

If you are looping over a range of cells it is often better (faster) to copy the range values to a variant array first and loop over that:

Dim dat As Variant
Dim rng As Range
Dim i As Long

Set rng = ThisWorkbook.Worksheets("SomeSheet").Range("A1:A10000")
dat = rng.Value  ' dat is now array (1 to 10000, 1 to 1)
for i = LBound(dat, 1) to UBound(dat, 1)
    dat(i,1) = dat(i, 1) * 10 ' Or whatever operation you need to perform
next
rng.Value = dat ' put new values back on sheet

This is a small taster for what's possible.

In case anyone else ends up here using Jupyter Notebooks, you just need

%matplotlib inline

Purpose of "%matplotlib inline"

Try this :

import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;


public class Test {

    public static void main(String[] args) {
        JFrame f = new JFrame();
        try {
            f.setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("test.jpg")))));
        } catch (IOException e) {
            e.printStackTrace();
        }
        f.pack();
        f.setVisible(true);
    }

}

By the way, this will result in the content pane not being a container. If you want to add things to it you have to subclass a JPanel and override the paintComponent method.

I think both the fastest and most concise way to do this is to use NumPy's built-in Fancy indexing. If you have an ndarray named arr, you can replace all elements >255 with a value x as follows:

arr[arr > 255] = x

I ran this on my machine with a 500 x 500 random matrix, replacing all values >0.5 with 5, and it took an average of 7.59ms.

In [1]: import numpy as np
In [2]: A = np.random.rand(500, 500)
In [3]: timeit A[A > 0.5] = 5
100 loops, best of 3: 7.59 ms per loop

The dateadd function can be used to offset to the beginning of the month. If the endDate has a day part less than startDate, it will get pushed to the previous month, thus datediff will give the correct number of months.

DATEDIFF(MONTH, DATEADD(DAY,-DAY(startDate)+1,startDate),DATEADD(DAY,-DAY(startDate)+1,endDate))

If you're using IDLE, you can use Ctrl+] to indent and Ctrl+[ to unindent.

Use datetime.datetime.strptime:

>>> import datetime
>>> date = datetime.datetime.strptime('2012-02-10', '%Y-%m-%d')
>>> date.isoweekday()
5

For me the problem was a wrong include directory. I have no idea why this caused the error with the seemingly missing lib as the include directory only contains the header files. And the library directory had the correct path set.

If you use version 26 then inside dependencies version should be 1.0.1 and 3.0.1 i.e., as follows

  androidTestImplementation 'com.android.support.test:runner:1.0.1'
  androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

If you use version 27 then inside dependencies version should be 1.0.2 and 3.0.2 i.e., as follows

  androidTestImplementation 'com.android.support.test:runner:1.0.2'
  androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

Edit: You should use the json2.js library from Douglas Crockford instead of implementing the code below. It provides some extra features and better/older browser support.

Grab the json2.js file from: https://github.com/douglascrockford/JSON-js

// implement JSON.stringify serialization
JSON.stringify = JSON.stringify || function (obj) {
    var t = typeof (obj);
    if (t != "object" || obj === null) {
        // simple data type
        if (t == "string") obj = '"'+obj+'"';
        return String(obj);
    }
    else {
        // recurse array or object
        var n, v, json = [], arr = (obj && obj.constructor == Array);
        for (n in obj) {
            v = obj[n]; t = typeof(v);
            if (t == "string") v = '"'+v+'"';
            else if (t == "object" && v !== null) v = JSON.stringify(v);
            json.push((arr ? "" : '"' + n + '":') + String(v));
        }
        return (arr ? "[" : "{") + String(json) + (arr ? "]" : "}");
    }
};

var tmp = {one: 1, two: "2"};
JSON.stringify(tmp); // '{"one":1,"two":"2"}'

Django 2.2 version now has a bulk_update method (release notes).

https://docs.djangoproject.com/en/stable/ref/models/querysets/#bulk-update

Example:

# get a pk: record dictionary of existing records
updates = YourModel.objects.filter(...).in_bulk()
....
# do something with the updates dict
....
if hasattr(YourModel.objects, 'bulk_update') and updates:
    # Use the new method
    YourModel.objects.bulk_update(updates.values(), [list the fields to update], batch_size=100)
else:
    # The old & slow way
    with transaction.atomic():
        for obj in updates.values():
            obj.save(update_fields=[list the fields to update])

The simplest solution for the problem is do standard things in your controller or you can directely put it into ApplicationController

class ApplicationController < ActionController::Base protect_from_forgery with: :exception, prepend: true end

find -L . -name "foo*"

In a few cases, I have needed the -L parameter to handle symbolic directory links. By default symbolic links are ignored. In those cases it was quite confusing as I would change directory to a sub-directory and see the file matching the pattern but find would not return the filename. Using -L solves that issue. The symbolic link options for find are -P -L -H

.NonOverflow {
    width: 200px; /* Need the width for this to work */
    overflow: hidden;
}

<div class="NonOverflow">
    Long Text
</div>

To make values empty you can do the following:

 $("#element").val('');

To get the selected value you can do:

var value = $("#element").val();

Where #element is the id of the element you wish to select.

Well, the only thing I can make it work is like so:

servers: >
    dev.example.com,
    another.example.com

@Value("${servers}")
private String[] array;

And dont forget the @Configuration above your class....

Without the "," separation, no such luck...

Works too (boot 1.5.8 versie)

servers: 
       dev.example.com,
       another.example.com

I tested this code on Nougat emulator and it worked:

In manifest add:

<application...

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths"/>
    </provider>
</application>

Create empty xml folder in res folder and past in the provider_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
 <paths xmlns:android="http://schemas.android.com/apk/res/android">
   <external-path name="external_files" path="."/>
  </paths>

Then put the next snippet into your code (for instance fragment):

File photoLcl = new File(homeDirectory + "/" + fileNameLcl);
Uri imageUriLcl = FileProvider.getUriForFile(getActivity(), 
  getActivity().getApplicationContext().getPackageName() +
    ".provider", photoLcl);
ContentResolver contentResolver = getActivity().getContentResolver();
contentResolver.delete(imageUriLcl, null, null);

For Leaflet, I'm using

    map.setView(markersLayer.getBounds().getCenter());

Use a simple:

return ((op1 ? 1 : 0) ^ (op2 ? 1 : 0));

Or use directly the InputStream of the resource using the absolute CLASSPATH path (starting with the / slash character):

getClass().getResourceAsStream("/com/path/to/file.txt");

Or relative CLASSPATH path (when the class you are writing is in the same Java package as the resource file itself, i.e. com.path.to):

getClass().getResourceAsStream("file.txt");

It is a bad practice to involve any exception throwing/handling into such a typical scenario.

Therefore a parseInt() is not nice, but a regex is an elegant solution for this, but take care of the following:
-fractions
-negative numbers
-decimal separator might differ in contries (e.g. ',' or '.')
-sometimes it is allowed to have a so called thousand separator, like a space or a comma e.g. 12,324,1000.355

To handle all the necessary cases in your application you have to be careful, but this regex covers the typical scenarios (positive/negative and fractional, separated by a dot): ^[-+]?\d*.?\d+$
For testing, I recommend regexr.com.

Having just done this myself you can do it this way:

from tkinter import Tk, Button, Frame, Entry, END

class ABC(Frame):
    def __init__(self, parent=None):
        Frame.__init__(self, parent)
        self.parent = parent
        self.pack()
        ABC.make_widgets(self)

    def make_widgets(self):
        self.parent.title("Simple Prog")

You will see the title change, and you won't get two windows. I've left my parent as master as in the Tkinter reference stuff in the python library documentation.

Just wanted to contribute a solution that I used for my app.

It is also based on the OnScrollListener interface, but I found it to have a much better scrolling performance on low-end devices, since none of the visible/total count calculations are carried out during the scroll operations.

1. Let your ListFragment or ListActivity implement OnScrollListener

2. Add the following methods to that class:

   @Override
   public void onScroll(AbsListView view, int firstVisibleItem,
           int visibleItemCount, int totalItemCount) {
       //leave this empty
   }
   
   @Override
   public void onScrollStateChanged(AbsListView listView, int scrollState) {
       if (scrollState == SCROLL_STATE_IDLE) {
           if (listView.getLastVisiblePosition() >= listView.getCount() - 1 - threshold) {
               currentPage++;
               //load more list items:
               loadElements(currentPage);
           }
       }
   }
   

   where currentPage is the page of your datasource that should be added to your list, and threshold is the number of list items (counted from the end) that should, if visible, trigger the loading process. If you set threshold to 0, for instance, the user has to scroll to the very end of the list in order to load more items.

3. (optional) As you can see, the "load-more check" is only called when the user stops scrolling. To improve usability, you may inflate and add a loading indicator to the end of the list via listView.addFooterView(yourFooterView). One example for such a footer view:

   <?xml version="1.0" encoding="utf-8"?>
   
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:id="@+id/footer_layout"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:padding="10dp" >
   
       <ProgressBar
           android:id="@+id/progressBar1"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_centerVertical="true"
           android:layout_gravity="center_vertical" />
   
       <TextView
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_centerVertical="true"
           android:layout_toRightOf="@+id/progressBar1"
           android:padding="5dp"
           android:text="@string/loading_text" />
   
   </RelativeLayout>
   

4. (optional) Finally, remove that loading indicator by calling listView.removeFooterView(yourFooterView) if there are no more items or pages.

I had the same problem because .htaccess has incorrect settings:

RewriteEngine on
RewriteRule !.(js|gif|jpg|png|css)$ index.php

I solved this by modifying the file:

RewriteEngine on
RewriteRule !.(js|gif|jpg|png|css|eot|svg|ttf|woff|woff2|map)$ index.php

If all steps (in existing answers) dont work , Just close eclipse and again open eclipse .

You can also have a look at MyBatis (www.mybatis.org) . It helps you write SQL statements outside your java code and maps the sql results into your java objects among other things.

For properties for which css transition will affect, can use transitionend event, example for z-index:

$(".observed-element").on("webkitTransitionEnd transitionend", function(e) {_x000D_
  console.log("end", e);_x000D_
  alert("z-index changed");_x000D_
});_x000D_
_x000D_
$(".changeButton").on("click", function() {_x000D_
  console.log("click");_x000D_
  document.querySelector(".observed-element").style.zIndex = (Math.random() * 1000) | 0;_x000D_
});

.observed-element {_x000D_
  transition: z-index 1ms;_x000D_
  -webkit-transition: z-index 1ms;_x000D_
}_x000D_
div {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid;_x000D_
  position: absolute;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<button class="changeButton">change z-index</button>_x000D_
<div class="observed-element"></div>

first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

I had two problems with using Acrobat Reader for this task.

1. The command line API is not officially supported, so it could change or be removed without warning.
2. Send a print command to Reader loads up the GUI, with seemingly no way to prevent it. I needed the process to be transparent to the user.

I stumbled across this blog, that suggests using Foxit Reader. Foxit Reader is free, the API is almost identical to Acrobat Reader, but crucially is documented and does not load the GUI for print jobs.

A word of warning, don't just click through the install process without paying attention, it tries to install unrelated software as well. Why are software vendors still doing this???

You can just loop over your array:

var doc = { /* your json */ };

function getById(arr, id) {
    for (var d = 0, len = arr.length; d < len; d += 1) {
        if (arr[d].id === id) {
            return arr[d];
        }
    }
}

var doc_id_2 = getById(doc.results, 2);

If you don't want to write this messy loops, you can consider using underscore.js or Lo-Dash (example in the latter):

var doc_id_2 = _.filter(doc.results, {id: 2})[0]

There are two problems. As in the question, select-string needs to operate on the output string, which can be had from "out-string". Also, select-string doesn't operate linewise on strings that are piped to it. Here is a generic solution

(alias|out-string) -split "`n" | select-string Write 

My solution was to make sure I selected a version of Ruby for that repo.

Example: chruby 2.2.2 or rvm use 2.2.2

? bundle install
zsh: command not found: bundle

? ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

### Notice the system Ruby version isn't included in chruby

? chruby
  ruby-1.9.3-p551
  ruby-2.1.2
  ruby-2.2.1

### Select a version via your version manager

? chruby 1.9.3

### Ensure your version manager properly selects a version (*)

? chruby
 * ruby-1.9.3-p551
   ruby-2.1.2
   ruby-2.2.1

? bundle install

This question actually have more deep nature and good understanding of the multithreading concepts in general will provide you insight about this topic. In fact there is no any language or any operating system which provide you facilities for asynchronous abruptly thread termination without warning to not use them. And all these execution environments strongly advise developer or even require build multithreading applications on the base of cooperative or synchronous thread termination. The reason for this common decisions and advices is that all they are built on the base of the same general multithreading model.

Let's compare multiprocessing and multithreading concepts to better understand advantages and limitations of the second one.

Multiprocessing assumes splitting of the entire execution environment into set of completely isolated processes controlled by the operating system. Process incorporates and isolates execution environment state including local memory of the process and data inside it and all system resources like files, sockets, synchronization objects. Isolation is a critically important characteristic of the process, because it limits the faults propagation by the process borders. In other words, no one process can affects the consistency of any another process in the system. The same is true for the process behaviour but in the less restricted and more blur way. In such environment any process can be killed in any "arbitrary" moment, because firstly each process is isolated, secondly, operating system have full knowledges about all resources used by process and can release all of them without leaking, and finally process will be killed by OS not really in arbitrary moment, but in the number of well defined points where the state of the process is well known.

In contrast, multithreading assumes running multiple threads in the same process. But all this threads are share the same isolation box and there is no any operating system control of the internal state of the process. As a result any thread is able to change global process state as well as corrupt it. At the same moment the points in which the state of the thread is well known to be safe to kill a thread completely depends on the application logic and are not known neither for operating system nor for programming language runtime. As a result thread termination at the arbitrary moment means killing it at arbitrary point of its execution path and can easily lead to the process-wide data corruption, memory and handles leakage, threads leakage and spinlocks and other intra-process synchronization primitives leaved in the closed state preventing other threads in doing progress.

Due to this the common approach is to force developers to implement synchronous or cooperative thread termination, where the one thread can request other thread termination and other thread in well-defined point can check this request and start the shutdown procedure from the well-defined state with releasing of all global system-wide resources and local process-wide resources in the safe and consistent way.

Important behavior changes between old and new style classes

• super added
• MRO changed (explained below)
• descriptors added
• new style class objects cannot be raised unless derived from Exception (example below)
• __slots__ added

MRO (Method Resolution Order) changed

It was mentioned in other answers, but here goes a concrete example of the difference between classic MRO and C3 MRO (used in new style classes).

The question is the order in which attributes (which include methods and member variables) are searched for in multiple inheritance.

Classic classes do a depth-first search from left to right. Stop on the first match. They do not have the __mro__ attribute.

class C: i = 0
class C1(C): pass
class C2(C): i = 2
class C12(C1, C2): pass
class C21(C2, C1): pass

assert C12().i == 0
assert C21().i == 2

try:
    C12.__mro__
except AttributeError:
    pass
else:
    assert False

New-style classes MRO is more complicated to synthesize in a single English sentence. It is explained in detail here. One of its properties is that a base class is only searched for once all its derived classes have been. They have the __mro__ attribute which shows the search order.

class C(object): i = 0
class C1(C): pass
class C2(C): i = 2
class C12(C1, C2): pass
class C21(C2, C1): pass

assert C12().i == 2
assert C21().i == 2

assert C12.__mro__ == (C12, C1, C2, C, object)
assert C21.__mro__ == (C21, C2, C1, C, object)

New style class objects cannot be raised unless derived from Exception

Around Python 2.5 many classes could be raised, and around Python 2.6 this was removed. On Python 2.7.3:

# OK, old:
class Old: pass
try:
    raise Old()
except Old:
    pass
else:
    assert False

# TypeError, new not derived from `Exception`.
class New(object): pass
try:
    raise New()
except TypeError:
    pass
else:
    assert False

# OK, derived from `Exception`.
class New(Exception): pass
try:
    raise New()
except New:
    pass
else:
    assert False

# `'str'` is a new style object, so you can't raise it:
try:
    raise 'str'
except TypeError:
    pass
else:
    assert False

Steps for BitBucket:

if you dont want to generate new key, SKIP ssh-keygen

ssh-keygen -t rsa 

Copy the public key to clipboard:

clip < ~/.ssh/id_rsa.pub

Login to Bit Bucket: Go to View Profile -> Settings -> SSH Keys (In Security tab) Click Add Key, Paste the key in the box, add a descriptive title

Go back to Git Bash :

ssh-add -l

You should get :

2048 SHA256:5zabdekjjjaalajafjLIa3Gl/k832A /c/Users/username/.ssh/id_rsa (RSA)

Now: git pull should work

One of the problems with starting your line with non-breaking spaces is that if your line is long enough to wrap, then when it spills onto a second line the first character of the overflow line with start hard left instead of starting under the first character of the line above it.

If your system allows you to mix HTML in with your markdown, a cheep and cheerful way of getting an indent is like this:

<ul>
My indented text goes here, and it can be long and wrap if you like.
And you can have multiple lines if you want.
</ul>

Semantically within your HTML it is nonsense (a UL section without any LI items), but all browsers I have used just happily indent what's between those tags.

You pass them in just like you're thinking, and in your script, you get them from the array @ARGV. Like so:

my $numArgs = $#ARGV + 1;
print "thanks, you gave me $numArgs command-line arguments.\n";

foreach my $argnum (0 .. $#ARGV) {

   print "$ARGV[$argnum]\n";

}

From here.

It's called a Favicon, have a read.

<link rel="shortcut icon" href="http://www.example.com/myicon.ico"/>

You can use this neat tool to generate cross-browser compatible Favicons.

Contents are shallow copied.

So if the original dict contains a list or another dictionary, modifying one them in the original or its shallow copy will modify them (the list or the dict) in the other.

If you want to explore options of communicating between components and feel like it is getting harder and harder, then you might consider adopting a good design pattern: Flux.

It is simply a collection of rules that defines how you store and mutate application wide state, and use that state to render components.

There are many Flux implementations, and Facebook's official implementation is one of them. Although it is considered the one that contains most boilerplate code, but it is easier to understand since most of the things are explicit.

Some of Other alternatives are flummox fluxxor fluxible and redux.

Truncating the table wont be possible even if you disable the foreign keys.so you can use delete command to remove all the records from the table,but be aware if you are using delete command for a table which consists of millions of records then your package will be slow and your transaction log size will increase and it may fill up your valuable disk space.

If you drop the constraints it may happen that you will fill up your table with unclean data and when you try to recreate the constraints it may not allow you to as it will give errors. so make sure that if you drop the constraints,you are loading data which are correctly related to each other and satisfy the constraint relations which you are going to recreate.

so please carefully think the pros and cons of each method and use it according to your requirements

def post(self,request):
        serializer = ProductSerializer(data=request.DATA, files=request.FILES)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)

Try using this attribute, for example for password min length:

[StringLength(100, ErrorMessage = "???????????? ????? ?????? 20 ????????", MinimumLength = User.PasswordMinLength)]

See the String method trim() - https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/Trim

var myString = '  bunch    of <br> string data with<p>trailing</p> and leading space   ';
myString = myString.trim();
// or myString = String.trim(myString);

Edit

As noted in other comments, it is possible to use the regex approach. The trim method is effectively just an alias for a regex:

if(!String.prototype.trim) {  
  String.prototype.trim = function () {  
    return this.replace(/^\s+|\s+$/g,'');  
  };  
} 

... this will inject the method into the native prototype for those browsers who are still swimming in the shallow end of the pool.

If the other answers fail, importing it as

import moment from 'moment/moment.js'

may work.

I didn't find any with cURL so I wrote a wrapper around node-libcurl and can be found at https://www.npmjs.com/package/vps-rest-client.

To make a POST is like so:

var host = 'https://api.budgetvm.com/v2/dns/record';
var key = 'some___key';
var domain_id = 'some___id';

var rest = require('vps-rest-client');
var client = rest.createClient(key, {
  verbose: false
});

var post = {
  domain: domain_id,
  record: 'test.example.net',
  type: 'A',
  content: '111.111.111.111'
};

client.post(host, post).then(function(resp) {
  console.info(resp);

  if (resp.success === true) {
    // some action
  }
  client.close();
}).catch((err) => console.info(err));

scala> d("a")= "ABC"

Add new key-value:

scala> d(100)= "new element"

Check the updated map:

scala> d
res123: scala.collection.mutable.Map[Any,Any] = Map(2 -> test, 100 -> new element, a -> ABC, 1 -> 234)

UITableView has a tableHeaderView property. Set that to whatever view you want up there.

Use a new UIView as a container, add a text label and an image view to that new UIView, then set tableHeaderView to the new view.

For example, in a UITableViewController:

-(void)viewDidLoad
{
     // ...
     UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     [headerView addSubview:imageView];
     UILabel *labelView = [[UILabel alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     [headerView addSubview:labelView];
     self.tableView.tableHeaderView = headerView;
     [imageView release];
     [labelView release];
     [headerView release];
     // ...
} 

A stateless system can be seen as a box [black? ;)] where at any point in time the value of the output(s) depends only on the value of the input(s) [after a certain processing time]

A stateful system instead can be seen as a box where at any point in time the value of the output(s) depends on the value of the input(s) and of an internal state, so basicaly a stateful system is like a state machine with "memory" as the same set of input(s) value can generate different output(s) depending on the previous input(s) received by the system.

From the parallel programming point of view, a stateless system, if properly implemented, can be executed by multiple threads/tasks at the same time without any concurrency issue [as an example think of a reentrant function] A stateful system will requires that multiple threads of execution access and update the internal state of the system in an exclusive way, hence there will be a need for a serialization [synchronization] point.

It should be emphasized that since Python 3.6, you only need the standard lib to get a timezone aware datetime object that represents local time (the setting of your OS). Using astimezone()

import datetime

datetime.datetime(2010, 12, 25, 10, 59).astimezone()
# e.g.
# datetime.datetime(2010, 12, 25, 10, 59, tzinfo=datetime.timezone(datetime.timedelta(seconds=3600), 'Mitteleuropäische Zeit'))

datetime.datetime(2010, 12, 25, 12, 59).astimezone().isoformat()
# e.g.
# '2010-12-25T12:59:00+01:00'

# I'm on CET/CEST

(see @johnchen902's comment). Note there's a small caveat though, astimezone(None) gives aware datetime, unaware of DST.

I'm late to the party, but if you want to do this to an arbitrary element using only CSS, without messing around with positioning, overlay divs etc., you can use an inset box shadow:

box-shadow: inset 0px 0px 0 2000px rgba(0,0,0,0.5);

This will work on any element smaller than 4000 pixels long or wide.

Actually what you are searching is: Optional.map. Your code would then look like:

object.map(o -> "result" /* or your function */)
      .orElseThrow(MyCustomException::new);

I would rather omit passing the Optional if you can. In the end you gain nothing using an Optional here. A slightly other variant:

public String getString(Object yourObject) {
  if (Objects.isNull(yourObject)) { // or use requireNonNull instead if NullPointerException suffices
     throw new MyCustomException();
  }
  String result = ...
  // your string mapping function
  return result;
}

If you already have the Optional-object due to another call, I would still recommend you to use the map-method, instead of isPresent, etc. for the single reason, that I find it more readable (clearly a subjective decision ;-)).

I've used for my Wordpress blog this as .htaccess. It converts http://www.blah.example/asad, http://blah.example/asad, http://www.blah.example2/asad etc, to http://blah.example/asad Thanks to all other answers I figured this out.

Easiest and Simplest method of solving this problem is using re

import re

search_list = ['one', 'two', 'there']
long_string = 'some one long two phrase three'
if re.compile('|'.join(search_list),re.IGNORECASE).search(long_string): #re.IGNORECASE is used to ignore case
    # Do Something if word is present
else:
    # Do Something else if word is not present

If you can turn the stored procedure into a function that returns a table, then you can use cross-apply.

For example, say you have a table of customers, and you want to compute the sum of their orders, you would create a function that took a CustomerID and returned the sum.

And you could do this:

SELECT CustomerID, CustomerSum.Total

FROM Customers
CROSS APPLY ufn_ComputeCustomerTotal(Customers.CustomerID) AS CustomerSum

Where the function would look like:

CREATE FUNCTION ComputeCustomerTotal
(
    @CustomerID INT
)
RETURNS TABLE
AS
RETURN
(
    SELECT SUM(CustomerOrder.Amount) AS Total FROM CustomerOrder WHERE CustomerID = @CustomerID
)

Obviously, the example above could be done without a user defined function in a single query.

The drawback is that functions are very limited - many of the features of a stored procedure are not available in a user-defined function, and converting a stored procedure to a function does not always work.

The solutions here didn't work for me as I'm styling react components.

What worked though for the sidebar was

.sidebar{
position: sticky;
top: 0;
}

Hope this helps someone.

Look at snprintf or, if GNU extensions are OK, asprintf (which will allocate memory for you).

To style for many smartphones with smaller screens, you could write:

@media screen and (max-width:480px) { … } 

To block older browsers from seeing an iPhone or Android phone style sheet, you could write:

@media only screen and (max-width: 480px;) { … }

Let's make this clearer. We use include every time we want to express the fact that the existence of one case depends on the existence of another.

EXAMPLES:

A user can do shopping online only after he has logged in his account. In other words, he can't do any shopping until he has logged in his account.

A user can't download from a site before the material had been uploaded. So, I can't download if nothing has been uploaded.

Do you get it?

It's about conditioned consequence. I can't do this if previously I didn't do that.

At least, I think this is the right way we use Include. I tend to think the example with Laptop and warranty from right above is the most convincing!

i forgot to add below line to my HTML code after i add problem has resolved.

If your issue is with linked servers, you need to look at a few things.

First, your users need to have delegation enabled and if the only thing that's changed, it'l likely they do. Otherwise you can uncheck the "Account is sensitive and cannot be delegated" checkbox is the user properties in AD.

Second, your service account(s) must be trusted for delegation. Since you recently changed your service account I suspect this is the culprit. (http://technet.microsoft.com/en-us/library/cc739474(v=ws.10).aspx)

You mentioned that you might have some SPN issues, so be sure to set the SPN for both endpoints, otherwise you will not be able to see the delegation tab in AD. Also make sure you're in advanced view in "Active Directory Users and Computers."

If you still do not see the delegation tab, even after correcting your SPN, make sure your domain not in 2000 mode. If it is, you can "raise domain function level."

At this point, you can now mark the account as trusted for delegation:

In the details pane, right-click the user you want to be trusted for delegation, and click Properties.

Click the Delegation tab, select the Account is trusted for delegation check box, and then click OK.

Finally you will also need to set all the machines as trusted for delegation.

Once you've done this, reconnect to your sql server and test your liked servers. They should work.

Java seems to have a bias towards using double for computations nonetheless:

Case in point the program I wrote earlier today, the methods didn't work when I used float, but now work great when I substituted float with double (in the NetBeans IDE):

package palettedos;
import java.util.*;

class Palettedos{
    private static Scanner Z = new Scanner(System.in);
    public static final double pi = 3.142;

    public static void main(String[]args){
        Palettedos A = new Palettedos();
        System.out.println("Enter the base and height of the triangle respectively");
        int base = Z.nextInt();
        int height = Z.nextInt();
        System.out.println("Enter the radius of the circle");
        int radius = Z.nextInt();
        System.out.println("Enter the length of the square");
        long length = Z.nextInt();
        double tArea = A.calculateArea(base, height);
        double cArea = A.calculateArea(radius);
        long sqArea = A.calculateArea(length);
        System.out.println("The area of the triangle is\t" + tArea);
        System.out.println("The area of the circle is\t" + cArea);
        System.out.println("The area of the square is\t" + sqArea);
    }

    double calculateArea(int base, int height){
        double triArea = 0.5*base*height;
        return triArea;
    }

    double calculateArea(int radius){
        double circArea = pi*radius*radius;
        return circArea;
    }

    long calculateArea(long length){
        long squaArea = length*length;
        return squaArea;
    }
}

I opened this thread looking for a quick solution to a simple question, but I found that the answers here were either not helpful or overly complicated. The best way to get the last 5 chars of a string is, in fact, to use the Right() method. Here is a simple example:

Dim sMyString, sLast5 As String

sMyString = "I will be going to school in 2011!"
sLast5 = Right(sMyString, - 5)
MsgBox("sLast5 = " & sLast5)

If you're getting an error then there is probably something wrong with your syntax. Also, with the Right() method you don't need to worry much about going over or under the string length. In my example you could type in 10000 instead of 5 and it would just MsgBox the whole string, or if sMyString was NULL or "", the message box would just pop up with nothing.

Use setMaxDate().

For example, replace return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay) statement with something like this:

    DatePickerDialog dialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
    dialog.getDatePicker().setMaxDate(new Date().getTime());
    return dialog;

The most upvoted answer above is weird in a way that it simply clears the Clipboard and then gets the content (which is then empty). One could clear the clipboard to be sure that some clipboard content type like "formated text" does not "cover" your plain text content you want to save in the clipboard.

The following piece of code replaces all newlines in the clipboard by spaces, then removes all double spaces and finally saves the content back to the clipboard:

import win32clipboard

win32clipboard.OpenClipboard()
c = win32clipboard.GetClipboardData()
win32clipboard.EmptyClipboard()
c = c.replace('\n', ' ')
c = c.replace('\r', ' ')
while c.find('  ') != -1:
    c = c.replace('  ', ' ')
win32clipboard.SetClipboardText(c)
win32clipboard.CloseClipboard()

First you need to determine the revision ID of the last known commit. You can use HEAD^ or HEAD~{1} if you know you need to reverse exactly one commit.

git reset --hard <revision_id_of_last_known_good_commit>
git push --force

I tried the iptables PREROUTING REDIRECT method. In older kernels it seems this type of rule wasn't supported for IPv6. But apparently it is now supported in ip6tables v1.4.18 and Linux kernel v3.8.

I also found that PREROUTING REDIRECT doesn't work for connections initiated within the machine. To work for conections from the local machine, add an OUTPUT rule also — see iptables port redirect not working for localhost. E.g. something like:

iptables -t nat -I OUTPUT -o lo -p tcp --dport 80 -j REDIRECT --to-port 8080

I also found that PREROUTING REDIRECT also affects forwarded packets. That is, if the machine is also forwarding packets between interfaces (e.g. if it's acting as a Wi-Fi access point connected to an Ethernet network), then the iptables rule will also catch connected clients' connections to Internet destinations, and redirect them to the machine. That's not what I wanted—I only wanted to redirect connections that were directed to the machine itself. I found I can make it only affect packets addressed to the box, by adding -m addrtype --dst-type LOCAL. E.g. something like:

iptables -A PREROUTING -t nat -p tcp --dport 80 -m addrtype --dst-type LOCAL -j REDIRECT --to-port 8080

One other possibility is to use TCP port forwarding. E.g. using socat:

socat TCP4-LISTEN:www,reuseaddr,fork TCP4:localhost:8080

However one disadvantage with that method is, the application that is listening on port 8080 then doesn't know the source address of incoming connections (e.g. for logging or other identification purposes).
