This might help you out:

Sub SelectFolder()
    Dim diaFolder As FileDialog
    Dim Fname As String

    Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
    diaFolder.AllowMultiSelect = False
    diaFolder.Show

    Fname = diaFolder.SelectedItems(1)

    ActiveSheet.Range("B9") = Fname

End Sub

Since it took me a while to figure it out, I thought it would be helpful to post my solution using Java 7+ ZipFileSystem

 openZip(runFile);

 addToZip(filepath); //loop construct;  

 zipfs.close();

 private void openZip(File runFile) throws IOException {
    Map<String, String> env = new HashMap<>();
    env.put("create", "true");
    env.put("encoding", "UTF-8");
    Files.deleteIfExists(runFile.toPath());
    zipfs = FileSystems.newFileSystem(URI.create("jar:" + runFile.toURI().toString()), env);    
 }

 private void addToZip(String filename) throws IOException {
    Path externalTxtFile = Paths.get(filename).toAbsolutePath();
    Path pathInZipfile = zipfs.getPath(filename.substring(filename.lastIndexOf("results"))); //all files to be stored have a common base folder, results/ in my case
    if (Files.isDirectory(externalTxtFile)) {
        Files.createDirectories(pathInZipfile);
        try (DirectoryStream<Path> ds = Files.newDirectoryStream(externalTxtFile)) {
            for (Path child : ds) {
                addToZip(child.normalize().toString()); //recursive call
            }
        }
    } else {
        // copy file to zip file
        Files.copy(externalTxtFile, pathInZipfile, StandardCopyOption.REPLACE_EXISTING);            
    }
 }

For me, the most easy way is:

#include <boost/timer.hpp>

boost::timer t;
double duration;

t.restart();
/* DO SOMETHING HERE... */
duration = t.elapsed();

t.restart();
/* DO OTHER STUFF HERE... */
duration = t.elapsed();

using this piece of code you don't have to do the classic end - start.

Enjoy your favorite approach.

try setting the body style to:

body { position:relative;}

it worked for me

I'm starting to learn how to code with Swift and was trying to solve this too, this is what I came up with on Swift's playground:

// Code
var x = 1
var y = 2
var lowX = 1
var lowY = 1
var highX = 3
var highY = 3


if (x, y) >= (lowX, lowY) && (x, y) <= (highX, highY ) {
    print("inside")
} else {
    print("not inside")
}

It prints inside

If you can't use LIMIT or LIMIT is not an option for your query tool. You can use "ROWNUM" instead, but you will need a sub query:

SELECT FIELD_1, ALIAS1
FROM(SELECT FIELD_1, COUNT(FIELD_1) ALIAS1
    FROM TABLENAME
    GROUP BY FIELD_1
    ORDER BY COUNT(FIELD_1) DESC)
WHERE ROWNUM = 1

You need to use overflow option like below:

.nav{
    max-height: 300px;
    overflow-y: scroll; 
}

Change the height according to amount of items you need to show

Compound checking:

   if (thing.foo && thing.foo.bar) {
      ... thing.foor.bar exists;
   }

Use a shell script:

#!/bin/bash
# myscript
FOO=bar
somecommand someargs | somecommand2

> ./myscript

Solution with FocusScope doesn't work for me. I found another:

import 'package:flutter/services.dart';

SystemChannels.textInput.invokeMethod('TextInput.hide');

It solved my problem.

    public List<dynamic> MyProperty { get; set; }
}

or

public class ClassName

This maybe what you're looking for:

awk 'BEGIN {FS=" ";} {printf "'\''%s'\'' ", $1}'

That is, with '\'' you close the opening ', then print a literal ' by escaping it and finally open the ' again.

Use this method and pass your array in parameter

Collections.shuffle(arrayList);

This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.

You can now use arraylist which is shuffled.

To prevent users from resizing, set the FormBoderStyle to Fixed3D or FixedDialog from properties window or from code

frmYour.BorderStyle = System.WinForms.FormBorderStyle.Fixed3D

And set the WindowState property to Maximized, set the MaximizeBox and MinimizeBox properties to false.

To prevent the user from moving around, override WndProc

Protected Overrides Sub WndProc(ByRef m As Message)
        Const WM_NCLBUTTONDOWN As Integer = 161
        Const WM_SYSCOMMAND As Integer = 274
        Const HTCAPTION As Integer = 2
        Const SC_MOVE As Integer = 61456

        If (m.Msg = WM_SYSCOMMAND) And (m.WParam.ToInt32() = SC_MOVE) Then
            Return
        End If

        If (m.Msg = WM_NCLBUTTONDOWN) And (m.WParam.ToInt32() = HTCAPTION) Then
            Return
        End If

        MyBase.WndProc(m)

You're using the ajax function incorrectly. Since it's synchronous it'll return the data inline like so:

var remote = $.ajax({
    type: "GET",
    url: remote_url,
    async: false
}).responseText;

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

When you run selenium WebDriver, the WebDriver opens a remote server in your computer's local host. Now, this server, called the Selenium Server, is used to interpret your code into actions to run or "drive" the instance of a real browser known as either chromebrowser, ie broser, ff browser, etc.

So, the Selenium Server can interact with different browser properties and hence it has many "capabilities".

Now what capabilities do you desire? Consider a scenario where you are validating if files have been downloaded properly in your app but, however, you do not have a desktop automation tool. In the case where you click the download link and a desktop pop up shows up to ask where to save and/or if you want to download. Your next route to bypass that would be to suppress that pop up. How? Desired Capabilities.

There are other such examples. In summary, Selenium Server can do a lot, use Desired Capabilities to tailor it to your need.

The other answers do not seem to touch on a key aspect here, and that is you make no mention of requiring supporting a web browser as a client. Most of the limitations of plain HTTP above are assuming you would be working with browser/ JS implementations.

The HTTP protocol is fully capable of full-duplex communication; it is legal to have a client perform a POST with a chunked encoding transfer, and a server to return a response with a chunked-encoding body. This would remove the header overhead to just at init time.

So if all you're looking for is full-duplex, control both client and server, and are not interested in extra framing/features of WebSockets, then I would argue that HTTP is a simpler approach with lower latency/CPU (although the latency would really only differ in microseconds or less for either).

public static void main(String[] args) {
    int[] arr1 = {2,4,6,8,10,999};
    int[] arr2 = {1,3,5,9,100,1001};

    int[] arr3 = new int[arr1.length + arr2.length];

    int temp = 0;

    for (int i = 0; i < (arr3.length); i++) {
        if(temp == arr2.length){
            arr3[i] = arr1[i-temp];
        }
        else if (((i-temp)<(arr1.length)) && (arr1[i-temp] < arr2[temp])){
                arr3[i] = arr1[i-temp];
        }
        else{
            arr3[i] = arr2[temp];
            temp++;
        }
    }

    for (int i : arr3) {
        System.out.print(i + ", ");
    }
}

Output is :

1, 2, 3, 4, 5, 6, 8, 9, 10, 100, 999, 1001,

Just in case, if someone is looking for a hack to somehow make the scrollbar invisible in firefox(79.0).

Here's a solution that successfully works for Chrome, IE, Safari, and makes the scrollbar transparent in Firefox. None of the above worked for firefox(79.0) in truly hiding the scrollbar.

Please if anyone finds a way to do it without changing the color, it will be very helpful. Pls comment below.

.scrollhost::-webkit-scrollbar {
  display: none;
}

.scrollhost ::-moz-scrollbar {
  display: none;
 
}
 
.scrollhost {
  overflow: auto;
  -ms-overflow-style: none;
  scrollbar-color: transparent transparent; /*just hides the scrollbar for firefox */
}

You can use the -B option.

Try pip uninstall jupyter_core. Details below:

I ran into a similar issue when my jupyter notebook only showed Python 2 notebook. (no Python 3 notebook)

I tried to uninstall jupyter by pip unistall jupyter, pi3 uninstall jupyter, and the suggested pip-autoremove jupyter -y.

Nothing worked. I ran which jupyter, and got /home/ankit/.local/bin/jupyter

The file /home/ankit/.local/bin/jupyter was just a simple python code:

#!/usr/bin/python3

# -*- coding: utf-8 -*-
import re
import sys

from jupyter_core.command import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

Tried to uninstall the module jupyter_core by pip uninstall jupyter_core and it worked.

Reinstalled jupyter with pip3 install jupyter and everything was back to normal.

You need to use the target selector.

Here is a fiddle with another example: http://jsfiddle.net/YYPKM/3/

Try using rowMeans:

z$mean=rowMeans(z[,c("x", "y")], na.rm=TRUE)

  w x  y mean
1 5 1  1    1
2 6 2  2    2
3 7 3  3    3
4 8 4 NA    4

Using ls:

  ls -LR

from 'man ls':

   -L, --dereference
          when showing file information for a symbolic link, show informa-
          tion  for  the file the link references rather than for the link
          itself

Or, using find:

find -L .

From the find manpage:

-L     Follow symbolic links.

If you find you want to only follow a few symbolic links (like maybe just the toplevel ones you mentioned), you should look at the -H option, which only follows symlinks that you pass to it on the commandline.

I tried everything mentioned, but with no success. The method which I used for Swift 3.0 :

extension UIAlertController {
    func show() {
        present(animated: true, completion: nil)
    }

    func present(animated: Bool, completion: (() -> Void)?) {
        if var topController = UIApplication.shared.keyWindow?.rootViewController {
            while let presentedViewController = topController.presentedViewController {
                topController = presentedViewController
            }
            topController.present(self, animated: animated, completion: completion)
        }
    }
}

That is a pretty standard use case for apply():

R> vec <- 1:10
R> DF <- data.frame(start=c(1,3,5,7), end=c(2,6,7,9))
R> DF$newcol <- apply(DF,1,function(row) mean(vec[ row[1] : row[2] ] ))
R> DF
  start end newcol
1     1   2    1.5
2     3   6    4.5
3     5   7    6.0
4     7   9    8.0

You can also use plyr if you prefer but here is no real need to go beyond functions from base R.

Quoting Chris: "... when your program quits, any daemon threads are killed automatically.". I think that sums it up. You should be careful when you use them as they abruptly terminate when main program executes to completion.

Setting a width of 100% is the full width of the div it's in, not the original full-sized image. There is no way to do that without JavaScript or some other scripting language that can measure the image. If you can have a fixed width or fixed height of the div (like 200px wide) then it shouldn't be too hard to give the image a range to fill. But if you put a 20x20 pixel image in a 200x300 pixel box it will still be distorted.

Writing from phone, but curvycorners is really good, since it adds it's own borders only if browser doesn't support it by default. In other words, browsers which already support some CSS3 will use their own system to provide corners.
https://code.google.com/p/curvycorners/

You cannot execute php functions from JavaScript.

PHP runs on the server before the browser sees it. PHP outputs HTML and JavaScript.

When the browser reads the html and javascript it executes it.

The :not pseudo-class is not supported by IE. I'd got for something like this instead:

.registration_form_right input[type="text"],
.registration_form_right input[type="password"],
.registration_form_right input[type="submit"],
.registration_form_right input[type="button"] {
  ...
}

Some duplication there, but it's a small price to pay for higher compatibility.

While xrange is faster than range in most circumstances, the difference in performance is pretty minimal. The little program below compares iterating over a range and an xrange:

import timeit
# Try various list sizes.
for list_len in [1, 10, 100, 1000, 10000, 100000, 1000000]:
  # Time doing a range and an xrange.
  rtime = timeit.timeit('a=0;\nfor n in range(%d): a += n'%list_len, number=1000)
  xrtime = timeit.timeit('a=0;\nfor n in xrange(%d): a += n'%list_len, number=1000)
  # Print the result
  print "Loop list of len %d: range=%.4f, xrange=%.4f"%(list_len, rtime, xrtime)

The results below shows that xrange is indeed faster, but not enough to sweat over.

Loop list of len 1: range=0.0003, xrange=0.0003
Loop list of len 10: range=0.0013, xrange=0.0011
Loop list of len 100: range=0.0068, xrange=0.0034
Loop list of len 1000: range=0.0609, xrange=0.0438
Loop list of len 10000: range=0.5527, xrange=0.5266
Loop list of len 100000: range=10.1666, xrange=7.8481
Loop list of len 1000000: range=168.3425, xrange=155.8719

So by all means use xrange, but unless you're on a constrained hardware, don't worry too much about it.

Youcan either send a Ajax request to server or use window.location to that url.

I think what you're asking about is how to create responsive spacing between rows or col-xx-xx classes.

You can definitely do this with the col-xx-offset-xx class:

<div class="col-xs-4">
</div>

<div class="col-xs-7 col-xs-offset-1">
</div>

As for adding margin or padding directly to elements, there are some simple ways to do this depending on your element. You can use btn-lg or label-lg or well-lg. If you're ever wondering, how can i give this alittle padding. Try adding the primary class name + lg or sm or md depending on your size needs:

<button class="btn btn-success btn-lg btn-block">Big Button w/ Display: Block</button>

You could add a method to String to make it more semantic:

String.metaClass.getNotBlank = { !delegate.allWhitespace }

which let's you do:

groovy:000> foo = ''
===> 
groovy:000> foo.notBlank
===> false
groovy:000> foo = 'foo'
===> foo
groovy:000> foo.notBlank
===> true

If you have some estimation about the distance between the 2 strings 'abc' and 'efg' you are looking for, you might use:

grep -r . -e 'abc' -A num1 -B num2 | grep 'efg'

That way, the first grep will return the line with the 'abc' plus #num1 lines after it, and #num2 lines after it, and the second grep will sift through all of those to get the 'efg'. Then you'll know at which files they appear together.

You can only return from inside a function and not from a loop.

It seems like your return should be outside the while loop, and your complete code should be inside a function.

def func():
    N = int(input("enter a positive integer:"))
    counter = 1
    while (N > 0):
        counter = counter * N
        N -= 1
    return counter  # de-indent this 4 spaces to the left.

print func()

And if those codes are not inside a function, then you don't need a return at all. Just print the value of counter outside the while loop.

You can use regular expressions for extracting the number from string. Lets check it. Suppose this is the string mixing text and numbers 'stack12345overflow569'. This one should work:

select regexp_replace('stack12345overflow569', '[[:alpha:]]|_') as numbers from dual;

which will return "12345569".

also you can use this one:

select regexp_replace('stack12345overflow569', '[^0-9]', '') as numbers,
       regexp_replace('Stack12345OverFlow569', '[^a-z and ^A-Z]', '') as characters
from dual

which will return "12345569" for numbers and "StackOverFlow" for characters.

Try this:

@section Scripts 
{
    Scripts.Render("~/bundles/jqueryval")  // <- without ampersand at the begin
}

Another Note:

    string path = @"H:\\MOVIES\\Battel SHIP\\done-battleship-cd1.avi"; 
    string hh = string.Format("\"{0}\"", path);
    Process.Start(@"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe ", hh + " ,--play");

The real value of hh as passed will be "H:\MOVIES\Battel SHIP\done-battleship-cd1.avi".

When needing double double literals use: @"H:\MOVIES\Battel SHIP\done-battleship-cd1.avi"; Instead of: @"H:\MOVIESBattel SHIP\done-battleship-cd1.avi"; Because the first literals is for the path name and then the second literals are for the double quotation marks

I have the current latest version of MySQL: 8.0.20

So my table name is visit, my column name is curdate.

alter table visit modify curdate date not null default (current_date);

This writes the default date value with no timestamp.

$ source_file_filename_no_ext=${source_file%.*}
$ echo ${source_file_filename_no_ext##*/}

Headings are normally bold-faced; that has been turned off for this demonstration of size correspondence. MSIE and Opera interpret these sizes the same, but note that Gecko browsers and Chrome interpret Heading 6 as 11 pixels instead of 10 pixels/font size 1, and Heading 3 as 19 pixels instead of 18 pixels/font size 4 (though it's difficult to tell the difference even in a direct comparison and impossible in use). It seems Gecko also limits text to no smaller than 10 pixels.

For anyone seeking a solution that does not use the command line: ctrl+shift+t

I'm not sure what the difference is but add the include path to the project as well as the target.

Buffer is an area of memory used to temporarily store data while it's being moved from one place to another.

Cache is a temporary storage area used to store frequently accessed data for rapid access. Once the data is stored in the cache, future use can be done by accessing the cached copy rather than re-fetching the original data, so that the average access time is shorter.

Note: buffer and cache can be allocated on disk as well

This thread seems to answer your question : simultaneous-read-write-a-file

Basically, what you need is to declare two FileStream, one for read operations, the other for write operations. Writer Filestream needs to open your file in 'Append' mode.

Hi For jQuery You can only use like this

Use async and type="text/javascript" only

The following example and explanation are from the book Professional JavaScript for Web Developers 2nd Edition by Nicholas Zakas. This is the answer I was looking for so I thought it would be helpful to add it here.

(function () {
    var name = '';
    Person = function (value) {
        name = value;
    };
    Person.prototype.getName = function () {
        return name;
    };
    Person.prototype.setName = function (value) {
        name = value;
    };
}());
var person1 = new Person('Nate');
console.log(person1.getName()); // Nate
person1.setName('James');
console.log(person1.getName()); // James
person1.name = 'Mark';
console.log(person1.name); // Mark
console.log(person1.getName()); // James
var person2 = new Person('Danielle');
console.log(person1.getName()); // Danielle
console.log(person2.getName()); // Danielle

The Person constructor in this example has access to the private variable name, as do the getName() and setName() methods. Using this pattern, the name variable becomes static and will be used among all instances. This means calling setName() on one instance affects all other instances. Calling setName() or creating a new Person instance sets the name variable to a new value. This causes all instances to return the same value.

If there's any chance that your datetimes aren't strict calendar dates, you should consider using enddate exclusion comparisons... This will prevent you from missing any requests created during the date of Jan 31.

DateTime now = DateTime.Now;
DateTime thisMonth = new DateTime(now.Year, now.Month, 1);
DateTime lastMonth = thisMonth.AddMonths(-1);

var RequestIds = rdc.request
  .Where(r => lastMonth <= r.dteCreated)
  .Where(r => r.dteCreated < thisMonth)
  .Select(r => r.intRequestId);

Static method never allows a non-static method call directly.

Reason: Static method belongs to its class only, and to nay object or any instance.

So, whenever you try to access any non-static method from static method inside the same class: you will receive:

"An object reference is required for the non-static field, method or property".

Solution: Just declare a reference like:

public class <classname>
{
static method()
{
   new <classname>.non-static();
}

non-static method()
{

}


}

A simple return statement will 'stop' or return the function; in precise terms, it 'returns' function execution to the point at which the function was called - the function is terminated without further action.

That means you could have a number of places throughout your function where it might return. Like this:

def player():
    # do something here
    check_winner_variable = check_winner()  # check something 
    if check_winner_variable == '1': 
        return
    second_test_variable = second_test()
    if second_test_variable == '1': 
        return
       
    # let the computer do something
    computer()

One way you do this is set a counter and if number exceeds the certain number return false. easy as this.

var mybutton_counter=0;
$("#mybutton").on('click', function(e){
    if (mybutton_counter>0){return false;} //you can set the number to any
    //your call
     mybutton_counter++; //incremental
});

make sure, if statement is on top of your call.

You can try this:

:backup move C:\FilesToBeBackedUp\*.* E:\BackupPlace\ timeout 36000 goto backup

If that doesn't work try to replace "timeout" with sleep. Ik this post is over a year old, just helping anyone with the same problem.

If you want to add a product into the array you can use:

$item['product'] = $product;

One easy solution is to use overflow values other than visible to make the text flex basis width reset as expected.

1. Here with value auto the text wraps as expected and the article content does not overflow main container.

2. Also, the article flex value must either have a auto basis AND be able to shrink, OR, only grow AND explicit 0 basis

main, aside, article {_x000D_
  margin: 10px;_x000D_
  border: solid 1px #000;_x000D_

The better solutions, when possible are:

• Replicate your data (using log-replication) to a reporting database.
• Use SAN snapshots and mount a consistent version of the DB
• Use a database which has a better fundamental transaction isolation level

The SNAPSHOT transaction isolation level was created because MS was losing sales to Oracle. Oracle uses undo/redo logs to avoid this problem. Postgres uses MVCC. In the future MS's Heckaton will use MVCC, but that's years away from being production ready.

For the ones that want to create a calculated column in a table to store the age:

CASE WHEN DateOfBirth< DATEADD(YEAR, (DATEPART(YEAR, GETDATE()) - DATEPART(YEAR, DateOfBirth))*-1, GETDATE()) 
     THEN DATEPART(YEAR, GETDATE()) - DATEPART(YEAR, DateOfBirth)
     ELSE DATEPART(YEAR, GETDATE()) - DATEPART(YEAR, DateOfBirth) -1 END

Rhino is what you are looking for.

Rhino is an open-source implementation of JavaScript written entirely in Java. It is typically embedded into Java applications to provide scripting to end users.

Update: Now Nashorn, which is more performant JavaScript Engine for Java, is available with jdk8.

Echo the session object as json. I like json because I have a browser extension that nicely formats json.

session_start();
echo json_encode($_SESSION);

In practice, Beans are just objects which are handy to use. Serializing them means to be able easily to persist them (store in a form that is easily recovered).

Typical uses of Beans in real world:

• simple reusable objects POJO (Plain Old Java Objects)
• visual objects
• Spring uses Beans for objects to handle (for instance, User object that needs to be serialized in session)
• EJB (Enterprise Java Beans), more complex objects, like JSF Beans (JSF is old quite outdated technology) or JSP Beans

So in fact, Beans are just a convention / standard to expect something from a Java object that it would behave (serialization) and give some ways to change it (setters for properties) in a certain way.

How to use them, is just your invention, but most common cases I enlisted above.

m2eclipse has moved from sonatype to eclipse.

The correct update site is http://download.eclipse.org/technology/m2e/releases/

If this is not working, one possibility is you have an older version of Eclipse (< 3.6). The other - if you see timeout related errors - could be that you are behind a proxy server.

new Date('2012.08.10').getTime() / 1000

Check the JavaScript Date documentation.

The results of years of my meddling with vim are all here.

If your sole purpose is to convert a 1d array X to a 2d array just do:

X = np.reshape(X,(1, X.size))

As already mentioned continue will skip processing the code below it and until the end of the loop. Then, you are moved to the loop's condition and run the next iteration if this condition still holds (or if there is a flag, to the denoted loop's condition).

It must be highlighted that in the case of do - while you are moved to the condition at the bottom after a continue, not at the beginning of the loop.

This is why a lot of people fail to correctly answer what the following code will generate.

    Random r = new Random();
    Set<Integer> aSet= new HashSet<Integer>();
    int anInt;
    do {
        anInt = r.nextInt(10);
        if (anInt % 2 == 0)
            continue;
        System.out.println(anInt);
    } while (aSet.add(anInt));
    System.out.println(aSet);

*If your answer is that aSet will contain odd numbers only 100%... you are wrong!

In Windows - for Fiddler say - using environment variables:

set http_proxy=http://127.0.0.1:8888
set https_proxy=http://127.0.0.1:8888

One issue with REPLACE will be where city names contain the district name. You can use something like.

SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM   dbo.tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004' 

For me this error appeared immediatey after I changed the user's home directory by

sudo usermod -d var/www/html username

It can also happen because of lack of proper permission to authorized_key file in ~/.ssh. Make sure the permission of this file is 0600 and permission of ~/.ssh is 700.

Your E class doesn't have a member of type struct X, you've just defined a nested struct X in there (i.e. you've defined a new type).

Try:

#include <iostream>

class E
{
    public: 
    struct X { int v; };
    X x; // an instance of `struct X`
};

int main(){

    E object;
    object.x.v = 1;

    return 0;
}

It was already mentioned, but thought I could add to using touch

If you touch all the source files to be compiled, the touch command changes the timestamps of a file to the system time the touch command was executed.

The source file timstamp is what make uses to "know" a file has changed, and needs to be re-compiled

For example: If the project was a c++ project, then do touch *.cpp, then run make again, and make should recompile the entire project.

"df.values" returns a numpy array. This does not preserve the data types. An integer might be converted to a float.

df.iterrows() returns a series which also does not guarantee to preserve the data types. See: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.iterrows.html

The code below converts to a list of list and preserves the data types:

rows = [list(row) for row in df.itertuples()]

Here's an option if you need to escape multiple %'s in a string with some already escaped.

(?:[^%]|^)(?:(%%)+|)(%)(?:[^%])

To sanitise the message before passing it to String.format, you can use the following

Pattern p = Pattern.compile("(?:[^%]|^)(?:(%%)+|)(%)(?:[^%])");
Matcher m1 = p.matcher(log);

StringBuffer buf = new StringBuffer();
while (m1.find())
    m1.appendReplacement(buf, log.substring(m1.start(), m1.start(2)) + "%%" + log.substring(m1.end(2), m1.end()));

// Return the sanitised message
String escapedString = m1.appendTail(buf).toString();

This works with any number of formatting characters, so it will replace % with %%, %%% with %%%%, %%%%% with %%%%%% etc.

It will leave any already escaped characters alone (e.g. %%, %%%% etc.)

The difference between those will depend largely on what browser you are currently referring to. Each one implements these properties differently, or not at all. Quirksmode has great documentation regarding browser differences in regards to W3C standards like the DOM and JavaScript Events.

You can use Array.from to convert collection to array, which is way cleaner than Array.prototype.forEach.call:

Array.from(document.getElementsByClassName("myclass")).forEach(
    function(element, index, array) {
        // do stuff
    }
);

In older browsers which don't support Array.from, you need to use something like Babel.

ES6 also adds this syntax:

[...document.getElementsByClassName("myclass")].forEach(
    (element, index, array) => {
        // do stuff
    }
);

Rest destructuring with ... works on all array-like objects, not only arrays themselves, then good old array syntax is used to construct an array from the values.

While the alternative function querySelectorAll (which kinda makes getElementsByClassName obsolete) returns a collection which does have forEach natively, other methods like map or filter are missing, so this syntax is still useful:

[...document.querySelectorAll(".myclass")].map(
    (element, index, array) => {
        // do stuff
    }
);

[...document.querySelectorAll(".myclass")].map(element => element.innerHTML);

Try Like This: For SQL SERVER 2008+

SELECT c.name AS ColName, t.name AS TableName
FROM sys.columns c
    JOIN sys.tables t ON c.object_id = t.object_id
WHERE c.name LIKE '%MyColumnaName%'

Or

SELECT COLUMN_NAME, TABLE_NAME 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE COLUMN_NAME LIKE '%MyName%'

Or Something Like This:

SELECT name  
FROM sys.tables 
WHERE OBJECT_ID IN ( SELECT id 
              FROM syscolumns 
              WHERE name like '%COlName%' )

Here's another minimal way to do it in CSS that works even in older browsers that do not support :nth-child and the like selectors: http://jsfiddle.net/3wZWt/.

HTML:

<table>
    <tr>
        <th>From</th>
        <th>Subject</th>
        <th>Date</th>
    </tr>
    <tr>
        <td>Dmitriy</td>
        <td>Learning CSS</td>
        <td>7/5/2014</td>
    </tr>
</table>

CSS:

table {
    border-collapse: collapse;
    width: 100%;
}

tr > * {
    border: 1px solid #000;
}

tr > th + th {
    width: 70%;
}

tr > th + th + th {
    width: 15%;
}

I had a similar problem which I solved by changing the Port Settings in the port driver (located in Ports in device manager) to fit the device I was using.

For me it was that wrong Bits per second value was set.

A different user name is the common cause for this, Nuget downloads everything into: "C:\Users\USER_NAME\source\repos" and if you had the project previously setup on a different user name the .csproj file may still contain that old user name there, simply open it and do a search replace for "C:\Users\_OLD_USER_NAME\source\repos" to "C:\Users\NEW_USER_NAME\source\repos".

In a generic sense, a "hook" is something that will let you, a programmer, view and/or interact with and/or change something that's already going on in a system/program.

For example, the Drupal CMS provides developers with hooks that let them take additional action after a "content node" is created. If a developer doesn't implement a hook, the node is created per normal. If a developer implements a hook, they can have some additional code run whenever a node is created. This code could do anything, including rolling back and/or altering the original action. It could also do something unrelated to the node creation entirely.

A callback could be thought of as a specific kind of hook. By implementing callback functionality into a system, that system is letting you call some additional code after an action has completed. However, hooking (as a generic term) is not limited to callbacks.

Another example. Sometimes Web Developers will refer to class names and/or IDs on elements as hooks. That's because by placing the ID/class name on an element, they can then use Javascript to modify that element, or "hook in" to the page document. (this is stretching the meaning, but it is commonly used and worth mentioning)

<ul>
    <li ng-repeat="item in items | filter:keyword as filteredItems">
        ...
    </li>
    <li ng-if="filteredItems.length===0">
        No items found
    </li>
</ul>

This is similar to @Konrad 'ktoso' Malawski but slightly easier to remember.

Tested with Angular 1.4

If it helps anyone, I found that the problem was I already had an android:onClick event in my layout file (which I inflated for the ListView rows). This was superseding the onItemClick event.

Assume that you have multiple properties you want to convert.

public class OrigType{
    public string Prop1A {get;set;}
    public string Prop1B {get;set;}
}

public class TargetType{
    public string Prop2A {get;set;}
    public string Prop2B {get;set;}
}

var list1 = new List<OrigType>();
var list2 = new List<TargetType>();

list1.ConvertAll(x => new OrigType { Prop2A = x.Prop1A, Prop2B = x.Prop1B })

The solutions so far are all quite complicated. The idiomatic solution should doubtless be:

String.Join(",", x.Cast(Of String)().ToArray())

There's no need for fancy acrobatics in new framework versions. Supposing a not-so-modern version, the following would be easiest:

Console.WriteLine(String.Join(",", CType(x.ToArray(GetType(String)), String())))

mspmsp's second solution is a nice approach as well but it's not working because it misses the AddressOf keyword. Also, Convert.ToString is rather inefficient (lots of unnecessary internal evaluations) and the Convert class is generally not very cleanly designed. I tend to avoid it, especially since it's completely redundant.

They're simply different schemes for representing Unicode characters.

Both are variable-length - UTF-16 uses 2 bytes for all characters in the basic multilingual plane (BMP) which contains most characters in common use.

UTF-8 uses between 1 and 3 bytes for characters in the BMP, up to 4 for characters in the current Unicode range of U+0000 to U+1FFFFF, and is extensible up to U+7FFFFFFF if that ever becomes necessary... but notably all ASCII characters are represented in a single byte each.

For the purposes of a message digest it won't matter which of these you pick, so long as everyone who tries to recreate the digest uses the same option.

See this page for more about UTF-8 and Unicode.

(Note that all Java characters are UTF-16 code points within the BMP; to represent characters above U+FFFF you need to use surrogate pairs in Java.)

Static libraries do not link with other static libraries. The only way to do this is to use your librarian/archiver tool (for example ar on Linux) to create a single new static library by concatenating the multiple libraries.

Edit: In response to your update, the only way I know to select only the symbols that are required is to manually create the library from the subset of the .o files that contain them. This is difficult, time consuming and error prone. I'm not aware of any tools to help do this (not to say they don't exist), but it would make quite an interesting project to produce one.

You can use offsets to make a column appear centered, just use an offset equal to half of the remaining size of the row, in your case I would suggest using col-lg-4 with col-lg-offset-4, that's (12-4)/2.

<div class="row">
    <div class="col-lg-4 col-lg-offset-4">
        <div class="input-group">
            <input type="text" class="form-control" /> 
            <span class="input-group-btn">
                <button class="btn btn-default" type="button">Go!</button>
            </span>
        </div><!-- /input-group -->
    </div><!-- /.col-lg-4 -->
</div><!-- /.row -->

Demo fiddle

Note that this technique only works for even column sizes (.col-X-2, .col-X-4, col-X-6, etc...), if you want to support any size you can use margin: 0 auto; but you need to remove the float from the element too, I recommend a custom CSS class like the following:

.col-centered{
    margin: 0 auto;
    float: none;
}

Demo fiddle

This is an example using the Expr() Class - I needed this too some days ago and it took me some time to find out what is the exact syntax and way of usage:

/**
 * fetches Products that are more expansive than the given price
 * 
 * @param int $price
 * @return array
 */
public function findProductsExpensiveThan($price)
{
  $em = $this->getEntityManager();
  $qb = $em->createQueryBuilder();

  $q  = $qb->select(array('p'))
           ->from('YourProductBundle:Product', 'p')
           ->where(
             $qb->expr()->gt('p.price', $price)
           )
           ->orderBy('p.price', 'DESC')
           ->getQuery();

  return $q->getResult();
}

The answer from @KM is good as far as it goes but fails to fully follow up on one of his early bits of advice;

..., ignore compact code, ignore worrying about repeating code, ...

If you are looking to achieve the best performance then you should write a bespoke query for each possible combination of optional criteria. This might sound extreme, and if you have a lot of optional criteria then it might be, but performance is often a trade-off between effort and results. In practice, there might be a common set of parameter combinations that can be targeted with bespoke queries, then a generic query (as per the other answers) for all other combinations.

CREATE PROCEDURE spDoSearch
    @FirstName varchar(25) = null,
    @LastName varchar(25) = null,
    @Title varchar(25) = null
AS
BEGIN

    IF (@FirstName IS NOT NULL AND @LastName IS NULL AND @Title IS NULL)
        -- Search by first name only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            FirstName = @FirstName

    ELSE IF (@FirstName IS NULL AND @LastName IS NOT NULL AND @Title IS NULL)
        -- Search by last name only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            LastName = @LastName

    ELSE IF (@FirstName IS NULL AND @LastName IS NULL AND @Title IS NOT NULL)
        -- Search by title only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            Title = @Title

    ELSE IF (@FirstName IS NOT NULL AND @LastName IS NOT NULL AND @Title IS NULL)
        -- Search by first and last name
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            FirstName = @FirstName
            AND LastName = @LastName

    ELSE
        -- Search by any other combination
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
                (@FirstName IS NULL OR (FirstName = @FirstName))
            AND (@LastName  IS NULL OR (LastName  = @LastName ))
            AND (@Title     IS NULL OR (Title     = @Title    ))

END

The advantage of this approach is that in the common cases handled by bespoke queries the query is as efficient as it can be - there's no impact by the unsupplied criteria. Also, indexes and other performance enhancements can be targeted at specific bespoke queries rather than trying to satisfy all possible situations.

I ran into the same problem since I had changed my global path of npm packages before.

Here's how I fixed it :

When I installed nodemon using : npm install nodemon -g --save , my path for the global npm packages was not present in the PATH variable .

If you just add it to the $PATH variable it will get fixed.

Edit the ~/.bashrc file in your home folder and add this line :-

export PATH=$PATH:~/npm

Here "npm" is the path to my global npm packages . Replace it with the global path in your system

restorecon command works as below :

restorecon -v -R /var/www/html/

If you prefer, you can set these options via the commmand line (instead of editing the config file) like so:

  $ git config branch.master.remote origin
  $ git config branch.master.merge refs/heads/master

Or, if you're like me, and want this to be the default across all of your projects, including those you might work on in the future, then add it as a global config setting:

  $ git config --global branch.master.remote origin
  $ git config --global branch.master.merge refs/heads/master

moment("01:15:00 PM", "h:mm:ss A").format("HH:mm:ss")
**o/p: 13:15:00 **

it will give convert 24 hrs format to 12 hrs format.

Adding to answer by @Sasxa,

In Injectables you can use class normally that is putting initial code in constructor instead of using ngOnInit(), it works fine.

File file = new File("src/test/resources/validation.txt");
DiskFileItem fileItem = new DiskFileItem("file", "text/plain", false, file.getName(), (int) file.length() , file.getParentFile());
fileItem.getOutputStream();
MultipartFile multipartFile = new CommonsMultipartFile(fileItem);

You need the

fileItem.getOutputStream();

because it will throw NPE otherwise.

I found the solution.

dim bExists
ssig="Unable to open registry key"

set wshShell= Wscript.CreateObject("WScript.Shell")
strKey = "HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Digest\"
on error resume next
present = WshShell.RegRead(strKey)
if err.number<>0 then
    if right(strKey,1)="\" then    'strKey is a registry key
        if instr(1,err.description,ssig,1)<>0 then
            bExists=true
        else
            bExists=false
        end if

autocomplete="off" this should fix the issue for all modern browsers.

<form name="form1" id="form1" method="post" autocomplete="off"
   action="http://www.example.com/form.cgi">
  [...]
</form>

In current versions of Gecko browsers, the autocomplete attribute works perfectly. For earlier versions, going back to Netscape 6.2, it worked with the exception for forms with "Address" and "Name"

Update

In some cases, the browser will keep suggesting autocompletion values even if the autocomplete attribute is set to off. This unexpected behavior can be quite puzzling for developers. The trick to really forcing the no-autocompletion is to assign a random string to the attribute, for example:

autocomplete="nope"

Since this random value is not a valid one, the browser will give up.

Documetation

First approach refers:

    std::sort(numbers.begin(), numbers.end(), std::greater<>());

You may use the first approach because of getting more efficiency than second.
The first approach's time complexity less than second one.

Let us say we have to sort a list of objects in ascending order based on a particular property, in this example lets say we have to sort based on the "name" property, then below is the required code :

var list_Objects = [{"name"="Bob"},{"name"="Jay"},{"name"="Abhi"}];
Console.log(list_Objects);   //[{"name"="Bob"},{"name"="Jay"},{"name"="Abhi"}]
    list_Objects.sort(function(a,b){
        return a["name"].localeCompare(b["name"]); 
    });
Console.log(list_Objects);  //[{"name"="Abhi"},{"name"="Bob"},{"name"="Jay"}]

It is explained pretty well here: Display a view from another controller in ASP.NET MVC

To quote @Womp:
By default, ASP.NET MVC checks first in \Views\[Controller_Dir]\, but after that, if it doesn't find the view, it checks in \Views\Shared.

ASP MVC's idea is "convention over configuration" which means moving the view to the shared folder is the way to go in such cases.

The following should do the trick - Only SqlServer

Alter TRIGGER Catagory_Master_Date_update ON Catagory_Master AFTER delete,Update
AS
BEGIN

SET NOCOUNT ON;

Declare @id int
DECLARE @cDate as DateTime
    set @cDate =(select Getdate())

select @id=deleted.Catagory_id from deleted
print @cDate

execute dbo.psp_Update_Category @id

END

Alter PROCEDURE dbo.psp_Update_Category
@id int
AS
BEGIN

DECLARE @cDate as DateTime
    set @cDate =(select Getdate())
    --Update Catagory_Master Set Modify_date=''+@cDate+'' Where Catagory_ID=@id   --@UserID
    Insert into Catagory_Master (Catagory_id,Catagory_Name) values(12,'Testing11')
END 

Here is a little code. It works (for me) at any subsequent html code change of the WebBrowser control. You may adapt it to your specific needs.

    static public void SetWebBrowserHtml(WebBrowser Browser, string HtmlText)
    {
        if (Browser != null)
        {
            if (string.IsNullOrWhiteSpace(HtmlText))
            {
                // Putting a div inside body forces control to use div instead of P (paragraph)
                // when the user presses the enter button
                HtmlText = 
                        @"<html>
                    <head>
                    <meta http-equiv=""Content-Type"" content=""text/html; charset=UTF-8"" />
                    </head>
                      <div></div>
                    <body>
                    </body>
                    </html>";
            }

            if (Browser.Document == null)
            {
                Browser.Navigate("about:blank");

                //Wait for document to finish loading
                while (Browser.ReadyState != WebBrowserReadyState.Complete)
                {

I've used EasyCharts in the past and it lived up to it's name. It's not as powerful as JFreeChart, but the JAR for EasyCharts is much smaller than for JFreeChart.

You can do the following:

df =DataFrame({'a':[1,2,3,4],'b':[2,4,6,8]})

df['x']=df.a + df.b
df['y']=df.a - df.b

create column title whatever order you want in this way:

column_titles = ['x','y','a','b']

df.reindex(columns=column_titles)

This will give you desired output

From the Python glossary:

It’s important to keep in mind that all packages are modules, but not all modules are packages. Or put another way, packages are just a special kind of module. Specifically, any module that contains a __path__ attribute is considered a package.

Python files with a dash in the name, like my-file.py, cannot be imported with a simple import statement. Code-wise, import my-file is the same as import my - file which will raise an exception. Such files are better characterized as scripts whereas importable files are modules.

str.replace(/^.+?\"|^.|\".+/, '');

This is sometimes bad to use when you wanna select what else to remove between "" and you cannot use it more than twice in one string. All it does is select whatever is not in between "" and replace it with nothing.

Even for me it is a bit confusing, but ill try to explain it. ^.+? (not anything OPTIONAL) till first " then | Or/stop (still researching what it really means) till/at ^. has selected nothing until before the 2nd " using (| stop/at). And select all that comes after with .+.

Scenario:

I have master updating and my branch updating, I want my branch to keep track of master with rebasing, to keep all history tracked properly, let's call my branch Mybranch

Solution:

git checkout master    
git pull --rebase    
git checkout Mybranch    
git rebase master
git push -f origin Mybranch

• need to resolve all conflicts with git mergetool &, git rebase --continue, git rebase --skip, git add -u, according to situation and git hints, till all is solved

(correction to last stage, in courtesy of Tzachi Cohen, using "-f" forces git to "update history" at server)

now branch should be aligned with master and rebased, also with remote updated, so at git log there are no "behind" or "ahead", just need to remove all local conflict *.orig files to keep folder "clean"

On Windows install http://chocolatey.org/ then

choco install python

Open a new cmd-window with the updated PATH. Next, do

choco install pip

After that you can

pip install pyside
pip install ipython

Microsoft has listened to the cry for supporting installers (MSI) in Visual Studio and released the Visual Studio Installer Projects Extension. You can now create installers in Visual Studio 2013; download the extension here from the visualstudiogallery.

Universal solution

I have found some issues with the dot separator in the previous top voted answers. I have designed a universal solution where you can use whatever you want as a thousand separator without modifying the locale. I know it's not the most elegant solution, but it gets the job done. Feel free to improve it !

def format_integer(number, thousand_separator='.'):
    def reverse(string):
        string = "".join(reversed(string))
        return string

    s = reverse(str(number))
    count = 0
    result = ''
    for char in s:
        count = count + 1
        if count % 3 == 0:
            if len(s) == count:
                result = char + result
            else:
                result = thousand_separator + char + result
        else:
            result = char + result
    return result


print(format_integer(50))
# 50
print(format_integer(500))
# 500
print(format_integer(50000))
# 50.000
print(format_integer(50000000))
# 50.000.000

This fixed it for me. It sets the owner found under the 'files' section of the database properties window, and is as scripted by management studio.

Here are some:

• Use all processor cores by starting a multiple-compile job (make -j2 is a good example).
• Turn off or lower optimizations (for example, GCC is much faster with -O1 than -O2 or -O3).
• Use precompiled headers.

I can't comment, but in reference to: Angular 2 optional route parameter

an update for Angular 6:

import {map} from "rxjs/operators"

constructor(route: ActivatedRoute) {
  let paramId = route.params.pipe(map(p => p.id));

  if (paramId) {
    ...
  }
}

The PyPA recommended tool for installing and managing Python packages is pip. pip is included with Python 3.4 (PEP 453), but for older versions here's how to install it (on Windows, using Python 3.3):

Download https://bootstrap.pypa.io/get-pip.py

>c:\Python33\python.exe get-pip.py
Downloading/unpacking pip
Downloading/unpacking setuptools
Installing collected packages: pip, setuptools
Successfully installed pip setuptools
Cleaning up...

Sample usage:

>c:\Python33\Scripts\pip.exe install pymysql
Downloading/unpacking pymysql
Installing collected packages: pymysql
Successfully installed pymysql
Cleaning up...

In your case it would be this (it appears that pip caches independent of Python version):

The magic of autoloading stuff

I think the option controlling the folders from which autoloading stuff gets done has been sufficiently covered in other answers. However, in case someone else is having trouble stuff loaded though they've had their autoload paths modified as required, then this answer tries to explain what is the magic behind this autoload thing.

So when it comes to loading stuff from subdirectories there's a gotcha or a convention you should be aware. Sometimes the Ruby/Rails magic (this time mostly Rails) can make it difficult to understand why something is happening. Any module declared in the autoload paths will only be loaded if the module name corresponds to the parent directory name. So in case you try to put into lib/my_stuff/bar.rb something like:

module Foo
  class Bar
  end
end

It will not be loaded automagically. Then again if you rename the parent dir to foo thus hosting your module at path: lib/foo/bar.rb. It will be there for you. Another option is to name the file you want autoloaded by the module name. Obviously there can only be one file by that name then. In case you need to split your stuff into many files you could of course use that one file to require other files, but I don't recommend that, because then when on development mode and you modify those other files then Rails is unable to automagically reload them for you. But if you really want you could have one file by the module name that then specifies the actual files required to use the module. So you could have two files: lib/my_stuff/bar.rb and lib/my_stuff/foo.rb and the former being the same as above and the latter containing a single line: require "bar" and that would work just the same.

P.S. I feel compelled to add one more important thing. As of lately, whenever I want to have something in the lib directory that needs to get autoloaded, I tend to start thinking that if this is something that I'm actually developing specifically for this project (which it usually is, it might some day turn into a "static" snippet of code used in many projects or a git submodule, etc.. in which case it definitely should be in the lib folder) then perhaps its place is not in the lib folder at all. Perhaps it should be in a subfolder under the app folder· I have a feeling that this is the new rails way of doing things. Obviously, the same magic is in work wherever in you autoload paths you put your stuff in so it's good to these things. Anyway, this is just my thoughts on the subject. You are free to disagree. :)

UPDATE: About the type of magic..

As severin pointed out in his comment, the core "autoload a module mechanism" sure is part of Ruby, but the autoload paths stuff isn't. You don't need Rails to do autoload :Foo, File.join(Rails.root, "lib", "my_stuff", "bar"). And when you would try to reference the module Foo for the first time then it would be loaded for you. However what Rails does is it gives us a way to try and load stuff automagically from registered folders and this has been implemented in such a way that it needs to assume something about the naming conventions. If it had not been implemented like that, then every time you reference something that's not currently loaded it would have to go through all of the files in all of the autoload folders and check if any of them contains what you were trying to reference. This in turn would defeat the idea of autoloading and autoreloading. However, with these conventions in place it can deduct from the module/class your trying to load where that might be defined and just load that.

1. Add your JDK's /bin folder to the PATH environmental variable. You can do this under System settings > Environmental variables, or via CLI:

   set PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_80\bin
   

2. Close and reopen your CLI window

For completion, in ES6 we've got classes (supported at the time of writing this only by latest browsers, but available in Babel, TypeScript and other transpilers)

class Foo {
  constructor(){
    this.a = 5;
    this.b = 6;
    this.c = this.a + this.b;
  }  
}

const foo = new Foo();

If you wish a full domain origin, you can use this:

document.location.origin

And if you wish to get only the domain, use can you just this:

document.location.hostname

But you have other options, take a look at the properties in:

document.location

            LEAVE one_by_one;
         END IF;
      END LOOP one_by_one;

this procedure will insert all dates from the beginning of the year till now, just substitue the days of the "start" and "end", and you are ready to go!

(For the record and before the thread disappears on the msdn forums) You can't disable the warning (at least under VS2010) because it is on the list of the warnings that can't be disabled (so /wd4099 will not work), but what you can do instead is patch link.exe (usually C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\link.exe) to remove it from said list . Sounds like a jackhammer, i know. It works though.

For instance, if you want to remove the warning for 4099, open link.exe with an hex editor, goto line 15A0 which reads 03 10 (little endian for 4099) and replace it with FF 00 (which does not exist.)

See Bi Rico's answer for the general Eclipse case.

For anybody - like me - who lands here because you have lots of windows and you're struggling to close them all, just killing python can be effective, depending on your circumstances. It probably works under almost any circumstances - including with Eclipse.

I just spawned 60 plots from emacs (I prefer that to eclipse) and then I thought my script had exited. Running close('all') in my ipython window did not work for me because the plots did not come from ipython, so I resorted to looking for running python processes.

When I killed the interpreter running the script, then all 60 plots were closed - e.g.,

$ ps aux | grep python
rsage    11665  0.1  0.6 649904 109692 ?       SNl  10:54   0:03 /usr/bin/python3 /usr/bin/update-manager --no-update --no-focus-on-map

$ kill 12410

Note that I did not kill my ipython/pylab, nor did I kill the update manager (killing the update manager is probably a bad idea)...

Are you talking about automated unit/integration tests or manual tests?

For the former, my rule of thumb (based on measurements) is 40-50% added to development time i.e. if developing a use case takes 10 days (before an QA and serious bugfixing happens), writing good tests takes another 4 to 5 days - though this should best happen before and during development, not afterwards.

UPDATED Sep. 13, 2019:

I use <br class=big> to make an oversized line break, when I need one. Until today, I styled it like this:

br.big {line-height:190%;vertical-align:top}

(The vertical-align:top was only needed for IE and Edge.)

That worked in all the major browsers that I tried: Chrome, Firefox, Opera, Brave, PaleMoon, Edge, and IE11.

However, it recently stopped working in Chrome-based browsers: my "big" line breaks turned into normal-sized line breaks.

(I don't know exactly when they broke it. As of Sep 12, 2019 it still works in my out-of-date Chromium Portable 55.0.2883.11, but it's broken in Opera 63.0.3368.71 and Chrome 76.0.3809.132 (both Windows and Android).)

After some trial and error, I ended up with the following substitute, which works in the current versions of all those browsers:

br.big {display:block; content:""; margin-top:0.5em; line-height:190%; vertical-align:top;}

Notes:

line-height:190% works in everything except recent versions of Chrome-based browsers.

vertical-align:top is needed for IE and Edge (in combination with line-height:190%), to get the extra space to come after the preceding line, where it belongs, rather than partially before and partially after.

display:block;content:"";margin-top:0.5em works in Chrome, Opera & Firefox, but not Edge & IE.

An alternative (simpler) way of adding a bit of extra vertical space after a <br> tag, if you don't mind editing the HTML, is with something like this. It works fine in all browsers:

<span style="vertical-align:-37%"> </span><br>

(You can, of course, adjust the "-37%" as needed, for a larger or smaller gap.) Here's a demo page which includes some other variations on the theme:

https://burtonsys.com/a_little_extra_vertical_space_for_br_tag.html



May 28, 2020:

I've updated the demo page; it now demonstrates all of the above techniques:

https://burtonsys.com/a_little_extra_vertical_space_for_br_tag.html

This worked for me:

File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)

clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.

Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.

then in:

Run >> Edit Configurations

Add this line to VM Options:

--module-path /path/to/JavaFX/lib --add-modules=javafx.controls

(oh and don't forget to set the SDK)

I had the same problem minutes ago. I've mentioned changing the 'deployment target' fixed my problem.

A rect can't contain a text element. Instead transform a g element with the location of text and rectangle, then append both the rectangle and the text to it:

var bar = chart.selectAll("g")
    .data(data)
  .enter().append("g")
    .attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });

bar.append("rect")
    .attr("width", x)
    .attr("height", barHeight - 1);

bar.append("text")
    .attr("x", function(d) { return x(d) - 3; })
    .attr("y", barHeight / 2)
    .attr("dy", ".35em")
    .text(function(d) { return d; });

Multi-line labels are also a little tricky, you might want to check out this wrap function.

302 is temporary redirect, which is generated by the server whereas 307 is internal redirect response generated by the browser. Internal redirect means that redirect is done automatically by browser internally, basically the browser alters the entered url from http to https in get request by itself before making the request so request for unsecured connection is never made to the internet. Whether browser will alter the url to https or not depends upon the hsts preload list that comes preinstalled with the browser. You can also add any site which support https to the list by entering the domain in the hsts preload list of your own browser which is at chrome://net-internals/#hsts.One more thing website domains can be added by their owners to preload list by filling up the form at https://hstspreload.org/ so that it comes preinstalled in browsers for every user even though I mention you can do particularly for yourself also.

Let me explain with an example:
I made a get request to http://www.pentesteracademy.com which supports only https and I don't have that domain in my hsts preload list on my browser as site owner has not registered for it to come with preinstalled hsts preload list.
GET request for unsecure version of the site is redirected to secure version(see http header named location for that in response in above image).
Now I add the site to my own browser preload list by adding its domain in Add hsts domain form at chrome://net-internals/#hsts, which modifies my personal preload list on my chrome browser.Be sure to select include subdomains for STS option there.
Let's see the request and response for the same website now after adding it to hsts preload list.

you can see the internal redirect 307 there in response headers, actually this response is generated by your browser not by server.
Also HSTS preload list can help prevent users reach the unsecure version of site as 302 redirect are prone to mitm attacks.
Hope I somewhat helped you understand more about redirects.

Update C# 7

Yes: Source

switch(shape)

    case Circle c:
        WriteLine($"circle with radius {c.Radius}");
        break;
    case Rectangle s when (s.Length == s.Height):

    default:
        WriteLine("<unknown shape>");
        break;

No.

http://blogs.msdn.com/b/peterhal/archive/2005/07/05/435760.aspx

We get a lot of requests for addditions to the C# language and today I'm going to talk about one of the more common ones - switch on type. Switch on type looks like a pretty useful and straightforward feature: Add a switch-like construct which switches on the type of the expression, rather than the value. This might look something like this:

switch typeof(e) { 
        case int:    ... break; 
        case string: ... break; 
        case double: ... break; 
        default:     ... break; 
}

This kind of statement would be extremely useful for adding virtual method like dispatch over a disjoint type hierarchy, or over a type hierarchy containing types that you don't own. Seeing an example like this, you could easily conclude that the feature would be straightforward and useful. It might even get you thinking "Why don't those #*&%$ lazy C# language designers just make my life easier and add this simple, timesaving language feature?"

Unfortunately, like many 'simple' language features, type switch is not as simple as it first appears. The troubles start when you look at a more significant, and no less important, example like this:

class C {}
interface I {}
class D : C, I {}

switch typeof(e) {
case C: … break;
case I: … break;
default: … break;
}

In my case, I noticed this behavior when the box was out of memory (RAM) I went to Jenkins -> Manage Jenkins -> Manage Nodes and found an out of memory exception. I just freed up some memory on the machine and the jobs started to go into the executors.

I had a similar issue where I wanted a banner across the top of the screen that had one image on the left and a repeating image on the right to the edge of the screen. I ended up resolving it like so:

CSS:

.banner_left {
position: absolute;
top: 0px;
left: 0px;
width: 131px;
height: 150px;
background-image: url("left_image.jpg");
background-repeat: no-repeat;
}

.banner_right {
position: absolute;
top: 0px;
left: 131px;
right: 0px;
height: 150px;
background-image: url("right_repeating_image.jpg");
background-repeat: repeat-x;
background-position: top left;
}

The key was the right tag. I'm basically specifying that I want it to repeat from 131px in from the left to 0px from the right.

First make a xml file with contents shown below and name it border.xml and place it inside the layout folder inside the res directory

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="1dp" android:color="#0000" />
    <padding android:left="0dp" android:top="1dp" android:right="0dp"
        android:bottom="1dp" />
</shape>

After that inside the code use

TextView tv = (TextView)findElementById(R.id.yourTextView);
tv.setBackgroundResource(R.layout.border);

This will make a black line on top and bottom of the TextView.

Maybe off-topic, but R features two nice, fast and empty-aware functions for reducing logical vectors -- any and all:

if(any(x=='dolphin')) stop("Told you, no mammals!")

Use this to set the orientation of the screen:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

or

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

and don't forget to add this to your manifest:

android:configChanges = "orientation"

You can simply use Arrays.sort()

array.sort((a,b) => a.title.rendered.localeCompare(b.title.rendered));

Working Example :

var array = [{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"VPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""},},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"adfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"bbfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}}];_x000D_
array.sort((a,b) => a.title.rendered.localeCompare(b.title.rendered));_x000D_
 _x000D_
 console.log(array);

java.time

Here’s the modern answer.

    DateTimeFormatter sourceFormatter = DateTimeFormatter.ofPattern("dd/MM/uuuu");
    DateTimeFormatter displayFormatter = DateTimeFormatter
            .ofLocalizedDate(FormatStyle.SHORT)
            .withLocale(Locale.forLanguageTag("zh-SG"));

    String dateString = "31/05/2011";
    LocalDate date = LocalDate.parse(dateString, sourceFormatter);
    System.out.println(date.format(displayFormatter));

Output from this snippet is:

31/05/11

See if you can live with the 2-digit year. Or use FormatStyle.MEDIUM to obtain 2011?5?31?. I recommend you use Java’s built-in date and time formats when you can. It’s easier and lends itself very well to internationalization.

If you need the exact format you gave, just use the source formatter as display formatter too:

    System.out.println(date.format(sourceFormatter));

31/05/2011

I recommend you don’t use SimpleDateFormat. It’s notoriously troublesome and long outdated. Instead I use java.time, the modern Java date and time API.

To obtain a specific format you need to format the parsed date back into a string. Netiher an old-fashioned Date nor a modern LocalDatecan have a format in it.

Link: Oracle tutorial: Date Time explaining how to use java.time.

Obviously, Class.isAssignableFrom() tells you whether an individual class implements the given interface. So then the problem is getting the list of classes to test.

As far as I'm aware, there's no direct way from Java to ask the class loader for "the list of classes that you could potentially load". So you'll have to do this yourself by iterating through the visible jars, calling Class.forName() to load the class, then testing it.

However, it's a little easier if you just want to know classes implementing the given interface from those that have actually been loaded:

• via the Java Instrumentation framework, you can call Instrumentation.getAllLoadedClasses()
• via reflection, you can query the ClassLoader.classes field of a given ClassLoader.

If you use the instrumentation technique, then (as explained in the link) what happens is that your "agent" class is called essentially when the JVM starts up, and passed an Instrumentation object. At that point, you probably want to "save it for later" in a static field, and then have your main application code call it later on to get the list of loaded classes.

This one command which you can check almost everything:

java -cp tomcat/lib/catalina.jar org.apache.catalina.util.ServerInfo

or

tomcat/bin/catalina.sh version

And the output looks like this

Server version: Apache Tomcat/8.5.24
Server built:   Nov 27 2017 13:05:30 UTC
Server number:  8.5.24.0
OS Name:        Linux
OS Version:     4.4.0-137-generic
Architecture:   amd64
JVM Version:    1.8.0_131-b11
JVM Vendor:     Oracle Corporation

You don't specify the tables for Company and Date, and you might want to fix that.

Standard SQL using MERGE:

MERGE WorkRecord2 T
   USING Employee S
      ON T.EmployeeRun = S.EmployeeNo
         AND Company = '1'
         AND Date = '2013-05-06'
WHEN MATCHED THEN DELETE;

The answer from Devart is also standard SQL, though incomplete. It should look more like this:

DELETE
  FROM WorkRecord2
  WHERE EXISTS ( SELECT *
                   FROM Employee S
                  WHERE S.EmployeeNo = WorkRecord2.EmployeeRun
                        AND Company = '1'
                        AND Date = '2013-05-06' );

The important thing to note about the above is it is clear the delete is targeting a single table, as enforced in the second example by requiring a scalar subquery.

For me, the various proprietary syntax answers are harder to read and understand. I guess the mindset for is best described in the answer by frans eilering, i.e. the person writing the code doesn't necessarily care about the person who will read and maintain the code.

I believe that you want something like this:

a list of attributes from an object

The built-in function dir() can do this job.

Taken from help(dir) output on your Python shell:

dir(...)

dir([object]) -> list of strings

If called without an argument, return the names in the current scope.

Else, return an alphabetized list of names comprising (some of) the attributes of the given object, and of attributes reachable from it.

If the object supplies a method named __dir__, it will be used; otherwise the default dir() logic is used and returns:

• for a module object: the module's attributes.
• for a class object: its attributes, and recursively the attributes of its bases.
• for any other object: its attributes, its class's attributes, and recursively the attributes of its class's base classes.

For example:

$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> a = "I am a string"
>>>
>>> type(a)
<class 'str'>
>>>
>>> dir(a)
['__add__', '__class__', '__contains__', '__delattr__', '__doc__',
'__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__',
'__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__',
'__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__',
'__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__',
'__setattr__', '__sizeof__', '__str__', '__subclasshook__',
'_formatter_field_name_split', '_formatter_parser', 'capitalize',

'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'partition',
'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip',
'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title',
'translate', 'upper', 'zfill']

You cannot do this on multiple fields. You can also look for this.

I've compared performance (space and time) for a number of ways to store numpy arrays. Few of them support multiple arrays per file, but perhaps it's useful anyway.

Npy and binary files are both really fast and small for dense data. If the data is sparse or very structured, you might want to use npz with compression, which'll save a lot of space but cost some load time.

If portability is an issue, binary is better than npy. If human readability is important, then you'll have to sacrifice a lot of performance, but it can be achieved fairly well using csv (which is also very portable of course).

More details and the code are available at the github repo.

The short answer taken from the announcement of jQuery 3.0 Final Release :

Along with the regular version of jQuery that includes the ajax and effects modules, we’re releasing a “slim” version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code.

The file size (gzipped) is about 6k smaller, 23.6k vs 30k.

Usage:

sftp("file:/C:/home/file.txt", "ssh://user:pass@host/home");
sftp("ssh://user:pass@host/home/file.txt", "file:/C:/home");

Implementation

If you do not need the recording and playback functionality in your app, using off-the-shelf streaming app and player is a reasonable choice.

If you do need them to be in your app, however, you will have to look into MediaRecorder API (for the server/camera app) and MediaPlayer (for client/player app).

Quick sample code for the server:

// this is your network socket
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mCamera = getCameraInstance();
mMediaRecorder = new MediaRecorder();
mCamera.unlock();
mMediaRecorder.setCamera(mCamera);
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
// this is the unofficially supported MPEG2TS format, suitable for streaming (Android 3.0+)
mMediaRecorder.setOutputFormat(8);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mediaRecorder.setOutputFile(pfd.getFileDescriptor());
mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
mMediaRecorder.prepare();
mMediaRecorder.start();

On the player side it is a bit tricky, you could try this:

// this is your network socket, connected to the server
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(pfd.getFileDescriptor());
mMediaPlayer.prepare();
mMediaPlayer.start();

Unfortunately mediaplayer tends to not like this, so you have a couple of options: either (a) save data from socket to file and (after you have a bit of data) play with mediaplayer from file, or (b) make a tiny http proxy that runs locally and can accept mediaplayer's GET request, reply with HTTP headers, and then copy data from the remote server to it. For (a) you would create the mediaplayer with a file path or file url, for (b) give it a http url pointing to your proxy.

Emacs takes many launch options. The one that you are looking for is emacs -nw. This will open Emacs inside the terminal disregarding the DISPLAY environment variable even if it is set. The long form of this flag is emacs --no-window-system.

More information about Emacs launch options can be found in the manual.

I would use the get_cmap method. Ex.:

import matplotlib.pyplot as plt

plt.imshow(matrix, cmap=plt.get_cmap('gray'))

I'm building for Angular 4/5 and often working offline and so the following worked for me. First install the NPM:

npm install material-design-icons --save

Then add the following to styles.css:

@import '~material-design-icons/iconfont/material-icons.css';

You cannot iterate through a dictionary while its changing during for loop. Make a casting to list and iterate over that list, it works for me.

    for key in list(d):
        if not d[key]: 
            d.pop(key)

Here is just a reply from Richard Pickup on LinkedIn to a similar question of mine:

I've used cocos 2dx marmalade and unity on both iOS and android. For 2d games cocos2dx is the way to go every time. Unity is just too much overkill for 2d games and as already stated marmalade is just a thin abstraction layer not really a game engine. You can even run cocos2d on top of marmalade. My approach would be to use cocos2dx on iOS and android then in future run cocosd2dx code on top of marmalade as an easy way to port to bb10 and win phone 7

MySQL 5.7 or newer generates a default temporary password after fresh install.

To use MySQL first you would be required to get that password from the log file which is present at the /var/log/mysqld.log. So follow the following process:

1. grep 'temporary password' /var/log/mysqld.log

2. mysql_secure_installation

The second command is required to change the password for MySQL and also to make certain other changes like removing temporary databases, allow or disallow remote access to root user, delete anonymous users etc…

Just add attribute runAllManagedModulesForAllRequests="true" to system.webServer\modules in web.config.

This attribute is enabled by default in MVC and Dynamic Data projects.

These are the correct version that you can add in your build.gradle according to the API needs.

An example using SFINAE and template partial specialization, by writing a Has_foo concept check:

#include <type_traits>
struct A{};

struct B{ int foo(int a, int b);};

struct C{void foo(int a, int b);};

struct D{int foo();};

struct E: public B{};

// available in C++17 onwards as part of <type_traits>
template<typename...>
using void_t = void;

template<typename T, typename = void> struct Has_foo: std::false_type{};

template<typename T> 
struct Has_foo<T, void_t<
    std::enable_if_t<
        std::is_same<
            int, 
            decltype(std::declval<T>().foo((int)0, (int)0))
        >::value
    >
>>: std::true_type{};


static_assert(not Has_foo<A>::value, "A does not have a foo");
static_assert(Has_foo<B>::value, "B has a foo");
static_assert(not Has_foo<C>::value, "C has a foo with the wrong return. ");
static_assert(not Has_foo<D>::value, "D has a foo with the wrong arguments. ");
static_assert(Has_foo<E>::value, "E has a foo since it inherits from B");

Just use Hash.[] with the values in the array. For example:

arr = [1,2,3,4]
Hash[*arr] #=> gives {1 => 2, 3 => 4}

Thanks to @sehe for the one-line escape:

var escaped = new System.Xml.Linq.XText(unescaped).ToString();

In April 2017 a patch was merged into Safari, so it aligned with the other browsers. This was released with Safari 11.

O(n),I would say . I am doing for a balanced tree,applicable for all the trees. Assuming that you use recursion,

T(n) = 2*T(n/2) + 1 ----------> (1)

T(n/2) for left sub-tree and T(n/2) for right sub-tree and '1' for verifying the base case.

On Simplifying (1) you can prove that the traversal(either inorder or preorder or post order) is of order O(n).

SQL Server returns messages after a batch of statements has been executed. Normally, you'd use SQL GO to indicate the end of a batch and to retrieve the results:

PRINT '1'
GO

WAITFOR DELAY '00:00:05'

PRINT '2'
GO

WAITFOR DELAY '00:00:05'

PRINT '3'
GO

In this case, however, the print statement you want returned immediately is in the middle of a loop, so the print statements cannot be in their own batch. The only command I know of that will return in the middle of a batch is RAISERROR (...) WITH NOWAIT, which gbn has provided as an answer as I type this.

Ended up doing this using csvfix:

csvfix map -fv '' -tv '0' /tmp/people.csv > /tmp/people_fixed.csv

In case you know for sure which columns were meant to be integer or float, you can specify just them:

csvfix map -f 1 -fv '' -tv '0' /tmp/people.csv > /tmp/people_fixed.csv

Without specifying the exact columns, one may experience an obvious side-effect, where a blank string will be turned into a string with a 0 character.

It's really late now but I made a quick script which works for Windows, Mac and Linux, simply by using each command line:

import os, platform

def close():
    if platform.system() == "Windows":
        print("Press any key to exit . . .")
        os.system("pause>nul")
        exit()
    
    elif platform.system() == "Linux":
        os.system("read -n1 -r -p \"Press any key to exit . . .\" key")
        exit()
    
    elif platform.system() == "Darwin":
        print("Press any key to exit . . .")
        os.system("read -n 1 -s -p \"\"")
        exit()
    
    else:
        exit()

It uses only inbuilt functions, and should work for all three (although I've only tested Windows and Linux...).

Apache 2.4.3 (or maybe slightly earlier) added a new security feature that often results in this error. You would also see a log message of the form "client denied by server configuration". The feature is requiring an authorized user identity to access a directory. It is turned on by DEFAULT in the httpd.conf that ships with Apache. You can see the enabling of the feature with the directive

Require all denied

This basically says to deny access to all users. To fix this problem, either remove the denied directive (or much better) add the following directive to the directories you want to grant access to:

Require all granted

as in

<Directory "your directory here">
   Order allow,deny
   Allow from all
   # New directive needed in Apache 2.4.3: 
   Require all granted
</Directory>

When you click on the image you'll get the alert:

<img src="logo1.jpg" onClick='alert("Hello World!")'/>

if this is what you want.

To print the last column of a line just use $(NF):

awk '{print $(NF)}' 

The most important thing is, the action created must return partial view, see below.

public ActionResult _YourPartialViewSection()
{
    return PartialView();
}

I had the same problem, and what needed to be done was setup IIS Express properly.

I right clicked on my project Properties => Web (tab) and on Servers: Project URL was already pre-populated and I clicked the button "Create Virtual Directory".

I had just reinstalled (refreshed) windows and the IIS was not setup b/c it was new.

Hope this helps.

We have resolved the circular dependency(Parent-child Entities) by mapping the child entity instead of parent entity in Grails 4(GORM).

Example:

Class Person {
    String name
}

Class Employee extends Person{
    String empId
}

//Before my code 
Class Address {
    static belongsTo = [person: Person]
}

//We changed our Address class to:
Class Address {
    static belongsTo = [person: Employee]
}

Select * from table
where CONTAINS([Column], '"A00*"')  

will act as % same as

where [Column] Like 'A00%'

Here is a method that does not require editing the code and works regardless of the number of characters.

For Linux users, check the value of GIT_HOME in your .env file in the home directory.

1. Open terminal
2. Type cd home/<username>/
3. Open the .env file and check the value of GIT_HOME and select the git path appropriately

PS: If you are not able to find the .env file, click on View on the formatting tool bar, select Show hidden files. You should be able to find the .env file now.

Here is what i did for uploading photo using post request.

    HttpClient httpClient = new DefaultHttpClient();
    HttpPost postRequest = new HttpPost(upload_url);
    MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

    try {

        FileBody fb = new FileBody(new File(filePath), "image/jpeg");
        StringBody contentString = new StringBody(directoryID + "");

        entity.addPart("file", fb);
        entity.addPart("directory_id", contentString);
        postRequest.setEntity(entity);

        HttpResponse response = httpClient.execute(postRequest);
        // Read the response
        String jsonString = EntityUtils.toString(response.getEntity());
        Log.e("response after uploading file ", jsonString);

    } catch (Exception e) {
        Log.e("Error in uploadFile", e.getMessage());
    }
}

That is so basic that I am wondering what book you are using to study? Try

Further note: Terminology in discussing R can be crucial and sometimes tricky. Using the term "table" to refer to that structure leaves open the possibility that it was either a 'table'-classed, or a 'matrix'-classed, or a 'data.frame'-classed object. The answer above would succeed with any of them, while @BenBolker's suggestion below would only succeed with a 'data.frame'-classed object.

I am unrepentant in my phrasing despite the recent downvote. There is a ton of free introductory material for beginners in R: https://cran.r-project.org/other-docs.html

from PIL import Image
from resizeimage import resizeimage

def resize_file(in_file, out_file, size):
    with open(in_file) as fd:
        image = resizeimage.resize_thumbnail(Image.open(fd), size)
    image.save(out_file)
    image.close()

resize_file('foo.tif', 'foo_small.jpg', (256, 256))

I use this library:

pip install python-resize-image

How about this:

public T[] CloneCopy(T[] array, int startIndex, int endIndex) where T : ICloneable
{
    T[] retArray = new T[endIndex - startIndex];
    for (int i = startIndex; i < endIndex; i++)
    {
        array[i - startIndex] = array[i].Clone();
    }
    return retArray;

}

You then need to implement the ICloneable interface on all of the classes you need to use this on but that should do it.

Since Java 8 you can use the argument-less any method and the type argument will get inferred by the compiler:

verify(bar).doStuff(any());

Explanation

The new thing in Java 8 is that the target type of an expression will be used to infer type parameters of its sub-expressions. Before Java 8 only arguments to methods where used for type parameter inference (most of the time).

In this case the parameter type of doStuff will be the target type for any(), and the return value type of any() will get chosen to match that argument type.

This mechanism was added in Java 8 mainly to be able to compile lambda expressions, but it improves type inferences generally.

Primitive types

This doesn't work with primitive types, unfortunately:

public interface IBar {
    void doPrimitiveStuff(int i);

verify(bar).doPrimitiveStuff(any()); // Compiles but throws NullPointerException
verify(bar).doPrimitiveStuff(anyInt()); // This is what you have to do instead

The problem is that the compiler will infer Integer as the return value type of any(). Mockito will not be aware of this (due to type erasure) and return the default value for reference types, which is null. The runtime will try to unbox the return value by calling the intValue method on it before passing it to doStuff, and the exception gets thrown.

The issue Unexpected token '<' is because of missing the babel preset.

Solution : You have to configure your webpack configuration as follows

{
  test   : /\.jsx?$/,
  exclude: /(node_modules|bower_components)/,
  loader : 'babel',
  query  : {
    presets:[ 'react', 'es2015' ]
  }
}

here .jsx checks both .js and .jsx formats.

you can simply install the babel dependency using node as follows

npm install babel-preset-react

Thank you

why not using?

As the error states, it can't bind - which typically means it's in use by another process. From a command line run:

netstat -a -n -o

Interrogate the output for port 9999 in use in the left hand column.

If you just want the content as string, then the simple solution is to use the ReadFile function from the io/ioutil package. This function returns a slice of bytes which you can easily convert to a string.

package main

import (
    "fmt"
    "io/ioutil"
)

func main() {
    b, err := ioutil.ReadFile("file.txt") // just pass the file name
    if err != nil {
        fmt.Print(err)
    }

    fmt.Println(b) // print the content as 'bytes'

    str := string(b) // convert content to a 'string'

    fmt.Println(str) // print the content as a 'string'
}

You can achieve this by using simply as a returns set of records using return query.

CREATE OR REPLACE FUNCTION schemaName.get_two_users_from_school(schoolid bigint)
 RETURNS SETOF record
 LANGUAGE plpgsql
AS $function$
begin

 return query
  SELECT id, name FROM schemaName.user where school_id = schoolid;

end;
$function$

And call this function as : select * from schemaName.get_two_users_from_school(schoolid) as x(a bigint, b varchar);

With explode function of php

$array=explode(" ",$str); 

This is a quick example for you http://codepad.org/Pbg4n76i

If you're running Linux I would suggest two tools:

align_image_stack from package hugin-tools - is a commandline program that can automatically correct rotation, scaling, and other distortions (it's mostly intended for compositing HDR photography, but works for video frames and other documents too). More information: http://hugin.sourceforge.net/docs/manual/Align_image_stack.html

compare from package imagemagick - a program that can find and count the amount of different pixels in two images. Here's a neat tutorial: http://www.imagemagick.org/Usage/compare/ uising the -fuzz N% you can increase the error tolerance. The higher the N the higher the error tolerance to still count two pixels as the same.

align_image_stack should correct any offset so the compare command will actually have a chance of detecting same pixels.

Below are the methods to compare the dates but before that we need to identify the format of date stored in DB

I have dates stored in MM/DD/YYYY HH:MM format so it has to be compared in that format

1. Below query compares the convert the date into MM/DD/YYY format and get data from last five days till today. BETWEEN operator will help and you can simply specify start date AND end date.

   select * from myTable where myColumn BETWEEN strftime('%m/%d/%Y %H:%M', datetime('now','localtime'), '-5 day') AND strftime('%m/%d/%Y %H:%M',datetime('now','localtime')); 
   

2. Below query will use greater than operator (>).

     select * from myTable where myColumn > strftime('%m/%d/%Y %H:%M', datetime('now','localtime'), '-5 day');  

All the computation I have done is using current time, you can change the format and date as per your need.

Hope this will help you

Summved

Instead of:

int count = 0;
for (int i = 0; i<args.length -1; ++i)
    count++;
System.out.println(count);

 }

you can just

int count = args.length;

The average is the sum of your args divided by the number of your args.

int res = 0;
int count = args.lenght;

for (int a : args)
{
res += a;
}
res /= count;

you can make this code shorter too, i'll let you try and ask if you need help!

This is my first answerso tell me if something wrong!

You can find the second largest value with at most 2·(N-1) comparisons and two variables that hold the largest and second largest value:

largest := numbers[0];
secondLargest := null
for i=1 to numbers.length-1 do
    number := numbers[i];
    if number > largest then
        secondLargest := largest;
        largest := number;
    else
        if number > secondLargest then
            secondLargest := number;
        end;
    end;
end;

elem.classList.add("first");
elem.classList.add("second");
elem.classList.add("third");

is equal

elem.classList.add("first","second","third");

Try this

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {
    public static void main(String[] args) {
       SpringApplication.run(ScheduledTasks.class, args);
    }
}

You can extract the href from the a tag:

window.open(document.getElementById('redirect').href);
