Here is my swift solution as a UIView extension. It could be considered as a simulation of a UIActivityIndicator behaviour on any UIImageView.

import UIKit

extension UIView
{

    /**
    Starts rotating the view around Z axis.

    @param duration Duration of one full 360 degrees rotation. One second is default.
    @param repeatCount How many times the spin should be done. If not provided, the view will spin forever.
    @param clockwise Direction of the rotation. Default is clockwise (true).
     */
    func startZRotation(duration duration: CFTimeInterval = 1, repeatCount: Float = Float.infinity, clockwise: Bool = true)
    {
        if self.layer.animationForKey("transform.rotation.z") != nil {
            return
        }
        let animation = CABasicAnimation(keyPath: "transform.rotation.z")
        let direction = clockwise ? 1.0 : -1.0
        animation.toValue = NSNumber(double: M_PI * 2 * direction)
        animation.duration = duration
        animation.cumulative = true
        animation.repeatCount = repeatCount
        self.layer.addAnimation(animation, forKey:"transform.rotation.z")
    }


    /// Stop rotating the view around Z axis.
    func stopZRotation()
    {
        self.layer.removeAnimationForKey("transform.rotation.z")
    }

}

For Swift: Here is a simple extension to UIImage:

//ImageRotation.swift

import UIKit

extension UIImage {  
    public func imageRotatedByDegrees(degrees: CGFloat, flip: Bool) -> UIImage {
        let radiansToDegrees: (CGFloat) -> CGFloat = {
            return $0 * (180.0 / CGFloat(M_PI))
        }
        let degreesToRadians: (CGFloat) -> CGFloat = {
            return $0 / 180.0 * CGFloat(M_PI)
        }

        // calculate the size of the rotated view's containing box for our drawing space
        let rotatedViewBox = UIView(frame: CGRect(origin: CGPointZero, size: size))
        let t = CGAffineTransformMakeRotation(degreesToRadians(degrees));
        rotatedViewBox.transform = t
        let rotatedSize = rotatedViewBox.frame.size

        // Create the bitmap context
        UIGraphicsBeginImageContext(rotatedSize)
        let bitmap = UIGraphicsGetCurrentContext()

        // Move the origin to the middle of the image so we will rotate and scale around the center.
        CGContextTranslateCTM(bitmap, rotatedSize.width / 2.0, rotatedSize.height / 2.0);

        //   // Rotate the image context
        CGContextRotateCTM(bitmap, degreesToRadians(degrees));

        // Now, draw the rotated/scaled image into the context
        var yFlip: CGFloat

        if(flip){
            yFlip = CGFloat(-1.0)
        } else {
            yFlip = CGFloat(1.0)
        }

        CGContextScaleCTM(bitmap, yFlip, -1.0)
        CGContextDrawImage(bitmap, CGRectMake(-size.width / 2, -size.height / 2, size.width, size.height), CGImage)

        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return newImage
    }
}

Use it with:

rotatedPhoto = rotatedPhoto?.imageRotatedByDegrees(90, flip: false) 

The former will rotate an image and flip it if flip is set to true.

Here's a way with gsub:

cs <- c("foo_bar","bar_foo","apple","beer")
gsub('.{3}$', '', cs)
# [1] "foo_" "bar_" "ap"   "b"

Just to expand on @splattne's answer a little:

MapPath(string virtualPath) calls the following:

public string MapPath(string virtualPath)
{
    return this.MapPath(VirtualPath.CreateAllowNull(virtualPath));
}

MapPath(VirtualPath virtualPath) in turn calls MapPath(VirtualPath virtualPath, VirtualPath baseVirtualDir, bool allowCrossAppMapping) which contains the following:

//...
if (virtualPath == null)
{
    virtualPath = VirtualPath.Create(".");
}
//...

So if you call MapPath(null) or MapPath(""), you are effectively calling MapPath(".")

In Java 8, an interface looks like an abstract class although their might be some differences such as :

1) Abstract classes are classes, so they are not restricted to other restrictions of the interface in Java e.g. abstract class can have the state, but you cannot have the state on the interface in Java.

2) Another semantic difference between interface with default methods and abstract class is that you can define constructors inside an abstract class, but you cannot define constructor inside interface in Java

An improved version for recursive approach suggested by @schirrmacher to print key[value] for the entire object:

var jDepthLvl = 0;
function visit(object, objectAccessor=null) {
  jDepthLvl++;
  if (isIterable(object)) {
    if(objectAccessor === null) {
      console.log("%c ? ? printing object $OBJECT_OR_ARRAY$ -- START ? ?", "background:yellow");
    } else
      console.log("%c"+spacesDepth(jDepthLvl)+objectAccessor+"%c:","color:purple;font-weight:bold", "color:black");
    forEachIn(object, function (accessor, child) {
      visit(child, accessor);
    });
  } else {
    var value = object;
    console.log("%c"
      + spacesDepth(jDepthLvl)
      + objectAccessor + "[%c" + value + "%c] "
      ,"color:blue","color:red","color:blue");
  }
  if(objectAccessor === null) {
    console.log("%c ? ? printing object $OBJECT_OR_ARRAY$ -- END ? ?", "background:yellow");
  }
  jDepthLvl--;
}

function spacesDepth(jDepthLvl) {
  let jSpc="";
  for (let jIter=0; jIter<jDepthLvl-1; jIter++) {
    jSpc+="\u0020\u0020"
  }
  return jSpc;
}

function forEachIn(iterable, functionRef) {
  for (var accessor in iterable) {
    functionRef(accessor, iterable[accessor]);
  }
}

function isIterable(element) {
  return isArray(element) || isObject(element);
}

function isArray(element) {
  return element.constructor == Array;
}

function isObject(element) {
  return element.constructor == Object;
}


visit($OBJECT_OR_ARRAY$);

While Ryan is correct, the solution can be much simpler based on what is known about the source of the randomness. To re-state the problem:

• There is a source of randomness, outputting integer numbers in range [0, MAX) with uniform distribution.
• The goal is to produce uniformly distributed random integer numbers in range [rmin, rmax] where 0 <= rmin < rmax < MAX.

In my experience, if the number of bins (or "boxes") is significantly smaller than the range of the original numbers, and the original source is cryptographically strong - there is no need to go through all that rigamarole, and simple modulo division would suffice (like output = rnd.next() % (rmax+1), if rmin == 0), and produce random numbers that are distributed uniformly "enough", and without any loss of speed. The key factor is the randomness source (i.e., kids, don't try this at home with rand()).

Here's an example/proof of how it works in practice. I wanted to generate random numbers from 1 to 22, having a cryptographically strong source that produced random bytes (based on Intel RDRAND). The results are:

Rnd distribution test (22 boxes, numbers of entries in each box):     
 1: 409443    4.55%
 2: 408736    4.54%
 3: 408557    4.54%
 4: 409125    4.55%
 5: 408812    4.54%
 6: 409418    4.55%
 7: 408365    4.54%
 8: 407992    4.53%
 9: 409262    4.55%
10: 408112    4.53%
11: 409995    4.56%
12: 409810    4.55%
13: 409638    4.55%
14: 408905    4.54%
15: 408484    4.54%
16: 408211    4.54%
17: 409773    4.55%
18: 409597    4.55%
19: 409727    4.55%
20: 409062    4.55%
21: 409634    4.55%
22: 409342    4.55%   
total: 100.00%

This is as close to uniform as I need for my purpose (fair dice throw, generating cryptographically strong codebooks for WWII cipher machines such as http://users.telenet.be/d.rijmenants/en/kl-7sim.htm, etc). The output does not show any appreciable bias.

Here's the source of cryptographically strong (true) random number generator: Intel Digital Random Number Generator and a sample code that produces 64-bit (unsigned) random numbers.

int rdrand64_step(unsigned long long int *therand)
{
  unsigned long long int foo;
  int cf_error_status;

  asm("rdrand %%rax; \
        mov $1,%%edx; \
        cmovae %%rax,%%rdx; \
        mov %%edx,%1; \
        mov %%rax, %0;":"=r"(foo),"=r"(cf_error_status)::"%rax","%rdx");
        *therand = foo;
  return cf_error_status;
}

I compiled it on Mac OS X with clang-6.0.1 (straight), and with gcc-4.8.3 using "-Wa,q" flag (because GAS does not support these new instructions).

I think since we don't have $rootScope kind of thing in angular 2 as in angular 1.x. We can use angular 2 shared service/class while in ngOnDestroy pass data to service and after routing take the data from the service in ngOnInit function:

Here I am using DataService to share hero object:

import { Hero } from './hero';
export class DataService {
  public hero: Hero;
}

Pass object from first page component:

 ngOnDestroy() {
    this.dataService.hero = this.hero; 
 }

Take object from second page component:

 ngOnInit() {
    this.hero = this.dataService.hero; 
 }

Here is an example: plunker

Edit: Note that this answer is now out of date. See Siarhei Kuchuk's answer below for a better fix

UrlEncoding will do what you are suggesting here. With C#, you simply use HttpUtility, as mentioned.

You can also Regex the illegal characters and then replace, but this gets far more complex, as you will have to have some form of state machine (switch ... case, for example) to replace with the correct characters. Since UrlEncode does this up front, it is rather easy.

As for Linux versus windows, there are some characters that are acceptable in Linux that are not in Windows, but I would not worry about that, as the folder name can be returned by decoding the Url string, using UrlDecode, so you can round trip the changes.

Well, I had a similar challenge. Using the inspect element tool in Firefox, I was able to trace the markup and the CSS used to style the link when clicked. On click, the list item (li) is given a class of .open and it's the anchor tag in the class that is formatted with the grey color background.

To fix this, just add this to your stylesheet.

.nav .open > a
{
    background:#759ad6;
    // Put in styling
}

/WebKit/.test(navigator.userAgent) — that's it.

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob; 


 "I have finished inputting your clob: 60030"

Use a Library Project just for the Support Library

As of ADT 22, using Eclipse Juno

I don't think any of the above are really the best answers. I also don't think it is recommended to use the external jar function in Eclipse anymore (AFAIK).

Rather, what worked for me is to create a separate empty library project.

Then use Android tools > Add Support Library to get the latest version you need or want.

Then remove the support lib jar from all other projects.

Finally, for every project that requires it, add a reference to your new Library project

(project properties) > Android > (Library box) > Add...

Then all your projects will have a single source to use and update the support library. This also makes javadocs easier to get working.

For info on how to setup the javadocs see:

How to attach javadoc or sources to jars in libs folder?

In case you do not want to use Asset Catalog, you can add an iOS 7 icon for an old app by creating a 120x120 .png image. Name it Icon-120.png and drag in to the project.

Under TARGET > Your App > Info > Icon files, add one more entry in the Target Properties:

I tested on Xcode 5 and an app was submitted without the missing retina icon warning.

The sieve of Atkin is an optimized version of the sieve of Eratosthenes which gives all prime numbers up to a given integer. You should be able to google this for more detail.

Once you have that list, it's a simple matter to divide your number by each prime to see if it's an exact divisor (i.e., remainder is zero).

The basic steps calculating the divisors for a number (n) are [this is pseudocode converted from real code so I hope I haven't introduced errors]:

for z in 1..n:
    prime[z] = false
prime[2] = true;
prime[3] = true;

for x in 1..sqrt(n):
    xx = x * x

    for y in 1..sqrt(n):
        yy = y * y

        z = 4*xx+yy
        if (z <= n) and ((z mod 12 == 1) or (z mod 12 == 5)):
            prime[z] = not prime[z]

        z = z-xx
        if (z <= n) and (z mod 12 == 7):
            prime[z] = not prime[z]

        z = z-yy-yy
        if (z <= n) and (x > y) and (z mod 12 == 11):
            prime[z] = not prime[z]

for z in 5..sqrt(n):
    if prime[z]:
        zz = z*z
        x = zz
        while x <= limit:
            prime[x] = false
            x = x + zz

for z in 2,3,5..n:
    if prime[z]:
        if n modulo z == 0 then print z

I've seen many answers but they seem confusing to me. Can't we just simply use Type Casting.

For ex:-

int s;
char i= '2';
s = (int) i;

In your link.php your echo statement must be like this:

echo '<a href="pass.php?link=' . $a . '>Link 1</a>';
echo '<a href="pass.php?link=' . $b . '">Link 2</a>';

Then in your pass.php you cannot use $a because it was not initialized with your intended string value.

You can directly compare it to a string like this:

if($_GET['link'] == 'Link1')

Another way is to initialize the variable first to the same thing you did with link.php. And, a much better way is to include the $a and $b variables in a single PHP file, then include that in all pages where you are going to use those variables as Tim Cooper mention on his post. You can also include this in a session.

Try this:

<SCRIPT LANGUAGE="JavaScript">
 function WriteToFile(passForm) {

    set fso = CreateObject("Scripting.FileSystemObject");  
    set s = fso.CreateTextFile("C:\test.txt", True);
    s.writeline("HI");
    s.writeline("Bye");
    s.writeline("-----------------------------");
    s.Close();
 }
  </SCRIPT>

</head>

<body>
<p>To sign up for the Excel workshop please fill out the form below:
</p>
<form onSubmit="WriteToFile(this)">
Type your first name:
<input type="text" name="FirstName" size="20">
<br>Type your last name:
<input type="text" name="LastName" size="20">
<br>
<input type="submit" value="submit">
</form> 

This will work only on IE

If you are trying to create a File from some ready path (saved in database, per example) using Linux separator, what should I do?

Maybe just use the path do create the file:

new File("/shared/folder/file.jpg");

But Windows use a different separator (\). So, is the alternative convert the slash separator to platform independent? Like:

new File(convertPathToPlatformIndependent("/shared/folder"));

This method convertPathToPlatformIndependent probably will have some kind of split by "/" and join with File.separator.

Well, for me, that's not nice for a language that is platform independent (right?) and Java already support the use of / on Windows or Linux. But if you are working with paths and need to remember to this conversion every single time this will be a nightmare and you won't have any real gain for the application on the future (maybe in the universe that @Pointy described).

It's compiling because printf isn't type safe, since it uses variable arguments in the C sense¹. printf has no option for std::string, only a C-style string. Using something else in place of what it expects definitely won't give you the results you want. It's actually undefined behaviour, so anything at all could happen.

The easiest way to fix this, since you're using C++, is printing it normally with std::cout, since std::string supports that through operator overloading:

std::cout << "Follow this command: " << myString;

If, for some reason, you need to extract the C-style string, you can use the c_str() method of std::string to get a const char * that is null-terminated. Using your example:

#include <iostream>
#include <string>
#include <stdio.h>

int main()
{
    using namespace std;

    string myString = "Press ENTER to quit program!";
    cout << "Come up and C++ me some time." << endl;
    printf("Follow this command: %s", myString.c_str()); //note the use of c_str
    cin.get();

    return 0;
}

If you want a function that is like printf, but type safe, look into variadic templates (C++11, supported on all major compilers as of MSVC12). You can find an example of one here. There's nothing I know of implemented like that in the standard library, but there might be in Boost, specifically boost::format.

[1]: This means that you can pass any number of arguments, but the function relies on you to tell it the number and types of those arguments. In the case of printf, that means a string with encoded type information like %d meaning int. If you lie about the type or number, the function has no standard way of knowing, although some compilers have the ability to check and give warnings when you lie.

If the button tag is inside the div element who contains the modal, you can do something like:

<button class="btn btn-default" data-dismiss="modal" aria-label="Close">Cancel</button>

df.shape, where df is your DataFrame.

There actually IS a way to do it in Python 2.3+, but it's a bit esoteric. I don't know if you realize this, but you can do the following:

$ unzip -l /tmp/example.zip
 Archive:  /tmp/example.zip
   Length     Date   Time    Name
 --------    ----   ----    ----
     8467  11-26-02 22:30   jwzthreading.py
 --------                   -------
     8467                   1 file
$ ./python
Python 2.3 (#1, Aug 1 2003, 19:54:32) 
>>> import sys
>>> sys.path.insert(0, '/tmp/example.zip')  # Add .zip file to front of path
>>> import jwzthreading
>>> jwzthreading.__file__
'/tmp/example.zip/jwzthreading.py'

According to the zipimport library:

Any files may be present in the ZIP archive, but only files .py and .py[co] are available for import. ZIP import of dynamic modules (.pyd, .so) is disallowed. Note that if an archive only contains .py files, Python will not attempt to modify the archive by adding the corresponding .pyc or .pyo file, meaning that if a ZIP archive doesn't contain .pyc files, importing may be rather slow.

Thus, all you have to do is zip the files up, add the zipfile to your sys.path and then import them.

If you're building this for UNIX, you might also consider packaging your script using this recipe: unix zip executable, but note that you might have to tweak this if you plan on using stdin or reading anything from sys.args (it CAN be done without too much trouble).

In my experience performance doesn't suffer too much because of this, but you should think twice before importing any very large modules this way.

It can be solved in case of use of a proxy that intercept the request and write the appropriate headers. In the particular case of Varnish these would be the rules:

if (req.http.host == "CUSTOM_URL" ) {
set resp.http.Access-Control-Allow-Origin = "*";
if (req.method == "OPTIONS") {
   set resp.http.Access-Control-Max-Age = "1728000";
   set resp.http.Access-Control-Allow-Methods = "GET, POST, PUT, DELETE, PATCH, OPTIONS";
   set resp.http.Access-Control-Allow-Headers = "Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since";
   set resp.http.Content-Length = "0";
   set resp.http.Content-Type = "text/plain charset=UTF-8";
   set resp.status = 204;
}

}

However many years late this response may be, anyone coming across this might just want to try

li {
    display: flex;
    flex-direction: row;
    align-items: center;
}

Browser support for flexbox is far better than it was when @scottjoudry posted his response above, but you may still want to consider prefixing or other options if you're trying to support much older browsers. caniuse: flex

Perhaps Multi-Column Layouts Climb Out of the Box is what you're looking for?

Old black and white version (there's nothing new under the sun) http://www.lore.ua.ac.be/Teaching/SE3BAC/SoftwareSpecCartoon.gif

Generally means that its a file that needs to be included and does not make standalone script in itself.

This is a convention not a programming technique.

Although if your web server is not configured properly it could expose files with extensions like .inc.

If your computer has python, you can try this from the shell:

python -c "print len(open('test.txt').read().split('\n'))"

This uses python -c to pass in a command, which is basically reading the file, and splitting by the "newline", to get the count of newlines, or the overall length of the file.

@BlueMoon's:

bash-3.2$ sed -n '$=' test.txt
519

Using the above:

bash-3.2$ python -c "print len(open('test.txt').read().split('\n'))"
519

Console.Read()

=> reads only one character from the standard input

Console.ReadLine()

=> reads all characters in the line from the standard input

TL;DR: List.stream().forEach() was the fastest.

I felt I should add my results from benchmarking iteration. I took a very simple approach (no benchmarking frameworks) and benchmarked 5 different methods:

1. classic for
2. classic foreach
3. List.forEach()
4. List.stream().forEach()
5. List.parallelStream().forEach

the testing procedure and parameters

private List<Integer> list;
private final int size = 1_000_000;

public MyClass(){
    list = new ArrayList<>();
    Random rand = new Random();
    for (int i = 0; i < size; ++i) {
        list.add(rand.nextInt(size * 50));
    }    
}
private void doIt(Integer i) {
    i *= 2; //so it won't get JITed out
}

The list in this class shall be iterated over and have some doIt(Integer i) applied to all it's members, each time via a different method. in the Main class I run the tested method three times to warm up the JVM. I then run the test method 1000 times summing the time it takes for each iteration method (using System.nanoTime()). After that's done i divide that sum by 1000 and that's the result, average time. example:

myClass.fored();
myClass.fored();
myClass.fored();
for (int i = 0; i < reps; ++i) {
    begin = System.nanoTime();
    myClass.fored();
    end = System.nanoTime();
    nanoSum += end - begin;
}
System.out.println(nanoSum / reps);

I ran this on a i5 4 core CPU, with java version 1.8.0_05

classic for

for(int i = 0, l = list.size(); i < l; ++i) {
    doIt(list.get(i));
}

execution time: 4.21 ms

classic foreach

for(Integer i : list) {
    doIt(i);
}

execution time: 5.95 ms

List.forEach()

list.forEach((i) -> doIt(i));

execution time: 3.11 ms

List.stream().forEach()

list.stream().forEach((i) -> doIt(i));

execution time: 2.79 ms

List.parallelStream().forEach

list.parallelStream().forEach((i) -> doIt(i));

execution time: 3.6 ms

I'm written an extension to make this easier:

extension UIViewController {

    /// Convenience for setting the back button, which will be used on any view controller that this one pushes onto the stack
    @objc var backButtonTitle: String? {
        get {
            return navigationItem.backBarButtonItem?.title
        }
        set {
            if let existingBackBarButtonItem = navigationItem.backBarButtonItem {
                existingBackBarButtonItem.title = newValue
            }
            else {
                let newNavigationItem = UIBarButtonItem(title: newValue, style:.plain, target: nil, action: nil)
                navigationItem.backBarButtonItem = newNavigationItem
            }
        }
    }

}

fileExists() is a method of FileSystemObject, not a global scope function.

You also have an issue with the delete, DeleteFile() is also a method of FileSystemObject.

Furthermore, it seems you are moving the file and then attempting to deal with the overwrite issue, which is out of order. First you must detect the name collision, so you can choose the rename the file or delete the collision first. I am assuming for some reason you want to keep deleting the new files until you get to the last one, which seemed implied in your question.

So you could use the block:

if NOT fso.FileExists(newname) Then  

    file.move fso.buildpath(OUT_PATH, newname)           

else

    fso.DeleteFile newname
    file.move fso.buildpath(OUT_PATH, newname)  

end if 

Also be careful that your string comparison with the = sign is case sensitive. Use strCmp with vbText compare option for case insensitive string comparison.

@hai-phan's answer using LEFT JOIN is the key, but it might be a bit hard to follow. I had a complicated query that may also return nothing. I just simplified his answer to my need. It's easy to apply to query with many columns.

;WITH CTE AS (
  -- SELECT S.Id, ...
  -- FROM Sites S WHERE Id = @SiteId
  -- EXCEPT SOME CONDITION.
  -- Whatever your query is
)
SELECT CTE.* -- If you want something else instead of NULL, use COALESCE.
FROM (SELECT @SiteId AS ID) R
LEFT JOIN CTE ON CTE.Id = R.ID

Update: This answer on SqlServerCentral is the best. It utilizes this feature of MAX - "MAX returns NULL when there is no row to select."

SELECT ISNULL(MAX(value), 0) FROM table WHERE Id = @SiteId

Have just solved. Just two f. days of brutforce

For me the secret was in following:

1. I called POST /api/auth and see that cookies were successfully received.

2. Then calling GET /api/users/ with credentials: 'include' and got 401 unauth, because of no cookies were sent with the request.

The KEY is to set credentials: 'include' for the first /api/auth call too.

In my experience window.requestAnimationFrame wasn't enough to ensure that the DOM had been fully rendered / reflow-complete from componentDidMount. I have code running that accesses the DOM immediately after a componentDidMount call and using solely window.requestAnimationFrame would result in the element being present in the DOM; however, updates to the element's dimensions aren't reflected yet since a reflow hasn't yet occurred.

The only truly reliable way for this to work was to wrap my method in a setTimeout and a window.requestAnimationFrame to ensure React's current call stack gets cleared before registering for the next frame's render.

function onNextFrame(callback) {
    setTimeout(function () {
        requestAnimationFrame(callback)
    })
}

If I had to speculate on why this is occurring / necessary I could see React batching DOM updates and not actually applying the changes to the DOM until after the current stack is complete.

Ultimately, if you're using DOM measurements in the code you're firing after the React callbacks you'll probably want to use this method.

I did all the tricks here on My Fork to fix page 404 on Github Page but it kept 404'ing.

Finaly found that my browser hardly keep the 10 minutes cache before it up on the web.

Just add /index.html into the end of URL then it showed up and solved the case.

https://username.github.io/index.html

I have done it like:

            using (StreamReader sr = File.OpenText(jsonFilePath))
            {
                var myObject = JsonConvert.DeserializeObject<List<YourObject>>(sr.ReadToEnd());
            }

also, you can do this with async call like: sr.ReadToEndAsync(). using Newtonsoft.Json as reference.

Hope, this helps.

read.table wants to return a data.frame, which must have an element in each column. Therefore R expects each row to have the same number of elements and it doesn't fill in empty spaces by default. Try read.table("/PathTo/file.csv" , fill = TRUE ) to fill in the blanks.

e.g.

read.table( text= "Element1 Element2
Element5 Element6 Element7" , fill = TRUE , header = FALSE )
#        V1       V2       V3
#1 Element1 Element2         
#2 Element5 Element6 Element7

A note on whether or not to set header = FALSE... read.table tries to automatically determine if you have a header row thus:

header is set to TRUE if and only if the first row contains one fewer field than the number of columns

Override using JavaScript

$('.mytable td').attr('style', 'display: none !important');

Worked for me.

Updated for Swift 3

import UIKit

class ViewController: UIViewController {

let redView: UIView = {

    let view = UIView()
    view.translatesAutoresizingMaskIntoConstraints = false
    view.backgroundColor = .red
    return view
}()

override func viewDidLoad() {
    super.viewDidLoad()

    setupViews()
    setupAutoLayout()
}

func setupViews() {

    view.backgroundColor = .white
    view.addSubview(redView)
}

func setupAutoLayout() {

    // Available from iOS 9 commonly known as Anchoring System for AutoLayout...
    redView.leftAnchor.constraint(equalTo: view.leftAnchor, constant: 20).isActive = true
    redView.rightAnchor.constraint(equalTo: view.rightAnchor, constant: -20).isActive = true

    redView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
    redView.heightAnchor.constraint(equalToConstant: 300).isActive = true

    // You can also modified above last two lines as follows by commenting above & uncommenting below lines...
    // redView.topAnchor.constraint(equalTo: view.topAnchor, constant: 20).isActive = true
    // redView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
 }
}

Type of Constraints

 /*
// regular use
1.leftAnchor
2.rightAnchor
3.topAnchor
// intermediate use
4.widthAnchor
5.heightAnchor
6.bottomAnchor
7.centerXAnchor
8.centerYAnchor
// rare use
9.leadingAnchor
10.trailingAnchor
etc. (note: very project to project)
*/

Try Request.Url.Query if you want the raw querystring as a string.

if let/if var optional binding only works when the result of the right side of the expression is an optional. If the result of the right side is not an optional, you can not use this optional binding. The point of this optional binding is to check for nil and only use the variable if it's non-nil.

In your case, the tableView parameter is declared as the non-optional type UITableView. It is guaranteed to never be nil. So optional binding here is unnecessary.

func tableView(tableView: UITableView, commitEditingStyle editingStyle:UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if editingStyle == .Delete {
        // Delete the row from the data source
        myData.removeAtIndex(indexPath.row)
        tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)

All we have to do is get rid of the if let and change any occurrences of tv within it to just tableView.

You might don't need any web site for that, only open up the browser, press F12 to get access to developer tools > console, then in console write some JavaScript Code to do that.

Here I share some ways to accomplish that:

For GET request: *.Using jQuery:

$.get("http://someurl/status/?messageid=597574445", function(data, status){
    console.log(data, status);
  });

For POST request: 1. Using jQuery $.ajax:

var url= "http://someurl/",
        api_key = "6136-bc16-49fb-bacb-802358",
        token1 = "Just for test",
        result;
    $.ajax({
          url: url,
          type: "POST",
          data: {
            api_key: api_key,
            token1: token1
          },
        }).done(function(result) {
                console.log("done successfuly", result);
        }).fail(function(error) {

          console.log(error.responseText, error);

        });

2. Using jQuery, append and submit

    var merchantId = "AA86E",
           token = "4107120133142729",
           url = "https://payment.com/Index";
   
       var form = `<form id="send-by-post" method="post" action="${url}">
                                   <input id="token" type="hidden" name="token" value="${merchantId}"/>
                                   <input id="merchantId" name="merchantId" type="hidden" value="${token}"/>
                                   <button type="submit" >Pay</button>
                       </div>
                   </form> `; 
       $('body').append(form);
       $("#send-by-post").submit();//Or $(form).appendTo("body").submit();
   

   3. Using Pure JavaScript:

   var api_key = "73736-bc16-49fb-bacb-643e58", recipient = "095552565", token1 = "4458", url = 'http://smspanel.com/send/';

var form = `<form id="send-by-post" method="post" action="${url}"> <input id="api_key" type="hidden" name="api_key" value="${api_key}"/> <input id="recipient" type="hidden" name="recipient" value="${recipient}"/> <input id="token1" name="token1" type="hidden" value="${token1}"/> <button type="submit" >Send</button> </div> </form>`;

document.querySelector("body").insertAdjacentHTML('beforeend',form);
document.querySelector("#send-by-post").submit();

4. Or even using ASP.Net:

   var url = "https://Payment.com/index"; Response.Clear(); var sb = new System.Text.StringBuilder();

   sb.Append(""); sb.AppendFormat(""); sb.AppendFormat("", url); sb.AppendFormat("", "C668"); sb.AppendFormat("", "22720281459"); sb.Append(""); sb.Append(""); sb.Append(""); Response.Write(sb.ToString()); Response.End();

(Note: Since I have backtick character (`) in my code the code format ruined, I have no idea how to correct it)

Nested if's in Excel Are ugly:

=If(G2 < 1, .1, IF(G2 < 5,.15,if(G2 < 15,.2,if(G2 < 30,.5,if(G2 < 100,.1,1.3)))))

That should cover it.

You forgot to specify the variable name. It should be CERas.CERAS newCeras = new CERas.CERAS();

To convert UTC time to Local you have to use moment.local().

For more info see docs

Example:

var date = moment.utc().format('YYYY-MM-DD HH:mm:ss');

console.log(date); // 2015-09-13 03:39:27

var stillUtc = moment.utc(date).toDate();
var local = moment(stillUtc).local().format('YYYY-MM-DD HH:mm:ss');

console.log(local); // 2015-09-13 09:39:27

Demo:

var date = moment.utc().format();_x000D_
console.log(date, "- now in UTC"); _x000D_
_x000D_
var local = moment.utc(date).local().format();_x000D_
console.log(local, "- UTC now to local");

It's a new year and there's a new mismatch between the version of protobuf in Homebrew and the cutting edge release. As of February 2016, brew install protobuf will give you version 2.6.1.

If you want the 3.0 beta release instead, you can install it with:

brew install --devel protobuf

Look if you have another service or program running on the http port. It happened to me when I tried to use the port and it was taken by another program.

Here is part of a line in my code that brought the warning up in NetBeans:

$page = (!empty($_GET['p'])) 

After much research and seeing how there are about a bazillion ways to filter this array, I found one that was simple. And my code works and NetBeans is happy:

$p = filter_input(INPUT_GET, 'p');
$page = (!empty($p))

Try dropping the .value

DateTimeExtended(DateTimeExtended myNewDT)
{
   this.MyDateTime = myNewDT.MyDateTime;
   this.otherdata = myNewDT.otherdata;
}

as a function

var arrayChunk = function (array, chunkSize) {
            var arrayOfArrays = [];

            if (array.length <= chunkSize) {
                arrayOfArrays.push(array);
            } else {
                for (var i=0; i<array.length; i+=chunkSize) {
                    arrayOfArrays.push(array.slice(i,i+chunkSize));
                }
            }
            return arrayOfArrays;
        }

to use

arrayChunk(originalArray, 10) //10 being the chunk size.

map is the most logical solution for this problem.

let xs = [1, 2, 3];
xs = xs.map(x => 42);
xs // -> [42, 42, 42]

However, if there is a chance that the array is sparse, you'll need to use for or, even better, for .. of.

See:

• https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/map
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of

Here is what I do to avoid the issues of making the remote server accept your local external IP:

• when I ssh into the machine, I use the option -L to transfer the port 6006 of the remote server into the port 16006 of my machine (for instance): ssh -L 16006:127.0.0.1:6006 olivier@my_server_ip

What it does is that everything on the port 6006 of the server (in 127.0.0.1:6006) will be forwarded to my machine on the port 16006.

• You can then launch tensorboard on the remote machine using a standard tensorboard --logdir log with the default 6006port
• On your local machine, go to http://127.0.0.1:16006 and enjoy your remote TensorBoard.

I couldn't find the code in the doc suggested by the accepted answer but I found the updated equivalent here:

File System Programming Guide :: Accessing Files and Directories »

- (NSURL*)applicationDataDirectory {
    NSFileManager* sharedFM = [NSFileManager defaultManager];
    NSArray* possibleURLs = [sharedFM URLsForDirectory:NSApplicationSupportDirectory
                                 inDomains:NSUserDomainMask];
    NSURL* appSupportDir = nil;
    NSURL* appDirectory = nil;

    if ([possibleURLs count] >= 1) {
        // Use the first directory (if multiple are returned)
        appSupportDir = [possibleURLs objectAtIndex:0];
    }

    // If a valid app support directory exists, add the
    // app's bundle ID to it to specify the final directory.
    if (appSupportDir) {
        NSString* appBundleID = [[NSBundle mainBundle] bundleIdentifier];
        appDirectory = [appSupportDir URLByAppendingPathComponent:appBundleID];
    }

    return appDirectory;
}

It discourages use of NSSearchPathForDirectoriesInDomain:

The NSSearchPathForDirectoriesInDomains function behaves like the URLsForDirectory:inDomains: method but returns the directory’s location as a string-based path. You should use the URLsForDirectory:inDomains: method instead.

Here are some other useful directory constants to play with. No doubt not all of these are supported in iOS. Also you can use the NSHomeDirectory() function which:

In iOS, the home directory is the application’s sandbox directory. In OS X, it is the application’s sandbox directory or the current user’s home directory (if the application is not in a sandbox)

From NSPathUtilities.h

NSApplicationDirectory = 1,             // supported applications (Applications)

Based on the number of views this question has, it looks like a lot of people are visiting this to see how to set up a job that executes a shell script.

These are the steps to execute a shell script in Jenkins:

• In the main page of Jenkins select New Item.
• Enter an item name like "my shell script job" and chose Freestyle project. Press OK.
• On the configuration page, in the Build block click in the Add build step dropdown and select Execute shell.

• In the textarea you can either paste a script or indicate how to run an existing script. So you can either say:

  #!/bin/bash
  
  echo "hello, today is $(date)" > /tmp/jenkins_test
  

  or just

  /path/to/your/script.sh
  

• Click Save.

Now the newly created job should appear in the main page of Jenkins, together with the other ones. Open it and select Build now to see if it works. Once it has finished pick that specific build from the build history and read the Console output to see if everything happened as desired.

You can get more details in the document Create a Jenkins shell script job in GitHub.

It is possible to use raw query within a Spring Repository.

      @Query(value = "SELECT A.IS_MUTUAL_AID FROM planex AS A 
             INNER JOIN planex_rel AS B ON A.PLANEX_ID=B.PLANEX_ID  
             WHERE B.GOOD_ID = :goodId",nativeQuery = true)

      Boolean mutualAidFlag(@Param("goodId")Integer goodId);

slightly off-topic (using the CLI instead of PHP), but still worth knowing: You can set the prompt to display the default database by using any of the following

mysql --prompt='\d> '
export MYSQL_PS1='\d> '

or once inside

prompt \d>\_
\R \d>\_

You can also convert by creating a dictionary of elements and then directly converting to a data frame:

import xml.etree.ElementTree as ET
import pandas as pd

# Contents of test.xml
# <?xml version="1.0" encoding="utf-8"?> <tags>   <row Id="1" TagName="bayesian" Count="4699" ExcerptPostId="20258" WikiPostId="20257" />   <row Id="2" TagName="prior" Count="598" ExcerptPostId="62158" WikiPostId="62157" />   <row Id="3" TagName="elicitation" Count="10" />   <row Id="5" TagName="open-source" Count="16" /> </tags>

root = ET.parse('test.xml').getroot()

tags = {"tags":[]}
for elem in root:
    tag = {}
    tag["Id"] = elem.attrib['Id']
    tag["TagName"] = elem.attrib['TagName']
    tag["Count"] = elem.attrib['Count']
    tags["tags"]. append(tag)

df_users = pd.DataFrame(tags["tags"])
df_users.head()

Everytime my MySQL starts, it will stop, then I noticed that some files are getting generated in C:\xampp\mysql\data. I tried deleting some files (like the Error logs, err file, etc.) on that directory. Back up first what you're going to delete to avoid losing data.

I don't know how it works. I'm just trying to enable HTTPS in my local machine but then suddenly MySQL can't be started. But now it's working.

I'm using Windows 10 and XAMPP 3.2.4.

The default condition can be anyplace within the switch that a case clause can exist. It is not required to be the last clause. I have seen code that put the default as the first clause. The case 2: gets executed normally, even though the default clause is above it.

As a test, I put the sample code in a function, called test(int value){} and ran:

  printf("0=%d\n", test(0));
  printf("1=%d\n", test(1));
  printf("2=%d\n", test(2));
  printf("3=%d\n", test(3));
  printf("4=%d\n", test(4));

The output is:

0=2
1=1
2=4
3=8
4=10

I found good solution myself. Since slick slider is still used nowadays i'll post my approach.

@RuivBoas answer is partly correct. - It can change the width of the slide but it can break the slider. Why?

Slick slider may exceed browser width. Actual container width is set to value that can accomodate all it's slides.

The best solution for setting slide width is to use width of the actual browser window. It works best with responsive design.

For example 2 slides with absorbed width

CSS

.slick-slide {
    width: 50vw;
    // for absorbing width from @Ken Wheeler answer
    box-sizing: border-box;
}

JS

$(document).on('ready', function () {
            $("#container").slick({
                variableWidth: true,
                slidesToShow: 2,
                slidesToScroll: 2
            });
        });

HTML markup

<div id="container">
    <div><img/></div>
    <div><img/></div>
    <div><img/></div>
</div>

These two lines of Bash will filter containers by some keywords before deleting them:

containers_to_keep=$(docker ps -a | grep 'keep\|Up\|registry:latest\|nexus' | awk '{ print $1 }')
containers_to_delete=$(docker ps -a | grep Exited | grep -Fv "$containers_to_keep" | awk '{ print $1 }')
docker rm $containers_to_delete

From this post.

Is there a js listener for when a user scrolls in a certain textbox that can be used?

DOM L3 UI Events spec gave the initial definition but is considered obsolete.

To add a single handler you can do:

  let isTicking;
  const debounce = (callback, evt) => {
    if (isTicking) return;
    requestAnimationFrame(() => {
      callback(evt);
      isTicking = false;
    });
    isTicking = true;
  };
  const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
  document.defaultView.onscroll = evt => debounce(handleScroll, evt);

For multiple handlers or, if preferable for style reasons, you may use addEventListener as opposed to assigning your handler to onscroll as shown above.

If using something like _.debounce from lodash you could probably get away with:

const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
document.defaultView.onscroll = evt => _.debounce(() => handleScroll(evt));

Review browser compatibility and be sure to test on some actual devices before calling it done.

Your problem is most likely with the video file, not the code. Your video is most likely not "safe for streaming". See where to place videos to stream android for more.

For Spring 5.2+ this works for me:

@PostMapping("/foo")
ResponseEntity<Void> foo(@PathVariable UUID fooId) {
    return fooService.findExam(fooId)
            .map(uri -> ResponseEntity.noContent().<Void>build())
            .orElse(ResponseEntity.notFound().build());
}

I've noticed that some Java libraries have started using META-INF as a directory in which to include configuration files that should be packaged and included in the CLASSPATH along with JARs. For example, Spring allows you to import XML Files that are on the classpath using:

<import resource="classpath:/META-INF/cxf/cxf.xml" />
<import resource="classpath:/META-INF/cxf/cxf-extensions-*.xml" />

In this example, I'm quoting straight out of the Apache CXF User Guide. On a project I worked on in which we had to allow multiple levels of configuration via Spring, we followed this convention and put our configuration files in META-INF.

When I reflect on this decision, I don't know what exactly would be wrong with simply including the configuration files in a specific Java package, rather than in META-INF. But it seems to be an emerging de facto standard; either that, or an emerging anti-pattern :-)

It is very easy to connect remote MySQL Server Using PHP, what you have to do is:

1. Create a MySQL User in remote server.

2. Give Full privilege to the User.

3. Connect to the Server using PHP Code (Sample Given Below)

$link = mysql_connect('your_my_sql_servername or IP Address', 'new_user_which_u_created', 'password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}

echo 'Connected successfully';

mysql_select_db('sandsbtob',$link) or die ("could not open db".mysql_error());
// we connect to localhost at port 3306

Use:

sb.AppendLine();
sb.Append("\t");

for better portability. Environment.NewLine may not necessarily be \n; Windows uses \r\n, for example.

Check this sample out from the Highcharts API.

Replace this

return Highcharts.dateFormat('%a %d %b', this.value);

With this

return Highcharts.dateFormat('%a %d %b %H:%M:%S', this.value);

Look here about the dateFormat() function.

>>> df = pd.DataFrame(columns=['col1', 'col2'])
>>> df = df.append(pd.Series(['a', 'b'], index=['col1','col2']), ignore_index=True)
>>> df = df.append(pd.Series(['d', 'e'], index=['col1','col2']), ignore_index=True) 
>>> df
  col1 col2

Does anyone have a more elegant solution?

Another possible solution, with usage of Array#reduce.

const arr = ["apple", "orange", "raspberry"];
const arr2 = [1, 2, 4];

const insert = (arr, item, index) =>
  arr.reduce(function(s, a, i) {
    i === index ? s.push(item, a) : s.push(a);
    return s;
  }, []); 

console.log(insert(arr, "banana", 1));
console.log(insert(arr2, 3, 2))

If you're using a Mac:

1. Start up Terminal Type "cd ~/" to go to your home folder

2. Type "touch .bash_profile" to create your new file.

3. Edit .bash_profile with your favorite editor (or you can just type "open -e .bash_profile" to open it in TextEdit).

4. Copy & Paste the below into the file:

function lazygit() {
    git add .
    git commit -a -m "$1"
    git push
}

After this, restart your terminal and simply add, commit and push in one easy command, example:

lazygit "This is my commit message"

This is based on @Macarse answer.

Use this to get the resources Id in a more faster and code friendly way.

public static int getId(String resourceName, Class<?> c) {
    try {
        Field idField = c.getDeclaredField(resourceName);
        return idField.getInt(idField);
    } catch (Exception e) {
        throw new RuntimeException("No resource ID found for: "
                + resourceName + " / " + c, e);
    }
}

Example:

getId("icon", R.drawable.class);

This worked for me:

ls -rt -d -1 $PWD/{*,.*}

I was not able to get this working entirely based on the suggestions above. Including the DataTypeAttribute [DataType(DataType.Date)] seemed to solve my issue, see:

The simplest way to get the substrings array from the given array is to use filter and includes:

myArray.filter(element => element.includes("substring"));

The above one will return an array of substrings.

myArray.find(element => element.includes("substring"));

The above one will return the first result element from the array.

myArray.findIndex(element => element.includes("substring"));

The above one will return the index of the first result element from the array.

What I did at the end was attach gdb to the process before it crashed, and then when it got the segfault I executed the generate-core-file command. That forced generation of a core dump.

I started using mocks with EasyMock. Easy enough to understand, but the replay step was kinda annoying. Mockito removes this, also has a cleaner syntax as it looks like readability was one of its primary goals. I cannot stress enough how important this is, since most of developers will spend their time reading and maintaining existing code, not creating it.

Another nice thing is that interfaces and implementation classes are handled in the same way, unlike in EasyMock where still you need to remember (and check) to use an EasyMock Class Extension.

I've taken a quick look at JMockit recently, and while the laundry list of features is pretty comprehensive, I think the price of this is legibility of resulting code, and having to write more.

For me, Mockito hits the sweet spot, being easy to write and read, and dealing with majority of the situations most code will require. Using Mockito with PowerMock would be my choice.

One thing to consider is that the tool you would choose if you were developing by yourself, or in a small tight-knit team, might not be the best to get for a large company with developers of varying skill levels. Readability, ease of use and simplicity would need more consideration in the latter case. No sense in getting the ultimate mocking framework if a lot of people end up not using it or not maintaining the tests.

fixed my agent string evaluation by scrubbing the string for LOWERCASE "iphone os 5_0" as opposed to "iPhone OS 5_0." now i am properly assigning iOS 5 specific classes to my html, when the uppercase scrub failed.

I met the issue before when using a fullscreen dialogFragment: there is always a padding while having set fullscreen. try this code in dialogFragment's onActivityCreated() method:

public void onActivityCreated(Bundle savedInstanceState)
{   
    super.onActivityCreated(savedInstanceState);
    Window window = getDialog().getWindow();
    LayoutParams attributes = window.getAttributes();
    //must setBackgroundDrawable(TRANSPARENT) in onActivityCreated()
    window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    if (needFullScreen)
    {
        window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    }
}

If you are using the animation listener, set v.setAnimationListener(null). Use the following code with all options.

v.getAnimation().cancel();
v.clearAnimation();
animation.setAnimationListener(null);

Try using ,

$('#points').val(request.responseText);

(Maybe helpful for others with a similar requirement)

I had a similar requirement to use AES-256-CBC encrypt and decrypt in Java.

To achieve (or specify) the 256-byte encryption/decryption, Java Cryptography Extension (JCE) policy should set to "Unlimited"

It can be set in the java.security file under $JAVA_HOME/jre/lib/security (for JDK) or $JAVA_HOME/lib/security (for JRE)

crypto.policy=unlimited

Or in the code as

Security.setProperty("crypto.policy", "unlimited");

Java 9 and later versions have this enabled by default.

Nope, you'll have to test each endpoint individually.

if ((x > 0) && (x < 10)) {
   // do stuff
}

Or if you want it to look more "betweeny", reorder the args:

if ((0 < x) && (x < 10)) {
   // do stuff
}

You probably get the error because your video path may be wrong in a way. Be sure your path is completely correct.

I spent a few hours on this too ... and agree that FLAG_ACTIVITY_CLEAR_TOP sounds like what you'd want: clear the entire stack, except for the activity being launched, so the Back button exits the application. Yet as Mike Repass mentioned, FLAG_ACTIVITY_CLEAR_TOP only works when the activity you're launching is already in the stack; when the activity's not there, the flag doesn't do anything.

What to do? Put the activity being launching in the stack with FLAG_ACTIVITY_NEW_TASK, which makes that activity the start of a new task on the history stack. Then add the FLAG_ACTIVITY_CLEAR_TOP flag.

Now, when FLAG_ACTIVITY_CLEAR_TOP goes to find the new activity in the stack, it'll be there and be pulled up before everything else is cleared.

Here's my logout function; the View parameter is the button to which the function's attached.

    startActivity(i);

In some cases it is possible to define a method or a constructor of class B in the header file of class A to resolve circular dependencies involving definitions. In this way you can avoid having to put definitions in .cc files, for example if you want to implement a header only library.

// file: a.h
#include "b.h"
struct A {
  A(const B& b) : _b(b) { }
  B get() { return _b; }
  B _b;
};

// note that the get method of class B is defined in a.h
A B::get() {
  return A(*this);
}

// file: b.h
class A;
struct B {
  // here the get method is only declared
  A get();
};

// file: main.cc
#include "a.h"
int main(...) {
  B b;
  A a = b.get();
}

Suppose the DataFrames you want to join are df1 and df2, and you are joining them on column 'a', then you have 2 methods

Method 1

df1.join(df2,'a','left_outer')

This is an awsome method and it is highly recommended.

Method 2

df1.join(df2,df1.a == df2.a,'left_outer').drop(df2.a)

I'm also going to assume that you mean "list" when you say "array." Sven Marnach's solution is good. If you are going to be doing repeated checks on the list, then it might be worth converting it to a set or frozenset, which can be faster for each check. Assuming your list of strs is called subjects:

subject_set = frozenset(subjects)
if query in subject_set:
    # whatever

VAR1=value1 VAR2=value2 myScript args ...

var name = $('#myElement').attr('name');

The easiest way to do in ubuntu (I tested in ubuntu-20.04):

Step 1. Open the file:

sudo nano /etc/apache2/apache2.conf

Step 2: Add the following line at the end of file:

Include /etc/phpmyadmin/apache.conf

Step 3: Restart apache2:

sudo systemctl restart apache2.service

Use d-flex instead of row for "tr" in Bootstrap 4

The thing is that "row" class takes more width then the parent container, which introduces issues.

Your code already contains a beautiful way to execute all statements from a specified sql file

# Open and read the file as a single buffer
fd = open('ZooDatabase.sql', 'r')
sqlFile = fd.read()
fd.close()

# all SQL commands (split on ';')
sqlCommands = sqlFile.split(';')

# Execute every command from the input file
for command in sqlCommands:
    # This will skip and report errors
    # For example, if the tables do not yet exist, this will skip over
    # the DROP TABLE commands
    try:
        c.execute(command)
    except OperationalError, msg:
        print "Command skipped: ", msg

Wrap this in a function and you can reuse it.

def executeScriptsFromFile(filename):
    # Open and read the file as a single buffer
    fd = open(filename, 'r')
    sqlFile = fd.read()
    fd.close()

    # all SQL commands (split on ';')
    sqlCommands = sqlFile.split(';')

    # Execute every command from the input file
    for command in sqlCommands:
        # This will skip and report errors
        # For example, if the tables do not yet exist, this will skip over
        # the DROP TABLE commands
        try:
            c.execute(command)
        except OperationalError, msg:
            print "Command skipped: ", msg

To use it

executeScriptsFromFile('zookeeper.sql')

You said you were confused by

result = c.execute("SELECT * FROM %s;" % table);

In Python, you can add stuff to a string by using something called string formatting.

You have a string "Some string with %s" with %s, that's a placeholder for something else. To replace the placeholder, you add % ("what you want to replace it with") after your string

ex:

a = "Hi, my name is %s and I have a %s hat" % ("Azeirah", "cool")
print(a)
>>> Hi, my name is Azeirah and I have a Cool hat

Bit of a childish example, but it should be clear.

Now, what

result = c.execute("SELECT * FROM %s;" % table);

means, is it replaces %s with the value of the table variable.

Emulation may seem daunting but is actually quite easier than simulating.

Any processor typically has a well-written specification that describes states, interactions, etc.

If you did not care about performance at all, then you could easily emulate most older processors using very elegant object oriented programs. For example, an X86 processor would need something to maintain the state of registers (easy), something to maintain the state of memory (easy), and something that would take each incoming command and apply it to the current state of the machine. If you really wanted accuracy, you would also emulate memory translations, caching, etc., but that is doable.

In fact, many microchip and CPU manufacturers test programs against an emulator of the chip and then against the chip itself, which helps them find out if there are issues in the specifications of the chip, or in the actual implementation of the chip in hardware. For example, it is possible to write a chip specification that would result in deadlocks, and when a deadline occurs in the hardware it's important to see if it could be reproduced in the specification since that indicates a greater problem than something in the chip implementation.

Of course, emulators for video games usually care about performance so they don't use naive implementations, and they also include code that interfaces with the host system's OS, for example to use drawing and sound.

Considering the very slow performance of old video games (NES/SNES, etc.), emulation is quite easy on modern systems. In fact, it's even more amazing that you could just download a set of every SNES game ever or any Atari 2600 game ever, considering that when these systems were popular having free access to every cartridge would have been a dream come true.

Whatever I understood from my learning and what I think it is is here. I am Quoting some part from a book i learnt this things. Nexus Repository Manager and Nexus Repository Manager OSS started as a repository manager supporting the Maven repository format. While it supports many other repository formats now, the Maven repository format is still the most common and well supported format for build and provisioning tools running on the JVM and beyond. This chapter shows example configurations for using the repository manager with Apache Maven and a number of other tools. The setups take advantage of merging many repositories and exposing them via a repository group. Setting this up is documented in the chapter in addition to the configuration used by specific tools.

Added data from link to avoid link rot..

put this at any Console application:

string.Format("{0,3}", CultureInfo.InstalledUICulture.Parent.LCID.ToString("X")).Replace(" ", "0");

Watch the result. At mine it was "016".

Then you go to the registry at this key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib

and create another one with the name you got from the string.Format result.

In my case:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\016"

and copy the info that is on any other key in this Perflib to this key you just created. Run the instalation again.

Update June 2019

What a dogs dinner. Unfortunately, the other answers didn't work for me.

For the most part, the official docker instructions for installing using a repository DID work.

sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

Followed by:

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

However, I had to modify the next command as follows (adding --nobest):

sudo yum install docker-ce --nobest

Finally, check the docker client:

docker --version
Docker version 18.09.7, build 2d0083d

Note also, the above works for standard RHEL AMI on AWS, but not for the Amazon Linux AMI type. May also find referencing this github issue insightful.

Added bonus, I found the following additional commands helpful:

Start the docker daemon:

sudo systemctl start docker.service

Give the current user (in my case ec2-user - check with whoami) rights to the docker group. This avoids running everything with sudo.

sudo usermod -aG docker $USER

Now, logoff and login again as same user as before (in my case ec2-user).

At this point, everything should be working. Check the docker daemon:

docker image ls
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

Using the following script, based on SLaks answer, I determined that the correct answer is:

echo The name of this file is: %~n0%~x0
echo The name of this file is: %~nx0

And here is my test script:

@echo off
echo %0
echo %~0
echo %n0
echo %x0
echo %~n0
echo %dp0
echo %~dp0
pause

What I find interesting is that %nx0 won't work, given that we know the '~' char usually is used to strip/trim quotes off of a variable.

actions in Vuex are asynchronous. The only way to let the calling function (initiator of action) to know that an action is complete - is by returning a Promise and resolving it later.

Here is an example: myAction returns a Promise, makes a http call and resolves or rejects the Promise later - all asynchronously

actions: {
    myAction(context, data) {
        return new Promise((resolve, reject) => {
            // Do something here... lets say, a http call using vue-resource
            this.$http("/api/something").then(response => {
                // http success, call the mutator and change something in state
                resolve(response);  // Let the calling function know that http is done. You may send some data back
            }, error => {
                // http failed, let the calling function know that action did not work out
                reject(error);
            })
        })
    }
}

Now, when your Vue component initiates myAction, it will get this Promise object and can know whether it succeeded or not. Here is some sample code for the Vue component:

export default {
    mounted: function() {
        // This component just got created. Lets fetch some data here using an action
        this.$store.dispatch("myAction").then(response => {
            console.log("Got some data, now lets show something in this component")
        }, error => {
            console.error("Got nothing from server. Prompt user to check internet connection and try again")
        })
    }
}

As you can see above, it is highly beneficial for actions to return a Promise. Otherwise there is no way for the action initiator to know what is happening and when things are stable enough to show something on the user interface.

And a last note regarding mutators - as you rightly pointed out, they are synchronous. They change stuff in the state, and are usually called from actions. There is no need to mix Promises with mutators, as the actions handle that part.

Edit: My views on the Vuex cycle of uni-directional data flow:

If you access data like this.$store.state["your data key"] in your components, then the data flow is uni-directional.

The promise from action is only to let the component know that action is complete.

The component may either take data from promise resolve function in the above example (not uni-directional, therefore not recommended), or directly from $store.state["your data key"] which is unidirectional and follows the vuex data lifecycle.

The above paragraph assumes your mutator uses Vue.set(state, "your data key", http_data), once the http call is completed in your action.

• name identifies form fields* ; so they can be shared by controls that stand to represent multiple possibles values for such a field (radio buttons, checkboxes). They will be submitted as keys for form values.
• id identifies DOM elements ; so they can be targeted by CSS or Javascript.

* names also used to identify local anchors, but this is deprecated and 'id' is a preferred way to do so nowadays.

Try adding this rule to the top of your htaccess:

RewriteEngine On
RewriteRule ^404/?$ /pages/errors/404.php [L]

Then under that (or any other rules that you have):

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^ http://domain.com/404/ [L,R]

You could do something like this

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:6740/api/Membership/exist");

req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";         
req.ContentLength = 6;

StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();

And then strReponse should contain the values returned by your webservice

var testAwait = function () {
    var promise = new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve('Inside test await');
        }, 1000);
    });
    return promise;
}

var asyncFunction = async function() {
    await testAwait().then((data) => {
        console.log(data);
    })
    return 'hello asyncFunction';
}

asyncFunction().then((data) => {
    console.log(data);
});

//Inside test await
//hello asyncFunction

Close: first you call ExcelFile, but then you call the .parse method and pass it the sheet name.

>>> xl = pd.ExcelFile("dummydata.xlsx")
>>> xl.sheet_names
[u'Sheet1', u'Sheet2', u'Sheet3']
>>> df = xl.parse("Sheet1")
>>> df.head()
                  Tid  dummy1    dummy2    dummy3    dummy4    dummy5  \

What you're doing is calling the method which lives on the class itself, rather than the instance, which is okay (although not very idiomatic), but if you're doing that you would also need to pass the sheet name:

>>> parsed = pd.io.parsers.ExcelFile.parse(xl, "Sheet1")
>>> parsed.columns
Index([u'Tid', u'dummy1', u'dummy2', u'dummy3', u'dummy4', u'dummy5', u'dummy6', u'dummy7', u'dummy8', u'dummy9'], dtype=object)

As mentioned in other answers, you can use the --filter option to limit the installed packages:

android update sdk --filter ...

The other answers don't mention that you can use constant string identifiers instead of indexes (which will change) for the filter options. This is helpful for unattended or scripted installs. Man for --filter option:

... This also accepts the identifiers returned by 'list sdk --extended'.

android list sdk --all --extended :

Packages available for installation or update: 97
----------
id: 1 or "tools"
     Type: Tool
     Desc: Android SDK Tools, revision 22.6.2
----------
id: 2 or "platform-tools"
     Type: PlatformTool
     Desc: Android SDK Platform-tools, revision 19.0.1
----------
id: 3 or "build-tools-19.0.3"
     Type: BuildTool
     Desc: Android SDK Build-tools, revision 19.0.3

Then you can use the string ids as the filter options to precisely specify the versions you want:

android update sdk --filter tools,platform-tools,build-tools-19.0.3 etc

This guy appears to have succeeded in having over 1 million concurrent connections on a single Node.js server.

It's not clear to me exactly how many ports he was using though.

Also, it`s interesting to set your PATH to reflect the JDK. After adding JAVA_HOME (which can be done with the example cited by 'mipadi'):

export JAVA_HOME=$(/usr/libexec/java_home)

Add also in ~/.profile:

export PATH=${JAVA_HOME}/bin:$PATH

P.S.: For OSX, I generally use .profile in the HOME dir instead of .bashrc

It can also be done this way:

figure(xx);
set(gcf, 'name', 'Name goes here')

gcf gets the current figure handle.

I used a combination of Attila Fulop (Lea Verou) solution for modern browsers and Gavin Brock solution for old browsers as follows:

if (history.pushState) {
    // IE10, Firefox, Chrome, etc.
    window.history.pushState(null, null, '#' + id);
} else {
    // IE9, IE8, etc
    window.location.hash = '#!' + id;
}

As observed by Gavin Brock, to capture the id back you will have to treat the string (which in this case can have or not the "!") as follows:

id = window.location.hash.replace(/^#!?/, '');

Before that, I tried a solution similar to the one proposed by user706270, but it did not work well with Internet Explorer: as its Javascript engine is not very fast, you can notice the scroll increase and decrease, which produces a nasty visual effect.

I don't understand why everyone is making this complicated (answers).

I'll just leave this here.

So above would be:

• Signal Unit: 4 bits
• Baud Rate [Signal Units per second]: 1000 Bd (baud)
• Bit Rate [Baud Rate * Signal Unit]: 4000 bps (bits per second)

Bit rate and Baud rate, these two terms are often used in data communication. Bit rate is simply the number of bits (i.e., 0’s and 1’s) transmitted per unit time. While Baud rate is the number of signal units transmitted per unit time that is needed to represent those bits.

In the latest version of ggplot2, this can be more easy.

p <- ggplot(mtcars, aes(wt, mpg))
p + geom_point()
p+ geom_point() + scale_x_continuous(expand = expansion(mult = c(0, 0))) + scale_y_continuous(expand = expansion(mult = c(0, 0)))

See ?expansion() for more details.

Exception : java.net.ConnectException

This means your request didn't getting response from server in stipulated time. And their are some reasons for this exception:

• Too many requests overloading the server
• Request packet loss because of wrong network configuration or line overload
• Sometimes firewall consume request packet before sever getting
• Also depends on thread connection pool configuration and current status of connection pool
• Response packet lost during transition

Greg is right-- you can use sys.stdout.write

Perhaps, though, you should consider refactoring your algorithm to accumulate a list of <whatevers> and then

lst = ['h', 'm']
print  "".join(lst)

I got the same error when I ran git status :

$ git status
On branch master
Your branch is ahead of 'origin/master' by 1 commit.
  (use "git push" to publish your local commits)
nothing to commit, working directory clean

To fix it I can run:

$ git push and run 
$ git push heroku master

I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.

By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.

Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.

The correct way is to set the BindByName property of OracleCommand to true as below:

var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;

You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post

Yes, you can.

From cplusplus.com:

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

   strm >> variable;

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

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

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

Just replace strm with cin.

1 Direct Execution / Conversion

Use from to directly convert a previously created Promise to an Observable.

import { from } from 'rxjs';

// getPromise() is called once, the promise is passed to the Observable
const observable$ = from(getPromise());

observable$ will be a hot Observable that effectively replays the Promises value to Subscribers.

It's a hot Observable because the producer (in this case the Promise) is created outside of the Observable. Multiple subscribers will share the same Promise. If the inner Promise has been resolved a new subscriber to the Observable will get its value immediately.

2 Deferred Execution On Every Subscribe

Use defer with a Promise factory function as input to defer the creation and conversion of a Promise to an Observable.

import { defer } from 'rxjs';

// getPromise() is called every time someone subscribes to the observable$
const observable$ = defer(() => getPromise());

observable$ will be a cold Observable.

It's a cold Observable because the producer (the Promise) is created inside of the Observable. Each subscriber will create a new Promise by calling the given Promise factory function.

This allows you to create an observable$ without creating and thus executing a Promise right away and without sharing this Promise with multiple subscribers. Each subscriber to observable$ effectively calls from(promiseFactory()).subscribe(subscriber). So each subscriber creates and converts its own new Promise to a new Observable and attaches itself to this new Observable.

3 Many Operators Accept Promises Directly

Most RxJS operators that combine (e.g. merge, concat, forkJoin, combineLatest ...) or transform observables (e.g. switchMap, mergeMap, concatMap, catchError ...) accept promises directly. If you're using one of them anyway you don't have to use from to wrap a promise first (but to create a cold observable you still might have to use defer).

// Execute two promises simultaneously
forkJoin(getPromise(1), getPromise(2)).pipe(
  switchMap(([v1, v2]) => v1.getPromise(v2)) // map to nested Promise
)

Check the documentation or implementation to see if the operator you're using accepts ObservableInput or SubscribableOrPromise.

type ObservableInput<T> = SubscribableOrPromise<T> | ArrayLike<T> | Iterable<T>;
// Note the PromiseLike ----------------------------------------------------v
type SubscribableOrPromise<T> = Subscribable<T> | Subscribable<never> | PromiseLike<T> | InteropObservable<T>;

The difference between from and defer in an example: https://stackblitz.com/edit/rxjs-6rb7vf

const getPromise = val => new Promise(resolve => {
  console.log('Promise created for', val);
  setTimeout(() => resolve(`Promise Resolved: ${val}`), 5000);
});

// the execution of getPromise('FROM') starts here, when you create the promise inside from
const fromPromise$ = from(getPromise('FROM'));
const deferPromise$ = defer(() => getPromise('DEFER'));

fromPromise$.subscribe(console.log);
// the execution of getPromise('DEFER') starts here, when you subscribe to deferPromise$
deferPromise$.subscribe(console.log);

There are a couple of possibilities. One I like uses a stringstream as a go-between:

std::ifstream t("file.txt");
std::stringstream buffer;
buffer << t.rdbuf();

Now the contents of "file.txt" are available in a string as buffer.str().

Another possibility (though I certainly don't like it as well) is much more like your original:

std::ifstream t("file.txt");
t.seekg(0, std::ios::end);
size_t size = t.tellg();
std::string buffer(size, ' ');
t.seekg(0);
t.read(&buffer[0], size); 

Officially, this isn't required to work under the C++98 or 03 standard (string isn't required to store data contiguously) but in fact it works with all known implementations, and C++11 and later do require contiguous storage, so it's guaranteed to work with them.

As to why I don't like the latter as well: first, because it's longer and harder to read. Second, because it requires that you initialize the contents of the string with data you don't care about, then immediately write over that data (yes, the time to initialize is usually trivial compared to the reading, so it probably doesn't matter, but to me it still feels kind of wrong). Third, in a text file, position X in the file doesn't necessarily mean you'll have read X characters to reach that point -- it's not required to take into account things like line-end translations. On real systems that do such translations (e.g., Windows) the translated form is shorter than what's in the file (i.e., "\r\n" in the file becomes "\n" in the translated string) so all you've done is reserved a little extra space you never use. Again, doesn't really cause a major problem but feels a little wrong anyway.

Yes, it is possible:

git clone https://github.com/pitosalas/st3_packages Packages 

You can specify the local root directory when using git clone.

<directory> 

The name of a new directory to clone into.
The "humanish" part of the source repository is used if no directory is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
Cloning into an existing directory is only allowed if the directory is empty.

As Chris comments, you can then rename that top directory.
Git only cares about the .git within said top folder, which you can get with various commands:

git rev-parse --show-toplevel git rev-parse --git-dir 

From this paper: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2049.pdf

for( type-speci?er-seq simple-declarator : expression ) statement

is syntactically equivalent to

{
    typedef decltype(expression) C;
    auto&& rng(expression);
    for (auto begin(std::For<C>::begin(rng)), end(std::For<C>::end(rng)); begin != end; ++ begin) {
        type-speci?er-seq simple-declarator(*begin);
        statement
    }
}

So you can clearly see that what is abc in your case will be std::pair<key_type, value_type >. So for printing you can do access each element by abc.first and abc.second

Usage:

control.InvokeIfRequired(c => c.Visible = false);

return control.InvokeIfRequired(c => {
    c.Visible = value

    return c.Visible;
});

Code:

using System;
using System.ComponentModel;

namespace Extensions
{
    public static class SynchronizeInvokeExtensions
    {
        public static void InvokeIfRequired<T>(this T obj, Action<T> action)
            where T : ISynchronizeInvoke
        {
            if (obj.InvokeRequired)
            {
                obj.Invoke(action, new object[] { obj });
            }
            else
            {
                action(obj);
            }
        }

        public static TOut InvokeIfRequired<TIn, TOut>(this TIn obj, Func<TIn, TOut> func) 
            where TIn : ISynchronizeInvoke
        {
            return obj.InvokeRequired
                ? (TOut)obj.Invoke(func, new object[] { obj })
                : func(obj);
        }
    }
}

Why use deflate instead of gzip for text files served by Apache?

The simple answer is don't.

RFC 2616 defines deflate as:

deflate The "zlib" format defined in RFC 1950 in combination with the "deflate" compression mechanism described in RFC 1951

The zlib format is defined in RFC 1950 as :

     0   1
     +---+---+
     |CMF|FLG|   (more-->)
     +---+---+

       0   1   2   3
     +---+---+---+---+
     |     DICTID    |   (more-->)
     +---+---+---+---+

     +=====================+---+---+---+---+
     |...compressed data...|    ADLER32    |
     +=====================+---+---+---+---+

So, a few headers and an ADLER32 checksum

RFC 2616 defines gzip as:

gzip An encoding format produced by the file compression program "gzip" (GNU zip) as described in RFC 1952 [25]. This format is a Lempel-Ziv coding (LZ77) with a 32 bit CRC.

RFC 1952 defines the compressed data as:

The format presently uses the DEFLATE method of compression but can be easily extended to use other compression methods.

CRC-32 is slower than ADLER32

Compared to a cyclic redundancy check of the same length, it trades reliability for speed (preferring the latter).

So ... we have 2 compression mechanisms that use the same algorithm for compression, but a different algorithm for headers and checksum.

Now, the underlying TCP packets are already pretty reliable, so the issue here is not Adler 32 vs CRC-32 that GZIP uses.

Turns out many browsers over the years implemented an incorrect deflate algorithm. Instead of expecting the zlib header in RFC 1950 they simply expected the compressed payload. Similarly various web servers made the same mistake.

So, over the years browsers started implementing a fuzzy logic deflate implementation, they try for zlib header and adler checksum, if that fails they try for payload.

The result of having complex logic like that is that it is often broken. Verve Studio have a user contributed test section that show how bad the situation is.

For example: deflate works in Safari 4.0 but is broken in Safari 5.1, it also always has issues on IE.

So, best thing to do is avoid deflate altogether, the minor speed boost (due to adler 32) is not worth the risk of broken payloads.

Build a new list with a list comprehension:

new_items = [x if x % 2 else None for x in items]

You can modify the original list in-place if you want, but it doesn't actually save time:

items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
for index, item in enumerate(items):
    if not (item % 2):
        items[index] = None

Here are (Python 3.6.3) timings demonstrating the non-timesave:

In [1]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: for index, item in enumerate(items):
   ...:     if not (item % 2):
   ...:         items[index] = None
   ...:
1.06 µs ± 33.7 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [2]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: new_items = [x if x % 2 else None for x in items]
   ...:
891 ns ± 13.6 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

And Python 2.7.6 timings:

In [1]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: for index, item in enumerate(items):

   ...:         items[index] = None
   ...:

In [2]: %%timeit
   ...: items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   ...: new_items = [x if x % 2 else None for x in items]
   ...: 
1000000 loops, best of 3: 1.14 µs per loop

For editing Excel files from within a C# application, I recently started using NPOI. I'm very satisfied with it.

Getting a standalone month name is surprisingly difficult to perform "right" in Java. (At least as of this writing. I'm currently using Java 8).

The problem is that in some languages, including Russian and Czech, the standalone version of the month name is different from the "formatting" version. Also, it appears that no single Java API will just give you the "best" string. The majority of answers posted here so far only offer the formatting version. Pasted below is a working solution for getting the standalone version of a single month name, or getting an array with all of them.

I hope this saves someone else some time!

The answer by @Mobilpadde is nice. But this is my solution with regex using preg_replace which might be faster according to my tests.

echo preg_replace('/<br\s?\/?>/i', "\r\n", "testing<br/><br /><BR><br>");

function function_one() {
    preg_replace('/<br\s?\/?>/i', "\r\n", "testing<br/><br /><BR><br>");
}

function function_two() {
    str_ireplace(['<br />','<br>','<br/>'], "\r\n", "testing<br/><br /><BR><br>");
}

function benchmark() {
    $count = 10000000;
    $before = microtime(true);

    for ($i=0 ; $i<$count; $i++) {
        function_one();
    }

    $after = microtime(true);
    echo ($after-$before)/$i . " sec/function one\n";



    $before = microtime(true);

    for ($i=0 ; $i<$count; $i++) {
        function_two();
    }

    $after = microtime(true);
    echo ($after-$before)/$i . " sec/function two\n";
}
benchmark();

Results:

1.1471637010574E-6 sec/function one (preg_replace)
1.6027762889862E-6 sec/function two (str_ireplace)

Most of the time your background color is different from the background of your table. Since there are spaces between the cells, those spaces will create the illusion of lines with the color of the background behind the table.

The solution is to get rid of those spaces.

Inside the table tag write:

cellspacing="0"

Since v-ref is no longer a directive, but a special attribute, it can also be dynamically defined. This is especially useful in combination with v-for.

For example:

<ul>
    <li v-for="(item, key) in items" v-on:click="play(item,$event)">
        <a v-bind:ref="'key' + item.id" v-bind:href="item.url">
            <!-- content -->
        </a>
    </li>
</ul>

and in Vue component you can use

var recordingModel = new Vue({
  el:'#rec-container',
  data:{
    items:[]
  },

  methods:{
    play:function(key,e){
      // it contains the bound reference
      console.log(this.$refs['item'+key]);
    }
  }
});

If you are using virtualenv, it is not as trivial to get the driver using the installer. What you can do then: install it as described by Devon. Then copy over cx_Oracle.pyd and the cx_Oracle-XXX.egg-info folder from Python\Lib\site-packages into the Lib\site-packages from your virtual env. Of course, also here, architecture and version are important.

Matthew's supremely efficient script updated to use the dm_exec_sessions DMV, replacing the deprecated sysprocesses system table:

USE [master];
GO

DECLARE @Kill VARCHAR(8000) = '';

SELECT
    @Kill = @Kill + 'kill ' + CONVERT(VARCHAR(5), session_id) + ';'
FROM
    sys.dm_exec_sessions
WHERE
    database_id = DB_ID('<YourDB>');

EXEC sys.sp_executesql @Kill;

Alternative using WHILE loop (if you want to process any other operations per execution):

USE [master];
GO

DECLARE @DatabaseID SMALLINT = DB_ID(N'<YourDB>');    
DECLARE @SQL NVARCHAR(10);

WHILE EXISTS ( SELECT
                1
               FROM
                sys.dm_exec_sessions
               WHERE
                database_id = @DatabaseID )    
    BEGIN;
        SET @SQL = (
                    SELECT TOP 1
                        N'kill ' + CAST(session_id AS NVARCHAR(5)) + ';'
                    FROM
                        sys.dm_exec_sessions
                    WHERE
                        database_id = @DatabaseID
                   );
        EXEC sys.sp_executesql @SQL;

I usually use a function to validate my post and it is an answer for this question too so let me post it.

to call my function I will use the 2 array like this

validatePost(['username', 'password', 'any other field'], $_POST))

then my function will look like this

 function validatePost($requiredFields, $post)
    {
        $validation = [];

        foreach($requiredFields as $required => $key)
        {
            if(!array_key_exists($key, $post))
            {
                $validation['required'][] = $key;
            }
        }

        return $validation;
    }

this will output this

"required": [ "username", "password", "any other field" ]

so what this function does is validate and return all the missing fields of the post request.

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

Share and enjoy.

Just for fun I took Siddharth's suggestion of separate textboxes and did comboboxes. If anybody's interested, add a userform with three comboboxes named cboDay, cboMonth and cboYear and arrange them left to right. Then paste the code below into the UserForm's code module. The required combobox properties are set in UserFormInitialization, so no additional prep should be required.

The tricky part is changing the day when it becomes invalid because of a change in year or month. This code just resets it to 01 when that happens and highlights cboDay.

I haven't coded anything like this in a while. Hopefully it will be of interest to somebody, someday. If not it was fun!

No, Integer and String are different types. To convert an integer to string use: String.valueOf(integer), or Integer.toString(integer) for primitive, or Integer.toString() for the object.

If you can't change the datatype on the table itself to use varchar(max), then change your query to this:

SELECT *
FROM   [Village]
WHERE  CONVERT(VARCHAR(MAX), [CastleType]) = 'foo'

Ditch FileWriter and FileReader, which are useless exactly because they do not allow you to specify the encoding. Instead, use

new OutputStreamWriter(new FileOutputStream(file), StandardCharsets.UTF_8)

and

new InputStreamReader(new FileInputStream(file), StandardCharsets.UTF_8);

that syntax is now deprecated, you will get this error:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 14: Expected a stage @ line 14, column 9.
       parallel firstTask: {
       ^

WorkflowScript: 14: Stage does not have a name @ line 14, column 9.
       parallel secondTask: {
       ^

2 errors

You should do something like:

stage("Parallel") {
    steps {
        parallel (
            "firstTask" : {
                //do some stuff
            },
            "secondTask" : {
                // Do some other stuff in parallel
            }
        )
    }
}

Just to add the use of node here, to distribute jobs across multiple build servers/ VMs:

pipeline {
  stages {
    stage("Work 1"){
     steps{
      parallel ( "Build common Library":   
            {
              node('<Label>'){
                  /// your stuff
                  }
            },

        "Build Utilities" : {
            node('<Label>'){
               /// your stuff
              }
           }
         )
    }
}

All VMs should be labelled as to use as a pool.

Your local JVM or remote server may not have the required ciphers. go here

https://www.oracle.com/java/technologies/javase-jce8-downloads.html

and download the zip file that contains: US_export_policy.jar and local_policy.jar

replace the existing files (you need to find the existing path in your JVM).

on a Mac, my path was here. /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/lib/security

this worked for me.

From Hadoop page,

start-all.sh 

This will startup a Namenode, Datanode, Jobtracker and a Tasktracker on your machine.

start-dfs.sh

This will bring up HDFS with the Namenode running on the machine you ran the command on. On such a machine you would need start-mapred.sh to separately start the job tracker

start-all.sh/stop-all.sh has to be run on the master node

You would use start-all.sh on a single node cluster (i.e. where you would have all the services on the same node.The namenode is also the datanode and is the master node).

In multi-node setup,

You will use start-all.sh on the master node and would start what is necessary on the slaves as well.

Alternatively,

Use start-dfs.sh on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file.

Use start-mapred.sh on the machine you plan to run the Jobtracker on. This will bring up the Map/Reduce cluster with Jobtracker running on the machine you ran the command on and Tasktrackers running on machines listed in the slaves file.

hadoop-daemon.sh as stated by Tariq is used on each individual node. The master node will not start the services on the slaves.In a single node setup this will act same as start-all.sh.In a multi-node setup you will have to access each node (master as well as slaves) and execute on each of them.

Have a look at this start-all.sh it call config followed by dfs and mapred

Add this to your main CSS:

table td {
    border-top: none !important;
}

Use this for newer versions of bootstrap:

.table th, .table td { 
     border-top: none !important; 
 }

According to the Python documentation:

The sequence

prog = re.compile(pattern)
result = prog.match(string)

is equivalent to

result = re.match(pattern, string)

but using re.compile() and saving the resulting regular expression object for reuse is more efficient when the expression will be used several times in a single program.

So my conclusion is, if you are going to match the same pattern for many different texts, you better precompile it.

Use array_combine() to fuse the arrays together and iterate over the result.

$countries = array_combine($codes, $names);

It doesn't work on Ubuntu 16.04, it seems that some libraries have been forgotten in the python installation package on this one. You should use package manager instead.

Solution

Uninstall matplotlib from pip then install it again with apt-get

python 2:

sudo pip uninstall matplotlib
sudo apt-get install python-matplotlib

python 3:

sudo pip3 uninstall matplotlib
sudo apt-get install python3-matplotlib

Why Not something more direct like:

Dim x = context.MyTable.Max(Function(DataItem) DataItem.MyField = Value)

Repair the database by your domain provider cpanel.

Or see if you didnt merged something in the phpMyAdmin

Is the maximum recommended title length really 50?

I have believed this for years, but as I just noticed the documentation of "git commit" actually states

$ git help commit | grep -C 1 50
      Though not required, it’s a good idea to begin the commit message with
      a single short (less than 50 character) line summarizing the change,
      followed by a blank line and then a more thorough description. The text

$  git version
git version 2.11.0

One could argue that "less then 50" can only mean "no longer than 49".

Another simple example.

For this sample we can use 100x100 DIV-box:

<div id="box" style="width: 100px; height: 100px; border: solid 1px red;">
 // Red box contents here...
</div>

And small jQuery trick:

<script type="text/javascript">
  jQuery("#box").bind("resize", function() {
    alert("Box was resized from 100x100 to 200x200");
  });
  jQuery("#box").width(200).height(200).trigger("resize");
</script>

Steps:

1. We created DIV block element for resizing operatios
2. Add simple JavaScript code with:
   • jQuery bind
   • jQuery resizer with trigger action "resize" - trigger is most important thing in my example
3. After resize you can check the browser alert information

That's all. ;-)

1. First find out the Procees id (pid) which has occupied the required port.(e.g 5434)

   ps aux | grep 5434

2.kill that process

   kill -9 <pid>

      beforeShow: function(el) {
            if ( el.getAttribute("readonly") !== null ) {
                if ( (el.value == null) || (el.value == '') ) {
                    $(el).datepicker( "option", "minDate", +1 );
                    $(el).datepicker( "option", "maxDate", -1 );
                } else {
                    $(el).datepicker( "option", "minDate", el.value );
                    $(el).datepicker( "option", "maxDate", el.value );
                }
            }
        },

Why your code does not work?

The where method returns an ActiveRecord::Relation object (acts like an array which contains the results of the where), it can be empty but it will never be nil.

Business.where(id: -1) 
 #=> returns an empty ActiveRecord::Relation ( similar to an array )
Business.where(id: -1).nil? # ( similar to == nil? )
 #=> returns false
Business.where(id: -1).empty? # test if the array is empty ( similar to .blank? )
 #=> returns true

How to test if at least one record exists?

Option 1: Using .exists?

if Business.exists?(user_id: current_user.id)
  # same as Business.where(user_id: current_user.id).exists?
  # ...
else
  # ...
end

Option 2: Using .present? (or .blank?, the opposite of .present?)

if Business.where(:user_id => current_user.id).present?
  # less efficiant than using .exists? (see generated SQL for .exists? vs .present?)
else
  # ...
end

Option 3: Variable assignment in the if statement

if business = Business.where(:user_id => current_user.id).first
  business.do_some_stuff
else
  # do something else
end

This option can be considered a code smell by some linters (Rubocop for example).

Option 3b: Variable assignment

business = Business.where(user_id: current_user.id).first
if business
  # ...
else
  # ...
end

You can also use .find_by_user_id(current_user.id) instead of .where(...).first

Best option:

• If you don't use the Business object(s): Option 1
• If you need to use the Business object(s): Option 3

My Mapper implementation classes in my target folder had been deleted, so my Mapper interfaces had no implementation classes anymore. Thus I got the same error Field *** required a bean of type ***Mapper that could not be found.

I simply had to regenerate my mappers implementations with maven, and refresh the project...

This is from MSDN sample:

(*.bmp, *.jpg)|*.bmp;*.jpg

So for your case

openFileDialog1.Filter = "JPG (*.jpg,*.jpeg)|*.jpg;*.jpeg|TIFF (*.tif,*.tiff)|*.tif;*.tiff"

You'll find it in the AppData folder if you choose to install it in the default location. Otherwise, it will be located at the folder where you installed your Android SDK/platform-tools folder.

There is no function overloading in Python, meaning that you can't have multiple functions with the same name but different arguments.

In your code example, you're not overloading __init__(). What happens is that the second definition rebinds the name __init__ to the new method, rendering the first method inaccessible.

As to your general question about constructors, Wikipedia is a good starting point. For Python-specific stuff, I highly recommend the Python docs.

As Kevin points out, URL Schemes are the only way to communicate between apps. So, no, it's not possible to launch arbitrary apps.

But it is possible to launch any app that registers a URL Scheme, whether it's Apple's, yours, or another developer's. The docs are here:

Defining a Custom URL Scheme for Your App

As for launching the phone, looks like your tel: link needs to have least three digits before the phone will launch. So you can't just drop into the app without dialing a number.

Python has a ternary form for assignments; however there may be even a shorter form that people should be aware of.

It's very common to need to assign to a variable one value or another depending on a condition.

>>> li1 = None
>>> li2 = [1, 2, 3]
>>> 
>>> if li1:
...     a = li1
... else:
...     a = li2
...     
>>> a
[1, 2, 3]

^ This is the long form for doing such assignments.

Below is the ternary form. But this isn't most succinct way - see last example.

>>> a = li1 if li1 else li2
>>> 
>>> a
[1, 2, 3]
>>> 

With Python, you can simply use or for alternative assignments.

>>> a = li1 or li2
>>> 
>>> a
[1, 2, 3]
>>> 

The above works since li1 is None and the interp treats that as False in logic expressions. The interp then moves on and evaluates the second expression, which is not None and it's not an empty list - so it gets assigned to a.

This also works with empty lists. For instance, if you want to assign a whichever list has items.

>>> li1 = []
>>> li2 = [1, 2, 3]
>>> 
>>> a = li1 or li2
>>> 
>>> a
[1, 2, 3]
>>> 

Knowing this, you can simply such assignments whenever you encounter them. This also works with strings and other iterables. You could assign a whichever string isn't empty.

>>> s1 = ''
>>> s2 = 'hello world'
>>> 
>>> a = s1 or s2
>>> 
>>> a
'hello world'
>>> 

I always liked the C ternary syntax, but Python takes it a step further!

I understand that some may say this isn't a good stylistic choice because it relies on mechanics that aren't immediately apparent to all developers. I personally disagree with that viewpoint. Python is a syntax rich language with lots of idiomatic tricks that aren't immediately apparent to the dabler. But the more you learn and understand the mechanics of the underlying system, the more you appreciate it.

As @Ninefingers mentioned, pthreads are unix-only. Posix only, really.

That said, Microsoft does have a library that duplicates pthreads:

max is a builtin function in python, which is used to get max value from a sequence, i.e (list, tuple, set, etc..)

print(max([9, 7, 12, 5]))

# prints 12 

try this:

/////// Controller post and get simple text value 
[HttpPost]
    public string Contact(string message)
    { 
        return "<h1>Hi,</h1>we got your message, <br />" + message + " <br />Thanks a lot";
    }

//// in the view add reference to the Javascript (jQuery) files

@section Scripts{

<script src="~/Scripts/modernizr-2.6.2.js"></script>
<script src="~/Scripts/jquery-1.8.2.intellisense.js"></script>
<script src="~/Scripts/jquery-1.8.2.js"></script>
<script src="~/Scripts/jquery-1.8.2.min.js"></script>  
}

/// then add the Post method as following:

<script type="text/javascript"> 

/// post and get text value
    
$("#send").on("click", function () {    
$.post('', { message: $('#msg').val() })  

//// empty post('') means post to the default controller, 
///we are not pacifying different action or controller
/// however we can define a url as following:
/// var url = "@(Url.Action("GetDataAction", "GetDataController"))"

         .done(function (response) {
             $("#myform").html(response);
        })
        .error(function () { alert('Error') })
        .success(function () { alert('OK') })
        return false;
    }); 

Now let's say you want to do it using $.Ajax and JSON:

// Post JSON data  add using System.Net;
    [HttpPost]
    public JsonResult JsonFullName(string fname, string lastname)
    {
        var data = "{ \"fname\" : \"" + fname  + " \" , \"lastname\" : \"" + lastname + "\" }";
//// you have to add the JsonRequestBehavior.AllowGet 
 //// otherwise it will throw an exception on run-time.
        return Json(data, JsonRequestBehavior.AllowGet);  
    }

Then, inside your view: add the event click on a an input of type button, or even a from submit: Just make sure your JSON data is well formatted.

  $("#jsonGetfullname").on("click", function () { 
        $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: "@(Url.Action("JsonFullName", "Home"))",
            data: "{ \"fname\" : \"Mahmoud\" , \"lastname\" : \"Sayed\" }",
            dataType: "json",
            success: function (data) {
                var res = $.parseJSON(data);
                $("#myform").html("<h3>Json data: <h3>" + res.fname + ", " + res.lastname)
            }, 
            error: function (xhr, err) {
                alert("readyState: " + xhr.readyState + "\nstatus: " + xhr.status);
                alert("responseText: " + xhr.responseText);
            } 
        })
    });

Consider adding this to your CSS to resolve the problem:

button {
    margin: 0 auto;
    display: block;
}

It is possible that in python 2.7 pip is installed by default. if it is not then you can execute

python -m ensurepip --default-pip

This worked for me.

Well, I am still stumped. So here is more code.

Before I leave my map, I call SaveLocation(myMapView,myMapController); This is what ends up calling my geocoding information.

But since getFromLocation can throw an IOException, I had to do the following to call SaveLocation

try
{
    SaveLocation(myMapView,myMapController);
}
catch (IOException e) 
{
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Then I have to change SaveLocation by saying it throws IOExceptions :

 public void SaveLocation(MapView mv, MapController mc) throws IOException{
    //I do this : 
    Geocoder myLocation = new Geocoder(getApplicationContext(), Locale.getDefault());   
    List myList = myLocation.getFromLocation(latPoint, lngPoint, 1);
//...
    }

And it crashes every time.

JavaScript is always synchronous and single-threaded. If you're executing a JavaScript block of code on a page then no other JavaScript on that page will currently be executed.

JavaScript is only asynchronous in the sense that it can make, for example, Ajax calls. The Ajax call will stop executing and other code will be able to execute until the call returns (successfully or otherwise), at which point the callback will run synchronously. No other code will be running at this point. It won't interrupt any other code that's currently running.

JavaScript timers operate with this same kind of callback.

Describing JavaScript as asynchronous is perhaps misleading. It's more accurate to say that JavaScript is synchronous and single-threaded with various callback mechanisms.

jQuery has an option on Ajax calls to make them synchronously (with the async: false option). Beginners might be tempted to use this incorrectly because it allows a more traditional programming model that one might be more used to. The reason it's problematic is that this option will block all JavaScript on the page until it finishes, including all event handlers and timers.

MySQL multiple instances present on Ubuntu.

step 1 : if it's listed as installed, you got it. Else you need to get it.

sudo ps -A | grep mysql

step 2 : remove the one MySQL

sudo apt-get remove mysql

sudo service mysql restart

step 3 : restart lamp

sudo /opt/lampp/lampp restart

Try the following:

sudo rm /var/lib/mongodb/mongod.lock
sudo service mongodb restart

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

var table;

$(document).ready(function() {

    //datatables
    table = $('#userTable').DataTable({ 

        "processing": true, //Feature control the processing indicator.
        "serverSide": true, //Feature control DataTables' server-side processing mode.
        "order": [], //Initial no order.
         "aaSorting": [],
        // Load data for the table's content from an Ajax source
        "ajax": {
            "url": "<?php echo base_url().'admin/ajax_list';?>",
            "type": "POST"
        },

        //Set column definition initialisation properties.
        "columnDefs": [
        { 
            "targets": [ ], //first column / numbering column
            "orderable": false, //set not orderable
        },
        ],

    });

});

set

"targets": [0]

to

 "targets": [ ]

That would just be:

 Console.WriteLine(Variables.name);

and it needs to be public also:

public class Variables
{
   public static string name = "";
}

You can use https://github.com/keighl/KTCenterFlowLayout like this:

KTCenterFlowLayout *layout = [[KTCenterFlowLayout alloc] init];

[self.collectionView setCollectionViewLayout:layout];

 ssh user@machine 'bash -s' < local_script.sh

or you can just

 ssh user@machine "remote command to run" 

It's very simple.

The checkbox field is like an input text. If you don't write anything in the field, it will say the field doesn't exist.

<form method="post">
    <input type="checkbox" name="check">This is how it works!<br>
    <button type="submit" name="submit">Submit</button>
</form>
<?php
if(isset($_POST['submit'])) {
    if(!isset($_POST['check'])) {
        echo "Not selected!";
    }else{
        echo "Selected!";
    }
}
?>
