Your code works fine. You can verify the RGB colors with Iconfactory's xScope. Just compare it to [UIColor whiteColor].

I have build such kind of application using approximatively the same approach except :

• I cache the generated image on the disk and always generate two to three images in advance in a separate thread.
• I don't overlay with a UIImage but instead draw the image in the layer when zooming is 1. Those tiles will be released automatically when memory warnings are issued.

Whenever the user start zooming, I acquire the CGPDFPage and render it using the appropriate CTM. The code in - (void)drawLayer: (CALayer*)layer inContext: (CGContextRef) context is like :

CGAffineTransform currentCTM = CGContextGetCTM(context);    
if (currentCTM.a == 1.0 && baseImage) {
    //Calculate ideal scale
    CGFloat scaleForWidth = baseImage.size.width/self.bounds.size.width;
    CGFloat scaleForHeight = baseImage.size.height/self.bounds.size.height; 
    CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight);

    CGSize imageSize = CGSizeMake(baseImage.size.width/imageScaleFactor, baseImage.size.height/imageScaleFactor);
    CGRect imageRect = CGRectMake((self.bounds.size.width-imageSize.width)/2, (self.bounds.size.height-imageSize.height)/2, imageSize.width, imageSize.height);
    CGContextDrawImage(context, imageRect, [baseImage CGImage]);
} else {
    @synchronized(issue) { 
        CGPDFPageRef pdfPage = CGPDFDocumentGetPage(issue.pdfDoc, pageIndex+1);
        pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, layer.bounds, 0, true);
        CGContextConcatCTM(context, pdfToPageTransform);    
        CGContextDrawPDFPage(context, pdfPage);
    }
}

issue is the object containg the CGPDFDocumentRef. I synchronize the part where I access the pdfDoc property because I release it and recreate it when receiving memoryWarnings. It seems that the CGPDFDocumentRef object do some internal caching that I did not find how to get rid of.

iOS 7 has a new method that allows you to draw a view hierarchy into the current graphics context. This can be used to get an UIImage very fast.

I implemented a category method on UIView to get the view as an UIImage:

- (UIImage *)pb_takeSnapshot {
    UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, [UIScreen mainScreen].scale);

    [self drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES];

    // old style [self.layer renderInContext:UIGraphicsGetCurrentContext()];

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

It is considerably faster then the existing renderInContext: method.

Reference: https://developer.apple.com/library/content/qa/qa1817/_index.html

UPDATE FOR SWIFT: An extension that does the same:

extension UIView {

    func pb_takeSnapshot() -> UIImage {
        UIGraphicsBeginImageContextWithOptions(bounds.size, false, UIScreen.mainScreen().scale)

        drawViewHierarchyInRect(self.bounds, afterScreenUpdates: true)

        // old style: layer.renderInContext(UIGraphicsGetCurrentContext())

        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image
    }
}

UPDATE FOR SWIFT 3

    UIGraphicsBeginImageContextWithOptions(bounds.size, false, UIScreen.main.scale)

    drawHierarchy(in: self.bounds, afterScreenUpdates: true)

    let image = UIGraphicsGetImageFromCurrentImageContext()!
    UIGraphicsEndImageContext()
    return image

If you want to add a photo rotate button that'll keep rotating the photo in 90 degree increments, here you go. (finalImage is a UIImage that's already been created elsewhere.)

- (void)rotatePhoto {
    UIImage *rotatedImage;

    if (finalImage.imageOrientation == UIImageOrientationRight)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationDown];
    else if (finalImage.imageOrientation == UIImageOrientationDown)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationLeft];
    else if (finalImage.imageOrientation == UIImageOrientationLeft)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationUp];
    else
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                                     scale: 1.0
                                               orientation: UIImageOrientationRight];
    finalImage = rotatedImage;
}

Swift 3

extension UIView {
    func installShadow() {
        layer.cornerRadius = 2
        layer.masksToBounds = false
        layer.shadowColor = UIColor.black.cgColor
        layer.shadowOffset = CGSize(width: 0, height: 1)
        layer.shadowOpacity = 0.45
        layer.shadowPath = UIBezierPath(rect: bounds).cgPath
        layer.shadowRadius = 1.0
    }
}

I'm not sure for UIImage, but this kind of behaviour usually occurs when coordinates are flipped. Most of OS X coordinate systems have their origin at the lower left corner, as in Postscript and PDF. But CGImage coordinate system has its origin at the upper left corner.

Possible solutions may involve an isFlipped property or a scaleYBy:-1 affine transform.

The way to approach this is to tell the tableView to remove and add rows and sections with the

insertRowsAtIndexPaths:withRowAnimation:,
deleteRowsAtIndexPaths:withRowAnimation:,
insertSections:withRowAnimation: and
deleteSections:withRowAnimation:

methods of UITableView.

When you call these methods, the table will animate in/out the items you requested, then call reloadData on itself so you can update the state after this animation. This part is important - if you animate away everything but don't change the data returned by the table's dataSource, the rows will appear again after the animation completes.

So, your application flow would be:

[self setTableIsInSecondState:YES];

[myTable deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:YES]];

As long as your table's dataSource methods return the correct new set of sections and rows by checking [self tableIsInSecondState] (or whatever), this will achieve the effect you're looking for.

server {
  server_name example.com;
  root /path/to/root;
  location / {
    # bla bla
  }
  location /demo {
    alias /path/to/root/production/folder/here;
  }
}

If you need to use try_files inside /demo you'll need to replace alias with a root and do a rewrite because of the bug explained here

The equals (=) operator is a "comparison operator compares two values for equality." In other words, in an SQL statement, it won't return true unless both sides of the equation are equal. For example:

SELECT * FROM Store WHERE Quantity = 200;

The LIKE operator "implements a pattern match comparison" that attempts to match "a string value against a pattern string containing wild-card characters." For example:

SELECT * FROM Employees WHERE Name LIKE 'Chris%';

LIKE is generally used only with strings and equals (I believe) is faster. The equals operator treats wild-card characters as literal characters. The difference in results returned are as follows:

SELECT * FROM Employees WHERE Name = 'Chris';

And

SELECT * FROM Employees WHERE Name LIKE 'Chris';

Would return the same result, though using LIKE would generally take longer as its a pattern match. However,

SELECT * FROM Employees WHERE Name = 'Chris%';

And

SELECT * FROM Employees WHERE Name LIKE 'Chris%';

Would return different results, where using "=" results in only results with "Chris%" being returned and the LIKE operator will return anything starting with "Chris".

Hope that helps. Some good info can be found here.

Using the class:

import android.provider.MediaStore.Video.Thumbnails;

We can get two preview thumbnail sizes from the video:

Thumbnails.MICRO_KIND for 96 x 96

Thumbnails.MINI_KIND for 512 x 384 px

This is a code example:

String filePath = "/sdcard/DCIM/Camera/my_video.mp4"; //change the location of your file!

ImageView imageview_mini = (ImageView)findViewById(R.id.thumbnail_mini);
ImageView imageview_micro = (ImageView)findViewById(R.id.thumbnail_micro);

Bitmap bmThumbnail;

//MICRO_KIND, size: 96 x 96 thumbnail
bmThumbnail = ThumbnailUtils.createVideoThumbnail(filePath, Thumbnails.MICRO_KIND);
imageview_micro.setImageBitmap(bmThumbnail);
     
// MINI_KIND, size: 512 x 384 thumbnail 
bmThumbnail = ThumbnailUtils.createVideoThumbnail(filePath, Thumbnails.MINI_KIND);
imageview_mini.setImageBitmap(bmThumbnail);

I agree with pjco. The best way is the official method explained in Support Library Setup in the tutorial at developer.android.com.

Then, in the Eclipse "package explorer", expand your main project and delete android-support-v4.jar from the "libs" folder (as Pratik Butani suggested).

This worked for me.

swift solution

yourlabel.text = yourvariable

or self is use for when you are in async {brackets} or in some Extension

DispatchQueue.main.async{
    self.yourlabel.text = "typestring"
}

from datetime import datetime

date = datetime.today().date()

print(date)

You can try delete project via Google Cloud Platform https://console.cloud.google.com/iam-admin/projects

Select required project and click DELETE PROJECT. The project will be completely deleted after 7 days

You can convert a string to a file object using io.StringIO and then pass that to the csv module:

from io import StringIO
import csv

scsv = """text,with,Polish,non-Latin,letters
1,2,3,4,5,6
a,b,c,d,e,f
ges,zólty,waz,idzie,waska,drózka,
"""

f = StringIO(scsv)
reader = csv.reader(f, delimiter=',')
for row in reader:
    print('\t'.join(row))

simpler version with split() on newlines:

reader = csv.reader(scsv.split('\n'), delimiter=',')
for row in reader:
    print('\t'.join(row))

Or you can simply split() this string into lines using \n as separator, and then split() each line into values, but this way you must be aware of quoting, so using csv module is preferred.

On Python 2 you have to import StringIO as

from StringIO import StringIO

instead.

I would generally prefer something a bit simpler, like activate/deactivate sub-resource (linked by a Link header with rel=service).

POST /groups/api/v1/groups/{group id}/activate

or

POST /groups/api/v1/groups/{group id}/deactivate

For the consumer, this interface is dead-simple, and it follows REST principles without bogging you down in conceptualizing "activations" as individual resources.

Answer in Swift 5 (Continuation of Ricky's answer in Swift)

Add the UIGestureRecognizerDelegate to your ViewController

 override func viewDidLoad() {
    super.viewDidLoad()

    //Long Press
    let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress))
    longPressGesture.minimumPressDuration = 0.5
    self.tableView.addGestureRecognizer(longPressGesture)
 }

And the function:

@objc func handleLongPress(longPressGesture: UILongPressGestureRecognizer) {
    let p = longPressGesture.location(in: self.tableView)
    let indexPath = self.tableView.indexPathForRow(at: p)
    if indexPath == nil {
        print("Long press on table view, not row.")
    } else if longPressGesture.state == UIGestureRecognizer.State.began {
        print("Long press on row, at \(indexPath!.row)")
    }
}

Try each_with_index.

Even if you do the following steps you COULD get the same error message.

1. login as SA user (SSMS)
2. Edit the file permissions to say "everyone" full access (windows folder)
3. Delete the Log file (Windows Exploring  (this was what I had done per advise from some msdn forum) 

I still GOT the permission error, but then I noticed that in the Attach screen, the bottom section STILL showed the LOG file, and the error message remained the same.

Hope this helps someone who did the same thing.

You can use the function glob.glob() or glob.iglob() directly from glob module to retrieve paths recursively from inside the directories/files and subdirectories/subfiles.

Syntax:

glob.glob(pathname, *, recursive=False) # pathname = '/path/to/the/directory' or subdirectory
glob.iglob(pathname, *, recursive=False)

In your example, it is possible to write like this:

import glob
import os

configfiles = [f for f in glob.glob("C:/Users/sam/Desktop/*.txt")]

for f in configfiles:
    print(f'Filename with path: {f}')
    print(f'Only filename: {os.path.basename(f)}')
    print(f'Filename without extensions: {os.path.splitext(os.path.basename(f))[0]}')

Output:

Filename with path: C:/Users/sam/Desktop/test_file.txt
Only filename: test_file.txt
Filename without extensions: test_file

If you don't want to change preferences, you can optimize imports by pressing Ctrl+Option+o on Mac or Ctrl+Alt+o on Windows/Linux and this will replace all imports with single imports in current file.

gcc 9.3 asm output, without using optimisation flags (everything in this answer refers to standard compilation without optimisation flags):

#include <stdio.h>
int main(void) {
  int i = 3;
  i++;
  printf("%d", i);
  return 0;
}

.LC0:
        .string "%d"
main:
        push    rbp
        mov     rbp, rsp
        sub     rsp, 16
        mov     DWORD PTR [rbp-4], 3
        add     DWORD PTR [rbp-4], 1
        mov     eax, DWORD PTR [rbp-4]
        mov     esi, eax
        mov     edi, OFFSET FLAT:.LC0
        mov     eax, 0
        call    printf
        mov     eax, 0
        leave 
        ret

#include <stdio.h>
int main(void) {
  register int i = 3;
  i++;
  printf("%d", i);
  return 0;
}

.LC0:
        .string "%d"
main:
        push    rbp
        mov     rbp, rsp
        push    rbx
        sub     rsp, 8
        mov     ebx, 3
        add     ebx, 1
        mov     esi, ebx
        mov     edi, OFFSET FLAT:.LC0
        mov     eax, 0
        call    printf
        add     rsp, 8
        pop     rbx
        pop     rbp
        ret

This forces ebx to be used for the calculation, meaning it needs to be pushed to the stack and restored at the end of the function because it is callee saved. register produces more lines of code and 1 memory write and 1 memory read (although realistically, this could have been optimised to 0 R/Ws if the calculation had been done in esi, which is what happens using C++'s const register). Not using register causes 2 writes and 1 read (although store to load forwarding will occur on the read). This is because the value has to be present and updated directly on the stack so the correct value can be read by address (pointer). register doesn't have this requirement and cannot be pointed to. const and register are basically the opposite of volatile and using volatile will override the const optimisations at file and block scope and the register optimisations at block-scope. const register and register will produce identical outputs because const does nothing on C at block-scope, so only the register optimisations apply.

On clang, register is ignored but const optimisations still occur.

To delete a folder even if it might not exist (avoiding the race condition in Charles Chow's answer) but still have errors when other things go wrong (e.g. permission problems, disk read error, the file isn't a directory)

For Python 3.x:

import shutil

def ignore_absent_file(func, path, exc_inf):
    except_instance = exc_inf[1]
    if isinstance(except_instance, FileNotFoundError):
        return
    raise except_instance

shutil.rmtree(dir_to_delete, onerror=ignore_absent_file)

The Python 2.7 code is almost the same:

import shutil
import errno

def ignore_absent_file(func, path, exc_inf):
    except_instance = exc_inf[1]
    if isinstance(except_instance, OSError) and \
        except_instance.errno == errno.ENOENT:
        return
    raise except_instance

shutil.rmtree(dir_to_delete, onerror=ignore_absent_file)

The following is a concise (and updated) summation of the earlier solutions. Here's what to do:

Add these strings and their respective parent keys:

pwrshell\(Default) < Open PowerShell Here
pwrshell\command\(Default) < powershell -NoExit -Command Set-Location -LiteralPath '%V'
pwrshelladmin\(Default) < Open PowerShell (Admin)
pwrshelladmin\command\(Default) < powershell -Command Start-Process -verb runAs -ArgumentList '-NoExit','cd','%V' powershell

at these locations

HKCR\Directory\shell (for folders)
HKCR\Directory\Background\shell (Explorer window)
HKCR\Drive\shell (for root drives)

That's it. Add the "Extended" strings for the commands only to be visible if you hold the "Shift" key, everything else is superfluous.

You need to declare the type of the protocol as AnyObject.

protocol ProtocolNameDelegate: AnyObject {
    // Protocol stuff goes here
}

class SomeClass {
    weak var delegate: ProtocolNameDelegate?
}

Using AnyObject you say that only classes can conform to this protocol, whereas structs or enums can't.

@Controller
public class HomeController {

    @RequestMapping(method = RequestMethod.GET, value = "/")
    public ModelAndView welcome() {
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("login.html");
        return modelAndView;
    }
}

This will return the Login.html File. The Login.html should be inside the static Folder.

Note: thymeleaf dependency is not added

@RestController
public class HomeController {

    @RequestMapping(method = RequestMethod.GET, value = "/")
    public String welcome() {
        return "login";
    }
}

This will return the String login

for i in count: means for i in 7:, which won't work. The bit after the in should be of an iterable type, not a number. Try this:

for i in range(count):

just before read key check it like before read

JSONObject json_obj=new JSONObject(yourjsonstr);
if(!json_obj.isNull("club"))
{
  //it's contain value to be read operation
}
else

  //it's not contain key club or isnull so do this operation here
}

Did you dispatch the event correctly?

function simulateKeyEvent(character) {
  var evt = document.createEvent("KeyboardEvent");
  (evt.initKeyEvent || evt.initKeyboardEvent)("keypress", true, true, window,
                    0, 0, 0, 0,
                    0, character.charCodeAt(0)) 
  var canceled = !body.dispatchEvent(evt);
  if(canceled) {
    // A handler called preventDefault
    alert("canceled");
  } else {
    // None of the handlers called preventDefault
    alert("not canceled");
  }
}

If you use jQuery, you could do:

function simulateKeyPress(character) {
  jQuery.event.trigger({ type : 'keypress', which : character.charCodeAt(0) });
}

This seems to explain it.

The definition of order is that a[order(a)] is in increasing order. This works with your example, where the correct order is the fourth, second, first, then third element.

You may have been looking for rank, which returns the rank of the elements
R> a <- c(4.1, 3.2, 6.1, 3.1)
R> order(a)
[1] 4 2 1 3
R> rank(a)
[1] 3 2 4 1
so rank tells you what order the numbers are in, order tells you how to get them in ascending order.

plot(a, rank(a)/length(a)) will give a graph of the CDF. To see why order is useful, though, try plot(a, rank(a)/length(a),type="S") which gives a mess, because the data are not in increasing order

If you did
oo<-order(a)
plot(a[oo],rank(a[oo])/length(a),type="S")
or simply
oo<-order(a)
plot(a[oo],(1:length(a))/length(a)),type="S")
you get a line graph of the CDF.

I'll bet you're thinking of rank.

You can use as the following code;

cd /my_folder && \
rm *.jar && \
svn co path to repo && \
mvn compile package install

It works...

Here's a more interesting implementation of multi line lambdas. It's not possible to achieve because of how python use indents as a way to structure code.

But luckily for us, indent formatting can be disabled using arrays and parenthesis.

As some already pointed out, you can write your code as such:

lambda args: (expr1, expr2,... exprN)

In theory if you're guaranteed to have evaluation from left to right it would work but you still lose values being passed from one expression to an other.

One way to achieve that which is a bit more verbose is to have

lambda args: [lambda1, lambda2, ..., lambdaN]

Where each lambda receives arguments from the previous one.

def let(*funcs):
    def wrap(args):
        result = args                                                                                                                                                                                                                         
        for func in funcs:
            if not isinstance(result, tuple):
                result = (result,)
            result = func(*result)
        return result
    return wrap

This method let you write something that is a bit lisp/scheme like.

So you can write things like this:

let(lambda x, y: x+y)((1, 2))

A more complex method could be use to compute the hypotenuse

lst = [(1,2), (2,3)]
result = map(let(
  lambda x, y: (x**2, y**2),
  lambda x, y: (x + y) ** (1/2)
), lst)

This will return a list of scalar numbers so it can be used to reduce multiple values to one.

Having that many lambda is certainly not going to be very efficient but if you're constrained it can be a good way to get something done quickly then rewrite it as an actual function later.

delimiter: ":","-","."

double or single: 00 = 0, 0f = f

/^([0-9a-f]{1,2}[\.:-]){5}([0-9a-f]{1,2})$/i

or

/^([0-9a-F]{1,2}[\.:-]){5}([0-9a-F]{1,2})$/

exm: 00:27:0e:2a:b9:aa, 00-27-0E-2A-B9-AA, 0.27.e.2a.b9.aa ...

It's better to use script module for that:
http://docs.ansible.com/script_module.html

Another "trick" for generating the column list is simply to drag the "Columns" node from Object Explorer onto a query window.

You should pass the reference to request like below

var options = { ... }_x000D_
var req = http.request(options, function(res) {_x000D_
  // Usual stuff: on(data), on(end), chunks, etc..._x000D_
});_x000D_
_x000D_
req.setTimeout(60000, function(){_x000D_
    this.abort();_x000D_
}).bind(req);_x000D_
req.write('something');_x000D_
req.end();

Request error event will get triggered

req.on("error", function(e){_x000D_
       console.log("Request Error : "+JSON.stringify(e));_x000D_
  });

In my case, where the timezones are not available on the server, this works great:

SELECT CONVERT_TZ(`date_field`,'+00:00',@@global.time_zone) FROM `table`

Note: global.time_zone uses the server timezone. You have to make sure, that it has the desired timezone!

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

Sub Mail_Selection_Range_Outlook_Body()

Dim rng As Range
Dim OutApp As Object
Dim OutMail As Object

Set rng = Nothing
' Only send the visible cells in the selection.

Set rng = Sheets("Sheet1").Range("D4:D12").SpecialCells(xlCellTypeVisible)

If rng Is Nothing Then
    MsgBox "The selection is not a range or the sheet is protected. " & _
           vbNewLine & "Please correct and try again.", vbOKOnly
    Exit Sub
End If

With Application
    .EnableEvents = False
    .ScreenUpdating = False
End With

Set OutApp = CreateObject("Outlook.Application")

It is not necessary that onRestoreInstanceState will always be called after onSaveInstanceState.

Note that : onRestoreInstanceState will always be called, when activity is rotated (when orientation is not handled) or open your activity and then open other apps so that your activity instance is cleared from memory by OS.

Try below piece of code.

this.dataGridView1.RefreshEdit();

Store it in multi valued column with a comma separator in an RDBMs table.

Depending upon the design being produced, each of the below clearfix CSS solutions has its own benefits.

The clearfix does have useful applications but it has also been used as a hack. Before you use a clearfix perhaps these modern css solutions can be useful:

• css flexbox
• css grid

Modern Clearfix Solutions

Container with overflow: auto;

The simplest way to clear floated elements is using the style overflow: auto on the containing element. This solution works in every modern browsers.

<div style="overflow: auto;">
  <img
    style="float: right;"
    src="path/to/floated-element.png"
    width="500"
    height="500"
  > 
  <p>Your content here…</p>
</div>

One downside, using certain combinations of margin and padding on the external element can cause scrollbars to appear but this can be solved by placing the margin and padding on another parent containing element.

Using ‘overflow: hidden’ is also a clearfix solution, but will not have scrollbars, however using hidden will crop any content positioned outside of the containing element.

Note: The floated element is an img tag in this example, but could be any html element.

Clearfix Reloaded

Thierry Koblentz on CSSMojo wrote: The very latest clearfix reloaded. He noted that by dropping support for oldIE, the solution can be simplified to one css statement. Additionally, using display: block (instead of display: table) allows margins to collapse properly when elements with clearfix are siblings.

.container::after {
  content: "";
  display: block;
  clear: both;
}

This is the most modern version of the clearfix.

Older Clearfix Solutions

The below solutions are not necessary for modern browsers, but may be useful for targeting older browsers.

Note that these solutions rely upon browser bugs and therefore should be used only if none of the above solutions work for you.

They are listed roughly in chronological order.

"Beat That ClearFix", a clearfix for modern browsers

Thierry Koblentz' of CSS Mojo has pointed out that when targeting modern browsers, we can now drop the zoom and ::before property/values and simply use:

.container::after {
    content: "";
    display: table;
    clear: both;
}

This solution does not support for IE 6/7 …on purpose!

Thierry also offers: "A word of caution: if you start a new project from scratch, go for it, but don’t swap this technique with the one you have now, because even though you do not support oldIE, your existing rules prevent collapsing margins."

Micro Clearfix

The most recent and globally adopted clearfix solution, the Micro Clearfix by Nicolas Gallagher.

Known support: Firefox 3.5+, Safari 4+, Chrome, Opera 9+, IE 6+

.container::before, .container::after {
  content: "";
  display: table;
}
.container::after {
  clear: both;
}
.container {
  zoom: 1;
}

Overflow Property

This basic method is preferred for the usual case, when positioned content will not show outside the bounds of the container.

http://www.quirksmode.org/css/clearing.html - explains how to resolve common issues related to this technique, namely, setting width: 100% on the container.

.container {
  overflow: hidden;
  display: inline-block;
  display: block;
}

Rather than using the display property to set "hasLayout" for IE, other properties can be used for triggering "hasLayout" for an element.

.container {
  overflow: hidden;
  zoom: 1;
  display: block;
}

Another way to clear floats using the overflow property is to use the underscore hack. IE will apply the values prefixed with the underscore, other browsers will not. The zoom property triggers hasLayout in IE:

.container {
  overflow: hidden;
  _overflow: visible; /* for IE */
  _zoom: 1; /* for IE */
}

While this works... it is not ideal to use hacks.

PIE: Easy Clearing Method

This older "Easy Clearing" method has the advantage of allowing positioned elements to hang outside the bounds of the container, at the expense of more tricky CSS.

This solution is quite old, but you can learn all about Easy Clearing on Position Is Everything: http://www.positioniseverything.net/easyclearing.html

Element using "clear" property

The quick and dirty solution (with some drawbacks) for when you’re quickly slapping something together:

<br style="clear: both" /> <!-- So dirty! -->

Drawbacks

• It's not responsive and thus may not provide the desired effect if layout styles change based upon media queries. A solution in pure CSS is more ideal.
• It adds html markup without necessarily adding any semantic value.
• It requires a inline definition and solution for each instance rather than a class reference to a single solution of a “clearfix” in the css and class references to it in the html.
• It makes code difficult to work with for others as they may have to write more hacks to work around it.
• In the future when you need/want to use another clearfix solution, you won't have to go back and remove every <br style="clear: both" /> tag littered around the markup.

A pure RESTful API should use the underlying protocol standard features:

1. For HTTP, the RESTful API should comply with existing HTTP standard headers. Adding a new HTTP header violates the REST principles. Do not re-invent the wheel, use all the standard features in HTTP/1.1 standards - including status response codes, headers, and so on. RESTFul web services should leverage and rely upon the HTTP standards.

2. RESTful services MUST be STATELESS. Any tricks, such as token based authentication that attempts to remember the state of previous REST requests on the server violates the REST principles. Again, this is a MUST; that is, if you web server saves any request/response context related information on the server in attempt to establish any sort of session on the server, then your web service is NOT Stateless. And if it is NOT stateless it is NOT RESTFul.

Bottom-line: For authentication/authorization purposes you should use HTTP standard authorization header. That is, you should add the HTTP authorization / authentication header in each subsequent request that needs to be authenticated. The REST API should follow the HTTP Authentication Scheme standards.The specifics of how this header should be formatted are defined in the RFC 2616 HTTP 1.1 standards – section 14.8 Authorization of RFC 2616, and in the RFC 2617 HTTP Authentication: Basic and Digest Access Authentication.

I have developed a RESTful service for the Cisco Prime Performance Manager application. Search Google for the REST API document that I wrote for that application for more details about RESTFul API compliance here. In that implementation, I have chosen to use HTTP "Basic" Authorization scheme. - check out version 1.5 or above of that REST API document, and search for authorization in the document.

Here's what I do:

curl https://raw.githubusercontent.com/creationix/nvm/v0.20.0/install.sh | bash
cd / && . ~/.nvm/nvm.sh && nvm install 0.10.35
. ~/.nvm/nvm.sh && nvm alias default 0.10.35

No Homebrew for this one.

nvm soon will support io.js, but not at time of posting: https://github.com/creationix/nvm/issues/590

Then install everything else, per-project, with a package.json and npm install.

Try to export the correct profile i.e. $ export AWS_PROFILE="default" If you only have a default profile make sure the keys are correct and rerun aws configure

A cookie is a object with key value pair to store information related to the customer. Main objective is to personalize the customer's experience.

An utility method can be created like

private Cookie createCookie(String cookieName, String cookieValue) {
    Cookie cookie = new Cookie(cookieName, cookieValue);
    cookie.setPath("/");
    cookie.setMaxAge(MAX_AGE_SECONDS);
    cookie.setHttpOnly(true);
    cookie.setSecure(true);
    return cookie;
}

If storing important information then we should alsways put setHttpOnly so that the cookie cannot be accessed/modified via javascript. setSecure is applicable if you are want cookies to be accessed only over https protocol.

using above utility method you can add cookies to response as

Cookie cookie = createCookie("name","value");
response.addCookie(cookie);

For your requirements it sounds like the bottom line will be to use Swing since it is slightly easier to get started with and not as tightly integrated to the native platform as SWT.

Swing usually is a safe bet.

The issue here is that ng-repeat creates its own scope, so when you do selected=$index it creates a new a selected property in that scope rather than altering the existing one. To fix this you have two options:

Change the selected property to a non-primitive (ie object or array, which makes javascript look up the prototype chain) then set a value on that:

$scope.selected = {value: 0};

<a ng-click="selected.value = $index">A{{$index}}</a>

See plunker

or

Use the $parent variable to access the correct property. Though less recommended as it increases coupling between scopes

<a ng-click="$parent.selected = $index">A{{$index}}</a>

See plunker

PhpMyAdmin has a Import wizard that lets you import a MSSQL file type too.

See http://dev.mysql.com/doc/refman/5.1/en/sql-mode.html for the types of DB scripts it supports.

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

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

The best way is to change any setting you want in your code.

Check out the below example:

using(WCFServiceClient client = new WCFServiceClient ())
{ 
    client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 1, 30);
}

Numpty here used SQL authentication

instead of Windows (correct)

when adding the login to SQL Server, which also gives you this error if you are using Windows auth.

Let's recap this (for 2019+).

Argument: Values such as true, false, null are valid JSON (?)

FACT: These primitive values are JSON-parsable but they are not well-formed JSON structures. JSON specification indicates JSON is built on on two structures: A collection of name/value pair (object) or an ordered list of values (array).

Argument: Exception handling shouldn't be used to do something expected.
(This is a comment that has 25+ upvotes!)

FACT: No! It's definitely legal to use try/catch, especially in a case like this. Otherwise, you'd need to do lots of string analysis stuff such as tokenizing / regex operations; which would have terrible performance.

hasJsonStructure()

This is useful if your goal is to check if some data/text has proper JSON interchange format.

function hasJsonStructure(str) {
    if (typeof str !== 'string') return false;
    try {
        const result = JSON.parse(str);
        const type = Object.prototype.toString.call(result);
        return type === '[object Object]' 
            || type === '[object Array]';
    } catch (err) {
        return false;
    }
}

Usage:

hasJsonStructure('true')             // —» false
hasJsonStructure('{"x":true}')       // —» true
hasJsonStructure('[1, false, null]') // —» true

safeJsonParse()

And this is useful if you want to be careful when parsing some data to a JavaScript value.

function safeJsonParse(str) {
    try {
        return [null, JSON.parse(str)];
    } catch (err) {
        return [err];
    }
}

Usage:

const [err, result] = safeJsonParse('[Invalid JSON}');
if (err) {
    console.log('Failed to parse JSON: ' + err.message);
} else {
    console.log(result);
}

Ok, I think I got it.

The client is the docker command installed into OS X.

The host is the Boot2Docker VM.

The daemon is a background service running inside Boot2Docker.

This variable tells the client how to connect to the daemon.

When starting Boot2Docker, the terminal window that pops up already has DOCKER_HOST set, so that's why docker commands work. However, to run Docker commands in other terminal windows, you need to set this variable in those windows.

Failing to set it gives a message like this:

$ docker run hello-world
2014/08/11 11:41:42 Post http:///var/run/docker.sock/v1.13/containers/create: 
dial unix /var/run/docker.sock: no such file or directory

One way to fix that would be to simply do this:

$ export DOCKER_HOST=tcp://192.168.59.103:2375

But, as pointed out by others, it's better to do this:

$ $(boot2docker shellinit)
$ docker run hello-world
Hello from Docker. [...]

To spell out this possibly non-intuitive Bash command, running boot2docker shellinit returns a set of Bash commands that set environment variables:

export DOCKER_HOST=tcp://192.168.59.103:2376
export DOCKER_CERT_PATH=/Users/ddavison/.boot2docker/certs/boot2docker-vm
export DOCKER_TLS_VERIFY=1

Hence running $(boot2docker shellinit) generates those commands, and then runs them.

I was having a very similar problem, and it turned out to be quite simple; my client wasn't including a Jackson dependency, even though the code all compiled correctly, the auto-magic converters for JSON weren't being included. See this RestTemplate-related solution.

In short, I added a Jackson dependency to my pom.xml and it just worked:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.5.1</version>
</dependency>

I experienced this issue when working with PostgreSQL on Ubuntu 18.04.

I checked my PostgreSQL status and realized that it was running fine using:

sudo systemctl status postgresql

I also tried restarting the PotgreSQL server on the machine using:

sudo systemctl restart postgresql

but the issue persisted:

psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

Following Noushad' answer I did the following:

List all the Postgres clusters running on your device:

pg_lsclusters

this gave me this output in red colour, showing that they were all down and the status also showed down:

Ver Cluster Port Status Owner    Data directory              Log file
10  main    5432 down   postgres /var/lib/postgresql/10/main /var/log/postgresql/postgresql-10-main.log
11  main    5433 down   postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
12  main    5434 down   postgres /var/lib/postgresql/12/main /var/log/postgresql/postgresql-12-main.log

Restart the pg_ctlcluster for one of the server clusters. For me I restarted PG 10:

sudo pg_ctlcluster 10 main start

It however threw the error below, and the same error occurred when I tried restarting other PG clusters:

Job for [email protected] failed because the service did not take the steps required by its unit configuration.
See "systemctl status [email protected]" and "journalctl -xe" for details.

Check the log for errors, in this case mine is PG 10:

sudo nano /var/log/postgresql/postgresql-10-main.log

I saw the following error:

2020-09-29 02:27:06.445 WAT [25041] FATAL:  data directory "/var/lib/postgresql/10/main" has group or world access
2020-09-29 02:27:06.445 WAT [25041] DETAIL:  Permissions should be u=rwx (0700).
pg_ctl: could not start server
Examine the log output.

This was caused because I made changes to the file permissions for the PostgreSQL data directory.

I fixed it by running the command below. I ran the command for the 3 PG clusters on my machine:

sudo chmod -R 0700 /var/lib/postgresql/10/main
sudo chmod -R 0700 /var/lib/postgresql/11/main
sudo chmod -R 0700 /var/lib/postgresql/12/main

Afterwhich I restarted each of the PG clusters:

sudo pg_ctlcluster 10 main start
sudo pg_ctlcluster 11 main start
sudo pg_ctlcluster 12 main start

And then finally I checked the health of clusters again:

pg_lsclusters

this time around everything was fine again as the status showed online:

Ver Cluster Port Status Owner    Data directory              Log file
10  main    5432 online postgres /var/lib/postgresql/10/main /var/log/postgresql/postgresql-10-main.log
11  main    5433 online postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
12  main    5434 online postgres /var/lib/postgresql/12/main /var/log/postgresql/postgresql-12-main.log

That's all.

I hope this helps

Where are you configuring your authenticated URL pattern(s)? I only see one uri in your code.

Do you have multiple configure(HttpSecurity) methods or just one? It looks like you need all your URIs in the one method.

I have a site which requires authentication to access everything so I want to protect /*. However in order to authenticate I obviously want to not protect /login. I also have static assets I'd like to allow access to (so I can make the login page pretty) and a healthcheck page that shouldn't require auth.

In addition I have a resource, /admin, which requires higher privledges than the rest of the site.

The following is working for me.

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.authorizeRequests()
        .antMatchers("/login**").permitAll()
        .antMatchers("/healthcheck**").permitAll()
        .antMatchers("/static/**").permitAll()
        .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")
        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .and()
            .formLogin().loginPage("/login").failureUrl("/login?error")
                .usernameParameter("username").passwordParameter("password")
        .and()
            .logout().logoutSuccessUrl("/login?logout")
        .and()
            .exceptionHandling().accessDeniedPage("/403")
        .and()
            .csrf();

}

NOTE: This is a first match wins so you may need to play with the order. For example, I originally had /** first:

        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .antMatchers("/login**").permitAll()
        .antMatchers("/healthcheck**").permitAll()

Which caused the site to continually redirect all requests for /login back to /login. Likewise I had /admin/** last:

        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")

Which resulted in my unprivledged test user "guest" having access to the admin interface (yikes!)

Use isinstance:

if isinstance(e, list):

If you want to check that an object is a list or a tuple, pass several classes to isinstance:

if isinstance(e, (list, tuple)):

None of the above helped me completely. Although Oventoaster made me think. I had a couple of adb on my system. Removed them almost all.

I am running android studio on ubuntu 14.04 64 bit.

So I checked manually /home/xxxxx/Android/Sdk/platform-tools/adb

where xxxxx was my linux username

this gave

Since you are using Visual Studio 11 Beta, you will want to use the latest and greatest. The new Web API contains classes for this.

See HttpClient: http://wcf.codeplex.com/wikipage?title=WCF%20HTTP

in my context, he would push the sticky toolbar off the screen, or enter next to a fab button with absolute.

using the nearest solved.

const element = this.element.nativeElement;
const table = element.querySelector('.table-container');
table.scrollIntoView({

});

In React Router version 5.0.1 and above, you can use:

<Link to="route" target="_blank" onClick={(event) => {event.preventDefault(); window.open(this.makeHref("route"));}} />

The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.

You can add a multi-line label with the following:

JLabel label = new JLabel("My label");

label.setText("<html>This is a<br>multline label!<br> Try it yourself!</html>");

From here, simply add the label to the frame using the add() method, and you're all set!

If you talk about Activity, AppcompactActivity, ActionBarActivity etc etc..

We need to talk about Base classes which they are extending, First we have to understand the hierarchy of super classes.

All the things are started from Context which is super class for all these classes.

Context is an abstract class whose implementation is provided by the Android system. It allows access to application-specific resources and classes, as well as up-calls for application-level operations such as launching activities, broadcasting and receiving intents, etc

Context is followed by or extended by ContextWrapper

The ContextWrapper is a class which extend Context class that simply delegates all of its calls to another Context. Can be subclassed to modify behavior without changing the original Context.

Now we Reach to Activity

The Activity is a class which extends ContextThemeWrapper that is a single, focused thing that the user can do. Almost all activities interact with the user, so the Activity class takes care of creating a window for you

Below Classes are restricted to extend but they are extended by their descender internally and provide support for specific Api

The SupportActivity is a class which extends Activity that is a Base class for composing together compatibility functionality

The BaseFragmentActivityApi14 is a class which extends SupportActivity that is a Base class It is restricted class but it is extend by BaseFragmentActivityApi16 to support the functionality of V14

The BaseFragmentActivityApi16 is a class which extends BaseFragmentActivityApi14 that is a Base class for {@code FragmentActivity} to be able to use v16 APIs. But it is also restricted class but it is extend by FragmentActivity to support the functionality of V16.

now FragmentActivty

The FragmentActivity is a class which extends BaseFragmentActivityApi16 and that wants to use the support-based Fragment and Loader APIs.

When using this class as opposed to new platform's built-in fragment and loader support, you must use the getSupportFragmentManager() and getSupportLoaderManager() methods respectively to access those features.

ActionBarActivity is part of the Support Library. Support libraries are used to deliver newer features on older platforms. For example the ActionBar was introduced in API 11 and is part of the Activity by default (depending on the theme actually). In contrast there is no ActionBar on the older platforms. So the support library adds a child class of Activity (ActionBarActivity) that provides the ActionBar's functionality and ui

In 2015 ActionBarActivity is deprecated in revision 22.1.0 of the Support Library. AppCompatActivity should be used instead.

The AppcompactActivity is a class which extends FragmentActivity that is Base class for activities that use the support library action bar features.

You can add an ActionBar to your activity when running on API level 7 or higher by extending this class for your activity and setting the activity theme to Theme.AppCompat or a similar theme

I refer these two one,two

You can simply use matches method of String class.

boolean result = someString.matches("stores.*store.*product.*");

Assuming the file exists and you just need to update the timestamp.

type test.c > test.c.bkp && type test.c.bkp > test.c && del test.c.bkp

The following would do but only will replace one occurence:

"string".replace('/', 'ForwardSlash');

For a global replacement, or if you prefer regular expressions, you just have to escape the slash:

"string".replace(/\//g, 'ForwardSlash');

This is the technique I'd use and I don't see it here yet. The link (posted by Saajid Ismail ) that inspires this solution is http://weblogs.asp.net/dfindley/archive/2009/05/31/asp-net-mvc-multiple-buttons-in-the-same-form.aspx). It adapts Dylan Beattie's answer to do localization without any problems.

In the View:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<button name="button" value="send"><%: Resources.Messages.Send %></button>
<button name="button" value="cancel"><%: Resources.Messages.Cancel %></button>
<% Html.EndForm(); %>

In the Controller:

public class MyController : Controller 
{
    public ActionResult MyAction(string button)
    {
         switch(button)
         {
             case "send":
                 this.DoSend();
                 break;
             case "cancel":
                 this.DoCancel();
                 break;
         }
    }
}

On performance you keep focusing on select.
Shared does not block reads.
Shared lock blocks update.
If you have hundreds of shared locks it is going to take an update a while to get an exclusive lock as it must wait for shared locks to clear.

By default a select (read) takes a shared lock.
Shared (S) locks allow concurrent transactions to read (SELECT) a resource.
A shared lock as no effect on other selects (1 or a 1000).

The difference is how the nolock versus shared lock effects update or insert operation.

No other transactions can modify the data while shared (S) locks exist on the resource.

A shared lock blocks an update!
But nolock does not block an update.

This can have huge impacts on performance of updates. It also impact inserts.

Dirty read (nolock) just sounds dirty. You are never going to get partial data. If an update is changing John to Sally you are never going to get Jolly.

I use shared locks a lot for concurrency. Data is stale as soon as it is read. A read of John that changes to Sally the next millisecond is stale data. A read of Sally that gets rolled back John the next millisecond is stale data. That is on the millisecond level. I have a dataloader that take 20 hours to run if users are taking shared locks and 4 hours to run is users are taking no lock. Shared locks in this case cause data to be 16 hours stale.

Don't use nolocks wrong. But they do have a place. If you are going to cut a check when a byte is set to 1 and then set it to 2 when the check is cut - not a time for a nolock.

After visiting this question and noting the initial concerns of the chosen solution, I figured I'd contribute this one for those not using Java 7 which uses FileUtils instead of IOUtils from Apache Commons. The advantage here is that the readFileToString and the writeStringToFile handle the issue of closing the files for you automatically. (writeStringToFile doesn't document it but you can read the source). Hopefully this recipe simplifies things for anyone new coming to this problem.

  try {
     String content = FileUtils.readFileToString(new File("InputFile"), "UTF-8");
     content = content.replaceAll("toReplace", "replacementString");
     File tempFile = new File("OutputFile");
     FileUtils.writeStringToFile(tempFile, content, "UTF-8");
  } catch (IOException e) {
     //Simple exception handling, replace with what's necessary for your use case!
     throw new RuntimeException("Generating file failed", e);
  }

You could also have embed all of your template views into your main html file. For Example:

<body ng-app="testApp">
  <h1>Test App</h1>
  <div ng-view></div>
  <script type = "text/ng-template" id = "index.html">
    <h1>Index Page</h1>
    <p>{{message}}</p>
  </script>
  <script type = "text/ng-template" id = "home.html">
    <h1>Home Page</h1>
    <p>{{message}}</p>
  </script>
</body>

This way if each template requires a different controller then you can still use the angular-router. See this plunk for a working example http://plnkr.co/edit/9X0fT0Q9MlXtHVVQLhgr?p=preview

This way once the application is sent from the server to your client, it is completely self contained assuming that it doesn't need to make any data requests, etc.

Related to this question, I just figured out why my vhost was giving me that 403.

I had tested ALL possibilities on this question and others without luck. It almost drives me mad.

I am setting up a server with releases deployment similar to Capistrano way through symlinks and when I tried to access the DocRoot folder (which is now a symlink to current release folder) it gave me the 403.

My vhost is:

DocumentRoot /var/www/site.com/html
<Directory /var/www/site.com/html>
        AllowOverride All
        Options +FollowSymLinks
        Require all granted
</Directory>

and my main httpd.conf file was (default Apache 2.4 install):

DocumentRoot "/var/www"
<Directory "/var/www">
    Options -Indexes -FollowSymLinks -Includes
(...)

It turns out that the main Options definition was taking precedence over my vhosts fiel (for me that is counter intuitive). So I've changed it to:

DocumentRoot "/var/www"
<Directory "/var/www">
    Options -Indexes +FollowSymLinks -Includes
(...)

and Eureka! (note the plus sign before FollowSymLinks in MAIN httpd.conf file. Hope this help some other lost soul.

To convert a pandas dataframe (df) to a numpy ndarray, use this code:

df.values

array([[nan, 0.2, nan],
       [nan, nan, 0.5],
       [nan, 0.2, 0.5],
       [0.1, 0.2, nan],
       [0.1, 0.2, 0.5],
       [0.1, nan, 0.5],
       [0.1, nan, nan]])

Every call to the Iterator.next() moves the iterator to the next element. If you want to use the current element in more than one statement or expression, you have to store it in a local variable. Or even better, why don't you simply use a for-each loop?

for (String key : map.keySet()) {
    System.out.println(key + ":" + map.get(key));
}

Moreover, loop over the entrySet is faster, because you don't query the map twice for each key. Also Map.Entry implementations usually implement the toString() method, so you don't have to print the key-value pair manually.

for (Entry<String, Integer> entry : map.entrySet()) {
    System.out.println(entry);
}

Assuming t1 is the folder with files in it, and t2 is the empty directory. What you want is something like this:

sudo cp -R t1/* t2/

Bear in mind, for the first example, t1 and t2 have to be the full paths, or relative paths (based on where you are). If you want, you can navigate to the empty folder (t2) and do this:

sudo cp -R t1/* ./

Or you can navigate to the folder with files (t1) and do this:

sudo cp -R ./* t2/

Note: The * sign (or wildcard) stands for all files and folders. The -R flag means recursively (everything inside everything).

To simply combine them you can place them all together like this:

=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A2,"_AB","_"),"_CD","_"),"_EF","_"),"_40K",""),"_60K",""),"_S_","_"),"_","-")

(note that this may pass the older Excel limit of 7 nested statements. I'm testing in Excel 2010

Another way to do it is by utilizing Left and Right functions.

This assumes that the changing data on the end is always present and is 8 characters long

=SUBSTITUTE(LEFT(A2,LEN(A2)-8),"_","-")

This will achieve the same resulting string

If the string doesn't always end with 8 characters that you want to strip off you can search for the "_S" and get the current location. Try this:

=SUBSTITUTE(LEFT(A2,FIND("_S",A2,1)),"_","-")

Your Ubuntu definitely has a sufficiently recent version of g++. The flag to use is -std=c++0x.

I was having the same problem. It seems that passing Me.ComboBox1.Value as an argument for the Vlookup function is causing the issue. What I did was assign this value to a double and then put it into the Vlookup function.

Dim x As Double
x = Me.ComboBox1.Value
Me.TextBox1.Value = Application.WorksheetFunction.VLookup(x, Worksheets("Sheet3").Range("Names"), 2, False) 

Or, for a shorter method, you can just convert the type within the Vlookup function using Cdbl(<Value>).

So it would end up being

Me.TextBox1.Value = Application.WorksheetFunction.VLookup(Cdbl(Me.ComboBox1.Value), Worksheets("Sheet3").Range("Names"), 2, False) 

Strange as it may sound, it works for me.

Hope this helps.

I found my I had built my object incorrectly. I used http://json2csharp.com/ to generate me my object class from the JSON. Once I had the correct Oject I was able to cast without issue. Norbit, Noob mistake. Thought I'd add it in case you have the same issue.

For some unexplained reason this solution doesn't work for me (maybe some incompatibility of types), so I came up with a solution for myself:

HttpResponseMessage response = await client.GetAsync("api/yourcustomobjects");
if (response.IsSuccessStatusCode)
{
    var data = await response.Content.ReadAsStringAsync();
    var product = JsonConvert.DeserializeObject<Product>(data);
}

This way my content is parsed into a JSON string and then I convert it to my object.

In this simple way

char str [10] = "IAmCute";
printf ("%c",str[4]);

There is a vcvars32.bat in your Visual Studio installation directory. You can add call cmd.exe at the end of that batch program and launch it. From that shell you can use CMake or cmake-gui and cl.exe would be known to CMake.

Best Way to Refresh Adapter/ListView on Android

Not only calling notifyDataSetChanged() will refresh the ListView data, setAdapter() must be called before to load the information correctly:

  listView.setAdapter(adapter);
  adapter.notifyDataSetChanged();

You can do it right in your XML file:

android:onClick="@drawable/ic_action_search"

-z string True if the string is null (an empty string)

For my layout, I didn't want a hack (no width increasing, no on click with auto and then coming to original). It broke my existing layout. I just wanted it to work normally like other browsers.

I found this to be exactly like that :-

A category for going getting away from the NSString description

In general, it is desirable to avoid arbitrary string comparisons throughout your code. It is better to update the strings in one place and hide the magic string from your app. I provide a category on UIDevice for that purpose.

For my specific needs I need to know which device I am using without the need to know specifics about networking capability that can be easily retrieved in other ways. So you will find a coarser grained enum than the ever growing list of devices.

Updating is a matter of adding the device to the enum and the lookup table.

I haven't tried it but if you put a div in your table cell set so that it will have scrollbars if needed, then you could insert in there, with a fixed height on the div and it should keep your table row to a fixed height.

function validate(){    
    var re = /^[A-Za-z]+$/;
    if(re.test(document.getElementById("textboxID").value))
       alert('Valid Name.');
    else
       alert('Invalid Name.');      
}

I think the OP's problem was that he wants to do BOTH of the following:

• Pass a parameter which may contain spaces
• Test whether the parameter is missing

As several posters have mentioned, to pass a parameter containing spaces, you must surround the actual parameter value with double quotes.

To test whether a parameter is missing, the method I always learned was:

if "%1" == ""

However, if the actual parameter is quoted (as it must be if the value contains spaces), this becomes

if ""actual parameter value"" == ""

which causes the "unexpected" error. If you instead use

if %1 == ""

then the error no longer occurs for quoted values. But in that case, the test no longer works when the value is missing -- it becomes

if  == ""

To fix this, use any other characters (except ones with special meaning to DOS) instead of quotes in the test:

if [%1] == []
if .%1. == ..
if abc%1xyz == abcxyz

Your model is null because the way you're supplying the inputs to your form means the model binder has no way to distinguish between the elements. Right now, this code:

@foreach (var planVM in Model)
{
    @Html.Partial("_partialView", planVM)
}

is not supplying any kind of index to those items. So it would repeatedly generate HTML output like this:

<input type="hidden" name="yourmodelprefix.PlanID" />
<input type="hidden" name="yourmodelprefix.CurrentPlan" />
<input type="checkbox" name="yourmodelprefix.ShouldCompare" />

However, as you're wanting to bind to a collection, you need your form elements to be named with an index, such as:

<input type="hidden" name="yourmodelprefix[0].PlanID" />
<input type="hidden" name="yourmodelprefix[0].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[0].ShouldCompare" />
<input type="hidden" name="yourmodelprefix[1].PlanID" />
<input type="hidden" name="yourmodelprefix[1].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[1].ShouldCompare" />

That index is what enables the model binder to associate the separate pieces of data, allowing it to construct the correct model. So here's what I'd suggest you do to fix it. Rather than looping over your collection, using a partial view, leverage the power of templates instead. Here's the steps you'd need to follow:

1. Create an EditorTemplates folder inside your view's current folder (e.g. if your view is Home\Index.cshtml, create the folder Home\EditorTemplates).
2. Create a strongly-typed view in that directory with the name that matches your model. In your case that would be PlanCompareViewModel.cshtml.

Now, everything you have in your partial view wants to go in that template:

@model PlanCompareViewModel
<div>
    @Html.HiddenFor(p => p.PlanID)
    @Html.HiddenFor(p => p.CurrentPlan)
    @Html.CheckBoxFor(p => p.ShouldCompare)
   <input type="submit" value="Compare"/>
</div>

Finally, your parent view is simplified to this:

@model IEnumerable<PlanCompareViewModel>
@using (Html.BeginForm("ComparePlans", "Plans", FormMethod.Post, new { id = "compareForm" }))
{
<div>
    @Html.EditorForModel()
</div>
}

DisplayTemplates and EditorTemplates are smart enough to know when they are handling collections. That means they will automatically generate the correct names, including indices, for your form elements so that you can correctly model bind to a collection.

%~dp0 - return the path from where script executed

But, important to know also below one:

%CD% - return the current path in runtime, for example if you get into other folders using "cd folder1", and then "cd folder2", it will return the full path until folder2 and not the original path where script located

function check (list){
    var foundRepeatingValue = false;
    var newList = [];
    for(i=0;i<list.length;i++){
        var thisValue = list[i];
        if(i>0){
            if(newList.indexOf(thisValue)>-1){
                foundRepeatingValue = true;
                console.log("getting repeated");
                return true;
            }
       } newList.push(thisValue);
    } return false;
}

var list1 = ["dse","dfg","dse"];
check(list1);

Output:

getting repeated
true

For renaming recursively I use the following commands:

find -iname \*.* | rename -v "s/ /-/g"

this.Controls.Find(name, searchAllChildren) doesn't find ToolStripItem because ToolStripItem is not a Control

  using SWF = System.Windows.Forms;
  using NUF = NUnit.Framework;
  namespace workshop.findControlTest {
     [NUF.TestFixture]
     public class FormTest {
        [NUF.Test]public void Find_menu() {
           // == prepare ==
           var fileTool = new SWF.ToolStripMenuItem();
           fileTool.Name = "fileTool";
           fileTool.Text = "File";

           var menuStrip = new SWF.MenuStrip();
           menuStrip.Items.Add(fileTool);

           var form = new SWF.Form();
           form.Controls.Add(menuStrip);

           // == execute ==
           var ctrl = form.Controls.Find("fileTool", true);

           // == not found! ==
           NUF.Assert.That(ctrl.Length, NUF.Is.EqualTo(0)); 
        }
     }
  }

My issue came down to a silly mistake on my part. As I had quickly one day dropped my proxies into a windows *.bat file (http_proxy, https_proxy, and ftp_proxy), I forgot to escape the special characters for the url-encoded domain\user (%5C) and password having the question mark '?' (%3F). That is to say, once you have the encoded command, don't forget to escape the '%' in the bat file command.

I changed

set http_proxy=http://domain%5Cuser:password%3F@myproxy:8080

to

set http_proxy=http://domain%%5Cuser:password%%3F@myproxy:8080

Maybe it's an edge case but hopefully it helps someone.

You can also change the pop-up options themselves, to be more convenient for your normal use. Summary:

1. Run the SQL Management Studio Express 2008
2. Click the Tools -> Options

3. Select SQL Server Object Explorer . Now you should be able to see the options

   • Value for Edit Top Rows Command
   • Value for Select Top Rows Command

4. Give the Values 0 here to select/ Edit all the Records

Full Instructions with screenshots are here: http://m-elshazly.blogspot.com/2011/01/sql-server-2008-change-edit-top-200.html

The issue can also be due to lack of hard drive space. The installation will succeed but on startup, oracle won't be able to create the required files and will fail with the same above error message.

var newArray = oldArray.filter(function(v){return v!==''});

There is now a an approach to do this, using Doctrine's Criteria.

A full example can be seen in How to use a findBy method with comparative criteria, but a brief answer follows.

use \Doctrine\Common\Collections\Criteria;

// Add a not equals parameter to your criteria
$criteria = new Criteria();
$criteria->where(Criteria::expr()->neq('prize', 200));

// Find all from the repository matching your criteria
$result = $entityRepository->matching($criteria);

Just visit the plugins folder and delete the last plugin you uploaded and should do the trick.

Under use strict, say:

(my $new = $original) =~ s/foo/bar/;

instead.

If you use SQL Server 2008 or higher, use table valued parameters; for example:

CREATE PROCEDURE [dbo].[GetAccounts](@accountIds nvarchar)
AS
BEGIN
    SELECT * 
    FROM accountsTable 
    WHERE accountId IN (select * from @accountIds)
END

CREATE TYPE intListTableType AS TABLE (n int NOT NULL)

DECLARE @tvp intListTableType 

-- inserts each id to one row in the tvp table    
INSERT @tvp(n) VALUES (16509),(16685),(46173),(42925),(46167),(5511)

EXEC GetAccounts @tvp

I have simply pasted the following to the top of my bash scripts:

#!/usr/bin/env bash -e

declare script=$(basename "$0")
declare dirname=$(dirname "$0")
declare scriptDir
if [[ $(uname) == 'Linux' ]];then
    # use readlink -f
    scriptDir=$(readlink -f "$dirname")
else
    # can't use readlink -f, do a pwd -P in the script directory and then switch back
    if [[ "$dirname" = '.' ]];then
        # don't change directory, we are already inside
        scriptDir=$(pwd -P)
    else
        # switch to the directory and then switch back
        pwd=$(pwd)
        cd "$dirname"
        scriptDir=$(pwd -P)
        cd "$pwd"
    fi
fi

And removed all instances of readlink -f. $scriptDir and $script then will be available for the rest of the script.

While this does not follow all symlinks, it works on all systems and appears to be good enough for most use cases, it switches the directory into the containing folder, and then it does a pwd -P to get the real path of that directory, and then finally switch back to the original.

This should do it:

UPDATE ProductReviews
SET    ProductReviews.status = '0'
FROM   ProductReviews
       INNER JOIN products
         ON ProductReviews.pid = products.id
WHERE  ProductReviews.id = '17190'
       AND products.shopkeeper = '89137'

There are several ways of exploiting this class. You can call either syncGetSystemCpuUsage or syncGetProcessCpuUsage but each is blocking the calling thread. Since a common issue is to monitor the total CPU usage and the CPU use of the current process at the same time, I have designed a class computing both of them. That class contains a dedicated thread. The output management is implementation specific and you need to code your own.

The class can be customized by a few means. The constant CPU_WINDOW defines the depth of a read, i.e. the number of milliseconds between readings and computing of the corresponding CPU load. CPU_REFRESH_RATE is the time between each CPU load measurement. Do not set CPU_REFRESH_RATE to 0 because it will suspend the thread after the first read.

Step 1: You have to add the line: default-storage-engine = InnoDB under the [mysqld] section of your mysql config file (my.cnf or my.ini depending on your OS) and restart the mysqld service.

Step 2: Now when you create the table you will see the type of table is: InnoDB

Step 3: Create both Parent and Child table. Now open the Child table and select the column U like to have the Foreign Key: Select the Index Key from Action Label as shown below.

Step 4: Now open the Relation View in the same child table from bottom near the Print View as shown below.

Step 5: Select the column U like to have the Foreign key as Select the Parent column from the drop down. dbName.TableName.ColumnName

Select appropriate Values for ON DELETE and ON UPDATE

"this" is also useful when calling one constructor from another:

public class MyClass {
    public MyClass(String foo) {
        this(foo, null);
    }
    public MyClass(String foo, String bar) {
        ...
    }
}

First of all, public static non-final fields are evil. Spring does not allow injecting to such fields for a reason.

Your workaround is valid, you don't even need getter/setter, private field is enough. On the other hand try this:

@Value("${my.name}")
public void setPrivateName(String privateName) {
    Sample.name = privateName;
}  

(works with @Autowired/@Resource). But to give you some constructive advice: Create a second class with private field and getter instead of public static field.

List<String> al=new ArrayList<string>();
al.add("One");
al.add("Two");
al.add("Three");

for(String al1:al) //for each construct
{
System.out.println(al1);
}

O/p will be

One
Two
Three

My guess is that you're trying to squeeze a number greater than 99999.99 into your decimal fields. Changing it to (8,3) isn't going to do anything if it's greater than 99999.999 - you need to increase the number of digits before the decimal. You can do this by increasing the precision (which is the total number of digits before and after the decimal). You can leave the scale the same unless you need to alter how many decimal places to store. Try decimal(9,2) or decimal(10,2) or whatever.

You can test this by commenting out the insert #temp and see what numbers the select statement is giving you and see if they are bigger than your column can handle.

I've got a YouTube video on this.

Short answer: Use mock when you're passing in the thing that you want mocked, and patch if you're not. Of the two, mock is strongly preferred because it means you're writing code with proper dependency injection.

Silly example:

# Use a mock to test this.
my_custom_tweeter(twitter_api, sentence):
    sentence.replace('cks','x')   # We're cool and hip.
    twitter_api.send(sentence)

# Use a patch to mock out twitter_api. You have to patch the Twitter() module/class 
# and have it return a mock. Much uglier, but sometimes necessary.
my_badly_written_tweeter(sentence):
    twitter_api = Twitter(user="XXX", password="YYY")
    sentence.replace('cks','x') 
    twitter_api.send(sentence)

I had similar question however mine involved a column Convert(date,mydatetime). I had to alter the best answer as follows:

Select
     count(created_date) as counted_leads,
     Convert(date,created_date) as count_date 
from table
group by Convert(date,created_date)

For powershell in Windows, you can add relative path + filename to --output flag:

curl -L  http://github.com/GorvGoyl/Notion-Boost-browser-extension/archive/master.zip --output build_firefox/master-repo.zip

here build_firefox is relative folder.

i suggest PDFMerger from github.com, so easy like ::

include 'PDFMerger.php';

$pdf = new PDFMerger;

$pdf->addPDF('samplepdfs/one.pdf', '1, 3, 4')
    ->addPDF('samplepdfs/two.pdf', '1-2')
    ->addPDF('samplepdfs/three.pdf', 'all')
    ->merge('file', 'samplepdfs/TEST2.pdf'); // REPLACE 'file' WITH 'browser', 'download', 'string', or 'file' for output options

In addition to victor hugo's answer it is possible to get all known character references legal in an XSLT file, like this:

<!DOCTYPE stylesheet [
  <!ENTITY % w3centities-f PUBLIC "-//W3C//ENTITIES Combined Set//EN//XML"
      "http://www.w3.org/2003/entities/2007/w3centities-f.ent">
  %w3centities-f;
]>
...
<xsl:text>&amp; &nbsp; &ndash;</xsl:text>

There is also certain difference in the result of this approach as compared to <xsl:text disable-output-escaping="yes"> one. The latter is going to produce string literals like   for all kinds of output, even for <xsl:output method="text">, and this may happen to be different from what you might wish... On the contrary, getting entities defined for XSLT template via <!DOCTYPE ... <!ENTITY ... will always produce output consistent with your xsl:output settings.

And when including all character references, it may be wise to use a local entity resolver to keep the XSLT engine from fetching character entity definitions from the Internet. JAXP or explicit Xalan-J users may need a patch for Xalan-J to use the resolver correctly. See my blog XSLT, entities, Java, Xalan... for patch download and comments.

I would check the "End of File" flag:

If temp_rst1.EOF Or temp_rst2.EOF Then MsgBox "null"

Today, I would recommend using Task.CompletedTask to accomplish this.

Pre .net 4.6:

Using Task.FromResult(0) or Task.FromResult<object>(null) will incur less overhead than creating a Task with a no-op expression. When creating a Task with a result pre-determined, there is no scheduling overhead involved.

AdBlockers usually have some rules, i.e. they match the URIs against some type of expression (sometimes they also match the DOM against expressions, not that this matters in this case).

Having rules and expressions that just operate on a tiny bit of text (the URI) is prone to create some false-positives...

Besides instructing your users to disable their extensions (at least on your site) you can also get the extension and test which of the rules/expressions blocked your stuff, provided the extension provides enough details about that. Once you identified the culprit, you can either try to avoid triggering the rule by using different URIs, report the rule as incorrect or overly-broad to the team that created it, or both. Check the docs for a particular add-on on how to do that.

For example, AdBlock Plus has a Blockable items view that shows all blocked items on a page and the rules that triggered the block. And those items also including XHR requests.

try this,

package example.txtRead;

import java.io.BufferedReader;
import java.io.ByteArrayOutputStream;

    int j=0;
    private StringTokenizer tokenizer;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        wordss = new Vector<String>();
        TextView helloTxt = (TextView)findViewById(R.id.hellotxt);
        helloTxt.setText(readTxt());
 }

    private String readTxt(){

     InputStream inputStream = getResources().openRawResource(R.raw.toc);
//     InputStream inputStream = getResources().openRawResource(R.raw.internals);
     System.out.println(inputStream);
     ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

     int i;
  try {
   i = inputStream.read();
   while (i != -1)
      {
       byteArrayOutputStream.write(i);
       i = inputStream.read();
      }
      inputStream.close();
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

     return byteArrayOutputStream.toString();
    }
}

With TypeScript use window.location.href as window.location is technically an object containing:

Properties
hash 
host 
hostname
href    <--- you need this
pathname (relative to the host)
port 
protocol 
search 

Setting window.location will produce a type error, while window.location.href is of type string.

To avoid double encoding issue described in taras.roshko's answer and to keep possibility to easily work with query parameters, you can use uriBuilder.Uri.ParseQueryString() instead of HttpUtility.ParseQueryString().

Another option to avoid nesting two different environments (like multicols and enumerate).

The environment called tasks from the package with the same name seems to me very easy to customize thanks to a variety of options (pdf guide here).

This code:

\documentclass{article}
\usepackage{tasks}

%\settasks{style=itemize}

\begin{document}
Text text text text text text text text text text text text 
text text text text text text text text text text text text 
text text text text text text text text text text text text.

\begin{tasks}(2)
\task[*] a
\task[*] b
\task[*] c
\task[*] d
\task[*] e
\task[*] f
\end{tasks}    

Text text text text text text text text text text text text 
text text text text text text text text text text text text 
text text text text text text text text text text text text.
\end{document}

produces this output

The package tasks was updated in August 2020 and it was originally created specifically for horizontally columned lists (see the screenshot just above here), the motivations behind this are resumed in the guide. If such arrangement of the items/tasks is acceptable, then this may be a good choice since it keeps - IMHO - the code tidy and flexible.

BASEPAIRS = { "T": "A", "A": "T", "G": "C", "C": "G" } What would you use?

Maybe:

static const char basepairs[] = "ATAGCG";
// lookup:
if (const char* p = strchr(basepairs, c))
    // use p[1]

;-)

Using \n in sed is non-portable. The portable way to do what you want with sed is:

sed 's/:/\
/g' ~/Desktop/myfile.txt

but in reality this isn't a job for sed anyway, it's the job tr was created to do:

tr ':' '
' < ~/Desktop/myfile.txt

From the documentation:

We can add to a list in many ways:

assert [1,2] + 3 + [4,5] + 6 == [1, 2, 3, 4, 5, 6]
assert [1,2].plus(3).plus([4,5]).plus(6) == [1, 2, 3, 4, 5, 6]
    //equivalent method for +
def a= [1,2,3]; a += 4; a += [5,6]; assert a == [1,2,3,4,5,6]
assert [1, *[222, 333], 456] == [1, 222, 333, 456]
assert [ *[1,2,3] ] == [1,2,3]
assert [ 1, [2,3,[4,5],6], 7, [8,9] ].flatten() == [1, 2, 3, 4, 5, 6, 7, 8, 9]

def list= [1,2]
list.add(3) //alternative method name
list.addAll([5,4]) //alternative method name
assert list == [1,2,3,5,4]

list= [1,2]
list.add(1,3) //add 3 just before index 1
assert list == [1,3,2]
list.addAll(2,[5,4]) //add [5,4] just before index 2
assert list == [1,3,5,4,2]

list = ['a', 'b', 'z', 'e', 'u', 'v', 'g']
list[8] = 'x'
assert list == ['a', 'b', 'z', 'e', 'u', 'v', 'g', null, 'x']

You can also do:

def myNewList = myList << "fifth"

I think the problem can be because of the NAT. Normally the DNS clients make requests via UDP. But when the DNS server is behind the NAT the UDP requests will not work.

for (int i=0;i < Table.Rows.Count;i++)
{
      Var YourValue = Table.Rows[i]["ColumnName"];
}

If you want to authenticate against a user name and password and without an authorization cookie, the MVC4 Authorize attribute won't work out of the box. However, you can add the following helper method to your controller to accept basic authentication headers. Call it from the beginning of your controller's methods.

void EnsureAuthenticated(string role)
{
    string[] parts = UTF8Encoding.UTF8.GetString(Convert.FromBase64String(Request.Headers.Authorization.Parameter)).Split(':');
    if (parts.Length != 2 || !Membership.ValidateUser(parts[0], parts[1]))
        throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "No account with that username and password"));
    if (role != null && !Roles.IsUserInRole(parts[0], role))
        throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "An administrator account is required"));
}

From the client side, this helper creates a HttpClient with the authentication header in place:

static HttpClient CreateBasicAuthenticationHttpClient(string userName, string password)
{
    var client = new HttpClient();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(UTF8Encoding.UTF8.GetBytes(userName + ':' + password)));
    return client;
}

I know this is very old thread running, but still EF has not fixed this. For people using auto-generated DbContext can use the following code to set the timeout manually.

public partial class SampleContext : DbContext
{
    public SampleContext()
        : base("name=SampleContext")
    {
        this.SetCommandTimeOut(180);
    }

    public void SetCommandTimeOut(int Timeout)
    {
        var objectContext = (this as IObjectContextAdapter).ObjectContext;
        objectContext.CommandTimeout = Timeout;
    }

I also had the same issue while using http://www.mocky.io/ what i did is to add in mock.io response header: Access-Control-Allow-Origin *

To add it there just need to click on advanced options

Once this is done, my application was able to retrieve the data from external domain.

It doesn't "fail"; it just stops reading. It sees a lexical token as a "string".

Use std::getline:

int main()
{
   std::string name, title;

   std::cout << "Enter your name: ";
   std::getline(std::cin, name);

   std::cout << "Enter your favourite movie: ";
   std::getline(std::cin, title);

   std::cout << name << "'s favourite movie is " << title;
}

Note that this is not the same as std::istream::getline, which works with C-style char buffers rather than std::strings.

Update

Your edited question bears little resemblance to the original.

You were trying to getline into an int, not a string or character buffer. The formatting operations of streams only work with operator<< and operator>>. Either use one of them (and tweak accordingly for multi-word input), or use getline and lexically convert to int after-the-fact.

I've tried various methods like LAB color space, HSV comparisons and I've found that luminosity works pretty well for this purpose.

Here is Python version

def lum(c):
    def factor(component):
        component = component / 255;
        if (component <= 0.03928):
            component = component / 12.92;
        else:
            component = math.pow(((component + 0.055) / 1.055), 2.4);

        return component
    components = [factor(ci) for ci in c]

    return (components[0] * 0.2126 + components[1] * 0.7152 + components[2] * 0.0722) + 0.05;

def color_distance(c1, c2):

    l1 = lum(c1)
    l2 = lum(c2)
    higher = max(l1, l2)
    lower = min(l1, l2)

    return (higher - lower) / higher


c1 = ImageColor.getrgb('white')
c2 = ImageColor.getrgb('yellow')
print(color_distance(c1, c2))

Will give you

0.0687619047619048

You can rollback the statements you've executed within a transaction. Instead of commiting the transaction, rollback the transaction.

If you have updated something and want to rollback those updates, and you haven't done this inside a (not-yet-commited) transaction, then I think it's though luck ...

Based on @md-nazrul-islam reply, This is what I did with SCSS:

ul.ui-autocomplete {
    position: absolute;
    top: 100%;
    left: 0;
    z-index: 1000;
    float: left;
    display: none;
    min-width: 160px;
    margin: 0 0 10px 25px;
    list-style: none;
    background-color: #ffffff;
    border: 1px solid #ccc;
    border-color: rgba(0, 0, 0, 0.2);
    //@include border-radius(5px);
    @include box-shadow( rgba(0, 0, 0, 0.1) 0 5px 10px );
    @include background-clip(padding-box);
    *border-right-width: 2px;
    *border-bottom-width: 2px;

    li.ui-menu-item{
        padding:0 .5em;
        line-height:2em;
        font-size:.8em;
        &.ui-state-focus{
            background: #F7F7F7;
        }
    }

}

In the MySQL interactive client you can type:

source yourfile.sql

Alternatively you can pipe the data into mysql from the command line:

mysql < yourfile.sql

If the file doesn't specify a database then you will also need to add that:

mysql db_name < yourfile.sql

See the documentation for more details:

• Executing SQL Statements from a Text File

since you followed the tutorial, I presume you have a screen that says Hello World.

that means you have some code in your layout xml that looks like this

<TextView        
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

you want to display an image, so instead of TextView you want to have ImageView. and instead of a text attribute you want an src attribute, that links to your drawable resource

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/cool_pic"
/>

'C:/PHP/5.2.13/ext\php_mcrypt1.dll'

I'd say there's some typo on your php.ini (the extra 1). Perhaps you're loading a different php.ini from what you expect (see the output of php.ini to make sure).

Other than that make sure that php_mcrypt.dll and PHP:

Were linked to the same VC runtime library (typically msvcrt.dll for VC6 or msvcrt90.dll for VC9) – use e.g. the dependency walker for this Are both debug builds or both release builds Both have ZTS enabled or ZTS disabled For libraries that depend on further libraries (DLLs), make sure they are available (e.g. in the same directory as the extension) PHP should give you meaning errors if any of the first three conditions above is not satisfied, but I wrote those anyway because I'm not sure for PHP 5.2.

> is not in the documentation.

< is for one-way binding.

@ binding is for passing strings. These strings support {{}} expressions for interpolated values.

= binding is for two-way model binding. The model in parent scope is linked to the model in the directive's isolated scope.

& binding is for passing a method into your directive's scope so that it can be called within your directive.

When we are setting scope: true in directive, Angular js will create a new scope for that directive. That means any changes made to the directive scope will not reflect back in parent controller.

Also, the way strings are implemented (different for each platform) and when you start stitching them together. Like using a StringBuilder. It allocats a buffer for you to copy into, once you reach the end, it allocates even more memory for you, in the hopes that if you do a large concatenation performance won't be hindered.

Maybe Jon Skeet can help up out here?

I hate rsync! ;) So why not use find and cp? And with this answer also mkdir to create a non-existent folder structure.

cd /source_folder/ && find . -type d -not -path '*/not-from-here/*' -print -exec mkdir -p '/destination_folder/{}' \;

cd /source_folder/ && find . -type f -not -path '*/not-from-here/*' -print -exec cp -au '{}' '/destination_folder/{}' \;

It looks like cd ìs necessary to concat relative paths with find.

mkdir -p will create all subfolders and will not complain when a folder already exists.

Housten we have the next problem. What happens when someone creates a new folder with a new file in the middle of it? Exactly: it will fail for these new files. (Solution: just run it again! :)) The solution to put everything into one find command seems difficult.

Ctrl+P and Type "ext install cpptools" it will install everything you need to debug c and c++.

Debugging in VS code is very complete, but if you just need to compile and run: https://code.visualstudio.com/docs/languages/cpp

Look in the debugging section and it will explain everything

git diff --shortstat

gives you just the number of lines changed and added. This only works with unstaged changes. To compare against a branch:

git diff --shortstat some-branch

I needed my ASP.NET drop down list to take up all available space, and this is all I put in the CSS and it is working in Firefox and IE11:

width: 100%

I had to add the CSS class into the asp:DropDownList element

I have a Toolbar in my Activity and a Base Activity that overrides all Titles. So I had to use setTitle in onResume() in the Activity like so:

@Override
  protected void onResume() {
    super.onResume();
    toolbar.setTitle(R.string.title);
  }

Some safer alternatives to eval() and sympy.sympify().evalf()^*:

• asteval
• numexpr

^*SymPy sympify is also unsafe according to the following warning from the documentation.

Warning: Note that this function uses eval, and thus shouldn’t be used on unsanitized input.

If you mean the screen where you have that interpreter prompt >>> you can do CTRL+L on Bash shell can help. Windows does not have equivalent. You can do

import os
os.system('cls')  # on windows

or

os.system('clear')  # on linux / os x

The only problem could be if one day

map[key] = value

will transform to -

map[key]++;

and that will cause a KeyNotFoundException.

You can try with this, it worked for me

WebView wb_previewSurvey=new WebView(this); 


       wb_previewSurvey.setWebChromeClient(new WebChromeClient() {
        @Override
        public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
            //Required functionality here
            return super.onJsAlert(view, url, message, result);
        }

    });

If you want a new object with two keys, Object1 and Object2, you can do:

JSONObject Obj1 = (JSONObject) jso1.get("Object1");
JSONObject Obj2 = (JSONObject) jso2.get("Object2");
JSONObject combined = new JSONObject();
combined.put("Object1", Obj1);
combined.put("Object2", Obj2);

If you want to merge them, so e.g. a top level object has 5 keys (Stringkey1, ArrayKey, StringKey2, StringKey3, StringKey4), I think you have to do that manually:

JSONObject merged = new JSONObject(Obj1, JSONObject.getNames(Obj1));
for(String key : JSONObject.getNames(Obj2))
{
  merged.put(key, Obj2.get(key));
}

This would be a lot easier if JSONObject implemented Map, and supported putAll.

import os
os.system('pip install requests')

I tried above for temporary solution instead of changing docker file. Hope these might be useful to some

You can use this:

DateTime.Now.ToString("yyyy-dd-M--HH-mm-ss");

try out this if you want to assign value to object and it is showing this error in angular..

crate object in construtor

this.modelObj = new Model(); //<---------- after declaring object above

SOLUTIONS

1. Sometimes the project is created before installing g++. So install g++ first and then recreate your project. This worked for me.
2. Paste the following line in CMakeCache.txt: CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++

Note the path to g++ depends on OS. I have used my fedora path obtained using which g++

There is also https://github.com/Valloric/YouCompleteMe and it includes things like Jedi and also has fuzzy match. So far I found YCM to be the fastest among what I have tried.

Edit: There also exists some new ones like https://github.com/maralla/completor.vim

This is by far the easiest approach, works on non-blocking elements as well, the only downside is, it's Flexbox, thus, older browsers will not support this.

<div class="sweet-overlay">
    <img class="centered" src="http://jimpunk.com/Loading/loading83.gif" />
</div>

Link to codepen:

http://codepen.io/damianocel/pen/LNOdRp

The important point here is, for vertical centering, we need to define a parent element (container) and the img must have a smaller height than the parent element.

Since it's in bootstrap 3, the site will be using jQuery. So the solution could also be the following, instead of trying to play with complex CSS:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
    <link href="css/bootstrap.min.css" rel="stylesheet" />
    <style>
        .my-footer {
            border-radius : 0px;
            margin : 0px; /* pesky margin below .navbar */
            position : absolute;
            width : 100%;
        }
    </style>
</head>
<body>
    <div class="container-fluid">
        <div class="row">
            <!-- Content of any length -->
            asdfasdfasdfasdfs <br />
            asdfasdfasdfasdfs <br />
            asdfasdfasdfasdfs <br />
        </div>
    </div>

    <div class="navbar navbar-inverse my-footer">
        <div class="container-fluid">
            <div class="row">
                <p class="navbar-text">My footer content goes here...</p>
            </div>
        </div>
    </div>

    <script src="js/jquery-1.11.0.min.js"></script>
    <script src="js/bootstrap.min.js"></script>

    <script type="text/javascript">
        $(document).ready(function () {
            var $docH = $(document).height();
            // The document height will grow as the content on the page grows.
            $('.my-footer').css({
                /*
                The default height of .navbar is 50px with a 1px border,
                change this 52 if you change the height of your footer.
                */
                top: ($docH - 52) + 'px'
            });
        });
    </script>
</body>
</html>

A different take on it, hope it helps.

Kind regards.

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;
/

CREATE TABLE someTable (
    id serial PRIMARY KEY,
    col1 int NOT NULL,
    col2 int NOT NULL,
    UNIQUE (col1, col2)
)

autoincrement is not postgresql. You want a serial.

If col1 and col2 make a unique and can't be null then they make a good primary key:

CREATE TABLE someTable (
    col1 int NOT NULL,
    col2 int NOT NULL,
    PRIMARY KEY (col1, col2)
)

This approach is ok but will not work for when you get params dynamically , sometimes 1, 2, 3 or more, just like a SOLR search query (for example)

Here is a more flexible solution. Crude but can be refined.

public static void main(String[] args) {

    String host = "localhost";
    String port = "9093";

    String param = "/10-2014.01?description=cars&verbose=true&hl=true&hl.simple.pre=<b>&hl.simple.post=</b>";
    String[] wholeString = param.split("\\?");
    String theQueryString = wholeString.length > 1 ? wholeString[1] : "";

    String SolrUrl = "http://" + host + ":" + port + "/mypublish-services/carclassifications/" + "loc";

    GetMethod method = new GetMethod(SolrUrl );

    if (theQueryString.equalsIgnoreCase("")) {
        method.setQueryString(new NameValuePair[]{
        });
    } else {
        String[] paramKeyValuesArray = theQueryString.split("&");
        List<String> list = Arrays.asList(paramKeyValuesArray);
        List<NameValuePair> nvPairList = new ArrayList<NameValuePair>();
        for (String s : list) {
            String[] nvPair = s.split("=");
            String theKey = nvPair[0];
            String theValue = nvPair[1];
            NameValuePair nameValuePair = new NameValuePair(theKey, theValue);
            nvPairList.add(nameValuePair);
        }
        NameValuePair[] nvPairArray = new NameValuePair[nvPairList.size()];
        nvPairList.toArray(nvPairArray);
        method.setQueryString(nvPairArray);       // Encoding is taken care of here by setQueryString

    }
}

I found that these CSS styles force the page to always scroll to top on reload/refresh:

html {
    height: 100%;
    overflow: hidden;
    width: 100%;
}

body {
    height: 100%;
    overflow-x: hidden;
    overflow-y: auto;
    width: 100%;
}

So I have ElementTree 1.2.6 on my box now, and ran the following code against the XML chunk you posted:

import elementtree.ElementTree as ET

tree = ET.parse("test.xml")
doc = tree.getroot()
thingy = doc.find('timeSeries')

print thingy.attrib

and got the following back:

{'name': 'NWIS Time Series Instantaneous Values'}

It appears to have found the timeSeries element without needing to use numerical indices.

What would be useful now is knowing what you mean when you say "it doesn't work." Since it works for me given the same input, it is unlikely that ElementTree is broken in some obvious way. Update your question with any error messages, backtraces, or anything you can provide to help us help you.

Try this in your code:

import Foo from './Foo';
import Bar from './Bar';

// without default
export {
  Foo,
  Bar,
}

Btw, you can also do it this way:

// bundle.js
export { default as Foo } from './Foo'
export { default as Bar } from './Bar'
export { default } from './Baz'

// and import somewhere..
import Baz, { Foo, Bar } from './bundle'

Using export

export const MyFunction = () => {}
export const MyFunction2 = () => {}

const Var = 1;
const Var2 = 2;

export {
   Var,
   Var2,
}


// Then import it this way
import {
  MyFunction,
  MyFunction2,
  Var,
  Var2,
} from './foo-bar-baz';

The difference with export default is that you can export something, and apply the name where you import it:

// export default
export default class UserClass {
  constructor() {}
};

// import it
import User from './user'

You can't alter the existing columns for identity.

You have 2 options,

Create a new table with identity & drop the existing table

Create a new column with identity & drop the existing column

Approach 1. (New table) Here you can retain the existing data values on the newly created identity column.

CREATE TABLE dbo.Tmp_Names
    (
      Id int NOT NULL
             IDENTITY(1, 1),
      Name varchar(50) NULL
    )
ON  [PRIMARY]
go

SET IDENTITY_INSERT dbo.Tmp_Names ON
go

IF EXISTS ( SELECT  *
            FROM    dbo.Names ) 
    INSERT  INTO dbo.Tmp_Names ( Id, Name )
            SELECT  Id,
                    Name
            FROM    dbo.Names TABLOCKX
go

SET IDENTITY_INSERT dbo.Tmp_Names OFF
go

DROP TABLE dbo.Names
go

Exec sp_rename 'Tmp_Names', 'Names'

Approach 2 (New column) You can’t retain the existing data values on the newly created identity column, The identity column will hold the sequence of number.

Alter Table Names
Add Id_new Int Identity(1, 1)
Go

Alter Table Names Drop Column ID
Go

Exec sp_rename 'Names.Id_new', 'ID', 'Column'

See the following Microsoft SQL Server Forum post for more details:

http://social.msdn.microsoft.com/forums/en-US/transactsql/thread/04d69ee6-d4f5-4f8f-a115-d89f7bcbc032

Maybe this way:

const m = new Map([["a", 1], ["b", 2], ["c", 3]]);
m.map((k, v) => [k, v * 2]); // Map { 'a' => 2, 'b' => 4, 'c' => 6 }

You would only need to monkey patch Map before:

Map.prototype.map = function(func){
    return new Map(Array.from(this, ([k, v]) => func(k, v)));
}

We could have wrote a simpler form of this patch:

Map.prototype.map = function(func){
    return new Map(Array.from(this, func));
}

But we would have forced us to then write m.map(([k, v]) => [k, v * 2]); which seems a bit more painful and ugly to me.

Mapping values only

We could also map values only, but I wouldn't advice going for that solution as it is too specific. Nevertheless it can be done and we would have the following API:

const m = new Map([["a", 1], ["b", 2], ["c", 3]]);
m.map(v => v * 2); // Map { 'a' => 2, 'b' => 4, 'c' => 6 }

Just like before patching this way:

Map.prototype.map = function(func){
    return new Map(Array.from(this, ([k, v]) => [k, func(v)]));
}

Maybe you can have both, naming the second mapValues to make it clear that you are not actually mapping the object as it would probably be expected.

I came up with an ultra-simple solution:

import datetime

def calcEpochSec(dt):
    epochZero = datetime.datetime(1970,1,1,tzinfo = dt.tzinfo)
    return (dt - epochZero).total_seconds()

It works with both timezone-aware and timezone-naive datetime values. And no additional libraries or database workarounds are required.

Swift 3.0 in Xcode 8

Swift 3.0 has replaced many "stringly-typed" APIs with struct "wrapper types", as is the case with NotificationCenter. Notifications are now identified by a struct Notfication.Name rather than by String. See the Migrating to Swift 3 guide.

Previous usage:

// Define identifier
let notificationIdentifier: String = "NotificationIdentifier"

// Register to receive notification
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification(_:)), name: notificationIdentifier, object: nil)

// Post a notification
NSNotificationCenter.defaultCenter().postNotificationName(notificationIdentifier, object: nil)

New Swift 3.0 usage:

// Define identifier
let notificationName = Notification.Name("NotificationIdentifier")

// Register to receive notification
NotificationCenter.default.addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification), name: notificationName, object: nil)

// Post notification
NotificationCenter.default.post(name: notificationName, object: nil)

All of the system notification types are now defined as static constants on Notification.Name; i.e. .UIDeviceBatteryLevelDidChange, .UIApplicationDidFinishLaunching, .UITextFieldTextDidChange, etc.

You can extend Notification.Name with your own custom notifications in order to stay consistent with the system notifications:

// Definition:
extension Notification.Name {
    static let yourCustomNotificationName = Notification.Name("yourCustomNotificationName")
}

// Usage:
NotificationCenter.default.post(name: .yourCustomNotificationName, object: nil)

Just use the array of options, to see, which option is currently selected.

$options = array( 'one', 'two', 'three' );

$output = '';
for( $i=0; $i<count($options); $i++ ) {
  $output .= '<option ' 
             . ( $_GET['sel'] == $options[$i] ? 'selected="selected"' : '' ) . '>' 
             . $options[$i] 
             . '</option>';
}

_{Sidenote: I would define a value to be some kind of id for each element, else you may run into problems, when two options have the same string representation.}

I was trying to use aws-vault which uses pass and gnugp2 (gpg2). I'm on Ubuntu 20.04 running in WSL2.

I tried all the solutions above, and eventually, I had to do one more thing -

$ rm ~/.gnupg/S.*                    # remove cache
$ gpg-connect-agent reloadagent /bye # restart gpg agent
$ export GPG_TTY=$(tty)              # prompt for password
# ^ This last line should be added to your ~/.bashrc file

The source of this solution is from some blog-post in Japanese, luckily there's Google Translate :)

npm outdated will identify packages that should be updated, and npm update <package name> can be used to update each package. But prior to [email protected], npm update <package name> will not update the versions in your package.json which is an issue.

The best workflow is to:

1. Identify out of date packages
2. Update the versions in your package.json
3. Run npm update to install the latest versions of each package

Check out npm-check-updates to help with this workflow.

• Install npm-check-updates
• Run npm-check-updates to list what packages are out of date (basically the same thing as running npm outdated)
• Run npm-check-updates -u to update all the versions in your package.json (this is the magic sauce)
• Run npm update as usual to install the new versions of your packages based on the updated package.json

You can actualy fake the transparency of option DOMElements with the following CSS:

CSS

option { 
    /* Whatever color  you want */
    background-color: #82caff;
}

See Demo

The option tag does not support rgba colors yet.

Can't you surround it with an a tag?

  <a href="#"><div id="buttonOne">
        <div id="linkedinB">
            <img src="img/linkedinB.png" width="40" height="40">
        </div>
  </div></a>

Here's the documentation:

https://dev.mysql.com/doc/connector-j/en/connector-j-reference-configuration-properties.html

A basic connection string looks like:

jdbc:mysql://localhost:3306/dbname

The class.forName string is "com.mysql.jdbc.Driver", which you can find (edit: now on the same page).

You do cls.isFilled = True. That overwrites the method called isFilled and replaces it with the value True. That method is now gone and you can't call it anymore. So when you try to call it again you get an error, since it's not there anymore.

The solution is use a different name for the variable than you do for the method.

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

In Linux it's more likely that extensions to existing editors will be more mature than entirely new ones. Thus, the two stalwarts (vi and emacs) are likely to have packages available.

EDIT: Indeed, here's the vi one:

http://vim-latex.sourceforge.net/

... and here's the emacs one:

http://www.gnu.org/software/auctex/

I have to say, I'm a vi man, but the emacs package looks rather spiffy: it includes the ability to embed preview images of formulas in your emacs buffer.

Ok. I found a solution.

You can also use eval:

FOO=bar eval 'somecommand someargs | somecommand2'

Since this answer with eval doesn't seem to please everyone, let me clarify something: when used as written, with the single quotes, it is perfectly safe. It is good as it will not launch an external process (like the accepted answer) nor will it execute the commands in an extra subshell (like the other answer).

As we get a few regular views, it's probably good to give an alternative to eval that will please everyone, and has all the benefits (and perhaps even more!) of this quick eval “trick”. Just use a function! Define a function with all your commands:

mypipe() {
    somecommand someargs | somecommand2
}

and execute it with your environment variables like this:

FOO=bar mypipe

The shell command is collapsed into a single line, as in ls --color /home

Combining R.. and PickBoy answers for brevity

In the year 2019, Microsoft offers the following solution for Windows 10. This solution works for SHA256 checksum.

https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/get-filehash?view=powershell-6

Press the Windows key. Type PowerShell. Select Windows Powershell. Press Enter key. Paste the command

Get-FileHash C:\Users\Donald\Downloads\File-to-be-checked-by-sha256.exe | Format-List

Replace File-to-be-checked-by-sha256.exe by the name of your file to be checked.

Replace the path to your path where the file is. Press Enter key. Powershell shows then the following

Algorithm : SHA256 Hash : 123456789ABCDEFGH1234567890... Path : C:\Users\Donald\Downloads\File-to-be-checked-by-sha256.exe

You can actually modify your user settings and edit each colour individually by adding the following to the user settings.

1. Open user settings (ctrl + ,)
2. Search for workbench and select Edit in settings.json under Color Customizations

"workbench.colorCustomizations" : {
    "terminal.foreground" : "#00FD61",
    "terminal.background" : "#383737"
}

For more on what colors you can edit you can find out here.

There are no PowerShell-native commands for Base64 conversion - yet (as of PowerShell [Core] 7.1), but adding dedicated cmdlets has been suggested.
For now, direct use of .NET is needed.

Important:

• Base64 encoding is an encoding of binary data using bytes whose values are constrained to a well-defined 64-character subrange of the ASCII character set representing printable characters, devised at a time when sending arbitrary bytes was problematic, especially with the high bit set (byte values > 0x7f).

• Therefore, you must always specify explicitly what character encoding the Base64 bytes do / should represent.

Ergo:

• on converting TO Base64, you must first obtain a byte representation of the string you're trying to encode using the character encoding the consumer of the Base64 string expects.

• on converting FROM Base64, you must interpret the resultant array of bytes as a string using the same encoding that was used to create the Base64 representation.

Examples:

Note:

• The following examples convert to and from UTF-8 encoded strings:

• To convert to and from UTF-16LE ("Unicode") instead, substitute [Text.Encoding]::Unicode for [Text.Encoding]::UTF8

Convert TO Base64:

PS> [Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes('Motörhead'))
TW90w7ZyaGVhZA==

Convert FROM Base64:

PS> [Text.Encoding]::Utf8.GetString([Convert]::FromBase64String('TW90w7ZyaGVhZA=='))
Motörhead

Another method that people should consider using is Shared Workers. I know it's a cutting edge concept, but you can create a relay on a Shared Worker that is MUCH faster than localstorage, and doesn't require a relationship between the parent/child window, as long as you're on the same origin.

See my answer here for some discussion I made about this.

If you are using the ‘static’ keyword without the ‘final’ keyword, this should be a signal to carefully consider your design. Even the presence of a ‘final’ is not a free pass, since a mutable static final object can be just as dangerous.

I would estimate somewhere around 85% of the time I see a ‘static’ without a ‘final’, it is WRONG. Often, I will find strange workarounds to mask or hide these problems.

Please don’t create static mutables. Especially Collections. In general, Collections should be initialized when their containing object is initialized and should be designed so that they are reset or forgotten about when their containing object is forgotten.

Using statics can create very subtle bugs which will cause sustaining engineers days of pain. I know, because I’ve both created and hunted these bugs.

If you would like more details, please read on…

Why Not Use Statics?

There are many issues with statics, including writing and executing tests, as well as subtle bugs that are not immediately obvious.

Code that relies on static objects can’t be easily unit tested, and statics can’t be easily mocked (usually).

If you use statics, it is not possible to swap the implementation of the class out in order to test higher level components. For example, imagine a static CustomerDAO that returns Customer objects it loads from the database. Now I have a class CustomerFilter, that needs to access some Customer objects. If CustomerDAO is static, I can’t write a test for CustomerFilter without first initializing my database and populating useful information.

And database population and initialization takes a long time. And in my experience, your DB initialization framework will change over time, meaning data will morph, and tests may break. IE, imagine Customer 1 used to be a VIP, but the DB initialization framework changed, and now Customer 1 is no longer VIP, but your test was hard-coded to load Customer 1…

A better approach is to instantiate a CustomerDAO, and pass it into the CustomerFilter when it is constructed. (An even better approach would be to use Spring or another Inversion of Control framework.

Once you do this, you can quickly mock or stub out an alternate DAO in your CustomerFilterTest, allowing you to have more control over the test,

Without the static DAO, the test will be faster (no db initialization) and more reliable (because it won’t fail when the db initialization code changes). For example, in this case ensuring Customer 1 is and always will be a VIP, as far as the test is concerned.

Executing Tests

Statics cause a real problem when running suites of unit tests together (for example, with your Continuous Integration server). Imagine a static map of network Socket objects that remains open from one test to another. The first test might open a Socket on port 8080, but you forgot to clear out the Map when the test gets torn down. Now when a second test launches, it is likely to crash when it tries to create a new Socket for port 8080, since the port is still occupied. Imagine also that Socket references in your static Collection are not removed, and (with the exception of WeakHashMap) are never eligible to be garbage collected, causing a memory leak.

This is an over-generalized example, but in large systems, this problem happens ALL THE TIME. People don’t think of unit tests starting and stopping their software repeatedly in the same JVM, but it is a good test of your software design, and if you have aspirations towards high availability, it is something you need to be aware of.

These problems often arise with framework objects, for example, your DB access, caching, messaging, and logging layers. If you are using Java EE or some best of breed frameworks, they probably manage a lot of this for you, but if like me you are dealing with a legacy system, you might have a lot of custom frameworks to access these layers.

If the system configuration that applies to these framework components changes between unit tests, and the unit test framework doesn’t tear down and rebuild the components, these changes can’t take effect, and when a test relies on those changes, they will fail.

Even non-framework components are subject to this problem. Imagine a static map called OpenOrders. You write one test that creates a few open orders, and checks to make sure they are all in the right state, then the test ends. Another developer writes a second test which puts the orders it needs into the OpenOrders map, then asserts the number of orders is accurate. Run individually, these tests would both pass, but when run together in a suite, they will fail.

Worse, failure might be based on the order in which the tests were run.

In this case, by avoiding statics, you avoid the risk of persisting data across test instances, ensuring better test reliability.

Subtle Bugs

If you work in high availability environment, or anywhere that threads might be started and stopped, the same concern mentioned above with unit test suites can apply when your code is running on production as well.

When dealing with threads, rather than using a static object to store data, it is better to use an object initialized during the thread’s startup phase. This way, each time the thread is started, a new instance of the object (with a potentially new configuration) is created, and you avoid data from one instance of the thread bleeding through to the next instance.

When a thread dies, a static object doesn’t get reset or garbage collected. Imagine you have a thread called “EmailCustomers”, and when it starts it populates a static String collection with a list of email addresses, then begins emailing each of the addresses. Lets say the thread is interrupted or canceled somehow, so your high availability framework restarts the thread. Then when the thread starts up, it reloads the list of customers. But because the collection is static, it might retain the list of email addresses from the previous collection. Now some customers might get duplicate emails.

An Aside: Static Final

The use of “static final” is effectively the Java equivalent of a C #define, although there are technical implementation differences. A C/C++ #define is swapped out of the code by the pre-processor, before compilation. A Java “static final” will end up memory resident on the stack. In that way, it is more similar to a “static const” variable in C++ than it is to a #define.

Summary

I hope this helps explain a few basic reasons why statics are problematic up. If you are using a modern Java framework like Java EE or Spring, etc, you may not encounter many of these situations, but if you are working with a large body of legacy code, they can become much more frequent.

I assume that you want to read input from the console. If so, use Read-Host.

You can use .change()

$('input[name=myInput]').change(function() { ... });

However, this event will only fire when the selector has lost focus, so you will need to click somewhere else to have this work.

If that's not quite right for you, you could use some of the other jQuery events like keyup, keydown or keypress - depending on the exact effect you want.

You just put them in __init__.py.

So with test/classes.py being:

class A(object): pass
class B(object): pass

... and test/__init__.py being:

from classes import *

class Helper(object): pass

You can import test and have access to A, B and Helper

>>> import test
>>> test.A
<class 'test.classes.A'>
>>> test.B
<class 'test.classes.B'>
>>> test.Helper
<class 'test.Helper'>

It isn't a tag…

But if you have it, you risk having white space after it.

If you then use it as an include at the top of a document, you could end up inserting white space (i.e. content) before you attempt to send HTTP headers … which isn't allowed.

Here is an example using a generator's send() method:

def restartable(seq):
    while True:
        for item in seq:
            restart = yield item
            if restart:
                break
        else:
            raise StopIteration

Example Usage:

x = [1, 2, 3, 4, 5]
total = 0
r = restartable(x)
for item in r:
    if item == 5 and total < 100:
        total += r.send(True) 
    else:
        total += item

If you're wanting this as a script, the following Bash script should do what you want (plus tell you when the file already exists):

#!/bin/bash
if [ -e $1 ]; then
  echo "File $1 already exists!"
else
  echo >> $1
fi

If you don't want the "already exists" message, you can use:

#!/bin/bash
if [ ! -e $1 ]; then
  echo >> $1
fi

Edit about using:

Save whichever version with a name you like, let's say "create_file" (quotes mine, you don't want them in the file name). Then, to make the file executatble, at a command prompt do:

chmod u+x create_file

Put the file in a directory in your path, then use it with:

create_file NAME_OF_NEW_FILE

The $1 is a special shell variable which takes the first argument on the command line after the program name; i.e. $1 will pick up NAME_OF_NEW_FILE in the above usage example.

You can simply use:

$('#select_id').val('fg')

1. insert into mytable(id, myblob) values (1,EMPTY_BLOB);
2. SELECT * FROM mytable mt where mt.id=1 for update
3. Click on the Lock icon to unlock for editing
4. Click on the ... next to the BLOB to edit
5. Select the appropriate tab and click open on the top left.
6. Click OK and commit the changes.

"Plain Old C# Object"

Just a normal class, no attributes describing infrastructure concerns or other responsibilities that your domain objects shouldn't have.

EDIT - as other answers have stated, it is technically "Plain Old CLR Object" but I, like David Arno comments, prefer "Plain Old Class Object" to avoid ties to specific languages or technologies.

TO CLARIFY: In other words, they don’t derive from some special base class, nor do they return any special types for their properties.

See below for an example of each.

Example of a POCO:

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

    public int Age { get; set; }
}

Example of something that isn’t a POCO:

public class PersonComponent : System.ComponentModel.Component
{
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
    public string Name { get; set; }

    public int Age { get; set; }
}

The example above both inherits from a special class to give it additional behavior as well as uses a custom attribute to change behavior… the same properties exist on both classes, but one is not just a plain old object anymore.

Just a helpful hint, there is a company called Yodlee.com who provides this data. They do charge for the API. Companies like Mint.com use this API to gather bank and financial account data.

Also, checkout https://plaid.com/, they are a similar company Yodlee.com and provide both authentication API for several banks and REST-based transaction fetching endpoints.
