You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace); CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession); CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);
See a better answer below: https://stackoverflow.com/a/10054088/308315
Old answer:
First, in your AppDelegate .h file:
#import <AVFoundation/AVFoundation.h>
@interface AppDelegate : NSObject <UIApplicationDelegate> {
AVCaptureSession *torchSession;
}
@property (nonatomic, retain) AVCaptureSession * torchSession;
@end
Then in your AppDelegate .m file:
@implementation AppDelegate
@synthesize torchSession;
- (void)dealloc {
[torchSession release];
[super dealloc];
}
- (id) init {
if ((self = [super init])) {
// initialize flashlight
// test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {
AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
if ([device hasTorch] && [device hasFlash]){
if (device.torchMode == AVCaptureTorchModeOff) {
NSLog(@"Setting up flashlight for later use...");
AVCaptureDeviceInput *flashInput = [AVCaptureDeviceInput deviceInputWithDevice:device error: nil];
AVCaptureVideoDataOutput *output = [[AVCaptureVideoDataOutput alloc] init];
AVCaptureSession *session = [[AVCaptureSession alloc] init];
[session beginConfiguration];
[device lockForConfiguration:nil];
[session addInput:flashInput];
[session addOutput:output];
[device unlockForConfiguration];
[output release];
[session commitConfiguration];
[session startRunning];
[self setTorchSession:session];
[session release];
}
}
}
}
return self;
}
Then anytime you want to turn it on, just do something like this:
// test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {
AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
[device lockForConfiguration:nil];
[device setTorchMode:AVCaptureTorchModeOn];
[device setFlashMode:AVCaptureFlashModeOn];
[device unlockForConfiguration];
}
And similar for turning it off:
// test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {
AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
[device lockForConfiguration:nil];
[device setTorchMode:AVCaptureTorchModeOff];
[device setFlashMode:AVCaptureFlashModeOff];
[device unlockForConfiguration];
}
Not really to answer OP's question (it's resolved anyway), but to help people who may stumble into the similar issue.
Here is what we had:

Maybe someone will find this solution useful:
void print_binary(int number, int num_digits) {
int digit;
for(digit = num_digits - 1; digit >= 0; digit--) {
printf("%c", number & (1 << digit) ? '1' : '0');
}
}
All answers here are still using the FormData API. It is like a "multipart/form-data"
upload without a form. You can also upload the file directly as content inside the body of the POST
request using xmlHttpRequest
like this:
var xmlHttpRequest = new XMLHttpRequest();
var file = ...file handle...
var fileName = ...file name...
var target = ...target...
var mimeType = ...mime type...
xmlHttpRequest.open('POST', target, true);
xmlHttpRequest.setRequestHeader('Content-Type', mimeType);
xmlHttpRequest.setRequestHeader('Content-Disposition', 'attachment; filename="' + fileName + '"');
xmlHttpRequest.send(file);
Content-Type
and Content-Disposition
headers are used for explaining what we are sending (mime-type and file name).
I posted similar answer also here.
In Python-style regex, \d
matches any individual digit. If you're seeing something that doesn't seem to do that, please provide the full regex you're using, as opposed to just describing that one particular symbol.
>>> import re
>>> re.match(r'\d', '3')
<_sre.SRE_Match object at 0x02155B80>
>>> re.match(r'\d', '2')
<_sre.SRE_Match object at 0x02155BB8>
>>> re.match(r'\d', '1')
<_sre.SRE_Match object at 0x02155B80>
In JavaScript this:
var something = 12;
function nicelyCraftedFunction()
{
something = 13;
// ... some other code
// ... and in Galaxy far, far away this:
if( false ) // so the block never executes:
{
var something;
}
}
nicelyCraftedFunction(); // call of the function
Normally you would expect that something
variable will get value of 13.
But not in JavaScript - variables there have function scope so later declaration affects everything up-stream.
In languages that use C/C++/Java notation (like JS) you would expect variables having block scope, not like this ...
So dead block of code that compiler can even remove from final generated bytecode still have side effects in the rest of code that executes normally.
Therefore something
will be still 12
- not change after invocation of the function.
One can also bind a function with ng-change
event listener, if they need to run a bit more complex logic.
<div ng-app="myApp" ng-controller="myCtrl">
<input type='text' ng-model='name' ng-change='change()'>
<br/> <span>changed {{counter}} times </span>
</div>
...
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.name = 'Australia';
$scope.counter = 0;
$scope.change = function() {
$scope.counter++;
};
});

As dudewat said external linkage means the symbol (function or global variable) is accessible throughout your program and internal linkage means that it is only accessible in one translation unit.
You can explicitly control the linkage of a symbol by using the extern
and static
keywords. If the linkage is not specified then the default linkage is extern
(external linkage) for non-const
symbols and static
(internal linkage) for const
symbols.
// In namespace scope or global scope.
int i; // extern by default
const int ci; // static by default
extern const int eci; // explicitly extern
static int si; // explicitly static
// The same goes for functions (but there are no const functions).
int f(); // extern by default
static int sf(); // explicitly static
Note that instead of using static
(internal linkage), it is better to use anonymous namespaces into which you can also put class
es. Though they allow extern
linkage, anonymous namespaces are unreachable from other translation units, making linkage effectively static
.
namespace {
int i; // extern by default but unreachable from other translation units
class C; // extern by default but unreachable from other translation units
}
You may also want to use Rake::FileList
(provided you have rake
dependency):
FileList.new('lib/*') do |file|
p file
end
According to the API:
FileLists are lazy. When given a list of glob patterns for possible files to be included in the file list, instead of searching the file structures to find the files, a FileList holds the pattern for latter use.
You should use Adaptive hashing like http://en.wikipedia.org/wiki/Bcrypt for securing passwords
SQL Server allows the following (be careful to use single quotes instead of double)
UPDATE User
SET UserId = 12345
, Name = 'J Doe'
, Location = 'USA'
, Bio='my bio
spans
multiple
lines!'
WHERE UserId = 12345
Have you tried escaping the dot? like this:
String[] words = line.split("\\.");
In htop
, you can simply search with
/process-name
close():- Suppose you have opened multiple browser windows with same driver instance, now calling close() on the driver instance will close the current window the driver instance is pointed to. But the driver instance still remain in memory and can be used to handle other open browser windows.
quit():- If you call quit() on the driver instance and there are one or more browser windows open, it will close all the open browser windows and the driver instance is garbage collected i.e. removed from the memory. So now you cannot use this driver instance to do other operation after calling quit() on it. If you do it will throw an Exception.
dispose():- I don't think there is a dispose method for a WebDriver instance.

Consider the below figure and program to understand this concept better.
As per the figure, ptr1 is a single pointer which is having address of variable num.
ptr1 = #
Similarly ptr2 is a pointer to pointer(double pointer) which is having the address of pointer ptr1.
ptr2 = &ptr1;
A pointer which points to another pointer is known as double pointer. In this example ptr2 is a double pointer.
Values from above diagram :
Address of variable num has : 1000
Address of Pointer ptr1 is: 2000
Address of Pointer ptr2 is: 3000
Example:
#include <stdio.h>
int main ()
{
int num = 10;
int *ptr1;
int **ptr2;
// Take the address of var
ptr1 = #
// Take the address of ptr1 using address of operator &
ptr2 = &ptr1;
// Print the value
printf("Value of num = %d\n", num );
printf("Value available at *ptr1 = %d\n", *ptr1 );
printf("Value available at **ptr2 = %d\n", **ptr2);
}
Output:
Value of num = 10
Value available at *ptr1 = 10
Value available at **ptr2 = 10
The default limit for the length of the request line is 8190 bytes (see LimitRequestLine
directive). And if we subtract three bytes for the request method (i.e. GET
), eight bytes for the version information (i.e. HTTP/1.0
/HTTP/1.1
) and two bytes for the separating space, we end up with 8177 bytes for the URI path plus query.
Also, if you had multiple event handlers attached to the same selector executing the same function, you could use
$('table.planning_grid').on('mouseenter mouseleave', function() {
//JS Code
});
I am combining the solutions from answers of @FredFoo and @Renaud. My solution is able to apply @Renaud's preprocessing on the text corpus of @FredFoo and then display pairwise similarities where the similarity is greater than 0. I ran this code on Windows by installing python and pip first. pip is installed as part of python but you may have to explicitly do it by re-running the installation package, choosing modify and then choosing pip. I use the command line to execute my python code saved in a file "similarity.py". I had to execute the following commands:
>set PYTHONPATH=%PYTHONPATH%;C:\_location_of_python_lib_
>python -m pip install sklearn
>python -m pip install nltk
>py similarity.py
The code for similarity.py is as follows:
from sklearn.feature_extraction.text import TfidfVectorizer
import nltk, string
import numpy as np
nltk.download('punkt') # if necessary...
stemmer = nltk.stem.porter.PorterStemmer()
remove_punctuation_map = dict((ord(char), None) for char in string.punctuation)
def stem_tokens(tokens):
return [stemmer.stem(item) for item in tokens]
def normalize(text):
return stem_tokens(nltk.word_tokenize(text.lower().translate(remove_punctuation_map)))
corpus = ["I'd like an apple",
"An apple a day keeps the doctor away",
"Never compare an apple to an orange",
"I prefer scikit-learn to Orange",
"The scikit-learn docs are Orange and Blue"]
vect = TfidfVectorizer(tokenizer=normalize, stop_words='english')
tfidf = vect.fit_transform(corpus)
pairwise_similarity = tfidf * tfidf.T
#view the pairwise similarities
print(pairwise_similarity)
#check how a string is normalized
print(normalize("The scikit-learn docs are Orange and Blue"))
If you used
brew install python
before 'unlink' you got
brew info python
/usr/local/Cellar/python/2.7.11
python -V
Python 2.7.10
so do
brew unlink python && brew link python
and open a new terminal shell
python -V
Python 2.7.11
For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
While this will not (note the leading space before the opening <?
tag)
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
Also, this will not work either (the echo
will break it):
<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.
add ob_start ();
at the top and at the end add ob_end_flush();
<?php
ob_start();
require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
ob_end_flush();
?>
give me an error as below:
FPDF error: Some data has already been output, can't send PDF
to over come this error:
go to fpdf.php
in that,goto line number 996
function Output($name='', $dest='')
after that make changes like this:
function Output($name='', $dest='') {
ob_clean(); //Output PDF to so
Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.
<?

?>
cheers :-)
In my case i had set:
ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);
When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off
the display_errors
option, the report was generated successfully.
This one worked for me:

You can appendChild
to document.body
but not if the document hasn't been loaded. So you should
put everything in:
window.onload=function(){
//your code
}
This works or you can make appendChild
to be dependent on something else like another event for eg.
https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_doc_body_append
As a matter of fact you can try changing the innerHTML
of the document.body
it works...!
One correct answer is:
/a/b/*[self::c or self::d or self::e]
Do note that this
a/b/*[local-name()='c' or local-name()='d' or local-name()='e']
is both too-long and incorrect. This XPath expression will select nodes like:
OhMy:c
NotWanted:d
QuiteDifferent:e
This is happen due to the id(auto increment filed missing). If you edit it in a text editor by adding a comma for the ID field this will be solved.
It'd be easier to do your UPDATE first and then run 'SELECT ID FROM INSERTED'.
Take a look at SQL Tips for more info and examples.
To have a more in-depth knowledge of what's happening, I created the following example. Have a look at the activity_main.xml and content_profile.xml files.
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="@layout/content_profile" />
</LinearLayout>
content_profile.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Howdy" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hi there" />
</LinearLayout>
In here, the entire layout file when inflated looks like this.
<LinearLayout>
<LinearLayout>
<TextView />
<TextView />
</LinearLayout>
</LinearLayout>
See that there is a LinearLayout inside the parent LinearLayout which doesn't serve any purpose and is redundant. A look at the layout through Layout Inspector tool clearly explains this.
content_profile.xml after updating the code to use merge instead of a ViewGroup like LinearLayout.
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Howdy" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hi there" />
</merge>
Now our layout looks like this
<LinearLayout>
<TextView />
<TextView />
</LinearLayout>
Here we see that the redundant LinearLayout ViewGroup is removed. Now Layout Inspector tool gives the following layout hierarchy.
So always try to use merge when your parent layout can position your child layouts, or more precisely use merge when you understand that there is going to be a redundant view group in the hierarchy.
Here is an even simplier way, by writing directly to php error output

To set automatic dimension for row height & estimated row height, ensure following steps to make, auto dimension effective for cell/row height layout.
UITableViewAutomaticDimension
to rowHeight & estimatedRowHeightheightForRowAt
and return a value UITableViewAutomaticDimension
to it)-
Objective C:
// in ViewController.h
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
@property IBOutlet UITableView * table;
@end
// in ViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
self.table.dataSource = self;
self.table.delegate = self;
self.table.rowHeight = UITableViewAutomaticDimension;
self.table.estimatedRowHeight = UITableViewAutomaticDimension;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return UITableViewAutomaticDimension;
}
Swift:
@IBOutlet weak var table: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Don't forget to set dataSource and delegate for table
table.dataSource = self
table.delegate = self
// Set automatic dimensions for row height
// Swift 4.2 onwards
table.rowHeight = UITableView.automaticDimension
table.estimatedRowHeight = UITableView.automaticDimension
// Swift 4.1 and below
table.rowHeight = UITableViewAutomaticDimension
table.estimatedRowHeight = UITableViewAutomaticDimension
}
// UITableViewAutomaticDimension calculates height of label contents/text
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
// Swift 4.2 onwards
return UITableView.automaticDimension
// Swift 4.1 and below
return UITableViewAutomaticDimension
}
For label instance in UITableviewCell
Note: If you've more than one labels (UIElements) with dynamic length, which should be adjusted according to its content size: Adjust 'Content Hugging and Compression Resistance Priority` for labels which you want to expand/compress with higher priority.
I find myself using the following often to get a limited number of revisions out of our huge subversion tree (we're soon reaching svn revision 35000).
# checkout a specific revision
git svn clone -r N svn://some/repo/branch/some-branch
# enter it and get all commits since revision 'N'
cd some-branch
git svn rebase
And a good way to find out where a branch started is to do a svn log
it and find the first one on the branch (the last one listed when doing):
svn log --stop-on-copy svn://some/repo/branch/some-branch
So far I have not really found the hassle worth it in tracking all branches. It takes too much time to clone and svn and git don't work together as good as I would like. I tend to create patch files and apply them on the git clone of another svn branch.
I solved this by adding email accounts in Cpanel and also adding that same email to the header from field like this
$header = 'From: XXXXXXXX <[email protected]>' . "\r\n";
It's also useful for splitting ranges; range(a,b)
can be split into range(a, x)
and range(x, b)
, whereas with inclusive range you would write either x-1
or x+1
. While you rarely need to split ranges, you do tend to split lists quite often, which is one of the reasons slicing a list l[a:b]
includes the a-th element but not the b-th. Then range
having the same property makes it nicely consistent.
Actually this is not a duplicate question. And this how i solve my problem after several times :
int offset = DateTimeZone.forID("anytimezone").getOffset(new DateTime());
This is the way to get offset from desired timezone.
Let's return to our code, we were getting timestamp from a result set of query, and using it with timezone to create our datetime.
DateTime dt = new DateTime(rs.getTimestamp("anytimestampcolumn"),
DateTimeZone.forID("anytimezone"));
Now we will add our offset to the datetime, and get the timestamp from it.
dt = dt.plusMillis(offset);
Timestamp ts = new Timestamp(dt.getMillis());
May be this is not the actual way to get it, but it solves my case. I hope it helps anyone who is stuck here.
You can use bit.ly api to create facebook short urls find the documentation here http://api.bitly.com
Disadvantage of second approach is big repository with created loggers. This loggers do the same if root is defined and class loggers are not defined. Standard scenario on production system is using few loggers dedicated to group of class. Sorry for my English.
Use JSON classes for parsing e.g
JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");
JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
....
If you are able to use ES6 you can use:
function sortArgs(...args) {_x000D_
return args.sort(function (a, b) { return a - b; });_x000D_
}_x000D_
_x000D_
document.body.innerHTML = sortArgs(12, 4, 6, 8).toString();
_x000D_
As you can read in the link
The rest parameter syntax allows us to represent an indefinite number of arguments as an array.
If you are curious about the ...
syntax, it is called Spread Operator and you can read more here.
Using Array.from:
function sortArgs() {_x000D_
return Array.from(arguments).sort(function (a, b) { return a - b; });_x000D_
}_x000D_
_x000D_
document.body.innerHTML = sortArgs(12, 4, 6, 8).toString();
_x000D_
Array.from
simply convert Array-like or Iterable objects into Array instances.
You can actually just use Array
's slice
function on an arguments object, and it will convert it into a standard JavaScript array. You'll just have to reference it manually through Array's prototype:
function sortArgs() {
var args = Array.prototype.slice.call(arguments);
return args.sort();
}
Why does this work? Well, here's an excerpt from the ECMAScript 5 documentation itself:
NOTE: The
slice
function is intentionally generic; it does not require that its this value be an Array object. Therefore it can be transferred to other kinds of objects for use as a method. Whether theslice
function can be applied successfully to a host object is implementation-dependent.
Therefore, slice
works on anything that has a length
property, which arguments
conveniently does.
If Array.prototype.slice
is too much of a mouthful for you, you can abbreviate it slightly by using array literals:
var args = [].slice.call(arguments);
However, I tend to feel that the former version is more explicit, so I'd prefer it instead. Abusing the array literal notation feels hacky and looks strange.
I suppose that
std::to_string(i)
could do the job, it's an overloaded function, it could be any numeric type such as int, double or float
Try clean building your solution. Worked for me.
There's a caveat with the general 39 character IPv6 structure. For IPv4 mapped IPv6 addresses, the string can be longer (than 39 characters). An example to show this:
IPv6 (39 characters) :
ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:ABCD
IPv4-mapped IPv6 (45 characters) :
ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:192.168.158.190
Note: the last 32-bits (that correspond to IPv4 address) can need up to 15 characters (as IPv4 uses 4 groups of 1 byte and is formatted as 4 decimal numbers in the range 0-255 separated by dots (the .
character), so the maximum is DDD.DDD.DDD.DDD
).
The correct maximum IPv6 string length, therefore, is 45.
This was actually a quiz question in an IPv6 training I attended. (We all answered 39!)
It seems like you installed a zip version of sbt, which is fine. But I suggest you install the native debian package if you are on Ubuntu. That is how I managed to install it on my Ubuntu 12.04. Check it out here: http://www.scala-sbt.org/release/docs/Installing-sbt-on-Linux.html Or simply directly download it from here.
It is possible to insert an image in a Google Spreadsheet using Google Apps Script. However, the image should have been hosted publicly over internet. At present, it is not possible to insert private images from Google Drive.
You can use following code to insert an image through script.
function insertImageOnSpreadsheet() {
var SPREADSHEET_URL = 'INSERT_SPREADSHEET_URL_HERE';
// Name of the specific sheet in the spreadsheet.
var SHEET_NAME = 'INSERT_SHEET_NAME_HERE';
var ss = SpreadsheetApp.openByUrl(SPREADSHEET_URL);
var sheet = ss.getSheetByName(SHEET_NAME);
var response = UrlFetchApp.fetch(
'https://developers.google.com/adwords/scripts/images/reports.png');
var binaryData = response.getContent();
// Insert the image in cell A1.
var blob = Utilities.newBlob(binaryData, 'image/png', 'MyImageName');
sheet.insertImage(blob, 1, 1);
}
Above example has been copied from this link. Check noogui's reply for details.
In case you need to insert image from Google Drive, please check this link for current updates.
You can't change the margin of a table cell. But you CAN change the padding. Change the padding of the TD, which will make the cell larger and push the text away from the side with the increased padding. If you have border lines, however, it still won't be exactly what you want.
The problem is that IE won't reset the proxy settings until it either

int age = new DateTime(timeSpan.Ticks).Year - 1;
I had a specific requirement to do something similar where it would show month-year which can be done by the following:
SELECT DATENAME(month, GETDATE()) + '-' + CAST(YEAR(GETDATE()) AS nvarchar) AS 'Month-Year'
In my particular case, I needed to have it down to the 3 letter month abreviation with a 2 digit year, looking something like this:
SELECT LEFT(DATENAME(month, GETDATE()), 3) + '-' + CAST(RIGHT(YEAR(GETDATE()),2) AS nvarchar(2)) AS 'Month-Year'
finish() method is used to finish the activity and remove it from back stack. You can call it in any method in activity. But make sure you close all the Database connections, all reference variables null to prevent any memory leaks.
If the image has big dimenssions is hard to get good results without resizing, below is a 60 percent resizing which for most of the purposes doesn't destroys too much of the image.
I use this with good result for gray-scale images (I convert from PNG):
ls ./*.png | xargs -L1 -I {} convert {} -strip -interlace JPEG -sampling-factor 4:2:0 -adaptive-resize 60% -gaussian-blur 0.05 -colorspace Gray -quality 20 {}.jpg
I use this for scanned B&W pages get them to gray-scale images (the extra arguments cleans shadows from previous pages):
ls ./*.png | xargs -L1 -I {} convert {} -strip -interlace JPEG -sampling-factor 4:2:0 -adaptive-resize 60% -gaussian-blur 0.05 -colorspace Gray -quality 20 -density 300 -fill white -fuzz 40% +opaque "#000000" -density 300 {}.jpg
I use this for color images:
ls ./*.png | xargs -L1 -I {} convert {} -strip -interlace JPEG -sampling-factor 4:2:0 -adaptive-resize 60% -gaussian-blur 0.05 -colorspace RGB -quality 20 {}.jpg
Just check for it before you pass to your function. So you would pass:
thing.foo ? thing.foo.bar : undefined
As mentioned in other answers ORDER BY 1
orders by the first column.
I came across another example of where you might use it though. We have certain queries which need to be ordered select the same column. You would get a SQL error if ordering by Name
in the below.
SELECT Name, Name FROM Segment ORDER BY 1
Here's my current implementation:
$.liveClickHold = function(selector, fn) {
$(selector).live("mousedown", function(evt) {
var $this = $(this).data("mousedown", true);
setTimeout(function() {
if ($this.data("mousedown") === true) {
fn(evt);
}
}, 500);
});
$(selector).live("mouseup", function(evt) {
$(this).data("mousedown", false);
});
}
If you're using Mongoose, the only way to be sure to have the id as an hex String seems to be:
object._id ? object._id.toHexString():object.toHexString();
This is because object._id exists only if the object is populated, if not the object is an ObjectId
For Development you can also deactivate the browser cache - In Chrome Dev Tools on the bottom right click on the gear and tick the option
Disable cache (while DevTools is open)
Update: In Firefox there is the same option in Debugger -> Settings -> Advanced Section (checked for Version 33)
Update 2: Although this option appears in Firefox some report it doesn't work. I suggest using firebug and following hadaytullah answer.
As stated in one other answer Docker doesn't play nice with a VPN. If you're using Nordvpn you have to disable "Invisibility on LAN" and probably "Internet Kill Switch".
If you've done so it should work even with the VPN active.
I see that this question is very old, but this is the solution I used for the same problem, and it seems to require a bit less code than the others.
As @Maloric mentioned in his answer to this question:
var jo = JObject.Parse(myJsonString);
To use JObject, you need the following in your class file
using Newtonsoft.Json.Linq;
HTML:
<button onclick="scrollToTop(1000);"></button>
1# JavaScript (linear):
function scrollToTop (duration) {
// cancel if already on top
if (document.scrollingElement.scrollTop === 0) return;
const totalScrollDistance = document.scrollingElement.scrollTop;
let scrollY = totalScrollDistance, oldTimestamp = null;
function step (newTimestamp) {
if (oldTimestamp !== null) {
// if duration is 0 scrollY will be -Infinity
scrollY -= totalScrollDistance * (newTimestamp - oldTimestamp) / duration;
if (scrollY <= 0) return document.scrollingElement.scrollTop = 0;
document.scrollingElement.scrollTop = scrollY;
}
oldTimestamp = newTimestamp;
window.requestAnimationFrame(step);
}
window.requestAnimationFrame(step);
}
2# JavaScript (ease in and out):
function scrollToTop (duration) {
// cancel if already on top
if (document.scrollingElement.scrollTop === 0) return;
const cosParameter = document.scrollingElement.scrollTop / 2;
let scrollCount = 0, oldTimestamp = null;
function step (newTimestamp) {
if (oldTimestamp !== null) {
// if duration is 0 scrollCount will be Infinity
scrollCount += Math.PI * (newTimestamp - oldTimestamp) / duration;
if (scrollCount >= Math.PI) return document.scrollingElement.scrollTop = 0;
document.scrollingElement.scrollTop = cosParameter + cosParameter * Math.cos(scrollCount);
}
oldTimestamp = newTimestamp;
window.requestAnimationFrame(step);
}
window.requestAnimationFrame(step);
}
/*
Explanation:
- pi is the length/end point of the cosinus intervall (see below)
- newTimestamp indicates the current time when callbacks queued by requestAnimationFrame begin to fire.
(for more information see https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame)
- newTimestamp - oldTimestamp equals the delta time
a * cos (bx + c) + d | c translates along the x axis = 0
= a * cos (bx) + d | d translates along the y axis = 1 -> only positive y values
= a * cos (bx) + 1 | a stretches along the y axis = cosParameter = window.scrollY / 2
= cosParameter + cosParameter * (cos bx) | b stretches along the x axis = scrollCount = Math.PI / (scrollDuration / (newTimestamp - oldTimestamp))
= cosParameter + cosParameter * (cos scrollCount * x)

The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:
RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);
There, &rect
is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.
The code should create a dynamic variable:
RectInvoice *rect = new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);
There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.
Cheers
Do you really need to load it from a file? If you place it along your classes (in WEB-INF/classes) you can get an InputStream to it using the class loader:
InputStream csv =
SomeClassInTheSamePackage.class.getResourceAsStream("filename.csv");
You need to add logic to assign random values to double[] array using randomFill method.
Change
public static double[] list(){
anArray = new double[10];
return anArray;
}
To
public static double[] list() {
anArray = new double[10];
for(int i=0;i<anArray.length;i++)
{
anArray[i] = randomFill();
}
return anArray;
}
Then you can call methods, including list() and print() in main method to generate random double values and print the double[] array in console.
public static void main(String args[]) {
list();
print();
}
One result is as follows:
-2.89783865E8
1.605018025E9
-1.55668528E9
-1.589135498E9

On Arch Linux you can install ncurses5-compat-libs
AUR package.
FYI it is mentioned in Arch Wiki android page, just in case if you'll need some other dependencies for Android Studio: https://wiki.archlinux.org/index.php/Android
Download and Install your device driver manually through visiting manufacturer website like :Samsung,micromax,intex etc.
Java didn't provide multiple inheritance.
When you say A extends B then it means that A extends B and B extends Object.
It doesn't mean A extends B, Object.
class A extends Object
class B extends A
Well, I believe the question is answered and has already been accepted. But I am going to write what I faced and how I solved it.
I did receive also the same error:
Error:Execution failed for task ':app:transformClassesWithDexForDebug'. com.android.build.api.transform.TransformException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_60\bin\java.exe'' finished with non-zero exit value 1
I wasn't fortunate to apply all the settings and got success. But when I tried to Debug the project again. This time I got Three Error (including above):
Error:Java HotSpot(TM) 64-Bit Server VM warning: CodeCache is full. Compiler has been disabled.
and
Error:Java HotSpot(TM) 64-Bit Server VM warning: Try increasing the code cache size using -XX:ReservedCodeCacheSize=
So what I did? I just go to Android Studio:
File > Invalidate Caches / Restart.. > Invalidate & Restart
Quick Fix!
Extra Note:
What I found in Gradle Console:
:app:incrementalDebugTasks :app:prePackageMarkerForDebug :app:fastDeployDebugExtractor :app:generateDebugInstantRunAppInfo :app:transformClassesWithDexForDebug To run dex in process, the Gradle daemon needs a larger heap. It currently has approximately 910 MB. For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB. To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties. For more information see https://docs.gradle.org/current/userguide/build_environment.html :app:transformClassesWithDexForDebug FAILED

Simply create a folder named "data" in C drive and inside data folder create another folder named "db". Then execute mongod.exe :)
You can use row_number()
to get the row number of the row. It uses the over
command - the partition by
clause specifies when to restart the numbering and the order by
selects what to order the row number on. Even if you added an order by
to the end of your query, it would preserve the ordering in the over
command when numbering.
select *
from mytable
where row_number() over(partition by Name order by AddressLine) = 1
The answers about using select()
/poll()
are right and code should be written this way to be portable.
However, since you're on Linux, you can do this:
int synRetries = 2; // Send a total of 3 SYN packets => Timeout ~7s
setsockopt(fd, IPPROTO_TCP, TCP_SYNCNT, &synRetries, sizeof(synRetries));
See man 7 tcp
and man setsockopt
.
I used this to speed up the connect-timeout in a program I needed to patch quickly. Hacking it to timeout via select()
/poll()
was not an option.
In my case, IIS was fine but.. uh.. all the files in the folder except web.config had been deleted (a manual deployment half-done on a test site).
I've just tested the following in Chrome (79), Firefox (71) and Edge (44) and it works fine. It applies the script solution as others noted above.
Just add a "Logout" link and when clicked return the following html
<div>You have been logged out. Redirecting to home...</div>
<script>
var XHR = new XMLHttpRequest();
XHR.open("GET", "/Home/MyProtectedPage", true, "no user", "no password");
XHR.send();
setTimeout(function () {
window.location.href = "/";
}, 3000);
</script>
The problem is that, even though your phone is rooted, the 'adbd' server on the phone does not use root permissions. You can try to bypass these checks or install a different adbd on your phone or install a custom kernel/distribution that includes a patched adbd.
Or, a much easier solution is to use 'adbd insecure' from chainfire which will patch your adbd on the fly. It's not permanent, so you have to run it before starting up the adb server (or else set it to run every boot). You can get the app from the google play store for a couple bucks:
https://play.google.com/store/apps/details?id=eu.chainfire.adbd&hl=en
Or you can get it for free, the author has posted a free version on xda-developers:
http://forum.xda-developers.com/showthread.php?t=1687590
Install it to your device (copy it to the device and open the apk file with a file manager), run adb insecure
on the device, and finally kill the adb server on your computer:
% adb kill-server
And then restart the server and it should already be root.
Create a UIImageView and add UIImage to it:
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image Name"]] ;
Then add it to your view:
[self.view addSubView: imageView];
There is also this tool you can use. It supports multi-events .ics file creation. It also supports timezone as well.

This is correct query for join 3 table with same id**
select a.empname,a.empsalary,b.workstatus,b.bonus,c.dateofbirth from employee a, Report b,birth c where a.empid=b.empid and a.empid=c.empid and b.empid='103';
employee first table. report second table. birth third table
var items = [
{"id":"88","name":"Lets go testing"},
{"id":"99","name":"Have fun boys and girls"},
{"id":"108","name":"You are awesome!"}
];
If you are using jQuery, use jQuery.grep like this:
items = $.grep(items, function(item) {
return item.id !== '88';
});
// items => [{ id: "99" }, { id: "108" }]
Using ES5 Array.prototype.filter:
items = items.filter(function(item) {
return item.id !== '88';
});
// items => [{ id: "99" }, { id: "108" }]
Will something like this work for you?
>>> def namestr(**kwargs):
... for k,v in kwargs.items():
... print "%s = %s" % (k, repr(v))
...
>>> namestr(a=1, b=2)
a = 1
b = 2
And in your example:
>>> choice = {'key': 24; 'data': None}
>>> namestr(choice=choice)
choice = {'data': None, 'key': 24}
>>> printvars(**globals())
__builtins__ = <module '__builtin__' (built-in)>
__name__ = '__main__'
__doc__ = None
namestr = <function namestr at 0xb7d8ec34>
choice = {'data': None, 'key': 24}
There are quite number of tools available for viewing large files. http://download.cnet.com/Large-Text-File-Viewer/3000-2379_4-90541.html This for instance. However, I was successful with larger files viewing in Visual studio. Thought it took some time to load, it worked.
You can change the comment character to something besides # like this:
git config --global core.commentchar "@"
const absolutePath = path.join(__dirname, some, dir);
vs.
const absolutePath = path.resolve(__dirname, some, dir);
path.join
will concatenate __dirname
which is the directory name of the current file concatenated with values of some
and dir
with platform-specific separator.
Whereas
path.resolve
will process __dirname
, some
and dir
i.e. from right to left prepending it by processing it.
If any of the values of some
or dir
corresponds to a root path then the previous path will be omitted and process rest by considering it as root
In order to better understand the concept let me explain both a little bit more detail as follows:-
The path.join
and path.resolve
are two different methods or functions of the path module provided by nodejs.
Where both accept a list of paths but the difference comes in the result i.e. how they process these paths.
path.join
concatenates all given path segments together using the platform-specific separator as a delimiter, then normalizes the resulting path. While the path.resolve()
process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.
When no arguments supplied
The following example will help you to clearly understand both concepts:-
My filename is index.js
and the current working directory is E:\MyFolder\Pjtz\node
const path = require('path');
console.log("path.join() : ", path.join());
// outputs .
console.log("path.resolve() : ", path.resolve());
// outputs current directory or equivalent to __dirname
Result
? node index.js
path.join() : .
path.resolve() : E:\MyFolder\Pjtz\node
path.resolve()
method will output the absolute path whereas the path.join()
returns . representing the current working directory if nothing is provided
When some root path is passed as arguments
const path=require('path');
console.log("path.join() : " ,path.join('abc','/bcd'));
console.log("path.resolve() : ",path.resolve('abc','/bcd'));
Result i
? node index.js
path.join() : abc\bcd
path.resolve() : E:\bcd
path.join()
only concatenates the input list with platform-specific separator while the path.resolve()
process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.
Update: If you are using CLion 2020.2, then it already supports Makefiles. If you are using an older version, read on.
Even though currently only CMake is supported, you can instruct CMake to call make
with your custom Makefile
. Edit your CMakeLists.txt
adding one of these two commands:
When you tell CLion
to run your program, it will try to find an executable with the same name of the target in the directory pointed by PROJECT_BINARY_DIR
. So as long as your make
generates the file where CLion
expects, there will be no problem.
Here is a working example:
CLion
to pass its $(PROJECT_BINARY_DIR) to make
This is the sample CMakeLists.txt
:
cmake_minimum_required(VERSION 2.8.4)
project(mytest)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
add_custom_target(mytest COMMAND make -C ${mytest_SOURCE_DIR}
CLION_EXE_DIR=${PROJECT_BINARY_DIR})
CLion's
directoryThis is the sample Makefile
:
all:
echo Compiling $(CLION_EXE_DIR)/$@ ...
g++ mytest.cpp -o $(CLION_EXE_DIR)/mytest
That is all, you may also want to change your program's working directory so it executes as it is when you run make from inside your directory. For this edit: Run -> Edit Configurations ... -> mytest -> Working directory
You can call a service from your controller that returns a promise and then use it in your controller. And further use $emit
or $broadcast
to inform other controllers about it.
In my case, I had to make http calls through my service, so I did something like this :
function ParentController($scope, testService) {
testService.getList()
.then(function(data) {
$scope.list = testService.list;
})
.finally(function() {
$scope.$emit('listFetched');
})
function ChildController($scope, testService) {
$scope.$on('listFetched', function(event, data) {
// use the data accordingly
})
}
and my service looks like this
app.service('testService', ['$http', function($http) {
this.list = [];
this.getList = function() {
return $http.get(someUrl)
.then(function(response) {
if (typeof response.data === 'object') {
list = response.data.results;
return response.data;
} else {
// invalid response
return $q.reject(response.data);
}
}, function(response) {
// something went wrong
return $q.reject(response.data);
});
}
}])
I agree with @haha on this one, for the most part. But there are several cross-browser related issues with using the "float:right" and could ultimately give you more of a headache than you want. If you know what the widths are going to be for each column use a float:left on both and save yourself the trouble. Another thing you can incorporate into your methodology is build column classes into your CSS.
So try something like this:
CSS
.col-wrapper{width:960px; margin:0 auto;}
.col{margin:0 10px; float:left; display:inline;}
.col-670{width:670px;}
.col-250{width:250px;}
HTML
<div class="col-wrapper">
<div class="col col-670">[Page Content]</div>
<div class="col col-250">[Page Sidebar]</div>
</div>
window.location.reload()
will reload from the server and will load all your data, scripts, images, etc. again.
So if you just want to refresh the HTML, the window.location = document.URL
will return much quicker and with less traffic. But it will not reload the page if there is a hash (#) in the URL.
Check if IIS Express is installed. If IIS Express is missing, Visual Studio might discard the setting <UseIISExpress>false</UseIISExpress>
and still look for the express.
Simply Abstract Data Type is nothing but a set of operation and set of data is used for storing some other data efficiently in the machine. There is no need of any perticular type declaration. It just require a implementation of ADT.

As you've figured out, Entity Framework can't actually run your C# code as part of its query. It has to be able to convert the query to an actual SQL statement. In order for that to work, you will have to restructure your query expression into an expression that Entity Framework can handle.

What you want to do is referred to as "squashing" in git. There are lots of options when you're doing this (too many?) but if you just want to merge all of your unpushed commits into a single commit, do this:
git rebase -i origin/master
This will bring up your text editor (-i
is for "interactive") with a file that looks like this:
pick 16b5fcc Code in, tests not passing
pick c964dea Getting closer
pick 06cf8ee Something changed
pick 396b4a3 Tests pass
pick 9be7fdb Better comments
pick 7dba9cb All done
Change all the pick
to squash
(or s
) except the first one:
pick 16b5fcc Code in, tests not passing
squash c964dea Getting closer
squash 06cf8ee Something changed
squash 396b4a3 Tests pass
squash 9be7fdb Better comments
squash 7dba9cb All done
Save your file and exit your editor. Then another text editor will open to let you combine the commit messages from all of the commits into one big commit message.
Voila! Googling "git squashing" will give you explanations of all the other options available.
You can use DataColumn.Ordinal
to get the index of the column in the DataTable
. So if you need the next column as mentioned use Column.Ordinal + 1
:
row[row.Table.Columns["ColumnName"].Ordinal + 1] = someOtherValue;
This happens because your click
handler fires before the value of the radio button changes. You need to listen to the change
event instead:
<input
type="radio"
name="optionsRadios"
id="optionsRadios2"
value=""
v-model="srStatus"
v-on:change="foo"> //here
Also, make sure you really want to call foo()
on ready... seems like maybe you don't actually want to do that.
ready:function(){
foo();
},
How about this compact little trick?
var possible = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
var stringLength = 5;
function pickRandom() {
return possible[Math.floor(Math.random() * possible.length)];
}
var randomString = Array.apply(null, Array(stringLength)).map(pickRandom).join('');
You need the Array.apply
there to trick the empty array into being an array of undefineds.
If you're coding for ES2015, then building the array is a little simpler:
var randomString = Array.from({ length: stringLength }, pickRandom).join('');
Try setting a height on your td elements.
vertical-align: middle;
means the element the style is applied to will be aligned within the parent element. The height of the td may be only as high as the text inside.
Float right the text you want to appear on the right, and in the markup make sure that this text and its surrounding span occurs before the text that should be on the left. If it doesn't occur first, you may have problems with the floated text appearing on a different line.
<html>
<body>
<div>
<span style="float:right">here</span>Lorem Ipsum etc<br/>
blah<br/>
blah blah<br/>
blah<br/>
<span style="float:right">and here</span>lorem ipsums<br/>
</div>
</body>
</html>
Note that this works for any line, not just the top and bottom corners.
Try word.matches("^[0-9,;]+$");
Add a runtime first and select project properties. Then check the server name from the 'Runtimes' tab as shown in the image.
To see what the problem is, when you get the cryptic error 0 go to ... | More Tools | Developer Tools (Ctrl+Shift+I) in Chrome (on the page giving the error)
Read the red text in the log to get the true error message. If there is too much in there, right-click and Clear Console, then do your last request again.
My first problem was, I was passing in Authorization headers to my own cross-domain web service for the browser for the first time.
I already had:
Access-Control-Allow-Origin: *
But not:
Access-Control-Allow-Methods: GET, POST, PUT, DELETE
Access-Control-Allow-Headers: Authorization
in the response header of my web service.
After I added that, my error zero was gone from my own web server, as well as when running the index.html file locally without a web server, but was still giving errors in code pen.
Back to ... | More Tools | Developer Tools while getting the error in codepen, and there is clearly explained: codepen uses https, so I cannot make calls to http, as the security is lower.
I need to therefore host my web service on https.
Knowing how to get the true error message - priceless!
On Ubuntu, this can also be caused by incorrect permissions. I chmod 755 Logs/
which fixed the issue.
1752 was the year of Britain switching from the Julian to the Gregorian calendar. I believe two weeks in September 1752 never happened as a result, which has implications for dates in that general area.
An explanation: http://uneasysilence.com/archive/2007/08/12008/ (Internet Archive version)
forget about adding the permission into the manifest Add this code as a method
public static boolean hasPermissions(Context context, String... permissions)
{
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null)
{
for (String permission : permissions)
{
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED)
{
return false;
}
}
}
return true;
}
and write this in your Main

String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_SMS, Manifest.permission.CAMERA};

My question is: Why is not calling
return
faster
It’s faster because return
is a (primitive) function in R, which means that using it in code incurs the cost of a function call. Compare this to most other programming languages, where return
is a keyword, but not a function call: it doesn’t translate to any runtime code execution.
That said, calling a primitive function in this way is pretty fast in R, and calling return
incurs a minuscule overhead. This isn’t the argument for omitting return
.
or better, and thus preferable?
Because there’s no reason to use it.
Because it’s redundant, and it doesn’t add useful redundancy.
To be clear: redundancy can sometimes be useful. But most redundancy isn’t of this kind. Instead, it’s of the kind that adds visual clutter without adding information: it’s the programming equivalent of a filler word or chartjunk).
Consider the following example of an explanatory comment, which is universally recognised as bad redundancy because the comment merely paraphrases what the code already expresses:
# Add one to the result
result = x + 1
Using return
in R falls in the same category, because R is a functional programming language, and in R every function call has a value. This is a fundamental property of R. And once you see R code from the perspective that every expression (including every function call) has a value, the question then becomes: “why should I use return
?” There needs to be a positive reason, since the default is not to use it.
One such positive reason is to signal early exit from a function, say in a guard clause:
f = function (a, b) {
if (! precondition(a)) return() # same as `return(NULL)`!
calculation(b)
}
This is a valid, non-redundant use of return
. However, such guard clauses are rare in R compared to other languages, and since every expression has a value, a regular if
does not require return
:
sign = function (num) {
if (num > 0) {
1
} else if (num < 0) {
-1
} else {
0
}
}
We can even rewrite f
like this:
f = function (a, b) {
if (precondition(a)) calculation(b)
}
… where if (cond) expr
is the same as if (cond) expr else NULL
.
Finally, I’d like to forestall three common objections:
Some people argue that using return
adds clarity, because it signals “this function returns a value”. But as explained above, every function returns something in R. Thinking of return
as a marker of returning a value isn’t just redundant, it’s actively misleading.
Relatedly, the Zen of Python has a marvellous guideline that should always be followed:
Explicit is better than implicit.
How does dropping redundant return
not violate this? Because the return value of a function in a functional language is always explicit: it’s its last expression. This is again the same argument about explicitness vs redundancy.
In fact, if you want explicitness, use it to highlight the exception to the rule: mark functions that don’t return a meaningful value, which are only called for their side-effects (such as cat
). Except R has a better marker than return
for this case: invisible
. For instance, I would write
save_results = function (results, file) {
# … code that writes the results to a file …
invisible()
}
But what about long functions? Won’t it be easy to lose track of what is being returned?
Two answers: first, not really. The rule is clear: the last expression of a function is its value. There’s nothing to keep track of.
But more importantly, the problem in long functions isn’t the lack of explicit return
markers. It’s the length of the function. Long functions almost (?) always violate the single responsibility principle and even when they don’t they will benefit from being broken apart for readability.
>>> d = {}
>>> D = set()
>>> type(d)
<type 'dict'>
>>> type(D)
<type 'set'>
What you've made is a dictionary and not a Set.
The update
method in dictionary is used to update the new dictionary from a previous one, like so,
>>> abc = {1: 2}
>>> d.update(abc)
>>> d
{1: 2}
Whereas in sets, it is used to add elements to the set.
>>> D.update([1, 2])
>>> D
set([1, 2])
If you are not validating explicitly for numbers in the text field, in any case its better to use
int result=0;
if(int.TryParse(textBox1.Text,out result))
Now if the result is success then you can proceed with your calculations.

I think your best bet would be to use a combination of absolute and relative positioning.
Here's a fiddle: http://jsfiddle.net/PKVza/2/
given your html:
<div class="row">
<div class="col-sm-6">
<img src="~/Images/MyLogo.png" alt="Logo" />
</div>
<div class="bottom-align-text col-sm-6">
<h3>Some Text</h3>
</div>
</div>
use the following CSS:
@media (min-width: 768px ) {
.row {
position: relative;
}
.bottom-align-text {
position: absolute;
bottom: 0;
right: 0;
}
}
EDIT - Fixed CSS and JSFiddle for mobile responsiveness and changed the ID to a class.
As the official documentation says:
body - entity body for PATCH, POST and PUT requests. Must be a Buffer, String or ReadStream. If json is true, then body must be a JSON-serializable object.
When sending JSON you just have to put it in body of the option.
var options = {
uri: 'https://myurl.com',
method: 'POST',
json: true,
body: {'my_date' : 'json'}
}
request(options, myCallback)
For HTTP:
<bindings>
<basicHttpBinding>
<binding name="basicHttp" allowCookies="true"
maxReceivedMessageSize="20000000"
maxBufferSize="20000000"
maxBufferPoolSize="20000000">
<readerQuotas maxDepth="200"
maxArrayLength="200000000"
maxBytesPerRead="4096"
maxStringContentLength="200000000"
maxNameTableCharCount="16384"/>
</binding>
</basicHttpBinding>
</bindings>
For TCP:
<bindings>
<netTcpBinding>
<binding name="tcpBinding"
maxReceivedMessageSize="20000000"
maxBufferSize="20000000"
maxBufferPoolSize="20000000">
<readerQuotas maxDepth="200"
maxArrayLength="200000000"
maxStringContentLength="200000000"
maxBytesPerRead="4096"
maxNameTableCharCount="16384"/>
</binding>
</netTcpBinding>
</bindings>
IMPORTANT:
If you try to pass complex object that has many connected objects (e.g: a tree data structure, a list that has many objects...), the communication will fail no matter how you increased the Quotas. In such cases, you must increase the containing objects count:
<behaviors>
<serviceBehaviors>
<behavior name="NewBehavior">
...
<dataContractSerializer maxItemsInObjectGraph="2147483646"/>
</behavior>
</serviceBehaviors>

I just wanted to use the import
and export
in JavaScript files.
Everyone says it's not possible. But, as of May 2018, it's possible to use above in plain Node.js, without any modules like Babel, etc.
Here is a simple way to do it.
Create the below files, run, and see the output for yourself.
Also don't forget to see Explanation
below.
function myFunc() {
console.log("Hello from myFunc")
}
export default myFunc;
import myFunc from "./myfile.mjs" // Simply using "./myfile" may not work in all resolvers
myFunc();
node --experimental-modules index.mjs
(node:12020) ExperimentalWarning: The ESM module loader is experimental.
Hello from myFunc
Explanation:
--experimental-modules
to the node index.mjs
node --version
, it gives me "v10.3.0", though the LTE/stable/recommended version is 8.11.2 LTS.Here is what worked for me:
If you are installing on a 64-bit machine, make sure the application properties under the Build tab have "Any CPU" as the platform target, and unselect the check box for "Prefer 32-bit" if you have the option. Crystal is very touchy about 32/64 bit assemblies, and makes some pretty counterintuitive assumptions which are very difficult to troubleshoot.
use numberOfLines
https://rnplay.org/plays/ImmKkA/edit
or if you know/or can compute the max character count per row, JS substring may be used.
<Text>{ ((mytextvar).length > maxlimit) ?
(((mytextvar).substring(0,maxlimit-3)) + '...') :
mytextvar }
</Text>
Use a list instead and replace your foreach
loop with a for
loop:
@model IList<BlockedIPViewModel>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@for (var i = 0; i < Model.Count; i++)
{
<tr>
<td>
@Html.HiddenFor(x => x[i].IP)
@Html.CheckBoxFor(x => x[i].Checked)
</td>
<td>
@Html.DisplayFor(x => x[i].IP)
</td>
</tr>
}
<div>
<input type="submit" value="Unblock IPs" />
</div>
}
Alternatively you could use an editor template:
@model IEnumerable<BlockedIPViewModel>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.EditorForModel()
<div>
<input type="submit" value="Unblock IPs" />
</div>
}
and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml
which will automatically be rendered for each element of the collection:
@model BlockedIPViewModel
<tr>
<td>
@Html.HiddenFor(x => x.IP)
@Html.CheckBoxFor(x => x.Checked)
</td>
<td>
@Html.DisplayFor(x => x.IP)
</td>
</tr>
The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article
.
Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.
I've used this "portable plotter". It's very small, multiplatform, easy to use and you can plug it into different graphical libraries. pplot
(Only for the plots part)
If you use or plan to use Qt, another multiplatform solution is Qwt and Qchart
If you are using Python3.
then you can use Print Function :
your_data = {"Purchase Amount": 'TotalAmount'}
print(your_data, file=open('D:\log.txt', 'w'))
For python2
this is the example of Python Print String To Text File
def my_func():
"""
this function return some value
:return:
"""
return 25.256
def write_file(data):
"""
this function write data to file
:param data:
:return:
"""
file_name = r'D:\log.txt'
with open(file_name, 'w') as x_file:
x_file.write('{} TotalAmount'.format(data))
def run():
data = my_func()
write_file(data)
run()
Just a friendly reminder if you have files locally that aren't in github and yet your git status
says
Your branch is up to date with 'origin/master'. nothing to commit, working tree clean
It can happen if the files are in .gitignore
Try running
cat .gitignore
and seeing if these files show up there. That would explain why git doesn't want to move them to the remote.
For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.
The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)
Using this regex:
^(?!.*function).*(\&\$)
it is possible to search project-wide for the occurrence of &$
only in lines that are not a function definition.
This still turns up a lot of false positives, but it does make the job easier.
VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.
I couldn't find any exact and valid way to do this. So after a whole day, I came with this mixed code achieved from different sources and trying to get the job done.
But it is still generating an exception ExecuteNonQuery: CommandText property has not been Initialized
even though it successfully runs the script file - in my case, it successfully creates the database and inserts data on the first startup.

What you have is correct, but this is more consice:
^[A-Z]{3}$
$files = [
'./first.jpg',
'./second.jpg',
'./third.jpg'
];
foreach ($files as $file) {
if (file_exists($file)) {
unlink($file);
} else {
// File not found.
}
}
The correct answer is already given, nevertheless here is the better way (than switch):
private Dictionary<Operator, Func<int, int, double>> operators =
new Dictionary<Operator, Func<int, int, double>>
{
{ Operator.PLUS, ( a, b ) => a + b },
{ Operator.MINUS, ( a, b ) => a - b },
{ Operator.MULTIPLY, ( a, b ) => a * b },
{ Operator.DIVIDE ( a, b ) => (double)a / b },
};
public double Calculate( int left, int right, Operator op )
{
return operators.ContainsKey( op ) ? operators[ op ]( left, right ) : 0.0;
}
It looks to me like Windows 8 and IIS 7 no longer provides any UI to create a user name and password for basic authentication that is NOT a windows local user account. It is clearly a superior approach to create an IIS-only user/password authentication pair, but it is not clear and easy how it is done.
Command line tools exist for this purpose. Some people create a Windows account and then remove the Log on Locally User Privilege.
The LockedOut
property is what you are looking for among all the properties you returned. You are only seeing incomplete output in TechNet. The information is still there. You can isolate that one property using Select-Object
Get-ADUser matt -Properties * | Select-Object LockedOut
LockedOut
---------
False
The link you referenced doesn't contain this information which is obviously misleading. Test the command with your own account and you will see much more information.
Note: Try to avoid -Properties *
. While it is great for simple testing it can make queries, especially ones with multiple accounts, unnecessarily slow. So, in this case, since you only need lockedout
:
Get-ADUser matt -Properties LockedOut | Select-Object LockedOut
Displaying an Image
in WPF is much easier than that. Try this:
<Image Source="{Binding DisplayedImagePath}" HorizontalAlignment="Left"
Margin="0,0,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Bottom"
Grid.Row="8" Width="200" Grid.ColumnSpan="2" />
And the property can just be a string
:
public string DisplayedImage
{
get { return @"C:\Users\Public\Pictures\Sample Pictures\Chrysanthemum.jpg"; }
}
Although you really should add your images to a folder named Images
in the root of your project and set their Build Action to Resource in the Properties Window in Visual Studio... you could then access them using this format:
public string DisplayedImage
{
get { return "/AssemblyName;component/Images/ImageName.jpg"; }
}
UPDATE >>>
As a final tip... if you ever have a problem with a control not working as expected, simply type 'WPF', the name of that control and then the word 'class' into a search engine. In this case, you would have typed 'WPF Image Class'. The top result will always be MSDN and if you click on the link, you'll find out all about that control and most pages have code examples as well.
UPDATE 2 >>>
If you followed the examples from the link to MSDN and it's not working, then your problem is not the Image
control. Using the string
property that I suggested, try this:
<StackPanel>
<Image Source="{Binding DisplayedImagePath}" />
<TextBlock Text="{Binding DisplayedImagePath}" />
</StackPanel>
If you can't see the file path in the TextBlock
, then you probably haven't set your DataContext
to the instance of your view model. If you can see the text, then the problem is with your file path.
UPDATE 3 >>>
In .NET 4, the above Image.Source
values would work. However, Microsoft made some horrible changes in .NET 4.5 that broke many different things and so in .NET 4.5, you'd need to use the full pack
path like this:
<Image Source="pack://application:,,,/AssemblyName;component/Images/image_to_use.png">
For further information on pack URIs, please see the Pack URIs in WPF page on Microsoft Docs.
If you are on Windows, you can use the CreateThreadpoolTimer function to schedule a callback without needing to worry about thread management and without blocking the current thread.
template<typename T>
static void __stdcall timer_fired(PTP_CALLBACK_INSTANCE, PVOID context, PTP_TIMER timer)
{
CloseThreadpoolTimer(timer);
std::unique_ptr<T> callable(reinterpret_cast<T*>(context));
(*callable)();
}
template <typename T>
void call_after(T callable, long long delayInMs)
{
auto state = std::make_unique<T>(std::move(callable));
auto timer = CreateThreadpoolTimer(timer_fired<T>, state.get(), nullptr);
if (!timer)
{
throw std::runtime_error("Timer");
}
ULARGE_INTEGER due;
due.QuadPart = static_cast<ULONGLONG>(-(delayInMs * 10000LL));
FILETIME ft;
ft.dwHighDateTime = due.HighPart;
ft.dwLowDateTime = due.LowPart;
SetThreadpoolTimer(timer, &ft, 0 /*msPeriod*/, 0 /*msWindowLength*/);
state.release();
}
int main()
{
auto callback = []
{
std::cout << "in callback\n";
};
call_after(callback, 1000);
std::cin.get();
}
Lots of options here, but one of the easiest to follow is subset
. Consider:

>
> subset(df, date > 5 & date < 15)

You can also insert logic directly into the index for your data.frame. The comma separates the rows from columns. We just have to remember that R indexes rows first, then columns. So here we are saying rows with date > 5 & < 15 and then all columns:
df[df$date > 5 & df$date < 15 ,]
I'd also recommend checking out the help pages for subset, ?subset
and the logical operators ?"&"
If you're calling ProgressDialog.show() in a fragment, casting the mContext to Activity worked for me.
ProgressDialog pd = new ProgressDialog((Activity) mContext);
I’m surprised no-one answered with this code:
for(var child=elt.firstChild;
child;
child=child.nextSibling){
do_thing(child);
}
Or, if you only want children which are elements, this code:
for(var child=elt.firstElementChild;
child;
child=child.nextElementSibling){
do_thing(child);
}
A case when process get SIGABRT from itself: Hrvoje mentioned about a buried pure virtual being called from ctor generating an abort, i recreated an example for this. Here when d is to be constructed, it first calls its base class A ctor, and passes inside pointer to itself. the A ctor calls pure virtual method before table was filled with valid pointer, because d is not constructed yet.
#include<iostream>
using namespace std;
class A {
public:
A(A *pa){pa->f();}
virtual void f()=0;
};
class D : public A {
public:
D():A(this){}
virtual void f() {cout<<"D::f\n";}
};
int main(){
D d;
A *pa = &d;
pa->f();
return 0;
}
compile: g++ -o aa aa.cpp
ulimit -c unlimited
run: ./aa
pure virtual method called
terminate called without an active exception
Aborted (core dumped)
now lets quickly see the core file, and validate that SIGABRT was indeed called:
gdb aa core
see regs:
i r
rdx 0x6 6
rsi 0x69a 1690
rdi 0x69a 1690
rip 0x7feae3170c37
check code:

I just developed a javascript library called JIC to solve that problem. It allows you to compress jpg and png on the client side 100% with javascript and no external libraries required!
You can try the demo here : http://makeitsolutions.com/labs/jic and get the sources here : https://github.com/brunobar79/J-I-C

If you look at the PHP constant [PATH_SEPARATOR][1], you will see it being ":" for you.
If you break apart your string ".:/usr/share/pear:/usr/share/php" using that character, you will get 3 parts
Any attempts to include()/require() things, will look in these directories, in this order.
It is showing you that in the error message to let you know where it could NOT find the file you were trying to require()
That was the cause of error.
Now coming to solution
php --ini
( in my case : /etc/php5/cli/php.ini
)include_path
in vi using esc
then press /include_path
then enter
include_path = ".:/usr/share/php:/var/www/<directory>/"
sudo service apache2 restart
This is it. Hope it helps.
maybe you forget to add parameter dataType:'json' in your $.ajax
$.ajax({
type: "POST",
dataType: "json",
url: url,
data: { get_member: id },
success: function( response )
{
//some action here
},
error: function( error )
{
alert( error );
}
});
The easiest way to convert back it in PowerShell
[System.Net.NetworkCredential]::new("", $SecurePassword).Password
You could do this:
find ./ -type f -ls |grep '10 Sep'
Example:

Clickatell is a popular SMS gateway. It works in 200+ countries.
Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.
The HTTP/S method is as simple as this:
http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here
The SMTP method consists of sending a plain-text e-mail to: [email protected]
, with the following body:
user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567
text: Meet me at home
You can also test the gateway (incoming and outgoing) for free from your browser
"user.dir" is the current working directory, not the home directory It is all described here.

Also, by using \\
instead of File.separator, you will lose portability with *nix system which uses /
for file separator.
Beside the fact, that push_back(x)
does the same as insert(x, end())
(maybe with slightly better performance), there are several important thing to know about these functions:
push_back
exists only on BackInsertionSequence
containers - so, for example, it doesn't exist on set
. It couldn't because push_back()
grants you that it will always add at the end.FrontInsertionSequence
and they have push_front
. This is satisfied by deque
, but not by vector
.insert(x, ITERATOR)
is from InsertionSequence
, which is common for set
and vector
. This way you can use either set
or vector
as a target for multiple insertions. However, set
has additionally insert(x)
, which does practically the same thing (this first insert in set
means only to speed up searching for appropriate place by starting from a different iterator - a feature not used in this case).Note about the last case that if you are going to add elements in the loop, then doing container.push_back(x)
and container.insert(x, container.end())
will do effectively the same thing. However this won't be true if you get this container.end()
first and then use it in the whole loop.
For example, you could risk the following code:
auto pe = v.end();
for (auto& s: a)
v.insert(pe, v);
This will effectively copy whole a
into v
vector, in reverse order, and only if you are lucky enough to not get the vector reallocated for extension (you can prevent this by calling reserve()
first); if you are not so lucky, you'll get so-called UndefinedBehavior(tm). Theoretically this isn't allowed because vector's iterators are considered invalidated every time a new element is added.
If you do it this way:
copy(a.begin(), a.end(), back_inserter(v);
it will copy a
at the end of v
in the original order, and this doesn't carry a risk of iterator invalidation.
[EDIT] I made previously this code look this way, and it was a mistake because inserter
actually maintains the validity and advancement of the iterator:
copy(a.begin(), a.end(), inserter(v, v.end());
So this code will also add all elements in the original order without any risk.
This is the piece of code from jquery.js which executes when is(":visible") is called :
if (jQuery.expr && jQuery.expr.filters){
jQuery.expr.filters.hidden = function( elem ) {
return ( elem.offsetWidth === 0 && elem.offsetHeight === 0 ) || (!jQuery.support.reliableHiddenOffsets && ((elem.style && elem.style.display) || jQuery.css( elem, "display" )) === "none");
};
jQuery.expr.filters.visible = function( elem ) {
return !jQuery.expr.filters.hidden( elem );
};
}
As you can see, it uses more than just the CSS display property. It also depends on the width and height of content of the element. Hence, make sure the element has some width and height. And for doing this, you may need to set the display property to "inline-block"
or "block"
Try this:
$categories = Category::all()->sortByDesc("created_at");
Using regexes for this purpose is the wrong approach. Since you are using python you have a really awesome library available to extract parts from HTML documents: BeautifulSoup.
You can use insert
:
a = [1,2,3]
a.insert(0,'x')
=> ['x',1,2,3]
Where the first argument is the index to insert at and the second is the value.
Not absolutely what you are asking for, but you may be interested by my plugin vim-notebook which allows the user to keep a background process alive and to make it evaluate part of the current document (and to write the output in the document). It is intended to be used on notebook-style documents containing pieces of code to be evaluated.
Normally you can't DELETE from multiple tables at once, unless you'll use JOINs as shown in other answers.
However if all yours tables starts with certain name, then this query will generate query which would do that task:
SELECT CONCAT('DELETE FROM ', GROUP_CONCAT(TABLE_NAME SEPARATOR ' WHERE user_id=123;DELETE FROM ') , 'FROM table1;' ) AS statement FROM information_schema.TABLES WHERE TABLE_NAME LIKE 'table%'
then pipe it (in shell) into mysql command for execution.
For example it'll generate something like:
DELETE FROM table1 WHERE user_id=123;
DELETE FROM table2 WHERE user_id=123;
DELETE FROM table3 WHERE user_id=123;
More shell oriented example would be:
echo "SHOW TABLES LIKE 'table%'" | mysql | tail -n +2 | xargs -L1 -I% echo "DELETE FROM % WHERE user_id=123;" | mysql -v
If you want to use only MySQL for that, you can think of more advanced query, such as this:
SET @TABLES = (SELECT GROUP_CONCAT(TABLE_NAME) FROM information_schema.TABLES WHERE TABLE_NAME LIKE 'table%');
PREPARE drop_statement FROM 'DELETE FROM @tables';
EXECUTE drop_statement USING @TABLES;
DEALLOCATE PREPARE drop_statement;
The above example is based on: MySQL – Delete/Drop all tables with specific prefix.
another option would be to give the span display:table;
and center it via margin:0 auto;
span {
display:table;
margin:0 auto;
}
You can simply use a controller method like this:
@RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
@ResponseBody
public ResponseEntity<?> uploadFile(
@RequestParam("file") MultipartFile file) {
try {
// Handle the received file here
// ...
}
catch (Exception e) {
return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
}
return new ResponseEntity<>(HttpStatus.OK);
} // method uploadFile
Without any additional configurations for Spring Boot.
Using the following html form client side:
<html>
<body>
<form action="/uploadFile" method="POST" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" value="Upload">
</form>
</body>
</html>
If you want to set limits on files size you can do it in the application.properties
:
# File size limit
multipart.maxFileSize = 3Mb
# Total request size for a multipart/form-data
multipart.maxRequestSize = 20Mb
Moreover to send the file with Ajax take a look here: http://blog.netgloo.com/2015/02/08/spring-boot-file-upload-with-ajax/
Just use
$('#SelectBoxId option:selected').text();
for getting the text as listed
$('#SelectBoxId').val();
for getting the selected index value
If you can re-structure your code so that you do not need to postback, then you can use this code in the PreRender event of the button:
protected void MyButton_OnPreRender(object sender, EventArgs e)
{
string URL = "~/MyPage.aspx";
URL = Page.ResolveClientUrl(URL);
MyButton.OnClientClick = "window.open('" + URL + "'); return false;";
}
It's a very old post, but if it benefits anyone, we can do something like this:
Long max=((BigInteger) Collections.max(dynamics)).longValue();
The problem is on this line:
oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"
Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:
oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "
You also have a typo in S:Claims\Sound.wav
, should be S:\Claims\Sound.wav
.
I also assume the apostrophe before Dim oShell
and after Set oShell = Nothing
are typos as well.
How will the browser know when to run the code inside script tag? So, to make the code run after the window is loaded completely,
window.onload = doStuff;
function doStuff() {
var e = document.getElementById("db_info");
e.innerHTML='Found you';
}
The other alternative is to keep your <script...</script>
just before the closing </body>
tag.
There're no packets in TCP API.
There're packets in underlying protocols often, like when TCP is done over IP, which you have no interest in, because they have nothing to do with the user except for very delicate performance optimizations which you are probably not interested in (according to the question's formulation).
If you ask what is a maximum number of bytes you can send()
in one API call, then this is implementation and settings dependent. You would usually call send() for chunks of up to several kilobytes, and be always ready for the system to refuse to accept it totally or partially, in which case you will have to manually manage splitting into smaller chunks to feed your data into the TCP send() API.
Turn the string into array, cut a character at specified index and turn back to string
let str = 'Hello World'.split('')
str.splice(3, 1)
str = str.join('')
// str = 'Helo World'.

select count(*) as count,dept.DNAME
from emp
inner join dept on emp.DEPTNO = dept.DEPTNO
group by dept.DNAME
X
is a dataframe and can't be accessed via slice terminology like X[:, 3]
. You must access via iloc

dataset = pd.DataFrame(np.random.rand(10, 10))
y=dataset.iloc[:, 4]
X=dataset.iloc[:, 0:4]
# Encoding categorical data
from sklearn.preprocessing import LabelEncoder, OneHotEncoder
labelencoder_X = LabelEncoder()
# I changed this line
X.values[:, 3] = labelencoder_X.fit_transform(X.values[:, 3])
Try this:

This might not be the exact thing you are looking for, but you can create a very similar effect by using rgba
in combination with linear-gradient
:
background: linear-gradient(rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%);
This creates a linear-gradient from black with 50% opacity (rgba(0,0,0,.5)
) to transparent (rgba(0,0,0,0)
) which starts being competently transparent 30% from the top. You can play with those values to create your desired effect. You can have it on a different side by adding a deg-value (linear-gradient(90deg, rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%)
) or switching the colors around. If you want really complex shadows like different angles on different sides you could even start layering linear-gradient
.
Here is a snippet to see it in action:
.box {_x000D_
background: linear-gradient(rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%);_x000D_
}_x000D_
_x000D_
.text {_x000D_
padding: 20px;_x000D_
}
_x000D_
<div class="box">_x000D_
<div class="text">_x000D_
Lorem ipsum ...._x000D_
</div>_x000D_
</div>
_x000D_

// bar.h
namespace baz

Depends on what you're hashing. If your keys are integers you probably don't need very many items before the HashSet is faster. If you're keying it on a string then it will be slower, and depends on the input string.
Surely you could whip up a benchmark pretty easily?
Try doing this if you're running Visual Studio Code on a Windows machine and getting this error (I'm using Windows 10).
Go to the settings and change the Python path to the location of YOUR python installation.
I.e.,
Change: "python.pythonPath": "python"
To: "python.pythonPath": "C:\\Python36\\python.exe"
And then: Save and reload Visual Studio Code.
Now when you get the prompt telling you that "Linter pylint is not installed", just select the option to 'install pylint'.
Since you've now provided the correct path to your Python installation, the Pylint installation will be successfully completed in the Windows PowerShell Terminal.
1) Are you sure mod_rewrite module is enabled? Check phpinfo()
2) Your above rule assumes the URL starts with "folder". Is this correct? Did you acutally want to have folder in the URL? This would match a URL like:
/folder/thing -> /folder/thing.php
If you actually want
/thing -> /folder/thing.php
You need to drop the folder from the match expression.
I usually use this to route request to page without php (but yours should work which leads me to think that mod_rewrite may not be enabled):
RewriteRule ^([^/\.]+)/?$ $1.php [L,QSA]
3) Assuming you are declaring your rules in an .htaccess file, does your installation allow for setting Options (AllowOverride) overrides in .htaccess files? Some shared hosts do not.
When the server finds an .htaccess file (as specified by AccessFileName) it needs to know which directives declared in that file can override earlier access information.
The inherit
value, when used, means that the value of the property is set to the value of the same property of the parent element. For the root element (in HTML documents, for the html
element) there is no parent element; by definition, the value used is the initial value of the property. The initial value is defined for each property in CSS specifications.
The font-family
property is special in the sense that the initial value is not fixed in the specification but defined to be browser-dependent. This means that the browser’s default font family is used. This value can be set by the user.
If there is a continuous chain of elements (in the sense of parent-child relationships) from the root element to the current element, all with font-family
set to inherit
or not set at all in any style sheet (which also causes inheritance), then the font is the browser default.
This is rather uninteresting, though. If you don’t set fonts at all, browsers defaults will be used. Your real problem might be different – you seem to be looking at the part of style sheets that constitute a browser style sheet. There are probably other, more interesting style sheets that affect the situation.
t
returns the number of days in the month of a given date (see the docs for date
):
$a_date = "2009-11-23";
echo date("Y-m-t", strtotime($a_date));
The number 0
in {0:X}
refers to the position in the list or arguments. In this case 0
means use the first value, which is Blue
. Use {1:X}
for the second argument (Green
), and so on.
colorstring = String.Format("#{0:X}{1:X}{2:X}{3:X}", Blue, Green, Red, Space);
The syntax for the format parameter is described in the documentation:
Format Item Syntax
Each format item takes the following form and consists of the following components:
{ index[,alignment][:formatString]}
The matching braces ("{" and "}") are required.
Index Component
The mandatory index component, also called a parameter specifier, is a number starting from 0 that identifies a corresponding item in the list of objects. That is, the format item whose parameter specifier is 0 formats the first object in the list, the format item whose parameter specifier is 1 formats the second object in the list, and so on.
Multiple format items can refer to the same element in the list of objects by specifying the same parameter specifier. For example, you can format the same numeric value in hexadecimal, scientific, and number format by specifying a composite format string like this: "{0:X} {0:E} {0:N}".
Each format item can refer to any object in the list. For example, if there are three objects, you can format the second, first, and third object by specifying a composite format string like this: "{1} {0} {2}". An object that is not referenced by a format item is ignored. A runtime exception results if a parameter specifier designates an item outside the bounds of the list of objects.
Alignment Component
The optional alignment component is a signed integer indicating the preferred formatted field width. If the value of alignment is less than the length of the formatted string, alignment is ignored and the length of the formatted string is used as the field width. The formatted data in the field is right-aligned if alignment is positive and left-aligned if alignment is negative. If padding is necessary, white space is used. The comma is required if alignment is specified.
Format String Component
The optional formatString component is a format string that is appropriate for the type of object being formatted. Specify a standard or custom numeric format string if the corresponding object is a numeric value, a standard or custom date and time format string if the corresponding object is a DateTime object, or an enumeration format string if the corresponding object is an enumeration value. If formatString is not specified, the general ("G") format specifier for a numeric, date and time, or enumeration type is used. The colon is required if formatString is specified.
Note that in your case you only have the index and the format string. You have not specified (and do not need) an alignment component.
You are able to cut all odd/even columns by using seq:
This would print all odd columns
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 1 2 10)
To print all even columns you could use
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 2 2 10)
By changing the second number of seq you can specify which columns to be printed.
If the specification which columns to print is more complex you could also use a "one-liner-if-clause" like
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(for i in $(seq 1 10); do if [[ $i -lt 10 && $i -lt 5 ]];then echo -n $i,; else echo -n $i;fi;done)
This would print all columns from 1 to 5 - you can simply modify the conditions to create more complex conditions to specify weather a column shall be printed.
Use Char.MinValue
which works the same as '\0'. But be careful it is not the same as String.Empty
.
If you ignore the characteristics of both languages, how do you define "SPEED"? Which features should be in your benchmark and which do you want to omit?
For example:
Conclusion: Your question has no answer because it isn't defined what you want. Even if you made it more clear, the question will probably become academic since you will measure something that doesn't count in real life. For all of my projects, both Java and Python have always been fast enough. Of course, I would prefer one language over the other for a specific problem in a certain context.

If you need to remove the HTML but does not know if it actually contains any HTML tags, you can't use the jQuery method directly because it returns empty wrapper for non-HTML text.
$('<div>Hello world</div>').text(); //returns "Hello world"
$('Hello world').text(); //returns empty string ""
You must either wrap the text in valid HTML:
$('<div>' + 'Hello world' + '</div>').text();
Or use method $.parseHTML() (since jQuery 1.8) that can handle both HTML and non-HTML text:
var html = $.parseHTML('Hello world'); //parseHTML return HTMLCollection
var text = $(html).text(); //use $() to get .text() method
Plus parseHTML removes script tags completely which is useful as anti-hacking protection for user inputs.
$('<p>Hello world</p><script>console.log(document.cookie)</script>').text();
//returns "Hello worldconsole.log(document.cookie)"
$($.parseHTML('<p>Hello world</p><script>console.log(document.cookie)</script>')).text();
//returns "Hello world"
form
If the name attribute is specified, the form controller is published onto the current scope under this name.
Alias: ngForm
In Angular, forms can be nested. This means that the outer form is valid when all of the child forms are valid as well. However, browsers do not allow nesting of elements, so Angular provides the ngForm directive which behaves identically to but can be nested. This allows you to have nested forms, which is very useful when using Angular validation directives in forms that are dynamically generated using the ngRepeat directive. Since you cannot dynamically generate the name attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an ngForm directive and nest these in an outer form element.
CSS classes
ng-valid is set if the form is valid.
ng-invalid is set if the form is invalid.
ng-pristine is set if the form is pristine.
ng-dirty is set if the form is dirty.
ng-submitted is set if the form was submitted.
Keep in mind that ngAnimate can detect each of these classes when added and removed.
Submitting a form and preventing the default action
Since the role of forms in client-side Angular applications is different than in classical roundtrip apps, it is desirable for the browser not to translate the form submission into a full page reload that sends the data to the server. Instead some javascript logic should be triggered to handle the form submission in an application-specific way.
For this reason, Angular prevents the default action (form submission to the server) unless the element has an action attribute specified.
You can use one of the following two ways to specify what javascript method should be called when a form is submitted:
ngSubmit directive on the form element
ngClick directive on the first button or input field of type submit (input[type=submit])
To prevent double execution of the handler, use only one of the ngSubmit or ngClick directives.
This is because of the following form submission rules in the HTML specification:
If a form has only one input field then hitting enter in this field triggers form submit (ngSubmit)
if a form has 2+ input fields and no buttons or input[type=submit]
then hitting enter doesn't trigger submit
if a form has one or more input fields and one or more buttons or input[type=submit]
then hitting enter in any of the input fields will trigger the click handler on the first button or input[type=submit]
(ngClick) and a submit handler on the enclosing form (ngSubmit).
Any pending ngModelOptions changes will take place immediately when an enclosing form is submitted. Note that ngClick events will occur before the model is updated.
Use ngSubmit to have access to the updated model.
app.js:
angular.module('formExample', [])
.controller('FormController', ['$scope', function($scope) {
$scope.userType = 'guest';
}]);
Form:
<form name="myForm" ng-controller="FormController" class="my-form">
userType: <input name="input" ng-model="userType" required>
<span class="error" ng-show="myForm.input.$error.required">Required!</span>
userType = {{userType}}
myForm.input.$valid = {{myForm.input.$valid}}
myForm.input.$error = {{myForm.input.$error}}
myForm.$valid = {{myForm.$valid}}
myForm.$error.required = {{!!myForm.$error.required}}
</form>

Elegant easy solution using jQuery.
<script>
function call() {
var body = $("html, body");
body.stop().animate({scrollTop:0}, 500, 'swing', function() {
});
}
</script>
and in your html :
<div onclick="call()"><img src="../img/[email protected]"></div>
MSK,
Have you tried setting a namespace declaration to your member variables like this? :
@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;
@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;
For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.
you can 'invoke' alternative bindings on Y
this way:
...registered(X, Y), (Y=ct101; Y=ct102; Y=ct103).
Note the parenthesis are required to keep the correct execution control flow. The ;
/2 it's the general or
operator. For your restricted use you could as well choice the more idiomatic
...registered(X, Y), member(Y, [ct101,ct102,ct103]).
that on backtracking binds Y to each member of the list.
edit I understood with a delay your last requirement. If you want that Y match all 3 values the or is inappropriate, use instead
...registered(X, ct101), registered(X, ct102), registered(X, ct103).
or the more compact
...findall(Y, registered(X, Y), L), sort(L, [ct101,ct102,ct103]).
findall/3 build the list in the very same order that registered/2 succeeds. Then I use sort to ensure the matching.
...setof(Y, registered(X, Y), [ct101,ct102,ct103]).
setof/3 also sorts the result list
A little late but I believe some further clarification is given below.
You can iterate through a JSON array with a simple loop as well, like:
for(var i = 0; i < jsonArray.length; i++)
{
console.log(jsonArray[i].attributename);
}
If you have a JSON object and you want to loop through all of its inner objects, then you first need to get all the keys in an array and loop through the keys to retrieve objects using the key names, like:
var keys = Object.keys(jsonObject);
for(var i = 0; i < keys.length; i++)
{
var key = keys[i];
console.log(jsonObject.key.attributename);
}
You don't need to do anything, the Model Binding
will pass null
to property without any problem.
Had same problem. Just did a quick look up apache2 error.log
file and it said exactly what was the problem:
> sh: /usr/sbin/sendmail: Permission denied
So, the solution was to give proper permissions for /usr/sbin/sendmail
file (it wasn't accessible from php).
Command to do this would be:
> chmod 777 /usr/sbin/sendmail
be sure that it even exists!
If changing size or after loading some data it is adding the scroll bar then you can try following, create class and apply this class.
.auto-scroll {
overflow-y: overlay;
overflow-x: overlay;
}
This approach can be used in case commands 'ps', 'pidof' and rest are not available. I personally use procfs very frequently in my tools/scripts/programs.
egrep -m1 "mysqld$|httpd$" /proc/[0-9]*/status | cut -d'/' -f3
Little explanation what is going on:
For a portable (ISO C90) implementation, you could use double parentheses, like this;
#include <stdio.h>
#include <stdarg.h>
#ifndef NDEBUG
# define debug_print(msg) stderr_printf msg
#else
# define debug_print(msg) (void)0
#endif
void
stderr_printf(const char *fmt, ...)
{
va_list ap;
va_start(ap, fmt);
vfprintf(stderr, fmt, ap);
va_end(ap);
}
int
main(int argc, char *argv[])
{
debug_print(("argv[0] is %s, argc is %d\n", argv[0], argc));
return 0;
}
or (hackish, wouldn't recommend it)
#include <stdio.h>
#define _ ,
#ifndef NDEBUG
# define debug_print(msg) fprintf(stderr, msg)
#else
# define debug_print(msg) (void)0
#endif
int
main(int argc, char *argv[])
{
debug_print("argv[0] is %s, argc is %d"_ argv[0] _ argc);
return 0;
}
You can use the following wrap to make sync call
this.setState((state =>{_x000D_
return{_x000D_
something_x000D_
}_x000D_
})
_x000D_
public class MainActivity extends AppCompatActivity {
public void clickMe (View view) {
MediaPlayer mp = MediaPlayer.create(this, R.raw.xxx);
mp.start();
}
create a button with a method could be called when the button pressed (onCreate),
then create a variable for (MediaPlayer) class with the path of your file
MediaPlayer mp = MediaPlayer.create(this, R.raw.xxx);
finally run start method in that class
mp.start();
the file will run when the button pressed, hope this was helpful!
>>> foo = 'BS1 1AB'
>>> foo.replace(" ", "").rstrip()[:-3].upper()
'BS1'
Take a look at the JSONObject reference:
http://www.json.org/javadoc/org/json/JSONObject.html
Without actually using the object, it looks like using either getNames() or keys() which returns an Iterator is the way to go.
You can also use:
CFGregorianDate currentDate = CFAbsoluteTimeGetGregorianDate(CFAbsoluteTimeGetCurrent(), CFTimeZoneCopySystem());
countdownLabel.text = [NSString stringWithFormat:@"%02d:%02d:%02.0f", currentDate.hour, currentDate.minute, currentDate.second];
CFRelease(currentDate); // Don't forget this! VERY important
I think this has the following advantages:
I found this related question: Directory Listing in S3 Static Website
As it turns out, if you enable public read for the whole bucket, S3 can serve directory listings. Problem is they are in XML instead of HTML, so not very user-friendly.
There are three ways you could go for generating listings:
Generate index.html files for each directory on your own computer, upload them to s3, and update them whenever you add new files to a directory. Very low-tech. Since you're saying you're uploading build files straight from Travis, this may not be that practical since it would require doing extra work there.
Use a client-side S3 browser tool.
Use a server-side browser tool.
There are a number of ways to make Python speak in both Python3 and Python2, two great methods are:
If you are on mac you will have the os module built into your computer. You can import the os module using:
import os
You can then use os to run terminal commands using the os.system command:
os.system("Your terminal")
In terminal, the way you make your computer speak is using the "say" command, thus to make the computer speak you simply use:
os.system("say 'some text'")
If you want to use this to speak a variable you can use:
os.system("say " + myVariable)
The second way to get python to speak is to use
You will have to install this using
pip isntall pyttsx3
or for Python3
pip3 install pyttsx3
You can then use the following code to get it to speak:
import pyttsx3
engine = pyttsx3.init()
engine.say("Your Text")
engine.runAndWait()
I hope this helps! :)
I found it's better to set the width
and height
to 0px
. Otherwise, IE10 ignores the padding defined on the field -- padding-right
-- which was intended to keep the text from typing over the 'X' icon that I overlayed on the input field. I'm guessing that IE10 is internally applying the padding-right
of the input to the ::--ms-clear
pseudo element, and hiding the pseudo element does not restore the padding-right
value to the input
.
This worked better for me:
.someinput::-ms-clear {
width : 0;
height: 0;
}
Like this:
long begin, end;
ifstream myfile ("example.txt");
begin = myfile.tellg();
myfile.seekg (0, ios::end);
end = myfile.tellg();
myfile.close();
cout << "size: " << (end-begin) << " bytes." << endl;
Check to make sure that the file is complete. This error message can occur if you only partially downloaded a file or if it has major issues. Check the MD5sum.
That won't work if the string contains more than one match... try this:
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo " $0) }'
or better (if the echo
isn't a placeholder for something else):
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'
In your case you want to make a copy of the value before changing it:
echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'
You'll need to use a static
readonly
list instead. And if you want the list to be immutable then you might want to consider using ReadOnlyCollection<T>
rather than List<T>
.
private static readonly ReadOnlyCollection<string> _metrics =
new ReadOnlyCollection<string>(new[]
{
SourceFile.LOC,
SourceFile.MCCABE,
SourceFile.NOM,
SourceFile.NOA,
SourceFile.FANOUT,
SourceFile.FANIN,
SourceFile.NOPAR,
SourceFile.NDC,
SourceFile.CALLS
});
public static ReadOnlyCollection<string> Metrics
{
get { return _metrics; }
}
