While other suggested solutions work, If you really want the solution to be made thread safe you should replace ArrayList with CopyOnWriteArrayList

    //List<String> s = new ArrayList<>(); //Will throw exception
    List<String> s = new CopyOnWriteArrayList<>();
    s.add("B");
    Iterator<String> it = s.iterator();
    s.add("A");

    //Below removes only "B" from List
    while (it.hasNext()) {
        s.remove(it.next());
    }
    System.out.println(s);

Why can't we create Object of Abstract Class ? When we create a pure virtual function in Abstract class, we reserve a slot for a function in the VTABLE(studied in last topic), but doesn't put any address in that slot. Hence the VTABLE will be incomplete. As the VTABLE for Abstract class is incomplete, hence the compiler will not let the creation of object for such class and will display an errror message whenever you try to do so.

Pure Virtual definitions

Pure Virtual functions can be given a small definition in the Abstract class, which you want all the derived classes to have. Still you cannot create object of Abstract class. Also, the Pure Virtual function must be defined outside the class definition. If you will define it inside the class definition, complier will give an error. Inline pure virtual definition is Illegal.

Use the .Clear method.

MSDN documentation here.

This is a way to do it where the syntax is simpler for me to understand:

yourfilenames=`ls ./*.txt`
for eachfile in $yourfilenames
do
   echo $eachfile
done

./ is the current working directory but could be replaced with any path
*.txt returns anything.txt
You can check what will be listed easily by typing the ls command straight into the terminal.

Basically, you create a variable yourfilenames containing everything the list command returns as a separate element, and then you loop through it. The loop creates a temporary variable eachfile that contains a single element of the variable it's looping through, in this case a filename. This isn't necessarily better than the other answers, but I find it intuitive because I'm already familiar with the ls command and the for loop syntax.

Quick fix:

position: relative;
top: -12px;
left: -2px;

this should balance out those offsets, but maybe you should take a look at your whole layout and see how that box interacts with other boxes.

As for terminology, left, right, top and bottom are CSS offset properties. They are used for positioning elements at a specific location (when used with absolute or fixed positioning), or to move them relative to their default location (when used with relative positioning). Margins on the other hand specify gaps between boxes and they sometimes collapse, so they can't be reliably used as offsets.

But note that in your case that offset may not be computed (solely) from CSS offsets.

Try the below code for delay

//MARK: First Way

func delayForWork() {
    delay(3.0) {
        print("delay for 3.0 second")
    }
}

delayForWork()

// MARK: Second Way

DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
    // your code here delayed by 0.5 seconds
}

Use java.lang.String.format(String,Object...) like this:

String.format("%05d", yournumber);

for zero-padding with a length of 5. For hexadecimal output replace the d with an x as in "%05x".

The full formatting options are documented as part of java.util.Formatter.

I use following code, found somewhere in the internet don't remember the source though.

    var allText;
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function () {
        if (rawFile.readyState === 4) {
            if (rawFile.status === 200 || rawFile.status == 0) {
                allText = rawFile.responseText;
            }
        }
    }
    rawFile.send(null);
    return JSON.parse(allText);

uint i = 10;
int j = (int)i;

or

int k = Convert.ToInt32(i)

You can also use js map function:

$("#multipleSelect :selected").map(function(i, el) {
    return $(el).val();
}).get();

And then you can get any property of the option element:

return $(el).text();
return $(el).data("mydata");
return $(el).prop("disabled");
etc...

The selected answer is absolutely correct, however it did not leave me with the latest commit/pushes ...

So for me:

git reset --hard dev/jobmanager-tools
git pull  ( did not work as git was not sure what branch i wanted)

Since I know I want to temporarily set my upstream branch for a few weeks to a specific branch ( same as the one i switched to / checked out earlier and did a hard reset on )

So AFTER reset

git branch --set-upstream-to=origin/dev/jobmanager-tools
git pull
git status    ( says--> on branch  dev/jobmanager-tools 

To improve on Ryan's answer:

CGFloat oldWidth = image.size.width;
        CGFloat oldHeight = image.size.height;

//You may need to take some retina adjustments into consideration here
        CGFloat scaleFactor = (oldWidth > oldHeight) ? width / oldWidth : height / oldHeight;

return [UIImage imageWithCGImage:image.CGImage scale:scaleFactor orientation:UIImageOrientationUp];

Share your folder for "everyone" or some specific group and try this:

You can do it in Java 6:

Set<String> h = new HashSet<String>(Arrays.asList("a", "b", "c"));

But why? I don't find it to be more readable than explicitly adding elements.

There are two ways to know the about Sybase version,

1) Using this System procedure to get the information about Sybase version

2) Using this command to get Sybase version

Repeatable Read

The state of the database is maintained from the start of the transaction. If you retrieve a value in session1, then update that value in session2, retrieving it again in session1 will return the same results. Reads are repeatable.

session1> BEGIN;
session1> SELECT firstname FROM names WHERE id = 7;
Aaron

session2> BEGIN;
session2> SELECT firstname FROM names WHERE id = 7;
Aaron
session2> UPDATE names SET firstname = 'Bob' WHERE id = 7;
session2> SELECT firstname FROM names WHERE id = 7;
Bob
session2> COMMIT;

session1> SELECT firstname FROM names WHERE id = 7;
Aaron

Read Committed

Within the context of a transaction, you will always retrieve the most recently committed value. If you retrieve a value in session1, update it in session2, then retrieve it in session1again, you will get the value as modified in session2. It reads the last committed row.

session1> BEGIN;
session1> SELECT firstname FROM names WHERE id = 7;
Aaron

session2> BEGIN;
session2> SELECT firstname FROM names WHERE id = 7;
Aaron
session2> UPDATE names SET firstname = 'Bob' WHERE id = 7;
session2> SELECT firstname FROM names WHERE id = 7;
Bob
session2> COMMIT;

session1> SELECT firstname FROM names WHERE id = 7;
Bob

Makes sense?

Here's a simple function that creates a CSS color string from RGB values ranging from 0 to 255:

function rgb(r, g, b){
  return "rgb("+r+","+g+","+b+")";
}

Alternatively (to create fewer string objects), you could use array join():

function rgb(r, g, b){
  return ["rgb(",r,",",g,",",b,")"].join("");
}

The above functions will only work properly if (r, g, and b) are integers between 0 and 255. If they are not integers, the color system will treat them as in the range from 0 to 1. To account for non-integer numbers, use the following:

function rgb(r, g, b){
  r = Math.floor(r);
  g = Math.floor(g);
  b = Math.floor(b);
  return ["rgb(",r,",",g,",",b,")"].join("");
}

You could also use ES6 language features:

const rgb = (r, g, b) => 
  `rgb(${Math.floor(r)},${Math.floor(g)},${Math.floor(b)})`;

how do pass this clicked products from first controller to second?

On click you can call method that invokes broadcast:

$rootScope.$broadcast('SOME_TAG', 'your value');

and the second controller will listen on this tag like:

$scope.$on('SOME_TAG', function(response) {
      // ....
})

Since we can't inject $scope into services, there is nothing like a singleton $scope.

But we can inject $rootScope. So if you store value into the Service, you can run $rootScope.$broadcast('SOME_TAG', 'your value'); in the Service body. (See @Charx description about services)

app.service('productService',  function($rootScope) {/*....*/}

Please check good article about $broadcast, $emit

If you are working a lot with graphs and ggplot, you might be tired to add the theme() each time. If you don't want to change the default theme as suggested earlier, you may find easier to create your own personal theme.

personal_theme = theme(plot.title = 
element_text(hjust = 0.5))

Say you have multiple graphs, p1, p2 and p3, just add personal_theme to them.

p1 + personal_theme
p2 + personal_theme
p3 + personal_theme

dat <- data.frame(
  time = factor(c("Lunch","Dinner"), 
levels=c("Lunch","Dinner")),
  total_bill = c(14.89, 17.23)
)
p1 = ggplot(data=dat, aes(x=time, y=total_bill, 
fill=time)) + 
  geom_bar(colour="black", fill="#DD8888", 
width=.8, stat="identity") + 
  guides(fill=FALSE) +
  xlab("Time of day") + ylab("Total bill") +
  ggtitle("Average bill for 2 people")

p1 + personal_theme

UTF

UTF is a family of multi-byte encoding schemes that can represent Unicode code points which can be representative of up to 2^31 [roughly 2 billion] characters. UTF-8 is a flexible encoding system that uses between 1 and 4 bytes to represent the first 2^21 [roughly 2 million] code points.

Long story short: any character with a code point/ordinal representation below 127, aka 7-bit-safe ASCII is represented by the same 1-byte sequence as most other single-byte encodings. Any character with a code point above 127 is represented by a sequence of two or more bytes, with the particulars of the encoding best explained here.

ISO-8859

ISO-8859 is a family of single-byte encoding schemes used to represent alphabets that can be represented within the range of 127 to 255. These various alphabets are defined as "parts" in the format ISO-8859-n, the most familiar of these likely being ISO-8859-1 aka 'Latin-1'. As with UTF-8, 7-bit-safe ASCII remains unaffected regardless of the encoding family used.

The drawback to this encoding scheme is its inability to accommodate languages comprised of more than 128 symbols, or to safely display more than one family of symbols at one time. As well, ISO-8859 encodings have fallen out of favor with the rise of UTF. The ISO "Working Group" in charge of it having disbanded in 2004, leaving maintenance up to its parent subcommittee.

I think Chris Coyier has solution for that hashing problem, have a look at his screencast:

Best Practices with Dynamic Content

With Spring 4.1 and above, you can return pretty much anything (such as pictures, pdfs, documents, jars, zips, etc) quite simply without any extra dependencies. For example, the following could be a method to return a user's profile picture from MongoDB GridFS:

@RequestMapping(value = "user/avatar/{userId}", method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<InputStreamResource> downloadUserAvatarImage(@PathVariable Long userId) {
    GridFSDBFile gridFsFile = fileService.findUserAccountAvatarById(userId);

    return ResponseEntity.ok()
            .contentLength(gridFsFile.getLength())
            .contentType(MediaType.parseMediaType(gridFsFile.getContentType()))
            .body(new InputStreamResource(gridFsFile.getInputStream()));
}

The things to note:

• ResponseEntity with InputStreamResource as a return type

• ResponseEntity builder style creation

With this method you dont have to worry about autowiring in the HttpServletResponse, throwing an IOException or copying stream data around.

Try to close Eclipse IDE and reopen it and

The Android implementation of mipmaps in 4.3 is exactly the technique from 1983 explained in the Wikipedia article :)

Each bitmap image of the mipmap set is a downsized duplicate of the main texture, but at a certain reduced level of detail. Although the main texture would still be used when the view is sufficient to render it in full detail, the renderer will switch to a suitable mipmap image (...) when the texture is viewed from a distance or at a small size.

Although this is described as a technique for 3D graphics (as it mentions "viewing from a distance"), it applies just as well to 2D (translated as "drawn is a smaller space", i.e. "downscaled").

For a concrete Android example, imagine you have a View with a certain background drawable (in particular, a BitmapDrawable). You now use an animation to scale it to 0.15 of its original size. Normally, this would require downscaling the background bitmap for each frame. This "extreme" downscaling, however, may produce visual artifacts.

You can, however, provide a mipmap, which means that the image is already pre-rendered for a few specific scales (let's say 1.0, 0.5, and 0.25). Whenever the animation "crosses" the 0.5 threshold, instead of continuing to downscale the original, 1.0-sized image, it will switch to the 0.5 image and downscale it, which should provide a better result. And so forth as the animation continues.

This is a bit theoretical, since it's actually done by the renderer. According to the source of the Bitmap class, it's just a hint, and the renderer may or may not honor it.

/**
 * Set a hint for the renderer responsible for drawing this bitmap
 * indicating that it should attempt to use mipmaps when this bitmap
 * is drawn scaled down.
 *
 * If you know that you are going to draw this bitmap at less than
 * 50% of its original size, you may be able to obtain a higher
 * quality by turning this property on.
 * 
 * Note that if the renderer respects this hint it might have to
 * allocate extra memory to hold the mipmap levels for this bitmap.
 *
 * This property is only a suggestion that can be ignored by the
 * renderer. It is not guaranteed to have any effect.
 *
 * @param hasMipMap indicates whether the renderer should attempt
 *                  to use mipmaps
 *
 * @see #hasMipMap()
 */
public final void setHasMipMap(boolean hasMipMap) {
    nativeSetHasMipMap(mNativeBitmap, hasMipMap);
}

I'm not quite sure why this would be especially suitable for application icons, though. Although Android on tablets, as well as some launchers (e.g. GEL), request an icon "one density higher" to show it bigger, this is supposed to be done using the regular mechanism (i.e. drawable-xxxhdpi, &c).

In NixOS, there is rpmextract. It is a wrapper around rpm2cpio, exactly as @Alan Evangelista wanted. https://github.com/NixOS/nixpkgs/tree/master/pkgs/tools/archivers/rpmextract

You can change your UI culture to anything you want, but you should change the number separator like this:

CultureInfo info = new CultureInfo("fa-IR");
info.NumberFormat.NumberDecimalSeparator = ".";
Thread.CurrentThread.CurrentCulture = info;
Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;

With this, your strings converts like this: "12.49" instead of "12,49" or "12/49"

If you need the exact functionality of the back button in your custom button, why not just call yourActivity.onBackPressed() that way if you override the functionality of the backbutton your custom button will behave the same.

Models:

php artisan krlove:generate:model Videos --table-name=videos

Use unshift, which modifies the existing array by adding the arguments to the beginning:

TheArray.unshift(TheNewObject);

If you try to be aware of i18n the solution get even more complicated.

The problem is that in other languages the suffix may depend not only on the number itself, but also on the noun it counts. For example in Russian it would be "2-?? ????", but "2-?? ??????" (these mean "2nd day", but "2nd week"). This is not apply if we formatting only days, but in a bit more generic case you should be aware of complexity.

I think nice solution (I didn't have time to actually implement) would be to extend SimpleDateFormetter to apply Locale-aware MessageFormat before passing to the parent class. This way you would be able to support let say for March formats %M to get "3-rd", %MM to get "03-rd" and %MMM to get "third". From outside this class looks like regular SimpleDateFormatter, but supports more formats. Also if this pattern would be by mistake applied by regular SimpleDateFormetter the result would be incorrectly formatted, but still readable.

If you want to overwrite the element with key 0

function[0] = 42;

Otherwise:

function.insert(std::make_pair(0, 42));

Having effects on append won't work because the content the browser displays is updated as soon as the div is appended. So, to combine Mark B's and Steerpike's answers:

Style the div you're appending as hidden before you actually append it. You can do it with inline or external CSS script, or just create the div as

<div id="new_div" style="display: none;"> ... </div>

Then you can chain effects to your append (demo):

$('#new_div').appendTo('#original_div').show('slow');

Or (demo):

var $new = $('#new_div');
$('#original_div').append($new);
$new.show('slow');

Three ways to pass model data to partial view (there may be more)

This is view page

Method One Populate at view

@{    
    PartialViewTestSOl.Models.CountryModel ctry1 = new PartialViewTestSOl.Models.CountryModel();
    ctry1.CountryName="India";
    ctry1.ID=1;    

    PartialViewTestSOl.Models.CountryModel ctry2 = new PartialViewTestSOl.Models.CountryModel();
    ctry2.CountryName="Africa";
    ctry2.ID=2;

    List<PartialViewTestSOl.Models.CountryModel> CountryList = new List<PartialViewTestSOl.Models.CountryModel>();
    CountryList.Add(ctry1);
    CountryList.Add(ctry2);    

}

@{
    Html.RenderPartial("~/Views/PartialViewTest.cshtml",CountryList );
}

Method Two Pass Through ViewBag

@{
    var country = (List<PartialViewTestSOl.Models.CountryModel>)ViewBag.CountryList;
    Html.RenderPartial("~/Views/PartialViewTest.cshtml",country );
}

Method Three pass through model

@{
    Html.RenderPartial("~/Views/PartialViewTest.cshtml",Model.country );
}

The beauty of String(format:) is that you can save a formatting string and then reuse it later in dozen of places. It also can be localized in this single place. Where as in case of the interpolation approach you must write it again and again.

Here ya go:

viewNoteDateMonth.text  = [[displayDate objectAtIndex:2] uppercaseString];

Btw:
"april" is lowercase ? [NSString lowercaseString]
"APRIL" is UPPERCASE ? [NSString uppercaseString]
"April May" is Capitalized/Word Caps ? [NSString capitalizedString]
"April may" is Sentence caps ? (method missing; see workaround below)

Hence what you want is called "uppercase", not "capitalized". ;)

As for "Sentence Caps" one has to keep in mind that usually "Sentence" means "entire string". If you wish for real sentences use the second method, below, otherwise the first:

@interface NSString ()

- (NSString *)sentenceCapitalizedString; // sentence == entire string
- (NSString *)realSentenceCapitalizedString; // sentence == real sentences

@end

@implementation NSString

- (NSString *)sentenceCapitalizedString {
    if (![self length]) {
        return [NSString string];
    }
    NSString *uppercase = [[self substringToIndex:1] uppercaseString];
    NSString *lowercase = [[self substringFromIndex:1] lowercaseString];
    return [uppercase stringByAppendingString:lowercase];
}

- (NSString *)realSentenceCapitalizedString {
    __block NSMutableString *mutableSelf = [NSMutableString stringWithString:self];
    [self enumerateSubstringsInRange:NSMakeRange(0, [self length])
                             options:NSStringEnumerationBySentences
                          usingBlock:^(NSString *sentence, NSRange sentenceRange, NSRange enclosingRange, BOOL *stop) {
        [mutableSelf replaceCharactersInRange:sentenceRange withString:[sentence sentenceCapitalizedString]];
    }];
    return [NSString stringWithString:mutableSelf]; // or just return mutableSelf.
}

@end

All of the previous answers are talking about git branch -m. Of course, it's easy to operate, but for me, it may be a little hard to remember another Git command. So I tried to get the work done by the command I was familiar with. Yeah, you may guessed it.

I use git branch -b <new_branch_name>. And if you don't want to save the old branch now you can execute git branch -D <old_branch_name> to remove it.

I know it may be a little tedious, but it's easier to understand and remember. I hope it‘s helpful for you.

I think this is better, following the good practices of passing parameters to the query:

BookingDates::whereRaw('email = ? or name like ?', [$request->email,"%{$request->name}%"])->get();

You can see it in the documentation, Laravel 5.5.

You can also use the Laravel scout and make it easier with search. Here is the documentation.

It is best practice to go asynchronous if you can do several things in parallel (no inter-dependencies). If you need it to complete to continue loading the next thing you could use synchronous, but note that this option is deprecated to avoid abuse of sync:

jQuery.ajax() method's async option deprecated, what now?

use this command on your script file after copying it to Linux/Unix

perl -pi -e 's/\r//' scriptfilename

{
     public Exception(string message)
     {
         [...]
     }
}

class MyExceptionClass : Exception
{
     public MyExceptionClass(string message, string extraInfo)
     : base(message)
     {
         [...]
     }
}

this simple code work 100% all you need is changing 'lat','long' for address to show

<iframe src="http://maps.google.com/maps?q=25.3076008,51.4803216&z=16&output=embed" height="450" width="600"></iframe>

Any time you do a remove() or a removeAll(), you should call

  validate();
  repaint();

after you have completed add()'ing the new components.

Calling validate() or revalidate() is mandatory when you do a remove() - see the relevant javadocs.

My own testing indicates that repaint() is also necessary. I'm not sure exactly why.

I just faced the same issue with Fedora26 where many tools such as dnf were broken due to bad magic number for six. For an unknown reason i've got a file /usr/bin/six.pyc, with the unexpected magic number. Deleting this file fix the problem

Contrary to what pointy says, the blur() method does exist and is a part of the w3c standard. The following exaple will work in every modern browser (including IE):

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
    <head>
        <title>Javascript test</title>
        <script type="text/javascript" language="javascript">
            window.onload = function()
            {
                var field = document.getElementById("field");
                var link = document.getElementById("link");
                var output = document.getElementById("output");

                field.onfocus = function() { output.innerHTML += "<br/>field.onfocus()"; };
                field.onblur = function() { output.innerHTML += "<br/>field.onblur()"; };
                link.onmouseover = function() { field.blur(); };
            };
        </script>
    </head>
    <body>
        <form name="MyForm">
            <input type="text" name="field" id="field" />
            <a href="javascript:void(0);" id="link">Blur field on hover</a>
            <div id="output"></div>
        </form>
    </body>
</html>

Note that I used link.onmouseover instead of link.onclick, because otherwise the click itself would have removed the focus.

function tar.create() {
        local folder="${1}"
        
        local tar="$(basename "${folder}")".tar.gz
        
        cd "${folder}" && tar -zcvf "../${tar}" .; cd - &> /dev/null
}

Example:

tar.create /path/to/folder

You are welcome.

Did you mean this?

$('#i_file').change( function(event) {
var tmppath = URL.createObjectURL(event.target.files[0]);
    $("img").fadeIn("fast").attr('src',tmppath);       
});

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

Suppose we have a file as Message.cpp or a .c file

Steps 1: Preprocessing (Argument -E )

g++ -E .\Message.cpp > P1

P1 file generated has expanded macros and header file contents and comments are stripped off.

Step 2: Translate Preprocessed file to assembly (Argument -S). This task is done by compiler

g++ -S .\Message.cpp

An assembler (ASM) is generated (Message.s). It has all the assembly code.

Step 3: Translate assembly code to Object code. Note: Message.s was generated in Step2. g++ -c .\Message.s

An Object file with the name Message.o is generated. It is the binary form.

Step 4: Linking the object file. This task is done by linker

g++ .\Message.o -o MessageApp

An exe file MessageApp.exe is generated here.

#include <iostream>
using namespace std;

 //This a sample program
  int main()
{
cout << "Hello" << endl;
 cout << PQR(P,K) ;
getchar();
return 0;
}

In HTML5 there is no scrolling attribute because "its function is better handled by CSS" see http://www.w3.org/TR/html5-diff/ for other changes. Well and the CSS solution:

CSS solution:

HTML4's scrolling="no" is kind of an alias of the CSS's overflow: hidden, to do so it is important to set size attributes width/height:

iframe.noScrolling{
  width: 250px; /*or any other size*/
  height: 300px; /*or any other size*/
  overflow: hidden;
}

Add this class to your iframe and you're done:

<iframe src="http://www.example.com/" class="noScrolling"></iframe>

! IMPORTANT NOTE ! : overflow: hidden for <iframe> is not fully supported by all modern browsers yet(even chrome doesn't support it yet) so for now (2013) it's still better to use Transitional version and use scrolling="no" and overflow:hidden at the same time :)

UPDATE 2020: the above is still true, oveflow for iframes is still not supported by all majors

I periodically search for a satisfactory answer to this, but no luck so far. I use soapUI + requests + manual labour.

I gave up and used Java the last time I needed to do this, and simply gave up a few times the last time I wanted to do this, but it wasn't essential.

Having successfully used the requests library last year with Project Place's RESTful API, it occurred to me that maybe I could just hand-roll the SOAP requests I want to send in a similar way.

Turns out that's not too difficult, but it is time consuming and prone to error, especially if fields are inconsistently named (the one I'm currently working on today has 'jobId', JobId' and 'JobID'. I use soapUI to load the WSDL to make it easier to extract endpoints etc and perform some manual testing. So far I've been lucky not to have been affected by changes to any WSDL that I'm using.

You can use LINQ:

String.Concat(str.OrderBy(c => c))

If you want to remove duplicates, add .Distinct().

Yeah first method will work on any element called from elsewhere since it will always take the target element irrespective of id.

I have seen in unidirectional @ManytoOne, delete don't work as expected. When parent is deleted, ideally child should also be deleted, but only parent is deleted and child is NOT deleted and is left as orphan

Technology used are Spring Boot/Spring Data JPA/Hibernate

Sprint Boot : 2.1.2.RELEASE

Spring Data JPA/Hibernate is used to delete row .eg

parentRepository.delete(parent)

ParentRepository extends standard CRUD repository as shown below ParentRepository extends CrudRepository<T, ID>

Following are my entity class

@Entity(name = “child”)
public class Child  {

    @Id
    @GeneratedValue
    private long id;

    @ManyToOne( fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = “parent_id", nullable = false)
    @OnDelete(action = OnDeleteAction.CASCADE)
    private Parent parent;
}

@Entity(name = “parent”)
public class Parent {

    @Id
    @GeneratedValue
    private long id;

    @Column(nullable = false, length = 50)
    private String firstName;


}

This should get you started:

Old question but worth adding an answer if using .NET Core 3.0 or later. JSON serialization/deserialization is built into the framework (System.Text.Json), so you don't have to use third party libraries any more. Here's an example based off the top answer given by @Icarus

using System;
using System.Collections.Generic;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var json = "[{\"Name\":\"John Smith\", \"Age\":35}, {\"Name\":\"Pablo Perez\", \"Age\":34}]";

            // use the built in Json deserializer to convert the string to a list of Person objects
            var people = System.Text.Json.JsonSerializer.Deserialize<List<Person>>(json);

            foreach (var person in people)
            {
                Console.WriteLine(person.Name + " is " + person.Age + " years old.");
            }
        }

        public class Person
        {
            public int Age { get; set; }
            public string Name { get; set; }
        }
    }
}

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

There is something wrong in your setDelimiter() function. You don't want to double quote the delimiters, do you?

public void setDelimiter(String delimiter) {
    char[] c = delimiter.toCharArray();
    this.delimiter = "\\" + c[0] + "\\" + c[1];
    System.out.println("Delimiter string is: " + this.delimiter);
}

However, as other users have said, it's better to use the Pattern.quote() method to escape your delimiter if your requirements permit.

To plot text on a ggplot you use the geom_text. But I find it helpful to summarise the data first using ddply

dfl <- ddply(df, .(x), summarize, y=length(x))
str(dfl)

Since the data is pre-summarized, you need to remember to change add the stat="identity" parameter to geom_bar:

ggplot(dfl, aes(x, y=y, fill=x)) + geom_bar(stat="identity") +
    geom_text(aes(label=y), vjust=0) +
    opts(axis.text.x=theme_blank(),
        axis.ticks=theme_blank(),
        axis.title.x=theme_blank(),
        legend.title=theme_blank(),
        axis.title.y=theme_blank()
)

Tried list[:][0] to show all first member of each list inside list is not working. Result is unknowingly will same as list[0][:]

So i use list comprehension like this:

[i[0] for i in list] which return first element value for each list inside list.

Man, try the min-height.

.div1 {
    float: left;
    height: 100%;
    min-height: 100%;
    width: 25%;
}
.div2 {
    float: left;
    height: 100%;
    min-height: 100%;
    width: 75%;
}

I had this problem for several days, it turns out if I created the db inside phpMyAdmin it wouldn't appear to Laravel, so, I created the db through MySqlWorkbench, and it worked :)

In case of multiple inheritance level, this function can be used as a super() method in other languages. Here is a demo fiddle, with some tests, you can use it like this, inside your method use : call_base(this, 'method_name', arguments);

It make use of quite recent ES functions, an compatibility with older browsers is not guarantee. Tested in IE11, FF29, CH35.

/**
 * Call super method of the given object and method.
 * This function create a temporary variable called "_call_base_reference",
 * to inspect whole inheritance linage. It will be deleted at the end of inspection.
 *
 * Usage : Inside your method use call_base(this, 'method_name', arguments);
 *
 * @param {object} object The owner object of the method and inheritance linage
 * @param {string} method The name of the super method to find.
 * @param {array} args The calls arguments, basically use the "arguments" special variable.
 * @returns {*} The data returned from the super method.
 */
function call_base(object, method, args) {
    // We get base object, first time it will be passed object,
    // but in case of multiple inheritance, it will be instance of parent objects.
    var base = object.hasOwnProperty('_call_base_reference') ? object._call_base_reference : object,
    // We get matching method, from current object,
    // this is a reference to define super method.
            object_current_method = base[method],
    // Temp object wo receive method definition.
            descriptor = null,
    // We define super function after founding current position.
            is_super = false,
    // Contain output data.
            output = null;
    while (base !== undefined) {
        // Get method info
        descriptor = Object.getOwnPropertyDescriptor(base, method);
        if (descriptor !== undefined) {
            // We search for current object method to define inherited part of chain.
            if (descriptor.value === object_current_method) {
                // Further loops will be considered as inherited function.
                is_super = true;
            }
            // We already have found current object method.
            else if (is_super === true) {
                // We need to pass original object to apply() as first argument,
                // this allow to keep original instance definition along all method
                // inheritance. But we also need to save reference to "base" who
                // contain parent class, it will be used into this function startup
                // to begin at the right chain position.
                object._call_base_reference = base;
                // Apply super method.
                output = descriptor.value.apply(object, args);
                // Property have been used into super function if another
                // call_base() is launched. Reference is not useful anymore.
                delete object._call_base_reference;
                // Job is done.
                return output;
            }
        }
        // Iterate to the next parent inherited.
        base = Object.getPrototypeOf(base);
    }
}

As Ollie C mentioned, there is an active bug for the support library using returned values to onActivityResult when you are using nested fragments. I just hit it :-(.

See Fragment.onActivityResult not called when requestCode != 0.

I had the same error and it turned out to be a circular dependency between a module or class loaded by the settings and the settings module itself. In my case it was a middleware class which was named in the settings which itself tried to load the settings.

I think that still there isnt any answer here with easy and readable working example. Use MutationObserver interface to detect DOM changes, like this:

var observer = new MutationObserver(function(mutations) {_x000D_
    if ($("p").length) {_x000D_
        console.log("Exist, lets do something");_x000D_
        observer.disconnect(); _x000D_
        //We can disconnect observer once the element exist if we dont want observe more changes in the DOM_x000D_
    }_x000D_
});_x000D_
_x000D_
// Start observing_x000D_
observer.observe(document.body, { //document.body is node target to observe_x000D_
    childList: true, //This is a must have for the observer with subtree_x000D_
    subtree: true //Set to true if changes must also be observed in descendants._x000D_
});_x000D_
            _x000D_
$(document).ready(function() {_x000D_
    $("button").on("click", function() {_x000D_
        $("p").remove();_x000D_
        setTimeout(function() {_x000D_
            $("#newContent").append("<p>New element</p>");_x000D_
        }, 2000);_x000D_
    });_x000D_
});

Note: Spanish Mozilla docs about MutationObserver are more detailed if you want more information.

You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.

Here is how to create a DataFrame where each series is a row.

For a single Series (resulting in a single-row DataFrame):

series = pd.Series([1,2], index=['a','b'])
df = pd.DataFrame([series])

For multiple series with identical indices:

cols = ['a','b']
list_of_series = [pd.Series([1,2],index=cols), pd.Series([3,4],index=cols)]
df = pd.DataFrame(list_of_series, columns=cols)

For multiple series with possibly different indices:

list_of_series = [pd.Series([1,2],index=['a','b']), pd.Series([3,4],index=['a','c'])]
df = pd.concat(list_of_series, axis=1).transpose()

To create a DataFrame where each series is a column, see the answers by others. Alternatively, one can create a DataFrame where each series is a row, as above, and then use df.transpose(). However, the latter approach is inefficient if the columns have different data types.

The return statement only makes sense inside functions:

def foo():
    while True:
        return False

You only need to force cscript instead wscript. I always use this template. The function ForceConsole() will execute your vbs into cscript, also you have nice alias to print and scan text.

 Set oWSH = CreateObject("WScript.Shell")
 vbsInterpreter = "cscript.exe"

 Call ForceConsole()

 Function printf(txt)
    WScript.StdOut.WriteLine txt
 End Function

 Function printl(txt)
    WScript.StdOut.Write txt
 End Function

 Function scanf()
    scanf = LCase(WScript.StdIn.ReadLine)
 End Function

 Function wait(n)
    WScript.Sleep Int(n * 1000)
 End Function

 Function ForceConsole()
    If InStr(LCase(WScript.FullName), vbsInterpreter) = 0 Then
        oWSH.Run vbsInterpreter & " //NoLogo " & Chr(34) & WScript.ScriptFullName & Chr(34)
        WScript.Quit
    End If
 End Function

 Function cls()
    For i = 1 To 50
        printf ""
    Next
 End Function

 printf " _____ _ _           _____         _    _____         _     _   "
 printf "|  _  |_| |_ ___ ___|     |_ _ _ _| |  |   __|___ ___|_|___| |_ "

The user-agent should be specified as a field in the header.

Here is a list of HTTP header fields, and you'd probably be interested in request-specific fields, which includes User-Agent.

If you're using requests v2.13 and newer

The simplest way to do what you want is to create a dictionary and specify your headers directly, like so:

import requests

url = 'SOME URL'

headers = {
    'User-Agent': 'My User Agent 1.0',
    'From': '[email protected]'  # This is another valid field
}

response = requests.get(url, headers=headers)

If you're using requests v2.12.x and older

Older versions of requests clobbered default headers, so you'd want to do the following to preserve default headers and then add your own to them.

import requests

url = 'SOME URL'

# Get a copy of the default headers that requests would use
headers = requests.utils.default_headers()

# Update the headers with your custom ones
# You don't have to worry about case-sensitivity with
# the dictionary keys, because default_headers uses a custom
# CaseInsensitiveDict implementation within requests' source code.
headers.update(
    {
        'User-Agent': 'My User Agent 1.0',
    }
)

response = requests.get(url, headers=headers)

You can use qTip for this; However you'd have to code a little for launching it on mouseover event; And in case you want a default watermark on your text fields, you'd have to use the watermark plugin...

I realized that this leads to lot of repetitive code; So I wrote a plugin on top of qTip that makes it really easy to attach informational popup to form fields. You can check it out here: https://bitbucket.org/gautamtandon/jquery.attachinfo

Hope this helps.

In the hopes it might narrow things down/help someone, I did an investigatory approach. For me, I initially moved the folder at C:\Users\{user}\AppData\Local\Microsoft\VisualStudio to My Documents and allowed Visual Studio to re-create it by re-launching it. This removed the errors. So I moved everything back, one-by-one, and restarted Visual Studio each time until I discovered the culprits. These folders were fine to move back in:

• 1033 (overwrote the auto-generated copy with old)
• Designer (was in my old copy, not initially re-created when I re-launched VS, copied it back in)
• Extensions (overwrote the auto-generated copy with old)
• ImageLibrary (overwrote the auto-generated copy with old)
• Notifications (overwrote the auto-generated copy with old)
• STemplate (was in my old copy, not initially re-created when I re-launched VS, copied it back in)
• VTC (was in my old copy, not initially re-created when I re-launched VS, copied it back in)

These files were fine to move back in/overwrite the auto-generated ones:

• ApplicationPrivateSettings (was in my old copy, not initially re-created when I re-launched VS)
• ApplicationPrivateSettings.lock (overwrote the auto-generated copy with old)
• vspdmc.lock (overwrote the auto-generated copy with old)

These files were fine to move back in. Each was in my old copy, and not initially re-created when I re-launched VS:

• .NETFramework,Version=v4.0,Set=Framework,Hash=C958D412.dat
• .NETFramework,Version=v4.0,Set=RecentAssemblies,Hash=0.dat
• .NETFramework,Version=v4.5,Set=Extensions,Hash=75EAE334.dat
• .NETFramework,Version=v4.5,Set=Extensions,Hash=497525A2.dat
• .NETFramework,Version=v4.5,Set=Framework,Hash=5AE9A175.dat
• .NETFramework,Version=v4.5.2,Set=Extensions,Hash=24CEEB0D.dat
• .NETFramework,Version=v4.5.2,Set=Extensions,Hash=72AE305.dat
• .NETFramework,Version=v4.5.2,Set=Extensions,Hash=ADF899D7.dat
• .NETFramework,Version=v4.5.2,Set=Framework,Hash=D8E943A2.dat

These caused problems - delete these files and re-launch VS to allow it to re-create them:

• ComponentModelCache - When I overwrote this folder's contents with my old ones (4 files: MS.VS.Default.cache, .catalogs, .err, .external), this gave me all of the errors I had gotten before about not being able to load packages when loading my project, and the "object reference not set to an instance of an object" error when trying to close VS.
• devenv.exe.config - same as ComponentModelCache
• .NETFramework,Version=v4.0,Set=Extensions,Hash=6D09DECC.dat - causes error output from the JavaScript Language Service, complaining of missing js files
• .NETFramework,Version=v4.0,Set=Extensions,Hash=9951BC03.dat - causes error output from the JavaScript Language Service, complaining of missing js files
• .NETFramework,Version=v4.5.2,Set=RecentAssemblies,Hash=0.dat - causes error output from the JavaScript Language Service, complaining of missing js files

These are the errors from those last .NETFramework files (which I do not get if I do not add them back in):

I might just need to re-install/repair the JavaScript Language Service plug-in, so it might be un-related. But definitely devenv.exe.config and ComponentModelCache need to go to correct the "object reference not set to an instance of an object" error.

This one can also be used with less effort I believe (but I am in MVC 5)

@Html.Description(model => model.Story, 20, 50, new { })

The solution is that you should uncheck (deactivate) option "Run only if user is logged on".

After that change, it starts to work on my machine.

If you declare an empty object literal and then assign values later on, then you can consider those values optional (may or may not be there), so just type them as optional with a question mark:

type User = {
    Username?: string;
    Email?: string;
}

There are subtle and not-so-subtle differences between generic and non-generic collections. They merely use different underlying data structures. For example, Hashtable guarantees one-writer-many-readers without sync. Dictionary does not.

Interfaces and abstracted classes seem very similar, however, there are important differences between them.

Abstraction is based on a good "is-a" relationship. Meaning that you would say that a car is a Honda, and a Honda is a car. Using abstraction on a class means you can also have abstract methods. This would require any subclass extended from it to obtain the abstract methods and override them. Using the example below, we can create an abstract howToStart(); method that will require each class to implement it.

Through abstraction, we can provide similarities between code so we would still have a base class. Using an example of the Car class idea we could create:

public abstract class Car{
    private String make;
    private String model

    protected Car() { }  // Default constructor

    protect Car(String make, String model){
        //Assign values to 
    }

    public abstract void howToStart();
}

Then with the Honda class we would have:

public class Honda extends implements Engine {

    public Honda() { }  // Default constructor

    public Honda(String make, String model){
        //Assign values
    }

    @Override
    public static void howToStart(){
        // Code on how to start
    }

}

Interfaces are based on the "has-a" relationship. This would mean you could say a car has-a engine, but an engine is not a car. In the above example, Honda has implements Engine.

For the engine interface we could create:

public interface Engine {
    public void startup();
}

The interface will provide a many-to-one instance. So we could apply the Engine interface to any type of car. We can also extend it to other object. Like if we were to make a boat class, and have sub classes of boat types, we could extend Engine and have the sub classes of boat require the startup(); method. Interfaces are good for creating framework to various classes that have some similarities. We can also implement multiple instances in one class, such as:

public class Honda extends implements Engine, Transmission, List<Parts>

Hopefully this helps.

just add .col-xs-12 to your responsive image. It's should work.

If you just want to remove the first two characters and the last two, then you can use negative indexes on the string:

s = "((String1))"
s = s[2...-2]
p s # => "String1"

If you want to remove all parentheses from the string you can use the delete method on the string class:

s = "((String1))"
s.delete! '()'
p s #  => "String1"

This worked for me

EditText   etname = (EditText) findViewById(R.id.etname);
 if(etname.length() == 0){
                    etname.setError("Required field");
                }else{
                    Toast.makeText(getApplicationContext(),"Saved",Toast.LENGTH_LONG).show();
                }

or Use this for strings

String DEP_DATE;
if (DEP_DATE.equals("") || DEP_DATE.length() == 0 || DEP_DATE.isEmpty() || DEP_DATE == null){
}

With your current requirement this would work :

    def start_html():
        return '<html>'

    def end_html():
        return '</html>'

    def print_html(text):
        text = str(text)
        text = text.replace('\n', '<br>')
        return '<p>' + str(text) + '</p>'
if __name__ == '__main__':
        webpage_data =  start_html()
        webpage_data += print_html("Hi Welcome to Python test page\n")
        webpage_data += fd.write(print_html("Now it will show a calculation"))
        webpage_data += print_html("30+2=")
        webpage_data += print_html(30+2)
        webpage_data += end_html()
        with open('index.html', 'w') as fd: fd.write(webpage_data)

open the index.html and you will see what you want

It looks you have just as good a schema to work with as me... Here is how to do it correctly:

In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists 
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 

        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';


        -- Check if they keys are unique (it is very possible they might not be) 
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

            -- Adding foreign key
            IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms') 
                ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID); 
        END -- End uniqueness check
        ELSE
            PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...' 
    END -- End NULL check
    ELSE
        PRINT 'FSCK, need to figure out how to update NULL value(s)...' 
END

from bs4 import BeautifulSoup

soup= BeautifulSoup(html.text,'lxml')
results = soup.findAll("td", {"valign" : re.compile(r".*")})

as per Steve Lorimer better to pass True instead of regex

results = soup.findAll("td", {"valign" : True})

Add the following to your ~/.gitconfig file

[alias]
  cat = "!git show \"$1:$2\" #"

And then try this

git cat BRANCHNAME FILEPATH

Personally I prefer separate parameters without a colon. Why? This choice mirrors the parameters of the checkout command, which I tend to use rather frequently and I find it thus much easier to remember than the bizarro colon-separated parameter of the show command.

https://angular.io/docs/ts/latest/guide/router.html

Add the base element just after the <head> tag. If the app folder is the application root, as it is for our application, set the href value exactly as shown here.

The <base href="/"> tells the Angular router what is the static part of the URL. The router then only modifies the remaining part of the URL.

<head>
  <base href="/">
  ...
</head>

Alternatively add

>= Angular2 RC.6

import {APP_BASE_HREF} from '@angular/common';

@NgModule({
  declarations: [AppComponent],
  imports: [routing /* or RouterModule */], 
  providers: [{provide: APP_BASE_HREF, useValue : '/' }]
]); 

in your bootstrap.

In older versions the imports had to be like

< Angular2 RC.6

import {APP_BASE_HREF} from '@angular/common';
bootstrap(AppComponent, [
  ROUTER_PROVIDERS, 
  {provide: APP_BASE_HREF, useValue : '/' });
]); 

< RC.0

import {provide} from 'angular2/core';
bootstrap(AppComponent, [
  ROUTER_PROVIDERS, 
  provide(APP_BASE_HREF, {useValue : '/' });
]); 

< beta.17

import {APP_BASE_HREF} from 'angular2/router';

>= beta.17

import {APP_BASE_HREF} from 'angular2/platform/common';

A simple solution is to assign color for each class. This way, we can control how each color is for each class. For example:

arr1 = [1, 2, 3, 4, 5]
arr2 = [2, 3, 3, 4, 4]
labl = [0, 1, 1, 0, 0]
color= ['red' if l == 0 else 'green' for l in labl]
plt.scatter(arr1, arr2, color=color)

It seems that the struct datatype is commonly used in SOAP:

var_dump($client->__getTypes());

array(52) {
  [0] =>
  string(43) "struct Bank {\n string Code;\n string Name;\n}"
}

This is not a native PHP datatype!

It seems that the properties of the struct type referred to in SOAP can be accessed as a simple PHP stdClass object:

$some_struct = $client->SomeMethod();
echo 'Name: ' . $some_struct->Name;

How to reproduce this error:

SyntaxError: missing ) after argument list

This code produces the error:

<html>
<body>
<script type="text/javascript" src="jquery-2.1.0.min.js"></script>
<script type="text/javascript">
  $(document).ready(function(){

  }
</script>
</body>
</html>

If you run this and look at the error output in firebug, you get this error. The empty function passed into 'ready' is not closed. Fix it like this:

<html>
<body>
<script type="text/javascript" src="jquery-2.1.0.min.js"></script>
<script type="text/javascript">
  $(document).ready(function(){

  });      //<-- notice the right parenthesis and semicolon
</script>
</body>
</html>

And then the Javascript is interpreted correctly.

Read about Storage Engines.

MyISAM:

The MyISAM storage engine in MySQL.

• Simpler to design and create, thus better for beginners. No worries about the foreign relationships between tables.
• Faster than InnoDB on the whole as a result of the simpler structure thus much less costs of server resources. -- Mostly no longer true.
• Full-text indexing. -- InnoDB has it now
• Especially good for read-intensive (select) tables. -- Mostly no longer true.
• Disk footprint is 2x-3x less than InnoDB's. -- As of Version 5.7, this is perhaps the only real advantage of MyISAM.

InnoDB:

The InnoDB storage engine in MySQL.

• Support for transactions (giving you support for the ACID property).
• Row-level locking. Having a more fine grained locking-mechanism gives you higher concurrency compared to, for instance, MyISAM.
• Foreign key constraints. Allowing you to let the database ensure the integrity of the state of the database, and the relationships between tables.
• InnoDB is more resistant to table corruption than MyISAM.
• Support for large buffer pool for both data and indexes. MyISAM key buffer is only for indexes.
• MyISAM is stagnant; all future enhancements will be in InnoDB. This was made abundantly clear with the roll out of Version 8.0.

MyISAM Limitations:

• No foreign keys and cascading deletes/updates
• No transactional integrity (ACID compliance)
• No rollback abilities
• 4,284,867,296 row limit (2^32) -- This is old default. The configurable limit (for many versions) has been 2**56 bytes.
• Maximum of 64 indexes per table

InnoDB Limitations:

• No full text indexing (Below-5.6 mysql version)
• Cannot be compressed for fast, read-only (5.5.14 introduced ROW_FORMAT=COMPRESSED)
• You cannot repair an InnoDB table

Use this code it works perfectly for odd or even list sizes. Hope it help somebody .

 int listSize = listOfArtist.size();
 int mid = 0;
 if (listSize % 2 == 0) {
    mid = listSize / 2;
    Log.e("Parting", "You entered an even number. mid " + mid
                    + " size is " + listSize);
 } else {
    mid = (listSize + 1) / 2;
    Log.e("Parting", "You entered an odd number. mid " + mid
                    + " size is " + listSize);
 }
 //sublist returns List convert it into arraylist * very important
 leftArray = new ArrayList<ArtistModel>(listOfArtist.subList(0, mid));
 rightArray = new ArrayList<ArtistModel>(listOfArtist.subList(mid,
                listSize));

You have a scope problem indeed, because statement is a local method variable defined here:

protected void createContents() {
    ...
    Statement statement = null; // local variable
    ...
     btnInsert.addMouseListener(new MouseAdapter() { // anonymous inner class
        @Override
        public void mouseDown(MouseEvent e) {
            ...
            try {
                statement.executeUpdate(query); // local variable out of scope here
            } catch (SQLException e1) {
                e1.printStackTrace();
            }
            ...
    });
}

When you try to access this variable inside mouseDown() method you are trying to access a local variable from within an anonymous inner class and the scope is not enough. So it definitely must be final (which given your code is not possible) or declared as a class member so the inner class can access this statement variable.

Sources:

• Anonymous Classes
• How are Anonymous (inner) classes used in Java?

How to solve it?

You could...

Make statement a class member instead of a local variable:

public class A1 { // Note Java Code Convention, also class name should be meaningful   
    private Statement statement;
    ...
}

You could...

Define another final variable and use this one instead, as suggested by @HotLicks:

protected void createContents() {
    ...
    Statement statement = null;
    try {
        statement = connect.createStatement();
        final Statement innerStatement = statement;
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    ...
}

But you should...

Reconsider your approach. If statement variable won't be used until btnInsert button is pressed then it doesn't make sense to create a connection before this actually happens. You could use all local variables like this:

btnInsert.addMouseListener(new MouseAdapter() {
   @Override
   public void mouseDown(MouseEvent e) {
       try {
           Class.forName("com.mysql.jdbc.Driver");
           try (Connection connect = DriverManager.getConnection(...);
                Statement statement = connect.createStatement()) {

                // execute the statement here

           } catch (SQLException ex) {
               ex.printStackTrace();
           }

       } catch (ClassNotFoundException ex) {
           e.printStackTrace();
       }
});

First check if the table/column(id/name) combination exists in dbo.syscolumns (an internal SQL Server table that contains field definitions), and if not issue the appropriate ALTER TABLE query to add it. For example:

IF NOT EXISTS ( SELECT  *
            FROM    syscolumns
            WHERE   id = OBJECT_ID('Client')
                    AND name = 'Name' ) 
ALTER TABLE Client
ADD Name VARCHAR(64) NULL

If you are trying to find a View from your Fragment then try doing it like this:

int w = ((EditText)getActivity().findViewById(R.id.editText1)).getLayoutParams().width;

Answer by @Ben proved to be useful for me. But I needed to check the product version as it was the main increment happening in my software and followed semantic versioning.

myFileVersionInfo.ProductVersion

This method met my expectations

Update: Instead of explicitly mentioning dll path in program (as needed in production version), we can get product version using Assembly.

Assembly assembly = Assembly.GetExecutingAssembly();
FileVersionInfo fileVersionInfo =FileVersionInfo.GetVersionInfo(assembly.Location); 
string ProdVersion= fileVersionInfo.ProductVersion;

You can run your script via cmd and be in script-directory:

cmd /k cd /d $(CURRENT_DIRECTORY) && python $(FULL_CURRENT_PATH)

The only editor I know of that has syntax highlighting and a fallback to a textarea is Mozilla Bespin. Google around for embedding Bespin to see how to embed the editor. The only site I know of that uses this right now is the very alpha Mozilla Jetpack Gallery (in the submit a Jetpack page) and you may want to see how they include it.

There's also a blog post on embedding and reusing the Bespin editor that may help you.

Well for anyone still having the problem and I really feel very dumb after realizing this, but I passed in the url of /items the default one while adding API. But I kept calling the endpoint with /api. Special thanks to Carlos Alberto Schneider, as I realized my problem after reading your post.

Why do you use Restrictions.like(...)?

You should use Restrictions.eq(...).

Note you can also use .le, .lt, .ge, .gt on date objects as comparison operators. LIKE operator is not appropriate for this case since LIKE is useful when you want to match results according to partial content of a column. Please see http://www.sql-tutorial.net/SQL-LIKE.asp for the reference.

For example if you have a name column with some people's full name, you can do where name like 'robert %' so that you will return all entries with name starting with 'robert ' (% can replace any character).

In your case you know the full content of the date you're trying to match so you shouldn't use LIKE but equality. I guess Hibernate doesn't give you any exception in this case, but anyway you will probably have the same problem with the Restrictions.eq(...).

Your date object you got with the code:

SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-YYYY");
String myDate = "17-04-2011";
Date date = formatter.parse(myDate);

This date object is equals to the 17-04-2011 at 0h, 0 minutes, 0 seconds and 0 nanoseconds.

This means that your entries in database must have exactly that date. What i mean is that if your database entry has a date "17-April-2011 19:20:23.707000000", then it won't be retrieved because you just ask for that date: "17-April-2011 00:00:00.0000000000".

If you want to retrieve all entries of your database from a given day, you will have to use the following code:

    SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-YYYY");
    String myDate = "17-04-2011";
    // Create date 17-04-2011 - 00h00
    Date minDate = formatter.parse(myDate);
    // Create date 18-04-2011 - 00h00 
    // -> We take the 1st date and add it 1 day in millisecond thanks to a useful and not so known class
    Date maxDate = new Date(minDate.getTime() + TimeUnit.DAYS.toMillis(1));
    Conjunction and = Restrictions.conjunction();
    // The order date must be >= 17-04-2011 - 00h00
    and.add( Restrictions.ge("orderDate", minDate) );
    // And the order date must be < 18-04-2011 - 00h00
    and.add( Restrictions.lt("orderDate", maxDate) ); 

It's just what it says:

inputFile = open((x), encoding = "utf8", "r")

You have specified encoding as a keyword argument, but "r" as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:

inputFile = open((x), "r", encoding = "utf8")

I would use the #{} constructor, as stated by the other answers. I also want to point out there is a real subtlety here to watch out for here:

2.0.0p247 :001 > first_name = 'jim'
 => "jim" 
2.0.0p247 :002 > second_name = 'bob'
 => "bob" 
2.0.0p247 :003 > full_name = '#{first_name} #{second_name}'
 => "\#{first_name} \#{second_name}" # not what we expected, expected "jim bob"
2.0.0p247 :004 > full_name = "#{first_name} #{second_name}"
 => "jim bob" #correct, what we expected

While strings can be created with single quotes (as demonstrated by the first_name and last_name variables, the #{} constructor can only be used in strings with double quotes.

Use memory.limit(). You can increase the default using this command, memory.limit(size=2500), where the size is in MB. You need to be using 64-bit in order to take real advantage of this.

One other suggestion is to use memory efficient objects wherever possible: for instance, use a matrix instead of a data.frame.

I am also facing the same problem in Safari Browser

var date = new Date("2011-02-07");
console.log(date) // IE you get ‘NaN’ returned and in Safari you get ‘Invalid Date’

Here the solution:

var d = new Date(2011, 01, 07); // yyyy, mm-1, dd  
var d = new Date(2011, 01, 07, 11, 05, 00); // yyyy, mm-1, dd, hh, mm, ss  
var d = new Date("02/07/2011"); // "mm/dd/yyyy"  
var d = new Date("02/07/2011 11:05:00"); // "mm/dd/yyyy hh:mm:ss"  
var d = new Date(1297076700000); // milliseconds  
var d = new Date("Mon Feb 07 2011 11:05:00 GMT"); // ""Day Mon dd yyyy hh:mm:ss GMT/UTC 

Another way that this can be done using gmtime and format function;

from time import gmtime
print('{}-{}-{} {}:{}:{}'.format(*gmtime(1538654264.703337)))

Output: 2018-10-4 11:57:44

Regarding how to get the artifact binary, Pascal Thivent's answer is it, but to also get the artifact sources jar, we can use:

mvn dependency:get -Dartifact=groupId:artifactId:version:jar:sources

e.g.

mvn dependency:get -Dartifact=junit:junit:4.12:jar:sources

This works because the artifact parameter actually consists of groupId:artifactId:version[:packaging][:classifier]. Just the packaging and classifier are optional.

With jar as packaging and sources as classifier, the maven dependency plugin understands we're asking for the sources jar, not the artifact jar.

Unfortunately for now sources jar files cannot be downloaded transitively, which does make sense, but ideally I do believe it can also respect the option downloadSources just like the maven eclipse plugin does.

Just rename the .war into .jar and unzip it using Winrar (or any other archive manager).

As far as find BlueBearr response the best (while I,m running my batch script with eg. SYSTEM rights) I have to add something to it. Because in my Windows language version (Polish) line that is to be catched by "%%a %%b"=="User Name:" gets REALLY COMPLICATED (it contains some diacritic characters in my language) I skip first 7 lines and operate on the 8th.

@for /f "SKIP= 7 TOKENS=3,4 DELIMS=\ " %%G in ('tasklist /FI "IMAGENAME eq explorer.exe" /FO LIST /V') do @IF %%G==%COMPUTERNAME% set _currdomain_user=%%H

var fs = require('fs');

fs.readFile('ashish.json',{encoding:'utf8'},function(data,err) {

   if(err) 
      throw err;

   else {

   console.log(data.toString());

 }
})

In this case it is just coding style.

Use of var is only necessary when dealing with anonymous types.
In other situations it's a matter of taste.

Of course. if you are running on Tensorflow or CNTk backends, your code will run on your GPU devices defaultly.But if Theano backends, you can use following

"THEANO_FLAGS=device=gpu,floatX=float32 python my_keras_script.py"

Assuming all your macros are in modules, maybe this link will help. After copying the workbook, just iterate over each module and delete it

Try deleting the virtualenv you created. Then create a new virtualenv with:

virtualenv flask

Then:

cd flask

Now let's activate the virtualenv

source bin/activate

Now you should see (flask) on the left of the command line.

_{Edit: In windows there is no "source" that's a linux thing, instead execute the activate.bat file, here I do it using Powershell: PS C:\DEV\aProject> & .\Flask\Scripts\activate)}

Let's install flask:

pip install flask

Then create a file named hello.py (NOTE: see UPDATE Flask 1.0.2 below):

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":
    app.run()

and run it with:

python hello.py

UPDATE Flask 1.0.2

With the new flask release there is no need to run the app from your script. hello.py should look like this now:

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

and run it with:

FLASK_APP=hello.py flask run

Make sure to be inside the folder where hello.py is when running the latest command.

All the steps before the creation of the hello.py apply for this case as well

Quick and dirty work around which did it for me, not actually coloring the icon, but surrounding it with a label or badge in the color you want;

<span class="label-important label"><i class="icon-remove icon-white"></i></span>
<span class="label-success label"><i class="icon-ok icon-white"></i></span>

end(...[explode('.', $file_name)]) has worked since PHP 5.6. This is documented in the RFC although not in PHP docs themselves.

Here's a gist which does this: https://gist.github.com/dcollien/312bce1270a5f511bf4a

(an es6 version, and a .js version which can be included in a script tag)

You can use it as follows:

<input type="file" id="select">
<img id="preview">
<script>
document.getElementById('select').onchange = function(evt) {
    ImageTools.resize(this.files[0], {
        width: 320, // maximum width
        height: 240 // maximum height
    }, function(blob, didItResize) {
        // didItResize will be true if it managed to resize it, otherwise false (and will return the original file as 'blob')
        document.getElementById('preview').src = window.URL.createObjectURL(blob);
        // you can also now upload this blob using an XHR.
    });
};
</script>

It includes a bunch of support detection and polyfills to make sure it works on as many browsers as I could manage.

(it also ignores gif images - in case they're animated)

Try this way, almost same.. but that's what I did, and working.

<configuration>
    <system.web>
       <customErrors mode="On" defaultRedirect="apperror.aspx">
          <error statusCode="404" redirect="404.aspx" />
          <error statusCode="500" redirect="500.aspx" />
       </customErrors>
    </system.web>
</configuration> 

or try to change the 404 error page from IIS settings, if required urgently.

var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?foo=bar';
window.history.pushState({path:newurl},'',newurl);

You can also use the Uri class.

new Uri("file:///Users/smcho/filegen_from_directory/AIRPassthrough").Segments.Last()

You may prefer to use this class if you want to get some other segment, or if you want to do the same thing with a web address.

$ echo -n 'Hello world!' | hd
00000000  48 65 6c 6c 6f 20 77 6f  72 6c 64 21              |Hello world!|

Fetch all at once =

List<Integer> list = null;

if(map!= null) 
{ 
  list = new ArrayList<Integer>(map.values()); 
}

For Storing =

if(map!= null) 
{ 
  list = map.get(keyString); 
   if(list == null)
    {
         list = new ArrayList<Integer>();
    }
  list.add(value);
  map.put(keyString,list);
}

This searches multiple words in multiple files:

All good answers. To put it in simple language [BCNF] No partial key can depend on a key.

i.e No partial subset ( i.e any non trivial subset except the full set ) of a candidate key can be functionally dependent on some candidate key.

The problem is that you remove the last comma in the string, not the comma if it's the last thing in the string. So you should put an if to check if the last char is ',' and change it if it is.

EDIT: Is it really that confusing?

'This, is a random string'

Your code finds the last comma from the string and stores only 'This, ' because, the last comma is after 'This' not at the end of the string.

jQuery is not being loaded, this is not likely specific to IE8. Check the path on your jQuery include. statement. Or better yet, use the following to the CDN:

The below query worked for me in Oracle database.

select COLUMN_NAME from ALL_TAB_COLUMNS where TABLE_NAME='MyTableName';

You can query the all_tab_columns view in the database.

SELECT  table_name, column_name, data_type, data_length FROM all_tab_columns where table_name = 'CUSTOMER'

I was able to accomplish this by using bind(). I wanted to click a button in index.jsx, post some data to the server, evaluate the response, and redirect to success.jsx. Here's how I worked that out...

index.jsx:

import React, { Component } from "react"
import { postData } from "../../scripts/request"

class Main extends Component {
    constructor(props) {
        super(props)
        this.handleClick = this.handleClick.bind(this)
        this.postData = postData.bind(this)
    }

    handleClick() {
        const data = {
            "first_name": "Test",
            "last_name": "Guy",
            "email": "[email protected]"
        }

        this.postData("person", data)
    }

    render() {
        return (
            <div className="Main">
                <button onClick={this.handleClick}>Test Post</button>
            </div>
        )
    }
}

export default Main

request.js:

import { post } from "./fetch"

export const postData = function(url, data) {
    // post is a fetch() in another script...
    post(url, data)
        .then((result) => {
            if (result.status === "ok") {
                this.props.history.push("/success")
            }
        })
}

success.jsx:

import React from "react"

const Success = () => {
    return (
        <div className="Success">
            Hey cool, got it.
        </div>
    )
}

export default Success

So by binding this to postData in index.jsx, I was able to access this.props.history in request.js... then I can reuse this function in different components, just have to make sure I remember to include this.postData = postData.bind(this) in the constructor().

PDFTron WebViewer supports rendering of Word (and other Office formats) directly in any browser and without any server side dependencies. To test, try https://www.pdftron.com/webviewer/demo

I had the same error and none of your solutions helped. I think my problem was simply the name that I had chosen for the project. I had named my project 'interface' which when I got the parse error it said that it couldn't load:

Line 1: <%@ Application Codebehind="Global.asax.cs" Inherits="@interface.MvcApplication" Language="C#" %>

Where there was an '@' sign for some reason. I am guessing the word 'interface' is reserved for something else and it added the @ symbol but that obviously broke something. I deleted the project and made a new one with a different name with no problems.

What about:

if (urldecode(trim($url)) == trim($url)) { $url_form = 'decoded'; }
  else { $url_form = 'encoded'; }

Will not work with double encoding but this is out of scope anyway I suppose?

Are you calling getWidth() before the view is actually laid out on the screen?

A common mistake made by new Android developers is to use the width and height of a view inside its constructor. When a view’s constructor is called, Android doesn’t know yet how big the view will be, so the sizes are set to zero. The real sizes are calculated during the layout stage, which occurs after construction but before anything is drawn. You can use the onSizeChanged() method to be notified of the values when they are known, or you can use the getWidth() and getHeight() methods later, such as in the onDraw() method.

If you're using onCreateOptionsMenu, you can also add setTitle code in onCreateOptionsMenu.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);

    setTitle("Neue Aktivität");
    return true;
}

It is not supported in java as in other language for ex. Kotlin.

It is valid. You can, for example, use it to show modals (or similar things that respond to data-toggle and data-target attributes).

Something like:

<a role="button" data-toggle="modal" data-target=".bs-example-modal-sm" aria-hidden="true"><i class="fa fa-phone"></i></a>

Here I use the font-awesome icon, which is better as a a tag rather than a button, to show a modal. Also, setting role="button" makes the pointer change to an action type. Without either href or role="button", the cursor pointer does not change.

Try this:

_imageView.image = image;
[_imageView.layer addAnimation:[CATransition animation] forKey:kCATransition];

The following is working fine:

String path="cmd /c start d:\\sample\\sample.bat";
Runtime rn=Runtime.getRuntime();
Process pr=rn.exec(path);

Constructor The constructor is a method that's automatically called during the creation of an object from a class. ... Simply put, the constructor aids in constructing things. In React, the constructor is no different. It can be used to bind event handlers to the component and/or initializing the local state of the component.Jan 23, 2019

getInitialState In ES6 classes, you can define the initial state by assigning this.state in the constructor:

Look at this example

var Counter = createReactClass({
  getInitialState: function() {
    return {count: this.props.initialCount};
  },
  // ...
});

With createReactClass(), you have to provide a separate getInitialState method that returns the initial state:

It's a bit hard to give a definitive answer without a bit more information, but one usual way is to register a startup script:

try
{
  ...
}
catch(ApplicationException ex){
  Page.ClientScript.RegisterStartupScript(this.GetType(),"ErrorAlert","alert('Some text here - maybe ex.Message');",true);
}

Have you changed the permissions on the individual files as well as just the directory?

chmod -R 777 /home/user/xxx

$ ip route show default | awk '/default/ {print $5}'

return: eth0 (my online interface)

$ cat /sys/class/net/$(ip route show default | awk '/default/ {print $5}')/address

return: ec:a8:6b:bd:55:05 (macaddress of the eth0, my online interface)

I would rather use the Date valueOf method instead of === or !==

Seems like === is comparing internal Object's references and nothing concerning date.

Anytime you're changing the headers of an HttpWebRequest, you need to use the appropriate properties on the object itself, if they exist. If you have a plain WebRequest, be sure to cast it to an HttpWebRequest first. Then Referrer in your case can be accessed via ((HttpWebRequest)request).Referrer, so you don't need to modify the header directly - just set the property to the right value. ContentLength, ContentType, UserAgent, etc, all need to be set this way.

IMHO, this is a shortcoming on MS part...setting the headers via Headers.Add() should automatically call the appropriate property behind the scenes, if that's what they want to do.

Using Javascript you can download like this in a simple method

var oReq = new XMLHttpRequest();
// The Endpoint of your server 
var URLToPDF = "https://mozilla.github.io/pdf.js/web/compressed.tracemonkey-pldi-09.pdf";
// Configure XMLHttpRequest
oReq.open("GET", URLToPDF, true);

// Important to use the blob response type
oReq.responseType = "blob";

// When the file request finishes
// Is up to you, the configuration for error events etc.
oReq.onload = function() {
// Once the file is downloaded, open a new window with the PDF
// Remember to allow the POP-UPS in your browser
var file = new Blob([oReq.response], { 
    type: 'application/pdf' 
});

// Generate file download directly in the browser !
saveAs(file, "mypdffilename.pdf");
};

oReq.send();

Rather than abusing plot or annotate, which will be inefficient for many lines, you can use matplotlib.collections.LineCollection:

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.collections import LineCollection

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")

# Takes list of lines, where each line is a sequence of coordinates
l1 = [(70, 100), (70, 250)]
l2 = [(70, 90), (90, 200)]
lc = LineCollection([l1, l2], color=["k","blue"], lw=2)

plt.gca().add_collection(lc)

plt.show()

It takes a list of lines [l1, l2, ...], where each line is a sequence of N coordinates (N can be more than two).

The standard formatting keywords are available, accepting either a single value, in which case the value applies to every line, or a sequence of M values, in which case the value for the ith line is values[i % M].

$it = new RegexIterator(new DirectoryIterator("."), "/\\.xml\$/i"));

foreach ($it as $filename) {
    //...
}

You can also use the recursive variants of the iterators to traverse an entire directory hierarchy.

After searching the Web and trying many different ways, here's what I'd suggest for Java EE 6 authentication:

Set up the security realm:

In my case, I had the users in the database. So I followed this blog post to create a JDBC Realm that could authenticate users based on username and MD5-hashed passwords in my database table:

http://blog.gamatam.com/2009/11/jdbc-realm-setup-with-glassfish-v3.html

Note: the post talks about a user and a group table in the database. I had a User class with a UserType enum attribute mapped via javax.persistence annotations to the database. I configured the realm with the same table for users and groups, using the userType column as the group column and it worked fine.

Use form authentication:

Still following the above blog post, configure your web.xml and sun-web.xml, but instead of using BASIC authentication, use FORM (actually, it doesn't matter which one you use, but I ended up using FORM). Use the standard HTML , not the JSF .

Then use BalusC's tip above on lazy initializing the user information from the database. He suggested doing it in a managed bean getting the principal from the faces context. I used, instead, a stateful session bean to store session information for each user, so I injected the session context:

 @Resource
 private SessionContext sessionContext;

With the principal, I can check the username and, using the EJB Entity Manager, get the User information from the database and store in my SessionInformation EJB.

Logout:

I also looked around for the best way to logout. The best one that I've found is using a Servlet:

 @WebServlet(name = "LogoutServlet", urlPatterns = {"/logout"})
 public class LogoutServlet extends HttpServlet {
  @Override
  protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   HttpSession session = request.getSession(false);

   // Destroys the session for this user.
   if (session != null)
        session.invalidate();

   // Redirects back to the initial page.
   response.sendRedirect(request.getContextPath());
  }
 }

Although my answer is really late considering the date of the question, I hope this helps other people that end up here from Google, just like I did.

Ciao,

It took me a while, but here's how I made it dynamic. It doesn't depend on a sorted table.

First I started with a column of state names (Column A) and a column of aircraft in each state (Column B). (Row 1 is a header row).

Finding the cell that contains the number of aircraft was:

=MATCH(MAX($B$2:$B$54),$B$2:$B$54,0)+MIN(ROW($B$2:$B$54))-1

I put that into a cell and then gave that cell a name, "StateRow" Then using the tips from above, I wound up with this:

=INDIRECT(ADDRESS(StateRow,1))

This returns the name of the state from the dynamic value in row "StateRow", column 1

Now, as the values in the count column change over time as more data is entered, I always know which state has the most aircraft.

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

Two methods:

Method #1 (use external package)

You need to ask for the IP address that is bound to your eth0 interface. This is available from the netifaces package

import netifaces as ni
ni.ifaddresses('eth0')
ip = ni.ifaddresses('eth0')[ni.AF_INET][0]['addr']
print ip  # should print "192.168.100.37"

You can also get a list of all available interfaces via

ni.interfaces()

Method #2 (no external package)

Here's a way to get the IP address without using a python package:

import socket
import fcntl
import struct

def get_ip_address(ifname):
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(
        s.fileno(),
        0x8915,  # SIOCGIFADDR
        struct.pack('256s', ifname[:15])
    )[20:24])

get_ip_address('eth0')  # '192.168.0.110'

Note: detecting the IP address to determine what environment you are using is quite a hack. Almost all frameworks provide a very simple way to set/modify an environment variable to indicate the current environment. Try and take a look at your documentation for this. It should be as simple as doing

if app.config['ENV'] == 'production':
  #send production email
else:
  #send development email

DECLARE  @m int
SET     @m = 2

SELECT 
       @m AS [Month],
       DATEDIFF(DAY,
                DATEADD(DAY, 0, DATEADD(m, +@m -1, 0)),
                DATEADD(DAY, 0, DATEADD(m,+ @m, 0))
               ) AS [Days in Month]

For a three dimensional array you could try:

for c in array.transpose(1, 0, 2):
    do_stuff(c)

See the docs on how array.transpose works. Basically you are specifying which dimension to shift. In this case we are shifting the second dimension (e.g. columns) to the first dimension.

Yes, await / async was a great concept, but the implementation is completely broken.

For whatever reason, the await keyword has been implemented such that it can only be used within an async method. This is in fact a bug, though you will not see it referred to as such anywhere but right here. The fix for this bug would be to implement the await keyword such that it can only be used TO CALL an async function, regardless of whether the calling function is itself synchronous or asynchronous.

Due to this bug, if you use await to call a real asynchronous function somewhere in your code, then ALL of your functions must be marked as async and ALL of your function calls must use await.

This essentially means that you must add the overhead of promises to all of the functions in your entire application, most of which are not and never will be asynchronous.

If you actually think about it, using await in a function should require the function containing the await keyword TO NOT BE ASYNC - this is because the await keyword is going to pause processing in the function where the await keyword is found. If processing in that function is paused, then it is definitely NOT asynchronous.

So, to the developers of javascript and ECMAScript - please fix the await/async implementation as follows...

• await can only be used to CALL async functions.
• await can appear in any kind of function, synchronous or asynchronous.
• Change the error message from "await is only valid in async function" to "await can only be used to call async functions".

This issue appears to be causing ongoing consternation, so I will attempt to give a clearer answer than the previously posted answers, which only contain partial hints as to what's happening.

• Some time around the summer of 2014, IT Security Engineer Michele Spagnuolo (apparently employed at Google Zurich) developed a proof-of-concept exploit and supporting tool called Rosetta Flash that demonstrated a way for hackers to run malicious Flash SWF files from a remote domain in a manner which tricks browsers into thinking it came from the same domain the user was currently browsing. This allows bypassing of the "same-origin policy" and can permit hackers a variety of exploits. You can read the details here: https://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/
  • Known affected browsers: Chrome, IE
  • Possibly unaffected browsers: Firefox
• Adobe has released at least 5 different fixes over the past year while trying to comprehensively fix this vulnerability, but various major websites also introduced their own fixes earlier on in order to prevent mass vulnerability to their userbases. Among the sites to do so: Google, Youtube, Facebook, Github, and others. One component of the ad-hoc mitigation implemented by these website owners was to force the HTTP Header Content-Disposition: attachment; filename=f.txt on the returns from JSONP endpoints. This has the annoyance of causing the browser to automatically download a file called f.txt that you didn't request—but it is far better than your browser automatically running a possibly malicious Flash file.
• In conclusion, the websites you were visiting when this file spontaneously downloaded are not bad or malicious, but some domain serving content on their pages (usually ads) had content with this exploit inside it. Note that this issue will be random and intermittent in nature because even visiting the same pages consecutively will often produce different ad content. For example, the advertisement domain ad.doubleclick.net probably serves out hundreds of thousands of different ads and only a small percentage likely contain malicious content. This is why various users online are confused thinking they fixed the issue or somehow affected it by uninstalling this program or running that scan, when in fact it is all unrelated. The f.txt download just means you were protected from a recent potential attack with this exploit and you should have no reason to believe you were compromised in any way.
• The only way I'm aware that you could stop this f.txt file from being downloaded again in the future would be to block the most common domains that appear to be serving this exploit. I've put a short list below of some of the ones implicated in various posts. If you wanted to block these domains from touching your computer, you could add them to your firewall or alternatively you could use the HOSTS file technique described in the second section of this link: http://www.chromefans.org/chrome-tutorial/how-to-block-a-website-in-google-chrome.htm
• Short list of domains you could block (by no means a comprehensive list). Most of these are highly associated with adware and malware:
  • ad.doubleclick.net
  • adclick.g.doubleclick.net
  • secure-us.imrworldwide.com
  • d.turn.com
  • ad.turn.com
  • secure.insightexpressai.com

Some time ago Jupyter Notebooks started stripping JavaScript from HTML content [#3118]. Here are two solutions:

Serving Local HTML

If you want to embed an HTML page with JavaScript on your page now, the easiest thing to do is to save your HTML file to the directory with your notebook and then load the HTML as follows:

from IPython.display import IFrame

IFrame(src='./nice.html', width=700, height=600)

Serving Remote HTML

If you prefer a hosted solution, you can upload your HTML page to an Amazon Web Services "bucket" in S3, change the settings on that bucket so as to make the bucket host a static website, then use an Iframe component in your notebook:

from IPython.display import IFrame

IFrame(src='https://s3.amazonaws.com/duhaime/blog/visualizations/isolation-forests.html', width=700, height=600)

This will render your HTML content and JavaScript in an iframe, just like you can on any other web page:

<iframe src='https://s3.amazonaws.com/duhaime/blog/visualizations/isolation-forests.html', width=700, height=600></iframe>

In case your app needs to work on files (what you would normally expect to pass as: ./myApp *.jpg), you would do it like this:

open *.jpg -a myApp

While <strong> and <em> are of course more semantically correct, there seem definite legitimate reasons to use the <b> and <i> tags for customer-written content.

In such content, words or phrases may be bolded or italicized and it is generally not up to us to analyze the semantic reasoning for such bolding or italicizing.

Further, such content may refer to bolded and italicized words and phrases to convey a specific meaning.

An example would be an english exam question which instructs a student to replace the bolded word.

SOLUTION

The following code worked for me with jQuery. It works in every browser and allows to preserve events and custom properties.

var $el = $('#uploadCaptureInputFile');
$el.wrap('<form>').closest('form').get(0).reset();
$el.unwrap();

One bizarre thing is that in Chrome + Firefox, the MOUSE_LEAVE event isn't dispatched for OPAQUE and TRANSPARENT.

With WINDOW it works fine. That one took some time to find out! grr...

(note: jediericb mentioned this bug - which is similar but doesn't mention MOUSE_LEAVE)

Put your domain name here: https://www.ssllabs.com/ssltest/analyze.html You should be able to see if there are any issues with your ssl certificate chain. I am guessing that you have SSL chain issues. A short description of the problem is that there's actually a list of certificates on your server (and not only one) and these need to be in the correct order. If they are there but not in the correct order, the website will be fine on desktop browsers (an iOs as well I think), but android is more strict about the order of certificates, and will give an error if the order is incorrect. To fix this you just need to re-order the certificates.

I'm resurrecting this because I was researching a non-JavaScript way to do this. I wasn't into the key handlers, and the CSS positioning stuff was causing tab ordering to break since CSS repositioning doesn't change tab order.

My solution is based on the response at https://stackoverflow.com/a/9491141.

The solution source is below. tabindex is used to correct tab behaviour of the hidden button, as well as aria-hidden to avoid having the button read out by screen readers / identified by assistive devices.

<form method="post" action="">
  <button type="submit" name="useraction" value="2nd" class="default-button-handler" aria-hidden="true" tabindex="-1"></button>
  <div class="form-group">
    <label for="test-input">Focus into this input: </label>
    <input type="text" id="test-input" class="form-control" name="test-input" placeholder="Focus in here and press enter / go" />
  </div>

1st button in DOM 2nd button in DOM 3rd button in DOM

Essential CSS for this solution:

.default-button-handler {
  width: 0;
  height: 0;
  padding: 0;
  border: 0;
  margin: 0;
}

Just remember to add quotes into the path if you have a space in your path to java home. C:\Program Files\java\javaxxx\ doesn't work but "C:\Program Files\java\javaxxx\" does.

The numbers starting with 0x are hexadecimal (base 16).0x6400 represents 25600.

To convert,

• multiply the last digit times 1
• add second-last digit times 16 (16^1)
• add third-last digit times 256 (16^2)
• add fourth-last digit times 4096 (16^3)
• ...and so on

The factors 1, 16, 256, etc. are the increasing powers of 16.

0x6400 = (0*1) + (0*16^1) + (4*16^2) + (6*16^3) = 25600 

or

0x6400 = (0*1) + (0*16) + (4*256) + (6*4096) = 25600 

%r shows with quotes:

It will be like:

I said: 'There are 10 types of people.'.

If you had used %s it would have been:

I said: There are 10 types of people..

Result Set are actually contains multiple rows of data, and use a cursor to point out current position. So in your case, rs4.getString(1) only get you the data in first column of first row. In order to change to next row, you need to call next()

a quick example

while (rs.next()) {
    String sid = rs.getString(1);
    String lid = rs.getString(2);
    // Do whatever you want to do with these 2 values
}

there are many useful method in ResultSet, you should take a look :)

As long as you override equals() on each key and value contained in the map, then m1.equals(m2) should be reliable to check for maps equality.

The same result can be obtained also by comparing toString() of each map as you suggested, but using equals() is a more intuitive approach.

May not be your specific situation, but if you store arrays in the map, may be a little tricky, because they must be compared value by value, or using Arrays.equals(). More details about this see here.

Use diskpart.exe.

Once you are in diskpart select volume <VolumeNumber> then type filesystems.

It should tell you the file system type and the allocation unit size. It will also tell you the supported sizes etc. Previously mentioned fsutil does work, but answer isn't as clear and I couldn't find a syntax to get the same information for a junction point.

I finally figured out a how to use Maven. From within Eclipse, create a new Maven project.

Download Maven, extract the archive, add the /bin folder to path.

Validate install from command-line by running mvn -v (will print version and java install path)

Change to the project root folder (where pom.xml is located) and run:

mvn dependency:copy-dependencies

All jar-files are downloaded to /target/dependency.

To set another output directory:

mvn dependency:copy-dependencies -DoutputDirectory="c:\temp"

Now it's possible to re-use this Maven-project for all dependency downloads by altering the pom.xml

Add jars to java project by build path -> configure build path -> libraries -> add JARs..

Here is the actual code that does it...

$(document).ready(function()
{
  var oTable = $('#myTable').dataTable();

  // Sort immediately with column 2 (at position 1 in the array (base 0). More could be sorted with additional array elements
  oTable.fnSort( [ [1,'asc'] ] );

  // And to sort another column descending (at position 2 in the array (base 0).
  oTable.fnSort( [ [2,'desc'] ] );
} );

To not have the column highlighted, modify the CSS like so:

table.dataTable tr.odd td.sorting_1 { background-color: transparent; }
table.dataTable tr.even td.sorting_1 { background-color: transparent; }

The Swiss Army knife of image lazy loading is YUI's ImageLoader.

Because there is more to this problem than simply watching the scroll position.

well good question but when the source code is changed into intermediate native byte code by a compiler in which it converts the program into the byte code by giving the errors after the whole checking at once (if found) and then the program needs a interpreter which would check the program line by line and directly change it into machine code or object code and each operating system by default cannot have an java interpreter because of some security reasons so you need to have jvm at any cost to run it in that different O.S platform independence as you said here means that the program can be run in any os like unix, mac, linux, windows, etc but this does not mean that each and every os will be able to run the codes without a jvm which saysspecification, implementation, and instance , if i advance then by changing the configuration of your pc so that you can have a class loader that can open even the byte code then also you can execute java byte code, applets, etc. -by nimish :) best of luck

I'd like to share my own work that is faster than Manager's dict and is simpler and more stable than pyshmht library that uses tons of memory and doesn't work for Mac OS. Though my dict only works for plain strings and is immutable currently. I use linear probing implementation and store keys and values pairs in a separate memory block after the table.

from mmap import mmap
import struct
from timeit import default_timer
from multiprocessing import Manager
from pyshmht import HashTable


class shared_immutable_dict:
    def __init__(self, a):
        self.hs = 1 << (len(a) * 3).bit_length()
        kvp = self.hs * 4
        ht = [0xffffffff] * self.hs
        kvl = []
        for k, v in a.iteritems():
            h = self.hash(k)
            while ht[h] != 0xffffffff:
                h = (h + 1) & (self.hs - 1)
            ht[h] = kvp
            kvp += self.kvlen(k) + self.kvlen(v)
            kvl.append(k)
            kvl.append(v)

        self.m = mmap(-1, kvp)
        for p in ht:
            self.m.write(uint_format.pack(p))
        for x in kvl:
            if len(x) <= 0x7f:
                self.m.write_byte(chr(len(x)))
            else:
                self.m.write(uint_format.pack(0x80000000 + len(x)))
            self.m.write(x)

    def hash(self, k):
        h = hash(k)
        h = (h + (h >> 3) + (h >> 13) + (h >> 23)) * 1749375391 & (self.hs - 1)
        return h

    def get(self, k, d=None):
        h = self.hash(k)
        while True:
            x = uint_format.unpack(self.m[h * 4:h * 4 + 4])[0]
            if x == 0xffffffff:
                return d
            self.m.seek(x)
            if k == self.read_kv():
                return self.read_kv()
            h = (h + 1) & (self.hs - 1)

    def read_kv(self):
        sz = ord(self.m.read_byte())
        if sz & 0x80:
            sz = uint_format.unpack(chr(sz) + self.m.read(3))[0] - 0x80000000
        return self.m.read(sz)

    def kvlen(self, k):

uint_format = struct.Struct('>I')


def uget(a, k, d=None):
    return to_unicode(a.get(to_str(k), d))

def to_unicode(s):
    return s.decode('utf-8') if isinstance(s, str) else s

    return s.encode('utf-8') if isinstance(s, unicode) else s


def mmap_test():

    start_time = default_timer()
    for i in xrange(n):
        if bool(d.get(str(i))) != (i % 2 == 0):
            raise Exception(i)
    print 'mmap speed: %d gets per sec' % (n / (default_timer() - start_time))


def manager_test():
    n = 100000
    d = Manager().dict({str(i * 2): '1' for i in xrange(n)})
    start_time = default_timer()
    for i in xrange(n):
        if bool(d.get(str(i))) != (i % 2 == 0):
            raise Exception(i)

if __name__ == '__main__':
    mmap_test()
    manager_test()
    shm_test()

On my laptop performance results are:

mmap speed: 247288 gets per sec
manager speed: 33792 gets per sec
shm speed: 691332 gets per sec

simple usage example:

ht = shared_immutable_dict({'a': '1', 'b': '2'})
print ht.get('a')

I realize this was long ago answered but want to suggest an additional approach that avoids the nested try-with-resources double block.

public List<User> getUser(int userId) {
    try (Connection con = DriverManager.getConnection(myConnectionURL);
         PreparedStatement ps = createPreparedStatement(con, userId); 
         ResultSet rs = ps.executeQuery()) {

         // process the resultset here, all resources will be cleaned up

    } catch (SQLException e) {
        e.printStackTrace();
    }
}

private PreparedStatement createPreparedStatement(Connection con, int userId) throws SQLException {
    String sql = "SELECT id, username FROM users WHERE id = ?";
    PreparedStatement ps = con.prepareStatement(sql);
    ps.setInt(1, userId);
    return ps;
}

In pure Python:

def get_param_from_url(url, param_name):
    return [i.split("=")[-1] for i in url.split("?", 1)[-1].split("&") if i.startswith(param_name + "=")][0]

(trunc(random() * 10) % 10) + 1

//random numbers are 0,1,2,3 
ArrayList<Integer> numbers = new ArrayList<Integer>();   
Random randomGenerator = new Random();
while (numbers.size() < 4) {

    int random = randomGenerator .nextInt(4);
    if (!numbers.contains(random)) {
        numbers.add(random);
    }
}

Add a try/catch block, if the transaction succeeds it will commit the changes, if the transaction fails the transaction is rolled back:

BEGIN TRANSACTION [Tran1]

  BEGIN TRY

      INSERT INTO [Test].[dbo].[T1] ([Title], [AVG])
      VALUES ('Tidd130', 130), ('Tidd230', 230)

      UPDATE [Test].[dbo].[T1]
      SET [Title] = N'az2' ,[AVG] = 1
      WHERE [dbo].[T1].[Title] = N'az'

      COMMIT TRANSACTION [Tran1]

  END TRY

  BEGIN CATCH

      ROLLBACK TRANSACTION [Tran1]

  END CATCH  

Joe Edel's answer to himself is actually the right approach to resolve the pivot problem.

Basically the idea is to list out the columns in the base table firstly, and then any number of options.value from the joint option table. Just left join the same option table multiple times in order to get all the options.

What needs to be done by the programming language is to build this query dynamically according to a list of options needs to be queried.

If you installed the command line tools separately, delete them using:

sudo rm -rf /Library/Developer/CommandLineTools

Use the modulus operator %, it returns the remainder.

int a = 5;
int b = 3;

if (a % b != 0) {
   printf("The remainder is: %i", a%b);
}

The script containing variables can be executed imported using bash. Consider the script-variable.sh

#!/bin/sh
scr-var=value

Consider the actual script where the variable will be used :

 #!/bin/sh
 bash path/to/script-variable.sh
 echo "$scr-var"

In Git, "origin" is a shorthand name for the remote repository that a project was originally cloned from. More precisely, it is used instead of that original repository's URL - and thereby makes referencing much easier.

Another way to look at this would be to use mongoDB You can store your JSON in mongo and then query it via the mongodb query syntax.

Without opening an IDE to check my brain works properly for syntax at this time of day...

If you simply want the date in a particular format you can use DateTime's .ToString(string format). There are a number of examples of standard and custom formatting strings if you follow that link.

So

DateTime _date = DateTime.Now;
var _dateString = _date.ToString("dd/MM/yyyy");

would give you the date as a string in the format you request.
